This invention relates to a skirting board, a floor covering system, in particular a floor covering system applying such skirting board, and a method for manufacturing such skirting board.
It is known that a floor covering can be formed by means of floor panels which are laid on a subfloor and preferably are mutually joined either by means of a glued-together tongue and groove coupling, or by means of coupling parts effecting an interlocking of the floor panels. Examples of mechanically locking coupling parts, which are integrated in the floor panels, are known, amongst others, from the international patent applications WO 97/47834, WO 01/98603 and WO 01/96688.
Such floor panels may be of various construction, whereby mostly, use is made of a substrate or core, on top of which a top layer, whether or not formed of several layers, is provided. The core mostly consists of a plate of a wood-based material, for example, fibreboard or chipboard, more particularly MDF (Medium Density Fibreboard) or HDF (High Density Fibreboard), although the use of other materials for the core, for example, synthetic material, so-called compact laminate and the like, is not excluded. The top layer may be realized on the basis of synthetic material or another material, for example, veneer, a wood layer with a thickness of several millimetres, cork, linoleum, stone or the like.
In case the top layer consists of veneer or a wood layer with a thickness of several millimetres, a skirting board pertaining to the flooring can simply be realized from solid wood of the same kind of wood as the veneer of the top layer.
In the case that the top layer of the floor panels is realized on the basis of synthetic material, for example, is formed of one or more pressed and cured resin-impregnated carrier sheets, amongst which a printed decor layer, which are provided on a core layer, more particularly DPL (Direct Pressure Laminate) or HPL (High Pressure Laminate), the problem arises that it is rather difficult to realize a skirting board that is optimally matched to the flooring, and such in a industrially and economically responsible manner.
Up to now, in combination with such floor panels skirting boards are applied that are covered by a printed film, whereby said film is glued onto the actual skirting board. Those known skirting boards show the disadvantage that the print of the film of the skirting board is never optimally matched to the print of the decor layer of the floor panels, in view of the fact that usually, one starts from different manufacturing and printing techniques and furthermore such film and decorative layer also are realized at different manufacturers'. Besides, developing a new adapted print for the film of the skirting boards for each newly developed pattern for the decor layer is expensive. Another disadvantage of such film-covered skirting boards consists in that, due to the nature of the film material, namely, simply printed paper or synthetic material, they never show one and the same appearance as the surface of the floor panels that is obtained by means of a pressing and curing procedure.
Also, such film does not allow to realize well-defined effects on the surface, which indeed are possible when manufacturing the floor panels, such as providing impressions, whether or not in register with the underlying printed pattern, providing impressions which are filled with a colour component or another component, finishing the surface, for example, glossing it, and so on.
Another important disadvantage of such film-covered skirting board consists in that it is impossible to realize skirting boards whereby the front side and the upper side adjoin each other at an angle, because, when applying a covering film, always a certain rounding radius must be provided.
From the patent documents FR 2.192.895 and FR 1.530.769, it is also known to provide covered plates with an edge covering. The manufacturing of such plates, however, is situated in another technical field than the production of skirting boards, resulting in that the skilled person will not see an evident solution for constructing skirting boards in the aforementioned documents.
The present invention aims at a skirting board which is constructed such that a solution for one or more of the aforementioned disadvantages is provided.
According to a first aspect, the invention thus relates to a skirting board with the characteristic that it consists of at least two structural parts, a first part forming at least a portion of the front side, and a second part forming at least a portion of the upper side of the skirting board, respectively, whereby both parts are formed from a laminate material formed by means of pressing power, with a core and, provided thereupon, a top layer on the basis of synthetic material. As the skirting board according to the invention is composed of two parts each consisting of a laminate material, the realization of the skirting board of the invention is no longer restricted by the limitations of the use of a covering film, and all effects can be created that are possible with the floor panels, too. Also, it is possible to realize skirting boards with a front side and an upper side mutually adjoining at an angle, without having to take a rounding radius into account. Also, the skirting board according to the invention has a surface quality entirely corresponding to that of the floor panels.
It is noted that by structural parts, it is meant that these parts have a core or substrate, on top of which a top layer is provided, contrary to, for example, thin laminate ribbons which sometimes are used for covering the lateral edge of a laminate board. Basically, such laminate ribbons might also be used for covering the upper side of a skirting board, however, it is known from practice that the use of such laminate ribbons in general has the disadvantage that they can loosen very easily and that the connection with the front side is not always perfect.
Preferably, said two parts are formed of a plate-shaped material, with the advantage that this material can be manufactured in one and the same production process or a similar production process as the basic board from which floor panels are formed. Thereby, the basic material of the skirting boards can be manufactured, for example, with the same presses as those applied for manufacturing the floor panels, without the necessity of taking particular measures when pressing.
Preferably, said two parts are manufactured of a similar or one and the same laminate material and are provided with one and the same pattern, such that, consequently, the appearance of the front and upper sides completely match each other. More particularly, it is preferred that said two parts originate from one and the same laminate plate, such that possible minor differences that, for which reasons whatever, might occur in the production of subsequent laminate plates, never result in differences between the front and upper sides of one and the same skirting board.
In the most preferred form of embodiment, said two parts adjoin each other at least at the height of the outer side of the skirting board, and they show patterns at their visible sides which fade into each other, whereby, for example, in the case of a wood motive, it is obtained that the grain of the wood at the upper side fades into the grain of the wood at the front side, which creates an appearance as if the skirting board consisted of solid wood.
In the first place, the invention is useful with classical laminate of the type whereby the top layer of said two parts is formed of one or more pressed, resin-immersed layers, amongst which a so-called decor layer that is printed either with a uniform print or with a well-defined pattern imitating, for example, wood, ceramics, stone or the like. More particularly, it is preferred that said laminate material of at least one of said two parts, and preferably of both parts, consists of so-called DPL (Direct Pressure Laminate) or so-called HPL (High Pressure Laminate) that is attached to a substrate or core.
The aforementioned two parts can be attached to each other directly or indirectly, for example, by means of glue or in any other manner.
As aforementioned, the skirting board according to the invention can be realized without a rounding between the front and upper sides, whereas the decorative top layers still adjoin each other. Therefore, according to a preferred form of embodiment, said two parts with their outer sides will adjoin each other at an angle.
According to an important preferred form of embodiment, said two parts extend with their top layer at an angle of 90 degrees in respect to each other, whereby thus a skirting board with a rectangular outer side is obtained.
Preferably, said two parts at least partially adjoin each other with a mitre joint, whereby this mitre joint preferably extends at least up to the outer side of the skirting board. Hereby, at least in those embodiments in which said parts are situated directly against each other, an adjoining of the top layers in the external angle of the skirting board without visible seams is obtained. Hereby, the mitre preferably extends according to an angle coinciding or approximately coinciding with the bisecting line of the external angle of the skirting board. However, other possibilities are not excluded.
In a particular form of embodiment, the top layer of at least one of said parts, however, preferably of both parts, is provided with impressions, more particularly impressions imitating a relief, for example, of a natural material, such as wood pores, unevenness of a stone surface or the like. Hereby, these impressions possibly may correspond to the pattern, more particularly the printed pattern, of the top layer, which often is called “registered embossment”. This latter is particularly useful when imitating wood, because in this manner a very realistic imitation can be obtained.
According to another particular form of embodiment, use is made of a laminate material, whereby in said impressions, or at least in a part thereof, a component is provided in the form of a colouring product and/or an active component. By means of such colouring product, special effects can be realized that also are applied for floor panels, such as, for example, imitating lime-washed wood. By using an active component, other effects can be created. By an active component, amongst others, anti-bacterial, mildewproofing, fluorescent, antistatic, sound dampening and other components are to be understood.
According to another particular form of embodiment, parts are used whereby the top layer comprises a decor layer, whereby above the decor layer, whether or not directly thereupon, at least one coloured overlay is present, which also allows to realize particular effects, as this is the case with floor panels.
So, for example, a very realistic imitation of coloured, and more particularly lime-washed wood, also called “cérusé”, can be obtained by forming the parts of a material having a top layer with a decor layer representing a wood pattern, whereby this top layer is provided with impressions in which a colouring component is applied, and moreover by applying a coloured overlay. The impressions, filled with the colouring component, imitate the colour remaining in the pores of a coloured real wooden floor, whereas the coloured overlay imitates the thin tinge of colour remaining on the smooth wood surface when colouring real wood.
In respect to said impressions, the use of components in these impressions, the use of coloured overlays, as well as performing special finishing operations, such as the glossing of the surface of the top layer, reference is made to the patent applications WO 01/96689, BE 2003/0339 and BE 2003/0585, whereby the information which is given in these patent applications, although described for floor panels, should be considered incorporated by reference in the present application, however, as being applied to said skirting board.
According to a particular possibility, at the height of the corner edge formed by said two parts, a material part is removed, preferably in the form of a bevelled edge, whereby then a decorative layer is applied on the obtained surface, for example, in the form of a lacquer, varnish, impregnating agent, whether or not coloured, transfer print or other print.
It is clear that the core of said parts preferably consists of the same material as the core material applied when manufacturing floor panels. In the most preferred form of embodiment thus MDF or HDF are used. MDF and HDF also show the advantage of being materials that are easy to machine, which is important when forming said two parts.
In principle, said core may consist of any material. Other examples thus are particle board, extruded wood, extruded paper pulp or other board materials, whether or not on the basis of wood. In the case of extruded wood or paper pulp, it is not excluded to start from basic parts, which already are extruded in the shape of the final skirting board, or more or less in the shape thereof, and are laminated afterwards in order to arrive at the two structural parts.
In the case that a hydrophilic material, as, for example, MDF/HDF is used, the bottom side of the skirting board possibly can be treated with a hydrophobic material, a sealing material, or the like.
Preferably, said two parts respectively consist of a larger standing part forming the front side of the skirting board and a smaller top part provided on top of the standing part and forming the upper side of the skirting board.
For practical reasons, it is preferred that said two parts are formed of plate-shaped material and that the sides of those parts facing each other are realized by means of a machining operation, i.e. a material-cutting operation. In fact, board-shaped material, which has been obtained by means of processing by a press, is subjected to relatively large thickness tolerances. However, by attaching the two parts against each other exclusively with sides obtained by means of a machining operation, which operation can be realized with very small tolerance deviations, the influence of thickness tolerances of the original board-shaped material is avoided.
In an important preferred form of embodiment, the two parts are formed of a board-shaped material which, opposed to the top layer, also comprises a backing layer, whereby the part forming the lateral edge of the skirting board still comprises this backing layer, whereas the backing layer at the part forming the upper side of the skirting board has been removed.
Preferably, the components of the skirting board, and more particularly said two parts, have matching forms, for example, in the shape of a male and a female part, which, when joining these parts, effect an automatic mutual positioning. So, for example, the sides of the mutually adjoining parts can be realized with an internal angle, external angle, respectively, fitting into each other. When pressing the parts against each other, they consequently automatically are put in a correct mutual position, which excludes an imprecise adjoining of the top layers at the external corner of the skirting board.
Although the skirting board according to the invention preferably consists of only two parts, it is not excluded to compose it of more parts. Hereby, it is also possible to use a common support or connecting structure to which said two or more parts are attached. The same support or connecting structure then is preferably used for attaching the skirting board assembly at the wall, possibly by cooperation with other attachment accessories.
It is clear that the components of the skirting board, and more particularly said two parts, do not necessarily have to be attached to each other by means of a glue connection, but that any kind of connection can be applied for this purpose. According to a particular form of embodiment, thus two or more of the components, and more particularly said two parts, can be interconnected by means of profiled areas engaging each other, which preferably provide for a snap connection, whereby the use of glue or separate elements, such as staples, nails, screws or the like can be excluded.
It is clear that the skirting board can show a globally straight shape as well as any other shape. So, for example, it may be realized with a functional profiled rear side, as, for example, a rear side with a re-entering part in order to limit the contact with the wall or floor, a rear side that is intended to cooperate with one or more attachment accessories, such as attachment clips, a rear side that is provided with one or more recesses, for example, for accommodating cables, and so on. The recesses may be either continuous or discontinuous in the longitudinal direction. Preferably, the removed material of the profiled part at the rear side of the skirting board provides for a sufficient flexibility of the skirting board. This flexibility also allows for a proper adjoining of the skirting board in the longitudinal direction against an uneven or not straight wall. The space created in the rear side of the skirting board can be used when packaging the latter for accommodating the necessary attachment accessories therein.
The invention is not restricted to skirting boards with a classical appearance, in other words, skirting boards having a uniform appearance or continuous pattern continuing over their length. So, for example, the top layer of said two parts can be realized with a printed tile pattern with joints extending over the front side and upper side of the respective skirting board. Hereby, possibly at the height of the imitated joints, a relief difference may be present, which is preferably formed by an impression, removal of material or a recess. The relief difference whether or not can be combined with a difference in the surface structure. Possibly, only a difference in the surface structure can be applied for imitating the joint.
Another problem arising with traditional skirting boards that conventionally have a length of two or more meters, is that the application thereof may lead to certain disadvantages. So, for example, skirting boards of such classical length may easily be damaged during transport. Also, they are difficult to transport together with traditional laminated floor panels, as their length is considerably larger than the length of such floor panels.
When continuous skirting boards are realized with a repeated tile pattern, which skirting boards are intended for being used with tile-shaped laminated floor panels, also the disadvantage is created that it is difficult to create a skirting board in which the distance between the successive imitated joints corresponds to the distance between the imitated joints of the floor panels, in particular when one would start from a basic plate with one and the same tile pattern for forming the skirting board and forming the floor panels in accordance with the first aspect of the invention. As, when manufacturing the tile-shaped laminated floor panels, at the height of each joint a portion is sawn off and milled off, whereas this is not the case when manufacturing a continuous skirting board of the same material, it is clear that the distance differs between the joints of the skirting board and the joints of the floor panels. Thus, it is not possible to provide such skirting board having joints imitated thereupon in accordance with the joints of the floor panels along an installed floor.
Even if one would start for the skirting board from a basic plate with a separate decor layer, whereby the joints are represented closer to each other, the disadvantage remains that it is impossible to guarantee a perfect conformity between the joints on the skirting boards and the joints at the tile-shaped floor panels. In fact, such printed decor layer is subjected to extension and shrinkage, which renders it difficult to guarantee a fixed distance between the joints on the skirting board.
In order to remedy one or more of said disadvantages, according to a second aspect the present invention provides a skirting board, more particularly a skirting board with a laminated surface on one or more sides, which is characterized in that it is composed of short pieces, more particularly shorter than the aforementioned length of two meters, which can be mounted successively in longitudinal direction. It is clear that thereby industrially produced lengths of skirting boards are concerned.
According to a first possibility of this second aspect, one will work with pieces, the length of which is almost equal, equal to or shorter than the length of the floor panels with which the skirting board is intended to be applied. In this manner, rather short pieces are obtained, which, on the one hand, will less easily become damaged and, on the other hand, can be easily transported together with boxes of packaged floor tiles, either by sending them along therewith separately, whether or not in their own box, or by packaging them together with floor panels in on and the same box.
According to another possibility of the second aspect of the invention, the pieces are realized with such a length that they precisely correspond to the length of a tile-shaped floor panel, whereby then a joint is imitated at the extremities of each piece, with the result that a skirting board can be realized of such pieces whereby the joints can precisely correspond to the joints of the tile-shaped floor panels. In fact, said pieces can be manufactured with small length tolerances, like the tile-shaped floor panels, so that differences will hardly occur.
Also, it is not excluded to realize the length of the pieces with a multiple of the length of a tile.
It is clear that the present invention also relates to the pieces themselves of which such skirting board is composed.
According to a particular form of embodiment, the successive pieces can be provided with coupling means for coupling them, whether directly or not, to each other. Hereby, those may be coupling means on the extremities that engage each other and effect a mechanical locking, and/or coupling means with which each piece can be provided on a common underlying support structure, for example, a strip of MDF/HDF, synthetic material, metal or the like, or common attachment clips, whereby this support structure then, for example, first is attached to the wall.
The coupling means on the extremities may have different forms and consist, for example, of a tongue and groove, whether or not combined with locking means that also effect an interlocking in the longitudinal direction of the skirting board pieces.
According to another particular form of embodiment, the successive pieces are provided with positioning means, which are realized such that the successive pieces, due to their placement, automatically are aligned in mutual respect, or at least are aligned at least partially in mutual respect. The positioning means, for example, can realize a proper alignment of the upper sides and/or front sides of two skirting boards that are mounted against each other. According to a preferred form of embodiment, the successive pieces of the skirting board are provided with coupling means as well as positioning means, which, whether or not, are formed by means of the same parts.
According to a particular form of embodiment, the pieces of skirting board comprise, at their extremities, coupling means extending both parallel to the front side and parallel to the upper side, in such a manner that a locking in three directions is obtained, namely the two directions in the plane of the front side and the direction perpendicular to this front side.
Said imitation of a joint at the height of the extremities of said pieces of the skirting board can be realized in different ways. Preferably, this is performed according to one of the following possibilities:
- by means of a print;
- by means of an impression;
- by means of a print combined with an impression;
- by means of a removed material portion along the edge of the joint;
- by means of a removed material portion in the shape of an inclination or so-called bevel, upon which, whether or not, a separate decorative layer is provided;
- by means of a difference in surface structure between the joint and the tile pattern.
It is noted that the invention also relates to a skirting board whereby one or more characteristics of said first aspect are combined with one or more characteristics of said second aspect of the invention.
The present invention also relates to a floor covering system consisting of floor panels and skirting boards, whereby the floor panels are formed by laminated panels with a core and a top layer based on synthetic material, more particularly resin, pressed thereupon, preferably so-called DPL (Direct Pressure Laminate), with the characteristic that hereby skirting boards according to the first aspect of the invention are applied and that the top layers of the skirting boards and the floor panels are matched to each other.
Preferably, these top layers are matched to each other in that they show one or more of the following features:
- the skirting boards and the floor panels have been realized by a similar manufacturing process;
- both top layers consist of so-called DPL (Direct Pressure Laminate);
- the top layers are formed by means of identical decor layers, more particular identical paper layers printed with a pattern and impregnated with resin;
- the top layers are finished in a similar manner, more particular, both are provided with one or more of the following finishes:
- impressions in the surface;
- impressions in the surface, which are in register with the pattern of a decor layer applied in the top layer;
- impressions in the surface, in which a component is provided, either a colour component or an active component;
- a finishing treatment of the surface, whereby the feature thereof is altered, such as, amongst others, a glossed surface.
Further, the invention also relates to a method for manufacturing skirting boards according to said first aspect, whereby this method is characterized in that, by means of pressing power, a laminate material, with a core and a pressed-thereupon top layer on the basis of synthetic material, is formed; that from this laminate material, the aforementioned two parts are formed by means of one or more machining operations; and that said two parts are connected to each other directly or indirectly.
Preferably, hereby strips are formed of the laminate material; these strips are joined with a mitre joint and attached to each other; and subsequently portions are removed from the joined strips, more particularly, are sawn off, in order to obtain a skirting board. As the assembly takes place by means of larger strips, after which then a portion of one or both strips is sawn off, the strips can be properly clamped when assembling them.
According to a particular technique, said strips are assembled in a tubular shape, such that by sawing this tubular arrangement in a suitable manner, several skirting boards are obtained at a time. Such tubular structure offers the advantage that the different strips can easily be assembled until they are adhered to each other. It is noted that such tubular structure preferably, however, not necessarily, is realized with a square or rectangular shape.
According to another technique of the invention, one starts from a lath or strip, which preferably is sawn off a plate, whereby both longitudinal edges are provided with a profile, after which this lath is cut in longitudinal direction, for example, sawn, and the two obtained parts that formerly were situated at the longitudinal edges are assembled such that a skirting board in accordance with the invention is obtained.
According to a particular characteristic of the invention, the basic plates for forming said parts of the skirting board and the floor panels are realized by means of a similar manufacturing process, with the only essential difference that, for forming the parts of the skirting board, one starts from a plate-shaped material having a thicker core than the plate-shaped material used for forming the floor panels.
According to a preferred method, one starts from pieces of laminate material having coupling means at two opposite sides, such that, after assembling the two parts, also coupling means at the extremities of the skirting board are created.
More particularly, in case that the skirting board shows a tile pattern and the skirting board is intended for being used with a floor covering of the type consisting of separate floor panels, which in their turn each represent a tile, with or without imitation of a joint, a method is recommended whereby the structural parts of the skirting board are manufactured from panels of the respective floor covering. Such method provides for that the dimensions of the skirting board are identical to the dimensions of the floor, such that the possible imitation of a joint on the skirting board perfectly coincides with the same imitation on the floor covering. This method also provides for that the skirting board, at its extremities, will be provided with the same coupling means as the floor covering.
Although the use of a thin ribbon-shaped part at the upper side of the skirting board instead of a structural part, as aforementioned, leads to certain disadvantages, it is noted that the use of such ribbon-shaped part still can offer particular advantages when thinking about applying certain finishing treatments. Such finishing treatments might also be performed on a film, more particularly a thin laminate film, before and/or after such film has been cut to ribbons or strips, after which the obtained ribbons or strips are attached to the upper side of the skirting board. Hereby, not only the advantage is created that a laminated surface is obtained at the front side as well as at the upper side, but that similar treatments and, thus, effects can be created at those surfaces, which also can be optimally matched to the floor panels.
Also, it is not excluded to provide the front side of the skirting board with such film, or the upper side as well as the front side.
According to a third aspect, the invention thus also relates to a skirting board, characterized in that it has a laminated surface both at the front side and the upper side, which surface is obtained by means of a press operation, whereby at least one surface is formed by a previously formed laminate film, whereby both laminated surfaces have been subjected to one and the same or a similar finishing treatment.
The finishing treatments are, for example, one or more of the treatments described above, such as providing impressions that follow the pattern, filling the impressions with a component, glossing the panels and the like.
When the laminate film is combined with a classical laminate, for example, when the body of the skirting board and the front face are formed by a core with a top layer pressed thereupon, for example, of the DPL type, and the upper side consists of a subsequently adhered laminate film, preferably use is made of one and the same decor layer. Preferably, the laminate and the decor layer are realized in one and the same press, in the case of impressions even with one and the same press platen.
According to its fourth aspect, the present invention relates to a skirting board, with as a characteristic that it consists at least of a first part forming at least a portion of the front side of the skirting board, and a second part forming at least a portion of the upper side of the skirting board, whereby both parts are formed of the same piece of laminate material, with a core and a top layer of the DPL type, and whereby the second part consists of a part obtained in that a material portion is removed from the material of the core of the laminate material, whereby the first part and the second part have been brought together by turning them towards each other around a folding or breaking line.
The folding or breaking line preferably is determined by a locally weakened zone, although this does not necessarily have to be so. In the case of a locally weakened zone, the latter preferably is located at the rear side of the top layer, although the use of such weakened zone at the front side is not excluded.
Such skirting board has the advantage that the front side and the upper side of the skirting board may show continuous patterns. Moreover, the skirting board may be assorted with the floor covering, as it possibly may be manufactured of the same laminate material as the floor covering itself.
Another advantage with a skirting board according to the fourth aspect of the invention consists in that, due to the fact that for the top layer, DPL is applied, which latter, as known, is thin and brittle, a very fine fold or break can be obtained when turning the first and second parts towards each other.
In a preferred form of embodiment, the skirting board has the characteristic that said two parts are folded and/or broken in respect to each other around a folding or breaking line, which originally had been present as a weakened material zone partially realized up into the top layer. In the combined condition of said two parts, the realization of such weakened material zone up into the top layer results in that the quality of the edge where both parts adjoin each other is better than might be expected.
It is noted that the application of such weakened material zone partially extending up into the top layer also is useful when composing skirting boards with other kinds of top layers than DPL in the aforementioned manner, for example, also in the case of laminate materials with a top layer formed by HPL (High Pressure Laminate). The application of such weakened material zone extending partially up into the top layer, with any form of laminate, more particularly synthetic material laminate, thus can be seen as a particular additional aspect of the invention.
Further, the invention also relates to a method for manufacturing skirting boards according to said fourth aspect. To this aim, the invention relates to a method with as a characteristic that, by means of pressing power, a laminate material with a core and a pressed-thereupon top layer of the so-called DPL type is formed; that, for forming the skirting boards, one starts from laths or strips of said laminate material, whereby at least at one longitudinal edge of these laths, a material part is removed, such that said first and second parts are formed, whereby both parts remain connected at least by a portion of the top layer, and possibly by a weakened core portion below the top layer; and that said parts are turned towards each other and are joined and attached to each other.
Preferably, at least one of said parts is structural. Then, the second part consists at least of a portion of the top layer, whether or not provided with a portion of the core below the top layer.
Preferably, the two parts are gradually forced towards each other in a continuous process, whereby the second part, by means of a torsion movement, gradually is pushed into the direction of the first part, preferably by means of a sliding block or other guide means extending at least over a considerable length, for example, over 1 m or more. This gradual turning has the advantage that a high-quality edge between the two parts is obtained in a very repeatable manner. The process results in a rather straight break line of the DPL.
If desired, a post-treatment can be performed at the obtained edge after joining said two parts, at the height of the exterior side of the skirting board, where said two parts adjoin each other. This post-treatment may consist of colouring the edge with a colour, whether or not matching the top layer of both parts, removing an amount of material, or the like. Also, the post-treatment may consist of a sanding treatment or the removal of a larger material portion, for example, in order to form a bevel, after which, whether or not, a decorative layer can be provided on the treated surface, for example, in the form of a lacquer, varnish, impregnating agent, whether or not coloured, transfer print or other print.
According to a fifth aspect of the invention, it relates to a skirting board with as a characteristic that this skirting board has a laminated surface both at the front side and the upper side, whereby at the edge between the upper side and the front side, an amount of material has been removed, preferably in the form of a bevel, and whereby the obtained surface is provided with a decorative layer. According to this aspect, by a laminated surface each form of laminate can be understood. A general advantage thereof is that a proper edge finish can be obtained and in particular the occurrence of problems as a result of a difficult mutual adjoining of the laminated surfaces is excluded.
The decorative layer can be of any kind and may consist, for example, of a lacquer, a print, such as a transfer print, an impregnation, and so on.
It is noted that the surface for providing the decorative layer possibly can be subjected to a smoothing treatment, for example, by contacting the surface with a pressing-on element, such as a sliding block, pressure roller, or the like. More particularly, hereby use shall be made of a pressing-on element that is brought to a high temperature. This is particularly advantageous when applying MDF or HDF, as possibly protruding wood fibres then are flattened and are consolidated with the surface. Also, then possibly a kind of sealing can be created at the surface by the heating of the binding agent present in the MDF or HDF. In this manner, a very smooth surface is obtained, as a result of which also a smooth lacquer layer, transfer print or the like can be realized.
The technique, mentioned in the preceding paragraph, of smoothening also can be applied in general with laminated floor panels for treating a bevel or the like at such panels, for example, in order to subsequently provide a decorative layer on the treated surface. Here, too, this technique is particularly useful for floor panels whereby the aforementioned surface of the bevel or the like extends through MDF or HDF.
According to a sixth aspect, the invention relates to another particular form of embodiment of a floor panel. The characteristics and advantages hereof will become clear from the detailed description.

As represented in the form of embodiment of FIGS.1 to3, askirting board1, which is realized in accordance with the first aspect of the invention, consists of at least two structural parts2-3, afirst part2 forming at least a portion of thefront side4 of theskirting board1, and asecond part3 forming at least a portion of theupper side5 of theskirting board1, respectively, whereby both parts2-3 are formed of alaminate material6, which is formed by means of pressing power, with acore7 and a synthetic material-basedtop layer8 applied thereupon. As will become clear from the further description, the parts2-3 preferably are formed of a plate-shapedlaminate material6, whereby for forming the two parts2-3, one preferably has started from a similar or one and the same laminate material, which preferably shows one and the same pattern.
Thecore7 of the parts2-3 consists, for example, of MDF or HDF, whereas thetop layer8 preferably consists of one or more resin-impregnated layers, which are pressed upon the core. InFIG. 3, by way of example a detail is represented, in which thetop layer8 is composed of two layers, a so-calleddecor layer9, which preferably is provided with a print, and a so-calledoverlay10, respectively. Said print may represent a well-defined pattern, for example, a wood pattern, a stone pattern or the like, or may also consist of a monochrome print. The resins applied with these layers preferably are melamine resins, however, other possibilities are not excluded.
At the rear side, in this case, ofpart2, a so-calledbacking layer11 may be present.
Preferably, thelaminate material6 formed by thecore7, thetop layer8 and thepossible backing layer11, is realized as so-called DPL (Direct Pressure Laminate).
In the embodiment of FIGS.1 to3, theparts2 and3 are directly attached to each other by being glued together at their sides12-13 directed towards each other.
As clearly visible inFIGS. 2 and 3, said two parts2-3 adjoin each other with their outer sides14-15 at an angle, whereby thetop layers8 extend at an angle of 90 degrees up to theouter corner16 of theskirting board1.
In order to obtain that thetop layers8 neatly adjoin each other at the location of theouter corner16, saidparts2 and3 are realized such that, at least at the height of theouter corner16, adjoin each other in a mitre joint.
It is clear that theparts2 and3 may be realized in different shapes. For clarity's sake, in the following a number of variants is described with reference to FIGS.4 to16.
FIG. 4 shows an embodiment in which thesecond part3 is made triangular and fits into atriangular recess17 in the upper side of thefirst part2.
FIG. 5 shows an embodiment in which theupper side5 is realized inclined.
FIG. 6 shows an embodiment, in which thesecond part3 is trapezoid and fits into a similarly formedrecess18 in the upper side of thefirst part2.
It is noted that in the forms of embodiment of FIGS.1 to6, thesides12 and13, which are turned towards each other, have been created by a machining operation, as a consequence of which the parts2-3 can be realized very accurately and thus fit very precisely into each other, whereby the seam at theouter corner16 is not or almost not visible. However, this does not exclude other possibilities. So, inFIG. 7 an example is represented, whereby at thesecond part3 still a portion ofbacking layer11 is present and thus on that location no surface, obtained by a machining operation, is present, which, as discussed in the preamble, in certain cases may lead to a less precise embodiment.
Also, it is noted that, by using shapes that fit into each other, as is represented, for example, in the forms of embodiment ofFIGS. 4, 6 and7, automatically a mutually correct positioning is obtained when assembling theparts2 and3.
InFIG. 8, thesecond part3 protrudes towards the rear, such that a space or recedingportion20 is formed at therear side19 of theskirting board1, whereby the contact with the floor and/or wall is restricted when the skirting board is installed, such that a better adjoining can be guaranteed when the wall is irregularly formed at the bottom. As represented inFIG. 8, also one or more additional recesses may be formed in the rear side of thefirst part2, having the same purpose.
FIG. 9 shows a variant, whereby at the location of the corner edge a material portion has been removed, in this case in the shape of abevel22, upon which adecorative layer23 is applied, for example, according to any of the techniques mentioned in the introduction.
FIG. 10 represents an embodiment, whereby the parts2-3 are attached to a common support structure or connecting structure, in this case a commonbasic profile24. Hereby, the assembly of the components possibly may or may not be performed at the manufacturers'.
FIG. 11 shows a variant, whereby aninsert25 is provided between the parts2-3.
InFIGS. 12 and 13, a variant is represented, whereby theparts2 and3, at their sides directed towards each other, are provided withparts12A-13A and12B-13B that are situated crosswise in respect to each other, such that, during the assembly of theparts2 and3, more particularly, the gluing thereof, pressing forces can be exerted in two directions by means ofpressing elements26 and27, for example, pressing rollers. By this technique, a mutual shifting of theparts2 and3 during the pressing together can be completely excluded.
InFIGS. 14 and 15, two variants are represented, whereby one of the two parts, in this case,part3, has a bendable, more particularly elastically bendable,portion28, in such a manner that, when assembling theparts2 and3, and by bending thepart28, a tension force is realized, which contributes to a good closure of theparts2 and3 at the location of the top layers8. It is clear that hereby, preferably a space is present under theportion28, said space allowing such pressing that theportion28 can bend.
InFIG. 15, theparts2 and3 are provided with positioning means, which in their turn prevent a lateral shifting of theparts2 and3 in mutual respect, which positioning means in this case are formed by a tongue-shapedpart29 at thepart3 and agroove30 in thepart2.
InFIGS. 14 and 15 is also shown thatglue chambers31 for providing glue and/or collecting surplus glue can be provided at the necessary places.
FIG. 16 shows that at the rear side, not only aspace20 can be provided in order to reduce the contact of theskirting board1 with thefloor32 orwall33, but that also aprofile34 can be provided at the rear side, said profile being intended for cooperating with attachment accessories, in this case anattachment clip35 that is attached to thewall33.
In general, it is clear that, as a benefit of the invention, thetop layers8 of both parts2-3 can be optimally matched to each other and that it is even possible to let the possible patterns, which are represented on the top layers of theparts2 and3, fade into each other.
Because one can start from plate-shaped material, also the advantage is created that all special effects, which can be created when forming plate-shaped material, can be integrated in askirting board1 in an identical manner, with the intended particular effect both at thefront side4 and theupper side5 thereof.
InFIG. 17, an example of a particular effect is represented, whereby thetop layer8 of both parts2-3 is provided withimpressions36 in which acomponent37 is provided, for example, a colour component, by which, for example, as discussed in the introduction, lime-washed wood can be imitated.
It is clear that the use ofsuch impressions36 does not necessarily have to be combined with the use of a component that must be provided therein. Also,such impressions36 can solely be applied for imitating a relief, more particularly for imitating natural surfaces.
Said impressions may be in register with a pattern represented on the decor layer. This is particularly useful when imitating wood, however, is also not excluded for imitating other materials.
Also, it is possible to apply a coloured overlay, whereby particular effects, whether or not in combination with the use of impressions that may be coloured or not, can be realized.
FIG. 18 shows a floor covering system according to the invention, withfloor panels38 and askirting board1, which are matched to each other in that they are manufactured of a similar laminate material.
InFIG. 19, an embodiment of askirting board1 according to the invention is represented, whereby thetop layer8 of the two parts2-3 is provided with a tile pattern withjoints39 extending over thefront side4 andupper side5. InFIG. 19, those are wide joints obtained by means of a print. At the location of these joints, possibly an impression can be realized. Instead of joints obtained by means of a print, according to an alternative they can also be formed by material removal or recesses, whereby at the location thereof possibly a separate colouring or print is provided.
FIG. 20 schematically represents a possible form of embodiment of the method for manufacturing theskirting board1. In afirst step40, a plate-shapedsubstrate41, more particularly a material for forming thecore7, for example, an MDF or HDF plate, and a resin-impregnated printeddecor layer9, anoverlay10 and abacking layer11 are brought together. In asecond step42, this assembly of layers is pressed together in apress43 and consolidated by means of the resin. Hereby, simultaneously impressions can be formed in the upper side, for example, by means of anintermediate plate44 that is provided with arelief45. In this manner, a plate oflaminate material6 is obtained. Instep46, a lacquer47 or the like is rolled into the impressions. According to not-represented steps, then a forced drying of the lacquer47 can be provided, as well as a cleaning in order to remove a possibly remaining tinge of lacquer. Subsequently, thelaminate material6 is divided into strips, more particularly sawn tolaths48. By machining treatments, from those then theparts2 and3 can be formed, for example, by means of the necessary milling and/or planing treatments, after which those parts2-3 are connected to each other.
It is clear that different variants to this are possible. So, for example, it might be possible to provide the lacquer47 in the impressions only after theskirting board1 itself already has been manufactured.
It is noted that the laminate material also might be realized in a continuous press and that the possibly provided impressions also might be pressed into the surface in a separate press.
InFIG. 21, a particular method is represented in order to attach theparts2 and3 to each other. Hereby, laths or strips48 are connected, preferably glued, to each other in a tubular shape and with a mitre, such as shown centrally in the figure. The tubular structure offers the advantage that thelaths48 can be clamped in a stable manner during gluing. By subsequently cutting, more particularly, sawing the tubular piece according tolines49, fourskirting boards1 according to the invention are obtained.
InFIG. 22, a technique is represented whereby one starts from a lath orstrip50, which preferably is sawn off a plate, whereby in afirst step51, a profile is applied at both longitudinal edges52-53, after which thislath50, as represented instep54, is cut in longitudinal direction, in this case by means of asaw55. In this manner, twoparts2 and3 for forming theskirting board1 are obtained. In the representedstep56, another portion of thepart2 is removed, for example, milled away. Finally, theparts2 and3, as represented instep57, are assembled, after which, as represented instep58, they are attached to each other, in this case by means of glue. This technique offers the advantage that theedge52 can be formed while theportion3 still is present at thelath50, whereby a proper clamping and/or guiding during milling is possible. Also, bothedges52 and53 can be formed simultaneously by passingsuch lath60 in between two oppositely-situated milling cutters.
FIGS.23 to25 relate to a skirting board and a floor covering system, whereby both the first and second aspects of the invention are applied. To this aim, theskirting board1 consists ofshort pieces59, which are mounted successively one after the other, whereas eachpiece59 consists of at least two composedparts2 and3, as described above.
In the example, thepieces59 are provided with coupling means by which they can be coupled to each other in an indirect manner. In the represented example, these coupling means consist ofcoupling parts60 in the form of recesses, with which thepieces59 can be clamped onto acommon profile61 that, in its turn, is attached to the wall.
According to an important, although preferred characteristic of the second aspect, an imitation of a joint62 is present at the location of each transition between twopieces59. Possibly, additional joint imitations may be present between the extremities of eachpiece59. In the represented example, the imitations of thejoints62 are realized by means of removed material portions, in this case in the form ofbevels63, which preferably are provided with a decorative layer orcoating64, for example, by means of a lacquer, print or impregnation.
According to another important preferred characteristic, thepieces59 have a length that corresponds to the length of thefloor panels38 with which they are intended to be used, which is particularly useful for floor panels imitating stone tiles. In this manner, it becomes possible to realizeskirting boards1, whereby thejoints62 are situated precisely opposite to thejoints65 of the tile-shapedfloor panels38, as is illustrated in detail inFIGS. 24 and 25.
InFIGS. 26 and 27, two variants are represented, whereby, instead of using indirect coupling means, use is made of direct coupling means66 in order to interconnect thepieces59, which coupling means66 allow for a connection between the narrow sides of thepieces59, more particularly between the extremities oredge areas67 and68.
The coupling means66 consist offirst coupling parts69, substantially in the form of atongue70 and agroove71, which realize at least a well-defined locking in a direction R1 perpendicularly to the plane of theskirting board1, andsecond coupling parts72, which realize at least a well-defined locking in a direction R2 according to the length of theskirting board1, whereby thesecond coupling parts72 at least comprise, on the one hand, apart73 which can be pressed down in an elastic manner, crosswise to the plane of theskirting board1, whether or not perpendicularly thereto, whichpart73 is situated at one of the edge areas67-68, preferably at theedge area68 at which thetongue70 is present, and, on the other hand, apart74 cooperating therewith, saidpart74 preferably not being able to be pressed down or being less compressible, at the other edge area, whereby these twocoupling parts72 are situated in a zone behind the tip of thetongue70, and even better entirely or almost entirely behind the zone T taken by theactual tongue70. By “behind the tip or zone T” is meant that thecoupling parts72, and in the first place the locking contact surfaces of these coupling parts, are situated more towards the inside at those respective parts. In this case, the zone T must be considered as the distance with which the tongue is sitting behind the shortest groove-bordering lip.
Thepart74, which cooperates with thepart73 as a hook-shaped part, preferably is situated on a protrudinglip76.
FIG. 26 shows an embodiment in one piece, whereby thepart73 that can be pressed down is formed by a portion of an elasticallybendable lip77, whereby the impression thus is the consequence of bending, whereasFIG. 27 shows a variant in which thecompressible part73 consists of an elastically compressible material, such as a relatively stiff rubber strip, whereby the impression thus is the result of a material compression. It is clear that thelip77 also may extend in other directions. As represented, in both cases thepart73 is situated at the rear side of the tongue, in other words, the side which is directed towards the wall. According to a variant, thepart73 might also be situated at the front side.
In a laminate structure with pressed layers of resin, the layer that is situated against thelip76 preferably extends up to or into the proximity of thecoupling part74 in order to thereby maximally maintain the rigidity of thelip76.
As schematically indicated by arrows, the coupling means hereby preferably are realized such that thepieces59 can be engaged into each other by shifting and/or turning. Hereby, turning around the front edge is the most practical technique, however, shifting may be necessary ifpieces59 have to be installed against a wall, at places that are difficult to reach. Hereby, the coupling can be realized without play.
The coupling means ofFIGS. 26 and 27 allow to smoothly shift and turn thepieces59 into each other. In that, at least in the represented form of embodiment, thepart73 can be pressed down almost separately from the remaining material parts, these remaining parts are stressed little or not at all.
It is noted that the coupling means described above by means ofFIGS. 26 and 27 for connecting thepieces59 of a skirting board can be applied, according to the invention, in a similar manner for connecting floor panels, more particularly laminated floor panels, whether this takes place in combination with the application of a skirting board according to the invention or not. According to this sixth aspect of the invention, then the wall in the drawings must be omitted, whereby the front side of thepieces59 then must be seen as the upper side of such floor panel. Such floor panels then can be laid in a floating manner, without connection to the subfloor. Preferably, such floor panels are rectangular and are provided on four sides, in other words, edges, with coupling means realizing a vertical and horizontal locking, whereby at two opposite sides, coupling means as described above are provided, whereas at the other two sides coupling means may be provided which are realized in another manner; preferably, however, not necessarily, coupling means allowing exclusively a coupling by turning-in and not by shifting. In the case of floor panels, the coupling parts preferably are realized from MDF, and even better, HDF, preferably in one piece out of the substrate of the floor panel.
In front view and a rear view, respectively,FIGS. 28 and 29 show a further variant of a piece of skirtingboard59 for realizing askirting board1 according to the invention, whereas FIGS.30 to33 represent how several ofsuch pieces59 are mounted.
A first particularity of the form of embodiment represented in FIGS.28 to33 consists in that thepieces59 are provided with coupling means66, with which thepieces59, at their extremity, can be directly coupled to each other. More particularly, thepieces59, at their small faces, comprise coupling means extending parallel to thefront side4 as well as coupling means extending parallel to theupper side5, differently designated by66A and66B. In the represented example, these coupling means66A-66B are realized in a manner comparable to that ofFIG. 26 and to this aim each substantially consist offirst coupling parts69 in the form of a tongue and a groove realizing at least a well-defined locking in a direction perpendicular to the side, thefront side4 or theupper side5, respectively, of thepiece59 along which the coupling means66A-66B are provided, andsecond coupling parts72 realizing at least a well-defined locking in the longitudinal direction of theskirting board1.
It is noted that by applying both coupling means66A as66B, these also function as positioning means providing in that thesuccessive pieces59 during the mounting thereof are automatically aligned in mutual respect both in height and in depth. It is clear that according to not-represented variants, also other positioning means can be applied in order to obtain a partial or complete alignment of thepieces59 in respect to each other.
FIGS.30 to32 show that the coupling means66A and66B preferably are similar and even identical to each other. This offers the advantage that, in the case that thepieces59 are manufactured of twostructural parts2 and3, these parts can be manufactured starting from the same piece of material, more particular laminate material, which prior thereto has been provided with the respective coupling means at two opposite sides. By composing theparts2 and3 manufactured therefrom in a mitre joint, then automatically a design is obtained as illustrated in FIGS.28 to33.
The coupling means66A-66B represented inFIGS. 31 and 32 are of such a type that therewith a coupling by means of a turning movement W, as well as a shifting movement S can be realized, whereby at least in the latter case, then a locking by means of a so-called snap action is taking place.
The coupling of the pieces of skirtingboard59 then may take place as illustrated inFIG. 31, in which theleft piece59 already is mounted against thewall33 and thepiece59 shown at the right hand side in the figure first is presented inclined with one extremity against the already mounted piece, as illustrated in dashedline78. By now turning thenew piece59 to be mounted against thewall33 by means of the turning movement W, the coupling means66A, as indicated inFIG. 31, engage each other. Thereby, automatically also an engagement at the coupling means66B is created, whereby, seen purely in the vertical cross-section ofFIG. 32, exclusively a lateral shifting into each other of the respective coupling means is taking place.
However, within the scope of the invention, it is not excluded that the coupling means66A and66B differ from each other. So, for example, may the coupling means66A be of the type that exclusively allows to make a connection by means of a turning movement, whereas the coupling means66B may be of the type that exclusively allows a connection by means of a shifting movement.
A second particularity of the form of embodiment represented in FIGS.28 to33 consists in that thesuccessive pieces59 are provided with attachment means, which are constructed such that they are seated blindly by mounting the next piece of skirtingboard59. In the represented example, these attachment means are formed by a strip oflath79 provided against the rear side of eachpiece59, which stroke orlath79 facilitates the attachment of eachrespective piece59 at the wall or at another common support structure, possibly by means of screws, glue, or the like. The strip oflath79 is provided such that it extends with one extremity beyond the remainder of the piece of skirtingboard59 and in this manner forms an attachment part, more particularly anattachment lip80. As represented, this attachment part preferably is situated at the extremity where the coupling means66A-66Bshow coupling parts69 in the form of a groove. The thickness of thestrip79 preferably is such that theskirting board1 in mounted position fits in a sufficient manner with itsupper side5 against thewall33, as schematically represented inFIG. 33.
The use of the aforementioned attachment means can simply be derived from FIGS.30 to33 and substantially consists in that each piece of skirtingboard59, after being coupled with one extremity to a precedingpiece59, is attached at the other extremity against thewall33, by providing anelement81, such as a screw, nail, or the like through theattachment lip80 up into thewall33. It is clear that, when attaching apiece59, each time theattachment lip80 of the preceding59 is put out of sight.
It is clear that the use of a combination of, on the one hand, mechanical coupling means allowing a locking between thesuccessive pieces59 with, on the other hand, attachment means that are provided such that they are put out of sight when each followingpiece59 is mounted, allows an advantageous and smooth mounting of the skirting board, regardless of the nature of these coupling means and attachment means.
It is also clear that according to variants, also other forms of embodiments of attachment means are possible. So, for example, may the lip B2 represented inFIG. 31 be realized rather long, as a consequence of which this lip can be used as an attachment means, on account of the fact that then also a nail, screw or the like can be applied therethrough.
According to a variant, also astrip79 can be provided against the rear side of theskirting board1, which strip79 is provided with a special profile and allows to connect theskirting board1 with accessories provided against awall33, for example, to fasten it on attachment clips.
FIG. 34 illustrates a method for manufacturing askirting board1 according to the aforementioned fourth aspect of the invention, whereby here, both a short piece of skirtingboard59, for example, with the typical length of a floor tile, for example, less than 70 cm, or of a typical floor panel, as a longer piece of skirtingboard1, for example, in the order of magnitude of two meters or more, may be concerned. In this method, one starts from laths or strips of alaminate material6 consisting of acore7 and atop layer8, specifically of the DPL type. As can be seen inFIG. 34, amaterial part83 is removed in the longitudinal direction of this lath, whereby, as represented in the enlargement ofFIG. 35, preferably also a weakenedzone84 is formed, whereby material is removed, in this example partially up into thetop layer8. Hereby, two parts are created, in the represented example twostructural parts2 and3, which are only connected to each other by a portion of thetop layer8. Then, theskirting board1 can simply be realized by turning theparts2 and3 around the thus created folding or breakingline85 towards each other and joining them, whereby they are attached to each other, for example, by means of glue, and in this manner a condition is obtained as illustrated inFIG. 36.
It is underlined that the fourth aspect of the invention is specifically connected to the use of atop layer8 in the form of so-called “DPL”, which then, as known, is formed of one or a small number of resin-impregnated carrier sheets, amongst which mostly a decor layer, which sheets are directly pressed onto the underlying substrate, in this case, the material of thecore7. InFIG. 35, schematically atop layer8 consisting of DPL is represented, with only a single printed carrier sheet87 impregnated withresin86, said sheet then forming theaforementioned decor layer9. It is noted thatFIG. 35 is highly schematised and thetop layer8 is represented with exaggerated thickness. In reality, with DPL a layer in the order of magnitude of 0.2 mm or smaller is concerned. Of course, the invention according to the fourth aspect also relates to applications in which DPL with more than one support sheet is applied, for example, DPL formed of the combination of a decor layer and a so-called overlay.
Further, it is noted that the inventors surprisingly found out that, in case a weakenedzone84 is formed whereby material is removed partially up into the “DPL”top layer8, theskirting board1, after joining the two obtainedparts2 and3, has an edge that is of a strikingly high quality, whereby little or no post-treatment is necessary. With thin and brittletop layers8, such as the one of “DPL”, it was always assumed that forming a weakenedzone84 extending at least partially into thetop layer8 and/or accurately breaking and/or accurately folding it, was impossible.
Due to the fact that aDPL top layer8 has a very small thickness, the advantage is obtained that when turning along the folding or breakingline85, already a relatively proper finished corner is obtained affording little or no finishing treatment, which is even promoted by using, as aforementioned, a weakenedzone84 partially extending up into thetop layer8.
The inventors also found that in case the weakenedzone84 is realized less deep and below this weakened zone84 a very small amount of material of thecore7 is left at the place where theparts2 and3 must be folded and/or broken, still a qualitatively rather good corner finish is obtained, in particular with acore7 of MDF or HDF. Preferably, here an amount of material with a thickness of less than 0.5 mm is concerned.
According to a not-represented variant of the invention, at the location of the second part all material except theDPL top layer8 is removed, whereby the second part then no longer is a structural part.
FIG. 36 represents the obtained product. As represented in the figure, possible post-treatments of the edge may consist of the removal of a small material portion, for example, by means of a sanding treatment, for example, as schematically represented, by moving along the edge with a sandingelement88, whether or not followed by the provision of adecorative layer23 on the obtained surface, as represented, for example, inFIG. 37, by means of a colouring treatment, in this case by means of apen89 or the like. Of course, any other colouring method is possible. Nothing impairs that the colouring treatment takes place without a preceding sanding treatment, whereby the colouring then is intended for masking possible discolorations due to the bending and/or breaking of thetop layer8 and/or to grinning-through of underlying material.
Instead of moving along the edge with a sandingelement88, the edge also can be brought into contact with a preferably heated pressing-down element, such as a sliding block or roller, such that the possibly coarse edge is smoothened. Of course, this may also take place in combination with a sanding treatment.
FIG. 38 shows that a material portion can be removed on the edge, for example, for forming a bevel, and whereby the obtained surface is provided with adecorative layer23.
It is noted that the technique ofFIG. 38, according to which a material portion is removed and adecorative layer23 is provided, also is advantageous for any other type ofskirting board1, whereby a laminated surface is present both at thefront side4 and theupper side5. By means of the aforementioned technique, in fact the advantage is created that a proper edge finish can be obtained and the occurrence of problems due to a difficult mutual adjoining of the laminated surfaces is excluded. According to a fifth aspect, the invention thus in general also relates to skirting boards with a laminated surface, with as a characteristic that a material portion is removed at their edge and adecorative layer23 is provided at their surface.
For clarity's sake,FIG. 39 shows another possible form of embodiment of this fifth aspect. Theskirting board1 has a laminated surface both at itsfront side4 and at itsupper side5. In this example, the laminated surface at thefront side4 is formed by DPL or HPL, whereas the laminated surface at theupper side5 is formed by a glued-onlaminate ribbon90. In that use is made of a bevel and adecorative layer23, which are applied after the application of thelaminate ribbon90, no high precision is necessary when applying thelaminate ribbon90 itself.
In general, it is noted that the invention is intended in particular for being used with skirting boards with a laminated surface of the type formed by thermo-hardening laminate, for example, DPL on the basis of a thermo-hardening resin, such as thermo-hardening melamine resin. However, this does not imply an exclusion of other applications.
The present invention is in no way limited to the forms of embodiment described by way of example and represented in the figures, however, such skirting board, such floor covering system, said floor panels and said methods for manufacturing a skirting board can be realized according to different variants, without exceeding the scope of the invention.
So, for example, the aforementioned finishing treatments, such as the application of a component in the impressions, the glossing of the laminate surface, must not necessarily take place prior to forming theparts2 and3 or prior to the application of the laminate film. This may also take place after the assembly of theparts2 and3 or after the application of the laminate film at the remaining parts of the skirting board.
In the previous description the term “laminate material” always refers to board shaped material having a core and a top layer. The core may consist of one or more parts or layers. The term “laminate plate” refers to the basic board before being cut into pieces. The term “laminated” means that the related surface is provided of a laminate of any type. The term “laminate film” refers to a thin foil of any kind of laminate, which is produced as a separate layer. A “laminate ribbon” is a strip-like portion of a laminate film.
The aforementioned “joints” should generally be understood as being an imitation of “grouts”, although they do not always need to imitate cement.
The thickness of thelaminate material6 will generally be 7 to 9 mm, although other possibilities are not excluded.
