CROSS-REFERENCE TO RELATED APPLICATION This application claims priority under 35 U.S.C. §119 of French Patent Application No. 05.12993, filed on Dec. 20, 2005, the disclosure of which is hereby incorporated by reference thereto in its entirety.
BACKGROUND OF THE INVENTION 1. Field of the Invention
The invention relates to a device for receiving a foot or a boot onto a sports apparatus, and more specifically to a device provided with a support element located between the sole of the foot or the boot sole and the apparatus.
More specifically, the invention relates to devices of the aforementioned type used for the practice of snowboarding, snow or water skiing, snowshoeing, roller-skating, or the like.
2. Description of Background and Relevant Information
Generally speaking, the support element for the rider during use of an apparatus such as any of those mentioned above, affects the steering of the apparatus, because the support element transmits steering forces/impulses or sensory information between the foot or the boot and the apparatus. The support element, therefore, must have specific characteristics.
For example, due to its size or location, the support element must render the receiving device compatible with a user's foot or boot. In particular, the device and its support element must be adapted to the size of the foot or the boot.
The support element can also be provided to have a customized portion to carry out a particular function. This portion must act in a specific area of the foot or boot. Therefore, the support element must be arranged on the receiving device so that the customized portion can fulfill its function.
In the field of snowboarding, it is known to adjust the position of the support element of a receiving device, i.e., to adjust the position of the boot support element of the binding. More particularly, the support element is longitudinally positioned without protruding or being set back with respect to the sole of the boot. The adjustability enables the size of the boot to be taken into account. If the support element has a customized portion, such as a wedge, pad, or other expedient to amplify steering impulses, it is important that it be positioned in the area of one end of the boot. The wedge is then located directly above the toe or directly above the area of the heel, i.e., such as a toe pad or a heel pad. Two such support members can be provided.
The prior art has proposed solutions to adapt a receiving device, or binding, to the size of the foot or boot and/or to adjust the position of a support element of the device/binding.
For example, U.S. Pat. No. 6,113,114 discloses a receiving device, i.e., a snowboard binding, more particularly, having a baseplate and a support element associated together to receive a foot or a boot. Adjustability is provided in the longitudinal position of the support element with respect to the baseplate. The particular means disclosed therefor includes a specific surface provided on the support element, a complementary surface, provided on the baseplate, open cavities provided in the support element, on the one hand, and in the baseplate, on the other hand, as well as screws which extend through the support element and the baseplate to be housed in respective nuts.
A drawback of the receiving device according to U.S. Pat. No. 6,113,114 lies in its complex structure. Indeed, its constituent parts are numerous and some of them are complicated to manufacture.
Furthermore, the device according to U.S. Pat. No. 6,113,114 requires a time-consuming and difficult adjustment. Indeed, at least one tool is required to turn the screw. Another tool is usually required to immobilize the nut while the screw is being turned. Furthermore, the tools are applied on opposite surfaces of the baseplate. It is therefore necessary for the device not only to have been first detached from the board on which it is used, but also to be held in order to use the tools
SUMMARY OF THE INVENTION The invention simplifies the structure and the manufacture of a receiving device having a support element, in the case in which it is required to adapt the device to the size of the shoe or foot of the user.
The invention also simplifies the adjustment of the support element position with respect to other portions of the device.
In addition, the invention facilitates the positioning of a customized portion of the support element in a specific area of the device.
To this end, the invention proposes a device for receiving a foot or a boot on a sports apparatus, the device including a support element intended to be located between the sole of the foot or the boot and the apparatus.
The support element of the invention includes a first portion, a second portion, and an arrangement to adjust the position of the first portion with respect to the second portion.
The adjustment arrangement enables the adjustment of the position of one of the support element portions with respect to the other. This makes it possible to vary the configuration of the support element in order to adapt it to a dimension or to a desired function. For example, the support element can be lengthened or shortened according to the size of the boot or foot, or one portion can be arranged in a selected location. As a result, it is not necessary to provide a complicated connection between a baseplate and a support portion. A resulting advantage is simplification in the structure and the manufacture of the receiving device. Another advantage is a simplified adjustment of the position of a support element portion, especially due to its accessibility.
In a particular embodiment, the invention is directed to a snowboard having a baseplate, a pair of longitudinally extending flanges to demarcate a zone for receiving a boot, and a highback articulated relative to the baseplate for supporting the rear of the rider's lower leg. The support element includes an arrangement for connection to the baseplate, as well as an arrangement for adjusting the relative positions of first and second portions of the support plate, both without the need of a tool and both without the need of screws or other threaded fasteners.

DETAILED DESCRIPTION OF THE INVENTION Although the embodiments of the invention described hereinafter are more particularly related to the field of snowboarding, it is to be understood that they also apply to other fields, such as those mentioned above.
The first embodiment of the invention is shown in FIGS.1 to7.
As shown in the exploded perspective view ofFIG. 1, a receivingdevice1 temporarily receives a boot (not shown) on aboard2. The receivingdevice1 is part of a snowboard binding.
In a known manner, the receivingdevice1 includes a baseplate3, which extends longitudinally between arear end4 and afront end5.
The baseplate3 includes a receivingsurface6 adapted to face the sole of the boot, and a supportingsurface7 adapted to face theboard2 and to be supported thereon.
The baseplate3 is secured to theboard2 by means of a mounting assembly consisting of a plurality of parts. Such plurality includes, e.g., adisk10 and a plurality ofscrews11, the disk being secured to theboard2 by means thescrews11, as shown. Such a mounting assembly can include additional parts within the scope of the invention and can take the forms, e.g., of either of U.S. Pat. No. 6,068,283 and U.S. Pat. No. 6,676,152, both commonly owned herewith, the disclosures of which are hereby incorporated by reference thereto in their entireties. As shown inFIGS. 1 and 2, thedisk10 is provided withslots12 through which thescrews11 extend, the screws being threaded into the board (or into complementary-threaded elements embedded in the board). For example, fourslots12 are provided for fourscrews11, the screws being arranged at the four corners of a square, for example. Theslots12 are parallel to one another to allow for a translational adjustment of the position of thedisk10 with respect to theboard2.
A different number of screws and slots can be provided within the scope of the invention. For example, three screws could be arranged at the vertices of an equilateral triangle and three slots could be provided.
Mere holes arranged in the disk are sufficient for the providing the retention function for the baseplate, but the advantage of slots, as shown, is that they offer the possibility of adjusting the position of the baseplate.
Other mechanisms for retaining the baseplate on the board could be provided, as alternatives to those mentioned.
The baseplate3 is laterally bordered by alateral flange13 and amedial flange14. Each of theflanges13,14 forms a lateral portion or a medial portion, respectively, of thedevice1 to demarcate azone15 for receiving the boot. Once the boot is in position on thedevice1, theflanges13,14 extend along respective opposite sides of the sole of the boot. Alternatively, the lateral and medial portions of the baseplate could be formed by something other than theflanges13,14. For example, mere lateral and medial abutments, perhaps formed in one piece with the baseplate, could be used.
In a particular embodiment, the baseplate3 and theflanges13,14 are made as a one-piece, or unitary, element, made of synthetic material, for example. However, the flanges could be elements separate from the baseplate and affixed to the baseplate by any of several alternative means, such as glue, welds, screws, nesting, or by other expedients or methods.
Thedevice1 also includes arear support element20, or highback, that enables the user to be supported rearwardly at the lower leg and to apply rearward pressure thereto.
According to the first embodiment of the invention, therear support element20 is associated with theflanges13,14 by means of anarticulation21 or pivot connection, for example. Thearticulation21 is oriented substantially along atransverse axis22 of thedevice1. Thearticulation21 can include any component, such as a screw, a rivet, a washer, a screw nut, a swivel pin, or the like.
Thearticulation21 enables therear support element20 to be moved toward the baseplate3. A resulting advantage is that storage of the binding is thereby facilitated.
Therear support element20 could also be directly associated with the baseplate3. Therear support element20 could also be directly affixed to the apparatus directly, in this case, to theboard2. It only has to be positioned on the apparatus to allow the application of rear support forces with the lower leg.
According to the first embodiment of the invention, anabutment23 limits the rearward rotation of therear support element20.
In a non-limiting manner, theabutment23 includes acable24 that extends around therear support element20.
Any other structure for providing an abutment for limiting rearward movement of therear support element20 could be used. For example, the abutment could include a connecting arch, such as a rigid arch, between theflanges13,14 in order to oppose a rearward movement of the rear support element.
Two linkages are also provided to removably retain the boot on the baseplate3, between theflanges13,14 in the receivingzone15.
Afirst linkage30, or strap, is located at the front, in the area of the metatarsophalangeal articulation zone of the foot when the foot is being retained on the device. Asecond linkage31, or strap, is located towards the back, in the area of the instep when the foot is retained.
Each of thelinkages30,31 extends transversely between theflanges13,14 and, in the exemplary illustrated embodiment, are connected to theflanges13,14.
A different number of linkages could be provided in alternative embodiments within the scope of the invention.
The receivingdevice1 also includes asupport element32, which is provided to be arranged between the sole of the foot or the boot and the sports apparatus, or snowboard, as can be seen inFIGS. 1 and 2.
According to the first embodiment of the invention, thesupport element32 is adapted to cover the entire baseplate3 and to extend in the entire receivingzone15. To do so, thesupport element32 extends lengthwise between arear end33 and afront end34, widthwise between alateral edge35 and amedial edge36, and thicknesswise between a receivingsurface37 and asupport surface38. The receivingsurface37 is adapted to receive a foot or a boot, thesupport surface38 being adapted to face the baseplate3 and to take support on the latter and on theboard2, directly or indirectly.
Thesupport element32 thus constitutes an interface between almost the entirety of the sole of the boot and the baseplate3. A resulting advantage is that it provides the boot or the foot with continuous stability, i.e., stability along the entire length of the boot or foot.
Thesupport element32 also covers thedisk10. This protects thedisk10, thescrews11 and theslots12 from damage. For example, thesupport element32 prevents theslots12 from being partially or entirely blocked by foreign matter. In the case of a snowboard, especially, thesupport element32 protects from snow, ice, and miscellaneous debris, such as dirt, gravel, etc.
According to the invention, as seen in FIGS.1 to7, thesupport element32 includes afirst portion51, asecond portion52, and an arrangement for adjusting the position of thefirst portion51 with respect to thesecond portion52.
The adjustment arrangement allows the position, such as the longitudinal position, of one of theportions51,52 to be adjusted with respect to the other. Thesupport32 therefore has a variable configuration. Thus, it is possible to adapt the device to a foot or a boot as a function of at least certain characteristics, such as the length, or even the width or thickness, without modifying other parameters on the device.
According to the first embodiment of the invention, thefirst portion51 of thesupport element32 includes afront piece53. Thefront piece53 includes arear end54 and afront end55, alateral edge56 and amedial edge57, as well as a receivingsurface58 and asupport surface59. The receivingsurface58 of thefront piece53 forms a subdivision of the receivingsurface37 of thesupport element32. Thefront end55 of thefront piece53 is merged with, i.e., is identical with, thefront end34 of thesupport element32.
Thesecond portion52 of thesupport element32 includes arear piece65 and abridge66. Therear piece65 of the second portion of the support element and thebridge66 are made as a one-piece, or unitary, member. Alternatively, therear piece65 and thebridge66 could be made as an assembly of two or more members, connected together by means of any technique known to those having ordinary skill in the art.
Thesecond portion52 of thesupport element32 includes arear end67 and afront end68, alateral edge69 and amedial edge70, as well as a receivingsurface71 and asupport surface72. The receiving surface of thesecond portion52, which extends along therear piece65 and thebridge66, is a subdivision of the receivingsurface37 of thesupport element32. Therear end67 of therear piece65 is the same as the rear end3 of thesupport element32.
The arrangement for adjusting the relative positions of thefirst portion51 and thesecond portion52 functions according to the male/female assembly principle. For this purpose, the adjustment arrangement includes a mechanism for guiding thefirst portion51 with respect to thesecond portion52. The guiding mechanism of the adjustment arrangement includes aprojection80, or tongue, extending from thebridge66, as well as ahousing81 arranged in thefront piece53 of thesupport element32. Theprojection80 and thehousing81 have complementary shapes, respectively, to allow for the sliding of one within the other. Consequently, thefirst portion51 and thesecond portion52 can move toward or away from one another, as is further described below.
Theprojection80 extends longitudinally from thefront end68. Theprojection80, thebridge66, and therear piece65 form a unitary element, i.e., a one-piece element. Theprojection80 is shown to have a U-shaped transverse cross section, but any other cross-sectional shape can be used within the scope of the invention.
Thehousing81 is arranged on the side of thesupport surface59 of thefront piece53. Thehousing81 is demarcated by acontoured block82, the shape of which, a * U-shape in this case, is complementary to that of theprojection80. Thehousing81 opens out toward therear end54 of thefront piece53. The contouredblock82 and thefront piece53 form a unitary, one-piece element.
As mentioned above, theprojection80 and thehousing81 contribute to the longitudinal guiding of thefirst portion51 of thesupport element32 with respect to thesecond portion52.
The adjustment arrangement includes a mechanism for immobilizing thefirst portion51 with respect to thesecond portion52. Such immobilizing mechanism includes, for example, recesses83 that are provided in thebridge66 as well aspins84 extending from thesupport surface59 of thefront piece53. Therecesses83 are adapted to cooperate with thepins84, as explained below.
Therecesses83 are arranged in transverse rows in the vicinity of thefront end68 of thesecond portion52.
For example, two rows of four recesses are provided in the illustrated exemplary embodiment. However, alternatively, a different number of rows, particularly more than two, could be provided. Each row includes fourrecesses83, for example, although such number could also vary to be less than or greater than four. In fact, at least one recess is needed per transverse section.
In correlation with therecesses83, one or several transverse rows ofpins84 are provided in the vicinity of the rear end of thefront piece53. The space between thepins84 allows for their insertion into therecesses83.
In a non-limiting manner, therecesses83 extend through thebridge66 and thepins84 form a unitary, one-piece, element with thefront piece53. Alternative constructions are also possible within the scope of the invention.
The positioning of thefirst portion51 with respect to the second portion.52 is explained more specifically by with reference toFIGS. 6 and 7.
Theportions51,52 are arranged so as to form an angle with respect to one another. Theprojection80 is then inserted in thehousing81. Finally, the portions are displaced so that theprojection80 slides inside the housing until a row ofpins84 faces a row ofrecesses83. The portions are then arranged so as to be parallel to one another, with the pins being housed in the recesses.
Thepins84 each have a shape enabling them to be retained in therecesses83. They can be retained by being force-fitted therein, by having one-way ratchet-like structures, or the like. Any shape of pin can be used for this purpose, such as a catch having a narrow base and an enlarged split, or non-split head.
The adjustment of the position of thefirst portion51 with respect to thesecond portion52 can be carried out easily, i.e., manually without any tool, i.e., without the need for a screwdriver or wrench, for example.
Further, for the sake of simplicity, an arrangement to assemble thesupport element32 to the baseplate3 without the need for any tool has also been provided. Thesupport element32 can therefore be easily and quickly assembled to or separated from the baseplate3. Ease of care and quick access to the adjustment screws11 of thedisk10 are some of the resulting advantages.
As can be understood with reference to FIGS.1 to7, the assembly arrangement includes female and male elements arranged so as to removably retain thesupport element32 on the baseplate3.
The female elements are in the form of slots oropenings94,95,96,97 which extend thicknesswise through thesupport element32. Tworear slots94,95 are located substantially at the junction of therear piece65 with thebridge66. Twofront slots96,97 are located substantially at the front of thebridge66.
The male elements are shown in the illustrated exemplary embodiment aslugs98,99,100,101 arranged on the baseplate3, thelugs98,99,100,101 being provided to be nested in theslots94,95,96,97 of thesupport element32. For example, tworear lugs98,99 project from the baseplate3, in the area of therear end4. Twofront lugs100,101 project from the baseplate3, in the area of thefront end5.
A reverse arrangement is possible within the scope of the invention. The support element could include lugs and the baseplate can have notches to receive the lugs. Similarly, the number of slots, notches, and lugs on each side can vary within the scope of the invention.
According to the first embodiment of the invention, the receivingsurface37 of thesupport element32 is a substantially smooth surface, which makes cleaning easier. It can also be provided with surface that is not smooth or that is designed to increase the friction coefficient with the boot.
Complementarily, therear piece65 and thefront piece53 have arear cover110 and a front cover111, respectively, each opened on the side of thesupport surface38. Arear cushion112 and afront cushion113 are housed within thecovers110,111 of the front andrear pieces65,53, respectively. In the exemplary embodiment illustrated, each cushion,112,113 projects with respect to thecover110,111 so as to be in direct contact with theboard2. Thecushions112,113 dampen the impacts received from the board or impulses transmitted while steering theboard2. Eachcushion112,113, can be made of, or include, a flexible and/or elastic synthetic material, such as polyurethane or polyethylene foam, or any similar material suitable for the purpose provided by the cushions.
The second embodiment of the invention is presented hereinafter with reference to FIGS.8 to11. For simplification purposes, only the specific characteristics of this embodiment are shown, although the structure and function of the second embodiment can be understood with the foregoing description as a preface.
The second embodiment, like the first, also includes a receivingdevice131 having abaseplate132, adisk133, alateral flange134, amedial flange135, arear support element136, afirst linkage137, and asecond linkage138.
Thedevice131 also features afirst support element151, or front support element, located toward the front of thebaseplate132. By analogy, thedevice131 also has asecond support element152, or rear support element, located toward the rear of thebaseplate132. None of thesupport elements151,152 cover the central portion of the baseplate located between the front and the rear, or thedisk133. The disk remains visible and accessible when the support elements are positioned on the device.
According to the invention, at least one of thesupport elements151,152 has afirst portion161, asecond portion162, and an arrangement for adjusting the position of thefirst portion161 with respect to thesecond portion162.
In this case, it is thefront support element151 that has two portions. However, it could be for therear support element152 instead, or both.
The adjustment arrangement has, for example, complementary shapes that are arranged on theportions161,162 in order to adjust the relative positions of such portions.
Thefirst portion161 thus presentstransverse notches163 arranged along transverse directions. Thesecond portion162 hastransverse extensions164, arranged along transverse directions and adapted to be nested in thenotches163 of the first portion.
Two rows of notches and one row of extensions have been provided. Two relative positions of theportions161,162 are thus provided. Once again, the configuration of thesupport element151 can vary within the scope of the invention. This makes it possible, for example, to adjust thedevice131 to the size of the user's foot or boot.
Other structures for the adjustment arrangement can also be suitable within the scope of the invention. It is possible, for example, to use a lug, a housing, recesses, and pins as in the first embodiment.
The invention can be made of materials and with implementation techniques known to one having ordinary skill in the art.
The invention is not limited to the particular details of the embodiments described above, but rather encompasses all of the technical equivalents which can be included within the scope of the claims that follow.
For example, a support element can be structured so that its width can vary.
Further, a first portion can be provided to include a front piece and a bridge, and a second portion to include a rear piece. In such a case, the arrangement for adjusting the relative position of the portions is arranged at the rear of the disk.
In addition, although more than two rows of recesses and/or pins, such as rows ofrecesses83 and/or pins84, can be provided for increasing the number of discrete adjustments in the relative positioning of the front and rear pieces of the support element, the spacing between such rows can be varied, i.e., increased or decreased, although the spacing chosen can be any particular distance. In this regard, within the scope of the invention the distance between rows of pins and/or recesses can be equal to the difference between one or more standard shoe sizes, i.e., such as the difference between one or more successive sizes of shoes and boots marketed in the United States, such as U.S. sizes, U.K. sizes, European sizes, Mondopoint (mm) or Centimeter (cm) sizes. As an example, such a distance could be equal to or greater than the difference between a men'sU.S. size 10 shoe and a men's U.S. size 10½ shoe or equal to or greater than the difference between a men sU.S. size 10 shoe and a men'sU.S. size 11 shoe. Alternatively, the spacing between rows of recesses and/or pins can be 0.5 cm, 1.0 cm, or 2.0 cm, or the spacing could be even greater, whereby in a first position, the length of the support plate accommodates a first range of shoe sizes and, in a second adjusted position, the length of the support plate accommodates a second range of shoe sizes.
Still further, although thepins84 can have a particular shape so that they can be retained within their respective recessed83, it is also within the scope of the invention for thepins84 to have a shape, such as a purely cylindrical shape, i.e., non-headed, so that they are merely positioned within therecesses83, such as circular holes, so that they are retained horizontally, but so that they do not provide vertical retention. In such an embodiment, the vertical retention of the first andsecond portions51,52 of the support element can be provided by theprojection80 and block82 and/or other structures.
