Description

The shoe-pad that is used for shoes

The present invention relates to a kind of shoe-pad (inner sole), flat shoe-pad substrate with an elastic foam material, this substrate is corresponding with the profile of footwear, and corresponding in the above plantar reflex area place comprise a plurality of integrated be the protuberance of elastic foam material equally.

The end in these footwear that term shoe-pad is understood that on the one hand with sole is fixedlyed connected, also can be regarded as loosely and is placed on shoe-pad on the sole, and it also is known as plug-in type shoe-pad (inlay sole).Shoe-pad is the more wide in range term that can be regarded as the interior end (insoles) of footwear and cover type sole (cover soles).

The known shoe-pad that is provided with the suitable protuberance that is used for reflection area massage changes at most in various embodiments.Such shoe-pad majority all is provided with the contact surface of fine hair on whole surface, wherein the surface texture of this shoe-pad is to be formed by institute's villous.This class shoe-pad is patent documentation EP-0 ' 225 ' 285 and US4 for example, and 760,655A discloses.Simultaneously at a back patent documentation CH686, among the 062A, it is identical being designed at the whole lip-deep height of naps of plug-in type shoe-pad, other be the holder lining (footbed) that forms foot that change and correspondingly actual for example according to the height of naps of the shoe-pad of patent documentation WO85/04786.This class shoe-pad in fact always too stimulates the vola, and the massage of Qi Wang plantar reflex area no longer shows desired effects like this.On the contrary, the result that is harmful to of undue stimulation meeting DIABLO warp and causing.The supplier of these footwear lays one's finger on: these class footwear should be worn 1-2 hour.

Have the shoe-pad of elastic foam material protuberance about manufacturing, known have two kinds of design principles.In a situation, shoe-pad is to go up in a harder shoe-pad substrate (base sole) to form, and adheres to the protuberance of similar cushion in this substrate.This is a very complicated and expensive manufacture method.For example can know this manufacture method among the 655A from above-mentioned document US-4,760.In order to make these protuberances still can obtain effective massage effect, these protuberances must be higher highlightedly with respect to substrate surface.Because the massage of not expecting that the fine hair cover layer attached to the footwear substrate and spread all on the whole shoe-pad, is felt on harder not outburst area is than stronger on outburst area.

By patent documentation DE-90 ' 02 ' 962.3 shoe-pad that forms of claim 1 preamble as can be known.Here, shoe-pad substrate and protuberance are that to be that 30 ° of foamed materials to 45 ° of Durometer A hardness are one-body molded by hardness manufacture an integral body.This shoe-pad preferably is made of plastics.It can be designed to the end in plug-in type shoe-pad and the footwear.In this known shoe-pad, shoe-pad substrate and protuberance are preferably formed by the synthetic material manufacturing.Traditional rubber (latex) is as natural products, and its hardness is the 10-20 Durometer A hardness.Although its hardness can be provided with De Genggao, yet can make product more expensive so on the one hand, and this on the other hand mixing is undesirable from physiology angle part.

If sensuously soft certain shoe-pad that is absorbed in the degree of depth (sinking depth) and enough elasticity degree of depth (spring depth) that has can be provided, so that can be delivered to the vola by the reflection area massage point in the mode that reduces, so just can very well realize soft effectively plantar reflecting region massage with conflicting firmly.

Therefore, the purpose of this invention is to provide a kind of shoe-pad that overcomes above-mentioned shortcoming and reach the above-mentioned type of above-mentioned effect simultaneously.

Above-mentioned purpose can be by having claim 1 the shoe-pad of technical characterictic realize.Because therefore the material that combination has selected to have suitable stiffness has obtained to have excellent physiological property and make simple product.

If make cover layer, can very well set the integral hardness of expection so on the one hand, and can obtain the combination of the most excellent connection material with leather.More favourable embodiment can be known by inference from dependent claims and their embodiment, and its importance will be set forth in the following description.Accompanying drawing has shown to inscribe states the preferred embodiment of subject matter, and is described in detail in the following description.Wherein:

Fig. 1 is the schematic diagram according to shoe-pad of the present invention, is provided with a kind of arrangement mode at plantar reflex area to be suitable for influencing head and sensory protuberance;

Fig. 2 is the schematic diagram that is provided with the shoe-pad of the protuberance that is suitable for influence (blood) circulation at the place, vola;

Fig. 3 is the amplification cross sectional representation along the line A-A among Fig. 1;

Fig. 4 is the sectional view along the line B-B among Fig. 2, and it has shown the embodiment of a variation outside the protuberance zone of shoe-pad;

Fig. 5 is the aforesaid sectional view of another kind of combination of materials;

Fig. 6 to Figure 11 has shown to have the shoe-pad that different protuberances constitute, for the different echo areas of autotelic influence, to act on corresponding organ and body part.

This shoe-pad is on the whole shown in Reference numeral 1.It comprises the flat shoe-pad substrate 2 of elastic foam material, and this elastic foam material is rubber or polyurethane in the present embodiment.Be provided with the protuberance 3 that a plurality of discernible and shoe-pad substrates 2 manufacture parts on flat shoe-pad substrate 2, it is made up of same material, so can be one-body molded.These protuberances 3 are positioned at the known reflector space in vola.Protuberance 3 is made into like this, and promptly its lateral inclination formula is to upper process and have a central horizontal surface 5.Between the non-protrusion surface of central plane 5 and shoe-pad substrate 2, be provided with circle-shaped lateral inclination portion 4.Such shape not only can make shoe-pad the time play the massage echo area in walking, and also can obtain pin during rest and press (attacking a vital point) (acupressure) effect, and effect is soft especially.

Protuberance is not that tubular shape must be arranged, and as shown in Figure 2, it can be designed to other profile.In particular, protuberance also can be a linear.Such linear protuberance 6 as shown in Figure 2.The linear protuberance has the same apex lines that highly forms in an edge.In general embodiment, all protuberances are all given prominence to the same extent outside the surface of shoe-pad substrate 2.

Shoe-pad substrate 2 comprises that one is the foamed elastomeric material layer and the cover layer of fixedlying connected with it 20 provided thereon that comprises rubber layer 10 here.This sponge layer has 10 ° to 20 ° Durometer A hardness.Because it is thinner relatively to be positioned at the thickness of the rubber layer 10 that does not have the protuberance zone, between 1.5mm to 4.0mm, so the relatively large difference of hardness of rubber layer will produce bigger influence.In addition, but also because the size localized variation in hole.When using the higher rubber layer of Shore hardness, this difference also still exists.The match materials of suggestion can be adjusted this difference widely according to the present invention, and can have corresponding expection characteristic on the whole can clear definite hardness.With those only in the echo area just with the known insole shaped of the protuberance of cushion material in pairs than, formed and compared the shoe-pad that those known shoe-pads that very big difference in hardness arranged play damping action on the whole better in protuberance zone and protuberance neighboring region.

In fact therefore the basic thickness of rubber layer or sponge layer can be any thickness owing to will combine with cover layer here.The selection of thickness is such in this case, promptly would rather select thicker design to the shoe-pad of fixedlying connected with shoes, then would rather select thin design to the plug-in type shoe-pad.Yet basically, shoe-pad are thick more, and be sagging in order to compensate, and the absolute altitude of protuberance is big more.

Known formation leather covered layer is with advantageous particularly.In the present invention, on the one hand the pliability that expectation is good to be to guarantee the surperficial mobility of whole shoe-pad 1, can use on the other hand adhesive harmless on the physiology is realized for example bonding between rubber layer 10 and the cover layer 20 of sponge layer.These also can be realized as cover layer by using leather.The cover layer of making double-layer fur leather (split leather) simultaneously is particularly advantageous.Double-layer fur leather is not only favourable on price, and it has the consistency of thickness on whole surface and soft consistent advantage when touching.At manufacture view, the double-layer fur leather can very well form the profile of the shape that requires manufacturing.So also just permission is one times or twice of area thickness outside the protuberance at the height of the protuberance that forms on the sponge layer correspondingly.Adopt the double-layer fur leather in fact can also arbitrarily set sponge layer and tectal optimum thickness ratio.Therefore the integral hardness of shoe-pad expectation can be set at the several years Durometer A hardness.According to the present invention, can realize hardness is set between 30 ° to the 45 ° Durometer A hardness.

Yet senior more design just needs to use expensive upper strata skin more, therefore just need select the leather of stock's various hardness.

Up to the present, shoe-pad all still is to use the homogenous material manufacturing of the final hardness with expectation to form, perhaps use the material of pairing, but so just on whole surface, produced zone with different hardness, the present invention now proposes a kind of technical scheme for the first time, adopt two kinds on the whole surface of shoe-pad substrate 2 all uniform two kinds of materials realize the setting of hardness, but adopt the final hardness of the expectation that the material pairing produces and do not correspond to a kind of hardness in two kinds of materials.In the present invention, the selection of material is favourable from ecological view not only, and says it also is favourable from economic angle.Can use relatively thin rubber layer, and select relative thin, the cheap rubber that Durometer A hardness is low relatively, that can obtain from the market of thickness among the present invention, and be to adopt the double-layer fur that the material pairing can well be set to remove from office on the other hand.

As mentioned above, sponge layer can be made by polyurethane foam.Here preferably with the similar hardness of natural rubbery foam.Yet also can make this sponge layer, shown in Figure 4 and 5 by two material layers.

The cover layer 20 of TR thin rubber layer 10 and leather, the water vapor permeability of measuring according to DIN DIN5333 is 6.9mg/cm³This just means that shoe-pad according to the present invention is better relatively to the absorption of sweat.In addition, the gas permeability of this shoe-pad is 8.51/min when pressure is 0.01 crust.But therefore shoe-pad according to the present invention through a night after sweat dissipation.Yet these desired effects also mean relatively low heat insulating ability.This can reduce widely according to the present invention, promptly adds one deck foamed polyurethane or make whole froth bed with this material under rubber layer.Test shows, product (description) Sanitized^The polyurethane through antibacterium and antimycotic processing of PUR99-45 is specially suitable.This material can be provided by French Clariant Huningue SA company in Switzerland.The hardness of this material is 20-24 Shore hardness C at this, adopts the method that is similar to according to DIN53505 to measure.Thickness is that the layer of polyurethane of 4-7mm has good heat-insulating property.Although layer of polyurethane 30 is softer relatively, this shoe-pad still maintains the whole structure of massage effect or pin pressure (attacking a vital point) effect.

Under the froth bed that can be individual layer or bilayer,, then preferably add product texon as can be holistic shoe-pad^, cork dust or cellulose layer 40.This layer 40 is harder relatively.It also can be as the shoe-pad of assembling upper of a shoe (shoe uppers) simultaneously.

If sole inner face unevenness, then the relative hardness of layer 40 is mechanically protected shoe-pad.Therefore it can be used as the part of shoe-pad.

If select Double-layer insole, then preferably on layer of polyurethane, cover rubber layer by rubber and polyurethane be combined into.Even when using Sanitized^PUR 99-45 also can realize antibacterium and antimycotic effect by the rubbery foam layer during as polyurethane foam.

Except the embodiment of Fig. 1 and Fig. 2, it will also be appreciated that the arrangement mode of other various protuberances, to be used for targetedly influence in the different echo areas of the appropriate section of corresponding organ or health.Simultaneously, up at present, in fact it is very general having only those shoe-pads with protuberance of general application arrangement, what the shoe-pad of design can be made according to the present invention is better more accurate, also therefore provide for the first time the shoe-pad that targetedly influences some organ or some position of health of a whole set of series, for you to choose.Therefore, Fig. 6 shows a kind of arrangement that acts on the protuberance of back bottom, and Fig. 7 shows a kind of arrangement that acts on the protuberance of sexual organ, and Fig. 8 shows a kind of arrangement of protuberance of the plantar reflecting region that influences spine regions.Fig. 9 is the arrangement that influences the protuberance of shoulder girdle and pelvis area, and simultaneously, Figure 10 has disclosed the arrangement that influences Alimentary protuberance.At last, Figure 11 shows and is used to influence neurovegetative shoe-pad.

Because the undue excitant that general now shoe-pad causes can not provide such shoe-pad when reckoning without possible injury at the same time.
