Abstract
In order to relieve the locomotor system of the lower extremities by the elastic absorption of hard impacts within the calcaneal region, in an orthopedic support (100) with an even underside and a top side (102) fi-nished so as to form a foot bed or a heel bed (10) with at least one padding-like region (20; 20') within the area of pressure-sensitive points of the foot, more especially of the calcaneal spur, wherein the support (100) and the padding-like region (20; 20') are compri-sed of a plastic, more particularly a silicone rubber of identical hardness, the padding-like region (20; 20') being formed by a section (A) in the support (100) which, on the underside of the support (100), is provi-ded with a concave depression or recess so that, bet-ween the support and its bearing surface in a shoe, wi-thin the area of the depression, an air pad is formed (fig.1).
Description
~ - - 216786~
Orthopedic Support The invention relates to an orthopedic support with an even underside and a top side that is finished to as to form a foot bed or a heel bed having at least one pad-ding-like region within the area of pressure-sensitive points of the foot, more especially of the caLcaneal spur, in which case the support and the padding-like region are comprised of a plastic, more particularly, a silicone rubber.
BACKGROUND OF THE INVENTION
From the DE-GM 87 OO 689, an orthopedic support or foot bedding is known which possesses a substantially even underside adapted to an inner shoe and a top side fi-nished so as to form a foot bed within the region of the pressure-sensitive points of the foot, in which, into a basic material of low elasticity, pads of sili-cone rubber are inserted or placed underneath or put upon the basic material. With such a support, especially when large-surface paddings are involved, it is suppo-sed to be possible to achieve improved wearing proper-ties which, in the case of pressure-sensitive changes or diseases of the foot, bring about a substantial palliation of the paon by virtue of the specific proper-ties of the silicone rubber. Due to the circumstance that the padding material employed possesses an enhan-ced wearing behavior on account of high elastic recovery forces and good impact shock absorption, this orthopedic support can be employed as a supporting or correcting aid in acquired or congenital malformations of the foot and wherever a pain alleviation and a good pressure dis-tribution, e.g. in inflammatory diseases of the foot, are desired.

Due to the circumstance that the padding material employed possesses an enhan-ced wearing behavior on account of high elastic recovery forces and good impact shock absorption, this orthopedic support can be employed as a supporting or correcting aid in acquired or congenital malformations of the foot and wherever a pain alleviation and a good pressure dis-tribution, e.g. in inflammatory diseases of the foot, are desired.
- 2 - 2167865 The fabrication of heel pads from silicone rubber is known from "Orthop3dietachnik", 11/87, Pages 654 through 655. Such a heel pad serves to care for the rear of the foot within the calcaneal area and, in particular, where a shock absorption is desired within the calca-neal area or in the case of a plantar calcaneal spur.
In this connection, the qualities of the silicone rub-ber are utilized which makesa uniform pressure distribu-tion possible, intercepts impact shock loads and thus possesses substantial cushioning properties.
The DE-GM 78 34 409 describes a foot bed, more esp~ci-ally an insole for the orthopedic therapy of foot troub-les with a support that is adapted to the anatomical con-ditions of the foot, in which case a padding layer of an elastic material is disposed on the support. This pad-ding layer is comprised of a silicone rubber. Such a silicone rubber padding layer adapts optimally to the anatomical conditions of the foot, in which case virtu-ally at all points of the foot the same specific surface pressure results. A padding layer of a silicone rubber has to possess a high degree of resilience or springi-ness, which can be put down to the fact that the sili-cone rubber, when subjected to a load, yields vertically laterally to the layer and thereby, within adjacent areas, undergoes an increase in volume, which has a sup-porting effect within this area. When walking, it is in-tended to thereby achieve a constant light massage of the foot surfaceaiding the blood circulation of the foot. By birtue of its elastic properties, the silicone rubber intercepts impacts and shocks, whereby the strain on the foot, the knee, the hip joint and even on the spinal column is reduced. However, this lateral displa-cement of the material occurring when the padding layer of silicone rubber is subjected to a load is possible only if the padding layer is disposed on a suppor-ting means.
From the DE-GM 88 00 116, a heel pad of silicone rubber with a heel bedding and, possibly, a shell following marginally thereon is known, in which case the heel bed possesses a region of silicone rubber which is standar-dized so as to be softer. This region which is inten-ded to be a padding of a silicone rubber padding which is standardized to be softer is embedded in the silicone rubber standardized so as to be harder of the heel pad.
In this heel pad and in all cases where the padding is comprised of a silicone rubber which, in comparison with the material of the insole or of the heel pad, is standardized so as to be softer, the disadvantage of a formation of material accumulation within the marginal area of the padding when the padding is subjected to a load or acted upon by a pressure results, in the way in which the same corresponds to the pressure exerted by the calcalean spur upon the padding. By the action of the pressure, the padding material endeavors to get out of the way laterally and since the lateral material dis-placements cannot be taken up or absorbed by the mate-rial of the insole or of the foot bed because their material, in comparison with the material of the pad-ding, is standardized to as to be harder, thus to pos-sess a higher Shore hardness, this results in material accumulations occurring within the marginal padding area in the form of bead-like elevated portions or wave-like formations which do not contribute to a pressure relief of the foot, but exert a pressure on the sole of the foot, the calcalean spur or the heel of the foot, whereby the actual desired orthopedic effect is impai-red and, consequently, pains do develop.
~ ~ - 216786~
In contrast to that it is the technical problem of the present invention to provide an orthopedic support ac-cording to the type described in the beginning, in which not merely the occurrence of unwelcome high pressure loads is avoided, but also the material displacements giving rise to pains within the area of a pressure ef-fect are prevented. The material displacement or mate-rial compression occurring due to an acting load or pressure within the area acted upon by pressure are in-tended to be taken up by the adjacent material and ab-sorbed in the support or by the foot bed.
SUMMARY OF THE INVENTION
This technical problem is resolved in such an orthopedic support by means of the features stated in Claim 1.
By means of the construction according to the invention of the orthopedic support with a padding like region, whose underside facing away from the sole of the foot is provided with a concave recess, strains imposed on muscles, tendons and joins caused by movement are ab-sorbed, whereby a premature wear is prevented and painful conditions are palliated. The entire support is comprised of a plastic, more particularly a sili-cone rubber which distinguishes itself by a great softness and a high degree of elasticity. The cushio-ning of impact loads is effected by means of the special underside construction of the padding-like region formed in the support. A material displacement within the pad-ding-like region which occurs when subjected to a load or when a pressure is applied is absorbed by the conca-ve recess on the underside of the padding-like region so that no material accumulations occur within the plan-tar or calcaneal or calcaneal spur region when the pad-ding-like region is subjected to a load or when a - 21~78~5 pressure is exerted upon the padding-like region. The material of the padding-like region which is trying to get away laterally is displaced into the concave recess on the underside of the padding-like region.
With the support according to the invention, the loco-motor system of the lower extremities is relieved by the elastic absorption of hard impacts, particularly with;n the area of the heel. The support, by virtue of the construction of the specially designed padding-like region, contributes toward a perceptible alleviation of painful conditions. By means of the formation of the padding-like region within the heel area or in a heel bed, the calcanean spur is pressure-relieved at cer-tain points within the critical region. An activation of tired feet takes place especially where a calcanean spur exists. Partial heel pressure is relieved immedia-tely. The support itself can, for a relief of the heel or of the calcanean spur, be provided with a padding-like region formed within the heel area. The length of the support may correspor,dto the length of the sole of the foot, it is possible, however, for constructions to be employed wherein the support covers two thirds of the planta, but dimensions of the support are also pos-sible when the same is to be employed exclusively as a heel bed.
Advantageous constructions of the invention are charac-terized in the subclaims.

ETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The orthopedic support 100 according to Figs. 1 and 5 is comprised of a plastic, more especially a silicone rubber, in which case an addition cross-linked silicone rubber is expediently used for the fabrication of the support.
This support 100 is provided with an even underside 101 and a top side 102 finished so as to form a foot bed 110 (Fig.5) or a heel bed 10 (Figs. 1 and 4). The support 100, particularly within the heel area F, is advanta-geously provided with a formed-on shell like rim 11 which, in the heel bed 10, extends up to the front edge 10a of the same and, in the foot bed 110, as far as into the forward area of the support.
21678~5 In the support 100, at least one region 20 or 20' or 30, within the area of pressure-sensitive points of the foot, is constructed which, on the underside 101 of the support 100, is provided with a concave depression or recess 23, which delimits and predetermines the region and which is acted upon by pressure and which acts in the form of a padding. The padding-like region 20,20' constructed within the heel area F of the heel bed 10 or of the foot bed 110 is disposed within the region of the calcanean spur acting upon the padding-like region or the section of the support 100. According to a further embodiment, the foot bed 110 of the orthopedic support 100 within the forward toe area or within the area of the ball of the foot, possesses a further padding-like region 30 so as to achieve a soft elastic or springably elastic cu-shioning of the foot also within this padding-like re-tion 30.
The padding-like region 20,20' or 30 is obtained in the foot bed 110 or in the heel bed 10 by the formation of the recess 23 on the underside 101 of the support 100.
The underside 101 of the support 100 is provided with the concave recess 23 so that, between the support 100 and the surface area upon which the orthopedic support 100 rests, a hollow space is formed which serves for the accommodation of material that tries to get away late-rally when the padding-like region is subjected to a load or when a pressure is exerted upon the same.
A soft-standardized plastic, more especially a silicone rubber, is employed for the manufacture of the support 100 or of the heel bed 10 or of the foot bed 110, in which case a silicone rubber is expediently used which possesses a hardness of from 2 through 15 Shore.
~1~78B5 The padding-like region 20,20' for supporting the heel and the calcanean spur possesses an oval or elliptical configuration, in which case the recess 23 receives the pertinent shape by means of which the padding-like re-gion 20,20' is predetermined or preset for the support of the calcanean spur. This padding-like region 20,Z0' is constructed in the support 100 in such a way that, when the support 100 is used, the padding-like region comes to be located underneath the calcanean spur or the same is supported on the padding-like region (Figs.
1 and 4). Also the padding-like region 30 within the forward foot area of the orthopedic support 100 or of the foot bed 110 possesses, according to Fig.5, a con-figuration which corresponds to a circular surface pas-sing into an ellipse. However, it is possible for the padding-like regions 20,20' or 30 to also possess other configurations.
The support 100 or the heel bed 10 or the foot bed 110 are comprised of a transparent or opaque springably elastic silicone rubber. In the fabrication of the sup-port 100, the support section, in which the padding-like regions 20,20',30 are constructed, can be dyed. This coloration of the padding has the advantage that, when supports possessing different Shore hardnesses are em-ployed, it will then be possible to immediately recog-nize by the respective coloration whether a support 100 with a softer or harder standardized plastic is involved.
* * * * *
In this connection, the qualities of the silicone rub-ber are utilized which makesa uniform pressure distribu-tion possible, intercepts impact shock loads and thus possesses substantial cushioning properties.
The DE-GM 78 34 409 describes a foot bed, more esp~ci-ally an insole for the orthopedic therapy of foot troub-les with a support that is adapted to the anatomical con-ditions of the foot, in which case a padding layer of an elastic material is disposed on the support. This pad-ding layer is comprised of a silicone rubber. Such a silicone rubber padding layer adapts optimally to the anatomical conditions of the foot, in which case virtu-ally at all points of the foot the same specific surface pressure results.

When walking, it is in-tended to thereby achieve a constant light massage of the foot surfaceaiding the blood circulation of the foot. By birtue of its elastic properties, the silicone rubber intercepts impacts and shocks, whereby the strain on the foot, the knee, the hip joint and even on the spinal column is reduced. However, this lateral displa-cement of the material occurring when the padding layer of silicone rubber is subjected to a load is possible only if the padding layer is disposed on a suppor-ting means.
From the DE-GM 88 00 116, a heel pad of silicone rubber with a heel bedding and, possibly, a shell following marginally thereon is known, in which case the heel bed possesses a region of silicone rubber which is standar-dized so as to be softer. This region which is inten-ded to be a padding of a silicone rubber padding which is standardized to be softer is embedded in the silicone rubber standardized so as to be harder of the heel pad.
In this heel pad and in all cases where the padding is comprised of a silicone rubber which, in comparison with the material of the insole or of the heel pad, is standardized so as to be softer, the disadvantage of a formation of material accumulation within the marginal area of the padding when the padding is subjected to a load or acted upon by a pressure results, in the way in which the same corresponds to the pressure exerted by the calcalean spur upon the padding. By the action of the pressure, the padding material endeavors to get out of the way laterally and since the lateral material dis-placements cannot be taken up or absorbed by the mate-rial of the insole or of the foot bed because their material, in comparison with the material of the pad-ding, is standardized to as to be harder, thus to pos-sess a higher Shore hardness, this results in material accumulations occurring within the marginal padding area in the form of bead-like elevated portions or wave-like formations which do not contribute to a pressure relief of the foot, but exert a pressure on the sole of the foot, the calcalean spur or the heel of the foot, whereby the actual desired orthopedic effect is impai-red and, consequently, pains do develop.

The padding-like region 20,20' constructed within the heel area F of the heel bed 10 or of the foot bed 110 is disposed within the region of the calcanean spur acting upon the padding-like region or the section of the support 100. According to a further embodiment, the foot bed 110 of the orthopedic support 100 within the forward toe area or within the area of the ball of the foot, possesses a further padding-like region 30 so as to achieve a soft elastic or springably elastic cu-shioning of the foot also within this padding-like re-tion 30.
The padding-like region 20,20' or 30 is obtained in the foot bed 110 or in the heel bed 10 by the formation of the recess 23 on the underside 101 of the support 100.
The underside 101 of the support 100 is provided with the concave recess 23 so that, between the support 100 and the surface area upon which the orthopedic support 100 rests, a hollow space is formed which serves for the accommodation of material that tries to get away late-rally when the padding-like region is subjected to a load or when a pressure is exerted upon the same.
A soft-standardized plastic, more especially a silicone rubber, is employed for the manufacture of the support 100 or of the heel bed 10 or of the foot bed 110, in which case a silicone rubber is expediently used which possesses a hardness of from 2 through 15 Shore.
~1~78B5 The padding-like region 20,20' for supporting the heel and the calcanean spur possesses an oval or elliptical configuration, in which case the recess 23 receives the pertinent shape by means of which the padding-like re-gion 20,20' is predetermined or preset for the support of the calcanean spur. This padding-like region 20,Z0' is constructed in the support 100 in such a way that, when the support 100 is used, the padding-like region comes to be located underneath the calcanean spur or the same is supported on the padding-like region (Figs.
1 and 4). Also the padding-like region 30 within the forward foot area of the orthopedic support 100 or of the foot bed 110 possesses, according to Fig.5, a con-figuration which corresponds to a circular surface pas-sing into an ellipse. However, it is possible for the padding-like regions 20,20' or 30 to also possess other configurations.
The support 100 or the heel bed 10 or the foot bed 110 are comprised of a transparent or opaque springably elastic silicone rubber. In the fabrication of the sup-port 100, the support section, in which the padding-like regions 20,20',30 are constructed, can be dyed. This coloration of the padding has the advantage that, when supports possessing different Shore hardnesses are em-ployed, it will then be possible to immediately recog-nize by the respective coloration whether a support 100 with a softer or harder standardized plastic is involved.
