Description

本発明は、使用する者の各種症状を改善することができるだけでなく、改善の効果を長期間にわたって十分に維持し得る履物及び履物の中敷に関し、特に、靴、サンダル、スリッパ、下駄等に好適なものである。   The present invention relates to footwear and an insole that can not only improve various symptoms of a user but also sufficiently maintain the effect of improvement over a long period of time, and in particular, shoes, sandals, slippers, clogs, etc. Is preferred.

従来、靴、サンダル、スリッパ、下駄等の履物やその中敷は、現代社会における人間活動において足の保護を図って活動領域を拡げる目的等のために欠かせないものとなっているが、足裏に接するこれらの履物の底部上面がほぼ水平になる構造とされているものが一般的である。しかし、人間の体重が履物に絶えず加わると共に、歩行に伴って履物の底部が変形したり摩耗したりすることも知られている。   Traditionally, footwear such as shoes, sandals, slippers, and clogs and insoles have become indispensable for the purpose of protecting the foot and expanding the field of activity in human activities in modern society. In general, the upper surface of the bottom of these footwear in contact with the back is substantially horizontal. However, it is also known that the weight of a person is constantly added to the footwear, and the bottom of the footwear is deformed or worn with walking.

この一方、使用する者の全体重が履物や中敷に加わるのに合わせて、履物や中敷は膝関節部位や腰部位の各種症状に対する影響も大きい。例えば、下記引用文献１には、Ｏ脚の矯正に関するものが開示されている。また、下記引用文献２には、使用することにより自然に背骨の湾曲やＯ脚やＸ脚の矯正に役立つ履物および履物用中敷に関するものが開示されている。さらに、下記引用文献３には、変形性膝関節症に罹患した患者、特にＯ脚の患者に大きな効果が得られる履物が開示されている。   On the other hand, as the overall weight of the user is applied to the footwear and the insole, the footwear and the insole have a great influence on various symptoms of the knee joint region and the waist region. For example, the following cited document 1 discloses one relating to correction of the O-leg. Also, the following cited document 2 discloses a footwear and an insole for footwear that are naturally useful for correcting the curvature of the spine and the correction of the O leg and the X leg. Furthermore, the following cited document 3 discloses footwear that can provide a great effect to a patient suffering from knee osteoarthritis, particularly a patient with an O-leg.

上記課題を解決した請求項１記載の発明は、足裏面が乗る履台の厚さを足内側から足外側にいくに従い厚肉としかつ足を覆って支持する支持部材を有してなる左右一組の履物であって、
履台の少なくとも接地面側とされる下面側が、耐摩耗性の高い難摩耗性材料により形成されることを特徴とする履物である。 The invention according to claim 1, which has solved the above-mentioned problem, has a support member that supports and covers the foot by increasing the thickness of the footrest on which the back of the foot rides from the inside of the foot to the outside of the foot. A pair of footwear,
The footwear is characterized in that at least a lower surface side which is a ground contact surface side of the footwear is formed of a wear-resistant material having high wear resistance.

請求項１の左右一組からなる履物によれば、足裏面が乗る履台の厚さを足内側から足外側にいくに従い厚肉としただけでなく、足を覆って足を支持するための支持部材を有していることから、使用者の歩行に伴って足と一体的に履物が移動することになる。また、足内側から足外側にいくに従って履台が厚くなるので、このような履物を履いた場合、履台が水平にされている場合と異なって足が身体の中心側に傾いて、身体の中心方向へ押す力が足に働くことになる。これに伴って膝関節部位や腰部位にも身体の中心に向かって力が加わって左右の膝及び腰が内側に押される。   According to the pair of left and right footwear according to claim 1, not only the thickness of the footrest on which the sole of the foot rests is thickened from the inside of the foot to the outside of the foot, but also for covering the foot and supporting the foot. Since the support member is provided, the footwear moves together with the foot as the user walks. In addition, since the platform becomes thicker as it goes from the inside of the foot to the outside of the foot, when such footwear is worn, the foot tilts toward the center of the body, unlike when the footwear is leveled, The force pushing toward the center acts on the foot. Along with this, a force is also applied to the knee joint part and the waist part toward the center of the body, and the left and right knees and the waist are pushed inward.

つまり、足の踝から上側部分に身体の中心側に向かって力が加わるので、この履物を履いて適宜に起立状態を維持したり、膝の曲げ延ばしをしたり、或いは歩行を繰り返すなどの運動をすることにより、内方向へ押す力が足に働くことで、各種症状が改善されることがある他、正常な人にあっては各種症状の発生を予防できるなどの効果がある。さらに、履台の少なくとも接地面側となる下面側が耐摩耗性の高い難摩耗性材料により形成されることで、歩行による摩耗が減少して上記の履台の形状が長期間にわたり維持されるのに伴い、各種症状改善等の効果も長期間維持される。   In other words, since force is applied from the heel to the center of the body toward the center of the body, exercise such as wearing this footwear to keep it standing properly, bend and extend the knee, or repeat walking By doing this, the force that pushes inward acts on the foot, so that various symptoms may be improved, and in normal people, the occurrence of various symptoms can be prevented. Furthermore, at least the lower surface side, which is the ground contact surface side, is formed of a wear-resistant material having high wear resistance, so that wear due to walking is reduced, and the shape of the above-mentioned platform is maintained for a long period of time.

Since the platform is laminated with a wear-resistant material and a hard-to-deformable material, the shape of the platform is stable, and as the shape of the platform is maintained over a longer period of time, the effect of improving various symptoms is further improved. Maintained for a long time.

請求項３では、難摩耗性材料が、樹脂材料の内の自己潤滑性を有したナイロン或いは高密度ＰＥとされている。このような材料を採用することとすれば、履台の形状が確実に長期間にわたり維持され、各種症状改善の効果も長期間維持されることになる。   In claim 3, the hard-wearing material is made of nylon or high-density PE having a self-lubricating property among the resin materials. If such a material is adopted, the shape of the platform is reliably maintained over a long period of time, and the effect of improving various symptoms is also maintained over a long period of time.

請求項４では、難変形性材料が、樹脂材料と繊維状材料からなる複合材料とされている。このような材料を採用することとすれば、履台の形状が確実に長期間にわたり維持され、各種症状改善の効果も長期間維持されることになる。   According to a fourth aspect of the present invention, the hardly deformable material is a composite material composed of a resin material and a fibrous material. If such a material is adopted, the shape of the platform is reliably maintained over a long period of time, and the effect of improving various symptoms is also maintained over a long period of time.

請求項５では、支持部材が弧状に形成されていて、問題なく足の甲に支持部材が係合うことで、より確実に使用者の歩行に伴って足と一体的に履物が移動するようになる。   In claim 5, the support member is formed in an arc shape, and the support member is engaged with the instep of the foot without any problem, so that the footwear can move together with the foot more reliably as the user walks. Become.

請求項６の左右一組からなる履物の中敷によれば、足裏面が乗る履物の履台上面に設置されて使用されるものの、中敷を足内側から足外側にいくに従い厚肉としている。さらに、履台の中敷が変形し難い難変形性材料により形成されることで、上記請求項２と同様に、中敷の形状が長期間にわたり維持されるのに伴って各種症状改善の効果も長期間維持される。   According to the insole of footwear comprising a pair of left and right according to claim 6, the insole is made thicker as it goes from the inside of the foot to the outside of the foot, although it is installed and used on the upper surface of the footwear of the footwear on which the sole of the foot rides . Furthermore, as the insole of the footrest is formed of a hardly deformable material that is difficult to be deformed, the effect of improving various symptoms can be maintained as the shape of the insole is maintained over a long period of time as in the case of claim 2 above. Is also maintained for a long time.

請求項７では、難変形性材料が、樹脂材料と繊維状材料からなる複合材料とされている。このような材料を採用することとすれば、上記請求項４と同様に、中敷の形状が確実に長期間にわたり維持され、各種症状改善の効果も長期間維持されることになる。   In the seventh aspect, the hardly deformable material is a composite material made of a resin material and a fibrous material.

以下、本発明の第１の実施形態に係る履物について図面を参照しつつ詳細に説明する。
本実施形態のサンダルである履物１０は、図１及び図２に示すように左右対称で一対の履物構成部材１０Ａ、１０Ｂから構成されている。 Hereinafter, footwear according to a first embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the footwear 10 that is a sandal of the present embodiment is symmetrical and includes a pair of footwear constituent members 10A and 10B.

図１及び図２に示すように履物１０の一方の履物構成部材１０Ａ（図２の左側）は、足裏面が乗る履台１２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉とし、シート状の上底板１４が履台１２の上面に接着されていて、この履台１２の上面に配置された上底板１４が水平線Ｈに対して一方の側縁から他方の側縁に向かって傾斜させた構造とされている。また、履台１２の前側の両側縁には、弧状に形成されて足を覆いつつ足を支持する支持部材である胛皮１６の両側縁が、それぞれ接着または逢着されていて、履台１２の上面と上底板１４の下面とでこの胛皮１６の接着縁部分を挟みつけている。   As shown in FIGS. 1 and 2, one footwear component 10A (left side in FIG. 2) of the footwear 10 is thicker as the thickness of the footrest 12 on which the back of the foot rests increases from the foot inner side LA to the foot outer side LB. The sheet-like upper bottom plate 14 is bonded to the upper surface of the footrest 12, and the upper bottom plate 14 disposed on the upper surface of the footrest 12 is directed from one side edge to the other side edge with respect to the horizontal line H. The structure is inclined. Further, both side edges of the crust 16, which is formed in an arc shape and supports the foot while supporting the foot, are bonded or attached to the both side edges on the front side of the footrest 12, respectively. An adhesive edge portion of the scab 16 is sandwiched between the upper surface and the lower surface of the upper bottom plate 14.

この一方、履物１０の他方の履物構成部材１０Ｂ（図２の右側）に関しても、足裏面が乗る履台１２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉とし、シート状の上底板１４が履台１２の上面に接着されていて、履台１２の上面に配置された上底板１４が水平線Ｈに対して一方の側縁から他方の側縁に向かって傾斜させた構造とされている。尚、他の部分は上記と同様の構造とされている。   On the other hand, with respect to the other footwear component 10B (the right side in FIG. 2) of the footwear 10, the thickness of the footrest 12 on which the foot sole is placed is increased from the foot inner side LA to the foot outer side LB. The bottom plate 14 is bonded to the upper surface of the platform 12, and the upper bottom plate 14 disposed on the upper surface of the platform 12 is inclined with respect to the horizontal line H from one side edge toward the other side edge. ing. The other parts have the same structure as described above.

以上より、本実施形態の履物１０を構成する左右対称で一対の履物構成部材１０Ａ、１０Ｂは、この履物１０を履いて使用する使用者の身体中心（一点鎖線Ｃで表す）寄り部分がそれぞれ低く形成されることになる。また、使用者が路面Ｒ上を歩く際には、胛皮１６の存在により足を持ち上げても履物１０の各履物構成部材１０Ａ、１０Ｂが足と一体的に移動する。   As described above, the pair of symmetrical footwear constituent members 10A and 10B constituting the footwear 10 of the present embodiment has a lower portion near the body center (represented by the alternate long and short dash line C) of the user who wears the footwear 10 and uses it. Will be formed. Further, when the user walks on the road surface R, the footwear components 10A and 10B of the footwear 10 move integrally with the foot even if the foot is lifted due to the presence of the scab 16.

さらに、各履台１２は、一般に動物の皮革、天然ゴム、ポリウレタン、プラスチック、人工ゴム等により構成されるが、本実施例においては、耐摩耗性の高い難摩耗性材料である樹脂材料の内の自己潤滑性を有したナイロン或いは高密度ＰＥ（ポリエチレン）により、接地面側となる下面側を含めて各履台１２が形成されている。   Further, each of the footrests 12 is generally composed of animal leather, natural rubber, polyurethane, plastic, artificial rubber, or the like. In this embodiment, among the resin materials that are highly wear-resistant and hard-wearing materials, Each of the footrests 12 is formed of the self-lubricating nylon or high-density PE (polyethylene) including the lower surface side which is the ground contact surface side.

次に、本実施形態における履物１０の作用を以下に説明する。
本実施形態の図１及び図２に示すような左右一組からなる履物１０によれば、足裏面が乗る履台１２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉としただけでなく、足を覆って足を支持するための胛皮１６を有しているため、使用者の歩行に伴って足と一体的に履物１０の各履物構成部材１０Ａ、１０Ｂが移動することになる。 Next, the operation of the footwear 10 in this embodiment will be described below.
According to the footwear 10 consisting of a pair of left and right as shown in FIG. 1 and FIG. 2 of the present embodiment, the thickness of the footrest 12 on which the foot sole is placed is made thicker as it goes from the foot inner side LA to the foot outer side LB. In addition, since the scab 16 for covering the foot and supporting the foot is provided, the footwear component members 10A and 10B of the footwear 10 move integrally with the foot as the user walks. Become.

また、各履物構成部材１０Ａ、１０Ｂは、足内側ＬＡから足外側ＬＢにいくに従って履台１２が厚くなるので、このような履物１０を履いた場合、履台１２が水平にされている場合と異なって足が身体の中心側に傾いて、身体の中心方向へ押す力が足に働き、図示しない膝関節部位や腰部位にも身体の中心（一点鎖線Ｃで表す）に向かって力が加わって左右の膝及び腰が内側に押される。   Moreover, since each footwear component 10A, 10B becomes thicker in the footwear 12 as it goes from the foot inner side LA to the foot outer side LB, when such footwear 10 is worn, the footwear 12 is horizontal. Differently, the foot tilts toward the center of the body, and the force pushing toward the center of the body acts on the foot, and the force is also applied to the knee joint part and the waist part (not shown) toward the center of the body (represented by a dashed line C). The left and right knees and hips are pushed inward.

つまり、足の踝から上側部分に身体の中心側に向かって力が加わるので、この履物１０を履いて適宜に起立状態を維持したり、膝の曲げ延ばしをしたり、或いは歩行を繰り返すなどの運動をすることにより、足に内方向へ押す力が働くことで、各種症状が改善されることがある他、正常な人にあっては各種症状の発生を予防できるなどの効果がある。   That is, since force is applied from the heel of the foot toward the center of the body toward the center of the body, the footwear 10 can be used to maintain a proper standing state, bend and extend the knee, or repeat walking, etc. By exercising, the force exerted on the foot inwardly works, so that various symptoms may be improved, and in normal people, the occurrence of various symptoms can be prevented.

他方、履物の履台は一般的に使用により摩耗するものの、本実施形態では履台１２の少なくとも下面側となる接地面側が上記のように耐摩耗性の高い難摩耗性材料である自己潤滑性を有したナイロン或いは高密度ＰＥにより形成されている。このことから、使用者が歩行しても履台１２の下面側の路面Ｒによる摩耗が減少して、上記の履台１２の形状が長期間にわたり維持されるのに伴い、各種症状改善等の効果も長期間維持されるようになる。   On the other hand, although the footwear platform is generally worn by use, in the present embodiment, at least the lower surface side of the footwear 12 is a self-lubricating material in which the ground contact surface side is a wear-resistant material having high wear resistance as described above. It is made of nylon with high density or high density PE. From this, even when the user walks, wear due to the road surface R on the lower surface side of the platform 12 is reduced, and as the shape of the platform 12 is maintained over a long period of time, various symptoms are improved. The effect is also maintained for a long time.

次に、本発明の第２の実施形態に係る履物について図面を参照しつつ詳細に説明する。
本実施形態のサンダルである履物１０は、図３に示すように第１の実施形態と似た構造とされている。
図３に示すように前述の実施形態とほぼ同一であるが、前述では各履台１２全体が耐摩耗性の高い難摩耗性材料とされるのに対して、本実施形態では、各履台１２の下側にソール部１２Ａを設けこのソール部１２Ａを難摩耗性材料とし、各履台１２のソール部１２Ａと上底板１４との間の本体部１２Ｂを変形し難い難変形性材料により形成している。つまり、本実施形態の履物１０の履台１２は、難摩耗性材料と難変形性材料とを積層した構造とされている。 Next, footwear according to a second embodiment of the present invention will be described in detail with reference to the drawings.
The footwear 10 which is the sandal of this embodiment has a structure similar to that of the first embodiment as shown in FIG.
As shown in FIG. 3, it is almost the same as that of the above-described embodiment. In the above-described embodiment, the entire platform 12 is made of a wear-resistant material having high wear resistance. 12 is provided with a sole portion 12A that is made of a hard-wearing material, and the main body portion 12B between the sole portion 12A and the upper bottom plate 14 of each footrest 12 is made of a hard-to-deformable material. doing. That is, the footwear 12 of the footwear 10 of this embodiment has a structure in which a hard-wearing material and a hard-to-deform material are laminated.

さらに履物１０の各履物構成部材１０Ａ、１０Ｂの各履台１２を構成する本体部１２Ｂの厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉とすることで、履台１２の上面に配置された上底板１４が水平線Ｈに対して一方の側縁から他方の側縁に向かって傾斜した構造とされている。   Furthermore, the thickness of the main body 12B constituting each footwear 12 of each footwear component 10A, 10B of the footwear 10 is increased from the foot inner side LA to the foot outer side LB, so that it is arranged on the upper surface of the footwear 12. The formed upper bottom plate 14 is inclined with respect to the horizontal line H from one side edge toward the other side edge.

また、本実施形態の上記難変形性材料としては、例えば複数の材料を混合して作成した複合材料を採用することが考えられる。具体的には難変形性材料として、ガラス繊維等とした繊維状材料と樹脂材料とからなる複合材料である繊維強化プラスチック（ＦＲＰ）とする。但し、ポリアミド、ポリアセタール等の樹脂材料や他の材料を採用することも考えられる。   Moreover, as the said hardly deformable material of this embodiment, it is possible to employ | adopt the composite material created, for example by mixing several materials. Specifically, a fiber-reinforced plastic (FRP) which is a composite material composed of a fibrous material such as glass fiber and a resin material is used as the hardly deformable material. However, it is also possible to adopt resin materials such as polyamide and polyacetal and other materials.

次に、本実施形態における履物１０の作用を以下に説明する。
本実施形態も前記第１の実施形態と同様に、履台が水平にされている場合と異なって、内方向へ押す力が足に働き、足が内側に傾いて左右の膝が内側に押されるために、膝関節部位や腰部位に身体の中心（一点鎖線Ｃで表す）に向かって力が加わる。 Next, the operation of the footwear 10 in this embodiment will be described below.
Similarly to the first embodiment, the present embodiment also differs from the case where the platform is leveled, the force pushing inward acts on the foot, the foot tilts inward, and the left and right knees are pushed inward. Therefore, a force is applied to the knee joint part and the waist part toward the center of the body (represented by a one-dot chain line C).

但し、本実施形態の履物１０では、難摩耗性材料と難変形性材料とを積層した構造と履台１２がされている。このため、一般に使用に伴い履物の履台は使用者の体重や歩行等により変形するものの、本実施形態では、履台１２の上側寄り部分の本体部１２Ｂが変形し難い難変形性材料である例えば樹脂材料と繊維状材料からなる複合材料により形成されている。
このことで、履物１０の長期間の使用に対して、難摩耗性材料によるソール部１２Ａの存在により履台１２が摩耗しにくくなると共に、難変形性材料による本体部１２Ｂの存在により履台１２が変形しにくくなる。従って、上記の履台１２の形状が長期間にわたり維持されるのに伴い、各種症状改善等の効果も長期間維持されるようになる。 However, in the footwear 10 of the present embodiment, the footwear 12 and the structure in which the hard-wearing material and the hard-to-deformable material are laminated are provided. For this reason, although the footwear platform is generally deformed by the user's weight, walking, or the like with use, in this embodiment, the main body portion 12B of the upper portion of the footwear 12 is a hardly deformable material that is difficult to deform. For example, it is formed of a composite material composed of a resin material and a fibrous material.
As a result, the footwear 12 is less likely to be worn due to the presence of the sole portion 12A made of a hard-wearing material for long-term use of the footwear 10, and the footwear 12 is brought about by the presence of the main body portion 12B made of the hard-to-deformable material. Becomes difficult to deform. Therefore, as the shape of the platform 12 is maintained over a long period of time, effects such as improvement of various symptoms are also maintained over a long period of time.

以上より、第１の実施形態では、履台１２を構成する材料として耐摩耗性の高い難摩耗性材料を採用したが、第２の実施形態では、履台１２が難摩耗性材料と難変形性材料とを積層した構造として、摩耗しにくくなるだけで無く変形し難くなった。尚、これら難摩耗性材料と難変形性材料とを交互に複数積層して履台１２を形成しても良く、難摩耗性材料でありかつ難変形性材料とされる材料を採用しても良い。   As described above, in the first embodiment, the wear-resistant material having high wear resistance is adopted as the material constituting the footwear 12. However, in the second embodiment, the footwear 12 is made of the hard-wearing material and hardly deformed. In addition to being hard to wear, it has become difficult to be deformed as a structure laminated with a functional material. The footwear 12 may be formed by alternately laminating a plurality of these hard-wearing materials and hard-to-deformable materials, or a material that is a hard-wearing material and is made of a hard-to-deformable material may be adopted. good.

次に、本発明の第３の実施形態に係る履物について図面を参照しつつ詳細に説明する。
本実施形態の靴である履物２０は、図４及び図５に示すように第１の実施形態と似た構造とされている。
上記第１、第２の実施形態ではサンダルを例として説明したが、図４及び図５に示すように靴である履物２０に適用しても良い。本実施形態も前述の実施形態とほぼ同一構造であるが、靴であることから足Ｋを覆いつつ足Ｋを支持する支持部材である胛皮２６が、履台２２の全周囲にわたって接着または逢着されている。 Next, footwear according to a third embodiment of the present invention will be described in detail with reference to the drawings.
Footwear 20 which is a shoe of this embodiment has a structure similar to that of the first embodiment as shown in FIGS. 4 and 5.
In the first and second embodiments, the sandals have been described as an example, but the present invention may be applied to footwear 20 that is a shoe as shown in FIGS. Although this embodiment also has substantially the same structure as that of the above-described embodiment, since the shoe is a shoe, the heel cover 26 that supports the foot K while covering the foot K is bonded or attached to the entire circumference of the footrest 22. Has been.

また、本実施形態も各履台２２の下側にソール部２２Ａを設けこのソール部２２Ａを難摩耗性材料とし、各履台２２のソール部２２Ａと上底板２４との間の本体部２２Ｂを変形し難い難変形性材料により形成している。このため、本実施形態の履物２０の履台２２も、第２の実施形態と同様に難摩耗性材料と難変形性材料とを積層した構造とされている。   Also, in this embodiment, a sole portion 22A is provided on the lower side of each footrest 22 and this sole portion 22A is made of a hard-wearing material, and a main body portion 22B between the sole portion 22A and the upper bottom plate 24 of each footrest 22 is provided. It is made of a hardly deformable material that is difficult to deform. For this reason, the footwear 22 of the footwear 20 of the present embodiment also has a structure in which a hard-wearing material and a hard-to-deformable material are laminated as in the second embodiment.

そして、履物２０の一方の履物構成部材２０Ａは、足裏面が乗る履台２２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉とし、シート状の上底板２４が履台２２の上面に接着されていて、この履台２２の上面に配置された上底板２４が水平線Ｈに対して一方の側縁から他方の側縁に向かって傾斜させた構造とされている。   One footwear component 20 </ b> A of the footwear 20 is thicker as the footrest 22 on which the back of the foot rides increases from the foot inner side LA to the foot outer side LB. The upper bottom plate 24 disposed on the upper surface of the footrest 22 is inclined with respect to the horizontal line H from one side edge toward the other side edge.

この一方、履物２０の他方の履物構成部材２０Ｂに関しても、足裏面が乗る履台２２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉とし、シート状の上底板２４が履台２２の上面に接着されていて、履台２２の上面に配置された上底板２４が水平線Ｈに対して一方の側縁から他方の側縁に向かって傾斜させた構造とされている。尚、他の部分は上記と同様の構造とされている。   On the other hand, with respect to the other footwear constituent member 20B of the footwear 20, the thickness of the footwear 22 on which the foot sole is placed increases from the foot inner side LA to the foot outer side LB. The upper bottom plate 24 arranged on the upper surface of the footrest 22 is inclined with respect to the horizontal line H from one side edge toward the other side edge. The other parts have the same structure as described above.

本実施形態の場合も第２の実施形態と同様に、履物２０により内方向へ押す力が足に働き、足が内側に傾いて左右の膝が内側に押されるために、膝関節部位や腰部位に体の中心に向かって力が加わる。そして、使用者が歩行しても履台２２の下面側の路面Ｒによる摩耗が減少して、上記の履台２２の形状が長期間にわたり維持されるのに伴い、各種症状改善等の効果も長期間維持されるようになる。   In the case of this embodiment as well, as in the second embodiment, the force that pushes inward by the footwear 20 acts on the foot, and the foot tilts inward and the left and right knees are pushed inward. A force is applied toward the center of the body. And even if a user walks, the wear by the road surface R on the lower surface side of the footrest 22 is reduced, and as the shape of the footrest 22 is maintained for a long period of time, effects such as improvement of various symptoms are also obtained. It will be maintained for a long time.

次に、本発明の第４の実施形態に係る中敷について図面を参照しつつ詳細に説明する。
本実施形態の中敷３０が適用される靴である履物２０は、図６に示すように第３の実施形態と似た構造とされている。但し、第３の実施形態では、一対の履物構成部材２０Ａ、２０Ｂにおける足裏面が乗る履台２２の厚さを足内側ＬＡから足外側ＬＢにいくに従い厚肉な構造としているが、本実施形態では履台２２自体は平らな構造とされている。 Next, an insole according to a fourth embodiment of the present invention will be described in detail with reference to the drawings.
The footwear 20, which is a shoe to which the insole 30 of this embodiment is applied, has a structure similar to that of the third embodiment as shown in FIG. However, in the third embodiment, the thickness of the footrest 22 on which the soles on the pair of footwear constituent members 20A and 20B are placed increases in thickness from the foot inner side LA to the foot outer side LB. Then, the footrest 22 itself has a flat structure.

そして、本実施形態では、足裏面が乗る履物２０の履台２２上面に中敷３０がそれぞれ敷かれているという相違を有している。この中敷３０は、足内側ＬＡから足外側ＬＢにいくに従い厚肉とした構造とされている他、変形し難い難変形性材料により形成される。
また、本実施形態の中敷３０の材質としては、第２の実施形態のようにガラス繊維等とした繊維状材料と樹脂材料とからなる複合材料である繊維強化プラスチック（ＦＲＰ）としても良く、ポリアミド、ポリアセタール等の樹脂材料や他の材料を採用しても良い。 And in this embodiment, it has the difference that the insole 30 is each laid on the upper surface of the footwear 22 of the footwear 20 on which a foot sole rides. The insole 30 is formed of a hard-to-deformable material that is not easily deformed, in addition to a thicker structure from the foot inner side LA to the foot outer side LB.
Moreover, as a material of the insole 30 of this embodiment, it is good also as a fiber reinforced plastic (FRP) which is a composite material which consists of fibrous materials and resin materials, such as glass fiber like 2nd Embodiment, Resin materials such as polyamide and polyacetal, and other materials may be employed.

次に、本実施形態における履物２０の中敷３０の作用を以下に説明する。
履物２０の履台２２の上面が水平にされているものの、中敷３０が足内側ＬＡから足外側ＬＢにいくに従い厚肉とした構造とされている。このため、本実施形態も前記実施形態と同様に、内方向へ押す力が足に働き、足が内側に傾いて左右の膝が内側に押されるために、膝関節部位や腰部位に身体の中心に向かって力が加わる。 Next, the operation of the insole 30 of the footwear 20 in this embodiment will be described below.
Although the upper surface of the footwear 22 of the footwear 20 is horizontal, the insole 30 is structured to be thicker as it goes from the foot inner side LA to the foot outer side LB. For this reason, in this embodiment as well, the force pushing inward acts on the foot and the foot is tilted inward and the left and right knees are pushed inward. A force is applied toward the center.

また、一般に使用に伴い中敷は使用者の体重等により変形するものの、本実施形態では、中敷３０が変形し難い難変形性材料である樹脂材料と繊維状材料からなる複合材料により形成されている。このことで、履物２０の使用に対して中敷３０が変形しにくくなり、上記の中敷３０の形状が長期間にわたり維持され、これに伴って各種症状改善等の効果も長期間維持されるようになる。   In general, the insole is deformed by the user's weight or the like with use, but in this embodiment, the insole 30 is formed of a composite material made of a resin material and a fibrous material, which are difficult to deform. ing. As a result, the insole 30 is less likely to be deformed with respect to the use of the footwear 20, and the shape of the insole 30 is maintained over a long period of time, and accordingly, effects such as improvement of various symptoms are also maintained over a long period of time. It becomes like this.

以上のように、履物としてサンダル及び靴を例として説明したが、スリッパや下駄等の他の履物であっても同様な作用効果を奏するようになる。また、履物の中敷として靴の中敷を例として説明したが、他の履物に適用される中敷としても良い。   As described above, sandals and shoes have been described as examples of footwear, but similar effects can be obtained even with other footwear such as slippers and clogs. Moreover, although the insole of shoes was demonstrated as an example as an insole of shoes, it is good also as an insole applied to other footwear.

他方、耐摩耗性の高い難摩耗性材料としては、自己潤滑性を有したナイロン或いは高密度ＰＥ（ポリエチレン）等が考えられるが、摩擦係数を下げるオイル等の添加物を混ぜた樹脂材料や他の硬質プラスチック等であっても良い。また、難変形性材料としては、繊維状材料と樹脂材料とからなる複合材料である繊維強化プラスチック（ＦＲＰ）、ポリアミド、ポリアセタール等の樹脂材料の他、ポリオレフィン系樹脂や他のヤング率の高い他の硬質プラスチック等であっても良い。さらに、前述のように難摩耗性材料と難変形性材料とを交互に複数積層して履台や中敷を形成しても良く、難摩耗性材料でありかつ難変形性材料とされる材料を採用しても良い。   On the other hand, as a highly wear-resistant material having high wear resistance, self-lubricating nylon or high-density PE (polyethylene) can be considered, but a resin material mixed with an additive such as oil that lowers the coefficient of friction or the like. The hard plastic may be used. In addition, as hard-to-deform materials, in addition to resin materials such as fiber reinforced plastic (FRP), polyamide, and polyacetal, which are composite materials composed of fibrous materials and resin materials, polyolefin resins and other high Young's modulus materials The hard plastic may be used. Further, as described above, a plurality of alternately hard-wearing materials and hard-to-deformable materials may be alternately laminated to form a footwear or insole. May be adopted.
