- the load application time (toe contact time) is long, but the load peak value is low.
- the mesh upper material is soft and the toes are prone to dorsiflexion, making it easy to maintain the dorsiflexion state of the toes, but the upper material stretches when the toes contact, causing a load peak. It is thought to be lower. Therefore, in this case, the toes can be freely dorsiflexed, but it can be said that the toes are difficult to detect dorsiflexion. As shown in FIG.
- the peak value of the load is high and the load application time (toe contact time) is also long. This is because when the toes are dorsiflexed, the toes press against the toe pressing member 4 from the upper back side, and at this time, the toes pressing member 4 is made of a non-stretchable material (or a highly rigid material). Therefore, it is considered that the toe pressure contact member 4 is difficult to extend, and thus the toe pressure contact member 4 is in pressure contact with the toe (pressure sensor), and the load peak is likely to occur.

- the value of the myoelectric potential generated in the dorsiflexion phase from the swing leg period (around ⁇ 0.1 on the horizontal axis) to the time of ground contact (position 0 on the horizontal axis) before the contact is large. Therefore, when the myoelectric potential value is integrated in this dorsiflexion phase, the integrated value is larger in FIG. 5B than in FIG. 5A. As described above, the larger myoelectric potential integration value indicates that the muscle activity was actively performed. Therefore, when running with the shoes having the upper structure according to the present embodiment, the activity of the anterior tibial muscle is more active and the dorsiflexion of the foot and toes is more active than when running with bare feet. It turns out that it became.

Abstract
Description
本発明は、シューズのアッパー構造に関し、詳細には、シューズ着用者に足の背屈動作を認識させることができるようにするための構造の改良に関する。 The present invention relates to an upper structure of a shoe, and in particular, to an improvement of a structure for allowing a shoe wearer to recognize a dorsiflexion motion of a foot.
一般に、人が素足で歩く際には、人は足の底屈動作および背屈動作を交互に行うことにより、歩行を行っている。ところが、シューズを履いた際には、シューズのアッパーやソールにより足の自由度が制限されるため、足本来の底屈や背屈の動きが損なわれることになる。
このため、シューズを履く生活に慣れた現代人は、足および足指の活動が衰えているといわれている。その代表例が、浮趾(指先が地面に接地せずに浮いた状態)と呼ばれる症状である。
その一方、高齢者は、足の底屈および背屈動作が苦手であり、そのため、段差に躓いて転倒することが多い。このような高齢者についても、とくに足の背屈動作を認識させて、足および足指の動きを活性化させることができれば、歩行時の転倒を防止できるようになると考えられる。また、交通事故などによって下肢のリハビリが必要な患者についても、同様に、とくに足の背屈動作を認識させて、足および足指の動きを活性化させることができれば、下肢機能の回復につながることが期待される。
本発明は、このような従来の実情に鑑みてなされたもので、本発明が解決しようとする課題は、シューズ着用者の足の背屈運動を制限することなく、シューズを履いて歩行または走行した際にシューズ着用者に足の背屈動作を認識させることで、足および足指の動きを活性化させることができ、その結果、足本来の動きを取り戻させることができるシューズ用アッパー構造を提供することにある。
In general, when a person walks with bare feet, the person walks by alternately performing a plantar flexion action and a dorsiflexion action. However, when a shoe is worn, the degree of freedom of the foot is limited by the upper and sole of the shoe, so that the movement of the sole flexion or dorsiflexion of the foot is impaired.
For this reason, it is said that modern people accustomed to the life of wearing shoes are losing their foot and toe activities. A typical example is a symptom called buoyancy (a state in which a fingertip floats without touching the ground).
On the other hand, elderly people are not good at the plantar and dorsiflexion movements of their feet, so they often fall over steps. For such elderly people, it is considered that if they can recognize the dorsiflexion movement of the foot and activate the movement of the foot and toes, the fall during walking can be prevented. Similarly, for patients who need rehabilitation of the lower limbs due to traffic accidents, etc., if they can recognize the dorsiflexion of the foot and activate the movement of the foot and toes, it will lead to the recovery of lower limb function. It is expected.
The present invention has been made in view of such conventional circumstances, and the problem to be solved by the present invention is to walk or run while wearing shoes without restricting the dorsiflexion movement of the foot of the shoe wearer. By making the shoe wearer recognize the dorsiflexion of the foot when the shoe is worn, the upper structure for the shoe can be activated and the movement of the foot and toes can be activated. It is to provide.
請求項1の発明に係るシューズ用アッパー構造は、伸縮性材料から構成され、着用者の足の少なくともつま先部を覆うアッパー本体と、アッパー本体において足の足指に対応する位置に設けられかつその周囲がアッパー本体により囲繞されるとともに、非伸縮性材料から構成され、足の背屈時に足指がアッパー本体に接触した際に足指に対して上方から圧接する足指圧接部材とを備えている。
請求項1の発明によれば、着用者の足の少なくともつま先部を覆うアッパー本体が伸縮性材料から構成されているので、足の底屈時につま先部が屈曲する際に、アッパー本体が伸縮することで、足および足指の底屈の動きがアッパー本体により阻害されることなく、足の底屈運動を促進できる。
また、足の背屈時には、足指がアッパー本体に接触したとき、非伸縮性材料から構成された足指圧接部材が足指に上方から圧接する。これにより、着用者は、足の足指がアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できる。
しかも、この場合には、足指圧接部材の周囲が、伸縮性を有するアッパー本体により囲繞されていることにより、足の背屈時に足指がアッパー本体に接触したとき、足指圧接部材の周囲のアッパー本体が伸長することで、足および足指の背屈の動きがアッパー本体により阻害されることなく、足指がアッパー本体に接触している時間を長くして、足の背屈運動を促進できるとともに、足指圧接部材が足の足指に必要以上に圧力を及ぼすのを防止できる。
ところで、実公平4−18405号公報の第1図および第2図には、靴甲被(1)のつま先部(2)の内面に複数のつま先芯材(4、5)を積層したものが記載されている。
しかしながら、この場合には、つま先芯材の先端縁部がソール先端部まで延びているため、足の背屈時に足指がつま先芯材に接触したとき、つま先芯材の周囲の靴甲被がほとんど伸長することができず、足および足指の背屈の動きが靴甲被により阻害されることになる。また、このとき、つま先芯材が足の足指に必要以上に大きな圧力を及ぼすことになり、シューズ着用者に違和感や苦痛を与えることになる。
また、実公平6−49205号公報の第1図ないし第5図には、スポーツシューズ(1)の甲被部材(2)のつま先部分(4)につま先補強部材(5)を設けたものが記載されている。このつま先補強部材(5)は、本体部分(5a)と、その上に配置された補強部材(5b)とを有している。
しかしながら、この場合には、つま先補強部材の先端縁部がソール先端部に連結されているため(上記公報の第5図参照)、足の背屈時に足指がつま先部分に接触したとき、つま先補強部材の周囲の甲被部材がほとんど伸長することができず、足および足指の背屈の動きが甲被部材により阻害されることになる。また、このとき、つま先補強部材が足の足指に必要以上に大きな圧力を及ぼすことになり、シューズ着用者に違和感や苦痛を与えることになる。
これに対して、本願の請求項1の発明では、上述したように、足指圧接部材の周囲が、伸縮性を有するアッパー本体により囲繞されていることにより、足の背屈時に足指がアッパー本体に接触したとき、足指圧接部材の周囲のアッパー本体が伸長することで、足および足指の背屈の動きがアッパー本体により阻害されることなく、足の背屈運動を促進でき、足指圧接部材が足の足指に必要以上に圧力を及ぼすのを防止できる。
請求項2の発明では、請求項1において、足指圧接部材が、足の各足指に対応する位置に配置された複数個の部材から構成されている。
この場合には、足の背屈時に各足指がアッパー本体に接触したとき、非伸縮性材料から構成された各足指圧接部材が、それぞれ対応する各足指に上方から圧接する。これにより、着用者は、足の各足指がアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および各足指の動きを活性化できる。
請求項3の発明では、請求項2において、複数個の部材が、隣り合う各部材の間に設けられた連結部を介して互いに連結されている。
この場合には、足指圧接部材を構成する各部材が連結部を介して連結されていることにより、足の背屈時に各足指がアッパー本体に接触したとき、各部材の周囲のアッパー本体の伸長量を抑制して、足指圧接部材から足の各足指に作用する圧力を大きめに調整できる。その結果、足指の感覚が鈍くなった高齢者やリハビリの患者に好適のアッパー構造を実現できる。
請求項4の発明では、請求項2において、複数個の部材が互いに分離して設けられている。
この場合には、足指圧接部材を構成する各部材の周囲が、伸縮性を有するアッパー本体により囲繞されていることにより、足の背屈時に各足指がアッパー本体に接触したとき、各部材の周囲のアッパー本体がそれぞれ独立して伸長することができ、その結果、各足指の背屈運動を一層促進できるようになる。
請求項5の発明では、請求項1において、足指圧接部材が、足の各足指に対応する位置を覆う、足幅方向に延びる帯状の部材から構成されている。
この場合には、請求項3の発明と同様に、足の背屈時に各足指がアッパー本体に接触したとき、足指圧接部材の周囲のアッパー本体の伸長量を抑制して、足指圧接部材から足の各足指に作用する圧力を大きめに調整でき、その結果、足指の感覚が鈍くなった高齢者やリハビリの患者に好適のアッパー構造を実現できる。
請求項6の発明では、請求項1において、足指圧接部材が、足の足指の先端に対応する位置に設けられている。
この場合、シューズ着用者は、足の背屈時には、足指の先端でアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。
請求項7の発明では、請求項1において、足指圧接部材が、足の少なくとも第1趾の末節骨および基節骨骨頭部、ならびに第2趾の末節骨骨底部および中節骨を覆う位置に配置されている。
この場合、シューズ着用者は、足の背屈時には、主に第1趾末節骨および基節骨骨重部ならびに第2趾末節骨骨底部および中節骨でアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。
請求項8の発明では、請求項1において、足指圧接部材が、アッパー本体よりも高硬度の材料から構成されている。
この場合、足の背屈時には、足指がアッパー本体に接触したとき、非伸縮性の高硬度材料からなる足指圧接部材が足指に上方から接触するが、このとき、足指圧接部材が硬いため、足指に強く圧接し、これにより、着用者は、足の足指がアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できる。
請求項9の発明では、請求項1において、足指圧接部材が、アッパー本体よりも高剛性の材料から構成されている。
この場合、足の背屈時には、足指がアッパー本体に接触したとき、非伸縮性の高剛性材料からなる足指圧接部材が足指に上方から圧接するが、このとき、足指圧接部材が伸びにくいため、足指に強く圧接し、これにより、着用者は、足の足指がアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できる。
請求項10の発明では、請求項1において、足指圧接部材が、アッパー本体の表面上に固着されている。また、請求項11の発明では、請求項1において、足指圧接部材が、アッパー本体の表面と裏面との間に介装されている。
これらいずれの場合であっても、足指圧接部材は、アッパー本体の裏面には設けられないので、足の背屈時に着用者の足指が足指圧接部材に直接接触することはなく、これにより、背屈時に着用者が違和感や苦痛を覚えたり、足指にマメができたりするのを防止できる。
請求項12の発明では、請求項1において、アッパー本体の先端部には、補強部材が取り付けられており、足指圧接部材は補強部材から分離して設けられている。
この場合には、補強部材によりアッパー本体先端部の摩耗を防止できるばかりでなく、足指圧接部材の周囲が伸縮性アッパー本体で囲繞されていることにより、足の背屈時に足指がアッパー本体に接触したとき、足指圧接部材周囲のアッパー本体が伸長することで、足および足指の背屈の動きがアッパー本体により阻害されることなく、足の背屈運動を促進でき、足指圧接部材が足の足指に必要以上に圧力を及ぼすのを防止できる。
以上のように、本発明に係るシューズ用アッパー構造によれば、足の少なくともつま先部を覆う伸縮性材料製のアッパー本体と、足の足指に対応する位置に設けられかつ周囲がアッパー本体により囲繞されるとともに、足の背屈時に足指に対して上方から圧接する非伸縮性材料製の足指圧接部材とを設けるようにしたので、足の背屈時には、足指がアッパー本体に接触したとき、非伸縮性材料から構成された足指圧接部材が足指に上方から圧接し、これにより、着用者は、足の足指がアッパー本体に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できるようになる。
しかも、この場合には、足指圧接部材の周囲が、伸縮性を有するアッパー本体により囲繞されていることにより、足の背屈時に足指がアッパー本体に接触したとき、足指圧接部材の周囲のアッパー本体が伸長することで、足および足指の背屈の動きがアッパー本体により阻害されることなく、足指がアッパー本体に接触している時間を長くして、足の背屈運動を促進できるとともに、足指圧接部材が足の足指に必要以上に圧力を及ぼすのを防止できるようになる。
The upper structure for shoes according to the invention of
According to the invention of
Further, at the time of dorsiflexion of the foot, when the toe comes into contact with the upper body, the toe pressure contact member made of a non-stretchable material comes into pressure contact with the toe from above. Thus, the wearer can recognize that the toes of the foot have contacted the upper body, and can feel that the dorsiflexion motion of the foot has been properly performed. As a result, the wearer can activate the movement of the foot and toes.
Moreover, in this case, the toe pressure contact member is surrounded by the elastic upper body, so that when the toe comes into contact with the upper body during dorsiflexion of the foot, By extending the upper body of the foot, the dorsiflexion movement of the foot and toes is not obstructed by the upper body, and the time during which the toes are in contact with the upper body is lengthened, and the dorsiflexion movement of the feet is performed. It can be promoted, and the toe pressure contact member can be prevented from applying more pressure than necessary to the toes of the foot.
Incidentally, in FIGS. 1 and 2 of Japanese Utility Model Publication No. 4-18405, a plurality of toe core members (4, 5) are laminated on the inner surface of the toe portion (2) of the shoe upper (1). Are listed.
However, in this case, since the tip edge of the toe core extends to the tip of the sole, when the toes contact the toe core during dorsiflexion of the foot, the shoe upper around the toe core is It can hardly stretch, and the dorsiflexion movement of the foot and toes will be hindered by the shoe upper. In addition, at this time, the toe core member exerts an unnecessarily large pressure on the toes of the foot, which gives a feeling of discomfort and pain to the shoe wearer.
Further, in FIGS. 1 to 5 of Japanese Utility Model Publication No. 6-49205, a toe reinforcement member (5) is provided on a toe portion (4) of an upper member (2) of a sports shoe (1). Are listed. The toe reinforcing member (5) has a main body portion (5a) and a reinforcing member (5b) disposed thereon.
However, in this case, since the tip edge portion of the toe reinforcing member is connected to the sole tip portion (see FIG. 5 of the above publication), when the toes contact the toe portion during dorsiflexion of the foot, The upper member around the reinforcing member can hardly extend, and the dorsiflexion movement of the foot and toes is inhibited by the upper member. Further, at this time, the toe reinforcement member exerts an unnecessarily large pressure on the toes of the foot, which gives the shoe wearer a sense of incongruity and pain.
On the other hand, in the invention of
According to a second aspect of the present invention, in the first aspect, the toe pressure contact member is composed of a plurality of members arranged at positions corresponding to the respective toes of the foot.
In this case, when each toe touches the upper body during dorsiflexion of the foot, each toe pressure contact member made of a non-stretchable material comes into pressure contact with each corresponding toe from above. Thereby, the wearer can recognize that each toe of the foot has contacted the upper body, and can feel that the dorsiflexion motion of the foot has been properly performed. As a result, the wearer can activate the movement of the foot and each toe.
According to a third aspect of the present invention, in the second aspect, the plurality of members are connected to each other via connecting portions provided between adjacent members.
In this case, each member constituting the toe pressure contact member is connected via the connecting portion, so that when the toes contact the upper body at the time of dorsiflexion of the foot, the upper body around each member It is possible to adjust the pressure acting on each toe of the foot from the toe pressure contact member to be large. As a result, it is possible to realize an upper structure that is suitable for elderly people who have become dull in toes or rehabilitation patients.
According to a fourth aspect of the present invention, in the second aspect, the plurality of members are provided separately from each other.
In this case, each member constituting the toe pressure contact member is surrounded by a stretchable upper body, so that when each toe comes into contact with the upper body during foot dorsiflexion, each member The upper body around each can be independently extended, and as a result, the dorsiflexion movement of each toe can be further promoted.
According to a fifth aspect of the present invention, in the first aspect, the toe pressure contact member is composed of a belt-like member extending in the foot width direction that covers a position corresponding to each toe of the foot.
In this case, as in the third aspect of the invention, when each toe touches the upper body during dorsiflexion of the foot, the amount of extension of the upper body around the toe pressure contact member is suppressed, and the toe pressure contact is achieved. The pressure acting on each toe of the foot from the member can be adjusted to be large, and as a result, it is possible to realize an upper structure suitable for an elderly person or a rehabilitation patient who has a dull sense of toes.
According to a sixth aspect of the present invention, in the first aspect, the toe pressure contact member is provided at a position corresponding to the tip of the toe of the foot.
In this case, the shoe wearer can recognize that the tip of the toe has contacted the upper body when the foot is bent back, and can feel that the foot is bent properly.
In a seventh aspect of the present invention, in the first aspect, the toe pressure contact member covers at least the distal phalanx and the proximal phalanx head of the first heel, and the bottom phalanx and the middle phalanx of the second heel. Is arranged.
In this case, when wearing the foot, the shoe wearer can recognize that he / she has contacted the upper body mainly at the first phalanx and proximal phalanx and the second phalanx bottom and middle phalanx. , You can feel that the dorsiflexion of the foot was done properly.
According to an eighth aspect of the present invention, in the first aspect, the toe pressure contact member is made of a material having a hardness higher than that of the upper body.
In this case, at the time of dorsiflexion of the foot, when the toe touches the upper body, the toe pressure contact member made of a non-stretchable high-hardness material comes into contact with the toe from above. Since it is hard, it is strongly pressed against the toes, so that the wearer can recognize that the toes touched the upper body, and can feel that the dorsiflexion movement of the feet has been properly performed. As a result, the wearer can activate the movement of the foot and toes.
According to a ninth aspect of the present invention, in the first aspect, the toe pressure contact member is made of a material having higher rigidity than the upper main body.
In this case, at the time of dorsiflexion of the foot, when the toes touch the upper body, the toe pressure contact member made of a non-stretchable high-rigid material presses against the toes from above. Since it is difficult to stretch, the toe is pressed strongly against the toes, and thus the wearer can recognize that the toes of the toes are in contact with the upper body, and can feel that the dorsiflexion movement of the toes has been properly performed. As a result, the wearer can activate the movement of the foot and toes.
According to a tenth aspect of the present invention, in the first aspect, the toe pressure contact member is fixed on the surface of the upper body. According to an eleventh aspect of the present invention, in the first aspect, the toe pressure contact member is interposed between the front surface and the back surface of the upper main body.
In either case, since the toe pressure contact member is not provided on the back surface of the upper body, the wearer's toe does not directly contact the toe pressure contact member when the foot is dorsiflexed. Thus, it is possible to prevent the wearer from feeling uncomfortable or painful when the dorsiflexion occurs, or to make a leg on the toe.
According to a twelfth aspect of the present invention, in the first aspect, a reinforcing member is attached to the tip of the upper body, and the toe pressure contact member is provided separately from the reinforcing member.
In this case, the reinforcing member can not only prevent the tip of the upper body from being worn, but also the toe pressure contact member is surrounded by the elastic upper body, so that the toe can be The upper body around the toe pressure contact member extends when it touches the foot, and the dorsiflexion movement of the foot and toes can be promoted without being hindered by the upper body. It is possible to prevent the member from exerting an excessive pressure on the toes of the foot.
As described above, according to the upper structure for shoes according to the present invention, the upper body made of a stretchable material that covers at least the toe portion of the foot, the position corresponding to the toes of the foot, and the periphery is formed by the upper body. A toe pressure contact member made of a non-stretch material that is pressed against the toes from above when the foot is bent back is provided, so that the toes touch the upper body when the foot is bent back When the toe is pressed against the toes from above, the wearer can recognize that the toes contacted the upper body, and the dorsiflexion of the toes You can feel that exercise was done properly. As a result, the wearer can activate the movement of the foot and toes.
In addition, in this case, when the toe touches the upper body when the foot is dorsiflexed, the circumference of the toe pressure contact member is surrounded by the elastic upper body. By extending the upper body of the foot, the dorsiflexion movement of the foot and toes is not obstructed by the upper body, and the time during which the toes are in contact with the upper body is lengthened, and the dorsiflexion movement of the feet is performed. In addition to being able to promote, it is possible to prevent the toe pressure contact member from applying more pressure than necessary to the toes of the foot.

以下、本発明の実施例を添付図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
第1図ないし第5B図は、本発明の第1の実施例によるアッパー構造を説明するための図であって、これらの図において、同一符号は同一または相当部分を示している。
第1図および第2図に示すように、シューズ1は、ソール2と、ソール2の上に設けられ、その下部がソール2に固着された、着用者の足Pを覆うアッパー(アッパー本体)3とを備えている。なお、シューズ1の踵部から中足部にかけて、アッパー3の下部には、補強部材10が設けられている。また、第1図中、参照符号12は舌革部を、参照符号13は靴紐を示している。
アッパー3は、例えばメッシュ素材のような伸縮性材料から構成されている。また、アッパー3は、スパンデックスのような弾性繊維を含む伸縮性材料から構成されていてもよい。ここで、スパンデックスとは、ポリウレタンを溶剤に溶かして紡糸した弾性繊維のことである。
アッパー3の表面(つまり表材の外表面)において足Pの各足指に対応する位置には、非圧縮性材料からなる足指圧接部材4が固着されている。ここでは、足指圧接部材4は、足Pの各足指の先端に対応する位置に配置されている。足指圧接部材4は、具体的には、天然皮革、合成皮革、人工皮革、ポリウレタンまたはラバー等から構成されている。足指圧接部材4は、アッパー3よりも高硬度または高剛性の部材から構成されているのが好ましい。
足指圧接部材4は、足Pの各足指(好ましくはその先端)に対応する位置に配置された5個の圧接部41~45と、隣り合う各圧接部の間を連結する4個の連結部40とから構成されている。
足指圧接部材4は、好ましくは、足Pの少なくとも第1趾の末節骨DP1および基節骨PP1骨頭部、ならびに第2趾の末節骨DP2骨底部および中節骨MP2を覆う位置に配置されている。この例では、足指圧接部材4は、さらに第3趾の末節骨DP3および中節骨MP3骨頭部、第4趾の末節骨DP4および中節骨MP4骨頭部、第5趾の末節骨DP5および中節骨MP5に対応する位置に配置されている。なお、第2図中、DPは末節骨を、MPは中節骨を、PPは基節骨を、MBは中足骨を、MJは中足趾節関節をそれぞれ示しており、添え字の1~5はそれぞれ第1趾~第5趾を示している。
また、足指圧接部材4の周囲は、アッパー3により囲繞されている。つまり、足指圧接部材4は、シューズ先端の外周縁部に配設されたソール2に連結されることなく、ソール2から分離して設けられている。
次に、アッパーが天然皮革のみから構成されたシューズと、アッパーがメッシュ素材のみから構成されたシューズと、本実施例によるアッパー構造を有するシューズの3種類のシューズを用意し、それぞれ被験者に履いてもらって歩行試験を行った。
この試験では、まず、第3図に示すように、被験者の足Pの表面上において第1趾~第5趾に対応する位置に各足指に沿って帯状の圧力センサ51~55を貼り付けた。被験者は、その上から靴下を履き、各シューズを着用した。また、歩行試験は、時速5kmで6秒間行った。
第4A~4C図は、圧力センサにより測定された荷重(Load)の時間的変化を示すグラフである。これらの図において、第4A図はアッパーが天然皮革のみから構成されたシューズの場合を、第4B図はアッパーがメッシュ素材のみから構成されたシューズの場合を、第4C図は本実施例によるアッパー構造を有するシューズの場合をそれぞれ示している。圧力センサが荷重を検知するのは、足および足指が背屈して足指(したがって圧力センサ)がアッパー裏面に接触したときであり、足指がアッパー裏面に強く当たるほど、荷重のピーク値は高くなり、足指がアッパー裏面に長く当たっているほど、荷重の作用時間は長くなる。
第4A図に示すように、アッパーが非伸縮性の天然皮革のみから構成されたシューズの場合には、荷重のピーク値は高いが、荷重の作用時間(つまり足指の接触時間)は短くなっていることが分かる。これは、天然皮革製のアッパー材は硬く、足当たりが強いため、荷重のピークは出やすいが、アッパー材が伸びにくいことで、足指が背屈しにくいため、足指の背屈状態を維持しにくくなっていると考えられる。したがって、この場合には、足指の自由な背屈運動が制限されているといえる。
第4B図に示すように、アッパーが伸縮性のメッシュ素材のみから構成されたシューズの場合には、荷重の作用時間(足指の接触時間)は長いが、荷重のピーク値は低くなっていることが分かる。これは、メッシュ素材のアッパー材は柔らかく、足指が背屈しやすいため、足指の背屈状態を維持しやすくなっているが、足指の接触時にアッパー材が伸びることで、荷重のピークが低くなると考えられる。したがって、この場合には、足指の自由な背屈運動は可能であるが、足指が背屈を感知しにくくなっているといえる。
第4C図に示すように、本実施例によるアッパー構造を有するシューズの場合には、荷重のピーク値は高く、荷重の作用時間(足指の接触時間)も長くなっていることが分かる。
これは、足指の背屈時には、足指が足指圧接部材4に対してアッパー裏面側から押接し、このとき、足指圧接部材4が非伸縮性材料(または高剛性材料)から構成されていることで、足指圧接部材4が伸びにくくなっており、これにより、足指圧接部材4が足指(圧力センサ)に圧接して、荷重のピークが出やすくなっていると考えられる。また、足指圧接部材4が高硬度材料から構成されている場合には、足指圧接部材4が硬く、足当たりが強いため、足指の背屈時に荷重のピークが出やすくなっていると考えられる。
その一方、足指圧接部材4が伸縮性材料製のアッパー3に囲繞されていることで、足指の背屈時に足指が足指圧接部材4に対してアッパー裏面側から圧接したとき、足指圧接部材4の周囲のアッパーが伸びることで、足指が背屈しやすくなっており、これにより、足指の背屈状態を維持しやすくなっていると考えられる。
したがって、この場合には、足指の自由な背屈運動を維持しつつ、足指が背屈を感知しやすくなっているといえる。
次に、足および足指の背屈運動を検証するために、ランニング試験中に被験者の前脛骨筋の筋電図を測定した。ここで、前脛骨筋とは、脛骨の外側から足甲内側に繋がる筋肉であって、足および足指の背屈運動時に作用する筋肉である。
この試験では、まず、被験者の脚の前脛骨筋に対応する位置に電極を貼り付け、ランニング中の被験者の前脛骨筋の筋電位を測定した。なお、ランニング試験は、時速10kmで行った。
第5A~5B図は、ランニング試験における筋電図である。第5A図は被験者が素足で走行した場合を、第5B図は被験者が本実施例によるシューズを着用して走行した場合をそれぞれ示している。これらの図において、縦軸は筋電位を示しており、横軸の0は接地時点を、0.3が離地時点を、−0.1付近は接地前の遊脚期をそれぞれ示している。また、各図中、筋電位の発生は、前脛骨筋が働いていることを示している。
第5A図および第5B図のいずれの場合においても、接地前の遊脚期(横軸の−0.1付近)から接地時点(横軸の0の位置)にかけての足および足指の背屈局面において、高い筋電位が発生しており、被験者の足および足指の背屈運動が行われていることが分かる。
また、第5A図および第5B図を比較すると分かるように、被験者が本実施例によるシューズを着用して走行した第5B図の場合の方が、被験者が素足で走行した第5A図の場合よりも、接地前の遊脚期(横軸の−0.1付近)から接地時点(横軸の0の位置)にかけての背屈局面において発生する筋電位の値が大きくなっている。したがって、この背屈局面において筋電位の値を積分したとき、その積分値は第5B図の方が第5A図よりも大きい。このように、筋電位の積分値の大きい方が筋活動が活発に行われたことを示している。したがって、本実施例によるアッパー構造を有するシューズを着用して走行すると、素足で走行する場合よりも、前脛骨筋の活動が活発になり、足および足指の背屈運動が活発に行われるようになったことが分かる。
以上のことから、本実施例によるアッパー構造によれば、足の背屈時に第1趾~第5趾のすべてまたはいずれかの足指(またはその先端部)がアッパー3の裏面に接触したとき、非伸縮性材料から構成された足指圧接部材4が足指(またはその先端部)に上方から圧接する。これにより、着用者は、足の足指がアッパー3に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できる。
このとき、足指圧接部材4がアッパー3よりも高硬度(または高剛性)の材料から構成されている場合には、足の背屈時に足指がアッパー3に接触したとき、足指圧接部材4が足指に上方から接触するが、このとき、足指圧接部材4が硬い(または伸びにくい)ため、足指に強く圧接し、これにより、着用者は、足の足指がアッパー3に接触したことを認識でき、足の背屈運動が適正に行われたことを実感できる。その結果、着用者は、足および足指の動きを活性化できる。
しかも、この場合には、足指圧接部4材の周囲が、伸縮性を有するアッパー3により囲繞されていることにより、足の背屈時に足指がアッパー3に接触したとき、足指圧接部材4の周囲のアッパー3が伸長することで、足および足指の背屈の動きがアッパー3により阻害されることなく、足指がアッパー3に接触している時間を長くして、足の背屈運動を促進できるとともに、足指圧接部材4が足の足指に必要以上に圧力を及ぼすのを防止できる。
また、この場合には、足指圧接部材4を構成する各圧接部41~45が連結部40を介して互いに連結されていることにより、足の背屈時に各足指がアッパー3に接触したとき、各圧接部41~45の周囲のアッパー3の伸長量を抑制して、足指圧接部材4から足の各足指に作用する圧力を大きめに調整できる。その結果、足指の感覚が鈍くなった高齢者やリハビリの患者に好適のアッパー構造を実現できる。
なお、この場合には、アッパー3が伸縮性材料から構成されていることで、足の底屈時につま先部が屈曲する際にも、アッパー3が伸縮することで、足および足指の底屈の動きがアッパー3により阻害されることなく、足の底屈運動を促進できる。
1 to 5B are views for explaining an upper structure according to the first embodiment of the present invention. In these drawings, the same reference numerals indicate the same or corresponding parts.
As shown in FIGS. 1 and 2, a
The upper 3 is made of a stretchable material such as a mesh material. Further, the upper 3 may be made of a stretchable material including elastic fibers such as spandex. Here, spandex is an elastic fiber obtained by spinning polyurethane in a solvent.
A toe

The toe
Further, the periphery of the toe
Next, three types of shoes are prepared: a shoe in which the upper is composed only of natural leather, a shoe in which the upper is composed only of a mesh material, and a shoe having an upper structure according to this embodiment. A gait test was conducted.
In this test, first, as shown in FIG. 3, belt-
4A to 4C are graphs showing temporal changes in the load (Load) measured by the pressure sensor. In these drawings, FIG. 4A shows the case where the upper is made only of natural leather, FIG. 4B shows the case where the upper is made only of mesh material, and FIG. 4C shows the upper according to this embodiment. Each case of a shoe having a structure is shown. The pressure sensor detects the load when the foot and toes are bent back and the toes (and hence the pressure sensor) touch the upper back surface. The longer the toes hit the back of the upper, the longer the load action time.
As shown in FIG. 4A, in the case of a shoe whose upper is composed only of non-stretchable natural leather, the load peak value is high, but the load application time (that is, the toe contact time) is shortened. I understand that This is because the upper material made of natural leather is hard and has a strong foot contact, so the peak of the load tends to occur, but the upper material is difficult to stretch, so the toes are difficult to dorsiflex, so the toes are kept bent back It seems to be difficult to do. Therefore, in this case, it can be said that the free dorsiflexion movement of the toes is limited.
As shown in FIG. 4B, in the case of a shoe whose upper is composed only of a stretchable mesh material, the load application time (toe contact time) is long, but the load peak value is low. I understand that. This is because the mesh upper material is soft and the toes are prone to dorsiflexion, making it easy to maintain the dorsiflexion state of the toes, but the upper material stretches when the toes contact, causing a load peak. It is thought to be lower. Therefore, in this case, the toes can be freely dorsiflexed, but it can be said that the toes are difficult to detect dorsiflexion.
As shown in FIG. 4C, in the case of the shoe having the upper structure according to the present example, it can be seen that the peak value of the load is high and the load application time (toe contact time) is also long.
This is because when the toes are dorsiflexed, the toes press against the
On the other hand, when the toe
Therefore, in this case, it can be said that the toes can easily detect dorsiflexion while maintaining free dorsiflexion motion of the toes.
Next, in order to verify the dorsiflexion of the foot and toes, electromyograms of the subject's anterior tibial muscle were measured during the running test. Here, the anterior tibial muscle is a muscle that is connected from the outside of the tibia to the inside of the instep and that acts during dorsiflexion of the foot and toes.
In this test, an electrode was first attached at a position corresponding to the anterior tibial muscle of the subject's leg, and the myoelectric potential of the anterior tibial muscle of the subject during running was measured. The running test was conducted at 10 km / h.
5A to 5B are electromyograms in the running test. FIG. 5A shows a case where the subject runs with bare feet, and FIG. 5B shows a case where the subject runs while wearing the shoes according to this embodiment. In these figures, the vertical axis indicates myoelectric potential, 0 on the horizontal axis indicates the time of ground contact, 0.3 indicates the time of takeoff, and the vicinity of -0.1 indicates the swing leg period before ground contact. . In each figure, the generation of myoelectric potential indicates that the anterior tibial muscle is working.
In both cases of FIG. 5A and FIG. 5B, the dorsiflexion of the foot and toes from the swing leg period (around −0.1 on the horizontal axis) to the time of contact (
Further, as can be seen by comparing FIG. 5A and FIG. 5B, the case of FIG. 5B in which the subject runs while wearing the shoes according to this example is more than the case of FIG. 5A in which the subject runs with bare feet. In addition, the value of the myoelectric potential generated in the dorsiflexion phase from the swing leg period (around −0.1 on the horizontal axis) to the time of ground contact (
From the above, according to the upper structure according to the present embodiment, when all or any of the first to fifth heels (or the tip thereof) contact the back surface of the upper 3 when the foot is bent back. The toe
At this time, when the toe
In addition, in this case, the toe
Further, in this case, the respective
In this case, since the upper 3 is made of an elastic material, the upper 3 expands and contracts even when the toe portion bends when the foot is bent, so The movement of the leg can be promoted without hindering the upper 3 from moving.
前記第1の実施例では、足指圧接部材4を構成する圧接部として、5個の圧接部41~45が設けられた例を示したが、本発明の適用はこれに限定されない。例えば、圧接部として、足の第1趾に対応する位置にのみ配置されたただ一つの圧接部や、第1趾および第2趾に対応する位置に配置された2個の圧接部、第1趾ないし第3趾に対応する位置に配置された3個の圧接部、または第1趾ないし第4趾に対応する位置に配置された4個の圧接部を用いるようにしてもよい。なお、圧接部を配置する足指の例としては、これらの例には限定されない。
これらいずれの場合においても、シューズ着用者は、圧接部が設けられた位置に対応する足指により、足および足指の背屈運動を認識できることになる。
In the first embodiment, the example in which the five
In any of these cases, the shoe wearer can recognize the dorsiflexion motion of the foot and toes by the toes corresponding to the positions where the press contact portions are provided.
前記第1の実施例では、足指圧接部材4が、足の各足指に対応する位置に配置された5個の圧接部41~45と、隣り合う各圧接部の間を連結する連結部40とから構成された例を示したが、本発明の適用はこれには限定されず、連結部を省略することにより、各圧接部41~45を互いに分離して設けるようにしてもよい。
この場合には、足指圧接部材4を構成する各圧接部41~45の周囲が、伸縮性を有するアッパー3により囲繞されていることにより、足の背屈時に各足指がアッパー3に接触したとき、各圧接部41~45の周囲のアッパー3がそれぞれ独立して伸長することができ、その結果、各足指の背屈運動を一層促進できるようになる。
In the first embodiment, the toe
In this case, the circumference of each of the
第6図および第7図は、本発明の第4の実施例によるアッパー構造を説明するための図であって、これらの図において、前記第1の実施例と同一符号は同一または相当部分を示している。
この第4の実施例では、足指圧接部材4’が、足の各足指の先端に対応する位置を帯状(この例では弧状)に覆う部材から構成されている。具体的には、足指圧接部材4は、足Pの第1趾の末節骨DP1、第2趾の末節骨DP2骨底部および中節骨MP2、第3趾の末節骨DP3および中節骨MP3骨頭部、第4趾の末節骨DP4および中節骨MP4骨頭部、第5趾の末節骨DP5に対応する位置に配置されている。
また、この場合においても、前記第1の実施例と同様に、アッパー3は伸縮性材料から構成され、足指圧接部材4’は非伸縮性材料から構成されており、足指圧接部材4’の周囲は、アッパー3により囲繞されている。また、シューズ1の先端部には、補強部材11が設けられており、補強部材11は、シューズ先端のソール2に固着されている。足指圧接部材4は、補強部材11からも分離して設けられている。
この場合には、足および足指の背屈時に各足指がアッパー3に接触したとき、足指圧接部材4’の周囲のアッパー3の伸長量を抑制して、足指圧接部材4’から足の各足指に作用する圧力を大きめに調整でき、その結果、足指の感覚が鈍くなった高齢者やリハビリの患者に好適のアッパー構造を実現できる。
しかも、この場合には、補強部材11によりアッパー3先端部の摩耗を防止できるばかりでなく、足指圧接部材4’が補強部材11から分離されて足指圧接部材4’の周囲が伸縮性アッパー3で囲繞されていることにより、足の背屈時に足指がアッパー3の裏面に接触したとき、足指圧接部材4’周囲のアッパー3が伸長することで、足および足指の背屈の動きがアッパー3により阻害されることなく、足の背屈運動を促進でき、足指圧接部材4’が足の足指に必要以上に圧力を及ぼすのを防止できる。
FIGS. 6 and 7 are views for explaining an upper structure according to a fourth embodiment of the present invention. In these drawings, the same reference numerals as those in the first embodiment denote the same or corresponding parts. Show.
In the fourth embodiment, the toe
Also in this case, as in the first embodiment, the upper 3 is made of a stretchable material, the toe
In this case, when each toe touches the upper 3 at the time of dorsiflexion of the foot and toes, the extension amount of the upper 3 around the toe
In addition, in this case, not only the
前記第1ないし第4の実施例では、足指圧接部材4、4’がアッパー3の表面(表材の外表面)に設けられた例を示したが、本発明の適用はこれに限定されない。足指圧接部材4、4’は、アッパー3の表面と裏面との間(つまり表材と裏材との間の内装材)に設けられていてもよい。
この場合においても、足指圧接部材4、4’は、アッパー3の裏面には設けられていないので、足の背屈時に着用者の足指が足指圧接部材4、4’に直接接触することはなく、これにより、背屈時に着用者が違和感や苦痛を覚えたり、足指にマメができたりするのを防止できる。
In the first to fourth embodiments, the toe
Also in this case, since the toe
