Description

この発明は、外反母趾対応の履物、更に詳しくは、履いているだけで、縄跳びや爪先立ちの効果が得られ、足裏の横アーチを鍛えることで外反母趾の症状を緩和することができる履物に関する。 The present invention relates to footwear for hallux valgus, and more particularly to footwear that can provide the effect of jumping rope and standing on toes just by wearing it, and can relieve symptoms of hallux valgus by forging a lateral arch on the sole.

足裏には、３つのアーチと呼ばれる弓形のカーブがあり、踵から親指の付け根を通る足の内側の縦アーチと、踵から小指の付け根を通る足の外側の縦アーチと、そして、親指の付け根と小指の付け根を通る横アーチであり、各アーチはそれぞれ板バネのように作用して、足に掛かる力を吸収、分散させるクッションになっている。 There are three arch-shaped curves on the sole of the foot, the vertical arch inside the foot passing from the heel to the base of the thumb, the vertical arch outside the foot passing from the heel to the base of the little finger, and the thumb It is a horizontal arch that passes through the base of the base and the little finger. Each arch acts as a leaf spring, and serves as a cushion that absorbs and disperses the force applied to the foot.

従って、何らかの原因で足のアーチ構造が崩れてしまうと、クッションの効きが悪くなり、荷重のバランスが変わって、足に思わぬ負担が掛かることになり、そして、外反母趾の最大の原因は、上記した足の横アーチの崩れである。 Therefore, if the arch structure of the foot collapses for some reason, the effectiveness of the cushion will deteriorate, the load balance will change, and an unexpected burden will be applied to the foot, and the largest cause of hallux valgus is the above It is the collapse of the horizontal arch of the leg that I did.

図３（ａ）は足Ａに生じた外反母趾の状態を示し、足の横のアーチが崩れて低下したことで、親指の大本の骨と足先の骨が、足指の付け根を境に大きな角度αを作り、親指が２番目の指の下に潜り込んだり上に乗るようになり、２番目や３番目の指の付け根に荷重が掛かって、タコや筋状の角質ができたり、足指に痛みを感じることになり、横アーチを支えなければ症状が悪化することになる。 FIG. 3 (a) shows the state of the hallux valgus that has occurred on the foot A. Since the arch on the side of the foot has collapsed and lowered, the large bone of the thumb and the bone of the toe border the base of the toe. A large angle α is created so that the thumb can sneak under the second finger or ride on it, and a load is applied to the base of the second and third fingers, creating octopus and horny stratum corneum, You will feel pain in your fingers and your symptoms will worsen if you do not support the side arch.

従来、上記外反母趾の症状を緩和する有効な方法として、縄跳びが効果的であることが知られている。縄跳びのメカニズムは、図２（ｂ）のように、足Ａが爪先立ちの状態で着地することになるが、同図右側の着地時の状態から体重を支えるために、同図左側に示すように踵側が高さＨだけ下がることになり、これによって指先に力が加わることになり、このような指先に加わる力によって、図３（ｂ）のように、横のアーチＣを鍛え、足指の付け根を境とする角度が小さくなり、外反母趾対策に効果が得られるものである。 Conventionally, it is known that jumping rope is effective as an effective method for alleviating the symptoms of hallux valgus. As shown in FIG. 2 (b), the skipping mechanism is to land with the foot A standing on the tip of the toe, as shown on the left side of the figure in order to support the weight from the landing state on the right side of the figure. The heel side will be lowered by the height H, and this will apply a force to the fingertip. With such a force applied to the fingertip, the side arch C is forged as shown in FIG. The angle at the base becomes small, and it is effective for measures against hallux valgus.

そこでこの発明は、上記のような縄跳びによる外反母趾対策の効果に着目し、履いて歩くだけで、縄跳びや爪先立ちの効果をえることができ、同時に、開張足の補助と足裏のアーチ補正と衝撃分散の効果によって、横のアーチを支えて鍛えことができる外反母趾対応履物を提供することを課題としている。 Therefore, the present invention pays attention to the effect of the hallux valgus countermeasure by jumping rope as described above, and it is possible to obtain the effect of jumping rope and standing on the toe just by wearing it, and at the same time, assisting the extension leg and correcting the arch of the foot and the impact The object of the present invention is to provide footwear for hallux valgus that can be trained by supporting the side arch by the effect of dispersion.

上記履物台である履物本体は、可撓性のある履物用材料を用い、爪先側に甲皮を設けてサンダルに形成され、踵側は踵後部から爪先側に向けて設けた切り欠きによって上台と下台の上下二又状となり、この上台と下台の対向面間にコイルスプリングを縮設し、踵部分にクッション性を付与していると共に、埋設した弾性板が爪先のローリング運動を補助し、爪先側を上方へ弧状に反り上げたことによりテコの原理が発生し、踵の上下運動と爪先の上下運動の組み合わせで、より縄跳び運動に近い効果が得られることになる。 The footwear body, which is the above footwear table, is made of sandals with a flexible footwear material with a crust on the toe side, and the heel side is formed by a notch provided from the back of the heel toward the toe side. The upper and lower bases have a bifurcated shape, and a coil spring is contracted between the opposing surfaces of the upper and lower bases to provide cushioning to the heel part, and the embedded elastic plate assists the rolling motion of the toes, The lever principle is generated by raising the toe side upward in an arc shape, and an effect closer to a jump rope movement can be obtained by combining the vertical movement of the heel and the vertical movement of the toe.

また、人差し指から小指が納まる凹部は、履物本体を指で掴めるようにし、外反母趾対策に効果をもたせ、上記中足骨サポートは、開張足を抑制するように横のアーチを支えることになる。 In addition, the concave portion in which the little finger is accommodated from the index finger allows the footwear body to be grasped by the finger, which has an effect on the hallux valgus countermeasure, and the metatarsal support supports the lateral arch so as to suppress the extension foot.

更に、上記ヒールカップは、足の踵から両側に伸びるように、内側に傾斜を持たせて設けられ、足裏を定位置に保つと共に、足の接地範囲を広げ、衝撃吸収効果を発揮する。 Further, the heel cup is provided with an inward slope so as to extend from the heel of the foot to both sides, and the sole is kept in a fixed position, and the ground contact range of the foot is widened to exert an impact absorbing effect.

この発明によると、爪先側を反り上げた履物本体の踵側にクッション性を付与したので、爪先側を上方へ弧状に反り上げたことによりテコの原理が発生し、埋設した弾性板が爪先のローリング運動を補助し、踵の上下運動と爪先の上下運動の組み合わせで、より縄跳び運動に近い効果が得られることになり、履いて歩くだけで、外反母趾の症状を緩和することができる。 According to the present invention, since the cushioning property is imparted to the heel side of the footwear body with the toe side warped, the lever principle is generated by raising the toe side upward in an arc shape, and the embedded elastic plate is By assisting the rolling exercise and combining the vertical movement of the heel and the vertical movement of the toes, an effect closer to a jump rope movement can be obtained, and the symptoms of hallux valgus can be alleviated simply by wearing it and walking.

また、この記履物本体の上面に、人差し指から小指が納まる凹部と、開張足を抑制する中足骨サポートと、足のヒールを囲むヒールカップを配置したので、人差し指から小指が凹部で履物本体を掴めることになり、外反母趾対策に効果をもたせ、中足骨サポートは、開張足を抑制するように横のアーチを支えることになり、開張足を補助して横アーチを鍛えることができる。 In addition, on the upper surface of the footwear body, a concave part that fits the little finger from the index finger, a metatarsal support that suppresses the open foot, and a heel cup that surrounds the heel of the foot are placed, so the foot part from the forefinger to the concave part As a result, the metatarsal support supports the lateral arch so as to suppress the extended leg, and the lateral arch can be trained by assisting the extended leg.
