Description
本発明は靴の中敷に関し、詳しくは歩行走行時に足にかかる衝撃を効果的に吸収すると共に足に対するサポート性とフィット感を維持させ、正常歩行を促すようにした靴の中敷に関する。 The present invention relates to a shoe insole, and more particularly to a shoe insole that effectively absorbs an impact on a foot during walking and maintains a foot support and fit and promotes normal walking.
通常、人の歩行走行においては、足の長手方向に沿った内外の２つの縦アーチ、即ち踵骨から第１中足骨頭部へかけての内側アーチと踵骨から第５中足骨頭部にかけての外側アーチと、足の短手方向への２つの横アーチ、即ち第１楔状骨から立方骨の先端にかけて第１の横アーチと、第１中足骨の頭部から第５中足骨の頭部にかけてのボール部で構成される第２の横アーチとで体重負荷のよる着地衝撃圧を吸収しながら歩行走行するものである。 Usually, in human walking, two internal and external longitudinal arches along the longitudinal direction of the foot, that is, the medial arch from the radius to the first metatarsal head and the radius to the fifth metatarsal head The lateral arch of the foot, two transverse arches in the lateral direction of the foot, ie, the first transverse arch from the first wedge bone to the tip of the cubic bone, and the head of the first metatarsal to the fifth metatarsal The second lateral arch composed of a ball portion over the head is used for walking while absorbing landing impact pressure due to weight load.
そして、歩行走行において体重負荷は、まず踵部外側から内側にかけて回内しながら踵部裏面に負荷され、次に踵部裏面から足の長手方向における外不踏部裏面に沿って徐々に前方に向けて回外しながら移動され、第５指のボール部裏面、即ち第５中足骨と第５基節骨との関節部裏面へとローリングしながら地面を踏みつけて移動され、次に第１基節骨と第１末節骨裏面で地面を反らせてピッチングさせながら第１基節骨裏面で地面を把持して第１〜５指、特に１，２，３指で蹴って前進を繰り返しながら歩行走行、所謂「あおり（正常）歩行走行」するものといわれている。 In walking, the weight load is first applied to the back of the buttocks while turning from the outside to the inside of the buttocks, and then gradually forward from the back of the buttocks along the back of the outer tread in the longitudinal direction of the foot. The ball is moved toward the back of the ball part of the fifth finger, that is, moved to the back of the joint part of the fifth metatarsal bone and the fifth proximal phalanx while being stepped on the ground. While walking and pitching the phalange and the back surface of the first distal phalanx, the ground is gripped by the back surface of the first basic phalange and kicked with the 1st to 5th fingers, especially 1, 2 and 3 fingers. It is said to be a so-called “aori (normal) walking”.
一方、足底アーチの発達については、３歳ごろには骨格自体のアーチ構造は存在しており、成長に伴い８、９歳ごろには成人の足と同様に足アーチが外見上確認できるようになる。また骨の成長は新生児の足をＸ線でみると趾骨、中足骨の骨幹部、距骨と踵骨の核がみえ、残る大部分の骨は軟骨の状態であり、これらが互いに腱や靭帯で緩く連結されている状態である。その後、距骨と踵骨の２つだけが骨化し、その後立方骨、３つの楔状骨そして最後に舟状骨(４−５歳)が骨化するといわれている。歩行開始後から５、６歳にかけてはしっかりとした足の発達、成長していく時期であり、活動性を高めるには靴の中敷が重要である。 On the other hand, with regard to the development of plantar arches, the arch structure of the skeleton itself exists around the age of 3, and with the growth, the foot arches can be visually confirmed around the age of 8 and 9 like adult feet. become. Bone growth can be seen in X-rays of the newborn's feet, with the ribs, metatarsal shafts, talus and fibula nuclei, and most of the remaining bones in the cartilage state, which are tendons and ligaments. It is in a state where it is loosely connected. After that, it is said that only the talus and ribs become ossified, and then the cuboid, the three wedges, and finally the scaphoid (4-5 years old). From the start of walking to the age of 5 and 6 years, it is a time when the foot develops and grows firmly, so insole is important for enhancing activity.
ところが、従来の靴中敷は、通常子供用の中敷として、装着や洗濯し易いように比較的厚みの薄い中敷が一般使用されており、足に対するサポート性やフィット性が備えられていない。そこで、それらを改良する中敷として、あおり歩行、歩行走行安定性、衝撃吸収性、フィット性を向上させるために、踵部から不踏部にかけて立設した半中敷状のスタビライザーを中敷本体に装着したものが提案されている。 However, conventional insoles are usually used as insoles for children, so that insoles with a relatively thin thickness are generally used so that they are easy to put on and wash. . Therefore, as an insole to improve them, a semi-sole-like stabilizer standing from the buttocks to the treads in order to improve tilt walking, walking running stability, shock absorption, and fitability It has been proposed to be attached to.
例えば、その中敷本体の踵部から不踏部下面にかけて半敷状のスタビライザーを装着した中敷では、そのスタビライザーの踵中央部に打ち抜き部が、内アーチ部側の外側壁に複数のテーパー状の打ち抜きが、外アーチ部に三ヶ月乃至半月状の打ち抜き部が形成され、これらの打ち抜き部にクッション性の中敷本体が露出充填され、しかも足の第１指から第２指のボールジョイント部に対応する中敷本体の踏み付け部に凹みが設けられているものが開示されている。（特許文献１） For example, in an insole where a half-sleeve stabilizer is mounted from the buttock of the insole body to the underside of the treadle, the punched part is at the center of the heel of the stabilizer, and the outer wall on the inner arch part side is tapered. The outer arch part is formed with a three-month to half-moon shaped punch part, and a cushioning insole body is exposed and filled in the punch part, and the ball joint part of the foot from the first finger to the second finger What is provided with the dent in the stepping part of the insole main body corresponding to is disclosed. (Patent Document 1)
しかしながら、従来技術の前記中敷を装着した靴を履いて歩行した場合、歩行走行において体重負荷は、まず踵部において外側が着地した際、中敷本体の踵がスタビライザーの外側壁並びに底部外周辺で拘束され踵部は回内し踵部中央へ移動され、その後体重負荷は踵部裏面から足の長手方向における外不踏部裏面に沿って徐々に前方に向けて回外しながら移動され、第５指のボール部裏面、即ち第５中足骨と第５基節骨との関節部裏面へとローリングしながら地面を踏みつけて移動され、次に第１基節骨と第１末節骨裏面で地面を反らせてピッチングとなるが、スタビライザーの前縁が足底縦軸に対し外向きに傾斜し内側不踏部からそれより斜め後方の外側不踏部に至る形状であるので、その前縁を軸に踏み付け部が屈曲して爪先より外向きに蹴り出されるため過度に回外しがちになる。このため骨が完成されていない成長期の子供においては体重移動が第1指ボールポイントへ誘導しずらくなるため、「あおり歩行走行」が行われにくいことが判明した。 However, when walking with the shoes equipped with the insole of the prior art, the weight load in walking running is that when the outer side first lands on the heel part, the heel of the insole body is the outer wall of the stabilizer and the outer periphery of the bottom part. The hips are constrained and moved to the center of the buttocks, and the weight load is then moved from the back of the buttocks along the back of the outer tread in the longitudinal direction of the foot while gradually unfolding forward. It is moved by stepping on the ground while rolling to the back of the ball part of five fingers, that is, the joint back of the fifth metatarsal bone and the fifth proximal phalanx. Pitching is caused by warping the ground, but the front edge of the stabilizer is inclined outward with respect to the vertical axis of the sole and extends from the inner treadle to the outer treadle that is diagonally behind it. The stepping part is bent to the shaft and outwards from the toes Kicking excessively become Kaihazushi tend order is Desa in. For this reason, it has been found that in a growing child whose bones are not completed, it is difficult to perform “walking and walking” because weight shift is difficult to guide to the first finger ball point.
また、前記スタビライザーは、その内側アーチ部の外側壁には複数のテーパー状の打ち抜き部が形成されているが、他の骨より外側に突出した舟状骨の位置では皮下組織が薄いためそこに打ち抜き部が当接されると違和感を受け易く、また外側アーチ部には半月状の打ち抜き部が形成されているが当該内側アーチ部の外側壁の打ち抜き部に対応していないため、足の発達時の子供靴においては足に対してのフィット感やサポート性について不十分であった。 Further, the stabilizer has a plurality of tapered punched portions formed on the outer wall of the inner arch portion, but the subcutaneous tissue is thin at the position of the scaphoid bone protruding outward from the other bones. It is easy to feel uncomfortable when the punched part comes into contact, and the outer arch part has a half-moon shaped punched part, but it does not correspond to the punched part of the outer wall of the inner arch part. The children's shoes at that time were insufficient in terms of fit and support for the feet.
そして、中敷本体においては、その上面が踵部から爪先に至って漸次低く形成された形状からなるため、歩行中に足がずれ前方へ移動したりして、しっかりとした歩行走行動作が行われにくかった。 In the insole body, the upper surface has a shape that gradually decreases from the buttocks to the toes. It was difficult.
そこで、本発明の靴の中敷は、このような従来事情を鑑みたもので、その目的は踵部での着地安定性や衝撃吸収性を向上させると共に、足の骨格に適して足に対するサポート性とフィット感を維持させ、蹴り出す段階においてより体重移動をコントロールすることによりあおり（正常）歩行を促すようにした靴中敷を提供することにある。 Therefore, the insole of the shoe of the present invention is in consideration of such conventional circumstances, and its purpose is to improve landing stability and shock absorption at the buttock and to support the foot suitable for the skeleton of the foot. An object is to provide a shoe insole that maintains a sex and a fit, and controls the movement of weight more in the kicking out stage to promote a normal (normal) walking.
本発明の靴の中敷は、上面に上張りを設けたクッション性の中敷本体と、その中底本体の不踏部から踵部に至る下面に硬質プレートを有した靴の中敷であって、該中敷本体の上面を不踏部から踵部にかけて周縁部を足裏に沿って高く肉厚に形成して内側アーチサポートと外側アーチサポートと踵サポートとを設けると共に踵部上面に球面状の窪みを形成し、また該硬質プレートにおいてはその踵中央部に切欠き部が形成されると共に踵外周壁に沿って踵補強壁を、内側アーチ側と外側アーチ側とには対向して内側補強壁、外側補強壁を形成すると共にその前縁を第１指ボールジョイント部と踵部中心とを結ぶ軸線に対して第１中足骨の底部からほぼ直交し第５中足骨に至る幅とした形状にした。The insole of the present invention is a shoe insole having a cushioned insole body provided with an upper surface on the upper surface and a hard plate on the lower surface from the non-stepped part of the insole body to the buttocks. The upper surface of the insole body is formed from a non-stepped portion to a heel portion, and the peripheral portion is formed to be thick and thick along the soles to provide an inner arch support, an outer arch support and a heel support, and a spherical surface on the upper surface of the buttock portion. In the hard plate, a notch is formed at the center of the heel, and the reinforced wall is provided along the outer peripheral wall of the hard plate so as to face the inner arch side and the outer arch side. The inner reinforcing wall and the outer reinforcing wall are formed, and the leading edge of the inner reinforcing wall and the outer reinforcing wall is substantially perpendicular to the axis connecting the first finger ball joint portion and the center of the buttocks from the bottom of the first metatarsal to reach the fifth metatarsal. The shape was a width.
これにより、この発明の靴中敷を靴に装着して歩行、走行した場合、まず踵部において外側が着地した際、中敷本体が硬質プレートの踵補強部で拘束されているので体重負荷は踵部中央に移動される。このとき、踵部中央部、即ち踵骨の直下に最大体重負荷が負荷されるが、これは硬質プレートの切欠き部にあるクッション性発泡体で緩和されるとともに踵部の踵補強部により足の過剰な回内が阻止される。したがって、踵の着地安定性が保持される。更に、体重負荷は踏まず部へ移行さられるが中敷本体の外側アーチ側及び内側アーチ側に立設した内側アーチサポート部、外側アーチサポート部並びに硬質プレートの内側補強壁、外側補強壁により足のアーチ部が支持される。 Thus, when walking and running with the insole of the present invention attached to the shoe, when the outer side first lands on the heel part, the insole body is restrained by the heel reinforcement part of the hard plate, so the weight load is Moved to the center of the buttock. At this time, the maximum weight load is applied at the center of the buttocks, i.e., directly below the ribs, but this is alleviated by the cushioning foam in the notch of the hard plate, and the legs are supported by the buttocks of the buttocks. Is prevented. Therefore, the landing stability of the bag is maintained. In addition, the weight load is transferred to the step part, but the foot is supported by the inner arch support part erected on the outer arch side and the inner arch side of the insole body, the outer arch support part, the inner reinforcing wall of the hard plate, and the outer reinforcing wall. The arch is supported.
そして、第５指のボールジョイント部裏面に達した体重負荷は踏み付け部において硬質プレートの前縁を軸として屈曲し爪先より内向きの蹴り動作が行われ回内機能が作用し、より確実に第１指のボールジョイントへとローリングしながら誘導されて地面をしっかり踏付け、その後第１指でのピッチングが促進され、第１指〜３指での蹴りが円滑に行え、あおり（正常）歩行が促進される。そして、それと同時に本発明の中敷はその中敷本体の踵部に設けた球面状の窪みにより、歩行走行の際足が爪先方向にずれることも防止される。 The weight load that has reached the back surface of the ball joint part of the fifth finger is bent around the front edge of the hard plate at the stepping part, and the inward kicking action is performed from the toe, and the pronation function acts, so that the It is guided to the ball joint of one finger while stepping on the ground firmly, and then the pitching with the first finger is promoted, the kicking with the first to third fingers can be performed smoothly, and the gait (normal) walking Promoted. At the same time, the insole of the present invention is prevented from slipping in the toe direction during walking by the spherical depression provided in the buttocks of the insole body.
さらに、硬質プレートは、外側アーチサポート部を立方骨の位置に外側補強壁を、また内側アーチサポート部を第１楔状骨の位置に内側補強壁を対応して形成するすることで、皮下皮質の比較的厚い箇所で足の内外両側が拘束されるので足に不快感を与えることなく足の骨格を維持しフィット性を向上させることができる。 Furthermore, the rigid plate is formed by forming the outer arch support portion corresponding to the outer reinforcing wall at the position of the cubic bone and the inner arch support portion corresponding to the inner reinforcing wall corresponding to the position of the first wedge bone. Since both the inside and outside of the foot are restrained at a relatively thick portion, the foot skeleton can be maintained and the fit can be improved without causing discomfort to the foot.
また、前記靴の中敷の踏み付け部に、第１指ボールジョイント部と踵部中心とを結ぶ軸線Ｌに対してほぼ直交する屈曲溝を設け、これにより歩行走行においてスムーズな蹴り動作が得られる。In addition, a bending groove that is substantially orthogonal to the axis L that connects the first finger ball joint portion and the center of the heel portion is provided in the stepping portion of the insole of the shoe so that a smooth kicking motion can be obtained in walking and running. .
そして、前記中敷本体の第１指ボールジョイント部の裏面側に窪みを形成したので、足裏に違和感を与えることなく体重負荷が第１指部に誘導され正常歩行を行うことができる。 And since the hollow was formed in the back surface side of the 1st finger ball joint part of the said insole main body, a body weight load is induced | guided | derived to the 1st finger part and the normal walk can be performed, without giving discomfort to a sole.
さらに、上記靴の中敷は中敷本体の硬度をアスカーＣ硬度３０〜４０度とし、硬質プレートの硬度をアスカーＣ硬度８５〜９５度としたことで、クッション性が得られと共に硬質プレートにより捩れが防止される。 Furthermore, the insole of the above shoe has an insole body hardness of 30-40 degrees Asker C hardness of 30-40 degrees and a hard plate hardness of 85-95 degrees. Is prevented.
本発明の靴の中敷は、該中敷本体の踵部上面には足裏に沿った球面状の窪みを形成すると共に踵から不踏部にかけて内側アーチと外側アーチとを支持するサポート部を設け、また該硬質プレートには踵中央部に切欠き部が形成されると共に踵外周辺に踵補強壁を、また内側アーチ側と外側アーチ側とには内側補強壁、外側補強壁を立設すると共に、その前端の縁を第１楔状骨に隣接する第１中足骨の底部から第１ボールジョイント部と踵部中央とを結ぶ軸線に対してほぼ直交し第５中足骨に至る形状にしたので、踵着地での衝撃緩和及び安定性、足接地段階でのアーチ形状のサポート及び捩れの抑制、また蹴り出しの段階では硬質プレートの前縁に沿った状況で踵が地面より離れ爪先を内側向きに踏み付け部が屈曲して回内機能を作用させ、その後ローリングを最後まで支持してサポート性を向上させることができ、安定した歩行がなされる。 The insole of the shoe of the present invention includes a support portion that forms a spherical recess along the sole and supports the inner arch and the outer arch from the heel to the tread on the upper surface of the heel portion of the insole body. In addition, the hard plate has a notch in the center of the heel, a heel reinforcement wall on the outer periphery of the heel, and an inner reinforcement wall and an outer reinforcement wall on the inner and outer arch sides. In addition, the shape of the front edge of the first metatarsal bone adjacent to the first wedge bone is substantially orthogonal to the axis connecting the first ball joint portion and the center of the buttocks and reaches the fifth metatarsal bone. As a result, the heel is separated from the ground in the situation along the front edge of the hard plate at the stage of foot contact and arch-shaped support and torsion suppression at the foot contact stage, and at the kicking stage. The stepping part bends inwardly to cause the pronation function to act, Supporting the rolling to the end it is possible to improve the supportability after stable walking is performed.
