Abstract
Description
本発明は、ヒールを備えた履物に関するもので、特に走行、歩行の状態においてはヒール着地の安定かつスムーズな歩行を促すとともに、直立静止の状態では立位安定性を向上させた婦人靴に関するものである。 The present invention relates to footwear having a heel, and more particularly to a women's shoe that promotes stable and smooth walking on a heel in a running and walking state and improved standing stability in a standing still state. It is.
まず、歩行のメカニズムについて説明する。正常な成人の歩行においては、足の長手方向に沿った内外側の2つの縦アーチ、即ち踵骨から第1中足骨の頭部へかけての内側アーチと踵骨から第5中足骨の頭部へ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、即ち内側楔状骨から立方骨の先端にかけての第1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ボール部の第2アーチで体重負荷による着地衝撃圧を吸収しながら歩行するものである。また直立静止状態では、人間の体重負荷は骨格構造上主に踵骨、母趾球及び小趾球に分散され受け止められている。 First, the walking mechanism will be described. In normal adult walking, two longitudinal arches inside and outside along the longitudinal direction of the foot, that is, the medial arch from the radius to the head of the first metatarsal and the radius to the fifth metatarsal A lateral arch to the head of the foot, two lateral arches in the lateral direction of the foot, a first arch from the inner wedge bone to the tip of the cubic bone, and a head from the first metatarsal to the fifth It walks while absorbing the landing impact pressure due to the weight load at the second arch of the ball portion over the head of the metatarsal bone. In an upright stationary state, the human weight load is distributed and received mainly in the ribs, the mother heel and the small limbs in terms of the skeletal structure.
そして、歩行工程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踏まず部裏面に沿って前方へ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で足を回外して強く地面を踏付けてから第1指のボールジョイント部裏面、即ち第1中足骨と第1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付けて移動され、次に第1基節骨と第1末節骨を反らせてピッチングさせながら第1末節骨(第1指)裏面で地面を把持して第1〜第5指、特に第1、2、3指で地面を蹴って前進する工程を繰り返しながら歩行するものと言われている。 In the walking process, the weight load is first applied to the back surface of the buttocks while rotating from the outside of the buttocks to the inside, and then forward from the back of the buttocks along the back of the buttocks in the longitudinal direction of the foot. The ball joint of the first finger is moved while being unrolled, and the foot of the fifth finger is turned back, that is, the back of the joint of the fifth metatarsal bone and the fifth proximal phalanx, and the foot is stepped strongly on the ground. While moving to the back of the joint, that is, to the joint back of the first metatarsal bone and the first proximal phalanx, stepping on the ground and moving, and then bending the first proximal phalanx and the first distal phalanx while pitching It is said to walk while repeating the process of grasping the ground with the back surface of the first distal phalanx (first finger) and kicking the ground with the first to fifth fingers, especially the first, second and third fingers. .
一般に婦人靴に用いられるヒールは、踵部に対して後寄せにつけられたセット・バック・ヒールタイプからヒール前後を大きくくった古典的なルイ・ヒールタイプまで各種用いられるが、いずれも右足、左足用の差別なく兼用されているものが使用されており、生産性やファッション性を優先したものが多い。これら従来の履物は、上記歩行のメカニズムを考慮されずに設けられているため、踵着地が不安定で歩行には不向きで健康上望ましくなかった。またこれらの婦人靴のヒールは踵部の中心線に合わせ第3指に指向して配されていることから、体重負荷重心がそれに沿って自然と誘導され外股歩行がなされる傾向にあった。 In general, heels used for women's shoes are used in a variety of ways, from the set back heel type attached to the back of the hips to the classic Louis heel type with a large heel front and back. Those that are used without discrimination are used, and many of them give priority to productivity and fashionability. Since these conventional footwear are provided without considering the above walking mechanism, the landing is unstable and unsuitable for walking, which is not desirable for health. Also, since the heels of these women's shoes are oriented toward the third finger in line with the center line of the buttocks, there was a tendency for the weight-bearing center of gravity to be guided naturally along that and to walk on the outer crotch .
また、ヒールを備えた靴に関して、従来長時間履いていても疲労が少ない体重支持の安定性に優れる目的として、特開平7−155204号公報により足の爪先部分から土踏まず部分に向かって延びる靴底接地部の後端を、足の踝部から鉛直方向に下ろした垂線よりも1cm乃至4cmだけ踵部寄りに位置させ、上記靴底接地部の後端からヒール部分の後端に向かって延びる靴底後部の下面の傾斜角を、靴の内底に形成された傾斜部の平均傾斜角度と同等もしくはそれ以下に設定した靴が提案されている。 In addition, regarding a shoe having a heel, as an object of excellent stability of weight support with little fatigue even when worn for a long time, a shoe sole that extends from the toe portion of the foot toward the arch portion according to Japanese Patent Laid-Open No. 7-155204 The rear end of the grounding part is positioned 1 cm to 4 cm closer to the hip part than the vertical line extending vertically from the heel part of the foot, and the shoe extends from the rear end of the shoe sole grounding part toward the rear end of the heel part. There has been proposed a shoe in which the inclination angle of the lower surface of the bottom rear portion is set to be equal to or less than the average inclination angle of the inclined portion formed on the inner bottom of the shoe.
しかしながら、このハイヒール靴は、ヒールの踵底接地部の位置が踵骨の最下点から鉛直に下ろした位置より前方に設定されることになり、このため歩行において足裏に突き上げなどの違和感が生じ、スムーズな歩行が得られない問題点が生じる。また静止状態では、踵部における体重負荷重心が踵接地後端より踵寄りに掛かることから、爪先が浮上して背面へ転倒するなど問題がある。 However, in this high heel shoe, the position of the ground contact part of the heel of the heel is set to the front from the position vertically lowered from the lowest point of the rib, and therefore, there is a sense of incongruity such as pushing up to the sole of the foot during walking. This causes a problem that smooth walking cannot be obtained. In the stationary state, the weight-bearing center of gravity of the heel part is applied closer to the heel than the rear end of the heel contact, so that there is a problem that the toe lifts and falls to the back.
その他の従来の婦人靴に関して、特開2002−85110号公報によりヒール後部の接地面が斜めにカットされており、該ヒールカット面の前縁線が靴底中心線の垂線に対して2〜10度外側方向へ傾斜している靴底であって、通勤や仕事の一場面としてヒール付き婦人靴を履いた女性が走らなければならない状況が発生しても、その場面でも不自然な力が足にかかることなく、足、筋肉の緊張を少なくし早足の走行ができるということが開示されている。しかしながら、この靴底もカット面の前縁線が靴底中心線の垂線に対して外側に傾斜する靴底であるから、爪先が開いた歩行、即ちO脚の歩行を促す傾向にあった。
解決しようとする問題点は、ヒールを備えた履物において、歩行、走行の状態ではヒール着地時の安定かつスムーズな歩行がなされず、また直立静止の状態では立位安定が図られていない点である。また従来の履物は、歩行者が無意識に誘導せられて外股歩行となり、正常歩行がなされない点である。 The problem to be solved is that, in footwear with heels, stable and smooth walking at the heel landing is not performed in walking and running states, and standing stability is not achieved in a standing still state. is there. In addition, the conventional footwear is that the pedestrian is unconsciously guided to the outer crotch walking, and normal walking is not performed.
本発明は、ヒールを備えた履物において、ヒールの踵接地の後端を、足の踵の踵骨最下点から鉛直に下ろした垂線とヒール接地面との交点に位置させ、かつ該交点と第2指先端とを結ぶ足裏縦軸線にヒールの長手中心線を一致させてヒールを設けたことを特徴とする。 According to the present invention, in a footwear having a heel, the rear end of the heel contact with the heel is positioned at the intersection of a perpendicular line vertically from the lowest point of the rib of the foot heel and the heel contact surface, and the intersection A heel is provided such that the longitudinal center line of the heel coincides with the longitudinal axis of the sole connecting the tip of the second finger.
本発明の履物は、ヒールの接地部の後縁部を踵骨の最下点から鉛直に下ろした垂線とヒール接地面との交点に位置させ、該交点と第2指先端とを結ぶ足裏縦軸線にヒールの長手中心線を一致させてヒールを設けたことによって、歩行中での踵着地の状態では膝が伸びた状態で着地できるとともに靴底と地面とのなす角度が減少し、また直接踵骨の最下点に掛かる体重負荷を受け止めることができるので、着地安定性を向上させるとともにスムーズな歩行がなされるという利点がある。 The footwear of the present invention is such that the rear edge of the ground contact portion of the heel is positioned at the intersection of a perpendicular line vertically lowered from the lowest point of the rib and the ground contact surface of the heel, and the sole connecting the intersection and the tip of the second finger By providing the heel so that the longitudinal center line of the heel coincides with the vertical axis, the knee can be extended with the knee stretched while walking while the angle between the sole and the ground is reduced. Since the weight load directly applied to the lowest point of the rib can be received, there is an advantage that the landing stability is improved and smooth walking is performed.
また静止状態においても、踵骨の最下点から鉛直に下ろした垂線上にヒールの接地後縁部が一致するため、踵部に掛かる体重負荷をヒールの接地後縁部で確実に支持され、爪先が浮上することがなく安定性が図られるという利点がある。さらに、本発明の婦人靴は、体重負荷の重心がヒール着地点から第2指方向に沿って誘導せられて、足を真直ぐ踏み出すことができ無意識に外股歩行が防止され、正常歩行がなされる。 Even in a stationary state, since the ground contact rear edge of the heel coincides with a perpendicular line vertically lowered from the lowest point of the rib, the weight load applied to the hip is reliably supported by the ground contact rear edge of the heel, There is an advantage that the toe does not float and stability is achieved. Furthermore, the women's shoes of the present invention are guided in the direction of the second finger from the heel wearing point so that the center of gravity of the weight load can be stepped straight, and the outer leg walking is prevented unintentionally and normal walking is performed. The
本発明は、歩行及び静止状態で安定性の向上及び正常歩行させる目的を、ヒール高さに関係なくヒールの装着位置を設定するだけで、簡単に実現した。 In the present invention, the purpose of improving stability and normal walking while walking and standing is simply realized by simply setting the heel mounting position regardless of the heel height.
図1は、本発明の実施の形態1による履物を示した側面図である。図2は図1に示した履物の底面図である。また、1は履物、2は胛被、3は靴底、4は靴底本体、5はヒール、6はヒール本体、7は底部、8はヒール接地面、9は後縁、10は踵骨の最下点、11は垂線、12は交点、13は足裏縦軸線、14は従来の踵中心線、15はヒールの長手中心線、Lは足長、L1は踵後端からヒールの後縁までの距離である。 FIG. 1 is a side view showing a footwear according to Embodiment 1 of the present invention. 2 is a bottom view of the footwear shown in FIG. Also, 1 is footwear, 2 is a cover, 3 is a shoe sole, 4 is a sole body, 5 is a heel, 6 is a heel body, 7 is a bottom, 8 is a heel grounding surface, 9 is a trailing edge, and 10 is a rib , 11 is a perpendicular line, 12 is an intersection, 13 is a sole longitudinal axis, 14 is a conventional heel center line, 15 is a heel longitudinal center line, L is a foot length, and L1 is from the back end of the heel to the back of the heel The distance to the edge.
本発明の履物1は、図1に示すように胛被2と靴底3とから構成され、靴底3は靴底本体4とヒール5とから構成される。またヒール5は広い上面と狭い下面とその両面を連結する傾斜面で形成された形状からなり、ヒール本体6と底部7と構成される。ヒール本体6は硬質材料が用いられ、合成ゴムまたは革積み、合成樹脂、木、軽合金またはそれらを組み合わせたものが使用される。底部7は足に掛かる衝撃を吸収するためにヒール本体より硬度が低い材料が用いられる。 As shown in FIG. 1, the footwear 1 of the present invention includes a heel cover 2 and a shoe sole 3, and the shoe sole 3 includes a shoe sole body 4 and a heel 5. Further, the heel 5 has a shape formed by a wide upper surface, a narrow lower surface, and an inclined surface connecting both surfaces thereof, and is constituted by a heel body 6 and a bottom portion 7. The heel body 6 is made of a hard material, and synthetic rubber or leather, synthetic resin, wood, light alloy, or a combination thereof is used. The bottom portion 7 is made of a material having a hardness lower than that of the heel body in order to absorb an impact applied to the foot.
ヒール5はその踵接地部の後縁9を足の踵骨最下点10から鉛直に下ろした垂線11とヒール接地面8との交点12に合わせて配置する。この場合、足の踵骨最下点10は、調査の結果足裏からみて踵後端から足長(L)の11%〜15%の位置にあることが判った。よって、ヒール5は図2に示すようにその後縁9を足長(L)に対して13%の位置、即ち踵までの長さ(L1)に設定することで交点12に配置することができる。例えば、足長23cmの場合、足の踵後端(履物踵内面)より23cm×0.13=2.99≒3cmの位置に設定する。 The heel 5 is arranged so that the rear edge 9 of the heel contact portion thereof is aligned with the intersection 12 of the vertical line 11 and the heel contact surface 8 that are vertically lowered from the lowest rib 10 of the foot. In this case, the lowest point 10 of the ribs of the foot was found to be at a position of 11% to 15% of the foot length (L) from the rear end of the foot as a result of the investigation. Accordingly, as shown in FIG. 2, the heel 5 can be disposed at the intersection 12 by setting the rear edge 9 to a position of 13% of the foot length (L), that is, the length to the heel (L1). . For example, when the foot length is 23 cm, the position is set to 23 cm × 0.13 = 2.99≈3 cm from the rear end of the foot (inner surface of the footwear).
そして、ヒール5は該交点12と第2指先端とを結ぶ足裏縦軸線13にヒールの長手中心線15を一致させて靴底本体4に装着する。この足裏縦軸線13は従来の踵中心線14より約7〜14度(θ)内側に傾斜した位置に相当する。 The heel 5 is attached to the sole body 4 with the longitudinal center line 15 of the heel aligned with the sole longitudinal axis 13 connecting the intersection 12 and the tip of the second finger. The sole vertical axis 13 corresponds to a position inclined about 7 to 14 degrees (θ) inward from the conventional heel center line 14.
ヒール5は、実施例ではヒール高さ55mmのハイヒールを使用したが、ミドルヒール、ローヒールでも上記通りに配設すれば同じ作用効果が得られるので、通常用いられるヒール高であれば使用可能である。また本発明のヒール5は靴底本体4を別に準備し接着成形したが、別の実施例として靴底本体4と天然ゴム、合成ゴム、熱可塑性樹脂などの成形材料で一体に成形しても良い。本発明の履物に使用するヒールの種類はフレンチヒール、コンチネンタルヒール、ウェッジヒールなどが用いられ特段側面の形状は問わない。 As the heel 5, a high heel having a heel height of 55 mm is used in the embodiment. However, even if the middle heel and the low heel are arranged as described above, the same operation and effect can be obtained. . Further, the heel 5 of the present invention is prepared by separately preparing the sole body 4 and bonded and molded. However, as another embodiment, the sole 5 may be integrally molded with a molding material such as natural rubber, synthetic rubber or thermoplastic resin. good. The type of heel used in the footwear of the present invention is French heel, Continental heel, wedge heel or the like, and the shape of the special side is not limited.
本発明の婦人靴は、上記ヒール構造からヒールの接地後縁9が体重負荷(W)の掛かる踵骨の最下点10の垂線11上で着地する歩行動作となり、これによって膝が伸びた状態での歩行がなされるため、踵接地時の靴底と地面とのなす角度が減少し、足へ無理な負担が掛からず、着地時の安定性向上及びスムーズな正常歩行が可能となった。また、本発明の履物は直立静止状態においても踵部に掛かる体重負荷がヒール接地後縁9で確実に支持されるので.立位安定性を向上させることができた。本発明の婦人靴を着用して官能試験を行った結果、5名中5名が歩行及び静止状態での安定性が良好との評価を得た。 The women's shoes of the present invention have a walking action in which the ground contact trailing edge 9 of the heel lands on the perpendicular line 11 at the lowest point 10 of the rib on which the weight load (W) is applied from the above heel structure, whereby the knee is extended. Since walking on the ground is performed, the angle between the sole and the ground when the heel is touched is reduced, so that an excessive load is not applied to the foot, and stability at the time of landing is improved and smooth normal walking is possible. Further, the footwear of the present invention can improve the standing stability because the weight load applied to the buttocks is surely supported by the heel contact trailing edge 9 even when standing upright. As a result of performing a sensory test while wearing the women's shoes of the present invention, 5 out of 5 obtained an evaluation that the stability in walking and stationary was good.
本発明は婦人靴を実施例としてあげたが、紳士靴やウォーキングシューズなどの用途にも適用できる。 In the present invention, women's shoes are given as examples, but the present invention can also be applied to uses such as men's shoes and walking shoes.
