- the toe accommodating portion 117 has a cut portion 115 that is a cut corresponding to the finger crotch 133 between the thumb finger 131 and the index finger 132. If the stretchable part 110 is excessively arranged on the thumb 131 side of the notch part 115, the contraction force is biased toward the inner side part 137 of the foot, and there is a concern that the wearer may feel uncomfortable. Therefore, in the embodiment, the end portion 102b on the thumb 131 side of the first strip portion 102 is disposed so as to straddle the extended line Lc extending along the cutting edge of the cutting portion 115. By arranging in this way, it is possible to alleviate the bias of the contraction force.
- the end portion 108b of the third band-shaped portion 108 on the thumb 131 side is disposed so as to straddle the extended line Lc extending along the cut edge of the cut portion 115.

Abstract
Description
しかし、従来の草鞋は、足に装着するために多大な手間がかかり、また不慣れな場合には足に絞めた紐がその当接部位を傷付けるおそれもある。これらのことは草鞋の特性を履物として実用化することの障害となっていた。
このことから、発明者は草鞋の持つ特性を例えば靴下などの足にまとう履物に再現することが課題であると認識した
実施の形態は、このような認識に基づいて案出されたもので、以下にその具体的な構成を説明する。
以下、本発明を好適な実施の形態をもとに各図面を参照しながら説明する。実施の形態、変形例では、同一または同等の構成要素、部材には、同一の符号を付するものとし、適宜重複した説明は省略する。また、各図面における部材の寸法は、理解を容易にするために適宜拡大、縮小して示される。また、各図面において実施の形態を説明する上で重要ではない部材の一部は省略して表示する。
また、第1、第2などの序数を含む用語は多様な構成要素を説明するために用いられるが、この用語は一つの構成要素を他の構成要素から区別する目的でのみ用いられ、この用語によって構成要素が限定されるものではない。
装着具100は爪先側で足の指を収容するための爪先収容部117を備える。図1、図2に示すように、爪先収容部117は拇指袋112と指袋116とを含む。拇指袋112は、拇指131の少なくとも一部を収容する袋状の部分である。拇指袋112は拇指131を他の指から独立して収容する袋部である。指袋116は人差指132から小指134までの4本の指を収容する袋部である。爪先収容部117は、例えば糸を袋状に編成することによって形成されてもよい。
伸縮部110は、人の足に装着されることで、足形状に沿って伸び、その復元力によって縮む方向の収縮力を足に付与する帯状体である帯状部を複数含む。具体的には、伸縮部110は、人の足に装着したときにそれぞれ所定部位に当接する程度の伸縮性を有する、第1帯状部102と、第2帯状部104と、接続帯状部106と、第3帯状部108と、を含む。装着具100は、伸縮部110が拇指屈筋群に荷重を加えることで、伸筋に弛緩をもたらし、ふくらはぎのむくみや足の疲労を緩和することができる。伸縮部110は胴部120より大きな伸縮性を有する材料から形成される。特に、伸縮部110は胴部120より弾性限界が大きく弾性率が小さいシート状の生地から形成される。伸縮部110は、例えばゴムなど大きな弾性を有する素材が織り込まれた織物から形成されてもよい。伸縮部110は胴部120より厚い生地から形成されてもよい。
図1~図5に示すように、第1帯状部102は、足裏128側の拇指131の付け根から足の内側部137を越えて足甲129側のくるぶし127の近傍に至る部位に当接するように形成される。第1帯状部102は、足裏128側の拇指131の付け根から内側部137を越えてくるぶし127の近傍に至る部位に収縮力を付与することができる。特に、第1帯状部102の爪先側の端部は人差指132の付け根から拇指131の付け根にかけて形成される。一例として、第1帯状部102の幅は18mmから28mmであり、好ましくは20mm以上で26mm以下の範囲に形成されてもよい。なお、この明細書においてくるぶし127の近傍とは、くるぶし127の範囲およびくるぶし127の裾から周囲30mm以内の範囲をいう。
第2帯状部104は、足甲129側の拇指131の付け根から内側部137を越えて足裏128側を通り外側部138を越えてくるぶし127の近傍に至る部位に当接するように形成される。特に、第2帯状部104の爪先側の端部は人差指132の付け根から拇指131の付け根にかけて形成される。第2帯状部104を含むことで、足甲129側の拇指131の付け根から内側部137を越えて足裏128側を通り外側部138を越えてくるぶし127の近傍に至る部位に収縮力を付与することができる。一例として、第2帯状部104の幅は11mmから19mmであり、好ましくは13mm以上で17mm以下の範囲に形成されてもよい。第2帯状部104の幅は第1帯状部102の幅より小さく形成されてもよい。
主に図3~図5を参照して接続帯状部106を説明する。実施の形態において、接続帯状部106は、第1帯状部102の延長線上の近傍から足の後側を越えて第2帯状部104の延長線上の近傍に至る部位に当接するように形成される。特に、接続帯状部106は第1帯状部102と第2帯状部104とに直接的または間接的に繋げられる。接続帯状部106を含むことで、足の後側の部位を含めて接続帯状部106が当接する部位に収縮力を付与することができる。また、第1帯状部102および第2帯状部104と一体に繋がることで、これらの帯状部が当接する部位に連続して収縮力を付与することができる。接続帯状部106は、例えばくるぶし127の近傍の領域で踵135の上側を外側部138から内側部137にわたる部位に当接する。一例として、接続帯状部106の幅は11mmから19mmであり、好ましくは13mm以上で17mm以下の範囲に形成されてもよい。接続帯状部106の幅は第1帯状部102の幅より小さく形成されてもよい。
収縮力が足の内側部137側に過度に偏ると装着者に違和感を与える懸念がある。そこで、実施の形態では、伸縮部110は足の外側部138側に寄った領域に当接する第3帯状部108を含む。図1、図4に示すように、第3帯状部108は、足甲129側の拇指131の付け根から外側部138を越えてくるぶし127の近傍に至る部位に当接して、第2帯状部104及び接続帯状部106に繋げられるように形成される。実施の形態では、特に、第3帯状部108の爪先側の端部は人差指132の付け根から拇指131の付け根にかけて形成される。一例として、第3帯状部108の幅は18mmから28mmであり、好ましくは20mm以上で26mm以下の範囲に形成されてもよい。第3帯状部108の幅は第1帯状部102の幅と略等しく形成されてもよい。
(1)例えば編成によって、伸縮部110の第1帯状部102と、第2帯状部104と、接続帯状部106と、第3帯状部108とを一体に形成する(S141)。
(2)例えば編成によって、別に形成された伸縮部110と一体に胴部120を形成する(S142)。この際、足首部122は胴部120と一体に形成してもよい。
(3)例えば編成によって、拇指袋112と指袋116とを含む爪先収容部117を形成する(S143)。
(4)例えば編成によって、踵収容部114を形成する(S144)。
(5)例えば縫合によって、胴部120の前側の開口120bに爪先収容部117を結合する(S145)。
(6)例えば縫合によって、胴部120の踵孔120cに踵収容部114を結合する(S146)。
さらに検査や梱包などの工程を経て装着具100が製造される。なお、製造工程140は、必要に応じて工程の順序を入れ替えてもよく、一部の工程を削除し、複数の工程を併合し、複数の工程に分割しあるいは別工程を追加してもよい。
(1)拇指袋112を拇指131に被せ、伸縮部110の前側の端部110bを拇指131および人差指132側にセットする。
(2)踵収容部114を踵135に被せ、伸縮部110の後側の端部110cをくるぶし127側にセットする。
(3)第1帯状部102を、足裏128側の拇指131の付け根から足の内側部137を越えて足甲129側のくるぶし127の近傍に至る部位に当接するように位置合わせする。
(4)第2帯状部104を、足甲129側の拇指131の付け根から内側部137を越えて足裏128側を通り外側部138を越えてくるぶし127の近傍に至る部位に当接するように位置合わせする。
(5)接続帯状部106を、第1帯状部102の延長線上の近傍から足の後側を越えて第2帯状部104の延長線上の近傍に至る部位に当接するように位置合わせする。
(6)第3帯状部108を、足甲129側の拇指131の付け根から外側部138を越えてくるぶし127の近傍に至る部位に当接するように位置合わせする。
実施の形態の装着具100を、このように使用することで、拇指屈筋群を圧縮して伸筋群の弛緩をもたらし、ふくらはぎのむくみや足の疲労を緩和することができる。
実施の形態の装着具100は、人の足に装着したときにそれぞれ所定部位に当接する程度の伸縮性を有する、第1帯状部102と、第2帯状部104と、接続帯状部106と、を備え、第1帯状部102は、足裏128側の拇指131の付け根から足の内側部137を越えてくるぶし127の近傍に至る部位に当接するように形成され、第2帯状部104は、足甲129側の拇指131の付け根から足の内側部137を越えて足裏128側を通り足の外側部138を越えてくるぶし127の近傍に至る部位に当接するように形成され、接続帯状部106は、第1帯状部102の延長線上の近傍から足の後側を越えて第2帯状部104の延長線上の近傍に至る部位に当接するように形成される。この構成によれば、容易に装着できる装着具に、歩行に適した草鞋に類似する特性を再現することができる。特に拇指131の付け根からくるぶし127の近傍及び足の後側にかけて収縮力を付与できる。この結果、拇指屈筋群を圧縮することで伸筋群の弛緩をもたらし、ふくらはぎのむくみや足の疲労を緩和することができる。
以下、変形例について説明する。変形例の説明では、実施の形態と同一または同等の構成要素、部材には、同一の符号を付する。実施の形態と重複する説明を適宜省略し、実施の形態と相違する構成について重点的に説明する。
