Abstract
Description
前記内装材1の一部を覆い、前記内装材1よりも伸び難い素材で形成されたループ状のラップWとを備え、前記ラップWは、
踵骨BCの内側M、背面Bおよび外側Lを連続的に覆う踵部W1と、
前記踵部W1の内側Mにおいて前記踵部W1の前端部に連なり、前記足の内側Mにおいて捩れながら足裏の下方に向かう帯状及び/又は紐状の捩れ部W2と
前記捩れ部W2の前端部に連なり、前記足裏の下方において母趾球O1まで足裏の内側部に沿って延びる内側底部W3と、
前記踵部W1の外側Lにおいて前記踵部W1の前端部に連なり、立方骨BCuの少なくとも一部及び/又は第5中足骨B5粗面B5fの少なくとも一部を覆い、更に足の甲の上面を斜め前方に向かって延び母趾の上面の一部及び前記母趾球O1の側面の少なくとも一部を覆う帯状及び/又は紐状の斜め横断部W4とを備える。
そのため、前記”棚落ち”や踵の外捩れが生じにくくなるだろう。したがって、着用者のパフォーマンスがアップするだろう。
前記第1部W41と前記第2部W42とを互いに脱着可能に連結する連結構造Jを更に備える。
前記第1部W41の前記折り返された先端部に前記シューレース3が係合している。
前記内装材1と前記外装材2との間に前記斜め横断部W4の一部が配置されている。
内装材1と外装材2との間に斜め横断部W4の一部が配置されると、ラップWの引き付け力が外装材2よりも柔軟な内装材1を通して足に直接的に作用する。したがって、”棚落ち”や踵の外捩れを抑制し易いだろう。
また、ラップWが外装材2から露出し難しく、そのため、ラップWが競技動作の妨げになるおそれもない。
前記外装材2は前記外側内装材10を覆う外側外装材20を包含し、
前記外側内装材10と外側外装材20との間に前記斜め横断部W4の一部が配置されている。
なお、本「内装材」とはタンの一部であって足の内側Mまたは外側Lに配置された材料を含む。
足の甲を包むアッパー6を締め付けるシューレース3が係合するための係合部27が前記外側外装材20の前記外側内装材10に付着されていない非付着部201に複数設けられている。
この場合、切り欠き29により、足が更に背屈しやすくなる。
前記外側内装材10に外側外装材20が少なくとも中足部の上部において非付着状態の非付着部201とを更に備え、
前記非付着部201の上部の前端から後端までの部位が前記外側内装材10に非付着状態に設定されている。
前記アウトソール4の上に配置された熱可塑性樹脂の発泡体を主体とするミッドソール5と、
前記ミッドソール5に固着され足の甲を包むアッパー6とを更に備え、
前記捩れ部W2及び斜め横断部W4が前記ミッドソール5よりも伸び難い帯状及び/又は紐状の部材で形成されている。
この場合、ラップの伸びを抑制し得る。
前記ソールに固着され足の甲を包むアッパー6とを更に備え、
前記ソールの少なくとも一部により前記内側底部W3が形成されている。
前記クリートは合成樹脂の非発泡体または金属により形成されている。
前記外装材2の下縁がソールの上縁の内面に沿って延びており、
前記外装材2の下縁およびソールの一部により前記内側底部W3の少なくとも一部が形成されている。
前記アウトソール4の上に配置された熱可塑性樹脂の発泡体を主体とするミッドソール5と、
足の少なくとも内側MのアーチMAにおいて前記ミッドソール5に付着され、足のアーチが低下するのを抑制する強化部材7とを包含し、
前記ミッドソール5を前記強化部材7が強化することで、前記内側底部W3が強化されている。
前記捩れ部W2の前端部は、前記巻上部50の上面に沿って、かつ、足裏の内側MのアーチMAと前記巻上部との間に潜り込むように延びている
図1においてラップWは踵部W1、捩れ部W2、内側底部W3および斜め横断部W4を備える。なお、図1~図9において、ラップWには小さい網点が付されている。
前記内側底部W3は前記捩れ部W2の前端部に連なり、前記足裏の下方において母趾球O1までソールの内足部に沿って延びる。
すなわち、前記足の内側Mにおいて、ラップW(前記踵部W1,前記捩れ部W2および前記内側底部W3)の上縁は踵骨BCの後端よりも上方に位置し、前記踵骨BCの後部の側面を通り、第1中足骨B1の下方に向かって延びている。換言すると、前記ラップWの上縁は前記踵骨BCの後端よりも上方の位置から前方に行くに従い下方に向かって延びている。
すなわち、前記足の外側Lにおいて、ラップW(前記踵部W1および前記斜め横断部W4)の上縁は前記踵骨BCの後端よりも上方の位置から前記踵骨BCの後部の側面を通って前方に行くに従い下方に向かって延びている。前記踵骨BCの前部の下方の位置まで延びた後、前記立方骨Bcuの下部の側面を通り、前方に行くに従い上方に向かって延びている。換言すると、前記ラップWは前記踵骨BCの後端よりも上方の位置から一旦下方へ向かって延びた後に上方へ向かって延びている。
図3に示すように、前記斜め横断部W4は足の外側Lから足の内側Mへ斜め前方へ向かって延びており、足の甲の上面において第4中足骨B4の骨底の一部を通り、かつ、第3中足骨B3の骨体および第2中足骨B2の骨頭の一部を通って第1中足骨B1の骨頭(母趾球O1)まで延びている。
図1に示すように、母趾球O1の下方に位置する前記斜め横断部W4の下端部W43(前記内側底部W3の前端部)において、前記斜め横断部W4と前記内側底部W3とが連なっている。
以下、ラップWの説明に先立って、本実施例の全体構造が説明される。図4および図5に示す本実施例はソール4Aとアッパー6とシューレース3とを備える。
図10に示すように、前記アウトソール4は接地面を有し、本実施例の場合、ゴムやウレタン樹脂などを主素材としており、ミッドソール5に比べ、ヤング率が大きく、比較的伸び難い。ゴム製等のアウトソール4の接地面41はインドア競技において、床面との間に大きな摩擦力を発生させる。
一方、前記内側内装材1Mおよび外側内装材10は、舌片状の内装材1Tの存在しない中足部ないし後足部においては、それぞれ、足の内側面および外側面に直接的に足に接する。
前記外装材2の材料としては、たとえば、人工皮革や合成皮革などの伸び難い又は実質的に伸びない材料を用いる。また、屈曲性を高めるために、外装材に適宜貫通孔を設け、同貫通孔に内装材よりも伸び難いメッシュ材を配置してもよい。
なお、図10および図11において、各部材間の接着ないし縫着部分はxxxの記号を付して図示されている。
前記外側内装材10に外側外装材20が前記踵部W1において一体に付着された付着部W10と、前記外側内装材10に外側外装材20のうちの第1の外側外装材21が少なくとも中足部の上部において非付着状態の非付着部201とを備える。
前記非付着部201の上部の前端から後端までの部位は前記外側内装材10に非付着状態に設定されている。
前記ラップWは前記内装材1の一部を覆い、前記内装材1よりも伸び難い素材で形成され、好ましくはアウトソール4およびミッドソール5よりも伸び難い素材で形成される。
なお、ヒールカウンタ23は一般に剛性が大きく、したがって、本例のようにヒールカウンタ23の外(周囲)に踵部W1が配置されている方が、ラップWがヒールカウンタ23ごと足を引き付けることができる。
より詳しくは、図10のように、前記捩れ部W2は互いに接合(接着及び/又は縫着)された内側内装材1Mと内側外装材2Mの間に挿入されて、これらの部材1M、2Mに接合されている。
図4および図5に示すように、前記踵部W1の上には踵骨の少なくとも一部を覆う外装材28が部分的に積層されて配置されている。前記外装材28の上縁は前記踵部W1および前記捩れ部W2の下部にオーバーラップしながら足の内側において前記踵部W1および前記捩れ部W2に対して並行に延びている。すなわち、前記外装材28の上縁は前方に行くに従い下方に延びており、前記外装材28の肌面側(内)に前記踵部W1および前記捩れ部W2の下部が部分的に積層されて配置されている。
図6に示すように、前記外装材28の上縁は前記踵部W1の下部にオーバーラップしながら足の外側において前記踵部W1に対して並行に延びている。すなわち、前記外装材28の上縁は前方に行くに従い下方に延びており、前記外装材28の肌面側(内)に前記踵部W1の下部が部分的に積層されて配置されている。
前記第1部W41の先端部は前記貫通孔W40に挿入されて折り返されている。
前記アッパー6を締め付けるシューレース3は、前記第1部W41の前記折り返された先端部に紐通し孔J0(図7)において係合して、ラップWの緊締力が発揮される。
すなわち、図7に示すように、靴の着用時にはシューレース3の締付により、前記第1部W41の折り返された部分を介して前記第1部W41および第2部W42(前記斜め横断部W4)が足の甲を緊締する。
なお、図4に示す第1部W41は前記クッション材1Cに断続的に縫着されてもよい。
つまり、母趾球O1からの踏み付け力が第1部W41の下端部W43に負荷されるように下端部W43がミッドソール5の上面に沿って配置されるのが好ましい。
上述のとおり、ラップWの一部(内側底部W3)は非伸縮材で形成されていなくてもよいが、アッパー6に巻きついているラップWの部分(踵部W1、捩れ部W2および斜め横断部W4)は非伸縮材で形成されている方が好ましい。
前記外側外装材20における前記斜め横断部W4を覆う部位の少なくとも一部、並びに、前記外側外装材20における前記斜め横断部W4よりも前方の部位のうちの少なくとも一部において、前記第1の外側外装材21は前記外側内装材10および第2の外側外装材22に付着されていない。
また前記シューレース3が係合するための係合部(貫通孔)27が前記第1の外側外装材21の前記外側内装材10および第2の外側外装材22に付着されていない非付着部201に複数設けられている。
また、本実施例の場合、ラップWは内側底部W3を除き、帯状に形成されているが、ラップWは複数本の互いに並列に配置された紐で形成されてもよい。
また、アッパー6に設けられるシューレース3を通す孔の径の大きさをシューレース3の径の大きさよりも小さくしてもよい。この場合、シューレース3が動きにくくなるため、連結構造の緊締状態が維持され易くなるだろう。
また、シューズは軸足のみに本発明の構造が適用されてもよいし、両足とも本発明の構造が適用されてもよい。
したがって、そのような変更および修正は本発明の範囲のものと解釈される。
