Description

本発明は、紳士靴や運動靴等の各種靴の本底（靴底）とその靴底を備えた靴に関し、特に、屈曲性に優れ、歩行し易い靴底とその靴底を備えた靴に関する。   The present invention relates to a sole having various soles such as men's shoes and athletic shoes, and a shoe having the sole, and in particular, a shoe having excellent flexibility and a walking ability and a shoe having the sole. About.

紳士靴や婦人靴、運動靴といった各種靴が抱える課題の一つとして歩き易さの改善がある。効率良く、疲れにくい歩き方としてあおり歩行が知られている。あおり歩行とは歩行時や走行時の足の動きのことをいい、図９（ａ）（ｂ）に示すように、踵−小趾球−踏み付け部（拇趾球〜小趾球のあたり）−足趾の順に着地する一連の動きのことをいう。したがって、あおり歩行し易い靴が歩き易い靴に繋がる。そのためには、靴底が足の動きにつれて着地し易く（靴底が屈曲し易く）、引き上げ易い（屈曲した靴底が返り易い：戻り易い）ことが望まれる。従来、屈曲性を向上させるため、底面に一又は二以上の横溝が形成された靴底（特許文献１〜３）が提案されている。   One of the challenges faced by various shoes such as men's shoes, women's shoes, and athletic shoes is to improve walking. A walk is known as an efficient and fatigue-free way of walking. Ascending walking refers to the movement of the foot during walking or running, and as shown in FIGS. 9A and 9B, the heel-small ball-stepping portion (around Ryukyu-Ryukyu) -A series of movements that land in the order of the toes. Therefore, shoes that are easy to walk are connected to shoes that are easy to walk. For this purpose, it is desirable that the shoe sole is easy to land as the foot moves (the shoe sole is easily bent) and lifted (the bent shoe sole is easy to return: easy to return). Conventionally, in order to improve flexibility, shoe soles (Patent Documents 1 to 3) in which one or more lateral grooves are formed on the bottom surface have been proposed.

（靴底の実施形態１）
本発明の靴底１の実施形態の一例を図１（ａ）〜（ｃ）及び図２を参照して説明する。本発明の靴底１は他の部分の肉厚よりも肉薄な屈曲薄肉部１０を備え、屈曲薄肉部１０の靴幅内側９を靴幅外側８よりも薄くして、屈曲部６が「あおり歩行」時の足裏の動きに追随して屈曲し易くなるようにしたものである。本実施形態及び以下の実施形態における屈曲部６は前記課題を解決するための手段において定義したとおりである。 (Embodiment 1 of shoe sole)
An example of an embodiment of a shoe sole 1 of the present invention will be described with reference to FIGS. 1 (a) to 1 (c) and FIG. The shoe sole 1 of the present invention includes a bent thin portion 10 that is thinner than the thickness of the other portions. The bent inner portion 9 of the bent thin portion 10 is thinner than the outer width 8 of the shoe, and the bent portion 6 is “an It is easy to bend following the movement of the sole at the time of “walking”. The bent part 6 in this embodiment and the following embodiments is as defined in the means for solving the above-mentioned problems.

図１の靴底１は靴着用時に足の足趾部分が当たる足趾接触部２と、足の踏み付け部（前足部：親指の付け根付近）が当たる踏み付け部３と、足の土踏まず部分に相当する土踏まず部（中足部）４と、足の踵部分が当たる踵部（後足部）５を備える（この構造は以下の全ての実施形態の靴底において同じ）。本発明の靴底１は紳士靴や運動靴といった各種靴の本底として図２に示すように使用可能なものである（この使用形態も以下の全ての実施形態において同じ）。   The shoe sole 1 in FIG. 1 corresponds to a toe contact portion 2 where the toe portion of the foot hits when wearing shoes, a stepping portion 3 where the foot stepping portion (the front foot portion: near the base of the thumb) hits, and an arch portion of the foot The arch portion (middle foot portion) 4 and the heel portion (rear foot portion) 5 to which the heel portion of the foot hits (this structure is the same in the soles of all the embodiments below). The shoe sole 1 of the present invention can be used as a sole of various shoes such as men's shoes and athletic shoes as shown in FIG. 2 (this usage pattern is the same in all the following embodiments).

この実施形態では、靴底１の横幅方向に溝７を形成して靴底１の他の部分よりも一段窪ませ、その溝部分の靴底肉厚を靴底の他の部分よりも肉薄にすることにより屈曲肉薄部１０を形成し、この屈曲肉薄部１０と溝７で屈曲部６を形成してある。溝７は靴幅方向に横長であり、靴底の前後方向に一定（略一定を含む：以下同じ）間隔で多数本設けられている。溝７は図１（ｂ）（ｃ）に示すように、靴幅外側８から靴幅内側９に向けて次第に深くして、屈曲肉薄部１０の靴幅外側８の肉厚Ｌ1（図１（ｂ））よりも靴幅内側９の肉厚Ｌ２（図１（ａ））の方が次第に薄くなるようにしてある。このような肉厚構造とすることにより、歩行時に靴幅内側９が靴幅外側８に比べて屈曲し易くなり、返りも良くなるため、あおり歩行し易くなって（踏みこみ易く、返り易くなって）、歩行や走行がスムーズにできるようにしてある。   In this embodiment, a groove 7 is formed in the lateral width direction of the shoe sole 1 so as to be recessed by one step from the other part of the shoe sole 1, and the thickness of the shoe sole of the groove part is made thinner than the other part of the shoe sole. In this way, the bent thin portion 10 is formed, and the bent portion 6 is formed by the bent thin portion 10 and the groove 7. The grooves 7 are horizontally long in the shoe width direction, and a plurality of grooves 7 are provided at regular intervals (including substantially constant: the same applies hereinafter) in the longitudinal direction of the shoe sole. As shown in FIGS. 1B and 1C, the groove 7 is gradually deepened from the shoe width outer side 8 toward the shoe width inner side 9, and the thickness L1 (FIG. The wall thickness L2 (FIG. 1 (a)) on the inner side 9 of the shoe width is gradually made thinner than b)). Such a thick structure makes it easier to bend the shoe width inner side 9 than the shoe width outer side 8 during walking, and to improve the return, making it easier to walk sideways (easy to step on and return). To walk and run smoothly.

図１（ａ）の溝７は靴底１の靴幅外側８から靴幅内側９まで一連に横断する均一幅の直線状の連続溝であるが、溝７はあおり歩行し易くなれば、その形状、本数、深さ、間隔、横幅、長さ、形成領域、形成位置等は任意に設定することができる。例えば、形状は波型状や弧状等であってもよく、溝幅は靴底の靴幅外側８から靴幅内側９に向けて次第に幅広くすることもできる。また、溝７の形状は横長溝に限らず、他の形状、例えば、ダイヤ形の溝や亀甲形の溝などが横長溝となるように一列に配列させたものであってもよい。   The groove 7 in FIG. 1 (a) is a straight continuous groove having a uniform width that continuously traverses from the shoe width outer side 8 to the shoe width inner side 9 of the shoe sole 1. If the groove 7 is easy to walk, The shape, number, depth, interval, lateral width, length, formation region, formation position, and the like can be arbitrarily set. For example, the shape may be a wave shape, an arc shape, or the like, and the groove width may be gradually increased from the shoe width outer side 8 to the shoe width inner side 9 of the shoe sole. The shape of the groove 7 is not limited to the horizontally long groove, but may be another shape, for example, a diamond-shaped groove or a turtle shell-shaped groove arranged in a row so as to be a horizontally long groove.

図１（ａ）の溝７は靴底１の裏面略全面（全域）に形成されているが、溝７は靴底１の踏み付け部３付近にだけ設けたり、歩行時に屈曲し易くなる部分、例えば、足のＭＰ関節（足趾の付け根付近）が当たる部分（ＭＰ関節接触部）の付近や、拇趾球が当たる部分（拇趾球接触部）の付近にだけ設けたりすることもできる。溝７は靴幅外側８から靴幅内側９まで断続的に設けた断続溝とすることもできる。溝７は靴幅外側８からＭＰ関節接触部、拇趾球接触部に向けて、次第に連続的に又は段階的に深くして、屈曲肉薄部１０が次第に薄くなるようにすることもできる。   The groove 7 in FIG. 1 (a) is formed on substantially the entire back surface (entire area) of the shoe sole 1, but the groove 7 is provided only in the vicinity of the stepping portion 3 of the shoe sole 1 or a portion that is easily bent during walking, For example, it can be provided only in the vicinity of the portion where the MP joint of the foot (near the base of the toe) hits (MP joint contact portion) or in the vicinity of the portion where the Ryukyu hits (Ryukyu contact portion). The groove 7 may be an intermittent groove provided intermittently from the shoe width outer side 8 to the shoe width inner side 9. The groove 7 can be gradually and gradually deepened from the shoe width outer side 8 toward the MP joint contact portion and the Ryukyu contact portion so that the bent thin portion 10 becomes gradually thinner.

（靴底の実施形態２）
本発明の靴底１の実施形態の他例を図３（ａ）〜（ｃ）を参照して説明する。この実施形態の靴底１の基本的構造は実施形態１の靴底１と同様である。実施形態１の靴底１と異なるのは、靴底１の裏面に形成された溝７の形状、形成位置、本数、長さである。この内側７は靴底１の踏み付け部３から土踏まず部４までの間に、間隔をあけて四本設けてあり、靴幅内側９から靴幅外側８までの全長を横断することなく、靴幅内側面９ａにのみ開口するように形成してある。 (Embodiment 2 of shoe sole)
Another example of the embodiment of the shoe sole 1 of the present invention will be described with reference to FIGS. The basic structure of the shoe sole 1 of this embodiment is the same as that of the shoe sole 1 of the first embodiment. What differs from the shoe sole 1 of the first embodiment is the shape, forming position, number, and length of the groove 7 formed on the back surface of the shoe sole 1. The inner side 7 is provided with four spaces between the stepping part 3 and the arch part 4 of the shoe sole 1 with a space between them, without crossing the entire length from the shoe width inner side 9 to the shoe width outer side 8. It is formed so as to open only on the inner side surface 9a.

図３（ａ）〜（ｃ）の溝７は靴幅外側８から靴幅内側９に向けて次第に幅広くし、更に、溝７を靴幅外側８から靴幅内側９に向けて次第に深くして、屈曲肉薄部１０の靴幅外側８の肉厚Ｌ１よりも靴幅内側９の肉厚Ｌ２の方が次第に薄くなるようにしてある。このような肉厚構造とすることにより、歩行時に、靴の靴幅内側９が靴幅外側８に比べて屈曲し易くなり、返りも良くなるため、あおり歩行し易くなって、歩行や走行がスムーズにできるようにしてある。溝７は靴底１の横幅方向に均一幅とすることもできる。溝７の形状は直線状や弧状、波形状といった形状であってもよく、本数や間隔も任意に設定することができる。この溝７は靴幅外側８から靴幅内側９まで断続的に設けた断続溝とすることもできる。溝７は靴幅外側８からＭＰ関節接触部、拇趾球接触部に向けて、次第に連続的に又は段階的に深くして、屈曲肉薄部１０が次第に薄くなるようにすることもできる。   3 (a) to 3 (c), the groove 7 is gradually widened from the shoe width outer side 8 toward the shoe width inner side 9, and the groove 7 is gradually deepened from the shoe width outer side 8 toward the shoe width inner side 9. The thickness L2 of the shoe width inner side 9 is gradually thinner than the thickness L1 of the shoe width outer side 8 of the bent thin portion 10. By having such a thick structure, when walking, the shoe width inner side 9 of the shoe becomes easier to bend than the shoe width outer side 8, and the return is also improved. It can be done smoothly. The groove 7 can also have a uniform width in the lateral width direction of the shoe sole 1. The shape of the groove 7 may be a linear shape, an arc shape, or a wave shape, and the number and interval can be arbitrarily set. The groove 7 may be an intermittent groove provided intermittently from the shoe width outer side 8 to the shoe width inner side 9. The groove 7 can be gradually and gradually deepened from the shoe width outer side 8 toward the MP joint contact portion and the Ryukyu contact portion so that the bent thin portion 10 becomes gradually thinner.

本発明の靴底１の実施形態の他例を、図４（ａ）〜（ｄ）を参照して説明する。この実施形態の靴底１の基本的構造も、実施形態１の靴底１と同様である。 (Embodiment 3 of the shoe sole)
Another example of the embodiment of the shoe sole 1 of the present invention will be described with reference to FIGS. The basic structure of the shoe sole 1 of this embodiment is the same as that of the shoe sole 1 of the first embodiment.

図４（ａ）〜（ｃ）の靴底１は、実施形態１及び２の溝７の代わりに、靴幅方向に貫通する穴（横穴）１１を開口して屈曲肉薄部１０を形成してある。横穴１１は靴幅外側８から靴幅内側９に向けて次第に幅広く形成されている。横穴１１の深さを、靴幅内側９よりも靴幅外側８を深くして、靴底1の屈曲肉薄部１０の肉厚（穴の上下の合計肉厚Ｌ３＋Ｌ４：図４（ｄ））が靴幅外側８よりも靴幅内側９が薄くなるようにしてある。このような肉厚構造とすることにより、歩行時に、靴幅内側９が靴幅外側８に比べて屈曲し易くなり、返りも良くなるため、あおり歩行し易くなって、歩行や走行がスムーズにできるようにしてある。   4 (a) to 4 (c), in place of the groove 7 of the first and second embodiments, a bent thin portion 10 is formed by opening a hole (lateral hole) 11 penetrating in the shoe width direction. is there. The lateral holes 11 are gradually formed wider from the shoe width outer side 8 toward the shoe width inner side 9. The depth of the lateral hole 11 is made deeper at the shoe width outer side 8 than at the shoe width inner side 9, and the thickness of the bent thin portion 10 of the shoe sole 1 (total thickness L3 + L4 above and below the hole: FIG. 4 (d)) The shoe width inner side 9 is thinner than the shoe width outer side 8. With such a thick structure, when walking, the inner side 9 of the shoe is easier to bend and return better than the outer side 8 of the shoe, so that it is easier to walk sideways and walk and run smoothly. I can do it.

図示した横穴１１は靴底１の靴幅内側９から靴幅外側８まで連続する長穴であるが、横穴１１は靴底１の靴幅内側９から靴幅外側８の間に断続する断続穴であってもよく、靴底１の靴幅内側９から靴幅外側８の途中まで連続する途中穴であってもよい。また、穴１１の形状は前記した以外であってもよく、例えば、真円形、楕円形などの丸穴、或いは、正方形、長方形などの角穴であってもよい。   The illustrated lateral hole 11 is a long hole that continues from the shoe width inner side 9 to the shoe width outer side 8 of the shoe sole 1, but the lateral hole 11 is an intermittent hole that is intermittently provided between the shoe width inner side 9 and the shoe width outer side 8 of the shoe sole 1. It may be a halfway hole that continues from the shoe width inner side 9 of the shoe sole 1 to the middle of the shoe width outer side 8. The shape of the hole 11 may be other than those described above, and may be, for example, a round hole such as a perfect circle or an ellipse, or a square hole such as a square or a rectangle.

前記穴は、ＭＰ関節接触部付近にだけ設けたり、靴幅外側８から靴底の拇趾球接触部に向けて設けたり、拇趾球接触部を挟んだ爪先側と踵側にだけ設けたりすることもできる。図５に示すように、横穴１１には靴底１よりも屈曲性に優れた材質又は構造の充填材１２を充填しておくこともできる。このような材質、構造の充填材１２を充填することにより、横穴１１内への雨水の進入を防止でき、屈曲性が阻害されない。   The hole is provided only in the vicinity of the MP joint contact portion, provided from the shoe width outer side 8 toward the shoe ball contact portion of the shoe sole, or provided only on the toe side and the shoe side sandwiching the shoe ball contact portion. You can also As shown in FIG. 5, the lateral hole 11 can be filled with a filler 12 having a material or structure superior in flexibility to the shoe sole 1. By filling the filler 12 having such a material and structure, ingress of rainwater into the lateral hole 11 can be prevented, and flexibility is not hindered.

（靴底の実施形態４）
本発明の靴底１の実施形態の他例を、図６（ａ）〜（ｃ）を参照して説明する。この実施形態の靴底１は、多数の突片１３と溝１４を外周面１５に沿って一定間隔で交互に設けて、溝１４と、その溝１４を形成することにより靴底の他の部分よりも肉薄になる屈曲肉薄部１０とにより屈曲部６を形成してある。溝１４は靴底１の外周面１５に開口している。これら溝１４のうち少なくとも土踏まず部４よりも爪先側の溝１４は、靴幅外側８よりも靴幅内側９のものが深く形成されて、屈曲肉薄部１０の肉厚が靴幅外側８の肉厚よりも靴幅内側９の肉厚が薄くなるようにしてある。このような肉厚構造とすることにより、歩行時に屈曲部６の靴幅内側９が靴幅外側８に比べて屈曲し易くなり、返りも良くなるため、あおり歩行し易くなって、歩行や走行がスムーズにできるようにしてある。 (Embodiment 4 of shoe sole)
Another example of the embodiment of the shoe sole 1 of the present invention will be described with reference to FIGS. In the shoe sole 1 of this embodiment, a number of protruding pieces 13 and grooves 14 are alternately provided along the outer peripheral surface 15 at regular intervals, and the grooves 14 and other portions of the shoe sole are formed by forming the grooves 14. The bent portion 6 is formed by the bent thin portion 10 which becomes thinner. The groove 14 opens in the outer peripheral surface 15 of the shoe sole 1. Among these grooves 14, at least the groove 14 on the toe side of the arch portion 4 is formed deeper in the shoe width inner side 9 than the shoe width outer side 8, and the thickness of the bent thin portion 10 is the thickness of the shoe width outer side 8. The thickness of the shoe width inner side 9 is made thinner than the thickness. By having such a thick structure, the inner side 9 of the shoe width of the bent portion 6 is easier to bend and returns better than the outer side 8 of the shoe width during walking. Can be done smoothly.

靴底１の外周の突片（外側突片）１３の内側には十字状の突片（内側突片）１６が数個突設されている。これら外側突片１３、内側突片１６は靴底１のうちＭＰ関節接触部や拇趾球接触部を回避して設けて、靴底１の屈曲性と返りが阻害されないようにするのがよい。外側突片１３の形状、内側突片１６の形状は、円形、角形等の他の形状にすることもできる。   Several cross-shaped projecting pieces (inner projecting pieces) 16 are provided inside the projecting piece (outer projecting piece) 13 on the outer periphery of the shoe sole 1. The outer protrusion 13 and the inner protrusion 16 are preferably provided so as to avoid the MP joint contact portion and the Ryukyu contact portion of the shoe sole 1 so that the flexibility and return of the shoe sole 1 are not hindered. . The shape of the outer protruding piece 13 and the shape of the inner protruding piece 16 may be other shapes such as a circle and a square.

（靴底の実施形態５）
本発明の靴底１の実施形態の他例を、図７（ａ）〜（ｃ）を参照して説明する。図７（ａ）〜（ｃ）の靴底１はその踏み付け部３の肉厚を、靴幅外側８から靴幅内側９に向けて次第に肉薄にして屈曲肉薄部１０とし、その屈曲肉薄部付近と踵部５の裏面に二以上の底突起１７が靴底底面１８より突出するように、靴底１と一体に成型されている。この場合、底突起１７を屈曲肉薄部付近１０付近に踏み付け部３の前後方向に間隔をあけて二以上設けて、それら底突起１７と底突起１７の間（周囲を含む）の空間部２１により屈曲部６を形成してある。この屈曲部６は歩行時に靴底１の靴幅内側９が靴幅外側８に比べて屈曲し易くなり、返りも良くなるため、あおり歩行し易くなって、歩行や走行がスムーズにできるようにしてある。 (Embodiment 5 of the shoe sole)
Another example of the embodiment of the shoe sole 1 of the present invention will be described with reference to FIGS. 7 (a) to 7 (c), the thickness of the stepping portion 3 is gradually reduced from the shoe width outer side 8 toward the shoe width inner side 9 to form a bent thin portion 10, and in the vicinity of the bent thin portion. The sole 5 is molded integrally with the sole 1 so that two or more bottom projections 17 protrude from the sole bottom 18 on the back surface of the heel part 5. In this case, two or more bottom projections 17 are provided in the vicinity of the bent thin portion 10 in the vicinity of the stepped portion 3 with a space in the front-rear direction, and the space portion 21 between the bottom projection 17 and the bottom projection 17 (including the periphery) A bent portion 6 is formed. The bent portion 6 makes it easier to bend the shoe width inner side 9 of the shoe sole 1 than the shoe width outer side 8 during walking and to improve the return, so that it is easy to walk and run smoothly. It is.

前記底突起１７は、靴幅外側８の底突起１７の肉厚よりも靴幅内側９の底突起１７の肉厚を厚くして、靴底１の内面１９から底突起１７の底面２０までの厚さＴ（図７（ｂ）（ｃ））を同じ（略同じを含む。）にして、底突起１７の底面２０が接地したとき、靴底１が靴幅外側８から靴幅内側９に傾斜することなく水平になるようにしてある。   The bottom protrusion 17 is thicker than the thickness of the bottom protrusion 17 on the shoe width outer side 8, so that the thickness of the bottom protrusion 17 on the shoe width inner side 9 is increased from the inner surface 19 of the shoe sole 1 to the bottom surface 20 of the bottom protrusion 17. When the thickness T (FIGS. 7B and 7C) is the same (including substantially the same) and the bottom surface 20 of the bottom projection 17 is grounded, the shoe sole 1 is changed from the shoe width outer side 8 to the shoe width inner side 9. It is designed to be horizontal without inclining.

図７（ａ）に示す底突起１７は底面視円形であるが、底突起１７はこれ以外の形状、例えば亀甲形、ダイヤ形などとすることもできる。いずれの形状の場合も、底突起１７の間（周り）に形成される屈曲部６（底突起１７の底面２０から靴底底面１８までの部分）を靴幅外側８から靴幅内側９に向けて次第に又は段階的に厚くなるようにして、靴幅内側９の方が靴幅外側８に比べて屈曲しやすくなるようにするのが好ましい。底突起１７は拇趾球接触部に向けて或いは拇趾球接触部の前後に設けて、その底突起１７の周囲に屈曲部６を形成することもできる。図６（ｂ）（ｃ）及び図７（ｂ）（ｃ）では屈曲部６の深さの違いを分かりやすくするため、図６（ｂ）（ｃ）では靴幅方向中央付近の十字状の内側突片１６の表記を、図７（ｂ）（ｃ）では靴幅方向中央付近の二つの底突起１７の表記を省略してある。   Although the bottom protrusion 17 shown in FIG. 7A is circular when viewed from the bottom, the bottom protrusion 17 may have other shapes such as a turtle shell shape and a diamond shape. In any case, the bent portion 6 (the portion from the bottom surface 20 of the bottom projection 17 to the bottom surface 18 of the shoe sole) formed between (around) the bottom projections 17 is directed from the shoe width outer side 8 toward the shoe width inner side 9. It is preferable that the shoe width inner side 9 bend more easily than the shoe width outer side 8 so that the shoe width inner side 9 becomes thicker gradually or gradually. The bottom protrusion 17 may be provided toward the front or back of the Ryukyu contact portion, and the bent portion 6 may be formed around the bottom protrusion 17. 6 (b) (c) and 7 (b) (c), in order to make the difference in the depth of the bent portion 6 easier to understand, in FIGS. 6 (b) and 6 (c), a cross-like shape near the center in the shoe width direction is used. The notation of the inner protrusion 16 is omitted in FIGS. 7B and 7C, and the two bottom protrusions 17 near the center in the shoe width direction are omitted.

前記実施形態はいずれも、一枚の靴底に溝だけ又は穴だけを設けた場合であるが、本発明の靴底は、一枚の靴底に溝と穴の双方を設けることもできる。この場合は、一枚の靴底の少なくとも踏み付け部に、その前後方向に間隔をあけて、溝列と穴列を二列以上設け、溝列と穴列を一列置きに交互に設けるとか、数列置きに設けるとかすることもできる。   In any of the above embodiments, only one groove or only a hole is provided in one shoe sole, but the shoe sole of the present invention can also be provided with both a groove and a hole in one shoe sole. In this case, at least the stepping part of one shoe sole is provided with two or more rows of grooves and hole rows at intervals in the front-rear direction, and alternately provided with rows of groove rows and hole rows alternately, or several rows It can also be set up in a place.
