Description

本考案は、シューズに関する。 The present invention relates to shoes.

一般的に、シューズは、アッパー、インソール、ミッドソール、アウトソール等から構成されている。アウトソールは、地面に直接触れる部材であるため、摩耗が生じやすい。したがって、従来から、アウトソールの耐摩耗性の向上が望まれていた。また、アウトソールの重さはシューズ全体の重さに影響するので、アウトソールの軽量性も重要である。 Generally, a shoe is composed of an upper, an insole, a midsole, an outsole and the like. Since the outsole is a member that comes into direct contact with the ground, it is prone to wear. Therefore, it has been conventionally desired to improve the wear resistance of the outsole. In addition, the weight of the outsole affects the weight of the entire shoe, so the lightness of the outsole is also important.

例えば、特許文献１に記載の靴底は、アウトソールの上方にミッドソールが接合されてなる。ミッドソールは、軽量性かつ屈曲性を有するＥＶＡ（エチレン酢酸ビニル共重合体）の発泡体で形成され、アウトソールは、滑りにくく耐摩耗性に優れるサーモプラスチックゴム（ＴＰＲ）で形成され、ミッドソールとアウトソールとが接着剤により接着されている。 For example, the sole described in Patent Document 1 has a midsole bonded above the outsole. The midsole is made of lightweight and flexible EVA (ethylene vinyl acetate copolymer) foam, and the outsole is made of thermoplastic rubber (TPR), which is non-slip and has excellent wear resistance. And the outsole are glued together.

特許文献２に記載の靴底は、ＥＶＡ材からなるミッドソールと、ゴム材からなるアウトソールと、がプレスで一体化された二層構造を有する。 The sole described in Patent Document 2 has a two-layer structure in which a midsole made of EVA material and an outsole made of rubber material are integrated by a press.

Hereinafter, the upper Z1 in the height direction may be referred to as "upper Z1", and the lower Z2 in the height direction may be referred to as "lower Z2".

図１には、本考案の実施形態に係るシューズ１の外観が示されている。シューズ１は、アッパー３と、ソール４と、を備える。 FIG. 1 shows the appearance of the shoe 1 according to the embodiment of the present invention. The shoe 1 includes an upper 3 and a sole 4.

（アッパー）
アッパー３は、足を覆って保護する。アッパー３の材料は、特に限定されず、天然皮革、合成皮革、人工皮革等の皮、天然繊維又は化学繊維を用いた布地、ゴム等が例示される。 (upper)
The upper 3 covers and protects the foot. The material of the upper 3 is not particularly limited, and examples thereof include leathers such as natural leather, synthetic leather, and artificial leather, fabrics using natural fibers or chemical fibers, and rubber.

アッパー３は、前方Ｙ１に位置する前方部３Ａと、後方Ｙ２に位置する後方部３Ｂと、を有する。前方部３Ａと後方部３Ｂとは、例えば縫い合わされることにより、連結される。 The upper 3 has a front portion 3A located at the front Y1 and a rear portion 3B located at the rear Y2. The front portion 3A and the rear portion 3B are connected, for example, by being sewn together.

アッパー３は、足を収容するための内部空間３１を囲むように形成される。内部空間３１は、後方Ｙ２に位置して足を挿入するための後方側空間３１Ａと、後方側空間３１Ａの前方Ｙ１に位置する前方側空間３１Ｂとからなる。 The upper 3 is formed so as to surround the internal space 31 for accommodating the foot. The internal space 31 is composed of a rear side space 31A located in the rear Y2 for inserting a foot and a front side space 31B located in the front Y1 of the rear side space 31A.

後方側空間３１Ａと前方側空間３１Ｂとは、連続している。また、後方側空間３１Ａは、足を挿入するために上方Ｚ１が覆われていないが、前方側空間３１Ｂは、ベロ２と、ベロ２の上方に配置されるシューレース３３と、によって上方Ｚ１が覆われる。 The rear side space 31A and the front side space 31B are continuous. Further, the rear side space 31A is not covered with the upper Z1 for inserting the foot, but the front side space 31B is covered with the upper Z1 by the tongue 2 and the shoelace 33 arranged above the tongue 2. Be covered.

ベロ２は、シューレース３３の高さ方向下方Ｚ２において前方側空間３１Ｂを覆い、主に足の甲に接触する部材である。 The tongue 2 is a member that covers the front space 31B in the lower Z2 in the height direction of the shoelace 33 and mainly contacts the instep.

ベロ２は、アッパー３の前方部３Ａと連続的かつ一体的に形成されている。したがって、ベロ２の材料は、アッパー３と同一であり、天然皮革、合成皮革、人工皮革等の皮、天然繊維又は化学繊維を用いた布地、ゴム等が例示される。なお、ベロ２は、アッパー３と必ずしも一体的に形成されなくてもよく、アッパー３と別体に形成されてアッパー３に縫合等の手段で固定されてもよい。 The tongue 2 is formed continuously and integrally with the front portion 3A of the upper 3. Therefore, the material of the tongue 2 is the same as that of the upper 3, and examples thereof include leathers such as natural leather, synthetic leather, and artificial leather, fabrics using natural fibers or chemical fibers, and rubber. The tongue 2 does not necessarily have to be integrally formed with the upper 3, and may be formed separately from the upper 3 and fixed to the upper 3 by means such as suturing.

（ソール）
ソール４は、インソール５と、アウトソール６と、を備える。なお、ソール４は、インソール５とアウトソール６との間にミッドソールを備えてもよい。ソール４は、接着等の手段によりアッパー３に固定される。 (Sole)
The sole 4 includes an insole 5 and an outsole 6. The sole 4 may be provided with a midsole between the insole 5 and the outsole 6. The sole 4 is fixed to the upper 3 by means such as adhesion.

（インソール）
インソール５は、アウトソール６上に配置される。インソール５は、足底が触れる部材であるため、通気性、吸水性、クッション性等に優れる材料からなることが好ましい。 (insole)
The insole 5 is arranged on the outsole 6. Since the insole 5 is a member that the sole of the foot touches, it is preferably made of a material having excellent breathability, water absorption, cushioning property, and the like.

（アウトソール）
図１〜６に示されるように、アウトソール６は、前方Ｙ１側に配置され、爪先部を含む前部６１と、後方Ｙ２側に配置され、踵部を含む後部６３と、を有する。後部６３は、いわゆるヒールである。前部６１の後方Ｙ２側の端部は、下方Ｚ２に延びる段部６５を介して、後部６３の前方Ｙ１側の端部と接続する。 (Outsole)
As shown in FIGS. 1 to 6, the outsole 6 has a front portion 61 arranged on the front Y1 side and including the toe portion, and a rear portion 63 arranged on the rear Y2 side and including the heel portion. The rear 63 is a so-called heel. The rear Y2 end of the front 61 is connected to the front Y1 end of the rear 63 via a step 65 extending downward Z2.

アウトソール６は、第一部材７と第二部材８とを含む。後に詳述するように、異なる部材である第一部材７及び第二部材８が互いに連結されることにより、アウトソール６は構成される。 The outsole 6 includes a first member 7 and a second member 8. As will be described in detail later, the outsole 6 is formed by connecting the first member 7 and the second member 8 which are different members to each other.

第一部材７は、第二部材８よりも耐摩耗性が高い材料からなり、第二部材８は、第一部材７よりも軽量である材料からなる。例えば、第一部材７は、ラバーであり、第二部材８は、ＥＶＡ（エチレン酢酸ビニル共重合体）である。 The first member 7 is made of a material having higher wear resistance than the second member 8, and the second member 8 is made of a material that is lighter than the first member 7. For example, the first member 7 is rubber, and the second member 8 is EVA (ethylene vinyl acetate copolymer).

図２（ａ）〜（ｃ）には、下方Ｚ２から見た第一部材７及び第二部材８の底面図が示されている。図２（ａ）には、第一部材７及び第二部材８が連結された状態が示され、図２（ｂ）には、第一部材７の底面７０が示され、図２（ｃ）には、第二部材８の底面８０が示される。図５には、下方Ｚ２から見たアウトソール６の斜視図が示されている。 2 (a) to 2 (c) show bottom views of the first member 7 and the second member 8 as seen from the lower Z2. FIG. 2A shows a state in which the first member 7 and the second member 8 are connected, and FIG. 2B shows a bottom surface 70 of the first member 7, which is shown in FIG. 2C. Shows the bottom surface 80 of the second member 8. FIG. 5 shows a perspective view of the outsole 6 as seen from the lower Z2.

図３（ａ）〜（ｃ）には、上方Ｚ１から見た第一部材７及び第二部材８の上面図が示されている。図３（ａ）には、第一部材７及び第二部材８が連結された状態が示され、図３（ｂ）には、第一部材７の上面７６が示され、図３（ｃ）には、第二部材８の上面８６が示される。図６には、上方Ｚ１から見たアウトソール６の斜視図が示されている。 3 (a) to 3 (c) are top views of the first member 7 and the second member 8 as viewed from above Z1. FIG. 3 (a) shows a state in which the first member 7 and the second member 8 are connected, and FIG. 3 (b) shows the upper surface 76 of the first member 7, which is shown in FIG. 3 (c). Shows the upper surface 86 of the second member 8. FIG. 6 shows a perspective view of the outsole 6 as viewed from above Z1.

図４には、幅方向Ｘから見たアウトソール６の側面図が示されている。 FIG. 4 shows a side view of the outsole 6 as viewed from the width direction X.

アウトソール６は、その接地面に第一部材７が配置されることにより耐摩耗性を向上しつつ、その全周に第二部材８が配置されることにより軽量性を向上している。ここで、「接地面」とは、シューズ１の通常の使用状態（使用者がシューズ１を着用している状態）において、アウトソール６の底面のうち地面に接触する面を意味する。したがって、「接地面」は、アウトソール６の底面の全体とは限らない。 The outsole 6 is improved in wear resistance by arranging the first member 7 on the ground contact surface thereof, and is improved in lightness by arranging the second member 8 on the entire circumference thereof. Here, the “contact patch” means a surface of the bottom surface of the outsole 6 that comes into contact with the ground in a normal use state of the shoe 1 (a state in which the user is wearing the shoe 1). Therefore, the "ground plane" is not necessarily the entire bottom surface of the outsole 6.

以下、アウトソール６を構成する第一部材７及び第二部材８について、詳述する。 Hereinafter, the first member 7 and the second member 8 constituting the outsole 6 will be described in detail.

（第一部材）
第一部材７は、前方Ｙ１に配置され、爪先部を含む前部７１と、後方Ｙ２に配置され、踵部を含む後部７３と、を有する。前部７１及び後部７３は一体部材である。 (First member)
The first member 7 has a front portion 71 which is arranged at the front Y1 and includes a toe portion, and a rear portion 73 which is arranged at the rear Y2 and includes a heel portion. The front portion 71 and the rear portion 73 are integral members.

図２（ｂ）に示されるように、第一部材７の底面７０は、前部７１の底面７１Ａと、後部７３の底面７３Ａと、を含む。前部７１の底面７１Ａの後方Ｙ２の端部は、下方Ｚ２に延びる段部７５を介して、後部７３の底面の前方Ｙ１の端部と接続する。したがって、前部７１の底面７１Ａの後方Ｙ２の端部よりも、後部７３の底面７３Ａの前方Ｙ１の端部の方が、下方Ｚ２に位置する。 As shown in FIG. 2B, the bottom surface 70 of the first member 7 includes a bottom surface 71A of the front portion 71 and a bottom surface 73A of the rear portion 73. The end of the rear Y2 of the bottom surface 71A of the front portion 71 is connected to the end of the front Y1 of the bottom surface of the rear portion 73 via a step portion 75 extending downward Z2. Therefore, the end of the front Y1 of the bottom 73A of the rear 73 is located at the lower Z2 than the end of the rear Y2 of the bottom 71A of the front 71.

前部７１の底面７１Ａは、着用者の足底の形状に沿うように、長手方向Ｙにおける略中央部が下方Ｚ２に膨らむ湾曲した形状に形成される。前部７１の底面７１Ａには、下方Ｚ２に突出する複数の突起部７２が形成される。本例では、六個の突起部７２が長手方向Ｙに並んで配置されており、長手方向Ｙにおいて隣り合う突起部７２の間には隙間が設けられる。複数の突起部７２の底面は、平面状に形成される。なお、突起部７２の個数や形状は、シューズ１の種類や用途等に基づき適宜変更される。 The bottom surface 71A of the front portion 71 is formed in a curved shape in which a substantially central portion in the longitudinal direction Y bulges downward Z2 so as to follow the shape of the sole of the wearer. A plurality of protrusions 72 projecting downward Z2 are formed on the bottom surface 71A of the front portion 71. In this example, the six protrusions 72 are arranged side by side in the longitudinal direction Y, and a gap is provided between the protrusions 72 adjacent to each other in the longitudinal direction Y. The bottom surfaces of the plurality of protrusions 72 are formed in a flat shape. The number and shape of the protrusions 72 are appropriately changed based on the type and use of the shoe 1.

前部７１の底面７１Ａにおいて最も下方Ｚ２に突出する部分は複数の突起部７２であるので、シューズ１が地面に接地する際、これら複数の突起部７２が地面と接触する。すなわち、複数の突起部７２が、アウトソール６の接地面を構成する。 Since the portion of the bottom surface 71A of the front portion 71 that protrudes most downward to Z2 is a plurality of protrusions 72, when the shoe 1 touches the ground, the plurality of protrusions 72 come into contact with the ground. That is, the plurality of protrusions 72 form the ground contact surface of the outsole 6.

後部７３の底面７３Ａは、前部７１と段部７５を介して接続する内側部７７と、内側部７７を囲むように、内側部７７の幅方向内方Ｘ１、幅方向外方Ｘ２、及び後方Ｙ２に位置する外周部７８と、を含む。 The bottom surface 73A of the rear portion 73 surrounds the inner portion 77 connected to the front portion 71 via the step portion 75, and the inner portion 77 in the width direction inward X1, the width direction outer side X2, and the rear portion so as to surround the inner portion 77. Includes an outer peripheral portion 78 located at Y2.

内側部７７には、前部７１の底面７１Ａと同様に、下方Ｚ２に突出する複数の突起部７２が形成されている。本例では、三個の突起部７２が長手方向Ｙに並んで配置されており、長手方向Ｙにおいて隣り合う突起部７２の間には隙間が設けられる。複数の突起部７２の底面は、平面状に形成される。なお、突起部７２の個数や形状は、シューズ１の種類や用途等に基づき適宜変更される。 Similar to the bottom surface 71A of the front portion 71, a plurality of protrusions 72 projecting downward Z2 are formed on the inner portion 77. In this example, the three protrusions 72 are arranged side by side in the longitudinal direction Y, and a gap is provided between the protrusions 72 adjacent to each other in the longitudinal direction Y. The bottom surfaces of the plurality of protrusions 72 are formed in a flat shape. The number and shape of the protrusions 72 are appropriately changed based on the type and use of the shoe 1.

外周部７８は、平面状である。外周部７８の下方Ｚ２方向の高さは、内側部７７に形成された複数の突起部７２の下方Ｚ２方向の高さと略一致する。したがって、複数の突起部７２の底面と外周部７８とによって、平面が形成される。 The outer peripheral portion 78 is flat. The height of the outer peripheral portion 78 in the lower Z2 direction substantially coincides with the height of the plurality of protrusions 72 formed on the inner portion 77 in the lower Z2 direction. Therefore, a flat surface is formed by the bottom surfaces of the plurality of protrusions 72 and the outer peripheral portions 78.

後部７３の底面７３Ａにおいて最も下方Ｚ２に突出する部分は、複数の突起部７２と外周部７８であるので、シューズ１が地面に接地する際、これら複数の突起部７２と外周部７８とが地面と接触する。すなわち、複数の突起部７２と外周部７８とが、アウトソール６の接地面を構成する。 Since the portion of the bottom surface 73A of the rear portion 73 that protrudes most downward to Z2 is the plurality of protrusions 72 and the outer peripheral portion 78, when the shoe 1 touches the ground, the plurality of protrusions 72 and the outer peripheral portion 78 are on the ground. Contact with. That is, the plurality of protrusions 72 and the outer peripheral portion 78 form the ground contact surface of the outsole 6.

図３（ｂ）に示されるように、第一部材７の上面７６は、前部７１の上面７１Ｂと、後部７３の上面７３Ｂと、を含む。 As shown in FIG. 3B, the upper surface 76 of the first member 7 includes the upper surface 71B of the front portion 71 and the upper surface 73B of the rear portion 73.

前部７１の上面７１Ｂは、着用者の足底の形状に沿うように、長手方向Ｙにおける略中央部が下方Ｚ２に膨らむ湾曲した形状に形成される。 The upper surface 71B of the front portion 71 is formed in a curved shape in which a substantially central portion in the longitudinal direction Y bulges downward Z2 so as to follow the shape of the sole of the wearer.

後部７３の上面７３Ｂは、内側に形成された溝部７９と、溝部７９の幅方向内方Ｘ１、幅方向外方Ｘ２、及び後方Ｙ２に位置する外周部７４と、を有する。溝部７９は、底面７３Ａの内側部７７（図２（ｂ）参照）に対応する位置（高さ方向Ｚから見て重なる位置）に設けられる。溝部７９は、前部７１の上面７１Ｂよりも下方Ｚ２に凹む凹溝であり、後述する第二部材８の凸部８７が嵌合可能である。そのため、溝部７９は、後述する第二部材８の凸部８７と略同一形状又は僅かに大きな相似形状となるように形成される。また、外周部７４は、略平面状である。 The upper surface 73B of the rear portion 73 has a groove portion 79 formed inside, an inner side X1 in the width direction, an outer side X2 in the width direction, and an outer peripheral portion 74 located at the rear Y2 of the groove portion 79. The groove portion 79 is provided at a position (a position where the groove portion 79 overlaps when viewed from the height direction Z) corresponding to the inner portion 77 (see FIG. 2B) of the bottom surface 73A. The groove portion 79 is a concave groove recessed in Z2 below the upper surface 71B of the front portion 71, and the convex portion 87 of the second member 8 described later can be fitted. Therefore, the groove portion 79 is formed so as to have substantially the same shape as the convex portion 87 of the second member 8 described later or a slightly larger similar shape. Further, the outer peripheral portion 74 is substantially flat.

（第二部材）
第二部材８は、前方Ｙ１側に配置され、爪先部を含む前部８１と、後方Ｙ２側に配置され、踵部を含む後部８３と、を有する。前部８１及び後部８３は一体部材である。 (Second member)
The second member 8 has a front portion 81 arranged on the front Y1 side and including the toe portion, and a rear portion 83 arranged on the rear Y2 side and including the heel portion. The front portion 81 and the rear portion 83 are integral members.

前部８１の底面８１Ａは、着用者の足底の形状に沿うように、長手方向Ｙにおける略中央部が下方Ｚ２に膨らむ湾曲した形状に形成される。 The bottom surface 81A of the front portion 81 is formed in a curved shape in which a substantially central portion in the longitudinal direction Y bulges downward Z2 so as to follow the shape of the sole of the wearer.

前部８１の底面８１Ａは、内側に形成される凹部８２と、凹部８２を囲むように、凹部８２の幅方向内方Ｘ１、幅方向外方Ｘ２、及び前方Ｙ１に位置する外周部８４と、を含む。 The bottom surface 81A of the front portion 81 includes a recess 82 formed inside, an outer peripheral portion 84 located at the inner side X1 in the width direction, the outer side X2 in the width direction, and the front Y1 of the recess 82 so as to surround the recess 82. including.

凹部８２は、第一部材７の前部７１の外形と略同一形状又は僅かに大きな相似形状となるように形成される。凹部８２は、上方Ｚ１に向かって凹む凹溝であり、第一部材７の前部７１が嵌合可能である。外周部８４は、略平面状に形成される。 The recess 82 is formed so as to have substantially the same shape as the outer shape of the front portion 71 of the first member 7 or a slightly larger similar shape. The recess 82 is a recess groove that is recessed toward the upper Z1, and the front portion 71 of the first member 7 can be fitted. The outer peripheral portion 84 is formed in a substantially flat shape.

後部８３の底面８３Ａは、内側に形成された凸部８７と、凸部８７を囲むように、凸部８７の幅方向内方Ｘ１、幅方向外方Ｘ２、及び後方Ｙ２に位置する外周部８８と、を含む。 The bottom surface 83A of the rear portion 83 has a convex portion 87 formed inside and an outer peripheral portion 88 located at the inner X1 in the width direction, the outer X2 in the width direction, and the rear Y2 of the convex portion 87 so as to surround the convex portion 87. And, including.

凸部８７は、前部８１の凹部８２の溝底面８２Ａよりも、下方Ｚ２に突出する。また、凸部８７は、第一部材７の上面７３Ｂに設けられた溝部７９（図３（ｂ）参照）と略同一形状又は僅かに小さな相似形状となるように形成される。これにより、凸部８７は溝部７９に嵌合可能である。 The convex portion 87 projects downward Z2 from the groove bottom surface 82A of the concave portion 82 of the front portion 81. Further, the convex portion 87 is formed so as to have substantially the same shape as the groove portion 79 (see FIG. 3B) provided on the upper surface 73B of the first member 7 or a slightly smaller similar shape. As a result, the convex portion 87 can be fitted into the groove portion 79.

外周部８８は、略平面状に形成される。なお、前部８１の底面８１Ａの外周部８４と、後部８３の底面８３Ａの外周部８８と、は滑らかに接続している。これら二つの外周部８４，８８によって、第二部材８の底面８０の外周部が構成される。 The outer peripheral portion 88 is formed in a substantially flat shape. The outer peripheral portion 84 of the bottom surface 81A of the front portion 81 and the outer peripheral portion 88 of the bottom surface 83A of the rear portion 83 are smoothly connected. These two outer peripheral portions 84 and 88 form the outer peripheral portion of the bottom surface 80 of the second member 8.

図３（ｃ）に示されるように、第二部材８の上面８６は、前部８１の上面８１Ｂと、後部８３の上面８３Ｂと、を含む。前部８１の上面８１Ｂは、着用者の足底の形状に沿うように、長手方向Ｙにおける略中央部が下方Ｚ２に膨らむ湾曲した形状に形成される。後部８３の上面８３Ｂは、略平面状に形成される。 As shown in FIG. 3C, the upper surface 86 of the second member 8 includes the upper surface 81B of the front portion 81 and the upper surface 83B of the rear portion 83.

The upper surface 83B of the rear portion 83 is formed in a substantially flat shape.

（第一部材と第二部材の連結）
第一部材７と第二部材８とは、互いに嵌め合わされることにより、連結される。連結方法をより詳細に説明すると、先ず、第一部材７に対して上方Ｚに第二部材８を位置させ、これら第一部材７及び第二部材８を高さ方向Ｚに互いに接近させる。そうすると、第一部材７の上面７６と、第二部材８の底面８０と、が互いに接触する。 (Connecting the first member and the second member)
The first member 7 and the second member 8 are connected by being fitted to each other. To explain the connecting method in more detail, first, the second member 8 is positioned above the first member 7 and the first member 7 and the second member 8 are brought close to each other in the height direction Z. Then, the upper surface 76 of the first member 7 and the bottom surface 80 of the second member 8 come into contact with each other.

そして、第二部材８の前部８１の底面８１Ａの凹部８２と、第一部材７の前部７１と、が嵌合する。また、第一部材７の後部７３の上面７３Ｂの溝部７９と、第二部材８の後部８３の底面８３Ａの凸部８７と、が嵌合する。また、第一部材７の後部７３の上面７３Ｂの外周部７４と、第二部材８の後部８３の底面８３Ａの外周部８８と、が接触する。 Then, the recess 82 of the bottom surface 81A of the front portion 81 of the second member 8 and the front portion 71 of the first member 7 are fitted. Further, the groove portion 79 of the upper surface 73B of the rear portion 73 of the first member 7 and the convex portion 87 of the bottom surface 83A of the rear portion 83 of the second member 8 are fitted. Further, the outer peripheral portion 74 of the upper surface 73B of the rear portion 73 of the first member 7 and the outer peripheral portion 88 of the bottom surface 83A of the rear portion 83 of the second member 8 come into contact with each other.

このようにして、第一部材７と第二部材８とが連結され、アウトソール６が構成される。なお、第一部材７の上面７６と第二部材８の底面８０とが互いに嵌合又は接触し合う部分には、接着剤が配置されることで、連結力が高められる。 In this way, the first member 7 and the second member 8 are connected to form the outsole 6. In addition, the connecting force is enhanced by arranging the adhesive in the portion where the upper surface 76 of the first member 7 and the bottom surface 80 of the second member 8 are fitted or in contact with each other.

図３（ａ）、図４、図６に示されるように、第一部材７と第二部材８とが連結されて構成されたアウトソール６においては、第一部材７の上方Ｚ１が第二部材８によって覆われる。すなわち、アウトソール６の上面全体が、第二部材８の上面８６によって構成される。 As shown in FIGS. 3A, 4 and 6, in the outsole 6 formed by connecting the first member 7 and the second member 8, the upper Z1 of the first member 7 is the second. Covered by member 8. That is, the entire upper surface of the outsole 6 is composed of the upper surface 86 of the second member 8.

そして、アウトソール６の前部６１の外周部及び後部６３の外周部に、連続的に第二部材８が配置されており、第二部材８がアウトソール６の外周を規定している。したがって、アウトソール６の全周に第二部材８が配置される。アウトソール６の全周という広い範囲に第二部材８が配置されるので、アウトソール６の軽量性が高められる。また、アウトソール６の全周に第二部材８が配置されるので、重量バランスが良好である。 The second member 8 is continuously arranged on the outer peripheral portion of the front portion 61 of the outsole 6 and the outer peripheral portion of the rear portion 63, and the second member 8 defines the outer peripheral portion of the outsole 6. Therefore, the second member 8 is arranged on the entire circumference of the outsole 6. Since the second member 8 is arranged over a wide range of the entire circumference of the outsole 6, the weight of the outsole 6 is enhanced. Further, since the second member 8 is arranged on the entire circumference of the outsole 6, the weight balance is good.

また、第一部材７の上方Ｚ１が第二部材８によって覆われているので、軽量な第二部材８がアウトソール６の広い範囲に配置され、軽量性が向上する。さらに、第二部材８は軽量であるが第一部材７に比べて耐摩耗性が低いため、第二部材８が地面から遠くに配置されて地面に接触しにくい本実施形態の構成は好ましい。 Further, since the upper Z1 of the first member 7 is covered by the second member 8, the lightweight second member 8 is arranged in a wide range of the outsole 6, and the lightness is improved. Further, since the second member 8 is lightweight but has lower wear resistance than the first member 7, the configuration of the present embodiment in which the second member 8 is arranged far from the ground and does not easily come into contact with the ground is preferable.

一方、図２（ａ）、図４、図５に示されるように、アウトソール６の底面は、第一部材７の底面７０と、第二部材８の底面８０の一部と、によって構成される。より詳細には、アウトソール６の底面は、第一部材７の前部７１の底面７１Ａと、第二部材８の前部８１の底面８１Ａの外周部８４と、第一部材７の後部７３の底面７３Ａと、によって構成される On the other hand, as shown in FIGS. 2A, 4 and 5, the bottom surface of the outsole 6 is composed of a bottom surface 70 of the first member 7 and a part of the bottom surface 80 of the second member 8. To. More specifically, the bottom surface of the outsole 6 includes a bottom surface 71A of the front portion 71 of the first member 7, an outer peripheral portion 84 of the bottom surface 81A of the front portion 81 of the second member 8, and a rear portion 73 of the first member 7. Consists of bottom 73A and

ここで、アウトソール６の前部６１において、第一部材７の複数の突起部７２は、第二部材８の外周部８４よりも、下方Ｚ２に突出している。したがって、第一部材７の突起部７２は、地面に接触する接地面を構成する。一方、第二部材８の外周部８４は、接地面を構成しない。 Here, in the front portion 61 of the outsole 6, the plurality of protrusions 72 of the first member 7 project downward Z2 from the outer peripheral portion 84 of the second member 8. Therefore, the protrusion 72 of the first member 7 constitutes a ground contact surface in contact with the ground. On the other hand, the outer peripheral portion 84 of the second member 8 does not form a ground plane.

また、アウトソール６の後部６３においては、第一部材７の外周部７８及び複数の突起部７２の高さ方向Ｚにおける高さが略等しく形成されているので、これら、外周部７８及び複数の突起部７２が接地面を構成する。 Further, in the rear portion 63 of the outsole 6, since the heights of the outer peripheral portion 78 of the first member 7 and the plurality of protrusions 72 in the height direction Z are formed to be substantially equal, these, the outer peripheral portion 78 and the plurality of protrusions 72 are formed. The protrusion 72 constitutes the ground plane.

このように、アウトソール６の接地面には、耐摩耗性が高い第一部材７が配置される。一方、耐摩耗性が比較的低い第二部材８は、アウトソール６の接地面には配置されず、アウトソール６の全周に配置され、通常の使用状態では地面に接触しない。したがって、シューズ１の靴底が擦り減ること、特に、耐摩耗性が比較的低い第二部材８が擦り減ることを効果的に抑制できる。 In this way, the first member 7 having high wear resistance is arranged on the ground contact surface of the outsole 6. On the other hand, the second member 8 having a relatively low wear resistance is not arranged on the ground contact surface of the outsole 6, but is arranged on the entire circumference of the outsole 6 and does not come into contact with the ground under normal use conditions. Therefore, it is possible to effectively prevent the sole of the shoe 1 from being worn away, and in particular, the second member 8 having a relatively low wear resistance from being worn down.

また、本実施形態においては、アウトソール６の前部６１の底面には、外周部に第二部材８の外周部８４が配置され、第二部材８の外周部８４に囲まれた内側部に第一部材７が配置される。第一部材７の突起部７２は、第二部材８よりも下方Ｚ２に突出することにより、地面と接触する接地面を構成する。したがって、アウトソール６の前部６１の底面において、耐摩耗性が高い第一部材７によって、接地面を構成することができる。また、軽量の第二部材８は、アウトソール６の前部６１の外周部という広い範囲に配置されるので、軽量性が向上される。 Further, in the present embodiment, on the bottom surface of the front portion 61 of the outsole 6, the outer peripheral portion 84 of the second member 8 is arranged on the outer peripheral portion, and the outer peripheral portion 84 of the second member 8 is surrounded by the outer peripheral portion 84. The first member 7 is arranged. The protrusion 72 of the first member 7 projects downward to Z2 below the second member 8 to form a ground contact surface in contact with the ground. Therefore, on the bottom surface of the front portion 61 of the outsole 6, the ground contact surface can be formed by the first member 7 having high wear resistance. Further, since the lightweight second member 8 is arranged in a wide range of the outer peripheral portion of the front portion 61 of the outsole 6, the lightness is improved.

また、アウトソール６の後部６３の外周部は、上部（上方Ｚ１）に第二部材８が配置され、下部（下方Ｚ２）に第一部材７が配置される、二層構造である。さらに、アウトソール６の後部６３の底面の全体に、第一部材７が配置される。したがって、アウトソール６の後部６３の底面において、耐摩耗性が高い第一部材７によって、接地面を構成することができる。また、軽量であるが耐摩耗性が比較的低い第二部材８は、下方Ｚ２の耐摩耗性の高い第一部材７に覆われて地面と接することがないので、軽量性と耐摩耗性とを両立させることできる。 Further, the outer peripheral portion of the rear portion 63 of the outsole 6 has a two-layer structure in which the second member 8 is arranged in the upper portion (upper Z1) and the first member 7 is arranged in the lower portion (lower Z2). Further, the first member 7 is arranged on the entire bottom surface of the rear portion 63 of the outsole 6. Therefore, on the bottom surface of the rear portion 63 of the outsole 6, the ground contact surface can be formed by the first member 7 having high wear resistance. Further, since the second member 8 which is lightweight but has relatively low wear resistance is covered with the first member 7 having high wear resistance in the lower Z2 and does not come into contact with the ground, it is considered to be lightweight and wear resistant. Can be compatible.

また、耐摩耗性に優れる材料は、一般にクッション性が劣るところ、本実施形態においては、アウトソール６の足裏と対向する面が全て第二部材８によって覆われているので、クッション性に優れた良好な履き心地を実現することができる。 Further, a material having excellent wear resistance is generally inferior in cushioning property, but in the present embodiment, the surface of the outsole 6 facing the sole of the foot is entirely covered by the second member 8, so that the material has excellent cushioning property. It is possible to realize a good comfort.

（第二実施形態）
次に、第二実施形態に係るアウトソール６について、図７（ａ）〜図９を参照して説明する。 (Second Embodiment)
Next, the outsole 6 according to the second embodiment will be described with reference to FIGS. 7A to 9.

第二実施形態のアウトソール６の前部６１の構成は、第一実施形態のアウトソール６の前部６１の構成と略同一であるので、図面に同じ符号を付すことでその説明を省略する。 Since the configuration of the front portion 61 of the outsole 6 of the second embodiment is substantially the same as the configuration of the front portion 61 of the outsole 6 of the first embodiment, the description thereof will be omitted by adding the same reference numerals to the drawings. ..

第一実施形態においては、アウトソール６の後部６３の外周部が、第一部材７及び第二部材８からなる二層構造であったが、第二実施形態においては、アウトソール６の後部６３の外周部には、第一部材７が配置されず、第二部材８のみが配置される。また、アウトソール６の後部の底面には、第二部材８に囲まれた内側部に、第一部材７が配置される。そして、第一部材７が第二部材８よりも突出することにより接地面を構成する。この第二実施形態のアウトソール６は、以下に説明する第一部材７及び第二部材８が連結されることにより構成される。 In the first embodiment, the outer peripheral portion of the rear portion 63 of the outsole 6 has a two-layer structure composed of the first member 7 and the second member 8, but in the second embodiment, the rear portion 63 of the outsole 6 The first member 7 is not arranged on the outer peripheral portion of the above, and only the second member 8 is arranged. Further, on the bottom surface of the rear portion of the outsole 6, the first member 7 is arranged in an inner portion surrounded by the second member 8. Then, the first member 7 protrudes from the second member 8 to form a ground contact surface. The outsole 6 of the second embodiment is configured by connecting the first member 7 and the second member 8 described below.

図７（ｂ）に示されるように、第一部材７の後部７３の底面７３Ａは、内側部７７と、複数の突起部７２と、を含む。すなわち、第一部材７の後部７３の底面７３Ａは、第一実施形態の底面７３Ａ（図２（ｂ）参照）から外周部７８が取り除かれた構成とされる。 As shown in FIG. 7B, the bottom surface 73A of the rear portion 73 of the first member 7 includes an inner portion 77 and a plurality of protrusions 72. That is, the bottom surface 73A of the rear portion 73 of the first member 7 has a configuration in which the outer peripheral portion 78 is removed from the bottom surface 73A (see FIG. 2B) of the first embodiment.

図８（ｂ）に示されるように、第一部材７の後部７３の上面７３Ｂは、前部７１の上面７１Ｂよりも下方Ｚ２に凹む溝部７９を含む。溝部７９は、後述する第二部材８の凸部８７と略同一形状又は僅かに大きな相似形状となるように形成される。すなわち、第一部材７の後部７３の上面７３Ｂは、第一実施形態の上面７３Ｂ（図３（ｂ）参照）から外周部７４と溝部７９の後方Ｚ２の一部とが取り除かれた構成とされる。 As shown in FIG. 8B, the upper surface 73B of the rear portion 73 of the first member 7 includes a groove portion 79 recessed in Z2 below the upper surface 71B of the front portion 71. The groove portion 79 is formed so as to have substantially the same shape as the convex portion 87 of the second member 8 described later or a slightly larger similar shape. That is, the upper surface 73B of the rear portion 73 of the first member 7 has a configuration in which the outer peripheral portion 74 and a part of the rear Z2 of the groove portion 79 are removed from the upper surface 73B (see FIG. 3B) of the first embodiment. To.

このように、本実施形態の第一部材７の後部７３は、第一実施形態の第一部材７の後部７３から外周部と後方Ｚ２の一部が除かれた構成とされる。 As described above, the rear portion 73 of the first member 7 of the present embodiment has a configuration in which the outer peripheral portion and a part of the rear Z2 are removed from the rear portion 73 of the first member 7 of the first embodiment.

図７（ｃ）に示されるように、第二部材８の後部８３の底面８３Ａは、内側に形成された凸部８７と、凸部８７を囲むように、凸部８７の幅方向内方Ｘ１、幅方向外方Ｘ２、及び後方Ｙ２に位置する外周部８８と、を含む。 As shown in FIG. 7C, the bottom surface 83A of the rear portion 83 of the second member 8 has a convex portion 87 formed inside and the convex portion 87 inward X1 in the width direction so as to surround the convex portion 87. , And an outer peripheral portion 88 located at the outer X2 in the width direction and the rear Y2.

なお、第一実施形態との対応関係を分かりやすくするため、符号８７で示された部分を第一実施形態に合わせて「凸部８７」と記載したが、凸部８７の下方Ｚ２方向の高さは、溝底面８２Ａよりも高いが、外周部８８よりも低くなっている（外周部８８を基準にすれば、凸部８７は凹部となっている）。 In order to make it easier to understand the correspondence with the first embodiment, the portion indicated by reference numeral 87 is described as "convex portion 87" in accordance with the first embodiment, but the height of the convex portion 87 in the downward Z2 direction is described. Although it is higher than the groove bottom surface 82A, it is lower than the outer peripheral portion 88 (the convex portion 87 is a concave portion based on the outer peripheral portion 88).

ここで、第二部材８の後部８３の底面８３Ａの外周部８８（図９参照）の高さ方向Ｚにおける位置が、第一実施形態の外周部８８（図４参照）よりも下方Ｚ２とされる。すなわち、本実施形態では、外周部８８の下方Ｚ２に、第一部材７が配置されないため、その分、外周部８８が下方Ｚ２まで延ばされている。 Here, the position of the outer peripheral portion 88 (see FIG. 9) of the bottom surface 83A of the rear portion 83 of the second member 8 in the height direction Z is set to Z2 below the outer peripheral portion 88 (see FIG. 4) of the first embodiment. To. That is, in the present embodiment, since the first member 7 is not arranged in the lower Z2 of the outer peripheral portion 88, the outer peripheral portion 88 is extended to the lower Z2 by that amount.

したがって、後部８３の底面８３Ａの外周部８８は、前部８１の底面８１Ａの外周部８４よりも下方Ｚ２に位置し、前部８１の底面８１Ａの外周部８４と段部８９を介して接続している。 Therefore, the outer peripheral portion 88 of the bottom surface 83A of the rear portion 83 is located below the outer peripheral portion 84 of the bottom surface 81A of the front portion 81, and is connected to the outer peripheral portion 84 of the bottom surface 81A of the front portion 81 via the step portion 89. ing.

図８（ｃ）に示されるように、第二部材８の後部８３の上面８３Ｂは、略平面状に形成される。 As shown in FIG. 8C, the upper surface 83B of the rear portion 83 of the second member 8 is formed in a substantially flat shape.

このように、本実施形態では第一実施形態と比べて、第一部材７の後部７３において外周部が取り除かれる一方で、第二部材８の後部の外周部が下方Ｚ２に向かって肉厚とされる。 As described above, in the present embodiment, as compared with the first embodiment, the outer peripheral portion of the rear portion 73 of the first member 7 is removed, while the outer peripheral portion of the rear portion of the second member 8 is thickened toward the lower Z2. Will be done.

第一部材７と第二部材８とが連結される際には、先ず、第一部材７に対して上方Ｚに第二部材８を位置させ、これら第一部材７及び第二部材８を高さ方向Ｚに互いに接近させる。そうすると、第一部材７の上面７６と、第二部材８の底面８０と、が互いに接触する。 When the first member 7 and the second member 8 are connected, first, the second member 8 is positioned above the first member 7 and the first member 7 and the second member 8 are raised. Bring them closer to each other in the longitudinal direction Z. Then, the upper surface 76 of the first member 7 and the bottom surface 80 of the second member 8 come into contact with each other.

そして、第二部材８の前部８１の底面８１Ａの凹部８２と、第一部材７の前部７１と、が嵌合する。また、第一部材７の後部７３の上面７３Ｂの溝部７９と、第二部材８の後部８３の上面８３Ｂの凸部８７と、が嵌合する。 Then, the recess 82 of the bottom surface 81A of the front portion 81 of the second member 8 and the front portion 71 of the first member 7 are fitted. Further, the groove portion 79 of the upper surface 73B of the rear portion 73 of the first member 7 and the convex portion 87 of the upper surface 83B of the rear portion 83 of the second member 8 are fitted.

このように構成されたアウトソール６の前部の構成は、上述の通り、第一実施形態と同一である。すなわち、アウトソール６の前部６１の底面において、第一部材７の複数の突起部７２は、第二部材８の外周部８４よりも、下方Ｚ２に突出している。したがって、図９に示されるように、第一部材７の突起部７２は、地面に接触する接地面を構成する。一方、第二部材８の外周部８４は、接地面を構成しない。 The configuration of the front portion of the outsole 6 configured in this way is the same as that of the first embodiment as described above. That is, on the bottom surface of the front portion 61 of the outsole 6, the plurality of protrusions 72 of the first member 7 project downward Z2 from the outer peripheral portion 84 of the second member 8. Therefore, as shown in FIG. 9, the protrusion 72 of the first member 7 constitutes a ground contact surface in contact with the ground. On the other hand, the outer peripheral portion 84 of the second member 8 does not form a ground plane.

一方、アウトソール６の後部６３の底面においては、第一部材７の内側部７７に形成された複数の突起部７２が、第二部材８の外周部８８よりも下方Ｚ２に突出するように形成される（図９参照）。したがって、第一部材７の突起部７２は、地面に接触する接地面を構成する。一方、第二部材８の外周部８８は、接地面を構成しない。 On the other hand, on the bottom surface of the rear portion 63 of the outsole 6, a plurality of protrusions 72 formed on the inner portion 77 of the first member 7 are formed so as to project downward Z2 from the outer peripheral portion 88 of the second member 8. (See FIG. 9). Therefore, the protrusion 72 of the first member 7 constitutes a ground contact surface in contact with the ground. On the other hand, the outer peripheral portion 88 of the second member 8 does not form a ground plane.

このように、アウトソール６の後部６３の外周部には、第二部材８が配置され、アウトソール６の後部６３の底面には、第二部材８に囲まれた内側部に、第一部材７が配置される。そして、第一部材７の複数の突起部７２が第二部材８の外周部８８よりも突出することにより接地面を構成する。 As described above, the second member 8 is arranged on the outer peripheral portion of the rear portion 63 of the outsole 6, and the first member is arranged on the bottom surface of the rear portion 63 of the outsole 6 in the inner portion surrounded by the second member 8. 7 is arranged. Then, the plurality of protrusions 72 of the first member 7 project from the outer peripheral portion 88 of the second member 8 to form a ground contact surface.

したがって、本実施形態のアウトソール６によれば、接地面には、第二部材８が配置されず、第一部材７が配置されるので、耐摩耗性が確保できる。さらに、本実施形態のアウトソール６によれば、アウトソール６の後部６３の外周部には、第一部材７が配置されず第二部材８が配置されるので、第一実施形態に比べて、アウトソール６中で第二部材８が占める体積が大きくなり、さらなる軽量化が可能である。 Therefore, according to the outsole 6 of the present embodiment, the second member 8 is not arranged on the ground contact surface, but the first member 7 is arranged, so that wear resistance can be ensured. Further, according to the outsole 6 of the present embodiment, the first member 7 is not arranged but the second member 8 is arranged on the outer peripheral portion of the rear portion 63 of the outsole 6, so that the second member 8 is arranged as compared with the first embodiment. , The volume occupied by the second member 8 in the outsole 6 is increased, and further weight reduction is possible.
