本発明の実施例を、図１〜図６に基づき説明する。図１、２、４、５においてＡは本発明の履物であり、履物Ａは、概略的に、アウトソール１と、インソール３と、補強部材２とを備えている。また、必要に応じて種々の形状の甲被部材４が設けられる。   An embodiment of the present invention will be described with reference to FIGS. In FIGS. 1, 2, 4, and 5, A is the footwear of the present invention, and the footwear A generally includes an outsole 1, an insole 3, and a reinforcing member 2. Moreover, the upper member 4 of various shapes is provided as needed.

アウトソール１は、歩行時に地面ｇに接地し、接地時の衝撃を吸収するものであり、このアウトソール１の底面は、図２に示したように、該アウトソール１のつま先部１ａ（足ｆのつま先に対応する部位）においてアウトソール１の長手方向の前端側に向かって上方に傾斜し、歩行時に地面ｇに接地する第１の傾斜部１ｘと、アウトソール１の踵部１ｃ（足ｆの踵に対応する部位）においてアウトソール１の長手方向の後端側に向かって上方に傾斜し、歩行時に地面ｇに接地する第２の傾斜部１ｙとを有している。   The outsole 1 makes contact with the ground g during walking and absorbs the impact at the time of grounding. The bottom of the outsole 1 has a toe portion 1a (foot) of the outsole 1 as shown in FIG. a first inclined portion 1x that is inclined upward toward the front end side in the longitudinal direction of the outsole 1 at a portion corresponding to the toe of f, and a heel portion 1c (foot) of the outsole 1 that contacts the ground g during walking. and a second inclined portion 1y that inclines upward toward the rear end side in the longitudinal direction of the outsole 1 and contacts the ground g during walking.

前述の第１の傾斜部１ｘおよび第２の傾斜部１ｙの形状は、平面であっても、曲面であっても構わないが、履物Ａを履いて直立したとき、少なくともアウトソール１のつま先部１ａおよび踵部１ｃが地面ｇから離間する傾斜角度を有している必要がある。第１の傾斜部１ｘおよび第２の傾斜部１ｙの形状が曲面である場合には下方に向かって凸状となるように設けるのが好ましい。   The shape of the first inclined portion 1x and the second inclined portion 1y may be a flat surface or a curved surface, but when the footwear A is worn and standing upright, at least the toe portion of the outsole 1 1a and the collar part 1c need to have the inclination angle which leaves | separates from the ground g. When the shape of the 1st inclination part 1x and the 2nd inclination part 1y is a curved surface, it is preferable to provide so that it may become convex shape below.

なお、アウトソール１は、地面への接地時の衝撃を吸収できるように、例えば、ポリウレタンやエチレン酢酸ビニル共重合体（ＥＶＡ）の発泡体、合成ゴム、生ゴム、ポリ塩化ビニル（ＰＶＣ）など、柔軟性を有する部材により構成される。   In addition, the outsole 1 can absorb the impact at the time of the ground contact, for example, a polyurethane, an ethylene vinyl acetate copolymer (EVA) foam, synthetic rubber, raw rubber, polyvinyl chloride (PVC), etc. It is comprised by the member which has a softness | flexibility.

インソール３は、アウトソール１の上方に設けられるものであり、履物Ａを履いたときに足裏が直接接触するため、履物の履き心地が良くなるように、例えば、ポリウレタンやエチレン酢酸ビニル共重合体（ＥＶＡ）の発泡体、合成皮革、フェルトなど、柔軟性を有する部材が用いられる。   The insole 3 is provided above the outsole 1, and since the soles come into direct contact with the footwear A, for example, polyurethane or ethylene vinyl acetate co-polymerized so as to improve the comfort of the footwear. A flexible member such as a foam (EVA) foam, synthetic leather, or felt is used.

また、このインソール３は、外観を良くしたり、足裏の滑り止めを行う等のために、被覆部材（図示せず）により被覆する構成としてもよい。   Further, the insole 3 may be configured to be covered with a covering member (not shown) in order to improve the appearance or prevent the sole from slipping.

補強部材２は、履物を履いたときに体重がかかってもアウトソール１の第１の傾斜部１ｘおよび第２の傾斜部１ｙが下方に変形するのを防止するものであり、アウトソール１とインソール３のいずれの部材よりも硬い部材であって、図１および図２に示したように、アウトソール１とインソール３との間に位置し、アウトソール１の土踏まず部１ｂ（足ｆの土踏まずに対応する部位）からアウトソール１のつま先部１ａに向かって延びると共にアウトソール１の土踏まず部１ｂからアウトソール１の踵部１ｃに向かって延びるものである。   The reinforcing member 2 prevents the first inclined portion 1x and the second inclined portion 1y of the outsole 1 from being deformed downward even when the weight is applied when the footwear is worn. As shown in FIGS. 1 and 2, the member is harder than any member of the insole 3, and is located between the outsole 1 and the insole 3, and the arch portion 1 b (the arch of the foot f) of the outsole 1. 2) toward the toe portion 1a of the outsole 1 and extends from the arch portion 1b of the outsole 1 toward the collar portion 1c of the outsole 1.

この補強部材２は、図３に示したように、例えば、アウトソール１の上面に補強部材２を嵌め込む凹部１ｄを設けて該凹部１ｄに嵌着してもよく、特に、アウトソール１が発泡樹脂で形成される場合にあっては、成形後の発泡樹脂を確実に補強することができる点で有効である。また、補強部材２を凹部１ｄに嵌着したとき、補強部材２の外周上縁と凹部１ｄの内周上縁との間に段差がないように形成するのが好ましく、更には、補強部材２の外表面２ａとアウトソール１の凹部１ｄの外周上面１ｅとが同面であるのがより好ましい。ここで、アウトソール１と補強部材２とインソール３とは、例えば、公知の接着剤により接着して固定される。   As shown in FIG. 3, for example, the reinforcing member 2 may be fitted in the concave portion 1 d by providing a concave portion 1 d for fitting the reinforcing member 2 on the upper surface of the outsole 1. In the case of being formed of a foamed resin, it is effective in that the foamed resin after molding can be reliably reinforced. In addition, when the reinforcing member 2 is fitted into the recess 1d, it is preferable that there is no step between the outer peripheral upper edge of the reinforcing member 2 and the inner peripheral upper edge of the concave 1d. It is more preferable that the outer surface 2a of the outer periphery and the outer peripheral upper surface 1e of the recess 1d of the outsole 1 are the same surface. Here, the outsole 1, the reinforcing member 2, and the insole 3 are fixed by bonding with a known adhesive, for example.

なお、補強部材２は、履物を履いて歩行してもアウトソール１の第１の傾斜部１ｘおよび第２の傾斜部１ｙの傾斜を保持できる程度に硬く変形し難い部材であり、例えば、ステンレス鋼、アルミニウム、チタン合金などの金属材料や、ＡＢＳ樹脂、ＥＶＡ樹脂、炭素樹脂、ポリエチレン、ゴム系樹脂（ＴＰＲ）などの強度の高いプラスチック材料を用いることができる。また、履物の軽量化を図ることができる点では、プラスチック材料を用いるのが好ましい。   The reinforcing member 2 is a member that is hard and difficult to be deformed to such an extent that the inclination of the first inclined portion 1x and the second inclined portion 1y of the outsole 1 can be maintained even when walking while wearing footwear. Metal materials such as steel, aluminum, and titanium alloys, and high-strength plastic materials such as ABS resin, EVA resin, carbon resin, polyethylene, and rubber-based resin (TPR) can be used. In addition, it is preferable to use a plastic material in that the footwear can be reduced in weight.

次に、上述した履物Ａの作用について図４に基づき説明する。図４は履物Ａを履いて歩行したときの履物Ａと地面ｇの位置関係を示したものであり、歩行する際の経時的な変化を図４（ａ）、（ｂ）、（ｃ）の順で図示している。図４（ａ）は、足ｆを前方に踏み出してアウトソール１が地面ｇに接地したときの状態を示しており、通常は履物Ａが斜めの状態でアウトソール１の踵部１ｃから着地するが、この踵部１ｃに第２の傾斜部１ｙが設けられている分、地面ｇに対して踵部１ｃが略平行に近い状態で接地する。   Next, the effect | action of the footwear A mentioned above is demonstrated based on FIG. FIG. 4 shows the positional relationship between the footwear A and the ground g when walking with the footwear A, and the changes over time when walking are shown in FIGS. 4 (a), 4 (b), and 4 (c). They are shown in order. FIG. 4 (a) shows a state where the foot f is stepped forward and the outsole 1 is in contact with the ground g. Usually, the footwear A is landed from the heel part 1c of the outsole 1 in an oblique state. However, since the second inclined portion 1y is provided on the collar portion 1c, the collar portion 1c is grounded in a state of being substantially parallel to the ground g.

そして、身体が前方に移動するに従い、履物Ａが揺りかごのように前方に斜倒し、アウトソール１の第２の傾斜部１ｙが上昇して地面ｇから離間すると共にアウトソール１のつま先部１ｘが下降し、図４（ｂ）に示したように、履物Ａが略水平な状態になる。   As the body moves forward, the footwear A tilts forward like a cradle, the second inclined portion 1y of the outsole 1 rises away from the ground g, and the toe portion 1x of the outsole 1 As shown in FIG. 4B, the footwear A is in a substantially horizontal state.

そして、更に身体が前方に移動すると、引き続き履物Ａが揺りかごのように前方に斜倒し、図４（ｃ）に示したように、アウトソール１のつま先部１ａが接地するが、このつま先部１ａに第１の傾斜部１ｘが設けられている分、履物Ａが前端を下方にして斜倒しても地面ｇに対してつま先部１ａが略平行に近い状態で接地する。   When the body moves further forward, the footwear A continues to tilt forward like a cradle and the toe portion 1a of the outsole 1 is grounded as shown in FIG. 4C. Since the first inclined portion 1x is provided, the toe portion 1a is grounded with the toe portion 1a being substantially parallel to the ground g even if the footwear A tilts with the front end downward.

このとき、本発明の履物Ａにあっては、アウトソール１とインソール３のいずれの部材よりも硬い補強部材２が、アウトソール１とインソール３との間に位置し、アウトソール１の土踏まず部１ｂからアウトソール１のつま先部１ａに向かって延びると共にアウトソール１の土踏まず部１ｂからアウトソール１の踵部１ｃに向かって延びているため、履物を履いたときの体重によりインソール３が下方に向かって押圧されたとしても、この硬い補強部材２によりアウトソール１の第１の傾斜部１ｘおよび第２の傾斜部１ｙが下方に変形するのを防止してこれら第１および第２の傾斜部の傾斜を保持することができ、歩行に際しアウトソール１の底面が踵部１ｃからつま先部１ａに向かって揺りかごのように順次地面ｇに接地することにより、歩行者の足裏にかかる体重を踵からつま先に向かって円滑に移動させてスムーズな歩行を行うことができる。   At this time, in the footwear A of the present invention, the reinforcing member 2 that is harder than any member of the outsole 1 and the insole 3 is located between the outsole 1 and the insole 3, and the arch portion of the outsole 1 1b extends toward the toe portion 1a of the outsole 1 and extends from the arch portion 1b of the outsole 1 toward the heel portion 1c of the outsole 1, so that the insole 3 is lowered downward depending on the weight when the footwear is worn. Even when pressed toward the bottom, the hard reinforcing member 2 prevents the first inclined portion 1x and the second inclined portion 1y of the outsole 1 from being deformed downward, and the first and second inclined portions. The bottom of the outsole 1 is grounded to the ground g sequentially like a cradle from the heel part 1c toward the toe part 1a during walking. The weight applied to the sole of the ascetic smoothly moved toward the toe from the heel can be carried out in a smooth gait.

ところで、上述した図１〜図４では、補強部材２は、アウトソール１の土踏まず部１ｂからアウトソール１のつま先部１ａに向かって延びると共にアウトソール１の土踏まず部１ｂからアウトソール１の踵部１ｃに向かって延びるものの内、アウトソール１の上面の一部に設けたものを例示したが、図６（ａ）に示したように、この補強部材２をアウトソール１のつま先部１ａの前端から踵部１ｃの後端に亘って設ける構成としたり、アウトソール１の幅寸法に亘って設ける構成（図示せず）としてもよい。   1 to 4 described above, the reinforcing member 2 extends from the arch portion 1b of the outsole 1 toward the toe portion 1a of the outsole 1, and the heel portion of the outsole 1 from the arch portion 1b of the outsole 1. Among the members extending toward 1c, those provided on a part of the upper surface of the outsole 1 are illustrated. As shown in FIG. 6A, the reinforcing member 2 is connected to the front end of the toe portion 1a of the outsole 1. It is good also as a structure provided over the rear end of the collar part 1c, or a structure (not shown) provided over the width dimension of the outsole 1.

また、アウトソール１の形状は、図５に示したように、該アウトソール１の底面において、第１の傾斜部１ｘと第２の傾斜部１ｙとの間に略水平な水平面を有する水平部１ｚを設ける構成としてもよい。この水平部１ｚを設けることにより、履物Ａを履いた状態で直立静止する場合であっても、水平部１ｚの水平面が地面ｇに平面的に接地することにより、安定して直立静止することができる。   Further, as shown in FIG. 5, the shape of the outsole 1 is a horizontal part having a substantially horizontal horizontal plane between the first inclined part 1 x and the second inclined part 1 y on the bottom surface of the outsole 1. It is good also as a structure which provides 1z. By providing the horizontal portion 1z, even when the footwear A is worn and standing upright, the horizontal surface of the horizontal portion 1z can be stably upright and stationary by being grounded to the ground g. it can.

さらに、補強部材２の形状は、図１、図３、図６（ａ）に示したように、アウトソール１の上縁の形状に沿わせたものとしてもよいが、図６（ｂ）に示したように平面視樹枝状に形成したり、図６（ｃ）に示したように、一または二以上の孔２ｃを穿設して（図６（ｃ）では二以上の孔２ｃが設けられた補強部材２を例示）平面視中抜き状に形成したりしてもよい。   Furthermore, the shape of the reinforcing member 2 may be adapted to the shape of the upper edge of the outsole 1 as shown in FIGS. 1, 3 and 6A.
