Description
本発明は、靴底、履物及び履物の靴底の変形方法に係り、特に、歩き易く、しかも疲れにくい靴底、履物及び履物の靴底の変形方法に関する。 The present invention relates to a shoe sole, footwear, and a method for deforming a shoe sole of a footwear, and more particularly, to a shoe sole that is easy to walk and is less tiring, and a method for deforming a shoe sole of a footwear.
従来、転がるような動きで、高齢者でも容易に歩けるものとして、「ロッカー靴」と称される履物がある。 Conventionally, there is a footwear called “rocker shoes” that can be easily walked even by elderly people in a rolling motion.
しかしながら、上記「ロッカー靴」と称される履物においては、靴底のロッカー形状を維持するために、靴底が曲がりにくくできており、特に、踵離地時、靴底が屈曲せず、
踵の動きに追随しない為、踵が脱げ易くなるという問題が生じた。
However, in the footwear referred to as the above "rocker shoes", in order to maintain the shape of the rocker of the shoe sole, the shoe sole is difficult to bend.
Since the movement of the kite does not follow, there is a problem that the kite is easy to take off.
本発明は、上記実情を考慮してなされた靴底、履物及び履物の靴底の変形方法を提供することを目的とする。 An object of the present invention is to provide a shoe sole, footwear, and a method for deforming the shoe sole of the footwear in consideration of the above situation.
本発明に係わる靴底は、踏みつけ部から爪先部にかけて、ロッカー形状を備える靴底であって、前記靴底は、屈曲方向に指向性を有していることを特徴とするものである。
屈曲方向に指向性を有するとは、前記靴底の踵部と前記靴底の爪先部が近づく下に凸方向の変形を許容し、前記靴底の前記踵部と前記靴底の前記爪先部が遠ざかる上に凸方向の変形を規制することである。
The shoe sole according to the present invention is a shoe sole having a rocker shape from a stepping portion to a toe portion, and the shoe sole has directivity in a bending direction.
Having a directivity in the bending direction means that deformation in a convex direction is allowed under the heel portion of the shoe sole and the toe portion of the shoe sole, and the heel portion of the shoe sole and the toe portion of the shoe sole. It is to restrict the deformation in the convex direction while moving away.
本発明に係わる靴底において、前記靴底の踏みつけ部の屈曲性を高めることで、前記靴底の踵部と前記靴底の爪先部が近づく下に凸方向に変形し易くし、踵が接地面から離れる時に、靴底が踵から離間することを防いで、踵の動きに靴底が追随して屈曲するため、歩き易く、疲れにくい履物を得ることができる。
しかし、屈曲性を高めることで、前記靴底の前記踵部と前記靴底の前記爪先部が遠ざかる上に凸方向の変形もしやすくなり、前記靴底のロッカー機能が損なわれてしまうため、その変形を規制する必要がある。
前記靴底の上面において、前記靴底の屈曲範囲、もしくは全面に、屈曲性の良い非伸縮性の部材を貼り合せることにより、前記靴底の踵部と前記靴底の爪先部が近づく下に凸方向の変形を許容し、前記靴底の前記踵部と前記靴底の前記爪先部が遠ざかる上に凸方向の変形を規制することができる。
In the shoe sole according to the present invention, by increasing the flexibility of the stepping portion of the shoe sole, the shoe sole and the toe portion of the shoe sole are easily deformed in a convex direction so that the shoe comes into contact with the shoe sole. When the shoe sole leaves the ground, the shoe sole is prevented from being separated from the heel, and the shoe sole follows the movement of the heel and bends. Therefore, it is possible to obtain footwear that is easy to walk and is not fatigued.
However, by increasing the flexibility, the heel portion of the shoe sole and the toe portion of the shoe sole move away from each other, and it is easy to deform in a convex direction, and the rocker function of the shoe sole is impaired. It is necessary to regulate deformation.

The deformation in the convex direction is allowed, and the deformation in the convex direction can be restricted while the heel portion of the shoe sole and the toe portion of the shoe sole move away.
靴底の踏みつけ部の屈曲性を高めるための手段として、前記靴底の屈曲範囲において、靴底上面に靴底の長手方向を横断する方向に溝部を設けている。
溝の位置を狙いの屈曲位置に配置することで、その溝部を起点として靴底が屈曲し、靴底の足への追随性が良くなる。
As a means for improving the flexibility of the shoe tread part, a groove is provided on the upper surface of the shoe sole in a direction crossing the longitudinal direction of the shoe sole in the bending range of the shoe sole.
By arranging the position of the groove at a target bending position, the shoe sole bends from the groove portion as a starting point, and the followability of the shoe sole to the foot is improved.
靴底の踏みつけ部の屈曲性を高めるための手段として、前記靴底の屈曲範囲において、靴底底面に靴底の長手方向を横断する方向に溝部を設けている。
さらに、靴底底面の溝部は、前記靴底上面の溝部の位置に対して、対になって配置されることにより、狙いの屈曲位置での屈曲性をより高めることができ、また、溝の幅や長さ、深さ等を変えることで、屈曲度合を調整することも可能である。
As a means for improving the flexibility of the shoe sole stepping portion, a groove portion is provided in the shoe sole bottom surface in a direction crossing the longitudinal direction of the shoe sole in the bending range of the shoe sole.
Furthermore, the groove portion on the bottom surface of the shoe sole is arranged in a pair with respect to the position of the groove portion on the upper surface of the shoe sole, so that the flexibility at the target bending position can be further improved. The degree of bending can be adjusted by changing the width, length, depth, and the like.
前記靴底の底面に設けられた溝部の下側に、伸縮性が高く、圧縮性の低い部材を貼り合せることで、前記靴底の踵部と前記靴底の爪先部が近づく下に凸方向の変形を許容し、前記靴底の前記踵部と前記靴底の前記爪先部が遠ざかる上に凸方向の変形を規制することができる。 By sticking a member having high elasticity and low compressibility to the lower side of the groove portion provided on the bottom surface of the shoe sole, a convex direction is formed so that the heel portion of the shoe sole and the toe portion of the shoe sole approach each other.

A method of deforming a shoe sole, footwear and a shoe sole of footwear according to an embodiment of the present invention will be described with reference to the drawings.
F shown in FIG. 1 is footwear, and the footwear F includes a shoe sole G and an upper 3 having a rocker shape.
As shown in FIG. 2, the shoe sole G includes an outsole 1 and a midsole 2, and an insole 4 is bonded to the upper surface of the midsole 2.
That is, the shoe sole G of the footwear F has the outsole 1, the midsole 2, and the midsole 4 sequentially from the bottom to the top.
The outsole 1 is bonded to a part or the whole of the bottom surface of the midsole 2, and the material of the outsole 1 is, for example, a highly elastic and low-compression synthetic rubber or natural rubber, EVA (ethylene. (Vinyl acetate copolymer resin), PU (polyurethane), etc. are used, and the hardness of the outsole 1 is preferably in the range of 50 to 80 in the Asker rubber hardness meter C type.
The insole 4 is bonded to the upper surface of the midsole 2, and the bending range of the shoe sole (the bending range 1C between the tread portion 1A and the toe portion 1B), or the entire upper surface of the shoe sole, A non-stretchable member 5 having good flexibility is used.
When the member 5 is used only for the bending range of the sole G, as shown in FIG. 3, it is used as an intermediate member of the midsole 4, and the heel side member 41 and the toe side member 42 of the midsole 4 Connected.
Since the member 5 has good bendability, it can be used with the heel portion 4X of the insole 4 and the middle portion 4 without interfering with the bendability of the sole, even when used on the entire upper surface of the shoe sole or only on the bend range. The deformation in the convex direction is allowed under the toe portion 4Y of the bottom 4 approaching.
Further, since the member 5 is non-stretchable, the member 5 is in a tensioned state when trying to deform in the convex direction while the collar portion 4X of the midsole 4 and the toe portion 4Y of the midsole 4 are away from each other. Therefore, the protrusion 4 </ b> X of the midsole 4 and the toe part 4 </ b> Y of the midsole 4 move away from each other, and deformation in the convex direction is restricted.
The member 5 is made of, for example, a non-stretchable fabric having good flexibility and made of natural fiber or chemical fiber.
For example, the heel part side member 41 and the toe part side member 42 of the insole 4 are impregnated paper, cardboard, synthetic resin, leather, etc., which are widely used as the core material of the insole of shoes. Is used.
As shown in FIG. 3, the midsole 2 has a recessed portion 20 that protrudes downward on the side closer to the toe than the heel, and the midsole 4 is an intermediate member (the buttock side member 41 of the midsole 4). And the intermediate member (the member 5 between the buttocks side member 41 of the midsole 4 and the toe side member 42) is non-stretchable and bent. The intermediate member (the member 5 between the buttocks side member 41 and the toe side member 42 of the midsole 4) is located on the recess 20 (see FIG. 3), and the intermediate member (midsole 4), the member 5) between the heel part member 41 and the toe part side member 42 allows deformation in the convex direction below the heel part 4X of the insole 4 and the toe part 4Y of the insole 4 Deformation in the convex direction is restricted while the flange 4X of the bottom 4 and the toe portion 4Y of the midsole 4 move away.
As shown in FIG. 3, it is bonded to the insole 4 (inside the insole 4, 4 in FIG. 3, the insole 4 located below), and the insole (inside the insole 4, 4 in FIG. A cover body (the middle bottom 4 in the middle bottoms 4 and 4 in FIG. 3) that covers the upper surface of the bottom bottom 4) is provided, and this cover body (the middle bottom 4 in FIG. 3, 4, the middle bottom 4) located above is non-stretchable and flexible like the intermediate member (the member 5 between the buttocks side member 41 and the toe side member 42 of the midsole 4). ing.
In the present embodiment, two members are provided with the insole 4 and 4 in FIG. 3, but in some cases, the insole 4 located in the upper part of the insole 4 and 4 in FIG. Of the insole 4, 4, only the insole 4 located below may be used, or the inside insole 4, 4 in FIG. Of the midsole 4, 4, only the midsole 4 positioned above may be used.
図２及び図３に示すミッドソール２は、アウトソール１と中底４の間に位置し、踏み付け部１Ｃにて曲がりやすくなるように、靴底Ｇの長手方向を横断する方向に溝部２Ｍが複数設けられている。
溝部２Ｍは、靴底Ｇの屈曲範囲にて、ミッドソール２の上面と底面に設けられ、上面の溝と底面の溝の位置が、対になることで、より一層、靴底の屈曲性が良好になり、踵が接地面Ｈから離れる際、足の踵が靴底Ｇから離間することを防いで、踵の動きに靴底Ｇが追随してより屈曲して、歩き易く、しかも、疲れにくい履物Ｆを得ることができる。
ミッドソール２の材質は、例えば、ＰＵ（ポリウレタン）、ＥＶＡ（エチレン・酢酸ビニル共重合樹脂）、合成ゴム等が適用可能である。
つまり、靴底Ｇの屈曲範囲において、ミッドソール２の上面に、ミッドソール２の長手方向を横断する方向に上面溝部２Ｍを、ミッドソール２の底面に、ミッドソール２の長手方向を横断する方向に底面溝部２Ｍを、それぞれ設け、平面視、上面溝部２Ｍの下に底面溝部２Ｍが位置している。
The midsole 2 shown in FIGS. 2 and 3 is located between the outsole 1 and the insole 4 and has a groove 2M in a direction crossing the longitudinal direction of the shoe sole G so as to be easily bent at the stepping portion 1C. A plurality are provided.
The groove portion 2M is provided on the upper surface and the bottom surface of the midsole 2 in the bending range of the shoe sole G, and the position of the groove on the upper surface and the groove on the bottom surface becomes a pair, thereby further improving the flexibility of the shoe sole. When the heel moves away from the ground contact surface H, the heel of the foot is prevented from separating from the sole G, the sole G follows the movement of the heel and bends more easily, and it is easy to walk. A difficult footwear F can be obtained.
As the material of the midsole 2, for example, PU (polyurethane), EVA (ethylene / vinyl acetate copolymer resin), synthetic rubber, or the like is applicable.
That is, in the bending range of the sole G, the upper surface groove portion 2M is formed on the upper surface of the midsole 2 in a direction crossing the longitudinal direction of the midsole 2, and the longitudinal direction of the midsole 2 is intersected on the bottom surface of the midsole 2. Are provided with bottom groove portions 2M, and the bottom groove portions 2M are located below the top groove portions 2M in plan view.
屈曲性を高めたミッドソール２に対し、靴底Ｇの踏み付け部から爪先部が靴底底面方向へ落ち込まないように、ミッドソール２の底面側の溝部２Ｍを橋架けしてまたぐ、または被うようにアウトソール１を貼り合せている。
アウトソール１は、高伸縮性、低圧縮性の合成ゴム等でできているため、靴底が屈曲する際には、溝部の広がりに合わせて伸張し、屈曲性を阻害しないうえ、靴底の踏み付け部から爪先部へ下側方向への力が働く際には、アウトソール１が圧縮し難い為、変形を抑制する。
また、図２乃至図４に示すように、アウトソール１の底面において、ミッドソール２の底面に設置された溝部２Ｍの直下に、溝部１Ｍを設けることで、アウトソール１の屈曲位置での伸長性をより良好にすることができ、靴底Ｇの屈曲性を向上することが可能になる。
つまり、平面視、ミッドソール２の上面溝部２Ｍの下にミッドソール２の底面溝部２Ｍ及びアウトソール１の底面溝部１Ｍが位置している。
The midsole 2 with enhanced flexibility is bridged or covered with a groove 2M on the bottom side of the midsole 2 so that the toe portion does not fall from the stepped part of the sole G toward the bottom of the shoe sole. The outsole 1 is bonded together.
Since the outsole 1 is made of synthetic rubber having high elasticity and low compressibility, when the shoe sole bends, the outsole 1 stretches in accordance with the spread of the groove portion, and does not hinder the flexibility. When a downward force is applied from the stepping portion to the toe portion, the outsole 1 is difficult to compress, and therefore deformation is suppressed.
Further, as shown in FIGS. 2 to 4, in the bottom surface of the outsole 1, the groove portion 1 </ b> M is provided immediately below the groove portion 2 </ b> M installed on the bottom surface of the midsole 2, thereby extending the outsole 1 at the bent position. Therefore, the flexibility of the shoe sole G can be improved.
That is, in plan view, the bottom groove 2M of the midsole 2 and the bottom groove 1M of the outsole 1 are located below the top groove 2M of the midsole 2.
靴底Ｇ、およびそれを備えた履物Ｆによれば、上述した構造により、靴底Ｇの屈曲方向に指向性を持ち、靴底Ｇの踵部と靴底の爪先部が近づく下に凸方向の変形を許容する為、中底の踵部４Ｘと中底の爪先部４Ｙが近づく下に凸方向に変形し易くして、踵が接地面Ｈから離れる時に、踵が中底４から離間することを防いで、踵の動きに靴底が追随して屈曲して、歩き易く、しかも、疲れにくい履物Ｆを得ることができる。（図５及び図７参照）
また、中底４の踵部４Ｘと中底４の爪先部４Ｙが遠ざかる上に凸方向の変形を規制する為、接地面Ｈを蹴り出す時、靴底の底面方向への変形を防いで、ロッカー形状を維持し、荷重を推進力に変えて歩き易く、しかも、疲れにくい履物を得ることができる。（図５及び図６参照）
According to the shoe sole G and the footwear F provided with the shoe G, the structure described above has directivity in the bending direction of the shoe sole G, and the convex direction in which the heel portion of the shoe sole G approaches the toe portion of the shoe sole. In order to allow deformation of the insole, the insole heel part 4X and the insole toe part 4Y are easily deformed in a convex direction, and the heel is separated from the insole 4 when the heel is separated from the ground contact surface H. Therefore, it is possible to obtain the footwear F which is easy to walk and is not easily fatigued by bending the shoe sole following the movement of the heel. (See FIGS. 5 and 7)
In addition, in order to restrict the deformation in the convex direction while the heel part 4X of the insole 4 and the toe part 4Y of the insole 4 move away, when the ground contact surface H is kicked out, the deformation in the bottom direction of the shoe sole is prevented, It is possible to obtain a footwear that maintains a rocker shape, is easy to walk by changing the load to a propulsive force, and is less likely to get tired. (See FIGS. 5 and 6)
履物Ｆの靴底Ｇの変形方法の靴底Ｇは、靴底Ｇの踵部と靴底Ｇの爪先部が近づく下に凸方向の変形を許容し、靴底Ｇの踵部と靴底Ｇの爪先部が遠ざかる上に凸方向の変形を規制する。
つまり、靴底Ｇによれば、靴底Ｇの屈曲方向に指向性があり、靴底Ｇのみで靴底爪先部の下側方向への変形を規制することが可能になるため、アッパー３のデザインや材質、例えばオープントゥのデザインやストレッチ素材など、選択の自由度が増える。
The sole G of the deformation method of the sole G of the footwear F allows deformation in a convex direction as the heel portion of the shoe sole G approaches the toe portion of the sole G, and the heel portion of the sole G and the sole G The tip of the toe part moves away and the deformation in the convex direction is restricted.
In other words, according to the shoe sole G, the bending direction of the shoe sole G is directional, and deformation of the shoe sole toe portion in the lower direction can be restricted only by the shoe sole G. Design and materials, such as open-toe design and stretch material, will increase your freedom of choice.
