Definitions
- the present invention relates to a shoe, which has comfort to wear and which is capable of efficiently converting grounding impact into a thrust force occurring upon push off and is suitable for running or walking.
- a cushion material 24 is provided to an entire sole member 22 of a shoe 20 so as to reduce grounding impact applied to a sole of foot and obtain flexibility and a thrust force occurring upon push off.
- the shoe having such structure is disclosed in, for example, Patent Literature 1 (Japanese Laid-open Patent Publication No. 2002-85104 ).
- the inventor of the present invention has invented a shoe, which is capable of storing grounding impact as energy and radiating the stored energy as a repulsion force when pushing off by a front foot part and is capable of reducing fatigue and burden of the foot and running or walking efficiently, and the shoe is disclosed in Patent Literature 2 (Japanese Laid-open Patent Publication No. 2010-162318 ). Concretely, as shown in Fig.
- a hard stepping plate 31 and a hard grounding plate 34 are connected, by a connecting section 34 of a heel part (a rear foot part), with a suitable clearance 33, so that a plate spring 35, which returns the clearance 33 to an original state when an external force for narrowing the clearance 33 is applied, is formed, and the plate spring 35 is attached to a bottom part of the shoe at a front foot part of the hard stepping plate 31.
- an object of the present invention is to provide a shoe, which is light and capable of improving cushioning properties and a thrust force occurring upon push off without sacrificing comfort to wear and which has a simple structure and can be mass-produced.
- the shoe of the present invention comprises: a shoe body into which a foot is inserted; a hard plate covering a necessary area on a bottom side of the shoe body in a length direction and being fixed to the bottom side of the shoe body only at a necessary location including a position of a front foot part; and cushion materials being attached to at least both end parts of a ground contact side of the hard plate in the length direction.
- the necessary area is the entire shoe body in the length direction. With this structure, options of attachment positions of the cushion materials can be increased.
- the necessary area is an area from the front foot part to a heel part except a toe part.
- the cushion material is attached to a position on the bottom side of the shoe body which corresponds to the toe part.
- the hard plate is curved and projected, at a position corresponding to the front foot part, toward a ground.
- the hard plate can easily follow the shoe body when pushing off, and a separation (a distance) between the hard plate and the heel part of the shoe body is shortened, so that inertia moment of the shoe can be made smaller, and fatigue and burden of the foot can be reduced.
- a sectional shape of the hard plate in a width direction is formed into a corrugated shape.
- a weight of the hard plate can be reduced, and a strength of the hard plate in the length direction can be increased, so that performance of the hard plate can be kept for a long period.
- a bending resistance of a part of the hard plate corresponding to the area of the front foot part is smaller than that of another part corresponding to an area from an intermediate foot part to the heel part.
- the hard plate and the cushion material are backwardly projected from the shoe body.
- dispersion and reduction of grounding impact can be accelerated.
- an area of a ground contact side of the hard plate, in which the cushion materials can be provided can be broadened, so that options of attachment positions of the cushion materials can be increased, and the cushion materials can be optionally provided.
- the hard plate is provided on the bottom side of the shoe body, so that the cushion materials can be partially provided on the ground contact side of the hard plate without sacrificing comfort to wear.
- the hard plate is fixed to the bottom side of the shoe body only at the necessary location of the front foot part, so that the heel part of the shoe body (a rear foot part) separates from the hard plate when pushing off and flexibility of the shoe body can be maintained.
- the cushion materials are attached to the both end parts (the heel part and the toe part or the front foot part) of the ground contact side of the hard plate in the length direction, so that the cushion material need not be provided to the intermediate foot part and the weight of the shoe can be reduced.
- an amount of deformation of the cushion materials can be increased, and cushioning properties and the repulsion force can be improved.
- grounding impact while running can be absorbed by the cushion materials of the heel part and the front foot part, and the cushion material of the heel part restores by weight shift, so that the cushion material upwardly lifts a user wearing the shoes and the cushion material of the front foot part is further compressed. Therefore, the hard plate and the shoe body are inclined forward, and restoring the shoe can be accelerated.
- the cushion material of the front foot part which has been compressed when pushing off, restores, so that the user wearing the shoes is upwardly lifted and the thrust force is generated. Therefore, the cushion materials are deformed when grounding, so that the stored energy can be efficiently converted into the thrust force occurring upon push off.
- the structure of the shoe can be simplified, so that the light shoe can be mass-produced.
- a shoe 10 of the present embodiment comprises: a shoe body 1 into which a foot F is inserted; a hard plate 2 covering a necessary area on a bottom side of the shoe body in a length direction; and cushion materials 3 being attached on a ground contact side of the hard plate 2.
- the hard plates 2 entirely covers a bottom side of the shoe body 1 in a length direction.
- a suitable material of the hard plate 2 is a light and has high mechanical strength.
- the hard plate 2 is composed of carbon fiber resin, but the material of the hard plate 2 is not limited to the carbon fiber resin.
- the hard plate 2 is curved and projected, at a position of a front foot part, toward a ground when seen from a side.
- the hard plate 2 is fixed to a bottom side of the shoe body 1 only in a necessary length area including a border part between a phalange and a metatarsal (a necessary location of the front foot part). Namely, the hard plate 2 is not fixed to the bottom side of the shoe body 1 in an area from an intermediate foot part to a heel part (a rear foot part), and the hard plate 2 is capable of moving to and away from a bottom surface of the shoe body 1.
- Fig. 2 is a perspective view of the hard plate 2 seen from a lower side.
- a plurality of projecting stripes 2a are arranged, in a width direction of the hard plate 2, with prescribed separations.
- Recessed stripes 2b are respectively formed between the projecting stripes 2a. Namely, in an upper surface of the hard plate 2, the projecting stripes 2a shown in Fig. 2 form the recessed stripes 2b, and the recessed stripes 2b in a bottom surface of the hard plate 2 form the projecting stripes 2a, so that a sectional shape of the hard plate 2 in the width direction is formed into a corrugated shape.
- a weight of the hard plate 2 can be reduced, and a strength (a bending strength) of the hard plate 2 in the length direction can be improved.
- a depth of the intermediate foot part and the heel part is deeper than that of the front foot part.
- a bending resistance (a bending strength) of the hard plate 2 in an area of the front foot part can be smaller than a bending resistance (a bending strength) thereof in an area from the intermediate foot part to the heel part.
- the upper and the bottom surfaces of the hard plate 2 may be formed flat.
- Cushion materials 3 are respectively attached to both end parts, i.e., the front foot part and the heel part, of a ground contact side (the bottom side) of the hard plate 2 in the length direction. Namely, as clearly shown in Fig. 1 , no cushion material 3 is attached to a part of the hard plate 2 corresponding to the intermediate foot part, so that the parts of the cushion materials 3 contact the ground but the part of the hard plate 2 corresponding to the intermediate foot part is separated from the ground in a state where the shoe 10 is merely put on the ground.
- the cushion materials 3 are respectively attached to the locations of the ground contact side of the hard plate 2 corresponding to the front foot part and the heel part (at least the both end parts of the ground contact side of the hard plate 2 in the length direction).
- the cushion materials 3 are composed of a material having superior softness and elasticity, e.g., EVA (Ethylene-Vinyl Acetate). By partially providing the cushion materials 3 on the ground contact side of the hard plate 2, the shoe 10 can be suitably lightened.
- grounding impact can be efficiently stored in the cushion materials 3 as elastic energy (repulsion energy). Therefore, when the user pushes off the ground by a ground contact surface of the shoe 10, the repulsion energy generated by restoring the cushion materials 3 can be applied in a direction of push off as a thrust force, so that high power push off can be obtained.
- an area of attaching the hard plate 2 to the shoe body 1 and locations of attaching the cushion materials 3 are different from those of the shoe 10 of Embodiment 1.
- the hard plate 2 is provided to the bottom side of the shoe body 1 and in an area in the length direction from the front foot part to the heel part except a toe part. Namely, the hard plate 2 does not cover the toe part of the shoe 10.
- the hard plate 2 is attached to the bottom side of the shoe body 1 only in the necessary length area including the border part between the phalange and the metatarsal (the necessary location of the front foot part).
- the part not covered with the hard plate 2 is formed on the bottom side of the shoe body 1, a bending angle of a bending part of the shoe 10, which is a border part between the part covered with the hard plate 2 and the part not covered therewith, can be made wider.
- a bending angle of a bending part of the shoe 10 which is a border part between the part covered with the hard plate 2 and the part not covered therewith, can be made wider.
- the cushion material 3 is additionally provided to the bottom side of the shoe body 1 in the toe part which is not covered with the hard plate 2.
- the cushion material 3 provided to the toe part is separated from the cushion materials 3 which are attached to the both end parts of the ground contact side of the hard plate 2 in the length direction, and it is formed into a triangular shape when seen from a side.
- a maximum thickness of the cushion material 3 covering the toe part is approximately equal to that of the cushion materials 3 attached to the bottom side of the hard plate 2.
- the part of the shoe 10 not covered with the hard plate 2 is covered with the cushion material 3 of the front foot part.
- the cushion material 3 of the front foot part and the cushion material 3 of the toe part described in Embodiment 2 are integrated in the present embodiment. With this structure, in comparison with Embodiment 2, producing and attaching the cushion material 3 can be simplified, and durability can be improved.
- the hard plate 2 and the cushion material 3 attached to the heel part of the hard plate 2 are backwardly projected from a rear end of the shoe body 1 and form a projecting part 4.
- the projecting part 4 By forming the projecting part 4, impact absorbability when grounding can be improved, so that burden of the foot can be suitably reduced.
- the present invention has been explained in detail with reference to the embodiments, but the present invention is not limited to the embodiments.
- the shoe 10 of the above described embodiments is but the shoe may be suitably applied to a walking shoe.
- the cushion materials 3 act as ground contact members of the shoe 10, but outer sole members may be attached to the bottom surfaces of the cushion materials 3 as ground contact members.
- the bending resistance of the hard plate 2 in the length direction may be partially differed. Concretely, by employing the hard plate 2 in which the bending resistance in the area of the front foot part is smaller than that in the area from the intermediate foot part to the heel part, flexibility of the shoe 10 can be suitably secured even if the hard plate 2 is attached to the entire shoe body 1 in the length direction. Further, by attaching the hard plate 2 to the entire shoe body 1 in the length direction, the shoe 10 having stable comfort to wear can be produced.
- the cushion material 3 is attached to the toe part of the shoe body 1 (the part not covered with the hard plate 2), but the cushion material 3 attached to the toe part of the shoe body 1 may be omitted. With this structure, the weight of the shoe 10 can be further reduced. On the other hand, the cushion material 3 may be attached to cover the entire ground contact side of the hard plate 2. With this structure, stability of the shoe 10 can be improved and the hard plate 2 can be protected when running or walking on an uneven ground.
- Embodiments 1-3 may be selectively combined or applied to other examples.
