【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In describing this embodiment, a sports shoe will be taken as an example.

As shown in FIG. 1, the sports shoe 10 is composed of a cover 20 and a shoe sole 11, and the shoe sole 11 is formed by a midsole 30, a midsole 40 and an outsole 50. The insole 70 is put on the surface of the insole 30 in a stacked manner.

The cover 20 is formed of woven cloth, knitted cloth, natural leather, synthetic leather, or the like, and the insole 30 is formed of woven cloth / sponge / hard board or the like. In this example, a hard board (made by Tokushu Paper Co., Ltd.) was used as the insole 30. Further, the outsole 50 is formed of a material having high flexibility and elasticity such as vinyl chloride resin composition, polyurethane, thermoplastic rubber, styrene-butadiene rubber, isoprene rubber, butadiene rubber.

The midsole 40 attached to the upper surface of the outsole 50 with an adhesive is an expanded ethylene-vinyl acetate copolymer (EVA), expanded polyurethane, expanded vinyl chloride in order to absorb impact and reduce weight. It is formed of a system resin or the like. Further, a fitting hole 42 having a circular cross section for mounting the shock absorbing member 60 is formed through the center of the heel portion 41.

As shown in FIG. 2, the shock absorbing member 60 is formed by combining a lower cylinder 61 and an upper cylinder 65, and the lower cylinder 61 has a cylindrical portion 64 fitted in the fitting hole 42 as a bottom plate. A flange 63 is formed on the upper surface of the upper cylinder 62 and is raised. On the other hand, the upper cylinder 65 has a cylindrical portion 68 which is inserted into the cylindrical portion 64 and slides closely on the upper plate 66. It is a thing. For these materials, hard vinyl chloride resin, polyester, polyamide, hard polyurethane, polyethylene, polypropylene, etc. are used. The space 69 in the assembled cylinder may be air at normal pressure, but a coil spring, foam material, or other gas body is enclosed in a pressurized state to further increase the cushioning force and the restoring force. It may be in a bag.

The sports shoe 10 of this embodiment is of a hand-adhesive type, and is assembled by the following steps. First, the cover 20 is covered with a last not shown, and the lower edge 21 is hung on the lower surface of the insole 30 and bonded to form a shoe mold. Next, the shock absorbing member 60 is mounted in the fitting hole 42 of the midsole 40 so as to be sandwiched by the flanges 63 and 67 from above and below. That is, in the shock absorbing member 60, the flange 63 is fitted into the lower flange accommodating recess 43 formed in the lower portion of the fitting hole 42 of the midsole 40, the cylindrical portion 64 is fitted into the fitting hole 42, and the lower cylinder 61 is attached. Further, the flange 67 is fitted in the upper flange accommodating recess 44 formed in the upper part of the fitting hole 42, and is slidably slidably inserted into the cylindrical portion 64 so as to be mounted in combination. Therefore, the midsole 40 provided with the shock absorbing member 60 is attached to the upper surface of the outsole 50 by using an adhesive, and the shoe-shaped cloak 20 is also attached in the same manner as a sport as a shock absorbing shoe. Finish shoes 10.

With the above-mentioned configuration, in this sports shoe 10, when the heel portion 41 is impacted when landing, the upper cylinder 65 is pushed downward as shown in FIG. The midsole 40 is compressed by 67 and the space 69 in the cylinder is also contracted, so that the internal pressure rises and the shock is absorbed. At this time, since the impact absorbing member 60 is made of a hard material and is sandwiched by the flanges 63 and 67, the midsole 40 is not biased and there is no fear of impairing stability. When the impact disappears, the elasticity of the midsole 40 and the internal pressure of the pressure-increased space cause the midsole 40 and the impact absorbing member 60 to quickly return to their original shape.

Although the shock absorbing shoes of the embodiment of the present invention have been described above, the present invention is not limited to this embodiment, and the present invention is not limited to this embodiment, and the present invention can be made even if the configuration and the operation are changed without departing from the scope. Included in the device.

That is, although the shock absorbing shoe of this embodiment is of a hand-adhesive type, the shock absorbing member of the present invention can be applied to a shoe manufactured by injection molding or injection molding. Further, the shock absorbing shoe of the present invention can be used for business shoes other than sports shoes and casual shoes. Further, in the embodiment, the shoe sole is composed of the midsole and the outsole, but it is also possible to provide an upper sole on the midsole or to make the midsole have a multi-layered structure of two or more layers. . Further, in the embodiment, the midsole 40 is provided with the lower flange accommodating recess 43 and the upper flange accommodating recess 44, but if the flanges 63 and 67 are thin, such a flange accommodating recess is not required. Good.

[Effect of device]

 As described above, the present invention provides the shock absorbing shoe in which the shock absorbing member made of the hard material is attached to the insertion hole formed at the center of the heel of the elastic midsole. Due to the increase in internal pressure in the inner space of the cylinder and the elasticity of the midsole against the impact, the midsole is absorbed without being biased and the load on the leg joints is reduced. Further, when the impact disappears, the internal pressure is rapidly restored to the original state due to the increased internal pressure and elasticity, so that the stability is excellent and the restoring property is excellent. Also, since the fitting hole is made large and the space is also large, it is possible to maintain the lightweight property as well as conventional, and since it is sufficient to create and fit the shock absorbing member separately, the structure and processing method of the shoe itself etc. Can be simplified and the cost can be reduced.
