Description

  The present invention relates to an athletic shoe suitable for jogging, training, and the like, and further, an athletic shoe having a sole formed by interposing a resin plate having a cylindrical cushion between a midsole and an outsole of a soft elastic body. It is about.

  As a conventional athletic shoe, a shoe sole having a midsole and an outsole formed on the lower surface thereof is generally used. The midsole is generally composed of a soft elastic body in order to ensure cushioning properties. For this reason, the heel portion of the shoe sole is fatigued by the impact force at the time of landing, tends to sag during a long period of time, and the cushioning property tends to be lowered.

  Furthermore, athletic shoes are required to have running stability in addition to cushioning properties. That is, it is necessary to prevent the athletic shoes from deforming excessively in the left-right direction at the time of landing and causing a so-called lateral shift.

Therefore, in the midsole structure of sports shoes, a corrugated sheet is interposed in the heel portion in the midsole composed of a soft elastic member, and a plurality of through holes are formed at locations where the midsole contacts the corrugated sheet. This is proposed in Japanese Patent Laid-Open No. 11-346803. In this proposal, the corrugated portion of the corrugated sheet can prevent the heel portion of the midsole from being laterally displaced in the left-right direction, and the running stability of the shoes is ensured. However, since the corrugated sheet is not directly supported by the outsole by inserting the corrugated sheet into the midsole in this way, the heel portion of the midsole is also deformed in the left-right direction and the vertical direction and becomes unstable. There is a tendency. For this reason, even if it is a site | part which requires driving | running | working stability in the heel part of a midsole, the stability at the time of landing fell and was not satisfactory.

  The problem to be solved is to solve the disadvantages of the conventional products, ensure the running stability of the shoes, prevent the midsole made of soft elastic members from sagging, extremely light weight and good cushioning An athletic shoe having a sole is provided.

  The present invention provides an athletic shoe having a cover and a shoe sole, wherein the shoe sole is fitted to the transverse groove in a midsole in which a suitable number of transverse grooves are formed on both sides of the lower surface of the heel portion, and A gist is an athletic shoe characterized in that a resin plate having a cylindrical shock absorber opening on the side surface of the shoe sole is provided and an outsole is joined to the lower surface of the resin plate. In addition, the resin plate has a shape in which the tip thereof extends to the front of the shoe sole depression portion.

  The shoe sole of the athletic shoe according to the present invention includes a resin sheet provided with a cylindrical cushioning body formed in a suitable number of lateral grooves on the lower side of the heel of the midsole and embedded in the lateral grooves. Since the cylindrical buffer body is embedded in the midsole by joining the outsole to the lower surface of the resin plate, the lateral deformation is caused by the resin sheet with the cylindrical buffer body. And the running stability of the athletic shoes can be secured. Moreover, since the athletic shoe of the present invention has a through-hole in the lateral direction formed in the cylindrical shock absorber, it is lightweight and can reduce the impact force applied to the buttocks during running and improve the cushioning property. . Moreover, since the cylindrical shock absorber fitted to the midsole is directly joined to the outsole, the impact force and repulsive force applied to the heel can be directly supported by the outsole, so that a good cushioning property is maintained for a long time. Further, there is an advantage that the midsole is prevented from being sag. And since the said resin plate consists of the shape which extended the front-end | tip to the shoe sole non-stepping part front, further running stability can be ensured.

  The purpose of ensuring the running stability of the athletic shoes was realized by interposing a resin sheet provided with a cylindrical buffer between the midsole and the outsole.

  FIG. 1 is a side view of an athletic shoe of the present invention, and FIG. 2 is a bottom view of the athletic shoe of FIG. 3 is a cross-sectional view of the athletic shoe of FIG. 1 taken along the line AA. In the figure, 1 is an athletic shoe, 2 is a cover, 3 is a shoe sole, 4 is a midsole, 5 is a resin plate provided with a cylindrical buffer portion 5a, and 6 is an outsole.

  An athletic shoe 1 according to an embodiment of the present invention includes a hood 2 and a shoe sole 3 provided on the bottom surface thereof. In addition, the shoe sole 3 includes a midsole 4, a resin sheet 5 including cylindrical buffer bodies 5 a and 5 a, and an outsole 6. The midsole 4 is used for the purpose of relaxing the impact force applied to the buttocks. The midsole 4 is formed with two rows of concave grooves 4a, 4a spaced apart on both sides of the lower surface of the buttock. The resin plate 5 is provided with cylindrical buffer bodies 5a and 5a that fit into the lateral grooves 4a and 4a on the upper surface of the resin plate body, and is joined to the lower surface of the midsole 4 with an adhesive. Further, the outsole 6 is bonded to the bottom surface of the resin plate 5 with an adhesive to complete the athletic shoe.

  The material forming the midsole 4 is a soft elastic material having cushioning properties, and specifically, an ethylene-vinyl acetate foam, a polyurethane foam, or the like is used.

  The resin plate 5 is made of a thermoplastic resin such as polyvinyl chloride or ABS resin, and the resin plate main body and the cylindrical buffer bodies 5a and 5a may be integrally formed by injection molding, or constituent parts may be separately formed. It is also possible to create and assemble and join these parts. The cylindrical shock absorber 5a may have a cross-sectional shape that is the same as that of the grooves 4a and 4a of the midsole, and may be any of a square shape, a trapezoidal shape, and a semicircular shape. The cylindrical shock absorber 5a according to the embodiment of the present invention has a shape with a square cross section. As a result, the midsole 4 supports the impact force at the heel portion from the cylindrical buffer bodies 5a and 5a on both the left and right sides, and is softened at the thick central portion. Further, the resin plate 5 may be provided with a shank function by extending the front end of the resin plate 5 to the front of the shoe sole non-pressing portion and integrally forming the shank 5b.

  The outsole 6 is made of a tough elastic material, and is specifically formed of natural rubber, synthetic rubber or the like.

  The athletic shoe 1 of the embodiment is provided with the cylindrical shock absorbers 5a, 5a of the resin plate 5 embedded in the left and right sides of the lower surface of the heel part of the midsole 4, so that the impact force applied to the heel part is softened, Since it is supported by the resin plate 5 provided with the cylindrical shock absorbers 5a and 5a, the running stability of the athletic shoes can be ensured, and the weight of the athletic shoes can be prevented and the midsole can be prevented from sag. Moreover, the midsole is formed with a thicker central part than the left and right sides, so that the cushioning property is good.

  Since the athletic shoe 1 of the present invention uses the shank 5b that is integrally formed by extending the front end of the resin plate 5 to the front of the shoe sole depression, it has a shank function and can further ensure running stability.

It is the side view which looked at the athletic shoes of the Example of this invention from the side. FIG. 2 is a bottom view of the athletic shoe of FIG. 1 viewed from the bottom. It is sectional drawing of the state which cut | disconnected AA of the athletic shoes of FIG.
