Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in the sole structure of baseball spike shoes.

[Conventional technology]

As shown in Figure 4, the conventional sole structure of this type of spike shoes has six grip points a on the sole g made of polyurethane material.
~f has a structure in which three biting metal fittings are attached with screws, bolts, etc.

[The problem that the idea aims to solve]

By the way, FIG. 5A is a map of equal pressure distribution on the feet of a professional baseball pitcher, and FIG. 5B is a map of equal pressure distribution on the feet of an infielder.

In the case of the pitcher A, pressure is also applied to the hallucis muscles as he needs to hold his foot when pitching, while in the case of the infielder B, greater pressure is distributed on the ballus hallucis muscles than on the ballus hallucis muscles.

The pressure distribution on the feet of ordinary baseball players also has a common feature, and it is possible to see where pressure is applied on the sole during running and landing.

However, with the sole structure of the spike shoes of the above-mentioned conventional technology, strong pressure is applied when running and landing, and the part of the hallucis muscle between the forefoot and midfoot that does not bend at that time becomes a flat surface. Because of this, there is less contact area with the ground during darts. Therefore, there is a problem that the balance during darts becomes poor.

Another problem with soles made of polyurethane is that when the user steps on the ground, the reaction force exerted from below increases.

Furthermore, there is a problem in that the arch portion of the sole breaks when running or landing.

Therefore, the object of the present invention is to provide a sole structure for baseball spike shoes devised in view of the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, in the sole structure of the baseball spike shoe according to the present invention,
In the sole of an athletic shoe with anti-slip on the contact surface side, each part of the forefoot, midfoot and rearfoot is interposed with a lightweight thermoplastic auxiliary member that has higher hardness and rubber elasticity than the material of the sole. In addition, a metal fitting is installed in the forefoot and midfoot area near the hallucis muscle, which is subject to pressure when running and landing, to ensure smooth landing motion, kicking action, sliding and landing, and prevent wear and tear. The shoe is characterized by having a convex portion parallel to the sole surface arranged in an inward arc to prevent the problem, and a bent member having a plurality of concave portions provided in the arch portion.

[Effect]

After fixing auxiliary members with a shape slightly larger than the fittings to the attachment parts of the forefoot, midfoot, and rear foot parts of the sole using fixing means such as welding, attach the biting fittings of each part to screws or bolts. Attach with etc.

In addition, the stop/dutch mechanism has a bending member attached to the bottom surface of the sole by welding or other fixing means to the forefoot and midfoot areas, where strong pressure is applied during darts, for example, near the hallucis muscle. Attach to.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained below based on the drawings.

In FIGS. 1 to 3, a sole 1 is used for baseball spike shoes made of polyurethane material, and the sole 1 includes a shoe that cuts into six grip points of the spike shoe. Biting fittings 2, 21, 2 having parts 23, 24, 25
2 is placed.

Of these, a biting fitting 2 is attached to the forefoot portion 4, a biting fitting 21 is attached to the midfoot portion 5, a biting fitting (grip fitting) 22 is attached to the rear foot portion (heel portion) 6, and the following auxiliary support is provided. They are arranged with members 7, 71, and 72 interposed therebetween.

Further, the auxiliary members 7, 71, 72 of the respective attachment parts of the respective biting fittings 2, 21, 22 are made of a lightweight thermoplastic resin that is harder than the material of the sole 1 and has rubber elasticity. 7, 71, 72 are
It is fixed to the bottom surface of the sole 1 by fixing means such as welding.

Note that the auxiliary members 7, 71, 72 are preferably formed into a larger shape than the external shape of the biting metal fittings 2, 21, 22.

In addition to the above conditions, the auxiliary members 7, 71, and 72 should preferably have low-temperature properties, high elastic recovery rate, and excellent bending resistance, fatigue resistance, chemical resistance, and the like.

The biting fittings 2, 21, 22 are fastened with screws 31 or bolts 3 with the auxiliary members 7, 71, 72 interposed therebetween.

Further, on the back surface of the sole 1, the forefoot section 4 is provided with the auxiliary members 7, 71,
A stop/dash mechanism 8 is provided which is made of the same material as 72 and has a larger contact area with the ground surface.

This stop/dash mechanism 8 has a base 81
As shown in Fig. 3, an inclined surface 82 of a certain angle (60 to 70 degrees) is formed in the forward direction of running to ensure smooth landing motion, and the rear surface 83 is inclined at approximately 90° to facilitate the kicking action. ° and the top 84
consists of a plurality of protrusions 85 formed parallel to the sole surface in order to smooth sliding and landing and prevent wear.The protrusions 85 are larger on the outside than on the inside of the foot, and the entire surface of the foot is It is best to place it inward in such a way that it draws an arc toward the inside of the room.

Furthermore, a bent member 9 made of the same material as the auxiliary members 7, 71, 72 is provided in the arch portion 9.
1 is arranged, and this bending member 91 is provided with several recesses 92 so that it can be elastically and smoothly bent at the arch portion 9.

Similar to the convex part 85, this concave part 92 is arranged so as to draw an inward arc on the inside of the foot.
is provided in such a manner that the outside is larger than the inside, and is fixed to the bottom surface of the base 1 by a predetermined fixing means such as welding.

Further, the base 81, the auxiliary member 71, and the bending member 91 of the stop/dash mechanism 8 may be formed integrally as shown in FIG.

[Effect of idea]

Since the present invention is configured as described above, it produces the following effects.

A: In addition to providing bite-sized metal fittings on each part of the forefoot, midfoot, and rear foot (heel), there is a sloped part in the forward direction of running in the area that receives strong pressure when landing, and a sloped part in the rear part.
A stop/douche mechanism with a convex part with a flat top at an angle of about 90° is provided, and an elastic bending member is provided in the arch of the foot, allowing for smooth landing, running, and sliding during darts. Operation becomes possible.

B In addition, the forefoot, midfoot, and rearfoot (heel) bits are attached to the bottom of the sole with auxiliary members interposed, so they can be pushed from below when stepping on the ground. The resulting reaction force is alleviated, and the elasticity is good, so there is less strain on the feet.

C. By providing a concave bending member in the arch of the foot for reinforcement, accidents such as the arch of the sole breaking can be prevented regardless of whether the ground is hard or soft.

D The materials used for the auxiliary members, bending members, and stop/dash mechanism are lightweight and have high durability, making it possible to reduce the weight of the sole.
