Description

[Detailed description of the invention] The present invention is an athletic shoe, more specifically, a protrusion called a spike, stud, point, cleat, etc. is placed on the back side of the shoe sole of an athletic shoe, especially a baseball shoe. Concerning structural improvements.

(Background Art) In general, protrusions called spikes, studs, points, cleats, etc. are provided on the side of the sole of athletic shoes to prevent slipping, etc., but in particular, in the case of baseball shoes, protrusions called spikes, studs, points, cleats, etc. For example, because explosive power is especially required when running from the base position, or because it is necessary to fix the position of the pivot foot when a pitcher pitches, the protrusion provided on the back side of the sole of the shoe allows the projection to touch the ground to some extent. The condition is that it penetrates into the

Therefore, the protrusions provided on baseball shoes have conventionally been mainly made of metal with relatively sharp tips (generally called spikes), but because they are made of metal, they can be used on bases, for example. This had a serious drawback in that it was extremely dangerous when a cross play occurred, and defenders could be injured by the runner's spikes. Considering the current situation in which the number of baseball players who use shoes with spikes is overwhelmingly higher among amateur players such as Murokusa Baseball than among professionals such as professional baseball, the above-mentioned drawbacks become a serious problem. It was.

In order to overcome this drawback, attempts have been made to provide non-metallic protrusions made of synthetic resin or the like called studs integrally on the back of the sole, but in this case, the studs may wear out. This is extremely severe, and because the studs are integrally provided on the back of the shoe sole, the wear of the studs can cause damage even though there is no damage to any part of the shoes other than the sole, such as the upper. There is a drawback that the function as a baseball shoe is lost in a short period of time,
On the contrary, the problem was that it was uneconomical and difficult to put into practical use.

(Problem to be solved, technical objective) The present invention aims to solve all of the above-mentioned drawbacks, and in particular, in order to ensure safety, instead of using metal protrusions called spikes, it is necessary to use non-metallic protrusions called studs. It was devised primarily as an improvement to baseball shoes based on the premise of using the protrusions of the stud, and its purpose was to significantly reduce wear on the stud itself, allowing it to be used for a long time. The object of the present invention is to provide a completely new and useful shoe for exercise.

(Disclosure of the invention) The present invention was constructed to achieve the above-mentioned object, and its structural features include a sole body and a wear-resistant material made of a separate member from the sole body. A protrusion is formed on one of the studs and a recess is formed on the other, and the protrusion or recess of the sole body is fitted into the recess or protrusion of the stud so as to cover the entire protrusion in the recess. The studs are molded at the same time as the sole body is molded.

That is, in the present invention, only the studs that come into direct contact with the ground are made of a wear-resistant material that is separate from the sole body, thereby preventing loss of functionality due to wear of the studs as athletic shoes.

(Effects) Since the present invention is an exercise shoe having the above-mentioned features, it has achieved the following remarkable effects.

(b) In other words, only the studs that come into direct contact with the ground are made of a wear-resistant material that is separate from the sole body, so the studs will never wear out in a short period of time, making it easier for the upper, etc. A remarkable effect is that the shoe can be used for a long period of time until parts other than the sole are damaged.

(b) Furthermore, the studs are attached to the sole body so that the protrusions and recesses are fitted and the entire protrusions are covered by the recesses, so that they are resistant to external forces, especially lateral forces in the front, rear, left, and right directions. Due to its extremely strong structure, the studs are almost completely prevented from coming off during shoe use, even though the studs are separate from the sole body before molding. effective.

(c) Furthermore, since the studs are attached to the sole body at the same time when the sole body is molded, the shape of the protrusion formed on either the stud or the sole body is also T-shaped. It can be formed into complex shapes that would be impossible to fit into the recess if molded separately from the main body.
As a result, various combinations of protrusions and recesses can be obtained which provide a structure that is extremely resistant to the force of the stud coming off, and this has the special advantage of more reliably preventing the stud from coming off the sole body. There is.

(Embodiment) The embodiment of the present invention will be described below according to an example shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes the sole body of a baseball shoe made of flexible urethane resin, and approximately rectangular parallelepiped-shaped protrusions 2 are located at four locations on the right and left of the relatively peripheral portion of the back side of the sole body 1. is installed protrudingly. Reference numeral 3 denotes a stud made of nylon whose bottom surface 4 has an elongated rectangular parallelepiped shape and which has a low degree of wear.
A recess 6 is formed into which the protrusion 2 can be fitted, and the protrusion 2 is fitted into the recess 6 to cover the entire protrusion 2. When the sole body 1 is molded, the sole body 1 is molded simultaneously. It becomes fixed. Incidentally, reference numeral 5 indicates an auxiliary stud that projects integrally with the sole body 1.

The sole 7 of the baseball shoes having the above-mentioned structure is manufactured by applying an adhesive or the like to the bottom surface 4 of the stud 3 in which the concave portion 6 is formed in advance and to the inner wall surface of the concave portion 6, and then molding it. (not shown), and then inject urethane resin into the mold and harden it to form the sole body 1. At the same time, the studs 3 are fixed to the sole body 1 via adhesive. It is manufactured by

In this case, the sole body 1 and the studs 3 can be firmly bonded together by using an adhesive, but it is also possible to bond the sole body 1 and the studs 3 together without using adhesive. .

When using a baseball shoe having the sole 7 constructed as described above, the studs 3 come into direct contact with the ground, but the studs 3 are separate members from the sole body 1 and have a low degree of wear. Since it is made of nylon, the stud 3 will never wear out in a short period of time and become unusable even if the shoe is used frequently.

Furthermore, the stud 3 is attached to the sole body 1 by fitting the protrusion 2 of the sole body 1 into the recess 6 of the stud 3 so as to cover the entire protrusion 2. The mounting has a very strong structure against external forces, especially lateral forces in the front, back, left, and right directions, and therefore, when using the above shoe, for example, even when the bases are running, large forces applied from the outside will not cause the stud to fail. 3 will not come off from the sole body 1.

Moreover, since the shape of the stud 3 is such that the bottom surface 4, which is the surface in contact with the ground, is in the shape of an elongated rectangular parallelepiped, the force of digging into the ground required for a baseball shoe is sufficiently guaranteed.

In the above embodiment, the sole body 1 has a protrusion 2.
The stud 3 is formed with a recess 6, but on the contrary, as shown in FIG. The stud 3 may be attached to the sole body 1 by fitting the stud 3' into the recess 6'.

Furthermore, the shape of the projection 2 is not limited to the rectangular parallelepiped shape of the embodiment, for example,
As shown in the figure, the studs may be formed to have a T-shaped cross section. In this case, the structure is particularly strong against the force of the studs coming off, and the studs 3 can be more reliably prevented from coming off from the sole body 1. There are advantages. If the protrusion 2 is formed into a complex T-shaped cross section as described above, the protrusion 2 will be formed into the recess 6 when the stud 3 and the sole body 1 are usually molded separately.
However, in the above embodiment, when the sole body 1 is molded, the stud 3 is molded at the same time as the projection 2 is fitted into the recess 6. Even if the projection 2 has a T-shaped cross section as described above, the projection 2 and the recess 6 can be fitted together.

In other words, since the stud 3 is attached at the same time as the sole body 1 is molded, the shape of the protrusion 2 is not limited to the above-mentioned T-shaped cross section, and it is thought that it would be impossible to fit into the recess 6 under normal circumstances. The stud 3 can be formed into a complicated shape, and as a result, a great effect is produced in that various combinations of protrusions and recesses can be obtained that can reliably prevent the stud 3 from coming off.

In this embodiment, the studs 3 are attached to the bottom surface 4.
The shape of the stud 3 is a long and narrow rectangular parallelepiped, which has the desired effect of not impairing the ability of the stud 3 to bite into the ground, but the shape of the stud 3 is by no means limited to this. Therefore, the present invention can be applied to shoes for sports other than baseball. What is important is that the stud has a recess 6 or protrusion 2' that can be fitted with the protrusion 2 or recess 6' formed on the sole body 1.

Furthermore, the material of the studs 3 is not limited to the nylon used in this embodiment, and may be made of, for example, a material made of glass fiber and nylon, or other materials such as polyethylene, Diuracon (trade name), polyacetate, etc. . In short, it only needs to be made of a wear-resistant material.

Furthermore, the material of the sole body 1 is by no means limited to the urethane resin used in this embodiment, but may be made of any material that easily fits the foot as a sole.

Further, in this embodiment, all of the four studs 3 on the back side of the sole body 1 are made of nylon that is separate from the sole body 1 and has a low degree of wear, but it is not necessary that all four studs 3 are It is not necessary to construct the sole body 1 from a wear-resistant material, and only the two studs 3 provided inside the sole body 1 may be constructed from a wear-resistant material. That is, in the baseball shoes of the above embodiment, the part that is subject to severe wear is mainly the studs on the inside of the sole body 1, so by making only the studs 3 on the inside of the sole body 1 from a wear-resistant material, at least the baseball shoes It functions well as a personal shoe.

Furthermore, the number of studs 3 is also 4 in this embodiment.
It is not limited to individuals.

All other design changes may be made within the scope of the present invention.
