Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe with a spike, and more particularly to a shoe capable of preventing mud from firmly adhering to a shoe sole.

[0002]

2. Description of the Related Art For example, when playing rugby or baseball, it is common to wear shoes with spikes on the soles so that the feet do not slip due to rain on the ground due to rain during play.

[0003] However, if mud adheres to and remains around the spikes on the sole of the shoe, the mud adheres to the adhering mud one after another, and the lump of mud is firmly adhered to the sole of the shoe, resulting in smoothness. In such a case, it was necessary to hit or rub the sole of the shoe with an appropriate device to remove mud, which was very complicated.

On the other hand, a method is disclosed in which a spike is rotatably mounted on a shoe sole, and the attached mud is spontaneously dropped by rotation of the spike (Japanese Patent Laid-Open No. 2000-1395). A method in which a single piece of wool is provided and the attached mud is dropped by an elastic restoring force.
No. 5, JP-A-61-75702).

[0005]

However, in the method using a rotary spike, the structure of the spike is more complicated than that of a normal spike, and the process of manufacturing such a spike and setting it on a shoe sole becomes complicated. This leads to higher costs.

Further, the method using the elastic restoring force requires an operation of fixing the elastic body to the shoe sole, and requires a large change in the manufacturing process, which also increases the cost.

[0007] In view of the above problems, it is an object of the present invention to provide a shoe with spikes capable of preventing mud from firmly adhering to the sole of the shoe without increasing the cost.

[0008]

SUMMARY OF THE INVENTION Accordingly, a shoe with a spike according to the present invention is a shoe in which a plurality of spikes are provided on the sole of the shoe, and at least the entire surface between the plurality of spikes is provided on the bottom surface of the shoe sole. A minute concave portion or a minute convex portion is formed, and the minute concave portion or the minute convex portion is set to a shape and / or a size capable of retaining water in the minute concave portion or between the minute convex portions.

One of the features of the present invention is that the bottom surface of the shoe sole
At least a small concave portion or a small convex portion is formed on almost the entire surface between the spikes, and water is held in the small concave portion or between the small convex portions.

As a result, a water film is formed on the sole of the shoe, and when mud tries to adhere to the sole of the shoe between spikes, the mud is softened by contact with the water film and easily falls from the sole of the shoe. Moreover, since the mud does not contact the flat shoe sole but comes into contact with the minute unevenness, the contact area is small, and air is easily trapped between the mud and the bottom of the minute unevenness. Difficult to adhere to shoe soles. As a result, the mass of mud does not firmly adhere to the sole of the shoe.

Further, since minute irregularities are formed on the sole of the shoe, it is sufficient to process the mold, and the manufacturing process is not complicated, and the cost is not increased. That is, it is preferable that the shoe sole is manufactured by molding using a synthetic resin material, and the minute concave portion or the minute convex portion is formed at the same time when the shoe sole is manufactured by processing the mold surface of the forming die.

In order to surely prevent the mud from adhering, it is preferable to form minute irregularities on the spikes. That is, at the surface of the spike, at least a portion facing the shoe bottom where the minute concave portion or the minute convex portion is formed, a minute concave portion or a minute convex portion is formed, and the minute concave portion or the minute convex portion is in the minute concave portion or the minute convex portion. It is desirable that the shape and / or size be set so as to hold water therebetween.

The spike may be formed integrally with the sole, or may be detachably attached to the sole. In particular, when the spike is formed integrally with the shoe sole, fine irregularities may be processed in the spike portion of the mold, and there is no risk of complicating the manufacturing process.

The shape and size of the minute concave portion and the minute convex portion are not particularly limited as long as they can hold water, but it is preferable to adopt a shape having a small contact area with mud, for example, a triangular cross section or a trapezoidal cross section.

The present invention is applicable not only to rugby shoes and baseball shoes, but also to soccer shoes, golf shoes, and other spiked shoes.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to specific examples. 1 to 3 show a preferred embodiment of a shoe with spikes according to the present invention, which is an example applied to sports shoes. The shoe sole 10 is manufactured using a synthetic resin material, and the shoe sole 10 is integrally formed with seven synthetic resin spikes 11... On the toe side and four heel sides.

The bottom of the shoe sole 17 has a spike 11.
A plurality of minute concave portions 20 are continuously formed in a region surrounded by..., And the minute concave portions 20 are, for example, as shown in FIG. The depth is set to be approximately 1 mm to 2 mm and a substantially inverted cross section.

A plurality of minute recesses 20 are continuously formed on the surface of the spikes 11 at the portion facing the formation region of the minute recesses 20.
Numeral 1 is a substantially square plane having a length of 2 mm to 5 mm and a substantially inverted triangle having a depth of about 1 mm to 2 mm.

The above minute recesses 20,..., 21.
A three-dimensional micro convex portion complementary to the above is processed and formed at the same time when the shoe sole 10 is formed.

In the case of playing rugby, for example, by wearing the sports shoes of the present embodiment, if the shoes are stepped on a puddle or a weak place of the ground, the water will flow into the minute recesses 2 of the sole 10.
0, and as shown in FIG. 2, as shown in FIG.
Water films 30 are formed in 1.

When the player steps on a soft part of the ground with the shoes, the mud 40 tries to adhere to the shoe sole 10, but when the mud 40 contacts the shoe sole 10, the mud 40 comes into contact with the water film 30 and softens. The mud 40 tends to fall off the sole 10.

At the same time, the mud 40 does not come into contact with the flat shoe sole, but comes into contact with the sharp top edges of the minute recesses 20,..., 21. , And the bottom surfaces of the minute recesses 20..., 21.

As a result, the mud 40 does not adhere to the shoe sole 10 during the play, and even if it adheres, the mud 40 easily falls due to an impact during the play and the like, and the mud mass is firmly adhered to the shoe sole 10. I will not.

FIGS. 4 and 5 show a second embodiment. In the present example, a plurality of minute projections 25 are continuously formed in a region surrounded by the spikes 11 on the bottom surface of the shoe sole 10, and the minute projections 25 are, for example, as shown in FIG. And a trapezoid having a height of approximately 1 mm to 2 mm and a thickness of 2 mm to 3 mm.

As described above, instead of the minute concave portion 20, the minute convex portion 25 may be formed, or the minute convex portion 25 may be formed only in a predetermined region of the shoe sole 10, and further, optionally. It can also be formed in a shape and size.
