Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole and, more particularly, to a non-slip sole used for shoes worn in places where road surfaces freeze, such as in cold regions.

[0002]

2. Description of the Related Art Conventionally, when walking on a frozen road surface, such as a sidewalk in a cold region, the foot soles of winter shoes and boots are variously used to walk on a frozen road surface without slipping. Some ingenuity has been made. For example, some shoe soles provided in conventional winter shoes and boots are provided with spike fittings and spike pins that bite into a frozen road surface at important points on the bottom surface of the shoe sole. In some cases, a contact pattern generated between a frozen road surface and a sole surface of a shoe is improved by forming a slip resistant block pattern or a spike-like projection on the bottom surface of the shoe sole.

[0003]

Among the above-mentioned conventional soles, those having a spike fitting or a spike pin at a required position on the bottom of the sole have a problem that the spike fitting or the spike pin bites into a frozen road surface. The anti-slip effect on the road surface is good. However, as mentioned above,
In the case where the spike fitting or the spike pin is embedded in the bottom surface of the shoe sole, the production is troublesome and the number of parts to be used increases, so that the production cost is inevitably increased. Further, those provided with spikes and spike fittings on the sole of the shoe have a high anti-slip effect on a frozen road surface, but have a drawback that they easily slip on a dry road surface. In the case of a block pattern or a spike-like projection that is resistant to slippage on the bottom surface of the shoe sole, although there is an anti-slip effect due to a large number of irregularities and grooves, these irregularities and grooves, sharp projections, etc. Is made of relatively soft rubber or vinyl chloride, so it has low adhesion to the frozen surface, and its anti-slip effect is provided by the spike metal fittings and spike pins on the bottom of the shoe sole as described above. It is inferior to the one.

The sole of the present invention has been made in view of the conventional circumstances as described above, and its object is to provide a sole for use in winter shoes, boots, and the like, and to increase spike fittings, spike pins, etc., which increase production costs. An object of the present invention is to provide a high anti-slipping function for a frozen road surface without using a vehicle.

[0005]

In order to solve the above-mentioned problems, a shoe sole according to the present invention has a mounting portion of a predetermined shape formed on a bottom surface of a sole body, and a rubber non-slip is provided on the mounting portion. A body is provided, and a cloth material is mixed in the rubber material of the non-slip body.

[0006] According to the above means, a rubber non-slip body is provided on the mounting portion provided on the bottom surface of the sole body.
As a result, the non-slip body is fixed to the bottom of the shoe sole,
Contact with frozen road surface when walking. The above shoe sole is
Although the cloth material is mixed inside the rubber material constituting the non-slip body, at the beginning of use, there are few portions exposed to the surface while remaining mixed inside the rubber material. However, by using the shoe provided with the sole several times, the rubber material covering the surface of the non-slip body is worn, and the cloth material mixed inside the non-slip body is exposed. The cloth material exposed from the surface of the above-mentioned non-slip body is not different from a normal shoe sole when walking on a dry road surface. However, when it comes into contact with a frozen road surface, the fibers of the cloth material adhere to the frozen road surface, and a strong adhesive force is generated between the shoe sole and the frozen road surface.

According to a second aspect of the present invention, a part of the cloth material mixed inside the non-slip body is exposed on the surface of the non-slip body. According to the above-described means, the cloth material is mixed in the rubber material constituting the non-slip body, and the cloth is exposed on the surface of the non-slip body from the beginning of use.
This cloth material does not exhibit particularly good adhesion when walking on a dry road surface, and does not differ from ordinary shoe soles. However, if the cloth material comes into contact with a frozen road surface,
The fibers of the cloth material instantly adhere to the frozen layer on the frozen road surface, and a strong adhesive force is generated between the shoe sole and the frozen road surface.

According to a third aspect of the present invention, the cloth material exposed on the surface of the non-slip body is buffed, and the exposed portion of the cloth material is raised. In this case, the cloth material exposed on the surface of the non-slip body is raised by buffing (the fibers are loosened and fluffy). As a result, the cloth material raised as described above efficiently adheres to the frozen road surface, and the adhesive force generated between the shoe sole and the frozen road surface is further increased.

According to a fourth aspect of the present invention, in the shoe sole, the non-slip body is integrally formed in a substantially zigzag shape, and is mounted on a mounting portion on the bottom surface of the sole body. As described above, the non-slip body attached to the bottom surface of the sole body is formed by integrally forming a plurality of non-slip bodies by connecting them in a zigzag shape, thereby disposing a plurality of non-slip bodies separately. Has substantially the same level of anti-slip function.

Next, the unvulcanized rubber b for forming the shoe sole a is packed into the cavity f 'of the above-mentioned mold f, and is packed on the forming portions f1 and f2 for forming the above-mentioned anti-slip bodies 1a and 1b ( (Fig. 6). Thereafter, the upper mold g is placed on the upper surface of the molding die f.

The molding die f and the upper die g are vulcanized at a predetermined temperature and pressure for a predetermined time. Further, when vulcanizing, the base cloth material c wound in a spiral shape as described above.
Adheres so as to be pressed against the lower surface of the mold in the molding portions f1 and f2, so that the non-slip bodies 1a and 1 after the molding are formed.
The base cloth material c (cloth material 3) is exposed on the surface of b. The molded portions f1 and f2 are formed so as to have a wide width and a lower surface thereof formed in a substantially mountain shape to increase an exposed area. Therefore, the surfaces of the formed non-slip bodies 1a and 1b are provided with: The above-mentioned base cloth material c (cloth material 3) is exposed over a wide range.

When the vulcanization is completed, the two molds f and g are separated from each other, and in the cavity f ', the shoe sole a having the non-slip bodies 1a and 1b integrally formed on the bottom surface is released, and the mold protrudes around the molded product. Remove the burr. Non-slip members 1a and 1b are integrally formed on the bottom surface a 'of the shoe sole a vulcanized and formed as described above. The surface of the non-slip members 1a and 1b is buffed to expose a wide range of the cloth material 3 mixed in the rubber material of the non-slip members 1a and 1b, and to raise the exposed cloth material 3 ( Fig. 7-a).

Further, the shoe sole of the present invention is obtained by vulcanizing the shoe sole a and the non-slip bodies 1a and 1b in the molding die as described above, and then buffing the surfaces of the non-slip bodies 1a and 1b. The cloth material 3 mixed in the rubber material was exposed and raised. However, according to the gist of the present invention, the step of buffing the surfaces of the non-slip bodies 1a and 1b after vulcanizing the shoe sole a may be omitted. In this case, start using the shoes with the non-slip body 1

As described above, the sole of the present invention is
A rubber non-slip body is provided on a mounting portion provided on the bottom surface of the shoe sole body, and a cloth material is mixed inside the rubber material of the anti-slip body. Therefore, the above shoe sole has a cloth material mixed inside the rubber material constituting the non-slip body. The rubber material covering the surface of the non-slip body is worn by using the shoe with the above sole several times, but the cloth material mixed inside the non-slip body Is gradually exposed, and is exposed to a wide area and is naturally raised. Therefore, when it comes into contact with a frozen road surface, as described above, the fibers of the cloth material exposed on the surface of the sliding body closely adhere to the frozen layer of the frozen road surface, and a strong adhesion force between the shoe sole and the frozen road surface. And exhibit a good anti-slip effect.

According to a second aspect of the present invention, the shoe sole is formed by exposing a part of the cloth material mixed inside the non-slip body to the surface of the non-slip body. According to the above means, the cloth material is mixed inside the rubber material constituting the non-slip body, and a part of the cloth material is exposed on the surface of the non-slip body from the start of use of the shoe. Therefore, when walking on a frozen road surface, the cloth material exposed on the surface of the non-slip body comes into contact with the frozen road surface.
At this time, the fibers of the cloth material instantaneously adhere to the frozen layer of the frozen road surface, and a strong adhesion force is generated between the shoe sole and the frozen road surface, and a good non-slip when walking on the frozen road surface. It is effective. Further, the cloth material exposed on the surface of the non-slip body is mixed as a plurality of layers at intervals in the rubber material constituting the non-slip body, so that even if the surface of the non-slip body is worn by use, Since the new cloth material is sequentially exposed from the inside of the rubber material, the non-slip bodies 1a, 1
