Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip sole with a non-slip formed on the sole of the sole.

[0002]

2. Description of the Related Art Conventionally, various devices have been devised as anti-skids on ice and snow, for example, those with increased frictional resistance of soles, those with metal spikes on soles, and those made of metal. There are spikes that appear and disappear as necessary.

[0003]

[Problems to be Solved by the Invention] However, when the frictional resistance of the sole is increased, a slipping effect can be expected on soft snow, but almost no slipping effect can be expected on hard ice and snow. With spikes made of steel, an excellent anti-slip effect can be expected on ice and snow.However, on ordinary roads, tiles, and PVC floors, not only is it slippery, but it also has the disadvantage of damaging the floor. In addition, if the metal spikes are made to appear and disappear as necessary, not only the structure is complicated and the production cost is increased, but also there are drawbacks such as complicated appearance and trouble, and it is necessary to solve these problems.

The present invention has an anti-slip effect on ice and snow below the freezing point and loses the anti-slip effect on a road surface or a floor surface at room temperature in a state in which wear is prevented, so that the anti-slip effect does not give a feeling of discomfort to ordinary walking. The purpose is to provide inexpensive shoe soles.

[0005]

The sole of the present invention is provided with a non-slip sole made of a soft material such as rubber, which is formed on at least the front tread of the front tread and the heel of the sole of the sole. A slipper made of a rubber compound having the property of hardening below freezing and softening at room temperature is provided on all or more of the front and rear recesses, with three or more pointed bodies protruding from the seat plate. The concave portion, which is formed by the molding or bonding means so that the tip of the body slightly projects from the back surface of the sole of the sole and does not form a slipper, is provided with decorative irregularities made of the same member as the sole of the sole. It is characterized by being formed integrally with the main body.

[0006]

The apex body integrally formed in the concave portion of the anti-slip shoe sole of the present invention configured as described above hardens below freezing and softens at room temperature above freezing. Ice and snow clog in the recessed part with the apex, and the apical body cools and hardens, so the tip of the slightly protruding apex bites into the ice and snow, and the shoe sole is bent by walking When the apex is projected, the amount of protrusion of the apical body increases, so that it can penetrate ice and snow more effectively, exhibiting an excellent anti-slip effect.When walking on general roads and floors, contact friction Since the sole of the shoe becomes below freezing due to the heat generated by the heat, the tip point softens and deforms due to the load due to the body weight, thereby losing the slipping effect and acting so that walking can be performed without discomfort.

FIG. 6 is a cross-sectional view taken along the line B, in which six concave portions 3 and a heel portion are formed in the front tread portion 2 on the back surface of the sole sole 1 made of vulcanized molded rubber that is not hardened below freezing and is based on butyl, SBR, or the like. 4, four concave portions 3 are formed, and three of the concave portions formed in the front tread portion and two of the heel portions 4 are hardened below freezing and softened at room temperature. A non-slip body 7 made of a rubber compound and having a protruding six-pointed triangular pyramid 6 on a seat plate 5 is provided.
The other concave portion 3 which is formed by molding or bonding means so as to protrude only weakly and does not form the non-slip body 7 is provided with a decorative uneven body having the same shape as the non-slip body integrally formed with the sole sole body 1. 9 is formed.

In the above, as the rubber compound having the property of hardening below freezing and softening at room temperature, conventionally known rubber compounds such as natural rubber and isoprene rubber,
A material obtained by adding a styrene resin to a butyl rubber in an increased amount, or a material obtained by adding an increased amount of a synthetic resin compatible with a rubber such as a vinyl chloride, an acrylic resin, or a urethane resin to an acrylic rubber or a nitrile rubber is used.

[0009]

As described above, the non-slip sole of the present invention is formed at least on the front tread portion of the front tread portion and the heel portion of the sole of the sole sole formed of a soft member such as rubber. A non-slip body made of a rubber compound having a property of hardening below freezing and softening at room temperature is provided on all or a plurality of the six or more recessed parts, and three or more pointed bodies are protruded from a seat plate. The tip of the cusp is integrally formed by molding or bonding means so as to slightly protrude from the back surface of the sole sole, and the concave and convex portions which do not form a slipper are provided with decorative irregularities made of the same member as the sole sole. Since it is formed integrally with the bottom main body, the apex body integrally formed in the recessed part hardens below freezing, softens at room temperature above freezing, and has an apex on ice and snow below freezing. The ice and snow clogged the area, causing the apical body to cool and harden, When the tip of the tip of the tip is cut into ice and snow, and when the shoe sole is bent by walking, the amount of projection of the tip is increased and the tip of the tip is deeper into the ice and snow, and an excellent slipping effect is exhibited. When walking on general roads or floors, the heat generated by contact friction causes the shoe sole to be below freezing, so the tiptoe softens and deforms due to the weight of the body, causing a slipping effect. Is eliminated, and walking without a sense of incongruity can be performed. In addition, since the pointed body is integrated with the concave portion formed mainly in the sole of the shoe by a molding means or an adhesive means, manufacture is simple.

Therefore, according to the present invention, there is an anti-slip effect on ice and snow below the freezing point, and the anti-slip effect disappears on a road surface or a floor surface at room temperature in a state where wear is prevented, thereby giving an uncomfortable feeling to ordinary walking. Non-slip soles can be provided at low cost.
