JPH08266304A - Antiskid shoe sole - Google Patents

Abstract

PURPOSE: To provide an antiskid shoe sole having the capability of giving an antiskid function outdoors in a snowy and cold area, and preventing damages to a floor indoors. CONSTITUTION: Many surrounding projection walls 2 are formed on a lower surface in contact with the ground, and a part of the walls 2 is cut out like grooves 3. A body section 4 including the walls 2 is formed out of polymeric elastic material having A-hardness between 40 and 60 degrees on the snow, by JIS K6301 spring type hardness tester.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip shoe sole which has anti-slip properties outdoors in snowy regions and which does not damage the floor surface indoors.

[0002]

2. Description of the Related Art Conventionally, as a shoe sole having slip resistance on snow,
Japanese Utility Model Publication No. 46-32432 is proposed. This shoe sole is provided with a cylindrical protrusion on the grounding surface, and a metal spike stud is projected in the center of the cylinder so that its tip is slightly lower than the tip of the cylindrical protrusion, and its base is embedded in the sole. Installed.

[0003]

The shoe sole described in the prior art has good anti-slip properties because the tip of the spike stud pierces a low-temperature walking surface such as walking, snow, or ice. When these shoe soles are used on a floor or road surface covered with boards, tiles, linoleum, PVC, etc. at room temperature,
There was a defect that the floor surface and the road surface were markedly damaged by the spike studs, and the design was covered with ice, snow, and dirt. The present invention is intended to provide a shoe sole having excellent floor and road surfaces at normal temperature and slippery wear feeling at low temperature.

[0004]

The present invention for solving the above-mentioned problems has a large number of surrounding projecting walls (2) on the lower surface (1), and the surrounding projecting walls (2) are partially The body portion (4), which is notched in the shape of the groove (3) and includes the surrounding wall (2), has a high A hardness of 40 to 60 degrees on snow according to JIS K6301 spring hardness tester. It is characterized by an anti-slip sole made of a molecular elastic material.

In carrying out the present invention, as the polymer elasticity, natural rubber, styrene-butadiene copolymer rubber, polyisoprene rubber, polybutadiene rubber and the like are compounded rubbers close to pure rubber, and compounded polyurethane using a large amount of a softening agent. , Ethylene vinyl acetate copolymer, polyvinyl chloride, etc. are used. The groove (3) of the surrounding projecting wall (2) is usually one place, but may be plural places. Such surrounding wall (2) may be provided on the entire surface of the lower surface (1) at a constant pitch, or may be provided as a group on the stepped part and the heel part or one of them.

Further, the grooves (3) of the adjacent surrounding wall (2) may be arranged in any direction, or four groups may be formed as a set, and the grooves (3) cut out in the grooves may be arranged in different directions in the front, rear, left and right directions. May be designed to be Furthermore, the surrounding wall (2) is circular,
Polygons (hexagons, triangles, squares, pentagons, etc.), squares, diamonds, rectangles, etc. are used as appropriate. Further, a conical small projection (5) may be provided between the surrounding projecting walls (2), and the surrounding projecting wall (2) has a cross-section tapered toward the ground contact surface. You can also

[0007]

In the anti-slip sole of the present invention, the surrounding projecting wall (2) provided on the lower surface (1) of the main body (4) has the above hardness on snow and has a sufficient elastic body. Therefore,
Even if the inside and outside thereof are covered with snow, the surrounding wall (2) bends inward or outward when it is stepped on, and pushes out the blocked snow. This effect is further promoted by the groove (3).

Further, this action is exerted by the groove (3) of the four surrounding projection walls (2) regardless of the direction of action. Further, if a conical small projection (5) is provided between the surrounding projecting walls (2), and further, the cross-sectional shape of the surrounding projecting wall (2) is tapered toward the ground contact surface, the effect of the invention. Is further promoted. Also, after walking on snow, indoors (or indoors)
Even if it goes in, the floor surface will not be damaged due to its elastic coefficient.

[Embodiment] The construction of an anti-slip shoe sole is shown for a typical embodiment of the present invention. FIG. 1 is a plan view of the shoe sole of the present invention.
FIG. 2 is an enlarged view of a main part of FIG. 1, and the outer shape of the surrounding projection wall (2) is inscribed in a diameter of 8 mm and an inner diameter of 6 mm. The cross-sectional shape is tapered toward the ground plane as shown in FIG. 3, which is a cross-sectional view taken along the line AA of FIG. Its height is 2 mm.

The surrounding projection walls (2) are arranged at a constant pitch on the entire lower surface (1) of the main body (4). A cutout groove (3) having a width of 1 mm is provided on one side of the hexagon of the surrounding projecting wall (2). As shown in FIG. 2, the notch groove (3) is formed in different directions in the front, rear, left and right, and a conical small protrusion (5) having a diameter of 2 mm and a height of 1.5 mm is provided between the surrounding projecting walls (2). ing. Such a sole is a soft rubber anti-slip sole and is integrated with an instep cover made of cowhide. Prepare 5 pairs of shoes obtained in this way and use them in the snow and cold regions of the Tohoku region.
When I let people wear it for 2 hours a day and continued it for a week, I never slipped or fell, and I was able to wear shoes with peace of mind.
