Embodiment 1

[0080] Adding a vulcanizing agent, a vulcanization accelerator, an antioxidant, a filler, and a coloring agent to a rubber material composition composed of natural rubber and styrene butadiene rubber, and performing roll kneading to obtain a composition for forming a sole member thing. Low hardness (approximately 45 to 55), medium hardness (approximately 56 to 65) and high hardness (approximately 66 to 80) Three different levels of sole member composition.

[0081] The sole member compositions of the three hardness levels were formed into sheets having a thickness of about 10 mm. Each sheet is cut to a predetermined width and length, resulting in slices for sole forming members. Then, the non-slip sole 1 as shown in FIG. 1 is formed from the slices. The ground protrusion 3 is provided with an inclined reinforcing portion 5 having an inclined angle α of about 45°. The average opening angle β of the V-shaped protrusions is about 96°. The surface roughness of the ground bump...

Embodiment 2

[0086] A vulcanizing agent, a vulcanization accelerator, an antioxidant, a filler and a coloring agent are added to a composition composed of a mixture of standard natural rubber and polybutadiene rubber for shoe soles, followed by roller kneading to obtain a shoe sole material. This material is used to form a non-slip sole 1 as shown in FIG. 7 . The inclination angle α of the inclined reinforcing portion 5 , the opening angle β of the V shape of the grounding protrusion 3 , the surface roughness of the grounding protrusion surface 4 , and the interval 8 in the longitudinal direction are the same as in the first embodiment. The JIS-A hardness of the ground protrusion 3 is set to medium hardness (56 to 65°). FIG. 12 shows the results of measuring the kinetic friction coefficient of the thus obtained anti-slip sole in the same manner as in Example 1. FIG. For comparison, the coefficient of dynamic friction of the conventional shoe sole used in Example 1 is also shown in FIG. 12...

Abstract

The slip resistant shoe sole 1 of the invention comprises a plurality of ground contact projections 3 formed on the ground contact side of the sole base 2 with a predetermined gap between adjacent ground contact projections 3 in the longitudinal direction of the base 2, the ground contact projections 3 having a V-shaped horizontal cross section, having inclined reinforcements 5 provided at the roots of the ground contact projections 3 on the base 2, and being formed using an elastomeric polymer with a JIS-A hardness of 45 to 80 as measured at 20 DEG C.

Description

technical field [0001] The present invention relates to a non-slip sole that makes even smooth or mirror-finished floor surfaces, floor surfaces that are slippery due to being covered with water films, oil films, soap films, etc., floor surfaces made of stone in buildings, etc., It is also possible to walk relatively stably on metal surfaces such as manhole covers and gutter intake grilles. Background technique [0002] Various proposals have been made to improve the slip resistance of non-slip soles. [0003] For example, it is known to impart an edge effect to the sides of the protrusions by thermally spraying a hard material onto the protrusions of an embossed surface formed on an outsole base and then removing the hard material from the contact surface of the protrusions Sole (Patent Document 1). [0004] It is also known to have soles with magnetic microflakes oriented upwards with respect to the ground contact surface of the embossed protrusions, thereby creating gri...
