Description

[Detailed Description of the Invention] The present invention relates to a shoe sole having anti-slip properties and wear resistance.

In general, synthetic resin soles have excellent abrasion resistance, but are more slippery than rubber soles, while rubber soles have anti-slip properties but are slightly inferior in abrasion resistance. are doing.

Therefore, synthetic resin soles cannot be said to be sufficient in terms of anti-slip properties for shoes such as ballet shoes, athletic shoes for school children, or cold-weather shoes that require more than normal wear resistance and anti-slip properties.

In order to improve the above-mentioned drawbacks, measures such as installing a rubber anti-slip piece on the bottom of the synthetic resin shoe sole have been tried, but the adhesion between rubber and synthetic resin is insufficient, and the area around the rubber anti-slip piece is sloping. It is common for the anti-slip piece to come off during use if there are irregularities or irregularities.

The present invention consists of a plate-shaped rubber or synthetic tsuba, which is equipped with a tsuba having an appropriate number of through holes around the main body, the thickness of the tsuba is smaller than the thickness of the main body, and the lower surface of the tsuba is recessed from the ground surface of the main body. This relates to a shoe sole characterized in that a resin anti-slip piece is positioned at a predetermined location, the entire brim of the anti-slip piece and the upper surface of the main body are embedded, and a synthetic resin finger part is integrally molded. Since the flange is provided around the periphery and an appropriate number of through holes are buried in the flange, the synthetic resin integrally molded around the anti-slip piece penetrates through the holes. is not used to leaving.

The present invention will be described below with reference to drawings showing embodiments thereof.

First, to explain the anti-slip piece of the present invention shown in FIG. 3, the anti-slip piece 1 has a main body 2 and a flange 3 having an appropriate number of through holes 4 provided around the body made of rubber or synthetic resin with high anti-slip properties. (
For example, it is integrally molded with polyurethane elastomer).

Further, the thickness of the collar 3 is smaller than that of the main body 2, the lower surface of the collar is recessed from the ground plane of the main body, and the upper surface of the collar 3 and the upper surface of the main body 2 are on the same plane.

That is, the upper surface 5 of the anti-slip piece 1 forms a flat surface.

Further, the ground plane (lower surface) 6 of the main body 2 has an uneven surface in order to further improve the anti-slip property.

The shape of the anti-slip piece 1 is determined depending on the shape of the intended shoe sole, but the thickness of the main body 2 is usually such that the contact surface 6 is exposed at the bottom of the shoe sole, as shown in FIG. It has a thickness that allows it to be reliably embedded in the sole of the shoe, and the outer shape is large enough to allow the collar 3 to be sufficiently embedded between the periphery of the ground plane 6 and the periphery of the sole, as shown in Figures 1 and 4. As shown in Figure 1, it is constructed as two anti-slip pieces for a shoe sole with separate contact surfaces, and as shown in Figure 4, it is configured as two anti-slip pieces, as in athletic shoes, where the contact surface is continuous. It is constructed as one anti-slip piece for the sole of the shoe.

The sole of the present invention has the above-mentioned anti-slip piece 1 integrated with a synthetic resin sole 7 so that only its ground surface 6 is exposed and the periphery of the anti-slip piece 1 including the collar 3 and top surface 5 is buried. A preferred synthetic resin for forming the synthetic resin bottom portion is polyurethane.

Note that the through holes 4 are provided at appropriate intervals, but by making the shape of the holes elongated in the circumferential direction of the main body 2 as shown in the figure,
Even if the width of the collar 3 is narrow, it can be more reliably integrated with the synthetic resin bottom 7 through the through hole 4.

The means for integrally molding the anti-slip piece 1 and the synthetic resin bottom 7 is not particularly limited, but a conventional method may be used.

That is, first, the upper surface 5 of the anti-slip piece 1 is worn out, then the drawn upper surface 5 is treated with a primer, and the adhesive is applied to the upper surface 5, and then the anti-slip piece 1 is placed in a predetermined position in a predetermined mold. The sole is integrally molded by injecting synthetic resin into this mold.

The mold used in this case is determined depending on the shape of the intended shoe sole, and can be used as is or with some modification of a conventional mold for the sole shape.

It should be noted that the size and shape of the sole and anti-slip piece of the present invention are not limited to those in the embodiments, and can of course be modified in various ways depending on the purpose.

The sole of the present invention is provided with a flange 3 having a large number of through holes 4 as mentioned above as an anti-slip piece 1, and this flange 3 is embedded in a synthetic resin sole 7, and the flange 3 and the synthetic resin sole 7 are connected to each other. is through hole 4
Unlike conventional shoe soles that use anti-slip pieces with slopes and unevenness around the anti-slip pieces, there is no risk of the anti-slip pieces falling off. As shown in the example, by configuring the upper surface to be on the same plane and making the through hole an elongated hole, the integration of the anti-slip piece 1 and the synthetic resin bottom part 7 is further ensured, and molding is facilitated. Therefore, the provision of the anti-slip piece can sufficiently improve the drawbacks of the synthetic resin bottom.
