Description

[Detailed description of the invention] This invention prevents leaves from getting stuck to the anti-slip pin during wear, and also prevents small gravel, pebbles, mud, etc. This relates to the sole of footwear that prevents dirt from entering.

Conventionally, multiple anti-slip pins were protruded from the underside of the sole body of footwear,
There are footwear that is used for forestry work, hooking, etc.

However, this anti-slip pin usually protrudes by about 2 to 4 mm, so when walking in the forest, this anti-slip pin may come into contact with leaves (
To prevent this, a crater-shaped annular ridge (this annular ridge) was installed around the protruding anti-slip pin to prevent this from happening. The strips are molded from the same material as the sole body of the footwear.

), and these annular protrusions were used to flip out leaves stuck to the anti-slip pin.

Although the results were very good insofar as the annular protrusion was completely unbroken around its entire circumference, small gravel, pebbles, or mud could easily get into the recess formed by the annular protrusion. Eventually, the entire footwear became very heavy, and when small gravel, pebbles, and mud got into it, the original purpose of repelling stuck leaves could not be achieved. .

In order to restore this effect, all that is needed is to remove the clogged gravel, pebbles, and mud. As a result, it is very difficult in practice, and the inconvenience of having to do it every time it is used is a cause of further increasing the complexity.

Therefore, in this invention, a plurality of anti-slip pins are protruded from the lower surface of the sole body of the footwear, and an annular protrusion is provided around the anti-slip pins in which concave portions and convex portions are alternately continuous so as to surround the anti-slip pins. The leaves that stick to the tree are repelled by the convex part of the annular ridge.

To provide a footwear sole in which small gravel, pebbles, mud, etc. that are about to become clogged are removed from a concave part of an annular protrusion, thereby preventing clogging with leaves, small gravel, pebbles, mud, etc. It was developed for this purpose.

Next, an embodiment of the footwear sole according to this invention will be described based on the drawings. 1 is a rubber footwear sole body, and 2 is an anti-slip pin protruding from the underside of the footwear sole body 1.

In the drawings showing this embodiment, only one anti-slip pin 2 is shown, but the number of anti-slip pins 2 is the same as that used publicly in the past, and is present in large numbers.

Reference numeral 3 designates a bowl-shaped protrusion molded on the lower surface of the footwear sole body 1 from the same material as the footwear sole body 1 when the footwear sole body 1 is molded. It's jumping out.

Reference numeral 4 denotes an annular protrusion formed around the anti-slip pin 2 so as to surround the anti-slip pin 2, and this annular protrusion 4 is also made of the same material as the footwear sole body 1 when the footwear sole body 1 is molded. It has a bottom shape and is shaped so that recesses 5 and protrusions 6 are alternately continuous.

According to the shoe sole according to this invention, leaves stuck to the anti-slip pin are repelled by the annular ridges around the anti-slip pin, and small gravel, pebbles and mud that become clogged are naturally removed from the concave part of the annular ridges. It has the effect of being removed.

Moreover, even if it becomes clogged, it is immediately removed by the pressure applied to the annular protrusion when walking.

Furthermore, if the protruding end of the anti-slip pin and the tip of the annular protrusion are made at the same height, leaves will hardly get stuck in the tree, and even if they do, the force with which they are repelled will be stronger. be.
