Description

[Detailed explanation of the idea] [Industrial application field] This idea is related to sports shoes.

[Conventional technology]

Sports shoes worn when playing sports such as baseball are often made of cowhide. However, sports shoes made of cowhide are flexible and comfortable to wear, but are prone to scratches.
As the product is used, many scratches may occur on the surface of the lower back skin, and it may even break. For this reason, conventionally, a padding layer (auxiliary layer) is sewn in advance over the easily torn portion.

In addition, in relatively high-quality sports shoes, the upper body is sewn to the sole leather with a thin leather interposed between them, and at that time, the lower leather is inserted along a wooden pattern and sewn together by blind stitching. Therefore, this work requires considerable skill and effort.

Therefore, it is described in Utility Model Application Publication No. 49-18739,
As shown in FIGS. 3 and 4, the upper part 20 is made of a highly abrasion-resistant synthetic resin such as polyurethane, and is shaped like the edge of a shoe heel, and both side parts 21 are bulged and the bottom part is formed into a bent side 24. Sports shoes have been proposed in which a waist ball 23 is placed on the outside of the heel and sewn or glued to the upper.

[Problem that the invention attempts to solve]

The sports shoes mentioned above have a waist ball 2 that forms the waist skin.
3 is made of wear-resistant synthetic resin molded product,
The abrasion resistance of the waist skin, which is easily damaged, is improved, and since the bent piece 24 can be used as a hooked piece, there is an advantage that the conventional work of hooking it in and blind stitching is eliminated.

However, the upper part 20 of the waist ball 23 forms the edge of the heel opening of the shoe, and the upper part bulges forward.

The edge of the shoe opening is usually at the same height as or higher than the upper end of the calcaneus, and the lower part of the bulge 25 is constricted like the waist ball 23 (section a in the figure). This is to make the width of the part a narrower to make it easier to bend to some extent and to move the bulge 25 along the movement of the foot as shown by the chain line.

When wearing shoes, the bent part at the rear of the ankle is the connection part between the calcaneus and the Achilles tendon, so the bulging part 25 of the waist ball 23 is located considerably above the Achilles tendon part.

In this way, the edge of the shoe's opening is located above the top of the heel bone, and if the edge of the shoe's opening is made of a wear-resistant synthetic resin molded product that is much harder than cowhide etc. When worn), this hard shoe edge can dig into the Achilles tendon area, easily causing damage such as blisters. In particular, when the bulging portion 25 of a molded product is formed like the above-mentioned waist ball 23, the range of its bite is wide and the degree of damage becomes large.

[Purpose of invention]

This invention aims to eliminate damage caused by using a wear-resistant synthetic resin molded product, with the above points in mind.

[Means to achieve the purpose]

In order to achieve the above object, in this invention, the waist skin piece covering the outer periphery of the heel is shaped like a wall rising from the outer periphery of the heel of the shoe sole, and the upper edges thereof are opposite to each other from the left and right front ends on the sole surface of the shoe. The height gradually increases toward the sides, and the top end is lower than the upper end of the calcaneus when worn, and it has a piece that protrudes laterally over the entire length of the lower edge, which is connected to the sole of the shoe. It is made of a wear-resistant synthetic resin injection molded product such as polyurethane.

[Effect]

Sports shoes constructed in this way are worn in the same way as before, but when worn, the molded lumbar skin piece is lower than the upper end of the calcaneus, and the ankle flexes between the calcaneus and Achilles tendon. Because it is done at the joint, the waist skin piece does not dig into the back of the ankle.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIG. 2, the sports shoes A of this embodiment include a tipped leather piece 1 that covers the upper surface of the toe part of the sole, a waist leather piece 2 that covers the outer periphery of the heel, both pieces 1, 2
In sports shoes consisting of an upper leather piece 3 interposed between
However, the curved surface 1a bulges out from the outer periphery of the toe of the shoe sole.
Molded from a wear-resistant synthetic resin such as polyurethane, the part has a protruding part 1b extending rearward on both sides from the center part of the inner edge from the center part c of the inner edge connected to the curved upper 3 to the sole. In addition, the waist skin piece 2 has a wall shape rising from the outer periphery of the heel of the shoe sole, and its upper edge gradually decreases in height from the center b to the left and right front. It is pre-constructed from a wear-resistant synthetic resin molded product such as polyurethane in a shape that reaches . The front cover piece 1 and the waist cover piece 2 are molded by injection molding.

As shown in FIG. 2, the tipped skin piece 1 is formed larger than the conventional tipped skin, and is integrally provided with a thin skin 5 that protrudes laterally and is sewn to the bottom skin 4. , a string hole 6 is integrally provided.

The waist skin piece 2 is integrally provided with a thin skin 7 similar to the above-mentioned tipped skin piece 1, and a plurality of vertical grooves 8 are formed to improve cushioning properties.

Next, the front skin piece 1 and the waist skin piece 2 are sewn to the sole skin 4, and at the same time, each member such as the upper skin 3 made of cowhide, the tongue skin 9, the city skin 10, and the waist lining skin 11 are sewn, and then the strings are sewn. Add 12 to complete Sports Shoes A.

In addition, in sports shoes where the lower edge of the instep is inserted between the outsole and the midsole and bonded, the thin skins 5 and 7 are omitted for both the tipped skin piece 1 and the waist skin piece 2, and the conventional A protruding piece that becomes a hanging edge is connected inward. In addition, the tipped leather piece 1 has a string hole 6
The size of the extension portions on both sides can be selected as appropriate.

The sports shoe is applicable to baseball shoes, soccer shoes, and various other sports shoes.

In sports shoes constructed as described above, the toe area, both sides of the upper skin, and the waist skin area, which are most likely to be damaged during exercise, are made of abrasion-resistant synthetic resin injection molded products, so they are different from conventional leather products. It is less prone to scratches and wrinkles than other fabrics, and can also be easily attached to thin skins, so the traditional processes such as fishing using a wooden pattern and blind stitching, which require skill and a lot of effort, can be omitted. , sewing is streamlined. Furthermore, since it is a molded product, the vertical grooves 8 can be easily formed, and the cushioning properties can be improved.

Furthermore, when worn, the waist skin piece 2, which is a molded product that is harder than cowhide, is positioned lower than the upper end of the calcaneus, so the waist skin piece 2 does not dig into the rear part of the ankle.

[Effect of idea]

This invention, constructed as described above, solves the problems of shoes made of wear-resistant synthetic resin injection molded waist skin pieces, so it not only has wear resistance, shape retention, and workability, but also improves wear resistance. You can get comfortable sports shoes.
