Description

[Detailed description of the invention] This invention is mainly based on black toe leather (so-called pea film) that covers mainly the inner surface of the toe part of the instep of baseball rain boots.
This is related to the improvement of.

Regarding the improvement of the toe reinforcing piece of conventional baseball rain boots, the lower bent piece part that joins with a part of the bottom of the baseball rain boots, and the peripheral side part such as the inner side part of the upper part, etc. Except for the upper side of the toe black leather, which consists of the peripheral side to be covered and the upper side that covers the upper part of the peripheral side, the lower folded piece and the peripheral side, or the above folded part. A large amount of liquid polyurethane compound with good permeability (relatively increases hardness, improves abrasion resistance, and strengthens the tangle of leather fibers) in designated areas, such as the horseshoe-shaped strip bonded to the bottom side of the piece. To provide a toe black leather piece for baseball rain boots which is impregnated with a material (preparation material) which does not put pressure on the instep or the inside of the instep, does not cause any injury to the foot, and has good durability.

The black toe leather of the baseball rain boots mentioned above has a thin film of urethane elastomer mainly on the outer surface of the periphery, the folded piece, or these and the horseshoe-shaped strip, so it has good water resistance and shape retention, and has a good appearance. However, if only a thin film layer and a permeable layer of the urethane elastomer are used, the periphery of the black toe leather may be worn away due to friction caused by repeated contact with the ground, and holes may be formed, or the urethane elastomer may Since the coating layer has a flat surface, it has been impossible to avoid defects such as slipping and ruining the pitching form of the wearer of the baseball rain boots, that is, the baseball player.

In order to overcome the defects of the black toe leather of the present invention, the black toe leather of the baseball shoe has a further reinforcing layer mainly on the periphery of the black toe leather, thereby improving its contact wear resistance with the ground, etc. Not only can this be further strengthened, but it can also be provided with anti-slip properties to eliminate the risk of disrupting a baseball player's pitching form, and by applying a desired color, the exterior appearance can be made more colorful. This is what we are trying to offer as something that can be improved.

The present invention, which can achieve the above objects, will be described in detail with reference to the drawings as follows.

That is, the present invention is based on the first drawing and II and the second drawing and II.
As shown in , most or part of the toe black leather piece 4 is made up of at least the lower bent piece 2, the peripheral side 1 connected to this, and the upper side 3 connected to the peripheral side 1. In a black toe leather main body a on which a permeation layer 5 of a liquid urethane elastomer compound or a film 6 connected thereto is formed, a reinforcing layer C of urethane elastomer is formed mainly on the outer surface of the peripheral side 1 of the black toe leather main body a. Furthermore, projections 8 are formed on the outer surface of the reinforcing layer C of the urethane elastomer. It is characterized by forming anti-slip elements such as recesses 9 or cuts 10.

That is, as shown in the first drawing, the toe black leather 4 is made of, for example, the back side of natural leather or synthetic leather (the rough fiber texture side opposite to the front side called the silver side) and is the sole of baseball shoes B. A lower folded piece 2 corresponding to the bent piece 2, a peripheral side 1 that is connected to the folded piece 2 and covers mainly the peripheral side of the toe side of the upper of the baseball shoe B, and a toe of the upper of the baseball shoe B. Toe black leather piece 4 having an upper side 3 covering the upper side of
Alternatively, as shown in FIG. 1 II and FIG. 2 III, a horseshoe-shaped band made of natural leather or synthetic leather cut into a horseshoe shape is attached to the lower surface side of the folded piece 2 of the toe black leather main body a. It can also be formed into objects.

The reinforcing layer C of the urethane elastomer can be formed of a molded product of a liquid urethane elastomer compound having strong abrasion resistance and having suppressed fluidity by mixing an inorganic filler such as ultrafine silica particles.

When the urethane elastomer reinforcing layer C is formed in this way, its fluidity is suppressed, so it can be thickly adhered to the outer surface of the peripheral side part 1 mainly made of black toe leather, and it can be formed into a layer of a desired thickness. It has the advantage of being able to form.

Therefore, in the black toe leather A of the present invention, as described above, a reinforcing layer 5 of urethane elastomer is further formed on the permeable layer 5 of urethane elastomer formed on the peripheral side 1 of the black toe leather main body a or on the coating 6 connected thereto. Therefore, it is possible to further improve the abrasion resistance and toughness of the peripheral side portion 1, which is the most susceptible to wear and tear as toe black leather.

Furthermore, there are protrusions 8 and recesses 9 on the urethane elastomer reinforcing layer C.
Alternatively, since the cut 10 is formed, the protrusion 8 and the recess 9 exert a strong anti-slip effect, and the ground holding power of the toe part is maximized, especially in pitching motions in baseball where the toe part is used as a support, or in batting motions. Pitching form that takes advantage of the limit.

This can greatly contribute to improving the stability of batting form.

The reinforcing layer C of the black toe leather A can be formed to have a desired color by, for example, adhering the aforementioned liquid urethane elastomer compound mixed with an appropriate pigment in advance.
It is possible to provide black toe leather A for baseball shoes with high added value as the black toe leather A has a better appearance.
