Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a steel toe pad that is disposed at the toe portion of a shoe to protect the foot.

<Conventional Example and Problems> Conventionally, there is a shoe shown in FIGS. 6 and 7 in which an overcap type steel toe core is disposed in a shoe.

That is, in the shoe shown in FIG. 6, a shoe last 101 with an insole temporarily fixed thereon is coated with an upper 102, the lower edge of which is joined to the insole, and a steel toe core 1 is attached to the toe part.
03 is fitted, and then a rubber outsole 104 is bonded and vulcanized to the lower edge of the upper and the lower edge of the steel toe core using an adhesive.

In this case, the steel toe core 103 and the outer sole 104
The adhesive strength of the toecap 1 is weak and the toecap 1
03 was easily peeled off from the outsole 104.

In addition, the one shown in FIG. 7 has a rubber outsole 10.
In the vulcanization molding step 4', the lower edge of the steel toe core 103' is embedded in the outsole 104', and the last 10
1' is covered with an upper leather 102', and the lower edge of the upper leather 102' is adhered to the midsole, which is inserted into the toe cap 103' of the toe portion and fixed to the outsole 104'.

In this case, the peeling action of the steel toe core 103' can be prevented, but the entire outsole is molded from a rubber material as in the case of FIG. 6, which increases the weight of the entire shoe. There are drawbacks.

<Means for solving the problems> The present invention was proposed in order to solve the above-mentioned drawbacks.With a simple structure, it is possible to prevent the steel toe core from peeling off, and the weight of the shoe can be reduced. The purpose of the present invention is to provide a steel toe core that can contribute to the manufacture of shoes that are comfortable to wear.

The purpose of the above is "a steel toe made by embedding and fixing the lower edge of a steel toe core in a hard rubber material formed into a roughly horseshoe shape, and configured so that the hard rubber material can be combined as a part of the outsole. This is achieved through the ``core''.

<Example> Hereinafter, the present invention will be explained based on an example shown in the drawings.

As shown in FIGS. 1 and 2, the steel toe core 1 of the present invention has its lower edge embedded and fixed in a hard rubber material 2 formed into a substantially horseshoe shape.

FIG. 3 shows the shoe in its formed state, with 3 indicating the upper, 4 the midsole, and 5 the outsole.

When molding a shoe, the upper 3 and the midsole 4 are hung and covered with a shoe last, and the upper 3 is covered from the outside with a steel toe core 1. Next, this is placed in a mold for forming an outsole, and the outsole forming material is injected into the mold to form the outsole 5.

The shoe formed in this way has a lightweight and elastic outsole 5 made of foamed polyurethane, is comfortable to wear, and can be worn for a long time.

FIG. 4 shows another embodiment in which the lower surface of the hard rubber material 2' is exposed on the bottom surface of the outsole 5'. In this case as well, as shown in FIGS. 1 to 3, the lower edge of the steel toe core 1 is embedded in a hard rubber material 2' formed into a substantially horseshoe shape.

In the figure, 3' is the upper and 4' is the midsole.

In the shoe thus formed, the bottom surface of the hard rubber material 2' is exposed to the bottom surface of the outsole 5', so that the slippage of the hard rubber material 2' can be prevented.

<Effects> The present invention has the above configuration, and the lower edge of the steel toe core is embedded in a roughly horseshoe-shaped hard rubber material, so the steel toe core is placed when the hard rubber material is vulcanized and formed. By doing so, they can be integrated safely in terms of strength.

In addition, even if the outsole is molded from foamed polyurethane, the adhesive strength between the polyurethane and the hard rubber material is excellent, so the steel toe core can be safely attached due to its strength, and there is no peeling effect like in the past. . Moreover, even when the steel toe pad receives a strong impact, the impact is absorbed by the hard rubber material, so even if the outsole is made of a lightweight material with good cushioning properties, the foot can be adequately protected.

Therefore, according to the present invention, even shoes having steel toe cores can be made lightweight and have practical value such as being comfortable to wear.
