Description

[Detailed description of the invention] <Industrial application field> The present invention relates to the improvement of work shoes, and is extremely effective for simple work shoes that are often worn by stepping on the heel of the shoe.

<Prior Art> Conventionally, the heel of work shoes is constructed by sewing the leather on both the left and right sides of the outer leather in the vertical direction at the rear end of the heel, which is the rearmost part. When wearing these work shoes, the leather material itself is hard and the laces are difficult to tighten, so the heel of the shoe is often pressed down.

<Problem that the invention aims to solve> When wearing work shoes, it is common for work shoes to be worn by stepping on the heel of the shoe, or with the heel still being stepped on, especially with work shoes for simple work. It is a case. However, when wearing shoes in this way, the shape of the heel cannot be maintained, and the threads at the seam at the rear of the heel break, often resulting in immediate damage to the heel. It was. For this reason, there were many cases where only the heel part was damaged and the shoe became unusable, even if the sole, upper part, and sides were completely undamaged and the work shoe was fully usable.

Therefore, there is a need for work shoes that are less susceptible to damage to the heel than conventional products even if the heel is stepped on.

<Means for Solving the Problems> The present invention provides work shoes in which the shape of the heel does not deform or break even when the heel of the work shoe is stepped on.

That is, the moon-shaped core 7 is made up of a T-shaped horizontal core 4 made of a soft elastic material and a vertical core made of a hard elastic material.
These work shoes are characterized in that the heel part 2 is covered with a leather material 8 in a bag shape.

<Embodiment and operation> The outer leather part of the work shoe consists of three parts from the front of the shoe: a toe part 6, a front waist part 1, and a heel part 2, and the bottom is made up of a normal sole part 5. The heel part 2 has a moon-shaped core 7 composed of a vertical core 3 located at the center of the rearmost part, and a horizontal core 4 attached to the vertical core 3 in a T-shape at the upper end of the vertical core 3, and a leather material 8. It is covered in a bag. The leather material 8 of the heel portion 2 is sewn to the front waist portion 1 on the left and right sides of the shoe.
The vertical core 3 constituting the moon-shaped core 7 is made of a hard elastic body, and is made of synthetic resin or hard rubber that is somewhat hard and resistant to bending. The horizontal core 4 is made of a soft elastic body, and is made of extensible synthetic resin or soft rubber. As mentioned above, heel part 2
In this case, a moon-shaped core 7 consisting of both a vertical core 3 made of a hard elastic material and a horizontal core 4 made of a soft elastic material attached to the vertical core 3 in a T-shape is covered with a leather material 8. It has a structure in which a moon-shaped core 7 is housed in a bag made of leather material 8.

Since the work shoes of the present invention have the above structure, they have the following effects.

In other words, when the heel of the work shoe is stepped on, the vertical core portion of the moon-shaped core resists the pressure and tries to return to its original shape, and the horizontal core portion spreads the pressure from above horizontally. try to make it happen As a result, while the object is being stepped on, a force acts to resist the force of stepping on it and maintain its original shape, and when it is released after being stepped on, it immediately returns to its original state.

<Effects of the invention> As described above, the present invention has the following effects. That is, the T-shaped moon-shaped core of the heel part maintains the shape of the heel part so that it always fits the shape of the foot, so the heel part can withstand being stepped on. Further, since the moon-shaped core is wrapped in a bag-like leather material and has no seam at the rear end, damage to the seam portion due to repeated trampling can be prevented. In addition, the elastic moon-shaped core disperses the pressure of stepping on the shoes and prevents stress from being placed on specific areas of the heel, resulting in significantly improved durability, especially in the heel area.
