Abstract

PURPOSE: To provide rubber-soled socks, in which the tiptoe part can be surely protected without hurting the light feeling and grounding feeling of rubber-soled sock itself, and which has heat resistance. CONSTITUTION: In rubber-soled socks formed in such a manner that a grounding sole 2 is fitted to an upper 1, protective bodies 3, 4 formed in such a manner as to cover the thumb part and the four-finger part of the upper 1 formed by leather, and a heat resisting layer 5 is formed on the surfaces of the protective bodies 3, 4. The formed protective bodies are put on the outsides of the thumb part and the four-finger part of the upper 1, and in such a condition, an adhesive is interposed between the upper 1 and the protective bodies 3, 4 to make both members adhere to each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground construction which can be used for civil engineering, construction sites, agricultural work, and various other purposes.

[0002]

2. Description of the Related Art In the conventional underground construction, an upper obtained by stitching cloth and a grounding bottom made of rubber or synthetic resin are fixed to each other by sticking or sewing. Such a basement is widely used because it has a light feeling due to its structure and an excellent ground contact feeling, but there is still a problem in protecting the foot when dropping an article on the toe.

For this reason, it is necessary to interpose a protective body made of steel plate or the like in the upper part of the toe part of each underground or to be crowned outward, as disclosed in Japanese Utility Model Publication No. Sho 36-11438 and Japanese Utility Model No.
It has already been known from Japanese Patent No. 32241.

However, of these, the former one, Shoko 36-1
The underground structure disclosed in Japanese Patent No. 1438 has a grudge that it takes time to manufacture because the protective body is interposed inside the upper.

In the case of the latter Japanese Utility Model Publication No. 3-32241, the protective body is separated by the thumb and the four fingers so that the lightness is not impaired and the manufacturing is easy, but since it is detachable, it can be used during use. I was afraid that I might not come off.

Further, since the protective body used for these is made of steel plate, it is inconvenient due to the increased weight of the toes in the underground where the weight is large and the lightness is required. . For this purpose, it is conceivable to use leather as a protective body, but this does not provide heat resistance like metal, and there is a concern that it may be damaged at work sites at high temperatures.

[0007]

In view of the above situation, the present invention does not increase the weight more than necessary even when the toe is provided with a protective body, and therefore does not impair the original feeling of lightness. It aims to provide a basement that does not impair heat resistance.

[0008]

That is to say, the gist of the present invention is that a protective body shaped to cover the thumb and four fingers is synthesized in the underground where the grounding bottom is attached to the upper. Along with being formed of resin or leather, a heat-resistant layer is formed on the surface of this protective body, and this is covered on the outside of the thumb and four fingers of the upper, and in this state, an adhesive is applied between the upper and the protective body. Every underground is characterized by being bonded by interposing.

[0009]

The present invention uses a protective body made of synthetic resin or leather, and is thus characterized by being lightweight and not impairing the feeling of lightness, and having heat resistance due to the presence of a heat-resistant layer on the surface.

A description will be given below with reference to the drawings of the embodiments.
In these examples, the protective body has a thumb part and four finger parts which are separate bodies, but of course, a protective body in which both finger parts are integrated may be used.

FIG. 1 shows an example of the underground construction of the present invention, and FIG. 2 is an enlarged sectional view taken along the line AA 'of FIG. 1, FIG. 3 and FIG.
FIG. 3 is a cross-sectional view showing an embodiment of a protective body used in the present invention.
The protective body shown in FIGS. 3 and 4 is a thumb protective body, but the four-finger protective body is substantially the same although the shape is slightly different, and the illustration thereof is omitted.

In these figures, 1 is an upper, and this upper 1 is composed of a front cloth, a back cloth and an insole.
These are sewn with cloth. Reference numeral 2 denotes a grounding bottom made of rubber or synthetic resin, which is fixed to the upper 1 by a hanging type or a sewn type to form an underground basement. An uneven surface, which is generally called a tread pattern, is formed on the ground contact bottom 2.

According to the present invention, such a thumb protector 3 is formed on the toe of each subterranean base in a shape corresponding to the outer shape of the thumb formed of synthetic resin or leather, and four separate bodies are provided. A four-finger protector 4 shaped into a shape corresponding to the outer shape of the finger,
The thumb and four fingers are crowned and adhered to the outside, and the two protective bodies 3 and 4 each having a heat resistant layer 5 formed on the surface thereof are used.

FIG. 3 shows the cross section of the thumb protector 3 used in the present invention. The protectors 3 and 4 including this are synthetic resin such as reinforced plastic or leather such as cowhide impregnated with synthetic resin. These are used by shaping them into a shape corresponding to the outer shape of the thumb or four fingers. Then, a heat resistant sheet such as a steel plate or asbestos is similarly formed and adhered to this surface, or a heat resistant coating is applied to form the heat resistant layer 5.

In the case of the thumb protector 3 shown in FIG. 4, streak-like reinforcing ribs 3A are formed. By providing such ribs 3A, rigidity can be imparted to the protector. It will be possible to make it thinner, and it will be possible to make it even lighter. The reinforcing rib 3A is not limited to the streak shape, and may be provided in a lattice shape.

When the heights of both protective bodies 3 and 4 are set so that the bottom surface thereof is substantially equal to the bottom surface of the grounding bottom when they are adhered, when the pressure is applied from above, the toe parts keep their original shape. It is convenient because it can be protected.

Although not shown in the drawings, if a cushioning sheet is interposed between the front cloth and the back cloth of the portion corresponding to the toe where the upper protective body is to be crowned, not only it helps to protect the toe but also the protective body is crowned. It is convenient in manufacturing because the upper can have a certain tension when being made. In addition, such a cushioning sheet may be interposed by being adhered to the inner surface of the upper cloth or the inner surface of the back cloth of the upper.

[0018]

EFFECTS OF THE INVENTION The present invention is constructed as described above, and although the protective body is provided on the toe portion, the protective body is made of synthetic resin or leather and is lightweight and does not impair the feeling of lightness. Moreover, the presence of the heat-resistant layer on the surface has an advantage that heat resistance can be exhibited. In addition, when the thumb and the four fingers are separated as the protective body, there is an advantage that there is no restriction on the movement of both fingers and a more light feeling can be maintained.
