Abstract

PROBLEM TO BE SOLVED: To strongly fix a protector to the toe part of an upper by fixing the toe protector, which is formed for covering the toe part, through an adhesive agent by covering the toe part of the upper, in rubber-soled socks with the big toe separate for which the protector is fixed to the toe part. SOLUTION: The rubber-soled socks with the big toe separate are composed of uppers 1, ground soles 2, thumb toe protectors 3 and four-finger toe protectors 4, and the upper 1 is composed of ordinary front cloth, rear cloth and inner sole and is fitted to the ground sole 2, which is composed of rubber or synthetic resin, by hanging or sewing. Then, the respective protectors 3 and 4 are fixed to the toe parts of rubber-soled socks while covering these toe parts, but in this case, the adhesive agent is interposed on the inner faces of both the toe protectors 3 and 4 and the protectors are adhesively fixed to the upper 1. Thus, the protectors can be stably and strongly fitted to the upper 1 without using any special instrument and are prevented from being deviated or detached at random.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subterranean construction which can be used for earthworks, construction sites, agricultural work and 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 a sticking method or a sewing method.
Such an underground structure is widely used because it has a light feeling due to its configuration and has an excellent feeling of contact with the ground, but there is still a problem in protecting the foot when an object is dropped on a toe or the like.

For this reason, it is possible to interpose a protective body made of a steel plate or the like inside the upper or to crown the body outward without impairing the movement of the fingers of the toes under the ground.
It has already been proposed by Japanese Patent No. 438 and Japanese Utility Model Publication No. 3-32241.

However, of these, the former one, Shoko 36-1
In the case of the underground shown in Japanese Patent No. 1438, since the protective body is interposed inside the upper, it takes time to produce and there is a grudge that it cannot be provided at low cost.

[0005] In the latter case, Japanese Utility Model Publication No. 3-32241, the protective body is a separate body for the thumb and the four fingers, and the lightness is not impaired and the production is easy, but it is detachable. May give you anxiety that it may come off during use. Since it is required to be light and stable every time underground, even when attaching a protective body, it is firmly fixed to the upper so that it does not come off unintentionally, and special equipment etc. at the time of installation It is desired to be concisely finished without using.

[0006]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is a stability in which lightness is not impaired, and moreover, the protector is firmly adhered to the upper toe part to ensure the protection of the toes. It is intended to provide a good basement every time.

[0007]

That is, the gist of the present invention is that it is shaped to cover the tip of the toe in the underground where the grounding bottom is attached to the upper and the protective member is fixed to the tip of the toe. In each basement, the toe protector is capped on the upper toe part and fixed by interposing an adhesive between them.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below based on illustrated examples. FIGS. 1 to 3 show a subterranean excavation of a first embodiment of the present invention.
Is an upper, 2 is a grounded bottom, 3 is a thumb toe protector, and 4 is a four finger toe protector. Of these, the upper 1 is usually composed of a front cloth, a back cloth, and an insole, and is attached to the grounding bottom made of rubber or synthetic resin by a suspending type or a sewing type to construct an underground structure. There is. An uneven surface generally called a tread pattern is formed on the bottom surface of the ground contact bottom 2.

The toe protector in the above-described embodiment is shaped separately from the toe protector 3 of the thumb portion, which is formed in a shape corresponding to the outer shape of the thumb portion, and the outer shape of the toe portion of four fingers. And a four-finger toe protector 4. 2 and 3, the thumb toe protector 3 is shown as a representative example, but the four finger toe protector 4 is substantially the same as the thumb toe protector 3 although the shape is slightly different. Yes, illustration is omitted.

In the present invention, the thumb toe protector 3 and the four finger toe protector 4 are capped and fixed to the toe of each such underground. At this time, both toe protectors 3 are provided. ,
An adhesive is interposed on the inner surface of 4 to adhere and fix it to the upper 1.

In this example, since the thumb toe protector 3 and the four finger toe protector 4 are fixed as described above, the upper 1 can be stably and firmly attached without using any special equipment or the like. It does not slip off or come off, and does not impair the original feeling of lightness and wearability every time you wear it. In particular, since the toe protector is composed of the thumb part and the four-finger part separately, each of the fingers can be moved separately, and a lighter feeling can be obtained and wearability is improved.

FIG. 3 and FIG. 4 show a second embodiment of the present invention, which uses an integrated toe protector 5 shaped to integrally cover the thumb and four fingers. . Also in the case of this example, the integrated toe protector 5 is crowned outside the toe of the upper 1 and is fixed by interposing an adhesive therebetween. As a result, it is possible to obtain an underground structure in which the integrated toe protector 5 is firmly and stably fixed to the toe portion of the upper 1.

The toe protectors 3, 4, 5 used in the present invention are
Steel plates, reinforced plastics, and cowhide impregnated with synthetic resin are used and shaped according to their respective shapes.

If the height of the toe protectors 3, 4, 5 from the upper is set to be substantially equal to the bottom surface of the grounding bottom 2 when fixed, the toe parts when pressure is applied from above. This is convenient because the toes can be protected while maintaining the original shape of the.

Although not shown, a cushioning material interposed between the toe protector and the upper part or between the front cloth and the back cloth can further serve for protecting the fingertip. As the cushioning material, for example, thick cloth or non-woven fabric is used.

[0016]

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned structure, the toe protector can be firmly fixed to the upper, and even when it comes into contact with or collides with an article during wearing, it is displaced. It does not come off, it can protect the toe stably and reliably, and it has the advantage that it does not impair the original wearability and agility every time it is applied to the basement. There is a feature that can be done.
