DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, an underground base is manufactured by bonding an upper obtained by sewing a fabric and a grounding bottom made of rubber or synthetic resin by a sticking or 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.

[0003] For this reason, a protective body made of a steel plate or the like is interposed in the upper part of the toe under the base or is covered with the outer part of the upper part.
It is already known from JP-A-32241.

[0004] However, the former of these is the former No. 36-1
At the basement shown in Japanese Patent Publication No. 1438, there was a grudge that it took time and effort to make the protective body interposed in the upper part.

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 protective body is easy to manufacture. There was a fear of giving anxiety about coming off.

[0006] Since a light and stable feeling is required in each basement, even when a protective body is attached, it must be securely fixed without detaching from the upper. At the same time, easy production and efficient production are required.

[0007]

DISCLOSURE OF THE INVENTION In view of the above situation, the present invention can be easily manufactured without impairing the original feeling of lightness underground, can securely protect the toes, and can securely mount the protective body. It is intended to provide a good basement every time.

[0008]

SUMMARY OF THE INVENTION That is, the gist of the present invention is to provide a thumb protector formed in a shape corresponding to the outer shape of the upper thumb in each basement where a protector is attached to the upper toe. A body and a four-finger protective body separately formed into a shape corresponding to the outer shape of the four-finger part , and an engagement portion is formed on each bottom surface , and the two protective bodies are formed. With the upper part of the thumb and the four fingers of the upper part covered, and the above-mentioned engaging part is engaged with a concave part provided at a corresponding position on the bottom surface of the grounding bottom. Each basement is characterized by being bonded with an adhesive.

[0009]

According to the present invention, since the protective body is separated into the thumb and the four fingers, there is no restriction on the movement of both fingers, so that the feeling of lightness is not impaired. The toe portion is firmly attached to the upper in combination with the engagement of the mating portion, so that the toe portion does not come off and separate during use, and the toe portion can be reliably protected for a long period of time.

Hereinafter, description will be made with reference to the drawings of the embodiment.
FIG. 1 shows an example of the basement of the present invention, and FIG.
FIGS. 3 to 5 are enlarged cross-sectional views taken along the line AA ′, and FIGS. Although the protective body shown in FIGS. 2 to 5 is the thumb protective body 3, the four-finger protective body 4 has a slightly different shape but is substantially the same, and is not shown.

In these figures, reference numeral 1 denotes an upper, and the upper 1 comprises a front cloth 1A, a back cloth 1B and an insole 1C, which 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 sewing type to form a basement. The bottom surface of the ground base 2, while concave engagement portion of the protective member is engaged as will be described later is provided, which is intended groove toward the inward from the edge to the corresponding portions of the ground base 2 bottom Can be achieved, but it can also be formed by utilizing the uneven tread pattern usually provided on this surface.

The present invention provides a thumb protector 3 having a shape corresponding to the outer shape of the thumb on the toe of each basement.
And a four-finger protective body 4 separately formed in a shape corresponding to the outer shape of the four-finger part, which covers the thumb part and the four-finger part outside. 3,4 engaging portion 3B is formed on each of the bottom causes the crowned to both guards 3,4 thumb portion and four finger outer side of the upper 1, ground base 2 bottom of the engaging portion 3B In this case, the upper part 1 and the protective members 3 and 4 are bonded with an adhesive between them.

The protective bodies 3 and 4 of this embodiment are shown in FIGS.
As shown in the figure, the main body 3A has a shape corresponding to the external shape of the thumb, and an engagement portion 3B for engaging with the ground bottom recess 2A is provided on the bottom surface. The engaging portion 3B is provided at the rear of the bottom surface as shown in the figure, but may be provided at the central portion or at both. The engaging portion 3B shown in FIGS. 4 and 5 is formed of a single or double rod-like member extending on both sides. This is advantageous in that deformation can be prevented when pressure is applied from above.

The protective bodies 3 and 4 of the present invention are made of leather such as cowhide impregnated with steel plate, reinforced plastic, or synthetic resin.
These are shaped into a shape corresponding to the outer shape of the thumb or four fingers and used. When the engaging portion 3B is provided, the corresponding piece or bar can be welded, riveted, or integrally formed. At this time, the height of the protective bodies 3, 4
If the bottom surface is made substantially equal to the bottom surface of the grounding bottom when bonded, it is convenient because the toe can be protected while maintaining its original shape when pressure is applied from above.

In the example shown in FIG. 2, the cushioning sheet 5 is interposed between the front cloth 1A and the back cloth 1B at the positions corresponding to the toes on which the protective body of the upper 1 is covered. Such a buffer sheet 5
In addition to helping toe protection, the upper 1 can be provided with a certain tension when the protective body is covered, which is convenient for manufacturing. Note that such a buffer sheet 5 may be interposed by, for example, bonding to the inner surface of the upper cloth or the inner surface of the back cloth of the upper 1.

[0016]

Since the present invention has the above-mentioned structure, the thumb and the four fingers can be moved separately, while providing a protective body at the toe, so that the movement of both fingers can be achieved. There is no restriction, so that the feeling of lightness is not impaired, and the protective body is firmly attached to the upper with the bonding and the engagement of the engaging portion, so that the protective body comes off during use and comes off. Therefore, there is an advantage that it is possible to reliably protect the toe portion for a long period of time and to provide a basement which is easy to manufacture due to its configuration.
