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.

[0003] Such a basement is required to be lightly attached and to be in close contact with the feet in order to improve the feeling of contact with the ground.
Even in the S standard, the dimensions are finely determined according to the size.

[0004] Table 1 and Fig. 4 show the dimensions of each basement specified in this JIS. For example, in the case of a size of 25.0 mm, the length AB is 250 mm and the width of the fitting portion is 9
5mm, heel width 62mm, depth 44m
m, and the front and rear sizes are changed every 6 mm in length, and the depth is changed every 1 mm.

[0005] As described above, when the basement is close to the foot, it feels light and feels good on the ground. When she fell, her toes were susceptible to impact and damage, leaving problems in protecting her toes.

[0006] For such protection, a protective body made of a steel plate or the like is interposed in the upper part of the toe of the basement, or is covered with the outer part of the upper part.
This is already known from Japanese Patent Publication No. Hei. 3-32241.

[0007] 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 latter case of 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.

In addition, when the protective body is attached in this way, the protective body is made of a steel plate firmly, so the hardness is inevitably high, and in every underground where the protective body is made to adhere to the foot, The protective body always hit the fingertips and toes through the upper, which sometimes hurt this area.

[0010]

SUMMARY OF THE INVENTION In view of the above situation, the present invention does not damage the fingertips and toes even in underground places where a protective body is attached to the toe, and the equipment of the protective body. It is intended to provide a basement that does not impair the original wearability and lightness by making the shape as little as possible.

[0011]

That is, the gist of the present invention is that, in each basement in which the grounding bottom is attached to the upper, each is separately shaped to cover the thumb and the four fingers. In addition, the base of the shell has a shape that follows the upper, and the thumb and four-finger protectors that protrude outward from the fingertip to the toe by the size of the discarded part are outside the thumb and four fingers of the upper. Each basement is characterized in that the base of the protective body is adhered to the upper part so as to form a gap from the finger head to the toe part.

[0012]

According to the present invention, since a gap that is discarded is provided in a portion corresponding to a finger head and a toe, the presence of the gap while maintaining the original dimensions of the basement makes it possible to wear The fingertips and toes do not strike the protective body with high hardness, preventing damage from the inside as much as possible.Moreover, the thumb and the four fingers move separately, There is no loss of lightness. It should be noted that the discarded dimension is an extra portion of the original underground dimension, and is used in this sense.

FIG. 1 shows an example of the underground of the present invention, and FIG. 2 is an enlarged sectional view taken along the line AA 'of FIG. In addition,
The protector shown in FIG. 2 is a thumb protector, but the four-finger protector is also substantially the same, though slightly different in shape, and is not shown in a sectional view.

In these figures, reference numeral 1 denotes an upper, and the upper 1 comprises a front cloth, a back cloth, and an insole,
These are sewn with fabric. 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 ground bottom 2 has an uneven surface generally called a tread pattern.

The present invention provides a thumb protector 3 formed in such a shape of the toe of each basement in a shape corresponding to the outer shape of the thumb, and a separate shape from the thumb protector 3 in a shape corresponding to the outer shape of the four fingers. The shaped four-finger protection body 4 is covered and adhered to the outside of the thumb and the four-finger, respectively. And these two protective bodies 3,
As for 4, the base 3A on the side of the shell has a shape following the upper 1 and is formed so as to bulge outward 3B from the fingertip to the toe by the size of the discard.

FIG. 2 shows a cross section of the thumb protector 3 used in the present invention, and the protectors 3 and 4 including the same are made of a steel plate, a synthetic resin such as reinforced plastic, or a cow leather impregnated with a synthetic resin. The leather is shaped and used.

The protective bodies 3, 4 thus formed are
Is covered with the thumb and the four fingers of the upper 1 and is adhered so that a gap 3C is formed from the thumb to the toe. Since the base 3A has a shape along with the upper 1, it is adhered to this portion. It can be bonded with an agent interposed.

As a result, a gap 3C is formed from the finger head of the finger 5 to the tip of the toe, but a crotch is formed between the thumb and the four fingers in the basement, and the above-described original depth "
Is limited, the forward movement of the finger is restricted, and this part does not move forward and hit the protective bodies 3 and 4 without any damage, and does not damage the inside. The depth of the void 3C, which is a discarded size, may be set to such a size that the finger head and the toe are not impacted when colliding with another object, for example, about 2 to several mm.

FIG. 3 shows another embodiment of the present invention.
In this case, the thumb protector 3 is provided at its lower end with a mounting seat 3D that is bent inward .
As shown in the figure, a cutout is provided at a position corresponding to the mounting seat on the bottom surface . Then, the base 3A of the protective body 3 is bonded to the upper 1 and the mounting seat 3D is provided.
Is fixed in the notch step, and the fixing pin 6 is fixed here with the mounting pin 6 interposed therebetween. By doing so, the thumb protection body 3 can be more firmly fixed. The mounting pin 6 can be embedded in the grounding floor 2 in advance, inserted into a hole provided in the mounting seat 3D, and fixed by caulking the tip of the pin.

In the embodiment shown in FIG.
Is omitted, and the mounting seat 3D is housed in the notch step,
During this time, it can be fixed with an adhesive

If the height of the protective members 3 and 4 is set so that the bottom surface of the protective members 3 and 4 is substantially equal to the bottom surface of the grounding bottom, the original shape of the toe portion is maintained when pressure is applied from above. It is convenient because it can be protected.

[0022]

As described above, the present invention has the above-mentioned structure. Since a gap portion which is discarded is provided in a portion corresponding to a finger head and a toe portion, the finger head and the toe portion are worn during wearing. The part does not hit the protective body with high hardness, preventing damage from the inside as much as possible.Moreover, the thumb and four fingers move separately, and the protective body also minimizes contact with equipment. It has the advantage that it does not impair the lightness of the underground.
