The width, height and interval 4 of the rising pieces 3 are freely set to correspond to the function of each part so that the rising pieces 3 protect the edge of the upper 1 and support the wearer in a firm standing position, and that the intervals 4 among the rising pieces maintain flexibility and air permeability.

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 Underground shoes are manufactured by attaching an upper obtained by stitching cloth and a grounding bottom made of rubber or synthetic resin to each other by sticking or stitching. The lower part of the upper, that is, the contact part with the grounded bottom of the upper, was liable to come into contact with the object, rubbed, or subjected to a concentrated load to be damaged.

For this reason, conventionally, in the sewn type, cloth is sewn as a reinforcing piece to this portion, and in the pasted type, a rubber tape having substantially the same width is attached around the peripheral edge of the contact portion. .

[0004]

However, although the former sewn piece of reinforcing fabric does not affect the flexibility, the reinforcing effect is insufficient, and the latter one with the rubber tape attached is heavy. However, the rubber tape on the bent portion may peel off during walking.

The present invention newly develops a reinforcing piece continuously connected to the grounding bottom without using a conventional reinforcing cloth piece or rubber tape, and thus is resistant to abrasion and has excellent flexibility and breathability, and the foot It is intended to provide a basement that can be kept firm against movements and loads.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a large number of parallel connection by being connected to a grounding bottom at a portion extending over at least substantially the entire side portion of the upper contact portion of each underground. The rubber or synthetic resin standing piece is fixed to form an underground piece.

It is even more preferable that the upright piece is continuously fixed to substantially the entire side portion and the heel portion, and can also be fixed to substantially the entire circumference including the toe portion.

In the standing piece, the standing piece in a portion which is easily worn or damaged is formed densely, or formed higher than other portions, or formed thicker, or in a composite mode thereof. If formed, it can be made more durable against wear and more sturdier to foot movements and loads, and can be made underground.

[0009]

The standing piece protects the contact portion, and at the same time, the standing piece supports the movement of the foot and the support against the load, and the gap between the plurality of juxtaposed standing pieces maintains flexibility and breathability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the underground of the present invention, the ground 1 made of rubber or synthetic resin is fixed to the upper 1 sewn with cloth by a sewing method by sewing or a sticking method by adhesion,
At the same time, a standing piece 3 made of rubber or synthetic resin is fixed to the contact portion of the upper 1 (the lower part of the upper close to the grounding bottom) and is connected to the grounding bottom 2 in parallel and fixed.

The upright piece 3 is a rod-shaped or band-like body integrally formed upright from the peripheral portion of the ground contact bottom 2, and has a proper gap 4,
For example, the standing pieces 3 are arranged side by side around the width or with a gap narrower than this. As an example of the width of the standing piece 3, 2 to 1
The height is preferably around 0 mm and the height is around 15 to 45 mm, and the gap 4 is preferably around 1 mm to 10 mm.

Further, the standing piece 3 may be a flat body having an inner surface bonded to the upper 1, but its cross-sectional shape is semicircular, trapezoidal, triangular, in order to increase abrasion or shear resistance. It is preferable to form a square shape or a part of the flat outer surface into the above shape or the like, and to make the tip end a rounded surface or an obliquely inclined surface from the tip of the inner bonding surface toward the outer surface in order to prevent catching. Alternatively, the outer surface may be a rough surface such as a textured surface.

The upright piece 3 can be formed over the entire circumference of the contacting portion, or can be formed over substantially the entire circumference except for the toe portion. Is preferable from the viewpoint of effect, but it may be formed almost entirely on the side.

It is preferable that the standing piece 3 is formed with the grounding bottom 2 in a slightly outwardly inclined shape in which the tip gradually expands toward the tip at the time of molding, but it may be formed to extend in a substantially horizontal shape. It is possible and is fixedly integrated with the upper 1 by an adhesive.

Furthermore, it is more preferable that the standing piece 3 is formed as in the following embodiments. The embodiment shown in FIG.
The standing pieces 3 are arranged side by side over the entire side part and heel part.
The upright pieces 3 are generally of the same width and the same height and are susceptible to wear, for example, on the thumb side, the fingers, the thighs, and the heel, and on the four fingers, the fingers and the treads on the heel. An example is shown in which they are densely arranged to enhance the reinforcing effect, and other portions are roughly arranged.

In FIG. 3, the upright pieces 3 are formed with the same height and the same clearance as a whole, while the width is increased at a portion susceptible to wear to enhance the reinforcing effect, and the other portions have a width narrower than this. The formed example is shown.

In FIG. 4, the standing pieces 3 are formed with the same width and the same clearance as a whole, while they are formed higher (longer) in a portion susceptible to wear to enhance the reinforcing effect and lower in other portions ( (Short) is shown.

Although not shown, the upright pieces 3 can be formed by appropriately combining the density, the thickness, and the height of the upright pieces 3, if desired. For example, in the vicinity of the base of the finger, it is necessary to maintain flexibility as well as reinforcement, so do not increase the width,
The tall standing pieces 3 should be arranged densely, or the tall standing pieces 3 should be arranged densely with an appropriate thickness. Or the thick standing pieces 3 may be densely arranged. In any of the above examples, it is preferable that the shape of the standing piece 3 and the gap 4 between the site susceptible to wear and the other site are formed so as to gradually change.

The bottom surface of the ground contact bottom 2 may be formed in a substantially flat shape, or may be recessed in the vicinity of the tread portion to form, for example, a middle-high arch shape, and the recessed portion may be formed in comparison with other portions. Alternatively, a high hardness material may be blended to form a hard material, or a double bottom may be formed, and the construction of these bottoms is arbitrary.

[0020]

As described above, according to the present invention, the standing pieces that are integrally arranged in parallel with each other from the grounding bottom substantially all over the circumference enhance the effect of reinforcing wear resistance and shear resistance, and the standing pieces themselves. The presence of the gap between the standing pieces arranged in parallel with each other makes it possible to enhance the bending property, and to enhance the grounding property and maintain the air permeability, resulting in comfortable wearing and in any movement direction. It is possible to provide an underground territory with a firm grounding and a ground contacting property that follows movements such as bending and twisting. Moreover, by appropriately combining the width, height, gap width, etc. of the upright pieces, the desired effect described above and the design effect of the upper peripheral side portion can be exhibited at the same time.
