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 has already been proposed in Japanese Utility Model Laid-Open No. 6-75O1 that a protective body made of steel plate or the like is attached to the upper without damaging the movement of the finger at the toe portion of each underground.

However, since the underground protection with finger protection has a structure in which the protective hard material is attached to the upper by a stretchable wearing article, it is usually said that the protective hard material covers the toes. When working on pipe scaffolding, the protective hard object does not move upward due to elastic fittings according to the movement of the finger, so that it does not hinder the grounding of the toes. It has become.

However, in the case of the above-mentioned basement, the protective hard object surely shifts upward in accordance with the movement of the fingertip. This means that the protective hard object moves when the finger moves during normal walking or the like. Since the object also moves up and down, it not only feels uncomfortable to walk, but also lacks stability, and there is a great risk that it may come into contact with other objects, and there is a problem with safety.

[0006]

SUMMARY OF THE INVENTION In consideration of the above situation, the present invention has been studied by paying attention to stable attachment of a protective body without impairing the original movement of the toes every time underground.
It has been found that it is effective to place the thumb and the four fingers at three places to fix them, and it is an object of the present invention to provide an underground system having excellent performance for achieving the above object.

[0007]

That is, the gist of the present invention is to provide a shape capable of covering the outside of the thumb and the outside of the four fingers of the upper in the underground where the grounding bottom is attached to the upper. The toe protector of (3) is fixedly attached to the upper or the grounded bottom at three places of the outside of the thumb root, the outside of the four fingers and the outside of the center of the four fingers, and is attached every time.

[0008]

According to the present invention, a toe protector having a shape capable of covering the outside of the thumb and the outside of the four fingers is provided at three locations of the outer side of the thumb root, the outer side of the four finger root and the outer side of the center of the four fingers. Since it is fixed, there is no restriction on the movement of the fingers, especially the thumb during wearing, and it does not impair the agility, and it is stably attached to the upper or the grounded bottom, which may interfere with walking or work. Absent.

The embodiment will be described below with reference to the drawings. FIG. 1 shows an embodiment of each underground of the present invention. In the figure, 1 is an upper, 2 is a grounded bottom, and 3 is a toe protector.
Of these, the upper 1 is usually composed of a front cloth, a back cloth and an insole, which are sewn and integrated,
The underground floor is constructed by being fixed to the grounding bottom made of rubber or synthetic resin by a hanging type or a sewing type. The grounding bottom 2 may be provided with a protrusion with an engagement hole used for fixing the toe protector 3 as will be described later, but this is formed integrally when molding the grounding bottom 2. Good.

According to the present invention, a toe protector 3 having a shape capable of covering the outside of the thumb and the outside of the four fingers is attached to the toe of each basement. Part, the outer part of the base of the four fingers, and the outer part of the center of the four fingers.

The toe protector 3 of this example is shown in FIGS.
As shown in, the main body 3A has a shape capable of covering the outside of the thumb and the outside of the four fingers, and the outside of the thumb base,
Engaging projections 3B, 3C, and 3D that stand up inward are provided inside the bottom surfaces of the four-finger root outer side portion and the four-finger substantially central outer side portion, respectively. Reference numeral 3E in the drawing denotes a folded-back portion provided on the front side of the main body. When this portion is provided, it is convenient for the tip of the grounding bottom 2 to be accommodated. Of these, FIG. 4 shows the engaging projection 3B on the outer side of the base of the thumb, and FIG. 5 shows the engaging projection 3D on the outer side of the center of the four fingers. The engagement protrusion 3C on the outer side of the four-finger base is omitted because it is shown substantially symmetrically with FIG.

The toe protector 3 of the present invention uses leather such as cowhide impregnated with steel plate, reinforced plastic and synthetic resin,
These are shaped and used to cover the outside of the thumb and the outside of the four fingers. Engaging protrusions 3B, 3C and 3D
The corresponding pieces can be welded, riveted or integrally formed.

The toe protector 3 is shown in FIGS. 6 and 7, for example.
It is attached to the upper 1 as described above. That is, FIG.
7 shows the fixed state of the outer side of the thumb base, and FIG. 7 shows the fixed state of the outer side of the center of the four fingers. Aperture 2
A protrusion 2A with B is provided, and protrusions 3B and 3D provided on the toe protector 3 are engaged with and fixed to the engagement hole 2B. Although not shown in these figures, as in the case of FIG. 4, at the outside of the four-finger base of the toe protector 3,
The engagement protrusion 3C is fixed to the protrusion 2A with the engagement hole 2B in a state substantially symmetrical to that of FIG.

When the toe protector 3 is fixedly attached to the grounding bottom 2 as described above, the movement of the finger is not restricted, and the toe can be stably attached at three positions. Particularly in this example, since the projection 2A with the engaging hole is integrally formed on the grounding bottom 2 and the toe protector 3 is fixed by this, the moderate elasticity of rubber or soft synthetic resin is utilized. It can be fixed, which is convenient.

In this case, since an upward pulling force is applied to the projection 2A with the engaging hole, it is preferable to reinforce this portion. For example, as shown in FIG. 12, this is a metal with a hole. This is achieved by attaching the plate 2C to the projecting piece 2A.

Further, as shown in FIG. 12, the projecting piece 2A with an engaging hole is provided.

In this example, a long hole 3F is provided in the fixing position of the protective body 3, and a brim of a metal plate 2D having an L-shaped cross section adhered to the protruding piece 2A is fitted therein. By doing so, since it can move in the vertical direction of the arrow, it exerts a cushioning force and thus the protrusion 2A.
Can reduce the force applied to.

The fixing means of the toe protector 3 is not limited to this example, and a mounting tool corresponding to a projecting piece with an engaging hole may be provided at a corresponding position of the upper 1.

FIGS. 8 to 11 show another embodiment of the present invention, in which the toe protector 3 is fixed as described above, and is further fixed and attached to the upper 1 at the central position of the upper side. Is. In this example, the armor protector 4 and the ankle protector 5
Are connected to each other, and the tip of the belt 4A fixed to the armor protection body 4 is fixed to the toe protection body 3 by the stopper 4B.
It is fixed at the center of the upper side. This protection body 4 is attached to the grounding bottom 2 in the same manner as in FIG. 6 by the belt 4C fixed to the side.
It is attached by engaging with the protruding piece 2A with an engaging hole provided on the.
The ankle protector 5 is fixed to the ankle by a belt 5A. This example has the advantage that not only the toes but also the limbs and ankles can be protected at the same time, but it is more convenient if the muscular protection body 4 and the ankle protection body 5 are detachable.

When the toe protector 3 is fixed to the upper 1 at the center of the upper side thereof as described above, the toe protector 3 can be attached more stably without restricting the movement of the finger. The means for fixing the toe protector 3 at the center of the upper side thereof is not limited to this example. For example, the other end of the belt 4A in FIG.
It may be fixed by snapping it on.
