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.

For this reason, it has already been proposed in Japanese Utility Model Laid-Open No. 6-7501 to attach a protective body made of a steel plate or the like to the upper part of a toe under the basement without impairing the movement of the finger.

[0004] However, this underground part with finger protection has a structure in which a hard protective material is attached to the upper with an elastic mounting article, so that the hard protective material usually covers the toe. When working on a pipe scaffold, the protective hard object is displaced upward by elastic wearing equipment according to the movement of the finger, so that it does not interfere with the grounding of the toe. It has become.

[0005] However, in the case of the above-mentioned basement, the protective hard object is certainly displaced upward according to the movement of the fingertip. The object also moves up and down, causing not only a feeling of discomfort in walking but also a lack of stability, and furthermore, there is a great possibility that it will come into contact with other objects, and there is still a problem in safety.

[0006]

SUMMARY OF THE INVENTION In view of the above situation, the present invention has been studied by focusing on the fact that the original toe movement is not impaired every time underground and the protective body is stably mounted.
It is effective to fix at the three places of thumb and two fingers and to fix the upper part at the center of the upper side, and to provide an underground base having excellent performance to achieve the above object. It is.

[0007]

SUMMARY OF THE INVENTION 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 each basement where the ground is attached to the upper. The toe protector is fixed to the upper or ground bottom at the outer part of the base with the thumb, the outer part of the base with the four fingers, and the outer part of the center of the four fingers, and is fixed to the upper at the position of the center of the upper side of the toe protector. There is a basement each time it is installed.

[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 places: the outer side of the base with the thumb, the outer side of the base with the four fingers, and the substantially outer side of the center of the four fingers. Because it is fixed to the upper at the center of the upper side, there is no restriction on the movement of fingers, especially the thumb during wear, so that it does not impair lightness, and it is stable on the upper and the ground floor It is attached and does not hinder walking and work.

A description will be given below with reference to the drawings of an embodiment. The drawings show an embodiment of the present invention for each underground, in which 1 is an upper, 2 is a grounding bottom, and 3 is a toe protector.
The upper 1 of these usually consists of a top cloth, a back cloth and an insole, which are sewn and integrated,
The basement is fixed to the grounding bottom made of rubber or synthetic resin by a hanging type or a sewing type. The grounding bottom 2 can be provided with a protruding piece with an engagement hole used for fixing the toe protection body 3 as described later. 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. In addition, it is intended to be fixed at three places, ie, the outer part of the base, the outer part of the base of the four fingers, and the substantially outer part of the center of the four fingers, and to be fixed to the upper at the center of the upper side.

FIGS. 4 to 7 show the toe protector 3 of this embodiment.
As shown in the figure, the main body 3A has a shape capable of covering the outside of the thumb and the outside of the four fingers,
Inwardly protruding engagement projections 3B, 3C, and 3D are provided inside the bottom surfaces of the four-finger root outer part and the four-finger substantially central outer part, respectively. In the figure, reference numeral 3E denotes a folded portion provided at the front of the main body, and if this portion is provided, it is convenient to fit the tip of the grounding bottom 2. 6 shows the engagement projection 3B on the outer side of the base of the thumb, and FIG. 7 shows the engagement projection 3D on the outer side of the center of the four fingers. Note that the engagement projection 3C on the outer side of the four-fingered root is not shown because it is substantially symmetrical with FIG.

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

The toe protector 3 is, for example, shown in FIGS.
Is attached to the upper 1 as follows. That is, FIG.
9 shows the fixed state of the outer side of the base with the thumb and FIG. 9 shows the fixed state of the outer side of the center of the four fingers. Hole 2
A protruding piece 2A with B is provided, and the projections 3B and 3D provided on the toe protection body 3 are engaged with the engagement holes 2B and fixed. In addition, although not shown in these figures, as in the case of FIG.
The engagement protrusion 3C is fixed to the protrusion 2A with the engagement hole 2B in a state substantially symmetrical to FIG.

When the toe protector 3 is attached to the grounding bottom 2 by being fixed as described above, the movement of the finger can be stably attached at three places without restriction on the movement of the finger. In particular, in this example, since the protruding piece 2A with the engaging hole is integrally formed on the grounding bottom 2 and the toe protection body 3 is fixed by this, the appropriate elasticity of rubber or a soft synthetic resin is used. It is convenient to fix.

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

Also, as shown in FIG.
FIG. 12 shows an example in which the resin is further fixed by using a buffering action in the case of reinforcing. In this example, a long hole 3F is provided at a position where the protective body 3 is fixed, and a flange of a metal plate 2D having an L-shaped cross section attached to the protruding piece 2A is fitted therein. In this way, the protrusion 2A can be moved in the vertical direction of the arrow, so that the protrusion
Can be reduced.

The means for fixing the toe protector 3 is not limited to this example. For example, a fixture corresponding to a projection with an engagement hole may be provided at a position corresponding to the upper 1.

According to the present invention, the toe protector 3 is fixed as described above, and the upper
It is attached to the horn. In this example, the shell protector 4 and the ankle protector 5 are connected, and the tip of the belt 4A fixed to the shell protector 4 is fixed at the center of the upper side of the toe protector 3 by the stopper 4B. doing. The armor protector 4 is engaged with a protrusion 2A with an engaging hole provided on the grounding bottom 2 in the same manner as in FIG. Note that the ankle protection body 5 is fixed to the ankle by a belt 5A. According to this example, there is an advantage that not only the toe portion but also the shell and ankle can be protected at the same time. However, it is more convenient if the shell protector 4 and the ankle protector 5 are detachable.

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

[0020]

As described above, the present invention has the above-mentioned structure, and while the protective body is provided at the toe, there is no restriction on the movement of the fingers, especially the thumbs, during wear, and the light feeling can be impaired. And it is stably mounted on the upper and the ground bottom, and does not hinder walking or work.In addition, due to its configuration, the toe protector can be attached and detached, etc. There are advantages.
