DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground base which can be used in various indoor and outdoor works such as construction work and civil engineering, and has a function of protecting a toe from falling objects.

[0002]

2. Description of the Related Art As shown in FIG. 13, a conventional underground protector 20 having a bottomed semi-cylindrical shape made of a hard metal material is attached to the thumb and the four fingers of the underground. There is known a device in which a heavy object dropped on a toe of a toe is received by a protector 20 to protect the toe. However, in conventional basements, metal protective gears are heavy, making them difficult to wear and work, and require a lot of work to form, making them difficult to commercialize as standard products. Met. For this reason, the present applicant has proposed a basement which can protect the fingertip safely and reliably and can be formed at a low weight and at low cost (Japanese Patent Application Laid-Open No. 8-84601).

As shown in FIG. 14, a protective plate 22 is formed by bending a hard metal plate having an appropriate height into a shape along the outer peripheral side surfaces of the thumb and the four fingers, as shown in FIG. It is fixed to the outer periphery of the upper 23 of the basement 21 in an upright state, and receives a fallen object at the upper end of the protection plate 22 to prevent a fingertip of the toe from being hit directly.

[0004]

The underground shelves 21 shown in FIG. 14 can be formed with a simple structure, light weight and easily, as well as being able to reliably protect their fingertips from falling objects. However, there is a disadvantage in that the protective plate 22 is exposed at the outer peripheral portion of the upper 23, and
When the protection plate 22 is directly attached along the outer surface of the fingertip portion, the protection plate 22 easily hits or presses on the fingertip, and secures a degree of freedom of the fingertip during wearing to improve comfort. To do so, it was necessary to ensure that the fingertips and the guard were separated.

Accordingly, the present invention provides a protective design in which the protective plate is covered with a cover body to prevent the upper end of the protective plate from inadvertently colliding with an object and obstructing a shoe, and at the same time, to provide a characteristic design with good external appearance. An object of the present invention is to provide a basement with good comfort and excellent athletic performance.

[0006]

In order to solve the above-mentioned problems, the underground base of the present invention has a height on the outer periphery of the thumb and the four fingers that can protect the fingertip , and is curved along the outer periphery.
The protection plate formed on the underground is erected from the bottom every time underground, and at least the upper part of this protection plate is engaged with the upper part of the protection plate.
A cover body having a bottom portion is provided. According to this configuration, the fallen object can be reliably received by the protection plate, and the fingertip can be prevented from being directly hit. As the protective plate, any hard material having appropriate rigidity, such as a metal material or plastic, can be used. Since the protective plate is covered with a cover, there is no danger of catching the protective plate on a projection while wearing it, and not damaging it or damaging the fingertips. Can be A plastic or rubber material can be used as the cover. Metal materials such as alloys and thin metal plates can also be used as long as the weight does not significantly increase.

To secure the protective plate and the cover, an engaged portion such as a concave groove is provided at the bottom of the cover, and the upper portion of the protective plate is fitted into and engaged with the engaged portion. By forming a through-hole in the surface and embedding a part of the cover body in the through-hole, the two members can be integrally and firmly connected. The two members may be bonded and fixed via a fixing means such as an adhesive or a rubber paste.

In the basement according to the present invention, a projecting edge is provided on the outer periphery of the thumb and the four fingers at the bottom of the basement, and a projecting protrusion protrudes upward between the projecting edge and the contact portion of the upper. A configuration in which a piece is formed along the outer surface of the fingertip portion, and a protection plate made of a hard material having a height capable of protecting the fingertip portion is provided on the outer periphery of the protruding piece. In order to fix the protection plate to the outer periphery every time underground,
In addition to using an adhesive or the like, a protection plate is erected on the overhanging edge, and with its peripheral surface joined to the outer peripheral surface of the projecting piece,
Both members may be stopped with screws or rivets.

In the above construction, the cover body can be formed into any appropriate shape as long as it covers the protection plate. In addition to having a shape that covers only the upper part of the protection plate, a part or all of the fingertip is covered. Shape.

[0010] In the above structure, it is preferable that a covering piece having an appropriate width is fixed over the cover body and the upper cloth and along the upper edge of the cover body. If the cover piece is fixed so as to straddle the cover body and the upper cloth, the cover body and the upper are integrally joined to eliminate a gap between the members, and dust adheres or accumulates between the two members. In addition, the toe portion can be made to have a clean appearance without unevenness due to a difference in material. As the covering piece, a material having a suitable elasticity or flexibility such as a rubber material, leather, or a plastic sheet can be used.

Further, in the above configuration, it is preferable that a reinforcing piece is fixed to a contact portion of the tread portion with the upper portion. If the reinforcing piece is fixed in this way, this portion is reinforced and the strength against friction and impact increases, and the upper can be given a certain tension to hold the upper in a three-dimensional shape. In combination with this, the toe portion can have a three-dimensional, cleaner appearance. In this case, if the reinforcing piece is fixed to either the inner side or the outer side of the contact portion of the upper, the upper can be shaped to a certain extent, but for the purpose of reinforcing against friction and impact and improving the feeling of wearing. It is preferable that the inner and outer sides of the contact portion are overlapped and fixed. In addition, by firmly fixing the upper and lower contact portions in this manner, the shape retaining force of the upper is increased. For the reinforcing piece, a material having an appropriate hardness capable of giving a certain tension to the upper, and a material having an appropriate flexibility which does not impair the feeling of wearing, more preferably a material having a cushioning property against impact, for example, rubber material, leather, plastic A sheet, or a sheet in which a nonwoven fabric or a foam sheet is used in combination with these sheets can be used.
