In the case of the above-mentioned conventional basement, a large number of labors are required for forming the protective body 11 and for a process of attaching the protective body 11 to the upper, resulting in poor productivity. In addition, although the fingertip can be reliably protected by the bottomed semi-cylindrical protective body 11, the underground weight becomes heavy, the original light feeling and workability are impaired, and the entire fingertip is covered with a hard material. In addition, a part of the finger hits or is pressed by a hard material, so that the finger is easily damaged, and it is difficult to commercialize as a standard product. On the other hand, if the protection of the fingertip against the falling object is sufficiently performed, it is not necessary to use the protective body 11 formed as described above, and a means capable of protecting the fingertip with a simple structure has been desired.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to secure a fingertip from falling of a heavy object or collision with a mounted object during walking. Another object of the present invention is to provide a basement which can be sufficiently protected, has a simple structure, and is excellent in productivity.

[0005]

In order to solve the above-mentioned problems, the basement of the present invention uses a protective plate having a thickness of about 2 to 6 mm formed by bending a plate having a height capable of protecting the fingertip. It has a configuration in which it is fixed to the outer peripheral side surfaces of the thumb part to the four finger part via a material. It is preferable that a beam plate is arched and fixed between the left and right sides of each of the protection plates of the thumb and the four fingers.

[0006]

[Function] The falling object is received at the upper end of the protection plate attached to the outer periphery of the fingertip of the basement, and the upper surface of the beam plate, and the collision with the mounted object is protected by the wall of the protection plate. Protect your fingertips from the impact from the front. The elastic material serves as a cushion to ease comfort and absorb the impact of a collision with the mounted object, and at the same time strengthens the protection plate.
