Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg end structure of a chair mounted on the lower surface of a pipe support leg of a chair for protecting the floor surface.

[0002]

2. Description of the Related Art Conventionally, on the lower surface side of a pipe support leg of a chair,
It is known to wear resin leg ends for floor protection.

[0003]

[Problems to be Solved by the Invention] However, when a chair is moved, dragging noises and impact noises are generated when the leg ends hit the floor surface, which is particularly bad in schools where the floor is P tiles or wooden floors. The problem is that it becomes noise.

[0004]

The present invention solves such a problem and is devised so that the leg ends can effectively slide on the floor surface. Therefore, the pipe supporting leg 1 of the chair B is used. A hole 3 for screwing is formed near one end of the long resin leg end A having a concave curved surface 2 which can be fitted to the lower surface side of the upper part, and a plurality of holes 3 are formed on the upper surface of the concave curved surface 2 side. The recesses 4a, 4b, 4c are formed, and the long square-shaped recess 5 formed on the lower surface of the leg end A extending to one end side which is longer than the hole 3 has a buffer 6 such as a felt at the bottom. It is configured so as to be inserted and exposed below the lower surface of the leg end A.

[0005]

[Effect] Therefore, even if the chair is moved on the floor surface, since the cushioning material such as felt hits the floor surface, dragging noise and impact noise are alleviated and reduced, and the upper surface of the leg end is not affected. Since a plurality of recesses are formed and the lower surface of the leg ends other than the lower surface of the cushioning body also contact the floor surface, even if the chair is dragged, it becomes a cushioning state and protects the floor surface and makes it slide smoothly. be able to.

[0006]

FIG. 6 shows a perspective view of a chair. The chair B is constructed in the same manner as the conventional one by vertically arranging pipe supporting legs 1 and 1 which are bent in a U shape on both lower sides of a seat 7. Yes, both support legs 1,
The leg ends A made of resin are attached to the lower surface of both ends of the lower end portion of 1, respectively. The leg ends A are formed in an elongated shape so that the bottom surface becomes a horizontal plane, and the upper end thereof is fitted to the lower peripheral surface of the pipe. A concave curved surface 2 that can be formed is formed over the entire length in the longitudinal direction, and a hole 3 for screwing that penetrates in the vertical direction from the bottom surface to the concave curved surface 2 is formed at a portion that is deviated to one end side from the intermediate position in the longitudinal direction. 1 is provided on the upper surface on the concave curved surface 2 side between the hole 3 and the one end side.
One recess 4a is formed, and two recesses 4b and 4c are formed on the upper surface of the concave curved surface 2 side between the hole 3 and the other end side, respectively, and the other end side that is longer than the hole 3 is formed. Formed on the lower surface toward the bottom is a recess 4 having a long quadrangular shape having a constant depth, and a buffer 6 such as a felt having a rounded corner and a long quadrangular shape is formed in the recess 5. The lower part is inserted and configured so as to be exposed below the lower surface of the leg end A.

Therefore, even if the chair B is moved on the floor surface, the lower portion of the cushioning body 6 such as a felt hits the floor surface, so that dragging noise and impact noise are alleviated and reduced, and the leg ends are also reduced. The upper surface of A has a plurality of recesses 4a, 4b,
4c is formed, and the lower surface of the leg end A other than the lower lower surface of the cushioning body 6 also contacts the floor surface, so that even if the chair B is dragged, it becomes a cushioning state and the floor surface is smoothly slid. Can be made.

[0008]

As described above, according to the present invention, even if the chair B is moved on the floor surface, the lower portion of the cushioning body 6 such as a felt effectively hits the floor surface, so that dragging noise and impact noise are alleviated. In addition, a plurality of recesses 4a, 4b, 4c are formed on the upper surface side of the leg end A, and the lower surface portion of the leg end A excluding the lower lower surface of the buffer 6 is also on the floor surface. Since it comes into contact with the chair B, even if the chair B is dragged, it will be in a buffered state and will be able to satisfactorily slide while protecting the floor surface, so that it can be used safely as a chair that does not make noise in classes and meetings. It has a feature that it can be suitably implemented with a simple structure.
