Description

[Detailed Description of the Invention] The present invention relates to a cover structure at the leg end of a chair, table, etc.

That is, a nut is fixed to the lower surface of the tip side of each leg frame extending in the horizontal direction, and the leg end of a chair, table, etc., which is constructed by screwing the adjuster star of the caster to the nut, can be used to prevent people's feet, shoes, etc. Alternatively, a cover can be attached to provide cushioning in the event of a collision with a wall or between a desk and a chair.It can be easily attached to the end of the legs, and it can be fitted well with the cover attached. It is an object of the present invention to provide a device that can be attached so as not to come off, and can also provide a sufficient buffering effect, so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the chair, with the seat 10 shown above.
At the lower part of the support leg 12 having a back body 11, each leg frame 1 extending horizontally in four directions is provided in series, and a square nut 2 is fixed to the lower surface 1a of the tip side of each leg frame 1. The adjuster star 4 extending above the caster 3 is installed by screwing into the nut 2, and is constructed in the same manner as the conventional structure.

A shows the entire cover, which is made of rubber and has a bag shape so as to cover the entire circumference of the tip side of each leg frame 1, but the tip portion 5, which is the bottom side of the bag, is made thick,
A raised portion 13 is formed in a bulging shape around the entire lateral periphery excluding the opening side, and a concave portion with a low step into which the nut 2 can be fitted is formed on the upper inner surface side of the lower surface portion 6 on the inner back side. 7 is formed, and a hole 8 into which the adjuster star 4 can be fitted is formed through the concave surface portion 7.

Therefore, when the cover body A is inserted and fitted into the tip end of each leg frame 1 from the opening side with the caster 3 removed, the nut 2 of the leg frame 1 falls into the concave part 7 and the 8, the adjuster 4 of the caster 3 is inserted into the hole 8 of the cover body A from below, and the nut 2 is inserted into the hole 8 of the cover body A.
When screwed in fully, the cover body A can be attached and the caster 3 can be mounted as shown in FIGS. 1 and 3.

In this state, even if a person's feet or shoes collide with the wall, or the desk and chair collide, the cover body A will be able to cushion the collision, especially since the cover body A is thick on the tip side. This is effective, and since the nut 2 and the concave portion 7 are fitted together and the adjuster star 4 is inserted into the hole 8, the cover body A is attached so that it does not come off and is fitted to the tip of the leg frame 1. Become.

In this way, the present invention fixes a nut 2 to the bottom surface 1a of the end side of each leg frame 1 extending in the horizontal direction, and screws the adjuster star 4 of the caster 3 onto the nut 2 to create a chair, table, etc. At the leg end of the leg frame 1, a tip portion 5 of a rubber bag-shaped cover body A that can be fitted into the tip side of the leg frame 1 is formed to be at least thick, and above a lower surface portion 6 that is the innermost part of the cover body A. A concave portion 7 into which the nut 2 can be fitted is formed on the inner surface, and the adjuster star 4 is fitted into the concave portion 7.
Since the hole 8 into which the leg frame 1 can be inserted is formed, even if a person's feet or shoes collide with the tip side of the leg frame 1, or a wall or a desk and a chair collide, the cover body A can cushion the collision. In particular, the tip 5 of the cover body A, which has a high possibility of collision, is thick and has a large cushioning effect, and the bag-shaped cover body A, which is made of rubber, can be easily installed by simply fitting it. In addition, in the installed state, the nut 2 is fitted into the concave portion 7 and the adjuster star 4 is fitted into the hole 8, so the cover body A is fitted well to the tip side of the leg frame 1 so as not to come off. It has the feature that it can be carried out suitably.
