Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a leg device for a relatively heavy frame such as a so-called furniture-style kotatsu.

(B) Prior Art A conventional structure with bendable legs fixed to a frame body is disclosed in, for example, Japanese Utility Model Publication No. 50-44400.

However, such bending mechanisms usually use thick metal plates to provide strength, but the edges of these metal plates are exposed to the outside and there is a risk of burns if touched by feet or hands. Ta.

For this reason, it has been proposed to cover the bending mechanism with a resin cover, but when the legs are bent, the space between the cover and the bending part is exposed, resulting in poor appearance. If the kotatsu was placed against a wall, the above-mentioned space would become even more visible from the outside, making it unsuitable for a so-called furniture-style kotatsu, which is based on a luxurious feel. Furthermore, the space mentioned above was uncomfortable, with spider webs and trash infiltrating.

(c) Problems to be Solved by the Invention The present invention has a leg body configured to be bendable by an upper hinge body and a lower hinge body, which prevents dirt from entering the upper hinge cover and improves the appearance. It has a better appearance.

(d) Means for Solving the Problems The present invention provides a frame body in which an inner rail and an outer motor are combined and the ends of adjacent outer motors are fixed by a leg mounting bracket, and a frame body that is fixed to the leg mounting bracket and can be bent freely.
