Document Type and Number:
Japanese Patent JP2022057825
Kind Code:
A
Abstract:
To improve support stability of a seat while reducing efforts of a manufacturing step in a chair where a leg device is composed of a plurality of rod-like legs.SOLUTION: Respective rod-like legs 1 take inclined postures, outer upper horizontal parts 1b are curved and formed on an upper end 1a, and the respective upper horizontal parts 1b are welded to a base 3 (an upper connection material). The seat 5 is supported by the base 3. As the base 3 is stably supported by the upper horizontal parts 1b, load does not concentrate on a specific site, and a leg device 2 has a strong structure. Welding of the base 3 and the upper horizontal parts 1b is easy, and even when the seat 5 is of a rotary type, the chair can be easily manufactured with high accuracy. When the respective rod-like legs 1 are connected with a footrest ring 8, strength is further improved.SELECTED DRAWING: Figure 2
