Title:
LEG BODY FIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/124541
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a device which makes it possible to fix a leg body to a top plate while maintaining an open-leg state of the leg body, by means of abutment between a cam that pivots in parallel with the leg body and a member corresponding to the follower of the cam. A leg body fixing device 1 of the present invention is provided with: a top plate bracket 100; a leg bracket 200; a hinge shaft 300 which supports the leg bracket 200 pivotally in a hinged manner with respect to the top plate bracket 100; and a lever 400 which pivots in parallel with the leg bracket 200. The lever 400 includes a shaft portion 410 different from the hinge shaft 300, and an operating portion 420 and a cam portion 430 which oppose each other across the shaft portion 410. The cam portion 430 includes a small curvature surface 433. The leg bracket 200 includes a seat portion 230 having a curved receiving surface 231 with a curvature corresponding to that of the small curvature surface 433. When the small curvature surface 433 abuts against the curved receiving surface 231, the cam portion 430 maintains a stationary state and blocks pivoting in a direction in which the leg bracket 200 is closed.
