Title:
LOCK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/037680
Kind Code:
A1
Abstract:
The present invention comprises a lock shaft (12) attached to a first bracket (3), a lock shaft support shaft (11), and a biasing spring that biases the lock shaft (12) toward a direction coming into contact with a second bracket (4). Rotation progression restricting stoppers (17, 18) are brought into contact with each other, thereby restricting rotation of the first bracket (3) and the second bracket (4) in the locking direction without play. The lock shaft (12) contacts both a first side surface (21) and a second side surface (22), and is set such that a pair of tangents (25, 26) of the lock shaft (12) form a wedge (27), thereby restricting rotation of the first bracket (3) and the second bracket (4) in the direction opposite to the locking direction without play.
