Patent ID: 8567829

Claim:
A safety device used together with a push-push latch device which latches a movable body to a main body at a fixed position of the main body by a push operation against an urging force of urging means and which allows a latching to be released by a next push operation, the safety device comprising: a circulation cam groove adapted to be provided in either the main body or the movable body and having a reciprocation groove portion, a latching guide groove portion, a returning guide groove portion, a return groove, and a latch groove portion; a responding member adapted to be provided in the other of the main body or the movable body and having a pin provided at one side thereof to trace the circulation cam groove and a balancer at the other side thereof; and an urging member disposed on the responding member to urge the responding member in a pull-in direction; wherein when the responding member receives a load, the responding member slides against an urging force of the urging member and the pin irreversibly moves from the reciprocation groove portion to the latch groove portion through the latching guide groove portion, so that even if the latching of the latch device is released due to the load, the movable body is retained in the fixed position.
