In order to optimize the functioning of the rotary-latch lock, the invention proposes to provide a release member (24) which by means of the rotary latch (6), as the latter rotates into the open position, releases the actuating member (19) for the catch (9) for return displacement into the starting position.

Abstract: A toolbox latch is disclosed having a pivoting handle mounted to a housing and mechanically linked to a pusher arm for setting in motion a series of linkages to trap and release a cooperating striker pin. The pusher arm rotates a swiveling trip lever when a turn-key member is first rotated into an unlocked position and the handle pulled in a pivoting motion away from the housing. The swiveling trip lever in turn rotates a rotating link member out of its locking position with a rotating lock lever, allowing a biasing spring on the rotating lock lever to rotate out of its trap position. The cooperating striker pin is thus freed from the trap position as the rotating link member disengages with the rotating lock lever and the latch is open.
