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. When the cooperating striker pin is brought back into proximity with the rotating lock lever as the toolbox is being closed, the force of the striker pin rotates the rotating lock lever back to the trap position, and a biasing spring returns the rotating link member back into engagement with the lock lever to prevent the lock lever from releasing the striker pin.
