Abstract
A closure latch includes a latch frame pivotally mounting a latch bolt and a cam member. A common torsion spring interconnects the bolt and cam member for biasing the bolt to unlatched position and biasing the cam member oppositely of the bolt. The cam member is normally located against the spring bias by engagement with the latch frame, and a cam surface of the cam member engages a leg of the bolt to maintain the bolt in latched position. When the cam member is rotated oppositely of the spring bias, the cam surface of the cam member moves past the leg of the bolt so that the spring rotates the bolt to unlatched position. The spring returns the cam member to its normal position in engagement with the latch frame and locates a shoulder of the cam member adjacent the leg of the bolt. When the bolt moves from unlatched to latched position, the leg of the bolt engages the shoulder of the cam member to rotate the cam member against the bias of the spring until the bolt leg has moved past the shoulder whereupon the spring returns the cam member to its normal position wherein it blocks movement of the bolt to unlatched position by engagement with the bolt leg.
