Retractable latch bolt assemblies for upgrading locks
Spring-projected latch bolt assemblies each having a retractable latch bolt component are used to upgrade commercially available lock operating mechanisms so that closures carrying the upgraded lock operating mechanisms can lock automatically when the closures reach their fully closed positions. To permit unobstructed closing of each closure, a normally extended component of each associated spring-projected latch bolt assembly retracts during a final segment of the closing of an associated closure, and snaps back to its fully extended position as the associated closure comes to rest in its fully closed position.
