Abstract (en)
A channel latch having a lock for holding the latch bolt closed which includes a secondary locking feature that prevents the lock from being turned. The lock mechanism has a tumbler barrel (15) with a central reciprocal plunger (10) that has a key (9) portion which outwardly projects through the barrel into a keyway (25) in the bolt (2). The plunger (10) is depressed downward against a spring(11) when a tool is inserted into the tumbler to turn it. The keyway (25) includes longitudinal grooves (21, 23) and a pathway that restrict the upward release of the plunger (10) only when the tumbler is turned to either the locked or unlocked position. Once the plunger (10) is released the key and groove abutment prevents the lock from being turned.
