Abstract

A locking mechanism for a garage up-and-over door includes slides (RA5 RA5, RA9) which couple to sliding latch actuating rods (not shown) and are driven via a pin-and-slot mechanism from a plate (RA4) carried on a handle shaft (RA22). A key-driven abutment (26C) acts via lost motion to move a cam (18) between two stable positions defined by a spring (17) to extend or retract a deadlock member (15) coupled to the cam to block or release one of the slides. Due to the lost motion connection the deadlock may be released by direct manual action from inside the door. <IMAGE>
