    Abstract: A multi-point lock for a closure includes two or more of a latch (19,20), lift bolt (13) and at least one drive element (16,17) for operating a shoot bolt or remote deadbolt. A drive cam (15), a drive gear (14) and a toothed member (42) coupled to at least one of said lift bolt (13) and at least one said drive element (16,17), said toothed member (42) being in meshed engagement with the drive gear (14), said drive cam (15) being drivingly coupled with the drive gear (14) via a lost motion coupling (38,40). Rotation of the drive cam (15) in one direction can thus actuate the latch (19,20) and in the opposite direction actuate the drive gear (14) to cause movement of the lift bolt (13) and drive element (16,17).
