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 ). |
