Multipoint door lock system with header and sill lock pins

In a lock system having at least one latch bolt movable normally between an intermediate advanced position for retaining a swinging closure panel in a closed position, and a retracted position for permitting opening of the swinging closure panel, said at least one latch bolt being further extendable from the intermediate advanced position to an extended deadbolt position, the improvement comprising:

• at least one header/sill pin mountable to the swinging closure panel for sliding movement between a normal retracted position and a deadbolt position for engaging an adjacent header/sill keeper to retain the closure panel in a closed position in response to an actuator mechanism that moves said at least one latch bolt between said intermediate advanced position and said extended deadbolt position, whereby said at least one header/sill pin is in said normal retracted position during movement of said at least one latch bolt between said intermediate advanced and retracted positions;
• and
• at least one header/sill cartridge movably supporting said at least one header/sill pin, said header/sill cartridge including a lost motion mechanism for retaining said header/sill pin in said retracted position throughout displacement of said at least one latch bolt between said advanced and retracted positions, said lost motion mechanism being responsive to displacement of said latch bolt between said advanced and said extended deadbolt positions for respectively displacing said header/sill pin between said advanced and said deadbolt positions;
• wherein said lost motion mechanism comprises a driven cam member having a pair of spaced-apart cam faces for engaging a drive link coupled to said header/sill pin, said cam member being shifted back and forth in response to displacement of said latch bolt between said retracted and advanced positions substantially without displacing said drive link, said cam member engaging and displacing said drive link for displacing said header/sill in between said retracted and said deadbolt positions upon respective displacement of said latch bolt between said advanced and said extended deadbolt positions.
