Multi-point door lock and offset extension bolt assembly

A multi-point lock assembly for a door member mounted to a door frame and moveable between an open configuration and a closed configuration, comprising;

• a central lock assembly having at least one actuator member extending vertically from the central lock assembly, the actuator member moveable along a vertical axis of movement between a first position and second position, wherein the actuator has a receiver extending horizontally therethrough;
• an extension bolt having an elongated body extending along a vertical extension bolt axis, and having a threaded proximal end connected to the actuator member by an adaptor and a distal end opposite the proximal end, said adaptor having a horizontally-extending body portion having a first end of the adaptor located thereon and a vertical portion extending vertically from the body portion and having a second end of the adaptor located thereon, the body portion having a horizontal length extending generally transverse to the extension bolt axis to displace the extension bolt axis a distance away from the actuator axis,
• wherein the adaptor has a projection extending horizontally from the first end and a threaded cavity extending vertically within the second end, wherein the projection is received within the receiver to connect the adaptor to the actuator member, and the threaded cavity threadably receives the proximal end of the extension bolt therein to connect the adaptor to the extension bolt.

A multi-point lock assembly for use with a door mounted within a door frame, wherein the door includes a lock edge and an interior portion spaced from the lock edge and having a channel within the interior portion, the channel extending from adjacent the door frame to a central location on the door, the lock assembly comprising:

• a central lock unit having a housing configured to be mounted within the door proximate the central location such that an edge of the housing is configured to be proximate the lock edge, a movable actuator member having a first portion located within the housing and a second portion extending out of the housing adjacent the housing edge, and an internal mechanism contained within the housing and operably connected to the actuator member to move the actuator member along an axis of movement between an extended position and a retracted position;
• an extension bolt having an elongated body extending along an extension bolt axis, the extension bolt configured to extend through the channel in the door toward the door frame and configured to be movable to engage the door frame;
• and
• an adaptor having a body portion residing between a first end and a second end, the first end of the adaptor directly connected to the second portion of the actuator member, and the second end of the adaptor directly connected to the extension bolt, wherein the body portion has a length extending generally transverse to the extension bolt axis to displace the extension bolt axis a distance away from the actuator axis.
