Multi-point lock having a shootbolt with a flat driverail mounted in a narrow groove

摘要

A multi-point lock having an easy to install modular drive mechanism for shootbolts located at the top and bottom edges of a door in which the multi-point locking system is installed that requires only relatively simple door preparation. The shootbolt operating mechanism is installed into a narrow groove cut into a lateral edge of a door which may be cut using relatively simple tools in relatively quick fashion. The shootbolt actuating mechanisms are flat driverails that are made of flat barstock that fit slidably entirely within the narrow groove defined in the lateral edge of the door above and below the mortise pocket.

主权项

1. A multi-point lock comprising:
at least one shootbolt assembly comprising a shootbolt slidably located in a shootbolt housing for mounting in one of a top and bottom edge of a door, wherein the shootbolt housing is installed into an aperture positioned on one of the top edge and the bottom edge of the door; at least one driverail having proximal and distal opposite ends, said driverail configured for installation into a narrow groove defined in a lateral edge of the door; the aperture is adjacent to and in communication with the narrow groove, wherein the width or diameter of the aperture is larger than the width or diameter of the narrow groove; the driverail being installed in said narrow groove in a vertically slidable manner, the narrow groove configured to guide and retain the driverail in the door throughout the driverail motion, said distal end of said driverail being engageable with said shootbolt to drive said shootbolt between a retracted position in the shootbolt housing and an extended position from one of the top edge and the bottom edge of the door; a notch defined in said driverail adjacent said proximal end thereof, the notch opening in a direction extending out of the narrow groove when the driverail is installed in the narrow groove; and a mortise unit adapted for installation into the lateral edge of the door through the narrow groove, said mortise unit having a driving element associated therewith that is moveable between unlocked and locked positions, said driving element extending into the notch defined in said driverail when said mortise unit is installed into the lateral edge of the door through the narrow groove after said driverail has been installed into said narrow groove to place the driving element in operative engagement with the driverail; wherein said shootbolt is driven from said retracted position to said extended position when said driving element of said mortise unit is moved from said unlocked position to said locked position.
