Abstract:
A mortice lock for recessed installation into the edge of a door or door frame includes a deadlatching member that is mounted on a bolt assembly for pivoting movement. A drive shaft and hub can be rotated in either a clockwise or counterclockwise direction to cause bolt retraction. The drive shaft and hub can be locked against rotation, or not, by a lock that is mechanically connected to a cylinder cam rotated by a key. The drive shaft and hub can be locked against rotation, or not, by a lock that is mechanically connected to an assembly including the bolt assembly interacting with a separately activated kick off member such that on retraction of the bolt, depending on the position of the kick off member, the hub is locked against rotation. The bolt can be retracted by each of the key cylinder cam and the hub, in isolation.
