Abstract:
1. A lock assembly having an arm coupled to a latch for selectively locking and unlocking a door using a key, said assembly comprising: a housing having threads for mounting said housing to the door in a mortise configuration and said housing defining a plurality of blind holes for mounting said housing to the door in a rim configuration; a first actuator coupled to said housing for engaging the arm to retract the latch to unlock the door with said first actuator utilized in said mortise configuration; a second actuator coupled to said housing independently from said first actuator for engaging the arm to retract the latch to unlock the door with said second actuator utilized in said rim configuration; a core removably disposed in said housing, said core comprising one of a first core and a second core each removably disposed in said housing such that said first core is interchangeable and replaceable with said second core and said cores having a keyway defining a slot for receiving the key, said keyway and said slot being rotatable within respective cores between a locked position and an unlocked position; and a universal drive member rotatably fixed to said housing independently of said first and second actuators with said keyway of said cores selectively coupled to said universal drive member such that said first core is interchangeable with said second core and removable from said housing independently of said universal drive member with said first and second actuators independently removable from said universal drive member with said keyway and said universal drive member movable together between said locked and unlocked positions when coupled together and said universal drive member interchangeably receives said first and second actuators while one of said first and second cores remain coupled to said universal drive member for interchanging said mortise and rim configurations.
