ABSTRACT:
A lock for use with a door having a latch which is adapted to be received in a notch located in the door frame can be utilized either as a permanently-installed lock or as a portable lock that can easily be moved to various locations. A planar member is adapted to be disposed between the door frame and the door when the latter is in closed position. A laterally extending tab is disposed at a right angle to the planar member and is adapted to be received in the notch. A pair of slots in the member are mirror images of each other and diverge away from a divider element that lies in a horizontal plane passing through the tab. Each slot is configured to present a plurality of seats for receiving a keeper pin adjacent the door, when the latter is closed, to present a dead bolt lock. By simply turning the member 180.degree. the lock can accommodate either a left or right-hand opening door with the opposite slot being utilized for each position of the member. A housing is normally disposed in the notch of a door frame and is permanently secured to the frame by a pair of fasteners. The planar member has a pair of arms which are adapted to be disposed on either side of the notch and by removing the housing and inserting the fasteners through appropriate openings in the aforementioned arms, the lock apparatus may be permanently mounted on the door frame.
