Door lock

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° 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.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is: 
     
       1. Lock apparatus for use with a door having a latch adapted to be received in a notch located in the door frame, said apparatus comprising: a planar member adapted to be disposed between the door and the frame;   structure extending laterally from the planar member and adapted to be received in said notch when said member is placed between the frame and the door,   said member having a pair of slots therein disposed in diverging relationship to a horizontal plane passing through said structure when the latter is received in the notch,   said member including a divider element lying in said horizontal plane for separating said slots one from the other;   each of said slots having at least one edge thereof configured to present a plurality of seats along the edge of the slot; and   keeper means adapted to be received in one of said slots when said member is disposed between the door and the frame with the keeper means received in the seat adjacent the door whereby said keeper means presents a dead bolt lock to preclude opening of the door.   
     
     
       2. The invention of claim 1, wherein said member includes a chamfer generally perpendicular to said horizontal plane at the end of the member opposite said structure, said chamfer presenting a camming surface for the door latch prior to the latter being received in said notch. 
     
     
       3. The invention of claim 2, wherein is included means for permanently mounting said member on said frame with said structure disposed in said notch. 
     
     
       4. The invention of claim 3, wherein each of said slots is a mirror image of the other slot whereby the apparatus can be utilized with either right or left-hand opening doors by rotating said member 180° and placing said keeper means in the opposite slot. 
     
     
       5. The invention of claim 1, said apparatus being adapted for use with a door frame having a housing complemental to said notch and secured by a pair of fasteners passing therethrough, said member comprising: a pair of arms adapted to be disposed on either side of said notch, with an opening in each arm for placement of one of said fasteners, whereby said housing can be removed and replaced with said member mounted on said frame. .Iadd. 6. Lock apparatus for use with a door having a latch adapted to be received in a notch in the door frame, said apparatus comprising:   a planar member adapted to be disposed between the door and the frame;   said member having a pair of slots therein disposed in diverging relationship to a horizontal plane passing through said structure when the latter is disposed between the door and the frame;   said member including a divider element lying in said horizontal plane for separating said slots one from the other;   each of said slots having at least one edge thereof configured to present a plurality of seats along the edge of the slot;   means for mounting said member on said frame; and   keeper means adapted to be received in one of said slots when said member is disposed between the door and the frame with the keeper means received in the seat adjacent the door whereby said keeper means presents a dead bolt lock to preclude opening of the door. .Iaddend..Iadd. 7. The invention of claim 6, wherein each of said slots is a mirror image of the other slot whereby the apparatus can be utilized with either right or left-hand opening doors by rotating said member 180°  and placing said keeper means in the opposite slot. .Iaddend. .Iadd. 8. The invention of claim 6, said apparatus being adapted for use with a door frame having a housing complemental to said notch and secured by a pair of fasteners passing therethrough, said member comprising:   a pair of arms adapted to be disposed on either side of said notch, with an opening in each arm for placement of one of said fasteners, whereby said housing can be removed and replaced with said member mounted on said frame. .Iaddend.
