ABSTRACT:
A door lock assembly comprising an anchor plate or other anchor means on the floor of a building spaced apart from a door with which the door lock assembly is to be used and in the direction which the door opens, and an elongated locking bar one end of which engages and is secured by the anchor plate or other anchor means, the other end of which abuts against the bottom edge of the door when in closed position to prevent it from being opened until the locking bar is removed from such position. The locking bar lies on the floor between the anchor means and the bottom edge of the closed door which makes it more difficult to dislodge by anyone trying to break in. The door may include a socket to receive the abutting end of the locking bar to keep it even more securely in place.
