Abstract
A door lock for door structures such as used in buildings includes a U-shaped clamp member having an elongated hook portion adjustably supported longitudinally on one leg thereof. An angle plate with a hook receiving right is secured by screws to the door. The U-shaped clamp member is positioned about three sides of an upright post that forms part of the frame of the door structure so that the hook member projects laterally outwardly from the fourth side of the upright post for engagement with the hook receiving right. With the hook and ring engaged, the locking member is movable downwardly into biting engagement with the post to positively secure and hold the door against the door frame.
