Abstract: A door security device for enhancing structural integrity between a door and a doorjamb includes a generally U-shaped door reinforcing member, a reinforced striker plate, and securing members. The door security device may be installed on a door including a door latching device and having a bolt member selectably movable within the doorjamb to secure the door to the doorjamb when the door is closed. A cut-out within the end plate of the door reinforcing member has at least a selected vertical height, and the reinforcing member and striker plate are mounted to the door and doorjamb, respectively, such that the striker plate is received within the cut-out when the door is closed without the latching plate overlapping the end plate of the door reinforcing member. Since the edge of the door is closely adjacent the doorjamb and striker plate, the door reinforcing member may be stamped from relatively thick stock having a substantially uniform thickness, thereby reducing manufacturing costs.

Abstract: In accordance with illustrative embodiments of the present invention, a door lock for a rear door of a van includes a T-shaped member having a leg that is received in the opening between the door hinges, and arms that extend outward from the leg over a portion of the door and the body, respectively. The leg is padlocked against removal from the opening.

Abstract: A door locking device for preventing an opening of a hinged door. The locking device of the present invention includes a door jamb restraint independent of the conventional striker plate and secured to a door facing surface of the door jamb. In one embodiment, a main plate is provided independent of the door handle for engagement with the door jamb restraint. The main plate includes a central plate portion in engagement with the door jamb restraint, a first wing fixed on one side of the central plate portion for engagement with the interior room wall, and a second wing portion fixed on the opposing side of the central plate portion for engagement with the door, thereby preventing rotation of the main plate with respect to the door jamb restraint and thus preventing opening of the door. The device of the present invention is relatively inexpensive and does not operate in conjunction with the door handle or a conventional door jamb striker plate for increased versatility and ease of installation.
