Abstract: A base plate with an extension which defines a pair of notched seats is secured to the frame of a pivoting door in the gap between the frame and the door. A stop plate, made from a disk of stiff metal plate having an aperture of predetermined shape and with three bent sections that form a hand grip, is initially placed over the extension on the base plate while the door is closed. The stop plate aperture allows the stop plate to be displaced horizontally and downwardly until the section of stop plate defining the opposite end of the aperture lies within the upper notched seat and rests on the base plate. The stop plate confronts the face plane of the door; the door is prevented from opening beyond the door frame by the combination of the stop plate and the base plate.

Abstract: A portable auxiliary locking device for use with a door hung in a door jamb having a latch hole for receiving a horizontally extendible latch bolt. The locking device includes a plate thin enough to fit in the gap between the door and the doorjamb and long enough to extend inside the door and the doorjamb when the door is closed. The plate has at least one vertical slot and a tongue extending transversely from one end of the plate dimensioned to fit within the latch hole. A cross plate slides into a slot in the plate until a notch on the bottom edge of the cross plate engages the plate and locks the position of the cross plate. The cross plate includes an off-centered threaded aperture to accept a bolt. The bolt is adapted to be threaded through the aperture until it makes firm contact with the door or doorjamb.

Abstract: The sliding windows in the back of the cab of a pick-up truck are vulnerable to break-ins because a thief can pry the panes apart using friction from the pressure of his hand on the panes. The normal clamp is by-passed during this type of break-in. An adjustable-length strut is formed with hook-shaped ends. The hook-ends engage around the outer edges of the sliding panes. A catch on the strut comprises a peg which is spring-loaded into engagement with a notch. When the driver presses the peg, he thereby disengages the catch on the strut, allowing the strut to be set to the length where the hook ends can be engaged to and disengaged from the edges of the panes.

Abstract: A portable door lock comprises a planar lock plate for extending from a door frame and a door edge with a transverse tongue at one end that passes through a frame striker plate into a recess. Apertures in a central portion of the lock plate align with apertures in a block that slides on the lock plate. A locking pin extends through registered apertures in the block and lock plate to lock the block relative to the lock plate when the block is slid against the door.

Abstract: A portable auxiliary door lock includes a lock cylinder slidable upon a bar having toothed edges to engage the locking means within the cylinder. The device differs from such locks for sliding panels, as it provides for temporary attachment between the edge of an arcuately hinged door and the adjacent door jamb to secure the door when it is closed. One end of the bar is bent at a 90 degree angle to insert into the latch recess of the striker plate. However, rather than using the lock cylinder to abut against the door and thereby at least partially blocking access to the lock cylinder for actuation due to the adjacent door knob assembly, the cylinder faces away from the knob assembly and an additional stop plate is used to retain the door. Other improvements are provided, such as adjustment for the spacing between the door and the jamb and additional security to preclude the forced removal of the lock cylinder from the bar.

Abstract: A security device for preventing the opening of a hinged door surrounded by a door frame and a door jamb.
