Abstract: A metallic interior security device for double doors comprising a plate of sufficient length to extend beyond adjacent door knobs of the double doors. Formed in the plate are longitudinally spaced slots. The slots are elongated in the longitudinal direction of the plate and are disposed along the plate to receive the neck or narrow portions of the adjacent door knobs, respectively. The width of the elongated slots is greater than the diameter of the neck portions of the door knobs to accommodate the neck portions thereof simultaneously, and is of a lesser diameter than the diameter of the enlarged portions of the door knobs to prevent the removal of the door knobs from locking engagement with the plate.

Abstract: A hinged unit that serves as a security door step to prevent opening of a slidable door. The unit consists of a pair of bars pivotably linked together at adjoining ends and of a length to fit in the extended position, between an external bottom side edge of a slidable door and the bottom side edge of the door frame within the bottom channel in which the door slides to block movement of the door in the closed door position. The hinge line is located below the horizontal longitudinal axis of the joined bars in the extended position. A pivoted kicker plate is pivoted to one bar so that downward pressure on the kicker plate serves to raise the hinge point above the horizontal axis so that the bars will fold upward about the hinge point to permit the bars to fold against the door frame along a vertical axis as the door is opened.

Abstract: A hidden or concealed lock for sliding windows, door panels and the like, employing a concealed hollow tubular locking sleeve that is positioned entirely inside of an aligned opening passing through the interior frame of one of said windows and into the frame of the other window. The locking sleeve is manipulated into and out of locking position by a small rod shaped key member that is coaxially insertable into the locking sleeve from outside the window after passing through the small opening in the window frame. Both the locking and key members and openings are made small and unobstrusive; and are located for concealment in differing locations. These features prevent an unauthorized user from either locating the lock, determining its mode of operation; or unlocking the windows or panels without access to the special key.

Abstract: An anti-vandalism lock device particularly adaptable for panic-type doors includes a substantially C-shaped housing having a substantially vertically disposed threaded bolt secured therein. The housing is adapted to be mounted upon one of the pivotable lever arms supporting the panic bar and connected with the panic door latching mechanism in such a manner that an end wall of the housing abuts one side surface of the lever arm while upper and lower laterally projecting sections of the housing similarly engage the upper and lower surfaces of the arm, and the threaded bolt is secured within the housing in such a manner as to engage the opposite side surface of the lever arm thereby fixedly securing the device upon the panic-bar assembly and positively preventing actuation of the door latching mechanism.

Abstract: A compact portable lock has a locking plunger angled to fit into a pre-drilled opening in a door or window rail permitting a lock with very minimal clearance requirements with regard to the adjacent frame. A window in the bottom cover plate of the lock accommodates a flange on the lock plunger and defines the travel of the plunger.

Abstract: This invention pertains to a portable security lock having a sliding fastener and chain that loops around the doorknob stem and a hook that connects to the striker plate and the chain so that when the door is closed, the lock cannot be jimmied or removed unless the portable security lock is removed.

Abstract: A clamping device especially adapted to detachably and easily clamp plate-like members such as corrugated cardboard. The clamping device comprises two clamping members with a U-shaped channel for receiving therein the plate-like members to be clamped, a flexible member interconnecting the two clamping members, and an intermediate member formed integrally with the two clamping members and adapted to be placed between the two clamping members to extend the flexible interconnecting member to the locking position. The above members are formed integrally by forming suitable flexible plastic. When the clamping device is inserted into the clamping holes formed through the plate-like members to be clamped, it is bent along the flexible interconnecting member in such a way that the U-shaped channels of the clamping members receive therein the plate-like members.

Abstract: The present invention is directed to a lock detachably engaged in a hole in the frame of a sliding window or door with an element on the lock engaging against the window or door to prevent the window or door from being slid from its closed position toward an open position. The lock includes a double lead thread for fast action. An arm on the lock for engagement with the window can be positioned in either of two vertically spaced reduced diameter portions on the lock shaft.

Abstract: A one-piece clip is provided for temporarily locking a cabinet door in a closed position. The clip is fabricated from a stiff, resilient material such as metal or plastic, wire or ribbon and is formed with a pair of reversing relatively deep U-shaped bends. The free end of one bend is shorter than the free end of the other bend and is also shorter than the cross-piece of the other bend whereby the clip, when mounted over the door jamb of the cabinet, is capable of limited lateral movement to allow the door first to swing clear for opening and installation and to be locked by laterally shifting the clip so that the outer U-shaped end engages the edge of the door in the closed position. The clip may be used for keeping the door shut during shipment of newly assembled cabinets, for example.

Abstract: A guard to prevent unauthorized opening of sliding doors and similar closures, comprising a longitudinal member having a major portion and a minor portion hinged together end-to-end. The guard when fully extended, is positioned normal to the direction of opening of the door, and extends between the jamb and the edge of the door and preferably resting on the floor. When the door is to be partially opened for ventilation, the minor portion is hinged 180.degree. so as to overlap the major portion. The resultant shortened guard then permits the door to be opened only an amount equal to the length of the minor portion.

Abstract: A device for securing a lid or cover upon an out-of-doors garbage can, so to prevent a wind from blowing the cover away or refuse collection men from leaving the covers scattered about, instead of replacing them upon the can, after a refuse collection; the device in a preferred design of the invention consisting of a heavy nylon strap secured at one end to the cover handle and which at its other end is secured to a handle on a side of the garbage can.

Abstract: A sliding panel lock for locking sliding panels such as windows or patio doors slidably coupled to a frame in which the top edge of the frame is captured within an inverted U-shaped channel consisting of a wedge member having a top edge dimensioned for abutting the top inside surface of the channel and a clamp member for clamping the wedge member in position, the wedge member having an inclined bottom surface for wedging against the corner of the sliding panel and extending between the top surface of the sliding panel frame and the bottom surface of the channel into which the frame of the panel member is received, thereby preventing the sliding of the panel toward the wedge member and the lifting of the panel out of the bottom channel.
