Abstract: A lock for a door comprises a casing, a bolt, a pivoted operation handle, operable to retract the bolt, a locking member to deadlock the bolt against retraction, and a unitary spring steel connecting member between the handle and the locking member. The connecting member has a central coil around a rod which acts as a pivot for the locking member and one end of the connecting member is cranked to engage in a recess of the locking member. The other end of the connecting member is shaped such that when engaged by the handle, as the handle is pivoted to retract the bolt, it transmits a force to the end at the locking member to overcome the force of a spring holding the locking member against the bolt, thereby to release the deadlocking and allow bolt retraction.

Abstract: A dead bolt lock assembly for securing a sliding door or window and including a wall mountable dead bolt lock, and a door mountable dead bolt lock which matingly engage in the locked position to secure the sliding door or window shut, is disclosed. The wall mountable dead bolt lock may be moved between an unlocked position and a locked position (where it is received within the housing of the door mounted dead bolt) in an automatic manner by an actuator which is preferably normally biased to extend slightly beyond the door jamb. The actuator may be connected to the dead bolt by a drive assembly which is activated upon movement of the actuator inwardly toward the door jamb, for example by a plunger. In one embodiment, as the actuator moves inwardly, it causes the dead bolt to move outwardly, until it is received within the housing of the door mounted dead bolt. The wall mounted dead bolt includes an aperture at one end for receiving the dead bolt of the door mounted dead bolt therein.

Abstract: A deadbolt extender which automatically extends a deadbolt when the door upon which it is mounted is closed. The deadbolt extender comprises a tongue body reciprocating within a tongue body track, a deadbolt reciprocating within a deadbolt track, and a release mechanism releasably engaged with the tongue body. A tongue attached to the tongue body retractably engages a spring-loaded deadbolt latch. The tongue body track diverges from the deadbolt track, so that when the tongue body is at an extension end of the tongue body track, the tongue is retracted out of the way, and the deadbolt may be operated conventionally, using a conventional deadbolt drive mechanism. The deadbolt extender will not extend the deadbolt automatically upon door closure unless first cocked, thereby eliminating unwanted "lockouts".

The second interlocking meeting rail engages the flexible release member in order to lift the retractable bolt from the slot in the faceplate. A spring forces the bolt outwardly from the latch body to secure the first and second windows together.

Abstract: A door latch assembly for holding a door in a closed position comprises a latch housing for mounting in the side of a door frame, and a latch pin for mounting on the corresponding side of a door to project towards the latch housing. The latch housing has an opening for receiving the latch pin as the door is closed, and a latch member in the housing is movable between a first, latching position in which the latch pin is held in the housing and a second, release position in which the latch pin is released and pushed out of the housing in a door opening direction. An actuator projects out of the housing for moving the latch member into the second position. The latch member is biased towards its latching position.

Abstract: A data cabinet door has a plurality of latch bolts connected by cables to a central actuating plate. When the plate is depressed by a handle to release the bolts it is itself retained in the released position by a lever acting under the bias of a spring, to keep the bolts withdrawn. This lever is connected by a cable to a release plate associated with one of the latches so that when the door is slam-closed the release plate engages an abutment on the cabinet body and pulls the lever to release the plate, which latter springs up once more and permits all the latches to engage.

Abstract: A door stop assembly for vertical insertion in a single hole in a floor in the path of a swinging door includes a tubular housing with a top flanged housing for retaining the assembly in the floor, a tubular door check rod within the flanged housing and spring biased to extend up into the path of the door upon being triggered, and a trigger bar coaxially extending through the door check rod. The top surface of the trigger bar is normally flush with the flange so that the door check cannot be accidentally extended by merely stepping on it. When depressed below the flange surface, a steel ball, normally contained within two aligned radial holes in walls of the door check bar and housing, drops into an annular groove in the trigger bar to thus release the door check bar from its housing. When the door check bar is pushed down, the groove in the trigger bar replaces the ball in the aligned holes to relock the check bar in its housing.
