Abstract: A locking system wherein the latch is rotatable to provide either a first beveled surface for use as a ramp in latching or a second beveled surface for use as a ramp in unlatching. An entire latch module may be rotated about its axis by a rotary solenoid to achieve this function, and the first and second ramping surfaces are physically the same surface repositioned by rotation 180°. Alternatively, a releasable latch has a beveled surface for engaging a striker plate during bolt entry and a non-beveled surface for locking. The latch is pivotable to allow the non-beveled surface to become the beveled ramp for unlocking. The releasably pivotable latch mechanism may be used with a deadlock. The mechanism is readily incorporated into a rim exit device for releasably securing a door such as an emergency exit and may be actuated either electrically or manually.

Abstract: A locking/unlocking mechanism for an operable cover of a body such as a printer to lock and unlock the body with a single operation and to a printer having an operable cover and a locking/unlocking mechanism for the operable cover. The operable cover is locked when a cover side engaging part in the cover engages a body-side engaging part in the body. The printer has a cover opening button 10 which is depressed to a first operating position 10B, causing a locking lever 14 in the locking/unlocking mechanism 11 to slide from a locked position 14A to an unlocked position 14B.

Abstract: A lock for a door comprising a casing, a bolt operable to extend from or retract into the casing and manually operable bolt retention means to retain the bolt in its retracted state even when an automatically operating bolt holding member is released by inwards movement of a bolt release member. The bolt retention means comprises a snib having a part receivable in an opening in the bolt when the bolt is manually moved into the case from its normally retracted position. Once the snib part is in the opening and the inwards force on the bolt removed, the spring acting on the bolt moves the bolt to its normally retracted position, where it is then retained by the snib. To release the retention, the bolt is again moved further into the case, whereupon the snib part is moved clear of the bolt opening under spring bias, and the unretained bolt is moved by its bias to its normally retracted position.

Abstract: A cabinet earthquake latch assembly designed to be attached on a cabinet inner surface and a back surface of a cabinet door. The cabinet earthquake latch assembly includes a door arm, a cam and a strike. When in use, the door arm is attached to the cabinet door, the cam is rotatably attached to the door arm and the strike is attached to the cabinet inner surface. The cam and strike are configured and attached to the door arm and cabinet inner surface such that the cam collides with the strike when the cabinet door is being initially opened at at least a predetermined speed (e.g., a speed generated in an earthquake). This collision causes the cam to rotate from a rest position and then to become lodged against the strike in a rotated position, thus preventing further opening of the cabinet door.

Abstract: A shutter assembly for an intake opening in an exhaust fan for improving heating and cooling efficiency of a structure by preventing air in the structure from flowing through the exhaust fan and out of the structure. The shutter assembly for an intake opening in an exhaust fan includes a door for selectively positioning over an air intake opening in an exhaust fan. The door is mountable on the surface round the exhaust fan by at least one hinge member. The hinge member may be mounted on the door for pivotally coupling the door to the surface around the exhaust fan such that the door is pivotable between an open position and a closed position. A locking assembly is mounted on the surface and releasably couplable to the door for selectively securing the door in the closed position.

Abstract: The locking bolt of a swing bolt lock has an elongated opening that fits on a shaft in the lock's housing. The shaft has a compression spring that biases the bolt toward one side of the shaft. In normal operation, the compression spring urges the bolt such that the shaft is at one end of the elongated opening. There, the swing bolt pivots about the shaft to unlock the lock. When a person tries to force the lock, the elongated opening of the bolt moves against spring bias along the shaft. In one embodiment, flat surfaces in the opening and on the shaft engage each other and a notch on the outside surface of the bolt engages a stationary safety key. This prevents the bolt from applying sufficient force to break weaker parts within the lock mechanism and force the lock open.

Abstract: A cabinet earthquake latch assembly designed to be attached on a cabinet inner surface and a back surface of a cabinet door, thereby making it invisible from outside of the cabinet. The cabinet earthquake latch assembly can be operated with one hand and is functional with a wide variety of cabinet configurations. The cabinet earthquake latch assembly includes a door arm, a cam and a strike. When in use, the door arm is attached to the cabinet door, the cam is rotatably attached to the door arm and the strike is attached to the cabinet inner surface. The cam and strike are configured and attached to the door arm and cabinet inner surface such that the cam collides with the strike when the cabinet door is being initially opened at at least a predetermined speed (e.g., a speed generated in an earthquake). This collision causes the cam to rotate from a rest position and then to become lodged against the strike in a rotated position, thus preventing further opening of the cabinet door.

Abstract: A lock for a door (10) comprising a casing (11), a bolt (55) operable to extend from or retract into the casing and manually operable bolt retention means to retain the bolt in its retracted state even when an automatically operating bolt holding member (74) is released by inwards movement of a bolt release member (69). The bolt retention means comprises a snib (106) having a part receivable in an opening (103) in the bolt (55) when the bolt is manually moved into the case from its normally retracted position. Once the snib part is in the opening and the inwards force on the bolt removed, the spring acting on the bolt moves the bolt to its normally retracted position, where it is then retained by the snib. To release the retention, the bolt is again moved further into the case, whereupon the snib part is moved clear of the bolt opening under spring bias, and the unretained bolt is moved by its bias to its normally retracted position.

Abstract: A window fastener having a mounting base (21), a latching flap (12) moveably coupled thereto, a handle (14) and a latching tongue (15). the handle (14) is movable between first and second positions and is coupled to the latching tongue (15) so that the latching tongue moves the latching flap (18) when the handle (14) moves to a latching position. A movement inducing mechanism (34, 41) operable by the handle (14) causes movement of the flap (12) to occur when the handle is moved from the latching position to a non-latching position.

Abstract: A latching mechanism selectively maintains a first member and a second member in secured engagement by the interposition of a striker plate, mounted upon the second member, between spaced apart arms carried by a latching cam mounted on the first member for pivotal movement and locked in a latching position against such movement by a locking member, and moves the first member away from the second member upon selective release of the secured engagement by the actuation of a push-button assembly which unlocks the locking member and allows the latching cam to be moved out of the latching position by a biasing spring so that one of the spaced apart arms pushes against the strike plate to move the first member away from the second member.
