Embodiments described herein are directed to locking mechanisms for security cabinets. In one embodiment, the locking mechanisms for security cabinets provide a visual indication of whether the security cabinet is locked or unlocked. The security containers include a handle assembly that is coupled to the locking mechanism. The handle assembly may be positioned in at least three positions corresponding to the security container being locked and latched; being unlocked and latched; and being unlocked and unlatched. Because the handle assembly is positioned in these plurality of positions that correspond to the lock and latch status of the locking mechanism, indication of the lock and latch status of the locking mechanism may be understood by visual inspection.

Locks for storage containers having closures such as doors, covers or lids are disclosed. The lock is mounted to she closure and is latched in such a manner as to selectively prevent opening or removal of the closure. The latch of the lock can engage a slot in the storage container, a bracket on the storage container, or a strike on the storage container. Alternatively, the latch can engage a mounting bracket on the door or other portion of the door to selectively block movement of a handle for the door. Further, the latch can have a locking device which can selectively block movement of the latch. Movement of the locking device can be selectively controlled by a magnetic key.

An emergency shelter includes a number of reinforced walls that define a substantially enclosed interior space in which people can enter in emergencies; a doorway opening formed in at least one of the walls to permit entry into and exit from the interior space; a door mounted over that doorway opening; and a latching assembly for latching and locking the door in its closed position. The door is configured to slide horizontally relative to the doorway opening between an open position and a closed position so that it can be opened even when debris is blown up against it. The shelter also includes a door jamb adjacent the doorway opening for receiving and partially surrounding a leading edge of the door to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the door does not cave in when struck by debris. A flange on the trailing edge of the door overlaps a flange on the front wall when the door is closed to prevent movement of the door along an axis transverse to the horizontal sliding direction of the door so that the trailing edge of the door does not cave in when struck by debris. The latching assembly securely latches and locks the door in its closed position but permits the door to be opened even when portions of the latching assembly are damaged.

An interlock assembly for a door latch mechanism of a door in a container for bulk material that has an interior lined with a membrane for holding fluid. The interlock assembly includes a plunger in an aperture formed through the door, which moves between an extended position, where the plunger extends into the interior of the container, and a locked position, where the plunger is urged outwardly from of the interior of the container. A spring is positioned to apply a force to urge the plunger to the extended position. A lock member is connected to move with the plunger between the extended position and the locked position. The spring force is selected to enable the membrane, under static pressure of fluid within the container, to urge the plunger to the locked position, thereby engaging the lock member to interlock against operation of the door latch.

A multipoint mortise lock mechanism for a swinging door, including a central cassette assembly operably coupled to an upper remote locking point assembly and a lower remote locking point assembly by a remote locking linkage. The central cassette assembly includes a housing, a deadbolt mechanism, a latchbolt mechanism, a remote locking point mechanism and an anti-slam mechanism. The anti-slam mechanism includes an anti-slam plunger that when in an extended position engages the remote locking linkage via a boss and a slot and thereby inhibits movement of the remote locking linkage whereby deployment of the remote locking point assemblies is prevented. The deadbolt mechanism includes a deadbolt extendible from the central cassette that is independently operable from the remote locking point mechanism. The deadbolt mechanism further includes an anti-back drive mechanism.

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A combination lock is provided, the lock having a latch movably mounted to a housing of the lock for movement between a locked position and an unlocked position; and a bolt movably mounted to the housing of the lock for movement between a first position and a second position, wherein the combination lock is a key-controlled combination changing permutation lock wherein a button disposed away from a rear exterior surface of the housing in a first direction rearwardly away from the rear exterior surface is depressed in order to change the combination of the combination lock and the housing has a button protection feature extending rearwardly away from the rear exterior surface of the housing in the first direction proximate to the button and the button protection feature extends farther away from the rear exterior surface of the housing in the first direction than the button.

The present invention relates to a locking device comprising: a locking bolt (12), a follower arrangement (30) comprising a follower arm (32) configured to rotate about a first axis (B) and also comprising a follower (31) that is configured to rotate about the first axis (B) in response to an activation, a catch arrangement (20) configured to block the follower arm (32) in a blocking state in order to prevent rotation of the follower arm (32), wherein the follower (31) of the follower arrangement (30) is operatively connected to the catch arrangement (20), wherein the blocking state corresponds to the catch arrangement (20) being in an end position of a movement path (P), and wherein the catch arrangement (20) is further configured to operate the follower arm (32) when not in the blocking state so that a movement of the catch arrangement (20) along the movement path (P) causes a corresponding movement of the follower arm (32).

The present invention relates to a locking device 1 having a deadbolt 104 within a casing 102, which deadbolt 104 is movable between an advanced position wherein it protrudes from a front face of the casing 102 and a retreated position, wherein it is retracted into the casing 102. The locking device 1 comprises: a link plate 130 which moves the deadbolt 104 to the advanced position; a deadbolt blocking member 110 which is moveable between a blocking position blocking the deadbolt 104 in the advanced position and an unblocking position to allow the deadbolt 104 to move to the retreated position; an electrically driven actuator unit 120 which moves the deadbolt blocking member 110 between the blocking position and the unblocking position; and a control circuit configured to control the electrically driven actuator unit 120 so that once the deadbolt 104 is moved to the advanced position, the deadbolt blocking member 110 is moved to the blocking position by actuation of the electrically driven actuator unit 120.

Locking device comprising a central body (1) and a handle (2) with movement means (4) which engage a rod (3). Handle is rotatable between an open position and a closed position. In the closed position, FIG. 1 effective anti-effraction means are provided to block movement of the rod. Therefore, movement means (4) comprise a rotor (41) and a single protuberance (42) which engages a seat (312) of a mobile element (31) of the rod (3); Rotation of the handle to the closed position leads to blocking of the mobile element (31) by interaction an edge of the seat (312a) with a head (421) of the protuberance. Thereby, a locking device for windows or doors, such as sliding doors and windows, with burglary-resistant characteristics is provided.
