A casement lock for locking a door, the casement lock having a casement lock housing, an actuation element rotatably mounted on the casement lock housing,. and a locking element which is coupled with the actuation element and can be translationally moved in a first angular range of the actuation element and rotationally moved in a second angular range of the actuation element, the actuation element being axially secured by securing means in the first angular range and being axially released by the securing means in the second angular range.

A locking module (40) for selectively coupling a first component and a second component of a lockable device (20) includes a locking member (42) rotatable between an unlocked position and a locked position and an engagement member (50) associated with said locking member (42). Translation of said engagement member (50) drives movement of said locking member (42) between said locked position and said unlocked position to selectively decouple said first component from the second component.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

An unlock mechanism includes a socket, a handle, a driving member, a driving shaft and a moving member. The socket includes a pivot hole. The handle includes a pivot shaft. The pivot shaft is rotatably disposed in the pivot hole. The driving member is movably disposed in the socket and sleeved on the pivot shaft. The driving member includes an inclined surface. The driving shaft is disposed on the pivot shaft and abuts against the inclined surface. The moving member is connected to the driving member. The handle rotates to drive the driving shaft to rotate, the driving shaft pushes the inclined surface to drive the driving member to move, and the driving member drives the moving member to move.

A gate latching system is provided. A gate latching system installed onto a gate hinged to a stationary post for covert, one-handed operation, the gate latching system comprising a latch bar mounted to an interior side of the hinged gate via a plurality of fasteners where a first end of the latch bar rests against the stationary post preventing the gate from opening in an inward direction. The latch bar having a latch affixed next to the first end of the latch bar. An operator lever affixed at a midpoint of the latch bar and a stiff wire connector coupled to the latch and the operator lever and a latch coupling fastened to the stationary post in plane with the latch to optionally couple with the latch.
