A door security assembly for blockading a door in a lockdown situation includes a blockade device. An element of the blockade device insertable into a gap defined by a door and a crash bar that is engaged to the door. Each of a pair of fasteners engaged to the blockade device is selectively engageable the crash bar, so that the blockade device is reversibly engaged to the crash bar with the element positioned in the gap. The blockade device prevents actuation of the crash bar so that the door cannot be opened. The fasteners are positioned so that two hands are required to simultaneously disengage the fasteners from the crash bar to enable disengagement of the blockade device from the crash bar.

Provided are a latch mechanism and an electronic device case. The latch mechanism includes a base assembly, a pressing assembly and a first elastic member. The base assembly has an accommodating cavity, and a wall surface of the base assembly has a first through hole and a second through hole which are respectively communicated with the accommodating cavity. The pressing assembly includes a main body part, a button part and a bolt part, the main body part is disposed in the accommodating cavity, and the button part and the bolt part are respectively disposed on the main body part. The first elastic member is located in the accommodating cavity, one end of the first elastic member abuts against an inner wall of the accommodating cavity and the other end abuts against the main body part.

Latch assemblies to secure a door, drawer, or other enclosure are disclosed. An assembly may include a latch and a catch. A latch arm is bendable to transition between an engaging position and a disengaged position. The latch may include a curved flexible support to provide a desired resistance to bending of the latch arm, and the flexible support may be vertically separated from the latch arm. The latch may be made of a unitary piece.

The disclosure relates to a pivot bar for a tiltable sash window where the pivot bar is designed for mounting along an exterior surface of a sash frame. The pivot bar includes a first leg positioned within a channel formed on the stile of the sash frame and a second leg positioned within a channel formed on the bottom rail of the sash frame. In a coupled configuration, the pivot bar wraps around the exterior surface of the corner of the sash frame where the stiles and bottom rail meet.

A safety latch mechanism for anchoring an open center gate in a livestock trailer includes a spring-biased post attached to the center gate's free edge having a lifting lever at an upper end. An arcuate track embedded within the truck bed traces the path of the center gate's free edge when moving between a fully opened and a fully closed position. The track includes a series of juxtaposed, segregated compartments for receiving a lower end of the post. Accordingly, the center gate can be locked in a multitude of angular positions between the fully open and fully closed positions by lifting the lever and releasing it into one of the compartments.
