A refrigerated cabinet may include: a plurality of side walls forming a cabinet body and an interior storage space, the interior storage space accessible through an opening; a first door and a second door independently positionable over the opening; and a mullion formed by the second door, wherein the first door is configured to engage with the mullion. The mullion is a fixed structure formed by a portion of the second door. The refrigerated cabinet may further include a latching mechanism configured to selectively couple the first door and the second door, wherein the latching mechanism extends through the first door to engage the second door. The latching mechanism comprises a user-actuatable interface configured to decouple the first door and the second when the user-actuatable interface is engaged by a user.

An auto-latching latch assembly is mounted to a follower door of a double door. The latch assembly includes a latch movable between an unlatching position and a latching position and a movable member jointly movable with the latch. A positioning member is jointly pivotable with the movable member. When the latch moves to the unlatching position, the positioning member positions the latch in the unlatching position. When the follower door is closed while a primary door of the double door is closed, an actuation latch presses against and releases the positioning member to move the latch to the latching position, reliably locking the follower door.

Self-latching Automatic Flush-bolt for double doors is disclosed. This flush bolt invention eliminates the need for auxiliary coordination devices and allows for the unrestricted movement of each door to maintain security and building code compliance.

A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.

An interlock for an enclosure can include a primary door activator with an activator arm, a secondary door activator, and a rotatable arrangement that links the primary and secondary door activators. The activator arm can block a primary door of the enclosure from being closed when the activator arm is in an open configuration. The activator arm can be configured to rotate with the rotatable arrangement in a first direction towards the open configuration as the primary door is opened, and in a second direction away from the open configuration as the primary door is closed. The secondary door activator can be configured to engage the rotatable arrangement to prevent rotation of the rotatable arrangement when the secondary door is open, and to permit rotation of the rotatable arrangement when the secondary door is closed.

A lock system includes an active panel center gearbox. The active panel center gearbox includes a deadbolt, a deadbolt drive to extend or retract the deadbolt, an upper drive assembly, a lower drive assembly, a latch bolt, a handle assembly to retract the latch bolt and to extend or retract the lower and the upper driver assemblies, a reverse action rocker coupling the lower and the upper drive assemblies so they move in different directions, a mishandling bolt, and a mishandling plate. When the mishandling bolt extends, it lowers the mishandling plate. When the mishandling plate lowers, it engages the deadbolt to prevent the deadbolt from extending, it engages the handle assembly to prevent the lower drive assembly from extending, and it engages the reverse action rocker to prevent the upper drive assembly from extending.

An aircraft panel system including a first panel, having a hinged coupling configured to couple the first panel to an aircraft structure, a second panel disposed adjacent to the first panel such that the first panel and the second panel together form cabin surface of an aircraft, and a latch mechanism configured to releasably couple the second panel to the aircraft structure, where the first panel is configured to pivot about the hinged coupling from a latched position to an actuation position to actuate the latch mechanism and cause a release of the second panel from the latch mechanism.
