The disclosed concept pertains generally to electrical switching apparatus, such as circuit breakers, and more particularly, to enclosures for electrical switching apparatus and the components of the enclosures, such as latching doors and latching mechanisms.

A compact door barricade apparatus for use on doors is described. The apparatus is equipped with a protective inner case, outer case, door mount, an upper barricade, a lower barricade, barricade pivot links, handles, and barricade latches. Screws or lag bolts are used to mount the barricade latches to the door frame. The door mount connects the apparatus to the door. The barricade pivot links effectively link the movement of the upper barricade to that of the lower barricade. The movement of the handle disposed on the apparatus facilitates the synchronous movement of the upper and lower barricades across the width of the door and door frame, effectively securing individuals within a room.

A door of a substrate container includes a latching mechanism for operating at least two latch members. The substrate container can be a front opening substrate container or a bottom opening substrate container. The latching mechanism can include a rotatable cam having a first rotational profile out of phase with a second rotational profile such that when the cam is rotated to operate the latch mechanism from the disengaged position to the engaged position, a first latch member engages a first corresponding slot in a door frame prior to a second latch member engaging a second corresponding opening provided in the door frame such that the latch members are operated in a staggered manner. This staggered latching configuration allows for the application of a load provided by the system to be used in the most efficient manner per latch arm or per set of latch arms.

A door apparatus, including a first lintel, including a first slideable bolt, and a first rotatable cogged wheel, being interlaced with the first slideable bolt, and a door, including a second bolt being slideable by key operation, to interlace the first rotatable cogged wheel to rotate thereof, thereby to slide the first slideable bolt, and a first depression, for housing the first slideable bolt of the first lintel, thereby locking thereof to the door, thereby massive locking allows reducing the second bolt of the door.

An emergency escape apparatus includes a support frame that is configured to be installed on a door or a wall and that defines an exit opening, an escape door that is located at an inner side of the exit opening and configured to open and close the exit opening and that defines an accommodation space, a driving unit located in the accommodation space and configured to rotate relative to the escape door, and an unlocking device that is located in the accommodation space, that is configured to be pushed by the driving unit, and that is configured to release coupling between the escape door and the support frame based on rotation of the driving unit. The driving unit is configured to be controlled by a control unit based on a sensor detecting an event.

Described herein is a pre-mounted lock assembly for a door of a low and medium voltage electrical cabinet including a containment profile that develops along a main direction defining a seat. A mechanism is arranged in said seat. Said mechanism includes at least a rod and at least one guide element for said rod. Said guide element is rigidly connected to said profile. The pre-mounted lock assembly also includes fixing means for fixing it to said door following the connection of said at least one guide element to said profile, wherein said fixing means are arranged on said profile and/or on said at least one guide element.

An attack, ballistic and blast resistant door that includes integral concealed mortised four bolt-strike locking assemblies where the bolts are retracted with one hand operation for opening the door and are automatically extended for locking the door with closure of the door. The door has a door frame with four adjustable concealed striker receivers within the door frame. The door has four interconnected concealed mortised bolt lock assemblies, each with a biased bolt, wherein one of the bolt lock assemblies has an engageable brake to hold all four interconnected biased bolts in retraction when the door is opened after a handle interconnected with the four biased blots is moved to a door open position. A roller assembly is provided in the one bolt lock assembly biased to extend and move out from the door when the door is opened and releases the brake and allows the biased bolts to extend and move into the strike receivers when the extended roller assembly is moved inwardly toward the door. A manually adjustable ramp is on a strike plate cover over the strike receiver opposite of the one bolt lock assembly with the engageable brake. The ramp adjustably engages the roller assembly to further move away from or toward the door to adjustably release the brake.
