A door latching system provides an arc resistant door for a power electronics cabinet. The door latching system includes a six point latch to secure the door in place against the frame of the cabinet. The door latching system includes two vertical linkages coupled to a door handle mechanism, the door handle mechanism being able to impart a vertical motion to the vertical linkages as the handle is turned. The latching system allows for this vertical motion to then become horizontal motion for closing several latches between the vertical frame of the cabinet and the door.

A rail for a utility pit includes: a top end; a bottom end distal from the top end; an outer face defining a curved radially outer surface, the radially outer surface configured to mount on an inner surface of the utility pit; an inner face distal from the outer face and defining a radially inner surface; a center-lock strike portion proximate to a first side end of the rail, the center-lock strike portion defining a center-lock strike notch in the bottom surface; and a side-lock strike portion distal from the first side end, the side-lock strike portion defining a side-lock strike notch, the side-lock strike notch defining a central wall and a pair of side walls extending radially inward from the central wall, a surface of each of the pair of side walls angled with respect to the central wall.

A door locking device having a first rotatable handle affixed to a door, a rotatable member affixed to the door, a catch affixed to a surface adjacent the door to receive the rotatable member, and a protrusion from the first rotatable handle configured to lift the rotatable member when the rotatable member is engaged with the catch and the first rotatable handle is rotated.

A device to secure a moveable door, the device having a movable member affixed to the door, the movable member configured to engage a catch, a tab extending from the door, the tab configured to engage a cavity, and a first rotatable handle affixed to the door, rotation of the first rotatable handle retracting the tab so that the tab is no longer engaged with the cavity and moving the movable member so that the movable member is no longer engaged with the catch.

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the application of an activation operation to an activator. A wide range of people having differing physical and mental capabilities may use the barricade-device properly and quickly.

A pit assembly comprises: a pit wall defining an inner surface, and an outer surface; a rail secured to the inner surface of the pit wall, the rail comprising: a top end, a bottom end, a first side end, a second side end, and an outer face defining a curved radially outer surface and mounted on the inner surface of the pit wall; a center-lock strike portion proximate to the first side end; and a side-lock strike portion distal from the first side end, a one of the center-lock strike portion and the side-lock strike portion defining a strike notch in the bottom end; and a lid defining an upper surface and a lower surface and comprising a locking mechanism, the locking mechanism coupled to the lower surface and configured to engage a one of the center-lock strike portion and the side-lock strike portion of the rail.

The automated door-locking device comprises a keypad, a locking bar, and a locking bar catch. The locking bar is of a spring-loaded type. In an embodiment, the automated door-locking device is mounted on a classroom door. The locking bar catch is mounted on the classroom door and the keypad is fastened to the wall of the classroom. The classroom door is allowed to open and close normally when no intruder is on premises. The automated door-locking device is engaged by entering a code using the keypad and setting to Lock Mode. The locking bar is automatically rotated to securely engage with the locking bar catch. The automated door-locking device cannot be breached without breaking down the wall or the door. After the threat is over, the user resets the automated door-locking device to the Safe Mode using the same code. The locking bar releases from the locking bar catch.

A locking device for a container having a hinged lid, comprises a base unit adapted to be fixed to the container and a pivotable unit mounted to the base unit and pivotally movable between on open and closed positions. The base unit includes a base member and a pinion member non-movably attached to the base member. The pivotable unit includes a locking mechanism comprising a pivotable locking member, a sliding member reciprocating between the locking member and the pinion member. The locking member is movable between a blocking position preventing the movement of the sliding member relative the pinion member so as to prevent relative movement between the pivoting unit and the base unit, and a release position permitting the movement of the sliding member relative the pinion member so as to permit relative movement between the pivoting unit and the base unit.

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle on the door. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the use of one or more major muscle groups of the body, but need not require precise dexterity of the fingers or hands (e.g. such as that required to manipulate small keys, latches, and/or the grasping and turning of assemblies). As such, the barricade-device may be used properly and quickly by a wide range of people having differing physical and mental capabilities.

The invention relates to an interactive security and locking system for residential doors, linked to the floor (A), the door (B) and the electrical panel (C) of the dwelling, comprising mechanical means of physical locking, in particular at least one bolt (3), electrical and electronic security means for its opening and closing and means for its management through an application (App) for Android and IOS systems on Smartphone and Smartwatch mobile devices, said App connecting with the closure of security directly (locally) via Bluetooth and GSM and remotely (external server) via Wi-Fi, GPRS and LAN, also implementing means of controlling access to the home, means for connecting auxiliary peripheral elements of security and a security device for opening the door, acting as a self-contained system or as a peripheral unit.

A rail for a utility pit includes: a top end; a bottom end distal from the top end; an outer face defining a curved radially outer surface, the radially outer surface configured to mount on an inner surface of the utility pit; an inner face distal from the outer face and defining a radially inner surface; a center-lock strike portion proximate to a first side end of the rail, the center-lock strike portion defining a center-lock strike notch in the bottom surface; and a side-lock strike portion distal from the first side end, the side-lock strike portion defining a side-lock strike notch, the side-lock strike notch defining a central wall and a pair of side walls extending radially inward from the central wall, a surface of each of the pair of side walls angled with respect to the central wall.
