A door arrangement contains a door for a room with a door leaf, a wall portion of a wall structure laterally adjacent to the door, and a locking arrangement for the door. The locking arrangement includes a locking device in the door leaf with a blocking element, which can be moved in and contrary to a blocking direction in order to block or release the door, and a lock actuator in the wall portion with a first mechanical actuating element, which is unconnected to the blocking element in order to shift the blocking element, by mechanical contact pressure, from the movement position into the blocking position and vice versa. A control and information system contains the door arrangement, a control device for the lock actuator, a human/machine interface, and a communication interface for an authorized body different from the user.

A safety gate includes a first column, disposed on a first side of an elevator shaft, a second column, disposed on a second side of the elevator shaft, a first gate panel, and a second gate panel. The first gate panel is coupled to the first column via a first locking hinge. The second gate panel is coupled to the second column via a second locking hinge.

The door viewport with cross-door locking bar laterally spans the door frame with a viewport exterior lip on the door and an interior face plate near an interior of the door forming, in one instance, a mid-bar capture channel. Alternatively, the viewport has an interior extension coacting with a complementary interlocking element on the cross-bar's midpoint. Either construct holds the cross-door locking bar substantially at its mid-point. Cross-bar terminal end mounts removably attach the cross-bar to the door frame. One type of mount is an L-bracket. Another type of mount is a controllable transverse extension member forcing a door frame plate against the door frame. A user-controlled extension means forces the cross-door locking bar away from the door frame plate, with either a screw drive system or a grooved rod with spring loaded lever control.

Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

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.

A door locking assembly for locking a door from the inside includes a brace that has a pair of slots each integrated therein such that a respective one of the slots can be positioned on a neck of a doorknob. The brace is longitudinally elongated to extend between a door on which the doorknob is positioned and an adjacent door jamb. A pair of fingers is each coupled to and extends away from the brace. Each of the fingers extends along a line oriented perpendicular to the brace. In this way each of the fingers extends between the door and the door jamb thereby inhibiting the brace from spinning downwardly on the doorknob.

A sliding door brace apparatus for creating a strong seal on a sliding glass door includes a fixed clamp having a receiving channel to receive an outer frame of a sliding door and a set screw extending into the receiving channel. An extension arm is coupled to the fixed clamp. A rail has a proximal end coupled to the extension arm and a distal end. A slider is coupled to the rail and a trigger is coupled to the slider to ratchet the slider towards the distal end of the rail. A release button is coupled to the slider to allow the slider to move towards the proximal end of the rail. A door wedge is coupled to the slider to engage a panel frame of the sliding door.

A device for placing in a sliding door or sliding window frame that adds additional security to prevent a sliding door or sliding window from being opened. The device is a secure locking device which comprises of a main bar and a lever bar that are connected to each other such that lever bar may pivot where it is connected to the main bar. The main bar is adjustable such that a length may be adjusted to allow the secure locking device to fit within varied sizes of sliding door/window frames. The secure locking device is also comprised of a locking mechanism that is controlled by a lever actuator and a lock button which are configured onto the main bar. The secure locking device is easily accessible by a user to lock and unlock in order to secure and unsecure the sliding door. The secure locking device is easy to position in a track of the sliding panel and does not require any need to secure into place.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when activated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A portal defined by a ballistic door viewer or viewport is located in the panel and permits viewing or observing through the panel. A release system is configured to deactivate the stop and enable the device to move.

A device for securing sliding windows and doors includes a telescoping bar and a plate. An end of the bar and the plate together form a connector pair that couples the bar end to the plate in one of a separable orientation and an inseparable orientation according to a relative angle between the bar end and the plate. The connector pair allows the bar to be separated from the plate in the separable orientation when the relative angle is a first angle, and the connector pair prevents the bar end being separated from the plate in the inseparable orientation when the relative angle is a second angle. A lock in the locked position physically prevents the relative angle between the bar end and the plate being changed from the second angle to the first angle. A T-bar or side-wing may prevent unlocking when the window or door is open.
