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.

The invention relates to a cabin for transporting passengers, comprising at least one door (P1, P2), an interior floor (C) and a doorsill (S) located on either side of the door, and a locking device comprising a lug (E) which is rigidly connected to the door and projects toward the outside of the cabin, and a catch finger (4) that is movable between a locked position and an unlocked position. The invention also relates to an actuating mechanism comprising a pedal (7) which is located under the interior floor (C) of the cabin and can be accessed via a hatch in the floor of the cabin, and a kinematic connection between the pedal (7) and the finger (4), which connection is located under the interior floor (C) and under the doorsill (S) of the cabin. In the locked position, the finger is an abutment on the path of the lug (E). In the unlocked position, the finger is retracted under the doorsill (S) of the cabin.

A locking mechanism for securing a computing device in an enclosure includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever. When the arm is coupled to the transmission lever, opening the arm causes the transmission lever to rotate open about the actuating pivot. Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.
