The present disclosure is directed generally to automated trailer door systems for use at vehicle loading docks. At least a portion of the trailer door system can be externally driven for opening and closing trailer doors at the loading dock. The automated trailer door system can include a counterbalance shaft that moves the trailer door between a closed position and an open position; and a drive unit having a torsion member operably coupled to the counterbalance shaft; and a drive member rotatably engaged with the torsion member, the drive member having an engagement portion accessible external to the trailer door. Rotation of the drive member via the engagement portion can rotate the torsion member to move the trailer door between the closed and open positions. A door winder can be coupled to a centering body and have a motor to rotate the drive member via the engagement portion.

An automatic door opening apparatus for a vehicle. Two and three hinge joint embodiments with motors at each hinge joint to control motion of the door opening apparatus relative to the vehicle at that hinge joint. The motors are individually programmable to customize the door opening apparatus and movement to different vehicles. The motors can be in alignment or out-of-alignment with the hinge joints, but in either case the motor controls motion of the hinged components at the associated hinge joint. When a motor is out-of-alignment with the hinge joint it controls, then pulley wheels and belts can be used to connect the motor to the hinge joint. The door opening apparatus can also include a floor track, and a door arm that connects the door to the floor track.

Aircraft door (1) including an opening (4), a frame (3), a hinge structure (5) and a circular translation guide device designed to maintain the orientation of the opening (4) during the opening or closing thereof. The hinge structure (5) is connected to the opening (4) by a lifting arm (8) allowing a lifting movement of the opening (4) relative to the hinge structure (5). The circular translation guide device includes a single link (11) connected to the frame (3) by one of the ends thereof and by the other of the ends thereof to a lever (13) which is attached to the hinge structure (5).

A container cabinet has a box-like structure and a door connected to the box-like structure by an articulated quadrilateral. The box-like structure has a first side shoulder and a second side shoulder, an upper panel, a lower panel, and a front part. The articulated quadrilateral, supporting and guiding the door from a door closing position to a door maximum opening position, has a crank having a first crank end and a second crank end, and a rocker arm. The crank is hinged with the first crank end to the door and with the second crank end to the upper or lower panel to rotate about a crank vertical rotation axis. The rocker arm is connected, on one side, to the door and, on an opposite side, to the first side shoulder and has a movable side panel having a movable side panel front end and a movable side panel rear end, respectively hinging the movable side panel to the door and to the first side shoulder.

A door device for the interior of a passenger transport vehicle, and a passenger transport vehicle having at least one door device. The device includes a double-leaf sliding door with a first door leaf and a second door leaf in one plane. The door device has an upper guide for the first door leaf and an upper guide for the second door leaf. The guides are parallel with one another, and at least the upper guide for the first door leaf is offset with respect to the plane of the first and the second door leaf.
