A hinge assembly includes a first arm, a second arm, a rotatable pin coupling, and a power transfer conduit. The rotatable pin coupling rotationally couples the second arm to the first arm. The first arm defines a first portion of a channel, the second arm defines a second portion of the channel, and rotatable pin coupling defines a third portion of the channel. The power transfer conduit extends through the first portion of the channel at the first arm, the third portion of the channel at the rotatable pin coupling, and the second portion of the channel at the second arm.

A spindle structure includes a lower rail mounted at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a lower guide rail mounted on the door and configured to form a lower guide route, and a spindle assembly positioned at one end of the lower rail, the spindle assembly including a spindle connected to a fixing unit fixed to the vehicle body, the spindle having one end rollably connected to the lower guide rail, having a threaded portion formed on an outer circumferential surface thereof, and being configured to be movable in a threaded manner between the vehicle body and the door.

The system comprises a lever (2) that is rotatable about a point fixed to the vehicle and articulately joined to the upper edge (6) of the leaf (1); a horizontal guide (3) through which a carriage (4) slides; push-pull means (10,11) that articulately link the upper edge (6) to the carriage (4); and actuation means (12) simultaneously linked to the lever (2) and the carriage (4), which are adapted to distribute their action on the lever (2) and the carriage (4) depending on the force to overcome in order to open and close the leaf (1), such that their action is automatically distributed on the lever (2) when greater power is required to move the carriage (4), this is essentially during the initial opening operation from the end closing position, and during the closing and locking operation from an imminent closing position.

A method for operating a cargo door of an aircraft. The method comprises, opening the cargo door inwardly in relation to a cargo door opening by pivoting the cargo door to an open position adjacent a ceiling of a cargo space. The cargo door is supported by a door frame during opening of the cargo door. The method further comprises, moving the cargo door in relation to the door frame to a position wherein the cargo door opening is substantially free from the cargo door. The cargo door is supported by a support frame, moveable in relation to the door frame, during this movement. The invention also concerns a device for operating a cargo door of an aircraft.

A structure includes a lower rail mounted to a lower portion of a vehicle body in a longitudinal direction of the vehicle body. A lower-rail roller part is rollably connected to the lower rail. A lower-rail swing arm is rotatably connected to the lower-rail roller part and a door. A lower guide rail is mounted to the door and defines a lower guide path in the longitudinal direction of the vehicle body. A lifter has a first end that moves along the lower guide path, and a second end that is fixed to the vehicle body. The lifter applies a force in a direction from the door toward the vehicle body. An upper guide rail is mounted to an upper portion of the vehicle body. An upper-guide roller part is mounted to the door to be seated in the upper guide rail.
