Abstract
An aircraft door is supported by at least two support rods. Each rod rests with one of its ends in a door hinge that is rotatable with the support rod through an angle of, for example 90.degree., while the door can be shifted up or down along the support rods. For this purpose a torque shaft which is rotatably mounted to the door frame is connected through toggle devices to the other end of the respective support rod, whereby rotation of the torque shaft lifts or lowers the door relative to the support rods. The same torque shaft is connected to the support rods through a linkage device, including a bellcrank lever for rotating the support rods simultaneously with the lifting or lowering of the door relative to the support rods, whereby the hinges can be moved from a recessed position inside the door structure when the door is closed into an extended position outside the door structure for opening the door.
