Abstract
An airplane door is swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of a fuselage, and including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm. During the movement of the lifting or lowering of the door, the transmission line of the driving device for the swivelling is uncoupled so that it is not unnecessarily mechanically stressed and a jamming of the transmission line therefore basically does not occur.

Arrangement for moving an airplane door swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of the fuselage, and including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm,
- wherein the driving device for the swivelling has a drivable engaging element arranged on its output which, when the door is lifted, engages with a receiving element which is arranged on the supporting arm, and the drivable engaging element and the receiving element form a coupling device for transmitting the swivelling force.
Arrangement for moving an airplane door swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of the fuselage, and including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm,
- wherein the driving device for the swivelling is arranged on the supporting arm and a drivable engaging element is arranged at the output of the driving device, which engaging element, during the lifting of the door, engages with a receiving element arranged at the door, and the drivable engaging element and the receiving element form a coupling device for transmitting the swivelling force.
Arrangement for moving an airplane door swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of the fuselage, including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm,
- wherein the driving device for the swivelling is arranged on the frame of the fuselage and a drivable engaging element is arranged at the output of the driving device, which engaging element, during the lifting of the door and the supporting arm, engages with a receiving element arranged on the supporting arm, and the drivable engaging element and the receiving element form a coupling device for transmitting the swivelling force.
Arrangement for moving an airplane door swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of the fuselage, including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm,
- wherein the driving device for the swivelling is arranged on the supporting arm and a drivable engaging element is arranged at the output of the driving device, which engaging element, during the lifting of the door and of the supporting arm, engages with a receiving element arranged on the door frame of the fuselage, and the drivable engaging element and the receiving element form a coupling device for transmitting the swivelling force.
An airplane assembly comprising:
- a fuselage part with a passenger door opening,
- a door, and
- a door support assembly operable to move the door between a door opening closing position and an open position,
- wherein the door support assembly includes:
- a supporting arm pivotal about a supporting arm pivot axis disposed on the fuselage part,
- a door lifting device operable to lift and lower the door,
- a door swivelling device for accommodating swivelling of the door with respect to the supporting arm about a door swivel axis disposed on the supporting arm, and
- a detachable coupling between the door swivelling arm and the door swivelling device,
- wherein said detachable coupling is configured to separate the door swivelling arm and the door swivelling device from one another when said door is in a lower closed position and to connect the door swivelling arm and the door swivelling device when said door is in a raised position during opening of said door.
