ABSTRACT:
The present application relates to a specially designed hinge mechanism (4) which makes it possible to construct an aircraft door (2) that can be fitted in a fuselage (3) so as to be displaceable and swivellable on the fuselage (3). Furthermore, the invention relates to an aircraft door (2) comprising at least one such hinge mechanism (4) designed in this way, to a fuselage (3) with at least one aircraft door (2) that is linked to at least one hinge mechanism (4), designed in this way, on the fuselage (3), as well as to the use of at least one hinge mechanism (4) for installation of an aircraft door (2) on a fuselage (3). The hinge mechanism (4) essentially comprises a displacement mechanism (5, 6) as well as a telescopic scissor-type mechanism (7-12). The displacement mechanism (5, 6) can be linked to an aircraft door (2) and is kinematically designed such that as a result of its activation the aircraft door (2) can be displaced from its home position in the direction of the fuselage (3). The scissor-type mechanism (7-12) can be linked to a fuselage (3) and is kinematically designed such that as a result of its activation the aircraft door (2) is displaceable from the fuselage (3) to a final position, on a polar axis that is aligned perpendicularly in the direction of displacement.
