Patent ID: 7883058

Claim:
A hinge mechanism for the displaceable and swivellable installation of an aircraft door, which can be fitted to a fuselage, in said fuselage, comprising: a first rocker arrangement comprising a first displacement link and a second displacement link, the first rocker arrangement being linkable to the aircraft door and being kinematically designed such that as a result of its activation the aircraft door is displaced circumferentially from its locked position in a direction almost tangential to a circumferential direction of the fuselage, defined by the outer surface of the fuselage, so that the door is unlocked; and a second rocker arrangement comprising a first swivel link and a second swivel link, the second rocker arrangement being linkable to the fuselage and being kinematically designed such that as a result of its activation the aircraft door can be swivelled from the unlocked position to a final position, around a polar axis that is aligned perpendicular to the direction of displacement; wherein the first rocker arrangement kinematically interacts with the second rocker arrangement in such a way that as a result of continuous force impingement on one of the two rocker arrangements, the first rocker arrangement moves through its complete range of motion relative to the aircraft door and afterwards the second rocker arrangement moves through its complete range of motion relative to the aircraft door such that the first rocker arrangement stops moving relative to the aircraft door before the second rocker arrangement starts moving relative to the aircraft door.
