Device for limiting the deflection on a door arranged in a fuselage cell of an aircraft

摘要

The invention relates to a device for limiting the deflection of a door (1), particularly a hatch or a freight door, arranged in a fuselage cell (3) of an aircraft, having at least one holding element (5) arranged preferably in the region of a door jamb (4) or in the region of a door leaf edge (7).;In order to ensure deflection limitation for doors, hatches and freight doors in aircraft which can be triggered manually independently of an actuation of the normal locking system, it is proposed according to the invention that the at least one holding element (5) can, if there is a sufficient pressure difference Δp between the internal pressure pi prevailing in the fuselage cell (3) and the outside air pressure pa prevailing outside of the fuselage cell (3), be brought into engagement with at least one abutment (6) arranged in the region of the door leaf edge (7) or the door jamb (4).;In addition it is proposed that if there is a sufficiently large pressure difference Δp the at least one holding element (30, 55) is automatically pivoted or can be manually pivoted and can hereby be brought into engagement with the at least one abutment (31, 52).

主权项

1. A device for limiting deflection of a door having a pivoting door leaf edge and the door being arranged in a fuselage cell of an aircraft, the device comprising:
at least one abutment; and at least one holding element; wherein the at least one holding element is pivotable automatically in case of a sufficiently large pressure difference between internal pressure in the fuselage cell and outside air pressure, whereby the at least one holding element is brought into engagement with the at least one abutment while the door is in a closed position; and wherein the at least one holding element comprises a lever coupled to an elastic membrane which has a hook and the at least one abutment comprises a barbed hook, and wherein the elastic membrane is subjected to a pressure difference between the internal pressure and the outside air pressure such that if there is the sufficiently large pressure difference the hook is brought into engagement with the barbed hook.
