Abstract
The invention relates to a stop armature of an armature system of an aircraft door with a fuselage stop armature (10) and a door stop armature (12, 79), with a stop screw (30; 40; 60) in one of the two stop armatures (10, 12 or 79), which can be pressurized by the other stop armature (10) in the longitudinal direction of the screw (30; 40; 60; 80) on a locating face (34; 52; 70; 88). It is further developed by virtue of the fact that the screw (30; 40; 60; 80) encompasses a screw head (32; 42; 69) with a ball (36; 50; 68; 85) held therein that can rotate around its midpoint (M) as the fulcrum. The invention also relates to a stop screw for a stop armature and the use of a ball thrust screw as the stop screw.
Claims13
A door stop system for an aircraft, said aircraft having a fuselage and a door mounted on the fuselage, the door stop system being provided with:
- a fuselage stop armature having securing means for said fuselage stop armature to be bonded on said fuselage of the aircraft
- a door stop armature having securing means for said door stop armature to be bonded on said door of the aircraft,
- a stop screw holder being held on one of the fuselage stop armature or door stop armature,
- a stop screw screwed in said stop screw holder extending in a longitudinal direction, said stop screw having a locating face for contact with the fuselage stop armature or the door stop armature other than the door stop armature or the fuselage stop armature that holds the screw wherein
- the stop screw includes a screw head having an inner cylindrical lateral wall forming a concave pan;
- said door stop system further including a ball defining a midpoint (M) as a fulcrum;
- said ball having a smaller rounding off radius relative to the cylindrical lateral wall of the screw head;
- said ball being rotatably-mounted in the concave pan of the stop screw, so as to rotate around said midpoint (M), said midpoint (M) being encompassed by said cylindrical lateral wall of the concave pan;
- said ball including a projecting portion that partly projects in the longitudinal direction out of the cylindrical lateral wall;
- the locating portion being fixed to the projecting portion of the ball, so that the locating face can be tilted by a swiveling angle (α) together with the ball;
- and
- the door stop system further including abutment means so that the swiveling angle (α) is up to 9 degrees.
