Abstract
A door assembly, particularly for doors of passenger aircraft, includes a door frame, a door having a door body hingedly installed in the door frame, at least one hooking pintle attached to the door frame or an edge of the door body extending along a pintle axis, and at least one door latch connected to an edge of the door body or the door frame, respectively, the door latch having a substantially C-shaped latch body configured to rotate around an axis parallel to the pintle axis of the hooking pintle. The door assembly further includes a bistable latch and hook mechanism configured to catch the door latch in hooking engagement with the hooking pintle and to retain the door latch in a direction perpendicular to the door body in an overcenter position.
Claims14
A door assembly, comprising:
- a door frame;
- a door having a door body hingedly installed in the door frame;
- at least one hooking pintle attached to the door frame or an edge of the door body extending along a pintle axis;
- at least one door latch connected to the edge of the door body or the door frame, respectively, the at least one door latch having a substantially C-shaped latch body configured to rotate around an axis parallel to the pintle axis of the at least one hooking pintle;
- and
- a bistable latch and hook mechanism configured to catch the at least one door latch in hooking engagement with the at least one hooking pintle,
- wherein the at least one door latch further comprises an arresting notch formed off-center to the C-shaped latch body.
An aircraft, comprising an aircraft door with a door assembly, the door assembly comprising:
- a door frame;
- a door having a door body hingedly installed in the door frame;
- at least one hooking pintle attached to the door frame or an edge of the door body extending along a pintle axis;
- at least one door latch connected to the edge of the door body or the door frame, respectively, the at least one door latch having a substantially C-shaped latch body configured to rotate around an axis parallel to the pintle axis of the at least one hooking pintle;
- and
- a bistable latch and hook mechanism configured to catch the at least one door latch in hooking engagement with the at least one hooking pintle;
- and
- a monitoring system connected to the door assembly and configured to prevent ventilation of pressurization of the aircraft depending on the operational state of the door assembly.
A method for operating a door assembly, the door assembly comprising:
- a door frame;
- a door having a door body hingedly installed in the door frame;
- at least one hooking pintle attached to the door frame or an edge of the door body extending along a pintle axis;
- at least one door latch connected to the edge of the door body or the door frame, respectively, the at least one door latch having a substantially C-shaped latch body configured to rotate around an axis parallel to the pintle axis of the at least one hooking pintle;
- and
- a bistable latch and hook mechanism configured to catch the at least one door latch in hooking engagement with the at least one hooking pintle,
- wherein the at least one door latch further comprises an arresting notch formed off-center to the C-shaped latch body,
- the method comprising:
- rotating the C-shaped latch body from an overcenter position of the bistable latch and hook mechanism to a deadcenter position of the bistable latch and hook mechanism around the at least one hooking pintle in at least partially deeper hooking engagement with the at least one hooking pintle;
- and rotating the C-shaped latch body over the deadcenter position in the opposite direction around the at least one hooking pintle out of the hooking engagement with the at least one hooking pintle.
