Abstract
The present invention provides an aircraft landing bay door mechanism that includes the use of a roller slot mechanism for opening and closing the landing bay door.
Claims18
An aircraft landing gear roller slot mechanism for opening and closing a landing gear bay door comprising:
- a drive rod pivotably coupled at one end to the aircraft landing gear;
- an input crank pivotably coupled at a first end to the drive rod, at the opposite end of the drive rod from the landing gear, the input crank including a connecting means located at a second end;
- an output crank comprising a slot defined at one end thereof, the slot being configured to receive the connecting means therein;
- and
- a door rod pivotably coupled to the output crank at the opposite end of the output crank to the slot, the door rod further coupled to the landing gear bay door.

An apparatus for opening and closing a door of a landing gear bay in an aircraft comprising:
- mechanical coupling means coupling the landing gear and the door, the coupling means comprising:
- a drive rod coupled to the landing gear and a door rod coupled to the landing gear bay door;
- an input crank coupled at a first end to the drive rod, opposite the end of the drive rod that is coupled to the landing gear;
- and
- an output crank, coupled at a first end to the door rod;
- the input crank and the output crank independently pivotably coupled to the landing gear bay and further coupled to each other and configured so that pivotal movement of the input crank results in pivotal movement of the output crank thereby providing for the opening and closing of the bay door.
3 more elements
An aircraft landing gear bay door opening and closing apparatus comprising:
- a drive rod pivotably connected to the landing gear;
- a door rod coupled to the landing gear bay door;
- an input crank pivotably connected, at a first end, to the drive rod and coupled to the landing bay about an input crank pivot point;
- an output crank pivotably connected to the door rod and coupled to the landing bay about an output crank pivot point;
- at least one of the input and the output crank having connecting means located thereon, configured to connect the input and output cranks so that movement of the input crank translates to movement of the output crank and opening or closing of the landing gear bay door.
