Abstract
The present invention provides a double hook door mechanism for use in opening and closing aircraft landing gear bay doors.
Claims19
An apparatus for opening and closing a door of a landing gear bay in an aircraft comprising:
- a first hook mechanism pivotably coupled to the landing gear bay;
- a second hook mechanism pivotably coupled to the landing gear bay and further coupled to the landing bay door:
- the first and second hook mechanism coupled to each other and configured to simultaneously rotate in opposing directions, rotation of the first and second hook mechanisms resulting in opening or closing of the bay door.
A landing gear door mechanism for use with an aircraft landing gear, the landing gear including a projection thereon, the door mechanism comprising:
- a first connector connected to the aircraft airframe at a first connection point and configured to rotate about the first connection point;
- a second connector, connected to the first connector and to the landing gear door and further connected to the aircraft airframe at a second connection point, the second connector configured to rotate about the second connection point;
- each of the first and second connectors being configured to independently rotate about their relative connection points in opposing directions relative to each other and configured to independently releasably connect with the landing gear, the rotation of the first and second connectors and the releasable connection of each connector to the landing gear providing for the opening and closing of the landing gear door
A device for opening and closing an aircraft landing gear bay door, comprising:
- a door rod coupled to the landing gear bay door;
- a first connection means, pivotably coupled to the door rod at a first end and pivotably coupled to the landing gear bay at a first connection point;
- a second connection means, coupled to the first connection means, and pivotably coupled to the landing gear bay at a second connection point;
- the first and second connection means configured to independently releasably connect with a pivot point located on the landing gear.

A device for opening and closing a landing gear bay door comprising:
- a door rod coupled to the landing gear bay door at a first end;
- a first connector, pivotably coupled to the landing bay at a first connection point;
- a second connector, pivotably coupled to the landing bay at a second connection point and coupled to the door rod at its second end;
- the first and second connectors coupled to each other and configured to simultaneously rotate in opposing directions, the first and second connectors configured to independently engage with a projection located on the landing gear, engagement of one of the first and second connectors with the projection causing rotation of the connectors which translates to movement of the door rod to open or close the bay door.
