Abstract

A locking system for an aircraft door having a door handle housing to mount to the aircraft door; a locking mechanism supported by the door handle housing; an exterior handle and an interior handle each to manipulate the locking mechanism. The locking mechanism having a door gear axis to rotate via operation of the interior handle and the exterior handle to lock and unlock the locking mechanism; and a locking pin extending from the door gear axis and into a chamber of the door handle housing, the locking pin having a first position and a second position, the first position of the locking pin blocks rotation of the door gear axis and the second position of the locking pin allows rotation of the door gear axis. The locking pin is moveable from the first position to the second position via operation of the interior handle and the exterior handle.

Dependent claims

A locking system for an aircraft door as part of an aircraft, the locking system comprising:

a door handle housing configured to mount to the aircraft door;
a locking mechanism supported by the door handle housing;
an exterior handle configured to open the aircraft door by manipulating the locking mechanism from an exterior of the aircraft;
and
an interior handle configured to open the aircraft door by manipulating the locking mechanism from an interior of the aircraft;
the locking mechanism having:
a door gear axis configured to rotate via operation of the interior handle and the exterior handle to lock and unlock the locking mechanism;
a locking pin extending from the door gear axis and into a chamber as part of the door handle housing, the locking pin having a first position and a second position;
and
a handle lock button positioned within the chamber created by the door handle housing, the handle lock button configured to pivot about a pivot point such that the handle lock button engages with the locking pin to depress the locking pin to the second position;
wherein in the first position the locking pin blocks rotation of the door gear axis;
and
wherein in the second position the locking pin allows rotation of the door gear axis;
wherein the locking pin is moveable from the first position to the second position via operation of the interior handle and the exterior handle such that the interior handle and the exterior handle can independently move the locking pin into the second position to operate rotation of the door gear axis.
