ABSTRACT:
A handle assembly used for actuating the latch mechanism of an aircraft door to control the opening and the closing of the aircraft door. The handle assembly includes an interior handle, an exterior handle, an actuator, and an exterior housing having a recess. The interior handle and the exterior handle each have an open and a closed position, respectively, and are connected to the actuator. The actuator is rotatably mounted within the exterior housing and the exterior housing is mountable within the aircraft door. The actuator may be secured to the latch mechanism of the aircraft door and the latch mechanism may be operated by the actuator. The rotation of the interior handle to the open position moves the actuator such that the latch mechanism is actuated to the open position allowing the aircraft door to be opened. A cam is connected to the interior handle and is rotatably mounted relative to the exterior handle. During the initial rotation of the interior handle towards the open position, the cam is rotated such that the exterior handle is pushed outwards from the recess of the exterior housing. During the further rotation of the interior handle, the exterior handle rotates in unison with the interior handle towards the open position. The handle assembly also includes a biasing element, such as a spring. When the interior handle is rotated to the closed position, the biasing element automatically pulls the exterior handle back into the recess of the exterior housing.
