Abstract

An aircraft door latching bolt actuating mechanism in which inside and outside handles are provided to actuate a crank having connections with one or more door latching bolts. The outside handle comprises a T-shaped handle with oppositely extending hand-grip portions for two hand actuation, and which are pivoted for swinging movement between a generally flush retracted position in which the hand-grip portions serve to releasably latch the crank against movement to a bolt releasing position, and an extended non-latching position permitting movement of the crank to the bolt releasing position. The hand-grip portions are interconnected with a common actuating and equalizing member that is supported for rotation with the inside and outside handles, and also for independent reciprocal movements in opposite directions. A spring normally urges the actuating member in a direction to move the hand-grip portions into their retracted positions, and a cam is arranged to move the actuating member in the opposite direction and extend the hand-grip portions of the outside handle, when rotated by the inside handle. A finger receiving opening in one of the end grip portions of the outside handle enables movement of the hand-grip portions to their extended released positions and thus permits actuation of the crank to bolt releasing positions by means of the outside handle.
