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.

An aircraft door bolt actuating mechanism, comprising: a bolt actuating crank having positions of rotation corresponding respectively to the bolted and unbolted positions of the door bolt; inside and outside door handles connected for unitary rotation and for rotating said crank; means for moving said outside handle between a generally flush retracted inactivated position and an extended activated position for manually operating said crank including: an actuating member operatively connected with said outside handle, said member being supported for unitary rotation with said handles and for reciprocable movement in one direction, to retract the outside handle and in a reverse direction to extend said outside handle; spring means for urging said member in said one direction; and means responsive to the rotation of said member for moving said member in said reverse direction. An aircraft door bolt actuating mechanism, comprising: a frame structure adapted for mounting on said door; a bolt actuating crank rotatably supported on said frame structure for movement to bolted and unbolted positions; inside and outside door handles carried by said frame structure connected for unitary rotation and for rotating said crank; and said outside handle having a T-shaped configuration and comprising a pair of oppositely extending hand-grip portions having their adjacent ends pivoted on a common pivot and connected by by interconnecting means for unitary swinging movements between a retracted axially aligned position and an extended position with the hand-grip portions in angular outwardly diverging relation. An aircraft door bolt actuating mechanism, comprising: a bolt actuating crank having positions of rotation corresponding respectively to the bolted and unbolted positions of the door bolt: inside and outside door handles connected for unitary rotation and for rotating said crank, said outside door handle being pivoted at one end for swinging movements between a generally flush retracted inactivated position and an extended activated position for manually operating said crank; means for moving said outside handle, including: an actuating member operatively connected with the pivoted end of said outside handle, said member being supported for unitary rotation with said handles and for reciprocable movement in one direction to retract the outside handle, and in a reverse direction to extend said outside handle; spring means for urging said member in said one direction; and means responsive to the rotation of said member for moving said member in said reverse direction.
