Aircraft elevator system and method

摘要

An aircraft elevator system includes a fixed frame, a floating frame coupled to the fixed frame, and a cabin coupled to the floating frame. The floating frame can move with respect to the fixed frame and the cabin can move with respect to the floating frame. The system can include an actuating system operating at least one pulley system to move the cabin between upper and lower positions, which respectively can be inside and outside the aircraft. In some embodiments, the system includes a support assembly that moderates or eliminates load transfer between the system and an aircraft upper deck floor structure. In some embodiments, the cabin includes a ramp configured to deploy when approaching the lower position and to retract to a stowed position when the cabin moves from the lower position toward the upper position. The ramp can include a sensor to control cabin movement.

1. An aircraft elevator system comprising:
a cabin; a primary frame; a secondary frame having upper and lower ends; a first coupling system arranged to moveably couple the primary frame to the secondary frame, the first coupling system configured to move the secondary frame relative to the primary frame; and a second coupling system arranged to moveably couple the cabin to the secondary frame, the second coupling system configured to move the cabin relative to the secondary frame between upper and lower positions and operable simultaneously with the first coupling system such that in the upper position the cabin is situated toward the upper end of the secondary frame and in the lower position the cabin is situated toward or below the lower end of the secondary frame.
