An elevator system for use in a wide-body commercial aircraft having multiple levels within the aircraft provides an elevator shaft that extends through at least two of the levels of the aircraft. The elevator shaft communicates with an opening in the hull of the aircraft. An elevator car is mounted within the shaft and controls and a drive unit are associated with the car to move it within the shaft and also out through the opening in the hull to provide access to and from the aircraft. At least a portion of the car remains in the shaft at all times to provide some lateral stability to the car.

Personnel elevator for commercial aircraft

This invention relates to removable systems for supporting interior passenger elements within an aircraft fuselage (1). The invention is directed toward increasing the efficiency of load transfer, providing quick conversion, and maximizing cargo space. A plurality of longitudinal sections (2, 2') are arranged end-to-end along an axis and connected together by extension/retraction joints (14, 28, 28'). A first end of a diagonal strut (8, 50, 50') is nontranslatably connected to a section (2, 2') just forward of each joint (14, 28, 28'). The other end of strut (8, 50, 50') is nontranslatably connected to the fuselage (1) aft of joint (14, 28, 28'). Axial loads on sections (2, 2') cause sections (2, 2') to slip axially relative to each other, and such loads are transferred from sections (2, 2') to struts (8, 50, 50') and are reacted through fuselage (1). Vertical and side loads are reacted by transverse members (4, 4') that are slip-connected to fuselage ( 1) and by vertical trusses (6, 40).
