摘要： A cableless extendable and retractable support system for raising and lower a structure that includes a base, a structure to be raised and lowered relative to the base, a plurality of telescopic assemblies coupled between the base and structure to be raised and lowered, a plurality of spring elements having ends that are coupled between the plurality of telescopic assemblies and a lift tube assembly, the lift tube assembly including a mechanism which, when activated, selectively extends or retracts each of the plurality of spring elements therefrom and a housing which encloses the entire mechanism that extends and retracts the plurality of spring elements. According to one embodiment, the mechanism that extends and retracts the plurality of spring elements includes a drive screw and a driven screw and a pair of opposed push blocks which are mounded on the drive and driven screws, the first ends of each of the plurality of spring elements being coupled to the pair of push blocks. According to another embodiment of the invention, the mechanism that extends and retracts the plurality of spring elements includes a drum assembly upon which pairs of the spring elements are wound in opposite direction and a drive assembly to rotate the drum assembly.

摘要： A full body slide out room assembly is comprised of a vehicle with stationary end modules, a stationary roof and a plurality of moveable room assemblies that consist of a telescoping roof, floor, anterior walls, and end walls. The sliding movement of each room is controlled by one or more linear drive mechanisms that are pneumatic, hydraulic, mechanical, electro-mechanical, or combination of two or more of these methods. Each moveable room is supported by a center or offset longitudinal truss or trusses below the floor level, and a plurality of guide rails and support rails located between the vehicle chassis and the moveable room. Polymer plates are installed between the support and guide rails.
