  • Hydraulic slide out assembly and method of operation
    Patent number: 6655723
    Abstract: A vehicle including a stationary floor and an upwardly extending exterior wall fixed relative to the stationary floor. An opening formed in the exterior wall receives a slide-out section disposed therein, The slide-out section is movable relative to the stationary floor between an extended position and a retracted position. An actuating mechanism controls the movement of the slide-out section. The actuating mechanism includes at least one hydraulic actuator having an extendible ram extendible from a cylinder. The extendible ram is fixed to at least one of the stationary floor and the slide-out section, and the cylinder is fixed to the other of the stationary floor and the slide-out section. Retraction of the extendible ram slidably moves the slide-out section to the extended position.
