  • Manual override for slide-out room system having wall-mounted drive mechanism
    Patent number: 9545870
    Abstract: An apparatus for moving a slide-out room disposed in an aperture of a side wall of a vehicle from a retracted position to an extended position in a drive direction. The apparatus includes a drive assembly supported by the side wall of the vehicle and a driven assembly driven by the drive assembly. The driven assembly is connected to a wall of the slide-out room such that the slide-out room moves with the driven assembly from the retracted position to the extended position in the drive direction and the driven assembly is movable in a transverse direction generally perpendicular to the drive direction relative to the wall of the slide-out room.
