ABSTRACT:
A space-saving, single-cylinder, room extender, this invention consists of a hydraulic cylinder, electrically powered screw auger or other electrically powered means is nested within an inner structural member that is, in turn, telescopically nested within an central beam. Further, the nested structural members form an integral part of the structure of the expandable room being embedded within the floor of the room, or being embedded within the structural frame of an accessory within the room. Low friction shims hold the inner structural member within the central beam such that lateral motion is minimized while the telescopic motion of central beam relative to the inner structural member is smooth.
