A retractable room for mobile living quarters includes a floor which slides along the floor of the main living quarter when the retractable room is retracted therein, but drops into a position flush with the main floor when the retractable room is extended into its extended position. A linkage operates a riser mechanism to raise and lower the floors as the room is extended and retracted. The riser mechanism is operated by a lever which pivots in response to movement of the floor to a predetermined position relative to the main living quarters.

[ What is claimed is:] [17.] Mobile living quarters comprising a frame, a main floor supported by said frame, means extending from said main floor to define with said main floor a main living area, a retractable room mounted for movement from a retracted position within the main living area to an extended position extended from said main living area to provide an auxiliary living area, said retractable room having walls and a movable floor movable along said main floor with the walls, from a sliding position sliding upon said main floor to a flush position substantially flush with said main floor when the retractable room is in the extended position, retractable room support means mounted on said frame and engaging said retractable room to guide the latter for movement relative to said frame, said retractable room support means includes a pair of coaxial, relatively movable tubular members, linkage means operated by said retractable room support means and a riser mechanism mounted for movement with the retractable room for controlling movement of said movable floor relative to said main floor, said linkage means including an elongated member having one end engaging said riser mechanism and an opposite end having a lever actuator for moving said elongated member relative to said riser mechanism, said linkage means further including a camming surface mounted on said retractable room support means and a cam follower engaging said camming surface as the floor is lowered into said flush position, said linkage means engaging said riser mechanism through a sliding connection to move said movable floor into said flush position as said retractable room is moved into said extended position, said lever actuator being mounted for sliding and pivotal movement relative to said tubular members, said tubular members including an axial extending slot and a track extending parallel to said slot, said linkage means including an elongated member pivotally connected to said lever actuator and including a portion extending through said slot, said follower being mounted on said portion, and a roller mounted on said portion and rolling along said track as the movable floor moves along said main floor.
