Abstract: A full size building having three walls, an open side and a roof but no floor can be moved along parallel rails from an open free standing position to a closed position where the building abuts another structure to completely enclose an outdoor area. The building is of conventional construction but is erected over a rigid framework of iron beams. A series of roller assemblies containing rotatable axles is attached to the underside of rigid framework. The axles rest directly on the rails and rotate smoothly by means of bearings as the building moves along the rails. Stabilizers prevent wobble and keep the building on the rails when it is being moved. Locks prevent any movement when the building is in either the open or closed position. Additional locking means prevent lateral movement when the building is locked in the open position. The building can be moved using a winch and cable system or using a unique suspended sprocket wheel and track system. Concrete footings form the base for the rails.

Abstract: A slide-out or retractable room for a mobile living quarters, such as a recreational vehicle, is provided with actuating assemblies mounted on opposite side walls of the slide-out room and the adjacent wall of the main living area. The actuating assemblies include a pair of parallel gear racks mounted on the side wall, which are engaged by pinions rotated by torque shafts mounted on the main living quarters. Each torque shaft is rotated by a separate motor. A roller engages a bearing surface on the lower portion of the gear racks. Accordingly, the slide-out room is extended and retracted by rotating the torque shafts to cause the gear racks and the attached slide-out room to extend and retract. The weight of the slide-out room is supported by the rollers, thereby supporting the slide-out room off of the floor of the main living quarters as it extends and retracts. A synchronizing control operates the motors.

In this respect, the movement of the top of the slide-out room is synchronized to the bottom, providing synchronized extension or retraction at equal or varying speeds.

Abstract: A compound motion travel lock secures a slide-out section of a vehicle in a retracted position. A lock arm moves in a compound pivoting and translating movement as a manual or power driven actuator provides a linear input to a cam pin and slot arrangement. The rotational input is converted to a linear force acting on the lock arm, which pivots out from a collapsed position by engagement of the cam pins in the cam slots. The pivoted out lock arm is then translated to an engaged position in which the lock arm clamps against an interior surface of the vehicle to retain the slide-out section retracted within the vehicle. When the lock arm is collapsed the slide-out section can be moved freely between retracted and extended positions.
