Linkage for guiding a retractable room

摘要

A mobile living quarters includes a retractable or slide out room mounted for movement from a retracted position retracted within the main living area to an extending position providing auxiliary living area connected to the main living area. A scissors linkage is connected between the main frame and the retractable room for guiding the retractable room during extension and retraction and also equalizing forces on opposite sides of the retractable room to prevent binding. The scissors linkage includes a pair of arms which are pivotally connected to the frame of the mobile living quarters and to the retractable room. The pivots include a sliding pivot to accommodate sliding of the scissors arms as extension and retraction of the retractable or slide room occurs. A hydraulic actuator effects extension and retraction of the slide out room. The scissors linkage is mounted between the outer edge of one of the main frame member and the retractable room, thereby avoiding interference from other underbody components mounted on the frame members.
