Synchronization device for a slide out room

摘要

A synchronization device for use on recreational vehicles having slide out rooms that keeps the slide out room properly aligned with the frame of the recreational vehicle in order to ensure smooth operation. The device of the present invention includes a pair of elongated extensible members that connect the moveable frame to the fixed frame. Each of the members includes an inner end pivotally mounted to the fixed frame and an outer end pivotally mounted to the moveable frame, with the extensible members being shiftable between a folded, shortened position and an unfolded, extended position as the slide out room is extended. Each extensible member includes a hollow outer leg an extensible inner leg that is telescopically disposed within the outer leg. A pinion interconnects the extensible members and synchronizes the extension and retraction of the inner legs relative to the outer legs, and also synchronizes the folding or unfolding of the extensible members. Thus, the moveable frame remains parallel to and aligned with the fixed frame at all times.
