ABSTRACT:
An elevationally adjustable mobile folding stage includes two independent stage members pivotally connected for movement between an operational position and a folded storage position. Support legs are pivotally mounted to the two stage members and are pivotally connected to cross brace linkage means which interconnect the support legs and the stage members for automatically folding the legs when the stage members are pivoted to their folded position. The legs of the stage are elevationally adjustable and include roller wheels for mobility of the stage when in its folded position. A counter balance spring system is provided to assist in folding the stage.
