  • Patent number: 5078442
    Abstract: A portable performance platform for the performing arts is disclosed that, in the stowed configuration, can be transported along roads and highways, and, in its unfolded configuration, presents an extended performing area having an overhead canopy. The platform includes a chassis mounted on ground engaging wheels. A pair of spaced apart, upright standards are positioned along one side margin of the chassis. Each standard includes an articulated arm that can be shifted between a stowed position (for transport of the platform) and an extended position (when the platform is set up for a performance). The articulated arm includes two arm members, and panels are fixedly carried by each of the arm members. In the stowed position, the panels make up a top wall and a sidewall of a staging compartment, and, when the arms are in the extended position, the panels provide a canopy over the performing area.
