发明名称 Portable stage apparatus
摘要 A portable stage apparatus which utilizes a plurality of open frame assemblies, each of which is constructed of a plurality of pivotally interconnected side panels. Each open frame assembly is mounted on wheels to facilitate movement from a collapsed position to an extended position. When in the extended position, a plurality of floor panels are to be mounted on the open frame assemblies with the floor panels being contiguous and the upper surface of the floor panels being in alignment. Adjoining floor panels are interlocked together with these floor panels also being locked to the open frame assemblies. For purposes of stowage and transportability, the open frame assemblies are connectable together in the collapsed position and readily movable onto a transporting vehicle. Also, a group of the floor panels are capable of being stowed together into a small space and mounted onto a storage dolly which is readily movable onto and off of a transporting vehicle.
