ABSTRACT:
A portable display apparatus is herein disclosed. The portable display apparatus is composed of a plurality of rectangular skeletal frames. Each rectangular skeletal frame of said plurality includes a horizontal hinge, adapted to enable said frame to fold vertically. Each rectangular skeletal frame of said plurality is identical to all other rectangular skeletal frames of said plurality. Each of said frames includes a plurality of opposite vertical members. Each of said vertical members is identical to all other vertical members. Each of said vertical members has a connector portion, and a track portion. Each of said rectangular skeletal frames is adapted to be bolted to other rectangular skeletal frames in either a fixed or pivotal relationship at the connector portions of the vertical members. Each of the rectangular skeletal frames is also adapted to be hingedly connected to the other rectangular skeletal frames. The track portions are adapted to receive a display panel within track portions. The track portions are positioned so that the connector portions do not interfere with the track portions or display panels.
