ABSTRACT:
A display system includes a collapsible, rectangular frame having a plurality of rectangular box units. Each box unit includes rectangularly arranged sides which are defined by a pair of arms, joined to one another by a scissor connection. The top and bottom side arms include at least one telescoping member therein. Connector-block nodes are located at each corner of the box units and include pivot means for securing the arms thereto for permitting the frame to be collapsed to a compact form. Plural display supports extend along files of connected block nodes on the front face of the frame, each support extending between adjacent connector block nodes and including a pair of display-support runners. The display-support runners are joined to one another at one, central end thereof by a central hinge and joined to a connector block node at the other end thereof by an end hinge.
