Abstract
A collapsible modular display tower assembly has a three-dimensional, collapsible display panel structure having two opposing pairs of pivotally-connective links with upper and lower ends arranged to form four side faces when erect. A plurality of upper and lower hub assemblies are pivotally connecting the adjacent ends of the links of adjacent side faces. Four vertically-oriented expansible support and attachment braces are provided with each brace being connected to one pair of the vertically-aligned upper and lower hub assemblies. The braces permit the attachment of graphic representations and display accessories to the tower assembly. Releasable hub-connecting means in the form of male and female connectors are provided on the upper and lower hub assemblies for releasably interlocking a multiplicity of display panel structures into a vertical display tower.
