ABSTRACT:
A portable display assembly for use in displaying a variety of articles on a wall structure thereof, being structured for easy assembly and disassembly to facilitate transport between different use locations. The display assembly includes a plurality of vertical frame units which are adapted to be interconnected at spaced intervals by scissor connectors. The scissor connectors each include a pair of elongate, rigid elements pivotally attached at mid-portions thereof forming oppositely disposed scissor arms, wherein each pair of scissor arms is structured for attachment to a respective one of adjacently positioned vertical frame units in such a manner so as to position the adjacent frame units in either a parallel orientation or one of a plurality of angled orientations relative to one another. In this manner, a wall frame structure of virtually any desired size, shape and configuration can be assembled, to which may be attached decorative background panels, shelves, and other display material.
