ABSTRACT:
The disclosure teaches an improvement to a type of novel modular display panel which in the prior art required removal of the frames in rearranging. The improved system can be quickly assembled, disassembled, rearranged and newly assembled in different panel order without the necessity of taking the panels out of their frames. Multiple panels are joined together by means of elongate vertical frames and center posts having reciprocally mating splines and keyways which freely move longitudinally such that the center post can be slipped out, the panels rearranged and the center post put back in to position. The stability of the system is secured by providing a temporary removable insert in the keyways carrying an elastomeric material which is expanded to frictionally engage the side walls of the keyways. The elastomeric material can be reversably contracted to release the sidewalls.
