ABSTRACT:
A locking system is disclosed for rigidly joining together in various configurations display panels having at least one straight edge having an elongated longitudinal undercut retainer channel along that edge. The system comprises a pair of telescoped inner and outer tubular members carrying a plurality of longitudinally spaced and aligned locking members adapted to engage the retainer channels of the panels to be joined. The locking members are retracted for assembly of adjacent display panels, or extended for disassembly, upon relative reciprocal movement of the tubular members. The mechanism for accomplishing reciprocation is described. Locking systems for assembly of display units of various configurations are described.
