Abstract

Abstract A plurality of generally rectangular frames (21) releasably hinged together and having display panels (36) mounted in display areas defined by the frames. Each frame is of tubular metal of rectangular cross section and includes a horizontal top frame member (19), having downturned end portions, and a U-shaped bottom frame member (21), having laterally spaced vertical tubular side frame portions with longitudinal slots. Connector pins (26) make sliding connection between the top frame member and the bottom frame member. Display panels in the display areas are formed with laterally projecting mounting tabs (37) that are received in the slots of the side frame members, and of the connection pins if necessary, to hold the panels in place. Supporting legs (15), which may also be of tubular material, have pivoting yokes (32) at their upper ends that slidingly engage the bottom frame portions of the frames, and clamping elements (39) releasably lock the bottom frame portions against sliding movements in the yokes: for table mounting, simple nonpivoting supports (142) are provided. Lighting fixtures (121) are slidably secured to the tops of the frames.
