PCT No. PCT/SE87/00178 Sec. 371 Date Oct. 21, 1988 Sec. 102(e) Date Oct. 21, 1988 PCT Filed Apr. 8, 1987 PCT Pub. No. WO87/06754 PCT Pub. Date Nov. 5, 1987.A display rack consists of flat pane display frames to be interconnected by coupling members. The frames comprise corner pieces and side frame members of extruded profiled tubes with two parallel tube portions and two longitudinal grooves in the plane of the display frame. The corner pieces have at least two pairs of parallel legs to be inserted and adopted by the tube portions. Of the longitudinal grooves at least one externally located groove of each display frame has an external opening narrower than the rest of the groove to prevent a dowel member introduced into the groove from passing out transversely. The corner pieces have cavities in the extension of the recessed grooves to permit the dowel members to be passed through the corner piece and into said recessed groove. Each coupling member has at least two dowels each of which is adapted for introduction through one of the cavities of a corner piece and further into the corresponding recessed groove in a frame side for interconnecting two or more adjacent display frames at nearby corners.
