A knockdown tray assembly which is capable of supporting heavy loads, using paperboard or cardboard trays and supporting members. The tray supporting members are of a new construction and are formed of inverted U-shaped beams which are provided at the center of each beam with interfitting pivot structure. The interfitting pivot structure is formed by providing a pin in a shallow wall molding on the bottom U-beam and a socket which has a much greater elevation on the upper U-beam, the shallow beam and deep socket improving the stability of the interfitting pivot portion of the beams thereby preventing any unintended disengagement of the pivot and socket element. Also trays are utilized in which the circular openings are ordinarily provided within the corners and at the bottom of each tray to accommodate the circular posts are modified to provide trays which are relatively long. The placement of the circular openings for the sockets is determined by the dimensions of the interfitted U-beams. Thus, each tray has a shelf portion which can extend beyond the posts on each end and thereby adapt the tray assembly for a display tray. Also the display trays in the assembled relationship can be connected to provide a vertical post for supporting a sign at the center of the display.
