ABSTRACT:
A display device of modular construction which preferably is formed of heavy duty paperboard includes a plurality of shelf units (1, 2 and 3) which are adapted for stacking one atop the other and in which each shelf unit comprises a rectangular horizontal platform (4, 27, 49) to the front edges of each of which downwardly extending leg panels (5, 6, 29, 31, 51, 52) are foldably joined, each of which is provided with vertically disposed open ended slits (6, 13, 14, 36, 37, 38, 58, 59 and 60) and to the side edges of each of which upwardly extending leg panels (9, 10, 32, 34, 54, and 55) are foldably joined each of which is provided with vertically disposed open ended slits (17, 18, 19, 20, 42, 43, 44, 45, 62, and 63), apertures (25, 46, 61) being formed in the downwardly extending leg panels for receiving reinforcing bars (24) and the vertically disposed slits in the upwardly extending leg panels of each shelf unit being arranged to cooperate with the vertical slits of the downwardly extending leg panels of associated shelf units above in order to provide a stable and mechanically strong stack of shelf units.
