ABSTRACT:
A modular display device includes a base member, the upper part of which has a projection which extends into a center hole in the lowermost of a plurality of identical vertically stacked modular members, each of which has a plurality of radially extending arms, each of which includes parallel opposite side walls, each of which is joined at an upper part thereof, to the adjacent wall of the adjoining arm, with which it forms a dihedral angle, by means of a triangular shaped element, the free side of which has a notch. The notches receive tongue elements of the next upper modular member, thereby attaching one modular member to another. The assembly is finished off at the top with an upper member the lower part of which is provided with tongues to be coupled to the upper part of the uppermost modular member.
