Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 308 words
A modular display device comprising: a base member having extending upwardly therefrom a cylindrical projection having therein axial slots defining inwardly deformable projection portions each having at the upper end thereof an outwardly extending flange; a plurality of modular members stacked vertically above said base member, the lowermost said modular member having therein a central hole of a diameter approximately equal to the outer diameter of said projection, said projection portions being deformable inwardly to enable said lowermost modular member to be assembled onto said base member with said projection extending through said central hole, said projection portions deforming outwardly after said lowermost modular member is assembled onto said base member, said flanges thereafter preventing unintentional removal of said lowermost modular member from said base member; each said modular member having equally circumferentially spaced therearound a plurality of radially outwardly extending arms, each said arm including a bottom wall and two opposite side walls defining a product receiving space, each side wall forming a dihedral angle with the adjacent side wall of the adjacent arm, each pair of side walls defining a dihedral angle being joined at the tops thereof by a triangular element, each said triangular element having a free edge with a notch therein, each said arm having depending downwardly therefrom a tongue element; said tongue elements of each said modular member being received in said notches of the next lower modular member, each said modular member being circumferentially angularly displaced with respect to the next lower modular member, said notches being positioned and dimensioned such that the receipt therein of the tongue elements of the next upper modular member rigidly fixes together the respective said modular members; and an upper member having depending downwardly therefrom a plurality of tongue elements which fit and are received in the notches of the uppermost of said modular members.
Claim 2
Dependent Claim 308 words
A modular display device comprising: a base member having extending upwardly therefrom a cylindrical projection having therein axial slots defining inwardly deformable projection portions each having at the upper end thereof an outwardly extending flange; a plurality of modular members stacked vertically above said base member, the lowermost said modular member having therein a central hole of a diameter approximately equal to the outer diameter of said projection, said projection portions being deformable inwardly to enable said lowermost modular member to be assembled onto said base member with said projection extending through said central hole, said projection portions deforming outwardly after said lowermost modular member is assembled onto said base member, said flanges thereafter preventing unintentional removal of said lowermost modular member from said base member; each said modular member having equally circumferentially spaced therearound a plurality of radially outwardly extending arms, each said arm including a bottom wall and two opposite side walls defining a product receiving space, each side wall forming a dihedral angle with the adjacent side wall of the adjacent arm, each pair of side walls defining a dihedral angle being joined at the tops thereof by a triangular element, each said triangular element having a free edge with a notch therein, each said arm having depending downwardly therefrom a tongue element; said tongue elements of each said modular member being received in said notches of the next lower modular member, each said modular member being circumferentially angularly displaced with respect to the next lower modular member, said notches being positioned and dimensioned such that the receipt therein of the tongue elements of the next upper modular member rigidly fixes together the respective said modular members; and an upper member having depending downwardly therefrom a plurality of tongue elements which fit and are received in the notches of the uppermost of said modular members.
Claim 3
Dependent Claim 25 words
A device as claimed in claim 1, wherein the side walls of each said arm of each said modular member extend parallel to each other.
Claim 4
Dependent Claim 31 words
A device as claimed in claim 1, wherein each said modular member tongue element depends from the respective said bottom wall at a position midway between the respective said side walls.
Claim 5
Dependent Claim 25 words
A device as claimed in claim 1, wherein said upper member includes a plurality of radially extending arms each having depending therefrom a tongue element.
Claim 6
Dependent Claim 23 words
A device as claimed in claim 4, wherein each said upper member arm includes a bottom wall and two opposite non-parallel side walls.
