Abstract
Abstract A hingeless assembly for a modular display panel system is disclosed. The hingeless assembly includes a first portion which allows for attachment thereto of a flat plate wall panel and a second section for attaching an adjacent hingeless assembly thereto. The hingeless assembly of the present invention may be joined to another hingeless assembly with an angle of from zero to ninety degrees therebetween so as to form a display panel system of virtually any shape conceivable. The hingeless assembly attachment portion comprises an extending circular member and an extending parallel arranged cup-like member. The attachment portion of the hingeless assembly allows for connection thereto of another hingeless assembly with the cup-like and circular members of one of the assemblies respectively fitting with the circular member and the cup-like member of the other assembly so as to form a rotatable angle therebetween.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
A hingeless connector assembly for joining one or more similar connector assemblies to form a hingeless post assembly for a modular display system, each connector assembly comprising an elongated member having a first connecting means adapted for attachment thereto of a flat panel and a second connecting means for interlockingly attaching up to four adjoining connector assemblies a plate member between said first and second connecting means said second connecting means comprising a cylindrical member having a substantially circular cross-sectional shape and a groove member having a cup-like cross-sectional shape extending outward from the plate of said connector assembly in a parallel manner with a space therebetween, said cylindrical member in cross section comprising a first portion extending substantially perpendicularly from the plate member a second straight portion connected to said first portion with an angle therebetween and a third portion comprising a circularly-shaped member which is connected to the second straight portion thereof.
Claim 2
Dependent Claim
154 words
A hingeless connector assembly for joining one or more similar connector assemblies to form a hingeless post assembly for a modular display system, each connector assembly comprising an elongated member having a first connecting means adapted for attachment thereto of a flat panel and a second connecting means for interlockingly attaching up to four adjoining connector assemblies a plate member between said first and second connecting means said second connecting means comprising a cylindrical member having a substantially circular cross-sectional shape and a groove member having a cup-like cross-sectional shape extending outward from the plate of said connector assembly in a parallel manner with a space therebetween, said cylindrical member in cross section comprising a first portion extending substantially perpendicularly from the plate member a second straight portion connected to said first portion with an angle therebetween and a third portion comprising a circularly-shaped member which is connected to the second straight portion thereof.
