Abstract
Abstract A flexible multi-panel system for use as exhibits, partitions or backdrops in tradeshow, convention, or other such displays is presented. The system includes a flexible panel having a plurality of individual, longitudinal members or segments flexibly interconnected to one another. The panel is capable of being formed into straight, angled and/or curved configurations and includes devices for locking the panel in such desired angular configurations. This locking is accomplished by grooves which are provided at the top and/or bottom of each of the individual flexibly interconnected members. The grooves accept locking devices for rigidizing adjacent segments of the panel into a desired shape. Preferably, a textured carpeting or similar decorative covering material is provided on the outside of each of the longitudinal members with the decorative carpeting acting as the flexible interconnect or hinge between each member. Suitable panel interconnects are provided along the end members of each panel for interlocking one panel with another panel. Preferably, the individual members or segments are comprised of a lightweight material such as a honeycomb plastic or cardboard. At least one of the longitudinal members may be provided with a conduit for accepting electrical wiring.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
218 words
A flexible panel comprising: a plurality of adjacent longitudinal members, each member including a core having top and bottom portions, said cores having a flexible outer covering thereon, said outer covering interconnecting at least two of said adjacent longitudinal members to define a flexible hinge between said two adjacent members; a groove in at least one of said top and bottom portions of said cores defining at least a pair of grooves, said grooves having a preselected width and being respectively aligned in said two adjacent longitudinal members to define a continuous uninterrupted groove between said two adjacent longitudinal members; means for locking said flexibly connected adjacent members in a preselected angular configuration, said means for locking comprising a rigid flattened insert which is insertable in said continuous uninterrupted groove of said two adjacent longitudinal members to thereby lock said members in said preselected angular configuration, said rigid insert having a preselected angle corresponding to the preselected configuration desired between said two adjacent members, said preselected groove width adapted for receiving said rigid insert; and said rigid flattened insert having a thickness dimension which is small relative to the width and length dimensions thereof, said thickness dimension of said insert forming a friction fit with said preselected width of said grooves to thereby lock said adjacent longitudinal members.
Claim 2
Dependent Claim
218 words
A flexible panel comprising: a plurality of adjacent longitudinal members, each member including a core having top and bottom portions, said cores having a flexible outer covering thereon, said outer covering interconnecting at least two of said adjacent longitudinal members to define a flexible hinge between said two adjacent members; a groove in at least one of said top and bottom portions of said cores defining at least a pair of grooves, said grooves having a preselected width and being respectively aligned in said two adjacent longitudinal members to define a continuous uninterrupted groove between said two adjacent longitudinal members; means for locking said flexibly connected adjacent members in a preselected angular configuration, said means for locking comprising a rigid flattened insert which is insertable in said continuous uninterrupted groove of said two adjacent longitudinal members to thereby lock said members in said preselected angular configuration, said rigid insert having a preselected angle corresponding to the preselected configuration desired between said two adjacent members, said preselected groove width adapted for receiving said rigid insert; and said rigid flattened insert having a thickness dimension which is small relative to the width and length dimensions thereof, said thickness dimension of said insert forming a friction fit with said preselected width of said grooves to thereby lock said adjacent longitudinal members.
Claim 3
Dependent Claim
67 words
