Abstract
Abstract An interior partition system wherein with relatively few components, most of which can be roll formed from common sets of roller dies, a wide variety of interior screens or full height partitions can be constructed, thus avoiding the necessity of the manufacture and inventory of a large number of parts. For some parts, where volume may not justify the investment in the required roll sets, other manufacturing techniques may be employed, but such parts are readily compatible with the high volume components and usable interchangeably therewith. In the preferred form, a verticaless panel is constructed having a roll formed slotted, recessed edge which includes a double thickness folded flange of special configuration so that adjacent panels may readily be secured together either with a multipurpose co-extruded plastic zipper strip which will provide the desired light and sound seal, accommodate a wide variety of surface finishes and provide an appearance cover for the recessed slots yet providing access thereto for hanging components or accessories to the screen or partition, or a spring metal panel connector.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A panel for a partition system comprising opposite face plates each forming a face and each being bent inwardly at least at one of its vertical edges and, inwardly recessed from the face, then upon itself to form a double thickness vertically outwardly extending flange recessed from the face, the inwardly bent portion then terminating in an also outwardly extending connecting flange parallel to but offset from the face of each said plate, said face plates at their other ends being bent inwardly to define a relatively deep female channel having inturned edge restrictions, and wherein said first and second connecting flanges of one of said face plates abut the corresponding first and second connecting flanges of the other of said face plates.
Claim 2
Dependent Claim
123 words
A panel for a partition system comprising opposite face plates each forming a face and each being bent inwardly at least at one of its vertical edges and, inwardly recessed from the face, then upon itself to form a double thickness vertically outwardly extending flange recessed from the face, the inwardly bent portion then terminating in an also outwardly extending connecting flange parallel to but offset from the face of each said plate, said face plates at their other ends being bent inwardly to define a relatively deep female channel having inturned edge restrictions, and wherein said first and second connecting flanges of one of said face plates abut the corresponding first and second connecting flanges of the other of said face plates.
Claim 3
Dependent Claim
21 words
A panel as set forth in claim 1 wherein said face plates at its other ends are reversely folded upon themselves.
Claim 4
Dependent Claim
123 words
A panel for a partition system comprising opposite face plates each forming a face and each being bent inwardly at least at one of its vertical edges and, inwardly recessed from the face, then upon itself to form a double thickness vertically outwardly extending flange recessed from the face, the inwardly bent portion then terminating in an also outwardly extending connecting flange parallel to but offset from the face of each said plate, said face plates at their other ends being bent inwardly to define a relatively deep female channel having inturned edge restrictions, each of said face plates at its other end being reversely folded upon itself to form a double thickness flange extending substantially in the plane of said face plate.
Claim 5
Dependent Claim
123 words
A panel for a partition system comprising opposite face plates each forming a face and each being bent inwardly at least at one of its vertical edges and, inwardly recessed from the face, then upon itself to form a double thickness vertically outwardly extending flange recessed from the face, the inwardly bent portion then terminating in an also outwardly extending connecting flange parallel to but offset from the face of each said plate, said face plates at their other ends being bent inwardly to define a relatively deep female channel having inturned edge restrictions, each of said face plates at its other end being reversely folded upon itself to form a double thickness flange extending substantially in the plane of said face plate.
Claim 6
Dependent Claim
32 words
A panel as set forth in claim 3 wherein each inwardly bent other end terminates in a second connecting flange extending parallel to but offset from the face of each said plate.
Claim 7
Dependent Claim
29 words
A panel as set forth in claim 3 wherein the inwardly bent other ends of said face plates terminate in inwardly bent terminal flanges which are in overlapped relationship.
