Abstract
Abstract A powerized partition which may be shifted from a collapsed storage position to an extended, wall-defining position. The wall structure provided by the extended panel is nonlinear, being in the form of an L or similar configuration. The panel assembly is provided with powerized drive means for extending and collapsing the same.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A powerized folding partition comprising a suspension track assembly including a first section, a second section and a curved transition section interposed between said first and second sections, a plurality of hingedly connected panel members mounted on said track assembly for translatory movement from a stacked position at a stacking zone adjacent the end of said first section to an extended, partition-defining position wherein said panels are arranged in edge-to-edge alignment along said track assembly, main drive means including a cable aligned with said track assembly and connected to the lead panel for shifting said lead panel along said assembly between said stacked and said extended positions, and independently powerized auxiliary drive means operatively associated with at least one selected panel between said curved section and stacking zone in the extended position of said panel members, urging said selected panel toward said zone.
Claim 2
Dependent Claim
143 words
A powerized folding partition comprising a suspension track assembly including a first section, a second section and a curved transition section interposed between said first and second sections, a plurality of hingedly connected panel members mounted on said track assembly for translatory movement from a stacked position at a stacking zone adjacent the end of said first section to an extended, partition-defining position wherein said panels are arranged in edge-to-edge alignment along said track assembly, main drive means including a cable aligned with said track assembly and connected to the lead panel for shifting said lead panel along said assembly between said stacked and said extended positions, and independently powerized auxiliary drive means operatively associated with at least one selected panel between said curved section and stacking zone in the extended position of said panel members, urging said selected panel toward said zone.
Claim 3
Dependent Claim
29 words
A device in accordance with claim 1 wherein said auxiliary drive means comprises a cable connected to said selected panel and arrayed in substantial alignment with said first section.
Claim 4
Dependent Claim
14 words
A device in accordance with claim 2 wherein said cable is under constant tension.
Claim 5
Dependent Claim
21 words
A device in accordance with claim 3 wherein said auxiliary drive means includes a negator spring motor applying said constant tension.
Claim 6
Dependent Claim
40 words
A device in accordance with claim 1 and including guide means along said first section interposed between said curved section and said stacking zone for limiting folding movement of said panels in advance of said panels reaching said stacking zone.
Claim 7
Dependent Claim
145 words
A powerized folding partition comprising a suspension track assembly including a first section, a second section and a curved transition section interposed between said first and second sections, a plurality of hingedly connected panel members mounted on said track assembly for translatory movement from a stacked position at a stacking zone adjacent the end of said first section to an extended, partition-defining position wherein said panels are arranged in edge-to-edge alignment along said track assembly, main drive means operatively connected to the lead panel for alternatively pulling said lead panel from the stacked to the extended position and pushing said lead door from the extended to the stacked position, and auxiliary tension means engaging at least one panel which, in the extended condition of said partition, is disposed between said curve section and said stacking zone, for yieldingly urging said one panel toward said zone.
Claim 8
Dependent Claim
145 words
A powerized folding partition comprising a suspension track assembly including a first section, a second section and a curved transition section interposed between said first and second sections, a plurality of hingedly connected panel members mounted on said track assembly for translatory movement from a stacked position at a stacking zone adjacent the end of said first section to an extended, partition-defining position wherein said panels are arranged in edge-to-edge alignment along said track assembly, main drive means operatively connected to the lead panel for alternatively pulling said lead panel from the stacked to the extended position and pushing said lead door from the extended to the stacked position, and auxiliary tension means engaging at least one panel which, in the extended condition of said partition, is disposed between said curve section and said stacking zone, for yieldingly urging said one panel toward said zone.
Claim 9
Dependent Claim
44 words
A device in accordance with claim 6 wherein a plurality of the panels which, in the extended condition, are disposed between said curved sections and stacking zone, are provided with individual tension means for yieldably urging the panels of said plurality toward said zone.
Claim 10
Dependent Claim
29 words
A device in accordance with claim 7 wherein the combined force of said tension means is sufficient to advance said panels on said first section toward said stack zone.
