A vertically folding wall partition comprising: a set of foldable panel assemblies serially and pivotally connected through a series of vertically spaced apart supports (62, 64), an uppermost of the panel assemblies having a top end pivotally connected to a hanger for engagement to an overhead structure, each panel assembly including an upper panel and a lower panel pivotally connected to one another, the upper and lower panels extending substantially in a common vertical plane when in a deployed position and extending laterally outwardly of said common vertical plane in an opposed surface-to-surface stacked relationship when in a folded position, wherein a lowermost of the panel assemblies has a bottom end pivotally connected to a bottom linkage; and a moving mechanism of the vertically folding wall partition engages each support (62, 64) and the bottom linkage to sequentially move the panel assemblies between the folded and deployed positions, the moving mechanism varying a distance between opposed ends of each panel assembly following a downwardly progressing sequence starting with the uppermost panel assembly as the panel assemblies are moved from the deployed position to the folded position, and the moving mechanism varying the distance between the opposed ends of each panel assembly following an upwardly progressing sequence starting with the lowermost of the panel assemblies as the panel assemblies are moved from the folded position to the deployed position, wherein the moving mechanism includes a support pulley (72a, 72b) retained on each support (62, 64) and a plurality of hanger pulleys (106a, 106b, 106c) retained on the hanger, each pulley being rotatable about a respective horizontal axis; a cable having a first end connected to the bottom linkage and extending directly to engagement with one of the hanger pulleys (106a, 106b, 106c), and a motor operatively connected to a second end of the cable to selectively apply tension thereto and release tension therefrom characterized in that the cable, after extending directly to engagement with one of the hanger pulleys (106a, 106b, 106c), extends in engagement with each support pulley (72a, 72b) in alternation with a corresponding one of the hanger pulleys and ending with one of the hanger pulleys, the support pulleys being engaged following an upwardly progressing sequence starting at a lowermost of the support pulleys. a set of foldable panel assemblies serially and pivotally connected through a series of vertically spaced apart supports (62, 64), an uppermost of the panel assemblies having a top end pivotally connected to a hanger for engagement to an overhead structure, each panel assembly including an upper panel and a lower panel pivotally connected to one another, the upper and lower panels extending substantially in a common vertical plane when in a deployed position and extending laterally outwardly of said common vertical plane in an opposed surface-to-surface stacked relationship when in a folded position, wherein a lowermost of the panel assemblies has a bottom end pivotally connected to a bottom linkage; and a moving mechanism of the vertically folding wall partition engages each support (62, 64) and the bottom linkage to sequentially move the panel assemblies between the folded and deployed positions, the moving mechanism varying a distance between opposed ends of each panel assembly following a downwardly progressing sequence starting with the uppermost panel assembly as the panel assemblies are moved from the deployed position to the folded position, and the moving mechanism varying the distance between the opposed ends of each panel assembly following an upwardly progressing sequence starting with the lowermost of the panel assemblies as the panel assemblies are moved from the folded position to the deployed position, wherein the moving mechanism includes a support pulley (72a, 72b) retained on each support (62, 64) and a plurality of hanger pulleys (106a, 106b, 106c) retained on the hanger, each pulley being rotatable about a respective horizontal axis; a cable having a first end connected to the bottom linkage and extending directly to engagement with one of the hanger pulleys (106a, 106b, 106c), and a motor operatively connected to a second end of the cable to selectively apply tension thereto and release tension therefrom characterized in that the cable, after extending directly to engagement with one of the hanger pulleys (106a, 106b, 106c), extends in engagement with each support pulley (72a, 72b) in alternation with a corresponding one of the hanger pulleys and ending with one of the hanger pulleys, the support pulleys being engaged following an upwardly progressing sequence starting at a lowermost of the support pulleys.
