Abstract (en)
[origin: WO2012150946A2] Cord tensioning systems are provided for top down/bottom up coverings to prevent entanglement of lift cords about associated wrap spools by correlating rotation of the wrap spools with translating threaded nuts mounted on threaded shafts rotating in unison with the wrap spools whereby abutment of nuts associated with lift spools prevent over movement of rails associated with the spools and thus entanglement of the lift cords associated therewith.
