ROLLER SHADE FOR AN ARCHITECTURAL STRUCTURE WITH TOP-DOWN BOTTOM-UP FUNCTIONALITY

摘要

In one aspect, a roller shade includes an upper rail assembly, an intermediate rail assembly suspended from the upper rail assembly via a first suspension element, and a bottom rail assembly suspended from the upper rail assembly via a second suspension element. In addition, the roller shade comprises a shade panel extending between the intermediate and bottom rail assemblies. The shade panel is configured to be wound relative to one of the intermediate rail assembly or the bottom rail assembly as a vertical distance defined between the intermediate and bottom rail assemblies is reduced and unwound relative to the at least one of the intermediate rail assembly or the bottom rail assembly as the vertical distance defined between the intermediate and bottom rail assemblies is increased.
