ABSTRACT:
A covering for an architectural opening includes a roller assembly having a rotatable roller secured to one edge of a sheet of flexible material with the opposite edge secured thereabove to a fixed location. The roller assembly is cradled in a cord ladder or cord ladder type element so one vertical run of the cord ladder is anchored and the other vertical run is raised or lowered to raise and lower the cradle thereby causing the flexible material to be wrapped around or unwrapped from the roller. The roller assemblies can be used individually or in combination with like roller assemblies and can further be used in combination with other covering products such as sheets of translucent or transparent materials like sheer fabric. In addition to being able to roll and unroll the strips of flexible material onto or from their associated rollers, an entire assemblage of such roller assemblies can be raised or lowered with a closed loop lifting system that raises a bottom rail and accumulates each roller assembly thereabove to any desired degree between a fully extended position and a fully retracted position.
