ABSTRACT:
A top down/bottom up covering for an architectural opening is disclosed in a roll-up configuration so the shade can be rolled about a roller in a head rail while having the ability to raise and lower top and bottom rails between which the shade material extends independently of each other. The roller is utilized to raise and lower the bottom rail by wrapping about or unwrapping the shade material from the roller and a control system for raising and lowering the top rail is confined within the roller. The invention is disclosed in embodiments that include a single operating element or a pair of operating elements but in each instance the top and bottom rails are independently movable so the shade material can be extended to any degree between the top and bottom rails and positioned at desired locations within the architectural opening in which the covering is mounted.
