Abstract

A window covering is disclosed that has a first rail (1), a double spool (4) connected to the first rail (1), at least one motor (13) connected to the first rail (1), and window covering material (2) extending from the first rail (1). A plurality of primary lift cords (9) extends from the first spool portion (22) of the double spool (4) and is connected to the window covering material (2) such that rotation of the double spool (4) in a first direction extends the window covering material (2) away from the first rail (1) and rotation of the double spool (4) in an opposite second direction retracts the window covering material (2) toward the first rail (1). One or more secondary cords (11) extend from the second spool portion (22) of the double spool (4) and are connected to the one or more motors (13).
