Abstract: A vertical blind assembly of the type comprising a plurality of vertically oriented slats or blinds depending from a supporting header structure movable both along the length thereof, as well as each being rotatable about their individual longitudinal axis. A carrier assembly is structured to accomplish rotation of a carrier element removably supporting each of the slats by rotation of a drive rod through the structural design and relative disposition of intermeshing gears, a first of which is interconnected to rotate with the drive rod and a second of which is interconnected to rotate with the carrier element.
