Abstract
A shade system includes a plurality of shade assemblies each including an elongated shade tube having an inner surface defining an inner cavity, an outer surface for winding receipt of a flexible shade, at least one coupling end, and an axis of rotation; a connector assembly having a first coupling unit secured to the inner surface at the coupling end of a first shade tube and a second coupling unit secured to the inner surface at the coupling end of a second shade tube substantially adjacent the first shade tube, the first coupling unit and the second coupling unit cooperating to transfer an applied torque from the first shade tube to the second shade tube; an end bracket for rotatably supporting a free end portion of a shade tube when attached to a supporting structure; and a mounting bracket for adjusting the connector assembly.
