ABSTRACT:
A motorized blind assembly has top and bottom horizontal end members and a horizontal intermediate blind base member displaceable between the top and bottom members. The ends of a foldable and extensible accordion-like blind are secured, respectively, to the top end member and to the blind base member. An idle pulley is mounted on the bottom end member while a blind drive mechanism is mounted on the top end member; the latter mechanism including a drive friction pulley and a motor assembly able to drive the drive pulley in either of the two directions of rotation. An operating belt winds around the drive and idle pulleys and a mechanism connects the ends of the belt to the base member, this latter mechanism being conceived so that, when the motor assembly is energized, the blind base member moves between the end members causing the blind to fold and unfold. The ends of the belt may alternatively be secured directly to the blind base member.
