Abstract: A support device (1) for a curtain (2), in particular for room with at least a floor (P) and a wall (4) in relation to which the curtain (2) is hung, comprising at least one guide element (5) along which slides at least one mechanism (10) for raising the curtain (2) and designed to guide the movement of a corresponding cord (11) or the like connects to a free end of the said curtain, said movement permitting said end to be raised from the floor parallel to the said wall. The said device (1) comprises means of control (40, 50) that determine the movement of the cord or the like with respect to the raising mechanism (10) and the sliding movement of the latter along the guide element (5). Said movements of the cord and raising mechanism occur in two mutually orthogonal directions.
