A roller blind structure of the kind comprising an elongated tubular member, having secured thereto one end of a fabric web and being rotatably mounted in elongated openings in two spaced apart brackets so as to allow said tubular member to be also displaced towards and away from a window or the like and further having a flanged reel secured to said elongated member and a cord which has one end thereof secured to said reel and wound up in a direction opposite to the winding direction of the web. A cover with elongated upper and lower walls is provided to form an elongated recess for receiving the flanged reel in a manner to allow it to be displaced with the tubular member. The cover further has in the lower wall thereof an elongated opening permitting the passage of the cord in a substantially vertical direction independent of the actual displacement position of the reel. The elongated opening may have a widened portion where the cord passes when the tubular member is in its innermost position and may either be integral with one of the brackets or made as a separate part, which can be detachably connected to said bracket. |
