ABSTRACT:
A novel roller blind structure includes a roller blind made up of a roller shaft, a side winder with a linkage member attached at both ends of the roller shaft respectively to be actuated by an operating member, and a pivoting post respectively protruding at the outer side of the side winder and the linkage member thereof to be mounted to an upper beam thereby wherein, when pulled by the operation member thereof, the side winders and the linkage member will actuate the roller shaft to rotate either clockwise or counterclockwise accordingly so as to control the rolling or unrolling operation of a blind body having an extension piece of a proper length preset at the lower section thereof to be wound backwards and led upwards to be levelly fixed to the inner wall of the upper beam thereof. A counterweight member is retained at the curving turn of the blind body thereof to neatly separate in space the extension piece thereof from a decoration piece disposed at the front section of the blind body thereon. Both the extension piece and the decoration piece of the blind body are respectively equipped with a plurality of light-passable areas alternatively arranged with a plurality of black-out areas disposed at the surface thereon. Via the winding operation of the roller shaft thereof, the blind body can be flexibly adjusted to have it both ways with partial light and partial black-out effect, or to display in a complete black-out status for light control and privacy purpose to achieve best using condition and versatile changes of the present invention.
