Claim 10:
11. The roller blind assembly of claim 1, further comprising an outer frame comprising an outer first side, an outer second side, an outer top side, and an outer bottom side, wherein:
the outer first side, the outer second side, the outer top side, and the outer bottom side are connected together respectively to form a modified rectangular shape so that the outer first side extends parallel and congruent in length with the first side of the frame, the outer second side extends parallel and congruent in length with the second side of the frame, and the outer bottom side extends parallel and congruent in length with the bottom side of the frame;
the outer frame is attached to the frame so that the outer first side is adjacent to the first side of the frame, the outer second side is adjacent to the second side of the frame, and the outer bottom side is adjacent to the bottom side of the frame; and
the outer frame at least partially conceals the cylindrical tube when the roller blind assembly is viewed toward a direction in which the outer frame is attached to the frame.
