The outside roller can define an elongate slot extending along a length of the outer roller and an aperture of the outer roller toward inside. The inside roller may be received in the outer roller and can define a central vertical shaft. The first shade may be capable of retracting on the outer roller and of extending from the outer roller. The second shade may be capable of extending through the elongate slot and of retracting on the inside roller and extending from the inside roller. The elongate slot may be aligned with the central vertical shaft of the inside roller in a substantially horizontal direction when the first shade is in a fully extended position.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2019,JPO&INPIT
