<p>The invention relates to a window shade (5) or a screen that are unrolled with the aid of actuating elements (14, 15), whereby the actuating elements (14, 15) pivot about an arbor situated at a right angle to the roller shaft (18), on which the accompanying shades or screens (8) are rolled up. The actuating elements (14, 15) are rigid with regard to a bending plane, which is perpendicular to planes defined by the extended shade (8) or screen. An angular gearing mechanism (22, 23) is provided for each of the actuating elements (14, 15), and the output shaft of the angular gearing mechanism supports the respective actuating element (14, 15) in a rotationally fixed manner. The output shaft (32, 34) of the respective angular gearing mechanism (22, 23) simultaneously forms the arbor for mounting the actuating elements (14, 15).</p> |
