Abstract: A lateral pull roll-up blind includes a drive housing member which is provided with lateral connecting elements which are situated within the outline of the driving wheel. These connecting elements, as well as compatible connecting elements of a carrier are distributed along a distribution circle in a distributing pattern rendering multiple angular repositioning of the housing member relative to the carrier possible. Even the other end of the lateral pull roll-up blind and the corresponding carrier are constructed in the same manner. The housing member is provided with a hollow pin on which there is mounted a clamping winding spring, while an entraining disc serving for the rotational entrainment of the associated end of the take-up shaft is rotatably mounted in the pin of the housing member. The entraining disc is drivingly connected with the driving wheel through actuating portions of the clamping winding spring.

Abstract: One end of the retraction spring of a lateral-traction roller shade is fastened to an interior rod that is stationary once it has been installed. The other end of the spring is fastened to a carrier bushing that rotates on the interior rod. The shaft of the shade is attached to the bushing and one end of a retention and clamping spring that surrounds the rod is fastened inside the bushing in such a way that the spring will rotate along with it. The other end of the spring is positioned in the path traveled by a drive segment on a sheave when the shade is lowered and in front of a drive rib on the bushing that is also positioned in the path. The raising of the shade is thus facilitated by the retraction spring.
