According to the present invention, the slat turning wheel and the joint interlocking mechanism are used in cooperation to substitute a pull-cord transmission mechanism and a gear transmission mechanism.

Abstract: A louver blind structure comprises a frame with a plurality of louver members pivotally mounted at each longitudinal end thereof to the frame so as to pivot between open and closed positions. An elongated member is movable relative to the frame and is so positioned as to engage the louver members. An actuator is mounted to the frame for selectively imparting a movement to the elongated member. When imparting a movement to the elongated member the louver members engaged thereby are caused to pivot between the open and closed positions. A kit comprising this actuator and the elongate member for a louver blind structure is also provided.
