ABSTRACT:
The invention relates to the guiding and tilting connector at the ends of the slats of a venetian blind which connector includes a flange secured to the end of a slat, a pivot pin extending from the flange longitudinally outwardly of the slat and a pair of guiding and tilting arms extend radially outwardly from the pivot pin. Tilt cords are secured to the outer ends of the arms. The point of connection of the tilting cords to the arms being such that in the closed position of the blind the points of connection between the arms and the tilting cords are offset horizontally with respect to a vertical plane extending through the axes of the pivot pins and also offset from the effective major vertical plane of the slats when in closed position. Because of this offset the weight of the slats in the closed position can exert a moment of force to maintain the slats tightly closed.
