ABSTRACT:
A vertical blind device with a crank rod for operation, in which slats, which are hung on slat carriages, can be pivoted about a vertical axis by 180.degree. from a closed hanging position, directed horizontally in a plane parallel to one another, into the other closed hanging position and are horizontally movable with the slat carriages in a support rail. A pivot pin of a pivot drive is provided for a pivot shaft, guided through all the slat carriages in an axially displaceable manner and adapted to rotate in unison, and the crank rod have complementary coupling elements. The pivot pin lies with its coupling element in the two stopped positions of the slats laterally outside the plane of the closed hanging. During a reversed rotation, the pivot pin with its coupling element, together with the 180.degree. pivoting movement of the slats, pivots from one side to the other side of the then closed hanging slats.
