ABSTRACT:
The present invention pertains to a vertical blind with a crank rod for horizontally displacing and for pivoting the slats, which can each be pivoted by approximately 180.degree. in both directions up to a common plane by a pivoting gear in a slat carriage, which is horizontally movable in a support rail, about a vertical pivoting axis, wherein the crank rod can be coupled with a driving wheel, which is mounted in an end carriage and which is arranged on a pivot shaft, which meshes with a toothed wheel of the pivoting gear in the slat carriage in an axially displaceable manner, but in a manner adapted to rotate in unison. The toothed wheel can be moved about a toothed wheel approximately 180.degree. from one side of the common plane of the slats to the opposite side in a curved guide, which is arranged at the end carriage.
