A vertical blind construction, including slats arranged hanging on a slat carriage each, tiltably around a vertical axis, and with a driving element (1), whose direction of movement is reversible, or a gear, which can be connected by coupling elements to an endless pull cord (6) for laterally displacing the slat carriages guided in a support rail (31), and to a grooved shaft (11), which passes through a tilting gear for tilting the slats in the slat carriages. The rotatable driving element (1) in connection with a planetary gear, wherein the driving element (1) is connected to the central gear (2), whose outer ring (4) is connected by a first recording disk idling gear (5), whose idle is adjusted to a slat tilt angle of 180°, to a drive gear (7) or the pull cord (6) and, via an intermediate gear (10) as well as a slip clutch (13), to the grooved shaft (11). The slip clutch (13) is associated with a second recording disk idling gear (12) for a slat tilt angle which likewise corresponds to 180°, which second recording disk idling gear opens, at the end of its idle running, the slip clutch (13), and the first recording disk idling gear (5) disengages, at the end of its idle running, against the action of a spring, a movably guided shifting element (17), which blocks the rotation of the drive gear (7) for the pull cord (6).
