ABSTRACT:
A Venetian blind has U-shaped mounting rail with lead-in holes for ladder-tapes, cords and slat operating means. The Venetian blind comprises an operating shaft and bearing blocks, bearing bushings hold-down means, a driving device therefor, and a cord lock. These details are designed as snap-in components adapted to be mounted in said mounting rail without necessitating the use of any special mounting means. The operating shaft is non-rotatable relative to and extends through the bearing bushings and is locked against axial displacement, on the one hand by means of an abutment face provided on said hold-down means at one shaft end and, on the other hand, by means of the shaft driving device at the other end of the shaft.
