The slats are attached to cords (2,3) fixed to the shaft and the slats are turnably adjustable by rotating the shaft, which is connected to both a hand-operated mecha- nism (9) and automatic drive means (10,16). Said automatic drive means is provided with torque limiting means (13,23). Moreover, a timing device (34-36) is connected to said drive means for all blinds in the group for automatic actuation of all said drive means at determined points of time and setting of the slats in all blinds to closed or open position irrespective of their existing position set by said hand-operated mechanism.
