A venetian blind comprises at least two spaced apart support cables and a plurality of slats disposed at spaced locations along the support cables and having respective front and rear edges which are respectively engaged for relative rotation on coupling heads for each edge of the slats mounted on the respective cables in pairs at spaced locations along the lengths thereof. The coupling head also has cable-engagement means in the form of a supporting ring which connects the coupling to the cable in a manner permitting relative rotation therebetween about an axis which is substantially at right angles to the axis of the pivoting of the slats. The construction includes fold-initiating means which are associated with the cables between the coupling heads and which are effective to fold the cables in a preselected fold intermediate the lengths of the cables between the coupling head. |
