VENETIAN BLIND COMPRISING PAIRWISE INTERCONNECTED SLATS

摘要

A venetian blind comprises a plurality of pairs 1 of horizontal slats 3, 5 which are connected together at the ends by means of a rope or tape 15. The Figure shows the venetian blind in partially closed position. The slats can rotate around the longitudinal axis both clockwise and anti-clockwise, so that the top or bottom respectively is rotated to the side facing the window. The venetian blind has cords to which the slats are attached with their longitudinal edges. By pulling at the cords the slats can be rotated clockwise or anti-clockwise.

1. A venetian blind comprising:
a plurality of horizontal slats each having a first horizontal edge and a second horizontal edge; a plurality of vertical cords, of which first cords at spaced apart locations are connected to the first edges of the top slats of each pair, second cords at spaced apart locations are connected to the second edges of the top slats of each pair, third cords at spaced apart locations are connected to the first edges of the bottom slats of each pair, and fourth cords at spaced apart locations are connected to the second edges of the bottom slats of each pair; wherein the top slats of each pair can be rotated in a clockwise direction and in an anti-clockwise direction around their longitudinal axis by pulling up specific cords and releasing other cords, while simultaneously the bottom slats of each pair rotate around their longitudinal axis in an anti-clockwise direction and clockwise direction respectively; and a mechanism by which the cords can be pulled up and/or released, which mechanism is arranged such that the mechanism can immobilize the first and third cords and at the same time can displace the second and fourth cords in mutually opposite directions and vice versa, so that the slats are present between a first position in which the slats of each pair are spaced apart with the first edges and with the second edges are connected to each other, and a second position in which the slats of each pair are connected to each other with the first edges and are spaced apart with the second edges.
