ABSTRACT:
The invention relates to slats (1) for a venetian blind comprising slats of very large dimensions, both relating to the width of the slats and to the longitudinal extension of the slats (1). Thus the venetian blind comprising these slats can be made to cover very large window openings or other parts of buildings and rooms. The slats (1) are provided with longitudinal edge portions (3) serving the dual purpose of increasing the overall rigidity of the slats (1) and of providing attachment means (12) for support cords of the slats (1). The slats are operated by pairs (typically two) of lift and tilt cords running in parallel along the longitudinal edges of the slats (1), thereby avoiding passages through the slats (1), which is advantageous both from an aestetical point of view and from the point of view of the necessary production technique for the slats (1). The invention also relates to releasable attachment means (12) for connection the slats (1) to the tilt cords of the venetian blind. The Invention furthermore relates to the venetian blind as such comprising the above slats (1) and attachment means (12), and due to these is becomes possible to assemble the complete venetian blind in situ in a very easy manner. Also the removal and replacement of individual slats (1) without the necessity to dismantle major portions of the venetian blind is greatly facilitated according to the invention. Finally the invention also relates to a lift- and tilt mechanism for controlling tilting and raising/lowering of the slats (1).
