Venetian blinds

The present innovation relates to a venetian blind with at least two pairs of supporting straps and a large number of slats, whereby elevator tapes are passed through corresponding openings in the slats.

In stores of this type, the openings must be made relatively large so that the Le-Tielle move out of their open position can be turned into the closing division. When closed However, a relatively large amount of light falls through these openings

through into the darkened room, especially in lecture or school rooms is often perceived as annoying.

The present innovation is therefore the task of To design lamellae in such a way that the openings can be kept as small as possible.

According to the innovation, this object is achieved in that each The lamella is longitudinally divided into three zones, that the plane of the middle zone intersects the appearance zones, and that the openings are arranged in the central zone.

Using the enclosed schematic drawing, we J the innovation for example explained. Bs show:

FIG. 3 is a plan view of FIG. 2.

Fig. 1 shows a section from a Rafflamellerstore with a pair of supporting straps 1, 2, an elevator strap 3 and two Slats 4. A Venetian blind has at least two

Pairs of straps and two elevator straps. The slats 4 are Divided lengthways into three zones 41 »42.4 $. the the two outer zones 41 and 43 lie in two parallel lines levels. The middle zone 42 lies in one of the two parallel planes at an acute angle intersecting plane. At the outer end, the slats 4 are each with one Flange 44 is provided, the edge 45 of which is angled inward is. The depth "t" of the Bördeis is greater than his , Height "h". The straps 1 and 2 is opposite An opening 46 is arranged in the flange. In the middle zone 42, the lamellae are provided with openings 47 through which the elevator tape 3 is passed. Through the opening 45 is, as from the Pig. 2 and 3 shown

lich, a body 5 pushed. At its leading end, the body 5 has a groove 6 in which the angled edge 45 of the flange 44 engages. The body 5 is made of plastic and is molded onto the carrier tape 2, which in the illustrated case is designed as a carrier cord, and is thus firmly connected to it. When assembling a Venetian blind of the type described, it is possible to connect the strings 1 and 2 to the slats by inserting the body 5 into the openings 46, whereby the flanged edge 45 latches with the edge 6 of the body 5 45 with the groove 6 is the
