B _e i an advantageous embodiment of the blind according to the invention, which is provided with at least one relatively heavy-duty bearing block unit for the said set of organs, a winding element and a turning element are rotatably mounted in this bearing block unit, while the upper end of the guide element is directly on or near it Bearing block unit has its point of attack. As a result, the guide element and the elevator element ₃ can achieve this. belonging to this bearing block unit must be placed close together, .ν. According to the invention, the bearing block unit can consist of: a winding element, which - a TJmf angs recess for Burch-: to leave 'an elevator organ except - is coaxially encompassed by a bucket-shaped turning element, while the winding element and the turning element are both mutually rotatable with respect to a zweitgLligen bearing block are stored, who has at the bottom an arm to which the upper end of the;? ührungsor -.- goose from a point _r attacking located under the winding element is "almost vertically - .. sound the elevator institutions and luhrungsOrganen can each time an elevator organ and. a judge organ locally run through a common hole in a blind slat »To give the slats a limited freedom of movement in the transverse direction,

This not only limits the freedom of movement of the slats in the transverse direction, which reduces the risk of noise, but the insert completely or almost completely attenuates the noise, especially if it is made of plastic ""

Its advantageous embodiment is characterized in that a hole provided in the blind slat has a part which is wider than the remaining part of this "hole" and the hand of the insert is provided with a number of facing parts which alternate after the insert has been attached on both sides of the blind slat, whereby the paddling parts on one side have such dimensions that they can be inserted through the wider hole part and the insert that fits into this hole part can be snapped into place and has a locking cam »Sin .. such an insert can be easily installed and is located in the hole; firmly locked a derar- term use satisfied as well as "a aas" a ^warme-: curing or thermoplastic existing _inputs: set, .the means of a "form in the hole appropriate .. is which "form is removed after: the hardening of the plastic".

Both sides of the flanges 40 are on top of the insert 39 flanges 41 and 42 arranged, the verti-. kale distance between the flanges 40 on the one hand and the flanges 41 and 42 on the other hand, the thickness of the lamellas is the same or almost the same. Under part of the flanges 42 is a Crouch 43 is provided, which lies against the edge 44 of the hole 38 / This skirt 43 is slightly beveled, creating a terrestrial, Successful end of the mission in this regard is achieved « In the insert 39 there is an elliptical hole 45 for a guide cable 4 and in the slot 46 for an elevator tape “Die Slots 46 of the superimposed inserts of the ^ 'aio-usielamellen prevent blows from getting into the elevator belts.

The lower ends of the pulling tapes 16 and the supporting tapes 27 and 28 are fastened to the lower beam 2. The lower beam must be of solid construction due to the great weight of the lamellas 3, which means that it is also very heavy. As can be seen from FIG. 1, the support straps 27 and 28 can form loops 47 with the lower beam 2 = as a result, the lower beam 2 will not turn when the lamellas 11en3 are turned. A ^ ichturning the - ^ nterbalkens 2 can, for example, "also be achieved by connecting the lower ends of the support belts with each other and leading this part over ₉ rollers attached in or on the lower beam 2. The lower beam 2 can, as from" -fig- 10 can be seen, assumed a somewhat inclined position, which can be achieved, for example, by attaching the pulling straps outside - the center of the lower beam to this lower beam or by making the lower beam heavier on one side than on the other The guide cables are preferably guided through cylindrical holes in the lower beam.

The support straps 27, 28 can be attached to the slats 3 in numerous ways - I ⁷ Ig. 11 shows a manner of attachment in which a fastener tape. 27 has sleeve-shaped parts .48 through which rod-shaped fastening members or axles 49 run, the middle of the lamellae 3 riveted bearings

± rig "12 shows a number of different, bow-shaped # fastening organs As can be seen from this, the bracket 51 has two legs 52 with bent ends 53? what thighs run through slots in lamella 3. The bracket 51 has one converted part 54 which protrudes outside of the lamella 3.

The bracket 55 differs from the bracket 51 in that the legs 56 wave-shaped or zigzag-shaped are, so that the ends of these legs do not need to be bent.

The bracket 57 is by means of eyelets 58 and ^ ietnägel 59 of the lamella NIIT 3 "connected to the that are available under this sipe blade is a bracket 60 in the _same: ise ¥ _e as: the bracket 57 by means of eyelets 58 and Nietnägel59 fixed" The bracket 60 but have a greater width than the bracket 57V so that when the slats are lying against each other, the bracket 57 can partially grip the bracket 60 »This means that the - ^ amella package does not have an unnecessarily large height when the blind is open»

The bracket 61 has curved legs 62 with converted at right angles Ends that run through slots 63 which run transversely to the Longitudinal direction of the lamella 3 -are attachedo ".

It is clear that all embodiments of the bracket or other fastening elements for the iDragband 27,28 on the slats 3 can be designed in such a way that the fastening
