Lanellenstore

The present invention relates to a blind with a large number of parts that can be moved relative to one another.

By handling the previously known Lar.elbnstores there is usually a not inconsiderable noise caused by clashing the mutually movable parts is caused.

The present invention now wants this undesirable one Avoid larment jickluntJ and create a quiet store.

According to the invention this is achieved in that the one Parts made of a material with a low intestinal capacity and the others at least partly consist of a material with a great dampening capacity, and that in every position of the slatted blind the parts with a low heat absorption capability only touch those with an exuded ability to dampen "

Embodiments of the subjects of the invention3 are on Hand of the drawings explained in more detail, namely show:

Fig.l shows a detail of a vertical cross section through a roller blind door in the unwound and half-open state;

FIG. 2 shows a detail from FIG. 1 on a larger scale; 3 shows a section along the line III-III of Fig.l and Fig. 4-7 Details of variants

The store has a large number of slats 1 which are attached to the pull-up shaft by means of several tension straps, in a VJeise known per se 9 are hung. The lamellas 1 consist, for example, of light metal sheet and have a profile that is slightly curved outwards with an inner and an outer, inwardly curved longitudinal edge. Are the lamellae 1 frontal? on one guide belt each 3 made of rustproof steel, rotatably mounted. For this purpose, a guide pin 4 is riveted to each end edge of the lamella 1. According to FIG. 3, the guide pin 4 is made of plastic, for example consists in an eyelet 5 attached to the guide band 3 and rotatably mounted. The arrangement is so made that there is no play in the direction of the strap between the eyelet and the bolt. The eyelet encompasses the bolt in the area of a screwed in Bolt section.

The two guide strips 3 running laterally of the slats are guided in lateral, U-shaped guide rails 6.

The two ^{legs of the guide rails 6 facing each other 1} each have on their inner side a longitudinally extending, swiveling, eccentric mute. In this actual iluten each a thin, elastic band 8, for example made of plastic or steel, is clamped, which as shown in Fig. 3 _f apparent inwardly bulged and that deliver both serve to guide the Lamellenpanzars, ^T -se as geräus chdänpf end Act intermediate layer.

Are at the 9 Aufziehwalle several Zuqbindar 2 attached to which the slats 1 with their longitudinal edges innenliegendsn Toggle A are steered. As can be seen from FIG. 2, the lamella 1 is cut out below the beaded edge at the articulation point, with a slotted eyelet 10 made of noise-dampening material, for example plastic, the air. The drawstring is attached by means of claws 11, extends through the ^ usnehmun ^ 17 and completely surrounds the beaded edge.

When the lamellar shutter is closed, the outer one is located Longitudinal edge of the lamella on the back of the next lower lamella and can thereby, especially when exposed to wind, to noise

i lead development. To prevent this, the entire lower part of the longitudinal edge is covered with a covering made of flake-like, noise-dampening material, for example plastic. This flake-like covering 13 is applied as follows: At the stalls where the flake-like covering is to be applied, the lacquer layer is first cleaned and provided with a suitable binding agent, which aims to soften the lacquer layer present on the lamellas and to create an adhesion between the

9099-43 »Λ1 111

Lacquer layer and the flake-like, electrostatically applied coating. According to deir. Once the flaky coating has been applied, the binder is cured and neutralized by a thermal treatment. The binding agent can consist of the same stoving lacquer that was already used for the lamellar profile when the Li ichtalIbandes was lacquered and of an additive to dissolve the stoved lacquer layer. As a modification of the arrangement shown in FIG Noise reduction

• in
A U-shaped, thin-walled profile, for example an aezocrene plastic profile, can be inserted into the U-shaped guide rail 6, as can be seen from FIG. In order to prevent the guide band or the joints from coming into contact with the Filhrun ^ sschiene 6, the guide band could also be provided with plastic pins 15, as can be seen from FIG. These pins can consist of one piece or consist of two push-button-like parts connected to one another. As a further variant to the variants already listed above, the guide rail 6 could be completely lined on the inside with rubber-like material or plastic.

To between the to achieve noise damping of the next lower lamella, spacers 16 arranged on the tension band, for example

made of plastic, be provided (Fig. 4), the aLne contact of the longitudinal edge of the upper lamella with the back of the lower w La * £ "ll *" prevent the store from being closed.

As can be seen from de * Pig .5 , however, a further variant of the door-protruding, bent, outer longitudinal edge of the lamella could be a noise-reducing band 18, for example made of plastic, which extends along the edge of the lamella and which, with its, one The end of the L-long edge is demined. This band is bent downwards and forwards around the longitudinal edge of the lamella, its area at the point of contact between the adjacent lamellae being at a certain distance from the longitudinal edge.

The outer longitudinal edge of the lamellas does not necessarily have to move untan but can also be bent upwards.
