Definitions
- a slatted roller blind consists of a large number of parallel slats that are parallel to each other and generally horizontal.
- the lamellae are curved in a cylinder shape around an axis running parallel to the lamella axis in order to obtain sufficient buckling stability.
- the individual slats are kept at a distance from one another, with a light gap being formed between adjacent slats.
- the spacers for the slats are rope-like structures on whose rungs the slats rest. With the help of two bands running through all the slats, the length of the slatted blind can be varied. The entry of light can also be varied by more or less sloping the slats.
- the object of the invention is to create a new type of fabric.
- a planar structure is to be created in which the passage of light to be observed through reflections in the planar structure is further reduced.
- the new type of flat structure consists of a large number of parallel bars which are connected to one another by connecting means, in such a way that at least in the position of use, there is a gap between adjacent bars.
- the connecting means also allow the sheet to be flexible about axes that are parallel to the bars.
- the new type of fabric can thus be used both as a material for window blinds, awnings and the like, i.e. to regulate the passage of light, and as wall or ceiling cladding, especially to influence the room acoustics. Due to the gap between see the bars, the sound absorption in the room can be influenced.
- the connecting means can be formed by at least two at least approximately linear or band-shaped connecting elements, via which the individual rods are connected to one another to form a flat structure.
- the linear connecting means can either run through openings in the rods or they can extend over the outer peripheral surface of the rods and be connected to the outer peripheral surface.
- connection point which are twisted together in the area of the gap.
- connection means consists in the use of individual links, which only connect two rods to each other. Their shape depends on the type of rods concerned.
- the rods of the fabric are preferably predominantly hollow.
- the rods have a constant cross section over their length.
- the rods can have the shape of tubes which are completely closed in the circumferential direction or they can be designed as tube-like structures which contain a gap running along their length on one side.
- the use of the gap significantly simplifies production.
- individual fasteners these are provided with a shaft and a head, the head resting against the slot edges and the shaft leading outward through the gap.
- the shaft dips into a corresponding opening in the adjacent rod and is anchored in this opening.
- the simplest form of anchoring is to bend the shaft 90 ° in the next rod.
- the rods of the fabric are preferably produced by roll forming, which makes it particularly easy to produce rods with a longitudinal slot, in fact endlessly.
- the rods expediently consist of a material which does not oxidize in the atmosphere in question, e.g. made of aluminum or stainless steel, preferably with a satin surface.
- the wall thickness of the bars is between 0.1 and 0.5 mm, preferably between 0.2 and 0.4 mm. The latter is a good compromise between weight, deformability during roll forming and stability during later use.
- Plastic is also an option, whereby the connection technology is based on the material, the weight and the resulting force at the most stressed point.
- the rods preferably have an essentially elliptical or kidney-shaped shape, because in this way a good shading effect is still possible even when the sun is low, without the rods having to be arranged too closely next to one another.
- the diameter of the rods can be between 2 mm and 15 mm, preferably between 2 and 5 mm.
- the distance is between 0.5 and 5 mm.
- the wall thickness of the bars is between 0.1 mm and 0.5 mm.
- the rods are straight to allow them to be rolled up on a winding shaft, but they can also be curved.
- Securing means prevent the bars from being displaceable relative to one another in the longitudinal direction.
- spacer elements in the form of short pipe sections can be used, or the spacer elements are an integral part of the rods or the connecting elements.
- this steel wire is bent in a zigzag shape, with a rod being arranged at each kink.
- the linear connecting means can be monofilaments made of plastic or metal, preferably spring steel.
- the connecting elements should expediently be UV-resistant and also not oxidize.
- the distance between the bars can vary along the length of the fabric, that is to say in the direction transverse to the longitudinal extension of the rods, be constant or vary in this direction.
- the variation can take place in sections or continuously.
- a very bright, glowing, almost dazzling strip may be observed, which has the width of the light source and extends over the entire vertical or horizontal extent of the fabric spreads.
- the direction of propagation of the light stripe depends on whether the bars are arranged horizontally or vertically. With horizontal bars, a vertical stripe is created.
- the rods form a tube which is closed in the circumferential direction.
- the bars have the same cross-sectional profile. It is designed in such a way that each rod forms a continuous channel on its outside, that is to say on the side which is the reverse of the light source.
- the channel points upwards at an angle of approx. 26 ° with respect to a plane defined by the flat structure.
- the channel is delimited by two essentially flat surfaces, which enclose an angle between 165 ° and 120 °, preferably an angle of 137 °.
- the direction of the channel means that the bisector between the two surfaces that delimit the channel runs at an angle of approximately 26 ° with respect to a plane that is defined by the stretched-out flat structure.
- two edges of the cross-sectional profile can run parallel to one another.
- An edge extending between the mutually parallel edges encloses an angle of 86 ° with the longer of the two mutually parallel edges.
- the orientation is chosen so that the front edge of the rod faces the light source, is slightly higher than that edge of the rod that lies away from the light source.
- a particularly simple manufacture results if the rod is roll-rolled from a sheet metal strip.
- the rolled profile can be designed to overlap on one side. On the one hand, this has the advantage of an improved visual impression and, on the other hand, with a corresponding position of the overlap, a defined, sharp result Edge in the area of the underside of the rod in question and thus more favorable conditions when radiating in the sense of a better shadow effect.
- laser welding can also be used, which is very simple in production technology because threading processes are avoided.
- the pentagonal profile is essential for laser welding because a flat surface is available.

- a roller blind web 4 is fastened with an edge, which is drawn coarsely.
- the roller blind 4 consists of a textile fabric 5, as shown in a schematic representation in FIG. 2.
- the flat structure 5 is composed of a plurality of rods 6 running parallel to one another together, which extend over the width of the fabric 5 and are spaced apart. The distance between the bars is approximately as large as the diameter of each bar 6.
- Each rod 6 consists of a circular stainless steel tube which is closed in the circumferential direction.
- a plastic tube or a drawn aluminum tube can also be used, or it is possible to produce the rods 6 by roll forming, as will be shown below.
- Brass or bronze can also be used as the material.
- the surface of the rods 6 can be satin or glossy, depending on which optical effect is to be achieved.
- connecting means are required
- Each of the connecting means 7 consists of a connecting element 8 in the form of, for example, a stainless steel wire with a small diameter.
- each rod 6 is provided with holes 9 aligned with one another at the relevant point.
- the axes of the bores 9 lie at right angles to the longitudinal axis of the rods 6 and pass through the respective rod 6 on a diameter. Since the connecting elements 8 lie in a common plane when the sheet-like structure 5 is spread out, all of the bores on the rods 6 are also aligned accordingly, ie the bores 9 on each rod 6 are axially parallel.
- the connecting element 8 in the form of the stainless steel wire, passes uncut through one after the other through all the rods 6, ie the connecting element 8 extends over the entire length of the flat structure 5.
- the rods 6 lying on the edge of the flat structure 5 are connected to the connecting element 8, for example by welding, Glue or deform anchored in a suitable manner.
- a spacer sleeve 11 is threaded onto each connecting element 8 between two adjacent rods.
- the spacer sleeves 11 all have the same dimensions, as a result of which the parallel of the rods 6 is kept at a distance and also, based on the longitudinal direction of the flat structure 5, all of the rods 6 are at the same distance from one another. In this way, the desired gaps between the bars 6 are achieved.
- the diameter of the bars 6 and the size of the gap between them are adapted to the particular application and is preferably between 2 and 15 mm, preferably between 2 and 5 mm, while the distance is of the same order of magnitude.
- the wall thickness of the rods is 0.1 to 0.5 mm, preferably 0.2 to 0.4 mm.
- each rod 6 consists of a stainless steel sheet strip roll-formed into a tube.
- the cross section of the rod 6 is approximately elliptical or oval.
- the tube produced by roll forming is not closed on the circumference, but instead has on one side with a smaller radius of curvature a slot 12 which extends over the length and is delimited by two slot edges 13.
- the slot edges 13 extend parallel over the length of the rod 6 at a constant distance. They are at the same height, ie the bar has no crack in the area of the slot 12.
- each rod is provided with a series of holes 14, the number of which corresponds to the number of desired connecting elements which are provided along the rod 6 and which are diametrically opposite the slot 12.
- Each connecting element 8 has the shape of a “nail” and consists of a wire-shaped shaft 15, which is provided at one end with a head 16. At a point remote from the head 16, the shaft 15 is bent at a right angle at 17, so that a longer section 18 of the shaft 15 extends in the direction parallel to the longitudinal extent of the bar 6.
- the length of the section 18 is greater than it corresponds to the inside width of the bar 6.
- the section 18 has a length corresponding to about two to three times the diameter of the rod 6.
- the head 16 rests on the side of the two slot edges 13 facing the interior when the sheet-like structure 5 is suspended, while the angled section 18 bears against the inside of the rod on the side opposite the slot 12.
- the manufacturing process of the fabric 5 according to FIGS. 3 and 4 can look as follows:
- the section 18 When threading, the section 18 can protrude freely through the slot 12 on the opposite side, so that the connecting element 8 can be inserted until the bending point 16 is in the hole 9.
- the connecting element 8 is then rotated through 90 ° until the section of the shaft 15 with the head 16 located thereon protrudes at a right angle from the rod 6.
- a filler piece can be temporarily inserted into the rod 6 in question, by means of which the angled section 18 is held against the inside of the rod 6 for contact.
- the filler itself is again rod-shaped and can therefore be inserted easily because, for example, all the connecting elements 8 are threaded into the relevant rod 6 with the same orientation of the angled section 18.
- the Rod 6 prepared in this form is connected to a further rod 6 by inserting the connecting elements 8 into the slot 12 of this further rod 6, their head 16 being located inside the rod 6 concerned.
- the filler piece which serves to temporarily fix the sections 18, is then pulled out again.
- a corresponding end piece can be inserted into each of the rods 6 for laterally locking the rods against one another.
- the end piece prevents the head 16 of the connecting element 8 present at the end from slipping out of the relevant rod 6.
- Figures 1 and 2 show a flat structure 5, in which the connecting elements 8 do not have the shape of a bent "nail", as in the embodiment of Figures 3 and 5, but a U-shape.
- Each connecting element 8 consists of a bent wire section which forms a back 19. At both ends, the back 19 merges into two arches 20, which are directed away from the open side of the U-shaped connecting element, as shown.
- the back 19 merges into two legs 21 which are axially parallel to one another and are bent to opposite sides at their free ends, as can be seen in FIG. 5. This results in laterally projecting projections 22 which are at the same height and in which the distance of the free ends from each other corresponds approximately to the diameter of the inside width of each rod 6.
- the legs 21 pass through correspondingly adjacent openings 14 in the side of each rod 6 opposite the slot 12.
- the arches 20 have the purpose of allowing the straight part of the back 19 to bear against the inside of the rod 6 without the curvatures at the transition between the back 19 and the legs 21 hindering the contact.
- the two slot edges 13 are edged towards the interior of the relevant rod 6, so that the extensions 22 further into the interior of the relevant rod 6 reach.
- the fabric 5 according to FIGS. 5 and 6 is produced as follows:
- the U-shaped connecting element 8 is kept ready, the legs 21 still being fully stretched and having no angled extensions 22.
- the connecting elements 8 provided in this way are inserted through the slot 12 with the legs 21 into the relevant openings 14. After the legs 21 have been pushed through, they are angled to opposite sides on each connecting element 8, so that the oppositely angled extensions 22 are formed. After the relevant rod 6 is fully equipped with the desired number of connecting elements 8 and these are also bent, as shown, the legs 21 are inserted from the side into the slot 12 of the next rod 6 in question. A configuration results, as can be seen in FIG. 5.
- FIG. 7 shows an embodiment in which the connecting elements 8 again run endlessly over the entire length of the fabric 5.
- the rods 6 have the shape explained in connection with FIG. 6 with the difference that only one opening 14 is provided for each connecting element 8.
- the connecting element 8, similar to the exemplary embodiment according to FIG. 2, consists of a continuous spring steel wire.
- the spring steel wire has its original circular shape in the area of the opening 14 and is then flattened, so that a flattened section 23 stands.
- the length of the flattened section 23, seen in the longitudinal direction of the connecting element 8, defines the distance that the adjacent rods 6 have from one another.
- a rod is threaded onto the connecting element in question.
- the connecting element 8 leads first through the slot 12 and then through the opening 14.
- the wire-shaped connecting element 8 which can also be regarded as linear, is flattened in such a way that the longitudinal extent of the flattened section 23 is parallel to the slot 12 lies. This creates an increase in width that creates two shoulders 24 and 25. If the next rod 6 is now threaded onto the connecting element 8, the slot 12, the widened section 23 can easily pass, while the opening 14 with its perforated edges will stand on the two shoulders 24 and 25.
- each rod rests with its inner perforated edges on the shoulders 24 and 25 of each flattened section 23.
- the flattened section 23 is located essentially within each rod 6.
- each rod 6 is individually coupled to the relevant connecting element 8.
- the bottom bar 6 does not have to bear the weight of all those above, as is required, for example, according to the exemplary embodiment according to FIG. 2, and it does not have to, according to the exemplary embodiment according to FIGS. 4 and 6, the top bar in the case of hanging mounting 6 absorb the entire weight.
- FIG. 8 shows an embodiment in which the connecting elements 8 in turn run over the entire length of the fabric 5. Between every two neighboring ones Rods 6, the wire-shaped connecting element 8 is twisted into a loop 26. The diameter of the loop 26 can be smaller than the diameter of the rods 6.
- the distance that the loops 26 have from one another defines the distance of the rods in the case of hanging installation. If the diameter of the loops 26 is chosen to be correspondingly large and adjacent loops 26 almost touch one another, the flat structure 5 cannot be pushed together completely. In any case, a corresponding gap remains between adjacent bars 6.
- FIGS. 9 and 10 show exemplary embodiments in which deformation of a connecting element, which runs over the length of the fabric 6, is also used.
- the connecting element 8 is curved in an undulating manner, the undulating course creating a shoulder 27 on which the rod in question rests with the edge of the associated opening.
- the wavelength with which the connecting element 8 is bent in a wave shape corresponds exactly to the division of the flat structure 5, ie the distance between adjacent shoulders 28 corresponds to the distance between the corresponding parts of adjacent bars 6. 10, the "wavelength" is twice as large.
- Each connecting element 8 is bent in a zigzag shape, with an opening 14 of a rod 6 being located in each reversal point 29 of the zigzag shape. So that the rods 6 cannot fall down, In each case, two adjacent connecting elements 8 are oriented in opposite directions, so that their tips alternately point towards and away from each other, as shown.
- the openings 14 are offset by the stroke of the zigzag pattern.
- the connecting elements 8 are linear, i.e. they consist of a wire.
- the material must be permanently deformable if it is bent over small radii of curvature.
- the connecting element must not be deformed if it is bent around radii of curvature corresponding to the diameter of the winding shaft.
- monofilaments made of plastic can also be replaced as connecting elements.
- Metal is preferred in all other embodiments.
- linear or wire-shaped connecting elements 8 are advantageously used, as is the case in FIGS. 11-15.
- the rods 6 in turn have the cross-sectional shape explained above and consist of a thin-walled roll-formed material. Opposite the slot 12, elongated holes 31 are contained per connecting element, which extend with their longer axis parallel to the longitudinal extension of the rod 6 in question.
- Each connecting element 8 consists of a narrow steel band from which each tongue 32 is notched in the middle.
- the tongue 32 has a rectangular shape and is connected at its upper edge in the use position to the rest of the band. The lower edge is free.
- the individual rods 6 can be threaded in order.
- the tongues 32 deflect to the side in a correspondingly spring-elastic manner, as a result of which attachment is readily possible.
- FIGS. 13 and 14 show an embodiment, similar to the embodiment of FIGS. 11 and 12, only with the difference that the tongue 32 is additionally bent approximately in an L-shape. In this way, a shoulder 33 which is more pronounced than in the exemplary embodiment according to FIGS. 11 and 12 is produced.
- the tongue 32 is released in such a way that, as shown in FIG. 14, it can be seen through the plane defined by the band.
- FIG. 15 finally shows an embodiment in which the notch leads to a bulge 34, the notch being carried out in such a way that there are no free ends in the longitudinal direction of the band.

- the bar profiles shown are not only suitable for windable flat structures 5. It can also be designed as a rigid flat structure. For this it is sufficient if the connecting straps 7 are designed to be stiff.
- the length dimensions specified above can also be increased proportionally, for example in order to provide light protection which is invariably present in front of a light entry opening, for example a window.
- the length dimensions of the rods 6 can be increased accordingly. For example, values of 4 - 5 cm can be provided for edge lengths instead of 4 and 5 mm as stated above. Additional enlargements of the profile are also possible.
- the width of the gap between adjacent rods 6 is between 25% and 100% of the diameter of each rod 6. The smaller the distance, the lower the angle of the sun at which there is direct radiation.
- Rods enlarged in this way can then easily be attached individually in front of the opening in question. It is only important to at least approximate the specified angles. So that enough light can pass through, the distance between the individual rods must be increased or decreased in accordance with the changes in length.
- a flat structure consists of rods that run parallel to one another and are connected to one another by connecting means.
- the connecting means can be designed in such a way that they extend over the entire length of the flat structure, or alternatively NEN should only connect two directly adjacent bars to each other.
- a rod for a sun or light protection device has an essentially pentagonal profile, the profile being provided on the side facing the light with an obliquely upward-pointing groove.
- the channel is delimited by two straight surfaces inclined at an angle of approx. 134 ° to one another and running along the length of the rod.
