The invention has for its object to further develop a generic shading device nutzsvorteilhaft.

The object is achieved by the invention specified in the claims.

The invention relates to a shading device with at least two mutually parallel rails, which are fastened to a substructure or under a horizontally or inclined to the horizontal substructure, with a sun protection function performing curtain, which is fastened by means of fasteners displaceable on the rails, wherein the fasteners are attached to extending transversely to the extension direction of the rails rods. The rods can be fastened directly by means of the fastening elements slidably received in the rods. But it is also envisaged that the rods are connected via hook elements with the fastening elements. The rods can be stuck in tunnels of the blind. But the rods can also be connected via an adhesive tape connection with the top of the curtain, for example. Can the hanging-facing side of the rod form an adhesive strip in the form of a hook tape. The top of the curtain can wear a trained as a loop tape adhesive tape. When pressing the two adhesive tapes against each other, the elastically bendable hooks of the hook strip engage in the loops protruding from the curtain the loop band. The curtain can consist of a plastic material. However, the curtain preferably consists of a textile web which is a woven fabric. By means of the fastening elements of the curtain is attached to the rails. He can be moved from an open position to a closed position. This is preferably done with a drawstring. The sticking in the tunnels or velcro connected to the top of the hanging rods are in the open position closely adjacent to each other, so that the extending between the bars portions of the curtain down-hanging folds or loops form. An adhesive tape, for example the hook tape, can be glued to the underside of the rod designed as a flat profile rod. The other adhesive tape, for example the loop tape, can be sewn to the top of the hanging. The edges of the adhered to the underside of the flat bar adhesive tape may be covered by an edge web. For this purpose, a U-profile section is first produced in the manufacture of the flat bar, on the bottom of the adhesive tape is adhered. Subsequently, the U-legs are bent into the U-space, so that they overlap the edge of the adhesive tape. In the variant of the invention, in which the rod is connected via a Velcro connection with the curtain, hook elements can be slidably mounted in a C-profile groove of the flat bar. For this purpose, the hook elements form a flat, in particular a rectangular plan having foot, which engages in the C-profile. From the foot protrudes a hook, which can be hooked into the fastener. The hook has a hook leg which projects into an opening of the fastener. The hook elements can be made of plastic. The flat bar may be formed by an extruded aluminum profile. It may have a lateral projection, which rests in the opened state of the shading device on an adjacent rod, so that the parallel juxtaposed rods have a slight distance from each other. A variant for attaching the rods to the curtain form the above-mentioned tunnel. The tunnels can be connected to the Be formed edges of folded portions of the curtain, whose ends are in turn connected to the curtain, for example. Sewn. In each of these tunnels are end rods. One or more further tunnels are provided which extend parallel to the peripheral tunnels and which may be formed by folding the fabric forming sheets or by sewn-on strips. In a further development of the invention, it is provided that at least one end of the rod is inserted in a pocket arranged in an imaginary extension of the tunnel at the edge of the curtain. The bag has a bottom edge. Preferably, each of the two opposite ends of the tunnel is associated with a small distance a pocket. The two pockets form a closed bottom and an opening facing the tunnel. In the pockets, the ends of the rods can be in, so that they can not fall out of the tunnels. The introduction of the rods in the pockets requires a certain stretching of the web. Between the edges of the pocket and its associated opening of the tunnel a fastener is arranged in each case. The tunnel may also have recesses in which, in turn, fasteners are arranged. These recesses are arranged between the two outer tunnel edges, so that both edge-side and middle rails can be used. The fasteners preferably have the shape of conventional curtain gliders. As a result, standardized curtain rails can be used to attach the shading device to the substructure. They are preferably rails with a C-shaped cross-section. Two support shoulders of the rail flank a groove through which the shank of a curtain slider can protrude, which has at its free ends a head which is displaceable on the support flanks. This slider forms the fastener for fixing the rod. Preferably, the fastening element has two mutually parallel legs, which are connected to one another with a web. In side view, the fastener then a U-shape, wherein at the ends of the two U-legs on the one hand the U-web and on the other hand the head is arranged. The rod can be arranged between the two U-legs and be carried by the U-web. The rod may have a non-circular or rounded, deviating from the circular shape, in particular elliptical or oval cross-section. It can rest so close to the U-legs or rest on the U-web, that it rests unrotatably in the U-opening of the fastener. The above-mentioned pull cord is firmly connected to the lowermost slider, in particular a middle rail. For this purpose, the slider can form a cable guide opening into which the pull rope can be inserted. This is preferably done by a head-side incision. Sliders further above arranged rods may also have such a cable guide channel. Through this cable guide channel then the pull cord is slidably guided. For firm connection of a slider to the drawstring, the drawstring may have a knot located between the two legs. In a variant of the invention, a Zugseilklemmeinrichtung is provided. For this purpose, the slider has a connecting web. The connecting web connects the two legs of the slider in the region of their free ends with each other. The connecting web is slightly offset from the cable guide openings, so that the unclamped guide cable can run above the connecting web. The connecting web is thus located between the guide openings and the U-web of the slider, but in the immediate vicinity of the cable guide openings. At its two adjacent to each of the leg ends of the connecting web has slot-shaped incisions into which the guide cable can be inserted so that it rests on the side facing the U-web side of there flat connecting web. It is placed through the slot in a Z-shape. On the side facing the U-web side projections may be arranged, behind which the guide cable is to hold it in the slots. With the drawstring, the bottom bar can be pulled upwards become. It then forms the above-mentioned fabric fold. The lowermost rod increases in its upward movement or - if it is a horizontal arrangement - the next to her lying rods in the course of their displacement from the closed position to the open position. In a variant of the invention it is provided that at the end of the rail, a deflection element, for example. In the form of a Umlenkblocks with a deflection cylinder is to deflect the traction cable substantially 180 °. For example, the pull cable can be placed around a deflection cylinder for this purpose. The returning section of the pull rope passes through a cable guide channel of the rail. The cable guide channel may be a tubular cavity of the rail. But it is also possible that the cable guide channel has a substantially U-shaped cross-sectional profile. The cable guide channel preferably has a wall with which it is separated from the guide opening into which the heads of the sliders engage, so that the return section of the pull cable is spatially separated from the running section of the pull cable by a wall. The fasteners and the returning portion of the pull rope are thus guided in separate cross-sectional areas of the rail. The returning portion of the pull rope is thus preferably not visible from the outside. The running portion of the pull cable is preferably guided or attached to the heads of the fasteners. The leading portion of the traction cable can thus also be performed partially within the rail. At least the trailing portion of the traction cable but only slightly spaced from the rail. At the opposite end of the deflecting the rail can also be arranged a Umlenkblock. This can have pulleys for both the incoming and the returning cable section, so that the curtain is displaceable both in the direction of the open position and in the direction of the closed position by operating the pull cable.

The examples of sun protection devices illustrated in the drawings can each be attached to a horizontal or an inclined, but also in a vertically arranged substructure. In the embodiments, the substructure of three parallel to each other steeply inclined to the horizontal rafters 3 is formed. The rafters 3 are parallel to each other. On the undersides of the rafters are 3 each with the help of fasteners 24 rails 1, 2 attached. The rails are commercially available curtain rails 1, 2 with a substantially round outer profile and a C-shaped guide opening 22. The cavity of the rail 1, 2 is bisected by a central web, so that an outwardly closed, but open to the end faces of the rail 1, 2 towards open chamber 15, which forms a cable guide channel 15. The guide groove, which is bounded by the groove flanks 23, opposite chamber 15 is bisected by another web. This dichotomy is optional. The fasteners 24 are screwed to the rafters 3 and form C-shaped receiving spaces forming clamps, in which the rail 2 can be inserted or clipped.

In the illustrated embodiment extends only through the middle rail 2, a guide cable 16. On the two outer rails 1 no cable pull device is provided.

In the rails 1, 2, which are the same shape, sliders 5, 6 can slide. The sliders 5, 6 have a U-shape. They have mutually parallel legs 10, which are connected to a U-web 12 with each other. In the drawings, in particular the Fig. 11 , is the middle slider with the reference numeral 6 and the two outer slider are marked with the reference numeral 5.

At the free ends of the legs 10 are sliding heads 11, which have a diameter which is sufficiently large, so that diametrically opposite portion of the head 11 on guide flanks 23 of the wall of the guide opening 22 can be supported. The diameter of the leg 10 is smaller, at least in the region immediately adjacent to the head 11, so that it can run between the guide flanks 23, that is to say through the guide groove of the guide opening 22.

The two heads 11 have mutually aligned cuts 14, which extend in the bottom of the incisions to a cable guide opening 13 through which a pull cable 16 can be performed. This cable guide openings 13 also serve to fix the pull rope. For this purpose, it is only necessary to make a node in the pull rope and to arrange the node between the two legs 10. Only the slider 6 needs such an incision. The slider 5, which is in a peripheral rail through which no pull rope is guided, need not have such a cut 14 or a cable guide opening 13.

At first, in the FIGS. 1 to 14 illustrated embodiment, each of the plurality of mutually parallel rods 7, which extend transversely to the extension direction of the rails 1, 2, in a tunnel 8 of the curtain 4. The tunnel of the edge-side bars 7 can be generated by folding and fastening, in particular sewing the panels become. The arranged between the edges tunnel can be formed by a wrinkling or by using an additional fabric web. In the center of the tunnel 8 there is an opening between two tunnel edges 8 ', 8 ". In this opening there is a middle fastening element 6. The elliptical rod 7 is located in the U-space, ie on the web 12 and between the two Thighs 10.

In front of the outer edges 8 'of the tunnel 8 8 pockets 9 are arranged at both ends of the tunnel. These pockets 9 are closed at the edge 4 'of the curtain. They have an edge 9 ', which may be slightly spaced from the edge 8' of the tunnel. Between the edge 9 'of the pocket 9 and the edge 8' of the tunnel 8, a respective fastening element configured as a slider 5 is connected to the rod 7 at the two ends of the rod 7. Again, the rod is in particular non-rotatable and in abutment against the legs 10 and the web 12 in the U-recess.

The ends 7 'of the rod stuck in the pockets 9, so that they can not fall out of the tunnel 8 side. However, a removal may be possible if the material of the blind is stretchable such that one end 7 'of the rod 7 can be brought past the edge 9'. The sliders 5, 6 can be arranged displaceably on the rods. The mobility facilitates in particular the assignment of the slider 5, 6 to the rod 7. Namely, the rod can not be inserted through the gap between the two heads 11, if this, as in the FIG. 14 shown, extend into the U-space. In the in the FIG. 13 illustrated embodiment, the rod 7 but can be inserted between the two heads 11 in the U-space.

The pull cord 16 fixedly connected to the lowermost slider 6 of the middle rail 2 is guided by the cable guide openings 13 of the higher-lying slider 6 and is deflected by a guide block 17 located in front of the upper end face of the middle rail 2. For this purpose, the screwed to the substructure 3 guide block 17 has a deflection cylinder 18 to which the pull cable 16 is deflected. It is then passed through the cable guide channel 15 through the rail 2.

Before the other end of the rail 2 there is another deflection block 19 with two pulleys 20. About a guide roller 20 runs in the rope guide channel 15 guided rope. About the other roller 20 which is attached to the lower slider 5 other end of the guide cable 16, with the curtain can be pulled from the open position back into the closed position.

It is considered to be particularly advantageous that the attachment of the rods 7 to the rails 2 by means of fasteners 5, 6 can be made, the size of their trade and commercial Gardinengleitern same. It can therefore be used as rails 1, 2 commercial curtain rails with C-shaped cross-section. By the rods 7 einliegen in tunnels or pockets, they are firmly connected to the curtain 4 in a simple manner. By using U-shaped slides 5, 6, a simple fixation of the slider to the rods 7 on the one hand and to the rails 1, 2 on the other hand ensured. The upwardly open U-opening is closed at the moment in which the sliders 5, 6 are threaded into the rails. The rods 7 are then in an encircling opening, wherein the opening of the legs 10, the web 12 and the underside of the rail 2 is framed.

In the in the FIGS. 16 to 22 illustrated second embodiment, the curtain also depends on commercial curtain rails with C-shaped cross-section. The guided in the guide opening 22 of the rails 1, 2 slides 5, 6, have a U-shaped configuration. The slider 6 forms two mutually parallel legs 10, at the free ends are sliding heads 11. The U-web 12 is located at the ends pointing away from the sliding heads 11. The two sliding heads 11 have cable guide openings 13 which are aligned with one another. Towards the U-web 12, offset immediately adjacent to the cable guide openings 13, there is a flat connecting web 35 which connects the two ends of the legs 10 with each other. Immediately adjacent to the respective leg 10, a lateral recess 36 is provided at both ends of the connecting web 35. In this slot 36, a guide cable 16 can be clamped, which lies in the cable guide opening 13. It is thus deflected approximately at a 90 ° angle. The traction cable then runs on the side facing the U-web 12 flat side of the connecting web 35, where it is again deflected by 90 °. In order to fix the traction cable 16 on the flat side of the connecting web 35, projects from there at least one projection 37 in the direction of the U-web 12. Behind the at least one projection 37 is the pull cable 16, so that it does not slide out of the slots 36 can. In the embodiment, two projections 37 are provided, which adjoin directly to a respective slot 36.

In the in the FIGS. 16 to 22 illustrated second embodiment, the rods 28 are held by means of hook members 25 on the sliders 6. The hook elements 25 are made of plastic, have a foot 27 in the form of a substantially rectangular base plate and a protruding hook 26. The hook 26 has a directed towards the foot 27 hook end 26 '. This hook end 26 'can be hooked over the U-web 12, so that the hook leg 26 ", which runs parallel to the foot 27, rests on the U-web 12 of the slider 6.

In the second embodiment, the rod 28 is formed by a flat profile. It is an extruded aluminum profile with two facing away from each other flat sides, each forming U- or C-shaped grooves. In a C-shaped profile groove 29 of the foot 27 of the hook member 25 is slidably mounted. There are a plurality of hook elements 25 arranged in the profile groove 29. The number of hook elements 25 corresponds to the number of rails 1, 2.

The C-profile 29 opposite flat side of the flat bar 28 forms an adhesive surface. For this purpose, an adhesive tape 31 is connected to an adhesive strip 32 with the flat side. In the exemplary embodiment, the two edges of the adhesive strip 31 are overlapped by edge webs 33 of the profile of the flat bar 28. This can take place in that the adhesive strip 32 provided with the adhesive layer 32 is first adhered to the bottom of a U-profile groove. Subsequently, the profile edge webs 33 are formed to the inside. The adhesive strip assigned to the flat bar 28 may be a hook strip 30, which has an adhesive surface which is tightly provided with elastically deflectable hooks.

The adhesive strip 30 can be brought into a Velcro connection with an adhesive strip 31 which is formed as a loop tape. The adhesive strip 31 may be connected to the top of the curtain 4 by sewing.

The FIGS. 19 and 20 show two different variants of a hook element 25.
