Definitions
- the invention is directed to a pull-up window covering of the type specified in the preamble of claim 1.
- a covering initially has the task of serving as a screen. At the same time it is up to him to perform decorative functions; it serves as window decoration and is therefore made from fabric sheets of curtain material, in particular in the form of woven and knitted fabrics.
- the typical feature of this window covering is that straps with loops for guide elements are fastened on one side, hereinafter referred to as the side.
- the pull cords allow the window covering to be pulled up to the desired extent, the fabric web pushing together in an uncontrolled manner between the guide elements, which impairs the good appearance of the window covering.
- the loops run vertically, in the longitudinal direction of the belt, and a single loop serves to hang in a plate-shaped guide element.
- the invention has for its object to develop an inexpensive window covering of the type mentioned in the preamble of claim 1, which can be used equally well for different window heights and which has an attractive, flawless appearance, both in the extended and in the pushed-together state of it Fabric panel distinguished.
- This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning:
- weft bundles can either be worked directly on the fabric web, or they can belong to a prefabricated fold band which is only later attached to the fabric web on the back. is consolidated, for example by sewing on.
- the weft bundles not only have the function r, as will be explained in more detail below, for indirectly or directly guiding the pull cords, but are also means of attack for a connector which is threaded through at least two weft bundles lying at a vertical distance from one another and forming a common one Pull cord belong.
- the area of the fabric in between is gathered together into a horizontal fold at this point, which remains even when the window covering is stretched, that is to say when the pull cord is left completely free, and therefore determines the appearance of the curtain in the basic state.
- the fabric web gathered in different ways has a different appearance.
- This double function of the weft bundles it is possible to design a wide range of different decorations based on a window covering of one type.
- the resulting horizontal folds also give rise to a pre-kinking point on the fabric web, which kinks further at this preferred point when the fabric web is pulled up over the pull cords and therefore also ensures that the window covering looks good when pushed together.
- the invention can basically be carried out in two ways, each of which has its own particular advantages.
- one possibility is to also give the connection a double function, namely not only the producer to be of horizontal folds, but at the same time to serve as a guide element for the associated pull cord. To do this, it is sufficient to provide a guide eye on the connector, through which the pull cord of the finished window covering is then passed. In this way, one should proceed with all the connectors of the window covering, which is why all the points that serve to guide the various pull cords also perform the function of permanently gathering horizontal folds in their area.
- Claim 3 shows an alternative of the invention, which makes it unnecessary to produce additional guide elements for the pull cord and to mount them on the weft bundles, because in this implementation of the invention the weft bundles themselves assume this function.
- This invention can be considerably simplified if, according to claim 4, the pull cord is incorporated in the textile production of the weft bundles itself in the sense of a "filler thread". In this case, there is no need for cumbersome threading of the drawstring because this is introduced from the start when the weft bundles are made by weaving or knitting.
- the invention with its gathering of horizontal folds has the great advantage that the pull cord runs in a straight line in the gathering area of the fabric and thus a gain in length occurs, which can be used for guiding the pull cord in the upper region of the window covering.
- the drawstring When the drawstring is incorporated into the fabric or the associated folding band, the drawstring has the same initial length as the not yet gathered, flat fabric.
- the upper end of the pull cord on a take-up spool to attach the rotation of which then enables the fabric web to be pulled up. In this case, only small excess lengths are required, which are incurred due to the gathering in places according to the invention.
- claim 8 offers an alternative where different pull cords are guided through the various weft bundles in a different pattern, so that one of several different gathers of the fabric web is selected by selecting the suitable pull cord can be used if the connectors are set accordingly.
- Another embodiment of the connector is to form it from a hook, according to claim 13, which is threaded through the various weft bundles.
- the measures of claim 15 result in simple handling and yet safe storage of the detected weft bundles.
- the diametrical arrangement of the contact points according to claim 16 ensures a defined positioning of the associated connector or guide element.
- bracket in the sense of claim 17 gives the great advantage that the bracket then protrudes vertically from the fabric web gathered at this position to the rear and therefore allows the associated pull cord to be passed through particularly well and smoothly, which is easy to handle ⁇ has the pull cord noticeable when pulling up the fabric.
- a crossbar according to claim 18 ensures that a pull cord passed through the loop does not collide with the hook and can get caught on it.
- FIGS. 16 and 17 are sectional views through the fabric web of FIG. 15 equipped with a folded band along the section lines XVI-XVI and XVII-XVII and
- FIG. 18 shows a longitudinal sectional view through a section of the window curtain produced with the fabric web of FIG. 15.
- the window covering 10 shown in FIG. 1 comprises a fabric web 11 which is weighted down in its lower edge region 13 by a rod 12 which is expediently inserted into a fabric web tube.
- a valance 14 can also be provided as a decorative finish.
- the tapes 20 can be designed as knitwear or as a woven fabric.
- the band 20 is fastened to the fabric web 11 by sewing. Alternatively, it would also be possible to apply the tape 20 to the fabric web 11 by means of a weld attachment, which can be quickly and conveniently ironed on by means of an iron or the like. can generate.
- the band 20 comprises a fixed band base 22 with a bundle 24 provided at predetermined intervals 23 of threads 25 floating along the longitudinal direction of the band, which threads 20 are weft threads when the band is being woven, which is why this bundle is hereinafter referred to as "weft bundle 24" shall be.
- the weft threads 25 run close to the two longitudinal edges of the belt base 22. Below the weft threads 25 there is a firmly woven band base. In the suspended state according to FIG. 1, the weft bundles 24 run horizontally, a connector 30 being threaded through in selected weft bundle pairs 24 ′, 24 ′′, as can best be seen from FIGS. 13 and 14.
- the connector 30 used here is shown in large enlargement in FIGS. 2 to 4.
- the connector 30 is formed in one piece from plastic and comprises a U-shaped bracket 31, on which a specially profiled hook piece 32 is molded.
- the two stirrup legs 33 initially run, together with the U-bend, in a common plane 34, best seen in FIG. 3, before they end with angled leg ends 35, which include the actual hook 36 between them, the hook end 37 of which is bent back and even protrudes into the interior of the temple.
- the bracket 31, together with the hook piece 32 defines a self-contained eyelet 38, which in this exemplary embodiment also has a further function to be described in more detail.
- the bracket 31 of the connector 30 initially serves as a handle to be threaded with its free bracket end 39 through the selected weft bundles 24 f , 24 ′′ according to FIGS. 13 and 14. After threading, these finally reach the hook piece 32, which has the special, best seen in FIG. 3, rolled shape, which produces two diametrically opposite contact points 41, 42 in their hook opening profile 40.
- the one contact point 41 is formed by corresponding shapes in the leg ends 35, while the other contact point 42 in the intermediate distance region in the apex of the bent back hook 36 is arranged, which can best be seen from Fig. 4.
- the indicated connecting line 43 between the two contact points 41, 42 is approximately perpendicular to the mentioned arrangement plane 34 of the actual bracket 31.
- This horizontal fold 44 therefore remains when the fabric web 11 is in the stretched position shown in FIGS. 1 and 14, which is caused by the weight of the fabric web and the weighting rod 12 with the valance 14.
- the arrangement plane 34 of the bracket 31 lying at right angles to this connecting line 43 comes in a horizontal position which is best seen in FIG. 14 and which fixes itself.
- the mentioned loop eyelet 38 is free to be used for the implementation of a pull cord 21, the lower cord end 27 of which is attached to the weight bar 12, while its upper cord end 28 is used to pull the fabric web 11 up.
- the curtain has a support rod 29 which is attached in the upper window area and on which to
- deflection members 49 sit for the upper end 28 of the cord 21 and which at the same time serves for the fixed attachment of the upper edge region 48 of the fabric web 11.
- the horizontal folds 44 run continuously over the entire width of the window covering 10, which is, however, not necessary, as is demonstrated with reference to FIGS. 8A to 12B.
- the term "horizontal fold" initially denotes only the current intermediate region 19 of the fabric web 11, which is combined by such a connector 30.
- FIGS. 8 B to 12 B each show the four folding bands 20 which are arranged in the four trains 16, 16 ', 17, 17' indicated there distributed on the back of the fabric.
- arcs 46 illustrate those weft bundles 24 which, as a bundle pair 24 ', 24' 'illustrated in FIG. 11, are each gripped by a connector 30 and brought together to produce a permanent fold 44.
- FIGS. 8 B to 12 B this can be done in very different ways, which accordingly results in a completely different appearance of the curtain 10 on the face side according to FIGS. 8 A to 12 A.
- the looping in of the connectors 30 and the associated appearance of the hanging hanging in the idle state can be seen from the figures of the same number in each case.
- the connectors 30 can be set individually and the taste of the curtain can be different.
- FIG. 9 A By displacing the detected bundles 24 ', 24' of FIG. 9 B in the individual cables 16 to 17 ', a funnel-shaped fold course of FIG. 9 A is obtained. Diagonal threading of the individual connectors in accordance with FIG. 10 B results in that Fig. 10 A visible, along the indicated diagonal line 59 of Fig. 10 running folds.
- the threading according to FIG. 11B of connectors in the individual pleated tapes 20 produces the arch shape in the course of the pleats of the finished curtain from FIG. 11A, while the offset of the threading of the connectors shown in FIG. 12B is that of FIG. 12 A visible loop shape in the course of the folds of the fabric.
- the weft bundles 24 produced and used in accordance with the invention do not have to be part of a separately produced band 20, which is then only later connected to the fabric web 11 producing the woven material in the manner described. Rather, it would be possible to incorporate the weft bundles 24 already during the textile production of the fabric web 11; ie, when this web 1 is woven or knitted, such floating bundles of thread 24 are also produced along the later vertical trains 16 to 17 '.
- the further exemplary embodiment of the invention shown in FIGS. 15 to 18 shows a particularly simple and effective measure.
- FIG. 18 shows in a representation corresponding to FIG. 14 the appearance of such a differently designed window covering 10 '.
- a band 20 'with the weft bundles 24 described is used, but, as can be seen from FIG. 15, this is designed in a manner different from the first exemplary embodiment 10.
- the fold band 20 'obtained in its textile production is therefore equipped from the outset with a longitudinally extending pull cord 21'.
- Fig. 16 shows a cross-sectional view through the curtain along the section line XVI-XVI, where it can be seen that in this area the pull cord 21 'in the gap opening 58 shown in Fig. 16 between the weft bundle 24 and the band base 22'.
- the weft bundles 24 undercut here take on the further function of being a direct guide element for the associated pull cord 21 '.
- FIG. 17 which shows a corresponding cross-sectional view through the fabric web 11 'provided with the band 20', the pull cord 21 'runs above the weft bundle 24, which is why these are not effective for guiding in this area.
- the pull cord 21 pulls freely over three successive weft bundles 57 before it again engages in the subsequent weft bundle 24 ′′ to be detected, as shown in FIG. 16.
- a simpler alternative is also to initially allow all of the weft bundles 24 to be gripped under in the sense of FIG. 16, so that the gap openings 58 located there fulfill the function of guide elements for the individual pull cord 21 ', because separating cuts in the respectively occurring one fold-generating intermediate region 19 'can subsequently obtain the free courses of the pull cord at these points. You do not have to fear fraying of the cut weft threads 25 on the base fabric 22 'if you fix the cut ends by gluing or welding.
- the particular advantage in the embodiment of FIGS. 15 to 18 lies in the fact that on the one hand additional guide elements for the pull cord 21 'on the fabric web 11 are unnecessary and on the other hand that the pull cord 19 has to be passed through manually 'through the respective gap openings 58 between the belt fabric 22' and the weft bundle 24 is unnecessary.
- the formation of the fixed horizontal folds 44 'results in an excess length for the pull cord 21' which could then be used in the sense of FIG. 1 to pull up the cord ends 28. But to use 'the designated in Fig. 14 and 15 Ceiein ⁇ direction for the local drawstring 21 also in this case, so it takes just small excess lengths of
- a horizontal support 50 is arranged in the upper web edge region 48, on which a horizontal shaft 52 is rotatably mounted via bearing blocks 51. Sitting on the shaft 52, in alignment with the various cables 16 shown in FIG. 13, take-up spools 53, to each of which the upper end of the cord 28 is fastened. 13, a drive wheel 55 is fastened to the horizontal shaft 52, expediently in a gear housing 54, around which a drive belt 56 or the like. looped around. By pulling the belt 56, the shaft 52 is optionally set in rotation in the sense of the double arrow 69 shown in FIG.
- an alternative connector 60 according to the invention is shown in different views and states of use.
- This consists of a flexible strip 61 with thickened end pieces 62, 63, between which a slightly flexible bridge 64 is arranged.
- At least one of the end pieces 63 is provided with a guide ⁇ se 68, which is used to guide the later pull cord 21 as already described.
- the two end pieces 62, 63 are provided with mutually complementary closure halves 65, 66, one of which, in the present exemplary embodiment, is formed from a coupling pin 65 and the other from a receiving opening 66.
- the two halves 65, 66 of the coupling can be joined together during elastic coupling and, as is illustrated in FIG. 7, finally form an annular body 67 by bending the deformable bridge 64, which protrudes from the longer-shaped end piece 63 with the guide eye 68 becomes.
- annular bodies 67 could also be used in a different form.
- a simplified connector 60 according to FIGS. 5 to 7 which does not have an end piece 63 projecting beyond the ring body 67 with a guide eye 68. It is then sufficient for the ring shape itself, which could either be solid in the form of a hook 36 which is guided back into itself, according to the connector 30, or which is subsequently formed into an annular body 67 according to FIG.
- the hook 36 runs vertically in use, that is to say in the longitudinal direction of the band, but, as has been described, the eyelet 38 produced by the bracket 31 is horizontal.
- the ring body 67 lies in a vertical plane of the curtain 10, perpendicular to the horizontally extending weft bundles 24 ', 24''which it covers.
