Definitions

  • the invention is directed to a pull-up window curtain of the type specified in the preamble of claim 1.
  • a curtain serves as a privacy screen, but also has decorative functions. It serves as window decoration and consists of fabric sheets of curtain material in the form of woven or knitted fabrics.
  • guide elements are held by loops, which lie in parallel vertical rows and serve to guide a pull cord.
  • the pull cords allow the window covering to be pulled up to the desired extent. There is a risk that the fabric will slide together in an uncontrolled manner between the guide elements and thereby impair the good appearance of the window covering. Furthermore, it is necessary to cut the window covering to match the respective height of the window, which is cumbersome.
  • the guide elements are designed as flat plates with a transverse slot for inserting the loops, where the slot runs horizontally to the installed window covering. Therefore the loops on the fabric must be oriented vertically, in the direction of hanging the fabric. Otherwise, the guide elements would be oriented transversely to the direction of the pull cord, which would lead to pinching when pulling the cord.
  • a high level of effort is required to manufacture these loops by textile technology. Assuming woven ribbons with such loops, they have to be produced by warp thread elements in a laborious, costly weaving process.
  • eyelets oriented in the hanging direction are attached to the fabric web and run along vertical seams and are arranged at a defined distance from one another.
  • the eyelets consist of small plastic rings, the ring plane of which runs in a vertical plane.
  • the eyelets on the fabric can only be attached with considerable effort and expense.
  • large plastic rings provided with closing elements at the ends, which are threaded through at least two eyelets on the fabric web and then closed with their closure elements to form an endless ring.
  • the plane of the rings runs in a parallel plane to the suspended fabric. Horizontal loops on the fabric web are neither provided nor suitable for passing these plastic rings through.
  • the plastic rings be used as guide elements for any pull cords because the ring openings are not oriented in the vertical direction of the finished window covering. This would result in a self-clamping of the pull cord in the plastic ring, which would basically preclude pulling the cord.
  • 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 is characterized by an attractive, flawless appearance both in the drained and in the raised state of the fabric. This is achieved according to the invention by the measures set out in the part of claim 1, which have the following special meaning:
  • the loops consist of a bundle of floating weft threads
  • the loops according to the invention can be manufactured quickly and inexpensively. These bundles can either be worked on directly on the fabric web or they can belong to a prefabricated band which is only later attached to the fabric web on the back, e.g. by sewing on. If necessary, the loops could also be designed in a different way.
  • the weft bundles are used to thread a connector that has a double function. First, it creates a horizontal fold in the area between two weft bundles, which remains even when the pull cord is completely free and the window covering is in a stretched state.
  • connectors there are various options for producing the connectors, each of which has its own particular advantages. Basically, it is sufficient to start from an annular body according to claim 2. To simplify the threading, it is also possible for abar to be designed flexibly and, according to claim 3, to be subsequently converted into the ring shape. Closure halves at the ends of such a flexible strip are suitable for this, as claimed in claim 4.
  • Another embodiment of the connector is to form it from a hook, according to claim 5, which is threaded through the various weft bundles.
  • a hook according to claim 5
  • the eyelet mentioned there at the same time can take over the function already mentioned at the beginning of forming the guide eyelet for the subsequent pull cord.
  • a simple handling and yet safe storage of the detected weft bundles results from the measures of claim 7.
  • the diametrical arrangement of the contact points according to claim 8 ensures a defined positioning of the associated connector or guide element.
  • bracket in the sense of claim 9 gives the great advantage that the bracket then projects vertically from the fabric web gathered at this point to the rear and therefore allows the associated pull cord to be passed through particularly well and smoothly, which results in easy handling the pull cord is noticeable when pulling up the fabric.
  • a crossbar according to claim 10 ensures that a pull cord passed through the loop does not collide with the hook and can get caught on it.
  • 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 expediently inserted into a fabric web tube. Following this, a valance 14 can be provided as a decorative finish. On the rear side 15 of the fabric web 11, which is visible in FIG. 1, a plurality of vertical trains 16 of bands 20 of the same type are arranged, which indirectly serve to guide a pull cord 21 and whose appearance and function can best be seen from FIGS. 13 and 14.
  • the tapes 20 can be designed as knitwear or as a woven fabric.
  • the band 20 is attached 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 produced quickly and easily by ironing on using an iron or the like.
  • 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 are weft threads when the band is being woven, which is why this bundle will be referred to as "weft bundle 24" in the following.
  • 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 belt 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 bow legs 33 initially run, together with the U-bend, in a common plane 34, best seen in FIG. 3, before they run out 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 defines, together with the hook piece 32, 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 ', 24 "according to FIGS. 13 and 14. After the threading, these finally reach the hook piece 32, which is the special one 3, which is best seen in Fig. 3 and which produces two diametrically opposite contact points 41, 42 in its hook-opening profile 40.
  • One contact point 41 is formed by corresponding shaping in the leg ends 35, while the other contact point 42 in the intermediate one Distance region is arranged in the apex of the bent back hook 36, which can best be seen from Fig. 4. According to Fig.
  • the indicated connecting line 43 between the two contact points 41, 42 is approximately perpendicular to the mentioned arrangement level 34 of the actual bracket 31 This has the consequence that the one weft bundle 24 'at the contact point 42 and the another 24 "comes to rest in the hook piece 32 at the opposite contact point 41 when the use of the window covering shown in FIGS. 13 and 14 is present. Due to the force of gravity, the connecting line 43 lies in a vertical plane, parallel to the web pieces 18 ', 18 "beginning at the two weft bundles 24' and 24". The Intermediate area 19 of the fabric web 11 is gathered together to form a horizontal fold 44, the fold foot 45 of which, as can also be seen from FIG.
  • the curtain has a support rod 29 which is attached in the upper window area and on which, in the case of FIG. 1, deflection members 49 for the upper end 28 of the cord 21 are seated and which at the same time are used for the fixed attachment of the upper edge area 48 the fabric 11 serves.
  • the horizontal folds 44 run continuously over the entire width of the window covering 10, but this is 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. 8B to 12B each show the four fold bands 20, which are arranged distributed in the four trains 16, 16 ', 17, 17' indicated there on the back of the fabric web.
  • arcs 46 illustrate those weft bundles 24 which are each gripped by a connector 30 as a bundle pair 24 ′, 24 ′′ illustrated in FIG. 11 and which are brought together to produce a permanent fold 44.
  • FIG 8B to 12B illustrate in a very different way, which accordingly results in a completely different appearance of the curtain 10 on the face side according to FIGS. 8A to 12A.
  • the looping in of the connectors 30 and the associated appearance of the curtain hanging in the idle state result from the figures of the same number in each case.
  • the connectors 30 can be set individually and the taste of the curtains can be different.
  • FIG. 10B By displacing the detected bundles 24 ', 24' of FIG. 9B in the individual trains 16 to 17 ', a funnel-shaped fold course of FIG. 9A is obtained. Diagonal threading of the individual connectors in accordance with FIG. 10B results in the folds that can be seen in FIG. 10A and run along the indicated diagonal line 59 in FIG. 10.
  • the threading according to FIG. 11B of connectors in the individual fold bands 20 produces the arch shape in the fold course of the finished curtain from FIG. 11A, while the offset of the threading of the connectors shown in FIG. 12B produces the loop shape in the fold course of the fabric web shown in FIG. 12A causes.
  • the weft bundles 24 produced and used according to the invention do not have to be part of a separately produced band 20 which is then first connected to the fabric web 11 producing the curtain in the manner described. Rather, it would be possible to incorporate the weft bundles 24 even during the textile manufacture of the fabric web 11 itself; i.e. When this web 11 is woven or knitted, such floating bundles of thread 24 are also produced in regions along the later vertical trains 16 to 17 '.
  • 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 transmission housing 54, around which a drive belt 56 or the like is wound.
  • the shaft 52 is optionally set in rotation in the sense of the double arrow 69 shown in FIG. 14, as a result of which the pull cord 21 is more or less wound onto the spool 53 and therefore the treatment 10 from its extended position largely covering the window front of Fig.
  • FIG. 5 to 7 is a alternative connector 60 according to the invention shown in different views and use states.
  • 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 eyelet 68, which is useful for the passage of the later pull cord 21 already described.
  • the two end pieces 62, 63 are provided with mutually complementary locking tabs 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 closure halves 65, 66 can be joined into one another during coupling under elastic deformation and, as is illustrated in FIG. 7, finally form an annular body 67 by bending the deformable bridge 64, which is protruded by the longer-shaped end piece 63 with the guide eye 68.
  • 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 then lies horizontally.
  • the annular body 67 lies in a vertical plane of the curtain 10, perpendicular to the horizontally extending weft bundles 24 ', 24 "which it has grasped.
