Description

The invention relates to a sheet-like, foldable curtain material, in particular a textile material, for a Open from a substantially straight, level Sun closed position transverse to the opening direction Protection and / or privacy curtain, especially for a winter garden or the like, in which transverse to the opening direction each with a predetermined mutual distance continuous recordings in the manner of loops or the like  are trained, in each of which a (leadership and ver stiffening) lath or the like is to be arranged and held.

The invention further relates to the use of a Tablecloth goods known, essentially single-layer, web shaped, foldable textile material, which in its Longitudinal and / or transverse direction with two-layer woven, through going strip-shaped sections is formed as Curtain material for a sun protection curtain.

Finally, the invention relates to a method for confectionery tion of the curtain fabric for such a sun protective curtain made from a sheet-shaped, thermoplastic (Starting) textile material, especially at least one sections of two-layer sheet-like curtain material.

As already indicated above, here are in Sun protection curtains in question, especially for so-called. Winter gardens in private living areas determined and suitable, which has been increasing in recent years for new buildings ten of residential buildings are immediately conceived and at existing residential buildings have been retrofitted.

The relevant industry has become aware of this needs and now offers one Variety of different conservatory building systems that from full glazing with simple wooden frames over a Plastic design up to a largely fully iso training from foamed aluminum profiles or the like.

Although the tendency towards equipment is particularly private Residential houses with conservatories have been clear for years has become recognizable even today that of the corresponding providers the problem of an effective Ver  shading of winter gardens (at least initially) only next to at mentioned or even largely ignored. This is based in particular on the fact that a satisfactory and effective sun protection of a winter garden that belongs to the sen use, to protect the regularly in a winter garden set up plants against excessive temperatures etc. is indispensable, is significant in terms of cost. A optimal shading of a winter garden not seldom to about the same or even higher Costs than the winter garden itself, so that potential in interested in their original plan to build a winter gardens often drop when applicable over the total cost (including the possibility of shading of the winter garden).

Because the sun's rays are regularly ver glass conservatories often not only to a highly unsan pleasant glare from people in the winter garden leads, but above all - even with relatively low outside temperatures - too high inside temperatures ture can lead both for people and for Plants are often significantly too high should one (in the Generally internal) sun protection basically a ver have relatively strongly reflective surface and this as close as possible to the glazing in question be appropriate in the way up to 80% and more reflect the incident solar energy and thus ver to be able to prevent that the one behind the sun protection Room warms up too much. There is a distance of one such sun protection from about 3 to 10 cm to the concern the glazing proved to be very effective and therefore useful sen.

Between glazing on the one hand and assigned sun protection on the other hand, heat build-up should be avoided and  accordingly for effective air circulation with ventilation in upper area.

For the curtain material of a sun protection process are e.g. B. under the trademarks "Alustar" and "Thermostar" Tissue constructions have been made known for the purpose high reflection of the incident sun rays on one side are coated with aluminum and yet still one have sufficient transparency, which largely allows an undisturbed view outside.

There is the curtain fabric of such a sun protective curtain (largely independent of the chosen concrete fabric construction) regularly from a web-shaped gene, foldable (especially textile) material in the transverse to the opening direction with a predetermined counter side distance continuous recordings are formed in each with a (guide and / or stiffening) crossbar or the like. is arranged and held. Such also as Curtain marked with slats or the like i.a. on its side edges (especially with tels of the inserted slats) in rails, which For example, be attached laterally to a window frame and preferably run from top to bottom or vice versa.

The above and below (based on the term "Se gellatten ") elements briefly labeled" laths or the like ", the in the previously mentioned recordings of the front slope curtains of a sun protection curtain are brought in, generally exist made of light metal telescopic tubes (e.g. from Aluminum or an aluminum alloy), one (i.a. spring-loaded) telescopic version (already) is therefore appropriate, and the necessary management of the Curtain between the side tension and guide rails even if the one side edge of the  Blind when opening or closing relative to the other leading or trailing, the "slats" then on this So no longer place at right angles (= across) to the opening or closing direction, but under one (i.a. relatively small) acute angle. This can be seen at Consequence that be in the longitudinal direction of a curtain measured distance between the two clamping and guide rails (the distance between the two ends of a staff) compared to the intended transverse position for opening or Closing direction enlarged. Would you go for the slats no telescopic version would have been seen Lich consequence that at least one slat end on the would move out associated guide rail and in the Then rule by hand back into the relevant guide rail ne would have to be threaded, which of course is highly is undesirable.

The recordings of known curtains (= made-up pre hangings) for sun protection curtains have so far been used forms that on one side of the curtain material (from opti or aesthetic reasons regularly at the view side facing away from the glazing) Loops in or sewn into the material the. In the case of the known curtains, each becomes Production of such a "loop" as it were outward fold formed and this on their the End facing the blind level sewn with a seam. in the finished condition of a sun protection curtain then surrounds one each formed from such a fold by sewing So-called "loop" which is generally essentially a cylinder shaped telescopic slats (relatively tight) essentially circular.

Quite apart from the fact that the manufacture of such "Loops" is very complex because they are only of high quality  graceful, skillful seamstresses is such sun protection curtains (in the closed Condition) when viewed from outside under aesthetic not entirely satisfactory from a because over the entire length of the curtain (each with counter existing distance) existing bead-like structures (existing made of telescopic slat on the one hand and the sly surrounding it fe on the other hand) are very noticeable.

The present invention is based on the object (especially textile) curtain material for a sun to create protective curtain, which with considerably less Effort with the greatest precision and practically without irregularities moderation is producible, and moreover the appearance of the curtain in closed or partially closed condition is to be improved.

A solution to this problem is ge according to the invention indicates that for the creation of such a curtain- or curtain material two superimposed, single-layer Layers made of foldable, sheet-like material at right angles to the opening direction of the curtain to be formed imagined first lines and parallel ge always thought of second lines with opposite term spaced connection points with each other are or are connected, the area between a first line and a neighboring one assigned to it second line a receptacle for a slat or the like. forms, and wherein the curtain material in the opening direction of the curtain to be formed continuously - and preferably each with the same mutual distance with pairs first and second lines (or one line each corresponding connection points) is provided.  

A preferred embodiment of such a curtain draws is characterized in that in each case on a first or second Line first connection points lie, their (first) distance to a first neighboring connection point essentially is equal to the distance to the assigned second line, and each in the opening direction of the curtain to be formed aligned with a first connection point of the second line lie, and that each to a first connection point adjacent first adjacent connection point of a first Line in turn to a first connection point of the second line adjacent first adjacent connection point of this assigned second line in the opening direction of the curtain to be formed is aligned.

The (second) distance between one can be preferred first connection point and that on the same line assigned second adjacent connection point (elev Lich) larger than the (first) distance of a first ver point of connection to his lying on the same line first neighboring connection point, and further the (second) distance between a first connection point and the second adjacent ver be the same size on both lines, so that so that the corresponding curtain material in both its Shot direction as well as in its direction of opening direction of the curtain, because with each of these both arrangements in each case across the opening direction available recordings are available.

If the two layers of material are textiles Material, as is preferably the case, can both material layers of the curtain material are preferred in each case essentially at the connection points with be interwoven so that in such a configuration then not even a punctiform stitching,  Gluing, welding or any other connection in an additional operation is required.

Although it can be seen - even with textile raw material - in principle it is quite possible to take the pictures ("Smart fen ") on one side of the curtain material further preferably provided that the two layers spat gel symmetrical to a roof running between them th plane of symmetry are arranged. This leads clearly not only to the fact that appropriate curtain material significantly is better (e.g. in reeled bales), and that it is not too sharp wrinkles in the loading realm of recording, but beyond that in finished condition especially that the slats contour on both sides of the curtain when open only half pronounced. Thus, the known Be slope materials perceived as aesthetically undesirable The formation of bulges in the area of the slats is avoided and prevented an optically very pleasing wave formation (with half maxi Painterly extent compared to a corresponding one Bulge) replaced, the pleasing appearance above is also significantly improved that Erhe Exercise the curtain material in the area of a recording or a latte does not take place suddenly, but rather - in relation to the main plane between the shots lying curtain areas - steadily increasing, so that form aesthetically highly satisfactory light waves that even - in contrast to the previously known beads - to an interesting, aesthetically satisfying structure the curtain.

Another inventive solution to the above object consists of the connection of an essentially single-layer, web-shaped, foldable textile material, which in its Longitudinal and / or transverse direction with two-layer woven, through  going strip-shaped sections is formed as Curtain material for such a sun protective curtain, with each transverse to the opening direction with a predetermined mutual distance loop-shaped recordings are formed, in each because a generally telescopic slat or the like order and keep, the integral with the inlet common areas preferably connected by interweaving two-layer strip-shaped sections across the opening direction are or will be and the recordings for form the slats of the sun protection curtain. It is for the responsible expert surely to be superfluous notice that such two-layer areas are self-evident also available in both the longitudinal and transverse directions can be such a textile material both in weft as well as in the reverse direction in the opening direction of the curtain to be able to order.

Such an at least similar textile material is indeed for years as tablecloth material (to create according to structured tablecloths), but is the experts, despite the fact that Be need, the previously known curtain materials decide dend to improve, not on the thought of such Use came.

For appropriate tailoring of the curtain. or curtain fabric for such a sun protection curtain the present invention to avoid apparent Schwie rig trainee, section seams in particular the side edges of the curtain for a fiction moderate curtain material continues that the web Curtain material in particular on his regarding the given NEN width (but also in terms of its length) given margins in the specified size under the influence of heat  and pressure is separated from the sheet-like starting material and at the same time is provided with a welding edge, where before the thermal separation in each of the Edge sections of the recording a strip-shaped separator element made of a material that cannot be welded to the curtain material Material is inserted, which is at least up to the relevant edge extends, with the release agent preferred so introduced into the edge sections of the recordings be that before the (thermal) separation process protrude over the edge in question, so that they follow thermal separation, which also involves a welded Seam is created until immediately on the relevant edge extend and in the simplest way from the subject can be pulled out before entering this then inserted a (usually telescopic) staff becomes.

Fig. 1 of the drawing shows two first embodiments of a sheet-like, foldable curtain material according to the invention 1 made of woven textile for a when opening from a substantially elongated flat or curved closing position transverse to the opening direction 2 foldable sun protection curtain 3 , as in the embodiments in the Fig. 11 to 15 is shown, each for a sun protection curtain 3 , as it is used in particular for conservatories, in which transversely to the opening direction 2 each with a predetermined mutual distance c between the side edges 4 or between side guide rails 5 of the sun protection curtain 3 continuous recordings 6 are formed, which in the professional world are also referred to as "loops", in each of which a (guide and stiffening) crossbar 7 is to be arranged or held, as in particular to 21 are visible in FIGS. 17.

The curtain material 1 according to Fig. 1 consists of two superimposed (s. Fig. 2) single-layer layers 8 and 8 'of a foldable sheet-like textile material. In this case, at points transverse to the opening direction 2 of the sun protection curtain 3 to be formed on (imaginary) first lines 9 and parallel (imaginary) second lines 10 running parallel to each other, there are connection points 11 at which the two layers 8 , 8 '(As it were Punktför mig) connected to each other, the area between a first line 9 and an associated neigh disclosed second line 10 each forms a receptacle 6 for a crossbar 7 , and wherein the curtain material 1 in the opening direction 2 of the curtain to be formed 3 continuously and each with the same mutual distance c with pairs of first and second lines 9 and 10 respectively.

In the exemplary embodiment according to FIG. 1a), which shows the basic concept of such a curtain material 1 for a sun protection curtain 3 , the mutual distance of the connection points 11 is on both the first lines 9 and the second lines 10 (of which in the cut-out drawing according to Fig. 1a) in each case represents only one Darge is random) or different in each case and to a large extent arbitrary, the distances between them be adjacent connecting points 11, must and 10 only are so close to 11 on a line 9, that of the two ge lines 9, 10 and their connection points 11 together a receptacle 6 is formed for a ge as an aluminum telescopic rod 7 is formed.

Since such an irregular distance between adjacent connection points 11 , 11 on a line 9 or 11 is generally not desired from an optical or aesthetic point of view, such an embodiment is generally made in accordance with FIG. 1b), but not only that mutual distance between two adjacent Ver connection points 11 , 11 on each line 9 or 11 is the same size, but also a connection point 11 on a first line 9 to an adjacent connection point 11 on the first line 9 adjacent and assigned second line 10 is aligned in the opening direction 2 .

A preferred embodiment of a curtain material 1 designed in principle according to FIG. 1 is shown (somewhat schematically) in FIGS . 3 and 4. Here, each point on a first line 9 lying first connection points 11.9.1 . a first distance d to a first adjacent connection point 11.9.2 . on, which is equal to the distance d from the assigned second line 10, with a first connection point 11.9.1 in the opening direction 2 of the curtain 3 to be formed. assigned first connection point 11.10.1 . the second line 10 in the opening direction 2 to the relevant first connection point 11.9.1 . flees. In addition, the first connection point 11.10.1 is aligned . adjacent connection point 11.10.2 assigned to the second line. in the opening direction 2 to the connection point 11.9.2 .

In contrast, the second distance d between a first connection point 11.9.1 . or 11.10.1. and the second adjacent connection point assigned to it on the same line is considerably larger than the first distance d.

This highly expedient embodiment has the consequence that the curtain material 1 can be used both as a curtain in the position shown in FIGS. 3 and 4 and also in a position rotated by 90 ° (in the plane of the drawing), since through the connection points 11 , the - As can be seen from Fig. 3 - each lie at the corner points of a square with the side lengths d, not only the recordings 6 lying transversely to the opening direction are formed in FIG. 3, but also, at right angles thereto, recordings 6 'which in If the curtain material 1 were used in a position rotated by 90 °, the receptacles 6 for receiving the slats 7 would form.

In addition, in an embodiment according to FIGS. 3 and 4, the arrangement of the connection points 11 (if these are recognized at all by the eye) result in a uniform, aesthetically highly satisfactory "pattern".

A detection of the connection points 11 can be provoked, as it were, by special conspicuous design. If you do not want this, and the connection points 11 are created by interweaving the two layers 8 and 8 'of the curtain material 1 , this not only results in a highly practical and, moreover, also inexpensive production possibility for the recordings 6 (or for the potential recordings 6 '), but the advantageous aesthetic effect is also reinforced by the fact that the transition areas 1 ' steadily and gently rounded duri fen when the slats 7 are inserted into the recordings 6 , which - in contrast to the known prior art - In particular, this results in the fact that the two layers 8 , 8 'are arranged mirror-symmetrically to an imaginary plane of symmetry 12 running between them, and since the "bead height" on both sides of the curtain with the same cross-section dimensions is evidently only half as large as in the prior art .

A further expedient embodiment of a curtain material 1 according to the invention results from FIGS . 5 to 10, in which the same or equivalent parts, elements etc. are provided with the same reference numerals.

Here, 5 and 6, Figs. First of all, a back clear width and length of the larger section of a newly necessary for a sun-protection curtain 3 highly suitable curtain material 1 which is a formed layers in the embodiment according to FIGS. 5 to 10 square portions 13 is and in the intervening, overall forming a kind of grid double-layered areas, the two-layer strip-shaped sections integrally woven with the single-layer areas 13 are arranged transversely to the opening direction 2 in the state of use and the recordings 6 form for the slats 7 , or formed at right angles to the recordings 6 "channels 6 '" potential recordings men for use of the curtain material 1 in a 90 ° (in the plane of the drawing) rotated use position.

If, for a curtain material 1 shown in FIGS. 5 and 6, a curtain to be made up, and there is the line of intersection determined 14 and 14 '(where the dash-dotted dargestell th cut line 14 the right-hand side edge 4 of for forming the curtain and at right angles thereto extending cut line 14 'To form the lower edge of the curtain), so - if necessary after a previous cut on the section line 14 ', - in the transverse to the later opening direction 2 double-layered sections plate-like or strip-shaped separating means 15 according to FIG. 7 so in the Edge sections of the transverse to the opening direction 2 double-layered areas introduced that they protrude beyond the current side edge 4 'of the curtain material, and the cutting line 14 , which forms the corresponding side edge 4 after finished assembly, then there under the action of heat and pressure from the web-like starting material rial 1 separated so that the Z 8 according to FIG . This creates a welding edge on the section line 14 of each layer, if it is, for example, a thermoplastic starting textile material as in the illustrated embodiment, so that a later attachment of seams or seam sections is not necessary. However, as intended, there is no welding between the two layers in the edge area 4 in the area of the later images to be formed, specifically because of the separating elements 15 , which consist of a material that cannot be welded to the textile material. These can therefore be removed by pulling out after the thermal formation of the cutting edge 14 according to FIG. 9, so that the slats 7 can then be inserted into the receptacles 6 formed in this way (see FIG. 10). At the bottom edge 16 , on the other hand, as is also desired - an overall continuous weld seam is achieved, since there - as stated - during the thermal laying of the cutting line 14 ', no separating elements 15 are inserted.

With the present invention, the so-called curtains of sun protection curtains 3 of any design can be produced in a technically, aesthetically and economically optimal way, be it that it is a flat ceiling system according to FIGS . 11 to 13, a curved unit shown in FIG. 14 or an angle system of FIG. 15 is, wherein it is also any apparent that the sun protection curtain 3 with a manual drive 17 via the exporting approximately examples of FIG. 12 and drive 13, or with a motor on 18 as is provided in the exemplary embodiments according to FIGS. 11, 14, 15 and 17.

Also, the design of the "slats" 7 can be seen by the curtain material according to the invention in no way be limited, since the receptacles 6 and their dimensions according to the respective design or dimen sionation of the slats 7 used can be easily adapted.

Due to the fact that the creation of the connection points 11 and thus the receptacles 6 is practically possible without a separate operation in textile materials, and that, furthermore, according to the invention for thermoplastic textile materials, a highly expedient manufacturing method has been proposed, the curtains according to the invention are for sun protection curtains 3 evidently considerably cheaper to manufacture. In addition, they meet the highest aesthetic requirements for the reasons mentioned above, although a variety of different configurations is still possible.
