Description

Die Erfindung betrifft einen Stoff für Sonnenschutzeinrichtungen, insbesondere für Rollobehänge oder dergleichen sind in vielgestaltigen Ausführungsformen auf dem Markt und dienen dazu, die direkte Sonneneinstrahlung in Innenräumen zu verhindern und die Innenräume ausreichend zu beschatten. Insbesondere sind diese bekannten Stoffe so gewebt, dass sich eine möglichst geringe Direktlichttransmission ergibt, dass also die direkte Sonneneinstrahlung mit der damit verbundenen Blendwirkung zuverlässig unterbunden wird. Alternativ sind auch Stoffe bekannt, die transparente Eigenschaften aufweisen, die jedoch eine direkte Sonneneinstrahlung zulassen, welche zur Blendung von Personen in dem beschatteten Raum führen kann. The invention relates to a fabric for sun protection devices, in particular for roller blinds or the like are in many forms on the market and serve to direct sunlight indoors to prevent and shade the interiors sufficiently. In particular these known fabrics are woven in such a way that they are as small as possible Direct light transmission means that the direct solar radiation with the associated glare is reliably prevented. alternative substances are also known which have transparent properties, but which allow direct sunlight, which can dazzle people can lead in the shaded room.

Dabei ist es nachteilig, dass die bekannten Rollostoffe - zur Unterbindung der direkten Sonneneinstrahlung - sehr dicht gewebt sein müssen, so dass eine Durchsicht durch den Stoff von innen nach außen nicht möglich ist.
Aufgabe der Erfindung ist es daher, einen Stoff für Sonnenschutzeinrichtungen der eingangs genannten Art derart weiterzubilden, dass der Stoff eine geringe direkte Sonnenlicht-Einstrahlung zulässt, jedoch andererseits eine relativ hohe Durchsicht nach unten gewährleistet.It is disadvantageous here that the known roller blind fabrics - to prevent direct sunlight - have to be woven very tightly, so that it is not possible to look through the fabric from the inside out.
It is therefore the object of the invention to develop a fabric for sun protection devices of the type mentioned at the outset in such a way that the fabric allows little direct sunlight, but on the other hand ensures a relatively high level of visibility downwards.

Diese Aufgabe wird bei dem Stoff der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass mindestens einige Fäden erster Art in einer ersten Richtung, beispielsweise Schußfäden oder in Schußrichtung verlaufende Zusatzfäden Rippen oder Lamellen bilden, deren Querschnitt im wesentlichen quer oder senkrecht aus der sonstigen Stoffebene absteht.This object is achieved according to the invention in the case of the substance of the type mentioned at the outset solved in that at least some threads of the first kind in a first Direction, for example weft threads or additional threads running in the weft direction Form ribs or fins, the cross section of which is essentially protrudes transversely or vertically from the other plane of the fabric.

Die Vorteile der Erfindung liegen insbesondere darin, dass einige der vorhandenen Fäden erster Art in einer ersten Richtung so angeordnet sind bzw. einen solchen Fadenquerschnitt besitzen, dass diese ersten Fäden eine vergleichsweise große Querschnittsausdehnung in einer Richtung aufweisen, die senkrecht zu der sonstigen Stoffebene verläuft, wobei die Stoffebene insbesondere durch die Fäden zweiter Art festgelegt ist, welche quer oder senkrecht zu den Fäden erster Art verlaufen. Diese aus der Ebene der zweiten Fäden nach außen abstehende, parallel zueinander verlaufende Rippen oder Stege wirken wie die in den Stoff integrierten kleinen Lamellen, welche die Transmission direkt einfallender Lichtstrahlen ab einem vorgegebenem Höhenwinkel auch bei dünnen oder locker gewebten Stoffen verhindert, die Durchsicht jedoch nach unten für den Benutzer gewährleistet bleibt, so dass der Benutzer durch den Stoff hindurch ausreichende Durchsicht nach unten hat und dadurch die Außenumgebung wahrnehmen kann, wohingegen die Blendung durch direkt einfallende Sonnenstrahlung verhindert wird.The advantages of the invention are in particular that some of the existing ones Threads of the first type are arranged in a first direction or one have such thread cross-section that these first threads are comparatively have large cross-sectional dimensions in a direction that is perpendicular to the other material level, with the material level in particular is determined by the threads of the second type, which is transverse or perpendicular to the Threads of the first kind run. This from the plane of the second threads to the outside protruding ribs or webs running parallel to each other act like that small lamellae integrated in the fabric, which directly transmit the transmission Light rays from a given height angle even with thin ones or loosely woven fabrics, but looking down for the user remains guaranteed, so that the user through the fabric has sufficient visibility downwards and therefore the outside environment can perceive, whereas the glare from direct incidence Solar radiation is prevented.

Bevorzugt sind die rippenförmigen ersten Fäden oder Zusatzfäden auf einer Seite des Stoffes ausgebildet, und der Stoff wird für Sonnenschutzzwecke bevorzugt so verwendet, dass die Rippen oder Stege horizontal verlaufen und gegen den Lichteinfall gerichtet sind. Wenn dann - gemäß einer besonders bevorzugten Ausführungsform der Erfindung - unterhalb jeder Rippe die ersten Fäden einen vergrößerten Abstand voneinander aufweisen, so ist die Durchsicht nach unten weiter verbessert, wohingegen die Transmission der direkten Sonnenlichtstrahlen wirksam durch die wie Lamellen wirkenden Rippen verhindert ist. Der Stoff besitzt dann einen stark vom Einfallswinkel des Lichtes abhängigen Transmissionsgrad.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung können die betreffenden ersten Fäden mit mitlaufenden Zusatzfäden so verstärkt werden, bis die gewünschte Auskragung der Rippen aus der sonstigen Stoffebene bzw. der Ebene der zweiten Fäden verwirklicht ist. Die Rippen besitzen dann einen länglichen, flachen Querschnitt, der bevorzugt etwa senkrecht zur Ebene der zweiten Fäden ausgerichtet ist, der jedoch auch - erfindungsgemäß - zu dieser Ebene bzw. der sonstigen Stoffebene einen vorgegebenen Neigungswinkel einnehmen kann.The rib-shaped first threads or additional threads are preferably formed on one side of the fabric, and the fabric is preferably used for sun protection purposes such that the ribs or webs run horizontally and are directed against the incidence of light. If - according to a particularly preferred embodiment of the invention - the first threads are spaced apart from each other below each rib, the view downwards is further improved, whereas the transmission of direct sunlight rays is effectively prevented by the ribs, which act like lamellae. The material then has a transmittance that is strongly dependent on the angle of incidence of the light.
According to a further preferred embodiment of the invention, the relevant first threads can be reinforced with accompanying additional threads until the desired projection of the ribs from the other fabric level or the level of the second threads is realized. The ribs then have an elongated, flat cross section, which is preferably oriented approximately perpendicular to the plane of the second threads, but which, according to the invention, can also assume a predetermined angle of inclination with respect to this plane or the other fabric plane.

Besonders bevorzugt lassen sich die Rippen auch dadurch ausbilden, dass zusätzlich zu den in der Stoffebene verlaufenden ersten Fäden weiter zusätzliche erste Fäden angeordnet sind, die den rippenförmigen Querschnitt in der gewünschten Weise realisieren.The ribs can particularly preferably also be formed by additionally in addition to the first threads running in the fabric plane first threads are arranged which the rib-shaped cross section in the desired Realize wisely.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung lässt sich neben jeden n-ten ersten Faden im wesentlichen senkrecht zu der Stoffebene bzw. der Ebene der zweiten Fäden ein weiterer erster Faden zur Bildung der Rippen vorsehen.According to a further preferred embodiment of the invention, next to every nth first thread essentially perpendicular to the material plane or the level of the second threads another first thread to form the Provide ribs.

Bevorzugt lassen sich die zweiten Fäden in mehreren parallelen Fadenebenen vorsehen. Erfindungsgemäß ist es auch möglich, die zweiten Fäden aus transparentem Material herzustellen.The second threads can preferably be in several parallel thread planes provide. According to the invention, it is also possible to remove the second threads manufacture transparent material.

Zusätzlich sind auf einer Seite der zweiten Fäden weitere erste Fäden 8 vorgesehen, die jeweils neben einem der ersten Fäden 6 angeordnet sind und einen Querschnitt aufweisen, der in Richtung R senkrecht zu der aus den zweiten Fäden gebildeten Ebene länglich ausgebildet ist, um gegen direkte Sonneneinstrahlung ab einem vorgegebenem Höhenwinkel eine wirksame Lamellenwirkung und somit Beschattungswirkung zu verwirklichen. Die ersten Fäden 8 sind neben den ersten Fäden 6 angeordnet, sie lassen sich mit einer geeigneten Webart gegebenenfalls durch dünne Zusatzfäden mit den zweiten Fäden 4 verweben und befestigen. Die flachen, die Rippen bildenden Fäden 8 besitzen eine längere Querschnittsachse a und eine kürzere Querschnittsachse b. Die Fäden 8 sind so an den Stoff angeordnet, dass die längere Querschnittsachse a senkrecht zu der von den zweiten Fäden 4 definierten Ebene verläuft.Figure 3a shows another embodiment of the fabric, in which the first Threads 6 cross the second threads 4 vertically. Additionally are on one side of the second threads further first threads 8 are provided, each next to one of the first threads 6 are arranged and have a cross section which is shown in Direction R perpendicular to the plane formed from the second threads is designed to withstand direct sunlight from a given Elevation angle an effective slat effect and thus shading effect to realize. The first threads 8 are arranged next to the first threads 6, they can be made with a suitable weave, if necessary by thin Interweave and fasten additional threads with the second threads 4. The flat, the ribs forming threads 8 have a longer cross-sectional axis a and a shorter cross-sectional axis b. The threads 8 are arranged on the fabric that the longer cross-sectional axis a is perpendicular to that of the second Threads 4 defined level runs.

Figur 3b zeigt eine dem Stoff gemäß Figur 3a entsprechende Ausführungsform, bei der jedoch die die Rippen bildenden ersten Fäden 8 jeweils auf einem ersten Faden 8 angeordnet sind und mit ihrer längeren Querschnittsachse unter einen Winkel < 90° nach außen und unten gerichtet sind.FIG. 3b shows an embodiment corresponding to the fabric according to FIG. 3a, in which, however, the first threads 8 forming the ribs are each on a first Thread 8 are arranged and with their longer cross-sectional axis below are angled <90 ° outwards and downwards.

Figur 4 zeigt einen Querschnitt durch eine weitere Ausführungsform eines Stoffes, bei der wiederum die ersten Fäden 6 die zweiten Fäden 4 senkrecht kreuzen. Auf der einen Seite des Stoffes, die für Sonnenschutzzwecke der Lichteinstrahlung ausgesetzt werden soll, sind weitere erste Fäden 8 in erster Richtung vorgesehen, die beispielsweise durch geeignete Führung von Zusatzfäden 10 mit den zweiten Fäden verbunden sind und eine Rippenstruktur bilden, deren rippenförmige Querschnitte sich von der Ebene der zweiten Fäden weg nach außen und oben erstrecken.Figure 4 shows a cross section through a further embodiment of a Material, in which the first threads 6, the second threads 4 vertically cross. On one side of the fabric for sun protection purposes Should be exposed to light, there are further first threads 8 in the first Direction provided, for example, by suitable guidance of additional threads 10 are connected to the second threads and form a rib structure, whose rib-shaped cross sections differ from the plane of the second threads extend away outward and upward.

Figur 5 zeigt eine weitere Ausführungsform des erfindungsgemäßen Stoffes, bei dem zweite Fäden 4 in zwei parallelen Ebenen verlaufen, wobei erste Fäden 6 - in einer üblichen Webart - die zweiten Fäden 4 der einen Ebene kreuzen. Zusätzlich sind weitere erste Fäden 8 zwischen den regulären ersten Fäden 6 angeordnet. Diese zusätzlichen ersten Fäden 8 besitzen in Richtung R senkrecht zu der Ebene der zweiten Fäden einen langgestreckten, von der Stoffebene weg gerichteten Querschnitt und sind an den zweiten Fäden 4 befestigt.FIG. 5 shows a further embodiment of the substance according to the invention, in the second thread 4 run in two parallel planes, the first thread 6 - in a conventional weave - cross the second threads 4 of one level. In addition, there are further first threads 8 between the regular first threads 6 arranged. These additional first threads 8 have a vertical direction R to the plane of the second threads an elongated one, from the fabric plane away directed cross section and are attached to the second threads 4.

Zur Erzielung der gewünschten Sonnenschutzwirkung wird der erfindungsgemäße Stoff bei Rollos oder Raffrollos oder anderen Vorhängen so eingesetzt, dass die von den ersten Fäden gebildeten Rippen horizontal verlaufen, wohingegen die zweiten Fäden dann im wesentlichen vertikal ausgerichtet sind.To achieve the desired sun protection effect, the invention Fabric used for roller blinds or Roman blinds or other curtains that the ribs formed by the first threads run horizontally, whereas the second threads are then oriented substantially vertically.

Figur 6 zeigt eine weitere Ausführungsform des erfindungsgemäßen Stoffes, welche der Ausführungsform gemäß Figur 5 verwandt ist. Zweite Fäden 4 laufen in in parallelen Ebenen, wobei erste Fäden 6, 8 senkrecht zu den zweiten Fäden 4 verlaufen. Mehrere erste Fäden 6, 8 sind so angeordnet, dass ihr Querschnitt längs einer Geraden 4 liegt, wobei die Gerade 5 unter einem Winkel α< 90° schräg zu den Ebenen verläuft, welche durch die zweiten Fäden 4 aufgespannt werden. Die ersten Fäden 6, 8 bilden Rippen oder Lamellen, welche mittels Befestigungsfäden 20 an den zweiten Fäden 4 befestigt sind. Bei Verwendung des Stoffes gemäß den Figuren 5 und 6 als Behang einer Sonnenschutzeinrichtung, beispielsweise eines Rollos, lässt sich vorteilhafterweise erreichen, dass von außen auf die Rippen oder Lamellen auftreffende Sonnenstrahlen nicht auf direktem Wege in den Innenraum eines so beschatteten Raumes gelangen können, sondern an den Rippen des Stoffes absorbiert werden oder - besonders vorteilhaft - auch nach außen reflektiert werden, wenn geeignete Materialien für die zweiten Fäden 6, 8 verwendet werden, welche die Rippen bilden. Die Ausführungsform gemäß den Figuren 5 und 6 gestatten darüber hinaus auch, dass sich die von den zweiten Fäden 6, 8 gebildeten Rippen beispielsweise durch Längsverstellung der ersten Fäden 4 in ihrer Neigung entsprechend dem Sonnenstand oder den gewünschten Funktionen verändern lassen.FIG. 6 shows a further embodiment of the substance according to the invention, which the embodiment according to FIG. 5 is related. Second threads 4 run in in parallel planes, the first threads 6, 8 being perpendicular to the second threads 4 run. Several first threads 6, 8 are arranged so that their cross section lies along a straight line 4, the straight line 5 at an angle α <90 ° runs obliquely to the planes which are spanned by the second threads 4 become. The first threads 6, 8 form ribs or lamellae, which are fastened by means of fastening threads 20 are attached to the second threads 4. When using the 5 and 6 as a curtain of a sun protection device, for example, a roller blind, can advantageously be achieved by Sun rays hitting the outside of the ribs or slats are not directly Can get into the interior of such a shaded room, but are absorbed on the ribs of the fabric or - particularly advantageous - also be reflected to the outside if suitable materials for the second threads 6, 8 are used, which form the ribs. The embodiment 5 and 6 also allow that the ribs formed by the second threads 6, 8, for example, by Longitudinal adjustment of the first threads 4 in their inclination according to the Have the sun position or the desired functions changed.
