Description

Die Erfindung betrifft einen Vorhang zum wahlweisen Abdecken einer im wesentlichen drei- oder mehreckigen Fläche, insbesondere zum Verschatten einer Fensterfläche, insbesondere einen Faltenvorhang mit plissiertem Behangmaterial, nach dem Oberbegriff des Anspruches 1, wobei der Behang/die Behänge aber z. B. auch aus (Horizontal-)Lamellen od. dgl. bestehen können.The invention relates to a curtain for optionally covering a substantially triangular or polygonal surface, in particular for shading a window surface, in particular a pleated curtain with pleated curtain material, according to the preamble of claim 1, but the curtain / curtains z. B. can also consist of (horizontal) slats or the like.

Gattungsgemäße Vorhänge finden insbesondere bei nichtrechtwinkligen Fenster- oder Glastürflächen Anwendung, die z. B. dreieck- oder trapezförmig sind oder einen solchen Abschnitt aufweisen, und zwar insbesondere als sog. Faltstores, aber auch in anderen Ausgestaltungen (s. o.).Generic curtains are used in particular for non-right-angled window or glass door surfaces which, for. B. are triangular or trapezoidal or have such a section, in particular as so-called. Folding blinds, but also in other configurations (see above).

Von gespannten Faltstores spricht man, wenn das Behangmaterial von wenigstens einem Spannmittel in der Art eines Drahtes, einer Schnur od. dgl. durchsetzt ist, welches das Behangmaterial gegen erhebliche Bewegungen senkrecht zur Behangebene sichert. Gespannte Faltvorhänge können mithin auch an schräg zur Vertikalen verlaufenden Flächen und sogar an hiorizontalen Flächen als sog. Plafondanlagen verwendet werden, wie sie z. B. in Wintergärten vorkommen.One speaks of tensioned folding blinds if the curtain material has at least one tensioning device of the type Wire, a cord or the like is interspersed, which secures the curtain material against significant movements perpendicular to the curtain plane. Tensioned folding curtains can therefore also be used as so-called ceiling systems on surfaces that run at an angle to the vertical and even on horizontal surfaces. B. occur in winter gardens.

Aus der DE-GM 89 08 566 ist ein solcher gespannter Faltstore für eine trapezförmige Fläche bekannt, der eine feste untere Schiene sowie eine (der Trapezforn entsprechende) kürzere bewegliche obere Schiene aufweist, zwischen denen der Behang angeordnet ist, wobei das (die) Spannmittel mit seinem (ihrem) einen Ende an der beweglichen oberen Schiene befestigt ist (sind), und an seinem (ihren) anderen Ende durch die untere feste Schiene geführt ist (sind). Als Spannerzeuger dient (ggf. jeweils) ein am unteren Ende des Spannmittels angrenzendes Gewicht.From DE-GM 89 08 566 such a tensioned folding blind for a trapezoidal surface is known, which has a fixed lower rail and a (corresponding to the trapezoidal) shorter movable upper rail, between which the curtain is arranged, the (the) tensioning means is attached at one end to the movable upper rail, and at its other end is guided through the lower fixed rail. A weight adjoining the lower end of the clamping device serves as a tension generator.

Diese Spannungserzeugung ist insbesondere bei geöffnetem Vorhang unzweckmäßig, weil dann entsprechend lange Spannmittelabschnitte aus dem Vorhang heraushängen. Auch eignet sich diese Konstruktion nicht für relativ breite Vorhänge und/oder Vieleckflächen wie z. B. Fünfecke, wie sie sehr häufig als Bedarfsfall vorkommen.This generation of tension is particularly unsuitable when the curtain is open, because then correspondingly long sections of tensioning means hang out of the curtain. Also, this construction is not suitable for relatively wide curtains and / or polygonal areas such. B. pentagons, as they very often occur as a need.

Aus der DE-GM 89 09 836 ist ein gattungsmäßiger Drei-Schienen-Faltenvorhang bekannt, dessen Spannmittel unter Federkraft steht, und beim Öffnen des Vorhangs auf eine in der unteren festen Schiene angeordneten Wickelwelle gewickelt wird, in welcher eine vorgespannte Drehfeder angeordnet ist. Der Behang erstreckt sich zwischen der unteren festen Schiene und einer quer zu dieser in der Behangebene beweglichen Schiene, die in der geschlossenen Vorhangstellung an einer oberen festen Schiene anliegt.From DE-GM 89 09 836, a generic three-rail pleated curtain is known, the tensioning means of which is under spring force, and when the curtain is opened, it is wound on a winding shaft arranged in the lower fixed rail, in which a prestressed torsion spring is arranged. The curtain extends between the lower fixed rail and a rail movable transversely to the latter in the curtain plane, which abuts an upper fixed rail in the closed curtain position.

Da das Spannmittel bei einer solchen Ausbildung beim Öffnen und Schließen jeweils durch sämtliche Behangfalten gezogen werden muß, ergibt sich eine sehr hohe Reibung, die eine entsprechend große Betätigungskraft erfordert.Since the tensioning means must be pulled through all curtain folds when opening and closing such a design, there is a very high friction, which requires a correspondingly large actuating force.

Ein weiterer Nachteil dieses Faltstores besteht darin, daß bei zu verschattenden Flächen, die z. B. im oberen Teil aus einem Dreieck oder einem Trapez, und in ihrem unteren Teil aus einer rechtwinkligen Fläche bestehen, die die Wickelwelle aufnehmende Schiene fest sein muß, also auch bei geöffnetem Vorhang stets die betreffende Fläche durchsetzt.Another disadvantage of this folding blind is that in areas to be shaded, the z. B. in the upper part of a triangle or a trapezoid, and in its lower part consist of a rectangular surface that the winding shaft receiving rail must be fixed, so always passes through the surface in question even when the curtain is open.

Entsprechendes gilt auch für Vorhänge mit (Horizontal-)Lamellen oder andere Behangausgestaltungen, die zwar im Vergleich zu Faltstores seltener eingesetzt werden, indes auf dem Markt auch für insbesondere eine Verschattung von drei- oder mehreckigen Flächen, wie sie z. B./insbesondere bei Wintergärten od. dgl. häufig auftreten, eine erhebliche Bedeutung haben.The same applies to curtains with (horizontal) slats or other curtain designs, which are used less often than folding blinds, but also on the market for shading of triangular or polygonal surfaces, such as z. B./ especially in winter gardens or the like. Occur frequently, have a significant importance.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Vorhang zu schaffen, der unter Vermeidung der genannten und weitere Nachteile ein sowohl ästhetisch als auch funktionell befriedigendes Abschatten komplizierter (Fenster-)Geometrien ermöglicht, wobei die Reibung und damit die Betätigungskraft beim Öffnen und Schließen erheblich verringert und überdies eine Möglichkeit geschaffen werden soll, den Vorhang öffnen zu können, ohne daß sich dabei eine feste Schiene (nebst Behangmaterial) mitten durch die Fläche erstreckt. Außerdem soll es möglich sein, relativ breite Faltstores von z. B. 2 m Breite und mehr zu bilden, wie dieses bisher nicht möglich war.The object of the present invention is to provide a generic curtain which, while avoiding the mentioned and other disadvantages, enables shading of complicated (window) geometries which is both aesthetically and functionally satisfactory, the friction and thus the actuating force during opening and closing being considerably reduced and moreover, a possibility should be created to be able to open the curtain without a fixed rail (together with curtain material) extending through the middle of the surface. In addition, it should be possible to have relatively wide folding blinds of e.g. B. 2 m wide and more to form, as this was previously not possible.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved according to the invention by the characterizing features of claim 1. Preferred embodiments the invention are described in the subclaims.

Die Erfindung ist nachstehend unter Bezugnahme auf eine Zeichnung anhand von Ausführungsbeispielen weiter erläutert, bei denen der Vorhang als Faltenvorhang ausgebildet ist. Es zeigt:

The invention is further explained below with reference to a drawing using exemplary embodiments in which the curtain is designed as a fold curtain. It shows:
Fig. 1
a first embodiment of a fold curtain according to the invention;
Fig. 2
another embodiment of a pleated curtain according to the invention; and
3 to 6
different configuration options in a schematic representation.

Fig. 1 zeigt eine erste Ausführungsform eines erfindungsgemäßen Faltenvorhangs in seitlicher Draufsicht auf die abzudeckende Fläche. Ein (oberer) trapezförmiger erster Behang 1, dessen linker und rechter Seitenrand mit 1a bzw. 1b bezeichnet sind, ist mit seinem oberen Rand an einer beweglichen oberen ersten Schiene 2 und einer darunter liegenden Halteschiene 3 so aufgespannt, daß die Behangfalten horizontal und damit parallel zu den Schienen 2, 3 verlaufen.Fig. 1 shows a first embodiment of a fold curtain according to the invention in a side plan view of the surface to be covered. An (upper) trapezoidal first curtain 1, the left and right side edges of which are designated 1a and 1b, is stretched with its upper edge on a movable upper first rail 2 and an underlying holding rail 3 so that the curtain folds are horizontal and thus parallel run to the rails 2, 3.

Ein rechteckiger zweiter (unterer) Behang 5, der ebenfalls lediglich mit seinem linken und rechten Seitenrand 5a bzw. 5b angedeutet ist, ist in entsprechender Weise zwischen der Halteschiene 3 und einer beweglichen unteren zweiten Schiene 4 aufgespannt.A rectangular second (lower) curtain 5, which is also only indicated with its left and right side edges 5a and 5b, is stretched in a corresponding manner between the holding rail 3 and a movable lower second rail 4.

In der Schließstellung legt sich die erste bewegliche (obere) Schiene 2 an eine feste Anschlagschiene 6 an, die gleichzeitig als Aufhänge- und Führungselement dient. Unmittelbar an den linken Seitenrand 1a des trapezförmigen ersten Behangs 1 schließt sich eine Randschiene 7 an, die ebenfalls als Aufhänge- und Führungselement dient. Die Anschlagschiene 6 und die Randschiene 7 sind jeweils an Befestigungspunkten 6a und 7a in geeigneter Weise am Rand der zu verschattenden Fläche befestigt, während die Halteschiene 3 über Aufhängungen 8 an den festen Schienen 6 und 7 hängt.In the closed position, the first movable (upper) rail 2 lies against a fixed stop rail 6, which also serves as a suspension and guide element. Right away an edge rail 7 adjoins the left side edge 1a of the trapezoidal first curtain 1, which also serves as a suspension and guide element. The stop rail 6 and the edge rail 7 are each fastened at fastening points 6a and 7a in a suitable manner on the edge of the surface to be shaded, while the holding rail 3 hangs on the fixed rails 6 and 7 via suspensions 8.

Dabei sei darauf verwiesen, daß der Faltstore gemäß Fig. 1 ersichtlich auch lediglich für eine Fläche gemäß dem Behang 1 bestimmt sein könnte. In diesem Falle würde (lediglich) die Schiene 4 (nebst zweiten Behang 5 und dem ihm zugeordneten Spannmittel (4)) entfallen.It should be pointed out here that the folding blind according to FIG. 1 could also be intended only for a surface according to the curtain 1. In this case, the rail 4 (along with the second curtain 5 and the tensioning means (4) assigned to it) would be omitted.

Die Vertikalbewegung der Schiene 2 wird zunächst einmal durch ein als Spannschnur ausgebildetes Spannmittel 11, das an seinem oberen Endabschnitt 11' im Bereich seines parallel zum schrägen linken Seitenrand 1a des ersten Behangs 1 verlaufenden Schrägabschnitt 11'' befestigt ist, und zwar über eine Spannfeder 12 in der schrägen Randschiene 7, und das an seinem anderen Ende 11''' an der Schiene 3 befestigt ist, wobei das Spannmittel 11 an Umlenkstellen 20 in den Schienen 6 und 2 so umgelenkt wird, daß seine Abschnitte 11' und 11'' parallel verlaufen. Diese Anordnung hat zur Folge, daß das Spannmittel 11 des Behangs 1 beim Öffnen und Schließen nicht durch alle Falten gezogen werden muß, so daß eine erheblich geringere Betätigungskraft ausreicht als bei bekannten Faltstores, bei denen das Spannmittel unten aufgenommen wird.The vertical movement of the rail 2 is first of all by means of a tensioning means 11 designed as a tension cord, which is fastened to its upper end portion 11 'in the region of its inclined portion 11' 'running parallel to the inclined left side edge 1a of the first curtain 1, specifically via a tension spring 12 in the inclined edge rail 7, and which is attached at its other end 11 '' 'to the rail 3, the clamping means 11 being deflected at deflection points 20 in the rails 6 and 2 such that its sections 11' and 11 '' are parallel run. The result of this arrangement is that the tensioning means 11 of the curtain 1 does not have to be pulled through all the folds when opening and closing, so that a considerably lower actuating force is sufficient than in the case of known folding blinds, in which the tensioning means is received at the bottom.

Weiterhin wird die Schiene 2 (und damit der Behang 1) von einem zweiten Spannmittel 9 geführt, das in zwei symmetrischen Abschnitten jeweils zweifach L-förmig über Rollen geführt an seinen Enden in der Anschlagschiene 6 gehalten ist. An einer geeigneten Stelle (z.B. hier in der Halteschiene 3) sorgt eine Spannfeder 10 für die erforderliche Vorspannung der Spannschnur 9.Furthermore, the rail 2 (and thus the curtain 1) is guided by a second clamping means 9, which is held in two symmetrical sections in each case in an L-shaped manner by rollers at its ends in the stop rail 6. At a suitable point (for example here in the holding rail 3), a tension spring 10 ensures the required pretension the tension cord 9.

In diesem Zusammenhang sei bemerkt, daß einzelne oder alle Spannmittel 9, 11 und Aufhängungen 8 im Bereich der Vorhangfläche so geführt sind, daß sie die einzelnen Falten des Vorhangs jeweils durch eine Reihe von Durchgangsöffnungen durchsetzen. Je nach Gewicht und Größe des Behangs können die Durchgangsöffnungen mit einer Randverstärkung versehen sein, um Reibung und Verschleiß zu vermindern.In this connection it should be noted that individual or all tensioning means 9, 11 and suspensions 8 are guided in the area of the curtain surface in such a way that they each penetrate the individual folds of the curtain through a series of through openings. Depending on the weight and size of the curtain, the through openings can be provided with edge reinforcement to reduce friction and wear.

Weiterhin sei darauf verwiesen, da der gegenseitige Abstand a zwischen benachbarten, parallelen Abschnitten der Spannmittel (maximal) etwa 50 cm beträgt.It should also be noted that the mutual distance a between adjacent, parallel sections of the clamping means (maximum) is approximately 50 cm.

Die zweite (untere) bewegliche Schiene 4 ist in Fig. 1 in halbgeöffneter Stellung zwischen ihrer Öffnungsstellung (benachbart zur Halteschiene 3) und ihrer Schließstellung (benachbart zu den Anschlag- bzw. Befestigungspunkten 13) dargestellt. Die Schiene 4 wird bei ihrer vertikalen Auf- und Abbewegung in entsprechender Weise wie die Schiene 2 durch ein Spannmittel 14 geführt, das - ausgehend von (unteren) Befestigungspunkten 13 - über in der Schiene 4 angeordnete Umlenkrollen zur Mittelschiene 3 verläuft und von dort angeordneten Spannfedern 15 unter Spannung gehalten werden.The second (lower) movable rail 4 is shown in Fig. 1 in a half-open position between its open position (adjacent to the holding rail 3) and its closed position (adjacent to the stop or attachment points 13). The rail 4 is guided in its vertical up and down movement in the same way as the rail 2 by a clamping means 14 which - starting from (lower) fastening points 13 - runs over guide rollers arranged in the rail 4 to the central rail 3 and from there arranged tension springs 15 are kept under tension.

Je nach den örtlichen Gegebenheiten kann es zweckmäßig sein, aus ästhetischen und/oder funktionellen Gründen noch eine weitere (untere) Anschlagschiene 16 anzuordnen. Aus den genannten Gründen ist es des weiteren vorteilhaft, zwischen der Randschiene 7 und der Halteschiene 3 ein Spannmittel 18 vorzusehen. Dieses eröffnet die Möglichkeit für die Schaffung sehr breiter Faltstores, wie sie bisher nicht herstellbar waren.Depending on the local conditions, it may be expedient to arrange a further (lower) stop rail 16 for aesthetic and / or functional reasons. For the reasons mentioned, it is also advantageous to provide a clamping means 18 between the edge rail 7 and the holding rail 3. This opens up the possibility of creating very wide folding blinds that were previously not possible.

Wie bereits erwähnt, kann eine weitere Ausführungsform eines erfindungsgemäßen Faltenvorhangs lediglich einen dreieck- oder trapezförmigen Behangteil 1 und keinen rechteckförmigen Behangteil 5 aufzeigen, wie in Fig. 6 schematisch dargestellt ist. Eine derartige Ausführungsform ist für einen Fachmann in naheliegender Weise ersichtlich, da die Schienen 2 bzw. 4, welche die Behänge 1 bzw. 5 halten, funktionell unabhängig voneinander von den Spannschnüren 9, 11 und 14 parallel beweglich geführt werden und somit auch jeweils einzelnen (mit nur einem Behang) angeordnet sein können.As already mentioned, a further embodiment of a pleated curtain according to the invention can only show a triangular or trapezoidal curtain part 1 and no rectangular curtain part 5, as is shown schematically in FIG. 6. Such an embodiment is obvious to a person skilled in the art, since the rails 2 and 4, which hold the curtains 1 and 5, are functionally guided independently of one another by the tensioning cords 9, 11 and 14 and thus also individually ( with only one curtain) can be arranged.

Fig. 2 zeigt eine andere Ausführungsform eines Faltenvorhangs, bei der ein (oberer) trapezförmiger erster Behang 1 zwischen einer beweglichen oberen ersten Schiene 2 und einer beweglichen unteren zweiten Schiene 4 aufgespannt ist. Ein (unterer) rechteckiger zweiter Behang 5 ist in entsprechender Weise zwischen der beweglichen unteren Schiene 4 und einer darunterliegenden festen Halteschiene 3 aufgespannt. Die beiden Behänge 1 und 5 sind lediglich mit ihren linken bzw. rechten Seitenrändern 1a bzw. 1b und 5a bzw. 5b angedeutet.FIG. 2 shows another embodiment of a pleated curtain, in which an (upper) trapezoidal first curtain 1 is stretched between a movable upper first rail 2 and a movable lower second rail 4. A (lower) rectangular second curtain 5 is stretched in a corresponding manner between the movable lower rail 4 and an underlying fixed holding rail 3. The two curtains 1 and 5 are only indicated with their left and right side edges 1a and 1b and 5a and 5b.

Die zweite Schiene 4 ist in vertikaler Richtung verschieblich, wobei sie zwischen der in Fig. 2 dargestellten Schließstellung (der Behangteil 5 überdeckt die zu verschattende rechteckförmige Fläche) und einer Öffnungsstellung (die Behangfalten sind kompakt zusammengeschoben) hin- und herbewegt werden kann. Die Schließstellung der zweiten Schiene 4 wird durch den unteren (linken) Endabschnitt der Randschiene 7 und einen an der Spannschnur 14 unbeweglich befestigten Stopper 19 bestimmt. In der Öffnungsstellung liegt die zweite Schiene 4 unmittelbar benachbart zur Halteschiene 3. Die Halteschiene 3 ist in geeigneter Weise am unteren Rand der zu verschattenden Fläche befestigt.The second rail 4 is displaceable in the vertical direction, whereby it can be moved back and forth between the closed position shown in FIG. 2 (the curtain part 5 covers the rectangular surface to be shaded) and an open position (the curtain folds are compactly pushed together). The closed position of the second rail 4 is determined by the lower (left) end section of the edge rail 7 and a stopper 19 immovably fastened to the tension cord 14. In the open position, the second rail 4 lies directly adjacent to the holding rail 3. The holding rail 3 is fastened in a suitable manner to the lower edge of the surface to be shaded.

Bei dieser Ausgestaltung ist das Spannmittel 11 nicht an der zweituntersten Schiene 4 befestigt, sondern durch diese (unter Umlenkung) hindurch und nach unten zur festen Halteschiene 3 geführt. Hierdurch ist es möglich, die beweglichen Schienen 2, 4 im Öffnungszustand aus dem (mittleren) Bereich der Fläche herauszubewegen und völlig freie Durchsicht zu schaffen.In this embodiment, the clamping means 11 is not fastened to the second lowermost rail 4, but is guided through it (under deflection) and down to the fixed holding rail 3. This makes it possible to move the movable rails 2, 4 out of the (central) area of the surface in the open state and to provide a completely clear view.

Die Vertikalbewegung der zweiten Schiene 4 wird außerdem durch einen Spannschnur 14 geführt, die in zwei Abschnitten jeweils zweifach L-förmig über Umlenkrollen geführt ist und einerseits in einer Anschlagschiene 6 sowie einer Randschiene 7 und andererseits in der Halteschiene 3 gehalten ist. In der Halteschiene 3 sorgt eine Spannfeder 15 für die erforderliche Vorspannung der Spannschnur 14.The vertical movement of the second rail 4 is also guided by a tension cord 14, which is guided in two sections in each case twice in an L-shape over deflecting rollers and is held on the one hand in a stop rail 6 and an edge rail 7 and on the other hand in the holding rail 3. In the holding rail 3, a tension spring 15 ensures the required pretensioning of the tension cord 14.

Die erste Schiene 2 ist in Fig. 2 ebenfalls in Schließstellung (benachbart zur Anschlagschiene 6) dargestellt, in der der Behang 1 den oberen Abschnitt der zu verschattenden, (trapezförmigen) Fläche überdeckt. In ihrer Öffnugsstellung liegt die erste Schiene 2 unmittelbar benachbart zur oben beschriebenen, parallel beweglich geführten, zweiten Schiene 4. Die Schiene 2 wird bei ihrer vertikalen Auf- und Abbewegung in entsprechender Weise wie die Schiene 4 durch Spannmittel 11 und 9 geführt, wobei letzteres - ausgehend von der (oberen) Anschlagschiene 6 - über in der ersten Schiene 2 angeordnete Umlenkrollen zur Halteschiene 3 verläuft und von einer dort angeordneten Spannfeder 10 unter Spannung gehalten wird. Die Spannschnüre 9 verlaufen hierbei außerdem an Durchlaufpunkten 17 durch die zweite Schiene 4, die zwischen der ersten Schiene 2 und der Halteschiene 3 angeordnet ist.The first rail 2 is also shown in FIG. 2 in the closed position (adjacent to the stop rail 6), in which the curtain 1 covers the upper section of the (trapezoidal) surface to be shaded. In its open position, the first rail 2 is immediately adjacent to the above-described, parallel movably guided second rail 4. The rail 2 is guided in its vertical up and down movement in a manner corresponding to the rail 4 by clamping means 11 and 9, the latter - proceeding from the (upper) stop rail 6 - via deflection rollers arranged in the first rail 2 to the holding rail 3 and held under tension by a tension spring 10 arranged there. The tension cords 9 also run at pass points 17 through the second rail 4, which is arranged between the first rail 2 and the holding rail 3.

Die Fig. 3 bis 6 zeigen beispielhaft und schematisch einige Konfigurationsmöglichkeiten des erfindungsgemäßen Faltenvorhangs. Fig. 3 zeigt einen symmetrischen Faltenvorhang, dessen trapezförmiger Behang 1 von zwei symmetrischen, schrägen Behangkanten 1a bzw. Randschienen 7 begrenzt ist.3 to 6 show examples and schematically some configuration options of the folding curtain according to the invention. 3 shows a symmetrical pleated curtain, whose trapezoidal curtain 1 is delimited by two symmetrical, oblique curtain edges 1a or edge rails 7.

Fig. 4 zeigt eine Vorhangforn, die dadurch erhalten wird, daß ein erfindungsgemäßer Faltenvorhang (Behangflächen 1 und 5) mit einem darunter angeordneten, trapezförmigen Faltenvorhang kombiniert wird, oder aber dadurch, daß zwei erfindungsgemäße Faltenvorhänge miteinander kombiniert werden, wobei dann die mittlere (rechteckförmige) Behangfläche 5 entweder von einer oder von zwei beweglichen Schienen 4 geöffnet und geschlossen wird.Fig. 4 shows a curtain shape, which is obtained by combining a pleated curtain according to the invention (curtain surfaces 1 and 5) with a trapezoidal pleated curtain arranged below it, or by combining two pleated curtains according to the invention, with the middle (rectangular ) Curtain surface 5 is opened and closed either by one or by two movable rails 4.

Der erfindungsgemäße Faltenvorhang kann in jeder beliebigen Schräglage bis zur horizontalen Anordnung verwendet werden, wobei dann ggf. weitere Spannschnüre vorzusehen wären, um ein Durchhängen des Behangs zu vermeiden.
