Abstract

Awning with a canopy consisting of several strips (18) extending in the direction of extension which are rolled up on one and the same canopy roller. The longitudinal edges of the strips (418, 518, 618) can overlap one another, and the strips (418, 518) can be attached on the canopy roller (13, 113), offset with respect to one another in the circumferential direction thereof, while being connectible to one another along their longitudinal edges by the use of a fastening device such as a bristle trim or the like (23, 24), or with the edges adjacent each other without overlapping, whereby the edges can be released or separated by the application of wind pressure.

Description

Die Erfindung betrifft eine Markise, wie sie mit einer von annähernd horizontal bis annähernd vertikal abschwenkbaren flexiblen Bespannung mit Hilfe eines geeigneten Gestells an einem Baukörper befestigt ist, und bei der die Bespannung aus mehreren Streifen besteht.The invention relates to an awning as it is attached to a structure with a flexible covering that can be swung from approximately horizontal to approximately vertical with the aid of a suitable frame, and in which the covering consists of several strips.

Eine solche Markise ist schon verschiedentlich vorgeschlagen worden. So zeigt die CH-A-274.744 einen Sonnenstoren, bei dem an zwei auf der Tuchwelle aufrollbaren Stoffgurten die querverlaufenden Bespannungsstreifen über einen Teil ihrer.Breite im Abstand voneinander befestigt sind, während der nach aussen weisende Teil der Streifen frei nach unten hängt. Eine solche Konstruktion ist verhältnismässig kompliziert, bietet sowohl beim Auf- wie beim Abrollen Probleme mit den herabhängenden Streifen und konnte sich daher nicht durchsetzen.Such an awning has been proposed on various occasions. For example, CH-A-274.744 shows a sun blind in which the transverse covering strips are fastened over a part of their width on two fabric belts that can be rolled up on the fabric shaft, while the outward-facing part of the strips hangs freely downwards. Such a construction is relatively complicated, has problems with the hanging strips when it is rolled up and unrolled, and was therefore not able to assert itself.

Die Bespannung verläuft in aller Regel zwischen einem Ausfallprofil, das an Gelenkarmen, Fallarmen oder dergleichen befestigt ist, und einer Tuchwelle, auf der sie aufrollbar ist. Im abgerollten Zustand ist die Bespannung dem Winddruck ausgesetzt, der nicht nur eine hohe Reissfestigkeit der Bespannung, sondern auch eine massive und mithin schwerfällig erscheinende konstruktive Ausbildung des Gestells, insbesondere der Gelenkarme oder dergleichen Ausstellmittel verlangt, was sich auch in hohen Herstellungs- kosten niederschlägt.The covering usually runs between a drop profile, which is attached to articulated arms, drop arms or the like, and a fabric shaft, on which it can be rolled up. In the unrolled state, the covering is exposed to wind pressure, which requires not only a high tensile strength of the fabric, but also a massive, and hence cumbersome appearing structural design of the frame, in particular of the link arms or the like raising means, which is reflected creation cost even at high H .

Man hat daher auch schon die Aufteilung einer grösseren Bespannungsfläche in mehrere kleinere Einzelmarkisen vorgeschlagen, z.B. in der FR-A-829.881 für eine um eine Gebäudeecke reichende Markise, doch ist eine solche Konstruktion wegen der Notwendigkeit einer Mehrzahl von Tuchwellen mit eigenem Antrieb und Ausstellmitteln ausserordentlich aufwendig.Therefore, it has also been the division of a larger B espannungsfläche proposed in several smaller individual awnings, for example, in FR-A-829881 is for reaching a building corner awning, but such a design because of the need for a plurality of cloth waves with their own initiative and Ausstellmitteln extraordinarily complex.

Die Erfindung hat sich nun zur Aufgabe gestellt, eine Markise zu schaffen, die trotz verhältnismässig leichter Konstruktion auch stärkeren Windboen standhalten kann und die erwähnten Nachteile bekannter Markisen vermeidet. Dies gelingt erfindungsgemäss dadurch, dass die Streifen zwischen Ausfallprofil und Tuchwelle verlaufen und auf ein und derselben Tuchwelle aufrollbar sind.The invention has now set itself the task of creating an awning that can withstand stronger wind gusts despite relatively light construction and avoids the disadvantages of known awnings mentioned. This is achieved according to the invention in that the strips run between the drop profile and the fabric shaft and can be rolled up on one and the same fabric shaft.

Eine derart ausgebildete Bespannung unterscheidet sich im ausgespannten bzw. ausgefahrenen Zustand opitsch kaum von den einstückig ausgebildeten Bespannungen. Bei Windangriff öffnen sich die Schlitze zwischen den Streifen mehr oder weniger weit und lassen die bewegte Luft grossteils passieren, so dass der noch verbleibende, auf die Streifen drückende Luftstau sehr gering ist. Die somit erheblich geringer belastete Bespannung kann daher leichter ausgeführt sein, was auch für das Gestell bzw. die Ausstellmit- tel zutrifft. Dadurch werden auch optisch leicht erscheinende Konstruktionen möglich, die infolge ihrer geringen Dimensionierung noch an beengten Stellen montierbar sind, wodurch sich die Herstellkosten vermindern. Bei einer Beschädigung der Bespannung sind lediglich die beschädigten Streifen zu ersetzen.A cover designed in this way hardly differs from the one-piece cover in the extended or extended state. In the event of a wind attack, the slits between the strips open more or less and allow the moving air to pass through for the most part, so that the remaining air congestion that presses on the strips is very low. The thus considerably less loaded cover can therefore be made lighter, which usstellmit- for the frame or the A true tel. This also makes them appear optically ning constructions possible, which due to their small dimensions can still be installed in confined spaces, which reduces the manufacturing costs. If the fabric is damaged, only the damaged strips have to be replaced.

Die Lagerhaltung von Bespannungen verschiedener Grösse und Farbzusammenstellungen ist umständlich und aufwendig. Die Streifenform bietet nun die Möglichkeit, die jeweils erforderliche Bespannungsbreite aus - gegebenenfalls sogar verschieden.breiten - Einzelstreifen zusammenzustellen. Zudem kann die Farbenwahl und deren Folge den Wünschen der Kunden entsprechend variiert werden.The storage of clothing of different sizes and color combinations is cumbersome and time-consuming. The strip shape now offers the possibility of putting together the required covering width from individual strips, if necessary even different widths. In addition, the choice of colors and their sequence can be varied according to the wishes of the customers.

Fig.1 zeigt schematisch eine Rollblende bzw. Markise 11, deren Bespannung 17 einerends an der Tuchwelle 13 und anderends an einem Ausfallprofil 16 befestigt ist. Die Tuchwelle 13 ist in bekannter Weise an (nicht dargestellten) Tragelementen drehbar gelagert und betätigbar. An Schwenklagern 15 sind Gelenkarme 14 angelenkt, die das Ausfallprofil 16 tragen.1 shows schematically a roller blind or awning 11, the covering 17 of which is attached on one end to the fabric shaft 13 and the other on a drop profile 16. The cloth shaft 13 is rotatably mounted and actuated in a known manner on (not shown) support elements. Articulated arms 14 which carry the drop profile 16 are articulated on pivot bearings 15.

Die mithin einerseits vom Ausfallprofil 16 und andererseits von der Tuchwelle 13 getragene Bespannung 17 aus flexiblem Textilmaterial ist in Streifen 18 aufgeteilt. Die Streifen 18 können gleich breit sein oder, wie im Beispiel, unterschiedliche Breiten haben. Die Striefen 18 verlaufen in Abrollrichtung. Im Ruhezustand berühren einander die Längsränder 10 zweier benachbarter Streifen.The covering 17 made of flexible textile material, which is carried on the one hand by the drop profile 16 and on the other hand by the fabric shaft 13, is divided into strips 18. The strips 18 can be the same width or, as in the case game, have different widths. The S dripping 18 run in the rolling direction. In the idle state, the longitudinal edges 10 of two adjacent strips touch each other.

Auch nach Fig.2 können die Streifen 18 in einer Ebene so dicht nebeneinander angeordnet sein, dass die Längsränder 10 geschlossen sind. Jeder Streifen 18,18'ist am Ausfallprofil 16 vorzugsweise mittig befestigt, so dass sich die Längskanten 10 der Streifen 18'bei Windbelastung von unten unter Ausbildung von Schlitzen 30 aufwölben können. Die Befestigung kann auch auf dem der Hauptwindrichtung zugekehrten Längsrand jedes Streifens erfolgen; stabiler ist jedoch eine Befestigung an wenigstens zwei Stellen der Stirnenden der Streifen mittels einer Leiste, eines Klemmprofils oder dergleichen.According to FIG. 2, the strips 18 can be arranged so closely next to one another in one plane that the longitudinal edges 10 are closed. Each strip 18, 18 ′ is preferably fastened in the center of the drop profile 16, so that the longitudinal edges 10 of the strips 18 ′ can bulge out from below with the formation of slots 30 when the wind is loaded. The attachment can also be carried out on the longitudinal edge of each strip facing the main wind direction; However, it is more stable to fasten it to at least two points on the ends of the strips by means of a strip, a clamping profile or the like.

Für die Befestigung der Stoffstreifen 18'sind im Ausfallprofil 16 in - den Streifenbreiten entsprechenden Abständen - Löcher 20 vorgesehen, die zum Festhalten je eines Druckknopfes 21 an den Streifen 18,18'in bekannter Weise mit Haltefedern 22 versehen sein können.Selbstverständlich ist jede andere Konstruktion eines solchen Schnellverschlusses möglich. Bei grossen Windstärken ist jedoch eine derartig federnde Befestigung gegebenenfalls nicht sicher genug, so dass eine im Verriegelungszustand unlösbare Verbindung zweckmässiger ist. Zu diesem Zweck kann das verdickte Ende des Druckknopfs 21 zusätzlich in das breite Ende einer Schlüssellochöffung eingeführt werden, die in einem Schieber am Ausfallprofil 16 angeordnet ist, worauf der Schieber so verschoben wird, dass der schmälere Teil der Schlüssellochöffnung den Hals des Druckknopfs 21 unterhalb des verdickten Endes umgreift und so festhält.Holes 20 are provided in the drop profile 16 for fastening the fabric strips 18 'at intervals corresponding to the strip widths, which can be provided with retaining springs 22 in a known manner in order to hold a push button 21 each on the strips 18, 18'. Of course, any other one Construction of such a quick release is possible. In the case of large winds, however, such a resilient fastening may not be secure enough, so that a connection which cannot be released in the locked state is more appropriate. For this purpose, the thickened end of the push button 21 can also be wide End of a keyhole opening are inserted, which is arranged in a slide on the drop profile 16, whereupon the slide is moved so that the narrower part of the keyhole opening engages around the neck of the push button 21 below the thickened end and thus holds.

Um auch bei sehr geringer Steifheit der Streifen 18 schon bei geringem Luftzug ein Flattern zu vermeiden, können die Längsränder der Streifen 18 mit unter Druckbelastung sich öffnenden Einrichtungen, wie z.B. einer Vielzahl ineinander greifender, elastischer Widerhäkchen, reissverschlussartig verbind- bzw. lösbarer Formschlussverbindungen oder dergleichen versehen sein.In order to avoid fluttering even with slight draft, even with very low rigidity of the strips 18, the longitudinal edges of the strips 18 can be opened with devices that open under pressure, such as e.g. a large number of interlocking, elastic barbs, zipper-like connectable or detachable form-fitting connections or the like.

Auch kann der Rand der Stoffstreifen 18 beispielsweise mit einem Borstenstreifen 23 versehen sein, wobei die Borsten einander benachbarter Stoffstreifen 18 ineinandergreifen, dem Oeffnen der Schlitze einen gewissen Widerstand entgegensetzen und auf diese Weise ein Flattern bei geringer Windstärke vermeiden.The edge of the fabric strips 18 can also be provided, for example, with a bristle strip 23, the bristles of adjacent fabric strips 18 interlocking, opposing the opening of the slots with a certain resistance and in this way avoiding fluttering in low winds.

Die Streifen 18' können auch zwischen den Längsrändern einander benachbarter Stoffstreifen durch jeweils eine Verbindungsnaht mit elastisch dehnbaren Fäden 24,insbesondere aus elastischem Polyurethan-Kunststoff, miteinander verbunden sein, die ebenfalls eine bestimmte Gegenkraft gegen ein Oeffnen der Schlitze 30 ergibt. Die Verwendung von Kunststoff empfiehlt sich deshalb, weil Naturgummi bei Sonnenbestrahlung allzu schnell altert. Falls die von einer über die ganze Streifenlänge reichenden Naht erzielbare Schliesskraft zu gross sein sollte, ist es auch möglich, die Naht nur absatzweise, also mit Unterbrechungen auszuführen.The strips 18 'can also be connected to one another between the longitudinal edges of mutually adjacent strips of fabric by a connecting seam with elastically stretchable threads 24, in particular made of elastic polyurethane plastic, which likewise gives a certain counterforce against opening the slots 30. The usage of plastic is recommended because natural rubber ages too quickly when exposed to sunlight. If the closing force that can be achieved by a seam extending over the entire length of the strip is too great, it is also possible to carry out the seam only intermittently, ie with interruptions.

An den Enden über die Breite der Streifen 18 verlaufende Nähte können zur Befestigung der Bespannung am Ausfallprofil 16 dienen, wobei allerdings auch eine im wesentlichen punktförmige Verankerung mittels Gummifäden möglich ist. Durch solch eine elastische Verankerung können die Streifen 18 besonders weit voneinander abheben, so dass eine ausgezeichnete Luftdurchlässigkeit der Bespannung erzielbar ist. Andererseits bietet die Verankerung mittels des Schnellverschlusses 20-22 bestimmte Vorteile bei der individuellen Zusammenstellung von Bespannungen, die so rasch zu der gewünschten Breite und Farbmusterung leicht ausgetauscht werden können.Seams at the ends across the width of the strips 18 can be used to fasten the covering to the drop profile 16, although an essentially point-like anchoring by means of rubber threads is also possible. By means of such an elastic anchoring, the strips 18 can lift off from one another particularly far, so that excellent air permeability of the covering can be achieved. On the other hand, the anchoring by means of the quick-release fastener 20-22 offers certain advantages when it comes to the individual arrangement of coverings, which can be quickly exchanged for the desired width and color pattern.

Gemäss Fig.3 können die in Abrollrichtung verlaufenden Streifen 418,518 an der Tuchwelle 113 mit ihren Enden in zwei Nuten 36,37 verlaufen, die entlang des Tuchwellenmantels in Umfangsrichtung versetzt angeordnet und mit Hilfe von Klemmstäben bzw. Einsatzstücken 40,41 befestigt sind. Entsprechend sind die anderen Enden der Streifen 418,518 in zwei im Ausfallprofil 416 nebeneinander verlaufenden Nuten 38,39 mit Hilfe von Klemmstäben bzw. Einsatzstücken 42,43 befestigt. Der Abstand der paarweise angeordneten Nuten 36,37 und 38,39 voneinander ist zweckmässig so klein gewählt, dass die Streifen 418,518 im ausgefahrenen Zustand dicht übereinander liegen.According to FIG. 3, the strips 418, 518 running in the unrolling direction can run with their ends in two grooves 36, 37 on the fabric shaft 113, which are offset in the circumferential direction along the fabric shaft jacket and are fastened with the aid of clamping bars or inserts 40, 41. Correspondingly, the other ends of the strips 418, 518 are in two that run side by side in the drop profile 416 Grooves 38.39 fastened with the aid of clamping rods or inserts 42.43. The spacing of the grooves 36, 37 and 38, 39 arranged in pairs is expediently chosen to be so small that the strips 418, 518 lie one above the other in the extended state.

Wenn die Längsränder der Streifen 418,518 sich überlappen, was die Draufsicht gemäss Fig.4a zeigt, ist es zweckmässig, wenn die Abstände der Nut 36 von 37 einerseits, und der Nut 38 von 39 andererseits einander entsprechen, damit Streifen standardisierter Länge zum Einsatz kommen können.Da die obenliegenden Streifen 518 wegen des geringfügig grösseren Wickelradius immer etwas weniger Umdrehungen zu ihrer Aufrollung benötigen als die unteren Streifen 418, ist es zweckmässig, sie am Ausfallprofil elastisch zu lagern, z.B. einen Längenausgleich durch Einbau eines Gummibandes 45 oder einer nicht dargestellten Feder, vorzugsweise nahe des Ausfallprofils 16,416 vorzusehen.If the longitudinal edges of the strips 418, 518 overlap, which is shown in the top view according to FIG. 4 a, it is expedient if the distances between the groove 36 of 37 on the one hand and the groove 38 of 39 on the other hand correspond to one another so that strips of standardized length can be used .Because the strips 518 on top always need a little less revolutions to wind them up than the lower strips 418 due to the slightly larger winding radius, it is advisable to mount them elastically on the drop profile, e.g. provide a length compensation by installing a rubber band 45 or a spring, not shown, preferably near the drop profile 16,416.

Wie Fig.4b zeigt, können einander überlappende Streifen 618 auch in nur einer Nut in der Tuchwelle bzw.im Ausfallprofil befestigt werden, wobei der zu befestigende Endbereich jedes Streifens 618 sich gegenüber dessen eigentlicher Breite verjüngt. Dabei können allerdings Probleme mit der mangelnden Spannung der Längsränder auftreten.As FIG. 4b shows, overlapping strips 618 can also be fastened in only one groove in the fabric shaft or in the drop profile, the end region of each strip 618 to be fastened tapering in relation to its actual width. However, problems with the lack of tension in the longitudinal edges can occur.

Normale Stoffstreifen würden zwar auf der Tuchwelle und dem Ausfallprofil satt nebeneinander liegen, in der Mitte aber klaffen, was bei einer Streifenbreite von 200 mm und einer ausgefahrenen Länge von 300 cm bei üblichen Markisenstoffen Schlitze 30 von 1-3 cm ergibt. Dadurch fallen störende Licht- bzw. Sonnenstreifen durch die Bespannung, die unschön aussieht, wie aus Fig.6 ersichtlich ist.Normal strips of fabric would admittedly on the cloth shaft and the drop profile is snugly next to each other, but gap in the middle, which with a strip width of 200 mm and an extended length of 300 cm results in slits 30 of 1-3 cm with conventional awning fabrics. As a result, annoying streaks of light or sunshine fall through the covering, which looks unattractive, as can be seen in FIG. 6.

Dieses Problem kann z.B. gemäss Fig.7 dadurch gelöst werden, dass die Längsränder der Streifen 18 gegenüber ihren Mittelzonen dadurch unter Zugspannung gehalten werden, dass der für den Einschub der Klemmstäbe bzw. Einsatzstücke 40 bestimmte Hohlsaum 48 konvex ausgebildet wird, so dass im ausgefahrenen, gespannten Zustand die Randzonen etwas kürzer sind als die Mittelzonen. Es können aber auch die Streifen 18 quer zur Roll- oder Spannrichtung stabilisiert werden. Dies kann z.B. durch quer verlaufende Versteifungseinlagen oder durch die Vewendung dehnungsfreien Textilmaterials, beispielsweise Glasfasergewebe, geschehen, wodurch der Schrumpf der Streifen in Querrichtung - bei Zugbeanspruchung in Längsrichtung - verhindert oder zumindest klein gehalten werden kann. Es können auch im Verhältnis zu den Längsfäden sehr steife Querfäden verwendet werden, um die Querstabilität zu verbessern.This problem can e.g. 7 can be solved in that the longitudinal edges of the strips 18 are held under tension in relation to their central zones in that the hemstitch 48 intended for the insertion of the clamping bars or inserts 40 is made convex, so that the edge zones in the extended, tensioned state are somewhat shorter than the central zones. However, the strips 18 can also be stabilized transversely to the rolling or tensioning direction. This can e.g. by transverse reinforcing inserts or by the use of non-stretching textile material, for example glass fiber fabric, whereby the shrinkage of the strips in the transverse direction - with tensile stress in the longitudinal direction - can be prevented or at least kept small. Very rigid transverse threads can also be used in relation to the longitudinal threads in order to improve the transverse stability.

Die Längsränder können zugfest verstärkt oder elastischer als die Mittelzone ausgebildet werden. Die Verstärkung der Längsränder kann durch die Ausbildung von Säumen, eine dickere Webkante, das Aufbringen von zugfesten Randbändern oder dergleichen geschehen, was aber den Nachteil hat, dass der Bespannungswickel beim Aufrollen durch die dickeren Randzonen festgelegt ist und die Mittelzonen durchhängen. Dies kann im Lauf der Zeit wiederum zu Verzugserscheinungen führen. Zweckmässig wird eine Verstärkung der Längsränder ohne Dickenzuwachs dadurch erzielt, dass die Randnaht mit leichter Vorspannung (z.B. Kräuselkrepp mit elastischem Faden) eventuell im Zick-Zack genäht wird; oder es werden bereits bei der Herstellung der Stoffstreifen die Randkettfäden aus mehr oder weniger elastischem Material gewählt.The longitudinal edges can be reinforced with tensile strength or more elastic than the central zone. The reinforcement of the longitudinal edges can be achieved by the formation of hems thicker selvedge, the application of tensile edge bands or the like, but this has the disadvantage that the covering roll is fixed when rolling up through the thicker edge zones and the middle zones sag. Again, this can lead to delays. It is useful to reinforce the longitudinal edges without increasing the thickness by sewing the edge seam with a slight pretension (eg crimp crepe with elastic thread) in a zigzag; or the edge warp threads are selected from more or less elastic material during the manufacture of the fabric strips.

Mit Hilfe des gemäss Fig.3 gezeigten Prinzips ist auch eine Doppelmarkise nach Fig.5 möglich,wie sie als Ständermarkise, zur Abdeckung von Glashäusern oder dergleichen zum Einsatz kommt. Die beiden Bespannungen bilden Streifen 418,518 und werden auf einer Tuchwelle 113 auf- bzw. abgerollt. Ihr anderes Ende ist an je einem Ausfallprofil 516 und 516' befestigt.With the aid of the principle shown in FIG. 3, a double awning according to FIG. 5 is also possible, such as that used as a stand awning, for covering glass houses or the like. The two coverings form strips 418, 518 and are rolled up or rolled off on a cloth shaft 113. Its other end is attached to a drop profile 516 and 516 '.

Die Streifen 418 können alternativ auch über eine Umlenkrolle 44 über eine Ebene 418" geführt werden, die dann dieselbe Neigung wie diejenige der Streifen 518 haben kann.The strips 418 can alternatively also be guided over a deflection roller 44 over a plane 418 ″, which can then have the same inclination as that of the strips 518.

Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt. So kann die Tuchwelle beispielsweise mit vier Nuten versehen sein, um die Ausbildung nach Fig. 4a mit derjenigen nach Fig.5 zu kombinieren.The invention is not based on the illustrated embodiment shape limited. For example, the fabric shaft can be provided with four grooves in order to combine the design according to FIG. 4a with that according to FIG.

Ein weiterer Vorteil des Lamellenkonzepts liegt aber auch darin, dass sowohl beim Nähen als auch beim Liefern der zusammengefalteten Markisenstoffe gewisse Verwerfungen oder Faltenbildungen meist nur sehr schwer zu vermeiden sind. Lamellen müssen aber in der Längsrichtung nicht unbedingt genäht werden, sondern werden gerollt geliefert. Damit hat man zwei Probleme mit einem Schlag gelost. Auch bei sehr breiten Markisen wird zur Vermeidung des Durchhängens bisher eine Tuchwellenstütze eingebaut, die zur Folge hat, dass Staub und Schmutz in den Stoff eingerieben werden und dass es Schleifspuren gibt, die nicht mehr zu beseitigen sind, so dass die gesamte Bespannung ausgewechselt werden muss. Bei der streifenförmigen Bespannung kann einfach ein beschädigter oder beschmutzter Streifen problemlos ausgewechselt werden.Another advantage of the slat concept is that certain warps or folds are usually very difficult to avoid both when sewing and when delivering the folded awning fabrics. Slats do not necessarily have to be sewn lengthways, but are delivered rolled. This solved two problems in one fell swoop. Even in the case of very wide awnings, a fabric shaft support has been installed to prevent sagging, which means that dust and dirt are rubbed into the fabric and that there are traces of grinding that can no longer be removed, so that the entire covering must be replaced . With the striped covering, a damaged or soiled strip can easily be replaced.

Bei dem Beispiel nach Fig.8 befinden sich in der hier längs geschlitzten hohlen Tuchwelle 213 in einem der Breite der Streifen 18 entsprechenden axialen Abstand Schnekkengetriebe 47, mit denen die Streifenenden jeweils mittig in Art-einer Jalousie mit lotrechten Lamellen verbunden sind. In der in Fig.8 gezeigten, geschlossenen Lage liegen die Streifen 18 in einer durch die Tuchwellenachse gehenden Ebene. In der in Fig.9 gezeigten Position sind die Streifen 18 gegenüber der Tuchwelle 213 mit Hilfe der Schneckengetriebe 47 um 90 Grad verdreht worden, so dass zum Beispiel Wind in Richtung parallel zur Zeichenebene durchstreichen kann. In Fig.10 schliesslich ist gezeigt, wie die Streifen 18, die andernends am Ausfallprofil 16 befestigt sind, auf die die Schneckengetriebe 47 enthaltende Tuchwelle 213 aufgerollt werden können. Die Betätigung der Schneckengetriebe erfolgt in allgemein bekannter Weise.In the example according to FIG. 8 there are worm gears 47 in the longitudinally slotted hollow cloth shaft 213 at an axial distance corresponding to the width of the strips 18, with which the strip ends are connected in the middle in the manner of a blind with vertical slats. In the closed position shown in FIG. 8, the strips 18 lie in a direction through the fabric shaft axis the level. In the position shown in FIG. 9, the strips 18 have been rotated by 90 degrees with respect to the cloth shaft 213 with the help of the worm gear 47, so that, for example, wind can strike through in the direction parallel to the plane of the drawing. Finally, FIG. 10 shows how the strips 18, which are attached to the drop profile 16 at the other end, can be rolled onto the cloth shaft 213 containing the worm gear 47. The worm gear is actuated in a generally known manner.
