Description

Die Erfindung betrifft eine sonnen- und/oder Wetterschutzvorrichtung, insbesondere für Gebäudeöffnungen, Plätze und dergleichen, mit gegenüber der Vertikalen geneigter bzw. horizontaler Fläche, mit mindestens einem auf einer im Bereich einer Flächenkante der abzuschirmenden Fläche angeordneten Wickelwelle aufnehmbaren, im abgewickelten Zustand vorzugsweise gegenüber der Vertikalen geneigt bzw. horizontal gehaltenen Abdeckvorhang, der durch an seinem dem wickelwellenseitig festgelegten Ende gegenüberliegenden Ende angreifende, mittels einer im Bereich der der Wickelwelle gegenüberliegenden Flächenkante der abzuschirmenden Fläche angeordneten Umlenkeinrichtung umlenkbare Zugorgane betätigbar ist und mittels einer Feder auf Vorspannung gehalten wird.The invention relates to a sun and / or weather protection device, in particular for building openings, squares and the like, with an inclined or horizontal surface with respect to the vertical, with at least one winding shaft arranged in the region of a surface edge of the surface to be shielded, preferably opposite in the developed state the vertical inclined or horizontally held cover curtain, which can be actuated by means of a deflecting device arranged in the area of the surface edge of the surface to be shielded opposite the winding shaft, which can be deflected by its end opposite the end fixed at the end of the winding shaft, and is held by means of a spring to pretension.

Eine Anordnung dieser Art ist aus der DE-A-2 802 078 bekannt. Bei dieser bekannten Anordnung ist das an dem dem wickelwellenseitig festgelegten Ende des Abdeckvorhangs gegenüberliegenden Ende angreifende, mittels einer im Bereich der der Wickelwelle gegenüberliegenden Flächenkante der abzuschirmenden Fläche angeordneten Umlenkeinrichtung umlenkbare Zugorgan nicht an einer mit der Wickelwelle gekuppelten Aufwickeleinrichtung festlegbar. Hierbei ist es daher nicht möglich, mit Hilfe dieses Zugorgans den Abdeckvorhang nicht nur von der zugeordneten Wickelwelle abzuwickeln, sondern auch auf diese aufzuwickeln. Dementsprechend sind bei der Anordnung gemäß DE-A-2 802 078 auch zwei voneinander unabhängige Zugorgane vorgesehen, von denen das eine zum Abwickeln und das andere zum Aufwickeln des Abdeckvorhangs dient. Das zum Aufwickeln des Abdeckvorhangs auf die zugeordnete Wickelwelle dienende Zugorgan ist hierbei an einer zugeordneten Aufwickeltrommel befestigt.An arrangement of this type is known from DE-A-2 802 078. In this known arrangement, the pulling element which engages at the end of the covering curtain fixed on the end of the cover curtain, which can be deflected by means of a deflecting device in the area of the surface edge of the surface to be shielded, cannot be fixed on a winding device coupled to the winding shaft. It is therefore not possible here not only to unwind the covering curtain from the associated winding shaft, but also to wind it up on this with the aid of this pulling element. Accordingly, in the arrangement according to DE-A-2 802 078 two mutually independent pulling elements are provided, one of which is used for unwinding and the other for winding up the covering curtain. The pulling element used to wind up the covering curtain on the associated winding shaft is in this case attached to an assigned winding drum.

Diese ist jedoch fest mit der dem Abdeckvorhang zugeordneten Wickelwelle verbunden. Die der Wickelwelle zugeordnete Feder greift mit ihrem dem an der Welle angreifenden Ende gegenüberliegenden Ende an einer stationären Achse an und dient daher ausschließlich dazu, den Abdeckvorhang im ganz oder teilweise abgewickelten Zustand zu straffen. Der Federweg dieser Feder entspricht dabei der maximalen Abwickelstrecke, wodurch sich konstruktive Beschränkungen ergeben können, welche das Einsatzfeld bekannter Anordnungen gattungsgemäßer Art sehr einschränken. Besonders nachteilig dabei ist jedoch, daß die Federspannung sich in Abhängigkeit vom Federweg ändert. Im abgewickelten Zustand des Abdeckvorhangs greift daher an diesem eine sehr große Kraft an, die praktisch vom Vorhang übertragen werden muß, der hierdurch einer nicht unbeträchtlichen Beanspruchung unterworfen wird, was ebenfalls zu konstruktiven Beschränkungen führen kann. Es erweist sich daher bei den bekannten Anordnungen vielfach als erforderlich, Federn mit einem großen Federweg zu verwenden. Hierdurch ergibt sich jedoch nicht nur ein verhältnismäßig großer baulicher Aufwand, sondern vielfach auch ein sehr großer Platzbedarf. Als ganz besonders nachteilig wird es in diesem Zusammenhang ferner empfunden, daß bei den bekannten Anordnungen die Federgröße praktisch an die jeweils gewünschte Auszugslänge des Abdeckvorhangs angepaßt werden muß, was einer Bauteilstandardisierung völlig entgegenläuft und daher eine rationelle Herstellung praktisch nicht zuläßt.However, this is firmly connected to the winding shaft assigned to the covering curtain. The spring associated with the winding shaft engages with its end opposite the end engaging the shaft on a stationary axis and therefore serves only to tighten the covering curtain in the fully or partially unwound state. The spring travel of this spring corresponds to the maximum unwinding distance, which can result in design restrictions which greatly restrict the field of use of known arrangements of the generic type. However, it is particularly disadvantageous that the spring tension changes as a function of the spring travel. In the unwound state of the covering curtain, therefore, a very large force acts on it, which practically has to be transmitted from the curtain, which is thereby subjected to a not inconsiderable stress, which can also lead to design restrictions. It is therefore often necessary in the known arrangements to use springs with a large spring travel. However, this not only results in a comparatively large structural effort, but in many cases also requires a very large amount of space. In this context, it is also found to be particularly disadvantageous that, in the known arrangements, the spring size has to be adapted practically to the desired extension length of the covering curtain, which is completely contrary to component standardization and therefore practically does not permit rational production.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, unter Vermeidung der Nachteile der bekannten Anordnungen eine Vorrichtung gattungsgemäßer Art zu schaffen, die einfach aufgebaut und kostengünstig herstellbar ist und bei der die zum Auf- bzw. Abwikkeln des Abdeckvorhangs aufzubringende Kraft über der gesamten Auszugsstrecke innerhalb einer engen Bandbreite nahezu konstant bleibt.Proceeding from this, it is therefore the object of the present invention, while avoiding the disadvantages of the known arrangements, to provide a device of the generic type which is simple in construction and inexpensive to manufacture and in which the force to be applied to unwind or unwind the covering curtain over the entire extension path remains almost constant within a narrow range.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zugorgane mit ihrem dem am Abdeckvorhang angreifenden Ende gegenüberliegenden Ende an einer Aufwickeleinrichtung festlegbar sind, die mittels einer Betätigungseinrichtung in Auf- und Abwickelrichtung betätigbar ist und die gegenüber der Wickelwelle verdrehbar gelagert und mittels mindestens einer vorgespannten Feder hiermit antriebsmäßig gekuppelt ist.This object is achieved according to the invention in that the traction elements, with their end opposite the end engaging the covering curtain, can be fixed to a winding device which can be actuated in the winding and unwinding direction by means of an actuating device and which is rotatably mounted with respect to the winding shaft and by means of at least one preloaded spring is coupled in terms of drive.

Die Wickelwelle wird dabei von der den Zugorganen zugeordneten Aufwickeleinrichtung praktisch im Verhältnis 1 : 1 mitgenommen. Infolge der somit gleichförmigen Betätigung von Aufwickeleinrichtung und Wickelwelle bleibt die Spannung der zwischengeordneten Kupplungsfeder in vorteilhafter Weise unabhängig vom zurückgelegten Drehwinkel und damit unabhängig vom Aufzug des Abdeckvorhangs. Die auf den Abdeckvorhang übertragene Spannung bleibt daher in vorteilhafter Weise auf niedrigem Niveau praktisch konstant, was einen schonenden Betrieb und damit eine lange Lebensdauer gewährleistet. Dennoch ist jedoch mittels der federnden Kupplung zwischen Aufwickeleinrichtung und Wickelwelle ein Ausgleich von Wegdifferenzen möglich, die sich dadurch ergeben, daß der Abdeckvorhang und die hieran angreifenden Zugorange praktisch gegenläufig auf die zugeordnete Wickelwelle bzw. die zugeordnete Aufwickeleinrichtung auf- bzw. hiervon abgewickelt werden, so daß der jeweilige Wickeldurchmesser gegenläufig zu- bzw. abnimmt. Die Bandbreite, innerhalb welcher die Federspannung schwankt, läßt sich dabei jedoch in vorteilhafter Weise sehr begrenzen. Die positive Folge davon ist, daß hierbei eine vergleichsweise kleine Feder verwendet werden kann, was eine kompakte Bauweise ermöglicht. Ein weiterer Vorteil iat darin zu sehen, daß hierbei ein und dieselbe Feder praktisch für sämtliche Baugrößen verwendet werden kann. Eine Anpassung der Federgröße und dementsprechend auch der Dimensionierung der die Federkräfte übertragenen Teile an die Verhältnisse des Einzelfalls ist hierbei in vorteilhafter Weise nicht mehr erforderlich, was eine starke Bauteilstandardisierung und damit eine rationelle Herstellung und Lagerhaltung ermöglicht. Die mit der Erfindung erzielbaren Vorteile sind demnach insbesondere in einer ausgezeichneten Wirtschaftlichkeit zu sehen.The winding shaft is taken along practically in a ratio of 1: 1 by the winding device assigned to the pulling elements. As a result of the uniform actuation of the winding device and the winding shaft, the tension of the intermediate coupling spring advantageously remains independent of the angle of rotation traveled and thus independent of the lift of the covering curtain. The voltage transferred to the covering curtain therefore advantageously remains practically constant at a low level, which ensures gentle operation and thus a long service life. Nevertheless, by means of the resilient coupling between the take-up device and the take-up shaft, it is possible to compensate for path differences which result from the fact that the covering curtain and the pulling orange acting thereon are wound up or unwound practically in opposite directions onto the assigned take-up shaft or the take-up device, so that the respective winding diameter increases or decreases in opposite directions. However, the bandwidth within which the spring tension fluctuates can be very limited in an advantageous manner. The positive consequence of this is that a comparatively small spring can be used, which enables a compact design. Another advantage is that one and the same spring can be used for practically all sizes. An adjustment of the spring size and accordingly the Di Dimensioning of the parts transmitted to the spring forces to the circumstances of the individual case is advantageously no longer required, which enables strong component standardization and thus rational production and storage. The advantages that can be achieved with the invention can therefore be seen in particular in excellent economy.

In vorteilhafter Weise können die Wickelwelle und die den Zugorganen zugeordnete Aufwickeleinrichtung koaxial zueinander angeordnet sein. Hierdurch läßt sich eine besonders platzsparende und kompakte Ausführung erreichen. In weiterer Fortbildung dieses Gedankens kann dabei die den Zugorganen zugeordnete Aufwickeleinrichtung mit einer die Wickelwelle durchsetzenden, federnd hiermit gekuppelten Treibwelle versehen sein, auf der den Zugorganen zugeordnete, seitlich neben der Wickelwelle angeordnete Aufwickelorgane befestigt sind. Die Wickelwelle kann dabei in vorteilhafter Weise auf der Treibwelle gelagert sein, wodurch nicht nur der bauliche Aufwand und der Platzbedarf gesenkt werden können, sondern gleichzeitig auch eine werkstattseitige Vormontage und damit eine einfache bauseitige Montage dieser gesamten Baueinheit ermöglicht werden.The winding shaft and the winding device assigned to the traction elements can advantageously be arranged coaxially to one another. This enables a particularly space-saving and compact design to be achieved. In a further development of this idea, the take-up device assigned to the pulling elements can be provided with a drive shaft which passes through the winding shaft and is coupled to it in a spring-like manner, on which take-up elements which are assigned to the pulling elements and are arranged laterally next to the winding shaft are fastened. The winding shaft can be mounted on the drive shaft in an advantageous manner, which not only reduces the structural outlay and the space required, but also enables a pre-assembly on the workshop side and thus a simple on-site assembly of this entire assembly.

Eine besonders einfache Ausgestaltung der übergeordneten Maßnahmen kann darin bestehen, daß die die Treibwelle mit der Wickelwelle federnd kuppelnde Feder als die Treibwelle umgreifende Spiralfeder ausgebildet ist. Hierbei handelt es sich um ein vergleichsweise billiges und dennoch sehr robustes Bauteil.A particularly simple embodiment of the superordinate measures can consist in the spring coupling the drive shaft with the winding shaft being designed as a spiral spring encompassing the drive shaft. This is a comparatively cheap, yet very robust component.

In weiterer Fortbildung der übergeordneten Maßnahmen können die der Wickelwelle zugeordnete. und die der Umlenkeinrichtung zugeordnete Baueinheit jeweils in einem mit einem Auslaßschlitz für den Abdeckvorhang bzw. für die Zugorgane versehenen Kasten angeordnet sein. Hierdurch ergibt sich nicht nur eine geschützte Unterbringung dieser Baueinheiten, sondern gleichzeitig auch ein sauberes Aussehen.In a further development of the higher-level measures, those associated with the winding shaft can be. and the structural unit assigned to the deflection device can each be arranged in a box provided with an outlet slot for the covering curtain or for the traction elements. This not only results in the protected accommodation of these units, but also a clean appearance.

Die erfindungsgemäßen Maßnahmen können bei einer mit einem Markisentuch ausgestatteten Verschattung Anwendung finden. Zweckmäßig kann dabei das dem an der Wickelwelle befestigten Ende gegenüberliegende Ende des Markisentuchs an einer über die gesamte Bahnbreite sich erstreckenden Zugschiene befestigt sein, an der die Zugorgane angreifen. Hierdurch ist eine gleichmäßige Spannung des Markisentuchs gewährleistet.The measures according to the invention can be used in the case of shading equipped with an awning fabric. The end of the awning fabric opposite the end fastened to the winding shaft can expediently be fastened to a pulling rail which extends over the entire width of the web and on which the pulling elements act. This ensures an even tension of the awning fabric.

Die erfindungsgemäßen Maßnahmen können aber auch bei einer mit einem Lamellenpanzer ausgestatteten Vorrichtung, etwa einem Rolladen, einem Rolltor oder einer Rollabdeckung oder dergleichen Verwendung finden. In diesem Fall kann die in Abwickelrichtung vordere Lamelle zweckmäßig als Zugschiene ausgebildet sein, an der die Zugorgane angreifen.However, the measures according to the invention can also be used in a device equipped with a slatted armor, for example a roller shutter, a roller shutter or a roller cover or the like. In this case, the front lamella in the unwinding direction can expediently be designed as a pulling rail on which the pulling elements act.

Zur Führung der Zugschiene und gegebenenfalls sämtlicher Lamellen eines Lamellenpanzers können zwischen der Wickelwelle und der Umlenkeinrichtung angeordnete Führungsschienen vorgesehen sein. Hierdurch ergibt sich in vorteilhafter Weise eine genaue Höhenfixierung der Zugschiene, wodurch die Zugorgane entlastet werden. Gleichzeitig eignen sich diese Führungsschienen in vorteilhafter Weise für eine schützende Aufnahme des zugeordneten Trums derZugorgane.Guide rails arranged between the winding shaft and the deflection device can be provided for guiding the pull rail and possibly all the slats of a slat armor. This advantageously results in a precise height fixation of the pull rail, which relieves the tension on the tension members. At the same time, these guide rails are advantageously suitable for protecting the associated run of the traction members.

Weitere vorteilhafte Ausgestaltungen und bevorzugte Weiterbildungen der übergeordneten Maßnahmen ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung in Verbindung mit den restlichen Unteransprüchen.Further advantageous refinements and preferred developments of the superordinate measures result from the following description of an exemplary embodiment with reference to the drawing in conjunction with the remaining subclaims.

Die den Fig. zugrunde liegende erfindungsgemäße Pergolaverschattung findet in erster Linie als Sonnenschutz für den darunter sich befindenden Laubengang Verwendung. Hierzu ist ein einen nahezu waagrechten Abdeckvorhang 1 bildendes, bahnförmiges Markisentuch vorgesehen, das in Form eines im Bereich einer Flächenkante des abzuschirmenden Platzes, hier im Bereich der durch die benachbarte Wand 2 gebildeten Flächenkante angeordneten Wickelballens 3 bereit gehalten und bei Bedarf hiervon abwickelbar ist. Am freien, in Abwickelrichtung vorderen Ende des den Abdeckvorhang 1 bildenden Markisentuchs greifen hier durch strichpunktierte Linien angedeutete, vorzugsweise als Gurte ausgebildete Zugorgane 4 an, mittels welcher der Abdeckvorhang 1 vom zugeordneten Wickelballen 3 abziehbar ist. Die Zugorgane 4 werden im Bereich einer an der der Wand 2 gegenüberliegenden Flächenkante der abzuschirmenden Fläche angeordneten Umlenkeinrichtung 5 gegenüber der durch den Pfeil 6 verdeutlichten Auszugsrichtung des Abdeckvorhangs 1 umgelenkt. Die Umlenkeinrichtung 5 ist hier einfach mit den einzelnen, die Zugorgane 4 bildenden Gurten zugeordneten, frei drehbar gelagerten Umlenkrollen 7 versehen. Das beim Abwikkein des Abdeckvorhangs 1 vom Wickelballen 2 in Bewegungsrichtung vordere, also dem am Abdeckvorhang 1 angreifenden Ende gegenüberliegende Ende der Zugorgane 4 ist an einer zugeordneten Aufwickeleinrichtung 8 befestigt. Die Auf- und Abwickelrichtungen von Abdeckvorhang 1 und Zugorganen 3 sind gegenläufig, so daß beim Abwickeln des Abdeckvorhangs 1 vom Wickelballen 3 die Zugorgane 4 gleichzeitig auf die zugeordnete Aufwickeleinrichtung 8 aufgewickelt werden und umgekehrt. Im dargestellten Ausführungsbeispiel mit koaxialer Anordnung und gleichsinniger Drehung von Wickelballen 3 und Aufwickeleinrichtung 8 wird dies einfach dadurch bewerkstelligt, daß der Abdeckvorhang 1 im Bereich der oberen Kante des Wikkelballens 3 und die Zugorgane 4 im Bereich der unteren Kante der jeweils zugeordneten Aufwikkeleinrichtung 8, also praktisch diametral einander gegenüberliegend, auf- bzw. abgewickelt werden.The pergola shade according to the invention, which is the basis for the figures, is primarily used as sun protection for the arcade below. For this purpose, an almost horizontal covering curtain 1 is provided, which is provided in the form of a wrapping bale 3 arranged in the area of a surface edge of the space to be shielded, here in the region of the surface edge formed by the adjacent wall 2, and can be unwound from it if necessary. At the free end of the awning fabric forming the covering curtain 1 in the unwinding direction, tension elements 4, preferably designed as straps, are indicated by dash-dotted lines, by means of which the covering curtain 1 can be pulled off the associated wrapping roll 3. The traction elements 4 are deflected in the region of a deflecting device 5 arranged on the surface edge of the surface to be shielded, opposite the direction of extension of the covering curtain 1 illustrated by the arrow 6. The deflection device 5 is here simply provided with the individual, freely rotatably mounted deflection rollers 7 associated with the straps 4 forming belts. The end of the traction elements 4 which is at the front in the direction of movement when the covering curtain 1 is removed from the wrapping roll 2, that is to say opposite the end which engages on the covering curtain 1, is fastened to an associated winding device 8. The winding and unwinding directions of the covering curtain 1 and pulling elements 3 are in opposite directions, so that when the covering curtain 1 is unwound from the winding bale 3, the pulling elements 4 are simultaneously wound onto the associated winding device 8 and vice versa. In the picture Th embodiment with coaxial arrangement and rotation of the winding bale 3 and winding device 8 in the same direction is accomplished simply by the fact that the covering curtain 1 in the area of the upper edge of the winding bale 3 and the traction elements 4 in the area of the lower edge of the respectively associated winding device 8, that is to say practically diametrically opposite, wound up or unwound.

Zur Aufnahme des Abdeckvorhangs 1 bzw. des zugeordneten Wickelballens 3 ist, wie Fig. 2 am besten erkennen läßt, eine rohrförmige Wikkelwelle 9 vorgesehen, die sich über die gesamte Breite der hier den Abdeckvorhang 1 bildenden Tuchbahn erstreckt.As can best be seen in FIG. 2, a tubular winding shaft 9 is provided for receiving the covering curtain 1 or the associated wrapping bale 3, which extends over the entire width of the sheet of material forming the covering curtain 1 here.

Die den hier im Bereich der äußeren Ecken der in Abwickelrichtung vorderen Kante des Abdeckvorhangs 1 angreifenden Zugorganen 4 zugeordnete Aufwickeleinrichtung 8 besteht, wie Fig. 2 weiter erkennen läßt, aus seitlich neben der Wickelwelle 9 angeordneten Gurtscheiben 10, die auf einer die Wickelwelle 9 koaxial durchsetzenden Treibwelle 11 durch Stifte 12 drehfest befestigt sind. Die Treibwelle 11 ist mittels einer zugeordneten Antriebseinrichtung 13 antreibbar. Diese besteht im dargestellten Ausführungsbeispiel aus einem mit einer abnehmbaren Kurbel in Eingriff bringbaren Antriebszapfen. Zur Bewerkstelligung der gewünschten Untersetzung ist ein in einem Kasten untergebrachtes Vorgelege 14 vorgesehen, dessen Eingang durch den Antriebszapfen 13 gebildet wird und dessen Ausgang mit der Treibwelle 11 verbunden ist. Es wäre aber auch ohne weiteres denkbar, anstelle eines Handantriebs zum Antrieb der Treibwelle 11 einen Motor vorzusehen. Dieser könnte in platzsparender Weise direkt in der zweckmäßig ebenfalls durch ein Rohr gebildeten Treibwelle 11 untergebracht werden, wie in Fig. 2 durch strichpunktierte Linien bei 15 angedeutet ist.The winding device 8 assigned here in the region of the outer corners of the front edge of the covering curtain 1 attacking in the unwinding direction consists, as can also be seen in FIG. 2, of belt pulleys 10 arranged laterally next to the winding shaft 9 and coaxially penetrating the winding shaft 9 on one Drive shaft 11 are rotatably attached by pins 12. The drive shaft 11 can be driven by means of an associated drive device 13. In the exemplary embodiment shown, this consists of a drive pin which can be brought into engagement with a removable crank. To achieve the desired reduction, a countershaft 14 is provided, the input of which is formed by the drive pin 13 and the output of which is connected to the drive shaft 11. However, it would also be readily conceivable to provide a motor instead of a manual drive for driving the drive shaft 11. This could be accommodated in a space-saving manner directly in the drive shaft 11, which is likewise expediently formed by a tube, as is indicated in FIG. 2 by dash-dotted lines at 15.

Die Wickelwelle 9 ist durch seitliche Stützringe 16 frei drehbar auf der Treibwelle 11 aufgenommen und ist von dieser über eine vorgespannte Feder 17 gleichsinnig und gleichförmig antreibbar. Die Feder 17 ist im dargestellten Ausführungsbeispiel als die Treibwelle 11 umfassende, im Ringraum zwischen Treibwelle 11 und Wickelwelle 9 angeordnete Spiralfeder ausgebildet, die mit einem Ende an einem treibwellenseitig festgelegten Mitnehmerring 18 und mit ihrem anderen Ende an einem wickelwellenseitig festgelegten, hier durch den benachbarten Stützring 16 gebildeten Mitnehmerring befestigt ist. Die durch die Feder 17 bewerkstelligte federnde Kupplung zwischen der mittels einer Antriebseinrichtung antreibbaren Treibwelle 11 und der Wickelwelle 9 stellt sicher, daß diese zusammen mit der Treibwelle 9 hier gleichförmig und gleichsinnig angetrieben wird, womit der Abdeckvorhang 1 und die Zugorgane 4 infolge ihres diametral versetzten Auflaufs gemäß Fig. 1 gegenläufig auf- bzw. abwickelbar sind. Durch die Feder 17 werden gleichzeitig die infolge der gegenläufigen Durchmesservergrößerung bzw. -verkleinerung im Bereich des Wickelballens 3 und der auf den Gurtscheiben 10 aufgenommenen Wicklungen sich ergebenden Wegdifferenzen ausgeglichen. Die Federspannung schwankt dabei innerhalb einer schmalen Bandbreite um einen eingestellten Ausgangswert.The winding shaft 9 is freely rotatably received on the drive shaft 11 by lateral support rings 16 and can be driven by the latter via a prestressed spring 17 in the same direction and uniformly. In the illustrated embodiment, the spring 17 is designed as a spiral spring comprising the drive shaft 11 and arranged in the annular space between the drive shaft 11 and the winding shaft 9, which has one end on a drive ring 18 fixed on the drive shaft side and the other end on a drive shaft fixed on the winding shaft side, here by the adjacent support ring 16 formed driving ring is attached. The springy coupling accomplished by the spring 17 between the drive shaft 11, which can be driven by a drive device, and the winding shaft 9 ensures that it is driven here together with the drive shaft 9 uniformly and in the same direction, with which the covering curtain 1 and the traction elements 4, as a result of their diametrically offset casserole 1 can be wound up or unwound in opposite directions. By means of the spring 17, the path differences resulting as a result of the opposite diameter enlargement or reduction in the area of the winding bale 3 and the windings recorded on the belt disks 10 are simultaneously compensated. The spring tension fluctuates within a narrow range around a set output value.

Die im Bereich der Feder 17 eingestellte Vorspannung ist so gewählt, daß der Abdeckvorhang 1 im abgewickelten Zustand einerseits straff gespannt ist, andererseits jedoch nicht überbeansprucht wird. Die Feder 17 ist dabei so auszulegen, daß der hierbei zur Verfügung stehende Federweg jedenfalls zum Ausgleich der vorstehend angesprochenen Wegdifferenzen ausreicht. Die Vorspannung der Feder 17 kann dadurch bewerkstelligt werden, daß ausgehend von einer entspannten Stellung die frei drehbar gelagerte Wickelwelle 9 bei stehender Treibwelle 11 um einen entsprechenden Winkel verdreht wird, und daß anschließend erst eine straffe Verbindung des in Auszugsrichtung vorderen Endes des Abdeckvorhangs 1 mit den Zugorganen 4 hergestellt wird. Dies kann bauseits während der Montagearbeiten erfolgen. Es wäre aber auch denkbar, die Feder 17 bereits werksseitig vorzuspannen. In diesem Falle müßten die durch die vorgespannte Feder 17 miteinander gekuppelten Wellen 9 und 11 zunächst etwa mittels eines Sitfts oder dergleichen gegen gegenseitiges Verdrehen gesichert sein. Die Entsicherung würde dabei nach erfolgter Verbindung des Abdeckvorhangs 1 mit den zugeordneten Zugorganen 4 erfolgen.The preload set in the area of the spring 17 is selected such that the covering curtain 1 is taut on the one hand in the unwound state, but on the other hand is not overstressed. The spring 17 is to be designed in such a way that the available spring travel is sufficient to compensate for the travel differences mentioned above. The pretensioning of the spring 17 can be accomplished in that, starting from a relaxed position, the freely rotatably mounted winding shaft 9 is rotated by a corresponding angle when the drive shaft 11 is at a standstill, and then only a tight connection of the front end of the covering curtain 1 in the pull-out direction with the Traction elements 4 is produced. This can be done on site during assembly work. However, it would also be conceivable to preload the spring 17 at the factory. In this case, the shafts 9 and 11, which are coupled to one another by the prestressed spring 17, would first have to be secured against mutual rotation by means of a shaft or the like. Unlocking would take place after the covering curtain 1 had been connected to the associated pulling elements 4.

Der hier durch ein bahnförmig geschnittenes Markisentuch gebildete Abdeckvorhang 1 ist mit seinem in Abwickelrichtung vorderen Ende an einer über die gesamte Bahnbreite sich erstrekkenden Spannschiene 19 festgelegt, die die von den Zugorganen 4 ausgeübten Kräfte gleichmäßig auf die gesamte Vorderkante des Abdeckvorhangs 1 übertragen. Die Spannschiene 19 kann mit dem zugeordneten Ende des Abdeckvorhangs 1 verstiftet sein. Bei dem in Fig. 3 dargestellten Ausführungsbeispiel ist das hier den Abdeckvorhang 1 bildende Markisentuch mit einem Hohlsaum 20 versehen, in den die hier zur Vermeidung von scharfen Kanten zweckmäßig als Rohr ausgebildete Spannschiene 19 eingelegt ist. Die Spannschiene 19 ist im Bereich ihrer Enden mit die betreffenden Seitenkanten des Abdeckvorhangs 1 überragenden Führungslaschen 21 versehen, die, wie am besten aus Fig. 4 erkennbar ist, in einen jeweils zugeordneten Führungskanal von seitlichen Spannschienen 22 eingreifen, die, wie Fig. 1 zeigt, die die Umlenkeinrichtung 5 aufnehmende Baueinheit und die den Wickelballen 3 und die Aufwickeleinrichtung 8 aufnehmende Baueinheit miteinander verbinden.The cover curtain 1 formed here by a web-shaped awning fabric is fixed with its front end in the unwinding direction to a tensioning rail 19 which extends over the entire width of the web and which uniformly transmit the forces exerted by the pulling elements 4 to the entire front edge of the cover curtain 1. The tensioning rail 19 can be pinned to the associated end of the covering curtain 1. In the embodiment shown in FIG. 3, the awning fabric forming the covering curtain 1 is provided with a hemstitch 20, in which the tensioning rail 19, which is expediently designed as a tube to avoid sharp edges, is inserted. The tensioning rail 19 is provided in the region of its ends with guide tabs 21 which project beyond the relevant side edges of the covering curtain 1 and which, as can best be seen from FIG. 4, engage in a respectively assigned guide channel of lateral tensioning rails 22 which, as shown in FIG. 1 which connect the structural unit receiving the deflection device 5 and the structural unit receiving the bale 3 and the winding device 8.

Die Führungslaschen 21 können direkt an die Spannschiene 19 angeformt sein. Im dargestellten Ausführungsbeispiel ist die rohrförmige Spannschiene 19 mit seitlichen, die Führungslaschen 21 aufweisenden, vorzugsweise als Kunststoff-Formlinge ausgebildeten Steckzapfen versehen. Die zur Bildung der Zugorgane 4 hier vorgesehenen Gurte sind an den den Abdeckvorhang 1 seitlich überragenden Führungslaschen befestigt, wodurch sichergestellt ist, daß die auf den seitlich neben der Wickelwelle 9 angeordneten Gurtscheiben 10 aufnehmbaren Gurte lotrecht zur Achse ihrer Aufwickeleinrichtung verlaufen, wodurch Seitenzug vermieden wird und die Gurtkanten geschont werden. Gleichzeitig ist hierdurch sichergestellt, daß die die Zugorgane 4 bildenden Gurte im Bereich der Führungsschienen 22 in dem den Führungslaschen 21 zugeordneten Laufkanal 23 laufen, was die Gurte im Bereich ihres gefährdeten oberen Trums der direkten Einwirkung der Witterung entzieht. Bei Verwendung eines Lamellenpanzers zur Bildung des Abdeckvorhangs 1, etwa im Falle eines Rollladens, einer Schwimmbadabdeckung und dergleichen, kann einfach die in Abwickelrichtung vorderste Lamelle zur Bildung der Spannschiene verstärkt und gegenüber den übrigen Lamellen etwas verlängert sein. In vorteilhafter Weise können bei einer derartigen Ausführung die Enden sämtlicher Lamellen in seitliche Führungsschienen eingreifen, die das Lamellengewicht aufnehmen und eine exakte Geradführung des Lamellenpanzers gewährleisten.The guide tabs 21 can be molded directly onto the tensioning rail 19. In the exemplary embodiment shown, the tubular tensioning rail 19 is provided with lateral plug pins, which have the guide tabs 21 and are preferably designed as plastic moldings see. The straps provided here to form the traction elements 4 are fastened to the guide tabs projecting laterally from the covering curtain 1, which ensures that the straps 10 which can be accommodated on the belt disks 10 arranged laterally next to the winding shaft 9 run perpendicular to the axis of their winding device, thereby avoiding side pull and the belt edges are protected. At the same time, this ensures that the straps forming the traction elements 4 run in the region of the guide rails 22 in the running channel 23 assigned to the guide plates 21, which removes the straps from the direct influence of the weather in the region of their end strand which is at risk. When using a slat armor to form the cover curtain 1, for example in the case of a roller shutter, a swimming pool cover and the like, the foremost slat in the unwinding direction can simply be reinforced to form the tensioning rail and somewhat lengthened compared to the other slats. In an embodiment of this type, the ends of all the slats can advantageously engage in lateral guide rails which absorb the slat weight and ensure exact straight guidance of the slat armor.

Die hier die Zugorgane 4 bildenden Gurte sind an ihren spannschienenseitigen Enden, wie Fig. 3 zeigt, mit jeweils einer Schlaufe 24 versehen, die in einen spannschienenseitig vorgesehenen Bügel 25 einhängbar ist. Der Bügel 25 ist im dargestellten Ausführungsbeispiel mit einem Gewindestift 26 versehen, der durch eine zugeordnete Bohrung im Bereich der zugeordneten Führungslasche 21 hindurchgreift und mittels einer Mutter 27, die mittels einer Gegenmutter gesichert sein kann, hieran verstellbar abgestützt ist. Hierdurch ist es möglich, Längendifferenzen im Bereich der Zugorgane 4 auszugleichen und damit einen gleichmäßigen Zug sämtlicher Zugorgane 4 zu gewährleisten.The straps forming the tension members 4 here are provided at their ends on the tensioning rail side, as shown in FIG. 3, each with a loop 24 which can be suspended in a bracket 25 provided on the tensioning rail side. The bracket 25 is provided in the illustrated embodiment with a threaded pin 26 which extends through an associated bore in the area of the associated guide plate 21 and is adjustably supported thereon by means of a nut 27, which can be secured by means of a lock nut. This makes it possible to compensate for differences in length in the area of the tension members 4 and thus to ensure a uniform pull of all the tension members 4.

Durch die die Führungslaschen 21 aufnehmenden Führungsschienen 22 wird im dargestellten Ausführungsbeispiel, wie Fig. 1 am besten erkennen läßt, der Abstand zwischen der dem Wickelballen 3 zugeordneten Baueinheit und der die Umlenkeinrichtung 5 enthaltenden Baueinheit überbrückt. Im dargestellten Ausführungsbeispiel ist die den dem Abdeckvorhang 1 zugeordneten Wickel 3 und die den Gurten 4 zugeordnete Aufwickeleinrichtung 8 enthaltende Baueinheit in einem als Ganzes mit 28 bezeichneten Kasten untergebracht. Dieser kann einfach, wie Fig. 2 am besten erkennen läßt, durch seitliche Lagerschalen 29 zur Lagerung der hier zentral angeordneten Treibwelle 11 und einem diese Lagerschalen miteinander verbindenden, über die gesamte Breite der erfindungsgemäßen Anordnung sich erstreckenden Mantel 30. Dasselbe kann für die die Umlenkeinrichtung 5 aufnehmende Baueinheit gelten. Es wäre aber auch möglich, hier jeder Umlenkrolle 7 einen eigenen Kasten 31 zuzuordnen, der einfach aus einer die Umlenkrolle 7 aufnehmenden Lagerschale und einem hieran festgelegten Deckel bestehen kann. Die Kästen 28 bzw. 31 sind mit Ein- und Auslaßschlitzen für den Abdeckvorhang 1 bzw. die Zugorgane 4 versehen. Die Führungsschienen 22 können einfach an den Kästen 28 und 31 festgelegt sein. Bei dem der Fig. 4 zugrunde liegenden Beispiel sind die Führungsschienen 22 durch zusätzliche Stützen 32 gebäudeseitig abgestützt.1, the distance between the assembly assigned to the wrapping bale 3 and the assembly containing the deflection device 5 is bridged by the guide rails 22 receiving the guide tabs 22 in the illustrated embodiment, as can be seen best in FIG. 1. In the exemplary embodiment shown, the structural unit containing the winding 3 assigned to the covering curtain 1 and the winding device 8 assigned to the belts 4 is accommodated in a box designated 28 as a whole. This can, as can be seen best in FIG. 2, by lateral bearing shells 29 for mounting the drive shaft 11 arranged here centrally and a jacket 30 connecting these bearing shells to one another and extending over the entire width of the arrangement according to the invention. The same can be done for the deflection device 5 receiving unit apply. However, it would also be possible here to assign each deflection roller 7 its own box 31, which can simply consist of a bearing shell receiving the deflection roller 7 and a cover attached to it. The boxes 28 and 31 are provided with inlet and outlet slots for the covering curtain 1 and the traction elements 4. The guide rails 22 can simply be fixed to the boxes 28 and 31. In the example on which FIG. 4 is based, the guide rails 22 are supported on the building side by additional supports 32.

Im Falle einer sehr großen Breite der abzuschirmenden Fläche kann es zur Vermeidung einer Durchbiegung der über die gesamte Breite sich erstreckenden Spannschiene 19 zweckmäßig sein, mehrere gleichmäßig über die Länge der Spannschiene 19 verteilte Zugorgane vorzusehen und den Abdeckvorhang 1 in dementsprechend viele Fehler zu unterteilen. Jedem Vorhangfeld kann dabei eine Wickelwelle zugeordnet sein, wobei sämtliche fluchtend nebeneinander angeordnete Wickelwellen auf einer gemeinsamen Treibwelle aufgenommen sein können. Im Bereich zwischen den einzelnen Wickelwellen können dabei zusätzliche Gurtscheiben oder dergleichen zum Aufwickeln zusätzlicher Zugorgane vorgesehen sein.In the case of a very large width of the surface to be shielded, it may be advisable, in order to avoid deflection of the tensioning rail 19 extending over the entire width, to provide a plurality of tension members distributed uniformly over the length of the tensioning rail 19 and to subdivide the covering curtain 1 accordingly. A winding shaft can be assigned to each curtain field, it being possible for all winding shafts arranged in alignment next to one another to be accommodated on a common drive shaft. In the area between the individual winding shafts, additional belt pulleys or the like can be provided for winding up additional traction elements.
