Description

Die vorliegende Erfindung befasst sich mit einer Sonnen- oder Regenschutzanlage mit einem ausfahrbaren Behang, der in zwei Teilbereiche unterteilt ist, die auf einer gemeinsamen, mittig angeordneten Wickelwelle aufwickelbar sind, wobei die Teilbehänge durch eine Federspannvorrichtung gestrafft sind und ihre freien Enden jeweils mit einer Zugeinrichtung verbunden sind.The present invention relates to a sun or rain protection system with an extendable curtain, which is divided into two sections, which can be wound on a common, centrally arranged winding shaft, the part hangers are tightened by a spring tensioning device and their free ends each with a pulling device are connected.

Eine solche Anlage ist beispielsweise in der EP 0865 557 B1 gezeigt. Dort ist vorgesehen, Wickelrollen für die Zugeinrichtung unmittelbar starr auf der Wickelwelle für ein Sonnensegel anzuordnen, wodurch sich Antriebselemente kompakt im Bereich der Wickelwelle integrieren lassen. Allerdings ist es aufgrund der sich gegenläufig ändernden Wickeldurchmesser von Wickelwelle und Wickelrolle notwendig, einen Federausgleich im Rahmen der Federspannvorrichtung vorzusehen, der bei einer starr auf der Wickelwelle angeordneten Wickelrolle notwendigerweise im Bereich der Zugeinrichtung vorgesehen sein muss, deren Aufbau sich dadurch erheblich verkompliziert.Such a plant is for example in the EP 0865 557 B1 shown. There it is provided to arrange winding rollers for the pulling device directly rigidly on the winding shaft for an awning, which can be compactly integrated drive elements in the winding shaft. However, it is necessary due to the counter-rotating winding diameter of winding shaft and winding roll to provide a spring balance in the context of the spring tensioning device, which necessarily has to be provided in a fixedly arranged on the winding shaft winding roller in the drawbar, the structure is thereby considerably complicated.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Anlage zu schaffen, die eine vereinfachte Zugeinrichtung aufweist.The object of the present invention is to provide a system which has a simplified drawbar.

Erfindungsgemäß wird die Aufgabe durch eine Anlage der eingangs beschriebenen Art gelöst, bei welcher die Zugeinrichtung ein durchgängiges, die freien Enden der Behangteile verbindendes Umlenkseil, das über wenigstens zwei Umlenkrollen umgelenkt ist, und ein Zugseil besitzt, das in verschiedenen Lagen festlegbar, auf einer Wickelrolle aufwickelbar oder aufspulbar ist und das an einer der beiden Umlenkrollen festgelegt ist, die beweglich ist, wobei die Federspannvorrichtung innerhalb der Wickelwelle angeordnet ist und eine Zugkraft in der Einfahrrichtung auf die Teilbereiche des Behangs ausübt.According to the invention the object is achieved by a system of the type described above, in which the pulling device has a continuous, the free ends of the Behangteile connecting Umlenkseil which is deflected over at least two pulleys, and a pull rope, in different Layers can be fixed, wound on a winding roll or wound up and which is fixed to one of the two pulleys, which is movable, wherein the spring tensioning device is disposed within the winding shaft and exerts a tensile force in the retraction direction on the sub-areas of the curtain.

Die erfindungsgemäße Anlage bietet den Vorteil, dass es nicht mehr notwendig ist, den Federausgleichsmechanismus im Bereich der Zugeinrichtung zwischen der Wickelrolle und der Wickelwelle vorzusehen, sondern beispielsweise im Bereich der Wickelwelle oder im Bereich der Wickelrolle, wobei in der Regel ein manueller oder elektrischer Antrieb die Teilbereiche des Behangs ausfährt und die Federspannvorrichtung eine Zugkraft in der Einfahrrichtung auf die Teilbereiche des Behangs ausübt. Die Federspannvorrichtung ist dabei in der Wickelwelle angeordnet, wobei durch die integrierte Anordnung der Federmechanismus zum einen unsichtbar ist und zum anderen auch ein Schutz der zueinander beweglichen Teile vor Verschmutzung gegeben ist, die die Funktion beeinträchtigen könnte.The system according to the invention has the advantage that it is no longer necessary to provide the spring balancing mechanism in the region of the pulling device between the winding roll and the winding shaft, but for example in the field of winding shaft or in the winding roll, usually a manual or electric drive the Extends portions of the curtain and the spring tensioning device exerts a tensile force in the retraction on the sub-areas of the curtain. The spring tensioning device is arranged in the winding shaft, being invisible by the integrated arrangement of the spring mechanism on the one hand and on the other hand, a protection of the mutually moving parts is given against contamination, which could affect the function.

Bedingt durch die doppelte Umlenkung des Umlenkseiles in Verbindung mit dem auf nur eine Umlenkrolle wirkenden Zugseil ergibt sich auch eine Übersetzung nach dem Flaschenzugprinzip, so dass nur eine geringere Zugseillänge aufgewickelt werden muss und die Wickelrolle entsprechend kleiner dimensioniert sein kann.Due to the double deflection of the Umlenkseiles in conjunction with the acting on only one pulley pull rope also results in a translation according to the pulley principle, so that only a smaller Zugseillänge must be wound and the winding roll can be dimensioned correspondingly smaller.

Die Anlage kann als Sonnenschutzanlage einen Tuchbehang, z. B. in der Form eines Sonnensegels aufweisen. Je nach Anwendung können z. B. aber auch Wachstücher, Planen oder starke Kunststofffolien eingesetzt werden, insbesondere wenn die Anlage auch als Regenschutz eingesetzt wird. Vorzugsweise sind zum Erreichen einer besonders einfachen Zugeinrichtung lediglich zwei Umlenkrollen vorgesehen, wobei die zweite Umlenkrolle ortsfest, d. h. unbeweglich gelagert ist. In einem solchen Fall verläuft das Umlenkseil unterhalb des ausfahrbaren Behangs, wobei es bereits mit einer einzigen weiteren Umlenkrolle möglich ist, das Umlenkseil seitlich an der durch den Behang verschattbaren Fläche vorbeizuführen.The plant can be used as a sunscreen a Tuchbehang, z. B. in the form of a sunshade. Depending on the application z. As well as oilcloths, tarpaulins or strong plastic films are used, especially if the Plant is also used as a rain cover. Preferably, to achieve a particularly simple traction device only two pulleys provided, the second pulley stationary, that is immovably mounted. In such a case, the Umlenkseil runs below the retractable curtain, whereby it is already possible with a single further deflection roller to pass the Umlenkseil laterally shaded by the curtain surface.

In einer besonders bevorzugten Ausführungsform der Erfindung sind die Teilbereiche des Behangs dreiecksförmig ausgebildet, wobei die Zugeinrichtung jeweils an dem spitzen freien Ende der Teilbereiche angreift.In a particularly preferred embodiment of the invention, the subregions of the curtain are triangular in shape, wherein the pulling device engages in each case at the pointed free end of the subregions.

Bei einer solchen Ausführungsform ist die Sonnenschutzanlage in der Art eines sog. Sonnensegels ausgebildet, d. h. sie bildet ein freistehendes System, das nicht auf einem Rahmen, wie z. B. auch einem Wintergarten oder einem Glasdach aufgeständert sein muss. Gleichwohl lassen sich die erfindungsgemäßen Erneuerungen auch bei sog. Wintergartenmarkisen vorteilhaft einsetzen, bei denen in der Regel an den freien Tuchenden ein in seitlichen Führungsschienen geführtes Ausfahrprofil vorgesehen ist.In such an embodiment, the sunshade system is designed in the manner of a so-called awning, d. H. it forms a freestanding system that is not on a frame, such. B. also a conservatory or a glass roof must be elevated. Nevertheless, the renewals according to the invention can also be used advantageously in what are known as conservatory awnings, in which, as a rule, an extension profile guided in lateral guide rails is provided at the free cloth ends.

Die bereits angesprochene Anordnung der Federspannvorrichtung zwischen Lagerstellen und der Wickelwelle in einem Hohlrauminne der Wickelwelle stellt eine besonders vorteilhafte Ausführungsform der Erfindung dar.The already-mentioned arrangement of the spring tensioning device between bearing points and the winding shaft in a cavity of the winding shaft winding constitutes a particularly advantageous embodiment of the invention.

Im einfachsten Fall ergibt sich ein frei tragendes Sonnensegel, das zwischen den beiden Lagerstellen der Wickelwelle, der ortsfesten Umlenkrolle und der Wickelrolle für das Zugseil aufgespannt ist. Weitergehende Trag- oder Führungselemente sind nicht erforderlich. Dabei ist die bewegliche Umlenkrolle vorteilhaft auf einer Bahn zwischen der Wickelrolle und der Wickelwelle beweglich, wenn keine weiteren Umlenk- oder Führungselemente vorgesehen sind.In the simplest case, a free-standing sun sails, which is clamped between the two bearing points of the winding shaft, the stationary guide roller and the winding roller for the pull rope results. Further support or guide elements are not required. Here is the moving Guide roller advantageous on a path between the winding roller and the winding shaft movable when no further deflection or guide elements are provided.

Nachfolgend wird anhand der beigefügten Zeichnungen näher auf ein Ausführungsbeispiel der Erfindung eingegangen. Es zeigen:

Hereinafter, an embodiment of the invention will be described in more detail with reference to the accompanying drawings. Show it:

Fig. 2
a schematic, partially cutaway plan view of the sunshade after Fig. 1 ,

In Fig. 1 ist eine Sonnenschutzanlage 10 in der Form eines sog. Sonnensegels gezeigt. Ein Behang 12 einer solchen Sonnenschutzanlage 10 wird dabei in einem frei stehenden System aufgespannt, das nicht auf einem festen Unterbau, wie beispielsweise einem Wintergarten oder dergleichen oder mithilfe eines Tragrahmens aufgebaut ist.In Fig. 1 a sunshade system 10 is shown in the form of a so-called awning. A curtain 12 such a sunshade system 10 is clamped in a free-standing system that is not built on a solid base, such as a conservatory or the like or using a support frame.

Im Beispielsfall besteht der Behang 12 aus zwei dreiecksförmigen Tuchbereichen 14, die beide auf eine mittig angeordnete Wickelwelle 16 aufwickelbar sind. Beim Aufwickeln ergibt sich dabei ein wechselweises Aufwickeln der beiden Tuchlagen. An den spitzen Enden 18 der beiden dreiecksförmigen Tuchhälften ist jeweils ein Ende 20 eines Umlenkseiles 22 befestigt, das gemeinsam mit einer ersten Umlenkrolle 24, einer zweiten Umlenkrolle 26, einem Zugseil 28 sowie einem elektrischen Antriebsmotor 30 mit einer Wickelrolle 32 (siehe Fig. 2) eine Zugeinrichtung zum Ausfahren der Behanghälften bildet. Das Umlenkseil 22 ist dabei über die beiden Umlenkrollen 24, 26 umgelenkt, wobei an der ersten Umlenkrolle 24 ein Zugseilende festgelegt ist, das auf die auf der Welle des Antriebsmotors 30 sitzenden Wickelrolle 32 aufwickelbar ist. Die zweite Umlenkrolle 26 ist ortsfest angebracht, beispielsweise an einer Wand oder an einer sonstigen Halterung. Demgegenüber ist die erste Umlenkrolle 24 bei der gezeigten Ausführungsform frei auf einer Bahn zwischen der Wickelrolle 32 und der Wickelwelle 16 beweglich, wobei sie sich bei vollständig eingefahrenem Behang um die Ausfahrlänge eines Teilbereichs des Behangs bewegt. Da bei der gezeigten Ausführungsform nur ein Antrieb zur Bewegung in der Ausfahrrichtung vorgesehen ist und außerdem eine Straffung des Behangs 12 in der Ausfahrstellung vorzusehen ist, ist innerhalb der Wickelwelle 16 eine Federspannvorrichtung 34 vorgesehen, die derart vorgespannt ist, dass bereits in der eingefahrenen Stellung des Behangs 12 eine Vorspannkraft auf die Teilbereiche 14 des Behangs 12 in der Einfahrrichtung ausgeübt wird. Beim Ausfahren des Behangs wird die Federspannvorrichtung 34 weiter gespannt, wobei die Zunahme der Spannkraft durch die Ausbildung der Federspannvorrichtung 34 angepasst werden kann. So ist es beispielsweise durch lange Federwege möglich, einen nur relativ geringen Anstieg der Spannkraft zwischen der eingefahrenen und der ausgefahrenen Endstellung des Behangs einzustellen. Die Federspannvorrichtung 34 baut bei dieser Ausführungsform auch die in Einfahrrichtung notwendigen Antriebskräfte auf.In the example, the curtain 12 consists of two triangular cloth regions 14, both of which are wound on a centrally arranged winding shaft 16. When winding this results in a mutual winding of the two layers of cloth. At the pointed ends 18 of the two triangular cloth halves, one end 20 of a Umlenkseiles 22 is fixed, which together with a first guide roller 24, a second guide roller 26, a pull cable 28 and an electric drive motor 30 with a winding roller 32 (see Fig. 2 ) forms a pulling device for extending the hanging halves. The Umlenkseil 22 is over the two pulleys 24, 26th deflected, wherein at the first guide roller 24, a traction cable end is fixed, which is wound on the seated on the shaft of the drive motor 30 winding roller 32. The second deflection roller 26 is fixedly mounted, for example on a wall or on another holder. In contrast, in the embodiment shown, the first deflection roller 24 is freely movable on a path between the winding roller 32 and the winding shaft 16, wherein it moves around the extension length of a partial area of the curtain when the curtain is completely retracted. Since in the embodiment shown only one drive is provided for movement in the extension direction and also a tightening of the curtain 12 is provided in the extended position, a spring tensioning device 34 is provided within the winding shaft 16, which is biased such that already in the retracted position of Behangs 12 a biasing force is applied to the portions 14 of the curtain 12 in the retraction direction. When extending the curtain, the spring tensioning device 34 is further tensioned, wherein the increase of the clamping force can be adjusted by the formation of the spring tensioning device 34. For example, it is possible by long spring travel to adjust only a relatively small increase in the clamping force between the retracted and the extended end position of the curtain. The spring tensioning device 34 in this embodiment also builds up the drive forces necessary in the retraction direction.

Die Federspannvorrichtung besteht beispielsweise aus einer oder mehreren Spiralfedern 35, die zwischen feststehenden Lagerteilen 36, 38 und beweglichen Lagerteilen (nicht gezeigt) der Wickelwelle 16 angeordnet sind.The spring tensioning device consists for example of one or more coil springs 35, which are arranged between fixed bearing parts 36, 38 and movable bearing parts (not shown) of the winding shaft 16.

Damit ergibt sich eine Anordnung des als Sonnensegel ausgebildeten Behangs, die durch vier feststehende Punkte definiert ist, nämlich die beiden Lagerstellen 36, 38 der Wickelwelle 16, den Anbringungspunkt der zweiten Umlenkrolle 26 sowie die Lage der Wickelrolle 32.This results in an arrangement of the shade formed as a sun shade, which is defined by four fixed points, namely the two bearings 36, 38 of the winding shaft 16, the mounting point of the second guide roller 26 and the position of the winding roller 32nd

Das beschriebene Grundprinzip eines einzigen Zugseiles, das über zwei Umlenkrollen auf zwei Behanghälften wirkt, die gemeinsam auf einer einzigen Wickelwelle aufwickelbar sind, lässt sich aber auch auf andere Sonnenschutzanlagen mit Gegenzugsystem, wie z. B. Wintergartenmarkisen übertragen. So können beispielsweise die beiden Teilbereiche des Behangs rechteckig ausgebildet sein und an ihrem freien Ende mit jeweils einem Ausfahrprofil abschließen, das in seitlichen Führungsschienen geführt ist. Dort kann entsprechend dann auch ein Umlenkseil oder in beiden Führungsschienen jeweils ein Umlenkseil vorgesehen sein, wobei wiederum eine Umlenkung über jeweils eine ortsfeste und eine bewegliche Umlenkrolle erfolgt, die über ein Zugseil motorisch oder manuell verlagerbar ist.The basic principle of a single pull rope, which acts on two curtain halves via two pulleys, which can be wound together on a single winding shaft, but can also be applied to other sun protection systems with counter-pull system, such. B. winter garden awnings transferred. Thus, for example, the two partial areas of the hanging can be rectangular and terminate at their free end, each with an extension profile, which is guided in lateral guide rails. There may then be provided according to a Umlenkseil or guide rails in each case a deflection cable, in turn, a deflection via a stationary and a movable pulley, which is motorized or manually displaceable via a traction cable.

Der Antriebsmotor kann auch in der Wickelwelle sitzen und diese antreiben, wobei ein Abwickeln des Zugseiles von der Wickelrolle beim Einfahren des Behangs gegen eine auf die Wickelrolle wirkende Federspannvorrichtung erfolgt. Die Ausfahrbewegung des Behangs wird dann entsprechend durch die in der eingefahrenen Stellung vorgespannte Federspannvorrichtung bewerkstelligt. Grundsätzlich ist es auch möglich, die Wickelrolle auf der Drehachse der Wickelwelle anzuordnen und diese durch einen gemeinsamen Antriebsmotor anzutreiben. In einem solchen Fall arbeitet der Antriebsmotor sowohl in der Einfahr- als auch in der Ausfahrrichtung und die Federspannvorrichtung hat lediglich die Aufgabe, mit ihrer Vorspannung den Behang der Sonnenschutzanlage zu straffen. Entsprechend ist bei einem solchen Ausführungsbeispiel die Federspannvorrichtung innerhalb der Wickelwelle zwischen der Wickelrolle und der Wickelwelle angeordnet, um eine Relativdrehung zum Ausgleich bei den sich ändernden Wickeldurchmessern der Wickelwelle und der Wickelrolle zu schaffen. Bei einem Einsatz auch oder vor allem als Regenschutz, können statt reiner Behänge, z. B. auch Wachstücher, Kunststofffolien oder Planen zum Einsatz kommen.The drive motor can also sit in the winding shaft and drive it, with an unwinding of the pull cable from the winding roller during retraction of the curtain against a force acting on the winding roll spring tensioning device. The extension movement of the curtain is then accomplished accordingly by the biased in the retracted position spring tensioning device. In principle, it is also possible to arrange the winding roll on the axis of rotation of the winding shaft and to drive them by a common drive motor. In such a case, the drive motor operates both in the retracting and in the extension direction and the spring tensioning device has only the task of tightening the curtain of the sun protection system with its bias. Accordingly, in such an embodiment, the spring tensioning device is disposed within the winding shaft between the winding roll and the winding shaft to provide a relative rotation to compensate for the changing winding diameters of the winding shaft and the winding roll. When using or especially as a rain cover, instead of pure hangings, z. As also oilcloths, plastic films or tarpaulins are used.
