Description

Die Erfindung betrifft eine Sonnensegelvorrichtung, umfassend ein Sonnensegel mit zumindest einem eine Wölbung stabilisierenden Wölbungselement, zumindest eine Wickelwelle zum Auf- und Abwickeln des Sonnensegels und zumindest ein Zugseil.The invention relates to an awning device comprising an awning with at least one curvature stabilizing buckling element, at least one winding shaft for winding and unwinding the awning and at least one traction cable.

Derartige Sonnensegel dienen der Beschattung von Flächen, beispielsweise einem Gebäude vorgelagerte Terrassen oder Sitzreihen eines Stadions oder einer Rennbahn. Grundsätzlich umfasst eine solche Sonnensegelvorrichtung ein Sonnensegel, welches auf eine Wickelwelle auf- und abwickelbar ist.Such awnings serve the shading of surfaces, such as a building upstream terraces or rows of seats of a stadium or racetrack. In principle, such a sunshade device comprises an awning which can be wound up and unwound onto a winding shaft.

Die Wickelwelle wird in der Regel mittels eines Elektromotors angetrieben. Das Sonnensegel ist mit einer Kante an der Wickelwelle befestigt, sodass das Segel durch Drehung der Wickelwelle auf diese aufgewickelt, aber auch wieder abgewickelt werden kann. An der in etwa parallel zur befestigten Segelkante gegenüberliegenden freien Kante des Sonnensegels sind ein bis mehrere Zugseile verbunden, welche das Sonnensegel im abgewickelten Zustand als Schutzbedachung straffen. Das oder die Zugseile werden mithilfe eines oder mehrerer Gegenlager, die als Umlenkrollen ausgebildet sein können, umgelenkt. Diese Gegenlager können sich beispielsweise an Masten befinden, wobei an den freien Enden der so umgelenkten Zugseile dann Gewichte befestigt sein können, die das Seil mit Ihrem Gewicht konstant gespannt halten, indem sie einen entsprechenden Hub- und Senkweg verfügbar haben, auf dem sie sich entsprechend der jeweils von der Wickelwelle ab- oder auf- gewickelten Länge des Segels unter Beibehaltung der von Ihnen ausgeübten Zugkraft auf- und abbewegen können, wobei somit die konstante Spannkraft aus der auf die an den Zugseilen befestigten Gewichte wirkenden Gewichtskraft resultiert. Zusätzlich können ein- oder mehrere Flaschenzuganordnungen vorhanden sein, wodurch der verfügbare Hub- und Senkweg der Gewichte je nach baulichem Bedarf und Art der Zugseilinstallation verkleinert werden kann. Die Zugseile können jedoch auch mit jedweder dazu geeigneten Mechanik zeitgleich zum Ab- und Aufwickeln des Sonnensegels gespannt bzw. auch auf eine separate Wicklung auf und abgewickelt werden. Hierzu sind Bauweisen mit Wickelmotoren, Federzügen und pneumatischen Federn bekannt und in Verwendung.The winding shaft is usually driven by an electric motor. The awning is attached with an edge on the winding shaft, so that the sail wound by rotation of the winding shaft on this, but can also be unwound again. At the opposite approximately parallel to the fixed edge of the sail free edge of the awning one to several pull ropes are connected, which tighten the awning in the unwound state as a protective roofing. The one or more tension cables are deflected by means of one or more abutment which may be formed as pulleys. These abutments may be located, for example, on poles, with weights attached to the free ends of the deflected cables so as to keep the cable constantly tensioned with its weight by having available a corresponding lifting and lowering path on which to conform accordingly each of the length of the sail wound off or wound up from the winding shaft can move up and down while maintaining the traction force exerted by you, whereby the constant tension force thus results from the weight force acting on the weights attached to the traction ropes. In addition, one or more pulley arrangements may be present, whereby the available lifting and lowering travel of the weights can be reduced depending on the structural requirements and type of Zugseilinstallation. However, the traction cables can also be tensioned with any suitable mechanism at the same time for unwinding and winding up the awning or also on a separate winding on and unwound. These are Construction methods with winding motors, spring trains and pneumatic springs known and in use.

Darüber hinaus sind an dem Sonnensegel Wölbungselemente angeordnet, welche eine nach oben gerichtete Wölbung aufweisen, sodass dem Sonnensegel im abgewickelten Zustand eine nach oben gewölbte Form verliehen wird, wodurch Regenwasser abfließen kann und sich nicht auf dem Sonnensegel ansammelt. Diese Wölbungselemente sind in etwa parallel zu der Wickelwelle orientiert und werden beim Aufwickeln des Sonnensegels gerade gebogen, wenn sie in Kontakt mit der Wickelwelle gelangen. Beim Abwickeln des Sonnensegels nehmen diese aufgrund der aus ihrer Elastizität resultierenden Rückstellkräfte wieder die ursprüngliche gewölbte Form an.In addition, vaulting elements are arranged on the awning, which have an upward curvature, so that the awning in the unwound state is given an upwardly curved shape, whereby rainwater can flow away and does not accumulate on the awning. These buckling elements are oriented approximately parallel to the winding shaft and are just bent when winding the sun sail when they come into contact with the winding shaft. When unwinding the awning these take on due to the elasticity resulting from their restoring forces back to the original curved shape.

Aus der deutschen Offenlegungsschrift DE 10 2011 122 503 A1 ist eine Sonnensegelvorrichtung bekannt, bei welcher an der Wickelwelle zumindest ein Spannbügel angeordnet ist, wobei das Sonnensegel über den Spannbügel geführt wird. Der Spannbügel bewirkt, dass das Sonnensegel im abgewickelten Zustand nach oben gewölbt ist, sodass Regenwasser abfließen kann. Zusätzlich zu dem Spannbügel kann vorgesehen sein, dass das Sonnensegel quer zur Wickelrichtung orientierte Spannelemente aufweist, welche die durch den Spannbügel bereits ausgebildete gewölbte Form des Sonnensegels zusätzlich verstärken. Die Spannelemente erstrecken sich dabei über die gesamte Breite des Sonnensegels.From the German patent application DE 10 2011 122 503 A1 an awning device is known, in which at least one clamping bracket is arranged on the winding shaft, wherein the awning is guided over the clamping bracket. The tension bow causes the awning to be arched upwards in the unwound state so that rainwater can drain off. In addition to the tension bow can be provided that the awning has transverse to the winding direction oriented clamping elements, which additionally reinforce the already formed by the clamping bow arched shape of the awning. The clamping elements extend over the entire width of the awning.

Aus der deutschen Offenlegungsschrift DE 10 2011 122 502 A1 ist ebenfalls eine Sonnensegelvorrichtung bekannt, bei welcher in dem Sonnensegel quer zur Wickelrichtung orientierte bogenförmig vorgespannte Spannelemente angeordnet sind, welche dem Sonnensegel durch Ihre bogenförmige Vorspannung eine nach oben gewölbte Form verleihen, da die beim Abwickeln von der Welle sich dann bogenförmig entspannenden Spannelemente eine nach oben gewölbte Form aufweisen. Die Spannelemente erstrecken sich über die gesamte Breite des Sonnensegels.From the German patent application DE 10 2011 122 502 A1 is also an awning device is known in which in the awning transverse to the winding direction oriented arcuately biased clamping elements are arranged, which give the awning by your arcuate bias an upwardly curved shape, since the unwinding of the shaft then arcuately relaxing clamping elements one up have arched shape. The clamping elements extend over the entire width of the awning.

Aus der deutschen Offenlegungsschrift DE 10 2013 104 777 A1 ist eine Sonnensegelvorrichtung bekannt, welche beidseitig des Sonnensegels an der der Wickelwelle abgewandten Seite desselben befestigte Zugseile aufweist, welche jeweils an einem Mast über Rollen umgelenkt werden und beidseitig des Sonnensegels zu der Wickelwelle zurückgeführt werden, wobei die Zugseile jeweils auf eine auf der Wickelwelle angeordnete Rolle aufgewickelt bzw. von dieser abgewickelt werden. In den Masten ist jeweils ein Gewicht angeordnet, welches eine drehbar gelagerte Rolle aufweist, über welche das jeweilige Zugseil geführt ist.From the German patent application DE 10 2013 104 777 A1 An awning device is known, which on both sides of the awning on the winding shaft has opposite side of the same fixed traction cables, which are each deflected on a mast rollers and returned on both sides of the awning to the winding shaft, wherein the traction cables are each wound onto a roll arranged on the winding shaft or unwound from this. In each case a weight is arranged in the masts, which has a rotatably mounted roller over which the respective traction cable is guided.

Die DE 20 2013 105 201 U1 zeigt ein Segel mit gewölbten Spreizlatten.The DE 20 2013 105 201 U1 shows a sail with arched Spreizlatten.

Schließlich ist aus der internationalen Patentanmeldung WO 2015/022324 A1 eine Sonnensegelvorrichtung bekannt, welche beidseitig des Sonnensegels an der der Wickelwelle abgewandten Seite desselben befestigte Zugseile aufweist, welche jeweils auf eine an einem Mast drehbar gelagerte Rolle aufwickelbar bzw. von dieser abwickelbar sind, wobei zusätzlich jeweils eine Spannkraftvergleichseinrichtung vorhanden ist, welche bei einer Zugspannung, die größer ist als die Sollspannung, eine Verminderung des Zugseilvorrates und bei einer Zugspannung, die kleiner ist als die Sollspannung, eine Vergrößerung des Zugseilvorrates veranlasst. Dadurch wird sichergestellt, dass das Sonnensegel stets die vorgesehene Spannung aufweist, um einerseits auch bei einwirkendem Wind im Wesentlichen ortsfest gehalten zu sein und andererseits nicht durch eine zu große Spannung beschädigt zu werden.Finally, from the international patent application WO 2015/022324 A1 an awning device is known, which on both sides of the awning on the side facing away from the winding shaft of the same fixed tension cables, which are each wound on a rotatably mounted on a mast roll or unwound from this, wherein in addition in each case a Spannkraftvergleichseinrichtung is present, which at a tensile stress, which is greater than the target voltage, a reduction of Zugseilvorrates and at a tensile stress that is smaller than the target voltage, causes an increase in Zugseilvorrats. This ensures that the awning always has the intended voltage to be held on the one hand substantially stationary even when wind is acting and on the other hand not to be damaged by too high a voltage.

Bei den aus dem Stand der Technik bekannten Sonnensegelvorrichtungen stellt sich das Problem, dass die Sonnensegelflächen aufgrund einer fehlenden technischen Lösung in der Mitte nach unten durchhängen, was formal nicht schön ist, weil sich das Sonnensegel einem darunter Sitzenden entgegenwölbt. Aus diesem Grunde müssen solche Segel auch mit mindestens 15 Grad schräg angestellt installiert werden, damit Regenwasser ablaufen kann. Würde man diese Sonnensegel annähernd horizontal installieren, würden sich durch Regen sogenannte Wassersäcke ausbilden, in denen sich das Wasser sammelt und die Sonnensegel entweder zu Boden ziehen oder dieses aufgrund der Überlastung zerstören. Bei Anwendung der aus der Offenlegungsschrift DE 10 2011 122 502 A1 bekannten Wölbungstechnik für Sonnensegel ist die Breite des Sonnensegels dadurch begrenzt, dass die vorhandenen Wölbungselemente, welche im Stand der Technik auch als Spannelemente bezeichnet werden, ihre nach oben gewölbte Form nicht aufrechterhalten können, wenn das Sonnensegel zu breit ist.In the awning devices known from the prior art, there is the problem that the awning surfaces sag due to a lack of technical solution in the middle down, which is not formally beautiful, because the awning buckles a seated underneath. For this reason, such sails must be installed at an angle of at least 15 degrees, so that rainwater can run off. If one were to install these awnings approximately horizontally, so-called water sacks would form by rain, in which the water collects and the sun sails either pull to the ground or destroy this due to the overload. When applying the published patent application DE 10 2011 122 502 A1 known bulge technique for sun sails, the width of the awning is limited by the fact that the existing buckling elements, which in the State of the art may also be referred to as clamping elements, their upwardly curved shape can not be maintained if the awning is too wide.

Dabei ist auch zu berücksichtigen, dass die Wölbungs- bzw. Spannelemente aus einem dauerelastischen Leichtbaumaterial, wie glasfaserverstärktem Kunststoff (GFK), bestehen, damit diese beim Aufwickeln des Sonnensegels auf die Wickelwelle immer wieder gerade gebogen werden können und dadurch glatt an der Welle anliegend mit aufgewickelt werden können. Ein weiteres Problem ist, dass die bei derartiger Bauweise benötigten Spannelemente mit einer Bogenform sehr teuer und aufwendig zu fertigen sind, da sie einzeln und von Hand gebaut werden müssen, da es keine bekannte Maschine gibt, die derart lange, bogenförmig gespannte und dauerelastische Profile aus glasfaserverstärktem Kunststoff (GFK) oder Ähnlichem fertigen kann.It should also be noted that the buckling or clamping elements made of a permanently elastic lightweight construction material, such as glass fiber reinforced plastic (GRP), so that they can be bent straight when winding the awning on the winding shaft straight and thus smoothly fitting to the shaft with can be wound up. Another problem is that the clamping elements required with such a design are very expensive and expensive to manufacture with an arched form, since they must be built individually and by hand, since there is no known machine that so long, arcuately stretched and permanently elastic profiles glass fiber reinforced plastic (GRP) or the like can manufacture.

Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Sonnensegelvorrichtung anzugeben, deren Sonnensegel sowohl eine ungefähr mittige Wölbung nach oben zur sicheren Wasserabführung haben, als auch deutlich breiter als die bei dem aus dem Stand der Technik bekannten Sonnensegelvorrichtungen gebaut werden können, wodurch nicht nur die Beschattung bzw. der Regenschutz größerer Flächen möglich, sondern auch der Anwendungsbereich von Sonnensegelvorrichtungen vergrößert wird. Des Weiteren liegt Ihr die Aufgabe zu Grunde, eine Bauweise anzugeben, die ebenfalls die Ausbildung einer regensicheren, nach oben weisenden Wölbung des abgewickelten Sonnensegels aus der gestreckt auf der Wickelwelle aufliegenden Sonnensegelfläche deutlich günstiger und möglichst unter Verwendung maschinell vorgefertigter Standardhalbzeuge ermöglicht, wie zum Beispiel die Verwendung dauerelastischer aber stabiler, gerader GFK-Segellatten aus dem Segelsport.Against this background, the present invention seeks to provide an awning device, the awning both have an approximately central curvature upwards for safe water removal, as well as much wider than that can be built in the known from the prior art awning devices, which does not only the shading or the rain protection of larger areas possible, but also the scope of awning devices is increased. Furthermore, the task is based on specifying a construction, which also allows the formation of a rainproof, upward-facing curvature of the developed awning from the stretched on the winding shaft sunshade surface significantly cheaper and possible using machine-made standard semi-finished products, such as Use of permanently elastic but stable, straight GRP sail battens from the sailing sport.

Zur Lösung der Aufgabe ist vorgesehen, dass zumindest ein Zugseil mit einem ersten Bereich des Sonnensegels verbunden ist, wobei durch die Zugspannung des Zugseiles dieser erste Bereich zwischen der Wickelwelle und dem Zugseil im abgewickelten Zustand des Sonnensegels straff gespannt ist, und dass innerhalb dieses ersten Bereiches ein Abschnitt zumindest eines Wölbungselementes angeordnet ist, wobei das Wölbungselement dort in etwa parallel zur Wickelwelle angeordnet ist, dass das Sonnensegel zumindest einseitig des ersten Bereiches einen zweiten Bereich aufweist, in welchen hinein sich das zumindest eine Wölbungselement erstreckt, wobei der zweite Bereich auf dem zumindest einen Wölbungselement lose hängend gelagert ist, und dass das zumindest eine Wölbungselement im kräftefreien Zustand im Wesentlichen gerade ist oder wenigstens in einem Abschnitt eine nach unten weisende Wölbung aufweist, wobei der zweite Bereich des Sonnensegels weniger Flächenspannung in Zugrichtung zwischen Zugseil und Wickelwelle als der erste Bereich aufweist. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.To achieve the object, it is provided that at least one pull rope is connected to a first region of the awning, wherein tensioned by the tension of the pull rope this first area between the winding shaft and the pull rope in the developed state of the awning taut, and that within this first range a portion of at least one buckling element is arranged, wherein the buckling element is arranged there approximately parallel to the winding shaft, that the sun sail at least on one side of the first region has a second region, in which extends the at least one buckling element, wherein the second area on the at least one buckle element is mounted to hang loosely, and that the at least one buckle element in the force-free state is substantially straight or at least in a section has a downward curvature, wherein the second region of the awning less surface tension in the pulling direction between pull rope and Winding shaft than the first region has. Further advantageous embodiments of the invention will become apparent from the dependent claims.

Erfindungsgemäß ist damit vorgesehen, dass das Sonnensegel im abgewickelten Zustand einen straff gespannten ersten Bereich aufweist. Dazu ist mit dem ersten Bereich des Sonnensegels zumindest ein Zugseil, vorzugsweise jedoch mehrere Zugseile, verbunden, welche in der aus dem Stand der Technik bekannten Weise über zumindest ein Gegenlager, beispielsweise eine Umlenkrolle, zu einem das Zugseil unter die benötigte Zugspannung setzenden und dieses aufnehmenden und abgebenden Seilzugmechanismus umgelenkt werden. Über die Zugseile wird eine Spannkraft auf den ersten Bereich des Sonnensegels ausgeübt, sodass dieser konstant straff gespannt ist. In oder auf dem Sonnensegel ist darüber hinaus zumindest ein Wölbungselement, vorzugsweise mehrere in Wickelrichtung beabstandete Wölbungselemente, in etwa parallel zur Wickelwelle angeordnet, welche dem Sonnensegel eine nach oben gewölbte Form verleihen, sodass Regenwasser abfließen kann. Zumindest einseitig des ersten Bereiches des Sonnensegels ist ein zweiter Bereich vorhanden, in welchen hinein sich das zumindest eine Wölbungselement erstreckt. Mit diesem zweiten Bereich sind keine Zugseile verbunden, sodass auf den zweiten Bereich auch keine direkte Spannkraft ausgeübt wird und dort die Flächenspannung deutlich geringer als im ersten Bereich ist. Dadurch wird erreicht, dass keine Spannkraft gegen die auf den sich in den zweiten Bereich des Sonnensegels hinein erstreckenden Abschnitt des Wölbungselementes wirkende Gewichtskraft wirkt, was zur Folge hat, dass der sich in den zweiten Bereich des Sonnensegels hinein erstreckende Abschnitt des Wölbungselementes durch die Gewichtskraft nach unten gezogen wird. Dadurch nimmt das Wölbungselement eine nach oben gewölbte Form an, ohne dass es im kräftefreien Zustand bereits eine nach oben gewölbte Form haben muss, oder in dem Sonnensegel unter einer in eine gebogene oder gewölbte Form resultierenden Vorspannung stehen muss. Stattdessen ist das zumindest eine Wölbungselement gemäß der Erfindung im kräftefreien Zustand ungewölbt, d.h. gerade, oder weist wenigstens in einem Abschnitt eine nach unten weisende Wölbung auf. Dies ist ein wesentlicher Aspekt der vorliegenden Erfindung. Hierdurch kann nämlich das Wölbungselement deutlich länger ausgebildet sein, da es die Wölbung nicht durch eine Eigenwölbung nach oben heraus tragen muss, sondern stattdessen durch die unterschiedlichen Spannkräfte in den Bereichen des Sonnensegels und die Gewichtskraft in dem derart gespannten Sonnensegel automatisch eine nach oben gewölbte Form annimmt und damit dem Sonnensegel eine nach oben gewölbte Form verleiht. Es kann dabei ein Wölbungselement verwendet werden, welches im kräftefreien Zustand ungewölbt, d.h. gerade, ist. Es kann darüber hinaus ein Wölbungselement verwendet werden, welches in wenigstens einem Abschnitt eine nach unten weisende Wölbung aufweist, in welcher Ausgestaltung das Wölbungselement noch länger ausgeführt sein kann.According to the invention, it is thus provided that the awning has a tautly stretched first region in the unwound state. For this purpose, at least one traction cable, but preferably a plurality of traction cables, connected in the manner known from the prior art via at least one counter-bearing, for example a deflection roller, to a tensioning cable under the required tension setting and receiving this and donating cable mechanism are deflected. The tension cables exert a tension force on the first area of the awning so that it is constantly taut. In or on the awning, moreover, at least one buckling element, preferably a plurality of buckling elements spaced apart in the winding direction, is arranged approximately parallel to the winding shaft, which gives the awning an upwardly curved shape, so that rainwater can run off. At least on one side of the first region of the awning, there is a second region into which the at least one bulging element extends. No tension cables are connected to this second area, so that no direct tensioning force is exerted on the second area and there the surface tension is significantly lower than in the first area. It is thereby achieved that no clamping force acts against the weight force acting on the portion of the arching element extending into the second region of the awning, with the result that the section of the arching element extending into the second region of the solar sail deflects by the weight force pulled down. As a result, the arching element assumes an upwardly curved shape, without it having to have an upwardly curved shape in the force-free state or in which the solar sail must be under a bias that results in a curved or arched shape. Instead, this is at least one buckling element according to the invention in non-corrosive state non-arched, ie straight, or has at least in a section on a downwardly facing curvature. This is an essential aspect of the present invention. In this way, namely, the curvature element can be formed much longer, since it does not have to carry out the curvature by an inherent curvature upwards, but instead automatically assumes an upwardly curved shape by the different clamping forces in the areas of the awning and the weight in the sun sail so taut and thus gives the awning an upwardly curved shape. It can be used a curvature element which is non-arched in the force-free state, ie straight. In addition, a curvature element can be used, which in at least one section has a downwardly pointing curvature, in which configuration the curvature element can be made even longer.

Wie bereits zuvor beschrieben, ist die Länge von Wölbungselementen bei den aus dem Stand der Technik bekannten Sonnensegelvorrichtungen dadurch begrenzt, dass sie ihre nach oben gewölbte Form aufgrund der auf sie wirkenden Gewichtskraft und der auf das Sonnensegel wirkenden Zugspannung verlieren, wenn sie zu lang sind. Um diesen Effekt zu vermeiden, könnten die Wölbungselemente aus einem massiveren Material bestehen. Allerdings müssen die Wölbungselemente beim Aufwickeln des Sonnensegels auf die Wickelwelle durch diese gerade gebogen werden, wobei dann erheblich größere Kräfte aufgewendet werden müssten und darüber hinaus die Gefahr bestünde, dass sich in dem Sonnensegel beim Aufwickeln Risse bilden. Auch in dem Fall, dass die Wölbungselemente gerade ausgeführt sind und in das Sonnensegel mit einer Vorspannung eingearbeitet sind, sodass die Wölbungselemente eine nach oben gewölbte Form annehmen, stellt sich dieses Problem, da bei zunehmender Länge der Wölbungselemente eine immer größere durch das Sonnensegel auszuübende Vorspannung erforderlich ist, um sicherzustellen, dass die Wölbungselemente in dem Sonnensegel nach oben gewölbt sind und es auch bleiben, da bei den aus dem Stand der Technik bekannten Ausgestaltungen von Sonnensegelvorrichtungen die auf die Wölbungselemente wirkende Gewichtkraft und die auf das Sonnensegel wirkende Zugspannung stets der nach oben gewölbten Form entgegenwirkt.As previously described, the length of buckling elements in the prior art awning devices is limited in that they lose their upwardly curved shape due to the gravitational force acting on them and the tension acting on the awning if they are too long. To avoid this effect, the arching elements could be made of a more massive material. However, the buckling elements when winding the awning on the winding shaft must be bent straight through this, in which case considerably larger forces would have to be expended and, moreover, there would be the danger that form cracks in the awning during winding. Also, in the case that the buckling elements are straight and are incorporated into the awning with a bias, so that the buckling elements assume an upwardly curved shape, this problem arises because with increasing length of the buckling elements an ever greater to be exerted by the awning bias is necessary to ensure that the buckling elements in the awning are curved upwards and remain so, since in the known from the prior art embodiments of awning devices acting on the buckling elements weight force and acting on the awning tension always upwards opposes arched shape.

Dagegen wird bei der erfindungsgemäßen Sonnensegelvorrichtung die nach oben gewölbte Form gerade durch die wirkende Gewichtskraft erreicht, weswegen die Wölbungselemente deutlich länger ausgeführt sein können und damit Sonnensegel mit deutlich größerer Breite realisiert werden können.By contrast, in the awning device according to the invention, the upwardly curved shape is achieved precisely by the acting weight force, which is why the arching elements can be made significantly longer and thus sun sails can be realized with a significantly greater width.

Vorzugsweise ist beidseitg des ersten Bereiches jeweils ein zweiter Bereich angeordnet und das zumindest eine Wölbungselement erstreckt sich beidseitig des ersten Bereiches über diesen hinaus in die zweiten Bereiche, sodass die gewölbte Form des Wölbungselementes durch die auf beide Endabschnitte desselben wirkende Gewichtskraft erreicht wird.Preferably, a second region is arranged on both sides of the first region, and the at least one bulging element extends beyond the first region beyond the second region, so that the curved shape of the bulging element is achieved by the weight force acting on both end sections thereof.

Um zu erreichen, dass der zumindest eine zweite Bereich des Sonnensegels nicht straff gespannt ist und der sich in diesen hinein erstreckende Abschnitt des zumindest einen Wölbungselementes nach unten bewegen kann, um dem Wölbungselement die gewünschte nach oben gewölbte Form zu verleihen, kann vorgesehen sein, dass der zweite Bereich zumindest eine Stoffzugabe aufweist. Durch diese Stoffzugabe wird verhindert, dass der zweite Bereich zu straff gespannt ist. Vorzugsweise ist vorgesehen, dass mehrere Wölbungselemente und mehrere Stoffzugaben vorhanden sind, welche ein- oder beidseitig der Wölbungselemente angeordnet sind. In dieser Ausgestaltung erstreckt sich das Wölbungselement jeweils mit einem Abschnitt in eine in jedem zweiten Bereich ausgebildete Stoffzugabe, wodurch diese Abschnitte der Gewichtskraft nach unten nachgeben können.In order to achieve that the at least one second region of the awning is not taut and the portion of the at least one buckling element extending into it can move downwardly to give the buckling element the desired upwardly curved shape, it can be provided that the second region has at least one added substance. This addition of the substance prevents the second area from being stretched too tightly. It is preferably provided that a plurality of arching elements and a plurality of fabric additions are provided, which are arranged on one or both sides of the arching elements. In this embodiment, the arching element extends in each case with a portion in a fabric addition formed in each second region, whereby these portions of the weight force can yield downward.

Ferner kann vorgesehen sein, dass eine an die Wickelwelle angrenzende Stoffzugabe vorhanden ist, damit sich der in den zweiten Bereich des Sonnensegels hineinragende Abschnitt des Wölbungselementes und der zweite Bereich des Sonnensegels entlang der in etwa gerade verlaufenden Wickelwelle spannungsfrei und der Schwerkraft folgend nach unten bewegen kann, um die Wölbung zur Mitte der Wickelwelle hin auszubilden, ohne vom Sonnensegel selber oben gehalten zu werden.Furthermore, provision can be made for a substance addition adjoining the winding shaft to be present, so that the section of the arching element projecting into the second region of the solar sail and the second region of the solar sail can move downwards along the approximately straight winding shaft and free of gravity to form the bulge toward the center of the winding shaft, without being held up by the awning itself.

Die Stoffzugaben sind vorzugsweise im Wesentlichen dreieckförmig ausgebildet, sodass die Spannung des zweiten Bereiches von seiner dem ersten Bereich zugewandten Seite zu seiner dem ersten Bereich abgewandten Seite kontinuierlich abnimmt. Vorzugsweise werden die Übergänge zwischen den Stoffzugaben und dem in etwa gerade und parallel zur Wickelwelle verlaufendem Stoffbahnzuschnitt in einem Radius abgerundet, um hier einen fließenden Übergang ohne spätere Zugfalten zu schaffen.The fabric additions are preferably formed substantially triangular, so that the voltage of the second region of its facing the first region Side to its side facing away from the first area continuously decreases. Preferably, the transitions between the fabric additions and the fabric cut extending approximately straight and parallel to the winding shaft are rounded off in a radius, in order to create a smooth transition without subsequent tension folds.

Alternativ zu den Stoffzugaben kann vorgesehen sein, dass das Sonnensegel in dem zweiten Bereich eine größere Elastizität zumindest in Zugrichtung aufweist als in dem ersten Bereich, wobei der zweite Bereich eine unidirektionale oder bidirektionale Elastizität aufweisen kann. Auch durch eine größere Elastizität des zweiten Bereiches gegenüber derjenigen des ersten Bereiches wird erreicht, dass sich der in den zweiten Bereich erstreckende Abschnitt des zumindest einen Wölbungselementes, vorzugsweise der mehreren Wölbungselemente, durch Einwirkung der Gewichtskraft nach unten bewegen kann, wodurch dem Wölbungselement die gewünschte nach oben gewölbte Form verliehen wird.As an alternative to the additions of material, provision may be made for the awning to have greater elasticity in the second region, at least in the direction of pull, than in the first region, wherein the second region may have unidirectional or bidirectional elasticity. It is also achieved by a greater elasticity of the second region compared to that of the first region that the portion of the at least one arching element extending in the second region, preferably of the plurality of arching elements, can move downward by the action of the force of gravity, whereby the desired curvature of the arching element above arched shape is awarded.

In bevorzugter Ausgestaltung der erfindungsgemäßen Sonnensegelvorrichtung ist vorgesehen, dass mehrere Wölbungselemente vorhanden sind, wobei zusätzlich ein äußeres Wölbungselement vorhanden sein kann, welches knickbar ausgebildet ist und/oder eine gewölbte Form aufweist. Wie mit Blick auf die Figuren deutlich wird, nimmt die Breite des zweiten Bereiches in Richtung der von der Wickelwelle abgewandten Seite des Sonnensegels ab und geht schließlich gegen Null, weswegen einem äußeren Wölbungselement nicht in der zuvor geschilderten Weise eine nach oben gewölbte Form verliehen werden kann. Damit das äußere Wölbungselement dennoch diese Form annimmt, kann es knickbar ausgebildet sein, sodass es aufgrund der durch die übrigen Wölbungselemente bewirkten, nach oben gewölbten Form des Sonnensegels nach oben abknickt und sich dadurch an die Form der übrigen Wölbungselemente im belasteten Zustand anpasst.In a preferred embodiment of the awning device according to the invention it is provided that a plurality of buckling elements are present, wherein in addition an outer buckling element may be present, which is formed kinkable and / or has a curved shape. As can be seen with reference to the figures, the width of the second region decreases in the direction of the side facing away from the winding shaft side of the awning and finally goes to zero, so an outer curvature element can not be imparted in the manner previously described an upwardly curved shape , So that the outer curvature element nevertheless assumes this shape, it can be designed to be bendable, so that it bends upward due to the curvature of the awning caused by the other curvature elements and thereby adapts to the shape of the remaining curvature elements in the loaded state.

In dem zweiten Bereich angeordnete Stoffzugaben oder auch eine größere Elastizität des zweiten Bereiches kann dazu führen, dass das Sonnensegel nicht mehr gleichmäßig aufgewickelt wird, wenn das Sonnensegel über seine gesamte Breite durch eine Wickelwelle gleicher Wickelgeschwindigkeit und gleichen Durchmessers aufgewickelt wird. Zur Lösung dieses Problems kann vorgesehen sein, dass in dem zweiten Bereich des Sonnensegels zumindest ein sich im Wesentlichen in Wickelrichtung erstreckendes Federelement eingelassen ist. Vorzugsweise ist dieses Federelement in dem Saum des zweiten Bereiches des Sonnensegels eingelassen. Besonders bevorzugt besteht das Federelement aus Federstahl. Das Federelement wirkt aufgrund seiner Elastizität einer Aufwicklung entgegen, was im Falle einer durch eine angetriebene Wickelwelle erfolgte Aufwicklung zur Folge hat, dass sich das Federelement nicht an die Wickelwelle oder das bereits aufgewickelte Sonnensegel anschmiegt, sondern sich von dieser bzw. diesen abhebt und die Wickelwelle nach mehreren Umdrehungen derselben in Form einer Spirale umgibt. Dadurch wiederum wird der Wickeldurchmesser erhöht, sodass der Wickeldurchmesser, mit welchem der zweite Bereich aufgewickelt wird, größer ist als der Wickeldurchmesser, mit welchem der erste Bereich aufgewickelt wird. Hierdurch wird das Sonnensegel über seine gesamte Breite gleichmäßig aufgewickelt, trotz dass in dem zweiten Bereich Stoffzugaben vorhanden sind oder dieser eine größere Elastizität aufweist. Die Vergrößerung des Wickeldurchmessers entspricht dabei genau den Abmessungen der Stoffzugaben in Wickelrichtung bzw. des Elastizitätsunterschiedes zwischen dem ersten Bereich und dem zweiten Bereich, da einer weiteren Vergrößerung des Wickeldurchmessers dann entgegengewirkt wird, wenn die Spannung des zweiten Bereiches der Rückstellkraft des Federelementes die Waage hält.Arranged in the second region additions of material or even greater elasticity of the second region can cause the awning is no longer wound evenly when the awning over its entire width by a winding shaft of the same winding speed and the same diameter wound becomes. To solve this problem, it may be provided that at least one spring element extending essentially in the winding direction is embedded in the second region of the solar sail. Preferably, this spring element is embedded in the seam of the second region of the awning. Particularly preferably, the spring element consists of spring steel. The spring element counteracts a winding due to its elasticity, which in the case of a winding carried by a driven winding has the consequence that the spring element does not conform to the winding shaft or the already wound awning, but stands out from this and this and the winding shaft after several turns of the same surrounds in the form of a spiral. As a result, in turn, the winding diameter is increased, so that the winding diameter, with which the second area is wound, is greater than the winding diameter with which the first area is wound up. As a result, the awning is wound evenly over its entire width, despite the fact that in the second area fabric additions are present or this has a greater elasticity. The enlargement of the winding diameter corresponds exactly to the dimensions of the fabric additions in the winding direction and the elasticity difference between the first region and the second region, since a further increase in the winding diameter is then counteracted when the voltage of the second region of the restoring force of the spring element holds the balance.

Dieses Problem kann in einer alternativen Ausgestaltung auch dadurch gelöst werden, dass die Wickelwelle mehrere Abschnitte aufweist, wobei der Abschnitt, welcher zur Aufwicklung des zweiten Bereiches vorgesehen ist, einen entsprechend größeren Durchmesser aufweist als der Abschnitt, welcher zur Aufwicklung des ersten Bereiches vorgesehen ist. In dieser Ausgestaltung weist die Wickelwelle mehrere Abschnitte unterschiedlichen Durchmessers auf, wobei dem ersten Bereich des Sonnensegels ein Abschnitt mit kleinerem Durchmesser der Wickelwelle zugeordnet ist als dem zumindest einen zweiten Bereich des Sonnensegels.This problem can also be solved in an alternative embodiment in that the winding shaft has a plurality of sections, wherein the portion which is provided for winding the second area, has a correspondingly larger diameter than the portion which is provided for winding the first area. In this embodiment, the winding shaft has a plurality of sections of different diameters, wherein a portion of smaller diameter of the winding shaft is associated with the first region of the solar sail as the at least a second portion of the solar sail.

Das genannte Problem kann auch dadurch gelöst werden, dass die Wickelwelle mehrere Abschnitte aufweist, wobei der Abschnitt, welcher zur Abwicklung des zweiten Bereiches vorgesehen ist, mit größerer Wickelgeschwindigkeit drehbar ausgebildet ist als der Abschnitt, welcher zur Aufwicklung des ersten Bereiches vorgesehen ist. In dieser Ausgestaltung ist dem ersten Bereich des Sonnensegels ein Abschnitt der Wickelwelle zugeordnet, welcher eine geringe Wickelgeschwindigkeit aufweist als der dem zumindest einen zweiten Bereich zugeordnete Abschnitt der Wickelwelle. Die unterschiedlichen Wickelgeschwindigkeiten der Abschnitte der Wickelwelle können dadurch realisiert werden, dass die Abschnitte von einer Antriebseinrichtung antreibbar sind, welche mit ein oder mehreren innerhalb oder außerhalb der Wickelwelle angeordneten Getrieben zusammenwirkt, oder dass die Abschnitte von unabhängigen Antriebseinrichtungen antreibbar sind. In der erstgenannten Alternative kann jedem Abschnitt ein Getriebe zugeordnet sein, dessen Übersetzungsverhältnis so gewählt ist, dass die gewünschten Wickelgeschwindigkeiten eingestellt sind. Es besteht aber auch die Möglichkeit, jeweils zwei Abschnitte einer Wickelwelle über ein Getriebe mit dem entsprechenden Übersetzungsverhältnis zu verbinden und nur einen Abschnitt der Wickelwelle mittels einer Antriebseinrichtung anzutreiben. Durch das zwischen zwei Abschnitten der Wickelwelle angeordnete Getriebe mit entsprechendem Übersetzungsverhältnis wird die mittels der Antriebseinrichtung bewirkte Rotation eines Abschnittes auf den benachbarten Abschnitt übertragen, wobei jedoch aufgrund des Übersetzungsverhältnisses die Wickelgeschwindigkeiten der Abschnitte unterschiedlich sind. Natürlich kann auch vorgesehen sein, dass die Abschnitte der Wickelwelle von unabhängigen Antriebseinrichtungen antreibbar sind, welche den jeweiligen Abschnitt mit der gewünschten Wickelgeschwindigkeit in Rotation versetzen.The above problem can also be solved in that the winding shaft has a plurality of sections, wherein the portion which for the development of the second Region is provided rotatably formed with a larger winding speed than the portion which is provided for winding the first region. In this embodiment, the first area of the awning is associated with a portion of the winding shaft, which has a low winding speed than the portion of the winding shaft associated with the at least one second region. The different winding speeds of the sections of the winding shaft can be realized in that the sections can be driven by a drive device which cooperates with one or more gears arranged inside or outside the winding shaft, or in that the sections can be driven by independent drive devices. In the former alternative, each section may be assigned a gear whose transmission ratio is selected so that the desired winding speeds are set. But it is also possible to connect two sections of a winding shaft via a gear with the corresponding gear ratio and to drive only a portion of the winding shaft by means of a drive device. By arranged between two portions of the winding shaft gearbox with a corresponding ratio, the effected by means of the drive means rotation of a section is transmitted to the adjacent section, but due to the transmission ratio, the winding speeds of the sections are different. Of course, it can also be provided that the sections of the winding shaft can be driven by independent drive means, which set the respective section at the desired winding speed in rotation.

Eine Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung wird im Nachfolgenden anhand der Figuren nochmals erläutert.An embodiment of the awning device according to the invention will be explained again below with reference to FIGS.

Figur 1 zeigt in einer perspektivischen Ansicht eine erste Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung 1, umfassend eine Wickelwelle 2, ein Sonnensegel 3, Zugseile 4, welche über nicht dargestellte Gegenlager umgelenkt werden, mehrere Wölbungselemente 5 und ein äußeres Wölbungselement 9. Das Sonnensegel besteht aus einem ersten Bereich 6 und zwei zweiten Bereichen 7, welche beidseitig des ersten Bereiches 6 angeordnet sind. Die Übergänge zwischen dem ersten Bereich und den zweiten Bereichen 7 sind als Linien 14 dargestellt. Die Wölbungselemente 5 sind in dem ersten Bereich 6 des Sonnensegels 3 angeordnet und erstrecken sich beidseitig in die zweiten Bereiche 7, welche jeweils nähere Stoffzugaben 8 aufweisen. Die Stoffzugaben 8 sind beidseitig der sich in die zweiten Bereiche 7 hineinerstreckenden Abschnitte der Wölbungselemente 5 angeordnet. Die Wölbungselemente 5 selbst weisen in dieser Ausführungsform in kräftefreiem, das heißt unbelasteten Zustand, eine ungewölbte Form auf und wölben sich nur aufgrund der auf die in die zweiten Bereiche 7 hineinragenden Abschnitte der Wölbungselemente 5 wirkenden Gewichtskraft. Diese Wirkung ist im ersten Bereich 6 des Sonnensegels 3 aufgrund der Spannung des ersten Bereiches 6, welche durch die Zugseile 4 ausgeübt wird, einerseits und der Tatsache, dass die zweiten Bereiche 7 nicht straff gespannt sind, andererseits erreicht. FIG. 1 shows a perspective view of a first embodiment of the awning device 1 according to the invention, comprising a winding shaft 2, a sun sail 3, traction cables 4, which are deflected by abutment, not shown, a plurality of buckling elements 5 and an outer buckling element 9. The sun sail consists of a first area. 6 and two second regions 7, which are arranged on both sides of the first region 6. The transitions between the first region and the second regions 7 are shown as lines 14. The buckling elements 5 are arranged in the first region 6 of the awning 3 and extend on both sides in the second regions 7, which each have closer Stoffzugaben 8. The fabric additions 8 are arranged on both sides of the sections extending into the second regions 7 of the arching elements 5. The buckling elements 5 themselves have in this embodiment in force-free, ie unloaded state, a non-curved shape and bulge only due to the weight acting on the protruding into the second portions 7 portions of the buckling elements 5 weight. This effect is achieved in the first area 6 of the awning 3, on the one hand, and on the other hand because of the tension of the first area 6, which is exerted by the tension cables 4, on the one hand, and the fact that the second areas 7 are not taut.

Das äußere Wölbungselement 9 ist in dieser Ausführungsform im kräftefreiem Zustand ebenfalls ungewölbt und nimmt nur aufgrund der Spannung innerhalb des ersten Bereiches 6 eine nach oben gewölbte Form an, wobei das äußere Wölbungsprofil 9 zu diesem Zwecke einen geringeren Querschnitt aufweisen kann. Natürlich besteht auch die Möglichkeit ein äußeres Wölbungselement 9 zu verwenden, welches bereits im kräftefreiem Zustand eine nach oben gewölbte Form aufweist. Weiter besteht die Möglichkeit ein knickbares äußeres Wölbungselement 9 zu verwenden. Damit die Aufwicklung des Sonnensegels 3 auf die Wickelwelle 2 gleichmäßig erfolgen kann, ist in dem Saum 10 jedes zweiten Bereiches 7 ein Federstahldraht eingelassen, welcher aufgrund seiner federnden Elastizität eine Vergrößerung des Wickeldurchmessers auf den den zweiten Bereichen 7 zugeordneten Abschnitten der Wickelwelle 2 bewirkt. Dabei wird der Federstahldraht spiralförmig um die Wickelwelle 2 gewickelt, wobei die Wickellagen des Federstahldrahtes durch die gegen seine Verbiegung wirkende Rückstellkraft nicht aufeinander liegen, sondern voneinander beabstandet sind, was wiederum die geschilderte Vergrößerung des Wickeldurchmessers zur Folge hat.In this embodiment, the outer arching element 9 is also non-arched in the force-free state and only assumes an upwardly arched shape due to the tension within the first region 6, wherein the outer arched profile 9 may have a smaller cross-section for this purpose. Of course, it is also possible to use an outer curvature element 9, which has an upwardly curved shape even in the force-free state. Furthermore, it is possible to use a bendable outer curvature element 9. So that Winding of the awning 3 can be done evenly on the winding shaft 2, a spring steel wire is embedded in the seam 10 of each second area 7, which causes an increase in the winding diameter on the second regions 7 associated sections of the winding shaft 2 due to its elastic resilience. In this case, the spring steel wire is wound spirally around the winding shaft 2, wherein the winding layers of the spring steel wire are not superposed by the restoring force acting against its bending, but are spaced apart, which in turn has the described increase in the winding diameter result.

In den zweiten Bereichen 7 ist jeweils ein Federelement 11 vorhanden, bei welchem es sich um einen Federstahldraht handelt und welches den Wickeldurchmesser in den zweiten Bereichen 7 vergrößert, sodass diese zusammen mit dem ersten Bereich 6 gleichmäßig aufgewickelt werden können.In each case a spring element 11 is present in the second regions 7, in which case it is a spring steel wire and which enlarges the winding diameter in the second regions 7 so that they can be wound up uniformly together with the first region 6.

Figur 2 zeigt die erste Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung 1 in einer Draufsicht. Die Stoffzugaben 8 in den zweiten Bereichen 7 sind dreieckförmig ausgebildet und sind beidseitig der in die zweiten Bereiche 7 hineinragenden Abschnitte der Wölbungselemente 5 angeordnet, wobei die Länge der Stoffzugaben 8 in Wickelrichtung ausgehend von den dem ersten Bereich 6 zugewandten Seiten der zweiten Bereiche 7 in Richtung der dem ersten Bereich 6 abgewandten Seiten der zweiten Bereiche 7 zunimmt. Ferner ist in jedem zweiten Bereich 7 eine an die Wickelwelle 2 angrenzende Stoffzugabe 8 vorhanden, welche ebenfalls dreieckförmig ausgebildet ist. FIG. 2 shows the first embodiment of the awning device 1 according to the invention in a plan view. The fabric additions 8 in the second regions 7 are triangular in shape and are arranged on both sides of the protruding into the second portions 7 portions of the buckling elements 5, wherein the length of Stoffzugaben 8 in the winding direction, starting from the first region 6 facing sides of the second regions 7 in the direction the side of the second regions 7 facing away from the first region 6 increases. Furthermore, in each second area 7, a fabric addition 8 adjoining the winding shaft 2 is present, which likewise has a triangular shape.

Figur 3 zeigt eine Frontansicht der ersten Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung 1. Der erste Bereich 6 ist aufgrund der durch die Zugseile 4 ausgeübten Zugkraft straff gespannt. Die zweiten Bereiche 7 sind aufgrund der in ihnen angeordneten Stoffzugaben 8 nicht straff gespannt, sodass sich die in die zweiten Bereiche 7 hineinragenden Abschnitte der Wölbungselemente 5 durch die auf sie wirkende Gewichtskraft nach unten bewegen und so die Wölbungselemente 5 eine nach oben gewölbte Form annehmen. Das äußere Wölbungselement 9 passt sich der gewölbten Form des ersten Bereiches 6 an, kann aber auch seinerseits bereits im kräftefreien Zustand eine gewölbte Form aufweisen. Durch die auf die Endabschnitte der Wölbungselemente 5 wirkende Gewichtskraft, bewegen sich diese nach unten, wodurch eine nach oben weisende Wölbung der Wölbungselemente 5 erreicht wird. Der Punkt 15 wirkt als Drehpunkt für die nach unten weisende Bewegung 19 und die nach oben weisende Bewegung 16. Beide Bewegungen jedes Wölbungselementes 5 resultieren aus der auf die Endabschnitte der Wölbungselemente 5 wirkenden Gewichtskraft. FIG. 3 shows a front view of the first embodiment of the awning device according to the invention 1. The first region 6 is taut due to the force exerted by the traction cables 4 traction. The second regions 7 are not stretched tight due to the substance additions 8 arranged in them, so that the sections of the arching elements 5 projecting into the second regions 7 move downward due to the gravitational force acting on them and thus the arching elements 5 assume an upwardly curved shape. The outer arching element 9 adapts to the arched shape of the first region 6, but can in turn already in the force-free state have a curved shape. By acting on the end portions of the buckle elements 5 weight force, they move downward, whereby an upward-facing curvature of the buckling elements 5 is achieved. The point 15 acts as a fulcrum for the downward movement 19 and the upward movement 16. Both movements of each buckling element 5 result from the force acting on the end portions of the buckling elements 5 weight.

Figur 4 zeigt die erste Ausführungsform der Sonnensegelvorrichtung in einer Seitenansicht. FIG. 4 shows the first embodiment of the awning device in a side view.

In Figur 5 ist eine zweite Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung 20 gezeigt. Diese weist gegenüber der ersten Ausführungsform zusätzlich einen als Rampe für die Wölbungselemente 5 wirkenden Federwinkel 30 auf. Dieser besteht aus einem elastischen Material, beispielsweise Federstahl, und unterstützt die Aufrichtung der Wölbungselemente 5, wenn sie sich der Wickelwelle 2 nähern, sodass der erste Bereich 6 beim Aufwickeln entlastet wird und zusätzlich Vibrationen der Wölbungselemente 5 beim Aufwickeln vermieden werden. Der Federwinkel kann in der Nähe der Wickelwelle 2 an einer Wand befestigt sein. Ferner weisen die zweiten Bereiche 7 der Wickelwelle 2 zugewandte Ausnehmungen auf.In FIG. 5 a second embodiment of the awning device 20 according to the invention is shown. This has in addition to the first embodiment in addition to acting as a ramp for the buckling elements 5 spring angle 30. This consists of an elastic material, such as spring steel, and supports the erection of the buckling elements 5, as they approach the winding shaft 2, so that the first portion 6 is relieved during winding and in addition vibrations of the buckling elements 5 are avoided during winding. The spring angle can be fastened in the vicinity of the winding shaft 2 to a wall. Furthermore, the second regions 7 of the winding shaft 2 facing recesses.

Figur 6 zeigt eine dritte Ausführungsform der erfindungsgemäßen Sonnensegelvorrichtung 40. Diese weist nur ein Wölbungselement 5 auf und eine andere Form der zweiten Bereiche auf. Die Bereiche A, B, C, D, E und F sind Bereiche in denen sich Abschnitte des Sonnensegels überlappen. In diesen Bereichen sind die verschiedenen Abschnitte des Sonnensegels miteinander vernäht. FIG. 6 shows a third embodiment of the awning device 40 according to the invention. This has only one buckle element 5 and a different shape of the second regions. The areas A, B, C, D, E and F are areas in which sections of the awning overlap. In these areas, the different sections of the awning are sewn together.

Figur 7 zeigt die dritte Ausführungsform in einer Frontansicht. FIG. 7 shows the third embodiment in a front view.

Figur 8 zeigt die Abschnitte (Stoffzuschnitte) 27, 28, 29 aus denen das Sonnensegel der dritten Ausführungsform durch Nähen gebildet wird. Die mit A gekennzeichneten Bereiche überlappen beim dem fertigen Sonnensegel einander und sind miteinander vernäht. Ebenso verhält es sich mit den mit B, C, D, E und F gekennzeichneten Bereichen. FIG. 8 shows the sections (fabric blanks) 27, 28, 29 from which the awning of the third embodiment is formed by sewing. The areas marked with A overlap each other in the finished awning and are together sutured. The same applies to the areas marked B, C, D, E and F.

Die Figuren 9 und 10 zeigen eine erste Ausführungsform eines Knickprofils 50, welches als äußeres Wölbungselement 9 verwendet werden kann. Das Knickprofil besteht aus zwei geraden Schenkeln 22 und einem beide Schenkel 22 verbindenden Gelenk 21. In den einander zugewandten Fronflächen der Schenkel 22, welche geneigt ausgebildet sind, ist eine Fassung 23 für Magnete 24 angeordnet. Bei den Magneten 24 kann es sich um Neodym-Magnete handeln, welche sich aufgrund ihrer starken Magnetisierung besonders gut eigenen. Die Magnete 24 bewirken, dass die geknickte Form beibehalten wird, und das Knickprofil erst wieder seine gerade Form annimmt, wenn es sich beim Aufwickeln der Wickelwelle nähert, was durch die vorgenannten Federwinkel 30 unterstützt werden kann.The FIGS. 9 and 10 show a first embodiment of a buckling profile 50, which can be used as an outer bulging element 9. The buckling profile consists of two straight legs 22 and a joint 21 connecting both legs 22. A socket 23 for magnets 24 is arranged in the mutually facing front surfaces of the legs 22, which are inclined. The magnets 24 may be neodymium magnets, which are particularly well-suited due to their strong magnetization. The magnets 24 cause the kinked shape is maintained, and the buckling profile only returns to its straight shape when approaching the winding shaft during winding, which can be supported by the aforementioned spring angle 30.

Die Figuren 11 und 12 zeigen eine zweite Ausführungsform eines Knickprofils 60, welches als äußeres Wölbungselement 9 verwendet werden kann. Das Knickprofil 60 besteht aus zwei gewölbten Schenkeln 62 und einem beide Schenkel 62 verbindenden Gelenk 61.
