Definitions
- the invention relates to a covering device with a flexible, flat covering means, such as blinds, awning cloth or the like., Which is wound on a winding shaft and fastened with its free, front edge to an edge strip, which is arranged at both ends with two spaced apart , first and second rollers in lateral guide rails and held under spring action by at least one flexible traction means, which is deflected at the outer ends of the guide rails and is wound on winding rollers that sit on the winding shaft.
- a flexible, flat covering means such as blinds, awning cloth or the like.
- Flexible cover means such as awning covers or the like, serve as sun protection for patios and pergolas, but also as a cover for swimming pools to protect against dust, leaves and other contaminants.
- the fabric When removing the blind or the fabric from the winding shaft, the fabric must be held in the longitudinal and transverse directions, the transverse tension is effected with an edge strip in which the free, front edge of the fabric is clamped, while the longitudinal tension in two flexible traction means Take the form of ropes attached to the are attached to both ends of the edge strip and are returned via deflection rollers at the outer ends of the guide rail to the winding shaft, where they wind up on winding rollers when the awning fabric is unwound.
- the known covering devices have the disadvantage that they either have the length differences of the traction means do not compensate sufficiently or the awning fabric or the blinds cannot be led around arches, as is often the case with pergolas, where the cover material should not only protect against the incidence of light from above, but also against the incidence of light from the front.
- the side guide rails do not run in a straight line, but have a kink that must be traversed by the edge strip. It can easily happen that the traction means jump off their infeed rollers.
- the object of the invention is to provide a covering device of the type described in the introduction with simple means such that the covering means with its edge strip can also be advanced and pushed back along longitudinally bent or bent guide rails and at the same time large length differences of the traction means in the edge strip are compensated for, where the Traction devices are easily accessible and their tension can be easily adjusted.
- the traction means is introduced into the edge strip via infeed rollers arranged at the ends of the edge strip and is supported on guide rollers arranged transversely to the deflection rollers, the traction means grooves of which are tangentially aligned with the traction means grooves of the entry rollers.
- This configuration has the advantage that the traction means for tensioning the awning fabric in any angular position of the edge strip can safely run into it and also not jump off where the edge strip of the awning fabric passes through arches or angles in the lateral guide rails.
- the traction means are held under tension by springs, there can be large differences in length of the tension springs can be compensated for, which can be tensioned from the outside at the same time in a position that is easily accessible even when the awning is open.
- the guide rollers are arranged coaxially with the first rollers. These can be designed as twin rollers, between each of which a guide roller is arranged. As a result, the rollers also serve as lateral guides for the guide roller, which expediently has a smaller diameter than the rollers.
- the guide rollers and / or at least one of the rollers are axially displaceably mounted at the ends of the edge strip so that the edge strip can easily be crooked within certain limits when the covering means is pulled forward and pulled back.
- the guide rails expediently have lateral guide surfaces for the rollers, so that they are held laterally and are always pushed back into their guideways. It is expedient here if the first and the second rollers each have their own lateral guide surfaces in the guide rails.
- 10 denotes a covering device, namely a pergola awning, which can cover and shade a glazed porch 11 of a residential house (not shown) on its top 12 and on its front 13.
- the covering device 10 consists of a flexible, flat covering means 14, namely an awning cloth, which is wound on a winding shaft 15, which is mounted in the awning box 16.
- the covering means 14 is fastened to an edge strip 17 which is guided at its two ends 17a and 17b in lateral guide rails 18 and 19.
- Each guide rail 18 or 19 is supported with supports 20 on the stem 11 and consists of an upper, almost horizontal part 18a or 19a and a lower, approximately vertical part 18b or 19b. Where the upper and lower parts of the guide rails 18 and 19 meet, they are connected to one another by curved parts 18c and 19c.
- the traction means are wound on take-up rolls 22 which are attached to and rotate with the ends of the take-up shaft 15, the pulling means being directed onto the take-up roll 22 so that they wind up the pulling means while the covering means 14 is being unwound from the take-up shaft and vice versa.
- the traction means 21 run through the guide rails 18 and 19 to their free, lower ends 23 and 24, respectively. There they are deflected via deflection rollers 25 and 26 and returned through the guide rails to the edge strip 17, in which their ends are connected to a tension spring 27 are attached, which is located inside the edge strip 17.
- each guide rail 18 or 19 consists of a hollow profile carrier with two upper chambers 28 and 29, and two lower chambers 30 and 31, which are separated from one another by a lateral intermediate wall 32 and two intermediate floors 33 and 34 .
- the supports 20 are fixed, which carry the guide rails 18 and 19.
- the upper chamber which is located on the inside in each case, is open on its inside facing the awning fabric and receives the guide means for the edge strip 17.
- the traction means 21 is guided, which runs off the take-up roll 22 and, after being deflected around the deflecting roll 25 or 26, passes through a recess in the intermediate floor 33 into the upper chamber 29.
- the guide means 35 with which each of the two ends 17a and 17b of the edge strip 17 is guided in the guide rails 18 and 19, consist of first rollers 36 and second rollers 37, which are arranged at a distance from one another in the pull-out direction of the cover means 14.

- the first rollers 36 and the guide roller 39 are rotatably supported independently of one another on the same axis 41, which is mounted in the edge strip 17 to be displaceable to a limited extent in the axial direction. Both first rollers are guided on lateral guide surfaces 42 and 43 of the guide rails 18 and 19, respectively.
- the second roller 37 has a slightly larger diameter than the first rollers 36 and is guided on its own lateral guide surfaces 44 and 45 in the open, upper chamber 29. It is rotatable on a fixed axis 46 and axially displaceable.
- an inlet roller 47 which is arranged transversely to the rollers 36 and 37 and whose axis of rotation 48 is arranged approximately perpendicularly between the axes 41 and 46 of the rollers.
- the inlet roller 47 also has a cable groove 49 in which it deflects the traction means 21 coming from the deflection roller 25 or 26 into the interior of the edge strip.
- the traction means 21 is supported by the guide roller 39 in every position of the edge strip 17 in such a way that it runs exactly tangentially into the cable groove 49 of the inlet roller 47 and length compensation takes place inside the edge strip can if this passes through the arc parts 18 c or 19 c of the guide rails 18 and 19.
- the edge strip 17th can skew within certain limits when pulling out or retracting without constraints in the guide means 35, since the first and second rollers 36 and 37 can move together with the guide roller 39 mounted between the first rollers in the axial direction.
- the rollers 36 and 37 are provided with chamfers 50 and 51 on their outer peripheral edges.
- the length compensation of the traction means inside the edge strip can also be designed somewhat differently and it is also possible to store the guide rollers separately on the edge strip.

Abstract
Description
Die Erfindung betrifft eine Abdeckvorrichtung mit einem flexiblen, flächigen Abdeckmittel, wie Jalousie, Markisentuch oder dgl., das auf einer Aufwickelwelle aufgewickelt und mit seinem freien, vorderen Rand an einer Randleiste befestigt ist, die an ihren beiden Enden mit je zwei im Abstand voneinander angeordneten, ersten und zweiten Laufrollen in seitlichen Führungsschienen geführt und unter Federwirkung von mindestens einem flexiblen Zugmittel gespannt gehalten wird, das an den äußeren Enden der Führungsschienen umgelenkt wird und auf Aufwickelrollen aufgewickelt ist, die auf der Aufwickelwelle sitzen.The invention relates to a covering device with a flexible, flat covering means, such as blinds, awning cloth or the like., Which is wound on a winding shaft and fastened with its free, front edge to an edge strip, which is arranged at both ends with two spaced apart , first and second rollers in lateral guide rails and held under spring action by at least one flexible traction means, which is deflected at the outer ends of the guide rails and is wound on winding rollers that sit on the winding shaft.
Flexible Abdeckmittel, wie Markisentücher oder dgl., dienen als Sonnenschutz für Terassen und Pergolen, aber auch als Abdeckung für Schwimmbecken zum Schutz vor Staub, Laub und anderen Verunreinigungen. Beim Abziehen der Jalousie oder des Tuches von der Aufwickelwelle muß das Tuch in Längs- und Querrichtung gespannt gehalten werden, wobei die Querspannung mit einer Randleiste bewirkt wird, in der der freie, vordere Rand des Tuches eingespannt ist, während die Längsspannung zwei flexible Zugmittel in Form von Seilen übernehmen, die an den beiden Enden der Randleiste befestigt sind und über Umlenkrollen an den äußeren Enden der Führungsschiene zur Aufwickelwelle zurückgeführt werden, wo sie sich beim Abwickeln des Markisentuches auf Aufwickelrollen aufwickeln. Längenänderungen der Zugmittel, die beim Auf- und Abrollen des Markisentuches mit dem gleichzeitigen Abwickeln und Aufwickeln der Zugmittel auftreten, werden durch Federelemente ausgeglichen, die in den Führungsschienen oder in der vorderen Randleiste angeordnet werden können.
Es ist bekannt (DE 35 20 857 A1), die Enden der Randleiste mit Rollenwagen zu führen, die je zwei im Abstand voneinander angeordnete erste und zweite Laufrollen haben. An jedem Rollenwagen ist ein flexibles Zugmittel befestigt und ein Ende der Randleiste gelagert, die eine Torsionsfeder enthält, die bestrebt ist, die Randleiste so zu drehen, daß der Tuchrand auf ihr aufgewickelt wird und das Markisentuch hierdurch gespannt wird. Hierbei dienen die Rollenwagen der Torsionsfeder als Widerlager und nehmen das Torsionsmoment auf, indem die im Abstand voneinander angeordneten Laufrollen ein dem Moment entsprechendes Kräftepaar auf die Führungsschiene übertragen.Flexible cover means, such as awning covers or the like, serve as sun protection for patios and pergolas, but also as a cover for swimming pools to protect against dust, leaves and other contaminants. When removing the blind or the fabric from the winding shaft, the fabric must be held in the longitudinal and transverse directions, the transverse tension is effected with an edge strip in which the free, front edge of the fabric is clamped, while the longitudinal tension in two flexible traction means Take the form of ropes attached to the are attached to both ends of the edge strip and are returned via deflection rollers at the outer ends of the guide rail to the winding shaft, where they wind up on winding rollers when the awning fabric is unwound. Changes in length of the traction means, which occur when the awning fabric is rolled up and down with the simultaneous unwinding and winding up of the traction means, are compensated for by spring elements which can be arranged in the guide rails or in the front edge strip.
It is known (
Um eine einfachere Konstruktion zu erreichen und auch größere Längenänderungen der Zugmittel federnd aufnehmen zu können, ist es auch bekannt, die Enden der Zugmittel über Einlaufrollen in die Randleiste einzuführen und dort unter Zwischenschaltung einer Feder in der Randleiste zu verankern (Eu 0 207 040 B1). Bei schmalen und langen Markisen und Pergolen können die Enden der Zugmittel auch ein- oder mehrfach über Rollen geschoren sein.In order to achieve a simpler construction and to be able to absorb larger changes in length of the traction means, it is also known to insert the ends of the traction means into the edge strip via infeed rollers and to anchor them there with the interposition of a spring in the edge strip (Eu 0 207 040 B1) . In the case of narrow and long awnings and pergolas, the ends of the traction means can also be shaved one or more times over rollers.
Die bekannten Abdeckvorrichtungen haben den Nachteil, daß sie entweder die Längendifferenzen der Zugmittel nicht ausreichend kompensieren oder das Markisentuch oder die Jalousie kann nicht um Bögen geführt werden, wie dies bei Pergolen häufig der Fall ist, bei denen das Abdeckmittel nicht nur gegen Lichteinfall von oben, sondern auch gegen Lichteinfall von der Vorderseite her schützen soll. Bei diesen Pergolen verlaufen die seitlichen Führungsschienen nicht geradlinig, sondern haben einen Knick, der von der Randleiste durchfahren werden muß. Hierbei kann es leicht geschehen, daß die Zugmittel von ihren Einlaufrollen abspringen.The known covering devices have the disadvantage that they either have the length differences of the traction means do not compensate sufficiently or the awning fabric or the blinds cannot be led around arches, as is often the case with pergolas, where the cover material should not only protect against the incidence of light from above, but also against the incidence of light from the front. In these pergolas, the side guide rails do not run in a straight line, but have a kink that must be traversed by the edge strip. It can easily happen that the traction means jump off their infeed rollers.
Aufgabe der Erfindung ist es, eine Abdeckvorrichtung der eingangs näher erläuterten Art mit einfachen Mitteln so auszubilden, daß das Abdeckmittel mit seiner Randleiste auch längs gebogener oder geknickter Führungsschienen vorgezogen und zurückgeschoben werden kann und gleichzeitig große Längendifferenzen der Zugmittel in der Randleiste kompensiert werden, wo die Zugmittel leicht zugänglich sind und ihre Spannung leicht eingestellt werden kann.The object of the invention is to provide a covering device of the type described in the introduction with simple means such that the covering means with its edge strip can also be advanced and pushed back along longitudinally bent or bent guide rails and at the same time large length differences of the traction means in the edge strip are compensated for, where the Traction devices are easily accessible and their tension can be easily adjusted.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, daß das Zugmittel über an den Enden der Randleiste angeordnete Einlaufrollen in die Randleiste eingeführt und auf quer zu den Einlenkrollen angeordneten Führungsrollen abgestützt ist, deren Zugmittelrillen tangential mit den Zugmittelrillen der Einlaufrollen fluchten.This object is achieved with the invention in that the traction means is introduced into the edge strip via infeed rollers arranged at the ends of the edge strip and is supported on guide rollers arranged transversely to the deflection rollers, the traction means grooves of which are tangentially aligned with the traction means grooves of the entry rollers.
Diese Ausgestaltung hat den Vorteil, daß die Zugmittel zum Spannen des Markisentuches in jeder beliebigen Winkellage der Randleiste in diese sicher einlaufen können und auch dort nicht abspringen, wo die Randleiste des Markisentuches Bögen oder Winkel in den seitlichen Führungsschienen durchläuft. In der Randleiste, wo die Zugmittel von Federn gespannt gehalten werden, können große Längendifferenzen der Zugfedern kompensiert werden, die dort gleichzeitig von außen an einer Stelle gespannt werden können, die auch im aufgespannten Zustand der Markise leicht zugänglich ist.This configuration has the advantage that the traction means for tensioning the awning fabric in any angular position of the edge strip can safely run into it and also not jump off where the edge strip of the awning fabric passes through arches or angles in the lateral guide rails. In the sidebar, where the traction means are held under tension by springs, there can be large differences in length of the tension springs can be compensated for, which can be tensioned from the outside at the same time in a position that is easily accessible even when the awning is open.
Besonders zweckmäßig ist es wenn die Führungsrollen koaxial zu den ersten Laufrollen angeordnet sind. Diese können als Zwillingsrollen ausgebildet sein, zwischen denen je eine Führungsrolle angeordnet ist. Die Laufrollen dienen hierdurch zugleich als Seitenführung für die Führungsrolle, die zweckmäßig einen kleineren Durchmesser hat als die Laufrollen.It is particularly expedient if the guide rollers are arranged coaxially with the first rollers. These can be designed as twin rollers, between each of which a guide roller is arranged. As a result, the rollers also serve as lateral guides for the guide roller, which expediently has a smaller diameter than the rollers.
Damit sich die Randleiste beim Vorziehen und Zurückziehen des Abdeckmittels innerhalb gewisser Grenzen zwanglos schiefstellen kann, sind die Führungsrollen und/oder mindestens eine der Laufrollen an den Enden der Randleiste axial verschieblich gelagert. Ferner weisen die Führungsschienen zweckmäßig seitliche Führungsflächen für die Laufrollen auf, so daß diese seitlich gehalten sind und immer wieder in ihre Führungsbahnen zurückgedrängt werden. Hierbei ist es zweckmäßig, wenn die ersten und die zweiten Laufrollen jeweils eigene, seitliche Führungsflächen in den Führungsschienen haben.The guide rollers and / or at least one of the rollers are axially displaceably mounted at the ends of the edge strip so that the edge strip can easily be crooked within certain limits when the covering means is pulled forward and pulled back. Furthermore, the guide rails expediently have lateral guide surfaces for the rollers, so that they are held laterally and are always pushed back into their guideways. It is expedient here if the first and the second rollers each have their own lateral guide surfaces in the guide rails.

In den Zeichnungen ist mit 10 eine Abdeckvorrichtung, nämlich eine Pergola-Markise bezeichnet, die einen verglasten Vorbau 11 eines nicht näher dargestellten Wohnhauses auf seiner Oberseite 12 und an seiner Vorderseite 13 abdecken und beschatten kann. Die Abdeckvorrichtung 10 besteht aus einem flexiblen, flächigen Abdeckmittel 14, nämlich einem Markisentuch, das auf einer Aufwickelwelle 15 aufgewickelt ist, die im Markisenkasten 16 gelagert ist. An seinem freien, vorderen Rand ist das Abdeckmittel 14 an einer Randleiste 17 befestigt, die an ihren beiden Enden 17a und 17b in seitlichen Führungsschienen 18 und 19 geführt ist.In the drawings, 10 denotes a covering device, namely a pergola awning, which can cover and shade a
Jede Führungsschiene 18 bzw. 19 ist mit Stützen 20 am Vorbau 11 abgestützt und besteht mit aus einem oberen, nahezu waagerechten Teil 18a bzw.19a und aus einem unteren, annähernd vertikalen Teil 18b bzw. 19b . Dort, wo die oberen und unteren Teile der Führungsschienen 18 und 19 zusammenstoßen, sind sie durch Bogenteile 18c bzw. 19c miteinander verbunden.Each
Beim Abwickeln und Vorziehen des flexiblen Abdeckmittels 14 wird dieses in Längsrichtung von einem Zugmittel 21, nämlich von einem dünnen Kunststoffseil 21, gespannt gehalten, das seitlich neben den Seitenrändern 14 angeordnet ist und im Inneren der Randleiste 17 verläuft.When unwinding and pulling forward the flexible covering means 14, this is held tensioned in the longitudinal direction by a traction means 21, namely by a thin
Die Zugmittel sind auf Aufwickelrollen 22 aufgewickelt, die an den Enden der Aufwickelwelle 15 befestigt sind und sich mit dieser drehen, wobei die Zugmittel so auf die Aufwickelrolle 22 geleitet werden, daß diese die Zugmittel aufwickeln, während das Abdeckmittel 14 von der Aufwickelwelle abgewickelt wird und umgekehrt.The traction means are wound on take-
Die Zugmittel 21 laufen durch die Führungsschienen 18 bzw. 19 bis zu deren freien, unteren Enden 23 bzw. 24. Dort werden sie über Umlenkrollen 25 und 26 umgelenkt und durch die Führungsschienen bis zur Randleiste 17 zurückgeführt, in der ihre Enden an einer Zugfeder 27 befestigt sind, die sich im Inneren der Randleiste 17 befindet.The traction means 21 run through the
Wie aus Fig. 3 hervorgeht, besteht jede Führungsschiene 18 bzw. 19 aus einem hohlen Profilträger mit zwei oberen Kammern 28 und 29, und zwei unteren Kammern 30 und 31, die durch eine seitliche Zwischenwand 32 bzw. zwei Zwischenböden 33 und 34 voneinander getrennt sind. In der unteren Kammer 31 sind die Stützen 20 befestigt, welche die Führungsschienen 18 und 19 tragen. Die jeweils innen liegende obere Kammer ist an ihrer dem Markisentuch zugewandten Innenseite offen und nimmt die Führungsmittel für die Randleiste 17 auf. In der darunterliegenden, unteren Kammer 30 ist das Zugmittel 21 geführt, das von der Aufwickelrolle 22 abläuft und nach seiner Umlenkung um die Umlenkrolle 25 bzw. 26 durch eine Ausnehmung im Zwischenboden 33 in die obere Kammer 29 übertritt.As can be seen from FIG. 3, each
Die Führungsmittel 35, mit denen jedes der beiden Enden 17a und 17b der Randleiste 17 in den Führungsschienen 18 bzw. 19 geführt ist, bestehen aus ersten Laufrollen 36 und zweiten Laufrollen 37, die in Auszugrichtung des Abdeckmittels 14 im Abstand voneinander angeordnet sind.The guide means 35, with which each of the two
Die erste Laufrolle 36 ist als Zwillingsrolle ausgebildet und zwischen den Einzelrollen 36 a und 36 b ist eine Führungsrolle 39 angeordnet, die einen kleineren Durchmesser hat als die ersten Laufrollen 36 und eine Seilrille 40 aufweist. Die ersten Laufrollen 36 und die Führungsrolle 39 sind unabhängig voneinander drehbar auf der gleichen Achse 41 gelagert, die in der Randleiste 17 in Axialrichtung begrenzt verschieblich gelagert ist. Beide erste Laufrollen sind an seitlichen Führungsflächen 42 und 43 der Führungsschiene 18 bzw. 19 geführt.The
Die zweite Laufrolle 37 hat einen etwas größeren Durchmesser als die ersten Laufrollen 36 und ist an eigenen seitlichen Führungsflächen 44 und 45 in der offenen, oberen Kammer 29 geführt. Sie ist auf einer festen Achse 46 drehbar und axial verschieblich gelagert.The
Zwischen den ersten und zweiten Laufrollen 36 und 37 befindet sich eine Einlaufrolle 47, die quer zu den Laufrollen 36 und 37 angeordnet ist und deren Drehachse 48 annähernd senkrecht zwischen den Achsen 41 und 46 der Laufrollen angeordnet ist. Die Einlaufrolle 47 hat ebenfalls eine Seilrille 49, in der sie das von der Umlenkrolle 25 bzw. 26 kommende Zugmittel 21 ins Innere der Randleiste umlenkt.Between the first and
Man erkennt insbesondere aus den Figuren 2 und 3, daß das Zugmittel 21 von der Führungsrolle 39 in jeder Lage der Randleiste 17 so abgestützt wird, daß es genau tangential in die Seilrille 49 der Einlaufrolle 47 einläuft und ein Längenausgleich im Inneren der Randleiste auch dann stattfinden kann, wenn diese die Bogenteile 18 c bzw. 19 c der Führungsschiene 18 und 19 durchläuft. Ferner erkennt man, daß die Randleiste 17 sich innerhalb gewisser Grenzen beim Ausziehen oder Einfahren schiefstellen kann, ohne daß Zwängungen in den Führungsmitteln 35 auftreten, da sich die ersten und zweiten Laufrollen 36 und 37 zusammen mit der zwischen den ersten Laufrollen gelagerten Führungsrolle 39 in Axialrichtung verschieben können. Um Zwängungen zu vermeiden, sind die Laufrollen 36 und 37 an ihren äußeren Umfangsrändern mit Abfasungen 50 bzw. 51 versehen.It can be seen in particular from FIGS. 2 and 3 that the traction means 21 is supported by the
Die Erfindung ist nicht auf die dargestellte und beschriebene Ausführungsform beschränkt, sondern es sind mehrere Änderungen und Ergänzungen möglich, ohne den Rahmen der Erfindung, wie sie in den Ansprüchen definiert ist, zu verlassen. Beispielsweise kann der Längenausgleich des Zugmittels im Inneren der Randleiste auch etwas anders ausgebildet sein und es ist auch möglich, die Führungsrollen separat an der Randleiste zu lagern. Es ist möglich, die Laufrollen etwas anders auszubilden oder anstelle eines Seiles eine dünne Kette oder ein Stahlseil zu verwenden.The invention is not limited to the illustrated and described embodiment, but several changes and additions are possible without leaving the scope of the invention as defined in the claims. For example, the length compensation of the traction means inside the edge strip can also be designed somewhat differently and it is also possible to store the guide rollers separately on the edge strip. It is possible to design the rollers a little differently or to use a thin chain or a steel cable instead of a rope.
