Abstract
Description
Die Erfindung betrifft eine Spannvorrichtung für ein flexibles, flächiges Abdeckmittel, wie Jalousie, Markisentuch od.dgl., das mit einer hohlen Randleiste an Führungsschienen geführt und von einem flexiblen Zugmittel gespannt gehalten wird, das mit seinen hinteren Enden auf Aufwickelrollen aufgewickelt ist und das über Einlenkmittel in die Randleiste geführt und dort von mindestens einem Federmittel gespannt gehalten wird, das an in Wirkrichtung des Federmittels frei beweglichen Umlenkrollen für das Zugmittel befestigt ist.The invention relates to a tensioning device for a flexible, flat covering means, such as blinds, awning cloth or the like, which with a hollow edge ledge on guide rails and by a flexible traction device is kept under tension with its rear ends wound on take-up reels is and that by means of steering means in the sidebar guided and there by at least one spring means is kept tense, the in the direction of action of Spring freely movable pulleys for the traction device is attached.
Es ist eine Spannvorrichtung dieser Art bekannt (EP-A-0 207 040), bei der die vorderen Enden des Zugmittels in der Randleiste befestigt und um Umlenkrollen geführt sind, die an den Enden einer Zugfeder befestigt sind. Bei dieser bekannten Vorrichtung steht das Zugmittel auch bei der Montage ständig unter Federspannung, was die Montage erschwert und die Gefahr von Unfällen in sich birgt.A tensioning device of this type is known (EP-A-0 207 040), with the front ends of the traction device in the edge strip attached and guided around pulleys attached to the Ends of a tension spring are attached. In this known device the traction device is constantly under during assembly Spring tension, which makes assembly difficult and the risk of accidents contains in itself.
Aufgabe der Erfindung ist es, eine Spannvorrichtung der eingangs genannten Art zu verbessern und derart weiter auszugestalten, daß das Zugmittel ohne Federspannung leicht montiert werden kann und das Federmittel auch bei eingefahrenem, aufgerollten Abdeckmittel in seiner Federspannung leicht verändert werden kann.The object of the invention is to provide a clamping device at the beginning to improve and refine the type mentioned, that the traction device can be easily assembled without spring tension and the spring means even when the cover means is retracted and rolled up can be easily changed in its spring tension.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, daß die Einlenkmittel an der Randleiste angeordnet sind und daß das Zugmittel im Inneren der Randleiste über mindestens eine Montagespannrolle geführt ist, die in Längsrichtung der Randleiste verstellbar und an dieser feststellbar ist und daß das Federmittel mit seinem einen Ende an einem in Wirkrichtung des Federmittels verstellbaren Ankermittel befestigt ist.This object is achieved with the invention in that the steering means are arranged on the sidebar and that the traction device inside the sidebar guided over at least one assembly tension roller which is adjustable in the longitudinal direction of the sidebar at this can be determined and that the spring means with one end at one in the effective direction of the spring means adjustable anchor means attached is.
Diese Ausgestaltung hat den Vorteil, daß die Vor- und Endmontage der Spannvorrichtung sehr einfach ist, da das Zugmittel ohne Federspannung eingefädelt und an den Aufwickelrollen befestigt werden kann. Das Zugmittel wird erst nach dem Einlegen gespannt, wobei die normale Federspannung durch ein, vorzugsweise mittels eines Getriebes von außerhalb der Randleiste, verstellbares Ankermittel erzeugt wird, welches an mindestens ein Federmittel angeschlossen ist.This configuration has the advantage that the pre- and final assembly the tensioning device is very simple because the traction means without spring tension threaded and attached to the take-up reels can be. The traction device is only tensioned after insertion, the normal spring tension by a, preferably by means of a gear from outside Sidebar, adjustable anchor means is generated, which at least one spring means is connected.
Besonders zweckmäßig ist es, wenn im Inneren der Randleiste zwei Montagerollen vorgesehen sind, um welche das Zugmittel umgelenkt ist und die in ihrem gegenseitigen Abstand in Längsrichtung der Randleiste verstellbar und an der Randleiste feststellbar sind. Die beiden Montagespannrollen dienen gleichzeitig als Umlenkrollen, um den Längenausgleich des Zugmittels zusammen mit den an den Federn angeordneten Umlenkrollen nach Art eines vierfachen Rollenzuges zu verlängern. Hierbei können im Inneren der hohlen Randleiste zwei bewegliche Umlenkrollen und zwei Federmittel angeordnet sind. Durch die hierbei erreichte doppelte Umlenkung des Zugmittels, das im Inneren der Randleiste nicht befestigt wird, steht für den Längenausgleich praktisch der vierfache Weg zur Verfügung, wobei es die zwei Federn ermöglichen, die Spannung des Zugmittels auch bei größeren Längenänderungen immer etwa auf der gleichen Höhe zu halten.It is particularly useful if two inside the sidebar Assembly rollers are provided, around which the traction device is deflected is and in their mutual distance in the longitudinal direction of the Sidebar are adjustable and lockable on the sidebar. The two mounting idlers also serve as pulleys, around the length compensation of the traction device together with the the springs arranged deflection rollers in the manner of a fourfold Extend the roller train. This can inside the hollow Sidebar arranged two movable pulleys and two spring means are. Through the double redirection achieved here of the traction device, which is not fastened inside the edge strip is the fourfold way for length compensation available, the two springs allow the tension of the traction device always with larger length changes to keep at about the same height.
Eine besonders einfache Konstruktion ergibt sich, wenn die Montagespannrollen mit ihren Drehachsen in Gleitsteinen sitzen, die in einer C-förmigen Spannschiene gegeneinander verschiebbar und mit Stehbolzen und Klemmuttern festsetzbar sind. A particularly simple construction results when the mounting idlers sit with their axes of rotation in sliding blocks that Slidable against each other in a C-shaped tensioning rail can be fixed with stud bolts and locknuts.

hohlen Randleiste 14 befestigt ist. Die beiden Seitenränder
18 und 19 der Markise 12 und die beiden Enden 14a und 14b der
Randleiste 14 werden in seitlichen Führungsschienen geführt,
wie dies in DE-A-40 36 892 näher erläutert, hier aber nicht
näher dargestellt ist. In the drawings, 10 denotes a covering device,
which is a flexible, flat covering means 12, namely
has an awning fabric that is unwound from a
Das Markisentuch 12 wird von einer Spannvorrichtung gespannt
gehalten, die im Inneren 14c der Randleiste 14 angeordnet
und in ihrer Gesamtheit mit 15 bezeichnet ist. Die Spannvorrichtung
15 hält ein flexibles Zugmittel 20 gespannt, das
von einem dünnen Textilseil gebildet wird und deren
beide Enden auf je einer Aufwickelrolle 26 auf- oder abgewickelt
werden. Die Aufwickelrollen 26 sind an beiden Enden
der Wickelwelle 13 angeordnet und mit dieser fest verbunden.
Vor den Aufwickelrollen 26 befinden sich Leitrollen 45, welche
das Zugmittel 20 auf die Aufwickelrollen 26 leiten.The
Das von den Aufwickelrollen 26 abgewickelte Zugmittel wird
zunächst um äußere Umlenkrollen 24 geführt, die sich an den
vorderen Enden der Führungsschienen befinden, wie dies in
DE-A-40 36 892 näher erläutert ist. Diese äußeren Umlenkrollen
24 sind in Fig. 1 nur schematisch angedeutet. Von den äußeren
Umlenkrollen 24 läuft das Zugmittel dann in den nicht
dargestellten Führungsschienen zur Randleiste 14 zurück, in
die es über Einlenkmittel 46 ins Innere 14c der hohlen Randleiste
14 eingeleitet wird. Diese Einlenkmittel 46 sind bei
dem dargestellten Ausführungsbeispiel Einlenkrollen, die
etwa parallel zur Markisentuchebene angeordnet sind. Anstelle
dieser Rollen können aber auch Gleitschienen vorgesehen
sein.The traction means unwound from the take-
Im Inneren 14c der Randleiste 14 läuft das Zugmittel 20 zunächst
über eine Montagespannrolle 47a, wo es umgelenkt
wird und zu der rechten Spannrolle 34a gelangt. Dort wird
das Zugmittel wiederum um 180° umgelenkt und gelangt zur
linken Spannrolle 34b, wo es umgelenkt und zu der linken
Montagespannrolle 47b geführt wird, von wo aus es wieder
zu der linken Einlenkrolle 46 geführt wird.The traction means 20 initially runs in the
Die beiden Spannrollen 34a und 34b sind frei beweglich an
den äußeren Enden der Federmittel 36a und 36b befestigt,
von denen das rechte Federmittel 36a am Stirnende der Randleiste
14 festgelegt ist. Das hintere Ende des linken Federmittels
36b jedoch ist in einem Ankermittel 32, nämlich einem
in der Randleiste 14 gleitend gelagerten Ankerblock verankert.
Der Ankerblock 32 hat eine sich in dessen Längsrichtung erstreckende
Bohrung 39, die von einer langgestreckten Gewindespindel
40 durchsetzt wird. Das linke, äußere Ende der Gewindespindel
40 ist in einem Widerlagerblock 30 gelagert, der am
linken Stirnende der Randleiste 14 befestigt ist und ein Winkelgetriebe
beherbergt, mit dem die Gewindespindel 40 von
außerhalb der Randleiste 14 gedreht werden kann.The two
Man erkennt, daß das linke Federmittel 36b, das im dargestellten
Ausführungsbeispiel eine Zugfeder ist, gespannt wird, wenn
der Ankerblock 32 durch Drehen der Gewindespindel 40 in Richtung
des Pfeiles 48 nach links gezogen wird. Die auf das Zugmittel
20 über die Spannrollen 34b und 34a ausgeübte Spannkraft
wird dann vergrößert.It can be seen that the left spring means 36b, that in the illustrated
Embodiment is a tension spring, is tensioned when

Wie aus Fig. 3 hervorgeht, sind die beiden Montagespannrollen 47a
und 47b mit ihren vertikalen Drehachsen 49 in einer C-förmigen
Spannschiene 50 in ihrem gegenseitigen Abstand a verstellbar
befestigt. Zu diesem Zweck sitzt jede Drehachse in einem
Gleitstein 51, der an seiner Unterseite mit einem Stehbolzen
52 versehen ist. Der Stehbolzen 52 durchgreift einen Schlitz
53 im Steg 54 der Spannschiene 50. Auf den Stehbolzen 52 ist
eine Klemmutter 55 aufgeschraubt, mit der der Gleitstein 51
in der C-förmigen Spannschiene 50 festgesetzt werden kann.3, the two
Beim Einfädeln des Zugmittels 20 in die Randleiste 14 sitzen
die Montagespannrollen 47a und 47b zunächst lose im Schlitz
53. Nach dem Befestigen der Enden des Zugmittels 20 an den
Aufwickelrollen 26 werden dann die beiden Montagespannrollen
47a und 47b gegeneinander geschoben, so daß sich der gegenseitige
Abstand a verkleinert und die Zugfedern 36a und 36b
gespannt werden. Dann werden die Montagespannrollen 47 mit
Hilfe der Klemmuttern 55 festgesetzt. Die Spannung der Zugfedern
36a und 36b kann dann mit Hilfe der Spannvorrichtung
15 genau eingestellt und auch während des Betriebes noch
verstellt werden. Hierzu wird ein Werkzeug in das Winkelgetriebe
im Widerlagerblock 30 eingeführt und die Spindelmutter

Die Erfindung ist nicht auf das dargestellte und beschriebene
Ausführungsbeispiel beschränkt, sondern es sind Änderungen
und Ergänzungen möglich, ohne den Rahmen der Erfindung zu verlassen.
Beispielsweise könnte das Zugmittel auch noch um mehrere
Rollen geschoren sein, wenn bei sehr langen Markisen
oder Jalousien größere Wegdifferenzen im Zugmittel auftreten.
Ferner könnte eine Spannvorrichtung 15 auch an dem zweiten
