Description

Die Erfindung bezieht sich auf einen Faltvorhang, insbesondere für Wintergärten, mit mehreren, den Vorhang in vorgesehenen, im Abstand voneinander liegenden Aufnahmen durchquerenden Spanndrähten, deren Enden in einer Spannwelle bzw. einer Unterschiene des Vorhangs befestigt sind und die, um ein Durchhängen des Vorhanges zu verhindern, über eine an der Kopfschiene gehalterte Vorrichtung spannbar sind. Bei bekannten Ausführungsformen wird als Spannvorrichtung eine Schneckengetriebe verwendet, dessen Gehäuse an der Kopfschiene befestigt werden muß. Diese Bauweise ist nicht nur kostenintensiv, sondern sie hat auch den Nachteil, daß die einzelnen Bestandteile wie Schnecke, Lagerböcke, Schneckenrad, Spannwelle sowie die Befestigungsglieder nicht raumsparend untergebracht werden können. Der Einbau der Spannvorrichtung ist deshalb innerhalb der Kopfschiene nicht möglich.The invention relates to a folding curtain, in particular for conservatories, with a plurality of tensioning wires, the ends of which are fastened in a tensioning shaft or a bottom rail of the curtain, and which are used to prevent the curtain from sagging prevent can be clamped via a device held on the headrail. In known embodiments, a worm gear is used as the clamping device, the housing of which has to be fastened to the head rail. This construction is not only cost-intensive, but it also has the disadvantage that the individual components such as worm, bearing blocks, worm wheel, tension shaft and the fastening elements cannot be accommodated in a space-saving manner. It is therefore not possible to install the tensioning device within the head rail.

Der Erfindung liegt die Aufgabe zugrunde, eine Spannvorrichtung für Faltvorhänge zu schaffen, die sich preisgünstig herstellen und in der Kopfschiene unterbringen läßt. Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß als Spannvorrichtung eine Welle dient, deren Enden von Lagerbohrungen aufgenommen sind, die in den Schenkein der U-förmigen Kopfschiene sitzen, wobei die Spannwelle, auf deren Mantel der Spanndraht aufwickelbar ist, mit Hilfe eines Werkzeugs derart drehbar ist, daß der Spanndraht sich strafft, wobei die Drehbewegung der Spannwelle durch eine Schraubenmutter, die mit einem Außengewinde des einen als Achsstumpf ausgebildeten Endes der Welle zusammenwirkt, feststellbar ist, und der die Schraubenmutter aufnehmende Achsstumpf in die als Hohlkörper ausgebildete Spannwelle bereichsweise eingepreßt ist. Durch diese Ausbildung wird erreicht, daß die Spannwelle die gesamte Spannvorrichtung ersetzt. Dieses läßt sich zum einen leicht und kostengünstig durchführen, wobei die Handhabung der Spannwelle auch für Laien besonders einfach ist, und zum anderen ist diese Bauweise auch aus fertigungstechnischen Gründen empfehlenswert.The invention has for its object to provide a tensioning device for folding curtains, which are inexpensive to manufacture and accommodate in the head rail leaves. To achieve this object, it is proposed according to the invention that a shaft serves as the clamping device, the ends of which are received by bearing bores which are seated in the legs of the U-shaped head rail, the clamping shaft, on the jacket of which the tensioning wire can be wound, with the aid of a tool in such a way It is rotatable that the tensioning wire tightens, the rotational movement of the tensioning shaft being detectable by a screw nut which cooperates with an external thread of the one end of the shaft designed as an axle stub, and the axle stub receiving the screw nut is pressed in regions into the tensioning shaft designed as a hollow body . This configuration ensures that the tensioning shaft replaces the entire tensioning device. On the one hand, this can be carried out easily and inexpensively, the handling of the tensioning shaft being particularly simple even for laypeople, and on the other hand, this construction is also recommended for production reasons.

Bei einer bevorzugten Ausführungsform der Erfindung kann als Werkzeug ein Stiftschlüssel verwendet werden, der mit einer im Kopf des Achsstumpfes vorgesehenen Mehrkant-Aufnahme zusammenwirkt. Dieses hat den Vorteil, daß sich die Spannwelle mit einem handelsüblichen Werkzeug, welches überall zur Verfügung steht, einstellen läßt.In a preferred embodiment of the invention, a pin wrench can be used as the tool, which interacts with a polygonal receptacle provided in the head of the stub axle. This has the advantage that the tensioning shaft can be adjusted using a commercially available tool that is available everywhere.

Es ist aber auch möglich, als Werkzeug formschlüssige Glieder, wie Knebel, Flügelmuttern, Flügelschrauben od.dgl. einzusetzen, die mit der Spannwelle in Wirkverbindung stehen und manuell betätigbar sind.However, it is also possible to use form-fitting members such as gags, wing nuts, wing screws or the like as a tool. use that in operative connection with the tension shaft stand and can be operated manually.

Die Fig. 1 zeigt einen Ausschnitt eines Wintergartens mit einem Fenster 10, das mit einem Faltvorhang 11 ausgerüstet werden soll. In der Fig. 1 ist veranschaulicht, wie die Befestigung des Faltvorhanges 11 erfolgen soll. Der Faltvorhang 11 wird von Spanndrähten 12 durchquert, die nacheinander durch Aufnahmen geführt werden, welche in dem Vorhang 11 im Abstand voneinander vorgesehen sind. Diese Spanndrähte 12 verhindern ein Durchhängen des Faltvorhanges 11. Ihre Enden werden in der Spannwelle 15 und in der Unterschiene 14 befestigt. Das Straffen der Spanndrähte 12 erfolgt mit Hilfe der Spannwelle 15, welche in den Fig. 2 und 4 wiedergegeben ist. Wie die Fig. 2 veranschaulicht, weist die Spannwelle 15 Enden 16 auf, die in Lagerbohrungen 17 der Kopfschiene 13 Aufnahme finden. Das obere Ende 18 des Spanndrahtes 12 wird, wie aus der Fig. 2 ersichtlich, durch eine Bohrung 19 hindurchgeführt, die sich im Mantel der Spannwelle 15 befindet. Sobald dieses erfolgt ist, wird die Spannwelle 15, wie Fig. 2 zeigt, mit Hilfe eines Stiftschlüssels 20 gedreht, so daß sich der Spanndraht 12 auf dem Mantel der Spannwelle 15 aufwickelt. Die Drehbewegung des Stiftschlüssels 20 wird beendet, sobald der Spanndraht 12 die erforderliche Spannung aufweist.Fig. 1 shows a section of a winter garden with a window 10, which is to be equipped with a folding curtain 11. 1 illustrates how the folding curtain 11 is to be attached. The folding curtain 11 is traversed by tension wires 12 which are successively guided through receptacles which are provided in the curtain 11 at a distance from one another. These tensioning wires 12 prevent the folding curtain 11 from sagging. Their ends are fastened in the tensioning shaft 15 and in the lower rail 14. The tensioning wires 12 are tightened with the aid of the tensioning shaft 15, which is shown in FIGS. 2 and 4. As illustrated in FIG. 2, the tensioning shaft 15 has ends 16 which are received in bearing bores 17 of the head rail 13. As can be seen from FIG. 2, the upper end 18 of the tensioning wire 12 is passed through a bore 19 which is located in the jacket of the tensioning shaft 15. As soon as this has taken place, the tensioning shaft 15, as shown in FIG. 2, is rotated with the aid of a spanner 20, so that the tensioning wire 12 is on the jacket of the tensioning shaft 15 wound up. The rotary movement of the pin key 20 is terminated as soon as the tensioning wire 12 has the required tension.

Aus der Fig. 2 geht hervor, daß das vordere Ende 16 als Achsstumpf ausgebildet ist und mit einem Außengewinde 21 versehen ist, welches eine Schraubenmutter 22 aufnimmt. Diese wird mit einem Schraubenschlüssel 23 angezogen, sobald das Spannen des Spanndrahtes 12 beendet ist. Das hintere Ende 16 ist nicht abgesetzt, sondern weist den gleichen Durchmesser wie die Spannwelle 15 auf.From Fig. 2 it can be seen that the front end 16 is formed as a stub axle and is provided with an external thread 21 which receives a nut 22. This is tightened with a wrench 23 as soon as the tensioning of the tensioning wire 12 has ended. The rear end 16 is not offset, but has the same diameter as the tension shaft 15.

An den oberen und unteren Rändern des Fensters 10 sind, wie Fig. 1 veranschaulicht, Halter 24 angeschraubt, die der Befestigung der Kopfschiene 13 und der Unterschiene 14 dienen. Die Kopfschiene 13 wird gemeinsam mit den Haltern 24 festgeschraubt. Die Befestigung der Unterschiene ist in der Fig. 3 veranschaulicht. Wie daraus ersichtlich, ist die Unterschiene 14 sowohl an ihrer Oberseite als auch an ihrer Unterseite mit T-förmigen Befestigungsgliedern 25 ausgestattet, die mit Kupplungszungen 26, 27 der Halter 24 in Wirkverbindung treten (vgl. Fig. 3).As illustrated in FIG. 1, holders 24 are screwed onto the upper and lower edges of the window 10, which are used to fasten the head rail 13 and the lower rail 14. The head rail 13 is screwed together with the holders 24. The attachment of the lower rail is illustrated in FIG. 3. As can be seen from this, the lower rail 14 is equipped both on its upper side and on its lower side with T-shaped fastening members 25, which come into operative connection with coupling tongues 26, 27 of the holder 24 (cf. FIG. 3).

Die Spannwelle 15 ist in der Fig. 4 vergrößert dargestellt. Wie daraus ersichtlich, besteht diese aus einem Hohlkörper, in die der Achsstumpf 16 einpreßbar ist. Im Kopf des Achsstumpfes 16 ist eine Mehrkant-Aufnahme 28 eingeformt, in welche, wie Fig. 2 veranschaulicht, der Stiftschlüssel 20 eingeführt werden kann.The tensioning shaft 15 is shown enlarged in FIG. 4. As can be seen from this, this consists of a hollow body into which the stub axle 16 can be pressed. A polygonal receptacle 28 is formed in the head of the stub shaft 16, into which, as illustrated in FIG. 2, the key 20 can be inserted.

Wie bereits erwähnt, ist die dargestellte Ausführungsform nur eine beispielsweise Verwirklichung der Erfindung. Diese ist nicht darauf beschränkt. Es sind noch mancherlei Abänderungen und Ausbildungen im Rahmen der Erfindung möglich. So könnte beispielsweise der Achsstumpf 16 mit einem Mehrkantende ausgestattet sein, so daß sich die Spannwelle 15 mit Hilfe eines Schraubenschlüssels 22 verdrehen läßt. Des weiteren könnte die Schraubenmutter 22 durch eine Feder ersetzt werden, die mit einem Sperrzahn zusammenwirkt. Schließlich könnte die Bohrung 19 im Mantel der Spannwelle 15 auch durch einen Schlitz ersetzt werden.As already mentioned, the illustrated embodiment is only one example of realizing the invention. This is not limited to this. There are still various modifications and training possible within the scope of the invention. For example, the stub axle 16 could be equipped with a polygonal end, so that the tensioning shaft 15 can be rotated with the aid of a wrench 22. Furthermore, the nut 22 could be replaced by a spring which interacts with a ratchet tooth. Finally, the bore 19 in the casing of the tensioning shaft 15 could also be replaced by a slot.
