Abstract

Un arbre d'enroulement (2) est actionné au moyen d'une chaîne à grains de chapelet (10). Il est relié à des tambours d'enroulement (3) par des engrenages à vis sans fin (4, 5). Les tambours d'enroulement (3) sont d'une pièce avec la roue tangente (4), laquelle est apte à tourner dans un boîtier (13). Au montage du rideau, les axes des roues tangentes (4) sont horizontaux et disposés perpendiculairement à l'arbre d'enroulement (2). Le rapport de transmission des engrenages à vis sans fin (4, 5) est choisi de façon que le mécanisme de remontage soit autobloquant. Un dispositif auxiliaire de freinage n'est donc pas nécessaire. Le rideau à retrousser convient aussi pour les fenêtres inclinées ainsi que pour les hautes fenêtres et pour les rideaux faits de lourds tissus (8).A winding shaft (2) is actuated by means of a chained grain chain (10). It is connected to winding drums (3) by worm gears (4, 5). The winding drums (3) are in one piece with the tangent wheel (4), which is capable of rotating in a housing (13). When mounting the curtain, the axes of the tangent wheels (4) are horizontal and arranged perpendicular to the winding shaft (2). The transmission ratio of the worm gears (4, 5) is chosen so that the winding mechanism is self-locking. An auxiliary braking device is therefore not necessary. The roll-up curtain is also suitable for tilted windows as well as for tall windows and for curtains made of heavy fabrics (8).

Description

R a f f v o r h a n g R a f f before r a n g
Die Erfindung betrifft einen Raffvorhang nach dem Ober¬ begriff des unabhängigen Anspruchs 1.The invention relates to a Roman blind according to the preamble of independent claim 1.
Im Stand der Technik ist ein solcher Raffvorhang durch die US-A-2 676 654 bekannt. Bei diesem sind die Wickelrollen ohne axiales Spiel fest mit der Wickelwelle verbunden und neben jeder Wickelrolle ist ein separater Lagerbock ange¬ ordnet, der an der Gebäudewand befestigt ist.Such a Roman blind is known in the prior art from US-A-2,676,654. In this case, the winding rollers are firmly connected to the winding shaft without axial play, and a separate bearing block is arranged next to each winding roller and is fastened to the building wall.
Durch die EP-A-0 118 700 ist ein Raffvorhang dieser Gattung bekannt, bei dem die Wickelrollen mit axialem Spiel in Achsrichtung der Wickelwelle verschiebbar sind und bei dem ebenfalls jeder Wickelrolle ein Lagerbock und ausser- dem ein Stellring zugeordnet sind. Bei diesen Raffvorhängen besteht die Schwierigkeit, dass sie für Schrägfenster, bei denen die Wickelwelle schräg angeordnet ist, nicht verwendet werden können und infolge der begrenzten Platzverhältniεse hinter dem Vorhang die Schnur- oder Bandaufnahme der Wickelrollen auf etwa 3 m beschränkt sind.From EP-A-0 118 700 a gathering curtain of this type is known, in which the winding rollers can be displaced with axial play in the axial direction of the winding shaft and in which a bearing block and also an adjusting ring are also assigned to each winding roller. The problem with these shirring curtains is that they cannot be used for inclined windows in which the winding shaft is arranged at an angle, and because of the limited space behind the curtain, the cord or tape take-up of the winding rolls is limited to approximately 3 m.
Der Erfindung liegt die Aufgabe zugrunde, einen Raffvor¬ hang der genannten Gattung zu schaffen, der diese Schwie¬ rigkeiten vermeidet und der trotzdem einfach montierbar und funktionssicher ist.The invention has for its object to provide a Raffvor¬ curtain of the type mentioned, which avoids these difficulties and which is still easy to install and reliable.
Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst.The object is achieved by the invention according to claim 1.
Auch bei einer starken Schrägstellung der Wickelwelle werden Aufzugschnüre und Aufzugbänder ohne zu streifen ein¬ wandfrei aufgespult, weshalb sich der erfindungsgemässe Raffvorhang besonders auch für Schrägfenster eignet. Der Durchmesser ist nicht auf den Abstand zwischen Vorhang und Fenster begrenzt und kann wesentlich grösser und ent¬ sprechend der Vorhang länger sein. Eine Beschädigung des Vorhangstoffes durch tangentiales Streifen an den Wickel¬ rollen wird beim erfindungsge ässen Raffvorhang vermieden. Separate Lagerböcke sind entbehrlich, was die Montage und die Lagerhaltung wesentlich vereinfacht.Even when the winding shaft is strongly inclined, elevator cords and elevator belts are wound up without streaking, which is why the inventive venetian blind is particularly suitable for inclined windows. The diameter is not limited to the distance between the curtain and the window and can be much larger and, accordingly, the curtain can be longer. Damage to the curtain material by tangential stripes on the winding rolls is avoided in the inventive venetian blind. Separate pillow blocks are unnecessary in terms of assembly and the inventory is simplified considerably.
Durch die Weiterbildung nach Anspruch 2 wird in konstruk¬ tiv einfacher Weise eine Bremseinrichtung geschaffen, durch die der Vorhang in jeder gewünschten Zwischenstel¬ lung selbsttätig arretiert wird.Through the development according to claim 2, a braking device is created in a structurally simple manner, by means of which the curtain is automatically locked in any desired intermediate position.
Durch die Weiterbildung nach Anspruch 3 wird ein Raffvor¬ hang geschaffen, der eine zusätzliche Bremsvorrichtung er¬ übrigt und mit dem durch das Uebersetzungεverhältnis des Schneckengetriebes auch schwere Vorhänge mit geringem Kraftaufwand hochgezogen werden können.Through the development according to claim 3, a gathering curtain is created which eliminates the need for an additional braking device and with which, due to the ratio of the worm gear, even heavy curtains can be pulled up with little effort.
Eine hohe Abspulgeschwindigkeit und eine Zerstörung der Wickeleinrichtung, des Bedienungselements oder des Vor¬ hangstoffes infolge einer grossen Massenverzögerung wird vermieden. Ebenfalls dürften Unfälle durch ein mit grosser Geschwindigkeit heruntersausendes Beschwerungsprofil beim erfindungsgemässen Raffvorhang nicht mehr vorkommen.A high unwinding speed and destruction of the winding device, the operating element or the curtain material as a result of a large delay in mass are avoided. Likewise, accidents due to a weight profile that drops down at great speed should no longer occur in the inventive venetian blind.
Durch die Weiterentwicklung nach Anspruch 5 wird verhin¬ dert, dass sich das Aufzugelement beim Auf- oder Abspulen verfangen kann und eine besonders einfache Montage ermög¬ licht. Bei den Ausführungen nach den Ansprüchen 9 und 10 ist ein selbsthemmendes Schneckengetriebe zwischen dem Antriebs¬ organ und der Wickelwelle angeordnet. Hier können die Ge¬ triebe zwischen den Wickelrollen und der Wickelwelle übliche kostengünstige Getriebe ohne Selbsthemmung sein. Vorzugsweise ist ein Antriebsrad so gelagert, dass seine Drehachse senkrecht zur Wickelwelle steht, so dass eine ähnliche Anordnung wie bei den Wickelrollen vorliegt.The further development according to claim 5 prevents the elevator element from getting caught when winding or unwinding and enables particularly simple assembly. In the embodiments according to claims 9 and 10, a self-locking worm gear is arranged between the drive member and the winding shaft. Here, the gearboxes between the winding rollers and the winding shaft can be conventional inexpensive gearboxes without self-locking. A drive wheel is preferably mounted in such a way that its axis of rotation is perpendicular to the winding shaft, so that there is an arrangement similar to that of the winding rollers.
Vorteilhafte Weiterbildungen ergeben sich aus den übrigen abhängigen Ansprüchen.Advantageous further developments result from the remaining dependent claims.
Ausführungsbeispiele der Erfindung werden nachfolgend an¬ hand der Zeichnungen näher erläutert. Es zeigen:Exemplary embodiments of the invention are explained in more detail below with reference to the drawings. Show it:

Die Fig. 1 zeigt einen vertikal hängenden Vorhangstoff 8, an dem ein Gewichtsprofil 9 angebracht ist. Mehrere im Ab¬ stand und parallel zueinander angeordnete Aufzugbänder 6 sind jeweils an einem Ende am Gewichtsprofil 9 und am anderen Ende in einem Schlitz 34 der Wickelrolle 3 (Fig. 2) festgeklemmt. Zwischen ihren Enden sind die Aufzugbänder 6 mittels Oesen 7 geführt, die am Vorhangstoff 8 befestigt sind, und durch welche die Aufzugbänder 6 leicht verschieb¬ bar hindurchgezogen sind.Fig. 1 shows a vertically hanging curtain fabric 8, on which a weight profile 9 is attached. A plurality of elevator belts 6, which are spaced apart and parallel to one another, are each clamped at one end to the weight profile 9 and at the other end in a slot 34 in the winding roll 3 (FIG. 2). Between their ends, the elevator belts 6 are guided by means of eyelets 7, which are fastened to the curtain fabric 8 and through which the elevator belts 6 are pulled so that they can be moved easily.
Die Achsen der Wickelrollen 3 sind horizontal und im rech¬ ten Winkel zu einer Wickelwelle 2 angeordnet, die mit einem Antriebsrad 12 verbunden ist, das mittels einer Kugelkette angetrieben werden kann. Bei einem üblichen Fenster ist die Wickelwelle 2 horizontal und bei einem Raffvorhang für ein Schrägfenster geneigt angeordnet. Eine Vorhangschiene 1 verläuft parallel zur Wickelwelle 2 und ist in üblicher Weise an der Decke, an der Wand oder am Fenster befestigt. An dieser Vorhangschiene 1 ist wie in Fig. 2 gezeigt der Vorhangstoff 8 mittels Flor- und Ketten¬ band 28 lösbar befestigt. Um den Vorhang zu betätigen, wird an der Kugelkette 10 gezogen, wobei im Fall des Raffvor- hangs für ein Schrägfenster unterhalb des Antriebsrads 12 eine Führungsrolle 11 angebracht ist. In der einen Zugrich¬ tung der endlosen Kugelkette 10 werden die AufZugbänder 6 auf die Wickelrollen 3 aufgewickelt und der Vorhang hoch¬ gezogen während in der anderen Zugrichtung die Aufzugbänder 6 synchron abgespult und der Vorhang heruntergelassen wird. Wie weiter unten näher erläutert ist, bleibt der Vorhang nach dem Loslassen der Kugelkette in jeder Position selbst¬ tätig sofort stehen.The axes of the winding rollers 3 are arranged horizontally and at right angles to a winding shaft 2 which is connected to a drive wheel 12 which can be driven by means of a ball chain. In the case of a conventional window, the winding shaft 2 is arranged horizontally and, in the case of a Roman blind for an oblique window, it is inclined. A curtain rail 1 runs parallel to the winding shaft 2 and is attached in the usual way to the ceiling, wall or window. As shown in FIG. 2, the curtain fabric 8 is detachably attached to this curtain rail 1 by means of pile and chain tape 28. In order to actuate the curtain, the ball chain 10 is pulled, whereby in the case of the shirring curtain for an oblique window below the drive wheel 12 a guide roller 11 is attached. In one pulling direction of the endless ball chain 10, the pull-up belts 6 are wound onto the winding rollers 3 and the curtain is pulled up, while in the other pulling direction the lift belts 6 are unwound synchronously and the curtain is lowered. As explained in more detail below, the curtain stops automatically in any position after the ball chain is released.
ie die Fig. 2 bis 4 zeigen, sind die Wickelrollen 3 jeweils in einem Gehäuse gelagert, das im wesentlichen aus einem Gehäusekörper 13 und zwei lösbar auf diesen aufgesetzten Deckeln 14 und 15 besteht. Am Gehäusekörper 13 sind oben zwei im Abstand angeordnete Bügel angeformt, die in die Vorhangschiene 1 lösbar und in Längsrichtung verschiebbar eingesetzt sind.2 to 4, the winding rollers 3 are each mounted in a housing which essentially consists of a housing body 13 and two covers 14 and 15 which are detachably placed on these. On the housing body 13 two spaced brackets are integrally formed, which are detachably inserted in the curtain rail 1 and displaceable in the longitudinal direction.
Der Gehäusekörper 13 weist eine vertikale Wand 32 auf, welche das Gehäuse in zwei Kammern 30 und 31 unterteilt. In der Kammer 30 ist die Wickelrolle 3 mit dem Bandwickel 19 untergebracht. Im unteren Teil der Kammer 30 befindet sich ein enger Schlitz 21, in dem das AufZugband 6 geführt ist. Dieser Schlitz 21 verhindert eine Verdrehung des Bandes 6 in der Kammer 30 und damit eine Störung bei der Bildung des Wickels 19. Die Kammer 30 weist ausserdem einen lösbar aufgesetzten Deckel 15 auf, der auf der Innenseite einen in die Wickelrolle 3 eingreifenden und diesen führen¬ den Vorsprung 22 aufweist. Die Wickelrolle 3 ist an einem Schneckenrad 4 angeformt, das in einer Oeffnung 16 der Wand 32 und mit einem Lagerzapfen 24 in einer Oeffnung 33 eines weiteren Deckels 14 gelagert ist. Die Zähne 18 des Schneckenrads 4 kämmen mit einer Schnecke 5, die am Gehäuse¬ teil 13 und am Deckel 14 gelagert ist. Das Schneckenrad 5 ist drehfeεt und in Längsrichtung verschiebbar mit der Wickelwelle 2 verbunden. Oft ist es erforderlich, einen Wickel 19 zu spannen oder etwas zu lösen, damit alle Bän¬ der 6 den Vorhangstoff 8 genau synchron hochziehen. Dies lässt sich in einfacher Weise dadurch erreichen, dass das Schneckenrad 4 bei abgenommenem Deckel 15 an der Wickel¬ rolle 3 aus der Kammer 31 herausgezogen und im entkoppel¬ ten Zustand in der einen oder anderen Richtung gedreht wird und damit der Schlitz 34 verstellt wird.The housing body 13 has a vertical wall 32 which divides the housing into two chambers 30 and 31. The winding roll 3 with the tape roll 19 is accommodated in the chamber 30. In the lower part of the chamber 30 there is a narrow slot 21, in which the winding band 6 is guided. This slot 21 prevents rotation of the band 6 in the chamber 30 and thus a disturbance in the formation of the roll 19. The chamber 30 also has one Detachably attached cover 15, which on the inside has a projection 22 which engages in the winding roll 3 and guides it. The winding roll 3 is formed on a worm wheel 4, which is mounted in an opening 16 of the wall 32 and with a bearing journal 24 in an opening 33 of a further cover 14. The teeth 18 of the worm wheel 4 mesh with a worm 5 which is mounted on the housing part 13 and on the cover 14. The worm wheel 5 is connected to the winding shaft 2 in a rotationally fixed manner and displaceable in the longitudinal direction. It is often necessary to tension a wrap 19 or to loosen something so that all the tapes 6 pull the curtain fabric 8 up precisely in synchronism. This can be achieved in a simple manner by pulling the worm wheel 4 out of the chamber 31 with the cover 15 on the winding roll 3 removed and rotating it in one or the other direction in the uncoupled state and thus adjusting the slot 34.
Aus den obigen Angaben ergibt sich somit ein RaffVorhang, der trotz der erheblichen Vorteile ersichtlich verhältnis- mäεsig wenige, robuste und einfache Bauteile aufweist und der auch in der Anwendung als Raffvorhang für ein Schräg¬ fenster oder sehr hohes Fenster den praktiεchen Anforde¬ rungen einschliesslich sehr schonender Behandlung des Vor¬ hangstoffes in hervorragender Weise Rechnung trägt und der zudem in der Herstellung günstig und betrieblich sehr zu¬ verlässig ist. Das Uebersetzungsverhältnis des Schneckengetriebes ist εo gewählt, dass der Aufzug selbεthem end iεt, wobei die Rei¬ bung der bewegten Teile berücksichtigt sind. Ist die Schnecke 5 aus Nylon und das Schneckenrad 4 aus Delrin her¬ gestellt, so wird eine Selbsthemmung mit einer Uebersetzung von etwa 1 : 4,2 erreicht. Ohne Reibung müsste das Ueber¬ setzungsverhältnis etwa 1 : 6 sein, damit Selbsthemmung auf¬ tritt. Es hat sich gezeigt, dass ein Uebersetzungεverhält- niε von etwa 1:4 für einen RaffVorhang vorteilhaft iεt. Einerεeitε können auch εchwere Vorhänge mit geringem Kraft¬ aufwand betätigt werden und anderεeits ist das Ueber- εetzungsverhältnis doch nicht so gross, dass sich der Vor¬ hang zu langsam bewegt. Die Selbsthemmung bewirkt, dass der Vorhang auch in jeder Zwischenεtellung beim Loslassen der Kugelkette sofort in der erreichten Poεition εtehen- bleibt. Damit wird inεbeεondere verhindert, daεs das Gewichtsprofil 9 bei einem unbeabsichtigen Loslassen der Kugelkette 10 nach unten saust und eine Person verletzen oder den Vorhang beschädigen kann.The above information thus results in a venetian blind which, despite the considerable advantages, has a comparatively few, robust and simple components and which, when used as a venetian blind for an oblique window or very tall window, also includes the practical requirements very much careful handling of Vor¬ hang substance in an excellent manner and takes account of the addition in manufacturing low and operationally very reliably is to ¬. The gear ratio of the worm gear is chosen so that the elevator ends itself, taking into account the friction of the moving parts. If the worm 5 is made of nylon and the worm wheel 4 is made of Delrin, self-locking with a ratio of about 1: 4.2 is achieved. Without friction, the transmission ratio would have to be about 1: 6 for self-locking to occur. It has been shown that a translation ratio of approximately 1: 4 is advantageous for a gathering curtain. On the one hand, heavy curtains can be operated with little effort and on the other hand the transmission ratio is not so great that the curtain moves too slowly. The self-locking effect means that the curtain immediately remains in the position it has reached in any intermediate position when the ball chain is released. This in particular prevents the weight profile 9 from whizzing downwards when the ball chain 10 is released unintentionally and can injure a person or damage the curtain.
Der Deckel 14 iεt mittels einer Schnappvorrichtung 20 am Gehäuεekörper 13 löεbar befeεtigt. Mit einer ähnlichen Schnappvorrichtung iεt auch der Deckel 15 am Gehäusekörper 13 befestigt. Wie ersichtlich, ist die Aufwickelrolle 3 im Gehäuεe eingeεchlossen und εind auch sonst keine drehenden Teile vorhanden, welche am Vorhangstoff anstehen und die¬ sen beschädigen könnten. Da der Gehäusekörper 13 auf der Wickelwelle 2 stufenlos verschiebbar ist, ist es in jedem Fall möglich, den Schlitz 21 genau auf die Linie der Oesen 7 zu bringen. In der gewählten Position kann dann der Gehäusekörper 13 immer an der Vorhangschiene 1 befeεtigt werden.The cover 14 is detachably attached to the housing body 13 by means of a snap device 20. The cover 15 is also attached to the housing body 13 with a similar snap device. As can be seen, the take-up roll 3 is enclosed in the housing and is not otherwise rotating Parts are present which are in contact with the curtain fabric and could damage it. Since the housing body 13 is continuously displaceable on the winding shaft 2, it is possible in any case to bring the slot 21 exactly on the line of the eyelets 7. In the selected position, the housing body 13 can then always be attached to the curtain rail 1.
Bei einer weiteren, nicht dargestellten Ausführung sind die Getriebe zwischen den Wickelrollen und der Wickelwelle übliche Kreuzgetriebe ohne Selbsthemmung. Hingegen ist hier die Antriebsrolle 12 über ein selbsthemmendes Schnek- kengetriebe mit der Wickelwelle verbunden. Vorzugsweise iεt die Antriebsrolle 12 ähnlich wie eine Wickelrolle mit ihrer Drehachεe quer zur Wickelwelle an der Schiene 1 in einem Gehäuεe gelagert. Dieεe Ausführung ist wesentlich kostengünεtiger, da lediglich ein Schneckengetriebe vorge- εehen iεt. In a further embodiment, not shown, the gears between the winding rollers and the winding shaft are conventional cross gears without self-locking. On the other hand, the drive roller 12 is connected to the winding shaft via a self-locking worm gear. Preferably, the drive roller 12, like a winding roller, is mounted with its axis of rotation transversely to the winding shaft on the rail 1 in a housing. This design is significantly less expensive since only a worm gear is provided.
