Description

Gegenstand der Erfindung ist eine Antriebsanordnung für eine Raff-Lamellenstore gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a drive arrangement for a Raff slat blind according to the preamble of patent claim 1.

Bekannte Antriebsanordnungen für Raff-Lamellenstoren umfassen eine durch einen Antriebsmotor drehbare Antriebswelle, auf der je nach Breite der Store zwei oder mehr Wende- und Aufzugsvorrichtungen aufgeschoben sind. Die Wende- und Aufzugsvorrichtungen umfassen einerseits Aufzugsmechanismen, mit welchen die Lamellen aufgezogen, d.h. gerafft werden können, und andererseits, verbunden über geeignete Kupplungsmittel, Wendemechanismen, mit welchen über Wendebänder die Neigung der Lamellen einstellbar ist.Known drive arrangements for Raff slat blinds comprise a rotatable drive shaft by a drive motor, are pushed onto the depending on the width of the store two or more turning and elevator devices. The turning and elevator devices comprise on the one hand elevator mechanisms with which the lamellae are mounted, i. can be gathered, and on the other hand, connected via suitable coupling means, turning mechanisms with which the angle of rotation of the slats is adjustable.

Es sind auch Antriebsanordnungen bekannt, bei denen für die Wendemechanismen und für den Aufzugsmechanismus je ein unabhängiger Antriebsmotor vorgesehen ist, was beispielsweise in der DE 29710850 U1 gezeigt ist. Für eine Jalousie mit einem trapezförmigen Behang ist in der DE 199 30 634 A1 gezeigt, dass die Wickelelemente der Zugorgane jeweils durch einen eigenen Antriebsmotor antreibbar sind.There are also drive arrangements are known in which an independent drive motor is provided for the turning mechanisms and for the elevator mechanism, which is for example in the DE 29710850 U1 is shown. For a Venetian blind with a trapezoidal hanging is in the DE 199 30 634 A1 shown that the winding elements of the traction elements are each driven by its own drive motor.

Weiter sind auch sog. Röhrmotoren bekannt, d.h. Motoren, die im Wickelrohr von wickelbaren Sonnenschutzsystemen und Rollladen eingesetzt werden. Auch bei solchen Antriebsanordnungen muss die Leistung des Motors stets an die Grösse der Sonnenschutzvorrichtung und/oder deren Ausbildung angepasst werden.Next are also known. Tubular motors known, ie motors in the winding tube of windable sunscreen systems and Roller shutters are used. Even with such drive arrangements, the power of the engine must always be adapted to the size of the sun protection device and / or their training.

Allen diesen bekannten Antriebsanordnungen ist gemein, dass durch einen meist seitlich oder zwischen den Aufzugs- und Wendevorrichtungen angeordneten Antriebsmotor die gemeinsame Welle, auf der die Aufzugs- und die Wendevorrichtungen gelagert sind, angetrieben wird. Dies bedeutet, dass je nach Grösse der Store, d.h. je nach der Grösse des mit der Store zu bedeckenden Fenster- oder Türausschnitts, ein Antriebsmotor mit entsprechend dimensionierter Antriebsleistung eingesetzt werden muss. Dies bedingt eine Lagerhaltung von Antriebsmotoren unterschiedlicher Leistung und führt folglich zu höheren Lagerkosten und zu geringeren Stückzahlen einzelner Motorentypen und damit höheren Stückkosten.All these known drive arrangements have in common that the common shaft on which the elevator and the turning devices are mounted is driven by a drive motor, which is usually arranged laterally or between the elevator and turning devices. This means that depending on the size of the store, i. Depending on the size of the window or door opening to be covered with the store, a drive motor with correspondingly dimensioned drive power must be used. This requires a storage of drive motors of different performance and thus leads to higher storage costs and lower quantities of individual engine types and thus higher unit costs.

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, eine Antriebsanordnung zu schaffen, mit der die Lagerhaltung der Antriebsmotoren vereinfacht und diese kostengünstiger beschafft werden können.An object of the present invention is to provide a drive assembly, with which the storage of the drive motors can be simplified and this can be procured cost.

Gelöst wird diese Aufgabe durch eine Antriebsanordnung gemäss den Merkmalen des Patentanspruchs 1.This object is achieved by a drive arrangement according to the features of patent claim 1.

Es gelingt durch die direkte Zuordnung je eines Antriebsmotors zu jeder Wende- und Aufzugsvorrichtung, mit einer einzigen Motorengrösse und -leistung bzw. einem einzigen Motorentyp sämtliche gängigen Storen unabhängig von deren Grösse antreiben zu können. Durch die Reduktion auf einen einzigen Motorentyp können diese in grossen Mengen kostengünstig beschafft werden und zudem ist die Lagerhaltung durch eine einzige Wende- und Aufzugsvorrichtung inkl. Antriebsmotor wesentlich vereinfacht. Eine Berechnung der Antriebsleistung entfällt.It succeeds by the direct assignment of each drive motor to each turning and elevator device, with a single engine size and performance or a single engine type to be able to drive all common blinds regardless of their size. Due to the reduction to a single engine type, these can be procured cost-effectively in large quantities and, moreover, storage is considerably simplified by a single reversing and lifting device including a drive motor. A calculation of the drive power is eliminated.

In Figur 1 ist mit Bezugszeichen 1 eine Fenster- oder Türöffnung schematisch dargestellt. In einem Rahmen 3 oder direkt an der bauseitigen oberen Begrenzung der Öffnung sind zwei Wende- und Aufzugsvorrichtungen 5 auf einer Mehrkantwelle 7 angeordnet bzw. die Wende- und Aufzugsvorrichtungen 5 werden von der Mehrkantwelle 7 durchdrungen. Ebenfalls auf der Mehrkantwelle 7 sitzt ein Antriebsmotor 9. Der Antriebsmotor 9 kann statt zwischen den Wende- und Aufzugsvorrichtungen 5 seitlich einer der beiden Wende- und Aufzugsvorrichtungen 5 angeordnet sein und wiederum direkt auf der Mehrkantwelle 7 sitzen oder über ein Getriebe mit dieser in Wirkverbindung stehen. Jede Wende- und Aufzugsvorrichtung bilden jeweils eine Einheit.In FIG. 1 is a window or door opening shown schematically by reference numeral 1. In a frame 3 or directly to the on-site upper boundary of the opening two turning and elevator devices 5 are arranged on a polygonal shaft 7 and the turning and Elevator devices 5 are penetrated by the polygonal shaft 7. Also located on the polygonal shaft 7 is a drive motor 9. The drive motor 9 can be arranged between the turning and elevator devices 5 side of one of the two turning and lifting devices 5 and in turn sit directly on the polygonal shaft 7 or via a transmission with this in operative connection , Each turning and lifting device each form a unit.

Am Aufzugsteil 5' der Wende- und Aufzugsvorrichtung 5 sind Aufzugsbänder 11 auf- und abspulbar befestigt. Deren freie Enden 11' sind mit einer Endschiene 13 verbunden. Die Aufzugsbänder 11 durchdringen die Lamellen 15, die den Behang bzw. die Rafflamellenstore 17 bilden. Am Wendemechanismus 5" der Wende- und Aufzugsvorrichtung 5 sind Wendebänder 19 befestigt und stehen in Verbindung mit den Kanten der Lamellen 15. Der Aufbau der Lamellenstore 17 sowie derjenige der Wende- und Aufzugsvorrichtung 5 ist bekannt und er wird daher nicht näher erläutert.At the elevator part 5 'of the turning and elevator device 5 elevator belts 11 are fastened up and down. Their free ends 11 'are connected to a rail 13. The elevator belts 11 penetrate the slats 15, which form the curtain or the Rafflamellenstore 17. Turning tapes 19 are fastened and are connected to the edges of the fins 15 on the turning mechanism 5 "of the turning and lifting device 5. The construction of the finned blind 17 and that of the turning and lifting device 5 are known and will therefore not be explained in detail.

In gebrochenen Linien ist in Figur 1 eine breitere Fensteröffnung 1' angedeutet, in welcher eine zusätzliche Wende- und Aufzugsvorrichtung 5 auf der Mehrkantwelle 7 angeordnet ist, um die längeren Lamellen 15 im geeigneten Abstand zu tragen. In Figur 1 ist weiter ersichtlich, dass bei einer grösseren Fensteröffnung 1 (gebrochene Linien) auch ein grösserer, d.h. leistungsstärkerer Antriebsmotor 9 (in gebrochenen Linien dargestellt) notwendig ist.In broken lines is in FIG. 1 a wider window opening 1 'indicated, in which an additional turning and elevator device 5 is arranged on the polygonal shaft 7 in order to carry the longer fins 15 at a suitable distance. In FIG. 1 is also apparent that with a larger window opening 1 (broken lines) and a larger, ie more powerful drive motor 9 (shown in broken lines) is necessary.

In Figur 2 ist dieselbe Fensteröffnung 1 ersichtlich, und es ist wiederum eine Rafflamellenstore 17 mit Aufzugsbändern 11 und Wendebändern 19 dargestellt. Im Rahmen 3, welcher in der Fensteröffnung 1 befestigt ist, sind erfindungsgemäss zwei Gehäuse 21 sichtbar. Diese sind an gleicher Stelle wie die Wende- und Aufzugsvorrichtungen 5 im Stand der Technik (Fig. 1) im Rahmen 3 oder direkt in der Fensteröffnung angeordnet und zudem daran befestigt. Sie umfassen jedoch nicht nur die Wende- 5" und Aufzugsmechanismen 5', sondern in jedem der beiden Gehäuse 21 wird eine Wende- und Aufzugsvorrichtung 5 durch einen individuellen Antriebsmotor 9 angetrieben (vgl. Figuren 3 und 4). Der Antriebsmotor 9 sitzt innerhalb des gemeinsamen Gehäuses 21 für die Wende- und Aufzugsvorrichtung 5 sowie den Antriebsmotor 9.In FIG. 2 is the same window opening 1 can be seen, and it is again a Rafflamellenstore 17 with elevator belts 11 and turning belts 19 shown. In the frame 3, which is fixed in the window opening 1, according to the invention, two housings 21 are visible. These are in the same place as the turning and elevator devices 5 in the prior art ( Fig. 1 ) in frame 3 or directly in the window opening and also attached thereto. However, they include not only the turning and elevator mechanisms 5 ', but in each of the two housings 21 a turning and lifting device 5 is driven by an individual drive motor 9 (see FIG. FIGS. 3 and 4 ). The drive motor 9 is seated within the common housing 21 for the turning and elevator device 5 and the drive motor. 9

In der ersten Ausführungsform gemäss Figur 3 ist die an sich bekannte Wende- und Aufzugsvorrichtung 5 direkt mit der Abtriebswelle 23 des Antriebsmotors 9 verbunden. Die Leistung des Antriebsmotors 9 entspricht beispielsweise der Hälfte der Leistung des herkömmlichen Antriebsmotors in Figur 1 (Stand der Technik). Im weiteren fehlt, und dies ist aus Figur 2 ersichtlich, eine entsprechend dimensionierte Welle (Mehrkantwelle) 7, mit welcher das Drehmoment des Antriebsmotors bisher auf alle Wende- und Aufzugsvorrichtungen 5 übertragen wird. Zur Bewegungs-Synchronisation der autonomen erfindungsgemässen Wende-und Aufzugsvorrichtungen 5 kann wiederum eine Mehrkantwelle 7' mit wesentlich geringerem Durchmesser eingesetzt werden. Es kann aber auch eine rein steuerungsseitige Verbindung zwischen den als Elektromotoren ausgebildeten Antriebsmotoren 9 vorliegen, um diese zu synchronisieren bzw. bei Auftreffen des Lamellenstores 17 auf ein Hindernis zu synchronisieren oder auszuschalten.In the first embodiment according to FIG. 3 is the known turning and elevator device 5 directly connected to the output shaft 23 of the drive motor 9. The power of the drive motor 9 corresponds to, for example, half the power of the conventional drive motor in FIG. 1 (State of the art). In the further missing, and this is out FIG. 2 can be seen, a correspondingly dimensioned shaft (polygonal shaft) 7, with which the torque of the drive motor has been transferred to all turning and elevator devices 5 so far. For movement synchronization of the autonomous inventive turning and elevator devices 5 can turn a Polygonal shaft 7 'can be used with a much smaller diameter. But it may also be a purely control-side connection between the drive motors designed as an electric motor 9 to synchronize these or synchronize upon impact of the slat blind 17 to an obstacle or turn off.

Im zweiten Ausführungsbeispiel gemäss Figur 4 ist zwischen dem Antriebsmotor 9 und der Wende- und Aufzugsvorrichtung 5 ein Getriebe 25 angeordnet. Im dargestellten Beispiel handelt es sich um ein Planetengetriebe, bei dem am Gehäuse 21, das sowohl die Wende- und Aufzugsvorrichtung 5 als auch den Antriebsmotor 9 aufnimmt, eine Innenverzahnung 27 angeformt ist, auf der die Planetenräder 29 kämmen. Im Zentrum kämmen die Planetenräder 29 auf einem Antriebszahnrad 31, welches auf der Abtriebswelle 23 des Antriebsmotors 9 sitzt. Die Planetenräder 29 sind entweder direkt an der Wende- und Aufzugsvorrichtung 5 auf entsprechenden, an der Wende- und Aufzugsvorrichtung 5 ausgebildeten Wellenstummeln 33 gelagert (Figur 4) oder indirekt auf einer entsprechenden Tragscheibe 35 (in gebrochenen Linien in Figur 4 dargestellt). Letztere ist ihrerseits mit der Wende- und Aufzugsvorrichtung 5 fest verbunden. Selbstverständlich könnte die Innenverzahnung 27 auch an einem unabhängig vom Gehäuse 21 in dieses eingesetzten Ring angeordnet sein. Anstelle eines Planetenantriebes kann selbstverständlich auch ein Wolfromgetriebe, ein Exzentergetriebe oder ein Schneckengetriebe in das gemeinsame Gehäuse 21 eingesetzt sein.In the second embodiment according to FIG. 4 is disposed between the drive motor 9 and the turning and elevator device 5, a transmission 25. In the example shown, it is a planetary gear, in which on the housing 21, which accommodates both the turning and elevator device 5 and the drive motor 9, an internal toothing 27 is integrally formed, on which the planet gears 29 mesh. In the center, the planet gears 29 mesh on a drive gear 31, which sits on the output shaft 23 of the drive motor 9. The planetary gears 29 are mounted either directly on the turning and elevator device 5 on corresponding, formed on the turning and elevator device 5 stub shafts 33 ( FIG. 4 ) or indirectly on a corresponding support plate 35 (in broken lines in FIG. 4 shown). The latter is in turn firmly connected to the turning and elevator device 5. Of course, the internal toothing 27 could also be arranged on a ring used independently of the housing 21 in this. Instead of a planetary drive, of course, a Wolfromgetriebe, an eccentric or a worm gear can be used in the common housing 21.

Aus Figur 2 ist weiter ersichtlich, dass, in Abhängigkeit von der Breite b und der Höhe h der Fensteröffnung, die entsprechende Anzahl der motorisierten Wende- und Aufzugsvorrichtungen 5 eingesetzt werden muss. Bei sehr grosser Höhe der Lamellenstore 17 kann der Abstand x zwischen zwei Wende- und Aufzugsvorrichtungen 5 entsprechend verkleinert werden.Out FIG. 2 It can also be seen that, depending on the width b and the height h of the window opening, the corresponding number of motorized turning and elevator devices 5 must be used. At a very high height of the slat blind 17, the distance x between two turning and elevator devices 5 can be reduced accordingly.
