EP 0 152 888 A2 offenbart einen Rohrmotor für Rollläden mit zwei kleinen Elektrogleichstrommotoren, die jeweils eine Gewindespindel zum Positionieren von jeweils einem Schalterträger antreiben. Die Positionen der Schalterträger bestimmen die Abschaltpunkte des Rollladens beim Auf- und Ablassen. Zwischen den kleinen Elektrogleichstrommotoren und den Gewindespindeln ist jeweils ein einfaches mehrstufiges Stirnradgetriebe geschaltet. Das Untersetzungsverhältnis beträgt beispielsweise 1000:1, so dass eine äußerst feinfühlige Verstellung des jeweiligen Schalterträgers möglich ist. Eine spezielle Ausführungsform sieht die Verwendung einer Schaltkupplung vor, um die zwei kleinen Elektrogleichstrommotoren alternierend auf die eine oder die andere Gewindespindel wirken zu lassen. EP 0 152 888 A2 discloses a tubular motor for roller shutters with two small electric DC motors, each driving a threaded spindle for positioning each of a switch carrier. The positions of the switch carrier determine the shut-off points of the roller shutter during loading and unloading. Between the small electric DC motors and the threaded spindles a simple multi-stage spur gear is connected in each case. The reduction ratio is for example 1000: 1, so that an extremely sensitive adjustment of the respective switch carrier is possible. A special embodiment provides for the use of a clutch to allow the two small DC electric motors to act alternately on one or the other threaded spindle.

Sämtliche motorisch betriebene Antriebsvorrichtungen beinhalten einen Antriebsmotor und ein Getriebe, bei denen die kinematischen Übersetzungsbedingungen nicht veränderbar sind. Die Drehzahl des Antriebsmotors sowie die Getriebeübersetzung zwischen der Antriebswelle des Antriebsmotors und der Ausgangswelle des Getriebes bestimmen die Geschwindigkeit, mit der der Rollladen auf- bzw. abgewickelt wird. Ferner bestimmt das Drehmoment des Antriebsmotors und die Getriebeübersetzung die Zugkraft der Antriebsvorrichtung. Jede motorisch betriebene Antriebsvorrichtung stellt einen Kompromiss zwischen derAll motorized drive devices include a drive motor and a transmission in which the kinematic translation conditions are not changeable. The speed of the drive motor and the gear ratio between the drive shaft of the drive motor and the output shaft of the transmission determine the speed at which the shutter is wound or unwound. Further, the torque of the drive motor and the gear ratio determines the tensile force of the drive device. Each motorized drive device represents a compromise between the

Geschwindigkeit des Rollladens und der Zugkraft der Antriebsvorrichtung dar.Speed of the shutter and the traction of the drive device is.

Der Vielfalt der Rollläden in Bezug auf Größe, Material usw. kann damit nicht mit einer einzigen motorisch betriebenen Antriebsvorrichtung entsprochen werden. Die Folge sind einerseits unerwünschte Betriebsbedingungen (Überlastung), die außerhalb des optimalen Wirkungsgrades des Antriebsmotors liegen, wodurch die Antriebsmotortemperatur und der Energieverbrauch negativ beeinflusst werden. Läuft der Antriebsmotor andererseits mit deutlicher Unterlast, wird auf eine höhere Geschwindigkeit des Rollladens verzichtet.The variety of shutters in terms of size, material, etc. can not be met with a single motor-driven drive device. The result is on the one hand undesirable operating conditions (overload), which are outside the optimal efficiency of the drive motor, whereby the drive motor temperature and energy consumption are adversely affected. On the other hand, if the drive motor runs with significant underload, a higher speed of the roller shutter is dispensed with.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebsvorrichtung der angegebenen Gattung zu schaffen, bei der die Betriebsbedingungen optimiert sind, die für eine größere Anzahl von unterschiedlichen Rollläden verwendet werden kann, wobei die Lagerhaltungskosten wesentlich reduziert sind, und die relativ schnell und einfach auch von Heimwerkern an den jeweiligen Rollladen angepasst werden kann.The invention has for its object to provide a drive device of the type specified, in which the operating conditions are optimized, which can be used for a larger number of different shutters, the storage costs are substantially reduced, and relatively quickly and easily by do-it-yourselfers can be adapted to the respective roller shutter.

Diese Aufgabe wird erfindungsgemäß durch eine Antriebsvorrichtung mit den Kennzeichnungsmerkmalen des Patentanspruchs 1 gelöst.This object is achieved by a drive device with the characterizing features of claim 1.

Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.

Bei der erfindungsgemäßen Antriebsvorrichtung ist das Getriebe als Schaltgetriebe mit mindestens zwei unterschiedlichen Übersetzungen ausgebildet. Diese besondere Ausbildung ermöglicht eine Anpassung der Antriebsvorrichtung an unterschiedliche Rollläden entsprechend deren Beschaffenheit in Bezug auf Größe, Material usw..In the drive device according to the invention, the transmission is designed as a manual transmission with at least two different translations. This special design allows adaptation of the drive device to different shutters according to their nature in terms of size, material, etc.

Die Antriebsvorrichtung kann als elektrischer Gurtwickler für das Gurtband o.dgl. Zugelement der Verdunkelungsvorrichtung ausgebildet sein, wobei der Gurtwickler dazu ausgebildet und bestimmt ist, fest an einer Wand oder in einem Mauerwerksausnehmungsgehäuse montiert zu werden. Dabei ist an dem Gehäuse des Gurtwicklers eine Betätigungsvorrichtung für die Umschaltung des Getriebes vorgesehen. Durch die Ausbildung der Antriebsvorrichtung als Gurtwickler und die Betätigungsvorrichtung für die Umschaltung des Getriebes an dem Gehäuse gestaltet sich die Montage und die Umschaltung des Getriebes der Antriebsvorrichtung sehr einfach, so dass dieses auch relativ unproblematisch durch Heimwerker erfolgen kann. Eine Zerlegung des Getriebes zur Veränderung des Übersetzungsverhältnisses ist nicht notwendig, so dass hier eine sehr einfache Bedienung im Vordergrund steht.The drive device may or the like as electric Gurtwickler for the webbing. Traction element of the obscuring device may be formed, wherein the Gurtwickler is designed and intended to be fixedly mounted on a wall or in a Mauerwerksausnehmungsgehäuse. It is on the case Gurtwicklers provided an actuator for the switching of the transmission. Due to the design of the drive device as Gurtwickler and the actuator for the switching of the transmission to the housing, the assembly and switching of the transmission of the drive device designed very simple, so that this can be done relatively easily by do-it-yourselfers. A disassembly of the transmission to change the gear ratio is not necessary, so here is a very simple operation in the foreground.

Die Betätigungsvorrichtung kann ein schwenk- und/oder verschiebbarer Hebel sein, der auf eine in dem Getriebe angeordnete, auf einer Abtriebswelle eines Zahnrades verdrehsicher gelagerte Schiebehülse mit an deren Enden vorzugsweise einstückig angeformten weiteren Zahnrädern mit unterschiedlichen Teilkreisdurchmessern wirkt und beim Umschalten des Getriebes die Schiebehülse mit den Zahnrädern in axialer Richtung verschiebt.The actuating device may be a pivotable and / or displaceable lever which acts on a transmission sleeve mounted in the transmission, on an output shaft of a gear rotatably mounted sliding sleeve with preferably integrally formed at its ends further gears with different pitch diameters and when switching the transmission with the sliding sleeve shifts the gears in the axial direction.

Vorzugsweise ist die Betätigungsvorrichtung in eine Ausnehmung des Gehäuses des Gurtwicklers integriert, die von einer auf das Gehäuse aufsetzbaren schalenförmigen Abdeckblende des Gurtwicklers abgedeckt ist. Durch die Integration der Betätigungsvorrichtung bzw. des Hebels in die Ausnehmung im Gehäuse und die auf das Gehäuse aufsetzbare Abdeckblende ist die Betätigungsvorrichtung bzw. der Hebel im normalen Betrieb der Antriebsvorrichtung von außen nicht erkennbar und ein unbeabsichtigtes Umschalten des Getriebes ist weitestgehend ausgeschlossen.Preferably, the actuating device is integrated in a recess of the housing of the Gurtwicklers, which is covered by an attachable to the housing cup-shaped Abdeckblende the Gurtwicklers. By integrating the actuating device or the lever in the recess in the housing and the cover plate can be placed on the housing, the actuating device or the lever during normal operation of the drive device from the outside is not visible and a unintentional switching of the gearbox is largely excluded.

Der Hebel ist vorzugsweise in Ruhestellung in der Ausnehmung im Gehäuse gegen Längsverschiebung gesichert, so dass beispielsweise eine automatische Umschaltung des Getriebes aufgrund von Vibrationen ausgeschlossen ist.
