Description

Die Erfindung betrifft ein Türschloss, insbesondere Kraftfahrzeugtürschloss, mit einer Antriebseinheit für ein Türschlosselement, wobei die Antriebseinheit wenigstens einen Antriebsmotor und zumindest zwei von diesem beaufschlagbare Wickelelemente zur Aufnahme (jeweiliger Enden) eines hierauf auf- und abwickelbaren Antriebsmittels aufweist.The invention relates to a door lock, in particular a motor vehicle door lock, with a drive unit for a door lock element, wherein the drive unit has at least one drive motor and at least two winding elements acted upon by the latter for receiving (respective ends) of a drive means which can be wound on and unwound therefrom.

Bei dem Türschlosselement handelt es sich um jedwedes Element eines üblichen Türschlosses bzw. Kraftfahrzeugtürschlosses, beispielsweise ein Element des Gesperres, der Betätigungshebelkette oder auch der Verriegelungshebelkette. Mit Hilfe der Antriebseinheit wird das fragliche Türschlosselement von einer ersten in eine zweite Funktionsstellung überführt, beispielsweise ein Verriegelungselement von der Position "entriegelt" in die Position "verriegelt". Die Antriebseinheit kann auch dafür sorgen, dass das fragliche Türschlosselement wieder seine ursprüngliche Stellung einnimmt. Darüber hinaus ist es natürlich auch denkbar, dass das Türschlosselement automatisch (beispielsweise gegen Federkraft) wieder in seine Ursprungsposition zurückkehrt, sobald die Antriebseinheit nicht mehr auf das Türschlosselement arbeitet.The door lock element is any element of a conventional door lock or motor vehicle door lock, for example an element of the locking mechanism, the actuating lever chain or the locking lever chain. With the help of the drive unit, the door lock element in question is transferred from a first to a second functional position, for example, a locking element from the position "unlocked" in the position "locked". The drive unit can also ensure that the door lock element in question resumes its original position. In addition, it is of course also conceivable that the door lock element automatically (for example, against spring force) returns to its original position when the drive unit is no longer working on the door lock element.

Derartige Antriebseinheiten werden im gattungsbildenen Stand der Technik nach der DE 10 2006 011 083 A1 eingesetzt, um die Geräuschentwicklung insgesamt zu verbessern. Aus diesem Grund ist bei der bekannten Lehre der Antriebsmotor über eine Zugmittelanordnung mit dem fraglichen Türschlosselement verbunden. Die Zugmittelanordnung verfügt über zwei Zugmittelabschnitte, die jeweils teilweise auf einer Antriebswelle des Antriebsmotors auf- und abwickelbar gestaltet sind. Dabei steht das freie Ende des einen Zugmittelabschnitts mit einer Eingriffstelle mit dem Türschlosselement in Eingriff und das freie Ende des anderen Zugmittelabschnitts steht an einer anderen Eingriffstelle ebenfalls mit dem Türschlosselement in Eingriff.Such drive units are in the generic state of the art according to the DE 10 2006 011 083 A1 used to improve overall noise. For this reason, in the known teaching, the drive motor is connected to the door lock element in question via a traction mechanism arrangement. The Zugmittelanordnung has two Zugmittelabschnitte, each of which is designed partly on a drive shaft of the drive motor and unwound. In this case, the free end of the one Zugmittelabschnitts with an engagement point with the door lock element is engaged and the free end of the other Zugmittelabschnitts is also at another engagement point with the door lock element into engagement.

Dadurch ist der Aufbau relativ kompliziert und Funktionsstörungen können grundsätzlich nicht ausgeschlossen werden. Zwar kennt man im Stand der Technik auch Ausführungsformen, die mit nur einem Wickelelement arbeiten, dann jedoch komplizierte Umlenkungsmaßnahmen für das Antriebsmittel erfordern, wie dies beispielsweise in der EP 1 536 090 A2 oder auch der DE 100 64 914 B4 der Fall ist. Hier will die Erfindung insgesamt Abhilfe schaffen.As a result, the structure is relatively complicated and malfunction can not be excluded in principle. Although known in the prior art, embodiments that work with only one winding element, but then require complicated deflection measures for the drive means, as for example in the EP 1 536 090 A2 or even the DE 100 64 914 B4 the case is. Here, the invention aims to provide a total remedy.

Der Erfindung liegt das technische Problem zugrunde, ein Türschloss der eingangs beschriebenen Ausgestaltung so weiter zu entwickeln, dass bei nochmals verbessertem Geräuschverhalten der erforderliche Bauraum für die Antriebseinheit verkleinert ist und zugleich eine kostengünstige und funktionssichere Variante zur Verfügung gestellt wird.The invention is based on the technical problem of further developing a door lock of the embodiment described above so that the required installation space for the drive unit is reduced again with improved noise behavior and at the same time a cost-effective and functionally reliable variant is made available.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßes Türschloss im Rahmen der Erfindung dadurch gekennzeichnet, dass zwischen die beiden Wickelelemente eine das Türschlosselement beaufschlagende Umlenkeinheit in das Antriebsmittel eingeschlauft ist.To solve this technical problem, a generic door lock in the invention is characterized in that between the two winding elements, a door lock element acting on deflection unit is run into the drive means.

Im Gegensatz zum Stand der Technik ist das flexible Antriebsmittel also nicht direkt - mittelbar oder unmittelbar - an das zu beaufschlagende Türschlosselement angeschlossen. Vielmehr erfolgt die Verbindung des Antriebsmittels mit dem fraglichen Türschlosselement über die angesprochene Umlenkeinheit. Hierdurch wird bereits eine nochmalige deutliche Verbesserung des Geräuschverhaltens erreicht. Denn die mit dem Türschlosselement verbundene Umlenkeinheit ist akustisch (durch das Antriebsmittel) von dem Antriebsmotor entkoppelt. Außerdem wird ein besonders kompakter Aufbau erreicht, weil die Umlenkeinheit üblicherweise nur an einem Anschlusspunkt an dem Türschlosselement angreift und nicht - wie bei der DE 10 2006 011 083 A1 - gleichsam zwei Anschlusspunkte realisiert sind. Vielmehr reicht es aus, wenn das Türschlosselement in diesem Anschlusspunkt mit Hilfe der erfindungsgemäßen Antriebseinheit beaufschlagt wird, um dann um seine Schwenkachse zu verschwenken und seine gewünschte (andere) Funktionsstellung einzunehmen. Dabei liegt es selbstverständlich im Rahmen der Erfindung, auch ein linear (beispielsweise gegen Federkraft) bewegbares Türschlosselement mit Hilfe der Umlenkeinheit zu beaufschlagen.In contrast to the prior art, the flexible drive means is therefore not directly - indirectly or directly - connected to the door lock element to be acted upon. Instead, the connection of the drive means with the door lock element in question takes place via the addressed deflection unit. As a result, a further significant improvement of the noise behavior is already achieved. Because the deflection unit connected to the door lock element is acoustically isolated (by the drive means) from the drive motor. In addition, a particularly compact structure is achieved because the deflection usually engages only at a connection point on the door lock element and not - as in the DE 10 2006 011 083 A1 - as it were realized two connection points. Rather, it is sufficient if the door lock element is acted upon in this connection point by means of the drive unit according to the invention, in order then to pivot about its pivot axis and to assume its desired (other) functional position. It is of course within the scope of the invention to apply a linear (for example against spring force) movable door lock element using the deflection unit.

Die beiden Wickelelemente können über den gleichen Wickeldurchmesser verfügen. In der Regel wird jedoch auf unterschiedliche Wickeldurchmesser zurückgegriffen. Auf diese Weise formen die beiden vom dem Antriebsmotor beaufschlagten Wickelelemente unterschiedlichen Wickeldurchmessers zusammen mit der in das Antriebsmittel eingeschlauften Umlenkeinheit einen Differentialseilzug. Dieser Differentialseilzug ist in der Lage, größere Kräfte auf das Türschlosselement zu übertragen, als dies der Antriebsmotor - ohne Übersetzung - erreichen würde. Mit anderen Worten können die beiden Wickelelemente erfindungsgemäß so ausgelegt werden, dass gleichzeitig eine Krafterhöhung der vom Antriebsmotor zur Verfügung gestellten Kraft an der Umlenkeinheit vorliegt bzw. beobachtet wird. Hierdurch lassen sich Antriebsmotoren geringer Antriebsleistung einsetzen, beispielsweise solche in Miniaturform, die klein bauen, wenig Strom benötigen und kostengünstig ausgeführt sind.The two winding elements can have the same winding diameter. As a rule, however, different winding diameters are used. In this way, the two winding elements acted upon by the drive motor of different winding diameter together with the deflection unit inserted into the drive means form a differential cable. This differential cable is able to transmit greater forces to the door lock element, as the drive motor - without translation - would achieve. In other words, the two winding elements can be designed according to the invention so that at the same time an increase in force of the force provided by the drive motor is present or observed at the deflection unit. As a result, low-power drive motors can be used, for example, those in miniature form, which build small, require little power and are designed inexpensively.

Die beiden Wickelelemente können als gleichachsige Wickeltrommeln ausgebildet sein. In diesem Fall sind die beiden Wickelelemente bzw. Wickeltrommeln meistens hintereinander direkt auf einer Welle des Antriebsmotors angeordnet. Dazu korrespondiert eine besonders kompakte und funktionssichere Bauform.The two winding elements may be formed as equiaxed winding drums. In this case, the two winding elements or winding drums are usually arranged one behind the other directly on a shaft of the drive motor. This corresponds to a particularly compact and reliable design.

Alternativ hierzu können die beiden Wickelelemente aber auch als voneinander beabstandete Wickelscheiben ausgeführt sein. Die beiden Wickelscheiben bzw. Wickelelemente sind regelmäßig und nicht notwendigerweise in einer gemeinsamen Wickelebene angeordnet. Bevorzugt verfügen sie über zwei jeweils senkrecht zu dieser Wickelebene angeordnete Achsen, die vorteilhaft parallel zueinander angeordnet sind. Um bei dieser Ausführungsform eine geringe Baugröße zu erreichen, hat es sich als günstig erwiesen, wenn die beiden Wickelelemente jeweils oder gemeinsam auf einem vom Antriebsmotor beaufschlagten Schneckenrad platziert sind. Für den Fall, dass zwei Schneckenräder realisiert sind, kann eine an die Welle des Antriebsmotors angeschlossene Antriebsschnecke zwischen die beiden Schneckenräder eintauchen und diese gemeinsam in Rotationen versetzen.Alternatively, however, the two winding elements can also be designed as spaced-apart winding discs. The two winding disks or winding elements are arranged regularly and not necessarily in a common winding plane. Preferably, they have two each Arranged perpendicular to this winding plane axes, which are advantageously arranged parallel to each other. In order to achieve a small size in this embodiment, it has proved to be advantageous if the two winding elements are placed in each case or together on a worm wheel acted upon by the drive motor. In the event that two worm wheels are realized, connected to the shaft of the drive motor drive worm between the two worm wheels dive and put them together in rotation.

Bei der Umlenkeinheit handelt es sich vorteilhaft um eine von dem Antriebsmittel umschlungene Umlenkscheibe. Diese Umlenkscheibe bzw. die Umlenkeinheit allgemein lässt sich unmittelbar an das Türschlosselement anschließen. In der Regel erfolgt jedoch ein mittelbarer Anschluss der Umlenkeinheit an das Türschlosselement, nämlich über ein Zwischenelement. Dabei kann als Zwischenelement grundsätzlich jedwedes Kraftübertragungselement zum Einsatz kommen, beispielsweise eine Stange, ein Seil oder dergleichen. - Bei dem flexiblen Antriebsmittel mag es sich ebenfalls um ein Seil, eine Kette, einen Riemen etc. handeln, welcher über die beiden Wickelelemente und die Umlenkeinheit geführt wird und geführt werden kann.The deflecting unit is advantageously a deflection disk wrapped around by the drive means. This deflection pulley or the deflection unit in general can be connected directly to the door lock element. As a rule, however, an indirect connection of the deflection unit to the door lock element takes place, namely via an intermediate element. In principle, any force transmission element can be used as the intermediate element, for example a rod, a cable or the like. - The flexible drive means may also be a rope, a chain, a belt, etc., which is guided over the two winding elements and the deflection and can be performed.

Im Ergebnis wird ein Türschloss, insbesondere ein Kraftfahrzeugtürschloss, zur Verfügung gestellt, welches sich zunächst einmal durch besondere akustische Vorzüge auszeichnet. Denn die jeweils in beispielsweise einem Schlosskasten gelagerten Elemente wie Antriebsmotor und Türschlosselement werden miteinander verbunden, und zwar ohne dass an dieser Stelle Körperschall übertragen werden kann. Hierfür sorgt einerseits das flexible Antriebsmittel und andererseits die von dem Antriebsmittel beaufschlagte Umlenkeinheit. Dabei wird insgesamt eine kompakte Bauform erreicht, welche sich in den gleichachsigen Wickeltrommeln oder den voneinander beabstandeten Wickelscheiben manifestiert, zwischen welche die gemeinsame Antriebsschnecke eintaucht.As a result, a door lock, in particular a motor vehicle door lock, provided, which is initially characterized by special acoustic benefits. Because each mounted in, for example, a lock case elements such as drive motor and door lock element are connected to each other, without that at this point structure-borne noise can be transmitted. On the one hand, this is ensured by the flexible drive means and, on the other hand, by the deflection unit acted upon by the drive means. In this case, a compact overall design is achieved, which manifests itself in the coaxial winding drums or the spaced-apart winding discs, between which dips the common drive screw.

Durch den optionalen Rückgriff auf unterschiedliche Wickeldurchmesser der beiden Wickelelemente kann darüber hinaus eine Kraftübersetzung realisiert werden. Dadurch lassen sich auch relativ leistungsschwache und folglich kleine und kostengünstige Antriebsmotoren einsetzen, wobei dennoch die Funktionalität gewährleistet ist und auch schwergängige Türschlosselemente sicher in ihre gewünschte Funktionsstellung überführt werden. Hierin sind die wesentlichen Vorteile zu sehen.By the optional recourse to different winding diameter of the two winding elements, a force transmission can be realized beyond. As a result, relatively low-power and consequently small and inexpensive drive motors can be used, yet the functionality is guaranteed and also stiff door lock elements are securely transferred to their desired functional position. Here are the main benefits.

In den Figuren ist ein Türschloss, vorliegend ein Kraftfahrzeugtürschloss dargestellt. Dieses Kraftfahrzeugtürschloss mag sich in einer Seitentür, Heckklappe, Kofferraumklappe oder dergleichen eines Kraftfahrzeuges befinden und wirkt in bekannter Art und Weise mit einem Schlosshalter an der zugehörigen Karosserie zur Darstellung eines Kraftfahrzeugtürverschlusses zusammen. Das Türschloss verfügt über einen lediglich in Fig. 1 angedeuteten Schlosskasten 1, in dem ein Gesperre 2, 3 gelagert sein mag. Das Gesperre 2, 3 setzt sich aus einer Drehfalle 2 und einer hiermit zusammenwirkenden Sperrklinke 3 zusammen. Im Rahmen des Ausführungsbeispiels und nicht einschränkend fungiert die Sperrklinke 3 als Türschlosselement 3, auf das eine Antriebseinheit 4 bis 9 arbeitet.In the figures, a door lock, in this case a motor vehicle door lock is shown. This motor vehicle door lock may be located in a side door, tailgate, boot lid or the like of a motor vehicle and cooperates in a known manner with a lock holder on the associated body for the representation of a motor vehicle door lock. The door lock has a merely in Fig. 1 indicated lock case 1, in which a locking mechanism 2, 3 may be stored. The locking mechanism 2, 3 is composed of a catch 2 and a pawl 3 cooperating therewith. In the context of the embodiment and not limiting acts the pawl 3 as a door lock element 3, on which a drive unit 4 to 9 operates.

Die Antriebseinheit 4 bis 9 setzt sich aus einem Antriebsmotor bzw. Elektromotor 4 und zumindest zwei von diesem beaufschlagbaren Wickelelementen 6, 7 zusammen. Die Wickelelemente 6, 7 dienen zur Aufnahme (jeweiliger Enden) eines hierauf auf- und abwickelbaren Antriebsmittels 8. Bei dem Antriebsmittel 8 handelt es sich im Rahmen der Darstellung und nicht einschränkend um ein Seil, einen Riemen oder dergleichen. Die Enden des flexiblen Antriebsmittels 8 sind jeweils an dem zugehörigen Wickelelement 6, 7 festgelegt (vgl. Fig. 1 bis 3) oder zu einem Kreis zusammengeführt (vgl. Fig. 4). Man erkennt, dass das flexible Antriebsmittel 8 in einer Schlaufe von dem einen Wickelelement 6 zum anderen Wickelelement 7 geführt ist. In diese Schlaufe bzw. in das Antriebsmittel 8 ist erfindungsgemäß eine Umlenkeinheit 9 eingeschlauft, und zwar zwischen die beiden Wickelelemente 6, 7. Das zu beaufschlagende Türschlosselement 3 ist an die Umlenkeinheit 9 angeschlossen. Das kann unmittelbar oder mittelbar über ein Zwischenelement 10 erfolgen.The drive unit 4 to 9 is composed of a drive motor or electric motor 4 and at least two of these can be acted upon winding elements 6, 7 together. The winding elements 6, 7 serve to receive (respective ends) of a drive means 8 which can be wound thereon and unwound. The drive means 8 is a rope, a belt or the like within the scope of illustration and not restrictively. The ends of the flexible drive means 8 are respectively fixed to the associated winding element 6, 7 (see. Fig. 1 to 3 ) or merged into a circle (cf. Fig. 4 ). It can be seen that the flexible drive means 8 is guided in a loop from one winding element 6 to the other winding element 7. In this loop or in the drive means 8 according to the invention a deflection unit 9 is running, between the two winding elements 6, 7. The door lock element 3 to be acted upon is connected to the deflection unit 9. This can be done directly or indirectly via an intermediate element 10.

Bei dem Zwischenelement 10 mag es sich um eine Verbindungsstange oder auch ein Verbindungsseil handeln, welches einerseits an eine Drehachse 11 der als Umlenkscheibe 9 ausgebildeten Umlenkeinheit 9 angeschlossen ist und andererseits an einen Anschlusspunkt 12 des Schlosselementes 3.The intermediate element 10 may be a connecting rod or else a connecting cable, which is connected on the one hand to an axis of rotation 11 of the deflecting unit 9 designed as a deflecting disk 9 and on the other hand to a connecting point 12 of the lock element 3.

Rotationen des Antriebsmotors 4 führen nun dazu, dass sich die Umlenkeinheit 9 entsprechend dem Doppelpfeil auf und nieder bewegt. Als Folge hiervon wird das Schlosselement 3 bzw. die Sperrklinke 3 um ihre Drehachse D bei einer Aufwärtsbewegung der Umlenkeinheit 9 im Gegenuhrzeigersinn entsprechend der angedeuteten Pfeilrichtung verschwenkt. Hierdurch kommt die Drehfalle 2 frei und kann (federunterstützt) ihre geöffnete Position einnehmen. Das heißt, im Rahmen des Ausführungsbeispiels wird die Antriebseinheit 4 bis 9 dazu genutzt, das Gesperre 2, 3 (elektrisch) zu öffnen. Das ist selbstverständlich nicht zwingend und nur als Beispiel zu sehen. Denn die Antriebseinheit 4 bis 9 könnte genauso gut dazu dienen, einen Verriegelungshebel von der Stellung "entriegelt" in die Position "verriegelt" zu überführen. Auch andere und vergleichbare Anwendungen im Kraftfahrzeugtürschloss sind denkbar und werden umfasst.Rotations of the drive motor 4 now cause the deflection unit 9 moves up and down according to the double arrow. As a result, the lock element 3 or the pawl 3 is pivoted about its axis of rotation D in an upward movement of the deflection unit 9 in the counterclockwise direction according to the indicated direction of the arrow. As a result, the catch 2 is released and can (spring assisted) take their open position. That is, in the embodiment, the drive unit 4 to 9 is added used to open the locking mechanism 2, 3 (electric). Of course this is not mandatory and can only be seen as an example. For the drive unit 4 to 9 could just as well serve to transfer a locking lever from the "unlocked" position to the "locked" position. Other and comparable applications in the motor vehicle door lock are conceivable and are included.

Die beiden Wickelelemente 6, 7 können über einen gleichen Wickeldurchmesser D1 und D2 verfügen. Vorteilhaft sind die zugehörigen Wickeldurchmesser D1 und D2 jedoch unterschiedlich gestaltet. Auf diese Weise formen die beiden Wickelelemente 6, 7 in Verbindung mit der in das Antriebsmittel 8 eingeschlauften Umlenkeinheit 9 einen Differentialseilzug. Dieser Differentialseilzug mag unmittelbar auf einer Welle 5 des Antriebsmotors 4 angeordnet sein (vgl. Fig. 1).The two winding elements 6, 7 may have a same winding diameter D 1 and D 2 . Advantageously, the associated winding diameter D 1 and D 2, however, designed differently. In this way, the two winding elements 6, 7 in conjunction with the inserted into the drive means 8 deflection unit 9 form a differential cable. This differential cable may be arranged directly on a shaft 5 of the drive motor 4 (see. Fig. 1 ).

Die unterschiedlichen Wickeldurchmesser D1 und D2 von einerseits dem Wickelelement 6 und andererseits dem Wickelement 7 führen dazu, dass die vom Antriebsmotor 4 auf die Welle 5 übertragene Kraft eine Übersetzung entsprechend dem Verhältnis D1/D2 erfährt. Hierdurch kann auf einen kleinbauenden Elektromotor als Antriebsmotor 4 zurückgegriffen werden.The different winding diameters D 1 and D 2 on the one hand the winding element 6 and on the other hand the Wickelement 7 cause that transmitted from the drive motor 4 to the shaft 5 force undergoes a translation corresponding to the ratio D 1 / D 2 . This can be used as a drive motor 4 on a small-sized electric motor.

In der Darstellung nach den Fig. 1 und 2 sind die Wickelelemente 6, 7 jeweils als gleichachsige Wickeltrommeln ausgeführt. Das heißt, beide Wickelelemente 6, 7 verfügen über die gleiche Drehachse, welche im Rahmen des Ausführungsbeispiels nach Fig. 1 mit der Welle 5 des Antriebsmotors 4 zusammenfällt. Dadurch wird eine besonders kompakte Bauform erreicht.In the illustration after the Fig. 1 and 2 the winding elements 6, 7 are each designed as equiaxed winding drums. That is, both winding elements 6, 7 have the same axis of rotation, which in the context of the embodiment according to Fig. 1 coincides with the shaft 5 of the drive motor 4. As a result, a particularly compact design is achieved.

Im Rahmen der Variante nach den Fig. 3 und 4 sind die beiden Wickelelemente 6, 7 als voneinander beabstandete Wickelscheiben ausgeführt. Die beiden Wickelscheiben liegen vorteilhaft - aber nicht notwendigerweise - in einer gemeinsamen Wickelebene, die im Wesentlichen mit der Zeichenebene in den Fig. 3 und 4 zusammenfällt. Senkrecht hierzu sind die jeweiligen Achsen der Wickelscheiben angeordnet, die parallel zueinander verlaufen mögen. Bei dieser Ausgestaltung taucht die Welle 5 des Antriebsmotors 4 zwischen die beiden Wickelelemente 6, 7 ein. Dazu sind die beiden Wickelelemente 6, 7 jeweils auf von dem Antriebsmotor 4 beaufschlagten Schneckenrädern 13 angeordnet. Beide Schneckenräder 13 werden in Übereinstimmung mit den Darstellungen nach den Fig. 3 und 4 von einer gemeinsamen und zwischen die beiden Schneckenräder 13 eintauchenden Antriebsschnecke 14 beaufschlagt, die ihrerseits auf der Welle 5 des Antriebsmotors 4 rotierend angeordnet ist. Es ist aber auch möglich, mit nur einem Schneckenrad 13 zu arbeiten, welches von der Antriebsschnecke 14 beaufschlagt wird. Das zeigt die Fig. 2. Dann sind beide Wickelelemente 6, 7 gleichachsig auf diesem einen Schneckenrad 13 angeordnet.As part of the variant after the Fig. 3 and 4 the two winding elements 6, 7 are designed as spaced-apart winding discs. The two winding disks are advantageous - but not necessarily - in one common winding plane, which is essentially in the plane of the drawing Fig. 3 and 4 coincides. Perpendicular to this, the respective axes of the winding disks are arranged, which may be parallel to each other. In this embodiment, the shaft 5 of the drive motor 4 between the two winding elements 6, 7 dives. For this purpose, the two winding elements 6, 7 are arranged in each case acted upon by the drive motor 4 worm wheels 13. Both worm wheels 13 are in accordance with the representations of the Fig. 3 and 4 from a common and between the two worm gears 13 immersed drive screw 14 is acted upon, which in turn is arranged on the shaft 5 of the drive motor 4 rotating. But it is also possible to work with only one worm wheel 13, which is acted upon by the drive worm 14. That shows that Fig. 2 , Then both winding elements 6, 7 coaxially arranged on this a worm wheel 13.

Die Umlenkeinheit 9 bzw. die Umlenkscheibe 9 wird von dem flexiblen Antriebsmittel 8 umschlungen. Um das Antriebsmittel 8 gegebenenfalls zu spannen, mag eine lediglich in Fig. 4 gezeigte Spannvorrichtung 15 realisiert sein. In diesem Fall sind die Enden des Antriebsmittels 8 nicht an den jeweiligen Wickelelementen 6, 7 angebracht, sondern wird das Antriebsmittel 8 gleichsam im Kreis zwischen einerseits der Spannvorrichtung 15 und andererseits der Umlenkeinheit 9 geführt. Von dem kreisförmig verlaufenden Antriebsmittel 8 werden in diesem Fall der Antriebsmotor 4, seine Welle 5 und die Antriebsschnecke 14 umschlossen.The deflection unit 9 or the deflection plate 9 is looped around by the flexible drive means 8. In order to tension the drive means 8, if necessary, a merely in Fig. 4 be shown jig 15 realized. In this case, the ends of the drive means 8 are not attached to the respective winding elements 6, 7, but the drive means 8 is guided as it were in a circle between on the one hand the tensioning device 15 and on the other hand the deflection unit 9. Of the circular drive means 8, the drive motor 4, its shaft 5 and the drive worm 14 are enclosed in this case.

Um das Antriebsmittel 8 hin- und herzubewegen und die erforderlichen Stellbewegungen an der Umlenkeinheit 9 zu erzeugen, ist das Antriebsmittel 8 jeweils ein- oder mehrfach um die Wickelelemente 6, 7 geschlungen. Für den Antrieb der Wickelelemente 6, 7 sorgt wiederum der Antriebsmotor 4 über die Antriebsschnecke 14, welche mit zugehörigen und die Wickelelemente 6, 7 tragenden Schneckenrädern 13 kämmt.In order to move the drive means 8 back and forth and to generate the required actuating movements on the deflection unit 9, the drive means 8 is wound one or more times around the winding elements 6, 7. For the drive of the winding elements 6, 7, in turn, the drive motor 4 via the drive screw 14, which meshes with associated and the winding elements 6, 7 supporting worm wheels 13.
