  • an inner coupling part, which is rotatably mounted about an axis of rotation,

  • a coupling ring, which encompasses the coupling parts,

Kopplungsmechanismen für mechatronische Schließsysteme ermöglichen das Öffnen einer Öffnung, etwa einer Tür, nach einer positiven Authentifizierung eines Benutzers. Die Öffnung kann nach positiver Authentifizierung durch die Betätigung einer üblichen Betätigungshandhabe erfolgen, wobei die Betätigungsbewegung als Drehbewegung über einen Vierkant auf das innere Kopplungsteil übertragen werden kann. Die Authentifizierung kann beispielsweise durch die Erkennung eines Codes in Form eines Schlüssels, einer Karte, durch eine biometrische Erkennungseinheit oder durch eine Kombination mehrerer Authentifizierungsarten erfolgen. Eine Panikfunktion, bei der die Öffnung von der Innenseite der Tür immer möglich ist, kann ebenfalls umgesetzt werden, da der Kopplungsmechanismus bevorzugt nur die Betätigungshandhabe auf der Außenseite einer Tür mit der Schließbetätigung koppelt, beziehungsweise entkoppelt und die Betätigungshandhabe auf der Innenseite der Tür davon unberücksichtigt bleibt.Coupling mechanisms for mechatronic locking systems allow an opening, such as a door, to be opened after positive user authentication. After positive authentication, the opening can take place by actuating a conventional actuating handle, in which case the actuating movement can be transmitted to the inner coupling part as a rotary movement via a square. The authentication can take place, for example, by recognizing a code in the form of a key, a card, by a biometric recognition unit or by a combination of several types of authentication. A panic function, in which opening from the inside of the door is always possible, can also be implemented, since the coupling mechanism preferably only couples the actuating handle on the outside of a door to the closing actuation, or decouples it and disregards the actuating handle on the inside of the door remains.

Ein solcher Kopplungsmechanismus ist aus der DE 20 2005 021 315 U1 bekannt. Bei der bekannten Kopplungseinrichtung wird ein Kopplungsring zum Entkoppeln der Kopplungsteile gegen eine Federkraft in Richtung der Drehachse verschoben. Bei diesem Aufbau ist eine vergrößerte Bauhöhe in Richtung der Drehachse erforderlich. Da diese mechatronischen Schließsysteme bevorzugt für die Montage auf einem Türblatt vorgesehen sind, ist eine flachere, kompakte Bauweise wünschenswert. Der mehrteilige Aufbau der elastischen Übertragungsstäbe für die Übertragung des Kraftflusses von dem Motor ist aufwendig gestaltet und durch die nahezu senkrechte Ausrichtung der von der Drehachse abstehenden Übertragungsstäbe zueinander wird ein großer Bauraum benötigt.Such a coupling mechanism is from DE 20 2005 021 315 U1 known. In the known coupling device, a coupling ring is used for decoupling the coupling parts shifted against a spring force in the direction of the axis of rotation. With this structure, an increased overall height in the direction of the axis of rotation is required. Since these mechatronic locking systems are preferably intended for installation on a door leaf, a flatter, more compact design is desirable. The multi-part structure of the elastic transmission rods for the transmission of the power flow from the engine is complex and the almost vertical alignment of the transmission rods projecting from the axis of rotation to one another requires a large amount of space.

Die WO 2004 099 537 A1 offenbart ein Schloss für eine Tür mit einer Betätigungsmitteln zur Betätigung eines Riegels und einer Sicherungseinrichtung zur Sicherung einer Verriegelungsposition des Riegels, wobei die Verriegelungsposition ein Kopplungselement zum Herstellen oder Unterbrechen einer Kopplung zwischen den Betätigungsmitteln und dem Riegel aufweist. Das Kopplungselement kann unabhängig von der Position der Betätigungseinrichtung aktiviert werden. Dazu nimmt ein motorisch verschiebbares, ringförmiges Federelement ein äußeres Kopplungsteil auf und umschließt ein inneres Kopplungsteil.The WO 2004 099 537 A1 discloses a lock for a door with an actuating means for actuating a bolt and a safety device for securing a locking position of the bolt, the locking position having a coupling element for establishing or breaking a coupling between the actuating means and the bolt. The coupling element can be activated independently of the position of the actuating device. For this purpose, a motor-driven, ring-shaped spring element accommodates an outer coupling part and encloses an inner coupling part.

Aus der nicht vorveröffentlichten WO 2020 055 851 A1 ist ein elektronische Verriegelungseinrichtung bekannt, be der durch einen motorisch in Längsrichtung verschiebbaren Stift ein äußeres, ringförmiges Kupplungsteil mit einem inneren Kupplungsteil koppelbar ist.From the unpublished WO 2020 055 851 A1 an electronic locking device is known in which an outer, ring-shaped coupling part can be coupled to an inner coupling part by a pin that can be moved in the longitudinal direction by a motor.

Aus der EP 2 431 557 A1 ist ein Kopplungsmechanismus bekannt, bei dem eine motorisch angetriebene Spindel eine um eine Drehachse bewegbare Torsionsfeder zum Antrieb eines Kopplungsschiebers bewegt. Bei der nahezu senkrechten Ausrichtung der von der Drehachse abstehenden Übertragungsstäbe der Torsionsfeder zueinander wird ein großer Bauraum benötigt, da ein Versatz der Anordnung des Motors zur Längserstreckung des Kopplungsschiebers erforderlich ist.From the EP 2 431 557 A1 a coupling mechanism is known in which a motor-driven spindle moves a torsion spring movable about an axis of rotation to drive a coupling slide. When the transmission rods of the torsion spring, which protrude from the axis of rotation, are aligned almost perpendicularly to one another, a large amount of space is required, since the arrangement of the motor must be offset relative to the longitudinal extent of the coupling slide.

Des Weiteren ist aus der EP 3 272 976 A1 ein Kopplungsmechanismus für ein mechatronisches Schließsystem bekannt, bei dem ein Motor über ein Zahnradgetriebe eine Federsteuerung für ein Kopplungszwischenstück antreibt, an dem ein Kopplungselement zwangsgeführt und zu beiden Seiten verschwenkbar angeordnet ist, da das Kopplungszwischenstück sich zur beiden Seiten erstreckende, bogenförmige Gleitschienen für das Kopplungselement aufweist. Diese bogenförmigen Gleitschienen sind außerhalb eines äußeren Kopplungsteils angeordnet und erfordern daher für eine funktionssichere Bauweise einen großen Bauraum. Da die Motor-/Getriebeeinheit versetzt zu den Kopplungsteilen angeordnet ist, steht dieser Aufbau einer kompakten Bauweise ebenfalls entgegen.Furthermore, from the EP 3 272 976 A1 a coupling mechanism for a mechatronic locking system is known, in which a motor via a gear train drives a spring control for a coupling element, on which a coupling element is forcibly guided and pivotable on both sides, since the coupling element has arc-shaped slide rails for the coupling element extending on both sides . These arcuate slide rails are arranged outside of an outer coupling part and therefore require a functionally reliable Construction a large space. Since the motor/gear unit is arranged offset to the coupling parts, this structure also stands in the way of a compact design.

Aus der EP 1 881 135 A1 ist ein Kopplungsmechanismus bekannt, bei dem eine Wippe zwischen einem Motor und einem Sperrelement angeordnet ist. Die Wippe ist schwenkbar gelagert und von einem Federelement vorgespannt. Die Wippe liegt mit einem freien Ende an einem Anschlag an. Die motorische Bewegung des Sperrelements entgegen der Federkraft erfordert einen hohen Kraftaufwand. Dies erfordert eine andere Auslegung der Bauteile und einen erhöhten Energieaufwand.From the EP 1 881 135 A1 a coupling mechanism is known in which a rocker is arranged between a motor and a locking element. The rocker is pivoted and preloaded by a spring element. The rocker rests against a stop with a free end. The motorized movement of the blocking element against the spring force requires a great deal of effort. This requires a different design of the components and an increased energy consumption.

Es liegt die Aufgabe zugrunde, einen möglichst kompakten und gleichzeitig funktionssicheren und leichtgängigen Kopplungsmechanismus für ein mechatronisches Schließsystem zu entwickeln.The underlying task is to develop a coupling mechanism for a mechatronic locking system that is as compact as possible and at the same time functionally reliable and smooth-running.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Kopplungsring in einer umlaufenden Nut am äußeren Kopplungsteil geführt ist. Durch die geschlossene Form des Kopplungsrings ist diese Baueinheit besonders stabil aufgebaut. Die ausschließliche Bewegbarkeit des Kopplungsrings und des Kopplungselements entlang einer zur Drehachse senkrechten Achse ermöglichen eine sehr flache Bauweise des Kopplungsmechanismus. Dies ermöglicht die Verwendung eines sehr flachen, nur wenig von einem Türblatt abstehenden Gehäuses, so dass die aus dem Gehäuse herausstehende Betätigungshandhabe nicht im besonderen Maße von dem Türblatt beabstandet ist. Dadurch, dass der Kopplungsring in einer umlaufenden Nut am äußeren Kopplungsteil geführt ist, ist der Aufbau besonders stabil und sicher. Dies sorgt für eine sehr stabile, weitestgehend umlaufende Führung. Ein Bewegen des Kopplungsrings aus der Führung ist durch den ringförmigen Aufbau ausgeschlossen.The object is achieved according to the invention in that the coupling ring is guided in a circumferential groove on the outer coupling part. Due to the closed form of the coupling ring, this unit is particularly stable. The exclusive movability of the coupling ring and the coupling element along an axis perpendicular to the axis of rotation enables a very flat design of the coupling mechanism. This allows the use of a very flat housing that protrudes only slightly from a door leaf, so that the actuating handle protruding from the housing is not particularly spaced from the door leaf. Because the coupling ring is guided in a circumferential groove on the outer coupling part, the structure is particularly stable and safe. This ensures a very stable, largely circumferential guide. The annular structure prevents the coupling ring from moving out of the guide.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Aufbau besonders einfach und kompakt, wenn das Kopplungselement ein separates Bauteil ist und im äußeren Kopplungsteil auf der Ebene des Kopplungsrings entlang einer zur Drehachse senkrechten Achse bewegbar geführt ist und in der ersten Position mit beiden Enden nicht aus der Führung im äußeren Kopplungsteil hinaussteht und in der zweiten Position zur Bewegungskopplung zwischen dem inneren und dem äußeren Kopplungsteil angeordnet ist. Dabei ist die erste Position die ausgekuppelte Position, bei der die beiden Kopplungsteile nicht miteinander drehverbunden sind und die zweite Position ist die eingekuppelte Position, bei der das Kopplungselement beide Kopplungsteile miteinander verbindet. Da das Kopplungselement ein separates Bauteil ist, kann es gegenüber dem Kopplungsring verdrehbar angeordnet sein, damit auch in einer Verdrehstellung der beiden Kopplungsteile, etwa bei gedrückter Betätigungshandhabe, das Kopplungselement in die erste und die zweite Position bewegbar ist. Die Bewegung des Kopplungselements erfolgt in einer Richtung durch die Schiebebewegung des Kopplungsrings und kann in der anderen Richtung beispielsweise durch die Schwerkraft erfolgen. Eine unterstützende Federkraft ist dadurch nicht erforderlich.According to an advantageous development of the invention, the structure is particularly simple and compact if the coupling element is a separate component and is movably guided in the outer coupling part at the level of the coupling ring along an axis perpendicular to the axis of rotation and in the first position with both ends not out of the Guide protrudes in the outer coupling part and is arranged in the second position for movement coupling between the inner and the outer coupling part. The first position is the disengaged position, in which the two coupling parts are not rotationally connected to one another, and the second position is the engaged position, in which the coupling element both Coupling parts connected to each other. Since the coupling element is a separate component, it can be arranged such that it can be rotated relative to the coupling ring, so that the coupling element can be moved into the first and second position even when the two coupling parts are in a rotated position, for example when the actuating handle is pressed. The movement of the coupling element takes place in one direction by the sliding movement of the coupling ring and can take place in the other direction, for example by gravity. A supporting spring force is therefore not required.

Der Aufbau des Kopplungsmechanismus ist gemäß einer vorteilhaften Weiterbildung der Erfindung besonders kompakt und einfach, wenn das Kopplungselement an der dem Antrieb zugewandten Innenseite des Kopplungsrings angeordnet ist. Bei der Anordnung des Antriebs unterhalb der Kopplungsteile kann das Kopplungselement somit durch den Antrieb entgegen der Schwerkraft in die zweite, eingekuppelte Position verschoben werden und bewegt sich nach dem Zurückbewegen des Antriebs in die erste, ausgekuppelte Position selbstständig zurück. Der Aufbau ist besonders einfach ausgeführt, wenn in der Verlängerung des zur Mitte des Kopplungsrings zeigenden Endes des Kopplungselements zunächst ein Zwischenstift und anschließend ein Steuerstift längsverschieblich geführt angeordnet sind, wobei die Länge des Zwischenstifts dem Durchmesser des inneren Kopplungsteils entspricht und die Länge des Steuerstifts der Ringstärke des äußeren Kopplungsteils entspricht, wobei die Gesamtlänge des Kopplungselements, des Zwischenstifts und des Steuerstifts dem inneren Durchmesser des Kopplungsrings in einem Bewegungsbereich entspricht. Somit bewirkt eine Verschiebung des Kopplungsrings immer auch eine Verschiebung des Kopplungselements, egal, in welche Richtung der Kopplungsring verschoben wird. Weitere Aktoren, wie ein weiterer Motorantrieb oder eine zusätzliche Feder, können entfallen, daher ist der Aufbau besonders kompakt und einfach. Auch der Antrieb kann entsprechend kleiner dimensioniert werden, da er nicht gegen eine Federkraft arbeiten muss, um die Feder zur Kraftspeicherung für die Rückbewegung vorzuspannen.According to an advantageous development of the invention, the structure of the coupling mechanism is particularly compact and simple if the coupling element is arranged on the inside of the coupling ring facing the drive. When the drive is arranged below the coupling parts, the coupling element can thus be displaced by the drive against the force of gravity into the second, engaged position and moves back automatically into the first, disengaged position after the drive has been moved back. The design is particularly simple if, in the extension of the end of the coupling element pointing towards the center of the coupling ring, first an intermediate pin and then a control pin are arranged in a longitudinally displaceable manner, with the length of the intermediate pin corresponding to the diameter of the inner coupling part and the length of the control pin corresponding to the ring thickness of the outer coupling part, wherein the total length of the coupling member, the intermediate pin and the control pin corresponds to the inner diameter of the coupling ring in a range of movement. Thus, a displacement of the coupling ring always causes a displacement of the coupling element, regardless of the direction in which the coupling ring is displaced. Additional actuators, such as an additional motor drive or an additional spring, can be omitted, so the structure is particularly compact and simple. The drive can also be made correspondingly smaller, since it does not have to work against a spring force in order to prestress the spring for storing energy for the return movement.

Der Kopplungsmechanismus ist weiterhin besonders einfach und sicher aufgebaut, wenn an den Enden des Bewegungsbereichs Anschläge für das Kopplungselement vorgesehen sind. Die Anschlage sind an der Innerseite des Kopplungsrings angeordnet und begrenzen auf einfache Weise den Bewegungsbereich der Betätigungshandhabe. Durch die Anordnung der Anschläge an beiden Enden des Bewegungsbereichs ist eine Verwendung für linksseitig und rechtsseitig angeschlagene Türen möglich, ebenso kann die Betätigungshandhabe, wie bei bestimmten Anwendungen erforderlich, auch aus der horizontalen Position nach oben gezogen werden.Furthermore, the coupling mechanism is constructed in a particularly simple and safe manner if stops for the coupling element are provided at the ends of the movement range. The stops are arranged on the inside of the coupling ring and limit the range of movement of the actuating handle in a simple manner. By arranging the stops at both ends of the range of motion, use for doors hinged on the left and right is possible required for certain applications, can also be pulled up from the horizontal position.

Gemäß einer nächsten vorteilhaften Weiterbildung wird die korrekte Funktionsweise zusätzlich sichergestellt, wenn der Kopplungsring ein entlang einer zur Drehachse senkrechten Achse nach außen gerichtetes Führungsteil aufweist, welches in dem den Kopplungsmechanismus umgebenden Gehäuse verschiebbar geführt ist.According to a next advantageous development, the correct functioning is additionally ensured if the coupling ring has a guide part which is directed outwards along an axis perpendicular to the axis of rotation and which is displaceably guided in the housing surrounding the coupling mechanism.

Dadurch wird ein verdrehen des Kopplungsrings in der umlaufenden Nut am äußeren Kopplungsteil sicher verhindert und nur eine reine Schiebebewegung ermöglicht.This reliably prevents the coupling ring from twisting in the circumferential groove on the outer coupling part and only allows a pure sliding movement.

Der Aufbau ist weiterhin besonders einfach und kompakt, wenn das Führungsteil eine Koppeleinrichtung mit dem Antrieb aufweist. Das Führungsteil führt somit nicht nur den Kopplungsring in der gewünschten Schiebebewegung, sondern erfüllt mit der Koppeleinrichtung gleichzeitig die Funktion des Bindeglieds zur Kraftübertragung von dem Antrieb zur Schiebebewegung des Kopplungsrings. Die Koppeleinrichtung kann eine einfache Bohrung für ein Schenkelende eines Federdrahts sein, wobei sich der Durchmesser des Durchgangslochs idealerweise zur Lochmitte hin von beiden Seiten verjüngt, um eine bessere Führung für das Schenkelende zu erzielen und um die Reibung zu verringern.The structure is also particularly simple and compact if the guide part has a coupling device with the drive. The guide part thus not only guides the coupling ring in the desired sliding movement, but also fulfills the function of the connecting link for power transmission from the coupling device at the same time Drive for the sliding movement of the coupling ring. The coupling device can be a simple bore for a leg end of a spring wire, the diameter of the through hole ideally tapering towards the center of the hole on both sides in order to achieve better guidance for the leg end and to reduce friction.

Die Montage des Kopplungsmechanismus gestaltet sich besonders einfach, wenn der Kopplungsring zweiteilig ausgeführt ist und beide Teile formschlüssig koppelbar sind. Der eine Teil des Kopplungsrings wird dabei in die umlaufende Nut eingesetzt und der andere Teil des Kopplungsrings kann idealerweise über einen in einem Abschnitt weniger hohe Wandung der Nut zugeführt und mit dem anderen Teil gekoppelt werden. Die Kopplung erfolgt idealerweise durch korrespondierende Formschlusselemente an den Enden beider Teile, welche sich beim Zuführen des anderen Teils des Kopplungsrings fügen.The assembly of the coupling mechanism is particularly simple if the coupling ring is made in two parts and both parts can be coupled in a form-fitting manner. One part of the coupling ring is inserted into the circumferential groove and the other part of the coupling ring can ideally be fed to the groove via a wall that is less high in one section and coupled to the other part. The coupling is ideally effected by corresponding form-fitting elements at the ends of both parts, which join when the other part of the coupling ring is fed in.

Nach der Freigabe des inneren Kopplungsteils gegenüber dem äußeren Kopplungsteils ist das Verdrehen gegeneinander besonders einfach, wenn die Enden des Kopplungselements, des Zwischenstifts und des Steuerstifts zumindest teilweise angefast oder abgerundet sind. Die bearbeiteten Kanten sorgen für eine leichtgängige und prozesssichere Betätigung des Kopplungsmechanismus.After the inner coupling part has been released from the outer coupling part, twisting relative to one another is particularly easy if the ends of the coupling element, the intermediate pin and the control pin are at least partially chamfered or rounded. The machined edges ensure smooth and process-reliable actuation of the coupling mechanism.

Der Kopplungsmechanismus kann besonders kompakt gestaltet werden, wenn der Antrieb, welcher den Kopplungsring von einer ersten Position in eine zweite Position und von der zweiten Position in die erste Position bewegt, aus einem Motor und einem Getriebe besteht, wobei das Getriebe die Bewegung über eine helixförmige Schnecke und einen schwenkbar gelagerten, einstückigen Federdraht mit jeweils einem von der Schwenkachse entfernten Schenkelende auf das Führungsteil überträgt. Insbesondere durch den Federdraht kann die Bewegung einfach und direkt oder umgelenkt übertragen werden. Der Federdraht kann durch leichte Verformung Belastungsspitzen aufnehmen. Dies führt zu einer Entlastung aller weiteren Bauteile. Der Gehäuseteil für den Antrieb kann schmaler ausgeführt werden als der Gehäuseteil für die Kopplungsteile. Der Motor ist idealerweise ein Elektromotor.The coupling mechanism can be made particularly compact if the drive, which moves the coupling ring from a first position to a second position and from the second position to the first position, consists of a motor and a gear, the gear making the movement via a helical Worm and a pivotally mounted, one-piece spring wire, each with a leg end remote from the pivot axis, are transferred to the guide part. In particular, the spring wire can be used to transmit the movement simply and directly or in a deflected manner. The spring wire can absorb peak loads by slightly deforming it. This relieves all other components. The housing part for the drive can be made narrower than the housing part for the coupling parts. The motor is ideally an electric motor.

Der Antrieb des Kopplungsmechanismus ist sehr kompakt, wenn der Winkel zwischen den Schenkelenden, ausgehend von der Schwenkachse, kleiner 75° ist. Dadurch kann die helixförmige Schnecke sehr nahe an der Koppeleinrichtung positioniert werden. Dabei sind der Motor und die Schnecke parallel übereinander über dem Führungsteil und quer zur Verschieberichtung des Führungsteils angeordnet.The drive of the coupling mechanism is very compact if the angle between the leg ends, starting from the pivot axis, is less than 75°. This allows the helical screw to be positioned very close to the coupling device. In this case, the motor and the worm are arranged parallel one above the other above the guide part and transversely to the displacement direction of the guide part.

Figur 1 zeigt einen erfindungsgemäßen Kopplungsmechanismus mit geöffnetem Gehäuse 8. Durch den Verzicht auf den Gehäusedeckel sind die einzelnen Bauteile gut sichtbar. Der Kopplungsmechanismus wird üblicherweise auf einem Türblatt montiert. In dem oberen Teil des Gehäuses 8 ist ein Antrieb 6 angeordnet. Ein horizontal eingebauter Motor 16 überträgt die Bewegung über ein Getriebe 17 auf einen Kopplungsring 4. Das Getriebe 17 besteht aus Zahnrädern, die den Motor 16 mit einer parallel unterhalb angeordneten helixförmigen Schnecke 18 verbinden. In dem Schneckengang ist ein Schenkelende 20 eines um eine Schwenkachse 21 drehbar gelagerten Federdrahts 19 geführt. Durch die Drehbewegung des Federdrahtes 19 wird ein mit dem Kopplungsring 4 bewegungsgekoppeltes Führungsteil 9 in vertikaler Richtung verschieblich bewegt. Der Kopplungsring 4 umgreift ein inneres Kopplungsteil 1 und ein äußeres Kopplungsteil 3, wobei die Kopplungsteile 1, 3 drehbeweglich um die Drehachse 2 angeordnet sind und jeweils eine Vierkantaufnahme für einen Verbindungsvierkant für die Verbindung mit einer nicht dargestellten Betätigungshandhabe einer Tür oder dergleichen aufweist. Das innere Kopplungsteil 1 ist dabei bevorzugt für die auf der Außenseite der Tür angeordneten Betätigungshandhabe vorgesehen, da diese Seite üblicherweise zum Schutz vor unberechtigtem Zutritt von der Betätigung des Türschlosses entkoppelbar gestaltet werden soll. Dieses bewirkt der erfindungsgemäße Kopplungsmechanismus. figure 1 shows a coupling mechanism according to the invention with the housing 8 open. By dispensing with the housing cover, the individual components are clearly visible. The coupling mechanism is usually mounted on a door leaf. In the upper part of the housing 8, a drive 6 is arranged. A horizontally installed motor 16 transmits the movement via a gear 17 to a coupling ring 4. The gear 17 consists of gear wheels which connect the motor 16 to a helical worm 18 arranged parallel below. A limb end 20 of a spring wire 19 rotatably mounted about a pivot axis 21 is guided in the worm thread. Due to the rotary movement of the spring wire 19, a guide part 9, which is movement-coupled to the coupling ring 4, is displaceably moved in the vertical direction. The coupling ring 4 encompasses an inner coupling part 1 and an outer coupling part 3, the coupling parts 1, 3 being arranged to be rotatable about the axis of rotation 2 and each having a square socket for a connecting square for connection to an operating handle (not shown) of a door or the like. The inner coupling part 1 is preferred for those arranged on the outside of the door Actuating handle provided because this page is usually to be designed decoupled to protect against unauthorized access from the operation of the door lock. This is brought about by the coupling mechanism according to the invention.

Alle Bauteile des Antriebs 6 sind direkt in einem Gehäuse 8 befestigt oder befinden sich zumindest teilweise als bauliche Einheit auf einer nicht dargestellten Platine, die in das Gehäuse 8 eingesetzt werden kann.All components of the drive 6 are fastened directly in a housing 8 or are at least partially located as a structural unit on a circuit board, not shown, which can be inserted into the housing 8 .

Figur 2 zeigt zur Verdeutlichung den erfindungsgemäßen Kopplungsmechanismus aus Fig. 1 ohne Gehäuse 8, Vierkantbolzen und innerem Kopplungsteil 1. Gut erkennbar ist der kompakte Aufbau des Antriebs 6, mit dem horizontal eingebauten Motor 16, der parallel unterhalb dazu angeordneten helixförmigen Schnecke 18 und dem Federdraht 19. Das Schenkelende 22 des um die Schwenkachse 21 drehbar gelagerten Federdrahts 19 greift in eine Koppeleinrichtung 10 im Führungsteil 9 ein. Die Koppeleinrichtung 10 kann ein einfaches Durchgangsloch sein, wobei sich der Durchmesser des Durchgangslochs idealerweise zur Lochmitte hin von beiden Seiten verjüngt, um eine bessere Führung für ein Schenkelende 22 zu erzielen und um Reibung zu verringern. Der von dem Führungsteil 9 bewegte Kopplungsring 4 ist im drehbeweglich um die Drehachse 2 gelagerten äußeren Kopplungsteil 3 aufgenommen und steuert ein Kopplungselement 5 und einen in dessen weiteren Längserstreckung angeordneten Zwischenstift 11. figure 2 shows the coupling mechanism according to the invention for clarification 1 without housing 8, square bolt and inner coupling part 1. The compact design of the drive 6, with the horizontally installed motor 16, the helical worm 18 arranged parallel below it and the spring wire 19 is clearly visible Spring wire 19 engages in a coupling device 10 in the guide part 9 . The coupling device 10 can be a simple through hole, with the diameter of the through hole ideally tapering towards the center of the hole from both sides in order to achieve better guidance for a leg end 22 and to reduce friction. The coupling ring 4 moved by the guide part 9 is accommodated in the outer coupling part 3, which is mounted so that it can rotate about the axis of rotation 2, and controls a coupling element 5 and an intermediate pin 11 arranged in its further longitudinal extent.

Figur 3 zeigt den erfindungsgemäßen Kopplungsmechanismus aus Fig. 2 ohne Antrieb in einer gedrehten Position. Durch die Drehung ist die Nut 7 in dem äußeren Kopplungsteil 3 ersichtlich, die im unteren Teil einen abgesetzten Bereich 24 für die Montage des zweigeteilten Kopplungsrings 4 aufweist. Bei der Montage kann der obere Teil des Kopplungsrings 4 einfach aus der Richtung senkrecht zur Drehachse 2 eingesetzt werden. Der abgesetzte Bereich 24 weist auf einer Seite der Wandung einer Nut 7 eine geringere Höhe auf, so dass der Durchmesser des äußeren Kopplungsteils 3 in diesem abgesetzten Bereich 24 kleiner ist. figure 3 shows the coupling mechanism according to the invention 2 unpowered in a rotated position. The rotation reveals the groove 7 in the outer coupling part 3, which has a recessed area 24 for the assembly of the two-part coupling ring 4 in the lower part. When assembling, the upper part of the coupling ring 4 can be easily inserted from the direction perpendicular to the axis of rotation 2 . The stepped area 24 has a smaller height on one side of the wall of a groove 7, so that the diameter of the outer coupling part 3 is smaller in this stepped area 24.

Figur 4 zeigt den erfindungsgemäßen Kopplungsmechanismus aus Fig. 3 ohne das äußere Kopplungsteil 3. Der zweigeteilte Kopplungsring 4 schließt die in der Längserstreckung hintereinander angeordneten Bauteile Kopplungselement 5, Zwischenstift 11 und einen Steuerstift 12 ein. Diese drei Bauteile weisen eine gemeinsame Länge auf, die dem inneren Durchmesser des Kopplungsrings 4 im Bewegungsbereich 13 für das Kopplungselement 5 entspricht. Der Bewegungsbereich 13 ist zu beiden Seiten begrenzt durch Anschläge 14, 15 für das Kopplungselement 5. Durch die Zweiteilung des Kopplungsrings 4 kann der untere Teil des Kopplungsrings 4 für eine einfache Montage aus Richtung der Drehachse 2 in die mit dem oberen Teil des Kopplungsrings 4 korrespondierenden Formschlussflächen 23 eingesetzt werden. figure 4 shows the coupling mechanism according to the invention 3 without the outer coupling part 3. The two-part coupling ring 4 encloses the components coupling element 5, intermediate pin 11 and a control pin 12 arranged one behind the other in the longitudinal extension. These three components have a common length that corresponds to the inner diameter of the coupling ring 4 in the area of movement 13 for the coupling element 5 . The range of motion 13 is limited on both sides by stops 14, 15 for the coupling element 5. Due to the division of the coupling ring 4, the lower part of the coupling ring 4 can be inserted into the form-fitting surfaces 23 corresponding to the upper part of the coupling ring 4 for simple assembly from the direction of the axis of rotation 2.

Figur 5 zeigt das erfindungsgemäße äußere Kopplungsteil 3 aus Fig. 3 in einer weiter gedrehten Position. Ersichtlich ist die umlaufende Nut 7 mit dem abgesetzten Bereich 24, der sich annähernd über den halben Umfang der Nut 7 erstreckt. figure 5 shows the outer coupling part 3 according to the invention 3 in a more rotated position. The circumferential groove 7 with the stepped area 24, which extends approximately over half the circumference of the groove 7, can be seen.
