Ein Schloss für ein Kraftfahrzeug oder ein Gebäude weist ein Gesperre auf, welches eine verschwenkbare Drehfalle und wenigstens eine verschwenkbare Sperrklinke für ein Verrasten der Drehfalle umfasst. Ein solches Schloss dient zum zeitweisen Verschließen von Öffnungen in Kraftfahrzeugen oder Gebäuden mit Hilfe von Türen oder Klappen. Im geschlossenen Zustand eines solchen Schlosses greift die Drehfalle um den in der Regel bügelförmig ausgeführten Schließbolzen - auch Schlosshalter genannt - herum, der im Fall eines Kraftfahrzeugs meistens an der Karosserie befestigt ist. Erreicht die Drehfalle durch ein Verschwenken ausgehend von einer geöffneten Stellung eine Schließstellung, so wird die Drehfalle schließlich mittels der Sperrklinke verrastet. Dann kann die Drehfalle nicht mehr in Richtung geöffnete Stellung zurück gedreht werden und der Schließbolzen das Gesperre nicht mehr verlassen. Für ein Öffnen ist es erforderlich, die Sperrklinke aus der Raststellung heraus zu bewegen.A lock for a motor vehicle or a building has a locking mechanism, which comprises a pivotable rotary latch and at least one pivotable pawl for locking the rotary latch. Such a lock is used for temporary closing of openings in motor vehicles or buildings by means of doors or flaps. In the closed state of such a lock, the rotary latch engages around the usually bow-shaped locking bolt - also called lock holder - around - which is usually attached to the body in the case of a motor vehicle. Reached the catch by pivoting, starting from an open position, a closed position, the catch is finally locked by means of the pawl. Then the catch can not be rotated back in the direction of the open position and the locking bolt will not leave the locking mechanism. For opening it is necessary to move the pawl out of the detent position.

Ein solches Schloss ist regelmäßig über einen Mechanismus mit einem Schließzylinder nebst Griff verbunden. Durch Betätigen des Griffs kann ein verrastetes Gesperre entrastet werden, um eine zugehörige Tür oder Klappe öffnen zu können. Mithilfe des Schließzylinders kann durch ein Verriegelungsmodul eine Tür oder Klappe so abgeschlossen werden, dass diese nicht mehr durch Betätigen des Griffs geöffnet werden kann. Modul im Sinne der Erfindung bedeutet, dass die Aufnahme zumindest der Schaltnuss in einem ein- oder mehrteiligen separaten Gehäuse aufgenommen ist. Separates Gehäuse wiederum bedeutet, dass das Türschloss an das Modul montierbar ist, zumindest ein weiteres Gehäuseteil aufweist. Eine abgeschlossene Tür oder Klappe muss erst wieder aufgeschlossen werden, um die Tür oder Klappe im Anschluss daran wieder öffnen zu können. Das Verriegelungsmodul dient der Übertragung einer Drehbewegung eines Schlüssels auf einen Mechanismus, der im verschlossenen Zustand verhindert, dass das Gesperre durch Betätigen des Griffs entrastet und die Tür oder Klappe anschließend geöffnet werden kann.Such a lock is regularly connected via a mechanism with a lock cylinder and handle. By pressing the handle, a latched catch can be unlatched to open an associated door or flap. Using the lock cylinder, a door or flap can be locked by a locking module so that it can not be opened by pressing the handle. Module in the sense of the invention means that the inclusion of at least the sliding nut is accommodated in a single or multi-part separate housing. Separate housing in turn means that the door lock can be mounted on the module, at least one further housing part. A closed door or flap must first be unlocked to reopen the door or flap afterwards. The locking module is used to transmit a rotary movement of a key to a mechanism that prevents in the closed state, the locking mechanism by pressing the handle unlocked and the door or flap can then be opened.

Die Druckschrift DE 101 52 618 A1 offenbart ein Schloss für ein Kraftfahrzeug mit Schließzylinder und Griff. Ein in einem Außengriff befindlicher Schließzylinder ist über eine Stange mit einem Schlüsselrotor verbunden. Eine Drehbewegung eines Schlüssels wird durch den Schließzylinder auf den Schlüsselrotor übertragen. Eine entsprechende Drehbewegung des Schlüsselrotors überträgt sich auf einen Hebelmechanismus, der durch Drehen das Aufschließen oder Abschließen einer Fahrzeugtür bewirkt. Mithilfe einer Stange kann eine Betätigung des Außengriffs auf das Gesperre für ein Entriegeln übertragen werden.The publication DE 101 52 618 A1 discloses a lock for a motor vehicle with lock cylinder and handle. A locking cylinder located in an outer handle is connected via a rod to a key rotor. A rotary movement of a key is transmitted through the lock cylinder to the key rotor. A corresponding rotational movement of the key rotor is transmitted to a lever mechanism which causes the unlocking or locking of a vehicle door by turning. Using a rod, an operation of the outer handle can be transferred to the locking mechanism for unlocking.

Aus der Druckschrift US 2011/0179835 A1 geht eine Tür mit Schloss für ein Kraftfahrzeug hervor, welche mit einem gattungsgemäßen Verriegelungsmodul ausgerüstet ist. Die Tür kann durch einen Schlüssel nebst Schließzylinder abgeschlossen oder aufgeschlossen werden. Eine Drehbewegung des Schlüssels in dem Schließzylinder wird durch einen Übertragungsmechanismus auf einen Schließmechanismus übertragen, um so die Tür des Kraftfahrzeuges aufschließen bzw. abschließen zu können.From the publication US 2011/0179835 A1 goes out a door with lock for a motor vehicle, which is equipped with a generic locking module. The door can be locked or unlocked by a key and lock cylinder. A rotational movement of the key in the lock cylinder is transmitted by a transmission mechanism to a locking mechanism, so as to unlock or close the door of the motor vehicle.

Der Erfindung liegt das technische Problem zu Grunde, ein derartiges Verriegelungsmodul so weiter zu entwickeln, dass eine einfache Fertigung mit einer hohen Funktionssicherheit und zugleich kleinem Bauraum zur Verfügung gestellt wird. Außerdem soll eine flexible Anpassung an unterschiedliche geometrische Erfordernisse in z. B. einer Kraftfahrzeugtür ermöglicht werden.The invention is based on the technical problem to further develop such a locking module that a simple production with a high reliability and at the same time small space available. In addition, a flexible adaptation to different geometric requirements in z. B. a motor vehicle door.

Diese Aufgabe wird im Rahmen der Erfindung bei einem gattungsgemäßen Verriegelungsmodul dadurch gelöst, dass ein Leergang zwischen dem Übertragungshebel und der Schaltnuss vorhanden ist, der eine Bewegung der Schaltnuss verzögert auf den Mitnehmer zu übertragen vermag, wobei die Drehachse der Schaltnuss und die Drehachse des Übertragungshebels einen Winkel kleiner als 180° einschließen. - Nach vorteilhafter Ausgestaltung weist der Übertragungshebel für ein Sichern gegen ein Verschieben eine ringförmig umlaufende Nut auf der Außenseite seiner Mantelfläche auf, in die ein geeignet vorstehender Bereich des Gehäuses hineinreicht.This object is achieved in the context of the invention in a generic locking module characterized in that a backlash between the transmission lever and the shift nut is present, which is able to delay a movement of the shift nut transmitted to the driver, wherein the axis of rotation of the Schaltnuss and the axis of rotation of the transmission lever a Include angles smaller than 180 °. - According to an advantageous embodiment, the transmission lever for securing against displacement on an annular circumferential groove on the outside of its lateral surface, in which extends a suitably projecting portion of the housing.

Die Mechanik umfasst den Mitnehmer, der durch eine Drehbewegung der Schaltnuss linear bewegt wird. Wird die Schaltnuss also im eingebauten Zustand des Verriegelungsmoduls durch Drehen eines mit der Schaltnuss verbundenen Schließzylinders durch einen Schlüssel gedreht, so wird diese Drehbewegung durch die Mechanik in eine lineare Bewegung des Mitnehmers umgewandelt. Die lineare Bewegung betätigt wiederum im eingebauten Zustand des Verriegelungsmoduls eine Mechanik, die das Entriegeln bzw. Aufschließen oder Verriegeln bzw. Zuschließen des Schlosses bewirkt.The mechanism comprises the driver, which is moved linearly by a rotational movement of the shift nut. If, in the installed state of the locking module, the sliding nut is thus turned by a key by turning a locking cylinder connected to the sliding nut, this rotational movement is converted by the mechanism into a linear movement of the driver transformed. The linear movement in turn actuates a mechanism in the installed state of the locking module, which causes the unlocking or unlocking or locking or locking the lock.

Die Schaltnuss ist durch das Gehäuse drehbar gelagert. Durch das Gehäuse wird also ein Lager bereitgestellt, welches die Schaltnuss aufnimmt und die drehbare Lagerung der Schaltnuss bewirkt. Hierdurch wird die Zahl der Teile gering gehalten, um ein Verriegelungsmodul bereitzustellen. Dies hält den technischen Fertigungsaufwand gering und bewirkt gleichzeitig den Vorteil einer hohen Funktionssicherheit. Die Funktionssicherheit wird insbesondere dadurch gewährleistet, dass die Schaltnuss umfänglich im Gehäuse aufgenommen ist.The shift nut is rotatably supported by the housing. Thus, a bearing is provided by the housing, which receives the Schaltnuss and causes the rotatable mounting of the shift nut. As a result, the number of parts is kept small to provide a locking module. This keeps the technical production effort low and at the same time brings the advantage of a high reliability. The reliability is ensured in particular by the fact that the Schaltnuss is received circumferentially in the housing.

Erfindungsgemäß umfasst die Mechanik den Übertragungshebel, der eine Bewegung der Schaltnuss auf den Mitnehmer überträgt. Dabei ist der Übertragungshebel so beschaffen, dass eine Drehbewegung der Schaltnuss ein Drehen des Übertragungshebels bewirkt. Der Übertragungshebel ist darüber hinaus mit dem Mitnehmer so verbunden, dass ein Drehen des Übertragungshebels eine lineare Bewegung des Mitnehmers bewirkt. Der Übertragungshebel ermöglicht es vorteilhaft, Zusatzfunktionen und/oder besonderer Ausgestaltungen vorzusehen.According to the invention, the mechanism comprises the transmission lever which transmits a movement of the shift nut to the driver. In this case, the transmission lever is such that a rotational movement of the Schaltnuss causes a rotation of the transmission lever. The transmission lever is also connected to the driver so that a rotation of the transmission lever causes a linear movement of the driver. The transmission lever advantageously makes it possible to provide additional functions and / or special configurations.

Erfindungsgemäß gibt es einen Leergang zwischen der Schaltnuss und dem Mitnehmer bzw. dem Übertragungshebel und der Schaltnuss. Durch den Leergang wird bewirkt, dass ein Drehen der Schaltnuss nicht zwingend sofort den Mitnehmer linear bewegt. Ein versehentliches Drehen eines Schlüssels bewirkt daher nicht unmittelbar ein Verriegeln oder Entriegeln des Schlosses. Erst nach Durchlaufen des Leergangs bewirkt ein weiteres Drehen eines Schlüssels eine lineare Bewegung des Mitnehmers und somit ein Verriegeln oder Entriegeln eines zugehörigen Schlosses.According to the invention there is a backlash between the Schaltnuss and the driver or the transmission lever and the Schaltnuss. Due to the backlash, it is ensured that a rotation of the shift nut does not necessarily move the driver linearly immediately. Therefore, accidentally turning a key does not immediately lock or unlock the lock. Only after passing through the backlash causes a further rotation of a key a linear movement of the driver and thus locking or unlocking an associated lock.

Ein geeignet großer Leergang bei einer Drehbewegung der Schaltnuss von nahezu bis zu 120° kann besonders einfach zwischen der Schaltnuss und dem Übertragungshebel realisiert werden. Vorteilhaft reicht in einer Ausführungsform eine insbesondere zylinderförmige oder kegelförmige Mantelfläche der Schaltnuss in eine insbesondere zylinder- oder kegelförmige Mantelfläche zumindest teilweise hinein. Am Außenumfang der Mantelfläche der Schaltnuss befindet sich dann ein Anschlag, der durch Drehen der Schaltnuss gegen einen Anschlag bewegt werden kann, der sich am Innenumfang der Mantelfläche des Übertragungshebels befindet. Ist der Anschlag der Schaltnuss durch Drehen der Schaltnuss gegen den Anschlag des Übertragungshebels bewegt worden, so bewirkt ein darüber hinaus gehendes Drehen der Schaltnuss eine Drehbewegung des Übertragungshebels. Solange der Anschlag der Schaltnuss durch Drehen der Schaltnuss nicht gegen den Anschlag des Übertragungshebels bewegt worden ist, dreht sich der Übertragungshebel nicht zusammen mit der Schaltnuss. Es ist so also ein Leergang zwischen Schaltnuss und Übertragungshebel bereitgestellt.A suitable large backlash with a rotational movement of the Schaltnuss of almost up to 120 ° can be particularly easily realized between the Schaltnuss and the transmission lever. Advantageously, in one embodiment, an in particular cylindrical or conical lateral surface of the sliding nut extends at least partially into a cylindrical or conical circumferential surface in particular. On the outer circumference of the lateral surface of the shift nut is then a stop which can be moved by turning the switch nut against a stop which is located on the inner circumference of the lateral surface of the transmission lever. If the stopper of the sliding nut has been moved by turning the sliding nut against the stop of the transmission lever, an additional turning of the operating handle causes a rotational movement of the transmission lever. As long as the stop of the shift nut has not been moved against the stop of the transmission lever by turning the control nut, the transmission lever does not rotate together with the control nut. It is thus provided a backlash between the shift nut and transmission lever.

In analoger Weise kann dieser Leergang realisiert werden, indem die Mantelfläche des Übertragungshebels in die Mantelfläche der Schaltnuss zumindest teilweise hinein reicht. Dann befindet sich ein Anschlag auf der Außenseite der Mantelfläche des Übertragungshebels sowie ein Anschlag auf der Innenseite der Mantelfläche der Schaltnuss.In an analogous manner, this backlash can be realized by the lateral surface of the transmission lever in the lateral surface of the Schaltnuss extends at least partially. Then there is a stop on the outside of the lateral surface of the transmission lever and a stop on the inside of the lateral surface of the sliding nut.

Es ist auch möglich, derartige Anschläge beispielsweise an Stirnflächen von Schaltnuss und Übertragungshebel vorzusehen, um einen großen Leergang realisieren zu können. Es ist allerdings zu bevorzugen, dass die Schaltnuss in den Übertragungshebel wie beschrieben hineinreicht oder umgekehrt, um eine große Robustheit zu erzielen.It is also possible to provide such stops, for example, on end faces of the shift nut and transmission lever in order to realize a large amount of backlash. However, it is preferable that the shift nut extends into the transfer lever as described, or vice versa, to achieve great ruggedness.

Ein solcher Leergang beträgt in einer Ausführungsform zumindest 20°, vorzugsweise wenigstens 25°. Es ist bei dieser Ausführungsform erforderlich, die Schaltnuss um wenigstens 20°, vorzugsweise um wenigstens 25° zu drehen, ehe ein Übertragungshebel mit gedreht wird. Es wird so besonders zuverlässig vermieden, dass ein versehentliches Drehen eines Schlüssels ein Schloss unbeabsichtigt verriegelt oder entriegelt. Ein Leergang wird hierbei dadurch definiert, dass der Schließzylinder oder Schlüssel um eine Einsteckstellung, das heißt einer Nullposition, in positive und negative Richtung drehbar ist, ohne eine Bewegung, insbesondere eine Moment, von der Schaltnuss auf den Übertragungshebel und/oder den Mitnehmer zu bewirken.Such a backlash is in one embodiment at least 20 °, preferably at least 25 °. It is necessary in this embodiment, the Schaltnuss by at least 20 °, preferably at least 25 ° to rotate before a transmission lever is rotated with. It is thus particularly reliably avoided that accidentally turning a key inadvertently locks or unlocks a lock. A backlash is in this case defined by the fact that the lock cylinder or key to a insertion position, that is, a zero position, is rotatable in positive and negative directions, without a movement, in particular a moment to effect from the shift nut on the transmission lever and / or the driver ,

Erfindungsgemäß sind die Drehachsen von Schaltnuss und Übertragungshebel in einem Winkel zueinander angeordnet, der kleiner als 180° ist. Diese Anordnung des Übertragungshebels relativ zur Schaltnuss dient dazu, eine Drehbewegung der Schaltnuss in eine lineare Bewegung des Mitnehmers in einer gewünschten Richtung umzuwandeln, da die Auswahl des Winkels sich auf die Bewegungsrichtung des Mitnehmers auswirkt. Das Modul kann bei dieser Ausführungsform besonders leicht an verschiedene Einbausituationen angepasst werden.According to the invention, the axes of rotation of the sliding nut and the transmission lever are arranged at an angle to one another which is smaller than 180 °. This arrangement of the transmission lever relative to the shift nut serves to convert a rotational movement of the shift nut in a linear movement of the driver in a desired direction, since the selection of the angle affects the direction of movement of the driver. The module can be adapted particularly easily to different installation situations in this embodiment.

In einer Ausführungsform ist der Übertragungshebel durch das Gehäuse drehbar gelagert, um so die Zahl der Teile und damit den Fertigungsaufwand gering zu halten.In one embodiment, the transmission lever is rotatably supported by the housing so as to keep the number of parts and thus the manufacturing cost low.

In einer Ausführungsform ist der Mitnehmer durch das Gehäuse verschiebbar gelagert, um so die Zahl der Teile und damit den Fertigungsaufwand gering zu halten.In one embodiment, the driver is slidably supported by the housing so as to keep the number of parts and thus the manufacturing cost low.

In einer Ausführungsform ist eine Feder vorhanden, die im Anschluss an eine Drehbewegung der Schaltnuss ein durch die Schaltnuss bewegbares Bauteil des Verriegelungsmoduls in eine Zwischenstellung zurückbewegt und zwar insbesondere den Übertragungshebel. Es kann so eine neutrale Stellung für den Übertragungshebels vorgesehen werden, sobald keine oder zumindest keine übermäßig hohe Kraft auf den Übertragungshebel wirkt. Hierdurch kann zuverlässig sichergestellt werden, dass ein Leergang zwischen Schaltnuss und Übertragungshebel auch dann verbleibt, wenn die Schaltnuss im Anschluss an ein Entriegeln oder Verriegeln durch einen Schlüssel zurückgedreht wird, um den Schlüssel vom Schließzylinder, in der Einsteckstellung bzw. Nullposition des Schließzylinders, abnehmen zu können.In one embodiment, a spring is provided which, following a rotational movement of the shift nut, moves a component of the locking module which is movable by the sliding nut back into an intermediate position, in particular the transmission lever. It can be provided as a neutral position for the transmission lever as soon as no or at least no excessively high force acts on the transmission lever. In this way, it can be reliably ensured that an idle movement between the shift nut and the transmission lever also remains if the shift nut is turned back by a key following unlocking or locking in order to remove the key from the lock cylinder, in the insertion position or zero position of the lock cylinder can.

Nachfolgend wird die Erfindung anhand von Figuren näher erläutert.The invention will be explained in more detail with reference to figures.

Die Figur 1 zeigt ein Modul für ein Verriegeln eines Schlosses, bei dem eine Hälfte eines Gehäuses 1 abgenommen ist, um den Blick in das Innere des Moduls freizugeben. Die Figur 2 zeigt einen Ausschnitt der Figur 1, jedoch ohne Schaltnuss 2. Durch das Gehäuse 1, von denen in den beiden Figuren nur eine von zwei Gehäuseschalen dargestellt ist, wird eine Schaltnuss 2 drehbar gelagert. Die Mantelfläche der Schaltnuss 2 weist einen nach außen ringartig vorstehenden Bereich 3 auf, der in eine ringartig verlaufende Nut 4 des Gehäuses 1 hinein reicht. Nut 4 und vorstehender Bereich 3 tragen dazu bei, dass die Schaltnuss 2 einerseits drehbar durch das Gehäuse 1 gelagert und andererseits gegen ein Verschieben gesichert ist. Eine derartige gestaltete Aufnahme der Schaltnuss dient der Funktionssicherheit. Alternativ kann die Schaltnuss 2 mit einer ringförmigen Nut an ihrer Außenfläche versehen sein, in die ein vorstehender Ring des Gehäuses 1 hineinreicht, um die Schaltnuss einerseits drehbar zu lagern und andererseits gegen ein Verschieben zu sichern. Um die drehbare Lagerung zu stabilisieren, weist die Schaltnuss 2 in einer Ausführungsform der Erfindung zumindest einen ringförmigen oder anders rotationssymmetrischen Bereich 5 der Mantelfläche der Schaltnuss 2 auf, der in einer Ausführungsform an den vorstehenden Bereich 3 angrenzt und der beispielsweise durch zwei Innenseiten 6 des Gehäuses 1 drehbar gehalten ist.The FIG. 1 shows a module for locking a lock, in which one half of a housing 1 is removed to release the view into the interior of the module. The FIG. 2 shows a part of the FIG. 1 , but without a sliding nut 2. By the housing 1, of which only one of two housing shells is shown in the two figures, a shift nut 2 is rotatably mounted. The lateral surface of the sliding nut 2 has an outwardly ring-like projecting portion 3, which extends into an annular groove 4 of the housing 1 into it. Groove 4 and projecting area 3 contribute to the fact that the sliding nut 2 on the one hand rotatably supported by the housing 1 and on the other hand is secured against displacement. Such a designed reception of the shift nut serves the functional safety. Alternatively, the Schaltnuss 2 may be provided with an annular groove on its outer surface into which a protruding ring of the housing 1 extends, on the one hand rotatably support the Schaltnuss and on the other hand to secure against displacement. In order to stabilize the rotatable mounting, the shift nut 2 in an embodiment of the invention, at least one annular or other rotationally symmetrical region 5 of the lateral surface of the sliding nut 2, which in one embodiment adjacent to the projecting portion 3 and which is rotatably supported, for example, by two inner sides 6 of the housing 1.

Dieser drehbar gelagerte Endbereich der Schaltnuss 2 kann durch eine angrenzende Öffnung im Gehäuse 1 hindurch beispielsweise mit einer nicht dargestellten Stange verbunden werden oder sein, die wiederum mit einem Schließzylinder einer Tür oder Klappe verbunden ist. Die Verbindung der Stange mit der Schaltnuss 2 kann durch Formschluss, Kraftschluss und/oder Stoffschluss bereitgestellt sein. Ein Drehen des Schließzylinders mithilfe eines Schlüssels überträgt sich aufgrund der Stange oder eines gleich wirkenden Bauteils auf die Schaltnuss 2, die für ein Verriegeln oder Entriegeln eines zugehörigen Schlosses entsprechend mit gedreht wird.This rotatably mounted end portion of the sliding nut 2 can be connected by an adjacent opening in the housing 1, for example, with a rod, not shown, or be, which in turn is connected to a lock cylinder of a door or flap. The connection of the rod with the Schaltnuss 2 can be provided by positive engagement, adhesion and / or material bond. A turning of the lock cylinder by means of a key is due to the rod or an equivalent component on the sliding nut 2, which is rotated for locking or unlocking a corresponding lock accordingly.

Die Mantelfläche der Schaltnuss 2 verjüngt sich in einer Ausgestaltung Konus artig zu einem Ende hin, an welches ein Übertragungshebel 7 angrenzt. Diese Verjüngung erfolgt vorzugsweise ausgehend von dem mit einer Stange verbindbaren Endbereich, insbesondere ausgehend vom vorstehenden Bereich 3 in Richtung des Übertragungshebels 7. Ein Endbereich dieser Verjüngung reicht in eine Öffnung 8 des Übertragungshebels 7 hinein.The lateral surface of the sliding nut 2 tapers conically in one embodiment towards an end, to which a transmission lever 7 is adjacent. This taper preferably takes place starting from the end region that can be connected to a rod, in particular starting from the protruding region 3 in the direction of the transmission lever 7. An end region of this taper extends into an opening 8 of the transmission lever 7.

Der Übertragungshebel 7 ist wiederum drehbar durch das Gehäuse 1 gelagert bzw. gehalten. Darüber hinaus ist der Übertragungshebel 7 durch das Gehäuse 1 gegen ein Verschieben entlang seiner Drehachse gesichert. Beispielsweise weist der Übertragungshebel 7 für ein Sichern gegen ein Verschieben eine ringförmig umlaufende Nut 9 auf der Außenseite seiner Mantelfläche auf, in die ein geeignet vorstehender Bereich 10 des Gehäuses 1 hineinreicht. An die Nut 9 angrenzende Bereiche sind vorteilhaft rotationssymmetrisch und werden durch entsprechende Gehäuseflächen drehbar gehalten bzw. gelagert, um die Lagerung zu stabilisieren. Da die Schaltnuss 2 mit einem sich verjüngenden Ende in den Übertragungshebel 7 hineinreicht, ist es möglich, die Drehachse der Schaltnuss 2 in einem Winkel ungleich 180° relativ zur Drehachse des Übertragungshebels 7 anzuordnen. Das heißt, die Schaltnuss 2 und der Übertragungshebel 7 können auch nicht parallel zueinander ausgerichtet sein. Hierdurch wird es möglich, das Modul durch Auswahl eines geeigneten Winkels zwischen den beiden Drehachse flexibel an geometrische Erfordernisse, in zum Beispiel einer Kraftfahrzeugtür, anzupassen.The transmission lever 7 is in turn rotatably supported or held by the housing 1. In addition, the transmission lever 7 is secured by the housing 1 against displacement along its axis of rotation. For example, the transmission lever 7 for securing against displacement on an annular circumferential groove 9 on the outside of its lateral surface into which a suitably projecting portion 10 of the housing 1 extends. Adjacent to the groove 9 areas are advantageous rotationally symmetric and are rotatably supported by respective housing surfaces or stored to stabilize the storage. Since the Schaltnuss 2 extends with a tapered end in the transmission lever 7, it is possible to arrange the axis of rotation of the Schaltnuss 2 at an angle not equal to 180 ° relative to the axis of rotation of the transmission lever 7. That is, the Schaltnuss 2 and the transmission lever 7 can not be aligned parallel to each other. This makes it possible to flexibly adapt the module by selecting a suitable angle between the two axis of rotation to geometric requirements, in for example a motor vehicle door.

Der Übertragungshebel 7 verfügt über einen Hebelarm 11, der beweglich mit einem Mitnehmer 12 verbunden ist und zwar vorzugsweise mit einem Endbereich. Der Mitnehmer 12 wird durch das Gehäuse 1 vorzugsweise verschiebbar gelagert. Die Verbindung zwischen dem Hebel 11 und dem Mitnehmer 12 ist derart, dass ein Verschwenken des Hebels 11 ein Verschieben des Mitnehmers 12 bewirkt. Der Mitnehmer 12 kann zu diesem Zweck L-förmig sein. Vorzugsweise das kurze Ende ist dann mit dem freien Ende des Hebels 11 für ein Verschieben des Mitnehmers 12 Verschwenken des Übertragungshebels 7 verbunden. Die Verbindung zwischen dem Hebel 11 und dem Mitnehmer 12 umfasst bevorzugt ein Spiel, um den Mitnehmer 12 besonders zuverlässig und einfach durch ein Verschwenken des Hebels 11 verschieben zu können, der durch ein hinreichendes Drehen der Schaltnuss 2 verschwenkt wirdThe transmission lever 7 has a lever arm 11 which is movably connected to a driver 12, preferably with an end portion. The driver 12 is preferably mounted displaceably by the housing 1. The connection between the lever 11 and the driver 12 is such that a pivoting of the lever 11 causes a displacement of the driver 12. The driver 12 may be L-shaped for this purpose. Preferably, the short end is then connected to the free end of the lever 11 for displacing the driver 12 pivoting the transmission lever 7. The connection between the lever 11 and the driver 12 preferably includes a game to move the driver 12 particularly reliable and easy by pivoting the lever 11, which is pivoted by a sufficient rotation of the sliding nut 2

Der Übertragungshebel 7 verfügt über zwei Anschläge 13 und 14 am Innenumfang seiner Öffnung 8. Ein Anschlag am Außenumfang der Schaltnuss 2 kann zwischen diesen beiden Anschlägen 13 und 14 hin und her bewegt werden. Auf diese Weise wird ein Leergang zwischen Schaltnuss 2 und Übertragungshebel 7 bereitgestellt. Bevorzugt ist der Abstand zwischen den beiden Anschlägen 13 und 14 so gewählt, dass der Anschlag der Schaltnuss 2 von einer mittleren Stellung aus um bis zu + 25° oder -25° verdreht werden kann, ohne dass der Übertragungshebel mitgedreht wird. Erst bei Drehungen größer als 25° erreicht dann der Anschlag der Schaltnuss 2 einen entsprechenden Anschlag 13 oder 14 des Übertragungshebels 7, so dass im Anschluss daran der Übertragungshebel 7 wird.The transfer lever 7 has two stops 13 and 14 on the inner periphery of its opening 8. A stop on the outer periphery of the shift nut 2 can be moved between these two stops 13 and 14 back and forth. In this way, a backlash between the shift 2 and transmission lever 7 is provided. Preferably, the distance between the both stops 13 and 14 are chosen so that the stop of the sliding nut 2 can be rotated from a central position by up to + 25 ° or -25 °, without the transmission lever is rotated. Only at rotations greater than 25 ° then reaches the stop of the sliding nut 2 a corresponding stop 13 or 14 of the transmission lever 7, so that subsequently the transmission lever 7 is.

In den Figuren 1 und 2 wird nur eine Schale des Gehäuses 1 gezeigt. Das Gehäuse 1 umfasst eine weitere Schale, die mit der in den Figuren 1 und 2 gezeigten Gehäuseschale so verbunden werden kann, dass sich Schaltnuss 2, Übertragungshebel 7 vollständig oder zumindest nahezu vollständig im Gehäuse 1 befinden. Der Mitnehmer 12 befindet sich grundsätzlich nur teilweise im Gehäuse 1. Sein aus dem Gehäuse 1 herausreichendes Ende ist mit einer nicht dargestellten Mechanik verbunden, mit der das zugehörige ebenfalls nicht dargestellte Schloss verriegelt oder entriegelt werden kann.In the Figures 1 and 2 only one shell of the housing 1 is shown. The housing 1 comprises a further shell, with the in the Figures 1 and 2 shown housing shell can be connected so that the shift nut 2, transmission lever 7 are completely or at least almost completely in the housing 1. The driver 12 is basically only partially in the housing 1. Its reaching out of the housing 1 end is connected to a mechanism, not shown, with which the associated lock, also not shown, can be locked or unlocked.

Innerhalb des Gehäuses kann eine Aufnahmeeinheit 15 vorgesehen sein, die ein oder mehrere Bereiche für eine Aufnahme von elektrischen Komponenten bereitstellt und/oder die mit ein oder mehreren elektrischen Leiterbahnen versehen ist. Die Aufnahmeeinheit 15 wird vorzugsweise formschlüssig gehalten bzw. befestigt, um die Zahl der Teile zu minimieren und den Fertigungsaufwand gering zu halten.Within the housing, a receiving unit 15 may be provided, which provides one or more areas for receiving electrical components and / or which is provided with one or more electrical conductor tracks. The receiving unit 15 is preferably held and secured in a form-fitting manner in order to minimize the number of parts and to keep the production costs low.

Das aus dem Gehäuse 1 heraus reichende Ende des Mitnehmers 12 kann wie in der Figur 3 gezeigt ein Langloch 16 aufweisen, das dazu dient, dass eine Innenbetätigung eines Schlosses vom Innenraum eines Kraftfahrzeug aus unabhängig von seiner Außenbetätigung fungieren kann. Das Langloch könnte auch entfallen, dann würde aber bei einem Öffnen der Tür mittels der Innenbetätigung der Mitnehmer und der Übertragungshebel mit bewegt werden, was wiederum in einem schwereren Betätigen resultieren würde. Es müsste mehr Reibung überwunden und es müssten auch mehr Bauteile bewegt werden. In der Figur 3 wird weiter eine zweite, in diesem Ausführungsbeispiel unabhängige Gehäuseschale des Gehäuses 1 gezeigt.The reaching out of the housing 1 out end of the driver 12 can, as in the FIG. 3 shown having a slot 16 which serves that an internal operation of a lock from the interior of a motor vehicle can act independently of its external operation. The slot could also be omitted, but then would be moved at an opening of the door by means of the internal operation of the driver and the transmission lever, which in turn would result in a heavier actuation. It would have overcome more friction and it would have to be moved more components. In the FIG. 3 Furthermore, a second, in this embodiment, independent housing shell of the housing 1 is shown.

Wie in den Figuren 4 und 5 dargestellt, kann das Modul eine Schenkelfeder 17 umfassen, die dafür Sorge trägt, dass der Übertragungshebel 7 im Anschluss an ein Verschwenken wieder in eine mittlere Position zurück bewegt wird. Die Schenkelfeder 17 kann durch eine Welle 20 des Übertragungshebels 7 gehalten sein. Die beiden Schenkel 18 und 19 der Schenkelfeder 17 liegen einerseits an dem Gehäuse 1 derart einseitig an, dass diese durch ein entsprechendes Verschwenken des Übertragungshebels 7 mittels eines teil kreisförmigen vorstehenden Elements 21 des Übertragungshebels 7 ausgelenkt werden können und zwar insbesondere gegen eine Vorspannung der Feder 17. Sobald auf den Übertragungshebel 7 keine oder keine hinreichend hohe Kraft für ein Verschwenken mehr ausgeübt wird, trägt die Feder 17 dafür Sorge, dass der Übertragungshebel 7 in die in der Figur 5 gezeigte Position, das heißt Einsteckstellung bzw. Nullposition, zurückgedreht wird.As in the FIGS. 4 and 5 As shown, the module may comprise a leg spring 17, which ensures that the transmission lever 7 is moved back to a middle position after pivoting. The leg spring 17 may be held by a shaft 20 of the transmission lever 7. The two legs 18 and 19 of the leg spring 17 are on the one hand on the housing 1 on one side so that they can be deflected by a corresponding pivoting of the transmission lever 7 by means of a partially circular projecting element 21 of the transmission lever 7 and in particular against a bias of the spring 17th As soon as no or no sufficiently high force for pivoting is exerted on the transmission lever 7, the spring 17 ensures that the transmission lever 7 in the in the FIG. 5 shown position, that is insertion or zero position, is turned back.
