This engagement surface is in contact with the connecting means, so that upon axial displacement of the

Description
Kupplungssystem für ein elektromechanisches Schloss Coupling system for an electromechanical lock
Die Erfindung betrifft ein Kupplungssystem für ein elektromechanisches Schloss sowie ein elektromechanisches Schloss mit einem derartigen Kupplungssystem. The invention relates to a coupling system for an electromechanical lock and an electromechanical lock with such a coupling system.
Aus dem Stand der Technik sind Kupplungssysteme für elektromechanische Schlösser bekannt. Derartige Kupplungssysteme werden meist auf elektronischem Weg angesteuert und betätigen eine elektromechanische Kupplungsvorrichtung, um ein Schloss freizugeben oder zu blockieren. Zu diesem Zweck empfängt eine Coupling systems for electromechanical locks are known from the prior art. Such coupling systems are usually controlled electronically and operate an electromechanical coupling device to release a lock or block. For this purpose receives one

Kupplungsmittel angesteuert, um das Schloss freizugeben oder zu blockieren. Coupling means controlled to release the lock or block.
Bekannt sind insbesondere Systeme, bei denen die Steuerelektronik in einem In particular, systems are known in which the control electronics in a
Handknauf angeordnet ist, und das Kupplungssystem zwischen einem Blockierzustand und einem Freigabezustand umschaltbar ist. Im Blockierzustand lässt sich der Hand knob is arranged, and the coupling system between a blocking state and a release state is switchable. In the blocking state can be the
Handknauf nicht drehen. Im Freigabezustand lässt sich der Handknauf drehen und betätigt ein Sperrmittel, beispielsweise die Falle oder die Sperrnase eines Schlosses. Dabei ist insbesondere vorgesehen, dass der Freigabezustand nur für eine kurze Zeit, meist nur wenige Sekunden, aktivierbar ist, und das Kupplungssystem danach wieder den Blockierzustand einnimmt. Derartige bekannte Kupplungssysteme umfassen ein Gehäuse und einen im Gehäuse drehbar gelagerten Kern sowie ein Verbindungsmittel, welches eine mechanische formschlüssige und drehfeste Verbindung des Kerns mit dem Gehäuse herstellt. Do not turn hand knob. In the release state, the hand knob can rotate and actuates a blocking means, such as the case or the locking lug of a lock. It is provided in particular that the release state only for a short time, usually only a few seconds, can be activated, and the clutch system then assumes the blocking state again. Such known coupling systems comprise a housing and a housing rotatably mounted in the core and a connecting means which produces a mechanical positive and non-rotatable connection of the core to the housing.
Die bekannten Kupplungssysteme sind jedoch übermäßig kompliziert in ihrem Aufbau und auch nicht geeignet, an unterschiedliche Anwendungen angepasst zu werden. So wäre es wünschenswert, ein und dasselbe elektromechanische Kupplungssystem sowohl für Hybridzylinder, die auf einer Seite elektronisch und auf der anderen Seite mechanisch betätigt werden, als auch für beidseitig elektronisch betätigte Zylinder zu verwenden. Eine Verwendung der Komponenten desselben Kupplungssystems für die bei Briefkästen oder Garderobenschränken verbreiteten Hebelzylinder, bei denen der Zylinderkern direkt mit einem Schließhebel verbunden ist und nicht in eine Sperrnase eingreift, und bei denen eine Betätigung nur von einer Seite erfolgt, wäre ebenfalls vorteilhaft. However, the known coupling systems are overly complicated in structure and also not suitable to be adapted to different applications. Thus, it would be desirable to use one and the same electromechanical coupling system both for hybrid cylinders that are electronically actuated on one side and mechanically actuated on the other side, as well as for double-sided electronically actuated cylinders. A use of the components of the same coupling system for the distributed in mailboxes or lockers lever cylinder, in which the cylinder core is directly connected to a closing lever and does not engage in a locking lug, and in which an actuation takes place only from one side, would also be advantageous.
Diese und andere Aufgaben werden erfindungsgemäß durch ein Kupplungssystem gemäß Anspruch 1 gelöst. These and other objects are achieved by a coupling system according to claim 1.
Erfindungsgemäß ist ein separates Kupplungselement vorgesehen, das im According to the invention, a separate coupling element is provided, which in the
Wesentlichen entlang einer Längsachse des Kerns von einem Freigabezustand in einen Blockierzustand verschiebbar ist.

In the blocking state, the connecting means engages both in the core, as well as in the housing in a form-fitting manner, so that the core and housing are mechanically connected. Rotation of the core in the locked state is thus prevented.
Um das Verbindungsmittel im Blockierzustand ins Gehäuse zu verschieben, weist das Kupplungselement an seinem äußeren Umfang eine sich gegenüber der Längsachse im Wesentlichen konisch erweiternde Eingriffsfläche auf. Diese Eingriffsfläche steht in Kontakt mit dem Verbindungsmittel, sodass bei einer axialen Verschiebung des In order to move the connecting means in the blocking state into the housing, the coupling element has on its outer circumference a relative to the longitudinal axis substantially conically widening engagement surface. This engagement surface is in contact with the connecting means, so that upon axial displacement of the

Es muss somit lediglich das Kupplungselement entlang der Längsachse des Kerns verschoben werden, um das Kupplungssystem vom Blockierzustand in den Clutch element, the connecting means is pressed from the core into the housing. Thus, only the coupling element has to be displaced along the longitudinal axis of the core in order to move the coupling system from the blocking state into the

Der Blockierzustand stellt dabei in der Regel den Ausgangszustand dar, sodass zum Erreichen des Freigabezustands das Kupplungselement verschoben werden muss.

The blocking state is usually the initial state, so that the coupling element must be moved to reach the release state. For substantially axial displacement of the coupling element along the longitudinal axis of the core can be provided according to the invention that the
Kupplungselement über ein Federelement, vorzugsweise über eine Spiralfeder, mit einer Motorspindel eines Motors verbunden ist. Insbesondere kann vorgesehen sein, dass das Kupplungselement zur im Wesentlichen axialen Verschiebung entlang der Längsachse des Kerns über ein Federelement, vorzugsweise über eine Spiralfeder, mit einer, an einer Motorspindel eines Motors drehfest angeordneten Motormutter verbunden ist. Natürlich sind erfindungsgemäß auch andere Umsetzmechanismen vorgesehen, um eine federnde Verschiebung des Kupplungselements im Wesentlichen entlang der Längsachse des Kerns zu erzielen. Coupling element via a spring element, preferably via a coil spring, is connected to a motor spindle of a motor. In particular, it may be provided that the coupling element for substantially axial displacement along the longitudinal axis of the core via a spring element, preferably via a coil spring, with a motor rotatably mounted on a motor spindle of a motor motor nut is connected. Of course, other Umsetzmechanismen are provided according to the invention to achieve a resilient displacement of the coupling element substantially along the longitudinal axis of the core.
Ausgehend vom Blockierzustand wird somit bei Drehung der Motorspindel das Starting from the blocking state is thus upon rotation of the motor spindle the
Kupplungselement gegen die Spannung des Federelements axial verschoben und gibt das Verbindungsmittel frei, welches durch Drehung des Kerns ins Gehäuse gedrückt werden kann, sodass der Freigabezustand erreicht ist. Um zurück zum Blockierzustand zu gelangen, wird die Motorspindel in die andere Richtung gedreht, sodass das Clutch element axially displaced against the tension of the spring element and releases the connecting means, which can be pressed by rotation of the core into the housing, so that the release state is reached. To get back to the blocking state, the motor spindle is rotated in the other direction, so that the
Kupplungselement axial zurück verschoben wird und das Verbindungsmittel wieder zurück ins Gehäuse drückt. Clutch element is moved back axially and pushes the connecting means back into the housing.
Erfindungsgemäß kann vorgesehen sein, dass der Kern mit einer Schließvorrichtung, beispielsweise einem Schließhebel verbunden ist, sodass die Schließvorrichtung im Freigabezustand durch Drehung des Kerns betätigbar ist, und im Blockierzustand nicht betätigbar ist. Eine derartige Ausführungsform kann insbesondere bei Hebelzylindern vorgesehen sein, die nur von einer Seite betätigt werden. According to the invention it can be provided that the core is connected to a closing device, for example a closing lever, so that the closing device can be actuated in the release state by rotation of the core, and can not be actuated in the blocking state. Such an embodiment may be provided in particular with lever cylinders, which are actuated only from one side.
Erfindungsgemäß kann vorgesehen sein, dass das Kupplungselement als According to the invention it can be provided that the coupling element as
Kupplungsring ausgeführt ist, der an seinem äußeren Umfang eine nach außen abstehende, in einer Kernnut des Kerns im Wesentlichen axial geführte Schulter umfasst. Dadurch wird erreicht, dass der Kupplungsring nur in axialer Richtung beweglich ist. Die erfindungsgemäße Eingriffsfläche kann vorzugsweise an der Außenfläche dieser Schulter vorgesehen sein und dort mit dem Verbindungsmittel erfindungsgemäß zusammenwirken. Insbesondere kann in der Kernnut eine Ausnehmung vorgesehen sein, durch die das Verbindungsmittel durchführbar ist, um den Formschluss des Kerns mit dem Gehäuse herzustellen. Coupling ring is executed, which comprises at its outer periphery an outwardly projecting, in a core groove of the core substantially axially guided shoulder. This ensures that the coupling ring is movable only in the axial direction. The engagement surface according to the invention may preferably be provided on the outer surface of this shoulder and cooperate there according to the invention with the connecting means. In particular, a recess may be provided in the core groove, through which the connecting means can be performed in order to produce the positive connection of the core with the housing.
Erfindungsgemäß kann vorgesehen sein, dass das Verbindungsmittel als Kugel ausgeführt ist, die zur Bildung des Blockierzustands durch eine vorzugsweise According to the invention it can be provided that the connecting means is designed as a ball, which is to form the blocking state by a preferably
kreisförmige Ausnehmung des Kerns in eine Gehäusenut des Gehäuses drückbar ist. Die Ausnehmung des Kerns kann insbesondere in der Kernnut des Kerns vorgesehen sein, sodass die in der Kernnut geführte Schulter des Kupplungsrings dazu ausgeführt ist, die Kugel durch die Ausnehmung des Kerns in die Gehäusenut zu drucken. Im Blockierzustand befindet sich die Kugel teils in der Kernnut und teils in der Gehäusenut, sodass eine formschlüssige Verbindung zwischen Kern und Gehäuse erreicht wird. circular recess of the core can be pressed into a housing groove of the housing. The recess of the core may in particular be provided in the core groove of the core, so that the guided in the core groove shoulder of the coupling ring is adapted to print the ball through the recess of the core in the housing groove. In the blocking state, the ball is partly in the core groove and partly in the housing groove, so that a positive connection between the core and the housing is achieved.
Ein erfindungsgemäßer Vorteil der Realisierung des Verbindungsmittels als Kugel besteht auch darin, dass im Freigabezustand keine Rückstellmittel erforderlich sind, um die Kugel zurück in den Kern zu bewegen: Das bei manueller Betätigung des Knaufs auf den Kern ausgeübte Drehmoment reicht aus, um die Kugel durch die Kante der Gehäusenut in den Kern zurück zu verschieben. An inventive advantage of the realization of the connecting means as a ball also consists in that in the release state no return means are required to move the ball back into the core: The force exerted on the core by manual actuation of the knob torque is sufficient to the ball through the Edge of the housing groove to move back into the core.
Erfindungsgemäß kann vorgesehen sein, dass das Kupplungselement an seinem äußeren Umfang, vorzugsweise am äußeren Umfang der Schulter, eine sich gegenüber der Längsachse im Wesentlichen kreisbogenförmig erweiternde Anschlagsfläche aufweist. Diese Anschlagsfläche kann insbesondere steiler sein als die Eingriffsfläche und bildet einen Anschlag für das Verbindungsmittel, sodass das Kupplungselement nicht weiter bewegt werden kann. Bei der Verwendung einer Kugel als According to the invention, it can be provided that the coupling element has on its outer circumference, preferably on the outer circumference of the shoulder, an abutment face that widens in a substantially arcuate manner with respect to the longitudinal axis. This stop surface may in particular be steeper than the engagement surface and forms a stop for the connecting means, so that the coupling element can not be moved further. When using a ball as
Verbindungsmittel kann erfindungsgemäß vorgesehen sein, dass der Radius des Kreisbogens im Wesentlichen dem Radius der Kugel entspricht. Connecting means may be provided according to the invention that the radius of the circular arc substantially corresponds to the radius of the ball.
Die Eingriffsfläche kann direkt in die Anschlagsfläche übergehen, es kann aber auch vorgesehen sein, dass zwischen der Eingriffsfläche und der Anschlagsfläche eine im Wesentlichen äquidistant zur Längsachse verlaufende Distanzfläche gebildet ist. Dadurch wird ein konstruktionsbedingtes Spiel in der Position des Kupplungselements im Blockierzustand ermöglicht. The engagement surface can pass directly into the abutment surface, but it can also be provided that between the engagement surface and the abutment surface a substantially equidistant from the longitudinal axis extending spacer surface is formed. This allows a design-related game in the position of the coupling element in the blocking state.

Dies hat den Vorteil, dass die im Blockierzustand auf den Kern wirkenden Drehmomente gleichmäßig auf das Gehäuse abgeleitet werden. The connecting means may be arranged distributed substantially uniformly on the outer circumference of the core. This has the advantage that the torque acting in the blocking state on the core are uniformly dissipated to the housing.

Die Kernnuten weisen vorzugsweise jeweils Ausnehmungen zur Durchführung der Verbindungsmittel in entsprechende Gehäusenuten auf, um den Formschluss in den verschiedenen Winkelstellungen des Kerns herstellen zu können. This ensures that the core in several angular positions, preferably in four rotated by 90 ° angular positions, can be performed in the blocking state. The core grooves preferably each have recesses for the passage of the connecting means in corresponding housing grooves in order to produce the positive connection in the different angular positions of the core can.
Erfindungsgemäß kann vorgesehen sein, dass zur Verbindung des Kerns mit einem Betätigungselement, beispielsweise einer Sperrnase, ein separates Koppelelement vorgesehen ist, das zum formschlüssigen Eingriff in Ausnehmungen des According to the invention it can be provided that for connecting the core with an actuating element, for example a locking lug, a separate coupling element is provided, which for positive engagement in recesses of the
Betätigungselements ausgeführt ist. Dies hat den Vorteil, dass verschiedene Adapter zur Betätigung unterschiedlicher Sperrnasen eingesetzt werden können, und der Kern somit nicht für jede Sperrnase anders gefertigt werden muss. Actuator is executed. This has the advantage that different adapters can be used to operate different locking lugs, and the core thus does not have to be made differently for each locking lug.
Um ein erfindungsgemäß besonders vorteilhaftes Zusammenwirken mit dem To a particularly advantageous according to the invention interaction with the
Kupplungselement zu ermöglichen, kann erfindungsgemäß vorgesehen sein, dass das Koppelelement mit dem Kupplungselement in federnder Verbindung steht und ebenfalls im Wesentlichen entlang der Längsachse des Kerns verschiebbar ist. Erfindungsgemäß kann vorgesehen sein, dass das Koppelelement zur im Wesentlichen axialen Verschiebung entlang der Längsachse des Kerns über das oben beschriebene Federelement, vorzugsweise über eine Spiralfeder, mit einer an einer Motorspindel eines Motors drehfest angeordneten Motormutter verbunden ist. Das Federelement steht in diesem Fall sowohl mit dem Kupplungselement, mit dem Koppelelement, als auch mit der Motormutter federnd in Verbindung.

According to the invention it can be provided that the coupling element for substantially axial displacement along the longitudinal axis of the core via the spring element described above, preferably via a coil spring, is connected to a motor nut of a motor rotatably mounted motor nut. In this case, the spring element is resiliently connected both to the coupling element, to the coupling element, and to the motor nut.
Dadurch wird das Koppelelement mit dem Kupplungselement verbunden und bewegt sich im Blockierzustand im Wesentlichen synchron mit dem Kupplungselement. As a result, the coupling element is connected to the coupling element and moves in the blocking state substantially synchronously with the coupling element.
Im Freigabezustand wird das Koppelelement jedoch gegen das Betätigungselement gedrückt und verharrt in dieser Position, sofern es nicht formschlüssig in In the release state, however, the coupling element is pressed against the actuating element and remains in this position, unless it is positively in
Ausnehmungen des Betätigungselements eingreift. Das Betätigungselement ist in dieser Situation nicht eingerastet und frei drehbar - eine Betätigung der Sperrnase ist nicht möglich. Diese Situation wird als Freilauf bezeichnet. Erst wenn durch Drehen des Knaufs das Koppelelement in eine Stellung gebracht wird, in der es in das Recesses of the actuating element engages. The actuator is not engaged in this situation and freely rotatable - an actuation of the locking lug is not possible. This situation is called freewheeling. Only when the coupling element is brought into a position by turning the knob, in which it in the
Betätigungselement formschlüssig einrastet, kann das Betätigungselement betätigt werden. Diese Situation wird als eingerasteter Zustand bezeichnet. Actuator engages positively, the actuator can be actuated. This situation is called a locked state.
Erfindungsgemäß kann vorgesehen sein, dass das Federelement als einstückige Spiralfeder mit einer Außenspirale und einer Innenspirale ausgeführt ist, wobei ein Ende der Außenspirale mit dem Kupplungselement, und die Innenspirale mit der Motormutter in Verbindung steht. Sofern ein Koppelelement vorgesehen ist, kann vorgesehen sein, dass die Außenspirale an ihrem anderen Ende mit dem Koppelelement verbunden ist.

If a coupling element is provided, it can be provided that the outer spiral is connected at its other end to the coupling element.
Dies erlaubt eine besonders effiziente und modulare Ausführung des This allows a particularly efficient and modular execution of the
erfindungsgemäßen Kupplungssystems, da lediglich ein zusätzliches Teil, nämlich das Koppelelement, erforderlich ist, und das Federelement sowie das Kuppelelement und das Verbindungsmittel weiterverwendet werden kann. coupling system according to the invention, since only an additional part, namely the coupling element is required, and the spring element and the coupling element and the connecting means can be used.

Fig. 1 zeigt eine schematische Explosionsdarstellung einer ersten Ausführungsform eines erfindungsgemäßen Kupplungssystems für ein elektromechanisches Schloss. Auf der linken Seite dieser Darstellung ist ein herkömmlicher Handknauf dargestellt, der mit dem Kern 1 in Verbindung steht. Der Kern 1 ist im Gehäuse 2 drehbar gelagert. Im Ruhezustand befindet sich das Kupplungssystem im Blockierzustand, sodass der Benutzer durch Drehen des Handknaufs keine Drehung des Kerns 1 gegenüber dem Gehäuse 2 bewirken kann. Im Freigabezustand gibt das Kupplungssystem den Kern 1 frei und der Benutzer kann durch Drehen des Handknaufs eine Drehung des Kerns 1 gegenüber dem Gehäuse 2 bewirken. Im Kern 1 ist ein Kupplungselement in Form eines Kupplungsrings 3 sowie ein Federelement in Form einer Spiralfeder 9 Fig. 1 shows a schematic exploded view of a first embodiment of a coupling system according to the invention for an electromechanical lock. On the left side of this illustration, a conventional hand knob is shown, which is in communication with the core 1. The core 1 is rotatably mounted in the housing 2. At rest, the coupling system is in the locked state, so that the user can not cause rotation of the core 1 relative to the housing 2 by turning the hand knob. In the release state, the coupling system releases the core 1 and the user can effect rotation of the core 1 relative to the housing 2 by turning the hand knob. In the core 1 is a coupling element in the form of a coupling ring 3 and a spring element in the form of a coil spring. 9
angeordnet. Zur formschlüssigen Verbindung des Kerns 1 mit dem Gehäuse 2 dienen Verbindungsmittel in Form von zwei Kugeln 4. arranged. For positive connection of the core 1 with the housing 2 serve connecting means in the form of two balls. 4
Fig. 2a zeigt einen Querschnitt durch diese Ausführungsform im Blockierzustand. Das erfindungsgemäße Kupplungssystem wird in diesem Fall für ein Hebelzylinderschloss verwendet. Der in dieser Figur dargestellte Blockierzustand stellt den Ruhezustand des Schlosses dar. Das Kupplungssystem umfasst ein Gehäuse 2 und einen darin drehbar gelagerten Kern 1 , der auf der linken Seite mit einem Handknauf verbunden ist. Auf der rechten Seite ist der Kern 1 mit einem Schließhebel 24 verbunden. Es sind zwei Kugeln 4 vorgesehen, die durch eine kreisförmige Ausnehmung 17 des Kerns 1 in Fig. 2a shows a cross section through this embodiment in the blocking state. The coupling system according to the invention is used in this case for a lever cylinder lock. The blocking state shown in this figure represents the resting state of the lock. The coupling system comprises a housing 2 and a rotatably mounted therein core 1, which is connected on the left side with a hand knob. On the right side of the core 1 is connected to a closing lever 24. There are two balls 4 provided by a circular recess 17 of the core 1 in
Gehäusenuten 16 des Gehäuses 2 gedrückt sind. Zu diesem Zweck ist im Kern 1 ein Kupplungsring 3 vorgesehen, der entlang der Längsachse 23 des Kerns 1 verschiebbar ist. Der Kupplungsring 3 verfügt an seinem äußeren Umfang über zwei radial nach außen vorstehende Schultern 12, die zur Führung jeweils in eine Kernnut 13 des Kerns 1 eingreifen. Im dargestellten Blockierzustand sind die Kugeln 4 durch die Anschlagsfläche 1 1 am äußeren Umfang des Kupplungsrings 3 durch die Ausnehmung 17 in die Gehäusenut 16 gepresst und stellen eine formschlüssige Verbindung des Kerns 1 mit dem Gehäuse 2 sicher. Eine Drehung des Kerns 1 gegenüber dem Gehäuse 2 ist nicht möglich. Housing grooves 16 of the housing 2 are pressed. For this purpose, a coupling ring 3 is provided in the core 1, which is displaceable along the longitudinal axis 23 of the core 1. The coupling ring 3 has at its outer periphery via two radially outwardly projecting shoulders 12, which engage in each case in a core groove 13 of the core 1 for guiding. In the illustrated blocking state, the balls 4 are pressed by the abutment surface 1 1 on the outer circumference of the coupling ring 3 through the recess 17 in the housing groove 16 and provide a positive connection of the core 1 with the housing 2 safe. A rotation of the core 1 relative to the housing 2 is not possible.
Um das Kupplungssystem in den Freigabezustand überzuführen, muss der To transfer the clutch system into the release state, the
Kupplungsring 3 nach rechts verschoben werden. Zu diesem Zweck ist der Coupling ring 3 are moved to the right. For this purpose, the
Kupplungsring 3 über eine Spiralfeder 9 mit einer Motormutter 8 verbunden, die an einer Motorspindel 6 eines im Kern 1 angeordneten Motors 7 drehfest angeordnet ist. Durch Aktivierung des Motors 7, beispielsweise durch eine berechtigte elektronische Chipkarte oder einen berechtigten RFI D-Chip, erfolgt eine Drehung der Motorspindel 6. Dadurch wird die Motormutter 8 entlang der Längsachse 23 nach rechts bewegt und zieht die Spiralfeder 9 ebenfalls nach rechts. Der Kupplungsring 3 ist an seinem inneren Umfang über ein Innengewinde 25 mit der Spiralfeder 9 verbunden und wird somit ebenfalls nach rechts verschoben, bis der Freigabezustand erreicht ist. Coupling ring 3 is connected via a coil spring 9 with a motor nut 8, which is arranged rotatably on a motor spindle 6 of a motor arranged in the core 1 7. By activating the motor 7, for example by an authorized electronic chip card or a legitimate RFI D chip, the motor spindle 6 is rotated. As a result, the motor nut 8 is moved to the right along the longitudinal axis 23 and also pulls the coil spring 9 to the right. The coupling ring 3 is connected at its inner periphery via an internal thread 25 with the coil spring 9 and is thus also displaced to the right until the release state is reached.
Fig. 2b zeigt einen Querschnitt durch diese Ausführungsform, wenn der Fig. 2b shows a cross section through this embodiment, when the
Freigabezustand erreicht ist. Die Motorspindel 6 hat durch Drehung die Motormutter 8 nach rechts verschoben und die Spiralfeder 9 sowie den Kupplungsring 3 Release state is reached. The motor spindle 6 has moved by rotation, the motor nut 8 to the right and the coil spring 9 and the coupling ring. 3
mitgenommen. Der Kupplungsring gibt an seiner äußeren Oberfläche die Kugeln 4 frei, und diese können entlang der konischen Eingriffsfläche 5 in den Kern 1 bewegt werden. Durch Verwendung der Kugeln 4 als Verbindungsmittel ist es nicht erforderlich, für die Verbindungsmittel ein Rückstellmittel vozusehen, da bei Drehung des Kerns 1 die Kugeln 4 durch die Kanten der Gehäusenut 1 6 zwangsläufig ins Innere des Kerns 1 gedrückt werden. Eine Drehung des Kerns 1 gegenüber dem Gehäuse 2 ist somit möglich, sodass durch Betätigung des Handknaufs der Schließhebel 24 verdreht werden kann. In diesem Zustand ist die Spiralfeder 9 gespannt und liegt rechts am Schließhebel 24 an, sodass eine Kraft auf den Kupplungsring 3 ausgeübt wird. taken. The coupling ring releases on its outer surface the balls 4, and these can be moved along the conical engagement surface 5 in the core 1. By using the balls 4 as connecting means, it is not necessary to provide a return means for the connecting means, since upon rotation of the core 1, the balls 4 are forcibly pushed into the interior of the core 1 by the edges of the housing groove 1 6. A rotation of the core 1 relative to the housing 2 is thus possible, so that the closing lever 24 can be rotated by actuation of the hand knob. In this state, the coil spring 9 is stretched and is right on the closing lever 24, so that a force is exerted on the coupling ring 3.
In der Regel wird der Freigabezustand nur für eine bestimmte Zeitspanne, In general, the release state only for a certain period of time,
beispielsweise einige Sekunden, aufrechterhalten, um sicherzustellen, dass eine for example, a few seconds, to ensure that one
Betätigung des Schließhebels nur für eine kurze Zeit erfolgen kann. Danach dreht der Motor 7 die Motorspindel 6 in die Gegenrichtung und die Motormutter 8 zieht über die Spiralfeder 9 den Kupplungsring 3 wieder nach links in den Actuation of the closing lever can only be done for a short time. Thereafter, the motor 7 rotates the motor spindle 6 in the opposite direction and the motor nut 8 pulls on the coil spring 9, the coupling ring 3 again to the left in the
Blockierzustand gemäß Fig. 2a. Durch Übergang vom Freigabezustand in den Blocking state according to FIG. 2a. By transition from the release state into the
Blockierzustand wird die Spiralfeder 9 wieder entspannt. Blocking state, the coil spring 9 is relaxed again.

Ausführungsform des erfindungsgemäßen Kupplungselements in Form eines Embodiment of the coupling element according to the invention in the form of a
Kupplungsrings 3. Der Kupplungsring 3 weist an seinem äu ßeren Umfang zwei nach außen abstehende, im Wesentlichen halbzylinderförmige Schultern 12 auf. An seinem inneren Umfang ist ein Innengewinde 25 vorgesehen, welches dazu dient, ein Ende der Spiralfeder 9 mit dem Kupplungsring 3 zu verbinden. Die Schultern 12 umfassen an ihrer äußeren Oberfläche eine Eingriffsfläche 5, eine Distanzfläche 10 und eine Coupling ring 3. The coupling ring 3 has on its externa ßeren circumference two outwardly projecting, substantially semi-cylindrical shoulders 12. At its inner circumference, an internal thread 25 is provided, which serves to connect one end of the coil spring 9 with the coupling ring 3. The shoulders 12 comprise on their outer surface an engagement surface 5, a spacer surface 10 and a
Anschlagsfläche 1 1 . Stop surface 1 1.
Die Eingriffsfläche 5 ist gegenüber der Längsachse 23 und somit auch gegenüber der Längsachse des Kupplungsrings 3 konisch nach außen erweitert, um die oben beschriebene Zusammenwirkung mit den Verbindungsmitteln zu erreichen. Der Winkel der Eingriffsfläche 5 gegenüber der Längsachse 23 beträgt etwa 20°. Anschließend an die Eingriffsfläche 5 ist eine Distanzfläche 10 vorgesehen, deren Querschnitt im The engagement surface 5 is widened conically outward with respect to the longitudinal axis 23 and thus also with respect to the longitudinal axis of the coupling ring 3 in order to achieve the above-described interaction with the connection means. The angle of the engagement surface 5 with respect to the longitudinal axis 23 is about 20 °. Subsequent to the engagement surface 5, a spacer surface 10 is provided, whose cross-section in
Wesentlichen parallel zur Längsachse 23 verläuft. Schließlich geht die Distanzfläche 10 in eine Anschlagsfläche 1 1 über, die sich kreisbogenförmig nach außen erweitert. Der Radius des Kreisbogens entspricht etwa dem Radius der Kugeln 4. Dadurch wird erreicht, dass die Kugeln 4 sicher in der Anschlagsfläche gehalten werden. Substantially parallel to the longitudinal axis 23 extends. Finally, the spacer surface 10 passes into a stop surface 1 1, which widens in a circular arc outward. The radius of the circular arc corresponds approximately to the radius of the balls 4. This ensures that the balls 4 are held securely in the stop surface.

Der Kern 1 ist im Wesentlichen zylindrisch und hat eine Ausnehmung zur Aufnahme des Motors 7 und des Kupplungssystems selbst. Am innneren Umfang der Ausnehmung sind vier Kernnuten 13 jeweils etwa 90° zueinander versetzt angeordnet. Die Kernnuten 13 dienen zur Führung der Schultern 12 des Kupplungsrings 3. In den Kernnuten 13 sind kreisförmige Ausnehmungen 17 zur Durchführung der Kugeln 4 vorgesehen. Fig. 2f zeigt eine schematische Ansicht einer Spiralfeder 9 für diese Ausführungsform des erfindungsgemäßen Kupplungssystems. Die Spiralfeder 9 ist einstückig und umfasst eine Außenspirale 14 und eine Innenspirale 15. Ein Ende der Außenspirale 14 ist mit dem Kupplungsring 3 verbunden, beispielsweise in das Innengewinde 25 eingeschraubt und gegebenenfalls auch punktuell angeschweißt. Die Innenspirale 15 ist mit der Motormutter 8 verbunden, sodass eine Bewegung der Motormutter 8 federnd an den Kupplungsring 3 übertragen wird. Fig. 2e shows a schematic view of a core 1 for this embodiment of the coupling system according to the invention. The core 1 is substantially cylindrical and has a recess for receiving the motor 7 and the coupling system itself. At the inner periphery of the recess four core grooves 13 are each offset approximately 90 ° to each other. The core grooves 13 serve to guide the shoulders 12 of the coupling ring 3. In the core grooves 13 circular recesses 17 for the implementation of the balls 4 are provided. Fig. 2f shows a schematic view of a coil spring 9 for this embodiment of the coupling system according to the invention. The coil spring 9 is in one piece and comprises an outer coil 14 and an inner coil 15. One end of the outer coil 14 is connected to the coupling ring 3, for example, screwed into the internal thread 25 and possibly also selectively welded. The inner coil 15 is connected to the motor nut 8, so that a movement of the motor nut 8 is resiliently transmitted to the coupling ring 3.

Das Gehäuse 2 ist im Wesentlichen zylindrisch und weist eine exzentrisch angeordnete kreisförmige Ausnehmung zur Aufnahme des Kerns 1 auf. Am inneren Umfang des Gehäuses 2 sind vier Fig. 2g shows a schematic view of a housing 2 for this embodiment of the coupling system according to the invention. The housing 2 is substantially cylindrical and has an eccentrically arranged circular recess for receiving the core 1. At the inner periphery of the housing 2 are four
Gehäusenuten 16 jeweils etwa 90° zueinander versetzt angeordnet. Die Gehäusenuten 16 dienen zur Aufnahme der Kugeln 4. In diesem Ausführungsbeispiel weisen die Gehäusenuten 16 abgerundete Kanten auf, um sicherzustellen, dass im Housing grooves 16 each offset approximately 90 ° to each other. The housing grooves 16 serve to receive the balls 4. In this embodiment, the housing grooves 16 have rounded edges to ensure that in

Das Kupplungssystem umfasst ein Gehäuse 2 und einen darin drehbar gelagerten Kern 1 , der auf der linken Seite mit einem Fig. 3 shows a schematic exploded view of a second embodiment of a coupling system according to the invention for an electromechanical lock. On the left side of this illustration, a conventional hand knob is shown, which is in communication with the core 1. The core 1 is rotatably mounted in the housing 2. At rest, the coupling system is in the locked state, so that the user can not cause rotation of the core 1 relative to the housing 2 by turning the hand knob. In the release state, the coupling system releases the core 1 and the user can effect rotation of the core 1 relative to the housing 2 by turning the hand knob. In the core 1 is a coupling element in the form of a coupling ring 3, a spring element in the form of a coil spring 9, and a coupling element 18 is arranged for engagement in a locking lug 19. For positive connection of the core 1 with the housing 2 serve connecting means in the form of two balls. 4 Fig. 4a shows a cross section through this embodiment in the blocking state. The coupling system according to the invention is used in this case for a cylinder lock with a locking lug 19. The blocking state shown in this figure represents the resting state of the lock. The coupling system comprises a housing 2 and a rotatably mounted therein core 1, which on the left side with a
Handknauf verbunden ist. Auf der rechten Seite ist der Kern 1 mit der Sperrnase 19 verbunden. Hand knob is connected. On the right side of the core 1 is connected to the locking lug 19.
Es sind zwei Kugeln 4 vorgesehen, die durch eine kreisförmige Ausnehmung 17 des Kerns 1 in Gehäusenuten 16 des Gehäuses 2 gedrückt sind. Zu diesem Zweck ist im Kern 1 ein Kupplungsring 3 vorgesehen, der entlang der Längsachse 23 des Kerns 1 verschiebbar ist. Der Kupplungsring 3 ist identisch zum Ausführungsbeispiel der Fig. 2a ausgeführt und verfügt an seinem äußeren Umfang über zwei radial nach außen vorstehende Schultern 12, die zur Führung jeweils in eine Kernnut 13 des Kerns 1 eingreifen. Im dargestellten Blockierzustand sind die Kugeln 4 durch die There are two balls 4 are provided, which are pressed by a circular recess 17 of the core 1 in the housing grooves 16 of the housing 2. For this purpose, a coupling ring 3 is provided in the core 1, which is displaceable along the longitudinal axis 23 of the core 1. The coupling ring 3 is identical to the embodiment of Fig. 2a executed and has at its outer periphery via two radially outwardly projecting shoulders 12, which engage for guiding in each case in a core groove 13 of the core 1.

Um das Kupplungssystem in den Freigabezustand überzuführen, muss der To transfer the clutch system into the release state, the
Kupplungsring 3 nach rechts verschoben werden. Zu diesem Zweck ist der Coupling ring 3 are moved to the right. For this purpose, the
Kupplungsring 3 über eine Spiralfeder 9 mit einer Motormutter 8 verbunden, die an einer Motorspindel 6 eines im Kern 1 angeordneten Motors 7 drehfest angeordnet ist. Coupling ring 3 is connected via a coil spring 9 with a motor nut 8, which is arranged rotatably on a motor spindle 6 of a motor arranged in the core 1 7.
Durch Aktivierung des Motors 7, beispielsweise durch eine berechtigte elektronische Chipkarte oder einen berechtigten RFI D-Chip, erfolgt eine Drehung der Motorspindel 6. Dadurch wird die Motormutter 8 entlang der Längsachse 23 nach rechts bewegt und zieht die Spiralfeder 9 ebenfalls nach rechts. Der Kupplungsring 3 ist an seinem inneren Umfang über ein Innengewinde 25 mit der Spiralfeder 9 verbunden und wird somit ebenfalls nach rechts verschoben, bis der Freigabezustand erreicht ist. Im Unterschied zum Ausführungsbeispiel als Hebelzylinderschloss gemäß Fig. 2a ist in diesem Fall die Spiralfeder 9 am zweiten Ende der Au ßenspirale 14 über ein By activating the motor 7, for example by an authorized electronic chip card or a legitimate RFI D chip, the motor spindle 6 is rotated. As a result, the motor nut 8 is moved to the right along the longitudinal axis 23 and also pulls the coil spring 9 to the right. The coupling ring 3 is connected at its inner periphery via an internal thread 25 with the coil spring 9 and is thus also displaced to the right until the release state is reached. In contrast to the embodiment as a lever cylinder lock according to Fig. 2a in this case, the coil spring 9 at the second end of the Au ßenspirale 14 via a
Innengewinde 22 mit einem Koppelelement 18 verbunden. Das Koppelelement 18 dient zum formschlüssigen Eingriff in entsprechende Ausnehmungen der Sperrnase 19. Internal thread 22 connected to a coupling element 18. The coupling element 18 is used for positive engagement in corresponding recesses of the locking lug 19th
Dabei wird berücksichtigt, dass die Position der Sperrnase 19 in der Regel, It is considered that the position of the locking lug 19 usually,
insbesondere bei beidseitig betätigbaren Schlössern, nicht sichergestellt werden kann. especially with both sides actuated locks, can not be ensured.
Das Koppelelement 18 steht in federnder Verbindung mit dem Kupplungsring 3 und der Motormutter 8 und ist ebenfalls entlang der Längsachse 23 verschiebbar. Im The coupling element 18 is in resilient connection with the coupling ring 3 and the motor nut 8 and is also displaceable along the longitudinal axis 23. in the
dargestellten Blockierzustand ist die Spiralfeder 9 entspannt und das Koppelelement greift nicht in die Sperrnase 19 ein. Die Sperrnase 19 ist somit frei drehbar. shown blocking state, the coil spring 9 is relaxed and the coupling element does not engage in the locking lug 19 a. The locking lug 19 is thus freely rotatable.
Fig. 4b zeigt einen Querschnitt durch diese Ausführungsform, wenn der Fig. 4b shows a cross section through this embodiment when the
Freigabezustand erreicht ist. Die Motorspindel 6 hat durch Drehung die Motormutter 8 nach rechts verschoben und die Spiralfeder 9 sowie den Kupplungsring 3 Release state is reached. The motor spindle 6 has moved by rotation, the motor nut 8 to the right and the coil spring 9 and the coupling ring. 3

In diesem Zustand ist die Spiralfeder 9 gespannt. Das Koppelelement 18 greift jedoch noch nicht in die vorgesehenen Ausnehmungen der Sperrnase 19 ein, sondern liegt an diesem an, sodass über die gespannte Spiralfeder 9 eine Kraft auf den Kupplungsring 3 ausgeübt wird. taken. The coupling ring releases on its outer surface the balls 4, and these can be moved along the conical engagement surface 5 in the core 1. In this state, the coil spring 9 is tensioned. However, the coupling element 18 does not yet engage in the provided recesses of the locking lug 19, but is applied to this, so that on the tensioned coil spring 9, a force is exerted on the coupling ring 3.
Eine Drehung des Kerns 1 gegenüber dem Gehäuse 2 ist in dieser Position möglich, sodass durch Betätigung des Handknaufs das Koppelelement 18 in jene Position bewegt werden kann, in der es in die vorgesehenen Ausnehmungen der Sperrnase 19 einrasten kann. In der Regel muss dazu eine Drehung des Handknaufs um maximal 90° erfolgen. A rotation of the core 1 relative to the housing 2 is possible in this position, so that by actuation of the hand knob, the coupling element 18 can be moved to that position in which it can engage in the provided recesses of the locking lug 19. As a rule, the hand knob must be turned by a maximum of 90 °.
Fig. 4c zeigt einen Querschnitt durch diese zweite Ausführungsform im eingerasteten Zustand. Das Koppelelement 18 ist gänzlich nach rechts verschoben und in die Fig. 4c shows a cross section through this second embodiment in the locked state. The coupling element 18 is moved completely to the right and in the
Sperrnase 19 eingerastet. Eine Betätigung der Sperrnase 19 durch Drehen des Locking lug 19 engaged. An actuation of the locking lug 19 by turning the
Handknaufs ist somit möglich. Der Freigabezustand und eingerastete Zustand wird in der Regel nur für eine bestimmte Zeitspanne, beispielsweise einige Sekunden, aufrechterhalten, um sicherzustellen, dass eine Betätigung der Sperrnase nur für eine kurze Zeit erfolgen kann. Danach dreht der Motor 7 die Motorspindel 6 in die Gegenrichtung und die Motormutter 8 zieht über die Spiralfeder 9 den Kupplungsring 3 wieder nach links. Dadurch wird auch das Hand knob is thus possible. The release state and locked state is usually maintained only for a certain period of time, for example a few seconds, to ensure that actuation of the locking lug can only take place for a short time. Thereafter, the motor 7 rotates the motor spindle 6 in the opposite direction and the motor nut 8 pulls the coupling ring 3 again to the left via the coil spring 9. This will also do that
