Abstract

The actuator has a motor (4), an electronic circuit, and a locking device (18, 9). At least one locking pin (6) can be locked in a locking position with the locking device (18, 9). The electronic circuit (E) has a trigger contact (A). Holding means (B) are provided to prevent the motor (4) from switching on too early following closing of the trigger contact (A) upon the removal of a key. Upon removal of the key, the electronic circuit is triggered in a first step and then the motor is switched on with a delay. In this manner, a jam of the locking device can be reliably prevented. In addition, opening can also be prevented.

Description

Aktuator für einen elektromechanischen Drehschliesszylinder und einen elektromechanischen Drehschliesszylinder mit einem solchen Aktuator Actuator for an electromechanical rotary lock cylinder and an electromechanical rotary lock cylinder with such an actuator
Die Erfindung betrifft einen Aktuator für einen elektromechanischen Drehschliesszylinder, mit einem Motor, einer elektronischen Schaltung und einer Sperrvorrichtung, mit welcher wenigstens ein Sperrstift in einer Sperrposition sperrbar ist, wobei die elektronische Schaltung einen Weckkontakt aufweist. Die Erfindung betrifft zudem einen elektromechanischen Drehschliesszylinder.The invention relates to an actuator for an electromechanical rotary lock cylinder, comprising a motor, an electronic circuit and a locking device, with which at least one locking pin can be blocked in a blocking position, wherein the electronic circuit has a wake-up contact. The invention also relates to an electromechanical rotary lock cylinder.
Ein Aktuator dieser Gattung sowie ein elektromechanischer Drehschliesszylinder mit einem solchen Aktuator ist in der Internationalen Patentanmeldung PCT/CH 2006/000695 vom 13. Dezember 2006 des Anmelders offenbart. Der Drehschliesszylinder besitzt wie üblich einen Stator und einen Rotor sowie Zuhaltungen. Zusätzlich zu den Zuhaltungen besitzt der Drehschliesszylinder zwei Sperrstifte, die in der Sperrstellung durch den Aktuator gesperrt sind, so dass diese Sperrstifte erst dann zur Freigabe des Motors bewegt werden können, wenn der Aktuator diese frei gibt. Beim Einsetzen eines Schlüssels in den Schlüsselkanal des Drehschliesszylinders wird durch den Schlüssel ein Drückerorgan nach unten bewegt und die Sperrstifte werden durch eine Feder dadurch vorgespannt. Die Sperrstifte können jedoch noch nicht bewegt werden, das sie wie erwähnt gesperrt sind. Wir der Schlüssel von der elektronischen Schaltung nach dem Lesen eines Codes als berechtigt erkannt, so gibt der Aktuator die Sperrstifte frei. Infolge der Vorspannung durch das Drückerorgan werden die Sperrstifte in eine freigebende Position bewegt, so dass der Rotor gedreht und das Schloss geöffnet werden kann. Die elektronische Schaltung fällt nach dem Betätigen des Motors sofort wieder in einen "sleep modus". Wird der Schlüssel abgezogen, so geht das Drückerorgan durch die Wirkung einer weiteren Feder nach oben in die Ausgangsstellung. Über einen Weckkontakt wird die elektronische Schaltung geweckt und der Motor aktiviert, der hierauf die Sperrstifte wieder sperrt.An actuator of this type and an electromechanical rotary lock cylinder with such an actuator is disclosed in the applicant's international patent application PCT / CH 2006/000695 of December 13, 2006. The rotary lock cylinder has as usual a stator and a rotor and tumblers. In addition to the tumblers the rotary lock cylinder has two locking pins which are locked in the locked position by the actuator, so that these locking pins can only be moved to release the motor when the actuator releases them. Upon insertion of a key in the keyway of the rotary lock cylinder, a pusher member is moved downwardly by the key and the lock pins are biased by a spring therethrough. However, the locking pins can not be moved, they are locked as mentioned. If the key is recognized as authorized by the electronic circuit after reading a code, the actuator releases the locking pins. Due to the biasing by the pusher member, the locking pins are moved to a releasing position so that the rotor can be rotated and the lock can be opened. The electronic circuit immediately falls back into a "sleep mode" after the motor has been actuated. Will the key subtracted, the presser member goes through the action of another spring upwards into the starting position. A wake-up contact wakes up the electronic circuit and activates the motor, which then locks the locking pins again.
Der Erfindung liegt die Aufgabe zu Grunde, einen Aktuator der genannten Art zu schaffen, der noch robuster und funktionssicherer arbeitet und der trotzdem vergleichsweise kostengünstig hergestellt werden kann.The invention is based on the object to provide an actuator of the type mentioned, which works even more robust and reliable and can still be produced relatively inexpensively.
Die Aufgabe ist bei einem gattungsgemässen Aktuator dadurch gelöst, dass Haltemittel vorgesehen sind, die nach einem Schliessen des Weckkontaktes beim Abziehen eines Schlüssels ein verfrühtes Einschalten des Motors (4) verhindern. Beim Abziehen des Schlüssels wird somit in einem ersten Schritt die elektronische Schaltung aufgeweckt und dann verzögert der Motor eingeschaltet, um über die genannte Sperrvorrichtung den wenigstens einen Sperrstift wieder zu verriegeln. Damit kann auch bei sehr robuster und starrer Ausbildung des Aktuators vermieden werden, dass der Motor zu früh eingeschaltet wird und die Sperrvorrichtung verklemmt. Dadurch ist insbesondere eine starre und kompakte Ausführung möglich, die ein Aufklopfen verhindert.The object is achieved in a generic actuator characterized in that holding means are provided which prevent premature switching on the motor (4) after closing the wake-up contact when removing a key. When removing the key thus the electronic circuit is woken up in a first step and then delayed the motor is turned on to lock the at least one locking pin on said locking device again. This can be avoided even with very robust and rigid design of the actuator that the engine is turned on too early and jammed the locking device. As a result, in particular a rigid and compact design is possible, which prevents a knocking.
Die Haltemittel weisen gemäss einer Weiterbildung der Erfindung ein Kontaktelement auf, dass in der Sperrvorrichtung gelagert und mit dieser bewegt und insbesondere verschwenkbar ist. Das Kontaktelement bildet somit ein Schaltelement mit zwei Positionen. In der einen Position ist der Schalter geschlossen und in der anderen geöffnet.According to a development of the invention, the holding means have a contact element which is mounted in the blocking device and moved with it and in particular is pivotable. The contact element thus forms a switching element with two positions. In one position, the switch is closed and opened in the other.
Vorzugsweise ist das Kontaktelement an einem Sperrhebel gelagert, der mit dem genannten Sperrstift zusammenarbeitet um diesen zu sperren bzw. frei zu geben.Preferably, the contact element is mounted on a locking lever, which cooperates with said locking pin to lock or release it.
Nach einer Weiterbildung der Erfindung weist das Kontaktelement zwei Kontaktzungen auf, die in einer ersten Position zwei Kontakte der elektronischen Schaltung überbrücken und damit den Motor im genannten Ruhezustand halten und in einer zweiten Position die genannten Kontakte nicht überbrücken. Die erste Position ist die Halteposition und die zweite Position diejenige nach der genannten Zeitdauer.According to a development of the invention, the contact element has two contact tongues, which bridge in a first position two contacts of the electronic circuit and thus hold the engine in said quiescent state and do not bridge said contacts in a second position. The first position is the holding position and the second position is that after the said period of time.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Sperrvorrichtung einen schwenkbaren Sperrhebel und ein Zahnsegment aufweist, wobei das Zahnsegment zwischen dem Motor und dem Sperrhebel angeordnet ist, wobei der Sperrhebel in einer ersten Position den genannten wenigstens einen Sperrstift sperrt und in einer zweiten Position freigibt.According to a development of the invention it is provided that the locking device comprises a pivotable locking lever and a toothed segment, wherein the toothed segment is disposed between the motor and the locking lever, wherein the locking lever in a first position blocks said at least one locking pin and releases in a second position.
Die Erfindung betrifft zudem einen elektromechanischen Drehschliesszylinder mit einem Aktuator. Der Aktuator bildet mit einem Drückerorgan eine Einheit. Das Drückerorgan kann mit dem vorderen Ende eines Schlüssels zum Vorspannen des wenigstens einen Sperrstiftes nach unten bewegt werden. Der Aktuator hat hierbei lediglich die Funktion, den Sperrstift zu sperren bzw. frei zu geben. Die Energie zum Bewegen des Sperrstiftes wird vom Benutzer aufgebracht, indem er das Drückerorgan mit dem Schlüssel nach unten bewegt. Der Energieverbrauch zum Betrieb des Motors kann deshalb minimal gehalten werden. Eine Batterie, mit welcher der Motor gespiesen wird, kann eine entsprechend längere Lebensdauer aufweisen.The invention also relates to an electromechanical rotary lock cylinder with an actuator. The actuator forms a unit with a pusher member. The pusher member may be moved downwardly with the forward end of a key for biasing the at least one locking pin. The actuator here only has the function to lock or unlock the locking pin. The energy for moving the locking pin is applied by the user by moving the pusher member with the key down. The power consumption for operating the engine can therefore be minimized. A battery with which the motor is fed, can have a correspondingly longer life.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Weckkontakt mit einem Kontaktelement geschaltet wird, das mit dem Drückerorgan verbunden ist und mit diesem nach unten sowie nach oben bewegbar ist. Dieses Kontaktelement ist vorzugsweise so ausgebildet, dass es mit dem Schlüssel oder einem gesonderten Schlüssel kontaktierbar ist. Dieser Kontakt kann als Programmierkontakt, zur Notspeisung oder auch für andere Zwecke verwendet werden.According to a development of the invention it is provided that the wake-up contact is switched to a contact element which is connected to the trigger member and with this downward and upward movable. This contact element is preferably designed so that it can be contacted with the key or a separate key. This contact can be used as programming contact, for emergency supply or for other purposes.
Nach einer Weiterbildung der Erfindung ist der Weckkontakt auf einer ersten Leiterplatte und der Haltekontakt auf einer zweiten Leiterplatte angeordnet. Dies ermöglicht eine kostengünstige und dennoch funktionssichere Ausführung. Die erste Leiterplatte und/oder die zweite Leiterplatte sind in ein Gehäuse des Aktuators eingesetzt. Dies ermöglicht eine sehr einfache und dennoch präzise Positionierung der Leiterplatten bezüglich des Haltekontaktes.According to a development of the invention, the wake-up contact is arranged on a first printed circuit board and the holding contact is arranged on a second printed circuit board. This allows a cost-effective, yet reliable design. The first circuit board and / or the second circuit board are inserted into a housing of the actuator. This allows a very simple, yet precise positioning of the circuit boards with respect to the holding contact.

Die Figur 1 zeigt einen Aktuator 1, der ein Gehäuse 2 aufweist, das einen Gehäuseoberteil 2a und einen Gehäuseanteil 2b besitzt und in dem ein Elektromotor 4 gelagert ist. Die Speisung des Elektromotors 4 erfolgt beispielsweise über eine hier nicht gezeigte Batterie, die über Kontakte 5 mit dem Elektromotor 4 elektrisch verbunden ist. Im Gehäuse 2 ist zudem ein Drückerorgan 3 gelagert, das einen hinteren Teil 3 a und einen vorderen Teil 3b aufweist, die bei montiertem Aktuator 1 in den Schlüsselkanal eines hier nicht gezeigten elektromechanischen Drehschliesszylinders eingreifen. Mit diesem Drückerorgan 3 können zwei Sperrstifte 6 durch einschieben eines hier nicht gezeigten Schlüssels in den Schlüsselkanal vorgespannt werden. Mit einem Sperrhebel 9 können die beiden Sperrstifte 6 gemäss Figur 3 gesperrt werden, so dass sie beim Vorspannen in der ursprünglichen Position verbleiben. Zur Offenbarung des grundsätzlichen Aufbaues eines solchen Aktuators und eines elektromechanischen Drehschliesszylinders wird auf die bereits erwähnte PCT/CH 2006/000695 verwiesen.FIG. 1 shows an actuator 1 which has a housing 2 which has an upper housing part 2a and a second housing part 2b and in which an electric motor 4 is mounted. The power supply of the electric motor 4 takes place, for example, via a battery, not shown here, which is electrically connected via contacts 5 to the electric motor 4. In the housing 2, a pusher member 3 is also mounted, which has a rear part 3a and a front part 3b, which engage with mounted actuator 1 in the key channel of an electromechanical rotary lock cylinder, not shown here. With this presser member 3, two locking pins 6 can be biased by inserting a key, not shown here in the keyway. With a locking lever 9, the two locking pins 6 can be locked according to Figure 3, so that they remain during pretensioning in the original position. For the disclosure of the basic structure of such an actuator and an electromechanical rotary lock cylinder reference is made to the already mentioned PCT / CH 2006/000695.
Der Aktuator 1 besitzt eine elektronische Schaltung E, die gemäss der Figur 1 eine erste Leiterplatte 13 und eine zweite Leiterplatte 14 besitzt. Über der ersten Leiterplatte 13 sind zwei Kontaktzungen 15 angeordnet, die mit der ersten Leiterplatte 13 einen Weckschalter A bilden. Die Kontaktzungen 15 sind wie ersichtlich zuerst nach unten und dann nach oben gebogen und bilden schliesslich eine Kontaktfläche 15a die am oberen Ende des vorderen Teils 3b angeordnet ist. Wird das Drückerorgan 3 durch Einsetzen eines Schlüsselschaftes in den Schlüsselkanal nach unten bewegt, so bewegen sich auch die beiden Kontaktzungen 15 nach unten und schliessen den Weckschalter A. Dadurch wird die elektronische Schaltung E aufgeweckt und nach einer Überprüfung des Schlüsselcodes der Motor 4 eingeschaltet. Dieser dreht ein in Figur 3 lediglich angedeutetes Schneckenrad 21, das mit der Achse des Motors 4 verbunden und mit einem Zahnsegment 18 in Eingriff ist sowie mit Zahnungen 19. Das Zahnsegment 18 schwenkbar ist mit Achszapfen 20 begrenzt verschwenkbar im Gehäuse 2 gelagert und über dem Sperrhebel 9 angeordnet, der ebenfalls über Achszapfen Il begrenzt in Ausnehmungen 12 (Fig. 1) des Gehäuses 2 gelagert ist. Das Zahnsegment 18 besitzt eine erste und eine zweite Position. In der ersten Position sperrt das Zahnsegment 18 den Sperrhebel 9 in der in Figur 3 gezeigten Position. In der anderen Position, die eine andere Schwenkposition ist, ist der Sperrhebel 9 frei und kann um die Achszapfen 11 in die in Figur 4 gezeigte Stellung verschwenkt werden.The actuator 1 has an electronic circuit E, which according to FIG. 1 has a first printed circuit board 13 and a second printed circuit board 14. About the first circuit board 13 two contact tongues 15 are arranged, which form a wake-up switch A with the first circuit board 13. The contact tongues 15 are, as shown, first bent downwards and then upwards and finally form a contact surface 15a which is arranged at the upper end of the front part 3b. If the trigger member 3 is moved downwards by insertion of a key shank into the key channel, then the two contact tongues 15 also move downwards and close the wake-up switch A. As a result, the electronic key is moved Circuit E woken up and turned on after a review of the key code of the motor 4. This rotates in Figure 3 only indicated worm wheel 21, which is connected to the axis of the motor 4 and with a toothed segment 18 is engaged and with serrations 19. The sector gear 18 is pivotally mounted with journals 20 pivotally mounted in the housing 2 and above the locking lever 9, which is also limited by journals II limited in recesses 12 (Fig. 1) of the housing 2 is mounted. The sector gear 18 has a first and a second position. In the first position, the sector gear 18 locks the locking lever 9 in the position shown in Figure 3. In the other position, which is a different pivot position, the locking lever 9 is free and can be pivoted about the journal 11 in the position shown in Figure 4.
Der Sperrhebel 9 besitzt im Abstand zu den Achszapfen 11 jeweils eine Ausnehmung 10, in die jeweils gemäss Figur 3 ein Fuss 8 eines Sperrelementes 6 eingreift. Ist der Sperrhebel 9 gemäss Figur 3 durch das Zahnsegment 18 gesperrt, so können die beiden Sperrstifte 6 nicht nach unten bewegt werden. Durch Niederdrücken des Drückerorgans 3 können somit die beiden Sperrstifte 6 vorgespannt werden. Die vorgesehenen Federn sind hier nicht gezeigt. Ist der Sperrhebel 9 hingegen frei, so können die beiden Sperrstifte 6 in Folge der genannten Vorspannung in die in Figur 4 gezeigte untere Stellung bewegt werden. Die Sperrstifte 6 sind hierbei in einem Führungsteil 7 (Fig. 4) verschieblich geführt. In dieser Stellung ragen die Sperrstifte 6 nicht mehr in den Rotor des Drehschliesszylinders und geben diesen somit frei. Der Sperrhebel 9 wird in der in Figur 4 gezeigten Schwenkposition durch die nach unten bewegten Sperrstifte 6 durch den Anschlag der Füsse 8 an jeweils einem Ansatz 22 gesperrt. Der Sperrhebel 9 kann somit erst dann in die in Figur 3 gezeigte Ausgangsstellung verschwenkt werden, wenn der Schlüssel abgezogen und das Drückerorgan 3 sowie die beiden Sperrstifte 6 durch eine hier nicht gezeigte Feder wieder nach oben in die in Figur 3 gezeigte Stellung bewegt werden. Hat der Sperrhebel 9 die in Figur 3 gezeigte Stellung erreicht, so wird er durch eine entsprechende Schwenkbewegung des Zahnsegmentes 18 wieder gesperrt. Die beiden Sperrstifte 6 können dann somit nicht mehr nach unten bewegt werden.The locking lever 9 has at a distance from the journal 11 each have a recess 10, in each of which according to Figure 3, a foot 8 of a locking element 6 engages. If the locking lever 9 is locked according to Figure 3 by the toothed segment 18, the two locking pins 6 can not be moved down. By depressing the trigger member 3 thus the two locking pins 6 can be biased. The provided springs are not shown here. If the locking lever 9, however, free, so the two locking pins 6 can be moved in consequence of said bias in the lower position shown in Figure 4. The locking pins 6 are guided displaceably in a guide part 7 (FIG. 4). In this position, the locking pins 6 no longer protrude into the rotor of the rotary lock cylinder and thus release it. The locking lever 9 is locked in the pivot position shown in Figure 4 by the downwardly moved locking pins 6 by the stop of the feet 8 at one approach 22. The locking lever 9 can thus be pivoted only in the starting position shown in Figure 3 when the key is removed and the trigger member 3 and the two locking pins 6 are moved by a spring, not shown here back up into the position shown in Figure 3. If the locking lever 9 has reached the position shown in FIG. 3, it is again locked by a corresponding pivot movement of the toothed segment 18. The two locking pins 6 can then no longer be moved down.
Damit der Motor 4 das Zahnsegment 18 erst dann verschwenkt, wenn der Sperrhebel 9 sich in der in Figur 3 gezeigten Stellung befindet, ist ein Haltekontakt B vorgesehen, der ein Kontaktelement 16 aufweist, das eine erste Zunge 16a und eine längere zweite Zunge 16b besitzt. Diese Zungen 16a und 16b sind gemäss der Figur 5 an einem Steg 16c angebracht, mit dem das Kontaktelement 16 an einem Steg 23 des Sperrhebels 9 befestigt ist, wie die Figur 2 zeigt. Das Kontaktelement 16 ist insbesondere mit dem Steg 16c auf den Sperrhebel 9 aufgerastet. Beim Verschwenken des Sperrhebels 9 schleifen die beiden Zungen 16a und 16b an einem ersten Kontakt 17a bzw. an einem zweiten Kontakt 17b der Leiterplatte 14. In der Stellung des Sperrhebels 9 gemäss Figur 4 verbindet das Kontaktelement 16 die beiden Kontakte 17a und 17b miteinander. Durch diese elektrische Überbrückung der beiden Kontakte wird über die elektronische Schaltung E der Motor 4 in der Ruhestellung gehalten. Auch beim Aufwecken der elektronischen Schaltung E kann der Motor 4 deshalb nicht eingeschaltet werden. Befindet sich das Kontaktelement 16 jedoch in der in Figur 2 gezeigten unteren Position, so ist lediglich noch die erste Zunge 16a mit dem ersten Kontakt 17a in Kontakt. Der Kontakt zwischen der zweiten Zunge 16b und dem zweiten Kontakt ITb ist hingegen aufgehoben. In dieser Schaltposition kann der Motor 4 von der elektronischen Schaltung E geschaltet werden. Vor dem Erreichen dieser Position jedoch nicht. Der Haltekontakt B stellt damit sicher, dass das Zahnsegment 18 durch den Motor 4 erst dann in die Sperrposition verschwenkt wird, wenn der Sperrhebel 9 nach dem Abziehen des Schlüssels die in Figur 3 gezeigte Stellung erreicht hat. Der Haltekontakt B bzw. Halteschalter ist hier durch elektrische Kontakte realisiert. Grundsätzlich könnte der Haltekontakt B aber auch beispielsweise mittels Sensoren beispielsweise mit einem Hallsensor realisiert werden.Thus, the motor 4, the sector gear 18 is only pivoted when the locking lever 9 is in the position shown in Figure 3, a holding contact B is provided which has a contact element 16 which has a first tongue 16a and a longer second tongue 16b. These tongues 16a and 16b are attached according to FIG. 5 to a web 16c, with which the contact element 16 is attached to a web 23 of the locking lever 9, as Figure 2 shows. The contact element 16 is latched in particular with the web 16c on the locking lever 9. When the locking lever 9 is pivoted, the two tongues 16a and 16b grind at a first contact 17a and at a second contact 17b of the printed circuit board 14. In the position of the locking lever 9 according to FIG. 4, the contact element 16 connects the two contacts 17a and 17b with one another. By this electrical bridging of the two contacts is held on the electronic circuit E of the motor 4 in the rest position. Even when waking up the electronic circuit E, the motor 4 can therefore not be turned on. However, if the contact element 16 is in the lower position shown in FIG. 2, only the first tongue 16a is in contact with the first contact 17a. The contact between the second tongue 16b and the second contact ITb is, however, canceled. In this switching position, the motor 4 can be switched by the electronic circuit E. However, not before reaching this position. The holding contact B thus ensures that the toothed segment 18 is pivoted by the motor 4 only in the locked position when the locking lever 9 has reached the position shown in Figure 3 after removal of the key. The holding contact B or holding switch is realized here by electrical contacts. In principle, however, the holding contact B could also be realized, for example, by means of sensors, for example with a Hall sensor.
Der erfindungsgemässe Aktuator 1 kann aus wenigen und robusten Teilen und mit einer weitgehend starren und formschlüssigen Kraftübertragung hergestellt werden. Eine Öffnung durch Vibration kann dadurch vermieden werden. Da durch den genannten Haltekontakt sichergestellt ist, dass nach dem Abziehen des Schlüssels im vorgesehenen Zeitpunkt die Sperrstifte 6 wieder verriegelt werden, ergibt sich zudem eine hohe Funktionssicherheit. The inventive actuator 1 can be made of a few and robust parts and with a largely rigid and positive power transmission. An opening by vibration can be avoided. Since it is ensured by said holding contact that after removing the key in the intended time, the locking pins 6 are locked again, also results in a high reliability.
