Description

Die Erfindung betrifft eine Schließeinrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a locking device having the features of the preamble of patent claim 1.

Aus der DE 44 38 168 A1 ist eine Schließeinrichtung bekannt, welche Sensoren aufweist, die auf durch Aufbohren eines Beschlags der Schließeinrichtung verursachte Vibrationen ansprechen. Der Aktor ist in Form einer Sirene ausgebildet, welche bei einem Ansprechen der Sensoren einen Alarmton auslöst.From the DE 44 38 168 A1 For example, a locking device is known which has sensors that respond to vibrations caused by drilling a fitting of the locking device. The actuator is designed in the form of a siren, which triggers an alarm sound when the sensors respond.

Eine weitere Möglichkeit der Manipulation einer Schließeinrichtung ist das sogenannte "Picking". Hierbei wird versucht, die Sperrstifte eines Schließzylinders durch mechanisches Einwirken oder durch Beaufschlagung mit Schwingungen aus ihren jeweiligen Sperrstellungen in ihre jeweiligen Freigabestellungen zu überführen.Another possibility of manipulating a locking device is the so-called "picking". This attempts to convert the locking pins of a lock cylinder by mechanical action or by applying vibrations from their respective blocking positions in their respective release positions.

Aus der DE 203 08 579 A1 ist ein Profilzylinder bekannt, mit einer Ziehschutzscheibe, welche mittels eines Ankers eines Hubmagneten verriegelbar ist.From the DE 203 08 579 A1 is a profile cylinder known, with a pull-off, which can be locked by means of an armature of a solenoid.

Aus der EP 0 860 567 A1 ist eine Schließvorrichtung mit einem Zylinderkern bekannt, der durch Sperrstifte und ein Zusatzsperrelement verriegelbar ist.From the EP 0 860 567 A1 a locking device with a cylinder core is known, which is lockable by locking pins and an additional locking element.

Aus der US 4,114,412 A ist ein Schließzylinder mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 bekannt. Bei diesem Schließzylinder bewirkt eine axiale Verschiebung eines Sperrstifts eine Verschiebung eines Rings mit einer Steuerfläche, wodurch ein Mikroschalter betätigt und ein Timer aktiviert wird. Wenn nach Ablauf einer im Timer hinterlegten Zeitspanne der Zylinderkern nicht gedreht wurde, wird ein Alarmsignal ausgelöst und ein Zusatzsperrelement zum Sperren des Zylinderkerns in eine Sperrlage verbracht.From the US 4,114,412 A a lock cylinder with the features of the preamble of claim 1 is known. In this lock cylinder, an axial displacement of a locking pin causes a displacement of a ring with a control surface, whereby a micro-switch is actuated and a timer is activated. If, after the expiration of a period of time stored in the timer, the cylinder core has not been turned, an alarm signal is triggered and on Additional locking element spent to lock the cylinder core in a locked position.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Schließeinrichtung der eingangs genannten Art so zu verbessern, dass eine Manipulation der Schließeinrichtung bestmöglich verhindert werden kann.On this basis, the present invention has the object to improve a locking device of the type mentioned so that a manipulation of the locking device can be prevented as best as possible.

Diese Aufgabe wird bei einer Schließeinrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Dies ermöglicht ein mechanisches Versperren des Schließzylinders für den Fall, dass ein Manipulationsversuch erkannt wurde. Im Unterschied zum aus der DE 44 38 168 A1 bekannten Stand der Technik wird also nicht nur ein Manipulationsversuch erschwert (durch Auslösen eines Alarmtons), sondern es wird mittels der mechatronischen Zusatzsperre ein Entsperren des Schließzylinders verhindert. Es ist dabei unerheblich, ob es einer unbefugten Person gelingt, die Sperrstifte des Schließzylinders so zu manipulieren, dass ein Zylinderkern relativ zu einem Zylindergehäuse des Schließzylinders verdreht werden könnte. Das Verdrehen des Zylinders kann nämlich mittels der mechatronischen Zusatzsperre verhindert werden, und zwar unabhängig von einer Freigabeposition der Sperrstifte.This object is achieved with a locking device having the features of the preamble of claim 1 according to the invention with the characterizing features of claim 1. This allows a mechanical locking of the lock cylinder in the event that a tampering attempt has been detected. In contrast to from the DE 44 38 168 A1 known prior art, therefore, not only a manipulation attempt is difficult (by triggering an alarm sound), but it is prevented by means of the mechatronic additional lock unlocking the lock cylinder. It is irrelevant whether an unauthorized person manages to manipulate the locking pins of the lock cylinder so that a cylinder core could be rotated relative to a cylinder housing of the lock cylinder. The twisting of the cylinder can namely be prevented by means of the mechatronic additional lock, regardless of a release position of the locking pins.

Die mechatronische Zusatzsperre umfasst vorzugsweise einen elektronischen Aktor (bspw. einen Elektromotor) und ein von dem elektronischen Aktor angetriebenes mechanisches Zusatzsperrelement (bspw. in Form eines Zusatzsperrstifts). In einer Freigabestellung behindert das Zusatzsperrelement eine Drehbewegung des Zylinderkerns in dem Zylindergehäuse nicht. In einer Sperrstellung des Zusatzsperrelements verriegelt dieses den Zylinderkern in dem Zylindergehäuse und verhindert eine Drehbewegung des Zylinderkerns.The mechatronic additional lock preferably comprises an electronic actuator (for example an electric motor) and a mechanical additional locking element driven by the electronic actuator (for example in the form of an additional locking pin). In a release position, the additional locking element does not hinder rotational movement of the cylinder core in the cylinder housing. In a blocking position of Zusatzsperrelements this locks the cylinder core in the cylinder housing and prevents rotation of the cylinder core.

Bei einer bevorzugten Ausführungsform ist vorgesehen, dass die Ansteuereinrichtung in einem Hauptbetriebszustand in einem Ruhezustand gehalten ist und dass eine Aufweckeinrichtung vorgesehen ist, welche infolge einer durch Manipulationsversuche verursachten Bewegung zumindest eines Teils der Schließeinrichtung die Ansteuereinrichtung in einen aktiven Betriebszustand versetzt. Eine solche Aufweckeinrichtung reagiert auf Bewegungen von Teilen der Schließeinrichtungen und versetzt die Ansteuereinrichtung aus einem passiven Ruhezustand in einen aktiven Betriebszustand. In dem Ruhezustand ist der Energiebedarf der Ansteuereinrichtung reduziert. Üblicherweise ist eine Schließeinrichtung sehr langen Zeiträumen keinem Manipulationsversuch ausgesetzt, sodass bei Verwendung einer vorstehend genannten Aufweckeinrichtung in dieser Zeit keine unnötige Energie verbraucht wird. Kommt es zu einem Manipulationsversuch, versetzt die Aufweckeinrichtung die Ansteuereinrichtung in einen aktiven Betriebszustand. Erst in diesem aktiven Betriebszustand ist der Energiebedarf der Schließeinrichtung erhöht.In a preferred embodiment it is provided that the drive device is held in a main operating state in an idle state and that a wake-up device is provided, which causes the drive device in an active operating state as a result of manipulation caused by movement of at least a portion of the closing device. Such a wake-up device responds to movements of parts of the closing devices and puts the driving device from a passive rest state into an active operating state. In the idle state, the energy requirement of the drive device is reduced. Usually, a locking device is exposed to very long periods of no manipulation attempt, so that when using a waking device mentioned above in this time no unnecessary energy is consumed. If a manipulation attempt occurs, the wake-up device puts the activation device in an active operating state. Only in this active operating state, the energy consumption of the locking device is increased.

Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Aufweckeinrichtung einen lageempfindlichen Sensor umfasst, welcher ein durch Erschütterung und/oder Vibration zumindest eines Teils der Schließeinrichtung bewegbares Kontaktierungselement zur Herstellung und/oder Unterbrechung eines elektrischen Kontakts umfasst. Ein solcher lageempfindlicher Sensor ist beispielsweise unter der Bezeichnung "SPSF" oder "SPSG" der Firma ALPS, Tokio, Japan, bekannt. Sensoren dieser Art werden üblicherweise zur Detektierung der Neigungslage einer Kamera, beispielsweise in einem Mobiltelefon, eingesetzt. Erfindungsgemäß kann ein solcher lageempfindlicher Sensor in einer Schließeinrichtung verwendet werden, wobei die Lage des Sensorgehäuses auch bei Ausübung von Vibrationen auf die Schließeinheit im Wesentlichen dieselbe bleibt. Jedoch sind die bei einem Manipulationsversuch auftretenden Erschütterungen und/oder Vibrationen ausreichend, um das Kontaktierungselement des Sensors (beispielsweise eine Goldkugel) zumindest kurzzeitig aus einer gravitationsbedingten Ruhelage in eine ausgelenkte Lage zu verbringen, in welcher andere Kontakte des Sensors kontaktiert werden als in der Ruhelage.In a preferred embodiment of the invention it is provided that the wake-up device comprises a position-sensitive sensor which comprises a contact element which is movable by vibration and / or vibration of at least part of the closure device for producing and / or interrupting an electrical contact. Such a position-sensitive sensor is known, for example, under the name "SPSF" or "SPSG" from ALPS, Tokyo, Japan. Sensors of this type are usually used to detect the tilt of a camera, for example in a mobile phone. According to the invention, such a position-sensitive sensor in a locking device be used, wherein the position of the sensor housing remains substantially the same even when exerting vibrations on the clamping unit. However, the vibrations and / or vibrations occurring in a manipulation attempt are sufficient to spend the contacting element of the sensor (for example a gold ball) at least temporarily from a gravitational rest position into a deflected position in which other contacts of the sensor are contacted than in the rest position.

Es ist möglich, dass der lageempfindliche Sensor von dem Bewegungssensor separat bereitgestellt ist. Bei einer besonders bevorzugten Ausführungsform ist es jedoch vorgesehen, dass der Bewegungssensor in Form des lageempfindlichen Sensors ausgebildet ist. Dies bedeutet, dass der lageempfindliche Sensor sowohl für die Aufweckfunktion als auch für die Bereitstellung von Daten bereitgestellt ist, welche Anhaltspunkte dahingehend enthalten, ob es sich bei der erfassten Erschütterung und/oder Vibration um einen sogenannten "Picking"-Versuch handelt.It is possible that the position-sensitive sensor is provided separately from the motion sensor. In a particularly preferred embodiment, however, it is provided that the movement sensor is designed in the form of the position-sensitive sensor. This means that the position-sensitive sensor is provided both for the wake-up function and for the provision of data which contain indications as to whether the detected vibration and / or vibration is a so-called "picking" attempt.

Erfindungsgemäß umfasst die Schließeinrichtung eine Auswerteeinrichtung zur Auswertung von mittels einer Filtereinrichtung gefilterten Signalen des Bewegungssensors. Die Auswerteeinrichtung ist vorzugsweise in einem Hauptbetriebszustand in einem Ruhestand gehalten und mittels der Aufweckeinrichtung in einen aktiven Betriebszustand versetzbar.According to the invention, the closing device comprises an evaluation device for evaluating signals of the motion sensor filtered by means of a filter device. The evaluation device is preferably kept in a main operating state in a retirement and set by means of the wake-up device in an active operating state.

Bevorzugt ist es, dass die Auswerteeinrichtung und die Ansteuereinrichtung zu einem Mikrocontroller zusammengefasst sind, wodurch eine kompakte Schließeinrichtung bereitstellbar ist.It is preferred that the evaluation device and the control device to a microcontroller are summarized, whereby a compact locking device can be provided.

Die erfindungsgemäße Schließeinrichtung ist besonders gut für einen Batteriebetrieb geeignet, wobei in Folge des über einen langen Zeitraum reduzierten Energiebedarf auch Knopfzellen zum Einsatz kommen können. Solche Batterien, insbesondere Knopfzellen, müssen dann nur in sehr langen Zeitabständen (beispielsweise alle 5 bis 10 Jahre) ausgetauscht werden.The locking device according to the invention is particularly well suited for battery operation, with button cells also being able to be used as a consequence of the reduced energy requirement over a long period of time. Such batteries, especially button cells, then need to be replaced only at very long intervals (for example every 5 to 10 years).

Eine weitere Verbesserung der Sicherheit der Schließeinrichtung kann dadurch erzielt werden, dass elektronische Bauteil der Schließeinrichtung, insbesondere die Ansteuereinrichtung bzw. Teile davon und/oder die Aufweckeinrichtung bzw. Teile davon und/oder eine Auswerteeinrichtung zur Auswertung von Signalen eines Bewegungssensors und/oder eine Batterie, auf einer Schlossinnenseite der Schließeinrichtung angeordnet und somit gegen einen Zugriff von außen gesichert sind.A further improvement in the safety of the locking device can be achieved by electronic components of the locking device, in particular the control device or parts thereof and / or the wake-up device or parts thereof and / or an evaluation device for evaluating signals of a motion sensor and / or a battery , Arranged on a lock inside the locking device and thus secured against access from the outside.

Schließlich ist es bevorzugt, wenn die mechatronische Zusatzsperre bzw. Teile davon) auf einer Schlossaußenseite der Schließeinrichtung angeordnet sind. Auf diese Weise steht auf der Schlossinnenseite mehr Platz zur Anordnung elektronischer Bauteile zur Verfügung.Finally, it is preferred if the additional mechatronic lock or parts thereof) are arranged on a lock outer side of the closing device. In this way, more space is available on the inside of the lock for arranging electronic components.

Weitere Merkmale und Vorteile der Erfindung sind Gegenstand der nachfolgenden Beschreibung und der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels.Further features and advantages of the invention are the subject of the following description and the diagrammatic representation of a preferred embodiment.

In the drawing shows:
Fig. 1
a side view of an embodiment of a locking device.

Eine Ausführungsform einer Schließeinrichtung ist in Figur 1 insgesamt mit dem Bezugszeichen 10 bezeichnet. Die Schließeinrichtung 10 umfasst einen Schließzylinder mit einem Zylindergehäuse 12 und mit einem Zylinderkern 14 zur Anordnung auf einer Schlossaußenseite und mit einem Zylinderkern 16 zur Anordnung auf einer Schlossinnenseite.An embodiment of a locking device is in FIG. 1 generally designated by the reference numeral 10. The locking device 10 comprises a lock cylinder with a cylinder housing 12 and with a cylinder core 14 for arrangement on a lock outer side and with a cylinder core 16 for arrangement on a lock inside.

Die Zylinderkerne 14 und 16 wirken mit einem mechanischen Schlüssel 18 zusammen, der beim Einführen in die Zylinderkerne 14, 16 mechanische Sperrstifte 20 aus einer Verriegelungsposition (in Figur 1 beispielhaft für die Zylinderkerne 14 und 16 dargestellt) in eine Entriegelungsposition verbringt.The cylinder cores 14 and 16 cooperate with a mechanical key 18 which, when inserted into the cylinder cores 14, 16 mechanical locking pins 20 from a locking position (in FIG. 1 exemplified for the cylinder cores 14 and 16) in an unlocking position spends.

Die Schließeinrichtung 10 umfasst ferner einen Schließbart 22 und ein Gewindeloch 24.The closure device 10 further comprises a lock bit 22 and a threaded hole 24.

Die Schließeinrichtung umfasst eine Energieversorgungseinrichtung 26, welche insbesondere in Form einer Knopfzelle 28 ausgebildet ist.The closing device comprises a power supply device 26, which is designed in particular in the form of a button cell 28.

Die Knopfzelle 28 dient zur Energieversorgung eines Mikrocontrollers 30, welcher eine Auswerteeinrichtung 32 und eine Ansteuereinrichtung 34 umfasst. Die Auswerteeinrichtung 32 kommuniziert mit einer Filtereinrichtung 36 zur Filterung von Signalen eines Bewegungssensors 38, welcher vorzugsweise in Form eines lageempfindlichen Sensors 40 ausgebildet ist.The button cell 28 serves to supply power to a microcontroller 30, which comprises an evaluation device 32 and a drive device 34. The evaluation device 32 communicates with a filter device 36 for filtering signals of a motion sensor 38, which is preferably designed in the form of a position-sensitive sensor 40.

Die Ansteuereinrichtung 34 kommuniziert mit einem elektronischen Aktor 42 in Form eines Elektromotors 44. Der Elektromotor 44 treibt über eine Kraft- und/oder Bewegungsübertragungseinrichtung 46 ein insbesondere stiftförmiges Zusatzsperrelement 48 an. Das Zusatzsperrelement 48 kann aus einem in Figur 1 dargestellten Freigabezustand, in welcher in einem Freigabezustand der Sperrstifte 20 eine Drehung des Zylinderkerns 14 in dem Zylindergehäuse 12 möglich ist, in einen Verriegelungszustand verfahren werden, in welchem das Zusatzsperrelement 48 mit einer Sperrelementaufnahme 50 des Zylinderkerns 14 in Eingriff gebracht ist, und in welchem eine Drehung des Zylinderkerns 14 in dem Zylindergehäuse 12 unabhängig von dem Zustand der Sperrstifte 20 blockiert ist.The control device 34 communicates with an electronic actuator 42 in the form of an electric motor 44. The electric motor 44 drives a particular pin-shaped additional locking element 48 via a force and / or motion transmission device 46. The additional locking element 48 may consist of a in FIG. 1 shown release state in which in a release state of the locking pins 20, a rotation of the cylinder core 14 in the cylinder housing 12 is possible to be moved in a locking state in which the additional locking element 48 is brought into engagement with a locking element receptacle 50 of the cylinder core 14, and in which Rotation of the cylinder core 14 in the cylinder housing 12 is blocked regardless of the state of the locking pins 20.

Der Elektromotor 44, die Kraft- und/oder Bewegungsübertragungseinrichtung 46, das Zusatzsperrelement 48 und die Sperrelementaufnahme 50 bilden gemeinsam eine mechatronische Zusatzsperre 52.The electric motor 44, the force and / or movement transmission device 46, the additional locking element 48 and the blocking element receptacle 50 together form a mechatronic additional lock 52.

Der lageempfindliche Sensor 40 und die Filtereinrichtung 36 sind Teil einer Aufweckeinrichtung 54.The position-sensitive sensor 40 and the filter device 36 are part of a wake-up device 54.

Die Schließeinrichtung 10 funktioniert wie folgt:
In einem nicht manipulierten Zustand sind die Ansteuereinrichtung 34 und die Auswerteeinrichtung 32 in einem Ruhezustand gehalten. In diesem Zustand kontaktiert ein Kontaktelement des lageempfindlichen Sensors 40 gravitationsbedingt zwei erste elektrische Kontakte. Kommt es zu einem Manipulationsversuch und wird die Schließeinrichtung 10 einer Erschütterung und/oder Vibrationen ausgesetzt, wird auch das Kontaktierungselement des lageempfindlichen Sensors 40 in Bewegung versetzt, sodass die zuvor beschriebene Kontaktierung unterbrochen und/oder ein Kontakt zwischen anderen Kontaktelementen des Sensors 40 hergestellt wird. Diese Zustandsänderung des Sensors 40 erzeugt ein Signal, das die Filtereinrichtung 36 filtert und an den Mikrocontroller 30 weitergibt. Hierdurch wird der Mikrocontroller 30 in einen aktiven Betriebszustand versetzt, in welchem die Auswerteeinrichtung 32 mittels des Sensors 40 erzeugte und mittels der Filtereinrichtung 36 gefilterte Signale auswertet. Wenn die Auswerteeinrichtung 32 einen mit einem "Pickingversuch" korrespondierenden Signalverlauf erkennt, wird ein entsprechendes Steuersignal erzeugt, wodurch die Ansteuereinrichtung 34 den Elektromotor 44 aktiviert, sodass dieser das Zusatzsperrelement 48 aus seinem Freigabezustand in seinen Verriegelungszustand überführt, in welchem das Zusatzsperrelement 48 in die Sperrelementaufnahme 50 eingefahren ist.The locking device 10 works as follows:
In a non-manipulated state, the control device 34 and the evaluation device 32 are held in an idle state. In this state, a contact element of the position-sensitive sensor 40 gravitationally contacted two first electrical contacts. If a tampering attempt occurs and the locking device 10 is subjected to vibration and / or vibration, the contacting element of the position-sensitive sensor 40 is also set in motion, so that the contacting described above is interrupted and / or a contact between other contact elements of the sensor 40 is made. This change of state of the sensor 40 generates a signal that filters the filter device 36 and passes it on to the microcontroller 30. As a result, the microcontroller 30 is put into an active operating state, in which the evaluation device 32 evaluates signals generated by the sensor 40 and filtered by the filter device 36. If the evaluation device 32 detects a signal course corresponding to a "picking attempt", a corresponding control signal is generated, whereby the activation device 34 activates the electric motor 44 so that it transfers the additional blocking element 48 from its release state into its locking state, in which the additional blocking element 48 enters the blocking element receptacle 50 retracted.

Sofern die Auswerteeinrichtung 32 während einer vorgebbaren Zeitdauer keine Erschütterungen und/oder Vibrationen mehr erfasst, kann ein Freigabesignal an die Ansteuereinrichtung 34 erzeugt werden, welches wiederum den Elektromotor 44 ansteuert, sodass dieser das Zusatzsperrelement 48 wieder in den aus der Sperrelementaufnahme 50 ausgefahrenen Freigabezustand überführt. Abschließend wird der Mikrocontroller 30 wieder in den Ruhezustand versetzt.If the evaluation device 32 no longer detects vibrations and / or vibrations during a predefinable time period, a release signal can be generated at the control device 34, which in turn drives the electric motor 44 so that it transfers the additional locking element 48 back into the release state extended from the blocking element receptacle 50. Finally, the microcontroller 30 is returned to the idle state.
