Description

Die Erfindung betrifft einen Sperrmechanismus, insbesondere für einen Schließzylinder zum wahlweisen Blockieren oder Freigeben eines in einem Gehäuse angeordneten beweglichen Kerns, mit einem in den Bewegungsbereich des Kerns geführten Sperrriegel, mit einer zur Vorspannung des Sperrriegels in die den Kern blockierende Richtung vorgesehenen Sperrfeder, mit einem Aktor zur Halterung des Sperrriegels, wobei die Bewegungsrichtungen des Sperrriegels und des Aktors im Wesentlichen quer zueinander verlaufen, und mit einer Steuerelektronik zur Ansteuerung des Aktors.The invention relates to a locking mechanism, in particular for a locking cylinder for optional blocking or releasing a movable one arranged in a housing Core, with one in the range of motion of the core guided locking bolt, with a for preloading the Locking bolt provided in the direction blocking the core Locking spring, with an actuator for holding the Locking bolt, the directions of movement of the locking bolt and the actuator are essentially transverse to each other, and with control electronics for control of the actuator.

Ein solcher Sperrmechanismus ist beispielsweise aus der DE 32 08 818 C2 bekannt. Hierbei ist der Sperrriegel stiftförmig gestaltet und ragt in schräg zur Mantelfläche auslaufende Kalotten des Kerns hinein. Eine Lagerachse des Aktors und der Sperrriegel sind parallel angeordnet, so dass bei einer Ansteuerung des piezoelektrischen Elements der Aktor in eine Sperrausnehmung des Sperrriegels eingedrückt wird. Eine Rückholfeder zieht den Aktor wieder aus der Ausnehmung heraus. Zum Blockieren der Bewegung des Kerns muss das piezoelektrische Element permanent angesteuert werden, um den Aktor in der Sperrausnehmung des Sperrriegels zu halten. Bei einer vorgesehenen Freigabe des Sperrmechanismus unterbleibt die Ansteuerung, so dass der Aktor von der Rückholfeder aus der Sperrausnehmung des Sperrriegels herausbewegt wird. In einer alternativen Ausführungsform ist das piezoelektrische Element der Sperrfeder gegenüberstehend angeordnet und bewegt damit eine bauliche Einheit aus Aktor und Sperrriegel gegen die Kraft der Sperrfeder.Such a locking mechanism is for example from the DE 32 08 818 C2 known. Here is the locking bolt designed like a pin and protrudes at an angle to the outer surface leaking domes of the core. A bearing axis of the actuator and the locking bolt are arranged in parallel, so that when the piezoelectric element is activated the actuator into a locking recess in the locking bolt is pushed in. A return spring pulls the actuator again out of the recess. To block the movement the core, the piezoelectric element must be permanent can be controlled to the actuator in the locking recess to hold the locking bolt. With a provided Activation of the locking mechanism is not activated, so that the actuator from the return spring from the Lock recess of the locking bolt is moved out. In an alternative embodiment is the piezoelectric Element of the locking spring arranged opposite and thus moves a structural unit consisting of actuator and Locking bolt against the force of the locking spring.

Nachteilig bei dem bekannten Sperrmechanismus ist, dass der Aktor entweder der Sperrfeder oder einer eigenen Rückholfeder gegenüberstehend angeordnet ist, so dass bei einer Freigabe der Bewegung des Kerns der Aktor gegen die Kraft zumindest einer Feder bewegt werden muss. Dies führt zu einem hohen Energieverbrauch des Sperrmechanismus. Weiterhin erfordert die ständige Bereitschaft der Steuerelektronik und eine ständige Ansteuerung des piezoelektrischen Elements einen sehr hohen Energieverbrauch. Da solche Sperrmechanismen häufig in Eingangstüren von Gewerbe- oder Wohnräumen eingesetzt werden und eine längere Zeitspanne ohne Stromzufuhr funktionstüchtig sein sollen, ist ein hoher Energieverbrauch jedoch sehr störend.A disadvantage of the known locking mechanism is that the actuator either the locking spring or its own Return spring is arranged opposite, so that at a release of the movement of the core of the actuator against the Force must be moved at least one spring. This leads to high energy consumption of the locking mechanism. Furthermore, the constant readiness of the Control electronics and constant control of the piezoelectric Elements have a very high energy consumption. Since such locking mechanisms are often in the entrance doors of Commercial or residential spaces are used and a longer one Be functional for a period of time without power high energy consumption is very annoying.

Weiterhin ist aus der DE 196 17 151 A1 eine Zuhalteeinrichtung bekannt, bei der ein Schließblech oder ein Riegel den Aktor aufweist. Der Aktor kann beispielsweise ein piezoelektrisches Element, einen magnetostriktiven Aktor oder einen Shape-Memory-Aktor aufweisen und drückt einen Hebel gegen die Kraft einer Feder gegen ein Profil. Auch bei dieser Zuhalteeinrichtung führt die Bewegung des Aktors gegen die Kraft der Feder zu einer sehr hohen Stromaufnahme.Furthermore, from DE 196 17 151 A1 a locking device known in which a striking plate or a bolt has the actuator. The actuator can be, for example piezoelectric element, a magnetostrictive actuator or have a shape memory actuator and presses one Lever against the force of a spring against a profile. Also With this locking device, the movement of the actuator leads against the force of the spring to a very high current consumption.

Der Erfindung liegt das Problem zugrunde, einen Sperrmechanismus der eingangs genannten Art so zu gestalten, dass er einen besonders geringen Energieverbrauch aufweist. The invention is based on the problem of a locking mechanism of the type mentioned at the outset, that it has a particularly low energy consumption.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Aktor zumindest bereichsweise als Piezobieger oder als magnetostriktives Element ausgebildet ist, dass der Aktor mit seinem dem Sperrriegel abgewandten Ende in dem Gehäuse befestigt ist und dass der Aktor zur Halterung des Sperrriegels durch Festklemmen in der die Bewegung des Kerns freigebenden Stellung und zur Freigabe der Bewegung des Sperriegels in die die Bewegung des Kerns blockierende Stellung ausgebildet ist.According to the invention, this problem is solved in that the actuator at least in some areas as a piezo bender or is designed as a magnetostrictive element that the Actuator with its end facing away from the locking bolt in the Housing is attached and that the actuator to the bracket the locking bolt by clamping in the the movement the core releasing position and to release the movement of the lock bolt in the the movement of the core blocking position is formed.

Durch diese Gestaltung des erfindungsgemäßen Sperrmechanismus kann sich der Aktor frei und damit ohne Behinderung einer Feder bewegen. Der Energiebedarf zur Bewegung des Aktors ist daher besonders gering. Weiterhin wird dank der Erfindung der Aktor nur dann angesteuert, wenn eine Freigabe des erfindungsgemäßen Sperrmechanismus erfolgen soll. Da der Kern in der Regel die überwiegende Zeit in der blockierten Stellung verbleiben soll, führt dies zu einer starken Verringerung des Energiebedarfs. Auf die auf dem Sperrriegel angeordnete Sperrausnehmung lässt sich verzichten, da der Sperrriegel durch Klemmkräfte gehalten wird. Hierdurch wird der Weg, den der Aktor zwischen der die Bewegung des Kerns sperrenden Stellung und der die Bewegung des Kerns freigebenden Stellung zurücklegen muss, besonders klein gehalten. Dies führt zu einer weiteren Verringerung des Energiebedarfs des Aktors. Die Einklemmung des Sperrriegels durch den Aktor in die die Bewegung des Kerns freigebende Stellung führt zudem zu sehr geringen Haltekräften des Sperrriegels. Vorzugsweise wird der Sperrriegel zwischen einem einzigen Aktor und dem Gehäuse eingeklemmt.By designing the locking mechanism according to the invention the actuator can move freely and therefore without disability moving a feather. The energy requirement for movement the actuator is therefore particularly small. Will continue thanks to the invention, the actuator is only activated when the locking mechanism according to the invention is released should. Because the core is usually the predominant one Time should remain in the blocked position this leads to a sharp reduction in energy consumption. On the locking recess arranged on the locking bolt can be dispensed with because the locking bolt is caused by clamping forces is held. This is the way the actuator between the position blocking the movement of the core and the position releasing the movement of the core must be kept particularly small. this leads to a further reduction in the energy requirement of the actuator. The locking of the locking bolt by the actuator in the position releasing the movement of the core also leads very low holding forces of the locking bolt. Preferably the locking bolt between a single Actuator and the housing clamped.

Zur weiteren Verringerung des Energiebedarfs des erfindungsgemäßen Sperrmechanismus trägt es bei, wenn der Sperrriegel beim Einführen eines Schlüssels in einen Schließkanal oder beim anfänglichen Drehen des Kerns verlagerbar ist und eine in den Bewegungsbereich des Aktors ragende Unebenheit zur Bewegung des Aktors aufweist, wenn der Aktor ein bei seiner Bewegung einen Impuls erzeugendes, vorzugsweise piezoelektrisches Element hat, und wenn die Steuerelektronik durch den durch die Bewegung des Aktors erzeugten Impuls aktivierbar ist. Durch diese Gestaltung wird ein Impuls des Elements des Aktors genutzt, um die Steuerelektronik von einem Zustand ohne oder mit sehr geringem Stromverbrauch in einen Zustand zu schalten, in dem eine Schließberechtigung des in den Schließkanal eingeführten Schlüssels erfasst wird. Der Einsatz des piezoelektrischen Elements hat den Vorteil, dass der Aktor einen besonders geringen Strombedarf hat und kostengünstig herstellbar ist.To further reduce the energy requirement of the invention Locking mechanism helps if the Locking bolt when inserting a key into one Locking channel or relocatable when the core is initially rotated is and one in the range of motion of the actuator protruding unevenness to the movement of the actuator, if the actuator generates a pulse during its movement, preferably has piezoelectric element, and if the control electronics through the movement of the actuator generated pulse can be activated. Through this design a pulse of the element of the actuator is used, to the control electronics from a state with or without switch very low power consumption into a state in which a locking authorization of the in the locking channel imported key is detected. The stake of the piezoelectric element has the advantage that the Actuator has a particularly low power requirement and is inexpensive can be produced.

Der erfindungsgemäße Sperrmechanismus erfordert einen besonders geringen Bauraum, wenn der Aktor plattenförmig gestaltet und mit seinem von dem Sperrriegel abgewandten Ende in dem Gehäuse befestigt ist und wenn ein freies Ende des Aktors gegen den Sperrriegel in seiner die Bewegung des Kerns freigebenden Stellung ausgerichtet ist. Hierdurch lässt sich der Sperrmechanismus besonders einfach in einem Profilschließzylinder anordnen.The locking mechanism according to the invention requires a special one small installation space if the actuator is plate-shaped designed and with its facing away from the locking bolt End is fixed in the housing and if a free end of the actuator against the locking bolt in its the movement of the core releasing position is aligned. This makes the locking mechanism particularly easy arrange in a profile lock cylinder.

Zur Verringerung der Anzahl der Bauteile des erfindungsgemäßen Sperrmechanismus trägt es bei, wenn das piezoelektrische Element plattenförmig gestaltet ist und im Wesentlichen den Aktor bildet.To reduce the number of components of the invention Locking mechanism helps when the piezoelectric Element is plate-shaped and in Essentially forms the actuator.

Ein Klemmen des Sperrriegels oder dessen Verhaken mit dem Aktor lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Steuerelektronik bei einer vorgesehenen Blockierung des Kerns zur umgekehrten Ansteuerung des Aktors zur Freigabe der Bewegung des Sperrriegels ausgebildet ist.A jamming of the locking bolt or its hooking with the According to another advantageous development, the actuator can be simply avoid the invention if the Control electronics in the event of a planned blocking of the Core for reverse control of the actuator for release the movement of the locking bolt is formed.

Die auf dem Sperrriegel angeordneten Unebenheiten erfordern einen besonders geringen konstruktiven Aufwand, wenn die Mantelfläche des Sperrriegels bauchig oder gewellt ist.The bumps arranged on the locking bar require a particularly low design effort, if the circumferential surface of the locking bolt is bulbous or wavy is.

Die zum Haltern des Sperrriegels erforderliche Klemmkraft lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach einstellen, wenn auf der dem Aktor gegenüberliegenden Seite des Sperrriegels ein Stellelement zur Einstellung der Position des Sperrriegels gegenüber dem Aktor angeordnet ist.The clamping force required to hold the locking bolt can be according to another advantageous development simply adjust the invention when on the Actuator opposite side of the locking bolt Control element for adjusting the position of the locking bolt is arranged opposite the actuator.

Eine zuverlässige Verriegelung oder Freigabe des erfindungsgemäßen Sperrmechanismus lässt sich einfach sicherstellen, wenn die Sperrfeder ein Stellelement zur Einstellung der Vorspannkraft des Sperrriegels hat. Vorzugsweise ist das Stellelement als in einen den Sperrriegel aufnehmenden Kanal eingedrehte Madenschraube oder eine darin eingepresste Kugel ausgebildet.A reliable locking or release of the invention Locking mechanism is easy to ensure if the locking spring is an adjusting element for adjustment the pretensioning force of the locking bolt. Preferably is the actuator as in a locking bolt receiving channel turned grub screw or a ball formed therein.

Hohe Haltekräfte des Sperrriegels bei einem besonders geringen Energiebedarf des Aktors lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erzeugen, wenn zumindest ein Reibbelag an der Mantelfläche des Sperrriegels und/oder des Aktors und/oder einer Führung des Sperrriegels vorgesehen ist. Der Reibbelag ist vorzugsweise als Beschichtung des entsprechenden Bauteils ausgebildet.High locking bolt holding forces with a particularly low one Energy requirements of the actuator can be other advantageous development of the invention simply generate if at least one friction lining on the lateral surface the locking bolt and / or the actuator and / or one Management of the locking bolt is provided. The friction lining is preferably as a coating of the corresponding component educated.

Die Montage des erfindungsgemäßen Sperrmechanismus gestaltet sich besonders einfach, wenn das Gehäuse eine in eine Stufenbohrung übergehende Tasche aufweist und wenn in der Stufenbohrung der Sperrriegel geführt und in der Tasche der Aktor angeordnet ist. Durch diese Gestaltung kann zudem der Sperrriegel durch einen Absatz der Stufenbohrung vor einem Herausfallen gesichert werden.The assembly of the locking mechanism designed according to the invention is particularly easy when the housing is in has a pocket passing pocket and if in the stepped bore of the locking bolt and in the Pocket of the actuator is arranged. Through this design can also lock the locking bolt through a shoulder of the stepped bore secured against falling out.

Der Schieber 21 weist im Bereich des Sperrriegels 13 Rampen 18 auf, welche einem als Kugel ausgebildeten Verdrängungselement 19 gegenüberstehen. In der eingezeichneten Grundstellung befindet sich der Sperrriegel 13 im Bewegungsbereich des Kerns 2 und blockiert damit dessen Bewegung. Der Aktor 11 und die Steuerelektronik 16 sind in einer Tasche 20 des Gehäuses angeordnet. Der Sperrriegel 13 ist längsverschieblich in einer Stufenbohrung 22 geführt.Figure 1 shows an unlockable from two sides Lock cylinder with a housing 1 and with one in it rotatably arranged core 2. The core 2 has in its middle area a lock bit 3 and in its ends each have a closing channel 4, 5 for inserting one key shown. The closing channels 4, 5 have a round cross-section. To transmit a rotary movement of the key on the core 2 are on the end faces of the core 2 each driver 6, 7 arranged. The Carriers 6, 7 are used to generate a positive connection with a key of the key, also not shown. The locking cylinder has an electronically activated one Locking mechanism 8, each close to the end faces of the housing 1 arranged code receivers 9, 10. The locking mechanism 8 has an actuator 11 and one of a locking spring 12 biased towards the core 2 Locking bolt 13. The actuator 11 has a plate-shaped piezoelectric element 14. The piezoelectric Element 14 is facing away from the locking bolt 13 End fixed in the housing 1 and engages with one corrugated bumps 15 provided section the locking bolt 13. A control electronics 16 receives the signals from the code receivers 9, 10 and the piezoelectric Elements 14 and controls the actuator 11. To power the control electronics 16 and the actuator 11, a battery 17 is arranged in the housing 1. In the core 2 is a slider 21 for transmitting a axial movement of one into one of the closing channels 4, 5 introduced key arranged. The slide 21 has in the area of the locking bolt 13 ramps 18 which one face as a displacement element 19. Located in the basic position shown the locking bolt 13 in the range of movement of the core 2nd and thus blocks its movement. The actuator 11 and the Control electronics 16 are in a pocket 20 of the housing arranged. The locking bolt 13 is longitudinally displaceable in a stepped bore 22 out.

Bei einem Einführen des Schlüssels in einen der Schließkanäle 4, 5 wird der Schieber 21 bewegt und drückt mit den Rampen 18 das Verdrängungselement 19 nach unten. Dabei wird der Sperrriegel 13 ebenfalls nach unten gedrückt, bis er aus dem Bewegungsbereich des Kerns 2 herausgelangt. Zur Verdeutlichung sind die Bewegungen des Schiebers 21 und des Sperrriegels 13 in der Zeichnung mit Pfeilen gekennzeichnet. Mit dem Einführen des Schlüssels in einen der Schließkanäle 4, 5 erfassen die Codeempfänger 9, 10 Signale von Transpondern des Schlüssels und leiten diese zu der Steuerelektronik 16. Die Steuerelektronik 16 ermittelt aus den Signalen des Transponders, ob der Schlüssel berechtigt ist, den Schließzylinder zu entriegeln. Bei Vorliegen einer Berechtigung steuert die Steuerelektronik 16 das piezoelektrische Element 14 des Aktors 11 an, wodurch der Aktor 11 gegen den Sperrriegel 13 gedrückt wird. Hierdurch wird der Sperrriegel 13 in seiner außerhalb des Bewegungsbereichs des Kerns 2 befindlichen Lage gehalten. Bei fehlender Berechtigung unterbleibt die Ansteuerung des piezoelektrischen Elements 14 des Aktors 11 oder dieser wird in umgekehrter Weise angesteuert, so dass sich der Aktor 11 von dem Sperrriegel 13 wegbewegt. Damit wird der Sperrriegel 13 von der Kraft der Sperrfeder 12 wieder in Richtung Kern 2 gedrückt.When the key is inserted into one of the locking channels 4, 5, the slide 21 is moved and presses with the ramps 18, the displacement element 19 down. there the locking bolt 13 is also pressed down, until it comes out of the range of movement of the core 2. The movements of the Slider 21 and the locking bolt 13 in the drawing Arrows marked. With the insertion of the key in one of the locking channels 4, 5 detect the code receiver 9, 10 signals from key and transponders route this to the control electronics 16. The control electronics 16 determines from the signals of the transponder whether the key is authorized to unlock the locking cylinder. If there is an authorization, the Control electronics 16, the piezoelectric element 14 of the Actuator 11, whereby the actuator 11 against the locking bolt 13 is pressed. As a result, the locking bolt 13 in its located outside the range of movement of the core 2 Location held. If there is no authorization, this is omitted the control of the piezoelectric element 14 of the actuator 11 or this is in reverse controlled so that the actuator 11 from the locking bolt 13 moved away. So that the locking bolt 13 of the Force of the locking spring 12 pressed towards the core 2 again.

Figur 2 zeigt den Schließzylinder aus Figur 1 in einer Schnittdarstellung entlang der Linie II - II. Hierbei sind die Bewegungen des Aktors 11 mit Pfeilen gekennzeichnet. Bei einer Ansteuerung des piezoelektrischen Elements 14 wird der Aktor 11 gegen den Sperrriegel 13 gedrückt und hält diesen kraftschlüssig in seiner außerhalb des Bewegungsbereichs des Kerns 1 befindlichen Lage. Bei einer ausbleibenden Ansteuerung des piezoelektrischen Elements 14 reicht ein Kraftschluss zwischen dem Aktor 11 und dem Sperrriegel 13 nicht mehr aus, um diesen gegen die Kraft der Sperrfeder 12 zu halten. Dies führt dazu, dass der Sperrriegel 13 bei einem Drehen des Kerns 2 durch die Kraft der Sperrfeder 12 in neben dem Verdrängungselement 19 angeordnete Taschen 23, 24 gedrückt wird. Damit wird eine weitere Bewegung des Kerns 2 blockiert.Figure 2 shows the lock cylinder of Figure 1 in one Sectional view along the line II - II. Here the movements of the actuator 11 are marked with arrows. When the piezoelectric Elements 14 becomes the actuator 11 against the locking bolt 13 pressed and holds it non-positively in its outside the range of movement of the core 1 located. If there is no activation of the piezoelectric Elements 14 a non-positive connection between the actuator 11 and the locking bolt 13 no longer to counter this to hold the force of the locking spring 12. This leads to, that the locking bolt 13 when the core 2 by the force of the locking spring 12 in addition to the displacement element 19 arranged pockets 23, 24 is pressed. This blocks another movement of the core 2.

Wenn der Schlüssel in den Schließkanal 4, 5 eingeführt und damit der Sperrriegel 13 aus dem Bewegungsbereich des Kerns 2 herausbewegt wird, führt die Unebenheit 15 des gewellten Abschnitts dazu, dass das piezoelektrische Element 14 geringfügig bewegt wird. Eine Bewegung des piezoelektrischen Elements 14 führt zu einem elektrischen Signal, welches von der Steuerelektronik 16 empfangen wird. Die Steuerelektronik 16 wird durch dieses Signal aktiviert und schaltet die Codeempfänger 9, 10 auf Empfangsbereitschaft. Dies führt zu einem besonders geringen Energieverbrauch der Steuerelektronik 16. Weiterhin zeigt Figur 2, dass die Vorspannung des Sperrriegels 13 gegen den Aktor 11 und die Vorspannung der Sperrfeder 12 mittels Stellelementen 25, 26 einstellbar sind. Die Stellelemente 25, 26 sind hier als Stiftschrauben ausgebildet.When the key is inserted into the locking channel 4, 5 and thus the locking bolt 13 from the range of motion of Core 2 is moved out, the unevenness 15 of the corrugated section causing the piezoelectric element 14 is moved slightly. A movement of the piezoelectric Elements 14 leads to an electrical signal, which is received by the control electronics 16. The control electronics 16 is activated by this signal and switches the code receivers 9, 10 to readiness to receive. This leads to a particularly low one Energy consumption of the control electronics 16. Also shows Figure 2 that the bias of the locking bolt 13 against the actuator 11 and the bias of the locking spring 12 by means of Adjusting elements 25, 26 are adjustable. The control elements 25, 26 are designed here as stud screws.

Figur 3 zeigt eine weitere Ausführungsform des Schließzylinders im Querschnitt durch einen Sperrmechanismus 27, welche sich von denen aus den Figuren 1 und 2 vor allem dadurch unterscheidet, dass eine Unebenheit 28 eines Sperrriegels 29 ballig gestaltet ist. Weiterhin ist ein Stellelement 30 zur Einstellung der Vorspannkraft der auf den Sperrriegel 29 einwirkenden Sperrfeder 31 als in die Stufenbohrung 22 eingepresste Kugel ausgebildet. Ein Kern 32 des Schließzylinders weist eine zwischen zwei Taschen 33 angeordnete Hohlkehle 34 zur Aufnahme des freien Endes des Sperrriegels 29 auf. Bei einem anfänglichen Drehen des Kerns 32 wird der Sperrriegel 29 aus dem Bewegungsbereich des Kerns 32 herausgedrückt und bewegt das piezoelektrische Element 14, welches wie zu der Ausführungsform des Schließzylinders nach den Figuren 1 und 2 ein Signal zur Aktivierung der Steuerelektronik 16 liefert. Eine ausbleibende Ansteuerung des Aktors 11 führt dazu, dass der Sperrriegel 29 bei einem weiteren Drehen in die Taschen 33 des Kerns 32 gelangt und dessen Weiterbewegung blockiert. Die Funktion des Sperrmechanismus 27 gestaltet sich wie zu den Ausführungsformen nach den Figuren 1 und 2 beschrieben. Der Aktor 11 weist einen Reibbelag 35 auf.Figure 3 shows a further embodiment of the lock cylinder in cross section through a locking mechanism 27, which differs from those from Figures 1 and 2 above all differs in that an unevenness 28 of a Locking bar 29 is crowned. Furthermore is a Adjustment element 30 for adjusting the pretensioning force the locking bolt 29 acting locking spring 31 as in the Stepped bore 22 pressed ball formed. A core 32 of the lock cylinder has one between two pockets 33 arranged groove 34 for receiving the free end of the locking bolt 29. With an initial spin the core 32, the locking bolt 29 is out of the range of motion of the core 32 is pushed out and moves the piezoelectric Element 14, which is like the embodiment of the lock cylinder according to Figures 1 and 2 Provides signal for activation of the control electronics 16. Failure to control the actuator 11 leads to that the locking bolt 29 with a further turn in the Pockets 33 of the core 32 arrives and its further movement blocked. The function of the locking mechanism 27 is designed the same as for the embodiments according to FIGS. 1 and 2 described. The actuator 11 has a friction lining 35.
