Description

Einrichtung zum elektromagnetischen Verriegeln eines Schließzy- linders eines SchlossesDevice for electromagnetic locking of a lock cylinder of a lock
Die Erfindung bezieht sich auf eine Einrichtung zum elektromag- netischen Verriegeln eines Schließzylinders eines Schlosses mit wenigstens einer in eine Ausnehmung am Umfang des Schließzylin¬ ders eingreifende bewegliche Zuhaltung. Im Zusammenhang mit Schließzylindern sind bereits elektronische Schließzylinder be¬ kannt geworden, bei welchen eine bewegliche Zuhaltung durch einen elektromagnetischen Antrieb in eine Sperrlage gebracht wird oder aus einer derartigen Sperrlage herausbewegt wird. Ein elektromagnetischer Antrieb kann hiebei in besonders einfacher Weise als Hubantrieb ausgebildet sein, wobei eine derartige Aus¬ bildung allerdings den Nachteil einer relativ großen Störan- fälligkeit aufweist. Immer dann, wenn eine bewegliche Zuhaltung durch magnetische Kräfte bewegt werden soll, muß für eine hin¬ reichende Beweglichkeit der beweglichen Zuhaltung Sorge getragen werden, und es besteht die Gefahr, daß durch mechanische Ein¬ flußnahme, beispielsweise durch Schläge auf den Zylinder eine Freigabe der Sperre einer derartigen beweglichen Zuhaltung er¬ folgt, wodurch die Sicherheit nicht gewährleistet ist.The invention relates to a device for the electromagnetic locking of a lock cylinder of a lock with at least one movable tumbler engaging in a recess on the circumference of the lock cylinder. In connection with locking cylinders, electronic locking cylinders have already become known in which a movable tumbler is brought into a locked position by an electromagnetic drive or is moved out of such a locked position. An electromagnetic drive can be designed in a particularly simple manner as a stroke drive, but such a design has the disadvantage of a relatively high susceptibility to faults. Whenever a movable tumbler is to be moved by magnetic forces, care must be taken to ensure sufficient mobility of the movable tumbler, and there is a risk that the mechanical release, for example by striking the cylinder, will release the Such a movable tumbler is blocked, as a result of which safety is not guaranteed.
Die Erfindung zielt nun darauf ab, eine Einrichtung der eingangs genannten Art zu schaffen, bei welcher mit überaus kleinem elek- tromagnetischen Antrieb eine sichere Verriegelung bewirkt werden kann, welche auch bei Erschütterung oder anderer mechanischer oder elektromagnetischer Einflußnahme auf den Sperrzylinder nicht ohne weiteres wiederum aufgehoben werden kann. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Einrichtung im wesentlichen darin, daß die bewegliche Zuhaltung mit einem elek¬ tromagnetischen Drehantrieb zusammenwirkt und in seiner Schlie߬ lage gegen Austauchen aus der Ausnehmung gesichert ist. Dadurch, daß ein elektromagnetischer Drehantrieb vorgesehen ist, im Auf¬ bau ähnlich einem konventionellen, kleinbauenden Motor, und da- durch, daß dieser Drehantrieb dazu verwendet wird, um in einer bestimmten Drehlage ein Austauchen der beweglichen Zuhaltung aus ihrer Verriegelungslage zu verhindern, wird auch mit geringen Stellkräften ein hohes Maß an Sicherheit bewirkt. Die Stellkräf¬ te des Drehantriebes müssen nämlich lediglich dafür ausreichen, um eine Abstützung in Wirkstellung zu bringen, gegen welche die bewegliche Zuhaltung nicht mehr herausbewegt werden kann. Umge- kehrt sind die für die Freigabe erforderlichen Stellkräfte darauf beschränkt, den Drehantrieb in einer Weise zu verdrehen, daß nunmehr die bewegliche Zuhaltung aus einer Ausnehmung, in welcher sie in der Schließlage eintaucht, wiederum austauchen kann. Der elektromagnetische Antrieb bewirkt somit lediglich die Verstellung der Anschlagschulter bzw. Abstützflache für die bewegliche Zuhaltung und es kann daher mit einem überaus klein¬ bauenden und einfachen, nur geringe Kräfte aufbringenden Drehan¬ trieb das Auslangen gefunden werden und trotzdem ein hohes Maß an Sicherheit gegen mechanische Einflüsse bewirkt werden. Um die Freigabe und ein Austauchen der beweglichen Zuhaltung zu ermög¬ lichen, ist mit Vorteil die Ausbildung so getroffen, daß der Drehantrieb in einer definierten Drehlage das Austauchen der beweglichen Zuhaltung aus der Ausnehmung des Schließzylinders freigibt.The invention now aims to provide a device of the type mentioned at the outset, in which a secure locking can be achieved with an extremely small electromagnetic drive, which, in the event of vibration or other mechanical or electromagnetic influence on the locking cylinder, is not easily canceled again can be. To achieve this object, the device according to the invention essentially consists in the fact that the movable tumbler interacts with an electromagnetic rotary drive and is secured in its closed position against emergence from the recess. The fact that an electromagnetic rotary drive is provided, similar in construction to a conventional, small-sized motor, and the fact that this rotary drive is used to prevent the movable tumbler from emerging from its locked position in a certain rotational position with low Actuators brings a high level of security. The actuating forces of the rotary drive only have to be sufficient to bring a support into active position against which the movable tumbler can no longer be moved out. Conversely, the actuating forces required for the release are limited to turning the rotary drive in such a way that the movable tumbler can again emerge from a recess in which it is immersed in the closed position. The electromagnetic drive thus only effects the adjustment of the stop shoulder or support surface for the movable guard locking and it can therefore be found with an extremely small and simple rotary drive which exerts only small forces and nevertheless a high degree of security against mechanical Influences are brought about. In order to enable and release the movable tumbler, the design is advantageously made such that the rotary drive releases the immersion of the movable tumbler from the recess of the locking cylinder in a defined rotational position.
Eine besonders einfache Verriegelung und eine sichere Abstützung der beweglichen Zuhaltung läßt sich dadurch verwirklichen, daß die bewegliche Zuhaltung über ihren Umfang vorragende VorSprünge bzw. Flügel od. dgl. aufweist und federnd in die Ausnehmung des SperrZylinders gedrückt ist und daß die der beweglichen Zuhal¬ tung zugewandte Stirnfläche des Drehantriebes in einer definier¬ ten Drehlage des Drehantriebes Ausnehmungen für die Aufnahme der Vorsprünge bzw. Flügel aufweist. Eine derartige Ausbildung er¬ laubt die Verwendung eines besonders kompakten Drehantriebes, wobei mit Vorteil die Ausbildung so getroffen ist, daß der Dreh¬ antrieb eine in z-Richtung auf der Mantelfläche eines Zylinders bewickelte Spule als Stator und einen in x-Richtung magneti- sierten, insbesondere röhr- oder hülsenförmigen Rotor aufweist. Die röhr- bzw. hülsenförmige Ausbildung des Rotors erlaubt die Anordnung einer Feder für das federnde Andrücken der beweglichen Zuhaltung und erlaubt es weiters, daß eine derartige bewegliche Zuhaltung in den zentralen Hohlraum eines derartigen Rotors hin- eingedrückt werden kann, wenn die VorSprünge bzw. Flügel nicht durch eine entsprechende Anschlagfläche an einem Eintauchen in den Rotor gehindert werden.A particularly simple locking and secure support of the movable tumbler can be achieved in that the movable tumbler has protrusions or wings or the like protruding over its circumference and is pressed resiliently into the recess of the locking cylinder and in that the movable tumbler facing end face of the rotary drive in a defined rotational position of the rotary drive has recesses for receiving the projections or wings. Such a design permits the use of a particularly compact rotary drive, the design advantageously being such that the rotary drive has a coil wound as a stator in the z direction on the lateral surface of a cylinder and a magnetized magnet in the x direction , in particular tubular or sleeve-shaped rotor. The tubular or sleeve-shaped design of the rotor permits the arrangement of a spring for the resilient pressing of the movable tumbler and furthermore allows such a movable tumbler into the central cavity of such a rotor. can be pressed in if the projections or wings are not prevented from immersing into the rotor by a corresponding stop surface.
Um ein einfaches Ausweichen der beweglichen Zuhaltung bei Frei¬ gabe des Hubes bzw. des Weges der beweglichen Zuhaltung entgegen der Kraft einer Feder zu bewirken ist mit Vorteil die Ausbildung so getroffen, daß die Ausnehmung am Umfang des Schließzylinders Schrägflächen aufweist, über welche die bewegliche Zuhaltung bei Verdrehen des Schließzylinders bei Freigabe der Austauchbewegung durch den Drehantrieb gleitend radial auswärts geführt ist. Eine derartige Ausbildung führt dazu, daß die bewegliche Zuhaltung über die Schrägflächen gleitend nach auswärts gedrückt wird, wobei die bewegliche Zuhaltung in das Innere des hülsen- bzw. rohrförmigen Rotors eintauchen kann und die Flügel bzw. Vor¬ sprünge in entsprechende Ausnehmungen an der Stirnseite des Rotors eintauchen können.In order to cause a simple evasion of the movable tumbler when the stroke or the path of the movable tumbler is released against the force of a spring, the design is advantageously made such that the recess on the circumference of the locking cylinder has inclined surfaces over which the movable tumbler when the locking cylinder is rotated and the exchange movement is released, the rotary drive slides radially outward. Such a design leads to the fact that the movable tumbler is pushed outwards slidingly over the inclined surfaces, the movable tumbler being able to dip into the interior of the sleeve or tubular rotor and the wings or projections into corresponding recesses on the end face of the Can immerse the rotor.
Um bei einer derartigen Ausbildung zusätzlich den Vorteil zu schaffen, daß dann, wenn die Ausbildung wieder stromlos wird, eine definierte Ausgangslage automatisch eingenommen wird, ist die Ausbildung mit Vorteil so getroffen, daß zusätzlich wenig¬ stens ein ortsfest angeordneter, in Längsrichtung magnetischer Teil, z.B. Ferrit angeordnet ist, welcher den magnetisierten Ro- tor bei stromloser Spule in eine definierte Drehlage bringt. Mit einer derartigen Ausbildung kann nach einem federnden Rückstel¬ len der beweglichen Zuhaltung in ihre Sperrlage eine automa¬ tische Verdrehung des Rotors in eine definierte Ausgangsposition bewirkt werden, bei welcher wiederum die Anschlagflächen zur Ab- Stützung der Vorsprünge bzw. Flügel der beweglichen Zuhaltung zur Wirkung gelangen und ein nochmaliges Verdrehen des Sperrzy¬ linders nicht mehr möglich ist, da nunmehr die bewegliche Zuhal¬ tung nicht mehr ausweichen kann.In order to provide the additional advantage of such a design that when the design is de-energized again, a defined starting position is automatically assumed, the design is advantageously made such that in addition at least one fixedly arranged, longitudinally magnetic part e.g. Ferrite is arranged, which brings the magnetized rotor into a defined rotational position when the coil is de-energized. With a configuration of this type, after the resilient return of the movable tumbler into its blocking position, the rotor can be automatically rotated into a defined starting position, in which in turn the stop surfaces for supporting the projections or wings of the movable tumbler are effective arrive and a further twisting of the locking cylinder is no longer possible, since the movable tumbler can no longer evade.
Wie bereits erwähnt, ist die Ausbildung in vorteilhafter Weise so getroffen, daß die Stirnfläche des Rotors Ausnehmungen in Form von Schlitzen für die Aufnahme der Vorsprünge bzw. Flügel der beweglichen Zuhaltung aufweist, wobei derartige Ausnehmungen beispielsweise nach Art einer Schraubendrehernut ausgebildet sein können, welche mit entsprechenden Flügeln des Bolzens in der Kontur übereinstimmen, um ein Ausweichen des Bolzens bei entsprechender Drehlage des Rotors zu ermöglichen. Wie gleich¬ falls bereits eingangs erwähnt, erlaubt es insbesondere die röhr- oder hülsenförmige Ausbildung des Rotors, eine Feder koa¬ xial zum Rotor im Inneren des Rotors anzuordnen, sodaß insgesamt eine besonders kompakte und einfache Bauweise bewirkt wird, welche ohne weiteres in einem- konventionellen Schloß mit üb¬ licher Kontur angeordnet werden kann. Die Verriegelung wird so¬ mit von einem Drehantrieb bewirkt, welcher zwei oder vier An¬ schlüsse bewirkt. Bei zwei Anschlüssen ist mit Rücksicht auf die vorgegebenen Feldlinien eine Rotation um 90° aus der Ruhe- position vorgesehen, wobei dann, wenn die Spule nicht mehr mit Strom durchflössen ist, der Rotor sich entsprechend einem starr angeordneten magnetischen Teil, z.B. Ferrit, ausrichten wird. Bei Verwendung von mehr als einem Ferrit kann auch eine bistabi¬ le Lage erzielt werden, bei welcher eine von zwei möglichen End- Positionen wahlweise eingenommen werden kann, wobei in der End¬ position entweder eine Freigabe oder eine Sperre der Bewegung des Verriegelungsstiftes bewirkt werden kann. Bei Verwendung ei¬ ner Spule mit vier um 90° versetzten Polen, bei welcher jeweils gegenüberliegende Pole zusammengehören, braucht für die Dreh- bewegung das Feld des Ferriten nicht überwunden zu werden. Allerdings ist hier ein Dauerström notwendig, da ja dann bei Stromausfall eine stabile Ruhelage nicht existiert.As already mentioned, the design is advantageously made such that the end face of the rotor has recesses in the form of slots for receiving the projections or wings of the movable tumbler, wherein such recesses can be designed, for example, in the manner of a screwdriver groove, which correspond in shape to corresponding wings of the bolt in order to allow the bolt to deflect when the rotor is in the corresponding rotational position. As already mentioned at the beginning, in particular the tubular or sleeve-shaped design of the rotor allows a spring to be arranged coaxially to the rotor in the interior of the rotor, so that overall a particularly compact and simple construction is achieved, which is easily accomplished in one conventional lock with a conventional contour can be arranged. The locking is thus effected by a rotary drive which effects two or four connections. With two connections, a rotation through 90 ° from the rest position is provided with regard to the specified field lines, and when the coil is no longer flowed through with current, the rotor will align itself according to a rigidly arranged magnetic part, for example ferrite . If more than one ferrite is used, a bistable position can also be achieved, in which one of two possible end positions can optionally be assumed, in the end position either releasing or blocking the movement of the locking pin . When using a coil with four poles offset by 90 °, in which opposite poles belong together, the field of the ferrite need not be overcome for the rotational movement. However, a continuous flow is necessary here, since a stable rest position does not exist in the event of a power failure.
Ein besonderer Vorteil der erfindungsgemäßen Ausbildung besteht darin, daß durch die geforderte Drehbewegung der Abstutzflächen eine äußere Einflußnahme bzw. Manipulation kaum möglich er¬ scheint. Wenig bewegte Teile führen darüberhinaus zu einem ge¬ ringen Verschleiß der Bauteile, wobei durch die besonders gerin¬ ge Anzahl von Bauteilen die einzelnen Bauteile auch entsprechend robuster ausgeführt werden können. Die Erfindung wird nachfolgend anhand von in der Zeichnung sche¬ matisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.l eine schematische Ansicht eines Schlosses mit der erfindungsgemäßen elektromagnetischen Verriegelung, Fig.2 ein Detail der Fig.l in der Ansicht entprechend der Rich¬ tung des Pfeiles II, Fig.3 eine Darstellung analog der Fig.l mit um 90° verdrehtem Rotor, wobei Fig.4 wiederum eine Teilansicht entprechend dem Pfeil IV der Fig.3 darstellt, Fig.5, Fig.6 und Fig.7 Varianten der Ausgestaltung bei Verwendung eines Ferriten zur selbständigen Einnahme einer definierten Ausgangslage bei stromloser Spule.A particular advantage of the design according to the invention is that external manipulation or manipulation hardly seems possible due to the required rotational movement of the support surfaces. In addition, parts that are only slightly moved result in low wear of the components, and the particularly small number of components means that the individual components can also be made correspondingly more robust. The invention is explained in more detail below with reference to exemplary embodiments schematically shown in the drawing. 1 shows a schematic view of a lock with the electromagnetic lock according to the invention, FIG. 2 shows a detail of FIG. 1 in the view corresponding to the direction of the arrow II, FIG. 3 shows a representation analogous to that of FIG 90 ° rotated rotor, FIG. 4 again showing a partial view corresponding to the arrow IV of FIG. 3, FIGS. 5, 6 and 7, variants of the configuration when using a ferrite for the independent assumption of a defined starting position with a currentless coil.
In Fig.l ist ein Schloß 1 ersichtlich, dessen Schließzylinder 2 an seinem Umfang eine Ausnehmung 3 für die Aufnahme einer beweg- liehen Zuhaltung 4 aufweist. Die bewegliche Zuhaltung 4 taucht aufgrund der Kraft der Feder 5 in die Ausnehmung 3 ein. Die Aus¬ nehmung 3 weist Schrägflächen 6 auf, welche mit der beweglichen Zuhaltung 4 zusammenwirken. Wenn der Rotor 7 des Elektromotors 8 in der in Fig.l dargestellten Position steht, wird ein Aus- weichen der beweglichen Zuhaltung 4 in den Hohlraum 9 des Rotors 7 behindert, da die seitlichen Vorsprünge bzw. Flügel 10 der beweglichen Zuhaltung 4 mit der Stirnfläche 11 des Rotors 7 kollidieren. Die Spule des Elektromotors 8 ist mit 12 ange¬ deutet, wobei die Wicklungen der Spule in Richtung der z-Achse erfolgen. Der Rotor 7 ist in Richtung der x-Achse magnetisiert, wodurch bei Bestromung eine Verdrehung des Rotors im Sinne des Pfeiles 13 erfolgt.In Fig.l a lock 1 can be seen, the lock cylinder 2 has on its periphery a recess 3 for receiving a movable tumbler 4. The movable tumbler 4 dips into the recess 3 due to the force of the spring 5. The recess 3 has inclined surfaces 6 which cooperate with the movable tumbler 4. If the rotor 7 of the electric motor 8 is in the position shown in FIG. 1, the moving tumbler 4 is prevented from moving into the cavity 9 of the rotor 7, since the lateral projections or wings 10 of the movable tumbler 4 with the end face 11 of the rotor 7 collide. The coil of the electric motor 8 is indicated by 12, the coils being wound in the direction of the z-axis. The rotor 7 is magnetized in the direction of the x-axis, as a result of which the rotor is rotated in the direction of the arrow 13 when energized.
In der Darstellung nach Fig.2 ist ersichtlich, daß die Stirn- fläche 11 des Rotors 7 Ausnehmungen 14 aufweist, in welche nach entsprechender Verdrehung des Rotors 7 im Sinne des Pfeiles 13 die Flügel bzw. seitlichen Vorsprünge 10 der beweglichen Zuhal¬ tung 4 eintauchen können. In Fig.l und 2 ist zusätzlich noch ein ortsfester Ferrit 15 ersichtlich, welcher ein Verdrehen des Ro- tors 7 bei Stromlosigkeit der Spule 12 in eine definierte Aus¬ gangsläge bewirkt. Bei den Darstellungen nach den Fig.3 und 4 ist jeweils eine um 90° verdrehte Position ersichtlich, welche dann eingenommen wird, wenn die Spule 12 mit Strom durchflössen ist. Wie insbe¬ sondere in Fig.3 ersichtlich ist, können in dieser Drehlage nun- mehr die seitlichen Vorsprünge 10 der beweglichen Zuhaltung 4 in die Ausnehmungen 14 des Rotors 7 eintauchen, wobei die Kraft der Feder 5 überwunden werden muß. Bei einer Verdrehung des SperrZy¬ linders im Sinne des Doppelpfeiles 16 wirken die Schrägflächen 6 auf die bewegliche Zuhaltung 4 im Sinne einer axialen Verschie- bung in Richtung des Doppelpfeiles 17, sodaß ein Eintauchen der beweglichen Zuhaltung 4 in den zentralen axialen Hohlraum 9 des Rotors ermöglicht wird. Die entsprechende Seitenansicht entspre¬ chend dem Pfeil IV auf Spule und Rotor ist wiederum in Fig.4 dargestellt.2 shows that the end face 11 of the rotor 7 has recesses 14, into which the wings or lateral projections 10 of the movable tumbler 4 are immersed after corresponding rotation of the rotor 7 in the direction of the arrow 13 can. FIGS. 1 and 2 also show a stationary ferrite 15, which causes the rotor 7 to rotate into a defined starting position when the coil 12 is de-energized. In the representations according to FIGS. 3 and 4, a position rotated by 90 ° can be seen, which position is assumed when the coil 12 has current flowing through it. As can be seen in particular in FIG. 3, the lateral projections 10 of the movable tumbler 4 can now dip into the recesses 14 of the rotor 7 in this rotational position, the force of the spring 5 having to be overcome. When the locking cylinder is rotated in the sense of the double arrow 16, the inclined surfaces 6 act on the movable tumbler 4 in the sense of an axial displacement in the direction of the double arrow 17, so that the movable tumbler 4 can be immersed in the central axial cavity 9 of the rotor becomes. The corresponding side view corresponding to the arrow IV on the coil and rotor is again shown in FIG.
In den Darstellungen nach Fig.5, 6 und 7 sind jeweils unter¬ schiedliche Anordnungen von Ferriten 15 ersichtlich. Die Magne¬ tisierungsrichtung des Rotors entspricht hiebei einem der Pfeile 18, je nachdem ob die Spule 12 stromlos ist oder nicht. Bei der Darstellung nach Fig.7 wird eine bistabile Verriegelung ermög¬ licht, wobei bei Stromlosigkeit eine der beiden Positionen ent¬ sprechend den Pfeilen 18 eingenommen wird. Die Endpunkte der Ferrite liegen jeweils über den Polen der Spulen, welche schema¬ tisch mit a, b, c und d angedeutet sind. Die Spule wird bei der Ausbildung nach Fig.7 lediglich zum Umschalten von einer sta¬ bilen Position in die andere verwendet, wodurch ein besonders geringer Strombedarf erzielt wird, da eine Dauerbestromung nicht mehr notwendig ist. Bei den Ausbildungen nach Fig.5 bzw. 6 ist jeweils für die Verriegelung oder die Entriegelung ein ent- sprechender Dauerstrom erforderlich. 5, 6 and 7 each show different arrangements of ferrites 15. The magnetization direction of the rotor corresponds to one of the arrows 18, depending on whether the coil 12 is currentless or not. In the illustration according to FIG. 7, a bistable locking is made possible, one of the two positions being adopted according to the arrows 18 when there is no current. The end points of the ferrites each lie above the poles of the coils, which are schematically indicated by a, b, c and d. In the embodiment according to FIG. 7, the coil is only used to switch from one stable position to the other, as a result of which a particularly low current requirement is achieved, since a constant current supply is no longer necessary. In the embodiments according to FIGS. 5 and 6, a corresponding continuous current is required for the locking or unlocking.
