Description

Die vorliegende Erfindung betrifft eine Blockiereinrichtung zur zumindest teilweisen Blockierung einer Relativbewegung zwischen einem unbeweglichen und einem beweglichen Teil einer Vorrichtung.The present invention relates to a blocking device for at least partially blocking a relative movement between an immovable and a movable part of a device.

Aus der deutschen Patentanmeldung 10 2005 042 883.5 ist eine gattungsgemäße Blockiereinrichtung in einem Bedienelement bekannt, bei dem eine Kugel in Eingriff mit einem in dem beweglichen Teil des Bedienelements eingebrachten Rastprofil bringbar ist, um zumindest eine Bewegung des beweglichen Teils zu blockieren. Dabei wird die Kugel von einem Elektromagneten zwischen zwei Endpositionen verfahren. Der Elektromagnet ist auf einem der Schenkel eines U-förmigen Eisenkerns angeordnet. Ein Permanentmagnet liegt mit einem seiner Pole an der Verbindung zwischen den beiden Schenkeln an. Ist der Elektromagnet unbestromt, so bildet der Permanentmagnet im Eisenkern ein Magnetfeld aus, das in beiden Schenkeln des Eisenkerns identisch ist und die Kugel in ihrer aktuellen Position hält. Während der Elektromagnet bestromt ist ergibt sich im Eisenkern ein überlagertes Magnetfeld, durch das sich die Kugel aus ihrer aktuellen Position in die andere Endposition bewegt.From the German patent application 10 2005 042 883.5 a generic blocking device is known in an operating element, in which a ball can be brought into engagement with an introduced in the movable part of the operating element latching profile to block at least one movement of the movable part. The ball is moved by an electromagnet between two end positions. The electromagnet is arranged on one of the limbs of a U-shaped iron core. A permanent magnet abuts one of its poles at the junction between the two legs. If the electromagnet is de-energized, the permanent magnet in the iron core forms a magnetic field that is identical in both legs of the iron core and holds the ball in its current position. While the electromagnet is energized, a superimposed magnetic field results in the iron core, through which the ball moves from its current position to the other end position.

Die vorstehend beschriebene Blockiereinrichtung weist mehrere Nachteile auf. So muss der Permanentmagnet ein starkes Magnetfeld erzeugen, um die Kugel auch bei Erschütterungen in ihrer Position zu halten. Wird die Kugel dennoch durch Erschütterungen oder sonstige ungewollte Einflüsse aus ihrer Position gebracht, so besteht die Möglichkeit, dass die Kugel ungewollt in ihre andere Endlage gerät und dort gehalten wird.The blocking device described above has several disadvantages. Thus, the permanent magnet must generate a strong magnetic field in order to keep the ball in position even with vibrations. If the ball is still brought from its position by vibrations or other unwanted influences, there is the possibility that the ball unintentionally gets into its other end position and held there.

Bei der aus dem Stand der Technik bekannten Blockiereinrichtung müssen die einzelnen Komponenten sehr präzise gefertigt und angeordnet werden. So müssen die Enden der Schenkel des Eisenkerns über ihre gesamte Stirnfläche einen gleichbleibenden Abstand zur Lauffläche der Kugel aufweisen. Dieser Abstand darf einen gewissen Maximalwert nicht überschreiten, da die auf die Kugel wirkende Magnetkraft sonst zu klein wäre. Außerdem muss der Abstand zwischen den Schenkeln des Eisenkerns geringfügig größer sein als der Abstand der beiden Endpositionen der Kugel, damit sich die Endpositionen der Kugel in einem ausreichend starken Bereich des Magnetfeldes befinden. Dies führt zu Einschränkungon bei der Gestaltung des Bedienelementes.In the blocking device known from the prior art, the individual components must be manufactured and arranged very precisely. Thus, the ends of the legs of the iron core over their entire end face must have a constant distance from the running surface of the ball. This distance must not exceed a certain maximum value, since the magnetic force acting on the ball would otherwise be too small. In addition, the distance between the legs of the iron core must be slightly larger than the distance between the two end positions of the ball, so that the end positions of the ball in a sufficiently strong area of the magnetic field. This leads to restriction in the design of the control.

Aus der EP 0 796 756 A2 ist eine Bedienvorrichtung für menügesteuerte Funktionen eines Fahrzeugs, die auf einem Bildschirm symbolisch darstellbar und durch ein Betätigungsteil anwählbar sind, bekannt. Das Betätigungsteil ist zwischen mechanischen Anschlägen in eine Stellung bewegbar, die der Lage des Symbols der anwählbaren Funktion auf der Bildschirmoberfläche entspricht und die bei einer Änderung der anwählbaren Funktion durch Bewegen des Betätigungsteils eine haptische Rückmeldung an das Betätigungsteil erfolgt.From the EP 0 796 756 A2 is an operating device for menu-driven functions of a vehicle, symbolically displayed on a screen and can be selected by an operating part known. The actuating member is movable between mechanical stops in a position corresponding to the position of the symbol of the selectable function on the screen surface and which takes place in a change of the selectable function by moving the operating part a haptic feedback to the operating part.

Die US 2004/0089039 A1 offenbart ein blockierbares Schloss, welches ein um eine Achse drehbares Betätigungselement umfasst. Das Schloss weist einen Riegel auf, der elektromechanisch zwischen zwei Positionen bewegt werden kann. In einer ersten Position blockiert der Riegel eine Drehbewegung des Betätigungselements, in einer zweiten Position gibt der Riegel das Betätigungselement frei. Die Position des Riegels wird anhand eines Zugangscodes gesteuert, der auf einem geeigneten separat ausgebildeten Speichermittel gespeichert ist.The US 2004/0089039 A1 discloses a lockable lock comprising an actuator rotatable about an axis. The lock has a latch that can be moved electromechanically between two positions. In a first position, the bolt blocks a rotational movement of the actuating element, in a second position, the bolt releases the actuating element. The position of the bar is controlled by means of an access code stored on a suitable separately formed storage means.

Die EP 0 498 247 A1 betrifft eine Vorrichtung, mittels derer Geräusche und Vibrationen, die beim Betätigen und Entriegeln einer durch eine angetriebene Kabinentür mitgenommenen Schachttür entstehen, weitgehend vermieden werden können. Zu diesem Zweck sind ein an der Schachttür befestigtes erstes, und ein an der Kabinentür befestigtes zweites Kupplungsglied als Magnete ausgebildet und derart angeordnet, dass ein Nordpol (N) des ersten Kupplungsgliedes einem Nordpol des zweiten Kupplungsgliedes, und ein Südpol (S) des ersten Kupplungsglledes einem Südpol des zweiten Kupplungsgliedes durch einen Luftspalt getrennt in Bewegungsrichtung der Türen gegenüberliegen. An einem Verriegelungsglied der Schachttür ist ein weiterer Magnet vorgesehen, dessen einer Pol in Bewegungsrichtung der Türen einem gleichnamigen Pol des zweiten Kupplungsgliedes mit Luftspalt gegenüberliegt. Bei einem Halt einer Kabine auf einem Stockwerk wird durch die abstoßenden Kräfte der Magnete zuerst die Schachttür berührungslos entriegelt und dann beim Öffnen der Kabinentür berührungslos mitgenommen,The EP 0 498 247 A1 relates to a device by means of which noise and vibrations that occur when you press and unlock a taken by a powered car door door, can be largely avoided. For this purpose, a fixed to the shaft door first, and attached to the car door second coupling member are formed as magnets and arranged such that a north pole (N) of the first coupling member a north pole of the second coupling member, and a south pole (S) of the first Kupplungsglledes a south pole of the second coupling member separated by an air gap in the direction of movement of the doors. At a locking member of the shaft door, a further magnet is provided, one pole of which is opposite in the direction of movement of the doors of a like pole of the second coupling member with air gap. When a car stops on a floor, the shaft door is first unlocked contactlessly by the repulsive forces of the magnets and then taken along without contact when the car door is opened,

Aus der EP 1030 010 A2 ist ein Bedienelement bekannt, welches elektromechanisch in einen Bedienzustand und einen Blockierzustand versetzt werden kann. Hierzu ist das mechanische Bedienteil als Anker eines Elektromagneten ausgebildet und zwischen zwei Stellungen rotierbar. In der ersten Stellung ist die Betätigung des Bedienteils mechanisch blockiert, in der zweiten Stellung ist das Bedienteil betätigbar.From the EP 1030 010 A2 is known an operating element which can be electromechanically placed in an operating state and a blocking state. For this purpose, the mechanical control unit is designed as an armature of an electromagnet and rotatable between two positions. In the first position, the operation of the control panel is mechanically blocked, in the second position, the control panel is actuated.

Aus der GB 881,197 C1 ist ein magnetisch betätigbares Sicherheitsschloss bekannt, welches ein Riegelelement umfasst, das um eine Drehachse verschwenkbar ist. Dabei ist das Riegelelement über eine Feder mechanisch in eine Richtung vorgespannt, in der eine am Riegelelement ausgebildete Sperrklinke in Eingriff gelangt. Weiter ist am Riegelelement ein Permanentmagnet ausgebildet, der mit einem Elektromagneten zusammenwirkt, dergestalt dass das Riegelelement gegen die Vorspannung der Feder in eine Freigabestellung verschwenkt werden kann.From the GB 881,197 C1 a magnetically actuable safety lock is known, which comprises a locking element which is pivotable about an axis of rotation. In this case, the locking element is biased by a spring mechanically in a direction in which a latch formed on the locking element engages. Next, a permanent magnet is formed on the locking element, which cooperates with an electromagnet, such that the locking element can be pivoted against the bias of the spring in a release position.

Es ist die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Blockiereinrichtung bereitzustellen, die die vorgenannten Nachteile nicht aufweist.It is the object of the present invention to provide a generic blocking device which does not have the aforementioned disadvantages.

Gelöst wird diese Aufgabe erfindungsgemäß durch die Merkmale des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungsformen sind in den abhängigen Patentansprüchen angegeben.This object is achieved according to the invention by the features of claim 1. Further advantageous embodiments are specified in the dependent claims.

Eine Blockiereinrichtung zur zumindest teilweisen Blockierung einer Relativbewegung zwischen einem unbeweglichen und einem beweglichen Teil einer Vorrichtung weist gemäß Patentanspruch 1 mindestens einen Permanentmagneten, einen Elektromagneten auf einem ferromagnetischen Kern, ein Rastprofil im beweglichen Teil und ein Blockierelement, das in Eingriff mit dem Rastprofil bringbar ist, auf. Dabei ist der Permanentmagnet beweglich in der Vorrichtung angeordnet und zwischen zumindest zwei Endpositionen verfahrbar.A blocking device for at least partially blocking a relative movement between an immovable and a movable part of a device has according to claim 1 at least one permanent magnet, an electromagnet on a ferromagnetic core, a locking profile in the movable part and a blocking element, which can be brought into engagement with the locking profile, on. In this case, the permanent magnet is movably arranged in the device and movable between at least two end positions.

Der Permanentmagnet ist zwischen dem offenen Ende des ferromagnetischen Kerns und dem Blockierelement angeordnet. Bei dem Blockierelement handelt es sich beispielsweise um eine magnetisierbare Kugel. Prinzipiell kann das Blockierelement jede geeignete Form aufweisen. Das Blockierelement besteht aus einem magnetischen oder magnetisierbaren Material, damit durch ein Magnetfeld eine Kraft auf das Blockierelement ausgeübt wird. In jeder seiner Endpositionen befindet sich der Permanentmagnet im Bereich des Endes eines Schenkels des ferromagnetischen Kerns. Das Magnetfeld des Permanentmagneten erstreckt sich in die Schenkel des ferromagnetischen Kerns und hält den Permanentmagneten damit in seiner Position.The permanent magnet is disposed between the open end of the ferromagnetic core and the blocking element. The blocking element is, for example, a magnetizable ball. In principle, the blocking element can have any suitable shape. The blocking element consists of a magnetic or magnetizable material, so that a force is exerted on the blocking element by a magnetic field. In each of its end positions, the permanent magnet is located in the region of the end of a Leg of the ferromagnetic core. The magnetic field of the permanent magnet extends into the legs of the ferromagnetic core and thus holds the permanent magnet in position.

Ein Positionswechsel des Permanentmagneten wird dadurch erreicht, dass der Elektromagnet bestromt wird und sich infolgedessen ein Magnetfeld im ferromagnetischen Kern ausbildet. Die Stromrichtung durch den Elektromagneten und damit die Richtung des Magnetfeldes im ferromagnetischen Kern wird so gewählt, dass sich an dem Schenkel, in dessen Bereich sich der Permanentmagnet befindet, der Magnetpol ausbildet, der dem dem ferromagnetischen Kern zugewandten Pol des Permanentmagneten entspricht. Dies führt zu einer Abstoßung des Permanentmagneten aus seiner aktuellen Lage in die andere Endposition. Bevorzugt ist der bewegliche Permanentmagnet derart geführt, dass ein Umkippen des Permanentmagneten verhindert wird. Umkippen bedeutet in diesem Zusammenhang, dass sich der Permanentmagnet derart dreht, dass dem ferromagnetischen Kern der andere Magnetpol zugewandt ist.A change in position of the permanent magnet is achieved in that the electromagnet is energized and, as a result, forms a magnetic field in the ferromagnetic core. The current direction through the electromagnet and thus the direction of the magnetic field in the ferromagnetic core is selected so that the magnetic pole forms on the leg, in the region of which the permanent magnet is located, which corresponds to the ferromagnetic core facing pole of the permanent magnet. This leads to a repulsion of the permanent magnet from its current position to the other end position. Preferably, the movable permanent magnet is guided in such a way that overturning of the permanent magnet is prevented. Tipping over in this context means that the Permanent magnet rotates such that the ferromagnetic core faces the other magnetic pole.

Das Blockierelement, das sich im Bereich des Magnetfelds des Permanentmagneten befindet, folgt der Bewegung des Permanentmagneten und ist so beispielsweise ebenfalls zwischen zwei Endpositionen verfahrbar. In einer Endposition ist das Blockierelement im Eingriff mit dem Rastprofil im beweglichen Teil der Vorrichtung und blockiert so die Bewegung des beweglichen Teils zumindest in einer Richtung. In einer anderen Endposition ist das Blockierelement nicht im Eingriff mit dem Rastprofil. Durch die relative Nähe zwischen dem Blockierelement und dem Permanentmagneten führt bereits ein vergleichsweise schwacher Permanentmagnet zu einer starken Magnetkraft auf das Blockierelement und somit zu einer hohen Vibrationsfestigkeit.The blocking element, which is located in the region of the magnetic field of the permanent magnet, follows the movement of the permanent magnet and is, for example, likewise movable between two end positions. In an end position, the blocking element is in engagement with the locking profile in the movable part of the device and thus blocks the movement of the movable part in at least one direction. In another end position, the blocking element is not engaged with the locking profile. Due to the relative proximity between the blocking element and the permanent magnet, a comparatively weak permanent magnet already leads to a strong magnetic force on the blocking element and thus to a high vibration resistance.

Der ferromagnetische Kern, der beispielsweise aus Eisen besteht, ist im Wesentlichen U-förmig ausgebildet. Auch können die Abstände zwischen dem ferromagnetischen Kern und dem Permanentmagneten beziehungsweise dem Permanentmagneten und dem deutlich größer gewählt werden als bei dem aus dem Stand der Technik bekannten Bedienelement.The ferromagnetic core, which consists for example of iron, is substantially U-shaped. Also, the distances between the ferromagnetic core and the permanent magnet or the permanent magnet and be chosen to be much larger than in the known from the prior art operating element.

Der auf dem ferromagnetischen Kern angeordnete Elektromagnet und der bewegliche Permanentmagnet bilden ein mechanisches, bi-stabiles Flip-Flop, wobei das Blockierelement der Position des Permanentmagneten folgt.The electromagnet disposed on the ferromagnetic core and the movable permanent magnet form a mechanical, bi-stable flip-flop, the blocking element following the position of the permanent magnet.

Die erfindungsgemäße Verwendung eines beweglichen Permanentmagneten hat einen weiteren Vorteil, wenn das Blockierelement die Bewegung des beweglichen Teils der Vorrichtung blockiert. In diesem Fall ist das Blockierelement in der Rastkontur verklemmt und kann daher bei entsprechend großer Klemmkraft seine Position nicht verlassen. In einem Bedienelement aus dem Stand der Technik wird der Positionswechsel der Kugel durch eine kurze Bestromung des Elektromagneten erzielt. Ist die Kugel während der Bestromung eingeklemmt, so ändert sie ihre Position nicht. In einer erfindungsgemäßen Blockiereinrichtung ist der Permanentmagnet jedoch stets beweglich und ändert auch bei eingeklemmtem Blockierelement seine Position, wenn der Elektromagnet entsprechend bestromt wird. Das Blockierelement folgt der Bewegung des Permanentmagneten, sobald es nicht mehr eingeklemmt ist, auch wenn der Elektromagnet nicht mehr bestromt ist.The use according to the invention of a movable permanent magnet has a further advantage when the blocking element blocks the movement of the movable part of the device. In this case, the blocking element is jammed in the locking contour and therefore can not leave its position with a correspondingly large clamping force. In a control element of the prior art, the position change of the ball is achieved by a short energization of the electromagnet. If the ball is trapped during energization, it does not change its position. In a blocking device according to the invention, however, the permanent magnet is always movable and changes its position even when the blocking element is clamped, when the electromagnet is energized accordingly. The blocking element follows the movement of the permanent magnet as soon as it is no longer clamped, even when the electromagnet is no longer energized.

Die erfindungsgemäße Blockiereinrichtung ist beispielsweise als Aktuator in einem Bedienelement, insbesondere einem Drehsteller oder einem Joystick einsetzbar. Bei einer als Drehsteller ausgebildeten Vorrichtung wird mit der Blockiereinrichtung zum Beispiel eine Drehrichtung gesperrt oder bei einem Joystick eine Kipprichtung. Das Bedienelement mit einer erfindungsgemäßen Blockiereinrichtung ist insbesondere in einem Kraftfahrzeug einsetzbar.The blocking device according to the invention can be used, for example, as an actuator in an operating element, in particular a turntable or a joystick. In a device designed as a turntable, a rotation direction is blocked with the blocking device, for example, or a tilting direction in the case of a joystick. The control element with a blocking device according to the invention can be used in particular in a motor vehicle.

Alternativ handelt es sich bei der Vorrichtung beispielsweise um eine Tür, insbesondere um eine Tür in einem Kraftfahrzeug. Mit der Blockiereinrichtung ist das Öffnen der Tür blockierbar und somit die Tür abschließbar, beispielsweise zur Zugangsbeschränkung oder als Kindersicherung. Weiterhin alternativ handelt es sich bei der Vorrichtung um ein Zündschloss. Mittels der Blockiereinrichtung ist der Zündschlüssel im Schloss arretierbar, sodass der Schlüssel beispielsweise während der Fahrt nicht abgezogen werden kann.Alternatively, the device is, for example, a door, in particular a door in a motor vehicle. With the blocking device, the opening of the door is blocked and thus the door lockable, for example, to restrict access or as a child safety. Further alternatively, the device is an ignition lock. By means of the blocking device, the ignition key can be locked in the lock, so that the key can not be removed, for example, while driving.

In noch weiteren Alternativen handelt es sich bei der Vorrichtung um eine Betätigungsvorrichtung, beispielsweise um eine Verstellvorrichtung für ein Lenkrad oder einen Sitz insbesondere in einem Kraftfahrzeug. Somit wird beispielsweise verhindert, dass das Lenkrad oder der Sitz während der Fahrt verstellt werden kann.In still other alternatives, the device is an actuating device, for example an adjusting device for a steering wheel or a seat, in particular in a motor vehicle. Thus, it is prevented, for example, that the steering wheel or the seat can be adjusted while driving.

Figur 1 zeigt eine Schnittdarstellung einer Vorrichtung in Form eines als Drehsteller 1 ausgebildeten Bedienelementes mit einem unbeweglichen Teil 2, einem zumindest teilweise blockierbaren beweglichen Teil 3 und zwei efindungsgemäßen Blockiereinrichtungen. In den unbeweglichen Teil 2 sind Taschen 8 und 13 eingebracht, in denen Kugeln 7 beziehungsweise 12 frei beweglich gelagert sind. Angrenzend an die Taschen 8 und 13 sind Führungselemente 15 beziehungsweise 16 angeordnet, die die translatorisch beweglichen Permanentmagnete 6 beziehungsweise 11 aufnehmen. An die Führungselemente 15 und 16 grenzen U-förmige Eisenkerne 5 beziehungsweise 10, die jeweils einen Elektromagneten 4 beziehungsweise 9 tragen. Die Permanentmagnete 6 und 11 sind im vorliegenden Beispiel in die Papierebene hinein und aus der Papierebene heraus beweglich. Die Südpole der Permanentmagnete 6 und 11 sind punktiert dargestellt, die Nordpole schraffiert. FIG. 1 shows a sectional view of a device in the form of a trained as a turntable 1 operating element with a stationary part 2, an at least partially blockable movable part 3 and two locking devices according to the invention. In the immovable part 2 pockets 8 and 13 are introduced, in which balls 7 and 12 are mounted freely movable. Adjacent to the pockets 8 and 13 are guide elements 15 and 16, respectively, which receive the translationally movable permanent magnets 6 and 11, respectively. Adjacent to the guide elements 15 and 16 are U-shaped iron cores 5 and 10, each carrying an electromagnet 4 and 9, respectively. The permanent magnets 6 and 11 are in the present example in moving the paper plane in and out of the paper plane. The south poles of the permanent magnets 6 and 11 are shown dotted, the north pole hatched.

Figur 2 zeigt einen Teil eines Schnitts durch den Drehsteller 1 aus Figur 1 entlang der Linie A-A. In der dargestellten oberen Position der Kugel 7 in der Tasche 8 ist die Kugel 7 in Eingriff mit einem Rastprofil 14 des beweglichen Teils 3. Eine Bewegung des beweglichen Teils 3 nach rechts wird durch die Kugel 7 blockiert. Bei einer Bewegung des beweglichen Teils 3 nach links wird die Kugel 7 nach links gedrückt und blockiert die Bewegung nicht. In einer zweiten, gestrichelt dargestellten Endposition befindet sich die Kugel 7 in der linken unteren Ecke der Tasche 8 und somit nicht im Eingriff mit dem Rastprofil 14. Der Permanentmagnet 6 ist in seiner oberen Position dargestellt. FIG. 2 shows a part of a section through the turntable 1 from FIG. 1 along the line AA. In the illustrated upper position of the ball 7 in the pocket 8, the ball 7 is in engagement with a locking profile 14 of the movable part 3. A movement of the movable part 3 to the right is blocked by the ball 7. Upon movement of the movable part 3 to the left, the ball 7 is pressed to the left and does not block the movement. In a second end position shown in dashed lines, the ball 7 is in the lower left corner of the pocket 8 and thus not engaged with the locking profile 14. The permanent magnet 6 is shown in its upper position.

Figur 3 zeigt eine Schnittdarstellung eines Teils des Drehstellers 1 aus Figur 1 entlang der Linie B-B. Der Elektromagnet 4 ist so bestromt, das sich am Ende des oberen Schenkels des Eisenkerns 5 ein schraffiert dargestellter magnetischer Nordpol und am Ende des unteren Schenkels des Eisenkerns 5 ein punktiert dargestellter magnetischer Südpol ausbildet. Der Permanentmagnet 6 liegt mit seinem dem Eisenkern 5 zugewandten Südpol an einer Lauffläche 17 des Führungselements 15 auf. Durch die magnetische Anziehung zwischen dem Nordpol im oberen Schenkel des Eisenkerns 5 und dem Südpol des Permanent-magneten 6 wird der Permanentmagnet 6 in seine in Figur 3 dargestellte Position gebracht beziehungsweise dort gehalten. Der Permanentmagnet 6 bleibt auch nach dem Abschalten des Elektromagneten 4 in dieser Position. Die magnetisierbare Kugel 7, die beispielsweise aus Stahl besteht, wird vom Permanentmagneten 6 angezogen und in ihrer in Figur 3 dargestellten Position gehalten. Dort steht die Kugel 7, wie anhand von Figur 2 erläutert, im Eingriff mit dem Rastprofil 14 des beweglichen Teils 3 und behindert somit die Drehung des beweglichen Teils 3 in eine Richtung. FIG. 3 shows a sectional view of a portion of the turntable 1 from FIG. 1 along the line BB. The electromagnet 4 is energized so that at the end of the upper leg of the iron core 5, a hatched illustrated magnetic north pole and at the end of the lower leg of the iron core 5 forms a dotted illustrated magnetic south pole. The permanent magnet 6 rests with its south pole facing the iron core 5 on a running surface 17 of the guide element 15. Due to the magnetic attraction between the north pole in the upper leg of the iron core 5 and the south pole of the permanent magnet 6 of the permanent magnet 6 is in his in FIG. 3 shown position held or held there. The permanent magnet 6 remains in this position even after switching off the electromagnet 4. The magnetizable ball 7, which consists for example of steel, is attracted by the permanent magnet 6 and in its in FIG. 3 held position held. There is the ball 7, as based on FIG. 2 explained engages with the locking profile 14 of the movable member 3 and thus hinders the rotation of the movable member 3 in one direction.

Figur 4 zeigt im Wesentlichen die Darstellung aus Figur 3, wobei der Elektromagnet 4 diesmal derart bestromt ist, dass sich am Ende des oberen Schenkels des Eisenkerns 5 ein magnetischer Südpol und am Ende des unteren Schenkels des Eisenkerns 5 ein magnetischer Nordpol ausbildet. Durch die magnetische Kraft zwischen dem Eisenkern 5 und dem Permanentmagneten 6 bewegt sich der Permanentmagnet 6 von seiner in Figur 3 dargestellten oberen Endposition in die in Figur 4 dargestellte untere Endposition. Aufgrund der magnetischen Anziehung zwischen der Kugel 7 und dem Permanentmagneten 6 folgt die Kugel 7 der Bewegung des Permanentmagneten 6 in die in Figur 4 dargestellte untere Endposition innerhalb der Tasche 8, die in Figur 2 gestrichelt dargestellt ist. In dieser Position ist die Kugel 7 nicht im Eingriff mit dem Rastprofil 14. FIG. 4 essentially shows the illustration FIG. 3 , The electromagnet 4 is energized this time so that forms at the end of the upper leg of the iron core 5, a magnetic south pole and at the end of the lower leg of the iron core 5, a magnetic north pole. Due to the magnetic force between the iron core 5 and the permanent magnet 6, the permanent magnet 6 moves from its in FIG. 3 shown upper end position in the in FIG. 4 illustrated lower end position. Due to the magnetic attraction between the ball 7 and the permanent magnet 6, the ball 7 follows the movement of the permanent magnet 6 in the in FIG. 4 illustrated lower end position within the pocket 8, the in FIG. 2 is shown in dashed lines. In this position, the ball 7 is not engaged with the locking profile 14th

Das vorstehend beschriebene Ausführungsbeispiel ist rein exemplarisch und insofern nicht beschränkend. So ist die Blockiereinrichtung bestehend aus dem Elektromagneten, dem ferromagnetischen Kern, dem Rastprofil im beweglichen Teil, dem Blockierelement und dem beweglichen Permanentmagneten nicht nur in einem Drehsteller, sondern beispielsweise auch in einem Wippschalter, einem Joystick, einer Tür, einem Zündschloss, einer Betätigungsvorrichtung oder einer sonstiger Vorrichtung verwendbar. Anstatt der in Figur 1 dargestellten zwei Blockiereinrichtungen, die jeweils eine Drehrichtung blockieren, ist eine einzelne Blockiereinrichtung möglich, die beide Drehrichtungen blockiert. Dazu rollt die Kugel nicht, wie in Figur 2 dargestellt, auf einer schrägen Ebene der Tasche, sondern geradlinig hoch beziehungsweise herunter. Selbstverständlich kann auch der Nordpol des Permanentmagneten dem Eisenkern zugewandt sein, wobei der Elektromagnet entsprechend entgegengesetzt zu bestromen ist.The embodiment described above is purely exemplary and not limiting. Thus, the blocking device consisting of the electromagnet, the ferromagnetic core, the locking profile in the moving part, the blocking element and the movable permanent magnet not only in a turntable, but for example, in a rocker switch, a joystick, a door, an ignition, an actuator or another device used. Instead of in FIG. 1 shown two blocking devices, each blocking a direction of rotation, a single blocking device is possible, which blocks both directions of rotation. To do this, the ball does not roll, as in FIG. 2 shown, on a sloping plane of the bag, but straight up or down. Of course, the north pole of the permanent magnet may also face the iron core, wherein the electromagnet is to be energized correspondingly opposite.
