Definitions

  • the invention relates to an electromechanical locking device consisting of a cylinder lock with a device for transmitting information signals between the lock and key, a stator housing with a rotatable rotor in this housing and a locking device for preventing rotary movements of the rotor in the stator housing and a key. It is known to additionally combine cylinder locks with mechanically coded tumblers with an electromagnetic locking device, and thereby to increase the security of the locking device. In the case of bank and vault devices in particular, the electromagnetic locks act directly on the locking bolts, whereby they can mostly be actuated by an electrical or electronic control arranged independently of the mechanical key. Such systems are complex and require a relatively large amount of installation space.
  • Such a locking device is known from German Offenlegungsschrift No. 3 205 586.
  • the key carries information in the form of magnetic codes.
  • a corresponding reading device is arranged on the cylinder lock, which reads from the Key impulses given code impulses and forwarded to a recognition device.
  • This electronic detection device is connected to an electromagnetic actuation device, which can connect the rotor to the bolt actuation element in a rotationally locking manner via a driver pin.
  • This bolt actuator is arranged at right angles to the lock axis and protrudes from the lock cylinder. Stable and relatively strong magnets are required to generate the necessary forces and movement lengths of the driver pin, which means that the external dimensions of the cylinder lock become significantly larger than those of the locks normally used.
  • the electromagnet can be excited by an electrical control and that locking part sitting at the end of the armature can be brought into a position in which the link ring is released for a rotary movement.
  • the solution shown here requires an extension of the cylinder lock in the axial direction, which is undesirable in many cases.
  • the design of double cylinder locks in which two mechanical cylinders are combined with one another in the axial direction is only possible with considerable effort.
  • the axial dimensions of the lock must be changed compared to the known mechanical cylinder locks, which in turn leads to difficulties when replacing locks in existing doors and the like.
  • the locking device has a trigger bolt directed radially to the rotor axis and a locking bolt arranged parallel to this trigger bolt, also oriented approximately at right angles to the rotor axis, and one end face of the trigger bolt rests on the sliding surface of a tumbler pin positioned by the key in the rotor, the trigger bolt engages in the locking bolt via a driver, approximately at right angles to the release and locking bolts and in the areas facing away from the rotor, an electrical switching element consisting of a magnet armature with an electric coil is arranged, and the magnet armature has at least one locking device in which the locking bolt engages.
  • This inventive arrangement makes it possible to arrange the magnet armature with the electrocoil parallel to the cylinder lock axis, and thereby keeping the outer dimensions of the lock small.
  • the release and locking bolts arranged at right angles to the lock axis are operatively connected to the magnetic armature.
  • the release pin does not engage the rotor directly, but in turn interacts with a tumbler pin, which is brought into the correct position by the key inserted in the lock. Only if the mechanical coding on the key matches this release bolt can the locking bolt be released by the magnet armature, and thus the rotary movement of the rotor in the stator housing can be released.
  • This arrangement enables additional security against unauthorized intervention in the locking device, which is very important in the case of combined electromechanical locks.
  • the arrangement made also effectively prevents unauthorized intervention in the locking device by means acting on the lock from the outside. Furthermore, the space in the direction of the longitudinal axis of the cylinder lock is not claimed by the locking device, as a result of which the known mechanical rotor / stator arrangements can be used and double cylinder locks can also be combined in the known manner.
  • the operative connection between the key / lock rotor and the lock / bolt is also established in the known manner, and no additional measures are required to ensure its security and effectiveness.
  • the magnetic armature is controlled via the electrocoil by an external control or an electronic device integrated in the lock. It is obvious to the person skilled in the art that equivalent solutions are possible in which the magnet armature is extended or retracted by the magnet, or is pushed or pulled by the magnetic force.
  • a preferred embodiment of the invention is characterized in that the release pin is fork-shaped at one end, the two legs of the fork-shaped part delimit a gap, and the magnet armature is guided in this gap.
  • This arrangement enables a very compact design, the magnet armature being as small as possible Distance to the lock axis is arranged.
  • a further improvement in the construction can be achieved in that the legs extend beyond the magnet armature, form a second intermediate space, and a compression spring is arranged in this intermediate space in such a way that it presses the release bolt in the direction of the rotor.
  • a further preferred embodiment of the invention consists in that a resilient return element acting in the direction of movement of the armature is arranged on the magnet armature.
  • This return element causes the armature and the release bolt to be returned to the locked position.
  • the resilient restoring element is designed like a lever and is provided with a fulcrum, one lever arm of the element rests on a driver of the release bolt and the other lever arm of the element rests on a driver on the magnet armature.
  • This arrangement means that the release pin and the magnet armature, despite moving at right angles to one another, are inevitably connected to one another.
  • the restoring element is used in particular to return the magnet armature to its starting position when the magnet coil is de-energized.
  • the locking pin has a driver shoulder, a compression spring rests on the end face of the locking pin directed against the rotor, and the driver of the trigger pin on the driver shoulder.
  • This arrangement ensures a play-free guidance of the locking bolt, which is always in operative connection with the release bolt. Since the two bolts are arranged in parallel next to each other, it is possible to bring the release bolt into operative connection with a tumbler pin in the rotor.
  • the locking pin acts as a rotor lock in that an annular groove is arranged on the outer jacket of the rotor, this groove lies in the axis of the locking pin and extends on both sides of the normal position of the locking pin over a maximum of 90 ° of the circumference of the rotor.
  • the rotor can be rotated by a certain amount when the mechanical tumblers between the lock and key match, in order to ensure the reading process between the lock and key. There is also enough time to withdraw the locking pin from the rotor before it is clamped by the groove wall, thereby requiring a short backward movement to release the locking pin driven by a spring.
  • a further improvement in the possibilities of engagement of the locking bolt in the magnet armature can be achieved in that the locking device on the magnet armature is formed by a depression and the lower end of the locking bolt is shaped corresponding to this depression.
  • a preferred embodiment of the invention further consists in that a groove with a pin is formed on the magnet armature in the switching direction in front of the recess and a shoulder is present on the lower end face of the locking bolt, which cooperates with the pin.
  • This groove forms only a slight depression on the jacket of the magnet armature.
  • the interaction between the shoulder on the end face of the locking bolt and the pin on the magnet armature holds the magnet armature in its starting position. It is therefore not possible to bring the magnetic armature into its switching position by vibrating or other external influences on the lock and thereby withdrawing the locking pin from the rotor. This is only possible if the electromagnet is activated and the magnet armature is attracted by direct force in the direction of the lock axis.
  • the shoulder on the end face of the locking bolt jumps over the pin of the groove on the magnet armature and snaps into the recess of the magnet armature, which acts as a lock, a.
  • a further increase in the security of the locking device can be achieved in that a microswitch is installed in the electrical supply line to the electrocoil and this microswitch has a switching pin as the switching element, the end of which protrudes into the key channel on the rotor.
  • the microswitch comprises a membrane keyboard and this is integrated in the circuit board. In addition to the correct actuation of the release pin via the associated tumbler pin, the microswitch must also be actuated by the key to release the lock. Otherwise the electrical control device remains without power and the locking device is not released.
  • a membrane keyboard such as is used for example in control consoles, enables a further reduction in the structural dimensions and the integration of the switch in the rotor / stator area of a known cylinder lock. Since only one switching element is required, a single membrane key can be integrated into the circuit board, which is built into the stator housing of the lock and carries the required electronic components. All essential electronic components can be directly connected to each other on the circuit board.

Despite the small dimensions, it has additional security features, which represent significant improvements to the known locking devices.

The rotor can thus only be rotated to the extent that a corresponding groove 38 is arranged on the circumference. If the electronic coding of the key 2 does not match the lock 1, the rotor 5 cannot be rotated completely even if the mechanical tumblers match, and thus the lock cannot be opened. If the electronic coding of the key 2 matches that of the cylinder lock 1, the electronic control 11 is activated by the electronic control and the magnet armature 12 is drawn into the core bore 50 during the rotary movement of the rotor 5 with the aid of the key 2 in the region of the ring groove 38 .
  • the shoulder 41 on the locking pin 14 jumps over the pin 36 and the lower end 40 engages in the recess 34. Since the spring 42 presses the locking pin 14 against the magnet armature 12, the power supply to the electrocoil 11 can be interrupted immediately, as a result of which the power consumption of this device is extremely low. If the key 2 is removed again from the cylinder lock 1, the microswitch 56 also interrupts the control current to the other electrical and electronic components, which leads to a significantly increased electrical safety and service life of the power sources.

PCT No. PCT/CH88/00025 Sec. 371 Date Oct. 4, 1988 Sec. 102(e) Date Oct. 4, 1988 PCT Filed Feb. 2, 1988 PCT Pub. No. WO88/05853 PCT Pub. Date Aug. 11, 1988.An electromechanical cylinder lock (1) is connected with a key (2 l) which has electronic and mechanical codings. In the lock (1) are arranged and connected with each other electronic elements (55), a microswitch (56) and an electric coil (11) with a magnet anchor (12). The magnet anchor (12) is part of the blocking device (6) which, through a release bolt (13) and a holding pin (15), engages in the rotor (5) of the lock (1). Parallel with the release bolt (13) is arranged a blocking bolt (14) which engages, at one end, in the rotor (5), and at the other end, in the magnet anchor (12). For the opening of the lock, besides the mechanical blocking elements, the microswitch (56), the release bolt (13), the magnet anchor (12) and the blocking bolt (14) must also be brought into their correct positions.

Description

Die Erfindung betrifft eine elektromechanische Schliesseinrichtung bestehend aus einem Zylinderschloss mit einer Einrichtung zum Uebertragen von Informationssignalen zwischen Schloss und Schlüssel, einem Statorgehäuse mit in diesem Gehäuse drehbarem Rotor und einer Sperreinrichtung zur Verhinderung von Drehbewegungen des Rotors im Statorgehäuse und einem Schlüssel. Es ist bekannt, Zylinderschlösser mit mechanisch kodierten Zuhaltungen zusätzlich mit einer elektromagnetisch sperrenden Einrichtung zu kombinieren, und dadurch die Sicherheit der Schliesseinrichtung zu erhöhen. Insbesondere bei Bank- und Tresoreinrichtungen wirken dabei die elektromagnetischen Sperren direkt auf die Schliessriegel, wobei sie zumeist durch eine unabhängig vom mechanischen Schlüssel angeordnete elektrische oder elektronische Steuerung betätigt werden können. Derartige Systeme sind aufwendig und benötigen relativ viel Einbauraum. Im weiteren wurden Einrichtungen entwickelt, bei welchen die Inforrmationsgeber direkt auf dem mechanischen Schlüssel angebracht, und im Zylinderschloss entsprechende Leseeinrichtungen zur Erkennung der Informationssignale eingebaut wurden. Mittels des Schlüssels ist ein im Innern des Zylinderschlosses angeordneter Rotor drehbar, und der Schliessriegel wird durch diese Drehbewegung betätigt.The invention relates to an electromechanical locking device consisting of a cylinder lock with a device for transmitting information signals between the lock and key, a stator housing with a rotatable rotor in this housing and a locking device for preventing rotary movements of the rotor in the stator housing and a key. It is known to additionally combine cylinder locks with mechanically coded tumblers with an electromagnetic locking device, and thereby to increase the security of the locking device. In the case of bank and vault devices in particular, the electromagnetic locks act directly on the locking bolts, whereby they can mostly be actuated by an electrical or electronic control arranged independently of the mechanical key. Such systems are complex and require a relatively large amount of installation space. Furthermore, devices were developed in which the information transmitters were attached directly to the mechanical key, and corresponding reading devices for recognizing the information signals were installed in the cylinder lock. By means of the key, a rotor arranged in the interior of the cylinder lock can be rotated, and the locking bolt is actuated by this rotary movement.

Eine derartige Schliesseinrichtung ist aus der Deutschen Offenlegungsschrift Nr. 3 205 586 bekannt. Bei dieser Schliesseinrichtung trägt der Schlüssel Informationen in der Form von magnetischen Kodierungen. Am Zylinderschloss ist eine entsprechende Leseeinrichtung angeordnet, welche die vom Schlüssel abgegebenen Kode-Impulse übernimmt und an eine Erkennungseinrichtung weiterleitet. Diese elektronische Erkennungseinrichtung ist mit einer elektromagnetischen Betätigungseinrichtung verbunden, welche über einen Mitnehmerstift den Rotor drehschlüssig mit dem Riegelbetätigungsorgan verbinden kann. Dieses Riegelbetätigungsorgan ist rechtwinklig zur Schlossachse angeordnet und ragt aus dem Schlosszylinder heraus. Zur Erzeugung der notwendigen Kräfte und Bewegungslängen des Mitnehmerstiftes sind stabile und relativ kräftige Magnete notwendig, wodurch die Aussenabmessungen des Zylinderschlosses wesentlich grösser werden als diejenigen der normal verwendeten Schlösser. Es ist deshalb nicht möglich, derartige Schliesseinrichtungen in bereits vorhandene Türen oder Einrichtungen einzusetzen, ohne diese umzubauen oder grundsätzliche Aenderungen vorzunehmen. Bei dieser bekannten Vorrichtung werden die Informationssignale durch Drehen des Schlüssels übertragen und anschliessend, wenn die Informationen mit der im Schloss vorgegebenen Impulsfolge übereinstimmen, der Rotor mit der Riegelbetätigungsvorrichtung gekoppelt. Diese Ausführung entspricht ebenfalls nicht den häufig verwendeten heute bekannten mechanischen Zylinderschlössern, und es ist nicht erkennbar, wie dieses Prinzip auf diese übertragen werden könnte.Such a locking device is known from German Offenlegungsschrift No. 3 205 586. With this locking device, the key carries information in the form of magnetic codes. A corresponding reading device is arranged on the cylinder lock, which reads from the Key impulses given code impulses and forwarded to a recognition device. This electronic detection device is connected to an electromagnetic actuation device, which can connect the rotor to the bolt actuation element in a rotationally locking manner via a driver pin. This bolt actuator is arranged at right angles to the lock axis and protrudes from the lock cylinder. Stable and relatively strong magnets are required to generate the necessary forces and movement lengths of the driver pin, which means that the external dimensions of the cylinder lock become significantly larger than those of the locks normally used. It is therefore not possible to use locking devices of this type in existing doors or facilities without converting them or making fundamental changes. In this known device, the information signals are transmitted by turning the key and then, if the information matches the pulse sequence specified in the lock, the rotor is coupled to the bolt actuation device. This version also does not correspond to the frequently used mechanical cylinder locks known today, and it is not clear how this principle could be applied to them.

Die Probleme der rechtwinklig zur Zylinderschlossachse angeordneten Elektromagnete und Betätigungsstifte wurden bereits früher erkannt, und eine andere Lösung zeigt die Europäische Patentanmeldung Publikation Nr. 110 835. Bei diesem, mit einem mechanischen Wendeflachschlüssel betätigten, Zylinderschloss ist am Aussenmantel, ein Elektromagnet mit einem Magnetanker angeordnet, welcher parallel zur Schlossachse verläuft. Der Magnetanker ist an seinem freien Ende mit Zusatzeinrichtungen versehen, welche in einen Kulissenring eingreifen. Dieser Kulissenring ist auf einer Verlängerung am hinteren Ende des Rotors befestigt und wird mit diesem verdreht. Mittels einer elektrischen Steuerung kann der Elektromagnet angeregt und das am Ende des Ankers sitzende Sperrteil in eine Position gebracht werden, in welcher der Kulissenring für eine Drehbewegung freigegeben wird. Die hier dargestellte Lösung erfordert eine Verlängerung des Zylinderschlosses in axialer Richtung, was in vielen Fällen unerwünscht ist. Im weiteren ist die Ausführung von Doppelzylinderschlössern, bei welchen zwei mechanische Zylinder in Achsrichtung miteinander kombiniert werden nur mit erheblichem Aufwand möglich. Die axialen Abmessungen des Schlosses müssen gegenüber den bekannten mechanischen Zylinderschlössern verändert werden, was wiederum zu Schwierigkeiten beim Austausch von Schlössern in bestehenden Türen und dergleichen führt.The problems of the electromagnets and actuating pins arranged at right angles to the cylinder lock axis have already been recognized, and another solution is shown in European patent application publication no. 110 835. In this cylinder lock, which is actuated with a mechanical reversible flat key, an electromagnet with a magnet armature is arranged on the outer casing. which runs parallel to the lock axis. At its free end, the magnet armature is provided with additional devices which engage in a link ring. This sliding ring is attached to an extension at the rear end of the rotor and is rotated with it. The electromagnet can be excited by an electrical control and that locking part sitting at the end of the armature can be brought into a position in which the link ring is released for a rotary movement. The solution shown here requires an extension of the cylinder lock in the axial direction, which is undesirable in many cases. Furthermore, the design of double cylinder locks in which two mechanical cylinders are combined with one another in the axial direction is only possible with considerable effort. The axial dimensions of the lock must be changed compared to the known mechanical cylinder locks, which in turn leads to difficulties when replacing locks in existing doors and the like.

Es ist Aufgabe der vorliegenden Erfindung, eine elektromechanische Schliesseinrichtung zu schaffen, bei welcher ein Zylinderschloss der bekannten Art mit mechanischen Zuhaltungen einsetzbar ist, der Elektromagnet etwa parallel zur Schlossachse angeordnet und der Sperrstift rechtwinklig zur Schlossachse in den Rotor eingreift. Im weiteren soll die Sperreinrichtung mit der mechanischen Kodierung des Schlüssels kombiniert und für die Betätigung der Magnetspule nur ein Stromimpuls und keine Daueraktivierung notwendig sein.It is an object of the present invention to provide an electromechanical locking device in which a cylinder lock of the known type with mechanical tumblers can be used, the electromagnet is arranged approximately parallel to the lock axis and the locking pin engages in the rotor at right angles to the lock axis. Furthermore, the locking device should be combined with the mechanical coding of the key and only a current pulse and no permanent activation should be necessary to actuate the magnetic coil.

Diese Aufgabe wird dadurch gelöst, dass die Sperreinrichtung einen radial zur Rotorachse gerichteten Auslösebolzen und einen parallel neben diesem Auslösebolzen angeordneten, ebenfalls etwa rechtwinklig zur Rotorachse gerichteten Sperrbolzen aufweist, eine Endfläche des Auslösebolzens an der Gleitfläche eines vom Schlüssel positionierten Zuhaltungsstiftes im Rotor anliegt, der Auslösebolzen über einen Mitnehmer in den Sperrbolzen eingreift, etwa rechtwinklig zu den Auslöse- und Sperrbolzen und in deren vom Rotor abgewendeten Bereiche ein elektrisches Schaltelement bestehend aus einem Magnetanker mit einer Elektrospule angeordnet ist, und der Magnetanker mindestens eine Arretierung aufweist, in welche der Sperrbolzen eingreift. Diese erfinderische Anordnung ermöglicht es, den Magnetanker mit der Elektrospule parallel zur Zylinderschlossachse anzuordnen, und dadurch die äusseren Abmessungen des Schlosses klein zu halten. Die rechtwinklig zur Schlossachse angeordneten Auslöse- und Sperrbolzen stehen mit dem Magnetanker in Wirkverbindung. Der Auslösebolzen greift nicht direkt in den Rotor ein, sondern wirkt seinerseits mit einem Zuhaltungsstift zusammen, welcher vom in das Schloss eingesteckten Schlüssel in die richtige Position gebracht wird. Nur bei Uebereinstimmen der mechanischen Kodierung auf dem Schlüssel mit diesem Auslösebolzen kann der Sperrbolzen durch den Magnetanker gelöst, und damit die Drehbewegung des Rotors im Statorgehäuse freigegeben werden. Diese Anordnung ermöglicht eine zusätzliche Sicherung gegen unbefugtes Eingreifen in die Schliesseinrichtung, was bei kombinierten elektromechanischen Schlössern sehr wichtig ist. Die getroffene Anordnung verhindert im weitern in wirksamer Weise den unbefugten Eingriff in die Sperreinrichtung durch von aussen auf das Schloss einwirkende Mittel. Im weitern wird der Raum in Richtung der Längsachse des Zylinderschlosses durch die Sperreinrichtung nicht beansprucht, wodurch die bekannten mechanischen Rotor-/Statoranordnungen einsetzbar sind und auch Doppelzylinderschlösser in der bekannten Weise kombiniert werden können. Auch die Wirkverbindung zwischen Schlüssel/sShlossrotor und Schloss/Riegel wird in der bekannten Weise hergestellt, und es bedarf keiner zusätzlichen Massnahmen, um deren Sicherheit und Wirksamkeit zu gewährleisten. Die Ansteuerung des Magnetankers über die Elektrospule erfolgt von einer externen Steuerung oder einer in das Schloss integrierten elektronischen Einrichtung. Für den Fachmann ist offensichtlich, dass gleichwertige Lösungen möglich sind, bei welchen der Magnetanker durch den Magneten ausgefahren oder eingezogen, bzw. durch die Magnetkraft gestossen oder gezogen wird.This object is achieved in that the locking device has a trigger bolt directed radially to the rotor axis and a locking bolt arranged parallel to this trigger bolt, also oriented approximately at right angles to the rotor axis, and one end face of the trigger bolt rests on the sliding surface of a tumbler pin positioned by the key in the rotor, the trigger bolt engages in the locking bolt via a driver, approximately at right angles to the release and locking bolts and in the areas facing away from the rotor, an electrical switching element consisting of a magnet armature with an electric coil is arranged, and the magnet armature has at least one locking device in which the locking bolt engages. This inventive arrangement makes it possible to arrange the magnet armature with the electrocoil parallel to the cylinder lock axis, and thereby keeping the outer dimensions of the lock small. The release and locking bolts arranged at right angles to the lock axis are operatively connected to the magnetic armature. The release pin does not engage the rotor directly, but in turn interacts with a tumbler pin, which is brought into the correct position by the key inserted in the lock. Only if the mechanical coding on the key matches this release bolt can the locking bolt be released by the magnet armature, and thus the rotary movement of the rotor in the stator housing can be released. This arrangement enables additional security against unauthorized intervention in the locking device, which is very important in the case of combined electromechanical locks. The arrangement made also effectively prevents unauthorized intervention in the locking device by means acting on the lock from the outside. Furthermore, the space in the direction of the longitudinal axis of the cylinder lock is not claimed by the locking device, as a result of which the known mechanical rotor / stator arrangements can be used and double cylinder locks can also be combined in the known manner. The operative connection between the key / lock rotor and the lock / bolt is also established in the known manner, and no additional measures are required to ensure its security and effectiveness. The magnetic armature is controlled via the electrocoil by an external control or an electronic device integrated in the lock. It is obvious to the person skilled in the art that equivalent solutions are possible in which the magnet armature is extended or retracted by the magnet, or is pushed or pulled by the magnetic force.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass der Auslöselbolzen an einem Ende gabelförmig ausgebildet ist, die beiden Schenkel des gabelförmigen Teiles einen Zwischenraum begrenzen, und der Magnetanker in diesem Zwischenraum geführt ist. Diese Anordnung ermöglicht eine sehr kompakte Bauweise, wobei der Magnetanker mit möglichst geringem Abstand zur Schlossachse angeordnet ist. Eine weitere Verbesserung der Konstruktion lässt sich dadurch erreichen, dass sich die Schenkel über den Magnetanker hinaus erstrecken, einen zweiten Zwischenraum bilden, und in diesem Zwischenraum eine Druckfeder so angeordnet ist, dass sie den Auslösebolzen in Richtung des Rotors drückt.A preferred embodiment of the invention is characterized in that the release pin is fork-shaped at one end, the two legs of the fork-shaped part delimit a gap, and the magnet armature is guided in this gap. This arrangement enables a very compact design, the magnet armature being as small as possible Distance to the lock axis is arranged. A further improvement in the construction can be achieved in that the legs extend beyond the magnet armature, form a second intermediate space, and a compression spring is arranged in this intermediate space in such a way that it presses the release bolt in the direction of the rotor.

Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass am Magnetanker ein in der Bewegungsrichtung des Ankers wirkendes federndes Rückstellelement angeordnet ist. Dieses Rückstellelement bewirkt jeweils die Rückführung des Ankers und des Auslösebolzens in die Sperrstellung. In weiterer Ausgestaltung der Erfindung ist das federnde Rückstellelement hebelartig ausgebildet und mit einem Drehpunkt versehen, ein Hebelarm des Elementes liegt an einem Mitnehmer des Auslösebolzens und der andere Hebelarm des Elementes an einem Mitnehmer am Magnetanker auf. Diese Anordnung bewirkt, dass Auslösebolzen und Magnetanker, trotzdem sie sich rechtwinklig zueinander bewegen, zwangsläufig miteinander verbunden sind. Das Rückstellelement dient insbesondere der Rückführung des Magnetankers in seine Ausgangsposition bei stromloser Magnetspule.A further preferred embodiment of the invention consists in that a resilient return element acting in the direction of movement of the armature is arranged on the magnet armature. This return element causes the armature and the release bolt to be returned to the locked position. In a further embodiment of the invention, the resilient restoring element is designed like a lever and is provided with a fulcrum, one lever arm of the element rests on a driver of the release bolt and the other lever arm of the element rests on a driver on the magnet armature. This arrangement means that the release pin and the magnet armature, despite moving at right angles to one another, are inevitably connected to one another. The restoring element is used in particular to return the magnet armature to its starting position when the magnet coil is de-energized.

In weiterer Ausgestaltung der Erfindung weist der Sperrbolzen eine Mitnehmerschulter auf, an der gegen den Rotor gerichteten Stirnseite des Sperrbolzens liegt eine Druckfeder und an der Mitnehmerschulter der Mitnehmer des Auslösebolzens an. Diese Anordnung gewährleistet eine spielfreie Führung des Sperrbolzens, wobei dieser immer in Wirkverbindung mit dem Auslösebolzen steht. Da die beiden Bolzen parallel nebeneinander angeordnet sind, ist es möglich, den Auslösebolzen mit einem Zuhaltungsstift im Rotor in Wirkverbindung zu bringen. Der Sperrbolzen wirkt als Rotorsperre, indem am Aussenmantel des Rotors eine Ringnut angeordnet ist, diese Nut in der Achse des Sperrbolzens liegt und sich beidseits der Normalposition des Sperrbolzens über je maximal 90° des Umfanges des Rotors erstreckt. Insbesondere bei im Schloss integrierten Lese- und Kodiereinrichtungen ist es zweckmässig, wenn der Rotor bei Uebereinstimmung der mechanischen Zuhaltungen zwischen Schloss und Schlüssel um ein bestimmtes Mass gedreht werden kann, um den Lesevorgang zwischen Schloss und Schlüssel zu gewährleisten. Es steht damit auch genügend Zeit zur Verfügung, um den Sperrbolzen aus dem Rotor zurückzuziehen, bevor er durch die Nutwandung festgeklemmt, und dadurch eine kurze Rückwärtsbewegung zur Freigabe des durch eine Feder angetriebenen Sperrbolzens notwendig wird.In a further embodiment of the invention, the locking pin has a driver shoulder, a compression spring rests on the end face of the locking pin directed against the rotor, and the driver of the trigger pin on the driver shoulder. This arrangement ensures a play-free guidance of the locking bolt, which is always in operative connection with the release bolt. Since the two bolts are arranged in parallel next to each other, it is possible to bring the release bolt into operative connection with a tumbler pin in the rotor. The locking pin acts as a rotor lock in that an annular groove is arranged on the outer jacket of the rotor, this groove lies in the axis of the locking pin and extends on both sides of the normal position of the locking pin over a maximum of 90 ° of the circumference of the rotor. Especially when reading and integrated in the lock Coding devices are expedient if the rotor can be rotated by a certain amount when the mechanical tumblers between the lock and key match, in order to ensure the reading process between the lock and key. There is also enough time to withdraw the locking pin from the rotor before it is clamped by the groove wall, thereby requiring a short backward movement to release the locking pin driven by a spring.

Eine weitere Verbesserung der Eingriffsmöglichkeiten des Sperrbolzens in den Magnetanker lässt sich dadurch erreichen, dass die Arretierung am Magnetanker durch eine Vertiefung gebildet ist, und das untere Ende des Sperrbolzens entsprechend dieser Vertiefung geformt ist. Eine bevorzugte Ausführungsform der Erfindung besteht im weiteren darin, dass am Magnetanker in Schaltrichtung vor der Vertiefung eine Nute mit einem Zapfen ausgebildet und an der unteren Stirnfläche des Sperrbolzens eine Schulter vorhanden ist, welche mit dem Zapfen zusammenwirkt. Bei eingestecktem und richtig kodiertem mechanischem Schlüssel gibt der Auslösebolzen die Bewegung des Sperrbolzens frei. Der Sperrbolzen wird von einer Feder gegen den Magnetanker gedrückt, wobei die Schulter an der Stirnfläche des Sperrbolzens in die Vertiefung, bzw. den Zapfen der Nute am Magnetanker eingreift. Diese Nute bildet nur eine geringfügige Vertiefung am Mantel des Magnetankers. Das Zusammenwirken zwischen der Schulter an der Stirnfläche des Sperrbolzens und dem Zapfen am Magnetanker hält den Magnetanker in seiner Ausgangsposition fest. Es ist deshalb nicht möglich, den Magnetanker durch Vibrieren oder anderweitige äussere Einwirkungen auf das Schloss in seine Schaltposition zu bringen und dadurch den Sperrbolzen aus dem Rotor zurückzuziehen. Dies ist nur möglich, wenn der Elektromagnet aktiviert und damit der Magnetanker durch direkte Krafteinwirkung in Richtung der Schlossachse angezogen wird. Dabei überspringt die Schulter an der Stirnfläche des Sperrbolzens den Zapfen der Nute am Magnetanker und rastet in die Vertiefung des Magnetankers, welche als Arretierung wirkt, ein. Auch bei stromloser Magnetspule wird jetzt der Magnetanker in seiner Schaltposition gehalten, und der Sperrbolzen bleibt aufgrund der Federwirkung ausserhalb des Drehbereiches des Rotors. Die Aktivierung der Magnetspule erfolgt jedoch nur, wenn die vom Schlüssel an das Schloss übertragenen Informationssignale richtig waren, und damit die elektrische Steuereinrichtung das Schloss zur Betätigung freigibt.A further improvement in the possibilities of engagement of the locking bolt in the magnet armature can be achieved in that the locking device on the magnet armature is formed by a depression and the lower end of the locking bolt is shaped corresponding to this depression. A preferred embodiment of the invention further consists in that a groove with a pin is formed on the magnet armature in the switching direction in front of the recess and a shoulder is present on the lower end face of the locking bolt, which cooperates with the pin. When the mechanical key is inserted and correctly coded, the release bolt releases the movement of the locking bolt. The locking pin is pressed against the magnet armature by a spring, the shoulder on the end face of the locking pin engaging in the recess or the pin of the groove on the magnet armature. This groove forms only a slight depression on the jacket of the magnet armature. The interaction between the shoulder on the end face of the locking bolt and the pin on the magnet armature holds the magnet armature in its starting position. It is therefore not possible to bring the magnetic armature into its switching position by vibrating or other external influences on the lock and thereby withdrawing the locking pin from the rotor. This is only possible if the electromagnet is activated and the magnet armature is attracted by direct force in the direction of the lock axis. The shoulder on the end face of the locking bolt jumps over the pin of the groove on the magnet armature and snaps into the recess of the magnet armature, which acts as a lock, a. Even when the solenoid is de-energized, the magnet armature is now held in its switching position, and the locking bolt remains outside the rotating range of the rotor due to the spring action. However, the solenoid is only activated if the information signals transmitted from the key to the lock were correct, and thus the electrical control device releases the lock for actuation.

Eine weitere Steigerung der Sicherheit der Schliesseinrichtung lässt sich dadurch erreichen, dass in der elektrischen Zuleitung zur Elektrospule ein Mikroschalter eingebaut ist, und dieser Mikroschalter als Schaltelement einen Schaltstift aufweist, dessen Ende in den Schlüsselkanal am Rotor ragt. In weiterer Ausgestaltung der Erfindung umfasst der Mikroschalter eine Folientastatur und diese ist in die Leiterplatte integriert. Zusätzlich zur richtigen Betätigung des Auslösebolzens über den zugehörigen Zuhaltungsstift muss zur Freigabe des Schlosses auch der Mikroschalter durch den Schlüssel betätigt werden. Andernfalls bleibt die elektrische Steuereinrichtung ohne Strom, und die Sperreinrichtung wird nicht freigegeben. Die Verwendung einer Folientastatur, wie sie zum Beispiel bei Steuerkonsolen Verwendung findet, ermöglicht eine weitere Reduktion der Bauabmessungen und die Integration des Schalters in den Rotor­/Statorbereich eines bekannten Zylinderschlosses. Da nur ein Schaltelement benötigt wird, lässt sich eine einzelne Folientaste in die Leiterplatte integrieren, welche in das Statorgehäuse des Schlosses eingebaut ist und die benötigten elektronischen Bauelemente trägt. Auf der Leiterplatte lassen sich alle wesentlichen elektronischen Bauelemente direkt miteinander verbinden.A further increase in the security of the locking device can be achieved in that a microswitch is installed in the electrical supply line to the electrocoil and this microswitch has a switching pin as the switching element, the end of which protrudes into the key channel on the rotor. In a further embodiment of the invention, the microswitch comprises a membrane keyboard and this is integrated in the circuit board. In addition to the correct actuation of the release pin via the associated tumbler pin, the microswitch must also be actuated by the key to release the lock. Otherwise the electrical control device remains without power and the locking device is not released. The use of a membrane keyboard, such as is used for example in control consoles, enables a further reduction in the structural dimensions and the integration of the switch in the rotor / stator area of a known cylinder lock. Since only one switching element is required, a single membrane key can be integrated into the circuit board, which is built into the stator housing of the lock and carries the required electronic components. All essential electronic components can be directly connected to each other on the circuit board.

Die erfindungsgemässe elektromechanische Schliesseinrichtung weist sehr geringe Bauabmessungen auf, ohne den gewünschten hohen Sicherheitsstandard derartiger Schliesseinrichtungen einzuschränken. Trotz der geringen Bauabmessungen weist sie zusätzliche Sicherheitsmerkmale auf, welche erhebliche Verbesserungen der bekannten Schliesseinrichtungen darstellen.The electromechanical locking device according to the invention has very small dimensions without restricting the desired high security standard of such locking devices. Despite the small dimensions, it has additional security features, which represent significant improvements to the known locking devices.

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 ein Zylinderschloss mit elektronischen und mechanischen Kodierungen und einer Sperreinrichtung im Längsschnitt,
  • Fig. 2 einen vergrösserten Teilausschnitt aus einem Querschnitt durch das Schloss gemäss Figur 1 im Bereiche des Auslösebolzens,
  • Fig. 3 den Magnetanker in perspektivischer Ansicht und vergrösserter Darstellung.
The invention is explained in more detail below on the basis of exemplary embodiments with reference to the accompanying drawings. Show it:
  • 1 is a cylinder lock with electronic and mechanical coding and a locking device in longitudinal section,
  • 2 shows an enlarged partial section from a cross section through the lock according to FIG. 1 in the region of the release bolt,
  • Fig. 3 shows the magnetic armature in a perspective view and an enlarged view.

Das in Figur 1 dargestellte Zylinderschloss 1 enthält sowohl mechanische wie auch elektronische Kodierungen mit entsprechenden Zuhaltungen. In das Zylinderschloss 1 ist ein Schlüssel 2 eingesteckt, welcher einen Schlüsselbart 8, einen Kontaktbereich 7 und eine Reide 9 umfasst. An den Breitseiten des Schlüsselbartes 8 sind Nuten 46, 47 angeordnet, welche mit den nicht dargestellten mechanischen Zuhaltungen zusammenwirken. Diese nicht dargestellten Zuhaltungen sind in einem Rotor 5 gelagert, welcher seinerseits in einem Stator 3 drehbar ist. Im Rotor 5 ist auch ein Schlüsselkanal 48 angeordnet, in welchem der Schlüsselbart 8 geführt ist. Um den Stator 3 ist ein zusätzliches Statorgehäuse 4 vorgesehen, welches die Sperreinrichtung 6 und die Kontakteinrichtung 51 mit den entsprechenden elektrischen und elektronischen Verbindungen und Bauelementen aufnimmt. Das ganze Zylinderschloss 1 ist von einem Aussenmantel 25 umgeben.The cylinder lock 1 shown in Figure 1 contains both mechanical and electronic codes with corresponding tumblers. A key 2 is inserted into the cylinder lock 1 and comprises a key bit 8, a contact area 7 and a cover 9. Grooves 46, 47 are arranged on the broad sides of the key bit 8, which cooperate with the mechanical tumblers, not shown. These tumblers, not shown, are mounted in a rotor 5, which in turn is rotatable in a stator 3. A key channel 48 is also arranged in the rotor 5, in which the key bit 8 is guided. An additional stator housing 4 is provided around the stator 3, which accommodates the locking device 6 and the contact device 51 with the corresponding electrical and electronic connections and components. The entire cylinder lock 1 is surrounded by an outer jacket 25.

In der Reide 9 des Schlüssels 2 sind nicht dargestellte elektronische Elemente, wie zum Beispiel Datenspeicher, angeordnet, welche mit Kontaktstellen 54 im Kontaktbereich 7 des Schlüssels 2 verbunden sind. Diese Kontaktstellen 54 befinden sich an den Schmalseiten des Schlüssels 2 und wirken mit Schleiffedern 53 zusammen. Die Schleiffedern 53 sind an einer Leiterplatte 52 befestigt und stehen über elektrische Leiter mit elektronischen Elementen 55, welche auf der Leiterplatte 52 und/oder extern angeordnet sind, in Verbindung. In die Leiterplatte 52 ist eine Folientaste 57 integriert, welche Teil eines Mikroschalters 56 ist. Dieser Mikroschalter 56 ragt in den Schlüsselkanal 48 und weist in seinem Innern nicht dargestellte federnde Elemente auf. Der Mikroschalter 56 kann direkt durch die Schmalseite des Schlüsselbartes 8 oder, wie in Figur 1 dargestellt, mittels einer zusätzlichen Kodierung am Schlüssel 2 betätigt werden. Bei in das Zylinderschloss 1 eingestecktem Schlüssel 2 wirkt der Mikroschalter 56 auf die Folientaste 57 ein und schaltet den Stromkreislauf für die elektronische Kodierung, bzw. Dekodierung ein. Bei aus dem Schlüsselkanal 48 abgezogenem Schlüssel 2 sorgt der Mikroschalter 56 dafür, dass der Stromkreislauf unterbrochen wird.Electronic elements (not shown), such as data storage devices, are arranged in the cover 9 of the key 2 and are connected to contact points 54 in the contact area 7 of the key 2. These contact points 54 are located on the narrow sides of the key 2 and interact with grinding springs 53. The loop springs 53 are fastened to a printed circuit board 52 and stand over electrical conductors with electronic elements 55 which are on the printed circuit board 52 and / or are arranged externally in connection. A membrane key 57 is integrated into the printed circuit board 52 and is part of a microswitch 56. This microswitch 56 projects into the key channel 48 and has resilient elements (not shown) in its interior. The microswitch 56 can be actuated directly through the narrow side of the key bit 8 or, as shown in FIG. 1, by means of an additional coding on the key 2. When the key 2 is inserted into the cylinder lock 1, the microswitch 56 acts on the membrane key 57 and switches on the circuit for electronic coding or decoding. When the key 2 is removed from the key channel 48, the microswitch 56 ensures that the circuit is interrupted.

Weisen die Nuten 46 und 47 am Schlüsselbart 8 die richtigen mechanischen Kodierungen auf, so befinden sich die mechanischen Zuhaltungen in der Oeffnungsposition, und die mechanischen Verriegelungen geben die Drehbewegung des Rotors 5 im Stator 3 frei. Da in dieser Position der Schlüssel 2 vollständig eingesteckt ist, stehen die Schleiffedern 53 in Kontakt mit den entsprechenden Kontaktstellen 54 am Kontaktbereich 7 des Schlüssels 2. Ueber die Kontakteinrichtung 51 können somit Informationen, bzw. Daten, vom Schlüssel 2 an das Zylinderschloss 1 oder umgekehrt übertragen werden. Die elektronischen Elemente 55 auf der Leiterplatte 52 und eventuell weitere elektronische Elemente, welche dem Zylinderschloss 1 zugeordnet sind, prüfen die Richtigkeit der übertragenen Informationen und stellen fest, ob der in das Zylinderschloss 1 eingesteckte Schlüssel 2 zutrittsberechtigt ist. Sofern die übertragenen Informationen richtig sind und mit den Schlosskodierungen übereinstimmen, wird die Sperreinrichtung 6 freigegeben.If the grooves 46 and 47 on the key bit 8 have the correct mechanical coding, the mechanical tumblers are in the open position and the mechanical interlocks release the rotary movement of the rotor 5 in the stator 3. Since the key 2 is fully inserted in this position, the slide springs 53 are in contact with the corresponding contact points 54 on the contact area 7 of the key 2. Information or data can thus be transferred from the key 2 to the cylinder lock 1 or vice versa via the contact device 51 be transmitted. The electronic elements 55 on the printed circuit board 52 and possibly further electronic elements which are assigned to the cylinder lock 1 check the correctness of the information transmitted and determine whether the key 2 inserted into the cylinder lock 1 is authorized to access. If the transmitted information is correct and matches the lock codes, the locking device 6 is released.

Die Sperreinrichtung 6 besteht aus einem Auslösebolzen 13 und einem Zuhaltungsstift 15, einem Sperrbolzen 14, einem Magnetanker 12 und einer Elektrospule 11. Der Auslösebolzen 13 ist in der gleichen Achse angeordnet wie der Zuhaltungsstift 15 und befindet sich in einer etwa rechtwinkligen Lage zur Achse 10 des Schlosses 1. Das Zusammenwirken zwischen Zuhaltungsstift 15, Auslösebolzen 13 und Magnetanker 12 ist insbesondere in Figur 2 erkennbar. Dabei befindet sich der Zuhaltungsstift 15 in einer Bohrung am Rotor 5 und greift mit seiner Spitze 44 in eine Kantenbohrung 45 an der Schmalseite des Schlüsselbartes 8 ein. Am anderen Ende des Zuhaltungsstiftes 15 befindet sich eine Gleitfläche 43, welche bei richtig positioniertem Zuhaltungsstift 15 mit der Mantelfläche des Rotors 5 deckungsgleich ist. An dieser Gleitfläche 43 des Zuhaltungsstiftes 15 liegt eine Endfläche 17 des Auslösebolzens 13 an. Der Auslösebolzen 13 weist in seinem mittleren Bereich einen Mitnehmer 16 und im unteren Bereich einen gabelförmigen Teil 18 auf. Der gabelförmige Teil 18 schliesst einen Zwischenraum 19 ein, in welchem der Magnetanker 12 geführt ist. Am Ende des gabelförmigen Teiles 18 ist ein zweiter Zwischenraum 20 angeordnet, in welchem eine Druckfeder 21 geführt ist. Diese Druckfeder 21 stösst den Auslösebolzen 13, und damit den Zuhaltungsstift 15, in Richtung des Rotors 5, bzw. der Schlossachse 10. Wenn die Kantenbohrung 45 am Schlüsselbart 8 und die Spitze 44 am Zuhaltungsstift 15 nicht übereinstimmen, liegt die Gleitfläche 43 nicht in der Umfangsfläche des Rotors 5, und der Zuhaltungsstift oder der Auslösebolzen sperren die Drehbewegung des Rotors 5 im Stator 3. Unabhängig von der elektronischen Kodierung ist hiermit eine zusätzliche mechanische Sperre in das Schloss eingebaut.The locking device 6 consists of a release pin 13 and a tumbler pin 15, a locking pin 14, a magnet armature 12 and an electric coil 11. The release pin 13 is arranged in the same axis as the tumbler pin 15 and is in an approximately rectangular position to the axis 10 of the lock 1. The interaction between the tumbler pin 15, the release pin 13 and the armature 12 can be seen in particular in Figure 2. The tumbler pin 15 is located in a bore on the rotor 5 and engages with its tip 44 in an edge bore 45 on the narrow side of the key bit 8. At the other end of the tumbler pin 15 there is a sliding surface 43 which, when the tumbler pin 15 is correctly positioned, is congruent with the lateral surface of the rotor 5. On this sliding surface 43 of the tumbler pin 15 there is an end surface 17 of the release pin 13. The trigger bolt 13 has a driver 16 in its central region and a fork-shaped part 18 in the lower region. The fork-shaped part 18 includes an intermediate space 19 in which the armature 12 is guided. At the end of the fork-shaped part 18, a second space 20 is arranged, in which a compression spring 21 is guided. This compression spring 21 pushes the release pin 13, and thus the tumbler pin 15, in the direction of the rotor 5, or the lock axis 10. If the edge bore 45 on the key bit 8 and the tip 44 on the tumbler pin 15 do not match, the sliding surface 43 is not in the Circumferential surface of the rotor 5, and the tumbler pin or the release bolt block the rotary movement of the rotor 5 in the stator 3. Independently of the electronic coding, an additional mechanical lock is hereby installed in the lock.

Am Mitnehmer 16 des Auslösebolzens 13 liegt an der oberen Fläche eine Mitnehmerschulter 39 des Sperrbolzens 14 auf. Der Sperrbolzen 14 ist im Stator 3 gelagert und greift mit seinem Ende in eine Ringnut 38 am Rotor 5 ein. Diese Ringnut 38 erstreckt sich nur über einen Teilbereich des Mantelumfanges des Rotors 5 und ermöglicht damit eine Teildrehbewegung des Rotors 5 auch dann, wenn der Sperrbolzen 14 in die Nute 38 eingreift. Zwischen der Mitnehmerschulter 39 und dem Stator 3 ist eine Druckfeder 42 angeordnet, welche den Sperrbolzen 14 vom Rotor 5 wegstösst. Das untere Ende 40 des Sperrbolzens 14 läuft konisch zu und weist an der Endfläche eine Schulter 41 auf. Diese Schulter 41 wirkt mit einem Zapfen 36 am Magnetanker 12 zusammen.A driver shoulder 39 of the locking pin 14 lies on the driver 16 of the release pin 13 on the upper surface. The locking pin 14 is mounted in the stator 3 and engages with its end in an annular groove 38 on the rotor 5. This annular groove 38 extends only over a portion of the circumference of the rotor 5 and thus enables a partial rotary movement of the rotor 5 even when the locking pin 14 engages in the groove 38. A compression spring 42 is arranged between the driving shoulder 39 and the stator 3 and pushes the locking pin 14 away from the rotor 5. The lower end 40 of the locking pin 14 is tapered and has a shoulder 41 on the end face. This shoulder 41 interacts with a pin 36 on the magnet armature 12.

Wie in Figur 3 dargestellt weist der Magnetanker 12 ein vorderes Teil 31 und ein hinteres Teil 32 auf. Das vordere Teil 31 ist in der Kernbohrung 50 der Elektrospule 11 und das hintere Teil 32 in einer Bohrung 49 im Statorgehäuse 4 gelagert. Im hinteren Bereich 32 des Magnetankers 12 befindet sich eine Arretierung in der Form einer Vertiefung 34. An diese Vertiefung 34 schliesst in Richtung gegen den vorderen Teil 31 des Magnetankers 12 eine Nute 35 an, wobei zwischen Nute 35 und Vertiefung 34 der Zapfen 36 gebildet ist. Dieser Zapfen 36 weist eine schräge Fläche 37 auf, deren Neigung so gewählt ist, dass die Kraft der Elektrospule genügt, um die Schulter 41 am Sperrbolzen 14 über diese schräge Fläche 37, bzw. den Zapfen 36 zu schieben. Damit rastet der untere Teil 40 des Sperrbolzens 14 in die Vertiefung 34 am Magnetanker 12 ein und gibt die Nute 38 am Rotor 5 vollständig frei. Der Magnetanker 12 weist im weiteren einen Mitnehmer 30 auf, in welchen wie in Figur 1 dargestellt, ein Hebelarm 29 eines Rückstellelementes 26 eingreift. Dieses Rückstellelement 26 ist am Drehpunkt 27 gelagert und weist einen zweiten Hebelarm 28 auf, welcher am Mitnehmer 16 des Auslösebolzens 13 aufliegt. Die beiden Hebelarme 28 und 29 sind federnd ausgebildet, so dass zwischen Magnetanker 12 und Auslösebolzen 13 eine elastische Wirkverbindung besteht. Um eine Verdrehung des Magnetankers 12 zu verhindern, sind parallele Seitenflächen 33 vorhanden, welche im Bereiche des Zwischenraumes 19 am Auslösebolzen 13 von dessen gabelförmigem Teil 18 geführt werden.As shown in FIG. 3, the magnet armature 12 has a front part 31 and a rear part 32. The front part 31 is mounted in the core bore 50 of the electric coil 11 and the rear part 32 in a bore 49 in the stator housing 4. In the rear area 32 of the magnet armature 12 there is a locking device in the form of a depression 34. A groove 35 adjoins this depression 34 in the direction towards the front part 31 of the magnet armature 12, the pin 36 being formed between the groove 35 and the depression 34 . This pin 36 has an inclined surface 37, the inclination of which is selected such that the force of the electrocoil is sufficient to push the shoulder 41 on the locking pin 14 over this inclined surface 37 or the pin 36. The lower part 40 of the locking bolt 14 thus snaps into the recess 34 on the magnet armature 12 and completely releases the groove 38 on the rotor 5. The magnet armature 12 also has a driver 30, in which, as shown in FIG. 1, a lever arm 29 of a restoring element 26 engages. This return element 26 is mounted on the pivot point 27 and has a second lever arm 28 which rests on the driver 16 of the release pin 13. The two lever arms 28 and 29 are resilient, so that there is an elastic operative connection between the magnet armature 12 and the release pin 13. In order to prevent rotation of the magnet armature 12, there are parallel side surfaces 33 which are guided in the area of the intermediate space 19 on the release bolt 13 by its fork-shaped part 18.

Befindet sich kein Schlüssel 2 im Zylinderschloss 1, so wird der Auslösebolzen 13 durch die Feder 21 bis zu einem oberen Anschlag in Richtung des Rotors 5 gestossen. Der Mitnehmer 16 greift mit seiner oberen Fläche in den Sperrbolzen 14 ein, indem die untere Fläche der Mitnehmerschulter 39 des Sperrbolzens 14 am Mitnehmer 16 des Auslösebolzens 14 aufliegt. Dadurch wird der Sperrbolzen 14 gegen die Kraft der Feder 42 in die Nute 38 am Rotor 5 eingerückt und sperrt diesen gegen vollständiges Verdrehen. Gleichzeitig drückt der Auslösebolzen 13 den am Mitnehmer 16 aufliegenden Hebelarm 28 des Rückstellelementes 26 nach oben und schiebt über den zweiten Hebelarm 29 den Magnetanker 12 bis zum Anschlag in die Bohrung 49. Damit befindet sich die Sperreinrichtung in der normalen Ausgangslage. Wird nun ein Schlüssel 2 in das Zylinderschloss 1 eingesteckt, so werden die nicht dargestellten mechanischen Zuhaltungen in ihre Oeffnungspositionen geschoben, sofern der Schlüssel mechanisch richtig kodiert ist und über den Mikroschalter 56 wird der Stromkreis der Einrichtung zum Uebertragen der Informationssignale eingeschaltet. Damit beginnt der Austausch von elektronischen Informationen zwischen dem Schlüssel 2 und dem Zylinderschloss 1. Stimmt die elektronische Kodierung des Schlüssels 2 mit derjenigen des Zylinderschlosses 1 überein, so wird die Sperreinrichtung 6 freigegeben, indem die Elektrospule 11 erregt wird. Gleichzeitig mit der Positionierung der mechanischen Zuhaltungen wird auch der Zuhaltungsstift 15, und damit der Auslösebolzen 13, in die Oeffnungsposition gebracht. Dadurch bewegt sich der Sperrbolzen 14 in Richtung des Magnetankers 12, bis sein unteres Ende mit der Schulter 41 in die Nute 35 am Magnetanker 12 eingreift. Da die Schulter 41 am Sperrbolzen 14, und der Zapfen 36 am Magnetanker 12 gegeneinander wirken, sperrt der Magnetanker 12 vorerst die weitere Bewegung des Sperrbolzens 14. Der Rotor kann somit nur soweit verdreht werden, als am Umfange eine entsprechende Nut 38 angeordnet ist. Sollte die elektronische Kodierung des Schlüssels 2 nicht mit dem Schloss 1 übereinstimmen, kann der Rotor 5 auch bei Uebereinstimmung der mechanischen Zuhaltungen nicht vollständig gedreht, und damit das Schloss nicht geöffnet werden. Stimmt die elektronische Kodierung des Schlüssels 2 mit derjenigen des Zylinderschlosses 1 überein, so wird während der Drehbewegung des Rotors 5, mit Hilfe des Schlüssels 2 im Bereiche der Ringnute 38 durch die elektronische Steuerung die Elektrospule 11 aktiviert und der Magnetanker 12 in die Kernbohrung 50 eingezogen. Die Schulter 41 am Sperrbolzen 14 überspringt dabei den Zapfen 36 und das untere Ende 40 rastet in die Vertiefung 34 ein. Da die Feder 42 den Sperrbolzen 14 gegen den Magnetanker 12 drückt, kann die Stromzufuhr zur Elektrospule 11 sofort unterbrochen werden, wodurch der Stromverbrauch dieser Einrichtung ausserordentlich gering ist. Wird der Schlüssel 2 wieder aus dem Zylinderschloss 1 abgezogen, unterbricht der Mikroschalter 56 auch den Steuerstrom zu den übrigen elektrischen und elektronischen Bauelementen, was zu einer wesentlich erhöhten elektrischen Sicherheit und Lebensdauer der Stromquellen führt.If there is no key 2 in the cylinder lock 1, the release pin 13 is pushed by the spring 21 up to an upper stop in the direction of the rotor 5. The driver 16 engages with its upper surface in the locking pin 14 in that the lower surface of the driver shoulder 39 of the locking pin 14 rests on the driver 16 of the release pin 14. This will lock the bolt 14 engages against the force of the spring 42 in the groove 38 on the rotor 5 and locks it against complete rotation. At the same time, the release pin 13 presses the lever arm 28 of the restoring element 26 resting on the driver 16 and pushes the magnetic armature 12 into the bore 49 as far as it will go via the second lever arm 29. The locking device is thus in the normal starting position. If a key 2 is now inserted into the cylinder lock 1, the mechanical tumblers, not shown, are pushed into their opening positions, provided the key is mechanically correctly coded and the circuit of the device for transmitting the information signals is switched on via the microswitch 56. This begins the exchange of electronic information between the key 2 and the cylinder lock 1. If the electronic coding of the key 2 matches that of the cylinder lock 1, the locking device 6 is released by energizing the electric coil 11. Simultaneously with the positioning of the mechanical tumblers, the tumbler pin 15, and thus the release pin 13, is also brought into the open position. As a result, the locking bolt 14 moves in the direction of the magnet armature 12 until its lower end engages with the shoulder 41 in the groove 35 on the magnet armature 12. Since the shoulder 41 on the locking pin 14 and the pin 36 on the magnet armature 12 act against each other, the magnet armature 12 initially blocks the further movement of the locking pin 14. The rotor can thus only be rotated to the extent that a corresponding groove 38 is arranged on the circumference. If the electronic coding of the key 2 does not match the lock 1, the rotor 5 cannot be rotated completely even if the mechanical tumblers match, and thus the lock cannot be opened. If the electronic coding of the key 2 matches that of the cylinder lock 1, the electronic control 11 is activated by the electronic control and the magnet armature 12 is drawn into the core bore 50 during the rotary movement of the rotor 5 with the aid of the key 2 in the region of the ring groove 38 . The shoulder 41 on the locking pin 14 jumps over the pin 36 and the lower end 40 engages in the recess 34. Since the spring 42 presses the locking pin 14 against the magnet armature 12, the power supply to the electrocoil 11 can be interrupted immediately, as a result of which the power consumption of this device is extremely low. If the key 2 is removed again from the cylinder lock 1, the microswitch 56 also interrupts the control current to the other electrical and electronic components, which leads to a significantly increased electrical safety and service life of the power sources.
