Abstract

The invention relates to a locking cylinder comprising a cylinder core that is rotatably mounted in the locking cylinder housing, core and housing pins, which can be displaced by a mechanically coded key into a position of alignment on the separation plane of locking cylinder housing and cylinder core, thus permitting the rotation of the cylinder core, in addition to an electric/electronic blocking device, which is located in the locking cylinder housing and can be controlled by an electronic coding of the key. The blocking device has an actuating element (15) that can be displaced by the rotation of the cylinder core in the locking cylinder housing. Said element co-operates with a spring element (14), which in turn is connected to a blocking element (13). To achieve the blocking position, said blocking element can be pressed into a recess on the inner periphery of the locking cylinder housing by the spring force, thus overlapping the separation plane of locking cylinder housing and cylinder core. In this blocking position, the blocking element (13) is prevented from moving out of the blocking position by an adjusting element (9) that forms part of the electric/electronic blocking device.

Schließzylinder lock cylinder
Beschreibungdescription
Die Erfindung betrifft einen Schließzylinder mit einem im Schließ∑ylindergehäuse drehbar gelagerten Zylinderkem sowie mit Kern- und Gehäusestiften, die von einem mechanisch codierten Schlüssel in eine die Drehung des Zylinderkernes ermöglichende Abgleichposition an der Trennebene Schließzylindergehäuse/Zylinderkern bewegbar sind, sowie einer im Schließzylindergehäuse angeordneten elektrisch/elektronischen Sperreinrichtung, die von einer elektronischen Codierung des Schlüssels steuerbaren ist.The invention relates to a lock cylinder with a cylinder housing rotatably mounted in the cylinder housing and with core and housing pins, which are movable by a mechanically coded key in a rotation of the cylinder core enabling adjustment position on the parting plane lock cylinder housing / cylinder core, and arranged in a lock cylinder housing electrically / electronic locking device, which is controllable by an electronic coding of the key.
Bekannt sind aus der Praxis Schließzylinder mit einem elektronischen Lesekopf, der beispielsweise mit einem Magnetanker zusammenwirkt, der seinerseits ein Sperrelement aufweist, das die Drehung des Zylinderkernes verhindert.Are known in practice lock cylinder with an electronic read head, which cooperates for example with a magnetic armature, which in turn has a blocking element which prevents the rotation of the cylinder core.
Aufgabe der Erfindung ist es, den Aufbau eines derartigen Schließzylinders zu vereinfachen und bei einer Gewalteinwirkung aufgebrachte Kräfte von - vergleichsweise - empfindlicheren Steuerteilen der Sperreinrichtung fernzuhalten.The object of the invention is to simplify the structure of such a lock cylinder and applied forces of - relatively less sensitive control parts of the locking device to keep away from a force acting.
Gelöst wird diese Aufgabe durch die Merkmale des Patentanspruchs 1. Vorzugsweise Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved by the features of claim 1. Preferably embodiments will be apparent from the dependent claims.
Kern der Erfindung ist die Trennung der die Bewegung der einzelnen Elemente der Sperreinrichtung bewirkenden Teile von einer möglichen Krafteinwirkung von außen. Hierzu ist das Sperrelement so ausgebildet, dass es sich in seiner Sperrstellung, die Trennebene Schließzylindergehäuse/Zylinderkern übergreifend, in einer Ausnehmung im Schließzylindergehäuse befindet. Normalerweise sichert der Rotor des Verstellelementes das Sperrelement in dieser Position gegen eine Rückbewegung in die Offenstellung. Sollte nun aber von außen Gewalt auf den Zylinderkern ausgeübt werden, so bewirkt die Ausbildung des Sperrelementes und das Zusammenwirken mit der Ausnehmung, bzw. der Form der Ausnehmung, ein Abheben des Sperrelementes vom Rotor des Verstellelementes und ein Verklemmen des Sperrelementes in der Ausnehmung, d.h. alle Kräfte werden durch das Sperrelement aufgenommen und wirken sich nicht auf den Rotor aus. Die Erfindung soll nachfolgend an einem in den Zeichnungen dargestellten Ausführungsbeispiel erläutert werden.The essence of the invention is the separation of the movement of the individual elements of the locking device causing parts of a possible external force. For this purpose, the blocking element is designed so that it is in its locking position, the parting plane lock cylinder housing / cylinder core cross, in a recess in the lock cylinder housing. Normally, the rotor of the adjusting element secures the blocking element in this position against a return movement into the open position. If, however, violence is exerted on the cylinder core from the outside, then the formation of the blocking element and the interaction with the recess, or the shape of the recess, causes the blocking element to be lifted off the rotor of the adjusting element and jamming of the blocking element in the recess, ie All forces are absorbed by the blocking element and do not affect the rotor. The invention will be explained below with reference to an embodiment shown in the drawings.

Mit 1 ist das Zylindergehäuse mit der Gewindebohrung für die Stulpschraube bezeichnet und mit 2 der Zylindβrkern. Der Schlüssel selbst ist nicht dargestellt. Mit 7 ist der für die verschiedensten Schlüsselprofile, einschließlich eventueller Rippen- oder Sondeφrofile, vorgesehene Schlüsselkanal angedeutet.With 1, the cylinder housing is designated with the threaded hole for the forend screw and with 2 of the Zylindβrkern. The key itself is not shown. With 7 of the various key profiles, including any rib or Sondeφrofile, provided key channel is indicated.
Zunächst soll die sog. gegen Manipulation schützende An- oder Abwesenheitskontrolle bzw. Detektion des Schlüssels durch einen angeformteπ oder eingesteckten seitlichen Ausleger 8 an mindestens einem der Kernstifte 4 ', vorzugsweise an dem vom Schlüsselanschlag gesehen ersten Kemstift, bei dem die zugehörige erste Schlüsselkerbe aus Stabilitätsgründen des Schlüssels nicht auf die maximale Tiefe gefräst worden ist, erläutert werden. Unabhängig von dieser Besonderheit nutzt die erfindungsgemäße Detektion des Schlüssels die Tatsache, dass bei abgezogenem Schlüssel alle Kernstifte von den zugehörigen Gehäusestiften und Stiftfedern in eine von der meist gleichen Bohrungstiefe der Stiftlöcher und Kern vorgegebene Endlage gedrückt werden, die sie bei eingestecktem Schlüssel, auch bei maximaler Kerbentiefe, nicht erreichen. Diese Wegdifferenz, welche aus vorgenanntem Grund beim ersten Stift besonders groß ist, wird am seitlichen Ausleger 8 des jeweils detektierten Kernstiftes 4 abgetastet, kann gemessen und ausgewertet oder, wie in der dargestellten Ausführung der Erfindung, zum Freigeben, Zurückdrehen und Sperren des Verstellelementes 9 genutzt werden. Weil der Stiftausleger 8 des jeweiligen Sperrstift um dessen gesamten Weg verfahren wird, ist dafür eine seitliche, diesem Stiftweg entsprechende Aussparung 29 vorgesehen.First, the so-called. Against tamper-evident presence or absence control or detection of the key by a molded or inserted side arm 8 on at least one of the core pins 4 ', preferably on the first Kemstift seen from the key stop, in which the corresponding first key notch for stability reasons the key has not been milled to the maximum depth can be explained. Regardless of this peculiarity, the detection of the key according to the invention utilizes the fact that, when the key is removed, all the core pins are pressed by the associated housing pins and pin springs into an end position predetermined by the usually same hole depth of the pin holes and core, which they hold when the key is inserted, even at maximum Notch depth, not reach. This path difference, which for the aforementioned reason is particularly great in the case of the first pin, is scanned on the lateral arm 8 of the respectively detected core pin 4, can be measured and evaluated or, as in the illustrated embodiment of the invention, used for releasing, turning back and locking the adjusting element 9 become. Because the pin arm 8 of the respective locking pin is moved around its entire path, a lateral recess 29 corresponding to this pin path is provided for this purpose.
Im Zylinderkern ist - bei dieser Ausführungsform - ein Motor 12 angeordnet, der mit einem Verstellelement 9 verbunden ist, das als zweiarmiger Rotor ausgebildet ist. Zu der in Figur 4 gezeichneten Position des Verstellelementes ist anzumerken, dass sich dieses in geringem Abstand vom Sperrelement befindet. In der gezeichneten Stellung kann das sich in der sperrenden Position befindliche Sperrelement 13 nicht nach innen, also in die freigebende Position verschoben werden. Erst wenn der Rotor, also das Verstellelement, um etwa 90 Grad nach links verdreht wird, kann das Sperrelement nach innen in die Freigabestellung verfahren werden. Dabei ist von Bedeutung, dass im Ruhezustand zwischen der Anlagefläche des Sperrelementes 13 und dem sperrenden Rotor desIn the cylinder core is - in this embodiment - a motor 12 is arranged, which is connected to an adjusting element 9, which is designed as a two-armed rotor. To the drawn in Figure 4 position of the adjustment is to be noted that this is located at a small distance from the blocking element. In the drawn position, the Locking element 13 located in the blocking position is not displaced inward, that is to say into the releasing position. Only when the rotor, so the adjustment, is rotated by about 90 degrees to the left, the locking element can be moved inwards to the release position. It is important that in the resting state between the contact surface of the blocking element 13 and the blocking rotor of the
Verstellelementes 9 ausreichend Abstand 30 bzw. Spiel vorhanden ist, damit der MotorVerstellelementes 9 sufficiently distance 30 or play is present, so that the engine
12 das Verstellelement 9 frei und ohne Reibwiderstand in die Freigabestellung drehen kann. In die Sperrstellung (Fig.4) gedreht wird das Verstellelement 9 durch den Stiftausleger 8 (Fig.3), sobald der Schlüssel abgezogen wird. Der Stiftausleger 8 fixiert das Verstellelement 9 dann auch in der Sperrstellung, bis wieder ein mechanisch berechtigter Schlüssel eingesteckt wird. Damit sich das Verstellelement 9 in beide Drehrichtungen nur etwa 90 Grad drehen kann, ist der Anschlag 10 vorgesehen.12 can rotate the adjustment 9 freely and without frictional resistance in the release position. In the blocking position (Figure 4), the adjusting element 9 is rotated by the pin arm 8 (Figure 3), as soon as the key is removed. The pin arm 8 then fixes the adjusting element 9 in the blocking position until a mechanically authorized key is again inserted. Thus, the adjusting element 9 can rotate in both directions only about 90 degrees, the stopper 10 is provided.
In seiner Freigabestellung wird das Verstellelement 9 durch Magneten (nur gezeigt 19) gehalten.In its release position, the adjusting element 9 is held by magnets (only shown 19).
Wesentlich für die Erfindung ist die sich vom Verstellelement 9 lösende und dieses völlig freigebende Funktion des Sperrelementes 13 im Zusammenwirken mit dem längs angeordneten Federstab 14 und dem Betätigungselement 15 sowie der zugehörigen segmentförmigen Ausnehmung 20, mit Abgleitflächen 31 für die entsprechendeEssential to the invention is the adjusting element 9 solving and this completely releasing function of the locking element 13 in cooperation with the longitudinally arranged spring bar 14 and the actuating element 15 and the associated segment-shaped recess 20, with sliding surfaces 31 for the corresponding
Gegenkontur des Sperrelementes 13, im Gehäuse 1. Der unbelastet gerade Federstab ist auf der einen Seite zwischen der als Stablager 17 bezeichneten Bohrung im Einschubköφer 11 und der über dem Motor 12 liegenden Brücke 16 so eingespannt, dass er, am anderen Ende in die Hülse 18 des radial verschiebbaren Sperrelementes 13 eingreifend, dieses stets radial nach außen, also in dessen radial sperrende Position drückt, wo es in Eingriff mit den Abgleitschrägen der Ausnehmung 20 steht bzw. bei Drehung des Zylinderkernes bringbar ist. An geeigneter Stelle zwischen dieser quasi festen Einspannung und dem SperrelementCounter contour of the locking element 13, in the housing 1. The unloaded straight spring bar is clamped on one side between the designated as a rod bearing 17 hole in Einschubköφer 11 and over the motor 12 bridge 16 so that he, at the other end into the sleeve 18th the radially displaceable locking element 13 engaging, this always radially outwardly, ie in the radially blocking position presses, where it is in engagement with the Abgleitschrägen the recess 20 and can be brought upon rotation of the cylinder core. At a suitable point between this quasi-firm clamping and the blocking element
13 ist dem Federstab 14 ein Betätigungselement 15 genanntes, radial verschiebbares Element aufgesetzt, welches in eine Ausnehmung an der Innenseite des13, the spring rod 14, an actuating element 15 mentioned, radially displaceable element is placed, which in a recess on the inside of the
Schließzylindergehäuses 1 greift und dadurch beim Drehen des Zylindβrkernes 2 radial nach innen verschoben wird und über den Federstab 14 auch das Sperrelement 13 radial nach innen, also in die freigebende Position, zu bewegen versucht. Wenn vorher die elektronische Freigabe erfolgt ist, das Verstellelement 9 vom Motor 12 also bereits in die Offenposition gedreht worden ist, kann diese Bewegung auch erfolgen. Der Zylinderkern kann dann frei gedreht werden, d.h. ein Aufschließen ist möglich.Lock cylinder housing 1 engages and is thereby displaced radially inwardly upon rotation of the Zylindπrkernes 2 and tried over the spring bar 14 and the locking element 13 radially inwardly, ie in the releasing position to move. If previously the electronic release has taken place, the adjusting element 9 has thus already been rotated by the motor 12 in the open position, this movement can also take place. The cylinder core can then be rotated freely, ie unlocking is possible.
Sollte der eingesteckte Schlüssel dagegen elektronisch nicht berechtigt sein, das Verstellelement 9 also in Figur 4 gezeichneten, sperrenden Position verbleiben, kann das Sperrelement 13 nur um den Betrag des Abstandes zwischen seiner Anlagefläche und dem Verstellelement 9 nach innen bewegt werden. Die weitere Verschiebung des Betätigungselementes 15 wird beim weiteren Drehen des Zylinderkemes 2 als Durchbiegung des Federstabes elastisch aufgenommen. Beim weiteren Drehen des Zylinderkemes kommt dann das um den Betrag des Abstandes 30 zum sperrenden Balken des Verstellelementes durch den Federstab 14 nach innen gedrückteOn the other hand, should the inserted key not be electronically authorized, the adjusting element 9 thus remain in the blocking position shown in FIG. 4, the blocking element 13 can only be moved inwards by the amount of the distance between its contact surface and the adjusting element 9. The further displacement of the actuating element 15 is elastically received during further rotation of the cylinder core 2 as deflection of the spring bar. Upon further rotation of the cylinder core then comes to the amount of the distance 30 to the blocking beam of the adjustment by the spring rod 14 pressed inwards
Sperrelemβnt in der segmentförmigen Gehäuseausnehmung 20 zur Anlage. Dabei sind die beidseitig hakenförmige Außenkontur des Sperrelementes 13 und die zugehörigen Abgleitflächen im segmentförmig ausgefrästen Bereich 20 des Schließzylindergehäuses 1 so gestaltet, dass das Sperrelement 13 bei Belastung zumindest um den Betrag des Abstandes 30 radial nach außen, also vom sperrenden Balken des Verstellelementes 9 weggezogen wird. Das bringt den entscheidenden Vorteil, dass alle beim versuchten Weiterdrehen des Schlüssels eingeleiteten Kräfte allein zwischen Schließzylindergehäuse 1 und dem Sperrelement wirken und alle sensiblen Teile wie z.B. Verstellelement 9, Motor 12 und Stiftausieger 8 mechanisch von der Krafteinflusszone getrennt sind. Darüber hinaus ist es für die Abstützung der vom Schlüssel oder unerlaubten Hilfsmitteln eingeleiteten Drehmomenten auf den Zylinderkem 2 wichtig, dass das Sperrelement 13 zumindest teilweise, im gezeichneten Beispiel mit seiner Schulter, direkt in der Ausfräsung des metallischen Zylinderkemes 2 geführt ist und bei Belastung dort auch abgestützt wird. Die segmentförmige Ausnehmung 20 im Zylindergehäuse ist von der Außenseite her eingefräst und mit einer eingedrückten Abdeckung 21 geschützt.Sperrelemβnt in the segmental housing recess 20 to the plant. The two-sided hook-shaped outer contour of the locking element 13 and the associated Gleitleitflächen in the segment-shaped milled area 20 of the lock cylinder housing 1 are designed so that the locking element 13 is pulled under load at least by the amount of the distance 30 radially outward, ie from the locking beam of the adjusting element 9 , This has the decisive advantage that all forces introduced during the attempted further rotation of the key act solely between the lock cylinder housing 1 and the blocking element and all sensitive parts such as e.g. Adjustment element 9, motor 12 and pin ejector 8 are mechanically separated from the force-influencing zone. In addition, it is important for the support of the introduced by the key or unauthorized means torques on the cylinder core 2 that the blocking element 13 is at least partially, in the example shown with his shoulder, guided directly into the cutout of the metallic cylinder core 2 and under load there as well is supported. The segment-shaped recess 20 in the cylinder housing is milled from the outside and protected with a depressed cover 21.
Eine weitere Besonderheit der Erfindung ist die Anordnung zur Führung aller im Zylinderkem 2 angeordneten mechanischen Bauteile der Sperrvorrichtung in einer kompakten Baugruppe, deren tragendes und umfassendes Element in der Zeichnung als zweckmäßig in Kunststoff ausgeführter Einschubkörper 11 bezeichnet wird. Diese Baugruppe kann kostensparend ausgeführt und separat vorgefertigt werden und wird bei der Montage nur in eine im wesentlichen rechteckige Ausfräsung des Zylinderkernes eingesetzt. Auf der Gegenseite des Zylinderkemes 2 sind alle schlossseitigen elektronischen Bauteile 22 angeordnet, auf die hier nicht näher eingegangen wird. Normalerweise könnten diese, zu einem vorgefertigten Kunststoffblock vergossen, eingesetzt werden, was jedoch Schwierigkeiten bei der Montage bereitet, weil ja zumindest die Verbindungen vom Motor auf der anderen Seite des Zylinderkemes 2 angeschlossen werden müssen. Darum wurde als eine Variante der erfindungsgemäßen Ausführung der Elektronikbereich nur gegen Korrosion geschützt, ansonsten aber frei zugänglich gelassen und mit einer aus Blech hergestellten, vorgeformten und in Bohrungen einrastenden Abdeckung versehen, was sich außerordentlich bewährt hat.Another special feature of the invention is the arrangement for guiding all arranged in Zylinderkem 2 mechanical components of the locking device in a compact assembly, the supporting and comprehensive element is referred to in the drawing as appropriate in plastic running insert body 11. This assembly can be carried out cost-saving and prefabricated separately and is used in the assembly only in a substantially rectangular cutout of the cylinder core. On the opposite side of the cylinder core 2 all lock-side electronic components 22 are arranged, which will not be discussed here. Normally, these could be cast into a prefabricated plastic block, but this causes difficulties in assembly, because at least the connections from the engine on the other side of the cylinder core 2 must be connected. Therefore, as a variant of the embodiment of the invention, the electronics area was protected only against corrosion, but otherwise left freely accessible and provided with a made of sheet metal, preformed and snap-in holes cover, which has proven extremely useful.
Unter diesem Abdeckblech hat auch die Verbindungsleitung 27 von der Leiterplatte zum federnd beweglichen Kontaktstift 24 ausreichend Bewegungsfreiheit. Das Kontaktelement kann auch beidseitig angeordnet sein oder an anderer Stelle des Schlüssels angreifen. Das eigentliche zum Schlüssel kontaktgebende Element, hier der Kontakt 24, ist isoliert in einer Kontakthülse 25 und unter Federdruck beweglich angeordnet, um Verschleiß und Maßdifferenzen auszugleichen. Under this cover plate and the connection line 27 of the circuit board for resiliently movable contact pin 24 has sufficient freedom of movement. The contact element can also be arranged on both sides or attack at another point of the key. The actual key contact element, here the contact 24 is isolated in a contact sleeve 25 and arranged movable under spring pressure to compensate for wear and dimensional differences.
