Ein Vorreiberverschluß mit den vorgenannten Merkmalen ist in der EP 0 504 144 B1 beschrieben; in dem formschlussig in einem zugeordneten Türdurchbruch festzulegenden Gehäuse des Vorreiberverschlusses ist bei einem Ausführungsbeispiel (Figur 12) ein Schließzylinder für einen Sicherheitsschlüssel angeordnet. Der Schließzylinder ist mit einer stirnseitig angesetzten Verriegelungszunge verbunden derart, daß eine Drehung des in den Schließzylinder eingesteckten Sicherheitsschlüssels in eine Drehung der Verriegelungszunge zwischen ihrer Entriegelungsstellung und ihrer Verriegelungsstellung umgesetzt wird.A cam lock with the aforementioned features is described in EP 0 504 144 B1; by doing form-fitting in an assigned door opening housing of the sash lock to be determined in one embodiment (Figure 12) Lock cylinder for a security key arranged. The lock cylinder is with a connected locking tongue connected at the front such that a rotation of the in the lock cylinder inserted security key in a rotation of the Locking tongue between their unlocked position and its locking position is implemented.

Mit einem derartigen Vorreiberverschluß ist der Nachteil verbunden, daß das über den Schließzylinder bzw. über die Drehung des Schlüssels aufzubringende Anzugsmoment für das Verdrehen der Verriegelungszunge zwischen ihrer Entriegelungsstellung und ihrer Verriegelungsstellung nicht ausreichend groß ist; stehen nämlich Tür und Schrankkorpus unter gegenseitiger Spannung, so besteht die Gefahr, daß die zur Verdrehung der Verriegelungszunge aufzubringende Kraft zu einem Abbrechen des Schlüssels oder zu einer Beschädigung des Schließzylinders führt. Weiterhin ist die Sicherheit des Vorreiberverschlusses gegen Vandalismus nicht ausreichend; wird nämlich der Schließzylinder mutwillig zerstört oder so beschädigt, daß der passende Schlüssel nicht mehr einsteckbar ist, so muß der gesamte Vorreiberverschluß ausgewechselt werden.With such a cam lock is the Disadvantage connected that the lock cylinder or to be applied via the rotation of the key Tightening torque for turning the locking tongue between their unlocked position and their Locking position is not sufficiently large; the door and cabinet body are under mutual tension, there is a risk that the to be applied to twist the locking tongue Force to break the key or to Damage to the lock cylinder leads. Still is the security of the cam lock against Vandalism insufficient; namely the Lock cylinder willfully destroyed or so damaged, that the appropriate key can no longer be inserted, the entire cam lock must be replaced become.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Vorreiberverschluß mit den eingangs genannten Merkmalen die vorgenannten Nachteile zu beseitigen und stirnseitig am Gehäuse angeordneten Verriegelungszunge eingreift, so daß die Verdrehung der Verriegelungszunge über die gesonderte Betätigung erfolgt. Im Anschluß daran kann der Schließzylinder wieder in den Gehäusekanal des Gehäuses eingesetzt und darin verriegelt werden. Erfolgt eine beabsichtigte oder auch unbeabsichtigte Zerstörung des Schließzylinders, so kann der Schließzylinder aus dem Gehäuse herausgebohrt werden, wonach der Vorreiberverschluß gleichwohl betätigbar ist und lediglich der Schließzylinder anschließend zu erneuern ist.The invention is therefore based on the object a cam lock with the aforementioned Features to eliminate the aforementioned disadvantages and Locking tongue arranged on the front of the housing engages so that the rotation of the locking tongue via the separate actuation. In connection the locking cylinder can then be put back into the Housing channel of the housing used and in it be locked. Is there an intended or also accidental destruction of the lock cylinder, see above the lock cylinder can be drilled out of the housing after which the tamper-evident closure nonetheless can be operated and only the lock cylinder then to be renewed.

Nach einem Ausführungsbeispiel der Erfindung ist zur Festlegung des Schließzylinders in dem Gehäuse vorgesehen, daß das Gehäuse einen in seinen Gehäusekanal vorstehenden Stift und der Schließzylinder eine über einen äußeren Umfangsabschnitt verlaufende Nut mit einem axialen, sich bis zum freien Stirnende des Schließzylinders erstreckenden Nutfortsatz zum Eingriff des Stiftes aufweist.According to an embodiment of the invention Fixing the locking cylinder in the housing provided that the housing one in its Housing channel protruding pin and the lock cylinder one extending over an outer peripheral portion Groove with an axial, extending to the free end of the lock cylinder extending groove extension to Has engagement of the pin.

Da erfindungsgemäß der Schließzylinder von der Verriegelungszunge entkoppelt ist, ist nach einem Ausführungsbeispiel der Erfindung die Verriegelungszunge in einem am Gehäuse gehalterten und gegenüber dem Gehäuse zwischen der Entriegelungsstellung und der Verriegelungsstellung der Verriegelungszunge drehbaren Buchse festgelegt, wobei nach einem bevorzugten Ausführungsbeispiel der Erfindung die Buchse als auf die Außenseite des trotz Verwendung eines Schließzylinders als Zugangssicherung ein hohes Anzugsmoment für die Betätigung der Verriegelungszunge zu ermöglichen.Since according to the invention the lock cylinder of the Locking tongue is decoupled after one Embodiment of the invention Locking tongue in a and held on the housing opposite the housing between the Unlocking position and the locking position of the Locking tongue rotatable socket set, being according to a preferred embodiment of the Invention the socket as on the outside of the despite using a lock cylinder as Access security a high tightening torque for the To enable actuation of the locking tongue.

Mit der Erfindung ist der Vorteil verbunden, daß der Schließzylinder nur noch der Sicherung des Vorreiberverschlusses gegen unbefugtes Öffnen dient, nicht aber mehr zur Betätigung der Verriegelungszunge herangezogen wird. Nach dem Einstecken des Schlüssels und dem Verbringen in die Entsperrstellung kann nämlich der gesamte Schließzylinder in dem Gehäuse gedreht und aus seiner formschlüssigen Verbindung mit dem Gehäuse herausgenommen werden; anschließend erfolgt das Einstecken einer gesonderten Betätigung in den jetzt freien Gehäusekanal, die in die Betätigungsöffnung der Gehäuses rückwärtig aufgestülpte Überwurfbuchse ausgebildet sein kann.The basic idea of the invention provides that the locking cylinder always from the locking tongue decoupled and in the housing with the key removed locked and with inserted and in the Unlocked key moved out of the housing is removable and that the held on the housing Locking tongue an actuation opening for positive engagement one in the through Remove the lock cylinder from the housing free housing channel insertable actuation. The advantage of the invention is that the Lock cylinder only securing the Latch lock against unauthorized opening, but no longer to operate the locking tongue is used. After inserting the key and moving to the unlocked position can namely the entire lock cylinder is rotated in the housing and from its positive connection with the housing be taken out; then this is done Insert a separate actuation in the now free housing channel that in the opening of the Union sleeve slipped onto the rear of the housing can be trained.

Zur Herstellung einer die erforderliche Relativdrehung der die Verriegelungszunge tragenden Überwurfbuchse gegenüber dem Gehäuse ermöglichenden Formschlußverbindung ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, daß das Gehäuse außenseitig eine Ringnut aufweist und in der Wandung der Überwurfbuchse zwei sekantenartig verlaufende Einsteckkanäle zur Aufnahme einer in die Überwurfbuchse einsteckbaren und mit ihren Federschenkeln radial in die Ringnut des Gehäuses eingreifenden Klammerfeder ausgebildet ist. Damit ist eine besonders einfach zu montierende und in der Handhabung sichere Verbindung gewährleistet.To produce the required relative rotation the union sleeve carrying the locking tongue compared to the housing Positive connection is according to an embodiment the invention provided that the housing outside has an annular groove and in the wall of the Union sleeve two secant Push-in channels for receiving one in the union sleeve insertable and with their spring legs radially in the annular groove of the housing engaging clamp spring is trained. This makes one particularly easy to assembling and safe to use connection guaranteed.

Nach einem Ausführungsbeispiel der Erfindung ist auch zur Erleichterung der Montage die Verriegelungszunge in der Überwurfbuchse formschlüssig festgelegt, und sie wird durch die Montage der Überwurfbuchse auf dem Gehäuse gehalten.According to an embodiment of the invention is also the locking tongue in to facilitate assembly the union bush form-fitting, and she is achieved by mounting the union sleeve on the Housing held.

Es kann weiterhin vorgesehen sein, daß die Verriegelungszunge einen zum Gehäuse vorstehenden und in einen den Drehwinkel der Verdrehung der Überwurfbuchse gegenüber dem Gehäuse festlegenden, in der Stirnseite des Gehäuses ausgebildeten Rücksprung eingreifenden Ansatz aufweist. It can also be provided that the Locking tongue protruding to the housing and in a the angle of rotation of the twist Union sleeve against the housing, in the recess formed on the end face of the housing engaging approach.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung wiedergegeben, welches nachstehend beschrieben ist. Die einzige Figur zeigt einen Vorreiberverschluß mit zusammengefügten Einzelteilen in einer seitlichen Schnittansicht.In the drawing, an embodiment of the Invention reproduced which below is described. The only figure shows one Cam lock with assembled individual parts in a side sectional view.

Der Vorreiberverschluß besteht aus einem Gehäuse 10, welches an seinem einen Ende einen sich an ein nicht dargestelltes Türblatt oder Schrankkorpus anlegenden Flansch 11 aufweist. Im Inneren des Gehäuses erstreckt sich axial ein Gehäusekanal 12, in dem ein Schließzylinder 13 angeordnet ist, in den ein mit dem Bezugszeichen 26 angedeuteter Schlüssel eingeschoben ist so, daß die Zuhaltungen 14 in ihre Entsperrstellung gefallen sind.The cam lock consists of a housing 10, which at one end does not adhere to one the door leaf or cabinet body shown Has flange 11. Extends inside the case axially a housing channel 12 in which a Lock cylinder 13 is arranged in the one with the Reference number 26 indicated key inserted is such that the tumblers 14 in their unlocked position have fallen.

In seinem vorderen, im Inneren des Gehäusekanals 12 liegenden Bereich weist der Schließzylinder 13 eine radial über dessen Umfang verlaufende Nut 15 auf, die in einen sich in axialer Richtung bis zum freien vorderen Stirnende des Schließzylinders 13 erstreckenden Nutfortsatz 16 übergeht. Korrespondierend weist das Gehäuse 10 einen in seinen Gehäusekanal 12 vorstehenden und in den Nutfortsatz 16 bzw. die Nut 15 eingreifenden Stift 17 auf.In its front, inside the housing channel 12 the locking cylinder 13 has a lying area groove 15 extending radially over the circumference thereof in an axial direction until free front end of the lock cylinder 13 extending groove extension 16 passes. corresponding the housing 10 has one in its housing channel 12 protruding and in the groove extension 16 and the groove 15th engaging pin 17.

Auf das dem Flansch 11 abgewandte Ende des Gehäuses ist eine als Überwurfbuchse 18 ausgebildete Buchse aufgeschoben, in welcher eine Verriegelungszunge 19 formschlüssig mittels einer nicht dargestellten Formschlußgestaltung festgelegt ist; die Verriegelungszunge 19 weist eine in Verlängerung des Gehäusekanals 12 liegende Betätigungsöffnung 20 zum Eingriff einer nicht dargestellten Betätigung auf.On the end of the housing facing away from the flange 11 a socket designed as a sleeve 18 pushed in which a locking tongue 19th positively by means of a not shown Form-fitting design is defined; the Locking tongue 19 has an extension of Housing channel 12 lying actuating opening 20 for Engagement of an actuation, not shown.

Die Überwurfbuchse 18 ist mit dem Gehäuse 10 formschlüssig, aber gegenüber dem Gehäuse 10 drehbar dadurch verbunden, daß in der Wandung der Überwurfbuchse zwei sekantenartig verlaufende Einsteckkanäle 24 angeordnet sind, zu denen korrespondierend das Gehäuse 10 außenseitig eine Ringnut 23 aufweist. In die Einsteckkanäle 24 ist eine Klammerfeder 25 eingesteckt, die mit ihren Federschenkeln in die Ringnut 23 des Gehäuses 10 eingreift, so daß die Überwurfbuchse 18 einerseits formschlüssig auf dem Gehäuse 10 gehalten, andererseits aber gegenüber dem Gehäuse 10 drehbar ist.The sleeve 18 is with the housing 10 positive, but rotatable relative to the housing 10 connected in that in the wall of Union sleeve two secant Insertion channels 24 are arranged, to which corresponding to the outside of the housing 10 Has annular groove 23. In the insertion channels 24 is one Clamp spring 25 inserted with their Spring legs in the annular groove 23 of the housing 10 engages so that the sleeve 18 on the one hand positively held on the housing 10, on the other hand but is rotatable relative to the housing 10.

Zur Begrenzung des möglichen Drehweges der Überwurfbuchse 18 gegenüber dem Gehäuse 10 im Hinblick auf die Festlegung der Entriegelungsstellung bzw. der Verriegelungsstellung der mit der Überwurfbuchse 18 fest verbundenen Verriegelungszunge 19 weist die Verriegelungszunge 19 einen in Richtung des stirnseitigen Endes des Gehäuses 10 vorspringenden Ansatz 21 auf, der in einen an der Stirnseite des Gehäuses 10 angeordneten Rücksprung 22 eingreift, wobei der Rücksprung sich über einen Teilumfang des Gehäuses 10 erstreckt und die Begrenzungskanten des Rücksprunges 22 die Anschläge für die Drehbewegung der Überwurfbuchse 18 mit Verriegelungszunge 19 bilden.To limit the possible rotation of the Union sleeve 18 with respect to the housing 10 in view on the determination of the unlocking position or Locked position with the sleeve 18 firmly connected locking tongue 19 has the Locking tongue 19 in the direction of projecting end face of the housing 10 Approach 21 on one in the front of the Housing 10 arranged recess 22 engages, wherein the recess extends over part of the circumference of the housing 10 extends and the boundary edges of the recess 22 the stops for the rotational movement of the Form union sleeve 18 with locking tongue 19.

In der in Figur 1 dargestellten Stellung mit eingestecktem Schlüssel 26 kann nun der Schließzylinder 13 durch Drehung in diejenige Stellung verbracht werden, in welcher der axiale Nutfortsatz 16 mit dem Stift 17 des Gehäuses fluchtet, so daß in dieser Stellung der Schließzylinder 13 aus dem Gehäusekanal 10 herausgezogen werden kann. Damit ist der Weg frei für das Einstecken einer nicht dargestellten Betätigung in dem Gehäusekanal 12 bis zum Eingriff der Betätigung in die Betätigungsöffnung 20 der Verriegelungszunge 19. Bei eingesteckter Betätigung kann somit die Verriegelungszunge 19 mit einem beliebigen Kraftaufwand gedreht werden. Nach Beendigung der entsprechenden Schließ- bzw. Öffnungsbewegung der Verriegelungszunge 19 wird die Betätigung aus dem Gehäusekanal 12 herausgezogen, und es wird anschließend wiederum der Schließzylinder 13 in den Gehäusekanal 12 eingeführt, wobei der Stift 17 zunächst in den axialen Nutfortsatz 16 eintritt, bis bei eingestecktem Schließzylinder 13 der Stift 17 in die radiale Nut 15 eintritt. In dieser Stellung kann der Schließzylinder 13 verdreht werden, wobei nun der Stift 17 durch Eingriff in die Nut 15 den Schließzylinder 13 festlegt, so daß der Schlüssel 26 abgezogen werden kann.In the position shown in Figure 1 with inserted key 26 can now the lock cylinder 13 brought into that position by rotation be in which the axial groove extension 16 with the Pin 17 of the housing is aligned, so that in this Position of the locking cylinder 13 from the housing channel 10 can be pulled out.
