Hierfür ist eine erste Baugruppe vorgesehen, welche das außenseitige Gehäuseteil und ein erstes Verbindungselement, insbesondere genau ein Verbindungselement, umfasst, welches mit dem außenseitigen Gehäuseteil verbunden ist und den Befestigungsabschnitt trägt. Diese Baugruppe wird erfindungsgemäß im Hinblick auf erhöhte Zugbelastungen ausgelegt, sodass vorzugsweise Ziehschutzwerte von 15 Kilonewton oder mehr erreicht werden. Da die erste Baugruppe den Befestigungsabschnitt für eine Stulpschraube umfasst, ist sichergestellt, dass bei einer Manipulation in das außenseitige Gehäuseteil eingeleitete Zugkräfte über das erste Verbindungselement bis hin zur Stulpschraube übertragen werden, ohne dass die erste Baugruppe versagt.According to the invention it is possible to provide a double lock cylinder on the outside with a pull protection function. For this purpose, a first assembly is provided which comprises the outside housing part and a first connection element, in particular exactly one connection element, which is connected to the outside housing part and carries the attachment portion. This assembly is designed according to the invention with regard to increased tensile loads, so that preferably pull protection values of 15 kilonewtons or more are achieved. Since the first assembly includes the fixing portion for a forend screw, it is ensured that in a tampering introduced into the outside housing part tensile forces are transmitted through the first connecting element to the forend screw without the first assembly fails.

Die zweite Baugruppe umfasst das innenseitige Gehäuseteil und mindestens ein zweites Verbindungselement zur Verbindung des ersten Verbindungselements mit dem innenseitigen Gehäuseteil. Diese zweite Baugruppe ist von einem Kraftfluss durch das außenseitige Gehäuseteil, das erste Verbindungselement und dessen Befestigungsabschnitt entkoppelt. Dies ermöglicht es, die zweite Baugruppe im Hinblick auf einen modularen Aufbau und im Hinblick auf eine komfortable und schnelle Montage der Bauteile der zweiten Baugruppe optimieren zu können.The second subassembly comprises the inside housing part and at least one second connecting element for connecting the first connecting element to the inside housing part. This second assembly is decoupled from a flow of force through the outside housing part, the first connection element and its attachment section. This allows the second assembly in the In view of a modular design and with a view to a comfortable and quick assembly of the components of the second module to optimize.

Insbesondere ist es bevorzugt, dass die Verbindungen zwischen den Bauteilen der ersten Baugruppe auf höhere Zugbelastungen ausgelegt sind als die Verbindungen zwischen den Bauteilen der zweiten Baugruppe.In particular, it is preferred that the connections between the components of the first assembly are designed for higher tensile loads than the connections between the components of the second assembly.

Beispielsweise ist zur Verbindung des ersten Verbindungselements und des außenseitigen Gehäuseteils eine Mehrstiftverbindung vorgesehen, während zur Verbindung des innenseitigen Gehäuseteils mit mindestens einem zweiten Verbindungselement eine Einfachstiftverbindung vorgesehen ist.For example, a multi-pin connection is provided for connecting the first connection element and the outside housing part, while a single-pin connection is provided for connecting the inside housing part to at least one second connection element.

Besonders stabile Verbindungen können bereitgestellt werden, wenn die Stiftverbindungen als Spiralstiftverbindungen ausgebildet sind.Particularly stable connections can be provided if the pin connections are designed as spiral pin connections.

Vorzugsweise ist die Verbindung zwischen dem ersten Verbindungselement und mindestens einem zweiten Verbindungselement als Schraubverbindung ausgebildet. Dies ermöglicht eine einfache Montage der Verbindungseinrichtung.Preferably, the connection between the first connecting element and at least one second connecting element is designed as a screw connection. This allows easy installation of the connecting device.

Besonders bevorzugt ist es, wenn die erste Baugruppe keine Schraubverbindungen zur Verbindung der Bauteile der ersten Baugruppe aufweist. Auf diese Weise können besonders hohe Ziehschutzwerte bereitgestellt werden.It is particularly preferred if the first module has no screw connections for connecting the components of the first module. In this way, particularly high pull-protection values can be provided.

Bevorzugt ist es ferner, wenn die für die Bauteile der ersten Baugruppe verwendeten Materialien eine höhere Festigkeit aufweisen, als die Materialien der Bauteile der zweiten Baugruppe. Auf diese Weise können außenseitig erhöhte Ziehschutzwerte bereitgestellt werden, während innenseitig einfachere und preisgünstigere Materialien verwendet werden können.It is further preferred if the materials used for the components of the first assembly have a higher strength than the materials of the components of the second assembly. In this way, higher pull-out protection values can be provided on the outside, while on the inside simpler and less expensive materials can be used.

Bevorzugt ist es ferner, wenn zumindest eine Teilmenge der Bauteile der ersten Baugruppe aus Materialien mit einer Festigkeitsklasse von 8.8 oder höher hergestellt sind.

In this way, pull protection values of 15 kilonewtons or higher can be provided.

Für den Fall, dass die erste Baugruppe eine Stulpschraube umfasst, ist diese vorzugweise aus einem Material mit einer Festigkeitsklasse von 12.9 oder höher hergestellt. Auf diese Weise ist sichergestellt, dass eine sich quer zu der Verbindungseinrichtung erstreckende Stulpschraube bei Beanspruchung der Verbindungseinrichtung auf Zug nicht abgeschert wird.In the event that the first assembly includes a forend screw, this is preferably made of a material with a strength class of 12.9 or higher. In this way, it is ensured that a forend screw extending transversely to the connecting device is not sheared off when the connecting device is subjected to tension.

Eine Ausführungsform eines Doppelschließzylinders ist in der Zeichnung insgesamt mit dem Bezugszeichen 10 bezeichnet. Der Doppelschließzylinder weist ein Zylindergehäuse 12 auf, in welchem ein Zylinderkern 14 aufgenommen ist.An embodiment of a double-locking cylinder is designated in the drawing as a whole by the reference numeral 10. The double lock cylinder has a Cylinder housing 12, in which a cylinder core 14 is received.

Das Zylindergehäuse weist ein innenseitiges Gehäuseteil 16 und ein außenseitiges Gehäuseteil 18 auf. Diese Gehäuseteile sind mittels einer insgesamt mit dem Bezugszeichen 20 bezeichneten Verbindungseinrichtung 20 miteinander verbunden.The cylinder housing has an inner-side housing part 16 and an outer-side housing part 18. These housing parts are connected to one another by means of a connecting device 20, designated overall by the reference numeral 20.

Die Verbindungseinrichtung 20 dient auch zur Verbindung des Doppelschließzylinders 10 mit einem nicht dargestellten Schlossgehäuse. Hierfür weist die Verbindungseinrichtung 20 einen Befestigungsabschnitt 22 in Form eines Innengewindes 24 auf. Der Befestigungsabschnitt 22 wirkt mit einer nicht dargestellten Stulpschraube zusammen, welche die Verbindungseinrichtung 20 und somit den Doppelschließzylinder 10 an oder in einem Einbauort fixiert.The connecting device 20 also serves to connect the double-locking cylinder 10 with a lock housing, not shown. For this purpose, the connecting device 20 has a fastening section 22 in the form of an internal thread 24. The attachment portion 22 cooperates with a not shown forend screw, which fixes the connecting device 20 and thus the double lock cylinder 10 at or in an installation location.

Der Doppelschließzylinder 10 weist eine erste Baugruppe 26 und eine zweite Baugruppe 28 auf. Die erste Baugruppe 26 ist der Schlossaußenseite zugeordnet und umfasst das außenseitige Gehäuseteil 18 sowie ein mit dem ersten Gehäuseteil 18 verbundenes erstes Verbindungselement 30, welches den Befestigungsabschnitt 22 trägt. Die zweite Baugruppe 28 ist der Schlossinnenseite zugeordnet und umfasst das innenseitige Gehäuseteil 16 sowie mindestens ein zweites Verbindungselement 32.
Die Verbindungselemente 30 und 32 sind Bestandteil der Verbindungseinrichtung 20 und untereinander mittels einer Schraubverbindung 34 miteinander verbunden.The double lock cylinder 10 has a first assembly 26 and a second assembly 28. The first module 26 is assigned to the outside of the lock and comprises the outside housing part 18 and a first connecting element 30 which is connected to the first housing part 18 and which carries the fastening section 22. The second module 28 is assigned to the inside of the lock and includes the inside housing part 16 and at least one second connecting element 32nd
The connecting elements 30 and 32 are part of the connecting device 20 and interconnected by means of a screw 34.

Zur Verbindung der Verbindungselemente 30, 32 mit den jeweiligen Gehäuseteilen 16, 18 sind Stiftverbindungen vorgesehen, welche insbesondere als Spiralstiftverbindungen 36 ausgebildet sind. Diese Spiralstiftverbindungen 36 umfassen Spiralstifte 38, welche entlang eines Teils ihrer Länge mit einem jeweiligen Gehäuseteil 16, 18 zusammenwirken und mit einem anderen Teil ihrer Länge mit Durchbrechungen oder Ausnehmungen der Verbindungselemente 30, 32.For connecting the connecting elements 30, 32 with the respective housing parts 16, 18 pin connections are provided, which are in particular designed as spiral pin connections 36. These spiral pin connections 36 comprise spiral pins 38, which cooperate along a part of their length with a respective housing part 16, 18 and with another part of their length with openings or recesses of the connecting elements 30, 32nd

Die erste Baugruppe 26 umfasst eine Mehrstiftverbindung 40 (insbesondere eine Doppelstiftverbindung), während die zweite Baugruppe 28 als Einfachstiftverbindung 42 ausgebildet ist. Dies hat, gleiche Größe und gleiches Material aller Spiralstifte 38 vorausgesetzt, zur Folge, dass die mechanische Verbindung zwischen dem äußeren Gehäuseteil 18 und dem ersten Verbindungselement 30 um den Faktor "2" stabiler ist als die mechanische Verbindung zwischen dem inneren Gehäuseteil 16 und dem zweiten Verbindungselement 32.The first assembly 26 comprises a multi-pin connection 40 (in particular a double-pin connection), while the second assembly 28 is designed as a single-pin connection 42. This has, same size and same material of all spiral pins 38 provided, with the result that the mechanical connection between the outer housing part 18 and the first connecting element 30 by a factor of "2" is more stable than the mechanical connection between the inner housing part 16 and the second Connecting element 32.

Zur weiteren Verbesserung der Stabilität der ersten Baugruppe 26 kann vorgesehen sein, dass das erste Verbindungselement 30 aus einem hochfesten Stahlmaterial, beispielsweise aus einem Vergütungsstahl, insbesondere aus 42CrMo4 mit einer Festigkeitsklasse von 8.8, oder aus einem vergleichbaren Werkstoff mit gleicher Festigkeitsklasse hergestellt ist. Das zweite Verbindungselement 32 kann aus einem weicheren Metall mit einer niedrigeren Festigkeitsklasse hergestellt sein.To further improve the stability of the first assembly 26, it may be provided that the first connection element 30 is made of a high-strength steel material, for example of a tempered steel, in particular of 42CrMo4 with a strength class of 8.8, or of a comparable material with the same strength class. The second connector 32 may be made of a softer metal of lower strength class.

Ein weiterer Unterschied zwischen den Baugruppen 26 und 28 besteht darin, dass das außenseitige Gehäuseteil 18 mit einem Bohrschutz 44 versehen ist. Ein entsprechender Bohrschutz ist auf der Innenseite des Gehäuses 12, also an dem innenseitigen Gehäuseteil 16, nicht vorgesehen.Another difference between the assemblies 26 and 28 is that the outer-side housing part 18 is provided with a Bohrschutz 44. A corresponding drill protection is not provided on the inside of the housing 12, that is to say on the inside housing part 16.

Die vorstehend beschriebenen Maßnahmen zur Erhöhung der Stabilität der ersten Baugruppe 26 haben zur Folge, dass ein auf der Schlossaußenseite ein hochwirksamer Ziehschutz bereitgestellt werden kann. Für den Fall, dass das Gehäuseteil 18 gewaltsam aus einem Einbauort entfernt werden soll, wirken an dem Gehäuseteil 18 Zugkräfte, welche über die Mehrstiftverbindung 40 auf das erste Verbindungselement 30 und auf den Befestigungsabschnitt 22 in eine Stulpschraube übertragen werden. Dieser Kraftfluss ist von der zweiten Baugruppe 28 entkoppelt. Die Innenseite des Doppelschließzylinders 10 kann daher aus Bauteilen mit schwächeren Materialien hergestellt sein, welche ihrerseits auch mit schwächeren Verbindungen untereinander verbunden sind.The measures described above for increasing the stability of the first assembly 26 have the result that a highly effective pulling protection can be provided on the outside of the lock. In the event that the housing part 18 is to be forcibly removed from an installation location, tensile forces act on the housing part 18 which are transmitted via the multi-pin connection 40 to the first connection element 30 and to the attachment section 22 in a forend screw. This power flow is decoupled from the second module 28. The inside Therefore, the double-lock cylinder 10 can be made of components with weaker materials, which in turn are interconnected with weaker connections.

Es ist möglich, dass die zweite Baugruppe 28 lediglich ein einziges zweites Verbindungselement 32 umfasst. Bei einer bevorzugten Ausführungsform, welche nachfolgend unter Bezugnahme auf Figuren 3 bis 7 beschrieben ist, sind jedoch zwei zweite Verbindungselemente 32 vorgesehen, die in Figur 3 mit 32a und 32b bezeichnet sind.It is possible that the second assembly 28 comprises only a single second connection element 32. In a preferred embodiment, which will be described below with reference to FIGS. 3 to 7 is described, however, two second connecting elements 32 are provided which in FIG. 3 are designated 32a and 32b.

Die Verbindungselemente 30, 32a, 32b der Verbindungseinrichtung 20 sind jeweils untereinander miteinander verbunden, insbesondere mittels einer Schraubverbindung 34.The connecting elements 30, 32a, 32b of the connecting device 20 are each connected to each other, in particular by means of a screw 34th

Ein erstes zweites Verbindungselement 32a, welches mit dem ersten Verbindungselement 30 verbunden ist, dient als Distanzelement, um zwischen dem Befestigungsabschnitt 22 und dem Gehäuseteil 16 einen vergrößerten Abstand bereitzustellen.
Ein zweites zweites Verbindungselement 32b, welches mit dem ersten zweiten Verbindungselement 32a verbunden ist, dient zur Verbindung der Verbindungseinrichtung 20 mit dem ersten Gehäuseteil 16.A first second connection element 32a, which is connected to the first connection element 30, serves as a spacer element in order to provide an increased distance between the attachment section 22 and the housing part 16.
A second second connection element 32b, which is connected to the first second connection element 32a, serves to connect the connection device 20 to the first housing part 16.

Durch Austausch des ersten zweiten Verbindungselements 32a durch ein erstes zweites Verbindungselement 32a mit abweichender Länge oder auch durch Hinzufügen eines weiteren zweiten Verbindungselements kann ein veränderter Abstand zwischen den innenseitigen Gehäuseteil 16 und dem Befestigungsabschnitt 22 eingestellt werden. Somit kann in modularer Weise ein Doppelschließzylinder 10 mit unterschiedlichen Axiallängen bereitgestellt werden.By replacing the first second connecting element 32a by a first second connecting element 32a with a different length or by adding a further second connecting element, a changed distance between the inside housing part 16 and the mounting portion 22 can be adjusted. Thus, a double lock cylinder 10 having different axial lengths can be provided in a modular manner.

Das erste Verbindungselement 30 erstreckt sich entlang einer Verbindungselementachse 46 und weist auf Höhe des Befestigungsabschnitts 22 eine Verdickung 48 auf.The first connecting element 30 extends along a connecting element axis 46 and has a thickening 48 at the level of the fastening section 22.

Das erste Verbindungselement 30 weist ferner auf seiner dem außenseitigen Gehäuseteil 18 zugewandten Seite zwei Bohrungen 50 zum Durchtritt der Spiralstifte 38 (vergleiche Figur 1) auf.The first connecting element 30 further has, on its side facing the outside housing part 18, two bores 50 for the passage of the spiral pins 38 (cf. FIG. 1 ) on.

Auf seiner dem innenseitigen Gehäuseteil 16 zugewandten Seite weist das erste Verbindungselement 30 ein Innengewinde 52 auf, welches Teil der Schraubverbindung 34 mit dem ersten zweiten Verbindungselement 32a ist. Dementsprechend weist das erste zweite Verbindungselement 32a auf seiner dem ersten Verbindungselement 30 zugewandten Seite ein Außengewinde 54 auf.On its side facing the inside housing part 16, the first connecting element 30 has an internal thread 52, which is part of the screw connection 34 with the first second connecting element 32a. Accordingly, the first second connecting element 32a has an external thread 54 on its side facing the first connecting element 30.

Das erste zweite Verbindungselement 32a weist auf seiner dem zweiten zweiten Verbindungselement 32b zugewandten Seite ein Innengewinde 56 auf, welches mit einem Außengewinde 58 des zweiten zweiten Verbindungselements 32b zusammenwirkt und eine Schraubverbindung 34 bildet.The first second connecting element 32a has, on its side facing the second second connecting element 32b, an internal thread 56 which cooperates with an external thread 58 of the second second connecting element 32b and forms a screw connection 34.

Das zweite zweite Verbindungselement 32b weist ferner eine um eine Elementachse 60 herum verlaufende Auskehlung 62 auf, welche mit einer Außenseite des Spiralstifts zusammenwirkt (vergleiche Figur 1).The second second connection element 32b further has a groove 62 extending around an element axis 60, which groove cooperates with an outer side of the spiral pin (cf. FIG. 1 ).
