Sur la goupille centrale (10) est disposée une douille coulissante (1), ayant une forme correspondante à celle dudit perçage a gradins (17b). L'arrêt d'après l'invention (10) peut être inséré dans les serrures cylindriques courantes et empêche de manière efficace une ouverture non autorisé, ouverture essayée sans clé et sans détériorer les serrures.The stop (10, 15), subjected to the load of a spring, has a housing pin (15) and a central pin (10). The latter pin has a limited stroke towards the key channel (14), being arranged in a stepped bore (17b) of the cylindrical core (13). On the central pin (10) is disposed a sliding sleeve (1), having a shape corresponding to that of said stepped bore (17b). The stop according to the invention (10) can be inserted into standard cylindrical locks and effectively prevents unauthorized opening, attempted opening without a key and without damaging the locks.

Description

Zuhaltung in einem Drehzylinderschloss Guard locking in a rotary cylinder lock
Die Erfindung betrifft eine Zuhaltung nach dem Oberbegriff des unabhängigen Patentanspruchs 1.The invention relates to a tumbler according to the preamble of independent claim 1.
Drehzylinderschlösser mit zweiteiligen Zuhaltungen sind allgemein bekannt und besitzen einen hohen Sicherheitswert. Es sind nun aber Oeffnungsmethoden entwickelt worden, mit denen diese Drehzylinderschlösser ohne Schlüssel und ohne äussere Beschädigungen an den Schlössern geöffnet werden können.Rotary cylinder locks with two-part tumblers are generally known and have a high security value. However, opening methods have now been developed with which these rotary cylinder locks can be opened without a key and without external damage to the locks.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Drehzylin¬ derschloss der genannten Art zu schaffen, das mit diesen Methoden nicht geöffnet werden kann.The invention is based on the object of creating a rotary cylinder lock of the type mentioned which cannot be opened using these methods.
Die Aufgabe wird erfindungsgemäss nach dem Kennzeichen des Patentanspruchs 1 gelöst. Der wirksame Teil der Zuhaltung bleibt bei den genannten Oeffnungsmethoden immer beweglich und kann deshalb nicht ausgemessen werden. Ebenso scheitern Oeffnungsmethoden die mit Hilfe von Andrückversuchen ar¬ beiten, da auch hier der wirksame Teil des Kernstifts nicht fixierbar ist. Die erfindungsgemässe Zuhaltung kann in einfacher Weise serienmässig hergestellt werden. Aenderungen an den übri¬ gen Teilen des Drehzylinderschlosses sowie am Schlüssel sind nicht erforderlich. Es genügt, dass in einem Drehzy¬ linderschloss neben den üblichen Zuhaltungen wenigstens eine erfindungsgemässe Zuhaltung eingesetzt ist, um dieses auch gegen die genannten Oeffnungsmethoden sicher zu ma¬ chen.The object is achieved according to the characterizing part of patent claim 1. With the opening methods mentioned, the effective part of the guard locking always remains flexible and therefore cannot be measured. Opening methods which work with the aid of pressure attempts likewise fail, since here too the effective part of the core pin cannot be fixed. The tumbler according to the invention can be mass-produced in a simple manner. Changes to the remaining parts of the rotary cylinder lock and to the key are not necessary. It is sufficient that in addition to the usual tumblers, at least one tumbler according to the invention is used in a rotary cylinder lock in order to also make it secure against the opening methods mentioned.
Durch die Fertigung der Spitze des Kernstifts als separa¬ ter Teil und die Befestigung der Spitze mit Festsitz am Stiftkörper wird es möglich, die Spitze aus einem Werkstoff herzustellen, der besonders aufbohrsicher ist. Ist die Spitze aus einem Hartmetallwerkstoff, wird zudem die Ab¬ nutzung der Spitze durch den Gebrauch weitgehend vermie¬ den.By manufacturing the tip of the core pin as a separate part and attaching the tip with a tight fit to the pin body, it is possible to manufacture the tip from a material that is particularly resistant to drilling. If the tip is made of a hard metal material, the use of the tip is also largely avoided.
Die Ausbildung der Zuhaltung nach Anspruch 5 verhindert zu¬ sätzlich auch Oeffnungsmethoden, bei denen die Kern- und Gehäusestifte getrennt werden, so dass der Rotor kurzzeitig gedreht werden kann.The formation of the tumbler according to claim 5 also prevents opening methods in which the core and housing pins are separated so that the rotor can be rotated briefly.
Weitere vorteilhafte Ausbildungen gehen aus den abhängigen Ansprüchen hervor. Ausführungsbeispiele der Erfindung werden nachfolgend an¬ hand der Zeichnung näher erläutert. Es zeigen:Further advantageous designs emerge from the dependent claims. Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:

Der in Fig. 2 dargestellte Schlosszylinder weist in bekann¬ ter Weise ein ruhendes Zylindergehäuse 12 auf, das in einer zylindrischen Hülse 11 steckt und in dem drehbar ein Zylin¬ derkern 13 angeordnet ist. Das Zylindergehäuse 12 und der Zylinderkern 13 weisen radiale Bohrungen 17a und 17b auf, in denen federbelastete Zuhaltungen verschiebbar gelagert sind. In jeder Gehäusebohrung 17a befindet sich eine Fe¬ der 16, die sich gegen die Hülse 11 abstützt und mit Vor¬ spannung auf einen Gehäusestift 15 drückt, welcher seiner¬ seits einen Kernstift 10 radial nach innen gegen einen in den Schlüsselkanal 14 einzuführenden Schlüssel drückt. Wie die Fig. 1 zeigt, weist der Kernstift 10 eine SpitzeThe lock cylinder shown in FIG. 2 has, in a known manner, a stationary cylinder housing 12, which is inserted in a cylindrical sleeve 11 and in which a cylinder core 13 is rotatably arranged. The cylinder housing 12 and the cylinder core 13 have radial bores 17a and 17b, in which spring-loaded tumblers are slidably mounted. In each housing bore 17a there is a spring 16, which is supported against the sleeve 11 and presses with pretension on a housing pin 15, which in turn presses a core pin 10 radially inward against a key to be inserted into the key channel 14. 1 shows, the core pin 10 has a tip
3 mit einem Verbindungsteil 3a und einem Kopf 3b mit ei¬ ner Steuerfläche auf. Der Kopf 3b kann jedoch auch mehrere Steuerflächen aufweisen, wodurch in bekannter Weise eine Erhöhung der Schliessungsmöglichkeiten erzielt werden kann. Die Spitze 3 besteht vorzugsweise aus einem Hartmetall¬ werkstoff oder einem anderen aufbohrsicheren und abriebfesten Hartstoff und ist mit Festsitz in einer Bohrung 7 im Stift¬ körper 5 befestigt.3 with a connecting part 3a and a head 3b with a control surface. However, the head 3b can also have a plurality of control surfaces, as a result of which the closing options can be increased in a known manner. The tip 3 preferably consists of a hard metal material or another hard-wearing and abrasion-resistant hard material and is fixed in place in a bore 7 in the pin body 5.
Auf dem Körper 5 ist ein hülsenförmiges Schiebeelement 1 verschiebbar gelagert. Sowohl das Schiebeelement 1 als • auch der Körper 5 sind am äusseren Ende im Durchmes¬ ser stufenförmig abgesetzt, so dass das Schiebeelement 1 nach aussen anschlagbegrenzt verschiebbar ist und einen breiteren Hülsenteil la und einen schmaleren Hülsenteil lb aufweist. Nach innen erfährt das Schiebeelement 1 am Hül¬ senteil lb durch den radial nach aussen vorstehenden Kopf 3b einen Anschlag.On the body 5, a sleeve-shaped sliding element 1 is slidably mounted. Both the sliding element 1 and the body 5 are stepped at the outer end in diameter, so that the sliding element 1 can be displaced outward with limited stops and has a wider sleeve part 1 a and a narrower sleeve part 1 b. Inwardly, the sliding element 1 on the sleeve part 1b experiences a stop through the radially outward projecting head 3b.
In den Fig. 3a und 3b ist ein Kernstift 30 dargestellt, der neben dem Schiebeelement 1 zusätzlich noch einen Sperr¬ stift 24 aufweist. Dieser ist in einer Stufenbohrung 27 im Stiftkörper 26 nach aussen anschlagbegrenzt gelagert. In der Stufenbohrung 27 befindet sich eine Druckfeder 25, die sich gegen die Spitze 3 abstützt und mit Vorspannung auf den Sperrstift 24 drückt, der am äusseren Ende am Gehäuse¬ stift 15 anliegt. Die Spannung der Feder 25 ist so gewählt, dass der Gehäusestift 15 vom Sperrstift 24 nicht aus sei¬ ner den Zylinder verriegelnden Lage bewegt wird. Die Fe¬ der 24 weist jedoch in der in Fig. 3a gezeigten Lage eine so grosse Spannung auf, dass der Sperrstift 24 dem Gehäu¬ sestift 15 im wesentlichen verzögerungsfrei folgt, wenn beide Stifte voneinander getrennt werden. Die Wirkungsweise des Sperrstifts 24 zeigt schematisch die Fig. 3b. Der Gehäusestift 15 ist hier durch eine be¬ kannte Oeffnungsmethode kurzzeitig in eine entriegelte La¬ ge bewegt worden, wobei der Kernstift 30 in seiner ur¬ sprünglichen Stellung verharrt. Der Zylinderkern 13 kann aber trotzdem nicht gedreht werden, da der Sperrstift 24 über die Scherfläche 32 hinausragt und den Drehzylinder verriegelt.3a and 3b, a core pin 30 is shown, which in addition to the sliding element 1 also has a locking pin 24. This is mounted in a stepped bore 27 in the pin body 26 to the outside with limited stops. In there is a compression spring 25 in the stepped bore 27, which is supported against the tip 3 and presses with pretension on the locking pin 24 which bears against the housing pin 15 at the outer end. The tension of the spring 25 is selected so that the housing pin 15 is not moved by the locking pin 24 from its position locking the cylinder. In the position shown in FIG. 3a, however, the spring 24 has such a great tension that the locking pin 24 follows the housing pin 15 essentially without delay if the two pins are separated from one another. The operation of the locking pin 24 is shown schematically in Fig. 3b. The housing pin 15 has been briefly moved into an unlocked position by a known opening method, the core pin 30 remaining in its original position. The cylinder core 13 can still not be rotated because the locking pin 24 protrudes beyond the shear surface 32 and locks the rotary cylinder.
Die Kernstifte 10 und 30 können in die üblichen Stufenboh¬ rungen 17b im Zylinderkern 13 eingesetzt werden. Durch die stufenförmige Ausbildung der Bohrung 17b und eine ent¬ sprechenden stufenförmige Ausbildung des Schiebeelements 1 ist die Verschiebbarkeit des Schiebeelements 1 und des ganzen Kernstifts 10 bzw. 30 zum Schlüsselkanal 14 hin be¬ grenzt. Der Kernstift kann auch wie in Fig. 4 dargestellt ausge¬ bildet sein. Bei diesem Kernstift 43 ist der Körper aus ei¬ nem Stück gefertigt und weist einen zylindrischen Schaft 41 sowie einen Kopf 40 mit einer etwa halbkugelförmigen Steuerfläche auf. Auf dem Schaft 41 ist ein zylindrisches Schiebeelement 42 verschiebbar gelagert, wobei das Schiebe¬ element 42 etwas kürzer ist als der Schaft 41. Bei einer Verschiebung in axiale Richtung erfährt das hülsenförmige Schiebeelement 42 nach innen einen Anschlag am Kopf 40 und nach aussen einen Anschlag am hier nicht gezeigten Gehäuse¬ stift 15, der wie beschrieben ausgebildet ist. Der Kern¬ stift .43 ist in seiner Herstellung besonders kostengünstig und eignet sich insbesondere für ein Drehzylinderschloss mit einem Zackenschlüssel.The core pins 10 and 30 can be inserted into the usual stepped bores 17b in the cylinder core 13. Due to the step-like design of the bore 17b and a corresponding step-like design of the sliding element 1, the displaceability of the sliding element 1 and of the entire core pin 10 or 30 towards the key channel 14 is limited. The core pin can also be designed as shown in FIG. 4. In this core pin 43, the body is made from one piece and has a cylindrical shaft 41 and a head 40 with an approximately hemispherical control surface. A cylindrical sliding element 42 is displaceably mounted on the shaft 41, the sliding element 42 being somewhat shorter than the shaft 41. When displaced in the axial direction, the sleeve-shaped sliding element 42 experiences a stop on the head 40 on the inside and a stop on the outside Housing pin 15, not shown here, which is designed as described. The .43 core pin is particularly inexpensive to manufacture and is particularly suitable for a rotary cylinder lock with a wrench.
Die oben beschriebenen Kernstifte 10, 30 und 43 weisen zwischen dem Schiebeelement 1 bzw. 42 und dem Kopf 3 bzw. 43 eine ringförmige Lücke 18 bzw. 48 auf. Diese sind, in Längsrichtung des Kernstifts gesehen, etwa 0,4 mm breit. In den Lücken 18 bzw. 48 kann eine nicht dargestellte Druck¬ feder angeordnet werden, welche das Schiebeelement 1 an die Schulter des Stiftkörpers 5 bzw. das Schiebeelement 42 an dan Gehäusestift 15 drückt. Die Spannung dieser Druckfeder ist vergleichsweise klein, stellt aber sicher, dass die Lücke 18 erhalten bleibt, wenn der Kernstift 10, 30 bzw. 43 nach aussen geschoben wird. Bei der Ausführung nach Fig. 4 hat diese Druckfeder den weiteren Vorteil, dass hier das Schiebeelement 42 auch die Wirkungsweise des Sperrstifts 24 übernimmt. Das Schiebeelement 42 und die Druckfeder ver¬ hindern somit wirksam, dass das Schloss durch Separierung von Kern- und Gehäusestift geöffnet werden kann und gleich¬ zeitig auch, dass der wirksame Teil des Kernstifts bei An¬ drück- und Aus essversuchen immer beweglich bleibt.The core pins 10, 30 and 43 described above have an annular gap 18 and 48 between the sliding element 1 and 42 and the head 3 and 43, respectively. Seen in the longitudinal direction of the core pin, these are about 0.4 mm wide. In the gaps 18 and 48, a compression spring (not shown) can be arranged, which presses the sliding element 1 against the shoulder of the pin body 5 or the sliding element 42 against the housing pin 15. The tension of this compression spring is comparatively small, but ensures that the gap 18 is retained when the core pin 10, 30 or 43 is pushed outwards. In the embodiment according to FIG. 4, this compression spring has the further advantage that here the sliding element 42 also takes over the mode of operation of the locking pin 24. The sliding element 42 and the compression spring thus effectively prevent the lock from being opened by separating the core and housing pins and, at the same time, also prevent the effective part of the core pin from remaining movable during attempts to press on and out.
Die erfindungsgemässe Zuhaltung arbeitet bei befugtem Oeff- nen mit dem vorgesehenen Schlüssel in gleicher Weise wie eine übliche Zuhaltung. When the opening is authorized, the guard locking device according to the invention works in the same way as a conventional locking device with the key provided.
