Abstract

The rotary lock cylinder has a cylinder core (3) and a housing (1), hardened spring-loaded housing pins (4) and core pins (5) being mounted in radially extending bores. By means of a key to be inserted into the key channel (8), the tumbler pins (4, 5) are arranged so as to allow the rotation of the cylinder core (3). The cylinder core (3) has, in bores (10), pins (11) made of hardened steel which extend in the longitudinal direction of the cylinder core (3). The pins (11) are so arranged that, when a screw is screwed in, it is guided on the pins (11) and the core pins and housing pins (5, 4) are thereby pressed into the cylinder housing (1) to the extent of a spring block. When the screw is rotated further, the thread flights on the hardened tumbler pins (5) are peeled off. As a result of this measure, the screw has no hold in the cylinder and therefore cannot tear the cylinder or pull the core (3). <IMAGE>

Description

Drehschliesszylinder dieser Art sind allgemein bekannt und haben sich an sich bewährt und eine weite Verbreitung gefunden. Es ist nun eine Einbruchmethode bekannt geworden, bei welcher eine selbstschneidende und gehärtete Stahlschraube mit einem Durchmesser von etwa 4 mm und mit einem Sechskantkopf in den Zylinderkern eines solchen Drehschliesszylinders eingedreht wird. Mit einer Abziehvorrichtung beispielsweise gemäss der DE-OS 3 711 938 wird die eingedrehte Schraube zusammen mit dem Zylinderkern aus dem Zylindergehäuse gezogen und der nun freiliegende Mitnehmer mit einem Schraubenzieher gedreht und damit das Schloss geöffnet. Um diese Einbruchmethode zu verhindern, können am inneren Ende des Zylinderkerns Klauen angebracht und der Zylinderkern mit dem Mitnehmer ver­koppelt werden. Es hat sich jedoch gezeigt, dass infolge der ausserordentlich hohen Zugkraft der Abziehvorrichtung, auch ein solcher Zylinderkern ohne weiteres aus dem Zylin­dergehäuse gezogen werden kann. Wesentlich wirkungsvoller ist es, bei einem Drehschliesszylinder aus zusammengesetz­ten Zylinderteilen den Zylinderkern mit einem radial vor­stehenden Absatz an einem Ende zu versehen und diesen von hinten in die Gehäuseöffnung einzusetzten. Bei einem Doppel­schliesszylinder mit einem einteiligen Zylindergehäuse ist dies jedoch nicht möglich, da der Zylinderkern nur von vorne eingesetzt werden kann.Rotary lock cylinders of this type are generally known and have proven themselves and have found widespread use. A break-in method has now become known in which a self-tapping and hardened steel screw with a diameter of approximately 4 mm and with a hexagon head is screwed into the cylinder core of such a rotary lock cylinder. With a pulling device, for example according to DE-OS 3 711 938, the screwed-in screw is pulled out of the cylinder housing together with the cylinder core and the now exposed driver is rotated with a screwdriver and the lock is thus opened. To prevent this break-in method, claws can be attached to the inner end of the cylinder core and the cylinder core can be coupled to the driver. However, it has been shown that as a result the extraordinarily high tensile force of the puller, such a cylinder core can be easily pulled out of the cylinder housing. It is much more effective to provide the cylinder core with a radially projecting shoulder at one end in a rotary lock cylinder made up of assembled cylinder parts and to insert this from behind into the housing opening. However, this is not possible with a double lock cylinder with a one-piece cylinder housing, since the cylinder core can only be inserted from the front.

Der Erfindung liegt die Aufgabe zugrunde, einen Drehschliess­zylinder der genannten Gattung zu schaffen, bei dem die er­wähnte Einbruchmethode unwirksam ist und der dennoch funktions­tüchtig ist und kostengünstig hergestellt werden kann. Die Aufgabe wir durch die Erfindung gemäss Anspruch 1 gelöst. Beim erfindungsgemässen Drehschliesszylinder ist es wie anhin möglich, eine gehärtete Stahlschraube in den Zylinderkern einzudrehen. Hierbei wird jedoch der Gewindeteil der geführten Schraube durch die Stifte und/oder die Kernstifte abgeschert. Wird nun mit der Abziehvorrichtung an der Schraube gezogen, so findet diese im Zylinderkern keinen Halt und wird aus dieser herausgezogen, wobei der Zylinderkern im Gehäuse bleibt. Wird die Schraube zu nahe an den Kernstiften in den Zylinderkern eingedreht, so werden die Zuhaltungsstifte in ihren Bohrungen durch die Schraube radial nach aussen geschoben. Dies führt jedoch zu einer völligen Blockierung des Drehschliesszylinders, da die nach aussen getretenen Kernstifte den Zylinderkern im Zylinderge­häuse verankern. Wesentlich ist somit, dass die Stifte so an­geordnet sind, dass beim Eindrehen einer Schraube, die Schraube an diesen Stiften geführt wird und dadurch die Kern- und Ge­häusestifte in das Zylindergehäuse auf Block gedrückt werden. Beim Weiterdrehen der Schraube werden nun die Gewindekäse an den gehärteten Zuhaltungsstiften abgeschält. Durch diese Mass­nahme hat die Schraube keine Haltefestigkeit im Zylinder und kann deshalb den Zylinder nicht zerreissen oder den Kern nicht ziehen.The invention has for its object to provide a rotary lock cylinder of the type mentioned, in which the burglary method mentioned is ineffective and which is still functional and can be produced inexpensively. The object is achieved by the invention according to claim 1. With the rotary lock cylinder according to the invention, it is as possible possible to screw a hardened steel screw into the cylinder core. Here, however, the threaded part of the guided screw is sheared off by the pins and / or the core pins. If the pulling device is now pulled on the screw, there is no hold in the cylinder core and is pulled out of it, the cylinder core remaining in the housing. If the screw is screwed in too close to the core pins in the cylinder core, the tumbler pins in their holes are pushed radially outwards by the screw. However, this leads to a complete blocking of the rotary lock cylinder, since the Anchored outside core pins anchor the cylinder core in the cylinder housing. It is therefore essential that the pins are arranged in such a way that when a screw is screwed in, the screw is guided on these pins and the core and housing pins are thereby pressed onto the block in the cylinder housing. When the screw is turned further, the threaded cheese on the hardened tumbler pins is peeled off. As a result of this measure, the screw has no holding strength in the cylinder and therefore cannot tear the cylinder or pull the core.

Weist der Drehschliesszylinder mehrere Zuhaltungsreihen auf, wie dies bei Drehschliesszylindern für Flachschlüssel meist der Fall ist, so erstrecken sich die Stifte in Längsrichtung des Zylinderkerns, wobei je nach Anordnung der Zuhaltungsreihen zwei oder vier Stifte vorgesehen sind. Bei einem Drehschliesszylinder für einen sogenannten Zackenschlüssel sind die Stifte vorzugs­weise so in den Zylinderkern eingesetzt, dass sie senkrecht zur Längsachse des Zylinderkerns und parallel zu den Zuhaltungs­stiften verlaufen. Hierbei sind vorzugsweise mehrere Stiftpaare im Abstand zueinander angeordnet. Sind die Abstände zwischen den Stiftpaaren unterschiedlich, so wird die Sicherheit erhöht, dass beim Eindrehen der Schraube deren Gewindeteil durch die Stifte abgeschert wird. Bei lediglich zwei Stiften besteht das Risiko, dass diese den Gewindeteil der Schraube nicht verletzten, sondern im Gegenteil der Schraube zusätzlichen Halt geben. Selbst­verständlich scheitert ein Einbruchversuch auch dann, wenn die Schraube unter Vermeidung des Kontaktes mit den Stiften teil­weise in das Gehäuse eingedreht wird.If the rotary lock cylinder has several rows of tumblers, as is usually the case with rotary lock cylinders for flat keys, the pins extend in the longitudinal direction of the cylinder core, two or four pins being provided, depending on the arrangement of the tumbler rows. In a rotary lock cylinder for a so-called serrated key, the pins are preferably inserted into the cylinder core in such a way that they run perpendicular to the longitudinal axis of the cylinder core and parallel to the tumbler pins. Several pairs of pins are preferably arranged at a distance from one another. If the distances between the pairs of pins are different, the security is increased that when the screw is screwed in, its threaded part is sheared off by the pins. If there are only two pins, there is a risk that they will not damage the threaded part of the screw, but on the contrary give the screw additional hold. Of course, an attempted break-in also fails if the Screw is partially screwed into the housing while avoiding contact with the pins.

Die Weiterbildung nach den Ansprüchen 5 bis 9 verstärkt den Schliesszylinder im Bereich des Steges und verhindert zugleich, dass der Steg mit einem Bohrwerkzeug geschwächt und mit der genannten Einbruchmethode der Doppelzylinder auseinanderge­rissen wird. Kann der Doppelzylinder im Bereich der Stulp­schraube getrennt werden, so verhindern die im Zylinderge­häuse verankerten Stifte, dass der Steg des Zylinderteils am Langschild abgeschert und der Zylinderteil aus der Türe her­ausgezogen werden kann.The development according to claims 5 to 9 reinforces the locking cylinder in the area of the web and at the same time prevents the web from being weakened with a drilling tool and being torn apart with the aforementioned break-in method of the double cylinder. If the double cylinder can be separated in the area of the faceplate screw, the pins anchored in the cylinder housing prevent the bridge of the cylinder part from shearing off on the long plate and the cylinder part from being pulled out of the door.

Der in Fig. 1 gezeigte Drehschliesszylinder ist ein Doppel­zylinder mit zwei Zylindergehäusen 1, die mittels eines Steges 2 aus gehärtetem Stahl miteinander verbunden sind. Der Dreh­schliesszylinder kann jedoch auch ein einfacher Zylinder sein. Im Zylindergehäuse 1 ist in bekannter Weise ein Zylinderkern 3 drehbar gelagert, der einen Schlüsselkanal 8 aufweist, in den zur Betätigung des Schlosses ein hier nicht gezeigter Schlüssel eingesetzt wird. Mit dem Schlüssel werden die Zuhaltungs­reihen aus Kernstiften 5, Gehäusestiften 4, Federn 6 und Kammer­wänden 7 eingeordnet. Die Kernstifte 5 bestehen aus gehärtetem Stahl, während die Gehäusestifte 4 aus Messing bestehen können. Der gezeigte Drehschliesszylinder weist ein sogenantes Euro­profil auf, doch sind hier auch andere Profile möglich.The rotary lock cylinder shown in Fig. 1 is a double cylinder with two cylinder housings 1, which are connected to each other by means of a web 2 made of hardened steel. However, the rotary lock cylinder can also be a simple cylinder. In the cylinder housing 1, a cylinder core 3 is rotatably mounted in a known manner, which has a key channel 8, in which a key, not shown here, is used to actuate the lock. The tumbler rows of core pins 5, housing pins 4, springs 6 and chamber walls 7 are arranged with the key. The core pins 5 are made of hardened steel, while the housing pins 4 can be made of brass. The rotary lock cylinder shown has a so-called Euro profile, but other profiles are also possible here.

Der Zylinderkern 3 weist vier nach hinten offene Sackbohrungen 10 auf, die parallel zu seiner Rotationsachse verlaufen und in die Stifte 11 aus gehärtetem Stahl mit Festsitz eingesetzt sind. Die Stifte 11 weisen einen Durchmesser von etwa 2 mm auf und erstrecken sich etwa über die ganze Länge des Zylinderkerns 3. Wesentlich ist, dass bei der in Fig. 1 gezeigten Anordnung die beiden unteren Stifte 11 einen Abstand zueinander aufweisen, der kleiner als etwa 3,2 mm und vorzugsweise kleiner als 3,0 mm ist. Der Abstand B zwischen den genannten Stiften 11 und den nächstliegenden Kernstiften 5 ist vorzugsweise kleiner als etwa 0,6 mm. Bei dieser Anordnung wird beim Eindrehen einer Schraube in den Zylinderkern 3, an dieser der Gewindeteil durch die die Schraube führenden Stifte 11 und/oder die radial nach aussen ge­ schobenen Kernstifte 5 abgeschert, so dass der Zylinderkern 3 auch bei gut sitzender Schraube nicht aus dem Zylindergehäuse 1 herausgezogen werden kann.The cylinder core 3 has four blind bores 10 which are open to the rear and which run parallel to its axis of rotation and are inserted into the pins 11 made of hardened steel with a fixed fit. The pins 11 have a diameter of approximately 2 mm and extend approximately over the entire length of the cylinder core 3. It is essential that, in the arrangement shown in FIG. 1, the two lower pins 11 are at a distance from one another which is smaller than approximately 3 , 2 mm and preferably less than 3.0 mm. The distance B between said pins 11 and the closest core pins 5 is preferably less than about 0.6 mm. With this arrangement, when a screw is screwed into the cylinder core 3, the threaded part on the latter by the pins 11 guiding the screw and / or the radially outward position pushed core pins 5 sheared, so that the cylinder core 3 can not be pulled out of the cylinder housing 1 even when the screw is well seated.

Je nach Anzahl und Anordnung der Zuhaltungsreihen können zwei Stifte 11 genügen, in der Regel sind jedoch nicht mehr als vier Stifte 11 erforderlich.Depending on the number and arrangement of the tumbler rows, two pins 11 may suffice, but generally no more than four pins 11 are required.

Weist der Rotor wie in den Fig. 2 und 3 gezeigt lediglich eine Zuhaltungsreihe in einem Zylinderkern 12 mit profiliertem Schlüssekanal 13 auf, so können wie in Fig. 2 gezeigt auch mehrere Stifte 20 - 24 eingsetzt sein, die sich rechtwinklig zur Rotationsachse des Zylinderkerns 12 erstrecken. Die Stifte 20 bis 24 sind mit Festsitz in paarweise angeordnete Bohrungen 15 - 19 eingesetzt, die wie in Fig. 2 gezeigt, jeweils zwischen zwei Bohrungen 14 für die Zuhaltungsstifte angeordnet sind. Wesentlich ist auch hier, dass die Abstände zwischen je zwei zusammengehörigen Stiften 20 bis 24 kleiner als etwa 3,2 mm sind. Die Abstände können gleich oder wie in Fig. 2 gezeigt, können Abstände D und E unterschiedlich sein.If, as shown in FIGS. 2 and 3, the rotor has only one tumbler row in a cylinder core 12 with a profiled key channel 13, then, as shown in FIG. 2, a plurality of pins 20-24 can also be used, which are perpendicular to the axis of rotation of the cylinder core 12 extend. The pins 20 to 24 are inserted with a tight fit in bores 15-19 arranged in pairs which, as shown in FIG. 2, are each arranged between two bores 14 for the tumbler pins. It is also important here that the distances between two associated pins 20 to 24 are less than about 3.2 mm. The distances may be the same or, as shown in FIG. 2, distances D and E may be different.

Bei dem in den Figuren 4 und 5 gezeigten Doppelzylinder 40 sind zusätzlich in Bohrungen 31 eines Steges 30 gehärtete Stahl­stifte 32 eingesetzt, die ein Abscheren des aus Messing be­stehenden Steges 30 verhindern. Die Stifte 32 erstrecken sich innen bis ins Zylindergehäuse und stirnseitig bis nahe an die Mantelfläche des Zylinderkerns. Es sind beidseitig einer Gewindebohrung 34 bzw. des Mitnehmers 33 wenigstens je ein Stahlstift 32 angeordnet.In the double cylinder 40 shown in FIGS. 4 and 5, hardened steel pins 32 are additionally used in bores 31 of a web 30, which prevent the web 30 made of brass from shearing off. The pins 32 extend inside into the cylinder housing and on the end face up to close to the outer surface of the cylinder core. There is one on both sides Threaded bore 34 or the driver 33 each arranged at least one steel pin 32.

Aus den obigen Angaben ergeben sich somit Drehschliesszylinder, die trotz der erheblich höheren Schliesssicherheit nur un­wesentlich teurer sind als die üblichen Drehschliesszylinder, so dass erfindungsgemäss Drehschliesszylinder geschaffen wurden, die nicht nur den sicherheitstechnischen Anforderungen in her­vorrangender Weise Rechnung tragen, sondern aufgrund ihrer ein­fachen Ausführbarkeit kostenmässig günstig und zuverlässig sind.The above information thus results in rotary lock cylinders which, despite the considerably higher locking security, are only marginally more expensive than the conventional rotary lock cylinders, so that rotary lock cylinders according to the invention were created which not only take account of the safety requirements in an outstanding manner, but are also inexpensive due to their simple design and are reliable.

Wie leicht verständlich ist, können in Anpassungen an andere Zylindertypen Einzelheiten in verschiedener Weise abgewandelt werden. So kann insbesondere der Durchmesser der Stifte 11 und 20 bis 24 entsprechend der Grösse des Drehschliesszylinders auch grösser als 2 mm sein.As is easily understood, details can be modified in different ways in adaptations to other cylinder types. In particular, the diameter of the pins 11 and 20 to 24 can also be greater than 2 mm, depending on the size of the rotary lock cylinder.
