Abstract

The rotary lock cylinder has a cylinder core (1) which consists of a cylindrical body (11) with an open key guide and of at least one coaxial case (4) surrounding this. The case (4) closes the laterally open key guide, so that a virtually closed key channel (3) is formed. The case (4) is preferably movable and centres itself automatically. The movable case (4) also prevents opening attempts and thus increases the security value of the rotary lock cylinder. By changing the thickness of the wall of the case (4), it is possible to vary the radial distance between the key channel (3) and the outer surface of the cylinder core (1), with the result that the number of locking possibilities differing from one another can be increased in a constructionally simple way. <IMAGE>

Description

Die Erfindung betrifft einen Drehschliesszylinder nach dem Oberbegriff des unabhängigen Patentanspruchs 1. Ein Drehschliesszylinder dieser Art ist aus der DE-A-35 03 570 bekannt. Diese offenbart einen codierbaren Schliesszylinder mit wenigstens zwei Scherflächen oder Codierscheiben zur Umstellung des Schliesscodes. Da beim Umstellen des Schliesscodes die Scherflächen zwischen dem Rotorkern und der Rotorlage benutzt wird, ist der Schliesskanal dann nicht geschlossen, wenn weitere Zuhaltungsebenen (Zuhaltungsebene 35′) besetzt sind. Die Rotorlage schafft hier somit keinen vollständigen und in jedem Fall geschlossenen Schlüsselkanal. Damit die Rotorlage Codierelemente und eine Druckfeder aufnehmen kann, muss diese ein Stärke von wenigstens einem halben Zentimeter aufweisen. Ein solcher Schliesszylinder ist ersichtlich wesentlich aufwendiger in der Herstellung und entsprechend teurer als ein üblicher Schliesszylinder und besitzt auch besondere Aussenmasse.The invention relates to a rotary lock cylinder according to the preamble of independent claim 1. A rotary lock cylinder of this type is known from DE-A-35 03 570. This discloses a codable locking cylinder with at least two shear surfaces or coding disks for changing the locking code. Since the shearing surfaces between the rotor core and the rotor position are used when changing the locking code, the locking channel is not closed when further locking levels (locking level 35 ') are occupied. The rotor position therefore does not create a complete and, in any case, closed key channel. So that the rotor position can accommodate coding elements and a compression spring, it must have a thickness of at least half a centimeter. Such a locking cylinder is obviously much more complex to manufacture and correspondingly more expensive than a conventional locking cylinder and also has a special external dimension.

Der Erfindung liegt die Aufgabe zugrunde, einen Schliesszylinder zu schaffen, der die Vorteile eines innen geräumten, geschlossenen Schlüsselkanals aufweist, der jedoch wesentlich kostengünstiger und einfacher hergestellt werden kann.The invention has for its object to provide a lock cylinder which has the advantages of an internally cleared, closed key channel, but which can be manufactured much more cost-effectively and easily.

Beim Drehschliesszylinder nach dem neuen Patentanspruch 1 wird die äussere Rotorlage durch eine Hülse mit einer Wandstärke kleiner oder gleich 1 mm gebildet. Die Wandstärke ist hier somit so gering, dass der Aussendurchmesser des Rotors nicht grösser als üblich ist. Aenderungen am Zylindergehäuse sind beim erfindungsgemässen Drehschliesszylinder somit nicht erforderlich.In the rotary lock cylinder according to the new patent claim 1, the outer rotor position is formed by a sleeve with a wall thickness less than or equal to 1 mm. The wall thickness is so small here that the outside diameter of the rotor is not larger than usual. Changes to the cylinder housing are therefore not required in the rotary lock cylinder according to the invention.

Ebenfalls im Unterschied zum Stand der Technik besitzt der erfindungsgemässe Schliesszylinder nur eine einzige Scherfläche zwischen der Mantelfläche der Hülse und dem Zylindergehäuse. Der Schlüsselkanal ist hier somit in jedem Fall geschlossen und besitzt zumindest die Vorteile eines innen geräumten Schlüsselkanals.Also in contrast to the prior art, the lock cylinder according to the invention has only a single shear surface between the outer surface of the sleeve and the cylinder housing. The key channel is thus closed in any case and has at least the advantages of a key channel cleared inside.

Mit einer losen Hülse gemäss Alternative a) des Anspruchs 1 können zerstörungsfreie Oeffnungsmethoden verhindert werden. Mit der Erfindung ist es somit möglich, sehr kostengünstig bei einem üblichen Drehschliesszylinder einen geschlossenen Schlüsselkanal zu schaffen und gleichzeitig wichtige Oeffnungsmethoden zu verhindern.With a loose sleeve according to alternative a) of claim 1, non-destructive opening methods can be prevented. With the invention it is thus possible to create a closed key channel very inexpensively in a conventional rotary lock cylinder and at the same time to prevent important opening methods.

Gemäss der Alternative b) ist die Hülse fest und unverschiebbar mit dem Rotor verbunden. Dadurch wird mit konstruktiv besonders einfachen Mitteln ein Zylinderkern mit geschlossenem Schlüsselkanal geschaffen.According to alternative b), the sleeve is fixedly and immovably connected to the rotor. As a result, a cylinder core with a closed key channel is created with structurally particularly simple means.

Der zylindrische Körper des Zylinderkerns, der aus Messing bestehen kann, wird mit einem im Querschnitt nach aussen offenen Schlüsselkanal versehen. Der geschlitzte Kern wird nun durch Aufschieben einer geschlossenen Hülse am Umfang des Zylinderkerns überdeckt. Beim Drehen des Zylinderkerns gleiten die Gehäusestifte auf dieser geschlossenen Hülse und können unabhängig von der Ausbildung der Schlüsselkanäle oder durch die Abnutzung des Schlüssels nicht mehr in den Schlüsselkanal eingreifen und dadurch verklemmen.The cylindrical body of the cylinder core, which can consist of brass, is provided with a key channel that is open to the outside in cross section. The slotted core is now covered by sliding on a closed sleeve on the circumference of the cylinder core. When the cylinder core is rotated, the housing pins slide on this closed sleeve and, regardless of the design of the key channels or due to the wear of the key, can no longer engage in the key channel and thereby jam.

Es liegt damit ein quasi geschlossener Zylinderkern vor, der jedoch mit handelsüblichen Maschinen weit kostengünstiger hergestellt werden kann. Die Qualität und die Betriebssicherheit des erfindungsgemässen Zylinders sind gegenüber dem Stand der Technik wesentlich besser.There is thus a quasi-closed cylinder core, which, however, can be manufactured far more cost-effectively using commercially available machines. The quality and operational reliability of the cylinder according to the invention are significantly better than in the prior art.

Die Hülse kann nun fest mit dem Kern verbunden sein. Bei grossem Sicherheitswert wird die Hülse lose, frei schwimmend auf den Kern aufgesetzt. Beim Drehen des Rotors dreht auch die lose Hülse mit, da sie durch die durch die Hülse eingreifenden Kernstifte mitgezogen wird. Durch die Bewegung der Zuhaltungen wird die Hülse bei jeder Betätigung des Schliesszylinders selbsttätig zentriert.The sleeve can now be firmly connected to the core. If the safety value is high, the sleeve is placed loosely, freely floating on the core. When the rotor is rotated, the loose sleeve also rotates because it is pulled along by the core pins that engage through the sleeve. Due to the movement of the tumblers, the sleeve is automatically centered each time the locking cylinder is actuated.

Es hat sich gezeigt, dass der erfindungsgemässe Schliesszylinder die nachfolgend erläuterte Oeffnungsmethode mit Sicherheit verhindert.It has been shown that the locking cylinder according to the invention certainly prevents the opening method explained below.

Bei dieser Oeffnungsmethode werden sämtliche Zuhaltungsstifte radial nach aussen geschoben, d.h., man steckt einen unbearbeiteten Schlüsselrohling in die Schlüsselführung, der diese Arbeit problemlos ausführt. Nun fixiert man die nach aussen gedrückten Kern- und Gehäusestifte mit einem nicht genannten Mittel. Der Schlüsselrohling wird nun herausgezogen. Mit einem Schlüsselstumpf und durch leichtes Schlagen des Zylinderkerns in beide Drehrichtungen werden die Kern- und Gehäusestifte, die, z.B. unter Federdruck stehen, Schritt für Schritt nach innen bewegt. Bei jedem Schlag werden die Kernstifte ca. 1/100 mm vorwärts geschoben. Dieser Vorgang wird so lange durchgeführt, bis die Kernstifte das Gehäuse nicht mehr berühren. Der Kernstift läuft nur so lange vorwärts, solange er in der Gehäusebohrung anschlägt. Ist dies nicht mehr der Fall, ist der Kernstift vollständig in den Rotor eingetreten, d.h., auf Schliesshöhe.With this opening method, all tumbler pins are pushed radially outwards, ie you insert an unprocessed key blank into the key guide, which carries out this work without any problems. Now fix the pressed out core and housing pins with a means not mentioned. The key blank is now pulled out. With a key stump and light Hitting the cylinder core in both directions of rotation, the core and housing pins, which are under spring pressure, for example, are moved inwards step by step. With each stroke, the core pins are pushed forward approx. 1/100 mm. This process continues until the core pins no longer touch the housing. The core pin only runs forward as long as it strikes the housing bore. If this is no longer the case, the core pin has completely entered the rotor, ie at the closing height.

Dieser Vorgang wird nun fortgesetzt bis alle Kernstifte, die ja verschieden lang sind und deshalb auch verschiedene Zeiten beanspruchen, auf Schliesshöhe sind. Die Stifte können auf Schliesshöhe nochmals fixiert werden, womit sich der Zylinder über längere Zeit ohne Schlüssel öffnen und schliessen lässt. Diese Methode ist für alle Stiftzuhaltungs-Zylinderschlösser aber auch für Zylinderschlösser mit zwangsläufig gesteuerten Zuhaltungen ohne Federn anwendbar.This process is now continued until all core pins, which are of different lengths and therefore also take different times, are at the closing height. The pins can be fixed again at the closing height, so that the cylinder can be opened and closed for a long time without a key. This method can be used for all pin tumbler cylinder locks but also for cylinder locks with positively controlled tumblers without springs.

Bei einem erfindungsgemässen Schliesszylinder mit loser Hülse bleiben bei einem solchen unbefugten Oeffnungsversuch die Kernstifte erst dann stehen, wenn sie die lose Hülse passiert haben, d.h., erst wenn sie völlig im massiven Kern auf Schliesshöhe sind. Sobald aber der erste Gehäusestift die Scherfläche zwischen dem Zylindergehäuse und beweglicher Hülse überschritten hat, scheitert dieser unbefugte Oeffnungsversuch, da die Hülse durch einen bestimmten Kernstift gegen eine Verdrehung gesichert ist.In the case of a locking cylinder according to the invention with a loose sleeve, the core pins do not remain in such an unauthorized opening attempt until they have passed the loose sleeve, ie, only when they are completely in the solid core at the closing height. But as soon as the first housing pin the shear surface between the cylinder housing and more mobile If the sleeve has exceeded, this unauthorized attempt to open fails, since the sleeve is secured against rotation by a certain core pin.

Die geschlossene Hülse verhindert auch weitgehend eine Verschmutzung der Gehäusestifte und Federn. Beim offenen, geschlitzten Kern wird der in der Schlüsselführung angesammelte Staub und Schmutz mit der gefrästen oder geräumten Kante bei einer Kerndrehung transportiert und an den Bohrungsdurchbrüchen Kern/Gehäuse abgelagert. Durch die Bewegung der Kern- und Gehäusestifte werden diese Staubund Schmutzpartikel bis zu den Federn transportiert.The closed sleeve also largely prevents contamination of the housing pins and springs. In the case of the open, slotted core, the dust and dirt collected in the key guide is transported with the milled or cleared edge when the core is turned and deposited on the core / housing through-holes. By moving the core and housing pins, these dust and dirt particles are transported to the springs.

Durch die Weiterbildung nach Anspruch 2 wird erreicht, dass auch bei ausgezogenem Schlüssel, wenn also alle Kernstifte in den Kern eingetaucht sind, die bewegliche Hülse beim Drehen des zylindrischen kerns mitgezogen wird.The development according to claim 2 ensures that even when the key is pulled out, that is when all core pins are immersed in the core, the movable sleeve is pulled along when the cylindrical core is rotated.

Durch die Weiterbildung nach Anspruch 4 wird eine bedeutende Erhöhung der Anzahl voneinander abweichender Schliessungsmöglichkeiten in konstruktiv einfacher Weise realisiert.Through the development according to claim 4, a significant increase in the number of different locking options is realized in a structurally simple manner.

Der in den Fig. 1-3 gezeigte Schliesszylinder weist ein ruhendes, von einer koaxialen Hülse 5 umschlossenes Zylindergehäuse 2 und einen zentrisch oder exzentrisch in diesem gelagerten Zylinderkern 1 auf.The locking cylinder shown in FIGS. 1-3 has a stationary cylinder housing 2, which is enclosed by a coaxial sleeve 5, and a cylinder core 1, which is mounted centrically or eccentrically therein.

Die beiden Teile 1 und 2 enthalten radial oder nicht radial angeordnete Bohrungen 9, in denen mit oder ohne Federn 6 belastete Zuhaltungen aus z.B. je einem Kernstift 8 und einem Gehäusestift 7 gelagert sind. Die Zuhaltungen werden durch einen Schlüssel 13 eingeordnet, dessen Schaft eine Querschnittsform aufweist, die dem Querschnitt des Schlüsselkanals 3 entspricht.The two parts 1 and 2 contain radially or non-radially arranged bores 9, in which tumblers loaded with or without springs 6, for example each from a core pin 8 and a housing pin 7 are mounted. The tumblers are arranged by a key 13, the shaft of which has a cross-sectional shape that corresponds to the cross-section of the key channel 3.

Der Zylinderkern 1 weist einen zylindrischen Körper 11 auf, der von einer koaxialen, vorzugsweise losen Hülse 4 umschlossen ist. Die Hülse 4 kann ein axiales Spiel (X) aufweisen und zentriert sich selbst. Die Bohrungen 9, welche durch Gehäuse, Hülse, Kern bis zur Kernstiftbegrenzung stufenlos hindurchgehen, führen die Kern- und Gehäusestifte. Der zylindrische Körper 11 besteht vorzugsweise aus Messing oder Neusilber, während die Hülsen 4 fest oder lose aus einem anderen Material, z.B. aus gehärtetem Stahl bestehen können. Wie die Fig. 3 zeigt, greifen die eingeordneten, auf Schliesshöhe stehenden Kernstifte 8 in Bohrungen 9′ der Hülse 4 ein, so dass diese beim Drehen des zylindrischen Körpers 11 (Kern) mitgezogen wird. Die Scherfläche des Schliesszylinders befindet sich somit auf der Mantelfläche 10 der Hülse 4. Der Schlüsselkanal 3 wird durch den zylindrischen Körper 11 und durch die Hülse 4 im wesentlichen auf seiner ganzen Länge umschlossen, wobei der zylindrische Körper 11 einen von der Seite her eingefrästen Schlitz 3a (offener Kern) aufweist. Beim Drehen des Zylinderkerns 1 stehen die Gehäusestifte 7 an der Mantelfläche der Hülse 4 an und kommen weder mit dem eingesteckten Schlüssel 13 noch mit einer Kante des Schlüsselkanals 3 in Berührung. Die Gehäusestifte 7 können somit am Zylinderkern 11 auch nicht einhaken und werden entsprechend weniger abgenutzt, verkantet oder verformt, d.h., die Betriebssicherheit steigt beträchtlich.The cylinder core 1 has a cylindrical body 11 which is enclosed by a coaxial, preferably loose sleeve 4. The sleeve 4 can have an axial play (X) and centers itself. The bores 9, which continuously pass through the housing, sleeve, core to the core pin limit, guide the core and housing pins. The cylindrical body 11 is preferably made of brass or nickel silver, while the sleeves 4 can be fixed or loose from another material, for example hardened steel. As shown in Fig. 3, the arranged, standing at the closing core pins 8 in bores 9 'of the sleeve 4, so that this is pulled when turning the cylindrical body 11 (core). The shear surface of the locking cylinder is thus located on the outer surface 10 of the sleeve 4. The key channel 3 is enclosed by the cylindrical body 11 and by the sleeve 4 essentially over its entire length, the cylindrical body 11 having a slot 3a milled from the side (open core). When turning the cylinder core 1, the housing pins 7 are on the outer surface the sleeve 4 and come into contact neither with the inserted key 13 nor with an edge of the key channel 3. The housing pins 7 can therefore also not hook onto the cylinder core 11 and are correspondingly less worn, tilted or deformed, ie the operational safety increases considerably.

Die Hülse 4 sitzt vorzugsweise lose mit axialem Spiel auf dem Körper 11 oder, wie in Fig. 4 gezeigt, auf einer fest sitzenden Hülse 4a, so dass sie in Bezug auf diesen in Umfangsrichtung im Bereich des radialen Spiels der Zuhaltungsstifte 7 und 8 verschiebbar ist. Wird nun der Zylinderkern 11 bei einem unbefugten Oeffnungsversuch bewegt und dadurch die nach aussen geschobenen Zuhaltungsstifte nach innen verschoben, so bleiben die Kernstifte 8 nicht wie bisher nach ihrer Einordnung im Zylinderkern 1 stehen, sondern werden durch die sich relativ zum zylindrischen Körper 11 bewegende Hülse 4 weiter nach innen bis zur Trennlinie des festen Kerns getrieben, wobei die zugehörigen Gehäusestifte 7 den Schliesszylinder sofort sperren.The sleeve 4 preferably sits loosely with axial play on the body 11 or, as shown in FIG. 4, on a tightly fitting sleeve 4a, so that it can be displaced in relation to the latter in the circumferential direction in the region of the radial play of the tumbler pins 7 and 8 . If the cylinder core 11 is moved in the event of an unauthorized attempt to open it, and the tumbler pins pushed outwards are thereby moved inwards, the core pins 8 do not remain as they were previously in the cylinder core 1, but instead are moved by the sleeve 4, which moves relative to the cylindrical body 11 driven further inwards to the dividing line of the solid core, the associated housing pins 7 immediately locking the locking cylinder.

Wie in den Fig. 5a-d gezeigt, bestimmt die Wandung der Hülse 4 bzw. 4a die Lage des Schlüsselkanals 3, weil sich der Schlüsselrücken immer auf der Hülse 4 bzw. 4a abstützt. Durch die Wahl der Stärke der Hülse 4 bzw. 4a kann nun der Schlüsselkanal 3 je nach Zylindersystem senkrecht über den ganzen Kern 11 verschoben werden. Wird also bei gleichbleibendem Querschnitt der Schlüsselführung 3a und gleichem Aussendurchmesser des Zylinderkerns die Stärke der Hülse 4a variiert, so wird auch der radiale Abstand des Schlüsselkanals 3 von der Mantelfläche des Zylinderkerns 1 verändert, was zu einer bedeutenden Erhöhung der Anzahl voneinander abweichender Schliessungsmöglichkeiten führt.As shown in FIGS. 5a-d, the wall of the sleeve 4 or 4a determines the position of the key channel 3 because the key back is always supported on the sleeve 4 or 4a. By choosing the thickness of the sleeve 4 or 4a, the Key channel 3 can be moved vertically over the entire core 11, depending on the cylinder system. If the thickness of the sleeve 4a is varied while the cross-section of the key guide 3a remains the same and the outer diameter of the cylinder core is the same, the radial distance of the key channel 3 from the outer surface of the cylinder core 1 is also changed, which leads to a significant increase in the number of different locking options.

Da die Wandstärke der beweglichen Hülse sich zwischen 0,5-1 mm bewegen soll, wird bei stärkeren Hülsen eine feste, drehfest mit dem Kern 11 verbundene Hülse 4a und eine bewegliche Hülse 4 angeordnet. Die Hülse 4 kann aus einem Stück oder wie Fig. 6 zeigt, aus zwei durch einen schmalen Schlitz 12 von 0,2-0,3 mm voneinander getrennte Hälften 14a und 14b bestehen. Eine gehärtete Hülse 4 bietet einen ausgezeichneten Aufbohrschutz, da die Trennlinie zwischen Kern 11 und Gehäuse, die Verriegelungslinie sowie die Scherlinie auf der gesamten Länge geschützt sind.Since the wall thickness of the movable sleeve should move between 0.5-1 mm, in the case of thicker sleeves a fixed sleeve 4a, which is connected to the core 11 in a rotationally fixed manner, and a movable sleeve 4 are arranged. The sleeve 4 can consist of one piece or, as shown in FIG. 6, of two halves 14a and 14b separated by a narrow slot 12 of 0.2-0.3 mm. A hardened sleeve 4 offers excellent protection against drilling, since the dividing line between core 11 and housing, the locking line and the shear line are protected over the entire length.
