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. Bei diesen allgemein bekannten Drehschliesszylindern ist der Schlüssel­kanal im Zylinderkern im Querschnitt gesehen von aussen her aufgeschlitzt, man spricht vom offenen Schlüsselkanal. Ist ein Schlüssel nun auf einer oder beiden Hochkantseiten des Schaftes abgenutzt, was im Schliessanlagenbereich bei voll gebohrten Schlüsseln verhältnismässig oft vorkommt, so fal­len die Gehäusestifte beim Drehen des Zylinderkerns ent­sprechend der Abnutzung in den nicht mehr ausgefüllten Schlüsselkanal, d.h., die Gegenbolzen werden verkantet. Dies führt dazu, dass der Schliesszylinder klemmt und die Gehäusestifte bei jeder Betätigung abgenutzt werden sowie in ihrer Bohrung verklemmen oder sogar gekehrt werden, was den Zylinder funktionsunfähig macht. Um diese Nachteile zu vermeiden, sind bei hochwertigen Schliesszylindern die Schlüsselkanäle im Querschnitt geschlossen. Da jedoch das Ausräumen, Innenräumen solcher Schlüsselkanäle sehr auf­wendig und mit grossen Investitionen verbunden ist, sind diese Drehzylinderschlösser entsprechend teuer und werden deshalb nur sehr begrenzt eingesetzt.The invention relates to a rotary lock cylinder according to the preamble of independent claim 1. In these generally known rotary lock cylinders, the key channel in the cylinder core is cut open from the outside in cross section, one speaks of an open key channel. If a key is now worn on one or both upright sides of the shaft, which occurs relatively often in the locking system area with fully drilled keys, the housing pins fall into the key channel that is no longer filled when the cylinder core is rotated, i.e. the counter bolts are tilted. This causes the lock cylinder to jam and the housing pins to wear out with each actuation, jamming in their bore or even being swept, which renders the cylinder inoperable. To avoid these disadvantages, the key channels are closed in cross-section in high-quality locking cylinders. However, since that Removing, interior of such key channels is very complex and associated with large investments, these rotary cylinder locks are correspondingly expensive and are therefore used only to a very limited extent.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Schliesszylinder der eingangs genannten Gattung zu schaf­fen, der die oben aufgeführten Nachteile vermeidet. Der erfindungsgemässe Schliesszylinder soll die Vorteile eines innengeräumten, geschlossenen Schlüsselkanals aufweisen, jedoch in der Fabrikation wesentlich kostengünstiger und problemloser hergestellt werden können.The invention is therefore based on the object of providing a locking cylinder of the type mentioned at the outset which avoids the disadvantages listed above. The locking cylinder according to the invention is said to have the advantages of an internally cleared, closed key channel, but it can be manufactured much more cheaply and easily in production.

Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst.The object is achieved by the invention according to claim 1.

Der zylindrische Körperkern, 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 core, which can be made of brass, is provided with a key channel 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, since it is pulled along by the core pins engaging 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 bewegli­ cher 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 movable cher sleeve has failed, this unauthorized attempt to open fails because 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 Staub-­und 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. These dust and dirt particles are transported to the springs by the movement of the core and housing pins.

Durch die Weiterbildung nach Anspruch 2 wird erreicht, dass auch bei ausgewogenem 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 balanced, 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 5 wird eine bedeutende Erhöhung der Anzahl voneinander abweichender Schliessungs­möglichkeiten in konstruktiv einfacher Weise realisiert.Through the development according to claim 5, a significant increase in the number of different locking options is realized in a structurally simple manner.

  • 1 shows a cross section through a rotary lock cylinder according to the invention with the key pulled out,
  • 2 is a partial view of the rotary lock cylinder,

  • Fig. 6 shows a cross section through a further embodiment of a rotary lock cylinder according to the invention.

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 in this.

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 3 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 3, 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 die Bohrungen 12 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 Mantel­ fläche der Hülse 4 an und kommen weder mit dem eingesteck­ten Schlüssel 9 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 core pins 8, which are at the closing height, engage in the bores 12 of the sleeve 4, so that the latter is pulled along when the cylindrical body 11 (core) is rotated. 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 jacket surface of the sleeve 4 and come neither with the inserted key 9 nor with an edge of the key channel 3 in contact. 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 3a, 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 11a die Stärke der Hülse 4a variiert, so wird auch der radiale Abstand des Schlüsselkanals 3a 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 3a 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 11a is the same, the radial distance of the key channel 3a from the lateral 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 is to 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 from one another 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.
