Description

Die Erfindung betrifft einen Doppelschliesszylinder für ein Sicherheitsschloss, nach dem Oberbegriff des Anspruchs 1.The invention relates to a double lock cylinder for a security lock, according to the preamble of claim 1.

Ein Schliesszylinder dieser Art ist im Stand der Technik aus der CH-A-674 542 bekannt. Bei diesem weist der türaussenseitige Zylinderkern an seiner Rückseite eine Verdikkung auf, was ein Ausreissen des Zylinderkerns wesentlich erschwert. Bei einem solchen Ausreissversuch wird in den türaussenseitigen Zylinderkern eine selbstschneidende Stahlschraube eingedreht und mit einer an dieser Schraube angesetzten Abziehvorrichtung sehr hohe Zugkräfte auf den Zylinderkern ausgeübt. A locking cylinder of this type is state of the art known from CH-A-674 542. In this case, the outside of the door Cylinder core on its back a thickening on what an essential pulling out of the cylinder core difficult. With such an attempt to pull out, the a self-tapping cylinder core on the outside Steel screw turned in and with one on this screw attached puller very high tensile forces on the Cylinder core exercised.

Der Erfinder hat sich die Aufgabe gestellt, einen Schliesszylinder der genannten Art zu schaffen, dessen Zugfestigkeit individuell festlegbar ist und damit unterschiedlichen Sicherheitsanforderungen entsprochen werden kann. Der Schliesszylinder soll insbesondere auch höheren Sicherheitsanforderungen bezüglich der Zugfestigkeit genügen.The inventor has set himself the task of To create lock cylinder of the type mentioned, its tensile strength is individually definable and therefore different Security requirements are met can. The lock cylinder should in particular also be higher Safety requirements with regard to tensile strength are sufficient.

Die Aufgabe ist bei einem gattungsgemässen Schliesszylinder gemäss Anspruch 1 gelöst. Beim erfindungsgemässen Schliesszylinder ist der Kupplungsteil im wesentlichen im Ansatz an der Rückseite der Verdickung geführt. Die Führungsschlitze für die Kupplung können damit in diesen Ansatz eingearbeitet werden. Damit ist vermieden, dass der Führungsschlitz die Verdickung des Zylinderkerns schwächt, wie dies bisher der Fall war. Der Zylinderkern kann somit wesentlich massiver ausgebildet sein und damit ist mit einer kürzeren Verdickung eine ebenso hohe Zugsicherheit wie bisher erreichbar. Wesentlich ist zudem, dass der Ansatz einen kleineren Durchmesser aufweist als der Aussendurchmesser der Verdikkung. Damit ist ermöglicht, dass der Mitnehmer, in welchen der Ansatz eingreift, mit einer wesentlich stabileren Wandung ausgebildet werden kann.The task is with a generic locking cylinder solved according to claim 1. In the inventive Locking cylinder is essentially the coupling part Approach led to the back of the thickening. The guide slots for the clutch can use this approach be incorporated. This prevents the Guide slot weakens the thickening of the cylinder core, as has been the case so far. The cylinder core can thus be designed to be much more massive and thus with a shorter thickening just as high train safety as previously available. It is also essential that the approach has a smaller diameter than the outer diameter of the thickening. This enables the driver in which the approach intervenes with a much more stable wall can be trained.

Nach einer Weiterbildung der Erfindung ist die Verdickung in das Zylindergehäuse und/oder in ein Verlängerungsstück des Zylindergehäuses eingelassen. Die Verdickung kann durch diese Massnahme nicht nur wesentlich massiver sondern zugleich auch länger ausgebildet werden, wodurch die Sicherheit gegen ein Abziehen des türaussenseitigen Zylinderkerns noch weiter erhöht wird. Der Bereich für eine individuelle Anpassung an unterschiedliche Sicherheitsanforderungen ist damit zusätzlich erweitert.According to a development of the invention, the thickening in the cylinder housing and / or in an extension piece of the cylinder housing. The thickening can be caused by this measure not only much more massive but at the same time can also be trained longer, increasing security against pulling off the outside of the cylinder core is increased still further. The area for an individual Adaptation to different security requirements thus further expanded.

Da beim erfindungsgemässen Schliesszylinder der türaussenseitige Zylinderkern äusserst ausreisssicher im Zylindergehäuse verankert ist, können mit einer Abziehvorrichtung entsprechend sehr hohe Kräfte zum Zerreissen des Schliesszylinders im Bereich der Stulpschraubenbohrung ausgeübt werden. Um ein solches Zerreissen zu verhindern, ist gemäss einer Weiterbildung der Erfindung ein Verbindungssteg vorgesehen, der im Bereich der Stulpschraubenbohrung verdickt ist, wobei diese Verdickung breiter ausgebildet ist als eine Ausnehmung für den Durchgang des Mitnehmers. Die Verdikkung des Steges kann in vorteilhafter Weise durch ein aufgesetztes Rohrstück realisiert werden. Weitere vorteilhafte Merkmale sind Gegenstand abhängiger Patentansprüche.Since in the locking cylinder according to the invention the outside of the door Cylinder core extremely tear-proof in the cylinder housing is anchored with a puller correspondingly very high forces for tearing the locking cylinder exercised in the area of the faceplate screw hole become. To prevent such tearing, according to a further development of the invention provides a connecting web, which thickens in the area of the faceplate screw hole is, this thickening is wider than one Recess for the passage of the driver. The thickening of the web can advantageously by an attached Pipe piece can be realized. More beneficial Features are the subject of dependent claims.

Der in den Figuren 1 bis 4 gezeigte Schliesszylinder 1 ist ein sogenannter Doppelschliesszylinder und weist zwei Gehäuseteile 2 und 3 auf, die mit einem separat hergestellten Verbindungssteg 20 fest miteinander verbunden sind. Die Gehäuseteile 2 und 3 besitzen jeweils eine durchgehende, zylindrische Gehäuseöffnung 11, in der jeweils ein Zylinderkern 4 gelagert ist. Wenigstens ein türaussenseitiger Zylinderkern 4 ist von der Rückseite des Gehäuseteils 2 in die Gehäuseöffnung 11 eingesetzt und besitzt eine flanschartige Verdickung 13, die wenigstens bereichsweise in eine korrespondierende Erweiterung 12 der Oeffnung 11 eingreift. Die Verdickung 13 ist insbesondere beim türaussenseitigen Zylinderkern 4 vorgesehen, da dieser einem gewaltsamen Einbruchversuch besonders ausgesetzt ist. Der andere Zylinderkern kann wie üblich ausgebildet und entsprechend von vorne in die entsprechende Gehäuseöffnung 11 eingesetzt sein.The locking cylinder 1 shown in FIGS. 1 to 4 is a so-called double lock cylinder and has two housing parts 2 and 3 with a separately manufactured Connecting web 20 are firmly connected. The housing parts 2 and 3 each have a continuous, cylindrical Housing opening 11, in each of which a cylinder core 4 is stored. At least a cylinder core on the outside of the door 4 is from the back of the housing part 2 in the housing opening 11 inserted and has a flange-like thickening 13, at least in some areas into a corresponding extension 12 of the opening 11 intervenes. The thickening 13 is in particular in the case of the outside of the door Cylinder core 4 provided since this one violent attempted break-in is particularly exposed. The other cylinder core can be designed as usual and accordingly from the front into the corresponding housing opening 11 be used.

An der Rückseite der Verdickung 13 ist ein Ansatz 14 angeformt, in dem ein Führungsschlitz 25 eingearbeitet ist. In diesem Schlitz 25 ist ein an sich bekanntes Kupplungsteil 24 längsverschieblich geführt. Dieses Kupplungsteil 24 dient in an sich bekannter Weise zum Kuppeln der Zylinderkerne mit einem Mitnehmer 15, an dem zur Betätigung eines Schlossriegels ein Nocken 16 angeformt ist. Dieser Mitnehmer 15 ist mit einer Ausnehmung 26 versehen, in welche der Ansatz 14 eingreift.A shoulder 14 is formed on the back of the thickening 13, in which a guide slot 25 is incorporated. In this slot 25 is a known coupling part 24 guided longitudinally. This coupling part 24 serves in a manner known per se for coupling the cylinder cores with a driver 15 on which to actuate a Lock bolt a cam 16 is formed. This driver 15 is provided with a recess 26 into which the Approach 14 intervenes.

Zur Betätigung des Schliesszylinders 1 wird ein hier nicht gezeigter Steckschlüssel in einen Schlüsselkanal 5 eingesetzt und das Kupplungsteil 24 aus der in der Figur 2 gezeigten Position nach rechts verschoben, wonach der Zylinderkern 4 mit dem Mitnehmer 15 gekuppelt ist. Durch den Steckschlüssel sind die hier nicht gezeigten Zuhaltungen eingeordnet, so dass der Zylinderkern 4 und damit der Mitnehmer 5 gedreht werden können.To actuate the lock cylinder 1 is not here The socket wrench shown is inserted into a key channel 5 and the coupling part 24 from that shown in FIG Position shifted to the right, after which the cylinder core 4 is coupled to the driver 15. By the Socket wrenches are the tumblers not shown here arranged so that the cylinder core 4 and thus the driver 5 can be rotated.

Zur Führung des Zylinderkerns 4 im Gehäuseteil 2 weist dieser an seiner Stirnseite zwei im Abstand zueinander angeordnete Sackbohrungen 7 sowie einen radialen Schlitz 8 auf. In den Schlitz 8 ist ein halbmondförmiger Riegelkörper 9 eingelegt, der durch gehärtete Stahlstifte 6, welche in die Bohrungen 7 eingesetzt sind, in einer Position gehalten ist, in welcher er in eine umlaufende Rille 10 in der Innenseite der Gehäuseöffnung 11 eingreift. Der Riegelkörper 9 ist in der Rille 10 gleitverschieblich geführt und wird beim Drehen des Zylinderkerns 4 in dieser Rille 10 in Umfangsrichtung verschoben. Der Riegelkörper 9 sichert zusammen mit der Verdickung 13 die genaue axiale Positionierung des Zylinderkerns 4 in der Oeffnung 11. Beim Montieren des Zylinderkerns 4 im Gehäuseteil 2 ist der Riegelkörper 9 im Schlitz 8 vollständig versenkt und steht somit an der Aussenseite des Zylinderkerns 4 nicht vor. Werden die Stahlstifte 6 in die Bohrungen 7 eingesetzt, so wird der Riegelkörper 9 nach aussen verschoben und greift schliesslich in die Rille 10 ein, wie dies in Figur 3 angedeutet ist. Die Stahlstifte 6 fixieren den Riegelkörper 9 und bilden gleichzeitig einen Aufbohrschutz. Der Riegelkörper 9 ist vorzugsweise ebenfalls aus einem harten Werkstoff hergestellt und bildet einen weiteren Schutz gegen ein Aufbohren des Zylinderkerns 4.To guide the cylinder core 4 in the housing part 2, this has on its end face two spaced apart Blind holes 7 and a radial slot 8. A crescent-shaped locking body 9 is in the slot 8 inserted by hardened steel pins 6, which in the Holes 7 are inserted, held in one position is in which it is in a circumferential groove 10 in the inside engages the housing opening 11. The bolt body 9 is slidably guided in the groove 10 and is when rotating the cylinder core 4 in this groove 10 in the circumferential direction postponed. The locking body 9 secures together with the thickening 13 the exact axial positioning of the cylinder core 4 in the opening 11. When mounting the Cylinder core 4 in the housing part 2 is the locking body 9 in Slot 8 completely sunk and is therefore at the Outside of the cylinder core 4 not in front. Will the Steel pins 6 inserted into the holes 7, so the Bolt body 9 moved outwards and finally engages in the groove 10, as indicated in Figure 3 is. The steel pins 6 fix the locking body 9 and form at the same time a drilling protection. The bolt body 9 is preferably also made of a hard material and forms a further protection against drilling of the cylinder core 4.

Die beiden Gehäuseteile 2 und 3 sind durch den in den Figuren 8, 9 und 10 näher gezeigten Verbindungssteg 20 fest miteinander verbunden. Zur Aufnahme des Steges 20 weisen die Gehäuseteile 2 und 3 jeweils eine Ausnehmung 21 auf, in die jeweils ein Arm 31 eingreift. In die Arme 31 ist jeweils eine Querbohrung 32 eingearbeitet, in die jeweils ein Stift 22 eingesetzt ist, der in eine Bohrung 35 des Gehäuseteils 2 bzw. 3 eingreift und den Steg 20 fest mit den Gehäuseteilen 2 und 3 verbindet. Der Steg 20 besitzt mittig eine Verdickung 33, die vorzugsweise durch ein aufgesetztes Rohrstück gebildet ist. An dieser Verdickung 33 ist von oben eine Ausnehmung 30 eingearbeitet, die bei einer Betätigung des Schliesszylinders 1 einen Durchgang des Mitnehmernockens 16 ermöglicht. Die Verdickung 33 ist wesentlich breiter als die Ausnehmung 30. Die Verdickung 33 ist somit vergleichsweise breit und greift an beiden Enden jeweils in einen Absatz 23 eines Zylindersacks 19 ein. Umlaufende Schultern 36 der Verdickung 33 liegen jeweils an einer Innenseite des Gehäuseteils 2 bzw. 3 an. Die Verdickung 33 ist vorzugsweise durch ein Rohrstück realisiert, das auf die Arme 31 aufgeschoben und mit Querstiften 37 fixiert ist. Dieses Rohrstück stabilisiert die Arme 31, insbesondere im Bereich der Stulpschraubenbohrung 29 und verhindert wirksam, dass der Steg bei einem Biegeversuch im Bereich der Stulpschraubenbohrung 29 infolge Materialermüdung bricht. Beim erfindungsgemässen Schliesszylinder 1 ist gewährleistet, dass der Zylinderkern 4 auch mit hohen Zugkräften nicht ausgerissen werden kann und zudem ein Bruch im Bereich der Stulpschraubenbohrung 29 kaum möglich ist. Die Figur 6 illustriert schematisch ein Ausreissversuch mittels einer Stahlschraube 27. Diese Stahlschraube 27 ist in den Zylinderkern 4 eingeschraubt und in Richtung des Pfeils 28 wird mittels einer hier nicht gezeigten Abziehvorrichtung eine sehr hohe Zugkraft auf den Zylinderkern 4 ausgeübt. Ein Ausziehen des Zylinderkerns 4 aus dem Gehäuseteil 2 ist insbesondere durch die Verdickung 13 verhindert, die mit einer Schulter 17 an der Rückseite des Gehäuseteils 2 anliegt. Die Figur 7 illustriert einen Bruch im Bereich der Stulpschraubenbohrung 29 als Folge eines solchen Ausreissversuchs. Bei einem solchen Versuch werden Biegekräfte auf den Steg 20 ausgeübt, mit dem Ziel einen Ermüdungsbruch zu erreichen. Beim erfindungsgemässen Schliesszylinder ist der Steg durch die umgreifende Verdikkung 33 stabilisiert und insbesondere werden die Verdickung 33 Biegekräfte aufgenommen.The two housing parts 2 and 3 are by the in the figures 8, 9 and 10 connecting web 20 shown in more detail connected with each other. Point for receiving the web 20 the housing parts 2 and 3 each have a recess 21 in each engages an arm 31. In the arms 31 is a transverse bore 32 incorporated into each Pin 22 is inserted into a bore 35 of the housing part 2 or 3 engages and the web 20 firmly with the housing parts 2 and 3 connects. The web 20 has a center a thickening 33, preferably by an attached Pipe piece is formed. At this thickening 33 is from a recess 30 incorporated at the top, when actuated of the locking cylinder 1 a passage of the driver cam 16 allows. The thickening 33 is essential wider than the recess 30. The thickening 33 is thus comparatively wide and engages in at both ends a shoulder 23 of a cylinder bag 19. Outstanding Shoulders 36 of the thickening 33 each lie on an inside of the housing part 2 or 3. The thickening 33 is preferably realized by a piece of pipe that on the arms 31 pushed on and fixed with cross pins 37 is. This piece of pipe stabilizes the arms 31, in particular in the area of the faceplate screw bore 29 and prevented effective that the web during a bending test in the area the faceplate screw bore 29 due to material fatigue breaks. The lock cylinder 1 according to the invention ensures that the cylinder core 4 even with high tensile forces cannot be torn out and also a break is hardly possible in the area of the faceplate screw bore 29. FIG. 6 schematically illustrates an attempted pull-out by means of a steel screw 27. This steel screw 27 is screwed into the cylinder core 4 and in the direction of Arrow 28 is by means of a pulling device, not shown here very high traction on the cylinder core 4 exercised. Pulling out the cylinder core 4 from the housing part 2 is prevented in particular by the thickening 13, the one with a shoulder 17 on the back of the housing part 2 is present. Figure 7 illustrates a break in Area of the faceplate screw bore 29 as a result of such Ausreissversuchs. In such an attempt Bending forces exerted on the web 20 with the aim of one To achieve fatigue fracture. In the inventive The locking cylinder is the bridge due to the extensive thickening 33 stabilized and in particular the thickening 33 bending forces added.

Die Figur 5 zeigt eine Variante des erfindungsgemässen Schliesszylinders 1. Bei dieser ist an der Rückseite des Gehäuseteils 2 ein Verlängerungsstück 34 angesetzt, welches einen zylindrischen Durchgang 38 besitzt, in welchen der Zylinderkern 4 mit seiner Verdickung 13 eingreift. Das Verlängerungsstück 34 verlängert den Gehäuseteil 2 in an sich bekannter Weise. Denkbar ist auch eine Ausführung mit mehreren Verlängerungsstücken 34, die aneinander gelegt sind. Schliesslich kann die Verdickung 13 gleichzeitig in eine korrespondierende Erweiterung des Gehäuseteils 2 eingreifen. Auch bei dieser Ausführung ist an der Rückseite der Verdickung 13 ein Ansatz 14 angeformt, in den ein Führungsschlitz 25 für das Kupplungsteil 24 eingearbeitet ist. Der Schlitz 25 bildet somit auch hier ein Führungsmittel für den Kupplungsteil 24.Figure 5 shows a variant of the inventive Lock cylinder 1. This is on the back of the Housing part 2 an extension piece 34 attached, which has a cylindrical passage 38 in which the Cylinder core 4 engages with its thickening 13. The extension piece 34 extends the housing part 2 in itself known way. A version with several is also conceivable Extension pieces 34, which are placed together. Finally, the thickening 13 can simultaneously in one intervene corresponding extension of the housing part 2. This version also has the Thickening 13 integrally formed an extension 14 into which a guide slot 25 is incorporated for the coupling part 24. The Slot 25 thus also forms a guide means for the coupling part 24.

Trotz den erheblichen Vorteilen des erfindungsgemässen Schliesszylinders ist dieser wie ersichtlich mit verhältnismässig wenigen, einfachen und robusten Bauteilen realisierbar, so dass erfindungsgemäss ein Schliesszylinder geschaffen wurde, welcher nicht nur den sicherheitstechnischen Anforderungen, einschliesslich einer einfachen Montage, in hervorragender Weise Rechnung trägt, sondern aufgrund seiner einfachen und robusten Ausführbarkeit kostenmässig günstig und betrieblich äusserst zuverlässig ist.Despite the considerable advantages of the invention As can be seen, the locking cylinder is proportionate few, simple and robust components can be realized, so that a locking cylinder is created according to the invention which was not only the safety-related Requirements, including simple assembly, takes into account in an excellent way, but because its simple and robust feasibility cost-effective is inexpensive and extremely reliable in operation.
