The anti-drilling device also has a shield that is in one Slot in the cylinder core in the area between the key channel and the division level or is arranged extending beyond the division level, wherein the hard material body and the shield are in one piece and the holes for the hard material body and the slot in the same cross-sectional plane of the cylinder core.

Keine der angezogenen Druckschriften zeigt ein Steckzylinderschloß, insbesondere zur Verwendung an Schutzvorrichtungen und Fallen für Spiel- und Warenautomaten, an Gitterrolltoren, an beweglichen Schutzgittern oder dergleichen, bei denen es darum geht, das Steckzylinderschloß selbst einbruchssicherer dadurch zu gestalten, daß das gesamte Schloß nicht mehr aus der dafür vorgesehenen Öffnung herausgezogen werden kann.In particular, none of the cited documents shows a cylinder lock for use on safety devices and traps for gaming and vending machines, on roller shutter gates, on movable safety guards or the like, where it comes to making the cylinder lock itself burglar-proof by designing that the entire castle is no longer out of it provided opening can be pulled out.

Der Erfindung liegt die Aufgabe zugrunde, ein Steckzylinderschloß zur Sicherung eines Objekts der vorausgesetzten Gattung wesentlich einbruchssicherer zu machen.The invention has for its object to provide a cylinder lock for security of an object of the presupposed type much more burglar-proof close.

Die Aufgabe wird durch die in Patentanspruch 1 wiedergegebenen Merkmale gelöst. The object is achieved by the features set out in claim 1 .

Beim Stand der Technik wird bei einem Einbruch der äußere Mantel des Zylindergehäuses deformiert und die Wandungen im Bereich der endstirnseitigen Bohrung nach innen gedrückt. Dabei wird auch der Schubriegel entweder abgeschert oder soweit umgebogen, daß er relativ problemlos aus der Öffnung des zu schützenden Objektes herausgerissen werden kann. Das ganze Schloß läßt sich danach aus der Öffnung herausziehen. Versuche der Anmelderin haben dabei gezeigt, daß die auftretenden Sprengkräfte sich annähernd gleichförmig auf die Wandung der Bohrung und damit auf den Zylindermantel übertragen, wobei so große Kräfte auftreten, daß auch unter den gegebenen Verhältnissen bei stärkster Wandausführung der Zylinder zerstört und der Schubriegel abgerissen und abgeschert wird. Berücksichtigt werden muß dabei, daß bei Schutzvorrichtungen und Fallen für Spiel- und Warenautomaten oder dergleichen die Einbauverhältnisse festliegen. Insbesondere ist der Abstand zwischen Schubriegel und einer inneren Wandung des zu schützenden Objektes festliegend und kann nicht beliebig vergrößert werden, so daß man im Bereich des inneren Endabschnittes des Steckzylinders hinsichtlich konstruktiver Maßnahmen sehr eingeschränkt ist. In the prior art, the outer casing of the cylinder housing is in the event of a break-in deformed and the walls in the area of the end face Hole pressed inwards. The slide bolt is also either sheared off or bent so far that it leaves the opening relatively easily of the object to be protected can be torn out. The whole castle can then be pulled out of the opening. Attempts by the applicant shown that the explosive forces occurring are approximately uniform transferred to the wall of the bore and thus to the cylinder jacket, forces so great that even under the given conditions with the strongest wall design the cylinder is destroyed and the The slide bolt is torn off and sheared off. It must be taken into account that with guards and traps for gaming and vending machines or the like, the installation conditions are fixed. In particular, the distance between the slide bolt and an inner wall of the to be protected Object fixed and can not be enlarged arbitrarily, so that one in Area of the inner end portion of the plug-in cylinder in terms of construction Measures is very limited.

Durch die Erfindung wird erreicht, daß die auftretenden hohen Deformationskräfte, die bei einem Einbruch auf den inneren Endabschnitt des Zylindergehäuses übertragbar sind, von der Stützscheibe gleichmäßig aufgenommen werden. Die Stützscheibe verhindert dabei eine Deformation des Zylindergehäuses.The invention ensures that the high deformation forces that occur, the case of a break-in on the inner end portion of the cylinder housing are transferable, evenly absorbed by the support disc become. The support disc prevents deformation of the Cylinder housing.

Betrachtet man das Steckzylinderschloß als einen Körper, so kann eine in Längsachsrichtung auf das Steckzylinderschloß aufgebrachte Zugkraft den Schubriegel deformieren. Dadurch, daß an dem endseitigen inneren Ende des Zylindergehäuses eine tangentiale Fläche vorhanden ist, wird erreicht, daß der Schubriegel sich auf diese Fläche umlegen und abstützen kann, so daß im weiteren Verlauf des Aufbruchversuches der Schubriegel wie ein Keil in der Aufnahmeöffnung für den Steckzylinder wirkt, das heißt das Steckzylinderschloß läßt sich nicht aus der Öffnung des Objektes herausziehen. Je größer die Zugkraft ist, die auf das Steckzylinderschloß aufgebracht wird, desto größer ist die Keilwirkung zwischen dem Steckzylinderschloß und dem Schubriegel sowie der Aufnahmeöffnung des zu schützenden Objektes. Stützscheibe, Schubriegel und tangentiale Anlagefläche für den Schubriegel verstärken also das Steckzylinderschloß gerade in dem gefährdeten Bereich dermaßen, daß nach der üblichen Ziehmethode mittels einer Schraube ein solches Steckzylinderschloß nicht mehr herausgerissen werden kann.If one considers the plug cylinder lock as a body, one can in Longitudinal axis direction applied to the cylinder lock the Deform the slide bolt. The fact that at the end inner end of the Cylinder housing has a tangential surface, it is achieved that the The slide latch can be folded down and supported on this surface, so that in further progress of the attempt to break open the slide bolt like a wedge in the Receiving opening for the plug-in cylinder acts, that is, the plug-in cylinder lock cannot be pulled out of the opening of the object. The bigger the greater the tensile force that is applied to the cylinder lock is the wedge effect between the cylinder lock and the slide bolt and the receiving opening of the object to be protected. Support disc, Push bars and tangential contact surface for the push bar reinforce the cylinder lock just in the hazardous area so that after the usual pulling method using a screw such a cylinder lock can no longer be torn out.

Bei Ausgestaltung gemäß Patentanspruch 2 stützt sich die Stützscheibe auf ihrem Umfang allseitig gleichmäßig an einer formmäßig angepaßten Innenwand des Zylindergehäuses ab.In the embodiment according to claim 2 , the support disk is supported on its circumference evenly on all sides on a shape-matched inner wall of the cylinder housing.

Gemäß Patentanspruch 3 ist die Stützscheibe unter Preßpassung in der Öffnung des Zylindergehäuses angeordnet.According to claim 3 , the support disk is arranged with a press fit in the opening of the cylinder housing.

Bei der Ausführungsform nach Patentanspruch 4 ist die Stützscheibe in ein Gewinde der Aufnahmeöffnung eingeschraubt.In the embodiment according to claim 4 , the support disc is screwed into a thread of the receiving opening.

Bei der Ausführungsform nach Patentanspruch 5 ist die Stützscheibe eingeklebt, während sie bei der Ausführungsform nach Patentanspruch 6 eingelötet und bei der Ausführungsform nach Patentanspruch 7 eingeschweißt ist.In the embodiment according to claim 5 , the support disc is glued in, while it is soldered in the embodiment according to claim 6 and welded in the embodiment according to claim 7 .

Es sind auch im Rahmen des Erfindungsgedankens Ausführungsformen denkbar, bei denen das Zylindergehäuse mit mehreren Stufen oder Absätzen vorgesehen ist, in die ein formmäßig angepaßter Stützkörper in Scheibenform eingreift, so daß dieser nicht nur radial, sondern auch achsial das Zylindergehäuse in diesem Bereich versteift und abstützt - Patentanspruch 8.There are also conceivable within the scope of the inventive concept embodiments in which the cylinder housing is provided with a plurality of steps or shoulders into which a form-adapted support body in disk form engages, so that this not only stiffens and supports the cylinder housing in this area radially but also axially - Claim 8 .

Gemäß Patentanspruch 9 ist die Stützscheibe in einer am inneren Ende des Zylindergehäuses angeordneten, im Durchmesser vergrößerten Erweiterung des Zylindergehäuses angeordnet.According to claim 9 , the support disc is arranged in an arranged at the inner end of the cylinder housing, enlarged in diameter of the cylinder housing.

Gemäß Patentanspruch 10 besteht die Stützscheibe aus Panzerstahl der Waffentechnik, zum Beispiel wie er für Gehäuse von Kampfpanzern benutzt wird. Die Stützscheibe kann auch aus einem hochharten, hochvergüteten Sonderstahl, insbesondere Panzerstahl, bestehen. Solche Stähle können zum Beispiel martinsitaushärtbare Stähle sein. Im lösungsgeglühten Zustand kann zum Beispiel ein martinsitaushärtender Stahl folgende Charakteristika aufweisen: Streckgrenze 800 bis 1000 N/mm2 Festigkeit 1100 bis 1300 N/mm2 Bruchdehnung etwa 15 % Brucheinschnürung 7 bis 15 % Härte 350 HB According to claim 10 , the support disc consists of armored steel weapon technology, for example as it is used for the casing of battle tanks. The support disc can also consist of a very hard, high-tempered special steel, in particular armored steel. Such steels can be, for example, martinsite-hardenable steels. In the solution-annealed condition, for example, a martinsite-hardening steel can have the following characteristics: Stretch limit 800 to 1000 N / mm 2 strength 1100 to 1300 N / mm 2 Elongation at break 15% Constriction 7 to 15% hardness 350 HB

Dagegen sind die entsprechenden Charakteristika desselben martinsitaushärtbaren Stahles im warmausgelagerten Zustand folgende: Streckgrenze 1600 bis 2700 N/mm2 Festigkeit 1700 bis 2800 N/mm2 Bruchdehnung 4 bis 18 % Brucheinschnürung 15 bis 50 % Härte 500 bis 800 HB In contrast, the corresponding characteristics of the same martinsite-hardenable steel in the hot-aged state are as follows: Stretch limit 1600 to 2700 N / mm 2 strength 1700 to 2800 N / mm 2 Elongation at break 4 to 18% Constriction 15 to 50% hardness 500 to 800 HB

Ein derartiger, martinsitaushärtbarer Stahl kann zum Beispiel 5,0 % Mo 18,0 % Ni 10,0 % Co 1,0 % Ti 4-6 % Mo 16-19 % Ni 7-11 % Co 0,3-1,5 % Ti oder zum Beispiel 8 bis 13 % Cr, vorzugsweise 8,7 bis 9,3 % Cr 7,8 bis 11 % Ni, vorzugsweise 8,3 bis 10,2 % Ni 4,5 bis 1 % Mo, vorzugsweise 2,9 bis 1,9 % Mo 1,9 bis 3,2 % Co, vorzugsweise 2,0 bis 3,1 % Co 0,5 bis 1,9 % Ti, vorzugsweise 0,8 % Ti aufweisen.Such a martinsite hardenable steel, for example 5.0% Mon 18.0% Ni 10.0% Co 1.0% Ti 4-6% Mon 16-19% Ni 7-11% Co 0.3-1.5% Ti or for example 8 to 13% Cr, preferably 8.7 to 9.3% Cr 7.8 to 11% Ni, preferably 8.3 to 10.2% Ni 4.5 to 1% Mo, preferably 2.9 to 1.9% Mo 1.9 to 3.2% Co, preferably 2.0 to 3.1% Co 0.5 to 1.9% Ti, preferably 0.8% Ti exhibit.

Während martinsitaushärtbare Stähle im lösungsgeglühten Zustand relativ zäh und gut zu verformen sind, sind sie im warmausgehärteten Zustand extrem hart. Derartige Härten können gegebenenfalls für die Stützscheiben verwendet werden. Der Verwendung von Blechen mit extrem hoher Härte sind sonst normalerweise durch die mangelnde Verschweißbarkeit Grenzen gesetzt, was vorliegend aber keine Rolle spielt.Relatively tough, hardenable steels in solution-annealed condition and are easy to deform, they are extreme when thermoset hard. Such hardnesses can optionally be used for the support disks become. The use of sheets with extremely high hardness are otherwise normal due to the lack of weldability, there are limits to what is available but doesn't matter.

Bei einer bevorzugten Ausführungsform der Erfindung besteht die Stützscheibe aus Bronze. Bronze hat ein hohes Druckaufnahmevermögen, zerplatzt unter Druck nicht so leicht und deformiert sich nicht so wie zum Beispiel gewisse Stahlsorten - Patentanspruch 11.In a preferred embodiment of the invention, the support disk is made of bronze. Bronze has a high pressure absorption capacity, does not burst as easily under pressure and does not deform as for example certain types of steel - claim 11 .

Gemäß Patentanspruch 12 wird als Werkstoff für die Stützscheibe CuSn8 verwendet. According to claim 12 , CuSn8 is used as the material for the support disk.

Dabei hat es sich als vorteilhaft erwiesen, wenn der Werkstoff mindestens eine Zugfestigkeit von 390 bis 750 N/mm2, vorzugsweise 690 N/mm2, eine 0,2 % Dehngrenze von 290 bis 700, vorzugsweise 640 N/mm2, eine Bruchdehnung von 60 bis 10, vorzugsweise 10, und eine Brinellhärte HB von 90 bis 250, vorzugsweise 220, aufweist.It has proven to be advantageous if the material has at least a tensile strength of 390 to 750 N / mm 2 , preferably 690 N / mm 2 , a 0.2% proof stress of 290 to 700, preferably 640 N / mm 2 , an elongation at break from 60 to 10, preferably 10, and a Brinell hardness HB from 90 to 250, preferably 220.

Patentanspruch 13 beschreibt eine vorteilhafte Ausführungsform. Claim 13 describes an advantageous embodiment.

Eine weitere sehr vorteilhafte Ausführungsform ist in Patentanspruch 14 beschrieben. Bei dieser ist praktisch das gesamte Schloß in einer Hülse aus Stahl eingekapselt. Diese Stahlmantelhülse umschließt das Zylindergehäuse und ist an ihrem nach außen gekehrten, aus dem Objekt herausragenden Endabschnitt durch eine ebenfalls aus Stahl bestehende Schutzhaube auch endstirnseitig geschützt.Another very advantageous embodiment is described in claim 14 . Practically the entire lock is encapsulated in a steel sleeve. This steel jacket sleeve encloses the cylinder housing and is also protected on its end face at its outward-facing end section protruding from the object by a protective hood also made of steel.

Die Patentansprüche 15 bis 21 beschreiben weitere erfinderische Ausführungsformen. Claims 15 to 21 describe further inventive embodiments.

Gemäß Patentanspruch 21 weist die endstirnseitig angeordnete, nach außen gekehrte Schutzhaube eine besondere Formgebung auf, durch die der Zylinderkern nach außen weiterhin gegen Herausziehen gesichert wird.According to claim 21 , the protective cover arranged at the end face and facing outwards has a special shape by which the cylinder core is further secured against being pulled out.

In den Patentansprüchen 22 bis 36 sind weitere erfinderische Ausgestaltungen beschrieben.Further inventive configurations are described in patent claims 22 to 36 .

Bei Ausgestaltung gemäß Patentanspruch 22 stützt die Schutzhaube den nach außen gekehrten stirnseitigen Endbereich des Zylinderkerns radial ab.In the embodiment according to claim 22 , the protective hood radially supports the outward-facing end region of the cylinder core.

Eine besonders vorteilhafte Ausführungsform ist in Patentanspruch 23 beschrieben. Bei dieser ist ein Zylinderkernkopf mit dem eigentlichen Zylinderkern durch eine Sollbruchstelle verbunden, die bei einem Einbruchsversuch bei einer vorbestimmten Belastung abtrennbar ist. Auf diese Weise wird verhindert, daß nur vorbestimmte Kräfte bei einem Einbruchsversuch auf die Lagerung für das Steckzylinderschloß übertragbar sind.A particularly advantageous embodiment is described in claim 23 . In this case, a cylinder core head is connected to the actual cylinder core by a predetermined breaking point, which can be detached during a break-in attempt at a predetermined load. In this way it is prevented that only predetermined forces can be transmitted to the storage for the plug-in cylinder lock in the event of a break-in attempt.

Patentansprüche 24 bis 27 beschreiben vorteilhafte Ausführungsformen der Erfindung. Claims 24 to 27 describe advantageous embodiments of the invention.

Eine weitere, besonders vorteilhafte Ausführungsform der Erfindung ist in Patentanspruch 28 beschrieben. Durch Vollhartmetallstifte wird verhindert, daß zum Beispiel eine Ziehschraube in den Zylinderkern einschraubbar ist. Diese trifft nämlich nach kurzem Weg bereits auf einen Vollhartmetallstift und wird durch diesen abgelenkt, so daß die Schneiden der Ziehschraube stumpf werden und nicht weiter in das Material des Zylinderkerns eindringen können.A further, particularly advantageous embodiment of the invention is described in claim 28 . Solid carbide pins prevent a pulling screw from being screwed into the cylinder core, for example. After a short distance, this hits a solid carbide pin and is deflected by it, so that the cutting edges of the drawing screw become blunt and cannot penetrate further into the material of the cylinder core.

Weitere, sehr vorteilhafte Ausführungsformen der Erfindung sind in den Patentansprüchen 29 bis 31 beschrieben.Further, very advantageous embodiments of the invention are described in claims 29 to 31 .

Durch die Anordnung der Vollhartmetallstifte trifft ein Einbruchwerkzeug, insbesondere eine Ziehschraube, mit Sicherheit auf einen Vollhartmetallstift.The arrangement of the solid carbide pins hits a burglary tool, especially a pull screw, certainly on one Solid carbide pin.

Patentanspruch 32 beschreibt eine besondere, erfinderische Lösung für die Anordnung von Vollhartmetallstiften, was auch für Patentanspruch 33 gilt. Claim 32 describes a special, inventive solution for the arrangement of solid carbide pins, which also applies to claim 33.

Patentanspruch 34 beschreibt eine weitere Ausführungsform, bei welcher der Zylinderkernkopf mit dem eigentlichen Zylinderkern durch eine Klebverbindung gekuppelt ist, die bei Überschreitung einer vorbestimmten Beanspruchung abtrennbar ist. Claim 34 describes a further embodiment in which the cylinder core head is coupled to the actual cylinder core by an adhesive connection which can be separated when a predetermined load is exceeded.

Bei der Ausführungsform nach Patentanspruch 35 ist der Zylinderkernkopf mit dem Zylinderkern über mehrere Stifte oder Schrauben gekuppelt, die ebenfalls beim Überschreiten einer definierten Scher- und/oder Zugbeanspruchung abreißen.In the embodiment according to claim 35 , the cylinder core head is coupled to the cylinder core via a plurality of pins or screws, which also tear off when a defined shear and / or tensile stress is exceeded.

Die Sollbruchstelle wird bei der erfinderischen Lösung gemäß Patentanspruch 36 durch eine Schwächung des Zylinderkerns an einer bestimmten Stelle gebildet. Diese Schwächung wird durch mehrere radial gerichtete Ausnehmungen, zum Beispiel Bohrungen gebildet. An dieser Stelle wird auf diese Weise eine Sollbruchstelle hergestellt, an der der Zylinderkernkopf von dem Zylinderkern definiert abtrennbar ist.The predetermined breaking point is formed in the inventive solution according to claim 36 by weakening the cylinder core at a certain point. This weakening is formed by several radially directed recesses, for example bores. At this point, a predetermined breaking point is produced in this way, at which the cylinder core head can be separated from the cylinder core in a defined manner.

The housing pins 9 to 13 are each against the restoring force of compression springs stored in the drawing only are indicated schematically and are each against the associated Core pin 4 to 8 facing away from the relevant housing pin 9 to 13 support under tension so that the core pins 4 to 8 accordingly are spring loaded. The core pins 4 to 8 and the housing pins 9 to 13 form the tumblers of the cylinder lock.

Das Zylindergehäuse 1 weist einen hinteren (inneren) Endabschnitt 14 auf, der eine nach hinten ausmündende Öffnung 15 besitzt, in der eine Stützscheibe 16 angeordnet ist. Die Stützscheibe 16 ist vorliegend unter Preßpassung in der Öffnung 15 angeordnet und als Stufenscheibe ausgebildet. Die Öffnung 15 ist kreisförmig ausgestaltet. Die Stützscheibe 16 besteht bei der dargestellten Ausführungsform aus einer Zinn-Bronze-Legierung CuSn8 mit zum Beispiel folgender Analyse:The cylinder housing 1 has a rear (inner) end portion 14 which has a rear-opening opening 15 in which a support disk 16 is arranged. The support disc 16 is present in the press fit in the Opening 15 arranged and designed as a step plate. The opening 15 is designed circular. The support disk 16 is in the embodiment shown made of a tin-bronze alloy CuSn8 with, for example, the following Analysis:

Wie man erkennt, ist die in achsialer Richtung gemessene Dicke F geringer als die achsiale Länge E der Öffnung 15 des Zylindergehäuseabschnittes 14. Auf diese Weise ist ein Achsialspalt 17 zu dem Kopf 18 einer Schraube 19, die in eine Gewindesackbohrung 20 des Zylinderkerns 2 eingeschraubt ist. Die Schraube 19 verbindet getrieblich einen Schubriegel 21 mit dem Zylinderkern 2. Dieser Schubriegel 21 tritt aus einer schlitzförmigen, sich im Umfang über einen Kreissektor erstreckenden Aussparung 22 des Zylindergehäuses 1 heraus. Die Bewegung des Zylinderkerns 2 wird durch einen Anschlagstift 23 begrenzt, der einerseits in einen Radialschlitz 24 eingreift, der sich etwa um 90 Grad oder einen anderen Winkel in Umfangsrichtung des Zylinderkerns 2 erstreckt und der andererseits in einer Durchgangsbohrung 25 des Zylindergehäuses 1 angeordnet ist. Der Kopf des Anschlagstiftes 23 greift in eine Bohrung 26 ein, die in einer Stahlmantelhülse 27 angeordnet ist, die das Zylindergehäuse 1 auf dem größten Teil seiner Länge umschließt. Auf dem nach außen gekehrten Längenabschnitt der Stahlmantelhülse 27 ist von außen eine nach Art einer Muffe oder Hutmutter ausgebildete Schutzhaube 28 aus Stahl aufgesetzt, die mit einem achsialen Längenabschnitt 29 die Stahlmantelhülse 27 auf einem Teil ihres nach außen gekehrten Längenabschnittes und mit einem materialmäßig einstückig damit verbundenen radialen Abschnittes auch die Stirnseite der Stahlmantelhülse 27 und einen Teil der Stirnseite des Zylindergehäuses 1 abdeckt.As can be seen, the thickness F measured in the axial direction is less than the axial length E of the opening 15 of the cylinder housing section 14 in this way there is an axial gap 17 to the head 18 of a screw 19 which in a threaded blind bore 20 of the cylinder core 2 is screwed in. The Screw 19 connects a slide bolt 21 with the cylinder core 2. This slide bolt 21 emerges from a slit-shaped, the circumference of a Circular sector extending recess 22 of the cylinder housing 1 out. The Movement of the cylinder core 2 is limited by a stop pin 23 which on the one hand engages in a radial slot 24 which is about 90 degrees or extends another angle in the circumferential direction of the cylinder core 2 and which, on the other hand, is arranged in a through bore 25 of the cylinder housing 1 is. The head of the stop pin 23 engages in a bore 26 which is arranged in a steel jacket sleeve 27 on the cylinder housing 1 encompasses most of its length. On the outside Length section of the steel jacket sleeve 27 is from the outside one of the kind Sleeve or cap nut trained protective hood 28 made of steel, the with an axial length section 29, the steel jacket sleeve 27 on a Part of its length section facing outwards and with a material integrally connected radial section also the end face the steel jacket sleeve 27 and part of the end face of the cylinder housing 1 covers.

Die Schutzhaube 28 ist mit der Stahlmantelhülse 27 und mit dem Zylindergehäuse 1 durch mehrere über den Umfang verteilt angeordnete Radialstifte 30 verbunden, die an der äußeren Peripherie des Längenabschnittes 29 enden.The protective hood 28 is with the steel jacket sleeve 27 and with the cylinder housing 1 by a plurality of radial pins 30 distributed over the circumference connected, which end on the outer periphery of the length section 29.

Bei 31 ist ein Arretierstift angeordnet, der in einen Schlitz 32 einer Wand 33 eingreift. Der Schlitz 32 erstreckt sich in Achslängsrichtung des Steckzylinderschlosses. Über diesen Arretierstift 31 können die Reaktionskräfte, die über den Flachschlüssel auf das Steckzylinderschloß übertragen werden, aufgenommen werden, so daß sich das Steckzylinderschloß nicht verdrehen kann.At 31, a locking pin is arranged, which in a slot 32 of a wall 33 intervenes. The slot 32 extends in the axial longitudinal direction of the cylinder lock. About this locking pin 31, the reaction forces that over the flat key are transferred to the cylinder lock be so that the cylinder lock cannot twist.

Bei 34 ist ein weiterer Radialstift angeordnet, der durch eine Durchgangsbohrung 35 der Stahlmantelhülse 27 hindurchgreift und in eine koaxial dazu angeordnete Sackbohrung 36 eingreift, die in dem Zylindergehäuse 1 angeordnet ist. Dadurch werden das Zylindergehäuse 1 und die Stahlmantelhülse 27 gegeneinander arretiert. At 34, another radial pin is arranged through a through hole 35 of the steel jacket sleeve 27 extends through and into a coaxially arranged Blind bore 36 engages, which is arranged in the cylinder housing 1 is. Characterized the cylinder housing 1 and the steel jacket sleeve 27 against each other locked.

Bei 37 und 38 sowie 39 sind Wände eines zu schützenden Objektes, zum Beispiel eines Spielautomaten, angedeutet. Die Wände 33, 37 und 38 weisen je eine Durchgangsbohrung auf, die koaxial zueinander angeordnet sind und in die das Steckzylinderschloß eingesteckt ist.At 37 and 38 and 39 are walls of an object to be protected, for example of a slot machine, indicated. The walls 33, 37 and 38 each have a through hole, which are arranged coaxially to each other and in which the cylinder lock is inserted.

Das Maß X liegt bei Spielautomaten in der Regel fest, so daß der Abstand zwischen der Stirnseite 40 und der Innenseite 41 der Wand 39 in der Regel gering ist. Dadurch, daß das Maß X konstruktiv vorgegeben ist, besteht normalerweise wenig Möglichkeit zur konstruktiven Gestaltung.The dimension X is usually fixed in slot machines, so that the distance between the end face 40 and the inside 41 of the wall 39 are generally small is. Due to the fact that the dimension X is given by design, it normally exists little opportunity for constructive design.

Wie aus Fig. 12 ersichtlich ist, ist der Zylindergehäuseabschnitt 14 an seiner der Verriegelungsstellung des Schubriegels 21 diametral gegenüberliegenden Seite mit einer tangential angeordneten, in Lächsachsrichtung des Zylindergehäuses 1 verlaufenden Fläche 42 versehen, gegen die sich der Schubriegel 21 bei einem Einbruchsversuch abstützen, auflegen und gegebenenfalls verkeilen kann.As can be seen from FIG. 12, the cylinder housing section 14 is on it the locking position of the slide bolt 21 diametrically opposite Side with a tangentially arranged, in the axial direction of the cylinder housing 1 extending surface 42 against which the slide bolt 21 Support, hang up and wedge if necessary in the event of a break-in can.

Aus den Fig. 10 und 11 ist die Ausbildung des Schubriegels 21 deutlicher zu entnehmen. Hieraus entnimmt man, daß der Schubriegel 21 einen seitwärts ausmündenden Schlitz 43 aufweist in den der Schraubenkopf 18 als Exzentereingreift. Der Schubriegel 21 ist durch eine Radialnut geführt. Der Schubriegel 21 ist an seiner Oberseite und Unterseite jeweils nach einem Kreisbogen 44 bzw. 45 verlaufend abgerundet ausgebildet.10 and 11, the design of the sliding bolt 21 is more clearly remove. From this it can be seen that the slide bolt 21 moves sideways opening slot 43 in which the screw head 18 engages as an eccentric. The slide bolt 21 is guided through a radial groove. Of the Slide latch 21 is on its top and bottom according to one Circular arcs 44 and 45 are rounded.

Der Schubriegel 21 besteht bei der dargestellten Ausführungsform aus nicht rostendem Stahl, zum Beispiel aus X 5 CrNi 18 10, Werkstoffnummer 1.4301. Ein solcher Stahl ist ein austenitischer Stahl, der bei Raumtemperatur im abgeschreckten Zustand folgende Eigenschaften aufweist:The slide bolt 21 does not consist of the embodiment shown rusting steel, for example made of X 5 CrNi 18 10, material number 1.4301. Such a steel is an austenitic steel that is quenched at room temperature Condition has the following properties:

Dichte 7,9 kg/dm3, der Elastizitätsmodul bei 20 Grad Celsius 200 kN/mm2, bei 100 Grad Celsius 194.Density 7.9 kg / dm 3 , the elastic modulus at 20 degrees Celsius 200 kN / mm 2 , at 100 degrees Celsius 194.

Die Stahlmantelhülse 27 besteht ebenfalls aus rostfreiem Stahl X 10 CrNiS 18 9, Werkstoffnummer 1.4305. Hier handelt es sich ebenfalls um einen austenitischen Stahl, der in abgeschrecktem Zustand folgende Werkstoffeigenschaften aufweist:The steel jacket sleeve 27 is also made of stainless steel X 10 CrNiS 18 9, material number 1.4305. This is also an austenitic one Steel, which has the following material properties when quenched having:

Zugfestigkeit 500 bis 700 N/mm2, Bruchdehnung ca. 35 %, Kerbschlagzähigkeit 160 mm nach DIN 17010. Tensile strength 500 to 700 N / mm 2 , elongation at break approx. 35%, impact strength 160 mm according to DIN 17010.

Deutlich erkennt man zum Beispiel aus den Fig. 1, 2, 3, 4, 6 und 8, daß die Schutzhaube 28 materialmäßig mit ihr einstückig verbundene, radial gerichtete Sektoren 46 bzw. 47 oder Radialsektoren aufweist, die die nach außen gekehrte Stirnseite 48 des Zylinderkerns 2 auf einem Teil ihrer Fläche übergreifen. Auf diese Weise wird der Zylinderkern 2 weiterhin gegen achsiales Herausziehen gesichert. Diese Radialsektoren 46 und 47 reichen bis unmittelbar an den Schlüsselkanal 3 heran, so daß auch Manipulationen mit Einbruchswerkzeugen erschwert werden.1, 2, 3, 4, 6 and 8 that the Protective hood 28 material-wise connected with it, directed radially Sectors 46 or 47 or radial sectors, which faces outwards Overlap the end face 48 of the cylinder core 2 on part of its surface. In this way, the cylinder core 2 is still against axial pulling out secured. These radial sectors 46 and 47 extend to immediately the key channel 3 so that tampering with intrusion tools become more difficult.

Wird eine Zugkraft P (Fig. 2, 3) auf das Steckzylinderschloß ausgeübt, dann kann dies dazu führen, daß der Schubriegel 21 so wie aus Fig. 2, 3 und 7 ersichtlich nach hinten in Richtung auf die Wand 39 definiert abgebogen wird, weil die tangential verlaufende Fläche 42 eine definierte Verformung des Schubriegels 21 ermöglicht. Wird nun versucht, das Steckzylinderschloß aus den Öffnungen des zu sichernden Objekts herauszuziehen, so führt dies zu einem Verkeilen des nach hinten gebogenen Schubriegels 21 in der betreffenden Ausnehmung der Wand 38, so daß ein Herausziehen unmöglich wird. Je größer nämlich die Zugkraft P auf das Steckzylinderschloß wird, desto größer ist die Verkeilungskraft. Ein Abscheren des Schubriegels 21 ist dadurch nicht möglich. Auch das radiale Deformieren des im Durchmesser vergrößerten Zylindergehäuseabschnitts 14 ist ausgeschlossen, weil dies die Stützscheibe 16 verhindert. Die dabei auftretenden Kräfte verteilen sich radial über den Umfang etwa gleichmäßig in der Öffnung 15.If a tensile force P (Fig. 2, 3) is exerted on the cylinder lock, then this can lead to the slide bolt 21 as shown in FIGS. 2, 3 and 7 is bent backwards towards wall 39 in a defined manner, because the tangential surface 42 a defined deformation of the Slide bolt 21 allows. Now tries to remove the cylinder lock pulling out the openings of the object to be secured, this leads to a wedging of the sliding bolt 21 bent backwards in the concerned Recess of the wall 38 so that it is impossible to pull it out. Each namely the greater the tensile force P on the plug-in cylinder lock, the greater is the wedging force. This does not result in the shear bolt 21 shearing off possible. Also the radial deformation of the enlarged diameter cylinder housing section 14 is excluded because this is the support disk 16 prevented. The forces that occur are distributed radially over the circumference approximately evenly in the opening 15.

Für die aus den Fig. 13 bis 25 ersichtliche Ausführungsform wurden für Teile gleicher Funktion die gleichen Bezugszeichen wie bei der Ausführungsform nach den Fig. 1 bis 12 verwendet. Die Funktionsweise der Ausführungsform nach den Fig. 13 bis 25 entspricht somit grundsätzlich der Ausführungsform nach den Fig. 1 bis 12, so daß hinsichtlich des grundsätzlichen Aufbaus und der Funktionsweise des Steckzylinderschlosses auf die im Zusammenhang mit der Ausführungsform nach den Fig. 1 bis 12 gemachten Ausführungen verwiesen werden kann.For the embodiment shown in FIGS. 13 to 25, parts have been same function, the same reference numerals as in the embodiment 1 to 12 used. The operation of the embodiment 13 to 25 thus basically corresponds to the embodiment 1 to 12, so that with regard to the basic structure and the functioning of the cylinder lock on the related the embodiment according to FIGS. 1 to 12 made references can be.

Die Ausführungsform nach den Fig. 13 bis 25 unterscheidet sich von der vorbeschriebenen Ausführungsform wie folgt:The embodiment according to FIGS. 13 to 25 differs from the one described above Embodiment as follows:

Zunächst ist die Schutzhaube 28 nicht mehr - wie bei der Ausführungsform nach den Fig. 1 bis 12 - mit Radialsektoren 46 versehen. Vielmehr ist der Zylinderkern 2 an seinem nach außen gekehrten Endabschnitt mit einem bei der dargestellten Ausführungsform im Durchmesser vergrößerten Zylinderkernkopf 49 versehen, der über eine Sollbruchstelle 50 materialmäßig einstückig mit dem Zylinderkern 2 verbunden ist. Der Zylinderkernkopf 49 kann aber im Bedarfsfalle auch den gleichen Durchmesser wie der Zylinderkern 2 aufweisen. First, the protective hood 28 is no longer - as in the embodiment 1 to 12 - provided with radial sectors 46. Rather, the cylinder core 2 at its outwardly facing end section with one at the Embodiment shown enlarged cylinder core head 49 provided, the material over a predetermined breaking point 50 in one piece with the Cylinder core 2 is connected. The cylinder core head 49 can, however, if necessary also have the same diameter as the cylinder core 2.

Die Sollbruchstelle 50 wird durch auf beide Seiten des Schlüsselkanals 3 vorhandene streifenförmige Materialteile gebildet, die bei dem dargestellten Ausführungsbeispiel nach außen durch parallel zueinander verlaufende, symmetrisch zur Drehachse des Zylinderkerns 2 angeordnete Wände 51 und 52 begrenzt wird. Diese Wände 51, 52 werden vorliegend durch je eine Radialnut 53 bzw. 54 gebildet. Die achsiale Breite G kann bei jeder Radialnut 53 bzw. 54 bei einem Ausführungsbeispiel 0,5 mm betragen. Beide Nuten 53 und 54 sind gleich groß und symmetrisch zur Längsachse angeordnet. Die Achsiallänge H des Zylinderkernkopfes 49 beträgt bei diesem Ausführungsbeispiel 6 mm, während die Nuten 53 und 54 etwa im achsialen Abstand von etwa der Nutbreite G hinter dem Zylinderkernkopf 49 angeordnet sind.The predetermined breaking point 50 is by existing on both sides of the key channel 3 strip-shaped material parts formed in the illustrated embodiment towards the outside by symmetrical parallel to each other walls 51 and 52 arranged to the axis of rotation of the cylinder core 2 are limited becomes. In the present case, these walls 51, 52 are each formed by a radial groove 53 or 54 formed. The axial width G can be in the case of any radial groove 53 or 54 an embodiment 0.5 mm. Both grooves 53 and 54 are arranged the same size and symmetrical to the longitudinal axis. The axial length H of the cylinder core head 49 in this embodiment is 6 mm, while the grooves 53 and 54 approximately at an axial distance of approximately the groove width G. are arranged behind the cylinder core head 49.

Selbstverständlich kann die Ausbildung der Sollbruchstelle 50 auch anders ausgeführt werden. Zum Beispiel ist es möglich, mehr als zwei Nuten vorzusehen. Schließlich ist es möglich, statt Nuten 53 und 54, die Sollbruchstelle 50 auch anders herzustellen, zum Beispiel durch mehrere Bohrungen, die parallel oder im Winkel zueinander verlaufen oder durch sonstige Querschnittsverringerungen im Bereich der Sollbruchstelle oder durch die Verwendung unterschiedlicher Materialien für den Zylinderkern 2 und den Zylinderkernkopf 49.Of course, the design of the predetermined breaking point 50 can also be different be carried out. For example, it is possible to provide more than two grooves. Finally, it is possible, instead of grooves 53 and 54, the predetermined breaking point 50 can also be produced differently, for example through several holes that are parallel or run at an angle to each other or by other cross-sectional reductions in the area of the predetermined breaking point or by using different ones Materials for the cylinder core 2 and the cylinder core head 49.

Deutlich erkennt man zum Beispiel aus Fig. 23, daß nach einem Abscheren des Zylinderkernkopfes 49 Materialstreifen an der Sollbruchstelle 50 übrig bleiben, die im Querschnitt wesentlich kleiner bemessen sind als der Kreisquerschnitt des Zylinderkerns 2. Dies bedeutet, daß nach dem Überschreiten einer vorbestimmten Zugkraft der Zylinderkernkopf 49 abgeschert wird. Die zum Beispiel durch eine Ziehschraube 55 auf den Zylinderkern 2 aufzuübenden Kräfte können dann so bemessen werden, daß zwar noch der Schubriegel 21 definiert umgebogen werden kann, um sich gegen die Fläche 42 (Fig. 12) anlegen zu können, um die gewünschte Verkeilungswirkung aufzubringen. Bevor jedoch weitere, zerstörerisch große Kräfte auf den Zylinderkern 2 übertragen werden können, wird der Zylinderkernkopf 49 an der Sollbruchstelle 50 abgeschert oder abgerissen, so daß der Aufbruchversuch auch hieran scheitert.It can be clearly seen, for example, from FIG. 23 that after the Cylinder core head 49 material strips remain at the predetermined breaking point 50, which are dimensioned much smaller in cross section than the circular cross section of the cylinder core 2. This means that after exceeding a predetermined Tractive force of the cylinder core head 49 is sheared off. For example forces to be exerted on the cylinder core 2 by a pull screw 55 then be dimensioned such that the slide bolt 21 is still defined can be bent to lay against the surface 42 (Fig. 12) to apply the desired wedging effect. Before however further, destructively large forces are transmitted to the cylinder core 2 can, the cylinder core head 49 is sheared off at the predetermined breaking point 50 or demolished, so that the attempt to break open fails.

Außerdem erkennt man besonders deutlich aus den Fig. 22 bis 25, daß der Zylinderkernkopf 49 neben der Längsmittenachse (Drehachse) des Zylinderkerns 2 mit einem Vollhartmetallstift 56 versehen ist, der somit orthogonal zur Drehachse des Zylinderkerns 2 verläuft und der an der äußeren Zylindermantelfläche des Zylinderkernkopfes 49 endet.In addition, it can be seen particularly clearly from FIGS. 22 to 25 that the Cylinder core head 49 next to the longitudinal center axis (axis of rotation) of the cylinder core 2 is provided with a solid carbide pin 56, which is thus orthogonal to The axis of rotation of the cylinder core 2 runs and that on the outer surface of the cylinder of the cylinder core head 49 ends.

Jenseits der Nuten 53 und 54, also im Steckschloß innen, ist der Zylinderkern 2 bei der dargestellten Ausführungsform auf jeder Seite seiner Drehachse mit je einem weiteren Vollhartmetallstift 57 bzw. 58 versehen. Diese Vollhartmetallstifte 57, 58 können prinzipiell die gleichen Dimensionierungen, zumindest im Durchmesser, erhalten wie der Vollhartmetallstift 56. Auch die Vollhartmetallstifte 57 und 58 enden jeweils an der äußeren Zylindermantelfläche des Zylinderkerns 2, so daß dieser in seiner Drehung nicht behindert wird. Als Hartmetall kommen nicht nur gehärtete Stähle, sondern auch Wolframkarbide und andere, bekannte Hartmetalle in Betracht.Beyond the grooves 53 and 54, i.e. inside the plug lock, is the cylinder core 2 in the embodiment shown on each side of its axis of rotation with each another solid carbide pin 57 or 58 provided. These solid carbide pins 57, 58 can in principle have the same dimensions, at least in Diameter preserved like solid carbide pin 56. Solid carbide pins as well 57 and 58 each end on the outer cylinder surface of the cylinder core 2, so that it is not hindered in its rotation. As a hard metal come not only hardened steels but also tungsten carbides and others, known carbides into consideration.

Wird nun eine Ziehschraube 55 in den Schlüsselkanal 3 eingeschraubt, so wird sie zunächst durch den Vollhartmetallstift 56 aus ihrer Längsachse abgelenkt (Fig. 25) und stößt dann entweder auf den Vollhartmetallstift 57 oder 58, kann also nur über einen geringen Teil ihrer Länge in den Schlüsselkanal 3 - wenn überhaupt - eingeschraubt werden, so daß sich nicht die beabsichtigten vollen Ziehbeanspruchungen auf den Zylinderkern 2 übertragen lassen. Der Einschraubversuch endet somit in der Regel an dem Vollhartmetallstift 57, so daß nur der Zylinderkernkopf 49 an der Sollbruchstelle 50 abgerissen werden kann. Da man es - wie oben beschrieben - durch die Ausbildung und Anordnung der Sollbruchstelle 50 in der Hand hat, die Abscher- oder Abreißkräfte vorher zu bestimmen, werden auf jeden Fall nur solche Kräfte auf das Steckzylinderschloß und dessen Gehäuse übertragen, die keine schädlichen Beanspruchungen für die Lagerung des Steckzylinderschlosses und dessen Aufnahme bedeuten.If a pulling screw 55 is now screwed into the key channel 3, then first deflected by its solid carbide pin 56 from its longitudinal axis (Fig. 25) and then either meets the solid carbide pin 57 or 58, can So only a small part of its length in the key channel 3 - if at all - be screwed in, so that the intended full Allow drawing stresses to be transferred to the cylinder core 2. The screw-in attempt thus usually ends at the solid carbide pin 57, so that only the cylinder core head 49 can be torn off at the predetermined breaking point 50. Since it - as described above - through the training and arrangement of the Has predetermined breaking point 50 in hand, the shear or tear forces before determine, in any case only such forces on the cylinder lock and transmit its housing that does not cause harmful stress mean for the storage of the plug-in cylinder lock and its inclusion.

Die Schneidspitzen der Ziehschraube 55 werden beim Einschrauben durch den Vollhartmetallstift 56 stumpf, so daß sie sich nicht mehr in den in der Regel aus Messing bestehenden Zylinderkernkopf 49 und den ebenfalls aus Messing bestehenden Zylinderkern 2 einschrauben lassen. Würde eine neue Ziehschraube 55 verwendet, die noch keine stumpfen Schneidspitzen aufweist, so trifft diese auf jeden Fall auf den Vollhartmetallstift 57 und kann dann ebenfalls nicht mehr weiter eingeschraubt werden.The cutting tips of the pull screw 55 are screwed in by the Solid carbide pin 56 blunt, so that they are no longer in the rule Brass existing cylinder core head 49 and also made of brass Have the cylinder core 2 screwed in. Would a new screw 55 used, which does not yet have blunt cutting tips, this hits in any case on the solid carbide pin 57 and then can also no longer be screwed in further.
