Description

Die Erfindung bezieht sich auf einen Profilschließzylinder mit einem Zylindergehäuse, das aus einem eine erste Axialbohrung und einen darin axial unverschieblich lagernden Zylinderkern sowie teilweise auch federbelastete Zuhaltungselemente enthaltenden ersten Gehäuseteil und einem damit über einen einen Einschnitt für den durch den Zylinderkern verdrehbaren Schließbart neben sich freilassenden Verbindungssteg einstückig verbundenen zweiten Gehäuseteil mit einer zur ersten axialbohrung koaxial verlaufenden zweiten Axialbohrung besteht, wobei der Zylinderkern einen in Längsrichtung verlaufenden Schlüsselkanal zur Aufnahme eines mit Einschnitten versehenen Schlüssels sowie weitere Zuhaltungselemente enthält, die zusammen mit den im ersten Gehäuseteil untergebrachten Zuhaltungselementen in eine die Drehbeweglichkeit des Zylinderkerns ermöglichende Freigabestellung zu bewegen sind.The invention relates to a profile lock cylinder with a cylinder housing, the first housing part containing a first axial bore and a cylinder core axially immovably mounted therein as well as spring-loaded tumbler elements, and a connecting bar thus leaving a recess for the lock bit rotatable by the cylinder core there is an integrally connected second housing part with a second axial bore running coaxially with the first axial bore, the cylinder core containing a key channel running in the longitudinal direction for receiving a key provided with incisions and further tumbler elements which, together with the tumbler elements accommodated in the first housing part, result in the rotational mobility of the cylinder core enabling release position are to be moved.

Derartige Profilschließzylinder sind für Sicherheitsschlösser allgemein bekannt, und zwar sowohl in sogenannter Halbzylinder- als auch Doppelzylinder-Form. Im ersteren Falle ist das zweite Gehäuseteil axial sehr kurz ausgebildet und seine entsprechend kurz gehaltene Axialbohrung dient lediglich der besseren Lagerung des Schließbarts, während beim Doppelzylinder das zweite Gehäuseteil zur Aufnahme eines weiteren Zylinderkerns dient und entsprechend dem ersteren Gehäuseteil ausgebildet ist. In beiden Fällen verlaufen die in den beiden Gehäuseteilen vorhandenen Axialbohrungen koaxial zueinander und durchgehend glattwandig, ebenso wie die darin lagernden Zylinderkerne. Der zugehörige Schlüssel hat derart gestaltete Einschnitte, daß die zumeist aus Gehäusestiften und Kernstiften bestehenden Zuhaltungselemente mit Hilfe dieses Schlüssels entgegen der Federbelastung soweit verschoben werden, daß die Trennstellen zwischen je einem Gehäusestift und einem Kernstift mit der Trennfläche zwischen Zylinderkern und Zylindergehäuse übereinstimmen. Dann kann der Zylinderkern mit dem Schlüssel gedreht werden und der an dem Kern befindliche Schließbart betätigt das zugehörige Schloß entweder im Öffnungs- oder auch Schließsinne.Profile lock cylinders of this type are generally known for security locks, in both so-called half-cylinder and double-cylinder shapes. In the former case, the second housing part is made very short axially and its correspondingly short axial bore only serves to better support the locking bar, while in the double cylinder the second housing part serves to accommodate a further cylinder core and is designed in accordance with the former housing part. In both cases, the axial bores in the two housing parts run coaxially with one another and are continuously smooth-walled, just like the cylinder cores stored therein. The associated key has such incisions that the tumbler elements, which usually consist of housing pins and core pins, are shifted against the spring load with the help of this key to such an extent that the separation points between each housing pin and a core pin match the interface between the cylinder core and the cylinder housing. Then the cylinder core can be turned with the key and the lock bit located on the core actuates the associated lock either in the opening or closing direction.

Eine Methode, um das Schloß ohne zugehörigen Schlüssel gewaltsam zu öffnen, besteht darin, den Zylinderkern gewaltsam herauszuziehen, wodurch Zugang zum Schließbart geschaffen und damit eine Schloßöffnungsmöglichkeit erreicht wird. Dieses gewaltsame Herausziehen erfolgt beispielsweise mittels eines korkenzieherartigen Schneidorgans, beispielsweise einer Schraube, die in den Schlüsselkanal eingeschraubt und dadurch mit dem Zylinderkern so fest verankert wird, daß dieser aus dem Zylindergehäuse herausgezogen werden kann. Bei diesem gewaltsamen Herausziehen werden die sperrenden Zuhaltungsstifte abgeschert. Das kann auch ein der axialen Festlegung des drehbaren Zylinderkerns im Zylindergehäuse dienender Sicherungsring nicht verhindern.One method of forcibly opening the lock without an associated key is to pull out the cylinder core by force, thereby creating access to the lock bit and thus opening the lock. This violent pulling out takes place, for example, by means of a corkscrew-like cutting element, for example a screw, which is screwed into the key channel and is thus firmly anchored to the cylinder core in such a way that it can be pulled out of the cylinder housing. During this violent pulling out, the locking tumbler pins are sheared off. This cannot be prevented by a circlip serving to axially fix the rotatable cylinder core in the cylinder housing.

Der Erfindung liegt die Aufgabe zugrunde, einen Profilschließzylinder mit zwei beidseitig eines Schließbarts koaxial angeordneten, einstückigen Gehäuseteilen unter Beibehaltung eines einfachen Aufbaus so zu verbessern, daß ein schlüsseleinsteckseitiges gewaltsames Herausziehen eines Zylinderkerns aus seinem Zylindergehäuseteil nicht möglich ist.The invention has for its object to improve a profile lock cylinder with two coaxially arranged on both sides of a locking bar, one-piece housing parts while maintaining a simple structure so that a key insertion side violent pulling out of a cylinder core from its cylinder housing part is not possible.

Diese Aufgabe wird dadurch gelöst, daß am ersten Gehäuseteil schlüsseleinsteckseitig ein radialer Ringvorsprung vor handen ist, der einen Teil der Stirnseite des Zylinderkerns übergreift, und daß der Zylinderkern durch die zweite Axialbohrung des zweiten Gehäuseteils hindurch in die erste Axialbohrung des ersten Gehäuseteils einbaubar ist.This object is achieved in that on the first housing part a radial annular projection is present on the key insertion side, which engages over part of the end face of the cylinder core, and in that the cylinder core can be installed through the second axial bore of the second housing part into the first axial bore of the first housing part.

Für die Erfindung ist also von Bedeutung, daß die Sicherung des Zylinderkerns gegen Herausziehen durch einen an ihm schlüsseleinsteckseitig vorhandenen Ringvorsprung erreicht wird. Das wiederum bedingt, daß der zu schützende Zylinderkern durch die im zweiten Gehäuseteil vorhandene, entsprechend größer zu bemessende zweite Axialbohrung hindurch in seine im ersten Gehäuseteil gelegene erste, im Durchmesser kleiner bemessene Axialbohrung eingeschoben werden kann. Der am Zylinderkern vorhandene Ringvorsprung kann in gewünschter Weise massiv ausgeführt werden. Da der Zylinderkern mit dem zugehörigen Zylindergehäuseteil von der Schließbartseite her zusammengebaut wird, kann der Ringvorsprung auch von daher bezüglich seiner Gestaltung ohne Rücksichtnahme auf den Einbauvorgang voll auf die Sicherheitsbedingungen abgestimmt gestaltet werden. Der Ringvorsprung kann beispielsweise auch aus Hartmetall bestehen.It is therefore important for the invention that the cylinder core is prevented from being pulled out by an annular projection provided on it on the key insertion side. This in turn means that the cylinder core to be protected can be inserted through the second axial bore, which is correspondingly larger in the second housing part, and into its first, smaller in diameter axial bore in the first housing part. The ring projection on the cylinder core can be made solid in the desired manner. Since the cylinder core with the associated cylinder housing part is assembled from the lockable side, the ring projection can therefore be designed with the safety conditions in mind, regardless of the installation process. The ring projection can also consist of hard metal, for example.

Der schlüsseleinsteckseitige Ringvorsprung kann ringsum geschlossen ausgebildet und der Schlüsselkanal schlüsselrükkenseitig von einem Steg ausgefüllt sein, dessen Höhe gleich der Höhe dieses Ringvorsprungs ist. Die ringsum geschlossene Ausbildung dieses Ringvorsprungs gewährleistet eine zusätzliche Auszugfestigkeit und bedingt einen schlüsselrückenseitig geschlossenen Schlüsselkanal, wozu ein Steg im Zylinderkern dient, mit dem die Gehäusestifte beim Drehen des Zylinderkerns niedergehalten werden. Der Steg ist mit dem Zylinderkern einstückig und im Steg gelegene Stiftbohrungsabschnitte sind vollständig ausgefüllt. Bei dieser Ausgestaltung des Zylinderkerns kann dieser in gewohnter Weise hergestellt werden, und auch die Herstellung der Bohrungen für die Stiftzuhaltungen braucht nicht geändert zu werden. Es ist beispielsweise möglich, diese Stiftbohrungen von oben durch das Zylindergehäuse und den Zylinderkern hindurch herzustellen und die nicht mehr benötigten Stiftbohrungsabschnitte z.B. zuzulöten.The ring projection on the key insertion side can be designed to be closed all around and the key channel on the key back side can be filled by a web, the height of which is equal to the height of this ring projection. The all-round closed design of this ring projection ensures additional pull-out strength and requires a key back closed key channel, for which a web in the cylinder core is used, with which the housing pins are held down when the cylinder core is turned. The web is in one piece with the cylinder core and pin bore sections located in the web are completely filled. With this configuration of the cylinder core, it can be produced in the usual way, and the production of the holes for the pin tumblers does not need to be changed either. It is possible, for example, to produce these pin bores from above through the cylinder housing and the cylinder core and, for example, to solder the pin bore sections that are no longer required.

Bei einer anderen Ausführungsform der Erfindung kann der Ringvorsprung am ersten Zylindergehäuseteil zumindest vor dem den Schlüsselrücken aufnehmenden Abschnitt des Schlüsselkanals schlüsselbreit geschlitzt sein und der Schlüssel einen diesen Ringvorsprung beim Drehen des Zylinderkerns aufnehmenden Schlitz besitzen. Infolge des Schlitzes kann der Schlüsselkanal eine herkömmliche Größe haben und insbesondere oben offen sein, so daß der Schlüsselrücken beim Drehen des Zylinderkerns der Niederhaltung der Gehäusestifte dient.In another embodiment of the invention, the ring projection on the first cylinder housing part can be slit key width at least in front of the section of the key channel receiving the key back and the key can have a slot receiving this ring projection when the cylinder core rotates. As a result of the slot, the key channel can have a conventional size and, in particular, be open at the top, so that the back of the key serves to hold down the housing pins when the cylinder core is rotated.

Der in Fig. 1 dargestellte Schließzylinder 10 ist ein Halbzylinder etwa des Profils der Fig. 4. Der Schließzylinder 10 besitzt ein Zylindergehäuse 11, das aus einem ersten Gehäuseteil 11' und einem zweiten Gehäuseteil 11'' besteht, die über den Verbindungssteg 11''' miteinander verbunden sind. Im ersten Gehäuseteil 1' sind eine erste Axialbohrung 27 und ein darin axial unverschieblich lagernder Zylinderkern 12 enthalten. Im Verbindungssteg 11''' ist eine Gewindebohrung 13 für den Eingriff einer Befestigungsschraube vorhanden, mit der der Schließzylinder 10 in einem Schloßgehäuse festgelegt ist. Der Lagerung des Schließbarts 15 dienen beidseitig des Schließbarts 15 vorhandene Lagerringe 16, sowie auch die zweite Axialbohrung 33 im Schenkel 32 des zweiten Gehäuseteils 11''. Die Lagerung des Schließbarts 15, seine Ausbildung und sein Zusammenbau mit dem Zylinderkern 12 sind herkömmlich und infolgedessen nicht näher dargestellt.The locking cylinder 10 shown in FIG. 1 is a half cylinder approximately of the profile of FIG. 4. The locking cylinder 10 has a cylinder housing 11 which consists of a first housing part 11 'and a second housing part 11' 'which are connected via the connecting web 11' ' 'are connected. The first housing part 1 'contains a first axial bore 27 and a cylinder core 12 which is axially immovably mounted therein. In the connecting web 11 '' 'there is a threaded bore 13 for the engagement of a fastening screw, with which the locking cylinder 10 is fixed in a lock housing. The bearing of the locking bar 15 is provided with bearing rings 16 on both sides of the locking bar 15, and also the second axial bore 33 in the leg 32 of the second housing part 11 ″. The storage of the locking bar 15, its design and its assembly with the cylinder core 12 are conventional and are therefore not shown in detail.

Das Zylindergehäuseteil 11' weist eine Mehrzahl nebeneinander in einer Reihe angeordneter Stiftbohrungen 17 auf, die jeweils eine Feder 18 aufnehmen, die sich mit einem Ende am Bohrungsboden 19 und mit dem anderen Ende an einem Gehäusestift 20 abstützt. Der Gehäusestift 20 überträgt die Kraft der Feder 18 auf einen Kernstift 21, der in einen Schlüsselkanal 22 des Zylinderkerns 12 hineinragt.The cylinder housing part 11 'has a plurality of pin bores 17 arranged side by side in a row, each of which receives a spring 18 which is supported at one end on the bore bottom 19 and at the other end on a housing pin 20. The housing pin 20 transmits the force of the spring 18 to a core pin 21 which projects into a key channel 22 of the cylinder core 12.

Der Schlüsselkanal 22 nimmt den Schlüsselschaft 23 des Schlüssels 24 auf, so daß dessen Schlüsseleinschnitte 25 in eine vorbestimmte Stellung zu den Kernstiften 21 gelangen. Da die Kernstifte 21 unterschiedlich lang ausgebildet sind und die Tiefe der Schlüsseleinschnitte 25 speziell auf die unterschiedliche Länge der Kernstifte 21 abgestimmt ist, werden diese vom Schlüsselschaft 23 bzw. von dessen Schlüsseleinschnitten 25 schlüsselseitig in der aus Fig. 1 ersichtlichen Weise unterschiedlich hoch gehalten, jedoch so, daß die Kernstifte 21 gehäusestiftseitig axial gleichweit vorspringen und insbesondere mit dem Außenumfang des Zylinderkerns 12 abschließen. Infolgedessen schließen auch die kernstiftseitigen Enden 26 der Gehäusestifte 20 mit dem Innenumfang der den Zylinderkern 12 drehbeweglich lagernden Bohrung 27 des Zylindergehäuses 11 ab, so daß der Zylinderkern 12 mit Hilfe des Schlüssels 24 gedreht werden kann, was infolge seiner drehfesten Verbindung mit dem Schließbart 15 zu dessen Drehung und damit zu einer Schloßbetätigung führt.The key channel 22 receives the key shaft 23 of the key 24, so that its key incisions 25 reach the core pins 21 in a predetermined position. Since the core pins 21 are of different lengths and the depth of the key incisions 25 is specifically matched to the different length of the core pins 21, these are held at different heights by the key shaft 23 or by the key incisions 25 on the key side in the manner shown in FIG. 1, however so that the core pins 21 on the housing pin side Project axially equally far and, in particular, complete with the outer circumference of the cylinder core 12. As a result, the core pin-side ends 26 of the housing pins 20 also terminate with the inner circumference of the bore 27 of the cylinder housing 11 which rotatably supports the cylinder core 12, so that the cylinder core 12 can be rotated using the key 24, which due to its rotationally fixed connection to the lock bit 15 increases whose rotation and thus leads to a lock actuation.

Damit der Schlüssel 24 genau in die in Fig. 1 dargestellte Lage in den Schlüsselkanal 22 hineingesteckt werden kann, hat der Schlüssel 24 einen Einsteckanschlag 28 und der Querschnitt des Schlüssels 24 weist Schlüsselkerben 29 auf, so daß nur ein Schlüssel 24 mit einem durch die Kerben 29 bedingten Schaftprofil in den Schlüsselkanal 22 gesteckt werden kann. Das Profil des Schlüsselkanals 22 ist beispielsweise ähnlich dem des Kanals 22 der Fig. 4.So that the key 24 can be inserted exactly into the position shown in FIG. 1 in the key channel 22, the key 24 has an insertion stop 28 and the cross section of the key 24 has key notches 29, so that only one key 24 with one through the notches 29 conditional shaft profile can be inserted into the key channel 22. The profile of the key channel 22 is, for example, similar to that of the channel 22 in FIG. 4.

Schlüsseleinsteckseitig hat das Zylindergehäuseteil 11' einen Ringvorsprung 30, der ein Widerlager für den Einsteckanschlag 28 des Schlüssels 24 bildet und überdies verhindert, daß der Zylinderkern 12 entgegen der Einsteckrichtung des Schlüssels 24 gewaltsam herausgezogen werden kann. Der Ringvorsprung 30 verkleinert also den Durchmesser der Bohrung 27 des Zylindergehäuses 11. Infolgedessen muß der Zylinderkern 12 schließbartseitig in diese Bohrung 27 eingebaut werden, also in Fig. 1 von rechts nach links durch die im zweiten, axial kurz gehaltenen Gehäuseteil 11'' vorhandene Axialbohrung 33 hindurch.On the key insertion side, the cylinder housing part 11 'has an annular projection 30 which forms an abutment for the insertion stop 28 of the key 24 and moreover prevents the cylinder core 12 from being pulled out against the direction of insertion of the key 24 by force. The ring projection 30 thus reduces the diameter of the bore 27 of the cylinder housing 11. As a result, the cylinder core 12 must be installed in this bore 27 on the lockable side, that is to say in FIG. 1 from right to left through the axial bore present in the second axially short housing part 11 '' 33 through.

Infolge des Ringvorsprungs 30 ist der Rücken 35 des Schlüssels 24 nicht ganz so hoch, wie bei einem Schlüssel eines ringvorsprunglosen Schließzylinders. Infolgedessen ist der Schlüsselkanal 22 nicht vollständig durch den Schlüsselrücken 35 ausgefüllt, der infolgedessen auch nicht dafür sorgen kann, daß die Gehäusestifte 20 vom Schlüssel 24 bei dessen entsprechender Drehstellung niedergehalten werden. Infolgedessen ist der Schlüsselkanal 22 schlüsselrückenseitig von einem Steg 34 ausgefüllt, der den Schlüsselschaft 23 am Schlüsselrücken 35 führt. Außerdem dient der Steg 34 dazu, bei entsprechender Drehstellung des Schlüssels 24 die Gehäusestifte 20 niederzuhalten. Der Steg 34 wird mit dem Zylinderkern 12 einstückig hergestellt.As a result of the ring projection 30, the back 35 of the key 24 is not quite as high as in the case of a key of a locking cylinder without a ring projection. As a result, the key channel 22 is not completely through the Key back 35 filled, which consequently can not ensure that the housing pins 20 are held down by the key 24 at its corresponding rotational position. As a result, the key channel 22 is filled on the key back side by a web 34 which guides the key shaft 23 on the key back 35. In addition, the web 34 serves to hold down the housing pins 20 when the key 24 is in a corresponding rotational position. The web 34 is produced in one piece with the cylinder core 12.

Zusätzliche Sicherheit gegen gewaltsames Herausziehen des Zylinderkerns 12 bietet der schließbartseitig an ihm vorhandene Ringvorsprung 31, mit dem der Zylinderkern in eine entsprechende, nicht näher bezeichnete Ringnut des Zylindergehäuseteils 11' eingreift, so daß er die gewünschte Lage einnimmt, in der seine Kernstifte 21 mit den Gehäusestiften 20 fluchten. Dieser Ringvorsprung 31 kann im Gegensatz zum außenliegenden Ringvorsprung 30 am Gehäuseteil 11' durch Unbefugte nicht erreicht und damit auch nicht etwa von außen aufgebohrt werden. Sein Einsatz erfordert, daß die im zweiten Gehäuseteil 11'' bzw. im Schenkel 32 vorhandene Axialbohrung 33 einen Durchmesser aufweist, der mindestens gleich dem Außendurchmesser des Ringvorsprungs 31 ist, um den Zylinderkern 12 mit dem Ringvorsprung 31 durchstecken zu können. Eine derartig bemessene Bohrung 33 ist bei dem in Fig. 1 dargestellten Profil-Halbzylinder unproblematisch. Bei einem Profil-Doppelzylinder kommt hinzu, daß dann auch der darin einzubauende zweite Zylinderkern einen entsprechend größeren Durchmesser besitzen muß.Additional security against violent pulling out of the cylinder core 12 is provided by the ring projection 31 on the closable side thereof, with which the cylinder core engages in a corresponding, not specified ring groove of the cylinder housing part 11 ', so that it assumes the desired position in which its core pins 21 with the Align housing pins 20. In contrast to the external annular projection 30 on the housing part 11 ′, this annular projection 31 cannot be reached by unauthorized persons and therefore cannot be drilled out from the outside. Its use requires that the axial bore 33 present in the second housing part 11 ″ or in the leg 32 has a diameter which is at least equal to the outer diameter of the ring projection 31 in order to be able to insert the cylinder core 12 with the ring projection 31. Such a dimensioned bore 33 is unproblematic in the profile half cylinder shown in FIG. 1. In the case of a profile double cylinder, the second cylinder core to be installed must also have a correspondingly larger diameter.

Die Stiftbohrungen 17 sind lediglich zu einem Teil durch eine Feder 17, einen Gehäusestift 20 und einen Kernstift 21 belegt. Sie werden hergestellt, indem beispielsweise in Richtung b durch das Zylindergehäuseteil 11' und den Zylinderkern 12 hindurchgebohrt wird. Die dabei entstehenden Bohrungsabschnitte 36 im Zylindergehäuseteil 11' und 37 im Zylinderkern 12 oberhalb des Schlüsselrückens 35 müssen geschlossen werden, damit die Kernstifte 21 beim Drehen des Kerns 12 nicht in offene Bohrungsabschnitte 36 des Zylindergehäuses 11 bzw. damit die Gehäusestifte 20 nicht in offene Bohrungsabschnitte 37 des Zylinderkerns 12 gelangen und dessen Weiterdrehen verhindern. Dieses Ausfüllen der betreffenden Bohrungsabschnitte 36, 37 erfolgt beispielsweise durch Zulöten.The pin bores 17 are only partially occupied by a spring 17, a housing pin 20 and a core pin 21. They are made by, for example is drilled in the direction b through the cylinder housing part 11 'and the cylinder core 12. The resulting bore sections 36 in the cylinder housing part 11 'and 37 in the cylinder core 12 above the key spine 35 must be closed so that the core pins 21 do not turn into open bore sections 36 of the cylinder housing 11 when the core 12 is rotated, and thus the housing pins 20 do not enter open bore sections 37 of the cylinder core 12 and prevent its further turning. This filling of the relevant bore sections 36, 37 takes place, for example, by soldering.

Der in den Fig. 2 bis 4 zur Hälfte dargestellte Doppelzylinder besteht im wesentlichen aus denselben Bauteilen wie der Halbzylinder der Fig. 1. Wesentlich ist hier jedoch, daß der schlüsseleinsteckseitige Ringvorsprung 30 einen Schlitz 38 hat, so daß der Schlüsselrücken 23 eine übliche Höhe hat und durch den Ringvorsprung 30 ungehindert in den Schlüsselkanal 22 eingesteckt werden kann. Da der Schlüssel 24 von der Einsteckstellung ausgehend jedoch nicht gedreht werden könnte, weil der Ringvorsprung 30 dies verhindern würde, ist der Schlüssel 24 mit einem Schlitz 39 versehen, dessen Tiefe und Breite auf die Höhe und Breite des Ringvorsprungs 30 abgestimmt sind.The half cylinder shown in FIGS. 2 to 4 consists essentially of the same components as the half cylinder of FIG. 1. However, it is essential here that the ring projection 30 on the key insertion side has a slot 38, so that the key back 23 has a customary height and can be inserted unhindered into the key channel 22 by the ring projection 30. However, since the key 24 could not be rotated from the inserted position because the ring projection 30 would prevent this, the key 24 is provided with a slot 39, the depth and width of which are matched to the height and width of the ring projection 30.
