Abstract

Double profiled lock cylinders are equipped with two cylinder housings (1, 2) which each consist of a circular cylinder part (1', 2') containing a rotary-actuable core and its tumblers and of a web part (1'', 2'') projecting radially from this and which are connected positively and non-positively to one another by means of a connecting bridge (6) made of harder material, which bridges a locking-bit region (3) located between them and contains the face-plate screw bore (5) located level with said locking-bit region and which extends on both sides in recesses present in the web parts (1'', 2'') of the cylinder housings (1, 2) and is contoured according to the web-part profile. In order to connect the two cylinder housings (1, 2) to one another so that they are still secure against being broken off and choked off, the connecting bridge (6) has a continuously solid spine which extends, in its middle part entirely surrounding the face-plate screw bore (5), directly up to the locking-bit region (3).

Description

Die Erfindung bezieht sich auf einen Profil-Doppelschließzylinder mit zwei aus je einem einen drehbetätigbaren Kern und dessen Zuhaltungen enthaltenden Kreiszylinderteil und einem daraus radial vorspringenden Stegteil bestehenden Zylindergehäusen, die durch eine den zwischen ihnen liegenden Schließbartbereich überbrückende und die in dessen Höhe gelegene Stulpschraubenbohrung enthaltende, sich beiderseits in in den Stegteilen der Zylindergehäuse vorhandene Aussparungen erstreckende, dem Stegteilprofil entsprechend konturierte Verbindungsbrücke aus härterem Werkstoff form- und kraftschlüssig miteinander verbunden sind.The invention relates to a profile double lock cylinder with two circular cylinder parts, each consisting of a rotatable core and its tumblers and a radially projecting web part, consisting of a lock bridging area between them and containing the faceplate screw hole at its height connecting bridges made of harder material, which are contoured in accordance with the web part profile and which are contoured in accordance with the web part profile, are connected to one another in a positive and non-positive manner on both sides in recesses present in the web parts of the cylinder housing.

Profil-Doppelschließzylinder obiger Art sind z.B. durch die DE-PS 37 34 539 bekannt. Die die beiden einzelnen Zylindergehäuse miteinander verbindende und aus härterem Material als diese bestehende Verbindungsbrücke soll dafür sorgen, daß der Doppelschließzylinder im andernfalls stark abbruchgefährdeten Bereich seiner Stulpschraubenbohrung weniger leicht abgebrochen oder abgewürgt werden kann. Hierzu besteht die bei dem vorbekannten Doppelschließzylinder vorhandene Verbindungsbrücke aus einer die mit seitlichen Abflachungen versehenen Zylindergehäuse-Stegteile umgreifenden, U-förmig gebogenen Traverse, die im Bereich ihrer in den U-Schenkeln gegenüberliegend angeordneten Stulpschraubenbohrungen mit einer die beiden Schenkel verbindenden Verstärkung sowie in ihrem übrigen Bereich mit mehreren in axialem Abstand voneinander liegenden Erhebungen versehen ist, die in in den aussparungsabgeflachten Zylindergehäuse-Stegteilen vorhandene, querverlaufende Nuten eingreifen. Durch die formschlüssig ineinandergreifenden Nuten und Erhebungen wird hierdurch zwar eine vergleichsweise gute Auseinanderreißfestigkeit erzielt. Da jedoch die radiale Eingriffstiefe zwischen den Nuten und Erhebungen vergleichsweise gering ist und die U-förmige Traverse auch nur eine dünne Wandstärke besitzt, ist die Auf- bzw. Abbruchfestigkeit bei dieser Doppelschließzylinder-Verbindung immer noch recht begrenzt, zumal auch die Verstärkungen im Stulpschraubenbohrungsbereich der U-förmigen Traverse nur vergleichsweise wenig zur Festigkeitssteigerung beitragen.Profile double lock cylinder of the above type are known for example from DE-PS 37 34 539. The connecting bridge, which connects the two individual cylinder housings and is made of harder material than this, is intended to ensure that the double locking cylinder in the otherwise severely prone to demolition area of its faceplate screw hole can be broken off or stalled less easily. For this purpose, the connection bridge present in the known double lock cylinder consists of a U-shaped cross-member which surrounds the side flats of the cylinder housing web parts and which is in the area of its faceplate screw holes arranged opposite in the U-legs is provided with a reinforcement connecting the two legs and, in its remaining area, with a plurality of elevations which are axially spaced from one another and which engage in transverse grooves provided in the flattened-out cylinder web web parts. Due to the form-fitting interlocking grooves and elevations a comparatively good tear resistance is achieved. However, since the radial depth of engagement between the grooves and elevations is comparatively small and the U-shaped crossmember has only a thin wall thickness, the resistance to tampering and demolition is still quite limited with this double lock cylinder connection, especially since the reinforcements in the area of the faceplate screw hole area U-shaped crossbar only make a comparatively small contribution to increasing strength.

Der Erfindung liegt die Aufgabe zugrunde, einen Profil-Doppelschließzylinder der eingangs erwähnten Gattung zu schaffen, dessen beide Zylindergehäuse noch abbruch- und abwürgesicherer miteinander zu verbinden sind.The invention has for its object to provide a profile double lock cylinder of the type mentioned, the two cylinder housings can be connected to each other even more break-proof and secure against chipping.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die aus härterem Werkstoff bestehende Verbindungsbrücke einen durchgehend massiv ausgebildeten, in seinem mittleren, die Stulpschraubenbohrung voll umfassenden Teil bis unmittelbar an den Schließbartbereich heranreichenden Massivrücken besitzt.According to the invention, this object is achieved in that the connecting bridge, which is made of harder material, has a solid, continuous part, in its central part, which fully encompasses the faceplate screw bore, and which extends right up to the locking bit area.

Durch diese massive Ausbildung der Verbindungsbrücke insbesondere auch in ihrem allein durch die Stulpschraubenbohrung geschwächten mittleren Bereich wird eine große Verbindungsfestigkeit zwischen den Zylindergehäusen erzielt, bei zugleich sehr wirksamem Schutz gegen deren Ab- bzw. Aufbrechen oder Abwürgen.This massive design of the connecting bridge, particularly in its central area weakened solely by the faceplate screw bore, achieves a great connection strength between the cylinder housings, while at the same time providing very effective protection against breaking or breaking or stalling.

Vorteilhaft ist die Verbindungsbrücke mit auf ihrem Massivrücken beidendig aufragend angeordneten U-Schenkeln versehen, die die mit entsprechend hochgezogenen seitlichen Aussparungen versehenen Stegteile der Zylindergehäuse beidseitig umgreifen. Dabei reichen die zu beiden Seiten der Zylindergehäuse-Stegteile gelegenen Aussparungen und die darin hineinpassenden U-Schenkel an den Enden der Verbindungsbrücke vorteilhaft bis an die Kreiszylinderteile der Zylindergehäuse heran, so daß auch insoweit noch eine zusätzliche formschlüssige Abstütz-Verbindung zustandekommt. Insbesondere kann damit auch die Biegefestigkeit des Doppelschließzylinders noch entsprechend verbessert werden.The connecting bridge is advantageously provided with U-legs which are arranged on both sides of its solid back and which grip around the web parts of the cylinder housing provided with correspondingly raised lateral recesses on both sides. These are sufficient on both sides of the cylinder housing web parts located recesses and the fitting U-legs at the ends of the connecting bridge advantageously up to the circular cylinder parts of the cylinder housing, so that an additional form-fitting support connection comes about. In particular, the bending strength of the double lock cylinder can also be improved accordingly.

Nach einem anderem Merkmal der Erfindung kann die massiv ausgebildete Verbindungsbrücke aber auch mit zu beiden Seiten ihres Stulpschraubenbohrungsbereichs jeweils gegenüberliegend angeordneten seitlichen Abflachungen und dadurch gebildeten T-förmig profilierten Brückenenden versehen sein, mit denen sie in in dem Schließbart zugewandten Bereich der Zylindergehäuse-Stegteile von unten eingeschnittene T-förmige Aussparungen einschiebbar ist und dabei zwischen und hinter die beidseitig der Aussparungs-T-Schenkel verbliebenen, nach unten gerichteten Gabelschenkel der Zylindergehäuse-Stegteile greift. Durch das beidendige Hintergreifen der am Zylindergehäuse vorhandenen Gabelschenkel durch die T-förmig profilierten Enden der Verbindungsbrücke kann zusätzlich auch die axiale Ausreißfestigkeit wesentlich gesteigert werden, die andernfalls allein von Verbindungsstiften gewährleistet wird, die durch in der Verbindungsbrücke sowie in den Zylindergehäuse-Stegteilen deckungsgleich liegende Bohrungen hindurchgesteckt sind.According to another feature of the invention, the solidly designed connecting bridge can also be provided with lateral flats, which are arranged opposite each other on both sides of its faceplate screw bore area, and T-shaped profiled bridge ends, with which they can be seen from below in the area of the cylinder housing web parts facing the cam lock incised T-shaped recesses can be inserted and thereby grips between and behind the downward fork leg of the cylinder housing web parts that remains on both sides of the recess T-leg. By reaching behind both ends of the fork legs on the cylinder housing through the T-shaped ends of the connecting bridge, the axial pull-out strength can also be significantly increased, which would otherwise only be ensured by connecting pins that are congruent through holes in the connecting bridge and in the cylinder housing web parts are put through.

Schließlich sieht die Erfindung noch vor, daß die massiv ausgebildete, vorzugsweise aus zähhartem Werkstoff, insbesondere Chromnickelstahl bestehende Verbindungsbrücke beiderseits ihres mittleren, die Stulpschraubenbohrung enthaltenden Bereichs axial verschieden lang ausgebildete Abschnitte mit unterschiedlich langen U-Schenkeln oder seitlichen Abflachungen zur Aufnahme eines oder mehrerer Zylindergehäuse-Verlängerungsteile besitzt, die profilmäßig mit den Zylindergehäusen in deren die Aussparungen für die Verbindungsbrücke enthaltendem Bereich übereinstimmen. Auf diese Weise können also auch entsprechend verlängerte Zylindergehäuse unter Zuhilfenahme der massiven Verbindungsbrücke zusammengebaut werden.Finally, the invention also provides that the solidly constructed connecting bridge, preferably made of tough-hard material, in particular chromium-nickel steel, on both sides of its central region, which contains the faceplate screw bore, has sections of different lengths with different lengths of U-legs or lateral flats for receiving one or more cylinder housings. Has extension parts that match the profile of the cylinder housings in the area containing the recesses for the connecting bridge. In this way, correspondingly elongated cylinder housings can also be assembled with the aid of the massive connecting bridge.

Da die Verbindungsbrücke sich vorteilhaft jeweils nur bis etwa zur Mitte der Zylindergehäuse-Stegteile erstreckt, bleiben die äußeren Stirnenden der beiden Zylindergehäuse unverändert, so daß ein solcher Doppelschließzylinder das herkömmliche Aussehen besitzt. Auch können in den äußeren Bereichen der Zylindergehäuse-Stegteile ggfs. wie bei herkömmlichen Profilschließzylindern Zuhaltungsbohrungen mit darin befindlichen Federn und Zuhaltungsstiften untergebracht werden, wenngleich es sich wegen der übrigen, mit für die Brückenverbindung notwendigen Abflachungen versehenen Stegteilbereichen empfiehlt, die Zuhaltungen im Kreiszylinderteil der beiden Zylindergehäuse unterzubringen.Since the connecting bridge advantageously extends only up to approximately the middle of the cylinder housing web parts, the outer ends of the two cylinder housings remain unchanged, so that such a double locking cylinder has the conventional appearance. Also, as with conventional profile lock cylinders, tumbler bores with springs and tumbler pins located therein can be accommodated in the outer areas of the cylinder housing web parts, although it is advisable to use the tumblers in the circular cylinder part of the two cylinder housings because of the other web part areas with flats required for the bridge connection to accommodate.

Der in Fig.1 wiedergegebene Profil-Doppelschließzylinder besteht im wesentlichen aus den beiden Zylindergehäusen 1,2, die durch eine den zwischen ihnen liegenden Bereich 3 für den Schließbart 4 überbrückende und die in dessen Höhe gelegene Stulpschraubenbohrung 5 enthaltende Verbindungsbrücke 6 aus zähhartem Werkstoff form- und kraftschlüssig miteinander verbunden sind. Zwischen dem Schließbart 4 und dem Zylindergehäuse 2 ist noch ein letzterem entsprechend profiliertes Zylindergehäuse-Verlängerungsteil 7 angeordnet. Jedes Zylindergehäuse 1,2 besteht aus einem einen drehbetätigbaren Zylinderkern 8 und dessen nicht näher dargestellte Zuhaltungen enthaltenden Kreiszylinderteil 1' bzw. 2' und einem daraus radial vorspringenden Stegteil 1'' bzw. 2''.The profile double locking cylinder shown in FIG. 1 essentially consists of the two cylinder housings 1, 2, which are separated by a region 3 between them for the lock bit 4 bridging and containing the forend screw hole 5 located connecting bridge 6 made of tough hard material are positively and non-positively connected. Between the lock bit 4 and the cylinder housing 2 there is a cylinder housing extension part 7 which is profiled accordingly. Each cylinder housing 1, 2 consists of a circular cylinder part 1 'or 2' containing a rotatably actuatable cylinder core 8 and its tumblers, not shown, and a web part 1 '' or 2 '' projecting radially therefrom.

Die Verbindungsbrücke 6 besitzt, wie insbesondere die Fig.4 bis 6 erkennen lassen, einen durchgehend massiv ausgebildeten Rücken 6', der in seinem mittleren, die Stulpschraubenbohrung 5 enthaltenden Teil 6'' diese Bohrung 5 voll umfaßt und hier bis unmittelbar an den Schließbartbereich 3 heranreicht. Weiterhin ist die Verbindungsbrücke 6 mit auf ihrem Massivrücken 6' beidendig aufragend angeordneten U-Schenkeln 6''',6IV versehen. Diese umgreifen beidseitig die mit entsprechend hochgezogenen seitlichen Aussparungen bzw. Abflachungen 9 versehenen Stegteilpartien 1''' bzw. 2''' der Zylindergehäuse 1 bzw. 2. Diese Aussparungen 9 zu beiden Seiten der Zylindergehäuse-Stegteilbereiche 1''',2''' und die darin hinein passenden U-Schenkel 6''' bzw. 6IV an den Enden der Verbindungsbrücke 6 reichen bis an die Kreiszylinderteile 1' bzw. 2' der Zylindergehäuse 1 bzw. 2 heran, wie das insbesondere die Fig.1 und 2 wiedergeben.The connecting bridge 6, as can be seen in particular in FIGS. 4 to 6, has a continuously solid back 6 ', which in its central part 6''which contains the faceplate screw bore 5, completely surrounds this bore 5 and here directly to the lock bit area 3 reaches. Furthermore, the connecting bridge 6 is provided with U-legs 6 ''', 6 IV arranged on both sides of its solid back 6'. These engage on both sides of the web part parts 1 '''or2''' of the cylinder housing 1 or 2 provided with correspondingly raised lateral recesses or flats 9. These recesses 9 on both sides of the cylinder housing web part regions 1 ''',2'''and the matching U-legs 6''' or 6 IV at the ends of the connecting bridge 6 extend up to the circular cylinder parts 1 'or 2' of the cylinder housing 1 or 2, as is particularly the the Fig.1 and Play 2.

Die Verbindungsbrücke 6 besitzt, wie insbesondere Fig.2 und 5 zeigen, eine Außenkontur, die mit dem Profil der unabgeflachten Zylindergehäuse-Stegteile 1'' bzw. 2'' voll übereinstimmt, so daß sich außen ein bündiger Verlauf zwischen der Verbindungsbrücke 6 und den vorerwähnten Stegteilen 1'', 2'' ergibt. Zur axialen Verbindung dienen die Querstifte 10, die in deckungsgleich liegende Bohrungen 11 bzw. 12 in den Verbindungsbrücken-Schenkeln 6''',6IV bzw. den abgeflachten Stegteilen 1''' bzw. 2''' der Zylindergehäuse 1 bzw. 2 einsteckt bzw. eingetrieben sind. Vorteilhaft handelt es sich dabei um im Durchmesser entsprechend beschaffene Klemmstifte 10, an deren Stelle jedoch grundsätzlich auch andere Verbindungselemente, wie z.B. Nietstifte, Schrauben od.dgl. treten können.The connecting bridge 6, as shown in particular in FIGS. 2 and 5, has an outer contour that fully matches the profile of the unflattened cylinder housing web parts 1 ″ or 2 ″, so that there is a flush course between the connecting bridge 6 and the outside aforementioned web parts 1 '', 2 '' results. The transverse pins 10, which lie in congruent bores 11 and 12 in the connecting bridge legs 6 ''', 6 IV and the flattened web parts 1''' and 2 '''of the cylinder housings 1 and 2, serve for the axial connection inserted or driven. These are advantageously clamping pins 10 of corresponding diameter, but in their place, in principle, other connecting elements, such as rivet pins, screws or the like. can kick.

Das in Fig.3 links dargestellte Zylindergehäuse-Verlängerungsteil 7 stimmt profilmäßig mit den Zylindergehäusen 1, 2 in deren die Abflachungen 9 enthaltenden Stegbereichen 1''' bzw. 2''' überein. Es besitzt also gleichfalls ein Kreiszylinderteil 7' sowie ein daraus radial nach unten vorspringendes verkürztes Stegteil 7''. Es kann, wie Fig.1 zeigt, zusammen mit dem Zylindergehäuse 2 in die Verbindungsbrücke 6 eingesetzt bzw. damit verbunden werden. Die massiv ausgebildete Verbindungsbrücke besitzt zu diesem Zweck beiderseits ihres mittleren die Stulpschraubenbohrung 5 enthaltenden Bereichs 6'' axial verschieden lang ausgebildete Abschnitte 6V,6VI mit daran sitzenden unterschiedlich langen U-Schenkeln 6''' bzw. 6IV. Insgesamt erstreckt sich die Verbindungsbrücke 6 jeweils bis etwa zur Mitte der Zylindergehäuse-Stegteile 1'' bzw. 2''. Dadurch können in deren unverkürzt gebliebenen äußeren Bereichen gegebenenfalls auch herkömmliche Zuhaltungsbohrungen mit darin befindlichen Zuhaltungsfedern und Stiften untergebracht werden. Wegen der im übrigen verkürzten Ausbildung der Stegteile empfiehlt es sich jedoch, die Zuhaltungselemente und deren sie aufnehmende Bohrungen mit den entsprechend darin unterzubringenden Federn ausschließlich im Bereich der Kreiszylinderteile 1' bzw. 2' unterzubringen, wie das beispielsweise bei den Schließzylindern nach der deutschen Patentanmeldung P 40 00 179 der Fall ist.The cylinder housing extension part 7 shown on the left in FIG. 3 corresponds in profile to the cylinder housings 1, 2 in their web regions 1 ″ ″ or 2 ″ ″ containing the flattened portions 9. It also has a circular cylinder part 7 'and a shortened web part 7''projecting radially downward therefrom. As shown in FIG. 1, it can be inserted or connected to the connecting bridge 6 together with the cylinder housing 2. For this purpose, the solidly designed connecting bridge has sections 6 V , 6 VI of axially different lengths, with axially different lengths, with U-legs 6 '''and 6 IV of different lengths attached to them, on both sides of their central region 6''which contains the forend screw bore 5. Overall, the connecting bridge 6 extends up to approximately the middle of the cylinder housing web parts 1 ″ or 2 ″. As a result, conventional tumbler bores with tumbler springs and pins located therein can also be accommodated in their undiminished outer regions. Because of the otherwise shortened design of the web parts, however, it is advisable to accommodate the tumbler elements and their bores with the springs to be accommodated therein only in the area of the circular cylinder parts 1 'or 2', as is the case, for example, with the locking cylinders according to German patent application P 40 00 179 is the case.

Wegen des durchgehend massiv ausgebildeten Rückens 6' der Verbindungsbrücke 6, die insbesondere auch die Stulpschraubenbohrung 5 sowohl umfangsmäßig als auch in axialer Richtung voll umfaßt und bis unmittelbar an den Schließbartbereich 3 heranreicht, wird eine große Aufbruch- bzw. Abbruchsicherheit gewährleistet, insbesondere wenn die Verbindungsbrücke 6 dafür aus besonders zähhartem Werkstoff, beispielsweise Chromnickelstahl besteht.Because of the continuously solid back 6 'of the connecting bridge 6, which in particular also completely encompasses the faceplate screw bore 5 both circumferentially and in the axial direction and reaches right up to the locking bit area 3, great security against break-in or break-off is ensured, especially when the connecting bridge 6 made of particularly tough material, for example chrome nickel steel.

Bei der in den Fig.7 bis 12 dargestellten Doppelschließzylinder-Version ist die Verbindungsbrücke gleichfalls mit einem durchgehend massiv ausgebildeten Rücken 6' versehen, der die Stulpschraubenbohrung 5 voll umfaßt und bis unmittelbar an den Schließbartbereich 3 heranreicht. Hier ist aber die Verbindungsbrücke 6 mit zu beiden Seiten ihres Stulpschraubenbohrungsbereichs 6'' jeweils gegenüberliegend angeordneten seitlichen Abflachungen 13 und dadurch gebildeten T-förmig profilierten Brückenenden 14 versehen, wohingegen in den Zylindergehäuse-Stegteilen in deren dem Schließbart zugewandt liegenden Bereichen T-förmige Aussparungen 15 von unten eingeschnitten sind, wobei die beidseitig dieser Aussparungs-T-Schenkel verbliebenen Stegteile nach unten gerichtete Gabelschenkel 16 bilden. Zwischen diese Gabelschenkel 16 und hinter sie, also in die quer durchgehenden Einschnitte 15' der T-förmigen Aussparungen 15, greifen die T-förmig profilierten Enden 14 der Verbindungsbrücke 6. Auf diese Weise wird die axiale Auszieh- bzw. Ausreißfestigkeit des Doppelschließzylinders noch wesentlich erhöht, wozu im übrigen aber auch im vorliegenden Fall die durch die deckungsgleichen Bohrungen 11' in der Verbindungsbrücke 6 und die Bohrungen 12' in den Gabelschenkeln 16 der Zylindergehäuse 1 bzw. 2 hindurchgesteckten Verbindungsstifte 10 beitragen. Wie Fig.8 zeigt, können einer oder ggfs. auch mehrere dieser Verbindungsstifte 10' ein- oder beidseitig über das Profil der Verbindungsbrücke 6 bzw. der Zylindergehäuse-Stegteile 1'',2'' hinausragen, wodurch die axiale Ausreiß- bzw. Ausziehfestigkeit noch weiter gesteigert werden kann, da die Vorsprünge dieser Verbindungsstifte 10' hinter die Schloßbeschläge greifen.In the double lock cylinder version shown in Figures 7 to 12, the connecting bridge is also provided with a continuously solid back 6 ', which fully encompasses the faceplate screw bore 5 and extends right up to the locking bit area 3. Here, however, the connecting bridge 6 is provided on both sides of its faceplate screw bore region 6 '' with opposite side flats 13 and T-shaped profiled bridge ends 14, whereas T-shaped recesses 15 in the cylinder housing web parts in their areas facing the lock bit are cut from below, the web parts remaining on both sides of this recess T-leg form downward-pointing fork legs 16. The T-shaped ends 14 of the connecting bridge 6 engage between these fork legs 16 and behind them, that is to say in the transverse incisions 15 ′ of the T-shaped recesses 15. In this way, the axial pull-out or pull-out strength of the double locking cylinder is still essential Increased, to the rest of the present case, the connecting pins 10 inserted through the congruent bores 11 'in the connecting bridge 6 and the bores 12' in the fork legs 16 of the cylinder housings 1 and 2 respectively. As shown in FIG. 8, one or, if necessary, also several of these connecting pins 10 'can protrude on one or both sides over the profile of the connecting bridge 6 or the cylinder housing web parts 1'',2'', whereby the axial pull-out or pull-out strength can be increased even further, since the projections of these connecting pins 10 'engage behind the lock fittings.

Auch im vorliegenden Fall besitzt das Verbindungsstück beidseitig seines Stulpschraubenbohrungsbereichs 6'' verschieden lang ausgebildete Abschnitte mit unterschiedlich langen Abflachungen 13, um auf diese Weise ein Zylindergehäuse-Verlängerungsteil 7 mit einbauen zu können. Dieses Verlängerungsteil 7 ist ebenso wie der zugehörige Schließzylinder 2 profiliert, insbesondere in seinem Stegteil 7'' gleichfalls mit verlängerten Gabelschenkeln 7''' versehen, die wie die Gabelschenkel 6 am Zylindergehäuse 2 den längeren abgeflachten Abschnitt der Verbindungsbrücke 6 bzw. ihres Massivrückens 6' beidseitig umgreifen.In the present case too, the connecting piece has sections of different lengths with flats 13 of different lengths on both sides of its faceplate screw bore region 6 ″, in order in this way to be able to install a cylinder housing extension part 7. This extension part 7, like the associated lock cylinder 2, is profiled, in particular in its web part 7 ″ also provided with extended fork legs 7 ″ ″, which like the fork legs 6 on the cylinder housing 2 have the longer flattened section of the connecting bridge 6 or its solid back 6 ′. reach around on both sides.

Wie insbesondere Fig.8 zeigt, ergibt sich auch in diesem Fall eine mit alleiniger Ausnahme des beidseitig vorstehenden Verbindungsstiftes 10 außen glatte Profilzylinderkontur zwischen den Zylindergehäusen und der sie miteinander verbindenden Massivbrücke 6.As shown in FIG. 8 in particular, this also results in a profile cylinder contour which is smooth on the outside, with the sole exception of the connecting pin 10 projecting on both sides, between the cylinder housings and the solid bridge 6 connecting them to one another.
