Die Gehäuse der bekannten Zylinderschlösser bestehen aus einem Stück und werden in bestimmten Normlängen entsprechend der handelsüblichen Türstärken hergestellt. Dies ergibt in der Praxis eine Vielzahl von Zylinderlängen und den großen Nachteil für den Kunden, zum Zeitpunkt der Zylinder-(Schließanlagen-)bestellung bereits das genaue Maß der Türstärke samt Beschlag definitiv bekanntgeben zu müssen. Ein Unter-oder überschreiten dieser Maße um mehr als 2 mm stellt ein akutes Sicherheitsrisiko dar. Bestimmte Zylinderlängen sind derart selten (bezogen auf Stückzahlen), so daß sie als Sonderlängen erst zum Zeitpunkt der Kundenbestellung von Grund auf gefertigt werden müssen. Es sind somit in der Regel nur die häufigsten Zylinderlängen als Rohteile lagerhaltig. Dies führt zu sehr langen Lieferzeiten bzw. zum Einbau von "ungefähr passenden" Zylindern und somit zu einem erhöhten Sicherheitsrisiko: Jeder Unbefugte kann mittels Aufbruchwerkzeugen den vorstehenden Zylinder abbrechen bzw. herausreißen und so die Tür leicht öffnen.The housing of the well-known cylinder locks consist of one piece and are manufactured in certain standard lengths according to the standard door thicknesses. In practice, this results in a large number of cylinder lengths and the great disadvantage for the customer that when the cylinder (locking system) is ordered, the exact dimensions of the door thickness including the fitting must definitely be announced. Falling below or exceeding these dimensions by more than 2 mm represents an acute safety risk. Certain cylinder lengths are so rare (in terms of quantities) that they only have to be manufactured from the ground up as special lengths when the customer orders. As a rule, only the most common cylinder lengths are kept in stock as raw parts. This leads to very long delivery times and the installation of "approximately matching" cylinders and thus to an increased security risk: everyone Unauthorized persons can break off or tear out the protruding cylinder using break-open tools and thus easily open the door.

Der Erfindung liegt vornehmlich die Aufgabe zugrunde, Zylinderschlösser zu schaffen, die verschiedenen Türwanddicken angepaßt werden können.The invention is based primarily on the task of creating cylinder locks which can be adapted to different door wall thicknesses.

Erfindungsgemäß besteht der Schließzylinder aus zwei Teilen, insbesondere Hälften, deren Achsen fluchten und deren Abstand veränderbar ist. Dabei sind bevorzugt die Zylinderteile verschiebbar und feststellbar auf Tragelementen, z.B. einer Schiene, angeordnet. Auf diese Weise ist ein Zylinderschloß ohne Schwierigkeiten an verschiedene Anwendungsmöglichkeiten, insbesondere Türen, anpaßbar.According to the invention, the locking cylinder consists of two parts, in particular halves, the axes of which are aligned and the distance between which can be changed. The cylinder parts are preferably displaceable and lockable on support elements, e.g. a rail, arranged. In this way, a cylinder lock can be easily adapted to various applications, in particular doors.

Eine günstige Realisierung der Erfindung kann darin bestehen, daß das Zylindergehäuse aus zwei, vorzugsweise mindestens annähernd gegengleichen, Teilen besteht, in welchen je ein Zylinderkern drehbar gelagert ist und die Zylinderkerne durch eine längenverstellbare Drehverbindung verbunden sind, auf der die Schloß-Sperrnase, bevorzugt verschiebbar, sitzt. Auf diese Weise läßt sich die Entfernung der Endflächen der Gehäuseteile des Zylinders an die Dicke einer Türwand gut anpassen. Dazu ergibt sich eine besonders günstige praktische Ausbildung nach der Erfindung, wenn die Enden der Drehverbindung, auf der die Sperrnase verschiebbar sitzt, in die Zylinderkerne verschiebbar eingreifen, wobei zur Drehmitnahme Drehmitnehmer angeordnet sind und zweckmäßigerweise die Drehverbindung zwischen den Zylinderkernen aus einer Hohlachse mit zylindrischer Mantelfläche besteht, deren Enden in Bohrungen der Zylinderkerne passen und darin verschiebbar sind.A favorable implementation of the invention can consist in the fact that the cylinder housing consists of two, preferably at least approximately the same, parts, in each of which a cylinder core is rotatably mounted and the cylinder cores are connected by a length-adjustable rotary connection on which the lock locking lug, preferably displaceable , sits. In this way, the distance of the end faces of the housing parts of the cylinder can be adapted well to the thickness of a door wall. This results in a particularly favorable practical design according to the invention when the ends of the rotary connection on which the locking lug is displaceably engage in the cylinder cores, with rotary drivers being arranged for driving rotation and expediently the rotary connection between the cylinder cores from a hollow axis with a cylindrical lateral surface exists, the ends of which fit into the bores of the cylinder cores and can be moved therein.

Eine weitere Ausführungsvariante nach der Erfindung kann darin bestehen, daß die Drehverbindung zwischen den Zylinderkernen aus einer Hohlachse mit U-förmiger Mantelfläche besteht, deren Enden in U-förmige Ausfräsungen der Zylinderkerne passen und darin verschiebbar sind. Damit ergibt sich eine besonders wirksame Drehverbindung und somit Drehmitnahme der Sperrnase.A further embodiment variant according to the invention can consist in the fact that the rotary connection between the cylinder cores consists of a hollow axis with a U-shaped lateral surface, the ends of which fit into U-shaped millings of the cylinder cores and are displaceable therein. This results in a particularly effective rotary connection and thus rotary driving of the locking lug.

Gemäß einer weiteren Ausgestaltung der Erfindung sind die auf der Drehverbindung verschiebbaren Teile des Zylindergehäuses durch eine Verbindungsstange verbunden, deren Enden in Bohrungen der Gehäuseteile verschiebbar hineinragen und in der Verbindungsstange sind eine Gewindebohrung zur Befestigung des Zylinderschlosses in der Tür und Schraubverbindungen zur Fixierung der Entfernung zwischen den Endflächen der Zylindergehäuseteile angeordnet. Hiemit läßt sich trotz der Einstellbarkeit der Zylinderlänge eine sehr stabile Konstruktion erreichen. Eine besonders günstige Einstellbarkeit ergibt sich, wenn die auf der Drehverbindung verschiebbaren Teile des Zylindergehäuses durch eine Verbindungsstange verbunden sind, an deren einem Ende ein Rechtsgewinde und an deren anderem Ende ein Linksgewinde angeordnet ist, welche Gewinde in Gewindebohrungen der Zylindergehäuseteile zwecks Fixierung der Schloßlänge einschraubbar sind.According to a further embodiment of the invention, the parts of the cylinder housing which are displaceable on the rotary connection are formed by a Connecting rod connected, the ends of which protrude slidably into bores of the housing parts and in the connecting rod, a threaded bore for fastening the cylinder lock in the door and screw connections for fixing the distance between the end faces of the cylinder housing parts are arranged. This enables a very stable construction to be achieved despite the adjustability of the cylinder length. A particularly favorable adjustability results if the parts of the cylinder housing which are displaceable on the rotary connection are connected by a connecting rod, at one end of which a right-hand thread is arranged and at the other end of which a left-hand thread is arranged, which threads can be screwed into the threaded bores of the cylinder housing parts in order to fix the lock length .

Eine weitere Variante der Erfindung zeichnet sich dadurch aus, daß eine hohle Achse, die die Sperrnase trägt, mit den beiden Schließzylinderteilen längsverschiebbar verbunden ist, wobei jene Achse mit den Enden in Hohlräume von Kernen der Zylinderteile reicht und der Querschnitt des Außenmantels dieser Achse und der Querschnitt dieser Hohlräume mit Ausnahme des erforderlichen Spielraumes weitestgehend übereinstimmend unrund, z.B. oval oder zahnradartig, ausgebildet sind. Hiemit läßt sich einerseits eine gute Verschiebbarkeit der Schließzylinderteile bzw. der Zylinderkerne sowie der Sperrnase erreichen, anderseits aber auch eine rutschfeste Drehverbindung zwischen Sperrnase und hohler Achse sicherstellen. Zusätzlich kann bei Verwendung der Erfindung bei durch Microcomputer gesteuerten Sperrsystemen in der hohlen Achse bzw. in der Drehverbindung ein Microcomputer und ein Speicher für Sperrvorschriften angeordnet sein.Another variant of the invention is characterized in that a hollow axis, which carries the locking lug, is connected to the two locking cylinder parts in a longitudinally displaceable manner, the axis extending with ends in cavities of cores of the cylinder parts and the cross section of the outer shell of this axis and the The cross-section of these cavities is largely non-circular with the exception of the required margin, for example oval or gear-like, are formed. In this way, on the one hand, a good displaceability of the locking cylinder parts or the cylinder cores and the locking lug can be achieved, but on the other hand also ensure a non-slip rotary connection between the locking lug and the hollow axis. In addition, when the invention is used in the case of locking systems controlled by microcomputers, a microcomputer and a memory for locking instructions can be arranged in the hollow axis or in the rotary connection.

Vorteilhaft dienen zwecks Verstellung bzw. Lagesicherung der Sperrnase auf der Drehverbindung, vorteilhaft abnehmbare, Distanzklemmen od.dgl.Advantageously, for the purpose of adjusting or securing the locking lug on the rotary connection, advantageously removable, distance clamps or the like.

Die Erfindung wird an Hand von in der Zeichnung dargestellten Ausführungsbeispielen beschrieben.The invention is described with reference to exemplary embodiments shown in the drawing.

Die Figuren 16 und 17 zeigen hiezugehörige Querschnitte nach den Ebenen C-C bzw. D-D der Fig. 15 (wieder etwas vergrößert).1 and 2 show the cylinder lock in the locked position in a side view or end view, partly in section, FIGS. 3 and 4 the rotary connection and its cross section partly in section, 5 the profile of the locking lug, FIG. 6 the profile of the spacer clamps, FIGS. 7 to 9 sections through the cylinder core, FIGS. 10 and 11 a second embodiment of the connecting rod in side view or in section, FIG. 12 the cross section of a second embodiment of the Hollow axis in the cylinder core, FIGS. 13 and 14 cross sections according to the planes AA and BB of FIG. 1 (somewhat enlarged) and FIG. 15 a further embodiment variant in a schematic representation, partly in section. FIGS. 16 and 17 show associated cross sections along the planes CC and DD of FIG. 15 (again somewhat enlarged).

Wie die Fig. 1 zeigt, besteht das Zylinderschloß aus zwei mindestens annähernd gegengleichen Zylindergehäuseteilen 1 und 2, in welchen je ein Zylinderkern 3 drehbar gelagert und mittels Stift 4 in bekannter Weise gegen Herausziehen gesichert ist. Der Gehäuseteil 1 sitzt im Bereich der äußeren Türwand (nicht dargestellt), der Gehäuseteil 2 im Bereich der inneren Türwand, und entspricht der Entfernung zwischen den Endflächen 1′,2′ der Stärke (Dicke) der Türwand mit Beschlägen. Zur Befestigung des Zylinderschlosses in der Türwand ist in bekannter Weise eine Gewindebohrung 5 vorgesehen. Zur Betätigung des Sperriegels im Türschloß dient die mittels der Zylinderkerne 3 drehbar gelagerte Sperrnase 6.1 shows, the cylinder lock consists of two at least approximately opposite cylinder housing parts 1 and 2, in each of which a cylinder core 3 is rotatably mounted and secured in a known manner by means of pin 4 against pulling out. The housing part 1 sits in the area of the outer door wall (not shown), the housing part 2 in the area of the inner door wall, and corresponds to the distance between the end faces 1 ', 2' of the thickness of the door wall with fittings. A threaded bore 5 is provided in a known manner for fastening the cylinder lock in the door wall. The locking lug 6, which is rotatably mounted by means of the cylinder cores 3, serves to actuate the locking bolt in the door lock.

Um die Entfernung der Endflächen 1′,2′ der Gehäuseteile an die Dicke (Stärke) der Türwand anzupassen, muß die Entfernung zwischen den Gehäuseteilen 1 und 2, sowie die Entfernung zwischen der Endfläche 1′ und der Gewindebohrung 5 und auch der Sperrnase 6 veränderbar sein. Um dies zu erreichen, sind die Zylinderkerne 3 durch eine Drehverbindung verbunden, auf der die Sperrnase 6 verschiebbar sitzt, wobei für die Verstellung bzw. Sicherung der Lage der Sperrnase 6 von der Drehverbindung 7,7′ abnehmbare Distanzklemmen 22 dienen. Die Drehverbindung besteht aus einer Hohlachse 7 mit zylindrischer Mantelfläche 7′ (Fig. 4), deren Enden 7˝,7˝′ in den Bohrungen 3′,3˝ der Zylinderkerne 3 passen und darin verschiebbar sind.To adjust the distance of the end faces 1 ', 2' of the housing parts to the thickness (thickness) of the door wall, the distance between the housing parts 1 and 2, and the distance between the end face 1 'and the threaded bore 5 and the locking lug 6 can be changed be. In order to achieve this, the cylinder cores 3 are connected by a rotary connection on which the locking lug 6 is slidably seated, for the adjustment or securing of the position of the locking lug 6 from the rotary connection 7,7 'removable spacers 22 are used. The rotary connection consists of a hollow axis 7 with a cylindrical outer surface 7 '(Fig. 4), the ends 7˝, 7˝' in the bores 3 ', 3˝ of the cylinder cores 3 and are movable therein.

Wie die Fig. 4 zeigt, besitzt das profil der Hohlachse 7 einen Schlitz 8 und wie Fig. 3 erkennen läßt, einen durchgehenden Hohlraum 9, in welchem beispielsweise bei Benutzung der Erfindung bei einem microcomputergesteuerten Sperrsystem für Schlösser gemäß der AT-PS 390 118 ein Microcomputer samt Speicher 10 eingeklebt ist. Vom Microcomputer führt eine dreiadrige Kabelwendel 11 (Fig. 3) zu den äußeren Schlüsselkontakten 12 und 13 (Fig. 2). Die Kabelwendel 14 ist fünfadrig und führt mit zwei Drähten zum Türmagneten 15 und mit drei Drähten zu den Schlüsselkontakten 12′ und 13′ (Fig. 1) des innen liegenden Zylinderkernes 3. Die Schlüsselkontakte 12 und 13 bzw. 12′ und 13′ sind in bekannter Weise vertieft in verschiedenen tiefen Bohrungen eingeklebt, in welche der Schlüssel mit seinen Elektronik- und Stromversorgungskontakten paßt. Die Tiefe, Ausformung und Anordnung dieser Schlüsselkontakte ist variabel, so daß die elektrische Verbindung nur mit passendem Schlüssel hergestellt werden kann bzw. ein verkehrtes Anstecken des Schlüssels verhindert.As FIG. 4 shows, the profile of the hollow axis 7 has a slot 8 and, as can be seen in FIG. 3, a continuous cavity 9, in which, for example, when using the invention in one microcomputer-controlled locking system for locks according to AT-PS 390 118 a microcomputer including memory 10 is glued. A three-wire cable helix 11 (FIG. 3) leads from the microcomputer to the outer key contacts 12 and 13 (FIG. 2). The cable coil 14 is five-wire and leads with two wires to the door magnet 15 and with three wires to the key contacts 12 'and 13' (Fig. 1) of the inner cylinder core 3. The key contacts 12 and 13 or 12 'and 13' are in known way deeply glued into various deep holes, in which the key fits with its electronics and power supply contacts. The depth, shape and arrangement of these key contacts is variable, so that the electrical connection can only be made with a suitable key or prevents the key from being inserted incorrectly.

Der Anker des Sperrmagneten 15 besitzt einen Fortsatz 16 (Fig. 3), welcher wie die Fig. 8 zeigt, in einer Bohrung 17 des Zylinderkernes 3 sitzt. Wird mit der (siehe z.B. AT-PS 390 118) Stromversorgung des Schlüssels über die Stromversorgungskontakte (Fig. 1,2) 12 und 12′ der Microcomputer 10 zum Lesen der Schlüsselidentifikation über die/den Elektronikkontakt(e) 13 und 13′ aktiviert und erkennt laut tabellarischer Vergleiche den Schlüssel als richtig, so wird auf elektronischem Wege die elektrische Verbindung zum Sperrmagneten 15 hergestellt. Dieser Sperrmagnet zieht den Fortsatz 16 in die Bohrung 17 zurück (Fig. 8,9!), so daß sein Ende nicht mehr über die Mantelfläche des Zylinderkernes 3 vorsteht, wonach der Zylinderkern 3 im Zylindergehäuse 2 (Fig. 1) verdreht werden kann. Die Bohrung 18 im Zylindergehäuse 2 ist etwas größer im Durchmesser als die Bohrung 17 im Zylinderkern 3, so daß der Fortsatz 16 in der in der Fig. 1 gezeichneten Sperrstellung leicht platz findet.The armature of the blocking magnet 15 has an extension 16 (FIG. 3), which, as shown in FIG. 8, is seated in a bore 17 in the cylinder core 3. With the (see eg AT-PS 390 118) power supply of the key via the power supply contacts (Fig. 1,2) 12 and 12 'of the microcomputer 10 for reading the key identification via the / the electronic contact (s) 13 and 13' activated and recognizes the key as correct according to tabular comparisons, the electrical connection to the blocking magnet 15 is established electronically. This locking magnet pulls the extension 16 back into the bore 17 (Fig. 8,9!), So that its end no longer protrudes over the outer surface of the cylinder core 3, after which the cylinder core 3 can be rotated in the cylinder housing 2 (Fig. 1). The bore 18 in the cylinder housing 2 is slightly larger in diameter than the bore 17 in the cylinder core 3, so that the extension 16 easily finds space in the locked position shown in FIG. 1.

Zur Drehmitnahme der Sperrnase 6 besitzt diese einen in den Schlitz 8 der Hohlachse 7 passenden Fortsatz 20 (Fig. 5!) und der Zylinderkern 3, wie die Figuren 7 und 8 zeigen, einen Drehmitnahmestift 21, der in die Bohrung 3˝ hineinragt und in den Schlitz 8 paßt.To take the locking lug 6 with rotation, it has a projection 20 (FIG. 5!) Which fits into the slot 8 of the hollow axle 7 and the cylinder core 3, as FIGS. 7 and 8 show, a rotary driving pin 21 which projects into the bore 3˝ and in the slot 8 fits.

Da das Türschloß nicht immer in der Mitte der Türwand sitzt, muß die Sperrnase auf die richtige Entfernung von der Endfläche 1′ eingestellt werden. Zum Fixieren der Seitenlage sind zwischen der Sperrnase 6 und den Zylindergehäuseteilen 1 und 2 Distanzklammern 22 (Fig. 6) angeordnet bzw. anordbar, welche in verschiedenen Dicken hergestellt sind. Diese Distanzklammern sind aus einem federnden Material, z.B. Kunststoff, Metall hergestellt und besitzen federnde Arme 22′ und eine in den Schlitz 8 der Hohlachse 7 passende Nase 23, so daß sie von der Hohlachse bei der Drehung mitgenommen werden.Since the door lock is not always in the middle of the door wall, the locking lug must be set to the correct distance from the end face 1 '. To fix the side position are between the locking lug 6 and the cylinder housing parts 1 and 2 spacers 22 (Fig. 6) arranged or can be arranged, which are made in different thicknesses. These spacers are made of a resilient material, such as plastic, metal and have resilient arms 22 'and a fitting in the slot 8 of the hollow axis 7 lug 23, so that they are carried along by the hollow axis during rotation.

Zum Einstellen der Entfernung der Gewindebohrung 5 (Fig.1,13,14) von der Endfläche 1′ ist eine in den Zylindergehäuseteilen 1 und 2 verschiebbare Verbindungsstange 25 mit zylindrischem Querschnitt vorgesehen, welche mit ihren Enden in Bohrungen 26,26′ der Zylindergehäuseteile paßt. Zum Fixieren der Einstellung sind in der Verbindungsstange 25 Gewindestifte 27 und 27′ vorgesehen, welche durch Schlitze 28 und 28′ in den Zylindergehäuseteilen 1,2 zugänglich sind.To adjust the distance of the threaded bore 5 (Fig.1,13,14) from the end face 1 'is in the cylinder housing parts 1 and 2 displaceable connecting rod 25 with a cylindrical cross section is provided, which fits with its ends in bores 26,26' of the cylinder housing parts . To fix the setting 25 setscrews 27 and 27 'are provided in the connecting rod, which are accessible through slots 28 and 28' in the cylinder housing parts 1,2.

Da der äußere Zylindergehäuseteil 1 bei dem in der Fig. 1 dargestellten Ausführungsbeispiel nur durch die Klemmreibung zwischen dem Gewindestift 27′ und der Bohrung 26′ in der Tür festgehalten ist, wäre es möglich, den Zylindergehäuseteil 1 mitsamt seinen Einbauten aus dem Schloß zu ziehen, wenn man mit einem zangenartigen Einbruchswerkzeug in die Bohrungen für die Schlüsselkontakte 11,12 eingreift. Es würde dann das Innere des Schlosses zugänglich, wonach das Türschloß geöffnet werden könnte.Since the outer cylinder housing part 1 is held in the embodiment shown in FIG. 1 only by the clamping friction between the setscrew 27 'and the bore 26' in the door, it would be possible to pull the cylinder housing part 1 together with its internals from the lock, if one engages in the bores for the key contacts 11, 12 with a pliers-like burglary tool. The interior of the lock would then be accessible, after which the door lock could be opened.

Es ist daher von Vorteil, das in den Zylindergehäuseteil 1 hineinragende Ende 25′ der Verbindungsstange 25 sowie die Bohrung 26′ mit einem Gewinde auszuführen, wonach der Gewindestift 27′ sowie der Schlitz 28′ entfällt. Außerdem wäre es vorteilhaft, den Mittelteil der Verbindungsstange 25 im Bereich der Gewindebohrung mit einem Sechskant auszuführen, was das Einschrauben der Verbindungsstange erleichtert. Es kann auch, wie in den Figuren 10 und 11 dargestellt, ein Vierkant angeordnet sein und das Gewindeende 25˝ mit Rechtsgewinde und das Gewindeende 25˝′ mit Linksgewinde ausgeführt sein (Fig. 10!).It is therefore advantageous that in the cylinder housing part 1 protruding end 25 'of the connecting rod 25 and the bore 26' with a thread, after which the grub screw 27 'and the slot 28' is omitted. In addition, it would be advantageous to design the central part of the connecting rod 25 with a hexagon in the area of the threaded bore, which makes it easier to screw in the connecting rod. It can also be arranged, as shown in Figures 10 and 11, a square and the thread end 25˝ with right-hand thread and the thread end 25˝ 'with left-hand thread (Fig. 10!).

Wird die Hohlachse 31 mit U-förmiger Mantelfläche, wie in Fig. 12 dargestellt, ausgeführt, so sitzen ihre Enden 31′ verschiebbar in einer U-förmigen Ausfräsung der Zylinderkerne 32. Die Drehmitnahme ist dadurch gesichert und es kann der Drehmitnahmestift 21 entfallen. Der Außenmantel der Hohlachse 31 ist zylindrisch ausgeführt und ist wie die Zylinderkerne 32 in den Zylindergehäuseteilen 1 und 2 drehbar gelagert. Die U-förmige Öffnung nimmt die Sperrnase 6, in diesem Fall durch den verbreiterten Fortsatz 20, mit.If the hollow shaft 31 with a U-shaped lateral surface, as shown in Fig. 12, executed, its ends 31 'are slidably in a U-shaped milling of the cylinder cores 32. The rotary drive is thereby secured and the rotary driving pin 21 can be omitted. The outer jacket of the hollow shaft 31 is cylindrical and, like the cylinder cores 32, is rotatably supported in the cylinder housing parts 1 and 2. The U-shaped opening takes the locking lug 6, in this case by the widened extension 20.

Es kann sowohl im Zylindergehäuseteil 1 als auch im Zylindergehäuseteil 2 ein Sperrmagnet 15 angeordnet sein. Der innere Sperrmagnet ist durch einen im Zylinderschloß steckenden Sperrstopschlüssel so sicherbar, daß das Schloß von außen nicht sperrbar ist.A blocking magnet 15 can be arranged both in the cylinder housing part 1 and in the cylinder housing part 2. The inner locking magnet can be secured by a locking stop key inserted in the cylinder lock so that the lock cannot be locked from the outside.

Gemäß dem weiteren Ausführungsbeispiel nach den Figuren 15 bis 17 besteht ein in der Länge variabler Schließzylinder wieder aus zwei unabhängigen Teilen, hier Hälften 111. Diese Teile bzw. Hälften sind durch die Stellschiene 107 und die hohle Achse 104 längenverschiebbar verbunden. Die temporäre Fixierung der Zylinderlänge erfolgt über den Fixierungsmechanismus 106, z.B. Schrauben, wobei Ausführungen gemäß Fig. 15 oder Fig. 16 möglich sind. Die Bohrung 108 in der Verbindungsschiene 107 dient zur Montage des Schließzylinders im Schloß und ist durch das Verschieben der Zylinderteile und der Verbindungsschiene 107 optimal auf die Montagebohrung des Schlosses abstimmbar. Das Fixieren und Ausrichten der Sperrnase 109 gemäß Erfordernis des Schlosses erfolgt mittels selbsthaftender Distanzscheiben(-teile) bzw. -plättchen 105 zweckmäßig unterschiedlicher Dicke. Die Zylinderkerne 110 sind wie bei herkömmlichen Zylindern außen rund. Der innere Hohlraum dieser Kerne ist unrund ausgebildet, um eine rutschfeste, jedoch in der Länge verschiebbare Drehverbindung durch die außen unrunde hohle Achse 104 zur Sperrnase 109 zu gewährleisten. Dabei stimmen der unrunde Querschnitt des Außenmantels der hohlen Achse und der unrunde Querschnitt des Hohlraums der Kerne - mit Ausnahme des erforderlichen Spiels -weitestgehend überein. Als unrunde Querschnitte kommen z.B. ovale (wie in Fig. 16 dargestellt) oder verzahnte Formen in Frage. Um die Längenverschiebung zu gewährleisten, müssen die Kabelverbindungen 102 für Stromversorgung und übertragung der Schlüsselidentifikation von den Strom- und Lesekontakten 101 für den Schlüssel zum Microcomputer 103 und Speicher für Sperrvorschriften überlängen aufweisen. Die durchgehende hohle Achse 104 ist innen so ausgebildet, daß die Aufnahme des Microcomputers mit Speicher 103 und eines elektromagnetischen Entriegelungsmechanismusses samt Verriegelungsmechanismus 112 möglich ist.According to the further exemplary embodiment according to FIGS. 15 to 17, a locking cylinder which is variable in length again consists of two independent parts, here halves 111. These parts or halves are connected in a displaceable manner in terms of length by the adjusting rail 107 and the hollow axis 104. The temporary fixation of the cylinder length takes place via the fixation mechanism 106, for example screws, designs according to FIG. 15 or 16 being possible. The bore 108 in the connecting rail 107 is used for mounting the lock cylinder in the lock and can be optimally matched to the mounting bore of the lock by moving the cylinder parts and the connecting rail 107. The locking lug 109 is fixed and aligned in accordance with the requirements of the lock by means of self-adhesive spacing disks (parts) or plates 105 of appropriately different thicknesses. As with conventional cylinders, the cylinder cores 110 are round on the outside. The inner cavity of these cores is non-circular in order to ensure a non-slip, but length-adjustable rotary connection through the non-circular hollow axis 104 to the locking lug 109. The non-circular cross-section of the outer shell of the hollow axis and the non-circular cross-section of the cavity of the cores largely match - with the exception of the required play. For example, oval (as shown in FIG. 16) or toothed shapes can be considered as non-circular cross sections. In order to ensure the length shift, the cable connections 102 for power supply and transmission of the key identification from the power and reading contacts 101 for the key to the microcomputer 103 and memory for blocking regulations must be excessively long. The continuous hollow axis 104 is formed inside so that the inclusion of the Microcomputers with memory 103 and an electromagnetic unlocking mechanism including locking mechanism 112 is possible.
