Description

Die Erfindung betrifft ein Verriegelungssystem mit Kontaktflächen, nämlich einerseits ein Verfahren zur Kodierung von Schlüssel und Schließstempel eines Schlosses eines Verriegelungssystems, und weiterhin ein dementsprechend ausgestaltetes Schloss eines Verriegelungssystems.The invention relates to a locking system with contact surfaces, namely on the one hand a method for coding the key and locking stamp of a lock of a locking system, and also a correspondingly designed lock of a locking system.

Ein gattungsgemäßes Verfahren ist aus der FR 2 877 974 A1 bekannt. Schlüssel und Schließstempel werden dabei jeweils mithilfe eines Grundkörpers hergestellt, dem jeweils zusätzlich ein separates Bauteil, nämlich das jeweilige Kodierteil, zugeordnet wird. Die Kodierteile von Schlüssel und Schließstempel passen komplementär zusammen, so dass mit dem Schlüssel der Schließstempel des Schlosses betätigt werden kann.A generic method is from the FR 2 877 974 A1 known. Key and locking stamp are each produced with the aid of a base body, to which a separate component, namely the respective coding part, is assigned. The coding parts of the key and the locking stamp fit together so that the locking stamp of the lock can be operated with the key.

Die Oberflächen beider Bauteile, wo ein Kodierteil einem Grundkörper anliegt, werden als Kontaktflächen bezeichnet, und diese zusammenwirkenden Kontaktflächen am Kodierteil einerseits und am Grundkörper andererseits sind geometrisch derartig ausgestaltet, dass sie eine Mehrzahl unterschiedlicher Drehstellungen ermöglichen, in welchem dasselbe Kodierteil wahlweise an dem Grundkörper angesetzt werden kann.The surfaces of both components, where a coding part rests on a base body, are referred to as contact surfaces, and these interacting contact surfaces on the coding part on the one hand and on the base body on the other hand are geometrically designed in such a way that they enable a plurality of different rotational positions in which the same coding part is optionally attached to the base body can be.

Die Kodierteile können also in einer kleinen Serie hergestellt werden und ergeben dadurch, dass sie in unterschiedlichen Drehstellungen an dem Grundkörper befestigt werden können, stets unterschiedlich ausgestaltete Schlüssel bzw. Schließstempel, denn das Verriegelungssystem ist derart ausgestaltet, dass der Schlüssel nur in einer vorbestimmten Ausrichtung an den Schließstempel herangeführt werden kann. Wenn zwei Schlüssel identische Kodierteile aufweisen, die jedoch in unterschiedlicher Drehwinkelstellung an ihren jeweiligen Grundkörpern montiert sind, kann nur einer dieser beiden Schlüssel zu dem zugehörigen Schließstempel passen, während der zweite Schlüssel keinen funktionsfähigen Schlüssel für diesen Schließstempel darstellt.The coding parts can therefore be produced in a small series and, because they can be fastened to the base body in different rotational positions, always differently designed keys or locking stamps, because the locking system is designed such that the key is only in a predetermined orientation the locking ram can be brought up. If two keys have identical coding parts, which are, however, mounted on their respective base bodies in a different angular position, only one of these two keys can fit the associated locking stamp, while the second key does not represent a functional key for this locking stamp.

Auch aus der WO 2012/062305 A2 ist ein gattungsgemäßes Verfahren bekannt. Dabei sind die Kodierteile jeweils als Kodierscheiben ausgestaltet.Also from the WO 2012/062305 A2 a generic method is known. The coding parts are each designed as coding disks.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren dahingehend zu verbessern, dass die Herstellung des Schlüssels und des Schließstempels vereinfacht wird und über diese Vereinfachung hinaus ein weiterer wirtschaftlicher Vorteil dadurch erzielbar ist, dass gleich ausgestaltete Kodierteile in einer möglichst großen Anzahl verwendet werden können und dabei gleichzeitig sicherstellen, dass jeweils nur eine einzige funktionsfähige Schließpaarung geschaffen wird. Weiterhin liegt der Erfindung die Aufgabe zugrunde, ein Schloss eines Verriegelungssystems anzugeben, bei dem Schlüssel und Schließstempel bei Verwendung möglichst weniger unterschiedlicher Bauteile zu einer möglichst großen Anzahl unterschiedlich kodierter Schließpaarungen angeordnet werden können.The present invention is based on the object of improving a generic method in such a way that the production of the key and the locking stamp is simplified and, in addition to this simplification, a further economic advantage can be achieved in that identically configured coding parts can be used in as large a number as possible and at the same time ensure that only a single functional pair of locks is created. Furthermore, the invention is based on the object of specifying a lock of a locking system in which the key and locking stamp can be arranged to form the largest possible number of differently coded lock pairings using as few different components as possible.

Diese Aufgabe wir durch ein Verfahren nach Anspruch 1 und ein Schloss nach Anspruch 9 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.This object is achieved by a method according to claim 1 and a lock according to claim 9. Advantageous refinements are described in the subclaims.

Die Erfindung schlägt mit anderen Worten ein Verfahren vor, bei dem die zusammenwirkenden Kontaktflächen, an denen ein Kodierteil an einem Grundkörper anliegt, nicht in dem Sinne kodiert sind, dass sie lediglich in wenigen vorbestimmten Drehstellungen miteinander verbindbar sind. Vielmehr sind Grundkörper und Kodierteil relativ zueinander stufenlos drehbar, so dass sie in nahezu beliebigen Drehstellungen relativ zueinander angeordnet werden können. Falls kein Anschlag vorgesehen ist, der diese Drehbewegung begrenzt, sind die beiden Bauteile um volle 360° frei gegeneinander drehbar. Falls jedoch ein Anschlag vorgesehen sein sollte, der diese Drehbewegung begrenzt, sind innerhalb des verfügbaren Drehwinkelbereichs stufenlos beliebig viele unterschiedliche Drehstellungen möglich. Jedenfalls kann vorschlagsgemäß eine Vielzahl unterschiedlich kodierter Schlüssel oder Schließstempel geschaffen werden, die sehr enge Abstufungen unterschiedlicher Drehstellungen zwischen Kodier- und Grundteil aufweisen, ohne dass hierzu eine hochpräzise feinmechanische Ausgestaltung der Kontaktflächen mit entsprechend fein gerasterter Profilierung erforderlich wäre.In other words, the invention proposes a method in which the interacting contact surfaces on which a coding part rests on a base body are not coded in the sense that they can only be connected to one another in a few predetermined rotational positions. Rather, the base body and the coding part can be rotated steplessly relative to one another, so that they can be arranged in almost any rotational positions relative to one another. If no stop is provided that limits this rotary movement, the two components can be freely rotated against each other through a full 360 °. If, however, a stop should be provided that limits this rotary movement, any number of different rotary positions are possible within the available rotary angle range. In any case, according to the proposal, a large number of differently coded keys or locking stamps can be created that have very narrow gradations of different rotational positions between the coding and base part without the need for a highly precise, fine mechanical design of the contact surfaces with correspondingly finely rasterized profiling.

In einer fertigungstechnisch möglichst einfachen und somit wirtschaftlichen Ausgestaltung kann vorgesehen sein, dass die Kontaktflächen glattflächig ausgestaltet sind. Es kann jedoch auch vorgesehen sein, dass eine Kontaktfläche profiliert und die gegenüberliegende Kontaktfläche glatt ausgestaltet ist, so dass auch bei dieser Ausgestaltung das Kodierteil gegenüber dem Grundkörper beliebig verdreht werden kann und sich insofern keine Drehbehinderung der beiden Kontaktflächen ergibt, welche die möglichen Drehwinkelstellungen der beiden Bauteile zueinander einschränken würde. Gegebenenfalls können sogar beide Bauteile profiliert sein, wenn dies nicht zu einer Einschränkung ihrer Drehbeweglichkeit relativ zueinander führt. So kann beispielsweise an einer Kontaktfläche eine strahlenförmige, radiale Riffelung vorgesehen sein und an der anderen Kontaktfläche eine kreisförmige konzentrische Riffelung, so dass diese beiden in unterschiedlichen Richtungen verlaufenden Profilierungen nicht zu einer Verzahnung des Kodierteils an dem Grundkörper führen und dementsprechend die Drehbeweglichkeit zwischen diesen beiden Bauteilen nicht eingeschränkt ist. Diese Profilierungen vergrößern die Oberfläche der jeweiligen Kontaktfläche und können daher aus anderen Gründen vorteilhaft sein, wie weiter unten noch erläutert wird.In an embodiment that is as simple as possible in terms of production engineering and thus economical, it can be provided that the contact surfaces are designed with smooth surfaces. However, it can also be provided that one contact surface is profiled and the opposite contact surface is smooth, so that in this configuration too the coding part can be rotated as desired with respect to the base body and, in this respect, there is no rotation of the two contact surfaces, which would affect the possible rotational angle positions of the two Components would restrict each other. If necessary, both components can even be profiled if this does not lead to a restriction of their rotational mobility relative to one another. For example, a radial, radial corrugation can be provided on one contact surface and a circular, concentric corrugation on the other contact surface, so that these two profiles running in different directions do not lead to a toothing of the coding part on the base body and accordingly the rotational mobility between these two components is not restricted. These profiles enlarge the surface of the respective contact surface and can therefore be advantageous for other reasons, as will be explained further below.

Bei dem gattungsgemäßen Verfahren zur Herstellung eines Schlüssels oder eines Schließstempels ist eine axiale Verschraubung des Kodierteils mit dem Grundkörper entlang deren gemeinsamer Mittellinie vorgesehen. Aufgrund der Profilierung der Kontaktflächen sind dort abweichende Drehwinkelstellungen ausgeschlossen, wenn das Kodierteil erst einmal am Grundkörper festgelegt ist, beispielsweise mittels der erwähnten Verschraubung.In the generic method for producing a key or a locking stamp, the coding part is axially screwed to the base body along their common center line. Due to the profiling of the contact surfaces, deviating angles of rotation are ruled out there once the coding part is fixed on the base body, for example by means of the screw connection mentioned.

Bei dem vorliegenden Vorschlag allerdings ist eine mechanische Festlegung der jeweiligen Drehwinkelstellung, die das Kodierteil gegenüber dem Grundkörper einnimmt, nicht vorgesehen. Das Kodierteil muss dennoch am Grundkörper in der gewählten Drehwinkelstellung so befestigt werden, dass die beiden Bauteile zugfest und drehfest miteinander verbunden sind, also gegen Kräfte gesichert sind, welche die beiden Bauteile gegeneinander zu verdrehen oder auseinanderzuziehen bestrebt sind. Beispielsweise können, nachdem das Kodierteil und der Grundkörper in ihrer gewünschten Drehwinkelstellung angeordnet worden sind, zwei parallele Gewindebohrungen in axialer Richtung erzeugt werden, um das Kodierteil mit dem Grundkörper drehfest und zugfest miteinander zu verschrauben. Oder es kann vorgesehen sein, dass sich die beiden Bauteile in axialer Richtung überlappen, so dass sie mittels einer radialen Bohrung, die durch beide Bauteile verläuft, miteinander verstiftet oder verschraubt werden können.In the present proposal, however, a mechanical definition of the respective angle of rotation position that the coding part assumes with respect to the base body is not provided. The coding part must nevertheless be attached to the base body in the selected angle of rotation position in such a way that the two components are connected to one another in a tensile and rotationally fixed manner, that is, secured against forces which tend to rotate the two components against each other or to pull them apart. For example, after the coding part and the base body have been arranged in their desired angle of rotation position, two parallel threaded bores can be produced in the axial direction in order to screw the coding part to the base body in a torque-proof and tensile manner. Or it can be provided that the two components overlap in the axial direction so that they can be pinned or screwed to one another by means of a radial bore that runs through both components.

Vorteilhaft kann jedoch vorgesehen sein, dass das Kodierteil am Grundkörper ohne eine derartige aufwändige mechanische Nachbearbeitung befestigt wird. Um eine zuverlässig zug- und drehfeste Befestigung des Kodierteils am Grundkörper sicherzustellen, kann daher statt einer mechanischen Befestigung des Kodierteils am Grundkörper vorgesehen sein, diese beiden Bauteile miteinander zu verkleben oder zu verschweißen, oder mittels einer Vergussmasse zu verbinden. Bei der Verklebung kann Klebstoff zwischen den beiden Kontaktflächen vorgesehen sein. Die weiter oben erläuterte Profilierung kann die Oberfläche der Kontaktflächen vergrößern und damit die Kraftübertragung von einem Bauteil auf den Klebstoff verbessern. Und die Vergussmasse kann ausgehärtet werden und anschließend - ggf. auch ohne eine Verklebungswirkung - einen Formschluss zwischen dem Kodierteil und dem Grundkörper bewirken, selbst wenn diese beiden Bauteile nicht unmittelbar aneinander formschlüssig anliegen, sondern lediglich jeweils eine Profilierung aufweisen, die nur mit der ausgehärteten Vergussmasse formschlüssig zusammenwirkt.However, it can advantageously be provided that the coding part on the base body without such a complex mechanical Post-processing is attached. In order to ensure that the coding part is reliably secured against tension and rotation on the base body, instead of mechanically fastening the coding part on the base body, provision can be made for these two components to be glued or welded to one another, or to be connected by means of a potting compound. When gluing, adhesive can be provided between the two contact surfaces. The profiling explained above can enlarge the surface of the contact surfaces and thus improve the force transmission from a component to the adhesive. And the potting compound can be cured and then - possibly even without an adhesive effect - bring about a form fit between the coding part and the base body, even if these two components do not lie directly against one another in a form-fitting manner, but only each have a profile that only works with the cured potting compound cooperates positively.

Durch das vorgeschlagene Verfahren können unter Verwendung desselben Kodierteils und desselben Grundkörpers unterschiedliche funktionsfähige Schließstempel bzw. Schlüssel in einer sehr großen Anzahl hergestellt werden, wobei sich diese Anzahl nach der Fertigungspräzision des Schlosses richtet: Wenn beispielsweise aufgrund einer besonders exakten Führung des Schlüssels bei seiner Annäherung an den Schließstempel sichergestellt ist, dass bereits ein Kodierteil des Schlüssels nicht mehr zum Kodierteil des Schließstempel passt, wenn das Kodierteil des Schlüssels eine Drehwinkelabweichung von einem Grad zum Kodierteil des Schließstempels aufweist, so können dementsprechend 360 unterschiedlich ausgestaltete Schlüssel bzw. Schließstempel unter Verwendung der gleichen Bauteile hergestellt werden, indem jeweils die Kodierteile um 1° hinsichtlich des Drehwinkels versetzt am Grundköper befestigt werden. Mit einer mechanischen Kodierung zwischen dem Kodierteil und dem Grundkörper sind deutlich geringere unterschiedliche Varianten des Schlüssels bzw. Schließstempels erzielbar, so dass dementsprechend das vorschlagsgemäße Verfahren eine erheblich wirtschaftlichere Fertigung des Schlüssels bzw. Schließstempels aufgrund der erheblich umfangreicheren Verwendungsmöglichkeit von Gleichteilen ermöglicht.With the proposed method, using the same coding part and the same base body, a very large number of different functional locking stamps or keys can be produced, this number depending on the manufacturing precision of the lock: If, for example, due to the particularly precise guidance of the key when it approaches The locking stamp ensures that a coding part of the key no longer fits the coding part of the locking stamp, if the coding part of the key has a rotational angle deviation of one degree from the coding part of the locking stamp, then accordingly 360 differently designed keys or locking stamps can be used using the same components can be produced by attaching the coding parts to the base body offset by 1 ° with regard to the angle of rotation. With a mechanical coding between the coding part and the base body, significantly fewer different variants of the key or locking stamp can be achieved, so that Accordingly, the proposed method enables a considerably more economical production of the key or locking stamp due to the considerably more extensive use of identical parts.

Vorteilhaft kann das Kodierteil lediglich an seinem äußeren Umfang am Grundkörper befestigt werden. Kodierteil und Grundkörper können also zunächst in der gewünschten Drehwinkelstellung zueinander geführt und aneinander gehalten werden und anschließend kann in besonders einfacher Weise von außen die entsprechende Befestigung des Kodierteils am Grundkörper bewirkt werden. Beispielsweise können die beiden Bauteile außen umlaufend eine Nut bilden, so dass die Nutränder von diesen beiden Bauteilen geschaffen werden und sodass in der Nut beispielsweise Klebstoff aufgenommen werden kann, mit dem dann die beiden Bauteile fest miteinander verbunden sind. Dadurch, dass der Klebstoff nicht flächig zwischen den beiden Bauteilen zugegeben wird, sondern lediglich außen am Rand, wird eine besonders präzise Ausrichtung des Kodierteils am Grundkörper unterstützt, indem nämlich das Kodierteil nicht auf einem Klebstofffilm aufschwimmen und sich ggf. in unerwünschter Weise verlagern kann, bevor der Klebstoff ausgehärtet ist. Wird jedoch eine zuverlässige Fixierung der beiden Bauteile zueinander sichergestellt, so kann auch abweichend vom äußeren Umfang die Zugabe von Klebstoff auf den Kontaktflächen von Kodierteil und Grundkörper vorgesehen sein, um auf diese Weise eine möglichst große Verklebungsfläche bereitzustellen und so eine mechanisch hochbelastbare Befestigung des Kodierteils am Grundkörper zu ermöglichen.The coding part can advantageously only be attached to the base body at its outer circumference. The coding part and the base body can thus initially be guided to one another in the desired angular position and held against one another, and then the corresponding fastening of the coding part on the base body can be effected from the outside in a particularly simple manner. For example, the two components can form a circumferential groove on the outside so that the groove edges are created by these two components and so that, for example, adhesive can be received in the groove, with which the two components are then firmly connected to one another. The fact that the adhesive is not added flat between the two components, but only on the outside of the edge, supports a particularly precise alignment of the coding part on the base body, in that the coding part cannot float on an adhesive film and possibly shift in an undesirable manner. before the adhesive has hardened. However, if a reliable fixation of the two components to one another is ensured, the addition of adhesive to the contact surfaces of the coding part and the base body can also be provided in a way deviating from the outer circumference, in order to provide the largest possible bonding surface and thus a mechanically highly resilient fastening of the coding part to the To enable basic body.

Wenn die Verbindung von Kodierteil und Grundkörper durch Verschweißung erfolgt, kann ebenfalls diese Befestigung auf den äußeren Umfang der beiden Bauteile beschränkt werden, denn die Verschweißung ermöglicht einerseits, auch wenn sie nur am Umfang erfolgt, eine mechanisch hochbelastbare Befestigung des Kodierteils am Grundkörper, und zum Zweiten können die beiden Bauteile möglichst einfach und wirtschaftlich ausgestaltet werden, beispielsweise als massive Blöcke bzw. Scheiben oder Zapfen, so dass die Kontaktflächen, wenn sie aneinander anliegen, ohnehin nur von außen zugänglich sind, insbesondere wenn diese Kontaktflächen beide glattflächig ausgestaltet sind und sich insofern keine Zwischenräume zwischen den beiden Bauteilen ergeben.If the connection of the coding part and the base body is made by welding, this fastening can also be limited to the outer circumference of the two components, because the welding enables on the one hand, even if it is only done on the circumference, a mechanically highly resilient fastening of the coding part on the base body, and for The second can Both components are designed as simply and economically as possible, for example as solid blocks or discs or pegs, so that the contact surfaces, when they are in contact with one another, are only accessible from the outside anyway, especially if these contact surfaces are both smooth-surfaced and there are no gaps between them the two components result.

Vorteilhaft kann die Verschweißung der beiden Kodierteile mittels einer Laserverschweißung durchgeführt werden. Durch die präzise zu setzenden Laserstrahlen mit sehr geringem Durchmesser sind beispielsweise auch Stellen an den beiden Kontaktflächen zugänglich, die vom äußeren Umfang beabstandet sind, wenn beispielsweise eine oder beide Kontaktflächen profiliert sind, so dass in diesem Fall nicht nur am äußeren Umfang, sondern auch weiter zum Mittelpunkt der Kontaktflächen hin Befestigungsstellen zwischen dem Kodierteil und dem Grundkörper geschaffen werden können. Wenn aber in wirtschaftlich vorteilhafter Ausgestaltung das Kodierteil und der Grundkörper jeweils glattflächige Kontaktflächen aufweisen und nur zirkumferent am äußeren Umfang eine Nahtlinie vorliegt, so ermöglicht die Laserverschweißung eine sehr präzise Schweißnaht, über welche die beiden benachbarten Bauteile kaum erwärmt werden und dementsprechend vor Verzug geschützt sind, so dass unerwünschte Verformungen zuverlässig ausgeschlossen werden können und die präzise Ausrichtung der Kodierflächen, die für das Zusammenwirken der beiden Kodierteile am Schlüssel einerseits und am Schließstempel andererseits wesentlich ist, zuverlässig gewährleistet werden kann. Die thermische Belastung durch die Verschweißung kann insbesondere vorteilhaft auch dadurch möglichst gering gehalten werden, dass die Verschweißung in Form einer Punktverschweißung mittels mehrerer einzelner Schweißpunkte erfolgt.The welding of the two coding parts can advantageously be carried out by means of laser welding. The laser beams with a very small diameter to be set precisely also make places accessible on the two contact surfaces that are spaced from the outer circumference, for example if one or both contact surfaces are profiled, so that in this case not only on the outer circumference, but also further fastening points can be created between the coding part and the base body towards the center of the contact surfaces. If, however, in an economically advantageous configuration, the coding part and the base body each have smooth-surfaced contact surfaces and a seam line is only present around the circumference on the outer circumference, then the laser welding enables a very precise weld seam, over which the two adjacent components are hardly heated and are accordingly protected from distortion. so that undesired deformations can be reliably excluded and the precise alignment of the coding surfaces, which is essential for the interaction of the two coding parts on the key on the one hand and on the locking die on the other hand, can be reliably guaranteed. The thermal load caused by the weld can also advantageously be kept as low as possible in that the weld takes place in the form of a spot weld by means of a plurality of individual weld points.

Die beiden Bauteile in Form des Grundkörpers und des Kodierteils können mittels einer einzigen Verbindungsart miteinander verbunden werden. Es kann jedoch vorgesehen sein, zwei oder mehrere Verbindungsarten zu kombinieren, beispielsweise die Bauteile sowohl miteinander zu verkleben als auch zusätzlich mittels einer Schweißnaht oder eines bzw. mehrerer Schweißpunkte. Die Verklebung ermöglicht eine Spaltabdichtung zwischen den beiden Bauteilen, und die Verschweißung kann als zusätzliche Sicherung die mechanische Belastung der Verklebung mindern. Oder bei einer mechanischen Verbindung durch Verschraubung oder Verstiftung kann zusätzlich eine Verklebung bzw. Verschweißung vorgesehen sein.The two components in the form of the base body and the coding part can be connected to one another by means of a single type of connection get connected. It can, however, be provided to combine two or more types of connection, for example both to glue the components together and additionally by means of a weld seam or one or more weld points. The bond enables a gap to be sealed between the two components, and the welding can, as an additional safeguard, reduce the mechanical stress on the bond. Or in the case of a mechanical connection by screwing or pinning, gluing or welding can also be provided.

Für die korrekte Positionierung des Kodierteils am Grundkörper kann vorteilhaft eine Zentrierhilfe vorgesehen sein, welche die Durchführung des vorgeschlagenen Verfahrens erleichtert. Vorteilhaft kann eine solche Zentrierhilfe in Form eines umlaufenden Kragens ausgestaltet sein, der an einem Bauteil, nämlich entweder am Kodierteil oder am Grundkörper, vorgesehen ist und das jeweils andere Bauteil zirkumferent übergreift, so dass das korrespondierende Bauteil in sämtlichen radialen Bewegungsrichtungen zuverlässig gegen Verschiebungen gesichert und somit zentriert ist.For the correct positioning of the coding part on the base body, a centering aid can advantageously be provided, which facilitates the implementation of the proposed method. Such a centering aid can advantageously be designed in the form of a circumferential collar, which is provided on a component, namely either on the coding part or on the base body, and overlaps the other component circumferentially, so that the corresponding component is reliably secured against displacement in all radial directions of movement and is thus centered.

Embodiments of the present invention are explained in more detail below with reference to the purely schematic representations. It shows:
Fig. 1
a perspective view of a first embodiment, with a partially shown base body and an associated coding part spaced therefrom,
Fig. 2
a longitudinal section through a second embodiment, wherein the coding part is attached to the base body, and
Fig. 3
a cross section through the second embodiment along the line 3-3 in Fig. 2 .

Die Zeichnungen zeigen einen Grundkörper 1, der rein beispielhaft als zylindrischer Zapfen ausgestaltet und nur teilweise dargestellt ist. Es kann sich dabei um den Grundkörper 1 entweder eines Schlüssels oder eines Schließstempels handeln.The drawings show a base body 1, which is designed purely by way of example as a cylindrical pin and is only partially shown. It can be the base body 1 either a key or a locking stamp.

Es ist vorgesehen, den Grundkörper 1 mit einem Kodierteil 2 zu verbinden. Das Kodierteil weist an seinem freien, vom Grundkörper 1 abgewandten Ende eine Kodierfläche 3 auf, die als gestufte Stirnfläche des Kodierteils 2 ausgestaltet ist und durch einen Z-förmig verlaufenden Trennschnitt erzeugt worden ist, bei dem gleichzeitig auch ein komplementäres zweites Kodierteil erzeugt worden ist, so dass eines der Kodierteile 2 dem Schlüssel und das andere der beiden Kodierteile 2 dem Schließstempel des Schlosses zugeordnet werden kann.Provision is made for the base body 1 to be connected to a coding part 2. At its free end facing away from the base body 1, the coding part has a coding surface 3, which is designed as a stepped end face of the coding part 2 and has been produced by a Z-shaped separating cut, in which a complementary second coding part has also been produced at the same time, so that one of the coding parts 2 can be assigned to the key and the other of the two coding parts 2 can be assigned to the locking stamp of the lock.

Das in Fig. 1 dargestellte Kodierteil 2 weist der Kodierfläche 3 gegenüberliegend eine Kontaktfläche 4 auf, die bei der Herstellung des Schlüssels bzw. Schließstempels an eine gegenüberliegende Kontaktfläche 4 des Grundkörpers 1 angelegt wird. Bei dem dargestellten Ausführungsbeispiel ist vorgesehen, dass beide Kontaktflächen 4 glatt ausgestaltet sind, so dass eine vollflächige Anlage der beiden Kontaktflächen 4 aneinander ermöglicht wird. Aufgrund ihrer glatten Oberflächen ermöglichen die aneinander anliegenden Kontaktflächen 4 das Kodierteil 2 beliebig um eine Mittelachse 5 zu drehen, die gestrichelt eingezeichnet ist und durch den Grundkörper 1 sowie das Kodierteil 2 verläuft, so dass durch diese Drehbeweglichkeit das Kodierteil 2 in beliebigen Drehstellungen an den Grundkörper 1 angelegt werden kann.This in Fig. 1 The coding part 2 shown has a contact surface 4 opposite the coding surface 3, which contact surface 4 is applied to an opposite contact surface 4 of the base body 1 during the manufacture of the key or locking stamp. In the exemplary embodiment shown, it is provided that both contact surfaces 4 are designed to be smooth, so that full-surface contact of the two contact surfaces 4 on one another is made possible. Due to their smooth surfaces, the abutting contact surfaces 4 allow the coding part 2 to be rotated as desired about a central axis 5, which is shown in dashed lines and runs through the base body 1 and the coding part 2, so that this rotational mobility allows the coding part 2 to be in any rotational position on the base body 1 can be created.

Das Kodierteil 2 weist einen umlaufenden Kragen 6 auf, der als Zentrierhilfe dient und dessen innerer Durchmesser dem äußeren Durchmesser des Grundkörpers 1 entspricht.The coding part 2 has a circumferential collar 6 which serves as a centering aid and whose inner diameter corresponds to the outer diameter of the base body 1.

Nachdem die beiden Bauteile aneinander angelegt worden sind, sich also die Kontaktflächen 4 des Grundkörpers 1 und des Kodierteils 2 berühren, werden die beiden aneinander anliegenden Bauteile in dieser Stellung fixiert und miteinander verbunden, indem sie entlang ihrem Umfang miteinander mittels eines Lasers verschweißt werden. Die Laserschweißnaht entsteht dabei zwischen dem Kragen 6 und dem Grundkörper 1.After the two components have been placed against one another, that is to say the contact surfaces 4 of the base body 1 and of the coding part 2, the two adjacent components are fixed in this position and connected to one another by being welded to one another along their circumference by means of a laser. The laser weld seam is created between the collar 6 and the base body 1.

Dadurch, dass der Kragen 6 um den gesamten Umfang des Kodierteils 2 verläuft und nicht nur in Form einzelner Zentrierfinger o. dgl. ausgestaltet ist, bewirkt die erzeugte Schweißnaht einen dichten Anschluss des Kodierteils 2 an den Grundkörper 1, so dass beispielsweise weder Feuchtigkeit noch Verschmutzungen zwischen die beiden Bauteile eindringen können und die Trennfuge, die sich zwischen dem Grundkörper 1 und dem Kodierteil 2 ergibt, auf ihrer vollen Länge geschlossen ist. Die Stabilität der Befestigung, mit welcher das Kodierteil 2 an dem Grundkörper 1 festgelegt worden ist, wird auf diese Weise maximiert.Because the collar 6 runs around the entire circumference of the coding part 2 and is not only designed in the form of individual centering fingers or the like, the weld seam produced creates a tight connection between the coding part 2 and the base body 1, so that, for example, neither moisture nor dirt can penetrate between the two components and the parting line that results between the base body 1 and the coding part 2 is closed over its full length. The stability of the fastening with which the coding part 2 has been fixed to the base body 1 is maximized in this way.

Fig. 2 zeigt ein zweites Ausführungsbeispiel. Der Kragen 6, mittels welchem sich das Kodierteil 2 und der Grundkörper 1 überlappen, ist an dem Kodierteil 2 außen bündig vorgesehen und verläuft im Abstand von dem Grundkörper 1, hat also keine Führungs- oder Zentrierfunktion. Um dennoch das Kodierteil 2 präzise zu dem Grundkörper 1 auszurichten, ist eine Zentrierhilfe vorgesehen. Die Zentrierhilfe ist an der Kontaktfläche 4 des Grundkörpers 1 als kreisrunder Zapfen 7 und an der Kontaktfläche 4 des Kodierteils 2 als kreisrunde Bohrung 8 ausgestaltet, die den Zapfen 7 in radialer Richtung führt, aber beliebige Drehwinkelstellungen dieser beiden Bauteile zueinander ermöglicht. Fig. 2 shows a second embodiment. The collar 6, by means of which the coding part 2 and the base body 1 overlap, is provided flush on the outside of the coding part 2 and extends at a distance from the base body 1, so has no guiding or centering function. In order to align the coding part 2 precisely with the base body 1, a centering aid is provided. The centering aid is designed as a circular pin 7 on the contact surface 4 of the base body 1 and as a circular bore 8 on the contact surface 4 of the coding part 2, which guides the pin 7 in the radial direction, but allows these two components to be in any desired angle of rotation.

Das Kodierteil 2 weist in der inneren, zum Grundkörper 1 gerichteten Oberfläche seines Kragens 6 eine umlaufende erste Ringnut 9 auf, und der Grundkörper 1 weist in dem Bereich, in dem er in den Kragen 6 eintaucht, eine außen umlaufende, zweite Ringnut 10 auf. Die Ringnuten 9 und 10 stehen lediglich beispielhaft für Profilierungen, die in Richtung der Mittelachse 5 Vorsprünge bzw. Hinterschneidungen schaffen.The coding part 2 has a circumferential first annular groove 9 in the inner surface of its collar 6 directed towards the base body 1, and the base body 1 has an externally circumferential, second annular groove 10 in the area in which it dips into the collar 6. The annular grooves 9 and 10 are only examples of profiles that create projections or undercuts in the direction of the central axis 5.

Eine Vergussmasse 11 ist in den Spalt zwischen dem Grundkörper 1 und dem Kodierteil 2 eingefüllt worden und füllt auch die Ringnuten 9 und 10 aus. Sie stellt nach ihrer Aushärtung sicher, dass das Kodierteil 2 und der Grundkörper 1 zugfest miteinander verbunden sind, also nicht in axialer Richtung der Mittelachse 5 auseinandergezogen werden können. Obwohl das Kodierteil 2 und der Grundkörper 1 keinen Formschluss unmittelbar miteinander aufweisen, der sie zugfest miteinander verbinden würde, schafft die Vergussmasse mittelbar einen solchen Formschluss, selbst wenn sie nicht als Klebstoff kraftschlüssig an das Kodierteil 2 oder an den Grundkörper 1 anschließt. Die Vergussmasse weist daher vorzugsweise eine hohe mechanische Stabilität hinsichtlich ihrer Belastbarkeit durch Zug- und Scherkräfte auf und kann beispielsweise aus einem entsprechenden Kunststoff bestehen oder aus einem Material, welches als so genanntes Kaltmetall, Flüssigmetall oder Metall aus der Tube handelsüblich ist.A potting compound 11 has been poured into the gap between the base body 1 and the coding part 2 and also fills the annular grooves 9 and 10. After it has hardened, it ensures that the coding part 2 and the base body 1 are connected to one another in a tensile manner, that is to say cannot be pulled apart in the axial direction of the central axis 5. Although the coding part 2 and the base body 1 do not have a form fit that would connect them to one another with tensile strength, the potting compound indirectly creates such a form fit, even if it does not adjoin the coding part 2 or the base body 1 in a force-locking manner as an adhesive. The potting compound therefore preferably has a high mechanical stability with regard to its resilience to tensile and shear forces and can for example consist of a corresponding plastic or of a material which is commercially available as so-called cold metal, liquid metal or metal from the tube.

Während Fig. 2 eine Profilierung in axialer Richtung zeigt, nämlich durch die umlaufenden Ringnuten 9 und 10, zeigt Fig. 3 eine Profilierung des Grundkörpers 1 und des Kodierteils 2 in Drehrichtung, nämlich durch axial verlaufende erste Vorsprünge 12 am Grundkörper 1 und ebenfalls axial verlaufende zweite Vorsprünge 14 am Kodierteil 2. Nach Aushärten der Vergussmasse 11 sind der Grundkörper 1 und das Kodierteil 2 formschlüssig drehfest miteinander verbunden, wobei auch in dieser Hinsicht das Kodierteil 2 und der Grundkörper 1 keinen Formschluss unmittelbar miteinander aufweisen, sondern dieser Formschluss mittelbar geschaffen ist, nämlich durch die Vergussmasse.While Fig. 2 shows a profile in the axial direction, namely by the circumferential annular grooves 9 and 10 shows Fig. 3 a profiling of the base body 1 and the coding part 2 in the direction of rotation, namely by axially extending first projections 12 on the base body 1 and also axially extending second projections 14 on the coding part 2. After the casting compound 11 has hardened, the base body 1 and the coding part 2 are positively rotatably connected to each other In this regard, too, the coding part 2 and the base body 1 do not have a form fit directly with one another, but this form fit is created indirectly, namely by the potting compound.
