Abstract

The aim of the invention is to improve locking devices, especially for use in motor vehicles, in which a locking cylinder is mounted on at least one door and this locking cylinder is operated by a key (10) which has code tracks (13) on the flat sides (11) thereof. To this end, the profile (14) which typifies the key (10) and which, according to the state of the art, is arranged in the outer areas of the flat sides (11) of the key (10) is realized in the form of a groove (14) that is located on the narrow sides (12) of the key (10) and recessed therein. In addition, a projection is provided on the upper and/or lower narrow side of the key channel of the locking cylinder and, when the key (10) is inserted, the projection engages inside the groove (14') located on the key. The inventive measures permit the height of the key (10) to be reduced since the edges of the flat sides (11) of the key (10) can be brought close to the code path (13). In addition, the key (10) wobbles less by virtue of the fact that the projection is guided in the groove (14') when the key is inserted into the locking cylinder.

Description

Schließvorrichtung, insbesondere für Kraftfahrzeuge Locking device, in particular for motor vehicles

Die Erfindung richtet sich auf eine Schließvorrichtung der im Oberbegriff des Anspruches 1 genannten Art. Das Anwendungsgebiet der Erfindung richtet sich insbesondere auf Kraftfahrzeuge etc..The invention is directed to a locking device of the type mentioned in the preamble of claim 1. The field of application of the invention is particularly directed to motor vehicles, etc.

Bei Schließvorrichtungen der oben genannten Art ist es bei einem von der Fa. Huf gefertigten Schlüssel bekannt, Codebahnen auf beiden Flächenseiten des Schlüssels rotationssymmetrisch zur Längsachse des Schlüssels anzuordnen. Auf jeder der beiden Flächenseiten ist jeweils im Bereich einer Kante ein, den Schlüssel typisierendes Profil angebracht. Diese Profile auf beiden Flächeseiten des Schlüssels sind ebenfalls rotationssymmetrisch zueinander angeordnet. Durch die rotationssymmetrische Anordnung der Codebahnen und Profile kann der Schlüssel in beiden möglichen Einstecklagen in den Schlüsselkanal eines Schließzylinders eingeführt werden.In the case of locking devices of the type mentioned above, in the case of a key manufactured by Huf, it is known to arrange code tracks on both surface sides of the key in a rotationally symmetrical manner with respect to the longitudinal axis of the key. On each of the two surface sides there is a profile typing the key in the area of an edge. These profiles on both surface sides of the key are also arranged rotationally symmetrically to one another. Due to the rotationally symmetrical arrangement of the code tracks and profiles, the key can be inserted into the key channel of a locking cylinder in both possible insertion positions.

Der Schließ zylinder ist vorzugsweise an einer Tür oder Klappe eines Fahrzeugs angeordnet und bewirkt mittels einer Betätigung des in den Schlüsselkanal eingesteckten Schlüssels die Ner- oder Entriegelung einer Betätigungseinrichtung zum Offen eines Schlosses oder das Betätigen eines Schalters.The lock cylinder is preferably arranged on a door or flap of a vehicle and, by actuating the key inserted into the key channel, causes the locking or unlocking of an actuating device to open a lock or the actuation of a switch.

Damit nicht jeder Schlüssel in jeden Schließzylinder einführbar ist, sind wie bereits im Vorhergehenden ausgeführt, Profile an den äußeren Bereichen der Flächenseiten vorgesehen. Die Profile der Schlüssel zu unterschiedlichen Typen von Schließzylindern sind dabei unterschiedlich ausgeformt und dimensioniert, und korrespondieren jeweils mit entsprechend ausgeformten Stegen/Vorsprüngen an den Seitenwänden des Schlüsselkanals.So that not every key can be inserted into each locking cylinder, profiles are provided on the outer areas of the flat sides, as already explained above. The profiles of the keys to different types of locking cylinders are shaped and dimensioned differently, and correspond to correspondingly shaped webs / projections on the side walls of the key channel.

Die Codebahn benötigt aus fertigungstechnischen Gründen eine bestimmte Mindesthöhe, die auch ein reibungsloses, nicht hakendes Durchfahren der Zuhaltungen in der Codebahn gewährleisten, wenn der Schlüssel in den Schlüsselkanal eingeführt wird.For technical reasons, the code track requires a certain minimum height, which also ensures that the tumblers in the code track can be passed smoothly, without being caught, when the key is inserted into the key channel.

Von Nachteil bei derartigen Schließvorrichtungen ist es, daß die Aufbruchresistenz dieser Schlößer nicht weiter durch eine Verkleinerung des Schlüsselkanals reduziert werden kann, da die minimale Bauhöhe der dazugehörigen Schlüssel durch die technisch bedingte Höhe der Codebahnen und die Profile begrenzt ist.A disadvantage of locking devices of this type is that the resistance to opening of these locks cannot be reduced further by reducing the size of the key channel, since the minimum height of the associated keys is limited by the technical height of the code tracks and the profiles.

Eine Verkleinerung der Schlüsselhöhe bei den bekannten Schlüsseln würde dazu führen, daß die außen an den Flächenseiten des Schlüssels angeordneten Profile die Codebahnen schneiden und diese öffnen würden. Der Schlüssel wäre dann nicht mehr funktionsfähig.A reduction in the key height in the known keys would lead to the profiles arranged on the outside of the flat sides of the key cutting the code paths and opening them. The key would then no longer be functional.

Aufgabe der Erfindung ist es eine Schließ Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, die die genannten Nachteile vermeidet. Dies wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 genannten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The object of the invention is to develop a locking device of the type mentioned in the preamble of claim 1, which avoids the disadvantages mentioned. This is achieved according to the invention by the measures mentioned in the characterizing part of claim 1, which have the following special meaning.

Gemäß Patentanspruch 1 genügt es, die zur Unterscheidung verschiedener Schlüsseltypen dienenden Profile an wenigstens einer der Schmalseiten in Form einer Nut anzuordnen. Durch diese Maßnahme, kann die Schlüsselhöhe weiter reduziert werden, da die Codebahnen nicht mehr durch die Profile aufgeschnitten werden können. Durch die resultierende mögliche Verkleinerung des Schlüsselkanals, wird der Schließzylinder auch aufbruchssicherer, da mit jedem mm den das Aufbruchswerkzeug kleiner werden muss, um noch in den Schlüsselkanal eingeführt zu werden, auch die maximal ausübbare Kraft kleiner wird.According to claim 1, it is sufficient to arrange the profiles used to distinguish different key types on at least one of the narrow sides in the form of a groove. With this measure, the key height can be reduced further, since the code tracks can no longer be cut through the profiles. As a result of the possible reduction in size of the key channel, the locking cylinder is also tamper-proof because with every mm Since the opening tool has to be smaller in order to be introduced into the key channel, the maximum force that can be exerted also becomes smaller.

Weiterhin ergibt sich bei der Anordnung einer Nut auf einer oder beider Schmalseiten des Schlüssels die überraschende Wirkung, dass der erfindungsgemäße Schlüssel das Kippeln verringert, und so ein weitaus geringerer Verschleiss des Schließzylinders und der Zuhaltungen bei wiederholtem Einführen und Betätigen des Schließzylinders mit dem Schlüssel erfolgt.Furthermore, with the arrangement of a groove on one or both narrow sides of the key, there is the surprising effect that the key according to the invention reduces the tilting, and thus there is much less wear on the locking cylinder and the tumblers when the locking cylinder is repeatedly inserted and actuated with the key.

Gemäß Anspruch 2 handelt es sich bei der, den Schlüssel typisierenden Nut um eine zu drei Längsseiten hin geschlossenen Nut, die zum Schlüsselinneren und zu den beiden Flächenseiten des Schlüssels hin abgeschlossen ist.According to claim 2, the key-typing groove is a closed to three long sides towards the groove, which is closed to the inside of the key and to the two surface sides of the key.

Werden, wie in Anspruch 3 vorgesehen, die Nuten auf jeweils beiden sich gegenüberliegenden Schmalflächen des Schlüssels angeordnet, so kann dieser Schlüssel auch in jeder möglichen Einstecklage in den Schlüsselkanal eingeführt werden. Es handelt sich dann um einen Wendeschlüssel.If, as provided in claim 3, the grooves are arranged on two opposing narrow surfaces of the key, this key can also be inserted into the key channel in any possible insertion position. It is then a reversible key.

Gemäß Anspruch 4 ist es ferner sinnvoll, dass in entsprechender Lage im Schlüsselkanal ein Vorsprung / Steg angeordnet ist, die in die Nut / Nuten des Schlüssels eingreifen, wenn dieser in den Schlüsselkanal eingesteckt wird.According to claim 4, it is also useful that a projection / web is arranged in a corresponding position in the key channel, which protrude into the groove / grooves of the key when it is inserted into the key channel.

Nach Anspruch 5 kann es auch sinnvoll sein, wenn die am Schlüssel angeordnete Nut eine Anschlagfläche an ihrem kopfseitigen Ende aufweist und diese Anschlagfläche gegen eine am Vorsprung angeordnete Kopffläche aufläuft, wodurch die Einstecktiefe des Schlüssels begrenzt wird.According to claim 5, it can also be useful if the groove arranged on the key has a stop surface at its head end and this stop surface runs up against a head surface arranged on the projection, thereby limiting the insertion depth of the key.

Durch das gemäß Anspruch 7 vorgesehene mehrflächige Relief der Nut, das für jeden Schlüsseltyp variiert werden kann, insbesondere was die Anzahl der Flächen sowie deren Winkel zueinander als wie auch die Form der Flächen betrifft, kann eine große Vielfalt von Schlüsseltypen erzeugt werden.Due to the multi-surface relief of the groove provided according to claim 7, which can be varied for each key type, in particular what the number of surfaces As well as their angle to each other and the shape of the surfaces, a wide variety of key types can be generated.

Diese Vielfalt wird durch die Kombination von radieilen Flächenabschnitten und ebenen Flächenabschnitten in der Nutfläche noch erhöht.This variety is further increased by the combination of radial surface sections and flat surface sections in the groove surface.

Gemäß Anspruch 9 ist es sinnvoll, wenn der, in die Nut einfahrende Vorsprung / Steg entsprechende Seitenflächen aufweist, die wenigstens zu einem Teil der korrespondierenden schlusselseitigen Flächenabschnitte in der Nut formschlüssig sind.According to claim 9, it makes sense if the projection / web which moves into the groove has corresponding side surfaces which are at least partially form-fitting in the groove on the corresponding key-side surface sections.

Anhand der verschiedenen Reliefs der Nut bzw. der korrespondierenden Reliefs der Vorsprünge im Schlüsselkanal kann innerhalb eines Schließsystems an einem Hauptschlüssel eine Vielzahl von Nebenschlüsseln zugeordnet werden.On the basis of the different reliefs of the groove or the corresponding reliefs of the protrusions in the key channel, a large number of secondary keys can be assigned to a master key within a locking system.

Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgender Beschreibung und den Zeichnungen. In den Zeichnungen ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigen:Further measures and advantages of the invention result from the subclaims, the following description and the drawings. In the drawings, the invention is shown in one embodiment. Show it:

Die erfindungsgemäße Schließ Vorrichtung richtet sich insbesondere auf Schließzylinder für Innenbahn- oder Bohrmuldenschlüssel. 'The locking device according to the invention is aimed in particular at locking cylinders for inner track or dimple keys. '

Die erfmdungsgemäße Schließvorrichtung umfasst einen Schließ zylinder 20, dessen in einem Zylindergehäuse (hier nicht zeichnerisch dargestellt) drehbarer Zylinderkern (hier nicht zeichnerisch dargestellt) durch zahlreiche federbelastete Zuhaltungen 27 normalerweise gesperrt ist. Im vorliegenden Fall handelt es sich um Plättchenzuhaltungen. Diese Zuhaltungen 27 werden beim Einführen eines ordnungsgemäßen Schlüssels 10, der an seinen Flächenseiten 1 1 die Codebahnen 13 aufweist, derart verstellt, dass die Zuhaltungen nicht mehr über die Mantelfläche des Zylinderkerns hinausragen, und der Zylinderkern somit im Zylindergehäuse drehbar ist. Durch eine Drehbewegung des eingesteckten Schlüssels 10 kann der Benutzer daraufhin eine Betätigungseinrichtung mittels der Schließvorrichtung entriegeln oder verriegeln, je nach Drehrichtung des Schlüssels 10.The locking device according to the invention comprises a locking cylinder 20, the rotatable cylinder core (not shown in the drawing) in a cylinder housing (not shown in the drawing) which is normally blocked by numerous spring-loaded tumblers 27. In the present case, they are plate tumblers. These tumblers 27 are adjusted when inserting a proper key 10, which has the code tracks 13 on its flat sides 11, such that the tumblers no longer protrude beyond the circumferential surface of the cylinder core, and the cylinder core is thus rotatable in the cylinder housing. By rotating the inserted key 10, the user can then unlock or lock an actuating device by means of the locking device, depending on the direction of rotation of the key 10.

Beim Einschieben des Schlüssels 10 in den Schlüsselkanal 21 eines Schließzylinders 20, wie er in Fig. 5 schematisch dargestellt ist, durchfahren die im Schlüsselkanal 21 angeordneten Zuhaltungen 27 die in diesem Ausführungsbeispiel auf beiden Flächenseiten 1 1 des Schlüssels 10 angeordneten Codebahnen 13. Die Zuhaltungen 27 bewegen sich beim Einfahren des Schlüssels 10 in den Schließzylinder 20 entsprechend der Topographie der Führungsflächen 16, die entlang der Codebahnen 13 angeordnet sind. In der Endposition des Schlüssels 10 sind die Zuhaltungen in ihrer, dem Zylinderkern des Schließzylinders eine Drehbewegung erlaubenden Stellung. Bei dem erfindungsgemäßen Schlüssel 10, wie er in den Fig. 1 bis 3 dargestellt ist, ist eine Nut 14', 14" auf beiden Schmalseiten 12 des Schlüssels 10 angeordnet. Diese Nut 14', 14" weist ein Relief 17 auf, das aus einer Aneinanderreihung verschiedener Flächenabschnitte 18, 19 besteht. Durch diese Aneinanderreihung verschiedener Flächenabschnitte 18, 19 können viele verschiedene Nuttypen erzeugt werden, so dass nicht jeder Schlüssel 10 in jeden 'Schließzylinder 20 der vorgesehenen Bauart einführbar ist.When the key 10 is inserted into the key channel 21 of a locking cylinder 20, as is shown schematically in FIG. 5, the tumblers 27 arranged in the key channel 21 pass through the code tracks 13 arranged in this exemplary embodiment on both surface sides 11 of the key 10. The tumblers 27 move when the key 10 is inserted into the locking cylinder 20 in accordance with the topography of the guide surfaces 16 which are arranged along the code tracks 13. In the end position of the key 10, the tumblers are in their position allowing the cylinder core of the lock cylinder to rotate. In the key 10 according to the invention, as shown in FIGS. 1 to 3, a groove 14 ', 14 "is arranged on both narrow sides 12 of the key 10. This groove 14', 14" has a relief 17 which consists of there is a series of different surface sections 18, 19. By lining up different surface sections 18, 19, many different types of grooves can be created, so that not every key 10 can be inserted into each lock cylinder 20 of the type provided.

Im Ausführungsbeispiel eines Hauptschlüssels eines Schließsystems, wie in Fig. 2 dargestellt, sind Zylinder-Flächenabschnitte 18 neben planaren Flächenabschnitten 19 angeordnet, die das Relief 17 der Nut 14' bilden. Bei dem in Fig. 3 im Schnitt dargestellten Nebenschlüssel 10', zu dem selben Schließsystem, zu dem auch der in Fig. 2 dargestellte Hauptschlüssel 10 gehört, sind lediglich planare Flächenabschnitte 19 im Relief der Nut 14" angeordnet. Der Nebenschlüssel 10' gemäß Fig. 3 kann nicht in einen Haupt- Schließzylinder eingesteckt werden, der alleine dem in Fig. 2 dargestellten Hauptschlüssel 10 zugeordnet ist. Andersrum kann jedoch der Hauptschlüssel 10 auch in einen Schließzylinder eingesteckt werden und diesen betätigen, der einen Nebenschlüssel 10' zugeordnet ist.In the exemplary embodiment of a master key of a locking system, as shown in FIG. 2, cylinder surface sections 18 are arranged next to planar surface sections 19, which form the relief 17 of the groove 14 '. 3, to the same locking system to which the master key 10 shown in FIG. 2 also belongs, only planar surface sections 19 are arranged in the relief of the groove 14 ". The secondary key 10 'according to FIG 3 cannot be inserted into a master lock cylinder which is solely assigned to the master key 10 shown in Fig. 2. Conversely, however, the master key 10 can also be inserted into a lock cylinder and actuate this, which is associated with a secondary key 10 '.

Als Gegenstück zu den schlusselseitigen Nuten sind an den Schmalseiten 22 des Schlüsselkanals 21 des Schließzylinders 20 Vorsprünge 24 angeordnet (vergl. Fig. 5), die parallel zum Längsverlauf des Schlüsselkanals 22 angeordnet sind.As a counterpart to the key-side grooves 20 projections 24 are arranged on the narrow sides 22 of the key channel 21 of the locking cylinder (see FIG. 5), which are arranged parallel to the longitudinal course of the key channel 22.

Die im Schlüsselkanal 21 angeordneten Vorsprünge 24 weisen an ihrer Oberfläche angeordnete parallel zu ihrer Längsachse verlaufende Mantelflächen 26 auf. Das äußere Relief des Vorsprungs 26 stellt dabei ein negatives Abbild des nutseitigen Reliefs 17 des zu diesem Schließzylinder 20 passenden Schlüssels 10 dar. Beim Einschieben des Schlüssels 10 in den Schlüsselkanal 21 passen somit die vorgesehenen Vorsprünge 24 formschlüssig in die Nuten 14'. Hierbei ist allerdings zu bemerken, dass beim Einstecken eines Hauptschlüssel in den Schlüsselkanal eines Neben-Schließzylinders mit einem nebengeordneten Vorsprungsprofil nur ein teilweiser Formschluss zwischen den Nuten und den jeweiligen Vorsprüngen vorliegt. So ist der Hauptschlüssel 10 gemäß Fig. 2 in einen Schließ zylinder einsteckbar, der ein Vorsprungsrelief gemäß einer negativen Ausformung der Nut 14" aus Fig. 3 aufweist.The projections 24 arranged in the key channel 21 have on their surface arranged lateral surfaces 26 running parallel to their longitudinal axis. The outer relief of the projection 26 represents a negative image of the nut-side relief 17 of the key 10 matching this lock cylinder 20. When the key 10 is inserted into the key channel 21, the projections 24 provided fit into the grooves 14 'in a form-fitting manner. It should be noted here, however, that when a master key is inserted into the key channel of a secondary locking cylinder with a secondary projection profile, there is only a partial positive connection between the grooves and the respective projections. The master key 10 according to FIG. 2 can be inserted into a locking cylinder which has a projection relief in accordance with a negative shape of the groove 14 "from FIG. 3.

In Fig. 4 ist ferner ein Schnitt durch einen Schlüssel 10" gemäß dem Stand der Technik dargestellt, der jedoch in seiner Höhe verkleinert wurde, wobei das den Schlüssel typisierende Profil 14 in unveränderter Tiefe angebracht worden ist. Dieses Profil 14 öffnet hierbei jeweils die Codebahn 13 an den Stellen, an denen die Codebahn 13 sich dem Ende der Flächenseite 1 1 annähert. Begrenzt man die maximale Höhe solcher Spitzen der Codebahn 13, so würde gleichzeitig auch die Anzahl der Variationsmöglichkeiten der Codebahnen 13 erheblich geringer. Es könnten viel weniger Schlüssel mit verschiedenen Codebahnen 13 aufgelegt werden. Derselbe Nachteil ergibt sich auch aus einer Verkleinerung des Profils 14 wenn dieses auf eine bestimmte Eintiefung begrenzt wird. Auch hierdurch wird die Variation in den Schlüsseltypen erheblich eingeschränkt. FIG. 4 also shows a section through a key 10 "according to the prior art, which, however, has been reduced in height, the profile 14 typing the key being attached in unchanged depth. This profile 14 opens the code path in each case 13 at the points at which the code path 13 approaches the end of the surface side 1 1. If the maximum height of such peaks of the code path 13 is limited, the number of possible variations of the code paths 13 would also be considerably lower at the same time different code paths 13. The same disadvantage also results from a downsizing of the profile 14 if this is limited to a certain recess, which also considerably limits the variation in the key types.
