Abstract

The invention relates to a lock/key configuration, in which the flat key has, starting from each wide side (2) in the region of the key spine, a rib (3) which forms with the wide sides (2) of the flat key (1) an angle different from 90@. Provided on the side faces of the ribs (3) are profile variations which cooperate with corresponding longitudinal grooves and longitudinal ribs in the side walls of the keyway. The invention relates, furthermore, to a method for producing a cylinder plug for lock/key configurations of this type. <IMAGE>

Description

Die Erfindung betrifft eine Schloß-Schlüsselausbildung mit den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a lock key training with the features in the preamble of claim 1.

Allgemein bekannt sind sogenannte Kreuzbartschlüssel, bei denen die Längskanten der einzelnen Bärte durch Zuhaltungen abgeastet werden. Als Beispiel hierfür kann die CH 162 691 genannt werden. Bei diesen Kreuzbartschlüsseln betragt der Winkel zwischen den einzelnen Bärten 90°, d.h. sie sind im rechten Winkel zueinander angeordnet.So-called crossbar keys are generally known, in which the longitudinal edges of the individual beards are scuffed off using tumblers. CH 162 691 can be cited as an example of this. With these cross bit keys the angle between the individual beards is 90 ° , ie they are arranged at right angles to each other.

Es ist aber auch ein Schlüssel mit zugehörigem Zylinderkern bekanbnt, bei dem die Bärte unter von 90 verschiedenen Winkeln, z.B. strahlenförmig, angeordnet sind (DE 680 416). Gemeinsam ist ist diesen Lösungen aber, daß Jeweils die Längskanten der Bärte abgetastet werden.But there is also a key with associated cylinder core, in which the beards are at 90 different angles, e.g. radiating, are arranged (DE 680 416). What these solutions have in common, however, is that the longitudinal edges of the beards are scanned.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Flachschlüssel eine Ausbildung vorzuschlagen, die sich durch eine große Zahl von Profilvariationsmöglichkeiten auszeichnet, und die damit als Anlagenprofil eingesetzt werden kann.The invention has for its object to propose a training with a flat key, which is characterized by a large number of profile variation options, and which can thus be used as a system profile.

Gelöst wird diese Aufgabe mit den Merkmalen im Kennzeichen des Anspruchs 1.This problem is solved with the features in the characterizing part of claim 1.

Der wesentliche Gedanke der Erfindung ist darin zu sehen, daß hier, abweichend von den üblichen Flachschlüsseln, die lediglich an den Breitseiten Profilvariationen aufweisen, noch zusätzliche Rippen vorgesehen werden, die aber nicht wie bei Kreuzbartschlüsseln üblich, im Bereich der Längskanten abgetastet werden, sondern diese Rippen weisen an ihren Seitenflächen Profilvariationen auf, die mit entsprechenden Kerben bzw. Nuten im Zylinderkern zusammenwirken. Diese Rippen können unter gleichem oder unterschiedlichem Winkel zum Flachschlüssel selbst angeordnet sein. Durch die Möglichkeiten der Profilvariationen an den Seitenflächen und die unterschiedlichen Winkelanordnungen lassen sich die Variationsmöglichkeitenen erheblich steigern.The main idea of the invention is to be seen in the fact that, in contrast to the usual flat keys, which only have profile variations on the broad sides, additional ribs are provided, which, however, are not scanned in the region of the longitudinal edges, as is customary with cross bit keys, but rather these Ribs have profile variations on their side surfaces, which interact with corresponding notches or grooves in the cylinder core. These ribs can be arranged at the same or different angles to the flat key itself. Due to the possibilities of profile variations on the side surfaces and the different angular arrangements, the possible variations can be increased considerably.

Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer derartigen Schloßausbildung, und zwar insbesondere des Zylinderkernes. Dieser Zylinderkern besteht gemäß der Erfindung aus einer Hülse, die im oberen Bereich, entsprechend den Profilvariationen an den oberen Seitenwänden der Rippen, Längsnuten bzw. -rippen aufweist, sowie einem in diese Hülse eingesetzten Zylinderkernteil, das mit den Längsnuten bzw. Längsrippen versehen ist, die den Profilvariationen an den Unterseiten der Rippen entsprechen. Auf diese Weise läßt sich der Zylinderkern in einfacher Weise herstellen und nach Zusammenbau und Verbindung der Zylinderkernhülse mit dem eingelegten Zylinderkernteil steht der Schlüsselkanal entsprechend den vorgegebenen Profilvariationen zur Verfügung.The invention further relates to a method for producing such a lock design, in particular the cylinder core. According to the invention, this cylinder core consists of a sleeve which has longitudinal grooves or ribs in the upper region, corresponding to the profile variations on the upper side walls of the ribs, and a cylinder core part which is inserted into this sleeve and is provided with the longitudinal grooves or longitudinal ribs, which correspond to the profile variations on the undersides of the ribs. In this way, the cylinder core can be manufactured in a simple manner, and after assembly and connection of the cylinder core sleeve to the inserted cylinder core part, the key channel is available in accordance with the predetermined profile variations.

Die Erfindung soll nachfolgend anhand der Zeichnung erläutert werden, wobei diese einen vereinfachten Querschnitt durch den Zylinderkern mit dem Schlüsselkanal und eingeführtem Schlüssel darstellt. Die Profilausbildung soll hierbei anhand des Schlüssels erläutert werden, wobei es klar ist, daß der Schlüsselkanal entsprechend ausgebildet ist.The invention will be explained below with reference to the drawing, which represents a simplified cross section through the cylinder core with the key channel and inserted key. The profile formation is to be explained using the key, it being clear that the key channel is designed accordingly.

Der Schlüssel ist als Flachschlüssel 1 ausgebildet, und wie üblich sind hier an der Schlüsselbrust Kerben vorgesehen, die mit entsprechenden Kernstiften der Stiftzuhaltung zusammenwirken. Dies ist in der Figur nicht dargestellt, aber allgemein verständlich. Am Schlüsselrücken sind erfindungsgemäß nun beidseitig Rippen angesetzt, die im dargestellten Beispiel einen unterschiedlichen Winkel mit den Breitseiten des Flachschlüssels bilden. Diese Rippen 3 weisen auf der Oberseite bzw. Unterseite Profilvariationen 4 auf, denen entsprechende Längsrippen und Längsnuten im Schlüsselkanal zugeordnet sind. Die Zeichnung läßt erkennen, daß hier zahlreiche zusätzliche Profilvariationen möglich sind. Ebenfalls aus der Zeichnung ersichtlich ist der zweiteilige Aufbau des Zylinderkernes, nämlich aus einer Zylinderkerhülse 5 und einem Zylinderkereinsatz 6.The key is designed as a flat key 1, and as usual, notches are provided on the key face that interact with corresponding core pins of the pin tumbler. This is not shown in the figure, but is generally understandable. According to the invention, ribs are now attached to both sides of the key, which in the example shown form a different angle with the broad sides of the flat key. These ribs 3 have profile variations 4 on the top or bottom, to which corresponding longitudinal ribs and longitudinal grooves in the key channel are assigned. The drawing shows that numerous additional profile variations are possible here. Also apparent from the drawing is the two-part structure of the cylinder core, namely a cylinder core sleeve 5 and a cylinder core insert 6.

Bei der Herstellung dieses zusammengesetzten Zylinderkernes wird so verfahren, daß zunächst die Hülse bearbeitet wird, wobei diese im oberen Bereich nach der Bearbeitung Längsnuten und Längsrippen entsprechend der Profilvariation an der Oberseite der Rippen des Schlüssels aufweist.In the manufacture of this composite cylinder core, the procedure is such that the sleeve is first machined, with this having longitudinal grooves and longitudinal ribs in the upper region after the machining in accordance with the profile variation on the top of the ribs of the key.

Diese Profilvariationen sind in der Figur mit 5-10 bezeichnet. Unabhängig davon wird der Zylinderkerneinsatz hergestellt, und hierbei werden beim Fräsen Längsnuten und Längsrippen hergestellt, die mit den Profilvariationen übereinstimmen, die sich an der Unterseite der Rippen des Schlüssels befinden. Nach dieser getrennten Herstellung der Zylinderkernhülse und des Zylinderkerneinsatzes werden beide ineinander gesetzt und miteinander verbunden, so daß auf diese Weise der fertige Schlüsselkanal entsteht.These profile variations are designated 5-10 in the figure. Regardless of this, the cylinder core insert is produced, and in this process, longitudinal grooves and longitudinal ribs are produced which correspond to the profile variations which are located on the underside of the ribs of the key. After this separate production of the cylinder core sleeve and the cylinder core insert, both are placed one inside the other and connected to one another, so that the finished key channel is created in this way.
