Description

Die Erfindung betrifft ein Schloss-Schlüsselsystem, insbesondere für Verschlussanlagen, bei dem die Schlüssel mit einem invarianten Grundprofil im Bereich der die Einordnungskerben tragenden Schlüsselbrust sowie mit mindestens zwei die Schlüsselmittellinie überschreitenden Profilausbildungen ausgestattet sind und ein Anlagen-oder Variationsprofil in dem dem Schlüsselrücken angrenzenden Abschnitt aufweisen.The invention relates to a lock and key system, in particular for locking systems, in which the keys are equipped with an invariant basic profile in the area of the key face bearing the classification notches, as well as with at least two profile designs that exceed the key center line, and have a system or variation profile in the section adjacent to the key spine .

Aus der DE-B2 25 51 523 ist beispielsweise eine derartige Anordnung der Profile, wie sie im Oberbegriff des Patentanspruchs beschrieben ist, bekannt.From DE-B2 25 51 523, for example, such an arrangement of the profiles, as described in the preamble of the claim, is known.

Auch die DE-A1 28 17 966 beschreibt invariante Grundprofile mit mindestens zwei die Schlüsselmittellinie überschreitenden Profilausbildungen.DE-A1 28 17 966 also describes invariant basic profiles with at least two profile configurations that cross the key center line.

Der Erfindung liegt nun die Aufgabe zugrunde, bei einem Schloss-Schlüsselsystem gemäss dem Oberbegriff die Abtastsicherheit weiter zu erhöhen.The invention is based on the object of further increasing the security against scanning in a lock key system.

Gelöst wird die Aufgabe erfindungsgemäss dadurch, dass das Anlagen- oder Variationsprofil mindestens ein über die Schüsselseitenflächen hinausragendes Sperrippenprofil aufweist und dass die Profileinschnitte des invarianten Grundprofils und des Anlagen- oder Variationsprofils rechteckigen Querschnitt mit einer Breite von 0,6 mm aufweisen, wobei diese durch Frässcheiben erzeugt worden sind.The object is achieved according to the invention in that the system profile or variation profile has at least one locking rib profile projecting beyond the bowl side surfaces and in that the profile incisions of the invariant basic profile and the system profile or variation profile have a rectangular cross section with a width of 0.6 mm, these being provided by milling disks have been generated.

Die Abtastsicherheit wird bei diesem Schloss-Schlüsselsystem einerseits durch die zusätzlichen Sperrippen erhöht, die über die Schlüsselseitenflächen hinausragen und andererseits ergeben sich wesentliche Vorteile für die Auftastsicherheit durch die besondere Form der Profileinschnitte.In this lock-key system, the security against scanning is increased on the one hand by the additional locking ribs which protrude beyond the key side surfaces and on the other hand there are significant advantages for the security against scanning by the special shape of the profile cuts.

Bei der DE-A1 26 37 37 516 sind zwar die Einschnitte im Zylinderkern nahezu rechteckig gezeichnet, aber für die Herstellung der Schlüssel werden Fräsköpfe verwendet, die keine rechteckigen Profilausfräsungen zulassen.In DE-A1 26 37 37 516 the incisions in the cylinder core are drawn almost rectangular, but milling heads are used for the production of the keys, which do not allow rectangular profile milling.

Werden dagegen Frässcheiben zur Herstellung der rechteckigen Querschnitte von 0,6 mm Breite benutzt, so ist nicht nur eine grosse Anzahl dieser Profileinschnitte auf engstem Raum unterbringbar, sondern auch die Sicherheit gegen Auftastversuche ist wesentlich verbessert, weil - bedingt durch die Form und Anordnung - die Zugänglichkeit erschwert ist.If, on the other hand, milling disks are used to produce the rectangular cross-sections of 0.6 mm width, not only can a large number of these profile cuts be accommodated in the smallest space, but also the security against probing attempts is significantly improved because - due to the shape and arrangement - the Accessibility is difficult.

Die Erfindung wird anhand der Ausführungsbeispiele darstellenden Figuren 2 bis 4 näher erläutert.The invention is explained in more detail with reference to FIGS. 2 to 4, which represent exemplary embodiments.

Fig. 1 zeigt den Stand der Technik, von dem die Erfindung eine Abkehr bildet. Als dieser Stand derTechnik stellt sich ein Schlüssel 1 dar, bei dem das Grundprofil 2 dem dem Schlüsselrücken 3 angrenzenden Abschnitt und das Variationsprofil 4 dem der mit Einordnungseinschnitten versehenen Schlüsselbrust 5 angrenzenden Abschnitt zugeordnet ist. In der Fig. 1 sind mögliche Profilvariationen angedeutet, und es versteht sich von selbst, dass der Schlüsselkanal im Bereich des Variationsprofils mindestens die bei 6 gestrichelt angedeutete und, in der Grundform, eine geradlinig begrenzte Öffnung aufweisen muss.Fig. 1 shows the prior art, from which the invention forms a departure. This state of the art is a key 1, in which the basic profile 2 is assigned to the section adjacent to the key back 3 and the variation profile 4 to the section adjacent to the key face 5 provided with classification incisions. Possible profile variations are indicated in FIG. 1, and it goes without saying that the key channel in the region of the variation profile must have at least the opening indicated by dashed lines at 6 and, in the basic form, a straight-line opening.

Die in den Figuren 2 bis 4 dargestellte Erfindung zeichnet sich dadurch aus, dass das invariante Grundprofil 7 in den die Einordnungskerben enthaltenden Schlüsselabschnitt 5 verlegt ist, während das Anlagen- oder Variationsprofil 8 dem schlüsselrückennahen Abschnitt, der sich bis zur Schlüsselmittenpartie erstrecken kann, angehört. In Fig. 2 ist ein des Variationsprofils weitgehendst entkleideter übergeordneter Schlüssel gezeigt, während Fig. 3 bzw. 4 Schlüssel mit angedeuteten Variationsprofilausbildungen erkennen lassen. Beiden Schlüsseln ist indessen gemeinsam, dass sie im unteren Abschnitt, nämlich dem der Schlüsselbrust 5, ein Grundprofil 7 tragen, das, wie die Ausführungsbeispiele zeigen, aus einer die Mittellinie 9 an drei Stellen überschreitenden Parazentrik besteht. Der gestrichelt angedeutete Schlüsselkanal 10 weist in diesem Abschnitt einen das Arbeiten mit Auftastwerkzeugen weitgehendst verhindernden gezackten Verlauf auf.The invention shown in FIGS. 2 to 4 is characterized in that the invariant basic profile 7 is moved into the key section 5 containing the classification notches, while the system or variation profile 8 belongs to the section near the key back, which can extend to the key center part. 2 shows a superordinate key largely undressed from the variation profile, while FIGS. 3 and 4 show keys with indicated variation profile configurations. Both keys, however, have in common that in the lower section, namely that of the key chest 5, they carry a basic profile 7 which, as the exemplary embodiments show, consists of a paracentric which crosses the center line 9 at three locations. The key channel 10, indicated by dashed lines, has a jagged course in this section, which largely prevents working with probing tools.

Auch die übrigen Profileinschnitte 12 besitzen einen rechteckigen Querschnitt. Schliesslich ist es für die Sicherheit gegen das unbefugte Öffnen des Schlosses wichtig, dass der Schlüssel wenigstens ein Sperrippenprofil aufweist, d.h. ein Profil, das über die Schlüsselflachseite hinausragt, so dass ein Nacharbeiten des Schlüssels nur durch Auftragen von Material erfolgen könnte. Bei den Ausführungen in den Figuren 2 bis 4 sind jeweils 4 Sperrippen vorgesehen.The other profile incisions 12 also have a rectangular cross section. Finally, for security against unauthorized opening of the lock, it is important that the key has at least one locking rib profile, i.e. a profile that protrudes beyond the flat side of the key, so that the key could only be reworked by applying material. In the embodiments in Figures 2 to 4, 4 locking ribs are provided.

Ein besonderer Vorteil der erfindungsgemässen Lösung sei abschliessend noch hervorgehoben. Die im Querschnitt rechteckige Ausbildung der Profileinschnitte bzw. -erhebungen ermöglicht auch eine wirtschaftliche Herstellung der Schlüssel mittels der Frässcheiben im Vergleich zu üblicherweise notwendigen Fräsköpfen, weil Frässcheiben zu beliebigen Sätzen und damit für eine beliebige Zahl von Schlüsseln zusammengestellt werden können, während Fränköpfe herkömmlicher Bauweise nur zur Herstellung eines bestimmten Schlüssels verwendbar sind.Finally, a particular advantage of the solution according to the invention should be emphasized. The rectangular cross-section of the profile cuts or elevations also enables economical production of the keys by means of the milling discs in comparison to the milling heads usually required, because milling discs can be put together in any number of sets and thus for any number of keys, whereas milling heads of conventional design only can be used to produce a specific key.
