Abstract

The invention relates to a lock/key system, especially for locking systems. In order to make the unauthorised production of a key more difficult and to make the production process more economical, the profile indentations (12) of the invariant basic profile (7) assigned to the region of the key breast carrying the classifying notches, have a rectangular cross-section in the same way as the variation and system profile (8) which is shifted into the portion adjoining the key spine. Moreover, the variation and system profile (8) has at least one blocking-rib profile (11) projecting beyond the key side faces. <IMAGE>

Die Erfindung betrifft die Weiterentwicklung eines Schloß-Schlüsselsystems, insbesondere für Verschlußanlagen gemäß der Patentanmeldung P 33 40 073.The invention relates to the further development of a lock-key system, especially for locking systems according to patent application P 33 40 073.

Hierbei weisen die Schlüssel ein invariantes Grundprofil und ein Anlagen- oder Variationsprofil auf, wobei das invariante Grundprofil dem Bereich der die Einordnungskerben tragenden Schlüsselbrust zugeordnet und mit mindestens zwei die Schlüsselmittellinie überschreitenden Profilausbildungen ausgestaltet ist und wobei das Variations- oder Anlagenprofil in den dem Schlüsselrücken angrenzenden Abschnitt verlegt ist.Here, the keys have an invariant basic profile and a plant or variation profile, the invariant Basic profile assigned to the area of the key face carrying the classification notches and with at least two the Profile trainings designed to cross the key centerline and wherein the variation or system profile is relocated to the section adjacent to the back of the key.

Aufgabe der vorliegenden Weiterentwicklung war es, die unbefugte Herstellung eines Schlüssels gemäß der Hauptanmeldung weiter zu erschweren, andererseits aber den normalen Herstellungsprozeß wirtschaftlicher zu gestalten.The task of the present further development was to prevent the unauthorized production of a key according to the main application to complicate further, but on the other hand to make the normal manufacturing process more economical.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale.
20This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
20th

Vorzugsweise Weiterbildungen ergeben sich aus den Unteransprüchen .Preferably further developments result from the subclaims.

Da die Sperrippe bzw. die Sperrippen über die Schlüsselseitenflächen hinausragen, lassen sich Nachschlüssel nur schwer herstellen .Since the locking rib or the locking ribs over the key side surfaces protrude, it is difficult to produce duplicate keys.

Andererseits ergibt die vorgeschlagene im Querschnitt rechteckige Ausbildung der Profileinschnitte wesentliche Vorteile On the other hand, the proposed rectangular cross-section design of the profile incisions results in significant advantages

DaQ die gezackte Ausbildung den Zugang von Abtastwerkzeugen weitgehend verwehrt, wurde bereits in der Hauptanmeldung hervorgehoben. Since the jagged design largely prevents access to scanning tools , it was already emphasized in the main application.

Wesentlich ist aber, daß diese Ausbildung den Einsatz von Frässcheiben bei der Herstellung des Schlüssels ermöglicht, und zwar von sehr dünnen Scheiben, die entsprechend dem zu erzeugenden Profil im voraus als Satz ausgerichtet sind und somit die Profilherstellung in einem Arbeitsvorgang gewährleisten. Der Einsatz dünner Frässcheiben z.B. von 0,6 mm läßt dann natürlich auch die Erhöhung der Variationsmöglichkeiten zu, weil die verhältnismäßig kleinen Seitenflächen des Schlüssels besser ausgenutzt werden können.It is essential, however, that this training includes the use of Milling disks in the manufacture of the key allows, and indeed of very thin disks, which correspond to the generating profile are aligned in advance as a set and thus ensure the profile production in one operation. The use of thin milling disks, e.g. of 0.6 mm, then of course also increases the possibilities for variation too, because the relatively small side surfaces of the key can be better utilized.

Die beigefügte Figur zeigt im Querschnitt ein Schlüsselprofil, dessen invariantes Grundprofil mit 7 und dessen Variationsoder Anlagenprofil mit 8 bezeichnet ist. Der gestrichelt angedeutete Schlüsselkanal 10 weist einen das Arbeiten mit Abtastwerkzeugen weitestgehendst verhindernden gezackten Verlauf auf. Der Querschnitt der Profileinschnitte 12 in beiden Profilbereichen ist rechteckförrnig. Mit dem Bezugszeichen 11 sind in der Figur die über die Schlüsselseitenflächen hinausragenden Sperrippen bezeichnet.The attached figure shows in cross section a key profile, whose invariant basic profile is denoted by 7 and whose variation or system profile is denoted by 8. The one indicated by dashed lines Key channel 10 has a jagged course which prevents working with scanning tools as much as possible on. The cross section of the profile incisions 12 in both profile areas is rectangular. With the reference numeral 11 are in the figure the protruding beyond the key side surfaces Designated locking ribs.
