Description

Die Erfindung betrifft ein Flachschlüsselprofil für ein Schloss-Schlüssel-System, bei dem im Schließzylinder ein mit dem Schlüsselprofil korrespondierender Schlüsselkanal vorgesehen ist.The invention relates to a flat key profile for a lock and key system in which a key channel corresponding to the key profile is provided in the lock cylinder.

Unter dem Begriff Flachschlüssel werden auch Rippenprofilschlüssel oder Sperr-RippenprofilSchlüssel verstanden, also solche Profile, bei denen Rippen über die Schlüsselseitenfläche vorstehen.The term flat key is also understood to mean rib profile keys or locking rib profile keys, ie those profiles in which ribs protrude beyond the key side surface.

Schlüssel werden aus den verschiedensten Gründen nachgemacht oder kopiert, wobei man unterscheiden muss, ob legal oder illegal.Keys are mimicked or copied for a variety of reasons, with a distinction being made between legal and illegal.

Das Kopieren wird durch solche Schlüsselprofile erschwert oder soll zumindest erschwert werden, dadurch, dass es sich um geschützte Profile handelt, also solche, denen ein Patent - oder Gebrauchsmusterschutz zuerkannt worden ist.Copying is made more difficult by such key profiles or at least made more difficult by the fact that they are protected profiles, ie those which have been granted patent or utility model protection.

Für derartige Schlüssel besteht die Möglichkeit der Nachbestellung über den Schlosshersteller oder autorisierte Schlüsseldienste.For such keys there is the possibility of reordering via the lock manufacturer or authorized locksmiths.

Andererseits ist es bekannt, dass Schlüsseldienste auch durch den Einsatz von Kopiermaschinen in der Lage sind, Nachschlüssel herzustellen, die an sich geschützte Profile aufweisen. Allerdings gibt es Profile, bei denen dies nicht so einfach ist und daher durch Vereinfachungen eine Annäherung an das tatsächliche Profil versucht wird. Hierzu zählt beispielsweise die Form der seitlichen Profilnuten.On the other hand, it is known that locksmiths are also able, through the use of copying machines, to produce duplicates having profiles protected on their own. However, there are profiles for which this is not so easy and therefore an approximation to the actual profile is attempted by simplifications. This includes, for example, the shape of the lateral profile grooves.

Bei handelsüblichen Kopiermaschinen kommt nämlich ein dünnes Kreissägeblatt zur Anwendung, das nur rechtwinklige Einschnitte in den Schlüssel vornehmen kann. Werden für die Kopie V-förmige Einschnitte verlangt, so kann als Ersatz nur ein rechteckiger Einschnitt vorgenommen werden.In commercial copying machines, namely, a thin circular saw blade is used, which can only make right-angled cuts in the key. If V-shaped cuts are required for the copy, only a rectangular cut can be made as a replacement.

Aufgabe der Erfindung ist es nun, die maschinelle Kopierbarkeit eines Schlüsselprofils zu erschweren.The object of the invention is now to complicate the machine copying a key profile.

Gelöst wird diese Aufgabe erfindungsgemäß durch ein Flachschlüsselprofil für ein Schloss-Schlüssel-System, bei dem im Schließzylinder ein mit dem Schlüsselprofil korrespondierender Schlüsselkanal vorgesehen ist,
dadurch,

  • dass das Schlüsselprofil des Schlüsselschaftes einen dem Schlüsselrücken zugewandten oberen Profilabschnitt und einen der Schlüsselbrust zugewandten unteren Profilabschnitt aufweist,
  • dass ausgehend von der Schlüsselbrust in der Schlüsselschaftebene in den unteren Profilabschnitt ragende Kerben vorgesehen sind,
  • dass im unteren Profilabschnitt in der einen Seitenfläche des Schlüsselschaftes eine dreieckförmige, die Mittelebene des Schlüsselschaftes überragende, parazentrische Profilnut 2 vorgesehen ist,
  • dass auf der gegenüberliegenden Seitenfläche des Schlüsselschaftes eine oberhalb oder eine unterhalb der gegenüberliegenden parazentrischen Profilnut angeordnete, dreieckförmige Profilnut vorgesehen ist, deren Profilgrund einen horizontalen Abstand zum Profilgrund der gegenüberliegenden parazentrischen Profilnut hat,
  • dass die Anordnung der parazentrischen Profilnut bezogen auf die gegenüber liegenden Profilnuten derart ist, dass eine gedachte Linie die senkrecht zur Schlüsselschaftebene vom Schnittpunkt des oberen oder unteren Schenkels der parazentrischen Profilnut mit der Schlüsselseitenfläche zur gegenüberliegenden Profilnut verläuft, zu einer gedachten Linie die sich vom Schnittpunkt des oberen oder unteren Schenkels der gegenüberliegenden Profilnut mit der Schlüsselseitenfläche bis zur parazentrischen Profilnut erstreckt, einen vertikale Abstand hat .
This object is achieved according to the invention by a flat key profile for a lock and key system, in which a key channel corresponding to the key profile is provided in the lock cylinder,
thereby,
  • the key profile of the key shank has an upper profile section facing the key back and a lower profile section facing the key chest,
  • in that projecting notches are provided in the lower profile section starting from the key-breast in the key-shaft plane,
  • a triangular, paracentric profile groove 2 projecting beyond the median plane of the key shank is provided in the lower profile section in the one side face of the key shank,
  • a triangular profile groove arranged above or below the opposite paracentric profile groove is provided on the opposite side surface of the key shank, the profile base of which has a horizontal distance from the profile base of the opposite paracentric profile groove,
  • the arrangement of the paracentric profile groove relative to the opposing profile grooves is such that an imaginary line perpendicular to the keychain plane from the intersection of the upper or lower leg of the paracentric profile groove with the key side surface to the opposite profile groove, to an imaginary line extending from the intersection of upper or lower leg of the opposite profile groove with the key side surface extends to the paracentric profile groove, has a vertical distance.

Vorzugsweise Ausgestaltungen ergeben sich aus den Unteransprüchen.Preferably embodiments emerge from the subclaims.

Zur Anwendung kommen zwei sich gegenüberliegende Profilmerkmale, die dreieckig (V-förmig) ausgebildet sind. Die Profilmerkmale sind symmetrisch und haben in ihrem Grund Radien.Two opposing profile features are used, which are triangular (V-shaped). The profile features are symmetrical and have radii in their base.

Wenn zwei gegenüberliegende Merkmale nun so angeordnet sind, dass sie sich bei rechtwinklig gefrästen Profilen sehr nahe kommen, dann würde der Schlüssel in diesem Bereich brechen. Die Mindest-Überschneidung sollte bei 0,2mm liegen und die maximale Restdicke bei 0,3mm. Um die dreieckigen Einschnitte (Profilmerkmale) wirtschaftlich herstellen zu können, sollte der tiefere Einschnitt einen Winkel von a=110° haben.If two opposing features are now arranged so that they are very close to each other with profiles milled right-angled, then the key would break in this area. The minimum overlap should be 0.2mm and the maximum residual thickness 0.3mm. In order to produce the triangular cuts (profile features) economically, the deeper notch should have an angle of a = 110 °.

Es müssen mindestens zwei Einschnitte sein, die sich versetzt gegenüberliegen. Ausgehend vom tieferen Einschnitt muss also entweder "über" oder "unter" diesem ein weiterer Einschnitt vorhanden sein.There must be at least two incisions that are offset from each other. Starting from the deeper incision, either "above" or "below" this one further incision must be present.

Da - wie oben erwähnt - die Kopiermaschine mit einer rechteckigen Frässcheibe keine V-förmige Profilnut erzeugen kann, muss als Ersatz die Profilnut rechteckig gefräst werden, wodurch sie zwangsläufig breiter wird.Since, as mentioned above, the copying machine with a rectangular milling disc can not produce a V-shaped profile groove, the profile groove must be milled rectangular as a replacement, whereby it is inevitably wider.

Da nun aber erfindungsgemäß weitere Anordnungszusammenhänge oder -merkmale beachtet werden müssen, führt dies dazu, dass der Schlüsselschaft an bestimmten Stellen zu dünn wird, so dass er beim Kopiervorgang oder spätestens bei der Benutzung bricht.Since, however, according to the invention further arrangement relationships or features must be taken into account, this leads to the key shank becoming too thin at certain points, so that it breaks during the copying process or at the latest during use.

Es wird somit der Nachteil von mechanischen Profilkopiermaschinen ausgenutzt, so dass der kopierte Schlüssel nicht benutzbar ist.
Auch das Kopieren mit Filament-3D Druckern wird durch die Schrägen deutlich erschwert, da sich hier die Schrägen nur stufenförmig erzeugen lassen.Thus, the disadvantage of mechanical profile copying machines is exploited, so that the copied key is not usable.
Even copying with 3D filament printers is made much more difficult by the bevels, as here the bevels can only be generated stepwise.

Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen näher erläutert werden.The invention will be explained in more detail with reference to the drawings.

Der Schlüsselschaft ist mit 1 bezeichnet. Von der Schlüsselseitenfläche geht die tiefere Profilnut 2 aus, die parazentrisch sich über die Mittelebene erstreckt. Die Profilnut 2 ist symmetrisch ausgebildet und hat die Winkel Alpha (a). Desgleichen sind die Profilnuten "über" - und "unter" der Profilnut 2 auf der anderen Schlüsselseite ausgebildet. Diese sind mit 3 und 4 gekennzeichnet und haben einen Winkel Beta (ß). Am Grund der Einschnitte gibt es einen Radius (R).
Um die drei Einschnitte ist jeweils mit gestrichelten Linien 5, 6, 7 ein Rechteck gezeichnet, dass die rechtwinkligen Einschnitte mittels einer mechanischen Profilkopiermaschine darstellt.The key shaft is labeled 1. From the key side surface, the deeper profile groove 2 goes out, which extends paracentrally over the median plane. The profile groove 2 is formed symmetrically and has the angle alpha (a). Likewise, the profile grooves are formed "over" and "under" the profile groove 2 on the other key side. These are marked 3 and 4 and have an angle beta (ß). At the bottom of the incisions, there is a radius (R).
To the three incisions each with dashed lines 5, 6, 7 is drawn a rectangle that represents the rectangular incisions by means of a mechanical profile copying machine.

Im Einzelnen ist die Anordnung der parazentrischen Profilnut bezogen auf die gegenüber liegenden Profilnuten derart, dass eine gedachte Linie 7, die senkrecht zur Schlüsselschaftebene vom Schnittpunkt des oberen oder unteren Schenkels der parazentrischen Profilnut mit der Schlüsselseitenfläche zur gegenüberliegenden Profilnut verläuft, zu einer gedachten Linie 5, die sich vom Schnittpunkt des oberen oder unteren Schenkels der gegenüberliegenden Profilnut mit der Schlüsselseitenfläche bis zur parazentrischen Profilnut erstreckt, einen vertikalen Abstand 9 hat .In detail, the arrangement of the paracentric profile groove with respect to the opposite profile grooves is such that an imaginary line 7, perpendicular to the key plane from the intersection of the upper or lower leg of the paracentric profile groove with the key side surface to the opposite profile groove, to an imaginary line 5, which extends from the intersection of the upper or lower leg of the opposite profile groove with the key side surface to the paracentric profile groove, a vertical distance 9 has ,

Hier ergeben sich somit horizontale und vertikale Abstände. Der horizontale Abstand 8 sollte maximal 0,3mm sein, die vertikale Überdeckung 9 minimal 0,2mm betragen.
Der Winkel Alpha vom tieferen Einschnitt soll 110° betragen. Der Radius R soll 0,2mm betragen. Der Winkel Beta ist entsprechend der Abstände 8 und 9 frei wählbar.
Vorzugsweise sollten die Einschnitte (Profilmerkmale) im "unteren" Bereich des Schlüssels liegen, also in dem - von der Schlüsselbrust ausgehend - gekerbt wird.This results in horizontal and vertical distances. The horizontal distance 8 should be a maximum of 0.3mm, the vertical coverage 9 minimum 0.2mm.
The angle alpha from the deeper incision should be 110 °. The radius R should be 0.2mm. The angle beta is freely selectable according to the distances 8 and 9.
The incisions (profile features) should preferably lie in the "lower" area of the key, ie in which - starting from the key breast - is notched.
