Description

Die Erfindung betrifft einen Schlüssel für Zylinderschlossschließanlage, wobei in den Schlüsselflachseiten Längsnuten vorgesehen sind, deren Anordnung und Querschnitt zur Erzeugung von Schließvariationen variierbar sind und wobei wenigstens eine tiefe Variationsnut in der Form einer Längsnut vorgesehen ist, deren Querschnittsform der Fläche oder einer Teilfläche eines Basisdreiecks entspricht, dessen Basisseite in der Schlüsselflachseite liegt, von der sich die beiden anderen Seiten zu einer Kreuzungslinie erstrecken, wobei eine der Nutenflanken auch die Seitenhalbierende der Basisseite des Basisdreiecks bilden kann, sodass im Basisdreieck zwei tiefe Variationsnuten anordbar sindThe invention relates to a key for cylinder lock system, wherein in the key flat sides are provided longitudinal grooves whose arrangement and cross-section are variable to produce closing variations and wherein at least one deep Variationsnut is provided in the form of a longitudinal groove whose cross-sectional shape corresponds to the surface or a partial surface of a base triangle whose base side lies in the key flat side, from which the other two sides extend to a crossing line, wherein one of the groove flanks can also form the side bisector of the base side of the base triangle, so that two deep variation grooves can be arranged in the base triangle

Die Erfindung geht aus von der Längsprofilierung von Schlüssel und zugehörigem Schlüsselkanal des Schlosses, wie beispielsweise der AT 371 879 und AT 385 076 zu entnehmen ist. Die Aufgabe derartiger Schlüssel und Schlösser besteht in erster Linie darin, eine große Vielzahl von Variationsmöglichkeiten zu schaffen, sowie die missbräuchliche Nachahmung zu erschweren. Trotz möglichst großer Variationsmöglichkeiten ist es wünschenswert, die Unterschiede zwischen den einzelnen Variationen möglichst groß zu halten, um Fehlsperrungen zufolge Materialabnützung oder Herstellungsungenauigkeiten zu vermeiden.The invention is based on the longitudinal profiling of the key and associated key channel of the lock, such as the AT 371 879 and AT 385 076 can be seen. The task of such keys and locks is primarily to create a wide variety of possible variations, as well as to complicate the abusive imitation. Despite the greatest possible variation, it is desirable to keep the differences between the individual variations as large as possible in order to avoid incorrect blocking due to material wear or manufacturing inaccuracies.

Bei der vorliegenden Erfindung kommt hinzu, dass von den bekannten Schlössern und Schlüsseln, die unter der Markenbezeichnung "GPI" laufen, Millionen Schlösser und Schlüssel montiert oder vertrieben wurden, wobei es wünschenswert sein kann, bestehende Schließanlagen auszubauen, wobei die neu hinzukommenden Profilelemente kompatibel mit den bestehenden Elementen sein sollen.In addition, in the present invention, of the known locks and keys running under the "GPI" brand, millions of locks and keys have been assembled or sold, and it may be desirable to remove existing locking systems, the newly added profile elements being compatible with should be the existing elements.

Die gewünschten Ziele werden gemäß vorliegender Erfindung durch den Kennzeichnenden Teil des Anspruchs 1 erreicht.The desired objects are achieved according to the present invention by the characterizing part of claim 1.

Weitere Merkmale des Schlüssels und des Schlossprofils sind den Patentansprüchen und der nachfolgenden Beschreibung und den Zeichnungen zu entnehmen.Further features of the key and the lock profile can be found in the patent claims and the following description and the drawings.

Nachfolgend wird die Erfindung beispielsweise anhand der Zeichnungen beschrieben. Fig. 1 ist die Seitenansicht eines Flachschlüssels. Die Fig. 2 zeigt das Schema der Profilbildung im Querschnitt. Fig. 3 zeigt die verschiedenen Variationen für die erfindungsgemäßen Profilnuten und Fig. 4 ein Querschnittsschema für einen Schlüssel mit allen Variationsmöglichkeiten, erfindungsgemäße Variationsmöglichkeiten und Variationsmöglichkeiten nach dem Stand der Technik, für die Längsprofilnuten, wobei der erfindungsgemäße Schlüssel mindestens eine seichte Nut aufweist. Fig. 5 und 6 sind Beispiele für Schlüsselprofile, wobei in Fig. 5 auch das Profil des Schlüsselkanals eingezeichnet ist. Fig. 7 zeigt ein weiteres Beispiel für das Nutenschema gemäß Fig. 2.The invention will be described by way of example with reference to the drawings. Fig. 1 is the side view of a flat key. The Fig. 2 shows the scheme of profile formation in cross section. Fig. 3 shows the various variations for the profile grooves according to the invention and Fig. 4 a cross-sectional diagram of a key with all possible variations, inventive variations and variations of the prior art, for the Längsprofilnuten, wherein the key according to the invention has at least one shallow groove. Fig. 5 and 6 are examples of key profiles, where in Fig. 5 also the profile of the key channel is located. Fig. 7 shows another example of the slot scheme according to Fig. 2 ,

Gemäß Fig. 1 weist der Schlüssel an einer oder beiden Schlüsselflachseiten 1 Längsnuten 2, 3 auf. Die Schlüsselbrust 4 ist in bekannter Weise mit den Einschnittfräsungen 5 versehen, die im Schloss hier nicht dargestellte Stiftzuhaltungen betätigen. Der Schlüsselrücken ist mit 6 bezeichnet und der Schlüsselgriff trägt das Bezugszeichen 7.According to Fig. 1 has the key on one or both key flat sides 1 longitudinal grooves 2, 3. The key-breast 4 is provided in a known manner with the Einschnittfräsungen 5, which operate in the lock not shown here pin tumblers. The key back is denoted by 6 and the key handle bears the reference numeral 7.

Jede der variierbaren Längsnuten 3 ist nach dem Schema ausgebildet, wie in Fig. 2 eingezeichnet. Das Basisdreieck ist mit starker Linie ausgezogen und durch die zwei Seiten 8, 9 sowie die der Seitenfläche des Schlüsselrohlings entsprechende Linie 17 gebildet. Diese Seiten 8, 9 schneiden sich in der Kreuzungslinie 10. Im Schlüssel erstreckt sich die Kreuzungslinie 10 über die gesamte Schaftlänge des Schlüssels parallel zur Schlüsselflachseite 1.Each of the variable longitudinal grooves 3 is formed according to the scheme as in Fig. 2 located. The base triangle is drawn with a strong line and formed by the two sides 8, 9 and the side surface of the key blank corresponding line 17. These sides 8, 9 intersect at the intersection line 10. In the key, the intersection line 10 extends over the entire shaft length of the key parallel to the key flat side. 1

Bekannt ist es aus den zuvor genannten Druckschriften, die Basisdreiecke durch die Seitenhalbierende 11 der Basisseite zu teilen, sodass drei Variationsmöglichkeiten in bekannter Weise zur Verfügung stehen.It is known from the aforementioned documents to divide the base triangles by the side bisector 11 of the base side, so that three variations are available in a known manner.

Gemäß vorliegender Erfindung können zusätzlich noch zwei Nutenflanken vorgesehen werden, die so angeordnet sind, dass sie entlang der Seitenhalbierenden 121, 131 der Seiten 8, 9 verlaufen, die jeweils eine der Seiten 8 oder 9 halbieren und durch den der Seite 8, 9 gegenüberliegenden Eckpunkt gehen, d.h. der Schwerlinie der Seite 8, 9 entsprechen, wie es in Fig. 2 eingezeichnet ist.According to the present invention additionally two flanks can be provided, which are arranged so that they extend along the side bisectors 121, 131 of the sides 8, 9, each bisecting one of the sides 8 or 9 and through the side 8, 9 opposite corner go, ie the line of gravity of page 8, 9 correspond to how it is in Fig. 2 is drawn.

Das Nutenschema gemäß Fig. 2 zeigt alle möglichen Variationen in einer einzigen Basisnut. In der Praxis ergeben sich daraus die in Fig. 3 gezeichneten Nutentypen a bis d sowie ab und cd. Die Variation ab entspricht dem Basisdreieck. Es können somit ausgehend von einem einzigen Basisdreieck sechs Profilvariationen gebildet werden, wodurch sich die Zahl der Variationen erheblich steigert. Trotz der hohen Zahl dieser Variationsmöglichkeiten sind die Querschnittsflächen der einzelnen Variationselemente groß genug, um die nötige Schließsicherheit zu bieten. Die in Fig. 3 nach links offenen Längsnuten können an der anderen Schlüsselflachseite nach rechts offen ebenfalls angeordnet sein.The groove scheme according to Fig. 2 shows all possible variations in a single basic groove. In practice, this results in the Fig. 3 drawn groove types a to d and from and cd. The variation ab corresponds to the base triangle. It can thus be formed from a single base triangle six profile variations, which significantly increases the number of variations. Despite the large number of these variations, the cross-sectional areas of the individual variation elements are large enough to provide the necessary closing security. In the Fig. 3 to the left open longitudinal grooves can also be arranged on the other key flat side to the right open.

Die Fig. 5 zeigt beispielsweise den Schnitt durch einen kompletten Schlüssel, wobei auf der linken Seite drei Variationsnuten und auf der rechten Seite zwei Variationsnuten 3 eingezeichnet sind. Die entlang des Schlüsselrückens 6 angeordnete Längsprofilnut 2 wird aus Platzgründen nicht in der beschriebenen Weise variiert, sondern wird bevorzugt immer gleich tief ausgebildet.The Fig. 5 shows, for example, the section through a complete key, three Variationsnuten on the left side and two Variationsnuten 3 are drawn on the right side. The along the key back 6 arranged Längsprofilnut 2 is not varied for reasons of space in the manner described, but is preferably always the same depth formed.

Wie in den Figuren 4, 5 und 6 zu erkennen ist, erstrecken sich die Längsprofilnuten 2, 3 über die Mittellängsebene 112 des Schlüssels hinaus, sodass durchwegs ein überlapptes Profil ausgebildet werden kann. Von überlappten Profilen spricht man dann, wenn an wenigstens drei Stellen die Längsprofilnuten bis an die Mittellängsebene 112 heranreichen oder diese überschreiten. Die Kreuzungslinien 10 liegen, wie man im Schema von Fig. 4 erkennt, jeweils auf der anderen Seite der Mittellängsebene 112 und zwar in Schnittstellenebenen 113, die parallel zur Mittellängsebene 112 verlaufen.As in the FIGS. 4, 5 and 6 can be seen, the Längsprofilnuten 2, 3 extend beyond the central longitudinal plane 112 of the key, so that throughout an overlapped profile can be formed. The term "overlapped profiles" is used when the longitudinal profiled grooves reach or exceed the center longitudinal plane 112 at at least three points. The crossing lines 10 are, as shown in the scheme of Fig. 4 detects, in each case on the other side of the central longitudinal plane 112 and that in interface planes 113 which extend parallel to the central longitudinal plane 112.

In bevorzugter Weise ist der Innenwinkel 14 jedes Basisdreiecks stets der gleiche und die Seitenlängen des Basisdreiecks sowie deren Seitenhalbierungen sind jeweils von den Schlüsselflachseiten 1 gemessen. Letzteres trifft auch dann zu, wenn gemäß Fig. 4 ein sogenanntes konisches Profil vorgesehen ist. Dabei verläuft über zumindest einen Teil der Schlüsselhöhe die Umhüllende 15 schräg zur Mittellängsebene 112. Durch diese konische Ausbildung des Schlüsselquerschnitts wird sichergestellt, dass am Schlüsselbart der zugehörige Schließkanal des Zylinderschlosses enger ausgebildet sein kann, um missbräuchliches Sperren zu behindern. Weiters erschwert die konische Ausbildung das Nachmachen des Schlüssels.Preferably, the inner angle 14 of each base triangle is always the same and the side lengths of the base triangle and their side halves are each measured from the key flat sides 1. The latter applies even if according to Fig. 4 a so-called conical profile is provided. In this case, the envelope 15 extends obliquely to the central longitudinal plane 112 over at least part of the key height. This conical design of the key cross section ensures that the associated keyway of the cylinder lock can be made narrower in order to hinder abusive blocking. Furthermore, the conical training complicates the copying of the key.

Die Fig. 5 zeigt ein Beispiel für die Variationen d, a und c an der linken und c, b an der rechten Schlüsselseitenfläche. Das zugehörige Profil des Schlüsselkanals 1b ist strichliert eingezeichnet. Die Fig. 6 zeigt links die Variationen,b, d und a sowie rechts cd und a.The Fig. 5 shows an example of the variations d, a and c on the left and c, b on the right key side surface. The associated profile of the key channel 1b is shown by dashed lines. The Fig. 6 shows the variations on the left, b, d and a and on the right cd and a.

Die Fig. 7 zeigt eine Ausbildung des Nutenschemas analog der Fig. 2, die in der Praxis bevorzugt ist. Diese Form berücksichtigt die beim Herstellen der Längsnuten und im Gebrauch erforderlichen Spiele zwischen den aneinandergleitenden Metallflächen.The Fig. 7 shows an embodiment of the Nutenschemas analogous to Fig. 2 , which is preferred in practice. This shape takes into account the required clearance between the sliding metal surfaces in forming the longitudinal grooves and in use.

Es versteht sich von selbst, dass die Profilierungen im zugehörigen Schlüsselkanal des Schlosses analog dem Schlüsselprofil ausgebildet sein müssen. Im einfachsten Fall entspricht eine Längsprofilnut im Schlüssel einer Längsprofilrippe im Schlüsselkanal. Jedenfalls muss das Gesamtprofil des Schlüsselkanals immer so groß sein, dass das Querschnittsprofil des Schlüssels hineinpasst.It goes without saying that the profiles must be formed in the associated key channel of the lock analogous to the key profile. In the simplest case corresponds to a Längsprofilnut in the key of a longitudinal profile rib in the keyway. In any case, the overall profile of the keyway must always be so large that the cross-sectional profile of the key fits.

Mit dem vorliegenden Profilierungssystem kann auch der Nachteil bestehender früherer Systeme geheilt werden. Da es im Laufe der Zeit zu Verlusten von Schlüsseln gekommen ist, ist die Sicherheit nicht mehr gewährleistet. Es können nunmehr neue Schlüssel ausgegeben werden, die zusätzlich zu den bestehenden Nuten a oder b eine der seichten Nuten c oder d oder cd besitzen. Sicherheitsrelevante Schließzylinder, z. B. in der Außenhaut eines Gebäudes, werden dann gegen neue Schließzylinder ausgetauscht, die an einer bestimmten vorgewählten Position nur eine der Rippen aufweisen, die im Schlüssel den seichten Nuten c oder d oder cd entsprechen. Damit ist es möglich, dass die neuen Schlüssel alle Zylinder sperren, nämlich die alten und neuen Schließzylinder, wo die Sicherheitsrelevanz nicht so hoch ist. Nach Austausch der sicherheitsrelevanten Zylinder können diese neuen Schließzylinder nur von den neuen Schlüsseln gesperrt werden. Damit wird der schließtechnische Wert einer Schließanlage mit geringerem Aufwand wiederhergestellt, als er bei einem Gesamtaustausch aller Schließzylinder und Schlüssel nötig wäre.With the present profiling system, the disadvantage of existing earlier systems can be cured. Since there has been a loss of keys over time, the security is no longer guaranteed. New keys can now be issued which, in addition to the existing grooves a or b, have one of the shallow grooves c or d or cd. Security relevant lock cylinder, z. B. in the outer skin of a building, are then exchanged for new lock cylinder having only one of the ribs at a certain preselected position corresponding to the shallow grooves c or d or cd in the key. This makes it possible for the new keys to lock all cylinders, namely the old and new lock cylinders, where the safety relevance is not so high. After replacing the safety-relevant cylinders, these new lock cylinders can only be locked by the new keys. Thus, the closing technical value of a locking system is restored with less effort than it would be necessary for a total replacement of all lock cylinder and key.

Weiters ist es mit dem erfindungsgemäßen Profilierungssystem möglich, Gruppenschlüsselanlagen zu erweitern. Bestehende Gruppenschlüsselanlagen haben eine fixe Struktur, deren Erweiterung nicht ohne Probleme möglich ist. Mit den Rippen analog den seichten Nuten c und d oder cd können jetzt zusätzliche Gruppenschlüssel gebildet werden. So ist es gewährleistet, dass neue Schlüssel mit den seichten Nuten c, d oder cd nicht in bestehende Zylinder hineinsperren, die eine der Rippen gemäß den Längsnuten a oder b aufweisen.Furthermore, it is possible with the profiling system according to the invention to expand group key systems. Existing group key systems have a fixed structure whose extension is not possible without problems. With the ribs analogous to the shallow grooves c and d or cd, additional group keys can now be formed. Thus, it is ensured that new keys with the shallow grooves c, d or cd do not lock into existing cylinders having one of the ribs according to the longitudinal grooves a or b.

Weiters ist es möglich, Hauptschlüsselanlagen problemlos zu erweitern. Mit den seichten Nuten c und d oder cd können zusätzliche Eigenschlüssel in der Hauptschlüsselanlage gebildet werden. So können Hauptschlüsselanlagen leicht erweitert werden ohne die bestehende Struktur der Anlage zu beeinflussen.Furthermore, it is possible to easily expand master key systems. With the shallow grooves c and d or cd additional self-key can be formed in the master key system. Thus, master key systems can easily be extended without affecting the existing structure of the system.
