Definitions
- the present invention relates to a method for increasing the number of combinations in the design of keys and their security locks, two grooves being provided on the flat sides of the key profile, and pairs of the same grooves being centrally symmetrical, such that the key is in opposite rotational positions can be introduced.
- the aim of the present invention to increase the number of possible combinations in the design for security locks and keys of the type mentioned above.
- This goal is achieved according to the invention in that the grooves of the keys and the cams of the locking of the locks are carried out in pairs with different dimensions. It is possible to make the grooves or auxiliary cams in different widths or diameters and / or different depths respectively. Since a key of a specific design, for example a previously common key with grooves of the same width and depth, cannot be inserted into a lock that has wider or too long tumbler cams, the full combination possibility again arises for every possible variant of the dimensions of the grooves and tumbler cams , ie the number of possible locks and keys that differ from one another can be increased to a multiple.
- the key according to FIG. 1 which corresponds to a known key in terms of its outer shape and overall dimensions, has a narrow groove 2 and a wide groove 3 on both flat sides of the key profile 1, which can be seen in particular from FIG. 3.
- Grooves of the same width and the same shape lie opposite one another in a centrally symmetrical manner with respect to the longitudinal axis of the key profile 1.
- the cams 4 and 5 are the Zu Attitudes 4 'and 5' indicated by dash-dotted lines. These cams also have different diameters, ie the cams 4 assigned to the narrow grooves 2 have smaller diameters than the cams 5 assigned to the wide grooves 3.
- the position of the grooves on the key can also be interchanged, i.e. the wider grooves 3 can take the place of the narrower grooves 2 and vice versa.
- two additional types of keys and locks are possible, i.e. the number of key and lock combinations available can be quadrupled compared to the system with equally wide grooves and tumbler cams.
- the key profile is also provided on the narrow sides with frustoconical bores 6 of different depths, which additionally increases the number of possible combinations, which can be increased even further by varying the displacements.
- the number of different types of locks and keys can be increased further by changing not only the width but also the depth of the grooves.
- FIG. 4 shows the cross section of a key profile, which is provided with grooves of different depths, namely with two deep grooves 7, which lie opposite one another in a symmetrical manner, and two shallower grooves 8 which lie opposite one another in a symmetrical sense.
- FIG. 4 also indicates that the cams 9 assigned to the deep grooves 7 are longer than the cams 10 assigned to the grooves 8. Also in this case it is not possible to insert a conventional key with two grooves of the same depth because the longer cams 9 block the insertion of the key.
- the depth of the deeper grooves 7 preferably reaches at least half, better a little more, of the key thickness.
Abstract
Der Schlüssel zu einem Sicherheitsschloss weist auf jeder Flachseite zwei Nuten auf, wobei sich Paare gleicher Nuten zentralsymmetrisch gegenüberliegen. Zwecks Erhöhung der Anzahl von Kombinationsmöglichkeiten sind die Nuten (2, 3) und die Zuhaltungs-Nocken paarweise mit verschiedenen Dimensionen ausgeführt. Dabei kann sowohl die Breite als auch die Tiefe der Nuten variieren, wobei die Breite und/oder Tiefe einer Nute jeweils gleichbleibend oder veränderlich sein kann.The key to a security lock has two grooves on each flat side, with pairs of the same grooves being centrally symmetrical. In order to increase the number of possible combinations, the grooves (2, 3) and the tumbler cams are designed in pairs with different dimensions. Both the width and the depth of the grooves can vary, the width and / or depth of a groove can in each case be constant or variable.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Erhöhung der Anzahl von Kombinationen in der Gestaltung von Schlüsseln und deren Sicherheitsschlösser, wobei an den Flachseiten des Schlüsselprofils je zwei Nuten vorgesehen sind, und wobei sich Paare gleicher Nuten zentralsymmetrisch gegenüberliegen, derart, dass der Schlüssel in entgegengesetzen Drehlagen einführbar ist. Obwohl die Anzahl möglicher Kombinationen in der Gestaltung solcher Sicherheitsschlösser und deren Schlüssel sehr hoch ist, wird doch die Kombinationsmöglichkeit einmal erschöpft und zwar vor allem in der verschiedenartigen Gestaltung von Hauptschlüsseln, die je zu einer grösseren Anzahl verschiedenartiger Schlösser passen.The present invention relates to a method for increasing the number of combinations in the design of keys and their security locks, two grooves being provided on the flat sides of the key profile, and pairs of the same grooves being centrally symmetrical, such that the key is in opposite rotational positions can be introduced. Although the number of possible combinations in the design of such security locks and their keys is very high, the combination possibility is exhausted once, especially in the different design of master keys, each of which fits a larger number of different types of locks.
Es ist das Ziel vorliegender Erfindung, für Sicherheitsschlösser und Schlüssel der obenerwähnten Art die Anzahl von möglichen Kombinationen in der Gestaltung zu erhöhen. Dieses Ziel wird gemäss der Erfindung dadurch erreicht, dass man die Nuten der Schlüssel und die Nocken der Zuhaltung der Schlösser paarweise mit verschiedenen Dimensionen ausführt. Es ist dabei möglich, die Nuten, bzw. Zuh..itungsnocken in unterschiedlicher Breite, bzw. unterschiedlichem Durchmesser und/oder verschiedener Tiefe auszuführen. Da ein Schlüssel bestimmter Ausführung, beispielsweise ein bisher üblicher Schlüssel mit Nuten gleicher Breite und Tiefe, nicht in ein Schloss eingeführt werden kann, das breitere oder zu lange Zuhaltungsnocken aufweist, ergibt sich für jede mögliche Variante der Abmessungen der Nuten und Zuhaltungsnocken wieder die volle Kombinationsmöglichkeit, d.h. die Zahl möglicher Schlösser und Schlüssel, die voneinander abweichen, kann auf ein Mehrfaches erhöht werden.It is the aim of the present invention to increase the number of possible combinations in the design for security locks and keys of the type mentioned above. This goal is achieved according to the invention in that the grooves of the keys and the cams of the locking of the locks are carried out in pairs with different dimensions. It is possible to make the grooves or auxiliary cams in different widths or diameters and / or different depths respectively. Since a key of a specific design, for example a previously common key with grooves of the same width and depth, cannot be inserted into a lock that has wider or too long tumbler cams, the full combination possibility again arises for every possible variant of the dimensions of the grooves and tumbler cams , ie the number of possible locks and keys that differ from one another can be increased to a multiple.
Die Erfindung wird nun anhand eines Ausführungsbeispiels und einer Ausführungsvariante, die in der Zeichnung dargestellt sind, näher erläutert.The invention will now be explained in more detail using an exemplary embodiment and an embodiment variant, which are shown in the drawing.
- Figur 1 zeigt eine Seitenansicht des Schlüssels mit verschieden breiten Nuten,FIG. 1 shows a side view of the key with grooves of different widths,
- Figur 2 zeigt einen Ausschnitt aus Figur 1 in grösserem Masstab,FIG. 2 shows a section of FIG. 1 on a larger scale,
- Figur 3 zeigt einen Schnitt nach Linie III-III in Figur 2, undFigure 3 shows a section along line III-III in Figure 2, and
- Figur 4 zeigt einen der Figur 3 entsprechenden Schnitt der Ausführungsvariante.FIG. 4 shows a section of the embodiment variant corresponding to FIG. 3.
Der Schlüssel nach Figur l, der in seiner äusseren Form und in seinen Gesamtabmessungen einem bekannten Schlüssel entspricht, weist an beiden Flachseiten des Schlüsselprofils 1 je eine schmale Nut 2 und eine breite Nut 3 auf, was insbesondere aus Figur 3 ersichtlich ist. Nuten gleicher Breite und gleicher Form liegen sich in Bezug auf die Längsachse des Schlüsselprofils 1 zentralsymmetrisch gegenüber. In Figur 3 sind die Nocken 4, bzw. 5 der Zuhaltungen 4', bzw. 5' in strichpunktierten Linien angedeutet. Auch diese Nocken weisen verschiedenen Durchmesser auf, d.h. die den schmalen Nuten 2 zugeordneten Nokken 4 weisen kleineren Durchmesser auf als die den breiten Nuten 3 zugeordneten Nocken 5. Es ist in diesem Falle unmöglich, einen Schlüssel mit gleichbreiten Nuten, d.h. mit Nuten, die schmäler sind als die Nocken 5 in das Schloss einzuführen. Wenn es aber möglich sein sollte, einen Schlüssel mit gleichbreiten Nuten, deren Breite zur Aufnahme der Nocken 5 genügt, in ein Schloss einzuführen, so hätten die Nocken 4 in den Schlüsselnuten Spiel, so dass die betreffenden Zuhaltungen auf keinen Fall in die vorgeschriebenen Positionen zum Drehen des Schlosszylinders gebracht würden. Es ist also unter allen Umständen Gewähr dafür geboten, dass jedes Schloss nur mit einem wirklich diesem Schloss zugeordneten Schlüssel betätigt werden kann.The key according to FIG. 1, which corresponds to a known key in terms of its outer shape and overall dimensions, has a
Die Stellung der Nuten am Schlüssel kann auch vertauscht werden, d.h. die breiteren Nuten 3 können an die Stellen der schmaleren Nuten 2 treten und umgekehrt. In dieser Weise sind zwei zusätzliche Schlüssel- und Schlossarten möglich, d.h. die Zahl der verfügbaren Schlüssel- und Schlosskombinationen kann gegenüber dem System mit gleichbreiten Nuten und Zuhaltungsnocken vervierfacht werden.The position of the grooves on the key can also be interchanged, i.e. the
Wie die Figuren 2 und 3 zeigen, ist das Schlüsselprofil auch an den Schmalseiten mit kegelstumpfförmigen Bohrungen 6 verschiedener Tiefe versehen, womit die Zahl möglicher Kombinationen zusätzlich erhöht wird, die durch die Variation der Versetzungen noch weiter erhöht werden kann.As FIGS. 2 and 3 show, the key profile is also provided on the narrow sides with
Die Zahl verschiedenartiger Schloss- und Schlüsseltypen kann weiter erhöht werden, indem nicht nur die Breite, sondern auch die Tiefe der Nuten verändert wird. InThe number of different types of locks and keys can be increased further by changing not only the width but also the depth of the grooves. In
Figur 4 ist der Querschnitt eines Schlüsselprofils dargestellt, das mit verschieden tiefen Nuten, nämlich mit zwei zentralsymmetrisch gegenüberliegenden, tieferen Nuten 7 und zwei zentralsymmetrisch gegenüberliegenden, flacheren Nuten 8 versehen ist. In Figur 4 ist ebenfalls angedeutet, dass die den tiefen Nuten 7 zugeordneten Nocken 9 länger sind, als die den Nuten 8 zugeordneten Nocken 10. Auch in diesem Falle ist es nicht möglich, einen herkömmlichen Schlüssel mit zwei gleichtiefen Nuten einzuführen, weil die längeren Nocken 9 die Einführung des Schlüssels sperren. Vorzugsweise erreicht die Tiefe der tieferen Nuten 7 mindestens die Hälfte, besser etwas mehr, der Schlüsseldicke.FIG. 4 shows the cross section of a key profile, which is provided with grooves of different depths, namely with two deep grooves 7, which lie opposite one another in a symmetrical manner, and two
Es ist weiterhin möglich, weitere Schloss- und Schlüsselvarianten in der Weise zu schaffen, dass die Nuten und Nocken in der Breite und Tiefe variiert werden.It is also possible to create further lock and key variants in such a way that the grooves and cams are varied in width and depth.
Es ist dabei schliesslich auch möglich, jeweils paarweise die Breite und/oder Tiefe innerhalb einer Nut zu variieren, wobei selbstverständlich die Nut am Einlauf breiter und/oder tiefer als hinten sein muss.Finally, it is also possible to vary the width and / or depth in pairs within a groove, the groove at the inlet naturally having to be wider and / or deeper than the rear.
Die beschriebenen Massnahmen zur Erhöhung möglicher Kombinationen von Schlüsseln und zugeordneten Sicherheitsschlössern hat nicht nur den Vorteil, die Anzahl möglicher Kombinationen auf ein Mehrfaches zu erhöhen, sondern es wird damit auch klar ausgeschlossen, dass ungenaue Schlüsselnachahmungen überhaupt in das Schloss eingeführt werden können. Damit wird die Gefahr stark herabgesetzt, dass Schlösser durch die Verwendung ungenauer Schlüsselkopien beschädigt werden oder dass ungenaue Schlüsselkopien zwar eingeführt werden können, die Betätigung des Schlosses aber nicht erlauben.The described measures for increasing possible combinations of keys and assigned security locks not only have the advantage of increasing the number of possible combinations by a multiple, but also clearly preclude the possibility that imprecise key imitations can be inserted into the lock at all. This greatly reduces the risk of locks being damaged by the use of inaccurate key copies or that inaccurate key copies can be inserted but do not allow the lock to be operated.
Ausserdem wird bei der Verwendung von Nuten, deren Tiefe mindestens die Hälfte der Schlüsseldicke ausmacht, die Nachahmung wesentlich erschwert, wenn nicht verunmöglicht.In addition, when using grooves the depth of which is at least half the key thickness, imitation is made considerably more difficult, if not impossible.
