Definitions
- the invention relates to a flat key for cylinder locks according to the features of the preamble of claim 1.
- the object of the present invention is to meet the requirements mentioned above and to provide a profile arrangement which allows the production of individual keys, that is to say unique, keys, thus keys have no hierarchical connection with one another. In the case of such unique items, it is not possible to convert one profile into another profile of the same profile system by post-processing.
- FIGS. 1 to 7 show the side view of a flat key with grooves on a flat side of the key.
- FIGS. 2 to 12 show schematic sectional representations according to section line II.
- FIGS. 2 and 3 schematically show two known profile arrangements or profile systems.
- Fig. 4 shows schematically the profile cross-section grid and
- Fig. 5 shows the three basic groove types A, B and C.
- Figs. 6, 7 show two different profile designs.
- 8 and 9 show schematically the profile system for the possible groove arrangements in one row of the profile cross-sectional grid.
- 10, 11 and 12 show exemplary embodiments of flat keys according to the invention, the profile formation of the associated key channel being additionally drawn in FIG.
- Fig. 1 shows a conventional flat key in side view.
- Longitudinal grooves extend in a known manner from the key chalk 1 to the key tip 2.
- the grooves are provided on both flat sides and are distributed over the height 3 of the key profile in accordance with the desired variation.
- the incisions 4 interact in a known manner with tumbler pins, not shown here, of the associated cylinder lock.
- the number of incisions 4 can be chosen as desired, but usually ranges between three and seven incisions.
- profile systems have been proposed, such as shown in Figs. 2 and 3.
- 2 provides profile elements 5 to 11 on the left key side and profile elements 12 to 18 on the right key side, which can be milled out of the key material depending on the desired variation.
- a key produced in this way, in which the profile elements 6, 9, 11, 14 and 16 have been milled out, is drawn out with a strong line in the profile cross-sectional grid.
- the invention proceeds in a known manner from a grid of the key cross-section, which is divided into several lines 25 to 29, FIG. 4. Each of these lines can be provided with one of the three profile types, which are labeled A, B and C in FIG.
- the longitudinal central plane of the key is designated 30 in each case.
- the profile type A has a relatively deep groove 31 which starts from the left flat side of the key and protrudes over the longitudinal center plane 30. The right flat side remains full.
- Profile type B also has a relatively deep groove 32, which extends from the right side of the key over the longitudinal center plane 30. The left flat side remains full.
- Profile type C has relatively flat grooves 33 on both flat sides.
- All three profile types A, B and C have grooves with dimensions such that the remaining key material is strong enough to ensure a stable key.
- the exact cross-sectional shape of the individual profile types is in itself irrelevant for the basic system. The number of profile variations can be increased by choosing different profile shapes.
- the profile types A, B and C can be arranged as desired over the key height within the grid Fig. 4, at least two of the profile types A, B or C being realized on a flat key.
- FIG. 6 shows the profile sequence B-B-C-A-C and FIG. 7 shows a key with the profile sequence A-B-A-C-A. If you look at these key profiles, you can clearly see that it is not possible to rework any of the profile elements by removing key material in such a way that a profile element of another profile type is created, which results in a usable key. Such non-executable options are shown in broken lines in FIG. With all these possibilities, the key breaks apart along the grooves and is therefore unusable. In the first column, Fig. 6, the additional milling of a groove A would overlap with the existing groove B and the key would be cut lengthways.
- the flat key is characterized by the features of claim 1.
- Profile elements of an embodiment according to the invention are drawn in a raster line.
- each of these types of grooves can be formed on the key only in a separate line of the profile cross-sectional grid.
- the grooves to be incorporated are arranged asymmetrically to the line symmetry plane 34 within each line.
- the embodiment in FIG. 9 is mirror image of the embodiment in FIG. 8.
- the two symmetry variations can be present on a key, as can be seen in FIGS. 11 and 12.
- the line consists of an upper and lower boundary line 35, 36.
- the left and right boundary lines correspond to the key flat sides 37, 38.
- Two diagonals are possible within the rectangle formed in this way, the embodiment of Fig. 8 the diagonal 39 from the left used top to bottom right as a construction line, while in the embodiment according to FIG. 9 the diagonal 40 runs from top right to bottom left.
- the upper groove flank 41 extends in the line diagonal 39 for the groove type A. If a type B groove is to be provided which extends from the right flat key side 38, it is the lower groove flank 42 which is in or approximately in the line diagonal 39 lies.
- Both grooves A and B have a depth that extends over the longitudinal center plane 30 of the key.
- a so-called. overlapped profile can be achieved, which increases the locking safety in a known manner.
- the dashed lines 43, 44 are the boundary lines of the grooves according to type C in FIG. 8. As can be seen, the shape of the flat grooves of type C corresponds exactly to the shape of the grooves of type A and B, only the depth of the groove is shortened.
- the embodiment according to FIG. 9 is self-evident on the basis of the explanation relating to FIG. 8.
- the groove types are designated A1, B1 and C1.
- the individual profile lines are separated from one another by line gaps 45 in order to provide enough key material for the ribs which remain in this way as profile elements between the grooves.
- the key flat sides 37, 38 run obliquely in the direction of the longitudinal central plane of the key, whereby a so-called. conical profile is provided.
- the height of the individual rows varies along a key height and decreases towards the key face.
- key profiles are drawn in cross section throughout. It goes without saying that such profiles are provided both on the finished key and on the key blank, the finished key being produced from the key blank by milling grooves for the pin tumblers.
- the design of the key channel profiles of associated locks must also be carried out analogously, as is self-evident for the skilled person.
- the profile arrangement according to the present invention thus relates in the same way to flat keys and blank keys.
- the key 46 is inserted into the associated key channel 47 of an associated lock, which is not shown in detail.
- a groove in the key corresponds to a correspondingly designed rib of the key channel.
- a major advantage of the construction according to the invention is that a large number of individual keys (unique pieces) can be systematically produced.
- these are approximately 750 key profiles, which differ from one another to a considerable extent, the smallest difference between two key profiles having a sufficiently large cross-section so that there is a high level of security against locking.
- Previously known key profiles had to make do with about 60 unique profiles.
- the 750 key profiles mentioned can still be increased if more lines are used.
- the key cross-sectional shape can meet the requirements be modified accordingly.
- the back of the key 48 is adapted to the radius of the cylinder core, that is to say it is curved in cross section.
- the incisions 4 for the pin tumblers are located in the area of the key chest (reference number 49 in FIG. 10), so that the ribs and grooves of the key profile are omitted at the locations of these incisions, depending on the incision depth.
Description
Die Erfindung betrifft einen Flachschlüssel für Zylinderschlösser gemäß den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a flat key for cylinder locks according to the features of the preamble of
Für die gewerbliche Herstellung von Flachschlüssel für Zylinderschlösser ist es notwendig, die Profilierung der Schlüsselflachseiten nach einem gewissen System auszubilden. Bei verschiedenen Schlüsseln ist es oft gewünscht, daß sie auch verschiedene Profilierungen tragen, damit sie nicht in andere Zylinderschlösser des gleichen Profilsystems eingesteckt werden können.For the commercial production of flat keys for cylinder locks, it is necessary to profile the key flat sides according to a certain system. With different keys, it is often desirable that they also have different profiles so that they cannot be inserted into other cylinder locks of the same profile system.
Andererseits besteht aus Kostengründen die Notwendigkeit, die maschinelle Umstellung für die Erzeugung verschiedener Schlüsselprofile möglichst einfach und kostengünstig zu gestalten. Es sollen also möglichst wenig verschiedene Profilelemente zur Verwendung kommen.On the other hand, for reasons of cost, there is a need to make the mechanical changeover for generating different key profiles as simple and inexpensive as possible. As little as possible different profile elements should be used.
Aufgabe der vorliegenden Erfindung ist es, den oben genannten Forderungen nachzukommen und eine Profilanordnung vorzusehen, welche die Herstellung von Einzelschlüsseln, also von Unikaten, gestattet, somit von Schlüsseln, die miteinander in keinerlei hierarchischem Zusammenhang stehen. Bei solchen Unikaten ist es nicht möglich, durch Nachbearbeitung das eine Profil in ein anderes Profil des gleichen Profilsystems überzuführen.The object of the present invention is to meet the requirements mentioned above and to provide a profile arrangement which allows the production of individual keys, that is to say unique, keys, thus keys have no hierarchical connection with one another. In the case of such unique items, it is not possible to convert one profile into another profile of the same profile system by post-processing.
Im folgenden wird der Stand der Technik anhand der Fig.1 bis 7 und die Erfindung anhand der Fig. 8 bis 12 näher erläutert. Fig.1 zeigt die Seitenansicht eines Flachschlüssels mit Nuten an einer Flachseite des Schlüssels. Die folgenden Fig.2 bis 12 zeigen schematische Schnittdarstellungen gemäß der Schnittlinie I-I. Die Fig. 2 und 3 zeigen schematisch zwei bekannte Profilanordnungen bzw. Profilsysteme. Fig.4 zeigt schematisch das Profilquerschnittsraster und Fig.5 die drei grundsätzlichen Nuttypen A,B und C. Die Fig.6,7 zeigen zwei verschiedene Profilausführungen. Die Fig.8 und 9 zeigen schematisch die Profilsystematik für die möglichen Nutanordnungen in jeweils einer Zeile des Profilquerschnittsrasters. Die Fig. 10, 11 und 12 zeigen Ausführungsbeispiele erfindungsgemäßer Flachschlüssel, wobei in Fig.12 zusätzlich die Profilausbildung des zugehörigen Schlüsselkanals eingezeichnet ist.The prior art is explained in more detail below with reference to FIGS. 1 to 7 and the invention with reference to FIGS. 8 to 12. 1 shows the side view of a flat key with grooves on a flat side of the key. The following FIGS. 2 to 12 show schematic sectional representations according to section line II. FIGS. 2 and 3 schematically show two known profile arrangements or profile systems. Fig. 4 shows schematically the profile cross-section grid and Fig. 5 shows the three basic groove types A, B and C. Figs. 6, 7 show two different profile designs. 8 and 9 show schematically the profile system for the possible groove arrangements in one row of the profile cross-sectional grid. 10, 11 and 12 show exemplary embodiments of flat keys according to the invention, the profile formation of the associated key channel being additionally drawn in FIG.
Fig. 1 zeigt einen üblichen Flachschlüssel in Seitenansicht. Von der Schlüsselreide 1 erstrecken sich in bekannter Weise Längsnuten bis zur Schlüsselspitze 2. Die Nuten sind an beiden Flachseiten vorgesehen und entsprechend der gewünschten Variation über die Höhe 3 des Schlüsselprofils verteilt. Die Einschnitte 4 wirken in bekannter Weise mit hier nicht dargestellten Zuhaltungsstiften des zugehörigen Zylinderschlosses zusammen. Die Anzahl der Einschnitte 4 kann beliebig gewählt werden, bewegt sich aber zumeist zwischen drei und sieben Einschnitten.Fig. 1 shows a conventional flat key in side view. Longitudinal grooves extend in a known manner from the
Bisher wurden Profilsysteme vorgeschlagen, wie z.B. in den Fig. 2 und 3 dargestellt. Das Profilquerschnittsraster gemäß Fig. 2 sieht auf der linken Schlüsselseite Profilelemente 5 bis 11 und auf der rechten Schlüsselseite Profilelemente 12 bis 18 vor, die je nach gewünschter Variation aus dem Schlüsselmaterial ausgefräst werden können. Ein so hergestellter Schlüssel,bei dem die Profilelemente 6, 9, 11, 14 und 16 ausgefräst wurden, ist in dem Profilquerschnittsraster mit starker Linie ausgezogen.So far, profile systems have been proposed, such as shown in Figs. 2 and 3. 2 provides
Bei einem anderen bekannten Profilsystem gemäß Fig. 3 wird analog vorgegangen, indem z.B. die Profilelemente 19, 21 und 24 ausgefräst sind.In another known profile system according to FIG. 3, the procedure is analogous, for example by the
Alle diese bekannten Profiltypen bzw. Profilsysteme weisen Nachteile auf. Einmal ist es relativ leicht möglich, aus einem bestimmten Profil durch Abfräsen ein anderes Profil des gleichen Profilsystems herzustellen, das dann entsprechende andere Schlösser sperren kann. Wird z.B. in den stark ausgezogenen Schlüssel gemäß Fig. 2 nachträglich das Profilelement 7 weggenommen, wobei die entstehende Nut die beiden Profilelemente 6 und 7 umfaßt, wird ein voll funktionsfähiger neuer Schlüssel hergestellt, der dem gleichen Profilsystem entspricht und alle zugehörigen Schlösser sperren kann. Auch bei dem in Fig. 3 mit starker Linie eingezeichneten Schlüssel kann z.B. durch Wegnahme des Profilelementes 22 ein geänderter,voll funktionsfähiger Schlüssel gebildet werden. Solche Profiländerungen sind für entsprechend ausgerüstete Betriebe keine Schwierigkeit, und ein Mißbrauch ist dadurch leicht möglich.All these known profile types or profile systems have disadvantages. On the one hand, it is relatively easy to mill another profile of the same profile system from a certain profile, which can then lock corresponding other locks. If, for example, the
Weiters haben alle bekannten derartigen Profilsysteme den Nachteil, daß es relativ einfach ist - soferne die Profilsystematik bekannt ist - einen übergeordneten Schlüssel herzustellen, der praktisch in alle Schlösser oder Gruppen von Schlössern nach diesem Profilsystem paßt. Bei der Profilsystematik Fig.3 geschieht dies z.B. dadurch, daß der Nachschlüssel Nuten erhält, bei denen alle Felder 19 bis 24 ausgefräst sind. Wird ein solcher Schlüssel zur Verfügung gestellt, werden alle der Sicherheit dienenden Profilunterschiede zunichte gemacht.Furthermore, all known profile systems of this type have the disadvantage that it is relatively simple - provided the profile system is known - to produce a superordinate key which fits practically in all locks or groups of locks according to this profile system. With the profile system Fig. 3 this happens e.g. in that the duplicate key has grooves in which all
Die Erfindung geht in bekannter Weise von einem Raster des Schlüsselquerschnitts aus, der in mehrere Zeilen 25 bis 29 gegliedert ist, Fig.4. Jede dieser Zeilen kann mit einem der drei Profiltypen versehen werden, die in Fig.5 mit A, B und C bezeichnet sind. Die Längsmittelebene des Schlüssels ist jeweils mit 30 bezeichnet.The invention proceeds in a known manner from a grid of the key cross-section, which is divided into
Die Profiltype A weist eine verhältnismäßig tiefe Nut 31 auf, die von der linken Schlüsselflachseite ausgeht und über die Längsmittelebene 30 ragt. Die rechte Flachseite bleibt voll.The profile type A has a relatively
Die Profiltype B weist ebenfalls eine verhältnismäßig tiefe Nut 32 auf, die sich von der rechten Schlüsselseite über die Längsmittelebene 30 erstreckt. Die linke Flachseite bleibt voll.Profile type B also has a relatively
Die Profiltype C weist an beiden Flachseiten verhältnismäßig flache Nuten 33 auf.Profile type C has relatively
Alle drei Profiltypen A, B und C weisen Nuten mit derartiger Dimension auf, daß das verbleibende Schlüsselmaterial genügend stark ist, um einen stabilen Schlüssel zu gewährleisten. Die genaue Querschnittsform der einzelnen Profiltypen ist für das grundsätzliche System an und für sich unerheblich. Durch Wahl verschiedener Profilformen kann die Zahl der Profilvariationen noch erhöht werden.All three profile types A, B and C have grooves with dimensions such that the remaining key material is strong enough to ensure a stable key. The exact cross-sectional shape of the individual profile types is in itself irrelevant for the basic system. The number of profile variations can be increased by choosing different profile shapes.
Die Profiltypen A, B und C können beliebig über die Schlüsselhöhe innerhalb des Rasters Fig.4 angeordnet werden, wobei an einem Flachschlüssel wenigstens zwei der Profiltypen A, B oder C verwirklicht sind.The profile types A, B and C can be arranged as desired over the key height within the grid Fig. 4, at least two of the profile types A, B or C being realized on a flat key.
In den Fig.6, 7 sind beispielsweise zwei verschiedene so ausgebildete Profile dargestellt. Fig. 6 zeigt die Profilfolge B-B-C-A-C und Fig.7 einen Schlüssel mit der Profilfolge A-B-A-C-A. Sieht man sich diese Schlüsselprofile an, so erkennt man deutlich, daß es nicht möglich ist, irgendeines der Profilelemente durch Wegnahme von Schlüsselmaterial so umzuarbeiten, daß dadurch ein Profilelement einer anderen Profiltype entsteht, die einen gebrauchsfähigen Schlüssel ergibt. In Fig.6 sind strichliert derartige nicht ausführbare Möglichkeiten eingezeichnet. Bei allen diesen Möglichkeiten bricht der Schlüssel entlang der Nuten auseinander und wird dadurch gebrauchsunfähig. In der ersten Spalte Fig.6 würde das zusätzliche Einfräsen einer Nut A mit der bestehenden Nut B überlappen und den Schlüssel der Länge nach auftrennen. In der zweiten Spalte würde das Einfräsen des linken Teils der Nuttype C eine so geringe Wandstärke bis zur bestehenden Nut B ergeben, daß der Schlüssel an dieser Stelle bricht. Auch die Umarbeitung eines Profiltyps C (dritte Spalte in Fig.6) würde eine zu geringe Schlüsselwandstärke ergeben und den Schlüssel gebrauchsunfähig machen.6, 7, for example, two different profiles designed in this way are shown. 6 shows the profile sequence B-B-C-A-C and FIG. 7 shows a key with the profile sequence A-B-A-C-A. If you look at these key profiles, you can clearly see that it is not possible to rework any of the profile elements by removing key material in such a way that a profile element of another profile type is created, which results in a usable key. Such non-executable options are shown in broken lines in FIG. With all these possibilities, the key breaks apart along the grooves and is therefore unusable. In the first column, Fig. 6, the additional milling of a groove A would overlap with the existing groove B and the key would be cut lengthways. In the second column, milling the left part of the groove type C would result in such a small wall thickness up to the existing groove B that the key breaks at this point. The reworking of a profile type C (third column in Fig. 6) would also result in an insufficient key wall thickness and render the key unusable.
Derartige Schlüsselprofile können einem Schlüsselkatalog "Börkey, Zylinder-, Auto- und Kreuz- Schlüssel-Katalog, Ausgabe 1972" entnommen werden. Zum Stand der Technik wird weiters auch auf die AT-B-371 879 verwiesenSuch key profiles can be found in a key catalog "Börkey, cylinder, auto and cross-key catalog, edition 1972". With regard to the prior art, reference is also made to AT-B-371 879
Gemäß vorliegender Erfindung ist der Flachschlüssel durch die Merkmale des Anspruches 1 gekennzeichnet.According to the present invention, the flat key is characterized by the features of
Die Fig. 8 und 9 zeigen im vergrößerten Maßstab alle möglichen8 and 9 show all possible on an enlarged scale
Profilelemente einer erfindungsgemäßen Ausführungsform in einer Rasterzeile eingezeichnet. In der Praxis kann am Schlüssel jede dieser Nuttypen nur in einer eigenen Zeile des Profilquerschnittrasters ausgebildet sein.Profile elements of an embodiment according to the invention are drawn in a raster line. In practice, each of these types of grooves can be formed on the key only in a separate line of the profile cross-sectional grid.
Anders als bei den zuvor gezeigten Ausführungen Fig. 5 bis 7 sind die einzuarbeitenden Nuten hier innerhalb jeder Zeile unsymmetrisch zur Zeilensymmetrieebene 34 angeordnet. Die Ausführung Fig. 9 ist um die Ebene 34 spiegelbildlich zur Ausführung Fig. 8. An einem Schlüssel können beide Symmetrievariationen vorhanden sein, wie in den Fig. 11 und 12 ersichtlich ist.In contrast to the embodiments shown in FIGS. 5 to 7, the grooves to be incorporated are arranged asymmetrically to the
In Fig. 8 besteht die Zeile aus einer oberen und unteren Begrenzungslinie 35, 36. Die linken und rechten Begrenzungslinien entsprechen den Schlüsselflachseiten 37, 38. Innerhalb des so gebildeten Rechtecks sind zwei Diagonalen möglich, wobei die Ausführung Fig. 8 die Diagonale 39 von links oben nach rechts unten als Konstruktionslinie benutzt, während bei der Ausführung gemäß Fig. 9 die Diagonale 40 von rechts oben nach links unten verläuft.In Fig. 8 the line consists of an upper and
In Fig. 8 verläuft bei dem Nutentyp A die obere Nutenflanke 41 in der Zeilendiagonale 39. Soll eine Nut der Type B vorgesehen werden, die sich von der rechten Flachschlüsselseite 38 erstreckt, ist es die untere Nutenflanke 42, die in oder annähernd in der Zeilendiagonale 39 liegt.In FIG. 8, the
Beide Nuten A und B weisen eine Tiefe auf, die über die Längsmittelebene 30 des Schlüssels reicht. Damit kann in Zusammenwirken mit gleichartigen Profilelementen anderer Zeilen ein sogen. überlapptes Profil erzielt werden, was die Nachsperrsicherheit in an sich bekannter Weise erhöht.Both grooves A and B have a depth that extends over the
Die strichlierten Linien 43, 44 sind die Begrenzungslinien der Nuten gemäß Typ C in Fig. 8. Wie man sieht, entspricht die Form der flachen Nuten des Typs C genau der Form der Nuten des Typs A und B, wobei nur die Tiefe der Nut verkürzt ist.The dashed
Die Ausbildung gemäß Fig. 9 versteht sich anhand der Erläuterung zu Fig. 8 von selbst. Die Nutentypen sind mit A1, B1 und C1 bezeichnet.The embodiment according to FIG. 9 is self-evident on the basis of the explanation relating to FIG. 8. The groove types are designated A1, B1 and C1.
In Hinblick auf die obigen Ausführungen wird nochmals hervorgehoben, daß am Schlüssel innerhalb einer Zeile immer nur eine der Nutentypen A, B oder C bzw. A1, B1 oder C1 angeordnet sein kann. Über die verschiedenen Zeilen entlang der Höhe eines Schlüssels können die verschiedenen Profiltypen Fig. 8, 9 aber beliebig miteinander kombiniert sein.With regard to the above, it is emphasized once again that only one of the groove types A, B or C or A1, B1 or C1 can be arranged on the key within a line. The different profile types FIGS. 8, 9 can, however, be combined with one another as desired via the different lines along the height of a key.
Durch die asymmetrische Anordnung der Nuten innnerhalb einer Zeile wird die Variationsmöglichkeit erheblich vergrößert, da die spiegelbildliche Verwendung möglich ist. Dabei ist gewährleistet, daß sich die einzelnen Schlüsselprofile stark genug voneinander unterscheiden, um Fehlsperrungen zu vermeiden.As a result of the asymmetrical arrangement of the grooves within a line, the possibility of variation is considerably increased, since mirror-image use is possible. This ensures that the individual key profiles differ enough from one another to avoid incorrect locking.
Die Fig. 10 bis 12 zeigen beispielsweise drei verschiedene Schlüsselquerschnitte mit Profilanordnungen gemäß vorliegender Erfindung. Es sei nochmals darauf hingewiesen, daß keines dieser Schlüsselprofile durch irgendeine spanabhebende Nachbearbeitung in ein anderes Profil der gleichen Profilsystematik übergeführt werden kann, ohne auseinanderzubrechen.10 to 12 show, for example, three different key cross sections with profile arrangements according to the present invention. It should be pointed out again that none of these key profiles can be converted into another profile of the same profile system by any subsequent machining without breaking apart.
Die einzelnen Profil zeilen sind voneinander durch Zeilenzwischenräume 45 getrennt, um zwischen den Nuten als Profilelemente genügend Schlüsselmaterial für die so stehenbleibenden Rippen vorzusehen. Ab der zweiten Zeile verlaufen die Schlüsselflachseiten 37, 38 schräg in Richtung zur Längsmittelebene des Schlüssels, wodurch ein sogen. konisches Profil vorgesehen wird.The individual profile lines are separated from one another by
Die Höhe der einzelnen Zeilen variiert entlang einer Schlüsselhöhe und nimmt zur Schlüsselbrust hin ab.The height of the individual rows varies along a key height and decreases towards the key face.
In den Fig. 10 bis 12 sind durchwegs Schlüsselprofile im Querschnitt eingezeichnet. Es versteht sich von selbst, daß derartige Profile sowohl am fertigen Schlüssel als auch am Schlüsselrohling vorgesehen werden, wobei aus dem Schlüsselrohling durch Einfräsen von Nuten für die Stiftzuhaltungen erst der fertige Schlüssel hergestellt wird. Die Ausbildung der Schlüsselkanalprofile zugehöriger Schlösser muß ebenfalls analog erfolgen, wie dies für den Fachmann selbstverständlich ist. Die Profilanordnung gemäß vorliegender Erfindung betrifft somit in gleicher Weise Flachschlüssel und Schlüsselrohling.10 to 12, key profiles are drawn in cross section throughout. It goes without saying that such profiles are provided both on the finished key and on the key blank, the finished key being produced from the key blank by milling grooves for the pin tumblers. The design of the key channel profiles of associated locks must also be carried out analogously, as is self-evident for the skilled person. The profile arrangement according to the present invention thus relates in the same way to flat keys and blank keys.
In Fig. 12 ist der Schlüssel 46 in den zugehörigen Schlüsselkanal 47. eines zugehörigen, aber nicht weiter dargestellten Schlosses gesteckt eingezeichnet. Einer Nut im Schlüssel entspricht dabei jeweils eine entsprechend ausgebildete Rippe des Schlüsselkanals.In FIG. 12, the key 46 is inserted into the associated
Ein wesentlicher Vorteil der erfindungsgemäßen Konstruktion liegt darin, daß eine große Zahl von Einzelschlüsseln (Unikaten) systematisch hergestellt werden kann. Bei den Ausführungsbeispielen gemäß Fig. 10 bis 12 sind dies etwa 750 Schlüsselprofile, die sich voneinander in erheblichem Umfang unterscheiden, wobei nämlich der geringste Unterschied zwischen zwei Schlüsselprofilen einen genügend großen Querschnitt aufweist, sodaß eine hohe Sperrsicherheit vorliegt. Bisher bekannte Schlüsselprofile mußten mit etwa 60 Unikatprofilen auskommen. Die genannten 750 Schlüsselprofile können bei Verwendung von mehr Zeilen weiterhin vermehrt werden.A major advantage of the construction according to the invention is that a large number of individual keys (unique pieces) can be systematically produced. In the exemplary embodiments according to FIGS. 10 to 12, these are approximately 750 key profiles, which differ from one another to a considerable extent, the smallest difference between two key profiles having a sufficiently large cross-section so that there is a high level of security against locking. Previously known key profiles had to make do with about 60 unique profiles. The 750 key profiles mentioned can still be increased if more lines are used.
Weiters wird auf den Vorteil hingewiesen, daß zu keiner der erfindungsgemäßen Profilanordnungen ein übergeordneter Schlüssel hergestellt werden kann und daß die einzelnen Unikatschlüssel nicht in andere Schlüssel des gleichen Profilsystems übergeführt werden können.Furthermore, it is pointed out to the advantage that a superordinate key cannot be produced for any of the profile arrangements according to the invention and that the individual unique keys cannot be converted into other keys of the same profile system.
Die Darstellungen in den Zeichnungen sind rein schematisch gehalten. In der Praxis kann die Schlüsselquerschnittsform den Anforderungen entsprechend abgeändert sein. So wird z.B. der Schlüsselrücken 48 dem Radius des Zylinderkerns angepaßt, d.h. im Querschnitt gebogen sein. Im Bereich der Schlüsselbrust (Bezugszeichen 49 in Fig. 10) liegen die Einschnitte 4 für die Stiftzuhaltungen, sodaß an den Stellen dieser Einschnitte je nach Einschnittiefe die Rippen und Nuten des Schlüsselprofils wegfallen.The illustrations in the drawings are purely schematic. In practice, the key cross-sectional shape can meet the requirements be modified accordingly. For example, the back of the key 48 is adapted to the radius of the cylinder core, that is to say it is curved in cross section. The incisions 4 for the pin tumblers are located in the area of the key chest (
Claims (4)
