Für das Ausarbeiten von Schließanlagen ist eine solche Profilierung besonders wertvoll, da eine hohe Anzahl voneinander unabhängiger Variationsstellen vorgesehen werden kann, wobei der Schlüssel dennoch verschleißsicher bleibt.This arrangement previously proposed by the applicant (WO 93/09317) shows one on the key flat side additionally superimposed over a conventional longitudinal profile Oblique profiling. For working out Such locking systems are particularly valuable for locking systems, because a large number of mutually independent variation points can be provided with the key nevertheless remains wear-resistant.
Mit der vorliegender Erfindung sollen die Vorteile des bekannten Profilsystems noch verstärkt werden, indem die Variationszahl beträchtlich erhöht und die mechanische Stabilität des Schlüssels ausreichend hoch gehalten wird.With the present invention, the advantages of known profile system can be reinforced by the Variation number increased considerably and the mechanical Stability of the key is kept sufficiently high.
Die gegenständliche Erfindung ist dadurch gekennzeichnet, daß an jeder der Schlüsselflachseiten wenigstens eine Schrägprofilnut vorgesehen ist, wobei sich die Schrägprofilnuten der beiden Flachseiten eines Schlüssels oder deren Verlängerungslinie einander im Raum kreuzen, daß der Schlüssel im Einschnittbereich der Schlüsselbrust mindestens vier Längsnuten aufweist, die jeweils die Mittellängsebene überragen und daß im Bereich des Schlüsselrückens wenigstens eine Längsnut vorgesehen ist, deren Profilnutengrund mit dem in bevorzugter Weise kreisbogenförmigen Profilnutengrund der Schrägprofilnut(en) zusammenfällt. Bevorzugt wird die unterste und die oberste der mindestens 4 Längsnuten im Einschnittbereich für das Ausbilden von Schließanlagen nicht variiert, während die beiden mittleren Längsnuten hinsichtlich Lage und Anordnung variabel sind. Weitere können die Schrägprofilnuten an jeder Schlüsselflachseite in zwei Gruppen angeordnet sein, wobei jede Gruppe zur Ausbildung von Variationen bevorzugt 5 Steuerstellen und somit maximal 5 Schrägprofilnuten aufweisen. Dies ergibt insgesamt 20 Steuerstellen für die Variation.The subject invention is characterized in that that at least one on each of the key flat sides Inclined profile groove is provided, the inclined profile grooves of the two flat sides of a key or whose extension line cross each other in space that the key in the incision area of the key face has at least four longitudinal grooves, each of the central longitudinal plane tower and that in the area of the key back at least one longitudinal groove is provided, the bottom of the profile groove with the circular arc in the preferred manner Profile groove base of the oblique profile groove (s) coincides. The lowest and the uppermost of the at least are preferred 4 longitudinal grooves in the incision area for the formation of Locking systems did not vary, while the two middle ones Longitudinal grooves are variable in terms of location and arrangement. The angled profile grooves on each key flat side can be used be arranged in two groups, each Group for the formation of variations, preferably 5 control points and thus have a maximum of 5 inclined profile grooves. This results in a total of 20 control points for the variation.
Im folgenden wird die Erfindung anhand einiger Ausführungsbeispiele näher erläutert. Fig. 1 zeigt die Seitenansicht eines erfindungsgemäßen Schlüssels. Fig. 2 zeigt schematisch eine bevorzugte Ausführungsform der Profilsystematik und die Fig. 3 und 4 zeigen zwei Ausführungsbeispiele für erfindungsgemäße Profile. Die Fig. 5, 6 und 7 sind Querschnitte durch ein Zylinderschloß mit eingeschobenem Schlüssel und die Fig. 8 bis 11 zeigen die den Schlüssel seitlich abtastende Organe.In the following, the invention is based on a few exemplary embodiments explained in more detail. Fig. 1 shows the side view of a key according to the invention. Fig. 2 shows schematically a preferred embodiment of the profile system and Figs. 3 and 4 show two embodiments for profiles according to the invention. 5, 6 and 7 are cross sections through a cylinder lock with inserted Key and FIGS. 8 to 11 show the key laterally scanning organs.
Gemäß Fig. 1 umfaßt der Flachschlüssel 1 den Schlüsselschaft
2 und die Reide 3. Die Höhe des Schlüsselschaftes
setzt sich zusammen aus dem Einschnittbereich 4 und dem
Rückenbereich 5. Jede der Schlüsselflachseiten 6 weist zwei
Typen von Profilierungen auf. Zum einen liegt eine herkömmliche
Längsprofilierung vor, die in Richtung der Einschubrichtung
des Schlüssels liegt. In Fig. 1 ist diese Längsprofilierung
an der einen Schlüsselflachseite durch die
drei Längsnuten 7 gegeben.1, the flat key 1 comprises the
Weitere sind in zwei Gruppen Schrägprofilnuten 8 vorgesehen,
die hinsichtlich Lage und Vorhandensein oder nicht
Vorhandensein variabel sind. Die Schrägprofilnuten sind gegenüber
der Einschubrichtung des Schlüssels schräg gestellt
und durch die Verlängerungslinie 9 ist die winkelmäßige
Ausrichtung zur Senkrechten auf den Schlüsselrücken
dargestellt. Wenn an einer Schlüsselflachseite mehrere
Schrägprofilnuten 8 vorgesehen sind, sind diese zueinander
parallel, wobei die auf der anderen Schlüsselflachseite
angeordneten Schrägprofilnuten bzw. deren Verlängerungslinien

Der zuvor beschriebene Einschnittbereich 4 ist jener Bereich,
in dem von der Schlüsselbrust 38 aus die Einschnitte
11 zur Steuerung von Zuhaltungsstiften maximal reichen
können. Beispielsweise kann jede der eingezeichneten fünf
Einschnitte 11 zehn verschiedene Variationstiefen aufweisen
(siehe auch Fig. 4).The incision area 4 described above is the area
in which the incisions from the
In Fig. 2 ist die neue und erfindungsgemäße Profilanordnung
hinsichtlich seiner Systematik dargestellt. Im Einschnittbereich
liegen die vier Längsprofilnuten 12, 13, 14 und 15.
Die Nuten überragen stets die Mittellängsebene 16, sodaß
das Profil im Einschnittbereich durchgehend überlappt ist.
Die Längsprofilnuten 12 und 15 sind innerhalb einer Profilserie
immer gleich hinsichtlich Lage und Form vorgesehen,
während die Längsprofilnuten 13 und 14 in ihrer Anordnung
der Lage nach variabel sind, wie weiter unten noch
erläutert wird.2 is the new profile arrangement according to the invention
presented in terms of its system. In the incision area
are the four
Weitere ist in Fig. 2 schematisch der Profilnutengrund 17
der Schrägprofilnut 8 eingezeichnet. Der Profilnutengrund
17 ist bogenförmig, insbesondere als Kreissegment ausgebildet.
Der Profilnutengrund 17 endet jeweils in der zugehörigen
Schlüsselflachseite 6 oder in der Längsprofilnut
14. Damit ist gewährleistet, daß der Kantenbereich 39 des
Schlüsselrückens 18 glatt verläuft.The
Im Rückenbereich 5 des Schlüsselprofils können zur Variation
an jeder Schlüsselflachseite zwei Längsprofilnuten 19,
20 vorgesehen werden. Der Profilnutengrund 21 dieser Längsprofilnuten
fällt mit dem Profilnutengrund 17 der Schrägprofilnuten
8 zusammen. Die Profiltiefe zum Schlüsselrücken
18 hin wird immer flacher. In the
Durch diese Maßnahme wird in vorteilhafter Weise erreicht, daß der Schlüssel die notwendige mechanische Stabilität beibehält und dies auch dann, wenn eine Variation des Schlüssels viele Ausfräsungen erfordert, wodurch eine "zerklüftete" Profilierung entsteht, bei der relativ viel Schlüsselmaterial weggenommen ist.This measure advantageously achieves that the key has the necessary mechanical stability maintains this even if a variation of the Key requires many millings, creating one "Rugged" profiling arises with which a relatively large amount Key material is taken away.
Mit dem Bezugszeichen 22 sind rein schematisch Abtastelemente
des Schlosses eingezeichnet, mit denen das Vorhandensein
oder nicht Vorhandensein der Schrägprofilnuten 8
abgetastet wird.With the
Die Fig. 3 und 4 zeigen zwei verschiedene Profilvarianten
nach dem Schema der Fig. 2 in Form des Schlüsselkanals. Das
Schlüsselprofil ist analog ausgebildet.3 and 4 show two
Fig. 4 zeigt die sechs Variationsstellen der Längsprofilnuten. Die vier möglichen Längsprofilnuten a, b, d und e können wahlweise vorgesehen oder nicht vorgesehen werden. An den Variationsstellen c und f ist immer eine überlappte Längsnut vorgesehen, wobei jedoch die Lage der Höhe nach variiert werden kann, wodurch sich jeweils eine Variationsstelle ergibt.Fig. 4 shows the six points of variation of the longitudinal profile grooves. The four possible longitudinal profile grooves a, b, d and e can either be provided or not provided. There is always an overlap at the variation points c and f Longitudinal groove provided, but the position according to the height can be varied, resulting in a variation point results.
Fig. 3 zeigt die Variante mit den Längsprofilnuten a, d und e, sowie den oberen Teilen der Profilnuten c und f.Fig. 3 shows the variant with the longitudinal profile grooves a, d and e, and the upper parts of the profile grooves c and f.
Fig. 4 zeigt eine Variation, wo schlüsselseitig die Profilnuten d und e sowie die jeweils unteren Teile der Profilnuten c und f Verwendung finden. Den Profilnuten am Schlüssel entsprechen selbstverständlich Kernrippen des Schlüsselkanals.Fig. 4 shows a variation where the profile grooves on the key side d and e and the lower parts of the profile grooves c and f are used. The profile grooves on the key naturally correspond to core ribs of the key channel.
In Fig. 4 sind auch die beispielsweise möglichen Einschnittfräsungstiefen 39 eingezeichnet, die wahlweise für das Steuern von Zuhaltungsstiften vorgesehen sein können (Fig. 1, Bezugszeichen 11).4 also shows the incision milling depths that are possible, for example 39 drawn, the optional for the control of tumbler pins can be provided (Fig. 1, reference numeral 11).
Die dargestellte und beschriebene Profilsystematik sieht im Schlüsselkanal sechs beliebig variierbare Rippen (a - f) vor. Um den Schlüsselkanal im Rückenbereich nicht zu offen zu halten, kann in der Praxis auch auf eine Variation verzichtet werden, wobei z.B. die Kernrippe d immer vorgesehen wird. In diesem Fall stehen dann nur fünf Rippen für die Kombination zur Verfügung, denen am Schlüssel fünf Längsprofilnuten entsprechen.The profile systematics shown and described looks in Key channel six freely variable ribs (a - f) in front. In order not to open the key channel in the back area in practice, a variation can be dispensed with , e.g. the core rib d is always provided becomes. In this case there are only five ribs for the Combination available with five longitudinal profile grooves on the key correspond.
Wenn in bevorzugter Weise die Schrägprofilierung an jeder
Schlüsselflachseite 2 Gruppen zu je 5 Variationsstellen
aufweist, was maximal 20 Schrägprofilnuten bedeuten kann,
ergibt sich mit den fünf variablen Längsprofilen eine Variationszahl
von etwa 35,5 Millionen verschiedene Profile.
Dies kann noch mit den Variationszahlen der Einschnittfräsungen
für jeden der Zuhaltungsstifte multipliziert
werden. Es ergibt sich so eine äußerst hohe Variationszahl,
wobei die einzelnen Variationsstellen unabhängig voneinander
einsetzbar sind. Der Schlüsselquerschnitt gewährleistet
dabei in jedem Fall genügend hohe Stabilität. Das analoge
Schlüsselkanalprofil des Schlosses ist vor allem im kritischen
Bereich der Einschnittfräsungen stark geschwungen und
als überlapptes Profil ausgebildet, wodurch das Nachsperren
erheblich erschwert wird.If preferred, the oblique profile on everyone

Der in Fig. 3 dargestellte Schlüsselkanal ist im Rückenbereich in vorteilhafter Weise eng, da die Kernrippen a, d und e vorgesehen sind. Bei der Variation gemäß Fig. 4 sind die Kernrippen a und b nicht vorhanden, wodurch das Profil im Rückenbereich mehr geöffnet ist. In der Praxis wird in bevorzugter Weise wenigstens die Kernrippe d und im vorliegenden Fall beide Rippen d und e vorgesehen, um das Abtasten des Schlosses zu erschweren und den Schlüssel beim Einschieben besser zu führen.The key channel shown in Fig. 3 is in the back area advantageously narrow because the core ribs a, d and e are provided. 4 are the core ribs a and b are absent, creating the profile is more open in the back area. In practice, in preferably at least the core rib d and in the present Case both ribs d and e provided to the Palpation of the lock difficult and the key when To guide insertion better.
Ein Vergleich beispielsweise der Rippen (oder der analogen
Nuten am Schlüssel) mit dem Bezugszeichen f der beiden Fig.
3 und 4 veranschaulicht die Profilgestaltung beim Variieren
an dieser Stelle. Der mittlere Abschnitt 40 bleibt bei der
Kernrippe stets aus vollem Material erhalten, unabhängig
davon ob die Rippe ausgehend von dem mittleren Teil 40 nach
unten (Fig. 4) oder nach oben (Fig. 3) ausgebildet ist.
Analog gilt dies auch für die Längsnuten im Schlüssel.A comparison, for example, of the ribs (or the analog ones
Grooves on the key) with the reference symbol f of the two FIGS.
3 and 4 illustrate the profile design when varying
at this point. The
Das Abtasten des erfindungsgemäßen Schlüssels erfolgt in einem Schloß, wie es prinzipiell von der Anmelderin bereits vorgeschlagen und beschrieben wurde. Die folgenden Fig. 5 bis 10 sollen die diesbezügliche Funktion nochmals erläutern.The key according to the invention is scanned in a lock, as already in principle by the applicant was proposed and described. The following Fig. 5 to 10 are said to function again explain.

kann er in den Schlüsselkanal eingeschoben werden, anderenfalls
ist das Einschieben verhindert. Die Kernrippen des
Schlüsselkanals überragen im Einschnittbereich die Mittellängsebene

Das Abtasten der Schrägprofilnuten 8 wird durch Sperrleisten
30 durchgeführt, wobei in bevorzugter Weise eine
Sperrleiste jeweils alle an einer Schlüsselflachseite vorgesehenen
Schrägprofilnuten oder -rippen 8 abtastet. Nur
wenn das Abtastende 31 mit den Schrägprofilnuten 8 der zugehörigen
Schlüsselflachseite zusammenpaßt, kann die Sperrleiste
30 nach innen in den Zylinderkern 24 geschoben
werden, sodaß das Rastende 32 den Eingriff mit der Rastausnehmung
33 freigibt, wonach der Zylinderkern 24 verdreht
werden kann.The scanning of the

voll erhalten bleiben muß. Es ist dies die Stelle
41 zwischen den jeweils zwei Gruppen von Schrägprofilnuten
(Fig. 1). Die Funktionsweise wird weiter unten beschrieben.
Durch den Kontrollstift, der an jeder der Sperrleisten vorgesehen
ist, wird verhindert, daß von einem mißbräuchlichen
Schlüsselnachahmer großflächig Schlüsselmaterial abgetragen
werden kann, um die Wirksamkeit der Abtastung durch die
Sperrleisten zu umgehen.The section through the locking
Fig. 6 zeigt einen Schnitt analog zu Fig. 5, wobei jedoch
in der linken Hälfte der Schlüssel eine Rippe 35 aufweist
und somit ein falscher Schlüssel ist. Diese Rippe 35 hindert
die Sperrleiste 30 daran, in den Zylinderkern einzutauchen.
Das Rastende 32 verhindert das Verdrehen des
Zylinderkerns.Fig. 6 shows a section analogous to Fig. 5, however

An der rechts eingezeichneten Stelle des Kontrollstiftes 34
weist der Schlüssel 1 kein Schlüsselmaterial auf, ist also
ein falscher Schlüssel, und die Konsequenz daraus wird in
der nachfolgenden Figur 7 dargestellt.At the location of
Bei dieser Fig. 7 ist beim Schloß und Schlüssel nach Fig. 6
der Zylinderkern so weit verdreht worden (was durch die
Freigabe der anderen Sperrelemente ermöglicht wurde), daß
der Abtastkopf 36 des Kontrollstifts 34 dem Gehäuseteil des
Zuhaltungsstiftes 27 gegenüberliegt. In diesem Bereich
weist der Zylinderkern eine Rastausnehmung 37 auf, in die
der Gehäusestift 27 unter dem Druck der Feder 28 eintaucht.
Er kann dies, weil der Kontrollstift an der Verschiebung
nicht gehindert wird, da das entsprechende Schlüsselmaterial
fehlt. Somit wird der Zylinderkern gefangen und
das Schloß blockiert.7 is in the lock and key of FIG. 6th
the cylinder core has been twisted so far (what by the
Release of the other locking elements was made possible) that

Durch etwas geänderte Ausbildung der Rastausnehmung 37 (mit Auflaufflächen) kann ermöglicht werden, daß der Schlüssel wieder in seine Ausgangslage zurückgedreht und wieder abgezogen werden kann.By changing the design of the recess 37 (with Treads) that can be made the key turned back to its starting position and removed again can be.

Die Sperrleiste 30 ist zu beiden Seiten des Schlüsselkanals
im Zylinderkern in entsprechenden Schlitzen 42 verschiebbar
gelagert (siehe Fig. 5). Dem Rastende 32 liegt das Abtastende
31 gegenüber. Dieses Abtastende 31 weist die
entsprechende Profilierung für die Schrägprofilnuten 8 des
Schlüssels auf. Eingezeichnet sind für die rechte Schrägprofilgruppe
fünf Nuten oder Rippen und für die linke
Schrägprofilgruppe vier Rippen und Nuten.The locking
In der Ausnehmung 43 sitzt verschiebbar der Kontrollstift

umfaßt. Der Führungsbolzen ist in der Bohrung 45 der Sperrleiste
30 gelagert, sodaß der Kontrollstift und dessen
Abtastkopf 36 verschiebbar ist. Die Funktionsweise ist den
