Description

Die Erfindung betrifft eine Schlüssel-Schlosskombination mit einem Flachschlüssel für Zylinderschlösser mit profiliertem senkrechtem Schlüsselkanal mit den Merkmalen des Patentanspruchs 1.The invention relates to a key-lock combination with a flat key for cylinder locks with profiled vertical key channel with the features of claim 1.

Aus dem deutschen Gebrauchsmuster 29718647.7 ist ein Flachschlüssel für Zylinderschlösser vorbekannt, der mit üblichen Verfahren nicht kopierfähig ist und welcher sich auf konventionelle Systeme von Zylinderschlössern mit profiliertem senkrechten Schlüsselkanal bezieht.From the German utility model 29718647.7 a flat key for cylinder locks is previously known, which is not copyable with conventional methods and which refers to conventional systems of cylinder locks with profiled vertical key channel.

Gemäß dieser bekannten Lehre weist der Flachschlüssel axial zum Schlüsselschaft symmetrische Einfräsungen entsprechend dem vorgegebenen Code auf. Anstelle einer Einfräsung ist dort eine vom Schließzylinder des Schlosses unabhängige, gebohrte Kerbe so angeordnet, dass diese zwischen den unsymmetrischen Profilnuten, die auf beiden Seiten des Schlüsselschaftes liegen, unterschiedliche Seitenwandhöhen aufweist.
Mit einer solchen Flachschlüsselausführung ist zwar im Vergleich bis zum dahin bekannt gewordenen Stand der Technik der Kopierschutz verbesserbar, jedoch besteht die Gefahr, dass mit nicht unerheblichem Fertigungsaufwand durch kombinierte Fräs-Bohreinrichtungen Nachschlüssel gefertigt werden können.According to this known teaching, the flat key axially symmetrical to the key shank milled in accordance with the predetermined code. Instead of a milled recess, a bored notch independent of the lock cylinder of the lock is arranged there so that it has different side wall heights between the asymmetrical profile grooves which lie on both sides of the key shank.
With such a flat key design, although the copy protection is improved compared to the prior art known there, but there is a risk that can be made with a significant manufacturing cost by combined milling drilling devices duplicate.

Aus der US 5,074,136 ist eine magnetische Schlossanordnung vorbekannt. Diese umfasst einen permanent magnetischen Schlüssel, einen rotierenden Zylinder mit einer Schlüsselöffnung und eine Gesamtheit von Öffnungen für je einen Schließpin mit einer Feder bzw. einen Permanentmagnet. In Verbindung damit ist ein röhrenförmiger Zylinder vorgesehen, der eine Gesamtheit von dazu gepaarten Öffnungen aufweist. Diese enthalten unterstützende Schließpins mit Federn. In einer Schließposition befinden sich die unterstützenden Schließpins zwischen dem rotierenden und dem röhrenförmigen Zylinder. Zum Entsperren wird der permanentmagnetische Schlüssel eingeführt. Dadurch werden die unterstützenden Schließpins und die Permanentmagnete in Richtung des röhrenförmigen bzw. des rotierenden Zylinders bewegt, wodurch das Schloss entsperrt wird und gedreht werden kann.From the US 5,074,136 is a magnetic lock arrangement previously known. This includes a permanent magnetic key, a rotating cylinder with a key opening and a set of openings for each a closing pin with a spring or a permanent magnet. In connection thus, there is provided a tubular cylinder having a total of paired openings. These contain supportive closing pins with springs. In a closed position, the supporting closing pins are between the rotating and the tubular cylinders. To unlock the permanent magnetic key is introduced. Thereby, the supporting closing pins and the permanent magnets are moved in the direction of the tubular and the rotating cylinder, whereby the lock is unlocked and can be rotated.

Aus dem Vorgenannten ist es daher Aufgabe der Erfindung eine weiterentwickelte Schlüssel-Schlosskombination mit einem kopiergeschützten Profil-Flachschlüssel für an sich bekannte Zylinderschlösser mit profiliertem senkrechten Schlüsselkanal anzugeben, wobei der Profil-Flachschlüssel durch mechanisches Bearbeiten aus einem Standard-Profil nicht zu einem schließfähigen Produkt führt.From the foregoing, it is therefore an object of the invention to provide an advanced key-lock combination with a copy-protected profile flat key for per se known cylinder locks with profiled vertical key channel, the profile flat key does not lead to a closable product by mechanical machining of a standard profile ,

Die Lösung der Aufgabe der Erfindung erfolgt mit einer Lehre gemäß den Merkmalen des Patentanspruchs 1. Der Unteranspruch enthält eine zweckmäßige Verwendung der erfindungsgemäßen Schlüssel-Schlosskombination.The solution of the object of the invention is achieved with a teaching according to the features of claim 1. The dependent claim includes an expedient use of the key-lock combination according to the invention.

Der Flachschlüssel der Schlüssel-Schlosskombination weist Einkerbungen und/oder Einfräsungen entsprechend einem vorgegebenen Code auf. Erfindungsgemäß ist im Profilbereich des Flachschlüssels ein permanent magnetischer Abschnitt, z.B. in Form eines magnetischen Stiftes oder eines magnetischen Plättchens eingesetzt und dort fixiert.The flat key of the key-lock combination has notches and / or milled in accordance with a predetermined code. According to the invention, in the profile area of the flat key a permanently magnetic section, e.g. used in the form of a magnetic pin or a magnetic plate and fixed there.

Erst nachdem der magnetische Abschnitt eingesetzt wurde, erfolgt erfindungsgemäß das an sich bekannte Ausbilden des Längsprofils des Flachschlüssels und der Kerben oder Fräsungen gemäß dem gewünschten Schlüsselcode.Only after the magnetic section has been used, according to the invention is the per se known forming of the longitudinal profile of the flat key and the notches or milling according to the desired key code.

Auf diese Weise ist der magnetische Abschnitt im Schlüsselmaterial eingebettet. Ein nachträgliches Einsetzen eines z.B. magnetischen Stiftes in einen Standardschlüssel ist nicht möglich.In this way, the magnetic portion is embedded in the key material. Subsequent insertion of eg a magnetic pen into a standard key is not possible.

Erfindungsgemäß ist die Lage des magnetischen Abschnittes auf der Längsachse des Schlüsselprofils derart gewählt, dass beim Ausbilden der für den Code notwendigen Kerben oder Fräsungen seitliche Stabilisierungs-Kerbflanken verbleiben und damit auf Dauer ein sicherer Halt des Magnetmaterials gewährleistet wird.According to the invention, the position of the magnetic section on the longitudinal axis of the key profile is selected such that when forming the notches or cuts necessary for the code, lateral stabilization notched flanks remain and thus a secure hold of the magnetic material is ensured in the long term.

Erfindungsgemäß sind weiterhin im Profilzylinder in entsprechenden Kernstiftbohrungen Kernstifte und im Profilzylinderboden Gehäusestifte untergebracht, wobei die Kernstifte von einer Stiftfeder unter Vorspannung gehalten sind.According to the invention further core pins are housed in the profile cylinder in corresponding core pin holes and housing pins in the profile cylinder base, wherein the core pins are held by a pin spring biased.

Der magnetische Abschnitt kann sich am tiefsten Punkt einer Kerbe befinden.The magnetic section may be at the lowest point of a notch.

Erfindungsgemäß ist bei der Schlüssel-Schlosskombination mit dem Flachschlüssel und dem zugehörigen Zylinderschloss mit profiliertem senkrechten Schlüsselkanal in mindestens einer zum magnetischen Abschnitt komplementären Bohrung für einen Kernstift ein ferromagnetischer Teilstift befindlich, dem sich mindestens ein zum Profilzylinderboden hinein erstreckender, nichtferromagnetischer weiterer Teilstift anschließt. Dabei ist unter der Wirkung des permanentmagnetischen Abschnittes eines eingeführten passenden Flachschlüssels der ferromagnetische Teilstift in eine Freigabeposition überführbar.According to the invention, a ferromagnetic partial pin is located in the key-lock combination with the flat key and the associated cylinder lock with profiled vertical keyway in at least one complementary magnetic portion for a core pin, which connects at least one non-ferromagnetic further part pin extending to the profile cylinder bottom. In this case, under the effect of the permanent magnetic portion of an inserted matching flat key, the ferromagnetic part pin can be transferred to a release position.

Zwischen diesen beiden Stiften liegt ein Freiraum dergestalt, dass einerseits im verschlossenen Zustand der ferromagnetische Teilstift in der jeweiligen Bohrung im Zylinder noch sicher aufgenommen ist und andererseits aber im entsperrten Zustand die Schließebene sicher freigegeben wird.Between these two pins is a free space such that on the one hand in the closed state of the ferromagnetic part pin is still securely received in the respective bore in the cylinder and on the other hand, the locking level is released safely in the unlocked state.

Erfindungsgemäß ist der Freiraum zwischen dem ferromagnetischen Teilstift und dem nicht ferromagnetischen Teilstift so gewählt, dass im verschlossenen Fall eine Schließebene durch den ferromagnetischen Teilstift blockiert ist und im entsperrten Zustand die Schließebene freigegeben wird.According to the invention, the clearance between the ferromagnetic part pin and the non-ferromagnetic part pin is chosen so that in the closed case a closing plane is blocked by the ferromagnetic part pin and in the unlocked state, the closing level is released.

Weiterhin kann zur Erhöhung der Anzahl möglicher Codierungen innerhalb einer Schließanlage der zusätzliche Einsatz eines Schließplättchens mit Magnetkern erfolgen.Furthermore, in order to increase the number of possible codings within a locking system, the additional use of a closing plate with magnetic core can take place.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispieles unter Zuhilfenahme von Figuren näher erläutert werden.The invention will be explained below with reference to an exemplary embodiment with the aid of figures.

In den zeichnerischen Darstellungen wird von einem an sich bekannten Profilzylinder mit senkrechtem Schlüsselkanal ausgegangen, der von einem Flachschlüssel betätigbar ist.In the drawings, it is assumed that a per se known profile cylinder with a vertical key channel, which is actuated by a flat key.

Im Profilzylinder sind in entsprechenden Bohrungen Kernstifte 1 untergebracht, die üblicherweise von einer Stiftfeder 4 unter Vorspannung gehalten werden. Weiterhin sind Gehäusestifte 3 vorhanden. An der Bodenseite des Profilzylinders sind Verschlussstifte 5 eingesetzt.In the profile cylinder core pins 1 are housed in corresponding holes, which are usually held by a pin spring 4 under tension. Furthermore, housing pins 3 are available. On the bottom side of the profile cylinder locking pins 5 are used.

Im Schlüssel befindet sich der magnetische Abschnitt 6, der mit einem Stahlstift 7 im Profilzylinder korrespondiert, wobei der Stahlstift 7 vom magnetischen Abschnitt 6 angezogen wird.In the key is the magnetic portion 6, which corresponds to a steel pin 7 in the profile cylinder, wherein the steel pin 7 is attracted by the magnetic portion 6.

Nichtferromagnetische weitere Teilstifte z.B. Messingstifte 8 können in unterschiedlicher Längenkombination vorliegen, um die gewünschte Anpassung an die Kerbtiefe im Schlüssel zu erreichen. Der Freiraum 9 zwischen Stahlstift 7 und den Messingstiften 8 ist so gewählt, dass im verschlossenen Fall die Schließebene 10 blockiert ist, andererseits aber mit Blick auf die Länge des Stahlstiftes eine Freigabe der Schließebene 10 dann gewährleistet wird, wenn der passende Schlüssel mit magnetischem Abschnitt 6 sich im zugehörigen Schloss befindet.Non-ferromagnetic further sub-pins e.g. Brass pins 8 can be available in different length combinations to achieve the desired adjustment to the notch depth in the key. The clearance 9 between the steel pin 7 and the brass pins 8 is selected so that in the closed case, the closing plane 10 is blocked, but on the other hand with respect to the length of the steel pin release of the closing level 10 is then ensured if the matching key with magnetic section. 6 is in the associated lock.

Die Darstellung nach Figur 2 zeigt, dass ein ansonsten identisch gekerbter bzw. gefräster Flachschlüssel nicht in der Lage ist einen Schließvorgang auszuführen, da der Stahlstift 7 sich in der Blockierposition befindet, d.h. nicht vom Magneten in die Freigabeposition überführt ist.The representation after FIG. 2 shows that an otherwise identically milled flat key is not able to perform a closing operation, since the steel pin 7 is in the blocking position, that is not transferred from the magnet to the release position.

Bei der Darstellung nach Figur 3 ist zusätzlich ein Schließplättchen mit Magnetkern 11 vorgesehen um die Anzahl möglicher Codierungen innerhalb einer Schließanlage zu erhöhen.In the presentation after FIG. 3 In addition, a closing plate with magnetic core 11 is provided in order to increase the number of possible codes within a locking system.

Die Erfindung ist für unterschiedlichste Schlüsselprofile anwendbar und kann in bestehende Anlagen integriert werden. Die Magnetlängen sind verschieden gewählt und berücksichtigen die Frästiefe. Durch die Auswahl geeigneter Kerbentiefen in Verbindung mit den jeweiligen Profilen lässt sich eine optimale Befestigung bzw. ein sicherer Halt der magnetischen Abschnitte auch über eine längere Einsatzdauer des Schlüssels sicherstellen.The invention is applicable to a variety of key profiles and can be integrated into existing systems. The magnet lengths are chosen differently and take into account the milling depth. By selecting suitable notch depths in connection with the respective profiles, an optimal fastening or a secure hold of the magnetic sections can also be ensured over a longer period of use of the key.
