Abstract

The lock and key combination has a cylindrical core turning in a housing, into which a flat key can be inserted. The key has profiled grooves and projections, with shaft height sensing taking place in a part length (6) of a profiled groove of which the base surface runs at an angle to the plane of the shaft, so that the plane of the angled base surface forms an acute angle with the plane in the extension of the opposite profile groove.

Description

Die Erfindung betrifft eine Schloss-Schlüsselkombination, mit einem im Schließzylindergehäuse drehbar angeordneten Zylinderkern, in den ein Flachschlüssel einführbar ist, der an den Seitenflächen in Längsrichtung des Schaftes verlaufende Profilierungen, bestehend aus parallel verlaufenden Profilnuten und - erhebungen, aufweist, wobei deren Höhe im Wesentlichen senkrecht zur Schaftlängsebene von mindestens einem Sperrstift abtastbar ist.The invention relates to a lock-key combination, with a cylinder core rotatably mounted in the lock cylinder housing into which a flat key can be inserted, which has profilings extending on the side surfaces in the longitudinal direction of the shaft, consisting of parallel profile grooves and elevations, the height of which is substantially perpendicular to the shaft longitudinal plane of at least one locking pin is scanned.

Die Profilierung von Schlüsseln besteht üblicherweise aus durchgehend in den Schlüsselschaft gefertigten Profilierungen. Im Schließzylinder enthält der Zylinderkern ein eingeräumtes Schlüsselprofil, welches zumindestens ein Schlüssel-, innerhalb von Schließanlagen auch verschiedene, unterschiedliche Schlüsselprofile aufnimmt. Die Profilierung im Schlüsselkanal ist normalerweise durchgängig von vorn bis hinten vorhanden.The profiling of keys usually consists of profilings made continuously in the key shank. In the lock cylinder of the cylinder core contains a granted key profile, which receives at least one key, within locking systems also different, different key profiles. The profiling in the keyway is usually continuous from front to back.

Die üblicherweise verwendeten Querschnitte yon Schlüssel-Profilschäften lassen insbesondere bei ausreichender Robustheit nur eine beschränkte Anzahl von unterschiedlichen Schlüsselprofilmerkmalen, also Codierungen an den Seitenflächen, zu.The usually used cross sections of key profile shafts allow, in particular with sufficient robustness, only a limited number of different key profile features, ie codes on the side surfaces.

Die Zahl der verschiedenen Profilmerkmale ist von Bedeutung für die Größe und die Komplexität der realisierbaren Schließanlagen. Wünschenswert ist auf jeden Fall die Erhöhung der Zahl der möglichen, auf einem Schlüssel bzw. im Schließzylinder realisierbaren Schlüssel- bzw. Schlüsselkanal-Profile.The number of different profile features is important for the size and complexity of the realizable locking systems. In any case, it is desirable to increase the number of possible key or keyway profiles that can be realized on a key or in the lock cylinder.

Schlüsselprofile haben unter dem Gesichtspunkt der Sicherheit, insbesondere der Abtastsicherheit von Schließzylindern und der Schlüsselsicberheit (Sicherheit von Schlüsseln gegen unbefugte handwerkliche oder gewerbliche Nachahmung) einen beschränkten Sicherheitswert, weil die Formgebung von außerhalb des Schließzylinders erkennbar und die unbefugte Anfertigung von Schlüsselrohlingen möglich istKey profiles have a limited safety value from the viewpoint of safety, in particular, the safety of scanning of lock cylinders and key security (security of keys against unauthorized craft or commercial imitation), because the shape from outside the lock cylinder recognizable and the unauthorized manufacture of key blanks is possible

Von außen heißt dabei, dass hier aufgrund der Gestaltung des von außen sichtbaren Teiles des Schlüsselkanals das Schlüsselprofil nachahmbar ist. Es ist theoretisch ohne weiteres möglich, beliebig oft zu einem Schließzylinder zu gehen, die Maße abzunehmen und in Ruhe den Rohling zu bearbeiten und jeweils wieder nachzubearbeiten, bis er paßt.From the outside, this means that the key profile can be imitated here due to the design of the externally visible part of the key channel. It is theoretically readily possible to go to a lock cylinder as often as you like, to take the measurements and to work on the blank in peace and to rework each time until it fits.

Eine Verschleierung des Schlüsselprofils also, die Nichterkennbarkeit von außerhalb, ist daher für die Erhöhung der Schlüsselsicherheit von großem Interesse.Obfuscation of the key profile, ie non-recognition from outside, is therefore of great interest for increasing key security.

Ein weiterer Bedarf zur Verbesserung der Schlüsselsicherheit besteht darin, das durchgängige Nacharbeiten von Schlüsselprofilen zu verhindern.Another need to improve key security is to prevent end-to-end reworking of key profiles.

Bei der Realisierung von Schließanlagen über Schlüsselprofile ist in der Schließanlagenhierarchie der am weitesten oben angesiedelte Schlüssel naturgemäß der dünnste. Je weiter der Schlüssel in der Hierarchiestufe über die Einzelprofile weiter hin zu den Zentralprofilen angesiedelt ist, um so dicker ist das Profil bzw. um so größer der Querschnitt.In the implementation of locking systems via key profiles, the key located at the top in the locking system hierarchy is naturally the thinnest. The farther the key is located in the hierarchy level over the individual profiles to the central profiles, the thicker is the profile or the larger the cross section.

In der Praxis ist der Mißbrauch zu beobachten, dass aus Schlüsseln mit großem Material- bzw. Profilquerschnitt ein übergeordnetes Profil durch mechanische Nacharbeit gefertigt wird, indem die beim übergeordneten Schlüssel nicht vorhandenen Profilmerkmale entfernt werden. Dies gelingt, da das Profil des übergeordneten in jedem Falle ein gemeinsames dünnstes aller in der Scbließanlage verwendeten Schlüsselprofile ist.
Bei einiger Kenntnis der Schloßanlagentechnologie kann so aus vorhandenen untergeordneten Profilen (Schlüsseln) ein übergeordnetes, ggf. durch mehrmaliges Probieren in anderen Schließzylindern, durch Nacharbeiten gefertigt werden. Das Schlüsselprofil wird dabei auf seiner gesamten Länge angepaßt,In practice, the abuse is observed that from keys with a large material or profile cross-section of a parent profile is made by mechanical rework by the profile features not present in the parent key are removed. This succeeds because the profile of the parent is in any case a common thinnest of all key profiles used in the scarfing system.
With some knowledge of the lock system technology can be made from existing subordinate profiles (keys) a parent, possibly by repeated testing in other lock cylinders, by rework. The key profile is adapted over its entire length,

Die Erfindung liegt die Aufgabe zugrunde, die Schlüsselsicherheit weiter zu erhöhen und unberechtigte Nachanfertigungen zu verhindern, zumindest aber sehr zu erschweren.The invention has for its object to further increase the key security and to prevent unauthorized reproductions, but at least greatly complicate.

Gelöst wird diese Aufgabe erfindungsgemäß mit einer Schloss-Schlüsselkombination, mit einem im Schließzylindergehäuse drehbar angeordneten Zylinderkern, in den ein Flachschlüssel einführbar ist, der an den Seitenflächen in Längsrichtung des Schaftes verlaufende Profilierungen, bestehend aus parallel verlaufenden Profilnuten und - erhebungen, aufweist, wobei deren Höhe im Wesentlichen senkrecht zur Schaftlängsebene von mindestens einem Sperrstift abtastbar ist, dadurch, dass mindestens eine Abtastung in einer Teillänge einer Profilnut erfolgt, deren Basisfläche derart schräg zur Schaftlängsebene verläuft, dass sich die Ebene der schrägen Basisflächen mit der Ebene in Verlängerung der gegenseitigen Profilnut unter einem spitzen Winkel trifft.This object is achieved according to the invention with a lock-key combination, with a lock cylinder housing rotatably mounted in the cylinder core, in which a flat key is inserted, extending on the side surfaces in the longitudinal direction of the shaft profilings consisting of parallel profile grooves and elevations, wherein the height thereof is scanned substantially perpendicular to the shaft longitudinal plane of at least one locking pin, characterized in that at least one scan in a partial length of a profile groove whose base surface is inclined to the shaft longitudinal plane, that the plane of the inclined base surfaces with the plane in extension of the mutual profile groove meets at an acute angle.

Nach einer vorzugsweisen Ausgestaltung ist die für die Abtastung vorgesehene Teillänge der Profilnut kürzer als die Gesamtlänge der entsprechenden Profilnut.According to a preferred embodiment, the partial length of the profiled groove intended for scanning is shorter than the total length of the corresponding profiled groove.

Es ist ferner vorteilhaft, wenn das Profil des Schlüssels im Abtastbereich des Sperrstiftes parazentrisch ausgebildet ist.It is also advantageous if the profile of the key is formed paracentrically in the scanning region of the locking pin.

Mit der erfindungsgemäßen Lösung wird einerseits erreicht, dass die konkrete Schlüsselprofilierung nicht an der Ausbildung des Schlüsselkanals im Zylinderkern erkennbar ist, weil die schräge Basisfläche nicht sichtbar ist. Ferner ist auch nicht erkennbar, wo die entsprechende Abtastung stattfindet, weil sich die besondere Profilgestaltung nicht über die gesamte Schaftlänge erstreckt.With the solution according to the invention, on the one hand, it is achieved that the specific key profiling can not be recognized by the formation of the key channel in the cylinder core, because the oblique base surface is not visible. Furthermore, it is not clear where the corresponding sampling takes place, because the particular profile design does not extend over the entire shaft length.

Andererseits würde die Herstellung eines sehr dünnen Schlüssels im Sinne der oben erwähnten Vorgehensweise dazu führen, dass der Schlüsselschaft so dünn wird, das ein Durchbrechen nicht verhindert werden kann.On the other hand, the production of a very thin key in the sense of the above-mentioned procedure would result in the key shank becoming so thin that break through can not be prevented.

Die Erfindung soll nachfolgend unter Bezug auf die Zeichnungen näher erläutert werden.The invention will be explained in more detail with reference to the drawings.

a detail

In der Figur 1 ist ein Teil des Schlüssels, und zwar des Schlüsselschaftes dargestellt und mit 1 bezeichnet.In the FIG. 1 is a part of the key, the key shaft represented and designated 1.

In der Schlüsselbrust 2 befinden sich die üblichen Kerben 3, die durch die Zuhaltungen abgetastet werden.
In dieser Figur 1 und in der Figur 2 sind die Profilnuten mit 4 und die Profilerhebungen mit 5 bezeichnet. Beides zusammen bildet die Profilierung der Seitenflächen des Schlüsselschaftes.
Über einen Teilabschnitt bzw. eine Teillänge 6 ist nun eine der Profilnuten in besonderer Weise ausgestaltet.
Diese Teillänge 6 ist mit einer schrägen Basisfläche 8 versehen, die in der linken Darstellung der Figur 2 und in der Figur 3 im Detail gezeigt ist.
Auf der gegenüberliegenden Seite des Schaftes 1 ist ebenfalls eine Profilnut 9 vorgesehen. In der Darstellung ist das Profil parazentrisch. Dies ist vorteilhaft, muss aber nicht sein. Wichtig ist nur die teilweise Schwächung des Profils dadurch, dass sich die Ebene 10 der schrägen Basisfläche 8 mit der Ebene 11 der Verlängerung der gegenseitigen Profilnut 9 unter einem spitzen Winkel trifft, wobei dieser außerhalb der Basisfläche der Profilnut 9 liegt, damit dort kein Loch entsteht.In the key breast 2 are the usual notches 3, which are scanned by the tumblers.
In this FIG. 1 and in the FIG. 2 are the profile grooves with 4 and the profile surveys designated 5. Both together form the profiling of the side surfaces of the key shank.
Over a partial section or a partial length 6, one of the profile grooves is now configured in a special way.
This part length 6 is provided with an inclined base surface 8, which in the left representation of FIG. 2 and in the FIG. 3 shown in detail.
On the opposite side of the shaft 1, a profile groove 9 is also provided. In the illustration, the profile is paracentric. This is beneficial but does not have to be. Important is only the partial weakening of the profile, characterized in that the plane 10 of the inclined base surface 8 with the plane 11 of the extension of the mutual profile 9 meets at an acute angle, which is outside the base surface of the profile 9, so there is no hole ,

Nicht dargestellt ist in den Figuren die Abtastung der Teillänge 6 mittels eines Sperrstiftes. Stimmen die Tiefe der Teilfläche 6 bzw. die Schräge der Teillänge 6 mit der Ausbildung des Sperrstiftes überein, so wird in üblicher Weise an der Trennlinie Zylinderkern/Zylindergehäuse ein Abgleich erreicht, so dass ein Schließvorgang ausführbar ist.Not shown in the figures, the scanning of the partial length 6 by means of a locking pin. If the depth of the partial surface 6 or the slope of the partial length 6 coincide with the design of the locking pin, an adjustment is achieved in the usual way on the dividing line cylinder core / cylinder housing, so that a closing operation can be carried out.

Die erfindungsgemäße Lösung bietet einerseits den Vorteil, dass die Lage und die Ausbildung der Teillänge 6 nicht von außen, also am Schlüsselkanal erkennbar ist.On the one hand, the solution according to the invention offers the advantage that the position and the formation of the partial length 6 can not be recognized from the outside, that is to say at the key channel.

Andererseits werden bei Nachanfertigungen von Schlüsseln die Profilausbildungen über die gesamte Schaftlänge gefräst. Im vorliegenden Fall würde dies zu einer so starken Schwächung des Schaftes führen, so dass ein Brechen entweder schon bei der Herstellung, spätestens aber bei der Benutzung des Schlüssels unvermeidbar ist.On the other hand, in the case of reproductions of keys, the profile formations are milled over the entire shaft length. In the present case, this would lead to such a strong weakening of the shaft, so that breaking is inevitable either already during manufacture, but at the latest when using the key.
