Description

Die Erfindung betrifft ein Zylinderschloss mit Zylinderkern und Gehäuse, in dem federbelastete Zuhaltestifte, umfassend Gehäusestifte und Zylinderkernstifte, zum Abfragen von am Schlüssel befindlichen Einschnittfräsungen vorgesehen sind. Des weiteren betrifft die Erfindung einen Flachschlüssel für ein Zylinderschloss, wobei der Flachschlüssel vorzugsweise als Wendeschlüssel mit zwei Schlüsselflachseiten und zwei Schlüsselschmalseiten ausgebildet ist, und wobei der Flachschlüssel unterschiedlich tiefe Einschnittfräsungen an zumindest einer Schlüsselschmalseite, bevorzugt an zwei Schlüsselschmalseiten und gegebenenfalls weitere Steuerflächen, Einkerbungen oder Steuerbahnen an den Schlüsselflachseiten aufweist.The invention relates to a cylinder lock with cylinder core and housing in which spring-loaded tumbler pins, comprising housing pins and cylinder core pins, are provided for interrogating cutting incisions on the key. Furthermore, the invention relates to a flat key for a cylinder lock, wherein the flat key is preferably formed as a reversible key with two key flat sides and two key narrow sides, and wherein the flat key of different depth Einschnittfräsungen on at least one key narrow side, preferably on two key narrow sides and optionally further control surfaces, notches or control tracks has at the key flat sides.

Bekannt sind Zylinderschlösser, die unterschiedliche Einschnittfräsungen oder Profilnuten abtasten. Eine Erhöhung der Variationsmöglichkeiten der Einschnittfräsungen oder Profilnuten am Schlüssel führt jedoch im Normalfall dazu, dass die Konstruktion der Schlösser immer aufwendiger wird, was sowohl nachteilig für die Funktionssicherheit der Schlösser ist, als auch zu höheren Produktionskosten führt.Cylinder locks are known which scan different incision grooves or profile grooves. Increasing the possibilities of variation of the incision grooves or profile grooves on the key, however, normally leads to the construction of the locks becoming more and more complicated, which is both disadvantageous for the functional reliability of the locks and also leads to higher production costs.

Auch bei den Schlüsseln birgt die Erhöhung der Variationsmöglichkeit meist Nachteile, wie zB einen erhöhten Herstellungsaufwand durch die Verwendung verschiedener Fräsmaschinen bzw der Bearbeitung des Rohlings in mehreren Schritten auf unterschiedlichen Maschinen, wodurch auch hier die Kosten für den einzelnen Schlüssel wesentlich höher ausfallen.Even with the keys, the increase in the possibility of variation usually involves disadvantages, such as increased production costs due to the use of different milling machines or the processing of the blank in several steps on different machines, whereby the costs for the individual keys are also significantly higher.

Es ist somit Aufgabe der Erfindung ein Schloss zu schaffen, das höhere Variationsmöglichkeiten bei der Kodierung der Schlüssel zulässt, wobei gleichzeitig die Konstruktion des Schlosses einfach gehalten wird, wodurch erhöhte Funktionssicherheit gegeben ist sowie die Herstellungskosten gering gehalten werden. Ferner ist es Aufgabe der Erfindung einen Schlüssel zu schaffen, der ebenfalls erhöhte Variationsmöglichkeiten bietet, dabei aber gleichzeitig einfach und billig herzustellen ist und eine hohe Schließsicherheit aufweist.It is therefore an object of the invention to provide a lock that allows higher possibilities of variation in the coding of the keys, at the same time the construction of the castle is kept simple, whereby increased reliability is given and the manufacturing costs are kept low. It is another object of the invention to provide a key that also offers increased possibilities for variation, but at the same time is easy and cheap to manufacture and has a high security lock.

Dies wird bei einem erfindungsgemäßen Zylinderschloss dadurch erreicht, dass die Zylinderkernstifte an dem in den Schlüsselkanal ragenden Ende als Abtastfortsätze ausgebildet sind, die schmäler als der Durchmesser des Zylinderkernstifts sind und in Längsrichtung des Schlüsselkanals ausgerichtet sind, wobei zumindest zwei Zylinderkernstifte voneinander unterschiedliche entweder mittig entlang der Längsmittelebene des Schlüsselkanals oder links oder rechts parallel versetzt dazu angeordnete Abtastfortsätze aufweisen.This is achieved in a cylinder lock according to the invention characterized in that the cylinder core pins are formed at the projecting into the keyway end as Abtastfortsätze which are narrower than the diameter of the cylinder core pin and in Longitudinal direction of the keyway are aligned, wherein at least two cylinder core pins have different from each other either centrally along the longitudinal center plane of the keyway or left or right offset parallel thereto arranged Abtastfortsätze.

Die Abtastfortsätze können als Stege ausgebildet sein, die in unterschiedlichem Normalabstand, parallel zur Längsmittelebene oder mittig entlang der Längsmittelebene anordbar sind. Durch die unterschiedliche Anordnung der Abtastfortsätze wird die Variationszahl des Schlosses wesentlich erhöht, da nicht nur unterschiedliche tiefe Einschnittfräsungen abfragbar sind, sondern auch mehrere verschiedene Normalabstände zur Längsmittelebene möglich sind. Dabei bleibt die Konstruktion des Schlosses weiterhin einfach, da gegenüber einem herkömmlichen Zylinderschloss mit geteilten Zuhaltestiften lediglich die Zylinderkernstifte abgewandelt sind.The Abtastfortsätze may be formed as webs, which can be arranged in different normal distance, parallel to the longitudinal center plane or centrally along the longitudinal center plane. Due to the different arrangement of the Abtastfortsätze the variation number of the lock is substantially increased, since not only different deep Einschnittfräsungen be interrogated, but also several different normal distances to the longitudinal center plane are possible. The construction of the lock remains simple, since compared to a conventional cylinder lock with split tumbler pins, only the cylinder core pins are modified.

Ein weiteres Merkmal der Erfindung ist es, dass die Abtastfortsätze die gleiche Breite aufweisen oder unterschiedliche Breiten aufweisen. Durch die Variation der Breiten kann die Zahl der Variationsmöglichkeiten des Zylinderschlosses weiter erhöht werden.Another feature of the invention is that the Abtastfortsätze have the same width or have different widths. By varying the widths, the number of possible variations of the cylinder lock can be further increased.

Ferner ist es ein Merkmal der Erfindung, dass die Zylinderkernstifte seitliche Fortsätze aufweisen, welche in entsprechenden Nuten im Zylinderkern angeordnet sind, wodurch das Verdrehen der Zylinderkernstifte verhindert ist.Further, it is a feature of the invention that the cylinder core pins have lateral projections which are arranged in corresponding grooves in the cylinder core, whereby the rotation of the cylinder core pins is prevented.

Weiters wird die Aufgabe für einen erfindungsgemäßen Flachschlüssel dadurch gelöst, dass die Einschnittfräsungen am Flachschlüssel schmäler als die Schlüsselschmalseite sind, und dass zumindest zwei Einschnittfräsungen voneinander unterschiedlich entweder mittig entlang der Längsmittelebene des Schlüssels oder links oder rechts parallel versetzt dazu angeordnet sind.Furthermore, the object is achieved for a flat key according to the invention in that the incision grooves on the flat key are narrower than the key narrow side, and that at least two incision milled from each other either centrally along the median longitudinal plane of the key or left or right offset parallel thereto.

Zumindest eine der Einschnittfräsungen kann von zwei Rippen verbleibenden Schlüsselmaterials seitlich verdeckt sein, was die Nachmachbarkeit des Schlüssels erschwert. Ferner ist es ein Merkmal, dass zumindest eine Einschnittfräsung an einem Rand der Schlüsselschmalseite angeordnet ist.At least one of the cutting grooves can be concealed laterally by two ribs remaining key material, which complicates the Nachmachbarkeit the key. Furthermore, it is a feature that at least one incision groove is arranged on an edge of the narrow side of the key.

Um eine hohe Variationszahl sowie eine hohe Sperrsicherheit zu gewährleisten ist es ein weiteres Merkmal, dass zumindest drei, vorzugsweise fünf voneinander in ihrem Normalabstand zur Längsmittelebene unterschiedliche, gegebenenfalls sich überschneidende Einschnittfräsungen vorgesehen sind.In order to ensure a high number of variations as well as a high blocking security, it is a further feature that at least three, preferably five, of each other in their Normal distance to the longitudinal center plane different, possibly overlapping incision Mills are provided.

Die Einschnittfräsungen können eine Steuerfläche in Form eines Kreisbogenabschnittes aufweisen, wobei es ein weiteres Merkmal sein kann, dass die Kreisbogenabschnitte der Einschnittfräsungen alle den gleichen Radius aufweisen. Es ist somit möglich den Schlüssel durch den Einsatz eines Rundfräsers mit gleichbleibendem Fräsradius möglichst schnell und kostengünstig zu fertigen.The incision mills may have a control surface in the form of a circular arc section, wherein it may be a further feature that the circular arc sections of the incision mills all have the same radius. It is thus possible to produce the key as quickly and inexpensively as possible by using a round milling cutter with the same cutting radius.

Des weiteren können entlang der Schlüsselflachseiten Längsprofilnuten vorgesehen sein, wobei als weiteres Merkmal zumindest zwei der Längsprofilnuten auf den gegenüber-liegenden Schlüsselflachseiten überlappend angeordnet sein können. Das bedeutet, dass die Längsprofilnuten in ihrer Tiefe zumindest bis zur Längsmittelebene des Schlüssels heranreichen oder sogar über diese hinausgehen.Furthermore, along the key flat sides Längsprofilnuten be provided, wherein as a further feature at least two of the Längsprofilnuten may be arranged overlapping on the opposing key flat sides. This means that the Längsprofilnuten reach in depth, at least to the longitudinal median plane of the key or even go beyond this.

Weitere Merkmale sind den Ansprüchen, der Beschreibung sowie den beiliegenden Zeichnungen zu entnehmen.Further features can be found in the claims, the description and the accompanying drawings.

Der in Fig. 1 gezeigte Flachschlüssel 1 besitzt einen Schlüsselgriff 2 sowie einen Schlüsselschaft mit zwei Schlüsselflachseiten 4 und zwei Schlüsselschmalseiten 3. Angeordnet an den Schlüssel 1 sind Zylinderkernstifte 7 des Zylinderschlosses gezeigt, welche mit ihren Abtastfortsätzen 9 die Einschnittfräsungen 6 an der Schlüsselschmalseite 3 abtasten. Der Einfachheit halber sind die übrigen Schlossteile, wie Gehäuse, Zylinderkern mit Schlüsselkanal und Kernbohrungen, sowie die Gehäusestifte und Federn nicht gezeigt. Damit die parallel zur Längsrichtung ausgerichteten Abtastfortsätze 9 der Zylinderkernstifte 7 in den entsprechenden Kernbohrungen nicht verdreht werden können, sind seitliche Fortsätze 8 vorgesehen, welche in entsprechenden Nuten im Zylinderkern 10 angeordnet sind.The flat key 1 shown in Fig. 1 has a key handle 2 and a key shank with two key flat sides 4 and two key narrow sides 3. Arranged on the key 1 cylinder core pins 7 of the cylinder lock are shown, which scan the Einschnittfräsungen 6 on the key narrow side 3 with their Abtastfortsätzen 9. For simplicity, the other lock parts, such as housing, cylinder core with keyway and core holes, and the housing pins and springs are not shown. Thus, the aligned parallel to the longitudinal direction Abtastfortsätze 9 of the cylinder core pins 7 in the corresponding core holes not twisted can be, lateral extensions 8 are provided, which are arranged in corresponding grooves in the cylinder core 10.

Fig. 2 zeigt einen Querschnitt durch einen erfindungsgemäßen Flachschlüssel 1 sowie einen schematischen Detailquerschnitt durch einen Zylinder 10 eines erfindungsgemäßen Zylinderschlosses. Das umliegende Gehäuse ist zur einfacheren Darstellung nicht gezeigt. Die an den Schlüsselschmalseiten 3 angeordneten Einschnittfräsungen 6 weisen kreisbogenförmige Steuerflächen 11 auf. An den Schlüsselflachseiten 4 sind Längsprofilnuten 5 angeordnet, von denen wie in Fig. 2 gezeigt zumindest zwei überlappend angeordnet sind.2 shows a cross section through a flat key 1 according to the invention and a schematic detail cross section through a cylinder 10 of a cylinder lock according to the invention. The surrounding housing is not shown for ease of illustration. The incision cuts 6 arranged on the key narrow sides 3 have arcuate control surfaces 11. On the key flat sides 4 are arranged longitudinal profile grooves 5, of which at least two are arranged overlapping, as shown in FIG.

Fig. 3 zeigt mögliche Ausführungsformen für Zylinderkernstifte 7 eines erfindungsgemäßen Zylinderschlosses in einer Aufsicht. Wie in dieser Figur gezeigt können die Abtastfortsätze 9 auch als Stege 12 mit gleicher oder unterschiedlicher Breite ausgebildet sein. Die hier als Stege 12 ausgebildeten Abtastfortsätze weisen alle die gleiche Breite auf, die randseitigen Abtastfortsätze 9 sind in diesem Ausführungsbeispiel breiter angeordnet. Die seitlichen Fortsätze 8, die im Zylinderkern in entsprechenden Nuten angeordnet sind verhindern, dass sich die Zylinderkernstifte 7 in den entsprechenden Kernbohrungen verdrehen können. Bei dem gezeigten Beispiel werden drei verschiedene Zylinderkernstifte 7 hergestellt. Sie weisen entweder einen mittig entlang der Längsmittelebene angeordneten Steg 12, einen in einem ersten Normalabstand zur Längsmittelebene seitlich versetzten Steg oder einen randseitig angeordneten Abtastfortsatz 9 auf. Die Stifte mit seitlich versetztem Steg 12 oder mit randseitigem Abtastfortsatz 9 können in zwei verschiedenen Ausrichtungen in die Zylinderkernbohrungen eingebracht werden, wodurch sich fünf verschiedene Möglichkeiten zur Abtastung seitlich versetzter Einschnittfräsungen ergeben.Fig. 3 shows possible embodiments for cylinder core pins 7 of a cylinder lock according to the invention in a plan view. As shown in this figure, the Abtastfortsätze 9 may also be formed as webs 12 with the same or different width. The scanning extensions formed here as webs 12 all have the same width, the edge-side scanning extensions 9 are arranged wider in this embodiment. The lateral extensions 8, which are arranged in the cylinder core in corresponding grooves prevent the cylinder core pins 7 can rotate in the corresponding core holes. In the example shown, three different cylinder core pins 7 are made. They either have a web 12 arranged centrally along the longitudinal center plane, a web laterally offset at a first normal distance from the longitudinal center plane, or a scanning extension 9 arranged at the edge. The pins with laterally offset web 12 or edge-side Abtastfortsatz 9 can be introduced in two different orientations in the cylinder core holes, resulting in five different ways to scan laterally offset cutting cuts.

Die Breite der Stege 12 oder der Abtastfortsätze 9 kann auch unterschiedlich breit gewählt werden, wodurch eine weitere Erhöhung der Variationszahl möglich ist. In der in den Figuren 3 und 4 gezeigten Ausführungsformen ist der randseitige Abtastfortsatz 9 breiter ausgebildet als die Stege 12, was jedoch für die entsprechende Breite der Einschnittfräsung 6 in diesem Fall keine Rolle spielt, da die entsprechenden Einschnittfräsungen 6 ebenfalls am Rand der Schlüsselflachseite 3 angeordnet sind und somit zur jeweiligen Schlüsselflachseite 4 hin offen sind.The width of the webs 12 or the Abtastfortsätze 9 can also be chosen different widths, whereby a further increase in the number of variations is possible. In the embodiments shown in Figures 3 and 4, the edge-side Abtastfortsatz 9 is wider than the webs 12, but this is irrelevant for the corresponding width of the cut groove 6 in this case, since the corresponding incision grooves 6 also arranged at the edge of the key flat side 3 are and are therefore open to the respective key flat 4.

Die Figuren 5 und 6 zeigen eine Detailansicht eines erfindungsgemäßen Flachschlüssels in einer Seitenansicht und einer Aufsicht. Wie in Fig. 5 dargestellt weisen die Einschnittfräsungen 6 eine kreisbogenförmige Steuerfläche 11 auf. Strichliert eingezeichnet sind andere mögliche Steuerflächen 11 für die unterschiedlichen Tiefen der Einschnittfräsungen 6 gezeigt. All diese Steuerflächen 11 weisen den gleichen Radius auf, wodurch sie einfach mit dem gleichen Rundfräser herstellbar sind.Figures 5 and 6 show a detailed view of a flat key according to the invention in a side view and a top view. As shown in FIG. 5, the incision grooves 6 have a circular-arc-shaped control surface 11. Dashed lines show other possible control surfaces 11 for the different depths of the incision grooves 6. All of these control surfaces 11 have the same radius, which makes them easy to produce with the same round cutter.

Fig. 6 zeigt den Schlüssel aus Fig. 5 in einer Aufsicht, wobei die unterschiedlichen seitlichen Anordnungen der Einschnittfräsungen 6 ersichtlich sind. Die Einschnittfräsungen 6 können entweder zu beiden Seiten hin von Stegen aus verbleibenden Schlüsselmaterial verdeckt sein, was die Nachmachbarkeit des Schlüssels erschwert und scharfe Kanten an den Schlüsselschmalseiten, die zu Verletzungen führen könnten, vermindert, oder am Rand einer Schlüsselschmalseite angeordnet sein. Des weiteren können sich einzelne Einschnittfräsungen 6 an jenen Positionen, die nicht durch die Abtastfortsätze 9 abgefragt werden überschneiden, was ebenfalls zu einer erschwerten Nachmachbarkeit des Schlüssels führt.FIG. 6 shows the key from FIG. 5 in a plan view, wherein the different lateral arrangements of the incision grooves 6 can be seen. The cut grooves 6 can either be concealed on both sides by webs of remaining key material, which complicates the Nachmachbarkeit of the key and sharp edges on the key narrow sides, which could lead to injury, reduced, or arranged on the edge of a key narrow side. Furthermore, individual incision grooves 6 can overlap at those positions that are not interrogated by the scanning extensions 9, which also leads to a difficult imitation of the key.
