Definitions
- the invention relates to a lock cylinder or a flat key for a lock cylinder, with a cylinder core rotatable in a bore in a cylinder housing with a key channel, and with radially arranged, spring-loaded, displaceable core and housing pins which act as tumblers from notches or toothings of the flat key a blocking position blocking the rotation of the cylinder core in the cylinder housing can be displaced into a release position.
- a suitable flat key arranges the tumblers consisting of core and housing pins in such a way that the abutting surface between the core and housing pins comes to rest in the outer surface of the cylinder core.
- the cylinder core can then be rotated in the cylinder housing. This rotation is transmitted via a locking lug to a lock (mortise lock, mortise lock, box bolt lock or the like) which pushes out or pulls out one or more bolts.
- electrical switches e.g. alarm systems are often operated in this way.
- the invention aims to improve a lock cylinder with regard to night-time security without great design effort, which could lead to a susceptibility to malfunctions, and to provide a key that has characteristic features that cannot be supplemented by subsequent machining of a serial key.
- This is achieved in that the core pin initially lying at the opening of the key channel, in its part projecting into the key channel and the flat key next to the notch or toothing assigned to the core pin, has a mutual positive connection for fixing the position of the core pin when the key is inserted, and in that At least one recess is provided in the cylinder housing through the cross-sectional plane, the opening of which opens into the bore for the cylinder core, the recess being designed for immersing the core pin and having the stop surface for blocking the further rotation of the cylinder core in the cylinder housing.
- the core pin When the locking cylinder is actuated by an ordinary serial key, after the cylinder core has been turned away from the locked position, the core pin immediately falls into the recess in the cylinder housing and blocks further rotation. Only with a flat key, which also holds the core pin positively in addition to its radial positioning, remains fixed in position even when the cylinder core is rotated, so that the core pin slides over the recess in the cylinder housing without being immersed in it. It is expedient if the core pin has an annular groove as a positive connection and the flat key has a flank engaging in this in the region of the notch or toothing displacing the core pin.
- the flank can be designed as a hook-like projection, the distance of the annular groove from the head of the core pin corresponding to the distance of the control surface of the key notch or the toothing from the projecting flank, that is to say the hook nose of the form-locking element provided on the key.
- the core pin is a steel pin, as is known, and a magnet is provided in the recess.
- a force is exerted on the core pin in the rotational position of the cylinder core as soon as the position of the core pin is aligned with the recess in the cylinder housing in the radial direction.
- the recess or one or more additional recesses in the cylinder housing can be provided in the rotational plane of the core pin.
- the recess has an entry slope in the direction of rotation of the cylinder core.
- the flat key has a special feature. It is characterized in that the notch or toothing, for the first core pin of a locking cylinder, is assigned a flank projecting into a key channel in the direction of insertion of the key. In an advantageous embodiment, the flank is formed as part of a hook-shaped tooth which is arranged between the key chalk and the first notch or toothing and extends over the control surface of the notch or toothing.
- a key blank is characterized in that a flank projecting into the key channel and holding the first core pin, in the direction of insertion of the key into the key channel, in particular a hook, is provided next to the key cord.
- Fig. 1 shows a longitudinal section through part of a locking cylinder with a matching flat key
- Fig. 2 shows a cross section along the line 11-11 in Fig. 1 with the flat key removed.
- a cylinder core 1 is rotatably supported in a cylinder housing 2.
- core pins 4 and housing pins 5 are each displaceable against spring force.
- a flat key 6 engages in a key channel 7 of the cylinder core and has notches or serrations 8 in the beard area, the control surfaces of which shift the core pins 4 together with the housing pins 5.
- the "correct" key shown in FIG. 1 causes a shift in which the contact surfaces between the core pins 4 and the housing pins 5 lie exactly in the dividing surface between the cylinder core 1 and the cylinder housing 2. As a result, the cylinder core 1 can be rotated in the cylinder housing 2.
- the core pin 4 'initially located at the entrance of the key channel 7 has in its part projecting into the key channel 7 an annular groove 9 as a form-locking element with respect to the key 6, which in the area of its control surface assigned to the said core pin 4' overlaps a flank 10 projecting in the direction of insertion Has the shape of a hook-like projection as a form-locking element, which cooperates with those of the core pin 4 '.
- the vertical distance of the annular groove 9 from the head of the core pin 4 ' is equal to the vertical distance between the control surface of the key 6 and the flank 10.

- the cylinder housing 2 In the area of rotation of the core pin 4 '(drawing plane of FIG. 2) there is a recess 11 in the cylinder housing 2 which is open towards the cylinder core 1.
- the recess 11 is dimensioned so that the core pin 4 'can dip into it, should it not be held as shown in FIG. 1. This occurs when a key 6 is equipped with the appropriate notches or serrations 8 for the correct positioning of the core and housing pins 4, 5 acting as tumblers, but no additional positive connection (eg flank 10, annular groove 9) to the core pin 4 '.
- the cylinder core 1 can then be turned slightly out of the locked position; the core pin 4 'lying loosely in its bore, however, immediately falls into the recess 11 and blocks the further core rotation, unless it is held in the core according to the invention.
- the recess 11 has an inlet slope 12 and a stop surface 13 for the core pin 4 '.
- the core pin 4 ' is made of steel. It is drawn into the recess 11.
- the bevel 12 is provided so that the cylinder core 1 can be turned back into the starting position. Along this, the core pin 4 'is pushed back into the position shown in FIG. 1.
- the "wrong" key can also be removed.
- the recess can be provided to the left and / or to the right of the housing pin 5 '.
- An additional recess 11 ' can also be arranged approximately diametrically to the recess 11, which comes into effect when the locking cylinder is mounted rotated by 180 ° in the unusual installation position.
- the key 6 can not be made from a conventional blank due to the edge 10. Because of the undercut that delimits the flank 10, it is also not possible to use the usual milling tools that are used for the production of duplicate keys. However, a blank can be manufactured by the lock manufacturer in such a way that the flank 10 is already present with an otherwise notchless key. The radial distance of the annular groove 9 in the core pin 4 'from the axis of rotation of the cylinder core 1 is then constant for this series of blanks, while the total length of the corresponding core pins can vary from blocking area to blocking area depending on the position of the control surface of the first notch.
- the head region of the core pin 4 ' can also be frustoconical, the base surface of the truncated cone representing the head surface of the core pin 4'.
- the flank of the key then has a slope that is matched to the cone angle.
- the tooth-like flank 10 according to FIG. 1 can also overlap the core pin 4 'in a U-shape.
- the flank 10 can furthermore have an end edge which runs obliquely to the insertion direction of the key and which engages laterally tangentially on the core pin 4 'in a form-fitting manner.

Abstract
Description
Die Erfindung betrifft einen Schließzylinder bzw. einen Flachschlüssel für einen Schließzylinder, mit einem in einer Bohrung eines Zylindergehäuses drehbaren Zylinderkern mit Schlüsselkanal, sowie mit unter Federvorspannung stehenden radial angeordneten, verschiebbaren Kern- und Gehäusestiften, die als Zuhaltungen von Kerben bzw. Zahnungen des Flachschlüssels aus einer die Drehung des Zylinderkernes im Zylindergehäuse blockierenden Sperrstellung in eine Freigabestellung verschiebbar sind.The invention relates to a lock cylinder or a flat key for a lock cylinder, with a cylinder core rotatable in a bore in a cylinder housing with a key channel, and with radially arranged, spring-loaded, displaceable core and housing pins which act as tumblers from notches or toothings of the flat key a blocking position blocking the rotation of the cylinder core in the cylinder housing can be displaced into a release position.
Bei den heute weltweit verbreiteten Schließzylindern ordnet ein passender Flachschlüssel die aus Kern- und Gehäusestiften bestehenden Zuhaltungen derart, daß die Stoßfläche zwischen den Kern- und Gehäusestiften in der Mantelfläche des Zylinderkernes zu liegen kommt. Es läßt sich dann der Zylinderkern im Zylindergehäuse drehen. Diese Drehung wird über eine Sperrnase an ein Schloß (Einstemmschloß, Einsteckschloß, Kastenriegelschloß od.dgl.) übertragen, welches einen oder mehrere Riegel ausschiebt oder zurückzieht. Auch elektrische Schalter,z.B. von Alarmanlagen,werden oftmals auf diese Weise betätigt.In the locking cylinders that are widespread worldwide today, a suitable flat key arranges the tumblers consisting of core and housing pins in such a way that the abutting surface between the core and housing pins comes to rest in the outer surface of the cylinder core. The cylinder core can then be rotated in the cylinder housing. This rotation is transmitted via a locking lug to a lock (mortise lock, mortise lock, box bolt lock or the like) which pushes out or pulls out one or more bolts. Also electrical switches, e.g. alarm systems are often operated in this way.
Im Zuge der Weiterentwicklung dieses seit Jahrzehnten bekannten und erprobten Sperrprinzips war man bestrebt, zusätzliche Sicherheitskriterien zu überlagern. In diesem Sinn ist es bekannt, den Flachschlüssel mit seitlichen Steuerrippen auszustatten, die axiale Stifte gegen Federkraft verschieben um im Zusammenwirken mit Sperrkörpern, wie etwa Kugeln, eine zusätzliche Blockierung oder Freigabe des Zylinderkernes zu bewirken. Es sind auch radial im Zylinderkern frei verschiebbare Einlegestifte in Kernbohrungen bekannt, die mit Ausnehmungen in der Flachseite des Schlüssels zusammenarbeiten. Diese Stifte greifen in Ausnehmungen des Zylindergehäuses ein und können bei einer Drehung nur dann in den Zylinderkern zurückweichen,wenn eine entsprechende Ausnehmung am Schlüssel vorhanden ist.In the course of the further development of this locking principle, which has been known and tested for decades, efforts were made to superimpose additional security criteria. In this sense, it is known to equip the flat key with lateral control ribs that move axial pins against spring force in order to effect an additional blocking or release of the cylinder core in cooperation with locking bodies, such as balls. There are also known radially displaceable insert pins in core bores in the cylinder core, which cooperate with recesses in the flat side of the key. These pins engage in recesses in the cylinder housing and can only move back into the cylinder core when they are rotated if there is a corresponding recess on the key.
Die Erfindung zielt darauf ab, ohne großen konstruktiven Aufwand, der zu einer Störungsanfälligkeit führen könnte, einen Schließzylinder hinsichtlich der Nachtsperrsicherheit zu verbessern und einen Schlüssel vorzusehen, der charakteristische Merkmale aufweist, die durch nachträgliche spanabhebende Bearbeitung eines Serienschlüssels nicht ergänzt werden können. Dies wird dadurch erreicht, daß der der Öffnung des Schlüsselkanals zunächst liegende Kernstift in seinem in den Schlüsselkanal hineinragenden Teil und der Flachschlüssel nächst der dem Kernstift zugeordneten Kerbe oder der Zahnung eine gegenseitige formschlüssige Verbindung zur Lagefixierung des Kernstiftes bei eingeschobenem Schlüssel aufweist und daß in der den Kern durchsetzenden Querschnittsebene mindestens eine Ausnehmung im Zylindergehäuse vorgesehen ist, deren Öffnung in die Bohrung für den Zylinderkern einmündet, wobei die Ausnehmung zum Eintauchen des Kernstiftes ausgebildet ist und die Anschlagfläche zur Blockierung derweiteren Drehung des Zylinderkernes im Zylindergehäuse aufweist. Der Kernstift fällt bei Betätigung des Schließzylinders durch einen gewöhnlichen Serienschlüssel nach dem Wegdrehen des Zylinderkernes aus der Sperrstellung sofort in die Ausnehmung im Zylindergehäuse und blockiert die weitere Drehung. Nur mit einem Flachschlüssel, der den Kernstift zusätzlich zu seiner radialen Positionierung auch noch formschlüssig festhält, bleibt auch bei der Drehung des Zylinderkernes innerhalb des Kernmantels lagefixiert, sodaß der Kernstift über die Ausnehmung im Zylindergehäuse hinweggleitet, ohne in diese einzutauchen. Es ist zweckmäßig, wenn der Kernstift als formschlüssige Verbindung eine Ringnut und der Flachschlüssel eine in diese eingreifende Flanke im Bereich der den Kernstift verschiebenden Kerbe bzw. Zahnung aufweist. Die Flanke kann als hakenartiger Vorsprung ausgebildet sein, wobei der Abstand der Ringnut vom Kopf des Kernstiftes dem Abstand der Steuerfläche der Schlüsselkerbe oder der Zahnung von der vorspringenden Flanke, also der Hakennase des am Schlüssel vorgesehenen Formschließelementes entspricht. Zur Unterstützung des Effektes ist es zweckmäßig, wenn der Kernstift wie bekannt ein Stahlstift ist und in der Ausnehmung ein Magnet vorgesehen ist. Dadurch wird auf den Kernstift in der Drehstellung des Zylinderkerns eine Kraft ausgeübt, sobald die Lage des Kernstiftes in radialer Richtung mit der Ausnehmung im Zylindergehäuse fluchtet. Um eine sichere Funktion auch in Einbaulagen des Schließzylinders zu gewährleisten, die nicht der üblichen Einbaulage entsprechen, kann die Ausnehmung bzw. könne eine oder mehrere zusätzliche Ausnehmungen im Zylindergehäuse in der Drehebene des Kernstiftes vorgesehen sein.The invention aims to improve a lock cylinder with regard to night-time security without great design effort, which could lead to a susceptibility to malfunctions, and to provide a key that has characteristic features that cannot be supplemented by subsequent machining of a serial key. This is achieved in that the core pin initially lying at the opening of the key channel, in its part projecting into the key channel and the flat key next to the notch or toothing assigned to the core pin, has a mutual positive connection for fixing the position of the core pin when the key is inserted, and in that At least one recess is provided in the cylinder housing through the cross-sectional plane, the opening of which opens into the bore for the cylinder core, the recess being designed for immersing the core pin and having the stop surface for blocking the further rotation of the cylinder core in the cylinder housing. When the locking cylinder is actuated by an ordinary serial key, after the cylinder core has been turned away from the locked position, the core pin immediately falls into the recess in the cylinder housing and blocks further rotation. Only with a flat key, which also holds the core pin positively in addition to its radial positioning, remains fixed in position even when the cylinder core is rotated, so that the core pin slides over the recess in the cylinder housing without being immersed in it. It is expedient if the core pin has an annular groove as a positive connection and the flat key has a flank engaging in this in the region of the notch or toothing displacing the core pin. The flank can be designed as a hook-like projection, the distance of the annular groove from the head of the core pin corresponding to the distance of the control surface of the key notch or the toothing from the projecting flank, that is to say the hook nose of the form-locking element provided on the key. To support the effect, it is useful if the core pin is a steel pin, as is known, and a magnet is provided in the recess. As a result, a force is exerted on the core pin in the rotational position of the cylinder core as soon as the position of the core pin is aligned with the recess in the cylinder housing in the radial direction. In order to ensure reliable functioning even in the installation positions of the locking cylinder that do not correspond to the usual installation position, the recess or one or more additional recesses in the cylinder housing can be provided in the rotational plane of the core pin.
Um ein Zurückdrehen mit dem falschen Schlüssel zu ermöglichen ist es zweckmäßig, wenn die Ausnehmung in Drehrichtung des Zylinderkerns eine Einlaufschräge aufweist.In order to enable turning back with the wrong key, it is expedient if the recess has an entry slope in the direction of rotation of the cylinder core.
Der Flachschlüssel weist ein besonderes Merkmal auf. Er ist dadurch gekennzeichnet, daß der Kerbe oder Zahnung, für den ersten Kernstift eines Schließzylinders eine in Einschubrichtung des Schlüssels in einen Schlüsselkanal vorspringende Flanke zugeordnet ist. Bei einer vorteilhaften Ausgestaltung ist die Flanke als Teil eines zwischen Schlüsselreide und erster Kerbe oder Zahnung angeordneten über die Steuerfläche der Kerbe oder Zahnung greifenden hakenförmigen Zahnes ausgebildet. Ein Schlüsselrohling ist dadurch gekennzeichnet, daß nächst der Schlüsselreide eine zum Eingreifen in den Schlüsselkanal und zum Festhalten des ersten Kernstiftes, in Einschubrichtung des Schlüssels in den Schlüsselkanal vorspringende Flanke, insbesondere ein Haken, vorgesehen ist.The flat key has a special feature. It is characterized in that the notch or toothing, for the first core pin of a locking cylinder, is assigned a flank projecting into a key channel in the direction of insertion of the key. In an advantageous embodiment, the flank is formed as part of a hook-shaped tooth which is arranged between the key chalk and the first notch or toothing and extends over the control surface of the notch or toothing. A key blank is characterized in that a flank projecting into the key channel and holding the first core pin, in the direction of insertion of the key into the key channel, in particular a hook, is provided next to the key cord.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Zeichnungen dargestellt. Fig. 1 zeigt einen Längsschnitt durch einen Teil eines Schließzylinders mit passendem Flachschlüssel und Fig. 2 einen Querschnitt nach der Linie 11-11 in Fig. 1 bei abgezogenem Flachschlüssel.An embodiment of the subject of the invention is shown in the drawings. Fig. 1 shows a longitudinal section through part of a locking cylinder with a matching flat key and Fig. 2 shows a cross section along the line 11-11 in Fig. 1 with the flat key removed.
Ein Zylinderkern 1 ist in einem Zylindergehäuse 2 drehbargelagert. In fünf parallelen radialen Bohrungen 3 sind jeweils Kernstifte 4 und Gehäusestifte 5 gegen Federkraft verschiebbar. Ein Flachschlüssel 6 greift in einen Schlüsselkanal 7 des Zylinderkerns und weist Kerben bzw. Zahnungen 8 im Bartbereich auf, deren Steuerflächen die Kernstifte 4 zusammen mit den Gehäusestiften 5 verschieben. Der in Fig. 1 dargestellte "richtige" Schlüssel bewirkt eine Verschiebung, bei der die Berührungsflächen zwischen den Kernstiften 4 und den Gehäusestiften 5 genau in der Teilungsfläche zwischen Zylinderkern 1 und Zylindergehäuse 2 liegen. Dadurch kann der Zylinderkern 1 im Zylindergehäuse 2 gedreht werden.A cylinder core 1 is rotatably supported in a cylinder housing 2. In five parallel radial bores 3, core pins 4 and housing pins 5 are each displaceable against spring force. A flat key 6 engages in a key channel 7 of the cylinder core and has notches or serrations 8 in the beard area, the control surfaces of which shift the core pins 4 together with the housing pins 5. The "correct" key shown in FIG. 1 causes a shift in which the contact surfaces between the core pins 4 and the housing pins 5 lie exactly in the dividing surface between the cylinder core 1 and the cylinder housing 2. As a result, the cylinder core 1 can be rotated in the cylinder housing 2.
Der dem Eingang des Schlüsselkanals 7 zunächst liegende Kernstift 4' trägt in seinem in den Schlüsselkanal 7 hineinragenden Teil eine Ringnut 9 als Formschlußelement gegenüber dem Schlüssel 6, der im Bereich seiner den genannten Kernstift 4' zugeordneten Steuerfläche diese übergreifend eine in Einschubrichtung auskragende Flanke 10 in Form eines hakenartigen Vorsprungs als Formschlußelement aufweist, welches mit jenen des Kernstiftes 4' zusammenwirkt. Der vertikale Abstand der Ringnut 9 vom Kopf des Kernstiftes 4' ist gleich dem vertikalen Abstand zwischen der Steuerfläche des Schlüssels 6 und der Flanke 10. Die axiale Länge der Steuerfläche in Einschubrichtung entspricht mindestens den Kopfdurchmesser des Kernstiftes 4' plus der Eingriffstiefe der Formschlußverbindung. Dadurch können die Formschlußelemente ineinandergreifen ohne zu spießen. Die Formschlußverbindung wird infolge des Einrastens der Kernstifte 4 in die Kerben 8 des Schlüssels 6 fixiert. Ein Ausrücken ist nur unter Überwindung der so erzielten Verrastung möglich. In der Einraststellung des Schlüssels 6 hält somit die Flanke 10 den Kernstift 4' unverschiebbar fest.The core pin 4 'initially located at the entrance of the key channel 7 has in its part projecting into the key channel 7 an annular groove 9 as a form-locking element with respect to the key 6, which in the area of its control surface assigned to the said core pin 4' overlaps a flank 10 projecting in the direction of insertion Has the shape of a hook-like projection as a form-locking element, which cooperates with those of the core pin 4 '. The vertical distance of the annular groove 9 from the head of the core pin 4 'is equal to the vertical distance between the control surface of the key 6 and the flank 10. The axial length of the control surface in the direction of insertion corresponds at least to the head diameter of the core pin 4' plus the engagement depth of the positive connection. This allows the interlocking elements to interlock without being skewed. The positive connection is fixed due to the engagement of the core pins 4 in the notches 8 of the key 6. Disengagement is only possible by overcoming the locking achieved in this way. In the locked position of the key 6, the flank 10 thus firmly holds the core pin 4 '.
Im Drehbereich des Kernstiftes 4' (Zeichenebene der Fig.2) liegt eine Ausnehmung 11 im Zylindergehäuse 2, die zum Zylinderkern 1 hin offen ist. Die Ausnehmung 11 ist so dimensioniert, daß der Kernstift 4' in diese eintauchen kann, sollte er nicht gemäß Fig. 1 festgehalten werden. Dieser Fall tritt dann ein, wenn ein Schlüssel 6 zwar mit den passenden Kerben bzw. Zahnungen 8 zur lagerichtigen Positionierung der als Zuhaltungen wirkenden Kern- und Gehäusestifte 4, 5 ausgestattet ist, jedoch keine zusätzliche Formschlußverbindung (z.B. Flanke 10, Ringnut 9) zum Kernstift 4' aufweist. Der Zylinderkern 1 kann dann zwar aus der Sperrstellung geringfügig weggedreht werden; der locker in seiner Bohrung liegende Kernstift 4' fällt jedoch sofort in die Ausnehmung 11 und blockiert die weitere Kerndrehung, sofern er nicht gemäß der Erfindung im Kern festgehalten wird.In the area of rotation of the core pin 4 '(drawing plane of FIG. 2) there is a recess 11 in the cylinder housing 2 which is open towards the cylinder core 1. The recess 11 is dimensioned so that the core pin 4 'can dip into it, should it not be held as shown in FIG. 1. This occurs when a key 6 is equipped with the appropriate notches or serrations 8 for the correct positioning of the core and housing pins 4, 5 acting as tumblers, but no additional positive connection (eg flank 10, annular groove 9) to the core pin 4 '. The cylinder core 1 can then be turned slightly out of the locked position; the core pin 4 'lying loosely in its bore, however, immediately falls into the recess 11 and blocks the further core rotation, unless it is held in the core according to the invention.
Die Ausnehmung 11 verfügt über eine Einlaufschräge 12 und eine Anschlagfläche 13 für den Kernstift 4'. Um den Effekt zu verstären befindet sich am Boden der Ausnehmung 11 ein Permanentmagnet 14. Der Kernstift 4' ist in diesem Fall aus Stahl. Er wird in die Ausnehmung 11 hineingezogen. Damit der Zylinderkern 1 wieder in die Ausgangsstellung zurückgedreht werden kann, ist die Schräge 12 vorhanden. Entlang dieser wird der Kernstift 4' wieder in die Position nach Fig. 1 zurückgeschoben. Der "falsche" Schlüssel kann auch wieder abgezogen werden. Die Ausnehmung kann links und bzw. oder rechts neben dem Gehäusestift 5' vorgesehen sein. Auch kann eine zusätzliche Ausnehmung 11' etwa diametral zur Ausnehmung 11 angeordnet sein, die dann zur Wirkung kommt, wenn der Schließzylinder in nicht üblicher Einbaulage um 180° verdreht montiert ist.The recess 11 has an inlet slope 12 and a stop surface 13 for the core pin 4 '. In order to reinforce the effect, there is a permanent magnet 14 at the bottom of the recess 11. In this case, the core pin 4 'is made of steel. It is drawn into the recess 11. The bevel 12 is provided so that the cylinder core 1 can be turned back into the starting position. Along this, the core pin 4 'is pushed back into the position shown in FIG. 1. The "wrong" key can also be removed. The recess can be provided to the left and / or to the right of the housing pin 5 '. An additional recess 11 'can also be arranged approximately diametrically to the recess 11, which comes into effect when the locking cylinder is mounted rotated by 180 ° in the unusual installation position.
Der Schlüssel 6 kann infolge der Flanke 10 nicht aus einem üblichen Rohling hergestellt werden. Wegen der Hinterschneidung, die die Flanke 10 begrenzt, können auch nicht die üblichen zur Nachschlüsselherstellung zur Anwendung kommenden Fräswerkzeuge verwendet werden. Ein Rohling kann jedoch vom Schloßhersteller so gefertigt werden, daß die Flanke 10 bei sonst noch kerbenlosem Schlüssel bereits vorhanden ist. Es ist dann der radiale Abstand der Ringnut 9 im Kernstift 4' von der Drehachse des Zylinderkernes 1 für diese Serie von Rohlingen konstant, während die Gesamtlänge der entsprechenden Kernstifte von Sperrbereich zu Sperrbereich je nach der Lage der Steuerfläche der ersten Kerbe unterschiedlich sein kann.The key 6 can not be made from a conventional blank due to the edge 10. Because of the undercut that delimits the flank 10, it is also not possible to use the usual milling tools that are used for the production of duplicate keys. However, a blank can be manufactured by the lock manufacturer in such a way that the flank 10 is already present with an otherwise notchless key. The radial distance of the annular groove 9 in the core pin 4 'from the axis of rotation of the cylinder core 1 is then constant for this series of blanks, while the total length of the corresponding core pins can vary from blocking area to blocking area depending on the position of the control surface of the first notch.
An Stelle der Ringnut 9 kann der Kopfbereich des Kernstiftes 4' auch kegelstumpfförmig ausgebildet sein, wobei die Basisfläche des Kegelstumpfes die Kopffläche des Kernstiftes 4' darstellt. Die Flanke des Schlüssels weist dann eine Schräge auf, die auf den Kegelwinkel abgestimmt ist. Die zahnähnlich ausgebildete Flanke 10 nach Fig. 1 kann den Kernstift 4' auch U-förmig übergreifen. Die Flanke 10 kann ferner eine zur Einschubrichtung des Schlüssels schräg verlaufende Stirnkante aufweisen, die sich seitlich tangential an den Kernstift 4' formschlüssig anlegt.Instead of the annular groove 9, the head region of the core pin 4 'can also be frustoconical, the base surface of the truncated cone representing the head surface of the core pin 4'. The flank of the key then has a slope that is matched to the cone angle. The tooth-like flank 10 according to FIG. 1 can also overlap the core pin 4 'in a U-shape. The flank 10 can furthermore have an end edge which runs obliquely to the insertion direction of the key and which engages laterally tangentially on the core pin 4 'in a form-fitting manner.
