Definitions
- the invention relates to a cylinder lock for locking systems, which consists of a cylinder housing with a rotatably mounted cylinder core, the cylinder core being provided with a non-rectilinear key channel for inserting an associated flat key and this flat key on its key face associated with the key shaft being equipped with locking notches over a height range, press the core pins, which in turn are radially guided in bores of the cylinder core and lie on the longitudinal center plane, and these in turn are provided and spring-loaded locking pins provided in the cylinder housing, and the flat key has longitudinal ribs and grooves on its side faces for receiving additional longitudinal grooves and ribs arranged on the corresponding side walls of the key channel having.
- Such a cylinder lock is known from DE 30 21 128 C3.
- the key channel which does not run in a straight line, is characterized by a free slit strip of the key channel and the associated flat key by a continuous core strip of its shaft cross section in the height region of the key notches and in the region beyond, which are simple in the form of an arc, in particular a circular arc.
- Such a cylinder lock is intended to make unauthorized actuation with the swinging stylus of a Piking pistol difficult even if the free split strip between the tips of the longitudinal ribs on both sides in the key channel is not particularly narrow, because of the arcuate course of the split strip in the key channel and through that Longitudinal ribs formed labyrinth in the profile of the key channel, a sufficient movement of the scanning needle of a Piking pistol in the direction of the axial movement possibility of the core pins would not be possible.
- the object of the invention is a cylinder lock, which excludes actuation with the Piking pistol and still ensures the stability of the flat key required for ensuring the functionality and enables a large number of profile variation elements.
- this is achieved in a cylinder lock of the above type in that the key channel and the key shaft have a direction-changing bend in the height region of the key notches, the bend angle of which is designed to be ⁇ 180 °, and that at least one longitudinal rib and in the lower one in the height region in the upper key channel section Key channel section are arranged at least one longitudinal rib.
- the kink-shaped design of the key channel means that the freedom of movement required for breaking the cylinder lock for the vibrating stylus of a Piking pistol is no longer available, since the stylus for realizing the arrangement of the core pins in the kink of the key channel must be applied.
- the scanning needle still abutting the projecting longitudinal rib of the upper key channel section arranged above the core pins and the projecting longitudinal rib of the lower key channel section and thus becoming caught in the labyrinth, which ensures the security of the cylinder lock from being broken open.
- the stability of the flat key is ensured on the one hand, even with a small thickness of the shank cross section, by using non-cutting shaping processes for the production of kinks, as a result of undamaged material structures and the occurrence of work hardening, and on the other hand, a larger profile width than the shank thickness is produced, which means that a much larger number of profile variation elements can be used and thus very large profile families are created.
- the cylinder lock 1 according to the invention is shown, which consists essentially of the cylinder housing 2, the cylinder core 3 rotatably mounted therein and the key channel 4 arranged in the cylinder core 3.
- the key channel 4 is used to insert the key shaft 5 of an associated flat key 6 shown in FIGS. 2 and 3.
- Holes (not shown) are provided in the cylinder core 3. which radially guide several core pins 7 of different lengths arranged on the longitudinal center plane 25 of the cylinder core 3, which in turn are acted upon by spring-loaded locking pins (not shown) held in the cylinder housing 2, so that these locking pins project into the bores of the cylinder core 3 when the flat key 6 is not inserted and thus lock it against rotation relative to the cylinder housing 2.
- the key channel 4 is equipped with longitudinal ribs 8, 8 ', 8''and longitudinal grooves 9 (these were essentially provided with reference numerals only on one side of the key channel).
- the flat key 6 shown in FIG. 2 and belonging to the cylinder lock 1 is equipped on its key face 10 with variable locking notches 12, which in turn, when the key 6 is inserted into the key channel 4 of the cylinder core 3, with the holes in the cylinder core 3 along the longitudinal center plane 25 Core pins 7 work together. This is done in such a way that the ends 13 of the core pins 7 on the cylinder housing side form a common contact plane with the ends of the locking pins on the cylinder core side, which plane then runs along the lateral surface 14 (FIG.
- the flat key 6 according to FIG. 3 is further provided on its side surfaces 15 with longitudinal grooves 16 and longitudinal ribs 17 (the reference numerals have only been applied once on each of the side surfaces), which have the longitudinal ribs 8 located on the side surfaces of the key channel 4 and designed as a counter profile, 8 ', 8''and longitudinal grooves 9 communicate.
- the upper section 19 of the key channel 4 is provided with a longitudinal rib 8 'and the lower section 20 of the key channel 4 is provided with a longitudinal rib 8''within the height range 11, the longitudinal rib 8' on the side of the Key channel 4 and the longitudinal rib 8 '' are arranged on the opposite side of the key channel 4.
- the freedom of movement necessary for breaking the cylinder lock 1 for the vibrating scanning needle of a Piking pistol is no longer provided, since the scanning needle must be positioned in the kink 18 of the key channel 4 in order to realize the arrangement of the core pins 7.
- the abrupt change of direction takes place between the upper and lower key channel section 19, 20, so that the scanning needle both against the longitudinal rib 8 ′ of the upper key channel section 19 arranged and protruding above the core pins 7, as well as against that in the area the core pins 7 arranged and protruding longitudinal rib 8 ′′ of the lower key channel section 20 and thus gets caught in the labyrinth due to its flexibility.
- the shaft 5 of the flat key 6, which is provided with a kink 18 in the same way, is extremely stable on the one hand, even with a small thickness 23 of the key shaft 5, through the use of a non-cutting shaping method in the production of the kink, as a result of undestroyed material structures and the occurring work hardening, and ensures the functionality of the cylinder lock .
- the kink 18 also creates a larger key profile width 24 than the thickness 23 of the key shaft 5, as a result of which a large number of profile variation elements 26 and 27 can be used.

Description
Die Erfindung betrifft ein Zylinderschloß für Schließanlagen, welches aus einem Zylindergehäuse mit drehbar gelagertem Zylinderkern besteht, wobei der Zylinderkern mit einem nicht geradlinig verlaufenden Schlüsselkanal zum Einführen eines zugehörigen Flachschlüssels versehen und dieser Flachschlüssel an seiner dem Schlüsselschaft zugeordneten Schlüsselbrust über einen Höhenbereich mit Schließkerben ausgestattet ist, die ihrerseits in Bohrungen des Zylinderkerns radial geführte sowie auf der Langsmittenebene liegende Kernstifte und diese wiederum im Zylindergehäuse vorgesehene und federbelastete Sperrstifte beaufschlagen, und der Flachschlüssel an seinen Seitenflächen Längsrippen und -nuten zur Aufnahme von an den entsprechenden Seitenwänden des Schlüsselkanals angeordneten ergänzenden Längsnuten und -rippen aufweist.The invention relates to a cylinder lock for locking systems, which consists of a cylinder housing with a rotatably mounted cylinder core, the cylinder core being provided with a non-rectilinear key channel for inserting an associated flat key and this flat key on its key face associated with the key shaft being equipped with locking notches over a height range, press the core pins, which in turn are radially guided in bores of the cylinder core and lie on the longitudinal center plane, and these in turn are provided and spring-loaded locking pins provided in the cylinder housing, and the flat key has longitudinal ribs and grooves on its side faces for receiving additional longitudinal grooves and ribs arranged on the corresponding side walls of the key channel having.
Ein derartiges Zylinderschloß ist aus der DE 30 21 128 C3 bekannt. Dabei ist der nicht geradlinig verlaufende Schlüsselkanal durch einen freien Spaltstreifen des Schlüsselkanals und der zugehörige Flachschlüssel von einem durchgehenden Kernstreifen seines Schaftquerschnitts im Höhenbereich der Schlüsselkerben und im darüber hinausgehenden Bereich gekennzeichnet, die einfach bogenförmig, insbesondere kreisbogenförmig ausgebildet sind.Such a cylinder lock is known from DE 30 21 128 C3. The key channel, which does not run in a straight line, is characterized by a free slit strip of the key channel and the associated flat key by a continuous core strip of its shaft cross section in the height region of the key notches and in the region beyond, which are simple in the form of an arc, in particular a circular arc.
Ein solches Zylinderschloß soll die unbefugte Betätigung mit der schwingenden Abtastnadel einer Piking-Pistole selbst dann erschweren, wenn der freie Spaltstreifen zwischen den Kuppen der beiderseitigen Längsrippen im Schlüsselkanal nicht besonders eng ausgebildet ist, da durch den bogenförmigen Verlauf des Spaltstreifens im Schlüsselkanal und dem durch die Längsrippen gebildeten Labyrinth im Profil des Schlüsselkanals eine ausreichende Bewegung der Abtastnadel einer Piking-Pistole in Richtung der axialen Bewegungsmöglichkeit der Kernstifte gar nicht ausführbar wäre.Such a cylinder lock is intended to make unauthorized actuation with the swinging stylus of a Piking pistol difficult even if the free split strip between the tips of the longitudinal ribs on both sides in the key channel is not particularly narrow, because of the arcuate course of the split strip in the key channel and through that Longitudinal ribs formed labyrinth in the profile of the key channel, a sufficient movement of the scanning needle of a Piking pistol in the direction of the axial movement possibility of the core pins would not be possible.
In der Realität läßt ein derartiges Zylinderschloß jedoch die Möglichkeit zu, daß bedingt durch den lediglich allmählich richtungsändernden und damit im wesentlichen richtungsgleichen Verlauf des freien Spaltstreifens, dieser immer noch einen ausreichenden Freiraum aufweist, d.h., die notwendige Bewegungsfreiheit bietet, um mit der schwingenden Abtastnadel einer Piking-Pistole aufgebrochen zu werden. Dabei können die Endflächen der Längsrippen des Schlüsselkanals sogar noch als Führungsflächen für die Abtastnadel wirksam werden. Ein Aufbrechen erscheint weiterhin selbst bei einem eng ausgebildeten Spaltstreifen dann möglich, wenn die Abtastnadel als solche dem Bogenverlauf des freien Spaltstreifens angepaßt bzw. deren Schwingungsbewegung dem Bogenverlauf folgend realisiert wird. Diesem Nachteil könnte nur durch eine weitere Verringerung des Spaltstreifens begegnet werden, was jedoch zwangsweise zur Schwächung des Flachschlüsselquerschnitts im Kernstreifen führen würde und damit die zur Sicherung der Funktionsfähigkeit erforderliche Stabilität des Flachschlüssels gefährden muß. Eine Spaltstreifenverengung würde jedoch auch zu einer Reduzierung der Anzahl möglicher Profilvariationselemente und damit zur Verwirklichung nur kleiner Profilfamilien führen.In reality, however, such a cylinder lock allows the possibility that due to the only gradually changing direction and thus essentially the same direction of the free split strip, this still has sufficient space, that is, offers the necessary freedom of movement to to be broken open with the swinging stylus of a Piking pistol. The end faces of the longitudinal ribs of the key channel can even act as guide surfaces for the scanning needle. A breakup also appears possible even with a narrowly formed split strip if the scanning needle as such is adapted to the curve of the free split strip or its oscillatory movement is realized following the curve. This disadvantage could only be countered by a further reduction in the split strip, which, however, would inevitably lead to a weakening of the flat key cross-section in the core strip and thus must endanger the stability of the flat key required to ensure the functionality. However, a narrowing of the split strips would also lead to a reduction in the number of possible profile variation elements and thus to the realization of only small profile families.
Gegenstand der Erfindung ist ein Zylinderschloß, welches eine Betätigung mit der Piking-Pistole ausschließt und dennoch die für die Sicherung der Funktionsfähigkeit erforderliche Stabilität des Flachschlüssels gewährleistet sowie eine große Anzahl an Profilvariationselementen ermöglicht.The object of the invention is a cylinder lock, which excludes actuation with the Piking pistol and still ensures the stability of the flat key required for ensuring the functionality and enables a large number of profile variation elements.
Erfindungsgemäß wird dies bei einem Zylinderschloß der obigen Gattung dadurch erreicht, daß der Schlüsselkanal und der Schlüsselschaft im Höhenbereich der Schlüsselkerben einen richtungsändernden Knick aufweisen, dessen Knickwinkel α < 180° ausgelegt ist, und daß innerhalb des Höhenbereichs im oberen Schlüsselkanalabschnitt mindestens eine Längsrippe und im unteren Schlüsselkanalabschnitt mindestens eine Längsrippe angeordnet sind.According to the invention, this is achieved in a cylinder lock of the above type in that the key channel and the key shaft have a direction-changing bend in the height region of the key notches, the bend angle of which is designed to be <<180 °, and that at least one longitudinal rib and in the lower one in the height region in the upper key channel section Key channel section are arranged at least one longitudinal rib.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen 2 bis 5 charakterisiert.Advantageous developments of the invention are characterized in the
Der Vorteile der Erfindung bestehen darin, daß durch die knickförmige Ausbildung des Schlüsselkanals die zum Aufbrechen des Zylinderschlosses notwendige Bewegungsfreiheit für die schwingende Abtastnadel einer Piking-Pistole nicht mehr gegeben ist, da die Abtastnadel zur Realisierung der Einordnung der Kernstifte im Knick des Schlüsselkanals angesetzt werden muß. Genau in diesem Bereich des Schlüsselkanals vollzieht sich jedoch die abrupte Richtungsverlaufsänderung zwischen dem oberen und unteren Schlüsselkanalabschnitt, wobei die Abtastnadel weiterhin gegen die oberhalb der Kernstifte angeordnete, vorstehende Längsrippe des oberen Schlüsselkanalabschnitts sowie die vorstehende Längsrippe des unteren Schlüsselkanalabschnitts stößt und sich somit im Labyrinth verfängt, wodurch die Aufbruchsicherheit des Zylinderschlosses gewährleistet wird.
Durch den analog geknickt ausgebildeten Schaft des Flachschlüssels wird einerseits selbst bei geringer Dicke des Schaftquerschnitts durch die Anwendung spanloser Umformungsverfahren für die Knickherstellung, infolge unzerstörter Materialstrukturen und der eintretenden Kaltverfestigung, die Stabilität des Flachschlüssels abgesichert und andererseits auch eine größere Profilbreite als die Schaftdicke erzeugt, wodurch eine wesentlich größere Anzahl an Profilvariationselementen verwendet werden kann und somit sehr große Profilfamilien entstehen.The advantages of the invention are that the kink-shaped design of the key channel means that the freedom of movement required for breaking the cylinder lock for the vibrating stylus of a Piking pistol is no longer available, since the stylus for realizing the arrangement of the core pins in the kink of the key channel must be applied. However, it is precisely in this area of the key channel that the abrupt change in direction takes place between the upper and lower key channel sections, the scanning needle still abutting the projecting longitudinal rib of the upper key channel section arranged above the core pins and the projecting longitudinal rib of the lower key channel section and thus becoming caught in the labyrinth, which ensures the security of the cylinder lock from being broken open.
Due to the shank of the flat key, which has an analogous kink, the stability of the flat key is ensured on the one hand, even with a small thickness of the shank cross section, by using non-cutting shaping processes for the production of kinks, as a result of undamaged material structures and the occurrence of work hardening, and on the other hand, a larger profile width than the shank thickness is produced, which means that a much larger number of profile variation elements can be used and thus very large profile families are created.

In Fig. 1 ist das erfindungsgemäße Zylinderschloß 1 dargestellt, welches im wesentlichen aus dem Zylindergehäuse 2, dem darin drehbar gelagerten Zylinderkern 3 und dem im Zylinderkern 3 angeordneten Schlüsselkanal 4 besteht.
Der Schlüsselkanal 4 dient zum Einführen des Schlüsselschafts 5 eines zugehörigen und in den Fig. 2 und 3 gezeigten Flachschlüssels 6. Im Zylinderkern 3 sind nicht dargestellte Bohrungen vorgesehen, die mehrere auf der Längsmittenebene 25 des Zylinderkerns 3 angeordnete Kernstifte 7 unterschiedlicher Länge radial führen, die ihrerseits von im Zylindergehäuse 2 gehaltenen und federbelasteten Sperrstiften (nicht dargestellt) beaufschlagt werden, so daß diese Sperrstifte bei nicht eingestecktem Flachschlüssel 6 in die Bohrungen des Zylinderkerns 3 ragen und damit diesen gegen Verdrehung gegenüber dem Zylindergehäuse 2 sperren. Zur Realisierung einer Variationsvielfalt ist der Schlüsselkanal 4 mit Längsrippen 8, 8', 8'' und Längsnuten 9 ausgestattet (diese wurden im wesentlichen nur auf einer Seite des Schlüsselkanals mit Bezugszeichen versehen). Der in Fig. 2 gezeigte und zum Zylinderschloß 1 gehörende Flachschlüssel 6 ist an seiner Schlüsselbrust 10 mit variierbaren Schließkerben 12 ausgestattet, die ihrerseits beim Einstecken des Schlüssels 6 in den Schlüsselkanal 4 des Zylinderkerns 3 mit den in Bohrungen des Zylinderkerns 3 entlang der Längsmittenebene 25 geführten Kernstiften 7 zusammenwirken. Dies geschieht derartig, daß die zylindergehäuseseitigen Enden 13 der Kernstifte 7 mit den zylinderkernseitigen Enden der Sperrstifte eine gemeinsame Berührungsebene bilden, die dann entlang der Mantelfläche 14 (Fig. 1) des Zylinderkerns 3 verläuft, so daß nunmehr eine Verdrehung des Zylinderkerns 3 gegenüber dem Zylindergehäuse 2 ermöglicht wird. Der Flachschlüssel 6 ist nach Fig. 3 weiterhin an seinen Seitenflächen 15 mit Längsnuten 16 und Längsrippen 17 versehen (die Bezugszeichen wurden auf jeder der Seitenflächen nur einmal angetragen), die mit den an den Seitenflächen des Schlüsselkanals 4 befindlichen und als Gegenprofil ausgebildeten Längsrippen 8, 8', 8'' und Längsnuten 9 kommunizieren. Dabei weisen im Höhenbereich 11 der Schlüsselkerben 12 der Schlüsselkanal 4 und der Schaft 5 des Flachschlüssels 6 einen richtungsändernden v-förmigen Knick 18 auf, dessen Knickwinkel α = 150° ausgelegt ist, wobei die Scheitelpunkte des oberen und unteren Schlüsselkanalabschnitts 19, 20 bzw. des oberen und unteren Schaftabschnitts 21, 22 einen Knickpunkt 18 bilden, an dem eine abrupte Richtungsverlaufsänderung des Schlüsselkanals 4 bzw. des Querschnitts des Schlüsselschafts 5 eintritt. Weiterhin ist innerhalb des Höhenbereichs 11 der obere Abschnitt 19 des Schlüsselkanals 4 mit einer Längsrippe 8' und der untere Abschnitt 20 des Schlüsselkanals 4 mit einer Längsrippe 8'' versehen, wobei die Längsrippe 8' an der dem Knickwinkel α zugewandten Seite des Schlüsselkanals 4 und die Längsrippe 8'' an der gegenüberliegenden Seite des Schlüsselkanals 4 angeordnet sind.In Fig. 1, the
The
Durch die knickförmige Ausbildung des Schlüsselkanals 4 ist die zum Aufbrechen des Zylinderschlosses 1 notwendige Bewegungsfreiheit für die schwingende Abtastnadel einer Piking-Pistole nicht mehr gegeben, da die Abtastnadel zur Realisierung der Einordnung der Kernstifte 7, im Knick 18 des Schlüsselkanals 4 angesetzt werden muß. Genau in diesem Bereich des Schlüsselkanals 4 vollzieht sich jedoch die abrupte Richtungsverlaufsänderung zwischen dem oberen und unteren Schlüsselkanalabschnitt 19, 20, so daß die Abtastnadel sowohl gegen die oberhalb der Kernstifte 7 angeordnete und vorstehende Längsrippe 8' des oberen Schlüsselkanalabschnitts 19 als auch gegen die im Bereich der Kernstifte 7 angeordnete und vorstehende Längsrippe 8'' des unteren Schlüsselkanalabschnitts 20 stößt und sich somit infolge ihrer Biegsamkeit im Labyrinth verfängt.
Durch den analog mit einem Knick 18 versehenen Schaft 5 des Flachschlüssels 6 ist dieser einerseits selbst bei geringer Dicke 23 des Schlüsselschafts 5 durch die Anwendung eines spanlosen Umformungsverfahrens bei der Knickherstellung, infolge unzerstörter Materialstrukturen und der eintretenden Kaltverfestigung, äußerst stabil und sichert die Funktionsfähigkeit des Zylinderschlosses. Andererseits wird durch den Knick 18 auch eine größere Schlüsselprofilbreite 24 als die Dicke 23 des Schlüsselschafts 5 erzeugt, wodurch eine große Anzahl an Profilvariationselementen 26 bzw. 27 verwendet werden kann.Due to the kink-shaped design of the
