- the advantages of the invention consist in the fact that the kink axis of the direction-changing kink arranged outside the longitudinal center plane means that the freedom of movement necessary for breaking the cylinder lock for the vibrating stylus of a Piking pistol is no longer given, since the stylus for realizing the classification of the core pins in the kink of the key channel must be applied. 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 section, the scanning needle still abutting the protruding longitudinal rib of the upper key channel section arranged above the core pins and the protruding longitudinal rib of the lower key channel section and thus getting caught in the labyrinth, which ensures the security against break-in of the cylinder lock.
- 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.
- Bores, 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 are in turn acted upon by spring-loaded locking pins (not shown) held in the cylinder housing 2, so that these locking pins protrude into the bores of the cylinder core 3 when the flat key 6 is not inserted, thereby locking the latter 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 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 core pins guided in bores in the cylinder core 3 along the longitudinal center plane 25 7 cooperate. 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.

Abstract
Description
Die Erfindung betrifft ein Zylinderschloß für Schließanlagen, welches aus einem Zylindergehäuse mit drehbar gelagertem Zylinderkern besteht, wobei der Schlüsselkanal des Zylinderkerns und der Schlüsselschaft eines einführbaren Flachschlüssels im Höhenbereich der Schließkerben mit einem, eine Knickachse aufweisenden richtungsändernden Knick versehen sind, dessen Knickwinkel (α) < 180° ausgelegt ist und der 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 Längsmittenebene 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 from a cylinder housing with a rotatably mounted cylinder core consists of the key channel of the cylinder core and the key shaft an insertable flat key in the height range of Locking notches with a direction-changing direction that has an articulated axis Kink are provided, the kink angle (α) <180 ° and the flat key on its associated with the key shaft Key chest equipped with locking notches over a height range which, in turn, is radial in the bores of the cylinder core guided and on the longitudinal center plane core pins and these again in the cylinder housing provided and spring-loaded locking pins act, and the flat key on its side surfaces Longitudinal ribs and grooves for receiving on the corresponding side walls of the key channel arranged additional longitudinal grooves and ribs.
Ein derartiges Zylinderschloß ist aus der EP 0 596 585 A1 bekannt. Bei dieser Lösung fällt die brustnahe Mittenebene des Schlüsselschafts/des unteren Schlüsselkanalabschnitts mit der gedachten Zuhaltungsebene der nicht dargestellten Zuhaltungsstiftpaare zusammen, während erst nach dem Knickpunkt die rückennahen Mittenebenen der beiden Schlüsselschäfte/oberen Schlüsselkanalabschnitte gegenüber der brustnahen Mittenebene um einen Winkel α geneigt ausgebildet sind.Such a cylinder lock is known from EP 0 596 585 A1. With this solution, the center plane of the key shaft / of the chest falls lower key channel section with the imaginary tumbler level the tumbler pin pairs not shown together, while only after the break point does the center plane of the opposite to the two key shafts / upper key channel sections the center plane near the chest is inclined by an angle α are.
Der Nachteil dieser Lösung besteht darin, daß das Zylinderschloß mit der schwingenden Abtastnadel einer Piking-Pistole von Unbefugten geöffnet werden kann, da die Nadel der Piking-Pistole zwischen dem oberen Ende des Kernstifts und der Längsrippe in den Schlüsselkanal eingeführt und dabei eine ungehinderte Schwingbewegung zur Einordnung der Zuhaltungsstiftpaare, d.h. Herbeiführung der Deckung zwischen den Kontaktflächen des jeweiligen Stiftpaares, bestehend aus Kernstift und Gehäusestift, mit der zwischen Zylinderkern und Gehäusebohrung befindlichen Trennfläche, vollführen kann.The disadvantage of this solution is that the cylinder lock with the swinging stylus of a Piking pistol opened by unauthorized persons because the needle of the Piking pistol is between the upper end of the core pin and the longitudinal rib in the key channel introduced and thereby an unimpeded swinging movement for classification the tumbler pin pairs, i.e. Establishing coverage between the contact surfaces of the respective pair of pins, consisting of Core pin and housing pin, with the between the cylinder core and housing bore separating surface located.
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.This disadvantage could only be achieved by further reducing the Split strips are encountered, but this necessarily leads to weakening of the flat key cross section would lead in the core strip and thus the necessary to ensure the functionality Stability of the flat key must endanger. A slit narrowing however, would also reduce the number of possible Profile variation elements and thus only for realization 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 invention relates to a cylinder lock, which is an actuation with the Piking pistol and still excludes those for the Ensuring the functionality required stability of the Flat key guaranteed and a large number of profile variation elements enables.
Erfindungsgemäß wird dies bei einem Zylinderschloß der obigen Gattung dadurch erreicht, daß die Knickachse des richtungsändernden Knicks außerhalb der Längsmittenebene angeordnet ist, dabei die Mittenebene des oberen Schlüsselkanalabschnitts/oberen Schaftabschnitts und die Mittenebene des unteren Schlüsselkanalabschnitts/unteren Schaftabschnitts die Längsmittenebene jeweils im spitzen Winkel schneidend ausgebildet und daß innerhalb des Höhenbereichs im oberen Schlüsselkanalabschnitt mindestens eine Längsrippe und im unteren Schlüsselkanalabschnitt mindestens eine Längsrippe angeordnet sind, wobei weiterhin bei abgezogenem Schlüssel die Knickachse in Höhe der schlüsselkanalseitigen Enden der Kernstifte und unmittelbar über der Längsrippe vorgesehen ist.According to the invention, this is the case with a cylinder lock of the above type thereby achieved that the articulation axis of the direction changing Knicks is arranged outside the longitudinal center plane, the middle plane of the upper key channel section / upper shaft section and the center plane of the lower key channel section / lower Section of the longitudinal center plane at an acute angle trained and that within the height range in the upper Key channel section at least one longitudinal rib and in the lower Key channel section at least one longitudinal rib are arranged, with the key still at the level of the Key channel-side ends of the core pins and immediately above the Longitudinal rib is provided.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen
2 bis 5 charakterisiert. Advantageous developments of the invention are in the
Der Vorteile der Erfindung bestehen darin, daß durch die außerhalb
der Längsmittenebene angeordnete Knickachse des richtungsändernden
Knicks, 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 consist in the fact that the kink axis of the direction-changing kink arranged outside the longitudinal center plane means that the freedom of movement necessary for breaking the cylinder lock for the vibrating stylus of a Piking pistol is no longer given, since the stylus for realizing the classification of the core pins in the kink of the key channel must be applied. 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 section, the scanning needle still abutting the protruding longitudinal rib of the upper key channel section arranged above the core pins and the protruding longitudinal rib of the lower key channel section and thus getting caught in the labyrinth, which ensures the security against break-in of the cylinder lock.
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 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 Schließkerben
12 der Schlüsselkanal 4 und der Schaft 5 des Flachschlüssels
6 einen richtungsändernden v-förmigen Knick 18 mit außerhalb der
Längsmittenebene 25 liegender Knickachse 18' auf, wobei die Mittenebene
28 des oberen Schlüsselkanalabschnitts 19/oberen Schaftabschnitts
21 und die Mittenebene 29 des unteren Schlüsselkanalabschnitts
20/unteren Schaftabschnitts 22 die Längsmittenebene 25 jeweils
im spitzen Winkel schneidend ausgebildet sind. Der Knickwinkel
α des Knicks 18 beträgt beispielhafte 150°, wobei weiterhin die
Scheitelpunkte des oberen und unteren Schlüsselkanalabschnitts 19,
20 bzw. des oberen und unteren Schaftabschnitts 21, 22 eine Knickachse
18' bilden, an der 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 cylinder lock 1 according to the invention is shown, which consists essentially of the
The
Durch diese 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 Bereich der Knickachse 18' des Schlüsselkanals 4 und damit im Höhenbereich
der schlüsselkanalseitigen Enden der Kernstifte 7 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 ihre dynamische Wirkung gegenüber den Kernstiften nicht
entfalten kann, da ihr Schwingungsbereich durch den Knick 18 als
solchen in Verbindung mit der in den unteren Schlüsselkanalabschnitt
20 hineinragenden Längsrippe 8'' und der in den oberen Schlüsselkanalabschnitt
19 ragenden Längsrippe 8' dermaßen eingeengt wird, daß
sich die Pickingnadel wirkungslos (im Sinne eines beabsichtigten
Nachschließens des Zylinderschlosses) im Schlüsselkanal verfängt.
Bei diesem Vorgang wird die schwingende Pickingnadel durch den Knick
18 und die Längsrippen (8'' bzw. 8') zu einer unbeabsichtigten Bewegung
gezwungen, bei der bewirkt wird, daß sie nicht wirkungsvoll auf
die schlüsselkanalseitigen Enden der Kernstifte 7 aufschlagen kann.This design of the
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. Through the
