Ein derartiger Schließzylinder wird in der
Bei einem Schließzylinder, bei dem die Drehbarkeit des Zylinderkernes unter Anderem von einem Sperrbalken gesperrt ist, ist ein Abtastelement vorgesehen, welches den Sperrbalken bei nicht eingestecktem Schlüssel gegen Verlagerung aus einer Sperrstellung sperrt. Das Abtastelement und der Sperrbalken besitzen ineinandergreifende Passelemente, die in einer das Ineinandergreifen der Passelemente erlaubenden Stellung eine Verlagerung des Sperrbalkens in die Sperrstellung ermöglichen. Das Abtastelement besitzt ein Abtastglied, welches eine von einer Profilrippe oder dergleichen ausgebildete Kodierstufe des Schlüssels abtastet. Dabei wird das Abtastelement vom passenden Schlüssel in eine Passstellung verlagert, in der die erwähnte Passelementepaarung stattfinden kann, so dass beispielsweise ein Vorsprung des Sperrbalkens in eine Ausnehmung des Abtastgliedes eintreten kann. Mit den beiden Passelementepaarungen lässt sich der Schließzylinder mit zwei unterschiedlich kodierten Schlüsseln öffnen, die ansonsten eine gleiche Kodierung aufweisen.In a lock cylinder in which the rotatability of the cylinder core is locked, inter alia, by a locking bar, a sensing element is provided which locks the locking bar with not key inserted against displacement from a locking position. The sensing element and the locking bar have intermeshing mating elements which, in a position permitting the meshing of the mating elements, permit displacement of the barrier bar into the blocking position. The scanning element has a scanning member, which scans a key formed by a rib or the like coding of the key. In this case, the sensing element is displaced by the matching key in a fitting position in which the mentioned matching element pairing can take place, so that, for example, a projection of the locking bar can enter into a recess of the scanning member. With the two pairs of mating elements, the lock cylinder can be opened with two differently coded keys, which otherwise have the same coding.
Derartige Schließzylinder können an einer Schließanlage, die eine Vielzahl von Schließzylindern umfasst, verwendet werden. Die Schließanlage kann einen Zentralschlüssel besitzen, der in der Lage ist, alle oder alle zu einer Gruppe gehörenden Schließzylinder zu schließen. Die Schließanlage kann aber auch einen Schließzylinder besitzen, der von allen Schlüsseln der Schließanlage oder nur von zu einer Gruppe von Schlüsseln gehörenden Schlüsseln geöffnet werden kann.Such lock cylinders can be used on a locking system comprising a plurality of lock cylinders. The locking system may have a central key capable of closing all or all of the lock cylinders belonging to a group. The locking system can also have a lock cylinder that can be opened by all keys of the locking system or only belonging to a group of keys keys.
Der Erfindung liegt die Aufgabe zugrunde, bei einem gattungsgemäßen Schließzylinder das Zusammenspiel zwischen Kodierstufe und Abtastglied zu verbessern.The invention has for its object to improve the interaction between coding and scanning in a generic lock cylinder.
Gelöst wird die Aufgabe durch die im Anspruch 1 angegebene Erfindung.The problem is solved by the invention defined in claim 1.
Zunächst und im Wesentlichen wird vorgeschlagen, dass die zweite Kodierstufe des zweiten Schlüssels das Abtastelement in eine zweite Position bringt, die von der ersten Position verschieden ist. In der zweiten Position nimmt das Abtastelement gegenüber dem Sperrbalken eine zweite Passelementepaarung ein, in der der Sperrbalken in eine Freigabestellung verlagert werden kann. Auch bei dieser Ausgestaltung lässt sich der Schließzylinder mit zwei unterschiedlich kodierten Schlüsseln öffnen, die ansonsten eine gleiche Kodierung aufweisen. Allerdings greifen die beiden Kodierstufen an einem einzigen Abtastglied an. Gehören zur Schließanlage Schließzylinder, die jeweils nur eine erste Passelementepaarung oder jeweils nur eine zweite Passelementepaarung erlauben, so ergibt sich durch die erfindungsgemäße Ausgestaltung des Schließzylinders eine Schließhierarchie allein durch eine Modifikation des Abtastelementes bzw. des Sperrbalkens. In einer besonders bevorzugten Ausgestaltung ist das Abtastelement ein Schieber. Der Schieber kann in Schlüsseleinsteckrichtung, also in Erstreckungsrichtung des Schlüsselkanals verlagert werden. Dies kann gegen die Rückstellkraft einer Feder erfolgen. Das Abtastelement kann in einer Ausnehmung des Zylinderkernes einliegen. Das Abtastglied kann in den Schlüsselkanal hineinragen. Es ragt bevorzugt von einer Seitenwand des Schlüsselkanals in den Schlüsselkanal und kann von einer zur Schlüsselspitze hinweisenden Stufe beaufschlagt werden. Die Stufe kann von einer dort endenden Rippe oder von einer dort endenden, bis in die Schlüsselspitze verlaufenden Nut gebildet sein. Der Schlüssel kann brustseitige Einschnitte bzw. Breitseitenvertiefungen aufweisen, die mit weiteren Zuhaltungselementen, insbesondere Zuhaltungsstiften, zusammen wirken. Die Länge der im Zylinderkern gelagerten Kernstifte definiert dabei die Kodierung, die die Einschnitte bzw. Vertiefungen des Schlüsselschaftes haben müssen, damit der Schlüssel schließt.First and foremost, it is proposed that the second coding stage of the second key bring the scanning element into a second position, which is different from the first position. In the second position, the scanning element assumes a second mating element pairing with respect to the blocking bar, in which the blocking bar can be displaced into a release position. Also in this embodiment, the lock cylinder can be opened with two differently coded keys, which otherwise have a same coding. However, the two coding stages attack a single scanning element. Belong to the locking system lock cylinder, each allow only a first pair of mating elements or only a second pair of mating elements, so results from the inventive design of the lock cylinder a Schließhierarchie solely by a modification of the sensing element or the barrier bar. In a particularly preferred embodiment, the scanning element is a slider. The slide can be moved in Schlüsseleinsteckrichtung, ie in the extension direction of the keyway. This can be done against the restoring force of a spring. The scanning element can einliegen in a recess of the cylinder core. The scanning element can protrude into the key channel. It preferably protrudes from a side wall of the key channel in the key channel and can be acted upon by a pointing to the key tip stage. The step can be formed by a rib ending there or by a groove ending there, extending into the key tip. The key can be chest-side incisions or broadside depressions have, which interact with other tumblers, in particular tumbler pins together. The length of the core pins stored in the cylinder core defines the coding that the cuts or depressions of the key shank must have so that the key closes.
In einer Weiterbildung der Erfindung ist vorgesehen, dass die Passelementepaarung der Eingriff eines Vorsprungs in eine Ausnehmung ist. Die Vorsprünge und Ausnehmungen können jeweils paarweise vorhanden sein. Zwei voneinander beabstandete Vorsprünge wirken mit zwei zueinander beabstandeten Ausnehmungen zusammen. Der mindestens eine Passvorsprung wird vorzugsweise vom Abtastelement ausgebildet. Er ist an der dem Abtastglied gegenüberliegenden Seite des Abtastelementes angeordnet und ragt in eine Ausnehmung hinein, in der sich der Sperrbalken gegen die Rückstellkraft einer Feder verlagern kann. Der Sperrbalken besitzt eine Vielzahl von Passausnehmungen, die in einer Vielzahl von Passelementepaarungen in einer Gegenüberlage zum Passvorsprung liegen. Es sind Zwischenstellungen vorgesehen, in denen der Passvorsprung nicht vor einer Passausnehmung, sondern vor einer Sperrflanke des Sperrbalkens liegt. In dieser Betriebsstellung lässt sich der Sperrbalken nicht in seine Freigabestellung verlagern. Die zu voneinander verschiedenen Passelementepaarungen gehörenden Passausnehmungen sind vorzugsweise jeweils durch einen Sperrflankenabschnitt voneinander getrennt, so dass der Passvorsprung nur dann in eine Passausnehmung eintreten kann, wenn Ausnehmung und Vorsprung genau miteinander fluchten. Eine geringfügige Versetztlage reicht bereits aus, dass ein Abschnitt des Passvorsprungs gegen die Sperrflanke tritt, so dass der Passvorsprung nicht in die Passausnehmung eintreten kann. Des Schlüssel schließt somit nur, wenn die Kodierstufe innerhalb von Fertigungstoleranzen ihre bestimmungsgemäße Position, also einen bestimmungsgemäßen Abstand gegenüber der Schlüsselspitze bzw. gegenüber einer Anschlagflanke des Schlüssels einnimmt, mit der der Schlüssel an der Stirnseite des Zylinderkerns anschlägt.In a further development of the invention it is provided that the mating element pairing is the engagement of a projection in a recess. The projections and recesses may be present in pairs. Two spaced-apart projections cooperate with two mutually spaced recesses. The at least one fitting projection is preferably formed by the sensing element. It is arranged on the side opposite the scanning member of the sensing element and projects into a recess in which the locking bar can move against the restoring force of a spring. The locking bar has a plurality of fitting recesses which lie in a plurality of mating element pairs in a position opposite to the fitting projection. There are intermediate positions provided in which the fitting projection is not in front of a fitting recess, but in front of a blocking edge of the locking bar. In this operating position, the locking bar can not be relocated to its release position. The fitting recesses belonging to different mating element pairings are preferably each separated from each other by a locking flank section, so that the fitting projection can only enter a fitting recess when the recess and the projection are precisely aligned with one another. A slight offset position already sufficient that a portion of the fitting projection occurs against the locking edge, so that the fitting projection can not enter into the fitting recess. The key therefore closes only if the coding stage within their manufacturing tolerances their intended position, ie a proper distance from the key tip or opposite a stop edge of the key occupies, with the key abuts the front side of the cylinder core.

Der Schlüsselschaft 11 endet in einer Schlüsselspitze 16, von der symmetrisch ausgebildete Schrägflanken 29, 28 ausgehen. Auf den beiden, spiegelsymmetrisch zueinander angeordneten Schlüsselbreitseiten erstrecken sich Rippen 19 und den Rippen 19 benachbarte Nuten. Eine Rippe 14 erstreckt sich nicht über die gesamte Länge des Schlüsselschaftes 11, sondern endet vor der Spitze 16 in Form einer Kodierstufe 12, 12'. Zwischen Schlüsselspitze 16 und Kodierstufe 12, 12' erstreckt sich eine Nut 13.The

In der Gehäuseausnehmung 26, deren Öffnung zur Mantelwand des Zylinderkernes 2 gegenüber der Ausnehmung 36 etwa um 90° versetzt liegt, befindet sich ein Abtastelement 5, welches im Ausführungsbeispiel als Schieber ausgebildet ist. Dieser Abtastschieber 5 kann sich in Parallelrichtung zum Schlüsselkanal 7 innerhalb der Ausnehmung 26 bewegen. Er wird von einer Druckfeder 9, deren Wirkrichtung die Verschieberichtung des Abtastschiebers 5 ist, in einer Sperrstellung gehalten, die in der

Der Sperrbalken 4 besitzt auf seiner zum Abtastelement 5 ragenden Seite zwei, jeweils paarweise angeordnete Passausnehmungen 21, 22. Die Passausnehmungen 21, 22 sind Einschnitte in die Sperrflanke 37, deren Breite der Breite der Passvorsprünge 20 entspricht.The locking
Wird in den Schlüsselkanal 7 ein erster passender Schlüssel 10 eingeschoben, bis sein Anschlag 17 an der Stirnfläche des Zylinderkerns 2 anliegt, so bewirkt die Kodierstufe 12 die Beaufschlagung eines vom Abtastelement 5 abragenden Abtastgliedes 6. Das Abtastglied 6 wird von einem Vorsprung aus gebildet, der in ein Fenster 30 hineinragt, welches die Ausnehmung 26 mit dem Schlüsselkanal 7 verbindet. Der Endabschnitt des Vorsprungs 6 ragt somit in den Schlüsselkanal 7 hinein und kann von der Stirnseite der Rippe 14, also der Kodierstufe 12 beaufschlagt werden. Dabei wird in der Endphase des Einschubs des Schlüsselschaftes 11 in den Schlüsselkanal 7 das Abtastelement 5 in Parallelrichtung zur Erstreckungsrichtung des Schlüsselkanals 7 bis in die in den

Besitzt ein nicht dargestellter Zylinderkern einen Sperrbalken 4, bei dem die zweiten Passausnehmungen 22 fehlen, so kann der zweite Schlüssel 10' diesen Schließzylinder nicht schließen, weil die verschobenen Passvorsprünge 20 dann vor der Sperrflanke 37 liegen würden.Has a cylinder core, not shown, a locking
Ähnliche Verhältnisse würden sich einstellen, wenn bei einem ebenfalls nicht dargestellten Schließzylinder der Sperrbalken 4 die ersten Passausnehmungen 21 nicht aufweisen würde. Dann könnte zwar der zweite Schlüssel 10' den Schließzylinder schließen, nicht jedoch der erste Schlüssel 10, da bei seinem Einschub in den Schlüsselkanal 7 das Abtastelement 5 lediglich in eine Stellung verschoben wird, in der die Passvorsprünge 20 vor der Sperrflanke 37 des Sperrbalkens liegen würden.Similar conditions would arise if in a lock cylinder, also not shown, the locking
