Description

Die Erfindung betrifft ein mit einem Doppelbartschlüssel zu betätigendes Sicherheitsschloss mit mehreren in einem Schlossgehäuse angeordneten Zuhaltungen, wobei der Doppelbartschlüssel als alleiniges Mittel zur Aktivierung und Durchführung der Umstellung der Zuhaltung und zur Betätigung des Schließwerks dient.The invention relates to a double-bit key-operated safety lock with a plurality of tumblers arranged in a lock housing, wherein the double-bit key serves as the sole means for activating and implementing the conversion of the tumbler and the operation of the locking mechanism.

Außerdem betrifft die Erfindung einen Schlüssel zur Betätigung eines Sicherheitsschlosses, mit einer Reide, einem Halm und einem Schlüsselbart, auf dem die Codierung des Schlüssels in Form von Schlüsselstufen angeordnet ist.Moreover, the invention relates to a key for operating a security lock, with a Reide, a straw and a key bit, on which the coding of the key is arranged in the form of key stages.

Sicherheitsschlösser für den Einbau z. B. in Tresore sind in unterschiedlichsten Varianten bekannt. Schwachpunkt vieler bekannter Schlösser ist dabei die vergleichsweise einfache Möglichkeit, durch die schlossseitige Öffnung mit geeigneten Werkzeugen in das Schlossinnere zu gelangen, um die Zuhaltungen zu manipulieren. Es gilt daher, die Schlossöffnungen möglichst klein zu halten, was bedingt, dass die Schlüssel ebenfalls klein bauen müssen. Für bisher bekannte Schlösser ist es außerdem notwendig, neben dem Schlüssel für die eigentliche Schließfunktion des Schlosses einen weiteren Schlüssel für die Aktivierung der Umstellung der Zuhaltungen auf eine neue Schließung vorzuhalten. Aus der EP 0 773 338 A1 ist ein umstellbares Doppelbartschloss bekannt, bei dem die Umstellung von vorn, also durch das Schlüsselloch erfolgt. Vorgesehen ist hierzu ein separater Umstellschlüssel als Ergänzung zu dem eigentlichen Doppelbartschlüssel. Gegenstand der CH 579700 A5 ist ein Schloss mit Zuhaltungen und mit einem Halteorgan, das in Schließstellung des Riegels in fluchtende Lücken der Verzahnung der Zuhaltungen eingreift und beim Verschieben des Riegels in seiner Offenstellung aus dem Eingriff mit den Zuhaltungen ausrückbar ist. Um die Umstellung zu ermöglichen oder eben wieder zu verhindern, ist das separate Halteorgan notwendig, welches aktiv ein- bzw. ausgeschaltet werden muss. Diese Vorgänge jedoch erfolgen nicht mit dem Schlüssel, sondern über eine separate Betätigung. Die CH 150857 A zeigt ein Schloss gemäß dem Oberbegriff des Anspruchs 1, bei dem bei jedem Öffnungsvorgang eine Entkopplung der Zuhaltungen stattfindet.Security locks for installation z. As in safes are known in a variety of variants. The weak point of many well-known locks is the comparatively easy way to get through the lock-side opening with suitable tools in the lock interior to manipulate the tumblers. It is therefore important to keep the lock openings as small as possible, which requires that the keys also have to build small. For previously known locks, it is also necessary to hold next to the key for the actual closing function of the lock another key for the activation of the conversion of the tumblers to a new closure. From the EP 0 773 338 A1 is known as a convertible double-beard lock in which the change from the front, so done by the keyhole. Provided for this purpose is a separate Umstellschlüssel as a supplement to the actual double-bitted key. Subject of the CH 579700 A5 is a lock with tumblers and with a retainer, which is in the closed position of the bolt in aligned gaps of the teeth of the tumblers engages and can be disengaged from the engagement with the tumblers when moving the bolt in its open position. In order to enable the change or just to prevent again, the separate holding member is necessary, which must be actively switched on or off. However, these operations do not take place with the key, but via a separate operation. The CH 150857 A shows a lock according to the preamble of claim 1, in which takes place at each opening operation, a decoupling of the tumblers.

Der vorliegenden Erfindung stellt sich damit die Aufgabe, ein Sicherheitsschloss zu schaffen, mit dem besonders klein bauende Schlossöffnungen realisiert werden können bzw. das die Handhabung in Bezug auf die Umstellung der Zuhaltungen einfach ist, wobei gleichzeitig die nach heutigen Maßstäben geltenden Zertifizierungsrichtlinen nachgekommen werden können.The object of the present invention is thus to provide a security lock with which particularly small lock openings can be realized or which is easy to handle with respect to the changeover of the tumblers, whereby at the same time the certification guidelines valid according to today's standards can be met.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Schlüssel von einer Ausgangsstellung in eine Öffnungsrichtung bis zu einer Öffnungsposition drehbar ist und die Umstellung aktiviert ist durch das Drehen des Schlüssels von der Ausgangsstellung entgegen der Öffnungsrichtung, danach wieder zurück in die Ausgangslage und schließlich in die Öffnungsrichtung weiter als bei der normalen Öffnungsstellung bis zum Anschlag und wobei der Schlüssel abziehbar ist und ein neuer Schlüssel mit entsprechender Codierung eingesetzt werden und das Schloss verschließen kannThis object is achieved according to the invention in that the key is rotatable from a starting position in an opening direction to an open position and the change is activated by turning the key from the starting position against the opening direction, then back to the starting position and finally in the opening direction further than the normal open position to the stop and the key is removable and a new key can be used with appropriate coding and lock the lock

Das erfindungsgemäße Schloss kann mit nur einem Schlüssel gehandhabt werden. Dieser Schlüssel dient einerseits zur Betätigung des Schließwerks und andererseits dazu, die Zuhaltungen ohne jegliches zusätzliches Werkzeug umzustellen, indem der Schlüssel zugleich die Einleitung der Umstellung übernimmt. Da der Schlüssel in der Umstellposition abziehbar ist, kann das Schloss vorteilhafterweise auch in dieser Position ausgeliefert werden.The lock according to the invention can be handled with only one key. This key serves on the one hand to operate the locking mechanism and on the other hand to change the tumblers without any additional tools by the key at the same time takes over the initiation of the changeover. Since the key is removable in the changeover position, the lock can be advantageously delivered in this position.

Ergänzend hierzu ist vorgesehen, dass die für das Einführen des Schlüssels in das Schloss vorgesehene Öffnung einen Durchmesser zwischen 9,5 mm und 11 mm aufweist. Z. B. im Tresorbau etwa sind in dieser Spanne liegende Abmessungen insofern von Vorteil, als zunächst nur ein besonders klein bauender Durchbruch an der Tresortür vorzusehen ist. Erst zu einem aus Fertigungsgründen möglichst späten Zeitpunkt braucht dann festgelegt zu werden, ob ein erfindungsgemäßes, ein Kombinations- oder auch ein elektronisches Schloss in den Tresor eingebaut wird. Die für das Einführen des Schlüssels vorgesehene Öffnung in dem Schlossgehäuse und einer Tresortür, der dieses zugeordnet wird, kann damit besonders klein bauen, was wesentlich zur Erhöhung der Sicherheit beiträgt, denn Aufsperrwerkzeuge müssten ebenfalls kleiner bauen und sind erheblich schwerer zu handhaben. Das Maß von 9,5 mm entspricht dabei dem unter statischen Gesichtspunkten gegebenen Mindestwert, das Maß 11 mm unter Berücksichtigung eines Beiwertes der Vorgabe, dass unter Sicherheitskriterien ein Maß von 100 mm2 für eine solche Öffnung nicht überschritten werden darf.In addition, it is provided that the opening provided for the insertion of the key into the lock opening has a diameter between 9.5 mm and 11 mm. For example, in the vault about lying in this range dimensions are advantageous insofar as initially only a particularly small-built breakthrough at the vault door is provided. Only at a time as late as possible for manufacturing reasons then needs to be determined whether an inventive, a combination or an electronic lock is installed in the vault. The provided for the insertion of the key opening in the lock housing and a safe door, which is assigned to this, can thus build very small, which significantly contributes to increasing safety, because Aufsperrwerkzeuge would also have to build smaller and are considerably harder to handle. The dimension of 9.5 mm corresponds to the minimum value given from a static point of view, the dimension 11 mm, taking into account a factor of the requirement that a dimension of 100 mm 2 for such an opening must not be exceeded under safety criteria.

Eine denkbare Lösung für ein solches Schloss, bei dem zur Betätigung des Schließwerks des Schlosses und zur Umstellung der Zuhaltungen derselbe Schlüssel dient, sieht vor, dass das Schloss eine Nuss als Baueinheit zur Umstellung der Zuhaltungen und/oder zur Steuerung der Schließfunktion aufweist. Bei einer solchen Nuss handelt es sich um eine Multifunktionsbaueinheit mit einer Vielzahl von Funktionen. Die Nuss übernimmt neben der eigentlichen Schließfunktion bei entsprechender Betätigung des Schlüssels auch die Steuerung der Umstellung der Zuhaltungen in mehreren Schritten und als kompakt bauendes Bauteil einen Teil der Funktionen, die ansonsten Schlüssel bzw. Schlüsselbart ausüben, insbesondere was über die eigentliche Schließfunktion hinaus das Zusammenspiel mit den Zuhaltungen betrifft. Mit einem derartigen Schloss kann in Verbindung mit einem geeigneten Schlüssel die Funktion des Einleitens der Schlüsselumstellung umgesetzt werden, etwa durch Drehung in die der Öffnung entgegen gesetzte Richtung.A conceivable solution for such a lock, in which the same key is used to operate the locking mechanism of the lock and the changeover of the tumblers, provides that the lock has a nut as a unit for changing the tumblers and / or for controlling the closing function. Such a nut is a multifunctional assembly having a variety of functions. The nut takes over the actual closing function with appropriate operation of the key and the control of the conversion of the tumblers in several steps and as a compact building part of the functions that otherwise exercise key or key bit, especially what about the actual closing function, the interaction with concerns the tumblers. With such a lock, the function of initiating the key change can be implemented in conjunction with a suitable key, such as by rotation in the direction opposite to the opening direction.

Es ist vorgesehen, dass die Nuss mit einem zur Bedienung des Riegels des Schlosses dienenden Riegelmitnehmer und/oder einem zur Umstellung der Zuhaltungen dienenden Umstellzapfen versehen ist. Über ersteren wird die eigentliche Schließfunktion realisiert, d. h. bei Drehung der Nuss aufgrund der Betätigung des Schlüssels wird das Schloss über das Schließwerk geöffnet und geschlossen. Letzterer ist Teil der Baueinheit zur Steuerung der Umstellung der Zuhaltungen.It is envisaged that the nut is provided with a serving for operating the bolt of the lock Riegelmitnehmer and / or serving for the conversion of the tumblers Umstellzapfen. About the former, the actual closing function is realized, d. H. when the nut is turned due to the operation of the key, the lock is opened and closed via the locking mechanism. The latter is part of the unit for controlling the conversion of the tumblers.

Als zentrale Baueinheit des erfindungsgemäßen Schlosses ist in Hinblick auf die Nuss daran gedacht, dass der Riegelmitnehmer und der Umstellzapfen auf der Rückseite der Nuss, in Einführrichtung des Schlüssels betrachtet, angeordnet sind und dass die Nuss mit Riegelmitnehmer und Umstellzapfen im Übrigen einteilig hergestellt ist.As a central unit of the lock according to the invention with respect to the nut is thought that the Riegelmitnehmer and the Umstellzapfen on the back of the nut, viewed in the insertion of the key, are arranged and that the nut with Riegelmitnehmer and Umstellzapfen is otherwise made in one piece.

Konkret ist vorgesehen, dass der Riegelmitnehmer, in Radialrichtung der Nuss gesehen, quer angeordnet ist. Bei entsprechender Betätigung des Schlüssels und Drehen der Nuss wird über diesen Riegelmitnehmer das Öffnen bzw. Schließen des Schließwerks und die Verschiebung der Falle bewerkstelligt.Specifically, it is provided that the Riegelmitnehmer, seen in the radial direction of the nut, is arranged transversely. When the key is turned and the nut is turned, the latch can be used to open or close the lock and move the latch.

Ergänzend dazu ist vorgesehen, dass der Umstellzapfen im Wesentlichen in Radialrichtung auf der Nuss, also in Form eines Kreisbogens angeordnet ist. Während der Riegelmitnehmer also mit seiner Längsseite das auf den Schlüssel ausgeübte Drehmoment auf den Riegel überträgt, schiebt der in Radialrichtung auf der Nuss positionierte Umstellzapfen bei Aktivierung der Umstellfunktion des Schlosses die einzelnen Bauteile in die entsprechenden Positionen, worauf noch einzugehen sein wird.In addition, it is provided that the Umstellzapfen is arranged substantially in the radial direction on the nut, that is in the form of a circular arc. Thus, while the Riegelmitnehmer transmits with its longitudinal side the torque exerted on the key to the bolt, the radially positioned on the nut Umstellzapfen pushes the individual components in the corresponding positions when activating the Umstellfunktion of the lock, which will be discussed later.

Eine weitere Ausführungsform der Erfindung sieht vor, dass der Umstellzapfen in Axialrichtung vor, und/oder in Radialrichtung der Nuss gesehen, hinter dem Riegelmitnehmer angeordnet ist. Dies bedeutet einerseits, dass der Riegelmitnehmer, in Radialrichtung der Nuss betrachtet, hinter dem Umstellzapfen positioniert ist. Andererseits wird hierunter verstanden, dass der Umstellzapfen sich, in Axialrichtung gesehen, weiter von der Ebene der Nuss entfernt befindet als der Riegelmitnehmer. Damit ist eine einwandfreie und unabhängige Funktion in Bezug auf das Schließen einerseits und die Umstellung der Zuhaltungen andererseits gewährleistet.A further embodiment of the invention provides that the Umstellzapfen seen in the axial direction before, and / or in the radial direction of the nut, is arranged behind the Riegelmitnehmer. This means, on the one hand, that the locking catch, viewed in the radial direction of the nut, is positioned behind the changeover pin. On the other hand, this is understood to mean that the Umstellzapfen As seen in the axial direction, is located further from the plane of the nut than the Liegelmitnehmer. This ensures a perfect and independent function in relation to the closing on the one hand and the conversion of the tumblers on the other hand.

Zudem ist vorgesehen, dass die Nuss eine als Einführhilfe für den Schlüssel dienende Zentrierung aufweist. Dabei handelt es sich vorzugsweise um eine oder mehrere in die Nuss integrierte Schrägen, die zu einer automatischen Zentrierung des Schlüssels führen. Diese Lösung kann eine Zentrierung in Form einer Bohrung im Schlüsselhalm in Verbindung mit einem gehäuseseitigen Dorn überflüssig machen. Vorteilhafterweise kommt es durch die stattdessen allenfalls vorgesehene Zentrierbohrung zu keiner Schwächung des Materials mit der Gefahr von späteren Beschädigungen durch Risse, Beulen etc.In addition, it is provided that the nut has a serving as an insertion aid for the key centering. This is preferably one or more inclinations integrated in the nut, which lead to an automatic centering of the key. This solution can make a centering in the form of a hole in the key blade in conjunction with a housing-side mandrel redundant. Advantageously, there is no weakening of the material with the risk of later damage due to cracks, bumps, etc., due to the center hole which is instead provided at best.

In Hinblick auf die Verstellung der Zuhaltungen ist vorgesehen, dass zur Aktivierung der Umstellfunktion des Schlosses in eine Freigabeposition eine in ihrer Längsrichtung verschieblich gelagerte Umstellsperre dient. Diese weist an ihrer der Gehäusewand zugewandten Seite eine Federung auf.With regard to the adjustment of the tumblers is provided that serves to activate the Umstellfunktion of the lock in a release position in its longitudinal direction displaceably mounted Umstellsperre. This has on its side facing the housing wall on a suspension.

Die Umstellsperre wird allerdings bei Drehung des Schlüssels nicht direkt angesprochen. Vielmehr wird vorgeschlagen, dass der Umstellsperre ein Umstellwirbel vorgeordnet ist, dessen Aktivierung über den Umstellzapfen erfolgt. Hierzu wird der Schlüssel bei beabsichtigter Verstellung der Zuhaltungen entgegen der normalen Öffnungsrichtung gedreht. Dabei drückt die Nuss, genauer gesagt der Umstellzapfen, den drehbar gelagerten Umstellwirbel aus seiner Position; Umstellwirbel und -sperre sind aktiviert.However, the changeover lock is not addressed directly when the key is turned. Rather, it is proposed that the Umstellsperre a Umstellwirbel is arranged upstream, the activation takes place via the Umstellzapfen. For this purpose, the key is rotated at intentional adjustment of the tumblers against the normal opening direction. The nut, more precisely the Umstellzapfen, presses the rotatably mounted Umstellwirbel from its position; Umstellwirbel and lock are activated.

Dabei kommt es dazu, dass die Umstellsperre in ihrer Freigabeposition ein Einschwenken eines Sperrwirbels ermöglicht. Letzterer und die Umstellsperre sind hierzu korrespondierend zueinander ausgebildet. Der Sperrwirbel fällt hierzu in die Umstellsperre ein, woraufhin die Aktivierung der Umstellung abgeschlossen ist.It happens that the Umstellsperre allows in its release position a pivoting of a locking vortex. The latter and the Umstellsperre are designed to correspond to each other. The locking vortex falls for this purpose in the Umstellsperre, after which the activation of the conversion is completed.

Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass den Zuhaltungen gemeinsam ein Federbauteil zugeordnet ist, das für die Positionierung der verschiedenen Zuhaltungen sorgt. Anstatt einzelner Federn ist ein auf sämtliche Zuhaltungen federnd einwirkendes, kompaktes und leicht zu installierendes Bauteil in Form einer Blattfeder vorgesehen, das die Zuhaltungen so in der Neutralposition hält, dass der Schlüssel in das Schloss problemlos eingeführt werden kann.A further advantageous embodiment of the invention provides that the tumblers together is assigned a spring component, which ensures the positioning of the various tumblers. Instead of individual springs, a resiliently acting on all tumblers, compact and easy to install component is provided in the form of a leaf spring that holds the tumblers in the neutral position so that the key can be easily inserted into the lock.

Weiterhin wird vorgeschlagen, dass das Gehäuse mit einer Führung für die Zuhaltungen ausgerüstet ist. Diese Führung dient dazu, die Zuhaltungen zu positionieren, wozu Führung und Zuhaltungen korrespondierend zueinander ausgebildet sind. In einer bevorzugten Ausführungsform ist dies der Fall, wenn als Führung ein in die Decke des Gehäuses integrierter Dorn dient. Beim Zusammenbau des Schlossgehäuses positioniert sich der Dorn damit entsprechend zu den Zuhaltungen.Furthermore, it is proposed that the housing is equipped with a guide for the tumblers. This guide is used to position the tumblers, including guide and tumblers are designed to correspond to each other. In a preferred embodiment, this is the case when serving as a guide integrated into the ceiling of the housing mandrel. When assembling the lock housing, the mandrel positions itself accordingly to the tumblers.

Es ist daran gedacht, dass die Zuhaltungen korrespondierend zu dem Dorn ausgebildete Öffnungen aufweisen, die in Hinblick auf eine Schwenkbewegung um den Dorn eine Zwangsführung für die Zuhaltungen darstellen.It is contemplated that the tumblers have apertures formed corresponding to the mandrel which provide a positive guidance for the tumblers with respect to pivotal movement about the mandrel.

Dadurch dass die Schlüsselöffnung mit seitlichen Schürzen versehen ist, die als Führung für den Schlüssel wie als Manipulationsschutz dienen, erfüllen diese eine Doppelfunktion, indem zusätzlich der Zugriff auf die Zuhaltungen erheblich erschwert wird.The fact that the keyhole opening is provided with side skirts, which serve as a guide for the key as a manipulation protection, they fulfill a dual function, in addition, the access to the tumblers is considerably more difficult.

Eine andere Ausführungsvariante der Erfindung sieht vor, dass die Zuhaltungen im Bereich der für das Einführen des Schlüssels vorgesehenen Öffnung Einbauten zur Reduzierung der Größe dieser Öffnung aufweisen.Another embodiment of the invention provides that the tumblers have in the region of the opening provided for the insertion of the key internals to reduce the size of this opening.

Die Erfindung zeichnet sich insbesondere dadurch aus, dass ein Sicherheitsschloss geschaffen ist, das höchsten Sicherheitsanforderungen genügt und damit z. B. für den Einsatz in Tresortüren besonders gut geeignet ist. Der für die Schließfunktion vorgesehene Schlüssel übernimmt zugleich die Einleitung der Umstellung. Ein separater Zugang für ein Werkzeug für die Umstellung der Zuhaltungen auf der Vor- oder Rückseite des Schlosses kann damit entfallen. Ein Schloss kann damit auch bereits im Umstellzustand ausgeliefert werden, zumal der Schlüssel in der Umstellposition abgezogen werden kann. Der Umstellvorgang kann dabei nur komplett umgesetzt werden, wenn der bisher gültige, passende Schlüssel verwendet wird. Dabei übernimmt die Nuss einen Teil der Funktionen, die ansonsten gleich mehrere Bauteile ausüben müssen. Dies bezieht sich in erster Linie auf die Umstellung der Zuhaltungen, sowohl bezüglich der Aktivierung der Umstellung als auch der dann zu erfolgenden Umstellung des Schlosses auf eine neue Schließung. Die Nuss bildet dabei quasi die Fortsetzung des Schlüssels, sie imitiert ihn, indem sie als eine Art Antrieb zum Öffnen des Schlosses bzw. Riegels und zentrale Baueinheit auch in Hinblick auf den Umstellmechanismus der Zuhaltungen dient. Die Nuss weist hierzu an ihrer Vorderseite einen Schließ- und einen Umstellzapfen auf. Dadurch ist ein Multifunktionsbauteil in Form der Nuss geschaffen, das auch insbesondere einen separaten Umstellschlüssel in Zukunft überflüssig macht. Stattdessen wird die Aktivierung der Umstellung durch ein Drehen des Schlüssels entgegen der eigentlichen Öffnungsrichtung eingeleitet.The invention is characterized in particular by the fact that a security lock is created that meets the highest security requirements and thus z. B. is particularly well suited for use in safe doors. The key provided for the closing function also undertakes the initiation of the conversion. A separate access for a tool for the conversion of the tumblers on the front or back of the lock can be dispensed with. A lock can thus already be delivered in Umstellzustand, especially since the key can be removed in the Umstellposition. The changeover process can only be completely implemented if the previously valid, suitable key is used. The nut takes on a part of the functions that otherwise have to exercise several components. This refers primarily to the conversion of the tumblers, both with respect to the activation of the changeover and the then to take place conversion of the castle to a new closure. The nut is virtually the continuation of the key, it imitates him by serving as a kind of drive to open the lock or bolt and central unit also in terms of the Umstellmechanismus the tumblers. The nut has for this purpose on its front a closing and a Umstellzapfen. As a result, a multi-functional component in the form of the nut is created, which also makes in particular a separate Umstellschlüssel unnecessary in the future. Instead, the activation of the change is initiated by turning the key opposite to the actual opening direction.

Der zum erfindungsgemäßen Schloss gehörende Schlüssel genügt aufgrund seiner Kompaktheit besonders hohen Sicherheitsanforderungen, indem ein Schlüssel mit Doppelbart vorgeschlagen wird. Dieser weist beidseitig Schlüsselstufen auf, wobei die maximal entfernt liegenden Enden gegenüberliegender Schlüsselstufen 9 mm bis 11,5 mm voneinander entfernt sind. Der Schlüssel genügt dabei einerseits Stabilitätskriterien und baut andererseits besonders klein, sodass entsprechend die hinter dem Schloss liegende Öffnung z. B. einer Tresorwand ebenfalls entsprechend klein und damit sicherer ausgebildet sein kann.Due to its compactness, the key belonging to the lock according to the invention satisfies particularly high security requirements by proposing a key with a double bit. This has on both sides key levels, with the maximum remote ends of opposing key levels 9 mm to 11.5 mm apart. On the one hand, the key satisfies stability criteria and on the other hand it is particularly small, so that according to the opening behind the lock z. B. a safe wall also correspondingly small and thus can be made safer.

Figur 1 zeigt einen Teil eines Doppelbartschlüssels 7, bestehend aus einem Abschnitt 11 des Schlüsselhalmes 10 mit dem sich daran anschließenden Bart 12 am Ende 43 des Halmes 10. Von den diversen Schlüsselstufen des Bartes 12 sind einige mit dem Bezugszeichen 13, 14, 18, 56, 57 und 58 bezeichnet. Dabei stehen auf der Seite 59 des Bartes 12 die Schlüsselstufe 14 und auf der gegenüberliegenden Seite 60 die Schlüsselstufe 13 maximal hervor. Der Abstand zwischen den in diesem Ausführungsbeispiel maximal hervortretenden Schlüsselstufen 13 und 14 liegt zwischen 9,5 mm und 11 mm. Anders ausgedrückt, der Durchmesser des Schlüsselbartes 12, bezogen auf die jeweils maximal hervorstehenden Schlüsselstufen - hier die Schlüsselstufen 13 und 14 - liegt im Bereich dieser Abmessungen, die einerseits unter Stabilitäts- und andererseits unter Sicherheitskriterien vorteilhaft sind. Mit dem Bezugszeichen 42, 42' ist dieser Durchmesser zusätzlich veranschaulicht. FIG. 1 shows a part of a Doppelbartschlüssels 7, consisting of a portion 11 of the key blade 10 with the adjoining beard 12 at the end 43 of the straw 10. Of the various key stages of the beard 12 are some with the reference numeral 13, 14, 18, 56, 57th and 58. Here are on the side 59 of the beard 12, the key level 14 and on the opposite side 60, the key level 13 maximum out. The distance between the maximum protruding in this embodiment key stages 13 and 14 is between 9.5 mm and 11 mm. In other words, the diameter of the key bit 12, based on the respective maximum protruding key stages - here the key stages 13 and 14 - is in the range of these dimensions, on the one hand under stability and on the other hand are advantageous under safety criteria. The reference numeral 42, 42 ', this diameter is additionally illustrated.

In Figur 2 ist eine Nuss 3 von ihrer Rückseite 6 mit den beiden zentralen Bauteilen Riegelmitnehmer 4 zur Aktivierung der Umstellfunktion des Schlosses und Umstellzapfen 5 zur Umstellung der Zuhaltungen dargestellt. Erkennbar ist dabei, von der Achse 45 aus gesehen, dass der Riegelmitnehmer 4 weiter außen positioniert ist als der Umstellzapfen 5. In Axialrichtung 45 betrachtet, ist der Umstellzapfen 5 weiter von der Ebene der Nuss 3 entfernt als der Riegelmitnehmer 4.In FIG. 2 is a nut 3 from its back 6 with the two central components Riegelmitnehmer 4 for activating the Umstellfunktion the lock and Umstellzapfen 5 shown for the conversion of the tumblers. It can be seen here, as seen from the axis 45, that the latch driver 4 is positioned further outward than the changeover pin 5. When viewed in the axial direction 45, the changeover pin 5 is further away from the plane of the nut 3 than the latch driver 4.

In Einführrichtung des Schlüssels von der Vorderseite 22 her betrachtet ist die Nuss 3 in Figur 3 dargestellt. Auf der Vorderseite 22 ist die Kulisse 23 erkennbar. Mit den Bezugszeichen 16 und 17 sind dabei die als Einführhilfe für den hier nicht dargestellten Schlüssel dienenden Zentrierungen bezeichnet. Vereinfacht sind nun in den Figuren 4, 5 und 6 die Mechanismen im Zusammenhang mit der Aktivierung der Umstellung des Schlosses auf eine neue Schließung dargestellt. Vorteilhaft ist dabei, dass die Aktivierung der Umstellung und deren Durchführung mit einem einzigen Schlüssel erfolgen kann. Dieser ist mit dem Bezugszeichen 7 bezeichnet und in der Darstellung gemäß Figur 4 bereits gegenläufig zur normalen Schlossöffnung im Rahmen der Aktivierung der Umstellung gedreht. Dabei treibt der Umstellzapfen 5 auf der Nuss 3, symbolisiert durch den Pfeil 46, den Umstellwirbel 20 an. Die Umstellsperre 8 befindet sich in ihrer Normalstellung, ein Einschwenken des Sperrwirbels 21 ist dabei blockiert, der Arm 47 der Umstellsperre blockiert den Arm 48 des Sperrwirbels 21.When viewed in the insertion direction of the key from the front side 22, the nut 3 is in FIG FIG. 3 shown. On the front 22, the backdrop 23 can be seen. The reference numerals 16 and 17 are used as the insertion aid for the key, not shown here, centering. Simplified are now in the FIGS. 4, 5 and 6 the mechanisms related to the activation of the conversion of the lock to a new closure shown. It is advantageous that the activation of the conversion and their implementation can be done with a single key. This is denoted by the reference numeral 7 and in the illustration according to FIG. 4 already turned in the opposite direction to the normal lock opening as part of the activation of the changeover. The Umstellzapfen 5 drives on the nut 3, symbolized by the arrow 46, the Umstellwirbel 20. The Umstellsperre 8 is in its normal position, a pivoting of the locking vortex 21 is blocked, the arm 47 of the Umstellsperre blocked the arm 48 of the locking vortex 21st

Eine Aktivierung des Umstellwirbels 20 und damit in der Folge der Umstellsperre 8 ist dann in der Darstellung gemäß Figur 5 erfolgt. Die Umstellsperre 8 ist in Pfeilrichtung 9 verschoben. Die Feder 15 der Umstellsperre 8 dient zur Abstützung der Baugruppe an der Gehäusewand des Schlosses. Der Sperrwirbel 21 kann mit seinem Arm 48 nun in die umstellsperrenseitige Ausbuchtung 49 bzw. in die Umstellsperre 8 einfallen.An activation of Umstellwirbels 20 and thus in the wake of Umstellsperre 8 is then in the illustration according to FIG. 5 he follows. The Umstellsperre 8 is moved in the direction of arrow 9. The spring 15 of the Umstellsperre 8 serves to support the assembly on the housing wall of the castle. The blocking vortex 21 can now come with its arm 48 into the umstellsperrenseitige bulge 49 and in the Umstellsperre 8.

In der Darstellung gemäß Figur 6 ist der Sperrwirbel 21 dann eingefallen; die Aktivierung der Umstellung ist abgeschlossen und der Schlüssel 7 kann wieder in die Grundstellung, hier nicht dargestellt, gedreht werden.In the illustration according to FIG. 6 the locking vortex 21 has then collapsed; the activation of the conversion is completed and the key 7 can be turned back to the basic position, not shown here.

In den Figuren 7 bis 10 ist die Umstellung des Schlosses auf eine neue Schließung dargestellt. In der Darstellung gemäß Figur 7 ist der Schlüssel 7 in Einführposition gezeigt. An dem dem Riegel 29 abgewandten Ende 26 des Gehäuses 2 des Schlosses 1 befindet sich die als Blattfeder 37 ausgebildete Feder 32. Die Feder 32, 37 hält die zuvor durch den Schlüssel in ihre Nullposition transportierten, hier durch die erste Zuhaltung 24 verdeckten, stets in dieser Position. Mit den Bezugszeichen 33 und 34 sind zwei Einbauten versehen, die dazu dienen, die Größe der Öffnung 35 für den Schlüssel 7 zu reduzieren, um die Handhabe von Manipulationswerkzeugen zu erschweren.In the FIGS. 7 to 10 the changeover of the lock to a new lock is shown. In the illustration according to FIG. 7 the key 7 is shown in insertion position. At the end facing away from the latch 29 26 of the housing 2 of the lock 1 is formed as a leaf spring 37 spring 32. The spring 32, 37 keeps the previously transported by the key in its zero position, here covered by the first tumbler 24, always in this position. The reference numerals 33 and 34 are two internals provided, which serve to reduce the size of the opening 35 for the key 7, to complicate the handling of manipulation tools.

Die Darstellung gemäß Figur 8 zeigt nun den Schlüssel 7, nachdem er um ca. 70° gegenüber der in Figur 7 gezeigten Position gedreht wurde. Der Riegel 29 ist dabei noch in der Schließposition. Die Zuhaltungen, hier durch die oberste Zuhaltung 24 verdeckt, sind auf den Schlüssel 7 gefallen und für die aktuelle Schließung sortiert. Mit dem Bezugszeichen 27 ist eine Öffnung in der Zuhaltung 24 bezeichnet, welche in Zusammenspiel mit einem in die Gehäusedecke integrierten Dorn als Zwangsführung für die Zuhaltungen 24 dient.The representation according to FIG. 8 now shows the key 7, after being about 70 ° opposite the in FIG. 7 rotated position was shown. The latch 29 is still in the closed position. The tumblers, here covered by the top tumbler 24, have fallen on the key 7 and sorted for the current closure. Reference numeral 27 designates an opening in the tumbler 24 which, in cooperation with a mandrel integrated in the housing cover, serves as a positive guide for the tumblers 24.

Gezeigt ist dann in Figur 9 ein Schloss 1 nach einer Schlüsseldrehung von insgesamt rund 135°, der Riegel 29 befindet sich in der Öffnungsposition, eine Umstellung ist nicht möglich.Shown is then in FIG. 9 a lock 1 after a key turn of a total of about 135 °, the latch 29 is in the open position, a conversion is not possible.

Aktiviert ist die Umstellung in der Darstellung gemäß Figur 10 durch Drehen des Schlüssels 7 entgegen der Öffnungsrichtung um ca. 80° und wieder in die Ausgangslage. Anschließend ist der Schlüssel 7 weiter als bei der normalen Schlossöffnung bis zum Anschlag (ca. 180°) gedreht und kann nun abgezogen werden. Ein neuer Schlüssel mit entsprechender Codierung kann eingesetzt und das Schloss 1 verschlossen werden. Die Umstellung ist damit abgeschlossen.The conversion is activated in the illustration according to FIG. 10 by turning the key 7 against the opening direction by about 80 ° and back to the starting position. Subsequently, the key 7 is rotated further than in the normal lock opening to the stop (about 180 °) and can now be removed. A new key with appropriate coding can be used and the lock 1 can be closed. The conversion is complete.

Figur 11 zeigt schließlich die Decke 31 eines Schlossgehäuses 2. In diese Decke 31 ist als Führung 19 für die hier nicht dargestellten Zuhaltungen ein von der Decke 31 senkrecht abstehender Dorn 30 integriert. Neben dem Dorn 30 befindet sich die Öffnung 28 für den Schlüssel nebst zwei Schürzen 50, 51, die zugleich als Manipulationsschutz dahingehend dienen, dass der Zugriff von außen auf die hier nicht dargestellten Zuhaltungen verhindert ist. FIG. 11 finally shows the ceiling 31 of a lock housing 2. In this ceiling 31 is integrated as a guide 19 for the tumblers, not shown here, a vertically projecting from the ceiling 31 mandrel 30. In addition to the mandrel 30 is the opening 28 for the key together with two aprons 50, 51, which also serve as manipulation protection to the effect that the access is prevented from the outside to the tumblers, not shown here.
