Der Erfindung liegt die Aufgabe zugrunde, ein Schließsystem und einen Flachschlüssel der eingangs genannten Art zu schaffen, der einen verbesserten Kontakt zwischen dem beweglichen Element und den Zuhaltungsstiften ergibt und die Nachahmung des Flachschlüssels weiter erschwert.The invention has for its object a locking system and a flat key of the type mentioned to create an improved contact between the movable element and the tumbler pins and the imitation of the Flat key further complicated.

Diese Aufgabe wird durch die in dem Anspruch 1 bzw. 5 angegebenen Merkmale gelöst.This object is achieved by the features specified in claims 1 and 5, respectively.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.Advantageous refinements and developments of the invention result from the respective subclaims.

Bei dem erfindungsgemäßen Schließsystem endet der mit einem ersten beweglichen Zuhaltungsstift des Stators ausgerichtete erste bewegliche Zuhaltungsstift an seinem vorderen Ende in einem koaxialen zylindrischen Vorsprung, der an seinem Ende eine ebene Stirnfläche aufweist, die mit der Spitze des konischen Kopfes des beweglichen Elementes zusammenwirkt, das in dem Sitz des Schaftes des Flachschlüssels gehaltert ist, der zwei Schmalseiten oder Kanten und zwei Hauptflächen aufweist, wobei in zumindest eine der Hauptflächen die aktiven Vertiefungen eingepägt sind, die das Schloßgeheimnis bezüglich des konischen Kopfes von zweiten beweglichen Zuhaltungsstiften bilden, die mit jeweiligen zweiten, durch eine Feder vorgespannten beweglichen Zuhaltungsstiften des Stators ausgerichtet sind.In the locking system according to the invention, it ends with a first movable one Tumbler pin of the stator aligned first movable tumbler pin on its front end in a coaxial cylindrical projection that has a has flat end face that is movable with the tip of the conical head Interacts element that is held in the seat of the shaft of the flat key which has two narrow sides or edges and two main surfaces, wherein in at least one of the main surfaces are embossed with the active depressions that the Lock secret on the conical head of second movable Form tumbler pins with the respective second, biased by a spring movable tumbler pins of the stator are aligned.

Das erfindungsgemäße Schließsystem bzw. der Flachschlüssel ergeben den Vorteil, daß sich ein zuverlässigerer und wirkungsvollerer und leichter herstellbarer Kontakt zwischen dem mit einem jeweiligen zweiten, durch eine Feder vorgespannten beweglichen Zuhaltungsstift des Stators ausgerichteten ersten beweglichen Zuhaltungsstift des Rotors und dem konischen Kopfes des beweglichen Elementes ergibt, das in dem Sitz des Schaftes des Flachschlüssels gehaltert ist, was im Gegensatz zu dem Kontakt zwischen jeweiligen Mantellinien steht, der sich bei den genannten Teilen bei der ES-A-2 117 489 ergibt, wie aus deren Figur 2 zu erkennen ist.The locking system according to the invention or the flat key give the advantage that a more reliable and effective and easier to establish contact between that with a respective second movable spring-loaded Tumbler pin of the stator aligned first movable tumbler pin of the rotor and the conical head of the movable element which rests in the seat of the Shank of the flat key is held, which is in contrast to the contact between respective surface lines, which is the case with the parts mentioned in ES-A-2 117 489 results, as can be seen from the figure 2.

Bei der vorliegenden Erfindung ist die Achse des Sitzes in dem Schaft des Flachschlüssels mit der gemeinsamen Achse der ersten beweglichen Zuhaltungsstifte des Rotors und des Stators ausgerichtet.In the present invention, the axis of the seat in the shaft of the Flat key with the common axis of the first movable tumbler pins Rotor and the stator aligned.

Der Grund, warum bei der ES-A-2 117 489 diese Achsen gegeneinander versetzt sind, ergibt sich aus der Tatsache, daß sich hierbei zumindest über einen kleinen Teil der bereits genannte Kontakt zwischen Mantellinien ergeben muß. Demgegenüber ergibt sich bei der vorliegenden Erfindung ein Kontakt zwischen einer Spitze und einer ebenen Fläche, der leichter zu erzielen ist (größere Sicherheitsmarge) und der eine einfachere und kostengünstigere Konstruktion ergibt.The reason why in the ES-A-2 117 489 these axes are offset from one another, arises from the fact that at least a small part of the already mentioned contact between surface lines must result. In contrast, it follows in the present invention, contact between a tip and a flat one Area that is easier to achieve (larger safety margin) and one that is easier and cheaper construction results.

Ein weiteres Merkmal der Erfindung ergibt sich daraus, daß bei dem Flachschlüssel das in dem Sitz des Schaftes gehalterte bewegliche Element symmetrisch gegenüberliegend zu dem konischen Kopf einen zweiten konischen Kopf aufweist, der seitlich mit der Spitze eines konischen Kopfes eines der zweiten Zuhaltungsstifte des Rotors zusammenwirkt, die mit den zweiten beweglichen Zuhaltungsstiften des Stators ausgerichtet sind, die durch eine Feder vorgespannt sind.Another feature of the invention results from the fact that in the flat key movable element held symmetrically opposite the seat of the shaft the conical head has a second conical head, the side with the tip a conical head cooperates with one of the second tumbler pins of the rotor, which are aligned with the second movable tumbler pins of the stator, which are biased by a spring.

Eine vorteilhafte Eigenschaft dieses beweglichen Elementes mit symmetrischer Konfiguration besteht darin, daß sich eine Vergrößerung der Kontaktoberfläche zwischen dem in dem Sitz des Schaftes des Flachschlüssels gehalterten beweglichen Element und dem konischen Kopf des zweiten Zuhaltungsstiftes des Rotors ergibt, der mit dem zweiten beweglichen Zuhaltungsstift des Stators ausgerichtet ist. Als Ergebnis ergibt sich eine Vergrößerung der Wirkungsgrades bei der Übertragung der Bewegung.An advantageous property of this movable element with symmetrical Configuration is that there is an increase in the contact surface between the movable element held in the seat of the shaft of the flat key and results in the conical head of the second tumbler pin of the rotor, that with the second movable tumbler pin of the stator is aligned. The result is one Increasing the efficiency of the transmission of the movement.

Eine weitere vorteilhafte Eigenschaft dieses beweglichen Elementes mit symmetrischer Konfiguration besteht darin, daß keine bestimmte Position für seine Montage in dem Sitz des Schaftes des Flachschlüssels festgelegt ist, weil das Element mit einem beliebigen seiner gleichen konischen Endköpfe voraus eingesetzt werden kann. Hierdurch wird die Montage und die hierfür erforderliche Vorrichtung vereinfacht und verbilligt. Another advantageous property of this movable element with symmetrical Configuration is that there is no specific position for its mounting in the seat the shaft of the flat key is fixed because the element with any its same conical end heads can be used ahead. This will make the Assembly and the required device simplified and cheaper.

Gemäß einem weiteren vorteilhaften Merkmal der Erfindung ist vorgesehen, daß in dem Flachschlüssel entsprechend zu einem, mehreren oder allen aktiven Vertiefungen jeder Hauptfläche des Schaftes ein Sitz für ein bewegliches Element derart angeordnet ist, daß die Achse des Sitzes und die Achse der damit zusammenfallenden aktiven Vertiefung in der gleichen Ebene senkrecht zur horizontalen Ebene des Schaftes liegen.According to a further advantageous feature of the invention it is provided that in the Flat keys corresponding to one, more or all active wells each Main surface of the shaft a seat for a movable element is arranged such that the axis of the seat and the axis of the active depression coinciding therewith in the same plane perpendicular to the horizontal plane of the shaft.

Die Auswahl der einen oder anderen Position der aktiven Vertiefung in Übereinstimmung mit der Position eines Sitzes des beweglichen Elementes ermöglicht es, einem bestimmten Vertreiber eine ausschließliche Konzession zur Reproduktion von Schlüsseln zu geben, die zunächst ausschließlich auf den Hersteller beschränkt ist, so daß dieser eine einwandfreie Kontrolle über die ausschließlichen Konzessionen genießt, wobei die Reproduktion nur ausgehend von Flachschlüsselrohlingen (ohne Einprägung von aktiven Vertiefungen) erfolgen kann, denen beim Verlassen der Fabrik eine bestimmte Position der aktiven Vertiefung zugeordnet wird, die mit einem Sitz zusammenfallen soll, der für das bewegliche Element vorgesehen ist, das mit einem mit dem ersten Zuhaltungsstift des Stators ausgerichteten ersten Zuhaltungsstift des Rotors zusammenwirkt.The selection of one or the other position of the active well in accordance with the position of a seat of the movable member allows one certain distributors have an exclusive license to reproduce keys to give, which is initially limited to the manufacturer, so that this enjoys impeccable control over the exclusive concessions, with the Reproduction only from flat key blanks (without embossing active ones Deepening) can take place when leaving the factory a certain position is assigned to the active depression that is to coincide with a seat that is for the movable element is provided, which with a with the first tumbler pin Stator aligned first tumbler pin of the rotor cooperates.

Out This representation clearly shows that the contact between the movable Element 2 and the first movable tumbler pin 6 of the rotor not according to Art of contact between surface lines, but between the tip of the conical Head 21 of the movable element 2 and the flat end face 661 of the first movable tumbler pin 6 occurs. It can also be seen that axis 201 the seat 32 of the shaft 3 of the flat key 1 with the common axis 101 the first movable tumbler pins of the rotor 6 or the stator 81 aligned is.

Gemäß einem weiteren Merkmal der Erfindung weist in dem Flachschlüssel 1 das in dem Sitz 32 des Schaftes 3 gehalterte bewegliche Element 2 symmetrisch gegenüberliegend zu dem konischen Kopf 21 einen zweiten konischen Kopf 23 auf, der seitlich mit der Spitze des konischen Kopfes 75 eines der zweiten Zuhaltungsstifte 7 des Rotors zusammenwirkt, der mit einem zweiten, durch eine Feder 92 vorgespannten beweglichen Zuhaltungsstift 91 des Stators ausgerichtet ist.According to a further feature of the invention, the flat key 1 has the in the seat 32 of the shaft 3 held movable element 2 symmetrically opposite the conical head 21, a second conical head 23, the one with the tip of the conical head 75 one of the second tumbler pins 7 of the rotor cooperates with a second one, by a spring 92 biased movable tumbler pin 91 of the stator is aligned.

Aus den Figuren 2 und 3 ist klar die einfache umkehrbare Form des beweglichen Elementes 2, die seine beliebige Montage und seine Betätigung über einen beliebigen seiner Köpfe 21, 23 ermöglicht, sowie die einfache Konstruktion zu erkennen, die dies für die Sitze des Schaftes 3 des Flachschlüssels 1 ergibt. Diese Umkehrbarkeit macht es unmöglich, die konischen Köpfe 21, 23 voneinander zu unterscheiden, so daß die Bezeichnung 21 für den konischen Kopf gewählt wurde, der mit der ebenen Stirnfläche 661 des ersten beweglichen Zuhaltungsstiftes 6 des Rotors in Kontakt kommt, während die Bezeichnung 23 für den neuen zweiten konischen Kopf des beweglichen Elementes 2 gewählt wurde, der mit dem konischen Kopf 75 des zweiten beweglichen Zuhaltungsstiftes 7 des Rotors in Kontakt kommt.From Figures 2 and 3, the simple reversible form of the movable is clear Element 2, its any assembly and its operation over any its heads 21, 23 allows to recognize as well as the simple construction that this for the seats of the shaft 3 of the flat key 1 results. This reversibility makes it is impossible to distinguish the conical heads 21, 23 from each other, so that the Designation 21 was chosen for the conical head, the one with the flat end face 661 of the first movable tumbler pin 6 of the rotor comes into contact, while the designation 23 for the new second conical head of the movable Element 2 was chosen with the conical head 75 of the second movable Tumbler pin 7 of the rotor comes into contact.

Wie dies in Figur 4 gezeigt ist, entspricht die Transversalebene des Schaftes 3, die für die Achse 201 der Sitze 32 ausgewählt ist, derjenigen der Achsen der aktiven Vertiefungen 36 in der ersten Position des Schaftes 3, wobei jedoch auch andere, auch verschiedene, Positionen gewählt werden können. Außerdem kann in dem Flachschlüssel 1 entsprechend zu einem, mehreren oder allen aktiven Vertiefungen jeder Hauptfläche 34, 35 des Schaftes ein Sitz 32 für ein bewegliches Element 2 derart vorgesehen sein, daß die Achse 201 des Sitzes 32 und die der damit zusammenfallenden aktiven Vertiefung 36 in der gleichen Ebene senkrecht zur horizontalen Achse des Schaftes 3 liegen.As shown in Figure 4, the transverse plane of the shaft 3 corresponds to that for the axis 201 of the seats 32 is selected, that of the axes of the active ones Recesses 36 in the first position of the shaft 3, but other, different positions can also be selected. In addition, in the Flat key 1 corresponding to one, more or all active wells each main surface 34, 35 of the shaft has a seat 32 for a movable element 2 be provided such that the axis 201 of the seat 32 and that of the coincident active recess 36 in the same plane perpendicular to horizontal axis of the shaft 3 lie.

Aus Figur 1 ist klar die große Kontaktfläche zwischen der Spitze des konischen Kopfes 75 des zweiten Zuhaltungsstiftes 7 des Rotors und der Seitenfläche des zweiten konischen Kopfes 23 des beweglichen Elementes 2 zu erkennen.The large contact area between the tip of the conical head is clear from FIG 75 of the second tumbler pin 7 of the rotor and the side surface of the second to recognize conical head 23 of the movable element 2.

In Figur 5 ist ein Querschnitt ähnlich der Figur 3 gezeigt, der eine abgeänderte Ausführungsform darstellt bei der vorgesehen ist, das bewegliche Element 2 an seinem konischen Kopf 21 und/oder seinem zweiten konischen Kopf 23 Abstufungen seines Durchmessers aufweist, die einen ringförmigen Absatz 21a, 23a bilden, wodurch sich ein verringerter Durchmesser an der Spitze des Kopfes derart ergibt, daß eine entsprechende Vergrößerung des Nutzquerschnittes der Endanschläge 32a, 32b des Sitzes 32 ermöglicht wird. Dies ermöglicht eine Verstärkung der Anordnung, die damit gegen Krafteinwirkungen widerstandsfähiger wird.FIG. 5 shows a cross section similar to FIG. 3, which shows a modified one Embodiment in which the movable element 2 is provided its conical head 21 and / or its second conical head 23 gradations of its diameter, which form an annular shoulder 21a, 23a, resulting in a reduced diameter at the tip of the head such that a corresponding increase in the effective cross section of the end stops 32a, 32b the seat 32 is made possible. This enables the arrangement to be reinforced so that it becomes more resistant to force.

Es ist verständlich, daß es auch möglich ist, ein bewegliches Element 2 an einem seiner Köpfe 21 und 23 mit einer Abstufung 21a oder 23a durch Durchmesserverringerung zu versehen, während der andere Kopf keine Abstufung aufweist; in diesem Fall verliert das bewegliche Element jedoch seine Umkehrbarkeit.It is understood that it is also possible to have a movable element 2 on one of his heads 21 and 23 with a gradation 21a or 23a Provide diameter reduction while the other head has no gradation having; in this case, however, the movable element loses its reversibility.
