Der Schließzylinder besitzt ein Schließzylindergehäuse 1, welches eine Höhlung ausbildet in der der Zylinderkern 2 steckt. In dem Gehäuse befinden sich mehrere, reihenartig hintereinander liegende Bohrungen, in welchen die Gehäusestifte 6 der Stiftzuhaltungen angeordnet sind. Diese werden rückseitig von Stiftfedern 7 in Richtung des Kernes beaufschlagt.The lock cylinder has a lock cylinder housing 1, which forms a cavity in that of the cylinder core 2 sticks. There are several in the housing, bores in rows in which the housing pins 6 of the pin tumblers arranged are. These are on the back of pin springs 7 in Direction towards the core.

Der Kern 2 besitzt eine gleiche Anzahl von Kernbohrungen 13, die zu den Gehäusebohrungen fluchten, in diesen Kernbohrungen stecken Kernstifte 5.The core 2 has an equal number of core holes 13, which are aligned with the housing bores, in these Core bores insert core pins 5.

Die Kernstifte 5 besitzen eine Spitze 8, die im Ausführungsbeispiel kegelstumpfförmig ausgebildet ist. Es ist aber auch möglich, diese Spitzen gerundet auszubilden oder mit anderweitigen Schrägen. The core pins 5 have a tip 8, which in the embodiment is frustoconical. It is but it is also possible to round these tips or with other slopes.

Die Spitzen 8 der Kernstifte 5 ragen in jeweils eine Öffnung 12, die der Kernbohrung 13 fluchtend gegenüberliegt. In der Öffnung 12 sitzt eine Ergänzungszuhaltung 9. Die Öffnung 12 setzt sich fort in eine Kernrandausnehmung 11, welche breiter ist, als die Öffnung 12. Im Ausführungsbeispiel liegt in der Kernausnehmung 11, die als Rille ausgebildet ist, ein Balken, von dem Zapfen 14 ausgehen. Die Zapfen 14 liegen in den Öffnungen 12.The tips 8 of the core pins 5 protrude into one Opening 12, which is flush with the core bore 13. A supplementary tumbler sits in the opening 12 9. The opening 12 continues in a core edge recess 11, which is wider than the opening 12. Im Embodiment lies in the core recess 11, the is formed as a groove, a beam from the pin 14 going out. The pins 14 lie in the openings 12.

Der Kernrandausnehmung 11 gegenüberliegend befindet sich eine Sperrausnehmung 10, die dem Schließzylindergehäuse zugeordnet ist. Die Breite und die Länge der Sperrausnehmung entspricht der Breite und der Länge der Kernausnehmung 11. In der Sperrstellung beaufschlagt die vorderer Stirn der Spitze 8 des Kernstiftes 5 die Stirnfläche des Zapfens 14, so daß zufolge des Drucks der Feder 7 die Ergänzungszuhaltung 9 bereichsweise in die Sperrausnehmung 10 verlagert ist. Ein anderer Bereich der Ergänzungszuhaltung 9 liegt in der Kernrandausnehmung 11, so dass zwischen Kern 2 und Schließzylindergehäuse 1 ein Formschluss verwirklicht ist.The core edge recess 11 is located opposite there is a locking recess 10 that the lock cylinder housing assigned. The width and length of the Lockout corresponds to the width and length of the Core recess 11. Actuated in the locked position the front forehead of the tip 8 of the core pin 5 End face of the pin 14, so that due to the pressure the spring 7 the supplementary tumbler 9 in some areas the locking recess 10 is shifted. Another area the supplementary tumbler 9 lies in the core edge recess 11, so that between core 2 and lock cylinder housing 1 a positive connection is realized.

In dieser Stellung ragt die Schräge, die die Spitze 8 ausbildet, nur bereichsweise in die Öffnung 12 hinein, so daß ein Abschnitt der Schräge 8 noch im Schlüsselkanal 3 liegt.In this position, the slope that the tip 8 trained, only partially in the opening 12, so that a portion of the slope 8 is still in the key channel 3 lies.

Wird in den Schlüsselkanal 3 ein Schlüssel eingesteckt, dessen vordere Stirnkante eine spitz zulaufende Schräge aufweist, so kann die Spitze dieser Schräge gegen die Kernstiftspitze 8 treten, um den Kernstift 5 in bekannter Weise gegen den Druck der Feder 7 zu verlagern, bis die Fuge zwischen Kernstift 5 und Gehäusestift 6 mit der Trennebene zwischen Kern und Schließzylindergehäuse fluchtet, so daß die Sperrwirkung der Zuhaltung 5, 6 aufgehoben ist. Hierzu besitzt der Schlüssel tiefenangepasste Schlüsselvertiefungen 15, in welche die Spitzen 8 der Kernstifte 5 treten.If a key is inserted into the key channel 3, the front edge of which is a tapered bevel has, the tip of this slope against the Core pin tip 8 kick to the core pin 5 in a known manner Way to shift against the pressure of the spring 7 until the joint between core pin 5 and housing pin 6 with the parting line between core and lock cylinder housing is aligned so that the locking action of the tumbler 5, 6 is canceled. For this, the key has depth-adjusted Key wells 15 in which the tips 8 of the core pins 5 kick.

Bei eingestecktem Schlüssel werden die Zapfen 14 der Ergänzungszuhaltung 9 nicht mehr von den Kernstiften 5 beaufschlagt, so dass die Ergänzungszuhaltungen 9 aus der Sperrausnehmung 10 austreten kann. Sie wird dann voll von der Kernrandausnehmung 11 aufgenommen. Die Länge des Zapfens 14 ist dabei so bemessen, dass er nicht aus der Öffnung 12 herausguckt.When the key is inserted, the pins 14 are the Supplementary tumbler 9 no longer from the core pins 5 acted on, so that the supplementary tumblers 9 out the locking recess 10 can emerge. Then she will fully received by the core edge recess 11. The The length of the pin 14 is dimensioned so that it does not look out of the opening 12.

In einem nicht dargestellten weiteren Ausführungsbeispiel ist die Ergänzungszuhaltung 9 nicht balkenförmig ausgebildet. Vielmehr besitzt dieses Ausführungsbeispiel zu jedem Kernstift 5 oder nur zu einigen Kernstiften 5 individualisierte Ergänzungszuhaltungen 9.In a further embodiment, not shown the supplementary tumbler 9 is not bar-shaped educated. Rather, this embodiment has for each core pin 5 or only for some core pins 5 individualized additional tumblers 9.

Bei dem in den Fig. 8 bis 9 dargestellten Ausführungsbeispiel ist die Ergänzungszuhaltung 9 ebenfalls als Balken ausgebildet, der in ähnlicher Weise wirkt, wie derjenige der zu den Fig. 1 und 7 beschrieben wurde. Dieser Ergänzungszuhaltungsbalken wird bei dem Ausführungsbeispiel der Fig. 8 bis 11 von Zwischenstiften 17 beaufschlagt. Diese Zwischenstifte 17 liegen mit einem verbreiterten Abschnitt in Kernausnehmungen 11 ein und ragen mit einem verschmälerten Stiftfortsatz 14 in die Öffnungen 12. Der Durchmesser der Öffnungen 12 ist geringer als der Durchmesser der Kernbohrungen. Dies hat zur Folge, dass die kegelstumpfförmigen Spitzen der Kernstifte 5 gegen die Randkante 12' der Öffnung stoßen. Die Randkante 12' begrenzt bei diesem Ausführungsbeispiel die Eintauchtiefe der Spitze der Kernstifte 5 in die Öffnung 12. In the embodiment shown in FIGS. 8 to 9 the supplementary tumbler 9 is also as Beam formed that acts in a similar way as the one that was described with reference to FIGS. 1 and 7. This supplementary tumbler bar is used in the exemplary embodiment 8 to 11 of intermediate pins 17th applied. These intermediate pins 17 are with a widened section in core recesses 11 and protrude with a narrow pin extension 14 in the Openings 12. The diameter of the openings 12 is less than the diameter of the core holes. This has the consequence that the frustoconical tips of the Push core pins 5 against the edge 12 'of the opening. The edge 12 'delimits in this embodiment the immersion depth of the tip of the core pins 5 into the opening 12.

Auch bei diesem Ausführungsbeispiel wird die Ergänzungszuhaltung 9 von der vorderen Stirnseite der Kernstifte gesteuert. Dies erfolgt aber unter Zwischenschaltung der Zwischenstifte 17.The supplementary tumbler is also used in this exemplary embodiment 9 from the front face of the core pins controlled. However, this is done with the interposition the intermediate pins 17.

Wie aus der Fig. 10 zu entnehmen ist, ragen die Stirnenden der verschmälerten Abschnitte der Zwischenstifte 17 in den Schlüsselkanal 3. Dies hat zur Folge, dass die Ergänzungszuhaltung 9 nur dann ihre Freigabestellung einnimmt, wenn der Schlüssel 4 an der entsprechenden Stelle eine Ausnehmung besitzt, in die das Stirnende des Zwischenstiftes 17 eintauchen kann.As can be seen from FIG. 10, the front ends protrude the narrowed portions of the intermediate pins 17 into the key channel 3. This has the consequence that the Supplementary tumbler 9 only then their release position takes when the key 4 on the corresponding Place has a recess in which the front end of the intermediate pin 17 can dip.

In den Fig. 12 und 13 wird die Spitze eines Schlüssels dargestellt, welcher mit dem Schließzylinder zusammenwirken kann. Die Schlüsselspitze besitzt eine Stirnfläche 18, die gerundet ist. Der Rundungsscheitel der Stirnfläche 18 fällt zusammen mit dem Durchdringungspunkt der Symmetrieachse 23 durch die Stirnfläche 18. Die Symmetrieachse 23 ist die Schnittlinie einer durch die Mitte der Schmalseiten gehenden Schmalseiten-Mitteleben 20 und einer durch die Längsmitte der Breitseiten 24 gehende Breitseiten-Mittelebene 21. Die Stirnfläche 18 hat einen im Wesentlichen S-förmigen Verlauf. Von der Stirnfläche 18 gehen wechselseitig unter Beibehaltung der Punktsymmetrie zur Symmetrieachse 23 Schrägflächen 16 aus, die in jeweils eine der beiden Schlüsselbreitseitenflächen 21 auslaufen. Die Begrenzungslinie 16' der Schrägflächen 16, die mit der Begrenzungslinie der Stirnfläche 18 zusammenfällt, schneidet nicht nur die Schlüsselschmalseiten-Mittelebene 20, sondern auch die Schlüsselbreitseiten-Ebene 21, so dass sich Abschnitte 22 der Schrägflächen 16 unmittelbar gegenüberliegen, und nur durch einen schräg verlaufenden Mittelabschnitt 19 der Stirnfläche 18 voneinander getrennt sind.12 and 13 the tip of a key shown, which cooperate with the lock cylinder can. The key tip has an end face 18, which is rounded. The rounding vertex of the Face 18 coincides with the penetration point the axis of symmetry 23 through the end face 18. The axis of symmetry 23 is the section line through the middle of the narrow-side narrow planes 20 and one through the longitudinal center of the broad sides 24 walking broadside middle plane 21. The end face 18 has an essentially S-shaped course. Of the end face 18 go mutually while maintaining the point symmetry to the axis of symmetry 23 inclined surfaces 16, each in one of the two key broad faces 21 expire. The boundary line 16 'of the inclined surfaces 16 with the boundary line the face 18 coincides not only cuts the key narrow side middle level 20, but also the key broadside level 21 so that sections 22 of the inclined surfaces 16 lie directly opposite one another, and only through a sloping central section 19 of the end face 18 separated are.

Auf den Schrägflächen 16 können die gerundeten oder kegelstumpfförmigen Spitzen 8 der Kernstifte 5 aufgleiten.On the inclined surfaces 16, the rounded or Slide frustoconical tips 8 of the core pins 5.
