    • Wie in Fig.1 gut erkennbar ist, besteht das erfindungsgemäße Schloss im wesentlichen aus dem Zylinderkern 2, den als Zuhaltungen vorgesehenen Plättchen 3, dem Sperrbolzen 4 und dem Zylindergehäuse 5. Der zugehörige Schlüssel ist mit 1 bezeichnet.As can be clearly seen in FIG. 1, the lock according to the invention essentially consists of the cylinder core 2, the plate 3 provided as tumblers, the locking pin 4 and the cylinder housing 5. The associated key is denoted by 1.

    Der Sperrbolzen 4 ist über eine Sperrbolzenfeder 12 vorgespannt und weist entlang seines Schaftes abwechselnd Steuernocken 9 und Freistellnuten 10 auf. Seine Spitze ist kegelförmig als Rastnase 21 ausgebildet, und ragt im gesperrten und unverdrehten Zustand in die Rastausnehmung 13 des Zylindergehäuses 5.The locking pin 4 is biased by a locking pin spring 12 and points along it Alternately steer cam 9 and release grooves 10 on. Its tip is conical formed as a detent 21, and protrudes in the locked and untwisted state in the Locking recess 13 of the cylinder housing 5.

    Die über die Plättchenfedern 11 abwechselnd von links und rechts vorgespannten Plättchen 3 sind mit je einem Führungselement 6 versehen, für welches in den Führungsschlitzen 7 eine entsprechende Ausnehmung 24 vorgesehen ist. Weiters weist jedes Plättchen 3 eine Bohrung 8 auf, an der auf einer Seite eine Ausbuchtung 25 vorgesehen ist. Der Durchmesser der Bohrung entspricht in etwa dem der Steuernocken 9 und der Durchmesser der Ausbuchtung 25 entspricht in etwa dem der Freistellnuten 10. Der Schlüssel 1 weist an seinen Flachseiten vom Schlüsselrücken nach innen verlaufende Fräsungen 14 auf. Diese sind, wie in Fig. 1 zu sehen ist, zur Flachseite des Schlüssels konisch geöffnet. The platelets 3, which are biased alternately from the left and right by the platelet springs 11 are each provided with a guide element 6, for which one in the guide slots 7 corresponding recess 24 is provided. Furthermore, each plate 3 has a hole 8 on which a bulge 25 is provided on one side. The diameter of the Bore corresponds approximately to that of the control cam 9 and the diameter of the bulge 25 corresponds approximately to that of the release grooves 10. The key 1 has on its flat sides Milling 14 running inward from the back of the key. These are, as in Fig. 1, too see is conically open to the flat side of the key.

    Im unverdrehten Zustand, wie er in Fig. 2 zu sehen ist, ragt der Sperrbolzen 4 mit seiner Rastnase 21 in die Rastausnehmung 13 und die Plättchen 3 liegen in einer Ebene mit den Freistellnuten 10.In the untwisted state, as can be seen in FIG. 2, the locking pin 4 projects with it Latch 21 in the recess 13 and the plate 3 are in one plane with the Cutout grooves 10.

    Bei im Schlüsselkanal 16 eingeführtem Schlüssel 1 sind, wie in Fig. 3 und Fig. 4 zu sehen ist, die Fräsungen 14 des Schlüssels von den Freistellungen 15 der Plättchen 3 abgetastet. Diese wiederum sind gemäß Fig. 3 bei passendem Schlüssel 1 in einer Weise zu einander gestellt, dass die Bohrungen 8 in fluchtender Position stehen und ein freies Bewegen des in den Bohrungen 8 liegenden Sperrbolzens 4 ermöglichen.With the key 1 inserted in the key channel 16, as can be seen in FIGS. 3 and 4, the millings 14 of the key are scanned from the exemptions 15 of the platelets 3. This 3 are in a manner in relation to one another in accordance with FIG. that the holes 8 are in alignment and free movement of the in the Allow holes 8 lying locking pin 4.

    Bei Verdrehung des Zylinderkerns 2 im Zylindergehäuse 5 durch den Schlüssel 1 wird der Sperrbolzen 4 mit seiner Rastnase 21 aus der Rastausnehmung ausgerückt, wonach der Zylinderkern freigegeben ist.When the cylinder core 2 is rotated in the cylinder housing 5 by the key 1 Locking pin 4 disengaged with its locking lug 21 from the locking recess, after which the Cylinder core is released.

    Bei nicht passendem Schlüssel hingegen steht wie in Fig. 4 zu sehen ist, mindestens eines der Plättchen in Eingriff mit einer der Freistellnuten 10 des Sperrbolzens 4. In dieser gesperrten Stellung liegen die Bohrungen 8 also nicht fluchtend zu einander und verhindern damit eine axiale Bewegung des Sperrbolzens 4. Eine Verdrehung des Zylinderkerns 2 im Zylindergehäuse 5 durch den Schlüssel 1 ist damit blockiert, da die Rastnase 21 in der Rastausnehmung 13 verrastet bleibt.If the key does not match, on the other hand, as can be seen in FIG. 4, there is at least one the plate engages with one of the release grooves 10 of the locking pin 4. In this locked position, the holes 8 are not in alignment with each other and prevent thus an axial movement of the locking pin 4. A rotation of the cylinder core 2 in Cylinder housing 5 by the key 1 is blocked because the locking lug 21 in the Locking recess 13 remains locked.

    Bei einer weiteren Ausführungsform wie sie in Fig.5 und Fig. 6 zu sehen ist, sind an den Plättchen 3 zusätzliche Sperrelemente in Form von Sperrnasen vorgesehen. Diese Sperrnasen 17 ragen in gesperrter Stellung in die Rastnut 18 des Zylindergehäuses 5 und verhindern zusätzlich zum gesperrten Sperrbolzen 4 eine Verdrehung des Zylinderkern 2 im Zylindergehäuse 5. Bei passendem Schlüssel hingegen befinden sich die Sperrnasen 17 innerhalb des Zylinderkerns und greifen nicht in die Rastnut 18 ein.In a further embodiment, as can be seen in FIG. 5 and FIG. 6, the 3 additional locking elements in the form of locking lugs are provided. This Locking lugs 17 protrude in the locked position in the locking groove 18 of the cylinder housing 5 and prevent in addition to the locked locking pin 4 a rotation of the cylinder core 2 in Cylinder housing 5. On the other hand, with a suitable key, the locking lugs 17 are located inside the cylinder core and do not engage in the locking groove 18.

    In der dritten Ausführungsform sind die Plättchen 3 als Kipphebel ausgeführt und weisen kein Führungselement 6 auf. Als Führung dient die Drehachse 19, um die die Plättchen 3 gegen den Schlüssel 1 federnd vorgespannt sind. Die Sperrung ist wie bei den beiden vorangegangenen Ausführungsformen über die Bohrungen 8 gewährleistet, die in gesperrter Stellung in Eingriff mit den Freistellnuten 10 stehen. Der Sperrbolzen 4 ist gegen ein axiales Zurückdrücken aus der Rastausnehmung 13 gesperrt und ein Verdrehen des Zylinderkerns 2 im Zylindergehäuse 5 damit unmöglich. In dieser Ausführungsform ist es möglich, jeweils versetzt zueinander zwei solcher Plättchenreihen, mit dementsprechend zwei Sperrbolzen 4, vorzusehen.In the third embodiment, the plates 3 are designed as rocker arms and have none Guide element 6. The axis of rotation 19 around which the platelets 3 counteract serves as a guide the key 1 are resiliently biased. The lock is like the two previous embodiments ensured through the holes 8, which are locked Stand in engagement with the release grooves 10. The locking pin 4 is against an axial Pushing back out of the locking recess 13 blocked and twisting of the cylinder core 2 impossible in the cylinder housing 5. In this embodiment, it is possible to offset two such rows of platelets to one another, with accordingly two locking bolts 4, provided.

    Der Zylinderkern 2 weist in üblicher Weise an seinem hinteren Ende eine Kupplung 20 auf, die hier lediglich als Schlitz dargestellt ist. Die Kupplung kann beispielsweise zum Betätigen einer Schließmechanik dienen, z.B. zum Versperren von Türen oder Handfeuerwaffen, wo Kleinheit und Sicherheit erforderlich ist.The cylinder core 2 has a clutch 20 at its rear end in a conventional manner is shown here only as a slot. The clutch can be used, for example, to actuate a Serve locking mechanism, e.g. to lock doors or small arms where smallness and security is required.

    Die erfindungsgemäße Konstruktion ist sehr stabil, funktionstüchtig und anwenderfreundlich.The construction according to the invention is very stable, functional and user-friendly.

    Der Schlüssel ist dadurch gekennzeichnet, dass der Schlüssel an seinen Flachseiten quer zur Einsteckrichtung verlaufende Fräsungen aufweist, welche jeweils von den Kanten aus bis etwa zur Mitte des Schlüssels ausgeführt sind. Die mit den Plättchen 3 zusammenwirkenden, Fräsungen 14 verlaufen von den Kanten 27 des Schlüssels eine gerade Strecke bis etwa zur Mittellinie 28 des Schlüssels. Damit wird eine sichere Kodierung des Schlüssels gewährleistet und er erhält ein charakteristisches Schlüsselbild. Die Fräsungen 14 sind zur Flachseite des Schlüssels konisch geöffnet. An der Spitze sind Fasen 22 vorgesehen, um das Einschieben des Schlüssels zu erleichtern. Der Schlüssel ist bevorzugt als Wendeschlüssel ausgebildet. Die entlang jeder Schlüsselkante 27 angeordneten Fräsungen 14 sind zueinander versetzt, entsprechend den versetzt angeordneten Plättchen, die abwechselnd von links und rechts den Schlüssel abtasten.The key is characterized in that the key on its flat sides is transverse to the Milling direction extending millings, each from the edges to about to the center of the key. The interacting with the tiles 3, Mills 14 run a straight distance from the edges 27 of the key to approximately Axis 28 of the key. This ensures secure coding of the key and he gets a characteristic key picture. The millings 14 are on the flat side of the Key opened conically. Chamfers 22 are provided at the tip for insertion of the key. The key is preferably designed as a reversible key. The millings 14 arranged along each key edge 27 are offset from one another, corresponding to the staggered tiles that alternate from the left and the right Scan the key.

    Anhand der Fig. 9 bis 12 wird ein bevorzugtes weiteres Ausführungsbeispiel des erfindungsgemäßen Zylinderschlosses beschrieben.9 to 12, a preferred further embodiment of the described cylinder lock according to the invention.

    Das Zylindergehäuse 5 ist in Blickrichtung der Drehachse des Zylinderkernes 2 etwa halbkreisförmig ausgebildet. Diese Form dient der Anpassung an den Griffbereich eines Maschinenteiles und ist nur beispielhaft dargestellt. Die Bohrungen 29 erlauben den Durchtritt von Befestigungsschrauben. Das Gehäuse ist aus Spritzgusskunststoff. Die Zylinderkernbohrung 32 nimmt den Zylinderkern 2 auf. Der Zylinderkern 2 weist am inneren Ende die Kupplung 20 und zusätzlich noch einen Anschlagstift 33 auf. Dieser Anschlagstift 33 dient der Steuerung weiterer hier nicht dargestellter Maschinenteile. Die Wirkungsweise der Plättchen 3 in Kombination mit dem Sperrbolzen 4 entspricht jener der Ausführungsvariante nach den Fig. 1 bis 6. The cylinder housing 5 is approximately in the direction of view of the axis of rotation of the cylinder core 2 semicircular. This shape is used to adapt to the grip area of a Machine part and is only shown as an example. The holes 29 allow passage of fastening screws. The housing is made of injection molded plastic. The Cylinder core bore 32 receives the cylinder core 2. The cylinder core 2 has on the inside End the clutch 20 and also a stop pin 33. This stop pin 33 is used to control other machine parts, not shown here. The mode of action of Plate 3 in combination with the locking pin 4 corresponds to that of the variant 1 to 6.

    Anders ist hier die Steuerung und Bewegung des Sperrbolzens 4. Die Rastnase 21 ragt in eine radiale Bohrung 34 des Zylinderkernes 2, in der eine Rastkugel 35 beweglich angeordnet ist. In der in Fig. 10 dargestellten Nullage des Zylinderkernes 2 mit eingeschobenem Schlüssel 1 drückt die Sperrbolzenfeder 12 den Sperrbolzen 4 in die dargestellte Lage, so dass die Rastnase 21 in der radialen Bohrung 34 liegt und damit die Rastkugel 35 so weit anhebt und festhält, dass die Rastkugel 35 in eine Rastausnehmung 36 des Zylindergehäuses 5 ragt. Dadurch überragt die Rastkugel 35 die durch die Zylinderkernbohrung 32 gebildete Zylinderdrehfläche 37, wodurch ein Verdrehen des Schlosses gehindert ist.The control and movement of the locking pin 4 is different here. The latch 21 projects into a radial bore 34 of the cylinder core 2, in which a detent ball 35 is movably arranged. In the zero position of the cylinder core 2 shown in FIG. 10 with the key 1 inserted presses the locking pin spring 12, the locking pin 4 in the position shown, so that the Latch 21 is located in the radial bore 34 and thus the locking ball 35 so far and holds that the locking ball 35 projects into a locking recess 36 of the cylinder housing 5. As a result, the detent ball 35 projects beyond the one formed by the cylinder core bore 32 Cylinder rotating surface 37, whereby rotation of the lock is prevented.

    Die Fig. 12 zeigt einen Schnitt durch den Zylinderkern 2 in Höhe der Rastkugel 35. Beim Verdrehen des Zylinderkernes 2 mit einem richtigen Schlüssel wird die Rastkugel 35 aus der Rastausnehmung 36 heraus und nach unten in die radiale Bohrung 34 gedrückt. Dabei wird der Sperrbolzen 4 gegen den Druck der Sperrbolzenfeder 12 verschoben, was nur dann möglich ist, wenn alle Plättchen 3 in der für die Freigabe erforderlichen Stellung stehen, in der alle Bohrungen 8 fluchten, wie in Fig. 11 gezeigt ist.Fig. 12 shows a section through the cylinder core 2 at the level of the locking ball 35. When Turning the cylinder core 2 with a correct key, the locking ball 35 from the Snap recess 36 out and pressed down into the radial bore 34. Doing so the locking pin 4 moved against the pressure of the locking pin spring 12, only then is possible if all the tiles 3 are in the position required for the release, in the all holes 8 are aligned, as shown in Fig. 11.

    Diese Konstruktion nach den Fig. 9 bis 12 hat den Vorteil, dass die Steuerung des Sperrbolzens 4 durch einen weitgehend verschleißfreien Teil erfolgt, nämlich durch die Rastkugel 35. Weiters kann die Rastkugel 35 hohe Drehkräfte aufnehmen, was insbesondere dann wichtig ist, wenn das Zylindergehäuse 5 aus Kunststoff besteht und nicht aus härterem Metall.This construction according to FIGS. 9 to 12 has the advantage that the control of the Locking pin 4 is carried out by a largely wear-free part, namely by the Locking ball 35. Furthermore, the locking ball 35 can absorb high rotational forces, which in particular is important if the cylinder housing 5 is made of plastic and not of harder Metal.

    Die radiale Bohrung 34 muss nicht genau radial sein, sondern kann auch schräg derart verlaufen, dass sie einerseits mit der Rastnase 21 und andererseits mit der Rastausnehmung 36 zusammenwirkt.The radial bore 34 need not be exactly radial, but can also be oblique run that they on the one hand with the locking lug 21 and on the other hand with the locking recess 36 interacts.
