Description

Die Erfindung betrifft ein Schloss mit einem Zylinderkern, in dem quer zur Zylinderkernachse plättchenförmige Zuhaltungen verschieblich sind, die durch ein seitlich der Zuhaltung im Zylinderkern angeordnetes Federelement in eine über den Zylinderkernmantel hinausstehende, die Zylinderkerndrehung sperrende Lage und durch einen passenden Schlüssel in eine über den Zylinderkernmantel nicht hinausstehende Lage bringbar sind, wobei das Federelement mit dem ersten Ende an der Zuhaltung und mit dem gegenüberliegenden zweiten Ende am Zylinderkern anliegt.The invention relates to a lock with a cylinder core, in which plate-like tumblers can be displaced transversely to the cylinder core axis, which by means of a spring element arranged laterally in the cylinder core in a protruding position beyond the cylinder core jacket, blocking the cylinder core rotation, and by a suitable key in a cylinder jacket not protruding position can be brought, the spring element with the first end of the tumbler and the opposite second end against the cylinder core.

Ein solches Schloss ist aus der DE-A-2 263 265 bekannt. Bei der Montage dieser Schliesszylinder werden in die Zylinderkerne, ehe sie in das Schloss eingefügt werden, zuerst die die Zuhaltungen beaufschlagenden Schraubendruckfedern eingesetzt und danach die Plättchenzuhaltungen in Schlitze des Zylinderkerns derart eingeschoben, dass die jeweils an der Zuhaltung vorspringende Nase am oberen Ende der Schraubendruckfeder zur Anlage gelangt. In dieser Weise mit Federn und Zuhaltungen versehene Zylinderkerne müssen sehr vorsichtig gehandhabt werden, da die Zuhaltungen leicht aus dem Zylinderkern herausfallen. Um dies zu verhindern, ist es bekannt durch einen zusätzlichen Arbeitsgang mindestens einen Rand der schlitzförmigen Ausnehmung im Zylinderkern nach innen etwas einzubiegen, so dass die Einführungsöffnung verkleinert und ein Herausfallen der Zuhaltung verhindert wird. Ferner ist es bekannt die Zuhaltung durch einen eingesteckten Schlüssel im Zylinderkern gegen ein Herausfallen zu sichern, siehe DE-B-2 135 106. Aus der FR-A-2 033 437 ist es bekannt, nach dem Einsetzen der Plättchenzuhaltungen ein Metallteil seitlich in den Zylinderkern einzuschieben, das in eine seitliche Ausnehmung der Zuhaltung hineinreicht und nur eine begrenzte Bewegung der Zuhaltung zulässt. Ferner ist es aus dieser Schrift bekannt, an der Zuhaltung seitlich einen Vorsprung anzuformen, der eine Fläche des Zylinderkerns hintergreift. Diese Konstruktionen sind aufwendig.Such a lock is known from DE-A-2 263 265. When assembling these locking cylinders, the helical compression springs that act on the tumblers are first inserted into the cylinder cores before they are inserted into the lock and then the plate tumblers are inserted into the slots in the cylinder core in such a way that the protruding nose on the tumbler at the top end of the helical compression spring Plant arrives. Cylinder cores provided with springs and tumblers in this way must be handled very carefully since the tumblers easily fall out of the cylinder core. In order to prevent this, it is known to bend inward at least one edge of the slot-shaped recess in the cylinder core somewhat by an additional work step, so that the insertion opening is reduced and the tumbler is prevented from falling out. Furthermore, it is known to secure the tumbler against falling out by means of an inserted key in the cylinder core, see DE-B-2 135 106. From FR-A-2 033 437 it is known to insert a metal part laterally into the after the insertion of the plate tumblers To insert the cylinder core, which extends into a lateral recess of the tumbler and allows only a limited movement of the tumbler. Furthermore, it is known from this document to laterally form a projection on the tumbler which engages behind a surface of the cylinder core. These constructions are complex.

Aufgabe der Erfindung ist es, einen konstruktiv einfach aufgebauten Zylinderkern mit Zuhaltungen derart zu verbessern, dass nach dem Einsetzen von Federelementen und Zuhaltungen diese nicht aus dem Zylinderkern herausfallen können obwohl nach dem Einsetzen zusätzliche Massnahmen und Arbeitsvorgänge nicht durchgeführt wurden.The object of the invention is to improve a structurally simple cylinder core with tumblers in such a way that after the insertion of spring elements and tumblers these cannot fall out of the cylinder core although additional measures and operations have not been carried out after the insertion.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Federelement derart schräg zur Bewegungsrichtung der Zuhaltung angeordnet ist, dass das erste Ende näher der Zuhaltung liegt als das zweite Ende, und dass eine zur Bewegungsrichtung parallele Zuhaltungsseitenwand, an der die Anlagefläche für das Federelement vorspringt, im Bereich des ersten Federelementenendes eine Ausnehmung aufweist, in der das Federelement teilweise einliegt.This object is achieved according to the invention in that the spring element is arranged at an angle to the direction of movement of the tumbler such that the first end is closer to the tumbler than the second end, and that a tumbler side wall parallel to the direction of movement, on which the contact surface for the spring element projects, im Area of the first spring element end has a recess in which the spring element partially lies.

Bei dieser Lösung hindert nicht nur die Zuhaltung ein Herausfallen des Federelementes aus dem Zylinderkern, sondern das Federelement hindert auch die Zuhaltung an ein Herausgleiten aus der Öffnung des Zylinderkerns. Dieser gegenseitige Halt wird im wesentlichen dadurch erreicht, dass das Federelement in seiner Bewegungsrichtung schräg zur Bewegungsrichtung der Zuhaltung liegt und die Zuhaltung während des Einsetzens das Federelement zuerst zusammendrückt und erst nach einem so weiten Einstecken, das etwa der höchsten späteren Stellung der Zuhaltung entspricht, das Federelement in eine seitliche Ausnehmung an der Zuhaltung einschnappt und dann eine über die höchste Stellung der Zuhaltung hinausgehende Bewegung der Zuhaltung aus dem Zylinderkern heraus verhindert.In this solution, not only does the tumbler prevent the spring element from falling out of the cylinder core, but the spring element also prevents the tumbler from sliding out of the opening of the cylinder core. This mutual hold is essentially achieved in that the spring element is inclined in its direction of movement to the direction of movement of the tumbler and the tumbler first compresses the spring element during insertion and only after such a wide insertion, which corresponds approximately to the highest later position of the tumbler, that Spring element snaps into a lateral recess on the tumbler and then prevents the tumbler from moving out of the cylinder core beyond the highest position of the tumbler.

Ein solcher mit Federelementen und Zuhaltungen versehener Zylinderkern kann sofort nach dem Einstecken dieser Teile ohne besondere Sorgfalt gehandhabt werden, so dass die Montage wesentlich einfacher und angenehmer wird. Ein Einstecken eines Schlüssels in den Zylinderkern zum Halten der Zuhaltungen während der Weitermontage ist nicht erforderlich und ein Wechsel von Zylinderkernen als auch von einzelnen Zuhaltungen ist leicht möglich.Such a cylinder core provided with spring elements and tumblers can be handled immediately after inserting these parts without special care, so that the assembly is much easier and more convenient. It is not necessary to insert a key into the cylinder core to hold the tumblers during further assembly, and it is easy to change the cylinder cores as well as individual tumblers.

Vorzugsweise wird vorgeschlagen, dass die Federelementenachse mit der Bewegungsrichtung der Zuhaltung einen Winkel von a = 3 bis 30 Grad, insbesondere von 5 bis 20 Grad bildet. Als besonders zweckmässig hat sich ein Winkel von 8 bis 10 Grad erwiesen.It is preferably proposed that the spring element axis form an angle of a = 3 to 30 degrees, in particular 5 to 20 degrees, with the direction of movement of the tumbler. An angle of 8 to 10 degrees has proven to be particularly expedient.

Vorzugsweise wird vorgeschlagen, dass die eine Ausnehmung für das Federelement aufweisende Zuhaltungsseitenwand eine zur Bewegungsrichtung und Zylinderkernachse parallele Schmalseite der Zuhaltung ist und die Federelementenachse in einer zur Zylinderkernachse rechtwinkligen Ebene liegt. Alternativ kann aber auch die eine Ausnehmung für das Federelement aufweisende Zuhaltungsseitenwand eine zur Bewegungsrichtung parallele und zur Zylinderkernachse rechtwinklige Flachseite der Zuhaltung sein und die Federelementenachse in einer Ebene liegen, die gleich oder parallel einer Ebene ist, die von der Zylinderkernachse und der Zuhaltungsmittelachse gebildet wird.It is preferably proposed that the tumbler side wall having a recess for the spring element is a narrow side of the tumbler parallel to the direction of movement and the cylinder core axis and the spring element axis lies in a plane perpendicular to the cylinder core axis. Alternatively, however, the tumbler side wall having a recess for the spring element can be a flat side of the tumbler parallel to the direction of movement and perpendicular to the cylinder core axis and the spring element axis lie in a plane that is the same or parallel to a plane that is formed by the cylinder core axis and the tumbler center axis.

In einer zeichnerisch nicht dargestellten Alternative, kann die Ausnehmung von einem Vorprung der Zuhaltungsseitenwand gebildet sein. Ferner wird vorgeschlagen, dass die Zuhaltungsanlagefläche einen Teil der Ausnehmungswandung bildet. Besonders vorteilhaft ist es, wenn eine Ausnehmungswand parallel zur Federelementenachse ist. Hierbei kann die Zuhaltungsanlagefläche rechtwinklig zur übrigen Ausnehmungswand sein.In an alternative, not shown in the drawing, the recess can be formed by a projection of the tumbler side wall. It is also proposed that the tumbler contact surface forms part of the recess wall. It is particularly advantageous if a recess wall is parallel to the spring element axis. Here, the tumbler contact surface can be perpendicular to the rest of the recess wall.

Eine besonders sichere Führung der Zuhaltung als auch ein optimales Sperren der Zuhaltung um ein Herausfallen zu verhindern wird dadurch erreicht, dass die auf der der Federanlagefläche abgewandten Seite der Ausnehmung anschliessende Zuhaltungsseitenwand in einer Ebene liegt, die zur Bewegungsrichtung der Zuhaltung parallel ist und das Federelement im schrägen Winkel schneidet.A particularly safe guiding of the tumbler as well as an optimal locking of the tumbler to prevent it from falling out is achieved in that the tumbler side wall adjoining the side of the recess facing away from the spring contact surface lies in a plane that is parallel to the direction of movement of the tumbler and the spring element in cuts oblique angle.

Eine platzsparende Bauweise wird dadurch erzielt, dass das Federelement einen grösseren Durchmesser aufweist als die Breite der für die Zuhaltung vorgesehenen Zylinderkernausnehmung in Richtung der Zylinderkernachse und dass das Federelement in einer schrägen Bohrung einliegt, die von der Zylinderkernausnehmung durchdrungen ist. Auch wird vorgeschlagen, dass bei Einführen der Zuhaltung das Federelement durch die zuerst in den Zylinderkern eingeführte Seite insbesondere die Unterseite der Zuhaltung zusammendrückbar ist, bis das Federelement in die endgültige Lage einschnappt.A space-saving design is achieved in that the spring element has a larger diameter than the width of the cylinder core recess provided for the tumbler in the direction of the cylinder core axis and that the spring element lies in an oblique bore which is penetrated by the cylinder core recess. It is also proposed that the Fe derelement by the first inserted into the cylinder core in particular the bottom of the tumbler can be compressed until the spring element snaps into the final position.

Besonders vorteilhaft ist bei allen Ausführungsformen, dass bei vielen Schlossarten ein Aussenzylinder sich erübrigt, da der Zylinderkern auch ohne Aussenzylinder gehandhabt werden kann.It is particularly advantageous in all embodiments that an outer cylinder is unnecessary in many types of lock, since the cylinder core can also be handled without an outer cylinder.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung bei einem Zylinderkern mit Plättchenzuhaltungen dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Fig. 1 einen Querschnitt durch einen Zylinderkern in Höhe einer Zuhaltung zu Beginn des Einschiebens der Zuhaltung,
  • Fig. 2 einen Schnitt nach Fig. 1 mit so tief eingeschobener Zuhaltung, dass das Federelement fast vollständig durch die Zuhaltung zusammengedrückt ist und
  • Fig. 3 einen Schnitt nach Fig. 1 mit so weit eingeschobener Zuhaltung, dass das Federelement in die Arbeitsstellung und damit in Anlage an die Anlagefläche der Zuhaltung gesprungen ist.
An embodiment of the invention is shown in the drawing for a cylinder core with plate tumblers and is described in more detail below. Show it
  • 1 shows a cross section through a cylinder core in the amount of a tumbler at the beginning of the insertion of the tumbler,
  • Fig. 2 shows a section of FIG. 1 with the tumbler inserted so deeply that the spring element is almost completely compressed by the tumbler and
  • 3 shows a section according to FIG. 1 with the tumbler pushed in so far that the spring element has jumped into the working position and thus into contact with the contact surface of the tumbler.

Ein Zylinderkern 1 eines Schliesszylinders weist schlitzförmige Querausnehmungen 2 auf, die diametral den Zylinderkern durchdringen und auf beiden Seiten des Zylinderkernmantels 3 offen sind. Zahl und Abmessungen der Querausnehmungen 2 entsprechen der Zahl und den Abmessungen plättchenförmiger Zuhaltungen 4 die in die Querausnehmungen 2 in radialer Richtung A einschiebbar sind. Durch den Zylinderkern 1 verläuft axial zur Zylinderkernachse 5 ein Schlüsselkanal 6, mit dem Öffnungen 7 gleicher Grösse in den Zuhaltungen 4 fluchten.A cylinder core 1 of a lock cylinder has slot-shaped transverse recesses 2 which penetrate the cylinder core diametrically and are open on both sides of the cylinder core shell 3. The number and dimensions of the transverse recesses 2 correspond to the number and the dimensions of plate-like tumblers 4 which can be inserted into the transverse recesses 2 in the radial direction A. A key channel 6, through which openings 7 of the same size in the tumblers 4 are aligned, runs axially through the cylinder core 1 to the cylinder core axis 5.

Die beiden Breitseiten jeder Querausnehmung 2 sind durch im Querschnitt kreissegmentförmige Ausnehmungen vertieft, die zusammen mit dem Zwischenraum der Ausnehmung 2 eine Bohrung 8 bilden, in der ein Federelement 9 in Form einer Schraubendruckfeder etwa gleichen Durchmessers einliegt.The two broad sides of each transverse recess 2 are recessed by recesses in the shape of a circular segment, which together with the intermediate space of the recess 2 form a bore 8 in which a spring element 9 in the form of a helical compression spring of approximately the same diameter lies.

Ausnehmung bzw. Bohrung 8 und damit auch das Federelement 9 liegen seitlich neben der Zuhaltung 4, wobei die Achse 10 des Federelements und der Bohrung 8 in einer zur Zylinderkernachse 5 rechtwinkligen Ebene liegt und mit der Mittelachse 11 der Zuhaltung und damit auch mit der Einführungsrichtung A einen Winkel von a = ca. 10 Grad bildet. Bei dieser Schräglage ist das erste Ende 12 der Feder näher der Zuhaltung als das zweite Ende 13.Recess or bore 8 and thus also the spring element 9 lie laterally next to the tumbler 4, the axis 10 of the spring element and the bore 8 lying in a plane perpendicular to the cylinder core axis 5 and with the central axis 11 of the tumbler and thus also with the insertion direction A. forms an angle of a = approx. 10 degrees. In this inclined position, the first end 12 of the spring is closer to the tumbler than the second end 13.

Die dem Federelement 9 zugewandte Schmalseite 14 der Zuhaltung 4 weist eine Ausnehmung 15 auf, in der das erste Ende 12 zumindest teilweise einliegt und dort die Anlagefläche 16 der Zuhaltung berührt. Durch Druck des Federelementes 9 auf diese Anlagefläche 16 ist die Zuhaltung 4 entgegen der Einführungsrichtung A federbeaufschlagt. Die Ausnehmung 15 in der Schmalseite 14 wird damit von zumindest einem Teil der Anlagefläche 16 und einer daran rechtwinklig anschliessenden Ausnehmungsseitenwand 17 gebildet, die in Richtung des zweiten Federendes in der Schmalseite 14 endet. Diese an die Ausnehmung 15 auf der der Anlagefläche 16 gegenüberliegenden Seite anschliessende Schmalseite 14 ist wie auch die gegenüberliegende Schmalseite 18 parallel zur Mittelachse 11 und damit auch parallel zur Einführungsrichtung. Hierbei schneidet eine gedachte Verlängerung der Schmalseite 14 im Bereich der Ausnehmung 15 das Federelement 9, so dass in diesem Bereich das Federelement eine Bewegung der Zuhaltung 4 entgegen der Einführungsrichtung A sperrt.The narrow side 14 of the tumbler 4 facing the spring element 9 has a recess 15 in which the first end 12 lies at least partially and there contacts the contact surface 16 of the tumbler. By pressing the spring element 9 on this contact surface 16, the tumbler 4 is spring-loaded against the direction of insertion A. The recess 15 in the narrow side 14 is thus formed by at least part of the contact surface 16 and a recess side wall 17 adjoining it at right angles, which ends in the direction of the second spring end in the narrow side 14. This narrow side 14 adjoining the recess 15 on the side opposite the contact surface 16 is, like the opposite narrow side 18, parallel to the central axis 11 and thus also parallel to the direction of insertion. Here, an imaginary extension of the narrow side 14 in the area of the recess 15 cuts the spring element 9, so that in this area the spring element blocks a movement of the tumbler 4 against the direction of insertion A.

Die für ein Sperren der Zuhaltung vorgesehene Ausnehmung 15 muss nicht unbedingt in einer der Schmalseiten 14, 18 vorgesehen werden, sondern kann auch in einer der beiden Flachseiten 19 eingebracht sein. Bei dieser zeichnerisch nicht dargestellten Version liegt die Federelementenachse in einer Ebene, die gleich oder parallel einer Ebene ist, die von der Zylinderkernachse und der Zuhaltungsmittelachse gebildet ist. Die Federelementenachse 10 bildet damit mit der Flachseite 19 den Winkel a. Ferner kann die Ausnehmung 15 in einer Verstärkung oder einem Vorsprung einer der Zuhaltungsseitenwände 14, 18, 19 eingebracht sein, so dass der die Sperrung bewirkende Abschnitt 14a der Zuhaltungswand von dem Abschnitt der Vorsprungsseitenwand gebildet ist, der dem zweiten Ende 13 des Federements 10 nahe ist, wie auch der Abschnitt 14a dem zweiten Ende 13 näher ist als dem ersten Ende 12.The recess 15 provided for locking the tumbler does not necessarily have to be provided in one of the narrow sides 14, 18, but can also be introduced in one of the two flat sides 19. In this version, not shown in the drawing, the spring element axis lies in a plane which is the same or parallel to a plane which is formed by the cylinder core axis and the tumbler center axis. The spring element axis 10 thus forms the angle a with the flat side 19. Furthermore, the recess 15 can be made in a reinforcement or a projection of one of the tumbler side walls 14, 18, 19, so that the blocking section 14a of the tumbler wall is formed by the portion of the projection sidewall which is close to the second end 13 of the spring element 10 , just as section 14a is closer to second end 13 than to first end 12.

Statt einer Schraubendruckfeder können die unterschiedlichsten Federelemente verwendet werden. So auch elastisches Kunststoffmaterial, das in Längsrichtung zusammendrückbar ist.A wide variety of spring elements can be used instead of a helical compression spring. So also elastic plastic material that can be compressed in the longitudinal direction.
