Abstract

The invention relates to an anti-slip lock cylinder comprising a cylinder housing that has a cylinder core mounted rotatably therein. Radially extending bores which merge into each other in the bore base are provided in the cylinder core, one of these bores receiving a spring-mounted locking element and the other bore receiving a spring-mounted anti-slip pin. Running surfaces provided on the inner circumference of the cylinder housing are associated with the locking element and the anti-slip pin and influence the movement of the locking element and the anti-slip pin relative to each other.

Description

Antisc nipp-Schließzylinder  Antisc nipp lock cylinder
Die Erfindung betrifft einen Antischnipp - Schließzylinder, umfassend ein Zylindergehäuse mit einem drehbar darin gelagerten Zylinderkern. The invention relates to an anti - snipping lock cylinder, comprising a cylinder housing with a cylinder core rotatably mounted therein.
Die vorliegende Erfindung beschreibt die technische Lösung für einen Mechanismus, der die Rotation eines Zylinderkerns in einem Zylindergehäuse stoppt/blockiert. Dies stellt eine Sicherheitsfunktion eines Schließzylinders dar, die verhindert, dass durch The present invention describes the technical solution to a mechanism that stops / blocks the rotation of a cylinder core in a cylinder housing. This represents a safety function of a lock cylinder, which prevents by
schnelle Rotationsbewegungen, d.h. das„Schnippen" des Zylinderkerns, das Sperrelement durch seine Massenträgheit in seiner Freigabeposition verbleibt, damit es nicht in Eingriff mit seiner Sperrgeometrie im Gehäuse kommt und somit eine mehrtourige Rotation des Zylinderkerns ohne Berechtigung möglich ist. fast rotational movements, i. the "flipping" of the cylinder core, the blocking element remains in its release position by its inertia so that it does not interfere with its locking geometry in the housing and thus a multi-speed rotation of the cylinder core without authorization is possible.
Aufgabe der Erfindung ist es die Sicherheit bei einem Schließzylinder zu verbessern. The object of the invention is to improve the safety of a lock cylinder.
Gelöst wird diese Aufgabe erfindungsgemäß mit einem Antischnipp - Schließzylinder, umfassend ein Zylindergehäuse mit einem drehbar darin gelagerten Zylinderkern, der dadurch gekennzeichnet ist, This object is achieved according to the invention with an anti-snipping lock cylinder, comprising a cylinder housing with a cylinder core rotatably mounted therein, which is characterized
- dass radial verlaufende, im Bohrungsgrund ineinander übergehende, Bohrungen im Zylinderkern vorgesehen sind, von denen die eine Bohrung ein gefedertes Sperrelement und die andere Bohrung einen gefederten Schnippstift aufnimmt,  - That radially extending, merging in the bottom of the hole, holes are provided in the cylinder core, of which one hole receives a spring-loaded locking element and the other bore a spring-loaded snap-in pin,
- dass im Innenumfang des Zylindergehäuses eine Sperrgeometrie ausgebildet ist, die an einer definierten Umfangsposition des Innenumfangs des Zylindergehäuses, eine radiale Bewegung des Sperrelementes nach außen über die Trennebene  - That in the inner circumference of the cylinder housing a locking geometry is formed, which at a defined circumferential position of the inner circumference of the cylinder housing, a radial movement of the locking element to the outside over the parting plane
Zylindergehäuse/Zylinderkern in eine Ausnehmung im Zylindergehäuse zulässt, Cylinder housing / cylinder core into a recess in the cylinder housing permits,
- dass dem Schnippstift eine Schnippgeometrie Lauffläche am Innenumfang des  - that the Schnippstift a Schnippgeometrie running surface on the inner circumference of
Zylindergehäuses zugeordnet ist, mit einem radial nach innen weisenden Nocken, wobei der Nocken am Innenumfang bezogen auf die definierte Position der Ausnehmung der Sperrgeometrie so angeordnet ist, dass der Schnippstift von dem Nocken radial nach innen unter die Trennebene Zylindergehäuse/Zylinderkern bewegbar ist, wenn das Sperrelement nach außen über die Trennebene verschoben ist. Cylinder housing is assigned, with a radially inwardly facing cam, wherein the cam on the inner circumference with respect to the defined position of the recess of the Sperrgeometrie is arranged so that the Schnippstift of the cam is movable radially inwardly below the parting plane of the cylinder housing / cylinder core, if Locking element is shifted outwards over the parting plane.
In diesem Fall. geht es darum, dass durch schnelle Rotationsbewegungen - Schnippen des Zylinderkerns - das Sperrelement nicht seine vorgesehene Position beim passieren der Grundstellung einnehmen kann. Es ist nun möglich, ohne eine Berechtigung zu benötigen, den Zylinderkem des Schließzylinders beliebig oft zu rotieren und damit nachfolgende Elemente, wie zum Beispiel ein Einsteckschloss zu betätigen. In this case. It's about that through fast rotational movements - Flipping the cylinder core - the locking element can not assume its intended position when passing the basic position. It is now possible to require without authorization, the cylinder core of the lock cylinder to rotate as often as desired and thus to actuate subsequent elements, such as a mortise lock.
Grundsätzlich werden beim Öffnen eines Schließzylinders ein oder mehrere Sperrelemente bewegt, damit eine Rotation des Zylinderkerns ermöglicht wird. Die Bewegung des oder der Sperrelemente wird durch die Rotation des Zylinderkerns selbst initiiert, da sich diese an der Gehäuseinnengeometrie orientieren. Wird nun eine zweite Geometrie in das Gehäuse eingebracht, die komplementär zu der bisherigen ist, wird entweder Basically, one or more locking elements are moved when opening a lock cylinder, so that a rotation of the cylinder core is made possible. The movement of the locking element or elements is initiated by the rotation of the cylinder core itself, since these are based on the internal geometry of the housing. If now a second geometry is introduced into the housing, which is complementary to the previous one, either
- das Sperrelement durch seine konstruktive Ausführung selbst in die gewünschte Position gebracht (bei Betätigung mit üblicher/bestimmungsgemäßer Rotationsgeschwindigkeit) - The blocking element brought by its structural design even in the desired position (when operated at the usual / intended rotational speed)
- durch ein zusätzliches Element die gewünschte Position eines Sperrelements - By an additional element, the desired position of a locking element
erzwungen, bzw. die Rotation des Zylinderkerns blockiert, falls das Sperrelement sich nicht in der gewünschten Position befindet, im Fall einer stark erhöhten Rotationsgeschwindigkeit Schnippen des Zylinderkerns forced, or the rotation of the cylinder core blocks, if the blocking element is not in the desired position, in the case of a greatly increased rotational speed, flipping the cylinder core
Beide Lösungen führen dazu, dass bei einer schnellen Rotationsbewegung / Both solutions result in a fast rotation movement /
Schnippen des Kerns/, das oder die Sperrelemente selber oder das zusätzliche Flipping the core /, the one or more locking elements themselves or the additional
Element den Zylinderkern abbremsen, so dass alle Elemente, beim Passieren der Element brake the cylinder core, so that all elements, when passing the
Grundstellung in ihre vorgesehene Position bewegt werden. Basic position to be moved in their intended position.
Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen näher erläutert werden. Dabei zeigt: The invention will be explained in more detail with reference to the drawings. Showing:
Fig. 1 einen schematischen Querschnitt durch einen Schließzylinder in der Grundstellung, Fig. 2 einen verkleinerten Querschnitt mit beginnender Drehung des Zylinderkerns, 1 shows a schematic cross section through a lock cylinder in the basic position, FIG. 2 shows a reduced cross section with starting rotation of the cylinder core,
Fig. 3-6 die Rotation des Zylinderkems und Fig. 7 das Schnippen des Zylinderkerns. Fig. 3-6, the rotation of the cylinder core and Fig. 7, the flipping of the cylinder core.
Zunächst sei zur Erläuterung der verwendeten Begriffe angemerkt, dass die innere Umfangsfläche des Zylindergehäuses, also die Schnippgeometrie 3 oberhalb der First, to explain the terms used, it should be noted that the inner peripheral surface of the cylinder housing, that is, the Schnippgeometrie 3 above the
Trennebene zwischen Zylinderkern und Zylindergehäuse aufgrund der Konfiguration auch als mantelförmig bezeichnet werden kann. Parting plane between the cylinder core and cylinder housing due to the configuration can also be referred to as a jacket-shaped.
Bei beginnender Rotationsbewegung des Zylinderkerns 2 im Zylindergehäuse 1 , wird das Sperrelement 5 in seiner Bohrung im Zylinderkern mittels, der Sperrgeometrie 6 im At the beginning of rotational movement of the cylinder core 2 in the cylinder housing 1, the blocking element 5 is in its bore in the cylinder core by means of the locking geometry 6 in
Zylindergehäuse 1 radial in den Zylinderkern 2 bewegt (Figur 2 zu Figur 4). Cylinder housing 1 radially in the cylinder core 2 moves (Figure 2 to Figure 4).
An dieser Stelle sei angemerkt, dass hier zur Vereinfachung der Begriff„Bohrung" gewählt wurde. Streng genommen , ist nur der untere Teil, also der Abschnitt, der der It should be noted here that the term "hole" has been chosen here for the sake of simplicity. Strictly speaking, only the lower part, that is to say the section which is the
Zylinderkernmitte naheliegt, als Bohrung ausgebildet, während der Abschnitt, der der Trennebene zugeordnet ist, als Ausfräsung ausgeführt ist. Near center of the cylinder core, formed as a bore, while the portion which is assigned to the parting plane, is designed as a cutout.
Gleichzeitig wird der Schnippstift 7, dessen Bohrung sich im Zylinderkern 2 in die Bohrung des Sperrelementes 5 öffnet, durch die gespannte Schnippstiftfeder 8 gegen die Lauffläche oder Mantelfläche der Schnippgeometrie 3 gedrückt. Bei weiterer Drehung des At the same time, the snap-action pin 7, the bore of which opens in the cylinder core 2 into the bore of the blocking element 5, is pressed against the running surface or circumferential surface of the cutting geometry 3 by the tensioned snap-action spring 8. Upon further rotation of the
Zylinderkerns 2 bewegt sich der Schnippstift 7 (Figur 3 zu 4) aus der Bohrung des Cylinder core 2 moves the snap pin 7 (Figure 3 to 4) from the bore of the
Sperrelementes, so dass sich das Sperrelement - radial zurückgehend - unter oder hinter den Schnippstift legen kann ( Figur 4,5 und 6). Locking element, so that the locking element - radially going back - can lay under or behind the snipping pin (Figures 4,5 and 6).
Kommt es nun zu der Situation, dass der Zylinderkern 2 geschnippt wird (Figur 7), so verharrt das Sperrelement 5 zwar zunächst im Zylinderkern, jedoch wird der Schnippstift 7 durch den Nocken 4 der Schnippgeometrie in den Zylinderkern 2 gedrückt, wo dieser mit seinem unteren, vorzugsweise abgeschrägten, Ende auf das Sperrelement 5 stößt und dieses radial nach außen in die Ausnehmung 9 drückt (wie Figur 3), so dass damit die weitere Rotation des Zylinderkerns gebremst bzw. kurzfristig unterbunden wird. If it now comes to the situation that the cylinder core 2 is flipped (Figure 7), the locking element 5 remains indeed initially in the cylinder core, but the Schnippstift 7 is pressed by the cam 4 of Schnippgeometrie in the cylinder core 2, where this with its lower , preferably beveled, abuts the locking element 5 and pushes it radially outward into the recess 9 (as in FIG. 3), so that the further rotation of the cylinder core is thereby braked or prevented for a short time.
Vorzugsweise ist auch das untere Ende des Sperrelementes 5 abgeschrägt, und zwar komplementär zu der Abschrägung am Schnippstift 7 Preferably, the lower end of the locking element 5 is chamfered, namely complementary to the bevel on the snap pin. 7
Der Schutz des Zylinders gegen unberechtigte Betätigung wird durch diese Lösung verbessert. Ein Schnippen des Zylinderkerns über die Grundstellung hinweg wird unterbunden, womit ein mehrtouriges Bedienen des Schließzylinders erschwert bzw. verhindert wird. The protection of the cylinder against unauthorized operation is improved by this solution. A snap of the cylinder core over the basic position is away prevented, whereby a multi-speed operation of the lock cylinder is difficult or prevented.
