Description

Die Erfindung betrifft eine Zuhaltung nach dem Oberbegriff des unabhängigen Patentanspruchs 1.The invention relates to a tumbler according to the preamble of independent patent claim 1.

Drehzylinderschlösser mit Zuhaltungen dieser Art sind all­gemein bekannt und weisen in der Regel einen hohen Sicher­heitswert auf. Es sind aber Oeffnungsmethoden entwickelt worden, mit denen diese Drehzylinderschlösser ohne Schlüs­sel und ohne äussere Beschädigung an den Schlössern geöff­net werden können. Eine Spurensicherung ist bei diesen Oeffnungsmethoden in der Regel nicht möglich.Rotary cylinder locks with tumblers of this type are generally known and generally have a high security value. However, opening methods have been developed with which these rotary cylinder locks can be opened without a key and without external damage to the locks. With these opening methods it is generally not possible to secure evidence.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Dreh­zylinderschloss der genannten Art zu schaffen, bei dem die­se Oeffnungsmethoden unwirksam sind und das dennoch ein­wandfrei funktioniert und kostengünstig herstellbar ist.The invention is based on the object of creating a rotary cylinder lock of the type mentioned, in which these opening methods are ineffective and which nevertheless functions properly and can be produced inexpensively.

Die Aufgabe wird erfindungsgemäss nach dem Kennzeichen des Patentanspruchs 1 gelöst.The object is achieved according to the characterizing part of patent claim 1.

Die Erfindung hat den weiteren Vorteil, dass abgesehen vom Kernstift das Drehzylinderschloss wie üblich ausgebildet werden kann. Es können somit die bekannten Drehzylinder­schlösser für Flach- oder Zackenschlüssel verwendet werden. Der Kernstift kann in einfacher Weise hergestellt werden und eignet sich deshalb auch zum Ausrüsten von se­rienmässig hergestellten Drehzylinderschlössern.The invention has the further advantage that, apart from the core pin, the rotary cylinder lock can be designed as usual. The known rotary cylinder locks for flat or wrenches can thus be used. The core pin can be manufactured in a simple manner are and is therefore also suitable for equipping series-produced rotary cylinder locks.

Durch die Fertigung der Spitze des Kernstifts als separa­ter Teil, ist es möglich diese aus einem Hartmetallwerk­stoff herzustellen, so dass das Drehzylinderschloss aufbohr­sicherer ist und sich die Steuerfläche auch bei häufigem Gebrauch nicht abnützt.By manufacturing the tip of the core pin as a separate part, it is possible to manufacture it from a hard metal material, so that the rotary cylinder lock is more secure against drilling and the control surface does not wear out even with frequent use.

Die Weiterbildung der Erfindung gemäss Anspruch 7 hat den Vorteil, dass zusätzlich auch Oeffnungsmethoden unwirksam sind, bei denen versucht wird den wirksamen Teil der Zu­haltung auszumessen.The development of the invention according to claim 7 has the advantage that, in addition, opening methods are also ineffective, in which an attempt is made to measure the effective part of the guard locking.

Weitere vorteilhafte Ausbildungen gehen aus den übrigen abhängigen Ansprüchen hervor.Further advantageous developments emerge from the remaining dependent claims.

Ausführungsbeispiele der Erfindung werden nachfolgend an­hand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 einen Längsschnitt durch einen Kernstift,
  • Fig. 2 einen Querschnitt durch einen Teil eines Drehzylinderschlosses, wobei die Zuhaltung teilweise in Ansicht gezeigt ist,
  • Fig. 3a und 3b je einen Querschnitt durch einen Teil eines Dreh­zylinderschlosses mit einer Zuhaltung nach einer weiteren Ausführung, wobei diese teilweise in An­sicht dargestellt ist.
  • Fig. 4 einen Längsschnitt durch eine weitere Ausführung einer Zuhaltung.
Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:
  • 1 shows a longitudinal section through a core pin,
  • 2 shows a cross section through part of a rotary cylinder lock, the tumbler being partially shown in view,
  • 3a and 3b each show a cross section through part of a rotary cylinder lock with a tumbler according to a further embodiment, this being partially shown in view.
  • Fig. 4 shows a longitudinal section through a further embodiment of a tumbler.

Der in Fig. 2 teilweise dargestellte Schlosszylinder weist in bekannter Weise ein ruhendes Zylindergehäuse 12 auf, das in einer zylindrischen Hülse 11 steckt und in dem drehbar ein Zylinderkern 13 angeordnet ist. Das Zylindergehäuse 12 und der Zylinderkern 13 weisen radiale Bohrungen 17 auf, in denen federbelastete zweiteilige Zuhaltungen verschiebbar gelagert sind. Im Gehäuseteil der Bohrung 17 befindet sich einen Druckfeder 16, die sich gegen die Hülse 11 abstützt und die mit Vorspannung auf einen Gehäusestift 15 drückt, der seinerseits einen Kernstift 10 radial nach innen gegen einen in den Schlüsselkanal 14 einzuführenden Schlüssel drückt.The lock cylinder partially shown in FIG. 2 has, in a known manner, a stationary cylinder housing 12 which is inserted in a cylindrical sleeve 11 and in which a cylinder core 13 is rotatably arranged. The cylinder housing 12 and the cylinder core 13 have radial bores 17 in which spring-loaded two-part tumblers are slidably mounted. In the housing part of the bore 17 there is a compression spring 16 which is supported against the sleeve 11 and which presses with pretension on a housing pin 15 which in turn presses a core pin 10 radially inwards against a key to be inserted into the key channel 14.

Der Kernstift 10 weist einen Körper 1 mit einer axialen Stufenbohrung 27 auf, in der ein entsprechend stufenförmig ausgebildeter Sperrstift 24 verschiebbar gelagert ist.The core pin 10 has a body 1 with an axial stepped bore 27, in which a correspondingly stepped locking pin 24 is slidably mounted.

Der Kernstift 10 weist eine separat gefertigte Spitze 3 mit einem Kopf 3b und Verbindungsteil 3a auf, die mit Fest­sitz in die Bohrung 27 eingesetzt ist. Die Spitze 3 kann aus einem anderen Werkstoff als die übrigen Teile des Kern­stifts gefertigt sein. Vorzugsweise ist die Spitze aus ei­nem aufbohrsicheren und abriebfesten Hartstoff beispiels­weise einem geeigneten Hartmetallwerkstoff gefertigt.The core pin 10 has a separately manufactured tip 3 with a head 3b and connecting part 3a, which is inserted with a firm fit into the bore 27. The tip 3 can be made of a different material than the other parts of the core pin. The tip is preferably made of a drill-resistant and abrasion-resistant hard material, for example a suitable hard metal material.

In der Stufenbohrung 27 befindet sich eine Druckfeder 25, die sich gegen den Spitz 3 abstützt und mit Vorspannung auf den Sperrstift 24 drückt. Der Sperrstift 24 ist so aus­gebildet, dass er aus der Bohrung 27 herausragt, wenn er, wie in Fig. 1 gezeigt, nur von der Druckfeder 25 belastet ist. Ist der Kernstift 10 in den Drehzylinder eingesetzt, wirkt der Druckfeder 25 der stärkeren Feder 16 entgegen und hält den Sperrstift 24 in der in Fig. 2 gezeigten versenk­ten Lage. Infolge der Spannung der Druckfeder 25 drückt der Sperrstift 24 gegen den Gehäusestift 15 ohne diesen jedoch aus seiner den Drehzylinder verriegelnden Position zu bewegen.In the stepped bore 27 there is a compression spring 25, which is supported against the point 3 and presses with pretension on the locking pin 24. The locking pin 24 is designed such that it protrudes from the bore 27 when, as shown in FIG. 1, it is only loaded by the compression spring 25. If the core pin 10 is inserted into the rotary cylinder, the compression spring 25 counteracts the stronger spring 16 and holds the locking pin 24 in the recessed position shown in FIG. 2. As a result of the tension of the compression spring 25, the locking pin 24 presses against the housing pin 15 without, however, moving it out of its position locking the rotary cylinder.

Die Wirkungsweise der Zuhaltung im Fall eins unbefugten Oeffnungsversuchs soll anhand der Fig. 3b kurz erläutert werden. Der Gehäusestift 15 ist hier durch eine bekannte Oeffnungsmethode kurzzeitig in eine entriegelte Position bewegt worden, wobei der Kernstift 30 in seiner ursprüng­lichen Position verharrt. Die beiden Zuhaltungsstifte sind beispielsweise auseinandergesprengt worden. Gelingt dies bei einem üblichen Drehzylinderschloss bei allen Zuhaltungen gleichzeitig, so kann der Zylinderkern 13 in einem kurzen Zeitintervall gedreht und das Schloss geöffnet werden. Dies gelingt bei der erfindungsgemässen Zuhaltung jedoch nicht, da der Sperrstift 24 durch den Druck der Feder 25 dem sich radial nach aussen bewegenden Gehäusestift 15 im wesentlichen verzögerungsfrei folgt. Sobald der Gehäuse­stift 15 die Scherfläche 32 verlässt, greift der Sperr­stift 24 über diese hinweg und verriegelt den Drehzylin­der. Der Sperrstift 24 verharrt in seiner verriegelnden Position, bis er vom Gehäusestift 15 wieder in seine ur­sprüngliche Position (Fig. 3a) gedrückt wird.The mode of operation of the guard locking in the event of an unauthorized opening attempt is to be briefly explained with reference to FIG. 3b. The housing pin 15 has been briefly moved into an unlocked position by a known opening method, the core pin 30 remaining in its original position. For example, the two tumbler pins have been blown apart. If this is possible with a conventional rotary cylinder lock for all tumblers at the same time, the cylinder core 13 can be rotated in a short time interval and the lock can be opened. However, this does not succeed with the tumbler according to the invention, since the locking pin 24 follows the housing pin 15, which moves radially outward, essentially without delay due to the pressure of the spring 25. As soon as the housing pin 15 leaves the shear surface 32, the locking pin 24 reaches over it and locks the rotary cylinder. The locking pin 24 remains in its locking position until it is pressed back into its original position (FIG. 3a) by the housing pin 15.

Neben der genannten Oeffnungsmethode gibt es auch solche, bei denen versucht wird, den wirksamen Teil der Zuhaltung auszumessen. Um auch diese Oeffnungsmethoden unwirksam zu machen, ist ein Kernstift 30 vorgesehen. Wie die Fig. 3a und 3b zeigen, weist dieser zusätzlich zum Sperrstift 24 ein hülsenförmiges Schiebeelement 31 auf, das in Längs­richtung verschiebbar auf dem Stiftkörper 1 und in der Bohrung 17 im Zylinderkern 13 gelagert ist. Das Schiebe­element 31 ist entsprechend der Bohrung im Zylinderkern 13 stufenförmig abgesenkt. Das Schiebeelement 31 erfährt demnach radial nach innen in der Bohrung 17 einen Anschlag. Ebenfalls entsprechend stufenförmig ausgebildet ist der Stiftkörper 1, der radial nach innen an der stufenförmigen Innenfläche des Schiebeelementes 31 einen Anschlag erfährt.In addition to the opening method mentioned, there are also attempts to measure the effective part of the guard locking. To make these opening methods ineffective, a core pin 30 is provided. As shown in FIGS. 3a and 3b, this has, in addition to the locking pin 24, a sleeve-shaped sliding element 31 which is displaceable in the longitudinal direction on the pin body 1 and in the bore 17 in the cylinder core 13. The sliding element 31 is lowered in a step-like manner in accordance with the bore in the cylinder core 13. The sliding element 31 accordingly experiences a stop radially inward in the bore 17. Also correspondingly step-shaped is the pin body 1, which experiences a stop radially inward on the step-shaped inner surface of the sliding element 31.

Bei der in Fig. 3a gezeigten Position des Schiebeelementes 31 besteht zwischen diesem und der Spitze 3 eine Lücke 18, die vorzugsweise etwa 0,4 mm breit ist. Bei den genannten Oeffnungsmethoden bleibt der wirksame Teil der Zuhaltung radial nach aussen immer beweglich und kann deshalb nicht ausgemessen werden. Ebenso scheitern Oeffnungsmethoden, die mit Hilfe von Andrückversuchen arbeiten, da auch hier der wirksame Teil der Zuhaltung nicht fixierbar ist. In der Lücke 18 kann eine hier nicht dargestellte Druckfeder an geordnet sein, welche sicherstellt, dass beim Verschieben des Kernstifts die Lücke 18 erhalten bleibt.In the position of the sliding element 31 shown in FIG. 3a, there is a gap 18 between the latter and the tip 3, which is preferably about 0.4 mm wide. With the opening methods mentioned, the effective part of the tumbler always remains movable radially outwards and therefore cannot be measured. Opening methods that work with the help of pressure attempts also fail because here too the effective part of the guard locking cannot be fixed. In the gap 18, a compression spring, not shown here, can be arranged, which ensures that the gap 18 is retained when the core pin is moved.

Eine weitere und besonders kostengünstige Ausführung einer erfindungsgemässen Zuhaltung mit einem Kernstift 40 ist in Fig. 4 dargestellt. Der Kernstift 40 weist einen Körper 46 mit einer zylindrischen Sackbohrung 42 auf, in welche ein ebenfalls zylindrischer Sperrstift 41 eingesetzt ist. Der Gehäusestift 15, gegen den der Sperrstift 41 unter dem Druck einer Feder 45 anliegt, ist wie oben beschrieben ausgebil­det. Der hier dargestellte Körper 46 ist an der Spitze ab­gerundet und für ein Drehzylinderschloss mit Zackenschlüssel (Yale-Zylinder) vorgesehen.Another and particularly inexpensive embodiment of a tumbler according to the invention with a core pin 40 is shown in FIG. 4. The core pin 40 has a body 46 with a cylindrical blind bore 42, into which a likewise cylindrical locking pin 41 is inserted. The housing pin 15, against which the locking pin 41 abuts under the pressure of a spring 45, is designed as described above. The body 46 shown here is rounded at the tip and is intended for a rotary cylinder lock with a wrench (Yale cylinder).

Die Kernstifte 10 und 30 können in übliche Drehzylinder eingesetzt werden und arbeiten bei einer Betätigung mit dem zugeordneten Schlüssel in gleicher Weise wie die be­kannten Kernstifte.The core pins 10 and 30 can be inserted into conventional rotary cylinders and work in the same way as the known core pins when actuated with the assigned key.
