Description

Die Erfindung betrifft einen Anbohrschutz für Schließzylinder, die innerhalb eines Zylindergehäuses einen drehbaren Zylinderkem aufweisen und bei denen die mechanische Codierung des Schlüssels durch Gehäuse - und Kernstifte, sowie eventueller zusätzliche seitliche Abtastelemente, abtastbar ist.The invention relates to a drilling protection for locking cylinders that within a Cylinder housing have a rotatable cylinder core and in which the mechanical Coding of the key by housing and core pins, as well as any additional ones lateral scanning elements, can be scanned.

Schließzylinder werden gegen gewaltsame Zerstörung verschieden geschützt.
So kann beispielsweise ein Schutz gegen das axiale Herausziehen des Zylinderkemes durch entsprechende Abdeckungen der äußeren Stimseite der Schließzylinder erreicht werden. Diese bestehen aus harten Materialien, wie besonderen Stählen und decken den Zylinderkem soweit flächig ab, dass ein Angriff mit einem Werkzeug nicht möglich ist. Diese Abdeckungen bieten natürlich auch einen Schutz gegen Bohrerangriffe in Richtung der Längsachse des Schließzylinders bzw. des Zylinderkemes.Lock cylinders are protected differently against violent destruction.
For example, protection against the axial pulling out of the cylinder core can be achieved by appropriate covers on the outer end face of the locking cylinder. These consist of hard materials such as special steels and cover the cylinder core to such an extent that an attack with a tool is not possible. These covers naturally also offer protection against drill attacks in the direction of the longitudinal axis of the locking cylinder or the cylinder core.

Nicht geschützt sind derartige Schließzylinder aber gegen seitliche Bohrerangriffe, also dann, wenn der Bohrer mehr oder weniger schräg zur Längsachse des Zylindergehäuses angesetzt wird.Lock cylinders of this type are not protected, however, against lateral drill attacks then when the drill more or less obliquely to the longitudinal axis of the cylinder housing is scheduled.

Aufgabe der Erfindung ist es daher, einen Anbohrschutz für Schließzylinder zu schaffen, der diese gegen seitliche Bohrungsversuche sichert.The object of the invention is therefore to provide a drilling protection for locking cylinders secures them against lateral drilling attempts.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, dass die Gehäuse - und/oder Kemstifte sowie die zusätzlichen seitlichen Abtastelemente von im Zylindergehäuse angeordneten Hartmetalleinlagen käfigartig umgeben sind.
Derartigen Hartmetalleinlagen gleichzusetzen sind natürlich Einlagen aus andere vergleichsweise härteren Materialien, als das Material aus denen der Schließzylinder besteht.
Ein Beispiel hierfür wäre ein Kohlenfaserverbundstoff.This object is achieved according to the invention in that the housing and / or core pins and the additional lateral scanning elements are surrounded by cage-like hard metal inserts arranged in the cylinder housing.
Such hard metal inserts are of course equivalent to inserts made of comparatively harder materials than the material from which the locking cylinder is made.
An example of this would be a carbon fiber composite.

Wesentlich ist, dass die Hartmetalleinlagen die Zylinder - und/oder Kemstifte und - falls vorhanden - die seitlichen Abtastelemente, die den eigentlichen Angriffspunkt für Anbohrversuche darstellen, käfigartig umgeben. It is essential that the hard metal inserts the cylinder and / or core pins and - if present - the lateral scanning elements, which are the actual target for Represent drilling attempts, surrounded by a cage.

Unter dem Begriff "käfigartig" wird hier eine Anordnung verstanden, bei der der seitliche Abstand der Einlagen von einander so gering ist, dass zwischen ihnen kein Bohrer hindurch passt oder aber deren Form und Anordnung zu einer Ablenkung - und damit einem Bruch - der Bohrerspitze führt.The term "cage-like" here means an arrangement in which the lateral The distance between the inserts is so small that there is no drill bit between them fits or their shape and arrangement to a distraction - and thus a break - the drill tip leads.

Vorteilhaft ist es, wenn die Hartmetalleinlagen parallel zur Längsachse des Schließzylinders angeordnet sind.It is advantageous if the hard metal inserts are parallel to the longitudinal axis of the locking cylinder are arranged.

Damit lässt sich die Herstellung wesentlich vereinfachen, und zwar besonders dann, wenn die Hartmetalleinlagen mit geringem Spiel in Bohrungen eingeschoben sind, die von der Schließzylinder-Innenseite ausgehen und im Abstand von der äußeren Stirnseite des Zylindergehäuses enden.This makes it much easier to manufacture, especially when the carbide inserts are inserted into the holes with little play, which are by the Assume the inside of the cylinder lock and at a distance from the outer face of the End of the cylinder housing.

Möglich ist auch, dass die Hartmetalleinlagen in einem Winkel zur Längsachse des Schließzylinders ausgerichtet sind.It is also possible that the hard metal inserts at an angle to the longitudinal axis of the Lock cylinder are aligned.

Gemäß einer weiteren Ausgestaltung der Erfindung, sind die Hartmetalleinlagen so ausgerichtet, dass sie spitzwinklig auf die Stimfläche des Schließzylinders weisen.According to a further embodiment of the invention, the hard metal inserts are like this aligned that they point at an acute angle to the end face of the locking cylinder.

Nach einer weiteren Ausgestaltung der Erfindung können im Zylindergehäuse zwischen dem Ende der Bohrungen und der äußeren Stirnseite des Schließzylinders senkrecht zu den Hartmetalleinlagen angeordnete Anbohrschutzstifte vorgesehen sein, so dass auch ein Angriff von der Stirnseite des Zylindergehäuses verhindert werden kann.According to a further embodiment of the invention, between the End of the holes and the outer face of the lock cylinder perpendicular to the Tungsten carbide inserts arranged anti-drilling pins can be provided, so that also a Attack from the front of the cylinder housing can be prevented.

Die Hartmetallstifte können beispielsweise einen runden Querschnitt aufweisen.The hard metal pins can have a round cross section, for example.

Vorteilhaft ist es schließlich noch, wenn die Hartmetalleinlagen gegen axiales Herausschlagen aus den Bohrungen durch Querstifte oder Sperrelemente gesichert sind.Finally, it is advantageous if the hard metal inserts against axial Knocked out of the holes are secured by cross pins or locking elements.

Die Erfindung soll nachfolgend an einem in den Zeichnungen dargestellten Ausführungsbeispiel erläutert werden.The invention is intended to be illustrated in the drawings Embodiment will be explained.

Dabei zeigt:

  • Fig. 1 schematisch einen Rundzylinder im Längsschnitt und einer Ansicht von der Zylinderinnenseite und
  • Fig. 2 entsprechende Ansichten eines Profilzylinders.
    • It shows:
  • Fig. 1 shows schematically a round cylinder in longitudinal section and a view from the inside of the cylinder and
  • Fig. 2 corresponding views of a profile cylinder.

    • In den Figuren sind übereinstimmend das Schließzylindergehäuse mit 8 und der darin drehbar gelagerte Zylinderkem mit 9 bezeichnet. Die Kemstifte sind mit 5 und die Gehäusestift mit 4 bezeichnet. Die Gehäusestifte 4 wirken in bekannter Weise mit Federn 6 zusammen, die diese im Schließzustand über die Kemtrennlinie 7 drücken.In the figures, the lock cylinder housing is coincident with 8 and the one in it rotatably mounted cylinder core designated 9. The core pins are 5 and Housing pin labeled 4. The housing pins 4 act in a known manner with springs 6 together, which they press in the closed state over the core dividing line 7.

    In beiden Fällen sind die als Anbohrschutz dienenden Einlagen, beispielsweise aus Hartmetall bestehen, mit 1 bzw. 2 gekennzeichnet. Diese verlaufen parallel zu der Zylinderlängsachse und sind so angeordnet, dass sie die Gehäusestifte und/ oder die Kemstifte käfigartig umgeben. Dabei können die Hartmetallstifte 1, die den Kernstiften zugeordnet sind, direkt im Zylinderkem 9 in entsprechenden Längsbohrungen angeordnet sein.
    Die Hartmetallstifte 1 bzw. 2 sollten im Durchmesser d so bemessen sein, dass sie einerseits eine ausreichende Eigenfestigkeit aufweisen und andererseits die käfigartige Anordnung möglich ist, wobei der Abstand x zwischen den Hartmetallstiften oder Einlagen zweckmäßig kleiner als 3 mm ist.
    Vorteilhaft ist es femer, wenn stimseitig sowohl an der Innenseite des Schließzylinders wie auch der Außenseite zugekehrt jeweils ein Anbohr- oder Durchschlagschutz, ebenfalls in Form einer Hartmetalleinlage 3 vorgesehen ist.    In both cases, the inserts serving as protection against drilling, for example made of hard metal, are marked with 1 or 2. These run parallel to the longitudinal axis of the cylinder and are arranged such that they surround the housing pins and / or the core pins in a cage-like manner. The hard metal pins 1, which are assigned to the core pins, can be arranged directly in the cylinder core 9 in corresponding longitudinal bores.
    The hard metal pins 1 or 2 should be dimensioned in diameter d such that on the one hand they have sufficient inherent strength and on the other hand the cage-like arrangement is possible, the distance x between the hard metal pins or inserts advantageously being less than 3 mm.
    It is also advantageous if a drilling or puncture protection, likewise in the form of a hard metal insert 3, is provided on the end side, facing both the inside of the locking cylinder and the outside.

    In der Figur 2 ist noch die Anordnung eines zusätzlichen seitlichen Abtastelementes - in Form einer Sperrleiste - angedeutet.FIG. 2 also shows the arrangement of an additional lateral scanning element - in Form of a locking bar - indicated.
