Description
Die Erfindung betrifft eine Sicherung von Zylinderschlössern gegen Anbohren mittels einer die Zylinderfront abdeckenden gehärteten Stahlplatte. Derartige Sicherungen' sind bereits bekannt, indes war bei diesen die Platte fest mit dem Zylinder verbunden. Diese Vorkehrung sicherte indes nur den Zylinder gegen den Angriff von Bohrwerkzeugen; der frei daliegende und leicht zugängliehe Schlüsseleinführungskanal von dem Drehzylinder war aber auch dadurch nicht geschützt, und es konnte immer noch durch Ansetzen von geeigneten Werkzeugen an dem Schlüsseleinführungskanal der Drehzylinderkern in seiner Drehrichtung unter Druck gesetzt werden, was das so gefürchtete Abtasten durch das Einführen eines Drahtes, mit dem die Zuhaltungsstifte" nacheinander eingeordnet wurden, erst ermöglichte, ao Dieser Nachteil wird nun nach der Erfindung dadurch beseitigt, daß die vor dem Schlüsseleinführungskanal befindliche Sicherungsscheibe in einer Ausnehmung an der Stirnfläche des Drehzylinderkerns drehbar gelagert ist.The invention relates to securing cylinder locks against drilling by means a hardened steel plate covering the cylinder front. Such fuses' are already known, but with these the plate was firmly connected to the cylinder. This precaution only secured the cylinder against attack by drilling tools; the exposed and easily accessible key insertion channel from the The rotating cylinder was not protected by this either, and it could still pass through Apply suitable tools to the key insertion channel of the rotary cylinder core be put under pressure in its direction of rotation, which is what the dreaded scanning by inserting a wire with which the tumbler pins "are arranged one after the other were, only made possible, ao This disadvantage is now after the invention thereby eliminated that the lock washer located in front of the key insertion channel is rotatably mounted in a recess on the end face of the rotary cylinder core.
Die Zeichnung veranschaulicht ein Beispiel des Erfindungsgegenstandes.The drawing illustrates an example of the subject matter of the invention.
Abb. ι zeigt den Zylinderdrehkern von einem Zylinderschloß mit Stiftzuhaltungen in der Draufsicht auf seine Stirnfläche mit der eingelagerten Sicherheitsscheibe,Fig. Ι shows the cylinder rotating core of a cylinder lock with pin tumblers in the top view of its end face with the embedded safety disc,
Abb. 2 einen Schnitt nach der Linie A-B der Abb. 1,Fig. 2 a section along the line AB in Fig. 1,
Abb. 3 die Draufsicht auf die Stirnfläche des Zylinderkerns mit der um 90 ° gedrehten Sicherheitsscheibe,Fig. 3 the top view of the end face of the cylinder core with the rotated by 90 ° Safety disc,
Abb. 4 die Sicherheitsscheibe in der Draufsicht und in der Seitenansicht,Fig. 4 the safety disc in plan view and in side view,
Abb. 5 ein vollständiges Zylinderschloß mit Drehzylinderkern mit eingelagerter Sicherheitsscheibe, Fig. 5 a complete cylinder lock with a rotating cylinder core with an embedded security disc,
Abb. 6 dasselbe mit verdrehter Sicherheitsscheibe. Fig. 6 the same with a twisted safety disc.
In dem drehbaren Zylinderkern 1 ist in einer Ausnehmung an der Stirnfläche derselben die Sicherheitsscheibe 2 drehbar gegenüber diesem Zylinderkern eingelagert. In diese Platte ist das jeweilige Profil des Schlüsselkanals eingearbeitet und deckt sich mit demselben (Abb. 1). Diese Anordnung der Platte sichert den drehbaren Zylinderdrehkern nicht nur gegen Anbohren, sondern verhindert auch, denselben in der Drehrichtung zwecks Abtastens der Zuhaltungen unter Druck zu setzen; außerdem verschließt sie auch den Schlüsseleinführungskanal, wenn sie gegenüber dem letzteren um 90 ° gedreht wird (Abb. 3 und 6). Ein Verschmutzen durch das Eindringen von Staub und Wasser u. dgl. wird dadurch fast verhindert.In the rotatable cylinder core 1 is in a recess on the end face of the same the safety disc 2 rotatably mounted with respect to this cylinder core. The respective profile of the Key channel incorporated and coincides with the same (Fig. 1). This arrangement the plate not only secures the rotating cylinder core against drilling, but also prevents the same in the direction of rotation for the purpose of scanning the tumblers below To put pressure; it also closes the key insertion channel when it is rotated by 90 ° compared to the latter (Fig. 3 and 6). A dirty one the penetration of dust and water and the like is almost prevented.
