Abstract

Schlüssel, dessen Profilbereich mit einem negativ profilierten Schlüsselkanal (7) im drehbaren Zylinderkern (6) eines Profilzylinders korrespondiert und der im Profilbereich mit seitlichen konusförmigen Einsenkungen für jeweils zwei zusammengehörende Zuhaltungselemente (10,11) versehen ist, die aus jeweils einem Kernstift (10) und einem Gehäusestift (11) bestehen, und die praktisch in quer im Zylinderkern (6) liegenden Stiftbohrungen (9) geführt sind, wobei die Kernstifte (10) an ihren äußeren Enden (13) von den Gehäusestiften (11) beaufschlagt sind, welche ihrerseits in Richtung zum Profilbereich des eingesteckten Schlüssels federnd abgestützt sind, und wobei die Kernstifte (10) zur Ausrichtung der Zuhaltungselemente (10,11) in deren Freigabestellung mit ihren Kopfflächen (16) in die vorbestimmt so tiefen Einsenkungen des Profilbereichs des Schlüssels eintauchen, daß die anderen Enden (13) der Kernstifte (10) dann in der Mantelfläche des Zylinderkerns (6) liegen (Freigabestellung).Key whose profile area is profiled with a negative Key channel (7) in the rotatable cylinder core (6) Profile cylinder corresponds and that in the profile area with lateral conical depressions for two interlocking tumbler elements (10, 11) is provided, each consisting of a core pin (10) and a housing pin (11) exist, and practically in the transverse in the cylinder core (6) lying pin holes (9) are guided, the core pins (10) at their outer ends (13) from the housing pins (11) are applied, which in turn towards the Profile area of the inserted key resiliently supported and wherein the core pins (10) for aligning the tumbler elements (10,11) in their release position with their Head surfaces (16) in the predetermined deep depressions immerse the profile area of the key that the other Ends (13) of the core pins (10) then in the lateral surface of the Cylinder core (6) (release position).

Um den bekannten Schlüssel durch mechanische Bearbeitungsmaßnahmen so zu verbessern, daß die Kopiersicherheit erheblich verbessert ist und daß trotzdem der zugehörige Schließzylinder mit geringem fertigungstechnischem Aufwand herstellbar bleibt, wird er so ausgebildet, daß von wenigstens einer der Einsenkungen (14) ein vorbestimmter Teil der Umfangswand (15) vom Kopf (16) eines zugeordneten Kernstifts (10) beaufschlagt ist und die Position dieses Kernstifts (10) in seiner Stiftbohrung (9) so bestimmt, daß dieser seine Freigahestellung einnimmt.

Figure 00000001
In order to improve the known key by mechanical processing measures in such a way that the copy security is considerably improved and that the associated locking cylinder can still be manufactured with little manufacturing effort, it is designed so that at least one of the depressions (14) a predetermined part of the peripheral wall ( 15) is acted upon by the head (16) of an assigned core pin (10) and the position of this core pin (10) in its pin bore (9) is determined so that it assumes its release position.
