Abstract

Der Schließzylinder (10), insbesondere Profilzylinder, vorzugsweise für Türschlösser, ist versehen mit einem Gehäuse (12), das einen Aufnahmeraum (16) und mindestens eine in den Aufnahmeraum (16) mündende Aufnahmebohrung (26) aufweist, in welcher ein mit einer Feder (36) in Richtung auf den Aufnahmeraum (16) vorgespannter Gehäusestift (32) angeordnet ist. Ferner weist der Schließzylinder (10) einen Kern (14) auf, der drehbar in dem Aufnahmeraum (16) angeordnet ist und einen Schließkanal (18) für einen Schlüssel (20) und mindestens eine Aufnahmebohrung (26) für einen Kernstift (22) aufweist, welche sich zwischen dem Schließkanal (18) und der Außenseite (28) des Kerns (14) erstreckt und in einer vorgegebenen Drehstellung des Kerns (14) zwecks Freigabe desselben mit der mindestens einen Aufnahmebohrung (30) des Gehäuses (12) fluchtet. Der Gehäusestift (32) weist eine nadelförmige Verlängerung (38) an seinem dem Aufnahmeraum (16) abgewandten Ende (40) auf. Die nadelförmige Verlängerung (38) des Gehäusestiftes (32) ist von der Feder (36) umgeben. In der Aufnahmebohrung (30) des Gehäuses (12) ist ein Verriegelungselement (44) angeordnet, mit dem die nadelförmige Verlängerung (38) des Gehäusestiftes (32) zum Verriegeln desselben zusammenwirkt, wenn der Gehäusestift (32) in seiner Aufnahmebohrung (30) infolge einer Manipulation einem größeren Bewegungshub ausgesetzt ist als bei Verwendung des zum Freigeben des Kerns (14) innerhalb des Aufnahmeraums (16) vorgesehenen Schlüssels (20).

The lock cylinder (10), in particular profile cylinder, preferably for door locks, is provided with a housing (12) having a receiving space (16) and at least one in the receiving space (16) opening receiving bore (26), in which one with a spring (36) in the direction of the receiving space (16) biased housing pin (32) is arranged. Furthermore, the lock cylinder (10) has a core (14) which is rotatably arranged in the receiving space (16) and has a closing channel (18) for a key (20) and at least one receiving bore (26) for a core pin (22) which extends between the closing channel (18) and the outer side (28) of the core (14) and in a predetermined rotational position of the core (14) for the purpose of releasing the same with the at least one receiving bore (30) of the housing (12) is aligned. The housing pin (32) has a needle-shaped extension (38) at its end facing away from the receiving space (16) end (40). The needle-shaped extension (38) of the housing pin (32) is surrounded by the spring (36). In the receiving bore (30) of the housing (12) has a locking element (44) is arranged, with which the needle-shaped extension (38) of the housing pin (32) for locking cooperates, when the housing pin (32) in its receiving bore (30) due a manipulation is exposed to a greater movement stroke than when using the key (20) provided for releasing the core (14) within the receiving space (16).
