Definitions
- the invention relates to a lock cylinder with a cylinder core rotatably mounted therein according to the preamble of the claim.
- Such a locking cylinder can be found, for example, in DE-A-3014183.
- the invention has for its object the security of such Lock cylinder to further increase and simplify production.
- the first body over the second body over the locking element keeps the parting plane pressed into the further longitudinal recess on the cylinder housing and the second body is located partially between the first body and the locking element, the geometric points of contact or lines of the second body and the locking element take self-locking angle, so that the locking element when turning second body can not push away and thus protrudes over the parting plane that the second Body is pin-shaped, with a hemisphere or a truncated cone on it the end facing the first body and a stop shoulder on the opposite End that the second core hole in the upper part is one of the stop shoulder of the second Body corresponding stop surface and that the locking element in cross section seen essentially square with a rounded corner, this being the further one Longitudinal recess is facing.
- pin-shaped i.e. with a hemispherical surface or with a truncated cone on which the first Body facing end and a stop shoulder at the opposite end achieved that this body must travel a short stroke in order to perform the locking function to effect in the pin-shaped body to the locking element.
- a first body 3 is moved by the profile coding on the side surface of the key, which can be designed as a ball.
- This body interacts with a second body, which is pin-shaped and which was designated 7 'in the drawing.
- the second body 7 ' is a hemispherical surface -or can have a truncated cone at its end facing the first body 3.
- a stop shoulder is provided which engages the body in the Core hole 9 holds. This limits its upward movement.
- This second body 7 ' cooperates with the locking element, which has been designated 8.
- this locking element is in such a position retracted position that it does not have the parting planes between the cylinder core and Cylinder housing protrudes. If, on the other hand, the coding is incorrect, the first body 3 over the second body 7'- the locking element 8 moved so far that it in the Longitudinal recess 10 of the cylinder housing protrudes and thus a rotation of the Cylinder core hindered.
- the key is designated 11 in the drawing.
- the locking element itself is, in Cross section seen, designed so that two substantially perpendicular to each other standing surfaces are provided and a third surface connects these two surfaces, this facing the longitudinal recess 10 and the shape of the Longitudinal recess is adjusted.

Description
Claims (1)
- Schließzylinder mit einem darin drehbar gelagerten Zylinderkern (1), der einen Schlüsselkanal (6) aufweist, in den ein Flachschlüssel (11) einführbar ist, der an den Seitenflächen Profilcodierungen aufweist, die mit in Kernbohrungen verschiebbaren Körpern zusammenwirken, die bei passender Codierung eine Drehung des Zylinderkernes ermöglichen, wobei der Zylinderkern an seinem Außenumfang mindestens eine zur Achse des Schließzylinders (1) achsparallel versetzt verlaufende, zum umgebenden Schließzylindergehäuse hin offene Längsausnehmung (4) aufweist, deren axiale Länge größer ist als der Durchmesser der Kernbohrung bzw. der Summe der Durchmesser der Kernbohrungen, die in die Längsausnehmung (4) münden und wobei in der Längsausnehmung (4) ein Sperrelement (8) radial durch den Körper oder die Körper verschiebbar ist zwischen einer Position, in der das Sperrelement (8) innerhalb des Außenumfanges des Zylinderkernes liegt und einer Position, bei der das Sperrelement (8) über die Trennebene Zylinderkern/Zylindergehäuse teilweise in eine entsprechende weitere Längsausnehmung (10) im Zylindergehäuse ragt,
dadurch gekennzeichnet,
daß in dem Zylinderkern (1) eine vom Schlüsselkanal (6) radial ausgehende erste Kernbohrung (2) für einen ersten Körper (3) vorgesehen ist, daß die Längsausnehmung (4) bezogen auf die Mittenlinie der ersten Kernbohrung (2) mittig hierzu oder dazu versetzt angeordnet ist, daß senkrecht zu der ersten Kernbohrung (2) und der Längsausnehmung (4) eine zweite Kernbohrung (5) vorgesehen ist, die sich im wesentlichen parallel zum Schlüsselkanal (6) erstreckt, und die sich in die erste Kernbohrung (2) und in die Längsausnehmung (4) öffnet und daß in der zweiten Kernbohrung (5) ein federbelasteter zweiter Körper (7') vorgesehen ist, der von dem ersten Körper (3) in der ersten Kernbohrung (2) und dem Sperrelement (8) gegen die Federkraft verschiebbar ist, wobei die Abmessungen und Lagen der Kernbohrungen bzw. der beiden Körper (3,7') und des Sperrelementes (8) so aufeinander abgestimmt sind, daß bei falsch codiertem, d.h. nicht passendem Schlüssel der erste Körper (3) über den zweiten Körper (7') das Sperrelement (8) über die Trennebene in die weitere Längsausnehmung (10) am Zylindergehäuse gedrückt hält und sich der zweite Körper (7') teilweise zwischen dem ersten Körper (3) und dem Sperrelement (8) befindet, wobei die geometrischen Berührungspunkte bzw. -Linien des zweiten Körpers (7') und des Sperrelementes (8) selbsthemmende Winkel einnehmen, so daß bei einem Drehversuch das Sperrelement (8) den zweiten Körper (7') nicht wegdrücken kann und damit über die Trennebene ragt, daß der zweite Körper (7') stiftförmig ausgebildet ist, mit einer Halbkugelfläche oder einem Kegelstumpf an seinem dem ersten Körper (3) zugewandten Ende und einer Anschlagschulter am gegenüberliegenden Ende, daß die zweite Kernbohrung (5) im oberen Teil eine der Anschlagschulter des zweiten Körpers (7') entsprechende Anschlagfläche aufweist und daß das Sperrelement (8) im Querschnitt gesehen im wesentlichen quadratisch ist mit einer abgerundeten Ecke, wobei diese der weiteren Längsausnehmung (1 0) zugewandt ist.
