Abstract (en)

[origin: US6374654B1] Locking arrangement having a lock cylinder with an associated key (1), in particular a flat turning key, wherein a core (2) of the lock cylinder has a keyway (3) which is open in the direction of an end side of the cylinder, is provided with profile ribs/grooves and in the center thereof the vertex of a conical opening (4), which opens in the direction of the end side of the cylinder, is located. At an insertion end, the key (1) forms a tip (5) with flanks (6) in the form of arcuate lines. The tip (5) is formed by two arcuate lines (6), of which a point of intersection is located in a broad-side center (7) of the key, and a tangent angle (delta) at the point of intersection (5) is greater than the vertex angle (mu) of the cone opening (4), wherein the arcuate lines (6) have bevels (9), in the direction of the mutually opposite broad sides (8), having a bevel angle (omega) which is smaller than the vertex angle (mu) of the cone opening (4).

Abstract (de)

Die Erfindung betrifft eine Schließvorrichtung mit Schließzylinder mit zugehörigem Schlüssel (1), insbesondere Wende-Flachschlüssel, wobei der Zylinderkern (2) des Schließzylinders einen zur Zylinderstirnseite hin offenen, mit Profilrippen/-nuten versehenen Schlüsselkanal (3) besitzt, in dessen Mitte die Spitze einer zur Zylinderstirnseite sich öffnenden konischen Öffnung (4) liegt, wobei der Schlüssel (1) an seinem einsteckseitigen Ende eine Spitze (5) mit bogenlinienförmigen Flanken (6) ausbildet. Zur Erleichterung des Einführens des Schlüssels in den Schlüsselkanal ist vorgesehen, daß die Spitze (5) von zwei Bogenlinien (6) gebildet ist, deren Schnittpunkt in der Schlüsselbreitseitenmitte (7) liegt, und der Tangentenwinkel (Delta) im Schnittpunkt (5) größer ist als der Öffnungswinkel (My) der Konusöffnung (4), wobei die Bogenlinien (6) zu den sich gegenüberliegenden Breitseiten (8) Fasen (9) aufweisen mit einem Fasenwinkel (Omega), der kleiner ist als der Öffnungswinkel (My) der Konusöffnung (4). <IMAGE>
