<p>The invention relates to a locking arrangement having a lock cylinder with associated key (1), in particular a flat turning key, the cylinder core (2) of the lock cylinder having a keyway (3) which is open in the direction of the end face of the cylinder, is provided with profile ribs/grooves and in the centre of which the vertex of a conical opening (4), which opens in the direction of the end face of the cylinder, is located, the key (1), at its insertion end, defining a tip (5) with flanks (6) in the form of arcuate lines. In order to facilitate the introduction of the key into the keyway, it is provided that the tip (5) is defined by two arcuate lines (6), the point of intersection of which is located in the broad-side centre (7) of the key, and the tangent angle (delta) at the point of intersection (5) is greater than the vertex angle (My) of the cone opening (4), the arcuate lines (6) having bevels (9), in the direction of the mutually opposite broad sides (8), the bevels (9) having a bevel angle (omega) which is less than the vertex angle (My) of the cone opening (4).</p> |
