Lock Cylinder

摘要

A lock cylinder comprises a cylinder housing, a disk housing rotatably supported about a cylinder axis in the cylinder housing and a plurality of rotatably supported disk tumblers arranged along the cylinder axis in the disk housing, wherein each disk tumbler has a reception opening for a key, a blocking cut-out at the outer periphery for an at least partial reception of a blocking pin aligned in parallel with the cylinder axis and a fixing cut-out provided offset from the blocking cut-out at the outer periphery for an at least partial reception of a core pin aligned in parallel with the cylinder axis. The disk tumblers are rotatable from a starting position with a removed key into an end sorting position by a rotation of the introduced key in the latching direction, in which end sorting position the blocking cut-outs of all the disk tumblers are oriented in alignment with one another, viewed in the direction of the cylinder axis. The fixing cut-outs of all the disk tumblers are oriented in alignment with one another in the end sorting position, viewed in the direction of the cylinder axis. The lock cylinder is adapted such that, on a further rotation of the disk tumblers out of the end sorting position in the unlatching direction, the core pin first engages into the fixing cut-outs and the blocking pin only then engages into the blocking cut-outs.

1. A lock cylinder comprising
a cylinder housing (12), a disk housing (14) rotatably supported about a cylinder axis in the cylinder housing (12); a plurality of rotatably supported disk tumblers (16) arranged along the cylinder axis in the disk housing (14), wherein each disk tumbler (16) has a reception opening (18) for a key (24), a blocking cut-out (20) at the outer periphery for an at least partial reception of a blocking pin (22) aligned in parallel with the cylinder axis and, offset from the blocking cut-out (20), a fixing cut-out (44) provided at the outer periphery for an at least partial reception of a core pin (46) aligned in parallel with the cylinder axis; and wherein the disk tumblers (16) are rotatable from a starting position with a removed key (24) by a rotation of the introduced key (24) in an unlatching direction (D) into an end sorting position in which the blocking cut-outs (20) of all the disk tumblers (16) are oriented in alignment with one another, viewed in the direction of the cylinder axis; and wherein the fixing cut-outs (44) of all the disk tumblers (16) are oriented in alignment with one another in the direction of the cylinder axis in the end sorting position, with the lock cylinder (100) being adapted such that, on a further rotation of the disk tumblers (16) out of the end sorting position in the unlatching direction (D), the core pin (46) first engages into the fixing cut-outs (44) and the blocking pin (22) only then engages into the blocking cut-outs (20).
