Embodiment Construction

[0034] as in Figures 1a to 1c As shown in , the invention is based on a conventional key 1 which cooperates with a cylinder 2 of a keyed locking system. A plurality of, in particular milled, control recesses are machined into the key tooth 3 of the key 1 for receiving sections of the associated locking pin 4 of the lock cylinder 2 .

[0035] Inside at least one of the control voids (see in particular Figure 1b ) is configured with a recess for receiving a profiled pin 5 inserted there, wherein the profiled pin has a profiled pin tip 6 with a predetermined contour.

[0036] At least the profiled pin tip 6 is provided with different hardness and / or wear properties relative to the material of the key tooth 3 and / or locking pin 4 .

[0037] The corresponding profiled pin tip 6 comes into contact with the side of the corresponding locking pin when the correct key has entered the lock cylinder, as in particular from Figure 1b and 1c As can be seen.

[0038] Figure 2a and ...

Abstract

The invention relates to a key for a lock cylinder of a key lock system, the key having a key head and a key bit, wherein the key bit has a plurality of control recesses for receiving an associated lock of the lock cylinder segment of the pin. According to the invention, a recess is formed inside at least one of the control recesses for receiving a profiled pin inserted therein, wherein the profiled pin has a profiled pin tip with a predetermined contour, and Furthermore, at least the profiled pin tip has different hardness properties and / or wear properties compared to the material of the key bit and / or locking pin.

Description

technical field [0001] The invention relates to a key for a lock cylinder of a key lock system, the key having a key head and a key bit, wherein the key bit has a plurality of control recesses for receiving an associated lock of the lock cylinder segment of the pin. Background technique [0002] A key for a rotary cylinder lock is previously known from DE 1093 253 B, wherein such a key has a longitudinal channel into which three longitudinally displaceable toothed stages are arranged transversely via tongue-shaped channels. When the key is pushed in, the tooth stage brings the locking pin arranged opposite the tooth stage plate into a starting position, in particular the so-called zero position. [0003] The locking system according to US 2013 / 0091910 A1 is based on a key, wherein a core pin can be attached to the key, which enables an additional encryption (kodierung, encryption). [0004] US 2013 / 0298621 A1 shows a key for closing systems, wherein the key has a movable e...
