Definitions

  • the invention relates to a lock cylinder with a key authorized to close, having a core of the lock cylinder which can be moved in a housing, having a locking channel arranged in the core for receiving the key, with at least one tumbler projecting into the lock channel for selectively blocking or releasing the movement of the core. with a guided in a bore of the core scanning body and a bore of the core facing recess in the housing and with a bore in the key for receiving a provided portion of the Abtast stressess.
  • Such a lock cylinder with a key is for example from the DE 20 2004 002 784 U1 known.
  • the scanning body is mounted in a core pin body and angled relative to this.
  • the core pin body is biased by a housing pin body in a direction pointing to the rotational axis of the core direction. Due to the angling of the scanning body relative to the core pin body, the tumbler is directed to a deviating from the axis of rotation of the core scanning in the closing channel.
  • the hole in the key is aligned with the direction of movement of the scanning body.
  • Various secrets can be generated by different depth holes and corresponding dimensions of the sample. For different locking secrets different length of sample are used and incorporated correspondingly deep holes in the key.
  • a disadvantage of this lock cylinder is that the space of such tumblers is limited. This leads to a small number of privacy secrets or to an ambiguous closing behavior of the key in the lock cylinder.
  • the invention is based on the problem to form a lock cylinder with a key of the type mentioned so on that it allows the generation of a high number of locking secrets with clear closing behavior even with limited space.
  • the lock cylinder and the key can be particularly easy to manufacture according to an advantageous embodiment of the invention, when the hole in the key is arranged perpendicular to a shaft of the key and the bore in the core inclined to the shaft of the key.
  • Another advantage of this design is that in addition to the depth, the position of the hole in the key varies with the locking secrets. Therefore, knowing the exact location and depth of the hole in the key is required for the copy of the key. This leads to a significant complication of copying the key.
  • the lock cylinder and the key according to another advantageous embodiment of the invention, the use of a plurality of tumblers and thus a variety of privacy secrets, when the hole is arranged in the key on a broadside.
  • the structural complexity for holding the Abtast stresses in its intended area can be kept particularly low according to another advantageous embodiment of the invention, when the bore is formed in the core as a stepped bore and the Abtast redesign is designed according to stages. By this design, no spring element for supporting the Abtast stressess is required.
  • the lock cylinder To further simplify the structure of the lock cylinder, it contributes according to another advantageous embodiment of the invention, when the key facing away from the end of the Abtast stressess facing directly the recess in the housing. Due to this design, the tumbler requires no housing pin. The recess can therefore be arranged in a thin-walled part of the housing.
  • FIG. 1 shows a lock cylinder 1 with a rotatable in a housing 2 core 3 with a series of Stiftzunnenen 4 for selectively blocking or releasing the movement of the core 3.
  • the core 3 has a lock channel 5 for insertion of a shaft 6 of a key 7 and for driving the Stiftzuiensen 4 on. Furthermore, the core 3 is connected to a cam 8.
  • FIG. 2 shows a sectional view through the lock cylinder 1 FIG. 1 along the line II - II. It can be seen that the lock cylinder 1 has at least one further controllable by the key 7 tumbler 9, via which the movement of the core 3 in the housing 2 can be blocked.
  • the key 7 is formed in the embodiment as a reversible key arranged on the shaft 6 broadsides 10, 11 and narrow sides 12, 13.
  • the pin tumblers 4 and the tumbler 9 are directed to the broad sides 10, 11 of the shaft 6 of the key 7.
  • the tumbler 9 has a in a bore 14 of the core 3 slidably guided and elongated designed Abtast Sciences 15.
  • the AbtastShime 15 protrudes with one end into a bore 16 in the key 7 and communicates with the other end of a recess 17 in a thin-walled portion of the housing 2 opposite. If the bore 16 in the key 7 is missing or if it is too shallow, the scanning body 15 would partially protrude into the recess 17 in the housing 2 and block the movement of the core 3.
  • the bore 14 in the core 3 is formed as a stepped bore and the Abtast emotions 15 designed in accordance with stages.
  • FIG. 3 shows greatly enlarged one in FIG. 2 With III marked portion of the lock cylinder 1 and the key 7.
  • the key 7 facing the end of the tumbler 9 can be seen.
  • An axis 18 of the Abtast stressess 15 is inclined at an angle ⁇ to the axis 19 of the bore 16 in the key 7.
  • the bore 16 in the key 7 is perpendicular to the shaft 6 of the key 7 and Bore 14 in the core 3 is arranged inclined to the shaft 6 of the key 7.
  • the axis 18 of the Abtast stressess 15 is perpendicular to a Drawing plane extending axis of rotation D directed.
  • dash-dotted lines a scanning 15 'with a touch point T' shown how he would rest on a key 7 without bore.
  • a measure a indicates the path of the Abtast stressess 15 between the two positions shown.
  • a measure b indicates the depth of the bore 16 in the key 7, which is required to allow movement of the Abtast stressess 15 by the dimension a.
  • FIG. 4 shows by way of illustration the ratios of the dimensions a and b. It can be seen here that the path of the scanning body 15 marked by the dimension a is greater than the depth of the bore 16 in the key 7 indicated by the dimension b. The dimension a is greater than the dimension b, resulting in a particularly clear closing behavior and generate a plurality of locking secrets of tumbler 9.
