Definitions

  • the invention relates to a cylinder lock with a rotatable in a housing, with a profiled key channel and cylinder pins protruding into this, provided locking cylinder, which cylinder pins stand in a position of the locking cylinder on spring-loaded housing pins and are conical at their other ends.
  • the aim of the invention is to avoid this disadvantage and to propose a cylinder lock of the type mentioned at the beginning, in which it is reliably prevented that all cylinder pins are grasped with a feeler tool.
  • this is achieved in that a gap is present between at least one side wall of the key channel and the lateral surfaces of the cylindrical pins, at least in their end region facing away from the housing pins.
  • the axes of the cylinder pins lie outside the central plane running in the longitudinal direction of the key channel.
  • the gap between the side wall of the key channel and the cylinder pins is at least 0.5 mm at least in sections.
  • the key channel runs in a Z-shaped cross-section at least in sections
  • the Z-shaped region of the key channel partially extends into the Plunges into the plane of the cylinder pins and the substantially cylindrical region of the cylinder pins extends beyond this region of the key channel in the rest position of the cylinder. This ensures that a probe tool inevitably in the gap between the wall of the Key channel and the cylinder pins penetrates and can only press the next cylinder pin laterally against the second wall of the key channel.
  • the lock according to the invention has a conventional housing 1, in which a lock cylinder 2 is rotatably held. Furthermore, the housing 1 has bores 3 which run perpendicular to the receptacle of the cylinder 2 and in which housing pins 4 and springs 5 which bias the cylinder 2 are held. Bores 6, in which cylindrical pins 7 are held, are arranged in the locking cylinder 2 perpendicular to its longitudinal axis. These cooperate in the usual way with the housing pins 4, which engage in the locking cylinder 2 and prevent its rotation if the cylinder pins are not brought into the correct position by a key 8. As can be seen from FIG.
  • the bores 6 of the cylinder 2 receiving the cylindrical pins 7 are offset from the central plane running in the longitudinal direction of the cylinder 2, the lateral boundary of the key channel 9 extending laterally to the boundaries of the bores 6 and thus of the cylindrical pins 7 . This ensures that a gap remains between the cylindrical pins 7 and the side wall or boundary.
  • a feeler tool 10 is inserted into the locking cylinder in order to bring the cylinder pins 7 into a position which enables the cylinder to be rotated, the feeler tool 10 slides into the gap between the side wall of the key channel 9 and the Cylinder pins 7 from, as shown in Fig. 4.
  • the possibility of being able to guide and move the stylus accordingly is severely restricted and it is no longer possible to depress the further cylindrical pins accordingly.
  • Fig. 4 it can also be seen that the cylindrical pins 7 are held with play in the bores 6, so that they are inclined when the feeler tool 10 slides, the feeler tool 10 coming into contact with the cylindrical outer surface of the cylindrical pins 7.
  • the cylindrical pins 7 extend with their cylindrical section beyond the Z-shaped profiled area of the key channel 9, the cylindrical pins abutting the end of the bores 6 in the rest position and the position of the cylindrical pin 7 shown in broken lines in FIG. 4 shows its depressed position.
  • the feeler tool slides into the gap between the side wall of the key channel 9 and the cylinder pins 7, thereby counteracting the cylinder pin the other wall is pressed and can no longer be pressed down.
