Definitions

  • the invention relates to a lock cylinder with a cylinder core rotatably mounted therein according to the preamble of the claim.
  • Such a locking cylinder can be found, for example, in DE-A-3014183.
  • the invention has for its object the security of such Lock cylinder to further increase and simplify production.
  • the first body over the second body over the locking element keeps the parting plane pressed into the further longitudinal recess on the cylinder housing and the second body is located partially between the first body and the locking element, the geometric points of contact or lines of the second body and the locking element take self-locking angle, so that the locking element when turning second body can not push away and thus protrudes over the parting plane that the second Body is pin-shaped, with a hemisphere or a truncated cone on it the end facing the first body and a stop shoulder on the opposite End that the second core hole in the upper part is one of the stop shoulder of the second Body corresponding stop surface and that the locking element in cross section seen essentially square with a rounded corner, this being the further one Longitudinal recess is facing.
  • pin-shaped i.e. with a hemispherical surface or with a truncated cone on which the first Body facing end and a stop shoulder at the opposite end achieved that this body must travel a short stroke in order to perform the locking function to effect in the pin-shaped body to the locking element.
  • a first body 3 is moved by the profile coding on the side surface of the key, which can be designed as a ball.
  • This body interacts with a second body, which is pin-shaped and which was designated 7 'in the drawing.
  • the second body 7 ' is a hemispherical surface -or can have a truncated cone at its end facing the first body 3.
  • a stop shoulder is provided which engages the body in the Core hole 9 holds. This limits its upward movement.
  • This second body 7 ' cooperates with the locking element, which has been designated 8.
  • this locking element is in such a position retracted position that it does not have the parting planes between the cylinder core and Cylinder housing protrudes. If, on the other hand, the coding is incorrect, the first body 3 over the second body 7'- the locking element 8 moved so far that it in the Longitudinal recess 10 of the cylinder housing protrudes and thus a rotation of the Cylinder core hindered.
  • the key is designated 11 in the drawing.
  • the locking element itself is, in Cross section seen, designed so that two substantially perpendicular to each other standing surfaces are provided and a third surface connects these two surfaces, this facing the longitudinal recess 10 and the shape of the Longitudinal recess is adjusted.
