Definitions

  • the invention relates to a lock cylinder.
  • the invention has for its object to further increase the security in such a lock cylinder and to simplify the manufacture.
  • a locking cylinder with a cylinder core rotatably mounted therein, which has a key channel into which a flat key can be inserted, which has profile codings on the side surfaces which interact with bodies which can be displaced in core bores and which, with the appropriate coding, enable the cylinder core to rotate , wherein the cylinder core has on its outer circumference at least one coaxial longitudinal opening that is open to the surrounding lock cylinder housing, the axial length of which is greater than the diameter of the core bore or the sum of the diameters of the core bores which open into the recess and wherein in the longitudinal recess Locking element is radially displaceable through the body or bodies between a position in which the locking element lies within the outer circumference of the cylinder core and a position in which the locking element extends over the parting plane cylinder core / cylinder the housing partially protrudes into a corresponding longitudinal recess in the cylinder housing, wherein in the cylinder core a radially extending first bore from
  • pin-shaped i.e. with a hemispherical surface or with a truncated cone, at the end facing the first body and a stop shoulder at the opposite end, it is achieved that this body must travel a short stroke to effect the locking function in the pin-shaped body to the locking element.
  • the profile coding on the side surface of the key moves a first body 3, which can be designed as a ball.
  • This body interacts with a second body which is designed in the form of a pin and which has been designated 7 'in the drawing.
  • the second body 7 'can have a hemispherical surface or a truncated cone at its end facing the first body 3.
  • a stop shoulder is provided which holds the body in the bore 9. This limits its upward movement.
  • this locking element With the appropriate coding on the key, this locking element is in a position retracted to such an extent that it does not protrude beyond the dividing line between the cylinder core and the cylinder housing. If, on the other hand, the coding is incorrect, the blocking element 8 'is displaced by the first body 3 via the second body 7 to such an extent that it projects into the recess 10 of the cylinder housing and thus prevents rotation of the cylinder core.
  • the key is designated 11 in the drawing.
  • the locking element itself is, seen in cross-section, designed so that two substantially perpendicular surfaces are provided and a third surface connects these two surfaces, which faces the recess 10 and is adapted in shape to the recess.
