Definitions

  • the invention relates to a drilling protection for locking cylinders that within a Cylinder housing have a rotatable cylinder core and in which the mechanical Coding of the key by housing and core pins, as well as any additional ones lateral scanning elements, can be scanned.
  • Lock cylinders are protected differently against violent destruction.
  • protection against the axial pulling out of the cylinder core can be achieved by appropriate covers on the outer end face of the locking cylinder. These consist of hard materials such as special steels and cover the cylinder core to such an extent that an attack with a tool is not possible. These covers naturally also offer protection against drill attacks in the direction of the longitudinal axis of the locking cylinder or the cylinder core.
  • Lock cylinders of this type are not protected, however, against lateral drill attacks then when the drill more or less obliquely to the longitudinal axis of the cylinder housing is scheduled.
  • the object of the invention is therefore to provide a drilling protection for locking cylinders secures them against lateral drilling attempts.
  • the housing and / or core pins and the additional lateral scanning elements are surrounded by cage-like hard metal inserts arranged in the cylinder housing.
  • Such hard metal inserts are of course equivalent to inserts made of comparatively harder materials than the material from which the locking cylinder is made. An example of this would be a carbon fiber composite.
  • the hard metal inserts the cylinder and / or core pins and - if present - the lateral scanning elements, which are the actual target for Represent drilling attempts, surrounded by a cage.
  • closure-like here means an arrangement in which the lateral The distance between the inserts is so small that there is no drill bit between them fits or their shape and arrangement to a distraction - and thus a break - the drill tip leads.
  • the hard metal inserts are parallel to the longitudinal axis of the locking cylinder are arranged.
  • the hard metal inserts are like this aligned that they point at an acute angle to the end face of the locking cylinder.
  • the hard metal pins can have a round cross section, for example.
  • the lock cylinder housing is coincident with 8 and the one in it rotatably mounted cylinder core designated 9.
  • the core pins are 5 and Housing pin labeled 4.
  • the housing pins 4 act in a known manner with springs 6 together, which they press in the closed state over the core dividing line 7.
  • the inserts serving as protection against drilling are marked with 1 or 2. These run parallel to the longitudinal axis of the cylinder and are arranged such that they surround the housing pins and / or the core pins in a cage-like manner.
  • the hard metal pins 1, which are assigned to the core pins can be arranged directly in the cylinder core 9 in corresponding longitudinal bores.
  • the hard metal pins 1 or 2 should be dimensioned in diameter d such that on the one hand they have sufficient inherent strength and on the other hand the cage-like arrangement is possible, the distance x between the hard metal pins or inserts advantageously being less than 3 mm. It is also advantageous if a drilling or puncture protection, likewise in the form of a hard metal insert 3, is provided on the end side, facing both the inside of the locking cylinder and the outside.
  • FIG. 2 also shows the arrangement of an additional lateral scanning element - in Form of a locking bar - indicated.
