Definitions

  • the invention relates to key profiles for flat keys, which are formed on the side surfaces of the key shank and cooperate with a corresponding profiling in the keyway of a rotatably mounted in the lock cylinder housing cylinder core.
  • Key profiles for locking systems usually have different profile features in order to distribute shooting authorizations via a locking system. To be able to close with a parent key in all subordinate lock cylinder, it is necessary that the fixed profile features over all locking cylinders of this system are the same. By adding or omitting so-called variable profile features, there are situations in which the key fits into the closing channel or can not be inserted at all.
  • the object of the invention is to provide key profiles that offer improved copy protection.
  • the form factor f is a constant and is always 1.1. Furthermore, all profile features on the outer surface of a convex shape and the variable profile features on the inner surface of a concave shape. To give all profile features on the outside a convex shape is necessary to disguise the minimal profiling.
  • the maxima of the radii should furthermore be formed centrically to the respective profile feature. All profile features are constructed in such a way that they run symmetrically and at right angles to the imaginary key center plane relative to the profile central axis.
  • the radius is performed as a quarter circle with the center of the radius on the extended line of the fixed profile feature.
  • the value b denotes the distance between the transition of the variable profile feature into its radius, and the intersection of a line parallel to the key mid-plane, which is the extended line of the fixed profile feature below the profile angle ⁇ .
  • all profile features have a profile angle ⁇ of 3 °. This profile angle is also symmetrical to the profile center axis.
  • the cylinder core is designated 1 in the illustration.
  • variable profile features 3 enlarged in detail X
  • fixed profile features which are denoted by 4 and are shown enlarged in detail Y.
  • the fixed profile features 4 are characterized by straight profile surfaces on the profile base, wherein the inner surface of the profile base, so the surface which is located close to the key center plane is called. Accordingly, the outer surface of the wall of the keyway is assigned.
