Definitions

  • the invention relates to a copy-protected profile flat key for cylinder locks with profiled vertical or horizontal key channel and milled according to a predetermined code according to the preamble of claim 1 and a key-lock combination according to claim 7.
  • the prior art also includes flat profile key for cylinder locks, where additionally in the profile area of the flat key before executing the notches or grooves for the code and the longitudinal profile at least one permanent magnetic section is used, the position of the permanent magnetic section on the longitudinal axis of the key profile in such a way it is chosen that remain in the formation of notches or milling lateral stabilization notch flanks.
  • a ferromagnetic part pin is located, which adjoins at least one profile cylinder bottom extending into non-ferromagnetic further part pin, under the action of the permanent magnetic portion of an imported, suitable flat key the ferromagnetic part pin can be moved into a release position.
  • the basic idea of the solution presented is that the key back of a profile flat key in his profile area has recesses extending at least in sections and perpendicular to the key longitudinal axis, the sequence of recesses resulting from top view resulting in a remaining web-like back, the shape of which is approximated by a sinusoidal function.
  • Such an additional coding option makes it difficult for a copy of the key even if a template and ensures the other a higher security against unauthorized unlocking a complementary cylinder lock.
  • the code variance can be determined by shifting the sine function on the back of the key, i. by changing the spatial position, by changing the amplitude and / or the frequency.
  • the depth of the recesses in the direction perpendicular to the key longitudinal axis can be changed.
  • Another way to obtain a variety of different codes is to stretch or compress and / or change the period of the sine function.
  • the recesses in the key back are preferably realized as a circular arc-shaped notches, so that keeps the manufacturing technology effort within limits.
  • the key lock combination with a flat key for cylinder locks with profiled vertical or horizontal key channel the flat key milled according to a predetermined code, starting from additional recesses in the back of the key, extending at least partially extending on the spine and extending perpendicular to the key longitudinal axis, wherein the result of the resulting recesses in plan view a remaining web-like Back results whose shape is approximated by a sine function.
  • the lock cylinder are then matched to these recesses additional locking elements for scanning the sine function coding located.
  • a profile flat key 1 which is known per se is assumed, which in the example shown is suitable for insertion into a cylinder lock with a vertical key channel.
  • This profile flat key has on its underside 2 per se known notch-shaped milled grooves for scanning cylindrical pins and has a longitudinal profile.
  • recesses 4 which run at least in sections and perpendicular to the key longitudinal axis, are introduced in the key back profile region in the keys 1 shown by way of example.
  • the sequence of recesses 4 resulting from top view results in a web-like back 5 whose shape can be approximated by a sinusoidal function (see right-hand part of the figure according to FIGS. 1 a to 1 c).
  • the code can be formed by changing the amplitude of the sine function in the region of the ridge-like back 5, but also by a variance of the frequency of the function.
  • the recesses 4 are realized substantially circular arc or semi-cylindrical by milling.
  • a coding is introduced on the profile flat keys according to the invention so that this coding on the back of the key, i. the narrow side of the key, forms a sinusoid.
  • This sinusoid can be arranged on the spine in different places, in different lengths, with different amplitudes and / or different frequencies.
  • the coding according to the invention can be introduced both alone and in addition to a conventional pin coding on the key.

Abstract

L'invention concerne une clé profilée plate incopiable pour serrures à cylindre qui présente un canal de clé profilé, vertical ou horizontal, et des fraisages qui correspondent à un code prédéterminé, ainsi qu'un profil longitudinal. Selon l'invention, le dos de la clé présente des découpes qui s'étendent au moins sur certaines parties de la région profilée et qui sont perpendiculaires à l'axe longitudinal de la clé. La succession des découpes dans une vue en plan fournit un dos sur lequel restent des nervures dont la forme peut être approchée par une fonction sinusoïdale.
