Definitions

  • the invention relates to a locking system with security reversible keys and associated cylinders according to the preamble of claim 1, and corresponding key blanks and security reversible key according to the preamble of claim 7.
  • Such devices are for example from the WO 01/77466 known.
  • Such a key is known with an insertion lock as an additional security element.
  • an additional control surface attached to the key, which prevents the insertion of a wrong key with an associated control pin on the cylinder entrance.
  • This control pin is longer than a coding silence and extends beyond the center plane of the key.
  • the control surface is formed on the key tip as a rising oblique inlet slope. It also extends beyond the median plane of the key and raises the control pin and pushes it out of the way. This control pin prevents the insertion of keys without the correct control surface.
  • These control surfaces can already be attached to the key blank and make it possible thus a blank protection. These oblique control surfaces are probably an additional complication, but they are still not difficult to copy. It is therefore very important to create a much higher copy protection with new methods.
  • a key system with security reversible keys which have at the key tip a horizontal block groove (BN) with a coded block depth.
  • BN horizontal block groove
  • a Blockzuiensshunt is attached to the rearmost coding position with a prolonged Blockzuzuiens, which prevents the Ganz-plugging a key with too low block groove.
  • This block-groove coding gives higher permutation capacities. Even such a horizontal block groove is still not difficult to copy.
  • the DE 201 05 519 U1 , the DE 100 31 972 A1 and the EP 1 048 804 A1 do not concern high-security reversible keys with at least two rows of tumblers on the flat sides, but only simple flat keys with a row of tumblers on a narrow side of the keys (spanner) with an additional lateral blocking element and with a permutation capacity which is many orders of magnitude smaller than that of the security device according to the invention. WendeBankel.
  • the concave recesses on the key tips act together with a convex shape on a counterpart in an associated cylinder, so that the concave recess rests flat on the convex shape on the counterpart with completely inserted key on the counterpart, and a blank or a key without this concave recess is locked out by the convex shape of the counterpart, ie a complete plugging is prevented.
  • These concave recesses are difficult to define and correspondingly very difficult is unauthorized copying thereof as well as the convexities in the cylinder.
  • the concave recesses can be made in a variety of different shape variants, so that thus a correspondingly higher permutation capacity can be achieved.
  • Fig. 1 illustrates the inventive locking system with a security reversible key S or a key blank S 'with at least two coding rows Ai on the flat sides and with an associated cylinder Za, Zb (shown in FIG Fig. 10 ) and with tumblers 3 (shown eg in Fig. 6 and 7a ), wherein by turning the cylinder a closing or switching function 9 is exercised.
  • the key tips 11 have a concave recess 10 which cooperates with a convex shape 20a, 20b on a displaceable counterpart 21a, 21b, so that the concave recess 10 rests flat on the counterpart when the key is fully inserted on the convex shape 20a, 20b and a blank or a key without this concave recess 10 through the convex molding 20 is locked out on the counterpart, ie a complete insertion is prevented and wherein the counterpart 21, a coupling part in the x direction in a closing or switching position is displaced.
  • the concave recess 10 starting from the key tip in the direction of the key axis x initially extending a first slope N1 and then a second inclination N2 to the key axis, wherein the second slope is greater than the first slope (N2> N1).
  • Fig. 1 and 10 show as an example a double cylinder Za, Zb, wherein by inserting a key with the correct concave recess 10, the counterpart 21 a, which is designed here as a sliding coupling part 22a, is inserted positively into a closing or switching element 23.
  • the closing or switching element 23 is rotated and thus causes a closing or switching function 9, for example a lock of a lock or an actuation of an electrical contact in a conventional manner.
  • Fig. 1 and 10 show the counterpart 21 in addition to the convex shape 20 also have a concave support portion 25, which corresponds to a convex shape of the key tip 11 adjacent to the concave recess 10.
  • the support surface can be increased.
  • the concave recesses 10 according to the invention on the key tip 11 and the associated convex formations 20 in the cylinder will be described in the following Fig. 2-5 further explained.
  • the Fig. 2a - d show on keys S or blanks S 'with a median plane 5 in the x-direction different forms of concave recesses 10.1 - 10.3 with a rounded portion 13, starting from a small first inclination N1 with respect to the x-axis, which in a much larger Tilt N2 passes.
  • These concave recesses are associated with convex formations 20.1 - 20.3 on the counterparts 21.1 - 21.3 in the cylinder, so that the concave recesses 10 rest on the convex formations 20 when the key is fully inserted.
  • a blank or key without the concave recess 10 abut with its ramp surface 35 at the key tip on the convex formation 20 and thereby blocked or stopped in a lockout distance a, so that the key not further (completely) inserted and the cylinder thus can not be turned.
  • These concave recesses 10 can be produced with a milling cutter 40 whose milling cutter axis 41.1 is perpendicular to the x-axis and which runs parallel to the y-axis. In this case, the cutter 40 is moved on a cutter path 42. The radius R of the milling cutter then also corresponds to the radius R of the rounded regions 13 of the concave recesses 10.
  • This concave recess 10.1 can be arranged only outside the run-up areas 7 of the tumblers 3, since the inclination N in the run-up area should be at most about 45 ° (see Fig. 6 ) or the casserole angle Nz of the tumblers 3 on the key tip 11 should correspond.
  • ramp surfaces 31 may be formed in a ramp area of tumblers ( Fig. 2d ).
  • the maximum inclination N2 can also be limited here by a block groove BN (see Fig. 7c ).

  • This recess 10.2 may be arranged in the ramp area 7, if the maximum inclination N of the concave recess is preferably at most 45 °.

  • the concave recess 10.11 has straight portions with slopes N1 and N2.
  • such concave recesses 10 may also have at least one inclined straight section in the x-direction in the section or at least three different straight and rounded sections or sections.
