  • Figure 7 is similar to Figure 6, but shows the Lock position for the counter pin after the key has been removed.
  • FIG. 8 shows the tumbler pin enlarged along with a partial cut that shows the conical recess shows.
  • FIG. 9 shows the counter locking pin on an enlarged scale with a partial section showing the recess.
  • the key according to the invention is a toothed key 1, the one with a lock cylinder 2-3 with European format cooperates.
  • the key 1 when the key 1 is inserted is the distance between its theoretical center of rotation and its toothless edge 1a, i.e. the radius 4 the not toothed edge, smaller than the outer radius 5 of the rotor 3, the key in its non-toothed edge 1a at least a blind recess 7 with a relatively strong first compression spring 9 and a safety tumbler pin 8 has the protruding and depressed positions with respect to the blind recess 7 corresponding to the respective Cases of relaxation and compression of the first Spring 9 has.
  • this safety tumbler pin 8 in the radial direction and in contact with a safety locking pin 10 aligned in a seat of the Stator 2 used and by a second relatively weak Compression spring 11 is preloaded, this locking pin 10 protruding and retracting in this seat Positions corresponding to the case of expansion or contraction the second 11 and in contact between the Safety tumbler pin 8 and the safety tumbler pin 10 ingest through an opening 13 can, which is formed in an additional plate 12, which in the rotor 3 is inserted. The thickness of this additional plate 12 is equal to the difference between the radius 4 of the toothless Edge of the key and the outer radius 5 of the rotor.
  • the Safety tumbler pins 8 and 10 are in the longitudinal direction arranged in positions that are not the same as those of the tumbler-counter tumbler sets 14, 15 of the main tumbler or the castle secret of the castle.
  • the additional plate 12 shown in Figure 3 corresponds to a general one Configuration provided with five openings 13 however, in each case the number of safety tumbler pins match that in the toothless edge of the Key 1 are used.
  • this safety tumbler pin 8 ( Figure 8) a projecting head 8a and an end portion 8b for internal Lead, with this head 8a at its junction with the end part 8b a preferably conical recess 8c has a support for the respective end of the first Spring 9 results.
  • this head 8a at its junction with the end part 8b a preferably conical recess 8c has a support for the respective end of the first Spring 9 results.
