Definitions

  • the system according to the present invention is particularly intended for application to a key of the type with a toothed shaft, said key having a smooth edge and a toothed edge with a series of recesses and protrusions, which the lock secret in connection with respective sets of main Form locking pins and main counter-locking pins which are spring-biased inside a corresponding unit consisting of a stator and rotor, which form a locking cylinder, preferably of a type with a European profile.
  • a suitable place for the insertion of such an additional anti-counterfeit tumbler pin is the toothless edge of the shaft of the key, because this is the point that has the greatest available material thickness without interference with the labyrinth-like longitudinal corrugation or the combination toothing of the toothed edge.
  • the novel proposed system provides an inventive solution that allows one or more additional tumbler pins to be inserted into the toothless edge of the key for non-copyability, thereby eliminating the problem discussed above.
  • This new system consists of the fact that the distance between the theoretical center of rotation and its toothless longitudinal edge, i.e. the radius of the toothless edge, is smaller than the outer radius of the rotor, and that at least one blind recess with a relatively strong one is located in this toothless edge first compression spring and a safety tumbler pin is formed, the projecting and retracted positions with respect to this blind recess according to the respective states of expansion and compression of the spring, that when the key is inserted in the correct combination, this safety tumbler pin is aligned radially and in contact with a safety tumbler pin which is inserted into a seat of the stator and is preloaded by a second, relatively weak compression spring, this counter-locking pin being able to assume projecting and retracted positions in this seat in accordance with the relaxed or compressed state of the second spring, and that the contact between the safety locking pin and the safety counter-locking pin takes place through an opening , which is present in an additional plate, which is inserted into the rotor, the thickness of this
  • this safety tumbler pin has a projecting head and an inner end part, this head at its connection point has a preferably conical recess with the end part, which provides support for the corresponding end of the first spring.
  • the safety counter locking pin also has a projecting head and an inner end part, this head having a recess at its connection point with the end part, which provides a support for the respective end of the second spring.
  • the key according to the invention is a toothed key 1, which interacts with a locking cylinder 2-3 with a European format.
  • one or more safety tumbler pins 8 are inserted into the shaft of the key 1 (two such tumbler pins are provided in FIG. 1, which are intended to cooperate with respective safety tumbler pins 10, which are inserted into the stator or the like Housing 2 of the locking cylinder 2-3 are inserted as soon as the key 1 has been inserted into the key channel of the rotor 3, which is produced by broaching.
  • Edge 1a has at least one blind recess 7 with a relatively strong first compression spring 9 and a safety tumbler pin 8 has, the projecting and depressed positions with respect to the blind recess 7 according to the respective cases of relaxation and compression of the first spring 9.
  • this safety tumbler pin 8 When the key 1 is inserted with the correct combination, this safety tumbler pin 8 is aligned in the radial direction and in contact with a safety tumbler pin 10, which is inserted into a seat of the stator 2 and preloaded by a second, relatively weak compression spring 1, whereby this counter locking pin 10 can protrude and retract positions in this seat in the event of expansion or contraction of the second 11 and in contact between the safety locking pin 8 and the safety locking pin 10 through an opening 13 formed in an additional plate 12 which is inserted into the rotor 3.
  • 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 arranged in the longitudinal direction at positions which do not coincide with those of the tumbler pin-counter tumbler pin sets 14, 15 of the main tumbler or the lock secret of the lock.
  • each security lock pin 10 is inserted through its corresponding opening 13 ( Figure 7) of the security plate 12, resulting in an additional rotation lock in addition to that by the Tumbler pin-tumbler pin sets 14-15 are caused, which are intended to form the main lock secret with respect to the toothed edge of the shaft of the key 1.
  • the additional plate 12 shown in FIG. 3 corresponds to a general configuration which is provided with five openings 13, but these in each case correspond to the number of safety tumbler pins which are inserted into the toothless edge of the key 1.
  • this safety tumbler pin 8 (FIG. 8) has a projecting head 8a and an end part 8b for internal guidance, this head 8a having a preferably conical recess 8c at its connection point with the end part 8b, which supports the respective end the first spring 9 results.
  • this head 8a having a preferably conical recess 8c at its connection point with the end part 8b, which supports the respective end the first spring 9 results.
  • the safety counter-locking pin 10 has a projecting head 10a and an end part 10b for internal guidance, this head 10a having a recess 10c at its connection point with the end part 10b, which provides a support for the corresponding end of the second spring 11 .
