Definitions

  • the present invention refers to a high-security closing device and unlocking procedure.
  • the device according to the present finding comprises a lock and a key which collaborate to take the aforementioned lock into an open or closed configuration.
  • locks comprise a stator equipped with a cylindrical hole in which a rotor which has a slot for the insertion of the key is rotatably inserted.
  • the stator and the rotor have a plurality of transversal holes where some counterpegs and pegs, respectively, are housed which collaborate with the key to open or close the lock (standard or direct lock).
  • the key is equipped with mechanical encryption, defined by protrusions or undercuts of its own profile.
  • the key has mechanical encryption defined by a plurality of indentations realised on its own flat part, so that the pegs inserting into such indentations take the lock into open or closed configuration.
  • a lock of the passive type has a stator and rotor with the same structure as those used in locks of the direct type, with the difference that the transversal holes of the stator do not contain the counterpegs, but are left empty.
  • EP-A-0 431 550, FR-A-2 762 345 and US-B1-6 257 033 disclose a high security closing device according to the preamble of claim 1.
  • the technical task proposed of the present invention is, therefore, that of realising a high-security closing device and unlocking procedure which allow the aforementioned technical drawbacks of the prior art to be eliminated.
  • a purpose of the invention is that of realising a device in which the reproduction of the key is very difficult, so as to limit the risk of them being wrongfully duplicated.
  • Another purpose of the invention is that of realising a device in which the lock and the key have a very high number of possible combinations, without it being necessary to increase the number of pegs and, therefore, the complexity of the lock and of the key.
  • a further purpose of the present invention is that of realising a device which can only be taken into open configuration when the encryption of the key is correct.
  • the last but not least purpose of the present invention is that of realising a high-security closing device and unlocking procedure which are substantially cost-effective.
  • the present finding also regards a high-security unlocking procedure of a closing device comprising a key and a lock, according to claim 4.
  • a high-security closing device which comprises a lock, wholly indicated with reference numeral 1, and a key, wholly indicated with reference numeral 2.
  • the lock 1 comprises a stator 3 which carries a plurality of counterpegs 4 slidably inserted in seats 5, capable of moving against springs and by the action of springs 6.
  • the lock comprises, moreover, a rotor 7 which carries a plurality of pegs 8, which can be aligned with the counterpegs 4 in an open configuration of the lock and which has a slot 9 where the key 2 can be housed.
  • the key 2 has at least one pin 10 (in the embodiment shown in the attached figures the key has two pegs to be reversible) which can move between a withdrawn portion and a protruding position.
  • the rotor 7 comprises actuation means 12 of the pin 10 between the withdrawn position and the protruding position.
  • the actuation means 12 comprise an element of the rotor 7 which protrudes inside the slot 9; correspondingly, the key 2 has a groove 13 connected to a seat 14 of the pin 10, for the actuation of the pin 10 when the protruding element 13 inserts into the groove 13.
  • the seat 14 is connected to the groove 13 in correspondence with a portion of its own base; another base portion 15 of the seat 14, on the other hand, is blind.
  • the blind portion 15 of the seat 14 is left out.
  • the seat 14 has, moreover, a raised radial portion 16 which partially closes its front opening.
  • annular portion is realised, for example, by deforming the front edge of the seat 14 or else, in another embodiment, by connecting an annular element to the end of the seat 14.
  • the pin 10 has an enlarged head inserted into an enlarged portion of the seat 14 and the enlarged head is substantially frustum of cone-shaped.
  • the pin 10 is misaligned with respect to the conventional pegs 17 to allow the insertion of the key 2 into the slot 9.
  • the security peg 11 is aligned with the conventional pegs 17, so as to be able to use the conventional locks and, since the pin 10 is misaligned with respect to the conventional pegs 17, the security peg 11 has a flattened end portion to collaborate with the pin 10.
  • the end portion of the security peg 11 is cylindrical with an end suitable for collaborating, going into contact in correspondence with its peripheral portion, with the pin 10.
  • the key is reversible and the lock is suitable for receiving the reversible key.
  • the present finding also refers to a high-security unlocking procedure of a closing device, consisting of making the pin 10 come out of the seat 9 of the key 2 pushing it against the security peg 11, so as to take the security peg 11 into open position to allow the rotation of a rotor with respect to a stator of the lock.
  • the pin 10 When the key 2 is inserted the pin 10 is in the withdrawn position and does not interfere with the conventional pegs 17 since, as shown in figure 2, the pin 10 is misaligned with respect to the conventional pegs which have conical ends.
  • the pin 10 When the pin 10 is taken in correspondence with the security peg 11, as shown in figure 3, the pin, which is in the removed position since it is pushed out of the seat 14 by the element 12, makes the security peg 11 slide along the frustum of cone side wall making it slide as indicated by the arrow F, aligning the end of the security peg 11 with the surface of the rotor 7 and the end of the counterpeg 4 associated with it with the surface of the stator 3 and taking the lock into open position.
  • the security peg 11 and the counterpeg 4 associated with it translate in the opposite direction to the one indicated by the arrow F and the aforementioned counterpeg 4 inserts between the rotor and the stator, preventing the mutual rotation.
  • the pin 10 can also be arranged in correspondence with the back of the key; in this case the security peg is housed in the vertical seats.
