Definitions

  • the present invention relates to a cylinder lock.
  • the predefined key for operating the lock When the predefined key for operating the lock is inserted in the slot, it in fact moves the coding pins away from the internal wall of the slot, aligning their end that abuts against the driver pins with the common surface of mutual rotation of the rotor and of the stator.
  • Keys for this type of lock have flared seats, in which the conical tips of the coding pins abut, being pushed therein by the springs by means of the driver pins.
  • the depth of such seats determines the position of the coding pins when the key is inserted in the cylinder and therefore the key adapted to open the lock has seats having a coordinated depth, so as to align the coding pins and the driver pins with the rotor-stator sliding surface, as mentioned.
  • a method for opening this type of lock known as "bumping" which consists in preparing a key that has a cross-section adapted to be inserted in the slot of the lock to be opened and has a profile in which all the seats are flared to the maximum depth.
  • the shoulders which generally define the stop abutment for the insertion of the key in the slot, are filed slightly in order to allow an excess of insertion of the key in the slot.
  • the aim of the present invention is to provide a cylinder lock that cannot be opened with the described method.
  • an object of the invention is to provide a cylinder lock that contrasts the jumping of at least one of its coding pins on its corresponding driver pin.
  • Another object of the invention is to provide a cylinder lock that is simple and easy to use and can be manufactured with relatively low costs.
  • a cylinder lock which comprises:
  • the reference numeral 10 generally designates a cylinder lock, which comprises:
  • a particularity of the lock 10 according to the invention is that it comprises at least one pusher 20, which is accommodated in at least one first hole 21 of the holes 17a and 17b and defines a safety position for at least one first pin 22 of the coding pins 15, in such safety position the first coding pin 22 being spaced from the wall 19 even when the key 14 is inserted in the slot 13.
  • such safety position has the first coding pin 22 that faces the slot 13 and protrudes into it with one end.
  • Figures 1 and 2 show the first coding pin 22 in such safety position.
  • the first coding pin 22 advantageously protrudes into the slot 13 substantially by seven tenths of a millimeter.
  • the pusher 20 conveniently comprises a spring for pushing the first coding pin 22 into the safety position, the elastic means 18 having a lower elastic constant than such pusher spring.
  • the first coding pin 22 is not moved from its safety position, since it does not engage a corresponding seat 23 of the bump key 14a.
  • the seat 23 in fact has been provided at the maximum depth and therefore is unable to engage the first coding pin 22.
  • such key may cause the jumping of the coding pins 15 that abut against it, but not of the first coding pin 22, which by remaining in the safety position prevents the rotation of the rotor 12 within the stator 11 to open the lock.
  • Such pusher spring has a very high elastic constant, so that if one bump key 14a capable of engaging the first pin 22 in its safety position is inserted in the lock, the jumping of the first coding pin 22 on its corresponding driver pin 24 can be imparted by striking the bump key 14a so forcefully as to break the lock.
  • the invention achieves the proposed aim and objects, by providing a cylinder lock that cannot be opened by means of the method known as bumping, since ordinary bump keys do not engage all the opening coding pins and, if a bump key adapted for this purpose is used, the rigidity of the pusher spring is such as to induce the operator to impart such a blow impact to the bump key as to risk the breakage of the pins of the lock.
  • the materials used may be any according to requirements and to the state of the art.
