Definitions

  • the present invention refers to a flat key for a cylindrical lock.
  • flat keys for cylindrical locks currently available on the market, include means of engagement with one or more of the interference organs provided in the stator and the rotor of the lock in order to prevent the rotation of the latter.
  • the interference organs are defined by a certain number of pins, some of which operate as small pistons as they are made up of a pin, a counterpin and suitable springs.
  • the means of engagement are defined by indentations, interacting with one or more small piston, which are for example formedunder the plane defined by the lateral side of the key and which, consequently, develops below the same towards the key axle.
  • an object of the present invention is that of creating a key which provides a high number of cipherings without any modification to the structure of the rotor and which number of cipherings, being the same allows for the creation of a lock at a lower cost.
  • Another object of the present invention is that of creating a flat key for a cylindrical lock which allows for a number of combinations higher than that of the flat keys currently on sale of the same kind.
  • Another object of the present invention is that of creating a flat key which, with the same sizes and mechanical resistance of a traditional key, has a remarkably higher number of cipherings.
  • a flat key for a cylindrical lock type with a rotor which rotates within a stator comprising at least first and second means of commitment lined up between themselves and aligned with at least a first and/or second interference organ, also lined up between themselves, in order to activate them in a suitable manner and to allow for rotation of said rotor in said stator, said first means of engagement being defined by crests that rise from at least one side of said key or which coincide with said face and said second means of engagement being defined by indentations placed below said face and extracted from the body of said key, characterised in that it includes at least third engagement means aimed at activating only at least one third interference organ, lined up with said first and second interference means, and cooperating with the latter to allow for the rotation of the said rotor in said stator.
  • the flat key is adapted for being used in cylindrical type of locks with a rotating rotor 2 in a stator 3.
  • the flat key 6 has first and second means of engagement 5 and 7 which are lined up between themselves and lined up with at least a first and/or second interference organ 4 and 15, also lined up between themselves, in order to activate them so as to allow for rotation of the rotor 2 in the stator 3.
  • the first means of engagement is defined by crests 30 which protrude from the plane 8 defined by at least one side face of the key 6 or which coincide with the plane 8 of one of the two side faces of the key 6.
  • the second means of engagement 7 are, however, placed under the above-mentioned plane 8 and are defined by indentations 7, which extend towards the central axle of the key 6 included between the two side faces defined by the two planes 8, extracted from the structure of the key 6.
  • the key 6 has, furthermore, third means of engagement, indicated as a whole with 9, adapted for activating only at least one third interference organ, generally indicated by 13, which is lined up with the first and second interference means 4 and 15 and cooperates with the latter to allow for the rotation of the rotor 2 within the stator 3.
  • the third means of engagement 9 comprises at least one elevation 9 located on the face of the key sideways in alignment with the first, the second and the third interference organs.
  • the elevation 9 has a first surface 10 which is substantially parallel to the face 8 of the key and at least a second inclined junction surface 11 of the first surface 10 with the face 8 of the key.
  • the first surface 10, as indicated, only activates the third interference organ 13 to allow for rotation of the rotor 2 in the stator 3 of the lock.
  • the elevation 9 may extend partially or along the entire length of the key.
  • the elevation 9 includes at least one insert 12 with a configuration object substantially tapered, and in particular preferably of a conical configuration, adapted for engaging with the third interference organ 13 again to allow for rotation of the rotor 2 in the stator 3.
  • the third interference organ 13 comprises a hollow glass 19 sutably with a truncated base 23, of a substantially truncated-conical configuration.
  • a mobile element 20 aimed at moving in contrast with and activated by elastic means and in particular by a spring 25.
  • the mobile element 20 has a lowered ring area 21 which allows for the wedging impaction of the mobile element with the edge of the glass 19, as illustrated for example in drawing 8.
  • the mobile element 20 has a shaft 22 of a predefined length which extends from the lower area 21 towards the bottom of the glass 19.
  • the first interference organ 4 unlike the third interference organ 13, comprises a hollow glass 19 with a conical base 24.
  • a mobile element 20 which is identical to the mobile element 20 of the third interference organ 13 which moves internally within the hollow cable in contrast with or activated by elastic means in particular, a spring 25.
  • the mobile element 20 has a lowered ring area 21 aimed at its wedging with the edge of the glass 19 and a shaft of a predefined length 22 which extends from the lowered area 21 towards the bottom of the glass.
  • the first interference organ with regards to the third interference organ 13, is different due to its conical base 24 instead of the truncated-conical base 23 of the third interference organ 13.
  • the second interference organ 15 is however defined by a single structure 16, of a substantially cylindrical configuration, with its two opposing ends 17 of a substantially conical configuration.
  • the first, the second and the third interference organs are placed in dedicated seats 18, all of which are the same, extracted from the rotor 2 in order to be placed in any position whatsoever in the seats 18.
  • the mobile element will remain blocked between the bottom of the glass and the pocket 40 in which its head 26 is located, preventing rotation of the rotor with regards to the stator.
  • the pin 13 tends to slope with regards to its axle (as illustrated in drawing 8) and wedging itself between the stator 3 and the rotor 2 by blocking the rotation of the latter with regards to the first and not allowing for the opening of the lock.
  • annular area 21 of the pin can slide through the glass in contrast with or activated by the elastic means 25, thanks to the presence of the head 26 which the mobile element 20 is equipped with, therefore allowing for the rotation of the rotor 2.
  • the shaft 22 is in contact with the conical base 24 of the glass 19 and the annular area 21 is within the glass 19.
  • the invention reaches the objects proposed and achieves important and numerous advantages.
  • the mechanical resistance of the key does not vary as the number of grooves which would weaken the key is not increased, but work is carried out beyond the plane defined, from at least one face of the key.
