Definitions

  • the present invention relates to a lock with a related key suitable for installation in doors, main entrance doors, and in all applications requiring closure by means of a key.
  • the aim of the present invention is to provide a lock with related key in which the pins have particular break-in resistant shapes and in which the shape of the pins is perfectly compatible with the access of the key.
  • an object of the present invention is to provide a lock with a related key which has traditional dimensions and is provided with portions suitable to increase the difficulty of any break-in attempt.
  • the present lock with related key of the type comprising a stator provided with a substantially cylindrical longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a coded key, said rotor and said stator comprising a plurality of channels which are substantially aligned and face each other when the cylinder is in the closed configuration, channels for accommodating respective pins, complementary pins and any elastic means meant to prevent the rotation of the rotor within the stator in the absence of the key within said longitudinal recess, at least one of said pins having at least one substantially lateral protruding tab which has an upper edge which is suitably contoured and said key having a cross-section which is shaped complementarily to the cross-section of the longitudinal recess when said pins, at the regions that are aligned with said tab,

  • Figure 11 is a partially sectional side view of a lock according to the invention in which the corresponding key is inserted. Ways of carrying out the invention
  • the reference numeral 1 generally designates a lock with a corresponding key.
  • the lock 1 comprises a stator 2 which is provided with a substantially cylindrical longitudinal cavity 3 for accommodating a rotor 4 with a longitudinal recess 5 for the insertion of a coded key 6.
  • the rotor 4 and the stator 2 comprise a plurality of channels 7 which are substantially aligned and face each other when the cylinder 1 is in the closed configuration.
  • the containment channels 7 are designed to accommodate respective pins, complementary pins 9 and optional elastic means 7a: the purpose of the pins 8 and of the complementary pins 9 is to prevent the rotation of the rotor 4 within the stator 2 in the absence of the key 6 within the longitudinal recess 5.
  • At least one of the pins 8 has at least one substantially lateral tab 10 which protrudes and has an appropriately contoured upper edge 11.
  • the key 6 has a cross-section which is complementary with respect to the cross-section of the longitudinal recess 5, particularly when the pins 8 are in the configuration for uncoupling the stator 2 and the rotor 4: i.e., when the shear line between the pin 8 and the complementary pin 9 is aligned with the shear line between the stator 2 and the rotor 4.
  • the key 6 therefore accommodates by contact the end of pins 8 in respective coding recesses 12 and the contoured edge 11 of the corresponding tab 10 on appropriately provided complementary shaped portions 13.
  • At least one of the lateral tabs 10 which protrude from the pin 8 can move with respect to said pin 8 and has at least one portion 15 which is stably related with the pin 8.
  • a movable lateral tab 14, which protrudes from the pin 8 can perform a translational motion with respect to said pin 8, having at least one portion 15 which is guided within a respective passage 16 of said pin 8.
  • the pin 8, seen in cross-section must be C-shaped, with an axial longitudinal cavity which constitutes the passage 16 to accommodate the portion 15 which is shaped complementarily with respect to it; in the figure, the portion 15 and the passage 16 both have a substantially cylindrical shape.
  • the elastic means 7a comprise respective elastic means 16a which have an axial action and are substantially related with the portion 15 of the tab 14 to elastically force it toward the top of the pin 8, while the remaining part of the means 7a is related with the pin 8.
  • the complementary pin 9 also is substantially tubular (with dimensions which are similar to those of the pin 8) and accommodates a rod 21 : axially acting elastic means are interposed above the head 22 of the rod 21 and are designed to move the entire pin 8 and the parts that are rigidly coupled thereto, while the means 16a are accommodated below the head 22, to the bottom of the channel 7, and their elastic contribution is also transferred to the tab 14.
  • the movable lateral tab 14, which protrudes from the pin 8, can rotate with respect to said pin 8, having at least one portion 15 which is pivoted about a fixed axis 17 which is rigidly coupled to the pin 8.
  • said tab 14 can comprise a respective elastic element (not shown in the figure) for forcing the rotation of said tab 14 with respect to the axis 17.
  • the channels 7 of the rotor 4 have a lateral slot 18 for slidingly accommodating the tab 10 of the pins 8.
  • One of the tabs 10, and particularly the tab 14, can have on its upper surface a multiple of laterally adjacent abutments 19 which constitutes the contoured portion 11; the abutments 19 are complementary with respect to respective thickness variations which constitute abutment portions 16, which constitute the complementarily shaped portions 13 of the cross- section of the key 6, and are related therewith when the key 6 is inserted in the longitudinal recess 5.
  • the part of the key 6 that is provided with the complementarily shaped abutment portions 13 is substantially the part along the longitudinal axis: this occurs because the pins 8 act against the substantially central surface of the flat face toward which they are pushed by the elastic action of the means 7a.
  • the pins 8 can be provided with a fixed lateral tab 10 or movable lateral tab 14, and the key 6 can thus have a succession of parts which are provided with complementarily shaped portions 13 distributed in a substantially longitudinal direction.
  • the fixed tabs 10 and/or movable tabs 14 can also be two (one for each type or both fixed 10 or both movable 14), provided, on the respective upper rim, with specific contoured abutment edges 11.
  • the key 6 must have a profile which comprises, on each of the mutually opposite coded faces, two complementarily shaped portions 13 which are shaped complementarily with respect to the respective contoured edges 11 for the abutment of the pairs of fixed tabs 10 and/or movable tabs 14 which are rigidly coupled to the pin 8.
  • the fixed tabs 10 and/or movable tabs 14 can be a plurality, even only partly provided with the respective contoured edge 11.
  • the key 6 must have a profile which comprises, on each of the mutually opposite coded faces, a plurality of complementarily shaped portions 13 which are shaped complementarily with respect to the respective contoured abutment edges 11.
  • the part of the key 6 provided with the complementarily shaped abutment portions 11, i.e., the one arranged substantially along the longitudinal axis of said key 6, can comprise at least one movable element.
  • Said mobility can also be only partial, for example if the movable element is constituted by a small plate which is pivoted within a through opening provided in said key 6.

Au moins une des broches (8) présente au moins une languette en saillie sensiblement latérale (10) qui présente un bord supérieur (11) qui a un profil adapté et la clé (6) présente une section transversale qui est conformée de manière complémentaire à la section transversale de la cavité longitudinale (5) lorsque les broches (8), au niveau des zones qui sont alignées avec la languette (10), sont dans la configuration pour désengager le stator (2) et le rotor (4), s'adaptant en contact avec l'extrémité des broches (8) dans des évidements de codage respectifs (12) et le bord profilé (11) de la languette correspondante (10) sur des parties conformées de manière complémentaires prévues à cet effet (13). Au moins une (14) des languettes latérales (10) qui sont en saillie depuis la broche (8) peut se déplacer par rapport à la broche (8) et présente au moins une partie (15) qui est associée de manière stable à la broche (8).
