Definitions

  • the present invention relates to a break-in resistant lock cylinder for a cylinder lock and to an associated key.
  • the lock cylinder constitutes the principal active component of a, lock: it is constituted by a stator which is integral with the lock and inside which a rotor is selectively rotatable.
  • the rotor is provided with an opening for the insertion of a coded key: interposed between the rotor and the stator are adapted pins of predefined length, which are kept elastically in a position of interference between the rotor and the stator.
  • the coding pattern of the key enables the alignment of the end edge of each pin with the surface for interfacing between the stator and the rotor, with consequent freedom of the rotor to rotate with respect to the stator.
  • the coding pattern of the key consists of the provision of a contoured profile thereof which is provided with a pattern such that, once the key is completely inserted in the opening of the respective rotor, each pin, pushed by a respective portion of the contoured profile of the key in contrast with the elastic means, has its edge aligned with the interface surface between rotor and stator.
  • Such locks are usually identified by the type of key associated with them, and are called “flat key locks”.
  • the pin comprises an ogive provided with a contoured cavity and a coding part provided with two mutually opposite protruding tabs and with a substantially spherical central portion
  • the channel of the rotor comprises a first part that has a substantially larger diameter than the spherical central portion and a second part whose diameter is substantially smaller than the diameter of the spherical portion and larger than the diameter of a first protruding tab.
  • the principal aim of the present invention is to solve certain drawbacks, by providing an alternative break-in resistant lock cylinder for a cylinder lock which is particularly secure against break-in attacks and lock-picking.
  • an object of the invention is to provide a break-in resistant lock cylinder with a simple structure and a high level of security.
  • Another object of the invention is to provide a break-in resistant lock cylinder and a key for break-in resistant lock cylinders which have a structure and a geometry which are alternative and different with respect to conventional ones.
  • Another object of the present invention is to provide a break-in resistant lock cylinder and an associated key that are low cost, easily and practically implemented, and safe in use.
  • claim 1 provides a break-in resistant lock cylinder for a cylinder lock, of the type comprising a stator which is provided with a substantially cylindrical accommodation for a rotor, said rotor and said stator being affected by at least one channel for at least one respective pin, which is slideably moveable inside it, the arrangement, for locking, of said at least one pin partly in said rotor and partly in said stator resulting in the immobilization of said rotor, the arrangement, for opening, with the alignment of an end edge of said at least one pin with the interface surface between stator and rotor, which is obtained by way of the insertion of an adapted key with a contoured profile into an opening of the rotor facing onto the at least one channel, resulting in the free rotation of said rotor with respect to said stator, said at least one pin comprising an ogive which is provided with a contoured cavity and a peg which is provided with two mutually opposite protruding appendages and with a central rim acting as an
  • the peg according to the invention essentially provides a central rim acting as abutment shoulder and having an upper planar surface, such that the elastic means can be interposed between the ogive and this planar surface.
  • the break-in resistant lock cylinder 1 comprises a stator 3 which is provided with a substantially cylindrical seat 4 for a respective rotor 5.
  • the rotor 5 and the stator 3 are affected by at least one channel 6 (which is parallel to the longitudinal axis of the rotor 5) for at least one respective pin 7, which is slideably moveable inside the channel 6.
  • the pin 7 is arranged in an open configuration when the alignment occurs of an end edge 8 of the at least one pin 7 with the interface surface between the stator 3 and the rotor 5, which is obtained by way of the insertion of the adapted key 2 with a contoured profile into an opening 9 of the rotor 5 facing onto the at least one channel 6, thus producing the free rotation of the rotor 5 with respect to the stator 3.
  • the at least one pin 7 comprises an ogive 10 which is provided with a contoured cavity 11 and a peg 12 which is provided with two mutually opposite protruding appendages 13 and 14, and with a central rim 15 acting as an abutment shoulder.
  • the profiled groove 18 has different depths at different longitudinal sections of the key 2.
  • the variation of the depth of the groove 18 is provided continuously, with a joined and continuous surface so that the first protruding appendage 13 of the pin 7 can slide easily thereon (during the insertion of the key 2 in the opening 9) without the possibility of phenomena of sticking arising.
  • the groove 18 will be linear and will have a direction of extension substantially parallel to the longitudinal axis of the key 2.
  • the central rim 15 acting as an abutment shoulder comprises a substantially spherical lower portion which has a maximum diameter 16 which is not less than the maximum diameter of the rim 15.
  • the hemispherical lower portion can have a maximum diameter 16 which at most coincides with the diameter of the rim 15: in such case such spherical lower portion can have its top coinciding and perfectly joined with the rim 15, to the extent that it is not possible to distinguish the rim 15 from the upper face of the hemispherical portion.
  • the at least one channel 6 of the rotor 5 will comprise a first section with a substantially larger diameter than the diameter of the central rim 15 and of its spherical lower portion (the maximum diameter 16 of which was defined previously) and a second section which will have a diameter comprised substantially between the diameter of the central rim 15 (including its spherical lower portion) and the diameter of a first protruding appendage 13.
  • the presence of the elastic means 19 will therefore have the goal of keeping under elastic force the at least one pin 7 in the preset locked configuration of the cylinder 1, in the absence of a key 2 inside the opening 9.
  • This shape structure will make it possible to trap the second appendage 14 of the peg 12 upon attempts at opening executed without using the key 2 (therefore upon break-in attempts).
  • the seat of greater extent and the pit of the contoured cavity 11 are arranged in a mutual position which is chosen from among concentricity, parallelism without alignment, and completely skewed.
  • the peg 12 has a different orientation with respect to the ogive 10 (i.e. that the axis of the peg 12 and the axis of the ogive 10 are mutually inclined at the correct open arrangement, or that the peg 12 can be trapped in the contouring of the ogive 10 when inclined in directions other than the direction that would be imposed by the groove 18 of the key 2).
  • the portion 3a, of the stator 3, of the at least one channel 6 can preferably be constituted by a recess, which is delimited by inclined planes which join with the inner walls of the cylindrical accommodation 4.
  • the ogive 10 will comprise a tapered end tip with an axial symmetry (for example frustum-shaped, ellipsoidal, spherical etc.) which is adapted to slide on the inclined planes, during the rotation of the rotor 5 with respect to the stator 3.
  • an axial symmetry for example frustum-shaped, ellipsoidal, spherical etc.
  • the pins 7 can be a plurality, and are substantially aligned along the opening 9 of the rotor 5.
  • groove 18 varies its depth continuously, without defining steps, allows the first appendages 13 to easily slide along them without risk of jamming, and it enables a potentially infinite number of forms of encoding.
  • any depth value of the groove 18 can be provided, just as it is possible to take advantage of the inclination of the bottom surface of the groove on which the front of each appendage 13 will rest: this means that pegs 12 can be designed for a specific and well-defined depth of the groove 18 (at the cross-section thereof on which the corresponding appendage 13 lies) and/or for a specific and well-defined inclination thereof (with which the front of the respective appendage 13 will have to suitably mate).
  • the rotor 5 and the stator 3 comprise at least one further through hole, which is substantially opposite the channel 6 and is aligned with a second profiled groove of the key 2, for the slideable accommodation of at least one respective tumbler which is moveable.
  • Such tumbler is movable between a locked configuration, in which it is interposed between the rotor 5 and the stator 3, and an open configuration, in which it has an end thereof inserted in the second groove and is completely contained in the rotor 5.
  • embodiments of the present invention also relates to a key 2 in combination with break-in resistant lock cylinders 1 whereby the key 2 comprises, on at least one flat surface 20 thereof, at least one profiled groove 18, which has different depths at different longitudinal sections of the key 2.
  • the groove 18 is arranged between the end tip 21 of the key 2 and the region 22 thereof which is intended, when the key 2 is in the configuration of insertion in the respective lock cylinder 1, to be aligned with the front surface of the lock cylinder 1.
  • the groove 18 will have a linear progression and can be parallel to the longitudinal axis of the key or inclined with respect thereto.
  • the at least one profiled groove 18, which has different depths at different longitudinal sections of the key 2 has a substantially variable direction.
  • the variation of the direction can occur as a sequence of consecutive mutually inclined straight portions which are mutually connected, or as a curved line with only one concavity or with one or more consecutive bends.
  • the grooves 18 can be at least two in number, arranged on flat surfaces 20 which are symmetrically mutually opposite with respect to the central longitudinal axis of the key 2.
  • the present invention defines the protection for a break-in resistant lock which is constituted by a break-in resistant lock cylinder 1 and in certain embodiments thereof by such a break-in resistant lock cylinder in combination with a respective key 2.
  • the lock cylinder 1 will be of the type comprising a stator 3 which is provided with a substantially cylindrical accommodation 4 for a rotor 5.
  • the rotor 5 and the stator 3 will be affected by at least one channel 6 for at least one respective pin 7, which is slideably moveable inside it.
  • the arrangement for opening which corresponds to the alignment of an end edge 8 of the at least one pin 7 with the interface surface between the stator 3 and the rotor 5, which is obtained by way of the insertion of the adapted key 2, with a contoured profile, into an opening 9 of the rotor 5 facing onto the at least one channel 6, produces the free rotation of the rotor 5 with respect to the stator 3.
  • the at least one pin 7 comprises an ogive 10 which is provided with a contoured cavity 11 and a peg 12 which is provided with two mutually opposite protruding appendages 13, 14 and with a central rim 15 acting as an abutment shoulder.
  • Such at least one channel 6 of the rotor 5 comprises, in turn, a first section with a substantially larger diameter than the diameter of the central rim 15 and a second section with a substantially smaller diameter than the diameter of this central rim 15 and larger than the diameter of the first protruding appendage 13.
  • the respective key 2 in turn, comprises, on at least one flat surface 20 thereof, at least one profiled groove 18, which has different depths at different longitudinal sections of the key 2.
  • the groove 18 is arranged between the end tip 21 of the key 2 and the region 22 thereof which is intended to be aligned with the front surface of the respective lock cylinder 1.
  • the central rim 15 acting as an abutment shoulder comprises a substantially spherical lower portion with a maximum diameter 16 which is not less than the maximum diameter of the rim 15.
  • the at least one channel 6 of the rotor 5 in such case will comprise a first section with a substantially larger diameter than the diameter of the central rim 15 and of its spherical lower portion.
  • the channel 6 will further comprise a second section with a substantially smaller diameter than the diameter of the central rim 15 and of its spherical lower portion, and larger than the diameter of a first protruding appendage 13.
  • the at least one profiled groove 18 will have different depths at different longitudinal sections of the key 2 and will also have a substantially variable direction.
  • the present invention solves the above mentioned problems, by providing a break-in resistant lock cylinder 1 for a cylinder lock which is particularly secure against break-in attacks and lock-picking, by dint of the adoption of pins 7 which are constituted by an ogive 10 and a peg 11 (which is intended to be partially accommodated in a contoured cavity 11 of such ogive 10): the second appendage 14 of the peg 12 and the cavity 11 of the ogive 10 are shaped complementarily so as to be able to mate only following a specific geometric alignment as a consequence of a specific height of the peg 12 (such height is controlled by the particular depth of the groove 18 of the key 2).
  • the groove 18 also comprises variations of its direction, the second appendage 14 of the peg 12 and the cavity 11 of the ogive 10 will be able to mate only following a specific geometric alignment as a consequence of a specific height and of a specific angular arrangement of the peg 12 (such angular arrangement is controlled by the particular shape structure of the groove 18 of the key 2).
  • Each seat would be designed to accommodate a corresponding second protruding appendage 14 of a respective peg 12.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
