Description
- 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.
- Among cylinder locks, much interest is shown in locks that have a seat for accommodating the key which is substantially flat (as is therefore also the associated key), with the pins, which detect the key, operating in a direction that is substantially transverse with respect to the seat (therefore acting on flat portions of the key).
- Such locks are usually identified by the type of key associated with them, and are called "flat key locks".
- The risk of forcing the lock is guarded against with complex encoding of both lock and key: particular break-in techniques make it possible to actuate the pins in order to open the lock, even in the absence of the original key.
- Given the small dimensions of a lock of the type in question it is not substantially possible to increase the number of pins in order to ensure greater security against forcing. As with any lock, furthermore, it is necessary to guard against break-in actions, carried out with lockpicks, the goal of which is to lower the pins in sequence thus making it possible to free the rotor with respect to the stator and, therefore, to open the lock.

WO 2015/008303 discloses a break-in resistant cylinder comprising a stator provided with a substantially cylindrical receptacle for a rotor, the rotor and the stator being affected by at least one channel for at least one respective pin, which can move slidingly within it. The arrangement for retention of the pin partly in the rotor and partly in the stator causes the locking of the rotor, while the open arrangement with alignment of an end edge of the pin with the interface surface between the stator and the rotor, obtained by means of the insertion of an adapted key having a contoured profile in an opening of the rotor that faces the channel, causes the free rotation of the rotor with respect to the stator. 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, and 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 front of the first protruding tab, upon the insertion of the key in the opening of the rotor, is accommodated within a respective profiled slot with consequent substantial complete insertion of the second protruding tab within the cavity of the ogive according to the open arrangement. - 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.
- Within this aim, 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.
- In accordance with the invention, there is provided a break-in resistant lock cylinder for a cylinder lock as defined in the appended claims 1-8, and such a lock and key as defined in the appended claims 9-10.
- According to the invention,
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 abutment shoulder, said at least one channel of said rotor comprising a first section with a substantially larger diameter than the diameter of said central rim and a second section with a substantially smaller diameter than the diameter of said central rim and larger than the diameter of a first protruding appendage, the front of said first protruding appendage, upon the insertion of said key into said opening of said rotor, being accommodated in a respective profiled groove, which has different depths at different longitudinal sections of said key, with consequent substantially complete insertion of the second protruding appendage into the cavity of said ogive according to said open arrangement, said central rim acting as an abutment shoulder comprising a substantially spherical lower portion with a maximum diameter which is not less than the maximum diameter of said rim, said at least one channel of said rotor comprising a first section with a diameter which is substantially larger than the diameter of said central rim and of its spherical lower portion and a second section with a diameter which is substantially smaller than the diameter of said central rim and of its spherical lower portion and larger than the diameter of a first protruding appendage, and interposed between said ogive and an upper planar surface of said central rim of said peg there being arranged elastic means for mutually spacing apart, with consequent arrangement of said at least one pin in said locked arrangement, in the absence of said key inside said opening. - Contrary to in the state of the art, 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.

Figure 9 is a view from above of a further key forming part of embodiments of the invention; -
Figure 10 is a side view of the key inFigure 9 . - With particular reference to the figures, the
reference numeral 1 generally designates a break-in resistant lock cylinder for a cylinder lock, and thereference numeral 2 generally designates an associated key. - The break-in
resistant lock cylinder 1 comprises astator 3 which is provided with a substantiallycylindrical seat 4 for arespective rotor 5. - The
rotor 5 and thestator 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 thechannel 6. - The pin 7 is arranged in a locked configuration when it is partially accommodated in the
rotor 5 and partially accommodated in thestator 3, thus resulting in the immobilization of therotor 5. - 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 thestator 3 and therotor 5, which is obtained by way of the insertion of the adaptedkey 2 with a contoured profile into an opening 9 of therotor 5 facing onto the at least onechannel 6, thus producing the free rotation of therotor 5 with respect to thestator 3. - The at least one pin 7 comprises an
ogive 10 which is provided with acontoured cavity 11 and apeg 12 which is provided with two mutuallyopposite protruding appendages central rim 15 acting as an abutment shoulder. - The at least one
channel 6 of therotor 5 comprises a first section with a substantially larger diameter than the diameter of thecentral rim 15 and a second section with a substantially smaller diameter than the diameter of suchcentral rim 15 and larger than the diameter of afirst protruding appendage 13. - The front of the
first protruding appendage 13, upon the insertion of therespective key 2 in theopening 9 of therotor 5, is accommodated in a respective profiledgroove 18 of thiskey 2. - The profiled
groove 18 has different depths at different longitudinal sections of thekey 2. - It should be noted that the variation of the depth of the
groove 18 is provided continuously, with a joined and continuous surface so that thefirst protruding appendage 13 of the pin 7 can slide easily thereon (during the insertion of thekey 2 in the opening 9) without the possibility of phenomena of sticking arising. - The possibility is not excluded of adopting
grooves 18 in which the depth varies according to mutually connected consecutive flat portions: this second possibility may be simpler in terms of practical implementation. - When the
key 2 is completely inserted in theopening 9, the substantially complete insertion occurs of thesecond protruding appendage 14 in thecavity 11 of theogive 10 according to the configuration of the pin 7, which permits the opening of thelock cylinder 1. - In this first case the
groove 18 will be linear and will have a direction of extension substantially parallel to the longitudinal axis of thekey 2. - According the invention, the
central rim 15 acting as an abutment shoulder comprises a substantially spherical lower portion which has amaximum diameter 16 which is not less than the maximum diameter of therim 15. - It should be noted that 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 therim 15, to the extent that it is not possible to distinguish therim 15 from the upper face of the hemispherical portion. - In such case the at least one
channel 6 of therotor 5 will comprise a first section with a substantially larger diameter than the diameter of thecentral rim 15 and of its spherical lower portion (themaximum 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 afirst protruding appendage 13. - It should be noted that, in any case, according to the invention,
elastic means 19 are interposed between theogive 10 and thepeg 12 for mutually spacing apart. - 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 thecylinder 1, in the absence of akey 2 inside theopening 9. - The
contoured cavity 11 is shaped so as to define a seat of greater extent, which is defined starting from its edge facing toward and proximate to thepeg 12 up until a point proximate to its midpoint, and a pit with a diameter slightly larger than that of thesecond appendage 14 of thepeg 12, arranged downstream of the seat of greater extent. - This shape structure will make it possible to trap the
second appendage 14 of thepeg 12 upon attempts at opening executed without using the key 2 (therefore upon break-in attempts). - It should be noted that 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. In this manner it is possible to provide specific forms of encoding in which thepeg 12 has a different orientation with respect to the ogive 10 (i.e. that the axis of thepeg 12 and the axis of theogive 10 are mutually inclined at the correct open arrangement, or that thepeg 12 can be trapped in the contouring of theogive 10 when inclined in directions other than the direction that would be imposed by thegroove 18 of the key 2). - According to a particularly advantageous embodiment from an implementation point of view, the
portion 3a, of thestator 3, of the at least onechannel 6 can preferably be constituted by a recess, which is delimited by inclined planes which join with the inner walls of thecylindrical accommodation 4. - In such case, 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 therotor 5 with respect to thestator 3. - According to an embodiment of undoubted practical and applicative interest which offers high levels of security against forcing, the pins 7 can be a plurality, and are substantially aligned along the opening 9 of the
rotor 5. - In such case the
pegs 12 of the pins 7 will be differently shaped for the insertion of the respectivefirst appendages 13 in theprofiled groove 18 of thekey 2 and for the accommodation of a respectivesecond appendage 14 in a respective pit of arespective ogive 10. - Having a plurality of pins 7 makes it possible to execute a more complex encoding of the
key 2, by taking advantage of the variations in depth and direction of thegroove 18. - The fact that the
groove 18 varies its depth continuously, without defining steps, allows thefirst appendages 13 to easily slide along them without risk of jamming, and it enables a potentially infinite number of forms of encoding. - In fact 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 eachappendage 13 will rest: this means thatpegs 12 can be designed for a specific and well-defined depth of the groove 18 (at the cross-section thereof on which thecorresponding appendage 13 lies) and/or for a specific and well-defined inclination thereof (with which the front of therespective appendage 13 will have to suitably mate). - It should be noted that, with regard to an embodiment which is intended to further increase the level of security offered against forcing, the
rotor 5 and thestator 3 comprise at least one further through hole, which is substantially opposite thechannel 6 and is aligned with a second profiled groove of thekey 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 thestator 3, and an open configuration, in which it has an end thereof inserted in the second groove and is completely contained in therotor 5. - The presence of two elements for reading the
grooves 18 present on the key (the pin 7 and the moveable tumbler) makes it possible to substantially increase the level of security against forcing. - It should be noted that embodiments of the present invention also relates to a
key 2 in combination with break-inresistant lock cylinders 1 whereby thekey 2 comprises, on at least oneflat surface 20 thereof, at least one profiledgroove 18, which has different depths at different longitudinal sections of thekey 2. - The
groove 18 is arranged between theend tip 21 of thekey 2 and theregion 22 thereof which is intended, when thekey 2 is in the configuration of insertion in therespective lock cylinder 1, to be aligned with the front surface of thelock 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. - It is essential to note that, according to a particularly advantageous embodiment in terms of increasing the number of possible forms of coding that can be provided, the at least one profiled
groove 18, which has different depths at different longitudinal sections of thekey 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.
- It should be noted that, if it is desired to provide a key 2 that has extremely high levels of security and therefore is adapted to cooperate with a particularly
secure lock cylinder 1, thegrooves 18 can be at least two in number, arranged onflat surfaces 20 which are symmetrically mutually opposite with respect to the central longitudinal axis of thekey 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 arespective key 2. - The
lock cylinder 1 will be of the type comprising astator 3 which is provided with a substantiallycylindrical accommodation 4 for arotor 5. - The
rotor 5 and thestator 3 will be affected by at least onechannel 6 for at least one respective pin 7, which is slideably moveable inside it. - The arrangement, for locking, of partial accommodation of the at least one pin 7 in the
rotor 5 and in thestator 3 results in the immobilization of therotor 5, with consequent stable closing of the lock (and therefore of the lock cylinder 1). - 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 thestator 3 and therotor 5, which is obtained by way of the insertion of the adaptedkey 2, with a contoured profile, into anopening 9 of therotor 5 facing onto the at least onechannel 6, produces the free rotation of therotor 5 with respect to thestator 3. - According to the invention, the at least one pin 7 comprises an
ogive 10 which is provided with acontoured cavity 11 and apeg 12 which is provided with two mutually opposite protrudingappendages central rim 15 acting as an abutment shoulder. - Such at least one
channel 6 of therotor 5 comprises, in turn, a first section with a substantially larger diameter than the diameter of thecentral rim 15 and a second section with a substantially smaller diameter than the diameter of thiscentral rim 15 and larger than the diameter of the first protrudingappendage 13. - The
respective key 2, in turn, comprises, on at least oneflat surface 20 thereof, at least one profiledgroove 18, which has different depths at different longitudinal sections of thekey 2. - The
groove 18 is arranged between theend tip 21 of thekey 2 and theregion 22 thereof which is intended to be aligned with the front surface of therespective lock cylinder 1. - When the
key 2 is inserted in thechannel 6, the front of the first protrudingappendage 13 is inserted in thegroove 18. - This will produce the consequent substantially complete insertion of the second protruding
appendage 14 in thecavity 11 of theogive 10 according to the open arrangement. - In such lock according to the invention, the
central rim 15 acting as an abutment shoulder comprises a substantially spherical lower portion with amaximum diameter 16 which is not less than the maximum diameter of therim 15. - The at least one
channel 6 of therotor 5 in such case will comprise a first section with a substantially larger diameter than the diameter of thecentral 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 thecentral rim 15 and of its spherical lower portion, and larger than the diameter of a first protrudingappendage 13. - In such case the at least one profiled
groove 18 will have different depths at different longitudinal sections of thekey 2 and will also have a substantially variable direction. - Advantageously 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 anogive 10 and a peg 11 (which is intended to be partially accommodated in acontoured cavity 11 of such ogive 10): thesecond appendage 14 of thepeg 12 and thecavity 11 of theogive 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 thegroove 18 of the key 2). - If the
groove 18 also comprises variations of its direction, thesecond appendage 14 of thepeg 12 and thecavity 11 of theogive 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 thegroove 18 of the key 2). - The fact that the depth of the
groove 18 can vary continuously offers the possibility of providing different forms of encoding according to a potentially infinite number of combinations, by dint of the infinite heights at which thepeg 12 can be arranged in the correct open configuration. - If the variation of the depth of the
groove 18, with the continuous possibilities this offers, is then combined with the fact that its direction can also vary, with the continuous possibilities this offers (thus creating tortuous and twisting patterns), it can be seen that thelock cylinder 1 according to the invention and the key 2 in combination with such a lock result in a considerable technical progress in the sector of locks, by offering extremely high levels of security, without requiring the presence on thekey 2 of moveable elements, which constitute a criticality during the manufacturing step (in that they are complex and costly) and they are also delicate (they can be damaged with impacts and/or drops). - Effectively the break-in
resistant lock cylinder 1 for a cylinder lock simultaneously offers a simple structure and a high level of security. - Positively the
key 2 is adapted to increase the level of security of thelock cylinders 1 with which it is mated. - The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- For example the
ogive 10 can be constituted by an elongated shell (of the type of an at least partially concave bar or rod) which is provided with a plurality of internal seats which define, taken together, a specificcontoured cavity 11. - Each seat would be designed to accommodate a corresponding second protruding
appendage 14 of arespective peg 12. - In such case, only the condition in which all the
pegs 12 are accommodated in the respective seats (they therefore being contained overall in thecavity 11 that the seats constitute) can result in the opening of thelock cylinder 1. - In practice, the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
- Where the technical features mentioned in any claim are followed by reference numerals and/or signs, those reference numerals and/or signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference numerals and/or signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference numerals and/or signs.
