Definitions

  • the invention relates to locksmithing.
  • a lock device type comprising a fixed barrel, or barrel, integrally accommodating a socket which in turn houses one internal block comprising a stack of shaped washers coding, securely enclosed between two end discs, suitable for admitting panons from a wrench to a stop, to control the rotation of these panons and whether or not to allow them to pass through a slot outlet, formed in the end wall of the socket, for training purposes of at least one bolt.
  • Such a device has drawbacks of structure that can affect its resistance to possible breaking in.
  • a first drawback lies in the realization of the internal block. Indeed, although being jointly and securely enclosed between two end discs, the stack of washers coding does not form a compact body. Also, during an attempted break-in and in the case of training forced rotation of the internal block, each washer coding can, due to its small thickness, twist individually until you can access to the rear end disc passage slot.
  • the invention aims to provide a solution to these problems and to obtain a high security lock device.
  • An object of the invention is to overcome the drawbacks aforementioned by making major modifications, but simple to make, to the constituent elements of this lock device.
  • An object of the invention is to strengthen the cohesion of the internal block housed inside the current guns.
  • the invention also aims to modify the panetons keys used for this lock device for, on the one hand, take into account this arrangement tending to increase the consistency of the internal block, and for, else hand, making the reproduction of keys more difficult.
  • Another object of the invention is to make the depression more difficult ratchets.
  • Another object of the invention is to make it more difficult decoupling in rotation of the internal block relative to to the socket and the socket relative to the barrel.
  • Another object of the invention is to increase the difficulty taking a key impression on the barrel.
  • the invention therefore relates to a lock device of the type described above, in which the internal block further includes an intermediate disc, located between the two end discs and having a passage suitable for allowing access to the keys of the key up to said stop and their rotation, said disc intermediate presenting by its thickness and its surface high strength, compared to thin washers of the set of washers, to any attempted break-in tending to bend the shaped profile of coding of the washers.
  • the device comprises connecting means forming at least part of attachment means for securing the intermediate disc with said end discs and said washers coding.
  • the socket can accommodate, in addition, a terminal disc fixed inside of it in front of its end wall and comprising a passage slot homologous to the exit slot of this end wall.
  • this terminal disc is secured of the internal block in rotation and can be fixed on the internal face of the end wall of the socket.
  • the internal block can be secured in barrel rotation through connecting means connected to the front end disc of the internal block, and to the rear face of the inlet wall (10), or front wall, of the barrel.
  • the end disc rear of the internal block comprises means forming projection, located on the front face of this disc, and susceptible to cooperate with the keys of the key when they have reached said stop, to authorize or not their rotation.
  • the block internal may include a set of at least three shutter arms (ratchet) cooperating mutually by their profile respective for, in a first position, sealing the rear end disc passage slot, and for retract, in a second position, to release this passage slot.
  • the key entry slot, located on the front wall of the barrel is rectangular, substantially adjusted with respect to around a cross section of the footprint of key.
  • the shape rectangular of this entry slit and its dimensioning make it more difficult to take the impression key by a malicious third party.
  • the invention also provides a key specific to cooperate with the lock device in question above.
  • the key has two symmetrically small knobs arranged on either side of the key shank and each comprising a transverse notch capable of cooperate with the passage of the intermediate disc.
  • at least one of the panets has a notch longitudinal likely to cooperate with the means protruding, located on the front of the end disc back.
  • Figure 1 illustrates a front view of a barrel 1 while that figure 2 illustrates a right view which is actually a view from the front as seen by a user placed in front of the barrel to introduce its key.
  • a front face will be a face facing forward of the barrel as opposed to a rear face and a front element will be a closer element from the front of the barrel as a rear element.
  • Barrel 1 is a hollow cylindrical part with a length minimum 45 mm with a front wall 10 fitted with a rectangular key entry slot 102.
  • a front wall 10 fitted with a rectangular key entry slot 102.
  • symmetry of revolution of the barrel makes it possible to represent this entry slit 102 in several positions. We have chosen to illustrate it here vertical position. We will see, later, that the illustrations other figures take into account, unless indicated on the contrary, from this vertical position of the entry slit.
  • a key used for this lock device is illustrated in Figure 3 and bears the reference 4. It comprises a rod 41 extended at one end by a ring key 43 and supporting, in the vicinity of its other end, symmetrically, two panets 40. Each of these plates has a transverse notch 45 of a predetermined depth and whose function will be explained below. Each paneton also has a longitudinal notch 44 of a predetermined depth, and located on the edge of the pad connecting to the rod 41 in the vicinity of the free end thereof, that is to say its front end. The function of these longitudinal notches 44 will be explained below.
  • the rod of this key has a housing 46 containing means 47 suitable for cooperating, possibly remotely, with the means of the device lock, likely to convey information two states.
  • These two states can represent presence or absence of key information in the lock device and condition, for example, electric opening of a bolt by an appropriate mechanism.
  • These means 47 can be for example a electrical stud cooperating with an electrical contact or still a magnet cooperating with a relay arranged on or near the device. We can consider, in in this case, let the cooperation take place at a distance. For some reasons of simplicity, these means allowing to convey two-state information is not shown in the figures because their location in the device lock depends on the type of means used. It is however necessary to provide at least in barrel 1 and in the socket 2, passages 108 and 208 counterparts allowing to house at least some of these resources.
  • a cross section 42 of the imprint of this key is illustrated schematically in Figure 4.
  • the slice of the panetons 40 is represented, around this section 42, the trace of the entrance slit 102.
  • the width of this inlet slot 102 is at least equal to the diameter of the rod 41 of the key 4 and, preferably, very slightly higher. So here, the width of this slit entry is around 5.5 mm for a diameter of key shank in the order of 4 mm.
  • the height of this entry slit is at least equal to the largest distance between two symmetrical points of the teeth panetons 40 and, preferably, slightly higher. For example, this height is of the order of 16 mm for a section height of the order of 15 mm.
  • the rectangular shape of this entry slot 102 and its dimensioning thus make it more difficult to take the key fingerprint by a malicious third party.
  • a cover 5 is provided in front of the front face 100 of the front wall 10 of the barrel. This cover 5 is movable in rotation around a axis 50 inserted, preferably, above the slot input 102 along its longitudinal axis of symmetry, from so as to hide by gravity this entry slot 102.
  • the use of such a cover 5 protects the entrance drum 1, which is necessary in some applications and what was not foreseen in the devices of front lock.
  • Barrel 1 is securely attached to an opening such that a door, through, for example, four screws located in four holes 114 in the wall rear annular 11 of the barrel. We therefore notice that the drum 1 is "closed” at its front wall and opens out at its rear wall.
  • blind 103 On the periphery of the rear, or internal face, 101, of the front wall 10 of the barrel 1, two holes are provided blind 103, preferably diametrically opposite.
  • FIG. 5 illustrates a front view of a socket 2 intended to be housed in the barrel 1 and
  • FIG. 6 illustrates a left view of this socket 2, that is to say a rear view.
  • This socket is also a cylindrical piece hollow, about 30 mm long, with a rear wall, or end wall, 21 provided with an outlet slot 212 crossing this rear wall from its face front, or internal, 210 to its rear face, or external, 211.
  • the sleeve 2 is positioned in the barrel 1, so the exit slot 212 is offset by approximately pi / 2 radians relative to the entrance slot 102. So, this slot 212 is shown horizontal in the figure 6.
  • the socket 2 opens out at its end front and has two through passages 207 formed in the side wall and whose function will be explained below.
  • These coding washers 30 have a varying thickness between 0.3 mm and 0.5 mm, while the thickness of the disc front end is of the order of 1.5 mm, while the thickness of the rear end disc is of the order of 3 mm.
  • the internal block also includes an intermediate disc 34 with a thickness of about 1.5 mm, interposed in the set of coding washers 30, and the function will be explained below.
  • Front and rear end discs, washers as well as the intermediate disk 34 are mutually secured by two screws 33 whose heads 330 are housed in housings, preferably diametrically opposite, formed in the end disc rear 32.
  • the rod of each screw 33 passes through the washers coding and the intermediate disk 34 and then screws into threaded holes in the disc front end 31, head housing counterparts quote.
  • the length of these screws 33 is such that, once the internal block 3 assembled, the end 331 of each screw 33 slightly exceeds this internal block, around about 1.5 mm, to be accommodated in the blind holes 103 provided in the front wall of the barrel 1.
  • the internal block 3 is also secured in rotation relative to socket 2 via two pins 7 inserted in the rear end disc 32 and passing through the passages 207 made in the wall side of the socket. These passages 207 corresponding at the passages 107 of the barrel, the pins 7 also pass through these passages 107 to also secure in rotation of the sleeve relative to the barrel.
  • the length of the socket is such that, once positioned in the barrel, the distance between the front face 100 of the front wall 10 of the barrel and the rear face 211 of the rear wall 21 of the socket 2 is substantially equal to the length of the rod 41 of the key 4 between the ring key 43 and the bit 40. So when the key is completely inserted into the barrel and has passed through the socket, the key ring 43 abuts against the face before 100 of barrel 1, and the panetons are located outside the socket 2 so that it can be moved freely in rotation for training purposes of at least one bolt of the lock (not shown here).
  • the internal block 3 includes a set 6 of three shutter members this slot 322 whose characteristics will be explained below.
  • a disc terminal 22 At the bottom of the socket, is glued on the front face 210 from the rear wall, or terminal 21, from the sleeve, a disc terminal 22 with a thickness of approximately 3 mm.
  • This disc has a passage slot 222 homologous to the outlet slot 212 of the socket 2, that is to say placed horizontally.
  • the rear end disc 32 of the internal block 3 is secured in rotation to the terminal disc 22 by a finger 324 mounted substantially perpendicularly between these two discs. The internal block 3 is thus secured in rotation relative to the socket 2.
  • the front end disc 31 ( Figures 8 and 8A) is crossed, from its front face 310 to its rear face 311, by a vertical passage slot 312 having the imprint of the key 4. On either side of this slot 312, are arranged, diametrically opposite, two threaded holes 315 intended to cooperate with the threaded rods screws 33.
  • notches 316a, 316b, 316c At the periphery of this front end disc, are formed three notches 316a, 316b, 316c, the functions will be explained below.
  • reference axis a longitudinal axis of symmetry slot 312, i.e. a vertical axis, oriented bottom up (bottom being on the bottom side of the board and the top being on the top side of the board)
  • the notch 316a lies in a direction substantially an angle of 20 ° with respect to this reference axis
  • the notch 316b is in a direction making substantially an angle of 70 ° with respect to this axis of reference
  • the notch 316c is substantially diametrically opposite to the notch 316a.
  • FIGS 9 and 9A show one of the washers conforming coding 30.
  • This washer 30 has two screw holes 305 homologated holes threaded 315 from the front end disc 31.
  • This coding washer 30 is crossed from its face front 300 to its rear face 301 by a passage of key 302 having a general cross-shaped profile but adapted to cooperate with the corresponding part of the paneton 40 of key 4.
  • each washer has a passage 302 having a profile adapted to its position in the internal block 3 and corresponding to the part of the paneton with which it will cooperate. All of the profiles of the passages 302 of all these washers 30 defines then a profile combined with that of the panetons 40 of key 4 and actually defines a coded combination that does not allow that the introduction of the key whose paneton presents the conjugate profile.
  • FIGS. 10 and 10A illustrate the intermediate disc 34 of the internal block 3.
  • the key passage 342 of this intermediate disc has a cross-shaped profile with substantially equal branches.

  • This intermediate disc is interposed between two coding washers, preferably substantially halfway between the two front and rear end discs. It thus makes it possible to ensure greater cohesion of the stack of coding washers and thereby make any attempt to twist them more difficult. It can also make it possible to oppose greater resistance to the possible drilling of the internal block.
  • transverse notches 45 key spanners will cooperate with the cross profile of passage 342 of this intermediate disc to be able to admit the panetons of this key first to the rear end disc and then to authorize their rotation.
  • the depth of transverse notches depends on the length of the branches profile of passage 342.
  • the longitudinal position of these transverse notches depends on the position of the intermediate disc in the stack of coding washers.
  • Figures 11 and 11 A show the end disc rear 32 of the internal block 3.
  • the passage slot 322 is horizontal.
  • two housings are provided screws 325, tapered, hole counterparts 305 and 315. These housings 325 are suitable for housing the heads 330 of the screws 33 and flare from the front face 320 of the disc 32 to its rear face 321.
  • This rear end disc has two studs 328, located on the front face 320, and projecting substantially perpendicular to it. These studs are arranged substantially along the transverse axis of symmetry of the slot 322 and are also arranged substantially symmetrically about the axis middle longitudinal of this passage slot 322.

  • Figures 12 and 12A illustrate the terminal disc 22 having its passage slot 222 passing through it in part from its front face 220 to its rear face 221. This passage slot is horizontal. On the face before 220, in its upper part, a hole is made blind 223, counterpart of housing 323 and in which is intended to fit finger 324 in order to secure in rotation the internal block with the socket.
  • indentations 316a, 316b, 316c and counterparts remove uncertainty on the vertical orientation of the passage slot 312.
  • those skilled in the art will understand that it is quite possible to represent these different discs and washers by rotating them, for example 180 ° around an axis perpendicular to their plane medium, due to the symmetry of revolution of the device lock.
