Definitions

  • the present invention relates to a safety cylinder intended for the operation of a lock, said cylinder comprising a safety barrel arranged inside a protective sleeve intended to protect the barrel against attempted break-ins.
  • a safety barrel intended for the maneuver a lock consists of a stator inside which can turn a rotor, the rotor having a key housing; ways to keying are provided between the rotor and the stator, so that the declaving occurs when the appropriate key is inserted in the key housing.
  • the rotor can therefore rotate relative to the stator and drive a rotating member which causes the operation of the lock with which the barrel is associated.
  • Ways of keying interposed between the rotor and the stator are generally arranged in planes which are radial with respect to the rotor.
  • French patent 2,690,192 has already proposed place an anti-drilling disc in front of the key entry of a rotor safety barrel.
  • This pellet is free to rotate inside a protective sleeve into which the safety barrel to be protected is inserted; the patch is crossed by a slot allowing the introduction of the key to the key housing of the barrel rotor.
  • the drill drives the pellet in rotation, which prevents drilling.
  • such a tablet must be likely to resist impact, otherwise it would be enough to break the pellet, extract the pieces out of the protective sleeve and then attack the barrel rotor with a drill.
  • the anti-drilling tablet thus proposed does not have the expected effectiveness due to the fact that the inserts are put in place by the rear face of the burglar-resistant disc, so that if they are exposed by a start of drilling, they can be chased with a pin punch, the barrel retreating under the blows transmitted by the pin punch and the inserts then falling between the face front of the barrel and the rear face of the pellet. It should be noted just remove one of the inserts from the pellet described in the aforementioned patent so that there is sufficient passage to allow the drilling. To avoid this inconvenience, one could imagine brazing the inserts in the pellet, but, in this case, the cost price of the tablet increases considerably due to labor costs of work.
  • the tablet described in the French patent 2,690,192 has two external diameters in its thickness, the shoulder between the two diameters allowing the retention of the tablet inside the protective sleeve.
  • the connection between two diameters is made at a right angle and is in the vicinity immediate pastille inserts; this results in a weakening of the patch at the connection angle.
  • the object of the invention is to improve the burglar-proof characteristics a safety cylinder.
  • the invention relates to a safety cylinder for lock having improved burglary protection, said cylinder comprising a safety barrel arranged inside a chamber formed in a protective sleeve, said chamber being delimited by a bottom on the side of the front face of the protective sleeve, said barrel comprising a rotor capable of rotating around its axis at inside a stator, keying means being arranged between rotor and stator and can be operated by a key inserted in a rotor key housing, said protective sleeve bearing on its front face, facing the rotor, an anti-drilling pad in which is provided a key passage.
  • the invention relates to a safety cylinder of the type defined above, in which the anti-drilling pad includes, on both sides of the key passage, at least one pellet insert made of a material with a hardness greater than that of material constituting the pellet, this cylinder being characterized by the fact that each pad insert constitutes a pin arranged substantially parallel to the plane of the key passage and substantially perpendicular to the axis of the patch.
  • the anti-drilling tablet is free to rotate and has a front face facing the outside, of smaller diameter than its rear face facing the barrel rotor, the outer side wall of the pellet comprising a frustoconical zone between its front and rear faces: the front face of the protective sleeve surrounds the anti-drilling disc and the presence of the frustoconical zone makes it possible to significantly strengthen the resistance to deformation of the front face of the protective sleeve in the area where the pellet increases in diameter; indeed if in this area the front face is too thin, it is possible to deform the face frontal enough to open a hole allowing the extraction of the anti-drilling tablet.
  • the shape of the frustoconical area above proposed allows the drill to be deflected when the drilling attack takes place at the right of the said zone.
  • the patch has, on its rear face, a peripheral flange which, preferably does not connect directly to the frustoconical area and which constitutes an additional retention element of the pellet.
  • the pellet includes a pin each side of the key passage, the axes of the two pins being symmetrical with respect to the mean plane of the key passage; the axes pins are preferably arranged relative to the area frustoconical of the pellet, on the side of the rear face of said pellet.
  • the rear face of the pad has a recess making it possible to accommodate the front face of the barrel rotor, which projects slightly from the face front of the stator;
  • the front face of the patch is curved, in particular in the shape of a spherical cap, and has its convexity towards the outside;
  • the area of the front face of the protective sleeve, which surrounds the front face of the patch forms a depression, by example of a conical shape, the concavity of which faces outside.
  • the safety cylinder of the previously defined type is characterized by the fact that a plurality of protector inserts is placed in a crown around the anti-drilling tablet, in housings in the sleeve protector, at the bottom of the room where the barrel is housed.
  • a plurality of protector inserts is placed in a crown around the anti-drilling tablet, in housings in the sleeve protector, at the bottom of the room where the barrel is housed.
  • the inserts of protector have a frustoconical shape, the small base of which is directed towards the front of the protective sleeve.
  • This advantageous form of inserts to prevent them from being released from their housing; indeed, if we insert balls in the drilling area, the drill which happens on a broken ball, but the ball is thus exposed and can be extracted from its housing, which is not the case with an insert frustoconical whose large base is arranged opposite the face front of the protective sleeve.
  • all of the protector inserts are integral with a circular ring; indeed, the installation of inserts frustoconical in the bottom of the protective sleeve chamber is difficult to achieve with an automatic assembly machine.
  • the ring of the protector inserts is put in place on a cylindrical surface of the anti-drilling tablet; advantageously, if an anti-drilling tablet is used according to the first characteristic of the invention, as defined above, the cylindrical reach can be that in which the two open pellet pin bores.
  • the protector inserts are not put in places that opposite the angular barrel sectors comprising the keying means to be protected.
  • the sleeve chamber protector where the barrel is located is cylindrical and has, on its side wall, parallel to its generator direction, grooves allowing the installation of the ring at the bottom of the chamber of the protective sleeve by sliding inserts in said grooves towards the bottom of the chamber, a sheath being interposed between the stator of the barrel and the sleeve chamber on at least part of the sector occupied by said grooves.
  • the scabbard may have on its external face of the ribs complementary to the grooves of the chamber, which allows its easy positioning on an angular sector determined from the room to the right of the protector inserts.
  • the scabbard may have, at its end intended to come from the side of the face front of the sleeve, a flat crown positioned around a cylindrical bearing surface of the anti-drilling disc, said crown being in support on the bottom of the chamber and having as external contour the internal cross section of said chamber; in case we use a anti-drilling tablet according to the first characteristic of the invention, as defined above, the flat crown can be positioned around the flange of the patch.
  • the sleeve 1 has a front face 1 a and an external flange 1 b which surrounds its rear zone, that is to say the zone which is opposite to the front face 1 a .
  • the protective sleeve 1 externally has a generally cylindrical shape and its front face is that which appears outside a door which is equipped with such a safety cylinder.
  • the protective sleeve is, at its front face, surrounded by a counter plate 2, which is kept applied to the door 3 by three screws 4 bearing on the lock 5 of the lock 6 with which the safety cylinder according to the invention is associated. 4 screws pass freely through the collar 1b of the protective sleeve 1 and cooperate with bores in the thickness of a tube 2 welded to the rear against the plate 2. Furthermore, the edges of the counter plate 2 are held by screw 4 has also taking support on the Foncet 5 and screwing into the terminals 2b which are secured against the plate 2 to the back thereof.
  • the protective sleeve 1 internally defines a chamber 7 of cylindrical shape but of non-circular cross section. Inside the chamber 7, is arranged the stator 8 of a safety barrel, whose rotor 9 causes, by its rear end, the operation of the lock 6, the front end of the rotor being that which is neighboring of the front face 1 a of the protective sleeve 1.
  • the stator 8 of the barrel is secured, by its rear face, to the pin 5 of the lock 6.
  • the chamber 7 is open at its rear end and, on the side of the front face 1 a , it has a bottom 7 a .
  • the axis of the rotor 9 is offset by 4 mm relative to the axis of the stator 8.
  • the front face of the protective sleeve 1 has a circular orifice where the front part of a designated anti-drilling disc is arranged. by 10 as a whole.
  • the pad 10 includes a key passage 11, which allows the key associated with the safety cylinder to pass through the pad 10; it is delimited externally by a side wall made up of four successive parts: a cylindrical front part 10 b , which is connected to the front face 10 a of the patch; a rear part 10 e , which constitutes a circular peripheral flange; a frustoconical zone 10 c , which connects with the cylindrical part 10 b ; and a part 10 d , which constitutes a cylindrical bearing surface connecting the conical part 10 c to the base of the collar 10 e .
  • a recess 12 is formed on the rear face of the flange 10 e and is intended to receive the front face of the rotor 9, front face which is slightly projecting relative to the front face of the stator 8.
  • two blind holes 13 a , 13 b are arranged head to tail in the cylindrical surface 10 d , the axes of these two bores being symmetrical with respect to the mean plane of the passage of key 11.
  • pins are inserted, respectively 14 a , 14 b , and the pins are held in place by a slight crimping made in 15.
  • the pins 14 a , 14 b are made of a material harder than that of the anti-drilling pad, this material can be brittle: it can be, for example, highly hardened steel, carbide or ceramic.
  • the front face 10 a of the pad 10 is disposed at the bottom of a frustoconical depression 1 c , which has the front face 1 a of the protective sleeve 1.
  • the part 10 b of the pad 10 projects very slightly at the bottom of the depression 1 c , but the material of the sleeve 1 follows the outline of the parts 10 b , 10 c of the patch 10 and constitutes a retaining lip of said patch, this lip having, due to the frustoconical shape of the part 10 c , a increasing thickness, when following its contour from the front face 1a in the direction of the interior of the protective sleeve.
  • frustoconical housings 16 have been formed, the small bases of which are shaped according to a spherical cap and are arranged on the side of the front face 1 a of the protective sleeve 1.
  • the housings 16 are arranged in crown around the axis of the rotor 9, over a sector of approximately 260 °, said sector being symmetrical with respect to the plane which contains the axes of the rotor 9 and the stator 8.
  • inserts are inserted of protector 17 having a shape corresponding to that of the housings 16, the inserts 17 therefore comprising a frustoconical side wall and an end wall in the form of a spherical cap.
  • All the inserts 17 are arranged in a crown on the outer edge of a circular ring 18, all of the inserts 17 and the ring 18 constituting a ring 19.
  • the ring 18 is housed in a recess 20 of the protective sleeve 1, said recess being situated immediately behind the zones where the parts 10 b and 10 c of the pad 10 are placed.
  • the ring 18 of the ring 19 is therefore placed around the cylindrical surface 10 d of the pad 10 and the peripheral flange 10 e of the patch 10 comes to bear against the ring 18 of the ring 19.
  • a sheath 22 is therefore put in place, which has the shape of a cylindrical sector, the inner wall of which has a circular cross section centered on the axis of the stator 8 and the outer wall of which has ribs 23 having profiles complementary to that of the grooves 21.
  • the sheath 22 extends over approximately 180 ° around the axis of the rotor and is provided, at its end intended to come against the bottom 7 a of the chamber 7, of a flat crown 24, the thickness of which is substantially equal to that of the peripheral flange 10 e ; the flat crown 24 delimits a circular orifice whose diameter is equal to that of the peripheral flange 10 e which is therefore housed inside the crown, this orifice therefore being centered on the axis of the rotor 9.
  • a its lower part, the crown is formed by the front end of the sheath 22 and, at its upper part, it is delimited by a circular external contour centered on the axis of the stator 8.
  • the mounting of the safety cylinder which has just been described is extremely simple: the pad 10 is first assembled in the ring 19; from the rear opening of the chamber 7, this sub-assembly is then put in place in the front part of the protective sleeve 1, so that the front face 10 a is flush with the bottom of the depression 1 c , the ring 18 of the ring 19 coming to bear at the bottom of the recess 20.
  • the sheath 22 is then put in place, said sheath coming to lock the pellet 10 in position by resting on the rear of the peripheral flange 10 e , the crown 24 from surrounding said peripheral flange.
  • the barrel is then put into place inside the chamber 7, the front face of the rotor 9 coming to engage in the recess 12 of the pad 10.
  • This security cylinder is particularly effective against break-ins for the various reasons which have been previously detailed.
  • a piercing action acting directly on the pad is hampered by the fact that this pad is free to rotate; if, nevertheless, the drill enters the pellet, it breaks when it comes into contact with the pins 14 a , 14 b . If one seeks to pass on the side of the anti-drilling pad to reach the rotor / stator keying means at an angle, the drill bit falls on the inserts 17 and breaks, since the ring 19 is made of a very hard of the same type as that of pins 14 a , 14 b .
  • Maintaining the barrel in abutment against the peripheral flange 10 e and the crown 24 is obtained by virtue of the fact that the barrel is carried by the bolt 5 and that the protective sleeve 1 is subjected to the action of springs (not shown), which are inserted between the tube 2 a and the collar 1 b of the protective sleeve 1.
  • springs (not shown), which are inserted between the tube 2 a and the collar 1 b of the protective sleeve 1.
  • the greater or lesser compression of these springs makes it possible to adapt the assembly to doors of slightly different thicknesses for a barrel stator of given length, by playing on the play existing between the collar 1 b and the tube 2 a .
  • the extraction of the protective sleeve 1 towards the outside is limited by the stroke existing between the tube 2 a and the collar 1 b .
