Definitions

  • the present invention essentially relates to a safety device allowing the control of any lock mechanism and capable of achieving a blocking of the barrel in the event of an attempt to force it by pushing it in using a tool or of a false key.
  • This invention also relates to a lock mechanism equipped with such a safety device.
  • Safety devices are already known which allow the control of a lock mechanism by means of a driving element which is axially coupled to a barrel rotatably mounted in a body and actuable by a key.
  • the main object of the present invention is to remedy the above drawback by proposing a safety device which blocks or locks the barrel in the body in the event of an forcing attempt.
  • the subject of the invention is a safety device for controlling a lock mechanism by means of a driving element which is axially associated with a barrel rotatably mounted in a body and actuable by a key, characterized in that the barrel or the driving element comprises deformable lugs capable of blocking the barrel-driving element assembly in rotation in the body under the effect of a forcing action by depressing the sliding barrel under the action of 'a tool or a false key.
  • the aforementioned tabs are integral with the barrel and are received in notches provided on the periphery of the driving element.
  • the aforementioned tabs are integral with the driving element and are capable of cooperating with at least one safety member, such as for example a chuck.
  • this spigot In the event of forcing by pressing in the barrel, this spigot, causing the deformation of the tabs, locks the barrel-entraining element assembly in the body, while in the event of actuation of the barrel by the appropriate key, said spigot cooperates with the tabs to allow the rotation of the barrel-driver element assembly in the body.
  • the aforementioned chin, mounted sliding in the barrel is held by a spring in a recess or the like formed on the internal periphery of the body so as to thus prevent any rotation of the barrel in the body, while in the active or actuating position of the barrel by the key which controls the linings or the like, said chin, released by the alignment of said linings, moves towards them by cooperation with the 'free and tapered end of the legs to finally allow the rotation of the barrel-driver element assembly in the body.
  • a spring arranged axially between the driving element and the barrel, and another spring arranged axially between said barrel and the linings.
  • a safety device essentially comprises a barrel 1 rotatably mounted in a body 2 and actuable by a key (not shown).
  • the barrel 1 is axially coupled to a driving element 3 capable of actuating any lock mechanism (not shown), under the effect of the rotation of the barrel 1 caused by the key.
  • the key When the key is introduced into the body 2 through the inlet 4, it causes the linings or the like (not shown) of the barrel 1 to be aligned, so as to allow the latter and the driving element 3 to rotate in the body 2, at the same time as the thrust by the key of a small piston 5 urged by a spring 6 and comprising at its end an end piece 7 meshing with the lock mechanism.
  • a chin here having the shape of a small cylindrical rod and normally cooperating with a groove formed in the internal periphery of the body 2 to prevent the barrel 1 from rotating in this body in the absence of the introduction of the key in the barrel 1.
  • the barrel 1 is provided with deformable lugs P which extend substantially parallel to the axis of the barrel.
  • These legs P are in reality part of a ring 8 fixed on the barrel 1, at one end of it, but it could perfectly well, without departing from the scope of the invention, ensure that the legs P are integral with the barrel 1.
  • the legs P are tapered from where they originate on the ring 8 to their free end, and they are received in notches 9 provided on the outer periphery of the element coach 3 and which are clearly visible in FIG. 4. These notches 9 cooperating with the legs P each have a shape of a ramp, as can be seen clearly in FIGS. 1 and 3.
  • the ring 8 carrying the tabs P also comprises two pins 10 slidingly entering the driving element 3 and ensuring the coupling in rotation of this driving element with the barrel 1. But these pins 10 are in no way obligatory since the coupling in rotation in question could quite simply be ensured by the cooperation of the legs P and the notches in the form of a ramp 9 of the driving element 3.
  • the barrel 1 will be keyed in a way, by the lugs P on the body 2 and the rotation of the barrel 1 - driving element 3 assembly in the body 2 will be definitively prohibited. In other words, any axial forcing action on the barrel 1 will necessarily cause a positive and final locking in rotation of the aforementioned assembly in the body 2 of the safety device.
  • the legs P are integral with the driving element 3 axially coupled in rotation to the barrel 1.
  • the legs P can cooperate with at least one safety member, such as for example a spigot 12 mounted to slide in the barrel 1 orthogonally to its axis, and constantly stressed by a spring 13 (FIG. 11) in a recess or recess 14 formed in the periphery of the body 2.
  • the jib 12 in the event of forcing by pressing in the barrel 1, locks the barrel 1 - driving element 3 assembly in the body 2, while in the case of normal actuation of the barrel 1 by the appropriate key 15 (FIG. 7), said chin cooperates with the legs P to allow the rotation of the aforementioned assembly in the body 2.
  • the barrel 1 comprises, as known per se, a plurality of relatively mobile linings 16 and each comprising a notch 17.
  • the introduction of the key 15 into the barrel 1 will allow alignment notches 17 of all the linings 16, so that the chin 12 can move towards these linings by entering the notches 17, and this thanks to the tapered ramp-shaped end 18 of the legs P on which the chin can mount 12.
  • the chin 12 having come out of its notch 14, the barrel assembly 1 - driving element 3 can rotate in the body 2.
  • a spring arranged axially between the driving element 3 and the barrel 1.
  • Another spring 20 is axially arranged in the barrel 1 between the bottom of this barrel and the linings 16 to return them to their initial position after removal of the key 15.
  • the barrel 1 When the key 15, as can be seen in FIG. 7, is introduced, which causes the notches 17 of the linings 16 to be aligned, the barrel 1 will be pushed axially by virtue of the erasure of the flange 12 by the ramp 18 of the 'driving element 3, the displacement of said chin perpendicular to the axis of the barrel 1 being authorized by the prior alignment of the notches 17 into which penetrates the end of the chin opposite to that cooperating with the legs P.
  • the chin 12 In the event of an attempt to force the barrel 1 by pressing in using a false key or a tool F, the chin 12 cannot be erased when entering the linings 16, and will force on the legs P of the driving element 3.
  • the end of the legs P comprising the ramp 18 deforms elastically and radially outward to come to be housed in the groove 11 on the internal periphery of the body 2.
  • any rotation of the barrel 1 and of the driving element 3 in the body 2 is positively prevented. This means that there is blockage of the barrel assembly 1 - driving element 3 in the body 2, and that consequently the lock mechanism cannot be actuated.
  • a safety device has therefore been produced according to the invention, the active parts of which are blocked or locked together during an attack on the barrel with a false key or any forcing tool.
