Definitions

  • the present invention relates to a disengageable rotor lock intended in particular to equip a lock for a motor vehicle.
  • It relates more particularly to a lock of the type comprising a rotor swiveling in an intermediate stator, itself pivoting in a fixed stator generally constituted by the body of the lock.
  • the lock comprises, in a manner known per se, locking members such as pairs of pistons or flakes cooperating with the rotor and the intermediate stator to secure them in rotation in the absence of a key or in the presence of a non-conforming key and release the rotor relative to the intermediate stator after insertion of the conforming key.
  • the bolt further comprises a control member of a lock such as a lever or thresher and means making it possible to make the rotor of said control member only after rotation of the rotor independently of the intermediate stator, that is to say only in the presence of a compliant key.
  • a control member of a lock such as a lever or thresher and means making it possible to make the rotor of said control member only after rotation of the rotor independently of the intermediate stator, that is to say only in the presence of a compliant key.
  • Such locks with disengageable rotor have the important advantage, from the point of view of safety, of not being able to be forced into rotation, the force rotation having the result, on the one hand, of leaving the rotor and the intermediate stator integral and , on the other hand, to make inactive the means for securing the rotor with the control member of the lock and therefore not to cause its actuation.
  • Document FR-A-2 631 067 describes a lock in which it is no longer the rotor which slides axially but a part integral in rotation with said rotor. Such a part is of a complex design because it must not only be integral with the rotor but include cam means so as to cause its axial sliding by rotation of the rotor.
  • such a lock In addition to an equally large axial size, such a lock must include erasable indexing means of the intermediate stator with the body, indexing means which require additional parts and therefore increase the cost of the assembly.
  • a disengageable rotor lock of the type comprising a rotor swiveling in an intermediate stator, itself pivoting in a fixed body, locking members such as pairs of pistons or flakes cooperating with the rotor and the intermediate stator to secure them in rotation in the absence of a key or in the presence of a non-conforming key and release the rotor relative to the intermediate stator after introduction of the conforming key, the lock further comprising a control member a lock, such as a lever or thresher and means for securing the rotor to said control member capable of securing only after rotation of the rotor independently of the intermediate stator, lock characterized in that the means for securing comprise a pusher integral in rotation with the intermediate stator and capable of sliding radially in said stator under the action of cam means provided on the rotor, the pusher cooperating by a rib with a control finger which can slide radially in the control member, it is integral in that the means for securing comprise a pusher
  • the lock according to the invention comprises a fixed stator or body 10 generally having the shape of a cylinder comprising a central bore 22.
  • the rear of the body 10 (on the left in FIG. 1) has a cylindrical collar 24, in which a radial slot 26 is formed, delimited by two recesses 28, 28 ′ formed of material on the collar 24.
  • the bore 22 of the body 10 is intended to receive an intermediate stator 12 which can rotate in the body 10.
  • the stator 12 is also generally in the form of a cylindrical barrel with a central bore 30.
  • the rear face 32 of the stator 12 is extended by two lateral wings 34,34 'having inside two circular recesses 36,36' symmetrical and diametrically opposite.
  • the bore 30 of the intermediate stator is intended to receive a rotor 14 which can rotate in said intermediate stator 12.
  • the rotor 14 generally has a cylindrical shape extending at the rear by a cylindrical part 42 of smaller diameter.
  • the rotor 14 also comprises cam means 44 constituted in the example represented by two lateral tabs 46,46 'symmetrical and diametrically opposite and whose lower faces 48,48' are planar and constitute a diameter of the rotor 14.
  • the ends 50.50 ′ are rounded so as to fit into the circular recesses 36.36 ′ of the intermediate stator 12, which will constitute guide surfaces for the cam means 44 during the rotation of the rotor (see figure 2).
  • the intermediate stator 12 and the rotor 14 include locking members such as couples of pistons or flakes to secure them in rotation in the absence of a key or in the presence of a non-conforming key and release the rotor 14 in rotation relative to the intermediate stator 12 after introduction of the conforming key.
  • locking members which are not part of the present invention, have not been shown.
  • the rotor 14 includes a key channel 52.
  • the lock comprises means for disengaging the rotor 14 consisting, on the one hand, of a plunger 16 and, on the other hand, of a control finger 18.
  • the plunger 16 is generally in the form of a washer with an oblong central hole 54 for the passage of the rear part 42 of the rotor.
  • the pusher 16 must not only be integral in rotation with the intermediate stator 12, but must be able to slide radially therein.
  • the pusher 16 comprises two parallel flanks 56, 56 ′ intended to cooperate with the internal surfaces of the lateral wings 34, 34 ′ located behind the intermediate stator 12.
  • two vertical ribs 60,62 are formed as a matter of material, the vertical rib 62 being connected by two cylindrical ribs 64,64 'adjacent to the oblong hole 54 with two horizontal ribs 66,66 ', whose upper faces 68,68' are aligned along the diameter corresponding to the lower faces 48,48 'of the cam means 44 of the rotor 14 ( Figures 2 and 5).
  • the front face 58 of the pusher 16 comes into contact with the rear face 32 of the intermediate stator 12 and the vertical ribs 60,62 penetrate into the grooves 38,40 respectively.
  • the cooperation of the parallel sides 56, 56 ′ of the pusher 16 with the internal surfaces of the wings 34, 34 ′ of the intermediate stator 12 constitute the means of securing them in rotation
  • the cooperation of the ribs 60, 62 with the grooves 38, 40 constitute the means of radial sliding of the pusher 16 in the intermediate stator 12.
  • the rib 62 of the pusher 16 has, relative to the outer periphery, a projection 70 with an end 72 having an axial notch 74 whose role will be explained further.
  • the radial size of the pusher 16 that is to say the distance D, between the external faces 76,72 of the ribs 60,62, is at most equal to the external diameter of the intermediate stator 12.
  • the control finger 18 has in its central part a shape generally identical to the pusher 16.
  • An oblong hole 78 allows the passage of the rear part of the rotor 42.
  • Parallel radial sides 80, 80 ' constitute, with the internal surfaces of the lateral wings 34, 34 ′ of the intermediate stator 12, the means for securing it in rotation as for the pusher 16.
  • the control finger 18 has at its upper part, an axial stud 82 of generally parallelepiped shape, the end of which comprises a key 84 (FIG. 1c).
  • the lower part of the control finger 18 comprises a tab 86, in the form of a square, the upper face 88 of which has an axial protuberance 90 of shape complementary to the axial notch 74 of the pusher 16.
  • a housing 94 which, as can be seen in particular in FIG. 2, is intended to receive a return spring 96.
  • control finger 18 comes to bear on the pusher 16 so that its protuberance 90 comes to cooperate with the notch 74 of the pusher 16 (FIG. 2) to constitute means of erasable angular indexing of the intermediate stator 12, rotor 14 relative to the body 10.
  • the lock also includes a control member or lever 20 in the general form of a cylindrical barrel having at its center a hole 98 intended to allow the rear part 42 of the rotor 14 to pass.
  • the cylindrical barrel is extended radially by a wing 100 of triangular shape at the end of which is formed an orifice 102 intended to receive, for example, the end of a mechanism for controlling a lock (not shown).
  • the lever 20 has two diametrically opposite grooves 104, 106 (FIG. 1b) intended to receive the axial stud 82 respectively, and the tab 86 of the control finger 18.
  • the groove 106 contains the return spring 96 (see FIG. 2 for example) .
  • control finger 18 is integral in rotation with the lever 20.
  • FIG. 2 illustrates the various components of the latch in the rest position.
  • the cam means 44 of the rotor 14 are supported on the horizontal ribs 66, 66 ′ of the plunger 16, said plunger 16 being inscribed in the external diameter of the intermediate stator 12 and integral with that in rotation.
  • the key 84 of the axial stud 82 of the control finger 18 is inside the radial groove 26 of the body 10 (FIG. 4). Thus, the finger 18 and therefore the lever 20 are immobilized in rotation relative to the body 10.
  • the rotor 14 is integral in rotation with the intermediate stator 12 by its locking members such as pistons or flakes. Any force on the rotor 14 rotates the intermediate stator 12 and therefore the pusher 16, the notch 74 of which escapes the protuberance 90 of the control finger 18. No rotation drive of the lever 20 and therefore no actuation of the lock can take place, the key 84 of the finger 18 still being inside the groove 26 of the body 10. There is simply an angular de-indexing of the rotor 14, intermediate stator 12 relative to the body 10.
  • the movement of the control finger 18 causes an output of the key 84 from the groove 26 of the body 10, which is thus no longer integral in rotation with the rotor 14 and the intermediate stator 12.
  • a complementary rotation of the conforming key rotates the intermediate stator 12, rotor 14, plunger 16 and lever 20 assembly: the lock opening mechanism is actuated.
