Definitions

  • the present invention relates generally to a disengageable rotor lock.
  • Such a lock consists of a rotor swiveling in a sleeve or intermediate stator, said intermediate stator itself being able to pivot in a fixed body.
  • Locking members such as pairs of pistons or flakes cooperate with the rotor and the intermediate stator so as to make them rotationally integral in the absence of a key or in the presence of a non-conforming key and to release the rotor in rotation by report to the intermediate stator when a compliant key is introduced.
  • Such a latch usually drives a control member of a lock by means of the means for securing the rotor to said control member, these securing means being implemented only when the rotor turns alone, independently of the intermediate stator.
  • 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.
  • An erasable indexing member may consist of a ball recalled by a spring, sliding in a blind bore of the stator and cooperating with a hole made in the body of the lock, as described and shown in the document FR-A- 2,583,813.
  • Document FR-A-2 631 067 describes such a body indexing consisting of a lever integral in rotation with the intermediate stator provided with a heel, housed in the rest position in a longitudinal groove in the body of the lock, said lever being biased towards the intermediate stator by a spring.
  • Document EP-A-0410 830 also describes such a member consisting of two diametrically opposite elastic tabs cooperating with recesses in the intermediate stator.
  • Such a configuration allows, with two separate parts, to perform the functions of angular indexing and rotor-stator connection.
  • a disengageable rotor lock comprising a rotor swiveling in an intermediate stator, itself pivoting in a fixed body, locking members such as flakes or pairs of pistons 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 a conforming key, first erasable indexing means of the intermediate stator relative to the body and second means for strengthening the rotor connection, intermediate stator in the presence of a non-conforming key, characterized in that the first and second means are constituted by at least one elastic tab made of material in a recess of the intermediate stator, each elastic tab comprising a circular branch connected to a radial branch.
  • the glitter lock shown in particular in FIG. 1 comprises a rotor 11, journalled in an intermediate stator 12, said intermediate stator 12 pivoting in a fixed body 13.
  • the rotor 11 has a longitudinal key channel 14, into which radial slots 15 open.
  • the intermediate stator 12 has slots longitudinal 16 intended to receive the ends of flakes 17 housed in the radial slots 15.
  • the flakes 17 which constitute the locking members between the rotor 11 and the intermediate stator 12 can be replaced by any known locking members such as pairs of pistons, levers etc.
  • the entire lock is intended to be fixed for example in a door handle of a motor vehicle 18 by any suitable means.
  • the rotor 11 has at one of its ends a lug 19 intended to cooperate with a control member 20 whose axis 21 is secured to an operating lever (not shown) for actuating the lock mechanism.
  • a compression spring 22 makes it possible to return the rotor 11 - intermediate stator 12 assembly to the rest position.
  • a torsion spring 23 returns the rotor 11 to the rest position after its rotation.
  • FIG. 3 describes in more detail the intermediate stator 12 which comprises, on the insertion side of the key, a cylindrical part 25 connected to a cylindrical flange 26 of larger diameter.
  • This flange 26 has at its periphery notches 27 intended to receive the fixing lugs 28 of a protective cover 29 (see FIG. 1).
  • a central bore 31 passes through the assembly of the intermediate stator and serves as a housing for the rotor 11.
  • the rear part 32 of the intermediate stator 12 has a recess 33 providing two flats 34,35.
  • the intermediate stator 12 comprises, formed in one piece, two elastic tabs 36 constituting on the one hand first erasable indexing means, on the other hand second means for reinforcing the rotor connection 11, intermediate stator 12 , in the presence of a non-compliant key.
  • Each elastic tab 36 comprises a circular branch 37, the outer face 38 of which is eccentric with respect to the inner face 39 of the body 13 (FIG. 2).
  • Each circular branch 37 is connected on the one hand to the flats 34, 35 and on the other hand to a radial branch 40 each having an external side with a rounded projection 41.
  • the radial branches 40 have a tapering section towards the axis of the intermediate stator so as to constitute on the side opposite to the projection 41 a heel 42.
  • each elastic tab 36 cooperates with a longitudinal groove 43 formed in the body 13.
  • the rotor 31 In line with the heels 42, the rotor 31 has a housing 44, the role of which will be explained below.
  • the elastic tabs 36 In the rest position, or in the event of the introduction of a conforming key, the elastic tabs 36 occupy the position shown in solid lines in FIG. 2: the heels 42 are flush with the external periphery of the rotor 11 and the projections 41 are inside. of the longitudinal groove 43 of the body 13 thus constituting the first erasable indexing means between the intermediate stator 12 and the body 13.
  • the locking members 17 are in concordance with the rotor 11, thus disengaging it in rotation from the intermediate stator 12.
  • the heels 42 of the elastic tabs are no longer vis-à-vis the housing 44 but are flush with the full external periphery of the rotor, which prevents any untimely disengagement, for example when the conforming key is in abutment, at the end of its rotation.
  • the locking members 17 keep the rotor 11 integral in rotation with the intermediate stator 12.
  • the projections 41 of the elastic tabs 36 escape from the longitudinal groove 43 and come to bear against the internal wall 39 of the body 19. Simultaneously their heels 42 penetrate into the housing 44 of the rotor 11 as shown in dashed lines in FIG. 2 and thus constitute the second means for strengthening the rotational connection of the rotor 11 with the intermediate stator 12. It is therefore the rotor 11 - intermediate stator 12 assembly which pivots in the body 13 preventing any actuation of the lock mechanism.
  • first and second means thus formed are particularly simple since they do not require any additional part.
  • the two legs 36 could be replaced by a single one, likewise the legs 36 could have a common heel 42.
