Definitions

  • the present invention relates to a disengageable rotor lock.
  • the invention relates more particularly to 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 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 to release the rotor in rotation relative to the intermediate stator after introduction of a conforming key, and of the type comprising a member indexing the intermediate stator relative to the fixed body.
  • indexing member is produced in the form of an arm arranged in a longitudinal housing formed in the peripheral wall of the intermediate stator in which it is mounted mobile, pivoting, in the vicinity of one of its ends, around an axis perpendicular to the axis of the bolt, between an indexing position, towards which it is spring-loaded, and a retracted position in which it is at least partially erased in the housing, against the elastic return force.
  • the indexing arm is produced in the form of a lever which is pivotally mounted in the vicinity of one of its ends with respect to the intermediate stator and a helical compression spring is provided which cooperates with the internal radial face of the lever and which bears against a bearing surface formed in the bottom of the housing to elastically urge the indexing lever towards its indexing position.
  • This design is particularly complex insofar as it requires providing means of articulation of the end of the lever relative to the intermediate stator as well as an independent return spring of very small dimension, these two components must be assembled and put in position precisely in the latch when assembling the components of the latter. Such complexity in particular does not make it possible to automate assembly operations.
  • Document EP-A-0520 904 illustrates a lock according to the preamble of claim 1 in which the indexing member consists of elastic tabs formed integrally with the intermediate stator, which complicates its preparation.
  • the invention as defined in claim 1 proposes 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 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 to release the rotor in rotation relative to the intermediate stator after introduction of '' a conforming key, and of the type comprising an indexing member of the intermediate stator relative to the fixed body produced in the form of an arm arranged in a housing longitudinal formed in the peripheral wall of the intermediate stator in which it is mounted movable between an indexing position, towards which it is resiliently recalled, and a retracted position in which it is erased at least partially in the housing, against an elastic restoring force, the indexing arm being produced in the form of a beam which can be elastically deformed in bending to occupy the
  • the lock illustrated in particular in Figure 1 comprises a rotor 10 which is pivotally mounted in an intermediate stator 12, the latter itself being pivotally mounted in a fixed body 14 of the lock.
  • the rotor 10 has a longitudinal key introduction channel 16 into which radial slots 18 open.
  • the intermediate stator has longitudinal slots intended to receive the ends of flakes which are housed in the radial slots 18.
  • the flakes which constitute the locking members between the rotor 10 and the intermediate stator 12 can be replaced by any type of 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.
  • the rotor 10 comprises, at one of its ends, a lug 24 intended to cooperate with a control member 26 whose axis 28 is integral with an operating lever 30 connected to an actuating rod (not shown) of the lock mechanism which equips the door.
  • FIGS. 2 to 5 Reference will now be made to FIGS. 2 to 5 for the detailed description of the first embodiment of the indexing member of the intermediate stator 12 relative to the fixed lock body 14.
  • the indexing member 32 is in the form of a single element, molded in plastic material, produced in the form of a beam arranged in a longitudinal housing 33.
  • the beam has a longitudinal body 34 which extends parallel to the axis X-X of the lock and whose section is substantially rectangular.
  • the left end 36 of the body 34 of the beam 32 is embedded and is for this purpose received in a recess formed in the peripheral wall 13 of the intermediate stator 12 into which it opens and which has a bottom the recess 38 against which the internal radial face 40 of the embedded end 36 of the beam 32 bears.
  • the external radial face 42 of the embedded end 36 which is continuous along the body 34 of the beam, is in contact with the internal peripheral wall 15 of the fixed body 14 of the lock.
  • the embedded end 36 is thus held radially in both directions while the beam is immobilized longitudinally by means of a finger.
  • retainer 44 made integrally with the body 34, which extends radially outward and which is received in a hole of complementary shape 46 formed in the peripheral wall 13 of the intermediate stator 12 and which opens into the latter.
  • the indexing beam is illustrated in Figures 2 and 3 in solid lines in its rest position which it normally occupies and which corresponds to the indexing position of the beam.
  • the beam 32 has, in the vicinity of its free end 46, an inverted V-shaped projection which extends radially outwards from the external radial face 42 of the beam.
  • the projection 48 is received in a longitudinal groove 58, of complementary profile in the form of an inverted V, formed in the internal wall 15 of the fixed body 14 of the latch.
  • the free end 46 of the beam 32 comprises, on its internal radial face 40, a locking heel 60 which, in the indexing position, extends inside the housing 33, in which the body 34 extends of the beam 32, opposite a window 62 formed in the bottom of the housing 33 and which opens into the internal wall 11 of the intermediate stator 12 opposite a notch 64 formed in the peripheral surface 9 of the rotor 10.
  • the indexing beam 32 can be bent, from its indexing position, and against the proper elasticity of the beam, to occupy a retracted position, illustrated in dotted lines in FIG. 2, in which the heel 60 is received in the notch 64.
  • the indexing member 32 occupies the position illustrated in solid lines in FIG. 2. In this position, the projection 48 is received at inside a longitudinal groove 58 of the fixed body 14 and the heel 60 is located inside the housing 33.
  • the heel 60 of the indexing member 32 is no longer vis-à-vis the notch 64 but is flush with the solid peripheral surface 9 of the rotor 10 thus preventing any inadvertent disengagement, by example when the conforming key is in abutment, at the end of the rotor rotation stroke.
  • the locking members keep the rotor 10 integral in rotation with the intermediate stator 12.
  • the indexing member 32 produced in accordance with the teachings of the invention is of particularly simple design insofar as it is a single piece molded from plastic material which is placed in position during the assembly of the lock, by putting its end 36, 44 in the recess 38 and the hole 46, without any additional operation for mounting a return spring being necessary.
  • This second embodiment differs essentially from the previous embodiment in that the indexing beam 32 is not embedded in the vicinity of its first longitudinal end 36 but is produced in the form of a simple beam resting on its two opposite ends.
  • the left end 36 of the body 34 of the beam 32 is pressed against a bottom facing 39 of the housing 33, while the right end 41 of the body 34 of beam 32 is pressing against a corresponding bottom portion 43 of the housing 33.
  • the bottom portions 39 and 43 are delimited longitudinally by the window 62 formed in the bottom of the housing 33.
  • the external radial face 42 of the left end 36 of the beam which is continuous along the body 34 of the beam, is in contact with the internal peripheral wall 15 of the fixed body 14 of the latch.
  • the end 36 is thus held radially in both directions.
  • the indexing beam 32 illustrated in FIGS. 6 to 10 is therefore thus liable to deform elastically in its central part.
  • the projection 48 and the heel 60 are both arranged in the central part of the indexing beam 32, that is to say in the part liable to deform elastically between the opposite end supports.
