Definitions

  • the invention relates to an improved axial release lock for a motor vehicle lock mechanism.
  • the invention relates more particularly to a disengageable lock, in particular for a motor vehicle lock mechanism, of the type in which the lock comprises a fixed stator, a tubular intermediate sleeve which is rotatably mounted about its axis in the stator and which is axially fixed relative to the stator, a rotor which is rotatably mounted in the bushing, which is axially fixed in the bushing, and which comprises flakes movable radially under the action of a key intended to be introduced axially into the rotor, of the type in which the flakes are entirely retracted radially inside the rotor when the key is in conformity, so as to allow free rotation of the rotor relative to the sleeve and to the stator and thus allow the rotational drive of a lock control lever which is coupled to the rotor by means of a driver, of the type in which the rotor and the intermediate sleeve are b locked in rotation relative to each other by the flakes when the key is not in
  • a declutching mechanism on such a lock makes it possible to prevent it from being "forced". Indeed, if a dummy key, or any other flat tool of adequate shape, is introduced into the rotor, and if an attempt is then made to drive the rotor in rotation, the declutching mechanism allows the rotor and the intermediate sleeve to pivot freely inside the stator without excessive efforts being exerted on the flakes.
  • the glitter is likely to be deteriorated or to be retracted, in force, which then allows to unlock the lock without the conforming key.
  • the indexer consists of two balls which are received in two axial grooves formed in the internal periphery of the stator and which are intended to cooperate with ramps formed in the free end of the intermediate sleeve so that, when the intermediate bush is driven in rotation by the flakes of the rotor, the ramps of the bush cause the balls to move axially forward inside the grooves.
  • the balls forming the indexer then cause the displacement, axially forward, of a driver, against a return spring interposed between the control lever and the driver, which are linked in rotation.
  • the driver is in the axially advanced position, the latter is locked in rotation relative to the stator so that the control lever of the lock mechanism is also blocked, thus making it impossible to pick the lock.
  • the mechanism shown proposes the use of balls whose immobilization in rotation around the axis of the lock is ensured by their maintenance inside the grooves.
  • the balls are subjected to a force which tends to cause them to exit tangentially from the axial groove because they cooperate, by a first internal radial spherical cap, with the intermediate sleeve and in particular with the ramps of these, and, by a second external radial cap, with the grooves of the stator.
  • the balls are therefore subjected to each disengagement to a shearing force and the balls tend to damage the edges of the stator grooves as well as the ramps of the intermediate sleeve.
  • the present invention proposes a design in particular of the driver which allows an axial assembly of all the parts of the lock, assembly which can then be easily automated.
  • the invention provides a disengageable lock, in particular for a motor vehicle lock mechanism, of the type in which the lock comprises a fixed stator, a tubular intermediate sleeve which is rotatably mounted about its axis in the stator and which is axially fixed relative to the stator, a rotor which is rotatably mounted in the bushing, which is axially fixed in the bushing, and which comprises means for locking the rotor relative to the bushing, of the type in which the means of locking are retracted when a conforming key is inserted into the rotor so as to allow free rotation of the rotor relative to the sleeve and the stator and thus allow the rotary drive of a control lever of the lock which is coupled to the rotor by means of a driver, of the type in which the lock comprises an indexer which is axially movable between a rest position and a declutching position, under the effect of a rotation of the sleeve relative to the stator following the
  • FIG. 1 shows a rotary lock with a longitudinal axis A1 comprising declutching means in accordance with the teachings of the invention.
  • the lock 10 essentially comprises a rotor 12 which is mounted to rotate, around the axis A1, inside a stator 14, with interposition between the two of an intermediate socket 16.
  • the rotor 12 is intended to be driven in rotation using a key (not shown) introduced axially from rear to front inside the rotor 12 through a key entry 18 arranged in a transverse face.
  • rear 20 of the rotor 12, which face 20 is intended for example to be flush with the outside of a body panel (not shown) of the vehicle.
  • the front axial end 22 of the rotor 12 is intended to drive in rotation a control lever 24 of a lock mechanism (not shown) to authorize the locking and unlocking of an opening of the vehicle.
  • the rotor 12 is capable of driving the control lever 24 in rotation, only in the presence of a conforming key, by means of a driver 26 which is axially movable in the latch 10, under the action of a indexer 28, between a engaged position in which it rotates the rotor 12 and the control lever 24, and a disengaged position in which the rotor 12 is no longer capable of driving the lever 24 in rotation and in which the drive 26 ensures the locking in rotation of the lever 24 relative to the stator 14 of the lock 10.
  • the rotor 12, the stator 14 and the intermediate sleeve 16 are stationary in translation along the axis A1 relative to each other and a helical compression spring 30 is interposed between the rotor 12 and the driver 26 to urge the latter axially forward towards its engaged position.
  • stator 14 is of generally cylindrical tubular shape and it comprises means (not shown) which allow the mounting and fixing of the lock 12 on the vehicle.
  • the rotor 12 is intended to receive flakes 32 arranged in transverse planes which follow one another at regular intervals in the direction of the axis A1 of the latch 10 and which are received in corresponding housings 34 of the rotor 12.
  • the flakes 32 are movable radially in the rotor 12 and they are elastically urged towards a projecting position in which they partially protrude outside the housings 34 of the rotor 12.
  • the flakes 34 are not entirely retracted and are received inside a corresponding window 36 arranged in the intermediate sleeve 16.
  • the flakes 34 immobilize the rotor 12 in rotation relative to the intermediate sleeve 16 which itself remains free to rotate relative to the stator 14.
  • the indexer 28 is shown more particularly in FIG. 5.
  • the indexer notably comprises a main ring 38 and guide tabs 40 which extend axially rearward from the ring 38 and which are intended to be received in corresponding axial notches 42 of the intermediate bush 16.
  • the notches 42 open axially forwards into the front axial end 44 of the sleeve 16 so that, with the guide tabs 40, they make it possible to ensure the connection in permanent rotation of the indexer 28 with the intermediate sleeve 16, while leaving the possibility for the indexer 28 to move axially in the latch 10.
  • the guide tabs 40 are protruding radially with respect to the ring 38 so that the ring 38 can be received inside the axial end 44 of the socket 16.
  • the guide tabs 40 are four in number and are angularly distributed at 90 ° relative to each other on the ring 38.
  • the indexer 28 also comprises two lugs 46 which extend axially forward in the extension of two guide lugs 40 diametrically opposite.
  • the lugs 46 have, in section through a plane tangential to the ring 38, a substantially trapezoidal shape, symmetrical with respect to the axial direction, the small base of the trapezium forming a transverse front edge 48 and the large base of the trapezoid forming two surfaces transverse 50 arranged on either side of the longitudinal faces of the corresponding guide tab 40.
  • the lug 46 and the corresponding tab 40 thus have substantially the shape of an arrow facing forward in the axial direction.
  • the pins 46 are intended to cooperate with the stator 14.
  • the stator 14 comprises, at its front axial end 52, an internal radial collar 54 whose rear transverse face is stepped so as to form two concentric annular faces 58 , 60 of which the first, peripheral 58, is arranged axially behind the second, internal 60.
  • the radial collar 54 is provided with orifices 62 of complementary shape to the lugs 46 of the indexer 38 so that the two faces 64 which angularly delimit an orifice 62 in the radial collar 54 form two inclined ramps so that the housing 62 is open towards the rear.
  • the indexer 28 is capable of occupying two axial positions in the stator.
  • the first known as the rest position, corresponds to that in which the lugs 46 bear axially forwards in the corresponding orifices 62 of the stator 14.
  • the indexer 28 is pivoted around its axis A1 in the stator 14, the lugs 46 are driven out of their orifice due to the inclination of the ramps 64 which delimit the housings 62 , and the indexer 28 is then found in the axially retracted rearward position in the stator 14, for example in support by the front face 48 of the lugs 46 against the peripheral annular face 58 of the radial collar 54.
  • the indexer 28 is linked in rotation to the intermediate stator 16.
  • the indexer 28 controls the translational movements of the driver 26 so as to move the latter from a forward engaged axial position to a disengaged rear axial position.
  • the driver 26, which is shown more particularly in FIGS. 6 and 7, essentially comprises two successive coaxial tubular sections, rear 66 and front 68, the rear section 66 being of larger diameter than the front section 68.
  • the rear section 66 has, at its rear axial end, an external radial collar 70 whose external diameter is substantially equal to that of the ring 38 of the indexer 28.
  • the external radial collar 70 is intended to cooperate with the lugs 46 of the indexer 28 in order to ensure the axial coupling of the indexer 28 on the driver 26.
  • the lugs 46 each have, at the front, an internal radial rim 72 so that the lug 46 has, in section through a radial plane of the indexer 28, an L shape.
  • the indexer 28 is intended to be mounted by engagement, in the transverse direction, of the two lugs 46 on the radial collar 70 of the driver 26, the flange 72 of each of the two lugs 46 then being in contact with an annular face front 74 of the external radial collar 70.
  • the ring 38 of the indexer 28 is then pressed axially forward between an annular rear end face 76 of the driver 26 so as to make the driver 26 and the indexer 28 axially integral with one the other.
  • the front section 68 of the driver 26 comprises, on its external cylindrical face, hollow grooves 77 which are intended to cooperate with complementary grooves 78 of the control lever 24 which, as can be seen more particularly in FIG. 4 , are formed in relief on an internal cylindrical face of a cylindrical crown 80 which extends axially rearward from a rear face 82 of the lever 24.
  • the driver 26 and the control lever 24 are intended to be always coupled in rotation by their complementary grooves 77, 78, regardless of the axial position of the driver 26 which is movable in the latch 10 while the lever 24 is axially fixed relative to the stator 14.
  • the raised grooves 78 of the lever 24 extend axially towards the rear beyond the crown 80 and the hollow grooves 77 of the driver 26 are formed so as to open axially towards the rear at inside the space delimited by the rear cylindrical section 66 of the driver 26.
  • the front cylindrical section 68 of the driver 26 comprises, at its front axial end, an internal radial collar 84.
  • the driver 26 is intended to be mounted at the front of the rotor 12 which essentially comprises a central section 86, in which the housings 34 of the flakes 32 are arranged, and which is extended axially towards the front by an intermediate section 88 and by an end section 90 which are of decreasing diameters.
  • the front end section 90 of the rotor 12 comprises four drive notches 92 which extend radially outwards, being arranged at 90 ° relative to each other, and which are intended to be received in corresponding cavities 94 formed in the radial collar 84 of the driver 26 when the latter is in the engaged position.
  • the cavities 94 of the driver 26 open radially inwards and axially forwards and towards the back.
  • the diameter of the opening delimited by the internal radial collar 84 of the driver 26 is substantially equivalent to the external diameter of the end section 90 of the rotor 12.
  • the notches 92 of the rotor 12 are arranged axially at a sufficient distance from the rear end of the end section 90, delimited by the front end of the intermediate section 88, to allow the driver 26 to move back to its disengaged position in which the notches 92 of the rotor 12 are released from the cavities 94 of the coach 26.
  • the internal diameter of the front tubular section 68 of the driver 26 is substantially equal to the external diameter of the intermediate section 88 of the rotor 12 so that the intermediate section 88 can be received inside the front section 68 of the driver 26 when the latter is in the disengaged retracted position.
  • the internal diameter of the rear tubular section 66 of the driver 26 is greater than that of the front section 68 and therefore greater than the external diameter of the intermediate section 88 of the rotor 12 so as to delimit radially between the intermediate section 88 and the section rear 66 of the indexer 26 an annular space in which is housed the compression spring 30 which biases the driver 26 and the indexer 28 axially forward.
  • the spring 30 bears axially forwards against an annular face 96 of the coach 26 which is turned towards the rear and which forms the recess between the front 66 and rear 68 sections of the coach 26.
  • the spring 30 is also axially rearwardly supported against a transverse annular face 98, turned towards the front, delimited between the central 86 and intermediate 88 sections of the rotor 12.
  • This transverse face 98 of the rotor 12 is also notched on its external radial periphery so as to delimit four axial fingers 100 which are arranged at 90 ° from one another and which are intended to be received in corresponding notches 102 which are formed in a rear transverse face 104 of the ring 38 of the indexer 28 when the indexer 28 is in the retracted disengaged position.
  • the notches 102 are arranged in correspondence with each of the guide tabs 40 of the indexer 28.
  • the indexer 28 when, following the introduction of a non-conforming key into the rotor 12, the indexer 28 is in the withdrawn disengaged position, it is immobilized in rotation relative to the rotor 12.
  • the driver 26 also comprises pins 106 which extend radially outwards from an external cylindrical surface of the rear section 66 of the driver 26.
  • the pins 106 are intended to be received, when the driver 26 is in retracted position disengaged, inside a corresponding housing 108 formed in the front transverse face 110 of the radial collar 54 of the stator 14.
  • the driver 26 is then locked in rotation relative to the stator 14.
  • the housings 108 of the stator 14 extend angularly in an arc greater than the angular arc corresponding to the transverse dimension of the pins 106. In fact, this is made necessary because, when the driver 26 is moved back to its disengaged position by the indexer 28, it continues to be rotated by the rotor 12, as long as it has not reached its disengaged position. Thus, the coach 26 is driven in a substantially helical movement.
  • FIG. 8 shows the latch 10 when the indexer 28 and the driver 26 are in the advanced position engaged so as to allow, using a conforming key, to control the rotation of the lever 24.
  • the lugs 46 of the indexer 28 are then received at the bottom of the orifices 62 of the stator 14 so that the spring 30 biases the whole of the indexer 28 and the driver 26 forwards.
  • the flakes 32 are retracted inside the rotor 12 and the intermediate sleeve 16 is free to rotate relative to the rotor 12 and it is immobilized relative to the stator 14 due to the fact the engagement of the lugs 46 in the housings 62.
  • the driver 26 is in the advanced clutch position so that, in addition to being integral in rotation with the lever 24 by the complementary grooves 77, 78, it is also coupled in rotation with the rotor 12 due to the engagement of the notches 92 of the rotor 12 in the corresponding cavities 94 of the driver 26.
  • the rotor 12 is able to rotate the lever 24 to control the locking or unlocking of the lock mechanism.
  • the flakes 32 then keep the intermediate bush 16 integral in rotation with the rotor 12 so that an attempt to rotate the rotor 12 causes a relative rotation of the bush 16 by relative to the stator 14, rotation allowed by the fact that the indexer 28 moves back to its disengaged position by the cooperation of the lugs 46 with the ramps 64 delimiting the orifices 62 of the stator 14.
  • the indexer 28 moving back to its disengaged position, drives with it the driver 26 in the disengaged position as shown in FIG. 9.
  • the notches 92 of the rotor 12 are released from the cavities 94 of the driver 26 and the pins 106 of the driver 26 are engaged in the housings 108 of the stator 14.
  • the driver 26 is thus immobilized in rotation and it blocks the lever 24 in rotation thanks to the complementary grooves 77, 78 which remain engaged despite the relative axial displacement of the driver 26 relative to the lever 24.
  • the rotor 12 is no longer linked in rotation with the driver 26 and thus finds itself completely free in rotation. The rotor 12 is thus disengaged from the rest of the lock mechanism and can no longer act on it.
  • FIG. 10 shows an intermediate position of the driver 26 and of the indexer 28, between their engaged and disengaged positions. This position is likely to occur after the bolt has been disengaged and therefore the indexer 28 and the driver 26 are then initially in the retracted position shown in FIG. 9.
  • the lugs 46 of the indexer 28 are therefore likely to be found opposite the corresponding orifices 62 of the stator 14. Then, under the action of the spring 30, the indexer 28 and the driver 26 are moved forward towards their engaged position.
  • Adequate axial positioning of the different elements of the latch 10 then makes it possible, on the one hand, to prevent complete re-engagement of the mechanism if the rotor 12 is actuated using a non-conforming key, and on the other hand, 'assurance of an automatic clutch of the mechanism requiring less than a quarter of a rotation of the rotor 12, in the presence of a conforming key.
  • a mechanism is chosen in which the total travel of the indexer 28 of the driver 26 between their engaged position and their disengaged position is slightly greater than 3 mm. It is then expected that, in the engaged position, the notches 92 of the rotor 12 are received in the cavities 94 of the driver 26 only over an axial distance of the order of 2 mm.
  • the indexer 28 when the indexer 28 is in the disengaged position, it is chosen that the axial fingers 100 of the rotor 12 and the notches 102 of the indexer 28 cooperate only over an axial length of the order of 1 mm.
  • the axial fingers 100 of the rotor 12 are then released from the notches 102 of the indexer, but the pins 106 of the driver remain blocked inside the housings 108.
  • the intermediate dornille 16 remains integral with the rotor 12 due to the presence of the flakes 32 and any further rotation movement of the rotor 12 results in a new complete disengagement of the mechanism .
  • the indexer 28 and the driver 26 do not return to the fully engaged position if the key is not in conformity, which makes it possible to prevent the lever 24 from being released relative to the stator 14.
  • the key introduced into the rotor 12 is a conforming key
  • the rotor 12 and the intermediate sleeve 16 are found free relative to one another in rotation but the driver 26 remains locked in rotation relative to the stator 14. It follows that it is then possible to continue the rotational movement of the rotor 12 while keeping the driver 26 perfectly still so that the notches 92 of the rotor 12 will move relative to the radial collar 84 of the coach 26 until it finds itself opposite the cavities 94. Providing four notches 92 distributed at 90 °, and as many cavities 94, this situation occurs every quarter of a turn.
  • the driver 26 can advance to its engaged position and the rotor 12 can then control the rotation of the control lever 24.
  • the lock 10 which has just been described therefore makes it possible to produce a releasable high security lock while using components which can be obtained in a simple manner by molding.
  • the forces transmitted by the various components are such that the risks of deterioration of the parts involved are minimized.
  • the assembly of such a lock proves to be very easily automated.
