Definitions

  • the present invention relates to a lock of the disengageable rotor type.
  • the invention relates more particularly to a lock intended to be used for controlling a lock mechanism fitted to a motor vehicle allowing, for example, the locking of an opening leaf of the vehicle such as a door.
  • the main ones consist in acting on the lock, in particular by means of a false key.
  • a disengageable rotor lock are of the type comprising a rotor mounted journalling in an intermediate stator in the form of a bushing itself pivotally mounted in a fixed lock 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 angular indexing member of the stator intermediate with respect to the fixed body which is mounted movable between an indexing position in which it is resiliently recalled and in which it is received in a notch of the fixed body, and a position retracted in which it is erased, against an elastic return force.
  • the indexing member is for example in the form of an arm arranged in a longitudinal housing formed in the peripheral wall of the intermediate stator, the arm comprising on its external radial face a projection which, in the indexing position, is received radially in a longitudinal groove formed in the internal wall of the fixed lock body so as to make the intermediate stator integral in rotation with the fixed body, in the absence of a key or in the presence of a conforming key .
  • a disengageable mechanism for controlling a lock has also been proposed, fitted in particular to a motor vehicle opening, of the type comprising a disengageable rotor lock as described in document FR-A-2,642,463.
  • the object of the present invention is to propose a new design of a disengageable rotor lock of the type mentioned above, which overcomes the drawbacks which have just been mentioned.
  • the invention proposes a lock, the indexing member being eccentric and mounted to move axially between its indexing and retracted positions, the lock comprising an outlet member mounted to rotate relative to the fixed body of the lock and which is linked in rotation to the rotor by disengageable drive means, the disengagement of which is caused by the indexing member of the intermediate stator when it is in the retracted position, characterized in that the member of angular indexing immobilizes the output member in rotation relative to the fixed lock body when it is in the retracted position.
  • the lock 10 illustrated in the figures essentially consists of a main lock body 12 forming a fixed stator intended for example to be mounted in a lock housing or directly in a housing of a vehicle door, an intermediate stator 14 , a rotor 16 and by an output member 18 intended to be connected to a lock control mechanism (not shown).
  • the lock body 12 essentially consists of an external cylindrical annular jacket 20 open at its rear axial end 22, by convention on the right when considering the figures, and closed at its axial end front by a radial flank in the form of an annular disc delimiting a bottom 24 pierced in its center by a circular hole 26.
  • the bottom 24 has a notch 28 which opens axially on either side of the transverse bottom 24 and which is open radially towards inside in hole 26.
  • the notch 28 is a notch with parallel radial edges capable of receiving in axial sliding an indexing member constituted by a spherical ball 30.
  • the intermediate stator 14 is in the general form of a cylindrical sleeve 32, the convex external cylindrical surface 34 of which is intended to be received in rotation in the concave internal cylindrical wall 36 of the sleeve 20 forming a fixed lock body 12.
  • the tubular cylindrical sleeve 32 is axially delimited by an annular rear end face 38 and by an annular transverse front end surface 40 which, in the assembled position of the components, is in axial abutment against the front transverse bottom 24 of the lock body 12.
  • the annular transverse surface 40 comprises an indexing notch 42 produced in the form of a substantially inverted V-shaped cam profile which extends axially towards the rear and which is capable of at least partially receiving the ball of indexing 30.
  • the tubular sleeve 34 of the intermediate stator 14 is extended axially forwards beyond the annular transverse track 40 by a front end section 44 the diameter of which is such that it rotates through the hole 26 in the front transverse bottom 24 of the lock body 12.
  • An inner radial groove 46 is formed in the peripheral cylindrical surface 48 of the end section 44, substantially halfway along the latter.
  • An axial groove 50 is also formed in the cylindrical surface 48 and it extends axially from the annular end face 52 of the section 44 to the radial groove 46 into which it opens.
  • the axial groove 50 is angularly aligned with the indexing notch forming a cam 42.
  • the sleeve 34 internally delimits a large diameter bore 54 (FIGS. 3 and 4) open axially towards the rear to receive the rear main body 56 of the rotor 16 and it is extended forward by a reduced diameter bore 58 formed at through the front end section 44 intended to receive a front end tail 60 of the rotor 16.
  • the body 56 of the rotor 16 is a barrel in which flakes 59 are mounted which are received radially in housings 62 in which they can be retracted radially inwards, in the presence of a conforming key.
  • the assembly of the body 56 and of the flakes 59 is mounted axially and in rotation in the tubular sleeve 34 of the intermediate stator 14 and in the mounted position, the annular face 64 of the rotor 16 is in axial support against the annular faces of the rear end 22 and 38 of the lock body 12 and of the intermediate stator 14.
  • the axial length of the front end tail 60 is substantially equal to the length of the front extension 44 and it projects beyond the latter by a section of rectangular section 66.
  • the output member 18 of the lock which is also called the thresher of the lock mechanism with which the lock is associated, is constituted by a generally plate-shaped element comprising a central portion 68 in the form of an annular disc which extends radially towards the outside by a transverse arm 70.
  • the disc-shaped central part 68 is pierced at its center by a circular hole 72 of the same diameter as the hole 26 in the transverse bottom 24 of the lock body 12 so as to allow the axial passage and the rotation of the front end section 44 of the intermediate stator 14 which extends axially, in the mounted position, through the threshing machine 18 beyond the front face 74 of the latter while its rear face 76 is in axial abutment against the annular front end face 24 of the lock body 12.
  • the central part 68 of the thresher has a through axial slot 78 which passes right through it and which is open radially inwards in the wall of the hole 72.
  • the slot 78 is a slot with parallel edges which are spaced transversely from one another to allow the axial sliding of the indexing ball 30 inside the slot 78.
  • the axial depth of the indexing notch 42 forming a cam and the diameter of the indexing ball 30 are such that, in the indexed position of the ball 30, and as can be seen in particular in FIGS. 6 and 7, this is received in axial support in the bottom of the notch 42 and in the notch 28 but it does not extend axially forward, that is to say to the left when considering Figures 6 and 7, beyond of the annular front end face 25 of the transverse bottom 24 and it therefore does not protrude axially in the slot 78.
  • the rotor 16 is produced in two parts, the second of which consists of a front end piece 80 in the general shape of a cylindrical pot delimited by a cylindrical annular skirt 82 and by a front transverse bottom 84 pierced by a hole of rectangular section 86 complementary to the section of the end 66 of the rear main body 56 of the rotor 16 and making it possible to orient the end piece 80 angularly relative to the body 56.
  • the skirt 82 is delimited axially towards the rear by an annular rear end surface 88 which is in axial abutment against the front face 74 of the central part 68 of the threshing machine 18.
  • the skirt 82 delimits an internal cylindrical housing 90 in which the front end section 44 of the intermediate stator 14 is received in rotation.
  • the rotor end piece 80 is linked in rotation to the rear part 56, 60 of the rotor 16 and it is fixed axially by means (not shown) arranged for example in the form of an elastic ring received in the free end of the drive square 66 so that all of the components are retained axially with respect to each other in the assembled position.
  • the rotor end piece 80 has a cavity 92 of axial orientation which opens into the rear end face 88 of the skirt 82 of the end piece 80 and which is delimited axially towards the front by a bottom 94.
  • a key 100 is received by sliding at least partially inside the axial cavity 92.
  • the key 100 is here produced in the form of a slide 102 of rectangular section complementary to the cross section of the cavity 92 and which is stressed axially from front to back, that is to say from left to right considering the figures, by a helical compression spring 96 which bears against the bottom 94 of the cavity 92 and against the axial face in screws opposite the slide forming a key 102.
  • the radial thickness of the slide 102 separating its faces of lower 104 and upper axial orientation 106 is slightly less than the radial distance separating the bottom of the notch 28 and the bottom of the slot 78 (which are aligned) of the peripheral cylindrical surface 45 of the front extension 44 of the intermediate stator 14.
  • the radial thickness of the slide 102 thus corresponds substantially to the diameter of the indexing ball 30.
  • the slider 102 In its rest position illustrated in particular in Figures 3 and 6, the slider 102 is axially biased in abutment against the indexing ball 30 against which it is in axial abutment by its rear transverse face 110 which is located in the same plane as that from the rear face 76 of the thresher 18, the slider 102 being thus received simultaneously in the slot 78 and in the cavity 92 to immobilize the thresher 18 in rotation relative to the rotor 16, 80.
  • the slide 102 has, on its underside 104, a tail 114 oriented radially inwards which here extends in line with the internal radial groove 46 formed in the extension 44 of the intermediate stator 14 in which it is received radially and whose the dimension is such that it allows it to slide in the groove 46 as well as in the axial groove 50 as will be explained later.
  • the rotor 16, 56 is not linked in rotation to the intermediate stator 14, 44 and it is free to rotate relative to the latter.
  • the rotation of the rotor 16 using a conforming key therefore causes the simultaneous rotation of the end piece 80 and of the threshing machine 18 which slide in rotation between the annular faces opposite 88 and 25.
  • the intermediate stator 14, 44 is immobilized in rotation relative to the fixed latch body 12 by means of the indexing ball 30 which is received axially simultaneously in the indexing groove 42 and in the notch 28 formed in the transverse bottom 24 of the lock body 12.
  • the rotor 16, 80 therefore drives the slider 102 and the threshing machine 18 in rotation relative to the lock body 12, the tail 114 of the slider 102 being slidably received in the groove 46 formed in the front extension 44 of the intermediate stator 14.
  • the indexing ball 30 thus immobilizes directly in rotation the threshing machine 18 relative to the fixed lock body 12.
  • the ball 30 caused the slide forming the keyway 102 to slide simultaneously, from right to left, starting from FIG. 6 so that it is entirely retracted, against the return force exerted by the spring 96 in the cavity 92, its transverse rear end face 110 then being in axial abutment against the front face 74 of the central part 68 of the threshing machine 18.
  • the tail 114 of the slider 102 could penetrate into the axial groove 50 to allow the axial retraction movement of the slider forming the key 102 inside. from cavity 92.
  • the threshing machine 18 is itself immobilized in rotation relative to the lock body 12 by means of the indexing ball 30.
  • the disengageable drive means 100, 102 are therefore retracted and the only action vis-à-vis the threshing machine 18 is fulfilled by the indexing member 30.
  • the thief cannot therefore cause rotation of the threshing machine 18, beyond an initial stroke of a few degrees, and he cannot therefore actuate the lock connected to the threshing machine 18.
