Definitions

  • the invention relates to a motor vehicle lock comprising an improved glitter retaining bar.
  • Document CH 596 416 A describes a vehicle lock according to the preamble of claim 1.
  • the invention relates more particularly to a lock motor vehicle, of the type comprising a rotor mounted for rotation around its axis in a socket, of the type in which flakes are slidably mounted in the rotor, in one direction transverse, between at least one extreme projecting position in which they immobilize in rotation the rotor with respect to the sleeve, and an extreme retracted position in which they are received at inside the rotor and towards which they are forced by the introduction in the rotor of a conforming key, and of the type in which the position extreme protruding glitter is determined by a bar in plastic material which extends axially in the rotor and against which rests on a stop surface of the glitter.
  • the plastic bar allows to limit the glitter stroke in the transverse direction without the arrival of each of the flakes in contact with the bar causes the significant noise that would be produced in the event of contact metal against metal.
  • Such a bar also makes it possible to limit the risks of electrochemical corrosion which could occur at the level of a contact between two pieces of different metallic materials.
  • the object of the invention is therefore to propose a new design of the bar of such a lock which makes it possible to provide a solution to these problems.
  • the invention provides a vehicle lock automobile, of the type comprising a rotor rotatably mounted around its pin in a socket, of the type in which flakes are mounted sliding in the rotor, in a transverse direction, between the minus an extreme projecting position in which they immobilize in rotation of the rotor relative to the sleeve, and an extreme position retracted in which they are received inside the rotor and towards which they are forced by the introduction into the rotor of a key conform, and of the type in which the extreme projecting position of glitter is determined by a plastic bar which extends axially in the rotor and against which a abutment surface of the straw, characterized in that the bar is in elastic support on the flakes in a radial direction perpendicular to the transverse direction of sliding of flakes.
  • FIG. 1 shows a lock rotor 10 as well as straw 12 intended to be received in housings 14 of the rotor 10 in which the flakes 12 can slide in a transverse direction perpendicular to the axis A1 of the rotor 10.
  • the sequins are produced substantially in the form of plates 12 and they are slidably mounted between a position extreme projection which is shown in Figure 8 and a position retracted shown in Figure 9.
  • the flakes 12 are guided in their housings 14 by two external lateral edges 34 of orientation cross.
  • a socket 15 can either be the stator of a non-bolt disengageable, i.e. the intermediate stator of a disengageable lock, to which in this case the bushing is itself rotatably mounted in the stator.
  • the rotor 10 can rotate freely around its axis A1 in the socket 15.
  • the flakes 12 are brought to their retracted position using a conforming key 16 including the key rod 18 cooperates with the flakes 12 to cause them to slide at inside the accommodation 14.
  • the key rod 18 is intended to be introduced axially from back to front in a key passage 20 which extends axially to inside the rotor 10, the key rod 18 then being received inside a window 22 arranged in each of the glitter 12.
  • the rod of key 18 is of rectangular section, elongated in the direction of glitter slide.
  • the key rod 18 On each of its two opposite faces 24 which are parallel to the direction of glitter sliding, the key rod 18 comprises a cam path 26 which is hollowed out.
  • Each glitter 12 has a radial lug 28 which extends towards the inside of the window 22 from an edge 30 of the window 22 parallel to the direction transverse sliding of the straw 12. This radial lug 28 is intended to be received in cam path 26 so as to follow therefrom exactly the profile so that an axial displacement of the key 16 causes a displacement of each of the flakes 12 according to their sliding direction.
  • the cam path 26 is delimited by two parallel edges, but not straight, which make it possible to control the movements glitter 12 in both directions in the sliding direction.
  • cam tracks 26 of each of the faces 24 lead to the free front end of the key rod 18 where they have a flare intended to facilitate the entry of the pins 28 into the cam path 26 when the key 16 is introduced into the rotor 10.
  • the lock which is shown in the figures is a lock of the type without spring.
  • a lock of this type is described in the patent French No. 960.244.
  • the flakes 12 are not biased towards their projecting position by a return spring.
  • the path cam 26 in which the pins 28 are received causes displacement of each straw 12 according to its sliding direction so that, when the key rod 18 is completely removed, the flakes 12 are in their protruding position.
  • means are provided for limiting the glitter stroke 12 in their housing 14, to avoid in particular that they cannot go beyond their protruding position at the risk of escape from the housing 14.
  • each flake 12 comprises, on one of its lateral edges 34 parallel to the sliding direction, a notch 36 inside which the bar 32 is intended to be partially received.
  • the bar 32 which is fixed in the rotor 10, is capable of cooperating with transverse flanges 38 which delimit the notch 36 to limit the stroke of the straw 12, as well as this is shown in Figures 8 and 9.
  • the bar 32 is intended to be engaged in an axial housing 33 which extends parallel to the key passage 20 and which is arranged according to the radial direction so that it communicates with the housings 14 glitter 12 by partially encroaching on these housings.
  • the flakes 12 have, on the outer lateral edge 34 opposite to that which carries the notch 36, an indexing spout 37 which extends transversely outwards. So that this indexing spout 37 does not impede the sliding movement of the straw 12, the housings 14 of rotor 10 are provided with a clearance 39 corresponding to spout 37.
  • the bar 32 also has the function of making up for play, in the radial direction perpendicular to the transverse sliding direction, that it is necessary to provide to ensure proper sliding of each straw 12 in its housing 14.
  • the bar 32 has elastic arms 40, in number equal to that of the glitter 12, which are likely to come in elastically supported in the radial direction against the notch 36 of a corresponding straw 12 so that the latter is supported by its external lateral edge 34 opposite to that in which is practiced the notch 36 against a transverse lateral wall 42 of the housing 14.
  • the arms 40 are arranged axially at regular intervals along the strip 32 and each is in the form of a plate element which extends, when in the free state, substantially in an axial orientation plane slightly inclined with respect to the transverse direction of glitter sliding 12.
  • Each arm 40 is connected to a main body 44 of section rectangular of the bar 32 by a connecting section 46 which extends in the radial direction from an axial edge 48 of the main body 44, in the extension of a radially oriented lateral surface 50 of the main body 44 of the bar 32.
  • each of the arms 40 is delimited axially by two edges transverse 54.
  • each arm 40 is inclined relative to the transverse direction so that a free end 52 is located away from the main body 44, towards the center of the rotor 10, to come to bear against the notch 36 of the corresponding straw 12.
  • each arm 40 is of a thickness reduced compared to that of the arm 40 itself so that most of the deformation of the bar 32 in the direction radial is ensured by a pivoting of the arms 40 around their section link 46, the latter being elastically deformed.
  • each arm 40 When the bar 32 is in place in the rotor 10, and that the free end 52 of each of the fingers 40 is in abutment against the corresponding straw 12, arm 40 is in a constrained state in which its free end 52 is brought together, radially towards outside, of the main body 44 of the bar 32. As can be see in Figures 8 and 9, each arm 40 is not supported against the corresponding straw 12 only by its free end so as to decrease the contact surface between the two elements and thus limit friction likely to oppose the smooth sliding of the straw 12 in its housing 14 when it is ordered in movement by the compliant key 16.
  • each straw 12 with rotor 10 and with bar 32 are sufficient to the straw remains stationary when subjected to vibrations due to the running of the vehicle, this in order to avoid impact noise at lock level.
  • This also has the advantage of keeping, when the key 16 is removed from the rotor 10, the straw 12 in a position ideal in which its radial lug 28 is arranged exactly at level of the emerging end of the cam track 26 of the rod key 18.
  • each of the arms 40 are made in one single piece in the form of a continuous strip which extends along the axial edge 48 of the main body 44.
  • each of the arms 40 is independent of the other arms so that the radial clearance of each of the glitter 12 is caught individually.
  • a position extreme protrusion of the straw 12 is determined by the coming into abutment of one of the transverse recesses 38 which delimits the notch 36 against the continuous connecting strip 48 which connects the arms 40 to the body main 44 of bar 32.
  • a second extreme opposite position of the straw 12 is determined by the support coming from the other of the dropouts transverse 38 against the free end 52 of the elastic arm 40 corresponding. In this way, the transverse stroke of the straw 12 is limited and its radial lug 28 always occupies a position in which it is likely to be engaged in the flared end of the path cam 26 of the key 16. This prevents, for example following a attempt to lock the lock, the glitter 12 does not prevent the introduction of a conforming key 16 into the rotor 10.
  • the axial ends 56 of the bar 40 and the edges 54 of orientation transverse of each of the arms 4.0 are chamfered to facilitate the introduction of the bar 32 in its housing 33. Indeed, it is necessary ensure that the arms 40 do not oppose the axial introduction of the bar 32, or possibly its removal.
  • each of the arms 40 are beveled to cause deflection of the arm 40 radially outward, i.e. towards the main body 44 of the bar 32, when one of these edges 54 comes into contact, axially forwards or backwards, from the outer lateral edge 34 of a glitter 12 at its notch 36.
  • the arm 40 when the arm 40 has axially exceeded the straw 12, it is possible for it to resume its position in the free state, even if it means being deflected again by the cooperation of its edge transverse 54 with the edge of the notch 36 of the next straw.
  • the bar 32 For its axial fixing in its housing 33, the bar 32 comprises, on a lateral face 58 of its main body opposite to a transverse lateral face 60 facing which are arranged the arm 40, a lug 62 which is intended to be received in a cavity corresponding 64 fitted in a wall of the housing 33.
  • the lug 62 of substantially parallelepiped shape, extends radially towards outside and is arranged axially substantially in the center of the bar 32.
