Definitions

  • the present invention relates generally to a device for locking a lock body in its support.
  • It relates more particularly to the lock bodies intended to be mounted in a steering anti-theft casing for a motor vehicle.
  • Such bodies are generally generally cylindrical in shape and have a bore inside which is housed a lock constituted in a manner known per se of a barrel swiveling in the bore of the body, said barrel being integral with a cam bolt drive.
  • the lock and its associated cam being assembled in the body, the assembly is introduced into a support such as a steering lock box or sleeve and must be locked relative to this support.
  • this extraction must be able to be carried out only by an authorized person, that is to say by actuation of a conforming key and for an angular position different from the locking position.
  • cam for example FR-A-2 499 138
  • lock and body have been preassembled and thus form a compact unit.
  • the cam is angularly indexed relative to the lock and more precisely relative to the key channel.
  • the locking device is thereby simplified all the more since its implementation is generally carried out by an operation of the conforming key inserted into the lock.
  • the body of the lock is equipped only with the cam, without the lock, and this assembly must on the one hand be made integral with the anti-theft case, on the other hand be angularly indexed relative to said case.
  • the locking device must include a reduced number of parts so that its cost and its implementation are compatible with mass production as is the case in the automotive field.
  • the present invention solves these problems and proposes for this purpose a device for locking an anti-theft lock body in its support, said lock body being prior to its introduction into the support equipped with a control cam, the device further comprising a body locking member in the support, said locking member consisting of a generally U-shaped metal blade comprising two parallel branches connected by a curvilinear bottom, characterized in that for an angular position of the cam different from the locking position of the anti-theft device, the branches of the locking member are able to cooperate successively with radial slots in the support, radial passages in the housing and notches in the cam.
  • FIG. 1 illustrates in perspective before their assembly various components of a steering lock for a motor vehicle.
  • This anti-theft device notably comprises a body 10, a bolt control cam 12 and a support or housing 14.
  • the body 10 is of generally cylindrical shape and comprises a bore 16 intended to receive at the front an equipped lock (not shown) and at its rear part 18 the cam 12.
  • the body 10 comprises two radial passages 20, 22 (FIG. 2) symmetrical with respect to the axis X-X of the cam 12.
  • the cam 12 is in the form of a cylinder at the periphery of which two diametrically opposite radial notches 24, 26 are arranged.
  • the cam 12 is assembled to the body 10 and angularly indexed relative to the said body by means which are not part of the present invention will not be described here in more detail.
  • FIG. 2 shows the relative positions of the body 10 and of the cam 12 once assembled and before the introduction of this assembly into the housing 14.
  • the front part of the housing 14 is generally in the form of a cylindrical tube comprising a bore 28 intended to receive the body 10, cam 12 assembly.
  • This front part 14 comprises two series of radial slots 30, 30 '; 32, 32 ′ aligned horizontally as can be seen in particular in FIG. 2.
  • the slots 30.30 '; 32, 32 ′ are arranged in the body 14 at a distance h from the axis XX of the cam 12, distance h corresponding on the one hand to the bottoms of the notches 24, 26 of the cam 12, on the other hand to the faces 21 , 23 of the passages 20, 22 of the body 10.
  • the locking device also comprises a locking member consisting of a metal blade or fork 34 generally in the shape of a U comprising two parallel branches 36, 36 ′ connected by a curvilinear bottom 38 of complementary shape to the external wall 40 of the housing 14.
  • Each branch 36, 36 ′ has a width e equal to the width of the passages 20, 22 of the body 10 and comprises a circular notch 42, 42 'inscribed in a diameter D equal to the outside diameter of the cam 12.
  • branches 36,36 ' terminate in chamfered ends 44,44'.
  • the interior faces 46,46 ′ of the horizontal branches 36,36 ′ are spaced apart by a distance equal to twice the distance h.
  • the branches 36, 36 ′ of the locking fork 34 are inserted along the arrow F into the slots 30, 32 of the housing 14 and the body 10, cam 12 assembly is turned until, on the one hand, the passages 20, 22 of the body 10, on the other hand the notches 24, 26 of the cam 12 are in alignment with the slots 30, 30 '; 32.32 ′ of the housing 14 as shown in FIG. 2, so as to allow the passage of the branches 36.36 ′ of the locking fork 34.
  • the relative angular positions of the different elements body 10, cam 12 and body 14 are such that they correspond to a position different from the position for locking the anti-theft device, for example the so-called "Accessories" position of the lock key.
  • FIG. 3 illustrates a configuration of the different elements for a position different from the configuration for mounting or dismounting the fork, for example the locked position of the anti-theft device.
  • the cam 12 has pivoted anti-clockwise and its notches 24, 26 are no longer in alignment with the slots 20, 22 of the body 10, any extraction from the fork 34 is made possible. The same goes of course for any angular position of the cam 12 different from that shown in FIG. 2.
  • curvilinear notches 42, 42 ′ of the fork 34 allow the cam 12 to pivot under the action of the key, said fork 34 being in position in the body 12 and the housing 14.
