Definitions

  • the present invention relates to a lock for a vehicle in particular for a hood of the type comprising a movable part or bolt secured to said hood in an opening or closing movement thereof and a fixed or keeper part secured to an element of the body of vehicle, the bolt being constituted by a fork rotating about an axis secured to a support element fixed to said hood and comprising lateral slopes for entry into a strike box integrally carrying a nail disposed perpendicularly to the plane of the support element fork and able to be overlapped, during a translational movement, by a longitudinal notch of said fork support element in a direction of insertion, until the latter swivels in rotation to become integral with said keeper nail by hanging.
  • this type of lock is also intended for closing a vehicle tailgate.
  • French patent application No. 2 633 654 proposes to remedy this drawback by arranging in the strike housing a pair of wedge-shaped pads capable of sliding longitudinally against springs, by a push of the fork-holder element forming a bolt, when the hood is closed.
  • This device is not only complex and expensive because it requires the implementation of several parts to be assembled together, but moreover if there is a lateral offset between the bolt and the striker, this will result in a more or less pronounced depression.
  • one of the two sliding corners thus creating an asymmetry of lateral holding; in fact, this holding is directly linked to the spring pressure force exerted on each of the corners and to the angle of the contact surface between the latter and the fork-carrying element.
  • the object of the present invention is to remedy these drawbacks and to this end relates to a lock for a vehicle, in particular for a hood of the type comprising a movable part or bolt secured to said hood in an opening or closing movement of the latter and a part fixed or keeper secured to an element of the vehicle body, the bolt being constituted by a fork rotating about an axis secured to a support member fixed to said cover and comprising lateral entry slopes in a keeper case bearing integrally a nail arranged perpendicular to the plane of the fork support element and capable of being overlapped during a translational movement, by a longitudinal notch of said fork support element in a direction of insertion, until the latter swings in rotation in order to join said keeper nail by hooking, characterized in that the keeper housing comprises means of self-centering with respect to the fork support element when 'an initial adjustment or compensation for the possible eccentricity of these two elements between them during use. According to another characteristic of the invention, these means are constituted by fixed buffers
  • the lock 1 designated as a whole and shown in the figures, comprises a support element 2 fixed to the tailgate of the rear hood of a vehicle not shown, by means of a stirrup 3, from the middle of which extends in a cantilever downward said support element 2 on which is arranged a bolt constituted, in this type of lock, by a rotating fork 4 capable of turning in operation on an axis 0 secured to the support element 2 of the fork 4.
  • the support element 2 has lateral slopes 2a, 2b facilitating its introduction in a housing 5 of a keeper 6 integrally carrying a nail 7 disposed perpendicularly to the plane of the support element 2 of fork 4 and capable of being overlapped, during a translational movement, by a longitudinal notch 8 of said support element 2 in a direction of insertion, until the fork 4, carried by the element 2, rocks in rotation about the axis 0 to join said nail 7 of striker 6 by hooking.
  • the keeper box 5 is mounted integrally on the vehicle body (not shown), on the edge of a luggage compartment for example, on which the hood abuts when it is closed.
  • the keeper box 5 is secured to a fixing plate 9 comprising three slots 10 crossed during assembly by screws (not shown) capable of being screwed into corresponding threaded holes (not shown) of an inner rear wall of the trunk of the vehicle.
  • the keeper box 5 6 is defined by a parallelepiped volume open at its upper part to allow the introduction of the support element 2 of fork 4 and whose rectangular section is delimited by two lateral flanks 5a, 5b and two end walls 5c, 5d.
  • the lateral flanks 5a, 5b are crossed perpendicularly by the nail 7 fixed in overhang on the fixing plate 9 of the housing 5.
  • the strike box 6 comprises means of self-centering with respect to the support element 2 of the fork 4 during an initial adjustment or compensation for the possible eccentricity of these two elements 2, 6 between them in use.
  • These means consist of fixed buffers 11, 12 arranged opposite each other respectively on each of the opposite end walls 5c, 5d of the housing 5. These buffers 11, 12 are identical and are obtained during an operation unique plastic molding.
  • Each of the buffers 11, 12 is constituted, in the present embodiment, by a hollow element substantially forming a U whose free ends of the branches 11a 11b, 12a 12b are directed in a direction opposite to that of introduction of the element support 2 of fork 4, the branches 11b and 12b facing the axis XX ′ of the lock 1 being elastically deformable relative to the others, respectively 11a, 12a fixed on the internal end walls 5c and 5d of the housing 5.
  • Such elastic stops 11, 12 could be sufficient for them to fulfill their role as mentioned above, but in order to reinforce their elastic quality and their reliability over time, the branches 11a, 11b and 12a, 12b of each stopper 11, 12 are combined two by two near their free end by cylindrical rubber elements added respectively 13, 14, acting freely and held in place by elastic clamping between each pair of branches 11a, 11b or 12a, 12b in housing parts 13a, 14a formed respectively at said ends of the branches 11a, 11b or 12a, 12b and forming part of a cylinder , corresponding to the rubber elements to be clamped.
  • Each of the buffers 11 or 12 comprises removable fixing means cooperating with the internal end walls 5c, 5d of the keeper box 5 and which are constituted by a lug 15 or 16 provided with a head 17 or 18 and produced at the lower part of each fixed branch 11a or 12a of each stopper 11, 12.
  • An anchoring spoiler 19 or 20 is also produced at the upper part of said fixed branch 11a or 12a.
  • each stopper 11 or 12 is carried out by introducing said lug 15 or 16 is by its head 17 or 18 to the enlarged upper part of a buttonhole-shaped opening 21 or 22 formed in the internal end lateral wall 5c or 5d of the keeper box 5 5, then brought to its lower part by sliding the head 17 or 18 behind a narrowed part of said buttonhole 21, 22 until the spoiler 19 or 20 snaps elastically at the upper part of the light 21 or 22.
  • corresponding inclined inlet slopes 23, 24 are respectively provided at the free ends of the deformable branches 11b, 12b elastically of each stopper 11, 12, turned towards the axis XX ′ of the lock.
  • Each of the slopes 23, 24 is extended by faces 25, 26 parallel to said axis XX ′ of the lock 1.
  • the slopes 2a, 2b of the support element 2 are capable of cooperating with the slopes 23, 24 of the stops 11, 12 when the cover is closed.
  • the keeper 6 and the rotating fork assembly 4 disposed on its support 2 are mounted separately respectively on the edge of the trunk of the vehicle and on the hood along approximately the same axis XX ′, so as to subsequently allow a trajectory of the support element 2, substantially parallel to its notch 8 to ensure its progressive insertion into the housing 5 of strike plate 6.
  • said housing 6 is held in position by screws (not shown) passing through the slots 10, oblong in the transverse direction, but these screws are not permanently tightened in order to allow adjustment in translation of the housing 5.
  • the lights 10 allow a lateral movement thereof, of the order of 10 mm for example, caused precisely by the reciprocal contacting of the slopes 2a of the support element 2 of the fork 4 and the slopes 23, 24 of each elastic stopper 11, 12, ensuring in this way self-centering of said keeper box 5 relative to said support element 2, after which the screws are definitively blocked to immobilize the keeper 6.
  • the hardness of the rubber cylinders 13, 14 is 80 SH and the admissible crushing value is of the order of 1 millimeter.
  • a compression of 0.3 to 0.8 mm ensures excellent rigidity.
  • the slopes 2a, 2b of the support element 2 of the fork 4 form an angle ⁇ 1 of 27 ° 30 with the axis XX ′ and the entry slopes 23, 24 of the stops 11, 12 of the strike 6 form an angle ⁇ of 30 ° with the same axis.
  • the draft thus formed of 2 ° 30 facilitates the coming into contact of the elements present.
