Definitions

  • the invention relates to a filter keeper, intended to be mounted on the bodywork or on an opening of a motor vehicle to cooperate with a bolt mounted on the opposite element, opening or body.
  • Motor vehicle bodies are subject to vibrations caused not only, when driving, by the bumps on the pavement not always perfectly uniform but also, as soon as the engine works, by vibrations coming from the engine and propagating through the structure of the vehicle including through parts metal of it. This is particularly the case with motors Diesel. These vibrations, which are mostly low frequency, occur then have repercussions on door locks and can cause extremely disturbing noises for the occupants of the vehicle and even damage to the lock.
  • locks have been designed whose keeper is connected to the bodywork, or to the opening via a rubber or synthetic pad that absorbs the most much of these vibrations.
  • the strikes mounted according to this principle are fixed to a support generally comprising two superimposed metal plates and each glued to one side of said flexible material pad absorbent.
  • One of the plates, the insert intended to be secured to a element of the vehicle structure, is fixed to it by screwing in two points, while the other plate, carrying the keeper, has no other mechanical connection with this element as the rubber pad.
  • such a striker according to the prior art is mounted on a sheet 9 of the door structure, standing or opening, using two screws 4 tightening the plate lower 2 against the structural element, the head 11 of the screws being inserted through a hole 6 passing through the upper plate 3, which carries the strike 7, and a hole 5 through the bearing 1.
  • the threaded rod 12 of the screws 4 is screwed into a nut 14, located on the other side of the sheet 9 on which the keeper is mounted.
  • the hole 8 in the bottom plate 2 is oversized with respect to the cross section of the threaded rod, so that compensate for manufacturing tolerances when setting up the spoils. Only one assembly point has been shown. The other point assembly, not shown, is located on the support, symmetrically compared to strike 7.
  • This system is satisfactory from the point of view of absorption of vibrations because it saves 8 to 10 dB on noise, but it has the disadvantage that the bonding of the plates by pad does not withstand very heavy loads, as it can for example in the event of an accident, and the striker can in this case be ripped off, which causes the door to open and can cause the passenger to eject.
  • the support of the striker symmetrically with respect to the striker and on both sides a fixing screw, pins riveted to the bottom plate, passing similarly in holes in the top plate and bearing, but having a head whose diameter is greater than that of the hole in the top plate and extending above the top plate. So when the solicitation of the link of the bearing with the plates exceeds the tearing resistance of the latter, the upper plate carrying the keeper is detached from the bearing and abuts on the heads of the pawns, which prevent the separation of the spoiler and structure.
  • the lifting effort in the event of an accident can be such that strike plate top plate flexes in center between the two pawns, which are distant from each other.
  • the tensile force on the head of the pieces is applied at an angle and can lead to its deformation then to its passage through the hole.
  • a transverse force can be exerted, which causes a shearing of the rod of the two pawns.
  • the object of the invention is therefore to solve these problems in order to improve the security of the strike attachment as well as the time of mounting it.
  • a keeper is mounted on a support made at by means of two superimposed plates, the lower plate, the insert, is intended to be secured to said sheet and the upper plate carries the keeper, the two plates being joined to each other by gluing, or any known means, on both sides of a filter material pad vibrations, in particular rubber or flexible synthetic material, sandwiched between the two plates, the keeper support being provided with at least one screw passage hole, the diameter of the hole in the top plate and the hole in the bearing being higher than that hole in the bottom plate, the bottom plate being attached to the sheet metal by means of at least one screw, the head of which has a section transverse higher than that of the hole in the lower plate and lower than that of the hole in the upper plate, characterized by the fact at least one screw has a double head, the first head being intended to come to rest on the lower plate and to tighten it on the sheet for fixing the strike, while
  • the second head of the screw has a diameter greater than that of the hole in the plate upper, to serve as a safety plate retainer higher than the lower plate in case of longitudinal force exerted on said striker, that is to say an effort substantially perpendicular to the plane of the support.
  • the first head is in one piece with the rest of the opinion. It consists of a washer threaded or screwed onto the rod screw thread and tightened against the bottom plate via of the second head.
  • the hole of passage of the screw in the lower plate has a diameter between that of the threaded rod of the screw and that of the first head so as to allow adjustment of the strike position relative to the bolt associated which is mounted on the other element opposite the vehicle automobile.
  • the edge of the hole passage of the screw in the upper plate is covered with a elastic annular packing, for example of rubber or the like, having an elastic lip towards the inside of the hole, so as to make the diameter of the hole smaller than that of the first head, to allow the first head of the screw to be put in place by deformation elastic of the lip during the passage of the head and to retain the screw on the support, before fixing.
  • a elastic annular packing for example of rubber or the like
  • the lining annular and the lip are obtained by overmolding of the plate upper and form a single body with the pad.
  • the support is fixed on the sheet by tightening the threaded rod of the screws in nuts prisoners in a cage or welded to the side of the sheet opposite the spoils.
  • the security of the fixation is reinforced by at least one counter, crossing with play peripheral the upper plate by a hole, the rod of each pawn being secured to the bottom plate by screwing or riveting and the head of each pawn being spaced and located above the plate upper after its installation, said head having a diameter higher than that of the pawn passage hole in the upper plate in order to retain it in the event of a break in the connection with the bearing.
  • FIG. 2 shows one of the two fixing points according to the invention of a motor vehicle door strike.
  • the keeper support consists of two plates 2 and 3 joined by gluing or any known means to a pad 1 rubber or flexible synthetic material sandwiched between the two plates.
  • plates 2 and 3 of the support keeper as well as the bearing 1 are provided with a through hole for a screw 4 intended for fixing the lower plate 2 to the structure.
  • the screw 4 has a double head, the heads 10 and 11 of which have substantially the same diameter, slightly less than the diameter of hole 6 of the upper plate 3 carrying the keeper proper (not shown). Between the head 10 and the head 11, the screw 4 has a middle part 4a diameter less than that of the heads and greater than that of the rod threaded 12.
  • She also passes through the structural element 9 through a hole 13 (opening or of the frame) and is screwed into a nut 14 trapped in a cage 21 (visible in Figure 1) or welded at 22 to sheet 9 on the side opposite the spoils.
  • the cage 21 rotates the nut to the sheet metal 9.
  • the head 10 has on its top a housing 4b of hexagonal shape for its cooperation with a screwdriver of complementary shape.
  • pins 15 shown in the figure 5 The safety of the connection of the strike plate to sheet 9 is ensured, in the event tearing of the pad 1, by pins 15 shown in the figure 5.
  • These pins are screwed or riveted or welded to the bottom plate 2 and their rod 17a crosses the upper plate 3 through a hole 16, the diameter is less than that of the head 17b of the pin, said rod 17a also passing through pad 1 to attach to the plate lower 2.
  • the rod 17a of each pin 15 is spaced from hole 16 by a peripheral clearance j of the order of 0.4 mm and the head 17b is spaced from the top of the plate 3 by a height h of the order of 1 mm.
  • the pad 1 is capable of absorb deformations whose elongation x is between - 0.4 and 0.4 mm, while retaining its elasticity. During these deformations, the pins do not come into contact with the plate superior 3. Beyond 0.4 mm deformation, the material of the bearing can undergo plastic deformations, even tear, take off or break, as indicated by the steep slope on the graph illustrating the relationship between the intensity of the transverse force of shear F exerted on the support and the elongation of the bearing under this effort.
  • the keeper thus fixed on the structure can be guaranteed, not only, against separation of the structure in the event of impact causing the connection with the bearing 1 to be torn off in the direction longitudinal but also against a shear failure of the safety pad by improving the shear strength in case of of transverse stress.
  • the heads 110 of the screws 4 have a diameter greater than that of the hole 6 of the upper plate 2. Thanks to this measurement, the head 110 of the screws plays the same role as the head 17b of the pawns 15 of FIG. 5 (on which the pad 1 has been omitted to facilitate understanding of the drawing). These the latter can therefore be deleted since the screws 4 ensure that the both the pullout resistance and the shear strength.
  • the second head of the screw 4 consists of a washer 111 of same diameter as the above-mentioned head 11 and is threaded or screwed onto the rod 12 under a shoulder of the middle part 4a of the screw.
  • the washer 111 plays the same role as the head 11 when the screw 4 is tightened, the middle part 4a pressing the washer 111 against the lower plate 2.
  • the washer 111 is located at a portion 12a of smaller section at the base of the threaded rod 12.
  • the edge of the holes 6 in the upper plate 3 is provided with an annular lining 18 in rubber or flexible synthetic material, overlapping the faces upper and lower plate around hole 6.
  • This trim has an annular lip 19 projecting radially towards inside the hole.
  • the keeper can be brought to the mounting location on the vehicle with its screws fixing, without the fitter having to provide a supply of separate screw, where he must take the screws that he inserts into the holes of passage before tightening them. This reduces the assembly time. In addition, there is no risk of losing the screws during assembly, as they cannot fall out of the holder.
  • the keeper 7 is formed a plate provided with an opening 7a into which can be inserted a branch of a fork bolt of a lock case known per se.
  • the pad 1 does not extend vertically from the the top plate.
  • the lining 18 preferably comes from molding with the pad 1, it can be provided that said lining is a separate part pad 1 (which can also be in several parts).
