Definitions

  • This invention concerns a striker for a motor vehicle door lock.
  • door is used in this description and in the claims in its very widest sense, to indicate whatsoever moving component between an opening position and a closing position of an access aperture to an internal compartment of a vehicle.
  • the above terms consequently comprise in addition to the side doors of the motor vehicle, which will be referred to in the following without the loss of any general sense, also the hoods or front and rear doors or hatches.
  • Locks are known for motor vehicle doors essentially comprising a support body which defines an aperture communicating with the outside through a frontal aperture and provided with a metal plate able to be connected by means of screws with the motor door vehicle door, or more seldom with an upright of the door itself, a closure mechanism housed within the aperture of the support body and an actuation mechanism for the closure mechanism.
  • the closure mechanism comprises a fork hinged about a first fixed pin carried by the plate and arranged to cooperate with a striker integral with an upright of the door, or more seldom secured to the door itself, and a stop hinged about a second fixed pin carried by the plate and able to lock in a releasable manner the fork in a closure operational position on the striker itself.
  • the known locks have the following disadvantages.
  • the typical lock noises mainly due to impacts between the striker and the fork and between the latter and the stop during the door closure and phases, are propagated through the bodywork, which acts as a sounding box, and are noticeable with some disconfort both outside and inside the motor vehicle body cell.
  • the inevitable assembly clearances between each door of the motor vehicle and the relative upright generally determine a poor positioning of the lock in relation to the relative striker; in the closure mode the connection between the fork and the striker thus produces a slight elastic distortion of the door, which returns elastically to its original shape when the lock is opened, emitting an undesirable noise which is added to the aforesaid typical noises of the lock.
  • the purpose of the present invention is to achieve a lock for a motor vehicle door, which allows in a simple and economical manner the reduction of avoidable noise in the closure and the opening stages of the door of the motor vehicle itself.
  • a lock for a motor vehicle door comprising an external body having at least a first metal plate able to be secured to a portion of the bodywork of the said motor vehicle, a closure mechanism carried by the said first plate and having a fork moving between two operational positions featuring the opening and closure of the said lock respectively, and a stop able to lock in a releasable manner the fork itself in its operational closure position, and an actuation mechanism for the said closure mechanism, characterized by the fact that it comprises means of support made of relatively yielding material and able to interpose itself, in service, between the said first plate and the said bodywork portion to prevent direct metal on metal contact.
  • Fig. 1 it is indicated under reference 1 of the assembly a lock for a door 2 (Fig. 5) of a motor vehicle (not illustrated).
  • the lock 1 is of modular type and comprises a closure module 3 able to cooperate with a fixed striker (of known type and not illustrated) integral with an upright (not illustrated) of the door 2, and an actuation module 4 connected with the closure module 3.
  • the closure module 3 comprises essentially a surrounding 5 able to be secured to the door 2 and having a frontal aperture 6 for the entry of a check-dowel (not illustrated) for the striker, and a closure mechanism 7 housed within the inside of the surrounding 5 and comprising in turn a fork 8 able to cooperate with the aforesaid striker, and a stop 9 able to lock in a releasable manner the fork 7 in a closure operational position on the lock itself.
  • the actuation module 4 comprises essentially a surrounding 10 connected with the surrounding 5 of the closure module 3 and defining therewith an external body 11 of the lock 1, and a plurality of levers 12 (only visible in minimal parts in Fig. 1) housed inside the surrounding 10 and operated from the outside to actuate the closure mechanism 3.
  • the surrounding 5 comprises two plates 15, 16 located facing each other and parallel, and a bearing shell 17 interposed in a sandwich manner between plates 15, 16 themselves and internally defining an aperture 18 communicating with the outside through the opening 6 and in which is located the closure mechanism 7.
  • the plates 15, 16 are constructed of metal material, they are able to be connected to the door 2 by means of a plurality of securing means 19 also made of metal and having respective axes A located orthogonal in relation to the plates 15, 16 themselves, and supporting together the fork 8 and the stop 9.
  • the plate 15 is located in service adjacent to the door 2, whereas the plate 16 is located on the opposing part of plate 15 in relation to the door 2 itself.
  • the fork 8 is fitted to rotate about a first fixed pin 20 integral with the plates 15, 16 and extending in orthogonal manner between the plates 15, 16 inside the aperture 18 of the shell 17, whereas the stop 9 is fitted to rotate on a second fixed pin 21 also integral with plates 15, 16 and extending in orthogonal manner between the plates 15, 16 inside the aperture 18.
  • the fork 8 has a U-shaped seat (22) arranged to engage the striker check dowel, and normally retained by a spring, of a known type and not illustrated, in an opening operational position, in which the seat 22 is essentially arranged to correspond with the aperture 6 of the surrounding 5 and is turned towards the outside; in addition, in order to cooperate with the striker, the fork 8 is movable from the opening operational position to the closure operational position, in which it engages with the striker check dowel, and is arranged with the seat 22 directed towards the inside of the aperture 18 (Figs. 1, 3 and 4).
  • the shell 17 is made of relatively yielding material integrally comprising for each securing component 19, a first bearing component 23 interposed between the plate and the above securing means 19 and arranged to be interposed in service, between the plate 15 and the door 2, and a second bearing component 24 interposed between the plate 16 and the above securing component 19, to prevent direct metal on metal contacts.
  • relatively yielding material is used to indicate a relatively soft plastic material, for instance polyurethane resin, or an elastically yielding material for instance an elastomer material, and more generally, to indicate whatsoever material having a level of deformability considerably greater than that of the metal materials used for the door 2 and the plates 15, 16.
  • each securing component 19 comprises a metal bush 25 along axis A engaging coaxially with relative passing holes 26, 27 through the plates 15, 16 by means of the interposition of the respective bearing components 23, 24, having a surface 28 which is internally radially threaded to match an end section 29 adjacent to plate 16, and able to engage in service with a screw 30 inserted through a relative passing hole 31 in the door 2 and connecting the plates 15, 16 to the door 2 itself.
  • each bush 25 is fitted in a relative seating 32 on axis A recessed in the shell 17 and defined to match the opposing axial ends of the respective bearing components 23, 24, which as previously stated define integral portions of the shell 17 itself.
  • Each bearing component 23 is of annular shape along axis A and comprises a first section 33a interposed between the relative bush 25 and a lateral surface of the relative hole 26 of plate 15 and a second section 33b which in service projects axially towards the door 2 in relation to the bush 25 itself and to the plate 15 and arranged to meet the end of the relative hole 31 in door 2.
  • Each bush 25 comprises a main part 34 engaging in the respective holes 26, 27 of the plates 15, 16 and an end head 35, essentially of oblong form, having a maximum length greater than the external diameter of the portion 34 and placed to bear against the plate 16 by interposing the relevant bearing component 24. More precisely, the head 35 of each bush 25 is defined by two flat surfaces 36 parallel to each other, essentially tangential to the external surface of portion 34, and by two curved surfaces 37 convex towards the outside, facing away from each other, extending between opposing ends of the surfaces 36 and defining in association with their own central positions the maximum length of the head 35 (Fig. 6).
  • Each bearing component 24 comprises a cylindrical annular portion 38 interposed between the portion 34 of the relative bush 25 and a lateral surface of the relative hole 27 of plate 16, and a recessed portion 39 housing the head 35 of the bush 25 and having a drilled bottom wall 40 engaging with the portion 34 of bush 25 and interposed between the head 35 and the plate 16.
  • the portions 39 are achieved by integral pressing of the shell 17 in the manufacturing position, in which they protrude externally from the shell 17 and are connected thereto by means of relative strips 41, which can be folded back from the manufacturing position into the service position, in which they house the heads 35 of the respective bushes 25.
  • the shell 17 fulfils a containment function for the closure mechanism; the shell 17 can thus be advantageously manufactured from relatively yielding material, also allowing by means of the bearing components 23, 24 to achieve the important function of preventing direct metal contacts between the plates 15, 16 and the door 2 and between the latter and the securing components 19.
  • the lock 1 as an assembly is thus "isolated" from the door 2 thus allowing a considerable reduction in the propagation of noises from the lock 1 itself, as noted during the closure and opening phases, towards the outside and towards the inside of the motor vehicle cell.
  • the shell 17 made of relatively yielding materials allows following closure, slight displacements of lock 1 in relation to the relative striker in such a manner as to compensate for the inevitable assembly play between the door 2 and the respective upright and to greatly reduce the elastic distortion of the door (2) itself, and thereby the consequent emission of unwanted noises during the opening phase.
  • the surrounding 5 could comprise a single plate 15 integrally connected with the door 2 by a plurality of securing components 19; in that case the shell 17 should thus be replaced by components made of relatively yielding materials and allowing their interposition in service, between the plate 15 and the door 2 and between the latter and each of the securing components 19.
  • lock 1 could be fitted to the upright of the door 2 and could cooperate with a striker which is integral with the said door.
