Definitions

  • the present invention relates to a key comprising a key body generally made of metal, elongated, as well as a head attached to one end of the key body.
  • the head constitutes a case containing an electronic device, for example a transponder used for motor vehicle ignition keys.
  • This head is from substantially flat overall shape; its median plane (more plane large section of the head) is parallel to that of the key body, when the key body is flat, and preferably coincides substantially with the latter.
  • the invention remedies this drawback and has in particular aim of proposing a simple realization of a key head of the type defined above comprising a grasping ring.
  • the grip ring is formed by a first piece of the key head, and that the housing is formed by assembling this first part with a second part along a joint surface extending substantially along a plane non-parallel, preferably orthogonal, to the median plane of the head key.
  • this characteristic of the invention makes it possible to carry out a first piece of solid plastic housing in the area of the gripping ring, so that nothing prevents the realization a large gripping ring, which was not the case state of the art case. Finally, it is possible with this type of achievement, to obtain interesting aesthetic effects, particularly in molding the two parts of the case with plastic materials different colors.
  • the joint surface of the parts is advantageously oblique relative to the longitudinal axis of the key body.
  • the part forming a gripping ring constitutes the cover of the housing, and the body of the latter is constituted by the second part which is dig.
  • the first part of the key head forming a ring gripping may include positioning and fixing means of the key body, while the recess of the second head piece of key opens on the outside, on the one hand, by the joint face of said second part and on the other hand, by a face located substantially at the opposite of said seal face, this latter outlet being made by a outlet opening having a section substantially identical to that of the key body.
  • the aforementioned positioning and fixing means may include a stirrup, the space between branches of which is present, seen in plan, a profile producing retaining elements cooperating with additional elements provided on one end of the body of key, this profile being substantially identical in shape to that of the profile, seen in plan, from said end of the key body, said stirrup being shaped and dimensioned so as to receive with a prestress said end of the key body, said stirrup projecting from the joint face of said first key head piece, said recess of the second key head piece being shaped and dimensioned for being able, in the assembled position of the key head, to house said stirrup.
  • the stirrup can be substantially flat and have a thickness lower than that of the key body, a step being provided in an inner sliding surface of the recess of the second key head piece, to, in assembled key position, cooperate with the offset formed by said difference in thickness between the stirrup and the key body, elastic means being provided for biasing the key body against said sliding surface; said elastic means may include a tongue extending to the interior of said recess of the second key head piece, substantially parallel to said sliding surface, the spacing between said tongue and the sliding surface being substantially equal to the thickness of the key body, the free end of said tongue being facing the seal face of said second key head piece.
  • the end of the key body disposed at the interior of the case includes two opposite side notches arranged so that, in the assembled position of the key, extend to the interior of said outlet opening, the free end of each branches of said stirrup being arranged and shaped so as to be able to be accommodated without lateral play in the space delimited by the wall of the notch, on the one hand, and through the wall of said outlet opening and the wall adjacent to the recess of said second key head piece, located to the right of the notch, on the other hand.
  • the first key head piece has a second part projecting from its seal face, this second protruding part having a recess open to the less on the face of said projecting part opposite the stirrup, this recess being intended to receive said electronic device; he can be provided between said tongue and the wall of the recess of the second key head piece, located opposite the surface of sliding, a space for housing said second part in projection, in assembled position of the key head.
  • FIG 1 there is shown in exploded view a key contact for motor vehicle according to the invention.
  • This key includes a key body 1, of metal, of flat and elongated shape, and a head of key forming a case made up of two plastic parts molded 3 and 4.
  • the key head 3, 4 has, in plan view, a shape substantially circular. Its thickness is much less than its diameter. Its median plane P -or plane of greatest extension or large section plane- is parallel to the plane of the key body 1 and is located very small distance from the mean plane of said key body 1.
  • the part 3 constitutes a hollow body of the case, delimiting a recess 30, while the other part 4 forms, on one side, a ring of gripping the key and, on the other side, the housing cover.
  • the housing parts 3 and 4 are assembled according to a substantially planar joint surface SJ which is orthogonal to the median plane P of the key head, and which is oblique to relative to the longitudinal axis AL of the key body 1 (see Figures 2 and 4).
  • a transponder 5 is mounted in the housing 3, 4 by means which will be described later.
  • the housing cover 4 is provided with two substantially flat parts 6 and 7, mutually parallel, spaced from one another, projecting from the joint face 4 a of said cover 4, and extending orthogonally by relative to this face 4a in the direction opposite to the grip ring.
  • the protruding parts 6, 7 are housed in the recess 30 of the housing body 3.
  • the projecting part 6 presents in plan view (see FIG. 5) the shape of a right triangle whose hypotenuse coincides with the joint face 4 a and whose apex angle is approximately 30 °. On the base of the right triangle, the projecting part 6 forms a stirrup 8 whose branches 8 a extend perpendicularly to said base of the triangle.
  • the key body 1 comprises two notches 9 symmetrical to one another, of rectangular shape in plan view, each being formed from the 'one of the longitudinal sections 1b of said key body.
  • Each branch 8 a of the stirrup 8 has, on its face facing the other branch, a raised part 10 of shape corresponding to that of a notch 9.
  • the members 8, 8 a , 10 are arranged and dimensioned to so that the space between branches of the stirrup 8 can receive without play and with a certain preload the end of the key body 1.
  • the stirrup 8 of the projecting part 6 thus constitutes, thanks to the presence of the notches 9 and reliefs 10 which fit into it, a member for positioning and fixing the key body 1.
  • the projecting part 7 is ribbed on its face located opposite to the projecting part 6, and it has in plan view (see FIG. 7) a general shape of right triangle of extension substantially identical to that of the part protruding 6; the edges 6 a , 7 has parts 6 and 7 which constitute the heights of the right triangles are perpendicular to each other and have approximately identical lengths.
  • the protruding part 7 comprises in the zone situated directly above the stirrup 8, a recess 11 open on the face opposite to the stirrup 8, as well as on the edge 7b on the base side of the right triangle that constitutes said part. 7.
  • the recess 11 is only partially open because part 7 comprises, on this side, strips 12 forming a bridge (see FIGS. 6 a and 7).
  • the recess 11 is shaped and dimensioned so as to be able to receive without lateral play and, preferably with a slight prestress, the transponder 5.
  • the housing body 3 is open on its seal face 3 a . It is dimensioned so that in the assembled position of the key head, the projecting parts 6 and 7 are housed in its recess 30.
  • the body 3 is provided with an opening 13, the rectangular section of which is substantially identical to that of the key body 1.
  • the opening 13 is positioned on the body 3 so that in the assembled position of the key, the key body 1 positioned and fixed on the projecting part 6 of the cover 4 passes through said opening 13 substantially without transverse play.
  • Figure 16 shows schematically, in the assembled position, the end 1a of the 1 key body positioned on the caliper of the projecting portion 6, within the body casing 3.
  • the thickness a of the protruding part 6 is less than that, b, of the key body 1.
  • the bottom wall of the opening 13 extends inwards of the body 3 by a flat sliding surface 14 coplanar with said bottom wall.
  • the planar surface 14 ends towards the inside of the body 3 by a recess forming a shoulder face 15 facing the opening 13, followed by a surface of small width 15 a parallel to the surface 14.
  • the recess (15 , 15 a ) is followed, towards the inside of the body 3, by a flat sliding surface 16, inclined relative to the surface 14 in the direction opposite to the direction of the step formed by the shoulder 15.
  • the step 15, 15 a is shaped and positioned so as to cooperate with the step consisting of the difference in thicknesses between the stirrup part 6, 8 and the key body 1, to constitute a means for holding the assembly by clipping (cover 4 + key body 1) into the housing body 3.
  • Elastic means are also provided for urging the key body 1 against the sliding surfaces 16, 14 during the introduction of the key body 1 into the housing body 3.
  • These elastic means consist of a tongue 17 extending inside the housing body 3, from the opening 13, parallel to the sliding surface 14, the free end of said tongue 17 facing the seal face 3 a of the housing body 3.
  • the lower face 17 a (FIG. 14) of the tongue 17 is coplanar with the upper wall of the opening 13 and constitutes an extension towards the interior of the body 3.
  • the spacing c between said lower face 17 a of the tongue 17 and the sliding surface 14 is substantially equal to the thickness b of the key body 1.
  • each branch 8a of the stirrup 8 is arranged and shaped so that its free end is housed without lateral play in the space delimited by the wall of the notch 9, on the one hand, and the wall of said opening 13 as well as the area, located to the right of the notch 9, of the internal wall of the housing body 3, on the other hand. Thanks to this characteristic, the anchoring of the rod 1 in the key head 3, 4 is further strengthened.
