Definitions

  • the present invention relates to the field of automotive equipment. It relates more particularly to a lighting or signaling device for a vehicle.
  • the present invention aims to propose a new equipment of this kind which allows both to achieve effective ventilation, without entry of water or mud, while being simple and economical to achieve.
  • glass means a cover or other wall element of transparent or translucent material intended to be made integral with the housing of a lighting or signaling device for a vehicle, and through which the light rays are diffused.
  • the lighting device according to the invention has not been shown as a whole.
  • a housing 1 housing a concentration mirror. At the bottom of the mirror is mounted a lamp.
  • the housing receives in a sealed manner, on a front opening, a lens, for example made of translucent plastic.
  • the housing and the glass are sealed together, for example by means of a seal.
  • FIG. 1 is shown part of the bottom wall 10 of the housing 1, the latter being made of plastic.
  • This wall is equipped with an external conduit 2 which communicates, as is well known, the interior of the housing with the exterior.
  • the vertical wall of this conduit is formed by the bottom wall 10 of the housing.
  • the wall forms a part projecting towards the interior of the latter, delimited by two wall portions 100 and 101.
  • the first 100 is oblique and has a concave shape while that the second 101 extends vertically upwards and parallel to the bottom wall 10 of the housing.
  • the conduit 2 extends in a generally descending direction and has a lower opening 20 of width substantially less than that of the conduit.
  • the duct is delimited, as already specified, at its bottom by the wall 10. Its periphery is formed by a wall 11 which extends perpendicular to the wall 10 and which comes from molding with it.
  • a bottom wall 60 of a plug 6 for example of plastic or elastomer.
  • This plug has a shape complementary to that of the conduit and adapts perfectly so as to make it perfectly sealed.
  • the duct has, in front view, an oblong shape which is similar to that of an oval.
  • the longitudinal median plane materialized by the XY axis constitutes a plane of symmetry.
  • the device comprises a through tube 3 which is arranged projecting downwards inside the duct.
  • the tube is formed of two parallel partitions 30, perpendicular to the wall 10 and symmetrical to each other with respect to the axis XY. These partitions are molded with the housing 1 and extend over the entire thickness of the conduit, up to the plug 6.
  • This tube is interrupted at its upper end, at the base of the wall portion 100, by a rounded connection zone 31.
  • the tube has a cross section smaller than that of the conduit and the two partitions 30 are each connected to the two parallel lateral faces 110 of the conduit 2 by the curved connection walls 31.
  • the device according to the invention further comprises an element 4 forming a screen. It is arranged directly above and below the lower opening 32 of the tube 3.
  • this element has a cross section in the shape of a "V" with its concave face 40 facing the side of the opening 20 of the duct 2. It is constituted by a tongue coming from molding with the housing 1 and extending perpendicular to the wall 10.
  • the width of this element is substantially close to that of the tube 3 and that of the opening 20.
  • This device makes it possible to achieve perfect ventilation of the housing since the air can circulate freely between the opening 20 of the conduit and the interior of the housing, via the opening 5 (see double arrow in phantom in Figure 3).
  • FIG. 4 The embodiment illustrated in Figures 4 to 6 has the same general structure as the previous embodiment so that the description made for it is valid here. However, it differs from it by the fact that the duct affects, in front view (see FIG. 5) a shape which is similar to that of an ellipse.
  • the longitudinal median plane materialized by the XY axis constitutes a plane of symmetry.
  • the bottom wall 10 has a projection 7 in the form of a plate which extends between the partitions 30.
  • This projection has the same curvature as the connection walls 31. It extends only over part of the thickness of the conduit 2, so as to leave between it and the plug 6, a free space.
  • This projection forms a low wall whose function will be explained in the following description.
  • the element 4 has a section in the form of an arc of a circle with its concave face facing the opening 20.
  • the screen element has a width close to that of the duct, but a smaller depth.
  • the position of the tube 3 is adapted accordingly.
  • the projection 7 extends between the passage 5 and the top of the tube 3. It can be in the form of a flat plate.
