Definitions

  • the present invention relates generally to devices lighting or signaling for motor vehicles, and more particularly a device comprising a base carrying a lamp which emits a light beam to the outside, a window closing a front opening of the base, an intermediate screen able to be engaged in the base by its front opening and means for holding the screen intermediate in the base.
  • the bonding of the intermediate screen in the base requires precise positioning of said screen inside the base and the respect of the adhesive setting times between the different materials constituting the screen and the base. If these conditions are not met, in during use of the fire, the screen can become detached from the base.
  • the present invention proposes a light in which the means for holding the intermediate screen in the base are simplified and more economical.
  • said holding means on the one hand comprise means forming rear stops provided at the interior of the base and on which comes to bear at least one edge of the intermediate screen and on the other hand a retaining tab towards the front of the intermediate screen which extends towards the front opening of said base to from an edge of the screen and which cooperates by elastic snap-fastening with an interior arrangement of said base.
  • Figure 1 is a side view in longitudinal section of the light according the invention.
  • Figure 2 is a perspective view of part of the fire of the figure 1.
  • Figure 3 is a bottom perspective view of part of the light Figures 1 and 2.
  • a signal light for vehicle automobile here a flashing light
  • a flashing light which comprises a base 10 having a essentially parabolic bottom 10d, upper cheek 10a and a lower cheek 10b.
  • the base is open at the front and has in said bottom a lamp hole 10c.
  • the base 10 is able to carry a lamp (not shown), the filament of which is in the vicinity of the hearth of the parabolic background.
  • the base is made of molded plastic and its interior walls are intended to be covered with a material reflecting the light emitted by the lamp to form a beam bright outward.
  • the flashing light in Figure 1 includes an indicator light (not shown) for closing the front opening of the base 10.
  • the base 10 comprises a ventilation duct 13 opening upwards at 13a near the front edge from the lower cheek 10b and emerging at 13b backwards below cheek 10b. This duct 13 is made in one piece with the base 10.
  • FIG 3 there is a ventilation member 30 of the fire flashing light, well known to those skilled in the art and consisting of a cassette "T" shaped with three openings, one longitudinal opening and two openings side, which communicate with each other.
  • This "T” cassette is arranged below the cheek 10b and is inserted into the ventilation duct 13 through its rear opening 13b, so that the longitudinal opening of said cassette is engaged in said orifice 13b.
  • a tooth attachment 31 engages with the rear edge of the orifice 13a by elastic return following its erasing downwards suffered during inserting the cassette to lock the cassette in position.
  • the fire includes an intermediate screen 20 intended to be placed inside the base 10 behind the indicator.
  • This screen intermediate made of molded plastic is here a style screen able to give the flashing light extinguished an aluminized appearance. It includes this effect a set of thin vertical stripes aluminized 200 separated by transparent parts 201.
  • the intermediate screen 20 is supported in top and bottom respectively on shoulders forming stops 11,12 provided projecting from the upper and lower cheeks 10a, 10b of said base 10. It should be noted that the cheeks 10a, 10b are slightly flared forward from the stops 11,12 to facilitate the installation of the screen intermediate in the base 10. For this installation, we introduce the screen in the base by its front opening so that the edges upper and lower of said screen run along the cheeks 10a, 10b until coming into support on the stops 11,12. These stops 11,12 preferably came from molding.
  • the screen intermediate 20 has at its base a tab 21 for retaining forward.
  • This tab 21 molded with the screen, extends from the edge lower of said screen following the slight slope of the lower cheek 10b when said screen is put in place.
  • the retaining tab 21 is positioned so as to extend above the orifice 13a of the ventilation duct 13.
  • This retaining tab 21 includes a latching tooth 22 which extends downward essentially perpendicular to said tab 21 and which is intended to engage in the orifice 13a to come and cooperate with the front edge 13c of said orifice, this edge 13c being constituted by a part with a descending lip 10th extending along the anterior edge of the cheek 10b.
  • the retaining tab 21 towards the front of the intermediate screen 20 has a central recess 23, here essentially shaped rectangular.
  • This recess has the dual purpose (a) of giving the paw 21 the elasticity necessary for erasing the tooth 22 upwards until its engagement by elastic return in the orifice 13a, and (b) of make the ventilation duct 13 communicate with the interior of the base 10 to effectively provide ventilation.
  • the retaining tab 21 when snapped in, it covers the first orifice 13a and the recess 23 then allows air circulation between the ventilation cassette 30 and the interior of the base 10, via the duct ventilation 13.
  • the screen 20 comprises along at least one of its edges, for example a side edge, at least one notch to ensure ventilation of the space generally closed defined by screen 20 and base 10.
  • the shoulders 11.12 can alternatively be provided on side cheeks of the base.
  • a simple notch is provided in the lower cheek allowing engagement of tooth 22.
