Description

La présente invention se rapporte à un feu de signalisation de véhicule automobile.The present invention relates to a fire motor vehicle signaling.

L'invention se rapporte à des feux de signalisation qui comprennent, généralement, une série de lampes correspondant aux différentes fonctions, lesdites lampes étant masquées par une vitre externe en matière plastique transparente.The invention relates to traffic lights which generally include a series of lamps corresponding to the different functions, said lamps being hidden by an external plastic window transparent.

Les impératifs de la réglementation obligent les fabricants à réaliser la vitre avec des zones présentant des couleurs différentes ce qui est souvent inesthétique.Regulatory imperatives require manufacturers to realize the glass with areas presenting different colors which is often unsightly.

Afin de remédier à cet aspect, on essaie de réaliser des feux qui, vus de l'extérieur, présentent une certaine uniformité.In order to remedy this aspect, we try to make lights which, seen from the outside, present some uniformity.

La présente invention vise un feu du type comprenant une lampe, un réflecteur, un écran disposé devant la lampe et une glace, cette dernière comportant une série de barreaux colorés parallèles à section sensiblement rectangulaire, solidaires d'une épaisseur de matière plastique transparente en ménageant entre chaque paire de barreaux des intervalles, tandis que l'écran présente une face plane et, sur l'autre face, une optique propre à canaliser les rayons lumineux émis par la lampe vers les intervalles.The present invention relates to a fire of the type comprising a lamp, a reflector, a screen arranged in front of the lamp and a mirror, the latter comprising a series of colored bars parallel to section substantially rectangular, integral with a thickness of material transparent plastic, sparing between each pair bars of intervals, while the screen shows one flat side and, on the other side, a clean optic to channel the light rays emitted by the lamp towards the intervals.

Ainsi, le feu a un aspect uniforme et peut néanmoins remplir toutes les fonctions, clignotant, feu de recul, stop, etc...Thus, the fire has a uniform appearance and can nevertheless perform all functions, flashing, light reversing, stop, etc ...

L'invention vise un feu du type ci-dessus défini dont la surface extérieure se prolonge afin de s'étendre latéralement, par exemple, sur le côté du véhicule sans toutefois sortir de la conformité de la réglementation en vigueur.The invention relates to a fire of the above type defined whose outer surface extends in order to extend laterally, for example, on the side of the vehicle without however departing from regulatory compliance in force.

L'un des buts de l'invention est de réaliser un feu dont la partie prolongeant latéralement la glace soit éclairée sans qu'il soit nécessaire de prévoir de moyens d'éclairage supplémentaires qui sont très difficiles à loger dans la structure du véhicule.One of the aims of the invention is to achieve a fire whose part extending laterally the ice is lit without the need to provide additional means of lighting which are very difficult to be housed in the vehicle structure.

L'invention vise un feu de signalisation de véhicule automobile du type comprenant une lampe, un réflecteur, un écran disposé devant la lampe et une glace disposée devant l'écran et qui comporte une série de barreaux colorés parallèles à section sensiblement rectangulaire, solidaires d'une épaisseur de matière plastique transparente en ménageant entre chaque paire de barreaux des intervalles, tandis que l'écran présente une face plane et, sur l'autre face, une optique propre à canaliser les rayons lumineux émis par la lampe vers les intervalles, ledit feu étant caractérisé en ce que la glace comporte un prolongement destiné à s'étendre latéralement le long du véhicule, l'écran présentant un prolongement correspondant, ledit prolongement de l'écran présentant, sur sa face tournée du côté de la lampe, une série de nervures longitudinales dont une extrémité, tournée vers ladite lampe, présente une surface d'entrée optique, des moyens étant prévus pour diffuser la lumière du côté de la face de l'écran tournée en regard de la glace et au droit des nervures.The invention relates to a signaling light for motor vehicle of the type comprising a lamp, a reflector, a screen arranged in front of the lamp and a glass arranged in front of the screen and which has a series of colored bars parallels of substantially rectangular section, integral of a transparent plastic thickness while sparing between each pair of bars of the intervals, while the screen has a flat face and, on the other front, an optic capable of channeling light rays emitted by the lamp at intervals, said fire being characterized in that the glass has an extension intended to extend laterally along the vehicle, the screen having a corresponding extension, said extension of the screen presenting, on its turned side on the side of the lamp, a series of longitudinal ribs one end of which, facing said lamp, has an optical input surface, means being provided to diffuse the light from the side of the screen turned opposite the mirror and in line with the ribs.

Grâce à cette disposition, une partie de la lumière émise par la lampe sera canalisée dans les nervures et s'échappera du côté de l'écran situé en regard de la glace pour passer à travers les intervalles ménagés entre les barreaux. Thanks to this arrangement, part of the light emitted by the lamp will be channeled into the ribs and will escape from the side of the screen located next to the ice to pass through the intervals between bars.

De préférence, les moyens pour laisser passer la lumière du côté de la face de l'écran tournée en regard de la glace et au droit des nervures sont formés par un dépolissage de bandes correspondant aux nervures.Preferably, the means to let pass the light on the side of the face of the screen turned opposite ice and the ribs are formed by a frosting of bands corresponding to the ribs.

Afin que l'intensité de lumière s'échappant par les bandes dépolies soit sensiblement uniforme sur tout le prolongement, le dépolissage des bandes va en croissant depuis la surface d'entrée vers l'extrémité libre des nervures.So that the intensity of light escaping by the frosted bands is substantially uniform over all the extension, the frosting of the bands goes in increasing from the entry surface towards the end free of ribs.

De préférence, la surface d'entrée optique est formée par un biseau orienté vers la source lumineuse.Preferably, the optical input surface is formed by a bevel oriented towards the light source.

Suivant un premier mode de réalisation, la face du prolongement de l'écran, tournée en regard de la lampe, comporte une série de godrons convexes, les nervures s'étendant parallèlement au droit de la jonction des godrons convexes.According to a first embodiment, the face of the extension of the screen, turned opposite the lamp, comprises a series of convex gadroons, the ribs extending parallel to the right of the junction convex gadroons.

Suivant une première variante de réalisation, la face du prolongement de l'écran, tournée en regard de la glace, comporte une série de godrons convexes, les nervures étant situées au droit des jonctions des godrons.According to a first alternative embodiment, the face of the extension of the screen, turned opposite ice, has a series of convex gadroons, the ribs being located at the junction of the gadroons.

Suivant une seconde variante de réalisation, la face du prolongement de l'écran, tournée en regard de la glace, comporte une série de godrons cylindriques concaves, les nervures étant situées au droit des jonctions des godrons cylindriques concaves.According to a second alternative embodiment, the face of the extension of the screen, turned opposite ice, has a series of cylindrical gadroons concave, the ribs being located at the junctions concave cylindrical gadroons.

Suivant encore un autre mode de réalisation, la face du prolongement de l'écran tournée en regard de la lampe, comporte une série de godrons cylindriques concaves, les nervures étant situées au droit des jonctions des godrons cylindriques concaves. According to yet another embodiment, the side of the extension of the screen turned opposite the lamp, comprises a series of concave cylindrical gadroons, the ribs being located at the junctions concave cylindrical gadroons.

Enfin, suivant une dernière variante de réalisation, la série de nervures longitudinales présentent une hauteur qui va en diminuant depuis la surface d'entrée optique jusqu'à l'extrémité libre de celles-ci, la face desdites nervures prolongeant la surface d'entrée optique étant recouverte d'une couche d'un produit diffusant.Finally, according to a last variant, the series of longitudinal ribs have a height which decreases from the entry surface optical to the free end of these, the face said ribs extending the optical input surface being covered with a layer of a diffusing product.

Comme produit diffusant, on peut utiliser de la peinture blanche. Ainsi, le produit diffusant joue le rôle d'une série de lentilles réfléchissantes et la lumière peut traverser l'écran sans qu'il soit nécessaire de réaliser des bandes dépolies compte tenu de l'amplification de l'intensité lumineuse engendrée par la couche dudit produit diffusant. As a diffusing product, it is possible to use white paint. Thus, the diffusing product plays the role of a series of reflective lenses and the light can pass through the screen without it being necessary to produce frosted bands given the amplification of the light intensity generated by the layer of said diffusing product.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés aux dessins annexés, dans lesquels :The invention will now be described with more details with reference to embodiments individuals given by way of example only and shown to the accompanying drawings, in which:

Figure 1 montre en perspective schématique un feu, selon l'invention.Figure 1 shows schematic perspective a fire according to the invention.

Figure 8 est une vue en perspective d'une variante de l'écran.Figure 8 is a perspective view of a screen variant.

Figure 9 est une vue en coupe similaire à la coupe de la figure 3, mais visant un mode de réalisation utilisant l'écran de la figure 8.Figure 9 is a sectional view similar to the section of FIG. 3, but aimed at an embodiment using the screen in Figure 8.

Figure 10 est une vue en coupe suivant la ligne 10-10 de la figure 9. Figure 10 is a sectional view along the line 10-10 of figure 9.

Le feu représenté aux figures 1 et 2 présente une douille 1 destinée à recevoir une lampe 2 et un réflecteur 3.The fire shown in Figures 1 and 2 shows a socket 1 intended to receive a lamp 2 and a reflector 3.

Le réflecteur 3 est masqué par un écran 4 qui est transparent et qui peut être, suivant les différentes utilisations, incolore, ou légèrement coloré, rouge, vert, ambre, etc...The reflector 3 is masked by a screen 4 which is transparent and which can be, according to the different uses, colorless, or slightly colored, red, green, amber, etc ...

Dans le mode de réalisation des figures 1 à 4, l'écran 4 comporte, sur sa face 4a tournée vers la lampe 2, une série de godrons convexes 5, tandis que la face opposée 4b est plane.In the embodiment of Figures 1 at 4, the screen 4 comprises, on its face 4a facing the lamp 2, a series of convex gadroons 5, while the opposite face 4b is planar.

L'écran 4 est masqué par une glace 7 qui est formée d'une série de barreaux parallèles 8 de couleur rouge qui sont solidaires, par leur face tournée vers l'extérieur, d'une épaisseur 9 d'une matière plastique incolore, un intervalle incolore 9a étant ménagé entre chaque paire de barreaux 8. Les barreaux 8 ont une section sensiblement rectangulaire et dans ce mode de réalisation s'étendent parallèlement horizontalement, mais pourraient parfaitement être situés verticalement.The screen 4 is masked by a glass 7 which is formed of a series of parallel bars 8 of color which are united, by their face turned towards the outside, of a thickness 9 of a plastic material colorless, a colorless interval 9a being provided between each pair of bars 8. The bars 8 have a section substantially rectangular and in this embodiment extend parallel horizontally but could perfectly be located vertically.

Les rayons lumineux émis par la lampe 2 sont, grâce à l'écran 4, concentrés dans les intervalles 9a.The light rays emitted by the lamp 2 are, through screen 4, concentrated in intervals 9a.

Les intervalles 9a sont suffisamment étroits pour que l'observateur, situé en regard du feu, ne voie qu'un aspect général rouge lorsque le feu est éteint, mais suffisamment grand pour laisser passer la lumière émise par la lampe 2.The intervals 9a are sufficiently narrow so that the observer, located opposite the fire, does not see that a general red appearance when the fire is out, but big enough to let the light through emitted by the lamp 2.

Si l'écran 4 est incolore et la lampe 2 blanche, la lumière traversant les intervalles 9a sera blanche. Si on veut obtenir une lumière colorée, l'écran 4 ou la lampe 2 sera coloré.If screen 4 is colorless and lamp 2 is white, the light passing through the intervals 9a will be white. If you want to obtain a colored light, screen 4 or the lamp 2 will be colored.

Conformément à l'invention, la glace 7 est pourvue d'un prolongement 17 qui est destiné à s'étendre sur la paroi latérale du véhicule, l'écran 4 comportant un prolongement 18 correspondant.According to the invention, the glass 7 is provided with an extension 17 which is intended to extend on the side wall of the vehicle, the screen 4 comprising a corresponding extension 18.

Le prolongement 17 de la glace 7 est réalisé de la même façon que ladite glace avec une série de barreaux parallèles 8 rouges qui sont solidaires, par leur face tournée vers le prolongement 18 de l'écran 4, d'une épaisseur 9 de matière plastique incolore, un intervalle incolore 9a étant ménagé entre chaque paire de barreaux 8.The extension 17 of the glass 7 is made in the same way as said ice with a series of bars 8 red parallels which are united by their face facing the extension 18 of the screen 4, of a thickness 9 of colorless plastic, a colorless gap 9a being formed between each pair of bars 8.

Le prolongement 18 de l'écran 4 présente, sur la face 4a, une série de godrons convexes 5 et la face 4b tournée vers la glace est plane.The extension 18 of the screen 4 presents, on the face 4a, a series of convex gadroons 5 and the face 4b facing the ice is flat.

Entre chaque godron 5, le prolongement 18 de l'écran 4 comporte une nervure 20.Between each gadroon 5, the extension 18 of screen 4 has a rib 20.

Chaque nervure 20, du côté de son extrémité tournée vers la lampe 2, présente une surface d'entrée optique qui peut être formée par un biseau 21 afin de capter le plus de lumière possible issue de ladite lampe 2.Each rib 20, on the side of its end facing lamp 2, has an entry surface optic which can be formed by a bevel 21 in order to capture as much light as possible from said lamp 2.

Toute les faces des nervures 20 sont parfaitement polies afin de retenir la lumière entrant par le biseau 21. Les biseaux des différentes nervures peuvent avoir des inclinaisons différentes, suivant leur position par rapport à la lampe 2.All the faces of the ribs 20 are perfectly polished to retain light entering through the bevel 21. The bevels of the different ribs can have different inclinations, depending on their position relative to the lamp 2.

La partie de la face 4b du prolongement 18 de l'écran 4 présente, au droit de chaque nervure 20, une bande dépolie 22. De préférence, ces bandes comportent un dépolissage qui va croissant depuis l'extrémité du prolongement 18 adjacent à un biseau 21 jusqu'à son extrémité libre. Ainsi, la lumière captée dans les nervures 20 s'échappera à travers la bande dépolie correspondante de manière que le prolongement 17 soit éclairé sur toute sa longueur.The part of the face 4b of the extension 18 of screen 4 has, at the right of each rib 20, a frosted strip 22. Preferably, these strips comprise a frosting which increases from the end of the extension 18 adjacent to a bevel 21 to its end free. Thus, the light captured in the ribs 20 will escape through the corresponding frosted strip so that the extension 17 is lit all over its length.

A la figure 5, on a représenté une variante de réalisation dans laquelle l'écran 10 qui correspond au prolongement 18 de l'écran 4 présente, sur sa face 10b, tournée en regard du prolongement 17 de la glace 7, une série de godrons convexes 11, tandis que la face opposée 10a tournée en regard de la lampe est plane et comporte une série de nervures 20a parallèles entre elles, l'intervalle entre les godrons 11 et situé au droit des nervures 20a étant formé d'une bande dépolie 22a. De préférence, le dépolissage est croissant depuis le biseau 21 jusqu'à l'extrémité libre des nervures. La lumière captée par les nervures 20a s'échappera à travers les bandes dépolies et traversera les intervalles 9a.In FIG. 5, a variant has been represented. of realization in which the screen 10 which corresponds to the extension 18 of the screen 4 present, on its face 10b, turned opposite the extension 17 of the ice 7, a series of convex gadroons 11, while the face opposite 10a facing the lamp is flat and comprises a series of ribs 20a parallel to each other, the interval between the gadroons 11 and located to the right of the ribs 20a being formed from a frosted strip 22a. Preferably, the frosting is increasing from the bevel 21 to the free end of the ribs. Light captured through the ribs 20a will escape through the strips frosted and will cross the intervals 9a.

A la figure 6, on a représenté une troisième forme d'exécution de l'invention. Dans cette réalisation, l'écran 12 qui correspond au prolongement 18 de l'écran 4, sur sa face 12a tournée vers la lampe 2, présente une surface plane, tandis que l'autre face 12b, tournée en regard du prolongement 17 de la glace 7, présente une série de godrons cylindriques concaves 13. La face 12a est pourvue d'une série de nervures 20b s'étendant parallèlement au droit de la jonction des godrons cylindriques concaves 13, tandis que la jonction desdits godrons, sur la face 12b, est dépolie pour former des bandes 22b dont le dépolissage va en croissant depuis les biseaux 21 jusqu'à l'extrémité libre desdites nervures 20b. In Figure 6, a third is shown embodiment of the invention. In this realization, screen 12 which corresponds to the extension 18 of the screen 4, on its face 12a facing the lamp 2, has a flat surface, while the other face 12b, turned in look of the extension 17 of the glass 7, presents a series of concave cylindrical gadroons 13. Face 12a is provided with a series of ribs 20b extending parallel at the junction of the cylindrical gadroons concaves 13, while the junction of said gadroons, on the face 12b, is frosted to form strips 22b of which the frosting is increasing from the bevels 21 to the free end of said ribs 20b.

La figure 7 montre encore une autre variante de l'invention. Le prolongement 17 de la glace 7 est du même type que les prolongements 17 des différentes figures précédentes. Le prolongement 18 de l'écran 4 désigné par la référence 14 présente une face 14a avec une série de godrons cylindriques concaves 15 tournés du côté de la lampe et une face 14b plane.Figure 7 shows yet another variant of the invention. The extension 17 of the glass 7 is of the same type as the extensions 17 of the different figures previous. Extension 18 of screen 4 designated by reference 14 presents a face 14a with a series of concave cylindrical gadroons 15 turned on the side of the lamp and a flat face 14b.

Dans cette réalisation, les nervures 20c sont situées au droit des jonctions des godrons 15, la face 14b présentant, au droit des nervures 20, des bandes dépolies 22c dont le dépolissage est croissant depuis le biseau 21 jusqu'à l'extrémité libre desdites nervures 20c.In this embodiment, the ribs 20c are located at the junction of the gadroons 15, the face 14b presenting, in line with the ribs 20, frosted bands 22c whose frosting is increasing from the bevel 21 to the free end of said ribs 20c.

Le prolongement 17 de la glace 7 est constitué de la même manière que dans les modes de réalisation précédents.The extension 17 of the glass 7 is constituted in the same manner as in the previous embodiments.

Les figures 8, 9 et 10 montrent une variante de réalisation de l'invention dans laquelle l'écran 24 présente, sur sa face 24a, des godrons convexes 25 et sur son prolongement 18, du côté de la face 24a entre lesdits godrons, des nervures 20d. La face 24b de l'écran 24, dans ce mode de réalisation, ne comporte pas de bandes dépolies, mais on pourrait bien en conformer.Figures 8, 9 and 10 show a variant of the invention in which the screen 24 has, on its face 24a, convex gadroons 25 and on its extension 18, on the side of the face 24a between said gadroons, ribs 20d. The 24b side of the screen 24, in this embodiment, does not include frosted bands, but we could well conform.

Chaque nervure 20d présente, du côté de son extrémité tournée vers la lampe 2, un biseau 21a, et la hauteur de chaque dite nervure 20d va en diminuant depuis la nervure jusqu'à son extrémité libre.Each rib 20d has, on the side of its end turned towards the lamp 2, a bevel 21a, and the height of each said rib 20d decreases since the rib to its free end.

Les biseaux 21a constituent des surfaces d'entrée optique qui sont destinées à capter le plus de lumière possible issue de la lampe 2. The bevels 21a constitute entry surfaces optics that are meant to capture the most light possible from lamp 2.

Afin que la lumière captée par les nervures 20d et s'échappant par la face 24b ait le maximum d'intensité, la face des nervures 20d prolongeant les biseaux 21a est revêtue d'une couche d'un produit diffusant tel que de la peinture blanche 26. Ainsi, cette peinture constitue une multitude de lentilles réfléchissantes qui renvoient la lumière à travers la face 24b, suivant les lignes correspondant aux nervures 20d.So that the light captured by the ribs 20d and escaping through the face 24b has the maximum intensity, the face of the ribs 20d extending the bevels 21a is coated with a layer of a diffusing product such as white paint 26. So this paint is a multitude of reflective lenses which reflect the light through the face 24b, along the corresponding lines to the ribs 20d.

Le prolongement 17 de la glace 7 est réalisé de la même façon que dans les autres modes de réalisation.The extension 17 of the glass 7 is made in the same way as in the other embodiments.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and represented. We can make many modifications detail without departing from the scope of the invention.
