Abstract
Description
La présente invention est relative à un feu de véhicule, notamment automobile, comportant des moyens pour le centrage de son transparent par rapport à la carrosserie dudit véhicule. The present invention relates to a vehicle light, in particular a motor vehicle light, comprising means for centering its transparency relative to the body of said vehicle.
Classiquement, un feu de véhicule comporte un socle définissant une ou plusieurs cavités dans le fond desquelles sont disposées des lampes, le feu comportant également au moins un transparent fermant une cavité. Conventionally, a vehicle light comprises a base defining one or more cavities in the bottom of which lamps are arranged, the light also comprising at least one transparency closing a cavity.
De façon classique, on positionne un tel feu dans l'évidement de la carrosserie sur lequel il est monté au moyen d'inserts de fixation que présente le feu, ces inserts s'engageant dans des trous complémentaires de la carrosserie. Ces inserts sont éventuellement complétés par un ou plusieurs centreurs, qui sont des éléments s'étendant à partir du socle et s'engageant dans des trous complémentaires que présente la tôle de la carrosserie. Conventionally, such a light is positioned in the recess of the bodywork on which it is mounted by means of fixing inserts that the light has, these inserts engaging in complementary holes in the bodywork. These inserts are optionally supplemented by one or more centralizers, which are elements extending from the base and engaging in complementary holes that the sheet metal of the body has.
Dans certains cas, il n'est pas possible de prévoir des moyens de fixation du type à inserts ou centreurs. C'est notamment le cas sur les carrosseries en matière plastique ou encore sur les carrosseries ne permettant pas l'accès à l'arrière du feu. La fixation est alors assurée, par exemple, par des agrafes solidaires du socle et pincées par vissage sur le bord de la carrosserie. De tels moyens de fixation ne permettent pas un centrage précis du feu par rapport à la tôle de la carrosserie. In some cases, it is not possible to provide fixing means of the insert or centering type. This is particularly the case on plastic bodies or on bodies which do not allow access to the rear of the light. The fixing is then ensured, for example, by staples secured to the base and pinched by screwing on the edge of the bodywork. Such fixing means do not allow precise centering of the light relative to the sheet metal of the bodywork.
En outre, pour être efficace, le centrage du type à inserts et centreurs nécessite qu'au moins deux zones de centrage soient prévues entre la carrosserie et le socle. In addition, to be effective, centering of the insert and centering type requires that at least two centering zones are provided between the bodywork and the base.
Dans le cas où un seul insert de fixation est suffisant pour remplir la fonction "fixation", il peut s'avérer difficile de prévoir un centreur et un trou complémentaire sur la carrosserie à la seule fin d'assurer un centrage convenable du feu par rapport à la tôle.If a single fixing insert is sufficient to fulfill the "fixing" function, it may prove difficult to provide a centering device and an additional hole on the bodywork for the sole purpose of ensuring proper centering of the light relative to to the sheet metal.
Egalement, le centrage obtenu avec des moyens du type à inserts ou centreurs nécessite une grande précision de positionnement des trous et inserts de la carrosserie. Also, the centering obtained with means of the type with inserts or centralizers requires great precision in positioning the holes and inserts of the body.
I1 est toujours limité aux tolérances de fabrication entre, d'une part, les trous de fixation ou de centrage et, d'autre part, les inserts ou les centreurs. I1 is always limited to the manufacturing tolerances between, on the one hand, the fixing or centering holes and, on the other hand, the inserts or the centralizers.
La présente invention propose une solution qui permet de pallier les différents inconvénients précités. The present invention provides a solution which overcomes the various aforementioned drawbacks.
A cet effet, le feu, selon l'invention, est un feu de véhicule, notamment automobile, comportant un socle présentant au moins une cavité dans le fond de laquelle est disposée une lampe, au moins un transparent étant fixé sur ledit socle et fermant cette cavité, ledit socle et ledit transparent étant reçus dans un logement de la carrosserie, des moyens permettant le centrage du transparent par rapport audit logement, caractérisé en ce que ces moyens de centrage comportent au moins un plot de centrage s'interposant entre, d'une part, les parois du logement et, d'autre part, le transparent et/ou le socle. To this end, the light according to the invention is a vehicle light, in particular a motor vehicle light, comprising a base having at least one cavity in the bottom of which is a lamp, at least one transparent being fixed on said base and closing this cavity, said base and said transparent being received in a housing of the body, means allowing the centering of the transparent relative to said housing, characterized in that these centering means comprise at least one centering pad interposed between, d on the one hand, the walls of the housing and, on the other hand, the transparency and / or the base.
D'autres caractéristiques et avantages ressortiront encore de la description qui suit d'un mode de réalisation particulier de l'invention. Cette description est purement illustrative et non limitative. Other characteristics and advantages will emerge from the following description of a particular embodiment of the invention. This description is purely illustrative and not limiting.
Elle doit être lue en regard des dessins annexés sur lesquels
la figure 1 est une vue en coupe d'un feu conforme à l'invention
la figure 2 est une vue de dessus avec arraché du feu de la figure i
la figure 3 est une vue en coupe selon la ligne
III-III de la figure 2.It should be read in conjunction with the accompanying drawings on which
Figure 1 is a sectional view of a light according to the invention
Figure 2 is a top view with cutaway of the light of Figure i
Figure 3 is a sectional view along the line
III-III of figure 2.
De façon classique, le feu représenté sur ces figures comporte un socle 1, qui comprend au moins une cavité 2. Cette cavité 2 est, telle que représentée, réfléchissante et de forme parabolique. Elle présente un fond 2a et est fermée par un transparent 3. Selon la fonction à laquelle le feu correspond (feu indicateur de direction, feu de recul, feu stop), le transparent est coloré ou non. Conventionally, the light shown in these figures comprises a base 1, which comprises at least one cavity 2. This cavity 2 is, as shown, reflective and of parabolic shape. It has a bottom 2a and is closed by a transparency 3. Depending on the function to which the light corresponds (direction indicator light, reversing light, stop light), the transparent is colored or not.
Dans cette cavité 2 est disposée une lampe 4. Le culot 5 de cette lampe 4 traverse le fond 2a et est reçu dans un porte-lampe 6 porté par le socle 1. In this cavity 2 is placed a lamp 4. The base 5 of this lamp 4 passes through the bottom 2a and is received in a lamp holder 6 carried by the base 1.
Le socle 1 présente un rebord annulaire 7 qui prolonge les parois définissant la cavité 2 en s'étendant du contour d'ouverture de ladite cavité 2 vers l'extérieur de celle-ci, perpendiculairement auxdites parois. The base 1 has an annular rim 7 which extends the walls defining the cavity 2 by extending from the opening contour of said cavity 2 towards the outside thereof, perpendicular to said walls.
La tôle 8 de la carrosserie est conformée avec un renfoncement R formant logement, dans lequel est reçu le socle 1. Le renfoncement R comporte un fond 9 bordé par des parois latérales 10. Sur le fond 9 est ménagé un évidement 11, le contour de cet évidement 11 correspondant sensiblement au contour extérieur du socle 1 au voisinage de l'ouverture de la cavité 2. The sheet metal 8 of the bodywork is shaped with a recess R forming a housing, in which is received the base 1. The recess R has a bottom 9 bordered by side walls 10. On the bottom 9 is formed a recess 11, the contour of this recess 11 corresponding substantially to the external contour of the base 1 in the vicinity of the opening of the cavity 2.
Le rebord 7 est porté par le bord de 1 'évidement 11 que constitue le fond 9 du renfoncement R, un joint 12 étant interposé entre ledit fond 9 et ledit rebord 7. Le rebord 7 présente une protubérance annulaire 13, qui s'étend sur tout le pourtour dudit rebord 7 et qui est en saillie par rapport à la face de celui-ci destinée à être en regard du fond 9. Cette protubérance annulaire 13 assure par compression du joint 12, l'étanchéité entre le rebord 7 et le fond 9. The rim 7 is carried by the edge of the recess 11 formed by the bottom 9 of the recess R, a seal 12 being interposed between said bottom 9 and said rim 7. The rim 7 has an annular protuberance 13, which extends over the entire periphery of said rim 7 and which projects from the face thereof intended to be opposite the bottom 9. This annular protrusion 13 ensures by compression of the seal 12, the seal between the rim 7 and the bottom 9.
Le transparent 3 présente un rebord périphérique 14, ainsi qu'une jupe 15 au voisinage dudit rebord 14. Ce rebord 14 et cette jupe 15 s'étendent tous deux vers le rebord 7, à partir de la face dudit transparent 3 qui est dirigée vers l'intérieur de la cavité 2, le contour de la jupe 15 étant à l'intérieur du contour du rebord 14. The transparency 3 has a peripheral rim 14, as well as a skirt 15 in the vicinity of said rim 14. This rim 14 and this skirt 15 both extend towards the rim 7, starting from the face of said transparency 3 which is directed towards inside the cavity 2, the outline of the skirt 15 being inside the outline of the rim 14.
Le transparent 3 est fixé au socle 1 par tous moyens appropriés, tels qu'une soudure à chaud, une soudure par vibrations, ou un collage au niveau de la jupe 15. The transparency 3 is fixed to the base 1 by any suitable means, such as hot welding, vibration welding, or bonding at the level of the skirt 15.
Le feu est fixé à la tôle 8 par une vis 16, qui s'étend à travers le transparent 3, le rebord 7, le joint 12 et le fond 9. The light is fixed to the sheet 8 by a screw 16, which extends through the transparent 3, the rim 7, the seal 12 and the bottom 9.
La tête de cette vis 16 est en appui sur la face externe d'un logement du transparent 3, dans lequel elle est reçue. Son extrémité opposée présente un filetage qui coopère avec un écrou complémentaire solidaire de la tôle 8. The head of this screw 16 is supported on the external face of a housing of the transparent 3, in which it is received. Its opposite end has a thread which cooperates with a complementary nut integral with the sheet 8.
La face externe du rebord 14 est légèrement espacée des parois 10 du renfoncement R. The outer face of the rim 14 is slightly spaced from the walls 10 of the recess R.
Conformément à l'invention, cette face présente une pluralité de plots 18 en saillie. Ces plots 18 sont en contact avec les parois 10 et assurent un centrage exact du transparent 3 par rapport au renfoncement R. According to the invention, this face has a plurality of studs 18 projecting. These studs 18 are in contact with the walls 10 and ensure exact centering of the transparent 3 relative to the recess R.
En outre, la tranche du rebord 14 est légèrement espacée du rebord 7, de sorte que lors du montage ou du démontage du feu, ce rebord 14 peut se déformer élastiquement lorsque les plots 18 de centrage sont sollicités par les parois du renfoncement R. In addition, the edge of the rim 14 is slightly spaced from the rim 7, so that during assembly or disassembly of the light, this rim 14 can deform elastically when the centering studs 18 are biased by the walls of the recess R.
En variante, les plots de positionnement peuvent être issus de la carrosserie elle-même, si la technologie de fabrication de celle-ci le permet. C'est notamment le cas avec les carrosseries plastiques thermoformées. As a variant, the positioning pads may come from the bodywork itself, if the manufacturing technology thereof allows it. This is particularly the case with thermoformed plastic bodies.
Egalement, les plots 18 de positionnement pourront être issus du socle 1 du feu, le positionnement obtenu étant néanmoins moins satisfaisant que dans le cas où les plots sont portés par le transparent, la pièce principale à centrer dans le renfoncement étant la pièce visible, c'est-à-dire le transparent. Also, the positioning studs 18 may come from the base 1 of the light, the positioning obtained being nevertheless less satisfactory than in the case where the studs are carried by the transparent, the main part to be centered in the recess being the visible part, c that is to say the transparent.
On ajuste l'alignement de la face externe du transparent 3 par rapport à la face externe de la carrosserie de part et d'autre du renfoncement R, en jouant sur l'écrasement du joint 12. The alignment of the external face of the transparency 3 is adjusted relative to the external face of the body on either side of the recess R, by playing on the crushing of the seal 12.
L'on peut en outre prévoir des butées assurant le positionnement précis des deux faces externes précitées l'une par rapport à l'autre. It is also possible to provide stops ensuring the precise positioning of the two above-mentioned external faces relative to one another.
