Abstract
Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente invention concerne une pièce de carrosserie de véhicule automobile, notamment un bouclier, munie d'un décor en partie centrale. The present invention relates to a bodywork part of a motor vehicle, in particular a shield, provided with a decoration in the central part.
Le spécialiste des pièces de carrosserie sait que, lorsque ces dernières sont réalisées en matière plastique, il est pratiquement inévitable, en l'état actuel des techniques d'injection et/ou d'aspiration, d'éviter l'apparition de défauts dans leurs zones planes ou sensiblement planes. The specialist in bodywork parts knows that, when the latter are made of plastic, it is practically inevitable, in the current state of injection and / or aspiration techniques, to avoid the appearance of faults in their flat or substantially flat areas.
Une fois revêtues de leur couche de peinture, et éventuellement de vernis, de telles pièces ne présentent plus les défauts de surface précités car ils sont dissimulés sous la peinture. Once coated with their layer of paint, and possibly varnish, such parts no longer have the aforementioned surface defects because they are hidden under the paint.
Cependant, lorsqu'il s'agit de réaliser un décor en partie centrale de la pièce, apparaît la difficulté supplémentaire consistant à maroufler la pièce à la périphérie de sa zone centrale devant recevoir le décor. However, when it comes to making a decoration in the central part of the room, the additional difficulty appears which consists in rolling the piece to the periphery of its central zone which is to receive the decoration.
En outre, la réalisation du décor par peinture en zone centrale limite les possibilités esthétiques à un choix de couleurs et de brillances. In addition, the realization of the decoration by painting in the central zone limits the aesthetic possibilities to a choice of colors and shine.
La présente invention vise à proposer une nouvelle pièce de carrosserie présentant un décor en partie centrale mais dont la réalisation ne nécessite aucun marouflage et qui offre de très nombreuses possibilités esthétiques en comparaison avec les pièces peintes. The present invention aims to provide a new bodywork part with a decoration in the central part but whose production requires no masking and which offers many aesthetic possibilities in comparison with painted parts.
La présente invention a pour objet une pièce de carrosserie de véhicule automobile comportant une partie centrale munie d'un décor, cette pièce étant caractérisée en ce que ladite partie centrale présente une section sensiblement rectiligne et est recouverte par un film surmoulé dont la périphérie délimite strictement ladite zone centrale. The present invention relates to a motor vehicle body part comprising a central part provided with a decoration, this part being characterized in that said central part has a substantially rectilinear section and is covered by an overmolded film whose periphery strictly delimits said central area.
Grâce à sa section sensiblement rectiligne, la zone centrale de la pièce de carrosserie selon l'invention présente une forme cylindrique, au sens mathématique de ce terme, c'est-à-dire qu'elle est engendrée par une droite qui se déplace parallèlement à elle-même en s'appuyant sur une courbe directrice. Thanks to its substantially rectilinear section, the central area of the bodywork part according to the invention has a cylindrical shape, in the mathematical sense of this term, that is to say that it is generated by a straight line which moves parallel to itself by relying on a guide curve.
La courbe directrice peut être une droite, auquel cas la partie centrale forme une facette plane. Si la courbe directrice est une portion de cercle, d'ellipse ou, de manière plus générale, de conique, la partie centrale est bombée. The directing curve can be a straight line, in which case the central part forms a planar facet. If the directing curve is a portion of a circle, ellipse or, more generally, of conic, the central part is curved.
Grâce à l'invention, le fait que la périphérie du film délimite la zone centrale permet d'éviter les problèmes de correspondance de couleurs entre les parties peintes de la carrosserie et ledit film, une bande de matière plastique brute ou teintée dans la masse constituant la pièce de carrosserie étant présente entre le film et les autres parties périphériques de la carrosserie. Thanks to the invention, the fact that the periphery of the film delimits the central zone makes it possible to avoid the problems of color correspondence between the painted parts of the bodywork and said film, a strip of raw plastic material or tinted in the mass constituting the bodywork part being present between the film and the other peripheral parts of the bodywork.
Afin de faciliter la compréhension de l'invention, un exemple de réalisation va maintenant en être décrit à partir de la figure unique annexée qui représente l'avant d'un véhicule automobile. In order to facilitate understanding of the invention, an exemplary embodiment will now be described from the single appended figure which represents the front of a motor vehicle.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
L'avant de ce véhicule est constitué par un capot 1 prolongeant un pare-brise 2 jusqu'à un bouclier 3 qui s'étend sensiblement verticalement jusqu'en partie inférieure de la caisse du véhicule. The front of this vehicle consists of a cover 1 extending a windshield 2 to a shield 3 which extends substantially vertically to the lower part of the vehicle body.
Le bouclier 3 comporte une zone porte-plaques 4 et une prise d'air 5. The shield 3 comprises a plate-carrying zone 4 and an air intake 5.
La zone centrale 6 du bouclier est située entre son bord supérieur 7 voisin du capot 1 et le bord supérieur 8 de la prise d'air 5. The central zone 6 of the shield is located between its upper edge 7 adjacent to the cover 1 and the upper edge 8 of the air intake 5.
Ainsi qu'on le voit sur la gauche de la figure, cette zone centrale 6 présente une section verticale rectiligne, de sorte qu'elle est développable. As can be seen on the left of the figure, this central zone 6 has a rectilinear vertical section, so that it is developable.
En d'autres termes, la zone centrale du bouclier a la forme d'une bande incurvée dont la concavité est tournée vers l'arrière du véhicule. In other words, the central zone of the shield has the shape of a curved strip, the concavity of which faces the rear of the vehicle.
La zone centrale reçoit un film 9 de revêtement du type SOLVANT CAST ou coextrudé ou PLAXAGE. Ce film 9 peut être facilement surmoulé sur la pièce du fait que ladite zone centrale 6 présente une forme développable. Le film peut en effet s'adapter à la forme du moule d'injection du bouclier 3 sans s'étirer ni se déchirer. The central zone receives a coating film 9 of the SOLVENT CAST or coextruded or PLAXING type. This film 9 can be easily molded onto the part because said central zone 6 has a developable shape. The film can indeed adapt to the shape of the injection mold of the shield 3 without stretching or tearing.
Le film 9 est découpé et appliqué dans le moule d'injection du bouclier de manière telle que la périphérie 10 du film demeure en retrait des bords 7 du bouclier et laisse subsister une bande 11 de matière plastique brute ou teintée dans la masse qui tranche entre la couleur de la peinture réalisée sur le capot 1 et la couleur du film. The film 9 is cut and applied in the injection mold of the shield so that the periphery 10 of the film remains set back from the edges 7 of the shield and leaves a strip 11 of raw or tinted plastic in the mass which cuts between the color of the paint produced on the cover 1 and the color of the film.
Les éventuels problèmes de concordance de couleur sont ainsi moins facilement décelables. Any problems with color matching are therefore less easily detected.
L'exemple fourni ci-dessus ne constitue en rien une limitation de la portée de l'invention, laquelle est définie par les revendications annexées. The example provided above in no way constitutes a limitation on the scope of the invention, which is defined by the appended claims.
En particulier, il est clair que l'invention concerne aussi bien des pièces avant que des pièces arrière du véhicule, notamment son bouclier arrière.In particular, it is clear that the invention relates to both front parts and rear parts of the vehicle, in particular its rear bumper.
