VEHICULE AUTOMOBILE A CARROSSERIE RECOUVERTE PAR UN ENSEMBLE EXTÉRIEUR DE DÉCORATION ET DE PROTECTION MOTOR VEHICLE WITH BODY COVERED BY AN EXTERIOR DECORATION AND PROTECTION ASSEMBLY
DESCRIPTIONDESCRIPTION
DOMAINE TECHNIQUETECHNICAL AREA
La présente invention concerne un véhicule automobile dont la carrosserie est recouverte par un ensemble extérieur de décoration et de protection.The present invention relates to a motor vehicle whose body is covered by an outer set of decoration and protection.
Les véhicules automobiles sont appréciés et choisis par les utilisateurs, bien entendu, non seulement pour leurs très nombreuses caractéristiques techniques, pour leur confort de circulation, mais également en fonction de leur esthétique. La décoration donne des effets visuels qui s'avèrent agréable et attractifs pour l'utilisateur et pour son entourage. La décoration est donc un facteur important pour le choix d'un véhicule par un utilisateur. Une telle décoration constitue ainsi un argument commercial non négligeable.Motor vehicles are appreciated and chosen by users, of course, not only for their many technical characteristics, for their comfort of movement, but also for their aesthetics. The decoration gives visual effects that are pleasant and attractive for the user and those around him. Decoration is therefore an important factor for the choice of a vehicle by a user. Such decoration is thus a significant commercial argument.
Dans la description qui suit, le terme carrosserie est entendu dans son interprétation la plus large comme étant une enveloppe d'un véhicule automobile, qui repose en général sur le châssis et contient les personnes et/ou les charges à transporter. De ce fait, la carrosserie inclut par extension tous les ouvrants, tels que les portières, le capot avant, le hayon arrière, et d'autres pièces encore.In the following description, the term bodywork is understood in its broadest interpretation as being an envelope of a motor vehicle, which is generally based on the frame and contains the persons and / or loads to be transported. As a result, the body includes by extension all the doors, such as the doors, the front cover, the tailgate, and other parts.
L'ensemble extérieur de décoration et de protection est destinée à la fois à masquer le matériau constitutif, et à assurer simultanément la décoration et la protection supérieure de la carrosserie. L'ensemble extérieur doit être d'assez faible épaisseur, de grande qualité, durable, résistant aux agressions extérieures et peu coûteux. Cet ensemble extérieur doit en effet résister aux rayures, aux UV, aux basses températures, à l'humidité, aux solvants de nettoyage, et d'autres encore. Outre des décorations obtenues grâce à différents types de couleurs et de pigmentations, les efforts se sont portés sur la réalisation d'effets optiques particulièrement attractifs au niveau de la surface extérieure de la carrosserie et de son ensemble supérieur de décoration et de protection. Cette décoration subit les influences de la mode aussi bien dans le choix des couleurs que dans l'utilisation des dernières évolutions technologiques en termes de matériaux de décoration. Des peintures comportant des pigments générateurs d'effets irisés ou métallisés sont apparues sur le marché. Ces effets donnent de la richesse visuelle et une attractivité à la carrosserie et au véhicule obtenu. Les constructeurs proposent différentes couleurs pour leurs modèles de véhicules dans les catalogues. De plus, certaines de ces colorations sont disponibles en une teinte mate et d'autres colorations sont proposées en une teinte brillante. Des motifs décoratifs plus complexes sont également appréciés par les utilisateurs.The exterior decoration and protection assembly is intended both to mask the constituent material, and simultaneously ensure the decoration and the upper protection of the body. The outer assembly must be of low thickness, high quality, durable, resistant to external aggression and inexpensive. This outdoor set must indeed withstand scratches, UV, low temperatures, humidity, cleaning solvents, and more. In addition to decorations obtained through different types of colors and pigments, efforts have been made to achieve particularly attractive optical effects on the exterior surface of the body and its upper decoration and protection assembly. This decoration is influenced by fashion as much in the choice of colors as in the use of the latest technological developments in terms of decorative materials. Paints with pigments generating iridescent or metallic effects have appeared on the market. These effects give visual richness and attractiveness to the body and the vehicle obtained. Manufacturers offer different colors for their vehicle models in the catalogs. In addition, some of these colors are available in a matte shade and other colors are offered in a brilliant shade. More complex decorative patterns are also appreciated by users.
ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART
Habituellement, une peinture de carrosserie comporte une première couche pouvant varier du blanc au gris foncé. Cette première couche est appelée couche primaire ou apprêt. La peinture comporte ensuite une deuxième couche appelée base colorée. Enfin, la finition est effectuée par une couche de vernis assurant un effet de brillance à la peinture.Usually, a body paint has a first layer that can vary from white to dark gray. This first layer is called primary layer or primer. The painting then comprises a second layer called a colored base. Finally, the finish is performed by a layer of varnish ensuring a gloss effect to the paint.
D'habitude le motif est dessiné par une deuxième couche de peinture ou bien des films de couleur différentes appliqués directement par-dessus la couche primaire de peinture appliquée sur la carrosserie. Le vernis vient terminer la finition.Usually the pattern is drawn by a second coat of paint or different colored films applied directly over the primary coat of paint applied to the body. The varnish finishes the finish.
Un des inconvénients de ce type de réalisation d'une peinture de carrosserie réside dans le fait que la surface de la peinture est alors irrégulière et présente des lignes de démarcation entre les différentes couleurs. La peinture s'avère ainsi inesthétique et confère une mauvaise image en termes de qualité perçue par l'utilisateur. De plus, avec la présence de films, le revêtement appliqué sur la carrosserie selon ce type de réalisation peut être plus fragile et risque de se détériorer. EXPOSE DE L'INVENTIONOne of the drawbacks of this type of realization of a bodywork paint lies in the fact that the surface of the paint is then irregular and has demarcation lines between the different colors. The painting thus proves unsightly and confers a bad image in terms of quality perceived by the user. In addition, with the presence of films, the coating applied to the bodywork according to this type of embodiment may be more fragile and may deteriorate. SUMMARY OF THE INVENTION
Un problème principal que se propose de résoudre l'invention consiste à mettre au point un véhicule muni d'une carrosserie recouverte par un ensemble extérieur de décoration et de protection. Un deuxième problème est d'optimiser la peinture de la carrosserie d'un véhicule en faisant apparaître un motif sur cette même carrosserie, grâce à l'ensemble extérieur. Un troisième problème est d'éviter des variations d'épaisseurs de l'ensemble extérieur pouvant survenir à la surface d'une carrosserie. Un autre problème encore consiste à prévoir une décoration qui reste identique à celle prévue initialement par le constructeur.A main problem to be solved by the invention is to develop a vehicle with a body covered by an outer set of decoration and protection. A second problem is to optimize the painting of the bodywork of a vehicle by showing a pattern on the same bodywork, thanks to the exterior assembly. A third problem is to avoid variations in the thickness of the outer assembly that can occur on the surface of a body. Another problem is to provide a decoration which remains identical to that initially provided by the manufacturer.
L'invention concerne donc un véhicule automobile, possédant une carrosserie dont une surface externe est recouverte par un ensemble extérieur de décoration et de protection, du type comprenant, successivement à partir de la surface externe de l'intérieur vers l'extérieur, une couche primaire, une couche intermédiaire d'une matière colorée et une couche supérieure d'un vernis.The invention therefore relates to a motor vehicle, having a body whose outer surface is covered by an outer decoration and protection assembly, of the type comprising, successively from the outer surface of the interior to the outside, a layer primary, an intermediate layer of a colored material and a top layer of a varnish.
Conformément à un aspect de la présente invention, le véhicule automobile est caractérisé en ce que l'ensemble extérieur de décoration et de protection comprend une couche supplémentaire, présentant un motif prédéterminé et intercalée entre la couche primaire et la couche intermédiaire de matière colorée.According to one aspect of the present invention, the motor vehicle is characterized in that the outer decoration and protection assembly comprises an additional layer, having a predetermined pattern and interposed between the primary layer and the intermediate layer of colored material.
Autrement dit, le motif est crée grâce à une couche supplémentaire rajoutée à la surface de la couche primaire sur laquelle vient se superposer la ou les colorations. Deux couches colorées sont combinées au sein du décor, à savoir une couche intermédiaire incorporant des pigments, et une autre couche supplémentaire disposée sous cette couche intermédiaire, permettant d'en faire ressortir les effets. Le contraste est crée par l'intermédiaire des couches de peinture de fond qui sont en contact direct avec la couche primaire, et non des couches supérieures. La surface de la peinture obtenue est régulière et la finition s'avère esthétique.In other words, the pattern is created by an additional layer added to the surface of the primary layer on which is superimposed the coloring. Two color layers are combined within the decoration, namely an intermediate layer incorporating pigments, and another additional layer disposed under this intermediate layer, to bring out the effects. Contrast is created through layers of background paint that are in direct contact with the primary layer, not upper layers. The surface of the paint obtained is regular and the finish is aesthetic.
L'ensemble extérieur de décoration et de protection obtenue selon l'invention est lisse et aucune surépaisseur n'est générée. Les couleurs employées le cas échéant dans la couche intermédiaire ne présentent entres-elles aucune démarcation visible. Les couches utilisées restent liées entres-elles. Il n'y a ainsi pas de risques de détérioration et de décollement du décor.The exterior decoration and protection assembly obtained according to the invention is smooth and no extra thickness is generated. The colors used where appropriate in the intermediate layer do not have any visible demarcation. The used layers remain intertwined. There is no risk of deterioration and detachment of the decor.
De manière particulièrement favorable, la couche primaire peut posséder une coloration gris clair ou blanche. La couche présentant le motif prédéterminé peut avantageusement posséder une coloration plus foncée que celle de la couche primaire.In a particularly favorable manner, the primary layer may have a light gray or white coloring. The layer having the predetermined pattern may advantageously have a darker coloration than that of the primary layer.
Préférentiellement, la couche présentant le motif prédéterminé peut recouvrir une fraction seulement de la surface de la couche primaire, de manière à former le motif prédéterminé. La couche intermédiaire de matière colorée peut favorablement être transparente ou translucide, de préférence légèrement transparente.Preferentially, the layer having the predetermined pattern may cover only a fraction of the surface of the primary layer, so as to form the predetermined pattern. The intermediate layer of colored material may favorably be transparent or translucent, preferably slightly transparent.
La couche intermédiaire de matière colorée peut comprendre des pigments. Les pigments peuvent être choisis seuls ou en mélange dans le groupe comprenant des particules de nacre, de l'alumine, des pigments organiques ou d'autres encore.The intermediate layer of colored material may comprise pigments. The pigments may be chosen alone or as a mixture from the group comprising mother-of-pearl particles, alumina, organic pigments or others.
BRÈVE DESCRIPTION DES DESSINSBRIEF DESCRIPTION OF THE DRAWINGS
L'invention sera bien comprise et ses divers avantages et différentes caractéristiques ressortiront mieux lors de la description suivante, de l'exemple non limitatif de réalisation, en référence aux dessins schématiques annexés, dans lesquels : la Figure 1 représente une vue latérale d'un véhicule automobile avec sa carrosserie ; et la Figure 2 représente une vue en coupe de la carrosserie recouverte par un ensemble extérieur de décoration et de protection selon l'invention.The invention will be better understood and its various advantages and different characteristics will become more apparent in the following description, of the non-limiting example of embodiment, with reference to the appended diagrammatic drawings, in which: FIG. 1 represents a side view of a motor vehicle with its bodywork; and Figure 2 shows a sectional view of the bodywork covered by an outer decoration and protection assembly according to the invention.
EXPOSE DETAILLE DE MODES DE REALISATION PREFERESDETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Comme l'illustre la Figure 1, un véhicule automobile (1) comprend une carrosserie (2), un pare-brise avant (3), une lunette arrière (4). La carrosserie (2) est formée par plusieurs éléments constitutifs, dont les principaux sont : un pavillon supérieur (6), un capot avant (7), un hayon arrière (8), une ou deux portières latérales (9), une aile latérale avant (11) et une aile latérale arrière (12). Le plus souvent, la carrosserie (2) est réalisée en acier.As illustrated in Figure 1, a motor vehicle (1) comprises a body (2), a front windshield (3), a rear window (4). The body (2) is formed by a plurality of constituent elements, the main ones of which are: an upper roof (6), a front hood (7), a tailgate (8), one or two side doors (9), a front lateral wing (11) and a rear lateral wing (12). Most often, the body (2) is made of steel.
Lors de son processus de fabrication, la carrosserie (2) est recouverte par un ensemble extérieur de décoration et de protection (13) revêtant tout ou partie de sa surface extérieure apparente (16).During its manufacturing process, the body (2) is covered by an exterior decoration and protection assembly (13) covering all or part of its apparent outer surface (16).
Cet ensemble (13) comprend une première couche primaire (14) formée par une première couche de peinture gris clair ou blanche. La première couche primaire (14) est posée directement contre la surface extérieure (16) de la carrosserie (2). Le choix de la teinte de la première couche primaire (14) dépend de la luminescence souhaitée pour la totalité de la décoration.This assembly (13) comprises a first primary layer (14) formed by a first layer of light gray or white paint. The first primary layer (14) is placed directly against the outer surface (16) of the body (2). The choice of the shade of the first primary layer (14) depends on the desired luminescence for the entire decoration.
Selon l'invention, un décor est crée en ajoutant une deuxième couche primaire (17), plus foncée, selon un dessin ou un motif prédéterminé. La deuxième couche primaire (17) est plaquée contre la première couche primaire (14). En variante, le dépôt de la deuxième couche primaire (17) peut être effectué sur une fraction seulement de la surface de la première couche primaire (14) et ainsi de la carrosserie (2). De tels motifs peuvent être continus et s'étendre sur la majeure partie de la carrosserie (2). Ils peuvent également être limités à des superficies réduites, et adopter les formes, des figures, des contours, des linéaments, destinées à constituer des motifs.According to the invention, a decoration is created by adding a second darker primary layer (17) according to a predetermined pattern or pattern. The second primary layer (17) is pressed against the first primary layer (14). As a variant, the deposition of the second primary layer (17) can be carried out on only a fraction of the surface of the first primary layer (14) and thus of the bodywork (2). Such patterns can be continuous and extend over most of the body (2). They can also be limited to reduced areas, and adopt shapes, figures, outlines, lineaments, intended to constitute patterns.
Ensuite, une base colorée (18) est appliquée sur la deuxième couche primaire (16). La base colorée (18) est ici une couche légèrement transparente. Elle comporte des pigments permettant de donner un effet esthétique particulier : particules de nacre, alumine, pigments organiques, etc., ou d'autres formes de pigments présentant des propriétés analogues. Ces pigments peuvent être minéraux ou organiques, de par leur composition spécifique ils sont disponibles en plusieurs variations de teintes. Ainsi, comme la base colorée (18) est légèrement transparente, elle va faire apparaître le contraste entre les parties claires et foncées situées dessous et faire ressortir le motif de la deuxième couche primaire (17). L'épaisseur de la base colorée (18) dépend de sa teinte.Then, a colored base (18) is applied to the second primary layer (16). The colored base (18) is here a slightly transparent layer. It contains pigments to give a particular aesthetic effect: mother-of-pearl particles, alumina, organic pigments, etc., or other forms of pigments with similar properties. These pigments can be mineral or organic, by their specific composition they are available in several variations of hues. Thus, since the colored base (18) is slightly transparent, it will reveal the contrast between the light and dark parts below and bring out the pattern of the second primary layer (17). The thickness of the colored base (18) depends on its hue.
De la sorte, les motifs ainsi réalisés par la deuxième couche primaire (17), ressortent de façon plus marquée, puisque leur couleur et leur aspect sont modifiés. La deuxième couche primaire (17) sert de zone de contraste. La deuxième couche primaire (17) constitue un fond coloré variable, dont la couleur se combine avec l'action des pigments pour moduler la couleur visible depuis l'extérieur de la carrosserie (2). Pour assurer la finition et la résistance, une couche finale de vernis de protection (19) est appliquée.In this way, the patterns thus produced by the second primary layer (17) emerge more markedly, since their color and their appearance are modified. The second primary layer (17) serves as a contrast zone. The second primary layer (17) is a variable colored background, the color of which combines with the action of the pigments to modulate the visible color from outside the body (2). To ensure the finish and strength, a final layer of protective varnish (19) is applied.
La présente invention n'est pas limitée aux modes de réalisation décrits et illustrés. De nombreuses modifications peuvent être réalisées, sans pour autant sortir du cadre défini par la portée du jeu de revendications. The present invention is not limited to the embodiments described and illustrated. Many modifications can be made, without departing from the scope defined by the scope of the set of claims.
