IV-IV of Figure 3; Figures 5 and 6 are cross sections along lines VV and VI-VI of Figure 2 respectively; FIG. 7 schematically represents the method of mounting the spoiler on the body.

Le spoiler illustré est formé d'un corps creux et comprend une première partie de fixation, désignée dans son ensemble par la référence i, apte à en permettre l'assemblage à la carrosserie d'un véhicule automobile, ayant sensiblement la forme d'une plaque triangulaire, et une seconde partie 2 définissant une enveloppe et ayant la forme d'une coupe.The spoiler illustrated is formed of a hollow body and comprises a first fixing part, designated as a whole by the reference i, capable of allowing its assembly to the body of a motor vehicle, having substantially the shape of a triangular plate, and a second part 2 defining an envelope and having the shape of a cup.

La première partie 1 comporte une plaque 3 dans laquelle est ménagée une rainure longitudinale 4 (figure 5) prévue pour être accouplée à une partie correspondante d'un longeron de la carrosserie; la plaque 3 est également munie de bords périphériques rectilignes 5, sensiblement orthogonaux à la plaque elle-même.The first part 1 comprises a plate 3 in which is formed a longitudinal groove 4 (FIG. 5) intended to be coupled to a corresponding part of a spar of the bodywork; the plate 3 is also provided with rectilinear peripheral edges 5, substantially orthogonal to the plate itself.

La seconde partie 2 comprend deux parois latérales 6a et une troisième paroi 6b; les parois latérales présentent sensiblement en section transversale la forme d'une demi-ellipse, comme le montre la coupe de la figure 5, et les dimensions des demi-axes de cette ellipse vont en décroissant d'une extrémité à l'autre de cette seconde partie, de façon à définir une enveloppe qui, vue du côté de la paroi -6b a un profil en demi-ellipse, du côté d'une paroi 6a le profil d'un triangle rectangle, et vue du dessus le profil d'un triangle isocèle; les bords rectilignes 7 de la partie 2 peuvent être assemblés par encastrement aux bords correspondants 5 de l'autre partie 1, comme on le voit clairement dans les coupes des figures 4 et 5.The second part 2 comprises two side walls 6a and a third wall 6b; the side walls have substantially in cross section the shape of a half-ellipse, as shown in the section of FIG. 5, and the dimensions of the half-axes of this ellipse decrease from one end to the other of this second part, so as to define an envelope which, seen from the side of the wall -6b has a profile in half-ellipse, on the side of a wall 6a the profile of a right triangle, and seen from above the profile of an isosceles triangle; the straight edges 7 of part 2 can be assembled by fitting to the corresponding edges 5 of the other part 1, as can be clearly seen in the sections of FIGS. 4 and 5.

Les deux parties comprennent des moyens permettant de les unir entre elles de façon à définir un corps creux unique. Ces moyens comprennent une ailette 8 faisant saillie à l'extrémité de plus faible dimension de la partie 2 et une cavité 9 ménagée dans l'extrémité correspondante de la partie 1; l'ailette 8 est adjacente à un renflement 11 pouvant se loger dans une perforation correspondante 10 de la partie 1.The two parts comprise means making it possible to join them together so as to define a single hollow body. These means include a fin 8 projecting from the smaller end of the part 2 and a cavity 9 formed in the corresponding end of the part 1; the fin 8 is adjacent to a bulge 11 which can be housed in a corresponding perforation 10 in part 1.

Les moyens d'assemblage comprennent en outre un appendice 12 faisant saillie sur la face inférieure de la plaque 3 (fig. 1) et muni d'une multiplicité de nervures de raidissage; cet appendice est apte à servir d'appui pour la seconde partie 2, comme on le voit clairement aux figures 4 et 5. Dans l'appendice 12 est ménagé un trou fileté 13 pour une vis 14 (fig. 5) qui traverse un trou corresppndant ménagé dans la seconde partie 2.Font également partie des moyens d'assemblage mentionnés plus haut un second appendice 18 (figure 4) obtenu par une conformation appropriée de la paroi de la plaque 3, ainsi qu'une ailette 19 apte à servir d'appui pour cet appendice; une vis 20 traversant un trou de l'appendice 18 et vissée dans un trou fileté correspondant de l'ailette peut bloquer la première sur la seconde; avantageusement, le trou fileté peut être ménagé dans un écrou 20a disposé au-dessous de l'ailette et solidarisé à celle-ci au moyen d'un élément de ressort-20b, comme on le voit clairement à la figure 4.The assembly means further comprise an appendage 12 projecting from the underside of the plate 3 (FIG. 1) and provided with a multiplicity of stiffening ribs; this appendage is capable of serving as a support for the second part 2, as can be clearly seen in FIGS. 4 and 5. In appendix 12 is provided a threaded hole 13 for a screw 14 (fig. 5) which passes through a hole corresppndant formed in the second part 2.Also part of the assembly means mentioned above a second appendage 18 (Figure 4) obtained by an appropriate conformation of the wall of the plate 3, as well as a fin 19 adapted to serve as support for this appendix; a screw 20 passing through a hole in the appendage 18 and screwed into a corresponding threaded hole in the fin can block the first on the second; advantageously, the threaded hole can be formed in a nut 20a placed below the fin and secured to it by means of a spring element-20b, as can be clearly seen in FIG. 4.

Le spoiler selon l'invention est muni en outre de moyens de fixation permettant son montage sur la carrosserie du véhicule.The spoiler according to the invention is further provided with fixing means allowing it to be mounted on the vehicle body.

Ceux-ci comprennent un bras 21 venu de matière avec la première partie en plaque 1 et muni d'un trou fileté 22, ainsi qu'une paire d'ailettes 23 et 25 munies de trous 24 et 26 (figure 3) et également venues de matière avec la première partie. Les deux parties 1 et 2 sont avantageusement réalisées en matière thermoplastique par des techniques de moulage par injection.These include an arm 21 integrally formed with the first plate portion 1 and provided with a threaded hole 22, as well as a pair of fins 23 and 25 provided with holes 24 and 26 (FIG. 3) and also provided of material with the first part. The two parts 1 and 2 are advantageously made of thermoplastic material by injection molding techniques.

L'assemblage des deux parties 1 et 2 constituant le spoiler s'effectue en insérant d'abord l'ailette 8 de la seconde partie d'enveloppe 2 dans la cavité correspondante 9 ménagée dans l'autre partie; puis, en faisant tourner les deux parties l'une par rapport à l'autre, sensiblement autour d'un axe passant par l'ailette 8 et la cavité 9 et parallèle au plan de la plaque 3, on met les deux parties au contact l'une de l'autre et on les accouple par les bords 5 et 7, comme on le voit aux figures 4 et 5. Enfin,.on bloque entre elles les deux parties en vissant les vis 14 et 20 dans leurs trous filetés respectifs.The assembly of the two parts 1 and 2 constituting the spoiler is carried out by first inserting the fin 8 of the second envelope part 2 in the corresponding cavity 9 formed in the other part; then, by rotating the two parts relative to each other, substantially around an axis passing through the fin 8 and the cavity 9 and parallel to the plane of the plate 3, the two parts are brought into contact one from the other and they are coupled by the edges 5 and 7, as can be seen in FIGS. 4 and 5. Finally,. we block the two parts between them by screwing the screws 14 and 20 in their respective threaded holes .

L'assemblage du spoiler à la carrosserie se fait selon le schéma de la figure 7; la première partie en plaque 1 s'appuie sur le longeron inférieur de la carrosserie 27, qui peut avoir avantageusement une forme telle qu'il s'insère dans la cavité 4 (figures 4 et 5) ménagée dans cette partie. Ensuite, on bloque le spoiler sur la carrosserie au moyen de vis insérées dans les trous 22, 24 et 26 du bras 21 et des ailettes 23 et 25 respectivement. Dans cette position, le plan médian du spoiler coïncide sensiblement avec celui de la roue 28, et le spoiler est en mesure de dévier le flux d'air qui frapperait normalement la roue, améliorant sensiblement la résistance aérodynamique du véhicule pendant la marche.The assembly of the spoiler to the body is done according to the diagram in Figure 7; the first plate part 1 is supported on the lower spar of the body 27, which may advantageously have a shape such that it fits into the cavity 4 (Figures 4 and 5) formed in this part. Then, the spoiler is blocked on the body by means of screws inserted in the holes 22, 24 and 26 of the arm 21 and the fins 23 and 25 respectively. In this position, the median plane of the spoiler substantially coincides with that of the wheel 28, and the spoiler is able to deflect the air flow which would normally strike the wheel, appreciably improving the aerodynamic resistance of the vehicle during walking.

On voit que la-structure du spoiler décrit est très simple et que les parties qui le constituent peuvent être fabriquées de façon simple et rapide en utilisant les techniques normales du moulage par injection. Le montage tant des parties entre elles que du spoiler sur la carrosserie est également très facile.It can be seen that the structure of the spoiler described is very simple and that the parts which constitute it can be produced in a simple and rapid manner using the normal techniques of injection molding. The assembly of both the parts together and of the spoiler on the body is also very easy.

Bien entendu, la structure décrite peut être modifiée sans sortir du cadre de l'invention. Of course, the structure described can be modified without departing from the scope of the invention.
