PAVILLON DE TOIT POUR VEHICULE EQUI PE DE BARRES  ROOF PAVILION FOR EQUIPPED VEHICLE OF BARS
LONGITUDINALES DE TOIT  LONGITUDINAL ROOF
La présente invention se rapporte à un pavillon de toit pour véhicule automobile. The present invention relates to a roof hatch for a motor vehicle.
Elle se rapporte plus particulièrement à un pavillon de toit équipé de barres longitudinales de toit.  It relates more particularly to a roof pavilion equipped with longitudinal roof bars.
Les figures 1 et 2 illustrent un pavillon de toit 9 connu comprenant : Figures 1 and 2 illustrate a known roof pavilion 9 comprising:
- un panneau 90 principal central pouvant être plein, c'est-à-dire réalisé entièrement en tôle, ou vitré, c'est-à-dire pourvu d'un vitrage, où ce panneaua central main panel 90 which can be solid, that is to say made entirely of sheet metal, or glazed, that is to say provided with a glazing, where this panel
90 présente deux bordures longitudinales 91 ; 90 has two longitudinal edges 91;
- deux arches supérieures 92 longitudinales s'étendant sur les côtés des éléments longitudinaux de bordure 91 , chaque arche supérieure 92 présentant une partie externe 93, autrement appelée côté d'habitacle, et une partie interne 94 recouverte par ladite partie externe 93, une telle partie interne 94 comprenant une doublure d'arche 94a et un renfort d'arche 94b soudés l'un à l'autre pour définir une pièce creuse ;  - two longitudinal upper arches 92 extending on the sides of the longitudinal edge members 91, each upper arch 92 having an outer portion 93, otherwise called cockpit side, and an inner portion 94 covered by said outer portion 93, such inner portion 94 comprising an arch liner 94a and an arch brace 94b welded to each other to define a hollow piece;
- deux supports longitudinaux 95 du panneau 90 fixés sur une face interne du panneau 90, s'étendant en-dessous des éléments longitudinaux de bordure 91 , et assemblés sur les parties internes 94 respectives des arches supérieures 92 ; et  two longitudinal supports 95 of the panel 90 fixed on an inner face of the panel 90, extending below the longitudinal edge members 91, and assembled on the inner portions 94 of the respective upper arches 92; and
- deux barres longitudinales 96 de toit fixées sur les parties internes 94 respectives des arches supérieures 92 au moyen de vis de fixation 97 traversant des premiers orifices ménagés dans une feuillure supérieure 94c de jonction entre la doublure d'arche 94a et le renfort d'arche 94b.  two longitudinal roof bars 96 fastened to the respective inner portions 94 of the upper arches 92 by means of fixing screws 97 passing through first orifices formed in an upper rabbet 94c joining the arch lining 94a and the arch reinforcement 94b.
Comme visible sur la figure 2, des entretoises 98 sont intercalées entre les barres longitudinales 96 et des écrous 99 vissés sur les extrémités des vis de fixation 97 et coopérant avec les barres longitudinales 96, de sorte que les écrous 99 serrent les barres longitudinales 96 contre les entretoises 98. Le panneau 90 vient sensiblement en arasement des barres longitudinales 96.  As can be seen in FIG. 2, spacers 98 are interposed between the longitudinal bars 96 and nuts 99 screwed onto the ends of the fixing screws 97 and cooperating with the longitudinal bars 96, so that the nuts 99 tighten the longitudinal bars 96 against the struts 98. The panel 90 is substantially flush with the longitudinal bars 96.
Une telle structure soulève cependant de nombreuses difficultés liés aux assemblages par la technique de soudo-brasage laser et à la technique d'assemblage et de mise au point du procédé d'assemblage laser et du montage des barres longitudinales de toit. Ces difficultés ont pour cause principale les variations géométriques entre l'implantation d'un panneau plein (pavillon de toit normal) et d'un panneau vitré (pavillon de toit panoramique), car pour un même modèle de véhicule il est classique de monter l'un ou l'autre des panneaux de pavillon. Such a structure, however, raises many difficulties related to assemblies by the laser braze welding technique and the assembly technique and development of the laser assembly process and the mounting of longitudinal roof bars. These difficulties are mainly due to the geometric variations between the installation of a solid panel (normal roof pavilion) and a glazed panel (panoramic roof pavilion), because for the same model of vehicle it is conventional to mount one or other of the roof panels.
Actuellement, pour répondre à cette problématique d'implantation d'un panneau plein ou vitré sur un même modèle de véhicule, il est connu d'employer deux techniques distinctes de soudage suivant le choix du panneau : pour un panneau plein on utilise une solution de soudage laser dite par soudo-brasage, tandis que pour un panneau vitré on utilise une solution de soudage laser dite pas transparence.  Currently, to answer this problem of implantation of a solid or glazed panel on the same model of vehicle, it is known to use two distinct techniques of welding according to the choice of the panel: for a solid panel one uses a solution of soldering laser welding, while for a glazed panel is used a laser welding solution called not transparency.
L'emploi de deux techniques de soudage, suivant le choix du panneau de pavillon, complexifie ainsi le procédé de montage et implique un surcoût car nécessite sur la ligne d'assemblage (dite ligne de ferrage) la présence de deux outils adaptés à chacune des deux techniques.  The use of two welding techniques, depending on the choice of the roof panel, thus complicates the assembly process and involves an additional cost because requires on the assembly line (so-called forging line) the presence of two tools adapted to each of the two techniques.
En outre, cette structure actuelle de pavillon multiplie la diversité des pièces car elle impose également d'avoir des barres longitudinales de toit adaptées aux panneaux pleins (pavillon de toit normal) et des barres longitudinales de toit adaptées aux panneaux vitrés (pavillon de toit panoramique).  In addition, this current pavilion structure multiplies the diversity of rooms because it also requires having longitudinal roof bars adapted to solid panels (normal roof pavilion) and longitudinal roof bars adapted to glazed panels (panoramic roof pavilion). ).
L'invention se propose de simplifier le montage du pavillon de toit, en proposant une structure de pavillon qui permette de limiter la diversité des pièces en étant aussi bien adaptée aux panneaux pleins et vitrés, et également d'employer une seule et même technique de soudage laser, en l'occurrence de soudage laser par soudo-brasage, que la panneau de pavillon soit plein ou vitré.  The invention proposes to simplify the mounting of the roof pavilion, by proposing a roof structure which makes it possible to limit the diversity of the pieces by being as well adapted to the solid and glazed panels, and also to use a single technique of laser welding, in this case welding laser welding, that the roof panel is full or glazed.
A cet effet, elle propose un pavillon de toit pour véhicule automobile, du type comprenant :  For this purpose, it proposes a roof lodge for a motor vehicle, of the type comprising:
- un panneau principal central ;  - a central main panel;
- deux éléments longitudinaux de bordure venant dans le prolongement du panneau et solidaires du panneau ;  - Two longitudinal edge elements coming in the extension of the panel and integral with the panel;
- deux arches supérieures longitudinales s'étendant sur les côtés des éléments longitudinaux de bordure, chaque arche supérieure présentant une partie externe et une partie interne recouverte par ladite partie externe ;  - two longitudinal upper arches extending on the sides of the longitudinal edge members, each upper arch having an outer portion and an inner portion covered by said outer portion;
- deux supports longitudinaux du panneau fixés sur une face interne du panneau central, s'étendant en-dessous des éléments longitudinaux de bordure, et assemblés sur les parties internes respectives des arches supérieures ; et - deux barres longitudinales de toit fixées sur les parties internes respectives des arches supérieures au moyen d'organes de fixation traversant des premiers orifices ménagés dans lesdites parties internes des arches supérieures ; two longitudinal supports of the panel fixed on an inner face of the central panel, extending below the longitudinal edge elements, and assembled on the respective internal parts of the upper arches; and - Two longitudinal roof bars fixed on the respective inner portions of the upper arches by means of fasteners passing through first orifices formed in said inner portions of the upper arches;
où le pavillon de toit conforme à l'invention est remarquable en ce que : where the roof flag according to the invention is remarkable in that:
- les éléments longitudinaux de bordure recouvrent les premiers orifices ménagés dans les parties internes des arches supérieures et présentent des deuxièmes orifices de passage des organes de fixation au droit desdits premiers orifices, lesdits éléments longitudinaux de bordure étant fixés sur les parties externes respectives des arches supérieures ;  the longitudinal edge elements cover the first orifices formed in the internal parts of the upper arches and have second orifices for the passage of the fastening members in line with the said first orifices, the said longitudinal edge elements being fixed on the respective external parts of the upper arches; ;
- le pavillon comprend en outre des pièces intermédiaires de support des barres longitudinales de toit, lesdites pièces intermédiaires de support étant intercalées entre les éléments longitudinaux de bordure et les parties internes des arches supérieures et présentant des troisièmes orifices de passage des organes de fixation au droit des premiers et deuxièmes orifices ; et  - The flag further comprises intermediate pieces for supporting longitudinal roof bars, said intermediate support pieces being interposed between the longitudinal edge members and the inner portions of the upper arches and having third holes for the passage of the fasteners to the right first and second orifices; and
- les organes de fixation traversent lesdits premiers, deuxièmes et troisièmes orifices pour coopérer avec des organes complémentaires de fixation raccordés aux barres longitudinales de toit, lesdits organes complémentaires de fixation serrant les barres longitudinales de toit contre les éléments longitudinaux de bordure et serrant les pièces intermédiaires de support entre les éléments longitudinaux de bordure et les parties internes des arches supérieures.  the fasteners pass through said first, second and third orifices to cooperate with complementary fastening members connected to the longitudinal roof bars, said complementary fastening members clamping the longitudinal roof bars against the longitudinal edge members and clamping the intermediate pieces. support between the longitudinal edge members and the inner portions of the upper arches.
Ainsi, la structure du pavillon conforme à l'invention permet de supporter les barres longitudinales de toit avec les pièces intermédiaires de support ; ces pièces intermédiaires de support pouvant se déformer lors du serrage des barres longitudinales de toit contre les éléments longitudinaux de bordure, permettant aux éléments longitudinaux de bordure d'épouser au plus près les parties externes des arches supérieures.  Thus, the structure of the roof according to the invention can support the longitudinal roof bars with the intermediate support parts; these intermediate support pieces can be deformed during the tightening of longitudinal roof bars against the longitudinal edge elements, allowing the longitudinal edge elements to marry closer to the outer parts of the upper arches.
De plus, cette structure permet un soudage des éléments longitudinaux de bordure sur les parties externes des arches supérieures par une seule et même technique, comme par exemple et de préférence le soudage laser par soudo-brasage, que l'on choisisse un panneau plein ou vitré.  In addition, this structure allows a welding of the longitudinal edge elements on the outer parts of the upper arches by one and the same technique, such as for example and preferably soldering laser welding, whether one chooses a solid panel or window.
Pour un panneau plein, les éléments longitudinaux de bordure peuvent faire partie intégrante du panneau en tôle et sont donc adaptés pour le soudo-brasage. Pour un panneau vitré, les éléments longitudinaux de bordure peuvent constituer des éléments en tôle solidaires du vitrage et donc adaptés pour le soudo-brasage. For a solid panel, the longitudinal edge elements can be an integral part of the sheet metal panel and are therefore suitable for brazing. For a glazed panel, the longitudinal edge elements can constitute sheet metal elements integral with the glazing and therefore suitable for the braze-soldering.
Ces pièces intermédiaires de support assurent donc le rattrapage du jeu nécessaire pour le soudo-brasage par déformation lors de l'application du couple de serrage, d'où un gain économique de la fonction rattrapage de jeu.  These intermediate support parts thus ensure the clearance necessary clearance for the braze-deformation brazing when applying the tightening torque, resulting in an economic gain of the catch-up function.
Avantageusement, chaque pièce intermédiaire de support est montée dans un orifice ménagé dans le support longitudinal correspondant, où ladite pièce intermédiaire de support comporte une butée supérieure et une butée inférieure décalées l'une de l'autre en hauteur et autorisant un débattement vertical de ladite pièce intermédiaire de support dans ledit orifice entre les deux dites butées.  Advantageously, each intermediate support piece is mounted in an orifice formed in the corresponding longitudinal support, wherein said intermediate support piece comprises an upper stop and a lower stop offset from each other in height and allowing a vertical deflection of said intermediate support piece in said hole between the two said stops.
Ce débattement vertical, bloqué en haut et en bas par les butées respectivement supérieure et inférieure, permet de réaliser un jeu de montage et de serrage des barres longitudinales de toit. Ce jeu permet aussi d'accepter plusieurs galbes de panneau de pavillon ainsi qu'une disposition des pièces intermédiaires de support sur toute la longueur du pavillon, permettant ainsi d'employer des pièces intermédiaires de support indentiques pour la fixation des mêmes barres longitudinales de toit.  This vertical deflection, blocked up and down by the respectively upper and lower stops, allows for a set of mounting and clamping longitudinal roof bars. This set also makes it possible to accept several roof panel curves as well as an arrangement of the intermediate support parts along the entire length of the roof, thus making it possible to use indirect intermediate support parts for fastening the same longitudinal roof bars. .
La conception de ces pièces intermédiaires de support permet une symétrie dans leurs utilisations, voire une utilisation pour le montage de barres longitudinales de toit sur d'autres modèles de véhicule si le jeu entre les butées supérieure et inférieure le permet.  The design of these intermediate support parts allows a symmetry in their uses, or even a use for mounting longitudinal roof bars on other vehicle models if the clearance between the upper and lower stops allows it.
Dans une réalisation particulière, chaque pièce intermédiaire de support présente :  In a particular embodiment, each intermediate support piece has:
- une première paroi sensiblement horizontale dans laquelle est ménagée le ou au moins un troisième orifice et venant en appui contre une face interne de l'élément longitudinal de bordure concerné ; et  - A first substantially horizontal wall in which is formed the or at least a third hole and bearing against an inner face of the longitudinal edge member concerned; and
- une seconde paroi sensiblement verticale montée dans l'orifice ménagé dans le support longitudinal correspondant, ledit orifice se présentant sous la forme d'une fente longitudinale, où les butées supérieure et inférieure font saillie de ladite seconde paroi.  a second substantially vertical wall mounted in the orifice formed in the corresponding longitudinal support, said orifice being in the form of a longitudinal slot, where the upper and lower stops protrude from said second wall.
Cette forme en « L » des pièces intermédiaires de support permet avantageusement une symétrie dans leurs utilisations, à droite et à gauche, tout en remplissant à la fonction de support de l'élément longitudinal de bordure concerné et de réglage du jeu grâce aux butées supérieure et inférieure. This "L" shape of the intermediate support pieces advantageously allows a symmetry in their uses, on the right and on the left, while filling the support function of the longitudinal element of relevant border and game adjustment through the upper and lower stops.
Selon une caractéristique, chaque fente longitudinale présente une zone élargie prolongée par au moins une zone amincie, afin de permettre l'insertion de la pièce intermédiaire de support correspondante dans la zone élargie de la fente longitudinale puis le coulissement longitudinal de ladite pièce intermédiaire de support pour engager celle-ci au moins partiellement dans la zone amincie de ladite fente longitudinale, et dans lequel le pavillon comprend en outre des organes de blocage interdisant le retour complet des pièces intermédiaires de support dans les zones élargies des fentes longitudinales.  According to one characteristic, each longitudinal slot has a widened zone extended by at least one thinned zone, in order to allow the insertion of the corresponding intermediate support piece into the widened zone of the longitudinal slot and then the longitudinal sliding of said intermediate support piece. to engage the latter at least partially in the thinned area of said longitudinal slot, and wherein the flag further comprises locking members prohibiting the complete return of the intermediate support parts in the enlarged areas of the longitudinal slots.
Ainsi, les pièces intermédiaires de support sont montées dans les fentes longitudinales prévues dans les supports longitudinaux correspondants, au droit de chaque fixation des barres longitudinales de toit, de la manière suivante : on monte chaque pièce intermédiaire de support en position initiale dans la zone élargie de la fente longitudinale, puis on la fait coulisser en position finale dans la zone amincie apte à la retenir, et enfin un organe de blocage est ajouté après cette mise en position de façon à retenir la pièce intermédiaire de support dans sa position finale. En conséquence, le montage de chaque pièce intermédiaire de support se fait par une translation suivant la direction longitudinale du véhicule.  Thus, the intermediate support pieces are mounted in the longitudinal slots provided in the corresponding longitudinal supports, at the right of each fixing of the longitudinal roof bars, in the following manner: each intermediate support piece is mounted in the initial position in the enlarged area of the longitudinal slot, then it is slid into the end position in the thinned area adapted to retain it, and finally a locking member is added after this setting in position so as to retain the intermediate support piece in its final position. Consequently, the mounting of each intermediate support piece is done by a translation along the longitudinal direction of the vehicle.
Selon une autre caractéristique, chaque organe de blocage est réalisé sous la forme d'un organe d'encliquetage qui coopère avec la fente longitudinale concernée pour bloquer la pièce intermédiaire de support correspondante dans la zone amincie de ladite fente longitudinale.  According to another characteristic, each locking member is in the form of a latching member which cooperates with the longitudinal slot concerned to block the corresponding intermediate support member in the thinned zone of said longitudinal slot.
De manière avantageuse, chaque pièce intermédiaire de support présente au moins une ligne de faiblesse longitudinale, de préférence plusieurs lignes de faiblesse longitudinales.  Advantageously, each intermediate support piece has at least one longitudinal line of weakness, preferably several longitudinal lines of weakness.
Cette ou ces lignes de faiblesse longitudinales forment des amorces de déformation de la pièce intermédiaire de support, qui lui permettront de se déformer de manière contrôlée pour épouser la forme du panneau de pavillon lors du serrage de la barre longitudinale de toti concernée.  This or these longitudinal lines of weakness form deformation primers of the intermediate support piece, which will allow it to deform in a controlled manner to match the shape of the roof panel when tightening the longitudinal bar of toti concerned.
Par exemple, la ou les lignes de faiblesse longitudinales sont ménagées dans la première paroi, sensiblement horizontale, de la pièce intermédiaire de support.  For example, the longitudinal line or weaknesses are formed in the first substantially horizontal wall of the intermediate support piece.
Dans un mode de réalisation particulier, el pavillon comprend une pièce intermédiaire de support pour un ou deux organes de fixation des barres longitudinales de toit. Autrement dit, chaque pièce intermédiaire de support présente un ou deux troisièmes orifices. In a particular embodiment, the flag comprises an intermediate piece of support for one or two members for fixing the bars. longitudinal roof. In other words, each intermediate support piece has one or two third holes.

La doublure 32 et le renfort 33 présentent des bordures supérieures soudées l'une à l'autre pour former une feuillure supérieure 34 sensiblement horizontales. La feuillure supérieure 34 est soudée sur une bordure supérieure horizontale de la partie externe 30. Les feuillures supérieures 34 présentent des premiers orifices.  The liner 32 and the reinforcement 33 have upper edges welded to each other to form a substantially horizontal upper rebate 34. The upper rabbet 34 is welded to a horizontal upper edge of the outer portion 30. The upper rabbets 34 have first orifices.
La doublure 32 et le renfort 33 présentent également des bordures inférieures soudées l'une à l'autre pour former une feuillure inférieure 35. La feuillure inférieure 35 est soudée sur une bordure inférieure de la partie externe 30.  The liner 32 and the reinforcement 33 also have lower edges welded to each other to form a lower rabbet 35. The lower rabbet 35 is welded to a lower edge of the outer portion 30.
Les éléments longitudinaux de bordure 2a, 2b recouvrent les feuillures supérieures 34 respectives, ainsi que leurs premiers orifices, jusqu'à atteindre les parties externes 30 des arches supérieures 3. Les éléments longitudinaux de bordure 2a, 2b sont soudés sur les parties externes 30 des arches supérieures 3 par soudo-brasage. Les éléments longitudinaux de bordure 2a, 2b présentent des deuxièmes orifices au droit des premiers orifices ménagés dans les feuillures supérieures 34, autrement dit en regard de ces premiers orifices.  The longitudinal edge elements 2a, 2b cover the respective upper rebates 34, as well as their first orifices, until reaching the outer portions 30 of the upper arches 3. The longitudinal edge members 2a, 2b are welded to the outer portions 30 of the upper arches 3 by solder-brazing. The longitudinal edge elements 2a, 2b have second orifices in line with the first orifices formed in the upper rabbets 34, ie opposite these first orifices.
Le pavillon de toit comporte aussi deux supports longitudinaux 4 du panneau 1 a, 1 b fixés sur une face interne du panneau 1 a, 1 b et s'étendant en- dessous des éléments longitudinaux de bordure 2a, 2b. Chaque support longitudinal 4 présente une section transversale en marche d'escalier avec deux bordures sensiblement horizontales décalées en hauteur et une paroi centrale de liaison entre les deux bordures.  The roof pavilion also comprises two longitudinal supports 4 of the panel 1a, 1b fixed on an inner face of the panel 1a, 1b and extending below the longitudinal edge members 2a, 2b. Each longitudinal support 4 has a cross-sectional staircase with two substantially horizontal edges offset in height and a central connecting wall between the two borders.
Dans l'exemple des figures 3 et 5, les supports longitudinaux 4 sont fixés sur la face interne du panneau 1 a par des cordons de colle 20a.  In the example of Figures 3 and 5, the longitudinal supports 4 are fixed on the inner face of the panel 1a by adhesive beads 20a.
Dans l'exemple des figures 4 et 6, les supports longitudinaux 4 sont soudés sur les éléments longitudinaux de bordure 2b qui, pour rappel, sont fixées sur la face interne du panneau 1 b en verre avec des cordons de colle 20b.  In the example of Figures 4 and 6, the longitudinal supports 4 are welded to the longitudinal edge members 2b which, for recall, are fixed on the inner face of the glass panel 1b with adhesive beads 20b.
En outre, les supports longitudinaux 4 sont soudés sur les feuillures supérieures 34 des parties internes 31 respectives des arches supérieures 3.  In addition, the longitudinal supports 4 are welded to the upper rabbets 34 of the respective inner portions 31 of the upper arches 3.
Les supports longitudinaux 4 présentent des fentes longitudinales The longitudinal supports 4 have longitudinal slots
40 visible sur les figures 5, 6 et 10 présentant chacune une zone élargie prolongée par au moins une zone amincie, en l'occurrence par deux zones amincies situées de part et d'autre de la zone élargie. 40 visible in Figures 5, 6 and 10 each having an enlarged area extended by at least one thinned zone, in this case by two thinned zones located on either side of the enlarged zone.
Le pavillon de toit comporte de plus deux barres longitudinales 5 de toit fixées sur les feuillures supérieures 34 des arches supérieures 3 au moyen de vis de fixation 6 traversant les premiers orifices ménagés dans ces feuillures supérieures 34 et les deuxièmes orifices ménagés dans les éléments longitudinaux de bordure 2a, 2b.  The roof pavilion further comprises two longitudinal roof bars 5 fastened to the upper rabbets 34 of the upper arches 3 by means of fixing screws 6 passing through the first orifices formed in these upper rabbets 34 and the second orifices formed in the longitudinal elements of the roof. border 2a, 2b.
Les têtes des vis de fixation 6 viennent en appui contre les faces internes des feuillures supérieures 34, et les extrémités libres des vis de fixation 6 coopèrent par vissage avec des écrous 60 raccordés aux barres longitudinales de toit 5. Ainsi, les écrous 60 sont vissés sur les vis de fixation 6 pour serrer les barres longitudinales de toit 5 contre les éléments longitudinaux de bordure 2a, 2b.  The heads of the fixing screws 6 bear against the inner faces of the upper rabbets 34, and the free ends of the fixing screws 6 cooperate by screwing with nuts 60 connected to the longitudinal roof bars 5. Thus, the nuts 60 are screwed on the fixing screws 6 to tighten the longitudinal roof bars 5 against the longitudinal edge members 2a, 2b.
Le pavillon de toit comporte en supplément des pièces intermédiaires de support 7 des barres longitudinales de toit 5 qui sont montées intercalées entre les éléments longitudinaux de bordure 2a, 2b et les feuillures supérieures 34 des arches supérieures 3.  The roof pavilion additionally comprises intermediate support pieces 7 longitudinal roof bars 5 which are mounted interposed between the longitudinal edge elements 2a, 2b and the upper rebates 34 of the upper arches 3.
Chaque pièce intermédiaire de support 7 se présente sous la forme d'un profilé réalisé dans un matériau métallique, tel que de l'acier ou de l'aluminium. Par exemple, chaque pièce intermédiaire de support 7 peut être réalisée en aluminium extrudé.  Each intermediate support piece 7 is in the form of a profile made of a metallic material, such as steel or aluminum. For example, each intermediate support piece 7 may be made of extruded aluminum.
Chaque pièce intermédiaire de support 7 comporte une forme générale en « L » avec les deux parois à angle droit suivantes :  Each intermediate support piece 7 has a general shape in "L" with the two walls at right angles:
- une première paroi 71 sensiblement horizontale dans laquelle est ménagée au moins un troisième orifice 70, de préférence un ou deux troisièmes orifices a first substantially horizontal wall 71 in which is provided at least a third orifice 70, preferably one or two third orifices;
70, et venant en appui contre la face interne de l'élément longitudinal de bordure 2a, 2b concerné ; et 70, and bearing against the inner face of the longitudinal edge member 2a, 2b concerned; and
- une seconde paroi 72 sensiblement verticale montée dans l'une des fentes longitudinales 40 ménagées dans le support longitudinal 4 correspondant.  - A second substantially vertical wall 72 mounted in one of the longitudinal slots 40 formed in the corresponding longitudinal support 4.
La pièce intermédiaire de support 7 comporte une butée supérieure The intermediate support piece 7 has a top stop
73 et une butée inférieure 74 qui font saillie de la seconde paroi 72 de part et d'autre de ladite seconde paroi 72, autrement dit sur deux faces verticales opposées. Ces butées 73, 74 se présentent sous la forme d'ailettes sensiblement horizontales et décalées l'une de l'autre en hauteur afin d'autoriser un débattement vertical de la pièce intermédiaire de support 7 dans la fente longitudinale 40 concernée entre ces deux butées 73, 74 ; la butée supérieure 73 limitant le débattement vertical vers le bas et la butée inférieure 74 limitant le débattement vertical vers le haut. Chaque pièce intermédiaire de support 7 est ainsi libre en translation dans le sens de la hauteur, la translation étant bloquée entre les deux butées 73, 74. 73 and a lower stop 74 which project from the second wall 72 on either side of said second wall 72, in other words on two opposite vertical faces. These stops 73, 74 are in the form of substantially horizontal fins and offset from each other in height in order to allow a vertical clearance of the intermediate support piece 7 in the longitudinal slot 40 between these two stops 73, 74; stop upper 73 limiting the vertical travel downward and the lower stop 74 limiting the vertical travel upwards. Each intermediate support piece 7 is thus free in translation in the direction of the height, the translation being locked between the two stops 73, 74.
Ainsi, le jeu nécessaire pour le soudo-brasage est garanti, et en outre le jeu est respecté entre le panneau 1 a, 1 b et chaque pièce intermédiaire de support 7 pour assurer une protection anticorrosion lors du passage dans les bains de cataphorèse.  Thus, the clearance required for the brazing is guaranteed, and furthermore the clearance is respected between the panel 1a, 1b and each intermediate support piece 7 to provide corrosion protection during passage in the cataphoresis baths.
La ou les troisièmes orifices 70 ménagés dans chaque première paroi 71 d'une pièce intermédiaire de support 7 viennent au droit des premiers et deuxièmes orifices, pour permettre le passage des vis de fixation 6 à travers ces troisièmes orifices 70. Ainsi, les écrous 60 sont vissés sur les vis de fixation 6 pour serrer les pièces intermédiaires de support 7 entre les éléments longitudinaux de bordure 2a, 2b et les feuillures supérieures 34 des arches supérieures 3.  The third orifices 70 formed in each first wall 71 of an intermediate support part 7 come to the right of the first and second orifices, to allow the fastening screws 6 to pass through these third orifices 70. Thus, the nuts 60 are screwed onto the fastening screws 6 to tighten the intermediate support pieces 7 between the longitudinal edge elements 2a, 2b and the upper rebates 34 of the upper arches 3.
Lors de ces serrages, les pièces intermédiaires de support 7 se déforment et leurs déformations sont contrôlées au moyen de lignes de faiblesse longitudinales 75 ménagées dans les premières parois des pièces intermédiaires de support 7. Ces lignes de faiblesse longitudinales 75 se présentent sous la forme de lignes de moindre épaisseur.  During these tightenings, the intermediate support pieces 7 deform and their deformations are controlled by means of longitudinal lines of weakness 75 formed in the first walls of the intermediate support pieces 7. These longitudinal lines of weakness 75 are in the form of lines of lesser thickness.
Le montage d'une pièce intermédiaire de support 7 dans une fente longitudinale 40 se fait comme suit : d'abord on insère la seconde paroi 72 de la pièce intermédiaire de support 7 dans la zone élargie de la fente longitudinale 40, puis on fait coulisser longitudinalement la pièce intermédiaire de support 7 pour engager celle-ci au moins partiellement dans la zone amincie de la fente longitudinale 40 comme visible sur la figure 10.  The mounting of an intermediate support piece 7 in a longitudinal slot 40 is as follows: first the second wall 72 of the intermediate support piece 7 is inserted into the enlarged area of the longitudinal slot 40, and then sliding longitudinally the intermediate support piece 7 to engage it at least partially in the thinned zone of the longitudinal slot 40 as visible in FIG.
Pour bloquer chaque pièce intermédiaire de support 7 dans la zone amincie de la fente longitudinale 40 concernée, le pavillon comprend en outre des organes de blocage 8 montés dans les fentes longitudinales 40 pour interdire le retour complet des pièces intermédiaires de support 7 dans les zones élargies des fentes longitudinales 40.  To block each intermediate support piece 7 in the thinned zone of the longitudinal slot 40 concerned, the flag further comprises locking members 8 mounted in the longitudinal slots 40 to prevent the complete return of the intermediate support pieces 7 in the widened areas longitudinal slots 40.
Comme illustré sur les figures 5, 6 et 9, chaque organe de blocage 8 se présente sous la forme d'un organe d'encliquetage qui comprend une embase et deux pattes parallèles élastiquement déformables munies de crans externes et qui font saillie de ladite embase. Chaque organe d'encliquetage 8 est montée dans la zone élargie de la fente longitudinale 40 concernée, les pattes coopérant avec le pourtour de la fente longitudinale 40 pour se bloquer dans la zone élargie et ainsi bloquer la pièce intermédiaire de support 7 correspondante dans la zone amincie de ladite fente longitudinale 40. As illustrated in Figures 5, 6 and 9, each locking member 8 is in the form of a detent member which comprises a base and two parallel elastically deformable tabs provided with external notches and which project from said base. Each detent member 8 is mounted in the enlarged area of the longitudinal slot 40 in question. tabs cooperating with the periphery of the longitudinal slot 40 to lock in the enlarged area and thus block the corresponding intermediate support part 7 in the thinned area of said longitudinal slot 40.
Bien entendu l'exemple de mise en œuvre évoqué ci-dessus ne présente aucun caractère limitatif et d'autres améliorations et détails peuvent être apportés au pavillon de toit selon l'invention, sans pour autant sortir du cadre de l'invention où d'autres formes de pièce intermédiaire de support peuvent par exemple être réalisées.  Of course the implementation example mentioned above is not limiting and other improvements and details can be made to the roof of the invention, without departing from the scope of the invention where other forms of intermediate support piece may for example be made.
