Description

"Système d'essu ie-glace com portant des moyens de fixation par bride d'un support moteur sur une traverse tubulaire" "Ie-ice wiping system comprising means for flange mounting of an engine support on a tubular cross member"
La présente invention concerne un système d'essuyage pour une vitre de véhicule automobile.The present invention relates to a wiping system for a motor vehicle window.
L'invention concerne plus particulièrement un système d'essuie- glace comportant une traverse tubulaire de structure, destinée à être fixée sur la caisse du véhicule, et un boîtier, notamment un boîtier d'un moteur ou d'un ensemble motoréducteur, comportant un support pour sa fixation sur la traverse.The invention relates more particularly to a windscreen wiper system comprising a tubular structural cross member, intended to be fixed to the vehicle body, and a housing, in particular a housing of an engine or of a geared motor assembly, comprising a support for its fixing on the crosspiece.
Selon une première conception grandement répandue, et dans la mesure où la nature des matériaux le permet, la fixation du support sur la traverse tubulaire se fait par soudage.According to a first widely used design, and insofar as the nature of the materials allows, the support is fixed to the tubular cross member by welding.
I l est aussi connu de réaliser la traverse tubulaire en deux parties, chacune des deux parties étant emmanchée sur ou dans un manchon correspondant appartenant au support. Cette conception a pour inconvénient de devoir réaliser la traverse tubulaire en au moins deux parties préalablement aux opérations d'assemblage. De plus, la fixation par emmanchement, complétée éventuellement par un sertissage, un collage ou un soudage, la rend définitive et ne permet pas un démontage simple du support.I t is also known to produce the tubular crosspiece in two parts, each of the two parts being fitted on or in a corresponding sleeve belonging to the support. This design has the disadvantage of having to make the tubular crosspiece in at least two parts before the assembly operations. In addition, fitting by fitting, possibly supplemented by crimping, bonding or welding, makes it final and does not allow simple disassembly of the support.
On a aussi proposé que la traverse tubulaire comporte un tronçon de fixation qui est aplati préalablement et sur lequel est fixé le support du moteur. Cette conception nécessite donc d'effectuer un écrasement local important de la traverse tubulaire qu'il est difficile d'obtenir avec précision et qui a pour inconvénient de présenter des risques de déformation globale de la traverse tubulaire, et notamment de l'orientation et de la position de ses extrémités opposées qui portent en général les paliers de guidage des arbres d'entraînement des essuie- glaces et/ou des moyens pour la fixation de la traverse sur la caisse du véhicule. De plus, une fois le tronçon aplati réalisé, la traverse tubulaire ne peut être utilisée que pour un véhicule particulier, sauf à réaliser plusieurs tronçons aplatis sur une même traverse en vue de permettre le montage du support dans différentes positions, cette dernière solution ayant pour inconvénient de multiplier les problèmes évoqués précédemment.It has also been proposed that the tubular cross member comprises a fixing section which is flattened beforehand and on which the motor support is fixed. This design therefore requires carrying out a significant local crushing of the tubular cross member which is difficult to obtain with precision and which has the drawback of presenting risks of overall deformation of the tubular cross member, and in particular of the orientation and the position of its opposite ends which generally carry the guide bearings of the drive shafts of the wipers and / or of the means for fixing the crossmember to the vehicle body. In addition, once the flattened section has been made, the tubular cross-member can only be used for a private vehicle, except for making several flattened sections on the same cross-member in order to allow the mounting of the support in different positions, the latter solution having the disadvantage of multiplying the problems mentioned above.
On a proposé dans le document EP-A-0.430.375 un système d'essuie-glace dans lequel le support du moteur comporte une partie de logement inférieure de forme générale semi-cylindrique concave complémentaire du profil de la traverse et dans laquelle est reçue au moins une partie inférieure d'un tronçon de fixation de la traverse, du type comportant des moyens pour immobiliser la traverse longitudinalement et en rotation autour de son axe par rapport au support, et du type comportant des moyens de fixation du tronçon de fixation de la traverse tubulaire dans la partie de logement inférieure du support qui comportent au moins un ensemble de serrage, notamment du type vis-écrou , dont l'axe de serrage est sensiblement orthogonal à l'axe longitudinal du tronçon de fixation de la traverse. Dans le mode de réalisation proposé dans ce document, le profil du tronçon de la traverse tubulaire qui est reçu dans la partie de logement inférieure est particulièrement complexe, c'est-à-dire qu'il n'est pas cylindrique circulaire mais présente une section sensiblement carrée de même que la partie de logement inférieure complémentaire. La tête de la vis de serrage coopère directement avec le bord d'un trou de passage formé dans la paroi de la traverse tubulaire, c'est-à-dire que la résistance à l'arrachement d'un tel assemblage est faible, le risque de déformation du trou de passage par la tête de la vis étant important. De plus, à la fin de l'opération de serrage, un épaulement de la vis doit provoquer un serrage de la partie inférieure de la paroi tubulaire dans le fond du logement, ce qui nécessite un dimensionnement précis du tronçon de fixation de la traverse tubulaire, dimensionnement qui est particulièrement délicat à obtenir compte tenu de la forme complexe du tronçon de fixation. Enfin , cette conception nécessite de faire appel à une vis de fixation qui n'est pas un composant standard.The document EP-A-0.430.375 has proposed a wiper system in which the motor support comprises a lower housing part of generally concave semi-cylindrical shape complementary to the profile of the cross member and in which is received at least one lower part of a fixing section of the cross-member, of the type comprising means for immobilizing the cross-member longitudinally and in rotation about its axis with respect to the support, and of the type comprising means of fixing the fixing section of the tubular cross member in the lower housing part of the support which comprise at least one clamping assembly, in particular of the screw-nut type, the clamping axis of which is substantially orthogonal to the longitudinal axis of the fixing section of the crosspiece. In the embodiment proposed in this document, the profile of the section of the tubular crosspiece which is received in the lower housing part is particularly complex, that is to say that it is not cylindrical circular but has a substantially square section as well as the complementary lower housing part. The head of the clamping screw cooperates directly with the edge of a through hole formed in the wall of the tubular cross member, that is to say that the tear resistance of such an assembly is low, the risk of deformation of the through hole by the head of the screw being significant. In addition, at the end of the tightening operation, a shoulder of the screw must cause a tightening of the lower part of the tubular wall in the bottom of the housing, which requires precise dimensioning of the fixing section of the tubular cross member. , sizing which is particularly difficult to obtain given the complex shape of the fixing section. Finally, this design requires the use of a fixing screw which is not a standard component.
Dans le document EP-A-0.484.1 75, le tronçon de fixation de la traverse tubulaire est de profil cylindrique circulaire, comme le reste du tube de traverse, mais pour sa fixation sans déformation dans la partie de logement inférieure, il est nécessaire de faire appel à un écrou de bridage interne de conception spéciale qui doit de plus être introduit préalablement dans le trou correspondant de la traverse, puis maintenu dans cette position jusqu'à l'opération de fixation au moyen de la vis. De plus, une telle conception nécessite d'agencer l'écrou de bridage interne dans un évidement formé dans le fond de la partie de logement inférieure formée dans le support.In document EP-A-0.484.1 75, the fixing section of the tubular cross-member is of circular cylindrical profile, like the rest of the cross-member tube, but for its fixing without deformation in the lower housing part, it is necessary to use a nut internal clamping of special design which must moreover be introduced beforehand in the corresponding hole of the cross member, then maintained in this position until the fixing operation by means of the screw. In addition, such a design requires arranging the internal clamping nut in a recess formed in the bottom of the lower housing part formed in the support.
Afin de remédier à ces inconvénients, l'invention propose un système d'essuie-glace du type mentionné précédem ment, caractérisé en ce qu'une bride de serrage en forme générale de plaque coopère avec la partie supérieure du tronçon de fixation de la traverse et est interposée entre une tête de l'ensemble de serrage et le support pour assurer le serrage du tronçon de fixation de la traverse dans le fond de la partie de logement inférieure, sans déformation du profil tubulaire du tronçon de fixation de la traverse.

On a représenté sur la figure 1 une traverse tubulaire 20 appartenant à un système d'essuie-glace (non représenté en détails) qui est un tube cylindrique circulaire dont un tronçon de fixation 22 est prévu pour être fixé à un support 24 qui est le support d'un moteur ou d'un groupe motoreducteur (non représenté en détails) pour l'entraînement en balayage alterné des essuie-glaces du système.There is shown in Figure 1 a tubular cross member 20 belonging to a wiper system (not shown in details) which is a circular cylindrical tube of which a fixing section 22 is provided to be fixed to a support 24 which is the support of a motor or a geared motor group (not shown in details) for the drive in alternating sweep of the wipers of the system.
Le support 24 est illustré de manière schématique sous la forme d'un bloc délimité par une face supérieure plane horizontale 26, par une face inférieure plane parallèle 28 et par deux faces verticales transversales 30 qui délimitent la longueur du support 24 mesurée selon la direction de l'axe A du tronçon 22 de fixation de la traverse 20.The support 24 is illustrated schematically in the form of a block delimited by a horizontal flat upper face 26, by a parallel flat lower face 28 and by two transverse vertical faces 30 which delimit the length of the support 24 measured in the direction of the axis A of the section 22 for fixing the crosspiece 20.
La face supérieure 26 comporte un évidement délimité par une portion de face plane supérieure 32 et par une facette longitudinale verticale 34. Une partie de logement inférieure 36 est formée dans la face supérieure 26, 32.The upper face 26 has a recess delimited by an upper flat face portion 32 and by a vertical longitudinal facet 34. A lower housing part 36 is formed in the upper face 26, 32.
La partie de logement inférieure 36 est ici semi-cylindrique concave et elle est parfaitement complémentaire du profil externe cylindrique convexe du tronçon 22 de fixation de la traverse tubulaire 20 qui est destiné à être reçu dans un logement de fixation constitué par la partie de logement inférieure 36 et par une partie de logement supérieure 38 qui, conformément aux enseignements de l'invention, est formée dans une bride de serrage 40. La bride de serrage 40 se présente sous la forme d'un élément rapporté de serrage qui est fixé sur le bloc massif et unitaire constituant le support 24 pour constituer un élément des moyens de fixation de la traverse 20 dans la partie de logement inférieure 36.The lower housing part 36 is here semi-cylindrical concave and it is perfectly complementary to the convex cylindrical external profile of the section 22 for fixing the tubular cross member 20 which is intended to be received in a fixing housing constituted by the lower housing part 36 and by an upper housing part 38 which, in accordance with the teachings of the invention, is formed in a clamp 40. The clamp 40 is in the form of an attached clamping element which is fixed on the solid and unitary block constituting the support 24 to constitute an element of the means for fixing the cross-member 20 in the lower housing part 36.
La bride de serrage 40 est délimitée dans ce cas par une face plane inférieure 42 dans laquelle est formée la partie de logement supérieure 38 et par deux faces transversales opposées 44 de manière que la longueur de la bride 40 soit sensiblement égale à la longueur de la partie du support 24, mesurée selon l'axe A, dans laquelle est formée la partie de logement inférieure. Le corps de la bride 40 est aussi délimité par une face latérale verticale 46 dont la partie inférieure est destinée à venir en appui contre la facette 34 pour positionner de manière précise la bride 40 par rapport au support 24 avec sa face inférieure plane 42 en appui contre la portion de face plane supérieure 32 du support 24. La partie de logement supérieure 38 est semi-cylindrique concave complémentaire de la partie de logement inférieure 36 et complémentaire du profil externe du tronçon de fixation 22 de la traverse tubulaire 20.The clamp 40 is delimited in this case by a lower flat face 42 in which the upper housing part 38 is formed and by two opposite transverse faces 44 so that the length of the flange 40 is substantially equal to the length of the part of the support 24, measured along the axis A, in which the lower housing part is formed. The body of the flange 40 is also delimited by a vertical lateral face 46 the lower part of which is intended to come into abutment against the facet 34 in order to precisely position the flange 40 relative to the support 24 with its flat lower face 42 in abutment against the upper flat face portion 32 of the support 24. The upper housing part 38 is concave semi-cylindrical complementary to the lower housing part 36 and complementary to the external profile of the fixing section 22 of the tubular cross member 20.
Conformément à un aspect de l'invention , les surfaces cylindriques concaves des parties de logement inférieure 36 et supérieure 38 comportent des stries 46 et 48 qui sont ici une série de stries circulaires adjacentes dont chacune s'étend dans un plan transversal.According to one aspect of the invention, the concave cylindrical surfaces of the lower 36 and upper 38 housing portions have ridges 46 and 48 which are here a series of adjacent circular ridges, each of which extends in a transverse plane.
Les stries 46 et 48 sont destinées, lors du serrage de la bride 40, à coopérer avec la surface externe 23 du tronçon de fixation 22 en pénétrant, le cas échéant, légèrement dans le matériau constitutif de la paroi tubulaire de la traverse 20 mais sans provoquer de déformation globale du tronçon de fixation 22, c'est-à-dire sans déformer le tronçon tubulaire. L'invention n'est pas limitée à l'agencement de stries circulaires dans un plan transversal, celle-ci pouvant revêtir différentes formes et orientations ou être remplacées par des pointes ou des ergots formés en relief dans les surfaces concaves qui délimitent les parties de logement inférieure 36 et supérieure 38. Pour assurer la fixation et le serrage de la bride de serrage 40 sur le support 24, le premier mode de réalisation propose de faire appel à deux sous-ensembles de serrage du type vis- écrou.The grooves 46 and 48 are intended, when tightening the flange 40, to cooperate with the external surface 23 of the fixing section 22 by penetrating, if necessary, slightly into the material of the tubular wall of the cross member 20 but without cause overall deformation of the fixing section 22, that is to say without deforming the tubular section. The invention is not limited to the arrangement of circular ridges in a transverse plane, which can take different shapes and orientations or be replaced by points or pins formed in relief in the concave surfaces which delimit the parts of lower housing 36 and upper 38. To ensure the fixing and tightening of the clamp 40 on the support 24, the first embodiment proposes using two clamping sub-assemblies of the screw-nut type.
Chaque sous-ensemble comporte ici un goujon 50 d'axe B qui est porté par la bride 40.Each sub-assembly here comprises a stud 50 of axis B which is carried by the flange 40.
Chaque goujon 50 s'étend verticalement vers le bas à partir de la surface concave de la partie de logement supérieure 38, puis à travers la partie de logement inférieure 36 dans le fond de laquelle sont formés deux perçages débouchants 52 de manière que, en position assemblée, les extrémités inférieures filetées 54 des goujons 50 fassent saillie verticalement en dessous de la face inférieure 28 du support pour permettre le vissage d'un écrou de serrage 56 sur chacune des extrémités filetées 54.Each stud 50 extends vertically downward from the concave surface of the upper housing part 38, then through the lower housing part 36 in the bottom of which are formed two through holes 52 so that, in position assembled, the threaded lower ends 54 of the studs 50 project vertically below the lower face 28 of the support to allow the screwing of a tightening nut 56 on each of the threaded ends 54.
Les deux tiges des goujons 50 s'étendent dans un plan vertical axial et elles traversent donc ici le tronçon de fixation 22 de la traverse tubulaire 20 dont la paroi tubulaire comporte à cet effet deux paires de trous supérieurs 58 et inférieurs 59 alignés par paires et préalablement formés dans le tronçon 22 avec le même entraxe que la distance longitudinale séparant les axes B des goujons 50. Les trous de l'une des paires peuvent être de forme cylindrique alors que ceux de l'autre paire peuvent être de forme légèrement oblongue afin de compenser les dispersions géométriques.The two rods of the studs 50 extend in an axial vertical plane and therefore here pass through the fixing section 22 of the tubular crosspiece 20, the tubular wall of which comprises for this purpose two pairs of upper 58 and lower 59 holes aligned in pairs and previously formed in the section 22 with the same center distance as the longitudinal distance separating the axes B of the studs 50. The holes of one of the pairs can be of cylindrical shape while those of the other pair can be of slightly oblong shape so to compensate for geometric dispersions.
L'assemblage du système d'essuie-glace selon l'invention s'effectue ainsi par exemple en mettant en place la bride 40 avec ses goujons 50 sur le tronçon de fixation 22, puis en venant mettre ce sous- ensemble en place dans la partie de logement inférieure 36 et en procédant ensuite au vissage des écrous 56 jusqu'à ce que les faces planes horizontales 32 et 42 viennent en appui mutuel.The assembly of the wiper system according to the invention is thus carried out for example by installing the flange 40 with its studs 50 on the fixing section 22, then by coming to put this sub-assembly in place in the lower housing part 36 and then proceeding to screw the nuts 56 until the horizontal flat faces 32 and 42 come into mutual support.
I l est bien entendu possible de remplacer les goujons 50 par des vis 50 (voir figures 2 et 3) et de remplacer les écrous 56 par des perçages 54 comportant un taraudage 56 (voir figures 2 à 4).I t is of course possible to replace the studs 50 with screws 50 (see Figures 2 and 3) and replace the nuts 56 with holes 54 having a thread 56 (see Figures 2 to 4).
Dans le cas de l'utilisation d'une vis comme cela est illustré aux figures 2 à 4, la tête 51 de la vis coopère avec une portion en vis-à-vis de face supérieure 43 de la bride de serrage 40 pour obtenir le serrage du tronçon de fixation 22 dans le fond de la partie de logement inférieure 36 formée dans le support 24.In the case of the use of a screw as illustrated in FIGS. 2 to 4, the head 51 of the screw cooperates with a portion facing the upper face 43 of the clamp 40 to obtain the Tightening of the fixing section 22 in the bottom of the lower housing part 36 formed in the support 24.
Dans la variante de réalisation illustrée aux figures 2 et 3, la bride de serrage 40 comporte deux douilles cylindriques tubulaires 60 qui s'étendent verticalement, chacune selon l'axe B d'un ensemble de serrage vis-écrou, depuis la face concave de la partie de logement supérieure 38 à l'intérieur du logement recevant le tronçon de fixation 22.In the alternative embodiment illustrated in FIGS. 2 and 3, the clamping flange 40 comprises two tubular cylindrical sockets 60 which extend vertically, each along the axis B of a screw-nut clamping assembly, from the concave face of the upper housing part 38 inside the housing receiving the fixing section 22.
Chaque douille 60 est reçue dans un trou supérieur 58 du tronçon de fixation 22 dont le diamètre est ainsi plus grand que celui du trou inférieur correspondant 59, qui est lui-même seulement traversé par la partie inférieure de la tige 50 du goujon ou de la vis de serrage.Each socket 60 is received in an upper hole 58 of the fixing section 22, the diameter of which is thus greater than that of the corresponding lower hole 59, which is itself only crossed by the lower part of the rod 50 of the stud or of the clamping screw.
Les douilles 60 permettent le passage des tiges 50 et elles ont pour fonction de rattraper les jeux existant entre les différents éléments. A cet effet, la bride 40 peut être réalisée de préférence en matériau élastique, par exemple en élastomère, le choix d'un tel matériau permettant aussi à la bride 40 d'assurer une fonction de bloc amortisseur entre la traverse tubulaire 20 et le support 24.The sockets 60 allow the passage of the rods 50 and their function is to make up for the play existing between the different elements. For this purpose, the flange 40 can preferably be made of elastic material, for example elastomer, the choice of such a material also allowing the flange 40 to provide a damping block function between the tubular cross member 20 and the support. 24.
Pour un rattrapage efficace des jeux, il est possible aussi d'adopter la variante de réalisation illustrée aux figures 4 et 5 dans lesquelles les douilles 60 sont de forme tronconique avec leur "pointe" orientée vers le bas. Dans ce cas, afin d'éviter d'aboutir à un assemblage hyperstatique, il n'est pas souhaitable que la face inférieure 42 de la bride de serrage 40 vienne en contact avec la face supérieure 26 du support 24.For an effective take-up of the games, it is also possible to adopt the alternative embodiment illustrated in FIGS. 4 and 5 in which the sockets 60 are of frustoconical shape with their "point" facing downwards. In this case, in order to avoid leading to a hyperstatic assembly, it is undesirable for the lower face 42 of the clamp 40 to come into contact with the upper face 26 of the support 24.
A titre de variante non représentée, la bride 40 peut être indépendante pour chaque vis de serrage 50 et réduite à une simple "rondelle" de serrage comportant une partie inférieure tronconique.By way of a variant not shown, the flange 40 can be independent for each clamping screw 50 and reduced to a simple clamping "washer" comprising a frustoconical lower part.
L'agencement de douilles ou cheminées 60 peut aussi être prévu de manière symétrique dans le fond de la partie de logement inférieure 36, à titre de variante non représentée. Par ailleurs, la douille 60 peut venir de matière avec la traverse 20 au lieu de venir avec la bride 40. Dans l'exemple de réalisation illustré à la figure 6, le socle 24 et la bride de serrage 40 sont réalisés venus de matière en une seule pièce par moulage, par exemple en matière plastique.The arrangement of sockets or chimneys 60 can also be provided symmetrically in the bottom of the lower housing part 36, by way of variant not shown. Furthermore, the sleeve 60 can come in one piece with the cross-member 20 instead of coming with the flange 40. In the embodiment illustrated in Figure 6, the base 24 and the clamp 40 are made integrally in one piece by molding, for example plastic.
A cet effet, afin de constituer un sous-ensemble avec une bride "imperdable" avant le montage, la bride de serrage 40 est reliée au support 24 par une portion amincie en forme de bande de liaison 62 qui est déformable élastiquement pour permettre, après moulage, d'amener la bride de serrage 40 vers la position illustrée schématiquement à la figure 6. On décrira maintenant le mode de réalisation illustré aux figuresTo this end, in order to constitute a sub-assembly with a "captive" flange before mounting, the clamp 40 is connected to the support 24 by a thinned portion in the form of a connecting strip 62 which is elastically deformable to allow, after molding, to bring the clamp 40 to the position illustrated schematically in Figure 6. We will now describe the embodiment illustrated in the figures
7 et 8.7 and 8.
Dans ce mode de réalisation , le support 24 présente globalement une conception similaire à celles décrites précédemment.In this embodiment, the support 24 generally has a design similar to those described above.
La bride de serrage 40 est ici réalisée sous la forme d'une pièce en tôle pliée qui , en section transversale, présente sensiblement la forme d'un U couché.The clamp 40 is here produced in the form of a piece of folded sheet metal which, in cross section, has substantially the shape of a coated U.
L'une des branches, supérieure, du U est constituée par une partie en forme de plaque supérieure 66 qui s'étend au dessus du tronçon de fixation 22 de la traverse tubulaire 20 et l'autre branche inférieure parallèle du U est constituée par une partie inférieure en forme de plaque horizontale 68 parallèle à la plaque supérieure 66, la plaque inférieure 68 étant plus courte latéralement que la plaque supérieure 66.One of the upper branches of the U is constituted by an upper plate-shaped part 66 which extends above the fixing section 22 of the tubular cross member 20 and the other parallel lower branch of the U consists of a lower part in the form of a horizontal plate 68 parallel to the upper plate 66, the lower plate 68 being shorter laterally than the upper plate 66.
Les deux plaques 66 et 68 sont reliées par une partie de liaison coudée 70 qui épouse, en partie ou en totalité, le profil cylindrique externe du tronçon 22.The two plates 66 and 68 are connected by a bent connecting part 70 which matches, in part or in whole, the external cylindrical profile of the section 22.
Les plaques supérieure 66 et inférieure 68 comportent chacune au moins un trou 72, 74 de manière à constituer une paire de trous 72, 74 alignés avec les trous 58 et 59 du tronçon de fixation 22 pour le passage de la tige 50 d'une vis de fixation dont l'extrémité inférieure filetée 52 est destinée à être vissée dans le taraudage 56 du perçage 54 formé dans le fond de la partie de logement inférieure 36.The upper 66 and lower 68 plates each have at least one hole 72, 74 so as to constitute a pair of holes 72, 74 aligned with the holes 58 and 59 of the fixing section 22 for the passage of the rod 50 of a screw fixing device, the threaded lower end 52 of which is intended to be screwed into the internal thread 56 of the bore 54 formed in the bottom of the lower housing part 36.
Les portions de plaque 66 et 68 sont initialement parallèles de manière à permettre la mise en place latérale du tronçon 22 par introduction à l'intérieur de la bride de serrage 40, selon la direction D de la figure 7.The plate portions 66 and 68 are initially parallel so as to allow the lateral positioning of the section 22 by introduction inside the clamp 40, in the direction D of FIG. 7.
Lors de l'opération d'assem blage et de fixation, la plaque inférieure horizontale 68 est progressivement déformée pour venir épouser le profil de la partie inférieure du tronçon de fixation 22 sous l'effet des vis de serrage et par coopération avec la surface interne concave de la partie de logement inférieure 36 pour aboutir à la configuration représentée à la figure 8.During the assembly and fixing operation, the horizontal lower plate 68 is gradually deformed to match the profile of the lower part of the fixing section 22 under the effect of the clamping screws and by cooperation with the internal surface. concave of the lower housing part 36 to achieve the configuration shown in FIG. 8.
La plaque supérieure horizontale 66 sur laquelle prennent appui les têtes 51 des vis 50 permet d'améliorer le maintien en rotation et en translation longitudinale du tronçon de fixation 22. Le fait que la plaque supérieure 66 se prolonge latéralement, vers la gauche en considérant la figure 7 et 8, permet la fixation de différents accessoires et/ou la fixation de l'ensemble traverse 20-support 24-bride 40 sur le véhicule. Dans le mode de réalisation illustré à la figure 9, les vis de fixation 50 ne traversent plus le tronçon de fixation 22 de la traverse tubulaire 20 mais elles sont décalées latéralement de part et d'autre du tronçon 22 avec leurs axes de serrage B parallèles.The horizontal upper plate 66 on which the heads 51 of the screws 50 bear makes it possible to improve the retention in rotation and in longitudinal translation of the fixing section 22. The fact that the upper plate 66 extends laterally, to the left considering the Figure 7 and 8, allows the attachment of different accessories and / or the attachment of the cross-member 20-support 24-flange 40 on the vehicle. In the embodiment illustrated in FIG. 9, the fixing screws 50 no longer pass through the fixing section 22 of the tubular cross member 20 but they are offset laterally on either side of the section 22 with their parallel tightening axes B .
Ainsi, la bride 40 est réalisée globalement sous la forme d'un cavalier de bridage, par exemple en tôle pliée, avec une portion centrale 75 délimitant la partie de logement supérieure 38 et deux ailes latérales et opposées 76 délimitant la face inférieure horizontale 42 de la bride de serrage 40 destinée à venir en appui contre les portions en vis-à-vis de la face supérieure horizontale 26 du support ou socle 24. A la figure 9, les extrémités inférieures filetées des vis 50 sont vissées dans des écrous 56.Thus, the flange 40 is produced overall in the form of a clamping jumper, for example in folded sheet, with a central portion 75 delimiting the upper housing part 38 and two lateral and opposite wings 76 delimiting the horizontal lower face 42 of the clamp 40 intended to come into abutment against the portions facing the horizontal upper face 26 of the support or base 24. In FIG. 9, the threaded lower ends of the screws 50 are screwed in nuts 56.
Sur la variante schématisée à la figure 1 0, les vis 50 sont montées de manière inverse, c'est-à-dire que leurs extrémités filetées sont montées vissées dans des trous taraudés 54 formés dans les ailes 76 de la bride de serrage 40, celle-ci étant alors de préférence réalisée par moulage.In the variant shown diagrammatically in FIG. 1 0, the screws 50 are mounted in reverse, that is to say that their threaded ends are mounted screwed into tapped holes 54 formed in the wings 76 of the clamp 40, the latter then preferably being produced by molding.
Dans la variante illustrée à la figure 1 1 , chaque ensemble de serrage selon un axe B de la bride de serrage 40 sur le support 24 est constitué par un rivet 77, par exemple un rivet "pop". Dans la variante illustrée à la figure 1 2, chaque ensemble de serrage selon l'axe B est constitué par une tige 50 réalisée par exemple venue de matière avec le support 24 et qui s'étend verticalement selon l'axe B à travers un trou 72 formé dans l'aile 76 correspondant de la bride de serrage 40 et dont l'extrémité libre supérieure est ensuite écrasée par sertissage pour constituer une tête ou pion de serrage 79.In the variant illustrated in Figure 1 1, each clamping assembly along an axis B of the clamp 40 on the support 24 is constituted by a rivet 77, for example a "pop" rivet. In the variant illustrated in Figure 1 2, each clamping assembly along the axis B is constituted by a rod 50 made for example made of one piece with the support 24 and which extends vertically along the axis B through a hole 72 formed in the corresponding wing 76 of the clamp 40 and whose upper free end is then flattened by crimping to constitute a clamping head or pin 79.
On décrira maintenant le mode de réalisation illustré aux figures 1 3 et 14 dans lequel, comme dans le cas de celui illustré à la figure 9, la (ou les) vis de serrage 50 ne traverse(nt) pas le tronçon 22 de la traverse tubulaire 20.We will now describe the embodiment illustrated in Figures 1 3 and 14 in which, as in the case of that illustrated in Figure 9, the (or) clamping screw 50 does (s) not cross (s) the section 22 of the cross tubular 20.
La bride de fixation et de serrage 40 est de conception globalement similaire à celle illustrée à la figure 9 et l'une de ses ailes latérales 76, de gauche en considérant la figure 1 3, est serrée par une ou des vis 50 sur une partie correspondante du support 24. L'autre aile latérale 76' , à droite en considérant la figure 1 3, est inclinée vers le bas et elle prend appui sur une portion de face supérieure inclinée correspondante 32' du support 24.The fastening and clamping flange 40 is generally similar in design to that illustrated in FIG. 9 and one of its lateral wings 76, on the left considering FIG. 1 3, is tightened by one or more screws 50 on one part corresponding to the support 24. The other lateral wing 76 ′, on the right when considering FIG. 1 3, is inclined downward and it bears on a corresponding inclined upper face portion 32 ′ of the support 24.
L'aile 76' est conformée, comme on peut le voir à la figure 14, en une patte d'articulation de charnière 76' dont les branches longitudinales 80' prennent appui sur deux ergots 82' du support pour constituer une charnière d'articulation de la bride de serrage 40 qui est ainsi serrée, par les vis 50, en arc-boutement autour du tronçon de fixation 22 de la traverse tubulaire 20.The wing 76 ′ is shaped, as can be seen in FIG. 14, into a hinge articulation lug 76 ′ whose longitudinal arms 80 ′ bear on two lugs 82 ′ of the support to constitute a hinge articulation of the clamp 40 which is thus tightened, by the screws 50, in bracing around the fixing section 22 of the tubular cross member 20.
Le montage s'effectue, après avoir mis en place le tronçon de fixation 22 dans la partie de logement inférieure 36, en introduisant les pattes 80' sous les ergots 82', puis en basculant la bride de serrage 40 jusqu'à ce que son aile 76 vienne en regard de la partie correspondante du socle 24. La fixation s'effectue en introduisant la (ou les) vis de serrage 50 et la(les) vissant dans les trous taraudés 52, 56 du support. L'agencement de la bride articulée 40 dont le serrage est effectué par arc-boutement autour de la traverse tubulaire 20, 22 permet aussi de réaliser un pré-positionnement et un pré-montage de la bride 40 sur le socle 24, sans serrage complet des vis 50, puis d'introduire axialement selon l'axe A la traverse tubulaire 20 dans le logement 36- 38, et enfin d'effectuer l'opération finale de bridage par serrage des vis 50.The assembly is carried out, after having set up the fixing section 22 in the lower housing part 36, by introducing the tabs 80 'under the lugs 82', then by tilting the clamp 40 until its wing 76 comes opposite the corresponding part of the base 24. The fixing is carried out by introducing the clamping screw (s) 50 and the screw (s) screwing into the tapped holes 52, 56 of the support. The arrangement of the articulated flange 40, the tightening of which is effected by bracing around the tubular cross member 20, 22 also makes it possible to pre-position and pre-mount the flange 40 on the base 24, without complete tightening. screws 50, then introduce axially along the axis A the tubular cross member 20 into the housing 36- 38, and finally to carry out the final clamping operation by tightening the screws 50.
Le mode de réalisation illustré aux figures 1 5 et 16, qui est aussi du type à serrage par arc-boutement de la bride 40, diffère de celui illustré et décrit en référence aux figures 1 3 et 14 par les moyens d'articulation de l'aile latérale 76' de la bride de serrage 40.The embodiment illustrated in Figures 1 5 and 16, which is also of the clamping type by bracing of the flange 40, differs from that illustrated and described with reference to Figures 1 3 and 14 by the means of articulation of the 'side wing 76' of the clamp 40.
En effet, l'aile 76' est ici conformée en un manchon cylindrique de forme oblongue orienté selon un axe vertical (voir figure 1 6) dans lequel est reçu avec jeu un doigt cylindrique 84' du support 24 qui s'étend horizontalement et latéralement vers la droite pour être reçu à l'intérieur du manchon 76' dans lequel il peut se déplacer verticalement.Indeed, the wing 76 'is here shaped as a cylindrical sleeve of oblong shape oriented along a vertical axis (see Figure 1 6) in which is received with play a cylindrical finger 84' of the support 24 which extends horizontally and laterally to the right to be received inside the sleeve 76 'in which it can move vertically.
On voit aussi sur la figure 1 5 que l'aile latérale de gauche 76 de la bride 40 peut se prolonger vers l'extérieur par une partie 86 permettant notamment la fixation de l'ensemble sur le véhicule et/ou la fixation d'accessoires sur cette partie 86 de la bride de serrage 40. It can also be seen in FIG. 1 5 that the left lateral wing 76 of the flange 40 can be extended towards the outside by a part 86 allowing in particular the fixing of the assembly to the vehicle and / or the fixing of accessories on this part 86 of the clamp 40.
