Description

La présente invention se rapporte à une charnière et vise plus particulièrement une charnière pour porte de véhicule automobile comportant un premier charnon fixé à un ouvrant et relié, par un axe d'articulation rapporté, à un second charnon fixé à la structure du véhicule.The present invention relates to a hinge and aims more particularly a hinge for a motor vehicle door comprising a first knuckle fixed to an opening and connected, by a hinge pin reported, to a second knuckle attached to the structure of the vehicle.

Classiquement, les premier et second charnons des charnières munies d'un axe d'articulation rapporté comportent au moins un prolongement pourvu d'un alésage destiné à recevoir l'axe d'articulation de façon à former un élément de maintien de l'axe d'articulation. Cet alésage porté par les charnons est généralement entouré d'une face d'appui circulaire, perpendiculaire à l'axe de l'alésage, destinée à venir en appui contre la face d'appui de l'élément de maintien du charnon venant en vis à vis, empêchant ainsi tout mouvement relatif des premier et second charnon suivant la direction de l'axe d'articulation.Conventionally, the first and second hinges of the hinges fitted with an attached hinge pin have at least one extension provided with a bore intended to receive the articulation axis of so as to form a holding element for the hinge pin. This bore carried by the knuckles is generally surrounded by a circular bearing face, perpendicular to the axis of the bore, intended to bear against the face support of the hinge holding element coming opposite, preventing thus any relative movement of the first and second knuckles following the direction of the articulation axis.

De telles charnières présentent l'inconvénient de rendre délicat l'assemblage de la porte sur le véhicule, la mise en place des axes d'articulation rapportés, qui s'effectue alors que la porte est en position ouverte pour avoir accès aux charnières, nécessitant préalablement la mise en contact des faces d'appui et l'alignement des alésages portés par les éléments de maintien des différents charnons. Cet alignement est d'autant plus difficile à effectuer que le poids de la porte est important et il n'est pas rare, lors de l'opération de montage de cette dernière, que la partie avant de la porte vienne heurter le véhicule, endommageant ainsi le bord ou la peau extérieure de cette dernière. Ces dommages crées par le contact ponctuel du bord de la porte sur un élément du véhicule entraíne des retouches coûteuses des pièces pour lesquelles l'aspect extérieur, reflétant la qualité du produit, doit être parfait. Such hinges have the drawback of making them delicate assembling the door on the vehicle, setting up the axes hinge, which takes place while the door is in position open to have access to the hinges, requiring prior installation contact of the bearing faces and the alignment of the bores carried by the elements holding the different knuckles. This alignment is all the more difficult to carry out that the weight of the door is important and it is not rare, during the assembly operation of the latter, that the front part of the door strike the vehicle, damaging the edge or the outer skin of the latter. This damage created by the point contact of the edge of the relates to an element of the vehicle entails costly touch-up of the parts for which the external appearance, reflecting the quality of the product, must be perfect.

Il est connu, pour réduire les risques de dommages au montage, de dessiner des portes possédant des lignes à faible courbure du côté des charnières et de laisser un espace adapté entre le bord de la portière et les éléments du véhicule afin de permettre un débattement suffisant de la porte autour de la position d'engagement des axes d'articulation sans que ceci ne génère de chocs entre la portière et le véhicule.It is known to reduce the risk of damage to the assembly, to draw doors with lines with small curvature on the side of hinges and leave a suitable space between the edge of the door and the vehicle components to allow sufficient door travel around the engagement position of the hinge pins without this generates shocks between the door and the vehicle.

Toutefois, l'aspect extérieur des véhicules étant de plus en plus important, il devient nécessaire de réduire l'espace entre la porte et la carrosserie, lorsque celle ci est en position fermée, et de pouvoir développer des portières au dessin galbé, possédant des lignes aux courbures prononcées du côté des charnières.However, the exterior appearance of vehicles is increasingly important, it becomes necessary to reduce the space between the door and the bodywork, when it is in the closed position, and to be able to develop curved doors, with pronounced curvature lines on the side of the hinges.

Le montage de ces portes, dont l'espace libre entre le bord de la porte et le véhicule est réduit lorsque la porte est en position ouverte, nécessite un soin particulier, non compatible avec le montage à la chaíne, pour éviter la multiplication des dommages résultant d'un léger dépassement de la position d'engagement des axes d'articulation.The mounting of these doors, including the free space between the edge of the door and the vehicle is reduced when the door is in the open position, requires special care, not compatible with chain assembly, to avoid the multiplication of damage resulting from a slight overshoot the engagement position of the hinge pins.

Le but de la présente invention est donc de proposer une charnière, ainsi qu'une porte équipée de cette charnière, facilitant le montage de l'axe d'articulation rapporté en supprimant les risques de dépassement prononcé de la position d'engagement de ce dernier et qui soit simple et économique à réaliser.The object of the present invention is therefore to propose a hinge, as well as a door fitted with this hinge, facilitating assembly of the hinge pin added by eliminating the risk of overshoot pronounced from the engagement position of the latter and which is simple and economical to achieve.

Selon encore une autre caractéristique de la charnière selon l'invention, les moyens de guidage limitent les déplacements relatifs de la porte par rapport à la structure du véhicule selon un plan perpendiculaire à l'axe d'articulation.According to yet another characteristic of the hinge according to the invention, the guide means limit the relative displacements of the door relative to the structure of the vehicle along a plane perpendicular to the axis of articulation.

Selon une autre caractéristique de la charnière selon l'invention, les moyens de guidage se composent d'une paroi en saillie portée par l'élément de maintien du second charnon et de l'extrémité de l'élément de maintien du premier charnon, la paroi en saillie étant de forme adaptée de façon à entourer partiellement l'extrémité de l'élément de maintien du premier charnon. According to another characteristic of the hinge according to the invention, the guide means consist of a projecting wall carried by the holding element of the second knuckle and the end of the element of maintenance of the first knuckle, the projecting wall being of a shape adapted to so as to partially surround the end of the holding element of the first knuckle.

Par ailleurs, seuls les éléments nécessaires à la compréhension de l'invention ont été figurés.To facilitate the reading of the drawings, the same parts bear the same references from one figure to another. Furthermore, only the elements necessary for understanding the invention have been shown.

La figure 1 présente une charnière pour porte de véhicule automobile se composant d'un premier charnon 1 relié à la porte d'un véhicule et d'un second charnon 2 fixé à un élément de structure du véhicule et relié au premier charnon 1 par un axe d'articulation, non représenté sur la figure.Figure 1 shows a hinge for a vehicle door automobile consisting of a first knuckle 1 connected to the door of a vehicle and a second knuckle 2 fixed to a structural element of the vehicle and connected to the first knuckle 1 by a hinge pin, not shown in the figure.

Comme on peut le voir plus précisément sur les figures 1 et 2, le premier charnon est composé d'un pied 21 comportant deux trous de fixation permettant sa fixation sur la porte du véhicule et de deux éléments de maintien 3a et 3b s'étendant depuis un bord latéral du pied 21, dans une direction sensiblement perpendiculairement à ce dernier.As can be seen more precisely in Figures 1 and 2, the first knuckle is composed of a foot 21 comprising two fixing holes allowing its attachment to the vehicle door and two elements of holding 3a and 3b extending from a lateral edge of the foot 21, in a direction substantially perpendicular to the latter.

Chaque élément de maintien 3a et 3b du premier charnon 1 comporte respectivement un alésage 6a et 6b disposé dans un même axe de façon à recevoir l'axe d'articulation, non représenté sur les figures, solidarisant le premier charnon 1 au second charnon 2. Ces alésages 6a et 6b du premier charnon 1 débouchent respectivement sur deux faces d'appui 5a et 5b en vis à vis, destinées à venir respectivement en regard de faces d'appui du second charnon 2.Each holding element 3a and 3b of the first knuckle 1 comprises respectively a bore 6a and 6b arranged in the same axis of so as to receive the hinge pin, not shown in the figures, joining the first knuckle 1 to the second knuckle 2. These bores 6a and 6b of the first knuckle 1 open respectively on two bearing faces 5a and 5b facing each other, intended to come respectively opposite bearing faces second knuckle 2.

En se reportant aux figures 1 et 3, on voit que le second charnon 2 est composé d'un pied 22 se fixant par soudage à l'élément de structure du véhicule et d'un élément de maintien 4 s'étendant depuis un bord latéral du pied 22 dans une direction sensiblement perpendiculairement à ce dernier.Referring to Figures 1 and 3, we see that the second knuckle 2 is composed of a foot 22 which is fixed by welding to the structural element of the vehicle and a holding element 4 extending from a lateral edge of the foot 22 in a direction substantially perpendicular to the latter.

L'élément de maintien 4 du second charnon 2 comporte, à proximité de son extrémité, un alésage 7 destiné à recevoir l'axe d'articulation reliant le second charnon 2 au premier charnon 1. The holding element 4 of the second knuckle 2 comprises, at near its end, a bore 7 intended to receive the hinge pin connecting the second knuckle 2 to the first knuckle 1.

Cet alésage 7 débouche de part et d'autre de l'élément de maintien 4 sur deux faces d'appui 8a et 8b circulaires destinées à venir respectivement en regard des faces d'appui 5a et 5b du premier charnon 1.This bore 7 opens on either side of the element of holding 4 on two support faces 8a and 8b circular intended to come respectively facing the bearing faces 5a and 5b of the first knuckle 1.

L'élément de maintien 4 du second charnon comporte également à son extrémité deux faces de guidages 14a et 14b respectivement juxtaposées aux faces d'appui 8a et 8b portées par l'extrémité de l'élément de maintien 4. Ces faces de guidage 14a et 14b sont légèrement inclinées l'une par rapport à l'autre de façon à ce que l'extrémité de l'élément de maintien 4 soit convergente.The holding element 4 of the second knuckle also comprises at its end two guide faces 14a and 14b respectively juxtaposed with the bearing faces 8a and 8b carried by the end of the element holding 4. These guide faces 14a and 14b are slightly inclined one relative to each other so that the end of the holding element 4 either converge.

Pour faciliter l'accostage du premier charnon 1 sur le second charnon 2 suivant la direction de l'axe d'articulation, l'élément de maintien 3a du premier charnon 1, représenté sur la figure 2, comporte une partie 9 se prolongeant au delà de l'alésage 6a. Cette partie 9 comprend, dans le prolongement de la face d'appui 5a, une paroi d'appui 10 dont les dimensions sont adaptées pour coopérer avec la face d'appui 8a du second charnon 2. Cette paroi d'appui 10 est inclinée d'environ 1° par rapport à la face d'appui 5a de façon à ce que l'angle formé par ces deux faces soit saillant.To facilitate docking of the first knuckle 1 on the second knuckle 2 in the direction of the hinge axis, the holding element 3a of the first knuckle 1, shown in FIG. 2, has a part 9 extending beyond bore 6a. This part 9 includes, in the extension of the bearing face 5a, a bearing wall 10 whose dimensions are adapted to cooperate with the bearing face 8a of the second knuckle 2. This support wall 10 is inclined by about 1 ° relative to the support face 5a so that the angle formed by these two faces is projecting.

De même, afin de faciliter l'accostage du premier charnon 1 sur le second charnon 2 suivant le plan perpendiculaire à l'axe d'articulation, l'élément de maintien 4 du second charnon 2, représenté sur la figure 3, comporte une paroi 11 en saillie de quelques millimètres bordant partiellement la face d'appui 8b et longeant un bord de la face de guidage 14b. Cet paroi 11, de forme circulaire autour de la face d'appui 8b, est disposée uniquement sur la partie de la face d'appui 8b et de la face de guidage 14b orientée vers l'avant et vers l'intérieur du véhicule afin de permettre l'approche, par l'autre coté, de la face d'appui 5b du premier charnon 1.Similarly, in order to facilitate docking of the first knuckle 1 on the second knuckle 2 along the plane perpendicular to the hinge axis, the holding element 4 of the second knuckle 2, shown in FIG. 3, has a wall 11 projecting a few millimeters bordering partially the bearing face 8b and along an edge of the guide face 14b. This wall 11, of circular shape around the bearing face 8b, is disposed only on the part of the support face 8b and of the face of guide 14b oriented towards the front and towards the interior of the vehicle in order to allow the approach, from the other side, of the bearing face 5b of the first knuckle 1.

Une fois la charnière assemblée, ainsi qu'elle est représentée sur la figure 1, les deux éléments de maintien 3a et 3b du premier charnon 1 viennent de part et d'autre de l'élément de maintien 4 du second charnon 2 afin d'effectuer le blocage en translation des charnons suivant la direction de l'axe d'articulation, le blocage en translation suivant le plan perpendiculaire à l'axe d'articulation étant réalisé par l'axe lui-même.Once the hinge is assembled, as shown in Figure 1, the two holding elements 3a and 3b of the first knuckle 1 come from either side of the holding element 4 of the second knuckle 2 in order to block in translation the knuckles in the direction of the axis of articulation, the blocking in translation along the plane perpendicular to the articulation axis being produced by the axis itself.

La phase de montage sur un véhicule d'une porte, équipée de telles charnières, est représentée sur la figure 4.The assembly phase on a vehicle of a door, equipped with such hinges, is shown in Figure 4.

Cette figure présente une porte équipée d'une première charnière 12, identique à celle décrite sur les figures 1 à 3, disposée dans la partie inférieure de la porte et d'une seconde charnière 13, symétrique de la charnière 12 par rapport au plan médian perpendiculaire à l'axe des charnières, disposée suivant le même axe, dans la partie supérieure de la porte.This figure shows a door fitted with a first hinge 12, identical to that described in FIGS. 1 to 3, arranged in the part bottom of the door and a second hinge 13, symmetrical to the hinge 12 with respect to the median plane perpendicular to the axis of hinges, arranged along the same axis, in the upper part of the door.

Lors de la phase de montage de la porte sur le véhicule, comme on peut le voir sur la figure 4, la porte est amenée en direction du véhicule en position ouverte. L'opérateur manoeuvre alors la porte de façon à ce que, pour chacune des charnières 12 et 13, la paroi d'appui 10 de l'élément de maintien 3a du premier charnon 1 vienne en regard de la face d'appui 8a portée par l'élément de maintien 4 du second charnon 2. Cette mise en place de la porte est facilitée par l'inclinaison d'environ 1° de la normale des parois d'appui 10 par rapport à l'axe d'articulation permettant d'augmenter l'intervalle entre les parois d'appui 10 ainsi que par l'extrémité convergente de l'élément de maintien 4 des second charnons 2 au niveau des faces de guidages 14a et 14b.During the assembly phase of the door on the vehicle, as we can see it in figure 4, the door is brought towards the vehicle by open position. The operator then maneuvers the door so that, for each of the hinges 12 and 13, the bearing wall 10 of the element of holding 3a of the first knuckle 1 comes opposite the bearing face 8a carried by the holding element 4 of the second knuckle 2. This positioning of the door is facilitated by the inclination of about 1 ° from the normal of the walls support 10 with respect to the articulation axis making it possible to increase the interval between the support walls 10 as well as by the converging end of the holding element 4 of the second knuckles 2 at the faces of guides 14a and 14b.

La paroi d'appui 10 du premier charnon 1 de la charnière 13 est ensuite amenée contre la face d'appui 8a du second charnon 2, un léger jeu apparaissant alors entre la paroi d'appui 10 et la face d'appui 8a de la charnière 12.The support wall 10 of the first knuckle 1 of the hinge 13 is then brought against the bearing face 8a of the second knuckle 2, a slight clearance then appearing between the support wall 10 and the support face 8a of the hinge 12.

La porte est alors poussée par l'opérateur, perpendiculairement à l'axe des charnières, de façon à ce que pour chaque charnière 12 et 13, la face d'appui 5b du second charnon 2 soit engagée sur la face de guidage 14b du premier charnon 1 et que simultanément l'extrémité de l'élément de maintien 3b du premier charnon 1 vienne en contact avec la paroi 11 du second charnon 2.The door is then pushed by the operator, perpendicular to the axis of the hinges, so that for each hinge 12 and 13, the bearing face 5b of the second knuckle 2 is engaged on the guide face 14b of the first knuckle 1 and that simultaneously the end of the element of holding 3b of the first knuckle 1 comes into contact with the wall 11 of the second knuckle 2.

Le guidage de l'élément de maintien 3b du premier charnon 1 sur la paroi 11 du second charnon 2 associé à la poussée de l'opérateur sur la porte amène enfin cette dernière en position finale où l'extrémité circulaire de l'élément de maintien 3b du premier charnon 1 est en appui contre la portion en arc de cercle de la paroi 11 du second charnon 2.The guidance of the holding element 3b of the first knuckle 1 on the wall 11 of the second knuckle 2 associated with the thrust of the operator on the door finally brings the latter to the final position where the circular end of the holding element 3b of the first knuckle 1 is in abutment against the portion in an arc of a wall 11 of the second knuckle 2.

Les alésages 6a, 6b et 7 étant alors sensiblement coaxiaux, la mise en place des axes est simplifiée, ces derniers ayant des bords chanfreinés permettant de rattraper les légers décalages. La mise en place de l'axe permet alors de recentrer les alésages 6a, 6b et 7, les dimensions des premier et second charnon 1 et 2 étant adaptées afin de laisser un léger jeu entre l'extrémité de l'élément de maintien 3b du premier charnon 1 et la paroi 11 du second charnon 2 pour permettre leur libre rotation.The bores 6a, 6b and 7 then being substantially coaxial, the positioning of the axes is simplified, the latter having chamfered edges allowing to make up for slight shifts. The establishment of the axis allows then to refocus the bores 6a, 6b and 7, the dimensions of the first and second knuckle 1 and 2 being adapted to leave a slight play between the end of the holding element 3b of the first knuckle 1 and the wall 11 of the second knuckle 2 to allow their free rotation.

La charnière ainsi réalisée permet le montage rapide de portes sur un véhicule et ceci sans risque de dépassement de la position de montage de l'axe d'articulation, la charnière intégrant des faces de guidage limitant tout dépassement.The hinge thus produced allows rapid mounting of doors on a vehicle and this without risk of exceeding the mounting position of the hinge pin, the hinge incorporating guide faces limiting everything overshoot.

Cette charnière est particulièrement intéressante pour le montage de portes possédant, en position ouverte, un très faible jeu entre un élément du véhicule et le bord extérieur de la porte, comme par exemple des portes aux lignes courbes au niveau des charnières ou avec un très faible jeu entre la porte et la carrosserie. En effet, en limitant les risques de choc entre la tôle de porte et le véhicule, la charnière selon l'invention permet de réduire considérablement le nombre de retouches à effectuer sur les portes, ce qui permet de compenser largement le surcoût de cette charnière par rapport à une charnière traditionnelle.This hinge is particularly interesting for mounting of doors having, in the open position, a very small clearance between an element of the vehicle and the outer edge of the door, such as doors with curved lines at the hinges or with very little play between the door and bodywork. Indeed, by limiting the risks of impact between the sheet door and the vehicle, the hinge according to the invention makes it possible to reduce considerably the number of alterations to be made on the doors, which largely compensates for the additional cost of this hinge compared to a traditional hinge.

Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple. Of course, the invention is in no way limited to the modes of realization described and illustrated which have been given only by way of example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.On the contrary, the invention includes all equivalents techniques of the means described as well as their combinations if these are carried out according to his spirit.

Ainsi, les charnières montées sur les portes peuvent être identiques, quelles soient montées dans la partie supérieure ou inférieure de la porte.Thus, the hinges mounted on the doors can be identical, whether mounted in the upper or lower part of the door.

Ainsi, les moyens de guidage de la porte lors de son accostage sur le véhicule peuvent être portés par une seule des charnières équipant la porte.Thus, the means for guiding the door during its docking on the vehicle can be carried by only one of the hinges fitted to the door.

Ainsi, les moyens de guidage de la porte lors de son accostage sur le véhicule peuvent être portés par des appendices des charnières n'appartenant pas aux éléments de maintien de l'axe d'articulation.Thus, the means for guiding the door during its docking on the vehicle can be carried by hinge appendages not belonging to the elements for holding the hinge pin.
