Description

La présente invention a pour objet une charnière de porte arrière de véhicule automobile.The present invention relates to a rear door hinge of motor vehicle.

Certains véhicules automobiles, comme par exemple les véhicules utilitaires du type fourgonnette, sont équipés de portes arrière déplaçables entre une position fermée et une position ouverte appliquée contre le côté de la caisse du véhicule de façon à dégager complètement le plancher de chargement et à ne pas déborder de manière importante sur la largeur de ce véhicule pendant les opérations de chargement et de déchargement.Certain motor vehicles, such as vehicles van-type utilities, have movable rear doors between a closed position and an open position applied against the side of the vehicle body so as to completely clear the load floor and not to extend significantly over the width of this vehicle during loading and unloading operations.

Pour permettre le pivotement de la porte entre les deux positions extrêmes, cette porte est équipée d'une charnière qui comporte un charnon fixe monté sur la caisse du véhicule, un charnon mobile monté sur la porte et un charnon intermédiaire relié à chacun desdits charnons par un axe de rotation de façon à autoriser un pivotement de ladite porte sur environ 250°.To allow the door to pivot between the two positions extreme, this door is fitted with a hinge which includes a fixed knuckle mounted on the vehicle body, a movable knuckle mounted on the door and a intermediate knuckle connected to each of said knuckles by an axis of rotation of so as to allow the door to pivot about 250 °.

La charnière comporte un organe de blocage coopérant avec chacun des axes pour les verrouiller en rotation alternativement et permettre successivement le pivotement du charnon mobile autour de son axe sur un angle compris entre 0 et 180°, puis le pivotement de l'ensemble constitué par le charnon intermédiaire et le charnon mobile autour de l'axe du charnon fixe sur un angle compris entre 180 et 250° environ.The hinge comprises a blocking member cooperating with each of the axes to lock them in rotation alternately and allow successively the pivoting of the movable knuckle about its axis on an angle between 0 and 180 °, then the pivoting of the assembly constituted by the knuckle intermediate and the knuckle moving around the axis of the knuckle fixed at an angle between approximately 180 and 250 °.

Dans les charnières utilisées jusqu'à présent, l'organe de blocage est formé par une pièce maintenue sur le charnon intermédiaire au moyen de deux éléments de vissage qui traversent chacun cette pièce par un trou oblong.In the hinges used so far, the locking member is formed by a part held on the intermediate knuckle by means of two screwing elements which each pass through this part through an oblong hole.

Lors de l'ouverture de la porte, l'organe de blocage coulisse et bloque successivement les deux axes en venant en contact avec un méplat aménagé sur chacun de ces axes afin de permettre, dans un premier temps, le pivotement du charnon mobile seul et, dans un second temps, le pivotement de l'ensemble formé par le charnon mobile et le charnon intermédiaire.When the door is opened, the locking member slides and successively blocks the two axes by coming into contact with a flat fitted out on each of these axes in order to allow, as a first step, the pivoting of the movable knuckle alone and, in a second step, the pivoting of the assembly formed by the mobile knuckle and the intermediate knuckle.

Lors de la fermeture de la porte, l'organe de blocage bloque d'abord l'axe du charnon mobile pour permettre le pivotement de l'ensemble formé par le charnon mobile et le charnon intermédiaire autour de l'axe du charnon fixe et bloque ensuite l'axe du charnon fixe de façon à autoriser le pivotement uniquement du charnon mobile autour de son axe. When the door is closed, the blocking device blocks first the axis of the movable knuckle to allow the pivoting of the assembly formed by the mobile knuckle and the intermediate knuckle around the knuckle axis then fixes and blocks the axis of the fixed knuckle so as to allow pivoting only knuckle movable around its axis.

Ce type de montage de l'organe de blocage sur le charnon intermédiaire a pour inconvénient d'entraíner le perçage du charnon intermédiaire ainsi que l'usinage des trous oblongs dans cet organe de blocage et des opérations d'assemblage de ces divers éléments.This type of mounting of the blocking member on the intermediate knuckle has the disadvantage of causing the drilling of the intermediate knuckle as well as the machining of the oblong holes in this blocking member and operations assembly of these various elements.

L'invention a pour but d'éviter ces inconvénients.The invention aims to avoid these drawbacks.

A cet effet, l'invention a pour objet une charnière de porte arrière de véhicule automobile, du type comprenant :

La charnière représentée sur les figures et désignée dans son ensemble par la référence 10 est destinée à être montée entre une caisse 1 d'un véhicule automobile et une porte arrière 2 déplaçable entre une position fermée et une position ouverte dans laquelle cette porte arrière 2 est appliquée contre le côté de ladite caisse 1.The hinge shown in the figures and designated in its together by the reference 10 is intended to be mounted between a body 1 of a motor vehicle and a rear door 2 movable between a closed position and an open position in which this rear door 2 is applied against the side of said body 1.

Ainsi que représenté sur les Figs. 1 à 3, la charnière 10 comprend :

  • un charnon fixe 20 monté sur la caisse 1 du véhicule,
  • un charnon mobile 30 monté sur la porte arrière 2, et
  • un charnon intermédiaire 40 relié à chacun desdits charnons 20 et 30.
As shown in Figs. 1 to 3, the hinge 10 includes:
  • a fixed knuckle 20 mounted on the body 1 of the vehicle,
  • a movable knuckle 30 mounted on the rear door 2, and
  • an intermediate knuckle 40 connected to each of said knuckles 20 and 30.

Le charnon fixe 20 se présente sous la forme d'une chape comportant, d'une part, une plaque 21 destinée à être fixée sur la caisse 1 du véhicule au moyen par exemple d'éléments de vissage, non représentés, et, d'autre part, deux flasques respectivement 22 et 23, parallèles et s'étendant perpendiculairement à ladite plaque 21.The fixed knuckle 20 is in the form of a yoke comprising, on the one hand, a plate 21 intended to be fixed on the body 1 of the vehicle by means for example of screwing elements, not shown, and, on the other hand, two flanges 22 and 23 respectively, parallel and extending perpendicularly to said plate 21.

De même, le charnon mobile 30 se présente sous la forme d'une chape comportant, d'une part, une plaque 31 destinée à être fixée sur la porte arrière 2 à l'aide par exemple d'éléments de vissage, non représentés, et, d'autre part, de deux flasques, respectivement 32 et 33, parallèles et s'étendant perpendiculairement à ladite plaque 31.Similarly, the mobile knuckle 30 is in the form of a yoke comprising, on the one hand, a plate 31 intended to be fixed on the door rear 2 using for example screw elements, not shown, and, on the other part, of two flanges, respectively 32 and 33, parallel and extending perpendicularly to said plate 31.

Ainsi que représenté sur les Figs. 2 et 3, le charnon intermédiaire 40 est monté entre les flasques 22 et 23 du charnon fixe 21 et les flasques 32 et 33 du charnon mobile 31.As shown in Figs. 2 and 3, the intermediate knuckle 40 is mounted between the flanges 22 and 23 of the fixed knuckle 21 and the flanges 32 and 33 of the movable knuckle 31.

Ce charnon intermédiaire 40 comprend une plaque 41 comportant deux flasques, respectivement 42 et 43, parallèles et perpendiculaires à ladite plaque 41, comme représenté sur les Figs. 3 et 5.This intermediate knuckle 40 comprises a plate 41 comprising two flanges, respectively 42 and 43, parallel and perpendicular to said plate 41, as shown in Figs. 3 and 5.

Le charnon intermédiaire 40 est relié, d'une part, au charnon fixe 20 par un axe 11 qui traverse les flasques 22 et 23 de ce charnon fixe 20 et les flasques 42 et 43 du charnon intermédiaire 40 et, d'autre part, au charnon mobile 30 par un axe 15 qui traverse les flasques 32 et 33 de charnon mobile 30 et les flasques 42 et 43 dudit charnon intermédiaire 40.The intermediate knuckle 40 is connected, on the one hand, to the fixed knuckle 20 by an axis 11 which passes through the flanges 22 and 23 of this fixed knuckle 20 and the flanges 42 and 43 of the intermediate knuckle 40 and, on the other hand, to the mobile knuckle 30 by an axis 15 which passes through the flanges 32 and 33 of movable knuckle 30 and the flanges 42 and 43 of said intermediate knuckle 40.

Ainsi que représenté à la Fig. 4, l'axe 11 disposé entre le charnon fixe 20 et le charnon intermédiaire 40 est placé dans une douille 12 solidaire dudit charnon fixe 20. Cette douille 12 comporte un méplat 13 sur sa face externe.As shown in FIG. 4, axis 11 disposed between the knuckle fixed 20 and the intermediate knuckle 40 is placed in a socket 12 integral with said fixed knuckle 20. This socket 12 has a flat 13 on its external face.

De même, l'axe 15 est placé dans une douille 16 solidaire en rotation du charnon mobile 30. Cette douille 16 comporte, sur sa face externe, un méplat 17.Similarly, the axis 15 is placed in a sleeve 16 integral in rotation of the movable knuckle 30. This socket 16 comprises, on its external face, a flat 17.

Comme représenté sur les Figs. 3 et 4, la charnière 10 est également pourvue d'un organe de blocage 50 coopérant alternativement avec l'un des méplats 13 et 17 desdites douilles 12 et 16 pour permettre successivement le pivotement du charnon mobile 30 autour de l'axe 15, puis le pivotement de l'ensemble constitué par le charnon intermédiaire 40 et le charnon mobile 30 autour de l'axe 11 du charnon fixe 20 lors de l'ouverture de la porte arrière 2 et inversement lors de la fermeture de cette porte arrière 2, comme on le verra ultérieurement.As shown in Figs. 3 and 4, the hinge 10 is also provided with a blocking member 50 cooperating alternately with one flats 13 and 17 of said sockets 12 and 16 to allow successively the pivoting of the movable knuckle 30 around the axis 15, then the pivoting of the assembly constituted by the intermediate knuckle 40 and the movable knuckle 30 around of the axis 11 of the fixed knuckle 20 when the rear door 2 is opened and vice versa when closing this rear door 2, as will be seen later.

L'organe de blocage 50 est formé par une biellette 51 qui est, comme représentée sur les Figs. 3 et 4, en appui sur le flasque supérieur 42 du charnon intermédiaire 40 et disposée entre les douilles 12 et 16.The blocking member 50 is formed by a link 51 which is, as shown in Figs. 3 and 4, pressing on the upper flange 42 of the intermediate knuckle 40 and disposed between the sockets 12 and 16.

La biellette 51 comporte, à son extrémité disposée en regard de la douille 12 de l'axe 11, une fourche 52 de positionnement sur ladite douille 12 et, à son extrémité en regard de la douille 16 de l'axe 15, une fourche 53 de positionnement sur ladite douille 16.The link 51 comprises, at its end disposed opposite the bush 12 of the axis 11, a fork 52 for positioning on said bush 12 and, at its end opposite the bush 16 of the axis 15, a positioning fork 53 on said socket 16.

Ainsi, la biellette 51 est maintenue en position, d'une part, par le flasque supérieur 42 du charnon intermédiaire 40 et les flasques 22 et 32 respectivement du charnon fixe 20 et du charnon mobile 30 et, d'autre part, par les douilles 12 et 16 respectivement des axes 11 et 15.Thus, the link 51 is held in position, on the one hand, by the upper flange 42 of the intermediate knuckle 40 and the flanges 22 and 32 respectively fixed knuckle 20 and movable knuckle 30 and, on the other hand, by sockets 12 and 16 respectively of axes 11 and 15.

Selon une variante, la biellette 51 peut être disposée au-dessous du flasque inférieur 43 du charnon intermédiaire 40. Dans ce cas, la biellette 51 est maintenue par le flasque 23 du charnon fixe 20 et le flasque 33 du charnon mobile 30.According to a variant, the link 51 can be arranged below of the lower flange 43 of the intermediate knuckle 40. In this case, the link 51 is held by the flange 23 of the fixed knuckle 20 and the flange 33 of the knuckle mobile 30.

Comme représenté à la Fig. 4, la largeur entre les faces internes des deux branches de chaque fourche 52 et 53 est sensiblement égale au diamètre externe des douilles 12 et 16 et la longueur de la biellette 51 entre les fonds des deux fourches 52 et 53 est sensiblement égale à la distance séparant un méplat de l'une des douilles avec une portion cylindrique de l'autre desdites douilles.As shown in Fig. 4, the width between the internal faces of the two branches of each fork 52 and 53 is substantially equal to the diameter outside of the sockets 12 and 16 and the length of the link 51 between the bottoms of the two forks 52 and 53 is substantially equal to the distance between a flat of one of the sockets with a cylindrical portion of the other of said sockets.

En position de fermeture de la porte arrière 2 comme représentée à la Fig. 4, le méplat 13 de la douille 12 du charnon fixe 20 est en contact avec le fond de la fourche 52 de la biellette 51 et le méplat 17 de la douille 16 du charnon mobile 30 est disposé à l'extérieur- de la fourche 53 de ladite biellette 51 et s'étend parallèlement au méplat 13 de la douille 12 dudit charnon fixe 20. In the closed position of the rear door 2 as shown in Fig. 4, the flat 13 of the socket 12 of the fixed knuckle 20 is in contact with the bottom of the fork 52 of the link 51 and the flat 17 of the socket 16 of the movable knuckle 30 is disposed outside of the fork 53 of said link 51 and extends parallel to the flat 13 of the socket 12 of said fixed knuckle 20.

Dans cette position, la douille 12 ainsi que le charnon intermédiaire 20 sont bloqués par la fourche 52 de la biellette 51 qui est en appui sur le méplat 13 de ladite douille 12.In this position, the bush 12 and the intermediate knuckle 20 are blocked by the fork 52 of the link 51 which is supported on the flat 13 of said socket 12.

Par contre, la douille 16 et le charnon mobile 30 peuvent être déplacés en rotation étant donné que la portion cylindrique de la douille 16 se trouve à l'intérieur de la fourche 53 de la biellette 51.On the other hand, the sleeve 16 and the movable knuckle 30 can be moved in rotation since the cylindrical portion of the sleeve 16 is found inside the fork 53 of the link 51.

Au cours de l'ouverture de la porte arrière 2, le charnon mobile 30 pivote autour de l'axe 15 en entraínant la douille 16 qui tourne à l'intérieur de la fourche 53 de la biellette 51, comme représenté à la Fig. 6.During the opening of the rear door 2, the movable knuckle 30 pivots around the axis 15 by driving the socket 16 which rotates inside the fork 53 of the link 51, as shown in FIG. 6.

La porte arrière 2 ainsi que le charnon mobile 30 pivotent entre une première position dans laquelle cette porte arrière 2 est fermée et une seconde position d'ouverture de cette porte arrière selon un angle d'environ de 180°, comme représenté à la Fig. 7.The rear door 2 and the movable knuckle 30 pivot between a first position in which this rear door 2 is closed and a second open position of this rear door at an angle of approximately 180 °, as shown in Fig. 7.

Dans cette position d'ouverture à 180°, le méplat 17 de la douille 16 solidaire du charnon mobile 30 vient en contact avec le fond de la fourche 53 de la biellette 51. Les deux méplats 13 et 17 sont donc opposés l'un par rapport à l'autre et la distance séparant ces deux méplats est supérieure à la distance séparant les fonds des deux fourches 52 et 53 de cette biellette 51 si bien qu'un jeu est ainsi créé entre ces deux méplats 13 et 17 et les deux fonds des fourches 52 et 53 de cette biellette 51.In this position of 180 ° opening, the flat 17 of the sleeve 16 secured to the movable knuckle 30 comes into contact with the bottom of the fork 53 of the link 51. The two flats 13 and 17 are therefore opposite one with respect to the other and the distance separating these two flats is greater than the distance separating the bottoms of the two forks 52 and 53 of this link 51 so that a set is thus created between these two flats 13 and 17 and the two ends of the forks 52 and 53 of this link 51.

Le charnon mobile 20 étant en butée contre le charnon intermédiaire 40, si bien qu'au cours du pivotement de la porte arrière 2 de cette position d'ouverture à 180° jusqu'à la position d'ouverture maximale contre le côté de la caisse du véhicule automobile, comme représentée à la Fig. 8, l'ensemble constitué par ce charnon mobile 30 et ce charnon fixe 40 pivote autour de l'axe 11 du fait du jeu créé entre les méplats 13 et 17 des douilles 12 et 16 et les fonds des fourches 52 et 53 de la biellette 51.The movable knuckle 20 being in abutment against the intermediate knuckle 40, so that during the pivoting of the rear door 2 from this position 180 ° opening to the maximum opening position against the side of the body of the motor vehicle, as shown in FIG. 8, the assembly constituted by this movable knuckle 30 and this fixed knuckle 40 pivots about the axis 11 of the made of the game created between the flats 13 and 17 of the sockets 12 and 16 and the bottoms of the forks 52 and 53 of the link 51.

Au cours de la fermeture de la porte arrière 2, les mouvements inverses sont réalisés.During the closing of the rear door 2, the movements inverses are made.

Grâce à cette disposition, la biellette est maintenue sur le flasque du charnon intermédiaire sans aucun organe de fixation et coulisse sur ce flasque au cours de l'ouverture ou de la fermeture de la porte arrière en coopérant alternativement avec l'un des méplats aménagés sur les douilles des axes de pivotement du charnon mobile et du charnon intermédiaire pour permettre une ouverture de cette porte jusqu'à une position maximale contre la paroi latérale de la caisse de véhicule automobile.Thanks to this arrangement, the link is held on the flange of the intermediate knuckle without any fixing member and slides on this flange during the opening or closing of the rear door by cooperating alternately with one of the flats fitted on the bushes of the axes of pivoting of the movable knuckle and the intermediate knuckle to allow opening of this door to a maximum position against the side wall of the motor vehicle body.
