Ainsi, le bras 62 est fixé en translation suivant l'axe P à la branche libre 52.The roller holder 48 is connected to the support 44 in a translationally mobile manner in a direction T extending perpendicular to the leaf plane V, thus parallel to the sliding plane. However, the roller holder 48 is fixed relative to the support 44 in the other directions and in rotation. For this purpose, the free branch 52 comprises a rectilinear slot 68 extending in the direction T. Two lugs 70 fixed to the end of the arm 62, opposite the end carrying the rollers 64, 66, extend in this direction. slot 68. A locking plate 71 is attached to the end of the lugs 70 on the side of the arm 52 opposite the arm 62. In other words, the arm 52 is sandwiched between the arm 62 and the plate 71. This plate 71 has a width greater than the width of the slot 68. Thus, the arm 62 is fixed in translation along the axis P to the free branch 52.

Le porte-galets 48 est ainsi uniquement mobile suivant la direction T entre une position sortie (Figure 3), dans laquelle il se trouve lorsque la porte est ouverte, et une position rétractée (Figures 2 et 4), dans laquelle il se trouve lorsque la porte est fermée.The roller carrier 48 is thus only movable in the direction T between an extended position (FIG. 3), in which it is located when the door is open, and a retracted position (FIGS. 2 and 4), in which it is located when the door is closed.

La longueur de la partie courante 32 du rail supérieur 22 est supérieure à la longueur de la partie courante du rail inférieur 24 d'une distance D (Figure 1). Cette distance D est égale à la distance D entre les axes A1 et A2 lorsqu'ils sont parallèles l'un à l'autre (Figure 3). Ainsi, le rail supérieur s'étend au-dessus d'une roue arrière 72 du véhicule.The length of the current portion 32 of the upper rail 22 is greater than the length of the running portion of the lower rail 24 by a distance D (Figure 1). This distance D is equal to the distance D between the axes A1 and A2 when they are parallel to each other (FIG. 3). Thus, the upper rail extends above a rear wheel 72 of the vehicle.

Il est à noter que le chariot 28, au moyen des galets porteur 56, 64, maintient le vantail 10 en translation selon une direction verticale, donc parallèle à l'axe P, et perpendiculairement à la direction C, tandis que les galets de guidage 58, 66 assurent un maintien du vantail 10 suivant la direction T.It should be noted that the carriage 28, by means of the carrier rollers 56, 64, keeps the leaf 10 in translation in a vertical direction, therefore parallel to the axis P, and perpendicular to the direction C, while the guide rollers 58, 66 ensure a retention of the leaf 10 along the direction T.

De plus, le chariot 28, au moyen des galets 56, 58, 64, 66, maintient le vantail 10 fixe en rotation autour de l'axe P.In addition, the carriage 28, by means of the rollers 56, 58, 64, 66, keeps the leaf 10 fixed in rotation around the axis P.

Comme il ressort des Figures 2 et 3, les galets de guidage 58, 66 sont décalés vers la position de fermeture par rapport aux galets porteurs 56, 64 pour empêcher un blocage des chariots dans le rail.As shown in Figures 2 and 3, the guide rollers 58, 66 are shifted towards the closed position relative to the carrier rollers 56, 64 to prevent locking of the carriages in the rail.

Le rail inférieur 24 et le chariot inférieur 30 sont connus en soi. Le rail inférieur 24 s'étend parallèlement au rail supérieur 22 et a une section transversale identique à celui-ci.The lower rail 24 and the lower carriage 30 are known per se. The lower rail 24 extends parallel to the upper rail 22 and has a cross section identical thereto.

Le chariot inférieur 30 comprend un support inférieur et un porte-galets inférieur analogues aux support 44 et au porte-galets 46 du chariot supérieur 28. Comme différence, le porte-galets inférieur est mobile le long de son axe d'articulation P entre deux butées et est sollicité axialement par un ressort.The lower carriage 30 comprises a lower support and a lower roller carrier similar to the supports 44 and the roller carrier 46 of the upper carriage 28. As a difference, the lower roller carrier is movable along its hinge axis P between two stops and is biased axially by a spring.

De plus, le chariot inférieur 30 ne comporte pas de porte-galets 48.In addition, the lower carriage 30 does not have rollers 48.

Le chariot inférieur 30 maintient le vantail 10 en translation suivant l'axe P et dans la direction T perpendiculaire au plan V. En outre, ce chariot 30 maintient le vantail 10 également fixe en rotation autour d'un axe parallèle à l'axe P et autour d'une direction perpendiculaire au plan V.The lower carriage 30 holds the leaf 10 in translation along the axis P and in the direction T perpendicular to the plane V. In addition, this carriage 30 holds the leaf 10 also fixed in rotation around an axis parallel to the axis P and around a direction perpendicular to the plane V.

La porte selon l'invention fonctionne de la manière suivante.The door according to the invention operates as follows.

Initialement, la porte est dans sa position fermée, telle que montrée sur les Figures 1, 2 et 4. Le porte-galets 28 est positionné de telle sorte que l'axe A1 est incliné par rapport au plan V et les galets 56, 58 se trouvent dans la partie coudée 36.Initially, the door is in its closed position, as shown in Figures 1, 2 and 4. The roller holder 28 is positioned such that the axis A1 is inclined with respect to the plane V and the rollers 56, 58 are in the bent portion 36.

Le porte-galets 48 est dans sa position rétractée.The roller holder 48 is in its retracted position.

Le galet porteur du chariot inférieur 30 se trouve dans la partie coudée 38 du rail inférieur.The carrier roller of the lower carriage 30 is in the bent portion 38 of the lower rail.

Lors de l'ouverture de la porte, le porte-galets 46 bascule de telle sorte que les deux axes A1, A2 soient parallèles l'un à l'autre et simultanément le porte-galets 48 coulisse vers sa position sortie. Le porte-galets du chariot 30 effectue un mouvement qui est identique à celui du porte-galets 46 et qui est synchrone avec celui-ci.When opening the door, the roller holder 46 tilts so that the two axes A1, A2 are parallel to each other and simultaneously the roller holder 48 slides to its extended position. The carrier of the carriage 30 carries a movement which is identical to that of the roller carrier 46 and which is synchronous therewith.

Le vantail 10 effectue donc un déplacement en translation suivant la direction T vers l'extérieur de la caisse pendant lequel le plan V reste toujours parallèle au plan V lorsque la porte est dans sa position fermée.Leaf 10 thus performs a displacement in translation in the direction T towards the outside of the box during which the plane V remains always parallel to the plane V when the door is in its closed position.

Grâce à l'agencement de deux galets porteurs et de guidage disposés dans un même rail 22, la porte coulissante ne nécessite que deux rails de guidage 22, 24, ce qui rend la fabrication et le montage économique. De plus, la porte selon l'invention conduit à un aspect esthétique du véhicule, étant donné que les rails 22, 24 ne sont pas visibles lorsque la porte est à l'état fermé.Thanks to the arrangement of two support and guide rollers arranged in the same rail 22, the sliding door requires only two guide rails 22, 24, which makes the manufacture and assembly economical. In addition, the door according to the invention leads to an aesthetic appearance of the vehicle, since the rails 22, 24 are not visible when the door is in the closed state.

En variante, les positions des ensembles de coulisse 12, 14 sont inversées, c'est-à-dire le rail 22 et le chariot 28 sont disposés à l'extrémité inférieure du vantail 10, tandis que le rail 24 et le chariot 30 sont disposés à l'extrémité supérieure du vantail 10.In a variant, the positions of the slide assemblies 12, 14 are reversed, that is to say the rail 22 and the carriage 28 are arranged at the lower end of the leaf 10, while the rail 24 and the carriage 30 are arranged at the upper end of the leaf 10.
