Le dispositif, repéré généralement par 1 à la figure 1 , de lavage de la surface vitrée 2 de la lunette arrière d'un véhicule automobile, comporte un chariot 3 guidé dans un rail 4 de façon à pouvoir se déplacer le long de l'arête supérieure 21 de la paroi vitrée 2. Le chariot 3 est entraîné par l'intermédiaire d'un moyen d'entraînement, repérée généralement par 5, constitué d'une crémaillère souple 6 comportant une âme autour de laquelle un fil est enroulé en spirale, qui circule à l'intérieur d'une gaine 7, et qui coopère avec un moyen d'entraînement motorisé 8 comportant une roue dentée 9 s'engrainant sur la crémaillère souple 6 et entraînée par un moteur réducteur 10.The device, generally indicated by 1 in FIG. 1, for washing the glazed surface 2 of the rear window of a motor vehicle, comprises a carriage 3 guided in a rail 4 so as to be able to move along the ridge upper 21 of the glass wall 2. The carriage 3 is driven by means of a drive means, generally marked by 5, consisting of a flexible rack 6 having a core around which a wire is wound in a spiral, which circulates inside a sheath 7, and which cooperates with a motorized drive means 8 comprising a gear 9 engraining on the flexible rack 6 and driven by a reducing motor 10.
Le chariot 3 est relié par l'intermédiaire d'un moyen de liaison hydraulique, repéré généralement par 11 , à une source de liquide de lavage 14.The carriage 3 is connected by means of a hydraulic connection means, generally indicated by 11, to a source of washing liquid 14.
Le liquide de lavage issu de la source 14 et conduit par le moyen de transmission hydraulique 11 jusqu'au chariot 3 peut sortir du chariot 3 sous forme d'un jet de liquide de lavage 100 qui se déplace avec le chariot sur toute la largueur de la paroi vitrée 2.The washing liquid from the source 14 and driven by the hydraulic transmission means 11 to the carriage 3 can exit the carriage 3 in the form of a jet of washing liquid 100 which moves with the carriage over the entire width of the glass wall 2.
Le moyen de liaison hydraulique 11 est constitué d'un tuyau 12 qui circule à l'intérieur d'une gaine de guidage 13 et qui aboutit à un moyen d'enroulement/déroulement 15 qui sera décrit plus en détail ultérieurement. La gaine de guidage 13 s'étend depuis le moyen d'enroulement/déroulement jusqu'à l'entrée du rail de guidage 4. Une extrémité du tuyau souple 11 est liée au chariot 3 et l'autre extrémité peut s'enrouler sur l'enrouleur/ dérouleur 15. La longueur du tuyau est telle qu'il permet un mouvement complet du chariot 3 depuis une extrémité du rail de guidage jusqu'à l'autre extrémité du rail de guidage.The hydraulic connection means 11 consists of a pipe 12 which circulates inside a guide sheath 13 and which leads to a winding / unwinding means 15 which will be described in more detail later. The guide sheath 13 extends from the winding / unwinding means to the inlet of the guide rail 4. One end of the flexible hose 11 is connected to the carriage 3 and the other end can be wound on the The hose length is such that it allows complete movement of the carriage 3 from one end of the guide rail to the other end of the guide rail.
On comprend que lorsque le chariot 3 est à l'extrémité du rail de guidage qui est opposé à l'extrémité par laquelle arrive le tuyau, la longueur de tuyau entre le chariot et l'enrouleur/ dérouleur est maximale, alors que, lorsque le chariot est à l'extrémité du rail de guidage qui se trouve du côté de l'arrivée du tuyau, la longueur du tuyau entre le chariot et le dispositif d'enroulage/ déroulage est minimale.It is understood that when the carriage 3 is at the end of the guide rail which is opposite to the end through which the pipe arrives, the length of pipe between the carriage and the reel / unwinder is maximum, whereas, when the carriage is at the end of the guide rail which is on the side of the arrival of the pipe, the length of the pipe between the carriage and the winding / unwinding device is minimal.
La différence de longueur entre ces deux positions du tuyau est absorbée par l'enroulement ou le déroulement du tuyau sur le moyen d'enroulement/déroulement 15. Ce moyen d'enroulement/déroulement dispose d'un moyen de rappel élastique permettant d'enrouler le tuyau lorsque le chariot fait un mouvement tendant à raccourcir la longueur de tuyau nécessaire. Comme on le voit sur la figure 2, le chariot 3 comporte un patin de maintien 31 et un patin de guidage et de réception du liquide de lavage 32 qui glissent respectivement à l'intérieur d'une gorge de maintien 41 d'une part, et d'une gorge de guidage 42 d'autre part, prévues dans le rail de guidage 4. Le patin de guidage et de réception de liquide de lavage 32 comporte une cavité 34 en communication par l'intermédiaire d'un canal 35 avec une buse 37 située à l'extrémité 36 d'un bras 33 du chariot, agencé pour que la buse 37 soit à proximité de la surface vitrée 2.The difference in length between these two positions of the pipe is absorbed by the winding or unwinding of the pipe on the winding / unwinding means 15. This winding / unwinding means has an elastic return means for winding up the pipe when the carriage makes a movement tending to shorten the necessary length of pipe. As can be seen in FIG. 2, the carriage 3 comprises a holding pad 31 and a guide and receiving pad of the washing liquid 32 which slide respectively inside a holding groove 41 on the one hand, and a guide groove 42 on the other hand, provided in the guide rail 4. The guide and washing liquid receiving pad 32 comprises a cavity 34 in communication via a channel 35 with a nozzle 37 located at the end 36 of an arm 33 of the carriage, arranged so that the nozzle 37 is close to the glass surface 2.
Comme on peut le voir sur la figure 3, le patin 32 de guidage et de réception de liquide de lavage, qui glisse à l'intérieur de la gorge 42 du rail 4, est relié à l'extrémité 12A du tuyau souple 12, de telle sorte que le tuyau 12 puisse alimenter en liquide de lavage la cavité 34.As can be seen in FIG. 3, the pad 32 for guiding and receiving washing liquid, which slides inside the groove 42 of the rail 4, is connected to the end 12A of the hose 12, so that the pipe 12 can supply the cavity 34 with washing liquid.
La gaine de guidage 13 est fixée par son extrémité 13A à l'extrémité de la gorge 42 du rail de guidage 4. Ainsi, lorsque le chariot 3 se déplace, la gaine 13 reste immobile alors que le tuyau souple 12 peut glisser à l'intérieur de la gaine et de la gorge de guidage 42, et ainsi suivre le mouvement du chariot 3.The guide sheath 13 is fixed by its end 13A to the end of the groove 42 of the guide rail 4. Thus, when the carriage 3 moves, the sheath 13 remains stationary while the flexible pipe 12 can slide to the inside the sheath and the guide groove 42, and thus follow the movement of the carriage 3.
Le moyen d'enroulement/déroulement, repéré généralement par 15 à la figure 4, comporte un arbre vertical 150 creux autour duquel vient s'enrouler le tuyau 12.The winding / unwinding means, generally indicated by 15 in FIG. 4, comprises a hollow vertical shaft 150 around which the pipe 12 is wound.
Par une de ses extrémités 12B, le tuyau 12 pénètre à l'intérieur de l'axe central de l'arbre creux 150 pour être relié par un joint tournant 152 à un tube de liaison 153 avec la source de liquide de lavage 14. La source de liquide de lavage comporte notamment une pompe comprenant par exemple un rotor 140.By one of its ends 12B, the pipe 12 penetrates inside the central axis of the hollow shaft 150 to be connected by a rotary joint 152 to a connecting tube 153 with the source of washing liquid 14. The washing fluid source comprises in particular a pump comprising for example a rotor 140.
L'arbre 150, qui est monté sur un support fixe 151 , est relié au support fixe 151 par un ressort spiral 154 fonctionnant en torsion, de telle sorte que le ressort est au repos lorsque le tuyau 12 est complètement enroulé autour de l'arbre 150. Lorsque le tuyau 12 est déroulé, le ressort 154 est tendu et exerce un effort de rappel en rotation sur l'arbre 150, qui permet d'enrouler le tuyau 12 autour de l'arbre lorsque la traction sur le tuyau est relâchée.The shaft 150, which is mounted on a fixed support 151, is connected to the fixed support 151 by a spiral spring 154 operating in torsion, so that the spring is at rest when the pipe 12 is completely wound around the shaft 150. When the pipe 12 is unwound, the spring 154 is stretched and exerts a restoring force in rotation on the shaft 150, which allows to wind the pipe 12 around the shaft when the pull on the pipe is released.
Comme représenté plus en détail en coupe à la figure 5, la liaison du tube 12 avec le tube de liaison 153 par l'intermédiaire du joint tournant 152 comprend un embout 155 fixé à l'extrémité du tube 12, dont une extrémité 156 pénètre à l'intérieur d'un embout 157 fixé à l'extrémité du tube de liaison 153. Dans la zone où l'extrémité d'embout 155 pénètre à l'intérieur de l'embout 157, un joint torique 158 assure l'étanchéité et permet la rotation de l'embout 155 par rapport à l'embout 157.As shown in more detail in section in FIG. 5, the connection of the tube 12 with the connecting tube 153 via the rotary joint 152 comprises a nozzle 155 fixed to the end of the tube 12, one end 156 of which penetrates to the inside of a tip 157 fixed to the end of the connecting tube 153. In the area where the tip end 155 penetrates inside the tip 157, an O-ring 158 seals and allows rotation of the endpiece 155 relative to the endpiece 157.
Le dispositif tel qu'il vient d'être décrit à l'avantage d'utiliser un tuyau qui peut s'enrouler et se dérouler sur un dispositif exerçant une force de rappel sur le tuyau, ce qui facilite le mouvement du chariot 3. En effet, le mouvement qui tend à éloigner le chariot de l'enrouleur/ dérouleur 15 résulte d'un effort de traction exercé par la crémaillère souple 6, alors que le mouvement en sens inverse du chariot peut être facilité par l'effort de traction exercé par l'intermédiaire du tuyau souple 12 résultant de la tension du ressort de rappel de l'enrouleur/ dérouleur 15.The device as just described to the advantage of using a hose that can wind and unwind on a device exerting a restoring force on the pipe, which facilitates the movement of the carriage 3. Indeed, the movement that tends to move the carriage from the reel / unwinder 15 results from a tensile force exerted by the flexible rack 6, while the movement in the opposite direction of the carriage can be facilitated by the tensile force exerted via the hose 12 resulting from the tension of the return spring of the reel / unwinder 15.
Le dispositif qui vient d'être décrit a été décrit avec un moyen pour déplacer le jet d'arrosage constitué d'un chariot se déplaçant le long de la vitre comportant une buse qui émet un jet d'arrosage de liquide de lavage.The device which has just been described has been described with a means for moving the jet consisting of a spray jet moving along the window having a nozzle that emits a spray jet of washing liquid.
Mais d'autres dispositifs peuvent être envisagés. En particulier, ces dispositifs peuvent comprendre un chariot se déplaçant le long d'une arête supérieure de la surface vitrée à arroser, dans un rail de guidage comportant des buses disposés sur sa longueur et qui sont alimentés lorsque le chariot arrive en regard de chacune d'elles.But other devices can be envisaged.
