Description

ESSUIE-GLACE POUR L'ESSUYAGE D'UN PARE-BRISE PANORAMIQUE POURVU DE SURFACES LATERALES, SYSTEME WIPER FOR WIPING A PANORAMIC WINDSCREEN WITH SIDE SURFACES, SYSTEM
D'ESSUYAGE CORRESPONDANT ET SON UTILISATION L'invention concerne un essuie-glace pour l'essuyage d'un pare- brise panoramique pourvu de surfaces latérales, un système d'essuyage pourvu tel essuie-glace, et son utilisation.The invention relates to a wiper for wiping a panoramic windshield provided with side surfaces, a wiper system provided with such windshield wiper, and its use.
Les pare-brise panoramiques sont composés de trois surfaces : une surface frontale et deux surfaces latérales habituellement séparées les unes des autres et assemblées à l'aide d'éléments de structure tels que des montants. Ces montants agissent comme des déflecteurs qui décollent les filets d'air de la surface frontale, ces derniers entraînant avec eux l'eau et les salissures. Le même problème se pose pour les pare-brise panoramiques dont les surfaces latérales et frontale sont reliées par une surface de raccordement. Cette dernière peut être essuyée grâce à un dispositif permettant de corriger l'angle d'attaque de la lame d'essuyage, mais un tel dispositif sophistiqué ne permet pas de nettoyer la surface latérale.Panoramic windshields are composed of three surfaces: a front surface and two side surfaces usually separated from each other and assembled using structural elements such as uprights. These amounts act as deflectors that take off the air streams from the front surface, the latter carrying with them water and dirt. The same problem arises for panoramic windscreens whose lateral and frontal surfaces are connected by a connecting surface. The latter can be wiped with a device for correcting the angle of attack of the wiper blade, but such a sophisticated device does not clean the side surface.
La surface frontale est nettoyée de manière classique par essuyage au moyen d'une lame racleuse en caoutchouc montée sur un balai d'essuie-glace. Ce système d'essuyage propulse systématiquement l'eau et les salissures sur les parties latérales, qui seront donc beaucoup plus exposées à une occultation par l'eau et les salissures, réduisant ainsi le champ de vision du conducteur.The front surface is conventionally cleaned by wiping with a rubber scraper blade mounted on a wiper blade. This wiper system systematically propels water and dirt on the side parts, which will be much more exposed to water and dirt concealment, thus reducing the driver's field of vision.
L'objectif de l'invention est de réaliser un dispositif de lavage par projection d'un liquide afin d'augmenter le pourcentage de surface nettoyée du pare-brise panoramique.The object of the invention is to provide a device for washing by spraying a liquid in order to increase the percentage of cleaned surface of the panoramic windshield.
Le document US-3 887 956 décrit un essuie-glace comprenant un bras supportant un balai sur lequel est monté la lame d'essuyage. Le bras comprend des buses de distribution d'un liquide de lavage dirigées vers la surface à nettoyer. Ces buses, alimentées par un conduit situé dans le bras, sont placées sous le bras, à proximité de l'attache de la lame, afin d'envoyer le liquide sur le pare-brise, juste devant la lame. Elles ne permettent donc pas de nettoyer des surfaces distantes de la lame. Le document US 2004/0078916 décrit un bras d'essuie-glace réalisé en matière plastique composite, dans lequel il est prévu un conduit pour un liquide de lavage. Toutefois, ce document ne décrit pas comment nettoyer des surfaces latérales d'un pare-brise panoramique, distantes de la lame.US-3,887,956 discloses a wiper comprising an arm supporting a blade on which is mounted the wiper blade. The arm includes nozzles for dispensing a washing liquid directed to the surface to be cleaned. These nozzles, fed by a duct located in the arm, are placed under the arm, near the attachment of the blade, to send the liquid on the windshield, just in front of the blade. They therefore do not allow to clean distant surfaces of the blade. US 2004/0078916 discloses a wiper arm made of composite plastic material, in which there is provided a conduit for a washing liquid. However, this document does not describe how to clean side surfaces of a panoramic windshield, distant from the blade.
Il existe par ailleurs des systèmes indépendants d'essuyage, comportant des balais d'essuie- glace indépendants, placés sur les côtés du véhicule afin de nettoyer les surfaces latérales d'un pare-brise. Ces systèmes posent toutefois le problème de l'intégration du moteur d'entraînement du balai d'essuie-glace et d'un coût élevé.There are also independent wiper systems, with independent wiper blades, placed on the sides of the vehicle to clean the side surfaces of a windshield. These systems, however, pose the problem of integrating the drive motor of the wiper blade and a high cost.
L'invention vise à pallier ces inconvénients en proposant un essuie-glace pourvu d'un dispositif de lavage permettant de nettoyer les surfaces latérales d'un pare-brise panoramique, et qui soit économique.The invention aims to overcome these disadvantages by providing a wiper provided with a washing device for cleaning the side surfaces of a panoramic windshield, and which is economical.
A cet effet, l'objet de l'invention concerne un essuie-glace pour l'essuyage d'un pare-brise panoramique pourvu de surfaces latérales, comprenant un bras destiné à être monté mobile sur un véhicule automobile, et un balai formé d'une monture supportant une lame d'essuyage, la monture étant pourvue d'une attache apte à coopérer avec le bras, caractérisé en ce qu'il est pourvu d'un dispositif de lavage destiné à être alimenté en liquide au moyen d'une pompe reliée à un réservoir de liquide de lavage, la pompe et le réservoir étant situés sur le véhicule, le dispositif étant apte à envoyer des jets de liquide de lavage sous pression à distance de la lame d'essuyage, en direction d'une face latérale d'un pare-brise panoramique. L'impact des jets de liquide de lavage sous pression sur la surface latérale permet de nettoyer les salissures se trouvant sur cette surface pour un coût nettement inférieur à un système indépendant d'essuie-glace. Avantageusement, le dispositif de lavage comprend une rampe portant au moins deux gicleurs pour l'envoi des jets de liquide sous pression, et un conduit d'alimentation de la rampe en liquide de lavage, chaque gicleur étant orienté de manière à diriger du liquide sous pression en direction d'une zone prédéterminée de la £εtce latérale du pare-brise panoramique lorsque l'essuie-glace est situé à proximité de ladite surface latérale.To this end, the object of the invention relates to a wiper for wiping a panoramic windshield provided with side surfaces, comprising an arm intended to be mounted to move on a motor vehicle, and a broom formed of a frame supporting a wiper blade, the mount being provided with a clip adapted to cooperate with the arm, characterized in that it is provided with a washing device intended to be supplied with liquid by means of a pump connected to a tank of washing liquid, the pump and the tank being located on the vehicle, the device being able to send jets of pressurized washing liquid away from the wiper blade, towards one side side of a panoramic windshield. The impact of the pressurized wash liquid jets on the side surface makes it possible to clean the soils on this surface at a cost significantly lower than an independent windshield wiper system. Advantageously, the washing device comprises a ramp carrying at least two nozzles for sending the pressurized liquid jets, and a supply duct of the ramp in washing liquid, each nozzle being oriented so as to direct the liquid under pressure towards a predetermined area of the lateral side of the panoramic windshield when the wiper is located near said lateral surface.
Avantageusement, la rampe du dispositif de lavage est fixée sur le bras du balai, du côté de la surface à nettoyer. En variante, la rampe et ses gicleurs sont fixés à la monture du balai, du côté de la surface à nettoyer. Ces agencements présentent l'avantage de ne pas nécessiter de modification des essuie-glaces existants. Dans un mode de réalisation particulier, la rampe et ses gicleurs sont incorporés à l'intérieur de la monture du balai, ladite monture étant pourvue d'orifices de sortie des gicleurs situés du côté de la surface à nettoyer. De préférence, les gicleurs sont orientés de sorte que la surface totale des différentes zones correspond au moins à la moitié de la surface de la face latérale du pare-brise panoramique.Advantageously, the ramp of the washing device is fixed on the arm of the blade, on the side of the surface to be cleaned. Alternatively, the ramp and its nozzles are attached to the frame of the blade on the side of the surface to be cleaned. These arrangements have the advantage of not requiring modification of the existing wipers. In a particular embodiment, the ramp and its nozzles are incorporated inside the frame of the blade, said mount being provided with nozzle outlets located on the side of the surface to be cleaned. Preferably, the nozzles are oriented so that the total area of the different areas corresponds to at least half of the surface of the side face of the panoramic windshield.
L'invention concerne également un système d'essuyage d'un pare- brise panoramique comportant au moins un essuie-glace selon l'invention actionné par un moteur commandé par un dispositif de commande, un réservoir de liquide et une pompe, dans lequel la pompe est reliée au dispositif de commande, et le dispositif de commande est conçu de manière à déclencher la pompe lorsque l'essuie-glace est proche de la surface latérale du pare-brise panoramique à nettoyer afin d'envoyer des jets de liquide de lavage en direction de la surface à nettoyer.The invention also relates to a wiper system for a panoramic windscreen comprising at least one windscreen wiper according to the invention actuated by a motor controlled by a control device, a liquid reservoir and a pump, in which the pump is connected to the control device, and the control device is designed to trigger the pump when the wiper is close to the side surface of the panoramic windshield to be cleaned in order to send jets of washing liquid towards the surface to be cleaned.
L'invention concerne également l'utilisation d'un système d'essuyage selon l'invention pour l'essuyage d'une surface latérale d'un pare-brise panoramique, dans laquelle le dispositif de commande déclenche l'envoi des jets de liquide lorsque l'essuie-glace est proche de la surface latérale du pare-brise panoramique à nettoyer.The invention also relates to the use of a wiper system according to the invention for wiping a side surface of a panoramic windscreen, in which the control device triggers the sending of the jets of liquid when the wiper is close to the side surface of the panoramic windshield to be cleaned.
Avantageusement, cette utilisation concerne le nettoyage d'un pare-brise panoramique recouvert d'une couche photo- catalytique. Une telle couche photo- catalytique permet d'achever le nettoyage de la surface latérale par photo catalyse obtenue par l'action combinée des rayons ultra-violets du soleil et de la couche photo- catalytique.Advantageously, this use relates to the cleaning of a panoramic windshield covered with a photocatalytic layer. Such a photocatalytic layer makes it possible to complete the cleaning of the lateral surface by photo-catalysis obtained by the combined action of the ultraviolet rays of the sun and the photocatalytic layer.
L'invention est maintenant décrite en référence aux dessins annexés, non limitatifs, dans lesquels : la figure 1 est une représentation schématique partielle en perspective d'un pare-brise panoramique essuyé par un essuie-glace selon l'invention ; la figure 2 est une vue agrandie en perspective d'un essuie-glace selon l'invention ; la figure 3 est une vue en coupe transversale d'un autre mode de réalisation d'un essuie-glace selon l'invention, au niveau de la rampe du dispositif de lavage. La figure 1 représente un pare-brise panoramique 1 composé de trois surfaces : une surface 2 frontale et deux surfaces 3 latérales (dont une est représentée en pointillés) qui s'étendent sensiblement perpendiculairement à la surface frontale 2. Les surfaces frontale 2 et latérales 3 sont reliées par une surface de raccordement 4 repérée par des hachures sur la figure 1.The invention is now described with reference to the accompanying non-limiting drawings, in which: FIG. 1 is a partial schematic perspective representation of a panoramic windscreen wiped by a wiper according to the invention; Figure 2 is an enlarged perspective view of a windscreen wiper according to the invention; Figure 3 is a cross-sectional view of another embodiment of a windscreen wiper according to the invention, at the level of the ramp of the washing device. FIG. 1 represents a panoramic windshield 1 composed of three surfaces: a front surface 2 and two lateral surfaces 3 (one of which is shown in dotted lines) which extend substantially perpendicularly to the front surface 2. The front and side surfaces 2 3 are connected by a connecting surface 4 marked with hatching in FIG.
L'essuyage de la surface frontale 2 du pare-brise est réalisé au moyen d'un essuie-glace 5 selon l'invention faisant partie d'un système d'essuyage. Cet essuie-glace comprend un bras 6 destiné à être monté mobile sur un véhicule automobile, et un balai 7. Le balai est formé de manière classique d'une monture supportant une lame d'essuyage, pourvue d'une attache apte à coopérer avec le bras, et sa structure ne sera donc pas détaillée. Il s'agit par exemple d'un balai à palonniers ou d'un balai plat.The wiping of the front surface 2 of the windshield is achieved by means of a windscreen wiper 5 according to the invention forming part of a wiping system. This wiper comprises an arm 6 intended to be mounted on a motor vehicle, and a broom 7. The broom is conventionally formed of a frame supporting a wiper blade, provided with a clip adapted to cooperate with the arm, and its structure will not be detailed. This is for example a broom or a flat broom.
Le système d'essuyage comprend en outre un moteur 8 d'actionnement de l'essuie-glace commandé par un dispositif de commande 9, ainsi qu'un réservoir 10 de liquide de lavage et une pompe 11. Le moteur, le dispositif de commande, le réservoir et la pompe sont montés sur le véhicule.The wiper system further comprises a motor 8 for actuating the wiper controlled by a control device 9, as well as a reservoir 10 of washing liquid and a pump 11. The motor, the control device , the tank and the pump are mounted on the vehicle.
L'essuie-glace 5 selon l'invention est pourvu d'un dispositif de lavage destiné à être alimenté en liquide au moyen de la pompe 11 reliée au réservoir 10 de liquide de lavage, le dispositif étant apte à envoyer des jets de liquide de lavage sous pression à distance de la lame d'essuyage, en direction d'une face latérale 3 du pare-brise panoramique.The windscreen wiper 5 according to the invention is provided with a washing device intended to be supplied with liquid by means of the pump 11 connected to the reservoir 10 of washing liquid, the device being able to send jets of liquid of pressure washing away from the wiper blade, towards a side face 3 of the panoramic windshield.
Le dispositif de lavage comprend une rampe 12 portant plusieurs gicleurs 13 pour l'envoi de jets de liquide sous pression, et un conduit d'alimentation 14 de la rampe en liquide de lavage, relié au réservoir de liquide 10 par l'intermédiaire de la pompe 11. Dans l'exemple représenté figure 2, la rampe du dispositif de lavage est montée sur le bras 6 de l'essuie-glace du côté de la surface latérale 3 à nettoyer, par exemple au moyen d'agrafes 15 ou de clips. La rampe s'étend le long du bras, parallèlement à ce dernier. En variante, la rampe et les gicleurs peuvent être intégrés à la monture du balai. Ainsi, la figure 3 représente un balai 7\ du type balai plat, comprenant une lame d'essuyage 16 supportée par une monture 17 en matière plastique souple dans laquelle est placée une vertèbre 18 souple capable d'absorber les variations de galbe imposées par la courbure du pare-brise à essuyer. La lame d'essuyage 16 est enfilée dans un profil réalisé dans la monture 17. La rampe 12', sous la forme d'une conduite, est noyée dans le matériau de la monture 17. La rampeThe washing device comprises a ramp 12 carrying several nozzles 13 for sending jets of liquid under pressure, and a supply duct 14 of the ramp in washing liquid, connected to the liquid reservoir 10 via the pump 11. In the example shown in Figure 2, the ramp of the washing device is mounted on the arm 6 of the wiper side of the side surface 3 to be cleaned, for example by means of staples 15 or clips . The ramp extends along the arm, parallel to the latter. In a variant, the ramp and the nozzles can be integrated into the frame of the blade. Thus, Figure 3 shows a broom 7 \ type flat blade, comprising a wiper blade 16 supported by a frame 17 flexible plastic material in which is placed a flexible vertebra 18 capable of absorbing the curve variations imposed by the curvature of the windshield to be wiped. The wiper blade 16 is threaded into a profile made in the frame 17. The ramp 12 ', in the form of a pipe, is embedded in the material of the frame 17. The ramp
12' s'étend suivant la direction longitudinale de la monture, à proximité d'un bord de celle-ci. Cette rampe est reliée à une pluralité de gicleurs 13' débouchant par un orifice 19 de la surface latérale de la monture 17, du côté de la surface à nettoyer. Ainsi, dans ce cas, la rampe est réalisée d'une pièce avec la monture 17 du balai et est intégrée à celle- ci.12 'extends in the longitudinal direction of the frame, near an edge thereof. This ramp is connected to a plurality of nozzles 13 'opening through an orifice 19 of the side surface of the frame 17, on the side of the surface to be cleaned. Thus, in this case, the ramp is made in one piece with the frame 17 of the brush and is integrated therewith.
Pour plus de clarté, seuls trois gicleurs 13 sont représentés sur la figure 1, chaque gicleur 13 étant orienté de manière à diriger du liquide sous pression en direction d'une zone Zl, Z2, Z3 prédéterminée de la £εtce latérale 3 du pare-brise panoramique lorsque l'essuie- glace est situé à proximité de ladite surface latérale 3.For the sake of clarity, only three nozzles 13 are shown in FIG. 1, each nozzle 13 being oriented so as to direct liquid under pressure towards a predetermined zone Z1, Z2, Z3 of the side shell 3 of the cover. panoramic breeze when the windscreen wiper is located near said lateral surface 3.
Plus particulièrement, les gicleurs 13 sont orientés de sorte que la surface totale des différentes zones Zl, Z2, Z3 correspond au moins à la moitié de la surface de la £εtce latérale 3 du pare-brise panoramique. Ainsi, le nombre de gicleurs est choisi en fonction du pourcentage de surface que l'on souhaite nettoyer au moyen des jets sous pression.More particularly, the nozzles 13 are oriented so that the total area of the different zones Z1, Z2, Z3 corresponds to at least half of the surface of the side shell 3 of the panoramic windshield. Thus, the number of nozzles is chosen according to the percentage of surface that it is desired to clean by means of pressurized jets.
Le système de lavage fonctionne de la manière suivante. L'essuyage de la surface frontale 2 se fait de manière habituelle par le va et vient de l'essuie-glace 5 actionné par son moteur 8. L'essuie-glace se déplace ainsi entre une position d'arrêt fixe Pl et une position opposée d'arrêt fixe P2 située à proximité de la surface latérale 3 (voir figure 1). Lorsque le bras d'essuie- glace est dans cette dernière position, le dispositif de commande 9 déclenche la pompe 11, par exemple une pompe haute pression, qui va alimenter la rampe 12 via le conduit 14, et provoquer l'aspersion de la surface latérale 3.The washing system operates as follows. The wiping of the front surface 2 is usually done by the comings and goings of the wiper 5 actuated by its motor 8. The wiper thus moves between a fixed stop position P 1 and a position opposite fixed stop P2 located near the side surface 3 (see Figure 1). When the wiper arm is in the latter position, the control device 9 triggers the pump 11, for example a high-pressure pump, which will supply the ramp 12 via the conduit 14, and cause the surface to be sprinkled lateral 3.
La pression des jets de lavage projetés par les gicleurs, qui dépend de la puissance de la pompe 11, est adaptée en fonction de la distance entre la surface latérale à essuyer et l'essuie-glace, lorsque ce dernier est dans la position P2. De préférence, la pompe 11 n'est déclenchée que lors d'une demande de lavage du pare-brise par le conducteur. Afin de faciliter le nettoyage des surfaces latérales, celles-ci peuvent être recouvertes d'une couche photo- catalytique dont l'action est décrite plus haut. Une telle couche peut en outre être appliquée sur l'ensemble de la surface du pare-brise. The pressure of the jet jets sprayed by the nozzles, which depends on the power of the pump 11, is adapted according to the distance between the side surface to be wiped and the wiper, when the latter is in the P2 position. Preferably, the pump 11 is triggered only during a request for washing the windshield by the driver. In order to facilitate the cleaning of the lateral surfaces, these can be covered with a photo-catalytic layer whose action is described above. Such a layer may further be applied to the entire surface of the windshield.
