Description
DEFLECTEUR POUR ESSUIE-GLACE. WINDSCREEN WIPER DEFLECTOR.
L'invention concerne un déflecteur pour essuieglace notamment de véhicule automobile. The invention relates to a deflector for a windscreen wiper, in particular for a motor vehicle.
Il est connu de rapprocher le plus possible le bord libre du déflecteur de la surface à essuyer, afin d'obtenir une discontinuité minimale qui s'oppose le moins possible à l'action aérodynamique du déflecteur. It is known to bring the free edge of the deflector as close as possible to the surface to be wiped, in order to obtain a minimum discontinuity which opposes the aerodynamic action of the deflector as little as possible.
Cependant, un tel bord libre proche de la surface à essuyer est dangereux pour cette surface car il risque de frotter sur elle et l'endommager. However, such a free edge close to the surface to be wiped is dangerous for this surface because it risks rubbing on it and damaging it.
Pour pallier cet inconvénient, DE-A-3637348 a proposé que ce bord libre, d'une seule pièce avec le dêflecteur, soit en matériau plus mou que le reste du déflecteur. To overcome this drawback, DE-A-3637348 proposed that this free edge, in one piece with the deflector, be made of softer material than the rest of the deflector.
Une telle construction est très difficile à réaliser en pratique et principalement la réalisation de ce bord mou qu'il faut relier au reste du déflecteur. Such a construction is very difficult to achieve in practice and mainly the production of this soft edge which must be connected to the rest of the deflector.
La présente invention vise à fournir un déflecteur pour essuie-glace comportant un bord libre en matériau mou qui soit de construction simple et économique. The present invention aims to provide a deflector for a wiper comprising a free edge made of soft material which is simple and economical in construction.
A cet effet, le déflecteur pour essuie-glace selon l'invention est caractérisé par le fait que le déflecteur porte une pièce amovible munie d'une lèvre élastiquement déformable saillante au-delà du bord libre du déflecteur. To this end, the deflector for windshield wipers according to the invention is characterized in that the deflector carries a removable part provided with an elastically deformable lip projecting beyond the free edge of the deflector.
La pièce amovible peut être portée par le déflecteur par des moyens d'accrochage. The removable part can be carried by the deflector by hooking means.
De préférence les moyens d'accrochage consistent en une coopération par clipage d'au moins un alésage de la pièce amovible et au moins un téton saillant à partir du déflecteur. Preferably the attachment means consist of cooperation by clipping at least one bore of the removable part and at least one stud projecting from the deflector.
De plus la pièce amovible ainsi clipée sur le déflecteur est ainsi facilement démontable et peut être fabriquée par un procédé différent de celui du déflecteur, qui est en général en matière synthétique injectée. In addition, the removable part thus clipped to the deflector is thus easily removable and can be manufactured by a process different from that of the deflector, which is generally made of injected synthetic material.
L'ensemble ainsi réalisé permet un positionnement de la lèvre élastique au-dessous du déflecteur, avec une déformabilité librement choisie. The assembly thus produced allows positioning of the elastic lip below the deflector, with freely chosen deformability.
Selon une forme de réalisation de l'invention, la pièce amovible comporte un conduit d'arrosage et des buses d'arrosage. According to one embodiment of the invention, the removable part comprises a sprinkler pipe and sprinkler nozzles.
Selon une variante de l'invention, la pièce amovible est constituée d'un corps rigide portant la lèvre. According to a variant of the invention, the removable part consists of a rigid body carrying the lip.
De plus la lèvre est surmoulée sur le corps rigide. In addition, the lip is molded onto the rigid body.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
- la figure 1 est une vue schématique en coupe transversale de l'extrémité inférieure du déflecteur pour essuie-glace selon un exemple de réalisation de l'invention, et
- la figure 2 est analogue à la figure 1, pour une variante.The invention will be clearly understood on reading the following description made with reference to the appended drawing in which
FIG. 1 is a diagrammatic view in cross section of the lower end of the deflector for a wiper according to an exemplary embodiment of the invention, and
- Figure 2 is similar to Figure 1, for a variant.
En se référant aux figures 1 et 2, le déflecteur 1, apte à être solidarisé de manière connue en soi, a un balai d'essuie-glace ou à tout autre composant de l'essuie-glace, comporte une face frontale 2, une face arrière 3 et un bord libre 4 se situant généralement le plus près d'une vitre à essuyer. Referring to Figures 1 and 2, the deflector 1, capable of being secured in a manner known per se, has a wiper blade or any other component of the wiper, has a front face 2, a rear face 3 and a free edge 4 generally located closest to a window to be wiped.
Ce déflecteur 1 selon l'invention porte, ici sur sa face arrière 3, une pièce amovible 5 munie d'une lèvre 6 élastiquement déformable située en saillie au-dessous du bord libre 4, ladite lèvre évitant l'endommagement de la vitre à essuyer. This deflector 1 according to the invention carries, here on its rear face 3, a removable part 5 provided with an elastically deformable lip 6 projecting below the free edge 4, said lip preventing damage to the window to be wiped .
La pièce amovible 5 présente un corps rigide 7 lié au déflecteur I par des moyens d'accrochage 8 et portant sur sa partie la plus proche de la vitre la lèvre surmoulée 6. The removable part 5 has a rigid body 7 linked to the deflector I by attachment means 8 and bearing on its part closest to the glass the molded lip 6.
Les moyens d'accrochage 8 consistent en une coopération par clipage entre au moins un alésage 9 prévu sur le corps 7 et au moins un téton 10 issu de la face arrière 3 du déflecteur 1 et pouvant venir de moulage avec celui-ci. The attachment means 8 consist of cooperation by clipping between at least one bore 9 provided on the body 7 and at least one stud 10 coming from the rear face 3 of the deflector 1 and which can come from molding with the latter.
Ainsi la pièce amovible 5 peut être facilement déverrouillée par déclipage de la face arrière 3 pour permettre éventuellement son remplacement. Thus the removable part 5 can be easily unlocked by unclipping the rear face 3 to possibly allow its replacement.
Bien entendu il peut être envisagé, de par les moyens d'accrochage 8, que la pièce amovible 5 puisse être montée ou non selon les besoins
De plus la pièce amovible 5 présente un conduit d'arrosage 11 alimenté en liquide sous pression et, orthogonalement à la direction générale dudit conduit, des buses d'arrosage 12 dirigées-vers la vitre à essuyer.Of course it can be envisaged, by the attachment means 8, that the removable part 5 can be mounted or not as required
In addition, the removable part 5 has a sprinkler pipe 11 supplied with pressurized liquid and, orthogonally to the general direction of said pipe, sprinkler nozzles 12 directed towards the window to be wiped.
En se référant plus particulièrement à la figure 1, le conduit 11 et les buses 12 sont formés directement dans le corps rigide 7 de la pièce amovible 5, par exemple par usinage, alors que comme montre à la figure 2, le conduit 11 est formé par une première partie lIA venue de moulage avec le corps 7 et par une deuxième partie llB portée par un prolongement 3 formée conjointement avec la lèvre 6, lors du surmoulage de celle-ci, ledit prolongement portant en outre les buses d'arrosage 12. Referring more particularly to FIG. 1, the conduit 11 and the nozzles 12 are formed directly in the rigid body 7 of the removable part 5, for example by machining, while as shown in FIG. 2, the conduit 11 is formed by a first part IIa coming from molding with the body 7 and by a second part IIB carried by an extension 3 formed jointly with the lip 6, during the overmolding of the latter, said extension further carrying the spray nozzles 12.
