Description
LAVE-PHARE ESCAMOTABLE
L'invention concerne un lave-phare escamotable qui possède au moins un gicleur fixé à un piston coulissant.WINDSHIELD WASHER
The invention relates to a retractable headlight washer which has at least one nozzle attached to a sliding piston.
L'invention concerne plus particulièrement un gicleur mobile par rapport à un pare-chocs de véhicule automobile qui possède une position de repos escamotée au contact de la face avant du pare-chocs et une position de travail extérieure audit pare-chocs.The invention relates more particularly to a nozzle movable relative to a motor vehicle bumper which has a retracted rest position in contact with the front face of the bumper and a working position external to said bumper.
La publication FR-A-2.675.445 décrit un lave-phare dans lequel un support de gicleur porte un obturateur dont la surface assure une jonction avec celle du pare-chocs dans la position escamotée du lave-phare.The publication FR-A-2.675.445 describes a headlight washer in which a nozzle support carries a shutter whose surface provides a junction with that of the bumper in the retracted position of the headlight washer.
Par suite des variations de la tolérance de montage du pare-chocs on constate fréquemment que la position escamotée du lave-phare n'assure plus la jonction entre la surface de l'obturateur et celle du pare-chocs.As a result of variations in the mounting tolerance of the bumper, it is frequently found that the retracted position of the headlight washer no longer ensures the junction between the surface of the shutter and that of the bumper.
L'esthétique et la qualité de finition du véhicule ne sont pas de ce fait constantes.The aesthetics and quality of finish of the vehicle are therefore not constant.
Il est de ce fait nécessaire d'effectuer des ajustements intermédiaires pour replacer le gicleur en position correcte et de modifier la position de repos du piston coulissant.It is therefore necessary to make intermediate adjustments to return the nozzle to the correct position and to modify the rest position of the sliding piston.
Lorsque la surface de l'obturateur est faiblement inclinée sur l'axe du piston il est particulièrement difficile d'obtenir un lavage efficace du phare en raison de l'imprécision et de la dispersion du jet du fluide de lavage.When the surface of the shutter is slightly inclined on the axis of the piston it is particularly difficult to obtain an effective washing of the headlight due to the imprecision and the dispersion of the jet of the washing fluid.
Le but de l'invention est donc de proposer un lave-phare escamotable à efficacité améliorée dont le gicleur se prolonge par un obturateur de l'orifice d'éjection dudit gicleur au travers de la paroi du pare-chocs, ce lave-phare présentant une structure simple d'ajustage de l'obturateur dans sa position escamotée de manière à préserver l'aspect esthétique et de bonne finition du véhicule.The object of the invention is therefore to propose a retractable headlight washer with improved efficiency, the nozzle of which is extended by a shutter of the ejection orifice of said nozzle through the wall of the bumper, this headlight washer having a simple structure for adjusting the shutter in its retracted position so as to preserve the aesthetic appearance and good finish of the vehicle.
Un autre but de l'invention est de proposer un gicleur monté sur un support mobile qui se prolonge en direction du pare-chocs par un pied de montage flexible porteur de l'obturateur. Un tel pied de montage favorise de ce fait l'auto-ajustage de l'obturateur au contact de la paroi du parechocs.Another object of the invention is to provide a nozzle mounted on a mobile support which is extended towards the bumper by a flexible mounting foot carrying the shutter. Such a mounting foot thereby promotes self-adjustment of the shutter in contact with the wall of the bumper.
Selon une caractéristique de l'invention, l'obturateur porte un déflecteur de jet orienté en direction du bord inférieur de la glace du phare.According to a characteristic of the invention, the shutter carries a jet deflector oriented in the direction of the lower edge of the headlight glass.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture d'un mode de réalisation du lave-phare en référence au dessin annexé dans lequel - la figure 1 est une représentation schématique de la face avant d'un
véhicule automobile équipé de deux lave-phares,
la figure 2 est une vue en coupe partielle de la face avant du véhicule
réalisée dans l'axe du lave-phare suivant la ligne II de la figure 1,
dans laquelle le lave-phare est dans une position escamotée.Other characteristics and advantages of the invention will appear on reading an embodiment of the headlight washer with reference to the appended drawing in which - Figure 1 is a schematic representation of the front face of a
motor vehicle fitted with two headlight washers,
Figure 2 is a partial sectional view of the front of the vehicle
carried out in the axis of the headlight washer along line II of FIG. 1,
in which the headlight washer is in a retracted position.
- la figure 3 est une vue en coupe partielle de la face avant du véhicule
réalisée dans l'axe du lave-phare, dans laquelle le lave-phare est dans
une position de travail.- Figure 3 is a partial sectional view of the front of the vehicle
carried out in the axis of the headlight washer, in which the headlight washer is in
a working position.
la figure 4 est une vue en perspective de l'obturateur suivant la
flèche A de la figure 3.Figure 4 is a perspective view of the shutter according to the
arrow A in figure 3.
Ainsi que cela est montré à la figure 1, l'avant du véhicule comporte une calandre 1 en partie masquée par le capot 2 du compartiment moteur du véhicule.As shown in Figure 1, the front of the vehicle has a grille 1 partially masked by the cover 2 of the vehicle engine compartment.
La calandre 1 porte par ailleurs des fenêtres latérales d'encastrement de deux phares 3 localisées au-dessus d'un pare-chocs 4.The grille 1 also carries side windows for embedding two headlights 3 located above a bumper 4.
Des lave-phares 5 sont localisés de part et d'autre de la partie médiane du pare-chocs 4 à proximité des glaces 31 des phares 3.Headlight washers 5 are located on either side of the middle part of the bumper 4 near the windows 31 of the headlights 3.
Ainsi que cela est montré aux figures 2 et 3, la paroi 10 du pare-chocs 4 possède un orifice 11 dans lequel s'encastre un obturateur mobile 12. A cet effet, l'obturateur 12 est porté par le support mobile 14 du gicleur 13 solidaire d'un piston coulissant 15. Le cylindre 16 du piston 15 est monté sur un élément de structure fixe 17 et est alimenté en fluide sous pression véhiculé par une pompe 18 à partir d'un réservoir 19. Lorsque le piston 15 est en bout de course, le cylindre 16 est en communication avec le gicleur
13 et permet l'arrosage de la glace 31 du phare 3.As shown in Figures 2 and 3, the wall 10 of the bumper 4 has an orifice 11 in which a movable shutter 12 is fitted. For this purpose, the shutter 12 is carried by the movable support 14 of the nozzle 13 secured to a sliding piston 15. The cylinder 16 of the piston 15 is mounted on a fixed structural element 17 and is supplied with pressurized fluid conveyed by a pump 18 from a reservoir 19. When the piston 15 is in limit switch, cylinder 16 is in communication with the nozzle
13 and allows watering of the ice 31 of the headlight 3.
L'obturateur 12 porte un déflecteur 20 de jet orienté en direction du bord inférieur 3i de la glace 3 du phare.The shutter 12 carries a jet deflector 20 oriented in the direction of the lower edge 3i of the lens 3 of the headlight.
Le déflecteur 20 porte également des ailes latérales destinées à canaliser le jet 21 du fluide de lavage . L'obturateur 12 est par ailleurs encastré sur un pied de montage 22 flexible sur lequel une base 23 est accolée à la face avant du support mobile 14 du gicleur 13. La base 23 porte une liaison flexible autoajustable constituée par des lames d'ancrage élastiques préformées 24 munies des terminaisons d'encastrement 25 de l'obturateur 12. The deflector 20 also carries lateral wings intended to channel the jet 21 of the washing fluid. The shutter 12 is also embedded on a flexible mounting foot 22 on which a base 23 is attached to the front face of the movable support 14 of the nozzle 13. The base 23 carries a flexible self-adjusting connection constituted by elastic anchoring blades preformed 24 provided with mounting endings 25 of the shutter 12.
Dans le but de faciliter le centrage de l'obturateur et la jonction des surfaces respectives de l'obturateur 12 et du pare-chocs 4, la calandre 1 possède également une ouverture d'encastrement du déflecteur 20.In order to facilitate centering of the shutter and the junction of the respective surfaces of the shutter 12 and the bumper 4, the grille 1 also has a recess opening for the deflector 20.
En outre une simplification de montage peut être obtenue par le fait que, l'obturateur 12 et le pied de montage 22 constituent un ensemble préassemblé avec le support 14 du gicleur 13. In addition, a simplification of assembly can be obtained by the fact that the shutter 12 and the mounting base 22 constitute a preassembled assembly with the support 14 of the nozzle 13.
