Description

DISPOSITIF ESCAMOTABLE DE LAVAGE D'UNE GLACE DE
VEHICULE AUTOMOBILE
L'invention concerne un dispositif escamotable de lavage d'une glace de véhicule automobile.RETRACTABLE DEVICE FOR WASHING A GLASS
MOTOR VEHICLE
The invention relates to a retractable device for washing a motor vehicle window.

De tels dispositifs sont avantageusement utilisés notamment pour laver une glace de pare-brise ou celle d'un projecteur de véhicule.Such devices are advantageously used in particular for washing a windshield glass or that of a vehicle headlight.

Un exemple de dispositif connu par la publication FR-A-2151905 est constitué par un ou plusieurs gicleurs disposés sur un pare-choc ou sur un élément de la carrosserie tel qu'une tôle d'auvent localisée à la base du pare-brise.An example of a device known from the publication FR-A-2151905 consists of one or more nozzles arranged on a bumper or on an element of the bodywork such as a canopy sheet located at the base of the windshield.

Les gicleurs sont alors reliés par des canalisations à une pompe d'alimentation qui aspire le liquide de lavage d'un réservoir et le refoule dans les canalisations.The nozzles are then connected by pipes to a supply pump which draws the washing liquid from a tank and discharges it into the pipes.

La publication FR-A-2605906 décrit un gicleur escamotable porté par une tige de piston coulissante soumise à un mouvement de rotation sur une partie de la course de la tige.The publication FR-A-2605906 describes a retractable nozzle carried by a sliding piston rod subjected to a rotational movement over part of the stroke of the rod.

Lorsque les gicleurs ne sont pas alimentés par le liquide sous pression ceux-ci sont soumis à des agents polluants dont l'agressivité nuit à l'éjection efficace du liquide de lavage.When the nozzles are not supplied by the pressurized liquid, they are subjected to polluting agents whose aggressiveness harms the effective ejection of the washing liquid.

L'invention a pour objet de remédier à cet inconvénient et concerne un dispositif escamotable dans lequel le gicleur est porté par un support monté mobile par rapport à une base de fixation entre une position escamotée au contact de la base et une position de service déployée.The invention aims to remedy this drawback and relates to a retractable device in which the nozzle is carried by a support mounted movable relative to a fixing base between a retracted position in contact with the base and a deployed service position.

Le dispositif est caractérisé par le fait que des moyens élastiques de rappel du support au contact de la base en position escamotée,exercent un effort antagoniste à un effort de commande de déplacement dudit support mobile du gicleur sous l'action de la pression du fluide dans le conduit. The device is characterized by the fact that elastic means for returning the support in contact with the base in the retracted position exert a force opposing a force for controlling the movement of said mobile support of the nozzle under the action of the pressure of the fluid in leads him.

D'autres caractéristiques et avantages du dispositif apparaîtront à la lecture d'un exemple de réalisation de celuici en référence au dessin annexé dans lequel: - la figure 1 est une représentation schématique des localisations
possibles du dispositif sur une carrosserie d'un véhicule automobile, - la figure 2 est une représentation schématique perspective du
dispositif, - la figure 3 est une vue en coupe axiale schématique du dispositif de
lavage monté à proximité d'une glace de bloc optique, - la figure 4 est une vue similaire à celle de la figure 3 montrant le
dispositif de lavage en position escamotée.Other characteristics and advantages of the device will appear on reading an exemplary embodiment of this with reference to the appended drawing in which: - Figure 1 is a schematic representation of the locations
possible of the device on a bodywork of a motor vehicle, - Figure 2 is a schematic perspective representation of
device, - Figure 3 is a schematic axial sectional view of the device
washing mounted near an optical unit glass, - Figure 4 is a view similar to that of Figure 3 showing the
washing device in retracted position.

Sur la figure 1 on a représenté une carrosserie 1 d'un véhicule automobile portant un pare-brise 2 et un élément pare-choc 3.FIG. 1 shows a bodywork 1 of a motor vehicle carrying a windshield 2 and a bumper element 3.

Le dispositif de lavage 10 destiné au nettoyage du pare-brise 2 ou d'une glace de plan 5, est montré en position extraite d'utilisation,disposé dans un logement de l'auvent 4 ou de l'élément pare-choc 3.The washing device 10 intended for cleaning the windshield 2 or a plane glass 5, is shown in the extracted position of use, placed in a housing of the awning 4 or of the bumper element 3.

Le dispositif de lavage 10 représenté à la figure 2 possède une base de fixation 11 dont les parois extrêmes opposées portent des moyens d'accrochage et de retenue 12 au contact des parois 13 de l'auvent 4.perçé d'une ouverture de montage 14 du dispositif comme représenté à la figure 3.The washing device 10 shown in FIG. 2 has a fixing base 11 whose opposite end walls carry hooking and retaining means 12 in contact with the walls 13 of the awning 4. pierced with a mounting opening 14 of the device as shown in Figure 3.

La base de fixation 11 porte un axe d'articulation 15 d'un support mobile 16 qui porte au moins un gicleur 17 connu en soisqui peut être constitué à titre d'exemple par une bille munie d'un perçage d'évacuation du liquide de lavage et sertie dans la paroi d'une chambre d'arrivée de liquide 19.The fixing base 11 carries a hinge pin 15 of a movable support 16 which carries at least one nozzle 17 known in soisqui can be constituted by way of example by a ball provided with a hole for discharging the liquid of washing and set in the wall of a liquid inlet chamber 19.

Dans la chambre 19 débouche également l'orifice d'un raccord 20 sur lequel est branché un conduit d'alimentation 21 du dispositif. Le conduit 21 est collé sur la paroi d'une rainure longitudinale 22s, 22b qui s'étend au contact de la face supérieure de la base 11 et du support 16. In the chamber 19 also opens the orifice of a connector 20 to which a supply conduit 21 of the device is connected. The duct 21 is glued to the wall of a longitudinal groove 22s, 22b which extends in contact with the upper face of the base 11 and the support 16.

Au voisinage de l'axe d'articulation 15, les rainures 22s et 22b sont interrompues et le conduit 21 présente une zone 211 d'étranglement non collée destiné à interrompre le débit de fluide.In the vicinity of the articulation axis 15, the grooves 22s and 22b are interrupted and the conduit 21 has an unbonded throttling zone 211 intended to interrupt the flow of fluid.

Un ressort 23 monté en flexion entre le support 16 et la base 1 1 est constitué par une spire d'enroulement dont les extrémités de retenue sont respectivement en appui sur lesdits supports 16 et base 11. Le ressort 23 exerce de la sorte un effort de rappel du support 16 au contact de la base 11, antagoniste à l'effort de commande de déplacement angulaire du support mobile 16 sous l'action de la pression du fluide dans le conduit 21.A spring 23 mounted in bending between the support 16 and the base 1 1 is constituted by a winding turn whose retaining ends are respectively supported on said supports 16 and base 11. The spring 23 thus exerts a force of return of the support 16 in contact with the base 11, antagonistic to the angular displacement control effort of the mobile support 16 under the action of the pressure of the fluid in the conduit 21.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

Une pompe 30 aspire le liquide de lavage d'un réservoir de fluide 31 et refoule celui-ci dans une canalisation principale dont une dérivation est branchée sur le conduit d'alimentation 21. En position de repos de la pompe aucune pression n'est établie dans le conduit 21. Le tarage du ressort 23 maintient le support 16 au contact de la base 11 comme indiqué à la figure 4.A pump 30 sucks the washing liquid from a fluid reservoir 31 and discharges it into a main pipe, a branch of which is connected to the supply duct 21. In the pump's rest position, no pressure is established in the duct 21. The calibration of the spring 23 keeps the support 16 in contact with the base 11 as shown in FIG. 4.

Lorsque la pompe 30 établit une pression dans la canalisation principale, le conduit 21 est sous pression et la pression du fluide s'établit dans le tronçon du conduit au contact de la rainure 22b. La pression du fluide appliquée dans la zone 211 du conduit 21 exerce une force F légèrement supérieure à la force de tarage du ressort 23 suffisant pour ériger le support 16 comme cela a été représenté à la figure 3.When the pump 30 establishes a pressure in the main pipe, the conduit 21 is under pressure and the pressure of the fluid is established in the section of the conduit in contact with the groove 22b. The pressure of the fluid applied in the zone 211 of the conduit 21 exerts a force F slightly greater than the setting force of the spring 23 sufficient to erect the support 16 as shown in FIG. 3.

Sans sortir du cadre de l'invention le support 16 pourra porter plusieurs gicleurs tels que 17 dont l'orientation sera adaptée à la position relative de la glace à laver. Without departing from the scope of the invention, the support 16 may carry several nozzles such as 17, the orientation of which will be adapted to the relative position of the ice to be washed.
