Abstract

The indicator has a spherical float (3) connected to an upper end of a neck (2) of a liquid tank (1) by a flexible cable (4). The flexible cable is fixed at a base of a stopper (6) used for closing the neck, where length of the flexible cable is chosen such that the float does not move lower than a lower end (8) of the neck when the level of liquid i.e. windscreen washer fluid (7), in the tank is low. The float has an acidulous color, where the float starts to float on the surface of the washer fluid as the washer fluid level raises toward a filling opening of the neck.

Description

INDICATEUR DE NIVEAU POUR RESERVOIR DE LIQUIDE D'UN VEHICULE AUTOMOBILE La présente invention concerne un indicateur de niveau pour réservoir de liquide d'un véhicule automobile, le réservoir comprenant un goulot de remplissage. The present invention relates to a level indicator for a liquid reservoir of a motor vehicle, the reservoir comprising a filler neck.

10 Un tel indicateur de niveau est connu par exemple de la demande de brevet français FR 2 914 255 Al. Such a level indicator is known for example from the French patent application FR 2 914 255 A1.

Lors du remplissage du réservoir de liquide lave-vitre, souvent, on se laisse surprendre par la limite haute du remplissage. Si le liquide 15 utilisé n'est pas de couleur, ou si le remplissage se fait dans un endroit sombre, comme dans un garage ou au fond d'un box, on ne voit pas le niveau de liquide atteindre la limite de remplissage. When filling the windshield washer fluid tank, we often get surprised by the upper limit of the filling. If the liquid used is not colored, or if the filling is done in a dark place, such as in a garage or at the bottom of a box, we do not see the liquid level reach the filling limit.

Actuellement, on peut deviner le niveau de remplissage grâce à la 20 matière transparente des goulots. Currently, one can guess the filling level thanks to the transparent material of the necks.

Actuellement, les constructeurs automobiles utilisent de plus en plus des réservoirs en matière recyclée y compris les goulots. Cette matière recyclée n'est plus transparente, souvent noire, en raison du 25 faible coût d'une telle matière. Si les goulots de remplissage ne sont plus transparents, ils empêchent de voir le niveau de remplissage. Currently, car manufacturers are increasingly using recycled tanks including bottlenecks. This recycled material is no longer transparent, often black, because of the low cost of such a material. If the filler necks are no longer transparent, they prevent you from seeing the filling level.

La présente invention a pour but de remédier à ces inconvénients et de proposer un indicateur de niveau pour réservoir de liquide d'un 30 véhicule automobile, qui permette à l'utilisateur de ne pas trop remplir son réservoir de liquide et ainsi d'éviter de renverser du liquide en se faisant surprendre par la montée du niveau. En outre, la présente5 The object of the present invention is to overcome these drawbacks and to propose a level indicator for a liquid reservoir of a motor vehicle, which enables the user not to overfill his liquid reservoir and thus to avoid to spill liquid by being surprised by the rise of the level. In addition, the present5

invention doit permettre l'utilisation des matières recyclées pour le réservoir de liquide avec son goulot. The invention must allow the use of recycled materials for the liquid reservoir with its neck.

Pour accomplir ce but, la présente invention propose un indicateur de niveau pour réservoir de liquide d'un véhicule automobile, le réservoir comprenant un goulot de remplissage, dans lequel un flotteur relié par un câble souple à l'extrémité haute du goulot. To accomplish this object, the present invention provides a level indicator for a liquid reservoir of a motor vehicle, the reservoir comprising a filler neck, wherein a float connected by a flexible cable to the upper end of the neck.

Avantageusement, le flotteur a une forme sphérique. De préférence, le câble souple est fixé au goulot à la base du bouchon de fermeture du goulot. Advantageously, the float has a spherical shape. Preferably, the flexible cable is attached to the neck at the base of the closure cap of the neck.

Selon un mode de réalisation alternatif, le câble souple est fixé sur 15 le couvercle du bouchon de fermeture du goulot. According to an alternative embodiment, the flexible cable is fixed on the lid of the closure cap of the neck.

Selon un mode de réalisation préféré, la longueur du câble souple est choisie de telle sorte qu'au niveau bas du liquide dans le réservoir, le flotteur ne puisse pas descendre plus bas que l'extrémité inférieure 20 du goulot. According to a preferred embodiment, the length of the flexible cable is chosen such that at the low level of the liquid in the tank, the float can not go lower than the lower end of the neck.

Avantageusement, le flotteur a une couleur acidulée. Advantageously, the float has a tart color.

L'invention est maintenant décrite en référence aux dessins 25 annexés, non limitatifs, dans lesquels: The invention is now described with reference to the appended, non-limiting drawings, in which:

Fig. 1 est une vue en coupe transversale d'un réservoir de liquide avec goulot, comprenant un mode de réalisation de l'indicateur de niveau selon l'invention, le réservoir étant rempli de liquide à 30 son niveau bas; et Fig.2 montre le réservoir de Fig. 1 rempli de liquide à son niveau haut. Fig. 1 is a cross-sectional view of a necked liquid reservoir, comprising an embodiment of the level indicator according to the invention, the reservoir being filled with liquid at its low level; and Fig.2 shows the reservoir of FIG. 1 filled with liquid at its high level.

Comme le montre Fig.l, le réservoir 1 qui comprend un goulot 2 comprend du liquide, par exemple du liquide lave-vitre 7 à son niveau bas. Le flotteur 3 a dans le mode de réalisation présenté la forme d'une sphère. Il est fixé à un câble souple 4 qui lui-même est fixé à l'extrémité supérieure 5 du goulot. As shown in Fig.l, the tank 1 which comprises a neck 2 comprises liquid, for example washing liquid window 7 at its low level. The float 3 has in the embodiment shown in the form of a sphere. It is attached to a flexible cable 4 which itself is attached to the upper end 5 of the neck.

Il est clair que le matériau du flotteur 3 doit avoir une densité spécifique inférieure à celle du liquide stocké dans le réservoir. 10 Le câble souple 4 présente une longueur telle que le flotteur 3 peut descendre au maximum jusqu'à l'extrémité inférieure 8 du goulot 2, quand le niveau du liquide 7 dans le réservoir 1 est à un niveau bas. On évite ainsi que le flotteur puisse rester bloqué dans la structure de la 15 partie haute du réservoir 1. Selon un mode de réalisation alternatif, le câble souple 4 est fixé sur le couvercle 6 du bouchon de fermeture du goulot 2. It is clear that the material of the float 3 must have a specific density lower than that of the liquid stored in the tank. The flexible cable 4 has a length such that the float 3 can descend as far as possible to the lower end 8 of the neck 2, when the level of the liquid 7 in the tank 1 is at a low level. This avoids that the float can remain blocked in the structure of the upper part of the tank 1. According to an alternative embodiment, the flexible cable 4 is fixed on the lid 6 of the closure cap of the neck 2.

En remplissant le réservoir y compris son goulot 2 de remplissage 20 avec du liquide à stocker, par exemple du liquide lave-vitre, quand le niveau du liquide arrive dans le goulot 2, le flotteur 3 commence à flotter à la surface du liquide et monte avec le liquide en direction de l'orifice de remplissage du goulot 2. By filling the reservoir including its filler neck 20 with liquid to be stored, for example windshield washer fluid, when the liquid level arrives in the neck 2, the float 3 begins to float on the surface of the liquid and rises with the liquid towards the filler opening of the neck 2.

25 Avantageusement, le flotteur peut avoir une couleur acidulée pour être mieux aperçu par l'utilisateur. Dès que le flotteur arrive au niveau du bord supérieur du goulot 2, il est dans le champ de vue de l'utilisateur qui peut arrêter immédiatement l'écoulement du liquide et empêcher ainsi un débordement du liquide.Advantageously, the float may have an acidic color to be better perceived by the user. As soon as the float arrives at the upper edge of the neck 2, it is in the field of view of the user who can immediately stop the flow of liquid and thus prevent overflow of the liquid.

30 Ainsi, il peut faire une économie du liquide, par exemple du liquide lave-vitre, et en même temps, il évite de salir le sol où est entreposé le véhicule. La présente invention n'est pas limitée aux modes de réalisation ci-dessus décrits. Ainsi, le flotteur peut présenter toute forme adaptée à son utilisation. Thus, it can save the liquid, for example windshield washer fluid, and at the same time, it avoids dirtying the soil where the vehicle is stored. The present invention is not limited to the embodiments described above. Thus, the float may have any form adapted to its use.
