Description

La présente invention se rapporte au domaine de l'équipement automobile. Elle a plus particulièrement trait à un dispositif d'éclairage ou de signalisation pour véhicule automobile.The present invention relates to the field of automotive equipment. It relates more particularly to a lighting or signaling device for a motor vehicle.

Lors de la fabrication de tels dispositifs qui comprennent un boîtier pouvant constituer un miroir recevant une lampe et une glace, on scelle de manière étanche les bords du boîtier et de la glace par exemple par collage ou soudage. Cette liaison est destinée à isoler l'intérieur du boîtier de l'extérieur, de façon à rendre impossible l'entrée de tout agent extérieur, tel que de l'humidité. Bien entendu, la qualité de l'étanchéité doit pouvoir être contrôlée.During the manufacture of such devices which include a housing which can constitute a mirror receiving a lamp and an ice, the edges of the housing and of the ice are sealed, for example by gluing or welding. This connection is intended to isolate the interior of the housing from the outside, so as to make it impossible for any external agent, such as moisture, to enter. Of course, the quality of the seal must be able to be checked.

D'autre part, il est souvent prévu sur ces dispositifs un équipement qui permet au boîtier de "respirer" et d'éviter les phénomènes de condensation à l'intérieur de celui-ci. Cet équipement doit être conçu de façon à permettre l'aération du boîtier tout en empêchant toute entrée d'eau (par exemple lors du lavage du véhicule).On the other hand, equipment is often provided on these devices which allows the box to "breathe" and avoid condensation phenomena inside it. This equipment must be designed to allow ventilation of the box while preventing any entry of water (for example when washing the vehicle).

On a représenté sur les figures 1 et 2 annexées un équipement connu de ce genre, en forme de tube. La figure 1 est une vue en coupe transversale du tube et du bouchon qui l'équipe. La figure 2 est une vue en coupe axiale de ce même tube, selon le plan de coupe II de la figure 1. Sur cette figure apparaît le plan de coupe I-I du tube selon la figure 1.There is shown in Figures 1 and 2 attached a known equipment of this kind, in the form of a tube. Figure 1 is a cross-sectional view of the tube and the stopper which equips it. FIG. 2 is a view in axial section of this same tube, according to the section plane II of FIG. 1. In this figure appears the section plane I-I of the tube according to FIG. 1.

Ce tube horizontal 1, de forme générale cylindrique, est solidaire du boîtier (non représenté) par sa paroi de fond 11. Son extrémité libre est débouchante. Il comporte une cloison interne 12 qui s'étend horizontalement, sensiblement dans le plan médian du tube. On remarquera que la longueur de la cloison est inférieure à celle du tube proprement dit. Un trou 13 est ménagé dans la paroi 11 et fait communiquer l'intérieur du boîtier, situé à la gauche de la figure 2, avec l'intérieur du tube. Ce trou se situe au-dessus de la cloison, comme le montre la figure. De l'autre côté de la cloison, la paroi du tube comporte une ouverture 14 en forme de fente qui fait communiquer l'intérieur du tube avec le milieu extérieur. La fente 14 s'étend longitudinalement sur une partie seulement de la longueur du tube, en bas de celui-ci et débouche à l'extrémité libre de ce dernier.This horizontal tube 1, of generally cylindrical shape, is secured to the housing (not shown) by its bottom wall 11. Its free end opens out. It has an internal partition 12 which extends horizontally, substantially in the median plane of the tube. It will be noted that the length of the partition is less than that of the tube itself. A hole 13 is made in the wall 11 and communicates the interior of the housing, located to the left of FIG. 2, with the interior of the tube. This hole is located above the partition, as shown in the figure. On the other side of the partition, the wall of the tube has an opening 14 in the form of a slit which communicates the interior of the tube with the external medium. Slot 14 extends longitudinally over only part of the length of the tube, at the bottom thereof and opens out at the free end of the latter.

Le tube est fermé par un bouchon 2 qui comprend un élément tubulaire 21 fermé à une extrémité par un fond de forme discoïde 20. Le diamètre intérieur de l'élément tubulaire correspond (au jeu d'emboîtement près) au diamètre extérieur du tube 1, de façon à pouvoir s'y emmancher de manière étanche. Sa longueur est telle qu'il ne recouvre pas complètement la fente 14, comme le montre la figure 2.The tube is closed by a plug 2 which comprises a tubular element 21 closed at one end by a disc-shaped bottom 20. The inside diameter of the tubular element corresponds (to the nearest interlocking play) to the outside diameter of the tube 1, so that it can be fitted tightly. Its length is such that it does not completely cover the slot 14, as shown in FIG. 2.

Du fait que la cloison 12 est plus courte que le tube 1, il existe un passage A entre sa face d'extrémité 120 et le fond 20 du bouchon. Par exemple, la cloison 12 s'étend jusqu'à mi-distance entre le fond 20 et l'extrémité libre 210 de l'élément tubulaire 21.Because the partition 12 is shorter than the tube 1, there is a passage A between its end face 120 and the bottom 20 of the plug. For example, the partition 12 extends up to mid-distance between the bottom 20 and the free end 210 of the tubular element 21.

Ainsi, l'air peut librement circuler de l'intérieur du boîtier vers l'extérieur et réciproquement, via le trou 13, le passage A et la fente 14 sans que, pour autant, de l'eau provenant de l'extérieur puisse s'infiltrer dans le boîtier. En fait, la paroi 12 fait office de barrière. On constitue de cette façon une sorte de siphon.Thus, the air can freely circulate from the inside of the housing towards the outside and vice versa, via the hole 13, the passage A and the slot 14 without, however, water coming from the outside being able to s '' infiltrate the housing. In fact, the wall 12 acts as a barrier. This is a kind of siphon.

Préalablement au montage du bouchon, il peut être souhaitable de contrôler l'étanchéité du boîtier à l'aide d'un dispositif adéquat.Before mounting the cap, it may be desirable to check the tightness of the housing using an appropriate device.

Pour ce faire, on relie de façon étanche le boîtier à un dispositif en appliquant de l'air en surpression ou en dépression à celui-ci, via le tube 1. L'outillage du dispositif vient s'appliquer contre l'extrémité libre du conduit formé par la cloison 12 et la partie supérieure de la paroi 10 du tube. Compte-tenu de la forme connue de ces parties, il est nécessaire de prévoir un outillage complexe, adapté aux dimensions du tube et de la cloison. Cet outillage se révèle délicat à mettre en oeuvre, et inefficace notamment dès lors que les tolérances de fabrication sont importantes sur la distance qui sépare l'extrémité libre du tube de celle de la cloison.To do this, the housing is tightly connected to a device by applying overpressure or underpressure air thereto, via the tube 1. The tooling of the device is applied against the free end of the conduit formed by the partition 12 and the upper part of the wall 10 of the tube. Given the known shape of these parts, it is necessary to provide a complex tool, adapted to the dimensions of the tube and the partition. This tool proves to be difficult to use, and ineffective in particular when the manufacturing tolerances are large over the distance which separates the free end of the tube from that of the partition.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Pour ce faire, elle propose un dispositif qui, tout en permettant l'aération du boîtier comme le fait le dispositif décrit plus haut, autorise un contrôle d'étanchéité avec du matériel de type simple, fiable, facile à mettre en oeuvre, ceci, quelles que soient les tolérances de fabrication du tube. Ce dispositif présente les caractéristiques exposées dans la revendication 1.To do this, it offers a device which, while allowing the aeration of the housing as does the device described above, allows a tightness control with simple, reliable type of material, easy to implement, this, whatever the manufacturing tolerances of the tube. This device has the characteristics set out in claim 1.

Par ailleurs, d'autres caractéristiques avantageuses mais non limitatives sont exposées dans les sous-revendications.Furthermore, other advantageous but non-limiting characteristics are set out in the subclaims.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée d'un mode de réalisation préférentiel, faite en référence aux dessins annexés dans lesquels :

  • la figure 3 est une vue de côté, selon un plan de coupe vertical, d'un dispositif d'éclairage conforme à l'invention ;
  • la figure 4 est une vue en coupe transversale du tube qui équipe le dispositif, selon le plan de coupe IV-IV de la figure 5 ;
  • la figure 5 est une vue en coupe axiale de ce même tube, selon le plan de coupe V-V de la figure 4.
Other characteristics and advantages of the invention will appear on reading the detailed description of a preferred embodiment, made with reference to the appended drawings in which:
  • Figure 3 is a side view, along a vertical sectional plane, of a lighting device according to the invention;
  • Figure 4 is a cross-sectional view of the tube which equips the device, according to the section plane IV-IV of Figure 5;
  • FIG. 5 is a view in axial section of this same tube, according to the cutting plane VV of FIG. 4.

Dans l'ensemble de la présente description et des revendications, on entend par "glace" un couvercle ou autre élément de paroi en matériau transparent ou translucide destiné à être rendu solidaire du boîtier d'un dispositif d'éclairage ou de signalisation pour véhicule, et au travers duquel sont diffusés les rayons lumineux.Throughout the present description and of the claims, the term "glass" means a cover or other wall element of transparent or translucent material intended to be made integral with the housing of a lighting or signaling device for a vehicle, and through which the light rays are diffused.

La représentation du dispositif d'éclairage de la figure 3 est tout à fait schématique. Ce dispositif 3 comporte un boîtier 5 formant miroir de concentration. Au fond de ce boîtier est monté une lampe 7. Il reçoit de manière étanche une glace 4 de forme complémentaire, par exemple en matière plastique translucide. Le boîtier et la glace sont scellés l'un à l'autre de manière étanche, par exemple par collage.The representation of the lighting device of Figure 3 is quite schematic. This device 3 comprises a housing 5 forming a concentration mirror. At the bottom of this housing is mounted a lamp 7. It receives in a sealed manner a glass 4 of complementary shape, for example in translucent plastic. The housing and the glass are sealed together, for example by gluing.

Les moyens de montage de la lampe sur le boîtier et les moyens d'alimentation électrique de la lampe, bien connus, n'ont pas été représentés afin de ne pas alourdir inutilement la présente description ni les dessins.The means for mounting the lamp on the housing and the means for supplying power to the lamp, which are well known, have not been shown so as not to unnecessarily burden the present description or the drawings.

Sur la face externe du boîtier, et sensiblement dans sa partie supérieure, est disposé un tube 6 d'axe général horizontal, du même type général que le tube 1 décrit plus haut. Celui-ci peut former partie intégrante du boîtier.On the outer face of the housing, and substantially in its upper part, is disposed a tube 6 of generally horizontal axis, of the same general type as the tube 1 described above. This can form an integral part of the housing.

A la figure 5, la référence 61 correspond à la paroi du boîtier 5, qui sépare l'intérieur de celui-ci de l'intérieur du tube 6. Cette paroi a été représentée verticale (bien qu'elle soit réellement dirigée obliquement, comme le montre la figure 3), afin d'en simplifier la représentation.In FIG. 5, the reference 61 corresponds to the wall of the housing 5, which separates the interior thereof from the interior of the tube 6. This wall has been shown vertical (although it is actually directed obliquely, as shown in Figure 3), to simplify the representation.

Le tube 6 a une forme générale cylindrique et comporte dans son plan médian horizontal une cloison 62.The tube 6 has a generally cylindrical shape and has in its horizontal median plane a partition 62.

Ainsi que le montre la figure 5, les faces d'extrémité libre 600 et 620 du tube 6 et, respectivement, de la cloison 62 sont contenues dans un même plan P qui est transversal à la direction axiale XY du tube. On comprendra plus loin dans la description l'intérêt d'une telle caractéristique.As shown in FIG. 5, the free end faces 600 and 620 of the tube 6 and, respectively, of the partition 62 are contained in the same plane P which is transverse to the axial direction XY of the tube. It will be understood later in the description the advantage of such a characteristic.

Comme dans le tube connu, un trou traversant 63 est ménagé dans la paroi 61 du boîtier 5, et la paroi 60 du tube comporte dans sa partie basse une fente 64 débouchant à son extrémité libre.As in the known tube, a through hole 63 is formed in the wall 61 of the housing 5, and the wall 60 of the tube has in its lower part a slot 64 opening at its free end.

Dans le mode de réalisation décrit, le tube comporte trois surépaisseurs longitudinales qui forment des nervures axiales 65 disposées à sa périphérie, et distantes angulairement les unes des autres de 120°. Ainsi que cela se voit nettement à la figure 5 les nervures prennent naissance au niveau de la paroi 61 du socle et s'interrompent à une certaine distance de l'extrémité libre du 6 pour former un épaulement 650.In the embodiment described, the tube has three longitudinal thicknesses which form axial ribs 65 arranged at its periphery, and angularly spaced from one another by 120 °. As can be clearly seen in FIG. 5, the ribs originate at the level of the wall 61 of the base and are interrupted at a certain distance from the free end of the 6 to form a shoulder 650.

Cette distance est plus grande que la longueur de paroi non fendue située dans le prolongement de la fente 64, à la base du tube.This distance is greater than the length of the unsplit wall located in the extension of the slot 64 at the base of the tube.

On notera que la cloison interne 62 subdivise l'intérieur du tube en deux espaces adjacents et superposés El et E2. L'espace supérieur El communique avec l'intérieur du boîtier par le trou 63, tandis que l'espace inférieur E2 communique avec l'extérieur par la fente 64.It will be noted that the internal partition 62 subdivides the interior of the tube into two adjacent and superimposed spaces El and E2. The upper space E1 communicates with the interior of the housing through the hole 63, while the lower space E2 communicates with the exterior through the slot 64.

Le tube est fermé à son extrémité libre par un bouchon tubulaire 8 du même type que le bouchon 2 décrit plus haut. Il comprend une partie tubulaire 81 dont le diamètre interne correspond au diamètre externe du tube 6 de manière à pouvoir s'y emmancher de manière étanche. La partie tubulaire 81 est fermée à l'une de ses extrémités par un fond de forme discoïde 80.The tube is closed at its free end by a tubular plug 8 of the same type as the plug 2 described above. It comprises a tubular part 81 whose internal diameter corresponds to the external diameter of the tube 6 so as to be able to fit therein in a sealed manner. The tubular part 81 is closed at one of its ends by a disc-shaped bottom 80.

Comme le montre la figure 5, les épaulements 650 des nervures 65 forment une butée qui limite l'enfoncement du bouchon 8. De cette façon, l'air peut librement circuler entre l'espace E1 et l'espace E2 via le passage A formé entre l'extrémité libre de la cloison 62 et le fond 80 du bouchon. Il assure donc une parfaite aération du boîtier 3 sans autoriser les rentrées d'eau à l'intérieur de celui-ci.As shown in FIG. 5, the shoulders 650 of the ribs 65 form a stop which limits the insertion of the plug 8. In this way, the air can freely circulate between the space E1 and the space E2 via the passage A formed between the free end of the partition 62 and the bottom 80 of the plug. It therefore ensures perfect ventilation of the housing 3 without allowing the inflow of water inside it.

Le dispositif de l'invention permet un contrôle de l'étanchéité du boîtier de manière simple après enlèvement du bouchon 8. En effet, du fait que les faces d'extrémité libre 600 et 620 de la cloison et du tube se trouvent dans un même plan, la connexion, de manière étanche, du tube au dispositif permettant de contrôler l'étanchéité se fait très facilement et efficacement, par exemple par appui d'un joint plat contre ces faces d'extrémité. Il n'est donc plus nécessaire d'utiliser un outillage sophistiqué dont le bon fonctionnement est tributaire notamment des tolérances de fabrication et de l'alignement.The device of the invention makes it possible to check the tightness of the housing in a simple manner after removing the plug 8. In fact, because the free end faces 600 and 620 of the partition and the tube are in the same plan, the connection, in leaktight manner, of the tube to the device making it possible to check the seal is very easily and effectively, for example by pressing a flat seal against these end faces. It is therefore no longer necessary to use sophisticated tools, the proper functioning of which depends in particular on manufacturing tolerances and alignment.

Selon une variante de réalisation, les nervures 65 sont remplacées par une surépaisseur externe qui s'étend sur toute la périphérie du tube, mais seulement sur une certaine longueur de celui-ci.According to an alternative embodiment, the ribs 65 are replaced by an external allowance which extends over the entire periphery of the tube, but only over a certain length of the latter.

Selon d'autres modes de réalisation, les moyens formant butée consistent soit en des nervures, soit en une surépaisseur prévues à l'intérieur du bouchon 8. Selon le cas, les nervures ou la surépaisseur viennent en butée contre la face d'extrémité 600 du tube.According to other embodiments, the means forming a stop consist either of ribs or of an additional thickness provided inside the plug 8. Depending on the case, the ribs or the additional thickness abut against the end face 600 of the tube.
