Description

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

Lors de la fabrication de tels dispositifs qui comprennent un boîtier abritant un miroir recevant une lampe et fermé par une glace, on scelle de manière étanche les bords du boîtier et de la glace, par exemple à l'aide d'un joint. 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 ou des salissures.During the manufacture of such devices which include a housing housing a mirror receiving a lamp and closed by a glass, the edges of the housing and the glass are sealed, for example using a seal. This connection is intended to isolate the interior of the housing from the outside, so as to make it impossible for any external agent to enter, such as humidity or dirt.

Cependant, une étanchéité parfaite s'avère dans la pratique impossible à réaliser, et par des phénomènes répétés de différences de pression entre l'intérieur et l'extérieur du boîtier, dûs notamment à l'échauffement du projecteur allumé, de l'humidité finit toujours par pénétrer dans le boîtier pour se condenser en particulier sur la glace.However, perfect sealing proves in practice impossible to achieve, and by repeated phenomena of pressure differences between the inside and the outside of the case, due in particular to the heating of the switched on projector, humidity ends always enter the case to condense, especially on ice.

D'autre part, il est souvent prévu sur ces dispositifs un équipement qui permet au boîtier de "respirer", c'est-à-dire 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) ou de boue.On the other hand, equipment is often provided on these devices which allows the case to "breathe", that is to say to avoid the phenomena of condensation 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) or mud.

La présente invention vise à proposer un nouvel équipement de ce genre qui permet à la fois de réaliser une aération efficace, sans entrée d'eau ou de boue, tout en étant simple et économique à réaliser.The present invention aims to propose a new equipment of this kind which allows both to achieve effective ventilation, without entry of water or mud, while being simple and economical to achieve.

Conformément à l'invention, ce dispositif d'éclairage ou de signalisation pour véhicule, comprenant un boîtier renfermant une lampe et auquel une glace est fixée de manière étanche, du type comprenant un conduit solidaire du boîtier, qui met en communication l'intérieur avec l'extérieur, est caractérisé par le fait que :

  • le conduit s'étend selon une direction générale descendante le long d'une paroi du boîtier, et est délimité par ladite paroi et un bouchon de forme complémentaire ;
  • le conduit communique avec l'intérieur du boîtier par un passage prévu dans sa région supérieure et avec l'extérieur par une ouverture de section plus petite que celle du conduit ;
  • il comporte un tube débouchant, en saillie vers le bas à l'intérieur du conduit, lequel présente une section plus petite que celle du conduit, ce tube se raccordant à au moins une paroi latérale du conduit ;
  • il est équipé d'un élément formant écran disposé à l'aplomb de l'ouverture inférieure du tube, à distance de celui-ci et à l'intérieur du conduit.
According to the invention, this lighting or signaling device for a vehicle, comprising a housing containing a lamp and to which a lens is tightly fixed, of the type comprising a duct secured to the housing, which puts the interior in communication with the exterior, is characterized by the fact that:
  • the conduit extends in a general downward direction along a wall of the housing, and is delimited by said wall and a plug of complementary shape;
  • the conduit communicates with the interior of the housing through a passage provided in its upper region and with the exterior through an opening of smaller section than that of the conduit;
  • it comprises a tube emerging, projecting downwards inside the conduit, which has a smaller section than that of the conduit, this tube connecting to at least one side wall of the conduit;
  • it is equipped with a screen element arranged directly above the lower opening of the tube, at a distance from the latter and inside the duct.

Selon d'autres caractéristiques avantageuses mais non limitatives :

  • le dispositif est en outre pourvu d'une saillie en forme de plaquette disposée entre le passage et l'ouverture inférieure du tube, cette saillie se raccordant à la paroi du conduit et s'étendant sur une partie de la profondeur de celui-ci ;
  • la saillie s'étend au niveau de l'ouverture supérieure du tube ;
  • le tube se raccorde à deux parois latérales opposées du conduit, les espaces situés entre le tube et les parois latérales formant des culs de sac ;
  • ledit élément formant écran a une section droite en forme de "V"
  • ledit élément formant écran a une section droite en forme d'arc de cercle ;
  • la face concave dudit élément est tournée vers l'ouverture inférieure dudit conduit ;
  • le conduit affecte, en vue de face, une forme oblongue ;
  • le conduit affecte, en vue de face, une forme généralement elliptique ;
  • le passage est défini à sa base par une partie de cloison inclinée de forme concave.
According to other advantageous but non-limiting characteristics:
  • the device is also provided with a projection in the form of a plate arranged between the passage and the lower opening of the tube, this projection connecting to the wall of the conduit and extending over part of the depth thereof;
  • the projection extends at the upper opening of the tube;
  • the tube is connected to two opposite side walls of the conduit, the spaces between the tube and the side walls forming dead ends;
  • said screen member has a "V" shaped cross section
  • said screen member has a cross section in the shape of an arc of a circle;
  • the concave face of said element is turned towards the lower opening of said duct;
  • the duct assumes, in front view, an oblong shape;
  • the duct assumes, in front view, a generally elliptical shape;
  • the passage is defined at its base by a part of an inclined partition of concave shape.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée de deux modes de réalisation préférentiels, faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de côté, selon un plan de coupe longitudinal, du conduit formant partie d'un premier mode de réalisation du dispositif conforme à l'invention ;
  • la figure 2 est une vue de face, selon le plan de coupe I-I, de ce même dispositif ;
  • la figure 3 est similaire à la figure 2 et est destinée à illustrer les voies de circulation de l'air et de l'eau à l'intérieur du conduit ;
  • les figures 4 à 6 sont des vues respectivement similaires aux figures 1 à 3 mais illustrant le conduit d'un second mode de réalisation du dispositif.
Other characteristics and advantages of the invention will appear on reading the detailed description of two embodiments preferential, made with reference to the accompanying drawings in which:
  • Figure 1 is a side view, along a longitudinal sectional plane, of the conduit forming part of a first embodiment of the device according to the invention;
  • Figure 2 is a front view, along the section plane II, of the same device;
  • Figure 3 is similar to Figure 2 and is intended to illustrate the air and water circulation paths inside the duct;
  • Figures 4 to 6 are views respectively similar to Figures 1 to 3 but illustrating the conduit of a second embodiment of the device.

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.

Dans les deux variantes exposées ci-après, les mêmes références numériques seront utilisées pour désigner des éléments identiques ou similaires.In the two variants set out below, the same reference numbers will be used to designate identical or similar elements.

Afin de ne pas alourdir inutilement les figures, le dispositif d'éclairage conforme à l'invention n'a pas été représenté dans son ensemble.In order not to unnecessarily burden the figures, the lighting device according to the invention has not been shown as a whole.

Il s'agit d'un dispositif de type bien connu, comportant un boîtier 1 abritant un miroir de concentration. Au fond du miroir est monté une lampe. Le boîtier reçoit de manière étanche, sur une ouverture frontale, une glace par exemple en matière plastique translucide. Le boîtier et la glace sont scellés l'un à l'autre de manière étanche, par exemple à l'aide d'un joint.It is a well-known type of device, comprising a housing 1 housing a concentration mirror. At the bottom of the mirror is mounted a lamp. The housing receives in a sealed manner, on a front opening, a lens, for example made of translucent plastic. The housing and the glass are sealed together, for example by means of a seal.

Sur la figure 1 annexée est représentée une partie de la paroi de fond 10 du boîtier 1, celui-ci étant réalisé en matière plastique.In the appended FIG. 1 is shown part of the bottom wall 10 of the housing 1, the latter being made of plastic.

Cette paroi est équipée d'un conduit externe 2 qui fait communiquer, comme cela est bien connu, l'intérieur du boîtier avec l'extérieur.This wall is equipped with an external conduit 2 which communicates, as is well known, the interior of the housing with the exterior.

Comme le montre la figure 1, la paroi verticale de ce conduit est formée par la paroi de fond 10 du boîtier. Dans la zone où le conduit communique avec l'intérieur du boîtier, la paroi forme une partie en saillie vers l'intérieur de ce dernier, délimitée par deux portions de paroi 100 et 101. La première 100 est oblique et a une forme concave tandis que la seconde 101 s'étend verticalement vers le haut et parallèlement à la paroi de fond 10 du boîtier.As shown in Figure 1, the vertical wall of this conduit is formed by the bottom wall 10 of the housing. In the zone where the conduit communicates with the interior of the housing, the wall forms a part projecting towards the interior of the latter, delimited by two wall portions 100 and 101. The first 100 is oblique and has a concave shape while that the second 101 extends vertically upwards and parallel to the bottom wall 10 of the housing.

Le conduit 2 s'étend selon une direction générale descendante et présente une ouverture inférieure 20 de largeur sensiblement inférieure à celle du conduit.The conduit 2 extends in a generally descending direction and has a lower opening 20 of width substantially less than that of the conduit.

Le conduit est délimité, comme déjà précisé, au niveau de son fond par la paroi 10. Sa périphérie est formée par une paroi 11 qui s'étend perpendiculairement à la paroi 10 et qui vient de moulage avec elle.The duct is delimited, as already specified, at its bottom by the wall 10. Its periphery is formed by a wall 11 which extends perpendicular to the wall 10 and which comes from molding with it.

Enfin, il est délimité, à l'opposé et parallèlement à la paroi 10, par une paroi de fond 60 d'un bouchon 6, par exemple en matière plastique ou élastomère. Ce bouchon a une forme complémentaire de celle du conduit et s'y adapte parfaitement de façon à le rendre parfaitement étanche.Finally, it is delimited, opposite and parallel to the wall 10, by a bottom wall 60 of a plug 6, for example of plastic or elastomer. This plug has a shape complementary to that of the conduit and adapts perfectly so as to make it perfectly sealed.

Comme le montre la figure 2, le conduit affecte, en vue de face, une forme oblongue qui s'apparente à celle d'un ovale. Le plan médian longitudinal matérialisé par l'axe XY constitue un plan de symétrie.As shown in Figure 2, the duct has, in front view, an oblong shape which is similar to that of an oval. The longitudinal median plane materialized by the XY axis constitutes a plane of symmetry.

Le dispositif comporte un tube débouchant 3 qui est disposé en saillie vers le bas à l'intérieur du conduit.The device comprises a through tube 3 which is arranged projecting downwards inside the duct.

Le tube est formé de deux cloisons parallèles 30, perpendiculaires à la paroi 10 et symétriques l'une de l'autre par rapport à l'axe XY. Ces cloisons viennent de moulage avec le boîtier 1 et s'étendent sur toute l'épaisseur du conduit, jusqu'au bouchon 6.The tube is formed of two parallel partitions 30, perpendicular to the wall 10 and symmetrical to each other with respect to the axis XY. These partitions are molded with the housing 1 and extend over the entire thickness of the conduit, up to the plug 6.

Ce tube s'interrompt au niveau de son extrémité supérieure, à la base de la portion de paroi 100, par une zone de raccordement arrondie 31.This tube is interrupted at its upper end, at the base of the wall portion 100, by a rounded connection zone 31.

Le tube a une section droite plus petite que celle du conduit et les deux cloisons 30 se raccordent chacune aux deux faces latérales parallèles 110 du conduit 2 par les parois de raccordement courbes 31.The tube has a cross section smaller than that of the conduit and the two partitions 30 are each connected to the two parallel lateral faces 110 of the conduit 2 by the curved connection walls 31.

Les espaces C qui sont délimités par les parois ou cloisons 10, 30, 31, 110 et par le bouchon 6, forment des impasses ou des culs de sac. On comprendra plus loin leur intérêt.The spaces C which are delimited by the walls or partitions 10, 30, 31, 110 and by the plug 6, form dead ends or dead ends. We will understand their interest later.

Le dispositif conforme à l'invention comporte, en outre, un élément 4 formant écran. Il est disposé à l'aplomb de l'ouverture inférieure 32 du tube 3 et à distance de celle-ci.The device according to the invention further comprises an element 4 forming a screen. It is arranged directly above and below the lower opening 32 of the tube 3.

Comme le montrent les figures 2 et 3, cet élément a une section droite en forme de "V" avec sa face concave 40 tournée du côté de l'ouverture 20 du conduit 2. Il est constitué par une languette venant de moulage avec le boîtier 1 et s'étendant perpendiculairement à la paroi 10.As shown in Figures 2 and 3, this element has a cross section in the shape of a "V" with its concave face 40 facing the side of the opening 20 of the duct 2. It is constituted by a tongue coming from molding with the housing 1 and extending perpendicular to the wall 10.

La largeur de cet élément est sensiblement voisine de celle du tube 3 et de celle de l'ouverture 20.The width of this element is substantially close to that of the tube 3 and that of the opening 20.

Ce dispositif permet de réaliser une parfaite aération du boîtier puisque l'air peut circuler librement entre l'ouverture 20 du conduit et l'intérieur du boîtier, via l'ouverture 5 (voir double flèche en traits mixtes à la figure 3).This device makes it possible to achieve perfect ventilation of the housing since the air can circulate freely between the opening 20 of the conduit and the interior of the housing, via the opening 5 (see double arrow in phantom in Figure 3).

Par contre, lorsque de l'eau rentre dans le conduit (flèches en traits pointillés), celle-ci est refoulée vers l'ouverture 20 par l'élément 4 formant écran.On the other hand, when water enters the duct (arrows in dotted lines), it is forced back towards the opening 20 by the element 4 forming a screen.

Si de l'eau arrive à passer de part et d'autre de l'élément 4, elle s'engage dans les culs de sac C sans pouvoir progresser plus loin.If water comes to pass on either side of the element 4, it engages in the dead ends C without being able to progress further.

Enfin, lorsque de l'eau arrive à s'engager dans le tube 3, elle ne peut arriver jusqu'à l'intérieur du boîtier du fait de la direction montante de la paroi 100 et de la présence de la paroi 101 formant un muret d'arrêt.Finally, when water arrives to engage in the tube 3, it cannot reach the interior of the housing because of the rising direction of the wall 100 and the presence of the wall 101 forming a low wall stop.

Le mode de réalisation illustré aux figures 4 à 6 a la même structure générale que le précédent mode de réalisation si bien que la description faite pour celui-ci est ici valable. Toutefois, il s'en différencie par le fait que le conduit affecte, en vue de face (voir figure 5) une forme qui s'apparente à celle d'une ellipse. Le plan médian longitudinal matérialisé par l'axe XY constitue un plan de symétrie.The embodiment illustrated in Figures 4 to 6 has the same general structure as the previous embodiment so that the description made for it is valid here. However, it differs from it by the fact that the duct affects, in front view (see FIG. 5) a shape which is similar to that of an ellipse. The longitudinal median plane materialized by the XY axis constitutes a plane of symmetry.

Il s'en distingue également par le fait que dans la zone où le conduit communique avec l'intérieur du boîtier 1, la paroi de ce dernier est dépourvue de saillie.It is also distinguished by the fact that in the area where the conduit communicates with the interior of the housing 1, the wall of the latter is devoid of projection.

Enfin, au niveau de l'ouverture supérieure 33 du tube 3, la paroi de fond 10 comporte une saillie 7 en forme de plaquette qui s'étend entre les cloisons 30. Cette saillie présente la même courbure que les parois de raccordement 31. Elle s'étend seulement sur une partie de l'épaisseur du conduit 2, de façon à laisser entre elle et le bouchon 6, un espace libre.Finally, at the level of the upper opening 33 of the tube 3, the bottom wall 10 has a projection 7 in the form of a plate which extends between the partitions 30. This projection has the same curvature as the connection walls 31. It extends only over part of the thickness of the conduit 2, so as to leave between it and the plug 6, a free space.

Cette saillie forme un muret dont la fonction sera explicitée dans la suite de la description.This projection forms a low wall whose function will be explained in the following description.

Comme dans le précédent mode de réalisation, on réalise une parfaite aération du boîtier puisque l'air peut circuler librement entre l'ouverture 20 du conduit et l'intérieur du boîtier, via l'ouverture 5 (voir double flèche en traits mixtes à la figure 6).As in the previous embodiment, perfect ventilation of the housing is achieved since the air can circulate freely between the opening 20 of the duct and the interior of the housing, via the opening 5 (see double arrow in phantom lines on the figure 6).

Par contre, lorsque de l'eau rentre dans le conduit (flèches en traits pointillés), celle-ci est refoulée vers l'ouverture 20 par l'élément 4 formant écran.On the other hand, when water enters the duct (arrows in dotted lines), it is forced back towards the opening 20 by the element 4 forming a screen.

Si de l'eau arrive à passer de part et d'autre de l'élément 4, elle s'engage dans les culs de sac C sans pouvoir progresser plus loin.If water comes to pass on either side of the element 4, it engages in the dead ends C without being able to progress further.

Enfin, lorsque l'eau arrive à s'engager dans le tube 3, elle ne peut arriver jusqu'à l'intérieur du boîtier du fait que la saillie 7, disposée à l'extrémité supérieure du tube, constitue un muret d'arrêt pour celle-ci.Finally, when the water arrives to engage in the tube 3, it cannot reach the interior of the housing because the projection 7, disposed at the upper end of the tube, constitutes a retaining wall for this one.

Selon une variante de réalisation, l'élément 4 a une section en forme d'arc de cercle avec sa face concave tournée vers l'ouverture 20.According to an alternative embodiment, the element 4 has a section in the form of an arc of a circle with its concave face facing the opening 20.

Dans une autre variante, l'élément formant écran a une largeur voisine de celle du conduit, mais une profondeur plus faible. La position du tube 3 est adaptée en conséquence.In another variant, the screen element has a width close to that of the duct, but a smaller depth. The position of the tube 3 is adapted accordingly.

Selon un autre mode de réalisation, la saillie 7 s'étend entre le passage 5 et le sommet du tube 3. Elle peut se présenter sous la forme d'une plaquette plate.According to another embodiment, the projection 7 extends between the passage 5 and the top of the tube 3. It can be in the form of a flat plate.

Elle pourrait également être disposée au niveau de l'extrémité inférieure du tube 3.It could also be arranged at the lower end of the tube 3.

Du fait que les parois, les cloisons, la saillie et l'écran qui constituent la structure du conduit s'étendent perpendiculairement au fond du boîtier, le moulage de ce conduit se révèle facile à effectuer. Par conséquent, le prix de revient du dispositif ne s'en trouve pas sérieusement affecté.Because the walls, partitions, projection and screen which constitute the structure of the conduit extend perpendicular to the bottom of the housing, the molding of this conduit proves easy to perform. Consequently, the cost price of the device is not seriously affected.
