Description

GLACE DE BLOC OPTIQUE ET BLOC OPTIQUE COMPORTANT UNE  OPTICAL BLOCK ICE AND OPTICAL BLOCK COMPRISING A
TELLE GLACE  SUCH ICE
L'invention concerne les glaces (ou vitres) de blocs optiques, et 5 notamment les glaces qui protègent les dispositifs d'éclairage et/ou de signalisation de véhicules, notamment de véhicules automobiles. The invention relates to windows (or windows) of optical blocks, and in particular to windows that protect the lighting and / or signaling devices of vehicles, especially motor vehicles.
On notera que l'on entend ici par « bloc optique » aussi bien un projecteur qu'un feu.  Note that here is meant by "optical block" both a projector and a fire.
Les glaces des blocs optiques, notamment des projecteurs avant, î o présentent généralement des faces avant planes plus ou moins galbées pour s'adapter à la partie ou face avant du véhicule.  The windows of the optical blocks, in particular front projectors, generally have flat front faces that are more or less curved to fit the front part of the vehicle.
Cette glace avant affleure généralement les éléments de carrosserie qui l'entourent et/ou la supporte comme le capot, les ailes ou le pare-chocs.  This front window is generally flush with the bodywork elements that surround it and / or supports it such as the hood, the wings or the bumper.
La face avant est l'une des parties les plus visibles du véhicule. Elle 15 participe donc à la signature visuelle d'une marque qui doit se distinguer de celle des autres marques.  The front is one of the most visible parts of the vehicle. It therefore participates in the visual signature of a mark that must be distinguished from that of other brands.
La réalisation d'une glace doit répondre à un certain nombre de contraintes dont les contraintes mécaniques induites par l'exposition de la face avant du véhicule et donc de ses blocs optiques vis-à-vis notamment 20 des chocs frontaux s'agissant de projecteurs, et notamment des chocs à faible vitesse qui peuvent être nombreux et répétés notamment en milieu urbain.  The production of an ice cream must meet a certain number of constraints, including the mechanical stresses induced by the exposure of the front face of the vehicle and therefore of its optical units with respect to frontal shocks in the case of projectors. , and in particular low-speed shocks that can be numerous and repeated, particularly in urban areas.
Une telle glace doit donc répondre à une double contrainte : participer à l'effet esthétique soulignant l'identité de la marque du véhicule et 25 permettre une réparabilité en cas de bris de verre suite à un choc.  Such ice cream must therefore meet a double constraint: to participate in the aesthetic effect emphasizing the identity of the make of the vehicle and to allow repairability in the event of breakage of glass following an impact.
L'invention a donc pour but de proposer une glace répondant de manière avantageuse à cette double contrainte.  The object of the invention is therefore to propose an ice which advantageously meets this double constraint.
Elle propose notamment à cet effet une glace apte à fermer un boîtier de bloc optique, ladite glace présentant une face extérieure orientée 30 vers l'extérieur d'un véhicule quand le bloc optique est monté sur le véhicule, caractérisée en ce que la face extérieure de la glace est conformée pour présenter une partie longiligne venue de matière avec la glace et se prolongeant au-delà de la face extérieure de la glace pour définir une partie libre faisant saillie de la glace, ladite partie longiligne étant apte à être solidarisée au boîtier par au moins un premier élément de fixation sécable venu de matière avec la partie longiligne. For this purpose, it proposes an ice capable of closing an optical block housing, said mirror having an outer face oriented towards the outside of a vehicle when the optical unit is mounted on the vehicle, characterized in that the outer face ice is shaped to present an elongated part of material with the ice and is extending beyond the outer face of the ice to define a free portion projecting from the ice, said elongate portion being adapted to be secured to the housing by at least a first breakable fastener integrally formed with the elongate portion.
5 Selon une caractéristique, la partie longiligne est réalisée par injection bi-matière ou surmoulage de telle manière que les faces latérales de la partie longiligne apparaissent en noir.  According to one feature, the elongate portion is made by bi-material injection molding or overmolding so that the side faces of the elongate portion appear black.
Selon une autre caractéristique, la partie longiligne est en surépaisseur de la face extérieure de la glace et empiète sur ladite face, î o La présente invention a pour autre objet un bloc optique comportant une glace telle qu'introduite ci-dessus ; ladite glace fermant le boîtier du bloc optique.  According to another feature, the elongated portion is in excess of the outer face of the ice and encroaches on said face. The present invention has another object an optical block comprising an ice as introduced above; said ice closing the housing of the optical unit.
Selon une caractéristique du bloc optique, la partie longiligne est disposée devant une fonction d'éclairage et/ou de signalisation distincte de i 5 celle hébergée dans le boîtier.  According to one characteristic of the optical unit, the elongate portion is arranged in front of a lighting and / or signaling function distinct from that housed in the housing.
Selon une autre caractéristique, la fonction d'éclairage est une fonction d'éclairage de type DRL.  According to another characteristic, the lighting function is a DRL type lighting function.
La présente invention a pour autre objet un véhicule comportant un pare-chocs et au moins un bloc optique tel qu'introduit ci-dessus ; ledit pare- 20 chocs comportant une échancrure aménagée dans un des bords du pare- chocs affleurant la partie inférieure du bloc optique et recevant la partie longiligne de la glace ; la partie libre de la partie longiligne comportant en outre des deuxième et troisième éléments de fixation sécables fixant la partie libre au pare-chocs et formant avec le premier élément de fixation une zone 25 de fixation isostatique de la partie longiligne sur le boiter et sur le pare-chocs.  Another object of the present invention is a vehicle comprising a bumper and at least one optical unit as introduced above; said bumper having a notch formed in one of the edges of the bumper flush with the lower portion of the optical unit and receiving the elongate portion of the ice; the free portion of the elongated portion further comprising second and third breakable fastening elements fixing the free portion to the bumper and forming with the first fastener an isostatic fastening zone 25 of the elongated portion on the limp and on the bumper.
Selon une caractéristique du véhicule, un enjoliveur est rapporté dans ou sur l'échancrure du pare-chocs de manière à masquer les éléments de fixation sécables de la partie longiligne et apte à permettre la réparabilité de la partie longiligne à la suite de la casse de la partie longiligne.  According to a characteristic of the vehicle, a hubcap is attached in or on the indentation of the bumper so as to mask the breakable fastening elements of the elongated portion and adapted to allow the repairability of the elongated portion following the breakage of the elongated part.
30 Selon une autre caractéristique, l'enjoliveur est abouté au boîtier du bloc optique par soyage. According to another characteristic, the hubcap is butted to the casing of the optical block by squelching.
La présente invention a pour autre objet, un pare-chocs destiné à équiper un véhicule tel qu'introduit ci-dessus, ledit pare-chocs comportant une échancrure aménagée dans un des bords du pare-chocs et étant apte à affleurer la partie inférieure du bloc optique et à recevoir la partie longiligne de la glace. The present invention has another object, a bumper for equipping a vehicle as introduced above, said bumper comprising an indentation formed in one of the edges of the bumper and being able to be flush with the lower part of the optical block and receive the elongated portion of the ice.
La présente invention a pour avantage de renforcer l'identité d'un 5 véhicule, en proposant un motif sortant du volume du projecteur.  The present invention has the advantage of enhancing the identity of a vehicle by providing a pattern out of the volume of the projector.
Elle apporte par ailleurs une solution simple et peu coûteuse à la réparabilité du projecteur ainsi constitué qui comporte une extension de sa glace qui fait saillie du projecteur et qui donc, par construction, est fragile.  It also provides a simple and inexpensive solution to the repairability of the projector thus formed which has an extension of its ice projecting from the projector and therefore, by construction, is fragile.
D'autres caractéristiques et avantages de l'invention apparaîtront à î o l'examen de la description détaillée ci-après, et des dessins annexés, sur lesquels :  Other characteristics and advantages of the invention will emerge on examining the detailed description below, and the appended drawings, in which:

20 - la figure 4 illustre schématiquement un enjoliveur rapporté sur sur le pare- chocs en interface avec la glace du projecteur.  FIG. 4 schematically illustrates a hubcap attached to the bumper in interface with the projector lens.
On considère dans ce qui suit, à titre d'exemple non limitatif, un projecteur de véhicule automobile destiné à être installé à l'avant d'un véhicule, éventuellement de type automobile. Mais, l'invention n'est pas 25 limitée à ce type d'implantation. Elle concerne également certains dispositifs destinés à être installés à l'arrière d'un véhicule, éventuellement de type automobile.  In the following, by way of nonlimiting example, a motor vehicle headlamp intended to be installed at the front of a vehicle, possibly of automobile type, is considered below. However, the invention is not limited to this type of implantation. It also relates to certain devices intended to be installed at the rear of a vehicle, possibly of the automotive type.
En outre, on considère dans ce qui suit, à titre d'exemple non limitatif, que l'extension de la glace, en saillie de la face avant de la glace, 30 est destinée à protéger une fonction dite DRL (pour "Daytime running Light (or Lamp)" - signalisation lumineuse allumée automatiquement lorsque le véhicule se met à avancer). Mais, l'invention n'est pas limitée à cette application lorsqu'elle concerne un véhicule. Ainsi, elle concerne également, et notamment, la fonction de feu de position (ou veilleuse ou encore lanterne) ou la fonction d'indicateur de direction. In addition, it is considered in the following, by way of non-limiting example, that the extension of the ice, projecting from the front face of the ice, 30 is intended to protect a so-called DRL function (for "Daytime running Light (or Lamp) "- illuminated warning light automatically when the vehicle starts to move forward). But, the invention is not limited to this application when it relates to a vehicle. So, it also concerns, and in particular, the position light function (or pilot or lantern) or the direction indicator function.
On notera que l'on entend ci-après par "partie ou face avant", une partie ou face qui est orientée vers l'extérieur du véhicule et, s'agissant d'un 5 projecteur et de la face ava nt de la glace du projecteur, la face qui est orientée vers l'avant du véhicule.  It should be noted that hereinafter "part or front face" is understood to mean a part or face which faces the outside of the vehicle and, being a headlamp and the front side of the ice of the headlamp, the side facing the front of the vehicle.
On a illustré schématiquement sur la figure 1 , un mode de réalisation, non limitatif, d'un projecteur 10 monté à l'avant d'un véhicule automobile V comprenant un boîtier 20 fermé par une glace 30 selon î o l'invention, disposé entre le pare-chocs avant 40 et une partie de carrosserie (aile ou capot) 70.  FIG. 1 schematically illustrates a non-limiting embodiment of a headlamp 10 mounted at the front of a motor vehicle V comprising a housing 20 closed by an ice-cream 30 according to the invention, arranged between the front bumper 40 and a body part (wing or bonnet) 70.
Il est rappelé qu'un projecteur de véhicule comprend généralement un boîtier auquel sont solidarisés un masque, un éventuel réflecteur, et une glace qui est placée devant le réflecteur ainsi qu'éventuellement devant le 15 masque.  It is recalled that a vehicle headlamp generally comprises a housing to which a mask, a possible reflector and an ice-cream which is placed in front of the reflector as well as possibly in front of the mask are secured.
Le boîtier définit au moins une cavité ouverte qui loge le masque, l'éventuel réflecteur et au moins un dispositif d'éclairage et/ou de signalisation comportant par exemple une ou plusieurs ampoules ou encore une ou plusieurs diodes électroluminescentes (LEDs).  The housing defines at least one open cavity which houses the mask, the optional reflector and at least one lighting and / or signaling device comprising for example one or more bulbs or one or more light-emitting diodes (LEDs).
20 Pour simplification des figures, le masque, le réflecteur et le dispositif d'éclairage ne sont pas représentés. For simplicity of the figures, the mask, the reflector and the lighting device are not shown.
Dans le mode de réalisation illustré schématiquement à la figure 1 , la glace 30 comporte une face avant 31 conformée pour présenter une partie longiligne 32 ou barrette, apte à protéger une fonction d'éclairage et/ou de 25 signalisation du dispositif d'éclairage et/ou de signalisation distincte ou pas des autres fonctions d'éclairage et/ou de signalisation hébergées dans le boîtier 20 du projecteur 10.  In the embodiment illustrated schematically in FIG. 1, the window 30 has a front face 31 shaped to have an elongate portion 32 or strip, able to protect a lighting and / or signaling function of the lighting device and and / or separate signaling or not other lighting and / or signaling functions housed in the housing 20 of the projector 10.
La partie longiligne 32 s'étend au-delà de la face avant 31 de la glace 30 en faisant saillie du projecteur 10 vers le pare-chocs avant 40.  The elongated portion 32 extends beyond the front face 31 of the lens 30 projecting from the projector 10 to the front bumper 40.
30 Elle est venue de matière avec la glace 30 du projecteur 10, typiquement réalisée à partir d'un polycarbonate. It is made of material with the mirror 30 of the projector 10, typically made from a polycarbonate.
Sur la figure 3, on a représenté à l'intérieur d'une zone délimitée par une ligne fermée discontinue, les éléments de fixation sécables de la partie longiligne 32 vus par transparence artificielle du pare-chocs 40 et du boîtier 20 du projecteur. In FIG. 3, there is shown inside a zone delimited by a discontinuous closed line, the breakable fastening elements of the part slender 32 seen by artificial transparency of the bumper 40 and the housing 20 of the projector.
La partie supérieure 33 de la partie longiligne 32 est solidarisée au boîtier 20 par un élément de fixation sécable 34 réalisé par exemple par une 5 patte de fixation, venue de matière avec la partie supérieure 33 de la partie longiligne. La patte 34 comporte des zones à amorce de rupture, non représentées, obtenues par des diminutions locales d'épaisseur prenant la forme, par exemple, d'un segment de droite en pointillés.  The upper portion 33 of the elongated portion 32 is secured to the housing 20 by a breakable fastener 34 made for example by a fastening lug, integral with the upper portion 33 of the elongated portion. The tab 34 comprises zones with rupture initiation, not shown, obtained by local decreases in thickness taking the form, for example, of a line segment in dashed lines.
Un trou de fixation est percé dans la patte 34 pour le passage d'une î o vis de fixation non représentée. La patte 34 est fixée par l'intérieur du véhicule V et n'est donc pas visible de l'extérieur.  A fixing hole is drilled in the lug 34 for the passage of a fastening screw not shown. The tab 34 is fixed by the interior of the vehicle V and is therefore not visible from the outside.
Deux autres pattes de fixation sécables, similaires à la première patte 34, respectivement référencées 35 et 36, et venues de matière avec la partie libre 37 de la partie longiligne 32, sont aménagées de part et d'autre 15 de l'extrémité libre 37 de la partie longiligne 32. Elles maintiennent la partie libre 37 contre le pare-chocs 40 et sont aptes à se rompre en cas de choc frontal.  Two other breakable fastening tabs, similar to the first tab 34, respectively referenced 35 and 36, and integral with the free portion 37 of the elongated portion 32, are arranged on either side of the free end 37 of the elongated portion 32. They maintain the free portion 37 against the bumper 40 and are capable of breaking in the event of a frontal impact.
Un trou de fixation est percé dans chacune des pattes 35 et 36 pour permettre le passage d'une vis de fixation non représentée. Les pattes 35 et 20 36 sont fixées au pare-chocs par l'intérieur du pare-chocs et ne sont donc pas visibles de l'extérieur.  A fixing hole is drilled in each of the tabs 35 and 36 to allow the passage of a not shown fastening screw. The tabs 35 and 36 are fixed to the bumper by the interior of the bumper and are therefore not visible from the outside.
Les trois fixations 34 à 36 sont agencées de manière à définir une fixation isostatique de la partie longiligne 32.  The three fasteners 34 to 36 are arranged to define an isostatic attachment of the elongated portion 32.
Le bord supérieur 41 du pare-chocs 40 comporte une échancrure 42 25 (Figure 1 ) aménagée de manière à épouser la partie visible de la partie longiligne 32.  The upper edge 41 of the bumper 40 has a notch 42 25 (Figure 1) arranged to fit the visible part of the elongate portion 32.
La partie longiligne 32 comporte une face extérieure 321 (Figure 2) de largeur déterminée, destinée à rester visible de l'extérieur du véhicule V et donc de l'avant du véhicule V quand le pare-chocs 40 est monté sous le 30 projecteur 10.  The elongated portion 32 has an outer face 321 (Figure 2) of a predetermined width, intended to remain visible from the outside of the vehicle V and therefore the front of the vehicle V when the bumper 40 is mounted under the projector 10 .
La partie longiligne 32 comporte également une base 322 définissant deux joues 323 et 324, non visibles de l'extérieur, et agencées de part et d'autre de la face visible 321 . Cette base 322 vient s'abouter à une partie désignée par les termes « pied de glace » 325 du projecteur 10, qui définit une butée destinée classiquement à recevoir le bord supérieur 41 du pare-chocs avant 40 en affleurant la partie inférieure 326 de la glace 30. Le pied de glace 325 désigne également la zone de recul de pare-chocs 40 5 prévue pour absorber les faibles déplacements en « X » du pare-chocs 40 en cas de petits chocs à l'avant notamment lors de manœuvre de parcage. The elongated portion 32 also comprises a base 322 defining two cheeks 323 and 324, not visible from the outside, and arranged on either side of the visible face 321. This base 322 comes to add to a part designated by the terms "foot of ice" 325 of the headlamp 10, which defines an abutment conventionally intended to receive the upper edge 41 of the front bumper 40 flush with the lower portion 326 of the ice 30. The foot of ice 325 designates also the bumper recoil zone 40 5 designed to absorb the small movements in "X" of the bumper 40 in case of small shocks to the front especially during parking maneuver.
Un enjoliveur 60 est rapporté dans et/ou sur l'échancrure 42 du pare-chocs 40 (Figure 3) de manière à masquer les pattes de fixation sécables 34 à 36 et apporter une finition esthétique à la face avant du î o véhicule V.  A hubcap 60 is attached to and / or on the notch 42 of the bumper 40 (Figure 3) so as to mask the breakable fastening tabs 34 to 36 and provide an aesthetic finish to the front of the vehicle I.
La solidarisation de l'enjoliveur 60 sur le pare-chocs 40 peut être faite par clippage dans un moyen de clippage correspondant du pare-chocs 40 (par exemple défini dans un logement), ou bien par vissage par l'intérieur du pare-chocs 40.  The fastening of the trim 60 on the bumper 40 may be made by clipping into a corresponding clipping means of the bumper 40 (for example defined in a housing), or by screwing from the inside of the bumper 40.
15 Le clippage de l'enjoliveur 60 sur le bord inférieur de la glace 30 à la jonction entre la partie supérieure 33 et le bord inférieur de la glace 30, au voisinage de la partie supérieure 33 de la partie longiligne 32, est réalisé par exemple par soyage en profitant de la zone bicolore obtenue par surmoulage et/ou injection bi matière : obtention d'une zone sombre voire noire entourant The clipping of the trim 60 on the lower edge of the ice 30 at the junction between the upper part 33 and the lower edge of the ice 30, in the vicinity of the upper part 33 of the elongate part 32, is produced for example by jogging taking advantage of the two-color zone obtained by overmolding and / or bi-material injection: obtaining a dark or even dark zone surrounding
20 les bords périphériques de la glace 30 et les faces latérales de la partie longiligne 32. The peripheral edges of the ice 30 and the lateral faces of the elongated portion 32.
De la même manière avantageuse, l'élément sécable 34 est agencé de préférence dans une zone de couleur « noire » du boîtier 20 pour réduire son impact visuel.  In the same advantageous manner, the breakable element 34 is preferably arranged in a "black" color zone of the housing 20 to reduce its visual impact.
25 En cas de cassure de la partie longiligne 32, une procédure doit être engagée sans pour cela devoir remplacer le projecteur 10 dans son ensemble. En effet, la partie longiligne 32 est celle qui par construction, est la plus exposée à un choc frontal et il serait dommageable pour l'image de marque du constructeur de ne pas prévoir une procédure de réparabilité en 30 garage à un coût réduit.  In case of breakage of the elongate portion 32, a procedure must be initiated without having to replace the projector 10 as a whole. Indeed, the elongated portion 32 is the one that by construction is most exposed to a frontal impact and it would be harmful for the brand image of the manufacturer not to provide a garage repair procedure at a reduced cost.
La procédure de réparabilité se déroule de la manière suivante : Les éléments sécables 34 à 36 assurent une cassure nette à la jonction entre d'une part, la partie supérieure 33 de la partie longiligne 32 et le bord inférieur du boîtier 20 et, d'autre part, entre la partie libre 37 de la partie longiligne 32 et le pare-chocs 40. The reparability procedure takes place as follows: The breakable elements 34 to 36 provide a clean break at the junction between, on the one hand, the upper part 33 of the elongated part 32 and the lower edge of the housing 20 and, on the other hand, between the free portion 37 of the elongate portion 32 and the bumper 40.
Suite à un choc frontal ayant entraîné la rupture nette de la partie longiligne 32, on effectue le remplacement de cette partie cassée par une 5 nouvelle partie longiligne identique à la précédente.  Following a frontal impact having caused the clear rupture of the elongate portion 32, the replacement of this broken part by a new longiline part identical to the previous one.
La partie supérieure 33 de la nouvelle partie longiligne 32 est aboutée au bord inférieur du boîtier 20 et fixée au boîtier 20 via la patte de fixation 34.  The upper portion 33 of the new elongated portion 32 is abutted at the lower edge of the housing 20 and fixed to the housing 20 via the bracket 34.
Et dans le même temps, les deux autres pattes de fixation 35 et 36 î o sont fixées au pare-chocs 40.  And at the same time, the two other fastening tabs 35 and 36 are attached to the bumper 40.
L'enjoliveur 60 est ensuite chaussé sur les joues 323 et 324 de la partie longiligne 32 et fixé par clippage ou vissage sur le pare-chocs 40.  The hubcap 60 is then shod on the cheeks 323 and 324 of the elongated portion 32 and fixed by clipping or screwing on the bumper 40.
Entre temps, on aura pu intervenir sur la fonction d'éclairage et/ou de signalisation, protégée par la partie longiligne 32, par exemple en cas de 15 changement des LEDs de la fonction DRL.  Meanwhile, it has been possible to intervene on the lighting function and / or signaling, protected by the elongate portion 32, for example in case of 15 LEDs change of the DRL function.
La glace 30 et sa partie longiligne 32 sont réalisées par injection bi- matière ou surmoulage de telle manière que les faces latérales de la partie longiligne 32 qui sont visibles de l'extérieur apparaissent en noir.  The ice 30 and its elongated portion 32 are made by bi-material injection molding or overmolding so that the side faces of the elongated portion 32 which are visible from the outside appear black.
A titre de variante, la partie longiligne 32 peut présenter une 20 surépaisseur par rapport à la face extérieure 31 de la glace 30 et empiéter sur la face avant 31 de la glace 30.  Alternatively, the elongated portion 32 may have an extra thickness with respect to the outer face 31 of the ice 30 and encroach on the front face 31 of the ice 30.
Dans cette variante, l'enjoliveur 60 pourra s'étendre sur toute la longueur des parties latérales (qui correspondraient aux joues 323 et 324 du mode de réalisation de la figure 2) de la partie longiligne 32, évitant ainsi 25 l'utilisation du soyage et améliorant par la même la qualité des jeux et affleurements de l'ensemble constitué par la partie longiligne en excroissance sur la glace et de l'enjoliveur rapporté sur cette excroissance.  In this variant, the hubcap 60 may extend over the entire length of the lateral parts (which correspond to the cheeks 323 and 324 of the embodiment of FIG. 2) of the elongated part 32, thus avoiding the use of the sinking and thereby improving the quality of the games and outcrops of the assembly consisting of the elongated portion outgrowth on the ice and hubcap reported on this outgrowth.
