Description
Phare, notamment pour automobile La présente invention a pour objet un phare, no tamment pour automobile, caractérisé par le fait qu'il comporte un réflecteur parabolique à double foyer dont l'un des éléments est équipé d'une ampoule phare tandis que l'autre élément est équipé d'une ampoule code , une glace transparente avant re couvrant ledit réflecteur, le faisceau lumineux de chaque ampoule étant réfléchi par la zone médiane de chaque élément parabolique, et des moyens per mettant de régler la position du réflecteur directe ment de l'extérieur du phare, par l'avant, en hauteur et en direction.
Dans un mode de réalisation de l'invention, les vis de réglage peuvent traverser librement la glace avant et le bord du réflecteur et venir se visser dans des écrous formant rotule, cette disposition évitant la torsion éventuelle des vis lors du réglage.
On va décrire maintenant, à titre d'exemple, deux modes de réalisation de l'invention qui sont représen tés sur le dessin annexé.
Sur ce dessin la fig. 1 est une vue en coupe verticale partielle d'un de ces modes de réalisation ; la fig. 2 est une vue éclatée représentant les élé ments constitutifs du second mode de réalisation ; la fig. 3 est une vue de face du phare réalisé à l'aide des éléments de la fig. 2 ; la fig. 4 est une vue en coupe par IV-IV de la fig. 3 ; la fig. 5 est une vue en coupe par V-V de la fig. 3 ; la fig. 6 est une vue à échelle agrandie de la par tie A encerclée sur la fig. 4.
En se référant au dessin, on voit que dans le mode de réalisation représenté sur la fig. 1, le phare comporte un élément 1 ne réfléchissant que le fais- ceau code . Cet élément est constitué par un peu plus de la moitié supérieure d'un réflecteur parabo lique dont l'ampoule est désignée par 2.
L'élément réflecteur 1 est associé à un second élément réflecteur identique, non représenté, ne ré fléchissant que le faisceau phare , émanant d'une seconde ampoule, également non représentée.
Les éléments 1, de préférence en matière plasti que, comportent des bossages 6 percés d'un trou taraudé et recevant des vis 7 traversant des bossages formés sur le pourtour de la surface transparente avant 8 du phare.
Cette surface 8 pourra être assujettie sur la tôle 9 de la voiture par emboîtement élastique ou par tout autre moyen. Des ressorts 10, interposés entre les bossages 6 et ceux de la partie transparente 8 em pêchent les vibrations et les secousses de la voiture de provoquer tout déplacement du réflecteur 3 par rapport à la partie transparente 8.
Comme on le comprend, les vis 7 permettent d'effectuer le réglage du phare depuis l'avant du véhicule dans le plan vertical et dans le plan hori zontal.
Le mode de réalisation représenté sur les fig. 2 à 6 comprend une collerette 11 fixée à la carrosse rie 9 du véhicule automobile. Dans cette collerette, - qui comporte sur sa face interne des tétons 12, vient s'emboîter, avec interposition d'un joint d'étan chéité 13, le rebord 8a de la partie avant transpa rente 8 du phare.
La solidarisation des pièces 11 et 8-8a est assu rée par engagement des tétons 12 susmentionnés dans des gorges hélicoïdales 14 ménagées dans l'épaisseur du rebord 8a.
La partie avant transparente 8 comporte, sur sa face interne, des bossages 15 percés d'un trou 15a servant au passage de vis 7, l'étanchéité étant assu rée au moyen d'un joint 16. Ces vis, de préférence en matière plastique, sont entourées d'un ressort 10 et viennent s'engager dans des bossages 6 prévus sur le rebord la d'un réflecteur parabolique 1 à double foyer, muni, à sa partie centrale, d'un réflecteur hémisphérique 5 adapté à l'ampoule phare 4 dis posée au-dessous de l'ampoule code 2..
Comme on le comprend, les phares décrits pré sentent les avantages suivants: a) grande facilité de réglage par l'avant ; b) possibilité de retirer l'ensemble : réflecteur 1, partie transparente ou glace 8, sans avoir à démonter quoi que ce soit ; c) possibilité, pour un encombrement déterminé, d'utiliser un réflecteur plus grand, puisque les orga nes constitutifs du dispositif de réglage sont logés à l'intérieur dudit réflecteur.
Headlight, in particular for cars The present invention relates to a headlight, in particular for cars, characterized in that it comprises a parabolic bifocal reflector, one of the elements of which is equipped with a headlight bulb while the another element is equipped with a coded bulb, a transparent front glass covering said reflector, the light beam of each bulb being reflected by the middle zone of each parabolic element, and means for adjusting the position of the reflector directly from the exterior of the lighthouse, from the front, in height and direction.
In one embodiment of the invention, the adjustment screws can pass freely through the front window and the edge of the reflector and come to be screwed into nuts forming a ball joint, this arrangement avoiding the possible twisting of the screws during adjustment.
Two embodiments of the invention will now be described, by way of example, which are shown in the accompanying drawing.
In this drawing, fig. 1 is a partial vertical sectional view of one of these embodiments; fig. 2 is an exploded view showing the constituent elements of the second embodiment; fig. 3 is a front view of the headlight produced using the elements of FIG. 2; fig. 4 is a sectional view through IV-IV of FIG. 3; fig. 5 is a sectional view through V-V of FIG. 3; fig. 6 is an enlarged scale view of part A circled in FIG. 4.
Referring to the drawing, it can be seen that in the embodiment shown in FIG. 1, the headlight comprises an element 1 which reflects only the code beam. This element consists of a little more than the upper half of a parabolic reflector, the bulb of which is designated by 2.
The reflector element 1 is associated with a second identical reflector element, not shown, reflecting only the headlight beam, emanating from a second bulb, also not shown.
The elements 1, preferably of plastic material, comprise bosses 6 pierced with a threaded hole and receiving screws 7 passing through bosses formed on the periphery of the front transparent surface 8 of the headlight.
This surface 8 can be secured to the sheet 9 of the car by elastic interlocking or by any other means. Springs 10, interposed between the bosses 6 and those of the transparent part 8 prevent the vibrations and jolts of the car from causing any movement of the reflector 3 relative to the transparent part 8.
As will be understood, the screws 7 make it possible to adjust the headlight from the front of the vehicle in the vertical plane and in the horizontal plane.
The embodiment shown in FIGS. 2 to 6 comprises a collar 11 fixed to the coach rie 9 of the motor vehicle. In this collar, - which has studs 12 on its internal face, comes to fit, with the interposition of a sealing gasket 13, the rim 8a of the transparent front part 8 of the headlight.
The joining of the parts 11 and 8-8a is ensured by engaging the aforementioned pins 12 in helical grooves 14 formed in the thickness of the rim 8a.
The transparent front part 8 comprises, on its internal face, bosses 15 pierced with a hole 15a serving for the passage of screws 7, the sealing being ensured by means of a gasket 16. These screws, preferably of plastic material. , are surrounded by a spring 10 and come to engage in bosses 6 provided on the rim la of a parabolic reflector 1 with bifocal focus, provided, at its central part, with a hemispherical reflector 5 adapted to the bulb headlight 4 placed below the bulb code 2 ..
As will be understood, the headlights described have the following advantages: a) great ease of adjustment from the front; b) possibility of removing the assembly: reflector 1, transparent part or glass 8, without having to dismantle anything; c) possibility, for a given size, of using a larger reflector, since the constituent organs of the adjustment device are housed inside said reflector.
