Abstract

The indicator has a light source (23) and a reflector (16) positioned behind a colourless cover plate (11), with a filter (18) imparting the required colour to the light beam (27') provided by the source. This filter is arranged so that it is not visible to the other traffic and it may comprise a filter layer applied to the reflective surface of the reflector. The coloured light beam (27,27') leaves the reflector in the direction leading away from the cover plate (11), its direction being reversed via a right angle reflector (22,25). The light source is positioned between a spherical rear reflector and the main reflector (16), the latter lying nearest to the cover plate (11), with a baffle plate (28) to one side.

Description

L'invention a pour objet un indicateur de direction pour véhicules automobiles. The invention relates to a direction indicator for motor vehicles.

Dans les ensembles en unités combinées de phares et feux, la glace de recouvrement de l'indicateur de direction est adjacente à-la glace du phare ou les deux glaces sont réalisées en une seule pièce. La couleur de signalisation jaune du faisceau lumineux est obtenue soit par coloration correspondante de la glace de recouvrement ou au moyen d'un filtre jaune disposé en arrière de la glace de recouvrement. In sets of combined headlights and lamps, the direction indicator cover glass is adjacent to the headlight glass or the two windows are made in one piece. The yellow signaling color of the light beam is obtained either by corresponding coloring of the cover glass or by means of a yellow filter placed behind the cover glass.

Lorsque l'éclairage de route ou de croisement n'est pas en circuit, et lorsque l'indicateur de direction ne fonctionne pas, la glace du phare semble présenter pour les usagers de la route, un brillant métallique ou être argentée tandis que la glace de recouvrement semble jaune. En outre, l'image réfléchie de la lampe à incandescence est visible de l'extérieur. L'impression d'ensemble de la glace plane et largement étendue de l'unité de phares et feux est perturbée, notamment panXla glace de recouvrement jaune. When the high beam or low beam is not on, and when the direction indicator does not work, the headlight glass seems to present to road users, a metallic shine or be silver while the glass cover looks yellow. In addition, the reflected image of the incandescent lamp is visible from the outside. The overall impression of the flat and widely extended glass of the headlight and light unit is disturbed, in particular the yellow cover glass.

L'invention a pour but d'éviter cet inconvénient et concerne à cet effet un indicateur de direction du type ci-dessus caractérisé en ce qu il comprend un réflecteur disposé, avec une source lumineuse, derrière une glace de recouvrement incolore, un filtre donnant au faisceau lumineux réfléchi par le réflecteur la couleur de signalisation prescrite, le filtre étant disposé de manière à ne pas être perceptible par les usagers de la route, et un dispositif dévié sur la glace de recouvrement le faisceau lumineux réfléchi par le réflecteur de façon sensiblement opposée au sens de marche. The object of the invention is to avoid this drawback and to this end relates to a direction indicator of the above type, characterized in that it comprises a reflector arranged, with a light source, behind a colorless covering glass, a filter giving to the light beam reflected by the reflector the prescribed signaling color, the filter being arranged so as not to be perceptible by road users, and a device deflected on the cover glass the light beam reflected by the reflector substantially opposite to the direction of travel.

Avec l'indicateur de direction pour véhicules conforme à l'invention, on obtient, lorsque l'éclairage n'est pas en circuit, un aspect uniforme avec une couleur grise argentée de l'unité à phares et feux. With the direction indicator for vehicles according to the invention, when the lighting is not on, a uniform appearance is obtained with a silver gray color of the headlight unit.

Des dispositions indiquées dans la suite permettent d'obtenir des modes de réalisation avantageux de
I'invention,
L'invention sera mieux comprise en regard de la description ci-après et des dessins annexés représentant deux exemples de réalisation de l'invention, dessins dans lesquels
- la figure 1 est une vue en coupe axiale horizontale d'un indicateur de direction dont le réflecteur comporte une couche filtrante jaune,
- la figure 2 est une vue en coupe axiale horizontale d'un indicateur de direction compact avec une glace filtrante jaune.Arrangements indicated below make it possible to obtain advantageous embodiments of
The invention,
The invention will be better understood with reference to the description below and to the accompanying drawings showing two embodiments of the invention, drawings in which
FIG. 1 is a view in horizontal axial section of a direction indicator, the reflector of which includes a yellow filtering layer,
- Figure 2 is a horizontal axial sectional view of a compact direction indicator with a yellow filter glass.

Un indicateur de direction de gauche comporte une glace de recouvrement incolore 11 comportant sur sa face intérieure des organes optiques 12 et se raccordant à une paroi intérieure 13. Sur cette paroi s'applique un réflecteur 16 dont la surface réfléchissante 17 est pourvue d'une couche filtrante jaune 18 et dont la face arrière 19, dirigée dans le sens de marche suivant la flèche 20, présente un brillant métallique . Un filament 23 appartenant à une lampe à incandescence (non représentée) est disposé au foyer du réflécteur 16 et sur l'axe optique 24. Un miroir sphérique 21 en demi-coquille est disposé de manière à ramener sur eux-mêmes vers le réflecteur 16 les rayons lumineux directs du filament 23. A left-hand direction indicator comprises a colorless covering glass 11 comprising on its inner face optical members 12 and connecting to an inner wall 13. On this wall is applied a reflector 16 whose reflecting surface 17 is provided with a yellow filter layer 18 and whose rear face 19, directed in the direction of travel according to arrow 20, has a metallic shine. A filament 23 belonging to an incandescent lamp (not shown) is placed at the focal point of the reflector 16 and on the optical axis 24. A spherical mirror 21 in half-shell is arranged so as to bring back on themselves towards the reflector 16 the direct light rays of the filament 23.

Un dispositif de déviation de la lumière est constitué par un premier miroir 22 et un second miroir 25 disposés à angle droit et en faisant sensiblement un angle de 45 degrés avec l'axe optique. Un écran 28 évite que les usagers de la route perçoivent la couche filtrante jaune. A light deflection device is constituted by a first mirror 22 and a second mirror 25 arranged at right angles and at substantially an angle of 45 degrees with the optical axis. A screen 28 prevents road users from perceiving the yellow filter layer.

L'indicateur de direction fonctionne comme indiqué ci-après :
Lorsque le filament 23 n'est pas alimenté en courant électrique, la glace de recouvrement 11 apparait aux usagers de la route comme une surface métallique comme la glace voisine. 14 du phare associé et hors circuit 14 (non représenté).The direction indicator works as shown below:
When the filament 23 is not supplied with electric current, the covering glass 11 appears to road users as a metallic surface like the neighboring glass. 14 of the associated headlight and off circuit 14 (not shown).

Cela est dû à l'existence de la face arrière 19, métallique et brillante du réflecteur 16.This is due to the existence of the rear, metallic and shiny face 19 of the reflector 16.

Lorsque le filament 23 est en circuit, les rayons 27 frappant le réflecteur 16 sont réfléchis parallèlement à l'axe optique 24 et les rayons 27 frappant le miroir sphérique 21 sont d'abord réfléchis sur eux-m & es puis, également par le réflecteur 16, parallèlement à'axe optique 24. Le faisceau lumineux ainsi réfléchi 27, 27' reçoit par la couche filtrante jaune 18 la coloration de signalisation prescrite. When the filament 23 is in circuit, the rays 27 striking the reflector 16 are reflected parallel to the optical axis 24 and the rays 27 striking the spherical mirror 21 are first reflected on themselves and then, also by the reflector 16, parallel to the optical axis 24. The light beam thus reflected 27, 27 ′ receives through the yellow filtering layer 18 the prescribed signaling coloration.

Ensuite, le premier miroir 22 dévie le faisceau lumineux 27, 27' de 90 degrés et le second miroir 25 dévie ce faisceau une nouvelle fois de 90 degrés sur les organes optiques de la glace de recouvrement 11 d'où sort finalement le signal prescrit de l'indicateur de direction. Then, the first mirror 22 deflects the light beam 27, 27 ′ by 90 degrees and the second mirror 25 deflects this beam once again by 90 degrees on the optical members of the covering glass 11 from which the prescribed signal from the direction indicator.

L'indicateur de direction représenté sur la figure 2 se distingue de celui de la figure 1 en ce que l'axe optique 24' de la lampe à incandescence 31 est perpendiculaire aux rayons lumineux réfléchis 27 qui reçoivent la coloration de signalisation par passage à travers une glace filtrante jaune 26. Le réflecteur 29 est disposé sur la face extérieure de la paroi intérieure 15 et ne comporte que la surface réfléchissante 17. Ainsi, le réflecteur 29 peut être disposé, en économisant de la place, dans le domaine situé derrière la glace 14 ou le réflecteur 32 du phare voisin. La face arrière du réflecteur 29 n'a pas besoin de présenter un brillant métallique.  The direction indicator shown in Figure 2 differs from that of Figure 1 in that the optical axis 24 'of the incandescent lamp 31 is perpendicular to the reflected light rays 27 which receive the signaling coloration by passage through a yellow filtering glass 26. The reflector 29 is arranged on the outer face of the inner wall 15 and only has the reflecting surface 17. Thus, the reflector 29 can be arranged, saving space, in the area behind the glass 14 or the reflector 32 of the neighboring lighthouse. The rear face of the reflector 29 does not need to have a metallic sheen.
