  "Disque obturateur pour phares à fenêtre centrale lenticulaire etcorps réflecteurs entourant cette fenêtre". 



   Les disques obturateurs pour phares sont construits de telle façon que la lumière incidente du projecteur est réflectée par les prismes,   Cônes   ou lentilles qui entourent une fenêtre du milieu, cependant que dans l'obscurité la lumière du phare tombe par la fenêtre du milieu. Cette fenêtre du milieu est constituée généralement sous forme de lentille   convexe,   les rayons sont par conséquent concentrés et   projetée   à peu près parallèlement à la direction de roulement.

   Il est maintenant de haute importance que la lumière du phare puisse également âtre observée de   cote.   La présente invention concerne par conséquent un disque obturateur, dans 

 <Desc/Clms Page number 2> 

 lequel l'angle de dispersion de la lentille de fenêtre se trouve agrandi, par le fait qu'entre la lentille convexe et les corps réflecteurs il est intercalé des éléments réfractant la lumière avec effet latérale Comme élément de ce genre, la partie entre la lentille de fenêtre et les corps réflecteur. peut, par exemple, être constituée sous forme de lentille concave. 



   L'invention est illustrée à titre d'exemple suivant une forme de réalisation au dessin annexa. 



   Le disque obturateur a, de préférence en verre   comprimée   comporte, de manière usuelle, comme fenêtre du milieu, une lentille convexe b à travers laquelle passent lesrayons du corps éclairant c et parallèlement pour être projetés à la direction de roulement. La couronne entourant la lentille est munie de corps réflecteurs de rayons de genre quelconque tels des   cônes,   lentilles ou miroirs triples d. L'espace entre la lentille b et la couronne réflectrice d eet constitué sous forme de lentille   concave,   par laquelle les rayons de la lampe incandescente sont rendue visibles dans un angle écarté dans la direction de flèches indiquée. 



   Revendications. 



   1. Disque obturateur pour phares à fenêtre centrale lenticulaire et des corps réflecteurs entourant cette fenotre, caractérisé par le fait que pour l'agrandissement de l'angle de dispersion de la lentille fenêtre il est   in-     tercalé   entre cette lentille de fenêtre et les corps ré-   flecteurs   des éléments réfractant la lumière avec effet latéral.

  "Shutter disk for headlights with central lenticular window and reflector bodies surrounding this window".



   Headlight shutter disks are constructed in such a way that incident light from the projector is reflected by prisms, cones or lenses that surround a middle window, while in the dark the light from the headlight falls through the middle window. This middle window is usually made as a convex lens, so the rays are focused and projected roughly parallel to the rolling direction.

   It is now of great importance that the light from the lighthouse can also be seen from the side. The present invention therefore relates to a shutter disc, in

 <Desc / Clms Page number 2>

 which the angle of dispersion of the window lens is enlarged, by the fact that between the convex lens and the reflecting bodies there are interposed elements refracting light with side effect.As such element, the part between the lens window and reflector bodies. can, for example, be constructed as a concave lens.



   The invention is illustrated by way of example according to one embodiment in the accompanying drawing.



   The shutter disc a, preferably of compressed glass, comprises, in a usual manner, as the middle window, a convex lens b through which the rays of the illuminating body c pass and parallel to be projected in the direction of rolling. The crown surrounding the lens is provided with ray-reflecting bodies of any kind, such as cones, lenses or triple mirrors d. The space between the lens b and the reflective crown d eet formed in the form of a concave lens, whereby the rays of the incandescent lamp are made visible at an angle apart in the direction of the arrows indicated.



   Claims.



   1. Shutter disk for headlights with central lenticular window and reflector bodies surrounding this window, characterized in that for the enlargement of the angle of dispersion of the window lens it is interposed between this window lens and the bodies. reflectors of light refracting elements with side effect.


      

Claims (1)

2. Disque obturateur selon la revendication 1, carac- térisé par le fait que dans les corps en verre formés d'une pièce l'espace entre la lentille de fenêtre et les corps réflecteurs est constitué en forme de lentille concave. 2. A shutter disc according to claim 1, characterized in that in glass bodies formed in one piece the space between the window lens and the reflecting bodies is formed in the form of a concave lens.
