Description

  

  Lunette protectrice contre l'éblouissement par les foyers lumineux intenses.    La circulation nocturne sur les routes  fréquentées par les automobilistes est devenue  très pénible et même dangereuse par suite  de l'emploi par les véhicules, de projecteurs       pulqsants    qui aveuglent les piétons, les cy  clistes, les voituriers et les autres automobi  listes     qui    circulent en sens inverses.  



  Jusqu'ici toute réglementation de ces  éclairages s'est montrée inefficace et incom  patible avec les nécessités de la circulation  des automobiles elles-mêmes.  



       C'est    pourquoi on a songé à protéger les  yeux des usagers de la route par des écrans  en verre fumé ou coloré, ou par des visières.  Mais ces dispositifs     préser,ent    l'inconvénient  de gêner considérablement la vision, soit en  l'obscurcissant encore davantage, soit en en  restreignant     considérablement    le champ.  



  La lunette qui fait l'objet de la présente  invention élimine complètement du champ  visuel la source aveuglante tout en laissant  intégralement visibles les autres parties du  champ.    Cette lunette est caractérisée par ce fait  que sa monture est munie de deux petits  écrans opaques dont un au moins est réglable  en position de manière que l'on puisse par  un mouvement de la tête amener leurs  ombres portées à se former -simultanément  sur la pupille des yeux du porteur.  



  Le dessin annexé montre, à titre d'exem  ple seulement, un mode de réalisation de  l'objet de l'invention.  



  Dans la pratique, comme le montre ce  dessin, les petits écrans opaques 1 recevront  avantageusement la forme de disques circu  laires d'environ 5 à 10 mm de diamètre.  



  Ils pourront être supportés chacun par  deux fils fins 2, 2, tendus horizontalement  dans la monture de la lunette, de manière  qu'ils puissent être déplacés et réglés à la  distance convenable pour que les ombres  portées se forment simultanément sur les  deux pupilles de l'observateur.  



  En général, il n'y a pas lieu de prévoir  un réglage en hauteur.      D'ailleurs; l'un des écrans peut être fixe  dans la monture, l'autre étant seul réglable.  Dans ce cas, il y a avantage à placer l'écran  fixe non au centre; mais légèrement sur le  côté du champ où se trouvent le plus sou  vent les sources éblouissantes, par exemple,  à gauche en France et aux Etats-Unis, vers  la droite, au contraire, dans les pays où les  véhicules tiennent leur gauche.



  Protective glasses against glare by intense light sources. Night traffic on roads frequented by motorists has become very painful and even dangerous as a result of the use by vehicles of pulqsants projectors which blind pedestrians, cyclists, valet drivers and other motorists traveling in the direction of inverse.



  Up to now, any regulation of this lighting has proved ineffective and incompatible with the needs of the circulation of automobiles themselves.



       This is why consideration has been given to protecting the eyes of road users with smoked or colored glass screens, or visors. However, these devices have the disadvantage of considerably hindering vision, either by obscuring it even more or by considerably restricting the field.



  The telescope which is the object of the present invention completely eliminates the blinding source from the visual field while leaving the other parts of the field fully visible. This telescope is characterized by the fact that its frame is provided with two small opaque screens, at least one of which is adjustable in position so that one can by a movement of the head cause their cast shadows to form simultaneously on the pupil. from the wearer's eyes.



  The appended drawing shows, by way of example only, one embodiment of the object of the invention.



  In practice, as shown in this drawing, the small opaque screens 1 will advantageously take the form of circular discs of about 5 to 10 mm in diameter.



  They can each be supported by two fine wires 2, 2, stretched horizontally in the frame of the telescope, so that they can be moved and adjusted to the appropriate distance so that the shadows cast are formed simultaneously on the two pupils of the lens. 'observer.



  In general, there is no need to provide height adjustment. Besides; one of the screens can be fixed in the frame, the other being the only one adjustable. In this case, it is advantageous to place the fixed screen not in the center; but slightly to the side of the field where the dazzling sources are most often found, for example, on the left in France and the United States, to the right, on the contrary, in countries where vehicles keep their left.
