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.
