Abstract
Description
L'invention présente, concerne un dispositif pour lunettes, dispositif servant a protéger intégralement les oculaires, des reflets des rayons lumineux du soleil, qui pénètrent entre le visage et la monture ; reflets qui sont une gène pour les yeux et la vue, et qui se traduit par une diminution de la vision du relief. The present invention relates to a device for spectacles, a device serving to fully protect the eyepieces from reflections of the light rays of the sun, which penetrate between the face and the frame; reflections which are a gene for the eyes and the sight, and which results in a reduction in the vision of the relief.
A ce jour, il n'existe aucune solution satisfaisante, connue dans ce domaine. To date, there is no satisfactory solution known in this field.
actuellement, les lunettes, optique ou solaire, pour se protéger de l'intensité des rayons lumineux du soleil et de leurs reflets, sont équipées soit
- d'oculaires teintés dans la masse, qui absorbent principalement, les ultra-violet et les infra-rouge, mais laissent substituer une grande partie des reflets, reflets que cherchent a corriger les revêtements de surface dit anti-reflets - a une couche, ou multicouches.currently, glasses, optical or solar, to protect themselves from the intensity of the light rays of the sun and their reflections, are equipped with either
- mass-tinted eyepieces, which absorb mainly the ultraviolet and infrared rays, but allow a large part of the reflections to be substituted, reflections which seek to correct the so-called anti-reflective surface coatings - for a layer, or multilayer.
- soit par une recherche plus poussée, basée sur l'orientation de cristaux à l'intérieur de la matière dont sont fabriqués les oculaires et qui a pour effet de supprimer les reflets, dans une position orientée - oculaires dit polarisant. - either by further research, based on the orientation of crystals inside the material from which the eyepieces are made and which has the effect of suppressing reflections, in an oriented position - oculars called polarizing.
- soit dans une version encore plus spécifique, qui concerne les lunettes solaires dites de glacier, où les oculaires déjà abondamment traités eux-même, font l'objet d'une protection supplémentaire des rayons et de leurs reflets par l'adjonction de coques latérales, généralement en cuir, parfois en plastique qui enserrent partiellement les oculaires a leurs extrémités, coté tempes. - or in an even more specific version, which concerns so-called glacier sunglasses, where the eyepieces, already abundantly treated themselves, are subject to additional protection from the rays and their reflections by the addition of side shells , usually leather, sometimes plastic which partially enclose the eyepieces at their ends, temple side.
Ce système particulier à l'inconvenient entr'autre de former de véritables oeillères qui réduisent le champ de vision, en supprimant les pcssibilités de vision latérales. This particular system has the drawback, among other things, of forming real blinders which reduce the field of vision, by eliminating the lateral vision possibilities.
Il existe des lunettes dont la monture forme une visière sur le devant de la barre frontale. There are glasses whose frame forms a visor on the front of the front bar.
Ces lunettes ont toutes l'inconvénient de ne pas faire écran aux rayons lumineux ( et à leurs reflets ) qui arrivent sur la face interne des ocu laires en pénétrant entre la monture et le visage - ceci, parce que la monture d'une lunette optique ou solaire n'est pas un masque souple parfaitement adapté au visage, et que des vides subsistent et forment autant d'interstices ou pénètrent les rayons et leurs reflets qui sont cause de la fatioue des yeux et de la diminution de la clarté de vue, donc autant d'inconvénients inconvénients que supprime l'invention qui consiste à inserrer dans toute la partie frontale de la monture et jusqu'aux- branches, une membrane mobile de préférence en cuir souple qui assure une jonction parfaite au visage, faisant un écran total à la luminosité venant d'en haut.Ce résultat est remarquable, encore, parce que l'invention plus efficace que tout autre procédé, pour obstruer les reflets, procure une plus nette clarté du relief, en recréant partellement le phénomème de la vision parfaite du "fond de l'eau" acquise lorsque les reflets de la surface sont supprimés. Test réalisé en regardant au travers d'un masque ajusté qui leur fait écran en pénétrant légèrement dans l'eau. These glasses all have the disadvantage of not shielding the light rays (and their reflections) which arrive on the internal face of the ocu lar by penetrating between the frame and the face - this, because the frame of an optical scope or sunscreen is not a flexible mask perfectly adapted to the face, and that voids remain and form as many interstices or penetrate the rays and their reflections which are the cause of the tiredness of the eyes and the decrease in clarity of view, therefore as many drawbacks drawbacks that the invention which consists in inserting throughout the front part of the frame and up to the temples, a movable membrane preferably of soft leather which ensures a perfect junction to the face, making a total screen to the luminosity coming from above. This result is remarkable, again, because the invention more effective than any other method, for obstructing reflections, provides a clearer relief of the relief, by partially recreating the phé nomème of the perfect vision of the "bottom of the water" acquired when the reflections of the surface are removed. Test carried out by looking through an adjusted mask which screens them by slightly penetrating the water.
L'invention est aussi remarquable par le fait qu'elle obtient les résultats énoncés, sans aucune gène de la vision latérale, et elle est rationnelle dans son efficacité, parce que complémentaire aux techniques actuelles les plus usuelles, qui toujours dans le soucis d'une meilleure vision du relief font que la majorité des oculaires solaires existant sont dégradés et ne filtrent la luminosité que dans leur partie supérieure, celle venant d'en haut. The invention is also remarkable by the fact that it obtains the stated results, without any gene for lateral vision, and it is rational in its effectiveness, because it complements the most common current techniques, which are always concerned with a better vision of the relief means that the majority of existing solar eyepieces are degraded and only filter the brightness in their upper part, that coming from above.
La figure 1 du dessin annexé représente en coupe le dispositif selon itinvention. Figure 1 of the accompanying drawing shows in section the device according to itinvention.
Ce dispositif comporte une membrane frontale souple (1) de préférence en cuir, qui de par sa découpe. déjà appropriée (2) se juxtapose au visage. en sa partie frontale. This device comprises a flexible front membrane (1) preferably made of leather, which by its cut. already appropriate (2) is juxtaposed on the face. in its frontal part.
Le choix du cuir comme matériau lui assure un contact agréable, et la souplesse de la membrane lui permet d'adhérer quelque soit la forme du front. The choice of leather as material ensures a pleasant contact, and the flexibility of the membrane allows it to adhere whatever the shape of the forehead.
La membrane (1) est maintenue fixée à la monture (3) par un support plastique ou métal que représente la figure 2, qui a l'aspect d'une fine lamelle (5) comportant une rainure (7) qui vient se loger dans la rainure des oculaires de la monture, que les oculaires (4) et (5) de la figure 1 maintiennent en place. Cette lamelle s'encastre dans la monture, entre les oculaires, par un évidement de matière, de même, il est possible d'arriver au même résultat par une découpe de la lamelle sur la partie (11) fig 2, qui la relie aux oculaires. The membrane (1) is held fixed to the frame (3) by a plastic or metal support which is shown in Figure 2, which has the appearance of a thin strip (5) having a groove (7) which is housed in the groove of the eyepieces of the frame, which the eyepieces (4) and (5) of FIG. 1 hold in place. This strip is embedded in the frame, between the eyepieces, by a recess of material, similarly, it is possible to achieve the same result by cutting the strip on the part (11) fig 2, which connects it to the eyepieces.
Selon une forme de réalisation préférentielle, la fixation de la membrane frontale (i) å la lamelle (6) est assurée par des rivets (8). According to a preferred embodiment, the fixing of the front membrane (i) to the lamella (6) is ensured by rivets (8).
Toujours dans une réalisation préférentielle, le maintien des extrémités de la membrane frontale est assuré par les passants (9) et (10) qui enserrent chaque branche de la lunette, et confère a la membrane l'elasticité nécessaire en glissant librement sur les branches. Still in a preferred embodiment, the ends of the front membrane are maintained by the loops (9) and (10) which enclose each branch of the telescope, and gives the membrane the necessary elasticity by sliding freely on the branches.
Le dispositif selon l'invention trouve son application dans la fabrication des lunettes de soleil destinées à tous les sports de plein air requérant une meilleure acuité de la vision. The device according to the invention finds its application in the manufacture of sunglasses intended for all outdoor sports requiring better acuity of vision.
