Abstract

L'invention concerne un dispositif mécanique réglable manuellement, qui intègre un procédé ophtalmique à intensité de lumière variable. Il est constitué de deux supports fixes (lunette partie gauche et lunette partie droite) solidaires chacun d'une lentille polarisée fixe, d'un ressort-fil et d'une glissière circulaire ; de deux supports circulaires tournants (gauche et droit) solidaires chacun d'une lentille polarisée mobile, d'une couronne dentée pour pignon, d'une couronne dentée pour ressort-fil, d'un élément d'arrêt haut pour le ressort-fil, d'un élément d'arrêt bas pour le ressort-fil, d'un crochet haut et d'un crochet bas ; d'un support fixe lunette partie centrale qui incorpore un arbre de transmission ayant deux pignons (gauche et droit) chacun en interaction par engrenage avec la couronnes dentées pour pignon (gauche respectivement droite). Le dispositif selon l'invention est particulièrement destiné aux lunettes de soleil et/ou médicales.The invention relates to a manually adjustable mechanical device which incorporates an ophthalmic process with variable light intensity. It consists of two fixed supports (left part bezel and right part bezel) each secured to a fixed polarized lens, a wire spring and a circular slide; two rotating circular supports (left and right) each secured by a movable polarized lens, a toothed ring for pinion, a toothed ring for wire spring, a high stop element for the wire spring , a bottom stop element for the wire spring, a top hook and a bottom hook; a fixed bezel central support which incorporates a transmission shaft having two pinions (left and right) each interacting by gear with the toothed crowns for pinion (left respectively right). The device according to the invention is particularly intended for sunglasses and / or medical glasses.
