Abstract

The invention relates to a device enabling the screws of spectacles to be fixed without risk of unscrewing and loss. According to a preferred embodiment, the length of the lower lug of the side 2 or of the tenon of the frame is extended, and in this extra thickness is housed a grub screw which serves to fix the screw-pin 1 of the pivot. The device according to the invention is intended to prevent the screws of spectacles from unscrewing and being lost.

Description

Description
-La présente invention concerne un dispositi! pour éviter le desserrage et la perte des vis qui servent d'articulation et fixation des branches d'une lunette à sa monturc.Description
-The present invention relates to a dispositi! to avoid loosening and loss of the screws which serve as articulation and fixing of the branches of a telescope to its mount.

La fixation traditionnelle s'effectue par.l'intermediare d'une vis-axe, qui se visse à l'oreille inferieure du tenon de la monture,ce qui perte et à cette vis de se desserrer três facilesent et par consequance tomber et se perdre,obligeant à recourir à l'opticien pour son remplacement.The traditional fixing is carried out by the intermediary of a screw-axis, which is screwed to the lower ear of the post of the frame, which loses and this screw to loosen very easy and consequently fall and get lose, forcing the optician to replace it.

Le diEpositif selon l'invention permet de remédier à cet inconvénient.The device according to the invention overcomes this drawback.

Il comporte en effet un systéme de fixation de la ditte vis-axe,ce qui évite le desserrage et la perte de la vis.It indeed includes a system for fixing the said screw-axis, which prevents loosening and loss of the screw.

Selon une forme de réalisation préférentielle,on prolonge la longueur de l'oreille inférieure de la branche et dans cet épaisseur extra on loge une vis sans tête qui sert à fixer la vis-axe.According to a preferred embodiment, the length of the lower ear of the branch is extended and in this extra thickness there is housed a headless screw which serves to fix the screw-axis.

Selon une variante,on laise la longueur traditionnelle et par contre,on prolonge la longueur de la vis-axe de manière a pouvoir visser dans l'e xtrémité qui dépasse une écrou dans laquelle loge une vis sans tête qui sert à fixer la vis-axe.According to a variant, the traditional length is left and on the other hand, the length of the screw-axis is extended so as to be able to screw into the end which exceeds a nut in which a headless screw which serves to fix the screw is housed. axis.

Selon une deuxième variante,on remplace la vis-axe par une tige cylind rioue s-ns filetage oui a une longueur qui dépasse de l'oreille inferieure de la branche.Cette prolongation a une petite gorge où va se loger un anneau avec deux petites vis sans tête qui servent à fixer la tige e t assurer l'ancrage de l'articulation.According to a second variant, the screw-axis is replaced by a cylindrical rod that is threaded without a length that exceeds the length of the lower ear of the branch. This extension has a small groove in which a ring with two small ones will be accommodated. grub screws which serve to fix the rod and secure the articulation.

Selon une troisième variante,la tige de la variante antérieure a une go rge plus profonde où vient se loger une frette métallique à pression qu i sert à fixer la tige et a assurer l'ancrage de l'articulation.According to a third variant, the rod of the previous variant has a deeper groove in which is housed a metal pressure band which i serves to fix the rod and to ensure the anchoring of the joint.
