Abstract

The invention relates to an optical instrument intended for the visual magnification of any object held between the index finger and the thumb to which it is fixed. It consists of a magnifying glass 1 fixed at the end of an articulated arm formed by two elements 2, 3 and comprising, at its other end, a fixing ring 4. This system leaves the hand which carries the magnifying glass free in its movements, thus enabling it to hold the objects to be observed. The device according to the invention is particularly intended for observation of and for work on small-sized objects. Eg: electronics, micromechanics, watchmaking or sewing.

Description

La présente invention concerne un instrument d'optique destiné au grossissement visuel de tous objets maintenus entre l'index et le pouce sur lequel il se fixe. The present invention relates to an optical instrument intended for the visual enlargement of all objects held between the index finger and the thumb on which it is fixed.

Une loupe traditionnelle est équipée d'un bras fixe permettant à l'utilisateur de la maintenir en position devant l'objet à grossir. Avec une loupe de ce type il n'est pas possible de réaliser simultanément les trois opérations suivantes: 1) maintien de l'objet à observer. A traditional magnifying glass is equipped with a fixed arm allowing the user to hold it in position in front of the object to be magnified. With a magnifying glass of this type it is not possible to simultaneously carry out the following three operations: 1) maintaining the object to be observed.

2) maintien de la loupe devant l'objet. 2) holding the magnifying glass in front of the object.

3) intervention sur l'objet. 3) intervention on the object.

La loupe selon l'invention est équipée d'un bras articulé muni à son extrémité d'une bague permettant la fixation de l'instrument au pouce de la main gauche ou droite. Ce système laisse la main qui porte la loupe libre de ses mouvements lui permettant ainsi de maintenir les objets à observer. The magnifying glass according to the invention is equipped with an articulated arm provided at its end with a ring allowing the attachment of the instrument to the thumb of the left or right hand. This system leaves the hand carrying the magnifying glass free to move, allowing it to hold the objects to be observed.

La figure 1 représente en perspective les différents éléments qui composent 11 instrument
La figure 2 représente en perspective l'instrument assemblé.Figure 1 shows in perspective the different elements that make up 11 instruments
Figure 2 shows in perspective the assembled instrument.

La figure 3 représente l'instrument en place sur le pouce. Figure 3 shows the instrument in place on the thumb.

Le dispositif représenté sur la figure 1 comporte une lentille (1) bi-convexe en verre ou matière plastique transparente de l'ordre de 4,5 cm de diamètre, munie sur sa tranche en partie inférieure d'un ergot (2) encastrable dans le bras (3) permettant à la loupe une rotation de 360 degrés. Un bras articulé composé de deux éléments (3.4) de l'ordre de 1,5 cm de longueur permettant le positionnement correct de la loupe devant l'objet à observer. Le bras articulé peut être remplacé par un flexible de même longueur. Une bague de fixation (5) comprenant sur toute sa hauteur une fente de 3 à 4 mm de largeur assurant à la bague la souplesse nécessaire à sa mise en place autour du pouce. Sur sa face intérieure la bague est recouverte d'une couche de mousse souple (7) de 4 mm d'épaisseur environ destinée à assurer une bonne tenue autour du pouce. The device represented in FIG. 1 comprises a bi-convex lens (1) made of glass or transparent plastic material of the order of 4.5 cm in diameter, provided on its edge in the lower part with a lug (2) which can be fitted into the arm (3) allowing the magnifying glass to rotate 360 degrees. An articulated arm composed of two elements (3.4) of the order of 1.5 cm in length allowing the correct positioning of the magnifying glass in front of the object to be observed. The articulated arm can be replaced by a hose of the same length. A fixing ring (5) comprising over its entire height a slot of 3 to 4 mm in width ensuring the ring the flexibility necessary for its positioning around the thumb. On its inner face, the ring is covered with a layer of flexible foam (7) with a thickness of approximately 4 mm intended to ensure good hold around the thumb.

Sur la figure 3 la loupe (1) est positionnée entre l'objet à grossir (8) (ici une aiguille de couturière tenue entre le pouce et l'index) et l'oeil (9). In FIG. 3, the magnifying glass (1) is positioned between the object to be magnified (8) (here a seamstress needle held between the thumb and the index finger) and the eye (9).

Le dipositif selon l'invention est particulièrement destiné à l'ob- servation et à l'intervention sur des objets de petite taille. Ex: Electronique, micro-mécanique, horlogerie, couture.  The device according to the invention is particularly intended for observation and intervention on small objects. Ex: Electronics, micro-mechanics, watchmaking, sewing.
