Abstract

Instrument in the form of a bracelet for carrying out currency conversion calculations and additionally any other conversion which can be produced by multiplication or division. It is constituted by two coaxial and juxtaposed rings 7 and 8 assembled together and able to slide in rotation with respect to one another, each comprising a logarithmic graduation 5. After having placed the "1" also physically embodied by an arrow 6 of the graduation of the ring 8 under the graduation of the ring 7 corresponding to the parity of the currency to be converted, the user may carry out conversions by simply reading and taking care to mentally place the decimal points. The instrument according to the invention is essentially worn as a bracelet, on the wrist which serves as its support, and is essentially intended to carry out conversion calculations between various currencies on the basis of their respective exchange rates.

Description

La présente invention concerne un instrument sous forme de bracelet destiné à effectuer des calculs de conversions monétaires. The present invention relates to an instrument in the form of a bracelet intended to perform calculations of currency conversions.

Les touriste, hommes d'affaires et tout voyageur en pays étranger se trouvent couramment confrontés aux problèmes de conversion des prix et valeurs affichés ou donnés en monnaie étrangère. Tourists, businessmen and any traveler in a foreign country are often faced with the problems of converting prices and values displayed or given in foreign currency.

La calculatrice électronique de poche est de nature à résoudre ce problème. Mais son maniement est incommode, contraignant et encombrant pour son utilisateur en station debout, devant une vitrine ou à l'inte- rieur d'un magasin. The electronic pocket calculator is likely to solve this problem. But its handling is inconvenient, restrictive and cumbersome for its user in a standing position, in front of a shop window or inside a store.

L'instrument selon l'invention permet d'apporter une solution à ce-problème tout en se présentant accessoirement sous forme de parure. The instrument according to the invention makes it possible to provide a solution to this problem while being incidentally in the form of adornment.

En effet, cet instrument composé de deux anneaux coaxiaux et juxtaposés comportant chacun une graduation logarithmique présentées l'une face à L'autre, suivant le principe de la règle à calcul, se présente sous forme de bracelet et est destiné à être porté en tant que tel. Cette caractéristique lui permet de servir et d'être disponible à tout instant; en tout lieu et en toute circonstance, depuis l'estivant en tenue de plage jusqu'au skieur encombré de gants, en passant par l'homme d'affaire et le touriste à la recherche ou en butte à un achat ou une transaction.Indeed, this instrument composed of two coaxial and juxtaposed rings each comprising a logarithmic graduation presented one facing the other, according to the principle of slide rule, is in the form of a bracelet and is intended to be worn as as such. This feature allows it to serve and be available at all times; in any place and in any circumstance, from summer vacationers in beach clothes to skiers cluttered with gloves, passing by the businessman and the tourist looking for or coming up against a purchase or transaction.

Après règlage par simple rotation, d'un anneau par rapport à l'autre, sur le cours de la monnaie à convertir, l'utilisateur pourra évaluer instantanément par lecture, avec suffisamment de précision, successivement et sans autre manipulation, les prix affichés dans cette monnaie. After adjustment by simple rotation, from one ring relative to the other, on the course of the currency to be converted, the user will be able to instantly evaluate by reading, with sufficient precision, successively and without any other manipulation, the prices displayed in that currency.

L'instrument selon l'invention est en outre moins vulnérable qu'unc calculatrice électronique de poche, est fiable, ne tombe pas en panne et n'utilise pas de consommables. The instrument according to the invention is also less vulnerable than a pocket electronic calculator, is reliable, does not break down and does not use consumables.

La figure 1 présente la vue de l'instrument dans le sens de son axe. Figure 1 shows the view of the instrument in the direction of its axis.

La figure 2 est une vue perpendiculaire à l'axe de l'instrument
qui fait apparaître la disposition des échelles logarithmiques.Figure 2 is a view perpendicular to the axis of the instrument
which shows the arrangement of the logarithmic scales.

La figure 3 est une coupe d'ensemble suivant A-A. Figure 3 is an overall section along A-A.

La figure 4 est une coupe de détail suivant B-B. Figure 4 is a detail section along B-B.

L'instrument selon l'invention est composé de deux anneaux (7) et (8) de même diamètre, coaxiaux et juxtaposés, respectivement mâle et femelle assemblés et maintenus serrés l'un contre l'autre par emboîtement d'une gorge (1) sur un talon tronconique (2) et pouvant coulisser en rotation l'un par rapport à l'autre. Un vide d'environ lmm. est prévu en (3) pour garantir le contact des deux anneaux en (4).  The instrument according to the invention is composed of two rings (7) and (8) of the same diameter, coaxial and juxtaposed, respectively male and female assembled and kept tight against each other by fitting a groove (1 ) on a frusto-conical heel (2) and able to slide in rotation relative to one another. A vacuum of around 1mm. is provided in (3) to guarantee the contact of the two rings in (4).

\ Dans sa forme d'exécution préférentielle, le diamètre intérieur de l'instrument se situera entre 6 et 9 cm pour permettre la réalisation de modèles enfants, femmes et hommes et le section sera de l'ordre de 4 x 16 mm. \ In its preferred embodiment, the internal diameter of the instrument will be between 6 and 9 cm to allow the realization of children's, women's and men's models and the section will be of the order of 4 x 16 mm.

L'instrument pourra être réalisé par usinage au tour ou par moulage, en matière plastique, alliages légers ou métaux précieux selon les versions économiques ou luxueuses dans lesquelles il pourra être commercialisé simultanément. La matérialisation des graduations logarithmiques C5) pourra être réalisé par gravures, par impression ou par moulage. The instrument can be produced by lathe machining or by molding, in plastic, light alloys or precious metals depending on the economic or luxury versions in which it can be marketed simultaneously. The materialization of the logarithmic graduations C5) can be achieved by engravings, by printing or by molding.

Pour effectuer des calculs de conversions, l'utilisateur procèdera (6) d'abord à un règlage de l'instrument en plaçant la flèche. e la graduation de l'anneau (8) face à la position sur la graduation de l'anneau (7) correspondant à la parité de la monnaie à convertir. To perform conversion calculations, the user will first (6) adjust the instrument by placing the arrow. e the scale of the ring (8) opposite the position on the scale of the ring (7) corresponding to the parity of the currency to be converted.

L'utilisateur pourra ensuite effectuer par simple lecture les conversions en prenant soin de placer mentalement les décimales. La graduation de l'anneau (8) représentant les prix ou valeurs en monnaie étrangère face auxquels il lira sur la graduation de 11 anneau (7) les prix correspondants en monnaie de son pays. The user can then perform the conversions by simple reading, taking care to place the decimals mentally. The graduation of the ring (8) representing the prices or values in foreign currency against which he will read on the graduation of 11 ring (7) the corresponding prices in the currency of his country.

Pour faciliter la lecture et éviter les confusions, les deux anneaux seront l'un par rapport à l'autre - ou les graduations l'une par rapport à l'autre - de teinte différente. To facilitate reading and avoid confusion, the two rings will be in relation to each other - or the graduations in relation to each other - of different colors.

L'instrument selon l'invention est destiné à effectuer des calculs de conversions monétaires et accessoirement toute autre conversion ou opération réalisable par simple multiplication ou division.  The instrument according to the invention is intended to perform calculations of monetary conversions and incidentally any other conversion or operation that can be carried out by simple multiplication or division.
