Abstract

The device has a plate (1) that is provided for receiving a desired decoration (2). A deformable ring is fixed to the plate by a connection unit integrated to the plate. The deformable ring is constituted by a joined coil spring (5) having a specific elasticity. The connection unit comprises receptacles (3, 4) fixed on both sides of the plate and provided for receiving ends of the spring, respectively. The length of the spring is such that the diameter of the ring corresponds to that of user`s smallest finger wearing the ring, when the spring is fixed to the plate.

Description

La présente invention destinée à la bijouterie et la joaillerie concerneThe present invention for jewelery and jewelery concerns

un dispositif pour la réalisation de bagues, qui procure un 'ajustement de ces bagues pur leur permettre de s'adapter aux doigts destines à les poiler d'une o, a device for the production of rings, which provides an adjustment of these rings to allow them to adapt to the fingers intended to coat an o,

manière facile et sans sacrifier à l'esthétique du bijou. easy way and without sacrificing to the aesthetics of the jewel.

Faute d'un tel ajustement, il est nécessaire de fabriquer, de stocker et de commercialiser les bagues selon de nombreuses dimensions, ce qui augmente les coût4..s et 4 crée des contraintes de 4r Ll... de disponibilité sur l....es lieux d..e vente. In the absence of such an adjustment, it is necessary to manufacture, store and market the rings in many dimensions, which increases the costs 4 .. and 4 creates constraints of 4r LL availability ... ..the places of sale.

Les dispositifs déjà imaginés à cette fin comprennent des mécanismes délicats, peu faciles à manier par les vendeurs et par les utilisatrices, et qui, de surcroît, ne satisfont pas les objectifs d'esthétique souhaitables. Ils ne sont pas suffisamment satisfaisants pour en permettre la commercialisation, notamment dans le domaine de la bijouterie de luxe. Devices already devised for this purpose include delicate mechanisms, not easy to handle by sellers and users, and which, moreover, do not meet the desired aesthetic objectives. They are not satisfactory enough to allow commercialization, especially in the field of luxury jewelery.

Le dispositif selon l'invention allie l'efficacité à la simplicité de leur utilisation et participe d'une manière positive à l'esthétique et à l'originalité des 20 bagues qui en sont dotées. The device according to the invention combines efficiency with the simplicity of their use and contributes positively to the aesthetics and originality of the rings that have them.

Dans une première forme de réalisation, il comprend un ressort à spires jointives, dont chaque spire présente une forme appropriée à l'aspect souhaité du bijou, et les moyens d'en fixer les extrémités de part et d'autre du plateau de la bague destiné à supporter toute décoration artistique souhaitée. In a first embodiment, it comprises a spring with contiguous turns, each turn of which has a shape appropriate to the desired appearance of the jewel, and the means of fixing the ends on either side of the ring plate. intended to support any desired artistic decoration.

Le plateau du bijou est doté de part et d'autre d'un réceptacle et d'un mode d'arrimage destiné à recevoir et fixer les extrémités dudit ressort. Une fois ainsi fixé, le ressort prend naturellement la forme d'un anneau bague classique. The tray of the jewel is provided on either side of a receptacle and a stowage mode for receiving and fixing the ends of said spring. Once thus fixed, the spring naturally takes the form of a conventional ring ring.

Lors de la mise en place de la bague sur un doigt, l'élasticité du ressort est telle que le ressort en s'allongeant ne fait peser qu'une légère pression répartie sur tout le pourtour du doigt sans occasionner de gêne au porteur. When setting up the ring on a finger, the elasticity of the spring is such that the spring lengthens only a slight pressure spread over the entire circumference of the finger without causing discomfort to the wearer.

Dans une forme de réalisation, le ressort comprend 100 spires jointives réalisées en fil poli INOX de caractéristiques convenablement choisies et de diamètre 0, 5 mm. Ce ressort est fabriqué par déformation permanente dudit fil en utilisant une machine existante à commande numérique garantissant la régularité des spires lu Le faible allongement requis ne disjoint que très faiblement les spires du ressort et ne nuit pas à l'aspect esthétique du bijou quel que soit le doigt qui en est habillé. In one embodiment, the spring comprises 100 contiguous turns made of INOX polished wire of suitably selected characteristics and with a diameter of 0.5 mm. This spring is manufactured by permanent deformation of said wire using an existing numerical control machine guaranteeing the regularity of the turns lu The small elongation required disjoins only very slightly the turns of the spring and does not harm the aesthetic appearance of the jewel whatever the finger that is dressed.

Les dessins annexés il lustrent l'invention: - La figure 1 représente une bague réalisée selon le dispositif de l'invention; - La figure 2 représente le ressort avant son raccordement au plateau supérieur 10 de la bague; - La figure 3 représente une des spires du ressort; En référence à ces dessins, le dispositif comprend un plateau 1 destiné à recevoir la décoration souhaitée 2 et comprenant de part et d'autre les réceptacles de forme appropriée 3 et 4 destinés à recevoir respectivement chaque extrémité du ressort 5. Les extrémités du ressort (5) sont introduites à l'intérieur des réceptacles 3 et 4.clans lesquelles elles sont collées ou serties ou retenues par tout autre dispositif mécanique. The accompanying drawings illustrate the invention: - Figure 1 shows a ring made according to the device of the invention; - Figure 2 shows the spring before its connection to the upper plate 10 of the ring; - Figure 3 shows one of the turns of the spring; With reference to these drawings, the device comprises a plate 1 intended to receive the desired decoration 2 and comprising on either side the receptacles of appropriate shape 3 and 4 intended to respectively receive each end of the spring 5. The ends of the spring ( 5) are introduced into the receptacles 3 and 4.clans in which they are glued or crimped or retained by any other mechanical device.

Claims

3 claims

1) Device for producing rings that can be adjusted to the fingers intended to wear it, characterized in that it comprises a plate (1) intended to receive any desired decoration (2), and a deformable ring fixed to said plate (1 ) by connection means secured to said plate (1).

2) Device according to claim 1, characterized in that the deformable ring is constituted by a spring with contiguous turns (5) and in that the connecting means comprise two receptacles (3) and (4) fixed on both sides. other of the plate (1) and provided respectively to receive each of the ends of the spring contiguous turns (5).

(3) Device according to one of the preceding claims, characterized in that the length of the spring (5) is such that when it is fixed to the plate (1), the diameter of the ring thus formed substantially corresponds to that of the smallest finger to wear it.

4) Device according to one of the preceding claims, characterized in that the mechanical characteristics of the spring (5) are such that during the establishment of the ring, said spring lying down only weighs a little pressure distributed around the perimeter of the carrier finger.
