Abstract

The fastener is designed to attach the ends of a chain or cord to the side-pieces of the spectacle frame. The spectacles can, then, hang round the wearer's neck when not being worn. The fastener consists of a supple spiral (1), attached by a connector (2) to each end of the cord or chain and wound round the spectacle frame side-piece. The spiral can be made from a plastics material which can be over-moulded onto the ends of the cord or chain or made in one piece with it. In the event of a sharp involuntary pull on the spectacles the spirals will detach, avoiding damage to the spectacles or injury to the wearer.

Description

Dispositif d'attaches d'une chaînette ou d'un cordon sur des branches de montures de lunettes.Device for attaching a chain or a cord to the branches of spectacle frames.

La présente invention concerne un dispositif d'attaches de divers types de chaînettes ou cordons sur divers types de montures de lunettes, ainsi qu'un ensemble cordon / fixation.The present invention relates to a device for attaching various types of chains or cords to various types of spectacle frames, as well as a cord / attachment assembly.

Il est couramment employé des systèmes qui permettent de s'adapter à différent types de montures de lunettes. It is commonly used systems that allow to adapt to different types of spectacle frames.

D'une part, les moyens d'attaches utilisés restent compliqués dans leur conception, faisant appel au moins à trois pièces en plus du cordon, et à un assemblage réalisable uniquement avec un outillage spécifique.On the one hand, the fastening means used remain complicated in their design, using at least three parts in addition to the cord, and an assembly that can be carried out only with specific tools.

D'autre part un réglage de l'attache sur la branche de lunette est régulièrement nécessaire.On the other hand, an adjustment of the attachment on the telescope branch is regularly necessary.

Les attaches existantes sont principalement réalisées à I' aide de matériaux différents, ce qui implique des fournisseurs différents, et il en résulte des problèmes de stockage. de tri, de manutention, etc..The existing fasteners are mainly made using different materials, which involves different suppliers, and this results in storage problems. sorting, handling, etc.

En outre, les attaches de ces cordons sont dépourvu de tout système de sécurité et en cas d'accroche involontaire et violente du cordon ou des lunettes avec un élément extérieur ii peut en résulter un bris de la monture ou même des blessures corporelles.In addition, the attachments of these cords are devoid of any security system and in the event of unintentional and violent attachment of the cord or the goggles to an external element ii this may result in breakage of the frame or even bodily injury.

La présente invention a pour objet de limiter le nombre de pièces intervenant dans la fabrication.The object of the present invention is to limit the number of parts involved in manufacturing.

L'invention a également pour objet de fournir une attache adaptable à tout types de montures sans aucun réglage.The invention also aims to provide a fastener adaptable to all types of frames without any adjustment.

Un des autre objet de l'invention est de résoudre le problème de sécurité lié au port du cordon autour du cou.Another object of the invention is to solve the security problem linked to the wearing of the cord around the neck.

Selon I' invention, dans un premier cas. I'attache et le cordon sont réalisés à partir d'un matériau souple en une seule pièce.According to the invention, in a first case. The fastener and the cord are made from a flexible material in one piece.

Dans un deuxième cas, ou l'on conserve l'utilisation des cordons actuellement employés pour ce type de produit nous nous trouvons avec un surmoulage des attaches sur les extrémités du cordon, ou avec un clips surmoulé sur le cordon, à relier avec la vrille.In a second case, where we keep the use of cords currently used for this type of product we find ourselves with an overmolding of the fasteners on the ends of the cord, or with a clips overmolded on the cord, to be connected with the twist .

Un cas comme l'autre ont pour effet de rendre le cordon solidaire de l'attache donnant ainsi au produit son entité et son originalité. A case like the other has the effect of making the cord integral with the fastener thus giving the product its entity and its originality.

Description de l'invention,
Une forme de vrille (1) qui vient s'enroulée autour de chaque branches des lunettes sur la partie horizontale entre l'oreille et la charnière.Description of the invention,
A form of tendril (1) which is wound around each branch of the glasses on the horizontal part between the ear and the hinge.

Cette vrille en matériau souple , constitué de plusieurs anneaux ouverts se déforme concentriquement pour s'adapter aux différentes configurations des branches de lunettes, ainsi plus les branches sont épaisses plus le diamètre de la vrille est grand et le nombre d'anneaux réduits.This tendril made of flexible material, consisting of several open rings is deformed concentrically to adapt to the different configurations of the spectacle branches, thus the thicker the branches the greater the diameter of the tendril and the number of rings reduced.

Solidairement à l'une des extrémités de la vrille un dispositif (2) permettant de recevoir la chaînette ou le cordon.In solidarity with one of the ends of the spin, a device (2) for receiving the chain or the cord.

Le dispositif selon l'invention peut être réalisé de divers façons. La principale caractéristique de l'invention étant I' utilisation de la vrille comme attaches sur les branches de lunettes. The device according to the invention can be produced in various ways. The main characteristic of the invention being the use of the spin as fasteners on the branches of glasses.
