Abstract

The frame has a helicoidal spring (3) whose cross bar provides a connection between branches (2) and a frame face (1) where the branches are connected with the frame face. An end piece of the face and another end piece of the branch are maintained and engaged at ends of the spring, where each end piece is provided with a protrusion. The end piece of the branch is incurved towards an inner surface of the branch.

Description

La présente invention est relative à un perfectionnement aux montures de lunettes. The present invention relates to an improvement to eyeglass frames.

Une monture de lunettes comporte deux parties, la face, qui supporte 5 les verres, et les branches qui sont articulées de chaque côté de la face. A spectacle frame has two parts, the face, which supports the lenses, and the branches that are articulated on each side of the face.

Sur ce type d'article, c'est la liaison entre la face et les branches qui pose des problèmes. On this type of article, it is the connection between the face and the branches that poses problems.

10 Dans la majorité des cas, la liaison s'effectue par l'entremise d'une articulation comportant la misé en oeuvre d'une pluralité de pièces, très petites et fragiles. In the majority of cases, the connection is effected by means of a joint comprising the implementation of a plurality of very small and fragile parts.

La rotation de chaque branche n'est autorisée que dans un plan 15 perpendiculaire à l'axe d'articulation, mais si la branche est sollicitée de façon à la faire sortir de ce plan cette manoeuvre intempestive entraîne la destruction de l'articulation. The rotation of each leg is allowed only in a plane perpendicular to the axis of articulation, but if the branch is urged to bring it out of this plane this untimely maneuver leads to the destruction of the joint.

Par la demande de brevet français publiée sous le N° 2906046, on 20 connaît un procédé de fabrication de monture de lunettes en une seule pièce moulée à plat consistant à noyer dans la monture une armature métallique susceptible de subir des déformations permanentes tout en conservant une certaine élasticité. French patent application published under No. 2906046 discloses a process for manufacturing a flat-molded spectacle frame consisting of embedding in the frame a metal frame capable of undergoing permanent deformations while retaining a certain elasticity.

25 Ce procédé permet de simplifier la liaison entre la face et les branches tout en réalisant une liaison robuste et peu fragile, mais l'expérience a montré que ce procédé était relativement coûteux. This method makes it possible to simplify the bond between the face and the branches while achieving a robust and not very brittle bond, but experience has shown that this method is relatively expensive.

La présente invention qui remédie à tous ces inconvénients est remarquable en ce que la liaison de chaque branche à la face s'effectue par l'entremise d'un ressort hélicoïdal enroulé à spires jointives et dans chaque extrémité duquel est engagé et maintenu, respectivement, un embout de la s face et un embout de la branche correspondante. The present invention, which overcomes all these drawbacks, is remarkable in that the connection of each branch to the face is effected by means of a helical spring wound with contiguous turns and in each end of which is engaged and maintained, respectively, a tip of the s face and a tip of the corresponding branch.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement sur lesquels : 10 - la figure 1 est la vue de dessus d'une monture conforme à l'invention, les branches étant représentées dans la position naturelle de repos ; - la figure 2 est une vue analogue à la figure 1, les branches étant représentées en position d'utilisation ; 15 -la figure 3 est une vue selon F de la figure 2 -la figure 4 est une vue analogue à la figure 3, la pièce de liaison entre la face et la branche n'étant pas représentée ; - la figure 5 est la vue de dessus de la branche de la figure 4. The present invention will be better understood from the following description given with reference to the accompanying drawings by way of example only, in which: FIG. 1 is the top view of a frame according to the invention; branches being represented in the natural position of rest; - Figure 2 is a view similar to Figure 1, the branches being shown in the use position; FIG. 3 is a view along F of FIG. 2; FIG. 4 is a view similar to FIG. 3, the connecting piece between the face and the branch not being shown; FIG. 5 is the top view of the branch of FIG. 4.

20 En se reportant aux dessins, on voit que la monture comporte une face 1 à laquelle sont raccordées des branches 2. Referring to the drawings, it can be seen that the frame comprises a face 1 to which branches 2 are connected.

Selon l'invention, le raccordement de chaque branche à la face s'effectue par l'entremise d'un ressort hélicoïdal 3, enroulé à spires jointives. A cet effet, la face 1 et les branches 2 présentent, respectivement des embouts 4 et 5. 25 Chaque embout est engagé dans l'extrémité correspondante du ressort 3, soit librement et sans jeu soit en forçant, soit par une combinaison des deux moyens. According to the invention, the connection of each branch to the face is effected by means of a helical spring 3, wound with contiguous turns. For this purpose, the face 1 and the branches 2 have, respectively, ends 4 and 5. Each end piece is engaged in the corresponding end of the spring 3, either freely and without play or by forcing, or by a combination of the two means. .

s Ainsi, selon un mode de réalisation, l'une des faces de chaque embout présente une protubérance 6 qui se coince entre deux spires adjacentes. Thus, according to one embodiment, one of the faces of each endpiece has a protuberance 6 which is wedged between two adjacent turns.

L'embout 5 de chaque branche, comme cela ressort tout particulièrement de la figure 5, ne s'étend pas dans le plan de la branche, 10 mais est incurvé vers la face interne 2a de la branche. The tip 5 of each branch, as is particularly apparent from Figure 5, does not extend in the plane of the branch, but is curved towards the inner face 2a of the branch.

C'est cette incurvation qui assure, en position de repos, la position des branches selon celle montrée sur la figure 1. It is this bend which ensures, in the rest position, the position of the branches according to that shown in FIG.

15 En position d'utilisation, chaque ressort qui est légèrement bandé tend à reprendre sa forme d'origine, ce qui assure une pression de maintien sur la tête de l'usager. In the position of use, each spring which is slightly bandaged tends to return to its original shape, which ensures a holding pressure on the head of the user.

Ce mode de liaison présente de nombreux avantages parmi lesquels il 20 faut citer sa simplicité de mise en oeuvre, son faible coût de revient et sa robustesse puisque chaque branche peut être sollicitée dans toutes les directions. This mode of connection has many advantages among which we must mention its simplicity of implementation, low cost and robustness since each branch can be requested in all directions.

Ce procédé est compatible avec une interchangeabilité rapide des 25 branches dans un but esthétique par exemple. This method is compatible with rapid interchangeability of branches for aesthetic purposes for example.
