Surbranche interchangeable pour branche de lunettes, son procédé d'obtention et branche composite de lunettes en faisant application.Interchangeable branch for glasses, its method of obtaining and composite branch of glasses by applying.
La présente invention concerne une gaine ou surbranche ornementale interchangeable pour branche de lunettes, plus particulièrement pour branche composite de lunettes, du genre comportant une âme, de préférence métallique, et une gaine d'habillage disposée autour de ladite âme. Elle vise aussi un procédé de fabrication de cette gaine interchangeable et les branches composites de lunettes dotées d'une telle gaine ornementale interchangeable.The present invention relates to an interchangeable ornamental or over-branching branch for eyeglasses, more particularly for a composite branch of spectacles, of the kind comprising a core, preferably a metal, and a covering sheath disposed around said core. It also relates to a method of manufacturing this interchangeable sheath and the composite branches of glasses with such an interchangeable ornamental sheath.
Domaine technique de l'invention.Technical Field of the Invention
L'invention est du domaine des branches pour paire de lunettes de tous types, telles que lunettes de confort, lunettes de vue, lunettes de protection en général, lunettes de protection solaire, etc. Elle a pour objet un élément d'habillage décoratif interchangeable pour les branches de telles paires de lunettes. Plus particulièrement, elle concerne un élément d'habillage pour les branches composites de lunettes, comportant une âme constituée par une lame flexible, métallique ou autre.The invention is in the field of branches for a pair of glasses of all types, such as comfort glasses, eyeglasses, goggles in general, sun protection goggles, etc. It relates to an interchangeable decorative trim element for the branches of such pairs of glasses. More particularly, it relates to a covering element for the composite branches of spectacles, comprising a core constituted by a flexible blade, metal or other.
Etat de la technique.State of the art
Sont connus, des éléments interchangeables pour la décoration d'une branche d'une paire de lunettes. Il est recherché de permettre à l'utilisateur de modifier selon ses désirs l'aspect extérieur de sa paire de lunettes, à partir d'un remplacement de l'élément décoratif en place par un élément ornemental différent choisi parmi une variété d'éléments à sa disposition.Interchangeable elements are known for decorating a branch of a pair of spectacles. It is desired to allow the user to modify as desired the external appearance of his pair of glasses, from a replacement of the decorative element in place by a different ornamental element selected from a variety of elements to his disposition.
Différentes solutions ont été préconisées pour résoudre le problème de la jonction amovible entre la branche de lunettes et l'élément décoratif. Il a notamment été proposé un élément de décoration agencé en barrette amovible rapportée sur la branche de lunettes par des moyens de fixation facilement réversible. Par exemple, les documents GB-2 184 862 et FR-2 836 562 proposent d'agencer l'élément décoratif en barrette rapportée par clipage, latéralement, en juxtaposition le long de la branche. Selon ces documents, sont décrits des éléments décoratifs destinés à être rapportés latéralement sur des branches de lunettes spécialement adaptées à cet effet. Les branches de lunettes munies de ces éléments décoratifs n'ont pas un aspect homogène en raison du fait que lesdits éléments ne recouvrent que la surface externe des branches qui paraissent ainsi constituées d'éléments disparates. En outre, les organes de clipsage qui forment des reliefs sur la face interne des branches peuvent être la cause d'irritation ou de blessures en frottant contre la tempe de l'utilisateur ou d'accrochage des cheveux de celui-ci.Various solutions have been recommended to solve the problem of the removable junction between the eyeglass branch and the decorative element. In particular, it has been proposed a decorative element arranged in removable bar attached to the eyeglass branch by means of easily reversible fixation. For example, documents GB-2 184 862 and FR-2 836 562 propose to arrange the decorative element by insert bar by clipping, laterally, juxtaposition along the branch. According to these documents, there are described decorative elements intended to be laterally reported on glasses branches specially adapted for this purpose. The glasses branches provided with these decorative elements do not have a homogeneous appearance due to the fact that said elements only cover the outer surface of the branches which thus appear to be composed of disparate elements. In addition, the clipping members that form reliefs on the inner side of the branches can be the cause of irritation or injury by rubbing against the temple of the user or the hair of the latter.
Dans le document GB-2 180 664, est décrite une branche composite de lunettes dont la portion temporale est constituée par une gaine tubulaire cylindrique montée de manière interchangeable sur une âme métallique de section circulaire ; cette gaine est maintenue en place par l'extrémité proximale de la pièce d'oreille munie d'un écrou se vissant sur l'extrémité distale filetée de l'âme métallique. Ce dispositif a pour inconvénients : de ne s'appliquer qu'à des lunettes comportant des pièces d'oreilles et des branches de section ronde, de nécessiter la prévision de filetages mâle et femelle aux extrémités de jonction des âmes métalliques et des pièces d'oreilles, de ne pas permettre un remplacement très rapide des gaines interchangeables, une réduction des modifications décoratives possibles (pratiquement réduites à de simples changements de couleur) si l'on considère que la surface cylindrique desdites gaines offre peu de possibilité pour une grande variété de décors.In GB-2 180 664 there is described a composite branch of spectacles whose temporal portion consists of a cylindrical tubular sheath mounted interchangeably on a metal core of circular section; this sheath is held in place by the proximal end of the ear piece provided with a nut screwing onto the threaded distal end of the metal core. This device has the following drawbacks: to apply only to glasses comprising ear pieces and round section branches, to require the provision of male and female threads at the joining ends of the metal cores and pieces of metal. ears, not to allow a very fast replacement of interchangeable sheaths, a reduction of the possible decorative modifications (practically reduced to simple color changes) if one considers that the cylindrical surface of said sheaths offers little possibility for a great variety of decors.
Dans le document GB-2 200473, est décrite une gaine amovible de protection pour branche de lunettes, formée d'un tube de matière souple entourant ladite branche et fixée sur celle-ci par une bague élastique et retournement de l'extrémité ouverte dudit tube autour de ladite bague de fixation. Il s'agit d'une gaine dont la fonction est uniquement de protéger les branches de lunettes et sa mise en place sur lesdites branches ou son retrait ne paraissent pas pouvoir s'opérer facilement et rapidement. Cette gaine qui recouvre à la fois la zone temporale et les pièces d'oreilles de la branche ne peut être réalisée que dans un matériau très souple pour permettre l'enfilage de cette dernière dans ladite gaine. Le document US-5 440 355 décrit également un manchon de protection souple exécuté en matière textile fixé par couture autour de chaque branche des lunettes (portion temporale et pièce d'oreille) et dont la surface intérieure présente un coefficient de friction élevé ; en outre, pour éviter un glissement du manchon de protection sur la branche, l'entrée de ce dernier est munie d'un anneau élastique de serrage. Bien qu'il soit indiqué que ce manchon de protection peut être aisément remplacé, il ne s'agit pas d'une surbranche ornementale interchangeable, mais seulement d'une gaine souple destinée à améliorer le confort du port des lunettes.In document GB-2 200473, there is described a removable protection sleeve for glasses, formed of a tube of flexible material surrounding said branch and fixed thereon by an elastic ring and reversal of the open end of said tube around said fixing ring. It is a sheath whose function is only to protect the branches of glasses and its establishment on said branches or withdrawal do not seem to be able to operate easily and quickly. This sheath which covers both the temporal area and the ear pieces of the branch can be made only in a very flexible material to allow the threading of the latter in said sheath. US-5,440,355 also discloses a flexible protective sleeve made of textile material secured by stitching around each branch of the eyeglasses (temporal portion and ear piece) and whose inner surface has a high coefficient of friction; in addition, to prevent sliding of the protective sleeve on the branch, the input of the latter is provided with an elastic clamping ring. Although it is stated that this protective sleeve can be easily replaced, it is not an interchangeable ornamental overbranch, but only a flexible sheath intended to improve the comfort of wearing glasses.

Selon un premier exemple de mise en œuvre, le moyen s'opposant à tout mouvement de glissement spontané de désassemblage de la gaine sur la lame flexible est constitué par une courbure permanente de la zone temporale de ladite lame flexible et/ou de ladite gaine interchangeable flexible.According to a first example of implementation, the means opposing any spontaneous sliding movement of disassembly of the sheath on the flexible blade is constituted by a permanent curvature of the temporal zone of said flexible blade and / or said interchangeable sheath flexible.
Selon un autre exemple de mise en œuvre de l'invention, la paroi externe de la surbranche présente une longueur supérieure à celle de la paroi interne de ladite surbranche, à l'extrémité proximale de cette dernière, et elle est munie, sur sa face interne, d'un épaulement prenant appui contre la face externe de la portion d'extrémité proximale de la lame flexible dans la position d'assemblage de ladite lame flexible et de ladite surbranche interchangeable, position dans laquelle la portion d'extrémité de la face externe de la surbranche se trouve légèrement fléchie en direction de l'extérieur de sorte à engendrer un effet ressort appliqué audit épaulement qui agit à la manière d'un frein s'opposant à tout glissement non souhaité de ladite surbranche.According to another exemplary embodiment of the invention, the outer wall of the over-spoke has a length greater than that of the inner wall of said over-spoke, at the proximal end of the latter, and is provided on its face. internal, a shoulder bearing against the outer face of the proximal end portion of the flexible blade in the assembly position of said flexible blade and said interchangeable surbranche, position in which the end portion of the face Outer of the ovbranche is slightly bent towards the outside so as to generate a spring effect applied to said shoulder which acts in the manner of a brake opposing any undesired sliding of said overboard.
Selon un mode d'exécution préféré, la portion d'extrémité proximale de cette surbranche est conformée pour s'accrocher automatiquement sur l'extrémité proximale de la lame flexible , en fin de course de coulissement de ladite surbranche sur ladite lame flexible, lors de l'assemblage de celles-ci, de sorte à s'opposer ensuite à tout mouvement de retrait spontané indésirable de la surbranche.According to a preferred embodiment, the proximal end portion of this surbranche is shaped to automatically catch on the proximal end of the flexible blade, at the end of the sliding stroke of said over-tongue on said flexible blade, when the assembly of these, so as to oppose any unwanted spontaneous withdrawal movement of the overbranch.
De manière avantageuse, l'extrémité proximale de la paroi externe de la gaine comporte, dans sa face interne, un dégagement ménagé à l'entrée du couloir et dans lequel vient se loger l'extrémité proximale de la lame flexible, en fin de course de coulissement de ladite gaine sur ladite lame, lors de l'assemblage de celles-ci, et un moyen de retenue à rencontre de son retrait spontané indésirable par coulissement le long de l'âme de la branche.Advantageously, the proximal end of the outer wall of the sheath has, in its inner face, a clearance formed at the entrance of the passageway and in which is housed the proximal end of the flexible blade, at the end of the race. sliding said sheath on said blade, during assembly thereof, and a retaining means against its unwanted spontaneous withdrawal by sliding along the core of the branch.
Selon un mode d'exécution intéressant, le moyen de retenue comprend un épaulement ou saillie ménagé à l'extrémité proximale du dégagement, de sorte à créer une niche permettant le logement de l'extrémité proximale de l'âme métallique et l'accrochage de la gaine. Un avantage important de l'invention est que la surbranche ornementale de forme aplatie peut être mise en place instantanément sur la branche proprement dite, qu'elle peut être retirée tout aussi instantanément par un simple mouvement de coulissement et que la surbranche adhère fortement à l'âme de la branche, dans la position d'assemblage malgré cette possibilité inédite de montage et de démontage instantanés.According to an interesting embodiment, the retaining means comprises a shoulder or projection formed at the proximal end of the recess, so as to create a recess for housing the proximal end of the metal core and the attachment of sheath. An important advantage of the invention is that the flat-shaped ornamental overbranch can be put in place instantly on the branch itself, that it can be removed just as instantly by a simple sliding movement and that the overreach adheres strongly to the blade. soul of the branch, in the assembly position despite this unprecedented possibility of instant assembly and disassembly.
On comprend que l'invention permet de conférer à la branche composite de lunettes un aspect ornemental extérieur particulier, susceptible d'être modifié par l'utilisateur à partir du choix d'un élément semblable parmi un jeu d'éléments d'aspect extérieur spécifique.It will be understood that the invention makes it possible to confer on the composite eyeglass branch a particular external ornamental appearance, which can be modified by the user from the selection of a similar element from a set of elements with a specific external appearance. .
La lame flexible constituant l'âme de la branche et la gaine constituant la surbranche interchangeable sont agencées ou conformées de manière complémentaire pour limiter la course de coulissement de ladite surbranche lors de son positionnement sur ladite âme.The flexible blade constituting the core of the branch and the sheath constituting the interchangeable outer branch are arranged or shaped in complementary manner to limit the sliding stroke of said over-branch when it is positioned on said core.
Selon le mode d'exécution illustré, cet agencement peut être réalisé en adaptant exactement la longueur du couloir longitudinal de la surbranche à la longueur de la lame de la branche. Dans ce cas, la lame flexible constituant l'âme de la branche se trouve mise en butée à l'intérieur du couloir, suivant son sens d'introduction. Cette mise en butée est susceptible d'être obtenue par une prise d'appui de l'extrémité distale de la lame flexible contre l'extrémité fermée du couloir, qui est préférentiellement borgne. Selon un autre mode d'exécution, cet agencement peut être constitué par un épaulement résultant d'une réduction de la largeur du couloir longitudinal, par exemple dans la partie médiane ou approximativement de la surbranche et par un épaulement antagoniste que présente la lame flexible, par exemple dans la partie médiane, ou approximativement, de celle-ci. Le moyen permettant de limiter la course de coulissement de la surbranche lors de son positionnement sur l'âme flexible peut être constituée par l'extrémité proximale de la paroi interne de ladite surbranche qui vient en appui contre l'élément de charnière faisant saillie sur la face interne de l'extrémité proximale de ladite âme flexible. L'invention vise également la réalisation de la surbranche interchangeable par un procédé dit "de shootage", lorsqu'elle est exécutée dans une matière autorisant la mise en oeuvre d'un tel procédé, telle qu'acétate de cellulose ou autre matière plastique présentant les caractéristiques souhaitables.According to the illustrated embodiment, this arrangement can be achieved by adapting exactly the length of the longitudinal path of the overranche to the length of the blade of the branch. In this case, the flexible blade constituting the core of the branch is abutted within the corridor, according to its direction of introduction. This abutment is likely to be obtained by a support of the distal end of the flexible blade against the closed end of the corridor, which is preferably blind. According to another embodiment, this arrangement may consist of a shoulder resulting from a reduction in the width of the longitudinal corridor, for example in the median part or approximately the overrange and by an opposing shoulder that the flexible blade has, for example in the middle part, or approximately, thereof. The means for limiting the sliding stroke of the over-spoke when it is positioned on the flexible core may be constituted by the proximal end of the inner wall of said over-spoke which abuts against the hinge element projecting from the inner face of the proximal end of said flexible core. The invention also aims at the realization of the interchangeable surbranche by a process called "shooting", when it is performed in a material authorizing the implementation of such a process, such as cellulose acetate or other plastic material presenting the desirable characteristics.
Selon ce procédé :According to this method:
- on procède, en premier lieu, au moulage d'une surbranche brute à la forme désirée, au moyen de tout procédé convenable ; - on réalise ensuite un couloir longitudinal à l'intérieur de ladite surbranche brute par introduction, à chaud, à partir de l'extrémité proximale de celle-ci, d'une aiguille de shootage dont la forme est homothétique de celle de l'âme métallique devant être recouverte par la surbranche ; de sorte à déterminer, après son retrait, un espace longitudinal s'étendant entre la paroi interne et la paroi externe de la surbranche ;firstly, the molding of a raw overbranch to the desired shape is carried out by any suitable method; a longitudinal passage is then produced inside said gross overbranche by introducing, when hot, from the proximal end thereof, a shooting needle whose shape is homothetic with that of the core. metal to be covered by the overboard; so as to determine, after removal, a longitudinal space extending between the inner wall and the outer wall of the over-spoke;
- puis on enlève, par exemple par fraisage ou autre procédé de découpage, une portion d'extrémité proximale de ladite paroi interne, de sorte à créer un dégagement à l'entrée du couloir longitudinal ;- Then removes, for example by milling or other cutting method, a proximal end portion of said inner wall, so as to create a clearance at the entrance of the longitudinal corridor;
- on recourbe, enfin, vers l'intérieur et à chaud, l'extrémité de la paroi externe de la surbranche, de sorte à former un épaulement ou saillie délimitant l'extrémité proximale du dégagement.- Finally, the inside of the outer wall of the overbreach is bent inwardly and hot so as to form a shoulder or projection delimiting the proximal end of the recess.
La face externe d'au moins la paroi externe, sinon aussi de la paroi interne, comporte un revêtement décoratif. Un tel revêtement est susceptible d'être rapporté par gravure ou lazer ou autre procédé de gravure, par sérigraphie, par collage d'une feuille, d'une plaquette ou analogue, par surmoulage, vulcanisation ou technique analogue, voire d'être constitué d'un vernis, une laque époxy ou pellicule analogue. Les parois sont aussi susceptibles d'être individuellement ou conjointement formées à partir d'un matériau coloré, opaque ou transparent.The outer face of at least the outer wall, if not also the inner wall, has a decorative coating. Such a coating may be reported by etching or lazer or other etching process, by screen printing, by gluing a sheet, a wafer or the like, by overmolding, vulcanization or similar technique, or even consist of a varnish, an epoxy lacquer or similar film. The walls are also capable of being individually or jointly formed from a colored, opaque or transparent material.

On se reporte auxdits dessins pour décrire un exemple de réalisation intéressant, bien que nullement limitatif, de l'élément d'habillage décoratif interchangeable selon l'invention. Dans la description qui suit, on utilise le néologisme "surbranche" pour désigner la gaine destinée à envelopper, de manière interchangeable, une âme flexible, de sorte à constituer, avec cette dernière, une branche composite de lunettes.Referring to the drawings to describe an example of embodiment interesting, although not limiting, the interchangeable decorative trim element according to the invention. In the description which follows, the "over-branch" neologism is used to designate the sheath intended to interchangeably wrap a flexible core, so as to constitute, with the latter, a composite branch of spectacles.
D'autre part, on utilise, conventionnellement, le mot "proximal" pour désigner la partie des composants de la branche qui se trouve, en position de montage, la plus proche de la monture de la paire de lunettes, et le mot "distal", pour identifier la partie desdits composants qui se trouve la plus éloignée de ladite monture. De même, on utilise, conventionnellement, l'expression "paroi externe" pour désigner la paroi de la gaine qui est orientée vers l'extérieur et qui est principalement visible lorsque l'utilisateur est porteur des lunettes, et l'expression "paroi interne" pour désigner la paroi de ladite gaine qui est orientée vers sa tempe.On the other hand, the word "proximal" is conventionally used to designate the part of the components of the branch which, in the mounting position, is closest to the frame of the pair of spectacles, and the word "distal" ", to identify the part of said components which is furthest from said mount. Similarly, the term "external wall" is conventionally used to designate the wall of the sheath which is oriented towards the outside and which is mainly visible when the wearer is wearing glasses, and the expression "inner wall". "to designate the wall of said sheath which is oriented towards his temple.
Enfin, dans l'exposé qui suit, le mot "flexible" signifie : qui se laisse courber sous un effort ou une pression manuelle et qui tend à reprendre sa forme initiale lorsque cet effort ou pression n'est plus appliqué(e).Finally, in the following description, the word "flexible" means: which is allowed to bend under manual effort or pressure and which tends to return to its original shape when this effort or pressure is no longer applied.
Selon l'invention, la branche composite de lunettes 1 comprend une lame flexible aplatie 2, constituant l'âme de la branche et une surbranche ornementale interchangeable 5 constituée par une gaine flexible semi-rigide de forme allongée et aplatie, comportant une paroi externe 11 et une paroi interne 10 délimitant un couloir longitudinal 6 de section oblongue, dans lequel est engagée ladite lame flexible, jusqu'à proximité de son extrémité articulée à la monture de lunettes, ladite branche aplatie et/ou ladite gaine étant agencée(s), de manière à permettre leur assemblage manuel amovible par coulissement, sous une faible force manuelle de poussée, et s'opposant ensuite à tout mouvement non souhaité de retrait de ladite gaine.According to the invention, the composite eyeglass branch 1 comprises a flattened flexible blade 2 constituting the core of the branch and an interchangeable ornamental overbrace 5 constituted by a semi-rigid flexible sheath of elongated and flattened shape, comprising an outer wall 11 and an inner wall 10 delimiting a longitudinal passage 6 of oblong section, in which is engaged said flexible blade, to near its end articulated to the spectacle frame, said flattened branch and / or said sheath being arranged (s), so as to allow their manual assembly removable by sliding, under a low manual pushing force, and then opposing any unwanted movement of removal of said sheath.
Selon un premier exemple de mise en œuvre, le moyen s'opposant à tout mouvement de glissement spontané de désassemblage de la gaine sur la lame flexible est constitué par une courbure permanente de la zone ou région temporale 2a de ladite lame flexible 2, comme illustré aux figures 13 à 15, et/ou de ladite gaine interchangeable flexible.According to a first example of implementation, the means preventing any spontaneous sliding movement of disassembly of the sheath on the flexible blade is constituted by a permanent curvature of the zone or temporal region. 2a of said flexible blade 2, as shown in Figures 13 to 15, and / or of said flexible interchangeable sheath.
Selon un autre exemple de mise en œuvre de l'invention, la paroi externe 11 de la surbranche 5 présente une longueur supérieure à celle de la paroi interne 10 de ladite surbranche, à l'extrémité proximale de cette dernière, et elle est munie, sur sa face interne, d'un épaulement 16 prenant appui contre la face externe de la portion d'extrémité proximale de la lame flexible 2 dans la position d'assemblage de ladite lame flexible et de la dite surbranche interchangeable, position dans laquelle la portion d'extrémité 11a de la paroi externe 11 de la surbranche 5 se trouve légèrement fléchie en direction de l'extérieur (figure 17), de sorte à engendrer un effet ressort appliqué audit épaulement qui agit à la manière d'un frein s'opposant à tout glissement non souhaité de ladite surbranche.According to another exemplary embodiment of the invention, the outer wall 11 of the over-spoke 5 has a length greater than that of the inner wall 10 of said over-hook, at the proximal end thereof, and is provided with, on its inner face, a shoulder 16 bearing against the outer face of the proximal end portion of the flexible blade 2 in the assembly position of said flexible blade and said interchangeable surbranche, position in which the portion end 11a of the outer wall 11 of the overrode 5 is slightly bent towards the outside (Figure 17), so as to generate a spring effect applied to said shoulder which acts in the manner of an opposing brake any unwanted sliding of said overbranch.
Selon un mode d'exécution préféré, la portion d'extrémité proximale de cette surbranche est conformée pour s'accrocher automatiquement, de préférence par clipsage, sur l'extrémité proximale de la lame flexible, en fin de course de coulissement de ladite surbranche sur ladite lame flexible, lors de l'assemblage de celles-ci, de sorte à s'opposer ensuite à tout mouvement de retrait spontané indésirable de la surbranche.According to a preferred embodiment, the proximal end portion of this surbranche is shaped to catch automatically, preferably by clipping, on the proximal end of the flexible blade, at the end of the sliding stroke of said over-spoke on said flexible blade, during assembly thereof, so as to then oppose any unwanted spontaneous withdrawal movement of the over-board.
Sur la figure 1 , est montrée une âme de lunettes destinée à être associée à une surbranche interchangeable, pour constituer une branche composite de lunettes. Cette âme est principalement constituée d'une lame flexible 2, de préférence métallique, qui est équipée, à son extrémité proximale, d'un élément 3 de charnière d'articulation à la monture des lunettes (non représentée) exécutée de façon connue en soi. La lame flexible est de préférence effilée vers son extrémité distale 4. Elle peut, par exemple, présenter une épaisseur de l'ordre de ± 0,26 mm, une largeur de ± 6 mm à proximité de son extrémité d'articulation et une largeur de ± 2,5 mm à proximité de son extrémité libre. La longueur de cette lame flexible varie en fonction de la morphologie de la tête des individus ; elle est dimensionnée pour recouvrir la zone temporale et reposer sur l'oreille par l'intermédiaire de son extrémité distale. Elle ne comporte pas de pièces d'oreilles.In Figure 1, there is shown a spectacle core intended to be associated with an interchangeable surbranche, to form a composite branch of glasses. This core consists mainly of a flexible blade 2, preferably metal, which is equipped, at its proximal end, with a hinge hinge member 3 to the spectacle frame (not shown) executed in a manner known per se. . The flexible blade is preferably tapered towards its distal end 4. It may, for example, have a thickness of the order of ± 0.26 mm, a width of ± 6 mm near its hinge end and a width ± 2.5 mm near its free end. The length of this flexible blade varies according to the morphology of the head of the individuals; she is sized to cover the temporal area and rest on the ear via its distal end. It does not have ear pieces.
Sur les figures 2 à 6, la surbranche est agencée en gaine 5 de forme allongée et aplatie, destinée à envelopper l'âme flexible 2. On note qu'il est préféré que la surbranche 5 enveloppe l'âme 2 dans sa quasi-totalité, mais que le recouvrement de l'âme 2 par la gaine 5 est susceptible d'être au moins partiel sans pour autant déroger aux règles de la présente invention. La surbranche 5 est rapportée sur l'âme 2 par coulissement glissant, pour permettre sa mise en place et son retrait aisés par l'utilisateur. A cet effet, la surbranche 5 comporte un couloir interne longitudinal 6 destiné à recevoir l'âme 2. Ce couloir 6 est notamment débouchant à l'extrémité proximale 7 de la surbranche 5 pour l'introduction de l'âme 2 par l'extrémité distale libre 4 de cette dernière, de sorte à réaliser l'assemblage de l'âme 2 et de la surbranche 5. En considérant l'application avantageuse de l'invention à la réalisation de branches composites 1 de lunettes comportant une âme constituée par une lame flexible aplatie 2, enveloppée d'une surbranche interchangeable 5, le couloir 6 présente une section oblongue sensiblement rectangulaire délimitée par une paroi interne 10 et par une paroi externe 11 , délimitant ledit couloir 6 et permettant le coulissement de ladite lame 2 dans ce dernier, sans jeu latéral notable. Cette conformation de la branche et de l'habillage ornemental empêche toute rotation de ce dernier autour de ladite branche.In FIGS. 2 to 6, the overrange is arranged in sheath 5 of elongated and flattened shape, intended to envelop the flexible core 2. It is noted that it is preferred that the overwrap 5 envelops the core 2 in its quasi-totality. but that the recovery of the core 2 by the sheath 5 is likely to be at least partial without derogating from the rules of the present invention. The overrode 5 is attached to the core 2 by sliding sliding, to allow its establishment and easy removal by the user. To this end, the overrode 5 comprises a longitudinal internal passage 6 intended to receive the core 2. This passage 6 is in particular opening at the proximal end 7 of the over-branch 5 for the insertion of the core 2 by the end free distal 4 of the latter, so as to achieve the assembly of the core 2 and the surgeon 5. Considering the advantageous application of the invention to the realization of composite branches 1 of glasses having a core constituted by a flattened flexible blade 2, wrapped with an interchangeable surbranche 5, the passage 6 has a substantially rectangular oblong section delimited by an inner wall 10 and by an outer wall 11, delimiting said passage 6 and allowing the sliding of said blade 2 in the latter , without significant lateral play. This conformation of the branch and the ornamental cladding prevents any rotation of the latter around said branch.
La lame flexible 2 constituant l'âme de la branche et la gaine 5 constituant la surbranche interchangeable sont agencées de manière complémentaire pour limiter la course de coulissement de ladite surbranche lors de son positionnement sur ladite lame flexible.The flexible blade 2 constituting the core of the branch and the sheath 5 constituting the interchangeable sub-branch are arranged in a complementary manner to limit the sliding stroke of said over-branch when it is positioned on said flexible blade.
Selon l'exemple de réalisation illustré, le couloir 6 est borgne à son extrémité distale pour ménager un organe de butée distale 12 limitant la course de l'âme 2 à l'intérieur de la surbranche 5. Alternativement ou complémentairement, le couloir 6 peut comporter un épaulement médian 8 susceptible de former lui aussi un organe de butée de fin de course de la gaine 5 sur l'âme 2, cet épaulement médian 8 coopérant avec un épaulement antagoniste 9 que comporte ladite âme 2. La butée permettant de limiter la course de coulissement de la surbranche 5 lors de son installation sur l'âme flexible 2 peut aussi être constituée par l'élément de charnière 3 dont est munie la face interne de la portion d'extrémité proximale de ladite âme flexible 2 et contre laquelle vient en appui l'extrémité proximale 20 de la paroi interne 10 de ladite surbranche, en fin de course de positionnement.According to the exemplary embodiment illustrated, the passage 6 is blind at its distal end to provide a distal abutment member 12 limiting the stroke of the core 2 inside the override 5. Alternatively or additionally, the corridor 6 can have a median shoulder 8 may also form a limit stop member of the sheath 5 on the core 2, the medial shoulder 8 cooperating with an opposing shoulder 9 that comprises said core 2. The stop to limit the sliding stroke of the overwire 5 during its installation on the flexible core 2 may also be constituted by the hinge element 3 which is provided with the inner face of the proximal end portion of said flexible core 2 and against which abuts the proximal end 20 of the inner wall 10 of said surbranche, at the end of the positioning stroke.
La surbranche 5 peut être avantageusement réalisée en matière plastique rigide ou semi-rigide présentant une certaine flexibilité, par tout procédé convenable. Elle est, par exemple, réalisée en acétate de cellulose ou toute matière présentant des qualités comparables et, notamment, une matière déformable ou modelable à chaud.The overrode 5 may advantageously be made of rigid or semi-rigid plastic material having a certain flexibility, by any suitable method. It is, for example, made of cellulose acetate or any material having comparable qualities and, in particular, a deformable or hot-moldable material.
Un marquage à caractère ornemental peut être réalisé sur l'une quelconque au moins des faces visibles de la surbranche 5, et plus particulièrement sur celle de la paroi externe 11. Un tel marquage peut être réalisé par tout procédé convenable, par exemple par gravure au lazer ou autre procédé de gravure, par sérigraphie, par revêtement d'une laque époxy, d'un vernis ou analogue, et prendre la forme d'un dessin ou d'un message publicitaire, tel que slogan, marque ou logo.Ornamental marking may be carried out on at least one of the visible faces of the overrode 5, and more particularly on that of the outer wall 11. Such marking may be carried out by any suitable method, for example by etching. lazer or other etching process, by screen printing, by coating an epoxy lacquer, a varnish or the like, and take the form of a drawing or an advertising message, such as slogan, mark or logo.
Sur sa face interne, la gaine 5 comporte, dans sa portion d'extrémité proximale 7, un dégagement 15, par exemple d'une longueur de l'ordre de 5 à 20 mm et dont l'extrémité proximale est munie d'une organe de butée qui peut être constitué par un épaulement 16. Le dégagement 15 est destiné à faciliter l'introduction à l'intérieur du couloir 6 de l'âme 2, notamment en orientant cette dernière transversalement au plan général des parois 10,11 , puis en faisant glisser l'âme 12 à l'intérieur du couloir 6. L'introduction et le retrait par coulissement sont autorisés, grâce à la présence du dégagement 15 et à la flexibilité de la lame flexible 2 et de la gaine 5.On its inner face, the sheath 5 comprises, in its proximal end portion 7, a clearance 15, for example of a length of the order of 5 to 20 mm and whose proximal end is provided with an organ abutment which may be constituted by a shoulder 16. The clearance 15 is intended to facilitate the introduction into the interior of the corridor 6 of the core 2, in particular by orienting the latter transversely to the general plane of the walls 10, 11, and then by sliding the core 12 inside the corridor 6. Sliding introduction and retraction are allowed, thanks to the presence of the clearance 15 and the flexibility of the flexible blade 2 and the sheath 5.
L'âme 2 étant complètement introduite à l'intérieur du couloir 6, la portion proximale de celle-ci est automatiquement plaquée et clipsée, en fin de course, grâce à l'élasticité de la portion proximale 11a de la paroi externe 11 de la gaine 5, contre le fond du dégagement 15. L'extrémité proximale 17 de l'âme 2 prend appui contre la butée proximale 16 pour interdire tout mouvement de retrait spontané non souhaité de la surbranche 5 sur l'âme 2 de la branche 1.The core 2 being completely inserted inside the corridor 6, the proximal portion thereof is automatically plated and clipped, at the end of the stroke, thanks to the elasticity of the proximal portion 11a of the outer wall 11 of the sheath 5, against the bottom of the clearance 15. The proximal end 17 of the core 2 bears against the proximal stop 16 to prevent any withdrawal movement unwanted spontaneous response of the overrode 5 on the core 2 of the branch 1.
On comprend que lorsqu'un possesseur de lunettes souhaite changer l'aspect de celles-ci en modifiant l'apparence de leurs branches 1 , il suffit d'écarter légèrement les extrémités proximales de l'âme 2 et de la surbranche 5 pour dégager l'extrémité proximale de ladite âme du dégagement ou niche 15 de ladite surbranche, et retirer cette dernière par simple glissement, et de la remplacer par une nouvelle surbranche choisie parmi un jeu de surbranches interchangeables analogues diversement enjolivées, la mise en place de la nouvelle surbranche s'opérant quasi instantanément par coulissement sur l'âme 2 et clipsage en fin de course.It is understood that when an eyeglass owner wishes to change the appearance thereof by changing the appearance of their branches 1, it is sufficient to spread slightly the proximal ends of the core 2 and the overrode 5 to clear the the proximal end of said release core or niche 15 of said surbranche, and remove the latter by simply sliding, and replace it with a new surbranche selected from a set of alternately interchangeable sur-branches variously embellished, the establishment of the new surbranche operating almost instantaneously by sliding on the core 2 and clipping at the end of the race.
Durant le changement, l'âme 2 de la branche reste rattachée à la monture de lunettes par l'articulation à charnière habituelle.During the change, the soul 2 of the branch remains attached to the eyeglass frame by the usual hinge joint.
L'invention concerne également le procédé de fabrication de la surbranche 5 selon lequel :The invention also relates to the method of manufacturing the over-board 5 according to which:
- on procède, en premier lieu, au moulage d'une surbranche brute 5a à la forme désirée (figure 7), au moyen de tout procédé convenable en fonction de la matière plastique utilisée, acétate de cellulose, par exemple ;firstly, the molding of a gross overwire 5a is carried out in the desired form (FIG. 7), by means of any suitable method depending on the plastic used, cellulose acetate, for example;
- on réalise ensuite (figures 8 et 9) un couloir longitudinal 6 à l'intérieur de la surbranche 5a obtenue, par introduction, à chaud, à partir de l'extrémité proximale de ladite surbranche, d'une aiguille de shootage 18 dont la forme est homothétique de celle de l'âme métallique appelée à être enveloppée par la surbranche, de sorte à déterminer, après le retrait de ladite aiguille de shootage (figure 10), un espace ou couloir longitudinal s'étendant entre la paroi interne et la paroi externe de la surbranche 5b et dont la configuration correspond à une contreforme de ladite âme métallique ; - puis on enlève (figure 11), par exemple par fraisage ou autre procédé de découpage, une portion d'extrémité proximale 19 de la paroi interne 10 de la surbranche 5c de sorte à créer un dégagement 15 à l'entrée du couloir longitudinal ; - on chauffe, enfin, l'extrémité proximale ainsi agencée et on recourbe vers l'intérieur l'extrémité de la paroi externe 11 de la surbranche (figure 12), de sorte à former un épaulement ou saillie 16 délimitant l'extrémité proximale du dégagement 15 et à créer une niche pour la réception et le clipsage de l'extrémité proximale de l'âme métallique de la branche.a longitudinal passage 6 is then made (FIGS. 8 and 9) inside the overrode 5a obtained, by introducing, hot, from the proximal end of said over-branch, a shooting needle 18 whose shape is homothetic to that of the metal core to be wrapped by the overrange, so as to determine, after removal of said shooting needle (Figure 10), a longitudinal space or corridor extending between the inner wall and the outer wall of the outer plate 5b and whose configuration corresponds to a counterfoil of said metal core; - Then removes (Figure 11), for example by milling or other cutting method, a proximal end portion 19 of the inner wall 10 of the over-spoke 5c so as to create a clearance 15 at the entrance of the longitudinal corridor; finally, the proximal end thus arranged is heated, and the end of the outer wall 11 of the over-hook (FIG. 12) is bent inwardly so as to form a shoulder or projection 16 delimiting the proximal end of the clearance 15 and to create a niche for receiving and clipping the proximal end of the metal core of the branch.
L'invention concerne également les surbranches interchangeables 5 comportant les caractéristiques exposées ci-dessus et destinées à la réalisation de branches composites de lunettes à surbranches interchangeables précédemment décrites.The invention also relates to interchangeable spacers 5 having the features set out above and intended for producing composite branches of interchangeable interchangeable goggles previously described.
Elle vise aussi les lunettes munies de branches composites à surbranches interchangeables réalisées selon l'exposé qui précède. It also relates to glasses with interchangeable composite branches to interchangeable branches made according to the above discussion.
