Abstract

The invention concerns a method and devices for simple repair of spectacles equipped with elastic temple hinges. The method consists in locking in withdrawn position the sliding stem (4) of the elastic hinge, securing to the sliding stem previously withdrawn a locking device (5). Said device being urged to stop on a surface of the temple prevents the stem from penetrating its housing, and cancels the return force of the spring, thus enabling the screw of the hinge (1) to be easily set in position or removed.

Description

SYSTEME POUR LE MONTAGE ET LA REPARATION DES LUNETTES MONTES DE CHARNIERES DE BRANCHES ELASTIQUESSYSTEM FOR MOUNTING AND REPAIRING GLASSES MADE OF ELASTIC BRANCH HINGES
La présente invention décrit des systèmes facilitant la réparation, le montage et le démontage des branches sur des lunettes munies de charnières élastiques.The present invention describes systems facilitating the repair, assembly and disassembly of branches on spectacles with elastic hinges.
Une paire de lunettes représentée figure 1, comporte à l'avant deux lentilles ou verres correcteurs ou non, chacun venant se placer devant chaque oeil de la personne qui les porte. Les verres sont rendus solidaires de diverses manières comme par exemple par une monture (2) dans laquelle ils sont intégrés, ou par l'ajout d'éléments de liaison fixés sur les verres. Du coté externe de chaque oeil, soit directement sur les verres soit sur la monture qui les rend solidaires, se trouve le plus souvent fixée la partie fixe d'une charnière (7) sur laquelle vient s'articuler une branche (3) . Les branches (3) ouvertes se reposent sur les oreilles du porteur, stabilisant ainsi les verres devant les yeux.A pair of glasses shown in Figure 1, has in front two lenses or corrective glasses or not, each coming to stand before each eye of the person who wears them. The glasses are secured in various ways such as for example by a frame (2) in which they are integrated, or by the addition of connecting elements attached to the glasses. On the outer side of each eye, either directly on the glasses or on the frame that makes them integral, is most often fixed the fixed part of a hinge (7) on which is articulated a branch (3). The branches (3) open rest on the wearer's ears, thus stabilizing the glasses in front of the eyes.
La charnière entre la branche et la partie avant des lunettes est le plus souvent constituée de la manière suivante :The hinge between the branch and the front part of the glasses is most often constituted as follows:
la branche comporte à son extrémité coté verre une tige (4) coulissant dans son logement (3b) solidaire de la branche, et dont le mouvement est contraint par un ressort de rappel qui la tire vers l'intérieur de son logement (3b). La tige comporte à son extrémité un trou, à travers lequel elle se fixe sur la partie fixe de la charnière (7) . La monture ou le verre lui même est solidaire de la partie fixe de la charnière (7) constituée principalement d'une pièce en forme de λU' dont les deux faces parallèles, sont percées. Entre ces deux faces vient se loger le trou de la tige coulissante (4) Un dispositif de fixation de branche (1) (vis, goupille, rivet ou autre système analogue) passe à travers les 3 trous, de la partie fixe de la charnière (7) et de la tige coulissante (4) , rendant ainsi l'ensemble monture, verres, branches, solidaire, mais avec une liaison souple.the branch has at its end glass side a rod (4) sliding in its housing (3b) integral with the branch, and whose movement is constrained by a return spring which pulls inwardly of its housing (3b). The rod has at its end a hole, through which it is fixed on the fixed part of the hinge (7). The mount or the glass itself is integral with the fixed part of the hinge (7) consisting mainly of a piece in the form of λ U 'whose two parallel faces are pierced. Between these two faces is housed the hole of the sliding rod (4) A branch fixing device (1) (screw, pin, rivet or other similar system) passes through the 3 holes, the fixed part of the hinge (7) and the sliding rod (4), thus making it set frame, glasses, branches, solidary, but with a flexible connection.
L'ensemble permet d'articuler les branches, et ainsi de les replier contre les verres pour pouvoir ranger les lunettes plus aisément. Le ressort de rappel de la tige coulissante (4) permet de maintenir les branches soit repliées soit ouvertes, et rend la charnière élastique.The set allows you to articulate the branches, and so to fold against the glasses to be able to store the glasses more easily. The return spring of the sliding rod (4) keeps the branches folded or open, and makes the hinge elastic.
L'art antérieure connaît de multiples réalisations de la charnière élastique, par exemple avec un ressort en traction, comme dans le brevet FR2772148A1, ou encore avec un ou plusieurs ressorts en compression comme dans le brevet FR2772148A1, ou encore avec un dispositif permettant de régler la tension du ressort comme dans le brevet US6585371B1, ou enfin avec un dispositif permettant de limiter le travail du ressort, comme dans le brevet FR2767390A1.The prior art knows multiple embodiments of the elastic hinge, for example with a tensile spring, as in the patent FR2772148A1, or with one or more springs in compression as in the patent FR2772148A1, or with a device for adjusting the spring tension as in US6585371B1, or finally with a device for limiting the work of the spring, as in the patent FR2767390A1.
L'avantage commun à tous ces dispositifs rendant la charnière élastique est d'optimiser et de rendre plus pratique l'usage des lunettes qui les comportent, mais pourtant tous ces dispositifs ont un défaut commun : celui de rendre très fastidieuses les opérations de réparation, de démontage ou de montage des branches, ainsi que de remplacement du système de fixation de branche car ces opérations nécessitent la mise en alignement du trou de la tige coulissante (4) avec les 2 trous de la partie fixe de la charnière, avant de pouvoir passer le dispositif de fixation à travers ces 3 trous préalablement alignés. Or le ressort de rappel de la tige coulissante (4) empêche l'alignement, car il tire la tige (4) en arrière, vers l'intérieur de son logement (3b). Cela est clairement montré sur la figure 2.The common advantage of all these devices making the elastic hinge is to optimize and make more convenient the use of glasses that include them, but all these devices have a common defect: that of making very tedious repair operations, dismantling or mounting branches, and replacing the branch attachment system because these operations require the alignment of the hole of the sliding rod (4) with the 2 holes of the fixed part of the hinge, before being able to pass the fixing device through these 3 pre-aligned holes. But the return spring of the sliding rod (4) prevents alignment, because it pulls the rod (4) backwards, towards the inside of its housing (3b). This is clearly shown in Figure 2.
Le technicien effectuant la réparation ou le montage de la branche n'a d'autre choix que de passer un objet pointu suffisamment mince dans l'un des deux trous de la fixation, d'aller chercher et de tirer avec la pointe de cet objet la tige coulissante (4) vers l'extérieur de son logement (3b) pour placer tant bien que mal son trou en alignement avec les trous de la partie fixe de la charnière (7) , puis ensuite tout en maintenant l'alignement, de passer le système de fixation d'abord dans l'autre trou, puis ensuite à travers la tige coulissante (4) , puis enfin dans le trou par lequel était passée la pointe. L'épaisseur de la tige coulissante (4) n'étant pas importante, contrairement à la force du ressort de rappel, cette opération n'est pas aisée, quoi que très fréquente et fait donc perdre beaucoup de temps aux opticiens.The technician performing the repair or assembly of the branch has no choice but to pass a sufficiently thin pointed object in one of the two holes of the binding, to pick and shoot with the tip of this object. the sliding rod (4) towards the outside of its housing (3b) so as to position its hole as well as possible in alignment with the holes in the fixed part of the hinge (7), and then while maintaining the alignment, pass the fastening system first into the other hole, then through the sliding rod (4), and finally into the hole through which the tip was passed. The thickness of the sliding rod (4) is not important, unlike the force of the return spring, this operation is not easy, although very common and therefore wasting a lot of time opticians.
Nous ne connaissons pas d'outils sur le marché, destinés aux techniciens de l'optique et résolvant le problème du montage des branches de lunettes équipées de charnières élastiques.We do not know any tools on the market, intended for the optical technicians and solving the problem of the assembly of the glasses branches equipped with elastic hinges.
Le brevet américain numéro US006793208B1 propose une solution à ce problème prenant l'aspect d'une pince chirurgicale, munie à son extrémité de deux dents représentées « FIG.4 de US006793208B1 », l'une en forme de pointe « (28) de US006793208B1 », et l'autre en forme de lame « (29) de US006793208B1 » qui permettent de maintenir tirée à l'extérieur de son logement (3b) la tige coulissante (4) préalablement tirée, à l'aide d'une pointe . Ce dispositif présente de multiples inconvénients, dont :US Patent No. US006793208B1 proposes a solution to this problem taking the appearance of a surgical clip, provided at its end with two teeth shown "FIG.4 of US006793208B1", a peak-shaped "(28) of US006793208B1 "And the other blade-shaped" (29) US006793208B1 "that keep pulled out of its housing (3b) the sliding rod (4) previously drawn, using a tip. This device has many disadvantages, including:
La pression devant être exercée pour maintenir la tige coulissante (4) sortie étant importante en raison de la puissance des ressorts de rappel utilisés dans les charnières de lunettes, on risque d'endommager, en la marquant, une branche pas très dure, polie ou peinte, souvent en plastique ou en métal, parfois en bois et donc fragile.The pressure to be exerted to maintain the sliding rod (4) output is important because of the power of the return springs used in the hinges of glasses, there is a risk of damaging, marking it, a not very hard, polished or painted, often plastic or metal, sometimes wood and therefore fragile.
La mise en œuvre de l'outil nécessite une grande adresse dans sa mise en œuvre, puisque son opérateur doit avec sa première main maintenir la branche ouverte en extension « (FIG.9) de US006793208B1 », et avec l'autre main, située nécessairement à une vingtaine de centimètres de la zone de travail, placer la pointe ou la lame de l'outil très précisément sur la tige coulissante (4) « (FIG.11 et FIG.12) de US006793208B1 », en évitant que l'encombrement de l'outil n'empêche l'insertion de la tige coulissante (4) à sa place, et enfin il doit serrer la pince pour bloquer la tige coulissante (4) sortie.The implementation of the tool requires a great address in its implementation, since its operator must with his first hand hold the open branch in extension "(FIG.9) of US006793208B1", and with the other hand, located necessarily at about twenty centimeters from the working area, place the tip or the blade of the tool very precisely on the sliding rod (4) "(FIG.11 and FIG.12) of US006793208B1", avoiding that the size of the tool prevents the insertion of the sliding rod (4) in its place, and finally it must tighten the clamp to block the sliding rod (4) output.
La disposition de la pointe ou de la lame sur la tige coulissante (4) se fait nécessairement sur la tranche de cette dernière et non sur le plat . La pression exercée sur elle pour la bloquer pouvant par conséquent la marquer ou la déformer, et même en altérer le coulissement .The arrangement of the tip or the blade on the sliding rod (4) is necessarily on the edge of the latter and not on the flat. The pressure exerted on it to block it can consequently mark or distort it, and even alter the sliding.
La présente invention entend remédier aux inconvénients de l'art antérieur en proposant diverses variantes de solutions pour optimiser la réparation, le montage, le démontage de lunettes comportant des charnières élastiques . La mise en œuvre de ces solutions est extrêmement facile, ne nécessite pas de dextérité particulière, et réduit au minimum le risque d'abîmer ou de marquer, la branche (3), ou la tige coulissante (4) .The present invention intends to overcome the drawbacks of the prior art by proposing various variants of solutions to optimize the repair, assembly, disassembly of spectacles having elastic hinges. The implementation of these solutions is extremely easy, does not require special dexterity, and minimizes the risk of damaging or marking, the branch (3), or the sliding rod (4).
Cette invention pourra être utilisée pour le montage de toutes les branches élastiques et plus particulièrement celles pour lesquelles la tige coulissante (4) en position rentrée dans son fourreau, est en retrait par rapport au trou de passage de vis de la charnière (7) de la monture (2) lorsque la branche est démontée.This invention can be used for mounting all the elastic branches and more particularly those for which the sliding rod (4) in the retracted position in its sleeve, is set back relative to the screw hole of the hinge (7) of the mount (2) when the branch is disassembled.
La spécificité de l'invention tient dans les principes suivants :The specificity of the invention lies in the following principles:
A. Le procédé visant à bloquer la tige coulissanteA. The process for locking the sliding rod
(4) d'une charnière de lunettes élastique, en position sortie de son logement (3b) , consiste à rendre solidaire de la tige coulissante (4) préalablement sortie de son logement (3b) un dispositif de blocage. Ce dispositif bloque la tige coulissante (4), et l'empêche rentrer dans son logement (3b), sous l'effet de la force de rappel .(4) a hinge of elastic goggles, in the extended position of its housing (3b), consists in making integral with the sliding rod (4) previously output from its housing (3b) a locking device. This device blocks the sliding rod (4), and prevents it from entering its housing (3b), under the effect of the restoring force.
B. Un dispositif de blocage pour la mise en œuvre du procédé de blocage A peut se fixer sur la tige coulissante (4) grâce à une mâchoire articulée comportant deux lames parallèles qui pincent la tige coulissante (4) , et qui peuvent être planes ou comporter une ou plusieurs dents et éventuellement être recouvertes d'un matériau en améliorant l'adhérence sur la tige coulissante (4) . C. L'articulation de la mâchoire du dispositif de blocage décrit en B. peut être réalisée en utilisant la flexibilité de la matière dans laquelle il est réalisé, et en particulier celle dont est constituée sa partie opposée à la mâchoire (5b) .B. A locking device for implementing the locking method A can be fixed on the sliding rod (4) by means of an articulated jaw comprising two parallel blades which grip the sliding rod (4), and which can be flat or have one or more teeth and possibly be covered with a material by improving the adhesion on the sliding rod (4). C. The articulation of the jaw of the locking device described in B. can be achieved by using the flexibility of the material in which it is made, and in particular that of which is constituted its opposite portion to the jaw (5b).
D. Suivant différentes réalisations, le dispositif de blocage décrit en B . ou en C. pourra comporter un ressort soit pour bloquer les mâchoires sur la tige coulissante (4) , soit pour les ouvrir. Ledit ressort peut éventuellement être intégré à l'articulation de la mâchoire dans la réalisation du dispositif de blocage ou être disposé à un quelconque autre endroit lui permettant suivant les réalisations soit de resserrer les mâchoires, soit de les écarter.D. According to different embodiments, the locking device described in B. or in C. may comprise a spring either to lock the jaws on the sliding rod (4), or to open them. Said spring may optionally be integrated in the articulation of the jaw in the embodiment of the locking device or be arranged at any other location allowing it according to the embodiments is to tighten the jaws, or to separate them.
E. Le dispositif de blocage suivant l'un quelconque des principes B a D pourra comporter un dispositif quelconque visant à en commander par action de son opérateur l'écartement et le resserrement les mâchoires .E. The locking device according to any one of principles B to D may include any device for controlling by action of its operator spacing and tightening the jaws.
F. Dans l'application du principe E le dispositif utilisé pour commander l'écartement et le resserrement les mâchoires blocage pourra être une vis avec une molette.F. In the application of the principle E the device used to control the spacing and tightening the locking jaws may be a screw with a knob.
G. On pourra avantageusement simplifier le blocage selon le procédé A de la tige coulissante (4) en position sortie de son logement (3b) et le rendre possible sans outil dispositif de blocage compliqué. A cet effet, la tige coulissante sera modifiée par ajout sur celle-ci d'une forme concave ou convexe, ou d'un trou (15) placé sur celle-ci, de sorte à permettre son blocage en position sortie hors de son logement, par insertion d'un objet dans/sur/contre ladite forme, qui viendra bloquer la tige sortie contre la branche pour en empêcher le retour et annuler la force de rappel du ressort.G. It is advantageous to simplify the locking according to method A of the sliding rod (4) in the extended position of its housing (3b) and make it possible without a complicated locking device. For this purpose, the sliding rod will be modified by adding on it a shape concave or convex, or a hole (15) placed on it, so as to allow its locking in the extended position out of its housing, by insertion of an object in / on / against said shape, which will block the rod out against the branch to prevent the return and cancel the spring restoring force.
H. Un dispositif de charnière élastique existant peut avantageusement être amélioré pour en plus de son fonctionnement normal permettant de maintenir la branche de lunettes (3) en position ouverte ou repliée, disposer d'un mode maintenance intégrant le procédé A. Le dispositif de charnière améliorée permet lorsqu'on sort suffisamment la tige coulissante (4) de son logement (3b) d'atteindre une position stable dans laquelle la tige coulissante (4) reste bloquée sortie de son logement (3b), ce qui permet d'atteindre le mode maintenance et de réparer plus aisément des lunettes. Le blocage de la tige coulissante (4) sortie peut éventuellement nécessiter l'opération d'un actionneur de blocage. Une seconde action telle que tirer la tige coulissante (4) encore plus loin en avant, et/ou agir une nouvelle fois sur l' actionneur de blocage, ou encore agir sur un actionneur de déblocage permet le retour de la tige coulissante dans son logement sous l'effet de la force de rappel. On quitte alors le mode maintenance de la charnière pour retourner au fonctionnement normal de la charnière élastique.H. An existing elastic hinge device can advantageously be improved for in addition to its normal operation to maintain the glasses branch (3) in the open or folded position, have a maintenance mode incorporating the method A. The hinge device improved, when the sliding rod (4) is sufficiently out of its seat (3b) to reach a stable position in which the sliding rod (4) remains locked out of its seat (3b), which makes it possible to reach the maintenance mode and to repair glasses more easily. The locking of the sliding rod (4) output may possibly require the operation of a locking actuator. A second action such as pulling the sliding rod (4) further forward, and / or act again on the locking actuator, or act on an unlocking actuator allows the return of the sliding rod in its housing under the effect of the restoring force. We then leave the maintenance mode of the hinge to return to normal operation of the elastic hinge.
Un dispositif réalisé selon l'invention permet pour toutes les charnières élastiques de bloquer la tige coulissante (4) en position sortie et ce sans avoir à utiliser la monture (2) , pour pouvoir mettre en alignement les trous de passage de vis de la tige coulissante (4) et celui de la partie fixe de la charnière (7) , et ainsi introduire le système de fixation (1) dans cet alignement sans plus aucune difficulté.A device made according to the invention allows for all elastic hinges to lock the sliding rod (4) in the extended position and without having to use the mount (2), to be able to align the screw holes of the stem sliding (4) and that of the fixed part of the hinge (7), and thus introduce the fastening system (1) in this alignment without any difficulty.
Un dispositif réalisé selon l'invention permet également de faciliter le démontage de la branche en maintenant la tige coulissante (4) de la charnière sortie, et en annulant ainsi la force de rappel du ressort, qui sinon contraint le système de fixation (1) de la charnière de la branche et rend son démontage difficile. Pour ce faire, il suffit d'écarter la branche, puis de mettre en action le dispositif de blocage de la tige coulissante (4) .A device made according to the invention also makes it possible to facilitate disassembly of the branch by holding the sliding rod (4) of the hinge out, and thus canceling the restoring force of the spring, which otherwise forces the fastening system (1). of the hinge of the branch and makes dismounting difficult. To do this, simply remove the branch, then put into action the locking device of the sliding rod (4).
Une réalisation possible, d'un dispositif selon l'invention comprendra un corps (5) muni d'une mâchoire composée par les éléments (8) et (9) , disposant d'un moyen de serrage qui, dans le cas présenté, est réalisé par une vis avec une molette (6) . Ce dispositif et son fonctionnement sont représentés sur les figures 3 et 4.One possible embodiment of a device according to the invention will comprise a body (5) provided with a jaw composed of elements (8) and (9), having a clamping means which, in the case presented, is achieved by a screw with a knob (6). This device and its operation are shown in FIGS. 3 and 4.
Les mâchoires (8) et (9) , préalablement placées sur la tige coulissante (4) permettent son pincement et son blocage par l'action du moyen de serrage (6), neutralisant ainsi l'effet rappel du ressort qui permet l'élasticité de la branche.The jaws (8) and (9), previously placed on the sliding rod (4) allow its clamping and locking by the action of the clamping means (6), thereby neutralizing the spring return effect which allows the elasticity of the branch.
Les mâchoires (8) et (9) devront pour le dispositif de blocage puisse fonctionner sur toutes les charnières de branches élastiques, être suffisamment peu épaisses pour ne pas gêner la mise en place de la branche, et suffisamment épaisses pour l'efficacité du blocage. L'idéal au niveau de l'épaisseur des mâchoires se situe autour de 0,5 mm. L'expérience montre qu'un parallélisme rigoureux des mâchoires est de nature à optimiser le blocage. L' écartement optimal des mâchoires se situe entre 2mm et 3 mm, compte tenu de la configuration usuelle des charnières élastiques. L'élasticité de l'articulation de la mâchoire devra toutefois permettre une ouverture légèrement supérieure en cas de besoin. Les forces mises en œuvre étant pour le blocage étant importantes, la matière utilisée pour la réalisation des mâchoires doit être très dure pour assurer une longévité correcte. Dans la réalisation prise en exemple, on utilise un acier très dur, recuit trempé .The jaws (8) and (9) must for the locking device can operate on all the hinges of elastic branches, be sufficiently thin so as not to hinder the establishment of the branch, and sufficiently thick for the effectiveness of the blocking . The ideal thickness of the jaws is around 0.5 mm. Experience shows that a rigorous parallelism of the jaws is likely to optimize blocking. The optimum spacing of the jaws is between 2mm and 3mm, taking into account the usual configuration of the elastic hinges. The elasticity of the articulation of the jaw will however allow a slightly greater opening when necessary. The forces used being for the blocking being important, the material used for the realization of the jaws must be very hard to ensure a correct longevity. In the embodiment taken as an example, a very hard, annealed hardened steel is used.
Une fois la pièce (5) et en particulier ses mâchoires (8) et (9) mises en place, la tige coulissante (4) peut être tiré en avant vers l'extérieur de son logement (3b) , par exemple avec un outil pointu en faisant levier sur le corps (5) , ou avec une pince, ou encore avec la monture elle-même, et ensuite bloqué par le moyen de serrage (6) .Once the piece (5) and in particular its jaws (8) and (9) in place, the sliding rod (4) can be pulled forwards out of its housing (3b), for example with a tool point levering on the body (5), or with a clamp, or with the mount itself, and then blocked by the clamping means (6).
La mise en œuvre de l'assemblage branche/monture, devient alors très simple car le système de fixation (1) peut être placé sans difficulté grâce à la neutralisation de l'action du ressort de rappel du tenon (4) et ainsi permettre l'alignement du passage de vis des éléments tige coulissante (4) et partie fixe de la charnière (7) .The implementation of the assembly branch / mount, then becomes very simple because the fastening system (1) can be placed without difficulty through the neutralization of the action of the return spring of the post (4) and thus allow the alignment of the screw passage of the sliding rod elements (4) and fixed part of the hinge (7).
Pour une réalisation optimisée et économique, le corps (5) du dispositif selon l'invention, son ressort et sa charnière d'ouverture, ainsi que la mâchoire sont intégrés et réalisés dans une pièce d'un seul tenant, fabriquée dans un acier très dur, recuit, et trempé, conjuguant ainsi les propriétés de flexibilité et de souplesses requises pour le comportement du dos de l'outil (5b) en tant que articulation et ressort d' écartement, et les propriétés de dureté requises pour les lames de la mâchoire (8) et (9) .For an optimized and economical embodiment, the body (5) of the device according to the invention, its spring and its opening hinge, as well as the jaw are integrated and made in a single piece, manufactured in a very high-grade steel. hard, annealed, and hardened, thus combining the flexibility and flexibility properties required for the behavior of the back of the tool (5b) as articulation and spacing spring, and the properties of hardness required for the blades of the jaw (8) and (9).
L'outil pointu permettant de tirer la tige coulissante hors de son logement pourrait de manière très simple être intégré au dispositif de blocage, en étant par exemple articulé sur la partie frontale du dispositif, au dessus de la mâchoire (8) .The pointed tool for pulling the sliding rod out of its housing could very simply be integrated in the locking device, for example being articulated on the front of the device, above the jaw (8).
Pour optimiser sa prise en main, et limiter son encombrement, le dispositif de blocage mesure dans sa plus grande longueur autour de 5 cm. La partie arrière de l'outil (5b), située à l'opposé des mâchoires peut avantageusement comporter sur chacun de ses cotés une encoche (5c) pour laisser entrer la branche de la monture, et permettre une orthogonalité parfaite entre les mâchoires (8) et (9) et la tige coulissante (4) . Ces encoches, permettent également de réduire la dureté du ressort constitué par cette partie arrière, et rendent l'outil plus facile a serrer.To optimize its handling, and limit its size, the locking device measures in its greatest length around 5 cm. The rear part of the tool (5b), located opposite the jaws can advantageously comprise on each of its sides a notch (5c) to let in the branch of the frame, and allow a perfect orthogonality between the jaws (8). ) and (9) and the sliding rod (4). These notches, also reduce the hardness of the spring formed by the rear portion, and make the tool easier to tighten.
La réalisation d'un dispositif selon le principe G est représentée figure 5. Elle consiste à ajouter sur la tige coulissante (4) d'une charnière existante un trou ou une forme convexe, qui pourrait ici être un cylindre (15) pour permettre une fois la tige coulissante sortie de bloquer son retour grâce à l'insertion d'une objet quelconque à l'intérieur du trou (15) ou entre le cylindre (15) et le bord de la branche.The embodiment of a device according to the principle G is represented in FIG. 5. It consists in adding on the sliding rod (4) of an existing hinge a hole or a convex shape, which could here be a cylinder (15) to allow a Once the sliding rod out to block his return through the insertion of any object inside the hole (15) or between the cylinder (15) and the edge of the branch.
La figure 6 décrit un dispositif selon le principe H. Ce dispositif permet en tirant la tige coulissante suffisamment à l'extérieure de son logement d'atteindre une position ou cette dernière reste bloquée, et ne rentre plus dans son logement sous l'effet de la force de rappel. La charnière et alors en position de maintenance et on peut réparer les lunettes sans être gêné par le ressort de la charnière. En tirant la tige au-delà de cette position, on la débloque et on lui permet de retourner dans son logement, pour redonner à la charnière un fonctionnement normal. Ce dispositif se réalise par exemple en rajoutant à la branche une lamelle (10) flexible latéralement et verticalement, avec une tête qui viendra lorsque on tirera suffisamment la tige vers l'extérieur, se loger dans une encoche prévue dans la tige coulissante (4) et ainsi bloquer son retour au point (13) pour permettre la mise en place ou le démontage de la branche sans soucis avec le ressort de rappel. Une fois l'opération terminée, le fait de tirer légèrement en avant la tige coulissante (4) fait passer la tête de la lamelle flexible (10) au dessus de la tige coulissante (4) grâce au plan incliné (11) de la tête, qui va glisser sur l'encoche (12). Ceci a pour effet de libérer la tige coulissante qui peut reprendre sa place, rentrée dans son logement. A ce moment là la tête de la lamelle flexible (10) sera revenue contre le côté de la tige coulissante (4) , au moment où elle sera entrée dans la zone (14) de la tige coulissante. Le dispositif de blocage est prêt à être actionné à nouveau en tirant la tige coulissante. Dans cette réalisation, on a délibérément pris le parti d'une automatisation totale de la mise de la tige coulissante en position maintenance et du retour en position normale. On pourrait imaginer d'autres solutions plus simples utilisant des actionneurs mis à disposition du réparateur de lunettes pour activer le blocage et/ou le déblocage de la tige.FIG. 6 describes a device according to the principle H. This device makes it possible, by pulling the sliding rod sufficiently outside its housing, to reach a position where the latter remains locked, and no longer returns to its housing under the effect of the restoring force. The hinge and then in the maintenance position and we can repair the glasses without being bothered by the spring of the hinge. Pulling the rod beyond this position, it is unlocked and allowed to return to its housing, to restore the hinge normal operation. This device is realized for example by adding to the branch a slat (10) flexible laterally and vertically, with a head that will come when the rod is pulled sufficiently outwards, to lodge in a notch provided in the sliding rod (4) and thus block its return to point (13) to allow the establishment or disassembly of the branch without worries with the return spring. Once the operation is completed, the fact of pulling slightly forward the sliding rod (4) passes the head of the flexible blade (10) above the sliding rod (4) through the inclined plane (11) of the head , which will slide on the notch (12). This has the effect of releasing the sliding rod that can resume its place, returned to its home. At this time the head of the flexible blade (10) will be returned against the side of the sliding rod (4), when it will enter the area (14) of the sliding rod. The locking device is ready to be operated again by pulling the sliding rod. In this embodiment, it was deliberately made to fully automate the setting of the sliding rod in the maintenance position and return to normal position. One could imagine other simpler solutions using actuators made available to the eyeglass repairer to activate the locking and / or unlocking of the rod.

Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet. The embodiments according to the invention are described in the foregoing by way of example. It is understood that the skilled person is able to realize different variants of the invention without departing from the scope of the patent.
