MONTURE DE LUNETTES A BRANCHES EN LAMES DE MÉTAL FRAME OF METAL GLAZE WINDOW GLASSES
AMOVIBLES CLIPSEES REMOVABLE CLIPSES
Domaine de l'invention Field of the invention
La présente invention a pour objet une monture de lu- nettes à branches articulées, amovibles, comprenant pour chaque branche une articulation formée de deux éléments séparables, un élément de palier et un élément de pivot, associés respectivement à l'une des deux parties de la monture de lunettes, le tenon de la face et une branche, pour tenir la branche en position repliée ou en position dé- ployée.  The subject of the present invention is a mount for detachable hinged arm blades comprising, for each branch, a hinge formed of two separable elements, a bearing element and a pivot element, respectively associated with one of the two parts of the hinge. the spectacle frame, the tenon of the face and a branch, to hold the branch in the folded position or in the deployed position.
Etat de la technique  State of the art
On connaît un tel type de monture ainsi réalisés. En particulier, selon le document FR 1 1 59 757. Chaque branche a une articulation formée d'une pièce de palier et d'une pièce de pivot enclipsée l'une dans l'autre. La pièce de palier est un bloc fixé à la branche ou au tenon et elle a un côté formant une surface principale d'appui et un côté adjacent formant une surface secondaire d'appui, ces surfaces étant parallèles à l'axe d'articulation pour définir la position dépliée et la position repliée de la branche. Le palier a un logement pour recevoir l'axe d'articulation porté par une pièce de pivot ayant une chape portant le pivot et muni d'un ressort. Cette monture a l'avantage de permettre un échange facile des branches par un simple mouvement d'engagement et de clipsage de l'axe. Mais la structure est relativement complexe et présente une certaine épaisseur côté intérieur de la monture, ce qui peut être considéré comme dans certains cas comme gênant.  Such a type of frame thus produced is known. In particular, according to the document FR 1 1 59 757. Each branch has a hinge formed of a bearing part and a pivot piece inserted into one another. The bearing part is a block attached to the branch or post and has a side forming a main bearing surface and an adjacent side forming a secondary bearing surface, these surfaces being parallel to the hinge pin for define the unfolded position and the folded position of the branch. The bearing has a housing for receiving the hinge pin carried by a pivot piece having a yoke bearing the pivot and provided with a spring. This mount has the advantage of allowing easy exchange branches by a simple movement of engagement and clipping of the axis. But the structure is relatively complex and has a certain thickness on the inside of the frame, which can be considered in some cases as embarrassing.
But de l'invention  Purpose of the invention
La présente invention a pour but de développer une monture de lunettes à branches articulées amovibles qui soit d'une réalisation et d'une structure particulièrement simple et facilitant le montage et le démontage des branches de la monture.  The object of the present invention is to develop a spectacle frame with articulated removable arms which is of a particularly simple construction and structure and facilitates the assembly and disassembly of the branches of the frame.
Exposé et avantages de l'invention  Description and advantages of the invention
A cet effet, la présente invention a pour objet une monture de lunettes du type défini ci-dessus caractérisée en ce que :  For this purpose, the subject of the present invention is a spectacle frame of the type defined above characterized in that:
le tenon comporte une découpe bordée par deux languettes de base barrées près de leurs extrémités par un axe transversal, l'extrémité de la branche a une languette principale cintrée en une boucle couverte pour former un palier d'axe transversal et de section correspondant à celle de l'axe du tenon, cette languette principale étant bordée par deux languettes latérales droites, à l'assemblage, les languettes latérales venant sur le côté extérieur des languettes de base et le palier de la languette principale se clipsant côté intérieur sur l'axe du tenon. the tenon comprises a cut-out bordered by two base tabs barred near their ends by a transverse axis, the end of the branch has a main tongue bent in a covered loop to form a bearing of transverse axis and section corresponding to that of the axis of the tenon, this main tongue being bordered by two straight lateral tongues, to the assembly, the lateral tabs coming on the outer side of the base tabs and the bearing of the main tab clipping on the inner side on the axis of the tenon.
Cette monture de lunettes est d'une réalisation particulièrement simple et le montage de la branche sur l'axe du tenon se fait par un simple mouvement d'engagement et de clipsage. L'enlèvement de la branche se fait par un mouvement inverse tout aussi simple en jouant, là encore, sur l'élasticité de la languette principale et des languettes latérales.  This eyeglass frame is particularly simple and the assembly of the branch on the axis of the tenon is by a simple movement of engagement and clipping. The removal of the branch is done by a reverse movement just as simple playing, again, on the elasticity of the main tongue and side tabs.
Suivant une autre caractéristique, la découpe du tenon est occupée par une languette de retenue plus courte que la languette de base pour laisser par rapport à l'axe le passage pour la languette principale et le palier de la branche et la languette principale est prolongée au-delà de la boucle formant le palier par une patte venant sur le dessus de la languette de retenue lorsque la branche est en position dépliée.  According to another feature, the cutting of the tenon is occupied by a shorter retaining tongue than the base tongue to leave relative to the axis the passage for the main tongue and the bearing of the branch and the main tongue is extended to beyond the loop forming the bearing by a lug coming on the top of the retaining tongue when the branch is in the unfolded position.
La languette de retenue complète avantageusement la retenue de la branche dans le prolongement du tenon, en position déployée tout en permettant un mouvement de sur-ouverture par la déformation élastique de la languette de retenue, de la patte de la languette principale et des languettes latérales qui se déforment élastique- ment en même temps que la languette principale. Ce mouvement de sur-ouverture est rappelé élastiquement en position normale d'ouverture par la réaction élastique des différents éléments de l'articulation ainsi déformés. Cette réaction élastique est nulle lorsque la branche est dans l'alignement de la languette de retenue, les languettes latérales étant appuyées sur les languettes de base du tenon.  The retaining tab advantageously completes the retention of the branch in the extension of the tenon, in the extended position while allowing an over-opening movement by the elastic deformation of the retaining tongue, the lug of the main tongue and the lateral tongues. which deform elastically at the same time as the main tongue. This over-opening movement is resiliently returned to the normal opening position by the elastic reaction of the various elements of the joint thus deformed. This elastic reaction is zero when the leg is in alignment with the retaining tongue, the lateral tongues being supported on the base tabs of the tenon.
Suivant une autre caractéristique, la languette de retenue est décalée par rapport au plan du tenon de l'épaisseur de la matière vers l'intérieur de la monture et la patte prolongeant la languette principale est sensiblement dans le plan de la languette principale. Grâce à ce décalage, l'épaisseur globale de l'articulation est réduite et la patte de la branche est retenue escamotée au-dessus de la languette de retenue dans la découpe du tenon. According to another feature, the retaining tab is offset from the plane of the tenon of the thickness of the material towards the inside of the frame and the tab extending the main tongue is substantially in the plane of the main tongue. Due to this shift, the overall thickness of the joint is reduced and the tab of the branch is retained retracted over the retaining tab in the cutout of the tenon.
Suivant une autre caractéristique avantageuse, les languettes de base sont prolongées au-delà de l'axe barrant la découpe pour constituer des surfaces d'appui contre lesquelles viennent les languettes latérales par déformation élastique pour le maintien de la branche en position repliée.  According to another advantageous characteristic, the base tabs are extended beyond the axis blocking the cutout to form bearing surfaces against which come the lateral tabs by elastic deformation for holding the branch in the folded position.
Cette déformation élastique pour le maintien de la branche en position repliée est une solution particulièrement simple et efficace compatible avec la simplicité de l'organisation de l'articulation entre la branche et le tenon.  This elastic deformation for maintaining the branch in the folded position is a particularly simple and effective solution compatible with the simplicity of the organization of the articulation between the branch and the tenon.
Suivant une autre caractéristique, le procédé de fabrication de la monture au moins de l'articulation est très simple puisqu'il consiste, de façon avantageuse et préférentielle, à découper le tenon et au moins l'extrémité de la branche dans une pièce en tôle par exemple en acier qui est ensuite pliée partiellement et cintrée pour donner leur forme aux éléments de l'articulation et ensuite l'axe est soudé sur le tenon.  According to another feature, the manufacturing method of the frame at least the joint is very simple since it consists, advantageously and preferentially, in cutting the tenon and at least the end of the branch in a sheet metal part. for example steel which is then partially bent and bent to shape the elements of the joint and then the axis is welded to the post.

Description d'un mode de réalisation de l'invention  Description of an embodiment of the invention
Selon la figure 1 , l'invention a pour objet une monture de lunettes 1 à branches 3 articulées, amovibles, dont seule la partie correspondant à l'articulation d'une branche 3 sur son tenon 1 1 est représentée, la face 10 étant simplement esquissée partiellement.  According to FIG. 1, the subject of the invention is an eyeglass frame 1 with articulated, detachable branches 3, of which only the part corresponding to the articulation of a limb 3 on its post 1 1 is shown, the face 10 being simply partially sketched.
La structure des deux articulations de chaque côté de la face 10 étant la même, la description se limitera à une seule articulation. Par convention pour faciliter les explications, il sera fait référence au côté extérieur de la monture 1 et à son côté intérieur. Le côté intérieur est celui tourné vers la tête de l'utilisateur.  The structure of the two joints on each side of the face 10 being the same, the description will be limited to a single articulation. By convention to facilitate explanations, reference will be made to the outer side of the frame 1 and to its inner side. The inner side is the one facing the user's head.
Selon la figure 1 , la monture se compose de la face 10 portant de chaque côté un tenon 1 1. Ce tenon 1 1 est muni d'une découpe 12 ouverte vers le côté tourné vers la branche 3. Cette découpe est délimitée par deux languettes de base 13. Près de l'extrémité libre, les languettes de base 13 portent un axe transversal 2 qui est l'axe d'articulation de la branche 3. Les extrémités des languettes de base 13 dépassent par un léger prolongement 131 , la position de l'axe d'articulation 2. La découpe 12 est en partie occupée par une languette de retenue 14 décalée par rapport au plan du tenon 1 1 pour venir en position décalée d'une épaisseur, côté intérieur, de la monture.  According to Figure 1, the frame consists of the face 10 carrying on each side a post 1 1. This pin 1 1 is provided with a cutout 12 open towards the side facing the branch 3. This cutout is delimited by two tabs 13. Near the free end, the base tabs 13 have a transverse axis 2 which is the axis of articulation of the branch 3. The ends of the base tabs 13 protrude by a slight extension 131, the position of the hinge pin 2. The cutout 12 is partly occupied by a retaining tab 14 offset from the plane of the post 1 1 to come in a position offset by a thickness, on the inside, of the frame.
Dans cet exemple, l'ensemble du tenon 1 1 est constitué par une pièce plate, par exemple une pièce de tôle dans laquelle aura été réalisée la découpe 12 et la formation par cintrage et pliage de la languette de retenue 14.  In this example, the entire tenon 1 1 is constituted by a flat piece, for example a sheet metal part in which the cut 12 has been made and the formation by bending and folding of the retaining tongue 14.
L'axe transversal 2 est soudé aux deux languettes de base 13 sur le côté intérieur. Pour faciliter la fixation de l'axe, celui-ci comporte deux méplats 21 venant s'appliquer contre la face intérieure des deux languettes de base 13. Les méplats 21 apparaissent sur les côtés du tenon 1 1 dans les différentes figures. Ils permettent aussi de rapprocher l'axe géométrique (xx) de l'articulation ou de l'axe transversal 2 par rapport à la face intérieure du tenon 1 1 et de réduire ainsi l'épaisseur de l'articulation. The transverse axis 2 is welded to the two base tabs 13 on the inner side. To facilitate attachment of the axis, it comprises two flats 21 coming to rest against the inner face of the two base tabs 13. The flats 21 appear on the sides of the pin 1 1 in the different figures. They also allow bring the geometric axis (xx) of the articulation or the transverse axis 2 relative to the inner face of the post 1 1 and thus reduce the thickness of the joint.
La branche 3 destinée à être fixée à l'axe d'articulation 2 porté par le tenon 1 1 comporte une languette principale 31 découpée dans la surface de l'extrémité de la branche 3. Cette languette principale 31 est bordée par deux languettes latérales 32. La languette principale 31 comporte une extrémité cintrée 310 formant un palier de section correspondant à celle de l'axe 21 et se refermant de préférence sur plus de 180° pour permettre le clipsage du palier 310 et sa retenue sur l'axe 2 comme cela sera vu ci-dessous.  The branch 3 intended to be fixed to the hinge pin 2 carried by the pin 1 1 comprises a main tongue 31 cut in the surface of the end of the branch 3. This main tongue 31 is bordered by two lateral tongues 32 The main tongue 31 has a curved end 310 forming a bearing of section corresponding to that of the axis 21 and closing preferably over more than 180 ° to allow clipping of the bearing 310 and its retention on the axis 2 as this will be seen below.
Le palier cintré 310 est prolongé par une patte 31 1.  The arched bearing 310 is extended by a lug 31 1.
Les languettes latérales 32 et la languette principale 31 sont de préférence découpées d'abord dans la surface plane de l'extrémité de la branche 3. La languette principale 31 non encore cintrée est plus longue que les deux languettes latérales 32. Puis la languette principale 31 est cintrée vers son extrémité pour former le palier 310. La languette principale 31 est séparée des languettes latérales 32 par une ligne de séparation 33 allongeant chacune des languettes 31 , 32, pour lui donner une certaine élasticité, nécessaire à la mise en place et au fonctionnement de l'articulation.  The lateral tabs 32 and the main tongue 31 are preferably cut first in the flat surface of the end of the branch 3. The main tongue 31 not yet bent is longer than the two lateral tongues 32. Then the main tongue 31 is bent towards its end to form the bearing 310. The main tongue 31 is separated from the lateral tongues 32 by a dividing line 33 extending each of the tongues 31, 32, to give it a certain elasticity, necessary for the installation and the operation of the joint.
La figure 1A montre en vue en coupe les différents éléments de la structure du tenon 1 1 et de l'extrémité de la branche 3 pour les parties concernées par l'articulation. Elle met en évidence la forme cylindrique de section circulaire du palier 310 qui se referme à sa base 310a, 310b pour l'enclipsage sur l'axe 2.  Figure 1A shows in sectional view the various elements of the structure of the pin 1 1 and the end of the leg 3 for the parts concerned by the joint. It highlights the cylindrical shape of circular section of the bearing 310 which closes at its base 310a, 310b for clipping on the axis 2.
Les figures 2, 2A montrent l'assemblage de la branche 3 au tenon 1 1 par le clipsage du palier 310 sur l'axe 2.  FIGS. 2, 2A show the assembly of the branch 3 to the pin 1 1 by the clipping of the bearing 310 on the axis 2.
La figure 2 montre la correspondance des dimensions et notamment la largeur lo de la languette principale 31 au moins au niveau de sa partie formant le palier cintré 310 qui correspond à la largeur h de la découpe 12 de sorte que la branche 3 est non seulement articulée autour de l'axe 2 mais elle est également guidée dans une certaine mesure entre les deux bords de la découpe 12 par son contact avec la tranche du palier cintré 310. En position déployée comme à la figure 2, ce maintien est en plus renforcé par la venue de la patte 31 1 dans la découpe 12 au- dessus de la languette de retenue 13 ce qui renforce la tenue au basculement entre la branche 3 et le tenon 1 1 dans le plan de l'assemblage tenon/ branche . FIG. 2 shows the correspondence of the dimensions and in particular the width lo of the main tongue 31 at least at its part forming the curved bearing 310 which corresponds to the width h of the cutout 12 so that the branch 3 is not only articulated around the axis 2 but it is also guided to some extent between the two edges of the cutout 12 by its contact with the edge of the curved bearing 310. In the extended position as in FIG. 2, this retention is furthermore reinforced by the coming of the tab 31 1 in the cutout 12 above the retaining tab 13, which strengthens the resistance to tilting between the branch 3 and the tenon 1 1 in the plane of the tenon / branch assembly.
La figure 2A montre en coupe la position des éléments assemblés et en particulier l'appui de la patte 31 1 sur la languette de retenue 14. La surface extérieure du tenon 1 1 et de la branche 3 et de sa patte 31 1 sont pratiquement coplanaire, les languettes latérales 31 venant pardessus les languettes de base 13.  2A shows in section the position of the assembled elements and in particular the support of the tab 31 1 on the retaining tongue 14. The outer surface of the post 1 1 and the branch 3 and its tab 31 1 are substantially coplanar , the lateral tongues 31 coming over the base tabs 13.
La figure 3 montre la position repliée de la branche par rapport au tenon 1 1. Dans cette position, les deux languettes latérales 32 s'appuient sur le chant des deux prolongements 131 des languettes de base 13 par déformation élastique des languettes 32 combinée à la déformation de la languette principale 31. Ainsi lorsque le plan des languettes latérales 32 est pivoté autour de l'axe 2 en faisant avec le plan du tenon 1 1 inférieur un angle à 90°, la branche est maintenue dans cette position repliée. Pour passer en position déployée, il faut dépasser l'angle de la position métastable correspond sensiblement à un angle droit entre la branche 3 et le tenon 1 1.  FIG. 3 shows the folded position of the branch relative to the post 1 1. In this position, the two lateral tongues 32 rest on the edge of the two extensions 131 of the base tongues 13 by elastic deformation of the tongues 32 combined with the deformation of the main tongue 31. Thus when the plane of the lateral tongues 32 is pivoted about the axis 2 by making the plane of the tenon 1 lower a 90 ° angle, the branch is maintained in this folded position. To move into the deployed position, it is necessary to exceed the angle of the metastable position substantially corresponds to a right angle between the branch 3 and the pin 1 1.
Le détachement de la branche 3 par rapport au tenon 1 1 se fait par un simple appui sur la patte 31 1 du palier cintré 310 pour déclipser le palier de l'axe 2 et ensuite tirer simplement la branche 3 par exemple à partir de la position repliée représentée à la figure 3.  The detachment of the branch 3 relative to the post 1 1 is made by a simple pressing on the tab 31 1 of the bent bearing 310 to unclip the bearing of the axis 2 and then simply pull the branch 3 for example from the position folded shown in Figure 3.
La mise en place de la branche 3 se fait en effectuant un mouvement inverse en appuyant d'abord la patte 31 1 contre l'axe 2 et en fléchissant légèrement la languette principale 31 suffisamment pour passer sur l'axe 2 jusqu'à ce que le palier 310 puisse s'engager sur l'axe 2.  The establishment of the branch 3 is done by performing a reverse movement by first pressing the lug 31 1 against the axis 2 and slightly bending the main tongue 31 enough to pass on the axis 2 until the bearing 310 can engage on the axis 2.
La monture de lunettes se fabrique de manière simple par le découpage des tenons et au moins des extrémités des branches dans une pièce en tôle par exemple en acier. L'axe 2 constitué par une pièce cylindrique de section circulaire est soudé sur le tenon après mise en forme de la languette de retenue. Pour l'extrémité de la branche, après le découpage des languettes 31 , 32, la languette principale est cintrée pour former le palier 310 et le prolongement constituant la patte 31 1. The eyeglass frame is manufactured in a simple manner by cutting the tenons and at least the ends of the branches in a piece of sheet metal, for example steel. The axis 2 consisting of a cylindrical piece of circular section is welded to the stud after shaping of the retaining tongue. For the end of the branch, after the cutting of the tongues 31, 32, the main tongue is bent to form the bearing 310 and the extension constituting the leg 31 1.
