Description

Lunette avec branches à ouverture automatique  Bezel with automatically opening arms
Domaine technique et état de l'art  Technical field and state of the art
La présente invention se rapporte à une lunette du type comprenant une façade optique ou solaire et deux branches, chaque branche étant reliée à la une monture ou directement à la façade par l'intermédiaire d'un tenon et d'une articulation associée. The present invention relates to a telescope of the type comprising an optical or solar facade and two branches, each branch being connected to a mount or directly to the facade via a pin and an associated joint.
Le document Dl = FR 2 950 706 décrit une telle lunette dont l'articulation élastique est réalisée de sorte que la branche soit mobile entre une position fermée et une position ouverte avec un effet bistable de la branche ayant pour conséquence de maintenir la branche en position ouverte ou en position fermée. Pour réduire l'effort à exercer pour ouvrir ou fermer une branche, le document Dl propose de limiter la surface des zones d'appui de la branche sur le tenon. Toutefois, ceci a pour effet secondaire d'entraîner des oscillations de la branche lorsqu'elle arrive vers sa position ouverte. Aussi, pour supprimer ces oscillations, le document Dl propose en complément l'ajout de deux aimants renforçant la stabilité de la position ouverte de la branche et supprimant ainsi les oscillations de la branche lorsqu'elle arrive en position ouverte.  The document Dl = FR 2 950 706 describes such a telescope whose elastic articulation is made so that the branch is movable between a closed position and an open position with a bistable effect of the branch resulting in maintaining the branch in position open or in closed position. To reduce the effort required to open or close a branch, the document Dl proposes to limit the area of the support zones of the branch on the tenon. However, this has the side effect of causing oscillations of the branch when it arrives to its open position. Also, to eliminate these oscillations, the document Dl proposes in addition the addition of two magnets reinforcing the stability of the open position of the branch and thus removing the oscillations of the branch when it arrives in the open position.
Dans les faits, les moyens magnétiques proposés réduisent également l'effort à fournir pour ouvrir la branche, mais uniquement après que la branche ait passé le point de bascule entre la position fermée et la position ouverte. Un effort reste donc à fournir par l'utilisateur pour ouvrir les branches de sa lunette, ce qui nécessite l'usage de ses deux mains.  In fact, the proposed magnetic means also reduce the effort required to open the branch, but only after the branch has passed the tipping point between the closed position and the open position. An effort therefore remains to be provided by the user to open the branches of his telescope, which requires the use of both hands.
Description de l'invention L'invention propose une nouvelle lunette ne présentant pas tout ou partie des inconvénients des lunettes selon l'art antérieur rappelé ci-dessus. DESCRIPTION OF THE INVENTION The invention proposes a new telescope that does not have all or some of the disadvantages of the spectacles according to the prior art mentioned above.
Plus précisément, l'invention propose une lunette du type comprenant une façade optique ou solaire et deux branches ; chaque branche est reliée à une monture ou directement à la façade par l'intermédiaire d'un tenon et d'une articulation associée. La lunette selon l'invention est caractérisée en ce que l'articulation de branche comprend deux éléments de liaison ; l'un des éléments de liaison est un élément magnétique et l'autre des éléments de liaison est un élément magnétique ou ferromagnétique ; un premier élément de liaison est solidaire du tenon et un deuxième élément de liaison est solidaire de la branche ; enfin, la branche est mobile entre : More specifically, the invention provides a telescope of the type comprising an optical or solar facade and two branches; each branch is connected to a frame or directly to the facade via a pin and an associated joint. The bezel according to the invention is characterized in that the branch joint comprises two connecting elements; one of the connecting elements is a magnetic element and the other of the connecting elements is a magnetic or ferromagnetic element; a first connecting element is integral with the post and a second connecting element is integral with the branch; finally, the branch is mobile between:
• une position ouverte stable où une zone de contact du premier élément de liaison et une zone de contact maximale du deuxième élément de liaison forment ensemble un plan de joint à l'ouverture de surface maximale, une force d'attraction magnétique de l'un au moins des éléments de liaison maintenant les deux éléments de liaison solidaires, et • une position fermée instable où la zone de contact du premier élément de liaison et une zone de contact minimale du deuxième élément de liaison forment ensemble un plan de joint à la fermeture de surface minimale de sorte que la force d'attraction magnétique est suffisante pour appeler la branche en position ouverte. A stable open position where a contact area of the first connection element and a maximum contact area of the second connection element together form a joint plane at the maximum surface opening, a magnetic attraction force of one at least linking elements holding the two integral connecting elements, and An unstable closed position where the contact area of the first connection element and a minimum contact area of the second connection element together form a joint plane at the minimum surface closure so that the magnetic attraction force is sufficient to call the branch in the open position.
La position fermée étant instable, les branches s'ouvrent automatiquement grâce à la force d'attraction magnétique dès qu'elles sont libérées de toute contrainte. Il suffit donc de prendre la lunette dans une main pour ouvrir les branches, sans aucun effort sur les branches. Comme on le verra lieux plus loin dans des exemples, la surface du plan de joint entre la branche et le tenon est bien plus importante lorsque la branche est ouverte que lorsque la branche est fermée. Il s'ensuit que la force d'attraction magnétique est plus importante lorsque la branche est fermée que lorsqu'elle est ouverte. The closed position being unstable, the branches open automatically thanks to the magnetic attraction force as soon as they are released from any constraint. So just take the bezel in one hand to open the branches, without any effort on the branches. As will be seen later in the examples, the surface of the joint plane between the branch and the post is much larger when the branch is open than when the branch is closed. It follows that the magnetic attraction force is greater when the branch is closed than when it is open.
Ainsi, pour maintenir les branches fermées, dans la mesure où la position fermée est instable, il est nécessaire de maintenir un petit effort sur les branches pour les maintenir fermées. Pour cela, il suffit de poser la lunette par exemple sur une table, branches sous la façade optique ; le poids de la façade optique exerce alors une force de pesanteur suffisante pour maintenir les branches fermées. Il est aussi possible de ranger la lunette dans un étui. Inversement, en position ouverte, la force d'attraction magnétique est suffisante pour un bon maintien de la branche solidaire du tenon sans qu'il soit nécessaire d'ajouter à l'articulation un moyen de fixation tel moyen comprenant un axe, un vis, un piston, un ressort, etc. La réalisation de l'articulation est ainsi très facile et les coûts de réalisation sont quasi-nuls. De plus, les branches de la lunette sont aisément démontables, sans outil, en exerçant simplement à la main une force supérieure à la force magnétique. Les branches de la lunette deviennent ainsi interchangeables, sans outil et sans effort susceptible d'endommager l'articulation ou plus généralement l'ensemble de la lunette.  Thus, to keep the branches closed, to the extent that the closed position is unstable, it is necessary to maintain a small effort on the branches to keep them closed. For that, it is enough to put the telescope for example on a table, branches under the optical facade; the weight of the optical facade then exerts a force of gravity sufficient to keep the branches closed. It is also possible to store the glasses in a case. Conversely, in the open position, the magnetic attraction force is sufficient for a good maintenance of the integral branch of the tenon without it being necessary to add to the articulation a means of attachment such means including an axis, a screw, a piston, a spring, etc. The realization of the joint is thus very easy and the realization costs are almost zero. In addition, the branches of the bezel are easily removable, without tools, by simply exerting by hand a force greater than the magnetic force. The branches of the bezel and become interchangeable without tools and without effort likely to damage the joint or more generally the entire scope.
Selon un mode de réalisation, le premier élément de liaison est sensiblement perpendiculaire à la façade ou à la monture et le deuxième élément de liaison s'étend selon un axe longitudinal de la branche. Ainsi, le plan de joint des deux éléments de liaison en position ouverte, qui forme le plan de joint entre la branche et la façade, est positionné dans le prolongement de la branche, comme on le verra mieux plus loin.  According to one embodiment, the first connecting element is substantially perpendicular to the facade or the frame and the second connecting element extends along a longitudinal axis of the branch. Thus, the joint plane of the two connecting elements in the open position, which forms the joint plane between the branch and the facade, is positioned in the extension of the branch, as will be seen better below.
Les éléments de liaison sont par exemple des éléments plats, sensiblement parallélépipédiques, présentant chacun une face principale et des bords latéraux, et :  The connecting elements are for example flat elements, substantially parallelepipedic, each having a main face and side edges, and:
• sur le premier élément, la zone de contact est constituée d'une partie au moins de la face principale, On the first element, the contact zone consists of at least a portion of the main face,
• sur le deuxième élément, la zone de contact maximale est constituée d'une partie au moins de la face principale et la zone de contact minimale est constituée d'une partie au moins d'un bord latéral. • on the second element, the maximum contact area consists of at least a portion of the main face and the minimum contact area consists of at least a portion of a side edge.
Une telle forme permet d'obtenir une force de liaison magnétique importante en position ouverte, pour un maintien bien solidaire de la branche sur la lunette ; à l'inverse une telle forme permet d'obtenir une force d'attraction magnétique en position fermée assez faible pour un maintien en position fermée par le simple poids de la lunette et en même temps suffisante pour ouvrir automatiquement la branche dès que la branche est libérée de toute contrainte. En complément, une telle forme rend les éléments de liaison assez discrets sur la lunette, ce qui permet de soigner l'esthétisme de la lunette. Such a shape makes it possible to obtain a large magnetic connection force in the open position, for a well-secured support of the branch on the telescope; conversely, such a shape makes it possible to obtain a magnetic attraction force in the closed position that is low enough to maintain the closed position by the simple weight of the telescope and at the same time sufficient to automatically open the branch as soon as the branch is released from any constraint. In addition, such a shape makes the connection elements quite discreet on the bezel, which helps to heal the aesthetics of the bezel.
En complément', sur le deuxième élément de liaison, une arête entre la zone de contact maximale et la zone de contact minimale peut être arrondie. Cela limite la force d'attraction magnétique à appliquer pour ouvrir la branche et facilite ainsi le passage de la branche de la position fermée à la position ouverte. In addition 'to the second connecting element, an edge between the maximum contact area and the minimum contact area may be rounded. This limits the magnetic attraction force to be applied to open the branch and thus facilitates the passage of the branch from the closed position to the open position.
L'un au moins des éléments de liaison peut être un aimant, par exemple un aimant de type Néodyme. De tels aimants présentent une force magnétique importante y compris pour des aimants de petite dimension.  At least one of the connecting elements may be a magnet, for example a neodymium-type magnet. Such magnets have a large magnetic force, even for small magnets.
Selon un mode de réalisation, le premier élément de liaison est fixé dans une rainure sur une face interne du tenon. Ainsi, le premier élément est parfaitement solidaire du tenon tout en étant peu ou pas visible de l'extérieur pour conserver l'aspect esthétique de la lunette.  According to one embodiment, the first connecting element is fixed in a groove on an inner face of the tenon. Thus, the first element is perfectly secured to the post while being little or not visible from the outside to maintain the aesthetic appearance of the bezel.
Également, l'épaisseur du premier élément de liaison peut être inférieure à la profondeur de la rainure du tenon ; ainsi, deux bords de la rainure, dépassant du premier élément de liaison, , forment un moyen de guidage du deuxième élément de liaison lors d'un changement de position de la branche.  Also, the thickness of the first connecting element may be less than the depth of the groove of the post; thus, two edges of the groove protruding from the first connecting element, form a guide means of the second connecting element during a change of position of the branch.
Le deuxième élément de liaison peut quant à lui s'étendre selon l'axe longitudinal de la branche :  The second connecting element can in turn extend along the longitudinal axis of the branch:
· dans le prolongement de la branche, l'élément de liaison étant fixé à une extrémité de liaison de la branche, par exemple positionné à l'intérieur d'un évidement localisé à l'extrémité de liaison de la branche, ou • le long dè la branche, fixé sur une face extérieure de la branche ; dans ce cas le deuxième élément de liaison est de préférence, mais non nécessairement, positionné à proximité de l'extrémité de liaison de la branche. · In the extension of the branch, the connecting element being fixed to a connecting end of the branch, for example positioned inside a recess located at the connecting end of the branch, or • along from the branch, fixed on an external face of the branch; in this case the second connecting element is preferably, but not necessarily, positioned near the connecting end of the branch.
Ainsi, en position ouverte la branche s'étend dans le prolongement du tenon. Thus, in the open position the branch extends in the extension of the tenon.
La lunette selon l'invention peut encore comprendre un moyen de verrouillage agencé pour empêcher une désolidarisation non souhaitée de la branche de la lunette lors d'un changement de position de la branche. Comme cela a été dit plus haut, lorsque la branche est ouverte, la force magnétique exercée par les éléments de liaison entre eux est suffisante pour maintenir la branche bien solidaire du tenon pour un usage normal de la lunette. Dans des conditions d'usage extrême de la lunette, le moyen de verrouillage apporte une sécurité supplémentaire. Selon un mode de réalisation, le moyen de verrouillage comprend un bossage agencé pour coopérer, en position ouverte de la branche, avec un évidement correspondant ; le bossage et l'évidement correspondant sont localisés sur un plan de joint entre la branche et le tenon lorsque la branche est en position ouverte ; le bossage et l'évidement sont localisés l'un sur la branche et l'autre sur le tenon. The bezel according to the invention may further comprise a locking means arranged to prevent unwanted disconnection of the arm of the telescope during a change of position of the arm. As mentioned above, when the branch is open, the magnetic force exerted by the connecting elements between them is sufficient to maintain the branch firmly secured to the tenon for normal use of the bezel. In conditions of extreme use of the telescope, the locking means provides additional security. According to one embodiment, the locking means comprises a boss arranged to cooperate, in the open position of the branch, with a corresponding recess; the boss and the corresponding recess are located on a joint plane between the branch and the tenon when the branch is in the open position; the boss and the recess are located one on the branch and the other on the tenon.

Selon l'invention, pour chaque branche, l'articulation 20 comprend deux éléments de liaison 21, 22 ; dans les exemples représentés, les deux éléments de liaison sont des éléments magnétiques, plus précisément des aimants de type Néodyme, de forme générale parallélépipédique et sensiblement plats. Dans un exemple indicatif, l'aimant 21 a une longueur 8 mm, une largeur de 8mm et une épaisseur de 2 mm, et l'aimant 22 a une longueur de 20 mm, une largeur de 8 mm et une épaisseur de 2 mm.  According to the invention, for each branch, the hinge 20 comprises two connecting elements 21, 22; in the examples shown, the two connecting elements are magnetic elements, more precisely Neodymium-type magnets of generally parallelepipedal and substantially flat shape. In an indicative example, the magnet 21 has a length of 8 mm, a width of 8 mm and a thickness of 2 mm, and the magnet 22 has a length of 20 mm, a width of 8 mm and a thickness of 2 mm.
Les faces principales, c'est-à-dire les faces de plus grande surface, des aimants forment leurs pôles de sorte que la force d'attraction magnétique exercée par chaque aimant est perpendiculaire à ses faces principales. Sur l'aimant 22, une arête entre la zone de contact maximale (une face principale) et une zone de contact minimal (un bord latéral de l'aimant) forme un axe de pivotement de la branche lorsqu'elle passe de la position fermée à la position ouverte, la dite arête est arrondie pour faciliter le pivotement.  The main faces, that is to say the faces of larger area, magnets form their poles so that the magnetic attraction force exerted by each magnet is perpendicular to its main faces. On the magnet 22, an edge between the maximum contact area (a main face) and a minimum contact area (a side edge of the magnet) forms a pivot axis of the branch as it moves from the closed position in the open position, said edge is rounded to facilitate pivoting.
Le premier élément de liaison 21 est fixé, dans l'exemple par collage, dans une rainure interne 15a du tenon 15. Le premier élément de liaison 21 est positionné sensiblement perpendiculaire à la monture ; il crée ainsi une force magnétique sensiblement parallèle à la monture. L'épaisseur du premier élément de liaison 21 est inférieure à la profondeur de la rainure 15a de sorte que deux bords 15b, 15c de la rainure forment un moyen de guidage du deuxième élément de liaison lors d'un changement de position de la branche. La branche est ainsi guidée et maintenue la branche dans une position sensiblement perpendiculaire à la façade.  The first connecting element 21 is fixed, in the example by gluing, in an internal groove 15a of the post 15. The first connecting element 21 is positioned substantially perpendicular to the frame; it thus creates a magnetic force substantially parallel to the frame. The thickness of the first connecting element 21 is smaller than the depth of the groove 15a so that two edges 15b, 15c of the groove form a means for guiding the second connecting element during a change of position of the branch. The branch is thus guided and held the branch in a position substantially perpendicular to the facade.
Le deuxième élément de liaison (aimant) 22 est solidaire de la branche 12, 13, et s'étend selon un axe longitudinal de la dite branche. Plus précisément, dans les exemples représentés, le deuxième élément 22 est fixé à une extrémité de la branche dans une rainure 12a localisé à l'extrémité de la branche et s'étend en partie au delà de la branche. Les dimensions de la rainure 12a sont ici telles que l'aimant 22 affleure la face interne de la branche 12.The second connecting element (magnet) 22 is integral with the branch 12, 13, and extends along a longitudinal axis of said branch. More specifically, in the examples shown, the second element 22 is attached to one end of the branch in a groove 12a located at the end of the branch and extends partly beyond the branch. The dimensions of the groove 12a are here such that the magnet 22 is flush with the inner face of the branch 12.
En complément, dans le mode de réalisation représenté sur les figures 1 et 5, l'extrémité de la branche 12 est prolongée par deux plats 12b, 12c s'étendant dans le prolongement de la branche 12, de part et d'autre de l'aimant 22. Un bossage 12d, 12e est prévu sur une face interne de chacun des deux plats pour coopérer avec un évidement 15d, 15e correspondant du tenon 15. L'ensemble bossage + évidement forme un moyen de verrouillage de la branche sur le tenon en position ouverte. La branche reste démontable par une traction manuelle suffisamment forte pour sortir les bossages 12d, 12e des évidements 15d, 15e ; la souplesse et la faible épaisseur des matériaux le permet sans difficulté ; Pour éviter une fatigue des matériaux consécutive à des démontages de branches successifs, une gorge 15f peut être prévue en périphérie d'un évidement 15d, 15e pour faciliter le retrait du bossage 12d, 12e correspondant. In addition, in the embodiment shown in Figures 1 and 5, the end of the branch 12 is extended by two plates 12b, 12c extending in the extension of the branch 12, on either side of the magnet 22. A boss 12d, 12e is provided on an inner face of each of the two plates to cooperate with a recess 15d, 15e corresponding to the pin 15. The boss + recess assembly forms a locking means of the branch on the tenon in open position. The branch remains removable by manual pulling strong enough to remove the bosses 12d, 12e recesses 15d, 15e; the flexibility and the low thickness of the material allows it without difficulty; To avoid material fatigue following successive branches disassembly, a groove 15f may be provided at the periphery of a recess 15d, 15e to facilitate removal of the boss 12d, 12e corresponding.
Sur la figure 7, la lunette des figures 2-3 est représentée en position ouverte, stable : les deux éléments de liaison sont solidarisés par la force d'attraction magnétique des aimants ; une zone de contact (une face principale) du premier aimant 21 et une zone de contact maximale (correspondant à une partie d'une face principale) du deuxième aimant 22 sont en contact et forment ensemble un plan de joint à l'ouverture de surface maximale ; les pôles opposés des deux aimants étant collés l'un à l'autre et la surface de contact étant maximale, la force d'attraction magnétique qui solidarise les deux aimants est maximale et maintient les deux aimants solidaires.In Figure 7, the bezel of Figures 2-3 is shown in open position, stable: the two connecting elements are secured by the magnetic attraction force of the magnets; a contact zone (a main face) of the first magnet 21 and a maximum contact zone (corresponding to a portion of a main face) of the second magnet 22 are in contact and together form a joint plane at the surface opening maximum; the opposite poles of the two magnets being glued to each other and the contact surface being maximum, the magnetic attraction force which secures the two magnets is maximum and keeps the two magnets solid.
Dans une variante, l'élément de liaison 21 est un aimant et l'élément de liaison 22 est ferromagnétique mais non magnétique, par exemple un élément métallique. Dans ce cas, la force d'attraction du seul aimant 21 est suffisante pour solidariser les deux éléments de liaison avec une surface de contact maximale. In a variant, the connecting element 21 is a magnet and the connecting element 22 is ferromagnetic but non-magnetic, for example a metal element. In this case, the attraction force of the single magnet 21 is sufficient to secure the two connecting elements with a maximum contact surface.
Sur la figure 4, la lunette des fig. 2-3 est représentée en position fermée ; la zone de contact du premier aimant 21 et une zone de contact minimale (correspondant à un bord latéral) du deuxième aimant 22 sont en contact et forment ensemble à la fermeture un plan de joint de surface minimale ; la position fermée est instable car la force d'attraction magnétique entre les deux aimants est certes minimisée par rapport à la force correspondant à la position ouverte mais a tendance à attirer l'aimant 22 vers l'aimant 21 dans la position ouverte de la branche. Pour maintenir la position fermée, la façade optique de la lunette est positionnée au dessus des branches de sorte que le poids de la dite façade compense la force magnétique.  In FIG. 4, the telescope of FIGS. 2-3 is shown in closed position; the contact area of the first magnet 21 and a minimum contact area (corresponding to a side edge) of the second magnet 22 are in contact and together form at the closure a minimum surface joint plane; the closed position is unstable because the magnetic attraction force between the two magnets is certainly minimized relative to the force corresponding to the open position but tends to attract the magnet 22 to the magnet 21 in the open position of the branch . To maintain the closed position, the optical facade of the telescope is positioned above the branches so that the weight of the said facade compensates for the magnetic force.
La figure 6 montre une position intermédiaire des branches de la lunette des fig. 2-3. Les branches sont libérées, la force d'attraction magnétique F entre les aimants attirent chaque branche en position ouverte.  FIG. 6 shows an intermediate position of the branches of the telescope of FIGS. 2-3. The branches are released, the magnetic attraction force F between the magnets attract each branch in the open position.
La figure 5 montre une vue arrière de la lunette de la figure 1, avec moyen de verrouillage et avec une unique branche, la deuxième branche n'étant pas représentée. Figure 5 shows a rear view of the bezel of Figure 1, with locking means and with a single branch, the second branch is not shown.
