Description

La présente invention concerne un composant horloger destiné à être intégré dans une pièce d'horlogerie telle qu'une montre-bracelet ou une montre de poche. La présente invention concerne plus particulièrement un composant horloger destiné à être assemblé à une pièce, telle qu'un axe, par chassage.The present invention relates to a horological component intended to be integrated into a timepiece such as a wristwatch or a pocket watch. The present invention relates more particularly to a horological component intended to be assembled to a part, such as an axle, by driving.

Le chassage est une méthode d'assemblage par insertion à pression. Le maintien en position de composants assemblés de cette façon est garanti par les forces de frottement s'exerçant entre les surfaces de contact.Driving in is a snap-in assembly method. The maintenance in position of components assembled in this way is guaranteed by the frictional forces acting between the contact surfaces.

Les figures 6a, 6b, 6c et 6d montrent des structures de l'art antérieur utilisées pour le chassage.The figures 6a, 6b , 6c and 6d show structures of the prior art used for driving.

Traditionnellement, le chassage se fait par simple insertion à pression d'un axe 11 dans un composant 10 présentant un trou, comme illustré à la figure 6a. Cette technique engendre la formation de bavures. Il s'agit de parcelles de matière refoulée qui adhèrent plus ou moins fortement. Dans une fabrication soignée, les bavures ne doivent pas subsister; en effet, en se détachant, elles peuvent tomber sur des organes délicats et provoquer des arrêts ou d'autres perturbations du mécanisme.Traditionally, driving is done by simple insertion by pressure of a pin 11 in a component 10 having a hole, as illustrated in figure 6a . This technique causes the formation of burrs. These are particles of repressed material that adhere more or less strongly. In a careful manufacture, the burrs must not remain; in fact, by detaching themselves, they can fall on delicate organs and cause stoppages or other disturbances of the mechanism.

Pour atténuer ces bavures, des alvéoles 22, visant à diminuer l'interaction entre le composant 20 présentant un trou et l'axe 21 qu'il reçoit, peuvent être ménagées dans la surface intérieure du trou, comme illustré à la figure 6b. Cependant, cela ne permet pas d'éliminer les bavures.To attenuate these burrs, cells 22, aimed at reducing the interaction between the component 20 having a hole and the pin 21 which it receives, can be made in the inner surface of the hole, as illustrated in FIG. figure 6b . However, this does not remove the burrs.

La thèse « Vers la maîtrise de la qualité des assemblages de précision » de F. Bourgeois, Ecole Polytechnique Fédérale de Lausanne, Suisse, 2007 , décrit un composant 30 tel que représenté à la figure 6c comprenant un trou 31 destiné à recevoir un axe par chassage. Comme illustré à la figure 6c, le trou 31 recevant l'axe est bordé de cannelures 33 visant à faire varier la rigidité en diminuant les surfaces de contact entre le composant 30 et le reste de la surface intérieure du trou 31. Ce composant 30 comprend également des évidements 32 en forme de bananes derrière les cannelures 33 pour augmenter l'élasticité de la partie du composant autour du trou 31. Un tel composant 30 ne semble cependant pas satisfaisant et devrait entraîner la formation de bavures de par la présence d'arêtes aux points de jonction entre les cannelures 33 et le reste de la surface intérieure du trou 31.The thesis “Towards controlling the quality of precision assemblies” by F. Bourgeois, Ecole Polytechnique Fédérale de Lausanne, Switzerland, 2007 , describes a component 30 as shown in figure 6c comprising a hole 31 intended to receive an axis by driving. As shown in figure 6c , the hole 31 receiving the axis is bordered by grooves 33 aiming to vary the rigidity by reducing the contact surfaces between the component 30 and the rest of the inner surface of the hole 31. This component 30 also comprises shaped recesses 32. of bananas behind the grooves 33 to increase the elasticity of the part of the component around the hole 31. Such a component 30 does not appear to be satisfactory, however, and should lead to the formation of burrs due to the presence of ridges at the junction points between the grooves 33 and the rest of the inner surface of hole 31.

Afin d'éviter tout phénomène de déformation plastique, il a également été proposé dans la demande de brevet européen EP1708045 de la présente demanderesse de border la surface intérieure du trou de bras élastiques 42 ne subissant qu'une déformation élastique lors du chassage de l'axe 41 dans le composant 40 présentant un trou, comme illustré à la figure 6d. Bien qu'évitant les bavures, ce type de structure n'est pas pleinement satisfaisant car il ne permet d'obtenir qu'une faible tenueIn order to avoid any plastic deformation phenomenon, it has also been proposed in the European patent application EP1708045 of the present applicant to border the inner surface of the hole of elastic arms 42 only undergoing elastic deformation when driving the pin 41 into the component 40 having a hole, as illustrated in figure 6d . Although avoiding burrs, this type of structure is not fully satisfactory because it only allows a low resistance to be obtained.

Il existe encore les documents EP1513029A1 et EP2755093A2 qui divulguent des viroles élastiques pour assurer un serrage élastique, ou les documents EP2595005 A1 et WO2012/084382A2 qui divulguent des systèmes d'assemblages pouvant se déformer plastiquement et/ou élastiquement.There are still documents EP1513029A1 and EP2755093A2 which disclose elastic collars to provide elastic clamping, or documents EP2595005 A1 and WO2012 / 084382A2 which disclose assembly systems which can be deformed plastically and / or elastically.

Le but de la présente invention est de fournir un composant horloger destiné à être assemblé à une pièce par chassage qui permette une bonne tenue tout en diminuant voire en annulant la formation de bavures.The aim of the present invention is to provide a watch component intended to be assembled to a part by driving in which allows good hold while reducing or even eliminating the formation of burrs.

L'invention propose à cette fin un composant horloger comprenant une ouverture traversante de centre O dont le contour est fermé et au moins une lumière autour de l'ouverture, l'ouverture et l'au moins une lumière définissant entre elles une paroi dont la surface interne définit ledit contour fermé, la paroi étant rattachée au reste du composant par au moins une zone de liaison, la paroi étant apte à se déformer radialement élastiquement et plastiquement lorsqu'on chasse une partie à section circulaire d'une pièce dans l'ouverture, ladite surface interne comprenant une encoche en face de la ou chacune des zones de liaison et au moins une portion en arc de cercle de centre O intercalée avec l'au moins une encoche, caractérisé en ce que la ou chaque encoche a un fond et deux parties de liaison, chaque partie de liaison reliant le fond à une extrémité de l'au moins une portion en arc de cercle en étant tangente à la portion en arc de cercle correspondante au point de jonction avec cette dernière et ayant en tout point un rayon de courbure plus grand que celui de l'au moins une portion en arc de cercle.The invention provides for this purpose a horological component comprising a through opening of center O, the outline of which is closed and at least one lumen around the opening, the opening and the at least one lumen defining between them a wall of which the internal surface defines said closed contour, the wall being attached to the rest of the component by at least one connecting zone, the wall being able to deform radially elastically and plastically when a part with a circular section of a part is driven out in the opening, said internal surface comprising a notch in front of the or each of the connecting zones and at least one portion in an arc of a center O interspersed with the at least one notch, characterized in that the or each notch has a bottom and two connecting parts, each connecting part connecting the bottom to one end of the at least one circular arc portion being tangent to the corresponding circular arc portion at the junction point with this d last and having at all points a radius of curvature greater than that of the at least one portion in the form of an arc of a circle.

L'invention propose également un ensemble comprenant un tel composant horloger et une pièce comprenant une partie à section circulaire, ladite partie à section circulaire étant chassée dans l'ouverture du composant horloger.The invention also proposes an assembly comprising such a timepiece component and a part comprising a part with a circular section, said part with a circular section being driven into the opening of the timepiece component.

L'invention propose également une pièce d'horlogerie telle qu'une montre-bracelet ou une montre de poche comprenant un tel ensemble.The invention also proposes a timepiece such as a wristwatch or a pocket watch comprising such an assembly.

Le composant horloger selon l'invention est apte à être assemblé par chassage avec une bonne tenue et sans création de bavure à une pièce comprenant une partie à section circulaire.The watch component according to the invention is able to be assembled by driving in with good hold and without creating a burr to a part comprising a part with a circular section.

En référence à la figure 1, un composant horloger 1 selon l'invention comprend une ouverture 2 traversante de centre O dont le contour est fermé et deux lumières 3 uniformément réparties autour de l'ouverture 2 définissant entre elles deux zones de liaison 4 situées sur un cercle c concentrique avec l'ouverture 2.With reference to the figure 1 , a watch component 1 according to the invention comprises a through opening 2 with center O whose contour is closed and two openings 3 uniformly distributed around the opening 2 defining between them two connecting zones 4 located on a circle c concentric with the opening 2.

L'ouverture 2 est destinée à recevoir un axe et est apte à se déformer radialement élastiquement et plastiquement lorsqu'on y chasse ledit axe. L'ouverture 2 et les lumières 3 définissent entre elles une paroi cylindrique 6 qui est rattachée au reste du composant par les zones de liaison 4. La paroi cylindrique 6 présente du fait de sa faible épaisseur une certaine élasticité ce qui lui permet de se déformer d'abord radialement élastiquement, de manière suffisante, puis radialement plastiquement lors du chassage de l'axe dans l'ouverture 2. En pratique, la paroi cylindrique 6 gonfle et se déforme beaucoup lors du chassage de l'axe, offrant ainsi une bonne tenue du composant horloger 1 sur ledit axe.The opening 2 is intended to receive an axis and is capable of deforming radially elastically and plastically when said axis is driven therein. The opening 2 and the slots 3 define between them a cylindrical wall 6 which is attached to the rest of the component by the connecting zones 4. The cylindrical wall 6 has, due to its small thickness, a certain elasticity which allows it to deform. first radially elastically, sufficiently, then radially plastically when driving the pin into the opening 2. In practice, the cylindrical wall 6 swells and deforms a lot when the pin is driven out, thus offering good holding of the watch component 1 on said axis.

Dans le mode de réalisation représenté à la figure 1, les lumières 3 ont chacune un contour fermé. Elles sont oblongues, s'étendent le long du cercle c et ont typiquement la même forme et les mêmes dimensions. L'ensemble constitué de l'ouverture 2 et des lumières 3 représenté à la figure 1 comprend deux axes de symétrie S1, S2. En variante, les lumières 3 peuvent être à contour ouvert, de préférence presque complètement fermé, et/ou être de formes ou de dimensions différentes.In the embodiment shown in figure 1 , the lights 3 each have a closed contour. They are oblong, extend along the circle c, and typically have the same shape and dimensions. The set made up opening 2 and lights 3 shown in figure 1 includes two axes of symmetry S 1 , S 2 . As a variant, the slots 3 may have an open contour, preferably almost completely closed, and / or be of different shapes or sizes.

Le composant horloger 1 est typiquement réalisé en un matériau métallique (métal ou alliage) tel que le nickel ou nickel-phosphore, l'acier, le cuivre, le béryllium, le laiton, l'aluminium, le titane, l'or, le platine ou un alliage de cuivre, nickel et zinc tel que le maillechort mais il peut également être réalisé en tout autre matériau possédant un domaine de déformation élastique et un domaine de déformation plastique.The watch component 1 is typically made of a metallic material (metal or alloy) such as nickel or nickel-phosphorus, steel, copper, beryllium, brass, aluminum, titanium, gold, platinum or an alloy of copper, nickel and zinc such as nickel silver, but it can also be made from any other material having an elastic deformation domain and a plastic deformation domain.

La surface interne de l'ouverture 2 du composant horloger 1 représenté à la figure 1 comprend une encoche 5 en face de chacune des zones de liaison 4 ainsi que des portions en arc de cercle 2a de centre O intercalées entre les encoches 5 et s'étendant chacune sur un angle d'environ 115°.The internal surface of the opening 2 of the watch component 1 shown in figure 1 comprises a notch 5 opposite each of the connecting zones 4 as well as circular arc portions 2a of center O interposed between the notches 5 and each extending over an angle of approximately 115 °.

Lors du chassage de l'axe dans l'ouverture 2, en l'absence des encoches 5 les zones de liaison 4 seraient soumises à de fortes contraintes car elles ne peuvent pas se déformer radialement. Chaque encoche 5 a pour but de diminuer les contraintes au niveau de la zone de liaison 4 à laquelle elle fait face, atténuant ainsi la formation de bavures.When driving the pin into the opening 2, in the absence of the notches 5, the connecting zones 4 would be subjected to strong stresses because they cannot deform radially. The purpose of each notch 5 is to reduce the stresses at the level of the connection zone 4 to which it faces, thus reducing the formation of burrs.

Les portions en arc de cercle 2a peuvent s'étendre sur un angle différent de 115°, cet angle étant toutefois typiquement d'au moins 15°, de préférence d'au moins 25°, de préférence d'au moins 35°, de préférence d'au moins 45°, de préférence d'au moins 55°, de préférence d'au moins 65°, de préférence d'au moins 75°, de préférence d'au moins 85°, de préférence d'au moins 95°, de préférence d'au moins 105°, de préférence encore d'au moins 115°. L'angle sur lequel s'étendent les portions en arc de cercle 2a doit en effet être suffisant pour assurer un bon maintien de l'axe à chasser à l'intérieur de l'ouverture 2 et pour éviter des zones de contact trop étroites entre l'axe et la surface interne de l'ouverture 2, en particulier des contacts ponctuels qui entraînent la formation de bavures lors du chassage. De préférence, chaque portion en arc de cercle 2a s'étend d'une extrémité d'une encoche 5 à une extrémité de l'autre encoche 5.The arcuate portions 2a may extend over an angle other than 115 °, this angle being however typically at least 15 °, preferably at least 25 °, preferably at least 35 °, of preferably at least 45 °, preferably at least 55 °, preferably at least 65 °, preferably at least 75 °, preferably at least 85 °, preferably at least 95 °, preferably at least 105 °, more preferably at least 115 °. The angle over which the arcuate portions 2a extend must in fact be sufficient to ensure good retention of the axis to be driven out inside the opening 2 and to avoid excessively narrow contact zones between the axis and the internal surface of the opening 2, in particular point contacts which lead to the formation of burrs when driving out. Preferably, each arcuate portion 2a extends from one end of a notch 5 to one end of the other notch 5.

Chaque encoche 5 a un fond 5a et deux parties de liaison 5b reliant ce fond 5a aux deux portions en arc de cercle 2a qui l'entourent.Each notch 5 has a bottom 5a and two connecting parts 5b connecting this bottom 5a to the two circular arc portions 2a which surround it.

Ce fond 5a est avantageusement en arc de cercle de rayon de courbure plus petit que celui des portions en arc de cercle 2a.This bottom 5a is advantageously in an arc of a circle with a radius of curvature smaller than that of the portions in an arc of a circle 2a.

Chaque partie de liaison 5b est tangente à la portion en arc de cercle 2a correspondante au point de jonction avec cette dernière et a, en tout point, un rayon de courbure plus grand que celui des portions en arc de cercle 2a. Cela évite la création d'arêtes ou de reliefs, bosses ou creux, de faibles rayons de courbure qui entraînent la formation de bavures lors du chassage de l'axe. Les parties de liaison 5b peuvent, par exemple, être constituées de droites auquel cas elles présentent un rayon de courbure infini, ou de courbes, typiquement d'arcs de cercle, présentant une convexité inversée par rapport à celle des portions en arc de cercle 2a.Each connecting part 5b is tangent to the arcuate portion 2a corresponding to the junction point with the latter and has, at all points, a radius of curvature greater than that of the arcuate portions 2a. This prevents the creation of edges or reliefs, bumps or hollows, small radii of curvature which lead to the formation of burrs when driving out the axle. The connecting parts 5b can, for example, consist of straight lines in which case they have an infinite radius of curvature, or of curves, typically of arcs of a circle, having an inverted convexity with respect to that of the arc portions 2a. .

Chaque partie de liaison 5b est de préférence également tangente au fond 5a au point de jonction avec ce dernier.Each connecting part 5b is preferably also tangent to the bottom 5a at the point of junction with the latter.

La distance radiale entre chaque portion en arc de cercle 2a et la lumière 3 lui faisant face (épaisseur de la paroi cylindrique 6) est de préférence égale à au moins 5%, de préférence à au moins 10%, de préférence à au moins 15%, de préférence à au moins 20%, de préférence à au moins 25%, de préférence encore à au moins 30%, du rayon des portions en arc de cercle 2a. Elle est en outre de préférence égale à au plus 50%, de préférence à au plus 45%, de préférence à au plus 40%, de préférence encore à au plus 35%, du rayon des portions en arc de cercle 2a. De telles proportions permettent d'assurer une élasticité contrôlée de la paroi cylindrique 6 pour qu'elle puisse se déformer élastiquement puis plastiquement lors du chassage d'un axe de rayon supérieur au rayon des portions en arc de cercle 2a dans l'ouverture 2 de manière à assurer une tenue suffisante de l'axe dans l'ouverture 2 sans provoquer de bavures lors de son insertion.The radial distance between each arcuate portion 2a and the slot 3 facing it (thickness of the cylindrical wall 6) is preferably equal to at least 5%, preferably at least 10%, preferably at least 15 %, preferably at least 20%, preferably at least 25%, more preferably at least 30%, of the radius of the circular arc portions 2a. It is furthermore preferably equal to at most 50%, preferably at most 45%, preferably at most 40%, more preferably at most 35%, of the radius of the arcuate portions 2a. Such proportions make it possible to ensure a controlled elasticity of the cylindrical wall 6 so that it can deform elastically and then plastically when driving out an axis with a radius greater than the radius of the arcuate portions 2a in the opening 2 of so as to ensure a sufficient of the axis in the opening 2 without causing burrs during its insertion.

En variante, le composant horloger selon l'invention peut comprendre plus de deux lumières 3. Il peut typiquement en comprendre trois, comme illustré à la figure 2, quatre, comme illustré à la figure 3, ou plus.As a variant, the horological component according to the invention can comprise more than two lights 3. It can typically include three, as illustrated in figure 2 , four, as shown in figure 3 , or more.

Toutefois, le nombre de lumières 3 est de préférence au plus égal à quatre pour permettre aux portions en arc de cercle 2a d'avoir la plus grande étendue possible.However, the number of lights 3 is preferably at most equal to four to allow the arcuate portions 2a to have the greatest possible extent.

Les composants horlogers selon des variantes comprenant plus de deux lumières 3 se distinguent également du composant horloger 1 comprenant deux lumières 3 décrit ci-avant par leur nombre de zones de liaison 4, d'encoches 5 et d'axes de symétrie S1, S2, S3, S4.The watch components according to variants comprising more than two lights 3 are also distinguished from the watch component 1 comprising two lights 3 described above by their number of connection zones 4, notches 5 and axes of symmetry S 1 , S 2 , S 3 , S 4 .

Dans d'autres variantes, le composant horloger 1 selon l'invention peut ne comprendre qu'une lumière 3 s'étendant sur un cercle c' concentrique avec l'ouverture 2, comme illustré à la figure 4. Dans ce cas, le composant 1 comprend typiquement une zone de liaison 4 placée sur le cercle c' concentrique avec l'ouverture 2, entre les extrémités de cette lumière 3, et une encoche 5 faisant face à la zone de liaison 4. Dans l'exemple de la figure 4, la lumière 3 a un contour complètement fermé.In other variants, the horological component 1 according to the invention may only comprise a slot 3 extending over a circle c 'concentric with the opening 2, as illustrated in figure 4 . In this case, component 1 typically comprises a connection zone 4 placed on the circle c 'concentric with the opening 2, between the ends of this slot 3, and a notch 5 facing the connection zone 4. In the example of the figure 4 , light 3 has a completely closed contour.

Chaque encoche 5 est de préférence centrée par rapport à la zone de liaison 4 à laquelle elle fait face.Each notch 5 is preferably centered with respect to the connecting zone 4 to which it faces.

Quelle que soit la variante, l'ensemble constitué de l'ouverture 2 et de la ou des lumières 3 du composant horloger 1 selon l'invention comprend typiquement autant d'axe(s) de symétrie S1, S2, S3, S4 que d'encoche(s) 5.Whatever the variant, the assembly consisting of the opening 2 and of the slot (s) 3 of the watch component 1 according to the invention typically comprises as many axis (s) of symmetry S 1 , S 2 , S 3 , S 4 as notch (s) 5.

Les zones de liaison 4 sont des zones de contraintes maximales. Les lumières 3 sont donc avantageusement conçues pour les rendre les plus étroites possible.The connection zones 4 are zones of maximum stress. The lights 3 are therefore advantageously designed to make them as narrow as possible.

Le composant horloger 1 selon l'invention peut être fabriqué à l'aide de techniques d'usinage conventionnelles, typiquement par croissance LIGA (lithographie, galvanoplastie, moulage), par fraisage, par électroérosion, par des techniques de découpe laser, ou par impression 3D.The watch component 1 according to the invention can be manufactured using conventional machining techniques, typically by LIGA growth. (lithography, electroplating, molding), by milling, by electroerosion, by laser cutting techniques, or by 3D printing.

Le composant horloger 1 ainsi obtenu est apte à recevoir un axe par chassage dans son ouverture 2 et permet la réalisation d'un assemblage présentant un bon maintien et n'engendrant pas la formation de bavures.The watch component 1 thus obtained is able to receive an axis by driving it into its opening 2 and allows the production of an assembly having good retention and not causing the formation of burrs.

Il apparaît clairement à l'homme du métier que la présente invention n'est en aucun cas limitée aux modes de réalisation présentés ci-dessus et illustrés aux figures.It is clear to those skilled in the art that the present invention is in no way limited to the embodiments presented above and illustrated in the figures.

En effet, il est évident que l'on pourrait appliquer l'invention pour chasser une autre pièce qu'un axe dans l'ouverture 2 du composant horloger 1, pour autant que cette pièce comprenne au moins une partie à section circulaire, par exemple cylindrique ou conique. Cette pièce peut être par exemple un piton pour la fixation de l'extrémité extérieure d'un spiral, cette extrémité extérieure comprenant l'ouverture 2 et les lumières 3.Indeed, it is obvious that the invention could be applied to drive out a part other than an axis in the opening 2 of the watch component 1, provided that this part comprises at least one part with a circular section, for example. cylindrical or conical. This part may for example be a eyebolt for fixing the outer end of a hairspring, this outer end comprising the opening 2 and the slots 3.

La figure 5a illustre une roue d'échappement comprenant deux lumières 3 à contours fermés, selon la variante de l'invention représentée à la figure 1. La figure 5b illustre, quant à elle, une aiguille d'horlogerie comprenant une unique lumière 3 à contour ouvert. Le composant 1 selon l'invention pourrait également être par exemple une bascule, une roue d'engrenage, un pignon, une virole, un spiral, un pont, une platine ou tout autre composant horloger destiné à recevoir une partie à section circulaire d'une pièce, axe ou autre, par chassage.The figure 5a illustrates an escape wheel comprising two openings 3 with closed contours, according to the variant of the invention shown in figure 1 . The figure 5b illustrates, for its part, a clockwork hand comprising a single lumen 3 with an open contour. The component 1 according to the invention could also be, for example, a lever, a gear wheel, a pinion, a ferrule, a balance spring, a bridge, a plate or any other watch component intended to receive a part with a circular section of a part, axis or other, by driving.

Le composant horloger 1 selon l'invention est typiquement utilisé dans une pièce d'horlogerie telle qu'une montre-bracelet ou une montre de poche.The horological component 1 according to the invention is typically used in a timepiece such as a wristwatch or a pocket watch.
