Description

L'invention a pour objet un dispositif anti-chocs pour mobile tournant sur un axe.The subject of the invention is a anti-shock device for mobile turning on a axis.

Les dispositifs anti-chocs traditionnels utilisés dans l'horlogerie présentent habituellement 5 parties : un support, le chaton, la pierre, le contre-pivot et un ressort, le ressort étant en appui contre le contre-pivot. Les cinq éléments mentionnés ci-dessus étant rassemblés dans le support, le ressort est de dimension réduite, et présente, en fonctionnement, une amplitude relativement peu importante. L'anti-chocs ainsi constitué est par conséquent d'une efficacité limitée. D'autre part, l'assemblage des pièces mentionnées ci-dessus, sur le dessus et le dessous du mobile, consiste en un dispositif relativement compliqué qui doit être complètement démonté lorsque l'on désire changer une pièce. Traditional anti-shock devices used in watchmaking usually exhibit 5 parts: a support, the kitten, the stone, the counter-pivot and a spring, the spring being support against the counter-pivot. The five elements mentioned above being collected in the support, the spring is of reduced size, and presents, in operation, an amplitude relatively unimportant. The anti-shock as well constituted is therefore effective limited. On the other hand, the assembly of parts mentioned above, above and below of the mobile, consists of a relatively complicated which must be completely disassembled when we want to change a room.

Le but de la présente invention est de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

Le dispositif anti-chocs pour mobile tournant sur un axe selon l'invention, est caractérisé en ce qu'il comprend au moins un élément ressort constitué d'une suite de lamelles reliant la périphérie de l'élément avec un support central agencé pour recevoir l'axe du mobile.The anti-shock device for rotating mobile on an axis according to the invention, is characterized in that that it comprises at least one spring element constituted a series of slats connecting the periphery of the element with a central support arranged for receive the axis of the mobile.

Les lamelles peuvent être radiales et agencées vers le centre du dispositif.The slats can be radial and arranged towards the center of the device.

Les lamelles peuvent également être inclinées de manière à former un angle aigu allant de 0 à 15 ° avec le diamètre du dispositif.Slats can also be tilted so as to form an acute angle ranging from 0 to 15 ° with the diameter of the device.

Les lamelles peuvent également présenter une configuration courbée. Elles se présenteront alors sous la forme d'un arc de cercle reliant la périphérie de l'élément ressort au support central.The slats may also have a curved configuration. They will then present themselves in the form of a circular arc connecting the periphery of the element spring to the central support.

Dans un mode d'exécution préféré, les lamelles viennent en prise avec une rainure pratiquée à la périphérie du support, un jeu étant prévu entre les lamelles et la rainure.In a preferred embodiment, the slats engage with a groove practiced at the periphery of the support, a game being provided between the slats and the groove.

Une pierre destinée à recevoir l'axe du mobile est chassée à l'intérieur du support.A stone intended to receive the axis of the mobile is driven inside the support.

Le dispositif comprend habituellement deux éléments ressort enfermant le mobile qui peut être un balancier spiral, le support étant alors réalisé d'une seule pièce avec le porte-piton du balancier.The device usually includes two spring elements enclosing the mobile which can be a balance spring, the support then being produced in one piece with the pendulum pin holder.

L'élément ressort peut présenter un secteur libre sans lamelle ressort.The spring element may have a sector free without spring strip.

L'invention a également pour objet un procédé de fabrication du dispositif, caractérisé en ce qu'il consiste en un usinage traditionnel par enlèvement de copeaux ou par découpage au fil (électroérosion à fil), par électroformage (électroérosion en plongée), par découpage à l'étampe, ou par des techniques de micro-moulages obtenus par illumination de résine sensibles aux rayons ultra-violets, ou encore par des méthodes de dépôts galvaniques dans des micro-moules, ou encore par traitement galvanique sur un support, le dispositif étant réalisé en métal ou en matière plastique, ou les deux ensemble.The invention also relates to a method manufacturing device, characterized in that it consists of a traditional machining by chip removal or wire cutting (wire EDM), by electroforming (plunge EDM), by cutting the stamp, or by micro-molding techniques obtained by illumination of resin sensitive to ultraviolet rays, or even by methods of galvanic deposits in micro-molds, or by galvanic treatment on a support, the device being made of metal or material plastic, or both.

L'élément ressort 1 représenté dans les figures 1 à 5 comprend une pierre 2 chassée dans un support 3, lui-même maintenu par une succession de lamelles 4 s'étendant radialement vers le centre 3 à partir d'une zone annulaire 5 de l'élément 1, qui se présente sous la forme d'un disque.The spring element 1 shown in the Figures 1 to 5 includes a stone 2 driven into a support 3, itself maintained by a succession of slats 4 extending radially towards the center 3 from an annular zone 5 of element 1, which is in the form of a disc.

Dans le mode d'exécution représenté dans le dessin, les lamelles s'étendent radialement vers le centre de l'élément. Cependant, selon une variante non représentée, les lamelles 4 peuvent présenter une courbure ou être inclinées de manière à former un angle aigu pouvant aller de 0 à 15° relativement au diamètre de l'élément. D'autre part, comme représenté dans la figure 2, les lamelles 4 deviennent plus minces à partir des 2/3 de leur longueur en direction du centre.In the embodiment represented in the drawing, the slats extend radially towards the center of the element. However, according to a variant not shown, the slats 4 may have a curvature or be inclined so as to form an acute angle which can range from 0 to 15 ° relatively the diameter of the element. On the other hand, as shown in Figure 2, the slats 4 become thinner from 2/3 of their length towards the center.

Les lamelles ressort 4 vont effectuer la fonction anti-chocs. Comme représenté dans la figure 3, la pierre 2, qui va permettre de guider les mobiles des mécanismes équipés des éléments ressort 1, est chassée à friction dans le support 3.The spring slats 4 will perform the anti-shock function. As shown in the Figure 3, stone 2, which will guide the mobiles of the mechanisms equipped with the elements spring 1, is frictionally driven into the support 3.

Le jeu en hauteur du mobile peut être réglé en chassant plus ou moins la pierre 2 dans le support 3. Le support 3 présente sur sa périphérie extérieure une rainure 6 destinée à recevoir les lamelles 4.The height of the mobile can be adjusted chasing more or less stone 2 in the support 3. Support 3 has on its periphery exterior a groove 6 intended to receive the slats 4.

La mise en place des lamelles ressort 4 est décrite en regard de la figure 4. Il suffit d'amener le support 3 contre les lamelles 4 et d'exercer une pression sur lesdites lamelles 4 jusqu'à ce qu'elles passent par-dessus le support 3 pour venir se loger dans la rainure 6. Dès que les lamelles sont en place dans la rainure 6, les lamelles ressort 4 reprennent leur position initiale, et l'élément 1 sa configuration plane. La figure 5 représentant la coupe A, à échelle agrandie, du support 3 contenant les lamelles 4 après que celles-ci aient repris leur position plane de repos, montre qu'il est prévu en hauteur un jeu 7 entre la rainure 6 et lesdites lamelles. De même, un jeu 8 de moindre importance est prévu latéralement entre lesdites lamelles 4 et le fond de le rainure 6. Les jeux 7 et 8 vont permettre à l'élément 1 d'avoir un fonctionnement libre et optimal.The installation of the spring slats 4 is described with reference to figure 4. It suffices bring the support 3 against the slats 4 and to exert pressure on said strips 4 until they pass over the support 3 to be housed in groove 6. As soon as the slats are in place in groove 6, the spring slats 4 return to their position initial, and element 1 its plane configuration. Figure 5 representing section A, to scale enlarged, of the support 3 containing the lamellae 4 after they have resumed their position rest plane, shows that it is provided in height a clearance 7 between the groove 6 and said strips. Similarly, a smaller game 8 is planned laterally between said slats 4 and the bottom of groove 6. Games 7 and 8 will allow element 1 to have free operation and optimal.

Il est possible de réaliser l'élément 1 par différents moyens connus à ce jour, comme l'usinage traditionnel par enlèvement de copeaux, ou par découpage au fil (électroérosion à fil), par électroformage (électroérosion en plongée), par découpage à l'étampe, ou par des techniques de micro-moulage obtenu par illumination de résine sensible aux rayons ultra-violets, ou par des méthodes de dépôts galvaniques dans les micro-moules, ou encore par traitement galvanique sur un support sans micro-moule.Element 1 can be made by different means known to date, such as machining traditional by chip removal, or by wire cutting (wire EDM), by electroforming (EDM), by stamping, or by techniques of micro-molding obtained by resin illumination sensitive to ultraviolet rays, or by galvanic deposition methods in micro-molds, or by galvanic treatment on a support without micro-mold.

Ce bloc de composants peut être réalisé en matières plastiques ou métalliques, ou les deux ensemble, ou par injection ou dépôt galvanique dans des micro-moules.This block of components can be made in plastic or metallic, or both together, or by injection or galvanic deposition in micro-molds.

La figure 6 représente un dispositif anti-chocs pour un balancier spiral 9 monté entre deux éléments ressort 1 et 1' des figures 1 à 5. Dans le cas où le balancier spiral 9 est monté comme représenté dans la figure 6, le porte-piton 10 permettant le réglage du balancier 9 est une partie intégrante du support 3, et le réglage peut être effectué à l'aide de le fente 11 pratiquée à la partie supérieure du support 3.Figure 6 shows an anti-shock device for a balance spring 9 mounted between two spring elements 1 and 1 'of FIGS. 1 to 5. In the case where the balance spring 9 is mounted as shown in Figure 6, the pin holder 10 allowing the adjustment of the pendulum 9 is a part integral with support 3, and the adjustment can be made using the slot 11 made at the upper part of the support 3.

En variante et pour permettre le réglage fin du dispositif, il est possible de laisser libre un secteur α de l'élément 1 ou 1' comme représenté dans la figure 7. Le porte-piton 10 sera alors plus accessible et le réglage sera ainsi facilité.Alternatively and to allow fine adjustment of the device, it is possible to leave free a sector α of element 1 or 1 'as shown in figure 7. The piton holder 10 will then be more accessible and adjustment will be facilitated.

En fonctionnement, le dispositif de la figure 6 peut absorber des chocs avec une amplitude beaucoup plus importante que les anti-chocs de l'art antérieur. Les éléments constitutifs du balancier sont ainsi mieux préservés. D'autre part, il est possible de prévoir l'interchangeabilité du balancier spiral à l'intérieur même du dispositif sans démonter ledit dispositif. En effet, comme montré dans la figure 8, il est possible avec un outil de soulever les lamelles ressort 4 dans le sens de la flèche 12, et d'extraire le balancier spiral 9 après avoir libéré son ressort dans le but de placer un autre balancier dans le dispositif sans démontage de l'ensemble.In operation, the device of the figure 6 can absorb shock with amplitude much more important than the bumpers of prior art. The constituent elements of pendulum are thus better preserved. On the other hand, it is possible to provide for the interchangeability of the balance spring inside the device without dismantling said device. Indeed, as shown in figure 8 it is possible with a tool to lift the spring slats 4 in the direction of arrow 12, and extract the pendulum hairspring 9 after releasing its spring for the purpose to place another balance in the device without dismantling the assembly.

Bien que le dispositif anti-chocs ait été développé pour l'horlogerie, son utilisation n'est cependant pas limitée à ce domaine, et le dispositif décrit peut être utilisé dans de nombreux domaines de la technique, notamment en mécanique, micro-mécanique, industrie spatiale, etc...Although the anti-shock device has been developed for watchmaking, its use is not however not limited to this area, and the described device can be used in many fields of technology, especially in mechanical, micro-mechanical, space industry, etc ...
