L'invention concerne un élément sécable 10 d'oscillateur d'horlogerie.The invention relates to a breakable watch oscillator element.

Cet élément sécable 10 est conçu pour protéger, pendant la fabrication, la manutention, l'assemblage, les éléments les plus fragiles d'au moins un composant horloger 1.This breakable element 10 is designed to protect, during manufacture, handling, assembly, the most fragile elements of at least one watch component 1.

L'élément sécable 10 est conçu pour être séparé, après son assemblage avec d'autres éléments, en une partie fonctionnelle constituée par chaque composant 1 qu'il comporte, et une partie sacrificielle qui n'a plus d'utilité au sein du mécanisme horloger au sein duquel est incorporé le composant 1. Cette partie sacrificielle est conçue pour une manutention aisée, par un opérateur ou par un moyen de manutention automatisé, et elle constitue un élément de protection 4, qui protège chaque composant 1, et en particulier les éléments les plus fragiles que renferme ce dernier, jusqu'à la désolidarisation de l'élément de protection 4 et des composants 1, par rupture par flexion et/ou torsion, découpe avec un outil tel que pince coupante ou scie, ou découpe au laser, ou autre.The breakable element 10 is designed to be separated, after its assembly with other elements, into a functional part constituted by each component 1 that it comprises, and a sacrificial part which has no more use within the mechanism This sacrificial portion is designed for easy handling, by an operator or by an automated handling means, and constitutes a protection element 4, which protects each component 1, and in particular the the most fragile elements contained in the latter, until the separation of the protective element 4 and the components 1, by bending and / or torsion fracture, cutting with a tool such as a cutting or sawing pliers, or laser cutting , Or other.

L'élément sécable 10 est encore conçu, dans une variante particulière décrite plus loin, pour autoriser la mise sous précontrainte d'un élément flexible que comporte le composant 1, pendant l'élaboration de cet élément sécable 10, et pour conserver la position de précontrainte pendant tout l'assemblage du composant 1, ce qui rend inutile toute contrainte par un outillage de conformation ou similaire.The breakable element 10 is further designed, in a particular variant described below, to allow the prestressing of a flexible element that comprises the component 1, during the development of this breakable element 10, and to maintain the position of prestressing throughout the assembly of the component 1, which makes unnecessary any constraint by conformation tooling or the like.

Dans une application préférée mais non limitative de l'invention, l'élément fragile à protéger est un élément flexible, tel qu'une lame ou un ressort, ou similaire.In a preferred but non-limiting application of the invention, the fragile element to be protected is a flexible element, such as a blade or a spring, or the like.

Plus particulièrement, l'élément sécable 10 comporte ainsi au moins un composant 1, lequel comporte au moins une lame flexible 2 ou au moins une lame à cols 20.More particularly, the breakable element 10 thus comprises at least one component 1, which comprises at least one flexible blade 2 or at least one collar blade 20.

Cette lame flexible 2 ou lame à cols 20, joint deux blocs 3, chacun plus rigide que la lame flexible 2 ou la lame à cols 20 concernée, au niveau d'encastrements pour la lame flexible 2, ou au niveau de cols 21 pour la lame à cols 20.This flexible blade 2 or collar blade 20, joins two blocks 3, each more rigid than the flexible blade 2 or the collar blade 20 concerned, at the level of embedding for the flexible blade 2, or at the neck 21 for the collar blade 20.

Selon l'invention, l'élément sécable 10 comporte au moins un élément de protection 4, qui est contigu à au moins un tel bloc 3, auquel l'élément de protection 4 est relié par au moins une liaison sécable 5. Cette liaison sécable 5 est agencée pour permettre le détachement de l'élément de protection 4 d'avec le composant 1, quand ce composant 1 est fixé, par l'intermédiaire au moins du bloc 3 particulier qui est contigu à l'élément de protection 4, à un élément externe 9, lequel est plus rigide que la lame flexible 2 ou que les cols de la lame à cols 20.According to the invention, the breakable element 10 comprises at least one protection element 4, which is contiguous with at least one such block 3, to which the protection element 4 is connected by at least one breakable connection 5. This breakable connection 5 is arranged to allow the detachment of the protection element 4 from the component 1, when this component 1 is attached, through at least the particular block 3 which is contiguous with the protection element 4, to an outer member 9, which is more rigid than the flexible blade 2 or the collars of the blade with collar 20.

Les figures illustrent, de façon non limitative, des lames flexibles 2 droites, des lame à cols 20 avec un col 21 de part et d'autre, ou encore une lame flexible 2 comportant un oeil 25 en sa partie médiane, on comprend que les formes de ces éléments fragiles peuvent être extrêmement diverses.The figures illustrate, in a nonlimiting manner, flexible strips 2 straight, necked blade 20 with a neck 21 on either side, or a flexible blade 2 having an eye 25 in its middle part, it is understood that the forms of these fragile elements can be extremely diverse.

De façon particulière, le composant 1 est un composant d'oscillateur d'horlogerie, et la lame flexible 2, ou la lame à cols 20, est un composant important de l'oscillateur, et en assure les propriétés chronométriques.In particular, the component 1 is a clock oscillator component, and the flexible blade 2, or the collar blade 20, is an important component of the oscillator, and ensures the chronometric properties.

La liaison sécable 5 peut être réalisée de différentes façons. Sur les figures 1, 2, 5, 6 cette liaison sécable 5 comporte une zone de section plus faible que celle du bloc 3 et que celle de l'élément de protection 4 qui lui sont adjacents, à la façon d'une plaque de chocolat, ou profil 2D, la liaison sécable 5 est facile à rompre par flexion. Sur les figures 7 et 9 à 14, la liaison sécable 5 comporte au moins un pont 7, ou plusieurs ponts 7 qui peuvent notamment être séparés par des ouvertures traversantes 8 tels que lumières ou perçages tel que visible sur la figure 7, ou encore des ponts minces disjoints comme sur les figures 9 à 14. La liaison sécable 5 peut encore comporter au moins une amorce de rupture réalisée dans l'épaisseur de la matière, tel que visible sur la figure 8, et convient en particulier au cas de l'élaboration par un procédé multi-couches de l'élément sécable 10, lors duquel des chambres sont ménagées dans l'épaisseur du matériau. Naturellement, la liaison sécable 5 peut être réalisée par panachage de ces différents modes d'élaboration, et peut comporter une zone de section plus faible que celle du bloc 3 et de l'élément de protection 4 qui lui sont adjacents, et/ou comporter un ou plusieurs ponts 7 séparés ou non par des ouvertures traversantes 8, et/ou comporter au moins une amorce de rupture réalisée dans l'épaisseur de la matière. De façon avantageuse lors de l'emploi de ponts 7, ceux-ci sont conçus pour être très facilement rompus par torsion et/ou flexion et/ou par découpe.The breakable connection 5 can be realized in different ways. On the Figures 1, 2 , 5, 6 this breakable connection 5 has a zone of smaller section than that of the block 3 and that of the protective element 4 which are adjacent to it, in the manner of a chocolate plate, or 2D profile, the breakable connection 5 is easy to break bending. On the figures 7 and 9 to 14 , the breakable connection 5 comprises at least one bridge 7, or several bridges 7 which can in particular be separated by through openings 8 such as lights or holes as visible on the figure 7 , or thin bridges disjointed as on the Figures 9 to 14 . The breakable connection 5 may also comprise at least one rupture primer made in the thickness of the material, as visible on the figure 8 , and is particularly suitable in the case of the development by a multi-layer method of the breakable element 10, in which chambers are formed in the thickness of the material. Naturally, the breakable connection 5 can be made by mixing these different methods of production, and may comprise a zone of smaller section than that of the block 3 and the protective element 4 which are adjacent to it, and / or comprise one or more bridges 7 separated or not by through openings 8, and / or comprise at least one breaking primer made in the thickness of the material. Advantageously when using bridges 7, they are designed to be very easily broken by torsion and / or bending and / or cutting.

Dans une réalisation particulière avantageuse, et tel que visible sur les figures, un même élément de protection 4 est contigu aux blocs 3 situés de part et d'autre d'une même lame flexible 2 ou lame à cols 20, de manière à protéger cette lame flexible 2 ou lame à cols 20.In a particular advantageous embodiment, and as visible in the figures, a same protective element 4 is contiguous with the blocks 3 situated on either side of the same flexible blade 2 or collar blade 20, so as to protect this flexible blade 2 or collar blade 20.

Plus particulièrement, chaque bloc 3 est contigu à un élément de protection 4 auquel il est relié par une liaison sécable 5.More particularly, each block 3 is contiguous to a protection element 4 to which it is connected by a breakable connection 5.

Dans une réalisation particulière, au moins un dit bloc 3 forme une masse inertielle libre, et est agencé pour être fixé à une autre masse inertielle libre d'un autre élément sécable 10, ou à un élément externe 9; c'est par exemple le cas de la figure 14 dont le secteur annulaire est une telle masse inertielle.In a particular embodiment, at least one said block 3 forms a free inertial mass, and is arranged to be fixed to another free inertial mass of another breakable element 10, or to an external element 9; this is for example the case of figure 14 whose annular sector is such an inertial mass.

Au moins un bloc 3 comporte au moins une surface d'assemblage 6 ou 11 pour sa fixation rigide à au moins un élément externe 9. Les figures distinguent des surfaces d'assemblage 6 lisses, telles que des alésages ou similaires, et des logements traversants 11 comportant un relief apte à assurer un serrage : plus particulièrement, et tel que visible sur la figure 5, un logement traversant 11 comporte, pour le passage et la fixation d'une broche ou d'une goupille ou d'une vis ou similaire, une pluralité de ressorts élastiques de centrage 12 et une pluralité de butées de limitation de course radiale 13. Naturellement les surfaces d'appui supérieure et inférieure de l'élément sécable 10 sont, surtout dans la réalisation préférée et illustrée par les figures où l'élément sécable 10 s'étend entre deux surfaces supérieure et inférieure parallèles, aussi des surfaces d'assemblage avec des éléments externes 9. La figure 2 montre ainsi une structure horlogère 100, notamment une structure d'oscillateur, comportant un empilement d'éléments sécables 10 et d'éléments externes 9, qui sont maintenus les uns par rapport aux autres, dans la direction de l'empilement, par d'autres éléments externes 9 qui sont des éléments de liaison et/ou de fixation : tiges, boulons, vis, rivets, goupilles, ou similaires.At least one block 3 comprises at least one assembly surface 6 or 11 for its rigid attachment to at least one external element 9. The figures distinguish smooth assembly surfaces 6, such as bores or the like, and through housings 11 having a relief capable of ensuring a tightening: more particularly, and as visible on the figure 5 a traversing housing 11 comprises, for the passage and fixing of a pin or a pin or a screw or the like, a plurality of resilient centering springs 12 and a plurality of radial stroke limiting stops 13. Naturally the upper and lower bearing surfaces of the breakable element 10 are, especially in the preferred embodiment and illustrated by the figures where the breakable element 10 extends between two parallel upper and lower surfaces, also assembly surfaces with external elements 9. The figure 2 thus shows a watch structure 100, in particular an oscillator structure, comprising a stack of breakable elements 10 and external elements 9, which are held relative to each other, in the direction of the stack, by means of FIG. other external elements 9 which are connecting and / or fastening elements: rods, bolts, screws, rivets, pins, or the like.

Plus particulièrement, chaque bloc 3 comporte au moins une telle surface d'assemblage 6 ou 11 pour sa fixation rigide à au moins un élément externe 9.More particularly, each block 3 comprises at least one such assembly surface 6 or 11 for its rigid attachment to at least one external element 9.

Plus particulièrement, au moins un dit bloc 3 forme une masse inertielle libre et est dépourvu de liaison avec un élément externe 9, ce qui peut être le cas de la figure 14 si le secteur annulaire est laissé entièrement libre, suspendu seulement par les deux lames 2 faisant ensemble un vé issu du bloc 3.More particularly, at least one said block 3 forms a free inertial mass and is devoid of connection with an external element 9, which may be the case of the figure 14 if the annular sector is left entirely free, suspended only by the two blades 2 together making a vee from the block 3.

Plus particulièrement, l'élément sécable 10 comporte un élément de protection 4 unique. Cette configuration est très sécurisante, si l'élément sécable 10 est compact est facilement accessible latéralement, et elle est préférée chaque fois que c'est possible. Toutefois, dans certaines configurations l'élément sécable 10 est très étendu en longueur, ou bien, une fois assemblé n'est plus accessible de partout, ou bien son implantation empêche l'extraction d'un élément de protection 4 unique, dans ce cas il est utile de disposer d'une pluralité d'éléments de protection 4.More particularly, the breakable element 10 comprises a single protection element 4. This configuration is very reassuring, if the breakable element 10 is compact is easily accessible laterally, and it is preferred whenever possible. However, in some configurations the breakable element 10 is very extended in length, or, once assembled is no longer accessible everywhere, or its implantation prevents the extraction of a single protection element 4, in which case it is useful to have a plurality of protection elements 4.

Dans une application particulièrement avantageuse, au sein de l'élément sécable 10, au moins une dite lame flexible 2 ou lame à cols 20 est précontrainte dans un état multistable, tant que chaque dit élément de protection 4 est solidaire avec le composant 1. Cette configuration est notamment intéressante lorsque l'élément sécable 10 est réalisé en silicium, et lorsque la précontrainte de l'élément flexible qu'il comporte est assurée par une croissance de dioxyde de silicium, qui se fait de façon différenciée sur les zones minces et les zones massives, et entraîne le flambage de l'élément flexible : la partie massive est ici constituée par l'élément de préhension 4 complété par les blocs 3. L'avantage est l'assemblage d'un tel composant sans nécessiter de mise sous contrainte particulière, la précontrainte est assurée, conservée intégralement, et le fonctionnement est parfaitement reproductible une fois que le composant 1 est enfermé et fixé dans la structure 100 dont il fait partie : la destruction de l'élément sécable ne change strictement rien à la précontrainte de l'élément flexible.In a particularly advantageous application, within the breakable element 10, at least one said flexible blade 2 or collar blade 20 is prestressed in a multistable state, as long as each said protection element 4 is integral with the component 1. This configuration is particularly interesting when the breakable element 10 is made of silicon, and when the prestressing of the flexible element that it comprises is ensured by a growth of silicon dioxide, which is differentiated on the thin zones and the massive areas, and causes the buckling of the flexible element: the solid part is here constituted by the gripping element 4 completed by the blocks 3. The advantage is the assembly of such a component without requiring stressing particular, the prestressing is ensured, fully preserved, and the operation is perfectly reproducible once the component 1 is enclosed and fixed in the a structure 100 of which it is part: the destruction of the breakable element does not change anything to the prestressing of the flexible element.

Plus particulièrement, l'élément sécable 10 est plan, s'étend entre deux surfaces supérieure et inférieure parallèles, et est en matériau micro-usinable, ou en silicium et oxyde de silicium, ou en DLC, ou en matériau au moins partiellement amorphe, ou similaire.More particularly, the breakable element 10 is plane, extends between two parallel upper and lower surfaces, and is made of micro-machinable material, or silicon and silicon oxide, or DLC, or at least partially amorphous material, or similar.

Dans une réalisation particulière, cet élément sécable 10 s'étend sur un niveau unique correspondant à l'épaisseur de la plus épaisse dite lame flexible 2 ou lame à cols 20 qu'il comporte.In a particular embodiment, this breakable element 10 extends on a single level corresponding to the thickness of the thickest said flexible blade 2 or blade collar 20 it comprises.

Dans une réalisation particulière, tel que visible sur l'exemple de la figure 11, l'élément sécable 10 s'étend sur une pluralité de niveaux correspondant à chacun à l'épaisseur de la plus épaisse lame flexible 2 ou lame à cols 20 qu'il comporte. Cette figure 11 montre ainsi deux lames croisées, chacune sur un niveau particulier, par exemple chaque niveau est d'abord réalisé séparément en silicium, et les deux niveaux sont assemblés par croissance de dioxyde de silicium au niveau de leur surface de jonction. Ainsi cet élément sécable 10 comporte, sur différents niveaux, des lames flexibles 2 ou lames à cols 20 qui se croisent, en projection sur un plan parallèle au plan de chacun des composants 1.In a particular embodiment, as visible on the example of the figure 11 , the breakable element 10 extends over a plurality of levels each corresponding to the thickness of the thickest flexible blade 2 or blade collar 20 it comprises. This figure 11 thus shows two crossed blades, each on a particular level, for example each level is first made separately silicon, and the two levels are assembled by growth of silicon dioxide at their junction surface. Thus this breakable element 10 comprises, on different levels, flexible blades 2 or cross blades 20 which intersect, in projection on a plane parallel to the plane of each of the components 1.

Dans une réalisation particulière et avantageuse, l'élément sécable 10 est monobloc et indémontable.In a particular and advantageous embodiment, the breakable element 10 is integral and unmountable.

L'invention concerne encore une structure 100 d'oscillateur d'horlogerie, comportant une pluralité de composants 1 fixés les uns aux autres, dont au moins un composant 1 est un constituant d'un élément sécable 10 tel que décrit ci-dessus. Plus particulièrement la structure 100 comporte une pluralité de composants 1 empilés les uns sur les autres, dont au moins un composant 1 est un constituant d'un tel élément sécable 10.The invention also relates to a clock oscillator structure 100, comprising a plurality of components 1 attached to each other, at least one component 1 of which is a component of a breakable element 10 as described above. More particularly, the structure 100 comprises a plurality of components 1 stacked one on the other, of which at least one component 1 is a component of such a breakable element 10.

Plus particulièrement, la structure 100 comporte au moins deux composants 1 empilés l'un sur l'autre, chacun étant un constituant d'un tel élément sécable 10 comportant une dite lame flexible 2 ou lame à cols 20, et ces lames flexibles 2 ou lames à cols 20 sont croisées, en projection sur un plan parallèle au plan de chacun des composants 1.More particularly, the structure 100 comprises at least two components 1 stacked one on the other, each being a component of such a breakable element 10 comprising a said flexible blade 2 or collar blade 20, and these flexible blades 2 or Collar blades 20 are crossed, in projection on a plane parallel to the plane of each of the components 1.

De façon particulière, tous les composants 1 que comporte ladite structure 100 forment un empilement soumis à un effort de serrage par une liaison serrée selon la direction de l'empilement par des moyens de solidarisation qui comportent au moins un rivet assemblé et/ou un ensemble vis-écrou et/ou au moins un composant chassé avec serrage.In particular, all the components 1 that comprises said structure 100 form a stack subjected to a clamping force by a tight connection in the direction of the stack by securing means which comprise at least one assembled rivet and / or a set screw-nut and / or at least one component driven with clamping.

Dans une variante, au moins certains des composants 1 que comporte la structure 100 sont maintenus dans l'empilement par collage. Plus particulièrement, tous les composants 1 que comporte la structure 100 forment un empilement maintenu par collage.In a variant, at least some of the components 1 that the structure 100 comprises are held in the stack by gluing. More particularly, all the components 1 that comprises the structure 100 form a stack maintained by gluing.

Avantageusement, la structure 100 comporte au moins un composant 1 comportant un logement traversant 11 pour le passage et la fixation d'une broche ou d'une goupille ou d'une vis, ce logement traversant 11 comportant une pluralité de ressorts élastiques de centrage 12 et une pluralité de butées de limitation de course radiale 13. Dans le cas d'une élaboration de l'élément sécable 10 en silicium, la position de ces butées 13 est étudiée pour autoriser une course juste suffisante pour ne pas casser le silicium, cette course est voisine de 10 micromètres par rapport au diamètre nominal de la goupille ou de l'élément de liaison d'assemblage.Advantageously, the structure 100 comprises at least one component 1 comprising a through-housing 11 for the passage and fixing of a pin or a pin or a screw, this through-housing 11 having a plurality of resilient centering springs 12 and in the case of an elaboration of the breakable element 10 made of silicon, the position of these stops 13 is studied to allow a stroke just sufficient not to break the silicon, this stroke is close to 10 micrometers with respect to the nominal diameter of the pin or the connecting link element.

Après assemblage et solidarisation par vissage et/ou chassage et/ou collage ou autre, chaque élément sécable 10 est brisé au niveau de chaque liaison sécable 5. Ainsi les éléments de préhension 4 sont éliminés de cette structure 100.After assembly and joining by screwing and / or driving and / or bonding or other, each breakable element 10 is broken at each breakable connection 5. Thus the gripping elements 4 are removed from this structure 100.

L'invention concerne encore un mouvement d'horlogerie 2000 comportant au moins un tel mécanisme oscillateur d'horlogerie 1000, et/ou comportant au moins une telle structure 100, et/ou comportant au moins un dit élément sécable 10.The invention also relates to a watch movement 2000 comprising at least one watch clock oscillator mechanism 1000, and / or comprising at least one such structure 100, and / or comprising at least one said breakable element 10.

L'invention concerne encore une montre 3000 comportant un tel mouvement d'horlogerie 2000.The invention also relates to a watch 3000 comprising such a watch movement 2000.

L'invention concerne encore un procédé d'assemblage d'un mécanisme d'horlogerie comportant au moins un composant 1, lequel comporte au moins une lame flexible 2 ou lame à cols 20 joignant deux blocs 3 chacun plus rigide que cette lame flexible 2 ou lame à cols 20.The invention also relates to a method of assembling a clockwork mechanism comprising at least one component 1, which comprises at least one flexible blade 2 or collar blade 20 joining two blocks 3 each more rigid than this flexible blade 2 or collar blade 20.

Selon ce procédé, on réalise, pour au moins un composant 1, un élément sécable 10 tel que décrit plus haut, on assemble chaque élément sécable 10 avec les autres constituants du mécanisme d'horlogerie, et on sépare ensuite tous les éléments de protection 4, par rupture de chaque liaison sécable 5.According to this method, at least one component 1 is made of a breakable element 10 as described above, each breakable element 10 is assembled with the other components of the clockwork mechanism, and all the protection elements 4 are then separated. by breaking each breakable connection 5.
