Description dƩtaillƩe des modes de rƩalisation prƩfƩrƩsDetailed Description of the Preferred Embodiments

L'invention concerne une structure d'oscillateur d'horlogerie, comportant au moins un bloc sƩcable 10.The invention relates to a watch oscillator structure comprising at least one breakable block 10.

Ce bloc sƩcable 10 est conƧu pour protƩger, pendant la fabrication, la manutention, l'assemblage, les ƩlƩments les plus fragiles d'au moins un composant horloger 1.This breakable block 10 is designed to protect, during manufacture, handling, assembly, the most fragile elements of at least one watch component 1.

Le bloc sĆ©cable 10 est conƧu pour ĆŖtre sĆ©parĆ©, aprĆØs son assemblage avec d'autres Ć©lĆ©ments, en une partie fonctionnelle constituĆ©e par chaque composant 1 qu'il comporte, et une partie sacrificielle qui n'a plus d'utilitĆ© au sein du mĆ©canisme horloger au sein duquel est incorporĆ© le composant 1. Cette partie sacrificielle est conƧue pour une manutention aisĆ©e, par un opĆ©rateur ou par un moyen de manutention automatisĆ©, et elle constitue un bloc de prĆ©hension 4, qui protĆØge chaque composant 1, et en particulier les Ć©lĆ©ments les plus fragiles que renferme ce dernier, jusqu'Ć  la dĆ©solidarisation du bloc de prĆ©hension 4 et des composants 1, par rupture par flexion et/ou torsion, dĆ©coupe avec un outil tel que pince coupante ou scie, ou dĆ©coupe au laser, ou autre.The breakable block 10 is designed to be separated, after its assembly with other elements, into a functional part constituted by each component 1 which it comprises, and a sacrificial part which has no more use within the clock mechanism in which component 1 is incorporated. This sacrificial portion is designed for easy handling, by an operator or by an automated handling means, and constitutes a gripping block 4, which protects each component 1, and in particular the elements the most fragile that encloses the latter, until the separation of the gripping block 4 and the components 1, by breaking by bending and / or torsion, cutting with a tool such as cutting pliers or saw, or laser cutting, or other.

Le bloc sĆ©cable 10 est encore conƧu, dans une variante particuliĆØre dĆ©crite plus loin, pour autoriser la mise sous prĆ©contrainte d'un Ć©lĆ©ment flexible que comporte le composant 1, pendant l'Ć©laboration de cet bloc sĆ©cable 10, et pour conserver la position de prĆ©contrainte pendant tout l'assemblage du composant 1, ce qui rend inutile toute contrainte par un outillage de conformation ou similaire.The breakable block 10 is still 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 block 10, and to maintain the prestressing position during the entire assembly of the component 1, which makes unnecessary any constraint by conformation tooling or the like.

Dans une application prƩfƩrƩe mais non limitative de l'invention, l'ƩlƩment fragile Ơ protƩger est un ƩlƩment 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 particuliĆØrement, le bloc sĆ©cable 10 comporte ainsi au moins un composant 1, lequel comporte au moins une lame flexible 2 ou au moins une lame Ć  cols 20.More particularly, the breakable block 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 Ơ cols 20, joint deux blocs principaux 3, chacun plus rigide que la lame flexible 2 ou la lame Ơ cols 20 concernƩe, au niveau d'encastrements pour la lame flexible 2, ou au niveau de cols 21 pour la lame Ơ cols 20.This flexible blade 2 or collar blade 20, joins two main 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 collar 21 for the collar blade 20.

Selon l'invention, le bloc sƩcable 10 comporte au moins un bloc de prƩhension 4, qui est contigu Ơ au moins un tel bloc principal 3, auquel le bloc de prƩhension 4 est reliƩ par au moins une liaison sƩcable 5. Cette liaison sƩcable 5 est agencƩe pour permettre le dƩtachement du bloc de prƩhension 4 d'avec le composant 1, quand ce composant 1 est fixƩ, par l'intermƩdiaire au moins du bloc principal 3 particulier qui est contigu au bloc de prƩhension 4, Ơ un ƩlƩment externe 9, lequel est plus rigide que la lame flexible 2 ou que les cols de la lame Ơ cols 20.According to the invention, the breakable block 10 comprises at least one gripping block 4, which is contiguous with at least one such main block 3, to which the gripping block 4 is connected by at least one breakable connection 5. This breakable connection 5 is arranged to allow the detachment of the gripping block 4 from the component 1, when this component 1 is fixed, through at least the main block 3 particular which is contiguous to the gripping block 4, to an external element 9 which is stiffer than the flexible blade 2 or the necks of the collar blade 20.

Les figures illustrent, de faƧon non limitative, des lames flexibles 2 droites, des lame Ć  cols 20 avec un col 21 de part et d'autre, ou encore une lame flexible 2 comportant un oeil 25 en sa partie mĆ©diane, on comprend que les formes de ces Ć©lĆ©ments fragiles peuvent ĆŖtre extrĆŖmement 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 faƧon particuliĆØre, le composant 1 est un composant d'oscillateur d'horlogerie, et la lame flexible 2, ou la lame Ć  cols 20, est un composant important de l'oscillateur, et en assure les propriĆ©tĆ©s chronomĆ©triques.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 sĆ©cable 5 peut ĆŖtre rĆ©alisĆ©e de diffĆ©rentes faƧons. Sur les figures 1, 2, 5, 6 cette liaison sĆ©cable 5 comporte une zone de section plus faible que celle du bloc principal 3 et que celle du bloc de prĆ©hension 4 qui lui sont adjacents, Ć  la faƧon d'une plaque de chocolat, ou profil 2D, la liaison sĆ©cable 5 est facile Ć  rompre par flexion. Sur les figures 7 et 9 Ć  14, la liaison sĆ©cable 5 comporte au moins un pont 7, ou plusieurs ponts 7 qui peuvent notamment ĆŖtre sĆ©parĆ©s par des ouvertures traversantes 8, telles que lumiĆØres ou perƧages, tel que visible sur la figure 7, ou encore des ponts minces disjoints comme sur les figures 9 Ć  14. La liaison sĆ©cable 5 peut encore comporter au moins une amorce de rupture rĆ©alisĆ©e dans l'Ć©paisseur de la matiĆØre, tel que visible sur la figure 8, et convient en particulier au cas de l'Ć©laboration par un procĆ©dĆ© multi-couches du bloc sĆ©cable 10, lors duquel des chambres sont mĆ©nagĆ©es dans l'Ć©paisseur du matĆ©riau. Naturellement, la liaison sĆ©cable 5 peut ĆŖtre rĆ©alisĆ©e par panachage de ces diffĆ©rents modes d'Ć©laboration, et peut comporter une zone de section plus faible que celle du bloc principal 3 et du bloc de prĆ©hension 4 qui lui sont adjacents, et/ou comporter un ou plusieurs ponts 7 sĆ©parĆ©s ou non par des ouvertures traversantes 8, et/ou comporter au moins une amorce de rupture rĆ©alisĆ©e dans l'Ć©paisseur de la matiĆØre. De faƧon avantageuse lors de l'emploi de ponts 7, ceux-ci sont conƧus pour ĆŖtre trĆØs facilement rompus par torsion et/ou flexion et/ou par dĆ©coupe.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 main block 3 and that of the gripping block 4 which are adjacent to it, at the way 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 may 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 for the case of the development by a multi-layer method of the breakable block 10, in which chambers are formed in the thickness of the material. Naturally, the breakable connection 5 can be made by mixing these different embodiments, and may comprise a zone of smaller section than that of the main block 3 and the gripping block 4 which are adjacent to it, and / or comprise a or more bridges 7 separated or not by through openings 8, and / or comprise at least one rupture 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 rĆ©alisation particuliĆØre avantageuse, et tel que visible sur les figures, un mĆŖme bloc de prĆ©hension 4 est contigu aux blocs principaux 3 situĆ©s de part et d'autre d'une mĆŖme lame flexible 2 ou lame Ć  cols 20, de maniĆØre Ć  protĆ©ger cette lame flexible 2 ou lame Ć  cols 20.In a particular advantageous embodiment, and as visible in the figures, a same gripping block 4 is contiguous with the main blocks 3 located 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 particuliĆØrement, chaque bloc principal 3 est contigu Ć  un bloc de prĆ©hension 4 Ć  laquelle il est reliĆ© par une liaison sĆ©cable 5.More particularly, each main block 3 is contiguous to a gripping block 4 to which it is connected by a breakable connection 5.

Dans une rĆ©alisation particuliĆØre, au moins un dit bloc principal 3 forme une masse inertielle libre, et est agencĆ© pour ĆŖtre fixĆ© Ć  une autre masse inertielle libre d'un autre bloc sĆ©cable 10, ou Ć  un Ć©lĆ©ment 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 main block 3 forms a free inertial mass, and is arranged to be fixed to another free inertial mass of another breakable block 10, or to an outer member 9; this is for example the case of figure 14 whose annular sector is such an inertial mass.

Au moins un bloc principal 3 comporte au moins une surface d'assemblage 6 ou 11 pour sa fixation rigide Ć  au moins un Ć©lĆ©ment externe 9. Les figures distinguent des surfaces d'assemblage 6 lisses, telles que des alĆ©sages ou similaires, et des logements traversants 11 comportant un relief apte Ć  assurer un serrage : plus particuliĆØrement, 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 pluralitĆ© de ressorts Ć©lastiques de centrage 12 et une pluralitĆ© de butĆ©es de limitation de course radiale 13. Naturellement les surfaces d'appui supĆ©rieure et infĆ©rieure du bloc sĆ©cable 10 sont, surtout dans la rĆ©alisation prĆ©fĆ©rĆ©e et illustrĆ©e par les figures oĆ¹ le bloc sĆ©cable 10 s'Ć©tend entre deux surfaces supĆ©rieure et infĆ©rieure parallĆØles, aussi des surfaces d'assemblage avec des Ć©lĆ©ments externes 9. La figure 2 montre ainsi une structure horlogĆØre 100, notamment une structure d'oscillateur, comportant un empilement d'Ć©lĆ©ments sĆ©cables 10 et d'Ć©lĆ©ments externes 9, qui sont maintenus les uns par rapport aux autres, dans la direction de l'empilement, par d'autres Ć©lĆ©ments externes 9 qui sont des Ć©lĆ©ments de liaison et/ou de fixation : tiges, boulons, vis, rivets, goupilles, ou similaires.At least one main block 3 comprises at least one joining surface 6 or 11 for rigid attachment to at least one external element 9. The figures distinguish smooth assembly surfaces 6, such as bores or the like, and housings through 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 surfaces upper and lower bearing of the breakable block 10 are, especially in the preferred embodiment and illustrated by the figures where the breakable block 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 particuliĆØrement, chaque bloc principal 3 comporte au moins une telle surface d'assemblage 6 ou 11 pour sa fixation rigide Ć  au moins un Ć©lĆ©ment externe 9.More particularly, each main block 3 comprises at least one such assembly surface 6 or 11 for its rigid attachment to at least one external element 9.

Plus particuliĆØrement, au moins un dit bloc principal 3 forme une masse inertielle libre et est dĆ©pourvu de liaison avec un Ć©lĆ©ment externe 9, ce qui peut ĆŖtre le cas de la figure 14 si le secteur annulaire est laissĆ© entiĆØrement libre, suspendu seulement par les deux lames 2 faisant ensemble un vĆ© issu du bloc principal 3.More particularly, at least one said main 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 main block 3.

Plus particuliĆØrement, le bloc sĆ©cable 10 comporte un bloc de prĆ©hension 4 unique. Cette configuration est trĆØs sĆ©curisante, si le bloc sĆ©cable 10 est compact est facilement accessible latĆ©ralement, et elle est prĆ©fĆ©rĆ©e chaque fois que c'est possible. Toutefois, dans certaines configurations le bloc sĆ©cable 10 est trĆØs Ć©tendu en longueur, ou bien, une fois assemblĆ© n'est plus accessible de partout, ou bien son implantation empĆŖche l'extraction d'un bloc de prĆ©hension 4 unique, dans ce cas il est utile de disposer d'une pluralitĆ© de blocs de prĆ©hension 4.More particularly, the breakable block 10 comprises a single gripping block 4. This configuration is very reassuring, if the breakable block 10 is compact is easily accessible laterally, and it is preferred whenever possible. However, in some configurations the breakable block 10 is very extended in length, or, once assembled is no longer accessible from anywhere, or its implementation prevents the extraction of a single gripping block 4, in this case it is useful to have a plurality of gripping blocks 4.

Dans une application particuliĆØrement avantageuse, au sein du bloc sĆ©cable 10, au moins une dite lame flexible 2 ou lame Ć  cols 20 est prĆ©contrainte dans un Ć©tat multistable, tant que chaque dit bloc de prĆ©hension 4 est solidaire avec le composant 1. Cette configuration est notamment intĆ©ressante lorsque le bloc sĆ©cable 10 est rĆ©alisĆ© en silicium, et lorsque la prĆ©contrainte de l'Ć©lĆ©ment flexible qu'il comporte est assurĆ©e par une croissance de dioxyde de silicium, qui se fait de faƧon diffĆ©renciĆ©e sur les zones minces et les zones massives, et entraĆ®ne le flambage de l'Ć©lĆ©ment flexible : la partie massive est ici constituĆ©e par le bloc de prĆ©hension 4 complĆ©tĆ© par les blocs principaux 3. L'avantage est l'assemblage d'un tel composant sans nĆ©cessiter de mise sous contrainte particuliĆØre, la prĆ©contrainte est assurĆ©e, conservĆ©e intĆ©gralement, et le fonctionnement est parfaitement reproductible une fois que le composant 1 est enfermĆ© et fixĆ© dans la structure 100 dont il fait partie : la destruction du bloc sĆ©cable ne change strictement rien Ć  la prĆ©contrainte de l'Ć©lĆ©ment flexible.In a particularly advantageous application, within the breakable block 10, at least one said flexible blade 2 or collar blade 20 is prestressed in a multistable state, as long as each said gripping block 4 is integral with the component 1. This configuration is particularly interesting when the breakable block 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 thin areas and massive areas, and causes the buckling of the flexible element: the solid part is here constituted by the gripping block 4 completed by the main blocks 3. The advantage is the assembly of such a component without requiring particular stressing, the prestressing is ensured, fully preserved, and the operation is perfectly reproducible once the component 1 is enclosed and fixed in the structure 100 of which it is part: the destruction of the breakable block does not change anything to the prestressing of the flexible element.

Plus particuliĆØrement, le bloc sĆ©cable 10 est plan, s'Ć©tend entre deux surfaces supĆ©rieure et infĆ©rieure parallĆØles, et est en matĆ©riau micro-usinable, ou en silicium et oxyde de silicium, ou en DLC, ou en matĆ©riau au moins partiellement amorphe, ou similaire.More particularly, the breakable block 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 rĆ©alisation particuliĆØre, ce bloc sĆ©cable 10 s'Ć©tend sur un niveau unique correspondant Ć  l'Ć©paisseur de la plus Ć©paisse dite lame flexible 2 ou lame Ć  cols 20 qu'il comporte.In a particular embodiment, this breakable block 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 rĆ©alisation particuliĆØre, tel que visible sur l'exemple de la figure 11, le bloc sĆ©cable 10 s'Ć©tend sur une pluralitĆ© de niveaux correspondant Ć  chacun Ć  l'Ć©paisseur de la plus Ć©paisse lame flexible 2 ou lame Ć  cols 20 qu'il comporte. Cette figure 11 montre ainsi deux lames croisĆ©es, chacune sur un niveau particulier, par exemple chaque niveau est d'abord rĆ©alisĆ© sĆ©parĆ©ment en silicium, et les deux niveaux sont assemblĆ©s par croissance de dioxyde de silicium au niveau de leur surface de jonction. Ainsi ce bloc sĆ©cable 10 comporte, sur diffĆ©rents niveaux, des lames flexibles 2 ou lames Ć  cols 20 qui se croisent, en projection sur un plan parallĆØle au plan de chacun des composants 1.In a particular embodiment, as visible on the example of the figure 11 , the breakable block 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 block 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 rĆ©alisation particuliĆØre et avantageuse, le bloc sĆ©cable 10 est monobloc et indĆ©montable.In a particular and advantageous embodiment, the breakable block 10 is integral and unmountable.

L'invention concerne encore une structure 100 d'oscillateur d'horlogerie, comportant une pluralitĆ© de composants 1 fixĆ©s les uns aux autres, dont au moins un composant 1 est un constituant d'un bloc sĆ©cable 10 tel que dĆ©crit ci-dessus. Plus particuliĆØrement la structure 100 comporte une pluralitĆ© de composants 1 empilĆ©s les uns sur les autres, dont au moins un composant 1 est un constituant d'un tel bloc sĆ©cable 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 block 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 constituent of such a breakable block 10.

Plus particuliĆØrement, la structure 100 comporte au moins deux composants 1 empilĆ©s l'un sur l'autre, chacun Ć©tant un constituant d'un tel bloc sĆ©cable 10 comportant une dite lame flexible 2 ou lame Ć  cols 20, et ces lames flexibles 2 ou lames Ć  cols 20 sont croisĆ©es, en projection sur un plan parallĆØle au plan de chacun des composants 1.More particularly, the structure 100 comprises at least two components 1 stacked one on top of the other, each being a constituent of such a breakable block 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 faƧon particuliĆØre, tous les composants 1 que comporte ladite structure 100 forment un empilement soumis Ć  un effort de serrage par une liaison serrĆ©e selon la direction de l'empilement par des moyens de solidarisation qui comportent au moins un rivet assemblĆ© et/ou un ensemble vis-Ć©crou et/ou au moins un composant chassĆ© avec serrage.In particular, all the components 1 that comprises said structure 100 form a stack subjected to a tightening force by a tight connection according to the direction of the stack by securing means which comprise at least one assembled rivet and / or a screw-nut assembly 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 particuliĆØrement, 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 pluralitĆ© de ressorts Ć©lastiques de centrage 12 et une pluralitĆ© de butĆ©es de limitation de course radiale 13. Dans le cas d'une Ć©laboration du bloc sĆ©cable 10 en silicium, la position de ces butĆ©es 13 est Ć©tudiĆ©e pour autoriser une course juste suffisante pour ne pas casser le silicium, cette course est voisine de 10 micromĆØtres par rapport au diamĆØtre nominal de la goupille ou de l'Ć©lĆ©ment 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 block 10 made of silicon, the position of these stops 13 is studied to allow a fair stroke sufficient to not break the silicon, this race is close to 10 micrometers with respect to the nominal diameter of the pin or the connecting connection element.

AprĆØs assemblage et solidarisation par vissage et/ou chassage et/ou collage ou autre, chaque bloc sĆ©cable 10 est brisĆ© au niveau de chaque liaison sĆ©cable 5. Ainsi les Ć©lĆ©ments de prĆ©hension 4 sont Ć©liminĆ©s de cette structure 100.After assembly and joining by screwing and / or driving and / or bonding or other, each breakable block 10 is broken at each breakable connection 5. Thus the gripping elements 4 are removed from this structure 100.

L'invention concerne encore un mƩcanisme oscillateur d'horlogerie 1000 comportant au moins une telle structure 100.The invention also relates to a clock oscillator mechanism 1000 comprising at least one such structure 100.

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