Definitions

  • the present invention relates to an arrangement for the elastic articulated connection between two components of a watch assembly, particularly for a wristwatch bracelet, arranged either at a clasp or at the meshes of the bracelet. It also relates to a clasp, a bracelet and a wristwatch as such comprising such an arrangement.
  • the figure 1 illustrates a solution described in the document EP1654950 to implement the elastic locking and unlocking of two movable blades 1, 2 of a bracelet clasp.
  • the first movable blade 1 is locked in the folded position on a second blade 2 by hooking a latching lever 3 against a latching stud under the effect of elastic means.

  • This embodiment makes it possible to guarantee very good locking security while optimizing the force required for the opening of the clasp, which makes it a very satisfactory solution in terms of security of closure and manipulation.
  • documents CH689931 and CH699044 both describe an embodiment of clasps for bracelets in which the actuation of a locking mechanism involves the compression of a helical spring extending longitudinally along the wristband within an opening formed within a blade of clasp.
  • This embodiment is less efficient than the previous ones in that the locking force obtained with the use of this type of spring is not optimal and not user friendly when handling such a clasp.
  • the document EP0908112 discloses a locking device of a clasp having a lid which is resiliently biased by a helical spring working in torsion.
  • This spring is arranged around an axis of articulation which coincides with the axis of pivoting of the lid. A first end of the spring is bent so as to come into play in a cutout of the cover, while a second end of the spring is pressed against a blade of the clasp. It appears that the choice of a spring working in torsion makes it more complex to obtain a satisfactory elastic effect and a stable articulation movement due to the assembly games of such a spring.
  • a general object of the invention is to provide an elastic articulated connection solution between two components of a watch assembly, which achieves an optimal compromise between the performance of the elastic assembly and its bulk.
  • such a solution is more particularly sought for an application within a bracelet clasp, or for the articulation of blades or bracelet stitches for a wristwatch.

  • a second step then consists in assembling the parts distinct. This assembly can for example be done by laser welding. To minimize the stresses during these welds, the ends to be welded of each of these distinct parts may have a cut-out staircase 81.
  • This manufacture uses a wire of preferably square or rectangle section, with a spacing between the turns chosen to obtain the recall couple wanted. This manufacturing method makes it possible in particular to generate contact between the turns of the spring of the central portion 35 to reach a maximum torque.

Description

IntroductionIntroduction

La présente invention concerne un agencement pour la liaison articulée élastique entre deux composants d'un assemblage horloger, notamment pour un bracelet de montre-bracelet, disposé soit au niveau d'un fermoir, soit au niveau des mailles de ce bracelet. Elle porte aussi sur un fermoir, un bracelet et une montre-bracelet en tant que tels comprenant un tel agencement.The present invention relates to an arrangement for the elastic articulated connection between two components of a watch assembly, particularly for a wristwatch bracelet, arranged either at a clasp or at the meshes of the bracelet. It also relates to a clasp, a bracelet and a wristwatch as such comprising such an arrangement.

Etat de l'ArtState of the art

La figure 1 illustre une solution décrite dans le document EP1654950 pour mettre en oeuvre le verrouillage et le déverrouillage élastiques de deux lames mobiles 1, 2 d'un fermoir de bracelet. La première lame mobile 1 est verrouillée en position repliée sur une deuxième lame 2 par le crochetage d'un levier d'accrochage 3 à l'encontre d'un plot d'accrochage sous l'effet de moyens élastiques. Dans un premier mode de réalisation, ces moyens élastiques sont constitués par des ressorts lames 5 prévus pour travailler en flexion, qui comprennent une première extrémité libre 6 en appui sur une tige 8 d'un organe de liaison intermédiaire et une seconde extrémité 7 en appui contre la face interne de la paroi supérieure du levier d'accrochage.The figure 1 illustrates a solution described in the document EP1654950 to implement the elastic locking and unlocking of two movable blades 1, 2 of a bracelet clasp. The first movable blade 1 is locked in the folded position on a second blade 2 by hooking a latching lever 3 against a latching stud under the effect of elastic means. In a first embodiment, these resilient means consist of leaf springs 5 designed to work in bending, which comprise a first free end 6 bearing on a rod 8 of an intermediate connecting member and a second end 7 in abutment. against the inner face of the upper wall of the hooking lever.

Cette réalisation permet de garantir une très bonne sécurité de verrouillage tout en optimisant la force requise pour l'ouverture du fermoir, ce qui en fait une solution très satisfaisante en termes de sécurité de fermeture et de manipulation.This embodiment makes it possible to guarantee very good locking security while optimizing the force required for the opening of the clasp, which makes it a very satisfactory solution in terms of security of closure and manipulation.

Ce même document décrit un second mode de réalisation, représenté par la figure 2, dans lequel les moyens élastiques sont constitués par un ressort hélicoïdal 5' prévus pour travailler en compression.This same document describes a second embodiment, represented by the figure 2 , in which the elastic means are constituted by a helical spring 5 'provided for working in compression.

De nombreux autres documents décrivent d'autres agencements pour la liaison entre deux composants d'un bracelet pour montre-bracelet, qui reposent toutes sur l'utilisation de moyens de rappel élastiques à base de ressorts hélicoïdaux travaillant en compression.Numerous other documents describe other arrangements for the connection between two components of a wristwatch bracelet, all of which rely on the use of resilient return means based on coil springs working in compression.

A titre d'exemple, les documents CH689931 et CH699044 décrivent tous deux une réalisation de fermoirs pour bracelets dans lesquels l'actionnement d'un mécanisme de verrouillage implique la compression d'un ressort hélicoïdal s'étendant longitudinalement le long du bracelet au sein d'une ouverture formée au sein d'une lame du fermoir. Cette réalisation est moins performante que les précédentes en ce que la force de verrouillage obtenue avec l'utilisation de ce type de ressort n'est pas optimale et non conviviale lors de la manipulation d'un tel fermoir.For example, documents CH689931 and CH699044 both describe an embodiment of clasps for bracelets in which the actuation of a locking mechanism involves the compression of a helical spring extending longitudinally along the wristband within an opening formed within a blade of clasp. This embodiment is less efficient than the previous ones in that the locking force obtained with the use of this type of spring is not optimal and not user friendly when handling such a clasp.

Les documents EP1374716 et EP0350785 décrivent de même des réalisations de fermoirs pour bracelets dans lesquels l'actionnement d'un mécanisme de verrouillage implique la compression d'un ressort hélicoïdal, ce dernier s'étendant dans une direction perpendiculaire à la direction longitudinale du bracelet.The documents EP1374716 and EP0350785 likewise describe embodiments of clasps for bracelets in which the actuation of a locking mechanism involves the compression of a helical spring, the latter extending in a direction perpendicular to the longitudinal direction of the wristband.

Le document EP0908112 divulgue un dispositif de verrouillage d'un fermoir doté d'un couvercle qui est rappelé élastiquement par un ressort hélicoïdal travaillant en torsion. Ce ressort est agencé autour d'un axe d'articulation qui coïncide avec l'axe de pivotement du couvercle. Une première extrémité du ressort est coudée de façon à venir s'insérer à jeu dans une découpe du couvercle, tandis qu'une deuxième extrémité du ressort est pressée à l'encontre d'une lame du fermoir. Il apparaît que le choix d'un ressort travaillant en torsion rend plus complexe l'obtention d'un effet élastique satisfaisant et d'un mouvement d'articulation stable du fait des jeux d'assemblage d'un tel ressort.The document EP0908112 discloses a locking device of a clasp having a lid which is resiliently biased by a helical spring working in torsion. This spring is arranged around an axis of articulation which coincides with the axis of pivoting of the lid. A first end of the spring is bent so as to come into play in a cutout of the cover, while a second end of the spring is pressed against a blade of the clasp. It appears that the choice of a spring working in torsion makes it more complex to obtain a satisfactory elastic effect and a stable articulation movement due to the assembly games of such a spring.

Finalement, toutes ces solutions existantes ne permettent pas d'atteindre un compromis maximal entre la sécurité du verrouillage ou de l'articulation élastique, la convivialité de son fonctionnement, et l'encombrement de la solution. En effet, les solutions les plus performantes présentent l'inconvénient d'un encombrement important, ce qui devient incompatible avec certains aspects esthétiques recherchés et limite leurs utilisations. D'autres solutions moins encombrantes sont en revanche nettement moins performantes.Finally, all these existing solutions do not make it possible to reach a maximum compromise between the safety of the locking or the elastic articulation, the user-friendliness of its operation, and the size of the solution. Indeed, the most powerful solutions have the disadvantage of a large footprint, which becomes incompatible with certain aesthetic aspects sought and limits their use. Other less bulky solutions are however significantly less efficient.

On note de plus que les réalisations précitées ont été développées dans le cadre d'un fermoir pour bracelet mais peuvent également s'appliquer pour la liaison entre des mailles de bracelet ou plus généralement pour tous composants horlogers articulés élastiquement entre eux. Par exemple, cette solution peut également s'appliquer pour la liaison entre une boîte de montre et un brin de bracelet.It is further noted that the above-mentioned embodiments have been developed in the context of a bracelet clasp but can also be applied for the connection between bracelet stitches or more generally for all clock components hinged elastically to each other. For example, this solution can also be applied for the connection between a watch case and a bracelet strand.

Ainsi, un objet général de l'invention est de proposer une solution de liaison articulée élastique entre deux composants d'un assemblage horloger, qui atteint un compromis optimal entre la performance de l'assemblage élastique et son encombrement.Thus, a general object of the invention is to provide an elastic articulated connection solution between two components of a watch assembly, which achieves an optimal compromise between the performance of the elastic assembly and its bulk.

Notamment, une telle solution est plus particulièrement recherchée pour une application au sein d'un fermoir de bracelet, ou pour l'articulation de lames ou mailles de bracelet pour montre-bracelet.In particular, such a solution is more particularly sought for an application within a bracelet clasp, or for the articulation of blades or bracelet stitches for a wristwatch.

L'invention repose donc sur l'utilisation d'au moins un ressort travaillant en torsion. Comme cela va être illustré par la suite, l'utilisation d'une telle solution permet de réduire fortement l'encombrement de la solution.The invention is therefore based on the use of at least one spring working in torsion. As will be illustrated later, the use of such a solution can greatly reduce the size of the solution.

Pour la suite de la description, les mêmes références seront utilisées pour désigner des éléments équivalents sur les différents modes de réalisation de l'invention pour faciliter leur compréhension.For the rest of the description, the same references will be used to designate equivalent elements on the various embodiments of the invention to facilitate their understanding.

Les figures 3 à 8 illustrent un fermoir pour bracelet selon un premier mode de réalisation de l'invention. Ce fermoir comprend deux lames 10, 20 articulées selon un principe similaire à celui décrit dans le document EP1654950 qui ne sera pas détaillé de nouveau à ce stade. Celui-ci met en oeuvre deux ressorts 25 de torsion, notamment deux ressorts hélicoïdaux, agencés autour de l'axe d'articulation 24 du levier d'accrochage 23. L'invention est ainsi mise en oeuvre au niveau de l'articulation d'un élément de verrouillage/déverrouillage d'un fermoir pour bracelet.The Figures 3 to 8 illustrate a clasp for a bracelet according to a first embodiment of the invention. This clasp comprises two blades 10, articulated according to a principle similar to that described in the document EP1654950 which will not be detailed again at this stage. This uses two torsion springs 25, in particular two helical springs, arranged around the hinge axis 24 of the coupling lever 23. The invention is thus implemented at the hinge joint. an element for locking / unlocking a bracelet clasp.

Ainsi, le fermoir selon ce premier mode de réalisation comprend une première lame 10 portant un plot d'accrochage 13 vers une première extrémité portant une première maille de bracelet composée de plusieurs maillons 18 liés de manière articulée par des axes 19. Ces éléments sont plus particulièrement visibles sur les figures 6 à 8. Cette première maille constitue une extrémité d'un premier brin de bracelet. Cette première lame 10 est liée de manière articulée à une seconde lame 20 autour d'un axe d'articulation 11 au niveau de sa seconde extrémité.Thus, the clasp according to this first embodiment comprises a first blade 10 carrying a latching pin 13 to a first end carrying a first bracelet mesh composed of several links 18 hingedly connected by pins 19. These elements are more particularly visible on Figures 6 to 8 . This first mesh is an end of a first bracelet strand. This first blade 10 is hingedly connected to a second blade 20 about a hinge axis 11 at its second end.

Cette seconde lame 20 porte vers son extrémité libre opposée à l'axe d'articulation 11 un levier d'accrochage 23 qui comprend un crochet coopérant avec le plot d'accrochage 13. Le levier d'accrochage 23 est articulé autour d'un axe d'articulation 24 qui s'étend sur sensiblement toute la largeur du fermoir, dans une direction perpendiculaire à sa direction longitudinale. Deux ressorts 25 de torsion sont agencés autour de cet axe d'articulation 24, comme cela sera détaillé ci-dessous. Une maille de bracelet est de plus agencée à cette même extrémité de la seconde lame 20, et constitue une extrémité du second brin de bracelet. Cette maille comprend un maillon central 28 et deux maillons de bord 22 liés à l'axe d'articulation 24 du levier d'accrochage 23. Cette première rangée de maillons est liée à d'autres maillons 28'. Tous ces maillons de la maille sont liés par des axes 29. Enfin, un organe de préhension 30 est solidaire du levier d'accrochage 23 pour faciliter sa manipulation. Comme cela est particulièrement visible sur la figure 3, en position fermée du fermoir, les différents maillons 18, 22, 28, 28' des deux lames 10, 20 forment un ensemble continu, au sein duquel l'organe de préhension 30 est intégré de manière discrète mais facilement manipulable, entre les maillons du fermoir, pour assurer une esthétique attrayante. Le levier d'accrochage 23 se présente sous une forme similaire à celle d'un maillon du bracelet. Le bracelet présente ainsi une apparence continue sur tout le pourtour du poignet en configuration fermée du fermoir, lequel est finalement très peu visible, notamment grâce à sa faible épaisseur du fait de l'encombrement réduit de son mécanisme, explicité ci-dessous.This second blade 20 carries towards its free end opposite to the hinge axis 11 a hooking lever 23 which comprises a hook cooperating with the hooking stud 13. The hooking lever 23 is articulated about an axis articulation 24 which extends over substantially the entire width of the clasp, in a direction perpendicular to its direction longitudinal. Two torsion springs are arranged around this hinge axis 24, as will be detailed below. A bracelet mesh is further arranged at the same end of the second blade 20, and constitutes an end of the second bracelet strand. This mesh comprises a central link 28 and two edge links 22 connected to the hinge axis 24 of the engagement lever 23. This first row of links is linked to other links 28 '. All these links of the mesh are linked by pins 29. Finally, a gripping member 30 is integral with the hooking lever 23 to facilitate its handling. As is particularly visible on the figure 3 , in the closed position of the clasp, the different links 18, 22, 28, 28 'of the two blades 10, 20 form a continuous assembly, in which the gripping member 30 is integrated in a discrete but easily manipulable manner, between the links clasp, to ensure an attractive aesthetic. The hooking lever 23 is in a form similar to that of a bracelet link. The bracelet thus has a continuous appearance all around the wrist in the closed configuration of the clasp, which is finally very little visible, especially due to its small thickness due to the reduced size of its mechanism, explained below.

La figure 5 représente une vue en perspective d'un ressort 25 utilisé dans ce premier mode de réalisation. Un tel ressort 25 comprend une partie centrale 35 hélicoïdale se composant de spires, remplissant la fonction élastique du ressort, et disposée entre deux extrémités 36, 37. Chacune de ces extrémités 36, 37 comprend une forme sensiblement cylindrique, dont le pourtour comprend au moins une saillie, respectivement 38, 39. De plus, des découpes circulaires 32, 33 sont réalisées au centre de respectivement chacune des deux extrémités 36, 37, et s'étendent dans la direction de l'axe du ressort. Dans ce mode de réalisation, le fermoir utilise deux ressorts tels que décrits ci-dessus, symétriques par rapport au plan longitudinal du fermoir et alignés.The figure 5 is a perspective view of a spring 25 used in this first embodiment. Such a spring 25 comprises a helical central part consisting of turns, filling the elastic function of the spring, and disposed between two ends 36, 37. Each of these ends 36, 37 comprises a substantially cylindrical shape, the periphery of which comprises at least a protrusion, respectively 38, 39. In addition, circular cutouts 32, 33 are made in the center of respectively each of the two ends 36, 37, and extend in the direction of the axis of the spring. In this embodiment, the clasp uses two springs as described above, symmetrical with respect to the longitudinal plane of the clasp and aligned.

Le fonctionnement de la solution selon ce premier mode de réalisation va mieux être illustré par les vues en coupes des figures 6 à 8.The operation of the solution according to this first embodiment will be better illustrated by the sectional views of the Figures 6 to 8 .

Les figures 6a et 6b illustrent ainsi une coupe du fermoir selon le premier mode de réalisation selon un plan longitudinal I-I au niveau de la première extrémité 36 d'un ressort 25. Il apparait que cette extrémité 36 est disposée de sorte que sa saillie 38 soit logée au sein d'une ouverture aménagée au sein du levier d'accrochage 23, cette ouverture formant une contre-forme de la saillie 38. Cette architecture permet de bloquer en rotation, c'est-à-dire dans les deux sens de rotation, l'extrémité 36 du ressort 25 relativement au levier d'accrochage 23. En remarque, cette contre-forme peut présenter une forme idéale qui assure un véritable blocage de la saillie et donc de l'extrémité du ressort ou en variante peut être sensiblement complémentaire seulement, laisser un jeu radial au niveau de la liaison de la saillie et de sa contre-forme, voire laisser un débattement angulaire de la saillie entre deux butées définies par la contre-forme. La découpe intérieure 32 est positionnée à moindre jeu autour de l'axe d'articulation 24.The Figures 6a and 6b thus illustrate a section of the clasp according to the first embodiment along a longitudinal plane II at the first end 36 of a spring 25. It appears that this end 36 is arranged so that its projection 38 is housed within an opening arranged within the hooking lever 23, this opening forming a counter-form of the projection 38. This architecture allows to block in rotation, that is to say in both directions of rotation, the end 36 of the spring 25 relative to the hooking lever 23. Note that this against-shape may have an ideal shape that ensures a true blocking of the projection and therefore the end of the spring or alternatively may be substantially complementary only leave a radial clearance at the connection of the projection and its counter-form, or even allow an angular displacement of the projection between two stops defined by the counter-form. The inner cut 32 is positioned at least clearance around the hinge axis 24.

Les figures 7a et 7b illustrent ce même fermoir au niveau de la partie centrale du ressort 25. On retrouve ainsi une portion de spire de la partie centrale 35 du ressort 25 qui entoure à jeu l'axe d'articulation 24.The Figures 7a and 7b illustrate the same clasp at the central portion of the spring 25. There is thus a portion of turn of the central portion 35 of the spring 25 which surrounds clearance the hinge axis 24.

Enfin, les figures 8a et 8b illustrent une coupe du fermoir selon le premier mode de réalisation selon un plan longitudinal au niveau de la seconde extrémité 37 d'un ressort 25. Ses saillies 39 coopèrent avec des ouvertures correspondantes, qui leur sont sensiblement complémentaires, voire complémentaires, et qui sont agencées dans la surface intérieure d'un maillon de bord 22 du fermoir, ce qui permet de bloquer en rotation cette seconde extrémité. Cette dernière peut être chassée, soudée, ou brasée sur le maillon de bord 22 pour améliorer sa fixation, voire fixée par tout autre moyen comme le collage. En variante, elle n'est pas fixée mais bloquée avec jeu, voire débattement radial (angulaire) limité. La découpe intérieure 33 est positionnée à moindre jeu autour de l'axe d'articulation 24.Finally, Figures 8a and 8b illustrate a section of the clasp according to the first embodiment in a longitudinal plane at the second end 37 of a spring 25. Its projections 39 cooperate with corresponding openings, which are substantially complementary or even complementary, and which are arranged in the inner surface of an edge link 22 of the clasp, which makes it possible to lock this second end in rotation. The latter can be driven, welded, or brazed to the edge link 22 to improve its fixation, or fixed by any other medium like collage. Alternatively, it is not fixed but blocked with clearance, or limited radial (angular) movement. The inner cutout 33 is positioned at least clearance around the hinge axis 24.

Le diamètre intérieur obtenu par au moins une découpe latérale 32, 33 est inférieur au diamètre intérieur des spires de la partie centrale 35 du ressort 25. De plus, le diamètre extérieur (en faisant abstraction des saillies 38, 39) des extrémités 36 ,37 (ou d'au moins une extrémité) du ressort 25 est supérieur au diamètre extérieur des spires de la partie centrale 35 du ressort. Préférentiellement, les saillies sont dans le prolongement du diamètre extérieur des extrémités 36, 37. Par cette construction, le guidage de la rotation du levier d'accrochage 23 est assuré par les extrémités 36, 37 du ressort, en contact dans sa découpe intérieure avec l'axe d'articulation 24 et dans sa partie extérieure avec d'une part le levier d'accrochage 23 et d'autre part un maillon de bord 22. Ce guidage devient ainsi indépendant des fluctuations géométriques des spires de sa partie centrale. Les extrémités du ressort forment donc des surfaces de guidage du mouvement relatif des deux composants horlogers, ce qui stabilise ce mouvement et notamment son rappel élastique.The inside diameter obtained by at least one lateral cutout 32, 33 is smaller than the inner diameter of the turns of the central portion 35 of the spring 25. In addition, the outside diameter (excluding the projections 38, 39) of the ends 36, 37 (or at least one end) of the spring 25 is greater than the outer diameter of the turns of the central portion 35 of the spring. Preferably, the projections are in the extension of the outer diameter of the ends 36, 37. By this construction, the guide of the rotation of the engaging lever 23 is provided by the ends 36, 37 of the spring, in contact in its inner cutout with the hinge pin 24 and in its outer part with on the one hand the hooking lever 23 and on the other hand an edge link 22. This guidance thus becomes independent of the geometric fluctuations of the turns of its central portion. The ends of the spring therefore form guiding surfaces of the relative movement of the two watch components, which stabilizes this movement and in particular its elastic return.

D'autres modes de réalisation de fermoirs vont maintenant être décrits, mettant en oeuvre d'autres types de mécanismes de verrouillage/déverrouillage d'un fermoir, avec d'autres moyens élastiques de torsion. Comme l'invention ne porte pas sur le dispositif de verrouillage/déverrouillage d'un fermoir en tant que tel, ce dernier sera décrit de manière succincte par la suite.Other embodiments of clasps will now be described, implementing other types of mechanisms for locking / unlocking a clasp, with other elastic torsion means. As the invention does not relate to the locking / unlocking device of a clasp as such, the latter will be briefly described later.

Les figures 9 à 15 illustrent un fermoir selon un deuxième mode de réalisation de l'invention.The Figures 9 to 15 illustrate a clasp according to a second embodiment of the invention.

Ce fermoir, notamment illustré par les figures 9 et 10, comprend de même deux lames articulées, mais, à la différence du mode de réalisation précédent, est doté d'un couvercle qui recouvre le mécanisme en position fermée du fermoir. Ce couvercle comprend une première partie sous forme d'onglet mobile 41, pivotable par ses deux extrémités latérales, qui est solidaire d'un levier d'accrochage 23 qui remplit la fonction du levier d'accrochage du mode de réalisation précédent, et une seconde partie fixe 40.This clasp, in particular illustrated by Figures 9 and 10 , likewise comprises two articulated blades, but, unlike the previous embodiment, is provided with a cover which covers the mechanism in the closed position of the clasp. This cover comprises a first portion in the form of movable tab 41, pivotable by its two lateral ends, which is integral with a hooking lever 23 which performs the function of the hooking lever of the previous embodiment, and a second fixed part 40.

Dans cette réalisation, un ressort 25 différent, représenté par les figures 11 et 12, est utilisé. Il comprend toujours une partie centrale 35 comprenant des spires, pour remplir la fonction élastique, entre deux extrémités 36, 37. Toutefois, ces deux extrémités présentent une forme légèrement différente qui va être explicitée en référence aux figures suivantes.In this embodiment, a different spring 25, represented by the Figures 11 and 12 , is used. It always comprises a central portion 35 comprising turns, to fulfill the elastic function, between two ends 36, 37. However, these two ends have a slightly different shape which will be explained with reference to the following figures.

Les figures 13a et 13b illustrent ainsi une coupe du fermoir selon un plan longitudinal I-I au niveau de la première extrémité 36 d'un ressort 25. Il apparait que cette extrémité 36 est disposée de sorte que la saillie 38 soit logée au sein d'une ouverture aménagée au sein d'une partie solidaire de la seconde partie fixe 40 du couvercle, formant une contre-forme de la saillie 38. Cette architecture permet de bloquer en rotation l'extrémité 36 du ressort 25 relativement au couvercle.The Figures 13a and 13b thus illustrate a cut of the clasp along a longitudinal plane II at the first end 36 of a spring 25. It appears that this end 36 is arranged so that the projection 38 is housed within an opening arranged within an integral portion of the second fixed portion 40 of the cover, forming a counter-shape of the projection 38. This architecture is used to lock in rotation the end 36 of the spring 25 relative to the cover.

Les figures 14a et 14b illustrent ce même fermoir par une coupe II-II au niveau de la partie centrale du ressort 25. On retrouve ainsi une portion de spire du ressort 25 qui entoure une barrette, notamment une barrette à ressort ou barrette amovible, formant un axe d'articulation 24.The figures 14a and 14b illustrate this same clasp by a section II-II at the central portion of the spring 25. There is thus a portion of turn of the spring 25 which surrounds a bar, in particular a spring bar or removable bar, forming a hinge axis 24.

Enfin, les figures 15a et 15b illustrent une coupe III-III du fermoir au niveau de la seconde extrémité 37 d'un ressort 35. Sa saillie 39 coopère avec des ouvertures correspondantes agencées dans la surface intérieure de l'onglet mobile 41, ce qui permet de bloquer en rotation cette seconde extrémité relativement à l'onglet mobile. Cette seconde extrémité comprend aussi un méplat 34 sur sa circonférence, pour coopérer avec un lamage d'une maille solidaire du couvercle. Ce méplat permet d'autre part de former une butée 31 qui délimite l'ébat latéral du ressort 25. Enfin, cette seconde extrémité 37 du ressort 25 comprend de plus une découpe traversante 43, radiale, complémentaire d'une découpe réalisée dans l'onglet mobile 41 du couvercle, pour permettre le montage/démontage du couvercle de manière conventionnelle en permettant un accès libre aux extrémités de la barrette 24.Finally, Figures 15a and 15b illustrate a III-III section of the clasp at the second end 37 of a spring 35. Its projection 39 cooperates with corresponding openings arranged in the inner surface of the tab mobile 41, which allows to lock in rotation this second end relative to the movable tab. This second end also comprises a flat portion 34 on its circumference, to cooperate with a countersink of a mesh integral with the lid. This flat part makes it possible, on the other hand, to form a stop 31 which delimits the lateral fretting of the spring 25. Finally, this second end 37 of the spring 25 furthermore comprises a radial through cut 43, complementary to a cut made in FIG. mobile tab 41 of the cover, to allow mounting / disassembly of the cover in a conventional manner by allowing free access to the ends of the bar 24.

Comme dans le mode de réalisation précédent, le diamètre d'au moins une découpe latérale 32, 33 d'une extrémité 36, 37 du ressort 25 est inférieur au diamètre intérieur des spires de la partie centrale 35 du ressort 25 de sorte que le ressort 25 peut pivoter à moindre jeu sur l'axe 24. De plus, le diamètre extérieur (en faisant abstraction des saillies 38, 39) des extrémités 36, 37 (ou d'au moins une extrémité) du ressort 25 est supérieur au diamètre extérieur des spires de la partie centrale 35 du ressort. Par cette construction, le guidage de la rotation du levier d'accrochage et de l'onglet mobile est assuré par les extrémités du ressort, de manière indépendante des fluctuations géométriques des spires de sa partie centrale.As in the previous embodiment, the diameter of at least one lateral cutout 32, 33 of one end 36, 37 of the spring 25 is smaller than the inside diameter of the turns of the central portion 35 of the spring 25 so that the spring 25 can be pivoted with less play on the axis 24. In addition, the outside diameter (ignoring the projections 38, 39) of the ends 36, 37 (or at least one end) of the spring 25 is greater than the outside diameter. turns of the central portion 35 of the spring. By this construction, the guide of the rotation of the engaging lever and the movable tab is provided by the ends of the spring, independently of the geometric fluctuations of the turns of its central portion.

Les figures 16 à 23 illustrent un fermoir selon un troisième mode de réalisation de l'invention.The Figures 16 to 23 illustrate a clasp according to a third embodiment of the invention.

Ce fermoir, notamment illustré par les figures 16 et 17, est très proche de la réalisation précédente. Il diffère en ce que le levier d'accrochage 23, solidaire de l'onglet mobile 41 du couvercle, est pivotable dans sa partie centrale par l'intermédiaire d'un maillon central formant un composant solidaire du levier d'accrochage du premier mode de réalisation.This clasp, in particular illustrated by Figures 16 and 17 , is very close to the previous realization. It differs in that the hooking lever 23, secured to the movable tab 41 of the cover, is pivotable in its central portion via a central link forming a component integral with the engaging lever of the first mode of production.

Dans cette réalisation, un unique ressort 25 est utilisé, représenté par les figures 18 et 19. Ce ressort comprend deux zones élastiques dites « ressort » 55 composées de spires, agencées respectivement entre une partie centrale 50 et chacune des deux extrémités 56, 57 du ressort. Chaque extrémité peut comprendre des formes semblables aux réalisations décrites précédemment, et notamment comprendre au moins une saillie 58, 59. La partie centrale 50 comprend une forme cylindrique comprenant aussi au moins une saillie 51. De plus, des découpes traversantes 52, 53 sont aussi prévues au niveau des deux extrémités 56, 57 et de la partie centrale 50 du ressort. D'autres aspects de ce ressort sont détaillés ci-après.In this embodiment, a single spring 25 is used, represented by the Figures 18 and 19 . This spring comprises two elastic zones called "spring" 55 composed of turns, respectively arranged between a central portion 50 and each of the two ends 56, 57 of the spring. Each end may comprise shapes similar to the embodiments described above, and include at least one projection 58, 59. The central portion 50 comprises a cylindrical shape also comprising at least one projection 51. In addition, through cuts 52, 53 are also provided at the two ends 56, 57 and the central portion 50 of the spring. Other aspects of this jurisdiction are detailed below.

Les figures 20a et 20b illustrent ainsi une coupe du fermoir selon un plan longitudinal I-I au niveau de la partie centrale 50 du ressort. Il apparait que la saillie 51 est logée au sein d'une ouverture aménagée au sein de la maille mobile qui est liée au levier d'accrochage 23 et à l'onglet mobile 41 du couvercle, cette ouverture formant une contre-forme de la saillie. Cette architecture permet de bloquer en rotation la partie centrale 50 du ressort 25 relativement à cet onglet mobile 41.The Figures 20a and 20b thus illustrate a section of the clasp along a longitudinal plane II at the central portion 50 of the spring. It appears that the projection 51 is housed within an opening formed within the mobile mesh which is linked to the hooking lever 23 and the movable tab 41 of the cover, this opening forming a counterform of the projection . This architecture makes it possible to block in rotation the central portion 50 of the spring 25 relative to this movable tab 41.

Les figures 21a et 21b illustrent ce même fermoir par une coupe au niveau d'une zone intermédiaire ressort 55 du ressort 25. On retrouve ainsi une portion de spire du ressort 25 qui entoure à jeu une barrette formant un axe d'articulation 24.The figures 21a and 21b illustrate this same clasp by a section at a spring intermediate zone 55 of the spring 25. There is thus a portion of turn of the spring 25 which surrounds clearance a bar forming a hinge pin 24.

Enfin, les figures 22a et 22b illustrent une coupe du fermoir au niveau d'une extrémité 57 du ressort 25. En remarque, l'architecture de cette solution est symétrique autour d'un plan médian et on pourrait ici considérer de manière identique l'une quelconque des deux parties latérales du fermoir. La saillie 59 coopère avec des ouvertures correspondantes agencées dans des pièces de bord solidaires de la partie fixe 40 du couvercle, ce qui permet de bloquer en rotation les deux extrémités du ressort 25.Finally, Figures 22a and 22b illustrate a section of the clasp at one end 57 of the spring 25. As a remark, the architecture of this solution is symmetrical about a median plane and one could consider here in an identical way any one of the two lateral parts of the clasp. The projection 59 cooperates with corresponding openings arranged in edge pieces integral with the fixed part 40 of the cover, which makes it possible to lock the two ends of the spring 25 in rotation.

En remarque, le montage de ce fermoir nécessite de monter et démonter l'axe d'articulation 24 et le ressort 25. Pour cela, les saillies 58, 59 agencées aux extrémités 56, 57 du ressort 25 permettent la traversée de l'ouverture de la maille mobile qui est solidaire du levier d'accrochage 23, qui reçoit la saillie 51 de la partie centrale du ressort 25, comme illustré par la figure 23. Les saillies 58, 59, 51 sont par exemple alignées dans ce mode de réalisation. De plus, les découpes traversantes 43 permettent le montage et démontage du couvercle du fermoir, comme dans le mode de réalisation précédent.Note, the mounting of this clasp requires to assemble and disassemble the hinge pin 24 and the spring 25. For this, the projections 58, 59 arranged at the ends 56, 57 of the spring 25 allow the passage of the opening of the mobile mesh which is secured to the hooking lever 23, which receives the projection 51 of the central portion of the spring 25, as illustrated by the figure 23 . The projections 58, 59, 51 are for example aligned in this embodiment. In addition, the through cuts 43 allow the assembly and disassembly of the lid of the clasp, as in the previous embodiment.

Le diamètre de la découpe circulaire de la partie centrale 50 du ressort 25 est inférieur au diamètre intérieur des spires des deux zones ressort 55, et inférieur ou égal au diamètre des découpes circulaires 52, 53 des extrémités 56, 57 du ressort 25. De plus, ce diamètre intérieur de la partie centrale 50 du ressort 25 pivote à moindre jeu sur l'axe d'articulation 24. De manière complémentaire, le diamètre extérieur (en faisant abstraction des saillies 51, 58, 59) de la partie centrale 50 du ressort 25, voire aussi des extrémités 56 ,57 (ou d'au moins une extrémité) du ressort 25, est supérieur au diamètre extérieur des spires des zones ressort 55 du ressort. Par cette construction, le guidage de la rotation du levier d'accrochage et de l'onglet mobile du couvercle est assuré de manière indépendante des fluctuations géométriques des spires de ses zones ressort.The diameter of the circular cutout of the central portion 50 of the spring 25 is smaller than the inner diameter of the turns of the two spring zones 55, and less than or equal to the diameter of the circular cutouts 52, 53 of the ends 56, 57 of the spring 25. Moreover, this inner diameter of the central portion 50 of the spring 25 pivots with less play on the hinge axis 24. In a complementary manner, the outer diameter (excluding the projections 51, 58, 59) of the central portion 50 of the spring 25, or even the ends 56, 57 (or at least one end) of the spring 25 is greater than the outer diameter of the turns of the spring zones 55 of the spring. By this construction, the guide of the rotation of the latching lever and the movable tab of the lid is provided independently of the geometric fluctuations of the turns of its spring zones.

Les figures 24 à 31 illustrent un fermoir selon un cinquième mode de réalisation de l'invention.The Figures 24 to 31 illustrate a clasp according to a fifth embodiment of the invention.

Ce fermoir diffère des réalisations précédentes en ce que le ressort de torsion n'est pas associé à un axe d'articulation distinct, mais remplit seul la fonction supplémentaire d'axe d'articulation. Les figures 24 à 26 illustrent ce quatrième mode de réalisation dans le cas d'un fermoir sans couvercle, proche de la réalisation selon le premier mode de réalisation.This clasp differs from the previous embodiments in that the torsion spring is not associated with a separate hinge axis, but fills only the additional function of hinge axis. The Figures 24 to 26 illustrate this fourth embodiment in the case of a clasp without cover, close to the embodiment according to the first embodiment.

Dans cette réalisation, un unique ressort 25 est utilisé, représenté par les figures 27 et 28. Ce ressort 25 comprend une partie centrale 35 hélicoïdale se composant de spires, disposée entre deux extrémités 36, 37. Chacune de ces extrémités comprend une forme sensiblement cylindrique, dont le pourtour comprend au moins une saillie, respectivement 38, 39. Chaque extrémité comprend de plus des portions cylindriques allongées 46, 47 qui remplissent la fonction de guidage radial. D'autres aspects de ce ressort sont détaillés ci-après.In this embodiment, a single spring 25 is used, represented by the Figures 27 and 28 . This spring 25 comprises a helical central part consisting of turns, disposed between two ends 36, 37. Each of these ends comprises a substantially cylindrical shape, the periphery of which comprises at least one projection, respectively 38, 39. Each end comprises more elongated cylindrical portions 46, 47 which fulfill the radial guide function. Other aspects of this jurisdiction are detailed below.

Les figures 29a et 29b illustrent ainsi une vue en coupe du fermoir selon un plan longitudinal I-I au niveau de la partie centrale du ressort 25. On retrouve ainsi une portion de spire du ressort 25 autour de laquelle pivote le levier d'accrochage 23 du fermoir.The Figures 29a and 29b and illustrate a sectional view of the clasp along a longitudinal plane II at the central portion of the spring 25. There is thus a portion of turn of the spring 25 around which pivots the hooking lever 23 of the clasp.

Les figures 31a et 31b montrent une vue en coupe du fermoir selon un plan longitudinal II-II selon le quatrième mode de réalisation au niveau d'une première extrémité 37 du ressort 25. La saillie 39 du ressort 25 coopère avec une ouverture correspondante agencée dans le levier d'accrochage 23, ce qui permet de bloquer en rotation cette extrémité du ressort 25.The Figures 31a and 31b show a sectional view of the clasp according to a longitudinal plane II-II according to the fourth embodiment at a first end 37 of the spring 25. The projection 39 of the spring 25 cooperates with a corresponding opening arranged in the engaging lever 23, which makes it possible to lock this end of the spring 25 in rotation.

Les figures 31a et 31b montrent une vue en coupe du fermoir selon un plan longitudinal III-III selon le cinquième mode de réalisation au niveau de la seconde extrémité 36 du ressort 25. La saillie 38 du ressort coopère avec une ouverture correspondante agencée dans un maillon de bord 22, ce qui permet de bloquer en rotation cette extrémité du ressort 25.The Figures 31a and 31b show a sectional view of the clasp along a longitudinal plane III-III according to the fifth embodiment at the second end 36 of the spring 25. The projection 38 of the spring cooperates with a corresponding opening arranged in an edge link 22, this which makes it possible to lock this end of the spring 25 in rotation.

Comme dans les réalisations précédentes, le ressort 25 comprend des surfaces extérieures de plus grand diamètre au niveau d'au moins une de ses extrémités, ce qui permet de former des surfaces de guidage du mouvement de pivotement, et rendre le mouvement indépendant du reste des fluctuations du ressort.As in the previous embodiments, the spring 25 comprises outer surfaces of larger diameter at least one of its ends, which makes it possible to form guide surfaces of the pivoting movement, and to make the movement independent of the rest of the fluctuations of the spring.

Les figures 32 à 38 illustrent un fermoir selon un cinquième mode de réalisation de l'invention.The Figures 32 to 38 illustrate a clasp according to a fifth embodiment of the invention.

Ce fermoir diffère de la réalisation précédente en ce qu'il utilise deux ressorts de torsion, qui restent non associés à un axe d'articulation distinct, mais remplissent seuls la fonction supplémentaire d'axe d'articulation. Les figures 32 à 34 illustrent ce cinquième mode de réalisation dans le cas d'un fermoir sans couvercle, proche de la réalisation selon le premier mode de réalisation et de la réalisation précédente.This clasp differs from the previous embodiment in that it uses two torsion springs, which remain unassociated with a separate hinge axis, but only fulfill the additional function of axis of articulation. The Figures 32 to 34 illustrate this fifth embodiment in the case of a clasp without cover, close to the embodiment according to the first embodiment and the previous embodiment.

Dans cette réalisation, l'unique ressort du mode de réalisation précédent est remplacé par deux ressorts 25, 25', représentés sur la figure 35. Chacun de ces ressorts 25, 25' comprend une partie centrale 35, 35' se composant de spires hélicoïdales, remplissant la fonction de « ressort », disposée entre deux extrémités 36, 37 ; 36', 37'. Chacune de ces extrémités comprend une forme sensiblement cylindrique, dont le pourtour comprend au moins une saillie, respectivement 38, 39, 38' (non visible), 39'. Les deux extrémités 36, 37' de respectivement les deux ressorts 25, 25', comprennent des extensions 66, 67' formant des moyens de liaison complémentaires, permettant la liaison des deux ressorts 25, 25'. Dans ce mode de réalisation, le premier ressort 25 comprend une extension 66 formant une saillie axiale prévue pour se loger dans un alésage de l'extension 67' du second ressort 25'. Cette liaison des deux ressorts est particulièrement visible sur la figure 34.In this embodiment, the single spring of the previous embodiment is replaced by two springs 25, 25 ', shown in FIG. figure 35 . Each of these springs 25, 25 'comprises a central portion 35, 35' consisting of helical turns, filling the function of "spring", disposed between two ends 36, 37; 36 ', 37'. Each of these ends comprises a substantially cylindrical shape, the periphery of which comprises at least one protrusion, respectively 38, 39, 38 '(not visible), 39'. The two ends 36, 37 'respectively of the two springs 25, 25', comprise extensions 66, 67 'forming complementary connecting means, allowing the connection of the two springs 25, 25'. In this embodiment, the first spring 25 comprises an extension 66 forming an axial projection intended to be housed in a bore of the extension 67 'of the second spring 25'. This connection of the two springs is particularly visible on the figure 34 .

Les figures 36a et 36b représentent une vue en coupe de ce fermoir selon un plan longitudinal I-I au niveau de sa partie centrale. Ce plan de coupe passe au niveau de l'extension 67' du second ressort 25. On s'aperçoit aussi que le maillon central 28 du fermoir entoure cette extension 67'.The Figures 36a and 36b represent a sectional view of this clasp along a longitudinal plane II at its central portion. This cutting plan passes at the level of the extension 67 'of the second spring 25. It is also seen that the central link 28 of the clasp surrounds this extension 67'.

Les figures 37a et 37b montrent une vue en coupe du fermoir selon un plan longitudinal II-II au niveau d'une première extrémité 36 du premier ressort 25. La saillie 38 du ressort 25 coopère avec une ouverture correspondante agencée dans le levier d'accrochage 23, ce qui permet de bloquer en rotation cette extrémité du ressort 25. De manière sensiblement symétrique, la saillie 39' du second ressort 25' est aussi logée dans une ouverture formant contre-forme de ce même levier d'accrochage 23.The figures 37a and 37b show a sectional view of the clasp along a longitudinal plane II-II at a first end 36 of the first spring 25. The projection 38 of the spring 25 cooperates with a corresponding opening arranged in the attachment lever 23, which allows to lock in rotation this end of the spring 25. In a substantially symmetrical manner, the projection 39 'of the second spring 25' is also housed in an aperture forming a counter-form of the same hooking lever 23.

Les figures 38a et 38b montrent une vue en coupe du fermoir au niveau de la seconde extrémité 37 du premier ressort 25. La saillie 39 du ressort coopère avec une ouverture correspondante agencée dans un maillon de bord 22, ce qui permet de bloquer en rotation cette extrémité du ressort 25. De manière sensiblement symétrique, la saillie 38' du second ressort 25' est aussi logée dans une ouverture formant contre-forme d'un maillon de bord 22 opposé.The Figures 38a and 38b show a sectional view of the clasp at the second end 37 of the first spring 25. The projection 39 of the spring cooperates with a corresponding opening arranged in an edge link 22, which makes it possible to lock this end of the spring 25 in rotation. In a substantially symmetrical manner, the projection 38 'of the second spring 25' is also housed in a counter-shaped opening of an opposite edge link 22.

Les figures 39 à 45 illustrent un fermoir selon un sixième mode de réalisation de l'invention. Celles-ci illustrent ce sixième mode de réalisation dans le cas d'un fermoir sans couvercle, proche de la réalisation selon le mode de réalisation précédent.The Figures 39 to 45 illustrate a clasp according to a sixth embodiment of the invention. These illustrate this sixth embodiment in the case of a clasp without cover, close to the embodiment according to the previous embodiment.

Ce fermoir se distingue de la réalisation précédente en ce qu'il utilise un seul ressort de torsion agencé différemment, qui remplit seul la fonction d'axe d'articulation. Dans cette réalisation, l'unique ressort 25, dont deux variantes de réalisation sont représentées sur les figures 42 et 43, comporte une partie centrale 35 se composant d'un fil de torsion, remplissant la fonction de « ressort », sur laquelle sont rapportées les première et seconde parties 36, 37. Par exemple, ces parties peuvent être rapportées par soudage, notamment par soudage laser, ou encore par brasage ou collage. Elles peuvent également être solidarisées au fil de torsion par écrasement de matière. A cet effet, des conformations géométriques, notamment des méplats 86, 87, sont prévues sur les parties 36 et 37 de manière à permettre un écrasement du fil de torsion à ses extrémités.This clasp differs from the previous embodiment in that it uses a single torsion spring arranged differently, which fills only the function of axis of articulation. In this embodiment, the single spring 25, two embodiments of which are shown on the Figures 42 and 43 , comprises a central part 35 consisting of a torsion wire, fulfilling the function of "spring", on which are reported the first and second parts 36, 37. For example, these parts can be reported by welding, especially by laser welding, or by soldering or gluing. They can also be secured to the twisting thread by crushing material. For this purpose, geometric conformations, including flats 86, 87, are provided on the parts 36 and 37 so as to allow crushing of the torsion wire at its ends.

La figure 42 illustre une première variante de réalisation du ressort au sein de laquelle la section du fil de torsion est circulaire. La section du fil de torsion présente par exemple un diamètre de l'ordre de 0.5 mm. La figure 43 illustre une deuxième variante de réalisation du ressort au sein de laquelle la section du fil de torsion est carrée. Bien entendu, cette section peut présenter toute sorte de géométrie adaptée de manière à générer un couple de rappel adéquat. La section du fil de torsion peut également être pleine ou creuse. Avantageusement, ce fil de torsion peut être usiné à partir d'un matériau ressort tel que celui connu par sa marque commerciale Nivaflex. Il pourrait également être réalisé en Phynox ou en tout autre alliage à base de cobalt. Ce fil de torsion pourrait également être usiné à partir d'un alliage à mémoire de forme tel que celui connu par sa marque commerciale Nitinol, ou encore en titane. Ce fil de torsion peut également être écroui.The figure 42 illustrates a first embodiment of the spring in which the section of the torsion wire is circular. The section of the torsion wire has for example a diameter of the order of 0.5 mm. The figure 43 illustrates a second embodiment of the spring in which the section of the torsion wire is square. Of course, this section may have any kind of adapted geometry so as to generate an adequate return torque. The section of the twist wire can also be solid or hollow. Advantageously, this twisting wire can be machined from a spring material such as that known by its trademark Nivaflex. It could also be made of Phynox or any other cobalt-based alloy. This twist wire could also be machined from a shape memory alloy such as that known by its trademark Nitinol, or titanium. This twist wire can also be hardened.

Les figures 44a et 44b représentent une vue en coupe du fermoir selon un plan longitudinal I-I au niveau de sa partie centrale. Ce plan de coupe passe au niveau d'une première partie 36 du ressort 25. Il apparaît que cette partie 36 est disposée de sorte que sa saillie 38 soit logée au sein d'une ouverture aménagée au sein du maillon central 28, cette ouverture formant une contre-forme de la saillie 38. Cette architecture permet de bloquer en rotation, c'est-à-dire dans les deux sens de rotation, la partie 36 du ressort 25 relativement au maillon central 28, et aussi relativement aux maillons de bord 22 du fermoir, ces derniers étant solidaires du maillon central 28 par un axe d'assemblage connexe.The Figures 44a and 44b are a sectional view of the clasp along a longitudinal plane II at its central portion. This cutting plane passes at a first portion 36 of the spring 25. It appears that this portion 36 is arranged so that its projection 38 is housed within an opening formed in the central link 28, this opening forming A counter-shape of the projection 38. This architecture makes it possible to block in rotation, that is to say in both directions of rotation, the portion 36 of the spring 25 relative to the central link 28, and also relative to the edge links. 22 of the clasp, the latter being secured to the central link 28 by an associated assembly axis.

Les figures 45a et 45b montrent une vue en coupe du fermoir selon un plan longitudinal II-II au niveau d'une seconde partie 37 du premier ressort 25. La saillie 39 du ressort 25 coopère avec une ouverture correspondante agencée dans le levier d'accrochage 23, cette ouverture formant une contre-forme de la saillie 39. Cette architecture permet de bloquer en rotation, c'est-à-dire dans les deux sens de rotation, la partie 37 du ressort 25 relativement au levier d'accrochage 23. Par cette construction, le guidage de la rotation du levier d'accrochage 23 est assuré par le diamètre extérieur des parties 36, 37 ou d'une portion des parties 36, 37 (en faisant abstraction des saillies 38, 39). Par ailleurs, les parties 36 et 37 mettent également en oeuvre l'axe de liaison entre les deux composants.The figures 45a and 45b show a sectional view of the clasp along a longitudinal plane II-II at a second portion 37 of the first spring 25. The projection 39 of the spring 25 cooperates with a corresponding opening arranged in the attachment lever 23, this opening forming a counter-form of the projection 39. This architecture makes it possible to block in rotation, that is to say in both directions of rotation, the portion 37 of the spring 25 relative to the engaging lever 23. By this construction, the Guiding the rotation of the latching lever 23 is provided by the outer diameter of the portions 36, 37 or a portion of the portions 36, 37 (disregarding the projections 38, 39). Furthermore, the parts 36 and 37 also implement the connecting axis between the two components.

Finalement, dans tous les modes de réalisation, au moins un ressort de torsion est utilisé, pour la mise en oeuvre d'une articulation élastique entre deux composants d'un mécanisme horloger, ce qui présente l'avantage de minimiser l'encombrement par rapport aux solutions de l'état de la technique. Ce ressort peut par exemple comporter des spires hélicoïdales ou encore un, voire plusieurs, fil de torsion.Finally, in all the embodiments, at least one torsion spring is used, for the implementation of an elastic articulation between two components of a clock mechanism, which has the advantage of minimizing the bulk compared with to the solutions of the state of the art. This spring may for example comprise helical turns or one or more torsion wire.

Dans tous les modes de réalisation, un ressort présente au moins une saillie qui est prévue pour s'engager au sein d'une contre-forme sensiblement complémentaire, voire complémentaire, pour bloquer angulairement la zone correspondante du ressort au composant auquel elle est liée, c'est à dire bloquer sa rotation, dans les deux sens de rotation. Comme mentionné précédemment, dans une variante de réalisation, cette contre-forme peut autoriser un certain débattement angulaire de la saillie. Dans cette variante, la contre-forme définit donc deux butées qui bloquent chacune une rotation dans un sens donné du ressort, qui limitent la rotation dans un certain débattement angulaire entre les deux butées. Cette approche permet d'indexer angulairement les deux composants articulés.In all the embodiments, a spring has at least one projection which is designed to engage in a counter-shape that is substantially complementary, or even complementary, to angularly block the corresponding zone of the spring to the component to which it is linked. that is blocking its rotation, in both directions of rotation. As mentioned above, in an alternative embodiment, this counter-form may allow a certain angular displacement of the projection. In this variant, the counterform therefore defines two stops which each block a rotation in a given direction of the spring, which limit the rotation in a certain angular displacement between the two stops. This approach makes it possible to angularly index the two articulated components.

De plus, des zones particulières du ressort sont aussi prévues pour former des surfaces de guidage, qui mettent en oeuvre la fonction de guidage du mouvement de rotation des deux composants horlogers, pour s'affranchir des défauts, dispersions, fluctuations de forme des autres parties du ressort, notamment les parties comprenant les spires dans le cas d'un ressort hélicoïdal de torsion, ou comprenant un fil de torsion dans un autre cas, cette ou ces autre(s) partie(s) remplissant la fonction élastique. Pour cela, ces zones particulières se présentent avantageusement sous des formes à base cylindrique avec des diamètres différents pour une liaison à moindre jeu avec les composants horlogers. En remarque, une telle liaison à moindre jeu signifie donc que le jeu est suffisamment faible pour que les deux composants en liaison puissent être mobiles en rotation l'un par rapport à l'autre, mais avec une mobilité très réduite dans les autres directions, pour assurer une fonction de guidage du mouvement de rotation. De préférence, ce jeu sera inférieur à 0,15 mm, voire inférieur à 0,1 mm, par exemple autour d'un jeu nominal d'environ 0,07 mm. Ainsi, si la surface de guidage du ressort et la surface correspondante du composant horloger en liaison à moindre jeu sont toutes deux sensiblement cylindriques de diamètres respectifs D1 et D2, il sera préférentiellement choisi |D1-D2| ≤ 0,15 mm ou 0,1 mm.In addition, particular areas of the spring are also provided to form guide surfaces, which implement the function of guiding the rotational movement of the two watch components, to overcome the defects, dispersions, shape fluctuations of other parts. of the spring, in particular the parts comprising the turns in the case of a helical torsion spring, or comprising a torsion wire in another case, this or these other part (s) fulfilling the elastic function. For this, these particular areas are advantageously in cylindrical base shapes with different diameters for a connection with less play with the watch components. As a remark, such a link with less game means that the game is low enough so that the two components in connection can be rotated relative to each other, but with a very low mobility in other directions, to provide a function of guiding the rotational movement. Preferably, this clearance will be less than 0.15 mm, or even less than 0.1 mm, for example around a nominal clearance of about 0.07 mm. Thus, if the guiding surface of the spring and the corresponding surface of the watch component in connection with a smaller clearance are both substantially cylindrical with respective diameters D1 and D2, it will preferably be chosen | D1-D2 | ≤ 0.15 mm or 0.1 mm.

Naturellement, certains éléments des solutions décrites précédemment peuvent en variante se trouver sous une autre forme. Notamment, comme cela a été vu, un ou plusieurs ressorts de torsion peuvent être utilisés. Dans le cas de plusieurs ressorts, ils peuvent être indépendants ou assemblés. D'autre part, certaines zones ont été conçues pour bloquer angulairement et/ou guider le mouvement de rotation des composants horlogers : ces zones ont été positionnées vers les extrémités et/ou au centre du ressort. Elles pourraient en variante se trouver à tout autre emplacement du ressort. De plus, au moins une saillie a été utilisée pour former un élément de blocage angulaire. En variante, toute saillie radiale ou longitudinale, une denture, un méplat, un lamage, et/ou un alésage, etc., peuvent être utilisés. De plus, comme cela a été explicité précédemment, le blocage en rotation doit être interprété comme un agencement qui permet soit de bloquer totalement toute rotation, soit qui permet de limiter cette rotation par deux butées qui empêchent chacune une rotation dans un certain sens et finalement qui limitent le degré de liberté dans un certain débattement angulaire entre les deux butées. Ce débattement angulaire est de préférence faible, inférieur ou égal à 20 degrés, voire 10 degrés.Of course, some elements of the previously described solutions may alternatively be in another form. In particular, as has been seen, one or more torsion springs can be used. In the case of several springs, they can be independent or assembled. On the other hand, certain zones have been designed to angularly block and / or guide the rotational movement of the watch components: these zones have been positioned towards the ends and / or at the center of the spring. They could alternatively be at any other spring location. In addition, at least one protrusion has been used to form an angular locking element. As a variant, any radial or longitudinal projection, a Toothing, a flat, a counterbore, and / or a bore, etc., may be used. In addition, as explained above, the locking in rotation must be interpreted as an arrangement that allows to completely block any rotation, or that limits this rotation by two stops that each prevent rotation in a certain direction and finally which limit the degree of freedom in a certain angular displacement between the two stops. This angular deflection is preferably low, less than or equal to 20 degrees, or even 10 degrees.

De plus, comme cela a été vu, ce ou ces ressort(s) de torsion sont avantageusement disposés le long de l'axe de rotation des deux composants horlogers. Ils peuvent être associés à un axe d'articulation existant physiquement sous la forme d'un axe ou d'une barrette ou sans aucun autre élément, formant alors eux-mêmes l'axe d'articulation physique des composants articulés. En variante, cet axe de rotation est formé par exemple par un ou plusieurs ressort(s) de l'agencement, sans ajout d'un axe physique distinct, l'axe de rotation ou axe de liaison entre les deux composants étant alors non directement matérialisé.In addition, as has been seen, this or these torsion spring (s) are advantageously arranged along the axis of rotation of the two watch components. They can be associated with a hinge axis existing physically in the form of an axis or a bar or without any other element, then themselves forming the axis of physical articulation of the articulated components. Alternatively, this axis of rotation is formed for example by one or more spring (s) of the arrangement, without adding a separate physical axis, the axis of rotation or axis of connection between the two components being then not directly materialized.

L'invention a été illustrée à partir d'un fermoir de bracelet associé à une montre-bracelet, qui est d'ailleurs aussi concernée en tant que telle par cette invention, et plus précisément au niveau du mécanisme de verrouillage de ce fermoir, entre un élément mobile comme un levier ou une came mettant en oeuvre le verrouillage et déverrouillage et un autre composant distinct fixe du fermoir. En variante, ce principe peut être implémenté pour toute liaison élastique articulée entre deux composants horlogers, que ce mouvement soit une pure rotation ou plus complexe, comme une rotation combinée à un autre déplacement.The invention has been illustrated from a bracelet clasp associated with a wristwatch, which is also also concerned as such by this invention, and more precisely at the locking mechanism of this clasp, between a movable element such as a lever or a cam implementing the locking and unlocking and another separate fixed component of the clasp. As a variant, this principle can be implemented for any elastic link articulated between two watch components, whether this movement is a pure rotation or more complex, such as a rotation combined with another displacement.

Par exemple, il peut ainsi être implémenté entre deux mailles d'un bracelet, comme cela est illustré schématiquement par la figure 46, qui montre deux mailles 71, 72 de bracelet articulées par deux ressorts de torsion 75, similaires à ceux représentés par les figures 27 et 28. Une telle solution permet de pré-orienter angulairement les différentes mailles d'un bracelet élastique, qui peut alors être préformé à la géométrie du poignet de son porteur.For example, it can be implemented between two meshes of a bracelet, as schematically illustrated by the figure 46 , which shows two bracelet stitches 71, 72 articulated by two torsion springs 75, similar to those represented by the Figures 27 and 28 . Such a solution makes it possible to angularly pre-orient the various stitches of an elastic bracelet, which can then be preformed to the geometry of the wrist of its wearer.

Selon une autre variante, le principe de l'invention peut être implémenté entre deux composants quelconques d'une pièce d'horlogerie. Naturellement, de nombreux autres modes de réalisation de l'invention peuvent être facilement déduits par la combinaison des différentes réalisations illustrées précédemment, ou en intégrant n'importe quel ressort décrit précédemment entre deux composants horlogers articulés.According to another variant, the principle of the invention can be implemented between any two components of a timepiece. Naturally, many other embodiments of the invention can be easily deduced by the combination of the different embodiments illustrated above, or by integrating any previously described spring between two articulated watch components.

Un problème technique se pose pour fabriquer de manière optimale des ressorts comportant une zone formée de spires hélicoïdales utilisés pour des implémentations de l'invention.A technical problem arises to optimally manufacture springs comprising an area formed of helical turns used for implementations of the invention.

Une première solution consiste à usiner un matériau ressort tel que celui connu par sa marque commerciale Nivaflex. Des fentes de l'ordre de 0,4 mm peuvent alors être réalisées, par exemple par une découpe laser.A first solution consists in machining a spring material such as that known by its trademark Nivaflex. Slots of the order of 0.4 mm can then be made, for example by laser cutting.

Une seconde solution consiste en une fabrication d'un ressort en plusieurs parties. La figure 47 illustre à titre d'exemple la réalisation d'un ressort 25 particulier à partir de trois parties distinctes. Une première étape de ce procédé comprend donc la fabrication de plusieurs parties distinctes du ressort, notamment en séparant la zone remplissant la fonction élastique des zones de blocage en rotation et/ou guidage. Ainsi, en reprenant l'exemple illustré par la figure 47, une partie centrale 35 est obtenue à partir d'un fil enroulé préalablement écroui. Ensuite, les deux extrémités 36, 37 sont usinées à partir d'un matériau plus conventionnel, comme un acier inoxydable. Une seconde étape consiste alors en l'assemblage des parties distinctes. Cet assemblage peut par exemple se faire par soudure laser. Pour minimiser les sollicitations lors de ces soudures, les extrémités à souder de chacune de ces parties distinctes peuvent présenter une découpe en escalier 81. Cette fabrication utilise un fil de section de préférence carrée ou rectangle, avec un espacement entre les spires choisis pour obtenir le couple de rappel recherché. Ce procédé de fabrication permet notamment de générer un contact entre les spires du ressort de la partie centrale 35 pour atteindre un couple de torsion maximum.A second solution consists in making a spring in several parts. The figure 47 illustrating by way of example the making of a particular spring from three distinct parts. A first step of this method therefore comprises the manufacture of several distinct parts of the spring, in particular by separating the zone filling the elastic function of the locking zones in rotation and / or guiding. So, taking again the example illustrated by the figure 47 a central portion 35 is obtained from a wound wire previously hardened. Then, both ends 36, 37 are machined from a more conventional material, such as stainless steel. A second step then consists in assembling the parts distinct. This assembly can for example be done by laser welding. To minimize the stresses during these welds, the ends to be welded of each of these distinct parts may have a cut-out staircase 81. This manufacture uses a wire of preferably square or rectangle section, with a spacing between the turns chosen to obtain the recall couple wanted. This manufacturing method makes it possible in particular to generate contact between the turns of the spring of the central portion 35 to reach a maximum torque.
