Description

Objet de l'inventionObject of the invention

La présente invention se rapporte au domaine des bracelets amovibles qui permettent de fixer un objet tel une montre au poignet.The present invention relates to the field of removable bracelets which make it possible to attach an object such as a watch to the wrist.

Arrière-plan technologiqueTechnological background

Les bracelets et en particulier les bracelets de montre sont des liens réalisés en différents types de matériaux - cuir, plastique, métal, parfois même en tissu - qui permettent de fixer un objet tel une montre, mais également de manière plus générale un bijou de forme quelconque, au poignet de la personne qui souhaite le porter. Ces bracelets s'adaptent au poignet de la personne et sont habituellement directement fixés aux cornes de la boîte de montre par l'entremise de petites tiges métalliques appelées barrettes qui vont se fixer dans un logement adéquat ménagé dans les cornes.Bracelets and in particular watch bracelets are links made of different types of materials - leather, plastic, metal, sometimes even fabric - which allow an object such as a watch to be fixed, but also more generally a shaped jewel. any, on the wrist of the person who wishes to wear it. These bracelets adapt to the wrist of the person and are usually directly attached to the horns of the watch case by means of small metal rods called bars which will be fixed in a suitable housing made in the horns.

En cas d'endommagement ou tout simplement pour des raisons esthétiques, l'utilisateur peut être amené à changer plusieurs fois de bracelets sur la durée de vie de sa montre. A cet effet, il existe des dispositifs de fixation qui permettent plus ou moins facilement de changer de bracelets sans l'aide d'outils spécifiques. Cependant, même si le changement de bracelets ne requière pas d'outils spécifiques et peut dès lors être effectué par l'utilisateur, la manipulation du dispositif de fixation peut être mal aisée et/ou le dispositif peut présenter des organes de commande non seulement visibles depuis l'extérieur du bracelet mais également susceptibles d'être accrochés. Ainsi, par exemple le document EP 2 766 587 divulgue un dispositif de fixation présentant ces désavantages. Le dispositif comprend deux pivots à ressorts dont un est muni d'un doigt faisant saillie hors du bracelet, le déplacement du doigt permettant de rétracter le pivot dans la barrette.In the event of damage or simply for aesthetic reasons, the user may have to change straps several times over the life of his watch. For this purpose, there are fixing devices which make it more or less easy to change bracelets without using specific tools. However, even if the change of bracelets does not require specific tools and can therefore be carried out by the user, the handling of the fastening device may be difficult and / or the device may have control members that are not only visible. from the outside of the bracelet but also capable of being hung. Thus, for example the document EP 2,766,587 discloses a fastening device having these disadvantages. The device comprises two spring-loaded pivots, one of which is provided with a finger projecting out of the bracelet, the movement of the finger making it possible to retract the pivot into the bar.

On connaît également du document CH 694393 un dispositif de fixation de l'extrémité d'un bracelet ou boîtier d'une montre.We also know from the document CH 694393 a device for fixing the end of a bracelet or watch case.

Résumé de l'inventionSummary of the invention

Pour remédier aux désavantages précités, la présente invention a pour objet principal de proposer un nouveau dispositif de fixation permettant une manipulation aisée par l'utilisateur et pouvant être disposé au sein du bracelet de manière invisible. La présente invention a également pour objet de proposer un dispositif de fixation qui soit robuste, les barrettes de fixation étant de manière générale relativement fragiles.To remedy the aforementioned drawbacks, the main object of the present invention is to provide a novel fixing device allowing easy handling by the user and which can be placed within the bracelet in an invisible manner. Another object of the present invention is to provide a fastening device which is robust, the fastening bars generally being relatively fragile.

A cet effet, la présente invention propose un dispositif de fixation muni d'un organe de commande destiné après insertion au sein du bracelet à se déplacer verticalement par rapport au bracelet. Dans cette configuration, le dispositif de fixation et plus particulièrement l'organe de commande peut être entièrement noyé au sein du bracelet et actionné en jouant sur la souplesse du matériau qui recouvre l'organe de commande.To this end, the present invention proposes a fixing device provided with a control member intended, after insertion within the bracelet, to move vertically relative to the bracelet. In this configuration, the fixing device and more particularly the control member can be completely embedded within the bracelet and actuated by playing on the flexibility of the material which covers the control member.

L'organe de commande présente pour autre caractéristique d'être déporté par rapport à l'axe de coulissement des deux tiges formant la barrette de fixation, ce qui permet de gagner en robustesse et en précision de guidage par rapport à une configuration où l'organe de commande serait positionné sur l'axe de coulissement des tiges.Another characteristic of the control member is that it is offset relative to the sliding axis of the two rods forming the fixing bar, which makes it possible to gain in robustness and in guiding precision compared to a configuration where the control member would be positioned on the sliding axis of the rods.

L'organe de commande étant déporté par rapport à l'axe de coulissement des tiges, le dispositif de fixation est muni d'éléments de liaison entre l'organe de commande et la barrette de fixation permettant de transformer le mouvement de translation verticale de l'organe de commande en un mouvement de coulissement latéral de la barrette entre une position d'engagement et une position rétractée où la barrette est désolidarisée de l'objet auquel elle est fixée.The control member being offset relative to the axis of sliding of the rods, the fixing device is provided with connecting elements between the control member and the fixing bar making it possible to transform the vertical translational movement of the 'control member in a lateral sliding movement of the bar between an engagement position and a retracted position where the bar is detached from the object to which it is attached.

Avantageusement, les éléments de liaison comportent deux bras articulés autour d'un axe disposé à une extrémité proximale desdits bras, les deux tiges étant respectivement liées à l'extrémité distale des bras articulés via des biellettes. L'organe de commande et les bras articulés sont configurés pour induire un mouvement d'écartement des bras autour de l'axe menant au rapprochement de leurs extrémités distales qui sont liées aux deux tiges, plaçant ainsi lesdites tiges en position rétractée.Advantageously, the connecting elements comprise two arms articulated around an axis arranged at a proximal end of said arms, the two rods being respectively connected to the distal end of the articulated arms via links. The control member and the articulated arms are configured to induce a movement of separation of the arms around the axis leading to the approach of their distal ends which are linked to the two rods, thus placing said rods in the retracted position.

Autrement dit, les éléments de liaison comportent successivement entre l'organe de commande et les tiges :

  • deux bras articulés à une extrémité autour d'un axe vertical, dit de pivotement, les bras étant disposés autour de l'organe de commande de manière symétrique par rapport à une ligne reliant ledit axe de pivotement et l'axe de translation de l'organe de commande,
  • deux biellettes montées chacune pivotante sur l'autre extrémité desdits bras et solidaires respectivement des tiges.
In other words, the connecting elements comprise successively between the control member and the rods:
  • two arms articulated at one end about a vertical axis, called a pivot axis, the arms being arranged around the control member symmetrically with respect to a line connecting said pivot axis and the translation axis of the control unit,
  • two rods each mounted to pivot on the other end of said arms and respectively secured to the rods.

En utilisation, le pivotement des bras suite à l'actionnement de l'organe de commande entraîne un déplacement latéral des biellettes et par là-même un déplacement des tiges.In use, the pivoting of the arms following actuation of the control member causes a lateral displacement of the links and thereby a displacement of the rods.

D'autres avantages ressortiront des caractéristiques exprimées dans les revendications, de la description détaillée de l'invention illustrée ci-après à l'aide des dessins annexés donnés à titre d'exemples nullement limitatifs.Other advantages will emerge from the characteristics expressed in the claims, from the detailed description of the invention illustrated below with the aid of the appended drawings given by way of non-limiting examples.

Description détaillée de l'inventionDetailed description of the invention

Le dispositif de fixation 10 selon l'invention représenté aux figures 1 à 5 est destiné à être disposé de manière invisible à l'extrémité d'un bracelet, tel qu'un bracelet de montre ou de bijou. Il est plus particulièrement illustré à la figure 6 dans le cadre d'une fixation d'un bracelet 100 à une boîte de montre 200 munie de cornes 21,22 comprenant des trous borgnes 23,24 ou traversant pour le logement de la barrette du dispositif de fixation. A l'inverse, selon une autre forme d'exécution de l'invention, on peut envisager un entre-corne à pivot auquel cas la barrette présentera à ses extrémités des trous permettant d'accueillir les pivots.The fixing device 10 according to the invention shown in figures 1 to 5 is intended to be placed invisibly at the end of a bracelet, such as a watch or jewelry bracelet. It is more particularly illustrated at the figure 6 in the context of fixing a bracelet 100 to a watch case 200 provided with lugs 21, 22 comprising blind holes 23, 24 or through for housing the bar of the fixing device. Conversely, according to another embodiment of the invention, it is possible to envisage a pivot lug in which case the bar will have holes at its ends making it possible to accommodate the pivots.

Le dispositif de fixation 10 selon l'invention peut adopter deux positions représentées aux figures 1 et 4 avec respectivement une position de repos, qu'on peut également qualifier de position d'engagement, correspondant à la position dans laquelle le bracelet est fixé à la boîte de montre et une position rétractée dans laquelle le bracelet est désolidarisé de la boîte de montre.The fixing device 10 according to the invention can adopt two positions shown in figures 1 and 4 with respectively a rest position, which can also be qualified as an engagement position, corresponding to the position in which the bracelet is fixed to the watch case and a retracted position in which the bracelet is detached from the watch case.

Le dispositif de fixation 10 selon l'invention comporte une plaque de support 14 sur laquelle est monté le mécanisme permettant de permuter d'une position à une autre. Cette plaque 14 est formée d'une base 14a surmontée de plusieurs axes 11,17 sur lesquels des éléments du mécanisme sont montés mobiles (figure 2). La plaque 14 est ainsi munie d'un axe 17 perpendiculaire au plan de la base 14a sur lequel est monté mobile en translation un organe de commande, à savoir un bouton poussoir 1, qui permet d'actionner le mécanisme et plus précisément de déplacer en translation deux tiges 4',4" faisant office de barrette rétractable.The fixing device 10 according to the invention comprises a support plate 14 on which is mounted the mechanism making it possible to switch from one position to another. This plate 14 is formed by a base 14a surmounted by several pins 11,17 on which elements of the mechanism are movably mounted ( figure 2 ). The plate 14 is thus provided an axis 17 perpendicular to the plane of the base 14a on which a control member is mounted movably in translation, namely a push button 1, which makes it possible to actuate the mechanism and more precisely to move in translation two rods 4 ', 4 "acting as a retractable bar.

Ces deux tiges 4',4" sont disposées sur un même axe sur lequel elles coulissent en translation (figure 1). Elles sont liées par un ressort 2 maintenant les tiges 4',4" en position de repos en l'absence d'une sollicitation du bouton poussoir par un utilisateur. La translation des tiges 4',4" selon leur axe est assurée par des parois de guidage 3 solidaires de la plaque de support 14 et réparties le long de l'axe de part et d'autre de chaque tige 4',4" et du ressort 2 avec, dans l'exemple illustré, trois paires de parois 3 respectivement disposées aux extrémités et au centre de la plaque le long de cette axe.These two rods 4 ', 4 "are placed on the same axis on which they slide in translation ( figure 1 ). They are linked by a spring 2 maintaining the rods 4 ', 4 "in the rest position in the absence of a push button request by a user. The translation of the rods 4', 4" along their axis is ensured by guide walls 3 integral with the support plate 14 and distributed along the axis on either side of each rod 4 ', 4 "and of the spring 2 with, in the example illustrated, three pairs of walls 3 respectively arranged at the ends and at the center of the plate along this axis.

Selon l'invention, le bouton poussoir 1 n'est pas disposé dans l'axe des tiges mais déporté par rapport à cet axe. Dès lors, le déplacement des deux tiges 4',4" est lié au déplacement du bouton poussoir 1 par l'intermédiaire de deux bras 5',5" respectivement articulés sur des biellettes de liaison 6',6" elles-mêmes solidaires des tiges 4',4" par l'entremise de doigts 15',15" faisant saillie sur chaque tige 4',4".According to the invention, the push button 1 is not arranged in the axis of the rods but offset with respect to this axis. Therefore, the movement of the two rods 4 ', 4 "is linked to the movement of the push button 1 by means of two arms 5', 5" respectively articulated on connecting rods 6 ', 6 "themselves integral with the rods 4 ', 4 "through fingers 15', 15" projecting on each rod 4 ', 4 ".

Les deux bras 5',5" sont montés pivotants sur un axe vertical 11 formé dans la plaque de support 14 et visible entre autres aux figures 1 et 2. Les bras 5',5" sont disposés de manière symétrique par rapport à la ligne formée par les axes 11 et 17 alignés dans une direction perpendiculaire à l'axe des tiges 4',4". Les bras 5',5" se chevauchent sur l'axe 11 avec respectivement un bras 5" en position inférieure et un bras 5' en position supérieure par rapport au plan de la plaque de support. Ils contournent respectivement l'organe de commande 1 avant de se croiser en un point 12 également aligné sur la ligne formée par les axes 11 et 17 et diamétralement opposé par rapport à l'axe 11. Comme détaillé à la figure 5, chaque bras 5',5" comporte une première portion courbe, référencée a, épousant sensiblement la forme du bouton poussoir 1, et s'étendant sensiblement entre l'axe 11 et le point de croisement 12. Cette première portion courbe a est suivie d'une seconde portion rectiligne, référencée b, s'étendant sensiblement depuis le point de croisement 12 jusqu'aux chevilles 9',9" assurant la liaison en rotation entre les bras 5',5" et les biellettes 6',6". Dans l'exemple illustré, le bras en position inférieure 5" contourne le bouton poussoir 1 par la droite et s'étend ensuite vers la gauche pour commander le déplacement de la tige 4" correspondante. Par symétrie, le bras 5' en position supérieure contourne le bouton poussoir 1 par la gauche et s'étend vers la droite pour commander le déplacement de la tige 4' correspondante. Dans l'exemple illustré, les bras présentent sur les flancs intérieurs de leur portion courbe une paroi inclinée sur laquelle est destinée à coulisser les flancs latéraux du bouton poussoir de forme tronconique (figure 3). Alternativement la paroi inclinée pourrait être remplacée par une surface arrondie pour diminuer la surface de frottement. En outre, chaque bras 5',5" comporte une partie en surépaisseur, référencée c et visible à la figure 5, disposée sur sa portion courbe a et permettant de reprendre la différence de hauteur dans les zones où les bras ne sont pas superposés et dès lors d'assurer un déplacement symétrique des deux bras lors de l'actionnement du bouton poussoir. Plus précisément, le bras 5" en position inférieure sur l'axe 11 comporte une surépaisseur 5"c se dressant dans la direction opposée à la plaque de support 14 tandis que le bras 5' en position supérieure comporte une surépaisseur 5'c s'étendant en direction de la plaque de support 14. Ces surépaisseurs sont agencées de manière à ne pas entraver le déplacement des bras lors du pivotement.The two arms 5 ', 5 "are mounted to pivot on a vertical axis 11 formed in the support plate 14 and visible among others to figures 1 and 2 . The arms 5 ', 5 "are arranged symmetrically with respect to the line formed by the axes 11 and 17 aligned in a direction perpendicular to the axis of the rods 4', 4". The arms 5 ', 5 "overlap on the axis 11 with respectively an arm 5" in the lower position and an arm 5' in the upper position relative to the plane of the support plate. They respectively bypass the control member 1 before crossing at a point 12 also aligned on the line formed by the axes 11 and 17 and diametrically opposite with respect to the axis 11. As detailed in figure 5 , each arm 5 ', 5 "comprises a first curved portion, referenced a, substantially following the shape of the push button 1, and extending substantially between the axis 11 and the crossing point 12. This first curved portion a is followed by 'a second rectilinear portion, referenced b, extending substantially from the crossing point 12 to the pins 9', 9 "ensuring the rotational connection between the arms 5 ', 5" and the rods 6', 6 ". In the example illustrated, the arm in the lower position 5 "bypasses the push button 1 from the right and then extends to the left to control the movement of the corresponding rod 4". By symmetry, the arm 5 'in the upper position bypasses the push button 1 from the left and extends to the right to control the movement of the corresponding rod 4'. In the example illustrated, the arms have on the inner flanks of their curved portion an inclined wall on which the lateral flanks of the frustoconical pushbutton are intended to slide ( figure 3 ). Alternatively, the inclined wall could be replaced by a rounded surface to reduce the friction surface. In addition, each arm 5 ′, 5 "comprises a part with increased thickness, referenced c and visible at figure 5 , arranged on its curved portion a and making it possible to take up the difference in height in the zones where the arms are not superimposed and therefore to ensure a symmetrical movement of the two arms when the push button is actuated. More precisely, the arm 5 "in the lower position on the axis 11 has an extra thickness 5" c rising in the direction opposite to the support plate 14 while the arm 5 'in the upper position has an extra thickness 5' c s' extending in the direction of the support plate 14. These extra thicknesses are arranged so as not to hinder the movement of the arms during the pivoting.

Les bras 5',5" sont fixés aux biellettes 6',6" via les chevilles 9',9" permettant un mouvement relatif en rotation entre les bras 5',5" et les biellettes 6',6". A cet effet, les chevilles 9',9" coulissent dans des lumières 18',18" ménagées dans la plaque de support 14 en arcs de cercle centrés sur l'axe 11.The arms 5 ', 5 "are fixed to the rods 6', 6" via the pins 9 ', 9 "allowing relative rotational movement between the arms 5', 5" and the rods 6 ', 6 ". For this purpose , the 9 ', 9 "pegs slide in lights 18 ', 18 "formed in the support plate 14 in arcs of a circle centered on the axis 11.

Les biellettes de liaison 6',6" sont des pièces planes, de forme oblongue dans l'exemple illustré, ayant une épaisseur sensiblement égale à celle des bras. Au sein de chaque biellette 6',6", une lumière 16',16" également de forme oblongue est ménagée. Au sein de cette lumière le doigt 15',15" solidaire des tiges 4',4" y est guidé. Lors de leur déplacement, les biellettes de liaisons 6',6" sont maintenues perpendiculaires à l'axe des tiges 4',4" grâce à des parois rigides 13',13" ménagées dans les tiges 4',4" et entre lesquelles les biellettes 6',6" coulissent.The connecting rods 6 ', 6 "are flat parts, oblong in the example illustrated, having a thickness substantially equal to that of the arms. Within each rod 6', 6", a slot 16 ', 16 "also oblong in shape is provided. Within this slot the finger 15 ', 15" integral with the rods 4', 4 "is guided therein. During their movement, the connecting rods 6 ', 6" are kept perpendicular to the axis of the rods 4 ', 4 "by virtue of rigid walls 13', 13" formed in the rods 4 ', 4 "and between which the rods 6', 6" slide.

Comme montré à la figure 1, les tiges 4',4" et les biellettes 6',6" sont agencées différemment selon la position du bras 5',5" auquel elles sont reliées. Pour le bras 5" en position inférieure, la biellette 6" se positionne au-dessus du bras. Plus précisément, le bras 5" se positionne entre la lumière 18" et la biellette 6" avec le doigt 15" de la tige 4" tournés côté opposé à la plaque 14. Inversement, pour le bras 5' en position supérieure, la biellette 6' se positionne en dessous du bras, c.à.d. entre la lumière 18' et le bras 5' avec le doigt 15' de la tige 4' tournés vers la plaque de support 14.As shown in figure 1 , the rods 4 ', 4 "and the rods 6', 6" are arranged differently depending on the position of the arm 5 ', 5 "to which they are connected. For the arm 5" in the lower position, the rod 6 "is positioned at the -above the arm. More precisely, the arm 5 "is positioned between the slot 18" and the rod 6 "with the finger 15" of the rod 4 "turned to the opposite side to the plate 14. Conversely, for the arm 5 'in upper position, the rod 6 'is positioned below the arm, i.e. between the lumen 18 'and the arm 5' with the finger 15 'of the rod 4' facing the support plate 14.

Comme détaillé dans l'exemple de réalisation illustré à la figure 5, chaque tige 4',4" comporte une extrémité cylindrique 4'a,4"a destinée à se loger dans les trous ménagés dans les cornes de la boîte de montre. A la suite de la portion cylindrique, la tige 4',4" comporte une portion tronconique 4'b,4"b s'évasant vers une portion en U 4'c,4"c au sein de laquelle coulisse la biellette 6',6" correspondante avec les parois 13',13" du U assurant la fonction de guidage de la biellette. Cette portion comprend le doigt 15',15" se dressant dans la partie évidée du U. A la suite de la portion en U, la tige 4',4" comporte une seconde portion cylindrique 4'd,4"d autour de laquelle le ressort 2 est enroulé. Cette portion présente un diamètre inférieur à la hauteur de la paroi 13,13" de manière à ce que cette dernière forme un épaulement sur lequel le ressort 2 prend appui. Il va de soi que d'autres géométries des tiges 4', 4" pourraient être envisagées dès que lors qu'elles comportent une portion d'extrémité pouvant coopérer avec les trous de barrettes ménagés dans l'entre cornes d'une boite de montre. On pourrait même envisager dans une variante que les tiges 4', 4" soient réalisées en une seule pièce comprenant une partie médiane formant un ressort.As detailed in the exemplary embodiment illustrated in figure 5 , each rod 4 ', 4 "has a cylindrical end 4'a, 4" a intended to be housed in the holes made in the horns of the watch case. Following the cylindrical portion, the rod 4 ', 4 "comprises a frustoconical portion 4'b, 4" b widening towards a U-shaped portion 4'c, 4 "c within which the connecting rod 6' slides. , 6 "corresponding with the walls 13 ', 13" of the U ensuring the function of guiding the rod. This portion comprises the finger 15', 15 "rising in the recessed part of the U. Following the U-shaped portion , the rod 4 ', 4 "comprises a second cylindrical portion 4'd, 4" d around which the spring 2 is wound. This portion has a diameter less than the height of the wall 13.13 "so that the latter forms a shoulder on which the spring 2 is supported. It goes without saying that other geometries of the rods 4 ', 4 "could be envisaged as soon as they comprise an end portion which can cooperate with the holes in the bars formed in the between lugs of a watch case. In a variant, it could even be envisaged that the rods 4 ′, 4 "are made in a single piece comprising a middle part forming a spring.

Idéalement, les tiges sont réalisées en métal avec un revêtement antifriction aux extrémités destinées à se loger dans la boîte de montre afin d'éviter les rayures à l'intérieur des cornes. Ce revêtement peut notamment être en PTFE, ou en polyuréthane chargé d'une huile de perfluoropolyéthers (PFPE).Ideally, the rods are made of metal with an anti-friction coating at the ends intended to be housed in the watch case to avoid scratches inside the lugs. This coating can in particular be made of PTFE, or of polyurethane loaded with a perfluoropolyether oil (PFPE).

Concernant le bouton poussoir 1, il a une surface d'appui circulaire surmontant une base tronconique avec un évidement en son centre pour le passage de l'axe 17. Les surfaces de contact entre le bouton poussoir 1 et les bras 5',5" sont agencées de façon à glisser aisément l'une sur l'autre. Il peut se révéler utile d'améliorer ce glissement par un choix adéquat de matériaux, en utilisant soit un matériau intrinsèquement glissant tel qu'un polymère fluoré, soit un revêtement d'un tel polymère. Toujours de manière à faciliter le glissement du bouton poussoir, ce dernier présente une forme conique avec une paroi inclinée d'un angle de préférence compris entre 30 et 60° plus préférentiellement entre 40 et 50° par rapport à l'axe 17. La pente du bouton poussoir est choisie de manière à ce que la course du bouton soit comprise entre 0.3 et 0.8 mm.Concerning the push button 1, it has a circular bearing surface surmounting a frustoconical base with a recess in its center for the passage of the axis 17. The contact surfaces between the push button 1 and the arms 5 ', 5 " are arranged so as to slide easily over one another It may be useful to improve this sliding by an adequate choice of materials, using either an inherently slippery material such as a fluoropolymer, or a coating of 'such a polymer. Still so as to facilitate the sliding of the push button, the latter has a conical shape with a wall inclined at an angle preferably between 30 and 60 °, more preferably between 40 and 50 ° with respect to the axis 17. The slope of the push button is chosen so that the stroke of the button is between 0.3 and 0.8 mm.

Avantageusement, le bouton poussoir peut être monté sur des moyens élastiques tels qu'un ressort ou une lame (non représentés) qui aident, en complément du ressort 2 positionné entre les tiges, au rappel du bouton poussoir en position haute lorsque ce dernier est relâché. Ces moyens élastiques peuvent être utilisés comme détrompeur sonore. A cet effet, les moyens élastiques peuvent comporter une lame métallique souple qui se tend lorsque l'organe de commande est pressé et se détend lorsqu'il remonte au-delà d'une certaine course, la détente de la lame déclenchant un clic distinctif qui a pour autre avantage de signaler à l'utilisateur que les tiges, et dès lors le bracelet, sont correctement fixés à la boîte de montre.Advantageously, the push button can be mounted on resilient means such as a spring or a leaf (not shown) which help, in addition to the spring 2 positioned between the rods, in the return of the push button to the high position when the latter is released. . These elastic means can be used as a sound fool. For this purpose, the elastic means may include a flexible metal blade which stretches when the actuator is pressed and relaxes when it rises beyond a certain stroke, the trigger of the blade triggering a distinctive click which has the further advantage of signaling to the user that the rods , and therefore the bracelet, are correctly attached to the watch case.

Le fonctionnement du dispositif est illustré aux travers des figures 1 et 4. Lorsque le bouton 1 est pressé (figure 4), les surfaces latérales inclinées du bouton 1 appuient sur les surfaces correspondantes des bras 5',5". Ce faisant, les bras 5',5" s'écartent entre l'axe 11 et le point de croisement 12. Cet écartement induit un déplacement des chevilles 9',9" à l'extrémité des bras 5',5" dans les lumières de guidage 18',18". Ce mouvement de rotation induit un mouvement de translation latéral et vertical des biellettes 6',6". La translation verticale des biellettes 6',6" est reprise par le coulissement de celles-ci entre les parois 13',13" et par le coulissement du doigt 15',15" dans la lumière correspondante 16',16". Par contre, le mouvement latéral des biellettes 6',6" induit un mouvement correspondant des tiges 4',4" et, de ce fait, la rétractation des tiges 4',4". Lorsque la pression sur le bouton 1 est relâchée, le ressort 2 repousse les tiges 4',4" en position de repos, repoussant les bras 5',5" qui à leur tour repoussent le bouton 1 en position de repos, éventuellement aidé par les moyens élastiques additionnels susmentionnés.The operation of the device is illustrated through figures 1 and 4 . When button 1 is pressed ( figure 4 ), the inclined lateral surfaces of the button 1 press on the corresponding surfaces of the arms 5 ', 5 ". In doing so, the arms 5', 5" move apart between the axis 11 and the crossing point 12. This separation induces a displacement of the pins 9 ', 9 "at the end of the arms 5', 5" in the guide slots 18 ', 18 ". This rotational movement induces a lateral and vertical translational movement of the rods 6', 6" . The vertical translation of the rods 6 ', 6 "is taken up by the sliding of the latter between the walls 13', 13" and by the sliding of the finger 15 ', 15 "in the corresponding slot 16', 16". On the other hand, the lateral movement of the rods 6 ', 6 "induces a corresponding movement of the rods 4', 4" and, therefore, the retraction of the rods 4 ', 4 ". When the pressure on the button 1 is released, the spring 2 pushes the rods 4 ', 4 "back into the rest position, pushing back the arms 5', 5" which in turn push the button 1 back into the rest position, possibly aided by the aforementioned additional elastic means.

Selon l'invention, la plaque support 14 surmontée du mécanisme est disposée de manière invisible au sein du bracelet. Le dispositif de fixation peut ainsi être disposé au sein d'un bracelet en cuir, en textile tissé ou brodé ou en plastique avec un repère signalant à l'utilisateur l'endroit où appuyer sur le bouton. Il est aussi envisageable de placer le dispositif de fixation selon l'invention sur un bracelet métallique ou en céramique dans une partie plastique surmoulée sur un maillon du bracelet. Dans tous les cas de figure, c'est la souplesse du matériau du bracelet qui permet d'actionner le bouton poussoir noyé au sein du bracelet. De préférence, la surface d'appui de l'organe de commande est positionnée entre 0.2 et 0.7 mm sous la surface du bracelet. Elle peut être disposée sous la face intérieure du bracelet, c.à.d. celle destinée à être placée en regard du poignet, ou inversement sous la face extérieure du bracelet.According to the invention, the support plate 14 surmounted by the mechanism is arranged invisibly within the bracelet. The fastening device can thus be placed within a leather, woven or embroidered textile or plastic strap with a mark indicating to the user where to press the button. It is also possible to envisage placing the fixing device according to the invention on a metal or ceramic bracelet in a plastic part overmolded on a link of the bracelet. In all cases, it is the flexibility of the material of the bracelet which makes it possible to actuate the push button embedded in the bracelet. Preferably, the bearing surface of the control member is positioned between 0.2 and 0.7 mm below the surface of the bracelet. It can be placed under the inner face of the bracelet, i.e. that intended to be placed opposite the wrist, or vice versa under the outer face of the bracelet.

Pour finir, on précisera que la plaque de support 14 munie du mécanisme peut être enfermée dans un carter percé d'une ouverture pour le passage du bouton poussoir. A cet effet, la plaque peut être délimitée à certains endroits par des rebords 17 d'une hauteur sensiblement égale à celle des bras superposés, sur ces rebords repose un couvercle de fermeture (non représenté).Finally, it should be specified that the support plate 14 provided with the mechanism can be enclosed in a housing pierced with an opening for the passage of the push button. For this purpose, the plate can be delimited in certain places by flanges 17 of a height substantially equal to that of the superimposed arms, on these flanges rests a closing cover (not shown).
