Description

La présente invention concerne un fermoir pour bracelet de montre. Plus précisément, la présente invention concerne un fermoir pour bracelet de montre comprenant des moyens qui permettent un réglage fin de la longueur du bracelet.The present invention relates to a clasp for a watch strap. More specifically, the present invention relates to a clasp for a watch strap comprising means that allow fine adjustment of the length of the bracelet.

Des fermoirs comprenant des moyens pour un réglage fin de la longueur du bracelet d'une montre sont déjà connus de l'état de la technique. Par fermoir pour réglage fin de la longueur d'un bracelet, on entend des fermoirs qui permettent de régler sur une faible course la longueur d'un bracelet afin de permettre d'adapter au plus juste cette longueur pour un confort optimal au porter de la montre. De tels fermoirs comprennent usuellement un maillon terminal par l'intermédiaire duquel l'un des brins du bracelet est relié au couvercle du fermoir. Ce maillon terminal est apte à coulisser selon une direction longitudinale du fermoir entre une première position rétractée dans laquelle il vient se loger dans le couvercle du fermoir et une seconde position sortie dans laquelle il est dégagé du fermoir. Par conséquent, la longueur disponible pour le réglage fin est déterminée par la course du maillon terminal entre ses première et seconde positions. Pour l'indexation de la position du maillon terminal, le maillon terminal coopère via un élément denté avec une denture de crémaillère. A titre d'exemple, la crémaillère peut être solidaire du couvercle du fermoir et l'élément denté être porté par le maillon terminal. La permutation de la denture de crémaillère et de l'élément denté est également envisageable.Clasps comprising means for a fine adjustment of the length of the wristband of a watch are already known from the state of the art. Clasp for fine adjustment of the length of a bracelet, means clasps that allow to adjust the length of a short strap to allow to fit the fairest length for optimal comfort when wearing the bracelet. shows. Such clasps usually include a terminal link through which one of the strands of the bracelet is connected to the lid of the clasp. This terminal link is slidable in a longitudinal direction of the clasp between a first retracted position in which it is housed in the lid of the clasp and a second extended position in which it is disengaged from the clasp. Therefore, the length available for the fine adjustment is determined by the travel of the end link between its first and second positions. For indexing the position of the end link, the end link cooperates via a toothed element with a toothed rack. For example, the rack can be secured to the lid of the clasp and the toothed element be carried by the terminal link. The permutation of the rack teeth and the toothed element is also possible.

Lorsque l'élément denté est en prise avec la denture de crémaillère, le maillon terminal est immobilisé. Pour désengager l'élément denté de sa prise avec la denture de crémaillère, on prévoit des moyens élastiques de désaccouplement. Ces moyens élastiques se présentent habituellement sous la forme d'une lame élastique qui offre une faible course de désaccouplement. Du fait de la faible course de la lame élastique, les dents de la denture de crémaillère ne peuvent pas être très hautes. Par conséquent, la force du crantage entre l'élément denté et la denture à crémaillère est relativement faible, de sorte que la position du maillon terminal peut être facilement désindexée, par exemple en tirant ou en poussant le maillon terminal, ce qui n'est pas acceptable. En outre, on comprend aisément que, plus les dents de la denture de crémaillère sont petites, plus les tolérances de fabrication sont élevées, ce qui renchérit le prix de revient d'un tel fermoir.When the toothed element is engaged with the rack teeth, the end link is immobilized. To disengage the toothed element from its engagement with the rack teeth, resilient means of uncoupling are provided. These elastic means are usually in the form of an elastic blade which offers a small uncoupling stroke. Due to the short stroke of the elastic blade, the teeth of the rack teeth can not be very high. Consequently, the force of the notching between the toothed element and the rack tooth is relatively small, so that the position of the end link can be easily deindexed, for example by pulling or pushing the end link, which is not not acceptable. In addition, it is easily understood that, the teeth of the rack teeth are small, the higher the manufacturing tolerances, which increases the cost of such a clasp.

La présente invention a pour but de remédier aux inconvénients mentionnés ci-dessus ainsi qu'à d'autres encore en procurant un fermoir pour le réglage fin de la longueur d'un bracelet de montre permettant notamment de conserver le réglage de la longueur du bracelet sans risque de le perdre par inadvertance.The present invention aims to overcome the drawbacks mentioned above as well as others by providing a clasp for the fine adjustment of the length of a watch strap including maintaining the adjustment of the length of the bracelet without risk of losing it inadvertently.

A cet effet, la présente invention concerne un fermoir pour bracelet de montre comprenant un couvercle relié d'un premier côté à un premier brin de bracelet et d'un second côté à un second brin de bracelet, des moyens de liaison étant interposés entre le second brin de bracelet et le couvercle du fermoir, ces moyens de liaison comprenant un maillon terminal coulissant suivant une direction longitudinale du fermoir entre une première position dans laquelle le maillon terminal est au moins partiellement engagé dans le couvercle du fermoir, et une seconde position dans laquelle le maillon terminal est dégagé du couvercle du fermoir, l'élément terminal comprenant un bouton-poussoir par pression sur lequel il est possible de faire passer un élément denté d'une première position dans laquelle l'élément denté est en prise avec une denture de crémaillère solidaire du couvercle du fermoir, à une seconde position dans laquelle l'élément denté est libéré de son engagement avec la denture de crémaillère, le fermoir étant caractérisé en ce que le maillon terminal comprend un logement dans lequel est disposé au moins un ressort, ce ressort étant coiffé par le bouton-poussoir.For this purpose, the present invention relates to a clasp for a watch strap comprising a cover connected from one side to a first strand of a bracelet and from a second side to a second strand of bracelet, connecting means being interposed between the second strand of bracelet and the clasp cover, these connecting means comprising a sliding terminal link in a longitudinal direction of the clasp between a first position in which the terminal link is at least partially engaged in the clasp cover, and a second position in wherein the end link is disengaged from the clasp cover, the end member comprising a push-button on which it is possible to pass a toothed element from a first position in which the toothed element is engaged with a toothing. rack integral with the clasp cover, at a second position in which the toothed element is released from its enga with the rack teeth, the clasp being characterized in that the terminal link comprises a housing in which is arranged at least one spring, this spring being capped by the pushbutton.

Grâce à ces caractéristiques, la présente invention procure un fermoir pour bracelet de montre dans lequel le désengagement entre l'élément denté et la denture de crémaillère est commandé par au moins un ressort. Un tel ressort procure au bouton-poussoir une course substantielle, cette course étant seulement déterminée par la longueur du ressort. Comme le bouton-poussoir commande directement le passage de l'élément denté de sa première position dans laquelle il est en prise avec la denture de crémaillère à sa seconde position dans laquelle il est libéré de son engagement avec la denture de crémaillère, la course de l'élément denté entre ses deux positions extrêmes est également plus importante. Par voie de conséquence, les dents de la denture de crémaillère peuvent être réalisées plus hautes que tel n'était le cas dans l'état de la technique et donc les espaces entres les dents plus profonds. La force du crantage entre l'élément denté et la denture à crémaillère est donc plus élevée, de sorte que la position du maillon terminal ne peut être désindexée, sauf à détruire le fermoir. En outre, comme les dents de la denture de crémaillère sont plus hautes, les tolérances de fabrication sont moins strictes, ce qui permet de réaliser des gains en termes de prix de revient.Thanks to these features, the present invention provides a watch strap clasp in which the disengagement between the toothed element and the rack teeth is controlled by at least one spring. Such a spring provides the push button a substantial stroke, this stroke being determined only by the length of the spring. As the push button directly controls the passage of the toothed element from its first position in which it is engaged with the rack teeth to its second position in which it is released from its engagement with the rack teeth, the race of the toothed element between its two extreme positions is also larger. As a result, the teeth of the rack teeth can be made higher than was the case in the state of the art and therefore the spaces between the deeper teeth. The force of the notching between the toothed element and the rack tooth is therefore higher, so that the position of the end link can not be deindexed, except to destroy the clasp. In addition, as the teeth of the rack teeth are higher, the manufacturing tolerances are less stringent, which allows for gains in terms of cost.

Selon une caractéristique complémentaire de l'invention, le bouton-poussoir est équipé d'un moyen d'arrêt empêchant l'extraction du maillon terminal du couvercle de fermoir.According to a complementary feature of the invention, the push button is equipped with a stop means preventing extraction of the end link from the clasp cover.

Grâce à cette autre caractéristique, les moyens de liaison entre le couvercle du fermoir et le second brin de bracelet sont imperdables, sauf à détruire le fermoir. Additionnellement, selon une variante préférée de l'invention, le moyen d'arrêt est démontable, ce qui permet, si nécessaire, de remplacer le maillon terminal ou le bouton-poussoir lors d'un retour de la montre-bracelet en service après-vente.Thanks to this other characteristic, the connecting means between the clasp cover and the second bracelet strand are captive, except to destroy the clasp. Additionally, according to a preferred variant of the invention, the stop means can be dismantled, which makes it possible, if necessary, to replace the end link or the push-button when the wristwatch returns to service afterwards. sale.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un mode de réalisation du fermoir pour bracelet de montre selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement en liaison avec le dessin annexé sur lequel:

  • la figure 1 est une vue en perspective et à l'état dissocié du fermoir selon l'invention;
  • la figure 2 est une vue en perspective du fermoir de la figure 1 à l'état assemblé, le maillon terminal de réglage fin étant en position rentrée;
  • la figure 3 est une vue analogue à celle de la figure 2, le maillon de réglage fin étant en position sortie, et
  • la figure 4 est une vue en coupe transversale du maillon terminal de réglage fin selon l'invention.
Other features and advantages of the present invention will emerge more clearly from the following detailed description of a method of realization of the clasp for a watch band according to the invention, this example being given purely by way of illustration and not limiting only in connection with the appended drawing in which:
  • the figure 1 is a perspective view and in the dissociated state of the clasp according to the invention;
  • the figure 2 is a perspective view of the clasp of the figure 1 in the assembled state, the fine adjustment end link being in the retracted position;
  • the figure 3 is a view similar to that of the figure 2 the fine adjustment link being in the extended position, and
  • the figure 4 is a cross-sectional view of the fine adjustment end link according to the invention.

La présente invention procède de l'idée générale inventive qui consiste à utiliser un ressort comme moyen élastique contrôlant le désaccouplement entre un élément denté et une denture de crémaillère d'un maillon de réglage fin d'un fermoir pour bracelet de montre. Un tel ressort procure une course plus importante au bouton-poussoir qui lui est associé, de sorte que le déplacement de l'élément denté commandé par le bouton-poussoir de sa première position dans laquelle il est en prise avec la denture de crémaillère à sa seconde position dans laquelle il est libéré de son engagement avec la denture de crémaillère est également plus important. Les dents de la denture de crémaillère peuvent donc être prévues plus hautes avec des creux entre les dents plus profonds, ce qui assure un meilleur crantage de l'élément denté et permet de réduire les tolérances de fabrication des dents de la denture de crémaillère.The present invention proceeds from the general inventive idea of using a spring as an elastic means controlling the uncoupling between a toothed element and a toothed rack of a fine tuning link of a clasp for a watch band. Such a spring provides a greater stroke to the pushbutton associated therewith, so that the displacement of the toothed element controlled by the push button from its first position in which it is engaged with the rack teeth at its second position in which it is released from engagement with the rack teeth is also more important. The teeth of the rack teeth can therefore be provided higher with deeper teeth recesses, which ensures a better notch of the toothed element and reduces the manufacturing tolerances of the teeth of the rack teeth.

La figure 1 est une vue en perspective à l'état dissocié du fermoir selon l'invention tandis que la figure 2 est une vue en perspective de ce même fermoir à l'état assemblé. Désigné dans son ensemble par la référence numérique générale 1, le fermoir selon l'invention comprend un couvercle 2 relié d'un premier côté à un premier brin de bracelet 4 dont un seul maillon est visible au dessin avec interposition d'un système de fermeture à boucle déployante 6 dont la structure est connue en soi et qui ne sera donc pas décrit davantage ici. On notera que le système de fermeture à boucle déployante 6 peut être omis et que le couvercle 2 peut être relié au premier brin de bracelet 4 directement. Le couvercle 2 est relié d'un second côté à un second brin de bracelet 8 dont trois maillons sont visibles au dessin avec interposition d'un maillon terminal 10 de réglage fin de la longueur du bracelet de la montre.The figure 1 is a perspective view in the dissociated state of the clasp according to the invention while the figure 2 is a perspective view of this same clasp in the assembled state. Designated as a whole by the general numerical reference 1, the clasp according to the invention comprises a lid 2 connected on one side to a first strand of bracelet 4, of which only one link is visible in the drawing with the interposition of a clasp closure 6 whose structure is known per se and therefore will not be described further here. Note that the clasp closure system 6 can be omitted and the cover 2 can be connected to the first strand of bracelet 4 directly. The lid 2 is connected on the second side to a second strand of bracelet 8, three links of which are visible in the drawing with the interposition of a terminal link 10 for fine adjustment of the length of the wristband of the watch.

Comme on peut le voir à l'examen de la figure 1, le couvercle 2 présente une section générale en forme de U et est muni de deux ailes 12 se faisant face, ces ailes 12 portant chacune sur leur face dirigée vers l'intérieur une denture de crémaillère 14. Par ailleurs, une rainure 16 est ménagée dans le fond du couvercle 2 et définit deux butées d'extrémité 18 dont le rôle sera décrit en détail ultérieurement. Enfin, le maillon terminal 10 comprend des surfaces de guidage latérales 19 afin d'être guidé à coulissement dans le couvercle 2 entre le fond du couvercle 2 et les ailes 12. On appréciera par examen comparé des figures 2 et 3 que le maillon terminal 10 est capable de coulisser suivant une direction longitudinale du fermoir 1 entre une première position (figure 2) dans laquelle le maillon terminal 10 est engagé dans le couvercle 2 du fermoir 1, et une seconde position (figure 3) dans laquelle le maillon terminal 10 est dégagé du couvercle 2 du fermoir 1. La longueur disponible pour le réglage du bracelet est déterminée par la course du maillon terminal 10 entre ses première et seconde positions.As can be seen from the examination of the figure 1 , the lid 2 has a U-shaped general section and is provided with two flanges 12 facing each other, these flanges 12 each carrying on their inwardly directed face a rack toothing 14. Furthermore, a groove 16 is provided in the bottom of the cover 2 and defines two end stops 18 whose role will be described in detail later. Finally, the terminal link 10 comprises lateral guide surfaces 19 to be slidably guided in the cover 2 between the bottom of the cover 2 and the wings 12. It will be appreciated by comparative examination of figures 2 and 3 the end link 10 is capable of sliding in a longitudinal direction of the clasp 1 between a first position ( figure 2 ) in which the end link 10 is engaged in the cover 2 of the clasp 1, and a second position ( figure 3 ) in which the end link 10 is disengaged from the cover 2 of the clasp 1. The length available for the adjustment of the bracelet is determined by the travel of the end link 10 between its first and second positions.

Le maillon terminal 10 comprend deux charnons extrêmes 20 entre lesquels vient s'imbriquer le charnon médian 22 du maillon voisin du second brin de bracelet 8. L'assemblage entre les maillons est assuré par une barrette 24 traversant librement les charnons 20 et 22 et qui est maintenue par deux vis d'extrémité 26.The end link 10 comprises two end knuckles 20 between which the middle knuckle 22 of the adjoining link of the second strand of bracelet 8 is interlocked. The assembly between the links is ensured by a bar 24 freely traversing the knuckles 20 and 22 and which is held by two end screws 26.

Le maillon terminal 10 comprend au moins un et, préférentiellement, deux logements borgnes cylindriques 28 dans chacun desquels est disposé un ressort hélicoïdal 30, ces ressorts 30 étant coiffés par un bouton-poussoir 32. Ce bouton-poussoir 32 se présente sensiblement sous la forme d'une barre d'actionnement rectiligne qui s'étend transversalement à l'axe de symétrie longitudinale du fermoir 1 et qui présente à chacune de ses extrémités un élément denté 34 par exemple sous la forme d'un demi-cylindre. Ces éléments dentés 34 sont destinés à venir en prise avec la denture des crémaillères 14. On comprendra que lorsque le maillon terminal 10 et son bouton-poussoir 32 sont glissés entre les deux ailes 12 à l'intérieur du couvercle 2 du fermoir 1 comme illustré à la figure 2, les ressorts hélicoïdaux 30 qui sont montés comprimés forcent le bouton-poussoir 32 en direction des crémaillères 14, de sorte que les éléments dentés 34 sont en prise avec les dentures des crémaillères 14. Inversement, lorsqu'on appuie sur le bouton-poussoir 32 suivant la flèche A à l'encontre de la force de rappel élastique des ressorts 30, les éléments dentés 34 sont libérés de leur engagement avec les dentures de crémaillères 14. On comprendra également que les ressorts hélicoïdaux 30 confèrent au bouton-poussoir 32 et donc aux éléments dentés 34 une course importante, de sorte que les dents des dentures de crémaillères 14 peuvent être hautes et les espaces entre ces dents profonds. Par suite, les éléments dentés 34 sont parfaitement crantés dans les dentures des crémaillères 14, de sorte qu'il est impossible de perdre accidentellement le réglage du maillon terminal 10. En outre, les exigences sur les tolérances des dentures de crémaillères 14 sont moindres, ce qui permet de réaliser des gains en termes de coûts de production.The terminal link 10 comprises at least one and, preferably, two cylindrical blind housings 28 in each of which is disposed a helical spring 30, these springs 30 being capped by a push-button 32. This push button 32 is substantially in the form of a rectilinear actuating bar which extends transversely to the longitudinal axis of symmetry of the clasp 1 and which has at each of its ends a toothed element 34 for example in the form of a half-cylinder. These toothed elements 34 are intended to come into engagement with the toothing of the racks 14. It will be understood that when the end link 10 and its pushbutton 32 are slid between the two wings 12 inside the cover 2 of the clasp 1 as illustrated. to the figure 2 , the coil springs 30 which are mounted force the push button 32 towards the racks 14, so that the toothed elements 34 are engaged with the teeth of the racks 14. Conversely, when the push button 32 is depressed following the arrow A against the elastic return force of the springs 30, the toothed elements 34 are released from their engagement with the toothed racks 14. It will also be understood that the coil springs 30 give the push button 32 and therefore To the toothed elements 34 a large stroke, so that the teeth of the rack teeth 14 can be high and the spaces between these deep teeth. As a result, the toothed elements 34 are perfectly notched in the teeth of the racks 14, so that it is impossible to accidentally lose the setting of the end link 10. In addition, the requirements on the tolerances of the toothed racks 14 are smaller, which allows to realize gains in terms of production costs.

On observe également à l'examen des figures 1 et 4 qu'entre les deux logements cylindriques borgnes 28 ménagés dans le maillon terminal 10 est prévu un premier trou traversant fileté 36 dans lequel est vissée une vis 38 dont la pointe fait saillie dans la rainure 16 ménagée dans le fond du couvercle 2. Comme cette rainure 16 est bornée à chacune de ses extrémités par une butée 18 qui marque le fond de la rainure 16, le maillon terminal 10 de réglage fin est totalement imperdable une fois la vis 38 vissée. Enfin, un second trou traversant 40 aligné avec le premier trou traversant fileté 36 est usiné dans le bouton-poussoir 32. Selon une première variante de réalisation de l'invention, un bouchon (non représenté) est chassé ou collé dans le second trou traversant 40 afin de masquer la vis 38 et ne pas laisser apparaître un trou au regard de l'utilisateur. Dans ce cas cependant, le bouton-poussoir 32 est définitivement indémontable. Selon une seconde variante de réalisation de l'invention, une vis 42 est vissée dans le second trou traversant 40. Cette vis 42 masque la vis 38 au regard de l'utilisateur. Cependant, l'ensemble reste démontable dans la mesure où il suffit de déposer la vis 42 pour pouvoir ensuite retirer la vis 38. Ces deux variantes de réalisation sont préférées à la variante dans laquelle ne serait prévue qu'une seule vis suffisamment longue pour que la tête de cette vis affleure la surface du bouton-poussoir 32. En effet, dans ce mode de réalisation, la tête de la vis ferait saillie du bouton-poussoir 32 lorsque celui-ci est pressé à l'encontre de la force de rappel élastique des ressorts 30, ce qui n'est pas esthétique.We also observe the examination of figures 1 and 4 that between the two blind cylindrical housings 28 formed in the end link 10 is provided a first threaded through hole 36 in which is screwed a screw 38 whose tip projects into the groove 16 formed in the bottom of the lid 2. As this groove 16 is bounded at each of its ends by a stop 18 which marks the bottom of the groove 16, the end link 10 of fine adjustment is completely captive once the screw 38 screwed. Finally, a second through-hole 40 aligned with the first threaded through hole 36 is machined in the push-button 32. According to a first alternative embodiment of the invention, a plug (not shown) is driven or glued into the second through hole 40 to hide the screw 38 and not to reveal a hole in front of the user. In this case, however, the pushbutton 32 is permanently unmountable. According to a second variant embodiment of the invention, a screw 42 is screwed into the second through hole 40. This screw 42 masks the screw 38 with respect to the user. However, the assembly remains removable to the extent that it is sufficient to remove the screw 42 to then be able to remove the screw 38. These two variants are preferred to the variant in which only one screw is provided that is long enough for the head of this screw is flush with the surface of the pushbutton 32. Indeed, in this embodiment, the head of the screw protrudes from the pushbutton 32 when it is pressed against the return force spring elastic 30, which is not aesthetic.

On notera qu'en fond des logements borgnes cylindriques 28 sont prévus deux tenons 44 pour le centrage des ressorts 30. Par ailleurs, le bouton-poussoir 32 est muni sur sa surface en regard du maillon terminal 10 de réglage fin de deux logements cylindriques 46 coaxiaux avec les logements borgnes cylindriques 28 pour le guidage et le maintien des ressorts 30.It will be noted that at the bottom of the cylindrical blind housings 28 are provided two pins 44 for centering the springs 30. Furthermore, the push-button 32 is provided on its surface facing the end link 10 of fine adjustment of two cylindrical housings 46 coaxial with cylindrical blind housings 28 for guiding and holding springs 30.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples pourront être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants may be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims.
