Description

La présente invention concerne un dispositif de fixation d'un bracelet de montre sur une boíte de montre comportant un gond solidaire de la boíte de montre dans lequel coulissent deux pivots soumis à l'action d'un premier ressort de rappel tendant à les écarter de manière à ce que les extrémités externes des pivots émergent hors des faces latérales dudit gond et comportant un élément de fixation fixé à ou intégré dans l'extrémité d'un bracelet muni de deux pattes définissant entre elles un espace destiné à recevoir le gond, chacune de ces pattes comportant un évidement axial débouchant dans l'espace compris entre ces pattes.The present invention relates to a device for fixing a bracelet watch on a watch case having a hinge secured to the case shows in which two pivots slide subject to the action of a first spring reminder tending to separate them so that the outer ends of the pivots emerge from the lateral faces of said hinge and comprising an element of fastening attached to or integrated into the end of a bracelet fitted with two tabs defining between them a space intended to receive the hinge, each of these legs having an axial recess opening into the space between these legs.

Cette invention doit être vue dans le contexte de bracelets interchangeables permettant de changer le bracelet d'une montre pour certaines occasions ou selon la volonté du propriétaire de la montre. De tels bracelets interchangeables existent, néanmoins comportant un certain nombres de désavantages. Soit les bracelets de ce genre se démontent et montent facilement et sans outils par l'utilisateur, mais ont dans ce cas l'inconvénient de risquer de se défaire tout seul et ainsi de faire tomber ou même perdre la montre. Soit ce risque est affaibli ou écarté, les bracelets ayant dans ce cas souvent le désavantage de nécessiter un outil afin d'être changés, ceci étant contraire au but envisagé.This invention must be seen in the context of interchangeable bracelets allowing to change the strap of a watch for certain occasions or according to the will of the watch owner. Such interchangeable bracelets exist, however with a number of disadvantages. Either bracelets of this kind can be disassembled and mounted easily and without tools by the user, but in this case have the disadvantage of risking unraveling alone and thus to drop or even lose the watch. Either this risk is reduced or discarded, the bracelets often having the disadvantage of requiring a tool in order to be changed, this being contrary to the envisaged goal.

Le but de la présente invention est d'apporter une solution facile à ce problème contradictoire en réalisant un dispositif de fixation d'un bracelet sur une boíte de montre qui permette une interchangeabilité du bracelet pouvant être effectuée facilement et rapidement par l'utilisateur. En particulier, cette opération ne nécessite pas le recours à un outil. Simultanément, cette solution garanti une amélioration au niveau de la sécurité de cette opération due au fait que le risque que la liaison entre le bracelet interchangeable et la montre ne se défasse est grandement diminué. Ainsi, cette invention permet aux utilisateurs de fixer eux-mêmes sur une montre des bracelets selon leurs goûts, par exemple en différentes couleurs ou différentes matières comme en métal, cuir etc.The purpose of the present invention is to provide an easy solution to this contradictory problem by making a device for attaching a bracelet to a watch case which allows interchangeability of the bracelet which can be performed easily and quickly by the user. In particular, this operation does not require the use of a tool. At the same time, this solution guarantees a improvement in the safety of this operation due to the fact that the risk that the link between the interchangeable strap and the watch does not come undone is greatly decreased. So, this invention allows users to fix themselves on a watch bracelets according to their tastes, for example in different colors or different materials such as metal, leather etc.

La présente invention a pour objet un dispositif de fixation d'un bracelet de montre sur une boíte de montre qui se distingue par le fait que l'évidement axial est prolongé en direction des faces latérales externes des pattes par un orifice hébergeant un contre-pivot monté de façon coulissante dans cet évidement et portant un poussoir fixé aux extrémités externes des contre-pivots, et par le fait que le gond comporte sur ses faces latérales un logement annulaire ayant une rainure définissant une orientation privilégiée, ce logement annulaire étant destiné à coopérer avec une protubérance placée sur les faces intérieures des pattes.The present invention relates to a device for fixing a bracelet watch on a watch case which is distinguished by the fact that the axial recess is extended towards the external lateral faces of the legs by an orifice accommodating a sliding pivot mounted in this recess and carrying a pusher attached to the outer ends of the counter-pivots, and thereby that the hinge has on its lateral faces an annular housing having a groove defining a preferred orientation, this annular housing being intended to cooperate with a protuberance placed on the inner faces of the legs.

Les dessins annexés illustrent schématiquement et à titre d'exemple une forme d'exécution du dispositif de fixation d'un bracelet sur une boíte de montre selon l'invention.The accompanying drawings illustrate schematically and by way of example a embodiment of the device for attaching a bracelet to a watch case according to the invention.

La figure 1 illustre une boíte de montre équipée du dispositif de fixation selon l'invention, accouplée à des pièces de liaisons que comportent les extrémités du bracelet.Figure 1 illustrates a watch case equipped with the fixing device according to the invention, coupled to connecting parts that comprise the ends of the bracelet.

La figure 2 est une coupe partielle passant par la ligne A-A de la figure 1 suivant un plan perpendiculaire au fond de la boíte de montre.Figure 2 is a partial section through line A-A in Figure 1 along a plane perpendicular to the bottom of the watch case.

La figure 3 est une illustration de l'opération de mise en place du bracelet sur la boíte de montre.Figure 3 is an illustration of the operation of fitting the bracelet on the watch case.

Le dispositif de fixation d'un bracelet sur une boíte de montre illustré à la figure 1 comporte un gond 1 solidaire de la boíte de montre 2, remplaçant en quelque sorte les cornes habituelles, et un élément de fixation 3 destiné à être fixé sur l'extrémité d'un bracelet devant être accouplé à la boíte de montre 2. Cet élément 3 peut également être intégré de fabrication à l'extrémité du bracelet, comme le montre la figure 3.The device for attaching a bracelet to a watch case illustrated in Figure 1 has a hinge 1 secured to the watch case 2, replacing sort of the usual horns, and a fastening element 3 intended to be fixed on the end of a bracelet to be coupled to the watch case 2. This element 3 can also be integrated at the end of the bracelet, as shown in figure 3.

Chaque gond 1 comporte un passage transversal traversant présentant trois parties, une partie de faible diamètre 4 débouchant sur l'une de ses tranches latérales, une partie médiane 5 de plus grand diamètre et une partie de grand diamètre 6, munie d'un filetage 7, débouchant sur l'autre tranche latérale du gond 1.Each hinge 1 has a transverse passage having three parts, a small diameter part 4 leading to one of its edges lateral, a middle part 5 of larger diameter and a part of large diameter 6, provided with a thread 7, leading to the other lateral edge of the hinge 1.

Dans ce passage transversal 4, 5, 6 sont logés deux pivots 8, 9 comportant une partie centrale d'un diamètre correspondant au diamètre de la partie médiane 5 du passage traversant du gond 1. Chaque pivot comporte une extrémité interne de plus faible diamètre introduite dans un premier ressort à boudin 10 également logé dans le passage transversal 4, 5, 6 et tendant à écarter les pivots 8, 9 l'un de l'autre.In this transverse passage 4, 5, 6 are housed two pivots 8, 9 comprising a central part with a diameter corresponding to the diameter of the middle part 5 of the through passage of the hinge 1. Each pivot has an internal end of smaller diameter introduced into a first coil spring 10 also housed in the transverse passage 4, 5, 6 and tending to separate the pivots 8, 9 one of the other.

Une douille filetée 11 est vissée dans le filetage 7 et comporte un perçage terminal 12 de même diamètre que la partie 4 de faible diamètre du passage transversal 4, 5, 6 du gond 1 débouchant dans un logement 13 présentant un diamètre correspondant à celui de la partie médiane du passage transversal 4, 5, 6. Dans ce logement 13 coulisse la partie médiane du pivot 9.A threaded sleeve 11 is screwed into the thread 7 and has a hole terminal 12 of the same diameter as the small diameter part 4 of the passage transverse 4, 5, 6 of the hinge 1 opening into a housing 13 having a diameter corresponding to that of the middle part of the transverse passage 4, 5, 6. In this housing 13 slides the middle part of the pivot 9.

Ainsi, en position de service les pivots 8, 9 coulissent transversalement dans le gond 1 et sont soumis à l'action du ressort 10 qui tend à les écarter l'un de l'autre. Les parties terminales externes du pivot 8, 9 émergent des faces latérales du gond 1 et les pivots 8, 9 sont retenus par leur épaulement 14 venant en butée contre le gond 1 respectivement la douille 11 vissée dans le gond 1 comme illustré à la figure 2.Thus, in the service position the pivots 8, 9 slide transversely in the hinge 1 and are subjected to the action of the spring 10 which tends to separate them one of the other. The external end parts of the pivot 8, 9 emerge from the side faces hinge 1 and pivots 8, 9 are retained by their shoulder 14 abutting against the hinge 1 respectively the socket 11 screwed into the hinge 1 as illustrated in Figure 2.

Le gond 1 comporte encore, sur ses faces latérales, un logement annulaire 25 entourant, en laissant vide un espace annulaire, les parties terminales externes du pivot 8, 9 émergeant dans ces faces latérales. De plus, ce logement annulaire 25 comporte une rainure 26, comme illustré à la figure 3, qui défini une orientation privilégiée du bracelet interchangeable destinée à être mise en place sur le gond 1. Cette rainure 26 est de préférence orientée perpendiculairement vers le bas par rapport à la boíte de montre. L'angle entre une ligne longeant un côté de cette rainure 26 et le plan du fond de la boíte de montre est ainsi compris, de préférence entre 80° et 100°, et est, dans l'exemple illustré, un angle droit. Le logement annulaire 25 est plus profond à la face du gond 1 destiné à recevoir la douille 11, de manière à ce que la profondeur effective des logements annulaires 25 est identique à chaque face latérale du gond 1 une fois que cette douille 11 est vissée dans le gond 1.The hinge 1 also comprises, on its lateral faces, an annular housing 25 surrounding, leaving an annular space empty, the outer terminal parts pivot 8, 9 emerging in these side faces. In addition, this annular housing 25 has a groove 26, as illustrated in FIG. 3, which defines an orientation privileged interchangeable strap intended to be fitted on the hinge 1. This groove 26 is preferably oriented perpendicularly downwards by compared to the watch case. The angle between a line along one side of this groove 26 and the plane of the bottom of the watch case is thus understood, from preferably between 80 ° and 100 °, and is, in the example illustrated, a right angle. The annular housing 25 is deeper on the face of the hinge 1 intended to receive the socket 11, so that the effective depth of the annular housings 25 is identical to each side face of the hinge 1 once this socket 11 is screwed into the hinge 1.

L'élément de fixation 3 peut être constitué par le dernier maillon d'un bracelet métallique ou par une pièce intégrée dans l'extrémité d'un bracelet cuir. Dans l'exemple illustré à la figure 3, l'élément 3 fait partie de l'extrémité du bracelet. Dans l'exemple illustré à la figure 1, cet élément 3 comporte un tenon muni d'un perçage. Ce tenon est destiné à être fixé à l'extrémité d'un bracelet métallique à l'aide d'une goupille passant dans ce perçage. Cet élément 3 comporte encore deux pattes 15 séparées par un évidement 16 destiné à recevoir le gond 1 de la boíte de montre. Ces pattes 15 comportent chacune un évidement 17 débouchant avec une partie 17b de plus grand diamètre comportant un filetage 17c sur leurs faces latérales externes. Une partie 17a de plus faible diamètre de cet évidement 17 débouche sur la tranche interne de ces pattes 15.The fastening element 3 may consist of the last link of a metallic bracelet or by a piece integrated into the end of a leather bracelet. In the example illustrated in Figure 3, element 3 is part of the end of the bracelet. In the example illustrated in FIG. 1, this element 3 comprises a tenon provided with a hole. This post is intended to be attached to the end of a bracelet metal using a pin passing through this hole. This item 3 still has two legs 15 separated by a recess 16 intended to receive hinge 1 of the watch case. These legs 15 each have a recess 17 opening out with a portion 17b of larger diameter comprising a thread 17c on their external lateral faces. A portion 17a of smaller diameter of this recess 17 opens onto the internal edge of these lugs 15.

Des embouts 19 sont vissés dans les parties 17b des évidements 17 des pattes 15 en utilisant le filetage 17c. Ces embouts 19 comportent un orifice traversant 22 prolongeant les évidements 17 vers l'extérieur et dans lequel coulisse un contre-pivot 21.End pieces 19 are screwed into the parts 17b of the recesses 17 of the legs 15 using thread 17c. These end pieces 19 have an orifice crossing 22 extending the recesses 17 outwards and in which slides a counter-pivot 21.

Ces embouts 19 peuvent être constitués d'une partie intérieure 19a principalement de forme cylindrique et d'une partie extérieure 19b qui, dans ce cas, peut être appliqué contre la face externe des pattes 15 par un épaulement extérieur des faces externes des parties intérieures 19a, comme représenté à la figure 2. Les embouts 19 pourraient tout de même être fabriqués d'une seule pièce.These end pieces 19 may consist of an inner part 19a mainly of cylindrical shape and an external part 19b which, in this case, can be applied against the external face of the legs 15 by a shoulder exterior of the exterior faces of the interior parts 19a, as shown in the Figure 2. The end pieces 19 could still be manufactured in one room.

La partie intérieure 19a des embouts 19 comporte encore, vers sa face intérieure, un épaulement 19c séparant le logement formé par l'évidement 17 des pattes 15 et l'orifice traversant 22 en deux parties et définissant simultanément un plus petit diamètre que celui de l'orifice traversant 22, qui est, de préférence, identique à celui de l'évidement 17. The inner part 19a of the end pieces 19 also has, towards its face interior, a shoulder 19c separating the housing formed by the recess 17 from the lugs 15 and the through hole 22 in two parts and simultaneously defining a smaller diameter than that of the through hole 22, which is preferably identical to that of the recess 17.

Ainsi, les contre-pivots 21 comportent deux parties de diamètres différents. Une partie intérieure du contre-pivot 21b présente un diamètre plus grand correspondant à celui de l'évidement 17, dans lequel cette partie 21b coulisse de façon à ce qu'elle soit retenue par l'épaulement 19c, contre lequel elle vient en butée. Une partie extérieure du contre-pivot 21a présente un diamètre plus petit correspondant à celui défini par l'épaulement 19c des embouts 19. Un deuxième ressort de rappel 18 peut par conséquent être logé entre la partie extérieure du contre-pivot 21a et la paroi intérieure de l'orifice traversant 22 des embouts 19. De telle sorte, le deuxième ressort de rappel 18 étant appliqué de sa face intérieure contre la face extérieure de l'épaulement 19c, qu'il tend à pousser vers l'extérieur un poussoir 20 fixé à l'extrémité externe de la partie extérieure du contre-pivot 21 a et logé dans la partie extérieure 19a des embouts 19. Ce poussoir 20 peut par exemple être vissé au filetage 24 de l'extrémité externe 23 du contre-pivot 21.Thus, the counter-pivots 21 comprise two parts of different diameters. An inner part of the pivot 21b has a larger diameter corresponding to that of the recess 17, in which this part 21b slides from so that it is retained by the shoulder 19c, against which it comes in stop. An outer part of the pivot 21a has a smaller diameter corresponding to that defined by the shoulder 19c of the end pieces 19. A second return spring 18 can therefore be housed between the outer part of the against pivot 21a and the inner wall of the through hole 22 of the end pieces 19. From such that the second return spring 18 is applied from its inner face against the outside face of the shoulder 19c, which it tends to push towards the outside a pusher 20 fixed to the outer end of the outer part of the pivot 21a and housed in the outer part 19a of the end pieces 19. This pusher 20 can by example be screwed to the thread 24 of the outer end 23 of the pivot 21.

La position normale des poussoirs 20, maintenue par les deuxièmes ressorts 18, est donc celle, dans laquelle la partie intérieure 21b des contre-pivots 21 est en butée contre l'épaulement 19c des embouts 19, les poussoirs étant poussés vers l'extérieur par ces ressorts 18.The normal position of the pushers 20, maintained by the second springs 18, is therefore that in which the inner part 21b of the pivot pins 21 abuts against the shoulder 19c of the end pieces 19, the pushers being pushed outward by these springs 18.

Dans la face intérieure de chaque patte 15 est agencée une protubérance 27 de forme annulaire dont la profondeur correspond au diamètre de l'extrémité des pivots 8, 9 émergeant latéralement du gond 1 ainsi qu'à la profondeur effective susmentionné des logements annulaires 25.In the inner face of each leg 15 is arranged a protuberance 27 of annular shape whose depth corresponds to the diameter of the end pivots 8, 9 emerging laterally from the hinge 1 and at depth effective above mentioned annular housings 25.

La largeur de cette protubérance 27 correspond à la largeur de la rainure 26 agencée dans le logement annulaire 25 afin que le bracelet puisse être introduit, en respectant l'orientation privilégiée susmentionnée, dans sa position dans laquelle la liaison avec la boíte de montre est installée. Dans cette position, les extrémités des pivots 8,9 émergeant latéralement du gond 1 sont, afin de stabiliser cette liaison, hébergées dans un évidement central 29 des protubérances 27 représentant un prolongement coaxial de même diamètre de l'évidement 17 des pattes 15. Pour faciliter l'opération de mise en place du bracelet et spécifiquement des extrémités externes des pivots 8, 9 dans ces évidements centraux 29, les protubérances 27 comportent encore une saignée de guidage 28 agencée sur les protubérances de manière à ce que, en rapprochant le bracelet dans l'orientation privilégiée vers le gond 1, les extrémités externes entre des pivots 8, 9 s'enclenchent dans les évidements 29 des protubérances 27 du gond 1. Ces saignées de guidage 28 sont notamment formées dans les protubérances 27 de préférence, à leur côté externe vue dans l'axe du bracelet, comme indiqué à la figure 3. Comme l'indique également cette figure, les parois extérieures des protubérances 27 peuvent comporter une partie droite alignée, le bracelet étant orienté dans la direction privilégiée en bas de la boíte de montre, avec les parois de la rainure 26 afin de renforcer la nécessité d'orienter les pièces correctement pour pouvoir monter ou démonter le bracelet.The width of this protuberance 27 corresponds to the width of the groove 26 arranged in the annular housing 25 so that the bracelet can be introduced, respecting the aforementioned preferred orientation, into its position in which the connection with the watch case is installed. In this position, the ends of the pivots 8,9 emerging laterally from the hinge 1 are, in order to stabilize this link, housed in a central recess 29 of protrusions 27 representing a coaxial extension of the same diameter of the recess 17 of the legs 15. To facilitate the operation of positioning the bracelet and specifically the outer ends of the pivots 8, 9 in these central recesses 29, the protrusions 27 also include a groove of guide 28 arranged on the protrusions so that, by bringing together the bracelet in the preferred orientation towards the hinge 1, the outer ends between pivots 8, 9 engage in the recesses 29 of the protrusions 27 hinge 1. These guide grooves 28 are in particular formed in the protrusions 27 preferably, at their external side seen in the axis of the bracelet, as shown in figure 3. As this figure also shows, the walls outer protrusions 27 may have a straight aligned portion, the bracelet being oriented in the preferred direction at the bottom of the watch case, with the walls of the groove 26 in order to reinforce the need to orient the parts correctly to be able to assemble or disassemble the bracelet.

Pour détacher un bracelet de la boíte de montre 2, l'utilisateur doit pousser simultanément les deux poussoirs 20 et orienter le bracelet perpendiculairement vers le bas par rapport à la boíte de montre. En appuyant sur les poussoirs, il enfonce les contre-pivots 21 ce qui rétracte les pivots 8, 9 dans le gond 1 (voir figure 2). En tirant sur le bracelet dans l'axe de ce dernier qui se trouve dans l'orientation privilégiée pour cette opération, on sépare alors l'élément de liaison 3 du gond 1 du fait que la protubérance 27 peut quitter le logement annulaire 25 et le bracelet est désolidarisé de la boíte de montre 2. Du fait qu'il faut appuyer simultanément sur les deux poussoirs 20 et orienter le bracelet perpendiculairement vers le bas, ce qui n'est possible que si la montre n'est pas sur le poignet, on obtient ainsi une double sécurité. En même temps, cette opération ne nécessite pas d'outil et permet donc au propriétaire de la montre de changer le bracelet de sa montre à tout moment.To detach a strap from watch case 2, the user must push simultaneously the two pushers 20 and orient the bracelet perpendicularly down from the watch case. By pressing the pushers, it presses the counter-pivots 21 which retracts the pivots 8, 9 in the hinge 1 (see figure 2). By pulling the bracelet in the axis of the latter which is in the preferred orientation for this operation, the connecting element 3 is then separated hinge 1 because the protuberance 27 can leave the annular housing 25 and the strap is detached from the watch case 2. Because it must be pressed simultaneously on the two pushers 20 and orient the bracelet perpendicularly downward, which is only possible if the watch is not double security on the wrist. At the same time, this operation requires no tools and therefore allows the watch owner to change the strap of your watch at any time.

Pour assembler un bracelet à la boíte de montre l'utilisateur présente l'élément de liaison 3 en dessous du gond 1. En orientant le bracelet de façon susmentionnée et représentée à la figure 3, les protubérances 27 peuvent être introduites dans les logements annulaires 25, les saignées de guidage 28 étant engagées sur les pivots 8, 9 sortant du gond 1. L'utilisateur force ensuite l'élément de fixation 3 sur le gond, les plans inclinés des saignées de guidage 28 font se rétracter les pivots 8, 9 jusqu'au moment ou les évidements centraux 29 sont en regard de ces pivots 8, 9 et que ceux-ci rentrent dans ces évidements 29 sous l'action du ressort 10. Le bracelet est ainsi solidarisé à la boíte de montre.To assemble a bracelet to the watch case, the user presents the connecting element 3 below the hinge 1. By orienting the bracelet so above and shown in Figure 3, the protrusions 27 can be introduced into the annular housings 25, the guide grooves 28 being engaged on the pivots 8, 9 leaving the hinge 1. The user then forces the element fixing 3 on the hinge, the inclined planes of the guide grooves 28 are retract the pivots 8, 9 until the central recesses 29 are in look of these pivots 8, 9 and that they enter these recesses 29 under the action of the spring 10. The strap is thus secured to the watch case.

Grâce à ce dispositif de fixation, on peut facilement et rapidement, notamment sans outil, changer son bracelet de montre, ceci tout en étant sûr d'une bonne liaison entre le bracelet et la boíte de montre.Thanks to this fixing device, we can easily and quickly, especially without tools, change your watch strap, while being sure a good connection between the bracelet and the watch case.
