Description

La présente invention concerne une boîte de montre munie d'une lunette tournante notamment une boîte de montre-bracelet.The present invention relates to a watch case provided with a rotating bezel, in particular a wristwatch box.

Un élément important de l'habillement d'une montre-bracelet est le bracelet permettant de la fixer autour du poignet, de même pour une montre-médaillon c'est la chaînette par laquelle elle est suspendue autour du cou ou pour les montres du type broche suspendue par un lien souple destiné à être accroché sur un vêtement, la chaînette ou le lien souple constitue un des éléments esthétiques de la montre. L'évolution des moeurs et de la mode a créé de nouveaux besoins notamment en ce qui concerne le changement du bracelet voire du lien souple d'une montre-broche, ou de la chaînette d'une montre-médaillon pour l'adapter, soit aux circonstances ou à l'habillement, soit à la mode. Mis à part les montres fantaisies qui sont vendues souvent avec des bracelets de différentes couleurs associées à une lunette ou d'autres moyens permettant un changement rapide du bracelet et de la lunette qui a une couleur assortie au bracelet, les montres d'une certaine qualité utilisent toujours des moyens de fixation du bracelet conventionnels à savoir des cornes ou des protubérances avec un logement pour l'extrémité du bracelet qui est en cuir ou en métal et le changement du bracelet ne peut pas se faire instantanément par l'utilisateur. Souvent l'utilisateur doit s'adresser soit au technicien pour le changement du bracelet soit il doit utiliser un ou plusieurs outils adéquats pour effectuer le même travail.An important element of the clothing of a wristwatch is the bracelet allowing to fix it around the wrist, in the same way for a medallion watch it is the chain by which it is suspended around the neck or for the watches of the type brooch suspended by a flexible link intended to be hung on a garment, the chain or the flexible link constitutes one of the aesthetic elements of the watch. The evolution of manners and fashion has created new needs, particularly with regard to changing the bracelet or even the flexible link of a pin watch, or the chain of a medallion watch to adapt it, i.e. to circumstances or clothing, either fashionable. Apart from the fancy watches which are often sold with bracelets of different colors associated with a bezel or other means allowing a rapid change of the bracelet and the bezel which has a color matching the bracelet, watches of a certain quality always use conventional strap fixing means, namely horns or protuberances with a housing for the end of the strap which is made of leather or metal and the strap cannot be changed instantly by the user. Often the user must contact either the technician to change the bracelet or he must use one or more suitable tools to do the same job.

Un autre élément du bracelet d'une montre qui pose parfois des problèmes est la boucle, notamment concernant les bracelets métalliques, car lors de la mise en longueur en fonction du tour du poignet de l'utilisateur, il faut faire attention de raccourcir les deux brins du bracelet de la même longueur afin que la boucle soit toujours positionnée au bon endroit. Concernant les bracelets en cuir, le fait d'avoir chaque fois que l'on met ou on enlève une montre à décrocher l'extrémité d'un brin et le faire glisser dans le passant provoque une certaine usure de cette extrémité ce qui est gênant notamment lorsqu'il s'agit d'un bracelet de qualité et coûteux.Another element of the watch strap that sometimes poses problems is the buckle, especially concerning metal bracelets, because when lengthening according to the user's wrist circumference, care must be taken to shorten the two strands of the bracelet by the same length so that the buckle is always positioned in the right place. Concerning leather bracelets, the fact of having each time that one puts or one takes off a watch to unhook the end of a strand and to slide it in the passer-by causes a certain wear of this end which is annoying especially when it is a quality and expensive bracelet.

La présente invention se propose de pallier les inconvénients susmentionnés concernant le changement rapide d'un bracelet ou de tout autre lien d'une montre et/ou permettre d'éliminer les problèmes causés par les boucles conventionnelles d'une montre-bracelet.The present invention proposes to overcome the aforementioned drawbacks concerning the rapid change of a bracelet or of any other link of a watch and / or allow the problems caused by the conventional buckles of a wristwatch to be eliminated.

La boîte de montre munie d'une lunette tournante selon l'invention est caractérisée par le fait que la lunette tournante et la carrure comprennent des moyens complémentaires pour assurer la tenue et le verrouillage de l'une au moins des extrémités d'un lien, tel qu'un bracelet, et que la lunette et la carrure sont agencées de sorte à permettre le déverrouillage et verrouillage instantanés de l'extrémité dudit lien.The watch case provided with a rotating bezel according to the invention is characterized in that the rotating bezel and the middle part comprise complementary means for ensuring the holding and locking of at least one of the ends of a link, such as a bracelet, and that the bezel and the middle part are arranged so as to allow instantaneous unlocking and locking of the end of said link.

L'avantage de la boîte de montre selon l'invention, qui concerne principalement une boîte de montre-bracelet, mais également une montre-broche suspendue par un lien souple voire une montre-médaillon est que la tenue de l'une des extrémités du lien souple et de verrouillage avec la boîte sont assurés par des moyens complémentaires de la lunette tournante et de la carrure agencée pour permettre le déverrouillage et verrouillage instantanés. Ainsi, pour arriver à ce résultat, l'assemblage de la lunette tournante et de la carrure est réalisé de sorte que la lunette puisse tourner d'au moins quelques degrés autour d'un axe perpendiculaire au plan du cadran de la montre. Cet assemblage permet ainsi le verrouillage et déverrouillage de l'extrémité du lien par simple rotation de la lunette de quelques degrés, cette rotation permettant l'éloignement des moyens complémentaires ou leur rapprochement pour déverrouiller respectivement verrouiller la tenue de l'extrémité du lien notamment du bracelet.The advantage of the watch case according to the invention, which mainly concerns a wrist watch case, but also a pin watch suspended by a flexible link or even a medallion watch is that the holding of one of the ends of the flexible link and locking with the box are provided by means complementary to the rotating bezel and the middle arranged to allow instant unlocking and locking. So, to achieve this result, the assembly of the rotating bezel and the middle part is produced so that the bezel can rotate at least a few degrees around an axis perpendicular to the plane of the watch dial. This assembly thus allows the locking and unlocking of the end of the link by simple rotation of the telescope by a few degrees, this rotation allowing the removal of the complementary means or their bringing together to unlock respectively lock the holding of the end of the link, in particular of the bracelet.

Plusieurs variantes d'exécution peuvent être réalisées restant toujours dans l'esprit de l'invention c'est-à-dire la tenue et le verrouillage de l'extrémité d'un lien souple sont assurés par la collaboration des moyens complémentaires se trouvant d'une part, sur la carrure et d'autre part, sur la lunette. Leur agencement ainsi que l'assemblage de ces deux pièces étant conçus pour permettre un verrouillage et déverrouillage instantanés.Several variant embodiments can be carried out, always remaining in the spirit of the invention, that is to say holding and locking the end of a flexible link, are ensured by the collaboration of complementary means being found in on the one hand, on the middle and on the other hand, on the bezel. Their arrangement and the assembly of these two parts being designed to allow instant locking and unlocking.

Différents exemples de réalisation seront maintenant décrits à l'aide des dessins annexés.Different exemplary embodiments will now be described with the aid of the accompanying drawings.

La figure 1 est une vue schématique en plan d'une boîte de montre et des extrémités d'un bracelet en position déverrouillée.Figure 1 is a schematic plan view of a watch case and the ends of a bracelet in the unlocked position.

Les figures 2 et 3 sont des vues analogues à la précédente d'une variante d'exécution.Figures 2 and 3 are views similar to the previous of an alternative embodiment.

La figure 4 est une vue analogue aux précédentes d'une montre-bracelet avec deux paires de cornes.Figure 4 is a view similar to the preceding of a wristwatch with two pairs of horns.

La figure 5 est une vue d'une variante d'exécution de la figure 4.FIG. 5 is a view of an alternative embodiment of FIG. 4.

La figure 6 est une vue similaire aux autres d'une autre variante d'exécution.Figure 6 is a view similar to the others of another alternative embodiment.

La figure 7 est une vue en coupe 12h - 12h montrant principalement l'assemblage lunette-carrure.Figure 7 is a 12h - 12h sectional view mainly showing the bezel-caseband assembly.

Dans toutes les exécutions que nous allons décrire par la suite, la lunette est montée rotative sur la carrure de manière connue. Un exemple d'un tel assemblage sera décrit à l'aide de la figure 7.In all of the embodiments which we will describe below, the bezel is rotatably mounted on the middle in a known manner. An example of such an assembly will be described using FIG. 7.

A la figure 1 on a représenté schématiquement une carrure de montre 1 munie de deux protubérances latérales 2 et 3 chacune étant munie d'une rainure 4, 5 destinée à recevoir la tige 6 d'un brin de bracelet 7. Sur la carrure 1 est monté une lunette tournante 8 par des moyens que nous décrirons plus loin. La lunette 8 est munie également de deux protubérances latérales 9, 10 dont la forme est complémentaire aux deux protubérances 2 et 3 de la carrure.In Figure 1 there is shown schematically a watch middle 1 provided with two lateral protrusions 2 and 3 each being provided with a groove 4, 5 intended to receive the rod 6 of a bracelet strand 7. On the middle 1 is mounted a rotating bezel 8 by means which we will describe later. The bezel 8 is also provided with two lateral protuberances 9, 10 whose shape is complementary to the two protuberances 2 and 3 of the middle part.

Pour accrocher le brin d'un bracelet 7 sur la montre, on fait tourner la lunette 8 de quelques degrés de sorte à dégager les deux protubérances et notamment les deux rainures 4 et 5, on engage les tiges 6 dans les rainures et ceci pour les deux brins et on tourne la lunette 8 dans le sens contraire pour superposer les protubérances 9 et 10 sur les protubérances 4 et 5, ainsi les extrémités du bracelet sont tenues, d'une part, par les rainures 2 et 3 et, d'autre part, verrouillées par les protubérances 9 et 10.To hang the strand of a bracelet 7 on the watch, the bezel 8 is rotated a few degrees so as to release the two protrusions and in particular the two grooves 4 and 5, the rods 6 are engaged in the grooves and this for the two strands and the bezel 8 is turned in the opposite direction to superimpose the protrusions 9 and 10 on the protrusions 4 and 5, thus the ends of the bracelet are held, on the one hand, by the grooves 2 and 3 and, on the other part, locked by protrusions 9 and 10.

Par ce moyen simple, c'est-à-dire en tournant la lunette de quelques degrés, on peut effectuer très rapidement le changement d'un bracelet que ce soit un bracelet en cuir ou un bracelet métallique pour autant que ses extrémités soient munies d'une tige 6. Afin d'éviter un déverrouillage intempestif, on a prévu un moyen entre la lunette 8 et la carrure 1 empêchant la lunette 8 de tourner de manière intempestive que l'on décrira à l'aide de la figure 7 ultérieurement. Lorsqu'on veut obtenir le déverrouillage des extrémités du bracelet, il faut appliquer sur la lunette un moment de rotation relativement élevé du moins par rapport à celui qui peut subvenir de manière intempestive ou accidentelle.By this simple means, that is to say by turning the bezel a few degrees, it is very quickly possible to change a bracelet, whether it is a leather bracelet or a metallic bracelet, provided that its ends are fitted with 'a rod 6. In order to avoid untimely unlocking, a means has been provided between the bezel 8 and the middle part 1 preventing the bezel 8 from inadvertently turning, which will be described with the aid of FIG. 7 later. When one wants to obtain the unlocking of the ends of the bracelet, it is necessary to apply to the bezel a relatively high moment of rotation at least compared to that which can occur inadvertently or accidentally.

Afin d'éviter que les tiges 6 du bracelet puissent se dégager très facilement lorsque la lunette 8 est en position de déverrouillage, lesdites rainures peuvent être faites de manière à ce que leurs parois soient obliques, c'est-à-dire qu'elles rentrent dans l'épaisseur des protubérances vers leurs extrémités libres.In order to prevent the rods 6 of the bracelet from being able to disengage very easily when the bezel 8 is in the unlocked position, said grooves can be made so that their walls are oblique, that is to say that they fall into the thickness of the protrusions towards their free ends.

Aux figures 2 et 3 nous avons représenté la même boîte de montre et utilisé les mêmes références pour indiquer les mêmes éléments. Dans ce cas la lunette est munie d'une protubérance intermédiaire 11 qui peut facilement correspondre à la protubérance que l'on trouve dans certains cas protégeant la couronne de la tige de remontoir ou de mise à l'heure. Cette protubérance 11 est utile lorsqu'on veut éviter l'utilisation d'une boucle conventionnelle, ainsi pour enlever une montre portée au poignet, il suffit de tourner la lunette 8 de 90° de sorte que la protubérance 11 vienne face à la protubérance 3 ou éventuellement 2 de sorte à assurer le verrouillage d'une des deux protubérances et dégager uniquement l'une des deux, dans le cas présent celle portant la référence 2, afin de pouvoir décrocher le bracelet. On procède donc de cette manière pour enlever ou remettre une montre-bracelet autour du poignet sans avoir à utiliser une boucle.In Figures 2 and 3 we have shown the same watch case and used the same references to indicate the same elements. In this case the bezel is provided with an intermediate protuberance 11 which can easily correspond to the protuberance that is found in certain cases protecting the crown of the winding or time-setting stem. This protuberance 11 is useful when one wants to avoid the use of a conventional buckle, so to remove a watch worn on the wrist, it suffices to turn the bezel 8 by 90 ° so that the protuberance 11 comes opposite the protuberance 3 or possibly 2 so as to ensure the locking of one of the two protrusions and release only one of the two, in this case the one bearing the reference 2, in order to be able to unhook the bracelet. We therefore proceed in this way to remove or put a wristwatch around the wrist without having to use a buckle.

Il est évident que l'on pourrait également imaginer une lunette 8 munie d'une seule protubérance permettant de déverrouiller uniquement une seule extrémité du bracelet ainsi la rotation de la lunette 8 correspond à l'ouverture ou la fermeture d'une boucle de montre-bracelet.It is obvious that one could also imagine a bezel 8 provided with a single protuberance allowing only one end of the strap to be unlocked, thus the rotation of the bezel 8 corresponds to the opening or closing of a watch loop. bracelet.

A la figure 4 nous avons représenté une boîte de montre 12 munie de deux paires de cornes conventionnelles 13, 14, 15 et 16, chacune étant munie d'une encoche 17 préwe pour recevoir la tige 18 d'un bracelet de montre 19. Une lunette 20 est montée de la même manière que précédemment sur la carrure et elle est également munie de quatre projections 21, 22, 23 et 24 de forme complémentaire à celle des cornes 13 à 16 de la carrure. Après avoir mis la tige 18 dans les creusures 17 des quatre cornes, on tourne la lunette 20 de sorte que les projections 21, 22, 23 et 24 viennent se superposer sur les cornes 13, 14, 15 et 16 obtenant ainsi le verrouillage des extrémités du bracelet. Ici aussi un dispositif empêche la rotation intempestive de la lunette 20 pour éviter un déverrouillage accidentel.In FIG. 4 we have shown a watch case 12 provided with two pairs of conventional horns 13, 14, 15 and 16, each being provided with a prewept notch 17 for receiving the rod 18 of a watch strap 19. A bezel 20 is mounted in the same way as above on the middle part and it is also provided with four projections 21, 22, 23 and 24 of shape complementary to that of the horns 13 to 16 of the middle part. After having put the rod 18 in the recesses 17 of the four horns, the bezel 20 is turned so that the projections 21, 22, 23 and 24 are superimposed on the horns 13, 14, 15 and 16 thus obtaining the locking of the ends of the bracelet. Here too, a device prevents inadvertent rotation of the bezel 20 to avoid accidental unlocking.

On peut également avoir une lunette munie seulement de deux projections soit 21, 22, soit 23, 24, de sorte que la lunette tient lieu de boucle et non d'un élément permettant le changement rapide d'un bracelet.It is also possible to have a bezel provided with only two projections, either 21, 22 or 23, 24, so that the bezel takes the place of a loop and not of an element allowing the rapid change of a bracelet.

A la figure 5, nous avons représenté une autre variante d'exécution similaire à celle décrite à la figure 4, c'est-à-dire que la boîte de montre 30 est munie également de deux paires de cornes 31, 32, 33 et 34 mais cette fois les cornes diamétralement opposées 31 et 34 sont munies d'une creusure 35, 36 tandis que les cornes 32, 33 sont munies d'un trou, borgne ou non, 37, 38. Une lunette 39 est montée sur la carrure comme précédemment et elle est munie uniquement de deux projections 40, 41 de forme complémentaire aux cornes 31 et 34 munies des encoches 35, 36. Ici pour changer le bracelet il faut glisser l'une des extrémités de chaque tige dans le trou 38 et 37 et poser l'autre extrémité dans les encoches 35 et 36 qui seront verrouillées en tournant la lunette 39 de sorte que les projections 40 et 41 viennent se superposer aux cornes 31 et 34.In FIG. 5, we have represented another alternative embodiment similar to that described in FIG. 4, that is to say that the watch case 30 is also provided with two pairs of horns 31, 32, 33 and 34 but this time the diametrically opposite horns 31 and 34 are provided with a recess 35, 36 while the horns 32, 33 are provided with a hole, blind or not, 37, 38. A bezel 39 is mounted on the middle as before and it is provided only with two projections 40, 41 of complementary shape to the horns 31 and 34 provided with notches 35, 36. Here to change the bracelet, slide one end of each rod into the hole 38 and 37 and place the other end in the notches 35 and 36 which will be locked by turning the bezel 39 so that the projections 40 and 41 are superimposed on the horns 31 and 34.

A la figure 6, nous avons représenté une dernière variante d'exécution d'une boîte de montre 50 munie de deux protubérances latérales 51 et 52 munies d'une creusure en forme par exemple de queue d'aronde 53, 54 destinée à recevoir l'extrémité d'un brin de bracelet 59 de forme correspondante, tandis qu'une lunette tournante 55 est munie de deux projections 56, 57 venant se superposer sur les protubérances 51, 52 pour verrouiller comme précédemment l'extrémité du bracelet. A partir des exemples décrits précédemment on peut imaginer plusieurs variantes ne sortant pas de l'esprit de l'invention.In FIG. 6, we have shown a last alternative embodiment of a watch case 50 provided with two lateral protrusions 51 and 52 provided with a recess in the form, for example of a dovetail 53, 54 intended to receive the end of a bracelet strand 59 of corresponding shape, while a rotating bezel 55 is provided with two projections 56, 57 superimposed on the protrusions 51, 52 to lock the end of the bracelet as before. From the examples described above, it is possible to imagine several variants which do not depart from the spirit of the invention.

A la figure 7 est représentée une vue en coupe 12h-12h d'une exécution de l'invention, cette vue est surtout présentée pour montrer une exécution possible de l'assemblage de la lunette tournante sur la carrure lunette ainsi qu'un moyen empêchant la lunette tournante de tourner de manière intempestive.In Figure 7 is shown a 12h-12h sectional view of an embodiment of the invention, this view is mainly presented to show a possible execution of the assembly of the rotating bezel on the middle bezel and a means preventing the rotating bezel to rotate unexpectedly.

La boîte de montre comprend une carrure lunette 100, fermée par un fond 101, qui peut être vissé, ou chassé etc., abritant un mouvement 103 et fermé sur la partie supérieure d'un verre 104. Une lunette tournante 105 est montée sur la carrure lunette 100, l'assemblage est assuré par un ressort 106 formant une ligne polygonale et logé dans deux rainures 107 et 108 se faisant face prévues sur la lunette 105 et la carrure tournante 100.The watch case includes a bezel middle 100, closed by a bottom 101, which can be screwed on, or driven off etc., housing a movement 103 and closed on the upper part of a glass 104. A rotating bezel 105 is mounted on the middle bezel 100, the assembly is ensured by a spring 106 forming a polygonal line and housed in two grooves 107 and 108 facing each other provided on the bezel 105 and the rotating middle 100.

La carrure lunette 100 est munie d'une protubérance 109 munie d'une creusure 109a (comme par exemple celle de la tige (6) destinée à loger la tige 110 d'un brin de bracelet 111 (similaire à celui de la figure 1). La lunette 105 est munie également d'une protubérance 105a complémentaire permettant de verrouiller la tige 110 dans la creusure 109a.The middle part of the bezel 100 is provided with a protuberance 109 provided with a recess 109a (such as for example that of the rod (6) intended to accommodate the rod 110 of a bracelet strand 111 (similar to that of FIG. 1) The bezel 105 is also provided with a complementary protuberance 105a making it possible to lock the rod 110 in the recess 109a.

Bien entendu cette exécution de la lunette tournante peut s'appliquer à n'importe quelle exécution des figures précédentes (cornes, protubérances, queue d'arronde ...).Of course, this execution of the rotating bezel can be applied to any execution of the preceding figures (horns, protuberances, dovetail, etc.).

Pour permettre d'empêcher le déverrouillage intempestif de l'extrémité d'un lien on peut prévoir une ou plusieurs billes ou tétons à tête sphérique 112 chacune logée dans une douille 113 sertie dans la carrure lunette et comprenant un moyen élastique (par exemple un ressort) pour pousser la bille ou le téton dans une dépression 114 de la lunette. Ainsi, lorsque la dépression 114 se trouve face à la bille ou le téton 112, la lunette 105 ne peut pas être tournée de manière intempestive. Un moment de rotation plus important est nécessaire pour faire fermer la lunette 105 et faire sortir la bille ou le téton 112 de la dépression 114. Bien entendu d'autres moyens de verrouillage de la lunette en rotation peuvent être utilisés sans sortir de l'esprit de l'invention.To prevent inadvertent unlocking of the end of a link, one or more balls or nipples with a spherical head 112 can be provided each housed in a socket 113 set in the middle part of the bezel and comprising an elastic means (for example a spring ) to push the ball or the nipple into a depression 114 in the telescope. Thus, when the depression 114 is facing the ball or the stud 112, the bezel 105 cannot be inadvertently turned. A greater moment of rotation is necessary to close the bezel 105 and bring out the ball or the stud 112 of the depression 114. Of course other means of locking the rotating bezel can be used without going out of the mind of the invention.

Bien que nous avons décrit ici principalement des montres-bracelets, il est évident que l'invention peut être utilisée pour des montres broches suspendues par un lien souple et dans ce cas au lieu d'avoir deux protubérances ou deux paires de cornes etc... il suffit d'en avoir une seule. Le but de l'invention est de pouvoir changer le lien, pour, par exemple, l'accorder à l'habillement ou circonstance. De même, on pourrait à la place d'une montre broche avoir une montre médaillon et utiliser l'invention de la même manière.Although we have mainly described wristwatches here, it is obvious that the invention can be used for pin watches suspended by a flexible link and in this case instead of having two protrusions or two pairs of horns etc. just have one. The object of the invention is to be able to change the link, to, for example, accord it to the clothing or circumstance. Similarly, one could instead of a brooch watch have a medallion watch and use the invention in the same way.

En fonction de l'habillement de la montre des variantes d'exécution sont possibles par exemple la lunette tournante peut être munie de deux encoches, au lieu de deux protubérances, que l'on doit positionner face au logement prévu dans la carrure par les extrémités du bracelet pour obtenir le déverrouillage du bracelet.Depending on the clothing of the watch, variants are possible, for example the rotating bezel can be provided with two notches, instead of two protrusions, which must be positioned opposite the housing provided in the middle by the ends. of the bracelet to unlock the bracelet.
