Description

La présente invention concerne une boîte de montre-bracelet.The present invention relates to a wristwatch box.

Les boîtes de montre-bracelet comprennent généralement, notamment, une carrure interposée entre une lunette et un fond et des organes saillants, tels que des cornes ou des gonds, pour la fixation à un bracelet.The wristwatch boxes generally include, inter alia, a middle part interposed between a bezel and a bottom and protruding members, such as horns or hinges, for attachment to a bracelet.

Dans ces boîtes de montre-bracelet, les organes saillants de fixation au bracelet sont en général définis par la carrure. Ceci limite le nombre de matières possibles pour ladite carrure. En effet, celle-ci doit être faite dans une matière qui puisse être facilement usinée pour produire la forme des organes de fixation. La forme et les dimensions de la carrure sont en outre nécessairement dépendantes de celles des organes de fixation. Enfin, la présence de ces organes de fixation peut rendre certaines parties de la carrure difficilement accessibles pour les opérations de finition telles que le polissage, le satinage, le sablage, etc.In these wristwatch boxes, the protruding fasteners to the bracelet are generally defined by the middle part. This limits the number of possible materials for said middle. Indeed, it must be made in a material that can be easily machined to produce the shape of the fasteners. The shape and dimensions of the caseband are furthermore necessarily dependent on those of the fasteners. Finally, the presence of these fasteners can make some parts of the case difficult to access for finishing operations such as polishing, satin finishing, sanding, etc.

On connaît par le brevet CH 188 833 une boîte de montre-bracelet comprenant une carrure-lunette, un fond et des gonds de fixation à un bracelet, dans laquelle les gonds sont définis en partie par la carrure-lunette et en partie par le fond. Dans certains modes de réalisation, les parties de gond définies par la carrure-lunette et celles définies par le fond sont assemblées élastiquement par des organes de retenue. Un inconvénient de cette boîte est que les gonds sont peu robustes. Le risque est en effet élevé que les parties de gond définies par la carrure-lunette et celles définies par le fond se séparent sous l'effet d'efforts de traction ou de chocs.We know by the patent CH 188 833 a wristwatch box comprising a middle-bezel, a bottom and hinges for attachment to a bracelet, wherein the hinges are defined in part by the middle-bezel and partly by the bottom. In some embodiments, the hinge portions defined by the middle-bezel and those defined by the bottom are resiliently assembled by retaining members. A disadvantage of this box is that the hinges are not robust. The risk is indeed high that the parts of hinge defined by the middle-bezel and those defined by the bottom separate under the effect of tensile forces or shocks.

La présente invention vise à proposer une botte de montre-bracelet qui autorise une grande liberté dans la réalisation de la carrure sans nuire à la robustesse des organes de fixation au bracelet.The present invention aims to provide a wristwatch boot that allows great freedom in the realization of the middle without harming the robustness of the fasteners to the bracelet.

A cette fin il est prévu une boîte de montre-bracelet selon la revendication 1 annexée, c'est-à-dire une boîte de montre-bracelet comprenant un élément' supérieur, un élément inférieur, une carrure située entre les éléments supérieur et inférieur et des organes saillants pour la fixation à un bracelet, des premières parties de ces organes de fixation saillants étant définies par l'élément supérieur et des secondes parties de ces organes de fixation saillants étant définies par l'élément inférieur, lesdites premières et secondes parties comprenant respectivement des premiers et seconds organes de retenue qui coopèrent pour assembler lesdites premières et secondes parties, caractérisée en ce que les éléments supérieur et inférieur sont agencés pour, lors de l'assemblage de la boîte, pouvoir tourner l'un par rapport à l'autre autour de l'axe de la boîte d'une position où les premiers et seconds organes de retenue ne coopèrent pas à une position où ils coopèrent.For this purpose there is provided a wristwatch box according to claim 1 attached, that is to say a wristwatch box comprising an upper element, a lower element, a middle part between the upper and lower elements. lower and protruding members for attaching to a bracelet, the first parts of these protruding fasteners being defined by the upper member and second portions of these projecting fasteners being defined by the lower member, said first and second parts respectively comprising first and second retaining members which cooperate to assemble said first and second parts, characterized in that the upper and lower elements are arranged for, when assembling the box, to be able to rotate relative to the other around the axis of the box a position where the first and second retainers do not cooperate at a position where they cooperate.

Des modes de réalisation particuliers de l'invention sont définis dans les revendications dépendantes annexées 2 à 10.Particular embodiments of the invention are defined in the appended dependent claims 2 to 10.

En référence aux figures 1 à 5, une boîte de montre-bracelet selon l'invention comprend une carrure 1 interposée entre un cerclage supérieur 2 et un cerclage inférieur 3, une lunette en deux parties 4, 5 disposée sur la carrure 1 et sur le cerclage supérieur 2, une glace 6 montée dans la lunette 4, 5 et un fond 7 monté dans le cerclage inférieur 3. Les deux parties de la lunette sont respectivement une partie interne métallique 4 et une partie externe 5 qui est de préférence dans une autre matière, par exemple en céramique, collée sur la partie interne 4. Le fond 7 est par exemple une glace, comme représenté. La carrure 1 s'appuie sur le cerclage inférieur 3 et entoure un rebord intérieur 8 de celui-ci. Sur la partie intérieure de sa face supérieure, la carrure 1 comprend une saillie annulaire 9 qui définit des bossages radiaux 10. Le cerclage supérieur 2 repose sur la partie extérieure de la face supérieure de la carrure 1, autour de la saillie annulaire 9, et comporte des encoches 11 qui reçoivent les bossages 10. La lunette 4, 5 repose en partie sur la saillie annulaire 9 et en partie sur le cerclage supérieur 2. Des joints 12 à 15 entre la glace 6 et la lunette 4, 5, entre la lunette 4, 5 et la carrure 1, entre la carrure 1 et le cerclage inférieur 3 et entre le cerclage inférieur 3 et le fond 7 assurent l'étanchéité de la boîte.With reference to Figures 1 to 5 , a wristwatch box according to the invention comprises a middle part 1 interposed between an upper strapping 2 and a lower strapping 3, a bezel in two parts 4, 5 disposed on the middle part 1 and on the upper strapping 2, an ice-cream 6 mounted in the bezel 4, 5 and a bottom 7 mounted in the lower strapping 3. The two parts of the bezel are respectively an inner metal part 4 and an outer part 5 which is preferably in another material, for example ceramic, glued on the inner part 4. The bottom 7 is for example an ice, as shown. The middle 1 rests on the lower strapping 3 and surrounds an inner rim 8 thereof. On the inner part of its upper face, the caseband 1 comprises an annular projection 9 which defines radial bosses 10. The upper band 2 rests on the outer part of the upper face of the caseband 1, around the annular projection 9, and comprises notches 11 which receive the bosses 10. The bezel 4, 5 rests partly on the annular projection 9 and partly on the upper strapping 2. Seals 12 to 15 between the glass 6 and the bezel 4, 5, between the bezel 4, 5 and the middle part 1, between the middle 1 and the lower strapping 3 and between the lower strapping 3 and the bottom 7 seal the box.

Dans la présente invention, les organes de fixation au bracelet ne sont pas définis par la carrure 1 mais en partie par le cerclage supérieur 2 et en partie par le cerclage inférieur 3. Dans l'exemple représenté, ces organes de fixation sont sous la forme de deux paires de cornes 16 dont les parties définies par le cerclage inférieur 3, désignées par le repère 17, comprennent des orifices 18 destinés à recevoir les extrémités de barrettes de bracelet et dont les parties définies par le cerclage supérieur 2, désignées par le repère 19, recouvrent la partie supérieure des parties 17.In the present invention, the fastening members of the bracelet are not defined by the middle part 1, but partly by the upper strapping 2 and partly by the lower strapping 3. In the example shown, these fasteners are in the form of two pairs of horns 16 whose parts defined by the lower band 3, designated by the mark 17, comprise orifices 18 intended to receive the ends of bracelet bars and whose parts defined by the upper band 2, designated by the reference mark 19, cover the upper part of parts 17.

Les parties de corne 19 définies par le cerclage supérieur 2 comprennent chacune à leur extrémité distale un crochet 20 orienté vers l'intérieur de la botte et dans un plan perpendiculaire à l'axe A de la boîte. Ce crochet 20 coopère avec une entaille 21 pratiquée dans la face extérieure de la partie de corne 17 correspondante définie par le cerclage inférieur 3 pour assembler les parties de corne 17, 19. Ce crochet 20 et cette entaille 21 constituent des organes de retenue qui empêchent les parties de corne 17, 19 de se séparer l'une de l'autre dans la direction de l'axe A de la boîte par déformation sous l'effet d'un choc, par exempte, et qui limitent la déformation de la partie de corne 17 sous l'effet d'un effort de traction exercé par le bracelet. Les parties de corne 19, avec leurs crochets 20, apportent ainsi de la rigidité aux parties de corne 17 auxquelles est fixé le bracelet.The horn portions 19 defined by the upper strapping 2 each comprise at their distal end a hook 20 oriented towards the inside of the boot and in a plane perpendicular to the axis A of the box. This hook 20 cooperates with a notch 21 formed in the outer face of the corresponding horn portion 17 defined by the lower strapping 3 to assemble the horn portions 17, 19. This hook 20 and this notch 21 constitute retaining members which prevent the horn parts 17, 19 to separate from each other in the direction of the axis A of the box by deformation under the effect of a shock, for example, and which limit the deformation of the part horn 17 under the effect of a tensile force exerted by the bracelet. The horn parts 19, with their hooks 20, thus provide rigidity to the horn parts 17 to which the bracelet is attached.

Les parties de corne 19 définies par le cerclage supérieur 2 comprennent en outre chacune une surface 20a (cf. figure 3) située dans un plan perpendiculaire à l'axe A et qui s'appuie sur une surface 21a des parties de corne 17. elle aussi située dans un plan perpendiculaire à l'axe A. Ces surfaces d'appui 20a, 21a contribuent à la robustesse des cornes 16. Elles permettent aussi aux parties de corne 17, 19 de se rejoindre avec une continuité de forme et de donner ainsi aux cornes 16 une apparence harmonieuse.The horn portions 19 defined by the upper strapping 2 each further comprise a surface 20a (cf. figure 3 ) located in a plane perpendicular to the axis A and which rests on a surface 21a of the horn portions 17. it also lies in a plane perpendicular to the axis A. These bearing surfaces 20a, 21a contribute to the robustness of the horns 16. They also allow the horn parts 17, 19 to meet with a continuity of shape and thus give the horns 16 a harmonious appearance.

La boîte est maintenue dans un état assemblé par des premières vis 22 (cf. figure 4) passant chacune dans des perçages respectifs communiquant du cerclage inférieur 3, de la carrure 1 et de la partie interne 4 de la lunette, parallèlement à l'axe A. La tête de ces vis 22 est en appui sur un épaulement défini par le perçage du cerclage inférieur 3. L'extrémité filetée de ces vis 22 coopère avec un taraudage du perçage de la partie interne 4 de la lunette. Ces vis 22 serrent les cerclages 2, 3, la carrure 1 et la lunette 4, 5 entre eux dans la direction de l'axe A et positionnent angulairement le cerclage inférieur 3, la carrure 1 et la lunette 4, 5 les uns par rapport aux autres. Le cerclage supérieur 2 est lui positionné angulairement par rapport aux autres éléments de la boîte par ses encoches 11 qui coopèrent avec les bossages 10.The box is held in a state assembled by first screws 22 (cf. figure 4 ) each passing through respective holes communicating the lower ring 3, the middle part 1 and the inner part 4 of the bezel, parallel to the axis A. The head of these screws 22 bears on a shoulder defined by the drilling lower strapping 3. The threaded end of these screws 22 cooperates with a tapping of the bore of the inner part 4 of the telescope. These screws 22 tighten the straps 2, 3, the middle part 1 and the bezel 4, 5 between them in the direction of the axis A and angularly position the lower strapping 3, the middle part 1 and the bezel 4, 5 relative to each other. to others. The upper strapping 2 is positioned angularly relative to the other elements of the box by its notches 11 which cooperate with the bosses 10.

Comme représenté à la figure 5, des secondes vis 23 sont également prévues qui passent chacune dans des perçages respectifs communiquant d'une partie de corne 17 définie par le cerclage inférieur 3 et de la partie de corne 19 correspondante définie par le cerclage supérieur 2. Ces secondes vis 23 aident à maintenir les parties de cornes 17, 19 solidement fixées les unes aux autres, en complément de la coopération entre les crochets 20 et les entailles 21. Grâce à la coopération entre les crochets 20 et les entailles 21, ces secondes vis 23 subissent peu de contraintes lors d'efforts exercés sur les parties de corne 17, 19. Ces secondes vis 23 ne sont néanmoins pas indispensables et pourraient donc, dans une variante, être supprimées.As represented in figure 5 , second screws 23 are also provided which each pass through respective holes communicating a horn portion 17 defined by the lower strapping 3 and the corresponding horn portion 19 defined by the upper strapping 2. These second screws 23 help to maintaining the parts of horns 17, 19 firmly fixed to each other, in addition to the cooperation between the hooks 20 and the notches 21. Thanks to the cooperation between the hooks 20 and the notches 21, these second screws 23 undergo few constraints during efforts exerted on the horn parts 17, 19. These second screws 23 are nevertheless not essential and could therefore, in a variant, be removed.

Les cerclages supérieur et inférieur 2, 3 sont typiquement faits en métal. La carrure 1, elle, peut être faite dans d'autres matières. En particulier, comme elle ne comporte pas les cornes 16, la carrure 1 peut être faite dans des matières difficilement usinables telles que les matières composites à renfort en fibres de carbone et à matrice en résine époxy ou le saphir. On notera de plus que l'absence de cornes sur la carrure 1 rend facilement accessible toute la surface de la carrure 1 pour un travail de finition du type polissage, satinage ou sablage, par exemple.The upper and lower straps 2, 3 are typically made of metal. The middle 1, it can be made in other materials. In particular, since it does not include the horns 16, the middle part 1 can be made in difficultly machinable materials such as composite materials with carbon fiber reinforcement and epoxy resin matrix or sapphire. Note further that the absence of horns on the middle 1 makes easily accessible the entire surface of the caseband 1 for finishing work of the type polishing, satin or sandblasting, for example.

Conformément à la présente invention, les cerclages 2, 3 sont agencés pour pouvoir tourner l'un par rapport à l'autre autour de l'axe A lors de l'assemblage de la botte, avant que les premières et secondes vis 22, 23 aient été introduites. Ainsi, comme représenté à la figure 6, l'assemblage de la boîte s'effectue dans un premier temps en appliquant les cerclages 2, 3 de part et d'autre de la carrure 1 (non représentée à la figure 6 pour des raisons de clarté) dans des positions angulaires respectives différentes qui sont telles que les crochets 20 sont en dehors des entailles 21. Puis, on fait tourner les cerclages 2, 3 l'un par rapport à l'autre autour de l'axe A jusqu'à faire entrer les crochets 20 dans les entailles 21, les parties de corne 17, 19 formant alors ensemble les cornes 16 de la boîte (figure 7). Pendant cette rotation, la carrure 1 est solidaire du cerclage supérieur 2 du fait de la coopération entre les encoches 11 et les bossages 10 et est guidée dans sa rotation par rapport au cerclage inférieur 3 par le rebord intérieur 8. Ensuite, on applique la lunette 4, 5 sur la carrure 1 et le cerclage supérieur 2 et on fixe le tout au moyen des vis 22, 23.According to the present invention, the straps 2, 3 are arranged to be rotatable relative to each other about the axis A during assembly of the boot, before the first and second screws 22, 23 have been introduced. Thus, as represented in figure 6 , the assembly of the box is carried out initially by applying the strapping 2, 3 on either side of the caseband 1 (not shown in FIG. figure 6 for reasons of clarity) in respective different angular positions which are such that the hooks 20 are outside the notches 21. Then, the strings 2, 3 are rotated relative to each other about the axis A to bring the hooks 20 into the notches 21, the horn parts 17, 19 then forming together the horns 16 of the box ( figure 7 ). During this rotation, the middle part 1 is integral with the strapping upper 2 because of the cooperation between the notches 11 and bosses 10 and is guided in its rotation relative to the lower strapping 3 by the inner rim 8. Then, the bezel 4, 5 is applied to the middle 1 and the upper strapping 2 and fixed all by means of the screws 22, 23.

Avec ce mode d'assemblage des cerclages 2, 3, aucune déformation élastique des parties de corne 17, 19 n'est nécessaire pour introduire les crochets 20 dans les entailles 21. Les parties de corne 17, 19 peuvent donc être robustes. Un léger jeu peut être prévu entre les crochets 20 et les parois des entailles 21 pour permettre aux crochets 20 de venir se placer dans les entailles 21 sans subir de contraintes. Dans une variante, on peut prévoir que l'introduction des crochets 20 dans les entailles 21 par la rotation relative des cerclages 2, 3 entraîne une légère déformation élastique des parties de corne 17, 19 et un léger serrage des crochets 20 contre une paroi des entailles 21. Dans une autre variante, on peut prévoir des organes d'encliquetage sur les parties de corne 17, 19 ou sur les cerclages 2, 3 et la carrure 1 pour arrêter les cerclages 2, 3 dans leur position angulaire finale permettant l'introduction des vis 22, 23.With this method of assembling the rings 2, 3, no elastic deformation of the horn portions 17, 19 is necessary to introduce the hooks 20 in the notches 21. The horn parts 17, 19 can be robust. A slight clearance can be provided between the hooks 20 and the walls of the notches 21 to allow the hooks 20 to be placed in the notches 21 without being stressed. In a variant, provision can be made for the introduction of the hooks 20 in the notches 21 by the relative rotation of the straps 2, 3 to cause a slight elastic deformation of the horn parts 17, 19 and a slight tightening of the hooks 20 against a wall of the Notches 21. In another variant, it is possible to provide detent members on the horn portions 17, 19 or on the straps 2, 3 and the middle part 1 to stop the straps 2, 3 in their final angular position allowing the introducing the screws 22, 23.

Avantageusement, les surfaces des parties de corne 17,19 susceptibles d'être en contact pendant la rotation des cerclages 2, 3 l'un par rapport à l'autre sont des parties de surfaces de révolution autour de l'axe A. Ces surfaces de contact sont notamment, pour les parties de corne 19, les surfaces intérieures désignées par le repère 24 (cf. figures 3 et 6), en particulier la surface d'extrémité du crochet 20, et pour les parties de corne 17, les surfaces extérieures désignées par le repère 25, en particulier la surface du fond des entailles 21. Toutes ces surfaces peuvent être obtenues par une opération de tournage. Grâce à ces surfaces de révolution 24, 25, le jeu radial entre les cerclages 2, 3 peut être faible et l'ajustement peut être précis.Advantageously, the surfaces of the horn portions 17, 19 which may be in contact during the rotation of the straps 2, 3 with respect to each other are parts of surfaces of revolution about the axis A. These surfaces in particular, for the horn parts 19, the internal surfaces designated by the reference 24 (cf. figures 3 and 6 ), in particular the end surface of the hook 20, and for the horn parts 17, the outer surfaces designated by the reference 25, in particular the bottom surface of the notches 21. All these surfaces can be obtained by a shooting. With these surfaces of revolution 24, 25, the radial clearance between the straps 2, 3 can be low and the adjustment can be accurate.

La présente invention a été décrite ci-dessus uniquement à titre d'exemple. Il va de soi que des modifications pourraient être faites sans sortir du cadre de l'invention revendiquée. Par exemple, bien qu'il soit préférable, pour autoriser une plus grande liberté dans la réalisation de carrure 1, que celle-ci soit une pièce distincte des cerclages supérieur et inférieur 2, 3, comme dans l'exemple représenté, cette carrure 1 pourrait être monobloc avec l'un des cerclages supérieur et inférieur 2, 3. De manière similaire, l'utilisation des cerclages supérieur et inférieur 2, 3 en tant que pièces distinctes de la lunette 4, 5 et du fond 7 permet une plus grande liberté dans la réalisation de la lunette 4, 5 et du fond 7, mais en variante ces cerclages supérieur et inférieur 2, 3 pourraient être monobloc avec la lunette 4, 5, plus précisément avec la partie interne 4 de celle-ci, et avec le fond 7, respectivement. Par ailleurs, les parties de corne 17, 19 pourraient être inversées. En d'autres termes, les parties de corne 17 définies par le cerclage inférieur 3 pourraient recouvrir les parties de corne 19 définies par le cerclage supérieur 2. Dans ce cas, les orifices 18 de réception des barrettes de bracelet seraient formés dans les parties de corne 19. De plus, la boîte et notamment la carrure 1 peuvent avoir diverses formes autres que circulaire. Dans ce cas, les cerclages supérieur et inférieur 2, 3 seront remplacés par des éléments de forme adaptée à la boîte mais remplissant les fonctions décrites ci-dessus. On peut également avoir un mélange de formes avec, par exemple, une carrure circulaire et des éléments supérieur et inférieur ayant une périphérie intérieure circulaire mais une périphérie extérieure non circulaire, par exemple carrée, rectangulaire ou en forme de tonneau.The present invention has been described above by way of example only. It goes without saying that modifications could be made without departing from the scope of the claimed invention. For example, although it is preferable, to allow a greater freedom in the realization of middle 1, that it is a separate part of the upper and lower strapping 2, 3, as in the example shown, this middle part 1 could be monobloc with one of the upper and lower strapping 2 3. Similarly, the use of the upper and lower strapping 2, 3 as separate parts of the bezel 4, 5 and the bottom 7 allows greater freedom in the realization of the bezel 4, 5 and the bottom 7, but alternatively these upper and lower rims 2, 3 could be integral with the bezel 4, 5, more precisely with the inner portion 4 thereof, and with the bottom 7, respectively. Moreover, the horn parts 17, 19 could be reversed. In other words, the horn portions 17 defined by the lower strapping 3 could cover the horn portions 19 defined by the upper strapping 2. In this case, the receiving orifices 18 of the bracelet straps would be formed in the parts of the straps. horn 19. In addition, the box and in particular the caseband 1 may have various forms other than circular. In this case, the upper and lower strapping 2, 3 will be replaced by shaped elements adapted to the box but fulfilling the functions described above. One can also have a mixture of shapes with, for example, a circular middle and upper and lower elements having a circular inner periphery but a non-circular outer periphery, for example square, rectangular or barrel-shaped.
