Description

La présente invention concerne une boîte de montre comportant un fond vissé dont l'alignement peut être ajusté par rapport à un axe vertical 12 heures-6 heures. La présente invention concerne également un procédé de fixation d'un fond sur une boite de montre et, plus particulièrement, un procédé permettant l'orientation d'un fond de boîte de montre par rapport à cette boite.The present invention relates to a watch case having a screwed bottom whose alignment can be adjusted with respect to a vertical axis 12 hours-6 hours. The present invention also relates to a method of fixing a bottom on a watch case and, more particularly, a method for orienting a watch case back with respect to this box.

Il arrive fréquemment que, lors du vissage d'un fond de boite de montre sur la carrure de cette dernière, on s'aperçoive que, lorsque le fond est complètement vissé, les inscriptions ou motifs décoratifs qui peuvent avoir été par exemple frappés par étampage ou gravés sur la face du fond située du côté du poignet du porteur de la montre, ne sont pas convenablement alignés par rapport à l'axe vertical 12 heures-6 heures de ladite montre, ce qui, bien entendu, nuit à l'aspect esthétique de cette montre.It often happens that, when screwing a watch case back on the middle part of the case, it is noticed that, when the bottom is completely screwed, the inscriptions or decorative motifs which may have been for example struck by stamping or engraved on the face of the bottom located on the wrist side of the wearer of the watch, are not properly aligned with respect to the vertical axis 12 o'clock-6 o'clock of said watch, which, of course, damages the appearance aesthetic of this watch.

Ce défaut d'aspect, s'il peut être toléré pour des montres bon marché, constitue un inconvénient très gênant pour des montres plus onéreuses.This lack of appearance, if it can be tolerated for cheap watches, is a disadvantage very troublesome for more expensive watches.

Pour remédier à cet inconvénient, une solution connue à ce jour consiste à apparier un fond avec une boite de montre déterminée lors de l'usinage, de façon que l'on soit assuré qu'une fois complètement vissé, le fond soit parfaitement aligné avec l'axe 12 heures-6 heures de la montre. Cette solution n'est toutefois que peu satisfaisante car on s'expose à des problèmes si jamais le fond d'origine de la montre est perdu ou abîmé et qu'il est nécessaire de le remplacer par un autre fond dont on n'est pas sûr qu'une fois vissé sur la carrure, il s'aligne toujours convenablement avec l'axe vertical 12 heures-6 heures.To remedy this drawback, a known solution to date consists in matching a bottom with a watch case determined during the machining, so that it is ensured that once completely screwed, the bottom is perfectly aligned with the 12 o'clock-6 o'clock axis of the watch. This solution, however, is unsatisfactory because we are exposed to problems if the original background of the watch is lost or damaged and it is necessary to replace it with another background which is not sure that once screwed on the middle part, it always aligns well with the vertical axis 12 hours-6 hours.

On connait également du document US 2003-016591 une boîte de montre comportant un dispositif de fixation d'un fond conforme au préambule de la revendication 1 du brevet.We also know of the document US 2003-016591 a watch case comprising a device for fixing a base according to the preamble of claim 1 of the patent.

La présente invention a pour but de remédier à cet inconvénient ainsi qu'à d'autres encore en proposant un système permettant, après vissage d'un fond sur la carrure d'une boîte de montre, de régler de manière simple et efficace l'alignement de ce fond par rapport à l'axe 12 heures-6 heures de la montre, de façon à garantir une disposition convenable des inscriptions et autres motifs décoratifs qui ont été reportés sur la face du fond de la montre dirigée du côté du poignet du porteur de cette montre.The present invention aims to overcome this disadvantage as well as others by proposing a system allowing, after screwing a bottom on the middle of a watch case, to simply and efficiently adjust the alignment of this bottom with respect to the axis 12 o'clock-6 o'clock of the watch, so as to ensure a suitable arrangement of inscriptions and other decorative motifs that have been reported on the face of the bottom of the wrist-led watch on the wrist side. bearer of this watch.

A cet effet, la présente invention concerne une boîte de montre conforme à la revendication 1 du brevet.For this purpose, the present invention relates to a watch case according to claim 1 of the patent.

Grâce à ces caractéristiques, quand le fond est vissé en butée contre la carrure et que l'on continue de visser le fond, l'élément intermédiaire qui relie le fond à la carrure peut se dévisser par rapport au fond étant donné que l'élément intermédiaire est vissé sur la carrure avec un filetage dont le sens est opposé à celui du filetage qui relie l'élément intermédiaire au fond. L'élément intermédiaire peut donc se déplacer verticalement le long du filetage de la carrure, ce qui permet une orientation aisée du fond lorsque l'ensemble fond/élément intermédiaire est vissé en butée sur la carrure.Thanks to these characteristics, when the bottom is screwed in abutment against the middle part and that one continues to screw the bottom, the intermediate element which connects the bottom to the middle part can unscrew with respect to the bottom since the element intermediate is screwed on the middle with a thread whose direction is opposite to that of the thread which connects the intermediate element to the bottom. The intermediate element can thus move vertically along the thread of the middle part, which allows easy orientation of the bottom when the bottom assembly / intermediate element is screwed abutting on the middle part.

La présente invention procure ainsi un dispositif de fixation d'un fond de boîte de montre qui permet de visser complètement ce fond sur la carrure de la montre de façon à assurer l'étanchéité de cette dernière et à éviter au maximum tout risque de perdre ledit fond, puis de pivoter ce fond par rapport à la carrure pour aligner des inscriptions ou motifs appliqués sur la face visible dudit fond par exemple par rapport à l'axe 12 heures-6 heures de la montre. On notera que cette boîte ne nécessite que peu d'adaptations par rapport à la construction d'une boîte de montre classique et qu'une seule pièce intermédiaire supplémentaire.The present invention thus provides a device for fixing a watch case back which allows the bottom to be completely screwed to the middle part of the watch so as to seal the latter and to avoid as much as possible the risk of losing said bottom, then pivot this bottom relative to the middle to align inscriptions or patterns applied to the visible face of said bottom for example with respect to the axis 12 o'clock-6 o'clock of the watch. Note that this box requires only a few adaptations compared to the construction of a conventional watch case and only one additional intermediate piece.

Les problèmes de l'art antérieur sont ainsi résolus. En particulier, on n'est plus obligé d'usiner les fonds et les carrures par paires avec une grande précision afin d'être assuré qu'au montage, lorsque qu'un fond est complètement vissé sur la carrure qui lui correspond, ce fond sera convenablement aligné par rapport à l'axe 12 heures-6 heures de la montre. En réduisant les exigences liées à la précision avec laquelle fonds et carrures doivent être usinés, la présente invention permet donc de réduire de manière sensible les coûts de fabrication et de limiter le nombre de pièces qui doivent être écartées en raison de défauts d'usinage, ce qui a, bien entendu, un impact favorable sur le prix de revient de la montre terminée.The problems of the prior art are thus solved. In particular, we are no longer obliged to machine the backs and squares in pairs with great precision to ensure that assembly, when a background is completely screwed on the middle part that corresponds to it, this background will be properly aligned with the 12 to 6 o'clock axis of the watch. By reducing the requirements related to the precision with which the backs and sides have to be machined, the present invention therefore makes it possible to significantly reduce manufacturing costs and to limit the number of parts that must be discarded because of machining defects. which has, of course, a favorable impact on the cost price of the finished watch.

Selon une autre caractéristique de l'invention, la boîte comprend en outre des moyens pour augmenter le couple de friction entre l'élément intermédiaire et le fond, ces moyens comprenant de préférence un anneau élastique interposé entre l'élément intermédiaire et le fond. Grâce à cette augmentation du couple de friction, on évite que se produise un dévissage prématuré de l'élément intermédiaire par rapport au fond lors du vissage de l'ensemble fond/élément intermédiaire sur la carrure.According to another characteristic of the invention, the box further comprises means for increasing the friction torque between the intermediate element and the bottom, these means preferably comprising an elastic ring interposed between the intermediate element and the bottom. With this increase in the friction torque, it avoids the occurrence of premature unscrewing of the intermediate element relative to the bottom during screwing of the bottom / intermediate element assembly on the middle part.

Selon un mode de réalisation préféré de l'invention, l'élément intermédiaire comprend une bague munie d'une ouverture circulaire intérieure et d'une portion d'un premier diamètre suivie d'une portion ayant un deuxième diamètre inférieur au premier diamètre suivie d'une portion ayant un deuxième diamètre inférieur au premier diamètre. En outre, la première portion filetée est ménagée dans la paroi délimitant l'ouverture de l'élément intermédiaire, la deuxième portion filetée étant ménagée sur la surface de la portion de plus grand diamètre de la bague. La face du fond dirigée vers l'intérieur de la boîte comprend une rainure annulaire dont une des parois verticales comprend un filetage destiné à coopérer avec ladite première portion filetée de l'élément intermédiaire, et la largeur de la rainure est dimensionnée pour recevoir la portion de diamètre inférieur de la bague. Dans ce mode préféré, la portion de diamètre inférieur de la bague comprend une gorge annulaire dans laquelle est disposé ledit anneau élastique qui est destiné à coopérer en frottement contre la paroi de la rainure annulaire située en regard de sa paroi comprenant le filetage.According to a preferred embodiment of the invention, the intermediate element comprises a ring provided with an inner circular opening and a portion of a first diameter followed by a portion having a second diameter smaller than first diameter followed by a portion having a second diameter smaller than the first diameter. In addition, the first threaded portion is formed in the wall defining the opening of the intermediate element, the second threaded portion being formed on the surface of the portion of larger diameter of the ring. The face of the bottom directed towards the inside of the box comprises an annular groove, one of the vertical walls comprises a thread intended to cooperate with said first threaded portion of the intermediate element, and the width of the groove is dimensioned to receive the portion of lower diameter of the ring. In this preferred embodiment, the portion of smaller diameter of the ring comprises an annular groove in which is disposed said elastic ring which is intended to cooperate in friction against the wall of the annular groove located opposite its wall comprising the thread.

Selon une caractéristique avantageuse de l'invention, la hauteur de la portion de diamètre supérieur de la bague est inférieure à la hauteur de la portion de diamètre inférieur de la bague et la profondeur de la rainure annulaire du fond est supérieure ou égale à la hauteur de la portion de diamètre inférieur de la bague.According to an advantageous characteristic of the invention, the height of the upper diameter portion of the ring is less than the height of the lower diameter portion of the ring and the depth of the annular groove of the bottom is greater than or equal to the height. the lower diameter portion of the ring.

L'invention a également pour objet un procédé d'orientation d'un fond de boîte de montre sur la carrure, caractérisé en ce qu'il comprend les étapes de:

  • se munir d'un fond présentant une portion filetée selon un premier sens;
  • se munir d'une carrure de boîte de montre comprenant une portion filetée selon un deuxième sens opposé au sens du filetage du fond;
  • se munir d'un élément intermédiaire présentant une première portion filetée destinée à coopérer avec la portion filetée du fond et une deuxième portion filetée destinée à coopérer avec la portion de la carrure;
  • visser l'élément intermédiaire sur le fond au moyen de ladite première portion filetée jusqu'en butée;
  • visser l'ensemble fond/élément intermédiaire sur la carrure au moyen de ladite deuxième portion filetée de manière que le fond vienne en butée avec la carrure, et
  • continuer de tourner le fond jusqu'à l'orientation désirée par rapport à la carrure, provoquant ainsi un déplacement vertical de l'élément intermédiaire par rapport au fond.
The subject of the invention is also a method of orienting a watch case back on the middle part, characterized in that it comprises the steps of:
  • provide a bottom having a threaded portion in a first direction;
  • provide a watch case middle including a threaded portion in a second direction opposite the direction of the thread of the bottom;
  • provide an intermediate element having a first threaded portion for cooperating with the threaded portion of the bottom and a second threaded portion for cooperating with the portion of the middle part;
  • screwing the intermediate element on the bottom by means of said first threaded portion as far as the stop;
  • screwing the bottom / intermediate element assembly on the middle part by means of said second threaded portion so that the bottom abuts with the middle part, and
  • continue to turn the bottom to the desired orientation relative to the middle part, thus causing a vertical displacement of the intermediate element relative to the bottom.

La présente invention procède de l'idée générale inventive qui consiste à visser un fond non plus directement sur la carrure d'une boîte de montre, mais à l'aide d'un élément intermédiaire vissé respectivement sur le fond et la carrure au moyen de deux filetages ayant des pas de sens opposés. Ainsi, lorsque le fond est vissé en butée sur la carrure, le fond peut encore être pivoté par rapport à la carrure de la montre afin de régler son alignement par exemple par rapport à l'axe vertical 12 heures-6 heures de ladite montre. Ceci est rendu possible grâce au déplacement de l'élément intermédiaire le long du filetage de la carrure, déplacement autorisé par l'arrangement des deux filetages à pas de sens opposés. Grâce à ces caractéristiques, la présente invention procure en outre une boîte de montre dont la carrure et le fond ne nécessitent pas d'être usinés avec une grande précision, ce qui permet de réduire les coûts de fabrication.The present invention proceeds from the general inventive idea which consists in screwing a bottom not directly on the middle part of a watch case, but with the aid of an intermediate element screwed respectively on the bottom and the middle part by means of two threads having opposite steps. Thus, when the bottom is screwed in abutment on the middle part, the bottom can still be pivoted relative to the middle part of the watch in order to adjust its alignment for example with respect to the vertical axis 12 hours to 6 hours of said watch. This is made possible by the displacement of the intermediate element along the thread of the middle part, displacement allowed by the arrangement of the two threads in opposite steps. Thanks to these features, the present invention further provides a watch case whose middle and bottom do not need to be machined with high precision, which reduces manufacturing costs.

La boîte de montre selon l'invention est représentée en coupe et à l'état dissocié sur la figure 1. Désignée dans son ensemble par la référence numérique générale 1, la boîte 1 comporte une carrure 2 définissant un logement 4 fermé de façon classique par un verre (non représenté) et un fond 6 ainsi qu'un élément intermédiaire 8 destiné à être interposé entre le fond 6 et la carrure 2. La carrure 2 présente également un perçage 10 pour le passage d'une tige (non représentée) sur laquelle est fixée une couronne 12. Le fond 6 qui, dans l'exemple représenté, est circulaire, présente une portion filetée 14 dont le pas est orienté selon un premier sens tandis que la carrure 2 comprend une portion filetée 16 dont le pas est orienté selon un deuxième sens opposé à celui du fond 6. L'élément intermédiaire 8 présente une première portion filetée 18 destinée à coopérer avec la portion filetée 14 du fond 6 et une deuxième portion filetée 20 destinée à coopérer avec la portion filetée 16 de la carrure 2. L'élément intermédiaire 8 se présente dans le mode de réalisation représenté sous la forme d'une bague munie d'une ouverture intérieure circulaire 22. La surface extérieure de la bague 8 est étagée et comprend une portion cylindrique 24 ayant un premier diamètre D1 suivie d'une portion cylindrique 26 ayant un deuxième diamètre D2 inférieur au premier diamètre D1.The watch case according to the invention is shown in section and in the dissociated state on the figure 1 . Designated as a whole by the general numerical reference 1, the box 1 comprises a caseband 2 defining a housing 4 conventionally closed by a glass (not shown) and a bottom 6 and an intermediate element 8 intended to be interposed between the bottom 6 and the middle part 2. The middle part 2 also has a bore 10 for the passage of a rod (not shown) on which is fixed a ring 12. The bottom 6 which, in the example shown, is circular, has a threaded portion 14 whose pitch is oriented in a first direction while the middle part 2 comprises a threaded portion 16 whose pitch is oriented in a second direction opposite to that of the bottom 6. The intermediate element 8 has a first threaded portion 18 intended to cooperate with the threaded portion 14 of the bottom 6 and a second threaded portion 20 intended to cooperate with the threaded portion 16 of the middle part 2. The intermediate element 8 is in the embodiment shown in the form of a ring provided with a circular inner opening 22. The outer surface of the ring 8 is stepped and comprises a cylindrical portion 24 having a first diameter. D1 followed by a cylindrical portion 26 having a second diameter D2 less than the first diameter D1.

La première portion filetée 18 de la bague 8 est réalisée dans la paroi cylindrique de l'ouverture 22 de celle-ci tandis que la deuxième portion filetée 20 est réalisée sur la portion cylindrique 24 extérieure de grand diamètre de la bague 8.The first threaded portion 18 of the ring 8 is formed in the cylindrical wall of the opening 22 thereof while the second threaded portion 20 is formed on the outer cylindrical portion 24 of large diameter of the ring 8.

On notera également que la portion 26 de diamètre inférieur de la bague 8 comprend à sa surface extérieure une gorge annulaire 28 dans laquelle est disposé un anneau élastique 30 dont la fonction sera précisée ci-après.It will also be noted that the portion 26 of smaller diameter of the ring 8 comprises at its outer surface an annular groove 28 in which is disposed an elastic ring 30 whose function will be specified below.

A la figure 1 on voit également que la face 32 du fond 6 dirigée vers l'intérieur de la boîte 1 comprend une rainure annulaire 34 dont une paroi verticale comprend le filetage 14 destiné à coopérer avec le filetage 18 de la bague 8. La largeur de la rainure 34 est dimensionnée pour recevoir la portion 26 de diamètre inférieur de la bague 8 et comprimer l'anneau élastique 30 contre la paroi 36 de la rainure 34 opposée au filetage 14 lorsque la bague 8 est vissée sur le fond 6. On comprend donc que lorsque l'anneau élastique 30 est comprimé contre la paroi 36 de la rainure 34, les forces de frottement entre la bague 8 et le fond 6 augmentent et engendrent une augmentation du couple de friction entre ces deux éléments.To the figure 1 it is also seen that the face 32 of the bottom 6 facing the inside of the box 1 comprises an annular groove 34, a vertical wall comprises the thread 14 intended to cooperate with the thread 18 of the ring 8. The width of the groove 34 is dimensioned to receive the portion 26 of smaller diameter of the ring 8 and compress the elastic ring 30 against the wall 36 of the groove 34 opposite the thread 14 when the ring 8 is screwed on the bottom 6. It is therefore understood that when the elastic ring 30 is compressed against the wall 36 of the groove 34, the frictional forces between the ring 8 and the bottom 6 increase and cause an increase in the friction torque between these two elements.

La bague 8 peut être réalisée par exemple en acier. Quant à l'élément élastique de blocage 30, il peut être réalisé en un élastomère naturel ou synthétique, ou encore en un matériau thermoplastique dont le taux de rémanence après compression est bien adapté aux besoins de la présente invention.The ring 8 can be made for example of steel. As for the elastic locking element 30, it can be made of a natural or synthetic elastomer, or a thermoplastic material whose compression afterglow rate is well suited to the needs of the present invention.

De préférence, la hauteur de la portion 24 de diamètre supérieur de la bague 8 est inférieure à la hauteur de la portion 26 de diamètre inférieur de cette bague 8 et la profondeur de la rainure annulaire 34 du fond 6 est supérieure ou égale à la hauteur de la portion 26 de diamètre inférieur de la bague 8.Preferably, the height of the portion 24 of greater diameter of the ring 8 is smaller than the height of the portion 26 of smaller diameter of this ring 8 and the depth of the annular groove 34 of the bottom 6 is greater than or equal to the height of the portion 26 of lower diameter of the ring 8.

On notera qu'un joint torique 38 est classiquement inséré dans une gorge annulaire 40 pratiquée à la base de la carrure 2 pour garantir l'étanchéité entre le fond 6 et la carrure 2 et que la surface extérieure 42 du fond 6 tournée du côté du poignet du porteur de la montre 26 comprend des encoches 44 qui servent à l'introduction des tenons d'une clé de serrage (non représentée).Note that an O-ring 38 is conventionally inserted into an annular groove 40 formed at the base of the middle part 2 to ensure the seal between the bottom 6 and the middle part 2 and that the outer surface 42 of the bottom 6 turned on the side of the The wrist of the wearer of the watch 26 comprises notches 44 which serve to introduce the tenons of a wrench (not shown).

A la figure 6 on a représenté une variante de réalisation de la boîte de montre selon l'invention dans laquelle les éléments identiques à ceux décrits précédemment sont désignés par les mêmes références numériques. Cette variante de réalisation se distingue de la boite de montre décrite en liaison avec les figures 1 à 5 en ce que les moyens pour augmenter le couple de friction entre la bague 8 et le fond 6 sont formés par un manchon cylindrique 50 disposé sur la portion cylindrique D2 de plus faible diamètre de la bague 8, le diamètre extérieur du manchon 50 et le diamètre défini par la paroi intérieure 36 étant ajustés pour créer une friction lorsque la bague 8 est vissée sur le fond 6. Le manchon peut être typiquement réalisé en Asutane, commercialisé par la société Asulab SA, Marin, Suisse.To the figure 6 there is shown an alternative embodiment of the watch case according to the invention wherein the elements identical to those described above are designated by the same reference numerals. This embodiment variant is distinguished from the watch case described in connection with the Figures 1 to 5 in that the means for increasing the frictional torque between the ring 8 and the bottom 6 are formed by a cylindrical sleeve 50 arranged on the cylindrical portion D2 of smaller diameter of the ring 8, the outside diameter of the sleeve 50 and the diameter defined by the inner wall 36 being adjusted to create friction when the ring 8 is screwed on the bottom 6. The sleeve can be typically made of Asutane, sold by Asulab SA, Marin, Switzerland.

A la figure 7 on a représenté une autre variante de réalisation de la boîte de montre selon l'invention dans laquelle les éléments identiques à ceux décrits précédemment sont désignés par les mêmes références numériques. Cette variante de réalisation se distingue de la boite de montre décrite en liaison avec les figures 1 à 5 en ce que les portions filetées 18 et 20 de la bague 8 sont ménagées toutes les deux sur le pourtour extérieur de la bague et en particulier sur le même diamètre. En outre on notera que la portion filetée 14 du fond est ménagée dans la paroi opposée de la rainure, et que les moyens pour augmenter le couple de friction entre la bague 8 et le fond 6 sont formés par un manchon 50 disposé dans la rainure 34 entre la paroi de la rainure opposée à la portion filetée 14 et la paroi cylindrique intérieure de la bague 8.To the figure 7 another embodiment of the watch case according to the invention has been shown in which the elements identical to those described above are designated by the same reference numerals. This embodiment variant is distinguished from the watch case described in connection with the Figures 1 to 5 in that the threaded portions 18 and 20 of the ring 8 are arranged both on the outer periphery of the ring and in particular on the same diameter. In addition it will be noted that the threaded portion 14 of the bottom is formed in the opposite wall of the groove, and that the means for increasing the frictional torque between the ring 8 and the bottom 6 are formed by a sleeve 50 disposed in the groove 34 between the wall of the groove opposite the threaded portion 14 and the inner cylindrical wall of the ring 8.

On va maintenant décrire en liaison avec les figures 2 à 5 le procédé d'orientation du fond 6 de la boîte 1 sur la carrure 2.We will now describe in connection with Figures 2 to 5 the process of orientation of the bottom 6 of the box 1 on the middle part 2.

Pour ce faire, on assemble dans une première étape la bague 8 sur le fond 6 par vissage de ces éléments l'un sur l'autre dans un premier sens de rotation jusqu'à ce que la portion 24 de plus grand diamètre vienne en butée contre la face 32 du fond 6. Ce faisant, le joint 28 est alors comprimé contre la paroi 36 de la rainure 34 et engendre un couple de friction qui est plus important que le couple de friction entre la bague 8 et la carrure 2 lorsque la bague 8 sera ultérieurement vissée sur la carrure 2.To do this, the ring 8 is assembled in a first step on the bottom 6 by screwing these elements one over the other in a first direction of rotation until the portion 24 of greater diameter comes into abutment. against the face 32 of the bottom 6. In doing so, the seal 28 is then compressed against the wall 36 of the groove 34 and generates a friction torque which is greater than the friction torque between the ring 8 and the middle part 2 when the ring 8 will be subsequently screwed on the middle part 2.

Une fois l'ensemble formé par le fond 6 et la bague 8 assemblé par vissage, cet ensemble est ensuite vissé par l'introduction des tenons d'une clé de serrage dans les encoches 44 sur la carrure 2 par le filetage 20 qui présente un pas dans un sens opposé à celui du filetage 18 et qui vient en prise avec le filetage 16 de ladite carrure 2. Le vissage de l'ensemble fond 6-bague 8 s'interrompt lorsque le fond 6 vient en butée sur la surface inférieure de la carrure 2.Once the assembly formed by the bottom 6 and the ring 8 assembled by screwing, this assembly is then screwed by the introduction of the tenons of a wrench into the notches 44 on the middle part 2 by the thread 20 which has a not in a direction opposite to that of the thread 18 and which engages the thread 16 of said middle part 2. The screwing of the bottom 6-ring 8 assembly stops when the bottom 6 abuts on the lower surface of the middle part 2.

Une fois vissé, on voit à la figure 3A que le fond 6 sur lequel un motif 46 est reporté (en l'espèce, il s'agit de la lettre grecque majuscule oméga) est totalement désaligné par rapport à l'axe vertical 12h-6h de la montre. Le problème consiste donc à redresser ce motif 46 afin qu'il soit convenablement aligné et que l'aspect esthétique de la montre s'en trouve amélioré. A cet effet, une fois le fond 6 vissé en butée sur l'élément intermédiaire 8, on continue de visser ledit fond 6 toujours à l'aide de la clé de serrage. A ce moment, comme le fond 6 bute contre la carrure 2 et comme la bague 8 est vissée sur le fond 6 au moyen du filetage 18 dont le pas est de sens opposé à celui 20 par lequel elle est vissée sur la carrure 2, le fond 6 peut être tourné pour l'orienter de la manière désirée, en provoquant un déplacement vertical de la bague 8 le long du filetage 16 de la carrure 2 (figure 4A).Once screwed, we see at the figure 3A that the background 6 on which a pattern 46 is reported (in this case, it is the Greek capital letter omega) is totally misaligned with respect to the vertical axis 12h-6h of the watch. The problem is therefore to straighten the pattern 46 so that it is properly aligned and the aesthetic appearance of the watch is improved. For this purpose, once the bottom 6 screwed in abutment on the intermediate element 8, one continues to screw said bottom 6 always with the help of the wrench. At this time, as the bottom 6 abuts against the middle part 2 and as the ring 8 is screwed to the bottom 6 by means of the thread 18 whose pitch is opposite direction to that 20 by which it is screwed on the middle part 2, the bottom 6 can be rotated to orient it in the desired manner, causing a vertical displacement of the ring 8 along the thread 16 of the middle part 2 ( Figure 4A ).

Le problème se pose maintenant de savoir comment dévisser le fond 6 lorsque cela est nécessaire. A cet effet, on continue d'utiliser la clé de serrage pour dévisser cet ensemble jusque tant que l'ensemble fond 6-bague 8 se désolidarise de la carrure 2, la friction entre le fond 6 et la bague 8 maintenant l'ensemble solidaire. Après quoi, en utilisant la même clé de serrage ou un autre outil adapté, on dévisse la bague 8 du fond 6. A cet effet, la bague 8 comprend des encoches 48 pour la réception des tenons de l'outil (voir figure 5). Alternativement on peut continuer de visser le fond 6 pour que la bague 8 se déplace vers l'intérieur de la carrure le long de la portion filetée 16 jusqu'à ce que la bague se désolidarise du fond 6.The problem now arises of how to unscrew the bottom 6 when necessary. For this purpose, we continue to use the wrench to unscrew this set until the 6-ring bottom assembly 8 disengages from the middle part 2, the friction between the bottom 6 and the ring 8 now the whole solidarity . After which, using the same tightening wrench or another suitable tool, the ring 8 of the bottom 6 is unscrewed. For this purpose, the ring 8 comprises notches 48 for receiving the tenons of the tool (see FIG. figure 5 ). Alternatively one can continue to screw the bottom 6 so that the ring 8 moves inwardly of the middle part along the threaded portion 16 until the ring disengages the bottom 6.

Le procédé décrit ci-dessus s'applique mutatis mutandis aux modes de réalisation de la boite de montre selon l'invention représentés aux figures 6 et 7.The method described above applies mutatis mutandis to the embodiments of the watch case according to the invention shown in FIGS. Figures 6 and 7 .

Comme on l'aura compris de ce qui précède, la présente invention peut s'appliquer à tout type de pièce d'horlogerie présentant un fond fixé sur la carrure par vissage et ne nécessite, pour pouvoir être mise en oeuvre, que des modifications mineures qui pour l'essentiel ont trait à la forme à donner à la carrure 2 au niveau de sa partie inférieure où se fait la jonction avec le fond 6.As will be understood from the foregoing, the present invention can be applied to any type of timepiece having a bottom fixed to the middle part by screwing and requires, to be able to be implemented, only minor modifications. which essentially relate to the shape to give the middle part 2 at its lower part where the junction with the bottom 6 is made.

Il va de soi que l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées sans sortir du cadre de l'invention définie par les revendications annexées. En particulier, il pourrait être envisagé que la bague se visse sur le fond par un filetage prévu sur la surface extérieure de sa portion cylindrique de plus grand diamètre et qu'elle se visse sur la carrure par un filetage prévu sur la surface intérieure de sa portion cylindrique de plus petit diamètre.It goes without saying that the invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged without departing from the scope of the invention defined by the appended claims. In particular, it could be envisaged that the ring is screwed on the bottom by a thread provided on the outer surface of its cylindrical portion of larger diameter and that it is screwed on the middle part by a thread provided on the inner surface of its cylindrical portion of smaller diameter.
