Description

La présente invention concerne une boîte de montre avec un fond séparable de la carrure. Plus particulièrement, cette invention concerne une boîte de montre munie d'un fond formant avec les deux attaches au bracelet une seule et même pièce.The present invention relates to a watch case with a bottom separable from the middle part. More particularly, this invention relates to a watch case provided with a bottom forming with the two attachments to the bracelet one and the same piece.

Il est connu du document CH 662 698 une boîte de montre comportant un fond séparable de la carrure, ce fond formant avec les deux attaches au bracelet une seule et même pièce. Dans ce document, l'attache au bracelet comprend une base aux extrémités de laquelle se trouvent deux cornes servant à la fixation de la barrette de fixation du bracelet, la base de cette attache étant reliée au fond par un pont. Le pont de cette attache a la forme d'un parallèlipipède rectangle et la base de l'attache de forme allongée et orientée transversalement au pont présente une surface externe située dans le même plan que la surface externe dudit fond de cette boîte de montre, la section transversale de la base ayant la forme d'un triangle dont l'angle externe est tronqué.Document CH 662 698 discloses a watch case comprising a bottom separable from the middle part, this bottom forming with the two attachments to the bracelet one and the same piece. In this document, the strap attachment comprises a base at the ends of which there are two horns used for fixing the strap fixing bar, the base of this clip being connected to the bottom by a bridge. The bridge of this fastener has the shape of a rectangular parallelipiped and the base of the fastener of elongated shape and oriented transversely to the bridge has an external surface located in the same plane as the external surface of said back of this watch case, the cross section of the base having the shape of a triangle whose external angle is truncated.

Chacune des cornes a la forme d'un parallèlipipède rectangle situé sur une des extrémités de la base de l'attache. Etant donné que la section de la base est de forme triangulaire tronquée, la corne a une orientation générale dont la direction est légèrement décalée angulairement par rapport à la direction perpendiculaire au plan défini par la surface externe du fond de la boîte.Each of the horns has the shape of a rectangular parallelepiped located on one of the ends of the base of the clip. Since the base section is of truncated triangular shape, the horn has a general orientation whose direction is slightly angularly offset from the direction perpendicular to the plane defined by the outer surface of the bottom of the box.

L'attache décrite dans ce document présente l'inconvénient suivant : la section triangulaire tronquée de la base associée à deux cornes, ayant chacune la forme d'un parallèlipipède rectangle, engendre une réalisation en plusieurs étapes nécessitant au moins une étape d'usinage. Ce document décrit donc une boîte de montre présentant des attaches aux formes géométriques simples, mais nécessitant une réalisation relativement onéreuse.The attachment described in this document has the following drawback: the truncated triangular section of the base associated with two horns, each having the shape of a rectangular parallelipiped, generates an embodiment in several steps requiring at least one machining step. This document therefore describes a watch case having fasteners with simple geometric shapes, but requiring a relatively expensive production.

Un premier but de l'invention est de fournir une boîte de montre comprenant un fond séparable de la carrure et formant avec deux attaches pour fixer un bracelet une seule et même pièce, chaque attache comportant deux cornes dont l'orientation générale présente un décalage angulaire relativement au plan médian trois heures - neuf heures de ladite boîte de montre, pour un coût de fabrication peu onéreux.A first object of the invention is to provide a watch case comprising a bottom separable from the middle part and forming with two fasteners to fix a bracelet a single piece, each fastener comprising two horns whose general orientation is an angular offset relative to the median plane three hours - nine hours of said watch case, for an inexpensive manufacturing cost.

Un autre but de l'invention est de fournir une telle boîte de montre avec des cornes ayant une forme adaptée pour définir un trou borgne destiné à une extrémité d'un moyen de fixation dudit bracelet.Another object of the invention is to provide such a watch case with horns having a shape adapted to define a blind hole intended for one end of a means of fixing said bracelet.

La présente invention a donc pour objet une boîte de montre comprenant une carrure, un fond définissant un plan général et deux attaches pour fixer un bracelet, ce fond formant avec les deux attaches une seule et même pièce, chacune desdites attaches présentant, relativement à une projection dans ledit plan général dudit fond, sensiblement la forme générale d'un T dont la branche médiane forme un pont de raccordement de l'attache audit fond et dont la branche transversale forme une base pour deux cornes s'étendant respectivement à partir des deux extrémités de cette base dans un seul et même sens selon un axe d'orientation générale présentant un décalage angulaire relativement au plan médian trois heures - neuf heures de ladite boîte de montre, les deux cornes appartenant à une même attache présentant sensiblement un plan de symétrie comprenant ledit axe d'orientation générale de chacune de ces deux cornes, ladite boîte de montre étant caractérisée en ce que ladite base de chaque attache est sensiblement symétrique relativement audit plan de symétrie des deux cornes s'étendant à partir de cette base.The present invention therefore relates to a watch case comprising a middle part, a base defining a general plan and two fasteners for attaching a bracelet, this bottom forming with the two fasteners a single piece, each of said fasteners having, relative to a projection in said general plane of said bottom, substantially the general shape of a T, the middle branch of which forms a bridge connecting the attachment to said bottom and the transverse branch of which forms a base for two horns extending respectively from the two ends of this base in one and the same direction along an axis of general orientation having an angular offset relative to the median plane three hours - nine hours of said watch case, the two horns belonging to the same attachment having substantially a plane of symmetry comprising said general orientation axis of each of these two horns, said watch case being characterized by that said base of each fastener is substantially symmetrical relative to said plane of symmetry of the two horns extending from this base.

Il résulte de ces caractéristiques qu'il est aisé de fabriquer la pièce formant le fond et les deux attaches pour fixer le bracelet uniquement par étampage et par pliage, ce qui permet de fabriquer ladite pièce de manière industrielle à un coût peu onéreux. Par étampage, on comprend le fait d'écraser et/ou de repousser diverses parties d'une pièce de métal.It follows from these characteristics that it is easy to manufacture the part forming the bottom and the two fasteners for fixing the bracelet only by stamping and by folding, which makes it possible to manufacture said part industrially at an inexpensive cost. By stamping, it is understood to crush and / or push back various parts of a piece of metal.

Dans un mode de réalisation préféré de l'invention, ledit pont reliant ladite base audit fond est incurvé du côté de la surface externe de ce fond, le profil formé par les surfaces externes dudit fond, dudit pont et de ladite base dans le plan médian six heures-douze heures de ladite boîte de montre définissant une ligne continue et lisse.In a preferred embodiment of the invention, said bridge connecting said base to said bottom is curved on the side of the external surface of this bottom, the profile formed by the external surfaces of said bottom, of said bridge and of said base in the median plane six to twelve o'clock in the said watch case defining a continuous and smooth line.

Selon d'autres caractéristiques de ce mode de réalisation préféré, lesdites cornes ont une épaisseur supérieure à l'épaisseur de la région périphérique dudit fond et chacune de ces cornes présente un trou borgne ayant une unique ouverture située dans la surface interne de ladite corne et destiné à recevoir une extrémité d'un moyen servant à fixer ledit bracelet à ladite boîte de montre.According to other characteristics of this preferred embodiment, said horns have a thickness greater than the thickness of the peripheral region of said bottom and each of these horns has a blind hole having a single opening located in the internal surface of said horn and intended to receive one end of a means serving to fix said bracelet to said watch case.

Selon une variante de ce mode de réalisation, lesdites cornes ont sensiblement la forme d'un demi-ellipsoide de révolution.According to a variant of this embodiment, said horns have substantially the shape of a semi-ellipsoid of revolution.

Il résulte de ce mode de réalisation préféré une boîte de montre dont l'épaisseur de la région périphérique du fond est indépendante et sensiblement inférieure à l'épaisseur des cornes, ce qui présente un double avantage.The result of this preferred embodiment is a watch case whose thickness of the peripheral region of the bottom is independent and substantially less than the thickness of the horns, which has a double advantage.

Premièrement, l'épaisseur nécessaire à la corne pour que celle-ci puisse aisément avoir un trou borgne, destiné à recevoir une extrémité d'un moyen de fixation du bracelet et ayant une seule et unique ouverture dans la surface interne de cette corne, n'engendre pas de répercussions sur l'épaisseur de la région périphérique du fond, ce qui permet à cette dernière d'être suffisamment petite pour donner à la boîte de montre une épaisseur minimale sans pour autant nécessiter un trou pour l'extrémité de la barrette qui traverse entièrement la corne.First, the thickness necessary for the horn so that it can easily have a blind hole, intended to receive one end of a means of fixing the bracelet and having a single opening in the internal surface of this horn, n '' does not affect the thickness of the peripheral region of the back, which allows the latter to be small enough to give the watch case a minimum thickness without requiring a hole for the end of the bar which crosses the horn entirely.

On notera qu'il est avantageux pour la réalisation de la boîte de montre, spécialement si celle-ci est étanche, que la région périphérique du fond ait une épaisseur relativement petite, de telle manière que ce fond séparable de la carrure reste en-dessous du niveau du trou de la tige de mise à l'heure.Note that it is advantageous for the production of the watch case, especially if it is waterproof, that the peripheral region of the back has a relatively small thickness, so that this back separable from the middle stays below of the hole in the time setting rod.

Deuxièmement, l'épaisseur de la corne étant indépendante de l'épaisseur de la région périphérique du fond, la corne peut avoir une épaisseur suffisamment grande pour présenter une forme harmonieuse qui souligne le caractère esthétique de cette boîte de montre, la corne ayant par exemple une forme d'un demi-ellipsoide de révolution ou d'un demi-oeuf ou toute autre forme artistique évoquant le travail artisanal d'un orfèvre.Secondly, the thickness of the horn being independent of the thickness of the peripheral region of the back, the horn can have a thickness large enough to present a harmonious shape which underlines the aesthetic character of this watch case, the horn having for example a form of a half-ellipsoid of revolution or a half-egg or any other artistic form evoking the artisanal work of a goldsmith.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux à la lecture de la description détaillée qui suit, faite en référence aux dessins annexés qui sont donnés uniquement à titre d'exemple et dans lesquels:

  • la figure 5 est une vue éclatée de la boîte de montre selon l'invention lorsque celle-ci est regardée de côté selon une direction correspondant à l'axe 6 heures - 12 heures de cette boîte de montre.
Other characteristics and advantages of the invention will appear better on reading the detailed description which follows, given with reference to the appended drawings which are given solely by way of example and in which:
  • Figure 1 shows a plan view of the watch case according to the invention;
  • Figures 2 and 3 are respectively sectional views along lines II-II and III-III of Figure 1;

  • Figure 5 is an exploded view of the watch case according to the invention when it is viewed from the side in a direction corresponding to the 6 o'clock - 12 o'clock axis of this watch case.

En se référant aux figures 1 à 5, on décrira ci-après un mode de réalisation préféré d'une boîte de montre selon l'invention.Referring to Figures 1 to 5, a preferred embodiment of a watch case according to the invention will be described below.

La boîte de montre 1 comprend une carrure-lunette 2 et une pièce 4 formant le fond 6 avec les deux attaches 8 et 9 servant à fixer le bracelet. Cette boîte de montre comprend encore un verre 10 placé dans un joint d'étanchéité 11, lequel fait aussi office de réhaut entre le verre 10 et le cadran 12 de cette montre.The watch case 1 comprises a middle-bezel 2 and a part 4 forming the base 6 with the two fasteners 8 and 9 used to fix the bracelet. This watch case also includes a glass 10 placed in a seal 11, which also acts as a flange between the glass 10 and the dial 12 of this watch.

Le mouvement 14 de cette montre est logé dans un cercle d'encageage 16 ayant en section radiale un prolongement qui vient s'appuyer contre la surface interne 18 du fond 6. Un joint d'étanchéité 20 est prévu à l'intérieur d'un logement formé par la carrure-lunette 2, le fond 6 et le cercle d'encageage 16.The movement 14 of this watch is housed in a casing circle 16 having in radial section an extension which comes to bear against the internal surface 18 of the base 6. A seal 20 is provided inside a housing formed by the middle part-bezel 2, the bottom 6 and the casing ring 16.

La pièce 4 formant le fond avec les deux attaches servant à fixer le bracelet comprend essentiellement quatre régions ayant une épaisseur distincte. La région la plus mince, d'une épaisseur 22, forme la région centrale 21 du fond 6, cette région centrale 21 comprenant la région de superposition avec le mouvement 14 de la montre. La région périphérique 23 du fond 6 forme une deuxième région présentant une épaisseur 24 spécifique, le bord extérieur du fond étant arrondi. La surface interne de cette région périphérique 23 constitue la surface de contact avec la carrure-lunette 2 de cette boîte de montre. Des trous 26 sont prévus dans cette région périphérique 23, ces trous étant destinés au passage des vis de fixation 28 servant à maintenir ensemble la carrure-lunette 2 et la pièce 4 formant le fond avec les deux attaches pour fixer le bracelet.The part 4 forming the bottom with the two fasteners used to fix the bracelet essentially comprises four regions having a distinct thickness. The thinnest region, of a thickness 22, forms the central region 21 of the back 6, this central region 21 comprising the region of superposition with the movement 14 of the watch. The peripheral region 23 of the bottom 6 forms a second region having a specific thickness 24, the outer edge of the bottom being rounded. The internal surface of this peripheral region 23 constitutes the contact surface with the middle-bezel 2 of this watch case. Holes 26 are provided in this peripheral region 23, these holes being intended for the passage of the fixing screws 28 serving to hold together the middle part-bezel 2 and the part 4 forming the base with the two fasteners for fixing the bracelet.

Ensuite, la base 30 de chacune des deux attaches 8 et 9 forme une troisième région de la pièce 4 ayant une épaisseur spécifique, à savoir une épaisseur 31 légèrement supérieure à l'épaisseur 24 de la région périphérique 23 de cette pièce 4. Finalement, cette pièce 4 comprend encore quatre cornes 34a à 34d, chacune de ces cornes définissant une largeur 35 supérieure à l'épaisseur 24 de la région périphérique 23 du fond 6 et supérieure ou égale à l'épaisseur 31 de la base 30 de l'attache 8, respectivement 9. On notera cependant que l'épaisseur 31 de la base 30 peut être, dans une autre variante de ce mode de réalisation, plus petite ou égale à l'épaisseur 24 de la région périphérique 23.Then, the base 30 of each of the two fasteners 8 and 9 forms a third region of the part 4 having a specific thickness, namely a thickness 31 slightly greater than the thickness 24 of the peripheral region 23 of this part 4. Finally, this part 4 further comprises four horns 34a to 34d, each of these horns defining a width 35 greater than the thickness 24 of the peripheral region 23 of the bottom 6 and greater than or equal to the thickness 31 of the base 30 of the fastener 8, respectively 9. It will however be noted that the thickness 31 of the base 30 may be, in another variant of this embodiment, less than or equal to the thickness 24 of the peripheral region 23.

Outre la base 30 et les cornes 34a et 34b, respectivement 34c et 34d, chacune des deux attaches 8 et 9 comprend encore un pont 36 reliant la région périphérique 23 du fond 6 avec la base 30 de l'attache 8, respectivement 9. Ce pont 36 présente une épaisseur diminuant progressivement entre l'épaisseur 24 de la région périphérique 23 et l'épaisseur 31 de la base 30 de l'attache 8, respectivement 9. Ce pont 36 forme un étranglement entre le fond 6 et la base 30 de l'attache 8, respectivement 9. Ainsi, la base 30 a la forme d'une barre orientée transversalement a la direction donnée par les deux ponts 36 de la pièce 4 de cette boîte de montre 1. On notera que dans la vue en plan de la figure 4, chaque attache présente la forme générale d'un T.In addition to the base 30 and the horns 34a and 34b, respectively 34c and 34d, each of the two fasteners 8 and 9 also comprises a bridge 36 connecting the peripheral region 23 of the bottom 6 with the base 30 of the fastener 8, respectively 9. This bridge 36 has a thickness which decreases progressively between the thickness 24 of the peripheral region 23 and the thickness 31 of the base 30 of the clip 8, respectively 9. This bridge 36 forms a constriction between the bottom 6 and the base 30 of the fastener 8, respectively 9. Thus, the base 30 has the form of a bar oriented transversely to the direction given by the two bridges 36 of the part 4 of this watch case 1. It will be noted that in the plan view in Figure 4, each fastener has the general shape of a T.

Afin de repérer dans l'espace la boîte de montre 1, on nomme haut ou dessus ou encore partie supérieure de la montre la région située du côté du verre 10 de montre et bas ou dessous ou encore partie inférieure de la boîte de montre la région définie par le fond 6 de la boîte de montre. La région centrale 21 du fond 6 de la boîte de montre définit un plan général 38. Ce plan général 38 est ici parallèle au plan général de la boîte de montre. La base 30 de l'attache 8, respectivement 9 définit un plan général 40, respectivement 41. Ce plan général 40, respectivement 41 est décalé angulairement d'un angle α par rapport au plan général 38 du fond de la boîte de montre. Par plan général d'une pièce, on comprend le plan dans lequel s'étend sensiblement cette pièce. On notera ici que les références entre parenthèses sur la figure 2 mentionnent les éléments qui apparaissent lorsque l'on fait subir à la boîte de montre de la figure 1 une rotation de 180° dans le plan de représentation de cette figure 1.In order to locate the watch case 1 in space, the region located on the side of the watch glass 10 and the bottom or below or the lower part of the watch case is called the top or above or even upper part of the watch. defined by the bottom 6 of the watch case. The central region 21 of the bottom 6 of the watch case defines a general plane 38. This general plane 38 is here parallel to the general plane of the watch case. The base 30 of the fastener 8, respectively 9 defines a general plane 40, respectively 41. This general plane 40, respectively 41 is angularly offset by an angle α relative to the general plane 38 of the bottom of the watch case. By general plan of a part, we understand the plane in which this part extends substantially. It will be noted here that the references in parentheses in FIG. 2 mention the elements which appear when the watch case is subjected to of figure 1 a rotation of 180 ° in the plane of representation of this figure 1.

Les deux cornes 34a et 34b, respectivement 34c et 34d, s'étendant dans un seul et même sens à partir des deux extrémités de la base 30 de chacune des deux attaches 8 et 9, sont orientées vers le haut de la montre selon un axe d'orientation générale 44, respectivement 45 sensiblement perpendiculaire au plan général 40, respectivement 41 de la base 30 de l'attache au bracelet 8, respectivement 9. Ainsi, les cornes des deux attaches au bracelet 8 et 9 sont orientées selon une direction décalée angulairement d'un angle α par rapport au plan médian trois heures - neuf heures de la boîte de montre 1. Le décalage angulaire α des cornes 34a à 34d permet de dégager ces cornes du bord de la carrure-lunette 2 en leur donnant une orientation appropriée au contour du poignet d'une personne susceptible de porter cette montre.The two horns 34a and 34b, respectively 34c and 34d, extending in one and the same direction from the two ends of the base 30 of each of the two fasteners 8 and 9, are oriented towards the top of the watch along an axis of general orientation 44, respectively 45 substantially perpendicular to the general plane 40, respectively 41 of the base 30 of the strap fastener 8, respectively 9. Thus, the horns of the two strap fasteners 8 and 9 are oriented in an offset direction angularly at an angle α with respect to the median plane three hours - nine hours from the watch case 1. The angular offset α of the horns 34a to 34d allows these horns to be released from the edge of the middle-bezel 2 by giving them an orientation suitable for the wrist area of a person likely to wear this watch.

De plus, les deux cornes et la base d'une même attache présentent sensiblement un plan de symétrie commun, ce plan de symétrie comprenant les deux axes 44, respectivement 45 d'orientation générale des deux cornes de cette attache.In addition, the two horns and the base of the same attachment have substantially a common plane of symmetry, this plane of symmetry comprising the two axes 44, 45 respectively of general orientation of the two horns of this attachment.

Grâce à la structure de la pièce 4, formant le fond 6 avec les deux attaches 8 et 9, et en particulier de la dernière caractéristique mentionnée ci-avant, il est aisément possible de fabriquer cette pièce 4 par étampage et par pliage. Par exemple, on obtient par étampage une pièce avec les cornes orientées sensiblement dans le prolongement de la base respective. Puis par pliage, ces cornes sont orientées selon une direction sensiblement perpendiculaire au plan général de ladite base respective.Thanks to the structure of the part 4, forming the bottom 6 with the two fasteners 8 and 9, and in particular of the last characteristic mentioned above, it is easily possible to manufacture this part 4 by stamping and by folding. For example, a piece is obtained by stamping with the horns oriented substantially in the extension of the respective base. Then by folding, these horns are oriented in a direction substantially perpendicular to the general plane of said respective base.

Le pont 36 reliant la région périphérique 23 du fond 6 à la base 30 de l'attache au bracelet 8, respectivement 9 est incurvé de manière sensiblement continue en direction du dessous de la boîte de montre, c'est-à-dire du côté de la surface externe 48 du fond 6. Le profil formé par les surfaces externes 48, 58 et 50 du fond 6, du pont 36 et de la base 30 dans le plan médian six heures - douze heures II-II définit une ligne continue et lisse. Par lisse, on indique que la ligne ne présente ni angle, ni décrochement. Ainsi, lorsque la boîte de montre 1 est posée sur son fond 6, la pièce 4 formant le fond 6 avec les deux attaches au bracelet 8 et 9 présente un profil convexe dans la région des attaches 8 et 9.The bridge 36 connecting the peripheral region 23 of the bottom 6 to the base 30 of the strap fastener 8, respectively 9 is curved in a substantially continuous direction towards the underside of the watch case, that is to say on the side of the external surface 48 of the base 6. The profile formed by the external surfaces 48, 58 and 50 of the base 6, of the bridge 36 and of the base 30 in the median plane six o'clock - twelve o'clock II-II defines a continuous line and smooth. By stringer, it indicates that the line has no angle or offset. Thus, when the watch case 1 is placed on its bottom 6, the part 4 forming the back 6 with the two strap attachments 8 and 9 has a convex profile in the region of the attachments 8 and 9.

On notera que dans un autre mode de réalisation de l'invention, les deux cornes situées aux extrémités de la base de chacune des deux attaches sont orientées sensiblement vers le bas de la boîte de montre, le pont reliant la région périphérique du fond à la base de l'attache au bracelet étant alors incurvé en direction du dessus de la boîte de montre, c'est-à-dire du côté du verre de montre. Dans ce dernier mode de réalisation, la surface interne et la surface externe de la base de l'attache au bracelet sont inversées par rapport au mode de réalisation représenté dans les figures 1 à 5.It will be noted that in another embodiment of the invention, the two horns situated at the ends of the base of each of the two fasteners are oriented substantially towards the bottom of the watch case, the bridge connecting the peripheral region of the back to the base of the strap attachment then being curved towards the top of the watch case, that is to say on the side of the watch glass. In this latter embodiment, the internal surface and the external surface of the base of the strap attachment are reversed with respect to the embodiment represented in FIGS. 1 to 5.

La base 30 de chacune des deux attaches 8 et 9 présente une surface externe 50 et une surface interne 52 située du côté du haut de la boîte de montre 1. De même, chacune des cornes 34a à 34d présente une surface externe 54 et surface interne 56. Le pont 36 de l'attache 8, respectivement 9 possède lui aussi une surface externe 58 et une surface interne 60 située du côté de la carrure-lunette 2. Les surfaces internes 52 de la base 30 et 56 des cornes 34a et 34b, respectivement 34c et 34d définissent un volume à l'intérieur duquel prend place une barrette de fixation du bracelet (non représentée) dont les extrémités sont insérées à l'intérieur de cavités 64 prévue dans chacune des cornes 34a à 34d. Ces cavités 64 présentent une seule ouverture située dans la surface interne 56 des cornes; elles forment donc des trous borgnes et s'ouvrent vers l'intérieur de l'attache.The base 30 of each of the two fasteners 8 and 9 has an external surface 50 and an internal surface 52 located on the top side of the watch case 1. Similarly, each of the horns 34a to 34d has an external surface 54 and internal surface 56. The bridge 36 of the fastener 8, respectively 9 also has an external surface 58 and an internal surface 60 located on the side of the middle part-bezel 2. The internal surfaces 52 of the base 30 and 56 of the horns 34a and 34b , respectively 34c and 34d define a volume inside which takes place a strap for fixing the strap (not shown), the ends of which are inserted inside cavities 64 provided in each of the horns 34a to 34d. These cavities 64 have a single opening located in the internal surface 56 of the horns; they therefore form blind holes and open towards the inside of the fastener.

On remarquera que la région centrale 21 du fond 6 de la boîte de montre forme un évidement dans la pièce 4 comprenant ce fond 6, les bords de cet évidement étant défini par la région périphérique 23 du fond 6. D'un autre côté, le fond 6 est situé partiellement à l'intérieur d'un évidement 68 prévu dans le fond de la carrure-lunette 2. On notera que cet évidement 68 reste en-dessous du niveau inférieur du trou 69 prévu pour la tige de mise à l'heure, laissant ainsi une épaisseur de matière 70 appartenant à la carrure-lunette 2 entre la région périphérique 23 du fond et ce trou 69. On notera encore que dans la figure 3, la tige de mise à l'heure et la couronne n'ont pas été représentées.It will be noted that the central region 21 of the bottom 6 of the watch case forms a recess in the part 4 comprising this bottom 6, the edges of this recess being defined by the peripheral region 23 of the bottom 6. On the other hand, the bottom 6 is located partially inside a recess 68 provided in the bottom of the middle-bezel 2. It will be noted that this recess 68 remains below the lower level of the hole 69 provided for the setting rod. hour, thus leaving a thickness of material 70 belonging to the middle part-bezel 2 between the peripheral region 23 of the base and this hole 69. It will also be noted that in FIG. 3, the time-setting rod and the crown n ' have not been represented.

Afin de donner un aspect monocoque à la boîte de montre, tout en en donnant à la carrure une forme de coupe évasée qui souligne le caractère très plat de la montre, le diamètre du fond 6 est inférieur au diamètre du verre 10 de la boîte de montre 1.In order to give a monocoque appearance to the watch case, while giving the middle a flared cup shape which emphasizes the very flat nature of the watch, the diameter of the back 6 is less than the diameter of the glass 10 of the watch case. shows 1.

Etant donné que le pont 36 relie de manière continue et sans décrochement la surface interne de la région périphérique 23 du fond 6 avec la surface interne 52 de la base 30, ainsi que la surface externe 48 du fond 6 avec la surface externe 50 de la base 30, une encoche 72 est nécessaire sur le bord inférieur de la carrure-lunette 2 définissant l'évidement 68.Since the bridge 36 continuously and without detachment connects the internal surface of the peripheral region 23 of the base 6 with the internal surface 52 of the base 30, as well as the external surface 48 of the base 6 with the external surface 50 of the base 30, a notch 72 is required on the lower edge of the middle part-bezel 2 defining the recess 68.

Cette encoche 72 a sensiblement une profondeur correspondant à la profondeur de l'évidement 68 opéré dans le fond de la carrure-lunette 2.This notch 72 has a substantially depth corresponding to the depth of the recess 68 operated in the bottom of the middle part-bezel 2.

Pour donner à la boîte de montre des formes harmonieuses et un aspect élégant, les surfaces externes de la région périphérique du fond 6, du pont 36 et de la base 30 sont partiellement arrondies. Les cornes 34a à 34d présentent sensiblement la forme d'un demi-ellipsoide de révolution, la surface plane définissant la surface interne 56, alors que la surface bombée définit la surface externe 54 de ces cornes. Dans une variante de ce mode préféré de réalisation de l'invention, d'autres formes peuvent être prévues, par exemple la forme d'un demi-oeuf. Cependant, chacune de ces formes doit avoir une épaisseur suffisante dans la région de la cavité 64 servant à recevoir l'extrémité de la barrette de fixation du bracelet.To give the watch case harmonious shapes and an elegant appearance, the external surfaces of the peripheral region of the back 6, the bridge 36 and the base 30 are partially rounded. The horns 34a to 34d have substantially the shape of a semi-ellipsoid of revolution, the planar surface defining the internal surface 56, while the convex surface defines the external surface 54 of these horns. In a variant of this preferred embodiment of the invention, other shapes can be provided, for example the shape of a half-egg. However, each of these forms must have a sufficient thickness in the region of the cavity 64 used to receive the end of the strap fixing strap.

On notera finalement qu'une boîte de montre selon l'invention peut avoir une lunette formée par une pièce distincte de la pièce formant la carrure.Finally, it should be noted that a watch case according to the invention may have a bezel formed by a part distinct from the part forming the middle part.
