Description

La présente invention concerne les boîtes de montre qui compren­nent une carrure faite en une matière minérale naturelle et venue de fabrication en une pièce avec un cadran.The present invention relates to watch cases which include a middle part made of a natural mineral material and produced in one piece with a dial.

Ce type de boîte présente un aspect esthétique particulièrement attractif. Toutefois, à cause de la fragilité des matières minérales naturelles, il est hors de question de fixer des marques ou des index par rivetage, chassage ou soudage. Par ailleurs, l'impression de signes n'a jusqu'ici pas donné de résultat satisfaisant.This type of box has a particularly attractive aesthetic appearance. However, because of the fragility of natural mineral materials, it is out of the question to fix marks or indexes by riveting, hunting or welding. Furthermore, the printing of signs has so far not given satisfactory results.

Un but de la présente invention est de réaliser une boîte telle que définie ci-dessus, à laquelle un ensemble décoratif est associé.An object of the present invention is to produce a box as defined above, with which a decorative assembly is associated.

Ce but est atteint grâce au fait que, dans la boîte telle que définie ci-desus, la face visible du cadran est garnie d'au moins un élément décoratif transparent et taillé, cet élément étant serti dans une calotte qui est noyée dans un logement borgne de la face visible du cadran et collée contre le fond de ce logement.This object is achieved thanks to the fact that, in the box as defined above, the visible face of the dial is furnished with at least one transparent and cut decorative element, this element being set in a cap which is embedded in a housing blind of the visible face of the dial and glued against the bottom of this housing.

Il a en effet été constaté que parmi les éléments susceptibles d'être utilisés comme décoration, les matériaux transparents et taillés tels que le diamant, le saphir, mais aussi le verre, voire le plastique, donnent un résultat esthétiquement satisfaisant. Ces éléments, aux formes trés géométriques, font contraste avec les formes aléatoires que présentent les matières minérales naturelles.It has in fact been found that among the elements capable of being used as decoration, transparent and cut materials such as diamond, sapphire, but also glass, even plastic, give an aesthetically satisfactory result. These elements, with very geometric shapes, contrast with the random shapes presented by natural mineral materials.

Toutefois, la fixation d'un élément ayant la forme d'une pierre taillée sur un cadran en matière minérale naturelle, pose quelques problèmes. Il est hors de question de chasser l'élément dans un trou du cadran, à cause de sa fragilité. Il n'est pas possible non plus de coller l'élément directement sur le cardran, le chatoiement de cet élément étant détruit. Il est donc nécessaire de monter la pierre sur un chaton.However, the fixing of an element having the shape of a cut stone on a dial made of natural mineral material, poses some problems. It is out of the question to drive the element into a hole in the dial, because of its fragility. It is also not possible to stick the element directly on the cardran, the shimmer of this element being destroyed. It is therefore necessary to mount the stone on a kitten.

Il faut de plus que le système de montage du chaton sur le cadran ne provoque aucune surépaisseur.It is also necessary that the mounting system of the kitten on the dial does not cause any excess thickness.

C'est en utilisant une calotte comme chaton, en la noyant dans un logement borgne et en la collant contre le fond de ce logement que tous les problèmes posés ont pu être résolus.It is by using a cap as a kitten, by drowning it in a blind housing and by sticking it against the bottom of this housing that all the problems posed have been able to be resolved.

Cette calotte tient ainsi parfaitement en place l'élément qu'elle contient et elle n'a pas besoin d'être engagée à force dans la paroi latérale de son logement, au risque de faire sauter le cadran. Elle ne crée donc aucune tension interne dans ce dernier et l'aire de son fond suffit largement à une parfaite adhérence.This cap thus perfectly holds the element it contains and it does not need to be forcibly engaged in the side wall of its housing, at the risk of blowing up the dial. It therefore does not create any internal tension in the latter and the area of its bottom is largely sufficient for perfect adhesion.

De plus, dans cette construction, le liseré que forme la calotte entre l'élément décoratif et la matière du cadran souligne encore le contraste recherché.In addition, in this construction, the border formed by the cap between the decorative element and the material of the dial further emphasizes the desired contrast.

La fragilité de la matière minérale naturelle pose, comme cela a été dit ci-dessus, des problèmes difficiles à résoudre.The fragility of natural mineral matter poses, as has been said above, problems which are difficult to solve.

Un autre but de la présente invention est d'affecter au minimum la solidité de la boîte.Another object of the present invention is to minimize the strength of the box.

Ce but est atteint grâce à la structure particulière que présente la boîte de la revendication 2. Dans cette boîte, la face visible du cadran est concave et le logement, destiné à recevoir l'élément, se trouve à la périphérie de ce cadran.This object is achieved thanks to the particular structure presented by the box of claim 2. In this box, the visible face of the dial is concave and the housing, intended to receive the element, is located at the periphery of this dial.

La concavité du cadran solidifie l'ensemble boîte-cadran et en facilite l'usinage. De la sorte, le bord du cadran s'élève jusqu'au niveau du cran de glace. En d'autres termes, le bord du cadran sert de réhaut. Il en résulte donc un espace réduit pour le passage de l'aiguille de minutes. Il est donc indispensable que l'élément prenne un minimum de place en hauteur. C'est pourquoi la calotte est noyée dans le logement. Le trou, bien que relativement profond, n'affecte pas la solidité de l'ensemble. Cela provient probablement du fait qu'il se trouve au voisinage immédiat de la partie la plus solide: la carrure.The concavity of the dial solidifies the box-dial assembly and facilitates machining. In this way, the edge of the dial rises to the level of the notch of ice. In other words, the edge of the dial serves as a flange. This therefore results in a reduced space for the passage of the minute hand. It is therefore essential that the element takes a minimum of space in height. This is why the cap is embedded in the housing. The hole, although relatively deep, does not affect the strength of the assembly. This is probably due to the fact that it is in the immediate vicinity of the strongest part: the middle part.

Les formes d'exécution définies par la revendication 3 assurent une fabrication de la calotte et un sertissage de l'élément qu'elle contient simples et satisfaisants. De plus, ce bord rabattu de la calotte crée un contraste bienvenu avec la face visible du cadran, en particulier s'il est poli et doré ou argenté.The embodiments defined by claim 3 ensure a simple and satisfactory manufacture of the cap and crimping of the element which it contains. In addition, this folded edge of the cap creates a welcome contrast to the visible face of the dial, especially if it is polished and gold or silver.

Dans celles définies par la revendication 4, la profondeur due logement de la calotte est bien inférieure à l'épaisseur du cadran; elle est à peu près égale à la hauteur de la culasse dudit élément, qui est relativement petit.In those defined by claim 4, the depth of housing of the cap is much less than the thickness of the dial; it is approximately equal to the height of the cylinder head of said element, which is relatively small.

Celles définies par les revendications 5 à 7 visent à conférer audit élément un certain éclat, en particulier si cet élément n'est consitué que par un morceau de verre, de cristal, de plastique transparent ou de strass.Those defined by claims 5 to 7 aim to give said element a certain luster, in particular if this element is not made up only by a piece of glass, crystal, transparent plastic or rhinestones.

Enfin, dans celles définies par la revendication 8, l'élément décoratif qui fait office de signe horaire, facilite la lecture de l'heure, sans altérer l'esthétique de la montre.Finally, in those defined by claim 8, the decorative element which acts as a time sign, facilitates the reading of the time, without altering the aesthetics of the watch.

Une forme d'exécution de la boîte de montre selon l'invention et quelques variantes sont décrites ci-après à simple titre d'exemple et en référence au dessin, dans lequel:

  • - la figure 1 est une coupe radiale par "3 h." de la carrure­cadran de cette boîte;
  • - la figure 2 est une vue en élévation avec une partie en coupe d'une pièce de la figure 1 à plus grande échelle, et
  • - la figure 3 est une vue en plan de la pièce représentée à la figure 2.
An embodiment of the watch case according to the invention and some variants are described below by way of example and with reference to the drawing, in which:
  • - Figure 1 is a radial section through "3 h." the square face of this box;
  • FIG. 2 is an elevation view with a sectional section of a part of FIG. 1 on a larger scale, and
  • - Figure 3 is a plan view of the part shown in Figure 2.

La carrure 1, représentée à la figure 1, est faite en une matière minérale naturelle, telle qu'un granit. Elle présente une forure 2 pour le passage d'une tige de mise à l'heure (non représen­tée) de la montre, et un cran de glace 3, destiné à recevoir une glace plate en saphir ou en verre minéral trempé. Cette carrure 1 est venue de fabrication en une pièce avec le cadran 4 de la montre.The middle 1, shown in Figure 1, is made of a natural mineral material, such as granite. It has a bore 2 for the passage of a time-setting rod (not shown) of the watch, and a notch of ice 3, intended to receive a flat sapphire crystal or tempered mineral glass. This middle part 1 came from one-piece production with the dial 4 of the watch.

Cet ensemble carrure/cadran définit un logement 5 destiné à recevoir le mouvement de la montre (non représenté), ainsi que, dans sa périphérie, une bague en métal (non représentée) qui, collée à la carrure, augmente sa solidité.This middle part / dial defines a housing 5 intended to receive the movement of the watch (not shown), as well as, in its periphery, a metal ring (not shown) which, glued to the middle part, increases its solidity.

Le cadran 4 présente une ouverture centrale 6 pour le passage des axes (non représentés) des aiguilles (non représentées) de la montre. La face visible 7 du cadran 4 est concave, ce qui confère la stabilité de l'ensemble carrure/cadran et en facilite l'usinage. Le bord de la face 7 rejoint le fond du cran de glace 3 et fait ainsi office de rehaut. Un logement cylindrique circulaire borgne 8 à fond 9 plat est enfin formé dans la face 7, à la périphérie du cadran 4. Un ensemble décoratif 10, représentant le signe horaire "3 h." est monté dans le logement 8.The dial 4 has a central opening 6 for the passage of the axes (not shown) of the hands (not shown) of the watch. The visible face 7 of the dial 4 is concave, which gives the stability of the middle / dial assembly and facilitates machining. The edge of the face 7 joins the bottom of the notch of ice 3 and thus acts as a flange. A blind circular cylindrical housing 8 with a flat bottom 9 is finally formed in the face 7, at the periphery of the dial 4. A decorative assembly 10, representing the time sign "3 h." is mounted in the housing 8.

L'ensemble 10 est représenté en détail aux figures 2 et 3. Il est constitué essentiellement d'un élément 11 en matériau transpa­rent présentant la taille des diamants, ou toute autre taille offrant un aspect esthétique intéressant. Cet élément 11 comprend ainsi une culasse 12, dans laquelle sont taillées plusieurs facettes 13, et une couronne 14 qui est également facettée et surmontée d'une table 15.The assembly 10 is shown in detail in Figures 2 and 3. It consists essentially of an element 11 of transparent material having the size of the diamonds, or any other size offering an attractive aesthetic appearance. This element 11 includes thus a cylinder head 12, in which several facets 13 are cut, and a crown 14 which is also faceted and surmounted by a table 15.

Pour l'économie de la boîte, l'élément 11 sera constitué de préférence par un morceau de verre, de cristal, de plastique trans­parent ou de strass. Rien toutefois n'exclut l'usage d'un brillant.For the economy of the box, the element 11 will preferably consist of a piece of glass, crystal, transparent plastic or rhinestones. Nothing however excludes the use of a brilliant.

Cet élément 11 est logé dans une calotte 16, dont le fond 17 est plat et la paroi latérale 18 cylindrique circulaire. Le bord supé­rieur 19 de la paroi 18 est rabattu en 19a par dessus le feuilletis 20 de l'élément 11. Il constitue ainsi une sertissure de ce dernier dans la calotte 16, qui le tient donc fermement en place.This element 11 is housed in a cap 16, the bottom 17 is flat and the side wall 18 circular cylindrical. The upper edge 19 of the wall 18 is folded down at 19a over the sheet 20 of the element 11. It thus constitutes a crimping of the latter in the cap 16, which therefore holds it firmly in place.

La calotte 16 est faite de préférence en laiton. La face visible du bord 19a est polie et, de préférence, dorée ou argentée pour créer un contraste avec le granit de la face 7 du cadran 4. Cette calotte pourrait également être faite en or ou en argent.The cap 16 is preferably made of brass. The visible face of the edge 19a is polished and, preferably, gold or silver to create a contrast with the granite of the face 7 of the dial 4. This cap could also be made of gold or silver.

L'ensemble 10 est fixé au cadran 4 par collage du fond 17 de la calotte 16 au fond 9 du logement 8. Pour éviter des tensions inter­nes dans le cadran 4, le diamètre de la calotte 16 sera légèrement inférieur à celui du logement 8.The assembly 10 is fixed to the dial 4 by bonding the bottom 17 of the cap 16 to the bottom 9 of the housing 8. To avoid internal tensions in the dial 4, the diameter of the cap 16 will be slightly less than that of the housing 8.

Comme on le voit à la figure 1, la calotte 16 est entièrement noyée dans le logement 8. C'est donc au plus la couronne 14 de l'élément 11 qui fait saillie de la face 7 du cadran 4. Il reste donc un espace amplement suffisant entre la table 15 de l'élément 11 et la glace (non représentée) de la montre pour le passage des aiguilles.As seen in Figure 1, the cap 16 is fully embedded in the housing 8. It is therefore at most the crown 14 of the element 11 which projects from the face 7 of the dial 4. There therefore remains a space amply sufficient between the table 15 of the element 11 and the crystal (not shown) of the watch for the passage of the hands.

Un signe semblable à celui des figures 2 et 3 est fixé au cadran 4 respectivement à "12 h.", "6 h." et "9 h.". Des signes analogues pourraient naturellement aussi être montés pour chacune des douze heures du cadran. En variante, un seul de ces signes pourrait aussi n'être prévu qu'à "12 h." ou celui-ci se distinguer des autres par exemple par ses dimensions.A sign similar to that of FIGS. 2 and 3 is fixed to the dial 4 respectively at "12 h.", "6 h." and "9 a.m.". Analogous signs could naturally also be fitted for each of the twelve hours of the dial. Alternatively, only one of these signs could also be expected at "12 noon." or this one is distinguished from the others for example by its dimensions.

Lorsque l'élément 11 est réalisé en un matériau vil, il est possible d'obtenir un éclat qui rappelle quelque peu celui du diamant en polissant les faces internes 21 de la calotte 16 au point de réfléchir la lumière traversant l'élément 11. Dans ce cas, l'intérieur de la calotte 16 est avantageusement de forme conique, l'ouverture du cône étant choisie de manière que sa surface soit sensiblement parallèle aux facettes 13. Cette surface peut même être revêtue d'une matière colorée.When the element 11 is made of a base material, it is possible to obtain a luster which somewhat resembles that of the diamond by polishing the internal faces 21 of the cap 16 to the point of reflecting the light passing through the element 11. In in this case, the inside of the cap 16 is advantageously conical, the opening of the cone being chosen so that its surface is substantially parallel to the facets 13. This surface can even be coated with a colored material.

En vue d'obtenir un effet analogue, les facettes 13 de la culasse 12 pourraient aussi être garnies d'une couche réfléchissan­te, colorée ou non.In order to obtain a similar effect, the facets 13 of the cylinder head 12 could also be provided with a reflective layer, colored or not.
