Description

La présente invention est relative à une boîte de montre-bracelet comportant une carrure aménagée pour recevoir un mouvement surmonté d'un cadran et d'aiguilles pour indiquer l'heure, une glace et un fond fixés à la carrure et un bracelet comportant des premier et second brins attachés à ladite carrure respectivement à 6 heures et à 12 heures.The present invention relates to a wristwatch case comprising a middle arranged to receive a movement surmounted by a dial and hands to indicate the time, a crystal and a background fixed to the middle and a bracelet comprising first and second strands attached to said middle respectively at 6 o'clock and at 12 o'clock.

Une foule de possibilités se présentent à qui veut proposer une boîte de montre qui comprenne les composants élémentaires énumérés dans la définition générique donnée ci-dessus. Dans le cas où l'on cherche à donner à la boîte un aspect haut de gamme tout en souhaitant une excellente résistance à l'égard des contraintes extérieures qui peuvent se présenter, notamment la résistance aux rayures, on peut mettre en oeuvre, par exemple, une glace saphir et habiller la carrure d'une coiffe en matériau extra-dur, comme cela est montré dans le brevet CH-A-517 963 (US-A-3 242 664). Dans cette exécution cependant le fond est en acier et son aspect peut rapidement se détériorer. De même la coiffe qui habille la carrure présente une lourde masse tant du point de vue du poids que du point de vue esthétique.There are a host of possibilities for anyone who wants to offer a watch case that includes the basic components listed in the generic definition given above. In the case where it is sought to give the box a high-end appearance while wishing an excellent resistance with regard to the external constraints which may arise, in particular resistance to scratches, it is possible to use, for example , a sapphire crystal and dress the middle of a cap in extra hard material, as shown in patent CH-A-517,963 (US-A-3,242,664). In this version, however, the bottom is made of steel and its appearance can quickly deteriorate. In the same way the cap which dresses the middle has a heavy mass both from the point of view of the weight and from the aesthetic point of view.

Pour pallier ces inconvénients, la boîte de la présente invention, en plus qu'elle comporte les éléments énumérés au premier paragraphe ci-dessus, est caractérisée en ce que le fond recouvre entièrement le dessous de carrure et qu'il comporte des première et seconde ailes faites d'une pièce avec lui, lesdites ailes recouvrant au moins entièrement les flancs extérieurs que présente la carrure et qui se trouvent situés entre les brins du bracelet.To overcome these drawbacks, the box of the present invention, in addition to comprising the elements listed in the first paragraph above, is characterized in that the base entirely covers the underside and that it includes first and second wings made in one piece with it, said wings covering at least entirely the outer sides of the middle and which are located between the strands of the bracelet.

L'invention va être maintenant expliquée à l'aide de la description qui suit, donnée à titre d'exemple, et en s'aidant du dessin qui l'illustre et dans lequel :

  • la figure 1 est une vue en perspective de la montre-bracelet selon l'invention,
  • la figure 2 est une vue en plan selon la flèche II de la figure 1, cette vue représentant le quartier de la montre situé entre 3 heures et 6 heures,
  • la figure 3 est une coupe à 3 heures selon la ligne III-III de la figure 1,
  • la figure 4 est une coupe à 6 heures selon la ligne IV-IV de la figure 1,
  • la figure 5 est une vue de dessus et en plan du fond de la montre,

  • la figure 10 est une coupe selon la ligne X-X de la figure 8,
  • la figure 11 est une vue de face d'un maillon de bracelet attenant à la boîte selon la flèche XI de la figure 1, et
  • la figure 12 est une coupe à 3 heures montrant une variante d'exécution de celle présentée en figure 3.
The invention will now be explained with the aid of the description which follows, given by way of example, and with the aid of the drawing which illustrates it and in which:
  • FIG. 1 is a perspective view of the wristwatch according to the invention,
  • FIG. 2 is a plan view according to arrow II in FIG. 1, this view representing the quarter of the watch located between 3 am and 6 am,
  • FIG. 3 is a section at 3 o'clock along the line III-III of FIG. 1,
  • FIG. 4 is a section at 6 o'clock along the line IV-IV of FIG. 1,
  • FIG. 5 is a top and plan view of the bottom of the watch,
  • FIG. 6 is a section of the bottom along the line VI-VI of FIG. 5,
  • FIG. 7 is a bottom view along arrow VII of FIG. 5,
  • FIG. 8 is a view from above and in plan of the middle of the watch represented by a quarter situated between 3 am and 6 am,
  • FIG. 9 is a section along the line IX-IX of FIG. 8,
  • FIG. 10 is a section along line XX of FIG. 8,
  • FIG. 11 is a front view of a bracelet link adjoining the box according to arrow XI in FIG. 1, and
  • FIG. 12 is a section at 3 o'clock showing an alternative embodiment of that presented in FIG. 3.

La figure 1 présente l'aspect général de la montre selon l'invention. Sur cette figure apparaît une glace 5, un cadran 3 et des aiguilles 4. Un fond 6 est fait d'une pièce avec une aile 9 qui remonte le long du flanc d'une carrure portant un mouvement, la carrure et le mouvement n'étant pas visibles ici. Emergeant de l'aile 9, on voit une couronne 30 qui sert à la mise à l'heure de la montre. La figure 1 montre qu'un brin 7 d'un bracelet, respectivement un brin 8, sont fixés à la montre-bracelet, des pièces en forme d'étrier ou embouts 18 étant interposés entre les extrémités des brins 7 et 8 et la montre-bracelet.Figure 1 shows the general appearance of the watch according to the invention. In this figure appears a crystal 5, a dial 3 and hands 4. A base 6 is made in one piece with a wing 9 which rises along the side of a middle carrying a movement, the middle and the movement n ' not being visible here. Emerging from wing 9, there is a crown 30 which is used for setting the time of the watch. FIG. 1 shows that a strand 7 of a bracelet, respectively a strand 8, are fixed to the wristwatch, pieces in the shape of a stirrup or end pieces 18 being interposed between the ends of the strands 7 and 8 and the watch -bracelet.

Si l'on examine maintenant les figures 2, 3 et 4 qui présentent respectivement une vue en plan selon la flèche II de la figure 1, et des coupes selon les lignes III-III et IV-IV de la même figure 1, on voit que la montre comporte une carrure 12 aménagée pour recevoir un mouvement 2. Le mouvement est surmonté d'un cadran 3 et d'aiguilles 4 pour indiquer l'heure. Une glace 5 et un fond 6 sont fixés à la carrure 12. Un premier brin 7 du bracelet est fixée à 6 heures de la carrure 12, comme on le voit sur la figure 4. Un second brin 8, non représenté en figure 4 (voir figure 1), est fixé à 12 heures de la carrure 12.If we now examine Figures 2, 3 and 4 which respectively show a plan view along arrow II of Figure 1, and sections along lines III-III and IV-IV of the same Figure 1, we sees that the watch has a middle 12 arranged to receive a movement 2. The movement is surmounted by a dial 3 and hands 4 to indicate the time. A crystal 5 and a bottom 6 are fixed to the middle 12. A first strand 7 of the bracelet is fixed at 6 o'clock in the middle 12, as seen in FIG. 4. A second strand 8, not shown in FIG. 4 ( see figure 1), is set at 12 o'clock in the middle 12.

Selon une caractéristique essentielle de l'invention, le fond 6 recouvre entièrement le dessous de carrure 12 et comporte des première et seconde ailes faites d'une pièce avec lui, ces ailes recouvrant au moins entièrement les flancs extérieurs 11 que présente la carrure. Le fond 6 est représenté en plan à la figure 5 et la carrure 12 est représentée également en plan à la figure 8. Si l'on superpose la figure 8 et la figure 5, on s'aperçoit que le fond 6 recouvre entièrement le dessous de la carrure 12. D'autre part, les figures 5 et 6 montrent que le fond 6 comporte une première aile 9 et une seconde aile 10 faites d'une pièce avec le fond. L'aile 9 recouvre entièrement le flanc 11 de la carrure 12, comme on le voit en figure 3 et comme on le voit aussi en superposant la figure 8 et la figure 5 ainsi que la figure 10 et la figure 6. L'aile 10 recouvre également entièrement le flanc 11 de la carrure 12 bien que cela ne soit pas représenté au dessin, la figure 8 ne présentant qu'un quartier 3 heures - 6 heures de la carrure 12. Il est à remarquer que seuls les flancs extérieurs 11 de la carrure qui se trouvent situés entre les embouts 18 sont recouverts par les ailes 9 et 10 du fond 6, c'est-à-dire, comme on le voit bien en figure 1, les flancs situés dans les zones 3 heures et 9 heures.According to an essential characteristic of the invention, the base 6 completely covers the underside of the middle 12 and comprises first and second wings made in one piece with it, these wings covering at least entirely the outer sides 11 which the middle has. The bottom 6 is shown in plan in Figure 5 and the middle 12 is also shown in plan in Figure 8. If we superimpose Figure 8 and Figure 5, we see that the bottom 6 completely covers the underside of the middle part 12. On the other hand, Figures 5 and 6 show that the bottom 6 has a first wing 9 and a second wing 10 made in one piece with the bottom. The wing 9 completely covers the side 11 of the middle 12, as can be seen in FIG. 3 and as also seen by superimposing FIG. 8 and FIG. 5 as well as FIG. 10 and FIG. 6. The wing 10 also completely covers the side 11 of the middle 12 although this is not shown in the drawing, FIG. 8 showing only a quarter between 3 and 6 o'clock of the middle 12. It should be noted that only the external sides 11 of the middle which are located between the end pieces 18 are covered by the wings 9 and 10 of the base 6, that is to say, as can be seen in FIG. 1, the sides situated in the 3 o'clock and 9 o'clock zones .

La figure 3 montre que la première aile 9 est recouverte par la glace 5, cette dernière débordant de la carrure 12. Cette même figure montre qu'un léger jeu est laissé entre l'aile 9 et la glace 5, ceci pour absorber les différences qu'on constate dans les dimensions du fond surtout si ce dernier est fait en matériau mouléfritté, comme de la céramique par exemple. De même, on aura soin de ménager un assez fort arrondi sur l'arête 31 de l'aile 9 de telle manière que l'espace entre l'aile et la glace soit le moins apparent possible.Figure 3 shows that the first wing 9 is covered by the glass 5, the latter projecting from the middle 12. This same figure shows that a slight clearance is left between the wing 9 and the glass 5, this to absorb the differences that we see in the dimensions of the bottom especially if the latter is made of molded sintered material, such as ceramic for example. Likewise, care will be taken to provide a fairly strong rounded shape on the edge 31 of the wing 9 so that the space between the wing and the glass is as invisible as possible.

La figure 12 montre une variante de construction par rapport à celle présentée en figure 3. On voit en figure 12 que l'aile 9 recouvre le flanc 13 de la glace 5, de sorte que le flanc de glace se trouve situé à fleur du flanc extérieur 11 de la carrure 12.Figure 12 shows a construction variant compared to that presented in Figure 3. We see in Figure 12 that the wing 9 covers the side 13 of the glass 5, so that the side of ice is located flush with the side outside 11 of middle part 12.

On donnera maintenant des explications sur une façon d'attacher les brins du bracelet à la carrure.We will now give explanations on how to attach the strands of the bracelet to the middle part.

Les figures 2, 4, 8 et 9 montrent que la carrure 12 est pourvue à 6 heures d'un prolongement 14 s'étendant dans la direction longitudinale du brin 7. Bien que non représenté, la carrure 12 est également pourvue à 12 heures d'un prolongement 15 s'étendant dans la direction longitudinale du brin 8. Les prolongements 14 et 15 servent d'attache aux brins sur la carrure, comme on le voit à la figure 4. Le prolongement 14 est recouvert par un élément ou embout 18 en forme d'étrier qui est représenté seul en figure 11. Cet élément est glissé sur le prolongement 14 avant le montage du brin 7 proprement dit. L'extrémité du prolongement 14 porte un charneron 32 sur lequel est articulée une plaque 33 munie de gonds et arrangée pour recevoir un premier maillon 34 du brin 7, mobile celui-là.Figures 2, 4, 8 and 9 show that the middle 12 is provided at 6 o'clock with an extension 14 extending in the longitudinal direction of the strand 7. Although not shown, the middle 12 is also provided at 12 o'clock d 'an extension 15 extending in the longitudinal direction of the strand 8. The extensions 14 and 15 serve to attach the strands to the middle part, as seen in Figure 4. The extension 14 is covered by an element or end piece 18 in the form of a stirrup which is shown alone in FIG. 11. This element is slid over the extension 14 before the strand 7 itself is assembled. The end of the extension 14 carries a hinge 32 on which is hinged a plate 33 provided with hinges and arranged to receive a first link 34 of the strand 7, mobile that one.

Les figures 4, 5 et 7 montrent que le fond 6 comporte également des prolongements 16 et 17 qui recouvrent au moins partiellement les prolongements 14 et 15 de la carrure 12. Ces prolongements 16 et 17 prennent place entre les extrémités 35 et 36 présentées par l'étrier 18 (figure 11), l'étrier 18 recouvrant le reste des prolongements de la carrure qui ne sont pas recouverts par les prolongements du fond.Figures 4, 5 and 7 show that the bottom 6 also includes extensions 16 and 17 which at least partially cover the extensions 14 and 15 of the middle part 12. These extensions 16 and 17 take place between the ends 35 and 36 presented by l 'caliper 18 (Figure 11), the caliper 18 covering the rest of the extensions of the middle part which are not covered by the extensions of the bottom.

Le fond 6 est fixé à la carrure 12 par des vis 19 (figure 4) traversant des passages 20 pratiqués dans les prolongements 16 et 17 du fond 6, ces vis étant vissées dans des taraudages 21 pratiqués dans les prolongements 14 et 15 de la carrure 12 (voir aussi figures 2, 5, 6, 7, 8 et 9).The bottom 6 is fixed to the middle part 12 by screws 19 (FIG. 4) passing through passages 20 made in the extensions 16 and 17 of the bottom 6, these screws being screwed into threads 21 made in the extensions 14 and 15 of the middle part 12 (see also Figures 2, 5, 6, 7, 8 and 9).

La glace 5 est fixée à la carrure 12 par collage ou soudage (figures 3 et 4). Pour escamoter ce moyen de fixation et du même coup le haut de la carrure, on appose une métallisation 37 sous la glace.The crystal 5 is fixed to the middle part 12 by gluing or welding (Figures 3 and 4). To retract this fixing means and at the same time the top of the middle part, a metallization 37 is affixed under the glass.

On dira maintenant quelques mots sur la façon de monter le movement dans la boîte. Un cercle d'encageage 22 est interposé entre le mouvement 2 et la carrure 12 (voir aussi figures 3 et 4). Le mouvement 2 est porté par le filet 41 qu'il présente, filet qui repose dans un logement 40 du cercle 22. Une garniture 23 est comprimée entre le fond 6 et un logement 24 pratiqué à la fois dans le cercle 22 et dans la carrure 12 (voir figures 8, 9 et 10). La carrure comporte encore un réhaut 25 fait d'une pièce avec elle. Sous le réhaut 25 appuie le cadran 3 quand le fond 6 est fixé à la carrure 12 au moyen des vis 19. L'emboîtage a lieu par dessous.We will now say a few words on how to mount the movement in the box. A casing ring 22 is interposed between the movement 2 and the middle 12 (see also Figures 3 and 4). The movement 2 is carried by the net 41 which it presents, a net which rests in a housing 40 of the circle 22. A lining 23 is compressed between the bottom 6 and a housing 24 made both in the circle 22 and in the middle 12 (see FIGS. 8, 9 and 10). The middle part also has a flange 25 made in one piece with it. Under the flange 25 supports the dial 3 when the base 6 is fixed to the middle part 12 by means of the screws 19. The casing takes place from below.

La description qui vient d'être faite a montré que la montre de l'invention est facile à fabriquer et présente une allure très légère bien que possédant un fort blindage résistant aux rayures, à condition bien entendu que le fond avec ses ailes soient réalisés en métal dur ou en céramique dont la dureté dépasse ou est égale à 1000 HV. Les maillons des brins du bracelet seront réalisés de préférence dans un même matériau que celui utilisé pour le fond.The description which has just been made has shown that the watch of the invention is easy to manufacture and has a very light appearance although having a strong armor resistant to scratches, provided of course that the back with its wings are made in hard metal or ceramic whose hardness exceeds or is equal to 1000 HV. The links of the strands of the bracelet will preferably be made of the same material as that used for the background.

On notera aussi que toutes les parties fonctionnelles, soit attache des brins du bracelet, positionnement du mouvement et de la glace, fixation du fond se réfèrent à la seule carrure, elle-même réalisée en métal usuel. La traction due au bracelet s'exerce donc sur la carrure et non sur un matériau mal adapté à des forces de traction. Si les brins du bracelet 7 et 8, les embouts 18 et le fond 6 avec ses ailes 9 et 10 sont faits en céramique, la pièce d'horlogerie présente une esthétique unitaire, à savoir qu'elle est habillée entièrement de céramique à l'exception bien sûr de la glace.It will also be noted that all the functional parts, either attaching the strands of the bracelet, positioning of the movement and of the crystal, fixing of the base refer to the sole middle, itself made of usual metal. The traction due to the bracelet is therefore exerted on the middle part and not on a material poorly adapted to traction forces. If the strands of the bracelet 7 and 8, the end pieces 18 and the bottom 6 with its wings 9 and 10 are made of ceramic, the timepiece has a unitary aesthetic, namely that it is entirely dressed in ceramic exception of course of ice.

Les figures qui accompagnent ce texte présentent une boîte de forme rectangulaire assortie d'une glace bombée. La présente invention n'est pas limitée bien sûr à cette forme d'exécution donnée seulement à titre d'exemple. On pourrait, par exemple, avoir une glace plate ou sphérique. On pourrait aussi avoir une boîte ronde, voire polygonale. Dans ce cas, les ailes du fond ne seraient plus rectilignes mais arrondies ou de forme entre les attaches de bracelet.The figures accompanying this text present a rectangular box with a curved glass. The present invention is not of course limited to this embodiment given only by way of example. We could, for example, have a flat or spherical glass. We could also have a round, even polygonal, box. In this case, the wings of the bottom would no longer be straight but rounded or shaped between the strap attachments.

On notera pour terminer que la construction proposée est économique surtout par la manière de réaliser le fond dans un matériau dur et cassant, ce fond habillant la carrure en remontant le long de ses flancs, les fonctions mécaniques et d'étanchéité étant remplies par la carrure en métal.Finally, it should be noted that the proposed construction is economical, above all by the manner of producing the base in a hard and brittle material, this base covering the middle by going up along its sides, the mechanical and sealing functions being fulfilled by the middle. made of metal.
