Abstract

The rim (1) carrying the glass (1) is fixed to the bottom (3) by any means so that its lower surface bears against the junction surface (7). The clockwork (9) which carries the dial (10) is supported by the ring (11). The latter is held axially in place between two shoulders of the bottom (3) and of the rim (2) which are both located at an offset position with respect to the surface of the junction (7). Sealing packings (15 and 16) are provided between the two faces of the ring (11) and said shoulders while the side surfaces of the ring (11) provide for the positioning of the ring with respect to the bottom. The tube (17) which provides for the sealing of the control rod is machined in one piece with the ring (11).

Description

La présente invention a pour objet une boîte de montre étanche comprenant une lunette, un verre, un fond fixé à la lunette de manière amovible par des moyens qui sont localisés sur le pourtour de la lunette et du fond, et un élément intermédiaire qui comporte une partie annulaire, qui est destiné à maintenir le mouvement en place, et qui est logé entre le fond et la lunette, ces deux derniers éléments présentant un plan de jonction situé à un niveau intermédiaire entre les faces supérieure et inférieure de l'élément intermédiaire.The subject of the present invention is a waterproof watch case comprising a bezel, a glass, a bottom fixed to the bezel in a removable manner by means which are located on the periphery of the bezel and the bottom, and an intermediate element which comprises a annular part, which is intended to keep the movement in place, and which is housed between the bottom and the bezel, these last two elements having a junction plane located at an intermediate level between the upper and lower faces of the intermediate element.

Actuellement, la construction des boîtes de montre étanches se heurte aux problèmes posés par l'exigence de réalisations aussi minces que possible, dans lequelles l'étanchéité est assurée d'une façon parfaite et dont la forme doit pouvoir être choisie à volonté, c'est-à-dire différer d'une forme circulaire. Les exigences de la pratique s'étendent également à la simplicité de fabrication, à la rigidité des pièces, à l'esthétique et à la facilité de démontage, notamment en vue du changement des piles dans le cas des montres électroniques.Currently, the construction of waterproof watch cases faces the problems posed by the requirement of as thin as possible embodiments, in which the sealing is ensured in a perfect way and whose shape must be able to be chosen at will, it that is, differ from a circular shape. The requirements of the practice also extend to the simplicity of manufacture, the rigidity of the parts, the aesthetics and the ease of disassembly, in particular with a view to changing the batteries in the case of electronic watches.

Une boîte de montre du genre défini ci-dessus est déjà connue par le brevet suisse CH-B-619 345. Dans cette construction, toutefois, le fait que le fond et la lunette présentent un plan de jonction situé à un niveau intermédiaire entre les faces supérieure et inférieure de l'élément intermédiaire n'est pas utilisé pour permettre une réalisation de hauteur réduite. En particulier l'élément intermédiaire doit être suffisamment épais pour pouvoir présenter des bourrelets saillants et superposés assurant séparément la fixation du fond et celle de la lunette, à cet élément intermédiaire.A watch case of the kind defined above is already known from Swiss patent CH-B-619,345. In this construction, however, the fact that the back and the bezel have a junction plane situated at an intermediate level between the upper and lower faces of the intermediate element is not used to allow a reduced height to be produced. In particular, the intermediate element must be thick enough to be able to present projecting and superimposed beads ensuring the attachment of the bottom and that of the bezel, to this intermediate element.

D'autres boîtes de montres du même genre sont également connues par les publications DE-A-1523843 et CH-A-580833 (mémoire exposé 2363/69).Other watch boxes of the same kind are also known from the publications DE-A-1523843 and CH-A-580833 (memoir 2363/69).

Or, dans ces autres constructions également il n'est pas possible de prévoir des réalisations fiables et étanches, présentant une épaisseur suffisamment réduite pour s'adapter aux épaisseurs très réduites des mouvements de montres actuels. Ces constructions de boîtes ne permettent donc pas aux utilisateurs de bénéficier grâce à la fourniture d'un habillement convenable, des efforts qui ont été faits récemment pour réduire l'épaisseur des mouvements. On sait à ce propos que dans certains cas, cette épaisseur ne dépasse que de peu un millimètre.However, in these other constructions also it is not possible to provide reliable and waterproof constructions, having a thickness sufficiently reduced to adapt to the very reduced thicknesses of current watch movements. These box constructions therefore do not allow users to benefit from the provision of suitable clothing, the efforts which have been made recently to reduce the thickness of the movements. We know in this connection that in certain cases, this thickness only exceeds a little a millimeter.

Or, en règle générale, les boîtes de montre doivent être équipées sur leur côté, de préférence sur trois heures, de moyens de guidage et de soutien étanches pour une tige de commande qui porte à son extrémité extérieure une couronne et qui pénètre dans le mouvement où elle assure certaines fonctions en réponse à des mouvements effectués par l'utilisateur. Ces moyens de guidage comportent une pièce indépendante en forme de tube qui est fixée à la lunette, à la paroi du fond, ou le cas échéant à la pièce intermédiaire.However, as a general rule, watch cases must be fitted on their side, preferably over three hours, with watertight guide and support means for a control rod which carries a crown at its outer end and which enters the movement where it performs certain functions in response to movements made by the user. These guide means comprise an independent tube-shaped part which is fixed to the telescope, to the back wall, or where appropriate to the intermediate part.

Dans les constructions décrites par les documents DE-A-1 523 843 et CH-A-580 833, ce tube est engagé dans la paroi latérale de la pièce intermédiaire. De plus, dans un cas (DE-A-1 523 843), les moyens de fixation du fond à la lunette sont constitués par un engagement à cran ou à serrage radial qui s'étend sur tout le tour de la boîte, en dessous du tube. Dans l'autre cas, la pièce intermédiaire n'est pas un anneau, mais comporte elle-même un fond qui vient se superposer au fond proprement dit.In the constructions described by documents DE-A-1 523 843 and CH-A-580 833, this tube is engaged in the side wall of the intermediate piece. In addition, in one case (DE-A-1 523 843), the means for fixing the bottom to the bezel are constituted by a notch or radial tightening engagement which extends over the entire circumference of the case, below of the tube. In the other case, the intermediate piece is not a ring, but itself comprises a bottom which comes to be superimposed on the bottom itself.

Les documents CH-B-506 829 et FR-A-2 025 630 décrivent aussi les boîtes de montres dans lesquelles un élément intermédiaire portant le mouvement est enfermé entre un fond et une lunette, cette dernière assurant le maintien du verre. Cependant, le plan de jonction est situé dans ces constructions, hors des limites des faces supérieure et inférieure de l'élément intermédiaire. En outre, ces documents ne suggèrent aucun moyen permettant de réduire l'épaisseur de l'élément intermédiaire tout en assurant au passage de la tige de commande un diamètre interne suffisant pour qu'une tige suffisamment rigide puisse être guidée dans ce passage.Documents CH-B-506 829 and FR-A-2 025 630 also describe watch cases in which an intermediate element carrying the movement is enclosed between a caseback and a bezel, the latter ensuring the maintenance of the glass. However, the junction plane is located in these constructions, outside the limits of the upper and lower faces of the intermediate element. Furthermore, these documents do not suggest any means making it possible to reduce the thickness of the intermediate element while ensuring the passage of the control rod an internal diameter sufficient for a sufficiently rigid rod to be guided in this passage.

La présente invention a pour but de surmonter cette difficulté.The object of the present invention is to overcome this difficulty.

Elle a pour objet une boîte de montre du genre mentionné au début, caractérisée en ce que l'élément intermédiaire comporte un organe métallique formé d'une pièce unique comprenant ladite partie annulaire et un prolongement radial externe, compris en hauteur entre les dites faces supérieure et inférieure, s'étendant jusqu'à l'extérieur de la boîte entre le fond et la lunette, et percé d'un passage pour l'engagement direct d'une tige de commande du mouvement, et en ce que lesdits moyens sont indépendants de l'organe intermédiaire et sont localisés en des emplacements différents de celui du prolongement radial.It relates to a watch case of the kind mentioned at the beginning, characterized in that the intermediate element comprises a metal member formed of a single piece comprising said annular part and an external radial extension, included in height between said upper faces and lower, extending to the outside of the box between the bottom and the bezel, and pierced with a passage for the direct engagement of a motion control rod, and in that said means are independent of the intermediate member and are located at different locations from that of the radial extension.

On va décrire ci-après, à titre d'exemple, deux formes de réalisation de l'objet de l'invention en se référant au dessin annexé dont :

  • la figure 1 est une vue en coupe axiale partielle selon l'axe 12 h-6 h, de la première forme d'exécution,
  • la figure 2 une vue analogue à la fig. 1 selon l'axe 3 h-9 h.
  • la figure 3 une vue en élévation selon l'axe 3 h-9 h à plus petite échelle,
  • la figure 4 une vue en plan de dessus à la même échelle que la fig. 3,
  • la figure 5 une vue en coupe selon l'axe 3 h-9 h de la seconde forme d'exécution,
  • la figure 6 une vue en coupe de cette seconde forme d'exécution selon l'axe 6 h-12 h, et
  • la figure 7 une vue en coupe de cette seconde forme d'exécution selon un axe oblique passant par les vis de fixation.
Two embodiments of the subject of the invention will be described below, by way of example, with reference to the appended drawing, of which:
  • FIG. 1 is a view in partial axial section along the axis between 12 pm and 6 am, of the first embodiment,
  • Figure 2 a view similar to FIG. 1 along the line 3 a.m. to 9 a.m.
  • FIG. 3 a view in elevation along the axis 3 h-9 h on a smaller scale,
  • Figure 4 a top plan view on the same scale as FIG. 3,
  • FIG. 5 a sectional view along the axis 3 h-9 h of the second embodiment,
  • FIG. 6 is a sectional view of this second embodiment along the axis from 6 am to 12 pm, and
  • Figure 7 a sectional view of this second embodiment along an oblique axis passing through the fixing screws.

Comme on le voit aux fig. 1 et 2, les parties visibles de la boîte décrite sont constituées par le verre 1, la lunette 2 et le fond 3. Le verre 1 est de préférence un verre minéral. Il est fixé dans une saignée annulaire 4 de la lunette 2 par des moyens connus par exemple par engagement à force ou collage. Dans la forme d'exécution décrite, la boîte est une boîte de forme rectangulaire à côtés latéraux arrondis, comme on le voit à la fig. 4. Le verre et la lunette présentent cette même forme, mais il est bien entendu que la boîte pourrait également être réalisée sous forme de boîte circulaire ou de toute autre forme.As seen in Figs. 1 and 2, the visible parts of the box described consist of the glass 1, the bezel 2 and the bottom 3. The glass 1 is preferably a mineral glass. It is fixed in an annular groove 4 of the telescope 2 by known means for example by force engagement or bonding. In the embodiment described, the box is a rectangular box with rounded lateral sides, as seen in FIG. 4. The glass and the bezel have this same shape, but it is understood that the box could also be made in the form of a circular box or any other shape.

La forme extérieure du fond 3 correspond à celle de la lunette 2 à l'exception des parties extrêmes 5 qui forment des renflements saillants et qui présentent une forme de parallélépipède se raccordant à la forme des premiers maillons du bracelet. Les détails de la fixation du bracelet aux éléments saillants 5 du fond 3 ne jouent pas de rôle en ce qui concerne la présente invention et ne seront pas décrits ici. Ces éléments saillants 5 sont limités du côté de l'intérieur par des faces planes internes 6 qui s'étendent jusqu'à un épaulement 7. La lunette 2 présente une face inférieure plane qui est conformée de façon à s'appuyer sur l'épaulement 7. Latéralement elle- est limitée selon l'axe midi-6 h par deux surfaces frontales qui s'engagent à l'intérieur de la surface 6 lors de la fermeture de la boîte. Des vis 8 partiellement vissées dans des échancrures correspondantes de la lunette et du fond assurent la fixation rigide des deux pièces l'une à l'autre.The outer shape of the bottom 3 corresponds to that of the bezel 2 with the exception of the end portions 5 which form protruding bulges and which have a shape of parallelepiped connecting to the shape of the first links of the bracelet. The details of the attachment of the bracelet to the projecting elements 5 of the bottom 3 do not play a role with regard to the present invention and will not be described here. These projecting elements 5 are limited on the interior side by internal flat faces 6 which extend to a shoulder 7. The bezel 2 has a flat lower face which is shaped so as to bear on the shoulder 7. Laterally, it is limited along the noon-6 o'clock axis by two frontal surfaces which engage inside the surface 6 when the box is closed. Screws 8 partially screwed into corresponding notches of the bezel and the bottom ensure the rigid attachment of the two parts to one another.

La boîte est destinée à contenir un mouvement mécanique ou électronique 9 qui sera en général de forme circulaire et qui porte un cadran 10. Pour supporter le mouvement 9, on prévoit un élément intermédiaire de forme annulaire 11 qui joue le. rôle de cercle d'encageage. Cette pièce, qui est en métal, a un contour interne circulaire avec une collerette supportant le filet de platine du mouvemèht 9 de façon à permettre la fixation de ce mouvement au cercle 11 par des clés de fixation usuelles. Pour s'adapter à une boîte de forme non circulaire comme celle représentée au dessin, le contour extérieur du cercle 11 a une allure cylindrique circulaire dans sa partie inférieure et une forme semblable à celle de la boîte dans sa partie supérieure. Ainsi, les faces 12 et 13 (fig. 2) du cercle 11 ont respectivement une forme rectangulaire à côtés arrondis et circulaire. Entre elles est ménagé un épaulement 14 qui s'étend dans les zones situées le long des côtés latéraux au-dessus de la partie interne de l'épaulement de jonction 7. De plus, pour assurer le positionnement du cercle 11, deux garnitures d'étanchéité annulaires 15 et 16 sont prévues. La garniture 15 est pincée entre un épaulement circulaire du fond et la surface inférieure du cercle 11 tandis que la garniture 16 qui a la forme de la boîte est pincée entre un épaulement de la lunette situé à la base du réhaut et la surface supérieure du cercle 11. Dans la forme d'exécution décrite, le mouvement 9 comporte une tige de commande, par exemple une tige de remontoir et de mise à l'heure qui fait saillie du mouvement radialement sur 3 h. Pour permettre le passage de cette tige, le cercle 11 est usiné sous forme d'une pièce unique avec un prolongement radial 17 qui est percé d'un passage cylindrique désigné par 11a. Ce prolongement radial s'étend vers l'extérieur sur une distance suffisante pour que, lorsque la pièce 11 est emboîtée, il fasse saillie à l'extérieur du fond et de la lunette ou tout au moins apparaisse dans des saignées radiales 18 et 19 qui sont ménagées dans ces pièces. Le passage 11 a est un trou cylindrique d'un diamètre suffisant pour permettre le passage d'une tige de commande du mouvement. L'ensemble du prolongement radial 17 s'étend en hauteur entre les faces supérieure et inférieure de la pièce 11.The box is intended to contain a mechanical or electronic movement 9 which will generally be circular and which carries a dial 10. To support the movement 9, an intermediate element of annular form 11 is provided which plays on. role of casing circle. This piece, which is made of metal, has a circular internal contour with a flange supporting the platinum thread of the movement 9 so as to allow the fixing of this movement to the circle 11 by usual fixing keys. To adapt to a non-circular box like that shown in the drawing, the outer contour of the circle 11 has a circular cylindrical shape in its lower part and a shape similar to that of the box in its upper part. Thus, the faces 12 and 13 (fig. 2) of the circle 11 respectively have a rectangular shape with rounded and circular sides. Between them is provided a shoulder 14 which extends in the zones situated along the lateral sides above the internal part of the joining shoulder 7. In addition, to ensure the positioning of the circle 11, two linings of ring seals 15 and 16 are provided. The lining 15 is pinched between a circular shoulder of the bottom and the lower surface of the circle 11 while the lining 16 which has the shape of the box is pinched between a shoulder of the bezel located at the base of the flange and the upper surface of the circle 11. In the embodiment described, the movement 9 comprises a control rod, for example a winding and time-setting rod which projects from the movement radially over 3 h. To allow the passage of this rod, the circle 11 is machined in the form of a single part with a radial extension 17 which is pierced with a cylindrical passage designated by 11a. This radial extension extends outward over a sufficient distance so that, when the part 11 is fitted, it projects outside the bottom and of the bezel or at least appears in radial grooves 18 and 19 which are arranged in these rooms. The passage 11a is a cylindrical hole of sufficient diameter to allow the passage of a movement control rod. The entire radial extension 17 extends in height between the upper and lower faces of the part 11.

Pour réaliser la pièce 11, on commencera par découper à l'étampe une pièce annulaire présentant un prolongement radial et limitée par une face supérieure et une face inférieure qui sont planes. Le cas échéant, la partie externe du prolongement radial peut être étampée avec un bourrelet afin de faciliter l'usinage, après quoi le prolongement radial sera tourné sur sa face extérieure afin de présenter une allure cylindrique s'engageant entre les échancrures en arc de cercle 18a et 19a de la lunette et du fond. On voit que ce prolongement joue le rôle du tube usuel dans les boîtes de montre étanches. Comme la surface de jonction 7 entre la lunette et le fond est situé en hauteur entre les parties supérieure et inférieure du tube 17, le cercle 11 est partiellement engagé dans la lunette et dans le fond sur tout son pourtour. Les saignées radiales 18 et 19 qui embrassent le tube 17, embrasseront également une couronne de commande 20 (fig. 4) qui sera montée de façon étanche sur la tige selon une des différentes constructions connues dans les boîtes classiques. Ces échancrures sont également visibles à la fig. 3.To produce the part 11, we will begin by cutting an annular part with the stamp having a radial extension and limited by an upper face and a lower face which are planar. If necessary, the external part of the radial extension can be stamped with a bead in order to facilitate machining, after which the radial extension will be turned on its external face in order to present a cylindrical shape engaging between the notches in an arc of a circle. 18a and 19a of the bezel and the back. We see that this extension plays the role of the usual tube in waterproof watch cases. As the junction surface 7 between the telescope and the bottom is located in height between the upper and lower parts of the tube 17, the circle 11 is partially engaged in the telescope and in the bottom over its entire periphery. The radial grooves 18 and 19 which embrace the tube 17 will also embrace a control crown 20 (fig. 4) which will be mounted in leaktight manner on the rod according to one of the various constructions known in conventional boxes. These notches are also visible in fig. 3.

Dans le cas où le mouvement 9 comporte plusieurs tiges de commande, par exemple une tige de remontoir et un poussoir, ou, dans le cas de montres digitales, plusieurs poussoirs, le cerlce 11 sera pourvu d'autant de tubes 17 qu'il y aura d'organes de commande au mouvement.In the case where the movement 9 comprises several control rods, for example a winding rod and a push-button, or, in the case of digital watches, several push-buttons, the cerlce 11 will be provided with as many tubes 17 as there are will have control elements to the movement.

Comme on l'a déjà mentionné, la boîte décrite peut être réalisée dans n'importe quelle forme. En particulier, la construction décrite permet aussi de réaliser des boîtes circulaires. D'autres variantes d'exécution sont également possibles en ce qui concerne l'agencement des moyens d'étanchéité et la fixation du cercle 11. Le cas échéant, les moyens d'étanchéité pourraient consister en une pièce unique à profil en U entourant complètement les faces extérieures de la pièce unique 11. Cette exécution conviendrait dans le cas où la partie inférieure et la partie supérieure de l'élément intermédiaire seraient de même forme et de mêmes dimensions.As already mentioned, the described box can be made in any shape. In particular, the construction described also makes it possible to produce circular boxes. Other alternative embodiments are also possible as regards the arrangement of the sealing means and the fixing of the circle 11. If necessary, the sealing means could consist of a single piece with U-profile completely surrounding the outer faces of the single part 11. This embodiment would be suitable in the case where the lower part and the upper part of the intermediate element are of the same shape and the same dimensions.

Tel qu'il est représenté à la fig. 2, le cercle 11 est dimensionné de façon que son épaulement 14 ne repose pas sur la surface de jonction 7 lorsque la boîte est fermée. Les faces latérales 12 et 13 du fond 3 et de la lunette 2 sont ajustées de façon que le cercle 11 glisse librement entre ces éléments, de sorte que les garnitures d'étanchéité 15 et 16 assurent également la suspension élastique du mouvement.As shown in fig. 2, the circle 11 is dimensioned so that its shoulder 14 does not rest on the junction surface 7 when the box is closed. The lateral faces 12 and 13 of the bottom 3 and of the bezel 2 are adjusted so that the circle 11 slides freely between these elements, so that the seals 15 and 16 also provide the elastic suspension of the movement.

Toutefois, selon une caractéristique additionnelle de l'invention appliquée à la seconde forme d'exécution décrite ci-après, le cercle 11 est conformé de façon qu'au moment de la fermeture de la boîte, il soit bloqué entre le fond et la lunette.However, according to an additional characteristic of the invention applied to the second embodiment described below, the circle 11 is shaped so that when the box is closed, it is blocked between the bottom and the bezel .

Dans cette seconde forme d'exécution, un élément intermédiaire 21 forme une pièce unique avec un prolongement radial 22 qui est percé d'un passage 23 pour la tige de commande du mouvement. L'élément intermédiaire 21 comprend ici une première partie annulaire 24 qui est en acier comme la partie tubulaire 22 et une partie annulaire préminente 25 qui est en or et fixé sur la partie 24 par soudage. Cette partie annulaire 25 présente un cran de glace 26 dans lequel est fixé un verre saphir 27 avec intercale- ment d'un joint en matière plastique 28. Comme on le voit au dessin, la partie annulaire 25 déborde vers l'intérieur sous le joint 28 et sous la périphérie d'un cadran 28 fixé sur un mouvement 29. Ce mouvement est porté lui-même par un cercle d'agrandissement en matière plastique 30 qui est engagé à l'intérieur de l'élément intermédiaire 21.In this second embodiment, an intermediate element 21 forms a single piece with a radial extension 22 which is pierced with a passage 23 for the movement control rod. The intermediate element 21 here comprises a first annular part 24 which is made of steel like the tubular part 22 and a prominent annular part 25 which is made of gold and fixed to the part 24 by welding. This annular part 25 has a notch of crystal 26 in which is fixed a sapphire crystal 27 with the interposition of a plastic seal 28. As can be seen in the drawing, the annular part 25 projects inwards under the seal 28 and under the periphery of a dial 28 fixed to a movement 29. This movement is itself carried by a plastic enlargement circle 30 which is engaged inside the intermediate element 21.

La boîte de montre comporte en outre une lunette 31 qui peut être en acier par exemple. Cette lunette présente un décrochement interne 32 qui est engagé sur un épaulement supérieur de l'élément intermédiaire 21. Elle est fixée à un fond 33 dont la forme est la même que celle du fond 3 de la première forme d'exécution. Une garniture d'étanchéité 34 est pincée entre un épaulement périphérique du fond 33 et la face plane inférieure de l'élément 21.The watch case further includes a bezel 31 which may be made of steel for example. This bezel has an internal recess 32 which is engaged on an upper shoulder of the intermediate element 21. It is fixed to a bottom 33 whose shape is the same as that of the bottom 3 of the first embodiment. A seal 34 is pinched between a peripheral shoulder of the bottom 33 and the lower flat face of the element 21.

La fig. 6 montre la structure de la boîte décrite dans une coupe selon l'axe 6 h-12 h. Comme cette boîte est de forme générale rectangulaire, avec côtés incurvés, on voit que les parties annulaires 24 et 25 de l'élément intermédiaire 21 sont situées à une distance du mouvement 29 qui est plus grande aux extrémités de la boîte que dans la coupe 3 h-9 h. Le cercle d'agrandissement 30 est donc plus large dans cette coupe qu'à la fig. 5.Fig. 6 shows the structure of the box described in a section along the axis 6 am to 12 pm. As this box is of generally rectangular shape, with curved sides, it can be seen that the annular parts 24 and 25 of the intermediate element 21 are located at a distance from the movement 29 which is greater at the ends of the box than in section 3 9 a.m. The enlargement circle 30 is therefore wider in this section than in FIG. 5.

On voit également à la fig. 6 que des cornes 35 sont formées d'une pièce avec la lunette 31 et que le long de ses petits côtés, cette dernière présente une nervure de telle sorte que son épaisseur est plus grande que sur ses grands côtés. Cette nervure est engagée sur un décrochement correspondant du fond. Ainsi, le long des grands côtés de la boîte (fig. 5) la lunette 31 et le fond 33 sont en contact le long d'un plan de jonction 36 qui se trouve au niveau de l'axe du passage radial 23, c'est-à-dire à un niveau moyen, situé à mi-hauteur entre les faces supérieure et inférieure de l'élément 21. En revanche, le long des petits côtés de la lunette 31, le plan de jonction 37 entre le fond 33 et la lunette 31 se trouve presque au niveau de la face inférieure 38 de l'élément 21.We also see in fig. 6 that horns 35 are formed in one piece with the bezel 31 and that along its short sides, the latter has a rib so that its thickness is greater than on its long sides. This rib is engaged on a corresponding recess of the bottom. Thus, along the long sides of the box (fig. 5) the bezel 31 and the bottom 33 are in contact along a junction plane 36 which is located at the axis of the radial passage 23, c ' that is to say at a medium level, located halfway between the upper and lower faces of the element 21. On the other hand, along the short sides of the bezel 31, the junction plane 37 between the bottom 33 and the bezel 31 is almost at the level of the lower face 38 of the element 21.

Du fait que le plan de jonction 37 est déporté en direction du fond aux deux extrémités de la boîte, la fixation du fond 33 à la lunette 31 peut être réalisée au moyen de quatre vis 39 qui sont vissées dans des trous taraudés 40 situés dans les angles de la lunette. L'épaisseur de la lunette est en effet assez grande à ces endroits pour que des trous borgnes taraudés offrent une bonne prise aux vis. Les têtes 39a des vis de fixation s'appuient sur des épaulements internes 41 ménagés à l'extrémité de passages 42 percés dans le fond 33.Because the junction plane 37 is offset towards the bottom at the two ends of the box, the fixing of the bottom 33 to the bezel 31 can be carried out by means of four screws 39 which are screwed into tapped holes 40 located in the bezel angles. The thickness of the bezel is indeed large enough in these places for tapped blind holes to provide good grip for the screws. The heads 39a of the fixing screws are supported on internal shoulders 41 formed at the end of passages 42 drilled in the bottom 33.

Cette seconde forme d'exécution permet de réaliser des modèles de boîtes variés grâce à un choix judicieux des différents matériaux des pièces décrites. Pour des raisons de fabrication, et afin de permettre de réaliser des boîtes d'épaisseur minimale, l'élément intermédiaire doit nécessairement être en acier et formé d'une pièce avec le prolongement radial. Toutefois, la construction de la fig. 6 permet de réaliser une boîte dans laquelle la partie apparente 25 de l'élément intermédiaire est en or, tandis que la lunette 31 est en acier. La lunette assure donc la fiabilité de la fixation du fond au moyen des vis 39 et forme un élément décoratif grâce au contraste des matériaux avec la partie annulaire 25. La pièce peut être parfaitement étanche grâce aux joints 28 et 34. L'engagement d'un verre saphir dans un cran comme le cran 26 permet des exécutions dans lesquelles le verre 27 est d'épaisseur réduite. On utilise actuellement des verres saphir d'une épaisseur de 70/100 par exemple ou même moins.This second embodiment makes it possible to produce various box models thanks to a judicious choice of the different materials of the parts described. For manufacturing reasons, and in order to allow boxes of minimum thickness to be produced, the intermediate element must necessarily be made of steel and formed in one piece with the radial extension. However, the construction of FIG. 6 makes it possible to produce a box in which the visible part 25 of the intermediate element is made of gold, while the bezel 31 is made of steel. The bezel therefore ensures the reliability of the fixing of the base by means of the screws 39 and forms a decorative element thanks to the contrast of the materials with the annular part 25. The part can be perfectly sealed thanks to the seals 28 and 34. The engagement of a sapphire crystal in a notch like the notch 26 allows executions in which the glass 27 is of reduced thickness. Sapphire crystals are currently used with a thickness of 70/100 for example or even less.

La construction décrite ci-dessus réunit de façon surprenante toute une série d'avantages qui en découlent de façon indépendante.The construction described above surprisingly brings together a whole series of advantages which flow therefrom independently.

Esthétique -. Les pièces visibles de la boîte, c'est-à-dire la lunette et le fond, sont de forme simple, de sorte que leur état de surface final peut être donné par des moyens rationnels. Grâce au fait que les deux pièces sont séparées par un plan de jonction qui se trouve à mi-hauteur de la boîte, on peut, par exemple, si l'on donne un état de surface final différent à la lunette et au fond, réaliser une boîte dont l'apparence ultra-mince est très frappante.Aesthetics -. The visible parts of the box, that is to say the bezel and the back, are simple in shape, so that their final surface condition can be given by rational means. Thanks to the fact that the two parts are separated by a junction plane which is halfway up the box, we can, for example, if we give a different final surface finish to the bezel and to the bottom, realize a box whose ultra-thin appearance is very striking.

On notera que l'on obtient une réduction de hauteur particulièrement importante, tout en assurant les autres caractéristiques visées, en réalisant la pièce intermédiaire en une pièce avec son prolongement radial. En effet, la distance entre chacune des génératrices supérieure et inférieure du passage cylindrique 11 a et les épaulements supérieur et inférieur de la pièce 11, en contact avec les garnitures 15 et 16, peut être réduite à une valeur beaucoup plus faible que dans le cas où, selon la technique usuelle, on perce un trou radial dans la pièce intermédiaire et on chasse dans ce trou un tube rapporté.It will be noted that a particularly significant reduction in height is obtained, while ensuring the other characteristics targeted, by producing the intermediate piece in one piece with its radial extension. Indeed, the distance between each of the upper and lower generatrices of the cylindrical passage 11a and the upper and lower shoulders of the part 11, in contact with the linings 15 and 16, can be reduced to a much smaller value than in the case where, according to the usual technique, a radial hole is drilled in the intermediate piece and a built-in tube is driven into this hole.

En ce qui concerne les problèmes de fabrication, la pièce intermédiaire 11 ne nécessite pas d'opération de finition du même genre que celles que nécessitent des pièces qui sont apparentes dans la boîte terminée. Ainsi, par exemple, il n'est pas nécessaire de polir les surfaces de cette pièce, de sorte que les opérations d'usinage suffisent à lui donner son état de surface final. On peut ainsi garantir la précision de cette pièce, ce qui contribue à permettre des réalisations de hauteur minimale, tout en garantissant l'esthétique de la boîte et la fiabilité.Regarding manufacturing problems, the intermediate piece 11 does not require finishing operations of the same kind as those required by parts which are visible in the finished box. Thus, for example, it is not necessary to polish the surfaces of this part, so that the machining operations are sufficient to give it its final surface state. We can thus guarantee the precision of this piece, which helps to allow minimum height achievements, while guaranteeing the aesthetics of the box and reliability.

Simplicité d'emboîtage - Comme l'emboîtage s'effectue de façon analogue à ce que l'on connaissait avec les boîtes trois pièces classiques, de nombreuses difficultés sont évitées. En particulier, il n'est pas nécessaire de prévoir un système à tige brisée, comme dans la plupàrt des monocoques. Le mouvement est fixé au cercle 11, après quoi la tige est mise en place à travers le tube 17.Simplicity of fitting - As the fitting is carried out in a similar way to what we knew with the classic three-piece boxes, many difficulties are avoided. In particular, it is not necessary to provide a broken rod system, as in most monohulls. The movement is fixed to the circle 11, after which the rod is placed through the tube 17.

Etanchéité - Les deux garnitures 15 et 16 ainsi que le système d'étanchéité de la tige ou de la couronne par rapport au tube 17 et la fixation du verre à la lunette assurent l'étanchéité complète de l'enceinte qui contient le mouvement.Sealing - The two seals 15 and 16 as well as the stem or crown sealing system relative to the tube 17 and the fixing of the glass to the bezel ensure the complete sealing of the enclosure which contains the movement.

Choix des matériaux - Finalement, la construction décrite se prête à des exécutions pratiques très variées suivant les matériaux que l'on emploie pour les différentes pièces, ces matériaux pouvant être choisis selon les propriétés que l'on désire conférer à la boîte dans une très large gamme de matières.Choice of materials - Finally, the construction described lends itself to very varied practical executions according to the materials that are used for the different parts, these materials being able to be chosen according to the properties which one wishes to confer on the box in a very wide range of materials.

L'élément intermédiaire sera réalisé de préférence en acier inoxydable. Toutefois, des exécutions en matière plastique moulée, notamment en utilisant une matière plastique rigide, supportant une mise en forme de haute précision seront également possibles.The intermediate element will preferably be made of stainless steel. However, executions in molded plastic material, in particular using a rigid plastic material, supporting high precision shaping will also be possible.

Dans d'autres variantes d'exécution, les moyens de fixation de la lunette au fond pourraient être différents de ce qui est représenté au dessin. N'importe quel moyen connu tel que clavettes, vis dirigées dans le sens axial, cran, le cas échéant fond vissé classique, peuvent être utilisés.In other alternative embodiments, the means for fixing the bezel to the bottom could be different from what is shown in the drawing. Any known means such as keys, screws directed in the axial direction, notch, if necessary conventional screwed bottom, can be used.

Dans les deux formes d'exécution décrites, au lieu que le verre soit fixé au moyen d'un joint d'étanchéité qui l'entoure dans un cran de glace de la lunette ou de l'élément intermédiaire, il pourrait aussi, en variante, être pressé contre une garniture d'étanchéité supportée par l'élément intermédiaire, grâce à un rebord interne de la lunette s'appliquant par exemple sur un biseau périphérique du verre.In the two embodiments described, instead of the glass being fixed by means of a seal which surrounds it in a notch of ice in the telescope or the intermediate element, it could also, as a variant , be pressed against a seal supported by the intermediate element, thanks to an internal rim of the bezel applying for example on a peripheral bevel of the glass.
