Description

La présente invention concerne une montre ayant une boíte qui contient un mouvement d'horlogerie électronique et une batterie électrique comprenant au moins une pile ou au moins un accumulateur, la boíte ayant une ouverture inférieure circulaire qui permet d'introduire et d'extraire la batterie et qui est obturée de manière étanche par un couvercle amovible pourvu de moyens de fixation à baïonnette, le couvercle comportant une plaque, laquelle recouvre un logement pour la batterie et forme au moins une partie du fond de la boíte, et une partie annulaire sensiblement cylindrique qui s'étend perpendiculairement à ladite plaque et s'emboíte dans ladite ouverture, ladite partie annulaire portant au moins deux verrous faisant partie des moyens de fixation à baïonnette.The present invention relates to a watch having a case which contains a electronic clock movement and an electric battery comprising at least a battery or at least an accumulator, the box having a lower opening circular which allows to insert and extract the battery and which is closed so waterproof by a removable cover provided with bayonet fixing means, the cover comprising a plate, which covers a housing for the battery and forms at least part of the bottom of the box, and an annular part substantially cylindrical which extends perpendicular to said plate and fits into said opening, said annular part carrying at least two latches forming part of the bayonet fixing means.

Le couvercle amovible qui obture la trappe donnant accès à la batterie peut soit constituer lui-même le fond de la boíte de montre, soit obturer l'ouverture ménagée dans un fond fixé lui-même à la carrure de la boíte ou fait d'une seule pièce avec cette carrure.The removable cover that closes the hatch giving access to the battery can either constitute the bottom of the watch case itself, or close the opening formed in a bottom itself fixed to the middle of the box or made in one piece with this build.

Par l'expression "batterie électrique", on entend désigner ici une source d'énergie électrique qui peut comprendre une ou plusieurs piles à usage unique, ou un ou plusieurs accumulateurs rechargeables.By the expression "electric battery", we mean here a source electrical energy which may include one or more single-use batteries, or one or more rechargeable batteries.

L'invention s'applique particulièrement, mais pas exclusivement, à des montres électroniques comportant un ou plusieurs dispositifs additionnels qui consomment de l'énergie électrique, tels que par exemple un dispositif de communication par transmission radio, optique ou acoustique, un dispositif de mesure utilisant un capteur de pression ou autre, un dispositif de navigation, une caméra électronique, un agenda électronique, etc. Dans bien des cas, la consommation d'énergie de ces dispositifs additionnels nécessite d'inclure dans la montre une batterie électrique assez grosse, comprenant soit plusieurs piles ou accumulateurs, soit une pile ou un accumulateur de grande taille. L'ouverture nécessaire dans le fond de la boíte pour donner accès à cette batterie peut alors devenir très grande et s'étendre sur la majorité, voire la totalité de la surface du fond. Lorsque le couvercle amovible obturant cette ouverture est fixé par un système à baïonnette, l'encombrement des éléments de ce système et des organes d'étanchéité associés peut poser des problèmes.The invention applies particularly, but not exclusively, to watches electronic comprising one or more additional devices which consume electrical energy, such as for example a communication device by radio, optical or acoustic transmission, a measuring device using a sensor pressure or other, a navigation device, an electronic camera, an agenda electronics, etc. In many cases, the energy consumption of these devices additional need to include in the watch a fairly large electric battery, comprising either several batteries or accumulators, or a battery or accumulator large size. The opening necessary in the bottom of the box to give access to this battery can then become very large and extend over the majority, even the entire bottom surface. When the removable cover closing this opening is fixed by a bayonet system, the dimensions of the elements of this system and associated sealing members can cause problems.

La demande de brevet EP 272 515 décrit une montre-bracelet du genre indiqué en préambule ci-dessus et ayant à l'arrière un grand couvercle pour donner accès à la batterie électrique. Afin de permettre une réduction de l'épaisseur de la montre, l'ouverture circulaire du fond de la boíte a un diamètre sensiblement plus grand que le diamètre du cercle circonscrit à l'ensemble formé par le mouvement d'horlogerie et la batterie. Les moyens de fixation à baïonnette sont disposés en dehors de ce cercle, à un niveau situé au-dessus de la face inférieure du mouvement. La partie annulaire cylindrique du couvercle sert à raidir celui-ci et à porter à son sommet les verrous du dispositif de fixation à baïonnette, qui sont dirigés vers l'extérieur pour pouvoir s'accrocher à des rebords intérieurs de la carrure de la boíte. L'étanchéité autour de l'ouverture est assurée de manière classique, au moyen d'un joint torique disposé dans une gorge de la face inférieure de la carrure et comprimé axialement par le couvercle.Patent application EP 272 515 describes a wristwatch of the kind indicated in the preamble above and having at the rear a large cover to give access to the electric heater. In order to allow a reduction in the thickness of the shows, the circular opening at the bottom of the box has a significantly larger diameter large that the diameter of the circle circumscribed to the assembly formed by the movement clock and battery. The bayonet fixing means are arranged in outside this circle, at a level above the underside of the movement. The cylindrical annular part of the cover serves to stiffen the latter and to bring to its top the latches of the bayonet fixing device, which are directed towards the outside to be able to hang on the inside edges of the middle part of the box. Sealing around the opening is ensured in a conventional manner, by means of a O-ring placed in a groove on the underside of the middle part and compressed axially by the cover.

Lorsque la batterie électrique de la montre doit avoir une taille relativement grande en plan, cette construction présente l'inconvénient de nécessiter une ouverture bien plus large, afin de laisser passer les verrous du couvercle entre le pourtour de l'ouverture et le cercle circonscrit à la batterie. De plus, étant donné que la garniture d'étanchéité doit avoir un plus grand diamètre que l'ouverture, le diamètre extérieur du couvercle est encore accru. La grande taille de la batterie conduit donc à une boíte de montre très large. Un autre inconvénient est que si l'utilisateur n'a pas tourné le couvercle bien à fond pour le fixer, l'étanchéité n'est pas garantie puisque la compression axiale de la garniture d'étanchéité risque d'être insuffisante. Il faut que le couvercle comprime assez fortement la garniture d'étanchéité, ce qui implique des efforts importants sur les verrous de la fixation à baïonnette.When the watch's electric battery must be relatively large large in plan, this construction has the disadvantage of requiring an opening much wider, in order to allow the cover latches to pass between the periphery of the opening and the circle circumscribed to the battery. In addition, since the trim sealing must have a larger diameter than the opening, the outside diameter of the cover is further increased. The large size of the battery therefore leads to a box of shows very wide. Another disadvantage is that if the user has not turned the cover securely to fix it, tightness is not guaranteed since the axial compression of the seal may be insufficient. The cover compresses the packing quite strongly, which involves significant efforts on the locks of the bayonet attachment.

La présente invention a pour objet une montre agencée de façon à éviter dans une large mesure les inconvénients susmentionnés, notamment afin de pouvoir limiter la taille du couvercle par rapport au cercle circonscrit à la batterie lorsque celle-ci est particulièrement encombrante, par exemple lorsqu'elle comprend plusieurs piles ou accumulateurs.The present invention relates to a watch arranged so as to avoid in to a large extent the aforementioned drawbacks, particularly in order to be able to limit the size of the cover in relation to the circle circumscribed to the battery when the latter is particularly bulky, for example when it comprises several batteries or Accumulators.

A cet effet, il est prévu une montre du genre indiqué en préambule, dans laquelle lesdits verrous du couvercle s'étendent vers l'intérieur de la partie annulaire sensiblement cylindrique du couvercle et s'accrochent à des épaulements d'au moins un élément fixe monté dans la boíte, lesdits épaulements se trouvant à l'intérieur de ladite partie annulaire quand le couvercle est fixé à la boíte.To this end, a watch of the kind indicated in the preamble, in which said cover latches extend towards the inside of the annular part substantially cylindrical of the cover and cling to shoulders of at least a fixed element mounted in the box, said shoulders being inside said annular part when the cover is fixed to the box.

Cette idée simple conduit à un gain substantiel sur le diamètre de l'ouverture et la dimension minimale en plan du couvercle, particulièrement lorsque la batterie n'est pas circulaire, parce que l'espace occupé à l'intérieur de la boíte par les verrous du système à baïonnette, qui ne parcourent qu'un arc de longueur restreinte autour de la batterie, peut être situé dans des zones libres entre la batterie et le cercle circonscrit à celle-ci. Ainsi, l'intervalle radial minimal entre ce cercle et le pourtour de l'ouverture est réduit parce que dicté seulement par l'épaisseur de la partie annulaire cylindrique du couvercle et le petit jeu nécessaire autour de celle-ci, mais pas par la taille des verrous.This simple idea leads to a substantial gain on the diameter of the opening and the minimum dimension of the cover in plan, particularly when the battery is not not circular, because the space occupied inside the box by the latches of the bayonet system, which travel only a short arc around the battery, can be located in free areas between the battery and the circle circumscribed it. Thus, the minimum radial interval between this circle and the periphery of the opening is reduced because dictated only by the thickness of the cylindrical annular part of the cover and the small clearance required around it, but not by the size of the locks.

De plus, la disposition des verrous vers l'intérieur de la partie annulaire du couvercle permet avantageusement de disposer la garniture d'étanchéité autour de cette partie annulaire, pour que la garniture soit pressée radialement contre une surface circulaire formant le pourtour de ladite ouverture, notamment une surface sensiblement cylindrique. L'ouverture peut avoir en outre une entrée évasée pour assurer une compression radiale de la garniture d'étanchéité lors de la mise en place du couvercle. Cette disposition de la garniture d'étanchéité prend très peu de place en direction radiale et permet donc de réduire notablement la largeur du couvercle par rapport à l'art antérieur cité plus haut. Grâce à la compression radiale de la garniture, l'étanchéité est garantie même si le couvercle n'a pas été tourné à fond lorsqu'on l'a mis en place, et par ailleurs la compression de la garniture n'induit pratiquement pas d'efforts supplémentaires sur les verrous.In addition, the arrangement of the locks towards the inside of the annular part of the cover advantageously allows the packing to be arranged around this annular part, so that the lining is pressed radially against a circular surface forming the periphery of said opening, in particular a surface substantially cylindrical. The opening may further have a flared entry for ensure radial compression of the seal during installation of the cover. This arrangement of the packing takes up very little space in radial direction and therefore makes it possible to significantly reduce the width of the cover by compared to the prior art cited above. Thanks to the radial compression of the lining, tightness is guaranteed even if the cover has not been turned fully when it has been in place, and moreover compression of the lining practically does not induce extra effort on locks.

De préférence, des moyens de prise sont disposés sur une partie périphérique du couvercle de façon à permettre à un utilisateur de manoeuvrer manuellement le couvercle sans outil spécifique.Preferably, gripping means are arranged on a peripheral part of the cover so as to allow a user to manually operate the cover without special tool.

La montre-bracelet peut être mise autour du poignet au moyen de deux brins de bracelet 10 et 11 attachés à la carrure de la boíte 2 et réunis par un fermoir de type connu.Figure 1 shows in perspective a wristwatch 1 comprising a box 2 of non-circular shape, closed above by a glass 6 arranged above a dial for an analog display of the time using hands 4 and 5 driven by an electronic watch movement. The dial can also have a window for a digital or alphanumeric display 7. One or several control members 8 are arranged on the box. The wristwatch can be put around the wrist by means of two strands of bracelet 10 and 11 attached to the middle of the box 2 and joined by a clasp of known type.

Dans la figure 2, on voit plus particulièrement le dessous de la boíte de montre 2. Dans le présent exemple, celle-ci est faite d'une construction monobloc comprenant une carrure 13 et un fond 14, dans lequel est ménagé une ouverture circulaire 15 servant de trappe d'accès à la batterie électrique (non représentée dans cette figure). La paroi périphérique de l'ouverture 15 comporte une surface circulaire 16 sensiblement cylindrique. Le fond-carrure de la boíte de montre 2 est équipé d'organes d'attache 17 et 18 permettant de le rattacher aux brins 10 et 11 du bracelet.In Figure 2, we can see more particularly the underside of the watch case 2. In the present example, this is made of a one-piece construction comprising a middle part 13 and a base 14, in which is formed a circular opening 15 serving as an access hatch to the electric heater (not shown in this figure). The peripheral wall of the opening 15 has a circular surface 16 substantially cylindrical. The case back of the watch case 2 is equipped attachment members 17 and 18 allowing it to be attached to the strands 10 and 11 of the bracelet.

Normalement, l'ouverture 15 est obturée de manière étanche par un couvercle circulaire amovible 20 qui, dans la vue de la figure 2, a été enlevé pour laisser voir un support de batterie 22 monté de manière fixe à l'intérieur de la boíte 2. Le couvercle 20, quand il est mis en place dans l'ouverture 15, se fixe au support 22 par un dispositif de fixation du type à baïonnette, qu'on décrira en détail plus loin. Dans cet exemple, le support 22 comporte deux logements circulaires 23 et 24 pour deux piles formant ensemble la batterie électrique destinée à alimenter les circuits contenus dans la montre. Dans cet exemple, la boíte et le couvercle sont de préférence métalliques, mais d'autres matériaux sont envisageables.Normally, the opening 15 is sealed off by a cover removable circular 20 which, in the view of FIG. 2, has been removed to reveal a battery holder 22 fixedly mounted inside the box 2. The cover 20, when it is placed in the opening 15, is fixed to the support 22 by a fixing device of the bayonet type, which will be described in detail below. In this example, the support 22 has two circular housings 23 and 24 for two batteries together forming the electric battery intended to supply the contained circuits in the watch. In this example, the box and the lid are preferably metallic, but other materials are possible.

Les figures 3 et 6 montrent plus en détail la structure interne de la montre et les principaux composants de celle-ci. On décrira les détails du couvercle 20 en référence aux figures 4 et 5.Figures 3 and 6 show in more detail the internal structure of the watch and the main components of it. The details of the cover 20 will be described in reference to Figures 4 and 5.

Dans la figure 3, on voit que la glace 6 de la montre est portée par une lunette en deux pièces 26 et 27, montée sur le sommet de la carrure 13 avec une garniture d'étanchéité 28. On trouve sous le cadran 29 de la montre l'affichage à cristaux liquides 7 et un mouvement d'horlogerie électronique 30 comprenant notamment un résonateur à quartz 31 et un moteur électrique 32 qui actionne les aiguilles 4 et 5. Ces éléments sont montés sur une carte à circuits imprimés 33 qui est fixée dans la boíte par des moyens classiques, comprenant notamment une platine 34 en matière plastique qui supporte le cadran 29.In Figure 3, we see that the crystal 6 of the watch is carried by a bezel in two parts 26 and 27, mounted on the top of the middle 13 with a trim 28. There is a crystal display under the dial 29 of the watch. liquids 7 and an electronic clock movement 30 comprising in particular a quartz resonator 31 and an electric motor 32 which actuates hands 4 and 5. These elements are mounted on a printed circuit board 33 which is fixed in the box by conventional means, including in particular a plate 34 in material plastic which supports the dial 29.

Au-dessous de la carte 33 se trouve un dispositif électronique additionnel 36 monté sur une carte à circuits imprimés 37. Ce dispositif additionnel peut être de l'un des types mentionnés plus haut et comporter, par exemple, un ou plusieurs circuits intégrés 38 et des mémoires 39. Il est alimenté en énergie électrique, tout comme les composants montés sur la carte 33, par la batterie électrique formée par les deux piles 41 et 42 logées dans le support 22 et connectées en série à l'aide de lames métalliques intégrées à ce support, lequel est en matière synthétique isolante. Afin de simplifier le dessin, les connexions électriques entre les piles 41 et 42, le support 22, la carte 37 et la carte 33 ne sont pas représentés. Bien entendu, on pourrait aussi prévoir des alimentations séparées, l'une des piles alimentant les composants montés sur la carte 33 et l'autre les composants montés sur la carte 37.Below the card 33 is an additional electronic device 36 mounted on a printed circuit board 37. This additional device can be of one of the types mentioned above and include, for example, one or more circuits integrated 38 and memories 39. It is supplied with electrical energy, just like the components mounted on the board 33, by the electric battery formed by the two batteries 41 and 42 housed in the support 22 and connected in series using blades metal integrated into this support, which is made of insulating synthetic material. In order to simplify the drawing, the electrical connections between the batteries 41 and 42, the support 22, card 37 and card 33 are not shown. Of course, we could also provide separate power supplies, one of the batteries supplying the mounted components on card 33 and the other the components mounted on card 37.

Le couvercle amovible 20 comporte une plaque circulaire 44 qui recouvre toute l'ouverture 15 du fond de la boíte et qui a une partie périphérique 45 plus épaisse que sa partie centrale. Cette partie périphérique forme un rebord qui s'applique contre la face inférieure plane 46 du fond 14 de la boíte, quand le couvercle 20 est en position de fermeture. Deux encoches 47 sont ménagées dans la face extérieure de la partie périphérique 45 pour permettre à un utilisateur de faire tourner manuellement le couvercle au moyen de ses ongles ou d'un objet courant par exemple une clé ou une boucle du fermoir du bracelet de la montre. Selon une variante, un moletage pourrait être prévu comme moyen de prise manuelle sur la partie périphérique du couvercle. Sur la face intérieure du couvercle 22, un transducteur électro-acoustique 48, composé de préférence d'éléments piézo-électriques, est collé à la partie centrale de la plaque 44 afin de la faire vibrer, pour transmettre un signal acoustique et/ou tactile au porteur de la montre. Un bourrelet 49 est prévu autour du transducteur 48 pour améliorer le régime vibratoire de la plaque 44.The removable cover 20 comprises a circular plate 44 which covers all the opening 15 at the bottom of the box and which has a peripheral part 45 thicker than its central part. This peripheral part forms a rim which is applied against the flat underside 46 of the bottom 14 of the box, when the cover 20 is in position closing. Two notches 47 are formed in the outer face of the part device 45 to allow a user to manually rotate the cover by means of his nails or a common object, for example a key or a buckle of the watch strap clasp. Alternatively, knurling could be provided as a means of manual grip on the peripheral part of the cover. On the inner face of the cover 22, an electro-acoustic transducer 48, preferably composed of piezoelectric elements, is glued to the central part of the plate 44 in order to make it vibrate, to transmit an acoustic and / or tactile signal to the wearer of the watch. A bead 49 is provided around the transducer 48 for improve the vibration regime of the plate 44.

Au-dessus de sa partie périphérique 45, le couvercle 22 comporte une partie annulaire 50 sensiblement cylindrique dont la face extérieure présente une gorge 51 pour recevoir une garniture annulaire d'étanchéité 52 formée dans ce cas par un joint torique en élastomère. Afin de réduire la friction, ce joint peut être fait d'un matériau autolubrifiant. La gorge 51 est fermée vers le haut par une rondelle métallique plate 54 qui est soudée en des points 53 sur le sommet de la partie annulaire 50 de couvercle. Le diamètre extérieure de cette rondelle est sensiblement égal à celui de la face extérieure cylindrique 55 de la partie annulaire 50. La rondelle 54 comporte deux parties saillantes radialement vers l'intérieur, qui sont diamétralement opposées et forment deux verrous 56 du dispositif de fixation à baïonnette du couvercle. Dans le cas présent, les deux verrous 56 sont plats et situés dans le même plan que le reste de la rondelle 54, mais dans d'autre modes de réalisation ils pourraient être inclinés ou pliés en Z, selon les besoins. D'autre part, le nombre des verrous 56 pourrait évidemment être supérieur à deux.Above its peripheral part 45, the cover 22 includes a part annular 50 substantially cylindrical, the outer face of which has a groove 51 to receive an annular seal 52 formed in this case by a seal elastomer ring. To reduce friction, this joint can be made of a material self-lubricating. The groove 51 is closed upwards by a flat metal washer 54 which is welded at points 53 on the top of the annular part 50 of lid. The outer diameter of this washer is substantially equal to that of the cylindrical outer face 55 of the annular part 50. The washer 54 has two radially inward projecting parts which are diametrically opposite and form two locks 56 of the bayonet fixing device for the cover. In the case present, the two locks 56 are flat and located in the same plane as the rest of washer 54, but in other embodiments they could be tilted or Z-folded, as required. On the other hand, the number of locks 56 could obviously be greater than two.

La figure 6 montre le support de batterie 22 vu de dessous. Il s'agit d'une pièce moulée en matière synthétique rigide et isolante, qui est maintenue en position à l'intérieur de la boíte de montre par appui contre le fond 14 et à l'aide de pieds 60 et 61. On voit en particulier dans la figure 3 que chaque pied 61 s'emboíte dans un trou borgne 62 du fond de la boíte. On voit également que ce pied est solidaire d'une partie saillante 63 du support, qui maintient par pincement une des lames de contact 64 qui assurent la connexion entre la batterie et les circuits électriques de la montre. D'autres lames de ce genre sont logées dans des évidements appropriés du support 22, notamment ceux qui portent les références 65 à 67 dans la figure 6. L'évidement 67 contient une ou plusieurs lames reliant le transducteur 48 à son circuit de commande.Figure 6 shows the battery holder 22 seen from below. This is a room molded in rigid and insulating synthetic material, which is held in position at the inside of the watch case by pressing against the bottom 14 and using feet 60 and 61. We see in particular in Figure 3 that each foot 61 fits into a hole blind 62 from the bottom of the box. We also see that this foot is integral with a protruding part 63 of the support, which clamps one of the contact blades 64 which provide the connection between the battery and the electrical circuits of the watch. Other blades of this kind are housed in suitable recesses of the support 22, in particular those which bear the references 65 to 67 in FIG. 6. The recess 67 contains one or more blades connecting the transducer 48 to its circuit ordered.

Le support 22 sert aussi à retenir en place le couvercle amovible 20 et il comporte à cet effet les éléments fixes du dispositif de fixation à baïonnette. Ces éléments comprennent deux épaulements 70 et 71 situés sur la face supérieure de deux rebords 72 et 73 du support 22 qui sont dirigés vers l'extérieur. Les épaulements 70 et 71 présentent en plan une forme en arc de cercle de faible longueur et ils peuvent être légèrement inclinés longitudinalement afin de tirer le couvercle vers l'intérieur de la boíte. Au-dessus de ces épaulements se trouvent des encoches respectives 74 et 75 dans lesquelles peuvent passer les verrous 56 du couvercle 20.The support 22 also serves to hold in place the removable cover 20 and it for this purpose comprises the fixed elements of the bayonet fixing device. These elements include two shoulders 70 and 71 located on the upper face of two edges 72 and 73 of the support 22 which are directed outwards. The shoulders 70 and 71 have in plan a short arc shape and they can be tilted slightly longitudinally to pull the cover towards inside the box. Above these shoulders are notches 74 and 75 respectively through which the locks 56 of the cover 20 can pass.

Dans la figure 6, on remarque que les éléments fixes 72 à 75 du dispositif de fixation à baïonnette, ainsi que des espaces libres 76 et 77 permettant le passage des verrous 56 en direction axiale lorsque l'on introduit le couvercle 20 dans la boíte, sont tous situés à des endroits qui ne sont pas occupés par la batterie formée par les piles prenant place dans les logements 23 et 24. Si l'on se réfère à la figure 2, on observe que ces éléments se situent tout de même à l'intérieur d'un cercle 80 circonscrit à la batterie lorsque celle-ci est vue en plan. En pratique, on profite du fait que l'ensemble de la batterie n'a pas une forme circulaire et laisse donc subsister des zones inoccupées à l'intérieur du cercle circonscrit 80. Le même avantage pourrait être mis à profit, par exemple, si une unique pile ou un accumulateur constituant la batterie avait une forme carrée ou rectangulaire en plan.In FIG. 6, it is noted that the fixed elements 72 to 75 of the device for bayonet fixing, as well as free spaces 76 and 77 allowing the passage of latches 56 in the axial direction when the cover 20 is introduced into the box, are all located in places which are not occupied by the battery formed by the batteries taking place in the housings 23 and 24. If one refers to figure 2, one observes that these elements are located all the same inside a circle 80 circumscribed with the battery when it is viewed in plan. In practice, we take advantage of the fact that the whole of the battery does not have a circular shape and therefore leaves areas unoccupied inside the circumscribed circle 80. The same advantage could be put to profit, for example, if a single battery or accumulator constituting the battery had a square or rectangular shape in plan.

Il faut noter que la figure 3 ne fait pas voir la largeur maximale de la batterie, puisque le plan de cette coupe est oblique par rapport à celui passant par les centres des deux logements de piles 23 et 24. En fait, chaque pile s'étend jusqu'à une faible distance de la partie annulaire 50 du couvercle.Note that Figure 3 does not show the maximum width of the battery, since the plane of this section is oblique to that passing through the centers of the two battery compartments 23 and 24. In fact, each battery extends to a low distance from the annular part 50 of the cover.

Il en résulte avantageusement que le diamètre de l'ouverture 15 doit être seulement un peu plus grand que celui du cercle circonscrit 80, dans une mesure suffisante pour laisser passer l'épaisseur de I
a partie annulaire cylindrique 50 du couvercle. Comme en outre le bord extérieur du couvercle n'a pas besoin de dépasser de beaucoup le pourtour de l'ouverture 15, cette dernière peut être aussi grande que possible, compte tenu des dimensions du fond 14 de la boíte, et donc donner accès à une batterie de grande taille. It advantageously follows that the diameter of the opening 15 must be only a little larger than that of the circumscribed circle 80, to a sufficient extent to allow the thickness of I
has cylindrical annular part 50 of the cover. As also the outer edge of the cover does not need to go much beyond the periphery of the opening 15, the latter can be as large as possible, given the dimensions of the bottom 14 of the box, and therefore provide access to a large battery.

Le couvercle 20 ainsi agencé assure une excellente étanchéité du fond de la boíte en toutes circonstances. Au moment où on l'introduit en direction axiale dans l'ouverture 15, l'entrée évasée 81 de celle-ci écrase progressivement la garniture en élastomère 52, qui se trouve ensuite comprimée radialement en permanence entre la partie annulaire 50 du couvercle et la surface cylindrique fixe 16 avant même que le couvercle soit complètement enfoncé dans la boíte. Pendant qu'on fait ensuite tourner le couvercle pour engager les verrous 56 sur les épaulements 70 et 71, qui vont tirer le couvercle jusqu'à ce que son bord s'appuie contre la face inférieure 46 du fond, les conditions d'étanchéité ne changent pas et la compression de la garniture 52 n'induit aucun effort sur les verrous 56, ni sur le support 22. Il en va évidemment de même durant l'opération d'ouverture du couvercle.The cover 20 thus arranged ensures excellent sealing of the bottom of the box in all circumstances. When we introduce it in an axial direction in the opening 15, the flared entry 81 of the latter progressively crushes the lining in elastomer 52, which is then permanently compressed radially between the annular part 50 of the cover and the fixed cylindrical surface 16 even before the cover is completely pushed into the box. While we then spin the cover to engage the locks 56 on the shoulders 70 and 71, which will pull the cover until its edge bears against the underside 46 of the bottom, the sealing conditions do not change and compression of the lining 52 does not induce no effort on the locks 56, nor on the support 22. It is obviously the same during the lid opening operation.

La figure 7 représente schématiquement un mode de réalisation d'une montre dans laquelle le couvercle amovible 20 constitue entièrement le fond de la boíte de montre, sa partie périphérique 45 recouvrant la face inférieure 82 de la carrure 13 et allant s'appliquer contre celle-ci sous l'effet du dispositif de fixation à baïonnette du couvercle. Les verrous intérieurs 56 du couvercle s'accrochent à un support fixe quelconque 83 monté à l'intérieur de la boíte, en s'appuyant chacun sur un épaulement 71 d'un rebord 73 du support comme dans l'exemple précédent. Le support 83 est maintenu en butée contre un épaulement 84 de la carrure, par exemple grâce à des brides plates classiques 85 dont chacune est fixée sur une surface inférieure du support par une vis 86 et engagée dans une encoche 87 de la carrure 13. Les brides 85 sont situées de préférence à un autre endroit que les organes d'accrochage 71 et 73 du dispositif de fixation à baïonnette. Le support 83 n'est pas nécessairement un support de batterie, mais pourrait être formé par exemple par une platine d'un mouvement d'horlogerie ou par un container en matière synthétique moulée qui contient un tel mouvement. Il pourrait aussi constituer un cercle d'emboítage supportant le mouvement dans la boíte 2.FIG. 7 schematically represents an embodiment of a watch in which the removable cover 20 completely constitutes the bottom of the box shows, its peripheral part 45 covering the lower face 82 of the middle part 13 and going to be applied against it under the effect of the bayonet fixing device of the lid. The interior locks 56 of the cover hang on a fixed support any 83 mounted inside the box, each leaning on a shoulder 71 of a rim 73 of the support as in the previous example. The support 83 is held in abutment against a shoulder 84 of the middle part, for example thanks to conventional flat flanges 85 each of which is fixed to a surface lower of the support by a screw 86 and engaged in a notch 87 of the middle part 13. The flanges 85 are preferably located somewhere other than the components hooking 71 and 73 of the bayonet fixing device. Support 83 is not necessarily a battery holder, but could be formed for example by a plate from a watch movement or from a plastic container molded which contains such movement. It could also form a circle socket supporting the movement in the box 2.

Dans l'exemple de la figure 7, les éléments 50, 52 et 54 du fond-couvercle 20 sont analogues à ceux de l'exemple des figures 2 à 6, mais ont évidemment un plus grand diamètre. Par contre, les encoches 47 de l'exemple précédent sont remplacées par un moletage 88 de la face inférieure de la partie périphérique 45, pour servir de moyen de prise manuelle permettant à l'utilisateur d'ouvrir et fermer le couvercle sans aucun outil.In the example of FIG. 7, the elements 50, 52 and 54 of the bottom cover 20 are similar to those of the example in Figures 2 to 6, but obviously have a plus large diameter. On the other hand, the notches 47 of the previous example are replaced by knurling 88 on the underside of the peripheral part 45, to serve as manual gripping means allowing the user to open and close the cover without no tools.

On notera enfin que les principes des constructions décrites ci-dessus peuvent s'appliquer aussi bien à des boítes de montre métalliques qu'à des boítes faites d'autres matériaux, notamment des matériaux céramiques ou synthétiques.Finally, it should be noted that the principles of the constructions described above can apply both to metal watch cases and to made cases other materials, especially ceramic or synthetic materials.
