Abstract

A wrist-watch case includes a back that is screwed onto a spacer ring and an assembly of two caps and a crystal that forms one piece attached to the case-band by screws fastened into the caps from the underside of the case-band. This construction makes it possible to integrate a bracelet perfectly with the case through the caps, each cap forming an end link having the same appearance as the articulated links of the bracelet and adjoining the beveled edge of the crystal. This construction is particularly well adapted to the use of caps and links made entirely of hard metal.

Description

L'invention est relative à une boîte de montre-bracelet comprenant une carrure, une glace découpée pour se trouver bord à bord avec le pourtour extérieur de la face supérieure plane de la carrure, ledit pourtour extérieur situé à 3 heures et à 9 heures coïncidant avec le bord de la boite, un cercle d'agrandissement reposant sur une première battue intérieure de la carrure pour porter le mouvement, et un fond vissé.The invention relates to a wristwatch case comprising a middle part, a crystal cut out to be side by side with the outer periphery of the planar upper face of the middle part, said outer periphery situated at 3 o'clock and 9 o'clock coinciding. with the edge of the case, an enlargement circle resting on a first inner beat of the middle to carry the movement, and a screwed back.

On connaît des boites de montre-bracelet où les tranches de la glace situées à 3 heures et à 9 heures coïncident avec le bord de la boite. Une telle construction est montrée par exemple dans le brevet CH 592 911 où l'on peut voir en figure 3 une glace 3 située bord à bord avec la carrure 2. La glace est engagée à 6 heures et à 12 heures dans deux coulisses parallèles présentées par un élément de la boîte et dans lesquelles elle est maintenue par une garniture d'étanchéité qu'elle comprime et qui prend appui sur sa face intérieure. Cette construction présente plusieurs inconvénients. Celui d'abord de la mise en place de la glace par glissement dans les coulisses : cette opération, outre qu'elle est rendue difficile par la présence de la garniture, peut endommager une décoration qu'il serait souhaitable d'apposer sous la glace. Celui ensuite de présenter deux pièces 8 d'attache de bracelet dont la fabrication est difficile, voire impossible si ces pièces devaient être réalisées en métal dur, et dont le système d'ancrage à la carrure conduit à une configuration très saillante, difficilement intégrable à un bracelet si les pièces en question devaient constituer le maillon terminal dudit bracelet. Celui enfin de ne pas offrir un fond amovible par lequel on pourrait avoir accès pour le changement périodique de la pile dans le cas où l'on a affaire à une montre électronique.Wristwatch boxes are known where the sections of the ice at 3 o'clock and at 9 o'clock coincide with the edge of the box. Such a construction is shown for example in patent CH 592 911 where we can see in FIG. 3 a lens 3 located edge to edge with the middle part 2. The lens is engaged at 6 o'clock and at 12 o'clock in two parallel slides presented by an element of the box and in which it is held by a seal which it compresses and which bears on its inner face. This construction has several drawbacks. First of all, the installation of the glass by sliding it behind the scenes: this operation, apart from being made difficult by the presence of the trim, can damage a decoration which it would be desirable to affix under the glass. . The next step is to present two pieces of strap attachment whose manufacture is difficult, if not impossible if these parts were to be made of hard metal, and whose anchoring system to the middle leads to a very salient configuration, difficult to integrate into a bracelet if the pieces in question were to constitute the end link of said bracelet. Finally, that of not offering a removable bottom through which one could have access for the periodic change of the battery in the case where one is dealing with an electronic watch.

Pour remédier aux inconvénients cités, la boîte de montre objet de la présente invention propose une construction permettant l'intégration parfaite d'un bracelet formé de maillons à la boite proprement dite tout en assurant un montage et un démontage aisés sans précaution particulière. Ce but est atteint grâce aux moyens qui apparaissent dans les revendications.To remedy the drawbacks mentioned, the watch case which is the subject of the present invention provides a construction allowing the perfect integration of a bracelet formed of links into the box itself while ensuring easy assembly and disassembly without particular precautions. This object is achieved by the means which appear in the claims.

L'invention sera comprise maintenant à la lumière de la description qui suit et des dessins qui l'illustrent et qui donnent, à titre d'exemple, une forme d'exécution de ladite invention dans lesquels :

  • La figure 1 est une vue en plan de la boite de montre et du bracelet qui lui est associé selon la présente invention.
  • La figure 2 est une vue en coupe à 6 heures - 12 heures de la boite selon la figure 1, à échelle agrandie.
The invention will now be understood in the light of the following description and the drawings which illustrate it and which give, by way of example, an embodiment of said invention in which:
  • Figure 1 is a plan view of the watch case and the bracelet associated therewith according to the present invention.
  • Figure 2 is a sectional view at 6 o'clock - 12 o'clock of the box according to Figure 1, on an enlarged scale.

La figure 1 est une vue de dessus de la montre selon l'invention. A travers là glace 1 apparaît l'affichage représenté par deux aiguilles 2. Le dessous de la glace est pourvu d'une décoration 3 formant cadre. Cette décoration est réalisée généralement par une métallisation qui cache la face supérieure de la carrure, le joint d'étanchéité et le réhaut. Sur le flanc droit de la montre apparaît un organe 4 qui permet la correction de l'affichage. On s'aperçoit que le bord de la glace coïncide avec le bord de la boite sur les flancs situés à 3 heures et à 9 heures. A 6 heures et à 12 heures, les bords de la glace sont juxtaposés chacun avec un maillon terminal 5 du bracelet 6. La partie supérieure apparente du maillon terminal 5 comprend une partie plane 7 alignée avec le plan de la glace et une partie inclinée 8 vers le dessous de la figure, cette partie inclinée étant équipée par exemple d'un charneron qui l'attache au premier maillon mobile du bracelet 6.Figure 1 is a top view of the watch according to the invention. Through glass 1 appears the display represented by two needles 2. The underside of the glass is provided with a decoration 3 forming a frame. This decoration is generally carried out by a metallization which hides the upper face of the middle part, the seal and the flange. On the right side of the watch appears a member 4 which allows the correction of the display. We notice that the edge of the ice coincides with the edge of the box on the sides located at 3 o'clock and at 9 o'clock. At 6 o'clock and at 12 o'clock, the edges of the glass are juxtaposed each with a terminal link 5 of the bracelet 6. The visible upper part of the terminal link 5 comprises a flat part 7 aligned with the plane of the glass and an inclined part 8 towards the bottom of the figure, this inclined part being equipped for example with a hinge which attaches it to the first movable link of the bracelet 6.

On se référera maintenant à la figure 2 pour bien comprendre comment est exécutée et assemblée la boite de montre selon l'invention. Cette boite comprend une carrure 9 qui comporte deux battues. Une première battue intérieure 10 est destinée à recevoir un cercle d'agrandissement 11 agencé pour recevoir à son tour le mouvement 12 qui est fixé au cercle au moyen de brides non représentées. Une seconde battue extérieure 14 est pratiquée dans la carrure 9. Dans cette battue est engagée et fixée une coiffe 5 qui forme le maillon terminal dont il a déjà été question à propos de la figure 1. Cette coiffe présente les parties plane 7 et inclinée 8 déjà mentionnées et déborde de la carrure pour s'adapter au bracelet proprement dit 6. Un biseau 15 est taillé sur la tranche de la glace 1 et la coiffe 5 est solidarisée à la glace à l'endroit de ce biseau par des moyens appropriés, par exemple par soudage ou par collage.Reference will now be made to FIG. 2 in order to fully understand how the watch case according to the invention is executed and assembled. This box includes a middle 9 which has two battues. A first internal battée 10 is intended to receive an enlargement circle 11 arranged to receive in turn the movement 12 which is fixed to the circle by means of flanges not shown. A second outer battée 14 is formed in the middle part 9. In this battue is engaged and fixed a cap 5 which forms the end link which has already been discussed in connection with FIG. 1. This cap has the flat 7 and inclined 8 parts already mentioned and extends beyond the middle to adapt to the bracelet proper 6. A bevel 15 is cut on the edge of the crystal 1 and the cap 5 is secured to the ice at the location of this bevel by appropriate means, for example by welding or gluing.

La glace 1 et les deux coiffes 5 (dont une seule est représentée au dessin) forment ainsi dans l'exécution selon l'invention un ensemble amovible de prémontage qui peut être assujetti à la boite ou au contraire séparé de celle-ci pour des besoins d'entretien ou de réparation. L'ensemble en question est fixé à la carrure au moyen de vis 16, disposées par paires situées l'une à 6 heures et l'autre à 12 heures. Pour assurer l'étanchéité de la boite, on dispose entre la glace 1 et la face supérieure plane 17 de la carrure une garniture d'étanchéité 18 que la glace comprime quand on serre les vis 16 dont les têtes s'appuient sur le fond de carrure. Ces vis 16 sont directement vissées dans un trou borgne taraudé dans la coiffe. Dans le cas où la coiffe est réalisée en matériau dur, comme cela appa- raitra plus bas, les trous borgnes sont munis de manchons taraudés 23 pour recevoir les vis. Dans l'exécution de la figure 2, on voit encore un réhaut flottant 19 qui maintient le cadran 13 en place. Dans cette exécution, on pratique une échancrure à la fois dans la carrure et dans le réhaut pour y loger le joint 18. Pour cacher la surface 17, le joint 18 et le réhaut 19, le dessous de la glace est pourvu d'une décoration 3 formant cadre et qui apparaît mieux sur la figure 1.The glass 1 and the two caps 5 (only one of which is shown in the drawing) thus form, in the embodiment according to the invention, a removable pre-assembly assembly which can be attached to the box or, on the contrary, separated from it for needs. maintenance or repair. The assembly in question is fixed to the middle by means of screws 16, arranged in pairs located one at 6 o'clock and the other at 12 o'clock. To ensure the tightness of the box, there is between the glass 1 and the flat upper face 17 of the middle part a sealing gasket 18 which the glass compresses when the screws 16 are tightened, the heads of which rest on the bottom of middle. These screws 16 are directly screwed into a tapped blind hole in the cap. In the case where the cap is made of hard material, as will appear below, the blind holes are provided with threaded sleeves 23 to receive the screws. In the execution of FIG. 2, we still see a floating flange 19 which keeps the dial 13 in place. In this embodiment, a notch is practiced both in the middle part and in the flange to accommodate the seal 18. To hide the surface 17, the seal 18 and the flange 19, the underside of the glass is provided with a decoration. 3 forming a frame and which appears better in FIG. 1.

La boite comprend encore un fond amovible 20. Selon l'invention, ce fond est vissé non pas dans la carrure comme c'est habituellement le cas mais dans le cercle d'agrandissement 11. Si la boite est de forme, ce cercle sera avantageusement réalisé en matière plastique et pourvu de manchons métalliques taraudés (non représentés) pour recevoir les vis 21 disposées également par paires de chaque côté de la boite. Une garniture 22 assure l'étanchéité du fond de boîte. On notera que ce mode de fixation du fond est avantageux pour l'aspect esthétique qu'on se propose d'atteindre ici car il permet de réduire la largeur 8 du maillon terminal 5, largeur prise dans le sens de la longueur du bracelet, à la largeur des autres maillons articulés du bracelet.The box also includes a removable bottom 20. According to the invention, this bottom is screwed not in the middle as is usually the case but in the enlargement circle 11. If the box is shaped, this circle will advantageously made of plastic and provided with threaded metal sleeves (not shown) to receive the screws 21 also arranged in pairs on each side of the box. A gasket 22 seals the bottom of the box. It will be noted that this method of fixing the bottom is advantageous for the aesthetic aspect which it is proposed to achieve here since it makes it possible to reduce the width 8 of the terminal link 5, width taken in the direction of the length of the bracelet, to the width of the other articulated links of the bracelet.

En s'aidant de la description qui vient d'être donnée, on peut donner alors les différentes phases de montage de la montre. On fixe le mouvement 12 au cercle 11 au moyen de brides (non représentées). On introduit le tout dans la carrure 9 par le haut de celle-ci. On pose le réhaut 19 et le joint 18. On colle de chaque côté de la glace 1 une coiffe 5 et on fixe l'ensemble ainsi constitué sur la carrure 9 au moyen de vis 16. Le fond 20 est à son tour assujetti à la boite au moyen de vis 21.With the help of the description which has just been given, it is then possible to give the different phases of assembly of the watch. Movement 12 is fixed to circle 11 by means of flanges (not shown). The whole is introduced into the middle part 9 from the top thereof. We place the flange 19 and the seal 18. We glue on each side of the glass 1 a cover 5 and the assembly thus formed is fixed to the middle part 9 by means of screws 16. The base 20 is in turn secured to the box by means of screws 21.

On voit l'avantage d'un tel montage. Lorsqu'il s'agit de remplacer la pile, il suffit d'enlever le fond. Cet accès facile n'existe pas avec les boites dites monocoques où le fond est fait d'une pièce avec la carrure comme c'est le cas de la construction faisant l'objet du brevet CH 592 911 cité plus haut. Par ailleurs si l'on doit accéder au mouvement proprement dit, il suffit d'enlever l'ensemble formé de la glace 1 et des deux coiffes 5. Cet ensemble formant un tout peut être facilement remonté avec précision et sans risquer d'endommager ni la métallisation 3 ni le joint 18 comme ce serait le cas si la glace devait être glissée dans une coulisse comme l'enseigne le même document cité.We see the advantage of such an assembly. When it comes to replacing the battery, just remove the bottom. This easy access does not exist with so-called monocoque boxes where the bottom is made in one piece with the middle part as is the case of the construction which is the subject of patent CH 592 911 cited above. Furthermore, if one has to access the movement proper, it suffices to remove the assembly formed from the glass 1 and from the two caps 5. This assembly forming a whole can be easily reassembled with precision and without risking damage or metallization 3 nor the seal 18 as would be the case if the glass were to be slid into a slide as shown in the same cited document.

On mentionnera également que la fixation par vis telle qu'elle est conçue ici évite toutes déformations que pourrait subir la boite de montre si cette fixation était réalisée au moyen de crochements. La fixation par vis des coiffes 5 par le dessous de carrure permet en outre de réduire au minimum la largeur du cadre métallisé 3 et d'offrir une plage d'affichage de surface maximum. En effet, dans cette construction, la face supérieure plane 17 de la carrure possède la même forme que le pourtour de la glace et est dépourvue de vis qu'il faudrait cacher par une métallisation plus large si de telles vis étaient présentes.It will also be mentioned that the screw fixing as it is designed here avoids any deformations that the watch case could undergo if this fixing was carried out by hooks. The fixing of the caps 5 by screws from the underside also makes it possible to minimize the width of the metallized frame 3 and to offer a maximum surface display range. In fact, in this construction, the flat upper face 17 of the middle part has the same shape as the periphery of the crystal and is devoid of screws which would have to be hidden by a wider metallization if such screws were present.

Généralement, la construction proposée conduit à une intégration parfaite du bracelet à la boite de montre puisque le maillon terminal dudit bracelet est amené au bord même de la glace sans fixations apparentes et que les maillons articulés qui lui font suite sont alignés sur lui sans discontinuité aucune. D'autre part, on a déjà relevé que la largeur 8 du maillon terminal 5 étant sensiblement égale à la largeur des autres maillons 6. Cette particularité accentue encore cet effet d'intégration.Generally, the proposed construction leads to a perfect integration of the strap into the watch case since the end link of said strap is brought to the very edge of the crystal without visible fastenings and that the articulated links which follow it are aligned on it without any discontinuity. . On the other hand, it has already been noted that the width 8 of the terminal link 5 is substantially equal to the width of the other links 6. This characteristic further accentuates this integration effect.

Le maillon terminal 5 et les maillons articulés 6 peuvent être réalisés dans tous matériaux convenables propres à être appliqués à une montre. On notera cependant que la construction telle qu'elle a été décrite se prête particulièrement bien à l'utilisation d'un matériau dur dont la dureté dépasse 1500 Vickers, comme par exempte le carbure de tungstène ou de titane ou encore le cermet. En effet, la configuration de la coiffe 5 formant maillon terminal est très simple et ne présente aucune creusure qui rendrait son usinage difficile. Cette coiffe peut donc être réalisée intégralement en matériau dur, comme d'ailleurs les maillons articulés qui lui font suite. On obtient alors une pièce dont l'aspect esthétique est nouveau et qui se distingue de la montre "tour de bras" en métal dur connue jusqu'ici où les maillons du bracelet en matériau courant servaient de support à des plaquettes en métal dur.The terminal link 5 and the articulated links 6 can be made of any suitable material suitable for being applied to a watch. It should be noted however that the construction as it has been described lends itself particularly well to the use of a hard material whose hardness exceeds 1500 Vickers, as for example tungsten or titanium carbide or even cermet. Indeed, the configuration of the cap 5 forming the end link is very simple and has no recess which would make its machining difficult. This cap can therefore be made entirely of hard material, like the articulated links which follow it. This gives a piece whose aesthetic appearance is new and which differs from the hard arm "arm watch" known hitherto where the links of the bracelet made of common material were used to support hard metal plates.

L'invention n'est pas limitée à une montre dont la glace présente un pourtour carré comme présentée sur la figure 1. Elle peut s'appliquer à des formes rectangulaires ou polygonales par exemple. Une construction similaire peut être adoptée pour une glace ronde. A ce moment, les coiffes 5 présentent une jonction semi-circulaire avec la glace.The invention is not limited to a watch whose crystal has a square periphery as shown in FIG. 1. It can be applied to rectangular or polygonal shapes for example. A similar construction can be adopted for a round window. At this time, the caps 5 have a semi-circular junction with the glass.
