Abstract

The components of a mechanical watch are mounted inside a supporting structure comprising a stack of transparent plates made of corundum, spinel or quartz. Some of the plates are formed with cut-outs which define in the assembled structure housings for accommodating said components.

Description

La présente invention concerne un dispositif portatif du type comprenant un bâti-support, une source d'énergie, un organe moteur rotatif alimenté par cette source et un train d'engrenages entraîné par ledit organe moteur.The present invention relates to a portable device of the type comprising a support frame, a power source, a rotary drive member powered by this source and a gear train driven by said drive member.

Parmi les dispositifs connus répondant à cette définition, on connaît, par exemple, les montres-bracelets et les montres de poche. Le caractère esthétique de ces pièces est généralement défini par la boîte, le cadran et les aiguilles. Certaines pièces plus originales, connues sous le nom de montres-squelettes, comportent une platine et des ponts ajourés qui permettent une vision partielle de leurs parties mobiles.Among the known devices corresponding to this definition, there are known, for example, wristwatches and pocket watches. The aesthetic character of these parts is generally defined by the case, the dial and the hands. Some more original pieces, known as skeleton watches, have a plate and openwork bridges that allow a partial view of their moving parts.

La présente invention a pour but de fournir un dispositif du genre ci-dessus qui, à la différence des dispositifs connus, non seulement offre une vision très large de ses éléments constitutifs, mais aussi présente des effets esthétiques intéressants.The object of the present invention is to provide a device of the above kind which, unlike known devices, not only offers a very broad view of its constituent elements, but also has interesting aesthetic effects.

Ce but est atteint grâce au fait que le bâti-support est constitué par un empilement de plaques transparentes dont certaines sont découpées de manière à former des logements pour les éléments constitutifs du dispositif.This object is achieved thanks to the fact that the support frame is constituted by a stack of transparent plates, some of which are cut so as to form housings for the constituent elements of the device.

L'invention sera mieux comprise à la lecture de la description qui va suivre, faite en regard des dessins annexés.The invention will be better understood on reading the description which follows, made with reference to the appended drawings.

Sur ces dessins :

  • - la figure 1 est une vue éclatée d'une montre munie d'un bâti-support selon l'invention; et
  • - la figure 2 est une vue en plan de la même montre.
In these drawings:
  • - Figure 1 is an exploded view of a watch provided with a support frame according to the invention; and
  • - Figure 2 is a plan view of the same watch.

La montre représentée aux figures 1 et 2 comporte un bâti- support formé d'un empilement des plaques rectangulaires désignées par les numéros pairs allant de 10 à 28. Ces plaques sont faites de matière transparente, avantageusement du corindon (saphir, rubis), du spinelle, du quartz, voire du verre ou de la matière plastique.The watch shown in FIGS. 1 and 2 comprises a support structure formed by a stack of rectangular plates designated by the even numbers ranging from 10 to 28. These plates are made of transparent material, advantageously corundum (sapphire, ruby), spinel, quartz, even glass or plastic.

La plaque supérieure 10 constitue la glace, tandis que la plaque inférieure 28 constitue le fond.The upper plate 10 constitutes the glass, while the lower plate 28 constitutes the bottom.

Les plaques 12 à 26 sont découpées intérieurement de manière à constituer, lorsqu'elles sont empilées, des logements pour les pièces constitutives du mouvement de la montre. Celui-ci apparaît de façon détaillée sur la figure 2, mais n'est représenté que très schématiquement sur la figure 1.The plates 12 to 26 are cut internally so as to constitute, when stacked, housings for the constituent parts of the watch movement. This appears in detail in Figure 2, but is only shown very schematically in Figure 1.

Il comporte essentiellement :

  • - un ressort 30 (visible seulement à la figure 2) formant la source d'énergie;
  • - un barillet 32 contenant le ressort 30 et formant l'organe moteur;
  • - un train d'engrenages 34 couplé au barillet;
  • - des aiguilles de minute 36 et d'heure 38 entraînées par le train d'engrenages;
  • - un échappement 40 et un balancier 42 pour assurer la régulation du mouvement du train d'engrenages;
  • - une tige 44 sur laquelle est monté un pignon 45 (visible seulement sur la figure 2);
  • - un mécanisme de remontoir et de mise à l'heure comportant une tirette 46 actionnable par la tige 44, un renvoi de mise à l'heure 48 monté pivotant sur la tirette, un ressort de tirette 50, une bascule 52 actionnable par la tirette, un renvoi de remontoir 54 (visible seulement sur la figure 2) monté pivotant sur la bascule 52, un ressort de bascule 56, une couronne 58, entraînée en rotation par le pignon 45 et engrenant avec les renvois 48 et 54, une roue de rochet 60 (visible seulement sur la figure 1) montée sur l'arbre du barillet 32 et finalement un cliquet 62 et son ressort 64.
It essentially includes:
  • - A spring 30 (visible only in Figure 2) forming the energy source;
  • - A barrel 32 containing the spring 30 and forming the driving member;
  • - a gear train 34 coupled to the barrel;
  • - minute 36 and hour 38 hands driven by the gear train;
  • - an exhaust 40 and a pendulum 42 for regulating the movement of the gear train;
  • - A rod 44 on which is mounted a pinion 45 (visible only in Figure 2);
  • - A winding and time-setting mechanism comprising a pull tab 46 actuable by the rod 44, a time setting reference 48 pivotally mounted on the pull tab, a pull spring 50, a rocker 52 actuable by the pull tab , a winding gear 54 (visible only in Figure 2) pivotally mounted on the rocker 52, a rocker spring 56, a crown 58, driven in rotation by the pinion 45 and meshing with the references 48 and 54, a wheel ratchet 60 (visible only in FIG. 1) mounted on the barrel shaft 32 and finally a pawl 62 and its spring 64.

La plaque 12 comporte une ouverture circulaire 66 et la plaque 14 une ouverture circulaire 68, de plus petit diamètre, à l'intérieur desquelles se trouvent respectivement l'aiguille de minute 36 et l'aiguille d'heure 38.The plate 12 has a circular opening 66 and the plate 14 a circular opening 68, of smaller diameter, inside which are respectively the minute hand 36 and the hour hand 38.

Le barillet 32, qui contient le ressort 30, occupe un logement formé par des ouvertures circulaires 70, 72, 74 et 76 respectivement pratiquées dans les plaques 16, 18, 20 et 22. Les extrémités de l'arbre du barillet pivotent dans des trous 78 et 80 des plaques 14 et 24 respectivement.The barrel 32, which contains the spring 30, occupies a housing formed by circular openings 70, 72, 74 and 76 respectively formed in the plates 16, 18, 20 and 22. The ends of the barrel shaft pivot in holes 78 and 80 of plates 14 and 24 respectively.

Le rouage 34 et l'échappement 40 occupent un logement formé par des ouvertures de formes appropriées 82, 84 et 86, pratiquées dans les plaques 18, 20 et 22 respectivement. Ils pivotent dans des trous (non référencés) qui sont percés dans les plaques 16, 18 et 24.The train 34 and the exhaust 40 occupy a housing formed by openings of appropriate shapes 82, 84 and 86, made in the plates 18, 20 and 22 respectively. They pivot in holes (not referenced) which are drilled in the plates 16, 18 and 24.

Le balancier 42 se trouve dans un logement, défini par des ouvertures circulaires 88, 90; 92 et 94 que comportent les plaques 16, 18, 20 et 22 respectivement. Il pivote dans des trous (non référencés), pratiqués dans des plaques 14 et 24.The pendulum 42 is located in a housing, defined by circular openings 88, 90; 92 and 94 that comprise the plates 16, 18, 20 and 22 respectively. It pivots in holes (not referenced), made in plates 14 and 24.

Les pièces 46 à 64 constitutives du mécanisme de remontoir et de mise à l'heure prennent place dans un logement que définissent des ouvertures 96 et 98 pratiquées dans les plaques 24 et 26. La ti.rette 46 et la bascule 52 pivotent dans des trous (non référencés) percés dans la plaque 22, tandis que la couronne 58 et le cliquet 62 pivotent dans des trous (non référencés) de 1a plaque 24.The parts 46 to 64 constituting the winding and time-setting mechanism take place in a housing defined by openings 96 and 98 made in the plates 24 and 26. The ti.rette 46 and the rocker 52 pivot in holes (not referenced) drilled in the plate 22, while the crown 58 and the pawl 62 pivot in holes (not referenced) of the plate 24.

Enfin, la tige 44 pivote dans un tube 100, collé dans un logement 102 que comporte 1a plapue 22.Finally, the rod 44 pivots in a tube 100, glued in a housing 102 that includes the plume 22.

Les plaques 10 à 28 sont assemblées au moyen de quatre vis 104 et de quatre pied-vis 106, respectivement engagés dans des trous 108, pratiqués dans chacune des plaques, à l'exception de la plaque 22.The plates 10 to 28 are assembled by means of four screws 104 and four screw feet 106, respectively engaged in holes 108, made in each of the plates, with the exception of plate 22.

Cette dernière, moins longue que les autres, comporte quatre trous 110 qui permettent de 1a positionner sur 1a plaque 24 au moyen de quatre pieds 112 solidaires de celle-ci et s'engageant dans les trous 110. Grâce à' cette disposition, il est possible d'insérer entre les plaques 20 et 24, aux extrémités de la plaque 22, deux attaches.de bracelet 114 et 116 qui comportent des trous 118 pour le passage des pied-vis 106.The latter, which is shorter than the others, has four holes 110 which make it possible to position it on the plate 24 by means of four feet 112 integral with the latter and engaging in the holes 110. Thanks to this arrangement, it is possible to insert between the plates 20 and 24, at the ends of the plate 22, two strap fasteners 114 and 116 which have holes 118 for the passage of the foot-screws 106.

La plaque 22 est ici plus épaisse que les autres afin de permettre l'usage d'une tige de mise à l'heure et d'attaches de bracelet suffisamment rigides pour supporter les contraintes normales auxquelles une montre peut être soumise.The plate 22 is here thicker than the others in order to allow the use of a time-setting rod and strap fasteners sufficiently rigid to withstand the normal stresses to which a watch may be subjected.

Les ouvertures peuvent être découpées dans les plaques par tout moyen approprié. Dans le cas du corindon et du spinelle, le découpage est avantageusement réalisé par faisceau laser ou par ultrasons. Quant au quartz, il se prête plus facilement à un découpage par un procédé photo-chimique.The openings can be cut from the plates by any suitable means. In the case of corundum and spinel, the cutting is advantageously carried out by laser beam or by ultrasound. As for quartz, it lends itself more easily to cutting by a photo-chemical process.

Il va de soi que l'invention n'est pas limitée au seul mode de réalisation qui vient d'être décrit. Notamment, le nombre de plaques utilisées peut être augmenté ou réduit. Quant à la forme des ouvertures pratiquées dans les plaques, elle peut soit correspondre assez exactement, comme représenté sur la figure 1, à la forme des pièces constitutives du mouvement, soit au contraire s'en éloigner de manière à produire, par elle-même, des effets esthétiques particuliers.It goes without saying that the invention is not limited to the single embodiment which has just been described. In particular, the number of plates used can be increased or reduced. As for the shape of the openings made in the plates, it can either correspond fairly exactly, as shown in Figure 1, the shape of the constituent parts of the movement, or on the contrary move away from it so as to produce, by itself, particular aesthetic effects.

Ainsi, l'invention offre la possibilité, non seulement, grâce à l'utilisation de plaques transparentes, de réaliser une montre dont toutes les pièces sont visibles, mais aussi, en jouant sur la couleur des plaques et la forme de leurs ouvertures, de créer des effets esthétiques très particuliers qui confèrent a l'ensemble un aspect proche de celui d'un vitrail.Thus, the invention offers the possibility, not only, through the use of transparent plates, of making a watch in which all the parts are visible, but also, by playing on the color of the plates and the shape of their openings, create very special aesthetic effects which give the whole an aspect close to that of a stained glass window.

Il est aussi possible de déposer sur les plaques, ou au moins certaines d'entre elles, un revêtement coloré très mince, de l'ordre de quelques microns, qui contribue à l'esthétique de la montre.It is also possible to deposit on the plates, or at least some of them, a very thin colored coating, of the order of a few microns, which contributes to the aesthetics of the watch.

L'utilisation de plaques en corindon permet de réaliser une montre particulièrement remarquable. Ce matériau a une dureté qui lui confère une très grande résistance à l'abrasion. De plus, il est possible de réaliser des plaques dont l'épaisseur peut atteindre 0,2 à 0,3 mm, ce qui permet de multiplier le nombre de plaques et augmente donc les possibilités de créer des effets esthétiques.The use of corundum plates makes it possible to produce a particularly remarkable watch. This material has a hardness which gives it a very high resistance to abrasion. In addition, it is possible to produce plates whose thickness can reach 0.2 to 0.3 mm, which makes it possible to multiply the number of plates and therefore increases the possibilities of creating aesthetic effects.

Il faut enfin noter que, d'une part, l'utilisation de matériaux durs, surtout tels que le corindon et le spinelle, mais aussi le quartz et, d'autre part, la possibilité offerte de limiter au strict minimum les ajourages qui affaiblissent la structure des montres squelettes, permettent de réaliser une montre mince, d'aspect particulièrement original, possédant une excellente rigidité et laissant visible ses parties mobiles.It should finally be noted that, on the one hand, the use of hard materials, especially such as corundum and spinel, but also quartz and, on the other hand, the possibility offered to limit to the strict minimum the openings which weaken the structure of the skeleton watches makes it possible to produce a thin watch, of particularly original appearance, having excellent rigidity and leaving visible its moving parts.

Le résultat obtenu sur le plan esthétique est tel qu'il se suffit à lui-même et qu'en conséquence, la fonction d'affichage de l'heure peut être supprimée pour ne laisser qu'un ensemble de mobiles intégrés dans une sorte de vitrail.The aesthetic result is such that it is self-sufficient and that consequently, the time display function can be omitted to leave only a set of mobiles integrated in a sort of stained glass.
