Description

L'invention est relative à une pièce d'horlogerie analogique pourvue d'aiguilles en rotation entre un cadran et une première glace et un motif décoratif solidaire d'un axe d'aiguille et tournant avec lui, ledit axe émergeant dudit cadran sous ladite première glace, ledit motif présentant un pourtour sensiblement circulaire situé dans un plan parallèle au cadran.The invention relates to an analog timepiece provided with rotating needles between a dial and a first crystal and a decorative pattern integral with a needle axis and rotating with it, said axis emerging from said dial under said first crystal, said pattern having a substantially circular periphery situated in a plane parallel to the dial.

Le document CH-A-658 969 décrit déjà une montre avec ornement mobile et son procédé de montage. Cette montre est ornée d'une pierre sertie fixée à l'axe d'une aiguille. La pierre est sertie par rabattement de griffes faisant partie d'un chaton solidaire de l'axe de l'aiguille.The document CH-A-658 969 already describes a watch with mobile ornament and its method of assembly. This watch is adorned with a set stone attached to the axis of a hand. The stone is crimped by folding claws forming part of a kitten secured to the axis of the needle.

Un autre dispositif plus lourd et plus compliqué est proposé par le document US-A-2 536 206 où un diamant est enchâssé dans un chaton tournant avec l'aiguille des minutes.Another heavier and more complicated device is proposed by document US-A-2,536,206 where a diamond is set in a rotating kitten with the minute hand.

Aucun des titulaires des documents cités ne s'est posé la question de savoir si le dispositif décrit était résistant aux chocs qui peuvent intervenir lors du porter de la pièce d'horlogerie. Le titulaire de la présente demande, désireux de mettre sur le marché un tel dispositif, par ailleurs connu des documents cités, a soumis des pièces aux tests normalisés - dont des chocs - qui précédent généralement la libération pour la vente du produit terminé. Il s'est aperçu après ces tests (par exemple un choc résultant d'une accélération de 5000 g dans la direction de l'axe de la tige de mise à l'heure) que l'axe d'aiguille supportant le décor était pliée de manière permanente. Comme il n'est guère possible de renforcer l'axe supportant le décor, il a été remédié à l'inconvénient cité en proposant une paroi de protection fixe disposée avec jeu autour du pourtour du décor pour limiter son déplacement lorsqu'un choc est appliqué à la pièce d'horlogerie.None of the holders of the cited documents asked themselves the question of knowing whether the device described was resistant to shocks which may occur during the wearing of the timepiece. The holder of this application, wishing to market such a device, also known from the cited documents, has submitted parts to standardized tests - including shocks - which generally precedes release for the sale of the finished product. He noticed after these tests (for example a shock resulting from an acceleration of 5000 g in the direction of the axis of the time-setting rod) that the needle axis supporting the decoration was bent Permanently. As it is hardly possible to reinforce the axis supporting the decoration, it has been remedied the aforementioned drawback by proposing a fixed protective wall arranged with play around the periphery of the decoration to limit its movement when a shock is applied. to the timepiece.

L'invention sera comprise maintenant de la description qui suit et du dessin qui l'illustre, donné à titre d'exemple et dans lequel :

  • la figure 1 est une coupe dans la pièce d'horlogerie de l'invention selon un premier mode d'exécution de l'invention,
  • la figure 2 montre un second mode d'exécution de l'invention, et
  • la figure 3 montre un troisième mode d'exécution de l'invention.
The invention will now be understood from the description which follows and from the drawing which illustrates it, given by way of example and in which:
  • FIG. 1 is a section through the timepiece of the invention according to a first embodiment of the invention,
  • FIG. 2 shows a second embodiment of the invention, and
  • Figure 3 shows a third embodiment of the invention.

La figure 1 montre un premier mode d'exécution qui est aussi le mode préféré. La pièce d'horlogerie, qui est ici une montre-bracelet, est pourvue d'aiguilles de minutes 9 et d'heures 10 entraînées en rotation entre un cadran 5 et une première glace 1. L'aiguille des heures 10 est emmanchée sur la roue à canon 7 sur laquelle est chassée la roue des heures 15 et l'aiguille des minutes est emmanchée sur la chaussée 6 comme cela se présente sur un montage classique. Un motif décoratif 30 est solidaire d'un axe d'aiguille, ici l'axe des secondes 8, et tourne avec cet axe. Comme le montre aussi la figure 1, l'axe 8 émerge du cadran 5 par son extrémité 12 sous la première glace 1. Le motif décoratif 30 présente un pourtour 31 sensiblement circulaire situé dans un plan parallèle au cadran 5. L'invention consiste à disposer avec un jeu x une paroi de protection fixe 11 autour du pourtour 31 pour limiter le déplacement du motif lorsqu'un choc est appliqué à la montre.Figure 1 shows a first embodiment which is also the preferred mode. The timepiece, which is here a wristwatch, is provided with minute hands 9 and hours 10 rotated between a dial 5 and a first crystal 1. The hour hand 10 is fitted on the barrel wheel 7 on which the hour wheel 15 is driven and the minute hand is fitted onto the carriageway 6 as is the case with a conventional assembly. A decorative pattern 30 is integral with a needle axis, here the seconds axis 8, and rotates with this axis. As also shown in FIG. 1, the axis 8 emerges from the dial 5 at its end 12 under the first crystal 1. The decorative pattern 30 has a substantially circular periphery 31 situated in a plane parallel to the dial 5. The invention consists in arrange with a set x a fixed protective wall 11 around the periphery 31 to limit the movement of the pattern when a shock is applied to the watch.

Dans le mode d'exécution de la figure 1, la paroi de protection 11 est un perçage pratiqué dans une seconde glace 2 disposée entre le cadran 5 et la première glace 1. Cette figure montre un exemple d'assujettissement des première 1 et seconde 2 glaces sur la carrure 3 de la montre. Cette carrure présente un épaulement 17 sur lequel repose le cadran 5. Pour maintenir ce cadran en place on vient appuyer sur lui la glace 1 en même temps qu'on soude par ultrason ladite glace à la carrure comme cela est décrit dans le document EP-B-0 101 663 (= US-A-4 558 957). Après le posage du cadran 5, mais avant le soudage de la glace 1, on pose la glace 2 sur le cadran, laquelle est maintenue en place une fois la glace 1 soudée sur la carrure 3.In the embodiment of Figure 1, the protective wall 11 is a hole made in a second glass 2 disposed between the dial 5 and the first glass 1. This figure shows an example of securing the first 1 and second 2 glass on the middle part 3 of the watch. This middle part has a shoulder 17 on which the dial 5 rests. To keep this dial in place, the glass 1 is pressed against it at the same time as said glass is welded to the middle part as described in the document EP- B-0 101 663 (= US-A-4 558 957). After fitting the dial 5, but before welding the glass 1, the glass 2 is placed on the dial, which is held in place once the glass 1 is welded to the middle part 3.

Le motif décoratif 30 est ici une pierre 14 à facettes enchâssée dans un chaton 13, ce dernier étant emmanché sur l'extrémité 12 de l'axe des secondes 8. La pierre peut être un diamant ou tout autre pierre précieuse. Ce pourrait être aussi un métal précieux, de l'or par exemple. Le jeu x existant entre la paroi 11 et le pourtour 31 du décor doit être assez grand pour assurer un montage aisé de la montre mais limité cependant en dimension pour que, lors d'un choc exercé sur la montre, le pourtour 31 du décor 30 vienne toucher la paroi 11 avant que la limite élastique de l'axe des secondes 8, 12 ne soit dépassée (quelques dizièmes de millimètre).The decorative pattern 30 is here a faceted stone 14 embedded in a kitten 13, the latter being fitted onto the end 12 of the seconds axis 8. The stone may be a diamond or any other precious stone. It could also be a precious metal, gold for example. The clearance x existing between the wall 11 and the periphery 31 of the decoration must be large enough to ensure easy assembly of the watch but limited however in size so that, during an impact exerted on the watch, the periphery 31 of the decoration 30 come and touch the wall 11 before the elastic limit of the seconds axis 8, 12 is exceeded (a few tenths of a millimeter).

La figure 2 montre un deuxième mode d'exécution de l'invention où la paroi de protection 11 est réalisée par un tube 21 disposé sous la première glace 20 et préférablement fait d'une pièce avec elle.Figure 2 shows a second embodiment of the invention where the protective wall 11 is formed by a tube 21 disposed under the first glass 20 and preferably made in one piece with it.

La figure 3 montre un troisième mode d'exécution de l'invention où la paroi de protection 11 est réalisée au moyen d'une bulle 26 levée dans la glace 25.FIG. 3 shows a third embodiment of the invention where the protective wall 11 is produced by means of a bubble 26 lifted in the glass 25.

Dans les exécutions des figures 2 et 3 les glaces 20, respectivement 25 peuvent être fixée à la carrure de la même manière que celle décrite ci-dessus à propos de la figure 1.In the embodiments of FIGS. 2 and 3, the windows 20, respectively 25 can be fixed to the middle part in the same manner as that described above with reference to FIG. 1.

On mentionnera encore que l'axe des secondes peut porter, en plus du motif décoratif, une aiguille des secondes comme cela est montré dans le document CH-B-658 969 précédemment cité.It will also be mentioned that the seconds axis can carry, in addition to the decorative pattern, a seconds hand as shown in the document CH-B-658 969 previously cited.
