Description

La présente invention concerne un dispositif pour régler l'orientation d'une couronne à vis d'une montre par rapport à la montre, ladite couronne pouvant prendre une position dévissée et une position vissée par rapport à la carrure sur un tube fixé à la carrure. La présente invention concerne également une montre comportant un tel dispositif.The present invention relates to a device for adjusting the orientation of a screw crown of a watch with respect to to the watch, said crown being able to assume a position unscrewed and a screwed position relative to the middle on a tube attached to the middle. The present invention also relates to a watch comprising such a device.

L'utilisation de couronnes à vis sur des montres est bien connue. En général, la couronne peut prendre une position dévissée dans laquelle il est possible de régler l'heure de la montre, la date etc. et une position vissée, qui est la position dans laquelle on porte la montre, dans laquelle la couronne est serrée et bloquée sur le tube de la montre.The use of screw crowns on watches is good known. In general, the crown can take a position in which it is possible to set the time of watch, date etc. and a screwed position, which is the position in which the watch is worn, in which the crown is tightened and locked on the watch tube.

Un problème auquel l'on est confronté avec les couronnes classiques est qu'il est très difficile, voire impossible, d'orienter de manière permanente au cours de la production, les filetages correspondants de la carrure de la montre et de la couronne de façon à ce que, pour chaque montre produite, la couronne vissée, soit toujours dans la même position relativement à la carrure. Cela peut poser des problème si la forme de la couronne n'est pas symétrique notamment, ou si la couronne comporte un logo particulier: la position de la couronne ou du logo par rapport à la carrure est alors différente pour chaque montre produite, une fois que la couronne est vissée.A problem we face with crowns classics is that it's very difficult, if not impossible, to orient permanently during the production, the corresponding threads of the middle part of the watch and of the crown so that, for each watch produced, the screwed crown, always in the same position relative to the middle. This can cause problem if the shape of the crown is not symmetrical in particular, or if the crown has a particular logo: the position of the crown or logo in relation to the middle is then different for each watch produced, once the crown is screwed down.

Le but de l'invention est d'améliorer les dispositifs connus. The object of the invention is to improve the devices known.

Plus particulièrement, l'invention a pour but de proposer un système simple qui permette d'ajuster de manière fine la position de la couronne vissée par rapport à la carrure, tout en conservant les qualités d'étanchéité de la montre.More particularly, the invention aims to propose a simple system that allows fine adjustment of the position of the screwed crown in relation to the middle part, while retaining the waterproof qualities of the watch.

Ce but est atteint par les caractéristiques de la revendication 1.This goal is achieved by the characteristics of the claim 1.

Les revendications dépendantes 2 à 5 définissent des modes d'exécution particuliers du système selon l'invention.Dependent claims 2 to 5 define modes particular execution of the system according to the invention.

La revendication 6 définit une montre comportant un dispositif selon l'invention.Claim 6 defines a watch comprising a device according to the invention.

L'invention sera mieux comprise par la description de deux modes d'exécution de celle-ci et des figures qui les accompagnent.The invention will be better understood by the description of two modes of execution thereof and of the figures which accompany.

La figure 1 montre une vue en coupe d'un premier mode d'exécution de l'invention.Figure 1 shows a sectional view of a first mode of the invention.

La figure 2 montre une vue en coupe d'un deuxième mode d'exécution de l'invention.Figure 2 shows a sectional view of a second mode of the invention.

Dans la figure 1, on a représenté, à titre d'exemple, le premier mode d'exécution de l'invention. Dans ce mode, on trouve une couronne 1 qui est vissée sur un tube 2, ledit tube étant lui-même fixé à la carrure 3 de la montre. Cette couronne peut en outre comporter un logo 4, schématisé par des traits tiretés. De manière classique, plusieurs joints sont placés entre la couronne et le tube pour assurer l'étanchéité, à savoir un joint O-ring 5 et un premier joint plat 6 qui est comprimé lors du vissage de la couronne 1 sur le tube 2.In Figure 1, there is shown, by way of example, the first embodiment of the invention. In this mode, finds a crown 1 which is screwed onto a tube 2, said tube itself being fixed to the middle part 3 of the watch. This crown may further include a logo 4, shown schematically by dashed lines. Conventionally, several joints are placed between the crown and the tube to ensure sealing, namely an O-ring 5 and a first flat seal 6 which is compressed when the crown 1 on tube 2.

Le vissage de la couronne 1 sur le tube 2 s'effectue par l'intermédiaire d'un taraudage 7 approprié dans la couronne 1 et d'un filetage 8 correspondant sur le tube 2.The crown 1 is screwed onto the tube 2 by via an appropriate tapping 7 in the crown 1 and a corresponding thread 8 on the tube 2.

On trouve encore un deuxième joint plat 9 entre le tube 2 et la carrure 3 qui permet d'assurer l'étanchéité du boítier de montre. Ce deuxième joint plat est facultatif lorsque le tube 2 est soudé ou chassé sur la carrure 3.There is also a second flat seal 9 between the tube 2 and the middle part 3 which ensures the tightness of the watch case. This second flat seal is optional when the tube 2 is welded or driven onto the middle part 3.

Les moyens permettant l'ajustement de la position de la couronne 1 par rapport à la carrure 3 de la montre comprennent une bague 10 qui est placée entre la carrure 3 et le tube 2. Pour le mode d'exécution de la figure 1, cette bague 10 est formée dans un alliage métallique à mémoire de forme, par exemple un alliage de nickel-titane comme l'alliage "Micro-Niti" de la société Microfil Industries S.A. Grâce à cette bague intermédiaire, on obtient un système qui permet un ajustement angulaire de la couronne 1. En effet, en utilisant de manière appropriée l'effet de mémoire de forme lié à la température, il est possible de réaliser un système permettant un ajustement fin qui est indépendant du début du filetage 8 du tube 2 et du début du taraudage 7 de la couronne 1. Dans le cas présent, il est nécessaire que la bague 10 ferme de manière complètement étanche la liaison qu'elle réalise entre la carrure 3 et le tube 2, à la température ambiante et malgré des écarts de température normaux que pourrait subir une montre qui est portée. Ainsi, la rotation du tube 2 est bloquée et la position de la couronne 1 vissée par rapport à la carrure 3 est fixe. Means for adjusting the position of the crown 1 relative to the middle 3 of the watch include a ring 10 which is placed between the middle part 3 and tube 2. For the embodiment of FIG. 1, this ring 10 is formed from a metal alloy with shape memory, for example a nickel-titanium alloy like the "Micro-Niti" alloy from Microfil Industries S.A. Thanks to this intermediate ring, obtains a system which allows an angular adjustment of the crown 1. Indeed, using appropriately the temperature memory effect related to temperature it's possible to realize a system allowing an adjustment end which is independent of the start of the thread 8 of the tube 2 and from the start of the tapping 7 of the crown 1. In the case present, it is necessary that the ring 10 closes so completely sealed the connection it makes between the middle 3 and tube 2, at room temperature and despite normal temperature differences that a shows who is being worn. So the rotation of tube 2 is locked and the position of the crown 1 screwed relative to the middle part 3 is fixed.

En revanche, en utilisant des températures particulières, qui dépendent de l'alliage utilisé pour la bague 10, on peut arriver à diminuer la taille de la bague 10 et ainsi permettre une rotation du tube 2 par rapport à la carrure 3. Lors du montage d'une montre, il est alors très facile de régler la position d'une couronne 1 serrée sur le tube 2 en créant un jeu temporaire entre le tube 2 et la carrure 3 par contraction de la bague 10. Ainsi, on obtient des séries de montres qui, après ajustement, comportent des couronnes vissées orientées toutes dans la même direction par rapport à la carrure.However, using specific temperatures, which depend on the alloy used for ring 10, we can reduce the size of the ring 10 and so allow rotation of the tube 2 relative to the middle part 3. When mounting a watch, it is then very easy to adjust the position of a crown 1 tight on the tube 2 by creating a temporary clearance between the tube 2 and the middle part 3 by contraction of the ring 10. Thus, we obtain series of watches which, after adjustment, include screw-down crowns all oriented in the same direction compared to the middle.

La figure 2 montre une deuxième forme d'exécution de l'invention, dans laquelle, les éléments identiques au premier mode d'exécution ont les mêmes références, la principale différence résidant dans la position de la bague 10 de la figure 1. Dans ce cas en effet, la bague porte la référence 11 et se trouve non pas entre le tube 2 et la carrure 3 (voir figure 1) mais entre la couronne 1 elle-même et le tube 2. En fait, le tube 2 est chassé de manière classique dans la carrure de la montre (non-représentée), et c'est la bague 11 elle-même qui supporte le taraudage 12 de la couronne 1 qui est destiné à se visser sur le filetage du tube 2. De même que dans le premier mode d'exécution de la figure 1, en jouant sur la déformation de la bague 11, en particulier en diminuant son diamètre, on peut créer un jeu temporaire entre la couronne 1 et le tube 2, ce qui permet d'ajuster angulairement la position vissée de la couronne sur le tube 2. Celui-ci étant fixe par rapport à la carrure, on ajuste par conséquent la position angulaire de la couronne 1 par rapport au boítier de la montre elle-même. Figure 2 shows a second embodiment of the invention, in which the elements identical to first embodiment have the same references, the main difference residing in the position of the ring 10 of FIG. 1. In this case, in fact, the ring carries the reference 11 and is not between the tube 2 and the middle 3 (see figure 1) but between the crown 1 itself and the tube 2. In fact, the tube 2 is expelled so classic in the middle of the watch (not shown), and it is the ring 11 itself which supports the tapping 12 crown 1 which is intended to be screwed onto the pipe thread 2. As in the first mode of execution of FIG. 1, by playing on the deformation of the ring 11, in particular by reducing its diameter, we can create a temporary clearance between crown 1 and the tube 2, which allows angular adjustment of the screwed position of the crown on the tube 2. The latter being fixed by in relation to the middle, we therefore adjust the position angular of the crown 1 with respect to the case of the shows itself.

Bien entendu, l'utilisation de bague en alliage à mémoire de forme est un exemple non-limitatif. D'autres alliages sont possibles. De même, d'autres systèmes équivalents permettant en particulier de créer temporairement un jeu entre la couronne et la carrure de la montre sont possibles, l'idée étant de permettre un tel jeu que dans des conditions particulières et de l'empêcher dans des conditions d'utilisation normales.Of course, the use of memory alloy rings form is a non-limiting example. Other alloys are possible. Similarly, other equivalent systems allowing in particular to temporarily create a game between the crown and the middle of the watch are possible, the idea being to allow such a game as in particular conditions and prevent it in normal conditions of use.
