Description

La présente invention concerne les couronnes à vis ou couronnes vissées pour pièces d'horlogerie et plus particulièrement de telles couronnes comportant un motif ou un logo sur leur face d'extrémité et dans lesquelles ledit motif peut être orienté à souhait.The present invention relates to screw crowns or screw crowns for timepieces and more particularly such crowns having a pattern or a logo on their end face and in which said pattern can be oriented at wish.

Les couronnes à vis sont couramment utilisées pour équiper des montres dans le but d'améliorer l'étanchéité de celles-ci au niveau de leur tige de remontage ou de commande. Ce type de couronne a la particularité de pouvoir prendre une position dévissée dans laquelle la montre peut être remontée, mise à l'heure etc. et une position vissée dans laquelle la couronne est vissée et bloquée sur un tube chassé dans la carrure de la boíte de montre afin de comprimer un joint d'étanchéité, améliorant ainsi l'étanchéité de la montre. La position vissée est donc celle qui correspond à la position normale lorsque la montre est portée.Screw crowns are commonly used to equip watches in the purpose of improving the tightness of these at their winding rod or ordered. This type of crown has the distinction of being able to take a position unscrewed in which the watch can be wound, set the time etc. and an screwed position in which the crown is screwed and locked on a driven tube in the middle of the watch case in order to compress a seal, thus improving the water resistance of the watch. The screwed position is therefore that which corresponds to the normal position when the watch is worn.

La fabrication et le montage de ces couronnes vissées sur des boites de montre sont bien connus. Toutefois, les procédés de montage de ces couronnes sont mal adaptés aux couronnes vissées portant sur leur face d'extrémité une inscription ou un motif par exemple un logo, une marque de fabrique ou analogue. En effet, les procédés de montage connus ne permettent pas toujours d'amener la couronne dans une orientation déterminée par rapport à la boíte après leur dévissage, ce qui nuit à l'esthétique de la boíte lorsqu'une inscription est apposée sur la face d'extrémité de la couronne. Cette situation est bien entendu inacceptable lorsque ces couronnes équipent des produits de luxe et de haute qualité.The manufacture and assembly of these crowns screwed on boxes of watches are well known. However, the methods of mounting these crowns are unsuitable for screwed crowns with an inscription on their end face or a motif, for example a logo, a trademark or the like. Indeed, the known mounting methods do not always allow the crown to be brought into a determined orientation relative to the box after their unscrewing, which harms the aesthetics of the box when an inscription is affixed on the end face of the crowned. This situation is of course unacceptable when these crowns equip luxury and high quality products.

La présente invention a pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant une couronne à vis de construction simple et économique, comportant un motif tel qu'un logo ou une marque et dans laquelle la position du logo ou de la marque apposé sur la face d'extrémité de ladite couronne peut être aisément ajustée dans une position ou orientation déterminée après vissage de la couronne sur le tube.The main object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a screw crown of simple construction and economical, with a motif such as a logo or a brand and in which the position of the logo or mark affixed on the end face of said crown can be easily adjusted in a determined position or orientation after screwing of the crown on the tube.

A cet effet, l'invention a pour objet une couronne à vis pour pièce d'horlogerie comportant une tête, une partie centrale et une jupe latérale, la tête comportant une face d'extrémité portant un motif, la couronne étant caractérisée en ce que la face d'extrémité comprend un substrat sur une face duquel est apposé le motif, en ce que le substrat est monté mobile à rotation dans la tête et en ce que la couronne comprend en outre des moyens de freinage agencés pour maintenir le substrat par rapport à la tête dans différentes orientations angulaires autour de l'axe de rotation de la couronne. To this end, the invention relates to a screw crown for a timepiece comprising a head, a central part and a side skirt, the head comprising a end face bearing a pattern, the crown being characterized in that the face end comprises a substrate on one face of which the pattern is affixed, in that the substrate is mounted mobile in rotation in the head and in that the crown further comprises braking means arranged to hold the substrate by relation to the head in different angular orientations around the axis of rotation of the crown.

Grâce à ces caractéristiques, l'orientation du motif porté par le substrat peut être aisément ajustée dans la position désirée par rapport à la carrure une fois dans la position vissée de la couronne, par simple rotation du substrat relative à la tête contre la force des moyens de freinage. La force de freinage engendrée par lesdits moyens de freinage est bien entendu ajustée pour que le substrat ne puisse pas être mis en rotation de manière intempestive lorsque la montre est portée, tout en autorisant un mouvement de ce dernier permettant l'ajustement de l'orientation.Thanks to these characteristics, the orientation of the pattern carried by the substrate can be easily adjusted in the desired position relative to the middle part once in the screwed position of the crown, by simple rotation of the substrate relative to the head against the force of the braking means. The braking force generated by said means of braking is of course adjusted so that the substrate cannot be untimely rotation when the watch is worn, while allowing a movement of the latter allowing the orientation to be adjusted.

Selon une caractéristique avantageuse de l'invention, les moyens de freinage agissent par frottement sur le substrat. L'utilisation d'un freinage par frottement permet de réaliser un ajustement continu et fin de l'orientation du substrat et donc du motif par rapport à la carrure de la boíte de montre.According to an advantageous characteristic of the invention, the braking means act by friction on the substrate. The use of friction braking allows a continuous and fine adjustment of the orientation of the substrate and therefore of the pattern in relation to the middle of the watch case.

D'autres caractéristiques et avantages de la présente invention apparaítront dans la description suivante d'un mode de réalisation préféré, présenté à titre d'exemple non limitatif en référence aux dessins annexés, dans lesquels :

  • la figure 1 montre une vue frontale d'une couronne à vis selon l'invention, et
  • la figure 2 montre une vue coupe de la couronne à vis selon l'invention suivant la ligne II-II de la figure 1.
Other characteristics and advantages of the present invention will appear in the following description of a preferred embodiment, presented by way of nonlimiting example with reference to the accompanying drawings, in which:
  • FIG. 1 shows a front view of a screw crown according to the invention, and
  • FIG. 2 shows a sectional view of the screw crown according to the invention along the line II-II of FIG. 1.

Aux figures 1 et 2, on voit une couronne à vis désignée par la référence générale 1 et destinée à être vissée sur un tube fileté (non représenté) chassé dans la carrure d'une boíte de montre (également non représentée).In Figures 1 and 2, we see a screw crown designated by the reference general 1 and intended to be screwed onto a threaded tube (not shown) driven into the middle of a watch case (also not shown).

La couronne 1 comprend une première partie formée d'une tête 2 prolongée par une jupe latérale 4 entourant une partie centrale 6 solidaire de la tête. La tête 2 comprend une face d'extrémité ou frontale 8 sur laquelle est apposé un motif tel qu'un logo ou une marque M. La partie centrale 6 est destinée à être reliée de manière classique au mouvement d'horlogerie par l'intermédiaire d'une tige de remontage ou de mise à l'heure. Dans l'exemple illustré, la partie centrale 6 est rapportée et fixée sur la tête 2. La partie centrale 6 comporte un tube 10 muni d'un disque 12 à une de ses extrémités. Typiquement, la partie centrale 6 est fixée par exemple par soudage, collage, sertissage ou tout autre moyen approprié dans un premier épaulement 14 ménagé dans la tête 2. La jupe latérale 4 est pourvue dans sa partie intérieure d'un taraudage 16 destiné à coopérer avec le filetage du tube chassé dans la carrure. Dans l'exemple illustré, le taraudage 16 est rapporté au moyen d'une bague 18 taraudée fixée à la paroi intérieure de la jupe 4. Là encore, tout moyen approprié peut être envisagé pour réaliser cette fixation, on citera à titre d'exemple le soudage, le collage, le sertissage etc.The crown 1 comprises a first part formed by an extended head 2 by a side skirt 4 surrounding a central part 6 secured to the head. Head 2 comprises an end or front face 8 on which is affixed a pattern such as a logo or an M mark. The central part 6 is intended to be connected so classic to the watch movement via a winding rod or time setting. In the example illustrated, the central part 6 is attached and fixed on the head 2. The central part 6 comprises a tube 10 provided with a disc 12 at one of its ends. Typically, the central part 6 is fixed for example by welding, bonding, crimping or any other appropriate means in a first shoulder 14 formed in the head 2. The side skirt 4 is provided in its inner part with a internal thread 16 intended to cooperate with the thread of the tube driven into the middle part. In the example illustrated, the internal thread 16 is attached by means of a ring 18 threaded fixed to the inner wall of the skirt 4. Again, any suitable means can be considered to achieve this fixing, we will mention by way of example welding, bonding, crimping etc.

Selon l'invention, la face d'extrémité 8 comprend un organe de support ou substrat 20 comportant une face avant 20a sur laquelle est apposé le motif M et une face arrière 20b. Le substrat 20 est monté mobile à rotation dans la tête 2 autour de l'axe de rotation A de la couronne 1 de manière que la face avant 20a soit visible depuis l'extérieur de la couronne. On voit à la figure 2 que la tête 2 comprend une ouverture 22 présentant trois diamètres étagés définissant respectivement le premier épaulement 14 et un deuxième épaulement 24 contre lequel appuie un rebord annulaire 26 du substrat 20. En outre il est prévu des moyens de freinage 28 qui agissent par frottement et qui sont agencés pour maintenir différentes orientations angulaires du substrat 20 par rapport à la carrure. Ainsi, lorsque la couronne 1 est vissée en butée sur le tube chassé sur la carrure, le motif M peut être aisément déplacé angulairement dans une position désirée contre la force de frottement engendrée par les moyens de freinage 28 et maintenu dans la position désirée. Le substrat 20 est ainsi serré axialement entre la surface avant 12a du disque 12 et la surface arrière 20b du substrat 20. De préférence, les dimensions respectives du substrat, notamment son épaisseur, et celles de la tête sont choisies de sorte que la face avant 20a se trouve à fleur de la surface frontale de la couronne 1 pour former ainsi une surface continue.According to the invention, the end face 8 comprises a support member or substrate 20 comprising a front face 20a on which is affixed the pattern M and a rear face 20b. The substrate 20 is mounted mobile in rotation in the head 2 around the axis of rotation A of the crown 1 so that the front face 20a is visible from outside the crown. We see in Figure 2 that the head 2 includes a opening 22 having three stepped diameters respectively defining the first shoulder 14 and a second shoulder 24 against which a flange rests annular 26 of the substrate 20. In addition, braking means 28 are provided which act by friction and which are arranged to maintain different orientations of the substrate 20 relative to the middle. So when crown 1 is screwed into abutment on the driven tube on the middle, the M pattern can be easily angularly moved to a desired position against the friction force generated by the braking means 28 and maintained in the desired position. The substrate 20 is thus clamped axially between the front surface 12a of the disc 12 and the rear surface 20b of the substrate 20. Preferably, the respective dimensions of the substrate, including its thickness, and those of the head are chosen so that the front face 20a is flush with the front surface of the crown 1 to form thus a continuous surface.

Selon un mode de réalisation préféré, les moyens de freinage 28 comprennent un élément annulaire élastique qui présente notamment une élasticité dans une direction parallèle à l'axe de rotation A. Typiquement l'élément annulaire peut être réalisé par un joint en matériau compressible naturel ou synthétique. L'élément annulaire 28 est disposé entre le disque 12 et la face arrière 20b du substrat dans une rainure annulaire 30 qui peut être ménagée, soit dans la face arrière 20b du substrat (figure 2), soit dans la face avant 12a du disque 12.According to a preferred embodiment, the braking means 28 comprise an elastic annular element which has in particular an elasticity in a direction parallel to the axis of rotation A. Typically the annular element can be produced by a seal made of natural or synthetic compressible material. The element annular 28 is disposed between the disc 12 and the rear face 20b of the substrate in a annular groove 30 which can be provided, either in the rear face 20b of the substrate (Figure 2), either in the front face 12a of the disc 12.

On notera que la force de freinage souhaitée peut être contrôlée en adaptant le taux de compression de l'élément annulaire lors de la fabrication.Note that the desired braking force can be controlled by adapting the compression ratio of the annular element during manufacture.

On notera également que l'utilisation d'un substrat rapporté sur la couronne permet au fabricant de couronnes d'avoir un stock de têtes/jupes latérales et de parties centrales et d'utiliser ces éléments avec des substrats portant des motifs différents ou d'autres éléments tels que des pierres précieuses ou analogues. Ce type de couronne permet également de marier aisément divers matériaux pour réaliser les divers éléments de celle-ci.It will also be noted that the use of a substrate attached to the crown allows the crown manufacturer to have a stock of side heads / skirts and central parts and to use these elements with substrates bearing patterns different or other elements such as precious stones or the like. This guy crown also allows to easily marry various materials to achieve the various elements of it.

On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme de métier peuvent être apportées au mode de réalisation décrit dans la présente description sans sortir du cadre de la présente invention définie par les revendications annexées. On pourra notamment prévoir d'utiliser un anneau à ressort ondulé en lieu et place du joint annulaire 28 dès lors qu'il possède une élasticité en compressibilité selon l'axe A. On pourrait également envisager de disposer les moyens de freinage entre la tranche du substrat 20 et la tête 2. Encore dans une autre variante, on pourrait envisager d'associer les moyens de freinage à des crans d'indexation pour positionner le substrat dans une pluralité de positions angulaires prédéfinies. Enfin, bien que le substrat 20 soit réalisé sous la forme d'une plaquette ou disque dans l'exemple illustré, il va de soi que d'autres formes de substrat 20 peuvent être envisagées dès lors que le substrat peut être mis en rotation relativement à la partie de la couronne vissée sur le tube chassé dans la carrure, à l'encontre de moyens de freinage.It will be understood that various obvious modifications and / or improvements for those skilled in the art can be brought to the embodiment described in the present description without departing from the scope of the present invention defined by appended claims. We could in particular plan to use a spring ring corrugated in place of the annular seal 28 as soon as it has elasticity in compressibility along axis A. We could also consider placing the braking means between the edge of the substrate 20 and the head 2. Still in a another variant, one could consider associating the braking means with notches indexing to position the substrate in a plurality of angular positions predefined. Finally, although the substrate 20 is produced in the form of a wafer or disc in the example illustrated, it goes without saying that other forms of substrate 20 can be considered as soon as the substrate can be rotated relative to the part of the crown screwed onto the tube driven into the middle, at against braking means.
