Definitions
- the invention relates to a bezel for a timepiece.
- the element is for example a rotating bezel
- the index makes it possible, for example, to indicate a reference position for the measurement, by the diver, of his immersion time at sea. To do this, the diver turns the bezel so as to align the index with the minute hand. This position then becomes the reference for measuring the elapsed time.
- One of the main efficiency criteria of a diver's watch must be the readability of the time and the index during the immersion phase.
- a known solution consists in covering the index of the bezel, as well as the hands of the watch, with a phosphorescent material. This makes the index and hands visible in low light conditions, typically a few meters underwater.
- a diver's watch is for example described in the patent application FR 1 572 837 A .
- a drawback of this solution is that it makes it necessary to change the complete bezel once the phosphorescent material has been exhausted.
- such a solution generally requires placing the indications on the surface of the bezel, which exposes them to shocks and friction and damages them irreparably.
- the object of the invention is to overcome the drawbacks of the prior art by proposing to provide a bezel system fitted with a luminescent timer which is simple to mount, waterproof and safe.
- the invention relates to a bezel which comprises the characteristics mentioned in independent claim 1.
- the invention further relates to a timepiece comprising a case comprising a middle part closed by a back and a crystal and provided with a bezel, and a bezel according to one of the preceding claims.
- THE figures 1 and 2 illustrate a bezel 1 according to the invention, the bezel 1 being arranged to be mounted on a timepiece which comprises a case closed by a bottom and a crystal.
- the bezel 1 is a part of annular shape and comprises an upper face visible by the user and a lower face in direct or indirect contact with the watch case.
- This bezel 1 may be made of a metallic, composite or even ceramic material, or even of plastic material.
- the bezel 1 can be mounted rotating or not at the level of the caseband.
- a spring-notching assembly or snap-fastening system is arranged in the case of a rotating bezel.
- This spring-notch assembly comprises spring means and a toothed element.
- One of the elements of the spring-notching assembly will be angularly secured to the caseband while the other will be angularly secured to the bezel 1 so as to allow the angular indexing of the bezel with respect to the caseband.
- the timepiece For mounting the bezel 1, the timepiece comprises in known manner a middle part in which a shoulder is arranged, this shoulder being defined by a side wall and a base.
- This shoulder serves as a housing for the bezel.
- the side wall includes a protrusion extending over the entire perimeter of the side wall. This protrusion makes it possible to define, in cooperation with the base and the wall, a retaining groove. This retaining groove allows, during force assembly of the bezel, that the latter is inserted therein and is maintained.
- the bezel 1 has a groove 2 at the level of the upper face 1a, this groove 2 also being annular, that is to say extending along the upper face 1a, and comprising a bottom 20 and two walls 21, 22.
- the bezel 1 acts as a housing for a ring of luminescent material 3 which is arranged on the bottom 20, and for a second ring of mineral material 4 surmounting the ring of luminescent material 3 and occupying the remaining volume of the groove 2.
- bezel 1 further comprises a timer element.
- This timer element is in the form of a ring of luminescent material 3 which comprises a timer element 30 allowing an indication of the minutes, and whose dimensions allow it to be placed in the bottom 20 of the groove 2 of the bezel 1 as visible at the figure 2 .
- This ring of luminescent material 3 can be made of a plastic or metallic or organic material such as wood or of a material crystalline like sapphire or ruby or ceramic. Timer indices are then produced in relief, that is to say in extra thickness, on the surface of the ring 3.
- the ring of luminescent material 3 is in the form of a ring of circular or trapezoidal section as illustrated in figure 2 .
- the timer marking on bezel 1 is produced in the form of metallizations forming indices.
- the second ring 4 is made of a transparent mineral material so as to be able to observe the timer through the second ring 4.
- the second ring 4 is therefore mounted in the groove 2, above the luminescent material ring 3
- the second ring 4 is in the form of an annular ring of rectangular section and whose dimensions allow it to be placed in the groove 2 so that the latter is flush with the upper surface of the bezel 1.
- the mineral material forming the second ring is chosen from: glass, sapphire, ruby, ceramic.
- the groove comprises, on each of the walls 21, 22, a groove 6, 6' which is arranged to receive a seal 5, 5', of O-ring shape, so as to seal the groove and prevent dust or liquids from being deposited on the luminescent material ring 3.
- the height of the grooves is similar to the height of the second ring 4, which makes it possible to have a thicker/higher seal 5 and thus better sealing.
- the second ring 4 also has chamfers at the upper and lower edges to facilitate insertion and avoid damaging the seal.
- the upper part of the groove 5, 5' is slightly chamfered so as not to pinch the seal and damage it when inserting the second ring 4.
- each joint 5, 5 is then placed in a corresponding groove 6, 6'.
- the second ring 4 is inserted by force into the groove 2 over the luminescent material ring 3.

Description
L'invention concerne une lunette pour pièce d'horlogerie.The invention relates to a bezel for a timepiece.
Dans le domaine des montres comprenant une boîte de montre munie d'une carrure, il est connu de prévoir sur la carrure un élément muni d'au moins un index lumineux. Dans le cas d'une montre de plongée l'élément est par exemple une lunette tournante, et l'index permet par exemple d'indiquer une position de référence pour la mesure, par le plongeur, de son temps d'immersion en mer. Pour ce faire, le plongeur tourne la lunette de manière à aligner l'index avec l'aiguille des minutes. Cette position devient alors la référence pour mesurer le temps écoulé. Un des critères d'efficacité principaux d'une montre de plongée doit être la lisibilité de l'heure et de l'index pendant la phase d'immersion.In the field of watches comprising a watch case provided with a middle part, it is known to provide on the middle part an element provided with at least one luminous index. In the case of a diver's watch, the element is for example a rotating bezel, and the index makes it possible, for example, to indicate a reference position for the measurement, by the diver, of his immersion time at sea. To do this, the diver turns the bezel so as to align the index with the minute hand. This position then becomes the reference for measuring the elapsed time. One of the main efficiency criteria of a diver's watch must be the readability of the time and the index during the immersion phase.
Afin de répondre à cette contrainte, une solution connue consiste à recouvrir l'index de la lunette, ainsi que les aiguilles de la montre, d'une matière phosphorescente. Ceci permet de rendre l'index et les aiguilles visibles dans des conditions de faible luminosité, typiquement à quelques mètres sous l'eau. Une telle montre de plongée est par exemple décrite dans la demande de brevet
L'invention a pour but de pallier les inconvénients de l'art antérieur en proposant de fournir un système de lunette muni d'une minuterie luminescente qui soit simple à monter, étanche et sûre.The object of the invention is to overcome the drawbacks of the prior art by proposing to provide a bezel system fitted with a luminescent timer which is simple to mount, waterproof and safe.
A cet effet, l'invention concerne une lunette qui comprend les caractéristiques mentionnées dans la revendication indépendante 1.To this end, the invention relates to a bezel which comprises the characteristics mentioned in

La lunette 1 peut être montée tournante ou non au niveau de la carrure. Dans le cas d'une lunette tournante, un ensemble ressort-crantage ou système à encliquetage est agencé. Cet ensemble ressort-crantage comprend des moyens ressorts et un élément denté. Un des éléments de l'ensemble ressort-crantage sera angulairement solidaire de la carrure alors que l'autre sera angulairement solidaire de la lunette 1 de sorte à permettre l'indexation angulaire de la lunette par rapport à la carrure.The
Pour le montage de la lunette 1, la pièce d'horlogerie comprend de manière connue une carrure dans laquelle un épaulement est agencé, cet épaulement étant défini par une paroi latérale et une base. Cet épaulement sert de logement pour la lunette. En général, la paroi latérale comprend une excroissance s'étendant sur l'intégralité du périmètre de la paroi latérale. Cette excroissance permet de définir, en coopération avec la base et la paroi, une gorge de maintien. Cette gorge de maintien permet, lors de l'assemblage à force de la lunette, que celle-ci s'y insère et soit maintenu.For mounting the
Selon l'invention, la lunette 1 présente une rainure 2 au niveau de la face supérieure 1a, cette rainure 2 étant également annulaire c'est à dire s'étendant le long de la face supérieure 1a, et comprenant un fond 20 et deux parois 21, 22.According to the invention, the
Avantageusement, la lunette 1 fait office de logement pour une bague en matière luminescente 3 qui est disposée sur le fond 20, et pour une deuxième bague en matériau minéral 4 surmontant la bague en matière luminescente 3 et occupant le volume restant de la rainure 2.Advantageously, the
Selon l'invention, la lunette 1 comprend en outre un élément de minuterie. Cet élément de minuterie se présente sous la forme bague en matière luminescente 3 qui comprend un élément de minuterie 30 permettant une indication des minutes, et dont les dimensions lui permettent d'être placée dans le fond 20 de la rainure 2 de la lunette 1 comme visible à la
Selon un mode de réalisation avantageux, le marquage de minuterie sur la lunette 1 est réalisé sous forme de métallisations formant des indices.

Avantageusement, la deuxième bague 4 est réalisée en un matériau minéral transparent de manière à pouvoir observer la minuterie au travers de la deuxième bague 4. La deuxième bague 4 est donc montée dans la rainure 2, au-dessus de la bague en matière luminescente 3. La deuxième bague 4 se présente sous la forme d'une bague annulaire de section rectangulaire et dont les dimensions lui permettent d'être placée dans la rainure 2 de sorte que celle-ci affleure avec la surface supérieure de la lunette 1.Advantageously, the second ring 4 is made of a transparent mineral material so as to be able to observe the timer through the second ring 4. The second ring 4 is therefore mounted in the
Le matériau minéral formant la deuxième bague est choisi parmi : le verre, le saphir, rubis, la céramique.The mineral material forming the second ring is chosen from: glass, sapphire, ruby, ceramic.
Selon l'invention, la rainure comprend, sur chacune des parois 21, 22, un sillon 6, 6' qui est agencé pour recevoir un joint 5, 5', de forme torique, de manière à assurer l'étanchéité de la rainure et éviter que des poussières ou liquides viennent se déposer sur la bague en matière luminescente 3. La hauteur des sillons est similaire à la hauteur de la deuxième bague 4, ce qui permet d'avoir un joint 5 plus épais/plus haut et ainsi une meilleure étanchéité. La deuxième bague 4 présente également des chanfreins au niveau des arrêtes supérieure et inférieure pour faciliter l'insertion et éviter d'abimer le joint.According to the invention, the groove comprises, on each of the
