Abstract

A timepiece (1) contains a movement (2), topped by a dial (3) and housed in a casing (4) of a watch case. A crystal (5) is located over at least a portion of its periphery against the upper edge (6) of the casing. The edge (6) has a surface inclined (7) toward the inside of the case and defines with the opposite surface of the periphery of the crystal and with the outer edge of a riser (8) placed on the circumference of the dial (3) a housing in which a gasket (9) is deformably held.

Description

La présente invention concerne les pièces d'horlogerie, et elle se rapporte plus précisément aux pièces élégantes dans lesquelles la glace, amovible, vient s'appuyer au moins sur une portion de sa périphérie, directement contre le bord supérieur de la carrure.The present invention relates to timepieces, and it relates more precisely to elegant pieces in which the removable glass comes to bear at least on a portion of its periphery, directly against the upper edge of the middle part.

Dans ce type de constructions, il n'a jusqu'ici pas été possible d'utiliser des cadrans de très grande surface, pouvant s'étendre pratiquement jusqu'au bord de la carrure, notamment en raison de l'encombrement des logements qu'il faut prévoir à cet endroit pour un joint d'étanchéité. Pour masquer ce joint, il est alors nécessaire d'avoir recours à des zones métallisées de largeur correspondante sur la face inférieure de la glace qui alourdissent la ligne de la pièce.In this type of construction, it has so far not been possible to use dials of very large area, which can extend practically to the edge of the middle part, in particular because of the size of the housings which provision must be made here for a seal. To mask this joint, it is then necessary to have recourse to metallized zones of corresponding width on the lower face of the glass which weigh down the line of the part.

L'invention, qui propose justement des moyens pour remédier à cet invonvénient, sera bien comprise à la lecture de la description suivante faite en référence au dessin joint qui en représente, en coupe partielle, un mode de réalisation particulier.The invention, which precisely proposes means to remedy this drawback, will be clearly understood on reading the following description made with reference to the attached drawing which represents, in partial section, a particular embodiment.

La pièce d'horlogerie généralement référencée 1 dans le dessin comprend notamment un mouvement 2 surmonté d'un cadran 3 et logé dans la carrure 4 d'une boîte de montre. Une glace 5 est appliquée contre le bord supérieur 6 de la carrure 4. Ce bord supérieur 6 présente une surface 7 inclinée vers l'intérieur de la boîte et définissant avec la surface en regard de la glace 5 et le bord extérieur d'un réhaut 8 placé sur le pourtour du cadran 3 un logement à section triangulaire pour le joint d'étanchéité 9.The timepiece generally referenced 1 in the drawing comprises in particular a movement 2 surmounted by a dial 3 and housed in the middle part 4 of a watch case. A lens 5 is applied against the upper edge 6 of the middle part. This upper edge 6 has a surface 7 inclined towards the inside of the case and defining with the facing surface of the lens 5 and the outer edge of a flange 8 placed on the periphery of the dial 3 a triangular section housing for the seal 9.

Pour masquer le joint d'étanchéité 9, on a prévu une couche métallisée 10 qui s'étend jusqu'au-delà du réhaut 8 et, dont la largeur peut alors être très faible, de l'ordre de 1,5 mm ou moins par exemple. Cette largeur sera d'autant plus faible que la surface inclinée 7 s'étendra sur une plus grand largeur du bord 6. Dans le mode de réalisation du dessin, elle couvre sensiblement toute cette largeur, son inclinaison étant de l'ordre de 45° environ.To mask the seal 9, a metallized layer 10 is provided which extends beyond the flange 8 and, the width of which can then be very small, of the order of 1.5 mm or less for example. This width will be all the smaller as the inclined surface 7 extends over a greater width of the edge 6. In the embodiment of the drawing, it covers substantially this entire width, its inclination being of the order of 45 ° about.

Dans le dessin, on a représenté également un dispositif particulier pour maintenir la glace 5 contre la carrure 4. Ce dispositif comprend des éléments de liaison 11 dont la première extrémité, munie par exemple d'une tête 12 et traversant la glace 5, assure la retenue de celle-ci. L'autre extrémité des éléments de liaison 11 est assujetti du manière amovible dans des passages 13 de la carrure 4, par exemple au moyen de vis latérales 14. Selon une caractéristique importante de la construction, qui permet justement d'utiliser des cadrans de grand diamètre, les éléments 11 traversent également des passages appropriés 15 du cadran 3. Une pièce tubulaire 16 qui retient des joints d'étanchéité 17 et 18 entoure le corps des éléments 11 à leur débouché de la glace.In the drawing, there is also shown a particular device for holding the crystal 5 against the middle part 4. This device comprises connecting elements 11, the first end of which, for example provided with a head 12 and passing through the crystal 5, ensures the restraint of it. The other end of the connecting elements 11 is removably secured in passages 13 of the middle part 4, for example by means of lateral screws 14. According to an important characteristic of the construction, which precisely makes it possible to use large dials diameter, the elements 11 also pass through appropriate passages 15 of the dial 3. A tubular part 16 which retains seals 17 and 18 surrounds the body of the elements 11 at their outlet from the ice.

Bien qu'elle ait été décrite en relation avec l'un de ses modes de réalisation particuliers, la présente invention ne s'y trouve nullement limitée, mais elle est au contraire susceptible de faire l'objet de nombreuses modifications et variantes qui apparaîtront à l'homme de l'art.Although it has been described in relation to one of its particular embodiments, the present invention is in no way limited thereto, but is on the contrary liable to be the subject of numerous modifications and variants which will appear one skilled in the art.

En particulier, le logement pour le joint d'étanchéité 9 pourra présenter une section autre que triangulaire, notamment si la surface inclinée 7 ne s'étend pas sur toute la largeur du bord 6, ou si elle présente plusieurs inclinaisons différentes. De la -même manière, le logement tel que défini par la glace 5, le bord supérieur 6 de la carrure 4 et le réhaut 8 peut ne pas s'étendre sur toute la périphérie de la glace, mais seulement par exemple sur deux côtés opposés d'une boîte rectangulaire, les deux autres côtés étant par exemple occupés par des glissières, des griffes de fixation de la glace, etc.... Il est clair également que les éléments de liaison 11 pourraient aisément être remplacés par tout organe d'assemblage approprié.In particular, the housing for the seal 9 may have a section other than triangular, in particular if the inclined surface 7 does not extend over the entire width of edge 6, or if it has several different inclinations. In the same way, the housing as defined by the glass 5, the upper edge 6 of the middle part 4 and the flange 8 may not extend over the entire periphery of the glass, but only for example on two opposite sides of a rectangular box, the other two sides being for example occupied by slides, claws for fixing the glass, etc. It is also clear that the connecting elements 11 could easily be replaced by any member for proper assembly.
