Abstract

The hand comprises a lengthy body (1), made from sapphire, facetted at (2) and having, on its posterior face, a metallised layer (3) and a layer of fluorescent material (4) which are visible by transparency. This lengthy body (1) is tightly fitted, by its end (1b), into a notch (6) in a metal mounting (5), facetted at (7) and provided with a pipe (8) intended to be fitted onto the member of the timepiece driving the hand. <IMAGE>

Description

La présente invention a pour objet une aiguille pour pièce d'horlogerie.The present invention relates to a needle for a timepiece.

Le but de la présente invention est de fournir un moyen permettant la réalisation d'aiguilles pour pièces d'horlogerie qui soient, dans leur majeure partie au moins, en pierre précieuse, alors même que les possibilités d'usinage de ce matériau sont restreintes et qu'il résiste mal aux contraintes mécaniques, telles celles produites par le montage de l'aiguille sur l'organe de la pièce d'horlogerie qui l'entraîne.The object of the present invention is to provide a means enabling the production of needles for timepieces which are, for the most part at least, made of precious stone, even though the possibilities for machining this material are limited and that it has poor resistance to mechanical stresses, such as those produced by mounting the needle on the organ of the timepiece which drives it.

Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.

  • La fig. 1 est une vue en perspective d'une aiguille de minutes pour montre.
  • La fig. 2 en est une vue en plan, et
  • La fig. 3 en est une vue en élévation.
The drawing represents, by way of example, an embodiment of the subject of the invention.
  • Fig. 1 is a perspective view of a minute hand for a watch.
  • Fig. 2 is a plan view thereof, and
  • Fig. 3 is an elevational view thereof.

L'aiguille représentée comprend un corps longiforme 1, en saphir, se terminant, à une extrémité, par une partie pointue 1a et dont les bords de la face antérieure sont facettés en 2. La face postérieure de ce corps longiforme est revêtue d'une couche métallisée 3, visible par transparence à travers le saphir, laissant en son centre une zone épargnée 4 revêtue de matière luminescente, également visible par transparence.The needle shown comprises a elongated body 1, made of sapphire, ending at one end with a pointed part 1 a and the edges of the front face of which are faceted at 2. The rear face of this elongated body is coated with a metallized layer 3, visible by transparency through the sapphire, leaving in its center a spared area 4 coated with luminescent material, also visible by transparency.

Le corps longiforme 1 est rapporté, par son extrémité opposée à sa pointe 1a, désignée par 1b, à une monture métallique 5 dont une extrémité 5a est pointue et dont l'extrémité opposée présente une encoche transversale 6 dans laquelle l'extrémité du corps longiforme 1 opposée à son extrémité pointue 1a, désignée par 1b, est engagée à frottement dur. On pourra prévoir d'interposer de la colle entre l'extrémité 1b du corps longiforme et les parois de l'encoche 6 de la monture 5. La face antérieure de cette monture est facettée en 7.The elongated body 1 is attached, by its end opposite to its point 1 a , designated by 1 b , to a metal frame 5, one end 5 a of which is pointed and the opposite end of which has a transverse notch 6 in which the end 1 of the elongated body opposite its pointed end 1a, designated by 1b, is engaged as a tight fit. Provision may be made for interposing glue between the end 1b of the elongated body and the walls of the notch 6 of the frame 5. The front face of this frame is faceted at 7.

Enfin la monture 5 porte un canon 8 à l'aide duquel l'aiguille se fixe sur la chaussée de la montre qui l'entraîne. Il est à remarquer que, pour les aiguilles d'heures, la monture sera percée d'un trou traversant situé dans le prolongement de son canon.Finally the frame 5 carries a barrel 8 with the help of which the needle is fixed on the pavement of the watch which drives it. It should be noted that, for the hour hands, the frame will be pierced with a through hole located in the extension of its barrel.

Grâce à la présente disposition, la réalisation de l'aiguille ne pose pas de problème d'usinage, quand bien même sa plus grande partie est en saphir, l'usinage du corps longiforme 1 étant facile à exécuter. De plus, les contraintes que produit le montage de l'aiguille sur l'organe de la montre qui l'entraîne sont absorbées par la monture métallique, apte à les supporter.Thanks to this arrangement, the production of the needle does not pose a machining problem, even though its largest part is made of sapphire, the machining of the elongated body 1 being easy to execute. In addition, the stresses produced by the mounting of the hand on the organ of the watch which drives it are absorbed by the metal frame, capable of withstanding them.

En variante, le corps longiforme pourra ne pas être réalisé en saphir mais en toute pierre précieuse, naturelle ou synthétique.Alternatively, the elongated body may not be made of sapphire but of any precious stone, natural or synthetic.

Le facettage de la face antérieure du corps en pierre précieuse et de la monture pourra être différent de celui décrit et représenté, ou même ne pas exister.The faceting of the anterior face of the precious stone body and of the frame may be different from that described and shown, or even not exist.

La couche métallisée pourra ne pas présenter de zone centrale épargnée, l'aiguille étant alors dépourvue de matière fluorescente. Cette couche métallisée pourra être de couleurs diverses. Elle pourra être apposée par tous les moyens connus tels que l'évaporation sous vide, le dépôt par voie chimique ou autre.The metallized layer may not have a spared central zone, the needle then being devoid of fluorescent material. This metallized layer may be of various colors. It can be affixed by all known means such as vacuum evaporation, chemical or other deposition.

En variante également, et spécialement dans le cas des aiguilles de minutes dont le trou de la monture n'est pas obligatoirement traversant, la monture pourra être ornée d'une pierre sertie, par exemple un diamant.Alternatively also, and especially in the case of minute hands whose hole in the frame is not necessarily through, the frame may be adorned with a set stone, for example a diamond.
