Description
<B>Aiguille pour pièce d'horlogerie.</B> La présente invention a pour objet une aiguille pour une pièce d'horlogerie, telle que montre, pendule, pendulette, cette aiguille étant caractérisée en ce que sa tête présente un évidement annulaire à sa face inférieure.
Le dessin annexé représente, à titre d'exemple, deux formes d'exécution de l'ai guille suivant l'invention.
La fi-. 1 montre en coupe une aiguille de minute sans canon.
La fig. 2- est une vue en plan de dessus de l'aiguille montrée à la fig. 1.
La fig. 3 montre en coupe une aiguille d'heure à canon.
Jusqu'à présent, les aiguilles de minutes sans canon, dont. la tête a une épaisseur totale comprise entre 0,25 et 0,35 mm, de vaient être équarries ou retouchées pour être ajustées sur les chaussées.
L'invention a pour but de supprimer cet inconvénient et cette perte de temps.
On voit aux fig. 1 et 2 une aiguille de mi nute sans canon, composée d'une tête 1 et d'une partie allongée 2 formant index. La tête 1. présente un évidement annulaire 3 à sa face inférieure, avec une petite goutte des tinée à maintenir la -hauteur égale à l'épais seur de tête des aiguilles usuelles. Cette tête évidée a l'avantage de procurer plus d'élas ticité, ce qui permet, lors du posage de l'ai guille, de fixer aisément et sans retouche l'ai guille de minute sur la chaussée. Cette élasti cité compense les petites différences de tolé rance dans le diamètre des chaussées et dans les trous d'aiguille.3.
On voit en fig. 3 une aiguille d'heure pré sentant, comme celle de minute déjà décrite, une tête 1, munie d'un évidement annulaire 3 à, sa face inférieure, et une partie allongée 2. En outre, la partie intérieure de la tête 1 se prolonge ici en un canon J.
Pratiquement, pour l'aiguille d'heure, l'évidement annulaire de la tête est moins im portant, et l'invention offre vraiment tous ses avantages pour l'aiguille de minute.
<B> Needle for a timepiece. </B> The present invention relates to a hand for a timepiece, such as a watch, pendulum, clock, this hand being characterized in that its head has an annular recess on its underside.
The appended drawing represents, by way of example, two embodiments of the guille according to the invention.
The fi-. 1 shows in section a minute hand without a barrel.
Fig. 2- is a top plan view of the needle shown in FIG. 1.
Fig. 3 shows a sectional view of a barrel hour hand.
Until now, minute hands without a barrel, including. the head has a total thickness between 0.25 and 0.35 mm, to be squared or retouched to be fitted on the roadways.
The object of the invention is to eliminate this drawback and this waste of time.
We see in fig. 1 and 2 a needle without barrel, composed of a head 1 and an elongated part 2 forming an index. The head 1. has an annular recess 3 on its underside, with a small drop of tines to keep the -height equal to the head thickness of the usual needles. This hollowed-out head has the advantage of providing more elasticity, which makes it possible, when installing the needle, to easily fix the minute needle to the roadway without retouching it. This elasticity compensates for small differences in tolerance in the diameter of the pavements and in the needle holes. 3.
We see in fig. 3 an hour hand having, like the minute hand already described, a head 1, provided with an annular recess 3 on its underside, and an elongated part 2. In addition, the inner part of the head 1 is here extends into a J.
In practice, for the hour hand, the annular recess in the head is less important, and the invention really offers all of its advantages for the minute hand.
