Abstract

Spiral pour mouvement d'horlogerie mécanique caractérisé par le fait qu'il est muni d'une courbe extérieure périphérique située dans le plan du spiral et que la rigidité de cette courbe est telle que la partie centrale de l'ensemble spiral-courbe ainsi constitué se développe concentriquement lors de ses oscillations.

Figure imgaf001
Spiral for mechanical clockwork characterized in that it is provided with a peripheral outer curve located in the plane of the spiral and that the rigidity of this curve is such that the central portion of the spiral-curve assembly thus constituted develops concentrically during its oscillations.
