Abstract

Spiral plan destiné à être monté sur l'axe de balancier d'un organe régulateur de montre mécanique, le spiral étant formé d'une lame de rigidité sensiblement constante,
le spiral comportant :
plusieurs spires internes dans lesquelles la distance (ρ) entre chaque point et le centre de rotation varie de façon sensiblement linéaire en fonction de la position angulaire (θ) du point lorsque le spiral est au repos;
une spire externe dans lesquelles la distance (r) entre chaque point et le centre de rotation est une fonction non linéaire de la position angulaire (θ) du point lorsque le spiral est au repos;
ladite fonction non linéaire ayant pour effet de réduire la pression latérale exercée par le spiral sur ledit axe de balancier lorsque le spiral est monté sur cet axe et/ou ayant pour effet de compenser le retard dû à l'échappement aux petites amplitudes d'oscillation.
