[origin: EP1369886A1] The mechanical spring command has a toothed wheel (2) which rotates with a spring, moving between two angular positions. A smaller gear wheel (3) moves between two angular positions. The main toothed wheel has a retractable section (10) forming a constant path. Four teeth on the retractable section have the same constant path as the primitive section.
