Title: The Innovations of Guy Dubois-Ferrière

Introduction

Guy Dubois-Ferrière is a notable inventor based in St-Cergues, France. He has made significant contributions to the field of mechanical engineering, particularly in the design of display mechanisms and chronograph systems. With a total of two patents to his name, Dubois-Ferrière continues to push the boundaries of innovation.

Latest Patents

His latest patents include a "Display Mechanism with Zero Reset Function." This invention features a wheel that carries a first wheel and a snail-shaped cam. The mechanism operates in two states: an active first state where the first wheel is driven in rotation by a driving wheel, and a zero reset second state that allows the first wheel to return to a predefined position. The design incorporates a feeler-spindle that interacts with the cam's perimeter, ensuring a return force that aids in resetting the first wheel.

Another significant patent is the "Coupling System for a Chronograph." This system includes an input wheel driven by a drive member and an output wheel that drives at least one display member. The intermediate wheel can switch between a coupled state, where it connects the input and output wheels, and an uncoupled state, breaking the connection. This innovative design also features friction wheels and safety wheels that enhance the reliability of the chronograph mechanism.
