Clockwork with automatic winding mechanism

Abstract

A clockwork mechanism with automatic winding, in which a hammer (2) is mounted on a pivot bearing (21) arranged off-center and is pivotable about a zero position, back and forth between two extreme positions, wherein the hammer (2) is operatively connected to a winding gear (5) which converts a pivoting movement of the hammer (2) into a movement usable for winding a mainspring of the clockwork, wherein a damping device extracts energy from the hammer (2) when approaching an extreme position, temporarily stores a portion of the energy extracted from the hammer (2) and subsequently feeds it back to the hammer (2), wherein the hammer (2) is operatively connected to a restoring spring (3) generating a restoring force, characterized in that the restoring spring (3), designed as a bending bar spring, is attached to a spring head (31) arranged off-center of the clockwork, which is arranged opposite the pivot bearing (21) with respect to the center of the clockwork.wherein the free end of the return spring (3) opposite the spring head (31) is operatively connected to the hammer (2) in the area of ​​the pivot bearing (21) in a restoring force.
