Mechanical spring lift for moving spring of clockwork of wrist-watch, has ratchet arm forming ratchets together with teeth of ratchet wheel, where ratchet lever together with ratchet arms is made of resilient material
The lift (1) has an eccentric mass (2) pivotable around a hinge (3) and comprising a centre of mass that is radially opposite to an axis of the hinge. A gear unit converts pivotable movement of the mass to rotation movement that lifts a main spring. The gear has an eccentric (7) connected with the mass, and a ratchet lever (12) with a ratchet arm (12.1). The eccentric is rotated around an eccentric axis (6) during pivoting of the mass. Another ratchet arm (12.3) forms ratchets together with teeth (10) of a ratchet wheel (9). The lever together with the arms is made of resilient material.
