Abstract
A disengageable winding device (1) for a barrel (2) provided with a spring, comprising a ratchet (3) mounted on a winding arbor such that it is rigidly connected thereto, the winding arbor being an arbor for winding the barrel (2), the rotation of which winds up the barrel (2), and a winding gear train (40) meshing with the ratchet (3), the rotation of the winding gear train (40) driving the rotation of the ratchet (3) and that of the winding arbor.
Claims10
The disengageable winding device (10) for a barrel (2) provided with a spring, comprising:
- a ratchet (3) mounted on a winding arbor and rigidly connected thereto, the winding arbor being an arbor for winding the barrel (2), the rotation of which winds up the barrel (2),
- a winding gear train (40) meshing with the ratchet (3), the rotation of the winding gear train (40) driving the rotation of the ratchet (3) and that of the winding arbor, and
- an actuating wheel set (31) for driving the winding gear train (40) by applying a torque to the winding gear train (40), the actuating wheel set (31) meshing with the winding gear train (40) in an engaged position, the winding gear train (40) being mounted to slide about a rotary arbor (26) out of the engaged position when the torque applied to the winding gear train (40) is substantially greater than a threshold value when the barrel (2) is fully wound up.
