Winding device, in particular for a clock barrel, provided with disconnection means

A winding device (1) for a barrel (2) provided with a spring, comprising:

• a ratchet (3) mounted on a rotary winding shaft (5), the rotary winding shaft (5) being a winding shaft of the barrel (2), the rotation of which about a winding axis coils the barrel (2);
• a winding gear train (4) meshing with the ratchet (3), the rotation of the winding gear train (4) causing the rotation of the ratchet (3) and that of the rotary winding shaft (5) by applying a torque to the ratchet (3);
• and
• disconnecting means (10) for disconnecting the ratchet (3) and the rotary winding shaft (5), the disconnection means (10) being arranged on the ratchet (3) and on the rotary winding shaft (5), and disconnecting the ratchet (3) and the rotary winding shaft (5) when the torque applied to the ratchet (3) substantially exceeds a threshold value, when the barrel (2) is fully coiled,
• wherein the disconnection means (10) comprise a plurality of flexible pawls (15), and
• wherein the ratchet (3) comprises a hub (7) forming a circular ring around the rotary winding shaft (5) and on which the flexible pawls (15) are arranged, the flexible pawls (15) extending radially from the hub (7) towards the winding axis.
