Abstract
Lever (6) comprising at least a first element (61) for guiding in rotation of a first wheel (1), at least one friction element (62) which is designed to co-operate with an at least substantially cylindrical portion (10c) of the first wheel, and at least one resilient element (63), which is designed to return resiliently the at least one friction element to a state of co-operation with the said portion of the first wheel, notably in contact with the said portion of the first wheel.
Claims25
Horological coupling device, comprising:
- a lever, and
- a first wheel guided in rotation in the lever,
- wherein the lever comprises:
- at least one friction element which co-operates with an at least substantially cylindrical portion of the first wheel, and
- at least one resilient element, which returns resiliently the at least one friction element to a state of co-operation with said portion of the first wheel, so as to create a resistive torque between the lever and the first wheel that opposes a rotation of the first wheel,
- wherein the coupling device is adapted to be mounted in a horology movement.
