Abstract
The oscillating weight (2) is for automatically winding a timepiece movement; it pivots off-center relative to the center of the movement and is made of a single heavy material. The weight (2) is carried by a shock absorber (1) that takes the form of a plate (4), one end of which is secured to the weight and the other end of which is secured to a tube (5) arranged to rotate about an arbour (6) forming the axis of rotation of the weight.
Claims4
An oscillating weight for automatically winding a timepiece movement, wherein the oscillating weight pivots off-centre relative to a centre of the timepiece movement and is made of a single heavy material, wherein the oscillating weight is carried by a first plate acting as a shock absorber, wherein one end of the first plate is secured to the oscillating weight, and the other end of the first plate is fixed to a tube arranged to rotate about an arbour forming an axis of rotation of the oscillating weight,
- wherein stop means are implemented to limit an axial shake of the oscillating weight in the event of any shock, and
- wherein the stop means consist of a groove that is made in the oscillating weight and penetrated by a retaining tongue forming an end of a banking bridge.
