Abstract
The oscillating mass able to be fixed to a frame (1) pivoted on the exterior of a timepiece movement has toothing kinematically connected to the ratchet of a barrel of the timepiece movement. This oscillating mass has, on the one hand, a mount (4) which is annular or is in the form of an annular sector and is able to be fixed to the frame (1) and, on the other hand, a central part (7) located mainly or exclusively in one half of the surface delimited by the mount (4).
Claims21
An automatic winding timepiece movement comprising:
- a frame (1, 2) pivotably fixable on and above a radially outermost peripheral part of an exterior of a timepiece movement, the frame having toothing (1b) that meshes with a kinematic link connecting the toothing (1b) to a ratchet of a barrel of the timepiece movement;
- and
- an oscillating mass (4, 6, 7) fixed to the frame (1) such that all of the oscillating mass is pivoted outside of and above all internal gearing components of the timepiece movement,
- wherein the oscillating mass is comprised of i) a mount (4) fixed to said frame (1) and ii) a central part (7) located mainly or exclusively in one half of a surface delimited by said mount (4), and located overhanging a part of the dial (9) and a part of the internal gearing components of the timepiece movement.
An oscillating mass fixable to a frame (1) pivoted on a radially outermost exterior of a timepiece movement and having toothing kinematically connected to the ratchet of a barrel of said timepiece movement, the oscillating mass comprising:
- a mount (4) which is annular or has an annular sector and is able to be fixed to said frame (1) and,
- a central part (7) located mainly or exclusively in one half of the surface delimited by said mount (4),
- wherein the oscillating mass is fixed to the frame (1) of the timepiece movement, and all of both the frame and the oscillating mass are pivoted outside and above all internal gearing components of the timepiece movement, and wherein the oscillating mass is located overhanging a part of a dial (9) of the timepiece.
An automatic winding timepiece movement comprising:
- a ball bearing having an inner ring and an outer ring (2), a lower surface of the outer ring being fixable to an upper surface of a plate (3) that is a radially outermost peripheral portion of a timepiece movement, the timepiece movement further comprising a dial (9), hands (10, 11), and an automatic winding mechanism with internal gearing components including a winding gear;
- a frame (1) mounted to and above the inner ring of the ball bearing such that, via the ball bearing, the frame is pivotably fixed above the upper surface of the plate (3), the frame having toothing (1b) that meshes with a kinematic link connecting the toothing (1b) to a ratchet of a barrel of the timepiece movement, a radially inside perimeter (1a) of the frame surrounding a radially outside perimeter of the dial (9);
- an oscillating mass (4, 6, 7) located above the dial (9) and fixed to the frame (1) pivoted such that all of the oscillating mass is pivoted outside and above all the internal gearing components of the timepiece movement,
- wherein the oscillating mass is comprised of i) an annular mount (4) fixed to an upper surface of said frame (1) and ii) a central part (7) located mainly or exclusively in one half of a surface delimited by said mount (4) and is located overhanging a part of the dial (9) and a part of the internal gearing components of the timepiece movement.
