Abstract
Spring (10) for clock mechanism, the spring comprising a body (11) extending between a first end (12) of the spring and a second end (13) of the spring, the spring being intended to be connected mechanically to a housing at each of the first and second ends, the spring comprising, between the first and the second end, at least one member (17) intended to act by contact on an element (42) of the clock mechanism, characterized in that the body comprises a deformable zone (14) extending in a curve (18) and in that the curve comprises a first part (18a) that is concave when viewed from the first end.
Claims21
A spring for a horological mechanism, the spring comprising:
- a body extending between a first end of the spring and a second end of the spring, the spring being configured to be connected mechanically to a frame at each of the first and second ends,
- between the first and the second end, at least one lever configured to act by contact on an element of the horological mechanism,
- wherein the body comprises an elastically deformable zone extending in a curve, and wherein the curve comprises a first part that is concave when viewed from the first end;
- and wherein the lever extends along a half-line comprised in a second half-plane that is complementary to a first half-plane in which there extends a part of the deformable zone extending in the concave first part of the curve from one end of the spring, the first and second half planes being separated by a straight line passing through axes of mechanical connections for connecting the spring to the frame.
