    摘要: The mechanical timepiece regulator of the invention comprises a flexure bearing oscillator and a double detent escapement, the oscillator comprising a balance wheel (1) connected to an elastic suspension (2a, 2b) arranged to guide and apply a restoring force to the balance wheel (1) in a plane of oscillation. The escapement comprises an escape wheel (3) and an anchor (4) integrated into the balance wheel (1) and having two arms (5, 6) arranged to receive alternately the impulses of the escape wheel (3). The escapement furthermore comprises two detents (7, 8) alternately locking the escape wheel (3) between two impulses and interacting with the arms (5, 6) of the anchor to release the escape wheel (3) before each impulse, without direct interaction between the anchor and the escape wheel.

    摘要: A timepiece regulator includes a detached lever escapement mechanism, and a resonator with a quality factor Q including an inertia element comprising an impulse pin integral with an inertia element and cooperating with a fork of the lever. This inertia element is subjected to the action of elastic return means directly or indirectly fixed to the plate and is arranged to cooperate indirectly with an escape wheel set comprised in the escapement mechanism. This resonator mechanism is a resonator with a virtual pivot rotating about a main axis (DP), with a flexure bearing subjected to the return force of at least two flexible strips attached to the plate, defining together a virtual pivot with a main axis (DP), the lever pivoting about a secondary axis (DS).

    摘要: The oscillator for a regulator of a timepiece mechanism comprises a frame, a rigid body and a mechanism) for connecting the rigid body to the frame enabling oscillations of the rigid body relative to the frame. The connecting mechanism comprises at least one first and one second rigid parts, and a first and a second flexible elements, in the form of angular sectors of rings. The first and second flexible elements extend mainly in separate non-parallel planes. The first and second flexible elements are concentric. The first and second flexible elements each connect the first and second rigid parts together.
