摘要： A horological resonator mechanism, including a structure and an anchoring unit from which is suspended at least one inertial element arranged to oscillate along a first degree of freedom in rotation RZ about a pivoting axis extending along a first direction Z, the inertial element being subjected to return forces exerted by a virtual pivot including a plurality of substantially longitudinal elastic strips, each fastened, at a first end to the anchoring unit, and at a second end to the inertial element. Each elastic strip is deformable essentially in a plane XY perpendicular to the first direction Z. The anchoring unit is suspended from the structure by a flexible suspension arranged to allow the mobility of the anchoring unit along a plurality of degrees of freedom including at least two in the plane XY, along a direction X and along a direction Y orthogonal to the direction X.

摘要： A device (1) for guiding a rotary shaft (6) of a sprung balance. The device includes at least the rotary shaft and a guide bearing (2) for guiding an end of the rotary shaft of the sprung balance, the guide bearing including at least one blade (3) and a surface (5) for coming into contact with and holding the end of the rotary shaft of the sprung balance. At least one end part of the shaft and at least the blade and the contact surface of the guide bearing are made of a material with a Young's modulus of less than or equal to 100 GPa and to reduce the coefficient of friction of the contacting parts.

摘要： A timepiece resonator including an inertia element suspended from a flexible strip deformable in a plane XY parallel to a longitudinal direction Y, and whose transverse extension along a transverse axis X, in projection onto the plane XY, is variable and of positive value on at least one side of the neutral axis (FN) of the strip, which includes, at a distance from its embedments, at least one rib extending substantially along an axis Z perpendicular to the plane XY, each having at least one generatrix which is farther from the neutral axis (FN) than the external surfaces of the sections of the strip located outside the ribs, and the longitudinal extension (LN) of each rib of the strip, along the longitudinal axis Y, is less than one fifth of the length L of the strip between its embedments.

摘要： A flexible guide for a rotary resonator mechanism, in particular of a horological movement, the guide including a first support, an element movable relative to the first support, a first pair of flexible strips connecting the first support to the movable element, so that the movable element can displace relative to the first support by bending the strips in a circular movement about a centre of rotation, the flexible guide being arranged substantially in a plane, including a prestressing device, the prestressing device being configured to apply a force for buckling the flexible strips by bringing the first support closer to the movable element, so that the flexible guide includes two stable positions of the element movable relative to the first support for which the return moment is zero, the two stable positions having a predetermined angle of rotation therebetween.
