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.

摘要： A horological mobile component, including around an axis, a first element including a first shoulder and a second element including a second shoulder which cooperates by friction with a third shoulder that is included by a third element interposed between the first element and the second element, this third element includes a fourth shoulder cooperating by friction with the first shoulder or being driven onto this first shoulder, and the diameter of the third shoulder is at least double the diameter of the fourth shoulder, and the second element includes a main hollow defining at least two bearing surfaces each including one or two bearing sectors belonging to the second shoulder.
