Abstract: A pivot mechanism for guiding in rotation comprises a mobile element connected to a fixed element through flexible connections; with the flexible elements being configured to guide the mobile element according to a rotational movement in a plane, around a pivoting axis perpendicular to the plane; with each of the flexible connections comprising an intermediary junction provided with an expansion slot, the expansion slot being configured to expand during the rotation of the mobile element, so that the mobile element can pivot according to a second angular amplitude that is greater than a first angular amplitude achieved without said expansion slot; with the intermediary junctions being connected to one another by a coupling member; each of the coupling members being configured so as to prevent a movement out of the plane and a lateral movement in the plane of the mobile element. The pivot mechanism has a very high rotational amplitude.

Abstract: A sprung balance type mechanical timekeeper, includes a spiral spring (10), a balance (20) and an escapement mechanism (30) connected by a point of attachment (12) to the spiral spring and arranged to sustain an oscillation of the balance. The escapement mechanism (30) is connected to the point of attachment (12) of the spiral spring by a chassis (40) pivoted about the axis (A) of the balance. An outer end (12) of the spiral spring (10) is attached to this transverse pert (40) at a location located on one side of the balance axis (A). The chassis (40) includes two branches extending on either side of the axis of the balance (20) and forming a rotary plate whose axis of rotation is coincident with the axis of oscillation of the balance (20). The escapement mechanism (30) is located on the other side of the balance axis (A) and acts on the pivoted chassis (40) so as to free its rotation and thus make the attached end (12) of the spiral spring rotate.
