Abstract: A method for making a flexure bearing for an oscillator with an inertial element oscillating in a plane supported by flexible strips fixed to a stationary support returning it to a rest position includes: forming the bearing with basic strips in superposed levels, each having an aspect ratio of less than 10; breaking down the number of basic levels into a plurality of sub-units, each including one or two strips joining a basic support and a basic inertial element, which are made by etching substrates; assembling the sub-units by joining their basic inertial elements; and fixing the basic supports to the support, directly or via translational tables along one or two in-plane translational degrees of freedom, of lower translational stiffness than that of the sub-unit.

Abstract: A flexible timepiece component, in particular for an oscillator mechanism or for a barrel of a horological movement, the component extending along a main plane (P) and including at least a part made of a composite material (1), the composite material (1) including a matrix (2) and a multitude of nanowires (3) distributed in the matrix (2), the nanowires (3) being juxtaposed, the matrix (2) including a material (4) for filling the interstices between the nanowires (3) to join them to each other, each nanowire (3) forming a solid one-piece tube, the nanowires (3) being disposed substantially parallel to an axis (A) substantially perpendicular to the main plane (P) of the component (6, 7).

Abstract: A method for manufacturing a flexible strip, including forming a plate of the required thickness with one or more micromachinable substrate wafers; affixing, on either side of the plate, an upper mask with an upper window and a lower mask with a lower window, of identical geometry; etching the plate, at least to mid-thickness, from the upper side of each upper etching window, and from the side of each lower etching window; removing the upper mask and the lower mask, to delimit a flexible strip having a height equal to the thickness of the plate, and whose edges are as-etched. A flexible strip made of micromachinable material, including, between two parallel upper and lower surfaces, two peripheral, tapered and reverse-tapered edge surfaces, for a flexible pivot, a resonator, a movement or a watch.

IPC: G04B17/10
Abstract: A mechanical timepiece oscillator includes, between a support and an inertial element, a flexure bearing with flexible strips crossed in projection, including, superposed, an upper level that includes, between an upper support and an upper inertial element, an upper primary strip in a first direction and an upper secondary strip in a second direction, and a lower level that includes, between a lower support and a lower inertial element, a lower primary strip in the first direction and a lower secondary strip in the second direction. The upper level and lower level include, between the support and the upper or respectively lower support, a translational table with an elastic connection along one or two axes of freedom in the oscillation plane, of lower stiffness than that of each flexible strip.

Abstract: A mechanical timepiece oscillator including, between a first element and a second inertial element, more than two distinct flexible strips returning the inertial element to a rest position in an oscillation plane, wherein the projections of these strips cross each other, at a point, through which passes the axis of pivoting of the second solid inertial element, and the height to thickness aspect ratio is less than 10 for each strip.
