摘要： A timepiece mechanism includes a first energy source with a regulating member, a second independent energy source, a control member driven by the second energy source, and a blocking device controlled by the first energy source to block the second energy source and release it to allow the control member to be displaced by jumps powered by the second energy source. The blocking device includes first and second mobile parts kinematically interconnected, the first mobile part including a drive device, the second mobile part including a stopping device; a rotating drive member connected to the first energy source and cooperating with the drive device to displace the mobile parts, alternately in opposite directions; and a rotating blocking member connected to the second energy source and cooperating with the stopping device to be blocked by the second mobile part and released at the determined times by second mobile part movement.

摘要： An antishock device intended to protect from shocks a timepiece mechanical oscillator with flexure guiding, the antishock device including a visco-elastic element and a rigid stop, each being configured in such a manner as to cooperate with a portion of the oscillator. The visco-elastic element is configured to be deformed elastically if the oscillator is subjected, in the event of a shock, to an acceleration between 20 G and 1000 G NIHS, preferably between 50 G and 500 G NIHS. The portion cooperating with the rigid stop if the portion is subjected to an acceleration beyond at least 1000 G NIHS, preferably at least 500 G. A timepiece mechanical oscillator includes a balance, a suspension with flexure guiding and elastically restoring the balance into a plane of oscillation and provided with shock protection, the oscillator including at least one antishock device according to the invention.

摘要： 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.

摘要： A mechanism for a timepiece, comprising a an oscillating regulator mechanism, a rotary energy distribution toothed wheel, a blocking mechanism controlled by the regulator mechanism to alternatively hold and release the energy distribution wheel, and a monostable elastic member linked to the regulator mechanism and bearing on the teeth of the energy distribution wheel. The teeth of the energy distribution wheel are adapted to elastically deform the monostable elastic member by cam effect during rotation of the wheel, and the monostable elastic member is adapted to elastically return to its rest position, thus releasing mechanical energy to the regulator mechanism.

摘要： A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.

摘要： A timepiece oscillator structure includes at least one divisible unit, which includes at least one component which includes at least one flexible blade or at least one blade with necks, joining two main units, each more rigid than the flexible blade or blade with necks, where the divisible unit includes at least one gripping unit adjacent to at least one main unit to which it is connected by at least one divisible linkage which is designed in order to make possible the detachment of this gripping unit from the component when the component is fixed, with at least the particular main unit which is adjacent to the gripping unit, to a more rigid external element than the flexible blade or than the necks of the blade with necks.

摘要： Mechanical oscillator including an inertial body joined to a support by an elastic system, the elastic system being arranged to confer the inertial body substantially two degrees of freedom in rotation about a point having a substantially fixed relationship with respect to the support, and substantially no degrees of freedom in translation. The elastic system includes at least two rods and an L-shaped beam the rods and the L-shaped beam being situated in a single plane when the inertial body is in a neutral position.
