Definitions
- the invention relates to a clock resonator comprising at least one oscillating mass with respect to a connecting element which it comprises and which is arranged to be fixed directly or indirectly to a structure of a clockwork movement, said at least one a mass being suspended from said connecting element by crossed blades which are elastic blades which extend at a distance from each other in two parallel planes, and whose projections of directions on one of said parallel planes intersect at level of a virtual pivot axis of said mass, and together define a first angle which is the apex angle, from said virtual pivot axis, to which extends the portion of said connecting member which is located between the fasteners said crossed blades on said connecting element.
- the invention also relates to a watch movement comprising such a resonator.
- the invention also relates to a watch, including such a movement, and / or such a resonator.
- the invention relates to the field of time bases for mechanical clockwork mechanisms, in particular for watches.
- a crossed-leaf rocker is a resonator that can be used as a timebase in a mechanical watch, instead of a balance-spring.
- the document EP 2,911,012 A1 in the name of CSEM describes a virtual rotary clock oscillator with a pendulum which is connected by several flexible blades to a support, in particular in a monolithic embodiment. At least two flexible blades extend in planes perpendicular to the plane of the oscillator, and intersecting each other along a line defining the oscillation geometric axis of the oscillator, this axis intersecting the two blades to seven eighths of their respective length.
- the blades can originate perpendicularly to the sides of a regular inner polygon with N sides, with a symmetry of order N around the virtual oscillation axis, but the only particular configuration illustrated is that of an inner square, in which the two planes comprising the blades are perpendicular to each other.
- the number of blades and their arrangement is defined by a compromise between the congestion granted to the system, particularly from an aesthetic point of view, and the stability of the system.
- the document EP 2,911,012 A1 does not disclose particular geometrical parameters to be favored for the best isochronism.
- Cross slides are also known from the document EP2645189 .
- a crossed-leaf tuning fork is known from the document US3628781 , but not in watchmaking.
- the invention proposes to eliminate these disadvantages by proposing an optimized geometry.
- the invention relates to a clock resonator according to claim 1.
- the invention also relates to a watch movement comprising such a resonator.
- the invention also relates to a watch comprising such a movement, and / or such a resonator.
- center of mass used here can also be understood as the "center of inertia”.
- An explanatory example relates to a clock resonator 100 comprising at least one mass 1 oscillating relative to a connecting element 2 that includes this resonator.
- This connecting element 2 is arranged to be fixed directly or indirectly to a structure of a clockwork movement 200.
- This at least one mass 1 is suspended from the connecting element 2 by crossed blades 3, 4, which are elastic blades which extend at a distance from one another in two parallel planes, and whose projections directions on one of these parallel planes intersect at a virtual pivot axis O of the mass 1, and together define a first angle ⁇ which is the apex angle, from this virtual pivot axis O, face to which extends the portion of the connecting element 2 which is located between the fasteners of the crossed blades 3, 4, on the connecting element 2.
- crossed blades 3, 4 are elastic blades which extend at a distance from one another in two parallel planes, and whose projections directions on one of these parallel planes intersect at a virtual pivot axis O of the mass 1, and together define a first angle ⁇ which is the apex angle, from this virtual pivot axis O, face to which extends the portion of the connecting element 2 which is located between the fasteners of the crossed blades 3, 4, on the connecting element 2.
- this first angle ⁇ is between 68 ° and 76 °.
- the mass 1 is a pendulum, as visible on the Figures 1 and 1A , which illustrate, in solid lines, the geometry of a resonator 100 with cross-leaf balance, in its rest position.
- a rocker 1 is held fixed to a connecting element 2 by two crossed blades 3 and 4.
- These crossed blades 3 and 4 are elastic blades which extend at a distance from one another in two parallel planes, and of which the projections of the directions on one of these parallel planes intersect at a virtual pivot axis O of this balance 1.
- These crossed blades allow the rotation of this balance 1, and substantially prevent the translation of the balance 1 in the three directions XYZ, and provide good resistance to small shocks.
- the figure 1 represents a general case where the embedding of crossed blades 3, 4 is oblique in the connecting element 2 which carries them.
- the Figure 1A represents a preferred configuration where this embedding is carried out at a surface which is orthogonal to the end of each blade 3, 4, at its embedment.
- the origin of the coordinates O is placed at the intersection of the blades 3 and 4 when the resonator 100 is in its rest position.
- the instantaneous center of rotation and the center of mass of the balance are also located at the origin O when the balance is in its rest position.
- the bisector of the first angle ⁇ defines a direction X with which the projections of the two blades 3 and 4 in one of said parallel planes make an angle ⁇ which is half of the first angle ⁇ .
- the resonator 100 is symmetrical with respect to the axis OX.
- the first angle ⁇ has a value of 90 °.
- the inner radius ri is the distance between the point O and the embedding of the blades 3 and 4 in the connecting element 2.
- the outer radius re is the distance between the point O and the embedding of the blades 3 and 4 in the pendulum 1.
- the first angle ⁇ is the angle between the two blades 3 and 4 when the resonator 100 to balance is in its rest position.
- This first angle ⁇ is the apex angle (in O) which defines the opening of the blades 3 and 4 with respect to the connecting element 2, and in front of which extends the portion of this connecting element 2 which is located between the fasteners of the crossed blades 3 and 4 on the latter.
- the Figures 1 and 1A show an instantaneous value ⁇ i of the current angle ⁇ , corresponding to the deviation of a point M towards its instantaneous position Mi, corresponding to bent positions 3i and 4i of the blades 3 and 4, shown in broken lines on the Figures 1 and 1A .
- This optimal geometric configuration may vary very slightly, depending on the width of the blades 3 and 4, and the amplitude of the oscillation of the balance.
- the resonator 100 is monolithic.
- the resonator 100 is made of micro-machinable material that can be produced by "MEMS” or “LISA” technologies, or in silicon or in silicon oxide, or in at least partially amorphous metal, or in metallic glass, or in quartz, or in DLC.
- the first angle ⁇ is between 70 ° and 76 °.
- the first angle ⁇ is between 70 ° and 74 °.
- the invention relates to a clock resonator with crossed blades of the tuning fork type, as visible on the figure 8 .
- the invention also relates to a watch movement 200 comprising at least one such resonator 100.
- the invention also relates to a watch, including such a movement 200, or / and such a resonator 100.
- the invention thus makes it possible to make a cross-beam resonator simultaneously isochronous and independent of the positions.
