Definitions
- the present invention relates to a bistable mechanical device, particularly for the watch industry.
- WO 99/64936 a timepiece exhaust using a bistable mechanical device comprising a leaf spring which works in buckling.
- the leaf spring is fixed at both ends to recesses or pivoting members, and its midpoint is kept aligned with said two ends. The distance separating the two recesses is such that the leaf spring undergoes a compression which forces it to deform according to a second mode buckling.
- the leaf spring thus has two convexities of opposite directions on either side of its midpoint.
- the leaf spring can occupy two stable functional states, the transition from one to the other of these stable functional states being effected by reversing the direction of the two convexities.
- an armature lever acting symmetrically in the region of the two convexities deforms the leaf spring from one of its stable functional states to a metastable state close to an unstable state corresponding to a fourth mode buckling, to arm the leaf spring.
- a trigger rocker located in the midpoint zone acts on the leaf spring to tilt it into its other stable functional state.
- This switch can be broken down into two phases, one requiring a small energy input, the other the restitution of a much larger energy. Taking as reference an anchor escapement, the first phase can be compared to the release, the second to the pulse. The difference lies in the fact that these phases correspond to perfectly stable energy exchanges, which can not be the case with an anchor escapement.
- the arming lever is actuated by integral armature cams of exhaust gears driven by the finishing gear of the timepiece.
- the rocker détente cooperates with a balance-balance oscillator and includes for this purpose a fork of the same type as conventional anchor forks.
- the energy allowing the trigger rocker to move the leaf spring into its other stable functional state since its state of arming is provided by the balance, when a peg secured to the pendulum collides with the input horn of the fork .
- the passage of the leaf spring from one stable state to another changes the inclination of the zone of the midpoint, which causes the trigger rocker to rock, which then imparts a pulse to said peg secured to the balance.
- FIG. 1 shows four different states of the leaf spring according to this document WO 99/64936, namely a state of rest (FIG. 1 (a)) where the leaf spring is not still subjected to compression causing buckling, a first stable functional state (solid line of Figure 1 (b)) where the recesses to which are fixed the ends of the leaf spring have been brought together to flamber the leaf spring, a metastable state close to an unstable state where the leaf spring is armed (solid line of Figure 1 (c)) and a second stable functional state (solid line of Figure 1 (d)).
- a disadvantage of this bistable mechanical device is that it is difficult to adjust the tension of the leaf spring, that is to say the compression applied to its ends, while maintaining fixed the line connecting said ends (passage of the figure 1 (a) in Figure 1 (b)). If the alignment of the ends of the leaf spring is modified during the adjustment, the operation of the exhaust will be disturbed because the asymmetry will generate difficulties in keeping to a minimum the energy required for the disengagement (first phase of the tilting) in one of the two alternations. A release requiring too much energy will cause a drop in performance, increase the risk that the system is not self-starting and may be a cause of anisochronism.
- bistable mechanical device Another type of bistable mechanical device is described in patent application WO 2013/144236.
- This device also used as part of an exhaust, comprises two parallel flexible blades whose median parts are connected by a movable frame and whose ends are fixed to the masses themselves fixed to a fixed structure.
- the flexible blades are prestressed in buckling.
- the distance separating the masses can be adjusted by turning eccentrics which act on the masses.
- the movable frame moves substantially in translation as the flexible blades move from one stable functional state to another.
- the movable frame is on an inner circumference of the spouts which cooperate with the teeth of an escape wheel.
- the movable frame also carries an arm that defines a fork similar to that of a classic Swiss anchor, to cooperate with a peg of a pendulum.
- This device has the same disadvantage as the device according to WO 2009/1 18310, namely the need for a precise adjustment of the compression applied to the flexible blades.
- Patent application EP 2730980 also discloses a bistable mechanical device comprising flexible blades which are prestressed by buckling during their manufacture by growth of silicon oxide on silicon oxide. silicon or by a cooling step playing on the difference of the thermal coefficients of silicon and silicon oxide.

- the bistable mechanical device has a zero energy level in the idle state and a non-zero energy level in each of the first and second stable functional states.
- the bistable mechanical device will have substantially identical respective energy levels in the first and second stable functional states. These energy levels are pre-established, that is to say, determined during the manufacture of the bistable mechanical device. No adjustment of the tension of the resilient blades is necessary in the present invention.
- the resilient blades may be portions of the same leaf spring or be blades separated from each other and coupled, or coupled to each other.
- the state of rest of the bistable mechanical device is a state occupied by the bistable mechanical device before its final assembly in a mechanism intended to use it. However, the present invention does not exclude that this state of rest can also be occupied by the bistable mechanical device after its final assembly in said mechanism.
- the first and second stable functional states are states that can occupy the bistable mechanical device after its final assembly in said mechanism. However, the present invention does not exclude that the first and second stable functional states can also be occupied before mounting the bistable mechanical device in said mechanism.
- the bistable mechanical device further comprises a rigid frame carrying the first and second resilient blades.
- the first and second resilient blades together form or form part of a spring whose two ends are attached to the rigid frame.
- a midpoint of the spring may be located on the line passing through said two ends or, alternatively, out of said straight line.
- each of the first and second resilient blades are fixed to the rigid frame and in the first and second stable functional states a rigid and movable connecting member with respect to the rigid frame connects the respective middle portions of the first and second elastic blades.
- the bistable mechanical device comprises first and second stages, the first stage comprising the first elastic blade, a third preformed elastic blade substantially parallel to the first elastic blade and a first rigid connecting element connecting the parts. medians of the first and third elastic blades, the second stage comprising the second elastic blade, a fourth preformed elastic blade substantially parallel to the second elastic blade and a second rigid connecting element connecting the middle portions of the second and fourth resilient blades, the two ends of each of the first to fourth resilient blades being fixed to the rigid frame, and in the first and second stable functional states the first and second connecting elements are assembled to one another.
