    Description: [0001] The present invention relates to an anchor escapement mechanism for a timepiece.
    In a traditional Swiss anchor escapement, the horns of the fork which cooperate with the pendulum plate pin for the release of the anchor limit the maximum amplitude that can reach the balance. According to the constructions, this maximum amplitude is of the order of 330 °. If the amplitude of the balance is greater than this value, it will result in a shock between the plateau pin and the reverse of the horns of the fork of the anchor. This phenomenon is called rebate or rebatting and greatly disrupts chronometry. It usually appears when the barrel spring is fully armed and the energy transmitted to the balance via the work train and the exhaust is greater than expected.
    An immediate solution to avoid this phenomenon of rebate is to limit the winding of the mainspring to a given limit torque value. This can be done by sizing the barrel according to the characteristics of the balance and the work train or by stop-type mechanisms (Maltese cross) or other gears limiting the number of winding turns of the mainspring. These two alternatives have the disadvantage of reducing the power reserve of the movement of the timepiece. Another technical solution is still to avoid overvoltages during the winding of the mainspring which could cause a rebate with ratchets of large barrel ratchet. This last solution solves the problem only in the case of overvoltages.
    Exhaust mechanisms specifically arranged to allow large amplitudes of the balance have also been proposed in the prior art. FR 913 031 discloses a cylinder exhaust mechanism in which the balance can follow an amplitude of the order of 630 °. Similarly, FR 1 013 930 describes an anchor escapement mechanism allowing a pendulum amplitude of 1400 °. In the latter case, the escape wheel has a geometry quite unique to the mechanism and could not be replaced by a traditional escape wheel without modifying the operation of the proposed mechanism that would then approach a rubbing rest exhaust .
    [0005] EP 191 460 discloses another type of escapement, in which the anchor is in two parts, each working in different planes and with a dedicated toothing of an escapement mobile, thus comprising two levels of toothings. The two parts of the anchor are rigidly assembled and the amplitude of the balance is in line with that of a Swiss lever escapement of the prior art.
    The object of the present invention is to provide an anchor escapement mechanism allowing a high amplitude of operation of the pendulum while allowing to retain the features and safety of a traditional anchor escapement mechanism and its wheel Exhaust exhaust.
    The present invention relates to an escape mechanism comprising an escape mobile, an anchor mobile comprising a first anchor and a second anchor articulated to one another and a balance wheel, characterized by the fact that the first and second anchors of the anchor wheel each comprise at least one locking member intended to cooperate with the escape wheel and at least one control member intended to cooperate with the balance wheel.
    The present invention also relates to a watch movement comprising such an exhaust mechanism.

    In the embodiment illustrated in the figures, the anchor escapement mechanism according to the invention comprises a conventional exhaust mobile comprising an exhaust pinion 1 and an escape wheel 2.
    The escape mechanism according to the invention further comprises an anchor mobile composed of an inlet anchor 3 and an outlet anchor 4. In the illustrated embodiment (see Fig. 3 and 4), the entry anchor 3 is secured to the cylindrical portion 311 of a first anchor rod 31. Said first anchor rod 31 is guided in rotation between a bridge and the turntable of the watch movement comprising the escape mechanism (not shown) by two pivots 312. The rod 32 of the inlet anchor 3 preferably comprises a stud 33 and, at its end, three input horns 34, 35, 36. L input anchor 3 still supports an entry pallet 5 intended to cooperate with the escape wheel 2 as well as preferably three entry darts 61, 62, 63 at the end of its rod 32.
    As illustrated in particular in FIGS. 5 and 6, in the present embodiment, the output anchor 4 is secured to the cylindrical portion 411 of a second anchor rod 41. Said second anchor rod 41 is guided in rotation between a bridge and the turntable of the watch movement comprising the escapement mechanism (not shown) by two pivots 412. The rod 42 of the output anchor 4 preferably comprises an opening 43 intended to cooperate with the stud 33 of the anchor. entry 3.
    As will be better understood later, the stud 33 and the opening 43 form temporary connection means between the first 3 and the second 4 anchors. Thus, at certain stages of the operation of the escapement, the two anchors are moved together, thanks to a temporary link provided by the temporary link means. At other stages of the operation of the escapement, the two anchors are kinematically independent, the temporary connection means leaving the two anchors free, one with reference to the other. Those skilled in the art could consider other practical solutions to achieve the temporary connection means, with a possibly articulated finger and a pin, or other more complex systems, such as a temporary magnetic link.
    The rod 42 of the output anchor 4 further comprises at its end three output horns 44, 45, 46. The output anchor 4 further supports an output pallet 7 intended to cooperate with the wheel of exhaust 2 and, preferably, three output darts 81, 82, 83 at the end of its rod 42.
    In the illustrated embodiment, the input anchor 3 and the output anchor 4 are rotated coaxially in different planes. An anchor bridge 15 (FIG 1) participates in the rotational guidance of the two anchors 3,4 forming the anchor mobile.
    The exhaust mechanism according to the invention further comprises a regulating member consisting of a balance-spiral assembly. In the embodiment illustrated, the regulating member comprises a balance and its balance spring (not shown), a balance shaft 9 and three plates 10, 11, 12 fitted on said balance shaft 9. The balance shaft 9 is illustrated in particular in FIG. 7. The first plate 10 has a first notch 101 intended to cooperate with the output darts 81 and 82 of the output anchor 4. The second plate 11, in the illustrated embodiment, identical to the first plate 10, comprises also a second notch 111 intended to cooperate with the entry darts 61 and 62 of the input anchor 3. The third plate 12 carries meanwhile a plateau pin 13 whose lower portion 131 is intended to cooperate with the input horns 34, 35, 36 of the input anchor 3 while its upper part 132 is intended to cooperate with the output horns 44, 45, 46 of the output anchor 4. In the form of illustrated embodiment, the third plate 12 is fitted on the balance shaft 9 between the first and second plates 10, 11.
    In the illustrated embodiment, the balance wheel 9, 10, 11, 12 forming the regulating member has a high amplitude, preferably greater than 360 °.
    The operation of the exhaust mechanism according to the present embodiment will now be described in detail with reference to FIGS. 1, 2 and 8 to 10. In the following, the orientations and in particular the directions of rotation are given with reference to the figures.
    The exhaust mechanism is considered in the following initial position which corresponds to a first locking position of the escape wheel 2. In this initial position, the escape wheel 2 is locked, at equilibrium in pressing on the input pallet 5 of the input anchor 3. The input anchor 3 is supported on a first limiting pin not shown in the figures, which prevents it from pivoting in the counterclockwise direction. The output anchor 4 and the entry anchor 3 are in a first position of stable equilibrium with respect to each other in which the exit anchor 4 is supported by its opening 43 on the stud 33 of the input anchor 3 and is thus locked in rotation in the clockwise direction.
    The balance wheel traverses its additional oscillation arc descending in the counterclockwise direction (first alternation) until the upper portion 132 of the pin 13 comes into contact with the output horn 44 of the output anchor 4 (see Fig. 1).
    A first phase of release / pulse then begins (Figure 1 illustrates the beginning of the release). The rocker continues its stroke counterclockwise and the pin 13 drives the output anchor 4 which rotates clockwise. The exit anchor 4 and its opening 43 drive the entry anchor 3 via its stud 33. With the rotation of the entry anchor 3, the entry pallet 5 releases the wheel escapement 2 which is disengaged and transmits the impulse to the balance via the inlet horn 34 which comes into contact with the lower portion 131 of the pin 13 (see Fig. 2).
    At the end of the pulse, the escape wheel 2 is again in equilibrium, bearing this time on the output pallet 7 of the output anchor 4. Said output anchor 4 is itself resting against a second limiting pin (not shown) preventing it from continuing to rotate clockwise. This second locking position of the escape wheel 2 (the first being the initial position) is illustrated in FIG. 8. In this position of the escape mechanism, the inlet and outlet anchors 4 and 4 are always in their first stable equilibrium position (exit anchor 4 supported by its opening 43 on the stud 33 of the anchor input 3).
    In this second locking position, the balance will describe its additional arc ascending in the counterclockwise direction to reach its maximum amplitude which is greater than 360 ° in the illustrated embodiment. In doing so, a little before having made a complete turn (360 °), the pin 13 and in particular its lower portion 131 meets again the input horn 34 of the input anchor 3. The pin 13 causes then the input anchor 3 in the clockwise direction, then leaves it and reaches the maximum amplitude of the balance. In the first stable equilibrium position of the input anchor 3 with respect to the output anchor 4, the input anchor 3 is free to rotate clockwise until reaching a second position of stable equilibrium without driving the output anchor 4, and therefore without releasing the escape wheel 2, thanks to the arrangement of the opening 43 of the output anchor 4. This position of the exhaust mechanism and in particular input and output 3 anchors 4 when the balance reaches its maximum amplitude in its first alternation is illustrated in FIG. 9.
    In this configuration, the dart 62 working with the input horn 34, limits the movements of the input anchor 3, by its interactions with the plate 11. Similarly, the different darts that the exhaust includes, cooperate with the plate 10, respectively 11, to limit the movements of the inlet anchor 3 and outlet 4, when they are not subjected to a pulling force.
    Advantageously, an indexing system can be provided to accurately stabilize the respective angular positions between the input anchor 3 and the output anchor 4. For example, a positioning spring not shown can be fixed to one of the anchors, being arranged to cooperate with a series of notches distributed angularly on the other anchor, on a concentric portion to its pivot axis. The notches are spaced with respect to the next, according to the pitch separating said respective angular positions. Other indexing solutions are possible.
    After reaching its maximum amplitude, the balance initiates a new alternation and travels the additional arc descending clockwise this time. In doing so, the pin 13, and in particular its lower portion 131, comes into contact with the input horn 35 of the input anchor 3 and rotates the latter in the counterclockwise direction before releasing it. The entry anchor 3 then returns to its first position of stable equilibrium with respect to the exit anchor 4 (FIG 8) in which the stud 33 bears against the bottom of the opening 43 of the anchor of 4. The exhaust mechanism and its components have thus found the second locking position illustrated in FIG. 8.
    The pendulum continues its movement and will describe its additional bow down in a clockwise direction. In doing so, a little before having made a full turn (360 °), the pin 13 and its lower portion 131 meet again the input horn 34 and drive the input anchor 3 counterclockwise. The input anchor 3 in its first stable position relative to the output anchor 4 in turn drives the output anchor 4 via the stud 33 and the opening 43 and a second release phase / impulse then begins. By pivoting, the output anchor 4 and its output pallet 7 release the escape wheel 2 which in turn transmits the pulse to the output pallet 7. This pulse is then transmitted to the balance by the output horn 44 the output anchor 4 which cooperates with the upper portion 132 of the pin 13 of the third plate 12.
    At the end of the impulse, the escape wheel 2 is again in equilibrium bearing on the input pallet 5 of the input anchor 3. Said anchor input 3 is back in support against the first limiting pin (not shown) preventing it from continuing to rotate counterclockwise. The exhaust mechanism has thus found its initial position or first locking position of the escape wheel 2. In this locking position, the inlet and outlet anchors 3 and 4 are always in their first stable position one relative to the other (stud 33 resting in opening 43).
    The balance finally travels its additional arc ascending clockwise to reach its maximum amplitude, which is greater than 360 ° in the illustrated embodiment. In doing so, the pin 13, and in particular its upper part 132, comes into contact with the output horn 44 of the output anchor 4 and pivots it anticlockwise before releasing it and continuing its course for reach the maximum amplitude of the pendulum. In their first position of stable equilibrium, the output anchor 4 is free to pivot in the counterclockwise direction without driving the input anchor 3, and thus without releasing the escape wheel 2, thanks to the arrangement of the opening 43 of the output anchor 4. The output anchor 4 pivots counterclockwise until reaching a new stable equilibrium position with respect to the input anchor 3, position guaranteed by a spring positioning not shown. This position of the escape mechanism and in particular of the inlet and outlet anchors 3 and 4 when the balance reaches its maximum amplitude in its second alternation is illustrated in FIG. 10.
    After reaching its maximum amplitude, the pendulum begins a new alternation and runs through its additional arc downward in the counterclockwise direction. In doing so, the pin 13 and in particular its upper portion 132 comes into contact with the output horn 45 of the output anchor 4 and rotates the latter in the clockwise direction before releasing it. The output anchor 4 then returns to its first position of stable equilibrium with respect to the input anchor 3 in which the opening 43 of the output anchor 4 bears against the stud 33. The mechanism exhaust and its components have regained their original blocking position.
    Continuing its rotation, the balance then leads to a new phase of release / pulse and the cycle is resumed.
    In the embodiment above, the anchors of entry and exit forming the mobile anchor are rotated coaxially and in parallel but distinct planes. Other variants are of course possible.
    As described above, the input anchor and the output anchor are articulated by means of the stud 33 of the input anchor cooperating with the opening 43 of the anchor output. Any other type of suitable articulation is conceivable.
    The input and output pallets carried by the inlet anchor respectively the output anchor are each a locking member for cooperating with the exhaust mobile of the exhaust mechanism according to the invention. Any suitable blocking device could be used. Similarly, the input and output horns carried by the input anchor, respectively the output anchor are each a control member intended to cooperate with the balance wheel of the exhaust mechanism according to the invention. Each of the input and output anchors comprises at least one such control member which can take any suitable form. Finally, in the illustrated embodiment, the entry and exit anchors preferably further comprise each three darts which each form a guide member intended to cooperate with the balance wheel.
    The escape wheel could comprise a double escape wheel composed of a first wheel intended to cooperate with the input anchor and its first input pallet and a second wheel intended to cooperate with the anchor output and its output pallet.
    The exhaust mechanism described above allows the entry and exit anchors to occupy a first equilibrium position and, on either side of this first equilibrium position, another position of 'balanced. The pulse being transmitted as the anchors move from the first equilibrium position to one of the other adjacent equilibrium positions.
    The exhaust mechanism can be generalized to more equilibrium positions. The balance wheel can thus be arranged in such a way that it cooperates, at each alternation, n times (n odd and n> 1) with the control member of the first or second anchors. In other words, between the two anchors, we have n ranges. The anchors are thus capable of occupying ((n-1) / 2 + 1) respective angular positions of equilibrium, said anchors being furthermore capable of passing from one respective angular position to another at each cooperation between the mobile balance and the control member.
    More particularly, after the balance wheel has brought the input anchor 3 in a second equilibrium position (as described above, for example page 6, line 16, for the alternation in the direction anti-clockwise), it can continue its rotation in the same direction and shift the input anchor in at least one other stable angular position, without interaction with the output anchor, which remains in blocking function of the escape wheel. The different angular positions are substantially multiples of one step, a pitch corresponding to the angle of the forks. Symmetrically, we have the same displacements during the next alternation.
    The exhaust mechanism according to the invention thus has a counting member cooperations between the balance wheel and said control members during each alternation. This count provided by the counting member is determined by the changes of respective angular positions of the first and second anchors.
    Thus, the balance wheel is arranged to cooperate, during a first alternation, (n-1) / 2 times with the control member of a first of said anchors, and (n-1) / 2 ) +1 times with the control member of the second of said anchors. This makes n cooperations for alternation. During the next alternation, the balance wheel cooperates (n-1) / 2 + 1 times with the control member of the first of said anchors, and (n-1) / 2) times with the control member of the second of said anchors.
    It is thus observed that said respective angular positions are distributed between: - a first central equilibrium position, - (n-1) / 2 other equilibrium positions, respectively resulting from successive displacements in (n-1) / 2 positions of the first anchor relative to the second, first side of the first central equilibrium position, in a first direction and then in a second direction, respectively at the end of an alternation and at the beginning of the consecutive alternation and displacement in (n-1) / 2 positions of the second anchor relative to the first, on the other side of the first central equilibrium position, in the second direction, then in the first direction, respectively at the end of an alternation and at the beginning of the consecutive alternation. Apart from the central equilibrium position, each other position of respective angular equilibrium is thus performed twice, symmetrically with respect to the central equilibrium position. - In particular for issues of size and risk of collision with the escape wheel, is limited and is typically less than 10, preferably less than 6, preferably less than 4.

    In general, the exhaust mechanism according to the invention comprises an escapement mobile, an anchor mobile and a balance wheel. The anchor mobile comprises a first anchor and a second anchor articulated to one another. Each of the first and second anchors carry at least one locking member intended to cooperate with the escape wheel and at least one control member intended to cooperate with the balance wheel. The anchor mobile thus articulated thus has two elements each arranged to cooperate with both the mobile escape (blocking) and with the balance wheel (pulse). Depending on the arrangement of the joint, it is therefore possible to limit or suppress the rebate phenomenon and thus to use a high amplitude balance wheel. In particular, the first and second anchors are preferably articulated to one another to take at least two stable equilibrium positions relative to each other during an oscillation of the balance wheel. In a first equilibrium position, the second anchor drives the first anchor when said second anchor pivots in a first direction, while the first anchor is free to pivot in said first direction until reaching a second equilibrium position without driving. the second anchor. Still in the first equilibrium position, the first anchor drives the second anchor when the first anchor pivots in a second direction, while the second anchor is free to pivot in said second direction until reaching the second equilibrium position without lead the first anchor. In the second equilibrium position of the first anchor relative to the second anchor, said anchors are free to rotate relative to each other, regardless of their direction of rotation. More preferably, in the second equilibrium position, the first anchor is free to pivot in the second direction without causing the second anchor to reach the first equilibrium position and the second anchor is free to pivot in the first direction without leading the first anchor until reaching the first equilibrium position. Thus, it is possible in particular to obtain that, in their first equilibrium position relative to each other and when the input pallet (respectively the output pallet) blocks the escape mobile, the second anchor (respectively the first anchor) can join its second position under the action of the balance wheel without releasing the mobile escape. The balance wheel can thus perform for each of its alternations an arc greater than or equal to 360 °. According to the invention, the mobile escapement (consisting of an escape wheel and an exhaust pinion) and the rocker arm of the exhaust mechanism according to the invention may be all over. made standard. In particular, the balance wheel may have an amplitude less than 360 °. Thus, a free anchor escapement mechanism allowing the use of a balance wheel with high operating amplitude, greater than 360 °, and retaining all the features and advantages of a traditional anchor escapement and, in particular, compatible with a conventional escape wheel. Since the anchor can be partially "retractable", there is more rebat when the plateau pin contacts a horn of the anchor mobile when the amplitude of the pendulum is greater than 330 °. Disturbances in chronometry are therefore greatly limited. In addition, the suppression of the rebate phenomenon makes it possible to simplify the dimensioning of the mainspring associated with the escapement mechanism which does not necessarily depend on the characteristics of the balance. Thus, it is no longer necessary to set an upper limit to the torque generated by the barrel. It is thus possible to increase the tolerances on the value of the torque of the barrel during its implementation in particular. This also makes it possible to consider high spring pairs of barrels for the training of complications or to consider barrels common to several movements / mechanisms with different characteristics. claims
