    Field of the invention
    The invention relates to a clock movement comprising at least one time base comprising a resonator associated with a mechanical escapement mechanism.
    The invention also relates to a timepiece, in particular a watch, comprising at least one such movement.
    The invention relates to the field of time bases in mechanical watchmaking.
    Background of the invention
    [0004] The chronometric properties of timepiece mechanisms have always been altered by friction, and isochronism also greatly depends on the position in space of the timepiece, in particular a watch, with respect to the field of gravity. .
    [0005] Lubrication makes it possible to reduce friction, but creates pollution inside the timepiece, which is added to that created by wear debris, and performance is not constant over time. .
    Summary of the invention
    The invention proposes to equip the time bases with minimal or zero contact guides, guaranteeing the regularity of the chronometric performances, good isochronism, excellent aging, and easy after-sales service.
    [0007] The invention also proposes to reduce the losses due to the contacts in the escapement mechanisms.
    [0008] It is a question, again, of bringing the desired improvements to any type of timepiece, even to parts produced in very small quantities such as marine chronometers or the like.
    [0009] To this end, the invention relates to a clock movement according to claim 1.
    The invention also relates to a timepiece, in particular a watch, comprising at least one such movement.

    Detailed Description of Preferred Embodiments
    The block diagram of Figure 1 shows the essential functions of a timepiece 2000, in particular a mechanical watch, which includes a mechanical time base 300, which includes a resonator 100 and a distribution 200:10: power source;20: energy accumulator;30: counting / transmission; with a first output on display 40,and a second outlet on distribution 200 (exhaust),which distribution 200 provides energy to a resonator 100 which performs the regulation of this escapement.
    [0013] Each of these functions can be performed in different ways. In most current mechanical watches, the energy source is produced by an oscillating weight set in motion by the wearer, or else by the action of the user on a winding stem. The energy accumulator is a barrel. Counting and transmission are carried out by a gear train called a gear train. The display is achieved by hands plumb with a dial, or by discs, or even by a tourbillon cage or carousel, or other. Regulation is performed by a resonator, most commonly of the balance-spring type. The distribution is carried out by an escapement, and is most often carried out by a Swiss lever escapement.
    The escapement mechanism 200 includes at least one escape wheel set 201, generally an escape wheel, which is driven directly or indirectly by the gear train. This escape wheel is periodically stopped or braked, either directly by a mobile inertial mass 1 that the resonator comprises, or indirectly by such an inertial mass 1 through at least one retainer 210; most often, this retainer 210 is an anchor, or even an articulated anchor, or the like.
    The resonator 100 (or oscillator), which moves back and forth at a regular rate, is responsible for the good chronometric precision of the watch. The oscillations of this resonator are maintained and counted by the escapement. The resonator 100 comprises at least one mobile inertial mass 1, generally in rotation. In most mechanical watches, this inertial mass 1 is a balance wheel, which performs a limited stroke oscillation. An oscillation of the balance wheel 1 comprises two alternations (one in each direction of rotation).
    [0016] In lever escapement mechanisms, the impulse is the action of a tooth 202 of the escape wheel 201 on the impulse plane of a pallet 204 of the anchor 210. After this pulse, the rest corresponds to the positioning of the tooth 202 of the escapement wheel 201 resting on one face of the pallet 204, while the pendulum 1 traverses an additional arc. The fork 203 of the anchor 210 is then held against a limiting abutment 205, thanks to a geometric safety called pulling, which opposes a resistance to the disengagement explained below: the tooth 202 of the escape wheel 201 is in contact punctual with the plane of rest of the anchor blade 204, and the pulling angle is defined by the angle between this plane of rest and a perpendicular to a radial coming from the axis of the anchor and passing through this point-of-contact. After the impulse given by the tooth 202 of the escapement wheel 201 to the entry pallet 204 of the anchor 210, the lost path corresponds to the free travel of the anchor 210 until contact between the fork 203 of the anchor and a stop 205. The clearance corresponds to the travel traveled by the anchor 210 to release the escapement wheel 201, and corresponds to the total of the rest and the path lost. The escape wheel 201 recoils during disengagement, under the thrust of the exit pallet 204 of the anchor 210. The fall is the idle stroke of the escape wheel 201 between the end of the impulse of a first tooth 202 on a pallet 204 of the anchor 210, and the fall of a following tooth 202 on the other pallet 204 of the anchor 210.
    [0017] Here, the impulse is qualified as indirect, when a retainer 210, in particular an anchor, is interposed between the escapement wheel 201 and the resonator 100: therefore the escapement is then free.
    [0018] There are many ways to make a mechanical resonator and many ways to make an escapement. In particular, the interaction between the components, and in particular within the escapement, can be mechanical and/or magnetic, or even electrostatic. The escapement-resonator assembly can be fixed relative to the plate of the watch or embedded in a mobile, as in a tourbillon or a carousel.
    [0019] The most common resonator is a balance-spring assembly consisting of a shaft which carries an inertial element 1, sometimes called a rim or balance, and a spiral spring 2, as seen in Figure 2. The The shaft is pivoted in mechanical bearings. The spiral spring 2 is connected to the shaft at its center, via a ferrule, and to the plate 3 at its periphery, via a stud. These mechanical bearings can be pierced ruby stones, ball bearings, bearings or even knife pivots.
    [0020] The development of micro-technologies has allowed the advent of components incorporating elastic blades, or similar elastic return means. A resonator 100 with flexible guidance comprises an inertial element 1, sometimes called rim or pendulum, and a flexible guide comprising at least one flexible blade 4 or 5. The flexible guide is connected on one side to rim 1 and on the other to the plate 3. Such a flexible guide fulfills both a guide function and an elastic return function. A resonator with flexible guidance does not have a shaft with pivots which rub in bearings, and, consequently, has the advantage of not being subjected to variations in friction of the pivots in the different positions of the watch in the field of gravity, especially in vertical positions. An example of resonator 100 with flexible guidance is the resonator with two blades 4 and 5 in parallel planes, and which are crossed in projection on one of these planes, as seen in FIG. 3. Examples of resonators comprising flexible blade guides can be read in document EP3035126B1 in the name of THE SWATCH GROUP RESEARCH & DEVELOPMENT Ltd, and document EP3054356B1 in the name of ETA Manufacture Horlogère Suisse.
    Another example is a pendulum 1 suspended in the middle of a torsion wire (torsion pendulum), fixed to plate 3 at both ends, as described in document EP2893404B1 in the name of BLANCPAIN.
    [0022] Another technology developed to eliminate friction due to guiding relates to magnetic guiding, or even electrostatic guiding, which is more difficult to implement in practice. A magnetic pivot resonator comprises, like the balance-spring, a shaft, a rim 1 and a return spring, but the shaft is held in place by magnetic forces as seen in Figure 4 where the ends of the balance shaft 1 are guided in magnetic pivots 6, or else is held by magnetic and mechanical forces. The advantage is to reduce friction with respect to pivots in mechanical bearings. An example of a balance wheel on magnetic pivots is described in document EP2638436B1 in the name of MONTRES BREGUET.
    A combined guide resonator is obtained by any combination of the systems proposed above.
    [0024] The most classic escapement mechanisms are described in the book "Theory of escapements", by Sylvain AUBRY, published by the Federation of Technical Schools in Switzerland, as well as in the "Illustrated Professional Dictionary of Watchmaking". , by GA BERNER, published by the Swiss Chamber of Watchmaking, La Chaux-de-Fonds, and also available online.
    [0025] The Berner dictionary, well known to watch manufacturers, describes in particular: §1436 1) permanent contact escapements, in which the balance wheel is constantly in contact with a component of the escapement, and among which we find: – recoil escapements, where the escape wheel recoils during part of the oscillation due to eccentric resting surfaces; – resting or rubbing resting escapements, illustrated in figure 9, where the escapement wheel does not move back during oscillation due to concentric resting surfaces; §1436 2) free escapements, in which the balance only has contact with a component of the escapement during release and impulse; §1437 the escape wheel escapement; §1438 the pirouette escapement by Huygens (1657); §1439 the recoil anchor escapement of pendulums, by R. Hooke (1657); §1440 G. Graham's anchor escapement (1720); §1441 G. Graham's cylinder escapement (1720), shown in figure 10; §1442 the Swiss lever escapement (1815), illustrated by figure 5, whose functions are: rest, release, impulse, fall, lost path, recoil, draw; the impulse is shared between the pallets of the anchor and the impulse planes of the wheel §1443 the English lever escapement by T. Mudge (1759); the impulse is made entirely on the pallets of the anchor; §1444 the detent escapement, with a direct tangential impulse the old executions of P. Le Roy, J. Arnold, T. Earnshaw (1792), illustrated by figure 8; a spring called trigger controls the release of the escape wheel with each oscillation of the balance wheel; the impulse occurs near dead center, the equilibrium position of the balance-spring; §1445 the peg escapement, notably in the Roskopf execution, by L. Perron (1867); dowels replace pallets; §1446 the lost stroke escapement; the oscillation includes an alternation without pulse; §1447 the constant-force escapement; to transmit a constant torque to the regulator member, the gear train is replaced or supplemented by an intermediate spring which is periodically armed with always the same quantity of energy; §1448 the recoil escapement; the anchor carries a counterweight capable of abutting against an adjustable stop; §1448 electric exhaust; §1449 Hipp's electric escapement; §1450 Hipp's reed escapement.
    We still know, and not exhaustively, many exhaust geometries, among which we cite the best known from the 18th to the 20th century:the coaxial escapement by G. Daniels (1960), illustrated in figure 6;the escapement of R. Robin (1791), illustrated by figure 7;J. Harrison's Grasshoper escapement (1720), shown in Figure 11;the duplex escapement by P. Le Roy (1750), illustrated in figure 12;C. Fasoldt's two-wheel escapement (1865), shown in Figure 13;the articulated pallet escapement, illustrated by figure 14;the natural escapement of A.L. Breguet (1808), illustrated by figure 15;the special escapement with a direct tangential impulse according to the patent document CH715093 in the name of SEIKO, illustrated by figure 16;the comma escapement by J.A. Lépine (1766);the R. and F. Melly escapement (1825);P.F. Ingold's escapement (1840);A.M. Potter's Escape (1887);the gravity escapement by T. Mudge (1767);the escapement of C. MacDowal (1850);E.B. Denison's three-legged escapement (1851);E.B. Denison's Big Ben escapement (1859);S. Riefler's exhaust (1888).
    [0027] It should be noted that the escapement mechanism, which is referred to here as the special direct tangential impulse escapement mechanism, according to patent application CH715093 in the name of SEIKO, comprises an escapement wheel which rotates around a first axial line using transmission energy, and a control element which rotates and stops the escapement wheel set based on the rotation of a balance-spring, which rotates alternately around a second axial line in a first direction of rotation and a second direction of rotation opposite to each other. The escapement wheel directly transmits the energy transmitted to the balance-spring when the balance-spring rotates in the first direction of rotation, and indirectly transmits the energy transmitted to the balance-spring via the control element when the balance-spring rotates in the second direction of rotation. And the control element controls the rotation of the escapement wheel set in such a way that a first rotational angle of action traversed within the framework of the direct transmission of energy from the escapement wheel set to the balance-spring differs from a second rotational angle of action traversed within the framework of the indirect transmission of energy from the escapement wheel set to the balance-spring.
    [0028] The thesis of Doctorate of Science No. 3806 defended by Mr. Thierry CONUS on 06.01.2007 before the Faculty of Engineering Sciences and Techniques, Laboratory of Robotic Systems 2, of the Federal Polytechnic School of Lausanne (Switzerland ) whose title is: Design and multi-criteria optimization of free escapements for mechanical wristwatches, provides valuable information on the different types of escapement mechanisms.
    The invention proposes to improve the energy efficiency of escapement mechanisms, by modifying known and proven types of escapement as to their horological qualities, by designing improved guides compared to the prior art: flexible guides, magnetic or electrostatic guides, ball bearing guides.
    To this end, the invention relates to a clock movement 1000 comprising at least one resonator 100 arranged to cooperate with at least one escapement mechanism 200, in particular but not limited to a mechanical escapement mechanism.
    The invention also relates to a mechanical watch 2000 comprising at least one such clock movement 1000.
    The resonator 100 comprises at least one inertial mass, which is arranged to cooperate with at least one escapement mobile, either directly or through a retainer.
    [0033] According to the invention, this at least one inertial mass and/or this escape mobile, and/or the retainer when the escape mechanism 200 comprises one, is guided or guided by at least one guide which is flexible guidance, or magnetic or electrostatic guidance, or ball bearing guidance.

More particularly, at least one inertial mass 1 of the resonator is arranged to oscillate around a virtual axis defined by a flexible guide 4 or 5 which carries it.
    [0035] In a second family of embodiments, this at least one inertial mass and/or this escape mobile, and/or the retainer when the escape mechanism 200 includes them, is guided or guided by at least one guide magnetic or electrostatic. More particularly, at least one inertial mass 1 of the resonator is arranged to oscillate around a virtual axis defined by a magnetic 6 or electrostatic guide which carries it.

More particularly, at least one inertial mass 1 of the resonator is arranged to oscillate around a virtual axis defined by a ball bearing which carries it.
    [0037] More particularly, in one or the other of these three families of embodiment, the interaction between at least two components of the escapement takes place by magnetic forces. An example of a magnetic escapement is described in document EP3128379B1 in the name of THE SWATCH GROUP RESEARCH & DEVELOPMENT Ltd.
    More particularly, in one or the other of these three families of embodiment, the interaction between at least one component of the escapement and at least one inertial mass takes place via magnetic forces.
    More particularly, in one or the other of these three families of embodiment, the interaction between at least two components of the escapement takes place by magnetic forces and by mechanical contacts. An example is described in document EP3128380B1 in the name of ETA Manufacture Horlogère Suisse.
    [0040] More particularly, in one or the other of these three families of embodiment, the interaction between at least one component of the escapement and at least one inertial mass takes place by magnetic forces and by mechanical contacts. .
    [0041] All the combinations described above can be mounted in a tourbillon.
    [0042] All the combinations described above can be mounted in a carousel.
    [0043] More particularly, the escapement is indirect, and the escapement mechanism 200 comprises at least one escapement wheel 201 and at least one stopper 210, and a said escapement wheel and/or a said stopper is arranged to pivot, or respectively arranged to oscillate, around a virtual axis defined by a magnetic or electrostatic guide which carries it or respectively which carries it.
    [0044] More particularly, the escapement mechanism 200 includes at least one escape wheel, and the movement includes a constant force mechanism for driving the escape wheel, in any of the combinations described above. -above. More particularly, this constant force mechanism is a fusee mechanism, or a deadbeat seconds mechanism with balance spring/escape wheel, or a remontoire, or the like.
    Thus the invention relates to a clock movement 1000 comprising at least one time base 300 comprising a resonator 100 associated with a mechanical escapement mechanism 200, said resonator 100 comprising at least one inertial mass arranged to cooperate with at least one escapement mobile, either directly or through a retainer.
    First embodiment: escapement mechanism with at least one direct tangential impulse.
    A first embodiment relates to a resonator 100 which is a flexible guide resonator, of which at least this at least one inertial mass is arranged to oscillate around a virtual axis defined by a flexible guide which carries it, and this escapement mechanism 200 is an escapement mechanism with at least one direct tangential impulse.
    In a first alternative of this first embodiment, this escapement mechanism 200 is an escapement mechanism with a single direct tangential pulse.
    In a second alternative of this first embodiment, this escapement mechanism 200 is an escapement mechanism with two direct tangential impulses.

    More particularly, in one or the other of these alternatives and combinations of this first embodiment, the interaction between at least two elements forming a pair, among this at least one inertial mass, this at least an escapement wheel set, and/or this stopper when the escapement mechanism 200 includes one, is a magnetic interaction, these at least two elements each comprising at least one permanent magnet which is arranged to cooperate and attract or repel a other permanent magnet that comprises the other element of this pair.
    More particularly still, the magnetic interaction within such a pair is a contactless interaction.
    [0061] In a variant of this embodiment comprising a magnetic interaction, the magnetic interaction within such a pair is supplemented by a mechanical interaction, which is arranged to operate in extreme end-of-travel positions.

    In a third alternative of this second embodiment, this escapement mechanism 200 is an escapement mechanism with a direct tangential impulse and an indirect tangential impulse.
    In a fourth alternative of this second embodiment, this escapement mechanism 200 is an escapement mechanism with an indirect tangential impulse and an indirect rubbing impulse.
    In a fifth alternative of this second embodiment, this escapement mechanism 200 is a free escapement mechanism.
    It is understood that, in certain cases only, the fifth alternative can be combined with one of the first four alternatives.
    Thus, in a particular combination of the third and the fifth alternatives, the watch movement 1000 is a free escapement mechanism with a direct tangential impulse and an indirect tangential impulse, and, even more particularly, this mechanism escapement 200 is a Breguet natural escapement mechanism comprising two escape wheels.
    Thus, in a particular combination of the first and the fifth alternatives, the watch movement 1000 is a free escapement mechanism with a single indirect tangential impulse, and, even more particularly, this escapement mechanism 200 is a Fasoldt escapement mechanism.
    Thus, in a particular combination of the second and the fifth alternatives, the watch movement 1000 is a free escapement mechanism with two indirect tangential impulses, and, even more particularly, this mechanism of The escapement 200 is an articulated lever escapement mechanism.
    More particularly, in one or the other of these alternatives and combinations of this second embodiment, the interaction between at least two elements forming a pair, among this at least one inertial mass, this at least an escapement wheel set, and/or this stopper when the escapement mechanism 200 includes one, is a magnetic interaction, these at least two elements each comprising at least one permanent magnet which is arranged to cooperate and attract or repel a other permanent magnet that comprises the other element of this pair.
    More particularly still, the magnetic interaction within such a pair is a contactless interaction.

More particularly, this constant-force mechanism is a fusee mechanism, or a remontoire, or a deadbeat seconds mechanism with balance spring on the escapement wheel set.
    Third embodiment: escapement mechanism with at least one direct rubbing impulse.
    A third embodiment relates to a resonator 100 which is a flexible guide resonator, of which at least this at least one inertial mass is arranged to oscillate around a virtual axis defined by a flexible guide which carries it, and this escapement mechanism 200 is an escapement mechanism with at least one direct rubbing impulse.
    In a first alternative of this third embodiment, this escapement mechanism 200 is an escapement mechanism with a single direct rubbing impulse.
    In a second alternative of this third embodiment, this escapement mechanism 200 is an escapement mechanism with two direct rubbing impulses.

    Thus, in another particular combination of the second and the fourth alternatives, the watch movement 1000 is an escapement mechanism with rubbing rest and with two direct rubbing impulses, and, even more particularly, this mechanism of The 200 escapement is a Graham escapement mechanism.
    Thus, in a particular combination of the first and the fourth alternatives, the watch movement 1000 is an escapement mechanism with rubbing rest and with a direct rubbing impulse, and, more particularly still, this mechanism of escapement 200 is a duplex escapement mechanism.
    Thus, in a particular combination of the second and third alternatives, the watch movement 1000 is a free escapement mechanism with two direct rubbing impulses, and, even more particularly, this escapement mechanism 200 is an articulated lever escapement mechanism.

    In a particular variant of this third embodiment, the movement 1000 includes energy storage means arranged to transmit a motor torque to said at least one escapement mobile through a constant-force mechanism. More particularly, this constant-force mechanism is a fusee mechanism, or a remontoire, or a deadbeat seconds mechanism with balance spring on the escapement wheel set.
    Fourth embodiment: escapement mechanism with at least one indirect rubbing impulse.
    A fourth embodiment relates to a resonator 100 which is a flexible guide resonator, of which at least this at least one inertial mass is arranged to oscillate around a virtual axis defined by a flexible guide which carries it, and this escapement mechanism 200 is an escapement mechanism with at least one indirect rubbing impulse.
    In a first alternative of this fourth embodiment, this escapement mechanism 200 is an escapement mechanism with a single indirect rubbing impulse.
    In a second alternative of this fourth embodiment, this escapement mechanism 200 is an escapement mechanism with two indirect rubbing impulses.
    In a third alternative of this fourth embodiment, this escapement mechanism 200 is an escapement mechanism with a direct tangential impulse and an indirect rubbing impulse.
    In a fourth alternative of this fourth embodiment, this escapement mechanism 200 is a free escapement mechanism.
    In a fifth alternative of this fourth embodiment, this escapement mechanism 200 is a rubbing rest escapement mechanism.
    [0103] It is understood that, in certain cases only, the fourth or the fifth alternative can be combined with one of the first three alternatives.
    Thus, in a particular combination of the second and fourth alternatives, the watch movement 1000 is a free escapement mechanism with two indirect rubbing impulses, and, even more particularly, this escapement mechanism 200 is a Swiss lever escapement mechanism.
    More particularly, in one or the other of these alternatives and combinations of this fourth embodiment, the interaction between at least two elements forming a pair, among this at least one inertial mass, this at least an escapement wheel set, and/or this stopper when the escapement mechanism 200 includes one, is a magnetic interaction, these at least two elements each comprising at least one permanent magnet which is arranged to cooperate and attract or repel a other permanent magnet that comprises the other element of this pair.
    [0106] Even more particularly, the magnetic interaction within such a pair is a contactless interaction.
    [0107] In a variant of this embodiment comprising a magnetic interaction, the magnetic interaction within such a pair is supplemented by a mechanical interaction, which is arranged to operate in extreme end-of-travel positions.
    In a particular variant of this fourth embodiment, the resonator 100 is carried by a tourbillon or by a carousel.
    In a particular variant of this fourth embodiment, the at least one escapement mobile, and/or the retainer when the escapement mechanism 200 includes one, is guided by at least one magnetic or electrostatic pivot. .
    In a particular variant of this fourth embodiment, movement 1000 comprises energy storage means arranged to transmit motor torque to said at least one escapement wheel through a constant-force mechanism. More particularly, this constant-force mechanism is a fusee mechanism, or a remontoire, or a deadbeat seconds mechanism with balance spring on the escapement wheel set.
    The invention also relates to a timepiece, in particular a watch, comprising at least one such movement 1000.
