Definitions

  • the present invention relates to the field of watchmaking. It concerns, more particularly, a free exhaust mechanism combining a direct exhaust and indirect exhaust route.
  • the invention also relates to a timepiece comprising such an escapement mechanism.
  • Lever escapements certainly constitute the most common category of escapements in mechanical watch mechanisms, at least in the class of so-called free escapements.
  • an anchor escapement Associated with a regulating member, typically of the pendulum or balance-spring assembly type, an anchor escapement makes it possible to maintain the oscillations of said regulating member by transmitting to it through regular pulses, at a determined frequency, a fraction of the mechanical energy of the mechanical energy source of a said watch mechanism, usually comprising at least one barrel spring.
  • the escapement also makes it possible to count the oscillations of the regulating organ and, therefore, to count the time.
  • lever escapements have been proposed in the state of the art and are well known to those skilled in the art in the field of watchmaking. Their limitations, equally well known, are mainly a propensity to disrupt the isochronism of the oscillations of the regulating organ due to successive shocks and friction between the anchor and the regulating organ on the one hand as well as the anchor and the exhaust mobile on the other hand, as well as low mechanical efficiency, mainly for the same reasons. Indeed, it is usually considered that a lever escapement only transmits to the regulating organ a limited quantity of the driving force that it receives from the driving source.
  • Anchor escapements are popular for their operational reliability and are also self-starting.
  • Robin type anchor mechanisms offer the advantage of better efficiency than Swiss anchor escapement mechanisms.
  • the Robin escapement is an escapement which combines the advantages of the detent escapement (high efficiency and direct transmission of energy between the escape wheel and the balance wheel) with those of the lever escapement (better operating safety) . It is an escapement with direct impulse from the escapement mobile to the balance wheel, the anchor of the escapement mechanism essentially constituting a rocker provided with two rest pallets and which switches between two extreme rest positions of the escape wheel in outside of the impulse phases.
  • the document CH101849 A also describes a self-starting direct free escape configuration comprising at the anchor rest pallets whose rest planes are configured to interact by punctual support of the teeth of the escape mobile on the rest planes, which are in contact inclined with respect to the rest plane of said teeth.
  • This configuration has the advantage of providing a self-starting capacity for the exhaust.
  • trailing rests greatly affect the efficiency of the escapement and complicate its adjustment because at each rest there is also necessarily an induced impulse from the escape wheel on the pallets of the pallet, in addition to the main impulse. directly to the balance wheel, which significantly reduces the interest and ease of implementation on a mass industrial scale of this solution.
  • the aim of the present invention is to provide an anchor escapement which combines the respective advantages of Swiss anchor or pin anchor escapements in terms of reliability and self-starting and those of direct impulse escapements, in particular of the Robin type, and which is also made more reliable and allows serial industrial implementation of said escapement without major adjustment difficulties for the watchmaker.
  • the invention also aims to provide an exhaust that is perfectly secure against shocks and the risks of induced shutdown of the regulating organ, even in the event of micro-pulses.
  • the invention aims to propose a timepiece comprising such an escapement mechanism.
  • the present invention proposes an anchor escapement mechanism according to claim 1, as well as a timepiece provided with such an escapement and defined in claim 9.
  • the exhaust mechanism of the invention is, however, characterized in relation to the exhausts known from the prior art in that it associates and combines with the classic route of a direct exhaust a portion of the route of an indirect exhaust, as in a classic Swiss lever escapement.
  • the escape mechanism of the invention is such that at least each tooth of the escape wheel or at least one of the entry or exit pallets comprises, in the extension of its rest plane, a inclined plane arranged to provide an indirect impulse to said regulating member during a movement of said pallet in the trajectory C of the exhaust mobile by rotation of the anchor on its axis.
  • the escapement mechanism of the invention has a “hybrid” character resulting from the combination of the contours of a Swiss anchor escapement, which provides traction and is self-starting, with the contour of a direct free escapement, such as for example a Robin type exhaust.
  • the performances of the escapement of the invention are similar to those of a direct free escapement of the Robin type because all the energy transmission is done directly from the escapement mobile to the balance wheel.
  • the entry and exit pallets of the anchor being essentially only useful for rest.
  • the inclined planes of micropulses at the ends of the paddles or teeth of the mobile escapement are oriented and dimensioned such that they only participate in the self-starting of the escapement under the driving torque of the train of a watch movement, in order to transmit the initial impulse without blocking the teeth of the mobile plane on plane with the rests of the entry-exit pallets.
  • the rests are rests plane on plane, without friction or parasitic dragging impulse, therefore with significant loss of energy as known from CH101849A .
  • the ends of said inclined plane delimit with respect to said axis of rotation of the anchor an angle ⁇ , which is advantageously between 0.5 and 5°, preferably between 0.5 and 2°.
  • said inclined plane extends in a secant direction forming an acute angle i of between 30° and 70°, preferably between 40° and 60°, more preferably of the order of 50° with said plane of rest.
  • the fork comprises two horns separated by a notch and is devoid of a stinger or the like.
  • the anti-rollover securing of the anchor relative to the regulating member is advantageously achieved by the arrangement of said horns of the fork symmetrical with respect to a straight line passing through the axis of rotation of the anchor and the center of the notch and extending from said notch along an arc of a circle with a radius of curvature R1, slightly greater than the radius of gyration of the ankle, and comprising at their free end a stud or finger projecting perpendicularly to the median plane of the anchor in from which the horns extend.
  • the mechanism also comprises, according to a particular embodiment, a circular flange capable of being secured to said regulating member, said flange being centered on the axis of rotation of said regulating member, the pin being integrated into said collar of such so that it moves without contact along an internal face of said horns during the rest phases of the escapement mobile.
  • the collar whose geometry may vary, has the function of providing a contact surface for the pads in the event of an impact during the additional arc of the regulator, said pads then coming to abut either on the inside or on the exterior of said collar.
  • the radius of curvature R1 is between 0.5 and 1.5 cm.
  • said collar has free ends beveled along a vertical plane or curved.
  • the present invention also proposes in a second object a timepiece comprising an escapement mechanism as previously stated, arranged to cooperate with a regulating member to which said ankle and said impulse pallet are integral.
  • the timepiece of the invention may comprise a regulating member of the sprung balance type or of the resonator type mounted to move in rotation on a virtual pivot with knife(s).
  • the present invention proposes a free exhaust mechanism 1 of a new type, designed and arranged to exploit and combine, in a direct impulse free exhaust, the advantages of reliability, simplicity of adjustment and self-starting of a Swiss lever escapement well known to watchmakers for decades.
  • FIG. 1 A particular example of realization of such an escape mechanism 1 is shown in figure 1 , corresponding to the dead center of the exhaust 1.
  • the exhaust mechanism 1 is structurally similar to a Robin type exhaust but modified in different aspects as described below.
  • the escapement mechanism comprises an escapement mobile 2 provided with pointed teeth 3 and mounted to rotate around a first axis of rotation X1.
  • this escapement wheel 2 is associated with an escapement pinion (not shown) by which the escapement wheel 2 is coupled to the finishing train and the driving source of a watch movement, for example a spring of barrel, which thus transmits a motor torque to the escapement mobile 2, which the latter distributes sequentially to a regulating member 5 mounted movable in rotation around a second axis of rotation X2, in cooperation with an anchor 4, itself mobile in rotation around a third axis of rotation X3, the axes of rotation X1, X2, X3 being parallel to each other.

  • the escapement wheel 2 is coupled to the finishing train and the driving source of a watch movement, for example a spring of barrel, which thus transmits a motor torque to the escapement mobile 2, which the latter distributes sequentially to a regulating member 5 mounted movable in rotation around a second axis of rotation X2, in cooperation with an anchor 4, itself mobile in rotation around a third axis of rotation X3, the axes of rotation X1,
  • the regulating member 5 can consist of a sprung balance well known to those skilled in the watchmaking profession or any other oscillating regulating member, such as for example a knife resonator(s) as proposed by the applicant in the application for patent WO 2016/012281 .
  • the anchor 4 acts as a rocker and comprises a board 41 on which are arranged an entry pallet 10 and an exit pallet 11, each having a rest plane 10p, 11p intended to alternately form a rest surface in abutment for the teeth 3 of the escapement mobile 2 in two extreme positions in rotation of the anchor 4 around its axis X3, called rest positions.
  • said anchor comprises a fork 43 disposed at the end of an arm 42 extending from the plate 41 along a straight line connecting the axis of rotation X3 of the anchor 4 to the axis of rotation similar.
  • These horns 44, 45 are symmetrical with respect to the line connecting, at neutral point, the axis of rotation X3 and the axis X2 of the regulator, which also passes through the center of the notch 46.
  • the anchor 4 cooperates by this fork 43, more particularly at the level of its notch 46, with a pin 6 mounted integral with the regulating member 5, for example a coaxial plate of said regulating member 5 and to which is also secured a direct impulse pallet 9 which is propelled, at each alternation of the regulator 5 by a tooth 3 of the escapement mobile 2.
  • the travel of the anchor is limited by two pins 7, 8 which limit the angle ⁇ of travel of the anchor 4 between 5 and 6° relative to axis X3 of anchor 4.
  • the inlet pallet 10 and the outlet pallet 11, in any case at least the outlet pallet 11, comprise, in the extension of their respective rest planes 10p, 11p, an inclined indirect impulse plane 10i , 11i arranged to provide an indirect micro-pulse to the regulating member 5 when said pallets 10, 11 cross the trajectory C defines by the end of the teeth 3 of the rotating escapement mobile 2, during the rotation of the anchor 4 on its axis X3 between the two rest positions.
  • inclined planes 10i, 11i are advantageously formed on the rest pallets 10, 11 such that an angle ⁇ , called micro-pulse angle, of a value between 0.5° and 5°, more particularly in the The example shown between 1° and 2°, preferably of the order of 1.5°, is formed between its ends and the axis of rotation X3 of the anchor 4.

  • the indirect micro-pulse planes 10i, 11i provide a break or a localized shift d, in the extension and at the end of the rest planes 10p, 11p of a length determined as a function of the angle ⁇ of micro -impulse, calculated and adapted to ensure the automatic start of a regulating member associated with the exhaust 1 under the driving force of the train after the stopping of said regulating member.
  • the resting planes 10p, 11p of the pallets 10, 11 and the teeth 3 are such that they rest plane on plane in the rest position of the exhaust.
  • the center distance between the anchor pivot X3 and the pivot rests by its rest plane substantially on the detachment point d, in order to ensure that the motor torque alone induces a sufficient pull to cause said end of the tooth 3 to tilt onto the micro-impulse plane 10i, 11i after stopping the regulatory body 5.
  • the entry and exit pallets 10,11 of the anchor 4 are advantageously adjusted on the plate 41 such that the rest and release functions of the anchor with respect to the mobile of exhaust 2, as well as the running safety thereof with respect to said pallets are optimized.
  • the pallets 10, 11 are thus positioned such that in the rest positions a first of the pallets is in contact with a tooth 3 of the escapement mobile on its rest plane over a distance defining a rest angle ⁇ of the order by 2° to the axis of rotation by 1.5° to the axis of rotation X3.
  • the pallets 10, 11 provide, through their configuration and positioning, a slight pull, their inclined planes 10i, 11i providing a self-starting nature to the mechanism of the invention and the micro-pulse at each alternation, characteristics of a Swiss lever escapement.
  • an essential condition of the mechanism of the invention is defined such as : ⁇ 2 ⁇ ⁇ ⁇ ⁇
  • the inclined plane of indirect impulse can be provided not on one of the inlet 10 or outlet 11 pallets of the anchor 4 of the escape mechanism 1, of the Swiss anchor escapement type but directly on the free radial end of the teeth 3, in the form of an inclined plane 3i similar to the inclined plane 10i, 11i of the pallets 10, 11 on the figures 2 And 3 pin escapement type and thus forming a micro-impulse angle ⁇ , of a value between 0.5° and 5°, more particularly in the example shown between 1° and 2°, relative to the axis X3 of the anchor.

  • the center distance between the anchor pivot X3 and the pivot rests by its rest plane substantially on the detachment point d, in order to ensure that the motor torque alone induces sufficient pulling of the pallets 10, 11 to tilt said end of the tooth 3 onto the micro-impulse plane 3i after shutdown of the regulatory body 5.
  • the pallet 9 may finally include an end shape adapted to receive and cooperate with the inclined plane 3i of the tooth 3 during the direct impulse so as to transmit a substantially constant torque.
  • the exhaust mechanism 1 of the invention proposes an anti-overturning safety device formed in a combined manner on the fork 43 of the anchor 4 and on the regulating member 2, more particularly a collar made integral with the regulating member 5.
  • the fork 43 of the anchor 4 does not have a sting between its horns 44, 45 Indeed, the small angular path ⁇ traveled by the anchor 4 does not allow us to envisage, as initially planned in the Robin escapement, the implementation of such a dart cooperating with a small balance plate according to the usual form of a Swiss anchor escapement for example, the difficulty of adjusting the escapement to avoid the risk of bracing being too great to make the escapement viable at an industrial level.
  • the fork 43 of the anchor 4 of the mechanism 1 of the invention comprises two horns 44, 45 symmetrical with respect to a straight line passing through the axis of rotation X3 of the anchor and the center of the notch 46 and which extend from said notch 46 along an arc of a circle with a radius of curvature R1, advantageously between 0.5 and 1.5 cm or more empirically slightly greater than the radius of gyration of the pin 6 secured to the regulating member 5 by relative to the axis of rotation X2 thereof.
  • Said horns 44,45 further comprise at their free end a cylindrical stud or finger 44e, 45e projecting perpendicularly to the median plane of the anchor 4 in which the plate 41, the arm 42 and the fork 43 extend.

  • the anti-rollover device also comprises a circular flange 12 extending on either side of the pin 6 on the regulating member 5.
  • Said flange 12 is centered on the axis X2 of rotation of the regulating organ.
  • the total length of the flange 12 is preferably substantially equal to the total distance between the studs 44e, 45e of said horns 44, 45.
  • returns ( figures 18 , 21 ) of the flange 12 and the pin 6 between the horns in a normal operating configuration is ensured by the free ends of the flange 12 which are advantageously beveled along a vertical plane in order to allow said studs 44e, 45e to pass to return between the horns 44, 45 after having, if necessary, switched to the outside of the horns during the previous alternation.
  • This arrangement and conformation of the horns 44, 45 and the collar 12 thus provides optimal security against possible overturning, without negatively disrupting the operation of the exhaust mechanism 1.
  • THE figures 4 to 15 represent the different phases of operation of the escapement mechanism of the invention on two successive alternations of the regulating member 5, the respective directions of rotation of the escapement mobile 2, of the anchor 4 and of said regulating member being represented by arrows F1, F2, F3 on a first alternation respectively and arrows F4, F5, F6 on a second alternation respectively.
  • FIG 4 represents mechanism 1 in the release position.

  • the regulatory body 5 receives ( Figure 6 ) its direct impulse to the pallet 9 by the exhaust mobile at the end of which ( Figure 7 ) the fork falls ( figure 8 ) against the pin 7 and the anchor 4 is in the rest position, a tooth 3 of the escapement mobile 2 rests on the rest plane of the output pallet 11.
  • the regulating member 5 then travels its additional arc ( Figure 9 ) and the anchor 4 undergoes a pull via its output pallet 11 against the pin 7.
  • the regulating member 5 then returns in the opposite direction along F6 towards the release position ( Figure 10 ) on the second alternation, thus releasing anchor 4 from pin 7, the anchor pivoting along F5. then, passing through neutral ( Figure 11 ) undergoes a second indirect micro-pulse to the output pallet 11 ( Figure 12 ) while the escapement mobile is released in rotation according to F4, after which the anchor 4 falls on the pin 8 ( Figure 13 ), then reaching the second rest position ( Figure 14 ) or a tooth 3 of the escapement mobile comes into abutment on the rest plane of the input pallet 10.
  • the regulating member 5 then continues its stroke following F6 by making a wasted stroke until the end of its second alternation and then return following F1 to the release position of the Figure 4 .
