Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, an escapement anchor escape mechanism pulsing separate rest from the rest by means of a rest fork adapted to be arranged in kinematic connection with a timepiece control member.
  • the invention furthermore relates to a timepiece comprising such an escapement mechanism cooperating with a suitable regulating organ, in particular of the spiral balance type or the knife oscillator.
  • the object of the present invention is to provide a new improved performance rest anchor escapement comprising a minimal lift angle on the body regulator in order to make it viable for use in a watch movement of a mechanical watch but which does not suffer the limitations of known rubbing rest exhausts.
  • Another object of the invention also relates to the proposal a timepiece comprising such an escapement.
  • the escape mechanism further comprises at least one pulse pallet adapted to be fixed on a said regulating member for transmitting a pulse by sliding a tooth of the escapement mobile on a plane of pulse of said impulse pallet once at least every two alternations of said regulating member while the rest anchor comprises a kinematic connecting member permanently rotatable to said regulating member so as to provide a lever arm between the axis rotation of the regulating member and the escape wheel.
  • the escapement mechanism of the present invention is thus similar to a Graham type escapement, commonly used in clocks, but with a rest anchor distinct from the impulse pallet (s). ) -even apt (s) to be secured (s) on a timepiece regulating member, including a balance spring balance spiral as commonly used in watches or type resonator knife described in the patent application WO2016 / 012281 of the Applicant.
  • the escape mechanism of the invention may also advantageously be a blow-by-blow escapement, which reduces the "trailing" pulse phases to one pulse every two half-cycles of the regulating member, while ensuring periodic clearances at the desired frequency of the regulating organ.
  • the escapement mechanism of the invention is further secured by the permanent link provided from the rest anchor to the regulating member, which prevents any overturning and jamming in small angular ranges of movement of the regulating member.
  • the rest anchor and the at least one pulse pallet are arranged vis-à-vis the mobile escape so that, in a position called "dead point", that is to say outside phases of rest or impulse, the pallets of rest are located at a distance from the axis of rotation of the escapement mobile greater than the radius of the circle circumscribed to the teeth of said mobile escape then at least one end of the at least one pulse pallet is located at a distance from the axis of rotation of the escapement less than said radius. Consequently, it is clearly understood that in a neutral position, the rest pallets are spaced apart from the teeth of the escape wheel at the periphery thereof, while the at least one of the impulse pallets extends at least partially between said teeth of the exhaust mobile.
  • This particular escape arrangement makes it possible in particular to ensure a self-starting character to the escapement mechanism of the present invention since the torque of the regulating member is sufficient, by virtue of the lever arm provided by the rest anchor between the axle. of rotation of the regulating member and the escapement mobile to disengage the escapement mobile, which will be able to engage a pulse plan of a pulse pallet under the driving action of the finishing gear train. a watch movement to which it is associated without contact with the pallet rest, previously released by the rotation of the rest anchor induced by the regulating member.
  • the teeth of the escapement mobile have a greater thickness, substantially double, for example, to that of the serge of the escapement mobile from which they extend. This makes it possible in particular to ensure, during the pulse phases, a secure support of a tooth on the pulse plane of a pulse pallet and the free passage of a said pulse pallet above the serge between two teeth during the course of the additional arc of the regulator member on which said pulse pallet is to be arranged using the inventive escape mechanism in a timepiece.
  • the rest anchor comprises a permanent kinematic linkage member to a said regulator member arranged at the end of an arm extending opposite the pallets of rest, said link member comprising a slide adapted to receive a pin, stud, pin or the like intended to be fixed on a said regulating member to make a sliding pivot connection between the rest anchor and said regulating member.
  • said slide can be machined in the mass at the end of the link member of the rest anchor, for example in the form of a closed or open groove or groove, thus forming a form of connecting fork.
  • the escape mechanism has a single pulse pallet.
  • the escapement of the invention is then a blowaway escapement.
  • the exhaust mechanism comprises two impulse vanes adapted to be symmetrically fixed on a said regulator member relative to a straight line passing through the axes of rotation of said regulating and movable exhaust member.
  • the present invention also proposes a timepiece, in particular a watch, comprising a watch movement equipped with a mechanical power source, a finishing gear train, a regulating member and a mechanism exhaust system according to the invention arranged in kinematic connection by its escape mobile to the work train on the one hand and by the connecting member of the rest anchor to said regulating member a pulse pallet at least of said mechanism the escapement being furthermore fixed on said regulating member to periodically receive a proportion of mechanical energy from the driving source by trailing impulse of a tooth of the escapement wheel on a pulse plane of the pallet of 'impulse.
  • a final object of the present invention also relates to the proposal of a timepiece control member adapted to operate in conjunction with the escape mechanism described above.
  • the regulating member according to the invention may advantageously be a balance-spring assembly comprising projecting with respect to the balance rod a pulse pallet or two impulse vanes, fixed on said balance.
  • the present invention proposes a new type of escapement for timepieces comprising a rest anchor and separate pulse palettes, and arranged in such a way that the rest are separated from the pulses, in order to reduce the known problems of the escapements at train rest known from the prior art,
  • the escapement of the present invention has an extremely simple structure of construction and compactness, compatible with the use of balance-type regulating members conventionally employed in pocket watches or wristwatches but with lower amplitudes of Oscillations of the balance, and therefore higher frequencies, without significantly disturbing the isochronism.
  • a first particular embodiment of the escapement mechanism 1 of the invention is thus represented on the Fig. 1 in a so-called "dead point" position, outside impulse or rest phases.
  • the exhaust mechanism 1 is represented on this Fig. 1 (and following) in collaboration with a balance part of a regulating member 2 of the balance sprung type whose spiral is not shown and a mobile 4 of a work train of a watch movement.
  • the regulator member 2 could also be of the knife resonator type, as proposed by the Applicant in the patent application. WO 2016/012281 .
  • the Figures 2 to 9 then represent the different phases of operation of the inventive exhaust on a complete oscillation of the balance 2.
  • the escapement mechanism 1 of the present invention thus comprises in the first place an escapement wheel 3 movable in rotation about a first axis around which is also driven an exhaust pinion (not shown) for coupling the mobile exhaust 3 to a mobile terminal 4 of the gear train finishing a watch movement.
  • the escapement wheel 3 comprises a series of peripheral teeth 31 extending, in a conventional manner, from a serge 32 of the escapement wheel 1.
  • the teeth 31 have at their free end a thickness, measured in the plane of the escapement mobile 3 in which the serge 32 and the teeth 31 extend, perpendicular to the axis of rotation of the mobile exhaust 3, which is greater than that of the serge 32.
  • This difference in thickness between the teeth 31 and the serge 32 of the escapement mobile is shown schematically in the figures by a shoulder line near the foot of each tooth 31.
  • This increased thickness of the teeth relative to the rest of the mobile provides as it will be exposed by following a capacity mobile escape 3 to cooperate alternately with a rest anchor 5 and pulse pallets 21, 22 fixed on the balance of the regulating member 2 movable in parallel planes s uperposés and secants of said teeth 31.
  • the escapement mechanism 1 therefore also comprises a rest anchor 5, interposed between the balance of the regulating member 2 and the escapement wheel 3, and two impulse vanes 21, 22, advantageously fixed on the balance wheel.
  • the regulating member 2 by any appropriate means, in particular by gluing or screwing, or come from material in the mass of the pendulum during the manufacture thereof and machining.
  • the pulse pallets 21, 22 are preferably arranged on the regulating member 2 symmetrically with respect to a straight line passing through the axes of rotation of said regulator member 2 and movable exhaust member 3 in said "neutral" position. "Represented on the Fig. 1 , thus giving the regulating member 2 the appearance of an anchor.
  • These pulse palettes 21, 22 each comprise a cutting pulse plane p, in the "neutral" position ( Fig. 1 ) the circumscribed circle cc to the teeth 31 of the escapement wheel 3.
  • the rest anchor 5 comprises a first and a second pallet of rest 52, 53 respectively arranged at one end of a first and a second arm 54, 55. These rest pallets 52, 53 are adapted to engage alternately in a first and a second rest position, by displacement induced directly and exclusively by the balance of the regulating member 2, a tooth 31 of the escapement wheel 3 at each rotation step thereof.
  • the rest anchor 5 also comprises a member 51 of permanent kinematic connection to the regulating member 2.
  • Said member 51 of permanent kinematic link to the regulating member is advantageously formed at the end of an arm extending opposite the pallets of rest 52, 53 in a slide 7 adapted to receive a male sliding connection element such as a pin 6, or a stud, lug or the like driven on the regulating member 2 to achieve a sliding pivot connection between the rest anchor 5 and the regulating member 2.
  • the slide 7 can be made of various shapes. It may for example be machined in the mass at the end of the connecting member 51 of the rest anchor 5, in the form of a groove or closed, straight or Y-shaped groove to allow an amplitude stroke of the regulator up to more than 90 ° in particular.
  • it may also consist of a notch or groove, machined or formed of material in the mass of the rest anchor 5 according to the material thereof, forming a connecting fork with two teeth on either side of the notch, in which can slide the pin 6 of connection to the regulating member 2.
  • the slide 7 and the pin 6 are arranged on the rest anchor 5 and the regulating member 2 so that said pin 6 is arranged and moves, in operation of the escape mechanism 1, inside the slide 7 and is permanently in contact with the walls thereof, in all positions of the balance of the regulating member 2, as opposed to the interaction of an anchor with the rocker pin in the conventional exhaust mechanisms of the prior art.
  • the rest anchor 5 is arranged relative to the regulating member 2 and the escapement wheel 3 so that, in the neutral position of the exhaust shown in FIG. Fig. 1 its axis of rotation is parallel to the axes of rotation of the regulating member 2 and the escape wheel 3. Moreover, still in this neutral position, the rest anchor 5 must be such that the rest pallets 52, 53 are located at a distance from the axis of rotation of the exhaust movable greater than the radius R of the circumscribed circle cc to the teeth 31 of the escapement wheel 3, when at the same time the ends of the impulse vanes 21 , 22 intersect said circumscribed circle cc, and are thus located at a distance from the axis of rotation of the escapement wheel 3 less than the radius R.
  • the impulse planes p of the impulse pallets 21, 22 are located on the trajectory of the teeth 31 of the escapement wheel 3 represented by the circle cc, whereas the rest pallets 52, 53 are located outside this path.
  • the rotation of the escapement wheel 3 necessarily entails the engagement by a tooth 31 of a pulse plane p of a pulse pallet 21, 22 and the drive, by sliding of the tooth 31 on this pulse plane p, the balance of the regulating member 2 oscillating about its axis.
  • the exhaust 1 is thus self-starting, and facilitated by the lever arm effect of the rest anchor between the escapement wheel and the balance.
  • the permanent connection by the member 51 of the rest anchor 3 to the armature induces, as soon as said balance wheel is rotated, a driving moment of the rest anchor 3 about its axis applied to the contact point. between the pin 6 and the slide 7 of the member of permanent liaison.
  • FIGS. Figures 2 to 9 The operation of the exhaust mechanism of the invention on a complete oscillation of the regulating member 2 is shown in FIGS. Figures 2 to 9 and described below.
  • the directions of rotation of the balance of the regulating member, the rest anchor and the escape mobile will be qualified as clockwise or counterclockwise respectively, with reference to the planar representations of each of the figures.
  • the figure 2 represents the escapement mechanism 1 in the final pulse position of a tooth 31 of the escapement wheel 3 on the pulse pallet 21 of the regulating member 2.
  • the torque transmitted by the escapement wheel 3 to the regulator 2 via the pallet 21 rotates the latter in the clockwise direction, which corollarily causes the rotation of the rest anchor 3 in the counterclockwise direction by effect of the connection of the rear limb 51 of the anchor to the pin 6 to close to the axis of rotation of said regulating member 2.
  • This rotation of the rest anchor 3 brings the rest pallet 52 into opposition in the rest position against the tooth 31 which has just transmitted the pulse to the regulator 2, as shown to the figure 3 .
  • the pulse pallet 22 of the balance of the regulating member then follows a circular path between two teeth 31 of the escapement wheel 3, without contact with them ( Fig. 18 ), over all this alternation, corresponding to the path of the additional arc of the pendulum clockwise ( Fig. 4 ).
  • the balance is conventionally biased counterclockwise by a return spring (not shown) with which it is associated.
  • This rotation in counterclockwise direction causes rotation of the rest anchor 3 in the direction this time and the release of the pallet rest 52 of the mobile escape ( Fig. 5 ) while a tooth 31 of the latter comes to bear sliding on the pulse plane p of the pulse pallet 22 ( Fig. 6 ), thus starting a second trailing impulse to the pendulum via the escapement mobile 3.
  • the pendulum continues its clockwise rotation movement under this impulse until the end of this second impulse ( Fig. 7 ) which rotates the rest anchor 3 to bring it to a second rest position in which the second rest pallet 53 is located in opposition to a tooth of the escape wheel 3 ( Fig.
  • the Figures 10 to 17 additionally represent the operation of a variant embodiment of the exhaust mechanism 1 of the invention in which the exhaust mechanism comprises only a pulse pallet 21.
  • the figure 10 represents this second lost-shot version of the exhaust 1 of the invention in neutral, similarly to the Fig. 1 .
  • the moving wheel 4 drives the escapement wheel 3 clockwise which brings a tooth 31 of said mobile against the pulse plane p of the single pulse pallet ( Fig. 11 ) to transmit a pulse to the regulating member 2.
  • This trailing pulse rotates the regulating member 2 clockwise as well and thus the rest anchor 3 counterclockwise on its axis, thus leading to the end of the pulse ( Fig. 12 ) the rest pallet 52 in the first rest position ( Fig. 13 ) against a tooth 31 of the escape wheel 3.
  • the regulating member 2 then performs a first alternation ( Fig.
  • the regulating member 2 carrying the single pulse pallet 21 then makes its lost blow between two teeth 31 of the escape wheel ( Fig. 16 and 20 ), which, when passing through neutral, rotates the rest anchor 3 in a clockwise direction, bringing the second rest pallet 53 into a second rest position to prevent the rotation of the escape wheel during the blow and the course of the second complete alternation of the pendulum, as shown Fig. 17 , which then returns in the opposite direction in a classic way and so on.
  • the invention thus proposes a structure escapement mechanism that is simple, reliable and compact, adapted to small amplitudes of oscillations and high frequencies of the regulating member of a clock mechanism, which can be used both in watch mechanisms as clocks by singularly improving the performance of these mechanisms in comparison to slack rest exhausts known until then.
