Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, a regulating member for a timepiece.
  • a watchmaking regulating member typically comprises an inertia flywheel mounted on an axis, this flywheel being for example a rocker or another form of oscillating mass.
  • a spiral spring is also fixed to the same axis, typically via a ferrule integrally formed with the spring or which is integral with its inner end.
  • the integration of the ferrule with the axis is usually performed by driving the axis in a receiving zone that includes the ferrule, said zone being conformed to this purpose. This hunting deforms the material of the ferrule elastically and the stresses thus generated serve to tighten the axis.
  • the two elements are thus made integral with one another.
  • the material of the component typically undergoes a slight plastic deformation in addition.
  • This method of attachment is ideal for metal or polymer components that are relatively resilient and can undergo plastic deformation without breaking.
  • brittle materials have become commonplace in watchmaking. These materials have little or no plastic field and are therefore extremely fragile.
  • this ferrule of the prior art requires an experienced watchmaker to adjust the angular relationship of the ferrule relative to the axis to ensure the proper indexing of the ferrule relative to the pendulum plate. Incorrect adjustment of this angular relationship is harmful for walking and isochronism of the regulating organ and should be avoided.
  • the use of an experienced watchmaker to perform this task is inefficient for production and is uneconomical.
  • the document JP 2014/190816 discloses a ferrule having an opening adapted to receive a non-circular section of the axis of the balance. Immediately adjacent to the protruding portion of this axis are blades delimited by slots in the body of the ferrule. These blades form embedded beams at each of its respective ends.
  • the document specifies that there is a space, and therefore a game, between the non-circular part of the axis and the ferrule. The presence of these blades seems to be for the purpose of damping shocks, but this document is not entirely clear on this point.
  • the object of the invention is therefore to provide a watch component in which the aforementioned defects are at least partially overcome.
  • the invention relates to a regulating member for a watch movement.
  • This regulating member comprises a flywheel such as a rocker, integral in rotation with an axis extending in an axial direction and a spiral spring fixed on said axis via a ferrule integral with an end of said spring.
  • the ferrule can thus be fixed on the end of the spring or integral with the latter.
  • the ferrule comprises a receiving zone arranged to receive said axis, this receiving zone being delimited at least partially by a positioning surface and at least two holding surfaces, at least one of which is displaceable against a restoring force, provided, for example, by an elastic arm having a free end, or the like.
  • These holding surfaces are arranged to clamp said axis against said positioning surface to make the ferrule and the axis integral with one another. It is noted that the tightening thus defined involves a direct contact between the holding surfaces and the positioning surface, without the interposition of other elements. In doing so, manufacturing tolerances can be very tight because there are only two elements involved, which maximizes the manufacturing accuracy and the relative positioning of the two elements.
  • the axis comprises a section of non-circular cross section, said holding surfaces as well as said surface of positioning cooperating with said section to tighten the latter.
  • the section is the part of the axis that interacts with the shell to make these two elements integral with each other.
  • This section of non-circular section (considered at a non-zero angle to said axial direction) can occupy part or even the entire length of the axis, and provides a reference for indexing the ferrule automatically with respect to the 'axis. Any subsequent step of manual adjustment of the angular orientation of the ferrule with respect to the axis is thus rendered superfluous, which simplifies manufacture and thus reduces the associated costs.
  • other non-circular shapes angular, curved, polygonal, oval, irregular and any combination thereof
  • the section comprises at least one flat which cooperates with one of said surfaces, preferably with said positioning surface.
  • a flat is easier to manufacture than other more complex non-circular shapes, and thus provides a simple solution for automatic indexing of the ferrule with respect to the section.
  • At least one, preferably each, of said holding surfaces is carried by an elastic arm that comprises said ferrule.
  • at least some (ideally all) elastic arms each have a free end, and are therefore connected to the ferrule at one of its respective ends.
  • said holding surfaces are each carried by a finger, the fingers extend towards each other from respective ends of each of said elastic arms. At least one of said elastic arms can be folded inward, which gives them increased elasticity and allows the ferrule to act as an antilock to cushion shocks in certain directions.
  • the ferrule is integral with said spring.
  • the ferrule-spring assembly is thus optimized for monoblock manufacturing by the micromechanical machining processes commonly used.
  • said shell and said section are arranged to be integrated with each other by means of an elastic driving.
  • a mounting of the ferrule on the axis according to the most common method in the watch industry is thus possible.
  • said receiving zone comprises a first sub-zone shaped so as to allow the insertion of said axis in said axial direction and a second sub-zone adjacent to and in communication with said first sub-zone, said second sub-zone. zone being arranged to clamp said section, said holding surfaces and said section being arranged so as to allow said axis to be moved laterally (that is to say at a non-zero angle, in particular perpendicular to said axial direction ) in translation from said first sub-area to enter and close to said second sub-area.
  • the axis can thus be inserted without (or with little) contact with the shell and is secured to the section via a clipping in the second sub-area. This arrangement causes less wear of these components during assembly compared to conventional driving.
  • the first sub-zone is shaped such that said axis can take place inside this sub-zone without causing displacement of said holding surfaces. Any risk of wear when inserting the axis into the receiving area is avoided.
  • said first sub-area is defined by said holding surfaces and two horn-shaped bodies preferably extending symmetrically from the holding surfaces.
  • said section and said reception zone are shaped so as to allow insertion of the axis in said axial direction when said axis and said ferrule have a first relative angular orientation, and to clamp said section against said positioning surface. when said ferrule and said axis have a second relative angular orientation distinct from said first orientation.
  • the axis carries a locking element arranged to pass through said receiving zone when said axis and said ferrule are oriented according to said first relative angular orientation as well as to block said ferrule axially on said axis when said axis and said ferrule are oriented according to said second relative angular orientation.
  • This locking element advantageously has at least one lug arranged to lock said ferrule axially on said axis when the axis and the component are oriented according to said second relative angular orientation.
  • a substantially polygonal shape whose vertices constitute said lugs is particularly suitable for this function.
  • said section has a height parallel to said axial direction which is between 100% and 120%, preferably between 101% and 115%, of the thickness of said shell considered in the same direction. If the section is machined in a cylindrical portion of the axis, the edges of the section may act as shoulders to position the component along the axis.
  • the regulating member further comprises a rocker plate mounted on said axis, said plate being indexed with respect to said axis via an additional section of non-circular shape that includes said axis.
  • the indexing of the entire regulating member can thus be ensured without subsequent adjustment by an experienced watchmaker.
  • the invention also relates to a timepiece comprising a regulating member according to one of the preceding claims.
  • the figure 1 represents a first embodiment of a portion of a regulating member 1 according to the invention, seen in partial section.
  • the regulating member 1 comprises a flywheel such as a rocker (not shown so as not to overload the figures) mounted integral in rotation with an axis 3 extending in an axial direction Z, of which only the section 5 which cooperates with a ferrule 7 integral with a spiral spring 9 is shown here.
  • the section may be machined in the body of the axis 3, or may extend all along the latter according to the wishes of the manufacturer.
  • only the root 9a of the spiral spring 9 has been shown here, the rest of the latter taking any known shape.
  • the ferrule 7 has a hollow receiving zone 11 arranged to receive and clamp the section 5 of the axis 3.
  • This zone 11 is delimited at least partly on the one hand by a positioning surface 13, on the other hand, by at least two holding surfaces 15 which are subjected to a force of elastic return.
  • the positioning surface 13 is formed on a portion of the ferrule 7 which is adjacent to said root 9a, which may be hollow or solid.
  • the holding surfaces 15 are carried by resilient arms 17 which extend from the root 9a of the spring 9, and the positioning surface 13 is substantially rigid. In other words, the positioning surface is substantially indestructible with respect to the root of the hairspring.
  • the resilient arms 17 are folded inwardly to impart increased elasticity, and thus may admit some shocks in the plane of the shell 7 in a direction other than to the positioning surface 13. also applies to the embodiments of the Figures 4a, 4b and 5 described below.
  • the ferrule 7 is thus formed by at least the root 9a of the spring 9 and the elastic arms 17 and is advantageously integral with the spring 9.
  • the section 5 of the shaft 3 has a shape arranged to be clamped by the holding surfaces 15 against the positioning surface 13 following an elastic driving of the shell 7 on the axis 3.
  • This section 5 is also arranged for angularly indexing relative to the positioning surface 13. To this end, it has a shape complementary to that of the positioning surface 13, these complementary shapes ensuring the indexing of the section 5 with respect to the ferrule 7.
  • the section 5 comprises at least one flat 19 intended to be in contact with said surface 13.
  • other non-circular shapes are possible, such as a lug or a finger which cooperates with a notch of complementary shape constituting the positioning surface 13, irregular shapes or any other form allowing such indexing. This generally applies to all embodiments of the invention.
  • the rest of the periphery of the section 5 is shaped to cooperate with the holding surfaces 15 in order to allow the ferrule 7 to be driven on the axis 3 in a known manner.
  • the indexing of the section 5 and therefore of the axis 3 relative to the ferrule allows that it can also be indexed with respect to a plateau (see below) without requiring manual adjustment of the angular relationship of these components.
  • the assembly of the regulating member is thus simplified and any further development by a qualified watchmaker is avoided.
  • the figure 2 illustrates another embodiment of a regulating member 1 according to the invention, which has the same advantages as that of the figure 1 .
  • the receiving zone 11 is shaped so as to allow clipping of the section 5 in a direction perpendicular to said axial direction Z, that is to say in the plane of the ferrule 7.
  • the receiving zone 11 of the ferrule 7 is defined by the distal portions 17a of the elastic arms 17 which extend from the root 9a of the spring 9 and divide into two sub-zones.
  • the first sub-zone 11a is the furthest away from the root 9a of the spiral spring 9 and is shaped to allow insertion without driving of the axis 3 and its section 5 in said axial direction Z. For this purpose, it is delimited by horn-shaped bodies extending symmetrically from the holding surfaces 15, this symmetry is not mandatory.
  • the second sub-area 11b is adjacent to, and in communication with, the first 9a. The latter is delimited at least partially by the holding surfaces 15, which are formed as beaks extending towards each other from the distal portions 17a of the elastic arms 17 and by holding surfaces 13.
  • the positioning surfaces 13 are carried by tabs 17b extending from the distal portions 17a of the elastic arms towards the root 9a of the spring 9, and which are folded to form stops for the flat portion 19 of the section. It goes without saying that other forms of positioning surface are also possible, more or less rigid, which extend from the root 9a or from the elastic arms 17, according to the wishes of the manufacturer. Furthermore, it is also possible to provide only one holding surface 13, having an ad hoc form.
  • the arrangement of positioning surfaces 13 and holding surfaces 15 and the elastic arms 17 are configured such that when the axis 3 is inserted in the first sub-zone 11a and is displaced in translation towards the root 9a , the shape of the section spreads the surfaces of 15 and bends the elastic arms 17.
  • the section 5 can thus enter the second sub-area 11b.
  • the elastic arms remain bent in order to provide a clamping force that tends to clamp the section 5 against the positioning surfaces 13. It is emphasized here that this clamping is by definition direct, without the interposition of other elements whose presence would prevent both surfaces to be positioned against each other. Manufacturing tolerances can therefore be reduced to a minimum value.
  • the first sub-area 11a is defined by curved ends of a pair of elastic arms 17 extending symmetrically from the frame of the shell 7 towards a positioning surface 13 which is, in the variant shown, a curved notch but which can be flat.
  • the distal ends of the elastic arms 17 are free, in order to provide sufficient elasticity to the latter.
  • the axis 3 can be inserted into the first zone 11a with play (or with a slight contact with the elastic arms 17). Then, by moving the axis towards the positioning surface 13, the shape of the section 5 spreads the ends of the elastic arms and flexes the arms 17 (see FIG. figure 3b ). An abutment surface 21 having a shape complementary to that of the positioning surface 13 abuts against the latter when the section 5 is in the second sub-area 11b.
  • the ends of the elastic arms 17 are fingers that constitute the holding surfaces 15 and act on the flats 19 to position the section 5 angularly and to clamp the latter against the positioning surface 13.
  • the section 5 may comprise a single flat 19 for cooperating with a positioning surface 13, the holding surfaces 15 thus cooperating with surfaces of the section 5, which can be curved or not.
  • three flats, each cooperating with one of said surfaces 13, 15 may also be used and a large number of other forms of the section, regular or irregular, are also conceivable.
  • the ferrule 7 can also be detached from the axis 3 by displacing the latter in translation to the first subarea and by removing it in the axial direction Z.
  • FIGS. 4a and 4b illustrate yet another embodiment of a regulating member 1 according to the invention which has the same advantages as that of the figure 1 .
  • the receiving zone 11 and the section 5 are shaped so that the axis 3 can be inserted in said axial direction Z and is subsequently tightened against the positioning surface 13 by the holding surfaces 15 by pivoting the axis 3 relative to the ferrule 7.
  • the positioning surface 13 is part of the root 9a of the spring and is substantially rigid and the elastic arms 17 which carry the holding surfaces 15 extend on either side of the root 9a to surround partially to zone 11.
  • each of the arms 17 is folded inwards and the folded parts carry the holding surfaces 15.
  • the receiving zone 11 and the shape of the section 5 are complementary and have a relationship such that, in a first angular orientation relative to these two elements, the axis 3 can be inserted in the zone 11 in said axial direction Z.
  • This relationship is illustrated on the figure 4a in solid lines and shows that there is enough clearance for the section 5 does not come into contact with the ferrule 7 when inserted into said zone in a direction parallel to the axis 5. Alternatively, a slight contact between the axis 5 and the surfaces 11 and 13 may be allowed.
  • the periphery of the section 5 abuts against the holding surfaces 15, which are displaced against the restoring force provided by the elastic arms 17.
  • the angular relationship between these components at that time is illustrated on the figure 4a in dotted lines, in which a corner of the section 5 is in contact with the positioning surface 13.
  • the positioning surface 13 may comprise a notch 23 which allows a corner of the section 5 to enter during rotation of the axis 3 relative to the ferrule 7.
  • the displacement of the holding surfaces 15 and also the stresses generated in the arms 17, can be limited.
  • the axis 3 adopts a stable position in a second relative angular orientation illustrated in solid lines on the figure 4b this angular orientation being distinct from the first angular orientation mentioned above.
  • this position the holding surfaces 15 have been raised by the shape of the section 5 and the elastic arms 17 are thus constrained (solid lines, the initial position of the elastic arms 17 and the section 5 is illustrated in dotted lines), and tighten the section 5 against the positioning surface 13.
  • the section has a shape having a flat 19 which is positioned against the positioning surface 13 (which is also flat with the exception of the notch 23) in the service position and two rounded corners
  • the flat 19 is arranged to be in contact with the holding surfaces 15.
  • the flat 19 is bonded to the rounded corners 25 by plane surfaces.
  • the illustrated embodiment is therefore not limiting.
  • the section 5 may have angular, curved, polygonal, oval, irregular shapes and any combination thereof.
  • the holding surfaces 15 may take the form of jumpers, fingers, tongues or any other suitable form.
  • the elastic restoring force for these surfaces it can be provided by elastic elements of any kind which are integral with said surfaces or which are constituted by additional elements provided on the shell 7.
  • the positioning surface 13 may be curved, angular, irregular or any other suitable form. Indeed, any combination of forms of the surfaces 13, 15 and of the section 5 which allows a stable tight angular position and an angular position allowing the axis 5 to enter the receiving zone 11, substantially without displacement of the holding surfaces 15, is suitable for the implementation of the invention.
  • the figure 5 further illustrates a variant of a regulating member 1 according to the invention, which operates in a manner similar to that of the Figures 4a and 4b .
  • This embodiment differs from that of Figures 4a and 4b in that only a first of the holding surfaces 15a, 15b is displaceable against an elastic restoring force.
  • the other of the holding surfaces 15b is carried by a substantially rigid arm 17b which extends from the root 9a of the spring 9 and is adjacent to the positioning surface 13.
  • the first holding surface 15a is carried by the end of an elastic arm 17a extending from the root 9a of the spring 9 and partially enclosing the section 5 and the substantially rigid arm 17b; it should be noted that the elastic arm 17a could also not partially surround the substantially rigid arm 17b if it rushed from the root 9a in the other direction.
  • this elastic arm 17a therefore forms a finger that carries the first holding surface 15a, the latter bearing against the section 5 to clamp the latter against the positioning surface 13 and against the second holding surface 15b.
  • the latter serves as a guide stop which has the effect that the section 5 is clamped against the positioning surface 13, which is oblique with respect to the direction of the force provided by the single elastic arm 17a and therefore requires a guide section 5 through the second holding surface to perform the clamping.
  • the receiving zone 11 is at least partially defined by the surfaces 13, 15a and 15b, the section 5 having a section of complementary shape for the insertion of the axis 3 in said zone 11 in the axial direction Z when the axis 3 and the shell 7 are in a first relative angular orientation (illustrated in dashed lines).
  • the rounded corner 25 of the section 5 raises the first holding surface 15a and flexes the elastic arm 17a.
  • the elastic arm 17a remains bent and clamps the section against the positioning surface 13 and against the second holding surface 15b.
  • the angle between the first angular orientation and the second angular orientation is 60 °, but any suitable angle may be used.
  • the edges of the section 5 may constitute shoulders which serve as stops to prevent the movement of the shell 7 the along the axis when it is tight.
  • the section 5 does not extend all along the axis 3 but occupies a length lying between 100% and 120%, preferably between 101 and 115% of the thickness of the shell 7.

  • the figure 6 more fully illustrates a portion of a regulating member 1 according to the invention, the flywheel (such as a rocker) not shown so as not to overload the drawing.
  • the flywheel such as a rocker
  • the section 5 is delimited on the one hand by a conventional shoulder 27, and on the other hand by a locking element 29.
  • This element 29 is shaped to form at least one axial stop when the axis 3 and the shell 7 are in their second relative angular orientation, and to be able to pass through said zone 11 when the axis 3 and the shell 7 are in their first relative angular orientation.
  • the locking element 29 forms an axial abutment when the axis 3 and the shell 7 are in a first position 11a and in order to pass through the receiving zone 11 when the axis 3 and the shell 7 are in a second position 11b.
  • the illustrated locking element 29 has a truncated triangular shape 31 truncated.
  • These peaks 31 constitute lugs which can pass through said zone 11 in said first angular orientation, and serve as stops to prevent the removal of the ferrule 7 from the axis 5 when these components are in their second orientation.
  • the locking element 29 and the shoulder 27 thus block the component 3 axially on the axis 5.
  • other forms of locking element 29 are possible, which comprise at least one lug 31 or projecting projection arranged to form an axial stop when the axis 3 and the shell 7 are in their second angular orientation.
  • the other end of the axis 3, opposite to that carrying the ferrule 7, has an additional flat portion 31 (or any other appropriate non-circular shape provided on an additional section of the axis) which serves for indexing a balance plate 33.
  • This plate 33 is attached to the axis in the same way as the ferrule 7 in the embodiment of the figure 2 , the flat 31 indexing the axis relative to the plate 33 by its interaction with the positioning surfaces 13.

  • the plate 33 comprises a peg 35 whose flanks are continued by elastic arms 17 which provide the restoring force so that the holding surfaces 15 tighten the axis 3.
  • the ends of the elastic arms 17 which define the receiving zone 11 including sub-areas 11a and 11b have a greater height than that of the peg 5, which serves to position the plate 33 relative to an additional shoulder 36, and to confer at the ends increased rigidity.
  • the section 5 always has at least one line of symmetry, but it is also possible that its shape is irregular.
  • the elastic arms 17, 17a, 17b of the variants of the Figures 1-4b and 6 which have been represented in symmetrical shapes, can also be different from one another and asymmetrical. Indeed, it is not important that the forces exerted by the holding surfaces are identical or are exerted symmetrically.
  • the principle of the invention is particularly advantageous when the component 2 is made of brittle material as mentioned in the preamble, it also applies to components 3 of metal or metal composite or conventional polymer.
