    Description
    Technical Field [0001] The present invention relates to the field of watchmaking. It relates, more particularly, to a regulating member for a timepiece.
    STATE OF THE ART [0002] A watchmaking regulating member typically includes a flywheel mounted on an axis, this flywheel being for example a balance wheel or another form of oscillating weight. In order to provide a return torque to cause the flywheel to oscillate, a spiral spring is also fixed to the same axis, typically by means of a ferrule made integrally with the spring or which is integral with its inner end. The integration of the ferrule with the axis is usually carried out by driving the axis into a reception zone that the ferrule comprises, said zone being designed for this purpose. This hunting deforms the material of the shell elastically and the stresses thus generated serve to tighten the axis. The two elements are thus made integral with one another. During hunting, the material of the component typically undergoes a slight additional plastic deformation. A split ring ferrule may be cited as a traditional example of a ferrule serving this purpose.
    This fixing method is perfectly suitable for metal or polymer components which are relatively elastic and can undergo plastic deformations without breaking.
    More recently, brittle materials have become common in watchmaking. These materials have little or no plastic area and are therefore extremely fragile. As such, there may be cited hard steels, ceramics, glasses, vitroceramics, mono- or polycrystalline silicon, amorphous silicon, nitride oxides or silicon carbides under any crystalline regime, alumina, synthetic diamond and the like.
    Since these materials are brittle, it is very difficult, if not impossible, to drive out a ferrule made of such a material on an axis in the traditional way, while keeping acceptable manufacturing tolerances.
    For these reasons, watch manufacturers have developed several solutions for mounting components made of such materials on axes. One of these solutions is to provide elastic structures at the level of the component mounting area, these elastic structures allowing hunting without development of excessive stresses in the material of the component. These structures are typically formed in the body of the component and flex when the axle is introduced.
    As such, we can cite the document WO 2011/116 486 which describes a split ferrule comprising two elastic tongues which constrain and position the axis against a substantially rigid positioning surface when the axis is driven into the area of reception, defined by the languages and the positioning surface.
    However, this ferrule of the prior art requires an experienced watchmaker to adjust the angular relationship of the ferrule relative to the axis in order to ensure proper indexing of the ferrule relative to the plate of the balance. Improper adjustment of this angular relationship is harmful for walking and for the isochronism of the regulating organ and is to be avoided. However, using an experienced watchmaker to perform this task is inefficient for production and is uneconomical.
    The object of the invention is therefore to provide a timepiece component in which the above-mentioned defects are at least partially overcome.
    Disclosure of the invention [0010] More specifically, the invention relates to a regulating member for a clockwork movement. This regulating member comprises a flywheel such as a pendulum, integral in rotation with an axis extending in an axial direction as well as a spiral spring fixed on said axis by means of a ferrule integral with 'one end of said spring. The ferrule can thus be fixed on the end of the spring or come integrally with the latter.
    The ferrule comprises a receiving area arranged to receive said axis, this receiving area being delimited at least partially by a positioning surface as well as at least two holding surfaces, at least one of which is movable to meet a restoring force, supplied, for example, by an elastic arm or the like. These retaining surfaces are arranged to clamp said axis against said positioning surface in order to make the ferrule and the axis integral with one another.
    According to the invention, the axis comprises a non-circular cross-sectional section, said retaining surfaces as well as said positioning surface cooperating with said section in order to tighten the latter. The section is thus the part of the axis which interacts with the ferrule in order to make these two elements integral with one another.
    This non-circular section 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 shell automatically by relation to the axis. Any subsequent step of manual adjustment of the angular orientation of the shell relative to the axis is thus made superfluous, which simplifies manufacture and thus reduces associated costs. Alternatively, other forms
    CH 714 001 A1 non-circular (angular, curved, polygonal, oval, irregular and any combination of these) can be used in combination with a positioning surface of complementary shape.
    Advantageously, 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 the automatic indexing of the shell relative to the section.
    Advantageously, at least one, preferably each, of said holding surfaces is carried by an elastic arm that includes said ferrule.
    Advantageously, said retaining surfaces are each carried by a finger, the fingers extend towards one another from respective ends of each of said elastic arms. At least one of said elastic arms can be folded inwards, which gives them increased elasticity and allows the shell to act as a shock absorber to absorb shocks in certain directions.
    Advantageously, the ferrule has come integrally with said spring. The ferrule-spring assembly is thus optimized for one-piece manufacturing by the commonly used micromechanical machining processes.
    Advantageously, said ferrule and said section are arranged to be integrated with each other by means of an elastic drive. An assembly of the ferrule on the axis according to the most common method in watchmaking is thus possible.
    Advantageously, said reception zone comprises a first sub-zone shaped so as to allow the insertion of said axis in said axial direction as well as a second sub-zone adjacent to and in communication with said first sub-zone, said second sub-area 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-zone in order to make it enter into said second sub-zone and to be clamped there. The axis can thus be inserted without (or with little) contact with the ferrule and is secured to the section by means of a clipping in the second sub-area. This arrangement generates less wear of these components during assembly compared to a conventional drive.
    Advantageously, the first sub-area is shaped so that said axis can take place inside this sub-area without causing displacement of said holding surfaces. Any risk of wear when inserting the pin into the receiving area is thus avoided.
    Advantageously, said first sub-area is defined by said retaining surfaces as well as two horn-shaped bodies preferably extending symmetrically from the retaining surfaces.
    Advantageously, said section and said reception area are shaped so as to allow the 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. An insertion of the axis in the zone without (or with little) friction is thus possible, the joining of the ferrule to the axis flowing following a relative rotation between these two components. In doing so, the retaining surfaces clamp the section against the positioning surface. Again, this arrangement generates less friction and therefore less wear of the two components compared to a conventional drive.
    Advantageously, 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. The axial locking of the ferrule on the axis in the direction limited by said lug is thus ensured, regardless of the shape and length of the section. 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 in said second relative angular orientation. A substantially polygonal shape whose vertices constitute said lugs is particularly suitable for this function.
    Advantageously, 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 can act as shoulders to position the component along the axis.
    Advantageously, the regulating member further comprises a balance plate mounted on said axis, said plate being indexed relative to said axis by means of an additional section of non-circular shape that comprises said axis. Indexing of the entire regulating organ can thus be ensured without further adjustment by an experienced watchmaker.
    The invention also relates to a timepiece comprising a regulating member according to one of the preceding claims.

    Embodiment of the invention [0028] FIG. 1 shows a first embodiment of a part of a regulating member 1 according to the invention, seen in partial section.
    The regulating member 1 comprises a flywheel such as a balance (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 secured to a spiral spring 9 is shown here. The section can be machined in the body of axis 3, or can extend all along the latter according to the wish of the manufacturer. Furthermore, only the root 9a of the spiral spring 9 has been shown here, the rest of the latter taking any known form.
    The ferrule 7 includes a hollow receiving zone 11 arranged to receive and tighten the section 5 of the axis 3. This zone 11 is delimited at least partially on the one hand, by a positioning surface 13, on the other part, by at least two holding surfaces 15 which are subjected to an elastic restoring force. The positioning surface 13 is formed on a part of the shell 7 which is adjacent to said root 9a, which can be hollow or solid. In the variant shown, the holding surfaces 15 are carried by elastic 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 non-displaceable relative to the root of the balance spring.
    In this embodiment, the elastic arms 17 are folded inwardly to give them increased elasticity, and can thus admit certain shocks in the plane of the shell 7 in a direction other than towards the positioning surface 13. This also applies to the embodiments of FIGS. 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 made in one piece with the spring 9.
    The section 5 of the axis 3 has a shape arranged to be clamped by the holding surfaces 15 against the positioning surface 13 following an elastic driving of the ferrule 7 on the axis 3. This section 5 is also arranged to be angularly indexed relative to the positioning surface 13. To do this, it has a shape complementary to that of the positioning surface 13, these complementary shapes ensuring the indexing of the section 5 relative to the ferrule 7. In the illustrated embodiment, the section 5 comprises at least one flat 19 intended to be in contact with said surface 13. However, 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 shape allowing such indexing. This generally applies to all of the 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 out 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 the latter can also be indexed relative to a balance plate (see below) without requiring manual adjustment of the relationship angular of these components. The assembly of the regulating member is thus simplified and any subsequent adjustment by a qualified watchmaker is avoided.
    [0036] FIG. 2 illustrates another embodiment of a regulating member 1 according to the invention, which has the same advantages as that of FIG. 1.
    CH 714 001 A1 In this variant, the reception 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 shell 7 is defined by the distal parts 17a of the elastic arms 17 which extend from the root 9a of the spring 9 and are divided into two sub-zones. The first sub-area 11a is the furthest from the root 9a of the spiral spring 9 and is shaped to allow insertion without driving 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 not being compulsory. The second sub-area 11b is adjacent to, and in communication with, the first 9a. The latter is delimited at least partially by the retaining surfaces 15, which are formed as spouts extending towards one another from the distal parts 17a of the elastic arms 17 as well as by retaining surfaces 13. In this variant, the positioning surfaces 13 are carried by tongues 17b extending from the distal parts 17a of the elastic arms in the direction of the root 9a of the spring 9, and which are folded to form stops for the flat part 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 wish of the manufacturer. Furthermore, it is also possible to provide only a single holding surface 13, having an ad hoc shape.
    The arrangement of positioning surfaces 13 and holding 15 and the elastic arms 17 are configured so that when the axis 3 is inserted in the first sub-area 11 a and is moved in translation in direction from the root 9a, the shape of the section causes the retaining surfaces 15 to move apart and flexes the elastic arms 17. The section 5 can thus enter the second sub-area 11b. In doing so, the elastic arms remain bent in order to provide a clamping force which tends to clamp the section 5 against the positioning surfaces 13.
    Figs. 3a and 3b illustrate this principle of clipping more clearly in a different form. These drawings serve rather to illustrate schematically the principle applied in the variant of FIG. 2 and thus have less suitable shapes for a ferrule 7, the latter comprising a rigid part represented simply by a rigid frame.
    In these figures, the first sub-area 11a is defined by curved ends of a pair of elastic arms 17 extending symmetrically from the frame of the ferrule 7 towards a positioning surface 13 which is , in the variant shown, a curved notch but which may be flat.
    As mentioned above, the axis 3 can be inserted into the first zone 11a with play (or with slight contact with the elastic arms 17). Then, by moving the axis in the direction of the positioning surface 13, the shape of the section 5 spreads the ends of the elastic arms and bends the arms 17 (see fig. 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 located in the second sub-area 11b. The ends of the elastic arms 17 are fingers which constitute the holding surfaces 15 and act on the flats 19 in order to position the section 5 angularly and to clamp the latter against the positioning surface 13. Alternatively, the section 5 may comprise a single flat 19 intended to cooperate with a positioning surface 13, the retaining surfaces 15 thus cooperating with surfaces of the section 5, which may or may not be curved. Of course, three flats, each cooperating with one of said surfaces 13,15 can also be used and a large number of other shapes of the section, regular or irregular, are also conceivable.
    The ferrule 7 can also be detached from the axis 3 by moving the latter in translation towards the first sub-area and 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 FIG. 1.
    In this variant, the receiving area 11 and the section 5 are shaped so that the axis 3 can be inserted therein in said axial direction Z and is subsequently clamped against the positioning surface 13 by the holding surfaces 15 by pivoting the axis 3 relative to the ferrule 7.
    In this variant, 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 so to partially surround the zone 11. In order to give them increased elasticity, each of the arms 17 is folded inwards and the folded parts carry the retaining surfaces 15.
    The receiving area 11 and the shape of the section 5 are complementary and have a relationship such that, in a first angular orientation relating to these two elements, the axis 3 can be inserted in the area 11 in said axial direction Z. This relation is illustrated in fig. 4a in solid lines and shows that there is sufficient clearance so that the section 5 does not come into contact with the ferrule 7 when it is inserted into said zone in a direction parallel to the axis 5. Alternatively, a slight contact between axis 5 and surfaces 11 and 13 may be allowed.
    Subsequently, by pivoting the axis 3 relative to the ferrule 7, the periphery of the section 5 abuts against the holding surfaces 15, which are moved to ('against the restoring force provided by the elastic arms 17. The angular relationship between these components at this time is illustrated in Fig. 4a in dotted lines, in which a corner of the section 5 is in contact with the positioning surface 13. In order to limit the stresses undergone by the elastic arms 17 , the positioning surface 13 may include a notch 23 which allows a corner of the section 5 to enter there during the
    CH 714 001 A1 rotation of the axis 3 relative to the ferrule 7. The movement of the holding surfaces 15 and also the stresses generated in the arms 17, can thus be limited.
    By pivoting the axis 3 even further relative to the shell 7, the axis 3 adopts a stable position in a second relative angular orientation illustrated in solid lines in FIG. 4b, this angular orientation being distinct from the first angular orientation mentioned above. In 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 as well as of the section 5 is illustrated in dotted lines), and tighten the section 5 against the positioning surface 13.
    In the illustrated embodiment, the section has a shape comprising a flat 19 which is positioned against the positioning surface 13 (which is also flat except for the notch 23) in the service position as well as two rounded corners 25 arranged to be in contact with the retaining surfaces 15. The flat 19 is linked to the rounded corners 25 by planar surfaces.
    However, it goes without saying that a large number of forms of positioning surfaces 13, of holding surfaces 15 and of section 5 fulfill the desired aim, the embodiment illustrated is therefore not limiting. One could imagine that the section 5 could have angular, curved, polygonal, oval, irregular shapes and any combination of these. The holding surfaces 15 can take the form of long necklaces, fingers, tongues or any other suitable shape. As for the elastic restoring force for these surfaces, it can be provided by elastic elements of any kind which are in one piece with said surfaces 15 or which are constituted by additional elements brought to the ferrule 7. Furthermore, the positioning surface 13 can be curved, angular, irregular or any other suitable shape. Indeed, any combination of shapes of the surfaces 13, 15 and of the section 5 which allows a stable tight angular position as well as an angular position allowing the axis 5 to enter the receiving zone 11, substantially without displacement of the surfaces of support 15, suitable for implementing the invention. FIG. 5 also illustrates a variant of a regulating member 1 according to the invention, which operates in a manner similar to that of FIGS. 4a and 4b.
    This embodiment differs from that of FIGS. 4a and 4b in that only a first of the holding surfaces 15a, 15b is movable 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 d 'an elastic arm 17a which extends from the root 9a of the spring 9 and which partially surrounds 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 was launched from the root 9a in the other direction. The end of this elastic arm 17a therefore forms a finger which carries the first holding surface 15a, the latter pressing against the section 5 in order to clamp the latter against the positioning surface 13 as well as against the second holding surface 15b. Indeed, 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 to the direction of the force provided by the only elastic arm 17a and therefore requires guiding the section 5 via the second holding surface to effect the tightening.
    Again, the reception area 11 is defined at least partially by the surfaces 13, 15a and 15b, the section 5 having a section of complementary shape allowing the insertion of the axis 3 in said area 11 in the direction axial Z when the axis 3 and the ferrule 7 are in a first relative angular orientation (illustrated in dotted lines). By pivoting the axis in the direction of the arrow, the rounded corner 25 of the section 5 lifts the first holding surface 15a and flexes the elastic arm 17a. When the axis 3 and the ferrule 7 have reached their second relative angular orientation (illustrated in solid lines), the elastic arm 17a remains bent and clamps the section against the positioning surface 13 as well as against the second holding surface 15b. By returning the ferrule 7 and the axis 3 to their first angular orientation, these components are thus separated from one another and the axis can be removed in the axial direction Z.
    In the variants illustrated in FIGS. 4a, 4b and 5, the angle between the first angular orientation and the second angular orientation is 60 °, but any suitable angle can be used.
    In the embodiments of FIGS. 2 to 5, if the section 5 is machined in the body of the axis 3, the edges of the section 5 (considered along the axis 3) can constitute shoulders which serve as stops to prevent the displacement of the ferrule 7 along the axis when the latter is tight. In such a case, the section 5 does not extend all along the axis 3 but occupies a length of between 100% and 120%, preferably between 101 and 115% of the thickness of the ferrule 7. Alternatively, larger size stops can be used (see above).
    [0057] FIG. 6 illustrates more fully a part of a regulating member 1 according to the invention, the flywheel (such as a pendulum) not being illustrated so as not to overload the drawing.
    On one side of the axis 3 is mounted the spiral spring 9 as shown in Figs. 4a and 4b. It goes without saying that the use of any variant of ferrule 7 described above is also possible.
    In order to guarantee the correct positioning and axial retention of the ferrule 7 on the axis 3, 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 ferrule 7 are in their second relative angular orientation, and to be able to pass through said zone 11 when the axis 3 and the ferrule 7 are located in their first orientation
    CH 714 001 A1 relative angular. The same applies to the embodiments of FIGS. 1 to 3, in which the locking element 29 forms an axial stop when the axis 3 and the ferrule 7 are in a first position 11 a and in order to be able to pass through the reception zone 11 when the axis 3 and the ferrule 7 are in a second position 11b.
    To this end, the locking element 29 illustrated has a triangular shape with truncated vertices 31. These vertices 31 constitute lugs which can pass through said zone 11 in said first angular orientation, and which 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 as well as the shoulder 27 thus block the component 3 axially on the axis 5. It goes without saying that other forms of locking element 29 are possible, which include at least one lug 31 or projection projecting arranged to form an axial stop when the axis 3 and the ferrule 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 31 (or any other suitable non-circular shape provided on an additional section of the axis) which is used 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 FIG. 2, the flat 31 indexing the axis relative to the plate 33 by its interaction with the positioning surfaces 13. However, the plate 33 can also be fixed on the axis in the same way as the ferrule in any other variant of the invention described above.
    The plate 33 comprises a pin 35 whose sides 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 area of reception 11 including the sub-areas 11a and 11b have a greater height than that of the dowel 5, which is used to position the plate 33 relative to an additional shoulder 36, and to give the ends increased rigidity.
    In the illustrated embodiments, the section 5 always has at least one line of symmetry, but it is also possible that its shape is irregular. Furthermore, the elastic arms 17, 17a, 17b of the variants of FIGS. 1 - 4b and 6, which have been shown in symmetrical shapes, may also be different from each other and asymmetrical.
    Indeed, it is not important that the forces exerted by the holding surfaces are identical or are exerted symmetrically.
    Even if the principle of the invention is particularly advantageous when component 2 is made of brittle material as mentioned in the preamble, it also applies to components 3 of metal or metallic composite or of conventional polymer.
    Although the invention has been particularly shown and described with reference to particular embodiments, other variants are possible without departing from the scope of the invention as defined in the claims.
