Definitions

  • the invention relates to a spiral spring for a watch movement.
  • the invention also relates to an assembly, in particular a watch movement, comprising such a spiral spring.
  • the invention finally relates to a timepiece comprising such a spiral spring or such an assembly.
  • EP2437126 discloses different spiral springs which are each provided with a connecting member.
  • the connecting member can have either the shape of a portion of a circle, or even a circle, or a rectilinear shape.
  • This connecting member is in the form of a single element, which is not intended to be actuated by frolic adjustment elements.
  • Requirement JP2016173241 relates to a device for attaching a spiral spring, also serving as a shock-absorbing device intended to protect the turns from shocks.
  • the spiral spring comprises a connecting member consisting of two portions having different resilience, these portions being able to be delimited by the positioning of the outer end of the turns of the spiral spring.
  • This connecting member is in the form of a single element, which is not intended to be actuated by frolic adjustment elements.
  • Requirement EP3032354 relates to a device for rotating a spiral spring relative to a fixing support, which is shaped so that the alignment operation can be carried out directly by the rotation of the spiral, and not by the rotation of the fixing support.
  • the spiral spring includes a connecting member.
  • the screw fixing of a balance bridge to the plate induces the attachment of the outer end of the spiral spring to the movement frame, in particular by the fact that the connecting member is pinched between the plate and the bridge of pendulum.
  • this connecting member is not intended to be actuated by frolic adjustment elements.
  • the aim of the invention is to provide a spiral spring making it possible to improve the spiral springs known from the prior art.
  • the invention proposes a spiral spring specially shaped to be actuated by frolic adjustment elements.
  • this spiral spring conformation avoids any risk of deformation of the spring leaf when handling axial movement adjustment elements.
  • a spiral spring according to the invention is defined by claim 1.
  • Embodiments of a spiral spring according to the invention are defined by dependent claims 2 to 6.
  • Embodiments of an assembly according to the invention are defined by dependent claims 8 to 14.
  • a timepiece according to the invention is defined by claim 15.
  • a first embodiment of a timepiece 400 is described below in detail with reference to the figures 1 to 5 .
  • the timepiece 400 is for example a watch, in particular a wristwatch.
  • the timepiece 400 comprises a watch assembly or movement 300 intended to be mounted in a timepiece case or box in order to protect it from the external environment.
  • the watch movement 300 can be a mechanical movement, in particular an automatic movement, or even a hybrid movement.
  • the first blank 5 and the second blank 6 form part of a frame of the assembly or movement.
  • the frame can also include a bridge 8 for protecting the balance 9.
  • the spiral spring 1 is configured and/or arranged so that a first displacement (axial, parallel to the axis A1 or perpendicular to the plane P1 or the plane P2) of a first amplitude of the first fixing element 13a relative to the second fixing element 13b does not cause movement of the second arm 122, in particular of the first junction zone 122a, or causes a second movement of a second amplitude of the second arm 122, in particular of the first junction zone 122a, relative to the second fixing element 13b, the second amplitude being less than 0.15 times or 0.1 times or 0.05 times the first amplitude.
  • the second arm 122 is not movable or very little movable and connects the external end of the blade 11 of said spiral spring to a second portion 121b of the first arm 121.
  • the spiral spring 1 is intended to be integrated within the assembly device 200.
  • This assembly device is intended to embed at least the second arm 122, in particular downstream of a junction zone 123 of the second arm 122 and of the second portion 121b of the first arm 121.
  • the axial movement adjustment elements mentioned above and capable of acting on the first portion 121a of the first arm 121 form part of the assembly device 200.
  • the elements 11 and 121, 122 of the spiral spring 1 extend respectively along the planes P1 and P2 which are preferably parallel or substantially parallel to the plane P within which the movement 300 extends.
  • the vertical and oriented directions, referenced z1 for a first direction and z2 for a second direction (opposite to the first direction), are perpendicular to the planes P, P1, and P2.
  • Such an assembly device 200 has the advantage of authorizing the movement of the first portion 121a of the first arm 121 in the vertical or substantially vertical direction, and this without causing the movement and/or deformation of the second arm 122, and therefore a fortiori of the blade 11.
  • the chronometric performances are thus independent of the swing setting of the oscillator.
  • the connecting member 12 is positioned and fixed in the plane P relative to the first blank 5, for example a balance bridge 5, and to the second blank 6, for example a plate 6 of movement 300.
  • the connecting member 12 is positioned and fixed in the plane P between the first and second blanks 5 and 6.
  • the balance-spring assembly 100 in particular the axis 10 of the balance-spring 100, is here pivoted by respective bearings 50 and 60 of the balance bridge 5 and the plate 6.
  • the axial movement adjustment elements are provided for moving the bearing 50 relative to the bearing 60 in the vertical direction by the movement of the first blank 5 relative to the second blank 6, in particular the movement in the vertical direction or a direction substantially parallel to this direction of a first portion 5a of a balance bridge relative to a second portion 5b of a fixed balance bridge relative to the plate 6.
  • the first and second portions 5a, 5b can for example constitute the ends longitudinal 5a, 5b of a balance bridge 5, as shown in the figure 1 .
  • the balance bridge 5 is through as illustrated in the figure 1 , that is to say that it is fixed to the second blank 6 on either side of the balance 9.
  • the axes of the fixings of the balance bridge 5 are arranged at an angle of approximately 180° relative to the axis A1 of the balance-spring assembly 100, in particular the axis 10. This angle can for example be between 130° and 180°. On the figure 1 , the angle is approximately 165°.
  • the portions 121a and 121b each comprise, at one of their respective ends, a fixing and positioning element 13a, 13b of the spiral spring facing the first blank 5 and the second blank 6, which is detailed below -After.
  • the second arm 122 has a rectilinear or substantially rectilinear shape which is oriented radially or substantially radially relative to the axis A1.
  • a first end 122a of the arm 122 adjoins the blade 11 of the spiral spring and constitutes a junction zone 122a of the connecting member 12 to the blade 11, while a second end 122b of the arm 122 adjoins the second portion 121b of the first arm 121 and constitutes a junction zone 123 of the second arm 122 to the first arm 121.
  • the junction zone 123 of the second arm 122 to the first arm 121 is located at the level of of the fixing and positioning element 13b. Consequently, a slot 124, oriented radially or substantially radially relative to the axis A1, can separate the arms 121 and 122, in particular the second portion 121b and the second arm 122.
  • the fixing and positioning elements 13a, 13b here take the form of openings, in particular through openings, which are intended to cooperate respectively with positioning elements 7a, 7b also provided to allow the positioning (and fixing) of the first blank 5 relative to the second blank 6 in plane P.
  • Each positioning element 7a, 7b is presented here in the form of a screw foot driven respectively into an opening 61a, 61b of the second blank 6, in particular at the level of a respective driving portion 74a, 74b of each element positioning 7a, 7b.
  • each screw foot 7a, 7b is designed to be housed within the respective openings 13a, 13b.
  • each screw foot 7a, 7b more particularly comprises a guide portion 71a, 71b which is provided to precisely position the outer end of the spiral spring 1, in particular the connecting member 12, vis-à-vis balance bridge screw 5 and plate 6.
  • the geometry of the guide portions 71a, 71b corresponds to the geometry of the openings 13a, 13b, up to the assembly clearance.
  • the guide portions 71a, 71b are cylindrical or at least partially cylindrical.
  • the opening 13b is circular, while the opening 13a is oblong, in particular in a direction oriented towards the center of the opening 13b, in order to avoid any risk of hyperstatism during the assembly of the balance-spring assembly 100 and/or to allow the opening 13a to move in a substantially vertical direction facing the screw foot 7a.
  • the first blank 5 also comprises through openings 51a, 51b provided to accommodate the screw feet 7a, 7b, which are located respectively at the level of the portions 5a, 5b of the first blank 5.
  • Each screw foot 7a, 7b more particularly comprises a guide portion 72a, 72b which is intended to precisely position the first blank 5 in the plane P via the respective openings 51a, 51b.
  • the opening 51a can also have an oblong shape, in particular oriented towards the center of the opening 51b, in order to avoid any risk of hyperstatism during the assembly of the balance-spring assembly 100 and/or to allow the movement of the portion 5a in a substantially vertical direction facing the screw foot 7a.
  • the assembly device 200 can optionally also include a bridge 8 for protecting the balance wheel 9.
  • This bridge is arranged (at least partially) on the plate 6.
  • this is also positioned relative to the plate 6 in the plane P also via screw feet 7a, 7b.
  • the bridge 8 includes through openings 81a, 81b intended to accommodate the screw feet 7a, 7b at the level of guide portions 73a, 73b of the balancer protection bridge 8.
  • the opening 81a may also have an oblong shape, in particular oriented towards the center of the opening 81b, in order to avoid any risk of hyperstatism during the assembly of the balance-spring assembly 100 and/or to allow moving the opening 81a in a substantially vertical direction facing the screw base 7a.
  • the assembly may include a third blank 8, the third blank being for example a protective bridge 8 and/or the third blank being for example interposed or arranged between the first and second blanks 5, 6.
  • the connecting member 12 of the spiral spring is positioned between the first blank 5, typically the balance bridge 5, and the second blank 6, typically, the plate 6.
  • the connecting member 12 of the spiral spring can be positioned between the balance bridge 5 and the balance protection bridge 8.
  • the upper surface 112 of the spiral spring 1, more precisely of the connecting member 12 is in contact against a lower support surface 52 of the balance bridge 5, and the lower surface 111 of the spiral spring 1, more precisely of the connecting member 12, is in support of the against an upper bearing surface 82 of the balancer protection bridge 8.
  • the spiral spring 1, in particular the connecting member 12 is thus pinched between the first blank 5 and the second blank 6.
  • the second junction zone 123 of the first arm 121 and the second arm 122 is maintained, in particular kept interposed or pinched, between the first blank 5 and the second blank 6.
  • the fixing of the balance-spring assembly 100 on the movement 300, in particular of the sprung spring 1, is carried out during the fixing of the balance bridge 5 on the plate 6 by means of screws 91a, 91b provided to be screw into respective tapped holes 75a, 75b of the screw feet 7a, 7b.
  • the spiral spring 1, in particular the connecting member 12, is thus positioned and pinched between the first blank 5 and the second blank 6.
  • These guide portions are preferably cylindrical or at least partially cylindrical.
  • the diameter of the second guide portion 72a, 72b is less than that of the first guide portion 71a, 71b.
  • the diameter of the first guide portion 71a, 71b is less than that of the third guide portion 73a, 73b.
  • An upper surface of the nut 92 is in contact with a lower surface 83 of the balance protection bridge 8, so that the portion 121a of the arm 121 of the connecting member 12 is positioned and fixed in the plane P or substantially in the plane P between the balance bridge 5 and the plate 6 via the balance protection bridge 8 and the nut 92.
  • the portion 121a of the arm 121 is pinched between the balance bridge 5 and the balance protection bridge 8, the latter being arranged directly on the nut 92.
  • the nut 92 also preferably comprises a toothed portion 922 which is designed to cooperate by meshing with a toothed portion 932 of an adjustment nut 93.
  • This nut comprises a conformation 931, in particular a screw head 931, which is capable of to be rotated by a watchmaking tool, such as a screwdriver.
  • a rotation of the nut 93 thus induces a rotation of the nut 92 around the screw foot 7a, as well as a translation of said nut 92 in the vertical direction, which makes it possible to generate a vertical or substantially vertical movement of the first portion 5a of balance bridge 5, via the balance protection bridge 8 and the portion 121a of the arm 121 of the connecting member 12, more particularly via the first fixing element 13a.
  • the fixing element 13a preferably cooperates with the positioning element 7a and/or rests on the nut 92.
  • the second arm 122 of the connecting member 12 is pinched between the first blank 5, in particular the balance bridge 5, and the second blank 6, in particular the plate 6. More precisely, the second arm 122 of the connecting member 12 is pinched between the second portion 5b of the balance bridge 5, and the balance protection bridge 8.
  • the screw foot 7b does not constitute an axial swing adjustment element.
  • the balance bridge 5, the arm 122 and the balance protection bridge 8 are therefore fixed relative to the plate 6, in particular in the vertical direction.
  • the blanks 5, 6, and 8 define an embedding connection of the second arm 122, which is fixed relative to the frame of the movement 300. This embedding connection is more particularly defined at the level of the support zone delimited schematically by the curve E in mixed line on the figure 5 .
  • the second portion 121b of the arm 121 is also pinched between the first blank 5, in particular the balance bridge 5, and the second blank 6, in particular the plate 6. More precisely, the second portion 121b of the arm 121 is pinched between the balance bridge 5, in particular the second portion 5b, and the protection bridge of balance 8.
  • the blanks 5, 6, and 8 also define an embedding connection of the second portion 121b of the arm 121, which is fixed relative to the frame of the movement 300. This embedding connection is more particularly defined at the level of the zone support delimited schematically by the curve E in phantom on the figure 5 .
  • the arm 122 and the second portion 121b of the arm 121 are thus fixed relative to the movement frame. They are embedded by the blanks 5, 6, and 8 at the level of the support zone delimited schematically by the curve E. In particular, the arm 122 and the second portion 121b of the arm 121 are embedded upstream of the junction zone 123 which connects the arm 122 to the second portion 121b of the arm 121. Thus, the arm 122 is not impacted by a possible movement and/or deformation of the arm 121, in particular of the second portion 121b of the arm 121.
  • upstream and downstream are assessed with regard to a vector V ( Figures 1 , 5 ), which passes through the respective centers of the screw feet 7a, 7b, and therefore those of the openings 13a, 13b, and which is oriented from the screw foot 7a towards the screw foot 7b, and therefore from the opening 13a towards the opening 13b.
  • the vector V moves away in particular from the axis A1 towards the screw foot 7b or the opening 13b.
  • Vector V points downstream.
  • the junction zone 123 is located at the level of the fixing element 13b of the connecting member 12, which constitutes one end of the second portion 121b of the arm 121 and one end 122b of the second arm 122.
  • This junction zone 123 at least partially comprises the material which adjoins the longitudinal end 124a of the slot 124.
  • the arm 122 and the second portion 121b of the arm 121 are embedded upstream of the longitudinal end 124a of the slot 124 ( Figure 5 ).
  • a movement in the vertical direction of the first portion 121a of the first arm 121 therefore has no effect on the second arm 122, and therefore a fortiori on the blade 11 of the spiral spring. Indeed, the blade 11 is connected to the rest of the spiral spring 1 via the second arm 122. Such a design therefore makes it possible to preserve the geometric integrity of the blade 11 of the spiral spring 1 when adjusting the axial frolic of oscillator 100.
  • a second embodiment of a timepiece 400' is described below in detail with reference to the Figure 6 .
  • the timepiece 400' is for example a watch, in particular a wristwatch.
  • the timepiece 400' comprises an assembly or a watch movement 300' intended to be mounted in a case or a timepiece box to protect it from the external environment.
  • the 300' watch movement can be a mechanical movement, in particular an automatic movement, or even a hybrid movement.
  • references of the elements are deduced from the references of the elements of the first embodiment which provide an identical or similar function by adding a "'".
  • the second embodiment only differs from the first embodiment by the arrangement and/or configuration of the first arm 121' and second arm 122' of the connecting member 12'.
  • the junction zone 123' of the second arm 122' to the first arm 121' is located at a location different from the end of the second portion 121b' of the arm 121' and the end of the second arm 122'.
  • the Figure 6 schematically illustrates an alternative assembly device 200' using a spiral spring 1' comprising a junction zone 123' of the second arm 122' to the first arm 121' which is located substantially halfway between a fixing element 13b ' and the junction 122a' of the connecting member 12' to the blade 11'.
  • a rigid holding plate 99' fixed to the frame of the timepiece can come to bear against the second arm 122', for example at the level of the support zone delimited by the curve E '. This plate can contribute to embedding the second arm 122', and more generally the connecting member 12', into the frame.
  • junction zone 123' is for example interposed between the holding plate 99' and a fixing element 13b' of the spiral spring 1' which constitutes an end 121b' of the first arm 121', opposite another end of the first arm 121 which includes another fixing element.
  • the ratio of the length of the first arm to the length of the second arm is advantageously between 2 and 10 or between 3 and 8.
  • the spiral spring is in one piece.
  • the blade 11, the connecting member 12 and the ferrule 14 are manufactured in one piece.
  • the spiral spring can for example be attached to the blade 11.
  • arm is meant, throughout this application, a conformation having a length, a width and a thickness, the length being at least twice greater than the largest of the other dimensions (width and thickness).
  • the length is possibly measured according to a non-rectilinear curve if the conformation extends according to this non-rectilinear curve.
  • the solutions described above are based on a spiral spring equipped with a connecting member which has the particularity of comprising two distinct arms each having a rigidity significantly greater than that of the blade of the spiral spring, a first portion of a first arm being capable of being moved in a vertical or substantially vertical direction, and a second non-movable arm connecting the external end of the blade of said spiral spring to a second portion of the first arm.
  • a spiral spring is advantageously designed to be integrated within a device for assembling an oscillator which is designed to embed at least the second arm, in particular upstream of the junction zone of the second arm and the second portion of the first arm, and which comprises axial movement adjustment elements capable of acting on the first portion of the first arm.
