Description

Technical field of the invention

[0001] The invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking.

[0002] The invention relates more specifically to an assembly of two watch components for a watch movement. Technological background

[0003] In most mechanical watches, the components are assembled together on a plate by known standard means, such as driving in, screwing in, casing up, or more rarely gluing, bonding or soldering.

[0004] The components are generally mounted in the movement in a stack of successive planes substantially parallel to the plate. The components are for example gear wheels, bridges, etc.

[0005] Some components must be mounted perpendicular to the plane of the turntable, such as the rotation shafts, for example for the gear wheels or the balance wheel. However, because rotation shafts are small, they are easy to assemble.

[0006] However, some larger components are more complex to assemble into the movement, especially if they have to be assembled orthogonally to the plate.

[0007] Additionally, they may need to interact with other movement components, such as by interlocking or meshing, making them difficult to assemble.

[0008] Another problem with assembling watch components is the possible presence of play between the two components once assembled. Summary of the invention

[0009] The aim of the present invention is to overcome all or part of the drawbacks mentioned above by proposing means for assembling a watch component in a watch movement, which avoids the aforementioned problems.

[0010] To this end, the invention relates to an assembly of two timepiece components for a timepiece movement, the assembly comprising a first timepiece component, for example a plate extending along a first plane, and a second timepiece component, for example an actuator of an actuation system, the assembly comprising means for assembling the first timepiece component on the second timepiece component.

[0011] The invention is remarkable in that the assembly means comprise means for positioning the second component on the first component in a plane substantially parallel to the first component, and means for pressing on the second component to block the second component on the first component in a direction substantially orthogonal to the first component.

[0012] Thanks to the invention, an efficient and simplified assembly of the two watch components is obtained, because it is sufficient to position the second component on the first component and hold it laterally by the positioning means, then to arrange support means on the second component to block it and assemble it on the first component.

[0013] Indeed, these assembly means are simple to implement and effective, because the positioning means place the second component in a plane substantially parallel to the plane of the first component, and the support means retain the second component, in a second direction perpendicular to the previous plane.

[0014] In addition, such an assembly makes it easy to assemble a watch component perpendicular to the plate.

[0015] According to a particular embodiment of the invention, the second component extends in a plane substantially perpendicular to the first component.

[0016] According to a particular embodiment of the invention, the positioning means comprise at least one first lug, preferably two lugs, arranged on the second component, and at least one hole, preferably two holes, arranged in the first component, so that each lug is introduced into a hole to assemble the two components.

[0017] According to a particular embodiment of the invention at least one lug can be snapped into a hole.

[0018] According to a particular embodiment of the invention, the support means comprise an assembly body arranged on the first component, and the second component comprises a support face, on which the assembly body presses to block the second component.

[0019] According to a particular embodiment of the invention, the assembly body comprises a rigid tab for pressing on the first component.

[0020] According to a particular embodiment of the invention, the second component comprises an opening allowing the passage of the rigid tab.

[0021] According to a particular embodiment of the invention, the assembly means comprise a screw and the assembly body comprises a passage for assembling the assembly body on the first component, the first component being provided with a tapped hole for the screw.

[0022] According to a particular embodiment of the invention, the second component comprises a fixed part intended to be mounted on the first component, and a part movable relative to the first component.

[0023] According to a particular embodiment of the invention, the fixed part comprises the lug(s).

[0024] According to a particular embodiment of the invention, the opening is arranged between the fixed part and the movable part.

[0025] According to a particular embodiment of the invention, the assembly body presses on the fixed part.

[0026] The invention also relates to a clockwork movement comprising such a clockwork assembly.

[0027] The invention also relates to a timepiece, for example a watch, comprising such a timepiece movement. Brief description of the figures

Detailed description of the invention

[0029] In the following description, the subject of the invention, which is a timepiece assembly, is provided with means for assembling two timepiece components, the first component of which is the plate of a timepiece movement, and the second component of which is an actuator of adjustment means of a regulating organ. However, such an assembly could relate to other components of a timepiece movement, and it is in no way limited to these components or to other components of a regulating organ.

[0030] There Figure 1 shows a schematic representation of an embodiment of a part of a clockwork movement comprising a plate provided with a housing and a regulating member 1. Such a movement is for example arranged in a timepiece, such as a watch.

[0031] The regulating organ 1 comprises an inertial mass, here an annular balance 23, a balance spring 25 as an elastic return element of the inertial mass configured to make it oscillate, a balance shaft, and a balance bridge, not shown in the figure. The elements are superimposed from bottom to top in the following order: the first timepiece component 22, the balance 23, and the balance spring 25.

[0032] The balance shaft passes through the center of the balance wheel and the balance spring 25. The balance shaft is held by two shock-absorbing bearings 28 arranged at both ends of the balance shaft. A first bearing is arranged below, in the plate 22, and the second bearing 28 is arranged in the balance bridge. The balance bridge is provided with a through hole in which the second bearing 28 is held.

[0033] Represented on the Figure 2, the spiral spring 25 preferably extends substantially in a plane. The spiral spring 25 comprises a flexible ribbon 2 wound on itself in several turns, the ribbon 2 having a predefined stiffness. The internal end 9 of the ribbon 2 comes from the same material or is assembled to a rigid support 3, generally called a collet. The rigid support 3 has a substantially triangular shape, and is threaded around the balance shaft.

[0034] The spiral spring 25 further comprises means for adjusting its stiffness. For example, the adjustment means can be actuated by a user when the regulating member is mounted in the watch movement.

[0035] The adjustment means comprise a flexible element 5 arranged in series with the ribbon 2, that is to say following the ribbon, preferably in its extension, the flexible element 5 connecting an external end 4 of said ribbon 2 to a rigid support 53. The flexible element 5 is integral with the external end 4 of the ribbon 2. The flexible element 5 is an element different from the ribbon 2.

[0036] The flexible element 5 adds additional stiffness following that of the strip 2. The flexible element 5 preferably has a stiffness greater than that of the strip 2. The flexible element 5 is here arranged in the extension of the strip 2. Preferably, the adjustment means and the strip 2 are in one piece, or even formed from the same material, for example silicon.

[0037] In this embodiment of the spiral spring, the flexible element 5 comprises two flexible parts 15, 16 each connecting the ribbon 2 to a fixed support 53.

[0038] The two flexible parts 15, 16 are arranged, relative to each other, by axial symmetry along an axis A of the spiral spring 25. In other words, the two flexible parts 15, 16 are positioned so as to be symmetrical relative to said axis A.

[0039] On the one hand, the axis A passes substantially through the center O of the spiral spring, and on the other hand, the axis A passes, preferably, through the external end 4 of the ribbon 2.

[0040] Thus, the two flexible parts 15, 16 are arranged at the periphery of the spiral spring, so that the two flexible parts 15, 16 are arranged at the same distance from the center O of the spiral spring 25.

[0041] The two flexible parts 15, 16 are preferably arranged relative to each other in a "mirror" type position relative to the axis A. For this purpose, the two flexible parts 15, 16 are preferably substantially identical.

[0042] The flexible parts 15, 16 each comprise a curved flexible blade 55, preferably forming a semicircle, and extending from the end of the fixed support 53. Each curved flexible blade 55 is further connected to the external end 4 of the ribbon 2 by a flexible blade 7.

[0043] The fixed support 53 has the shape of a trapezoid closed by a flexible blade 7.

[0044] The spiral spring adjustment means 25 further comprise pre-stressing means 6 for applying a variable force or torque to the flexible element 5. Thus, the stiffness of the spiral spring can be adjusted. The torque or force is continuously adjustable by the pre-stressing means 6. In other words, the torque or force is not restricted to point values. Thus, the stiffness of the flexible element 5 can be adjusted with great precision.

[0045] Preferably, the prestressing means 6 apply a substantially identical force or torque to each flexible part 15, 16. The directions of the forces are preferably substantially symmetrical.

[0046] The prestressing means 6 further comprise two levers 14, 26 each connecting a curved blade 55 to the same mobile body 19 arranged on the other side of the spiral spring 25 relative to the fixed support 53.

[0047] The movable body 19 has, for example, a U shape, allowing it to be engaged with an actuator, for example provided with a notch or a finger inserted into the U, because it is arranged tangentially to the levers 14, 26.

[0048] The variable force or torque is applied to the movable body 19. The variable force or torque is at least partly transmitted to the curved blades 55 of the flexible parts 15, 16 of the flexible element 5, via the levers 14, 26.

[0049] To be able to apply the variable force or torque to the spiral spring 25, the regulating member comprises a particular actuation system 20.

[0050] In this embodiment, the regulating member 1 comprises a stud holder 31 provided with a suspended stud 34. The stud holder 31 is mechanically linked to the flexible element 5, but it does not block the ribbon 2. The stud holder 31 surrounds the second bearing 28. For this, the stud holder 31 comprises a central ring arranged around the second bearing 28, and which rests on the balance bridge (not shown).

[0051] The stud 34 cooperates with the rigid support 55. Thus, the prestressing means 6 and the flexible element 5 are supported by the stud holder 31 from which they are suspended.

[0052] Furthermore, the stud 34 is rigidly connected to the rigid support 55. In other words, the stud 34 is integral with the rigid support 55. The assembly of the stud 34 and the spiral spring 25 is for example carried out by gluing, brazing, welding, by deformation of metallic glass, or by mechanical fixing.

[0053] The stud 34 is movable relative to the first timepiece component 22. To this end, the stud holder 31 is movable in rotation around the second bearing 28 relative to the first timepiece component 22. The stud holder 31 can for example be moved over an angular range of 20°, or even 10°.

[0054] The movement of the stud 34 relative to the first clockwork component 22 makes it possible to adjust the reference of the regulating organ 1.

[0055] The actuation system 20 further comprises a second timepiece component 30, which is an actuator configured to actuate the mobile body 19. The second timepiece component 30 is mechanically connected to the prestressing means 6, the second timepiece component 30 being configured to perform at least in part a substantially linear movement, preferably rectilinear in a plane substantially perpendicular to the plate, to actuate the prestressing means 6.

[0056] In other words, at least a portion of the second timepiece component 30 moves substantially along a straight line, unlike, for example, the stud holder 31 which undergoes rotation by turning around an axis, in a plane substantially parallel to the plate. Thus, at least a portion of the second timepiece component 30 moves closer to or further away from the spiral spring 25 in a direction oriented substantially towards the spiral spring.

[0057] Preferably, the direction of movement of the second timepiece component 30 is substantially radial relative to the balance 23 and the balance spring 25. Thus, the straight line along which the second timepiece component 30 moves is directed towards the center of the balance 23 and the balance spring 25. In addition, this makes the adjustment of the rate independent of the adjustment of the reference mark. Indeed, the movement of the stud 34 relative to the first timepiece component 22 makes it possible to adjust the reference mark of the regulating member 1.

[0058] The second timepiece component 30 is eccentric relative to the regulating member, i.e. mounted at a distance from the center of the regulating member 1, and is only connected to the movable body 19 of the adjustment means. Thus, the second timepiece component 30 is not mounted directly on the regulating member 1, like a stud holder on a bearing 28 of the regulating member 1 for example.

[0059] Thus, the clockwork movement comprises an assembly 10 comprising the first clockwork component 22, here the plate, and the second clockwork component 30, here an actuator of the adjustment means.

[0060] In this embodiment, the first timepiece component 22 is the plate of the timepiece movement, and the second timepiece component 30 is an actuator. The second timepiece component 30 is mounted on the first timepiece component 22. The second timepiece component 30 is mounted perpendicular to the first timepiece component 22.

[0061] On the Figure 3, the second timepiece component 30 comprises in particular a fixed part 33 mounted on the first timepiece component 22, a movable part 37 relative to the first timepiece component 22 and connected to the levers 14, 26, as well as a spring part 35, formed of a flexible guide, joining the movable part 37 to the fixed part 33. The fixed part 33 and the movable part 37 are preferably rigid. The fixed part 33, the spring part 35 and the movable part 37 are preferably arranged in the same plane. Thus, the second timepiece component 30 is generally flat, and extends substantially in a plane.

[0062] To actuate the moving body 19, the second clockwork component 30 comprises a hook 39 engaged with the U of the moving body 19. The hook 39 is closed, but it could also be partly open.

[0063] A displacement, radial relative to the spiral spring 25, of the movable part 37 of the second timepiece component 30 pulls or pushes the movable body 19, radially relative to the spiral spring 25, and thus actuates the levers 14, 26. Thus, the stiffness of the flexible element 5 is modified, because the displacement of the levers 14, 26, integral with the movable body 18, exerts a more or less significant force or torque on the flexible element 5, so that the stiffness of the flexible element 5 varies, and consequently the stiffness of the spiral spring 25 as a whole. The actuation system 20 thus makes it possible to adjust the rate of the regulating member 1.

[0064] The fixed part 33 here has a substantially elongated shape, and comprises a bar 63 intended to be mounted on the first component 22.

[0065] As shown in the figures, the second timepiece component 30 is mounted on the first timepiece component 22, so as to be substantially perpendicular to the first timepiece component 22.

[0066] The spring part 35 is arranged under the fixed part 33, so that it extends below the level of the first clockwork component 22.

[0067] The spring part 35 here comprises two translation tables 51, 52 with flexible blades arranged in series, one after the other. They are defined as being in series, because the movements of each translation table add up at least in part.

[0068] Each translation table 51, 52 comprises a pair of substantially parallel flexible blades 61, 62 and a rigid section 56, 57, on which the pair of flexible blades 61, 62 is mounted.

[0069] The first translation table 51 is arranged on the fixed part 33 and comprises a first rigid section 56 extended to associate therewith a second translation table 52 arranged head to tail with respect to the first translation table 51, that is to say in the opposite direction. Thus, the second pair of flexible blades 62 is substantially parallel to the first pair of flexible blades 61.

[0070] The second rigid section 57 is substantially parallel to the first rigid section 56, but is offset.

[0071] Such an arrangement of translation tables 51, 52 makes it possible to obtain a movement of the mobile part 37, which is substantially linear, preferably rectilinear, while maintaining a second compact clockwork component 30.

[0072] Two translation tables arranged head to tail allow mutual compensation of the vertical deviation of the hook 39 generated by each. Thus, the hook 39 remains substantially at the same height when it moves.

[0073] The movable part 37 extends from the second section 57. The movable part 37 is preferably rigid. The movable part 37 here has the shape of an elbow formed of a first segment 66 arranged perpendicular to the second section 57 and a second segment 67 forming a right angle with the first segment 66.

[0074] The hook 39 of the second timepiece component 30 is arranged at the end of the branch of the second segment 67. At the free end of the first segment 66, a bulge 68 serves as a support to be able to move the movable part 37.

[0075] By pressing more or less hard on the bulge 68, the movable part 37 moves in a manner substantially parallel to the fixed part 33, thanks to the deformation of the translation tables 51, 52 of the spring part 35.

[0076] Thus, the hook 39 pulls more or less strongly on the levers 14, 26, via the movable body 19, to actuate the means for adjusting the stiffness of the flexible element 5.

[0077] The direction of movement of the moving part 39 of the second timepiece component 30 and of the moving body 19 is substantially orthogonal to the direction of the moving body 19, or even to the axis O.

[0078] Furthermore, the movable body 19 is preferably movable in the hook 39, so as to be able to slide when the movable body 19 performs an angular displacement, in the plane of the spiral spring 25.

[0079] For example, to be able to adjust the reference mark of the regulating member 1, it is necessary to be able to rotate the stud holder 31. Consequently, the spiral spring 25 rotates with the stud holder 31, and the mobile body 19 slides in the hook 39.

[0080] Thanks to such an actuation system 20, the marker can be adjusted without having to modify the position of the second timepiece component 30 relative to the plate of the movement. The mechanical connection between the second timepiece component 30 and the moving body 19 is maintained, regardless of the position of the moving body 19 relative to the second timepiece component 30.

[0081] Thus, this actuation system 20 makes it possible to adjust the rate and the reference mark independently of each other, while having a constant predetermined position of the second timepiece component in the movement, for example relative to the plate and the balance bridge 22.

[0082] The actuation system 20 further comprises adjustment means cooperating with the second timepiece component 30 so as to be able to move the movable part 37 of the second timepiece component 30.

[0083] As shown on the Figure 1 , the adjustment means comprise a pivoting adjustment rocker 45 arranged to move the movable part 37 of the second timepiece component 30. The adjustment rocker 45 is preferably arranged in a plane substantially perpendicular to the plane of the second timepiece component 30, and is in contact with the bulge 68 of the movable part 37.

[0084] The adjustment rocker 45 comprises a pivot arm 69 and a support arm 71 connected to a hub 72 of the pivoting adjustment rocker 45.

[0085] The support arm 71 cooperates with the movable part 37 of the second timepiece component 30 to move it mechanically by contact. The support arm 71 pushes back the bulge 68 of the movable part 37 to a greater or lesser extent to move it. Thus, the hook 39 pulls the movable body 19 to a greater or lesser extent, and therefore the levers 14, 26 of the balance spring 25. The adjustment lever 45 is configured to pivot in a plane substantially perpendicular to the plane of the second timepiece component 30.

[0086] The adjustment lever 45 is configured to be mounted on the movement plate via the hub 72, which can rotate around a barrel 73, made from the same material as the plate.

[0087] Thus, by the rotation of the adjustment lever 45 around the barrel 73, the movable part 37 moves closer to or further away from the fixed part 33, in a plane parallel to the plane of the plate, by the more or less pronounced deformation of the spring part 35 of the second timepiece component 30.

[0088] The adjustment means also comprise a control screw 70 mechanically connected to the pivot arm 69, in order to control the pivoting of the adjustment rocker 45. The axis of the control screw 70 is arranged in the plane of the adjustment rocker 45 in the direction of the pivot arm 69.

[0089] The control screw can be operated by means of a tool, for example a screwdriver 24, the end of which is shown in the Figure 1 .

[0090] Thus, by screwing or unscrewing the control screw 70, the adjustment lever 45 and the second clockwork component 30 are actuated to move the hook 39 and therefore the movable body 19 of the prestressing means 6.

[0091] The restoring force of the spring part 35 of the second clockwork component 30 pushes the adjustment lever 45 against the control screw 70. Thus, the pivot arm 69 of the adjustment lever 45 is held against the control screw 70.

[0092] In the figures, the control screw 70, the adjustment lever 45, the movable part 37 of the second clockwork component 30, and the levers 15, 26 are each in a first position, in which the hook 39 pulls little on the movable body 19.

[0093] In a second position, not shown in the figures, the control screw 70 pushes the pivot arm 69 of the adjustment lever 45, so that the support arm 71 in contact with the bulge 68, in turn pushes the movable part 37 of the second timepiece component 30 towards the fixed part 33 by deformation of the spring part 35. Thus, the hook 39 pulls on the movable body 19, and therefore on the levers 14, 26, which perform a centrifugal movement. In the deformed configuration of the spring part 35, the flexible blades of the two translation tables 51, 52 deform in opposite directions.

[0094] As shown in the figures, the second timepiece component 30 is mounted on the first timepiece component 22, so as to be substantially perpendicular to the first timepiece component 22.

[0095] The assembly 10 further comprises means 40 for assembling the second timepiece component 30, here the actuator, onto the first timepiece component 22, here the plate.

[0096] According to the invention, the assembly means 40 comprise positioning means 50 of the second component 30 on the first component 22 in a plane substantially parallel to the plane of the first component 22. Thus, the positioning means 50 prevent the second component 30 from moving on the first component 22, in the plane substantially parallel to the plane of the first component 22.

[0097] In this embodiment, the positioning means 50 comprise at least one first lug 41, preferably two lugs 41, 42, arranged on the second component 22, and at least one hole 43, preferably two holes 43, 44, arranged in the first component 22, so that each lug 41, 42 is introduced into a hole 43, 44 to position the second component 30 on the first component 22.

[0098] The two lugs 41, 42 are here arranged at two opposite ends of the actuator. In particular, they are arranged at the ends of the fixed part 33 of the second component 30, which is intended to be mounted on the first timepiece component 22.

[0099] Preferably, at least one lug 41 can be snapped into a hole 43. This lug 41 is, for example, deformable so that it can be inserted into the hole 43. The lug 41 comprises a protrusion at its end, which locks into the hole 43.

[0100] The lugs 41, 42 and the holes 42, 43 are arranged perpendicular to the plane of the plate.

[0101] The assembly means 40 further comprise support means 60 on the second component 30 to block the second component 30 on the first component 22, in a direction substantially orthogonal to the plane of the first component 22.

[0102] Thus, the second component 30 is held on the first component 22 to prevent it from moving away from the plate. The second component 30 is therefore assembled on the first component 22, and secured to the first component 22.

[0103] The support means 60 comprise an assembly body 46 mounted on the first component 22. The assembly means 40 comprise a screw 47 and the assembly body 46 comprises a passage 48 for assembling the assembly body 46 on the first component 22. The screw 47 is inserted through the passage 48 to screw the assembly body 46 into a hole 18 of the first component 22.

[0104] The assembly body 46 comprises a peripheral notch 27 cooperating with a projection 29 extending from the first component 22, in order to prevent the assembly body 46 from rotating around the screw 47.

[0105] The assembly body 46 comprises a rigid tab 49 extending to the second component 30 to press on the first component 22.

[0106] To this end, the second component 30 comprises a bearing face 64, on which the rigid tab 49 rests to apply a holding force of the second component 30 on the first component 22.

[0107] The second component 30 comprises an opening 58 allowing the rigid tab 49 to pass at least partly through the second component 30.

[0108] Furthermore, the opening 58 preferably comprises a vertical wall, against which the rigid tab 49 is retained, to prevent the rigid tab 49 from rotating with the assembly body 46.

[0109] In this embodiment, the opening 58 is arranged through the elastic part 35 of the second component 30, more precisely between the flexible blades 61 of the first translation table 51, so that the rigid tongue 49 presses on the bar 63 of the fixed part 33. The vertical wall is for example arranged at the base of a flexible blade 61 of the first translation table 51.

[0110] Naturally, the invention is not limited to the embodiments of regulating members described with reference to the figures, and variants could be envisaged without departing from the scope of the invention.
