Abstract
Description
Technical Field
[0001] The present invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking.
[0002] More particularly, the present invention relates to an assembly of two watch components for a watch movement. Background Art
[0003] In most mechanical watches, the various components are assembled together on the mainplate by known conventional means (such as press-fitting, screwing, sleeving, or more rarely, gluing or welding).
[0004] These components are usually mounted in the movement, stacked in a series of planes substantially parallel to the mainplate. For example, these components are gears, bridges, etc.
[0005] Some components must be mounted perpendicular to the plane of the mainplate, especially for example the rotating arbors for gears or balance wheels and the balance staff. Due to the small size of the rotating arbors and balance staff, they are easy to assemble.
[0006] However, the assembly of some larger components in the movement is more complex, especially when they have to be assembled orthogonally to the mainplate.
[0007] In addition, they may need to interact with other components of the movement, for example by interlocking or meshing, which makes them difficult to assemble.
[0008] Another problem related to the assembly of watch components is that there may be play between two components after assembly. Summary of the Invention

[0012] Thanks to the present invention, an effective and simplified assembly of two clock components can be achieved, because the second clock component is only positioned on the first clock component by the positioning component and laterally held, and then the pressing component is arranged on the second clock component to lock the second clock component in place and assemble it on the first clock component.
[0013] These assembly devices are simple and effective to implement, because the positioning component places the second clock component in a plane substantially parallel to the plane of the first clock component, and the pressing component holds the second clock component in a second direction perpendicular to the aforementioned plane.
[0014] In addition, such an assembly makes it easy to assemble the clock component perpendicular to the motherboard.

[0016] According to a specific embodiment of the present invention, the positioning component includes at least one first catch arranged on the second clock component, preferably two catches, and at least one hole arranged in the first clock component, preferably two holes, so that each catch is inserted into one hole to assemble the two clock components.
[0017] According to a specific embodiment of the present invention, at least one catch can be snapped into the hole.
[0018] According to a specific embodiment of the present invention, the pressing component includes an assembly body arranged on the first clock component, and the second clock component includes a pressing surface, and the assembly body presses against the pressing surface to lock the second clock component in place.
[0019] According to a specific embodiment of the present invention, the assembly body includes a rigid tab for pressing against the second clock component.
[0020] According to a specific embodiment of the present invention, the second clock component has an opening through which the rigid tab can pass.
[0021] According to a specific embodiment of the present invention, the assembly device includes a screw, and the assembly body includes a passage for assembling the assembly body to the first clock component, and the first clock component is provided with an internal threaded hole for the screw.
[0022] According to a specific embodiment of the present invention, the second clock component includes a stationary part intended to be mounted on the first clock component and a movable part capable of moving relative to the first clock component.
[0023] According to a specific embodiment of the present invention, the stationary part includes the one or more catches.
[0024] According to a particular embodiment of the invention, the opening is arranged between the stationary part and the movable part.
[0025] According to a particular embodiment of the invention, the assembly body bears against the stationary part.
[0026] The invention also relates to a watch movement comprising such a watch assembly.
[0027] The invention also relates to a watch, such as a wristwatch, comprising such a watch movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the following description, the subject of the invention is a watch assembly provided with assembly means for assembling two watch parts, wherein the first watch part is the mainplate of a watch movement and the second watch part is an actuator of a device for regulating a speed - regulating mechanism. However, such an assembly can relate to other parts of a watch movement and is in no way limited to these parts or other parts of the speed - regulating mechanism.
[0035] Figure 1 A perspective view schematically shows an embodiment of a part of a watch movement, the watch movement comprising a mainplate provided with a recess and a speed - regulating mechanism 1. Such a movement is arranged, for example, in a watch (such as a wristwatch).
[0036] The speed regulating mechanism 1 includes an inertial mass body which is a ring-shaped balance wheel 23 in this example, a hairspring 25 which is an elastic restoring element for the inertial mass body and is configured to oscillate the inertial mass body, a balance staff, and a balance cock (not shown in the figure). These elements are stacked in the following order from bottom to top: the first watch component 22, the balance wheel 23, and the hairspring 25.
[0037] The balance staff passes through the centers of the balance wheel and the hairspring 25. The balance staff is held by two shock-resistant bearings 28 which are arranged at both ends of the balance staff. The first bearing is arranged in the movement plate 22 below the balance cock, and the second bearing 28 is arranged in the balance cock. The balance cock has a through hole, and the second bearing 28 is held in the through hole.
[0038] As Figure 2 shown, the hairspring 25 preferably extends substantially in one plane. The hairspring 25 includes a flexible strip 2 wound around itself for multiple turns, and the strip 2 has a predetermined stiffness. The inner end portion 9 of the strip 2 is integrally formed with or assembled to a rigid support 3, and the rigid support 3 is generally referred to as an inner stud. The rigid support 3 is generally triangular in shape and is passed through by the balance staff.
[0039] The hairspring 25 further includes an adjusting device for adjusting its stiffness. For example, when the speed regulating mechanism is installed in a watch movement, the adjusting device can be actuated by the user in particular.
[0040] The adjusting device includes a flexible element 5 which is arranged in series with the strip 2, that is, following the strip, preferably as an extension thereof, and the flexible element 5 connects the outer end portion 4 of the strip 2 to the rigid support 53. The flexible element 5 is integrally formed with the outer end portion 4 of the strip 2. The flexible element 5 is an element distinct from the strip 2.
[0041] The flexible element 5 adds additional stiffness to the strip 2. The flexible element 5 is preferably stiffer than the strip 2. In this example, the flexible element 5 is arranged as an extension of the strip 2. Preferably, the adjusting device and the strip 2 are a single piece, or even made of the same material (such as silicon).
[0042] In this hairspring embodiment, the flexible element 5 includes two flexible portions 15, 16, and each flexible portion connects the strip 2 to the fixed support 53.
[0043] The two flexible portions 15, 16 are arranged relative to each other in a manner symmetric about the axis A of the hairspring 25. In other words, the two flexible portions 15, 16 are positioned symmetrically about the axis A.
[0044] On the one hand, the axis A substantially passes through the center O of the hairspring, and on the other hand, the axis A preferably passes through the outer end portion 4 of the strip 2.
[0045] Thus, two flexible portions 15, 16 are arranged on the outer periphery of the hairspring such that the two flexible portions 15, 16 are arranged at the same distance from the center O of the hairspring 25.
[0046] The two flexible portions 15, 16 are preferably arranged in a "mirror image" position with respect to each other about the axis A. For this purpose, the two flexible portions 15, 16 are preferably substantially identical.
[0047] Each of the flexible portions 15, 16 includes a curved flexible blade 55 which preferably forms a semi-circle and extends from the end of the fixed support 53. Each curved flexible blade 55 is also connected to the outer end portion 4 of the strip 2 by a flexible blade 7.
[0048] The fixed support 53 is trapezoidal and is enclosed by the flexible blade 7.
[0049] The adjusting device for adjusting the hairspring 25 further includes a prestressing device 6 for applying a variable force or torque to the flexible element 5. In this way, the stiffness of the hairspring can be adjusted. Thanks to the prestressing device 6, the torque or force can be continuously adjusted. In other words, the torque or force is not limited to a point value. Therefore, the stiffness of the flexible element 5 can be adjusted very precisely.
[0050] Preferably, the prestressing device 6 applies substantially the same force or torque to each of the flexible portions 15, 16. The direction of the force is preferably substantially symmetric.
[0051] The prestressing device 6 further includes two rods 14, 26, each of which connects the curved blade 55 to the same movable body 19, and the movable body 19 is arranged on the other side of the hairspring 25 relative to the fixed support 53.
[0052] The movable body 19 is, for example, U-shaped, so as to allow it to engage with an actuator which is, for example, provided with a hook or finger inserted into the U-shape, since the U-shape is arranged tangentially to the rods 14, 26.
[0053] A variable force or torque is applied to the movable body 19. The variable force or torque is at least partially transmitted via the rods 14, 26 to the curved blades 55 of the flexible portions 15, 16 of the flexible element 5.
[0054] In order to be able to apply a variable force or torque to the hairspring 25, the speed regulating mechanism includes a specific actuation system 20.
[0055] In this embodiment, the speed regulating mechanism 1 includes an outer stud holder 31 provided with a suspended outer stud 34. The outer stud holder 31 is mechanically connected to the flexible element 5 but does not block the strip 2. The outer stud holder 31 surrounds the second bearing 28. For this purpose, the outer stud holder 31 includes a central ring arranged around the second bearing 28, and the central ring rests on the balance cock (not shown).
[0056] The outer stud 34 cooperates with the rigid support 55. In this way, the prestressing device 6 and the flexible element 5 are supported by the outer stud holder 31 from which they are suspended.
[0057] Furthermore, the outer stud 34 is rigidly attached to the rigid support 55. In other words, the outer stud 34 and the rigid support 55 are integral. The outer stud 34 and the hairspring 25 are assembled, for example, by gluing, soldering, welding, metallic glass deformation or mechanical fastening.
[0058] The outer stud 34 is movable relative to the first watch component 22. To this end, the outer stud holder 31 is rotatable relative to the first watch component 22 about the second bearing 28. The outer stud holder 31 can be displaced, for example, over an angular range of 20° or even 10°.
[0059] By displacing the outer stud 34 relative to the first watch component 22, it is possible to adjust the beat of the speed control mechanism 1.
[0060] The actuation system 20 further includes a second watch component 30 which is an actuator configured to actuate the movable body 19. The second watch component 30 is mechanically connected to the prestressing device 6 and is configured to perform at least partially a substantially linear, preferably rectilinear, displacement in a plane substantially perpendicular to the mainplate in order to actuate the prestressing device 6.
[0061] In other words, at least a part of the second watch component 30 moves substantially in a straight line, which is different, for example, from the outer stud holder 31 which rotates by turning about an axis in a plane substantially parallel to the mainplate. Thus, at least a part of the second watch component 30 moves towards or away from the hairspring 25 in a direction substantially oriented towards the hairspring.
[0062] Preferably, the displacement direction of the second watch component 30 is substantially radial with respect to the balance wheel 23 and the hairspring 25. Thus, the straight line along which the second watch component 30 moves points towards the center of the balance wheel 23 and the hairspring 25. This also makes the setting of the rate difference independent of the setting of the beat. More specifically, by displacing the outer stud 34 relative to the first watch component 22, the beat of the speed control mechanism 1 can be adjusted.
[0063] The second watch component 30 is eccentric with respect to the speed control mechanism, i.e., the second watch component 30 is mounted at a certain distance from the center of the speed control mechanism 1 and is only connected to the movable body 19 of the regulating device. Thus, the second watch component 30 is not directly mounted on the speed control mechanism 1, for example like the outer stud holder which is located on the bearing 28 of the speed control mechanism.
[0064] Thus, the timepiece movement includes a component 10, which includes a first timepiece part 22 and a second timepiece part 30. In this example, the first timepiece part 22 is a mainplate, and the second timepiece part 30 is an actuator of the regulating device.
[0065] In the present embodiment, the first timepiece part 22 is the mainplate of the timepiece movement, and the second timepiece part 30 is the actuator. The second timepiece part 30 is mounted on the first timepiece part 22. The second timepiece part 30 is mounted perpendicular to the first timepiece part 22.
[0066] In Figure 3 it, the second timepiece part 30 particularly includes a stationary part 33, a movable part 37, and a spring part 35. The stationary part 33 is mounted on the first timepiece part 22. The movable part 37 is able to move relative to the first timepiece part 22 and is connected to rods 14, 26. The spring part 35 is formed by a flexible bearing, which connects the movable part 37 to the stationary part 33. The stationary part 33 and the movable part 37 are preferably rigid. The stationary part 33, the spring part 35, and the movable part 37 are preferably arranged in the same plane. Thus, the second timepiece part 30 is generally flat and extends substantially in one plane.
[0067] In order to actuate the movable body 19, the second timepiece part 30 includes a hook part 39 that engages with the U - shape of the movable body 19. The hook part 39 is closed, but it can also be partially open.
[0068] By the radial displacement of the movable part 37 of the second timepiece part 30 relative to the hairspring 25, the movable body 19 can be pulled or pushed radially relative to the hairspring 25, thereby actuating the rods 14, 26. This changes the stiffness of the flexible element 5 because the displacement of the rods 14, 26, which are rigidly connected to the movable body 19, exerts a greater or lesser force or torque on the flexible element 5, causing the stiffness of the flexible element 5 to change. Thus, the stiffness of the entire hairspring 25 also changes. Therefore, the actuation system 20 enables the adjustment of the rate difference of the speed - regulating mechanism 1.
[0069] The stationary part 33 has a substantially elongated shape and includes a bar 63 intended to be mounted on the first timepiece part 22.
[0070] As shown in the figure, the second timepiece part 30 is mounted on the first timepiece part 22 so as to be substantially perpendicular to the first timepiece part 22.
[0071] The spring part 35 is arranged above the stationary part 33, so that the spring part 35 extends above the horizontal position of the first timepiece part 22.
[0072] In this example, the spring part 35 includes two translation stages / tables 51, 52 with flexible blades, which are arranged in series one after the other. They are defined as "in series" because the displacements of each translation stage are at least partially cumulative.
[0073] Each translation stage 51, 52 includes a pair of flexible blades 61, 62 that are substantially parallel, and rigid sections 56, 57 on which the pair of flexible blades 61, 62 are mounted.
[0074] The first translation stage 51 is arranged on the stationary part 33 and includes a first rigid section 56 that is elongated so as to be associated with the second translation stage 52, and the second translation stage 52 is arranged end-to-end with the first translation stage 51 (i.e., arranged in the opposite direction). In this way, the second pair of flexible blades 62 is substantially parallel to the first pair of flexible blades 61.
[0075] The second rigid section 57 is substantially parallel to the first rigid section 56, but is offset relative to the first rigid section 56.
[0076] With this arrangement of the translation stages 51, 52, the movable part 37 can be displaced in a substantially linear, preferably straight, manner while keeping the second clockwork part 30 compact.
[0077] By arranging the two translation stages end-to-end, the vertical deviations of the respective hooks 39 generated can compensate for each other. In this way, the hooks 39 will remain at substantially the same height when moving.
[0078] The movable part 37 extends from the second section 57. The movable part 37 is preferably rigid. In this example, the movable part 37 has an elbow shape formed by a first section 66 arranged perpendicular to the second section 57 and a second section 67 forming a right angle with the first section 66.
[0079] The hook 39 of the second clockwork part 30 is located at the branched end of the second section 67. At the free end of the first section 66, the projection 68 serves as a support for moving the movable part 37.
[0080] By pressing the projection 68 with more or less force, the movable part 37 moves substantially parallel to the stationary part 33, which benefits from the deformation of the translation stages 51, 52 of the spring part 35.
[0081] In this way, the hook 39 pulls the rods 14, 26 with more or less force via the movable body 19 in order to actuate the adjusting device for adjusting the stiffness of the flexible element 5.
[0082] The displacement direction of the movable part 37 of the second clockwork part 30 and of the movable body 19 is substantially orthogonal to the direction of the movable body 19, or orthogonal to the axis O.
[0083] Furthermore, the movable body 19 is preferably able to move in the hook part 39 such that, when the movable body 19 undergoes an angular displacement in the plane of the hairspring 25, the movable body 19 can slide.
[0084] For example, in order to be able to adjust the beat of the speed regulation mechanism 1, the outer stud holder 31 must be able to rotate. Thus, the hairspring 25 rotates with the outer stud holder 31, and the movable body 19 slides in the hook part 39.
[0085] Thanks to this actuation system 20, the beat can be adjusted without changing the position of the second clockwork part 30, in particular its position relative to the movement mainplate. Whatever the position of the movable body 19 relative to the second clockwork part 30, the mechanical connection between the second clockwork part 30 and the movable body 19 is maintained.
[0086] Thus, this actuation system 20 makes it possible to adjust the rate difference and the beat independently of each other while maintaining a constant predetermined position of the second clockwork part in the movement, for example relative to the mainplate and relative to the balance cock 22.
[0087] The actuation system 20 also includes an adjustment member which cooperates with the second clockwork part 30 so as to be able to displace the movable part 37 of the second clockwork part 30.
[0088] As Figure 1 shown, the adjustment member includes a pivoting adjustment lever 45 which is arranged to displace the movable part 37 of the second clockwork part 30. The adjustment lever 45 is preferably arranged in a plane substantially perpendicular to the plane of the second clockwork part 30 and is in contact with the projection 68 of the movable part 37.
[0089] The adjustment lever 45 has a pivoting arm 69 and a support arm 71 connected to the hub 72 of the pivoting adjustment lever 45.
[0090] The support arm 71 cooperates with the movable part 37 of the second clockwork part 30 so as to mechanically displace the movable part 37 by contact. The support arm 71 pushes the projection 68 of the movable part 37 to move it to a greater or lesser extent. The hook part 39 thus pulls the movable body 19, thereby pulling the rods 14, 26 of the hairspring 25 to a greater or lesser extent. The adjustment lever 45 is configured to pivot in a plane substantially perpendicular to the plane of the second clockwork part 30.
[0091] The adjustment lever 45 is configured to be mounted on the movement mainplate via the hub 72, the hub 72 being rotatable about a pipe part 73 integrally formed with the mainplate.
[0092] Thus, by rotating the adjusting lever 45 about the pipe fitting 73, the movable part 37 moves toward or away from the stationary part 33 in a plane parallel to the plane of the machine plate by virtue of a greater or lesser degree of deformation of the spring part 35 of the second clockwork part 30.
[0093] The adjusting part further includes a control screw 70 mechanically connected to the pivot arm 69 so as to control the pivoting of the adjusting lever 45. The axis of the control screw 70 is arranged in the plane of the adjusting lever 45 in the direction of the pivot arm 69.
[0094] The control screw can be operated using a tool (such as a screwdriver 24), the end of which is shown in Figure 1 shown.
[0095] Thus, by tightening or loosening the control screw 70, the adjusting lever 45 and the second clockwork part 30 are actuated to move the hook part 39, thereby moving the movable body 19 of the prestressing device 6.
[0096] The restoring force of the spring part 35 of the second clockwork part 30 pushes the adjusting lever 45 against the control screw 70. In this way, the pivot arm 69 of the adjusting lever 45 remains in contact with the control screw 70.
[0097] In the figure, the control screw 70, the adjusting lever 45, the movable part 37 of the second clockwork part 30, and the rods 14, 26 are all in the first position, where the hook part 39 slightly pulls on the movable body 19.
[0098] In a second position not shown in the figure, the control screw 70 pushes the pivot arm 69 of the adjusting lever 45, such that the support arm 71 in contact with the projection 68 then pushes the movable part 37 of the second clockwork part 30 toward the stationary part 33 through the deformation of the spring part 35. In this way, the hook part 39 pulls the movable body 19, thereby pulling the rods 14, 26, which undergo a centrifugal displacement. When the spring part 35 is in a deformed configuration, the flexible blades of the two translation stages 51, 52 deform in opposite directions.
[0099] As shown in the figure, the second clockwork part 30 is mounted on the first clockwork part 22 in a manner substantially perpendicular to the first clockwork part 22.
[0100] The assembly 10 further includes an assembly device 40 for assembling the second clockwork part 30 (in this example, the actuator) on the first clockwork part 22 (in this example, the machine plate).
[0101] According to the present invention, the assembly device 40 includes a positioning member 50 for positioning a second watch part 30 on a first watch part 22 in a plane substantially parallel to the plane of the first watch part 22. Thus, the positioning member 50 prevents the second watch part 30 from moving on the first watch part 22 in a plane substantially parallel to the plane of the first watch part 22.
[0102] In this embodiment, the positioning member 50 includes at least one first jaw 41, preferably two jaws 41, 42, arranged on the second watch part 30, and at least one hole 43, preferably two holes 43, 44, arranged in the first watch part 22, such that each jaw 41, 42 is inserted into a hole 43, 44 to position the second watch part 30 on the first watch part 22.
[0103] In this example, the two jaws 41, 42 are arranged at opposite ends of the actuator. Specifically, they are arranged at the ends of the stationary part 33 of the second watch part 30, which is intended to be mounted on the first watch part 22.
[0104] Preferably, at least one jaw 41 can be snapped into the hole 43. The jaw 41 is deformable, for example, so that it can be inserted into the hole 43. The jaw 41 has a protrusion at its end, which locks within the hole 43.
[0105] The jaws 41, 42 and the holes 43, 44 are arranged perpendicular to the plane of the main board.
[0106] The assembly device 40 further includes a pressing member 60 for pressing against the second watch part 30 so as to lock the second watch part 30 on the first watch part 22 in a direction substantially orthogonal to the plane of the first watch part 22.
[0107] In this way, the second watch part 30 is held on the first watch part 22 to prevent it from moving away from the main board. The second watch part 30 is thus assembled on the first watch part 22 and is rigidly connected to the first watch part 22.
[0108] The pressing member 60 includes an assembly body 46 mounted on the first watch part 22. The assembly device 40 includes a screw 47, and the assembly body 46 includes a passage 48 for assembling the assembly body 46 to the first watch part 22. The screw 47 is inserted through the passage 48 to threadedly connect the assembly body 46 within a hole 18 in the first watch part 22.
[0109] The assembly body 46 includes a peripheral notch 27, which cooperates with a protrusion 29 extending from the first watch part 22 to prevent the assembly body 46 from rotating about the screw 47.
[0110] The assembly body 46 includes a rigid tab 49 that extends to the second timepiece component 30 to bear against the second timepiece component 30.
[0111] To this end, the second timepiece component 30 includes a bearing surface 64 on which the rigid tab 49 rests to exert a force for holding the second timepiece component 30 on the first timepiece component 22.
[0112] The second timepiece component 30 includes an opening 58 to allow the rigid tab 49 to pass through the second timepiece component 30 at least partially.
[0113] In addition, the opening 58 preferably includes a vertical wall against which the rigid tab 49 is held to prevent the rigid tab 49 from rotating with the assembly body 46.
[0114] In this embodiment, the opening 58 is arranged to pass through the elastic part 35 of the second timepiece component 30. More precisely, the opening 58 is arranged between the flexible blades 61 of the first translation stage 51 such that the rigid tab 49 bears against the bar 63 of the stationary part 33. For example, the vertical wall is arranged at the base of the flexible blades 61 of the first translation stage 51.
[0115] It goes without saying that the present invention is not limited to the embodiments of the speed control mechanism described with reference to the accompanying drawings, and alternatives can be considered without departing from the scope of the present invention.
