Description

Technical Field

[0008] , , , , ,

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

[0002] More specifically, the present invention relates to an assembly of two timekeeping components for a timepiece movement.

Background Art

[0003] In most mechanical watches, such components are assembled together on a plate by known conventional means such as driving, screwing, encapsulation, or more rarely, adhesive bonding or brazing.

[0004] The components are typically mounted within the movement in a stack of continuous planes substantially parallel to the plate. The components are, for example, gears, bearings, etc.

[0005] Some components, particularly, for example, the rotating arbor for a gear and the balance for a balance wheel, must be mounted perpendicular to the plane of the plate. However, the rotating arbor and the balance are small in volume, so the assembly is easy.

[0006] However, some of the larger components are more difficult to assemble into the movement, especially when they must be mounted perpendicular to the plate.

[0007] Furthermore, these components may need to be coordinated with other components, for example, by connecting or engaging with other components of the movement, which makes the assembly of these components difficult.

[0008] Another problem associated with the assembly of timekeeping components is the possibility of play existing between the two components after they are assembled.

Modes for Carrying Out the Invention

[0030] In the following description, the subject matter of the present invention, which is a timepiece assembly, comprises means for assembling two timepiece components, and of the two timepiece components, the first component is a plate of the timepiece movement and the second component is an actuator of means for adjusting the speed regulating member. However, such an assembly may relate to other components of the timepiece movement and is in no way limited to these components or other components of the speed regulating member. <0^000114>

[0031] Figure 1 schematically shows one embodiment of a timekeeping movement, which comprises a plate with a recess and a speed regulating member 1. Such a movement is placed inside a timekeeping device, such as a clock.

[0032] The speed regulator 1 comprises an inertial mass, in this case a balance wheel 23, a hairspring 25 as an elastic return element for the inertial mass configured to vibrate the balance wheel 23, a balance staff, and a balance bridge (not shown). These elements are stacked from bottom to top in the following order: first timekeeping component 22, balance wheel 23, and hairspring 25.

[0033] The balance staff passes through the center of the balance wheel and hairspring 25. The balance staff is held in place by two shock-resistant bearings 28 positioned at both ends of the balance staff. The first bearing is located below the balance bridge within the plate 22, and the second bearing 28 is located inside the balance bridge. The balance bridge has a through hole that holds the second bearing 28 inside.

[0034] As shown in Figure 2, the hairspring 25 preferably extends substantially within a single plane. The hairspring 25 comprises a flexible strip 2 that is wound multiple times around its axis, and the strip 2 has a predetermined rigidity. The inner end 9 of the strip 2 is either integral with or assembled with a rigid support 3 called a hairspring ball. The rigid support 3 is substantially triangular in shape and is fitted around the balance staff.

[0035] The hairspring 25 further includes means for adjusting the rigidity of the hairspring 25. For example, the adjustment means may be operated by the user, particularly when assembling the regulating member into the timekeeping movement.

[0036] The adjustment means includes a flexible element 5, which is arranged in series with the strip 2, i.e., following the strip, preferably as an extension of the strip, and the flexible element 5 connects the outer end 4 of the strip 2 to the rigid support 53. The flexible element 5 is integral with the outer end 4 of the strip 2. The flexible element 5 is a separate element from the strip 2.

[0037] The flexible element 5 adds further rigidity to the strip 2. Preferably, the flexible element 5 is stiffer than the strip 2. In this case, the flexible element 5 is positioned as an extension of the strip 2. Preferably, the adjusting means and the strip 2 are integral parts or even made from the same material, such as silicon.

[0038] In this embodiment of the hairspring, the flexible element 5 comprises two flexible components 15 and 16, each connecting the strip 2 to the fixed support 53.

[0039] The two flexible components 15 and 16 are arranged axially symmetrically with respect to each other along the axis A of the hairspring 25. In other words, the two flexible components 15 and 16 are arranged symmetrically with respect to the axis A.

[0040] On the one hand, axis A substantially passes through the center O of the hairspring, and on the other hand, axis A preferably passes through the outer end 4 of the strip 2.

[0041] Therefore, the two flexible parts 15 and 16 are positioned on the outer circumference of the hairspring such that the two flexible parts 15 and 16 are positioned at the same distance from the center O of the hairspring 25.

[0042] The two flexible parts 15 and 16 are preferably positioned "mirror-like" relative to each other with respect to axis A. For this purpose, the two flexible parts 15 and 16 are preferably substantially identical.

[0043] Each of the flexible components 15 and 16 is equipped with a curved flexible vane 55, which preferably forms a semicircle and extends from the end of the fixed support 53. Each curved flexible vane 55 is also connected to the outer end 4 of the strip 2 by a flexible vane 7.

[0044] The fixed support 53 has a trapezoidal shape that is closed by the flexible vane 7.

[0045] The means for adjusting the hairspring 25 further includes a stress application means 6 for applying a variable force or torque to the flexible element 5. In this way, the stiffness of the hairspring can be adjusted. The torque or force is continuously adjustable thanks to the stress application means 6. In other words, the torque or force is not limited to a single point value. Therefore, the stiffness of the flexible element 5 can be adjusted with excellent precision.

[0046] Preferably, the stress application means 6 applies substantially the same force or torque to each flexible component 15, 16. The direction of the force is preferably substantially symmetrical.

[0047] The stress application means 6 further comprises two levers 14 and 26, each of which connects a curved blade 55 to the same movable body 19, and the movable body 19 is positioned on the opposite side of the hairspring 25 from the fixed support 53.

[0048] The movable body 19 is, for example, U-shaped, allowing it to engage with an actuator, which comprises, for example, a hook or finger, and the hook or finger is inserted into the U-shaped portion when the hook or finger is positioned tangentially to the levers 14, 26.

[0049] A variable force or torque is applied to the movable body 19. The variable force or torque is at least partially transmitted to the curved vanes 55 of the flexible parts 15 and 16 of the flexible element 5 via levers 14 and 26.

[0050] To enable the application of variable force or torque to the hairspring 25, the speed regulating member is equipped with a specific operating system 20.

[0051] In this embodiment, the speed regulator 1 includes a whisker support 31 equipped with a suspension whisker support 34. The whisker support 31 is mechanically connected to the flexible element 5 but does not obstruct the strip 2. The whisker support 31 surrounds the second support body 28. For this purpose, the whisker support 31 includes a central ring, which is positioned around the second support body 28 and rests on a chock support (not shown).

[0052] The whisker support 34 cooperates with the rigid support 55. In this way, the stress application means 6 and the flexible element 5 are supported by the whisker support 31, and the stress application means 6 and the flexible element 5 are suspended from the whisker support 31.

[0053] Furthermore, the hairspring holder 34 is firmly attached to the rigid support 55. In other words, the hairspring holder 34 is integral to the rigid support 55. The hairspring holder 34 and the hairspring 25 are assembled, for example, by adhesive, brazing, welding, deformation of metallic glass, or mechanical fastening.

[0054] The whisker holder 34 is movable relative to the first timing device component 22. For this purpose, the whisker holder support 31 can rotate around the second support body 28 relative to the first timing device component 22. The whisker holder support 31 can be displaced over an angular range of, for example, 20° or even 10°.

[0055] The vibration of the speed regulator 1 can be adjusted by displacing the whisker holder 34 relative to the first timing device component 22.

[0056] The actuation system 20 further comprises a second timing component 30, which is an actuator configured to actuate the movable body 19. The second timing component 30 is mechanically connected to the stress application means 6, and is configured to actuate the stress application means 6 by at least partially performing a substantially linear, preferably straight-line, displacement in a plane substantially perpendicular to the plate.

[0057] In other words, unlike the hairspring holder 31, which is rotated by rotating around an axis in a plane substantially parallel to the plate, at least a portion of the second timing component 30 moves substantially along a straight line. In this way, at least a portion of the second timing component 30 moves toward or away from the hairspring 25 in a direction substantially directed toward the hairspring.

[0058] Preferably, the direction of displacement of the second timing component 30 is substantially radial with respect to the balance wheel 23 and the hairspring 25. In this way, the straight line along which the second timing component 30 moves is directed toward the centers of the balance wheel 23 and the hairspring 25. Furthermore, this allows for speed setting independently of vibration setting. More specifically, the vibration of the speed regulator 1 can be adjusted by displacing the hairspring holder 34 relative to the first timing component 22.

[0059] The center of the second timing component 30 is offset from the speed regulator member. That is, the second timing component 30 is assembled at a certain distance from the center of the speed regulator member 1 and is connected only to the movable body 19 of the adjustment means. Therefore, the second timing component 30 is not directly assembled to the speed regulator member 1, for example, so that the whisker holder is assembled on the support body 28 of the speed regulator member 1.

[0060] Thus, the timekeeping movement comprises an assembly 10 which includes a first timekeeping component 22, in this case a plate, and a second timekeeping component 30, in this case an actuator for an adjustment means.

[0061] In this embodiment, the first timekeeping component 22 is a plate of the timekeeping movement, and the second timekeeping component 30 is an actuator. The second timekeeping component 30 is mounted on the first timekeeping component 22. The second timekeeping component 30 is mounted perpendicular to the first timekeeping component 22.

[0062] In Figure 3, the second timing device component 30 comprises, in particular, a fixed portion 33 mounted on the first timing device component 22, a portion 37 movable relative to the first timing device component 22 and connected to levers 14 and 26, and a spring portion 35 formed by a bent support that joins the movable portion 37 to the fixed portion 33. The fixed portion 33 and the movable portion 37 are preferably rigid. The fixed portion 33, the spring portion 35, and the movable portion 37 are preferably arranged in the same plane. Therefore, the second timing device component 30 is generally flat and extends substantially within a single plane.

[0063] To operate the movable body 19, the second timekeeping component 30 includes a hook 39 that engages with the U-shaped portion of the movable body 19. The hook 39 is closed, but may be partially open.

[0064] When the movable part 37 of the second timekeeping component 30 is displaced radially relative to the hairspring 25, the movable body 19 is pushed radially against the hairspring 25, thereby activating the levers 14 and 26. This changes the rigidity of the flexible element 5. This is because the displacement of the levers 14 and 26, which are rigidly connected to the movable body 18, applies a larger or smaller force or torque to the flexible element 5, changing its rigidity, and as a result, the rigidity of the hairspring 25 as a whole also changes. Therefore, the operating system 20 makes the speed-regulating member 1 speed-regulating.

[0065] The fixing portion 33 has a substantially elongated shape and includes a rod 63 intended to be assembled onto the first component 22.

[0066] As shown in the figure, the second timer component 30 is mounted on the first timer component 22 so as to be substantially orthogonal to the first timer component 22.

[0067] The spring portion 35 is positioned below the fixing portion 33 such that the spring portion 35 extends below the level of the first timekeeping component 22.

[0068] In this case, the spring section 35 comprises two translational stages 51 and 52 in which flexible vanes are arranged in series one after the other. The translational stages 51 and 52 are defined to be in series so that the displacement of each translational stage is at least partially accumulated.

[0069] Each translation stage 51, 52 comprises a pair of substantially parallel flexible vanes 61, 62 and rigid sections 56, 57 on which the pair of flexible vanes 61, 62 are mounted.

[0070] The first translational step 51 is positioned on the fixed portion 33 and comprises a first rigid section 56, the first rigid section 56 extending to be associated with the second translational step 52, the second translational step 52 being positioned head-to-tail, i.e., in opposite directions, together with the first translational step 51. In this way, the second pair of flexible vanes 62 are substantially parallel to the first pair of flexible vanes 61.

[0071] The second hardness category 57 is substantially parallel to the first hardness category 56, but is offset.

[0072] This arrangement of translational stages 51 and 52 allows the movable part 37 to be displaced substantially linearly, preferably in a straight line, while maintaining the small size of the second timing component 30.

[0073] The two translational stages, positioned head-to-tail, allow for mutual compensation of the vertical displacement of the hook 39 caused by each translational stage. In this way, the hook 39 remains at substantially the same height while moving.

[0074] The movable portion 37 extends from the second section 57. The movable portion 37 is preferably rigid. In this case, the movable portion 37 has an elbow-shaped portion, which is formed by a first section 66 positioned perpendicular to the second section 57, and a second section 67 that forms a right angle with the first section 66.

[0075] The hook 39 of the second timekeeping component 30 is located at the end of the branch of the second section 67. At the free end of the first section 66, the protrusion 68 acts as a support for moving the movable part 37.

[0076] By pressing the protrusion 68 somewhat firmly, the movable part 37 moves substantially parallel to the fixed part 33 thanks to the deformation of the translational steps 51 and 52 of the spring part 35.

[0077] In this way, the hook 39 pulls the levers 14 and 26 somewhat strongly via the movable body 19, activating a means for adjusting the rigidity of the flexible element 5.

[0078] The direction of displacement of the movable part 39 and the movable body 19 of the second timekeeping component 30 is substantially perpendicular to the direction of the movable body 19 or axis O.

[0079] Furthermore, the movable body 19 is preferably movable within the hook 39, so that the movable body 19 can slide when it undergoes angular displacement in the plane of the hairspring 25.

[0080] For example, in order to adjust the vibration of the speed regulator 1, the hairspring holder 31 must be rotatable. Therefore, the hairspring 25 rotates together with the hairspring holder 31, and the movable body 19 slides within the hook 39.

[0081] Thanks to such an operating system 20, oscillations can be adjusted without the need to adjust the position of the second timekeeping component 30 relative to the movement plate. The mechanical connection between the second timekeeping component 30 and the movable body 19 is maintained regardless of the position of the movable body 19 relative to the second timekeeping component 30.

[0082] Therefore, this operating system 20 allows for independent adjustment of speed and vibration while maintaining a fixed predetermined position of the second timekeeping component within the movement, for example, relative to the plate and balance wheel 22.

[0083] The operating system 20 further includes adjustment means that cooperate with the second timing component 30 to enable displacement of the movable part 37 of the second timing component 30.

[0084] As shown in Figure 1, the adjustment means comprises a pivot adjustment lever 45, which is positioned to displace a movable part 37 of the second timing component 30. Preferably, the adjustment lever 45 is positioned in a plane substantially perpendicular to the plane of the second timing component 30 and in contact with a protrusion 68 of the movable part 37.

[0085] The adjustment lever 45 has a pivot arm 69 and a support arm 71 connected to the hub 72 of the pivot adjustment lever 45.

[0086] The support arm 71 cooperates with the movable part 37 of the second timekeeping component 30, mechanically displacing the movable part 37 by contact. The support arm 71 pushes and moves the protrusion 68 of the movable part 37 to varying degrees. Thus, the hook 39 pulls the levers 14 and 26 of the movable body 19, and therefore the hairspring 25, to varying degrees. The adjustment lever 45 is configured to pivot in a plane substantially perpendicular to the plane of the second timekeeping component 30.

[0087] The adjustment lever 45 is configured to be mounted on the movement plate via a hub 72 and can rotate around a tube 73 which is manufactured integrally with the plate.

[0088] Therefore, by rotating the adjustment lever 45 around the tube 73, the movable part 37 moves toward or away from the fixed part 33 in a plane parallel to the plane of the plate, due to a more or less significant deformation of the spring part 35 of the second timing component 30.

[0089] The adjustment means further includes an adjustment screw 70 mechanically connected to a pivot arm 69 for adjusting the pivot of the adjustment lever 45. The axis of the adjustment screw 70 is positioned in the plane of the adjustment lever 45 in the direction of the pivot arm 69.

[0090] The adjustment screw can be operated using a tool, for example, a screwdriver 24 whose end is shown in Figure 1.

[0091] Therefore, by tightening or loosening the adjustment screw 70, the adjustment lever 45 and the second timing component 30 are activated, and the hook 39, and thus the movable body 19 of the stress application means 6, is moved.

[0092] The restoring force of the spring portion 35 of the second timing device component 30 presses the adjustment lever 45 against the adjustment screw 70. In this way, the pivot arm 69 of the adjustment lever 45 is held against the adjustment screw 70.

[0093] In the drawing, the adjustment screw 70, the adjustment lever 45, the movable part 37 of the second timing device component 30, and the levers 15 and 26 are each in a first position where the hook 39 lightly pulls the movable body 19.

[0094] In a second position (not shown), the adjustment screw 70 pushes the pivot arm 69 of the adjustment lever 45, and the support arm 71, which is in contact with the protrusion 68, pushes the movable part 37 of the second timer component 30 toward the fixed part 33 due to the deformation of the spring part 35. In this way, the hook 39 pulls the movable body 19, and therefore the levers 14 and 26, and performs displacement using centrifugal force. When the spring part 35 is in a deformed configuration, the flexible vanes of the two translation stages 51 and 52 deform in opposite directions.

[0095] As shown in the figure, the second timer component 30 is mounted on the first timer component 22 so as to be substantially orthogonal to the first timer component 22.

[0096] The assembly 10 further comprises means 40 for assembling a first timing device component 22, in this case a second timing device component 30, and in this case an actuator, onto a plate.

[0097] According to the present invention, the assembly means 40 includes means 50 for positioning the second component 30 on the first component 22 in a plane substantially parallel to the plane of the first component 22. Therefore, the positioning means 50 prevents the second component 30 from moving on the first component 22 in a plane substantially parallel to the plane of the first component 22.

[0098] In this embodiment, the placement means 50 comprises at least one first catch 41, preferably two catches 41 and 42, placed on the second component 22, and at least one hole 43, preferably two holes 43 and 44, placed within the first component 22, so that each catch 41 and 42 is inserted into the holes 43 and 44 to place the second component 30 on the first component 22.

[0099] In this case, the two catches 41 and 42 are located at the two opposite ends of the actuator. In particular, the two catches 41 and 42 are located at the ends of the fixing portion 33 of the second component 30, which is intended to be mounted on the first timer component 22.

[0100] Preferably, at least one catch 41 can be snapped into the hole 43. This catch 41 is deformable, for example, so that it can be inserted into the hole 43. The catch 41 has a projection at its end, which locks inside the hole 43.

[0101] The catches 41 and 42 and the holes 43 and 44 are arranged perpendicular to the plane of the plate.

[0102] The assembly means 40 further includes means 60 for supporting the second component 30 in order to lock the second component 30 onto the first component 22 in a direction substantially perpendicular to the plane of the first component 22.

[0103] Therefore, the second component 30 is held on the first component 22 so that the second component 30 does not detach from the board. The second component 30 is thus assembled on the first component 22 and firmly connected to the first component 22.

[0104] The support means 60 includes an assembly body 46 that is mounted on the first component 22. The assembly means 40 includes a screw 47, and the assembly body 46 includes a passage 48 for assembling the assembly body 46 to the first component 22. The screw 47 is inserted into the passage 48 and fastens the assembly body 46 to the hole 18 of the first component 22.

[0105] The assembly body 46 is provided with a periphery notch 27 that cooperates with a protrusion 29 extending from the first component 22, preventing the assembly body 46 from rotating around the screw 47.

[0106] The assembly body 46 is the first clock Component 22 against , second clock Component 30 Press It is equipped with a rigid tab 49.

[0107] For this purpose, the second component 30 includes a support surface 64 on which a rigid tab 49 rests, so as to apply a force that holds the second component 30 on the first component 22.

[0108] The second component 30 includes an opening 58 that allows the rigid tab 49 to pass through the second component 30 at least partially.

[0109] Furthermore, the opening 58 is provided with a vertical wall, and the rigid tab 49 is held against the vertical wall so as not to rotate together with the assembly body 46.

[0110] In this embodiment, the opening 58 is positioned through the elastic portion 35 of the second component 30, more precisely, between the flexible vanes 61 of the first translational step 51, so that the rigid tab 49 presses against the rod 63 of the fixed portion 33. For example, a vertical wall is positioned at the base of the flexible vanes 61 of the first translational step 51.

[0111] The present invention is not limited to the embodiments of the speed regulator described with reference to the drawings, and it goes without saying that alternative embodiments can be considered without departing from the scope of the present invention. [Explanation of Symbols]
