Technical Field

[0001] The utility model relates to the field of clock and watch manufacturing, and more specifically to the field of mechanical clock and watch manufacturing.

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

[0003] In most mechanical watches, the various components are assembled together on the plate by known conventional methods, for example by pressing, screwing, gluing or casing.

[0004] The components are usually mounted in the movement in a stacked manner in a continuous plane substantially parallel to the plate. Examples of these components include gears, bridges, etc.

[0005] Some parts must be mounted perpendicular to the plane of the plate, in particular axes of rotation, such as those for gears or for balance wheels. Axles are easy to assemble due to their small size.

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

[0007] Furthermore, they may need to interact, such as interlock or mesh, with other parts of the movement, making them difficult to assemble.

[0008] Another problem associated with the assembly of watch components is that a gap may exist between two components after assembly. Utility Model Content

In fact, the elastic element stops and holds the column of the first timepiece part, so that the two parts are connected to each other without any gap in between. In fact, the elastic element allows to absorb any gap that may exist between the two parts.

[0037] In the following description, the watch assembly as the subject of the present invention is provided with a device for fastening two watch parts of the speed regulating mechanism together. However, this assembly can involve other parts of the watch movement and is not limited to these parts or other parts of the speed regulating mechanism.

[0038] Figures 1 to 3 Schematically shows an embodiment of a regulating organ 1 to be arranged in a clock movement, the clock movement comprising a plate (not shown) provided with a housing. For example, such a movement is arranged in a clock such as a watch.

[0039] The regulating mechanism 1 comprises: an inertial mass, in this case an annular balance wheel 23; a hairspring 25 as an elastic reset element of the inertial mass, which is configured to cause the inertial mass to oscillate; a balance staff 24; and a first watch component 22, in this case a balance cock. These components are stacked in the following order from bottom to top: balance wheel 23, hairspring 25 and first watch component 22.

[0040] The balance shaft 24 passes through the center of the balance wheel, the hairspring 25 and the first watch component 22. The balance shaft 24 is held by two shock-absorbing bearings 28 arranged at both ends of the balance shaft 24. The first bearing is arranged below the first watch component 22, and the second bearing 28 is arranged in the first watch component 22. The first watch component 22 is provided with a through hole, and the second bearing 28 is held in the through hole.

[0041] like Figure 3 and 4 As shown, the balance spring 25 preferably extends substantially in one plane. The balance spring 25 comprises a flexible strip 2 wound several times around itself, the strip 2 having a predetermined rigidity. The inner end 9 of the strip 2 is integral with or assembled to a rigid support 3, which is usually called a collet. The rigid support 3 is substantially triangular and is assembled around the balance staff 24.

[0042] Balance spring 25 also includes adjustment means for adjusting its stiffness. This adjustment means can be actuated by the user, for example, when the regulating organ is installed in a timepiece movement.

[0043] The adjustment means comprise a flexible element 5 arranged in series with the strip 2, i.e. following it, preferably as an extension of it, connecting the outer end 4 of said strip 2 to the rigid support 17. The flexible element 5 is integral with the outer end 4 of the strip 2. The flexible element 5 is an element distinct from the strip 2.

[0044] The flexible element 5 adds additional rigidity to the strip 2. The flexible element 5 is preferably stiffer than the strip 2. Here, the flexible element 5 is arranged as an extension of the strip 2. Preferably, the adjustment device is integral with the strip 2 or is made of the same material, such as silicone.

[0045] Flexible element 5 of balance spring 25 comprises a first flexible blade 19 and a movable semi-rigid portion 18 extending from the outer end of strap 2 and connected to first flexible blade 19, preferably on the same side as rigid portion 18. First flexible blade 19 is also connected to rigid support 17.

[0046] Rigid support 17 is L-shaped, with a first leg 46 of the L serving as connection to first flexible blade 19 and a second leg 47 of the L facing away from first flexible blade 19 so that it can be assembled to a timepiece movement.

[0047] The adjustment device of the balance spring 25 also comprises a prestressing device 6 for applying a variable force or torque to the flexible element 5. In this way, the stiffness of the balance spring can be adjusted. Thanks to the prestressing device 6, the torque or force can be adjusted continuously. In other words, the torque or force is not limited to an isolated value. Therefore, the stiffness of the flexible element 5 can be adjusted very accurately.

[0048] The prestressing means 6 comprise a second flexible blade 21 which is arranged on the opposite side of the rigid portion 18 and in the extension of the first flexible blade 19 .

[0049] The other end of the second flexible blade 21 is connected to a curved rod 14 extending around the strip 2. In addition to the second flexible blade 21, the rod 14 is also connected to a semi-rigid structure 27 attached to the rigid support 17. When the rod 14 is actuated by a force or torque, the semi-rigid structure 27 is partially deformed.

[0050] The force or torque is exerted on the free end 15 of the rod 14 . In this way, the rod 14 of the prestressing device 6 transmits the force or torque to the flexible element 5 via the second flexible blade 21 and the semi-rigid structure 27 , so as to modify the stiffness of the balance spring 25 .

[0051] In order to be able to apply a variable force or torque to balance spring 25 , the regulating organ comprises a particular actuation system 20 according to the invention.

[0052] exist Figures 1 to 3 In the embodiment shown, regulating organ 1 comprises a stud holder 31 provided with a suspended stud 34. Stud holder 31 is mechanically connected to flexible element 5 but does not block strap 2. Stud holder 31 surrounds second bearing 28. To this end, stud holder 31 comprises a central ring 38 arranged around second bearing 28 and resting on first timepiece part 22.

[0053] The stud 34 cooperates with the second leg 47 of the rigid support 17. In this way, the prestressing means 6 and the flexible element 5 are supported by the stud holder 31 from which they are suspended.

[0054] Furthermore, stud 34 is rigidly attached to rigid support 17. In other words, stud 34 is integral with rigid support 17. Stud 34 and balance spring 25 are assembled, for example, by gluing, soldering, welding, deformation of metallic glass or mechanical fastening.

[0055] Stud 34 is movable relative to first timepiece component 22. To this end, stud holder 31 is rotatable relative to first timepiece component 22 about second bearing 28. Stud holder 34 is displaceable over an angular range of 20° or even 10°, for example.

[0056] By displacing the stud 34 relative to the first timepiece component 22 , the deflection of the speed regulating mechanism 1 can be adjusted.

[0057] Actuation system 20 also comprises a second clockwork part 30, which is an actuator configured to actuate said lever 14. Second clockwork part 30 is mechanically connected to prestressing means 6 and is configured to perform, at least partially, a substantially linear, preferably rectilinear, displacement in a plane substantially perpendicular to the plate, in order to actuate prestressing means 6.

[0058] In other words, at least a portion of second timepiece component 30 moves substantially along a straight line in a plane substantially parallel to the plate, unlike stud holder 31 of the balance spring which rotates, for example, by turning about an axis. In this way, at least a portion of second timepiece component 30 moves towards or away from balance spring 25 in a direction substantially oriented towards the balance spring.

[0059] Preferably, the direction of displacement of second horological component 30 is substantially radial relative to balance wheel 23 and balance spring 25. In this way, the straight line along which second horological component 30 moves is directed toward the center of balance wheel 23 and balance spring 25. This also makes it possible to set the travel time independently of the setting of the deflection.

[0060] Second timepiece component 30 is eccentric with respect to the regulating organ, i.e. it is mounted at a distance from the centre of regulating organ 1 and is connected only to rod 14 of the regulating device. Second timepiece component 30 is therefore not mounted directly on regulating organ 1, for example on a bearing 28 of regulating organ 1 like a stud holder.

[0061] The regulating organ thus comprises an assembly comprising a first timepiece component 22 and a second timepiece component 30 , in this case an actuator.

[0062] In this embodiment, the first watch component 22 is a balance cock, and the second watch component 30 is an actuator. The second watch component 30 is mounted on the first watch component 22. The second watch component 30 is mounted perpendicular to the first watch component 22. More specifically, the second watch component 30 is assembled on the edge of the first watch component 22.

[0063] exist Figure 5 and 6 , the second watch component 30 comprises in particular a stationary portion 33 mounted on the first watch component 22, a movable portion 37 movable relative to the first watch component 22 and connected to the rod 14, and a spring portion 35 formed by a flexible guide, the spring portion 35 connecting the movable portion 37 to the stationary portion 33. The stationary portion 33 and the movable portion 37 are preferably rigid. The stationary portion 33, the spring portion 35 and the movable portion 37 are arranged in the same plane. Therefore, the second watch component 30 is flat overall and extends substantially in one plane.

[0064] In order to actuate said stem 14, second timepiece part 30 comprises a hook 39 engaging stem 14, mounted on movable part 37. Hook 39 at least partially surrounds stem 14, but may also be closed around it.

[0065] The radial displacement of the movable part 37 of the second horological component 30 pulls or pushes the rod 14 radially relative to the balance spring 25. This changes the stiffness of the flexible element 5, since the displacement of the rod exerts a greater or lesser force or torque on the flexible element 5, causing a change in the stiffness of the flexible element 5 and therefore of the balance spring 25 as a whole. Thus, the actuation system 20 allows the regulation of the rate error of the regulating organ 1.

[0066] The assembly also comprises assembly means for assembling the first timepiece component 22 with the second timepiece component 30 .

[0067] According to the invention, the assembly device comprises at least one first column 43 arranged on the first timepiece component 22 , and at least one first notch 41 arranged on the second timepiece component 30 .

[0068] Here, the stationary part 33 has a substantially square shape and is provided with at least one attachment recess 41, preferably two attachment recesses 41, 42, each intended to receive a stud 43, 44 extending from the first timepiece component 22. The attachment recesses 41, 42 are arranged on diagonally opposite sides of the stationary part 33, for example.

[0069] Each recess 41, 42 is provided with a flexible element 48, 49, in this case a flexible tongue, which is arranged in the recess 41, 42. The flexible element 48, 49 is arranged along the inner side wall of each recess, wherein each tongue extends a short distance along the side wall. In addition, the flexible tongues 48, 49 can improve the positioning accuracy by occupying the positioning gap of the pillars 43, 44 in the recesses 41, 42 (preferably in the same direction).

[0070] When the posts 43, 44 are inserted into the recesses 41, 42, the flexible members 48, 49 are deformed to allow the posts to be inserted and apply pressure to the posts 43, 44 to hold them in the recesses 41, 42. By the pressure of the flexible members 48, 49 on the posts 43, 44, each post 43, 44 is held in the recesses 41, 42.

[0071] The distance between the flexible elements 48,49 and the walls of the recesses 41,42 is smaller than the diameter of the pillars 43,44 to obtain a pressure of the flexible elements 48,49 against the pillars 43,44. The width of the interior of the recesses 41,42 is at least equal to the diameter of the pillars 43,44.

[0072] In the present embodiment, the notches 41 , 42 pass perpendicularly to the plane of the second timepiece component 30 . Thus, when the studs 43 , 44 are inserted into the notches 41 , 42 , the studs 43 , 44 pass through the second timepiece component 30 .

[0073] The first recess 41 is arranged at one corner of the stationary portion 33 and is open at the side so that it can slide laterally around the first pillar 43. The second recess 42 is closed and can receive the second pillar 44 by inserting it.

[0074] The open first notch 41 is rectangular and is intended to align the second horological component 30 with the first horological component 22 . The second notch 42 is triangular and is intended to center the second horological component 30 on the first horological component 22 .

[0075] As shown, the second timepiece component 30 is mounted on the first timepiece component 22 so as to be substantially perpendicular to the plate and the first timepiece component 22. Thus, the second timepiece component 30 is mounted on the edge of the first timepiece component 22.

[0076] Spring portion 35 is arranged below stationary portion 33 such that it extends below the level of first timepiece component 22 .

[0077] In this example, the spring portion 35 comprises a plurality of translation stages / translation stages 51, 52, 53, 54 with flexible blades arranged in series one after the other. They are defined as "in series" because the displacement of each translation stage is at least partially cumulative.

[0078] Each translation stage 51, 52, 53, 54 comprises a pair of substantially parallel flexible blades 61, 62, 63, 64, and a rigid section 56, 57, 58, 59 on which the pair of flexible blades 61, 62, 63, 64 are mounted.

[0079] The first translation stage 51 is arranged below the stationary part 33 and has a first rigid section 56 which is lengthened so as to be associated with the second translation stage 52 which is arranged end to end with the first translation stage 51. In this way, the second pair of flexible blades 52 is substantially parallel to the first pair of flexible blades 51. The second rigid section 57 is substantially parallel to the first rigid section 56 but offset by half the length of the first rigid section 56.

[0080] The second rigid section 57 is also lengthened to associate the third translation stage 53 with the second translation stage 52 in an end-to-end arrangement and thus the third translation stage 53 is substantially parallel to the first translation stage 51. The third pair of flexible blades 63 is substantially parallel to the first and second pairs of flexible blades 61,62.

[0081] The second timepiece component 30 includes a fourth translation stage 54, which is arranged on a different side of the first translation stage 51 from the second translation stage 52 and the third translation stage 53. The fourth translation stage 54 is arranged end to end with the third translation stage 53.

[0082] In this manner, the fourth pair of flexible blades 64 are substantially parallel to the other pairs of flexible blades, and the fourth section 59 is arranged in substantially the same direction as the second section 57 .

[0083] The third translation stage 53 and the fourth translation stage 54 are connected by an arm 55 , which extends from the third section 58 and passes under the first rigid section 56 of the first translation stage 51 .

[0084] This arrangement of translation stages 51 , 52 , 53 and 54 enables movable portion 37 to be displaced in a substantially linear, preferably rectilinear manner, while keeping second timepiece component 30 compact.

[0085] Preferably, second watch component 30 comprises an even number of translation stages, since two translation stages arranged end to end allow the vertical deviations of hook 39 produced by each translation stage to compensate for each other. In this way, hook 39 remains at substantially the same height during movement.

[0086] The movable part 37 extends from the fourth section 59. The movable part 37 is preferably rigid. In this example, the movable part 37 has an elbow shape, which is formed by a first section 66 arranged perpendicular to the fourth section 59 and a second section 67 forming a right angle with the first section 66.

[0087] The hook 39 of the second timepiece component 30 is located at the end of the second section 67. At the free end of the first section 66, a projection 68 serves as a bearing to enable the movable part 37 to be moved.

[0088] By pressing the protrusion 68 with more or less force, the movable part 37 is moved more or less close to the stationary part 33 due to the deformation of the translation stages 51 , 52 , 53 , 54 of the spring part 35 .

[0089] In this way, the hook 39 pulls the rod 14 with more or less force in order to actuate the adjustment means for adjusting the stiffness of the flexible element 5 .

[0090] The direction of displacement of movable portion 39 of second timepiece part 30 and of stem 14 is substantially orthogonal to that of stem 14 .

[0091] Furthermore, the rod 14 is preferably movable in the hook 39 so that the rod 14 can slide when the rod 14 is angularly displaced. To this end, the rod 14 comprises a free end 15 cooperating with the hook 39.

[0092] For example, in order to be able to adjust the runout of regulating organ 1 , stud holder 31 must be able to rotate. Balance spring 25 thus rotates together with stud holder 31 , and free end 15 of stem 14 slides in hook 39 .

[0093] By means of such an actuation system 20, the yaw can be adjusted without changing the position of the second horological component 30 relative to the movement plate.Whatever the position of the lever 14 relative to the second horological component 30, the mechanical link between the second horological component 30 and the lever 14 is maintained.

[0094] Such an actuation system 20 thus enables the runout and the runout to be adjusted independently of one another, while maintaining a constant predetermined position of the second timepiece component in the movement, for example relative to the plate and balance cock 22 .

[0095] Actuation system 20 also comprises adjustment means cooperating with second horological part 30 so as to be able to displace movable portion 37 of second horological part 30 .

[0096] like Figures 7 to 10 As shown, the adjustment device comprises a pivoting lever 45 arranged to displace the movable part 37 of the second horological part 30. The lever 45 is preferably arranged in a plane substantially perpendicular to the plane of the second horological part 30 and is in contact with the projection 68 of the movable part 37.

[0097] The control lever 45 has a pivot arm 69 and a support arm 71 which is connected to a hub 72 of the pivoting control lever 45 .

[0098] The support arm 71 cooperates with the movable part 37 of the second timepiece component 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 a greater or lesser extent to move it. Thus, the hook 39 pulls the rod 14 of the balance spring 25 to a greater or lesser extent. The control lever 45 is configured to pivot in a plane substantially perpendicular to the plane of the second timepiece component 30.

[0099] Control lever 45 is configured to be mounted on the plate of the movement via a hub 72 rotatable about a screw 73 mounted on the plate.

[0100] Thus, by rotating control lever 45 about screw 73 , movable portion 37 is moved towards or away from stationary portion 33 , thereby changing the position of lever 14 , due to the deformation, to a greater or lesser extent, of spring portion 35 of second timepiece part 30 .

[0101] The adjustment device also comprises a control screw 70 which is mechanically connected to the pivot arm 69 in order to control the pivoting of the control lever 45. The axis of the control screw 70 is arranged in the plane of the control lever 45 in the direction of the pivot arm 69.

[0102] Thus, by tightening or loosening control screw 70 , control lever 45 and second timepiece part 30 are actuated so as to move hook 39 and therefore lever 14 of prestressing device 6 .

[0103] The restoring force of the spring portion 35 of the second timepiece part 30 pushes the control lever 45 against the control screw 70. In this way, the pivoting arm 69 of the control lever 45 is held against the control screw 70.

[0104] exist Fig. 9 In the embodiment, the control screw 70, the control lever 45, the movable part 37 of the second timepiece component 30 and the rod 15 are all in a first position, in which the hook 39 slightly pulls the rod 15. The dashed lines show that the control lever 45, the movable part 37 of the second timepiece component 30 and the rod 15 are in the same position as the first position. Fig.10 The corresponding second position.

[0105] exist Fig.10 In the embodiment, the control screw 70, the control rod 45, the movable part 37 of the second watch component 30 and the rod 15 are all in the second position, in which the pulling force of the hook 39 on the rod 15 is greater than Fig. 9 Medium is bigger.

[0106] In the second position, control screw 70 pushes pivot arm 69 of control lever 45 so that support arm 71 in contact with projection 68 in turn pushes movable part 37 of second timepiece component 30 towards stationary part 33 by deformation of spring portion 35. In this way, hook 39 pulls on rod 14, which is displaced eccentrically.

[0107] In this deformed configuration of the spring portion 35 , the flexible blades of the first and third translation stages 51 , 53 deform in the same first direction, while the flexible blades of the second and fourth translation stages 52 , 54 deform in the same second direction, which is opposite to the first direction.

[0108] The assembly device also comprises a spring 74 to press the second timepiece component 30 against the first timepiece component 22 so that the second timepiece component 30 does not come off.

[0109] Spring 74 exerts a retaining force on second timepiece part 30 , which retaining force is substantially orthogonal to the contact plane of first timepiece part 22 with second timepiece part 30 .

[0110] The spring 74 is arranged around the screw 73 and clamps the screw 73. The spring 74 is U-shaped around the screw 73. In this example, one leg of the U-shape extends from the stationary part 33 of the second timepiece component 30 to which it is attached.

[0111] It goes without saying that the present invention is not limited to the embodiments of the speed regulating mechanism described with reference to the accompanying drawings and alternatives may be considered without departing from the scope of the present invention.
