Description

Technical Field

[0001] The invention relates to the field of timepiece movements comprising a mechanism provided with means for variably adjusting the inclination. Background Art

[0002] Most mechanical watches today are equipped with mechanisms that are either purely decorative or at least partially movable to perform specific display functions, or a combination of these features.

[0003] An at least partially movable mechanism is, for example, a display device provided with a hand, a movable automatic mechanism, a moon phase or a movable decorative element, which can be actuated by the drive of the movement.

[0004] More specifically, the at least partially movable mechanism contains the regulating organ, which includes a sprung balance and a Swiss lever escapement. The sprung balance forms the time base of the watch. It is also known as the resonator.

[0005] The escapement has two main functions:

[0006] -Maintain the reciprocating motion of the resonator;

[0007] -Count the number of these back and forth movements.

[0008] To create a mechanical resonator, an inertial mass, a guide, and an elastic return element are required. Conventionally, a hairspring serves as the elastic return element for the inertial mass, which is formed, for example, by a balance wheel. This balance wheel is guided in rotation by a pivot rotating in a sliding jewel bearing.

[0009] To reduce the adverse effects of gravity on the movement of the regulating organ, there are complex structures such as the tourbillon or carrousel, which cause the regulating organ to rotate about an axis. These complex structures also have a special aesthetic appeal, making the timepiece very attractive.

[0010] For aesthetic reasons, in particular to facilitate viewing for the user, some adjustment mechanisms are tilted on the main plate. In some models, the adjustment mechanism is even tilted along multiple axes.

[0011] Generally speaking, however, the inclination is determined during the construction and assembly of the regulating organ on the movement and cannot be modified during use. Summary of the Invention

[0012] The present invention aims to overcome the above-mentioned drawbacks and aims to provide a timepiece movement comprising a mechanism / component capable of tilting at an adjustable angle of inclination.

[0013] To this end, the invention relates to a timepiece movement comprising a mainplate extending substantially in a first plane, configured to support other components of the timepiece movement, in particular a mechanism extending at least partially along a second plane.

[0014] It is noteworthy that the watch movement includes a variable adjustment device for variably adjusting the inclination of the mechanism relative to the main plate, and the variable adjustment device for variably adjusting the inclination of the mechanism relative to the main plate includes an inclined bridge plate on which the mechanism is mounted, and the inclined bridge plate is inclined relative to the main plate so that the second plane forms an angle with the first plane of the main plate with a variable value.

[0015] In this way, the mechanism can be tilted relative to the main plate in a preferred position due to the tilting bridge. Moreover, the degree of inclination can be modified as desired according to the wearer's wishes.

[0016] Thanks to the invention, the mechanism is no longer fixed in a predetermined position or in a timepiece movement. Depending on the orientation of the timepiece, the mechanism can be tilted in a preferred position, in particular for better viewing.

[0017] According to a particular embodiment of the invention, the inclined bridge comprises a main longitudinal platform on which the mechanism is mounted.

[0018] According to a particular embodiment of the invention, the inclined bridge comprises a secondary platform arranged below the main platform so as to arrange the at least one balance staff between the two platforms.

[0019] According to a particular embodiment of the invention, the inclined bridge is mounted so that it can rotate about an axis of rotation passing through the mechanism.

[0020] According to a particular embodiment of the invention, the tilting bridge comprises two external pivots arranged symmetrically on either side of the mechanism, said two external pivots being arranged along the axis of rotation of the tilting bridge.

[0021] According to a particular embodiment of the invention, each of said external pivots cooperates with a bearing of the main plate, said two external pivots being able to rotate within each bearing.

[0022] According to a particular embodiment of the invention, the variable adjustment device comprises a wheel mounted so that it is integral with the tilting bridge, actuation of which wheel produces the tilting of the tilting bridge.

[0023] According to a particular embodiment of the invention, the wheel comprises an inclined toothing arranged around one of said external pivots, extending parallel to the axis of rotation of the inclined bridge.

[0024] According to a particular embodiment of the invention, the timepiece movement comprises actuating means for actuating the inclination of the inclined bridge.

[0025] According to a particular embodiment of the invention, this inclined toothing cooperates with an actuating device meshing with said wheel so as to cause the inclined bridge to rotate about its axis of rotation.

[0026] According to a particular embodiment of the invention, the actuating means comprise a gear train provided with a final wheel meshing with the inclined toothing of said wheel.

[0027] According to a particular embodiment of the invention, the actuating means comprise a lever which actuates the gear train by its rotation, the lever being actuable from outside the main plate.

[0028] According to a specific embodiment of the present invention, the tilt angle of the mechanism relative to the main board is in the range of 0° to 45°.

[0029] According to a particular embodiment of the invention, the mechanism is a regulating mechanism provided with an inertial mass, a guide and elastic return element for the inertial mass configured to cause it to oscillate, and an escapement cooperating with the inertial mass.

[0030] According to a particular embodiment of the invention, the variable adjustment device for variably adjusting the inclination of the regulating organ comprises a carriage in which the inertial mass, the guide, the elastic return element and the escapement are arranged, the carriage being mounted on the inclined bridge.

[0031] According to a particular embodiment of the invention, the carriage is rotatable relative to the inclined bridge, wherein the regulating organ is of the tourbillon or carrousel type.

[0032] According to a particular embodiment of the invention, the bracket is immobile relative to the inclined bridge.

[0033] According to a particular embodiment of the invention, the mechanism is an automatic device or a decorative part of a timepiece movement.

[0034] The invention also relates to a timepiece comprising such a timepiece movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The invention relates to a timepiece movement comprising a main plate extending substantially in a first plane, the main plate being configured to support components of the timepiece movement. The timepiece movement comprises a drive device comprising a barrel, a gear system and a mechanism.

[0065] In the embodiment shown in the figures, the mechanism is a regulating mechanism provided with an inertial mass, a guide and elastic return element for the inertial mass configured to cause the inertial mass to oscillate substantially in a second plane, and an escapement cooperating with the inertial mass.

[0066] In the following description, a drive device refers to a component for supplying and transmitting the energy required to operate the adjustment mechanism, an adjustment device refers to an element for tilting and driving the adjustment mechanism while allowing energy to be transmitted, and an actuator device refers to a part arranged to change the inclination of the adjustment mechanism, for example by a user.

[0067] Figures 1 to 13 Specifically shown is a carrousel type regulating mechanism 1. The present invention does not specifically relate to the inherent characteristics and operation of a carrousel which are well known to those skilled in the art.

[0068] Carrousel 1 comprises a carrousel carriage 2, in which a mechanical resonator having an inertial mass 3, a guide and an elastic return element 4, and a Swiss lever escapement 5 are arranged. Carrousel carriage 2 is mounted so that it rotates about an axis of rotation by means of a ball bearing 6 arranged between carrousel carriage 2 and an inclined bridge 7 on which carrousel carriage 2 is mounted.

[0069] The carrousel carriage 2 comprises an upper support 8 and a lower support 9, which are assembled by screws 11 inserted into pillars 12, of which there are three pillars 12. A mechanical resonator having an inertial mass, a guide and an elastic return element, and an escapement mechanism are suspended between the upper support 8 and the lower support 9. According to a non-limiting alternative embodiment, the upper support 8 is a circular wheel, in which case three branches 13 are provided connected to a central hub 15. In this case, the lower support 9 comprises three arms 14 extending from a central joint, which arms 14 connect three eccentric pillars 12 to the central joint. The three pillars 12 are angularly distributed around the periphery of the carrousel carriage 2 so as to connect the circular wheel to each arm 14.

[0070] The inertial mass 3 is an annular balance wheel arranged on a first axial balance shaft 16 provided in the middle of the carrousel carriage 2. The first axial balance shaft 16 is substantially perpendicular to the second plane of the inertial mass.

[0071] The balance wheel is arranged in the upper part of the carrousel carriage 2 so that it is visible from the outside. Figure 3 and 4 As shown, the balance wheel is configured to be able to perform a rotational oscillating motion around a first axial balance staff 16 at a predetermined frequency within the carrousel bracket 2 .

[0072] To actuate the mechanical resonator, a second axial balance staff 17 is provided below the first axial balance staff 16 and approximately colinear with the first axial balance staff 16. The second axial balance staff 17 extends partially under the carrousel carriage 2 and the inclined bridge 7. A first axial pinion 18, centrally integral with the second axial balance staff 17, is coaxial with the balance wheel and is arranged below the carrousel carriage 2.

[0073] An intermediate wheel 19 is integrated with the second axial balance staff 17, located below the balance wheel in the carrousel carriage 2. It meshes with an escapement pinion 21, located on a third radial balance staff 22, which is generally parallel to the axial balance staffs 16 and 17. This third radial balance staff 22 is located in the carrousel carriage 2. It also holds an escapement wheel 25, which is positioned above the escapement pinion 21. This escapement wheel 25 engages a Swiss lever 26, positioned vertically between the first axial balance staff 16 and the outer periphery of the escapement wheel 25. Lever 26 comprises an elongated body with a prong at one end. The prong is configured to engage a pin on the first axial balance staff 16, which is coupled to the movement of the balance wheel. The second end of lever 26 includes a pallet stone, which is configured to engage with the escapement wheel 25, thereby alternately blocking the escapement wheel 25's rotation and allowing it to rotate gradually. The lever 26 is carried by a fourth radial balance staff 27 arranged in the carrousel carriage 2 between the first axial balance staff 16 and the third radial balance staff 22 .

[0074] The tilting bridge 7 carries the regulating mechanism, and the second axial balance staff 17 passes through the tilting bridge 7. A first axial pinion 18 is arranged below the tilting bridge 7.

[0075] Turning first axial pinion 18 actuates the movement of escape wheel 25 , lever 26 and balance via intermediate wheel 19 and escape pinion 21 which rotate third radial balance staff 22 .

[0076] The carrousel 1 further comprises a radial transmission wheel 29 arranged below the carrousel carrier 2, which meshes with the first axial pinion 18. The radial transmission wheel 29 is carried by a fifth radial balance shaft 28 arranged below the carrousel carrier 2. The actuation of the radial transmission wheel 29 causes the first axial pinion 18 to rotate.

[0077] According to the present invention, the watch movement comprises a variable adjustment device 30 for variably adjusting the inclination of the adjustment mechanism relative to the main plate so that the second plane of the inertial mass member forms an angle with a variable value with the first plane of the main plate, such as Figure 1 and 2 shown.

[0078] Therefore, the carrousel 1 can be displaced between a position where the second plane of the inertial mass is substantially parallel to the first plane of the main plate and an inclined position where the second plane of the inertial mass forms an angle with the first plane of the main plate.

[0079] The inclination angle can be selected using the inclination variable adjustment device 30. Preferably, the variable adjustment device 30 modifies the inclination angle of the regulating mechanism relative to the main plate within a range of 0° to 45°. Thus, at 0°, the balance wheel of the regulating mechanism is preferably parallel to the first plane of the main plate, while at 45°, the regulating mechanism is tilted relative to the first plane of the main plate. With the help of the variable adjustment device 30, this angle can take any value between the two extremes. Figure 1 In , the minimum angle is approximately 0°, and in Figure 2 In the embodiment, the maximum angle is 30°. In the present embodiment, the maximum angle is 30°.

[0080] To achieve this adjustable inclination, the variable adjustment mechanism 30 includes a first transmission gear 31 disposed on the main plate. A drive mechanism allows the first transmission gear 31 to rotate relative to the main plate. The first transmission gear 31 is tilted relative to the main plate. The first transmission gear 31 includes a generally spherical toothed portion 32 configured to mesh with the radial transmission wheel 29 of the regulating mechanism to actuate the escapement and balance wheel.

[0081] The first transmission gear 31 has an hourglass shape with concave cylindrical symmetry about its longitudinal axis of symmetry. The outer periphery of the first transmission gear 31 curves inward. Therefore, the diameter and circumference at the center of the transmission gear are smaller than the nominal diameter and circumference at the ends of the first transmission gear 31. Preferably, the nominal diameter and circumference at both ends of the first transmission gear 31 are the same. The length of the first transmission gear 31 is preferably greater than its nominal diameter.

[0082] The concave outer peripheral surface allows the radial transmission wheel 29 to mesh with the first transmission gear 31 regardless of the inclination of the carrousel 1. Therefore, the generally spherical tooth portion 32 has a spherical shape. The curvature of the concave outer peripheral surface is selected to match the radius and inclination of the radial transmission wheel 29. Therefore, regardless of the inclination of the carrousel, the first transmission gear 31 meshes with the radial transmission wheel 29. Each tooth is curved toward the interior of the first transmission gear 31 and has the same radius of curvature. Regardless of the orientation of the radial transmission wheel 29 and the first transmission gear 31, this concave spherical cutter / tooth portion promotes engagement with the radial transmission wheel 29.

[0083] The first transmission gear 31 also includes straight-cut teeth / a straight tooth section. Thus, the first transmission gear 31 has a double-cut tooth section, which is a combination of concave spherical cut teeth and straight-cut teeth. Straight-cut teeth mean that each tooth has the same profile throughout its entire height. Double-cut teeth are achieved by forming a first concave spherical cut tooth, so as to obtain teeth that curve toward the interior of the first transmission gear 31. The resulting teeth have a variable profile over the height of the tooth, with each tooth being thicker at the ends. A second straight-cut tooth is then formed, particularly at the thick end of the tooth, to obtain teeth with a roughly uniform profile at the ends.

[0084] Thus, the first transmission gear 31 comprises a region 23 whose teeth are straight teeth. The region 23 is arranged around the entire circumference of the first transmission gear 31 above the substantially spherical toothing 32. This region 23 facilitates coupling with the transmission wheel 20.

[0085] The transmission wheel 20 comprises an inclined toothing 83 in order to cooperate with the region 23 of the first transmission gear 31 , which is inclined relative to the axis of the transmission wheel 20 .

[0086] As a result, the transmission wheel 20 does not change its plane, so that its inclined toothing 83 effectively cooperates with the region 23 of the first transmission gear 31 which is itself inclined.

[0087] The radial transmission wheel 29 has an outer peripheral toothing configured to mate with the spur teeth of the region 23 of the first transmission gear 31. To improve meshing with the first transmission gear 31, the radial transmission wheel 29 includes an outer peripheral toothing 34 that is tilted relative to the plane of the radial transmission wheel 29. The diameter and circumference of the radial transmission wheel 29 at its base are smaller than the diameter and circumference of the radial transmission wheel 29 at its upper portion. The diameter and circumference widen from the base to the upper portion of the wheel.

[0088] The radial transmission wheel 29 can be tilted between a minimum tilt position and a maximum tilt position. In the minimum tilt position, the outer peripheral gear ring 34 of the radial transmission wheel 29 meshes with the substantially spherical teeth 32 of the first transmission gear 31 at the lower end thereof, while in the maximum tilt position, the outer peripheral gear ring 34 of the radial transmission wheel 29 meshes with the substantially spherical teeth 32 of the first transmission gear 31 at the upper end thereof.

[0089] For carrousel 1, the variable adjustment device 30 includes a second transmission gear 35 arranged on the main plate, which is capable of rotating relative to the main plate. The second transmission gear 35 is configured to constrain the carrousel bracket 2 of the adjustment mechanism via the outer ring gear 36 of the carrousel bracket 2. The outer ring gear 36 is arranged on the outer periphery of the upper support 8, and its teeth extend radially away from the carrousel bracket 2. Therefore, the second transmission gear 35 constrains the rotational movement of the carrousel bracket 2 so that the carrousel bracket 2 rotates around its rotation axis at a predetermined speed, thereby preventing it from rotating too fast. The rotational movement of the second transmission gear 35 around its rotation axis itself is constrained by the drive device of the movement.

[0090] The second transmission gear 35 is preferably similar or even identical to the first transmission gear 31, whereby the second transmission gear 35 further comprises a substantially spherical tooth portion 37 and straight-cut teeth 70. The straight-cut teeth 70 are arranged below the substantially spherical tooth portion 37.

[0091] exist Figure 5 In Figure 1, the first transmission gear 31 or the second transmission gear 35 is cut in two different ways. Starting from the transmission gear blank, the first cut is made to produce a roughly spherical tooth section 32, 37. The second straight cut is made to produce the final transmission gear 31, 35 shown on the right. The straight cut results in teeth with the same profile across the entire height of the straight cut area. Thus, the straight cut forms areas 23, 70 with straight teeth.

[0092] Two transmission gears 31 and 35 are arranged on either side of the carrousel bracket 2. The first transmission gear 31 is tilted on the main board, while the second transmission gear 35 is approximately perpendicular to the main board. The second transmission gear 35 is arranged at a higher height than the first transmission gear 31. More specifically, the second transmission gear 35 mates with a gear on the upper support member 8 provided in the upper portion of the carrousel 2, while the first transmission gear 31 mates with a radial transmission wheel 29 provided in the lower portion of the carrousel bracket 2.

[0093] In the upright position, the upper support member 8 is engaged with the top of the second transmission gear 35, and the radial transmission wheel 29 is engaged with the bottom of the first transmission gear 31. In the tilted position, the upper support member 8 is engaged with the bottom of the second transmission gear 31, and the radial transmission wheel 29 is engaged with the top of the first transmission gear 31.

[0094] In the carrousel 1, the two transmission gears 31 and 35 rotate simultaneously, and the first transmission gear 31 is rotated by the driving device via the gear train 98, as shown in FIG. Figures 6 to 9 As shown, the second transmission gear 35 is driven by the movement of the carrousel bracket 2 and is constrained by the driving device.

[0095] To this end, the drive comprises a crown 38 with an internal toothing 24, such as Figures 6 to 9 As shown. Crown 38 is arranged around carrousel carriage 2 so that it constrains second transmission gear 35 as it rotates, rotating around carrousel carriage 2. Thus, by constraining second transmission gear 35, crown 38 allows the movement of carrousel carriage 2 to be controlled, while also allowing the escapement and balance wheel to be actuated. Crown 38 meshes with straight-cut teeth 70 of second transmission gear 35. The crown also includes an outer toothed ring 92 configured to mesh with transmission wheel 93 of gear train 98.

[0096] The drive unit is included in Figure 11 The transmission wheel 20 of the first transmission gear 31 is shown in FIG. 1 , which is further actuated by a gear train 98 .

[0097] In addition, the variable adjustment device 30 for variably adjusting the inclination of the adjustment mechanism includes a tilted bridge plate 7, on which the carrousel bracket 2 is mounted, and a ball bearing 6 is arranged between the carrousel bracket 2 and the tilted bridge plate 7. The bridge plate can be tilted to allow the adjustment mechanism to be tilted. The tilted bridge plate 7 is arranged below the carrousel bracket 2, above the first axial pinion 18 and the radial transmission wheel 29. The tilted bridge plate 7 is installed so that it can rotate around the rotation axis D1 passing through the carrousel bracket 2, and the rotation axis D1 is parallel to the tilted bridge plate 7, and preferably parallel to the plane of the main plate. The tilted bridge plate 7 includes two external pivots 42, 43 symmetrically arranged on both sides of the carrousel bracket 2, each pivot 42, 43 extending from a pillar arranged at the end of the tilted bridge plate 7.

[0098] Pivots 42 and 43 each engage bearings 39 and 41 on the main plate. Pivots 42 and 43 are arranged along the rotation axis D1 of the tilting bridge 7. Each bearing 39 and 41 includes a hole for receiving a pivot 42 and 43. Both pivots 42 and 43 are rotatable within each bearing 39 and 41. Thus, the tilting bridge 7 can rotate about the rotation axis D1 using the pivots 42 and 43 and the bearings 39 and 41.

[0099] Variable adjustment mechanism 30 includes a gear 44 mounted integrally with tilting bridge 7. Actuation of gear 44 causes tilting bridge 7 to tilt. Gear 44 includes a tilting toothed ring 45 disposed about one of pivots 42 and 43. Tilt toothed ring 45 extends parallel to axis of rotation D1 of tilting bridge 7. Tilt toothed ring 45 cooperates with an actuating mechanism. The actuating mechanism meshes with gear 44, causing tilting bridge 7 to rotate about axis of rotation D1.

[0100] Figures 6 to 8 The tilting actuation device is shown, comprising a lever 46 and a gear train 47. Lever 46 is actuated, for example, by a crown (not shown). Lever 46 is equipped with a pinion 48 comprising a peripheral toothing 49, which meshes with a transmission gear 51 that actuates gear train 47. Gear train 47 comprises a series of transmission wheels and pinions, which are actuated by transmission gear 51 to transmit the rotational force received by lever 46 to tilting bridge 7. The final gear 52 of the gear train meshes with the toothing 45 of gear 44, which is integrally mounted on tilting bridge 7. Thus, by rotating lever 46 about its axis, the gear train is actuated until gear 44 is engaged, which tilts tilting bridge 7 at a selected angle.

[0101] Other embodiments of the actuation means are conceivable, for example positioning in a jump.

[0102] Figure 10Shown is a main plate 33 provided with a carrousel and an actuating device. A rod 46 extends beyond the main plate so that the tilt of the adjustment mechanism can be actuated and modified. The main plate 33 comprises a recess in which the adjustment mechanism is arranged.

[0103] Figure 11 The assembly comprising the first transmission gear 31 and the radial transmission wheel 29 is shown. The radial transmission wheel 29 and the transmission gear 31 cooperate in such a way that the radial transmission wheel 29 can be tilted while maintaining an equal amount of meshing between the transmission gears. This means that within a defined operating range between minimum and maximum tilt, the ability to transmit rotational motion from one to the other is the same regardless of the tilt of the gears.

[0104] exist Figure 12 and 13 In the present invention, inclined bridge 7 comprises a longitudinal main platform 53, at the ends of which are provided the supports of pivots 42, 43. Platform 53 comprises a central hole allowing the passage of second axial balance staff 17. The main platform comprises an eccentric bearing 95 for receiving fifth radial balance staff 28.

[0105] Tilting bridge 7 includes a secondary platform 54 arranged below main platform 53. Secondary platform 54 includes a first bearing 50 arranged to receive second axial balance staff 17. First bearing 50 is aligned with the central aperture of main platform 53. Secondary platform 54 includes a second eccentric bearing 94 for receiving fifth radial balance staff 28, which is aligned with the eccentric bearing of main platform 53. Thus, fifth radial balance staff 28 is retained between main platform 53 and secondary platform 54.

[0106] A ball bearing is fitted into the central hole and held in a recess arranged between the main platform 53 and the sub-platform 54 .

[0107] exist Figures 14 to 22 In the second embodiment of the invention shown, the regulating organ is a tourbillon 10. The invention does not specifically concern the inherent characteristics and operation of a tourbillon, which are well known to those skilled in the art.

[0108] Tourbillon 10 comprises a movable carriage 55 in which an inertial mass 56 , a guide, an elastic return element 68 and an escapement 69 are arranged.

[0109] The tourbillon carrier 55 is mounted so that it rotates about an axis of rotation by means of a ball bearing 60 arranged between the tourbillon carrier 55 and an inclined bridge 57 on which the tourbillon carrier 55 is mounted.

[0110] The tourbillon carriage 55 comprises an upper support 58 and a lower support 59, assembled by screws inserted into two posts 61. A mechanical resonator, including an inertial mass 56, a guide, and an elastic return element, and an escapement mechanism are suspended between the upper and lower supports 58 and 59. Each of the upper and lower supports 58 and 59 resembles a cross-shaped structure with two branches 63 and 64 at an intersection 65. The two supports 58 and 59 are arranged parallel to each other, one above the other. Two posts 61 and 62 connect the two supports 58 and 59, each connecting the end of a branch 63 of one support 58 to the end of a corresponding branch of the other support 58 or 59. The ends of the other branches each support a bearing for the tourbillon's balance staff: one for the inertial mass and the other for the escape wheel. The posts 61 and 62 are assembled to the two supports 58 and 59 via screws 66.

[0111] exist Figure 16 In the embodiment of the present invention, the inertial mass 56 is an annular balance wheel arranged on a first radial balance shaft 67, which is arranged radially parallel to the rotational balance axis of the tourbillon carrier 55. The balance wheel is eccentric and arranged in the middle of the tourbillon carrier 55. The balance wheel is configured to perform a rotational oscillatory motion around the first radial balance shaft 67 at a predetermined frequency within the tourbillon carrier 55.

[0112] Arranged in the tourbillon carriage 55 is a second radial balance staff 72, which carries an escape wheel 73 positioned above an escape pinion 74, also carried by the second radial balance staff 72. The second radial balance staff 72 is parallel to the axis of rotation of the tourbillon carriage 55 and to the first radial balance staff 67. The escape pinion 74 projects eccentrically below the tourbillon carriage 55.

[0113] An escape wheel 73 is positioned in the upper portion of the tourbillon carriage 55 so that it is visible from the outside. It engages a Swiss lever 75, positioned vertically between the first radial balance staff 67 and the periphery of the escape wheel 73. Lever 75 comprises an elongated body with a prong at a first end, configured to engage a pin of the first radial balance staff 67, which is associated with the movement of the balance wheel. The second end of the lever includes two pallet stones that engage with the escape wheel 73, alternatingly blocking its rotation and allowing it to rotate gradually. Lever 75 is carried by a third radial balance staff 76, positioned in the tourbillon carriage 55, between the first radial balance staff 67 and the second radial balance staff 72.

[0114] A seconds wheel 71 is positioned between the tilting bridge 57 and the tourbillon carriage 55, axially below the tourbillon carriage 55. This wheel 71 does not rotate with the tourbillon carriage 55 but is integral with the tilting bridge 57. It meshes with an escapement pinion 74 mounted on a second radial balance staff 72. The wheel 71 is movable relative to the main plate along with the tilting bridge 57.

[0115] Thus, by rotating tourbillon carriage 55 about its axis of rotation, seconds wheel 71 rotates escapement pinion 74 , thereby actuating the movement of escapement wheel 73 , lever 75 and balance wheel.

[0116] According to the present invention, the watch movement includes a variable adjustment device 40 for variably adjusting the inclination of the tourbillon 10 relative to the main plate so that the second plane of the inertial mass member and the first plane of the main plate form an angle with a variable value, such as Figure 14 and 15 Thus, tourbillon 10 is displaceable between a vertical position in which the second plane of the inertial mass is substantially parallel to the first plane of the main plate and an inclined position in which the second plane of the inertial mass forms an angle with the first plane of the main plate.

[0117] This inclination angle can be modified by a variable inclination adjustment device 40. The variable adjustment device 40 allows the inclination angle of the regulating mechanism relative to the main plate to be adjusted within a range of 0° to 90°. Thus, at 0°, the balance wheel of the regulating mechanism is parallel to the first plane of the main plate, while at 90°, the regulating mechanism is approximately perpendicular to the main plate. Preferably, the inclination angle of the regulating mechanism relative to the first plane of the main plate ranges from 0° to 45°. With the help of the variable adjustment device 40, this angle can be adjusted to any value between these two extremes.

[0118] exist Figure 14 In , the minimum angle is approximately 0°, and in Figure 15 In the embodiment, the maximum angle is 30°. In the present embodiment, the maximum angle is 30°.

[0119] Variable adjustment device 40 comprises a transmission gear 80 arranged on the main plate, rotatable relative to the main plate due to drive means, transmission gear 80 comprising a substantially spherical toothing 81 configured to mesh with tourbillon carriage 55 to actuate it.

[0120] Tourbillon carriage 55 comprises a peripheral toothing 77 arranged on a lower support 59. Lower support 59 comprises an outer ring 82 carrying peripheral toothing 77. Thus, by engaging outer ring 82, tourbillon carriage 55 rotates about its axis.

[0121] The transmission gear 80 is similar to or even identical to that described in Carrousel. It has a cylindrical shape, and the teeth 81 on its concave outer peripheral surface are generally spherical, so as to allow the outer peripheral toothing 77 of the outer ring 82 to mesh with the transmission gear 80 regardless of the inclination of the tourbillon 10.

[0122] For example, the generally spherical teeth 81 of the transmission gear 80 are double-cut, a combination of concave spherical and straight-cut teeth. The concave spherical teeth facilitate engagement with the tourbillon carriage 55 regardless of the orientation of the tourbillon carriage 55 relative to the transmission gear 80. Straight-cut teeth mean that the width of the teeth of the transmission gear is approximately equal across the straight-cut area. Therefore, the transmission gear 80 includes a region 90 with straight teeth to facilitate engagement with the transmission wheel.

[0123] Furthermore, the outer peripheral gear ring 77 of the outer ring 82 is preferably inclined relative to the plane of the outer ring 82 so as to cooperate with the transmission gear 80 .

[0124] Unlike the carrousel of the first embodiment, the variable adjustment mechanism 40 includes a single transmission gear 80 that drives only the tourbillon carriage 55 of the tourbillon 10 to actuate the escapement. The escapement pinion 74 is actuated by the movement of the tourbillon carriage 55 and the stress of the fixed gear 71. In other words, the escapement is arranged in series with the tourbillon carriage 55 relative to the driving mechanism.

[0125] A device similar to a carrousel is used to drive the transmission gear 80. For example, the variable adjustment device 40 includes a transmission wheel of a first transmission gear actuated by a gear train. Alternatively, a crown similar to a second transmission gear actuated by a carrousel can be used to actuate the transmission gear of the tourbillon.

[0126] Figure 21 A timepiece 84 is shown provided with a case 86 and a dial 85 on which the hands move. The timepiece comprises a recess for the tourbillon 10, the dial 85 being perforated to allow viewing of the tilted tourbillon 10.

[0127] The variable adjustment device 40 for variably adjusting the inclination of the tourbillon 10 comprises an inclined bridge 57 (at Figure 22 The tourbillon carriage 55 is mounted on a tilting bridge 57, with a ball bearing 60 disposed between the tourbillon carriage 55 and the tilting bridge 57. The tilting bridge 57 can be tilted to select the inclination of the tourbillon 10. The tilting bridge 57 is disposed below the carriage, with a fixed seconds wheel 71 disposed between the tilting bridge 57 and the tourbillon carriage 55.

[0128] Tilting bridge 57 is mounted so that it can rotate about an axis of rotation D2 passing through tourbillon carriage 55, parallel to it and preferably parallel to the first plane of the mainplate. Tilting bridge 57 comprises a longitudinal main platform 96 with a central aperture 89 and struts at the ends of this platform 96. Each strut comprises an external pivot 87, 88, arranged on either side of tourbillon carriage 55 along axis of rotation D2 and cooperating with bearings (not shown) on the mainplate. A ball bearing 60 is mounted in central aperture 89, or preferably in seconds wheel 71.

[0129] Other features may be identical to those of the Carrousel bridge. The variable adjustment device 40 comprises, for example, a wheel 91 mounted integrally with the tilting bridge 57, the wheel 91 being provided with tilting teeth, the actuation of which causes the tilting bridge 57 to tilt.

[0130] The tilting actuating means are identical to those described with respect to the embodiment of the carrousel mounted integrally with the tilting bridge.

[0131] exist Figures 23 to 28 In the third embodiment of the present invention shown, the adjustment mechanism is a conventional adjustment mechanism 100 that can be tilted as needed. The present invention does not specifically relate to the inherent features and operation of conventional adjustment mechanisms that are well known to those skilled in the art.

[0132] The conventional regulating mechanism 100 comprises an inertial mass member 103 , a guide member, an elastic reset element and an escapement mechanism.

[0133] exist Figures 23 to 28 In the embodiment, a conventional regulating mechanism 100 comprises a conventional regulating mechanism carriage 102, inside which are arranged a mechanical resonator 103 having an inertial mass, a guide and an elastic return element 104, and a Swiss lever 126 escapement 105. The conventional regulating mechanism carriage 102 is mounted integrally with an inclined bridge 107.

[0134] The conventional regulating mechanism carriage 102 comprises an upper support 108 and a lower support 109, assembled by screws 111 inserted into posts 112, of which there are three. A mechanical resonator, including an inertial mass 103, a guide, and an elastic return element, as well as an escapement, are suspended between the upper and lower supports 108, 109. The upper support 108 is a ring with three branches 113 connected to a central hub. The lower support 109 includes three arms 114 extending from a central joint, connecting three eccentric posts 112 to the central joint. The three posts 112 are angularly distributed around the periphery of the conventional regulating mechanism carriage 102, so as to connect a wheel to each arm 114.

[0135] exist Figure 23In the conventional regulating mechanism, the inertial mass 103 is an annular balance wheel disposed on a first axial balance shaft 116, which is disposed in the middle of the conventional regulating mechanism carrier 102. The balance wheel is disposed in the upper portion of the conventional regulating mechanism carrier 102 so that it is visible from the outside. The balance wheel is configured to perform a rotational oscillatory motion about the first axial balance shaft 116 at a predetermined frequency within the conventional regulating mechanism carrier 102.

[0136] To actuate the mechanical resonator, a second axial balance staff 117 is provided below the first axial balance staff 116, approximately colinear with the first axial balance staff 116. The second axial balance staff 117 extends partially below the conventional regulating mechanism carrier 102 and the inclined bridge 107. A first axial pinion 118, integral at its center with the second axial balance staff 117, is coaxial with the balance wheel and arranged below the conventional regulating mechanism carrier 102.

[0137] Intermediate wheel 119 is integral with second axial balance staff 117, located below the balance wheel in conventional regulating mechanism carrier 102. Intermediate wheel 119 meshes with an escapement pinion 121, arranged on a third radial balance staff 122, which is generally parallel to first and second axial balance staffs 116, 117. Third radial balance staff 122 is arranged in conventional regulating mechanism carrier 102. Third radial balance staff 122 also holds an escapement wheel 125, which is positioned above escapement pinion 121. Escapement wheel 125 cooperates with a Swiss lever 126, positioned vertically between first axial balance staff 116 and the outer periphery of escapement wheel 125. Lever 126 comprises an elongated body with a prong at a first end. The prong is configured to cooperate with a pin of first axial balance staff 116, which is associated with the movement of the balance wheel. The second end of lever 126 comprises two pallet stones which cooperate with escape wheel 125 to alternately block the rotation of escape wheel 125 so as to cause it to rotate step by step. Lever 126 is carried by a fourth radial balance staff 127 arranged in conventional regulating mechanism carriage 102, between first axial balance staff 116 and third radial balance staff 122.

[0138] Turning first axial pinion 118 actuates the movement of escape wheel 125 , lever 126 and balance wheel via intermediate wheel 119 and escape pinion 121 which rotate third radial balance staff 122 .

[0139] The conventional adjusting mechanism 100 further comprises a radial transmission wheel 129 disposed below the conventional adjusting mechanism bracket 102, which meshes with the first axial pinion 118. The radial transmission wheel 129 is carried by a fifth radial balance shaft 128 disposed below the conventional adjusting mechanism bracket 102. Actuation of the radial transmission wheel 129 causes the first axial pinion 118 to rotate.

[0140] According to the present invention, the timepiece movement includes a variable adjustment device 130 for variably adjusting the inclination of the regulating organ 100 relative to the main plate, such that the second plane of the rotating balance staff and the inertial mass forms a variable inclination angle with the first plane of the main plate. Thus, the regulating organ 100 can be tilted to obtain a variable inclination angle, which can be selected using the variable adjustment device 130.

[0141] Preferably, the variable adjustment device 130 modifies the inclination angle of the regulating mechanism relative to the mainplate within a range of 0° to 45°. Thus, at 0°, the regulating mechanism's balance wheel is parallel to the first plane of the mainplate, while at 45°, the regulating mechanism is tilted relative to the first plane of the mainplate. This angle can be adjusted to any value between these two extremes using the variable adjustment device 130.

[0142] exist Figure 24 In , the minimum angle is approximately 0°, and in Figure 25 In the embodiment, the maximum angle is 30°. In the present embodiment, the maximum angle is 30°.

[0143] To achieve this adjustable tilt, the variable adjustment mechanism 130 includes a transmission gear 131 disposed on the main plate. Drive means allow transmission gear 131 to rotate relative to the main plate. Transmission gear 131 includes a generally spherical toothed portion 181 configured to mesh with radial transmission wheel 129 of adjustment mechanism 100 to actuate the radial transmission wheel.

[0144] The transmission gear 131 is similar or even identical to the first transmission gear of the Carrousel. It has a cylindrical shape, and the teeth 181 on its concave outer circumference are spherical to allow the radial transmission wheel 129 to mesh with the transmission gear 131 regardless of the inclination of the conventional adjustment mechanism. This generally spherical tooth portion 181 facilitates engagement with the radial transmission wheel 129 regardless of the orientation of the radial transmission wheel 129 and the transmission gear 131.

[0145] The transmission gear 131 also includes double-cut teeth that combine concave spherical cut teeth and straight cut teeth. Straight cut teeth refer to that the width of the teeth of the transmission gear 131 is approximately equal at the height of the straight cut area.

[0146] Therefore, the transmission gear 131 comprises a region 180 with straight teeth in order to be able to cooperate with the transmission wheel.The region 180 is arranged above the concave outer peripheral surface.

[0147] Furthermore, the radial transmission wheel 129 preferably includes an outer peripheral toothing 182 that is inclined relative to the plane of the radial transmission wheel 129 so as to cooperate with the straight-cut teeth 180 of the transmission gear 131 .

[0148] The variable adjustment device 130 comprises a single transmission gear 131 which drives only the escapement. The tilt actuation means are identical to those described for the carrousel and tourbillon embodiments.

[0149] The transmission gear 131 is actuated by a drive device via a gear train 98. To this end, the drive device comprises a transmission wheel that directly actuates the transmission gear 131 via spur teeth 180, as in the case of the first transmission gear of the carrousel. Alternatively, the drive device may comprise a crown with internal teeth arranged around a conventional adjustment mechanism bracket 102 so as to be able to actuate the transmission gear 131 when the crown rotates around the conventional adjustment mechanism bracket 102, as in the case of the second transmission gear of the carrousel.

[0150] Thus, by rotating transmission gear 131 , the crown or transmission wheel produces a movement of the escapement and balance in conventional regulating mechanism carrier 102 of regulating mechanism 100 . In this embodiment of conventional regulating mechanism 100 , conventional regulating mechanism carrier 102 does not move relative to inclined bridge 107 .

[0151] The variable adjustment device 130 for variably adjusting the inclination of the adjustment mechanism 100 includes an inclined bridge 107 on which the conventional adjustment mechanism bracket 102 is mounted. The inclined bridge 107 can be tilted to select the inclination of the adjustment mechanism 100. The inclined bridge 107 is arranged below the conventional adjustment mechanism bracket 102.

[0152] The inclined bridge 107 is similar to or identical to the inclined bridge of the carrousel in the first embodiment.

[0153] The tilting bridge 107 is mounted so that it can rotate about an axis of rotation D3 that passes through the conventional regulating mechanism 102 and is parallel to the tilting bridge 107. The tilting bridge 107 comprises a longitudinal main platform 97 with a central hole and struts at its ends. Each strut comprises an external pivot 187, 188, which is arranged on either side of the conventional regulating mechanism bracket 102 along the axis of rotation D3 and cooperates with two bearings on the main plate.

[0154] The other features are the same as those of the bridge splint of Carrousel 1, wherein the inclined bridge splint 107 further comprises a secondary platform 99. The actuation device comprises a wheel 185 mounted integrally with the inclined bridge splint 107, the actuation of which causes the inclined bridge splint 107 to tilt.

[0155] The actuating device comprises a wheel 185 integrally mounted to tilting bridge 107. Actuation of this wheel 185 causes tilting bridge 107 to tilt. Wheel 185 includes a tilting toothed ring 145 disposed about one of pivots 187 and 188, extending parallel to axis of rotation D3. Tilt toothed ring 145 cooperates with the actuating device. The actuating device meshes with wheel 185, causing tilting bridge 107 to rotate about axis of rotation D3.

[0156] The tilt actuation means are identical to those described for the embodiments of Carrousel 1 and Tourbillon 10 .

[0157] It goes without saying that the present invention is not limited to the embodiments of the regulating organ described with reference to the accompanying drawings, and alternatives are contemplated without departing from the scope of the invention. In particular, the at least partially movable mechanism may be, for example, an automatic or a movable decorative element, such as a rotating diamond or globe, or a day / night display that can be tilted to suit preference. The at least partially movable mechanism may also be a moon phase, date, power reserve indicator, or minute counter of a chronograph, or even an aperture for a concealed display, or a GMT-type display. The mechanism may also be, for example, a small seconds display made of jewels, which can be viewed from different angles thanks to a device for adjusting the mechanism's inclination. Furthermore, purely decorative elements may also be arranged on the tilting bridge, such as representations obtained by etching or thin-film deposition, or even jewels.
