Description

Technical field of the invention

[0001] The invention relates to the field of three-dimensional carousel-type regulating organs for watch movements. Technological background

[0002] Most modern mechanical watches are equipped with regulating organs including a balance wheel and hairspring, and a Swiss lever escapement mechanism. The balance wheel and hairspring form the watch's timekeeping base. It is also called a resonator.

[0003] The exhaust system, for its part, fulfills two main functions: to maintain the back-and-forth movement of the resonator; to count these back-and-forth movements.

[0004] To create a mechanical resonator, one needs an inertial mass, a guide, and an elastic restoring element. Traditionally, a spiral spring acts as the elastic restoring element for the inertial mass, such as that of a balance wheel. This balance wheel is guided in rotation by pivots that rotate in ruby ​​bearings.

[0005] To mitigate the adverse effects of gravity on the movement of the regulating organ, tourbillon or carousel complications were developed, allowing the entire regulating organ to rotate around a central axis. The regulating organ is housed in a rotating cage, which spins continuously around this axis. These complications also offer a distinctive aesthetic appeal, making the timepiece particularly attractive.

[0006] In a tourbillon, the escapement mechanism and the cage's rotation mechanism are arranged in series. Generally, the movement's drive system activates the cage's rotation, and it is the cage's rotation that drives the escapement mechanism. The escapement mechanism meshes with a fixed wheel of the movement to be set in motion.

[0007] A carousel operates differently, as the rotation of the cage and the actuation of the escapement mechanism are produced in parallel by the drive means. The two movements are independent of each other. Thus, unlike a tourbillon, the cage can rotate even if the escapement mechanism is blocked.

[0008] To prevent the cage from spinning freely when unloading the barrel, the carousel includes a retaining gear, which locks the cage if the escapement mechanism is blocked.

[0009] To further improve the accuracy of the regulating organ relative to gravity, three-dimensional vortices were developed. Such vortices comprise at least two cages rotating around at least two axes of rotation, preferably perpendicular to each other.

[0010] Generally, the rotation of the cage(s) is driven by gears connected to the drive mechanism, which mesh, for example, with an axial shaft located beneath the cage. There are also regulating devices equipped with peripheral teeth around the cage; these teeth allow the drive mechanism to drive the cage's rotation.

[0011] To allow rotation, the axial shaft is generally mounted in bearings. However, in some cases, the cage's axial shaft is mounted on a ball bearing, particularly for certain carousels.

[0012] The carousel was invented by the Danish watchmaker Bonniksen and its operation is described, for example, in patent CH 7965.

[0013] Multi-cage vortices are described in documents WO2005071498 A1 or CH711417 B1 for example.

[0014] Thus, current configurations of regulating organs of this type are quite limited, and there are few alternatives to these examples. Summary of the invention

[0015] The invention aims to remedy the aforementioned drawbacks, and seeks to provide a watch movement comprising a three-dimensional regulating organ having a new configuration.

[0016] To this end, the invention relates to a three-dimensional carousel-type regulating organ for a watch movement, the regulating organ comprising drive means equipped with a barrel and a gear train, said regulating organ comprising an inertial mass, means for elastically returning the inertial mass, an escapement mechanism, an inner cage movable in rotation about a first axis of rotation, an outer cage movable in rotation about a second axis of rotation, the inner cage being housed inside the outer cage, the inner cage carrying the inertial mass, the means for elastically returning the inertial mass and the escapement mechanism.

[0017] The regulating organ is remarkable in that it includes a first ball bearing arranged to allow the rotation of the outer cage in the clockwork movement, the first ball bearing being arranged at the periphery of the outer cage.

[0018] Thus, by having a ball bearing on the periphery of the cage, it is avoided to have to position it on the shaft below the cage, the shaft can be removed or used only for the actuation of the escapement mechanism.

[0019] Thanks to the invention, new configurations of a three-dimensional carousel can be obtained, or for example to gain in compactness, in particular by reducing the height of the regulating organ.

[0020] According to the invention, the regulating organ is a three-dimensional carousel, the drive means being configured to actuate the rotational movement of the outer cage in parallel with the rotational movement of the inner cage, a first part of the torque supplied by the drive means being transmitted to the outer cage, and a second part of the torque being transmitted to the inner cage.

[0022] According to a particular embodiment of the invention, the drive means comprise a second drive ring arranged around the second axis of rotation of the outer cage, preferably around the outer cage, the second drive ring being configured to transmit in parallel to the outer and inner cages the first and second part of the torque supplied by the drive means.

[0023] According to a particular embodiment of the invention, the rotation of the seconds driving crown also actuates the escapement mechanism in parallel with the rotations of the outer cage and the inner cage.

[0024] According to a particular embodiment of the invention, the regulating member comprises a cage-driving mobile carried by the outer cage or the inner cage, the cage-driving mobile being free to rotate relative to the outer and inner cages, the rotation of the cage-driving mobile actuating in parallel the escapement mechanism and the rotational movement of the inner cage.

[0025] According to a particular embodiment of the invention, the second driving ring meshes with the cage driving wheel.

[0026] According to a particular embodiment of the invention, the escapement mechanism comprises an escape wheel, an escape pinion and an intermediate wheel meshing with the escape pinion, the cage drive mobile meshing with the intermediate wheel of the escapement mechanism.

[0027] According to a particular embodiment of the invention, the regulating organ includes first retaining gears for the inner cage, the first retaining gears being arranged in the inner cage so as to mesh with the intermediate wheel of the escapement mechanism and a wheel attached to the outer cage, in order to prevent excessive rotational speed of the inner cage.

[0028] According to a particular embodiment of the invention, the regulating member comprises second retaining gears for the outer cage, the second retaining gears being arranged outside the outer cage, so as to mesh with the seconds driving crown and with the outer cage, in order to prevent excessive rotational speed of the outer cage.

[0029] According to a particular embodiment of the invention, the seconds driving crown comprises two sets of teeth, a first set of teeth meshing with the cage driving mobile, and a second set of teeth meshing with the second retaining gears.

[0030] According to a particular embodiment of the invention, the regulating member includes a second ball bearing arranged to allow the rotation of the second driving ring.

[0031] According to a particular embodiment of the invention, the outer cage comprises an upper annular part and a lower annular part rigidly connected to each other, the upper annular part supporting the inner cage by at least one bearing, preferably two bearings, the lower part being provided with external teeth.

[0032] According to a particular embodiment of the invention, the inner cage comprises an upper support and a lower support, the inertial mass, the elastic return means for the inertial mass and the escape mechanism being suspended between the upper support and the lower support.

Detailed description of the invention

[0037] The invention relates to a regulating organ of the tourbillon or three-dimensional carousel type and a watch movement 10 comprising such a regulating organ.

[0038] In the following description, the regulating organ is a three-dimensional carousel 1.

[0039] The clock movement 10 includes a plate (not shown in the figures), which preferably extends substantially in a plane, the plate being configured to support parts of the movement 10.

[0040] Movement 10, partly represented on the Figures 1 And 2 , also includes drive means 15 comprising a barrel 7 and a gear train 13 enabling the movement of the hands (not shown) to be actuated and the driving force supplied by the spring of the barrel 7 to the three-dimensional carousel 1.

[0041] The three-dimensional carousel 1 is a regulating organ equipped with an inertial mass 6, a guide, and an elastic return element 4 for the inertial mass 6, configured to make it oscillate substantially in a plane. The three-dimensional carousel also includes an escapement mechanism 5 cooperating with the inertial mass 6. The elastic return element 4 is, for example, a balance spring, and the inertial mass 6 is an annular balance wheel associated with the balance spring to produce an oscillatory motion. The escapement mechanism 5 is, for example, a conventional escapement mechanism comprising an escape wheel 25, a pallet fork 26, and an intermediate wheel 19. The escape wheel 25 cooperates with the pallet fork 26 to rotate intermittently, according to a predetermined frequency. The pallet fork 26 is mobile thanks to the movement of the balance wheel and the impulses of the escape wheel 25.

[0042] In the following description, the drive means 15 refer to the parts that supply and transmit the energy necessary for the operation of the three-dimensional carousel 1.

[0043] The invention does not specifically relate to the intrinsic characteristics and operation of a simple carousel, which are known to a person skilled in the art.

[0044] THE figures 1 to 8 in particular show a three-dimensional carousel 1. The three-dimensional carousel 1 includes an inner cage 2 inside which are arranged the mechanical resonator equipped with the inertial mass 6, the guide and the elastic return element 4, as well as a Swiss anchor escapement mechanism 5 26.

[0045] The inner cage 2 comprises an upper support 8 and a lower support 9 assembled to an intermediate structure 57 by screws 11 inserted into uprights 12, two for the upper support 8, and three for the lower support 9. The mechanical resonator with the inertial mass 6, the guide and the elastic return element 4 are suspended between the upper support 8 and the intermediate structure 57, while the escapement mechanism 5 is suspended between the intermediate structure 57 and the lower support 9.

[0046] The lower support 9 includes a frame 14 with several segments 23 connected to each other to form junctions supporting bearings and uprights 12 supporting the elements of the mechanism inside the inner cage 2.

[0047] The inertial mass 6 is arranged on a first shaft located in the inner cage 2. The first shaft is substantially perpendicular to the plane of the inertial mass 6.

[0048] The balance wheel is positioned in the upper part of the inner cage 2 so that it is visible from the outside. The balance wheel is configured to perform a rotary oscillatory motion around the first shaft, inside the inner cage 2, at a predetermined frequency.

[0049] To actuate the mechanical resonator, a second shaft 17, substantially parallel to the first shaft, is arranged in the inner cage. An intermediate wheel 19 is fixed to the second shaft 17. The intermediate wheel 19 meshes with an escapement pinion 21 arranged on a third shaft 22, which is substantially parallel to the first and second shafts 17. The third shaft 22 is arranged in the inner cage 2. The third shaft 22 also holds the escapement wheel 25, which is arranged above the escapement pinion 21. The escapement wheel 25 cooperates with a Swiss pallet fork 26 arranged perpendicular to the periphery of the escapement wheel 25. The pallet fork 26 comprises an elongated body fitted with a fork at one end, the fork being configured to cooperate with a pin of the first shaft, which cooperates with the movement of the balance wheel.The second end of the anchor 26 has two pallets arranged to cooperate with the escape wheel 25, alternately blocking its rotation, so as to rotate it in steps. The anchor 26 is carried by a fourth shaft 27 arranged in the inner cage 2.

[0050] The inner cage 2 is mounted to rotate about a first axis of rotation D1 inside the outer cage 3. The inner cage 2 includes two pivots 42, 43, each cooperating with a bearing 39, 41 of the outer cage 3. The pivots 42, 43 are arranged along the axis of rotation D1 of the inner cage. Each bearing 39, 41 has a hole for inserting the pivot 42, 43. The two pivots 42, 43 can rotate within each bearing 39, 41. Thus, the first axis of rotation D1 of the inner cage 2 passes through the outer cage 3.

[0051] The outer cage 3 comprises an annular upper part 24 and an annular lower part 28 rigidly connected to each other by uprights 31. The upper part 24 supports the inner cage 2 by means of bearings 39, 41 arranged opposite each other. The lower part 28 is provided with peripheral external teeth 32 for actuating the rotation of the outer cage 3.

[0052] According to the invention, the three-dimensional carousel 1 comprises a first ball bearing 33 arranged to allow rotation of the outer cage 3. The first ball bearing 33 is, for example, fitted into the plate or into a plate bridge (not shown in the figures). The first ball bearing 33 is arranged laterally around the lower part 28. The first ball bearing 33 includes a ring fixed relative to the plate, which retains the balls against the lower part 28.

[0053] Thus, with the first ball bearing 33 arranged on the periphery of the outer cage 3, new configurations of the regulating element are possible. In particular, in this unrealized mode, a three-dimensional carousel 1 is obtained thanks to the arrangement of this first ball bearing 33.

[0054] The outer cage 3 is mobile in rotation around a second axis of rotation D 2. The actuation of the inner cage 2 and outer cage 3 is produced by means of the drive means 15 of the clockwork movement.

[0055] The rotation of the outer cage 3 is produced in parallel with the rotation of the inner cage 2 by the drive means 15. In addition, the drive means 15 are configured to actuate the escapement mechanism 5 in parallel with the rotational movement of the outer cage 3 and in parallel with the rotational movement of the inner cage 2.

[0056] To actuate the cages 2, 3 and the escapement mechanism 5, the three-dimensional carousel 1 includes a cage drive mobile 30 arranged and centered around the first axis of rotation D 1. The cage drive unit 30 comprises a cage drive pinion 34 and a cage drive wheel 35. The cage drive unit 30 is supported by the inner cage 2. The cage drive unit 30 is arranged around the pivot 42 of the inner cage 2, near the inner edge of the first bearing 39, between the inner cage 2 and the outer cage 3. The cage drive pinion 34 is positioned towards the outside of the outer cage 3, and the cage drive wheel 35 is positioned towards the inside of the outer cage 3. The cage drive unit 30 is mounted to rotate freely relative to the inner cage 2 and the outer cage 3. In other words, the cage drive wheel 35 and the cage drive pinion 34 are not fixed to the outer cage 3 and inner cage 2.They can rotate freely, the cage drive pinion 34 and the cage drive wheel 35 being joined together, particularly in rotation.

[0057] The cage drive wheel 35 meshes with the intermediate wheel 19 of the escapement mechanism 5. Thus, the escapement wheel 25, the anchor 26 and the balance wheel movement are actuated, via the intermediate wheel 19 and the escape pinion 21, which rotate the third shaft 22. To actuate the escapement mechanism 5, the cage drive pinion 34 is meshed.

[0058] To this end, the three-dimensional carousel 1 comprises a second-stage driving ring 20 arranged movably to rotate about itself around the second axis of rotation D2 of the outer cage 3, preferably around the outer cage 3. The second-stage driving ring 20 has a ring shape comprising a first upper toothing 36 and a second peripheral toothing 37. The first upper toothing 36 has teeth oriented upwards around the entire ring. The second peripheral toothing 37 has teeth oriented outwards around the entire ring.

[0059] When the seconds driving crown 20 rotates, the upper teeth 36 drive the cage driving pinion 34, which is arranged outside the outer cage 3. Thus, the seconds driving crown 20 drives the intermediate wheel 19 of the escapement mechanism 5 via the cage driving wheel 35 of the cage driving mobile 30.

[0060] Alternatively, according to an unrepresented variant, the second driving ring is arranged inside the outer cage, preferably between the two cages.

[0061] The three-dimensional carousel 1 includes a second ball bearing 38 arranged to allow the rotation of the seconds-drive ring 20. The second ball bearing 38 is arranged under the seconds-drive ring along the entire length of the ring. The second ball bearing is, for example, fitted into the mainplate or into a mainplate bridge (not shown in the figures).

[0062] In this embodiment, the first ball bearing 33 and the second ball bearing 38 are superimposed, the second ball bearing 38 being arranged above the first ball bearing 33. The first ball bearing 33 comprising a first peripheral ring 55, and the second ball bearing 38 comprising a second peripheral ring 56, the second peripheral ring 56 being assembled to the first peripheral ring 55.

[0063] The seconds driving crown 20 is driven by the drive means 15 by gears of the gear system 13. Thus, by rotation of the seconds driving crown 20, the escapement mechanism 5 is actuated and the rotation of the inner cage 2 and the outer cage 3 is caused by a torque supplied by the drive means 15. The seconds driving crown 20 transmits the torque to the inner cage 2 and outer cage 3, as well as to the escapement mechanism 5.

[0064] A first part of the torque is transmitted to the outer cage 3 to rotate it around the second axis of rotation D 2, a second part of the torque is transmitted to the inner cage 2 to rotate it around the first axis of rotation D 1, and a third part of the torque is transmitted to the escapement mechanism 5 to actuate the escape wheel 25.

[0065] The first part of the torque is applied to the pivot 42 of the cage driver mobile 30 and causes the outer cage 3 to rotate around the second axis of rotation D 2.

[0066] The second part of the torque is applied to the intermediate wheel 19 of the escapement mechanism 5 via the cage drive wheel 30 and causes the rotation of the inner cage 2.

[0067] Thus, the drive means 15 are configured to drive the rotation of the outer cage 3 in parallel with the rotation of the inner cage 2. But the rotation of the outer cage 3 is not inextricably linked to the rotation of the inner cage 2. Thus, if the rotation of the inner cage 2 is blocked, the outer cage 3 can continue to rotate.

[0068] The third part of the torque is applied to the escape wheel 25 via the intermediate wheel 19 of the escapement mechanism 5 and the cage-driving mobile 30. The intermediate wheel 19 then pivots on itself and drives the escapement mechanism 5.

[0069] Thus, the drive means 15 are further configured to actuate the escapement mechanism 5 in parallel with the rotational movement of the outer cage 3 and in parallel with the rotational movement of the inner cage 2. Indeed, the intermediate wheel 19 distributes the torque to the escape wheel 25 on the one hand, and to a wheel 45 of the first retaining gears 40 described later, which restrain the rotation of the inner cage 2. But the rotation of the inner cage 2 is not inextricably linked to the rotation of the escape wheel 25. Thus, if the escape wheel 25 is blocked, the inner cage 2 can continue to rotate.

[0070] However, when the escape wheel 25 is blocked by the anchor 26, the second and third parts of the torque are transmitted only to the inner cage 2. Indeed, when the intermediate wheel 19 is blocked, the third part of the torque exerted on the escape wheel 25 is transferred at least in part to the inner cage 2. As such, this configuration would cause the inner cage 2 to rotate until the barrel 7 is completely hollowed out.

[0071] To control the rotational speed of the inner cage 2, and prevent it from rotating freely, the three-dimensional carousel 1 includes first retaining gears 40 of the inner cage 2, the first retaining gears 40 being arranged in the inner cage 2, so as to mesh with the intermediate wheel 19 of the escapement mechanism 5 and a wheel fixed to the outer cage 44. The wheel fixed to the outer cage 44 is movable with the outer cage 3. The wheel fixed to the outer cage 44 is mounted on the second bearing 41 of the outer cage 3, so as to be centered and perpendicular to the first axis of rotation D 1.

[0072] The wheel attached to the outer cage 44 serves to restrain the rotation of the inner cage 2, and not to allow the rotation of the inner cage 2 as in a vortex.

[0073] The first retaining gears 40 comprise two interlocking wheels, a first wheel 45 engaging with the intermediate wheel 19 of the escapement mechanism, and the second wheel 46 engaging with the wheel fixed to the outer cage 44. The two wheels 45, 46 are each mounted on a different shaft 53, 54, mounted in the inner cage 2, between the intermediate structure 57 and the lower support 9.

[0074] The first retaining gears 40 prevent the inner cage 2 from rotating freely. Indeed, the first retaining gears 40 are blocked by the intermediate wheel 19 of the escapement mechanism 5, which is held by the escape wheel 25 blocked by the anchor 26. Conversely, they are configured to rotate at a predetermined speed corresponding to the second part of the torque when the escape wheel 25 is released from the anchor 26. In this case, the second moving part 46 of the first retaining gears 40 rotates around the wheel fixed to the outer cage 44, and allows the inner cage 2 to rotate around the first axis D1.

[0075] When the escapement mechanism 5 is blocked by the anchor 26, and the inner cage 2 cannot rotate because of the first retaining gears 40, the entire torque is applied to the pivot 42 of the cage driving mobile 30. As such, such a configuration would cause the outer cage 3 to rotate until the barrel 7 is completely hollowed out.

[0076] To control the rotation of the outer cage 3 and prevent it from rotating freely, the three-dimensional carousel 1 includes second retaining gears 50 of the outer cage 3. The second retaining gears 50 are arranged outside the outer cage 3, so as to mesh with the second driving ring 20 and with the outer cage 3.

[0077] The second set of retaining gears 50 comprises a first gear wheel 47 meshing with the second peripheral teeth of the seconds driving ring 20, and a second gear wheel 48 meshing with the external peripheral teeth of the lower part of the outer cage 3. The first gear wheel 47 and the second gear wheel 48 are linked by a connecting rod 49 equipped with a pinion 51 and a third gear wheel 52. The third gear wheel 52 meshes with the first gear wheel 47, and the pinion 51 meshes with the second gear wheel 48. The second set of retaining gears 50 prevents the outer cage 3 from rotating at a speed higher than desired. The second set of retaining gears 50 connect the rotation of the outer cage 3 with the seconds driving ring 20.

[0078] When the total torque is applied to the rotation of the outer cage 3, the second retaining gears block the rotation of the outer cage 3.

[0079] Thus, when the escape wheel 25 is alternately blocked by the anchor 26, not only is the rotation of the inner cage 2 momentarily blocked, but also the rotation of the outer cage 3.

[0080] When the first retaining gears 40 and the intermediate wheel 19 are blocked, the cage drive 30 can no longer rotate. Furthermore, the second retaining gears 50 block the rotation of the outer cage 3 because they prevent the seconds drive crown 20 from turning.

[0081] One advantage of the three-dimensional carousel 1 according to the invention is that it allows for the easy selection and adjustment of different rotation speeds for the inner cage 2 and outer cage 3.

[0082] The rotational speed of the inner cage 2 and outer cage 3 depends on the size and number of teeth of the second driving crown 20, the cage driving mobile 30 and the first and second retaining gears 40,50.

[0083] The rotational speed of the inner cage 2 is determined by the first retaining gears 40 and by the rotational speed of the second driving wheel 20. The rotational speed of the outer cage 3 is determined by the second retaining gears 50 and by the speed of the second driving wheel 20. In particular, it depends respectively on the number of teeth of the first 40 and second retaining gears 50 for each cage 2, 3.

[0084] In a particular example, the outer cage 3 makes, for example, one revolution per minute, and the inner cage 2 makes, for example, one and a half revolutions per minute, while the second driving ring 20 also makes one and a half revolutions per minute.

[0085] Naturally, the invention is not limited to the embodiment of the regulating element, here a three-dimensional carousel, described with reference to the figures, and variations could be considered without departing from the scope of the invention. For example, a three-dimensional vortex could include such a peripheral ball bearing on the outer cage to rotate it around a single axis of rotation of the regulating element.
