Description

Technical Field

[0001] The present invention relates to a watch assembly comprising at least one watch and an adjustment tool for driving moving parts inside the watch through the watch case without direct contact to achieve the purpose of setting and / or recharging energy.

[0002] The present invention also relates to a method for using such a clock component.

[0003] The present invention also relates to a watch for use in the watch components of the present invention.

[0004] This invention relates to the field of setting and / or drive control mechanisms for timepieces. Background Technology

[0005] There are many mechanical systems used to set the functions of a watch through the case, such as pushers, crowns, and so on. However, all mechanical components extending through the case must be waterproof, for example, by using O-rings or other joints, which presents a problem.

[0006] Furthermore, once the watch is closed, certain movement settings (such as the rate) are better adjusted because the case-fitting process often causes discrepancies between the components on the movement and the assembled watch.

[0007] For these two specific reasons, a magnetic coupling device is desired for rotating the internal components of the watch using an external tool.

[0008] Document EP4124584 describes a magnetic coupling element that can transmit high torques inside a watch case. However, the two canceling magnetic parts must be close to each other, which excludes automatic watches and thick case backs.

[0009] Document EP3579061 describes a device for correcting the state of a quartz watch. Depending on the required correction, a magnet rotating beneath the watch directly drives a motor rotor in one or the other direction. Summary of the Invention

[0010] The present invention proposes the use of a device that transmits a couple or force through the watch case using a magnetic coupler to perform mechanical settings (e.g., rate setting or state setting) or to wind the watch or perform other operations once the watch is assembled (movement is installed).

[0011] The proposal involves placing a small bipolar Lavet motor rotor magnet within the watch movement and positioning a high-reduction-ratio gear train between the magnet and the object to be rotated to achieve the necessary torque. The rotor can then be driven from a relatively large distance using an external bipolar magnet, making it compatible with any type of watch, particularly automatic watches or those with thick case backs.

[0012] Therefore, the present invention relates to a watch assembly according to claim 1.

[0013] The present invention also relates to a method for using such a clock component, thereby enabling compensation for mechanical slack before proceeding with actual micrometer setting.

[0014] The present invention also relates to a watch as defined by claims 22 to 34. Attached Figure Description

Detailed Implementation

[0016] Patent EP3252545 describes a magnetic coupling system between the inside and outside of a housing, which allows the winding stem to be coupled to a rate setting system by changing the inertia of a special balance wheel. Specifically, an external magnetic key with a permanent magnet, through magnetic coupling, rotates an inner ring with a ferromagnetic target. This ring is either held axially by a resilient abutment against a brake lever or rotated-locked by a blocking device fixed to the spindle, thus ensuring its resistance to rotational shocks.

[0017] This highly efficient system essentially acts as a repeater for the rotating couple on the spindle, the sole guarantor of the internal mechanical function (in this case, the inertial variation of the special balance wheel). Therefore, by itself, it is unsuitable for providing the couple required for the setup in question or for energy recharging. The magnetic feedthrough system must be coupled with another energy supply system, which must also be suitable for the magnetic repeater. All of this leads to a relatively complex assembly.

[0018] This invention provides a system related to the system described in patent EP3252545, but which does not rely on any buttons or spindles and is therefore capable of generating direct couples / forces. This new system is also encrypted and has its own mechanical locking / unlocking function and is easier to operate. The encryption of this invention is related to: the radial and axial relative spatial positions of the setting tool with respect to the internal control movement; and the correlation between the number of rotations (assigned to the external drive movement included in the setting tool) and the rotation (assigned to the internal control movement via a control movement magnetically engaged with the external drive movement and via a reduction gear train with a high reduction ratio).

[0019] The invention includes placing a small magnet, particularly a bipolar magnet (such as a Lavet motor rotor magnet), within a watch movement, and positioning a high-reduction-ratio gear train between the magnet and the object to be rotated to obtain the necessary torque. The rotor can be driven from a relatively large distance by an external magnet, particularly a bipolar magnet.

[0020] A high reduction ratio gear system is essential because its use enables the controlled moving parts inside the watch to make extremely small angular movements.

[0021] In fact, documents EP4092494, CH718656, and CH716962 submitted by ETA Manufacture Horlogère Suisse describe near-field watch setting systems, and documents CH712578, CH716920, CH719089, EP4174584, and CH713306 submitted by Swatch Group Research and Development Ltd describe mechanisms for rate setting, for driving control components, or even for frequency adjustment without contact from outside the watch. These various systems all utilize magnetic fields, but in direct drive, it is impossible to compensate for mechanical slack or to perform simple micrometer setting of such internal controlled moving parts.

[0022] Therefore, the present invention relates to a watch assembly 2000, which includes at least one watch 1000 and at least one setting tool 200, said at least one setting tool being arranged such that an internal moving element 1 included in each watch 1000 of the watch assembly 2000 can be driven via the case 10 on each watch 1000 without direct contact in order to perform setting and / or recharging. The internal control moving element 1 can pivot about a first axis D1.

[0023] Each setting tool 200 includes means for generating an external magnetic field that rotates about an external axis DE and is arranged to engage (coopérer, or “collaborate”) with an internal magnetic or ferromagnetic region 11 included in an internal control moving member 1 in a complementary attractive or repulsive manner so as to rotate the internal control moving member 1.

[0024] Each watch 1000 includes an internal controlled movement 2 that is pivotable within the watch case 10 about a second axis D2, and is arranged to be driven by an internal control movement 1. In a non-limiting embodiment illustrated in the figures, the internal control movement 1 pivots between an upper rod 41 and a plate 42, and the internal controlled movement 2 also pivots between the same upper rod 41 and plate 42, to optimally reduce the volume occupied by the kinematics used to drive the internal controlled movement 2 by the internal control movement 1.

[0025] According to the present invention, in each watch 1000, the internal control moving member 1 includes a control pinion 13 that meshes with an inlet moving member 31 included in a reduction gear system 30, in which an outlet moving member 32 meshes with an internal controlled moving member 2.

[0026] More specifically, and as can be seen in the accompanying drawings, to keep its size to a minimum, the reduction gear train is very compact and includes stepped wheels distributed around at least two separate axes of rotation, referred to as transmission axes. In a particular, advantageous, but non-limiting embodiment illustrated in the drawings, the reduction gear train 30 includes a first transmission axis D3 and a second transmission axis D4, two overlapping stepped wheels each having the same diameter, namely, first stepped wheels 32, 35, 31 around the first transmission axis D3, and second stepped wheels 33, 34 around the second transmission axis D4. Advantageously, the first stepped wheels 32, 35, 31 and the second stepped wheels 33, 34 are all identical. Advantageously, in a non-limiting embodiment illustrated in the drawings, the first stepped wheels 32, 35, 31 and the second stepped wheels 33, 34 pivot between the same upper rod 41 and plate 42, thereby guiding the internal controlled movement 2 and the internal control movement 1. Therefore, the reduction gear train 30 occupies a very small volume. Preferably, and for this arrangement, the reduction gear train 30 occupies less than 2% of the internal volume of the case 10.

[0027] Naturally, depending on the space in the case available for rotation in the reduction gear train, other arrangements can be used, such as having some of its wheels pivot about a first axis D1 or a second axis D2.

[0028] Furthermore, more specifically, the clock assembly 2000 includes means for counting the number of revolutions of the externally driven moving member 20 to accurately determine the pivot angle of the internally controlled moving member 2, and / or means for determining and / or visualizing the angular position of the internally controlled moving member 2. When the externally driven moving member 20 preferably pivots at a constant speed, these counting means may also be means for measuring duration.

[0029] In fact, the present invention is applicable to both watches 1000 in which the internal controlled moving part 2 is visible and watches in which the internal controlled moving part 2 is not visible and is concealed by the movement or other parts of the watch.

[0030] Figure 4 and Figure 5 A variant is illustrated in which the upper lever 41 includes a scale 50 for marking the angular position of an indicator 25 carried by an internal controlled movement 2 (in this case, a worm cam), which acts as an upper guide for the carrier spindle of the internal control movement 1, the internal controlled movement 2, and the stepped wheel of the reduction gear train 30.

[0031] More specifically, the setting tool 200 includes means for relative positioning with respect to the case 10 to optimally position the outer axis DE, which is parallel to the first axis D1 and has a center distance E less than or equal to a predetermined value between the outer axis DE and the first axis D1; ​​more specifically, and as in Figure 1 As can be seen, the predetermined value is the mechanical slack value between the setting tool 200 and the case 10, and the outer axis DE and the first axis D1 are then substantially aligned.

[0032] In the first embodiment illustrated in the accompanying drawings, each setting tool 200 includes means for pivoting an externally driven moving part 20 outside the watch about an external axis DE.

[0033] More specifically, in this first embodiment, the means for generating the rotating external magnetic field includes means for pivoting an external drive movement 20 outside the watch about an external axis DE, and the external drive movement 20 includes at least one external multipole magnet, the at least one external multipole magnet including external magnetic regions 21N; 21S with alternating polarities, these external magnetic regions being arranged to engage with internal magnetic regions 11 or ferromagnetic regions included in the internal control movement 1 in a complementary attractive or repulsive manner so as to rotate the internal control movement 1.

[0034] Each setting tool 200 includes external magnetic zones 21N, 21S with alternating polarities, which are arranged to engage in a complementary manner with internal magnetic zones 11N, 11S or internal ferromagnetic zones included in the internal control movement 1 to drive the first internal movement 1.

[0035] Preferably, the drive moving part 20 includes at least one external multipole magnet, particularly a bipole magnet, said at least one external multipole magnet including such external magnetic regions 21N, 21S with alternating polarities.

[0036] More specifically, the setting tool 200 includes means for axially positioning the external multipole magnet at a predetermined distance relative to the case 10 so as to precisely position it relative to the internal control movement 1 along the direction of the first axis D1. Therefore, the relative positioning means between the case 10 and the setting tool 200 defines a magnetic distance DM between the nearest end surfaces of the external magnetic zones 21N, 21S on one hand and the internal magnetic zones 11S, 11N on the other. Of course, it is advantageous to keep the magnetic distance DM as small as possible. However, it should be noted that the present invention offers the advantage of accommodating a magnetic distance DM of several millimeters, which allows the internal control movement to be driven via a thick case back, or via an automatic gear train, or even via another mechanism inside the watch, and this also allows the internal control movement to be driven from the top of the watch via the crystal, thereby allowing two setting tools with different functions to be mounted simultaneously on either side of the watch, for example, one for setting the watch's rate and the other for setting the watch's state.

[0037] This invention defines a law based on parameters consisting of the value of the center distance E, the magnetic distance DM, the properties and dimensions of the external magnetic zone, the properties and dimensions of the internal magnetic zone, and the architecture of the reduction gear system. This law determines the value of the pivot angle of the internal controlled moving member 2 based on the number of revolutions given to the external driving moving member 20. The user has an abacus or computer program, enabling the user to accurately determine the control to be used to achieve the desired settings.

[0038] In a second embodiment (not shown), the apparatus for generating the rotating external magnetic field includes means for supplying power and distributing current to a plurality of even-numbered coils offset at an angle around an external axis DE (e.g., but not limited to, 90° to each other) and arranged to generate a rotating electromagnetic field (similar to a brushless electric motor) capable of engaging with an internal magnetic region 11 or ferromagnetic region included in an internal control movement 1 in a complementary attractive or repulsive manner to rotate the internal control movement 1. For example, the coils are angularly spaced, identical, and sequentially powered in a single direction to generate the rotating field. Specifically, a tool can be used to test the mechanical parts of a quartz watch; this tool is distributed by "Esslinger®" under the name "Horotec Watch Turbo Tester®" with part numbers MSA 19.107 or 64.107. This tool generates a field rotating at a speed of tens of revolutions per second.

[0039] It will be understood that, depending on the arrangement of the reduction gear train 30, the present invention can be used in a variety of applications. A multiplier gear train can be suitable for the winding function, while a divisor gear train is particularly well-suited for setting functions, especially micro-setting. This micro-setting function, usually performed by watchmakers, is always a delicate function, as the precise setting just made can be changed simply by closing the watch case. A device that allows micro-setting without opening the watch case is also very useful.

[0040] In a specific and preferred embodiment, the accompanying drawings illustrate this latter alternative to the reducer gear train specifically designed for micro-setting functions, wherein the reduction gear train 30 occupies a very small portion of the watch's internal volume, particularly less than 5%, particularly less than or equal to 2%, and has a very low mass as a percentage of the watch's total mass, particularly less than or equal to 5%, particularly less than or equal to 2%. To achieve extremely precise micro-setting, the gear reduction factor is high, above 1,000, particularly above 10,000. These mass and space constraints naturally imply that the torque transmitted by the kinematic chain is severely limited, particularly to less than 30 milliNm. The selection of a micro-manufacturing method is essential for producing the gears and pinions of the reduction gear train 30. In practice, to ensure that the setting is unaffected by any interference from external magnetic fields, the reduction gear train 30 and the internal controlled moving parts 2 are preferably made of non-magnetic materials. Moreover, more specifically, the reduction gear system 30 includes stepped wheels made of non-magnetic materials, or stepped wheels made of silicon and / or silicon oxide and / or silicon carbide and / or silicon nitride and / or nickel-phosphorus alloys (with appropriate phosphorus content to remain non-magnetic, typically greater than or equal to 12%) and / or amorphous or partially amorphous non-magnetic metal alloys, or polymers, etc.

[0041] More specifically, the means for pivoting the drive moving member 20 is arranged to drive the drive moving member 20 at an angular velocity greater than or equal to 10 revolutions per second, particularly greater than or equal to 40 revolutions per second.

[0042] More specifically, the internal control moving part 1 includes at least one magnet, and particularly includes at least one internal multipole magnet with alternating polarities 11N, 11S, especially bipolar and including an internal magnetic region.

[0043] More specifically, the internal control moving element 1 is or includes a Lavet motor rotor.

[0044] More specifically, the reduction gear system 30 and the internal controlled moving parts 2 are made of non-magnetic materials.

[0045] More specifically, each watch 1000 includes at least one device for holding the internal control moving member 1 in place by applying an elastic mechanical positioning couple and / or by applying residual magnetism, so as to keep the internal control moving member 1 stationary in the absence of interaction from an external magnetic field. For example, a ferromagnetic pin near the rotor formed by the internal control moving member 1 enables the generation of a positioning couple for the rotor, which can be easily overcome during the setting phase by applying an external rotating magnetic field.

[0046] More specifically, in an embodiment not shown, the first axis D1 and the second axis D2 are aligned.

[0047] In a particular variant not shown, the first internal moving member 1 is ferromagnetic. More specifically, the first internal ferromagnetic moving member 1 then has a specific form designed to minimize the attractive, rotational, or repulsive effects of a uniform external magnetic field, typically 1.5 Tesla, and to minimize the rotation of the first internal moving member 1, particularly the ferromagnetic moving member, under the influence of a uniform external magnetic field, typically 1.5 Tesla.

[0048] More specifically, the means for pivoting the drive moving member 20 is arranged to drive the drive moving member 20 at an angular velocity greater than or equal to 40 revolutions per second.

[0049] More specifically, the reduction gear system 30 produces a reduction factor greater than or equal to 10,000.

[0050] More specifically, the reduction gear system 30 produces a couple multiplier of more than 80,000.

[0051] It will be understood that a user or repairman outside the designer's network can attempt to rotate the first internal moving part 1 using a single magnet of any size and strength, and can drive the reduction gear system and the second controlled moving part, but the external operator is unaware of the laws that form the basis for rotating the controlled internal moving part, and cannot achieve the expected accurate setting.

[0052] More specifically, at least one watch 1000 in the watch assembly 2000 is a non-magnetic watch. Even more specifically, each watch 1000 in the watch assembly 2000 is a non-magnetic watch.

[0053] More specifically, at least one watch 1000 in the watch assembly 2000 is a mechanical watch. Even more specifically, every watch 1000 in the watch assembly 2000 is a mechanical watch.

[0054] More specifically, at least one watch 1000 in the watch assembly 2000 is an electromechanical or electronic watch. Even more specifically, each watch 1000 in the watch assembly 2000 is an electromechanical or electronic watch.

[0055] More specifically, the second internal moving member 2 is a control moving member for setting the rate of an adjusting member included in at least one watch 1000. The present invention is particularly well-suited for setting the rate of the balance wheel by modifying the stiffness of the balance wheel.

[0056] More specifically, the second internal moving part 2 is a control moving part for setting the time of at least one watch 1000.

[0057] More specifically, the second internal moving part 2 is a control moving part for setting the calendar mechanism included in at least one watch 1000.

[0058] More specifically, the second internal moving part 2 is a control moving part for winding at least one watch 1000.

[0059] More specifically, the second internal moving part 2 is a moving part for controlling the setting of the alarm mechanism and / or timekeeping operation included in at least one watch 1000.

[0060] More specifically, the internal controlled moving part 2 is a moving part used to control the setting of a sensor calibration mechanism included in at least one watch 1000 for a function of an altimeter, depth gauge, or compass.

[0061] More specifically, the first internal moving part 1 is invisible to the user of at least one watch 1000.

[0062] More specifically, at least one watch 1000 does not have an external mechanical setting member extending through the case of the watch 1000.

[0063] More specifically, at least one watch 1000 is waterproof to gases and ambient humidity, and its case includes at least one sealing area suitable for undergoing metal, ceramic or glass sealing treatment in a vacuum or neutral gas atmosphere.

[0064] More specifically, at least one watch 1000 is sealed to be placed under a vacuum so as to be unaffected by changes in internal pressure caused by temperature variations.

[0065] More specifically, at least one watch 1000 is equipped with an RFID chip or a passive identification device, thereby enabling direct identification of the nature of the watch component 2000 to which the watch 1000 belongs and the setting tool 200 to be used for after-sales purposes.

[0066] It should be understood that the engagement between the case 10 and the setting tool 200, as well as the positioning of the first internal moving part 1, ensures that the system cannot be tampered with if a third party is unaware of the internal positioning of the internal control moving part 1, and more importantly, unaware of the law that links the driving of the external drive moving part 20 with the pivoting of the internal controlled moving part 2.

[0067] The present invention also relates to a method for using such a clock assembly 2000, thereby enabling compensation for mechanical slack before proceeding with actual micrometer setting: in a first step, an internal control moving member 1 is exposed to an external rotating magnetic field at an intensity below a first predetermined threshold and for a duration shorter than a first predetermined duration for slack compensation drive in the mechanical kinematic chain between the internal control moving member 1 and the internal controlled moving member 2; and in a second step, the internal control moving member 1 is exposed to an external rotating magnetic field at an intensity greater than a second predetermined threshold and for a duration greater than a second predetermined duration for synchronous drive of the internal controlled moving member 2 by the internal control moving member 1 via the reduction gear train 30.

[0068] As a non-limiting example, the internal control moving part 1 and the internal controlled moving part 2 pivot between two links less than 2 mm apart, and five gears in the reduction gear train 30 rotate between these two links, wherein the double-gear Liga gear has an outer diameter of 3 mm, a gear ratio of 7, and a total reduction ratio of 16,800. When projected into a plane along the direction of the first axis D1, the entire mechanism formed by the internal control moving part 1, the reduction gear train 30, and the internal controlled moving part 2 occupies a space of approximately 3 mm x 6 mm. The internal control moving part 1 is a Lavet motor rotor with a diameter of 1.4 mm and a thickness of 0.5 mm. The external drive moving part 20 has a diameter of 20 mm and a thickness of 2 mm, and includes neodymium iron boron magnets. The torque applied by the external drive moving part 20 to the internal control moving part 1 is 3 microNm, the portion of the torque dedicated to positioning the rotor is 0.5 microNm, and the portion of the torque that can be transmitted to the reduction gear train 30 is 2.5 microNm. At the outlet of the reduction gear system 30, a controllable moving part 2 (e.g., such as...) is used. Figure 4 The useful couple of the worm cam shown is 21 milliNm. In applications involving rate setting, one revolution of the internal controlled movement 2 corresponds to a 10-second setting. Therefore, a 0.1-second setting corresponds to 168 revolutions of the internal control movement 1. If the motor driving the external drive movement 20 rotates at 50 revolutions per second, it takes 40 seconds to set 1 second very accurately on the internal controlled movement 2. In this case, the system volume accounts for only 1% to 2% of the caliber volume.

[0069] The effective size of the system must be kept small relative to the main features inside the watch.

[0070] The apparatus according to the invention should only be handled in the factory, in a professional shop, or through the designer's authorized after-sales service to avoid any unintentional interference by the customer or a third party.

[0071] This system can completely replace conventional buttons and stems, making it possible to produce automatic watches or other watches that are far more water-resistant than current watches.
