Background of the invention

The user of a self-winding watch that is not worn permanently is compelled, when he wishes to use it, to perform the tasks of updating the displays, which can be tedious for the dates, or difficult even impossible for complications such as moon phases or other leap years in a perpetual calendar.

Detailed Description of the Preferred Embodiments

Simple means, inexpensive and space-saving, allow to remount a self-winding watch.

These means comprise means for generating a so-called rotating field, that is to say a magnetic field and / or electrostatic and / or intensity and / or variable direction as a function of time. As will be seen below, this field, said rotating, can be deployed along any profile, linear, circular, or other.

The principle is to drive a charging mobile of a mechanical energy accumulator such as a barrel, by an electromagnetic force or by eddy currents, depending on the material of this mobile. Such a mobile driven by electromagnetic forces is called here "oscillating mass", and generally adopts the form of a conventional mechanical oscillating mass disk sector. A mobile driven by eddy currents preferably has a closed surface around its pivot axis, and is comparable to a disk, and is referred to as such in the following description. An oscillating mass can be extended without limitation to a mechanical mass in motion, for example translation.

In a particular implementation, these winding means go hand in hand with watches adapted for optimal operation.

If the winding means are, in principle, capable of driving a conventional oscillating weight steel, they are not directly adapted to the best for driving a gold oscillating mass in the form of a sector that allows no not the optimal flow of eddy currents.

The invention is developed so as to allow easy adaptation of existing oscillating masses to such a winding mechanism, without significant modification of the movement. It is adapted to a simple replacement of a standard oscillating mass by a mass with a particular composition of materials.

In the variant of an eddy current drive, the addition of a disk is feasible, preferably coaxially with the mechanical oscillating weight of the watch. This original mechanical oscillating mass must then stay in place to reassemble when the watch is worn. The modification of the movement is then limited, especially as the disc can be mounted, either independent of the mechanical oscillating mass, or integral with it, to attack, or the same drive ratchet of the cylinder, or a separate ratchet. The problem of training the barrel for reassembly is well known to those skilled in the art, and is not discussed here.

The choice of materials for the winding watch is guided by the optimal behavior of the mobile depending on the type of field to which it is subject.

In the remainder of the description, "magnetically permeable" materials are defined as materials having a relative permeability of between 10 and 10,000, such as steels, which have a relative permeability close to 100 for balance shafts for example. or around 4000 for steels commonly used in electrical circuits, or other alloys whose relative permeability reaches values of 8000 to 10000.

"Magnetic" materials, for example in the case of polar masses, will be called materials capable of being magnetized so as to have a residual field of between 0.1 and 1.5 Tesla, such as for example the "Neodymium Iron Boron". a magnetic energy density Em close to 512 kJ / m ³ and giving a residual field of 0.5 to 1.3 Tesla. A lower residual field level, towards the lower part of the range can be used when combining, in a magnetization couple, such a magnetic material with a magnetically permeable antagonist component of high permeability, closer to 10000, in the range of 100 to 10,000.

Ferromagnetic materials are materials whose characteristics are: saturation field Bs> 0 at temperature T = 23 ° C, coercive field Hc> 0 at temperature T = 23 ° C, maximum magnetic permeability μ _R > 2 at the temperature T = 23 ° C, Curie temperature Tc> 60 ° C.

More particularly, those whose coercive field is small (Hc <1000 A / m) and with a low hysteresis cycle will be termed "magnetically soft materials".

More particularly, those whose coercive field is large (Hc> 3000 A / m) and with a large hysteresis cycle, for example permanent magnets, will be described as "magnetically hard materials".

"Paramagnetic" materials will be referred to as materials having a relative magnetic permeability of between 1.0001 and 100, for example for spacers interposed between a magnetic material and a magnetically permeable antagonist component, or alternatively between two magnetic materials, for example a spacer between a component and a polar mass. For example, weakly paramagnetic materials are: aluminum, gold, brass or the like (magnetic permeability less than 2).

They are described with a winding device 300, or a watch assembly 400 comprising a winding device 300 and at least one watch 200.

The winding mobile 50 automatic winding watch comprises a guide 2 at its pivot axis D. This mobile 50 is registered in a cylinder of maximum radius RMAX centered on this axis D, and comprises drive means of a mechanism for recharging energy, such as ratchet for driving a barrel, or the like.

According to the invention, this mobile 50 comprises, or at least one ferromagnetic or magnetized portion for driving the mobile 50 by a variable magnetic field, or an electrified portion for driving the mobile 50 by a variable electrostatic field, or a paramagnetic conductive ring surrounding the pivot axis D on a sufficiently large diameter for driving the mobile 50 by eddy currents. In the latter case, it is understood that this conductive ring is preferably at the periphery of the mobile 50, which is then called "disk" 20.

According to the invention, as visible on the figure 2 , the winding mobile 50 comprises at least one magnetic oscillating mass 1, which comprises a first ferromagnetic inner portion 8 extending on radii below the minimum radius RMIN of a second peripheral portion 9 of heavy metal. By heavy metal is meant a material of atomic number between 73 and 79, or an alloy comprising at least 80% of heavy metal of atomic number between 73 and 79.

In a particular embodiment, allowing a large inertia of the magnetic oscillating mass 1, the second peripheral portion 9 comprises at least 50% of tungsten.

In another particular particular embodiment, the second peripheral portion 9 comprises at least 50% of tungsten and at least 20% of gold.

In combination with one of these two embodiments based on tungsten, in yet another particular embodiment, the second peripheral portion 9 comprises at least 20% iron.

In a particular embodiment, the first inner portion 8 is made of magnetically soft material.

The figure 3 illustrates a variant of the figure 2 wherein the magnetic oscillating mass 1 has openings 40 at the first inner portion 8.

In another variant not illustrated, the winding mobile 50 comprises at least one electrified portion for driving the mobile 50 by a variable electrostatic field, which advantageously comprises electrets.

It is understood that it is possible to accumulate, on the same mobile, and especially at different tracks, on different diameters, or / and on different faces, or / and on different floors, areas likely to be driven, or by magnetic force, or by electrostatic force, or by eddy currents: the possibilities of mixing are numerous, and are not exposed here so as not to overload the present description.

For a variant close to the invention, with eddy current drive, the figure 5 represents a winding mobile 50 which comprises at least one disk 20 comprising at least one paramagnetic conductive ring surrounding said pivot axis D for driving said mobile 50 by eddy currents.

The invention also relates, inside the watch, an automatic winding watch 10 comprising at least one mechanical oscillating mass 3 for recharging mechanical energy of at least one barrel or accumulator.

According to the invention, this winding device 10 comprises, in addition to or instead of this at least one mechanical oscillating weight 3, at least one such winding device 50 presented above.

In particular, at least one winding mobile 50 comprises at least one cutout 40.

The invention also relates to a watch movement 100 comprising at least one barrel or a mechanical energy accumulator, and at least one such automatic winding device 10.

The invention also relates to a watch 200 with automatic winding, comprising at least one such movement 100, and / or at least one cylinder or a mechanical energy accumulator and at least one such automatic winding 10.

In a neighboring embodiment of the invention, the watch 200 comprises, for the mechanical energy recharging of at least one cylinder or accumulator, a paramagnetic conductive disk 20 arranged for recharging mechanical energy of at least one barrel or accumulator, or more than one such disc 20.

In a context similar to the invention, a device 300 for automatic watch winding comprises at least one power supply means or an electric accumulator, and at least one receptacle support 301 for a watch.

The power supply means or the electric accumulator is advantageously housed in a base dressed with photovoltaic cells 309, as visible on the figure 1 , so as to supply electric means for generating fields.

This receptacle support 301 comprises a bearing surface 302 intended to support the bottom of a watch.

This device 300 comprises generating means 310 of a magnetic and / or electrostatic field arranged in a fixed position at a transmission zone 303 under this bearing surface 302, and generating, at least a track or field sector 340, at least one magnetic field and / or electrostatic so-called "turning" direction and / or intensity and / or direction as a function of time.

In a particular embodiment according to the figure 8 , the track or the field sector 340 comprises at least one linear segment 307 of a substantially linear emission zone 303. The generation means 310 generate, at this at least one linear segment 307, at least one magnetic or electrostatic field of substantially orthogonal or orthogonal direction at the bearing surface 302 and intensity and / or sense varies with time.

The figure 9 illustrates a variant where the track or the field sector 340 comprises several such disjoint linear segments 307A, 307B: at each of them is exerted successively such a rotating field.

In a preferred embodiment illustrated by the figure 7 , the track or the field sector 340 comprises at least one angular sector 304 of a substantially annular emission zone 303. The generating means 310 generate, at this at least one angular sector 304, at least one magnetic or / and electrostatic field of substantially orthogonal or orthogonal direction, at the bearing surface 302 and intensity or / and sense varies with time.

In a particular embodiment, the generating means 310 generate, on the transmission zone 303, a plurality of such magnetic and / or electrostatic fields, parallel to each other orthogonal to the bearing surface 302 and each of intensity or and of direction that varies with time.

In an advantageous embodiment as visible on the figure 1 the generation means 310 comprise a network of coils 305 at all or part of the transmission zone 303.

In a particular embodiment illustrated by the figures 1 , 7, 8, and 9 , the generation means 310 generate the magnetic field and / or electrostatic on an angular sector 304 centered on a median axis of the bearing surface 302 and less than 240 ° reciprocating from one end to the other. Another of this angular sector 304. The axis D of the winding of the watch to go up is substantially coincident with this median axis when the watch is placed by its bottom 201 on the bearing surface 302.

The trajectory 308 of the receiving track of the driving wheel 50 is illustrated on the Figures 8 and 9 . The figure 7 shows the limits 306 of the transmission zone 303 actually active in such a case. It will be noted that the generation means 310 may be, if necessary, controlled to reverse the fields and brake the mobile 50 if its rotational speed is too high.

In another embodiment, the generating means 310 generate the magnetic field and / or electrostatic in a uniform direction of rotation over all 360 ° of the bearing surface 302.

Naturally, the physical means for producing the rotating fields may be identical, for example a complete annular network of coils 305, some or all of which, depending on the management mode chosen, are activated. For this purpose, the device 300 advantageously comprises regulation and control means 320 for controlling the generation means 310.

In this particular case, the regulation and control means 320 comprise time management means and control the generation of the magnetic and / or electrostatic field at predefined times or resulting from the reception of a signal.

These control and control means 320 control the generation of the magnetic and / or electrostatic field in the form of a so-called "rotating" field with a speed Ω of rotation along the angular sector 304 or the transmission zone 303.

In a particular management mode, the regulation and control means 320 accelerate the rotational speed Ω of said rotating field, from the start time of the generation of the field to an acceleration stop time after a period of time. predefined.

Advantageously, the regulation and control means 320 comprise receiving means 330 arranged for measuring position and / or speed of a winding mobile 50 driven under the effect of the variation of the magnetic and / or electrostatic field, and are capable of exerting reversing fields in the event of excessive rotational speed of a mobile 50.

It is understood that, if the transmission zone 303 preferably comprises coils - or, more generally, field generation means - over its entire periphery, the regulation and control means 320 make it possible to define particular cycles of field variation. For example, it is possible to first move a mass in motion in a reciprocating motion of a certain amplitude, then to modify this amplitude, or even to transform the reciprocating motion in continuous motion. This tool is extremely flexible, and is limited only by the capabilities of the control means 320.

In this context of the invention, a watch assembly 400 includes such a device 300, and at least one such watch 200.

• ou bien au moins une masse « oscillante » magnétique 1, ou une masse « oscillante » 5 dite à aimant, que comporte cette au moins une montre 200, pour le rechargement en énergie mécanique d'au moins un barillet ou accumulateur,
• ou bien d'au moins un disque 20 conducteur paramagnétique coaxial à cette masse « oscillante » mécanique 3, que comporte cette au moins une montre 200, et agencé comme cette masse « oscillante » mécanique 3 pour le rechargement en énergie mécanique d'au moins un barillet ou accumulateur,
• ou bien d'au moins une masse « oscillante » magnétique 1 que comporte cette au moins une montre 200, et d'au moins un disque conducteur 20 conducteur paramagnétique coaxial à la masse « oscillante » mécanique 3, que comporte à la fois la au moins une montre 200 pour le rechargement en énergie mécanique d'au moins un barillet ou accumulateur,

pour l'entraînement, selon le cas, de la au moins une masse « oscillante » magnétique 1 ou masse « oscillante » 5 dite à aimant par couplage magnétique, ou/et de cet au moins un disque 20 par courants de Foucault.More particularly, the device 300 of this assembly 400 includes such control and control means 320 for the control of the generation means 310, and these control and control means 320 and these generation means 310 are adapted and formatted for the first time. driving at least one winding mobile 50 which comprises:

• or at least one "oscillating" magnetic mass 1, or an "oscillating" mass 5 called magnet, that includes this at least one watch 200, for recharging mechanical energy of at least one cylinder or accumulator,
• or at least one paramagnetic conductive disk 20 coaxial with this "oscillating" mechanical mass 3, which this at least one watch 200 comprises, and arranged like this "oscillating" mechanical mass 3 for the mechanical energy recharging of at least a cylinder or accumulator,
• or at least one "oscillating" magnetic mass 1 that includes this at least one watch 200, and at least one conductive conductor disc 20 coaxial conductive to the "oscillating" mechanical mass 3, which includes both the at least one watch 200 for recharging mechanical energy of at least one cylinder or accumulator,

for the drive, as the case may be, of the at least one "oscillating" magnetic mass 1 or "oscillating" mass 5 called magnet by magnetic coupling, and / or of this at least one disk 20 by eddy currents.

Different winding architectures can be used within the watch.

It is thus possible to separate the functions of mechanical winding and magnetic / electrostatic winding / eddy currents, for example with elements each dedicated to one of these functions, oscillating on one another, integral or otherwise, coupled or not, and preferably coaxial. This allows the optimization of each of these elements for its own function, and, overall, allows the limitation of the bulk and weight of the winding mechanism.

The paralleling (or series) of mechanical winding functions can be provided by subjecting the watch to acceleration of magnetic / electrostatic / eddy current origin.

It is easy, thanks to the invention, to transform a watch already having a conventional mechanical oscillating weight, by adding another mobile recharging, magnetic oscillating mass, magnet oscillating weight, or, in an embodiment close to the invention, a paramagnetic conductive disk.

Each of these mobiles can attack the energy accumulator, either unitarily or by the same mechanism as the already existing mechanical oscillating mass.

The fact of dissociating the functions allows, again, to have a rotary movement for the mechanical winding, and another movement, for example in translation for the magnetic part, or vice versa. In this case, it is necessary to couple the two specific axes towards the barrel. The advantage is to open other mechanical options to move this movement in translation on a more restricted area of the movement. In this case, there is movement back and forth along an axis, and more only according to an angular sector.

In case of alternative operation, the back and forth can be limited either by the regulation and control means 320, or by a mechanical limitation, or the combination of these two solutions.

The complete, continuous, and accelerated rotation of the winding mobile 50 is a special case that strongly personalizes this watch ensemble.

When the so-called "turning" field is in fact alternative, it can, in a simplified embodiment, be alternated in two positions on the same axis, which is very simple to do in a winder.

Another solution consists in setting up a magnet that moves on an axis in the winding device, and in translation drives the magnetic oscillating mass 1 or the magnet oscillating mass 5, as the case may be, on the side of the magnet. watch 200.

Most of the usual movements are two-way winding, for which the torque is about the same in both directions.

Regarding unidirectional winding movements, the mass is almost free in one direction.

The unbalance of the mass generally varies from 70 to 300 μNm.

The inertia is of the order of 200 g.mm2.

An example of dimensioning is based on the "ETA A16" movement: a 100% reinforced barrel retains the oscillating mass in an angle of 25 ° to 45 °, which corresponds to a maximum torque of 210 μNm (= unbalance x 45) °)

To achieve a rotation of the mass of 90 °, it is necessary to add the unbalanced couples and spring barrel, about 500 μN.m

To ensure the recharge, it is necessary to exceed the dead angles of the ratchet wheels and the barrel pawl, that is to say that a useful angular displacement of at least 30 ° is necessary to cross the ratchet catch of the mechanism. reverser and the ratchet catch of the barrel ratchet.

For winding by the crown, do not exceed, at the rod, a speed of 100 revolutions / min, which equates to a speed of 4000 revolutions / min of the oscillating mass.

It typically takes 2000 turns of oscillating weight to completely wind the watch, for at least 72 hours of power reserve.

The sintered tungsten has a density of about 18 g / cm3.

The heart of the oscillating mass is generally brass, with a thickness of the order of 0.3 to 0.4 mm.

It is possible to mix tungsten beads with iron balls.

This winding device 300 allows, with a speed of rotation Ω of 5 revolutions per second, to carry out a complete reassembly of any watch in less than 5 minutes.

The gap between the coils 305 and the mobile winding 50 is chosen in the range of 2 to 3 mm.
