Definitions
- the invention relates to a watch assembly comprising at least one watch, and an adjustment tool, for driving without direct contact a first moving body internal to the watch through its case, for adjustment and/or recharging with energy.
- the invention relates to the field of adjustment and/or drive control mechanisms for timepieces.
- the invention proposes to implement means for transmitting a torque or a force through a watch casing using a magneto-coupler, in order to carry out a mechanical adjustment, for example an adjustment of the rate, once the watch is finished (interlocked movement).
- the invention relates to a timepiece assembly according to claim 1.
- EP3252545A1 describes a magnetic coupling system between the inside and the outside of the casing, which system makes it possible to engage the winding stem towards a rate adjustment system by changing the inertia of a special balance wheel.
- an external encrypted magnetic key equipped with permanent magnets, rotates an internal ring, equipped with ferromagnetic targets, by magneto-mechanical coupling.
- the ring is locked in rotation, either by the axial elastic retention against a blocker, or by a locking integral with the axial movement of the rod, thus guaranteeing its retention vis-à-vis rotary shocks.
- This high-performance system essentially serves to relay the rotation torque of the stem, the only guarantor of the internal mechanical function, in this case the change of inertia of the special balance wheel. It is therefore not capable of supplying, on its own, the desired torque for the adjustment in question, nor for recharging energy.
- the magnetic bushing system must cooperate with another energy supply system, which must also be adapted to the magnetic relay. The whole therefore constitutes a relatively complex whole.
- the invention proposes a system similar to that described by the patent document EP3252545A1 , but independent of any pusher or rod, and therefore able to produce direct torque/force, this new system also being encrypted and having a own mechanical locking/disengaging function, the execution of which is simplified.
- the invention thus relates to a watch assembly 2000 comprising at least one watch 1000, and at least one adjustment tool 200, which is arranged to allow the driving without direct contact of a first internal mobile 1 that each watch 1000 of this watch assembly 2000, through a box 10 that each watch 1000 includes, for the execution of an adjustment and/or an energy recharge.
- Each adjustment tool 200 comprises first magnetic zones 210, which are arranged to cooperate in a complementary manner, in attraction or repulsion, with the first internal mobile 1 which is ferromagnetic or which comprises second magnetic zones.
- the first internal mobile 1 is mobile in pivoting about a first axis D1, and is also axially mobile in the direction of the first axis D1 against an elastic return means 5 which is fixed to the case 10, or to an element 2 of the case 10 or fixed to the case 10, or else to a fixed element of the internal structure of the watch 1000 such as a plate or the like.
- This axial mobility of the first internal mobile 1 is exerted between, on the one hand an active position in which the adjustment tool 200 is positioned against the watch 1000 or in the vicinity of the watch 1000 so as to attract in the alternative illustrated operation in attraction, or respectively pushing back in the other alternative of operation in repulsion, the first internal mobile 1 towards an end-of-travel surface 6 that comprises the elastic return means 5 or the element 2 or the case 10, or even a fixed element of the internal structure of the watch 1000, in a clutch position between a first drive element 3 secured to the first internal mobile 1 or constituted by the first internal mobile 1 and a second internal mobile 7 internal to the box 10, and on the other hand an inactive position in the absence of the adjustment tool 200, in which inactive position the elastic return means 5 maintains the first drive element 3, or the first internal mobile 1 itself according to the adopted configuration, disengaged from the second internal mobile 7.
- first magnetic zones 210 are arranged to cooperate, in the active position, in a complementary manner in axial attraction or repulsion parallel to the direction of the first axis D1 with the first internal mobile 1.
- the first internal mobile 1 comprises a plurality of radial arms 101, 102, defining, in projection on a plane perpendicular to the first axis D1, a particular geometric shape, and in the first magnetic zones 210 comprise a plurality of magnets 201 , 202, which are arranged radially around a second axis D2 according to this particular geometric shape, so as to produce an encoded magneto-mechanical connection specific to the single watch assembly 2000 considered.
- the first magnetic zones 210 comprise a plurality of magnets 201, 202, which are arranged radially around a second axis D2 along the direction in which their magnetic field axis extends, and which are in alternating polarity. .
- the first internal mobile 1 is ferromagnetic.
- the first internal mobile 1 comprises at least one magnet.
- the first ferromagnetic internal mobile 1 has a particular shape, which is arranged to minimize the effects of attraction, rotation or repulsion of a uniform external magnetic field of typically 1.5 Tesla, and to minimize the rotation of the first internal mobile 1, in particular ferromagnetic, under the action of a uniform external magnetic field of typically 1.5 Tesla.
- the first internal mobile 1 cannot be set in rotation with a single magnet, of any size and strength, by a user or by a repairer outside the manufacturer's network, who can at the limit engage the clutch, but not turn the first internal mobile 1.
- the first ferromagnetic internal wheel set 1 comprises a plurality of radial arms 101, 102, which extend radially up to the largest radius in which the first internal wheel set 1 is mobile around the first axis D1.
- element 2 is a component made of non-magnetic material, such as glass, sapphire, ceramic, an aluminum alloy, a titanium alloy, stainless steel, plastic. More particularly still, element 2 is an ice cream.
- the first internal mobile 1 is guided in pivoting around a first axis D1 by a shaft 4 or a bearing that comprises at least one watch 1000.
- At least one watch 1000 of the watch assembly 2000 is a non-magnetic watch. More particularly still, each watch 1000 of the watch assembly 2000 is a non-magnetic watch.
- At least one watch 1000 of the watch assembly 2000 is a non-magnetic watch. More particularly still, each watch 1000 of the timepiece assembly 2000 is a mechanical watch.
- At least one watch 1000 of the watch assembly 2000 is a non-magnetic watch. More particularly still, each watch 1000 of the watch assembly 2000 is an electromechanical or electronic watch.
- the second internal wheel set 7 is a wheel set for adjusting the rate of a regulating member that comprises at least one watch 1000.
- the second internal wheel set 7 is a time setting control wheel set for at least one watch 1000.
- the second internal wheel set 7 is an adjustment control wheel set for a calendar mechanism that includes at least one watch 1000.
- the second internal wheel set 7 is a winding control wheel set for at least one watch 1000.
- the second internal mobile 7 is an adjustment control mobile for an alarm and/or striking mechanism that comprises at least one watch 1000.
- the first internal mobile 1 is invisible to the user of at least one watch 1000.
- At least one watch 1000 is devoid of any external mechanical adjustment member passing through the casing of the watch 1000.
- At least one watch 1000 is impermeable to gases and to ambient humidity, and its casing comprises for this purpose at least one sealing zone capable of carrying out a metal or ceramic or glass sealing treatment under vacuum or in an inert gas atmosphere.
- At least one watch 1000 is sealed to be put under vacuum so as to be insensitive to variations in internal pressure caused by variations in temperature.
- At least one watch 1000 is equipped with an RFID chip or a passive identification means allowing direct identification after sales of the nature of the watch assembly 2000 to which the watch 1000 belongs, and of the adjustment tool 200 to be used.
- the non-limiting example illustrated by the figures 1 to 5 relates to such a watch assembly 2000, of which at least one watch 1000 comprises a first internal mobile 1, which here consists of a ferromagnetic cross, visible in plan on the figure 2 , internal to the casing, the case 10 here comprising a watch back crystal 2, as visible on the figure 1 , which represents the mechanism in section.
- This ferromagnetic cross 1 is pivotally mounted on a shaft 4 along the first axis D1, and is also capable of sliding axially along this first axis D1.
- the cross 1 is secured to a first drive element 3 which is a clutch pinion; a spring constitutes the elastic return means 5, visible in plan on the picture 3 in a particular embodiment of a spiral spring, and which keeps this clutch pinion away from its coupling position with a second internal mobile 7, which here comprises a plate driven and coupled, in the movement, to the function to be performed (the illustrated case is particularly well suited to adjusting the rate of a balance-spring by modifying the stiffness of said balance-spring).
- FIG 4 illustrates in plan the adjustment tool 200 specific to the 1000 watch family of the 2000 watch assembly.
- This adjustment tool 200 is here in a very simple variant provided with 4 magnets 201 and 202, distributed on the same radius around a second axis D2.
- the ferromagnetic cross 1 is attracted towards the crystal 2, in compression of the spring 5, and abuts against the crystal 2 at the end of the pivot.
- the driven board 7 is now engaged to the pinion 3.
- the rotation of the adjustment tool 200 causes, by reluctant effect on the branches of the ferromagnetic cross 1, a rotation of the internal stage.
- At least one watch 1000 comprises a first internal mobile 1, which here is irregular contour, and comprises in this example 5 arms unequally distributed angularly, and of variable radial amplitude; the corresponding adjustment tool 200 comprises 5 magnets, including 3 on the same radius, and 2 others on other radius values; among these 5 magnets, 4 have the same polarity to the first internal mobile 1, while a single magnet has the opposite polarity.
- This adjustment tool comprises a magnetic yoke arranged to face the first internal mobile.
- the cooperation between the first internal mobile 1 and the adjustment tool 200 can, to improve the inviolability of the system, act both on the geometry and on the combination of ad hoc polarities.
- the first internal mobile 1 can comprise point ferromagnetic zones and/or point magnets.
- the adjustment tool 200 can have any encoded shape.
- the first internal mobile 1 advantageously has, for its part, a rather compact shape, so as to minimize its magnetic positioning torque due to any external field.
- FIG 8 illustrates the cooperation (and withdrawal in the disengaged position with the representation of the pinion in dashed line) between the first internal mobile 1 and the adjustment tool 200 of the figures 6 and 7 , with alignment of the first axis D1 and the second axis D2.
- the looping of the magnetic fluxes through the ferromagnetic zones of the first internal mobile 1 and the magnets of the adjustment tool 200 is schematized by oriented closed loops, one in a solid line, the other in a broken line.
- the effective size of the system must remain small in relation to the main internal functions of the watch.
- the handling of the mechanism according to the invention must be reserved for factory production, or for a specialized shop, or for an after-sales service approved by the manufacturer, to avoid any problem of involuntary disruption by the customer or third parties.
- the cross and the key will therefore be sized to avoid any manipulation by a conventional magnet.
- the shape of the cross can be particular and complicated, hidden by an opaque layer or not, and cooperating with an ad hoc screwdriver which is difficult to find on the market, with a particular arrangement and dimensions of the magnets.
- the cross must not be able to orient itself during the application of a homogeneous external magnetic field of great intensity (a few Teslas), and, as far as possible, must move axially as little as possible.
- This system can also completely replace conventional pushers and stems, so as to produce automatic or other watches that are much more waterproof than the current ones.
