Definitions

  • the present invention relates to a switching device of a clock mechanism between two functional states.
  • the present invention relates to a timepiece comprising a mechanism that can switch between a first state and a second state, a switching device of this mechanism and an actuating device of this switching device.
  • the switching device comprises a control member actuated by the actuating device and a switching member that can be placed on command from a first stable position, for which the mechanism is in its first state, to a second stable position, for which mechanism is in its second state, and vice versa.
  • the invention relates to a device for clutching a mechanism of a mechanical watch movement.
  • the patent application EP 2 897 003 discloses a conventional clutch device for a chronograph mechanism.
  • This clutch device comprises an intermediate wheel which, when the clutch is engaged (device in the engaged state), meshes simultaneously with a chronograph wheel and a driving wheel and which, when the clutch is tripped (device in disengaged state), is removed from at least one of these two wheels to break the kinematic chain between them.
  • the clutch device comprises a clutch rocker which carries the intermediate wheel at the end of one of its two arms and which is associated with a first return spring so that the end of the second arm of this clutch rocker remains in support against a column wheel.
  • the column wheel thus forms a kind of cam and the aforementioned end of the clutch rocker forms a cam follower.
  • a large rocker which carries at one end a pivoted ratchet and associated with a second return spring.
  • the conventional clutch mechanism described above is complex. It comprises several rotated members including a column wheel which is a complex piece and therefore relatively expensive.
  • the two aforementioned springs generate frictional forces in the areas of mechanical contact provided, which generate wear.
  • such springs are fragile and may have an elasticity that varies with age.
  • the various members must be precisely mounted in the timepiece to be functional, including the operating ratchet of the column wheel and the large rocker that causes the reciprocating movement of the pawl.
  • the object of the present invention is to propose a device for switching a watch mechanism of a type different from the aforementioned conventional device and which eliminates several disadvantages of such a conventional device.
  • the control member is arranged such that, when actuated repeatedly by the actuating device, the first high-magnetic-permeable element is reciprocated (reciprocating) between a first position control and a second control position.
  • the switching device is arranged in such a way that, when the first high magnetic permeability element is in its first control position, the first and second magnets generate between them a magnetic repulsion force over substantially the whole of the switching path and so that when the first element with high magnetic permeability is in its second control position, the first and second magnets generate between them a magnetic attraction force on at least a part of the switching path, this part being located on the side of the second bipolar magnet.
  • a spring of relatively low return force is provided in addition to the magnetic switching device to participate in the displacement of the switching member in one direction and / or help maintaining this switching member in one of its stable positions.
  • a spring can act on the switching member for, when the first element with high magnetic permeability is in its second control position, move this switching member on a first part the switching path located on the side opposite the second bipolar magnet, until the magnetic attraction force intervenes to attract the switching member towards the second bipolar magnet.
  • the repulsive magnetic force has an intensity and a range that are sufficient for it to operate alone the switching member between its first stable position and its second stable position and then maintain it in this second position. stable position; while the magnetic attraction force has an intensity and a range that are sufficient for it to operate alone the switching member between its second stable position and its first stable position and then maintain it in this first stable position.
  • the magnetic switching device defines a bistable system. Moreover, in the preferred embodiment, mentioned above, this device for switching does not require any return spring associated with the switching member.
  • the control member is formed by a rocker pivoted so that the high magnetic permeability element undergoes a rotational movement between two determined angular positions when the control rocker is actuated.
  • a rocker is a simpler piece to achieve a column wheel.
  • the control rocker is pivoted so that the first high magnetic permeability element is rotated between a first angular position and a second angular position respectively defining the first control position and the second control position. Then, when the first element with high magnetic permeability is in its second angular position, this first element is substantially located on an alignment axis defined by the magnetic axis of the second bipolar magnet so that it is substantially between the first and second and second bipolar magnets.
  • the first element with high magnetic permeability is spaced from the aforementioned alignment axis.
  • control lever does not require a pawl pivoted and associated with a return spring. It will also be noted that the magnetic system makes it possible to avoid any contact between the control member and the switching member.
  • the switching path of the first bipolar magnet is substantially coincident with the alignment axis defined by the magnetic axis of the second bipolar magnet and this first bipolar magnet is arranged with its magnetic axis substantially oriented along this axis. alignment, the first and second bipolar magnets being arranged with their polarities opposite.
  • the magnetic system 2 comprises a first fixed magnet 4, a high magnetic permeability element 6 and a second magnet 8 which is movable along an axis of displacement here confused with the alignment axis 10 of these three magnetic elements, relative to the assembly formed by the first magnet 4 and the element 6.
  • This element 6 is arranged between the first magnet and the second magnet, close to the first magnet and in a specific position relative thereto.
  • the distance between the element 6 and the magnet 4 is less than or substantially equal to one-tenth of the length of this magnet along its axis of magnetization.
  • the element 6 is constituted for example of a carbon steel, tungsten carbide, nickel, FeSi or FeNi, or other alloys with cobalt as the Vacozet ® (CoFeNi) or Vacoflux ® (CoFe).
  • this element with high magnetic permeability consists of a metal glass based on iron or cobalt.
  • Element 6 is characterized by a saturation field Bs and a permeability ⁇ .
  • the magnets 4 and 8 are for example ferrite, FeCo or PtCo, rare earths such as NdFeB or SmCo. These magnets are characterized by their remanent field Br1 and Br2.
  • the element with high magnetic permeability 6 has a central axis which is preferably substantially coincidental with the magnetization axis of the first magnet 4 and also with the magnetization axis of the second magnet 8, this central axis being here confused with the alignment axis 10.
  • the respective magnetization directions of the magnets 4 and 8 are opposite. These first and second magnets therefore have opposite polarities and they are likely to undergo relative movement between them over a certain relative distance.
  • the distance D between the element 6 and the movable magnet 8 is indicated in Figures 1 and 2 .
  • the axis 10 is provided here linear, but this is a non-limiting variant.
  • the axis of displacement can also be curved, as in the embodiment which will be described later.
  • the central axis of the element 6 is preferably approximately tangent to the axis of curved displacement and thus the behavior of such a magnetic system is, in a first approximation, similar to that of the magnetic system described here. .
  • the radius of curvature is large relative to the maximum possible distance between the element 6 and the movable magnet 8.
  • the element 6 has dimensions in a plane orthogonal to the central axis 10 which are greater than those of the first magnet 4 and those of the second magnet 8 in projection in this orthogonal plane.
  • the second magnet advantageously comprises a cured surface or a thin layer of hard material on its surface.
  • the two magnets 4 and 8 are arranged in magnetic repulsion so that, in the absence of the element with high magnetic permeability 6, a magnetic repulsion force tends to move these two magnets away from each other. Surprisingly, however, the arrangement between these two magnets of the element 6 reverses the direction of the magnetic force exerted on the moving magnet when the distance between this movable magnet and the element 6 is sufficiently small, so that the moving magnet then undergoes a magnetic attraction force.
  • Curve 12 of the Figure 2 represents the magnetic force exerted on the movable magnet 8 by the magnetic system 2 as a function of the distance D between the movable magnet and the element with high magnetic permeability 6.
  • the moving magnet undergoes, on a first range D1 of the distance D, globally a magnetic attraction force which tends to maintain the magnet 8 against the element 6 or to bring it back towards the latter in the event of removal, this overall force of attraction resulting from the presence of the element with high magnetic permeability (In particular ferromagnetic) which allows a reversal of the magnetic force between two magnets arranged in magnetic repulsion.
  • the element 6 and the two magnets are arranged so that the second magnet 8 undergoes, on a second range D2 of the distance D, globally a magnetic repulsion force.
  • This second range corresponds to distances between the element 6 and the magnet 8 which are greater than the distances corresponding to the first range of the distance D.
  • the second range is limited by a maximum distance D max which is generally defined by a stop limiting the distance of the moving magnet.
  • the magnetic force exerted on the moving magnet is a continuous function of the distance D and it therefore has a value of zero at the distance D inv for which this magnetic force is inverted.
  • the inversion distance D inv is determined by the geometry of the three magnetic parts forming the magnetic system and by their magnetic properties. This inversion distance can therefore be selected, to a certain extent, by the physical parameters of the three magnetic elements of the magnetic system 2 and by the distance separating the fixed magnet from the ferromagnetic element. It is the same for the evolution of the slope of the curve 12, the variation of this slope and in particular the intensity of the attractive force when the moving magnet approaches the ferromagnetic element can thus be adjusted .
