  • the watchmaker can intervene on the movement to make an adjustment of the state of charge of the spiral spring relatively easily, even when the movement works. Indeed, unlike the known mechanisms of the state of the art, it is not necessary to disassemble any element of the movement whatsoever to adjust the state of charge of the spiral spring.
  • the watch movement according to the invention is such that the adjustment wheel comprises a main shaft kinematically connected to the main energy source, a stop wheel integral with this shaft and carrying a fastening element integral with the first end of the spiral spring, the adjustment member, having the form of a shaft mounted coaxially and free to rotate relative to the main shaft and having a fastening element of the second end of the spiral spring, the second member, in the form of a drive wheel frictionally mounted on the adjustment member and kinematically connected to the time base.

  • main energy according to a predefined amplitude, via the main shaft and the stop wheel.
  • the adjustment member preferably has a circular periphery provided with a knurling or toothing forming the bearing surface, while the movement may comprise, in addition, a control mobile adjacent to the mobile of adjustment and comprising a pinion gear capable of cooperating with this bearing surface.
  • the toothed pinion is movable in translation between a first rest position, in which it is disengaged from the bearing surface, and a second adjustment position in which it meshes with the bearing surface.

  • the figure 2 represents a simplified top plan view of the watch movement of the figure 1 ;
  • the figure 3 represents a simplified sectional view of the watch movement according to the plane III-III of the figure 2 ;

  • Figures 5a and 5b represent simplified sectional views of the watch movement according to the IV-IV plane of the figure 2 in respective first and second configurations.
  • a watch movement consisting essentially of conventional constituent bodies has been illustrated on the Figures 1 to 3 , in particular a barrel 1 housing a barrel spring (not visible) and intended to feed the mechanical oscillations of a time base of which only the escape wheel 2 has been shown.
  • the energy of the mainspring is transmitted via a finishing gear comprising a center wheel 4 whose pinion 5 is engaged with the toothing of the barrel drum and whose wheel 6 is engaged with the pinion. 8 of a moving average 9.
  • the wheel 10 of the average mobile is in turn engaged with a pinion 12 of a first mobile seconds 13 whose wheel 14 is in engagement with the exhaust pinion 16.
  • the watch movement according to the present invention comprises a constant force device for transmitting a constant force to the time base from the force it receives from the mainspring which varies significantly according to the arming of the latter.
  • the constant force device comprises in particular a secondary spring 18 preferably having the shape of a spiral spring. It is mounted on the mobile of average 9 with a first of its ends, internal, integral with an adjustment member 20, whose operation will be described later, mounted free to rotate on the shaft of the mobile average 9 and carrying the wheel of average 10.
  • the second end, external, of the spiral spring 18 is secured to a stop wheel 22 via a stud 23, the stop wheel being integral in rotation with the average mobile tree 9.
  • the constant-force device also comprises a second second wheel 24 whose wheel 25 meshes with the wheel 14 of the first seconds wheel 13, in a 1/1 ratio by way of nonlimiting illustration.
  • the shaft of the second seconds mobile 24 carries a cam 26 with five bumps 28, integral with the rotating shaft.
  • the cam 26 here performs a turn on itself in sixty seconds.
  • the cam 26 cooperates with a first fork 30 of a control anchor 31 pivotally mounted on a frame member of the movement (not visible) between two extreme positions.
  • the control anchor 31 comprises a second fork 32 arranged to cooperate with sawtooth teeth of the stop wheel 22.
  • the second fork carries two pallets 34 and 35 arranged in such a way that, when the anchor pivots, one of the pallets being in contact with the toothing of the stop wheel 22, this pallet is disengaged from the toothing thus releasing the stop wheel which rotates here by twelve degrees (because the toothing has thirty teeth by way of non-limiting illustration) before another tooth abuts on the other pallet which, meanwhile, has positioned itself within reach of the toothing of the stopping wheel 22.
  • the pallets ensure the locking of the stopwheel alternating, the latter advancing one step each time from one pallet to another.
  • the period of the alternations can also be adjusted by the choice of the shape of the cam 26, in particular the number of its bumps 28.
  • each complete revolution of the cam 26 on itself causes ten pivoting of the anchor 31.
  • the stop wheel 22 is released every six seconds.
  • the spiral spring 18 Based on the principle that the spiral spring 18 has a non-zero state of load, the mechanical oscillator (a conventional balance spring, for example) being in oscillation mode, the spiral spring transmits a portion of its mechanical energy to the mechanical oscillator via the average wheel 10, the first seconds mobile 13, the exhaust pinion 16 and the escape wheel 2.
  • the mechanical oscillator a conventional balance spring, for example
  • the anchor 31 pivots under the effect of its cooperation with the cam 26 and releases the stop wheel 22, secured to the shaft of the average mobile 9, the latter being kept under tension by the barrel spring, via the center wheel 4.
  • the stop wheel 22 then rotates twelve degrees, as explained above, driving with it the bolt 23 and therefore the outer end of the spring- spiral 18 (in the direction of the arrow indicated on the figure 2 ).
  • the latter is thus recharged every six seconds by a relative displacement between its inner ends - fixed at the release of the stop wheel 22 - and external at an angle of twelve degrees.
  • the gears of the gear train are preferably chosen such that the average wheel 10 travels at an angle of twelve degrees during the six seconds separating two successive loads spiral spring 18, that is to say say that this wheel performs a complete turn on itself in three minutes. Thanks to these characteristics, the spiral spring 18 accumulates each time a quantity of energy from the mainspring corresponding to the spring that it transmitted to the mechanical oscillator of the movement during the previous six seconds.
  • the movement according to the present invention proposes a mechanism for adjusting the state of charge of the secondary spring, easy to access and use, which will now be described in connection with the figures 4 , 5a and 5b .
  • the figure 4 represents the average mobile 9 according to the invention in a cross-sectional view taken along the same sectional plane as the figure 3 , namely according to plan III-III of the figure 2 .
  • the stop wheel 22 is rotationally fixed to the shaft of the average mobile 9, formed in one piece with the pinion of average 8.
  • the adjustment member 20 carrying the inner end the spring-spiral 18 is mounted free on the shaft of the average mobile 9 and carries the average wheel 10.
  • the adjustment member 20 acts on the adjustment member 20 by its inner end, its outer end being held fixed by the stop wheel 22, for rotate the wheel of average 10 and maintain oscillations of the mechanical oscillator.
  • the state of charge of the spiral spring 18 can be adjusted by changing the relative angular positions of its two ends at a given moment.
  • the Applicant has had the idea of providing friction at the level of the connection between the adjustment member 20 and the average wheel 10. This friction is achieved in such a way that the adjustment member causes the average wheel during the running operation of the movement, while allowing to turn the adjustment member on itself when the average wheel is held fixed by the exhaust.
  • a rotation of the adjustment member clockwise on the view of the figure 2 thus causes a decrease in the tension of the spiral spring 18 while a rotation in the counterclockwise direction causes an increase in its tension.
  • the adjustment member in the form of a shaft integral with a board 40 provided with a peripheral toothing 41, defining a bearing surface on which it is possible to act to turn the adjustment member on itself more easily.
  • a control mobile 42 is also provided in a position adjacent to that of the average mobile 9, the latter having a pinion toothed 44 arranged to cooperate with the toothing 41 of the adjustment member to rotate the latter.
  • the pinion gear 44 is not in permanent engagement with the adjustment member to limit the friction losses of the watch movement, as is more clearly apparent from the Figures 5a and 5b .
  • the control mobile 42 is pivotally mounted and free in translation on a fixed foot 46 on an element of the frame 47 of the movement, such as the plate, the foot being disposed inside a hollow shaft of the control mobile.
  • a helical spring 48 is disposed between the control mobile and the frame member 47 tending to maintain the control mobile in a remote position with reference to the frame. In this position, represented on the figure 5a the toothed gear 44 is not engaged with the toothing 41 of the adjustment member 20.
  • control mobile 42 is advantageously provided with a slot 50 adapted to manipulation with a tool, such as a screwdriver, to further facilitate the adjustment of the state of charge of the spring- spiral 18 and therefore the amplitude of the oscillations of the mechanical oscillator of the watch movement.
  • a tool such as a screwdriver
  • the watch movement according to the present invention further comprises a safety device to prevent inadvertent discharge of the spiral spring 18, in particular when the mainspring is discharged almost completely to the point of no longer having sufficient energy to recharge it.
  • a safety device to prevent inadvertent discharge of the spiral spring 18, in particular when the mainspring is discharged almost completely to the point of no longer having sufficient energy to recharge it.
  • the spiral spring is discharged almost completely while continuing to feed the oscillations of the mechanical oscillator once the barrel spring is too discharged to be able to recharge it. It is then necessary to access the movement to reset the spiral spring 18 with a suitable tension to ensure a good accuracy of movement, which is very restrictive. To avoid this situation, the user of a watch equipped with such a mechanism must ensure that the mainspring is never fully discharged.
  • the average wheel 10 has a particular shape, visible on the figure 2 through the adjustment member 20, represented in transparency: the hub and the serge of the average wheel are connected to one another by means of double arms 100 whose function is to ensure the connection by friction with the shaft of the adjustment member.
  • the serge of the wheel of medium 10 also carries an addition of material 101 arranged in the plane of the serge and having a housing 102 inside which is disposed the peak 23 carrying the outer end of the spiral spring 18.
  • the housing 102 is arranged such that it has an angular aperture substantially equal to or slightly greater than the stroke made by the pin when the stop wheel 22 or the average wheel 10 rotates twelve degrees. The housing 102 thus defines stops to movements of the piton in one direction and the other.
  • the peak 23 is close to a first edge of the housing 102 when the spiral spring 18 has just been reloaded, while the average wheel 10 runs for the next six seconds, such that the peak 23 is close to the other edge of the housing 102 after six seconds. If at the moment of the next charge the barrel spring no longer has enough energy to recharge the mainspring, the bolt 23 does not return towards the first edge and thus quickly forms a stop for the edge of the housing located at side of it, blocking the rotational motion of the average wheel, which causes a stop of the movement, then, gradually a stop oscillations of the mechanical oscillator.
  • the spiral spring 18 still retains its initial state of charge, namely that which has been attributed to it during the adjustment of the movement by the manufacturer, relieving the user of the corresponding watch which is not forced to monitor the state of charge of the mainspring as in the case of movements of the state of the art.
  • the stud 23 carrying the outer end of the spiral spring 18 is disposed directly between two arms 100 of the same pair, the latter thus forming stops to the movements of the pin in one direction and in the other.
  • the spacing between the two arms of a pair is such that it is substantially equal to or slightly greater than the stroke made by the pin when the stop wheel 22 or the average wheel 10 rotates twelve degrees.
  • the period separating two successive loads of the spiral spring may also be modified without departing from the scope of the invention, to be for example equal to ten, twelve or even twenty seconds.
  • the principle of the present invention is not limited to a frictional implementation at the location indicated in the description.
  • the invention more generally relates to a watch movement comprising a constant force device, comprising a spiral spring, and a gear train having a first drive train arranged to connect a main power source to a first end of the hairspring spring, and a second drive train to connect a time base to a second end of the hairspring spring, one or the other of the first and second kinematic chains comprising an adjustment wheel comprising first and second members connected to one another by a friction such that a rotation of one causes the other during the current operation of the watch movement, one of these members being an adjustment member having at least one bearing surface arranged in such a way that it is possible to act on it to rotate the adjustment member without rotating the other member , because of the friction, in order to adjust the state of charge of the spiral spring.
  • the average wheel 10 is rigidly connected to the adjustment member 20, which would then no longer be an adjustment member, a friction being provided alternately between the wheel 14 of the first mobile of seconds 13 and the pinion 12 of this mobile.
  • the state of charge of the spiral spring could be adjusted by action on the pinion 12 of the first seconds mobile 13, when the wheel 14 is held fixed by the exhaust.
  • the stop wheel 22 on the center wheel 4, making it integral with the shaft, thus the center pinion 5.
  • the center wheel 6 can be mounted friction on the shaft and be actuated to adjust the state of charge of the spiral spring 18.
  • Specific additional wheels may also be provided alternatively.
  • the invention is also not limited to the particular embodiment described with regard to the bearing surface for actuating the adjustment member. It is of course conceivable to surface adapted to cooperate with a tool directly on the adjustment member 20, for example, without departing from the scope of the invention.
