Definitions

  • the present invention relates to a timepiece, more particularly the mechanism for measuring and displaying the operating energy stored in a watch.
  • winder Mechanical watches with manual winding must have a winding system, called winder. It is through this device that manually transmits energy to the barrel, energy accumulator of the shows. The watch winder is also used for other functions such as resetting the time or changing the date.
  • the object of the present invention is to propose a device for indicating power reserve for watches with double barrels, both those with manual winding, than those with automatic winding.
  • a power reserve device comprising two barrels, one known as armament and the other known as disarming, a solid star wheel display means, characterized in that the winding barrel comprises a winding pin actuating a winding lever driving in rotation positive the star wheel, the disarming barrel includes a pin disarming actuating a disarming lever causing negative rotation the star wheel, the latter being held in its position by a jumper.
  • the present invention applies firstly to watches equipped with two barrels.
  • the special feature of the double barrel mechanism is that during the arming, only one barrel is in rotation, the second remaining stationary. Conversely, during disarming, the second barrel is in rotation while the first remains motionless.
  • the winding is done by turning the winding crown, the pinion sliding being in its gear position with the winding pinion. This last meshes with the crown wheel itself driving the ratchet (fixed on the disarming barrel shaft).
  • the barrels are thus armed and execute their primary function namely: to store the energy necessary for watch operation.
  • a winding pin has been fixed on the barrel winding. According to the rotational movement of this barrel, the said pin enters in contact with a lever whose tilting at its opposite end, will activate the star wheel on which the display is located.
  • the reassembly is carried out using an oscillating mass, whose rotation is ensured by arm movements and through a combination of pawls and cogs, and arms the spring.
  • the barrel is thus armed and performs its primary function namely: to store the energy necessary for watch operation.
  • a winding pin has been fixed on the barrel winding. According to the rotational movement of this barrel, the said pin enters in contact with a lever whose tilting, at its opposite end, activates the star wheel on which the display is located.
  • the two levers, the winding lever and the disarming lever, are disengaged from the star wheel by return springs. This allows to leave free the star wheel for the action of the lever which is being tilted.
  • a jumper resting on the star wheel guarantees that the star stays in place in the position defined by the action of the levers.
  • Each of the levers is mounted on a pivot axis, one of the sides being positioned opposite the toothing of the star wheel, the other side being placed in look of the barrel pin.
  • FIG. 1 describes the part specific to the arming of the barrels with its mechanism driving an indication wheel (star wheel) 3 by a winding lever 4.
  • a first lever, said winding lever 4, is mounted on a pivot axis 11 secured to a bridge not shown.
  • One end of this lever 4 has a pin 14, the other end being terminated by a lug 13 of function drive.
  • This winding lever 4 is held in its rest position by a return spring 6 pressing on the pin 12, said spring having as a function of returning the winding lever 4 to its rest position, that is to say outside the circumference of the star wheel 3.
  • the impulse given by the pin 14 allows the rotation of the star wheel of a tooth in the positive direction (arming direction).
  • the winding barrel 1 has a winding pin 9 placed on the periphery of the barrel 1. At each turn of this barrel, the winding pin 9 drives the lug 13 of the winding lever 4, said lever coming by pivoting, engage the toothing of the star wheel 3 using the pin 14 drive.
  • the disarming lever 5 comprises at one of its ends a lug 15 shown in dotted lines in the figure, driven by a disarm pin 10 secured to the disarming barrel 2. At each rotation of this barrel 2, the lever disarming 5 rocks around its pivot axis 11 and causes the star wheel 3 of a tooth in the so-called negative direction (disarming direction).
  • This disarming lever 5 is held in its rest position by a return spring 7 pressing by means of a pin 16, said spring having the function of returning the disarming lever 5 to its position rest, i.e. outside the circumference of the star wheel 3.
  • the function of the jumper 8 is on the one hand to guarantee the maintenance of the star wheel 3 in its position of indication and on the other hand to participate in the tilting.
  • the jumper 8 allows the stroke of a tooth to be ended.
  • Figure 3 shows a top view of the complete mechanism with its two levers. These are mounted on the same axis 11 and we can observe the dual function of arming and disarming.
  • Figure 4 is a section of the assembly along a plane determined by the axes of barrels and star wheel.
  • the axis of the star wheel 3 is integral with the means display of the power reserve, in our case a graduated drum 17. This the latter, through a window serving as a fixed reference, will indicate the reserve of watch running.
  • the location of the pins on the barrels is not important in itself, whether either on the barrel board as illustrated on the disarming barrel 2, or on the drum as illustrated on the winding barrel 1.
  • FIG. 5 represents a variant of the invention with the two barrels mounted on the same plane.
  • the system of the invention also applies in this case, the main difference is that each lever has its own own axis, ie 11 'and 11 ".
  • the number of pins per barrel can be greater than one depending on the display mode chosen. Indeed, if the number of teeth of the star wheel is important, it may be desirable to cause the training of two teeth per barrel turn.
