Definitions

  • the present invention relates to a timepiece, more particularly to 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 a winder. It is through this device that energy is manually transmitted to the barrel, the watch's energy accumulator. The winder is also used for other functions such as resetting the time or changing the date.
  • the object of the present invention is to provide a power reserve indication device for watches with double barrels, both those with manual winding and those with automatic winding.
  • a power reserve device comprising two barrels, one called winding and the other said disarming, a star wheel secured to a display means, characterized in that the barrel armament comprises a winding pin actuating a winding lever driving in positive rotation the star wheel, the disarming barrel comprises a disarming pin actuating a disarming lever driving in 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 peculiarity of the double barrel mechanism lies in the fact that during winding, only one barrel is in rotation, the second remaining stationary. Conversely, during disarming, the second barrel is in rotation while the first remains stationary.
  • the great autonomy of the double barrel system makes it useful to have a power reserve display. For this we use the existing mechanism of double barrels with the addition of two levers. The addition of the power reserve indication mechanism will affect the barrels as well as the display.
  • the winding is carried out by turning the winding crown, the sliding pinion being in its gear position with the winding pinion.
  • the latter meshes with the crown wheel itself driving the ratchet (fixed on the disarming barrel shaft).
  • the barrels are thus armed and perform their primary function, namely: storing the energy necessary for the operation of the watch.
  • a winding pin has been attached to the winding barrel. According to the rotational movement of this barrel, said pin comes into contact with a lever, the tilting of which at its opposite end, will actuate the star wheel on which the display is located.
  • the reassembly is carried out using an oscillating mass, whose rotation is ensured by the movements of the arm 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 attached to the winding barrel. According to the rotational movement of this barrel, said pin comes into contact with a lever whose tilting, at its opposite end, actuates 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 the star wheel to be left free for the action of the lever which is being tilted.
  • a jumper resting on the star wheel guarantees that it remains 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 opposite the pin of the barrel.
  • FIG. 1 represents a charge reserve indicator with its winding mechanism
  • FIG. 2 represents a charge reserve indicator with its disarming mechanism
  • FIG. 3 represents a top view illustrating the two arming and disarming mechanisms
  • Figure 4 shows, in section, the charge reserve indicator with its positive / negative rotation mechanism and two superimposed barrels.
  • FIG. 1 describes the part specific to winding the barrels with its mechanism for 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 the drive function.
  • This winding lever 4 is held in its rest position by a return spring 6 pressing on the pin 12, said spring having the function of returning the winding lever 4 to its rest position, that is to say 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 (winding 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 in the toothing of the star wheel 3 by means of the drive pin 14.
  • the disarming lever 5 comprises at one of its ends a lug 15 shown in dotted lines in the figure, driven by a disarming pin 10 secured to the disarming barrel 2. At each rotation of this barrel 2, the disarming lever 5 rocks around its pivot axis 11 and drives 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 rest position, it is 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. Indeed, at each pulse either of the winding pin 14, or the end of the disarming lever 5, 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 the barrels and the star wheel.
  • the axis of the star wheel 3 is integral with the means of displaying the power reserve, in our case a graduated drum 17. The latter, through a window serving as a fixed reference, will indicate the power reserve of the watch.
  • the location of the pins on the barrels is not important in itself, whether on the barrel board as illustrated on the disarming barrel 2, or on the drum as illustrated on the cocking barrel.
  • 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 residing in the fact that each lever has its own axis, ie 1 V and 11 ".
  • the load reserve indication marks in this case being fixed on a dial.
  • 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 large, it may be desirable to cause the drive of two teeth per barrel revolution.
