Definitions

  • the invention relates to a clockwork power reserve indicator mechanism, for displaying the power reserve of the energy storage means of a clockwork movement, which energy storage means are arranged to be powered in the winding phase by an entry wheel actuated by a stem that comprises said movement or by an automatic winding mechanism that comprises said movement or by an external crown, and are arranged to restore energy to said movement in phase disarming by an output wheel, said mechanism comprising at least one display mobile arranged to be driven indirectly by said input wheel or by said output wheel, said mechanism comprising a differential mechanism including said input wheel and said output wheel constitute two inputs, and comprising, at a single output, an output mobile which is arranged to directly or indirectly drive said display mobile.
  • the invention also relates to a timepiece movement comprising at least one such mechanism.
  • the invention also relates to a watch comprising at least one such clock movement, and/or at least one such mechanism.
  • the invention relates to the field of clockwork mechanisms, and the management of the energy storage of such mechanisms, in particular the display of the remaining power reserve at the motor means.
  • the display of the power reserve on a mechanical watch is a useful function, making it possible to prevent any untimely stopping of the watch for lack of energy, which could oblige the user to update calendar mechanisms, or similar, which is always tedious, and which also makes it possible to maintain the level of energy stored in a range where the torque delivered is substantially constant, thus allowing optimum chronometry.
  • This function cannot always be positioned at will in the watch case, because it is dependent on the position of the energy transmission cogs, and it is often difficult, in the case of a calendar watch or a complication watch, to position all the displays in the best possible way, with the minimum of references, which consume space and energy.
  • the document EP2977828 in the name of ETA Manufacture Horlogère Suisse describes a watchmaking power reserve indicator for displaying the power reserve indication of a plurality of energy accumulators each comprising an indicator cooperating with an input of a differential mechanism which the indicator comprises power reserve, and of which an output of the differential mechanism cooperates with a mechanism for displaying the total power reserve of the plurality of energy accumulators, and at least two inputs are coaxial.
  • the document EP1970778 in the name of MONTRES BREGUET describes a timepiece which comprises a power reserve indicator device with a differential frame which is arranged coaxially with respect to a barrel arbor.
  • the secondary output of the differential is attached to a cover.
  • the differential gear output is obtained by an inner ring gear which is kinetically connected to the primary input by the planet wheels meshed with each other and carried by the cover.
  • the invention proposes to provide a simple, compact mechanism which allows the designer to place a power reserve indicator in any available place of a watch.
  • the invention relates to an operating indicator mechanism according to claim 1.
  • the invention also relates to a timepiece movement comprising at least one such mechanism.
  • the invention also relates to a watch comprising at least one such clock movement, and/or at least one such mechanism.
  • the invention relates to a clockwork power reserve indicator mechanism 100, for displaying the power reserve of energy storage means 200 of a clockwork movement 300.
  • These energy storage means 200 are arranged to be powered during the winding phase by an input wheel 2.
  • This input wheel 2 is actuated by a stem 1 which the movement 300 includes. , or by an automatic winding mechanism 400 included in the movement 300, or even by an external winding mechanism.
  • the energy storage means 200 are arranged to restore energy to the movement 300 in the disarming phase by an output wheel 14.
  • Mechanism 100 includes at least one display mobile 10 or 12, arranged to be driven indirectly by input wheel 2 or by output wheel 14.
  • the mechanism 100 comprises a differential mechanism 30 whose input wheel 2 and output wheel 14 constitute two inputs, and comprising, at a single output, an output mobile 7 which is arranged to directly or indirectly drive the mobile display 10 or 12.
  • the differential mechanism 30 is a ball and friction differential mechanism, comprising a first plate 3 meshing directly or indirectly with the input wheel 2, and a second plate 16 parallel to the first board 3 and meshing directly or indirectly with the output wheel 14.
  • This differential mechanism 30 further comprises balls 5 which are arranged to roll between the first board 3 and the second board 16, under the action of friction means 4 which are arranged to push the first board 3 and the second board 16 towards each other, driving during their rolling a basket 6 in which the balls 5 are enclosed and which is arranged to drive the output mobile 9.
  • first board 3 and the second board 16 are coaxial.
  • first board 3 and the second board 16 are coaxial with the basket 6 which is secured to the output wheel set 9, which is secured to a shaft 7 carrying the first board 3 and the second board 16.
  • the friction means 4 comprise at least one elastic element resting, on the one hand, on a plate 20 or a bridge 21 or 22 that comprises the mechanism 100 or the movement 300, and on the other hand on the first board 3 in the variant of the figures, or on the second board 16.
  • the figure 1 shows these friction means 4 in the form of a left-hand spring resting on the barrel bridge 21.
  • a washer 17 driven onto the differential shaft 7, which carries the basket 6 and the output mobile 9 for driving the mobile display 10 or 12.
  • the first board 3 and the second board 16 pivot around this shaft 7. This washer 17 holds the spring 4, and makes it possible to hold the balls 5 in their basket 6, between the first board 3 and the second plate 16.
  • the mechanism 100 comprises a first mobile display visible on a first side of a plate 20 or of a bridge 21 or 22 that comprises the mechanism 100 or the movement 300, and a second mobile display visible on a second side opposite the first side.
  • a mobile display is a display wheel 12, which is driven directly or indirectly by a toothed ring 10 which meshes with the output mobile 9, and the pivot axis of this display wheel 12 is inside or outside the ring 10 inside which the mobiles that comprise the differential mechanism 30 pivot.
  • the figures 6 to 9 show an internally and externally toothed ring, which allows the manufacturer to choose the position of a display wheel 12 outside this ring as on the figure 6 , or inside this ring as on the figures 7 to 9 .
  • the display wheel 12 comprises a loop 120 which cooperates with a pin 121 which is fixed on a plate 20, or on such a bridge 21 or 22, to limit the angular travel of the display wheel 12 which is pivoted by its shaft 23 between plate 20 and a bridge 22 or a dial 40.
  • a display mobile is directly constituted by a toothed ring 10 which meshes with the output mobile 9, inside which ring 10 pivots the mobiles that comprise the differential mechanism 30. More particularly, this display mobile constitutes a power reserve display, and this ring 10 advantageously bears a progressive marking 101 on at least one of its flat surfaces, contrasting with a clear background 102, arranged to allow the visualization of the remaining power reserve in an aperture 41 of a dial 40.
  • a timepiece movement 300 comprises at least one dial 40, one plate 20 and at least one bridge 21 or 22, arranged to support the differential mechanism 30, and comprising a plurality of layouts each capable of receiving a display wheel 12 according to the first variant, in different angular positions of the dial 40. It is thus very easy to arrange, at will, a power reserve indicator on any zone of the dial.
  • the movement 300 comprises a plate 20 and at least one bridge 21 or 22, arranged to support the differential mechanism 30, and the dial 40 comprises an aperture 41 for viewing the progressive marking 101 .
  • the invention is applicable to the display of the power reserve of energy sources specific to the movement, but also to ancillary functionalities such as a striking mechanism, or a music box, or other.
  • the invention also relates to a watch 1000 comprising at least one such movement 300, and/or at least one such mechanism 100 power reserve indicator.
  • This construction offers the possibility of easily displaying the power reserve over 360°, in any appropriate zone of the dial or of the movement of the watch.
