Definitions

  • the present invention relates to a power reserve indicator device arranged to be integrated in an oscillating weight for self-winding movement, said device comprising means for displaying the power reserve in comparison with complementary display means, said means display and complementary display means being integrated in said oscillating weight.
  • the invention also relates to an oscillating weight for a self-winding watch, comprising such a power reserve device.
  • the invention also relates to a self-winding watch comprising an oscillating weight whose movements are transmitted to a mainspring of said watch, said oscillating mass comprising such a power reserve indicator device.
  • the invention relates to the field of self-winding watches.
  • the movements of the wearer are transmitted to the mainspring by means of an oscillating weight and a reduction gear train.
  • the gear of an automatic winding mechanism consists of toothed elements that transmit the force from the oscillating mass to the ratchet and arm the barrel spring. Upstream of the ratchet, this wheel of automatic winding mechanism usually comprises, on the one hand, a gear train composed of the pinion of the mass oscillating and intermediate rectifiers sense, and secondly a gear train, arranged to reduce the initial speed of the oscillating weight and increase the force for winding the mainspring.
  • a useful and appreciated complication on self-winding watches is the display of the power reserve, which is provided by a power reserve indicator device, allowing the user at any time to know the normal walking potential, in the best conditions of reliability and precision of the mainspring.
  • the power reserve is indicated either by a graduated, encrypted or graphic indication on a disc visible through a window, or by the positioning of a needle facing a dial bearing such an indication.
  • the indication of the power reserve must be compatible with the small space still available in a timepiece with several complications. Its reliability must be exemplary, and in particular to dissuade the user from performing a manual winding complement even though the mainspring is already fully armed.
  • the patent document CH 301 497 discloses a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, this watch also comprising a reserve indicator device of step comprising means for displaying the power reserve.
  • a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, this watch also comprising a power reserve indicator device comprising means for displaying the power reserve, which are mounted on the oscillating weight.
  • the invention proposes to provide a solution to the problem of producing a mechanism for displaying the power reserve integrated with the oscillating weight, which is reliable, simple to implement, and of great robustness.
  • the present invention relates to a power reserve indicator device arranged to be integrated in an oscillating weight for self-winding movement, said device comprising means for displaying the power reserve compared with display means.
  • said display means and complementary display means being integrated in said oscillating mass, characterized in that said display means and complementary display means are mounted movably in synchronous rotation, at a given instant, with respect to said oscillating weight.
  • said display means and complementary display means are rotatably mounted relative to a common axis of rotation.
  • said device comprises a differential friction display mechanism with two inputs, one fixed and the other mobile, and an output constituted by a display member comprising said means for display and complementary display means, said moving input driving said display means, and said fixed input driving said complementary display means by disengageable drive means.
  • said complementary display means comprise a stop, on which said display means are arranged to cooperate in support in a so-called end-of-arming position, and in that said fixed input co-operates with a disengageable coupling, which is engaged with said complementary display means when said display means are not supported on said stop, and which is disengaged from said complementary display means when said display means are supported on said stop.
  • said so-called end of winding position corresponds to the end of winding of a barrel spring to which said movable inlet is connected by means of a gear train.
  • the invention also relates to an oscillating weight for a self-winding watch, comprising such a power reserve device.
  • the invention also relates to a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, said oscillating weight comprising such a power reserve indicator device.
  • the present invention provides a timepiece with automatic winding comprising a power reserve indicator device whose power reserve display mechanism is carried by the oscillating weight.
  • the simplicity and compactness of the invention make its use particularly advantageous. Excellent reliability is ensured, and operation is guaranteed regardless of the level of winding of the mainspring.
  • the display of the information relating to the power reserve is particularly legible, regardless of the position of the oscillating mass.
  • the invention relates to the field of self-winding watches with oscillating weight.
  • the invention proposes to provide a solution to the problem of producing a mechanism for displaying the power reserve integrated with the oscillating weight, which is reliable, simple to implement, and robust.
  • An oscillating mass 1 oscillates in a pivoting movement about a pivot axis D1, generally but not necessarily located at the center of the movement of the watch in which the oscillating weight is installed.
  • This watch conventionally comprises a barrel spring to which are transmitted the movements of the oscillating mass 1 for its reassembly.
  • the invention applies equally to an oscillating weight 1 located below or above the movement of the watch, the latter not being shown in the figures for the sake of simplification.
  • the invention relates to a power reserve indicator device 100 arranged to be integrated in an oscillating weight 1 for self-winding movement.
  • This device 100 comprises display means 20 of the power reserve by comparison with complementary display means 30, for example respectively a needle 2 and a dial 3. These display means 20 and complementary display means 30 are integrated in the oscillating mass 1.
  • both the display means 20 and the complementary display means 30 are rotatably mounted relative to the oscillating mass 1.
  • This rotation is synchronous at a given instant, that is to say that the display means 20 occupy a particular instantaneous angular position relative to the complementary display means 30 as a function of the remaining potential of the mainspring at the instant in question, but this relative angular position of the one with respect to the other is not dependent on the movements printed by the user to the oscillating weight, because, according to the invention, the angular shift of the power reserve display near, the display means 20 and the means of complementary displays 30 are in synchronous rotation with respect to the oscillating mass 1.
  • the display means 20 and the complementary display means 30 are rotatably mounted relative to a common axis of rotation D2.
  • the present invention is illustrated with display means 20 of the power reserve indication constituted by a needle 2, which cooperate with complementary display means 30 constituted by a dial 3. It goes without saying that this example is given purely for illustrative and not limiting, and that the invention can be applied in a similar manner to an indication of the power reserve by means of the cooperation of several dials, or more needles, or other.
  • the differential display mechanism comprises a ball bearing 13, whose inner race carries the oscillating weight 1 by means of a screw 14, and whose outer cage, on the one hand carries a fixed wheel 8 constituting this fixed input, and secondly serves as support in rotation to a movable wheel 4 constituting this movable input.
  • the complementary display means 30 comprise a stop 16.
  • the display means 20 are arranged to cooperate in abutment on this stop 16 in a so-called end of weaving position.
  • This so-called end of winding position corresponds to the end of winding of the mainspring, to which the movable inlet is connected via a gear train.
  • the fixed input cooperates with a disengageable coupling, which is engaged with the complementary display means 30 when the display means 20 are not in abutment on the stop 16, and which is disengaged from the complementary display means 30 when the display means 20 bear on this stop 16.
  • the dial 3 comprises such a stop 16, which is integral with this dial 3.
  • this disengageable coupling comprises a friction wheel 10.
  • This is secured to the complementary display means 30 under the action of elastic return means when the display means 20 are not supported on the stop 16, and is disengaged from the complementary display means 30 when the display means 20 are supported on the latter.
  • the fixed input in particular the fixed wheel 8, cooperates with the wheel friction 10, which is arranged to be secured to the dial 3, under the action of a foil 11 constituting these elastic return means, when the needle 2 is not in abutment on the stop 16, and to be disengaged of the dial 3, when the needle 2 is in abutment on the stop 16.
  • the foil 11 allows the training friction wheel 10 in normal operation, that is during arming or disarming, and disengagement at the end of arming. It is understood that the friction allows the disengagement of the system, which avoids any damage thereof.
  • the dial 3 and the needle 2 turn in the opposite direction of the oscillating weight 1.
  • the ratio is 1 between the different wheels, therefore, the dial 3 and the needle 2 turn in the opposite direction of the oscillating weight 1 but at the same speed, in synchronous rotation at a given moment, giving the user the impression that the dial 3 and the needle 2 do not turn when the oscillating weight 1 rotates.
  • the needle 2 has a relative mobility with respect to the dial 3, depending on the potential of the mainspring: during normal operation, during the winding or disarming of the mainspring, the resultant arrives on the wheel mobile 4 which constitutes the movable input, and allows an angular offset of the needle 2 relative to the dial 3, thus visualizing the power reserve potential.
  • the needle 2 bears on the abutment 16 of the dial 3, which forces the latter to rub on the friction wheel 10, and to shift at the same speed than the needle 2.
  • the moving wheel 4 drives, by means of an intermediate idler wheel 5, an indicator wheel 6 which is secured, preferably via an indicator pin 15, to the display means 20, in particular to the needle 2
  • the fixed wheel 8 drives, via an intermediate return wheel 9, the friction wheel 10, which is mounted free to rotate on an axis 12 secured to the complementary display means 30, in particular the dial 3.
  • the friction wheel 10 and the indicator wheel 6 have the same number of teeth as the moving wheel 4 and the fixed wheel 8, and the intermediate wheels 5 and 9 which make the connection between the display and the center of the movement, are identical to each other.
  • a plate 18 fixed to the oscillating mass 1 comprises bearings for the return wheels 5 and 9, as well as the indicator shaft 5.
  • the invention also relates to an oscillating weight 1 for a self-winding watch, comprising such a power reserve indicator device 100.
  • the invention also relates to a self-winding watch comprising an oscillating weight 1 whose movements are transmitted to a mainspring of this watch, this oscillating mass 1 comprising such a power reserve indicator device 100.
