Definitions

  • the present invention relates to a timepiece with a date mechanism, comprising a date mobile in engagement with an angular positioning jumper, a mobile for driving this mobile dates, a desmodromic link between this drive and a mobile phone.
  • timer train for rotating said drive wheel at a rate of one revolution per twenty-four hours, an instantaneous jump cam, an elastic energy accumulator in engagement with said cam to move it instantaneously once per turn of said mobile drive, a finger kinematically connected with this cam to drive the mobile dates, a kinematic link between the drive wheel and the cam, with a degree of freedom chosen to allow the elastic energy accumulator to release its energy by communicating a relative movement, to allow the drive finger to move the mobile dates instantly 'a step.
  • the mobile indicator of the calendars may be driven more than one step by the instant jump drive mechanism, thus causing the indicator to jump two or even three calendars.
  • the object of the present invention is to overcome, at least in part, the aforementioned drawbacks.
  • this invention relates to a timepiece with a date mechanism of the aforementioned type as defined in claim 1.
  • the main advantages of the solution which is the subject of the invention are the fact that the position of the finger in the normal state is perfectly defined and that the spring which maintains the finger in this normal position is pre-armed. Another advantage is that the instant jump calendar mobile device does not have to overcome the force that keeps the drive finger in its normal position. As a result, the drive finger behaves like a rigid finger, except when the mobile of the dates is moved while this finger is engaged in its toothing. Finally, the number of parts involved is reduced to a minimum and this device does not require any adjustment during assembly.
  • the mechanism illustrated in FIG. 1 comprises a mobile of dates 1 in the form of a ring or a disc bearing the numbers of 0 to 31 (not shown) with internal teeth 1a of thirty-one teeth, in engagement with a jumper 2 positioning spring.
  • a drive wheel 3 (FIG. 2) of the mobile of the dates 1 meshes with a pinion 4a of a reduction gear 4 meshing with the hour wheel 5 or barrel wheel.
  • This hour wheel 5 makes a turn in twelve hours and the gear ratio between this hour wheel 5 and the drive wheel 3 is 2/1 so that the drive wheel 3 makes a turn in twenty-four. hours.
  • the drive wheel 3 is integral with a hub 3a pivotally mounted on an axis 6.
  • This hub 3a carries an instantaneous jump cam 7 in which an eccentric pin 7a is driven ( Figures 2 and 3).
  • This eccentric peg 7a passes through an annular sector-shaped opening 3b, centered on the axis of the drive wheel 3.
  • This eccentric peg 7a also passes through one end of a return spring 8 through which the hub also passes. 3a of the drive wheel 3, so that this end of the return spring 8 is held firmly between these two fastening elements 3a and 7a.
  • the eccentric peg 7a passes through a plate-shaped disengagement member 9, also provided with an elongate opening 9a delimited at its ends by two arcs of circles of the same radius interconnected by two concentric circle arcs of which the radii differ from the value of the diameters of the two arcs delimiting the ends of the opening 9a.
  • the foot of the perpendicular lowered from the axis of the eccentric peg 7a to the line joining the centers of the two arcs of circles delimiting the ends of the elongated opening 9a is located midway between the centers of these two arcs of circles ( Figure 2).
  • the release member 9 can rotate about the axis of the eccentric pin 7a with an amplitude corresponding to the distance separating the centers of the two arcs of circles delimiting the ends of the elongated opening 9a.
  • This release member 9 carries on one side a drive pin 9b intended to engage with the toothing 1a of the date ring 1. On the other side, this release member 9 carries a circular projection 9c at which a curved end 8a of the return spring 8 is hung by subjecting the return spring 8 to a predetermined pre-stress . Thanks to this arrangement, the drive finger 9b behaves like a rigid finger during the drive of the mobile date 1, since the elongate opening 9a of the release member 9 is held in abutment against the hub 3a of the drive wheel 3.
  • the release member 9 is pivotable about the eccentric peg 7a, against the force of the spring 8, in the position shown in FIG. 5, allowing the drive finger 9b to to clear to let the tooth of the teeth 1a of the date mobile 1.
  • the date mechanism also comprises an energy accumulator for the instantaneous jump of the mobile of the dates.
  • This energy accumulator (FIG. 1) comprises a lever 10 provided with a roller 10a applied against the edge of the cam 7 by an instantaneous jump spring 11.
  • FIG. 1 illustrates this instantaneous jump date mechanism just before the jump instantaneous, at the moment when the maximum energy is accumulated in the instantaneous jump spring 11 by the tilting of the lever 10 in the opposite direction to that of the clockwise. This position corresponds to midnight.
  • the cam 7 is driven by the edge of the annular sector-shaped opening 3b of the drive wheel 3 from the position illustrated in FIG.
  • the roller 10a passes the top of the cam 7 which allows to the energy of the instantaneous jump spring 11 to be released by suddenly rotating the cam 7, the release member 9 with its drive finger 9b and the return spring 8, to the position shown in Figure 2 'in which the disarming of the instantaneous jump spring 11 is stopped by a slightly concave portion 7b of the cam 7, making it possible to advance the mobile of the dates 1 by one step in cooperation with the spring-loaded positioning jumper 2.
  • the driving finger 9b behaves like a rigid finger because the elongate opening 9a of the body of the clearance 9 is maintained by the return spring 8 against a stop formed by the hub 3a of the drive wheel 3, the pivot axis is coaxial with that of the drive pin 9b.
  • the trajectory of this drive finger 9b is thus perfectly defined, in this case, the drive finger thus behaves like a fixed finger.
  • the spring 8 is pre-armed, it is possible to define precisely the torque necessary to maintain the opening 9a of the release member 9 abutting against the hub 3a to allow the retention of the date mobile 1 after the instantaneous jump, but allowing the release of the drive finger 9b by pivoting the release member 9 around the eccentric pin 7a, when the dates mobile is manually operated by the date reset device.
