Definitions

  • the present invention relates to a timepiece comprising a winding stem and time setting axially movable between at least one winding position and a time setting position and a manual control member of a rack of a recurring striking mechanism.
  • any triggering of the buzzer during the time setting is likely to cause great damage because the cams or snails of the striking mechanism are integral with the roadway carrying the needle. minutes. Therefore, any displacement of the roadway causes that of the cams or sniffs of the ring while the probes of the striking mechanism are engaged with these cams or snails to take the information relating to the hours, quarters and minutes to ring .. It results from this displacement of the roadway while these probes are engaged with the ringing cams of the important damages of the feelers and the cams.
  • EP 1 760 551 A mechanism that can fulfill both functions has been described in EP 1 760 551 .
  • This mechanism relates to a timepiece of great ringing and repetition and not to a repetition mechanism in which the ringing is triggered only at the request by a lever which causes, by the movement of a rack, the arming a spring triggering at the same time the striking mechanism.
  • a cam connected kinematically to the winding stem serves to prevent the movement of the triggering member of the ring.
  • the striking mechanism is driven by the constantly armed ringing spring to ring the hour passing as well as on demand (repetition) and not by a spring manually cocked by the rack arm that will push the toothed sector rack of the repetition mechanism.
  • the triggering of the repetition of the great ring is therefore only to act on the trigger mechanism, without acting on a rack.
  • the object of the present invention is to allow the blocking of a repetition during the time setting.
  • this invention relates to a timepiece of the aforementioned type comprising a mechanism for locking the rack and a kinematic connection between the winding stem and the locking mechanism, to activate this locking mechanism, when the rod winder is in the time setting position.
  • the figure 1 is a partial plan view on the dial side of this timepiece, showing the locking mechanism of the repetition in the deactivated position;
  • the figure 2 is the same view as the figure 1 , representing the locking mechanism in the activated position.
  • FIGS. 1 and 2 illustrate a timepiece with a rehearsal mechanism.
  • this mechanism is of a very classical design, only the elements necessary for the understanding of the invention have been represented.
  • a winding mechanism and time setting essentially comprising a sliding pinion 1 slidably mounted on a winding and setting rod W, a rocker 2 in mesh with a groove of the sliding pinion 1 and whose displacement is controlled by a pull rod 3 which usually comprises a stud (not visible) engaged in a groove of the winding stem W, so that the angular position of the pull rod around its pivot axis (not shown) is a function of the axial position of the winding stem W and moves the rocker 2 when it is moved outward in the time setting position.
  • This pull rod 3 further comprises a stud 3a engaged in a notch provided at one end of a rocker 4 pivotally mounted around a fixing screw with a bearing surface 5.
  • This rocker constitutes the kinematic transmission of the axial position of the winding stem W
  • the other end of the latch 4 is engaged with a locking lever 6 pivotally mounted about a support surface in an arc. 6a.
  • a return spring 7 tends to hold the locking lever 6 against a stop 9.
  • This locking lever 6 has a semicircular notch 6b at its end opposite to that engaged with the latch 4. This notch 6b is intended to engage with a locking pin 8a of the rack 8 of the mechanism of repetition, pivotally mounted about an axis 8b.
  • This rack 8 is integral with an arm 8c for rotating the rack 8 in the direction of clockwise to arm the spring of the repetition (not shown) and trigger the repetition mechanism.
