Definitions

  • the present invention relates to a time-setting mechanism for a watch movement of a watch comprising a device for blocking the cog of the time-setting in order to avoid movement of the hands in the event of impacts.
  • a friction system is generally provided for this purpose in order to guarantee an easy adjustment of the time while ensuring a reliable driving of the hands by the gear train during the running of the watch.
  • a well-known friction system is lanterning, which consists of adjusting the carriageway on the center pinion rod in order to obtain a "greasy friction" to allow setting the time without causing the train of finishing.
  • the thickness of the roadway is reduced in the middle and is pinched by means of a tool dedicated for this purpose so as to form a projection which presses against a conical notch of the rod of the center pinion.
  • the document CH 704 331 discloses a time-setting mechanism for a watch movement according to the preamble of claim 1.
  • the document WO 2007/115984 discloses a timepiece with a mechanism with two time zones to indicate a reference time and a corresponding local time.
  • the offset between the local time and the reference time is adjustable.
  • the documents CH 237 215 , JP S49 62457 , JP H02 683 and GB 2,071,364 disclose locking devices of a train different from the time setting train.
  • the aim of the present invention is to provide a time-setting mechanism in order in particular to overcome the drawbacks of the aforementioned state of the art and to avoid any drift in the display of the time during impacts important to the watch.
  • the time-setting mechanism according to the invention further comprises a device for blocking the time-setting train.
  • This locking device comprises a first and second locking arm and a wheel blocking in engagement with the time-setting train.
  • the first and second locking arms are arranged, on the one hand, to be engaged with the locking wheel in a so-called locked configuration in which the time-setting train is locked and, on the other hand, to be released from the locking wheel in a so-called unlocked configuration in which the sliding pinion is free to mesh with the time train.
  • the locking device comprises for this purpose a locking / unlocking lever engaged with the sliding pinion and arranged to cooperate with the first and second locking arms in order to effect a transition from the locked configuration to the unlocked configuration and vice versa when the winding stem is brought from a running position to a time setting position and vice versa.
  • the locking wheel has a toothing whose apex of each tooth has a curved profile.
  • the first and second locking arms each have a portion having a curved edge provided with microtoothing.
  • the radius of curvature of the curved edge of the first and second locking arms corresponds essentially to the radius of the head circle of the locking wheel.
  • These micro teeth are intended to come into contact with the teeth of the locking wheel in the locked configuration of the locking device.
  • the particular profile of the toothing of the locking wheel and of the micro toothing has the advantage of allowing angular precision of locking of the wheel so that the deviation of the hands is negligible after correction of the time when the stem of winder is returned to the on position.
  • the micro teeth of the first and second locking arms are symmetrical with respect to each other so as to prevent any rotation of the locking wheel in both directions.
  • first and second locking arms are superposed and mounted to pivot relative to each other about a common axis.
  • the curved edge of the lower, respectively upper locking arm is intended to come into contact with a lower, respectively upper portion of the toothing of the locking wheel.
  • one or both arms of blocking may include an additional thickness in the part comprising the microtoothings arranged so as to provide support for the two arms of the same height on the blocking wheel.
  • the locking / unlocking lever is arranged to pivot around a pivot when the winding stem is brought from a running position to a time setting position and vice versa.
  • This locking / unlocking rocker comprises two arms extending on either side of the pivot. One end of one of the two arms is in engagement with the sliding pinion whereas the other of the two arms has a distal portion intended to cooperate with the upper locking arm and a proximal portion intended to cooperate with the lower locking arm.
  • the distal portion is in abutment against a rectilinear flank of the upper locking arm.
  • the proximal portion for its part, is in abutment or is intended to abut against an actuating element, preferably a pin, of the lower locking arm in order to release the locking arms from the toothing of the locking wheel when the locking / unlocking rocker pivots under the effect of the axial displacement of the sliding pinion.
  • the locking wheel is the timer wheel of the time-setting train.
  • the locking wheel is mounted integral with the axis of a standard timer wheel of the time-setting train.
  • the time-setting mechanism comprises, conventionally, a pull tab 12 comprising a lug 12a housed in a recess in the winding stem 10, a rocker 14 arranged to cooperate with the pull tab 12, and a sliding pinion 16.
  • a pull tab 12 comprising a lug 12a housed in a recess in the winding stem 10
  • a rocker 14 arranged to cooperate with the pull tab 12, and a sliding pinion 16.
  • This is adjusted on a segment 17a of square cross section of a secondary rod 17 so as to be able to move along this segment 17a from a first axial position, in which the sliding pinion 16 is engaged with a pinion winder 18, in a second axial position, in which the sliding pinion 16 is engaged with a reference 19 of the time-setting train as illustrated in the figure 2b .
  • the lever 14 has an end 14a arranged in a circular groove 16a of the sliding pinion 16.
  • the pull tab 12 pivots and pushes back the rocker 14 which slides the sliding pinion 16 along the segment 17a of the secondary rod 17.
  • the sliding pinion 16 thus emerges from the winding pinion 18 to come to mesh with the gear 19 of the time-setting train for the needle control.
  • the time-setting mechanism further comprises a device for blocking the time-setting train.
  • This device includes a locking wheel 20 configured to cooperate on the one hand with the time-setting train and on the other hand with a first and second locking arm 22, 30.
  • the locking wheel 20 has a toothing whose apex of each tooth has a curved profile. This particular profile of the toothing of the locking wheel 20 makes it possible, on the one hand, to retain a toothing allowing engagement with the sliding pinion 16 via the references for setting the time, in order to fulfill the function of a standard timer wheel, and on the other hand, to increase the angular precision of the blocking by the first and second blocking arm 22, 30.
  • the latter each comprise a portion 28, 32 having a curved edge extending along an arc of a circle of an angle preferably between 30 ° and 40 °, the radius of curvature of which corresponds essentially to the radius of the head circle of the locking wheel 20.
  • the curved edges of the locking arms 22, 30 are provided with microtoothing in order to increase the points of contact with the teeth of the locking wheel 20 when the curved edges are in contact with the latter . This has the advantage of increasing the angular precision of the blocking.
  • the first and second locking arms 22, 30 are moreover superimposed and mounted pivoting with respect to one another around a tenon 36.
  • the microtoothings of the upper locking arm 22 and of the lower locking arm 30 are held against an upper, respectively lower portion of the teeth of the locking wheel 20 by a spring (220 and 300), when the locking device is in a locked configuration.
  • These two micro teeth have a symmetry with respect to an axis passing through the center of the locking wheel 20 and by the pivot axis of the two blocking arms 22, 30. The two micro teeth are therefore oriented in an opposite direction.
  • the pavement has the advantage of being able to be simply adjusted on the barrel of the minute wheel without any "greasy friction", which makes it possible to overcome the problems wear of the time setting gear or the risk of damaging the finishing gear when the "greasy friction" is not optimal.
  • the first locking arm 22 comprises a spout 26 provided with a rectilinear flank 24 extending from the tip of the spout 26 to a corner 25 forming an obtuse angle.
  • the second locking arm 30 comprises, for its part, a pin 34 extending vertically relative to the plane in which the second arm is arranged to pivot
  • the device for blocking the time-setting train further comprises a locking / unlocking lever 40 intended to lock and unlock the locking wheel 20.
  • this locking / unlocking lever 40 is arranged to pivot around a tenon 46 and has two arms 42, 44 extending on either side of the tenon 46.
  • One end of one of the two arms 42 is housed in the circular groove 16a of the sliding pinion 16 opposite the end 14a of the rocker 14.
  • the end of the arm 42 of the locking / unlocking rocker 40 and the end 14a of the rocker 14 are arranged on either side of a rod connecting the part of sliding pinion 16 intended to mesh with the gear 19 and the part of the sliding pinion 16 intended to mesh with the winding pinion 18.
  • the other of the two arms 44 of the locking / unlocking lever 40 is similar to a bent arm comprising a distal portion 44a and a proximal portion 44b ( figure 2a ).
  • the distal portion 44a has a pointed end housed in the corner 45 of the first locking arm 22 when the device for blocking the time-setting train is in a locked configuration.
  • the proximal portion 44b is intended to come into abutment against the pin 34 of the second locking arm 30 when the winding stem 10 is brought into a position for setting the time.
  • the device for blocking the time-setting train is in a locked configuration, that is to say that the blocking wheel 20 is locked by the first and second blocking arm 22, 30 thus guaranteeing the blocking of the time-setting mechanism in the event of large shocks to the watch during normal running of the watch.
  • the winding stem 10 When it is necessary to set the time, the winding stem 10 is brought from a first axial position corresponding to a running position of the watch to a second axial position corresponding to a setting position. watch time.
  • the axial displacement of the winding stem 10 actuates the pulling rod 12 in rotation, which will in turn actuate the rocker 14 so that its end 14a moves the sliding pinion 16 along the segment 17a of the secondary stem 17 from a first position axial, in which it is engaged with the winding pinion 18 to a second axial position, in which it is engaged with the reference 19 of the time train.
  • the arms 42, 44 of the locking / unlocking lever 40 pivot around the tenon 46 counterclockwise under the action of the sliding pinion 16 on the end of the arm 42 when it moves from its first position to its second axial position.
  • the pointed end of the distal portion 44a of the arm 44 will exert a stress on the straight flank 24 of the first arm blocking 22, while moving along this sidewall 24 so that the first arm 22 pivots around the lug 36 so as to release the first microtoothing of the locking wheel 20.
  • the proximal portion 44b comes to bear against the pin 34 of the second locking arm 30 in order to release the second micro-toothing from the locking wheel 20.
  • the locking device as illustrated in the figure 2b is in an unlocked configuration and setting the time has the advantage of being able to be done without risk of damaging the gear train since, as mentioned above, the pavement is simply adjusted on the barrel of the minute wheel without any "Greasy friction".
  • the winding stem 10 is returned to the first axial position, and the locking / unlocking lever 40 pivots around its tenon 46 clockwise, which brings the arm 44 back into the position illustrated in figure 2a .
  • the first and second coupling arms 22, 30 pivot around the tenon 36 under the action of their respective return spring in order to bring back and maintain their respective micro teeth against the teeth of the locking wheel 20 thus locking the locking device so that the watch is insensitive to possible large shocks.
  • the locking wheel 20 could fulfill only the function of blocking the time-setting train without fulfilling the function of the timer wheel.
  • the teeth of the locking wheel will then only be dedicated to cooperate with the teeth of the locking arms and the number of teeth may be increased to improve the angular precision of the locking.
  • the sliding pinion is adjusted to move on a segment of a secondary rod offset from the winding rod.
  • this construction is dictated by the constraints of a particular watch movement.
