Definitions

  • the present invention relates to a chronograph comprising a device for driving a second counter by a first counter, the second counter being arranged to count the laps made by the first counter from a zero position of the first counter, the device drive comprising a control finger mounted on the first counter and capable of meshing with a transmission wheel associated with the second counter to drive the latter.
  • the counter called above the first counter is a second counter and the second counter is a minute counter, for example as provided by the patent. CH 571 741 .
  • a similar drive device can be used with different counters, for example to drive an hour counter from a minute counter.
  • the present invention improves the drive device of the second counter by the first so as to allow it to operate in two opposite directions, namely a direct sense where the chronograph adds time in a conventional manner, and a reverse direction where the chronograph performs a countdown, in particular of a duration that the user preselected by putting at least one of the counters in a starting position which defines this duration.
  • the subject of the present invention is a chronograph with two directions of rotation, in which the drive device mentioned above is designed so as to actuate the second counter at a precise instant at the end of a revolution of the first counter, as well as in one sense than in the other.
  • An additional object is to allow precise angular indexing of the control finger relative to the other elements of the device, in order to precisely adjust the moment when it will attack the toothing of the transmission wheel.
  • Another additional object is to arrange the transmission device so as to avoid interference between the control finger and the transmission wheel during the preselection of the duration of the countdown.
  • a chronograph of the kind indicated in the preamble above characterized in that the first and the second counter are capable of rotating in both directions, respectively in an addition mode and a control mode. countdown, the second counter being driven forwards or backwards in the direction of rotation of the first counter, in that the control finger is pivotally mounted on a disk connected to a rotary shaft of the first counter and in that the disk and the control finger are coupled to each other by driving means allowing the control finger to pivot on the disk between two stop positions spaced at an angle close to 360 °.
  • the driving means which define these two stop positions can advantageously be arranged to allow accurate indexing of these positions.
  • the disk is fixed to the shaft of the first counter in an indexed angular position relative to a zeroing yard, by means of which said zero position is defined, and the disk is provided with a spring arranged to maintain the control finger disengaged from the transmission wheel when the first counter is in the zero position.
  • coaching means above mentioned are preferably adjustable to index said abutment positions relative to the zeroing heart.
  • the figure 1 is a front view of a timepiece formed by a wristwatch 10 provided with a mechanical clockwork comprising a timepiece and a chronograph.
  • This watch includes time-keeping hands, namely a 30-hour hand, a minute hand 31 and a small second hand 32.
  • a calendar with a large counter 33 completes the timepiece.
  • the chronograph comprises a seconds counter provided with a needle 34 and a minute counter 11.
  • the starting and stopping of the chronograph, for measuring a time in a conventional manner, are carried out by means of a first pusher 35.
  • a second pusher 36 allows the reset of the minutes and seconds counters.
  • a ring 37 fixed to a control rod allows, according to the axial positions to which it is brought, to reassemble the watch, to update the calendar and to set the time of the timekeeper hands.
  • the chronograph is also used as a timer or countdown timer, the preselection of the duration to be counted being performed by the user by means of the ring 37 so as to turn the minute counter 11 until that it indicates the desired duration, expressed by a whole number of minutes.
  • the start of the countdown and the winding of a spring-loaded barrel operating a bell indicating the end of the countdown are performed by pressing a third push-button 38.
  • the minute counter 11 has a dial 13 located behind a window and having three concentric scales of ten minutes each, which extend each on 120 °.
  • the shaft of the minute counter 11 carries three needles of different lengths, arranged at 120 ° from each other and associated respectively with the three scales. Only one of these needles, designated by the reference 20, is visible in the figure 1 where it currently indicates 14 minutes.
  • the watch 10 further comprises a striking mechanism driven by an auxiliary barrel and controlled by the chronograph, the buzzer being actuated at the end of a preselected time interval which is counted by the chronograph, which is then driven in the opposite direction in the usual sense.
  • the auxiliary barrel thus provides the mechanical energy necessary to actuate the hammers of the striking mechanism, which will not be described here in more detail, while the main barrel provides the mechanical energy necessary for driving the movement. watchmaking and chronograph.
  • the figure 2 shows mechanical control means MC actuated by the pusher 38 and arranged to simultaneously start the countdown and arm the auxiliary barrel 39.
  • the control means MC comprise a control lever 40 pivoted at A on the platen of the movement (not shown), for engaging the countdown, and a winding bar 42 which extends through the movement between the pusher 38 and the auxiliary barrel 39 to arm the latter.
  • the pusher 38 when pressed, performs a stroke L and acts simultaneously on the rocker 40 and on the winding bar 42 via a lever 43 articulated B, provided with pins 44, 45 and 46 and associated with a return spring 47.
  • the arming bar 42 has at its distal end a rack 42a which meshes with a pinion 48 connected to the shaft of the auxiliary barrel 39, while its proximal end cooperates with the pin 45 of the articulated lever 43.
  • the winding bar is guided in translation on nipples 52 integral with the plate of the movement.
  • a displacement in translation of the arming bar 42 under the action of the pusher 38 via the lever 43 drives the pinion 48, which forces the spring of the auxiliary barrel 39.
  • the auxiliary barrel rotates to cause the ringing, it brings back the bar 42 to its initial position with the help of a return spring 55 which acts on a pin 49 of the bar.
  • Flip-flop 40 comprises a body from which four arms 57, 58, 59 and 60 extend.
  • Flip-flop 40 is articulated in a conventional manner at the end of its first arm 57 on the movement stage.
  • the free end of the second arm 58 extends opposite the pin 44 of the lever 43.
  • the third arm 59 cooperates with a column wheel 61 controlled by a device (not shown) connected to the pushers 35 and 37 ( figure 1 ).
  • the fourth arm 60 cooperates with its free end with a jumper spring 62 which indexes two predefined positions of the flip-flop 40.
  • the free end of the fourth arm comprises two notches 63 and 64 in which the end of the jumper 62 is engaged.
  • the tension of the jumper 62 and its position relative to the notches 63 and 64 are adjustable by means of a screw 65 and an eccentric 66 cooperating respectively with two oblong holes formed in one end of the spring 62.
  • the free ends of the arms 58 and 60 each comprise an oblong hole engaged on a corresponding pin 75, 76 to ensure accurate guidance of the latch 40 and a retention thereof against the plate.
  • the arm 60 also carries an inverting wheel 69 in permanent engagement with a chronograph wheel 70 which is carried by a chronograph rocker 77 pivoted at C.
  • the wheel 70 meshes permanently with a wheel 71 whose axis carries the small second needle 32, this wheel 71 being driven by the watch movement.
  • the inverting wheel is engaged on or disengaged from a wheel 72 of the seconds counter, which drives the seconds hand 34 of the chronograph.
  • the column wheel 61 is arranged, on the one hand, to block the latch 40 in a position in which the inverting wheel 69 is disengaged from the wheel 72 when the chronograph addition counting function is engaged, and secondly to lock the chronograph rocker 77 in a position in which the wheel 70 is disengaged from the wheel 72 when the countdown function of the chronograph is engaged.
  • the latch 40 cooperates with an eccentric stop 78 which makes it possible to adjust the penetration depth of the teeth of the inversion wheel 69 in the toothing of the wheel 72 of the chronograph seconds counter.
  • the wheel 81 of the minute counter 11 is a 30-toothed wheel provided with a zero-setting core 81a and associated with a jumper 82 fixed to the plate by a support 83.
  • This wheel meshes on an intermediate transmission wheel 84 which is driven by a control finger 85 of the seconds counter 80.
  • the transmission wheel 84 is carried by a rocker 86 mounted on a pivot 87, to be selectively disengaged from the wheel 81 and the trajectory of the finger 85 by a movement of the rocker. This movement is produced by pressing the Z arrow when resetting the chronograph.
  • the wheel 72 of the seconds counter 80 is attached to a shaft 88 bearing the seconds hand 34 of the chronograph.
  • a zeroing core 90 is fixed on the wheel 72 to define its zero position in a conventional manner, thanks to a hammer 79.
  • the other side of the wheel 72 a disc 91 having a central hub 92 is fitted on a cylindrical seat 93 of the shaft 88, so that it can be rotated by force to index its angular position relative to that of the heart 90.
  • This indexing is operated by means of a key engaging in two holes 91a of the disc 91.
  • a ring 94 provided with the control finger 85 is mounted freely pivotally around the hub 92 of the disc 91.
  • the disc 91 is provided with driving means, formed in this example by two pins 95 and 96, and a holding spring 97 for holding the finger 85 out of engagement with the wheel 84 when the seconds counter is in the zero position.
  • This spring shown separately in Figures 9 and 10 , is formed by a curved steel wire arcuate, guided by a peripheral groove 98 of the disc 91 and having a first end 99 fixed in this groove, for example by gluing.
  • the other end of the spring 97 is bent at right angles, as shown by the Figures 9 and 10 to form an axial shaft 100 with respect to the disk.
  • the spring forms a nose 101 intended to engage in the groove 98.
  • the spring 97 is slightly supported at the bottom of the groove 98.
  • the two pins 95 and 96 are substantially parallel to the shaft 88 and are located substantially on the same radial line of the disc 91, but at different distances from the axis 103 of the disc and the shaft. These pins are driven into respective holes of the disc, from which they are prominent next to the ring 94. They are preferably made of brass, so that they can deform by folding.
  • the peg 95 is intended to abut against a first flank 104 (see figure 7 ) of the finger 85, and the other pin 96 is intended to abut against the opposite flank 105 of the finger 85.

  • the pins 95 and 96 thus define the stop positions of the control finger 85, positions in which this finger is respectively on one side or the other of the drive means formed by the two pins. These positions are indexed with respect to the heart 90 of the seconds counter, firstly by the positioning of the plate 91, then in a fine manner by lateral folding of each pin 95 and 96 if necessary.
  • the active stroke of the finger 85 in the reverse direction to decrement the minute counter is effected after the same rotation angle of the seconds counter, starting from the zero position, that the active stroke of the finger in the forward direction to increment the minute counter.
  • the two pins 95 and 96 could be replaced by a single drive element.
  • the use of two dowels is advantageous in two ways. On the one hand, it allows a very precise indexing of the two abutment positions of the control finger, by folding the pins as explained above.
  • the pins 95 and 96 could be attached to the ring 94 and engaged in respective grooves of the disc 91.
  • the embodiment shown in the drawings is more advantageous because it allows easy access to the ankles 95 and 96 through openings of the wheel 72 to adjust them by folding.
  • the disc 91 could be integrated either to the wheel 72 or the core 90.
  • the peripheral spring 97 should then be replaced by a spring disposed in a cavity of the disc.
  • the chronograph mechanism represented in the Figures 3 and 4 operates in the following manner, the seconds counter 80 being initially at its zero position shown in FIG. figure 3 .
  • the seconds counter 80 is driven in the direction of the arrow R by the inverting wheel 69 shown in FIG. figure 2 .
  • the control finger 85 is then no longer supported by the spring 97 and can pivot under the effect of friction to rest against a tooth of the transmission wheel 84.
  • the pin 95 Shortly before the end of a complete revolution of the 80 seconds counter, the pin 95 will abut against the corresponding side of the finger 85 and force it to set back a tooth wheels 84 and 81 overcoming the force of the jumper 82, so that the minute counter 11 is decremented by one minute every sixtieth second of the countdown.
  • the reset of the chronograph is controlled by pressing on the pusher 36, which firstly pivots the lever 86 to disengage the transmission wheel 84 of the two counters 11 and 80, and then conventionally press the hammer 79 on the cores 81 a and 90 of the two counters and bring them back to their zero position.
  • the control finger 85 can occupy any position.
