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 for drive comprising a control finger mounted on the first counter and capable of engaging on 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 for in 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 device for driving the second counter by the first so as to allow it to operate in two opposite directions, namely a direct direction where the chronograph adds time in a conventional manner, and an opposite direction where the chronograph performs a countdown, in particular of a duration that the user has preselected by putting at least one of the counters in a starting position which defines this duration.
- the present invention relates to a chronograph with two directions of rotation, in which the above-mentioned driving device is produced so as to activate the second counter at a precise instant at the end of a revolution of the first counter, as well one way than the other.
- An additional aim is to allow precise angular indexing of the control finger relative to the other elements of the device, in order to precisely regulate the moment when it will attack the toothing of the transmission wheel.
- Another additional object consists in arranging the transmission device so as to avoid interference between the control finger and the transmission wheel during the preselection of the countdown duration. We seek to fulfill these goals by means of a simple and space-saving construction.
- 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 in a mode of countdown, the second counter being driven forwards or backwards according to the direction of rotation of the first counter, in that the control finger is pivotally mounted on a disc linked to a rotary shaft of the first counter and in that the disc and the control finger are coupled to each other by driving means allowing the control finger to pivot on the disc between two stop positions spaced at an angle close to 360 °. This allows the control finger to occupy one or the other of the two stop positions, depending on the direction of rotation, at the moment when it must start to drive the transmission wheel at the end of a complete revolution.
- the driving means which define these two stop positions can advantageously be arranged to allow precise indexing of these positions.
- the disc is fixed on the shaft of the first counter in an angular position indexed relative to a zero-setting core, by means of which said zero position is defined, and the disc is provided with a spring arranged to maintain the control finger released from the transmission wheel when the first counter is in the zero position.
- the above-mentioned driving means are preferably adjustable for indexing said abutment positions relative to the zeroing core.
- FIG. 1 represents a wristwatch comprising a timepiece and a chronograph with two directions of rotation according to the invention
- FIG. 2 represents the mechanism intended to start the countdown
- FIG. 3 represents elements of the seconds and minutes counters of the chronograph, seen from the side opposite to the watch face
- FIG. 4 is a side view of the seconds counter
- FIG. 5 is a plan view of a disk of the second counter
- FIG. 6 is a sectional view along line VI-VI of FIG. 5,
- FIG. 7 is a plan view of another element of the second counter
- FIG. 8 is a side view in partial section of the element of Figure 7
- - Figure 9 is a plan view of a spring of the seconds counter
- FIG. 10 is a side view of the spring of Figure 10.
- FIG. 1 is a front view of a timepiece formed by a wristwatch 10 provided with a mechanical clockwork movement comprising a timepiece and a chronograph.
- This watch has timepiece hands, namely an hour hand 30, a minute hand 31 and a small second hand 32.
- a calendar with large aperture 33 completes the timepiece.
- the chronograph comprises a seconds counter provided with a hand 34 and a minutes counter 11. The chronograph is started and then stopped, in order to measure a time in a conventional manner, by means of a first push-piece 35.
- a second push-button 36 allows the minutes and seconds counters to be reset to zero.
- a crown 37 fixed to a control rod makes it possible, according to the axial positions to which it is brought, to wind the watch, to bring the calendar up to date and to set the time hands of the timepiece.
- the chronograph is also used as a timer or countdown timer, the preselection of the time to be counted down being carried out by the user by means of the crown 37 so as to rotate the minute counter 11 until that it indicates the desired duration, expressed by an integer number of minutes.
- the start of the countdown and the reassembly of a spring barrel activating a ring signaling the end of the countdown are carried out by pressing a third button 38.
- the minute counter 11 has a dial 13 located behind a window and comprising 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 one another and associated respectively with the three scales. Only one of these hands, designated by the reference 20, is visible in Figure 1 where it currently indicates 14 minutes.
- Watch 10 further comprises a striking mechanism driven by an auxiliary barrel and controlled by the chronograph, the striking being actuated at the end of a preselected time interval which is counted down by the chronograph, which is then driven in the opposite direction. in the usual sense.
- the auxiliary barrel therefore provides the mechanical energy necessary for actuating 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 of horology and chronograph.
- FIG. 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 rocker 40 pivoted in A on the movement plate (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 by means of a lever 43 articulated at B, provided with pins 44, 45 and 46 and associated with a return spring 47.
- the winding 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 pins 52 secured to the movement plate.
- a displacement in translation of the winding bar 42 under the action of the pusher 38 via the lever 43 drives the pinion 48, which arms the spring of the auxiliary barrel 39.
- the auxiliary barrel rotates to cause 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.
- the rocker 40 comprises a body from which extend four arms 57, 58, 59 and 60.
- the rocker 40 is articulated in a conventional manner at the end of its first arm 57 on the plate of the movement.
- 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 by its free end with a jumper spring 62 which makes it possible to index two predefined positions of the lever 40.
- the free end of the fourth arm comprises two notches 63 and 64 in which the end of the jumper 62 engages.
- 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 stud 75, 76 in order to ensure precise guidance of the lever 40 as well as a maintenance of the latter against the plate.
- the arm 60 further carries an inverting wheel 69 in permanent engagement with a chronograph wheel 70 which is carried by a chronograph rocker 77 pivoted in O.
- the wheel 70 permanently meshes with a wheel 71 whose axis carries the small second hand 32, this wheel 71 being driven by the clockwork movement.
- the reversing wheel is engaged on or released 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 lock the rocker 40 in a position in which the inverting wheel 69 is released from the wheel 72 when the counting function by addition of the chronograph is engaged, and on the other hand to lock the chronograph lever 77 in a position in which the wheel 70 is released from the wheel 72 when the countdown function of the chronograph is engaged.
- the lever 40 cooperates with an eccentric stop 78 which makes it possible to adjust the depth of penetration of the teeth of the reversing wheel 69 into the teeth of the wheel 72 of the chronograph seconds counter.
- the wheel 81 of the minute counter 11 is a wheel with 30 teeth, provided with a zero-setting core 81a and associated with a jumper 82 fixed to the plate by a support 83.
- This wheel meshes with 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 from the path of the finger 85 by a movement of the rocker. This movement is produced by pressing the arrow Z when the chronograph is reset.
- the wheel 72 of the second counter 80 is fixed to a shaft 88 carrying the second hand 34 of the chronograph.
- a zero-setting core 90 is fixed to the wheel 72 to define its zero position in a conventional manner, using a hammer 79.
- a disc 91 having a central hub 92 is adjusted to a cylindrical bearing surface 93 of the shaft 88, so that it can be made to rotate by force to index its angular position relative to that of the heart 90. This indexing is effected by means of a key engaging two holes 91a of the disc 91.
- a ring 94 provided with the control finger
- the disc 91 is provided with driving means, formed in this example by two pins 95 and 96, and a spring of holding 97 intended to hold the finger 85 out of grip of the wheel 84 when the seconds counter is in the zero position.
- This spring shown separately in FIGS. 9 and 10, is formed by a steel wire curved in an arc of a circle, guided by a peripheral groove 98 of the disc 91 and having a first end 99 fixed in this groove, for example by bonding. .
- the other end of the spring 97 is bent at right angles, as shown in Figures 9 and 10, to form an axial rod 100 relative to the disc. At the base of this rod, the spring forms a nose 101 intended to engage in the groove 98. At rest, the spring 97 bears lightly 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 in the disc, from which they are prominent next to the ring 94. They are preferably made of brass, so that they can be deformed by folding.
- the pin 95 is intended to abut against a first flank 104 (see FIG. 7) of the finger 85, and the other ankle 96 is intended to abut against the opposite flank 105 of the finger 85.
- the finger 85 has a recess lateral 106 intended to receive the rod 100 of the spring 97.
- the pins 95 and 96 thus define stop positions of the control finger 85, positions in which this finger is located respectively on one side or the other of the drive means formed by the two pins. These positions are indexed relative to the heart 90 of the second counter, first by positioning the plate 91, then in a fine manner by lateral folding of each pin 95 and 96 if necessary.
- Two very precise positions P1 and P2 are thus defined (see FIG. 5) of the finger 85, angularly spaced by an angle A slightly less than 360 °, this angle being determined by the relative positions of the pins 95 and 96 on the one hand, and flanks 104 and 105 of the finger on the other hand.
- the active stroke of the finger 85 in the rearward direction to decrement the minute counter takes place after the same angle of rotation of the second counter, from the zero position, as 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 pegs is advantageous for two reasons. On the one hand, it allows very precise indexing of the two stop positions of the control finger, by folding the ankles as explained above. On the other hand, it makes it possible to reduce the angle B to a very small value, or even zero, if the base part 107 of the finger 85 is given a sinuous shape such as its sides 104 and 105, which are offset radially with respect to each other, can be brought closer in circumferential direction than in Figure 7. If the base 107 had a Z shape, the flank 105 could even be higher than the flank 104 in the figure 7, so that the two finger stop positions could be identical, that is to say offset by 360 ° exactly.
- the pins 95 and 96 could be fixed to the ring 94 and engaged in respective grooves of the disc 91.
- the execution shown in the drawings is more advantageous because it allows easy access to the pins 95 and 96 through the openings of the wheel 72 to adjust them by folding.
- the disc 91 could be integrated either with the wheel 72 or with the heart 90.
- the peripheral spring 97 should then be replaced by a spring placed in a cavity of the disc.
- the chronograph mechanism shown in FIGS. 3 and 4 operates in the following manner, the second counter 80 being initially at its zero position shown in FIG. 3.
- the wheels 84 and 81 at the end of a full revolution of the second counter 80, that is to say during the sixtieth second, which increments the minute counter by one minute 11. This operation is repeated at each revolution of the second counter 80.
- the second counter 80 is driven in the direction of the arrow R by the reversing wheel 69 shown in FIG. 2.
- the control finger 85 is then more supported by the spring 97 and can pivot under the effect of friction until it leans against a tooth of the transmission wheel 84.
- the pin 95 Shortly before the end of a full revolution of the seconds counter 80, the pin 95 goes abut against the corresponding flank of the finger 85 and force it to move the wheels 84 and 81 backward by one tooth overcoming the force of the jumper 82, so that the minute counter 11 is decremented by one minute for each sixtieth second of the countdown.
- the resetting of the chronograph is controlled by pressing the pusher 36, which first of all pivots the lever 86 to disengage the transmission wheel 84 from the two counters 11 and 80, then conventionally press the hammer 79 on the cores 81a and 90 of the two counters and return these to their zero position. During this operation, the control finger 85 can occupy any position.
