Definitions

  • the present invention relates to a chronograph watch comprising first and second hands controlled by motor means comprising first and second rotors capable of driving at least one needle step by step independently of the other, said hands being capable of displaying , in response to the actuation of a control device controlling an electronic circuit, either the time of day indicating the hour and the minute, or a timed time indicating the minute and the second, device with which a origin of the times can be chosen, the watch can be set to the time and the chronograph started, frozen, stopped and reset to zero, and first and second counters capable of memorizing the time of day and the time respectively stopwatch.
  • a chronograph watch that partially meets the above definition is already known. This includes a dial surmounted by two single hands. Normally, the watch displays the time of day, the hands indicating the hour and the minute. This watch has only one crown stem which, in the pulled position, allows the time to be set by rotating the crown. If the crown is pressed while the hands display the time, the hands will position themselves at noon or at the chronograph zero and immediately start counting the time interval (START). Thus, the hands of the timepiece which indicated the hour and the minute are transformed into chronograph hands which now indicate the minute and the second respectively. Pressing the crown again stops the chronograph (STOP) and allows the timed time to be read.
  • STOP chronograph
  • the cited chronograph watch therefore includes a first counter capable of memorizing the time of day and a second counter capable of memorizing the timed time. It also includes a device making it possible to fix an origin for the hands, this being necessary at the time of the change of battery supplying the watch or after an impact which would have accidentally displaced the hands.
  • This chronograph watch however has several drawbacks which have been overcome in the subject of the present invention.
  • One drawback is that it cannot measure cumulative times, that is to say, from the STOP position, restart a new timing.
  • Another drawback is that it does not offer a GEL function which can be defined by stopping the hands and continuously increasing the chronograph counter so that if the chronograph is restarted, the hands progress rapidly that they indicate the timed time that they would have indicated if the GEL function had not been ordered. This is the well-known split-second function of mechanical chronographs.
  • Yet another disadvantage is that, once the chronograph has been started, it cannot quickly return to the time of day. We have seen that this return is only made after 3 1/2 minutes.
  • the watch of the invention therefore makes it possible to measure a time interval, to view it by the hands on demand while memorizing the information which is then no longer displayed.
  • the time interval can be possibly extended (time accumulated) or canceled (reset). It is possible to return to the display of the hourly information by the hands either automatically after a few minutes of operation, or by pressing a button. From this moment, the counting of the time interval continues and is memorized. This is the GEL function mentioned above. Pressing the same button then makes it possible to catch the memorized time.
  • the chronograph watch of the invention is characterized in that its control device comprises at least first and second pushers excluding any crown-stem, pushers thanks to which in particular, either the time of day or the timed time can be viewed at any time on request.
  • the chronograph watch of the invention is shown in FIG. 1. It includes first (1) and second (2) hands controlled by motor means which will be described below.
  • these hands are capable of displaying, in response to the actuation of a control device comprising here pushers A and B, either the time of day indicating the time and the minute, a timed time indicating the minute and the second.
  • a control device comprising here pushers A and B
  • hands 1 and 2 display 9 hours 15 minutes if the chronograph watch indicates the hour and 46 minutes 15 seconds if it indicates the timed time.
  • the control device A and B makes it possible to choose an origin of time, to set the watch to the time and to set the chronograph on or off, to stop it or bring it back to zero.
  • the chronograph watch in FIG. 1 also includes first and second counters capable of memorizing the time of day and the timed time respectively, as will be clearly seen in FIG. 6.
  • hands 1 and 2 in addition to the functions described in the above paragraph, are also capable of displaying an alarm time.
  • the control device A and B makes it possible, in addition to the preceding choices, to choose an alarm time which will be signaled or not signaled by an audible transducer depending on whether the system is armed or disarmed respectively.
  • the chronograph watch will therefore include, in addition to the first and second counters mentioned above, a memory capable of memorizing the alarm time, as will be clearly seen in FIG. 9.
  • the invention is mainly characterized by the fact that the control device comprises at least a first pusher A and a second pusher B, to the exclusion of any crown-stem, these plungers making it possible in particular to display at any time and on request, either the hour of the day, or the timed time.
  • the motor means driving the needles 1 and 2 comprise first and second rotors capable of driving at least one needle step by step independently of the other.
  • a motor is described in document CH-B-675 940.
  • FIG. 2 of the present description illustrates this motor which has two rotors 3 and 4, a common magnetic circuit 5, a coil core 6 and a coil 7 magnetically coupled with rotors 3 and 4.
  • These drive two coaxial wheels 11 and 12 integral with needles 1 and 2 respectively (not shown).
  • the ASIC circuit includes the block diagrams of Figures 3 and 6, as well as that of Figure 9 if an alarm is expected.
  • step e) the double press of step e) above also results in the resetting of the last stages of the frequency divider 31 shown in FIG. 6 as well as the inhibition of motor control, any new pulse coming from the time base being stopped (STOP function).
  • Buttons A and B are assigned to the operation of the chronograph apart from the operations which have been reviewed above relating to the ORIGIN and CORRECTION modes.
  • a so-called chronograph operation is characterized by a simple short press on one of the pushers, either residenceA or ⁇ B.
  • the circuit includes an oscillator-divider 31 connected to an external quartz 44.
  • the 1 Hz output of this divider 31 is connected, on the one hand, to a divider by sixty 32 and, on the other hand, to a chronograph counter 33
  • the output of the divider 32, delivering one pulse per minute, is connected through switches 34 and 35, on the one hand, to an hour meter 36 and, on the other hand, to a clock 37 intended to control a control circuit 38 of a motor M.
  • Counters 33 and 36 respectively output a bus A1 and a bus A0. Another bus B also leaves the motor control circuit 38.
  • the state of bus B is compared with the state of one of the buses A0 or A1, chosen by a switch 35 itself controlled by a selector C / H (stopwatch / hour) 39.
  • the comparison of buses A and B takes place in a comparator 40 whose output S controls a switch 41.
  • S takes the logic state 1 if the states of buses A and B are different and the state 0 otherwise.
  • the motor control circuit 38 receives a high frequency f q coming from the clock 37 and through the switch 41.
  • the motor M through a driver 43, is then driven at accelerated speed.
  • the control circuit 38 receives pulses whose frequency depends on the information displayed by the hands and determined by the selector 39.
  • Logical state 1 of the output of this selector is set to a few minutes (time period T1) by a timer 42 which itself receives pulses from the divider by sixty 32.
  • the timer is reset to zero either by the START / STOP 18 output or by the output GEL / SPLIT 19 from block 21 in Figure 3.
  • the output of selector 39 is in logic state 0.
  • part oscillator-divider 31 counters, divider by sixty 32, counters 33 and 36 are reset.
  • the output of the comparator 40 takes the logic state 1 and the control circuit 38 of the motor receives pulses f q , the hands 1 and 2 rotate at an accelerated speed and stop at any position.
  • the START / STOP 18 output controls the start or stop of the chronograph counter 33 as well as the timer 42 and consequently the selector 39.
  • the hands 1 and 2 then progress until indicating the information contained in the chronograph counter 33.
  • the GEL / SPLIT 19 output acts on the timer 42. It allows to change the reading mode and to pass from the time information to the chronograph information and vice versa.
  • the output 20 RESET CHRONO resets the chronograph counter 33 to zero and has the output of the selector 39 in logic state 1, which causes the hands 1 and 2 to rotate at accelerated speed until they are in zero position.
  • pressing button C allows you to enter the second time zone mode.
  • Double press on push-button A allows entering the time reset mode, but here the dividers are not reset and the STOP function is not performed.
  • Pressing push-button B causes needles 1 and 2 to rotate. Needle 1 makes one complete revolution while needle 2 advances by a twelfth of a revolution, or one hour. Pressing push-button B has no effect here.
  • pressing button C allows you to enter the alarm mode.
  • Pressing button A twice allows you to enter CORRECTION mode, but here the dividers are not reset and the STOP function is not controlled.
  • Pressing push-button B rotates the two hands 1 and 2 and thus displays the time chosen for the alarm according to the method described above.
  • Pressing push-button A causes rotation of hand 1 only and thus displays the minute chosen for the alarm using the same method.
  • the alarm mode is exited either by pressing button C, or automatically after a few minutes. Subsequently, the state of an alarm counter is compared at all times with the state of the hour counter 36 and at the coincidence of the states, an alarm output is activated by actuating a buzzer.
  • the determined time period TEMPO must have a duration long enough to allow the choice between arming or not arming the alarm. In a practical embodiment, an 8 second time interval has been adopted as reasonable. As already indicated, this period of time is provided by the TEMPO delay circuit preferably arranged in block 21 illustrated in FIG. 3.
  • FIG. 9 which supplements the diagram of FIG. 6.
  • FIG. 9 we have taken up certain elements appearing in FIG. 6 such as the switches 34, 35 and 41, the control circuit 38 and the motor driver M, the chronograph counter 33 and the hour counter 36 as well as the comparator 40, these times facilitating the understanding of the new diagram.
  • FIG. 9 has four new elements added to those of FIG. 6, which are an alarm time memory 48, a switch 47, a comparator 45, an AND gate 46 and a sound transducer SOUND.
  • the square terminals ALM and ARM are connected to the respective outputs 51 and 52 of the control circuit of FIG. 3.
  • bus A In alarm mode, bus A is in the position shown in FIG. 9, said bus A taking the value of bus A0.
  • ALM 1 and the switch 47 switches to the right so that the value of the bus A is identical to the value of the bus AO1 which is representative of the contents of the memory of the alarm time 48.
  • the motor control circuit or counter 38 will be loaded until the output S of comparator 40 is at logic value 1.
  • hands 1 and 2 display the alarm time contained in memory 48.
  • the content of the control circuit 38 can be modified by acting on the pushers as indicated above in paragraphs t) or w).
  • This content displayed by hands 1 and 2, will be found on bus B and therefore at the input of memory 48. It will be introduced into this memory when the alarm mode is abandoned, as explained above.
