Definitions

  • the present invention relates to an electronic timepiece comprising a time base equipped with a quartz and a frequency divider, a time display device which itself comprises a motor, driven hands by the motor and a dial above which the needles move, a counting device comprising an electronic circuit, and a manual control device making it possible to control the switching on, the tripping and the return to zero of the said device (s) chronograph hands.
  • the object of the present invention is to improve electronic timepieces capable of displaying a counting function in order to simplify the control of the counting needles and in particular the return to zero function.
  • the timepiece according to the invention is characterized in that the counting device comprises several motors in that a chronograph hand is associated with each motor of the counting device, and in that the manual control device comprises switches acting on the circuit so as to control the said counting motors.
  • the timepiece shown in the drawing externally has the appearance of a wristwatch. Its case 1 is connected to a bracelet 2. It carries four pushers 3 mounted on the sides of the box and allowing the control of counting devices, as will be seen below.
  • a dial 4 In the visible face of the watch described, appears a dial 4. In the center of this dial rotate an hour hand 5 and a minute hand 6. A usual hour turn is printed on dial 4.
  • the first counting device comprises a liquid crystal cell 8 formed with two display positions 8a and 8b which respectively display the tens and the units of hundredths of a second.
  • a second counting device designated by 9 and which has a circle with second marks. In the center of this zone, the dial is crossed by an axis on which a 10 seconds hand is mounted.
  • a circular display area 11 and a hand 12 having the same arrangement as the elements 9 and 10 are arranged over 7 h and, as will be seen later, these display elements constitute the visible part of a minute counter . This can be graduated from 0 to 60 or from 0 to 100 depending on the forms of execution.
  • the display device described has a dial area 13 and a hand 14 which are capable of functioning as a time totalizer.
  • Fig. 2 makes it possible to understand the arrangement and the functioning of the internal elements of the timepiece described.
  • a battery 15 housed in the housing 1 excites the various functional elements of the watch.
  • a quartz 16 constitutes the pilot element of a time base whose electronic elements are concentrated in an integrated circuit chip 17. This comprises, not only the oscillator which excites the quartz 16, but a frequency divider which supplies a time base signal at a standard frequency, for example a frequency of one Hz, this signal being shaped so as to be able to excite one or more stepping motors.
  • cell 8. This is supplied by pulses from a decoding circuit also incorporated in the chip 17 and controlled at a frequency of 100 Hz when the counting device is operating.
  • Different outputs of the circuit 17 further supply three drive mechanisms designated by 18, 19 and 20. These three mechanisms are mounted in a fixed frame and arranged so as to drive the needles 10, 12 and 14 respectively described above. The constitution of these mechanisms will be described below in more detail.
  • the movement of the chronograph watch described comprises a drive mechanism 21 which is placed in the center of the housing 1. It is a conventional stepping motor which drives a gear train itself comprising a timer wheel, a minute wheel, and a hours. These last two wheels are coaxial and have cannons engaged one inside the other. These cross the dial 4 and carry the hands 5 and 6 which move above the marks 7.
  • Fig. 3 shows diagrammatically, but with a little more detail, the drive mechanism 18.
  • the motor proper comprises a coil 22 mounted on an elongated core 23 whose ends form lateral tabs 23a and 23b connected to pole pieces 24 and 25 which embrace a rotor 26 fitted with a pinion 27.
  • the motor is shown here schematically.
  • the rotor 26 can make a half-turn at each step or turn by a predetermined angle but less than 180.
  • the pinion 27 drives a gear made up of two elements 28 and 29 engaged with each other so as to drive a central shaft 30 which carries the needle 10.
  • the mechanisms 19 and 20 are constituted in exactly the same way as the mechanism 18. Their operation is determined by the frequency of the signals feeding the coil 22, this frequency being supplied by the output of the circuit 17 to which the coil is connected.
  • FIG. 2 there is shown diagrammatically four push button switches 31, one of the contacts of which is connected to an input of the circuit 17.
  • One of these push buttons controls the engagement of the counters. These will be started simultaneously and will thus make it possible to count hundredths of seconds, seconds, minutes and hours up to a totalization value which can be set at will.
  • the same push-button, or another can control the stop of the counting, its restarting with or without leap, as well as the return to zero, that is to say the recall of all the hands to the 12 o'clock position as seen in the drawing. While these functions are engaged, the function of the mechanism 21 is not modified, so that the hands 5 and 6 continue to indicate the exact time.
  • One of the push buttons 3 can be used to make, if necessary, the corrections of the position of hands 5 and 6.
  • the control device is also designed so as to display at will, in cell 8, another indication than the hundredth of a second, for example the date, the number of the month or even the year.
  • this cell could also include a display with three positions or with more than three positions. It could be used to display data other than the indications listed above.
  • the circuit 17 includes counter circuits whose state constantly corresponds to the position of the chronograph hands.
  • the motors of mechanisms 18, 19 and 20 receive a number of pulses such that hands 10, 12 and 14 quickly return to the midday position.
  • cell 18 receives the control signals necessary to display the indication 00.
  • control device may also include a control rod equipped with a crown and capable of moving in rotation around its axis and to be drawn axially, these displacements controlling switches connected to the circuit.
  • the different counting devices which are arranged separately in the embodiment described could also be assembled so that, for example, the needles 12 and 14 are coaxial.
  • the timepiece can be made as a wristwatch, pocket watch or the like.
