Definitions

  • the present invention relates to clock modules comprising a display of the time by analog means and in particular by means of hour and minute hands which are carried respectively by an hour wheel and a floor, these two mobiles being mounted coaxially in the center of the module.
  • timepiece modules of this kind are generally driven by a stepping motor receiving its energy from a battery and the time base is constituted by an electronic device such as an oscillating quartz circuit. and a frequency divider.
  • a means of displaying the date recourse is in most cases to a display member of the type which has already been used in mechanical watches, ie .d. a date ring placed under the dial, the indications of which appear in a window arranged in the dial.
  • This date ring is driven by a jumping mechanism which gradually arms during the hours preceding midnight, so that the stepping motor which actuates the train encounters greater resistance during these hours than during most of it. hours of the day.
  • patent FR-A-2,416,503 proposes a switching wheel which is driven by the gear train and carries at its periphery one or more protruding contact elements intended to come into contact with corresponding fixed elements, once per revolution .
  • this arrangement has the consequence that the stepping motor driving the train is subjected to a variable torque due to the friction of the contact element. It is therefore necessary to build it in such a way that it can provide the maximum torque required, permanently.
  • Other date display devices also comprising a variable torque on the stepping motor are also described in the documents FR-A- 2,170,989, GB-A- 2,017,356, GB-A- 2,071,364 and DE-A- 2,925,278.
  • the object of the present invention is to provide another solution to the problem mentioned above, this other solution having the advantage of avoiding any risk of desynchronization between the date display and the time display and subjecting the constant torque stepping motor capable of regulating its progress.
  • the subject of the present invention is a timepiece comprising an electronic time base and a time display device with a stepping motor and a gear train, certain elements of which constitute organs of display, and on the other hand an electronic counting and date display means, characterized in that one of the elements of said gear train which is the slowest element comprises a disc made of insulating material which has a circular sliding surface and a metallic grounding contact element partially embedded in said surface, and in that the electronic date display means is connected to an elastic detector blade kept permanently in contact with the said sliding surface, the said blade acting on the one hand mechanically on the said gear element as a brake to eliminate the backlash and on the other hand electronically on the date display means for making advance the date indication displayed when it covers said contact element and is then grounded.
  • Fig.1 is a partially schematic top plan view showing a calendar watch in which the date is displayed by means of an electro-optical cell 21.
  • This watch includes as battery a battery 22 which supplies an electronic circuit 23 fixed to a printed circuit board 24.
  • the battery 22 further supplies a stepping motor 25, the rotor 26 of which drives a train consisting of elements 27, 26, 29, the element 29 being a minute wheel, the barrel of which can carry a central minute hand.
  • This minute wheel is engaged with a timer wheel 30, the pinion of which drives an hour wheel 31.
  • the barrel of this hour wheel can carry a usual hour hand, while its peripheral toothing drives a return wheel 32 the wheel teeth of which drive a 24-hour wheel 33.
  • the watch module shown in fig. 1 further comprises a control mechanism which can be operated by means of a crown 34 fixed to the end of a rod 35 disposed radially in the module.
  • the axial position of this rod is determined by a pull tab 36 of conventional construction held in place by a spring 37 which is cut in one piece with a rocker lever 36.
  • This rocker 36 controls on the one hand a sliding pinion 39 and d on the other hand a switch which is constituted by a movable contact element 40 situated at the end of the finger of the rocker and by a terminal 41 constituted by a metal blade, for example a gold blade cut and folded.
  • the base of this terminal 41 is welded to the board 24 at the location of a conductive track connected to the circuit 23.
  • the terminal 41 also has a tongue-shaped element which extends freely and the end of which is located opposite the contact element 40.
  • the rocker 38 has a notch 38a arranged so that when the rod 35 is pulled into an intermediate position (11), the contact element 40 and the sliding pinion 39 are moved towards the outside of the module and the contact element 40 touches the elastic tongue of the terminal 41. This terminal is then earthed.
  • cell 21 will be a liquid crystal cell, although other electro-optical systems may also be used.
  • This cell is mounted on a board 24 and its connection terminals (not shown) are connected to the circuit 23 by conductive tracks.
  • the 24-hour mobile 33 which is driven at an angular speed equal to half that of the hour wheel is shown in more detail in FIG. 3.
  • a metal disc 43 driven on a shaft 44 long enough to cross the dial of the timepiece described and carry at its upper end a 24-hour hand (not shown).
  • this mobile could also include a short shaft without an indicator member.
  • Under the disc 43 is fixed a lining 45 made of plastic, preferably Delrin, the periphery of which includes a groove 45a. At one point of its periphery, this groove is perforated and the rod of a pin 46 driven into a hole in the disc 43 projects slightly into the bottom of this groove.
  • the printed circuit board 24 extends below the mobile 33 and bears, opposite the groove 45a, a terminal 47 also consisting of a folded gold strip, so as to form a tongue with a V-folded end and engaged in throat 45a. Once per revolution of the wheel 33, the terminal 47 will therefore be earthed when the pin 46 comes into contact with its free end.
  • a terminal 47 also consisting of a folded gold strip, so as to form a tongue with a V-folded end and engaged in throat 45a.
  • this watch is as follows: a quartz 48 fixed under the printed circuit board 24 controls a frequency divider whose output pulses control, at a stable frequency, for example 1 Hz, the drive of the motor.
  • the circuit 23 further comprises a counter and a decoder which control the cell 21 from the pulses which the counter receives at each revolution of the wheel 33 when the contact element 46 is connected to the terminal 47.
  • the decoder is arranged to so as to cause the digits 1 to 31 to appear successively on cell 21.
  • the date jump being controlled by contact 46/47, it will always be synchronized with the position of the hands and will occur each time at midnight.
  • the correction of the date takes place electronically when the rod 34 is in position II. Indeed, the closing of the contact 41/40 commands in the electronic circuit 23 the emission of pulses, for example at a frequency of 1 Hz but only beginning two seconds counted from the closing of the contact and these pulses at a frequency of 1 Hz are transmitted to the decoder so that the day numbers scroll on cell 21 at the frequency of 1 Hz. Similarly, if the time is set by means of the crown 34, making pass the hands through the midnight position, automatically a pulse will be given to the date decoder which will advance the cell by one.
  • the counting of the pulses supplied by the contact 46/47 will be arranged so that when the contact element 46 comes into contact with the blade 47, a first pulse is recorded and the recording of other pulses is blocked for all the time during which the contact element slides under the blade 47. This avoids false impulses which could result from rebounds of the blade 47 on the contact element 46.
  • the details of the circuit arrangement which allow only receive the first recorded pulse, are known per se and it is not necessary to describe them here.
  • the contact blade 47 presses against the mobile 33 not only while the pin 46 is facing its tip, but also throughout the duration of the rotation of this mobile. It indeed presses against the bottom of the groove 45a and acts as friction, which eliminates gear sets.
  • the blade 47 therefore serves to regulate not only the rotation of the mobile 33 which triggers the date change at precise midnight, but also the rotation of the other indicator mobiles, in particular the hour wheel 31 and the minute wheel 29.
  • the hour wheel 31 could be shaped like the mobile 33 and carry a pin moving in the path of a contact blade such as the contact blade 47.
  • the mobile 33 and the mobile 32 could be deleted.
  • the electronic circuit is conformed so that the change of date is only ordered once in two under the effect of the pulses resulting from the closing of the contact 46/47.
  • the mobile 33 would rotate at the same speed as the mobile 31 and the circuit should be arranged so as to control the date change only once on them.
  • Fig.3 shows an embodiment in which the date display means are different from those provided in the embodiment according to fig.1, all the rest of the elements of the module being also the same.
  • These display means comprise a motor 49, the construction of which may be the same as that of the motor 25, but which, as will be seen later, could operate slightly differently.
  • the rotor 50 of this motor drives by its pinion a date switching mobile 51, the finger 51 of which engages in the toothing 52a of a date ring 52, which may be of usual construction.
  • This ring is placed under the dial and carries on its upper surface the indications of the dates from 1 to 31. Its toothing is also 31 teeth and it is held in place normally by means of a jumper spring 53.
  • a window which can being located for example at three o'clock, or at noon, allows one to see one of the calendars carried by the ring 52.
  • the electronic circuit 23 commands a series of predetermined pulses to be sent to the motor 49. These pulses can follow one another at a relatively high frequency and cause the rotor 50 to rotate so that the mobile 51 performs a full turn on itself. During this rotation, his finger 51a a will engage in the toothing 52a and advance the date ring 52 by one step.
  • the frequency of its operation can be relatively high and its drive torque can be low, since the drive is direct.
  • the resistance torque which it must overcome at each pulse to drive the train is very low and on the other hand perfectly regular. Thus, the torque of this motor and the duration of its pulses can be adjusted to minimum values, which contributes to saving the energy of the battery 22.
  • the 24-hour wheel 33 is always synchronized with the hours and minutes, even when the time is corrected by the sliding pinion 9 and the crown 34. It is therefore the 24-hour wheel which controls and guarantees the change of date and not an electronic circuit whose programming remains complex.
  • the rod 34 is pulled into a position 11 which closes the contact 40/41.
  • the circuit 23 then controls the motor 49 continuously, so that the date indications scroll through the window.
  • the motor 49 could also cause a calendar mechanism with calendar and days of the week comprising a day star, as well as, in the form of execution described in relation to FIG. 2, cell 21 could also include a moven for displaying the day of the week.
