Definitions

  • the present invention relates to clock mechanisms, also called timers, allowing the production of a warning signal after expiration of a time interval adjustable in advance.
  • Electromechanical timers are currently used in many applications, including kitchen timers integrated or not in cooking appliances, portable devices that remind the wearer of a given time (expiration time). a parking meter, for example) and other similar applications.
  • All of these timers generally include a time base establishing a constant reference period, a device for adjusting the time interval to be measured, the adjustment member of which is provided with a graduation calibrated in units of time, a generator device. an alarm signal and means for counting the number of reference periods included in said interval for, upon expiration thereof, controlling the triggering of said generator device.
  • the means for counting the number of reference periods are arranged as follows.
  • the time base is a quartz resonator which, via a dividing chain, can control a watchmaking stepper motor.
  • This motor is coupled to the adjustment member which is presented as a rotary disc and has a graduation calibrated in minutes, for example, and cooperating with a fixed reference.
  • This disc is integral with a cam associated with an inverter and provided with a notch which corresponds to the zero position of the disc, the inverter being closed in one direction for any position other than the zero position of the disc.
  • This inverter is electrically connected in the motor circuit so that as soon as the disc leaves the zero position, it is started to bring the disc back.
  • the generator device is actuated by the reverser in its other position when the notch of the disc is in front of it.
  • timer The disadvantage of this type of timer is that its accuracy is poor, because the angular position of the adjusting member which determines the duration of the interval to be measured is not clearly linked to the time value that this position is sensible represent. This is especially troublesome for short durations, it being understood that the maximum value of the scale is generally sixty minutes. If, for example, it is desired under these conditions to set a duration of the order of a minute, the angular deviation of the adjustment member is only a few degrees, which results in a delicate adjustment. In addition, such timers do not allow to set long durations, of the order of a few hours, for example.
  • the object of the invention is to provide a timer free from these drawbacks.
  • the adjustment device is of the step-by-step type and comprises a position transducer of said adjustment member, capable of generating an impulse signal whose number pulse is representative of the position of the adjusting member and, consequently, of the interval to be measured
  • the counting means comprise an accumulator circuit connected, on the one hand, to the transducer to be charged with the number of pulses produced by it and, on the other hand, at the time base for counting a number of periods thereof up to a value corresponding to this number of pulses, this accumulator circuit being also connected to the generator device to trigger the latter when said value is reached.
  • each step of the adjustment member always corresponds to a predetermined number of reference periods.
  • the ability to accurately measure small time intervals therefore depends only on the calibration of the adjustment device, each step of the adjustment member being able to correspond to any duration chosen by construction.
  • the invention makes it possible to envisage two alternative embodiments of the timer, one in which all the steps of the adjustment device correspond to an equal number of reference periods and the other in which each step can correspond to a different number (low or high) of these periods.
  • the timer is integrated into a timepiece of the wristwatch type, without however being linked to the mechanism or circuits which in this part ensure the indication of the official time, only the time base being able to be common to the two devices.
  • the electromechanical clockwork mechanism of which several embodiments will be described above can be used independently for the realization of a timer function or else be incorporated in a timepiece intended to allow the execution of this function. and indicate the official time. It is this second variant which is chosen in all of the examples described, but it will be understood that the invention is not limited to this sole use of the clock mechanism, the latter being capable of being produced independently, whether under shaped like a piece worn on the wrist or a table piece, for example.
  • FIG. 1 shows an overview of a first embodiment of the invention in which it is a wristwatch in which the following clockwork mechanism the invention has been incorporated.
  • a position transducer 1 which is essentially composed of two sub-assemblies, namely an adjustment member or indicator disc 2 and a switch 3, and which is associated with an adjustment assembly 4.
  • the indicator disc 2 replaces the date disc and that the adjustment set 4 is that which is usually used in a watch for adjusting the date.
  • the disc 2 is not driven by means of the clockwork, but remains independent so that the timer function of the assembly can be performed independently of the indication. of the official time.
  • the switch 3 is connected to a printed circuit 5 provided with an integrated circuit 6, the latter comprising not only the usual circuits necessary for the realization of the official time function, but also those which are required for the realization of the timer function, part of the integrated circuit 6 which will be described in detail in the description which follows.
  • the adjustment assembly 4 is designed exactly in the same way as an assembly, known per se, allowing the adjustment of the date disc, it is not necessary to give one here detailed description. It suffices to point out that the disc 2 is driven by an adjusting train 7 when the rod 8 of the watch is in its intermediate position, represented moreover in FIG. 1. Consequently, the rod 8 being in the position shown, it is possible to bring the disc into any one of 31 positions, this number being chosen as a function of the positions which are usual in a timepiece provided with a date indicator. However, it should be understood that this number is not limiting and depends in particular on the length and the distribution of the scale of the disc 2.
  • the disc 2 is therefore formed by an annular ring carrying on one of its faces indications which represent durations in minutes ranging from five minutes to five minutes.
  • the scale of disk 2 is here linear.
  • the inner periphery of the disc 2 is provided with a toothing composed of the teeth 9, on the one hand, and of a single notch 10, on the other hand, the numbers indicated on the disc appearing successively behind a window 11 provided in the rod area 8 and allowing the user to read the duration for which the timer is set.
  • the teeth 9 and the notch 10 cooperate with the switch 3.
  • the latter comprises a plate 12 fixed to the mechanism of the watch at 13 and provided with a contact arm 14 which also constitutes a jumper for positioning the disc 2.
  • This contact arm is electrically the movable contact of the switch 3 which also includes two fixed contacts 15 and 16 on which the free end of the contact arm 14 can be applied selectively, it being understood that this arm also has an intermediate position in which it is not supported on any of the contacts 15 or 16. It can be seen in FIG. 1 that the electrical contact is established between the arm 14 and the contact 15 when the elbow-shaped bearing portion 14a of the arm 14 is is housed in the notch 10 of the disc 2.
  • FIG. 2 shows another embodiment of the invention according to which, unlike the embodiment of FIG. 1, there is provided an indicator disc 2A not comprising a linear scale graduated in minutes and going from five minutes in five minutes, but a non-linear scale, i.e. starting with a fine division in a first zone 2A-1 graduated in one, three and five minutes, a second zone 2A-2 graduated in five minutes in five minutes, and a third zone 2A-3 graduated from quarter hour to quarter hour, up to a total of five hours.
  • an indicator disc 2A not comprising a linear scale graduated in minutes and going from five minutes in five minutes, but a non-linear scale, i.e. starting with a fine division in a first zone 2A-1 graduated in one, three and five minutes, a second zone 2A-2 graduated in five minutes in five minutes, and a third zone 2A-3 graduated from quarter hour to quarter hour, up to a total of five hours.
  • Figures 1 and 2 show the rest position of the timer, that is to say that the portion 14a of the contact arm 14 is supported in the notch 10, whereby the number 0 appears under the window 11. We admit for the moment that the electronic circuits of the timer are then off.
  • FIG. 3 represents the situation in which the disk 2A has been displaced by a half-step from the zero position by rotation of the rod 8.
  • the portion 14a of the contact arm 14 is therefore removed from the notch 10 for lean on the top of the first tooth 9 of the internal toothing of the disc.
  • the disc 2A After passing from the position of FIG. 3 to that of FIG. 4, the disc 2A again takes half a step, so that the portion 14a comes to be embedded between the first and the second tooth 9 of the disc 2.
  • the end of the arm 14 is not supported either on the contact 15 or on the contact 16, which constitutes for the electronic circuit significant information usable as such.
  • each pulse thus generated corresponds to a period of the same duration (five minutes), while in the variant of FIG. 2 certain pulses correspond to a short duration, while others correspond at a longer duration.
  • FIG. 5 represents a very simplified electrical diagram of a circuit which can be used in the watch shown in FIG. 1, that is to say that in which the disc 2 has a linear graduation.
  • This circuit which is that shown at 6 in FIG. 1, comprises a part 6A specifically intended for indicating the official time and a part 6B which performs the timer function in cooperation with the disk 2 and the switch 3 as well as the rod 8.
  • the part 6A comprises a quartz oscillator 17 supplying a signal whose frequency is approximately 32 kHz.
  • This oscillator is connected to a divider 18, one of the outputs 19 of which is connected to part 6B of the circuit, the signal appearing at this output being constituted by a train of pulses whose pulses are spaced five minutes apart (0.003 Hz) , at least in the example described here.
  • the divider is connected to a shaping circuit 20, itself connected to a stepping motor 21 driving the hands 22 of the watch, by means of a gear train.
  • the switch 3 is connected to an accumulator circuit 23 which, in this example, is a simple up-down counter, the counting input 24 being connected to the contact 16 of the switch, the down-counting input 25 to the output 19 of the divider and the zero output 26 to a warning device 27 providing an audible signal, or another similar signal, when the up-down counter 23 reaches the position 0.
  • This counter also includes a reset input 28 to which the contact is connected 15.
  • the warning device 27 is provided with a timing arrangement to ensure the production of an alarm signal for a certain time only after the up-down counter 23 has reached its position 0.
  • the operation of the circuit of FIG. 5 is as follows.
  • the user wants to use the timer to set a time interval to measure, he just has to place the rod 8 in the second position shown in Figure 1 and center the disc until the number corresponding to the desired duration in minutes appears behind the window 11.
  • the switch 3 has first left position 0 (fig. 1 ) to then control the up-down counter 23 at the rate of the passage of the teeth 9 in front of the portion 14a of the contact arm 14.
  • the up-down counter therefore recorded a certain number of pulses corresponding to as many five-minute periods which make up the time to measure.
  • the time base formed by the oscillator 17 and the divider 18 causes the content of the up-down counter 23 to be counted down at the rate of one pulse every five minutes, the period to be measured being ended when the up-down counter 23 reaches 0. It is at this instant that the alarm 27 acts to warn the user that the lapse of time has elapsed. In this case, the reference period used is therefore five minutes, this period being obtained at a particular output 19 of the divider 18.
  • the timer is completely independent of the official time indication which continues to be displayed completely separately, although the same time base is used in both cases.
  • Such a variant therefore expressly falls within the scope of the invention.
  • the disc 2 can advantageously replace the date disc without significantly changing the design of the timepiece itself.
  • the precision of the measurement of the time lapse ultimately depends on that of the time base which can be very good, that is to say that of conventional quartz watches. Indeed, the positioning of the disc 2 being ensured by steps thanks to the jumper and translated into a train of pulses, any pulse newly acquired by the up-down counter 23 will give rise to the establishment of a period of exactly five counted minutes by the time base 17, 18. The precision is therefore in no way dependent on the exact positioning of disk 2 and the user does not have to worry about it.
  • the adjustment disc does not have well-defined positions so that, especially for short time intervals, it is difficult to adjust it precisely to a position corresponding to the desired interval.
  • the adjustment of the position of the switch 3 relative to the disc 2 is not critical since the signal is obtained by means of the jumper formed by the contact arm 14.
  • a device for accumulating pulses which are generated when the disc 2A is rotated by means of the rod 8.
  • This accumulator device here comprises a counter 29 whose counting input is connected to contact 16 and whose output represents on several bits the number contained in the counter.
  • This output is connected in parallel to the address inputs of a permanent memory 30 which constitutes a scale transformation matrix. Consequently, the position of the counter 29 constitutes the address of this matrix which, in each of its bytes, stores a number corresponding to the duration of the time intervals to be measured. This number can be expressed, for example, in minutes or any other desired time unit. In this case, this unit is the minute.
  • each address of the memory 30 corresponds to a certain number of minutes, so that depending on the content of each of the bytes of the memory, it is possible to obtain a sort of "scale transformation” with respect to the successive steps.
  • the "transformation factor" can be arbitrary for each step of the disc 2A, because for each number accumulated in the counter 29 can correspond according to the previous programming of the memory any number of minutes to count down by the timer. This arrangement therefore provides great flexibility in producing the timer, the only limitation of the design being the number of steps that the disk 2A can take and the capacity of the counter 29 and of the memory 30.
  • the number of positions of this disc is advantageously 31, which allows the use of a disc whose construction is perfectly identical to that of 'a classic date disc apart, of course, from the inscriptions on it.
  • the data output from memory 30 is applied in the form of an eight-bit word, for example, to one of the inputs of a comparator 31, the other input, also of eight bits, is connected to a counter. 32 intended to receive counting pulses on its counting input from a divider circuit 33. The output of the latter provides a pulse every minute, for example. The corresponding pulses pass through an AND gate 34 for authorizing the passage of these pulses which are actually supplied by the time base of the timer.
  • the output of the comparator 31 is connected to an AND gate 35 for authorizing the passage of the signals controlling the alarm generator 27.
  • This AND gate is also connected to an oscillator 36 which is intended to supply a train of pulses to the device 27 , this train of pulses can give rise to an audible alarm signal of any kind, as is well known in the art.
  • the contact 16 in addition to being connected to the counting input of the counter 29, is also connected to the reset input of the divider 33, so that after the emission of each pulse by the switch 3, the counting down of the time period to be measured can start at the start of a minute.
  • the divider 19 providing a signal with a frequency of 0.5 Hz
  • the divider 33 divides this signal by 30, so that its output provides a pulse every sixty seconds.
  • Contact 16 is also connected to a first input of an OR gate 37, the other input of which is connected to the output of comparator 31 and the output of which is connected to the reset input of counter 32. The latter is therefore reset to zero either when the switch 3 emits a pulse, or when the comparator finds an equality between the content of the counter 32 and the data output of the memory 30.
  • the contact 15 is connected to the reset input of the counter 29 and also via an inverter 38 to a second input of the AND gate 34. In other words, when the disc is brought back to position 0, counter 29 is reset to zero and the pulses from the time base can no longer reach the counting input of counter 32.
  • the activation of the generator 27 of the alarm signal is subject to certain conditions.
  • the output of the comparator 31 which initiates the production of the warning signal is connected to a timer 39 with a duration of ten seconds for example which, via an inverter 40, is connected to the one of the inputs of the AND gate 35.
  • the latter is therefore only conducting during the duration of establishment of the timer 38, so that the signal from the oscillator 36 can only be transmitted to the generator 27 during this period.
  • the timer advantageously comprises a shock detector 41 incorporated in the case of the timepiece and providing a signal when the user applies a shock thereto.
  • the output of this detector is connected to the recovery input of a flip-flop 42 whose output is connected to a fourth input of the AND gate 35 and whose trigger input is connected to the output of the inverter 40.
  • This shock detector 41 is of the type to be activated by an activation input, which is achieved in the example described by means of a door 0U 43, a first input of which is connected by the 'through a timer 44 fixed at a few seconds at the output of comparator 31, the other input of OR gate 43 being connected to the 1 Hz output of the divider 18.
  • the detector 41 is activated periodically or an instant after finding by the comparator 31 of equality on its two inputs.
  • the example of FIG. 6 also includes a subtractor 45, a first input of which is connected to the output of the counter 32 and the other input of which is connected to the data output of the memory 30, so that this subtractor can establish at its output a number which is the difference between the number of minutes already counted down and the number of minutes to be counted down in full.
  • the output of the subtractor 45 can thus be connected to a decoder 46 connected to a device 47 for displaying the time which remains to be counted down.
  • This display device could be constituted by a liquid crystal display or any other similar system.
  • the example of FIG. 6 also comprises a second disc 48 arranged concentrically inside the disc 2A and bearing on its visible face below a part of the window 11 three indications corresponding respectively to the "stop", "1 x" and "repeat” function.

  • the movable contact 50 of this switch is connected to ground, while one 51 of the fixed contacts is connected to a inverter 52 and a fourth input of door 34.
  • this same signal resets this divider 30 to zero via the inverter 52, the counter 32 also being reset through this inverter and the OR gate 37.

  • the output of this same door is connected to the reset input d a flip-flop 55 whose trigger input is connected to contact 16 of switch 3.
  • the user To measure a period of time, the user first puts the rod 8 in the second drawn position (that is to say the one in which, in a conventional watch, it makes it possible to adjust the dates and the days). Turning the rod in one direction, the user moves the disc 48 to the "1 x" position, then turning the rod in the other direction, selects the duration of the lapse of time by observing the numbers scrolling behind the window 11. From that the spring 14 leaves the notch 10 (fig. 1 to 3), the reverser 3 leaves the contact 15 and, passing in front of the teeth 9, pushes its arm against the fixed contact 16, which results in the emission a number of pulses corresponding to the number of steps taken by the disc 2A. This number is recorded in the counter 29.
