Definitions
- the present invention relates to an analog timepiece comprising means for warning of a change of mode.
- the present invention relates to a timepiece with several operating modes, of the type described in patent application EP-A-0 476 425.
- the timepiece described in this document indeed includes, in addition to the normal operating mode, known as the hourly operating mode since providing the hour and the minute, an additional operating mode which can be activated by the user, by manipulation on the stem.
- This operating mode makes it possible to adjust the hands in a time reference position different from the conventional reference, in which the two hour and minute hands are superimposed at noon.
- This operating mode known as the time reference adjustment mode, makes it possible to fix the time reference position marking the zero hour-zero minute opposite any mark on the dial.
- a classic timepiece such as a watch
- a watch for left-handed people that is to say with the time-setting crown on the left, and no longer on the right.
- Document US-A-4 223 522 describes an analog watch comprising hour, minute and second hands. If the user of this watch introduces another mode of operation, the second hand, after having been brought to a determined position, is put into a state of oscillation from this position.
- This oscillation of the second hand should signal a change in mode, but in fact, this movement is confusing for the user, because an oscillation of a hand usually indicates the end of life of the battery (EOL, " end of life ").
- this oscillation of the second hand causes a large load on the drive motor and its shaft, due to the acceleration and inertia of the second hand.
- document EP-B-0 175 961 concerns the correction of the time in a universal watch, minute by minute or by entire time zone, in the same position drawn from the rod, by the choice of speed of rotation at which the crown is driven. Again, the change in operating mode is not signaled.
- the present invention aims to provide a timepiece having several operating modes, such as a mode for adjusting a time reference, and comprising effective warning means, but of simplest and least expensive design possible.
- the present invention therefore relates to a timepiece with analog display having at least two selectable operating modes, a first said timetable and a second said non-timetable, and comprising at least one hour hand and one minute hand which can be independently operated by means motors, electronic means for managing said operating modes and a control member capable of acting on said management means, this part being characterized in that it comprises means for visual warning of entry into the mode of non-hourly operation, and in that these warning means are formed by said hour and minute hands and consist of a complete rotation of said two hands, after these have been brought back to respective initial positions of time reference .
- said complete rotation is a simultaneous rotation of the two hour and minute hands, at the same speed, in a constant relative position.
- said simultaneous rotation is a rotation of the hour and minute hands in a superimposed configuration of said hands.
- the invention comprises at least one so-called warning register, linked to the management means, this register comprising a value representative of a number necessary for the complete rotation of at least one needle.
- FIG. 1 there is shown in Figure 1, in the form of a block diagram, a timepiece constituting an embodiment of the present invention.
- This timepiece includes in series a quartz oscillator 2, a division chain 4 delivering a signal at 1 Hz, a seconds counter 6 providing a minute signal and in particular forming a digital indicator of the position of the hand of the seconds (not shown), and a counter 8 essentially forming a digital indicator of the position of the minute hand m.
- the timepiece according to the invention further comprises a divider by twelve referenced 10, receiving the output signal from the second counter 6, and a counter 12, called the hour counter, forming a digital indicator of the position of the hour hand h .
- the hour counter 12 receives information from the latter every twelve minutes.
- the counters 6, 8 and 12 are counters by sixty whose operating mode is shown diagrammatically in FIG. 4.
- the pulses used for the incrementation are received by the counter 6, 8, 12 upstream (on the left in the figure). These successive pulses are counted by a binary counter 40 of at least six bits, which they increment.
- This counter 40 is linked to a divider by 60 referenced 42 which supplies the output pulses and which initializes the counter 40 every 60 pulses (Reset).
- the counters 8 and 12 respectively define, in normal operating mode, the angular position of the minute hands m and the hour hand h on the dial of the timepiece by relative to the time reference position. Since the timepiece described here does not include a second hand, the second counter 6 is only used to provide a minute signal and to increment the other counters 8, 12.
- the timepiece according to the invention is furthermore provided with two motors 18 and 20 controlled respectively by power circuits 14 and 16, for driving the minute hand m and the hour hand h respectively (FIG. 2) .
- the circuits 14 and 16 receive, in normal operating mode, the pulses applied respectively to the inputs of the minute counters 8 and hours 12.
- motors 18 and 20 and their associated gear train are shaped to advance the minute and hour hands by one step of a 60 th turn receiving a control pulse from power circuits 14 and 16.
- the counter 8 has, in binary form, a value between 0 and 59 (with an initialization at 60) directly representative of the angular position of the minute hand m .
- the h hours of needle may also move from 60 th round in steps, with each pulse, she spends an hour mark to another five steps at a rate of one step every twelve minutes, thanks to the divider by 12 referenced 10.
- the counter 12 records, in normal operating mode, each movement of the hour hand h and includes, in binary form, a value between 0 and 59 (with a initialization at 60) directly representative of the angular position of the hour hand h .
- the timepiece according to the invention further comprises electronic management means 22, called adjustment means, allowing in the described application to modify the position of the corresponding time reference by definition at the zero of the minute hand position and at the zero of the hour hand position), in an operating mode additional, known as non-hourly operating mode or time reference adjustment mode.
- electronic management means 22 called adjustment means, allowing in the described application to modify the position of the corresponding time reference by definition at the zero of the minute hand position and at the zero of the hour hand position), in an operating mode additional, known as non-hourly operating mode or time reference adjustment mode.
- These electronic management means or adjustment means 22 comprise inputs MN and H for receiving the contents of the minute counters 8 and hours 12, an activation input EN and an input D of data for movement of the hands towards the forward and backward.
- the signals applied to the inputs EN and D are supplied by an interpretation circuit 24 capable of interpreting and providing information relating to the position and the displacement (direction and speed) of the control rod (not shown).
- the operation of the control rod and of the interpretation circuit 24 are already known from document EP-0 175 961 and will therefore not be described here in detail.
- the electronic management means 22 also include two outputs Mmn and Mh for delivering pulses to the motors 18 and 20, and a control output C for managing the state of the two switches 26, 28 arranged at the input of the power circuits 14 , 16 and arranged to transmit to them, either the pulses applied to the inputs of the position indicators of the minute hand 8 and hours 12 when these switches are in a first position referenced a , or the pulses delivered by the electronic means of management 22 when these same switches are in a second position, referenced b .
- the electronic management means can advantageously be produced in the form of an integrated circuit comprising a programmed microcontroller. Those skilled in the art will know, from the indications provided here, to carry out the programming of the microcontroller, so as to make it execute the functions described.
- the electronic management means 22 are also advantageously associated with two hour 29 and minute 27 registers, comprising two numbers Rh and Rmn, in binary form, which, in a preferred embodiment, are chosen to be equal.
- the electronic management means 22 are inactive and the motors 18, 20 receive the pulses applied to the inputs of the position counters of the minute and hour hands 8, 12.
- the activation of the electronic management means 22 is obtained, for example, by a particular manipulation of the control rod which causes the emission by the interpretation circuit 24 of an activation signal towards the input EN of the means management 22.
- the management means 22 then successively execute, in this new operating mode, an initialization phase, an alert phase, an adjustment phase, possibly an additional alert phase, then a display phase
- the initialization function is activated for example by pushing on the stem with a pressure maintained for a determined time (step B).
- the displacement of the rod causes the transmission by the interpretation circuit 24 (FIG. 1) of a signal towards the input EN of the electronic management means 22.
- the electronic management means 22 then emit a signal at their output C to place the switches 26 and 28 in state b .
- the electronic management means 22 read the content of the counters 8 and 12 to know the respective positions of the minute hands m and hours h .
- the electronic management means 22 then transmit, in a preferred embodiment, the number pulses required on the outputs Mmn and Mh to bring the hands m and h , via the power circuits 14, 16 and the motors 18, 20, to the time reference position defined previously, that is to say that 'they would have if the contents of counters 8 and 12 were equal to zero (this does not affect the operation of counters 6, 8 and 12).
- only one of the needles is moved, and this by emitting a signal only at one of the outputs Mmn or Mh, the other needle remaining fixed in position.
- the electronic management means 22 take the content (values Rmn and Rh) of the or registers 27 and 29 and transmit, always at the outputs Mmn and Mh, the number of pulses corresponding to the number Rmn and / or Rh contained, in binary form, in the register (s) 27, 29.
- the numbers Rmn and Rh contained in the registers 27 and 29 being advantageously both equal to 60, the hour and minute hands , in a preferred embodiment, both move by a corresponding number of steps, and they perform together at the same speed a rotation of 360 °, that is to say one revolution of the dial, to return at their predetermined time reference position.
- the concomitant rotation of the hands is carried out in this superimposed form.
- warning means consist of a complete rotation of at least one needle , after it has been returned to its initial time reference position.
- the warning means consist of a simultaneous rotation of the two hour and minute hands, at the same speed, in a constant relative angular position, for example in superposition .
- warning means apply advantageously to the indication of entry into an operating mode, such as the change of time reference, since the specific movement of the time display hands over a complete revolution and in the same direction clearly indicates a significant change in the time display.
- the user defines in this phase the new position of the time reference by marking, using the hands d 'hours h and minutes m , the position chosen for this new time reference.
- the movement of the hands is controlled by the control rod, the movement of the latter being interpreted by the circuit 24 which sends corresponding pulses to the input D of the management or adjustment means 22 which, in turn, emit on the outputs Mmn and Mh of the control pulses to the motors 18 and 20.
- the needles remain constantly superimposed.
- the management means 22 or the user send the same pulses to the two motors 18 and 20. This allows the user to better realize that the timepiece is in adjustment mode. .
- the management means 22 When the user has marked the new position desired for the time reference, he leaves the adjustment mode by a particular manipulation of the control rod.
- the management means 22 then read the contents of the minute counters 8 and hours 12, which define the current time, and send the corresponding number of pulses to the motors 18 and 20 to move the hands from the reference position to the display position of the current time.
- step A a timepiece here forming a wristwatch intended to be worn on the left wrist.
- the control rod is therefore on the right.
- the dial is fitted with four different indexes at 12, 3, 6 and 9. The minute and hour hands each make 60 steps per revolution of the dial.
- noon and midnight are marked by the superposition of the hands at 12 o'clock. This position is chosen as the time reference.
- the current time is therefore 10h 11mn.
- the content CPmn of the minute counter is thus equal to 11, and the content CP H of the hour counter is 50.
- step B When the user enters the adjustment mode, as shown in step B, the two hands move until they are in the time reference position (initialization phase). They then overlap at 12 o'clock.
- step C the alert phase is implemented automatically by the warning means.
- the values Rmn and Rh of the registers 27 and 29 are taken into account by the electronic management means 22 which supply a corresponding number of pulses (here 60) to the motors 18 and 20.
- the two hands h and m then perform a complete rotation, preferably at high speed, in a superimposed configuration to warn the user of the entry into this operating mode which is here a non-hourly operating mode. At the end of this rotation, they find themselves in their time reference position which has not yet changed (step D).
- step E the new desired position for the time reference, by marking this position with the hands (adjustment phase) using manual intervention on the crown.
- the new position of the time reference is chosen at 6 o'clock by the user.
- the management means 22 move the hands (display phase) so that they display the current time taking into account the new position of the time reference by advancing each hand by a number of steps equal to the contents of the corresponding counter (step F).
- an alert phase is implemented before returning to the display of the current time to warn the user that he has left the adjustment mode.
- the wristwatch can now be worn on the right wrist with the control rod on the left. Adjusting the position of the time reference allows the two hands to be superimposed when it is noon or midnight.
- the time reference is indicated, in the adjustment phase, by the position of the superimposed hands, which is also their position during the rapid movement to 360 °, in the alert phase. It is clear that in order to be able to superimpose the hands and move them together, the watch movement must include two independent motors, one for each hand.
- the position of a needle determined to mark the position of the time reference.
- the adjustment means can be provided with a table containing a limited number of positions authorized for the time reference.
- This table is preferably filled in the factory by the manufacturer of the timepiece.
- the possible positions are the four positions which in a normal watch indicate 3h, 6h, 9h and 12h.
