Description

The present invention relates to analog displays.

  logic for watch movement and more specifically-

  ment it consists of an analog display device or module intended to be integrated or fixed, instead of a usual dial, on a watch movement and

  which includes a time indication mechanism with ai-

  guilles in the center cooperating with a concentric circular graduation, this mechanism being driven by the clockwork movement.

  The display device according to the invention is

  tingue in that it includes an analog display of the nu-

  week number with a circular week graduation of fifty-two or fifty-three divisions

  cooperating with a benchmark. This display device comprises

  also carries a weeks mechanism causing a

  relative movement between the coordinate system and the corresponding graduation

  laying weeks, relative movement constituted by one complete revolution per year; this weeks mechanism

  also being driven by the watch movement.

  The appended drawing illustrates schematically and by way of example several embodiments of a display device according to the invention, in the form of a module intended to be fixed to the movement of a

  The exemplary embodiments given below relate to

  all surround display modules intended to be displayed

  tees on a watch movement in place of the case

  dran. It is obvious that the invention can also be

  performed as part of a clock movement-

  mechanical or quartz. Indeed, the affi-

  chage can either be integrated into a timepiece, wristwatch, pocket watch, chronograph, pendulum etc., mechanical or quartz, or be designed as an independent module that can be mounted or fixed on a

  mechanical or quartz watch movement in a

  mountable and interchangeable to form a timepiece

  gerie. In its first, simplest embodiment, the analog display module illustrated in FIGS. 1, 5

  and 6 has a dial 1 and a time display

  with a divided graduation 2 around the circumference of the dial

  in sixty minutes and twelve hours cooperating with ai-

  guilles in the center, concentric with graduation 2,

  hours 3, minutes 4 and seconds 5. This display module

  file also includes, in known manner, a switch

  conventional ensuring the driving of the needles

  count 5 and minute 4 from an hour wheel 8 of the module, secured to the hour hand 3. This wheel - 4 -

  8 hours is driven by a power take-off

watchmaking.

  The originality of this display module lies in the

  design of an analog display of the number of the

  maine, from 1 to 52 or 53, in a year. This display includes

  carries an eccentric circular graduation 6, placed in the upper part of the dial, between its center O and 12 o'clock,

  in the example illustrated, comprising fifty-two divi-

  sions representing the fifty-two weeks of the year.

  This graduation cooperates with a 7 week needle

  making a complete revolution in a year. This ai-

  guille 7 and this graduation 6 are driven in their relative movement by a mechanism of weeks also

  driven by the PTO of the watch movement.

  In the illustrated case the fixed graduation 6 is carried by

  dial 1 while the week hand 7 is in

  dragged by the weeks mechanism from the wheel

8 hours of the display module.

  Such a display of the week number is very

  useful especially for all people dealing with

  manufacturing, delivery or ordering. Indeed it is more and more usual to indicate such delays,

  either in number of weeks or by indication of the number

  weeklong week or weeks delimiting these deadlines.

  Having the indication of the nu-

  mero of the current week is therefore for these people

  an additional convenience that will quickly become

  dispensable and will replace the calendars currently

used to be done.

-5-

  In variants this display of the number of the

  maine could be constituted by a disc mounted rotating under the dial provided with a graduation of 52 or 53 divisions cooperating with a reference constituted by a window practiced

in dial 1.

  The mechanism of the weeks allowing in this embodiment the driving in rotation of the needle 7 by successive steps numbering fifty-two or fifty-three for a complete revolution in one year

is illustrated in Figures 5 and 6.

  The PTO of the movement is constituted by an axis carrying out a revolution in twelve hours driving

  the module hour wheel 8. Depending on the form of execution

  tion, we use one, two or three PTOs of the watch movement which allow the drive of

  all mechanisms of the display module, information mechanism

  hour indication, week mechanism, or any other method

  canism as we will see below, the indication of the quan-

  tith, of the day of the week, of the moon phases or of

  dragging chronograph counters. All of these

  nisms of the analog display module are mounted between a plate 9 and the dial 1 of the module using one or more bridges 10. The plate, the bridge (s) 10 and the

  dial 1 are integral and constitute the framework or the

  mature carrier of the module which is fixed amo-

  visible on a watch movement.

  The week mechanism includes an intermediate mobile

  diary pivoted on the plate 9 whose wheel 11 meshes with the hour wheel 8 and whose pinion 12 is engaged with a reference 13 pivoted between the plate 9 and the -6 bridge 10. This reference 13 carries an actuating finger 14, having seen in plan the shape of a truncated circle sector, integral with a pin 15 driven into said reference 13. With this mounting the angular position of this

  finger 14 relative to reference 13 can be adjusted per-

  setting the instant when this finger 14 enters

  contact with one of the teeth of the star of seven 16 pivo-

on the plate 9.

  This star of seven 16 performs a revolution com-

  completes in seven days and carries a wheel 17 engaged with a mobile 18 having the same number of teeth as the wheel 17, pivoted on the bridge 10, carrying a disc 19 provided with an index 20 arranged in an opening 21 of the dial 1 This

  index 20 cooperates with a graduation 22 carried by the case

  dran, concentrically to disc 19 and needle 7, in-

  saying the seven days of the week. So with each step of the star of seven, that is, every twenty-four hours,

  index 20 goes from one day to the next.

  This indication of the day of the week 20,22 is concentric with the graduation of weeks 6 and located at

inside of it.

  The week 7 hand is carried by the axis of a wheel 23 of fifty-two teeth, pivoted in the plate 9

  and inside the mobile 18. This wheel of fifty-

  two respectively fifty-three teeth 23 is driven by successive steps at the rate of one step per week by a beak

  24 of the hub 25 connecting the star of seven 16 to the wheel 17.

  To avoid any untimely movement of the star of sept 16, a jumper 26 maintains it in its angular position between two actuations. Similarly, a jumper 27 -7 cooperates with the teeth of the wheel 23 to keep it in its angular position between two actuations and

  avoid any untimely angular displacement.

  Thanks to this mechanism we drive from the wheel

  hours 8 the weeks hand 7 allowing

  dear number of the current week and simultaneously,

  in this example, the display of the day of the week 20.22.

  The same mechanism could be used to drive

  ner a rotating disc with a graduation of 52 or 53

  divisions would cooperate with a window of dial 1.

  In variants, this mechanism of weeks for-

  should be dragging, that is to say that the indicator member, needle or disc, would be driven in continuous rotation at

because of one revolution per year.

  As will be seen later in the description of the

  second embodiment of the module, the hour wheel 8 is driven from a first PTO of the

watch movement.

  In this simplest form of execution, the affi-

  time zone as well as the hour wheel 8 of the module

  are driven by a single PTO of the movement.

  In this case the module includes a convention switch-

  nel. You can also drag the second hand to the center 5 and the minute hand to the center 4 directly

  by the second axis respectively the roadway of the

  the hour wheel 8 by the hour axis of the

  movement. In this case the switch is part of the movement

  ment and the module is driven by it using three PTOs. Such training would be

  also used in a variant or the display device

- 8 -

  file and its mechanism would be integrated into the timepiece

  house. This mechanism also includes a day of the week corrector constituted by a lever 28 pivoted at 29 on the

  plate 9 and subjected to the return action of a spring 30.

  This correction lever 28 has a pusher 31 accessible

  visible from outside the watch case and its ex-

  free end cooperates with the teeth of the star of seven

  16 to turn it step by step under the action of the push

evening 31.

  To avoid damage to the mechanism during

  correction of days, finger 14 can be mounted

  voting on pin 15 and subjected to elastic action

  to keep it in the active position

  sirée but allowing its retraction during the action-

  ment of the star of sept 16 by the correction lever 28.

  This mechanism also includes a correction lever 32

  tion of the week number. This lever 32 is also pivoted on the plate at 29 and is provided near

  one of its ends of a pusher 33. On the other ex-

  end of this lever 32 is pivoted a pawl 34 whose free end is in engagement with the teeth of the wheel 23. The pawl 34 is provided with a leaf spring 35 in abutment

  against a pin 36 of lever 32. To correct the nu-

  user of the week press on push button 33

  placing the lever 32 as far as against a stop 37. This does

  sant the pawl 34 jumps a tooth from the wheel 23 and comes

  in engagement with the previous tooth thereof while ban-

  in the leaf spring 35. When the user releases the push-button

-9-

  evening 33, the leaf spring moves the lever 32 and the

  quet 34 until the lever 32 is again in abutment against the stop 38. In doing so, the pawl 34 moves

  the wheel 23 by one step. It should be noted that judgment 38 is

  adjustable thanks to an eccentric allowing to define

  the end position for correcting the lever 32.

  It is obvious that in a variant the display 14,20 of the day of the week can be suppressed without modifying anything in the mechanism of the weeks driving the hand 7. Similarly, the display of the number of the week could be concentric to a other indication such as the date, the moon phase etc. As will be seen below, this mechanism of weeks can be combined in a chronograph display module, with calendar and / or indication of the phases of

  moon or any other display desired. Whatever the com-

  display module, it includes either a

  conventional switch or a display mechanism ho-

  for the time display as well as a week mechanism as described above as an example for

  display of the number of weeks in the year.

  Figure 6a illustrates a variant of the mechanism of

  weeks. In this variant, the gear train causing the

  cloth of seven and the wheel of fifty-two weeks is identical to that previously described, only the organs

correction are changed.

  This mechanism includes a corrector for the days of the week constituted by a lever 200, provided with a pusher 201 accessible from outside the module, pivoted at 202 on

  platinum. This lever 200 is subjected to the action of a res-

- 10 -

  return spell 203 tending to keep it in abutment against a stop 204. This correction lever 200 comprises an actuating spout 205 acting on the teeth of the star of seven to cause it to advance step by step. The race of

  corrector 200 is limited by the stop 218.

  This mechanism also includes a correction system

  the indication of the number of the weeks. This system

  carries a week corrector 206 also pivoted at 202 G on the plate and comprising a pusher 207 accessible from outside the module. This corrector 206 has a bearing face 208 cooperating with the end 209 of a rocker 210 pivoted at 218 on the plate. This lever 210 is subjected to the action of a return spring 212 tending to keep it in abutment against the stop 204 cooperating with a

opening 213 of this rocker 210.

  An oscillating pawl 214 is pivoted on the other ex-

  end of rocker 210 at 215. A spring 216 formed in one piece with the pawl 214 tends to apply

this one against a stop 217.

  When the user presses the push-button 207 it pro-

  voque the tilting of the rocker 210 and the pawl 214 drives the weeks wheel. The stroke of the rocker 210 is limited by the coming into contact on the opposite side of the opening 213 with the stop 204 so that the weeks wheel can only be driven by one step for each

actuation of the pusher 207.

  In the embodiment illustrated in Figures 2,7 and 8, the display module previously described provided with

  its hourly display and day of the week displays

  maine and the number of the week as well as their mechanics

- i1 -

  my training is combined with a display of chr

  nographer driven by a chronograph train and ac-

  operated by a chronograph control mechanism.

  As seen in Figure 2, the time display includes the hour 3 and minute 4 hands

  center as well as a second eccentric second hand 41 cooperated

  rant with a 40 seconds graduation. The chronograph display is original and has three counters; a concentric second counter with a hand

  seconds chronograph 5a cooperating with the gradua-

  tion of minutes 2 of the time display; an ex counter

  centered ten minutes comprising a graduation 42 of ten divisions cooperating with a minute chronograph hand 43; and an eccentric hour counter comprising a graduation 44 of thirty divisions, staggered by ten

  in ten minutes, cooperating with a chronograph hand

45 hour graph.

  The originality in this chronograph display lies in the fact that the minute counter cycles

  complete in ten minutes and the hour counter has

  carries a graduation, extending over several hours, from one to six for example, but comprising subdivisions of

  ten minutes corresponding to the minute counter cycle.

  The chronograph train illustrated in FIGS. 7 and 8, driving the second hand 41 of the time display and the hand 5a of the second counter in one revolution per minute, the hand of the minute counter

  43 in one revolution in ten minutes and the needle of the

  45 hour counter in a three hour revolution

- 12 -

  carries a wheel 46 mounted frictionally on the seconds axis

47 of the display module.

  This wheel 46 meshes with the first wheel 48 of a reference 49 including the second wheel 50, of the same number of

  teeth that the wheel 48 is engaged with the wheel 51 solidly

  Daire of the axis 52 carrying the second hand 41. This wheel 51 has the same number of teeth as the wheel 46. The reference 49 also has a clutch allowing the function

stop-start of the chronograph.

  The axle 52 carries a second wheel 70 driven, by

  via an intermediate wheel 71, by a pre-

  better PTO of the movement. This PTO is constituted by an axis carrying out one revolution per minute carrying the wheel 72. This wheel 72 has the same number of teeth as the wheel 70, thus the axis 52 as well as the axis 47 are driven at the same speed that this wheel

  72, a complete revolution in sixty seconds.

  The wheel 46 which drives the seconds axis 47 of the display module is also engaged with the wheel 54 of an intermediate mobile 53 whose pinion 55 meshes

  with a wheel 56 of a mobile whose axis 57 carries the

  43 minute chronograph watch.

* The pinion 58 of the mobile 56,57 meshes with the wheel 59

  a mobile 60 whose pinion 61 is engaged with a pre-

  mier reference 62 driving, via a second reference 63, the wheel 64 whose axis 65 carries the needle

45 hour chronograph.

  All the chronograph train is mounted between the

  plate 9 and the bridge (s) 10 of the display module.

- 13 -

  The display module also includes a conventional type chronograph control mechanism comprising a stop-stop push button 66 controlling a friction clutch function acting on the reference 49 and a

  positioning function of the reference 63 allowing its de-

  coupling with the mobile 64 and a reset push button 67 acting by means of hammers and hearts on axes 47, 57 and 65. This mechanism

  command, for example of the type described in the short-

  vet CH 661.409 but of course adapted to the layout of the chronograph counters in this module, will not

  described so as not to overload the drawing and the description

of this patent.

  The interest of this original chronograph display

  is to allow an easy fast reading especially many

  easier hit for minutes and hours than is the case with thirty-minute and twelve-hour counters as so far. In addition, it is rare to time a duration of more than three hours so that having an hour counter limited to three hours is not a drawback. Anyway we can without

  interfere with the ease of reading the pre-

  see a four or six hour graduation; it suffices to modify the mobiles 90 and 93 accordingly so that the needle 85 rotates in four or six hours.

  In the two embodiments previously described

  as in the next third embodiment, the hour 3 and minute 4 hands of the time display are driven from one second

- 14 -

  PTO of the movement constituted by an effective axis

  killing one revolution per hour and carrying a wheel 73 (FIG. 10) engaged with the first wheel 74 of a reference 75. This reference 75 has a second wheel 76, identical to the wheel 74, which meshes with the road or wheel of minutes 77 and a pinion 78 which meshes with the wheel of

8 hours.

  In the first embodiment of the module, the center seconds axis could also be driven to

  from reference 75, therefore from the same PTO 73.

  On the other hand, in the second and third forms of execution

  The display module requires two power take-offs, one 73 for driving the hour 3 and minute 4 hands in the center as well as for driving the week mechanism, and the other 72 for driving the second hand 41, the hand of the seconds counter in the center 5a and the hour and minute counters of the chronograph. The third embodiment illustrated in Figures 3, 9 and 10 of the analog display module is similar to the second in that in addition to the time display and

  display of the day of the week and the number of the week

  maine and corresponding mechanisms, it also includes

  a chronograph display, a chrono cog

  graph for driving the chronograph counters and an on-off and reset control mechanism

chronograph zero.

  The time display includes a graduation of the

  eccentrics 80 divided into sixty seconds and one

  second hand 81 making a revolution in one minute.

- 15 -

  The chronograph display includes a minute counter with a graduation 82 of thirty divisions cooperating with a minute hand 83 performing a

  revolution in thirty minutes; and an hour counter

  with a scale 84 from one to twelve, subdivided into

  half hours, cooperating with an 85 ef- hour hand

  making a revolution in twelve hours.

  This chronograph display also includes a seconds counter comprising a seconds hand in the center cooperating with the graduation of the minutes.

time display.

  The cog of this chronograph is, as in the se-

  this embodiment driven by a power take-off 72

  driving the intermediate wheel 71 then the mobile 52 carries

  as the second hand 41, then as described above the second counter wheel 46 via the

mobile 49 (see Figures 7, 8 and 9).

  Referring to Figures 9 and 10 now we see that the wheel 46 drives the mobile 86 whose axis carries the needle 83 of the minute counter through

  a first mobile 87, a second mobile 88 and a

see 89.

  The wheel of the mobile 86 in turn drives the mobile 90, the axis of which carries the hand 85 of the hour meter by

  via a mobile 91 and two references 92,93.

  This display module also includes a chronograph control mechanism of the same type as that used in the second embodiment comprising a button.

  on-off push-button 94 controlling the function of

  clutch acting on the friction of the wheel 46 on its axis

- 16 -

  47 and a reset button 95 acting through the

  mediator of hammers and hearts on the axes of mobiles

  47, 86 and 90. This mechanism, although original in its reali-

  sation is conventional in design and does not

will not be described in detail here.

  The fourth embodiment of the analog display module illustrated in FIGS. 4 and 11 to 14 includes a time display with hands in the center driven by

  a watch movement in a conventional manner; an af-

  week number with a circular graduation, concentric to the time display, of fifty-two or fifty-three divisions cooperating with

  a needle making a revolution in one year

  dragged by a weeks mechanism; a date display and a day of the week display both

  eccentric and comprising a graduation of the dates

  pectively of the day of the week cooperating with a-

  guille each carrying out a revolution in one month-

  pectively in a week driven by calendar mechanisms respectively for the day of the week; and finally a display of the moon phases, the disc of which is driven by a moon mechanism. As will be seen in this embodiment, all of the above mechanisms are housed

  between a plate 100 and the dial 101, the assembly

  killing an interchangeable module that can be mounted on, and

  driven by a movement to form a clock piece-

laughs.

  The time display device comprises on the ca-

  dran 101 a sixty minute graduation 102 and hourly hour markers 103 concentric to the module and cooperating

- 17 -

  respectively with a second hand 104, a help

  105 minute hand and 106 hour hand.

  In this embodiment, the module is driven by three PTOs of the movement, the second hand 104 is driven by the seconds axis 107 of the movement; the minute hand 105 is driven by the carriageway 108 of the movement and the hour hand is driven

  by the hour wheel 109 of the movement.

  The hour wheel 109 is integral with a pinion 110 constituting, as will be seen below, the power take-off

  for all other mechanisms of the display module.

  The day of the week display has a graphic

  duation 111 of seven divisions indicating the day of the se-

  maine cooperating with a needle 112 performing a revo

  lution in seven days. This needle 112 is carried by a star of seven 113, secured to a hub 114 pivoted in the plate 100, whose angular position is defi

  denies by a long necklace 115. This star of seven 113 is in-

  drag at a rate of one jump per day from the pinion 110 carried by the hour wheel 109 by means of a wheel 116 carrying a rocking pawl 117 driven by this wheel 116 using a pin 118 cooperating with a light 119 of the pawl 117. This pawl 117 comprises a

  beak 120 cooperating with the teeth of the star of sept 113.

  A day of week correction lever 121 is pivoted on the plate and subjected to the action of a return spring 122. This lever comprises a pusher 123 accessible from outside the module and a spout 124 causing

  movement of the lever 121, the advance of a step of the

  canvas of sept 113. Thanks to the connection by pin 118 and

- 18 -

  light 119 of the pawl 117 on the wheel 116, a correction of the angular position of the star of sept 113 can be done even if the beak 120 of the pawl is engaged with a tooth of this star of sept 113 without driving the wheel 116 .

  The moon phase display includes a

  section 125 in the dial 101 revealing a

  tion of a moon disc 126 carrying the representation of the moon in a conventional manner. This moon disc 126

  makes a revolution in twenty-nine days.

  Its angular positions are maintained by a

  roof 127. The drive of this moon disc 126 is red

  traced from a pin 128 of the pawl 117 cooperating with the teeth of a reference 129 meshing with a wheel itself engaged with the peripheral teeth of the

moon disc 126.

  A moon corrector 131 is pivoted on the plate

  and subjected to the action of a second arm of the spring 122.

  This corrector 131 includes a pusher 133 accessible from outside the module and a spout cooperating with the teeth of the wheel 130. Here also the pawl drive

  117 using the pin 118 and the light 119 per-

  puts a moon correction at all times, also when the pin 128 is engaged with the teeth of the

  return 129 without causing rotation of the wheel 116.

  The mechanism driving the hand 134 of the date display opposite the scale 135 includes a wheel 137, engaged with the pinion 110, as with the wheel 116 of an oscillating pawl 138 driven by this wheel through a pin 139 located in a light

  140. The beak 141 of the pawl 138 actuates a star of

  thirty-one 142 whose hub carries the needle 134.

  A corrector lever 143 is pivoted on the plate

  and is subjected to the action of a return spring 144.

  This lever comprises a pusher 145 accessible from the outside.

  laughing module and a beak 146 cooperating with the star

thirty-one 142.

  A jumper 147 fixes the successive angular positions

  sives of the star of thirty-one 142.

  The week number display has a graphic

  duation of fifty-two divisions 148, concentric with the

  graduation 102 of the time indication, located outside

  laughing at the latter and cooperating with a needle 149 performing one revolution per year. In the example illustrated, this display also includes an indication of the months located outside the scale of weeks 148. The hand of weeks 149 is carried by a barrel

  151 secured to a week wheel 152 rotated

  tion at the rate of one revolution, that is to say fifty-two steps, in one year by means of a nipple 153 carried by a wheel 154 engaged with a wheel 155 secured to the hub of the star of sept 113. De this way the wheel of weeks 152 is driven step by step at the rate of one step per

  week. Its successive angular positions are deter-

  mined and maintained by a jumper 156.

  The week mechanism still has a correction

  teur 157 pivoted on the plate 100 comprising a pusher

  158 accessible from outside the module and the end of which

  mite 159 cooperates with the toothing of the week wheel

  also appreciable help for the user before work-

1st with deadlines.

  Note that in this execution the module is driven by three power take-offs from the movement, one driving the seconds hand in the center 104, the

  second driving the 105 minute hand and the third

  sith driving the hour wheel 109. It is this hour wheel 109 which by means of its pinion 110

  drives all mechanisms and displays other than the af-

  time display module. It is also interesting to note that the wheels 116, 137 and their

  117,138 pawls are identical which simplifies the fa-

brication and reduces the cost.

  Of course, another variant of the display module could be produced in which certain displays such as that of the date, moon phases or day of the week would be eliminated. The simplest version has a time display with hands in the center and

  a display of the number of the week also with ai-

guilles in the center.

  In another variant one could provide ai-

  conventional guiding in the display module so that only a PTO is required which can be

  formed by the seconds axis or the movement floor

watchmaking.
