Definitions

  • the present invention relates to a date display device in particular for a timepiece of the type comprising a crown of units with the numbers 0 to 9 and a tens disc with the digits from 0 to 3, the date of the day being displayed in a large window by two figures arranged side by side, one being carried by the crown of the units and the other by the tens disk.
  • a date display device in particular for a timepiece of the type comprising a crown of units with the numbers 0 to 9 and a tens disc with the digits from 0 to 3, the date of the day being displayed in a large window by two figures arranged side by side, one being carried by the crown of the units and the other by the tens disk.
  • Such date displays are known from patent EP 0,529,191 or from Patent CH 689,601 both of which describe driven date displays by a mechanical watch movement.
  • the mechanisms of these two Known date displays are relatively complex and require several cogs of drive respectively a crown of the units to several superimposed teeth, which implies a space requirement in height important of these mechanisms.
  • the object of the present invention is to display a date display for a electro-mechanical clockwork movement which is simple, requiring little parts that are easy to machine and have a reduced overall height and whose reading is easy because of the large size of the figures.
  • Another object of the present invention is to provide a display of simple calendar, very readable, compact, which can be easily used for an annual or perpetual calendar.
  • the subject of the present invention is a date display known as "large counter ", obviating the drawbacks of existing devices, comprising a unit display unit provided with at least one series of numbers from 0 to 9 and one tens display unit comprising at least one series of numbers from 0 to 3, arranged in relation to each other so that a number of each of these organs can be displayed side by side in a window, these two organs units and tens being driven directly by each other, and which are distinguished by the features listed in claim 1.
  • the present date display device is of the "big date” type. that is to say comprising a body or crown of units 1 provided with a series of digits 0 to 9 or a multiple of this series of digits 0 to 9, and an organ or tens 2 disc with the numbers 0 to 3, or a multiple of this series of digits 0 to 3, arranged so that a digit can appear side by side of the crown of units 1 and a digit of the tens tens 2 in a single large window with a dial.
  • the display device which will be described below can equip any sort of watchmaking, mechanical, electrical or electro-mechanical movement, well that it is more particularly intended for the latter.
  • the display device according to the invention as illustrated in the drawing is consists of a unit display unit formed here by a crown of units 1 and a tens display member, here a tens disc 2.
  • the crown of the units 1 is provided with an internal toothing 3 engaged with a pinion 4 carried by the same pivot, and therefore secured to the tens 2 disc.
  • This pinion 4 meshes directly with the toothing 3 of the crown of the units 1.
  • This crown of units 1 is divided into ten sectors each carrying a digit of the units and therefore forming a series of digits from 0 to 9.
  • the sectors a bearing the numbers 0, 1, 2, 3, 4, 5, 6, 7 and 8 all have an equal arc length as well as an identical number of teeth of the internal teeth 3.
  • the number 9 of the crown of the units is it carried by a sector b of the crown of the units 1, sector b whose arc extent is greater than that of the sectors a and which therefore comprises more teeth of the toothing 3 than these sectors a .
  • each sector a of the crown of units 1 has eight teeth while sector b of this crown 1 has ten.
  • the pinion 4 of the tens disc has eight teeth, that is to say a number of teeth identical to that which comprise the sectors a of the crown of the units 1 bearing the numbers from 0 to 8.
  • the tens disc 2 integral with the pinion 4, bears so uniformly distributed on its circumference the figures from 0 to 3.
  • This disc of tens 2 is arranged in such a way that one of the digits it bears can be placed next to a number worn by the crown of units 1 so that these two figures can appear side by side in the same large window as has a dial not shown.
  • the date display described is driven by an electric micro-motor controlled by an electronic circuit, micro-motor driving either directly the axis 5 carrying the pinion 4 and the tens disc 2, or the axis 6 of a wheel 7 meshing with the internal toothing 3 of the crown of the units 1.
  • the wheel 7 may comprise any number of teeth, for example equal to an integer multiple of that of the pinion 4 or of the sectors a .
  • the drive of the crown of the units 1 is preferably done by the axis 5 the pinion 4 but the drive by the wheel 7 can be used in cases where for constructive reasons, or for size the micro-motor could not not directly drive axis 5.
  • the tens disc 2 performs a whole number of complete turns and that when the crown of the units 1 is displaced by an angular value corresponding to sector b , the tens disc performs an entire number of turns plus a quarter turn.
  • the disc of the units 2 performs one turn and the figure indicating the ten remains the same.
  • the tens 2 disc performs one and a quarter turns so that the number of the disc placed in the window next to a unit digit is incremented by one.
  • the number of teeth of the pinion 4 is equal or an integer multiple of the number of teeth that comprise sectors a of the crown of units 1 and that sector b of this crown 1 has 1.25 times the number of teeth of sectors a of this crown 1.
  • the number of teeth of sectors a and b of the crown of units 1 and the number of teeth of pinion 4 are such that when the crown of units 1 makes an angular displacement corresponding to one of its sectors a, change from a number 0 to 1; 1 to 2 ... 8 to 9, the pinion 4 and therefore the tens disc 2 performs one complete revolution or an entire number of complete revolutions.
  • the tens disc 2 performs a complete revolution and a quarter, or 5/4 of a turn so as to cause the passage from one tens digit to the next, or n. 5/4 of a turn.
  • the micro-motor which drives the pinion 4 or the wheel 7 is programmed to advance this wheel 7 or the pinion 4 by a value corresponding to the sector a , angular displacement of the crown of the units 1 by one day to the other and from sector b when passing tens. It is obvious that the electronic control circuit of the micro-motor can be provided to take into account the months of 28, 30 and 31 days, as well as leap years or secular years. It is thus easy to produce an annual or perpetual calendar display.
  • the micro-motor directly drives the pinion 4 secured to the tens 2 disc, it is controlled by its electronic control circuit so as to make a complete revolution, either 360 ° or 8 teeth in the illustrated case of the pinion 4, from the first to the ninth day of each month.
  • the micro-motor performs 1.25 turns, that is 450 ° or ten teeth of the pinion 4.
  • the displayed figure of tens remains the same while the figure of the units of the date displayed is incremented by one, the crown of the units 1 being driven by the angular value of a sector a , that is to say eight teeth in the example illustrated.
  • the tens 2 disc On the tenth day, the tens 2 disc performs 1 and a quarter turn and the displayed tens figure is incremented by one while the crown of units 1 is moved by an angular value corresponding to sector b , i.e. ten teeth in the example illustrated, and the number of units displayed changes from 9 to 0.
  • the micro-motor again drives the pinion 4 one turn per day then from 19 to 20 of a turn and a quarter .
  • the micro-motor again drives the pinion 4 for one revolution per day then from the 29th to the 30th for a revolution and a quarter.
  • the following days the micro-motor drives the pinion 4 by one turn and the date displayed is 31.
  • the micro-motor performs eight full revolutions bringing the date display to 39 then a quarter and a quarter bringing this display to 00 and finally another lap allowing display 01 in the dial window.
  • the micro-motor is driven on the 28th at midnight of a complete tour followed by a tour and a quarter then as for the months of 30 days.
  • the crown of the units 1 could comprise several series of digits 0 to 9, the sector b separating the digits 9 and 0 of each series being equal to 5/4 of the arc extent of the sectors a separating the others figures.
  • the display device which all have a crown of units with numbers 0 to 9 distributed in sectors of this crown, the sectors separating the digits 0, 1 ... 9 being of a arc length equal to 4/5 of the sector separating the digits 0 from 9 and a disk of tens performing one or more laps per day except for the tens jump where it performs one or more turns plus a quarter turn.
  • the disc of tens is integral with a pinion which is directly engaged with a toothing internal or possibly external of the unit crown.
