Definitions

  • the present invention relates to a display mechanism for a timepiece and in particular a simple or perpetual calendar display mechanism, preferably a display mechanism making it possible to display the date, the day of the week and the month.
  • optical magnifying means such as a magnifying glass
  • the units and tens digits are distributed on separate mobiles and the size of these digits can then be considerably enlarged.
  • the document CH 310 559 describes for example a date display, in which the date is indicated by two juxtaposed or coplanar disks, one bearing the tens digits, the other the units digits. Other arrangements of the units and tens disks are possible.
  • the documents EP 0 529 191 And EP 1 070 996 describe a date display with a units disc and a tens disc superimposed.
  • the documents CH 690 515 , DE 102005010602 And CH 688 671 describe a date display with a coplanar and coaxial units disk and tens disk.
  • the aim of the present invention is therefore to produce a display mechanism, in particular a date display mechanism, comprising two coplanar display disks, and which overcomes the above drawbacks.
  • a particular aim of the present invention is to produce a display mechanism which makes it possible to display the date, the day of the week and the month on a single line in a single window as large as possible and without superimposing disks.
  • the present invention relates to a display mechanism according to claim 1 and a movement and a timepiece according to claims 10 and 11 respectively.
  • the present invention relates to a display mechanism intended to equip a movement of a timepiece.
  • the display mechanism makes it possible to display the date, the day of the week and the month.
  • the illustrated display mechanism comprises a tens indicator 11 and a units indicator 12, together forming a date display, as well as a days of the week indicator 13 and a months indicator 14.
  • the tens indicator 11 is shaped like a crown and bears the series of numbers 0, 1, 2, 3 repeated five times counterclockwise.
  • the 12 units indicator is also crown-shaped and bears the series of numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, repeated twice counterclockwise.
  • the date display is of the "large date" type and therefore allows the use of indications of a reasonable size to facilitate reading.
  • the weekday indicator 13 and the month indicator 14 are disc-shaped and bear respectively seven indications for the days of the week and twelve indications for the months of the year, distributed in a clockwise direction (the usual English abbreviations are used as indications in the figures).
  • the tens indicator 11 and the weekday indicator 13 are coaxial and coplanar, the tens indicator 11 surrounding the weekday indicator 13.
  • the units indicator 12 and the month indicator 14 are also coaxial and coplanar, the units indicator 12 surrounding the month indicator 14. surrounding that of the months 14.
  • the four indicators 11, 12, 13, 14 are arranged to be coplanar. It is thus possible to display the day, date and month on one line and in a single large window.
  • the weekday indicator 13 is carried by a weekday disc 130.
  • the weekday disc 130 is arranged to pivot relative to a first fixed ring 15, coaxial with said weekday disc 130 and fixedly mounted on the plate or a bridge of the movement.
  • the weekday disc 130 pivots inside the first fixed ring 15 by means of a first ball bearing (see Figures 5a and 5b ) in which a first series of balls 161 are kept regularly spaced by any suitable means (cage) between the disc of the days of the week 130 and the first fixed ring 15.
  • the tens indicator 11 is carried by a tens ring 110 mounted coaxially with the disc of the days of the week 130 and with the first fixed ring 15 and arranged to pivot relative to said first fixed ring 15 by means of a second ball bearing (see Figures 5a and 5b ) in which a second series of balls 162 are kept regularly spaced by any suitable means (cage) between the tens ring 110 and the first fixed ring 15.
  • the arrangement of the units indicator 12 and that of the months 14 is similar.
  • the months indicator 14 is carried by a months disc 140.
  • the months disc 140 is arranged to pivot relative to a second fixed ring 17, coaxial with said months disc 140 and fixedly mounted on the plate or a bridge of the movement.
  • the months disc 140 pivots inside the second fixed ring 17 by means of a third ball bearing (see Figures 5a and 5b ) in which a third series of balls 163 are kept regularly spaced by any suitable means (cage) between the month disc 140 and the second fixed ring 17.
  • the units indicator 12 is carried by a units ring 120 mounted coaxially with the month disc 140 and with the second fixed ring 17 and arranged to pivot relative to said second fixed ring 17 by means of a fourth ball bearing (see Figures 5a and 5b ) in which a fourth series of balls 164 are kept regularly spaced by any suitable means (cage) between the ring of units 120 and the second fixed ring 17 holder.
  • the four ball bearings formed firstly by the weekday disc 130, the first fixed ring 15 and the first series of balls 161, secondly by the first fixed ring 15, the tens ring 110 and the second series of balls 162, thirdly by the month disc 140, the second fixed ring 17 and the third series of balls 163, and fourthly by the second fixed ring 17, the units ring 120 and the fourth series of balls 164, make it possible to replace the sliding friction (of an axis between two bearings or stones, or of tubes interacting with each other) by the rolling friction between the weekday disc 130, the tens ring 110 and the first fixed ring 15 and between the month disc 140, the units ring 120 and the second fixed ring 17.
  • the display mechanism according to the present embodiment is arranged to drive the units ring 120 (units indicator 12) thirty times per month (no drive when changing from 31 to 01 see below) and the days of the week disc 130 (days of the week indicator 13) once per day, the tens ring 110 and the tens indicator 11 four times per month and the months disc 140 (month indicator 14) once per month.
  • the tens ring 110 carries an external toothing 111 for its drive of four steps per month via a dedicated kinematic chain of the display mechanism and a positioning toothing 112 cooperating with a jumper 113 for its angular positioning.
  • the ring of the units 120 also includes an external toothing 121 for its drive of thirty steps per month via a dedicated kinematic chain of the display mechanism and a positioning toothing 122 cooperating with a jumper 123 for its angular positioning.
  • the disk of the days of the week 130 is attached to a star of the days of the week 30 comprising seven teeth arranged to be driven one step per day by a dedicated kinematic chain of the display mechanism and whose positioning is ensured by a jumper 31.
  • the 140 month disc is also attached to a 4 month star with twelve teeth and designed to make one turn per year.
  • the positioning of the 4 month star and therefore of the 140 month disc is ensured by a 41 month jumper.
  • the display mechanism according to the present embodiment automatically takes into account the length of the months (28, 29, 30 or 31 days), the transition from 31 to 01 at the end of the month and leap years. It is therefore a perpetual calendar display mechanism.
  • the display mechanism described above may further include a correction mechanism to enable the displayed date, day of the week and month to be corrected.
  • the display mechanism described above allowing the display of the date, days of the week and months, and what is more in a perpetual manner, is an example of an embodiment of a display mechanism according to the invention.
  • the display mechanism according to the invention could be a simple, annual or secular calendar or a display of the week number or even a chronograph counter or more generally a mechanism display allowing the display of a single piece of information in a single window or of several separate pieces of information in at least one window.
  • the embodiment illustrated above is in fact the combination of several variants of the invention: in fact, the units indicator and the tens indicator are coplanar and juxtaposed and pivoted relative to each other by means of two ball bearings and cooperate together to display a single piece of information (the date) in the same window; while the tens indicator and the day of the week indicator are coplanar and coaxial and pivot relative to each other by means of two ball bearings also to display two separate pieces of information (tens of the date and day of the week) in the same window.
