Definitions

  • the object of the present invention is to produce a date display mechanism large format for all watch movements, in particular watches and clocks, allowing an easy reading of the date, whose construction is simple since it requires and combines a reduced number of parts and mobiles.
  • This invention also aims to reduce the volume (in particular by reducing height) of the above-described mechanism and render it, once the mobiles are pre-assembled easily adaptable to all existing watch movements with a traditional date indication by crown, since this mechanism can be driven by the date crown of the movement of the watch concerned which will be modified accordingly.
  • the subject of this invention is a large format date display mechanism for all movements of watches and clocks to achieve the above-described goal and comprising the characteristics defined in claim 1.
  • the mechanism firstly comprises a programmed crown 1 intended either for replace the original crown of date 2, or to be fixed on this crown of original date 2.
  • This programmed crown 1 that is 1/2, has a toothing 4 composed of four teeth.
  • the programmed crown 1 includes, just like the date crowns usual, the inscription of a series 3 of 31 figures arranged tangentially, i.e. figures 1,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4 , 5,6,7,8,9,0, distributed uniformly which are intended to indicate the units of the date.
  • the programmed crown 1, i.e. 1/2 does not include no digit representing the tens
  • a kinematic chain drives this crown 1, or 1/2, at the rate of one step per day at from the hour wheel of the watch movement (plane A) to perform a complete rotation in 31 days.
  • This training is discontinuous and the step takes place around midnight each day.
  • This programmed crown 1, or 1/2 could also be driven by a stepper motor (quartz movement) and a gear driven by this motor, motor piloted by an electronic movement timekeeper.
  • Plan C consists of a plate 5 surrounding the programmed crown and intended for be fixed to the watch movement (plan A).
  • This plate 5 comprises a light in an arc of a circle 6 allowing the passage of the date crown (1 or combination 1, 2 of the programmed crown), platinum which is fixed to the watch movement by screws 7.
  • This mechanism includes a dozen mobile.
  • the tens mobile is composed of a star 8 with four branches or teeth, a indented tens display disc 9 having on its upper surface numbers from 0 to 3 arranged tangentially and evenly distributed.
  • a jumper 11 is fixed to the plate 5 by an axial screw 12 and comes into contact with the branches of the star 8 located at the same level to keep blocked the parts angular between two successive actuations.
  • a locking spring 13 is fixed to the plate 5 by an axial screw 14 and maintains the jumper between two successive actuations.
  • the tens 8/9 mobile is entirely dependent on the programmed crown 1, or 1/2.
  • the mechanism is provided with a dial 15 pierced by a large window 16 with 2 windows of a dimension, in principle minimum 2 x 4 mm, dial covering the entire mechanism and is fixed using feet 17 (4 in number) on the plate 5.
  • the tens disc 9 advances by one step every ten days of so that the number corresponding to the tens of the date appears in the window 16 of the dial 15 next to the numbers of the units 3 arranged on the crown programmed 1, i.e. 1/2.
  • the tens disc rotates completely in one month.
  • This mechanism makes it possible to have the large window 16 of the dial 15 in numerous points of the dial surface 15 provided that the two display discs are symmetrically fixed on each side of an axis so that the tens and the units meet and be displayed respectively to the left and right of the tangent.
  • topological implantation of the mechanism, object of this invention allows a variation of layout of the window going on an open angle between 11H and 1H on the top of the dial and on an open angle between 5H and 7H on the bottom of the dial.
  • the mechanism has a very limited number of parts and only three mobiles (two mobiles on plane D and one mobile on plane B). It can be fully assembled and pre-shown on plate 5 with the exception of the programmed crown 1 which is place on the movement.
  • the plate is then equipped with the dial which will allow display of the large date calendar.
  • the window 16 is twice as large as that of a conventional window
  • the volume of the mechanism is very low which allows adaptation on all the currently existing movements providing for the date display.
  • the object of this invention is to manufacture and produce a movement of watches or clocks provided with a mechanism for displaying the large format calendar as described above.
