Definitions

  • the present invention aims to achieve a display mechanism for all types of watch movements, in particular for wristwatches, larger than those known, thus allowing easier reading of a date indicator comprising units and tens.
  • This type of realization is mainly adapted for movements circular.
  • the aim of the present invention is to propose a solution allowing the display of a large calendar offering wide possibilities of implantation in a watch movement.
  • a date display mechanism of large size for time instrument through a window implementing a first digital support comprising the units and graduated from at least 0 to 9 and a second digital medium comprising the tens, the first medium describing at least an arc sweeping the decimals under the window according to the chosen time unit, characterized in that the second support numeric describes an arc of a circle whose center is placed outside the circle formed by the first support and whose tens digits are spaced by a non-obstructing area revealing the first support, this second support coming to be superimposed on the first support to form the two decimals of a number.
  • digital medium is meant a medium which can be of different shapes, for example a disc, sector or portion of a disc, on which is placed the desired graduation.
  • This graduation can be for the first support of units from 0 to 9, or a multiple of 0 to 9 twice if the place allows.
  • the wheel (1) is the PTO from the movement of base, which wears a finger (2) and goes around in 24 hours.
  • the wheel (1) meshes with the wheel (3) which carries an elastic finger (4).
  • the gear ratio between the wheel (1) and the wheel (3) is one so that the wheel (3) also makes a round in 24 hours.
  • the beak (4a) of the finger (4) thus drives the disc of the units (A) once a day which is provided with a star (5), integral, with 10 positions, from 0 to 9. This disc is locked by a jumper (6).
  • the wheel (1) also drives a wheel (20) also doing a tour in 24 hours wearing a solid finger (21) which each star causes a star (22) whose number of teeth is chosen by function of the number of tens to indicate, in this case 31.
  • This star is locked by a jumper (27).
  • This star carries a cam (23) integral comprising several rays (23a-23b-23c-23d) depending on the number of tens to indicate, in this case 4.
  • This cam is in connection with a sector (24) and is moved by its beak (24a).
  • the said sector is maintained in contact with the cam (23) by a spring (25).
  • the sector (24) drives by its teeth (24b) the tens sector (B) by its pinion integral (26).
  • the tens sector being superimposed on the units disc, it has spaces for reading unit numbers, as well as shown in Figures 1 and 2.
  • the mechanism comprises a star (30) driven a tooth a day by the finger (2) of the wheel (1).
  • Said star (30) has 31 teeth, locked by a jumper 31, it carries a finger (32) secured.
  • the mouthpiece (32a) of said finger, the 31st day based on the flank (33a) of the release lever (33) which pivots on its axis (34).
  • its side (33b) comes to press on the arm of the elastic spring (4) so that the beak (4a) cannot drive one of the teeth of the star 5 of the disc of the units (A) which therefore does not change position hence the maintenance of the number 1 of the units.
  • the drive disk is replaced by a drive sector (A ') with 10 positions from 0 to 9, also written on the same external radius that the tens sector, moved by a gear mounted in place of the discs of the units (A) of FIGS. 1 and 2 meshing by means of a oscillating pinion (40) which by a shape arranged in an arm of the sector units with the toothing of said sector of units (A ').
  • the pivoting of the unit area is located at any location in or at outside the mechanism.
  • the return to zero is effected by means of the declutching of the oscillating pinion at the end of travel of the sector, which is brought back under the action of the spring (50).
  • this invention also covers the display of texts or even the combination of texts and numbers.
  • the first disc could thus withstand the days of the week, and the industry could withstand the months.
