Definitions

  • the present invention relates to a timepiece with a calendar display with large format and instant jump including a time indicator train, a date mobile having a 31-tooth wheel, a wheel units of 30 teeth plus one space corresponding to a tooth for driving a pinion of the units of 10 teeth and a wheel of four teeth for driving a pinion of tens of 4 teeth, an annual cam secured to a wheel of 12 teeth, and drive means connected to said time indicator train for driving said date mobile by one turn per month and the annual cam one turn per year.
  • the object of the present invention is precisely to ensure that the timing mechanism of the timepiece allows a large format display in an instant jump calendar.
  • the subject of the present invention is a timepiece with a large-format display and instant jump, as defined by claim 1.
  • the calendar of this timepiece is a perpetual calendar and includes the display of days and months.
  • this calendar also includes an indication of the phases of the moon which is coaxial with an additional wheel for the indication of a second time zone, driven by the main indicator gear located in the center of the watch.
  • this timepiece calendar is intended to provide a clear display, easy to read, both as regards the layout of the elements displayed only with respect to readability, thanks to sufficiently large characters. All displayed indications change instantaneously and preferably do not require any correction, these being induced by the annual cam.
  • the figures 1 and 2 essentially show the calendar mechanism of the timepiece according to the present invention which comprises a drive wheel 1 integral with the cannon wheel or clock wheel RC, illustrated on the section of the figure 5 , meshing with a wheel 2 and making a turn in twelve hours.
  • the ratio between this pinion 2 and the Drive wheel 1 is 2/1, so that wheel 2 performs one turn per day.
  • This wheel 2 is integral with a cam 3 which works with a pin 4a integral with a rocker 4, pivotally mounted about an axis 4b.
  • This flip-flop 4 is divided into two arms, each of which terminates in a pawl 5a, 5b for the step-by-step training of a date wheel 7 of 31 teeth, respectively for stepwise driving of a star 8 ( figure 1 ) days of the week.
  • This flip-flop 4 comprises an opening in a circular arc 4c centered on its pivot axis 4b, in which a stop 4d is engaged.
  • This rocker 4 is pressed against one end of this opening 4c by a return spring 6 in engagement with a pin 4e of the rocker 4.
  • a second flip-flop 9, which constitutes a correction flip-flop, is pivotally mounted about the same axis 4b as the flip-flop 4. It is connected to the latter by an elastic arm 9a which bears against the peg 4a of the flip-flop 4, which makes protruding on both sides of this rocker 4.
  • the rocker 9 ends with a pawl 10 intended to selectively engage with a recess 11a of a correction cam 11, integral with the date mobile 7.
  • the date mobile 7 is still secured to two wheels, a drive wheel of the units 12, comprising 30 teeth and a gap corresponding to the 31 st tooth in engagement with a star 13 for displaying the date units, comprising 10 teeth.
  • the second integral wheel of the date mobile 7 is a tens 14 drive wheel, comprising 4 teeth engaged with a star 15 displaying tens of the dates.
  • Each of these stars 13, 15 is respectively integral with a concentric annular disc 13a of a disc 15a ( figure 1 and 5 ), the annular disc 13a bearing the numbers of the units from 0 to 9 and the disk 15a bearing the tens numbers from 0 to 3, the zero can be replaced by a blank space.
  • the date mobile 7 meshes in a 1/1 ratio with a wheel 16 integral with an instantaneous jump cam 17.
  • a rocker 18 pivoting about an axis 18a is pressed against the instantaneous jump cam 17 by a spring 19.
  • This latch 18 carries a driving pawl 20 which is engaged with an annual mobile 21 of twelve teeth, integral with an annual cam 22 which has sectors of variable radii representative of the number of days of the months of the year.
  • a portion 22a of this annual cam 22 is integral with a planet gear 23 ( figure 1 ) meshing with a sun wheel months 24 secured to the frame of the calendar mechanism.
  • the gear ratio between the planet pinion 23 and the sun wheel 24 months is chosen for this pinion gear 23 to turn for four turns of the sun wheel months 24.
  • the cam portion 22a has four sides, three of which are at the same distance from the axis of the pinion 23, while the fourth is at a greater distance than the other three.
  • the second flip-flop 9 comprises a probe arm 9b intended to come into contact with the periphery of the annual cam at each movement of the flip-flops 4 and 9, that is to say once a day. Since the different portions of the annual cam 22 have different radii depending on the length of the months, the amplitudes of the movements of the rocker 9 and its pawl 10 vary and the differences between the different amplitudes are absorbed by the elastic arm 9a of the flip-flop 9.
  • the annual mobile 21 is secured to a disc 21a bearing the indications of the twelve months of the year.
  • the mobile of the dates 7 and the annual mobile 21 as well as the star of the units 13 and that of the tens 15 are positioned angularly by respective jumpers, 25, 26, 27, 28.
  • One of the teeth of the annual mobile 21 has a thickness substantially greater than the other eleven teeth. With this thicker tooth, the annual mobile 21 causes a four-branched star 29 of a step per year. This star is secured to a reference 30 which drives a gear train 31, 32, 33, the last of which is secured to a star with four branches 34 in engagement with a jumper 35.
  • This star 34 is also integral with a disc 34a ( figure 1 ) bearing the numbers 1, 2, 3 and the letter B, for the indication of a cycle of four years including a leap year B.
  • the star of the day of the week 8 ( figure 1 ) is positioned by a jumper 41 and carries a disc 36 on which are displayed the days of the week.
  • This seven-pointed star 8 is engaged with a second star 37 also with seven branches positioned by a jumper 38.
  • This second star 37 is integral with a pinion 39 ( figure 1 ) which meshes with a reference 40 which meshes with a wheel 42 integral and coaxial with a wheel 43 which meshes with a wheel 44 for the indication of the phases of the moon.
  • the gear ratios of this gear train between the star of the weekdays 8 and the wheel 44 for the indication of the phases of the moon are chosen so that the wheel 44 makes a turn in three lunar months, in so that this wheel 44 carries three circles 45 representative of the moon, distributed at 120 ° to each other on the wheel 44 so that each of them serves to the indication of a lunar cycle in combination with an aperture (not shown) of suitable shape, formed through the dial C, to simulate the phases of growth and decay of the moon appearing in the window.
  • a third wheel 46 pivots on the same axis as the wheels 42, 43 of the moon phase gear train.
  • This third wheel 46 ( figure 1 ) carries a disc 46a divided into two sectors of 180 ° each, one being black and the other white to indicate the nocturnal hours and the daytime hours through a window (not shown) formed in the dial C of the room d watchmaking.
  • the wheel 46 meshes with a return 47 which meshes with a wheel 48 coaxial with the wheel 44 of the phases of the moon which meshes with the wheel 2 of the calendar.
  • These wheels 46, 48 and 2 have ratios 1/1 between them, so that the wheel 46 makes a turn in 24 hours as the wheel 2.
  • the black color appears through the window of the dial and the white color appears through this window during the next 12 hours.
  • the cam 3 integral with the wheel 2 of the calendar gradually lifts the latches 4 and 9 against the pressure exerted by the return spring 6 on the latch 4.
  • the pawls 5a, 5b are moved clockwise about the pivot axis 4b of the latches 4, 9, thus disengaging the teeth 7 and 8 and the finger 9b of the latch 9 more or less limits the pivoting amplitude of this flip-flop 9 according to the portion of the annual cam 22 which is in the path of the finger 9b and against which the finger 9b abuts.
  • the rocker 4 pivots with respect to the correction rocker 9, this relative pivoting of this rocker 4 with respect to the rocker 9 being absorbed by the deformation of the elastic arm 9a of this rocker 9.
  • the flip-flop 9 and its pawl 10 have no function, the pawl 10 sliding against the smooth surface of the correction cam 11 with each reciprocating movement of the flip-flops 4 and 9.
  • the pawl 10 engages behind the recess 11a of the correction cam 11, so that when the cam 3 releases the latches 4 and 9 to the restoring force of the spring 6, the pawl 10 drives the cam correction 11 of the value of two steps of the date wheel 7, integral with this correction cam 11, passing the date of 30 to 01.
  • the unit of the next 01 calendar does not change, only the ten changes. This is the reason why the date wheel 12 has 30 teeth and a space corresponding to a missing tooth.
  • the missing tooth of the date wheel is in front of the star of the units 13, so that it is not driven and that the number 1 is displayed two days consecutive. Only the star of tens 15 is driven one step by the wheel of tens to four teeth 14, passing the tens disk 15a from 3 to 0.
  • the annual cam 22 comprises a portion 22a integral with a planet gear 23 ( figure 1 ), which corresponds to the correction to be made at the end of February, which is either 28 days in a normal year or 29 days in a leap year.
  • This cam portion 22a is 1 ⁇ 4 turn each year and has four sides, one of which is located at a greater distance from the center of the planet pinion 23 than the other three.
  • the continuous movement of the wheel 2 in engagement with the drive wheel 1 integral with the RC gun wheel is communicated to the wheel 46 carrying the white / black indicating sectors of the day and night hours with a 1/1 ratio.
