Definitions

  • the present invention relates to timepieces with a display of calendar. It concerns, more particularly, based on the same principle, a manual date corrector mechanism for single date and one automatic date correction mechanism for perpetual calendar.
  • the date mechanism makes it possible to indicate the date of the month by means of a pointer moving on the dial or a rotating disk under the dial and revealing its indications through a window.
  • This kind of system is well known to those skilled in the art and is described in detail, for example, in the book “Théorie de l'horlogerie” by Reymondin et al, Federation of Technical Schools, 1798, ISBN 2-940025-10-X, pages 189 and following.
  • the indicator of date, disk or needle is actuated to from the hour wheel, by means of the date wheel whose last element is a thirty-one wheel performing a turn in thirty-one days advancing 360/31 ° every twenty-four hours, towards midnight.
  • the date wheel whose last element is a thirty-one wheel performing a turn in thirty-one days advancing 360/31 ° every twenty-four hours, towards midnight.
  • a needle display it is mounted in solidarity with rotation on the shaft of this wheel.
  • this one is driven by a finger attached to the wheel of thirty-one.
  • a toothed wheel called a cam
  • the cam has depressions whose depth is correlated with the length of the months.
  • the cam has forty-eight or twelve sectors, depending on whether the mechanism takes into account years leap.
  • the present invention has for first purpose to propose a corrector of simple calendar allowing to simply program the correction of the date display any day of a month under thirty-one days and return it on the last day.
  • the second object of the invention is to provide a date mechanism perpetual without the usual cams and flip-flops.
  • the mechanism according to the invention is intended to take place in the movement a mechanical or electro-mechanical watch with date display.
  • the realization of this function being perfectly known to those skilled in the art and not specifically the object of the invention, it will not be described in detail.
  • the essential organ of the mechanism is a ratchet clutch movable 15 having two coaxial toothed discs, lower 16 and greater 17.
  • the lower disk 16 meshes with the wheel of thirty-one 10 and thus turns in counterclockwise (hereinafter, SIAM).
  • SIAM counterclockwise
  • the upper disk 17 is trained in the SAM by a pusher 18 protruding from the middle of the box to form a button 19 accessible to the wearer of the watch.
  • a pressure on the button 19 advances the disc 17 one step, that is to say 360/31 °, then a spring 20 ensures the return of the pusher 18 to its initial position.
  • the mobile 15 is endowed, according to a construction well known to the man of craft, ratchets and a spring placed between the two disks 16 and 17, but not visible in the drawing.
  • the lower disk 16 turns thus in the SIAM regardless of the upper disk 17 which drives the disk 16 only when he turns in the SIAM, but not when he turns in the SAM, content, in this case, to charge the spring.
  • a first flip-flop 22, called a small flip-flop, is pivotally mounted around of an axis 23 on the upper face of the upper disk 17. It consists of two arms 22a and 22b, typically forming an angle of about 120 ° between them, and respectively directed towards the inside (22a) and towards the outside (22b) of the disc.
  • the outer arm 22b is normally held in abutment against a stop 24 disposed at the periphery of the disc 17 by a spring (not shown), while its end is flush with the edge of the disc. Note, as shown in Figure 2, that the small rocker 22 is at the same level as the finger 14 of the wheel of thirty-one 10.
  • the mechanism comprises a second flip-flop 25, called a big flip-flop, which pivots about an axis 26 riveted on the plate.
  • This rocker is roughly L-shaped.
  • Its small arm 25a is positioned at the level of the upper disk 17 and ends with a lug 27 that a jumper 30 applies against the teeth of the disc to prevent its rotation in the SIAM.
  • the big arm 25b of the large flip-flop 25 is disposed on the upper disk 17 and provided with a shoulder 28 arranged to receive the thrust of the small arm 22a of the small rocker 22.
  • the large arm 25b ends with a boss 29 intended for undergo the action of a safety pin 31 riveted to the upper face of the disc 17, when it rotates in the SAM.
  • the series of numbers 28, 29, 30, 31 is inscribed on a portion of the periphery of an indicator disk 32 attached to the disk shaft higher 17, above it.
  • a window 33 formed in the dial 13 shows, depending on the position of the disc 17, one of the numbers of the series.
  • the thirty-one wheel 10 rotates the disc lower 16 of the clutch mobile 15 in the SIAM, without this producing of effect, since the upper disk 17 is held stationary by the pin 27 and by the pressure of the jumper 30 on the small arm 25a of the large rocker 25.
  • the indicator disk 32 is then positioned so that the number 31 of the series of the disc 32 appears through the aperture 33.
  • the date display needle 12 normally performs its function and finger 14 goes over the disk higher 17 without his race crosses the small rocker 22.
  • the needle 12 skips the days 29, 30 and 31 and directly indicates the first March day.
  • the finger 14 comes into contact with the large arm 22b of the small rocker 22 and rotates about its axis 23.
  • the small arm 22a then comes push on the shoulder 28 of the large flip-flop 25, applying a pressure greater than that exerted by the jumper 30.
  • the big rocker 25 rotates and the lug 27 leaves contact with the toothing of the upper disk 17.
  • the upper disc 17 jumps three steps in the SIAM, moved by the spring that discharges suddenly. It drives together the disc lower 16 which meshes with the wheel of thirty-one 10. This one and the needle date indicator 12 therefore also jump three steps into the SAM.
  • the needle 12 then indicates the first day of the month on the series inscribed on the dial 13.
  • the number 31 of the series of indicator disc 32 appears from again through the counter 33.
  • the mechanism works from the way that has just been described, but the user applies respectively two or pressing the button 19 of the pusher 18 thus advancing the disc superior 17 of two or one step.
  • the security pin 31 is at the base of the boss 29 of the big arm 25b of the big rocker 25.
  • a new pressing the pusher 18 rotates the upper disk 17 by one step extra in the SAM and pad 31 pushes the boss 29 by applying a pressure higher than that exerted by the jumper 30.
  • the big rocker 25 rotates in turn and the lug 27 leaves the contact of the toothing of the upper disc 17, allowing the return of the spring of the mobile 15 to its rest position.
  • this invention finds a second application in a date mechanism perpetual, illustrated in Figure 4, which automatically takes into account the number of days of the different months.
  • the mechanism of Figure 4 is presented in a simplified version that does not not count leap years. It features a 40-month wheel divided into twelve sectors 41, each corresponding to one month of the year. Each of these sectors 41 is either toothless if it is identified at a month of thirty-one days, either with a tooth 42 for the months of thirty days, or equipped with three teeth 42 for the month of February. These teeth 42 are arranged in a manner that will be exposed later.
  • the teeth 42 are engaged with an intermediate mobile 43, meshing itself with the upper disk 17 of the clutch mobile 15.
  • the teeth of these different mobiles have identical steps, so that an advance of one not wheel 40 causes the same advance of the disk 17.
  • a star of the months 44 to twelve branches 45 is mounted coaxially and integrally in rotation of the wheel of 40 months.
  • Each branch 45 corresponds to a month of year.
  • the star 44 is positioned by a jumper 46 with two inclined planes, so that, for example, when the tooth 42a of the sector 41 has of the month April of the wheel 40 is engaged with the mobile 43, branch 45a of the month April is on the path of a finger 47 mounted on the shaft of a second wheel thirty-one 48.
  • the latter is identical to the first wheel of thirty-one 10 and meshes with her.
  • the length of the finger 47 is greater than the radius of the wheel 48.
  • the first thirty-one wheel turns in the SAM and coaches in the SIAM, on the one hand, the second wheel of thirty-one 48 and, on the other hand, the lower disc 16 of the clutch mobile 15 without other impact.
  • the finger 47 is arranged so as to be flush the branch 45b of the star of the months 44 corresponding to this month, preferably the first day of the month. Then, when, on that first day, around midnight, the wheel of thirty-one 10 and so the wheel 48 and the finger 47 advance one step, the latter pushes the branch 45b and drives the star 44 and the wheel of the 40 months of a step in the SAM. Already, they are in place for the following month.
  • the rotation of the wheel 40 and the star 44 is in two stages. First, the rotation is slow when the branch 45c resting on the jumper 46 raises it in sliding on its first inclined plane. Then the rotation is fast, when this branch arrives on the second inclined plane. The pressure then exerted by the jumper 46 accelerates the movement of the star.
  • Sector 41b of the wheel of the 40 months corresponding to a month of thirty-one days does not have teeth and thus does not drive the intermediate mobile 43, although it is located with respect to it during the rotation of the wheel.
  • the upper disc 17 of the clutch mobile 15 does not move either and no movement is transmitted to the wheel of thirty-one.
  • the disc indicator 32 shows, through the window 33, the number 31 corresponding to the number of days in the month.
  • the finger 47 comes flush with the branch 45a of the star 44 months corresponding to this month, also the first day of the month. Then, when, around midnight, the wheel of thirty-one 10 and thus the wheel 48 and the finger 47 advance one step, the latter pushes the branch 45a and drives the star 44 and the 40 month wheel in the SAM.
  • the teeth 42 of the wheel 40 months and, more particularly, the tooth 42a of the sector 41 a corresponding to this month of thirty days, are positioned way to drive the mobile 43 in the SIAM, at the time of the rapid phase rotation of the star 44.
  • the latter turns one step, in the SAM, the upper disk 17 of the clutch mobile 15, charging its spring but without causing the lower disk 16.
  • the small rocker 22 is now positioned so that its large arm 22b comes into contact with the finger 14 on the thirtieth day of the month, around midnight.
  • the number 30 on the disk indicator 32 appears through the window 33.
  • the large flip-flop 25 prevents any rotation of the upper disk 17 in the SAM.
  • the finger 14 advances by one step, it comes into contact with the large arm 22b of the small rocker 22 which pivots and pushes the large arm 25b of the large rocker 25. The latter turn in turn and releases the upper disc 17. It then jumps one step in the SIAM, moved by the spring of the clutch mobile 15 which discharges suddenly, and jointly drives the lower disc 16.
  • the thirty-second wheel and a 10 and the date indicator hand 12 also jump, too, one step, in the SAM.
  • the needle 12 indicates the 1st day of the month on the series written on the dial 13 and number 31 of the series of the disk 32 appears again through the window 33.
  • the mechanism works in the way just described, but the 40-month wheel does turn the intermediate mobile 43 and thus advance the upper disc 17 of three or two steps.
  • the month wheel makes it possible to display the current month by means of for example, an indicator needle mounted on its shaft and pivoting on a small dial.
  • a green area on the disk upper and occupying an angle of 360 ° / 31 can scroll under the dial. She is visible through holes corresponding to the positions occupied by this area green when the corrections were made for the months of 28, 29, 30 or 31 days.
  • the portions adjacent to the green zone are advantageously colored red to mean that the numbers in the 28, 29, 30, 31 series to which the red is assigned do not indicate the number of days in the current month.
  • a needle mounted in solidarity rotation on the upper disk shaft 17 indicates, on a portion of the dial, the number of days in the current month, based on the effective status of the corrector.
