Definitions

  • the present invention relates to date mechanisms for watches, of the type in which the date display device advances one step per day, except the last days of the months that count less than thirty-one.
  • the document CH 680 630 describes a perpetual mechanism which includes a date wheel comprising, in superposition, three wheels having teeth prominent in variable number, defining how many jumps the indicator date should perform. It is thus possible to remove the cams and the necklaces, but the volume occupied is important.
  • the main object of the present invention is to propose a mechanism simple and energy efficient, allowing automatic correction at least at the end of the thirty-day months.
  • this mechanism is characterized in that it comprises, in in addition, a third kinematic link, connecting the date wheel to the month indicator, at the end of months less than thirty-one days, after that the second kinematic link ensured the training of a step of the month indicator, to ensure training of at least one step additional month indicator and by the second link kinematics, of the date indicator.
  • the month indicator is divided into equal sectors on the basis of one sector for the months of thirty-one days and two sectors for months less than thirty-one days and has a wheel which includes as many teeth as the indicator has sectors, this wheel being connected to the date wheel by the third kinematic link, and to the date indicator by the second kinematic link.
  • the third kinematic link includes a finger secured to the date wheel and a cam secured to the indicator month which includes lugs cooperating with this finger, so that the latter involves an additional step, at the end of each months of less than thirty-one days, the month indicator and, for via the second kinematic link, the date indicator, after that the date wheel blew up the date indicator by a first step and, via the second kinematic link, the month indicator.
  • the second kinematic link thus thus links the date indicator to the month indicator when going from the thirty-one to the first for the months thirty-one days and when switching from thirty to thirty-one for the months less than thirty-one days. For months less than thirty-one days, this second link links the month indicator to the date indicator for change the date display from thirty-one to first.
  • This second link advantageously includes first and second teeth, which are arranged on the date indicator, one of a first type, the other of a second type, and a month return with a toothing formed by teeth of a third and fourth type, cooperating with the two teeth of the date indicator and in engagement with the the month indicator, the month indicator wheel and the reference with the same number of teeth.
  • the teeth of the first, second, third and fourth types are arranged so that the first tooth type results in teeth of the third type only, while the tooth of second type trains both third and fourth teeth type when the second link connects the date indicator to the indicator of month.
  • the month indicator is divided into equal sectors on the basis of one sector for the months of thirty-one days, two sectors for the thirty-day months and four sectors for the February.
  • This indicator has a wheel that includes as many teeth that the indicator has sectors and which is connected to the wheel date by the third kinematic link, and to the date indicator by the second kinematic link.
  • the third kinematic link includes a sector toothed secured to the date wheel and a cam secured to the indicator months and including pins arranged so that they cooperate with this sector so that it leads to the month indicator one step after the date indicator has jumped from thirty to thirty-one when the month displayed has thirty days, and three steps in February, after that the date indicator jumped from twenty-eight to twenty-nine.
  • the movement comprises a plate 10 on which are mounted its other components.
  • This plate is provided, in the center of its upper face, of a tube 12 on which a minute mobile 14, formed a roadway 14a and a wheel 14b, is mounted to rotate freely.
  • a wheel at cannon 16 is mounted on the roadway 14a and rotated, at a rate of a turn in twelve hours, by the mobile of 14 minutes, via of a timer mobile not shown in the drawing.
  • the date driving wheel 18 is formed by a hub 25, a board 26 with peripheral teeth and two elastic fingers 28 and 30, arranged respectively on the upper and lower faces of the plate 26 and secured, by their rigid end, to the hub 25.
  • the function of these fingers will be specified below.
  • the date indicator 20 is formed by two coaxial rings and superimposed 32 and 34.
  • the upper ring 32 carries the numbers of date and, on the inner edge, two teeth 36 and 37 sweeping the space occupied by the toothing of the reference 24, the tooth 37, of a first type, being more thinner than tooth 36 of a second type.
  • the lower ring 34 includes thirty-one teeth 38 distributed evenly over its inner edge and intended to cooperate with the finger 30 of the wheel 18.
  • the two rings are connected to each other by pillars 39, thus defining an annular space 40 open on the outer edge of indicator 20.
  • the 22 month indicator includes, coaxial overlays and assembled rigidly to each other, by means of screws, a board 44 provided with five pins 46 arranged radially and intersecting the path traveled by the finger 28, a star wheel 48 comprising seventeen teeth, in engagement with the reference 24, and a disc 50 whose upper face is divided into seventeen equal sectors, each sector having a month indication, those of thirty and one day appearing once and those less than thirty-one days twice of following, seventeen indications.
  • the reference 24 has seven teeth 52, of a third type, which are thinned, and ten teeth 54, of a fourth type, extending over its entire thickness. This reference 24 cooperates with the date indicator 20 and, more particularly with teeth 36 and 37. More specifically, thin teeth 52 are arranged so as to be driven by the tooth 36 only, the tooth 37 passing below them, while thick teeth 54 are indifferently driven by teeth 36 and 37.
  • the date mechanism also includes jumpers which do not have are shown in the drawing, in order to avoid overloading it, and which are intended to ensure, in a manner well known to those skilled in the art, the positioning date and month indicators, as well as reference 24.
  • the date indicator 20 is rotated by the elastic finger 30, which cooperates with one teeth 38 of ring 34.
  • Reference 24 is arranged and arranged so that, at the end of the months thirty-one days a thin tooth 52 is in the space swept by the teeth 36 and 37. When changing from thirty to thirty-one of the month, the tooth thin 37 goes below the thin tooth 52. So there is no interaction. At the end of the next day, the thick tooth 36 comes to rest against the thin tooth 52 and advances the reference 24 by one step, and, with it, the month indicator 22.
  • a thick tooth 54 which is in the space swept by teeth 36 and 37.
  • the thin tooth 37 drives the thick tooth 54, which makes turn the reference 24 and the month indicator 22.
  • Plate 44 of the latter is then arranged so that a lug 46 is in the space swept by finger 28. This finger 28 comes to rest within an hour against one of the lugs 46, which makes the month indicator jump one step additional and causes the reference 24 and the date indicator 20 by engagement of a thick tooth 54 with the thick tooth 36.
  • the indicators of date and months make two successive jumps when changing of month, the date indicator thus passing from the thirty to the first.
  • These two jumps are controlled by the driving wheel 18, the first by a first kinematic link formed by finger 30 and teeth 38, ensuring the training of the date indicator 20, and the month indicator 22 by a second kinematic link formed by tooth 37, reference 24 and star 48.
  • the second jump is controlled by a third kinematic link formed by finger 28 and board 44 by its lugs 46, ensuring driving the indicator for months 22 and the second kinematic link, but in the opposite direction to the first jump, the star 48 causing the return 24 which blows up the date indicator 20 via tooth 36.
  • the mechanism as described only requires correction at the end of the month from February.
  • the date indicator 22 includes nineteen sectors, one for the months of thirty-one days, two for the months of thirty and four days for February, the star wheel 48 and the return wheel 24 comprising as many teeth.
  • the elastic finger 28 is replaced by a toothed sector comprising three teeth, intended to cooperate with a lug 46 to the end of the thirty-day months and three lugs 46 to ensure the jump of the twenty-nine to thirty, from thirty to thirty-one and from thirty-one to the first at the end of February.
  • the date indicator 20 includes two additional teeth arranged upstream of teeth 36 and 37 and differing from these, so that they only cooperate with the reference 24 at the end of February.
