Definitions

  • the present invention relates to a calendar watch comprising a movement making it possible to display at least the hour, the minute and the date by means of hands moving on a dial and rotating in the center of the movement, said movement comprising a plate carrying a mechanism comprising inter alia an hour wheel carrying in its center a first barrel on which the hour hand is fitted, and a song wheel located immediately under the dial and provided in its center with a second barrel rotating with play around said first barrel, the date hand being fitted onto said second barrel and said plate having a circular channel in its periphery.
  • the arrangement described uses a mechanism arranged entirely above the dial, which has the disadvantage of considerably increasing the thickness of the watch.
  • This same arrangement also uses an elastic blade secured to the barrel of the hour wheel which, every twelve hours, is raised by a cleat secured to the dial to bring the free end of said blade into engagement with the teeth of the wheel. edge, which advances by one step said edge wheel which is integral with the date indicator.
  • This mechanism requires a significant torque when the indicator is driven, which is unwelcome for watches driven by a stepping motor, itself controlled by a battery. On the other hand we can fear a jamming of the song wheel on the barrel of the hour wheel at the time of the advance of the indicator.
  • a date wheel having a central barrel on which a date hand is fitted is shown in document FR-A-1 031 926. This wheel does not, however, have any teeth. song so that it is centered and guided relative to the center of the movement by the barrel of the hour wheel, which is unfavorable as will be explained below.
  • a song wheel carrying a date hand is shown in GB-A-168 382. Apart from the fact that the teeth of this wheel are pins pegged on the wheel plate, the needle is not in the center of movement and the wheel which drives it is not guided by the teeth as in the present invention.
  • the calendar watch of the present invention is also constructed from a date window mechanism where the date ring is removed and is somehow replaced by the teeth of a song wheel.
  • the watch is characterized by the fact that the song wheel is provided with teeth integrally formed with the board that said song wheel has, said teeth being arranged to penetrate the circular channel and slide freely along the edge of small diameter that has said circular channel for centering and guiding said edge wheel relative to the center of the movement.
  • FIG. 1 shows a calendar watch 1 with hour 2 and minute hands 3 and a date hand 4 moving opposite date marks 5 affixed to a dial 6.
  • Indicators 2, 3 , 4 rotate in the center of a movement placed under the dial.
  • FIG. 2 shows the hour hand 2 and the minute hand 3.
  • a second hand, not shown, can complete the display system.
  • FIG. 2 also shows a date indicator or hand 4 rotating at the center of the movement and driven by a mechanism which will be described below.
  • the date indicator 4 is secured to a song wheel 9.
  • FIGS. 2 to 5 also show that the teeth 11 are integral with the plate 13 and this by simple folding, this constituting one of the characteristics of the invention.
  • the teeth 11 of the song wheel 9 is periodically driven by a finger 14 which moves in a plane which cuts the crown 12 in the direction of the height of this crown.
  • the finger 14 remains confined inside the cup formed by the face 13 and the crown 12 of the wheel 9.
  • the finger 14 is integral with a date driving wheel 15, which has an axis 16 which is parallel to the axis 17 of the song wheel 9.
  • a date driving wheel 15 which has an axis 16 which is parallel to the axis 17 of the song wheel 9.
  • the song wheel 9 has 31 teeth 11. If the drive wheel 15 makes one revolution in 24 hours, it will be understood that the date indicator will indicate the date or, in other cases terms, the serial number of each day in the month. However, the invention is not limited to indicating the date. It could be the days of the week, the month, the year, the phases of the moon or even the signs of the zodiac.
  • the calendar watch comprises a plate 20, which is only sketched in FIG. 2, this plate carries the mechanism of the watch and in particular the driving wheel 15 with its finger 14, and the hour wheel 7.
  • the hour wheel could directly drive the driving wheel.
  • a reference composed of two integral and coaxial gears, referenced 21 and 22, is interposed between the barrel wheel 7 and the date driving wheel 15.
  • FIGS. 4 and 5 are respectively a section and a plan view in a different location than that illustrated in FIG. 2, a figure which was mainly intended to explain how the song wheel was driven.
  • Figure 4 shows the channel 23 which was used to accommodate a date ring in a watch.
  • the channel is formed in the plate 20 and is covered by the dial 6.
  • this channel penetrates the toothing 11 of the song wheel 9 and the toothing 11 is freely adjusted on the edge 24 of small diameter presented by said channel. This adjustment allows the centering and guiding of the edge wheel relative to the center of the movement.
  • Figure 5 which is a plan view along arrow V of Figure 4 (the dial is removed) shows the circular shape of the channel 23 and how the inner edge of the teeth 11 rests on the edge 24 of said channel.
  • the hour wheel 7 is provided with a first barrel 25 on which the hour hand 2 is fitted.
  • the barrel 25 rotates freely on the roadway 8 which carries the 'minute hand 3.
  • the wheel 7 and the roadway 8 are coupled together by means of a conventional timer not shown.
  • the song wheel 9 is located immediately under the dial 6 and is equipped with a second barrel 10 raised in its center, and on which the date indicator 4 is driven.
  • the figure shows that a clearance 26 is formed between the first and second guns. This play makes it possible to avoid any jamming between said barrels, especially when the song wheel is driven.
  • This game is made possible thanks to the fact that it is the teeth of the song wheel which is used to center the wheel, as mentioned above.
  • Figures 2 to 5 show that the song wheel 9 has a plurality of tabs 27 which extend beyond the peripheral ring 12 presented by the toothing 11.
  • Figures 2, 4 and 5 also show a cover 28 which covers the periphery of the plate 20 extending partially on the circular channel 23 to the inner edge 29 of said cap.
  • the cover will preferably be shaped in such a way that it clamps on the plate by its rim 30.
  • the figures show that the cover 28 forms with the channel 23 an annular housing in which the tabs 27 of the song wheel move.
  • This construction makes it possible to fulfill several functions at the same time: the cover serves as a spacer between the plate and the dial, and the legs maintain the song wheel in height by preventing it from touching the dial. Finally, this arrangement makes it possible to offer a complete movement, even before the dial is placed, which facilitates handling.
