Definitions

  • This invention discloses a hands setting device in a watch mechanism, wherein the hands are settable by rotating a windproof glass which is airand water-tightly provided to the casing of the watch mechanism and selectively engageable with the driving shafts of the hands.
  • This invention relates to a hands setting device in a watch mechanism.
  • An object of the present invention is to provide a hands setting device according to an entirely novel invention made in view of disadvantages and defects as described hereinabove. According to the device of the present invention, its operation is extremely simple and ready, its
  • FIG. 1 is a cross sectional view showing a preferred embodiment of a hands driving device according to the present invention
  • FIG. 2 is a plan view of a gears disposition of the same.
  • FIG. 1 is cross sectional view showing a structure of an embodiment of the present invention, in which there are provided a Windproof glass 1 being made from a transparent material (e.g. plastics) and having a flange at the outer periphery thereof, a rotary plate 2 being also made from a transparent material (plastics) similar to that of the windproof glass 1, a hands driving gear 3 secured in contact with the central part on the back surface of the rotary plate 2, a knock-pin 4 being in engagement with said windproof glass 1 and the rotary plate 2 so that they are abutted to be rotated together, a spring-head 5 supporting the rotary plate 2 and having a round formed head, a coil spring 6, a column 7 for housing springs, a spring base plate 8, a face plate 9, a hub 10, a time-hand driving gear 11, a rear gear 12, a sleeve hub 13, a slip ring 14 of a minute-hand driving gear which is made from a spring "Ice board, a
  • the windproof glass 1, as the roulette part thereof is maintained pushed, is turned to either direction of rightwards or leftwards, the rotary plate 2 rotates in syncronism with rotation of the windproof glass 1, since said rotary plate 2 is engaged with the windproof glass 1 by means of the knock-pin 4, and torque of the rotary plate 2 is transmitted to the timehand gear 11 which moves in mesh with the hub 10, and resultantly the time-hand 24 is driven.
  • the rear gear 12 is driven, too.
  • Torque of said rear gear 12 is further transmitted to the sleeve hub 13 which is driven in mesh with said rear gear 12, and fixed in engagement with the minute-hand sleeve 21, and consequently the minute-hand becomes also driven
  • the minute-hand driving gear 15, however, is an idling pulley isolated from said minute-hand sleeve 21 and supported by the spring 14. Said minutehand driving gear 15 is normally in mesh with the third hub 16 during its rotation, and transmits the driving force thereof to the minute-hand sleeve 21 through the spring ring 14.
  • a contacting plate of a ring timer is tightly mounted on the surface of the hands driving gear and hands are drawn at a desired point on the surface of the rotary plate, it can be used as a timer.
  • hands of the timer can be readily moved to be set only by turning the windproof glass without pressure, in other word, by idling.
  • the watch mechanism according to the present invention provides a number of advantages.
  • a device as set forth in claim 1, wherein said means disposed in operating relationship with said glass comprises a plate, a gear member operatively engaged with 4 said plate and arranged to selectively engage said means for rotating said hands, and means for normally biasing said plate and gear member into a disengaged position relative to said means for rotating said hands.
  • a device as set forth in claim 2, wherein said means for biasing said plate comprises at least one spring assembly mounted within said housing.
  • said means for rotating said hands comprises a hub member positioned within said housing, an hour hand gear positioned on said hub, and said gear member operatively engageable with said plate selectively engageable with said hub by depressing said glass and plate against the biasing action of said spring assembly.
