Definitions

  • Conventional day calendar display mechanism represents a series of days expressed only with a sole language, for instance, English, French, German, Spanish, Japanese or the like.
  • the object of the invention resides in the provision of an improved day calendar display mechanism bearing several series of calendar displays expressed in several languages and any one of these different language displays can be brought into its practical usage at the will of the timepiece wearer.
  • FIG. 1 is a plan view of a first embodiment of the invention.
  • FIG. 2 is a section of the mechanism shown in FIG. 1, the section being taken substantially along a section line I-I' shown therein.
  • FIG. 3 is a similar view to FIG. 1, illustrating a second embodiment of the invention.
  • numeral represents a conventional day feed gear which is rotatably mounted on a conventional plate 26 of a timepiece movement, not specifically shown, and arranged as conventionally to perform a complete revolution for 24 hours by being reducingly driven from a conventional houror cannon wheel, not shown.
  • a single pin 11 is fixedly mounted on the gear wheel 10.
  • Numerals lla 11c represent successive positions of this pin 11.
  • Numeral 12 represents a conventional day dial driving wheel which is rotatably mounted on the plate 26 and engages with a day star wheel 13 having seven star projections or teeth 13a-13g which is rotatably mounted on a conventional hour or cannon wheel.
  • Numeral 22 represents only a part of a conventional day dial bearing thereon a alternately combined series of day calendar displays expressed in Japanese and English and fixedly attached to the day star wheel 13, although the attaching means has been omitted for its very popularity and for simplification of the drawing.
  • the pin is so designed and arranged that it may engage with the teeth, being represented only by a single and common numeral 12a, the wheel 12 being fed two tooth pitches for a complete revolution of the wheel 11.
  • a jumper lever 15 is fixedly mounted at its root end 15a by means of two fixing screws 15b on the plate 26 and designed and arranged to cooperate with the star wheel 13, as conventionally.
  • This jumper lever 15 is, however, fonned at its free end with a pair of substantially triangular engageable projections 15c and 15d, a lateral recess or groove lSe being formed therebetween.
  • the circular pitch of these projections 15c and 1511 is one half the pitch of the star wheel teeth 13a13.
  • Each step of the successive engagements of the jumper lever with the star wheel is thus performed by a half of the tooth pitch of the star wheel.
  • Day correction lever 16 is pivotably mounted at 18 on the plate 26, the tip end 17 of the lever engaging with the teeth of wheel 12 and the opposite or root end 19 being kept in pressure contact with an operating button 21 which is arranged slidable in the radial direction of the plate 26.
  • an operating button 21 which is arranged slidable in the radial direction of the plate 26.
  • a leaf spring 20 acting as a return spring for the lever 16. By the provision of this return spring, the lever 16 is urged resiliently to turn in counter clock-wise direction in FIG. 1.
  • Numeral 24 represents imaginally the position of a conventional display window formed in the conventional dial plate, not shown, of the timepiece movement for allowing to see the occasionally displayed day display therethrough by the timepiece wearer.
  • the display corresponds to Getsu which is an abbreviation of Getsuyo" corresponding to Monday in English.
  • the pin 11 on the day feed gear 10 will shift from 11a through 11b to 110, thus the day dial drive gear 12 being advanced two teeth, as was referred to hereinabove.
  • the day star wheel 13 will be advanced just one pitch.
  • the wheel 12 is formed with 14 teeth.
  • FIG. 3 the second embodiment of the invention will be described.
  • all the same or similar constituents have been represented by the respective same reference numerals as before, irrespective of minor configurational and functional differences.
  • the operating button 21 has been dispensed with.
  • the desired calendar display conversion is carried into effect by such operation that the day feed wheel is turned in a reciprocating manner so as to shift the pin 11 from 11a to 11c and then back to 11a.
  • the relative arrangement of said pin 1 1 to the drive wheel 12 is as before so that the latter is fed two teeth for a complete revolution of the gear 10.
  • the timepiece wearer manipulates the conventional winding stem, not shown, to advance the gear 10 so as to advance in clockwise direction in FIG. 3 the pin 1 1 from the position 11a to a new one 1 1b, thus the star wheel 13 being rotated just a half tooth pitch thereof.
  • the Japanese calendar is replaced by the English calendar.
  • the timepiece wearer manipulates the winding stem in the reverse direction, so as to rotate the gear 10 in counter clockwise direction in FIG. 3 from the positiori 11b to that shown at 110.
  • the star wheel 13 may be rotated in counter clockwise direction in a corresponding way, when the tooth backlash on the wheel 12 has been selected more loosely than the conventional value and the slopes on the projections 15a and 15b on jumper lever 15 have been selected more gentle than before, the desired operation can be attained without inviting a disorder engagement of the jumper projections.
  • the pin 11 is returned to the position 11a. Thence, the day calendar displays will be viewable through the window 24 and in English in place of Japanese version, as the timepiece operates as usual.
  • n is equal to 3.
  • the timepiece manufacturer can manufacture a large number of a unified style of the star wheel-and-calendar dial-combination. Only necessary procedure to be taken at the side of the manufacturer is to ⁇ print differently selected calendar representations wit conveniently adopted several languages familiar to the timepiece consumers.-
  • a display mechanism of a day calendar timepiece comprising a day feed gear, a day dial driving wheel, and a day star wheel mechanically connected one after another, a jumper lever resiliently cooperating with said star wheel and a day calendar dial fixedly mounted on said star wheel, said star wheel being formed on its periphery with seven teeth, the improvements comprising n different day calendar representations, n being preferably the number of different languages employed, and n successive jumper projections formed on said jumper lever for cooperation with said star wheel for positioning said star wheel at n different positions for each of 7 day calendar displays.
