  • FIG. 3(b) is a block diagram similar to FIG. 1(b) and corresponding to FIG. 3(a);
  • FIG. 4 is a sectional view taken along the line IV-IV' of FIG. 1(a).
  • a stem 1 is formed with a groove for the insertion of a setting lever axle 6a.
  • a date correcting wheel 3 is loosely mounted on a columnar portion of the stem 1 and a crown 2 is fixed to one or outer end of the winding arbor 1 by means of a screw, while a clutch wheel 4 is loosely mounted on a quardrangular portion at the other end of the stem 1.
  • the arrangement is such that, when the crown is pushed or pulled, a clutch lever 5 having one end 5a engaged in an annular groove 40 of the clutch wheel 4 is operated by a clutch pushing pin 6b of the setting lever 6, whereby the clutch wheel 4 on the quadrangular portion of the stem 1 is shifted.
  • the clutch wheel 4 is rotatably supportedby a pin 14 pro vided on a lower plate 20.
  • the clutch lever 5 has an end portion 5a for engagement with the annular groove 4a of the clutch wheel 4, an elastic portion 5b and three stepped portions 5c for engagement with the clutch pushing pin 6b of the setting lever 6.
  • the stepped portions determine the positions of the setting lever 6 and the stem 1 to engage said setting lever 6, and control the position of the end portion 5a of the clutch lever 5 to determine the position of the clutch wheel 4 to engage the date correcting wheel 3 or a setting wheel 7.
  • the clutch wheel 4 and the date correcting wheel 3 are intermeshing each other through ratchet teeth 4b and 3a thereof.
  • a rocking bar wheel 8 is rotatably mounted on a rocking bar 9 and held in meshing engagement with the setting wheel 7.
  • the setting wheel 7 and the rocking bar 9 are rotatably mounted on the lower plate 20 by a screw 23.
  • One end of the rocking bar 9 is provided with a projecting pin 9a which is engaged in a curved slot of the setting lever 6.
  • An alarm setting correcting wheel 10 is arranged such that its alarm setting correcting gear 10a will engage an alarm wheel 11 and its-alarm setting correcting pinion 10b with the rocking bar wheel 8 when the alarm setting is to be corrected.
  • a minute wheel and pinion 12 is meshing with a cannon wheel 13, etc.
  • a terminal 15 of a watch driving circuit and a terminal 16 of a buzzer circuit respectively consist of elastic members made of an electrically conductive material and are fixed to the lower plate 20 by means of screws 17, 59 but electrically insulated therefrom.
  • One ends 15a, 16a of these terminals are provided with contacts 15b, 16b respectively which are made of an electrically insulating material and engaged by a switch pin 6d of the setting lever, whereby the contact between an earth terminal 19 projecting upright from the lower plate and the terminal 15 of the watch driving circuit or the terminal 16 of the buzzer circuit or, in other words, switching is controlled.
  • Reference numeral 22 in the I block diagrams of FIGS. 1(b), 2(b) and 3(b) designate an alarm switch of the buzzer circuit.
  • the winding arbor has three stable positions.
  • the stem In FIG. 1(a), the stem is in the most pushed-in position, and the wrist watch is carried, normally with the stem in this position.
  • the crown when turned in the direction of the arrow, rotates the clutch wheel 4 which in turn rotates the date correcting wheel 3 meshing therewith, whereby a date is corrected.
  • the terminal 15a of the watch driving circuit and the terminal 16a of the buzzer circuit are both in contact with the earth terminal 19, maintaining the watch in operation and the buzzer in a state ready to sound an alarm as soon as the alarm switch 22 is turned on.
  • the terminal 16a of the buzzer circuit is out of contact with the earth terminal 19, so that the buzzer will not be actuated even if the alarm setting switch 22 is turned on.
  • the rocking bar 9 is turned in the clockwise direction by the curved slot 60 of the setting lever 6, while the projecting pin 9a of the rocking bar 9 is held in engagement with said curved slot 6c, and the rocking bar wheel 8 pivoted on the rocking bar 9 is set in a position to engage the minute wheel and pinion 12.
  • Time setting can be achieved by turning the crown 2 in this state.
  • the terminal 15a of the watch driving circuit and the terminal 16a of the buzzer circuit are both out of contact with the earth terminal 19, so that the watch is held inoperative and the buzzer will not be actuated even if the alarm setting 7 switch is turned on.
  • the buzzer switch is turned on and the buzzer is actuated at the preset time, with the stem or crown being in the most push-in position. It is generally preferable that the stem be in its most push-in position during using the watch, for such reasons that it is easy to carry the watch, that inadvertent push-in of the stem can be avoided, and that the stem position is not subjected to the influence of movement of the arm on which the watch is worn.
  • the buzzer when the buzzer is actuated at the preset time, the alarm sound can be stopped by pulling out the stem one step and, when the operation of the buzzer is not desired, the buzzer can be held inoperative even if the preset alarm time has come, by holding the stem in the position one step out of the most push-in position.
  • the buzzer is not actuated even when the preset time has come during the time setting operation.
  • Arranging the watch such that the buzzer is actuated in the time setting position is advantageous in that it is easy to match a preset alarm time and an indicated time in the process of assembly and in that the actuation of the buzzer can be confirmed beforehand by the time setting operation.
  • Various combinations of the stem position and stem operation are possible by varying the cam shapes of the contacts 15b, 16b of the terminals l5, 16 or by varying the shape of the setting lever 6. An example of different combination is shown in the table given below:
  • the watch switch and buzzer switch can be operated by the stem only. Therefore, additional operating members are not required which would otherwise be necessary. Accordingly, extra holes need not be bored through the watch casing. This facilitates the manufacture of the watch casing and, in case of the watch casing being water-proof, eliminates water-proof means other than that for the stem passage hole, which would otherwise be required for such extra holes.
  • the wrist watch according to the invention therefore, is the same as the ordinary one in respect of water-proofness and appearance.
  • the watch In the event when it is unnecessary to actuate the buzzer, the watch is not placed in out of order by inadvertent rotation of the stem, because the stem has, in addition to the time setting position, another stable position in which the buzzer switch is held in the off position. Further, it is easy to stop the alarm at an intermediate point of the alarm sounding period, without imposing any adverse affect on the watch operation.
  • the present invention has excellent advantages.
  • a correction switching device for a wrist watch provided with an electronic buzzer, comprising a. a stern having at least three stable positions,
  • an electronic buzzer switch to determine whether current is given to said buzzer operated by said stem to be set in the of position when said stem is in the alarm setting position and in the on position when said stem is in the stable position other than the time setting position and the alarm setting position.
