  • the alarm time set ring includes a downwardly extending outer portion comprising a ring gear which is engage- 3596460 8/1971 z fi l a 58/57 5 X 1 able by the stem pinion to set the alarm. 3,611,702 10 1971 8 Claims, 5 Drawing Figures ELECTRIC ALARM TIMEPIECE BACKGROUND OF THE INVENTION for example, a ring or separate contact element which may be rotated to set the desired alarm time. After setting, this latter contact remains stationary and is contacted by the moving contact means to activate the alarm mechanism.
  • the alarm set contact has indicator means coupled thereto so that the time setting can be seen visually by the wearer.
  • switch reliability One of the problems encountered in alarm watches is switch reliability.
  • the switch must be as inexpensive, small and durable as possible and yet must possess the necessary reliability. After continued use, the contact spacing may tend to increase so that proper engagement of the contactsdoes not occur. This may cause intermittent ringing or the alarm may fail to ring at all.
  • Pat. No. 3,638,418 issued Feb. 1, 1972 'which is directed specifically to the switch arrangement for an electric timepiece.
  • TheSpadini patents disclose, in general, an arrangement wherein switch contact is made between an axial extension coupled to the hour hand and an axial extension coupled to the alarm hand This differs considerably from the structure of the present invention as does U.S. Pat. No. 3,596,460 to Wuthrich which issued Aug. 3,1971 and which discloses an alarm set disc carrying a contact point for making electrical contact with contact means mounted on the hour wheel.
  • the present invention relates to an electric alarm watch having an on-off switch wherein contact closure is produced by surface contact between the bottom surcomprising a ring gear which is engageable by the stem pinion to set the alarm.
  • the object of this invention is to provide a new and improved electric alarm timepiece.
  • a more specific object of this invention is to provide a new and improved electric alarm watch including a switch arrangement having numerous advantages over conventional alarm watch switches.
  • FIG. 1 is a top plan view of the face of an alarm watch incorporating the switch arrangement of the present invention
  • FIG. 2 is an enlarged partial view of the watch as shown in FIG. 1 with portions shown in cross-section;
  • the invention comprises an electric alarm watch 10 which includes an improved alarm on-off switch 11 which will be described in greater detail hereinafter.
  • the watch 10 may be a day-date type watch although the invention may be incorporated in other type watches.
  • the watch movement (not shown) including alarm switch 11 is. mounted in watch case 12 between the crystal l3 and watch back 14.
  • the alarm circuit and alarm or buzzer are not discosed in detail since they are conventional. and any number of different arrangements may be used.
  • the subject alarm watch 10 of the preferred embodiment includes an hour hand 16, a minute hand 17, and a second hand 18 and in addition an alarm set indicator means 19.
  • a day ring 21 and a date ring 22 are visible through windows 23 and 24 respectively in the dial 26.
  • Conventional indicia 27 are mounted about the watch 10 to indicate time in cooperation with the hands 16, 17 and 18.
  • An alarm set ring 28 of transparent material is mounted beneath the indicia and extends circumferentially. about the watch.
  • the ring 28 which may be of plastic material includes inner and outer concentric rings 29 and 31 which comprise knurled surface portions on the upper surface of the alarm'set ring 28. These knurled portions provide a pleasing esthetic effect and obscure visibility into the watch;
  • the inner. ring 29 obscures the contact between the hour hand 16 and the alarm set spring 19 which comprises the alarm set indicator means.
  • the present invention is designed to provide positive contact between the contact portion 32 of the alarm set spring 19 and the tip 33 of the hour hand 16 at a predetermined alarm time.
  • the alarm circuit is activated.
  • the contact portion 32 of alarm set spring 19 is slightly offset and raised so that contact is established when the main portion of the spring 19 and the hour hand 16 are aligned. This offset portion 32 is hidden by the knurled ring 29.
  • the positive switch contact is provided by a formed ridge 34 on the alarm set ring 28 which guides the tip 33 of the hour hand 16 into engagement with the alarm set spring 19.
  • the ridge 34 is an extension of the'upper surface of the ring 28 and forms a recess 36 with the main body of the ring 28.
  • the tip 33 of the hour hand 16 rotates within the recess 36 while the set spring 19 is located beneath the hour hand 16.
  • the spring 19 is mounted to ring member 28 at 37 and is cantilevered outwardly therefrom towards the interior of the watch 10. Positive switch contact is thus provided by this arrangement over long periods of use thereby insuring a high degree of reliability in the alarm arrangement.
  • the alarm set ring 28 includes a curved body portion 38 leading to the ridge portion 34 extending inwardly at the inner periphery of said ring28.
  • the outer periphery of the ring 28 includes a downwardly'projecting portion 39 including ring gear means 41 at its lower extremity.
  • the ring 28 is rotated about the watch to set the alarm time by means of the ring gear 41 which is engaged by gear means coupled to the stem 42.
  • the alarm time is set by means of the conventional stem arrangement shown in the drawings.
  • the stem 42 includes an elongated shaft 43 which extends into the main body of the watch 10 and is held in position by mounting means 44 of member 45.
  • The'shaft 43 includes a pinion 46 mounted on an intermediate portion thereof and enlarged portion 47 which acts as a switch actuating means. Located inwardly of enlarged portion 47 are contoured shaft portions 48 and 49 which are engaged by member 51 to lock the stem in various positions within the watch.
  • the stem pinion 46 is designed to engage the ring gear 41 thereby rotating the alarm set spring 19 to a predetermined alarm time.
  • the pinion 46 and ring gear 41 are shown in engagement in FIGS. 2 and 3. This curs when the stem 42 is pulled, outwardly fromthe watch for alarm setting purposes. At this time, en-
  • the alarm set ring 28 may be rotated by means of the stem 42, causing the alarm set spring 19 which is mounted thereto to be moved to the desired alarm time.
  • the stem 42 is then disengaged from the ring 28.
  • the tip 33 of the hour hand 16 guided by ridge 34 engages the contact portion 32 of the alarm set spring 19, completing the alarm circuit to a conventional buzzer arrangement.
