Description

[Detailed description of the invention] The present invention relates to a snooze indicator mechanism.

Conventionally, when this alarm mechanism with a snooze (mechanism that can temporarily stop the alarm) is incorporated into an alarm clock, for example, a ratchet gear is arranged in parallel with the gear that meshes with the hour wheel, and when the snooze button is pressed, the A lever operated by the snooze button is configured to mesh with the ratchet gear, and as time passes, the gear having the ratchet gear is rotated by the clock wheel, and the engagement between the lever and the ratchet gear is disengaged. Furthermore, the switch is opened and closed as appropriate by the operation of the lever,
It is provided to perform a snooze operation. However, the above configuration requires a gear with a ratchet gear for the snooze mechanism in addition to the normal gear mechanism, which has drawbacks such as an increased number of parts and complicated assembly. . The present invention eliminates the above-mentioned drawbacks, and provides a snooze indicator mechanism that reduces the number of parts and improves ease of assembly, and an alarm clock having the mechanism.

Further, the push-up spring 18 is provided so as to be able to come into contact with the fixed contact 26 projected into the mechanism chamber 9 when the interlocking pawl 17 of the hour hand wheel 15, which is pressed by the push-up spring 18, engages with the pawl engagement hole 14. It is being A push button 27 that acts on the other end of the push-up spring 18 is projected inward from a hole 28 in the side wall of the mechanism chamber 9, and a split engagement portion 29 at the tip is engaged in the engagement hole 8 of the vertical piece 7. and has a recess 30, one wall surface 31 of which
is provided to push up the tongue portion 25 of the extension portion 24 of the push-up spring 18 and to ride the extension portion 24 on the push button 27. Further, the split engagement portion 29 of the recess 30 is connected to a snooze cam 32 pivotally supported on the support shaft 6.
The extension part 33 of the snooze cam 32 is provided so as to be pushed forward, and on the other hand, a sickle-shaped locking part 34 extends on the opposite side of the snooze cam 32 from the extension part 33, and the extension part 33 and the locking part 34 A tongue piece 35 is provided which extends in a direction perpendicular to the push-up spring 18, and the tongue piece 35 is formed so that the tongue piece 23 of the push-up spring 18 is mounted thereon. Additionally, the snooze cam 32 is spring loaded to urge its extension 33 toward the push button 27.

The minute hand wheel 36 is pivotally supported by a minute hand pipe 37, and the minute hand pipe 37 and the minute hand wheel 36 are slip-coupled. Further, the minute hand pipe 37 penetrates into the hollow shaft cylinder 16 of the hour hand wheel 15 with the push-up spring 18 interposed.
A ratchet gear 38 and a pinion 39 are provided which protrude and are lockable with the locking portion 34 of the snooze cam 32. Further, the minute hand wheel 36 is meshed and connected to the second hand wheel 41 via a transmission wheel 40, and the second hand 42 fixed to the second hand wheel 41 penetrates through the main plate 61 and into the minute hand pipe 37 of the minute hand wheel 36. It is prominent. Said second hand wheel 4
1 is connected to the fourth wheel & pinion 44 and the third wheel & pinion 4 via the circuit board 43.
5. Rotor 48 via second wheel 46 and first wheel 47
It is linked to the output shaft 49 of. The rotor 48
is provided to be driven by a coil 51 connected to a battery in the power supply room 10 via a circuit block 50 attached to the circuit board 43. That is, as is well known, the operation of the circuit block 50 causes the coil 51 to
A current is periodically passed through the coil 51, a magnetic field is generated around the coil 51, and the rotor 48 is driven to rotate.

A transmission wheel 52 that engages with the indicator wheel 11 is rotatably mounted on the boss 4 and is prevented from coming off by a stop pin 53, and a minute wheel 54 that engages with the pinion 39 of the minute wheel 36 is attached to the vertical pin 5. It is pivoted. Further, the pinion 55 of the minute wheel 54 is meshed and connected to the hour wheel 15. A cover 5 is pivotally supported by a pin 56 in the mechanism chamber 9 and is attached to the case 1.
A needle rotating shaft 58 protruding from the needle rotating shaft 7 is applied with the spring force of a spring 59, and its gear 60 is meshed and connected to the transmission wheel 52.

Furthermore, the operation of the alarm clock to which the present invention is applied will be explained in detail. If we apply the voltage of the battery in the power supply room 10 now,
Second hand wheel 4 via coil 51 and reduction gear
1. The minute hand wheel 36 and the hour hand wheel 15 are driven, and the clock mechanism operates. Further, by rotating the needle rotating shaft 58, the indicator wheel 11 is rotated via the gear 60 and the transmission wheel 52, and the indicator wheel 11 can be set at an appropriate time. When the set time is reached and the interlocking pawl 17 of the hour hand wheel 15 engages in the pawl engaging hole 14 of the indicator wheel 11,
The push-up spring 1 is in contact with the reference wheel 11 and the hour hand wheel 15.
8 comes into contact with the fixed contact 26, and a buzzer mechanism (not shown) connected between the push-up spring 18 and the fixed contact 26 sounds.

On the other hand, as shown in FIGS. 3 to 5, when the push-up spring 18 contacts the fixed contact 26 and the alarm buzzer is sounding, the buzzer sound is temporarily stopped.
That is, when performing a snooze operation, if the push button 27 is pushed against the spring force as shown in FIGS. 6 to 8, the push-up spring 1 is
The inclined tongue part 25 of the extension part 24 provided at the other end of 8 is pushed up. Furthermore, the extension part 33 of the snooze cam 32 is pressed by the wall surface 31, and the snooze cam 3
2 is rotated, and the locking part 34 is moved so as to mesh with the ratchet gear 38 of the minute hand wheel 36. At the same time, the tongue piece 23 at the other end of the push-up spring 18 is mounted on the tongue piece 35, and the tongue piece 23 at the other end of the push-up spring 18 is mounted on the tongue piece 35, and the locking part 34 is moved to mesh with the ratchet gear 38 of the minute hand wheel 36. The push-up spring 18 opens and the circuit of the buzzer mechanism is interrupted. In addition, when the locking portion 34 of the snooze cam 32 is driven by the ratchet gear 38 after a certain period of time has elapsed, the push button 27 is moved back by the spring force applied to the snooze cam 32, and is pushed up from the tongue 35 of the snooze cam 32. As the tongue piece 23 of the spring 18 comes off, the push-up spring 1
The extension 24 of 8 is recessed into the recess 30 of the push button 27, and the push-up spring 18 comes into contact with the fixed contact 26 again, causing the buzzer to sound.

As shown in FIG. 9, when the snooze cam 32 returns, while the locking portion 34 of the snooze cam 32 is locked to the ratchet gear 38 of the minute hand pipe,
If the size θ of the tongue piece 35 in the rotational direction is selected so that the tongue piece 23 of the push-up spring 18 and the tongue piece 35 of the snooze cam 32 are separated, the locking part 34 can be attached to the ratchet gear 38 by, for example, one tooth. Even if they are misaligned, the temporary stop time of the buzzer will not change.

According to the snooze indicator mechanism of the present invention configured as described above, the ratchet gear that forms part of the snooze mechanism is incorporated into the minute hand pipe, eliminating the need for a gear with a separate ratchet gear and reducing the number of parts. This achieves effects such as reduction in size, ease of assembly, and so on.
