Description

[Detailed description of the invention] The present invention relates to an alarm clock with a snooze mechanism.

Conventionally, this type of alarm clock with a snooze mechanism has a flashing mechanism for a lighting lamp that is separate from the buzzer linked to the snooze mechanism, so for example, when the buzzer sounds, the alarm clock can be stopped once. In order to turn on the illumination lamp, a separate operation must be performed, making the structure complicated and the operation extremely complicated.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide an alarm clock with a snooze mechanism that is simple in structure and easy to use.

An alarm clock with a snooze mechanism according to the present invention will be explained below along with the drawings.

The conductive push-up spring 18 is mounted on the base 1 provided at the corner of the mechanism chamber 9.
9 through a pin 20, and a dowel 2 approximately in the center.
A ring portion 21 having a dowel 2 is formed, and the dowel 2
2, the hour hand wheel 15 is pressed into contact with the hour hand wheel 15.

An extension part is formed at the other end of the push-up spring 18, and the extension part 23 has tongue pieces 24, 2 that are inclined on both sides in a direction perpendicular to the extension direction of the push-up spring 18 and extend in different directions.
5 is provided, and the free end 26 forms a contact part.

Further, when the interlocking pawl 17 of the hour wheel 15, which is pressed by the pressing spring 18, engages with the pawl body hole 14, the push-up spring 18 is inserted inward from the hole 27° 28 in the side wall of the mechanism chamber 9. It is provided so as to be able to come into contact with the contact terminal plates 29 and 30.

An operation button 31 that acts on the other end of the push-up spring 18 projects inward from a hole 32 in the side wall of the mechanism chamber 9, has a tip inserted into the guide hole 8 of the vertical piece 7, and has a recess 33. The extension portion 23 of the push-up spring 18 is inserted through one wall surface 34 thereof.
The tongue pieces 24 and 25 are also mounted on the tongue pieces 24 and 25.

Further, a rack portion 37 is provided at the tip of the operation button 31 and engages with a pinion portion 36 of a snooze pawl 35 pivotally supported on the support shaft 6. On the other hand, the snooze pawl 35 has a hook-shaped locking portion. 38 has been extended.

Furthermore, a spring load is applied to the snooze pawl 35 so as to push the operation button 31 having the rack part 37 that engages with the pinion part 36 to the outside of the mechanism chamber 9.

The minute wheel 39 has a hollow shaft cylinder 40 connected to a hollow shaft cylinder 40 of a main plate 41.
2 is penetrated and held on the main plate 41, and the hollow shaft tube 40 is penetrated and protruded by the hollow shaft tube 16 of the hour hand wheel 15 through the push-up spring 18, and the snooze pawl 35 is engaged with the hollow shaft tube 40. A ratchet gear 43 and a pinion 44 are attached to which the stop portion 38 can be engaged.

Further, the minute hand wheel 39 is meshed and connected to a second hand wheel 46 via a transmission wheel 45, and a second hand 47 fixed to the second hand wheel 46 passes through the main plate 41 and passes through the hollow shaft cylinder 4 of the minute hand wheel 39.
0 is penetrated and protruded.

The second hand wheel 46 is linked to an output shaft 54 of a rotor 53 through a circuit board 48, a fourth wheel 49, a third wheel 50, a second wheel 51, and a first wheel 52.

The rotor 53 has a coil 5 connected to a battery in the power supply room 10 via a circuit block 55 attached to a circuit board 48.
6.

That is, as is well known, the coil 5 is activated by the operation of the circuit block 55.
A current is periodically passed through the coil 56 to generate a magnetic field around the coil 56, thereby rotating the rotor 53.

A transmission wheel 57 that engages with the indicator wheel 11 is rotatably mounted on the boss 4, and is prevented from being removed by a stop pin 58, and a minute wheel 59 that engages with the pinion 44 of the minute wheel 39 is mounted on the vertical pin 5. is pivoted.

Further, the pinion 60 of the minute wheel 59 is meshed and connected to the hour wheel 15.

A needle rotating shaft 63 is supported by a pin 61 in the mechanism chamber 9 and protrudes from a cover 62 mounted on the case 1. A spring force of a spring 64 is applied to the needle rotating shaft 63, and the gear 65 is connected to the transmission wheel 57.
are interlocked and connected.

Further, the fixed contact terminal plates 29 and 30 are respectively connected to a buzzer mechanism 67 and a lighting mechanism 68 which are connected in parallel to a power source 66 as shown in FIG.

Furthermore, the operation of the alarm clock with snooze mechanism of the present invention will be explained in detail.

Now, to apply the battery voltage of the power supply room 10-, the coil 56
The second hand wheel 46, the minute hand wheel 39, and the hour hand wheel 15 are driven through the reduction gear, thereby operating the clock mechanism.

Further, by rotating the needle rotating shaft 63, the indicator wheel 11 is rotated via the gear 65 and the indicator wheel 51, and the indicator wheel 11 can be set at an appropriate time.

When the set time is reached, the claw body hole 14 of the guide car 11 is opened.
When the interlocking pawl 17 of the hour wheel 15 engages, the state shown in FIGS. 3 and 4 changes to the state shown in FIGS. 5 to 1.

That is, since the hour hand wheel 15 comes into contact with the reference wheel 11, the extension part 23 of the push-up spring 18 retracts into the recess 33 of the operation button 31, and the free end 26 of the push-up spring 18 is connected to the buzzer mechanism 67. When the contact terminal plate 29 is contacted, the buzzer sounds.

On the other hand, when the push-up spring 18 contacts the fixed contact terminal plate 29 of the buzzer mechanism 67 and the alarm buzzer is sounding, the buzzer sound is temporarily stopped, that is, when a snooze operation is performed,
When the operation button 31 is pushed from the position shown in FIGS. 5 to 7 to the position shown in FIGS. The inclined tongue piece 24 of the extension part 23 provided at the other end is pushed up so that the extension part 23 rests on the upper surface of the operation button 31, and the free end part 26 of the pressing spring 18 becomes a fixed contact as in the state shown in FIG. Both terminal boards 29 and 30 are separated, and the buzzer sound is blocked.

If the operation button 31 is further pushed from the position shown in FIGS. 8 and 9 to the position shown in FIGS. Then, the free end 26 of the suppression spring 18 contacts the fixed contact terminal plate 30 connected to the illumination mechanism 68, and the clock face is illuminated.

At the same time, the snooze pawl 35 rotates counterclockwise via the rack portion 37, and the ratchet gear 4' of the minute hand wheel 39 rotates.
3 and reaches a position sufficiently spaced from the ratchet gear 43.

If the operating button 31 is released in this state, the snooze pawl 35 will move the operating button 31 back and rotate clockwise due to a suitable spring load, and the locking portion 3 will move as shown in FIG.
8 meshes with the ratchet gear 43 of the minute hand wheel 35.

In addition, when the locking portion 38 of the snooze pawl 35 is rotated by the ratchet gear 43 as the minute hand wheel 39 rotates after a certain period of time has elapsed, the spring load applied to the snooze pawl 35 causes the operation button 31 to close. The extension part 23 of the push-up spring 18 is moved back into the recess 33 of the operation button 31, and the free end 26 of the push-up spring 18 comes into contact with the fixed contact terminal plate 29 again, and the buzzer starts to sound. become.

According to the alarm clock with a snooze mechanism of the present invention configured as described above, the buzzer mechanism and the lighting mechanism can be operated by a single operation button, and the configuration is simple and extremely easy to use. It is possible to achieve effects such as:
