Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm true switching mechanism for setting the alarm of an analog alarm crystal clock. Furthermore, the state in which the alarm is waiting to sound and the state in which it has stopped sounding is displayed by indicating the difference in the movement state of the second hand.

As shown in Figure 1, the state of waiting and stopping the alarm in a conventional analog alarm clock is as follows:
Alarm true switching position linked with external operating member,
That is, the difference is indicated by the amount of protrusion of the alarm crown attached to the outer edge of the alarm and the button 1 (hereinafter referred to as the crown) from the watch case 2.

This amount of protrusion is determined by the alarm switching mechanism, but when the alarm stops sounding,
The normal position 1a and the alarm sounding standby state are generally located at the position 1b, which is pulled out one step outward.

At the further protruding position 1c, an alarm setting operation is performed.

This difference in protrusion amount was about 1 mm at most and was not clear. This amount of protrusion is not desirable from the viewpoint of the appearance of the watch while being carried, and also has the disadvantage that the watch 1 is pushed in from the ringing standby state 1b without being aware of the ringing stop state 1a.

The present invention eliminates these drawbacks and will be described below with reference to the drawings.

FIG. 2 is a sectional view showing a switching mechanism for alarm operation using the alarm stem 3 used in the present invention.

Alarm pin 3 shown by the solid line in the figure has its inner end connected to the main plate 1.
2's narrow horizontal hole 12b, the outer part is the wide horizontal hole 1 of the main plate 12
2c in the normal position.

That is, the alarm true switching lever 14 attached to the main plate 12 is guided to the notch 12a of the main plate, and is provided with a vertical elastic force against the bead-shaped part 3d of the alarm true 3, and the corner of the alarm true 3c is engaged with the square hole 4c, and while engaging with the recess 4b, the alarm stopper wheel 4 is brought into contact with the stepped surface 3b of the alarm stem 3, and the outer side of the alarm stem is The alarm lever lever 5 supports the alarm lever 4 with an elastic force in the direction of the lever 21 (FIG. 3) attached to the end, and the alarm lever lever 5 is in elastic contact with the inner wall 12a of the main plate 12 while hitting the tip 3d of the alarm lever. The alarm stem lever 6 is attached to the main plate 12 and has an elastic force that pushes the alarm stem 3 toward the rear end 21 in contact with the alarm stem lever 6.

Next, as shown in FIG. 3, when the lever 21 in the normal position is pushed into the position 21-(1), the alarm stem connected to it is connected to the lever 5 and the alarm via the lever 4. Against the elastic force of the true lever 6, the alarm true switching lever 14
The alarm stem 3 moves inward to the position 3-(1) where the stepped wall 3e of the alarm stem 3 comes into contact with the outer tip outer surface 14a of the alarm stem 3 and is stopped. At this time, the alarm tsuzumi car 4 is
-(1), the alarm lever 5 is in the 5-(1) position, and the alarm true lever 6 is in the 6-(1) position, and is molded from plastic and bonded by thermocompression to the electronic circuit board 16 via the circuit receiver 7. An alarm contact lever 15, which is fixedly connected to an electronic circuit (not shown), contacts the alarm true lever 6 at a position 15-(1).
Then, a signal from the electronic circuit is transmitted to the buzzer and the step motor, and the signal is further transmitted from the step motor to the time display hand via the wheel train. Furthermore, when the pushing force of the rear arm 21 pushed into the position 21-(1) is removed, the rear arm is automatically moved to the normal position 2 by the elastic force of the alarm stem 6.
Return to 1. At this time, the alarm contact spring 15
Contact with the alarm true lever 6 is also released.

On the other hand, when the reuse 21 is moved outward from the normal position 21 and placed in the first drawer 21-(2), the alarm stem 3 interlocked therewith moves to the position 3-(2).

That is, the tip 1 of the alarm true switching lever 14
4b crosses over the slope of Alarm Shin 3's solo ban ball 3f and enters valley 3g, and Alarm Shin 3-(2)
It switches to the position. At this time, the alarm wheel 4 is moved by the elastic force of the alarm wheel lever 5.
- Move to the position (2), and the tooth 4d of the alarm stop wheel 4 meshes with the tooth 7a of the alarm stop wheel 7, which is in contact with the main plate 12. Alarm kitty car back teeth 7
b meshes with an air transmission wheel 8 bearing on the main plate 12 and back plate 13;
It meshes with the cylindrical teeth 9b of the display ring 9 supported by the dial plate receiving ring 10. A part of the date wheel 18 and day wheel 19 supported by the date wheel pusher 20 on the main plate 12 can be seen through the dial window 11a.

Next, one embodiment of the use of the alarm clock of the present invention will be described.

First, the method for setting the alarm is to pull out the alarm crown 21 which is in the normal position to the position 21-(2), and as explained above, the Oto tooth 4d of the alarm stop wheel and the O tooth 7a of the alarm stop wheel. mesh together.

Here, when the lever 21 is rotated, the rotation of the alarm stopper wheel 4, alarm stopper wheel 7, transmission wheel 8, and display ring 9 is transmitted from the interlockingly rotating alarm stem 3. As described above, the display ring 9 is rotated so that the buzzer set mark 9a marked on the display ring 9 is aligned with the buzzer set scale 11b on the dial 11 indicating the time at which the buzzer is to sound. In the case of Fig. 3, the time is set at 12 o'clock.

Continuing, when the reset lever 21 is pushed in from the position 21-(2) to the position 21-(1), the alarm true lever 6 comes into contact with the alarm contact spring 15, and the signal from the electronic circuit causes the buzzer to emit a single sound "Pitsu". The alarm setting confirmation sound will sound, and the second hand 22 will move in 1-second steps every n seconds, which is the normal movement of the second hand 22.
The hand changes to n-second step movement to indicate that the alarm is waiting to sound. The electronic circuit may be designed by selecting n of the n seconds from 2, 3, 4, 5, etc.

If the pushing force on the rear seat 21 has already been released, the rear arm 21 will automatically return to the normal position 2.
1 is as explained above.

Next, the process from opening the alarm sound at the set time to canceling the alarm, that is, stopping the sound from sounding, will be explained. At the set time, an alarm switch (not shown) arranged in the rear wheel train is turned on and a buzzer starts sounding. To open the buzzer and then stop it from ringing,
All you have to do is hold the reuse 21 in position 21-(1) again. Then, the alarm sound stops due to a signal from the electronic circuit, and the second hand moves from the n-second step back to the normal 1-second step, indicating that the alarm has been released.

As described above, according to the present invention, the waiting state of the alarm can be determined by the movement of the second hand, so it is clear at first glance.

This eliminates the need for identification based on the amount of protrusion of the crown, as was done in the past, and the appearance of the phone is not compromised, and there is also the disadvantage that if the crown is pushed in unknowingly, it will not ring at the set time. It disappears.
