Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm setting device for an alarm clock.More specifically, when an alarm is issued, the alarm can be stopped by pressing a button, and if left as it is, the alarm can be set at the same time the next day. This invention relates to an automatic alarm setting device that issues an alarm again.

With conventional alarm clocks, when the alarm goes off at the set time, the alarm is stopped by pressing a button commonly called the stop button, and if you want to use the alarm again after that, turn on the stop button.
I had to maneuver in the direction.

However, when setting the alarm at the same time every day, the user has to press the alarm button each time to set the alarm each day, which is very troublesome.

In order to overcome these drawbacks, automatic return devices that automatically return via a slip mechanism have been proposed in the past (for example, Japanese Utility Model Publication No. 44123/1983), but the structure is complicated and the cost is high. It has the following drawbacks.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the troublesomeness of setting the alarm time as described above, and to simplify the structure and manufacture it at low cost.

The present invention is characterized by: an operation plate that is movable from a first position to a second position and is biased in a direction from the second position to the second position;
When the operation panel is in the first position, the sound is enabled.
There is an alarm device that is in a state in which it cannot sound when it is in the second position and generates an alarm at the alarm set time when it is in a state in which it can be sounded, and is rotatably provided on the operation panel, and the operation panel is moved to the second position. a lock lever that engages with the position holding member to hold the operating plate in the second position; and a lock lever that is provided to move together with the operating plate, when the operating plate moves to the second position; An operating gear that can mesh with the constant speed gear, and a lock lever that is provided on the operating gear so that it can engage with the lock lever.
a release member that engages with the lock lever when the operating gear is rotated by the constant speed gear to rotate the lock lever and release the lock lever from holding the operating plate in the second position; the operating gear and the constant speed gear; The gear is equipped with a return spring that rotates the operating gear to return to its initial position when the gear is disengaged from the operating gear.

The embodiments shown in the drawings will be described below.

First, the structure of the first embodiment shown in FIGS. 1 to 4 will be explained. Reference numeral 10 denotes an hour hand gear which is rotatably supported by the substrate and is a constant speed gear that rotates counterclockwise in order to display the time and rotates once every 12 hours. Alarm device X consists of switches SW ₁ , SW ₂ , SW ₃
and buzzer B. Although the second switch SW ₂ is not shown, it is configured to operate in conjunction with a reference gear provided corresponding to the hour hand gear, so that the reference gear is moved and closed when the wake-up time arrives. Further, the third switch _SW3 is linked to the set button 11 which is operated when using the alarm mechanism, and is closed when the alarm is set. The first switch _SW1 is a normally closed switch that can be associated with the operation panel 1, which will be described later. The power source E, the buzzer B, the first switch SW ₁ , the second switch SW ₂ and the third switch SW ₃ are connected in series, and the buzzer B is activated when the three switches are closed. The operation plate 1 has a groove 1a, and the groove 1a engages with a pin 2a set on the board, so that the operation plate 1 is guided so as to be movable up and down, and is placed in a first position (first position). (position shown) to a second position (second position shown). Further, the operation plate 1 has a lock lever 3 rotatable about a shaft 4 at the left end, a control lever 6 rotatable about a shaft 5 at the lower end, and a pin 7 to be described later and a counterclockwise rotation of the control lever 6. It has a pin 8 that regulates rotation in the direction.
The lock lever 3 has a pin 1 that engages with a heart cam 12 as a position holding member formed on the base plate.
3, a spring hook pin 14, and a cam portion 3a to be described later, and the spring hook pin 14 and the spring 15 hooked to the fixed end provide a restoring force on the line connecting the center of the heart cam and the shaft 4. It is being Furthermore, the spring 15 acts on the operating plate 1 via the lock lever 3, providing upward return sliding ability. The control lever 6 is always given a counterclockwise rotational force by a spring 16, and has an operating gear 18 at its tip so as to be rotatable about a shaft 17. The operation gear 18 is capable of engaging with the cam portion 3a of the lock lever, and has a pin 20 as a release member for swinging the lock lever 3, and is always given counterclockwise rotational force by a return spring 19. The rotational force is supported by a pin 21 mounted on the gear that abuts against the side surface of the control lever 6. The heart cam 12 of the substrate is formed in detail as shown in FIGS. 3 and 4. That is, the pin 13 of the lock lever 3 is always applied with a restoring force in the upward direction (in the direction of the first position) as described above. Therefore, operation panel 1
When pressed down, the pin 13 descends in a straight line and first hits the first surface 12a of the heart cam, and when the operation plate 1 is pushed down to the maximum, the pin 13 reaches the first bottom dead center 12.
It hits point b and stops. Here, when the above pushing is released, the pin 13 moves while turning to the right due to its own restoring force, and as the pin 13 hits the cam surface 12c, the operation plate 1 stops rising, and the operation plate 1
is held in the second position shown in FIG. In this second position, the operation gear 18 and the hour hand gear 10 are configured to mesh with each other, and the pin 7 of the operation plate operates the first switch _SW1 to open it. From this state, the operation plate 1
When the pin 13 is pushed in, the pin 13 will now touch the cam surface 12.
d, and further climbs over the slope portion 12e and hits the bottom dead center 12f. When the operation plate 1 is released, the pin 13 tries to return upward due to its own restoring force, but the pin 13
It is not possible to turn left after hitting 2e. Therefore, as the operation plate 1 rises, the pin 13 moves up the slope 12.
Top dead center 1 while being guided by the side of e and 12g
2h, the operation plate 1 returns to the first position shown in FIG.

Next, the operation of the above structure will be explained. First, press the set button 11 to wake up.
When set to the ON position, the third switch _SW3 is closed. When the clock is left unattended in this way and the alarm time arrives, the second switch SW ₂ is turned on. At this time, the first switch SW ₁ and the third switch SW
is in the ON state, so buzzer B starts sounding. In this case, there are two ways to stop the operation of the buzzer B, one of which is to operate the set button 11, which is similar to the permanent ringing device of a general alarm clock. When the set button 21 is set to the off position, the third switch _SW3 is opened and the buzzer B stops sounding. The second method is to operate the operation panel 1, and its operation will be explained in detail below.

When the buzzer B is operating, when the operation plate 1 is first pushed in, the pin 7 engages the first switch _SW1 and opens the latter, so the buzzer B stops sounding. At this time, the lock lever 3 and control lever 6 attached to the operation plate 1 are also lowered at the same time. As a result, the pin 13 of the lock lever 3 descends along the first surface 12a of the heart cam as described above, and the first
It reaches the bottom dead center 12b, and the downward movement of the operation plate 1 stops here. During this movement, the operation gear 18 attached to the control lever 6 meshes with the hour hand gear 10, and when the control lever 6 is pushed beyond the normal engagement, the control lever 6 rotates clockwise against the spring 16. Nigeru. When the operation plate 1 is released from this state, the operation plate 1 starts to move upward due to the force of the spring 15, but the pin 13 of the lock lever has a rightward rotational force, so the second cam It rises along the surface 12i, and eventually hits the cam surface 12c, and the upward movement of the operation plate 1 stops, resulting in the state shown in FIG. 2. At this time,
The above-mentioned hour hand gear 10 and operation gear 18 are formed to mesh properly. If the watch is left in this state, the operating gear 18 will shift to the hour hand gear 10.
It is driven by and rotates clockwise. and,
When the operating gear 18 is driven for a predetermined period of time, the pin 20 fixed to the operating gear 18 hits the cam surface 3a of the lock lever, and with continued rotation, the pin 20
0 rotates the lock lever 3 clockwise. As a result, the pin 13 of the lock lever is connected to the cam surface 12.
It moves to the right along line c, and eventually climbs over the slope part 12e of the heart cam. Then, since there is no longer anything to regulate the upward movement force of the operation plate 1, the operation plate 1 moves upward by the force of the spring 15, and the heart cam 12 reaches the top dead center 12h.
It hits and stops. As a result, the operation plate 1 returns to the first position shown in FIG. With this upward movement, the operation gear 18 first moves to the hour hand gear 10.
The operation gear 18 is disengaged from its own spring 1.
9, the first switch rotates counterclockwise and returns to the state shown in FIG.
SW ₁ is closed again. However, at this time, the hour hand gear 10 has already rotated for a certain period of time since it started sounding, and the second switch SW ₂ is open, so the buzzer B does not operate.

Here, the temporal operation of each switch will be explained with reference to FIG. This diagram shows the case where the operation panel 1 is used as a noise stopper, and as mentioned above, first the third
Switch SW ₃ is closed by set button 21. In addition, the first switch SW ₁ is initially installed on the operation panel 1.
is not activated, so it is in a closed state. In this state, the hour hand gear 10 on which the clock is installed rotates, and when the alarm time arrives, the second switch SW ₂ is closed, all switches are closed, and the buzzer B starts operating. At this time, if you push in the operation panel 1 to stop the buzzer B, the first
Switch SW ₁ is released and buzzer B stops sounding.
If the watch is left in this state, the hour hand gear 10 rotates, out of phase with the reference gear, and the second switch _SW2 is opened. However, in this case the first
For example, if we consider a 12-hour analog clock that does not have switch SW ₁ and the time rotates once every 12 hours, the second switch SW ₂ will be closed again after 12 hours.
The buzzer B will start sounding, but in the present invention, a first switch SW ₁ is newly provided, and this is associated with the operation plate 1 controlled by the operation gear 10 and the lock lever 3. SW ₁ until the second closing of the second switch SW ₂
The off state is maintained. Therefore, the buzzer B will not operate due to the second closing of the second switch _SW2 . The above-mentioned lifting of the operating plate 1 to the top dead center by the action of the operating gear 18 and the lock lever 3 is performed between the second and third closing of _the second switch SW2. Therefore, due to this rise, the first switch _SW1 is closed again, and the second switch _SW2 is closed at the same time as the alarm time set on the previous day, for example, and the buzzer B starts sounding. By repeating this process, the user can get up at the same time every morning, but if he sets the alarm every day, he will no longer have to worry about getting up at the same time. However, in such a device, if the alarm time that has been set has to be set to a different time, it is necessary to release the operation panel 1 from the pressed state as shown in FIG. In such a case, when the operation plate 1 is pressed in the state shown in Fig. 2, the pin 13 of the lock lever 3 will move against the cam surface 12d.
It descends along the slope and eventually climbs over the slope portion 12e. If the push-in of the operating plate 1 is released in this way, the cam that restricts the pin 13 of the lock lever disappears, so the operating plate 1 rises to the top dead center of the heart cam 12, and all mechanisms are activated as shown in FIG. Since it is possible to return to the current state, all you have to do is set the alarm time anew.

Next, FIGS. 6 and 7 show a second embodiment,
In contrast to the first embodiment, an embodiment in which the automatic setting operation is canceled by a different means and an alarm device using mechanical vibration is used will be described below. In FIG. 6, an operating plate 101 that can be moved up and down to operate the automatic alarm setting device rotatably supports a lock lever 103 and a control lever 106 that rotatably supports an operating gear 118 similar to the first embodiment. It has a pin 107 associated with a diaphragm 124 that is associated with the stator of an AC motor 128 and generates an alarm sound. Then, the spring 123 causes the operation plate 10 to
1 is always biased upward. In order to lock the operation plate 101 in the pushed-in position, the lock lever 103 has a claw portion 1 that engages with a hook portion 122 as a position holding member provided on a board (not shown).
03b and an arm portion 1 that engages with a pin 120 as a release member provided on the operating gear as in the first embodiment.
03a, and is biased counterclockwise by a spring 115 provided between it and the operation plate 101. A control lever 106, an operating gear 118 rotatably provided on the control lever 106, a return spring 119 that urges the operating gear 118 counterclockwise, and a part of a clock train mechanism operated by an AC motor 128. Alternatively, the relationship of the related operating gear 118 is the same as in the first embodiment, so the explanation will be omitted. Alarm device Y
is composed of a diaphragm 124 and a stator of an AC motor 128. The diaphragm 124 is made of a magnetic material, and includes a vibrating piece 124a that vibrates in contact with or near a part of the stator of the known AC motor 128 to generate an alarm sound, and a vibrating piece 124a that engages with the pin 107 of the operation plate. The first arm part 124b engages with the manually operable set button 121 to issue a wake-up alarm. Alternatively, in a known standard time detection device that activates an alarm device by moving either one of the standard cars, it has a second arm portion 124c that engages with a detection member 126 that operates in conjunction with the movement, and It is biased clockwise by a leaf spring 125. When the operating plate 101 is in the set position, the diaphragm 124 is connected to the operating plate pin 1 as shown in FIG.
07 and the first arm portion 124b engage with each other, and the diaphragm 1
24 rotates counterclockwise, and the AC motor 128
When the stator and the vibrating piece 124a do not emit an alarm sound and cannot sound, and the operation plate 101 is in the release position as shown in FIG.
7 and the first arm portion 124b are in a disengaged state,
It is rotated clockwise by the diaphragm spring 125 and can be vibrated by the stator and the vibrating piece 124a. In addition, a detection member 126 and a vibrating element second arm 1 that operate at a predetermined time once every 12 hours.
24c is in the engaged state, the diaphragm 124 is rotated counterclockwise as shown in FIG. It becomes possible. Furthermore, set button 1
21 is set to the OFF position, the set button 121 and the diaphragm second arm 124c are engaged, the diaphragm 124 is rotated counterclockwise, and the ringing is disabled in the same manner as above, and the diaphragm 124 is set to the ON position. In this case, the second arm portion 124c is not engaged with the second arm portion 124c, and an alarm can be issued in the same manner as above. Therefore, the diaphragm 124 is regulated by three parts, the operation plate 101, the detection member 126, and the set button 121, to issue an alarm.
The release lever 127 can be operated manually in order to forcefully release the release lever 127 when the operating plate 101 is locked in the set position by the lock lever 103 and the hook portion 122, and the pin 127a that engages with the lock lever can be operated manually. and is biased clockwise by a spring 129.

Next, the operation of the second embodiment having the above configuration will be explained.

FIG. 6 shows the state before the automatic set operation and when the automatic set is released, in which the hour hand gear 110 and the operating gear 118 are in a non-meshing state, and the diaphragm 124 is in a non-engaging state with the pin 107 of the operating plate. At the same time, the set button 121 is set to the ON position in order to issue an alarm at a predetermined time, and is not engaged with the second arm portion 124c of the diaphragm. However, when the detection member 126 related to the reference time detection device and the second arm portion 124c of the diaphragm are engaged, the oscillation piece 124a of the diaphragm is retracted to a position not related to the stator of the AC motor 128. However, after a certain period of time has elapsed and at a predetermined time, the detection member 126 moves to the left by the reference time detection device and becomes disengaged with the second arm portion 124c. , the diaphragm 124 is rotated clockwise by a spring 125, and the vibration plate 124a and the AC motor 1
An alarm sound is generated by the stator section 28.

Next, the operation of the automatic setting device which issues a warning again after 24 hours as in the first embodiment will be explained. First, when the operation plate 101 is operated downward to stop the alarm, the operation plate pin 107 and the first arm portion 124b of the diaphragm are engaged, the diaphragm 124 is rotated counterclockwise, and the alarm is stopped. On the other hand, by operating the operation plate 1, the operation gear 118 meshes with the hour hand gear 110, which is a constant speed gear, and becomes interlocked with the clock train mechanism.
22 is in the locked state, and the operation plate 101 is held at the set position, as shown in FIG. Operation gear 11
8 in the clockwise direction, the pin 120 of the operating gear engages with the arm portion 103a of the lock lever after the set time elapses in the same manner as in the first embodiment, and the claw portion 103b of the lever engages with the hook portion 122. When the lock is released, the operation plate 101 is moved upward by the spring 123 and stops at the position. With the operation of the operation plate 101, the operation plate pin 107 and the diaphragm 124 are disengaged, and the operation gear 118 is disengaged from the clock gear 11.
0 and is in a non-meshing state, and is restored to the initial position by the spring 119. After a certain period of time has passed in this state, the detection member 126 is activated at a predetermined time, and the diaphragm 124 issues the first alarm.
This test was carried out after 24 hours as in the example. Furthermore, if you wish to forcibly stop the automatic setting operation, by manually operating the release lever 127, the release lever 127a and the lock lever 103 are engaged, and the claw portion 103b of the lever is engaged with the release lever 127a.
The locking of the hook part 122 is released, and the operation plate 101
is released. In addition, if you wish to issue an alarm within 12 hours when the automatic setting device is not activated, please
The sound can be stopped by operating the set button 12 without operating the button 01.

As described above, according to the present invention, for example, in an alarm clock having a 12-hour display and a guide mechanism, an alarm is issued at a fixed time every day by providing a means for preventing an alarm by a guide detecting device after 12 hours. When necessary, all you have to do is operate the operating member that activates the automatic setting device to stop the alarm.
It is easy to change the standard set time and to cancel the automatic setting device when the next day's alarm is not required, and it is possible to freely select between normal alarm operation and automatic setting operation. Moreover, since the structure is simple, it can be manufactured at low cost.
