Abstract

PURPOSE: To give an alarm only at the time of the occurrence of an earthquake stronger than a fixed value by incorporating an earthquake alarm mechanism into an alarm clock. CONSTITUTION: When an earthquake stronger than a fixed value occurs during sleeping, a changeover switch 4 is changed over to the contact (a) side, an arbitrary time is set previously by the time setting knob of an alarm mechanism A and an operating switch 11 is turned on for emitting a warning sound. Consequently, the mechanism A is brought to the state of operation while a current is also made to flow through a timer 5, an alarm clock is installed at a specified place after ten and several or several dozen sec passes, a relay 51 is short- circuited when vibrations are not applied to the alarm clock, and an earthquake alarm mechanism B is brought to the state of operation. When a fixed time passes, the alarm clock reaches a set time and the relay 21 of the mechanism A is short-circuited or the switch 11 is turned off before the alarm clock reaches the time, the relay 51 is turned off, and the mechanism B is returned to an original state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm clock equipped with an earthquake warning mechanism.

[0002]

2. Description of the Related Art When an earthquake of a certain magnitude or more, such as a strong earthquake or a strong earthquake, occurs, furniture may fall over in the house or walls may fall off, resulting in injury, resulting in a tsunami. There may be external damage due to landslides and landslides. Even when such damage does not occur, it may suffer secondary damage caused by a fire. Therefore, when an earthquake occurs, it is necessary to immediately deal with the disaster and evacuate. In order to minimize human damage when an earthquake occurs, in areas where there is a fear of occurrence of earthquakes, there is an alarm system by broadcast radio, and when an earthquake occurs, an alarm is issued and the area is issued. In addition, each home is equipped with a device that automatically turns on the TV and gives an alarm when an earthquake occurs.

[0003]

Since the same damage occurs when an earthquake occurs at night, it is important that a sleeping person also immediately wakes up when an earthquake occurs. However, even if an earthquake occurs when you are asleep, not everyone will wake up feeling the shaking. In particular, when sleeping, the room is completely closed, so even if an alarm sound is emitted from the above-mentioned alarm device installed outdoors or a TV set in the living room, the sound is emitted. You can hardly expect to be awake. Therefore, conventionally, when an earthquake of a certain level or more occurs, an earthquake alarm that senses it and emits an alarm sound is attached to the wall of the bedroom,
Attempts were made to incorporate it into the table clock. However, this earthquake alarm has a problem that an alarm sound is emitted each time the room is cleaned, the wall is hit by the body, or the furniture is moved. So, trying to eliminate such a problem, if you install it in a place where it is hard to reach such as a high position on the wall or the ceiling, there is a problem that once the buzzer sounds, it can not be stopped, It could not be put to practical use. The present invention provides an earthquake alarm that emits an alarm sound when an earthquake occurs while a person is sleeping and does not generate an alarm sound by performing vibration by cleaning or moving an object. Is intended.

[0004]

SUMMARY OF THE INVENTION The present invention provides an alarm clock in view of the fact that the alarm clock is placed on the bedside of a sleeping person, and the alarm mechanism is activated only while the sleeping person is sleeping. With the built-in seismic warning mechanism, connect the seismic warning mechanism to the wake-up mechanism, set the wake-up time of the wake-up mechanism, and activate it. Then, the seismic warning mechanism is also configured to be released from the operating state. In particular, when a timer is attached to the earthquake alarm mechanism and the alarm mechanism is activated, the earthquake alarm mechanism is activated after a delay of 10 to 10 seconds, and the alarm mechanism was set first. The above-mentioned object is achieved by means of which the operating state is released when the time is reached. Even if the alarm mechanism is activated, the earthquake warning mechanism can be configured not to be activated, and the earthquake alarm mechanism can be activated without the alarm mechanism activated. You can also do it. The seismic warning mechanism may be an embodiment configured to emit a warning sound and a light at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An alarm clock equipped with an earthquake warning mechanism according to the present invention will be specifically described below based on the illustrated embodiments. In this embodiment, the alarm clock comprises a clock mechanism (not shown), an alarm mechanism A, and an earthquake warning mechanism B. The clock mechanism and the alarm mechanism A are similar to a normal alarm clock, and the clock mechanism displays the time of day, and the alarm mechanism A is configured to sound a buzzer at a predetermined time. It was done. First, the alarm mechanism A will be described with reference to a block system diagram. In this figure, circuit diagrams of switches and relays (for example, self-holding circuits) are omitted. In the figure, reference numeral 1 is an operation switch mechanism, 2 is a time setting mechanism, and 3 is a buzzer. The operation switch mechanism 1 is for switching the alarm mechanism A to an operating state (a state where a buzzer sounds at a predetermined time) and releasing it, and has a switch 11 and a switch button for operating it. The switch button is projected to an appropriate position on the back surface or the top surface of the timepiece so that the switch 11 mounted inside the timepiece can be switched. The time setting mechanism 2 has a normally open relay 21 and a time setting knob. When an arbitrary time is set by the time setting knob, the time is displayed on the dial of the clock and the time is set. After that, a predetermined time has passed, and at that time, the relay 21 is short-circuited for several tens of seconds. The switch 11 of the operation switch mechanism 1, the relay 21 of the time setting mechanism 2, and the buzzer 3 are connected in series, and when the switch 11 is short-circuited, the set time is reached and the relay 21 is short-circuited. The buzzer 3 sounds only for a while.

Next, the seismic warning mechanism B will be described with reference to a block system diagram, which comprises a changeover switch 4, a timer 5, an earthquake sensing mechanism 6, and an alarm device 7. The change-over switch 4 has two contacts a and b, and is adapted to switch between a short-circuited state with the contact a, a short-circuited state with the contact b, and a neutral state. The contact a is connected to the switch 11 of the alarm mechanism A, and the contact b
Is directly connected to the power supply circuit, and if this is short-circuited with the contact point a, the alarm device 7 will be activated when an earthquake occurs while the alarm mechanism A is in the activated state, and short-circuited with the contact point b. Then, regardless of whether or not the alarm mechanism A is activated, the alarm device 7 is activated when an earthquake occurs. If the changeover switch 4 is set to the neutral position, the alarm device 7 will not operate even if an earthquake occurs. The timer 5 has a delay circuit and a normally open relay 51, and is provided with the changeover switch 4 or the switch.
When the switch 11 is turned on, the relay 51 is short-circuited after a tens of seconds to several tens of seconds have passed since then, and the earthquake warning mechanism B is activated. Further, in this embodiment, the reset circuit of the relay 51 is connected to the timer 5 and is connected to the relay 21, and the energization of the timer 5 is stopped, or the relay 21 is short-circuited at the set time. Then, the relay 51 immediately returns to the original open state, and the operation state of the earthquake warning mechanism B is released. The seismic sensing mechanism 6 has a sensing element for sensing shaking of a certain level or more and a normally open relay 61, and when the sensing element senses shaking, the relay 61 is short-circuited immediately.
The seismic detection mechanism 6 is also connected to the relay 61 return circuit, and when the seismic detection mechanism 6 is de-energized, the relay 61
Will immediately return to its original open state. The alarm device 7 has a warning sound generator such as a buzzer,
When it is energized, a warning sound is emitted.
If necessary, a light 8 such as a fluorescent tube is attached in parallel with the alarm device 7 so that a warning sound is emitted and at the same time the light 8 is turned on to light up the room. The earthquake warning mechanism B is a relay of the changeover switch 4 and the timer 5.
51, the relay 61 of the earthquake detection mechanism 6 and the alarm 7 are connected in series, and when the changeover switch 4 and the relay 51 are both short-circuited, when the clock shakes due to an earthquake or the like,
The relay 61 is short-circuited, the alarm device 7 is activated and a warning sound is emitted, and at the same time, the light 8 is turned on.

When an earthquake occurs while sleeping, an alarm sound is emitted (when an earthquake occurs while the alarm is set, an alarm sound is emitted). Put it on the a side. Then, the alarm mechanism A is operated in the same manner as in the normal case. That is, set an arbitrary time with the time setting knob,
Turn on the operation switch 11. Then, at the same time that the alarm mechanism A is activated, a current also flows through the timer 5, and after several tens of seconds to several tens of seconds have elapsed, the alarm clock is placed at a predetermined position and the vibration is not applied to it. By the way, the relay 51 is short-circuited, and the earthquake warning mechanism B is activated. Further, when a predetermined time has elapsed and the set time has been reached, the relay 21 of the alarm mechanism A is short-circuited, or the operation switch 11 is turned off before the time is reached, the relay 51 is turned off and the earthquake warning mechanism B is activated. Return to the original state.

[0008]

As described in detail above, the present invention is an alarm clock equipped with an earthquake warning mechanism, and in particular, whether or not the alarm mechanism of the alarm clock is actuated, that is, this alarm clock. Or use as an alarm clock,
There is an advantage that an earthquake warning mechanism can be used regardless of whether it is used as a simple clock. Moreover, by attaching a timer to the seismic warning mechanism so that the seismic warning mechanism does not become active until a dozen or more tens of seconds have passed since the electric current flowed through the seismic warning mechanism, the operation switch of the alarm clock was activated. When you put it in or put it in place such as at the bedside, it will not make a warning sound even if vibration is applied to it, and it will make a warning sound even if the alarm buzzer sounds at the set time. Therefore, the alarm clock has the advantage that even if the changeover switch 4 of the earthquake warning mechanism is turned on, it can be used in the same manner as a timepiece without this mechanism.
