Description

[Detailed Description of the Invention] The present invention relates to an earthquake detection electric light and radio device, and more particularly to an earthquake detection electric light and radio device in which, when an earthquake is detected, a small lamp lights up and a radio starts playing at the same time.

In the past, when a relatively large earthquake occurred, there was a possibility of a power outage, and if this earthquake occurred just after sunset, people could panic because they could not find the whereabouts of their flashlights, candles, bells, etc. It is also necessary to obtain accurate earthquake information using a portable radio, but in the case of an emergency evacuation, there is usually not much time to search for its whereabouts. Further, in the prior art, no electric light radio device suitable for such a case has been provided.

The present invention was made in order to eliminate the drawbacks of the prior art described above, and its purpose is an earthquake detection electric light radio device that lights up a small lamp and simultaneously starts sounding a radio when a relatively large earthquake is detected. Our goal is to provide the following. Another object of the present invention is to provide an earthquake detection electric light/radio device that can simultaneously turn off a small lamp and a radio by activating an earthquake detection canceling device. Still another object is to attach a yoke to the permanent magnet of a radio speaker and form a magnetic path with the yoke to obtain sufficient attraction force, and
It is an object of the present invention to provide an earthquake detection electric light and radio device that does not require a separate magnet for earthquake detection and is simplified, lightweight, and cost-reduced.

The upper body 1a is made of an opaque but translucent material, such as a milky white acrylic resin, and the lower body 1b is made of an opaque material, such as polypropylene. The miniature light bulb 2 is the lower body 1 of the main body 1
It is attached to a frame plate 7 fixed to b. The speaker 3a of the radio 3 is attached to the bottom surface of the lower body 1b, and a cutout portion 1c such as a hole or groove for emitting sound is formed on the circumferential surface of the lower body 1b that the speaker 3a faces. Other parts 3b of the radio 3 are appropriately placed in empty spaces in the main body 1. As the power source 4, two dry batteries 4a are housed in the frame plate 7,
The upper ends of these dry batteries are connected by a conductor 8 made of a metal plate or the like.

The earthquake detection device 5 includes a permanent magnet 3 of a speaker 3a.
an iron yoke 9 which is fixed to c to form a magnetic path of the permanent magnet; a conductor 10 which is attached to one end of the miniature light bulb 2 and suspended downward; and an iron yoke 9 which is fixed to the lower end of the conductor. In a normal state, the magnetic body 11 is suspended at the center of a circular hole 9a formed in the upper part of the yoke 9. Further, the upper part of the magnetic body 11 has a conical surface 11a.
is formed.

The earthquake detection canceling device 6 includes a hollow tube 12 and a shaft tube 1.
3 and a compression spring 14. hollow tube 1
A flange portion 12a formed on the upper part of the main body 1 is pressed against an inner wall 1d of the upper body 1a of the main body 1 by a compression spring 14, and its upper end fits into a hole 1e formed in the upper body 1a and extends outward. It stands out. Further, the miniature light bulb 2 and the conducting wire 10 are housed in the hollow portion 12b of the hollow tube 12, and four pressing pieces 12c are formed at the lower part of the hollow tube 12 to project downward. These pressing pieces 12c are loosely fitted into holes 15a formed in a seat plate 15 fixed to the frame plate 7, and their tips abut against a counterbore 13a formed on the top surface of the shaft cylinder 13. The shaft cylinder 13 consists of a flange part 13b and a shaft part 13c, the flange part 13b fits into the inner peripheral surface of a hollow chamber 15b formed by the frame plate 7 and the seat plate 15, and the shaft part 13c fits into the inner peripheral surface of the hollow chamber 15b formed by the frame plate 7 and the seat plate 15 It fits into a hole 7a formed in 7. Further, the conducting wire 10 is inserted into the hole 13d formed in the axial center of the shaft tube 13 with a sufficient gap. Further, the lower end of the hole 13d has a tapered portion 1 into which the conical surface 11a of the magnetic body 11 can fit.
3e is formed. The compression spring 14 is connected to the shaft cylinder 13
The shaft portion 1 between the lower surface of the flange portion 13b and the frame plate 7
3c, and acts to constantly push the shaft cylinder 13 upward and bring the top surface of the flange portion 13b into contact with the seat plate 15.

As shown in FIG. 2, the upper part of the lower body 1b of the main body 1 is provided with a switch SW ₁ for the miniature light bulb 2, a power switch SW ₂ for the radio 3, and a tuning dial D for the radio 3. .

FIG. 5 is an electrical circuit diagram showing the wiring relationship of each part of the device according to the present invention.

The present invention is constructed as described above, and its operation will be explained below. The main body 1 placed as shown in FIG. 1 has a switch SW ₁ for the miniature light bulb 2 and a power switch SW ₂ for the radio 3 as shown in FIG.
Even if it is set to ON, since the magnetic body 11 is located at the neutral position, that is, at the center of the hole 9a of the yoke 9, no current flows through the miniature light bulb 2 and the radio 3.

In this state, when a relatively large earthquake occurs and the magnetic body 11 shakes with an amplitude above a certain level, the magnetic body 11 is attracted to the yoke 9 forming a magnetic field as shown in FIG. The circuit diagram is the 6th
As shown in the figure, the miniature light bulb 2 lights up and at the same time the radio 3 starts to sound. In this case, if you want to turn off miniature light bulb 2, turn off SW ₁ , and if you want to turn off radio 3, turn off SW ₂ .

In addition, in a weak earthquake, the amplitude of the vibration of the magnetic body 11 is small and the distance from the yoke 9 is large, so the yoke 9 does not reach the point where the magnetic body 11 is attracted.

To release the device that has detected an earthquake in this way, the hollow tube 12 is pressed downward against the spring pressure of the compression spring 14 to lower the shaft tube 13, and a magnetic material is attached to the tapered portion 13e of the shaft tube 13. 11 is inserted into the conical surface 11a. Then, the magnetic material 11 is inserted into the hole 9 of the yoke 9.
The light bulb 2 and the radio 3 go out at the same time.

When the miniature light bulb 2 is lit, the upper body 1a is transparent and is made of, for example, a milky white acrylic resin, so that light passes through to the outside, and the light rays are rich in color.

The present invention is constructed and operates as described above, so that when an earthquake is detected, a small light bulb lights up and the radio starts playing at the same time, so even if an earthquake occurs after sunset, the whereabouts of flashlights, candles, bells, etc. can be tracked. There is no need to search in a hurry, and in the event of an emergency evacuation, the effect is that earthquake information can be accurately obtained from the radio. In addition, since the earthquake detection canceling device can be activated to turn off the miniature light bulb and the radio at the same time, the user does not have to operate each switch for the miniature bulb and radio each time, which is convenient for the user. is obtained. In addition, since a yoke is attached to the permanent magnet of the radio speaker and a magnetic path is formed by the yoke, sufficient adsorption force can be obtained, and there is no need to separately install a magnet for earthquake detection, simplifying the device. The effect of reducing the size, weight, and cost can be obtained.
