Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a signal device used in a distress situation that generates a response signal in response to a radar signal, and particularly to the structure of its switch section.

[Conventional technology]

Conventionally, the structure of the switch section of this type of device has been a mercury switch that opens when the switch is inverted and closes when the switch is turned upside down.

Such a switch is attached to the main body of the signal device, and the main body of the signal device is normally stored in an inverted position and oriented in the normal direction when in use.

By doing this, it is not necessary to turn the switch on or off from the outside, so that it is possible to automatically enter the operating state without turning on the switch during use. Although a switch mechanism having such a function is rarely used, it is extremely important in this type of signaling device, which requires reliable and automatic switching when in use.

[Problem that the invention attempts to solve]

Since the conventional device is configured as described above,
On the other hand, there were restrictions on the installation of signaling equipment, and as a result, special measures were required for the signaling equipment and its installation equipment.

This idea was made to solve the above problems, and was designed to meet the requirements of a special-purpose switch called a signal device, that is, to automatically close the switch when in use, and with fewer installation restrictions. The aim is to obtain a division.

[Means for solving problems]

The structure of the switch section of the signal device according to this invention uses a magnetic switch in the switch circuit that opens when the magnet is brought close and closes when the magnet is moved away. When the valve is closed as a watertight stopper, a magnet is disposed beside the magnetic switch to open the switch circuit.
In an emergency, the magnet is moved away from the magnet switch by removing the waterproof plug, the switch circuit is closed, and the power to the signal device is turned on.

Note that by closing the waterproof plug, the signal device is completely waterproof from the outside at all times, but when in use, by opening it, the sound from the waterproof speaker provided inside the signal device is guided to the outside.

[Effect]

Since I don't use the signal device all the time, I open the magnetic switch and turn off the power. At this time, it does not consume electricity at all, so it lasts a long time. Also, since it is in a closed state, it is completely sealed from the outside and can maintain reliability for a long period of time.

In an emergency, when the signal device is placed in use, the valve will be opened semi-automatically, the power will be turned on, and the sound from the speakers will be directed outside.

[Example of idea]

Examples of this invention will be described below. FIG. 2 is an external view of the life raft on which the signaling device 1 is mounted.
Note that the signaling device 1 is in use. A canopy 3 is placed over the floating ring 2, and the signal device 1 is mounted on it in an upright state. The structure of the signal device 1 is as shown in FIG. 11 is the antenna/electronic circuit section,
When a radar radio wave is received, a predetermined signal in which a plurality of predetermined bright spots appear on the radar display is used as a response signal, and the vehicle takes off. 12 is the battery section, 13 is the sound
The switch part 14 is a pull string. In addition, when in use, the pull string 14 is pulled and removed from the signal device 1.

The details of the sound switch section 13 are shown in FIG. 1 in a sectional view.

FIG. 1A shows the frame 1331 normally attached, and FIG. 1B shows the frame 1331 being removed by pulling the string 14. 131 is the outer cylinder;
1 is the packing, and 1312 is the A thread part. 1
Reference numeral 32 designates a sound switch section, which includes a prevention plate speaker 1321, a magnetic switch 1322 for power switch, a screw section 1323 for attaching the sound switch section 132 to the outer cylinder 131, and a screw section 1323 for attaching the sound switch section 132 to the outer cylinder 131. It is composed of a sound hole part 1324 that guides the sound hole to the outside. The magnet part 133 attaches the frame 1331 to the outer cylinder 131 B
It consists of a threaded part 1332, a grip part 1333 to be held when attaching the frame 1331 to the outer cylinder 131, a string hole 1334 for tightening the string 14, a magnet 1355 that acts on the magnetic switch 1322, and a groove 1336 into which the magnet 1355 is fitted. Ru. Note that the frame body 1331 is
33 in the rotational direction, use the A thread part 1312
and the B screw part 1332 are engaged with each other and the magnet part 13
22 is attached to and detached from the outer cylinder 131, but if you pinch the handle part 1333 and move it inward, the A threaded part 1
312 and the B screw portion 1332 are removed, and the magnet portion 133 is removed from the outer cylinder portion 131.

Next, the operation will be explained. When the frame 1331 is normally attached to the outer cylinder 131, the frame 1331
and the outer cylindrical portion 131 are the respective A threaded portions 131.
2. The B screw part 1332 is fitted and held, and the packing 1311 makes it waterproof. Furthermore, the magnet 1335 is the magnetic switch 1.
Magnetic switch 13 is placed beside 322.
22 is in an open state. Therefore, the power supply is
The inside and outside of the OFF signal device 1 are completely cut off.

Next, when the inflatable life raft is put into use, the string 14 is pulled when the raft is placed on the self-expanding canopy 3 of the inflatable life raft.
As shown in FIG. B, the frame body 1331 comes off from the outer cylinder 131 due to the flexure and the space between the A threaded part 1312 and the B threaded part 1332 comes off.

Then, the magnet 1335 separates from the magnet switch 1322 and the magnet switch 135
5 is closed and the power is turned on, the front surface of the plate-shaped speaker 1321 is also opened and the sound can be heard through the sound hole.

The pull string 14 is attached to the signal device 1 in a state where no force is applied when it is stored, but when it is in use, force is applied to the pull string 14 by pulling it by hand or by standing the signal device up. I try to remove it.

Furthermore, after use, A thread part 1312 and B thread part 1
332 is engaged, and when the grip part 1333 is turned and fitted, the magnetic switch 1322 opens and the power is turned off.

[Effects of the invention] As described above, according to this invention, a magnetic switch is used as the power switch of the signal device, and the lid is normally closed with a magnet embedded in the magnet. Open the switch to turn off the power, keep the inside of the signal device sealed from the outside, and when in use, turn off the power by removing this magnet part.
When the signal device is turned on, the lid of the signal device is removed, and the speaker sound is guided to the outside, which has the effect of providing a highly reliable signal device.
