Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can wirelessly transmit a distress signal when a person is alive due to a disaster such as an earthquake or is in a dangerous state due to a seizure or an intruder while sleeping. It relates to the device.

[0002]

2. Description of the Related Art Hitherto, as a device capable of transmitting a rescue signal by radio in an emergency, a rescue signal transmitting device for mountain distress or marine distress and various wireless communication devices have been used.

[0003]

However, the conventional wireless rescue signal transmitting device and wireless communication device are devices that are supposed to be carried by the user. Therefore, they could not exert their functions in case of an emergency while sleeping without carrying such a device. For example, in the case of a disaster such as the Great Hanshin-Awaji Earthquake that occurred before dawn on January 17, 1995, all the bedding would be buried and it would be impossible to move. Even if a signal transmission device was prepared, it was impossible to activate it and transmit a rescue signal.

The present invention provides a rescue signal transmitting device which can be activated even in such an emergency situation during sleep, and enables a reliable rescue work as soon as possible to reduce the number of casualties. It was made for the purpose.

[0005]

In order to solve the above-mentioned problems, the invention of claim 1 encloses a transmitting circuit for transmitting a rescue signal in the bedding, and the starting means of the transmitting circuit is provided in the bedding. It is arranged at a plurality of places, and the antenna of the transmitting circuit is arranged along the peripheral portion of the bedding so that the rescue signal is transmitted regardless of which activation means is activated.

According to the second aspect of the present invention, the starting means is a liquid injection type battery in which a brittle electrolytic solution enclosing device is included, and an electromotive force is generated by destroying the electrolytic solution enclosing device, and a rescue signal is generated. It is configured to be transmitted.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a rescue signal transmitting device according to the present invention will be specifically described below with reference to the drawings. In FIG. 1 and FIG. 2, reference numeral 1 is a bedding as a bedding, and the transmitting circuits 2, 2, 2, 2 are included in the cotton at the four corners thereof. Each transmitting circuit 2 has an antenna 3
Is connected. These antennas 3 are arranged in a loop along the periphery of the futon 1.

As shown in FIG. 3, the structure of each transmitting circuit 2 is for transmitting a rescue signal at the 426 MHz band allocated for a low power security system, or at a frequency designated by the local government for a rescue signal. Electronic circuit 21
And a liquid injection type battery 4 and a magnetic switch 5.
The antenna 3 is connected to the antenna terminal of the electronic circuit 21.

As shown in FIG. 4, the liquid injection type battery 4 comprises a container 41 made of a soft polymer resin such as polypropylene having excellent insulating properties and chemical resistance, a zinc electrode 42 and a copper electrode 43. Are fixed facing each other, a brittle thin glass electrolyte enclosure 44 is enclosed near the center of the hollow portion of the container 41, and the space around it is filled with glass fibers.

When this injection type battery 4 is strongly pinched from the outside, the container 41 is deformed and the electrolytic solution enclosure 44 inside is destroyed,
The electrolyte inside penetrates into the gap between the glass fibers,
It acts between 2 and 43 to generate electromotive force. Electrolyte enclosure 4
No electromotive force is generated unless the 4 is destroyed, and there is no deterioration such as self-discharge. An example of such a liquid-filled battery 4 is disclosed in, for example, Japanese Patent Publication No. 5-63904.

The injection of the rescue signal is started by pinching the liquid injection type battery 4 and destroying the electrolyte enclosure 44 inside. Since the liquid-filled type batteries 4 which also serve as the starting means are arranged at the four corners of the futon 1 in this way, the liquid-filled type batteries 4 can be used in any situation
Since it is possible to pick any one of the four liquid injection type batteries 4, the rescue signal can be reliably transmitted.

In FIGS. 1 and 2, 6 is a magnet piece,
When you close the futon so that it approaches each transmitter circuit 2,
They are located at one-third and two-thirds of the long side of the futon 1. The magnetic switch 5 is a magnetic sensitive switch such as a reed switch configured to be turned off when the magnet piece 6 is approaching. For example, as shown in FIG. 5, the first electrode 51 made of a magnetic material is used. And a second electrode made of a non-magnetic material
52 is a magnetic switch in which a suction piece 53 made of a magnetic material is arranged. The first electrode 51 is biased toward the second electrode 52 side, and in a normal state, the first electrode 51 and the second electrode 52 are
And are in contact with each other and are in a conductive state. However, when the futon 1 is folded and the magnet piece 6 approaches the magnetic switch 5, the magnetic field generated by the magnet piece 6 magnetizes the first electrode 51 made of a magnetic material and the attraction piece 53. Attract each other, and the first electrode 51 separates from the second electrode 52 and becomes non-conductive.

Therefore, if the futon 1 is not folded and is in a sleeping state, the rescue signal is prevented from being transmitted even if the liquid injection type battery 4 is operated for some reason. Further, in the folded state, even if the liquid injection battery 4 is activated in an earthquake, the rescue signal is not transmitted because the user is not sleeping.
Further, as shown in FIG. 6, at the edge of the futon, the operation culls 61 and 62 are connected so as to be bent when the futon is folded, and both the operation culms 61 and 62 are provided at the connecting portion. A switch 63 including a pair of electrodes that are turned off when they are bent may be provided.

Further, it is provided with one transmitting circuit, one antenna and one battery, only the switches are provided at the four corners of the futon, and when any one of the switches is operated, a rescue signal is transmitted. May be.

Further, the rescue signal transmitting device may be incorporated in the pillow. As shown in FIG. 7A, the pillow 7 includes the distress signal transmitter 72, and the ribbon 75 for starting the air battery built in the distress signal transmitter 72 is taken out from the hole of the pillow cover. Keep it. As shown in FIG. 7B, the air battery 71
The rescue signal transmitting device 72 containing the above is packaged in a vacuum state in a vacuum pack container 73 and sewn to the pillow cover 74. The ribbon 75 is adhered to the surface of the vacuum pack container 73.

Normally, the air battery 71 does not operate due to the vacuum state, and therefore no rescue signal is transmitted. However, when the ribbon 75 is pulled, the vacuum pack container 73 is broken and air flows into the inside. Therefore, the air battery 71 generates an electromotive force and the rescue signal is transmitted. It is also possible to use an injection type battery instead of the air battery.

Further, in the futon of FIG. 1, it is also possible to use an air battery instead of the liquid injection type battery. The configuration of the liquid injection battery is not limited to the above-mentioned configuration, and may be any configuration as long as an electromotive force is generated only when two or more kinds of substances are mixed or brought into contact with each other.

[0018]

[Effects of the Invention] While the bed according to the invention of claim 1 is used for sleeping, when the activating means which is the easiest to operate among the activating means arranged at a plurality of places is activated during sleep, a rescue signal is transmitted. It is possible to send a distress signal even in situations where you are unable to move due to being buried alive.

Further, since the transmitter circuit is included inside the bedding, it is protected by the bedding and is not easily damaged. Also, because the antennas are arranged along the peripheral edge of the bedding, the antennas are widely deployed during sleep and the rescue signal can be efficiently radiated, and even a small output can reach a long distance, so it can be received with low power consumption. It is possible to send a distress signal with a high probability of occurrence.

As described above, the rescue signal can be reliably transmitted in an emergency situation during sleep, and reliable rescue work can be performed as soon as possible, and the number of casualties can be reduced. According to the second aspect of the present invention, the electromotive force is generated only by destroying the electrolytic solution encapsulator contained in the liquid injection type battery, so that there is no deterioration such as self-discharge unless destroyed. In addition, since it is also a starting means to break the enclosed electrolyte encapsulator by picking up the liquid-filled battery, it is possible to reliably transmit the rescue signal simply by picking the liquid-filled battery at the four corners of the bedding. Will be possible.
