DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to prevent the owner of a portable item from leaving the belongings or not taking care of the belongings to prevent the belongings from being stolen. The present invention relates to a device for preventing lost or stolen belongings, which can prevent misplacement or theft of belongings.

[0002]

2. Description of the Related Art In many cases, when an owner goes out with a portable item, the owner often carries something important.
For example, a handbag or accessory bag containing a wallet or a card, a briefcase carrying important documents, a travel bag during travel, and the like. Losing them will result in the loss of valuable property and will hinder the achievement of the purpose of going out.

[0003] However, when going out, in a busy place, a vehicle such as a public transportation such as a train, a retail store such as a department store or a supermarket, or the like, these important belongings may be misplaced or stolen. There are often. Owners must always prevent this at their own risk. To do so, we need to pay constant attention to the existence of belongings.

However, in modern society, owners are always exposed to many external stimuli, and it is not always possible to pay attention only to the items carried. For this reason, attention to the existence of the belongings often diminishes, and in such a situation, the above-mentioned misplacement or theft occurs.

Heretofore, in order to prevent such misplaced items from being left behind or stolen, it has been the most effective means to connect the items to the owner's belt or the like with a string or the like. Recently, GPS technology using artificial satellites and technology for confirming the location of objects and persons using mobile communication terminals such as PHS have been developed.

[0006]

However, the means for connecting a portable object to the body with a string is a risk of injury when the owner's behavior is restricted by the string, and in the case of an aggressive theft such as snatching. Sex is also pointed out. Also, GPS
The location of objects using technology and mobile communication terminals is
The reality is that the mechanism is large and it is difficult to spread in price and performance.

The present invention has been made in view of the above-mentioned problems of the conventional portable article loss and theft prevention means, and provides a portable article loss and theft prevention apparatus that can easily and reliably prevent misplacement or theft by using a small device. It is intended to do so.

[0008]

According to the present invention, in order to achieve the above-mentioned object, a small transmitter 4 for emitting a weak radio wave is provided.
In combination with the receiver / alarm 3 which receives the radio wave emitted from the transmitter 4, determines whether or not the radio wave is received or the strength of the radio wave, and issues an alarm when the transmitter 4 is separated by a predetermined distance or more. Is used. Transmitter 4 to carry 2
Is attached, and the owner 1 of the portable article 2 has the receiving alarm 1, so that when the portable article 2 is separated from the owner 1 by a certain distance, the receiving alarm 3 issues an alarm and the owner 1
Warning.

That is, the portable item loss / theft prevention device according to the present invention includes a transmitter 4 attached to the portable item 2 for the purpose of preventing the portable item 2 carried by the owner 1 from being lost or stolen. , Which is combined with a reception alarm 3 which is carried by the owner 1 of the portable item 2 and receives radio waves emitted from the transmitter 4 and issues an alarm when the transmitter 4 is separated by a predetermined distance. .

[0010] In such a device for preventing lost or stolen belongings,
When the owner 1 of the carry-on article 2 tries to leave the carry-on article 2 or is taken away by theft, the reception alarm 3 and the transmitter 4 are separated by a predetermined distance. 3 issues an alarm and informs owner 1 of the condition. For this reason, the owner 1 can avoid the risk of losing the belongings 2.

[0011] The portable article loss and theft prevention apparatus is simple because it can be constituted only by the reception alarm 3 and the transmitter 4. Particularly, in recent years, since a small communication device has been realized, a small reception alarm 3 and a transmitter 4 can be used, and the transmitter 4 can be attached or stored in the portable object 2 without a sense of incongruity, or the reception alarm can be used. 3 can be carried without discomfort.

The radio wave transmitted from the transmitter 4 contains the individual recognition information, and the reception alarm 3 checks the individual recognition information, and when the individual recognition information included in the radio wave matches the predetermined information. Does not trigger an alarm. By doing so, the reception alarm 3 can issue an alarm only when necessary without causing malfunction due to radio waves flying into the city, and the reliability of the alarm can be increased.

Further, the reception alarm device 3 emits a radio wave A,
The transmitter 4 operates by receiving the radio wave A, and the reception alarm device 3 emits the radio wave B to be received. By doing so, even when the radio wave emitted from the reception alarm device 3 cannot be received by the transmitter 4, the reception alarm device 3 issues an alarm, and double security is ensured.

[0014]

Embodiments of the present invention will now be described specifically and in detail with reference to the drawings.
As shown in FIG. 1, the portable item loss / theft prevention device according to the present invention includes a reception alarm 3 carried by the owner 1 of the portable item 2,
And a transmitter 4 housed or attached to the portable object 2.

The reception alarm 3 carried by the owner 1 of the portable object 2 emits a radio wave A. The radio wave A provides a condition for the operation of the transmitter 4 stored or attached to the portable object 2. The transmitter 4 operates by receiving the radio wave A and emits the radio wave B. This radio wave B is received by the reception alarm 3. The radio wave B includes the individual recognition information, and the reception alarm device 3 compares the individual recognition information recorded therein with the individual recognition information included in the received radio wave B, and only when they match with each other. The information of the radio wave B is processed.

When the transmitter 4 is separated from the transmitter 4 by a predetermined distance, the receiver 3 detects the radio wave B received by the receiver 3 and issues an alarm. Specifically, when the intensity of the radio wave B received by the reception alarm device 3 becomes smaller than a certain threshold value, or when the reception alarm device 3 cannot receive the radio wave B, an alarm is issued. As a result, theft of the portable object 2 such as being left behind or being left behind is prevented. Here, the warning means not only a warning by a sound such as a bell, a buzzer, and a warning sound, but also any warning means that can be detected by a person, such as vibration.

As shown in FIG. 2, the receiving alarm 3 is a small-sized one which can be easily carried by the owner 1 while wearing it.
It has an antenna on the surface and has a receiver, signal processor and sounder incorporated inside. The reception alarm 3 can be incorporated in a thing worn by a person, such as a wristwatch. On the other hand, the transmitter 4 is a card-shaped one that can be stored in a wallet or a wallet without any incongruity, has an antenna on the surface, and has an integrated function having a receiver, a signal processor, a transmitter, and the like inside. The circuit is incorporated.

FIG. 3 is a block diagram showing a processing system for radio waves and signals of the reception alarm device 3 and the transmitter 4. The reception alarm device 3 includes a transmission unit 11 and emits a radio wave A from an antenna. The antenna of the receiving alarm 3 is omnidirectional and emits a radio wave A with an equal output in all directions.

The transmitter 4 includes a receiving unit 12, receives the radio wave A through an antenna, and outputs an operation signal to the transmitting unit 13 to operate the transmitting unit 13. Transmitter 1
3 emits a radio wave B of a predetermined frequency including the individual recognition information. The antenna of the transmitter 4 is also omnidirectional and emits a radio wave B with uniform output in all directions.

The receiving alarm device 3 has a receiving section 5 for receiving the radio wave B. This radio wave B is amplified by the amplifier 6 and then processed by the processing unit 7. First, a storage unit 1 such as a ROM
0 is compared with the individual recognition information stored in advance in the radio wave B, and if they match, the radio wave B
Check the strength of the. When the signal strength of the amplified radio wave B reaches a predetermined threshold, no sound signal is sent to the sounding body 9. On the other hand, when the signal strength of the amplified radio wave B does not reach the predetermined threshold, the sounding body 9
A sounding signal is sent to the sounding device 9 and the sounding body 9 is operated to generate an alarm. This processing unit 7 is adjusted by the controller 8. For example, the controller 8 controls the threshold value of the signal strength of the radio wave B and the volume control of the sounding body 9.

The controller 8 controls the radio wave B
By adjusting the threshold value of the signal strength, the distance between the receiving alarm device 3 that issues an alarm and the receiving section 5 can be adjusted. For example, in the case of a wallet or a handbag, the warning is frequently issued by shortening the distance at which the warning is issued to 80 to 100 cm, and by making the distance at which the warning is issued relatively large, such as a large travel bag, to 100 to 150 cm. At the same time as eliminating the hassle of being emitted, it is possible to reliably prevent misplacement or theft by setting the optimum distance.

FIG. 4 shows a portable item loss / theft prevention apparatus according to another embodiment of the present invention, which is more simplified. In the portable item loss and theft prevention device, the transmitter 4 always operates while the switch is turned on. Therefore, the reception alarm device 3 does not need to output the radio wave A for operating the transmitter 4 and does not use the radio wave A from the transmitter 4 as a condition for operation. Others are the same as those shown in FIG.

[0023]

As described above, according to the present invention, a small-sized device such as the reception alarm 3 and the transmitter 4 can realize a device for preventing the loss or theft of the carried item. Can be attached or stored,
The owner 1 of the portable item 2 carries the reception alarm 3 without burden, and the object of the loss and theft prevention of the portable item can be achieved.
