Description

Childhood shoes {child shoes}

The present invention relates to an anti-lost shoe, and more particularly, to an anti-loan shoe that generates a warning signal to the receiver of the protector so that when the distance between the child and the protector carrying the receiver is more than a certain distance, the anti-lost is not generated. will be.

In modern society, families often go out on weekends, holidays, and vacations, or they often find crowded places such as amusement parks, parks and department stores.

Parents are often embarrassed because they can't find their children in crowded places such as department stores or amusement parks.

Regarding anti-lost shoes, Korean Utility Model No. 1994-0003886 describes the contents of the anti-lost shoes sealed with details of the children wearing shoes. In addition, Korea Utility Model No. 1994-0003883 discloses the contents of shoe insoles based on the personal information of children wearing shoes, but they do not help to prevent the occurrence of missing children.

Regarding the anti-lost device, Korean Patent No. 1995-0015204 discloses a wireless anti-transmission unit, a microcomputer, and an anti-lost watch having a password function. In addition, the Republic of Korea Patent No. 1998-0160736 discloses the contents of the hand-held anti-breaker consisting of a wireless transmitter and a guardian portable wireless receiver for children. Korean Patent No. 1997-0010012 discloses a design of a portable lost alarm that can be tracked by a high frequency receiver having a necklace type or belt type high frequency transmitter and a Yagi antenna. Korean Patent Nos. 1998-014698, 1999-0035203, etc., discloses a lost beeper and portable audio including a wireless transceiver and an ultrasonic transceiver. Korean Utility Model Nos. 20-0181561 and 20-0172062 disclose information on a watch or necklace type anti-lost using a wireless pager. A common drawback of these anti-lost devices is that parents and children who go out have to carry the anti-lodge devices separately, and if they do not carry or lose the wireless transmitter, which is part of the anti-lost device, they cannot help prevent the lost. Children are inherently bothersome to lose things well and to be uncomfortable and bothersome to keep certain things. Therefore, it is very difficult for a child to always attach or carry the wireless transmitter which is a part of the anti-lost portable device while going out. Therefore, despite many patents as described above, practically no anti-loan system has been put into practice.

In particular, the antenna unit for transmitting the radio signal to the outside should have a certain length or more, in the case of the prior art has been raised as a problem caused by inconvenience, such as possession of the antenna unit longer than a certain length.

In the present invention, in order to solve the above problems, some of the children's anti-loan system should be carried or attached to a shoe with a built-in wireless transmitter and a signal transmitted from a wireless transmitter built in the shoe is a certain level or less alarm signal It relates to a shoe for preventing the loss of infants by causing the occurrence of missing. When children go out with their parents, they must wear shoes, and the children's shoes are equipped with a wireless transmission function so that the child can be prevented from running without losing any discomfort or resistance. Therefore, when children go out to crowded places with children, the alarm system of the receiver, which is carried by the guardian, automatically operates when the children are separated from the parents by more than a certain distance. The anti-loath shoes for achieving the above object is characterized by consisting of a transmitter for generating a unique radio signal within a certain distance and a receiver for generating an alarm signal when the unique radio signal generated from the transmitter is below a certain level.

Characteristic of the children's shoes having the anti-lost function according to the present invention for achieving the above object is the children's shoes with a unique radio signal transmission function and the alarm when the unique radio signal generated from the children's shoes is below a certain intensity Characterized in that it consists of a guardian receiver for generating a signal.

Children's shoes with a unique radio signal transmission function is composed of a wireless transmitter 100, an outsole (1), a midsole (2), an upper (3) and the like to generate a radio signal of a certain intensity, The transmission unit 100 includes a power supply unit 120 for supplying power, a switch unit 130 installed to turn on and off the transmitter, a password generation unit 140 for generating a unique password, and a generated unique password. A modulator 150 for modulating the signal, an oscillator 160 for amplifying and transmitting a modulation frequency transmitted from the modulator at regular intervals, an antenna unit 180 for transmitting a signal to the outside, an oscillator 160 and an antenna unit ( Characterized in that consisting of a connection terminal groove 170 for connecting 180. In particular, the antenna unit 180 for transmitting a radio signal to the outside should have a certain length or more, and in the case of the prior art, when the antenna is longer than a certain length, it is inconvenient to carry. In order to solve the problems raised as described above, in the present invention, the antenna unit 170 is installed in the length direction of the midsole inside the shoe midsole 2, and the child wearing the shoes does not feel any discomfort at all, and has sufficient strength. The conventional problem is solved by allowing the wireless signal to be transmitted to the outside.

Guardian receiver 200 having a radio frequency reception function of the natural frequency generated in the children's shoes, the switch unit 210 is installed to turn on and off the receiver, the power supply unit 220 for supplying power and The antenna 230 for receiving the radio signal, the receiver 240 for receiving the radio signal from the antenna, the demodulator 250 for demodulating the received radio signal, and the demodulated radio signal are compared with the stored unique code. The password comparison unit 260 and an alarm generator 270 for generating an alarm signal when the compared password does not match the stored password or is below a certain strength.

By operating the switch unit 130 in the configuration as described above to supply power to the wireless transmitter 100 in the children's shoes, and transmits the unique radio signal at regular intervals, the receiver receiver 200 in the transmitter unit If the radio signal transmitted from the radio frequency does not match with the natural frequency stored in the receiver, or if the reception intensity is below a certain level, an alarm is generated.

In other words, if a child wearing anti-logging shoes with a built-in wireless transmission function moves away from the guardian by a certain distance, an alarm is triggered from the receiver of the guardian and the guardian recognizes that the child accompanied by the child is out of a certain distance. It is possible to find children immediately and prevent the occurrence of missing children.

According to the present invention, a receiver carried by a guardian with a child in a crowded department store or an amusement park detects a radio signal that is continuously generated at regular intervals in a shoe worn by the child, and generates an alarm when the child is separated by a certain distance or more. The guardian immediately recognizes that the guardian is more than a certain distance away from the guardian, and can prevent the occurrence of a loss. In particular, since children do not have to carry a separate wireless transmitter other than the shoes they normally wear, there is an effect that can be prevented from occurring by default, without the problem caused by children do not have a wireless transmitter.
