Description

  In order to create a safe and comfortable space that pedestrians can use with peace of mind, including the elderly and disabled people with limited mobility, the present invention makes information on canes used by the elderly and disabled, The present invention relates to a walking cane or a climbing cane that supports safe and secure movement.

  The traffic barrier-free law was enforced in November 2000, and the construction of a barrier-free society has become an important issue. From those with mobility restrictions, including elderly and disabled people, the elimination of steps, etc. In addition to hardware measures, there is a strong demand for software support such as information provision.

  Voice guidance, threatening measures against thieves, guidance when lost, lighting for night movement in case of a climbing accident, charging for emergency call of mobile phone without power supply, power generation, power off function It provides a cane for safety and security so that the elderly can exercise and promote the exercise of the elderly and actively go out for walks and mountain climbing. In other words, the purpose of this is to develop an information-based walking stick (IT-stick) for promoting exercise for the elderly.

  First, the IT stick is composed of a magnet, a coil, and a capacitor. Second, the LED is embedded. Third, incorporate a small speaker. Fourth, an IC tag reader is embedded in the IT stick. Fifth, plugs and adapters are embedded in the IT stick so that the power stored in the magnet, coil and capacitor can be supplied to the mobile phone as emergency power.

  For the power generation function, there is a built-in magnet suspension mechanism with a spring that keeps the simple vibration of the magnet up and down using vibration during walking, and a coil is wound around the magnet, and electromagnetic induction The power is generated by and stored in a capacitor.

    First, the IT stick is composed of a magnet, a coil, and a capacitor, and is effective in countering threats such as lighting at night and thieves using LEDs. Secondly, by incorporating a small speaker, it is possible to ask the people around for help with a loud sound in an emergency. Thirdly, by embedding an IC tag reader in an IT stick, for example, it is possible to provide voice guidance and display guidance to a climber about a flower found during mountain climbing and a famous place in the mountain. In addition, health information and information for emergency treatment can be provided even if the owner of the cane falls while walking or climbing. Fourth, the power stored in the magnet, coil and capacitor can be supplied to the mobile phone as emergency power.

Discretionary form for carrying out the invention

Hereinafter, the present invention will be described in detail based on examples.
<Example 1>

FIG. 1 shows a configuration diagram of the manufactured IT stick. When the IT stick is struck on the ground, the magnets vibrate up and down by the springs mounted on the upper and lower sides of the magnet, and an induced electromotive force is generated when the magnet reciprocates in the coil, and charges are stored in the capacitor. The prototype power generation structure is shown in FIG. In addition, four types of magnets of different materials and sizes were prepared for LED flashlights using electric double layer capacitors, and a comparative experiment of charging characteristics was conducted. The shaker was automatically shaken at 120 reciprocations / minute using the shaker of FIG. 3, and the voltage was measured every minute for up to 30 minutes. As a result, it was confirmed from FIG. 4 that the 15φ × 24 mm Nd (neodymium) system was the fastest and charging was completed in 12 minutes. This result is
φ = B × S
(Φ: magnetic flux, B: magnetic flux density, S: cross-sectional area)
As can be seen from the above equation, the result of FIG. 4 was found to be correct because of the nature of the shape effect and the higher magnetic flux density in the neodymium system than in the samarium system.
<Example 2>

In addition, as a result of applying the vibration by putting the prototype of FIG. 2 like a cane and applying vibration, a single vibration of 2 reciprocations / second was generated. Further, when the number of times the wand was struck per minute was measured by walking normally, it was 42 times / minute, which is estimated to correspond to a simple vibration of 84 reciprocations / minute. This result is 70% of the result using a shaker. Therefore, it can be estimated that it takes about 17 minutes to fully charge the capacitor mounted on the IT stick. This proved to be sufficient for practical use.
<Example 3>

With respect to the circuit configuration in the IT stick of FIG. 1, when charging a plurality of capacitors, the amount of charge to be charged is proportional to the applied voltage. Moreover, when discharging, switching to a series connection realized high efficiency discharge and quick charge. A device that can be switched to a parallel circuit at the time of charging and a series circuit at the time of discharging so as to fit in the IT stick to satisfy the above two conditions was produced. A parallel circuit when moving normally, and a system that switches to a serial circuit at the same time as pressing the switch when using the function of the IT stick, realizes power generation by vibration and mobile phone when walking in a place without power supply such as when climbing The emergency charge to etc. was enabled.
<Example 4>

For the lighting function, in order to satisfy lighting in the dark (mainly at night) and flashing of the LED against thieves, etc., white LEDs connected in parallel (9 × 3 parallel LEDs in the embodiment) ) Was used. It can be used for a long time for lighting in dark places, and for flash lighting against thieves, etc., high power lighting for intimidation is done by rapid discharge using an electric double layer capacitor so that large power can be applied to the LED at once. It was realized.
<Example 5>

A small speaker is built in so that voice guidance can be performed by reading an IC tag using an IC tag reader mounted on an IT stick. For this purpose, a system with a switch configuration in which charges are discharged from a capacitor when an IC tag is read by an IC tag reader is used. In addition, an amplifier that makes an alarm sound at a high volume is built into the IT stick to inform the surrounding people of the threat of the high volume sound from a gangster. table. 1 shows a comparison of IC tag reader / writers. The electromagnetic induction method was used as the most promising method for building into the IT stick considering the communication distance and size with the tag.
<Example 6>

FIG. 5 shows a circuit diagram of a prototype IT stick. The switch is composed of two changeover switches so that the threat of sound from the speaker and the threat of high-intensity illumination by LEDs can be achieved by rapid discharge from the capacitors. In addition, an interface such as an adapter or a plug that can generate power in the circuit built in the walking cane or climbing cane with a magnet, a coil, and a capacitor and supply the accumulated power in the capacitor to the mobile phone as emergency power. An IT stick equipped with a mobile phone was also manufactured, and the function of charging a mobile phone could be confirmed.
<Example 7>

  An IT walking stick in which the cane of Examples 1 to 6 has a telescopic structure was also made as a climbing cane. In this case, the expansion / contraction portion is structured such that the power generation portion, the charging portion, the illumination portion, the speaker portion, the electric circuit main body portion, and the IC tag mounting portion of Examples 1 to 6 do not overlap. That is, the telescopic part is provided at the center of the cane, the charging part, the lighting part, the speaker part, and the electric circuit body part are provided at the upper part, and the power generation part and the IC tag mounting part are provided at the lower part. The structure is such that it is connected with a flexible, stretchable lead wire.
