Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weak current generator utilizing human power and a product to which the weak current generator is applied.

[0002]

2. Description of the Related Art In the past, it seems that there was no similar product.

[0003]

In many cases, human beings unconsciously dispose of energy generated by the human body during daily routine exercise. For example, in the walking exercise, the heel is landed on the ground every time the number of steps is advanced,
At this time, it may be possible to generate a weak current using the pressure on the heel.

[0004]

In order to achieve the above object, the present invention firstly devises a mechanism for generating a weak current by utilizing human force such as pressure on the heel, and secondly, By applying it, we devised two concrete products.

First, the structure of the generator is as follows.
Two thin plate type magnets (N pole and S pole) having a thickness of about 0.5 to 1 mm are faced to each other, and a conducting wire coil having several turns is sandwiched between them, and the conducting wire is extended from both ends to form a closed circuit. By doing this, due to changes in the magnet spacing due to human-power compression,
An electromagnetic induction action causes an induction current to flow in the coil, which guides the current to the circuit, enabling a weak current to be generated in the circuit. Furthermore, by inserting a diode in the circuit, rectification is performed, and a DC intermittent current is obtained.

Further, an elastic body (or a small spring) is sandwiched between the two magnets to maintain a space between them, so that a force repulsive to the compressive force is generated. Prevents adsorption. The maximum distance between magnets is 3 mm.

The whole is a flat type including a magnet and a circuit, and its thickness is within 5 mm.

Next, as a product to which the above is applied, a simple counter (adder) used in a calculator or the like in the power generation circuit.
By installing and installing it on the heel of the shoe, it is possible to easily measure the number of steps used by the shoe for each foot.

Further, by installing the above-mentioned power generation circuit on the heel portion of the shoe and combining it with a light emitting diode incorporated in a specific portion of the shoe surface, that portion can emit light each time it walks.

[0010]

By changing the strength of the magnet and the number of turns of the coil which constitute the generator, weak currents of various sizes can be easily taken out.

[0011]

Example: For example, the size of the generator is the size of the magnet: a circle with a diameter of 1 cm, the thickness of the magnet: 1 mm, the distance between the magnets: 2 mm, and the number of turns of the coil: 10
If the circuit size is a rectangle with a side of 2 cm and the total thickness is 4 mm, the purpose can be achieved.

[0012]

Since the present invention is constructed as described above, it has the following effects.

Since this generator has a very simple structure and a very small size, it can be applied in many cases where a weak current is required.

By incorporating the step count measuring device for shoes, the degree of use can be easily measured for each foot unit, which contributes to the management of shoes. Also, by clearing and resetting the counter at the beginning of walking exercise, it works like a pedometer and promotes walking and health.

By incorporating the light emitting device of the shoe, the target portion of the shoe can be made to emit light every time it walks, which contributes to safety such as walking at night.
