Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple device for generating a low current, and a fishing lure using the same.

[0002]

Although a large number of power generation devices have been known in the prior art, all of them require a large-scale device, and there are few small-sized devices to be carried. For example, a complex power generation device is not necessarily required for applications such as blinking an LED or operating with a weak current. Therefore, a small and lightweight power generator is desired for some applications.

[0003] On the other hand, fishing lures are used as bait, but lures with a built-in light-emitting device are said to be suitable for fish having photophobic properties. As a conventionally known lure of this type, there is a lure in which a solar cell is built in as a power generation device and an LED is made to emit light once charging is completed. This device can be used for a long time if the capacity of the battery for charging is increased, but it is not appropriate as a lure because the weight is too large. On the other hand, if the battery capacity is reduced, the weight becomes lighter in comparison with this. However, since the solar battery or the charging battery itself is heavy, there is still a problem in weight. There is also a problem that nighttime use is limited to a very short time.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to disclose a light-weight and inexpensive lure utilizing the power-generating device having a simple and lightweight structure.

[0005]

According to the present invention, in order to achieve the above object, first, as a power generating device, a hollow guide, a piezoelectric element provided in at least one opening of the guide, and an inner portion of the guide are provided. And a means for taking out power from the piezoelectric element by hitting the piezoelectric element with the impacting element.
In this means, a voltage is generated when the piezoelectric element is hit by the relative motion between the impact body and the piezoelectric element.
By taking this out with a lead wire or the like, it functions as a power generator. The guide has a function of accommodating the impact body and simultaneously guiding it to the piezoelectric element. In the means using one piezoelectric element, the opening of the guide on which the piezoelectric element is not provided is closed with a lid. Also,
In the configuration in which the guide is a cylindrical body and the impact body is housed therein, the impact body can be reliably guided to the piezoelectric element. Further, even in a configuration in which the guide is formed of three or more rods and the impact body is accommodated inside the guide, the impact body can be smoothly guided to the piezoelectric element.

[0006] Next, as a circuit utilizing the power generation device,
A means was used in which a pair of light emitting diodes were connected in reverse to the power generator via lead wires to form a light emitting circuit. In this means, the light emitting diodes alternately flash in accordance with the output waveform of the power generator.

Further, in the case of a lure, a power generating device includes a hollow guide, a piezoelectric element provided in at least one opening of the guide, and an impact body rotatably accommodated in the guide. A device and a light emitting circuit in which a pair of light emitting diodes are connected to the power generating device in opposite directions via lead wires are incorporated in the lure main body, and at least the light emitting diodes are provided so as to be visible from the outside. I decided to. According to this means, if the lure is pulled in a line during lure fishing, the lure swings, but in response to this swing, the impact body strikes the piezoelectric element, and the light emitting circuit is driven by the power. , Flashing lure. Further, in the means in which the power generator is provided at a position close to the tail and horizontally horizontal to the lure main body, since the movement is large, the impact energy is large and the light emission is strong.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, among preferred embodiments of the present invention, a power generator will be described first with reference to the accompanying drawings. FIG. 1 is a perspective view showing the entire apparatus.
Reference numeral 1 denotes a piezoelectric element, 2 denotes a base thereof, 3 denotes an inner diameter larger than that of the piezoelectric element 1, and a cylindrical cylindrical body standing upright from the base 2, and 4 denotes a cylindrical body sealed inside the cylindrical body 3. An impact body that freely rolls in the length direction of the body 3. Although another piezoelectric element may be provided symmetrically on the side opposite to the piezoelectric element 1 with respect to the cylindrical body 3, this may be omitted and the cylindrical body 3 may be closed by the lid 5. The impact body 4 is a sphere in the present embodiment, but is not limited to this as long as it can freely move inside the cylindrical body 3, and may be a polyhedron or an aspherical body. However, not only a cylinder but also a polyhedron can be adopted. Although omitted in the figure, the piezoelectric element 1
Is connected to a pair of lead wires. By keeping the inner diameter of the cylindrical body 3 and the outer shape of the impact body 4 as close as possible, the position at which the impact body 4 strikes the piezoelectric element 1 is unified, so that the center of the piezoelectric element 1 can be matched to this position. If this is the case, the power generation efficiency will be higher. Although a single impact body is used in the present embodiment, it is needless to say that a plurality of impact bodies can be accommodated.

In the power generator having the above structure, if kinetic energy is given to the cylindrical body 3 in the longitudinal direction, the impact body 4 collides with the piezoelectric element 1 in the relative motion with the impact body 4, and the collision energy Generates electric power by deforming the piezoelectric element 1. If this electric power is taken out by a lead wire, electric energy can be used. The magnitude of the energy depends on the relative momentum and the impact body 4.
Of course depends on the mass of In the configuration in which the piezoelectric elements 1 are provided on both sides of the cylindrical body 3, double electric energy can be taken out by one reciprocal relative movement, and efficiency can be improved. In the present embodiment, a case where a cylindrical tubular body is used as a guide is shown. Alternatively, three or more rods may be arranged in parallel, and an impact body may be accommodated inside. In this case, since the weight of the guide can be reduced, a light-weight power generation device can be provided.

Next, FIG. 2 shows a light emitting circuit using the power generation device of FIG. This light emitting circuit is built in the lure of the present invention. In the figure, reference numeral 10 denotes a piezoelectric element, and 11.1
2 is a light emitting diode, respectively, and the light emitting diodes 11 and 12 are connected in opposite directions. Since the piezoelectric element 10 functions as an AC power supply, by providing a pair of light emitting diodes in a reversed relationship, the light emitting diodes can be turned on and off efficiently and the range of use can be widened. FIG. 3 shows a modification of the light emitting circuit of FIG.
0b is shown. In the case of this circuit, the pair of piezoelectric elements 10a and 10b
-Since 12 will be driven, two light emitting diodes can be made to blink more efficiently. FIG. 4 further shows a modification of the light emitting circuit,
Thus, the AC generated in each of the piezoelectric elements 10a and 10b is rectified. By incorporating any of these circuits into a lure, a light emitting lure is formed. It is to be noted that a low-current light emitting device such as a neon tube may be freely used instead of the light emitting diode, and the light emitting diode is not limited to the light emitting diode.

FIG. 5 is a perspective plan view of a lure incorporating the power generation device and the light emitting circuit of the present invention, and FIG. 6 is a perspective side view of the same. In the figure, 20 is a lure body made of a suitable material, 21 is a power generator, 22 is a light emitting circuit,
Reference numeral 24 denotes a light emitting diode functioning as a light emitting body. 2
5 is a fishhook, 26 is a current plate for controlling the movement of the lure in water, and when attached to the position of the head so as to face diagonally downward as shown in the figure, the lure tends to operate downward. Will have. If a lure configured in this way is used, the lure repeats a complicated operation due to the resistance of water when the line is pulled, but the impact body incorporated in the power generation device 21 according to the horizontal movement causes the piezoelectric element to move. As a result of the impact, electric power is generated, which is
2 will cause the light emitting diode to flash. Further, since the impacting body hits the piezoelectric element, a striking sound is generated. The striking sound may also attract the fish, and lure fishing can be performed more effectively.

The mounting direction and position of the power generation device with respect to the lure are not particularly limited. However, if power generation is to be performed with high efficiency, the cylindrical body is reciprocated at a location where the lure reciprocates greatly. Is more preferably provided along the direction. Since the line is usually mounted on the head side of the lure, it is better for the generator to be located closer to the tail. In the present embodiment, the power generation device is provided in the horizontal direction. However, if the lure moves vertically, the tubular body may be provided in the vertical direction. Further, for a lure that moves in a complicated manner, the guide may be formed in a curved shape instead of a straight shape. It is not always necessary to provide the rectifying plate 26, but if it is omitted, the head is cut off in a plane to increase the resistance at this portion, the movement becomes complicated, and power can be generated efficiently.

Although the power generation device of the present invention has been described as being applied to a lure in the embodiment, the application of the power generation device is not limited to this, but is widely applied as long as it can be incorporated as a low current power generation device. be able to. For example,
When mounted on children's shoes in combination with the light emitting circuit of the embodiment, light emission is repeated each time the user walks. In addition, it can be applied to a device for visually observing vibration at a specific place by light, and has a wide range of uses.

[0014]

According to the present invention, since the above-described configuration is employed, the power generation device can be made light and simple in configuration, and can be widely used for devices that affect weight. Becomes Further, as the light emitting circuit, by providing at least one piezoelectric element, a pair of light emitting bodies can be turned on and off alternately, and efficiency can be improved. Furthermore, a lure incorporating these devices can be a device that is lightweight and can withstand long-term use.
