Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light emitting lure that emits light from a lure fish body.
[0002]
[Prior art]
One of the factors that influence the fishing result in lure fishing is whether or not the lure is easily caught by the vision of the target fish, that is, whether or not the lure can attract the attention of the target fish. There's a problem. Therefore, the lure has been devised in various ways to visually attract the attention of the fish. One of them is to incorporate a light source into the lure fish body so that the lure itself emits light (hereinafter "light emitting lure"). There is).
[0003]
Although the appearance of the light emitting lure varies depending on the target fish, a light emitting diode is generally used as a light source in the light emitting lure, and a light source such as a lithium battery is used as a light source for emitting the light emitting diode. (Primary batteries) are used (for example, see Patent Literature 1, Patent Literature 2, and Patent Literature 3). Further, as such a power source, there is a type in which a solar battery is combined with a secondary battery such as a nickel-metal hydride battery, and the power generated by the solar battery is used by charging the secondary battery (for example, see Patent Document 4). .
[0004]
The light emitting mode of the light emitting diode in the light emitting lure is blinking light emission by electronic circuit technology or constant light emission (lighting). For turning on / off the light emitting diode, a method of disassembling the lure and removing the battery or a manual method such as inserting the battery in the same place in the opposite direction is adopted.

[0006]
[Problems to be solved by the invention]
However, when a primary battery such as a lithium battery is used, there is a complication that the lure must be disassembled on site to turn on / off the light emitting diode. In addition, it is necessary to always have a spare battery in preparation for running out of batteries.For example, if you forget to prepare a spare battery or if you use up this spare battery, catch more. There is a problem that can not be done.
[0007]
In addition, since the light emitting diode has high luminance but low illuminance, if the light emitting diode is constantly illuminated, the visual appeal effect on the fish is reduced, and there is a problem that it is difficult to obtain expected fishing results. In the case where the light emitting diode is driven to blink by circuit technology, there is an unnaturalness in which the light emitting diode blinks irrespective of the movement of the lure, and there is a problem that it is difficult to obtain expected results.
[0008]
Furthermore, in a lure equipped with a power supply that combines a solar cell and a secondary battery, there is no need to replace the battery, so there is no need to disassemble the lure. Except for a rare environment such as the vicinity, power generation by a solar cell cannot be expected in water. Therefore, it is necessary to charge the lure to sunlight sufficiently to operate the solar battery and charge the secondary battery before the start of fishing.
[0009]
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a light emitting lure that does not require a battery, in other words, does not require battery replacement or charging operation. Another object of the present invention is to provide a light emitting lure capable of natural flashing light emission in accordance with the movement of the lure.
[0010]

A power supply unit incorporated in the lure fish body and supplying power for causing the light emitting element to emit light to the light emitting element,
With
The power supply means,

A piezoelectric element that generates electric power by bending by an acting force;
Light emission control means for sending power generated by bending of the piezoelectric element to the light emitting element and controlling light emission of the light emitting element,
A light emitting lure is provided, comprising:
[0011]
Further, according to the present invention, a lure fish body having a cavity therein,
A light-emitting element incorporated into the lure fish body for external observation,
A power supply unit incorporated in the lure fish body and supplying power for causing the light emitting element to emit light to the light emitting element,
With
The power supply means,
Individually, one end in the longitudinal direction is fixed, and a weight is attached to the other end, a plurality of piezoelectric elements that are flexibly arranged in a different bending direction in the cavity of the lure fish body,
Light emission control means for sending power generated by bending of the piezoelectric element to the light emitting element and controlling light emission of the light emitting element,
Has,
When an external force acts on the lure fish body, at least one of the plurality of piezoelectric elements bends and generates power by a force acting on the weight attached to each of the plurality of piezoelectric elements. A light emitting lure is provided.
[0012]
In this light emitting lure, one piezoelectric element (a total of three piezoelectric elements) can be flexibly bent in three directions (that is, the length direction, the thickness direction, and the height direction) orthogonal to each other in the lure fish body. By arranging, any of the piezoelectric elements can generate power, regardless of the direction in which the lure fish receives a force.
[0013]
In these light emitting lures according to the present invention, a primary battery, a solar battery, and a secondary battery are not used because the light emitting device emits light using electric power generated by a piezoelectric element built in the lure fish body. Thus, there is no need to perform a battery replacement operation or a charging operation. In addition, for example, when the angler moves the lure through the string by operating the rod, or when the lure fish moves due to waves, that is, when an external force is applied to the lure, the piezoelectric element built in the lure fish Is bent to generate electric power, and the electric power causes the light emitting element to emit light. Therefore, natural light emission in accordance with the movement of the lure becomes possible.
[0014]
Light emission control means for controlling the light emission of the light emitting element, a rectifier circuit for rectifying the current generated by the piezoelectric element, and of the power rectified by the rectifier circuit, sends the power required for light emission of the light emitting element to the light emitting element in real time, A charge / discharge circuit for temporarily storing surplus power in a capacitor and adjusting the light emission time of the light emitting element by sending power from the capacitor to the light emitting element. Thus, for example, even when the lure is moving to such an extent that the piezoelectric element is not bent, the light emitting element can emit light using the power stored in the capacitor.
[0015]
In the light emitting lure of the present invention, the lure fish body can be made of a hard material. Therefore, even in a light emitting lure targeting a large migratory fish or the like, sufficient strength can be ensured. Examples of the piezoelectric element that causes bending displacement include a bimorph element, a unimorph element, a monomorph element, and a multimorph element. In addition, a light emitting diode is suitably used as the light emitting element. For example, the light emitting diode can be incorporated in both eyes of a lure fish body.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side view of the light emitting lure 10, and FIGS. 2 and 3 are schematic sectional views thereof. Here, in order to facilitate the following description, in the light emitting lure 10, the orthogonal coordinate axes are the X axis, the longitudinal axis from the head to the caudal fin is the X axis, the directional axis from the abdomen to the back is the Z axis, and the chest is The piercing direction axis is defined as the Y axis.
[0017]
The light-emitting lure 10 has a pseudo fish-shaped lure fish body 11 having a cavity 16 inside, a light-emitting element 12 attached to the lure fish body 11 so as to be externally observable, and a light-emitting lure 10 provided in the cavity 16 for causing the light-emitting element 12 to emit light. Supplied power supply means 13. The lure fish body 11 is made of, for example, various hard materials such as a metal material such as lead or zinc die-cast, an engineering plastic material such as an epoxy resin or an ABS resin, a ceramic material, a porcelain material, a glass material, and a fiber-reinforced plastic material. . Various decorations (for example, scale members) can be attached to the surface of the lure fish body 11, and various patterns (for example, stripes and scales) can be drawn.
[0018]
As shown in FIG. 3, the lure fish body 11 is integrated by bonding the lure fish body members 11a and 11b, which are almost equally divided on the ZX plane, using, for example, an adhesive. An adhesive layer is not shown in FIG. 3), and this adhesive layer plays a role of a sealing material for preventing water from entering the cavity 16. The lure fish members 11a and 11b may be integrated with each other by screwing or the like. In this case, for example, a seal ring is arranged along the outer shell to prevent water from entering the hollow portion 16. Is preferred.
[0019]
Eye fittings 14a, 14b, and 14c are buried near the mouth, abdomen, and tail of the lure fish member 11a, and hooks (needle) 15a and 15b are attached to the eye fittings 14b and 14c, respectively. A thread is attached to the eye fitting 14a. The fixing positions of the eye fittings 14b and 14c for attaching the hooks 15a and 15b are not limited to the positions shown in FIGS. The eye fittings 14a to 14c have a substantially T-shaped shape, and have a structure that is hard to come off from the lure fish body member 11a even when a large force is applied.
[0020]
As the light emitting element 12, a light emitting diode is preferably used. There is no limitation on the emission color of the light emitting diode. In the light emitting lure 10, the light emitting element 12 is incorporated in the lure fish body 11 as both eyes of the lure fish body 11, but the light emitting element 12 can be provided in other parts.
[0021]
The power supply unit 13 includes a bimorph element 17 that is one of the bending displacement type piezoelectric elements, and a light emission control circuit 18 that sends power generated by bending of the bimorph element 17 to the light emitting element 12 and controls light emission of the light emitting element 12. are doing. The circuit board of the light emission control circuit 18 is fixed to the cavity 16. The bimorph element 17 has a rectangular shape, a thin thickness, and piezoelectric ceramic plates 21a and 21b having electrodes (not shown) formed on the front and back surfaces, respectively, such as a metal thin plate, an FRP (fiber reinforced plastic) thin plate, and a resin sheet. It has a structure attached to the front and back surfaces of the reinforcing plate 22.
[0022]
The bimorph element 17 has an end in the longitudinal direction (X direction) held by a fixing jig 24 fixed to the cavity 16, and the main surface thereof is oriented in the Z direction. And the other end in the longitudinal direction is a free end. Therefore, the bimorph element 17 can be bent in the Z direction. At the free end of the bimorph element 17, a weight 23 made of a metal material having a large specific gravity, such as lead, is attached, and the angler operates the rod to move the light emitting lure 10 through the line. When a force in the Z direction is applied to the light emitting lure 10 due to, for example, the light emitting lure 10 being shaken by a wave or the like, a force in the Z direction is also applied to the weight 23. As a result, the bimorph element 17 bends largely, subsequently vibrates freely, and eventually attenuates and stops. Since a voltage is generated in the piezoelectric ceramic plates 21a and 21b by the piezoelectric effect at the time of bending, the electric power generated in the piezoelectric ceramic plates 21a and 21b is sent to the light emitting element 12 through the light emission control circuit 18 to cause the light emitting element 12 to emit light.
[0023]
FIG. 4 is an explanatory diagram showing the configuration of the light emission control circuit 18. The light emission control circuit 18 includes a rectifier circuit 31 that rectifies the current generated by the bimorph element 17, and a charge / discharge circuit that stores a part of the power rectified by the rectifier circuit 31 and supplies the stored power to the light emitting element 12. 32. The rectifier circuit 31 has a configuration in which a diode 33 is connected in a Wheatstone bridge type. The charge / discharge circuit 32 includes a capacitor 34 for storing / discharging power, and a resistor 35 connected in series with the capacitor 34.
[0024]
According to the light emission control circuit 18 described above, of the power rectified by the rectification circuit 31, the power required for light emission of the light emitting element 12 is sent to the light emitting element 12 in real time to cause the light emitting element 12 to emit light. Further, since the remaining power (that is, surplus power) is temporarily stored in the capacitor 34, even if the bimorph element 17 stops generating power, the power is transmitted from the capacitor 34 to the light emitting element 12 so that the light emitting element 12 The light emission time can be lengthened. The light emission time of the light emitting element 12 is determined by the resistance value of the resistance element 35.
[0025]
As described above, the light emitting lure 10 bends the bimorph element 17 by the force applied to the light emitting lure 10 and obtains the electric power necessary for the light emitting element 12 to emit light, and thus does not require a battery. Therefore, there is no need to replace or charge the battery, and there is no need to prepare a spare battery. In addition, since the light emitting element 12 emits light in accordance with the movement of the light emitting lure 10, the timing shift between the movement of the light emitting lure and the light emission of the light emitting element, which is a problem in the conventional light emitting lure, and the regular light emitting element Unnaturalness such as light emission is eliminated, and the effect of collecting fish can be enhanced.
[0026]
Next, another embodiment of the light emitting lure according to the present invention will be described. FIG. 5 is a schematic sectional view showing the structure of the light emitting lure 50. The light emitting lure 50 includes a lure fish body 51 having a hollow portion 52 therein, a light emitting element 12 attached to the lure fish body 51 so as to be externally observable, and a power supply unit provided in the hollow portion 52 for causing the light emitting element 12 to emit light. 53. FIG. 6 is an explanatory diagram schematically illustrating the configuration of the power supply unit 53 and the electrical connection between the power supply unit 53 and the light emitting element 12. FIG. 5 does not show the electrical connection between the power supply means 53 and the light emitting element 12.
[0027]
The lure fish body 51 is composed of a lure fish body member 51a and a weight member 51b attached to the abdomen of the lure fish body member 51a. For example, when a material having a low specific gravity is used for the lure fish member 51a, the weight and the weight balance of the light emitting lure 50 can be adjusted by using a material having a high specific gravity such as a lead plate as the weight member 51b. . Of course, the lure fish body member 51a may be made of a metal material or a porcelain material.
[0028]
The cavity 52 is formed in the lure fish member 51a, and the cavity 52 is isolated from the outside by bonding the weight member 51b to the lure fish member 51a. Eye fittings 54a and 54b are fixed to the mouth and caudal fin of the lure fish member 51a, respectively, so that a thread can be attached to the eye fitting 54a and a hook (not shown) can be attached to the eye fitting 54b. It has become.
[0029]
The power supply unit 53 includes three bimorph elements 57a, 57b, and 57c, and a light emission control circuit 58 that sends power generated by bending the bimorph elements 57a to 57c to the light emitting element 12 and controls light emission of the light emitting element 12. ing. Since the structures of the bimorph elements 57a to 57c are the same as those of the bimorph element 17 described above, detailed description is omitted here. Fixing jigs 55a to 55c respectively holding the bimorph elements 57a to 57c are provided at predetermined positions of the cavity 52, and the bimorph element 57a is fixed to the fixing jig 55a so that the main surface faces the X direction. The bimorph element 57b is fixed to the fixing jig 55b so that the main surface faces in the Y direction, and the bimorph element 57c is fixed to the fixing jig 55c so that the main surface faces in the Z direction.
[0030]
The bimorph element 57a can be bent in the X direction, the bimorph element 57b can be bent in the Y direction, and the bimorph element 57c can be bent in the Z direction. When the angler operates the rod to move the light emitting lure 10 through the yarn, or when the light emitting lure 10 is shaken by a wave or the like and a force is applied to the light emitting lure 10, at least one of the bimorph elements 57a to 57c is applied. One is bent by the force applied to the weight fixed to the free end thereof, and subsequently vibrates freely, and eventually attenuates and stops.
[0031]
The power generated by the bimorph element 57a is sent to the light emitting element 12 through the rectifier circuit 31a. Similarly, the electric power generated by the bimorph element 57b is sent to the light emitting element 12 through the rectifier circuit 31b, and the electric power generated by the bimorph element 57c is sent to the light emitting element 12 through the rectifier circuit 31c. By providing the rectifier circuits 31a to 31c in each of the bimorph elements 57a to 57c, for example, it is possible to prevent the negative voltage of the bimorph element 57a and the positive voltage of the bimorph element 57b from canceling each other and preventing power from being obtained. be able to.
[0032]
In the light emitting lure 10 shown in FIGS. 1 to 3, when a force is applied in the X direction or the Y direction, the bimorph element 17 is hardly bent, and therefore, the light emitting element 12 is hard to emit light. However, in the light emitting lure 50, at least one of the bimorph elements 57a to 57c bends to generate electric power no matter in which direction a force is applied, so that the light emitting element 12 can emit light. Therefore, the light emitting lure 50 can realize more natural light emission according to the movement than the light emitting lure 10.
[0033]
The embodiments of the present invention have been described above, but the present invention is not limited to such embodiments. For example, in the above description, a bimorph element is taken up as a bending displacement type piezoelectric element.However, a unimorph element configured by attaching a piezoelectric ceramic plate having electrodes formed on the front and back surfaces to one surface of a reinforcing plate, and a A monomorph element consisting only of a piezoelectric ceramic plate on which electrodes are formed, a multimorph element formed by alternately laminating piezoelectric ceramic thin plates and electrodes and connecting these electrodes every other layer, such a multimorph element on one side of a reinforcing plate Alternatively, a laminated unimorph element or a laminated bimorph element which is attached to both surfaces can be used.
[0034]
The light-emitting element 12 is not limited to a light-emitting diode, and the light-emitting element 12 does not have to be provided limited to an eye portion of a lure fish body. FIG. 7 is a schematic configuration diagram of a light emitting system 60 applicable to a light emitting lure. On one body side of the lure fish body 11, five diffusion lenses 61a to 61e (a diffusion lens is similarly arranged on the other body side (back side of the paper), but not shown) are attached for external observation. Have been. Inexpensive plastic lenses can be used as the diffusion lenses 61a to 61e. As the diffusion lenses 61a to 61e, lenses having different outer diameters and colors can be used.
[0035]
The power supply means 13 causes one light emitting diode 63 to emit light. For this reason, as compared with the case where the power supply means 13 causes the two light emitting diodes 12 to emit light as shown in FIG. 4, a larger power can be supplied to the light emitting diode 63, and thus the light emitting diode 63 emits light. A device having a higher luminance than the diode 12 can be used. The light emitting diode 63 can be disposed in a cavity 16 (not shown) formed inside the lure fish body 11.
[0036]
The light emitted from the light emitting diode 63 is transmitted to the diffusion lenses 61a to 61e by optical fibers 62a to 62e provided in the lure fish body 11, respectively. It can emit light. Plastic optical fibers can be used as the optical fibers 62a to 62e. By using such a light emitting system 60, it is possible to manufacture a light emitting lure in which the number, color, and arrangement position of the diffusion lenses are variously changed.
[0037]
As a light-emitting system adopted in the light-emitting lure according to the present invention, a light-emitting control device that arranges a plurality of light-emitting diodes having different coloring lights on a lure fish body and selects one having a predetermined light-emitting color from among them to emit light. (CPU) equipped with a lure fish body can also be used. In this case, the light emission control device is also configured to operate by the power generated by the bimorph element. Then, for example, taking the light emitting lure 50 as an example, a plurality of light emitting diodes (for example, red, yellow, and green) having different coloring light are provided for both eyes and other portions, and red light is emitted by the power of the bimorph element 57a. The light emitting diode may emit light, the yellow light emitting diode emits light by the power of the bimorph element 57b, and the green light emitting diode emits light by the electric power of the bimorph element 57c.
[0038]
In the above description, the outer shape of the light-emitting lure is a fish shape, but the outer shape of the light-emitting lure is not limited to such a form.For example, according to the prey intended for lure fishing, for example, shrimp and crab, It can be in the form of various aquatic organisms such as octopus and squid.
[0039]
【The invention's effect】
As described above, according to the light emitting lure of the present invention, it is not necessary to use a battery to cause the light emitting element to emit light by using the electric power generated by the bending displacement type piezoelectric element. Therefore, there is no need to perform complicated operations such as battery replacement and solar battery charging, and there is no need to facilitate spare batteries. In addition, since natural blinking light emission or lighting in accordance with the movement of the lure is possible, the fish collecting effect can be enhanced.
