DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 and 2, a lure V according to this embodiment is provided in a water-tight lure main body H and emits light to the outside; L, and a piezoelectric generator A connected to the rechargeable battery B. The rechargeable battery B is electrically connected to the piezoelectric generator A via a rectifier circuit S.

The lure main body H is formed of a known material and shape. The lure main body H is provided with a fishing hook 25 and a rectifying plate 26 for controlling the movement of the lure in water. When the current plate 26 is attached to the head in the illustrated example so as to face diagonally downward, the lure is controlled to operate downward. Therefore, in the case of using the lure configured as described above, each time the line is drawn, the lure repeats a complicated operation due to the resistance of water, and the piezoelectric generator A generates power by this operation, and the power is charged to the charger B. After the power is
In addition to the above, the hitting sound of the beating body described later also has a fish collecting effect in some cases, so that the fish collecting effect is greatly improved as a whole.

Further, as described above, the voltage generated by the piezoelectric generator A is rectified by the rectifier circuit S and charged in the rechargeable battery B, and the luminous body L is turned on with the charged power. In order to enable charging regardless of the polarity of the voltage generated in the piezoelectric generator A, it is desirable to use a circuit in which a bridge is combined with a diode as the rectifier circuit S. An overcharge and overdischarge prevention circuit is connected to the charging circuit of the rechargeable battery B, and the overcharge / overdischarge prevention circuit is automatically opened when the piezoelectric generator A does not generate power for a predetermined time. It is desirable.

Next, an example of the configuration of the piezoelectric generator A disposed in the lure having the above-described configuration will be sequentially described. The piezoelectric generator A1 shown in FIG. 3 is configured such that the piezoelectric ceramic plates 1 are arranged at both ends of a cylindrical container 8 having both ends closed, and the piezoelectric ceramic plates 1 generate power by hitting steel balls 4.
The cushion plate 3 is adhered to one side surface of the container 8 using an adhesive 6, and only the center of the cushion plate 3 is attached to the adhesive 5.
Is used to bond the piezoelectric ceramic plate 1. Similarly, the piezoelectric ceramics plate 1 is bonded to the other side surface of the container 8 so that both sides face each other. The protector plate 2 is fixed to the center of the facing surfaces of the two piezoelectric ceramic plates 1. Then, a pipe 7 is arranged between the two piezoelectric ceramic plates 1, and a rollable steel ball 4 is provided in the pipe 7.

The piezoelectric ceramic plate 1 is composed of two plate-like piezoelectric ceramic elements 1a and 1b of the same form (the same material, the same shape and the same thickness).
The junctions are made with the polarities of a and 1b reversed.
By joining the ceramic elements 1a and 1b of the same form, the two ceramic elements 1a and 1b vibrate flexibly around the joint surface (the part that does not expand or contract). In this case, if the ceramic element 1a on one side expands, the ceramic element 1b on the other side contracts, and the electrodes of the output voltage become in the same direction, and the two piezoelectric ceramic elements 1a and 1b are connected in series. Becomes

The piezoelectric ceramic elements 1a and 1b are
It is known as a conversion element for converting between mechanical energy and electrical energy, and many inorganic and organic materials exhibiting a piezoelectric effect are known. System (piezo
electric ceramics).

A piezoelectric ceramic element is an element in which a high direct current voltage is applied to a polycrystal to generate remanent polarization to give piezoelectricity, and the basic piezoelectric constant can be changed quite freely by the composition. The zinc-zirconate-based piezoelectric ceramic element has a wide selection range of composition ratio and additives, and is suitable for a lure as in the present invention.

By the way, when the flexural vibration is carried out around the joint surface, one of the piezoelectric ceramic elements 1a (or 1b) performs both expansion and contraction, so that the polarization is not canceled out. Power generation is performed efficiently. The electric current as the generated electric energy is the lead wire 9
Take out using.

Although two piezoelectric ceramic elements 1a and 1b are laminated here, each piezoelectric ceramic element 1a and 1b is laminated.
a (1b) can each have a laminated structure.
In this laminated structure, a plurality of thin piezoelectric ceramic plates are joined (in this case, the polarity of polarization is the same) to form one piezoelectric ceramic element 1a (or 1b). In this way, by adopting a laminated structure, for example, when joined by an adhesive having elastic characteristics, due to this elastic effect,
The bending of the ceramic plate material lacking in material strength is facilitated and the bending strength can be maintained, and the thinner the ceramic plate is, the stronger the bending becomes. Further, the outer shape of the piezoelectric ceramic plate 1 is not particularly limited, but the front shape may be a circle, an ellipse, a triangle, a square, a polygon, or the like.

The cushion plate 3 is made of a synthetic resin material, a rubber material or a sponge-like soft material. The reason why such a cushion plate 3 is used and that the piezoelectric ceramic plate 1 is fixed to the center portion of the cushion plate 3 using the adhesive 5 is that the vibration of the piezoelectric ceramic plate 1 is not attenuated. When the piezoelectric ceramics plate 1 vibrates, the member supporting the piezoelectric ceramics plate 1 becomes a factor for attenuating the vibration of the piezoelectric ceramics plate 1. In order to eliminate the damping factor, the cushioning plate 3 is used to minimize the piezoelectric ceramics plate. Leave 1 free.

By using the cushion plate 3, the natural vibration of the piezoelectric ceramic plate 1 lasts for a long time, so that the power generation efficiency is improved. The cushion material is a piezoelectric ceramic plate 1
To reduce the impact applied to The protector plate 2 is made of metal, synthetic resin, or the like, and protects the piezoelectric ceramic plate 1 from hitting the steel ball 4.

When the lure equipped with the piezoelectric generator A1 having such a configuration is pulled in water, the steel ball 4 rolls in the pipe 7 and strikes the left and right piezoelectric ceramic plates 1, and the impact due to the collision occurs. Apply energy. Then, the piezoelectric ceramic plate 1 is excited to vibrate, and repeats its expansion and contraction to generate AC electricity.

Here, as the hit body, the steel ball 4 is disposed in the pipe 7 to hit the piezoelectric ceramic plate 1, but the material and shape of the hit body are limited to steel balls. Instead of a heavy object, a heavy object such as a column or an egg may be used. In addition, not only the pipe 7, but also a form in which the hit body can move along the rail as long as the hit body can move freely. In addition, a spring material (upward or downward) is used in place of the pipe 7, one end of the spring material is fixed, and the steel ball 4 is attached to the other end. Board 1
Can be beaten.

FIG. 4 shows a charging circuit for charging the electricity generated by the piezoelectric generator A1. This charging circuit has two piezoelectric ceramic plates 1 as PZT1 and PZT2, rectifying diodes D1 to D6, and a rechargeable battery B for storing electricity. The electricity generated by PZT1 is full-wave rectified by diodes D1 to D3,
Is generated by the diodes D4 to D6. The full-wave rectified electricity is charged to the rechargeable battery B. The full-wave rectified electricity is charged to the rechargeable battery B. Then, for example, the rechargeable battery B is discharged by an automatic changeover switch (not shown) to light up a required number of light-emitting elements L composed of known low-current light-emitting elements such as light-emitting diodes or neon tubes.

FIG. 5 shows an example of a piezoelectric generator A2 using one piezoelectric ceramic plate 1. This piezoelectric generator A2
Uses a cylindrical container 12 whose both ends are closed, and a cushion member 1 is provided on an upper surface and a lower surface of a central portion of the container 12.
The piezoelectric ceramic plates 1 (1a, 1b) are fitted into the recesses of the cushion member 11 and supported. Protector plates 2 are attached to both sides of the piezoelectric ceramic plate 1. Pipes 7 are arranged on both sides of both piezoelectric ceramic plates 1, and rolling steel balls 4 are provided in these pipes 7. The material of the cushion member 11 is the same as that of the cushion plate 3, and the other members are also as described above.

When the lure equipped with the piezoelectric generator A2 is pulled in water, the steel ball 4 rolls in the pipe 7 and alternately strikes the piezoelectric ceramic plate 1, and the piezoelectric ceramic plate 1 vibrates. Are excited and the elongation and contraction are repeated to generate AC electricity.

FIG. 6 shows an example of a wind-bell type piezoelectric generator A3. In the piezoelectric generator A3, the piezoelectric ceramics plate 1 is attached to two locations (three or more locations are possible) on the inner peripheral surface of the bell-shaped container 14 so as to face each other. When mounting,
The cushion plate 3 is bonded 6 to the inner peripheral surface, and the piezoelectric ceramic plate 1 is bonded only to the central portion of the cushion plate 3 using the bonding material 5. The piezoelectric ceramic plate 1 is similarly arranged on the surface facing this, and both piezoelectric ceramic plates 1
Attach the protector plate 2 to the center of the facing surface.

Then, the steel ball 4
Is suspended from the steel ball 4. The material and the like of each member are as described above. If the piezoelectric generator A3 is floated in an environment in which it swings in water, the steel ball 4 swings and strikes the piezoelectric ceramic plate 1, and the piezoelectric ceramic plate 1 generates AC electricity.

FIG. 7 shows an example of a piezoelectric generator A4 using a spring material. The piezoelectric generator A4 suspends the steel ball 4 using a spring material 18, arranges the cushion plate 3 below the steel ball 4, and attaches the piezoelectric ceramic plate 1 to the center of the cushion plate 3 using the adhesive 5 only. The protector plate 2 is fixed to the center of the piezoelectric ceramic plate 1. The material and the like of each member are as described above. When the piezoelectric generator A4 is floated in an environment of rocking underwater, the steel balls 4 repeatedly hit the piezoelectric ceramic plate 1 by the expansion and contraction movement of the spring member 18, and the piezoelectric ceramic plate 1 is excited to generate vibration to generate power.

A piezoelectric generator A5 shown in FIG. 8 has a piezoelectric ceramic body 1 at both ends of a housing 18 having both ends closed.
0 (PZT1) and 10 (PZT2) are opposed to each other with their axes shifted slightly.
Electric power is generated by colliding zeros.

The cushion plates 13 and 13 are adhered to both sides of the housing 18 with adhesives 16 and 16, and the adhesives 15 and 15 are used only at the central portions of the cushion plates 13 and 13. Piezoelectric ceramic body 10, 10
Glue. A protector plate 2 is fixed to the center of the facing surfaces of the two piezoelectric ceramic bodies 1. In the present embodiment, the two piezoelectric ceramic bodies 10, 10 are formed to be curved in an arc shape.

The piezoelectric ceramic body 10 (PZT)
1) and 10 (PZT2) are two circular plate-shaped piezoelectric ceramic elements 10a having the same material, similar shape, and the same thickness.
10b is joined by reversing the polarity of the polarization of each of the ceramic elements 10a and 10b. By joining the ceramic elements 10a and 10b, the two ceramic elements 10a and 10b vibrate flexibly around the joint surface (a portion that does not expand or contract). In this case, the configurations of the power generation system and the charging system, the piezoelectric ceramic element, the cushion plate, and the protector plate are the same as those of the piezoelectric generators A1 to A4, and thus the detailed description thereof is omitted here.

In this embodiment, the case where the piezoelectric ceramic bodies 10, 10 are supported via the adhesive 15 and the cushion material 13 has been described as an example. However, instead of this, one or both of the piezoelectric ceramic bodies 10 are supported. 10, 10 fixed to one end of a spring (may be supported upward or downward)
The other end of the piezoelectric ceramic body 1 is attached to the housing 18 and the spring material is expanded and contracted left and right and vertically oscillated.
0 and 10 may collide.

Since the piezoelectric generator A5 is configured to generate power by colliding the piezoelectric ceramic bodies 10 with each other as described above, the configuration as a power generation device is extremely simplified, and the piezoelectric generator A5 has a very simple structure. Ceramic body 1
Since 0 and 10 are curved in an arc shape, the piezoelectric ceramic bodies 10 and 10 can be disposed as close as possible in a normal state, so that the entire device can be further miniaturized. It is particularly suitable for the lure of the present invention which is a small product.

The piezoelectric generator A6 shown in FIG. 9 has a piezoelectric ceramic body 10 (PZT1) similar to the piezoelectric generator A5.
And a piezoelectric ceramic body 10 (PZT2), and a third piezoelectric ceramic body 10 (PZT3) inside the housing 18 between the piezoelectric ceramic body 10 (PZT1) and the piezoelectric ceramic body 10 (PZT2). The piezoelectric ceramic body 10 (PZT3) is suspended from above by swinging the piezoelectric ceramic body 10 (PZT3) in the left-right direction, whereby the piezoelectric ceramic body 10 (PZT1) or the piezoelectric ceramic body 10 (PZT2) to collide with the piezoelectric ceramics 10 (PZT1), 10 (PZT2), 10 (PZT2).
3) Except that each vibration is excited and each piezoelectric ceramic body 10 is repeatedly expanded and contracted to generate AC electricity, other configurations and operations are the same as those of the piezoelectric generator A5. Since it is configured, its detailed description is omitted here. The piezoelectric ceramic body 10
In the case of (PZT3), since the colliding portion is different from the other piezoelectric ceramic bodies 10 (PZT1) and 10 (PZT2), the protector plate 12 is connected to the piezoelectric ceramic body 10 (PZT3).
Both generators are different in that they are disposed from both end sides of ZT3) to the periphery.

Therefore, the piezoelectric generator A according to each embodiment described above
According to 5, A6, the structure is simpler than that of the piezoelectric generators A1 to A4, the size can be reduced, and the manufacturing cost can be reduced. Therefore, it is more practical for lures.

In each of the piezoelectric generators A5 and A6, a case has been described in which the piezoelectric ceramic body is formed in an arc shape and the piezoelectric ceramic body is directly collided to generate electric power. However, the present invention is not limited to this. Considering the difficulty and cost of manufacturing, the piezoelectric ceramic body is formed into a flat plate like the piezoelectric generators A1 to A4, and is adhered to the striking surface of the piezoelectric ceramic body. The protector plate to be formed is formed in a shape protruding from the hitting surface portion, for example, a hemispherical shape, a cylindrical shape, or a polygonal column shape, or one protector plate is formed in a U-shaped cross section, and the other protector plate is formed. By forming the protector plate into a size and a shape that can be inserted with a small gap in the recess of the one protector plate, the piezoelectric generator can be further reduced in size and the cost can be reduced. That of the desirable.

The mounting directions and the positions of the piezoelectric generator A and the charger B with respect to the lure main body H are not limited to those shown in the drawings. It is desirable to provide the beating body 4 in a location where the reciprocating motion of the hitting body is large along the moving direction of the hit body 4. Since the line is generally attached to the head of the lure, it is preferable to provide the piezoelectric generator A and the like at a portion closer to the tail. Of course,
If the lure device has a large vertical movement, the moving direction of the hit body may be set to the vertical direction. Further, for a lure that moves in a complicated manner, the guide of the hit body can be curved instead of straight. Furthermore, a current plate is not always necessary, but if this is omitted,
By cutting off the head in a plane, the movement can be complicated and efficient power generation can be realized.

[0048]

As described above, in the lure according to the present invention, a luminous body which is disposed in a watertight lure body and irradiates light to the outside, and supplies power to the luminous body Rechargeable battery, and a piezoelectric generator connected to the rechargeable battery,
Wherein the piezoelectric generator is formed of a layered piezoelectric ceramic plate in which two plate-shaped piezoelectric ceramic elements are joined with the polarization reversed.
Because one side or both sides of this piezoelectric ceramics plate is configured so that the beating body hits and generates power due to rocking due to water resistance when the lure is pulled, there are very few mechanical working parts Because there are few failures and power is generated simply by swinging the lure underwater by drawing a line, the power generation efficiency is good, and the number of parts is significantly larger than that of this type of conventional power generation lure. Since it is reduced, it has an effect that it is suitable and practical for lures that are small products.

Further, since the structure in which the layered piezoelectric ceramic body is supported by the cushion material is employed, the vibration of the piezoelectric ceramic body lasts long, so that the power generation efficiency is improved, and particularly, maintenance work is required and the underwater operation is performed underwater. Light emission is automatically started by repeating the pulling operation, so that lure fishing can be freely enjoyed without the need to replace batteries and the like.

Further, according to the piezoelectric generator mounted on the lure according to the present invention, two piezoelectric ceramic elements having the same material, similar shape and the same thickness are formed by reversing the polarization of each ceramic element. By joining, the joint surface of the two ceramic elements is formed so as to bend and vibrate at the center (a part that does not expand or contract), so that the expansion and contraction of the piezoelectric ceramic element is appropriately performed, and the effect of further improving the power generation efficiency is obtained. .

Further, when the piezoelectric ceramics are made to collide with each other and vibrate, the size of the piezoelectric power generation can be further reduced and the cost can be reduced.

Further, since the protector plate is attached to the portion of the piezoelectric ceramic body to be hit, there is an effect that the piezoelectric ceramic element is effectively protected against the impact load of the piezoelectric ceramic body. The shape of the protector plate is, for example, a shape protruding from the hitting surface portion of the piezoelectric ceramic body so that a direct collision vibration can be easily obtained even if the piezoelectric ceramic body is formed in a plate shape, for example, a semi-spherical shape. By forming it into a cylindrical or polygonal column shape, it is possible to further reduce the manufacturing cost.

Further, since each of the piezoelectric ceramic elements is joined in plural layers, there is an effect that the strength of the piezoelectric ceramic element can be maintained. In addition, since a titanium-zirconate-zinc-based material is used for the piezoelectric ceramic element, an excellent effect that the power generation efficiency is very good and practically effective can be obtained.
