TECHNICAL FIELD The present invention relates to a fishing tackle,
For example, the present invention relates to a light emitting device for fishing tackle and a light emitting fishing tackle in which a light emitting device is incorporated in a simulated bait or a float so that the simulated bait or the float emits light.

[0002]

2. Description of the Related Art Conventionally, when a lure that emits light is effective when a lumber is used for fishing, a prior art in which a lure is provided with a light emitter is disclosed in, for example, Japanese Patent Laid-Open No. 11-25.
It is disclosed in Japanese Patent No. 3071.

In this prior art, an LED (light emitting diode) is used as a light emitting device, and an electromotive force generated by a piezoelectric element is used as the power source. The electromotive force generating structure of this piezoelectric element is a cylinder. A piezoelectric element is attached to one end of the cylindrical body, and a rollable spherical body is enclosed inside the cylindrical body. When kinetic energy is applied to the cylindrical body in the longitudinal direction, the spherical body is formed. The spherical body collides with the piezoelectric element due to the relative movement between the piezoelectric element and the piezoelectric element, an electromotive force is generated in the piezoelectric element by the collision, and the LED is turned on and emitted by this electric power.

However, in the above structure, the spherical body is LE.
A certain amount of weight is required to give the piezoelectric element the shock necessary for lighting and emitting D. If this is built into the lure, the weight balance becomes unbalanced and the friction resistance between the cylindrical body and the spherical body is also added. As a result, the spherical body remains in contact with the piezoelectric element or is separated from the piezoelectric element in many cases, resulting in a decrease in sensitivity. There is a problem that the state cannot be obtained.

SUMMARY OF THE INVENTION An object of the present invention is to provide a light emitting device for fishing tackle and a light emitting fishing tackle which can sufficiently obtain the electromotive force of the piezoelectric element even with a small vibration and can obtain effective light emission.

[0006]

According to the present invention, a piezoelectric element or a holding medium holding the piezoelectric element is provided with a weight so that the piezoelectric element is distorted by the vibration of the weight. It is a light emitting device for fishing tackle in which a light emitting device is connected to be able to light.

According to this structure, when kinetic energy is applied to the weight, the weight is in a non-contact state, so that the piezoelectric element is vibrated effectively without energy loss, and this vibration distorts the piezoelectric element. Then, electromotive force is generated, and the electromotive force causes the light emitting device to light up.

The holding medium may be formed of a member having elasticity, for example, a leaf spring, or may be formed of a conductive resin of an intermediate layer into a plate-like body. This includes attaching the piezoelectric element to one or both surfaces of these plate-like elastic members, and further to the entire surface or a partial position of the plate surface.

The plate-like elastic member can set a position apart from the weight as a supporting position of the piezoelectric element or the holding medium.

The light emitting device is an LED (light emitting diode).
And small lamps, and other light sources that light up with electrical energy.

As an embodiment, it is possible to coat the piezoelectric element and the light emitter with a coating that allows the light of the light emitter to pass through and allows the vibration of the piezoelectric element.

Further, the cover of the light emitting device for fishing tackle can be formed into the shape of a pseudo bait to provide a light emitting fishing tackle, for example, a light emitting lure can be formed.

Further, the cover of the light emitting device for fishing tackle can be formed in the shape of a floating body to provide a light emitting fishing tackle.
It can form a float that is effective for night use. As another form, a fishing tackle accessory can be formed.

[0014]

According to the present invention, since the weight is in a non-contact state, the piezoelectric element can be vibrated without loss of kinetic energy received by the weight, and even a small amount of kinetic energy received by the light emitting device for fishing tackle is used. Can be vibrated,
Effective light emission can be obtained, and a light-emitting device with high sensitivity can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As an example of a light emitting device for fishing tackle, an example in which a light emitting device is formed on a lure is shown. In FIGS. 1 and 2, the lure 10 described above has a fishing hook 12 vertically provided on a front portion, an intermediate portion and a rear portion of a lure body 11. The lure body 11 is made of synthetic resin that allows light to pass through, and is formed in the shape of a dummy bait.

The above-described light emitting device 13 emits light by the power generator 14 formed in a rectangular plate shape, the weight 15 crimped and fixed to the free end of the power generator 14, and the electromotive force from the power generator 14.

Since 7 and the holding plate 18 have elasticity, they vibrate in both the forward and reverse directions in the thickness direction of the plate, and this vibration causes distortion in the piezoelectric elements 17 and 17 to generate an electromotive force. , 16 lights up. It should be noted that this lighting turns on one of the LEDs 16 and 16 corresponding to the forward or reverse direction, and both LEDs 16 and 16 are turned on by both forward and reverse vibrations.

Of course, even if the lure 10 is moved statically, since the weight 15 is in a non-contact state, the piezoelectric elements 17 and 17 and the holding plate 18 can be vibrated even with a slight kinetic energy, and the sensitivity is high. It is possible to obtain excellent light emission.
