Description

  The present invention relates to a light-emitting fishing rod that can be used for night fishing and allows easy visual recognition of fishing fish.

Conventionally, in the case of night fishing, several glowing fishing rods have been proposed in order to visually recognize the pull of the fish and know the timing of fishing in accordance with the pull. Examples thereof include those in which a luminous substance is applied or pasted on the tip of a cocoon and those in which a light emitting element emits light by a simple power source. Among these, for the latter, those using LEDs as light emitting elements, those using electroluminescence elements, those equipped with light sources such as small light bulbs, and elements that emit light upon receiving light from the light sources There are things added to the. In addition, as another way of dividing, there are a type in which a light emitter is provided inside the bag and a type in which the light emitter is provided outside the bag. Looking back at these examples in the patent literature, it looks like this. First, it is assumed that the light emitter is installed on the outside of the bag, Patent Document 1, Patent Document 2,
There are Patent Document 3, Patent Document 4, Patent Document 5, and Patent Document 6. FIG. 2 is a diagram showing a ridge in which such a light emitter is installed outside the ridge. A light emitter 202 and a power source 203 are attached to the distal end portion of the distal tip 201. In some cases, the power source 203 is installed elsewhere and the power source is supplied to the light emitter 202 by wiring. In general, the light-emitting body installed outside the ridge has the disadvantages that the yarn is easily entangled and corroded in seawater. In particular, Patent Document 4, Patent Document 5, and Patent Document 6 take measures to make the surface of the ridge conductive, avoiding special routing of the electrical wiring from the power source to the light emitter. This has the disadvantage that the conductive part is vulnerable to scratches. On the other hand, when the light emitter is inside the bag, it is difficult to arrange the light emitter inside the bag, but there are proposals shown in Patent Document 7, Patent Document 8, and Patent Document 9. FIG. 3 is a diagram showing a conventional product in which a light emitter is disposed inside a bag. First, as shown in FIG. 3A, in Patent Document 7, the light emitter has the light emitter 302 disposed in the approximate center of the tip hook 301, and the power source 303 is installed on the end of the tip hook 301. Power is supplied from the power supply 303 to the light emitter 302 through the wiring 304. In order to route the wiring, it is difficult to insert the light-emitting body up to the thin tip portion because it does not enter to the inside unless it is put in a hard tube. In order to avoid this drawback, as shown in FIG. 3B, in Patent Document 8, the light emitter 302 connected to the power source 303 is installed on the side of the tip of the tip ridge 301, and the long wiring Is avoided. If this is the case, the location where the light is emitted is far from the tip of the cocoon, which makes it difficult. Therefore, a secondary light emitter 305 that receives light from the illuminant 302 such as a phosphor and emits secondary light is additionally provided at the tip of the heel. It is. Such a configuration is easy to manufacture, but has a disadvantage that an extra secondary light emitter 305 is required. In Patent Document 9, although an electroluminescence element is used as a light emitter attached to the inside of the bag, there is a disadvantage that the element and the power source are expensive.

In view of the above circumstances, the problem to be solved is a fishing rod with a built-in illuminant that does not have anxiety about thread entanglement, and does not have a long wiring to the illuminant. It is an object of the present invention to provide a light-emitting fishing rod that does not require a typical light-emitting body, and that can be constructed inexpensively and easily.

Means for solving the above-mentioned problem is that an optical fiber is attached to receive light from a light emitter such as an LED (light emitting diode) connected to a power source such as an elongated cylindrical lithium battery (without a long wiring), and a fishing rod A light-transmitting window having a transparent or semi-transparent substantially distal end portion of the tip end is provided, and the length of the optical fiber is such that the tip reaches the light-transmitting window when the optical fiber is inserted. Hereinafter, it demonstrates along a claim.

The invention according to claim 1 is a light emitting fishing rod, and is transparent or translucent and has a light transmitting window that transmits light, a light emitting body, and a light emitting body, so as to receive light emitted from the light emitting body. A fishing rod having at least a light receiving tip and an optical fiber for guiding the light to the tip side of the tip rod and a battery for supplying power to be connected to the light emitter to emit light. When the body and the battery are installed at a tip that is not the tip of the tip of the tip, the length of the optical fiber is set to a length at which the light transmitting window is located. This makes it possible to provide a light-emitting fishing rod that is inexpensive and easy to manufacture.

According to a second aspect of the present invention, in the light emitting fishing rod according to the first aspect, the light emitter is a light emitting diode.

The invention described in claim 3 is the light-emitting fishing rod according to claim 1 or 2, wherein the optical fiber has a diameter of 0.5 mm or more. This facilitates the insertion of the optical fiber during production.

According to a fourth aspect of the present invention, in the light-emitting fishing rod according to any one of the first to third aspects, the tip of the optical fiber on the side where the light transmitting window is located is cut obliquely. .
Thereby, light can be effectively emitted in the direction of the light transmission window.

According to a fifth aspect of the present invention, in the light emitting fishing rod according to any one of the first to fourth aspects, in order to arrange the light receiving tip of the optical fiber so as to receive the light emitted from the light emitter, The holder for holding the optical fiber and the light emitter has a shape corresponding to the diameter of each of the optical fiber and the light emitter inserted into the holder. Thereby, the light emitted from the light emitter by the holder can be effectively transmitted to the optical fiber.

Since it is configured as described above, the light-emitting fishing rod according to the present invention can be configured with a few elements that are easy to manufacture and inexpensive, such as alignment of the light-emitting body or light-emitting portion, without worrying about thread tangles.

The light-emitting fishing rod according to the present invention includes a light-emitting body, an optical fiber having a light-receiving tip disposed so as to receive light emitted from the light-emitting body, and a battery connected to the light-emitting body and supplying a power source for light emission. An optical fiber that is inserted and has a light-transmitting window that transmits transparent or translucent light at least at the center of the tip of the hollow tip so that the light emitter and the battery are inserted and arranged in the tip. The tip is set to a length that is arranged at a portion where the light transmitting window is located. Hereinafter, description will be made using examples.

FIG. 1 is a diagram showing an embodiment of a light-emitting fishing rod according to the present invention. In 1-A, a hollow tip rod 101 made of a synthetic resin such as carbon, glass fiber, or polyester has a light emitter 102 such as an LED (light emitting diode) and a battery 103 such as a lithium battery that supplies power to the light emitter 102. An optical fiber 104 that receives and guides light emitted from the light emitter 102 is inserted. When there is a transparent window 105 that transmits transparent or translucent light at any part in the center from the tip, and when the light emitter 102 and the battery 103 of the tip collar 101 are arranged at the end of the tip collar The length of the optical fiber is set such that the tip of the optical fiber is disposed at a portion where the light transmission window 105 is located.

1-B of FIG. 1 shows an enlarged view of the light emitter, battery, and optical fiber that are inserted into the tip hook 101. Here, although it is an example of the cylindrical battery 103 which is easy to use, the anode and the cathode of the battery are the first electrode 103A having a pin or protrusion shape and the second electrode 103B which is the surface of the cylinder. The battery housing 106 into which the battery 103 is inserted has a third electrode 106A and a fourth electrode 106B in the recess so as to correspond to the first electrode 103A and the second electrode 103B which is the surface of the cylinder. These electrodes are connected to the fifth electrode 102A and the sixth electrode 102B of the light emitter 102. Therefore, when the battery 103 is inserted into the battery housing 106 in the direction shown in the drawing, power is supplied to the light emitter to emit light. If the battery 103 is inserted in the reverse direction (with the pin or protruding first electrode 103A facing outward), the first electrode 103A is not connected and therefore no light is emitted. In other words, it plays the role of a switch. Of course, you may attach a switch separately. When not in use, the battery 103 may be inserted in such a direction. The optical fiber 104 and the light emitter 102 are held by a holder 107. That is, in the gripping state, the light is emitted from the light emitter 102 so as to enter the light receiving end of the optical fiber 104. In this example, it is also possible to effectively diverge light from the translucent window 105 by obliquely cutting the tip of the optical fiber 104 on the side close to the tip. The shape of the holder 107 is such that the side on which the optical fiber 104 is inserted corresponds to the diameter of the optical fiber 104, and the side on which the light emitter 102 is inserted corresponds to the diameter of the light emitter 102.

As described above, in the light emitting fishing rod of the present invention, since the light emitter and the like are built inside the rod, there is no concern about thread entanglement and it is not exposed to the outside. Of course, there is no long wiring between the light emitter and the battery that may impair the positioning accuracy of the light emitter as in the conventional product. It is easy to manufacture because it may be arranged on the tip side of the light source, and it is not necessary to provide a second light emitting part that increases the cost as in the conventional product, and the tip of the optical fiber extends to the position of the translucent window. Light can be obtained at any position on the heel. If the thickness of the optical fiber is such that it does not bend so much, for example, 5 mmφ or more, preferably 1 mmφ, the tip of the optical fiber is self-aligned with the transparent window portion by simply inserting the battery and the light emitter. It is easy to manufacture because it is arranged and does not require troublesome alignment in a hollow narrow hole. Of course, the translucent window may be the entire surface of the tip. The optical fiber also has an advantage that the hole wall becomes a guide path in a hollow narrow hole and can be easily inserted.

As described above, the light-emitting fishing rod according to the present invention is easy and inexpensive to manufacture, and can set the position where the tip light shines at an arbitrary position. Has great utility.
