However, the fishing line threading tool in Patent Document 1 is difficult to store, which means that it is often lost or forgotten to be brought to the fishing spot. In addition, because it is made of metal, there is a risk of damaging the inside of the fishing rod.

The present invention was made to solve the above problems, and aims to provide a fishing line threading tool that is easy to operate and store.

To solve the above problem, the present invention provides a fishing line threading tool used to thread a fishing line inside a through-rod having a fishing line introduction section for introducing the fishing line and a fishing line outlet section for leading out the fishing line, the fishing line threading tool being elongated and made of thermoplastic resin, capable of changing its shape to a softened or hardened state at the glass transition temperature, and being inserted into the fishing line introduction section and removed from the fishing line outlet section in a hardened state below the glass transition temperature after being connected to the fishing line.

According to the present invention, the shape can be changed between a softened state and a hardened state depending on the temperature. In other words, when it is inserted into a fishing rod together with the fishing line, it is in a hardened state, and when it is stored or connected to the fishing line, it is in a softened state. In this way, by changing the shape according to the situation, it is possible to improve operability and storability. When storing, it is in a softened state, and for example, it can be wrapped around a fishing rod or a storage tool.

The thermoplastic resin preferably has a glass transition temperature of 27°C to 47°C.

According to the present invention, for example, it can be softened at body temperature and hardened by wetting with water.

The thermoplastic resin is preferably made of polyvinylidene fluoride or polyvinyl acetate.

The present invention allows materials to be procured cheaply and easily.

It is preferable that the width is greater than or equal to 1 mm and less than 3 mm.

The present invention can further improve operability.

It is also preferable that the tip is provided with a cover member that reduces in diameter in the insertion direction.

The present invention allows for easy insertion of a through-hole fishing rod.

It is also preferable that a magnetic body is attached to the cover member.

According to the present invention, the magnetic body can be pulled from the outside using a magnet or the like, making it easier to insert the fishing rod through the rod.

The present invention provides a fishing line threading tool that is easy to operate and store.

First Embodiment
A first embodiment of the fishing line threading tool of the present invention will be described below with reference to the attached drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated descriptions will be omitted as appropriate.

As shown in FIG. 1, the through-rod 1 comprises a rod 2, a reel seat 3, an end cap 4, a fishing line lead-in section 5, and a fishing line outlet section 6. From the tip side, the through-rod 1 is provided on the rod 2 with the fishing line outlet section 6, the fishing line lead-in section 5, the reel seat 3, and the end cap 4 in that order.

The rod 2 is a telescopic rod that includes a base tube 2A, a middle tube 2B, and a tip tube 2C. The base tube 2A, the middle tube 2B, and the tip tube 2C are all cylindrical and made of, for example, fiber-reinforced resin. The rod 2 may be a joint rod, and the number of tubes that make up the rod 2 may be any number as long as it is one or more.

The reel seat 3 is a cylindrical member to which the fishing reel R with the fishing line T wound around it is detachably fixed. There are no particular restrictions on the material of the reel seat 3, but in this embodiment it is made of resin in consideration of weight reduction. The rod 2 is inserted into the hollow space inside the reel seat 3 and fixed in place by adhesive.

The end cap 4 is a cylindrical member with a bottom that seals the end of the base rod tube 2A on the base side. The fishing line introduction section 5 is a member that introduces the fishing line T that is reeled out from the reel R into the inside of the rod shaft 2. As shown in FIG. 2, the fishing line introduction section 5 has a fishing line introduction guide 5A that bulges out from the side of the base rod tube 2A and a line introduction hole 5B formed in the side of the base rod tube 2A.

The fishing line introduction guide 5A is provided with a line introduction guide ring 5C, and the line introduction hole 5B is provided with a guide ring 5D. These line introduction guide rings 5C and guide rings 5D are for smoothly sliding the fishing line T, and are made of, for example, ceramic or metal, and are attached at a predetermined position.

A butt plug 8 is attached to the rear end of the middle rod tube 2B, and a guide ring 8A is attached to the butt plug 8 to guide the fishing line T introduced from the fishing line introduction section 5. This guide ring 8A is made of, for example, ceramic, aluminum, stainless steel, or other metal.

As shown in FIG. 1, a fishing line outlet 6 is attached to the tip of the tip tube 2C. The fishing line outlet 6 is integrally formed into a cylindrical shape from, for example, resin or metal, and is attached by fitting it into the tip of the tip tube 2C.

Next, an embodiment of a fishing line threading tool used to thread a fishing line through a through-hole fishing rod 1 configured as described above will be described with reference to Figures 1 to 4.

As shown in FIG. 3, the fishing line threading tool 10 has an elongated shape. The width of the fishing line threading tool 10 may be set as appropriate within a range that allows it to be inserted through the rod 2 together with the fishing line T, and may be set as appropriate within a range of, for example, 1 mm or more and less than 3 mm. The cross-sectional shape of the fishing line threading tool 10 is rectangular, but it may also be other shapes such as circular, elliptical, or triangular. The fishing line threading tool 10 may also be in the shape of an elongated strip.

The fishing line threading tool 10 is made of a thermoplastic resin, and can change its form between a softened state and a hardened state at the glass transition temperature. The fishing line threading tool 10 is made of a thermoplastic resin whose glass transition temperature is near body temperature. Specifically, it is preferable to use a thermoplastic resin whose glass transition temperature is 27°C or higher and 37°C or lower. Examples of the thermoplastic resin that can be used include polyvinylidene fluoride and polyvinyl acetate. Also, examples of the thermoplastic resin that can be used include polymer alloys that are a mixture of two or more types of polymers or copolymers. Examples of combinations include PA/PP (polyamide/polypropylene), PA/PPE (polyamide/polyphenylene ether), PA/ABS (polyamide/acrylonitrile-butadiene-styrene copolymer synthetic resin), PBT/ABS (polybutylene terephthalate/acrylonitrile-butadiene-styrene copolymer synthetic resin), and PP/PC (polypropylene/polycarbonate).

The fishing line threading tool 10 in the softened state has flexibility and can be changed into a desired shape. For example, as shown in FIG. 5, it can be stored wrapped around the outer surface of the base rod tube 2A. Although not specifically shown, it can also be stored wrapped around a storage tool. In addition, in the softened state, it can be tied to the fishing line T and connected as shown in FIG. 4.

As shown in Figure 3, the fishing line threader 10 can be hardened by wetting it with water or the like to bring it below its glass transition temperature. For example, by immersing the fishing line threader 10 in a straight, tensioned state in water, a hardened, straight fishing line threader 10 can be formed. Note that water is not the only means for cooling the fishing line threader 10. For example, if the outside temperature is below 20 degrees, the fishing line threader 10 can be hardened simply by leaving it in a straight, tensioned state.

For example, after the fishing line T and the fishing line threading tool 10 are connected in a softened state, water is brought into contact with the fishing line threading tool 10 to harden it into a straight line. The fishing line threading tool 10 with the fishing line T attached is then inserted through the fishing line introduction section 5, moved inside the rod 2, and removed from the fishing line lead-out section 6 at the tip, allowing the fishing line T to be inserted into the rod 2.

The fishing line threader 10 according to the present embodiment described above has an elongated shape, is made of thermoplastic resin, and can change its state between a softened state and a hardened state at the glass transition temperature. This allows the user to change the state between a softened state and a hardened state depending on the temperature. In other words, when storing the fishing line threader 10 or connecting it to the fishing line T, the temperature of the fishing line threader 10 is raised to above the glass transition temperature, causing the fishing line threader 10 to be in a softened state.

On the other hand, when the fishing line threader 1 is inserted into the fishing rod 1 together with the fishing line T, the temperature of the fishing line threader 10 is lowered below the glass transition temperature to harden the fishing line threader 10. The hardened fishing line threader 10 is inserted into the fishing line introduction section 5 and removed from the fishing line lead-out section 6, allowing the fishing line T to be guided into the rod 2. In this way, by changing the shape to suit the situation, operability and storability can be improved. In addition, because the fishing line threader 10 is made of resin, it is possible to prevent damage to the inside of the fishing rod 1.

Thermoplastic resin has a glass transition temperature of 27°C to 47°C. In other words, by using a thermoplastic resin whose glass transition temperature is close to human body temperature, for example, the temperature of the fishing line threading tool 10 can be raised by holding it in the hand, thereby softening it. Also, by wetting it with seawater or river water, the fishing line threading tool 10 can be cooled and hardened. Therefore, it is easy to switch between the softened and hardened states without using special tools, etc.

The thermoplastic resin is composed of polyvinylidene fluoride or polyvinyl acetate. Therefore, it can be easily switched between a softened state and a hardened state. In addition, the material can be procured cheaply and easily.

In addition, if the width of the fishing line threading tool 10 is 1 mm or more, it is possible to prevent the fishing line threading tool 10 from bending midway when inserted into the rod 2 in a hardened state, making it difficult to insert. In addition, if the width of the fishing line threading tool 10 is less than 3 mm, it is easier to insert the fishing line threading tool 10 into the rod 2 and it is easier to change shape when in a softened state. This makes it easier to operate.

Second Embodiment
Next, a fishing line threading tool 10A according to a second embodiment of the present invention will be described as shown in Fig. 6. The fishing line threading tool 10A of the second embodiment differs from the first embodiment in that a cover member 20 is attached to the tip portion of the fishing line threading tool (which is the same as the fishing line threading tool 10 of the first embodiment).

The cover member 20 is constructed by stacking a pair of cover bodies 21 on top of each other. The cover body 21 is hollow inside. The cover body 21 is made of ABS resin, ASA resin, PLA resin, PP resin, PET resin, epoxy resin, acrylic resin, polycarbonate resin, polyamide resin, or resins containing reinforcing fibers such as carbon. The cover body 21 can be easily manufactured, for example, by a 3D printer.

The cover body 21 is semi-dome shaped and includes a bottom 21a, a rear end 21b, a protruding portion 21c, and a tip 21d. The bottom 21a faces the other cover body 21. The rear end 21b stands perpendicular to the rear end of the bottom 21a and contacts the fishing line threading tool 10A. The protruding portion 21c protrudes away from the bottom 21a. The tip 21d stands perpendicular to the bottom 21a from the tip of the bottom 21a. The cover body 21 is configured to have a smaller diameter from the protruding portion 21c toward the tip 21d.

The cover member 20 further includes a magnetic body 22. The magnetic body 22 is a material that can become magnetic. The magnetic body 22 is made of, for example, iron oxide, chromium oxide, cobalt, nickel, ferrite, or gadolinium. In this embodiment, the magnetic body 22 is disposed partially between the protruding portion 21c and the tip portion 21d, but it may be disposed over the entire cover body 21. Two or more magnetic bodies 22 may also be disposed.

The fishing line threading tool 10A according to the second embodiment can achieve substantially the same effects as the first embodiment. In addition, the cover member 20 is provided at the tip and reduces in diameter in the insertion direction, making it easier to insert into the rod 2. In addition, the cover bodies 21, 21 can cover the fishing line T and the knot of the fishing line threading tool 10A together, preventing the knot from getting caught inside the rod 2 when the fishing line T is being inserted.

In addition, since the magnetic body 22 is attached to the cover member 20, the magnetic body 22 can be guided from outside the rod 2 by a magnet or the like, so that the fishing line T can be easily inserted into the rod 2.

Although the embodiment of the present invention has been described above, appropriate design changes are possible within the scope of the present invention. For example, in this embodiment, the fishing line introduction section is provided at the base of the rod and the fishing line outlet section is provided at the tip of the rod, but the fishing line threading tool 10 and the fishing line T may be introduced from the tip of the rod and may be led out from the base of the rod. In other words, the tip of the rod may be the fishing line introduction section and the base of the rod may be the fishing line outlet section.
