Description

The present invention relates to a fishing rod having a rod body to which a reel seat is attached.

Conventionally, a fishing rod having a rod body to which a reel seat is attached has been known. The reel seat usually has legs extending in the axial direction of the rod body at each of its front end and rear end. The reel sheet is attached to the rod body by winding the legs together with the rod body with a mounting thread or a resin sheet.

A coating layer made of synthetic resin may be formed on the outside of the mounting thread or the resin sheet in order to improve decorativeness and weather resistance. When the rod body bends, stress acts on the coating layer, and there is a problem that cracks are likely to occur in the coating layer due to this stress.

Techniques for preventing the occurrence of cracks in the coating layer are also known. For example, Japanese Patent Application Laid-Open No. 2011-067123 discloses a fishing rod having a reinforcing sheet arranged so as to extend from the end of the reel sheet to the outer surface of the rod body. Further, Japanese Patent Application Laid-Open No. 2004-194563 discloses a fishing rod in which a low elongation sheet having a lower elongation rate than the attachment thread is arranged between the attachment thread and the leg portion of the reel sheet. In these fishing rods, a reinforcing sheet or a low elongation sheet prevents the edge of the reel sheet from rising from the rod body, thereby preventing the occurrence of cracks in the coating layer.

As described above, it is desired to prevent the occurrence of cracks in the coating layer provided on the outside of the reel sheet.

One of the objects of the present invention is to provide a novel fishing rod in which cracks do not occur in the coating layer covering the legs of the reel sheet. Other objectives of the present invention will become apparent by reference to the entire specification.

The fishing rod according to the embodiment of the present invention has a rod body and legs, and has a reel sheet attached to the outer peripheral surface of the rod body via the legs, and the legs and the outer peripheral surface of the rod body. An adhesive tape arranged between the legs, a fixing layer formed so as to surround the legs and the rod body together, and a resin coating layer formed on the outside of the fixing layer are provided. The adhesive tape has a base material and pressure-sensitive adhesive layers provided on both sides of the base material. In one embodiment, the thickness of the adhesive tape is 0.25 mm to 0.6 mm.

When using a fishing rod, the rod body bends significantly, so that a force acts on the legs of the reel seat in the direction away from the rod body. According to the above embodiment, since the legs of the reel sheet are attached to the rod body by the adhesive tape, it is possible to prevent the legs of the reel sheet from being lifted from the rod body even if the rod body is bent.

Further, at the time of casting, a force in the twisting direction acts from the reel to the legs of the reel seat. According to the above embodiment, since the thickness of the pressure-sensitive adhesive sheet is 0.25 mm or more, the pressure-sensitive adhesive sheet can buffer the force acting on the legs of the reel sheet in the twisting direction.

As described above, by attaching the reel sheet to the rod body via the adhesive sheet having a thickness of 0.25 mm to 0.6 mm, the rod body bends and a force in the direction of lifting from the rod body is applied to the legs of the reel sheet. It is possible to prevent the legs of the reel sheet from peeling off from the rod body both when the action is applied and when a force in the twisting direction is applied to the reel sheet. As a result, it is possible to suppress the occurrence of cracks in the coating layer covering the legs of the reel sheet.

In one embodiment of the invention, the substrate comprises acrylic foam, polyurethane foam, soft polyvinyl chloride, or polyethylene foam.

According to the above embodiment, the base material of the adhesive tape exhibits an excellent cushioning effect.

In one embodiment of the present invention, the adhesive tape has an adhesive strength of 40 N / cm to 67 N / cm when peeled in the 90 ° direction under the conditions of a temperature of 23 ° C. and a peeling speed of 300 mm / min.

According to the above embodiment, it is possible to prevent the reel sheet from peeling off from the rod body. On the other hand, since the adhesive strength of the adhesive tape is 67 N / cm or less, the reel sheet can be removed from the rod body without damaging the surface of the rod body.

In one embodiment of the present invention, the adhesive tape, a shear adhesive strength at a temperature 23 ° C. is ^{110N / cm 2 ~168N / cm 2} .

When a force in the twisting direction acts on the reel seat, a tensile force in the axial direction of the rod body acts on the legs. According to the above embodiment, since the shearing adhesive force of the adhesive tape is 110 N / cm ² or more, it is possible to prevent the reel sheet from peeling off from the rod body due to the force acting on the reel sheet in the twisting direction.

According to each of the above embodiments of the present invention, it is possible to suppress the occurrence of cracks in the coating layer covering the legs of the reel sheet.

A fixing layer 20a is provided on the outside of the leg portion 14a so as to cover the leg portion 14a and the adhesive tape 15a. Similarly, a fixing layer 20b is provided on the outside of the leg portion 14b so as to cover the leg portion 14b and the adhesive tape 15b. The fixed layer 20a and the fixed layer 20b firmly attach the reel sheet 10 to the original rod 3 together with the adhesive sheet 15a and the adhesive sheet 15b. The fixing layers 20a and 20b are made of a resin sheet or a resin-made mounting thread, which will be described later.

A coating layer 30a is provided on the outside of the fixed layer 20a. Similarly, a coating layer 30b is provided on the outside of the fixed layer 20b. The coating layer 30a and the coating layer 30b are resin coating films provided on the outside of the corresponding fixing layer 20a and the fixing layer 20b so as to cover the corresponding fixing layer 20a and the fixing layer 20b.

When attaching the reel R to the reel seat 10, the movable hood 13 is first moved to a retracted position distal to the fixed hood 12. Next, the rear end of the reel leg R1 of the reel R is inserted into the movable hood at the retracted position, and the front end of the reel leg R2 is inserted into the fixed hood 13. Next, the movable hood 13 is moved forward along the guide groove 11a. As a result, the reel leg R1 is sandwiched between the fixed hood 12 and the movable hood 13. When removing the reel R from the reel seat 10, the movable hood 13 is moved rearward.

Next, a method of attaching the reel sheet 10 to the original rod 3 will be described with reference to FIGS. 4a and 4b. 4a and 4b are diagrams schematically showing a part of a method of attaching the reel sheet 10 to the original rod 3.

When attaching the reel sheet 10 to the middle rod 3, first, the original rod 3, the reel sheet 10, the adhesive tape 15a, the adhesive tape 15b, the adhesive tape 15c, the fixing sheet 20aS, and the fixing sheet 20bS are prepared.

As described above, the original rod 3 is produced by heating and curing the prepreg sheet wound around the core metal.

As the reel sheet 10, any reel sheet that can be attached to the rod body by the adhesive sheet can be used. For example, as the reel sheet 10, a reel sheet formed in a plate shape shown in FIG. 2 can be used.

The fixed sheets 20aS and 20bS are, for example, prepreg sheets obtained by impregnating fibers made of synthetic resin with a resin composition containing a thermosetting resin. The fiber made of this synthetic resin is, for example, a fiber made of one or more selected from the group consisting of polyolefin, polyamide, polyacrylonitrile, and polyester. Thermosetting resin refers to a resin that irreversibly cures due to a chemical reaction when heated. Examples of the thermosetting resin that can be used in the resin composition include urea resin, melamine resin, phenol resin, epoxy resin, unsaturated polyester resin, alkyd resin, and urethane resin. The thickness of the fixed sheets 20aS and 20bS is, for example, 20 μm to 300 μm. Appropriate commercially available products can be used as the fixing sheets 20aS and 20bS.

At least one of the fixed sheets 20aS and 20bS may be a resin sheet that does not contain reinforcing fibers. This resin sheet is, for example, a resin sheet based on a thermosetting resin.

A mounting thread may be used instead of the fixing sheets 20aS and 20bS. The mounting yarn is, for example, a twisted yarn formed by twisting synthetic resin fibers.

In order to attach the original rod 3 to the reel sheet 10, first, as shown in FIG. 4a, the adhesive sheets 15a, 15b, 15c are attached to the outer peripheral surface of the middle rod 3. The pressure-sensitive adhesive sheets 15a, 15b, and 15c are attached to the outer peripheral surface of the original rod 3 via one of the pressure-sensitive adhesive layers (for example, the pressure-sensitive adhesive layer 18).

As shown in FIG. 4a, the adhesive sheets 15a, 15b, and 15c are attached to the same position in the circumferential direction of the original rod 3. In the circumferential direction of the original rod 3, the position of the adhesive sheet 15a, the position of the adhesive sheet 15b, and the position of the adhesive sheet 15c do not have to be exactly the same as each other, and the adhesive sheet 15a faces the leg portion 14a. The adhesive sheet 15b may be provided at a position facing the legs 14b, and the adhesive sheet 15c may be provided at a position facing the sheet body 11. For example, the positions of the adhesive sheets 15a, 15b, and 15c in the circumferential direction may be deviated from each other by 10 ° or less at the central angle of the original rod 3.

Subsequently, the reel sheet 10 is placed on the outer peripheral surface of the original rod 3. The reel sheet 10 is placed on the outer peripheral surface of the original rod 3 so that the leg portion 14a faces the adhesive sheet 15a, the leg portion 14b faces the adhesive sheet 15b, and the sheet body 11 faces the adhesive sheet 15c. Will be done.

Subsequently, pressure is applied to at least the legs 14a and 14b of the reel seat 10 toward the central axis of the main rod 3. The pressure causes the pressure-sensitive adhesive sheets 15a, 15b, and 15c to be crushed. The pressure applied to the legs 14a, 14b is such that the thickness of the adhesive sheets 15a, 15b, 15c is 50% to 85% or less of the thickness before pressurization (for example, 1.1 N / m ² ). And. The pressure applied to the legs 14a and 14b is loaded at ^{0.1 N / mm 2} by, for example, a universal strength tester using an indenter of φ1.3.

Subsequently, while crushing the adhesive sheet 15a, the sheet 20aS is wound by a predetermined ply so as to surround the outer peripheral surfaces of the leg portion 14a and the original rod 3. Similarly, while crushing the adhesive sheet 15b, the sheet 20bS is wound by a predetermined ply so as to surround the outer peripheral surfaces of the leg portion 14b and the original rod 3.

Next, the thermosetting resin contained in the sheets 20aS and 20bS is cured by heating the wound body in which the sheets 20aS and 20bS are wound around the main rod 3. By curing the sheets 20aS and 20bS in this way, the fixed layers 20a and 20b are formed, respectively. The reel sheet 10 is fixed to the main rod 3 by the first fixing layers 20a and 20b.

The winding body can be heated by using a known heating furnace. For example, by putting the winding body in a heating furnace maintained at a predetermined temperature for a predetermined time, the winding body is heated as required to obtain the fixed layers 20a and 20b. When the winding body is heated, a tightening tape may be wound around the winding body so that the sheets 20aS and 20bS wound around the main rod 3 do not move during heating.

After heating, the wound body is taken out of the heating furnace and cooled at room temperature for a predetermined time. After the wound body is sufficiently cooled, the coating layer 30a is formed so as to cover the fixed layer 20a formed on the wound body, and the coating layer 30b is formed so as to cover the fixed layer 20b. Specifically, the coating layers 30a and 30b are coated with a thermosetting resin composition, a UV curable resin composition, or a resin composition other than these so as to cover the fixed layers 20a and 20b, and the coated resin is applied. It is formed by curing the composition. This resin composition is cured by heating or UV irradiation.

According to the above embodiment, since the reel sheet 10 is attached to the original rod 3 by the adhesive tapes 15a and 15b, even if the original rod 3 is bent, the legs 14a and 14b of the reel sheet 10 are attached from the rod body. It can be prevented from floating.

At the time of casting, even if a force in the twisting direction is applied from the reel R to the legs 14a and 14b of the reel sheet 10, the thickness of the adhesive sheets 15a and 15b is 0.25 mm or more. The 15b can buffer the twisting force acting on the legs 14a and 14b of the reel seat 10.

According to the above embodiment, since the shear adhesive force of the adhesive tapes 15a and 15b is 110 N / cm ² or more, the reel sheet 10 is even when a force in the twisting direction acts on the reel sheet 10. Can be prevented from peeling off from the reel 3.

As described above, by attaching the reel sheet 10 to the original rod 3 via the adhesive sheets 15a and 15b, the original rod 3 bends and a force in the direction of lifting from the original rod 3 is applied to the legs 14a and 14b of the reel sheet 10. It is possible to prevent the reel sheet 10 from peeling off from the original rod 3 even when it acts or when a force in the twisting direction acts on the reel sheet 10. As a result, it is possible to suppress the occurrence of cracks in the coating layer 30 that covers the legs 14a and 14b of the reel sheet 10.

Further, according to the above embodiment, since the adhesive strength of the adhesive tapes 15a and 15b is 40 N / cm or more, it is possible to prevent the reel sheet 10 from being peeled off from the main rod 3. On the other hand, since the adhesive strength of the adhesive tapes 15a and 15b is 67 N / cm or less, the reel sheet 10 can be peeled off from the original rod 3 without damaging the surface of the original rod 3.

The dimensions, materials, and arrangement of each component described herein are not limited to those expressly described in the embodiments, and each component may be included within the scope of the present invention. Can be transformed to have the dimensions, materials, and arrangement of. In addition, components not explicitly described in the present specification may be added to the described embodiments, or some of the components described in each embodiment may be omitted.
