Description

  The present invention relates to a fishing rod having a housing on which a reel sheet is attached.

  Conventionally, a fishing rod having a housing to which a reel sheet is attached is known. The reel sheet usually has an axially extending leg at the front and back ends of the reel sheet. The reel sheet is attached to the housing by winding the legs together with the housing with a mounting thread or a resin sheet.

  A coating layer made of a synthetic resin may be formed on the outer side of the attachment yarn or the resin sheet in order to improve the decorative property and the weather resistance. When the housing is bent, a stress is applied to the coating layer, and this stress causes a problem that the coating layer is easily cracked.

  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 disposed so as to extend from the end of a reel sheet to the outer surface of a housing. Further, Japanese Patent Application Laid-Open No. 2004-194563 discloses a fishing rod in which a low elongation sheet having an elongation rate lower than that of the attachment yarn is disposed between the attachment yarn and the leg portion of the reel sheet. In these fishing rods, the reinforcing sheet and the low elongation sheet prevent the end of the reel sheet from rising from the housing, thereby making it possible to prevent the occurrence of cracks in the coating layer.

  As described above, it is desirable 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 free of cracks in the coating layer covering the legs of the reel sheet. Other objects of the invention will become apparent by reference to the entire specification.

  A fishing rod according to an embodiment of the present invention has a rod body and a leg portion, and a reel sheet attached to the outer peripheral surface of the rod body through the leg portion, the leg portion and the outer peripheral surface of the rod body And a fixing layer formed to surround the leg portion and the casing together, and a resin coating layer formed on the outside of the fixing layer. The pressure-sensitive adhesive tape has a substrate and a pressure-sensitive adhesive layer provided on both sides of the substrate. In one embodiment, the thickness of the pressure-sensitive adhesive tape is 0.25 mm to 0.6 mm.

  During use of the fishing rod, a large deflection of the rod causes a force in a direction away from the rod to act on the legs of the reel sheet. According to the above-described embodiment, since the legs of the reel sheet are attached to the housing by the adhesive tape, it is possible to prevent the legs of the reel sheet from being lifted from the housing even if the housing is bent.

  Also, during casting, a force in a twisting direction acts on the legs of the reel sheet from the reel. According to the above embodiment, since the adhesive sheet has a thickness of 0.25 mm or more, the adhesive sheet can buffer the force in the twisting direction acting on the legs of the reel sheet.

  As described above, by attaching the reel sheet to the case via the pressure-sensitive adhesive sheet having a thickness of 0.25 mm to 0.6 mm, the force in the direction in which the case is lifted and the leg of the reel sheet is lifted from the case It is possible to prevent the legs of the reel sheet from being peeled off from the case, either when it acts or when a force in the twisting direction acts on the reel sheet. Thereby, the occurrence of cracks in the coating layer covering the legs of the reel sheet can be suppressed.

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

  According to the said embodiment, the base material of an adhesive tape exhibits the buffer effect excellent.

According to the above embodiment, it is possible to prevent peeling of the reel sheet from the housing. On the other hand, since the adhesive strength of the adhesive tape is 67 N / cm ² or less, the reel sheet can be removed from the housing without damaging the surface of the housing.

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 sheet, an axial tensile force of the housing acts on the legs. According to the above embodiment, since the shear adhesive force of the adhesive tape is 110 N / cm ² or more, it is possible to prevent peeling of the reel sheet from the housing due to the force in the twisting direction acting on the reel sheet.

  According to 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.

  Next, with reference to FIGS. 4a and 4b, a method of attaching the reel sheet 10 to the former 3 will be described. FIGS. 4a and 4b schematically show a part of the method of attaching the reel sheet 10 to the former 3. FIG.

  When the reel sheet 10 is attached to the middle rod 3, first, the main 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.

  The main rod 3 is created by heating and curing the prepreg sheet wound around the core as described above.

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

  The fixing 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. A thermosetting resin refers to a resin which hardens irreversibly by a chemical reaction when it is heated. As a thermosetting resin which can be used for the said resin composition, there exist a urea resin, a melamine resin, a phenol resin, an epoxy resin, unsaturated polyester resin, an alkyd resin, and a urethane resin, for example. The thickness of the fixing sheets 20aS and 20bS is, for example, 20 μm to 300 μm. Suitable commercial products can be used as the fixing sheets 20aS and 20bS.

  At least one of the fixing sheets 20aS and 20bS may be a resin sheet not containing reinforcing fibers. The resin sheet is, for example, a resin sheet having a thermosetting resin as a base material.

  An attachment thread may be used instead of the fixed sheets 20aS and 20bS. The attachment yarn is, for example, a twisted yarn formed by twisting a synthetic resin fiber.

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

  The adhesive sheets 15a, 15b, 15c are attached at the same position in the circumferential direction of the main rod 3, as shown in FIG. 4a. 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 in the circumferential direction of the main collar 3, and the adhesive sheet 15a faces the leg 14a, The adhesive sheet 15 b may be provided at a position facing the leg 14 b and the adhesive sheet 15 c facing the sheet main body 11. For example, the circumferential positions of the adhesive sheets 15a, 15b, and 15c may be offset from each other by 10 ° or less at the central angle of the main ridge 3.

  Subsequently, the reel sheet 10 is placed on the outer peripheral surface of the main frame 3. The reel sheet 10 is placed on the outer peripheral surface of the former collar 3 so that the leg 14a faces the adhesive sheet 15a, the leg 14b faces the adhesive sheet 15b, and the sheet main body 11 faces the adhesive sheet 15c. Be done.

Subsequently, pressure is applied to at least the legs 14 a and 14 b of the reel sheet 10 toward the central axis of the former 3. The pressure causes the adhesive sheets 15a, 15b and 15c to be crushed. The pressure applied to the legs 14a and 14b is such that the thickness of the adhesive sheets 15a, 15b and 15c is 50% to 85% or less of the thickness before pressing (for example, 1.1 N / m ² ) I assume. The pressure applied to the legs 14a and 14b is loaded, for example, by a universal strength tester at 0.1 N / mm ² using an indenter of φ1.3.

  Subsequently, while the adhesive sheet 15a is crushed, the sheet 20aS is wound by a predetermined number of plies so as to surround the outer peripheral surface of the leg portion 14a and the main rod 3. Similarly, the sheet 20bS is wound by a predetermined number of plies so as to surround the leg portion 14b and the outer peripheral surface of the main rod 3 while the adhesive sheet 15b is crushed.

  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 core 3. By curing the sheets 20aS and 20bS in this manner, the fixed layers 20a and 20b are formed. The reel sheet 10 is fixed to the core 3 by the first fixing layers 20a and 20b.

  The heating of the wound body can be performed using a known heating furnace. For example, by placing the wound body in a heating furnace maintained at a predetermined temperature for a predetermined time, heating necessary for obtaining the fixed layers 20a and 20b is performed on the wound body. During heating of the wound body, a tightening tape may be wound around the wound body so that the sheets 20aS and 20bS wound around the core 3 do not move during heating.

  The wound body is taken out of the heating furnace after heating, and cooled at room temperature for a predetermined time. After the wound body is sufficiently cooled, the coating layer 30a is formed to cover the fixed layer 20a formed on the wound body, and the coating layer 30b is formed 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. The resin composition is cured by heating or UV irradiation.

  According to the above-described embodiment, since the reel sheet 10 is attached to the former 3 by the adhesive tapes 15a and 15b, the legs 14a and 14b of the reel sheet 10 are removed from the housing even if the former 3 is bent. It can prevent rising.

  Even when a force in the twisting direction acts on the legs 14a and 14b of the reel sheet 10 from the reel R at the time of casting, the adhesive sheets 15a and 15b have a thickness of 0.25 mm or more. The twisting force acting on the legs 14a and 14b of the reel sheet 10 can be buffered by 15b.

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

  As described above, by attaching the reel sheet 10 to the former 3 via the adhesive sheets 15a and 15b, the former 3 is bent and the leg portions 14a and 14b of the reel sheet 10 have a force in the direction of rising from the former 3 Even when it acts, even when a force in the twisting direction acts on the reel sheet 10, it is possible to prevent the reel sheet 10 from peeling off from the main reed 3.
