Description

  The present invention relates to an improvement of a fishing rod.

A cylindrical reel sheet may be used in a fishing rod that uses a reel, and a metal reel sheet is mounted particularly in a fishing rod for large fishing. For example, in a configuration in which the bag main body is detachably attached to a grip body having a cylindrical reel sheet, a blank butt portion is inserted and fixed to the ferrule, and the ferrule is inserted and fixed to the reel sheet .

By the way, there is a case where importance is attached to the characteristic that the fishing rod is bent to the bat. In particular, in a fishing rod for large fishing, importance is attached to the characteristic of bending to the bat, and the fishing rod is bent to cope with the pulling of the big fish. Such fishing rods are usually solid (solid) blanks. However, when the blank is made of a solid structure, it has a demerit that it is heavy although it has excellent bending characteristics. Therefore, when the inventor manufactured a hollow blank and conducted a bending test in order to reduce the weight, it was found that the blank breaks and breaks in a state different from a normal state in the vicinity of the front end of the ferrule. Usually, when such a bending test is performed, the result is that the reinforcing fibers such as carbon fibers aligned in the axial direction of the ridges used in the blank break without being able to withstand the tensile stress on the outside of the bent shape, The phenomenon that the blank breaks occurs. However, in the bending test, the blank was damaged so as to be crushed radially inward in the vicinity of the front end of the ferrule. This means that the blanks were not broken as a result of the reinforcing fibers aligned in the axial direction of the ridge reaching the limit of tensile stress, but were broken by some other factor .

Therefore the present invention is the made in view of the conventional problems, and aims to prevent the collapse bending phenomenon of the blank in the vicinity of the front end of the ferrule in the fishing rod having a large bend characteristic to the butt portion.

The present invention has been made to solve the above-mentioned problems, and a fishing rod according to the present invention includes a rod main body in which a ferrule is mounted outside a rear end portion of a blank having a hollow bat portion , and the rod main body. In a fishing rod having a grip body with a cylindrical reel seat that is detachably connected to the rear side and into which a ferrule of the rod main body is inserted, a core material having a predetermined length inside the bat portion of the blank Is inserted, and the core member protrudes to the front side of the front end of the ferrule with a protruding length of 100 mm or less, or the position of the front end of the core member is substantially coincident with the position of the front end of the ferrule. Features.

In the fishing rod having such a configuration, a core material is inserted inside the bat portion of the blank, and the core material projects with a projecting length of 100 mm or less in front of the front end of the ferrule , or the core material Since the position of the front end of the ferrule substantially coincides with the position of the front end of the ferrule , when the blank is bent to the butt portion, the bat portion of the blank is supported from the inside by the core material in the vicinity of the front end of the ferrule . In addition, since the front end of the core material is within 100 mm in front of the front end of the ferrule , there is substantially no effect on the bending of the blank, and an increase in weight due to insertion of the core material is suppressed.

In particular, it is preferable that the rear end of the core material is substantially flush with the rear end of the blank. When the core material is inserted from the rear end of the blank, the core material can be easily inserted to a predetermined position. Therefore, the position variation of the core material is reduced, and the core material can be reliably positioned in the vicinity of the front end of the ferrule without excessively increasing the length of the core material.

Further, it is preferable that a reinforcing layer having a reinforcing fiber in the circumferential direction is locally formed only in a predetermined length range in the butt portion of the blank, and the core material is contained in the forming range of the reinforcing layer. Thus, by locally forming the reinforcing layer only in a predetermined length range instead of the entire length of the blank, an increase in the weight of the blank can be suppressed, and the core material is inserted and arranged so as to fit in the forming range of the reinforcing layer. If this is the case, it is possible to more reliably prevent the blank from being crushed and damaged near the front end of the ferrule by the synergistic effect of the reinforcing layer and the core material.

  The core material may be hollow, but is preferably made of a solid fiber reinforced resin. When the core is made of solid fiber reinforced resin, the bat portion of the blank can be effectively reinforced from the inside.

In that case, the reinforcing fiber of the core material is preferably a glass fiber. Since glass fiber is more viscous than carbon fiber, it can smoothly follow the bending of the bat portion of the blank. Therefore, it is particularly effective in a configuration in which the core member protrudes forward by a predetermined length from the front end of the ferrule .

As described above, the core material of a predetermined length is arranged at a predetermined position inside the butt portion of the blank, thereby suppressing the increase in weight and maintaining the merit that the majority is hollow and lightweight. It is possible to prevent the blank from being collapsed near the front end of the cable.

Sectional drawing containing the partially broken line which shows the principal part of the fishing rod in one Embodiment of this invention. Sectional drawing of the principal part of the rod main body of the fishing rod in the same embodiment.

  Hereinafter, a fishing rod according to an embodiment of the present invention will be described with reference to the drawings. First, the principal part of the whole structure of the fishing rod in this embodiment is shown in FIG. The fishing rod includes a rod body 1 and a grip body 2, and the rod body 1 is configured to be detachable from the grip body 2.

  FIG. 2 shows a main part of the bag main body 1 in a state removed from the grip body 2. The heel body 1 is configured to have one or a plurality of blanks 10, and is preferably a one-piece rod composed of one blank 10. Hereinafter, a one-piece rod will be described as an example. That is, the heel body 1 includes a hollow blank 10, a ferrule 11 bonded and fixed to the butt portion of the blank 10, and a fastening nut 12 for fixing the heel body 1 to the grip body 2. For example, in the structure in which the ridge body 1 has two blanks 10, the blank 10 on the heel side is at least hollow.

  The blank 10 is made of a hollow fiber reinforced resin, and is formed into a hollow shape by winding a prepreg around a mandrel and heating and firing. Carbon fibers, glass fibers, and the like are used as the prepreg reinforcing fibers. In particular, it is preferable to use both carbon fiber and glass fiber. In addition, it is preferable to use a prepreg in which reinforcing fibers are aligned in the axial direction of the ridge as the prepreg (main pattern) for constituting the main layer of the blank 10. In particular, the reinforcing fiber is preferably a glass fiber, and particularly preferably a UD glass, because it is easy to obtain a characteristic of being bent and greatly bent. In addition, it is preferable to provide an outer layer and an inner layer formed by spirally winding a tape-shaped prepreg in which carbon fibers are used on the outer side and the inner side of the main layer, respectively.

  Moreover, it is preferable that the innermost layer of the blank 10 is configured, and the reinforcing layer 14 is formed only in a predetermined length range from the rear end of the entire length of the blank 10. The formation range of the reinforcing layer 14 is indicated by a symbol S in FIG. The total length of the reinforcing layer 14 is at least longer than the total length of the flange mounting hole 15 of the ferrule 11 and longer than the core member 13 described later, specifically, about 100 to 300 mm. The reinforcing layer 14 is preferably formed from a prepreg in which reinforcing fibers are aligned in the circumferential direction. The reinforcing layer 14 is preferably formed in the innermost layer, but may be formed outside the inner layer, for example.

  Further, a core member 13 is inserted and fixed inside the bat portion of the blank 10. The outer diameter of the core material 13 is substantially equal to the inner diameter of the rear end portion of the blank 10. Therefore, the core material 13 is inserted inside the blank 10 with substantially no gap and fixed by an adhesive. The core material 13 is considerably shorter than the entire length (for example, 1.5 m to 3 m) of the blank 10 and has a length of about 50 mm to 200 mm, for example. The core material 13 reaches the rear end of the blank 10, and therefore the rear end of the core material 13 is substantially flush with the rear end of the blank 10. On the other hand, the position of the front end 13 a of the core member 13 is on the front side of the position of the front end 11 a of the ferrule 11, and thus the core member 13 protrudes to the front side of the ferrule 11 by a predetermined length. The projecting length of the core member 13 projecting forward from the ferrule 11 is indicated by the symbol PL in FIG. The protruding length of the core 13 protruding from the ferrule 11 is within 100 mm, preferably within 50 mm, and more preferably within 30 mm. In addition, the position of the front end 13a of the core member 13 is the rear side of the position of the front end 14a of the reinforcing layer 14 of the blank 10, and therefore the length of the core member 13 is shorter than the length of the reinforcing layer 14 of the blank 10, The core material 13 is inserted so as to be within the formation range of the reinforcing layer 14.

  The core material 13 is made of a solid fiber reinforced resin. The reinforcing fiber may be various fibers such as carbon fiber and glass fiber, and glass fiber is particularly preferable. In addition, it is preferable that a chamfered portion is formed on the peripheral edge portion of the front end surface of the core member 13 to facilitate insertion into the blank 10.

  The ferrule 11 is mounted and fixed on the outside of the rear end portion of the blank 10 configured as described above. The ferrule 11 is made of a metal such as aluminum or stainless steel or a hard resin. The ferrule 11 has a cylindrical shape with a front end opening and a rear end closing. Therefore, the ferrule 11 has the flange attachment hole 15 opened to the front side, and the rear end portion of the blank 10 is inserted and fixed to the flange attachment hole 15. The ferrule 11 is divided into an insertion part 16 to be inserted into a reel sheet (to be described later) of the grip body 2 and a protrusion part 17 that protrudes forward from the reel sheet when the insertion part 16 is inserted into the reel sheet. The insertion part 16 of the ferrule 11 is longer than the protrusion part 17, and its outer diameter is substantially constant and substantially equal to the inner diameter of the reel sheet. An engagement groove 18 extending in the radial direction is formed on the rear end surface of the insertion portion 16, that is, the rear end surface of the ferrule 11. The engagement groove 18 has, for example, a V shape, and engages with the engagement pin 24 of the grip body 2 as shown in FIG. In this way, the engagement groove 18 on the rear end face of the ferrule 11 is engaged with the engagement pin 24 of the grip body 2, whereby the collar body 1 is positioned in the circumferential direction with respect to the grip body 2, and the relative axis is rotated. Is prevented from rotating. That is, the engaging groove 18 of the ferrule 11 and the engaging pin 24 of the grip body 2 exhibit a function of preventing rotation. The protruding portion 17 located on the front side of the insertion portion 16 is formed thicker than the insertion portion 16, and a flange portion 19 is formed in an annular shape at the rear end portion. As shown in FIG. 1, the flange portion 19 abuts against the front end surface of the reel sheet when the bag body 1 is attached to the grip body 2. A packing may be interposed between the flange portion 19 and the front end surface of the reel sheet.

  A fastening nut 12 is rotatably mounted on the outside of the protrusion 17 of the ferrule 11. The fastening nut 12 is prevented from moving to the rear side by the flange portion 19 of the ferrule 11, and the female screw portion 12a formed on the inner peripheral surface of the rear portion is screwed into the male screw portion 26 of the reel sheet. The flange portion 19 of the ferrule 11 is pressed backward to connect and integrate the heel body 1 and the grip body 2.

  The grip body 2 is detachably connected to the rear side of the bag body 1. The grip body 2 includes a cylindrical reel sheet, also called a pipe sheet, and a grip 20 located on the rear side of the reel sheet. The reel sheet includes a cylindrical reel sheet main body 21 into which the ferrule 11 is inserted, and a pair of front and rear hoods 22 and 23 that hold the leg portions F of the reel. As with the ferrule 11, the reel sheet main body 21 is made of metal or hard resin. The engaging pin 24 described above is attached to the reel sheet main body 21. In addition, one of the pair of front and rear hoods 22 and 23 is movable in the axial direction with respect to the reel seat body 21 and the other is not movable. In this embodiment, the front hood 22 is a movable type and the rear side. The hood 23 is a fixed type. In order to fix the position of the movable front hood 22, a fixing nut 25 is doubled on the front side, and the fixing nut 25 is screwed into the male thread portion 26 of the reel seat body 21. ing. In the present embodiment, a so-called double nut structure is provided in which a pair of fixing nuts 25 are provided at the front and back, but a so-called single nut structure in which only one fixing nut 25 is provided may be used. The grip 20 is made of EVA or cork, and a front end portion thereof is inserted and fixed to the inside of the reel sheet main body 21 or is externally attached and fixed to the outside of the reel sheet main body 21.

  In the fishing rod configured as described above, the core member 13 is inserted inside the blank 10 and the core member 13 is located inside the position of the front end 11 a of the ferrule 11. The blank 10 is supported from the inner side by the core member 13 in the vicinity of the front end 11a of the ferrule 11 even when it is bent to the butt portion. Therefore, the collapse of the blank 10 in the vicinity of the front end 11a of the ferrule 11 is reliably prevented. Moreover, since the collapse of the blank 10 is prevented, the tone can be set so that the blank 10 is bent in an arc when the fish is caught, and the interaction with the fish can be enjoyed. Further, in large fishing, it is possible to easily cope with fish pulling due to its bending characteristics.

  In particular, since the core member 13 projects forward from the front end 11 a of the ferrule 11, it is possible to reliably prevent the blank 10 from being crushed at a location immediately before the ferrule 11. In addition, since the protruding length is a limited length of 100 mm or less, the original tone of the blank 10 is not impaired, and the tone of bending to the butt portion can be maintained. Furthermore, since most of the blank 10 remains hollow, it is sufficiently light compared to the case where the blank 10 is a solid solid body, and a light fishing rod that secures a large bending characteristic. Good operability peculiar to can be secured.

  Moreover, since the core member 13 is made of a solid fiber reinforced resin, the blank 10 can be effectively reinforced from the inside, and the collapse of the blank 10 can be further reliably prevented. In addition, when the reinforcing fiber of the core material 13 is a glass fiber, the influence on the bending of the butt portion of the blank 10 can be reduced.

  On the other hand, since the rear end of the core member 13 is substantially flush with the rear end of the bag main body 1, the core member 13 is easily inserted to a predetermined position when the core member 13 is inserted from the rear end of the bag main body 1. The assembly workability is excellent. As a result, the position variation of the core material 13 is reduced, and the core material 13 can be surely positioned at a predetermined position as designed with respect to the ferrule 11, and the length of the core material 13 is considered in consideration of the position variation. There is no need to make it too long.

  Further, if the reinforcing layer 14 is locally formed in the bat portion of the blank 10 within a predetermined formation range, the weight of the blank 10 is increased as compared with the case where the reinforcing layer 14 is formed over the entire length of the blank 10. While being able to suppress, the blank 10 in the front end 11a vicinity of the ferrule 11 can be effectively reinforced. Further, since the reinforcing layer 14 is formed only in a predetermined range of the butt portion, the influence on the overall tone of the blank 10 can be minimized. And since the core material 13 is inserted so as to fit in the formation range of the reinforcing layer 14, the synergistic effect of the reinforcing layer 14 and the core material 13 effectively prevents the blank 10 from collapsing in the vicinity of the front end 11 a of the ferrule 11. Can be suppressed. In particular, since the reinforcing fibers that constitute the reinforcing layer 14 are along the circumferential direction, the reinforcing layer 14 effectively acts against collapse. Further, since the core material 13 is within the formation range of the reinforcing layer 14, the blank 10 is effectively reinforced by the reinforcing layer 14 even in the vicinity of the front end 13 a of the core material 13. Moreover, since the reinforcing layer 14 extends longer to the front side than the core material 13, the portion of the blank 10 immediately in front of the core material 13 is reinforced by the reinforcing layer 14, and the strength of the blank 10 at that portion can be sufficiently secured. .

  In the present embodiment, the core member 13 protrudes to the front side of the ferrule 11 with a predetermined protrusion length. However, the core member 13 may not substantially protrude to the front side of the ferrule 11. The position of the front end 13 a of 13 may substantially coincide with the position of the front end 11 a of the ferrule 11.

  Moreover, it is good also as a structure which attached the cylinder body made from resin (for example, product made from fiber reinforced resin) to the inner peripheral surface of the reel sheet | seat main body 21, and extended | stretched back the cylinder body so that the grip 20 might be attached to the outer side. Also good.
