Description

  The present invention relates to a fishing rod, and in particular, a fishing rod that has a bottom plug member disposed at the rear end portion of the main rod and prevents the middle rod housed in a swingable manner from the front end portion from falling off from the rear end portion of the main rod. About.

  Generally, a swing-type fishing rod has a tail plug member disposed at the rear end of a large-diameter main rod to prevent the tip-side middle rod and the tip rod formed in order from a small diameter from falling off the rear end. It has a compact structure housed inside. When using, the tip and middle hooks are pulled out from the tip of the main shaft, and the end of the adjacent large-diameter rod and the rear end of the small-diameter rod are fitted to each other to connect the joint portion. Form a long fishing rod. When cleaning a small-diameter soot tube stored in such a large-diameter main shaft, the small-diameter soot tube stored inside is pulled out from the rear end of the main shaft by removing the bottom plug member.

In such a fishing rod, a concave portion is formed on the rear side of the bottom plug member made of a soft material such as rubber, and a reinforcing member made of a hard material such as metal is inserted into the concave portion, so that an appropriate elasticity is applied to the end surface. Has been developed to improve operability and prevent damage (for example, see Patent Document 1).
JP 2000-41542 A

  However, since the reinforcing member is supported by a bottom plug member made of a soft material, for example, even when fixed with an adhesive, there is a large difference in the amount of deformation when a force is applied. With use over a period of time, the reinforcing member may fall off. When the reinforcing member falls off, the bottom plug member is easily deformed and the operability is lowered.

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing rod that can maintain an initial state over a long period of time and maintain a suitable operability.

The fishing rod of the present invention that achieves the above object has a bottom plug member disposed at the rear end portion of the main rod, and prevents the middle rod stored so as to be able to swing out from the front end portion from falling off from the rear end portion of the main rod. A fishing rod that
The bottom plug member is made of a hard material having a body portion fixed to the rear end portion of the main shaft and a flange-like portion that protrudes from the rear end portion of the body portion toward the inner peripheral side to form an axial through hole. Bottom plug ring, front wall portion and rear wall portion engaged with the front end side and rear end side end surface of the hook-shaped portion of the bottom plug ring, and the front wall portion and the rear wall portion inserted through the through hole. A bottom plug cap made of a soft material having a connecting portion that is integrally connected, and the bottom plug ring is fitted into the rear wall portion of the bottom plug cap from the rear end side end surface of the hook-shaped portion, and this rear wall portion The rear wall portion of the bottom plug cap is formed integrally with a restriction wall portion that regulates deformation of the bottom plug cap, and a plate-like decoration that is harder than the bottom plug cap is formed in the hollow portion. The member is arranged.

  The front wall portion of the bottom plug cap has an outer diameter larger than the outer diameter of the rear end portion of the largest inner rib among the inner ribs housed in the main rod, It is preferable to have a diameter smaller than the outer diameter of the rear end portion of the middle diameter of the maximum diameter.

  In addition, the rear wall portion of the bottom plug cap is formed with an annular groove on the bottom wall side of the recess portion, which is formed with the outer peripheral edge portion of the plate-shaped decorative member, on the peripheral wall forming the recess portion. Is preferably arranged at the same or the front of the rear end of the regulating wall along the axial direction.

  The rear end portion of the plate-shaped decorative member is preferably disposed in front of the rear end portion of the butt plug cap, and the front wall portion of the butt plug cap has a through hole in the hook-shaped portion. It is preferable to occlude.

  According to the fishing rod of the present invention, since the deformation of the rear wall portion of the bottom plug cap made of the soft material is restricted by the restriction wall portion formed integrally with the bottom plug ring made of the hard material, the rear wall of the bottom plug cap. The plate-shaped decorative member arranged in the hollow portion of the portion is difficult to drop off from the bottom plug cap, and suitable operability can be maintained over a long period of time.

  If the front wall of the bottom plug cap is formed with a diameter larger than the center diameter of the maximum diameter and the through hole of the bottom plug ring is formed with a diameter smaller than the center diameter of the maximum diameter, When storing the heel, the inner diameter of the largest diameter where the greatest impact is applied abuts against the front wall of the soft cap cap, so the flexible front wall reduces the impact and reduces this force. Transmit to the butt plug ring. For this reason, a large impact does not act on the bottom plug ring, the rear wall portion of the bottom plug cap is prevented from being deformed, and the plate-shaped decorative member is prevented from falling off.

  When the annular groove for holding the plate-shaped decorative member is disposed in the recess formed in the rear wall portion of the bottom plug cap at the same position as or in front of the rear end portion of the restriction wall portion, The bottom plug cap is not easily deformed with respect to the ring. Therefore, even if an external force acts on the bottom plug cap, the regulating wall supports this force and hardly acts on the plate-shaped decorative member. Dropout is suppressed.

  When the rear end portion of the plate-shaped decorative member is disposed in front of the rear end portion of the bottom plug cap, even if the rear end portion of the fishing rod is abutted against the ground or the like, The plate-like decorative member held on the rear wall portion is unlikely to fall off from the bottom plug cap because the scratches are difficult to occur and no external force is transmitted to the rear wall portion.

  In addition, when the front wall portion of the butt plug cap closes the through hole of the bowl-shaped portion, water does not flow into the recessed portion through the through-hole, and the front wall portion is temporarily removed from the bowl-shaped portion. Even in the case of peeling, water is prevented from flowing into the peripheral portion of the plate-shaped decorative member. For this reason, it is suppressed that a plate-shaped decorative member falls off from the bottom plug cap.

FIG. 1 shows the rear end of a fishing rod 10 according to a preferred embodiment of the present invention.
As shown in FIG. 1, the fishing rod 10 according to the present embodiment has a bottom plug member 14 disposed at the rear end portion of the largest diameter main rod 12, and the first, second, and third portions are sequentially formed in a large diameter. It is formed in a swing-out type in which the middle collars 8a, 8b, and 8c are housed together with a spike basket (not shown). Together with the spike head, these center rods 8a, 8b, 8c are swung out from the front end portion of the main rod 12, and the corresponding ends of the adjacent center rods 8a, 8b, 8c along the axial direction are fitted together and joined together. By forming the joint, it can be used as a long fishing rod 10. Each of the steel pipes that form the base iron 12 and the intermediate irons 8a, 8b, and 8c is formed by winding a fiber reinforced prepreg (FRP) in which a reinforcing fiber is impregnated with a synthetic resin around a core metal, and then curing, decentering, etc. It is formed through the usual process.

  The number of intermediate braces between these genital warps 12 and the head spears not shown is not limited to the above three. Further, for example, the second and third center rods 8b and 8c may be omitted, and the first center rod 8a on the tip side or the tip rod itself may be joined to the base rod 12. Further, a side-by-side structure such as a side-by-side connection between the main bar 12 and the third largest center bar 8c having the largest diameter may be adopted. It is also possible to form

  In addition to the main body prepreg extending over the entire length of the main rod 12, the rear end portion of the main rod 12 is formed in a thicker structure than the intermediate portion by an appropriate narrow reinforcing prepreg, and the rear end portion is strengthened. ing. In addition, such a reinforced prepreg is attached to the main body prepreg and wound, and the main body prepreg and the reinforcing prepreg are alternately arranged, thereby reducing the step between the main body prepreg and suppressing the generation of wrinkles. Is possible. In particular, at the rear end portion, it is preferable to arrange a prepreg in which the reinforcing fibers are aligned in the circumferential direction so that the reinforcing fibers in the prepreg are not broken as much as possible when a screw described later is formed. The base rod 12 formed in this way is preferably formed to a thickness of about 1 mm, for example, and even when the internal thread 16 is formed, it is preferable to maintain sufficient strength at the rear end portion.

In the fishing rod 10 of the present embodiment, the bottom plug member 14 is screwed into the female screw 16 formed at the rear end portion of the main rod 12.
As shown in FIGS. 1 to 4, the bottom plug member 14 includes a bottom plug ring 18 formed of a hard material and a bottom plug cap 20 formed of a soft material. The material forming the bottom plug ring 18 is, for example, a hard material that does not deform when gripped with a finger, including a metal such as aluminum alloy, stainless steel, brass, or titanium alloy, or a hard resin such as ABS or polyamide. Preferably, the soft material forming the butt plug cap 20 includes, for example, natural rubber, synthetic rubber, elastomer, and the like, and is preferably a material that gives a soft feeling to the fingers to be gripped. Both are excellent in corrosion resistance and are preferably lightweight materials.

  The bottom plug ring 18 includes a barrel portion 22 fixed to the rear end portion of the main rod 12, and a hook-like portion 26 that protrudes from the rear end portion of the trunk portion 22 to the inner peripheral side to form an axial through hole 24. A male screw 28 that is screwed into the female screw 16 of the main shaft 12 is formed on the outer peripheral portion of the body portion 22. At the rear end portion of the body portion 22, a ridge 30 is extended over the entire circumference, and a knurled anti-slip 30 a is formed on the outer peripheral surface of the ridge 30. A groove 34 that accommodates an O-ring 32 (see FIG. 1) is formed between the protrusion 30 and the male screw 28 so as to open outward, and the bottom plug member 14 is screwed to the main rod 12. At this time, the O-ring 32 is preferably pressed between the rear end surface of the main bar 12 and the ridge 30 to seal between the main bar 12 and the buttocks plug member 14, and the The plug member 14 is prevented from loosening. As long as this O-ring 32 can perform such a sealing action and a loosening prevention action, other than the above, for example, the O-ring 32 is disposed between the inner circumferential surface of the main shaft 12 and the outer circumferential surface of the trunk portion 22. May be.

  Further, a cylindrical wall portion 36 projects rearward from the rear end surface of the flange-like portion 26 on the bottom plug ring 18, and an annular rib 38 is radially outwardly extended from the rear end portion of the wall portion 36. Protruding. The cylindrical wall portion 36 is disposed at a substantially intermediate position between the through hole 24 and the protrusion 30, and the outer edge portion of the annular rib 38 is on the inner peripheral side of the protrusion 30, and the inner periphery of the trunk portion 22. It is preferable to arrange it radially inward from the surface. As will be described later, these wall portions 36 and ribs 38 form a restriction wall portion that restricts deformation or material movement of the bottom plug cap 20.

  As shown in FIGS. 3 and 4, the bottom plug cap 20 attached to the bottom plug ring 18 includes a front wall portion 40 that engages with a front end side and a rear end side end surface of the hook-shaped portion 26 of the bottom plug ring 18. The rear wall portion 42 has a connecting portion 44 that is inserted through the through hole 24 of the bottom plug ring 18 and integrally connects the front wall portion 40 and the rear wall portion 42, and is integrally formed with the bottom plug ring 18. Alternatively, they are integrated with, for example, an adhesive. Therefore, the bottom plug cap 20 is not easily detached from the bottom plug ring 18. The connecting portion 44 of the present embodiment is formed in an annular structure having a lightening hole 43 at the center, but it is also possible to omit such a lightening hole 43 and form a thick disk. is there.

  The front wall portion 40 of the bottom plug cap 20 has an outer diameter formed to be equal to or larger than the outer diameter of the largest inner collar 8c (see FIG. 1) and a thickness of about 2 mm, for example, within a range of 1 to 3 mm. The impact when the intermediate collars 8a to 8c come into contact with each other can be reduced. Further, a gap may be formed between the inner peripheral surface of the trunk portion 22. The inner peripheral side of the front wall portion 40 extends beyond the connecting portion 44 and continues to the closing portion 41 that closes the through hole 24. As shown in the figure, the blocking portion 41 is not the same thickness as the front wall portion 40, and may be formed thicker or thinner than this. The bottom plug member 14 can be reduced in weight by making it thinner.

  Similar to the front wall portion 40, the rear wall portion 42 of the bottom plug cap 20 is integrated with the rear end surface of the flange-shaped portion 26, and has a cylindrical wall portion 36 protruding from the rear end surface of the flange-shaped portion 26 and The rib 38 is fitted into the rear wall portion 42. The rear wall portion 42 has a wall thickness and an outer diameter that allow the wall portion 36 and the rib 38 to be housed in an embedded state without protruding from the outer surface. The outer peripheral surface of the rear wall portion 42 is arranged to be the same as the outer peripheral surface of the ridge 30 or slightly inward from the outer peripheral surface, and through a slip stopper 30a formed on the outer peripheral surface of the ridge 30. The bottom plug member 14 can be operated. In addition, a rounded curved surface 44a is formed on the rear end side edge of the rear wall portion 42, and there is no corner that hits the hand when operating, and it can be gripped and operated smoothly. .

The rear wall portion 42 thus formed is formed with a recess 46 that opens rearward. In the recess portion 46 includes an annular bottom wall 45 formed at the rear surface of the connecting portion 44 described above, and preferably the peripheral wall 47 of a smaller diameter than and the wall portion 36 is larger in diameter than the transmural hole 24 An annular groove 50 is formed in a portion adjacent to the bottom wall 45 of the peripheral wall 47 and opening radially inward. The axial position of the annular groove 50 is preferably substantially the same as that of the rib 38, or is preferably located in front of the rib 38, that is, in the cylindrical wall portion 38.

  As shown in FIGS. 5 and 6, a plate-like decorative member 52 is accommodated in a recess 46 formed in the rear wall portion 42 and placed on the bottom wall 45, and its outer peripheral portion is fitted in the annular groove 50. Combined. The plate-like decorative member 52 is formed of a harder material than the bottom plug cap 20 and increases the rigidity while leaving a suitable elasticity on the rear end surface of the bottom plug cap 20 to form a suitable operability.

  The plate-like decorative member 52 is formed on a rear end surface of a disk-like main body portion 54 formed of a metal material such as an aluminum alloy, or a hard resin material such as ABS or polyamide, with a symbol A in FIG. , B, and C (for example, letters, symbols, designs, etc.) are applied, and a transparent resin 56 such as epoxy or urethane is potted. Thus, when potting the transparent resin 56, the decoration of the main body 54 is clearly emphasized by the lens effect of the transparent resin 56. Instead of this, the plate-like decorative member 52 may be integrally formed of a hard member.

  The plate-shaped decorative member 52 is mounted in the recess 46 in a state where the outer peripheral portion is fitted in the annular groove 50 and is fixed to the bottom wall 45 with a double-sided tape or an adhesive. The decorative member 52 is structurally coupled with the outer periphery of the annular groove 50 and is physically coupled to the bottom wall 45, whereby it is difficult to fall off from the buttock cap 20, and the butt plug is extended over a long period of time. The initial state of the member 14 can be maintained.

  Further, the plate-like decorative member 52 holds the rear end surface thereof in the axial direction forward from the rear end portion of the bottom plug cap 20, that is, in the recess portion 46 without protruding rearward from the recess portion 46. Thus, for example, even when the rod end of the fishing rod 10 protrudes from the ground, the plate-shaped decorative member 52 can be maintained in its initial state for a long period of time without dropping from the recess 46 or scratching the rear end face. Can do.

  The bottom plug member 14 formed in this way is removed from the rear end portion of the main rod 12 when performing maintenance such as extracting and cleaning the middle rods 8a to 8c from the main rod 12. At this time, a large external force acts on the bottom plug cap 20 of the bottom plug member 14. Of the external force acting on the rear wall portion 42 of the butt plug cap 20, the circumferential or radial force is supported by the cylindrical wall portion 36 extending rearward, and the axial force is applied to the wall portion 36 of the butt plug ring 18. A rib 38 formed at the rear end portion is supported, whereby the rear wall portion 42 of the bottom plug cap 20 is restricted from being deformed or moved in the axial direction and the circumferential direction. Accordingly, the cylindrical wall portion 36 and the annular rib 38 of the bottom plug ring 18 function as a regulating member that regulates deformation or movement of the rear wall portion 42 of the bottom plug cap 20.

  For this reason, the annular groove 50 for holding the plate-like decorative member 52 in the recess 46 of the bottom plug cap 20 is disposed at the same position as or in front of the restricting wall, that is, the rear end of the wall 36 and the rib 38. In this case, the bottom plug cap 20 is unlikely to be deformed with respect to the bottom plug ring 18. Therefore, even if an external force acts on the bottom plug cap 20, the wall portion 36 and the rib 38 support this force, and the plate shape It hardly acts on the decorative member 52, and the dropping of the plate-shaped decorative member 52 is suppressed.

  In particular, the annular groove 50 that supports the outer peripheral portion of the plate-shaped decorative member 52 is disposed on the inner side of the cylindrical wall portion 36, that is, the same as or in front of the rib 38 in the axial direction, and forms the annular groove 50. When the peripheral wall 47 is formed to have a larger diameter than the through hole 24, even if an external force acts on the rear wall portion 42 of the bottom plug cap 20, the rear wall portion 42 and the annular groove 50 that form the annular groove 50 are The movement or deformation of the wall portion 36 and the rib 38 of the bottom plug ring 18 is restricted, and the plate-like decorative member 52 is prevented from falling off. Furthermore, since the relative movement between the plate-shaped decorative member 52 and the bottom wall 45 is also suppressed, the adhesive force or adhesive force between them is not reduced. The plate-like decorative member 52 is difficult to drop off from the bottom plug cap 20 and the bottom plug member 14 and can maintain a suitable operability over a long period of time.

  Further, the front wall portion 40 of the bottom plug cap 20 has an outer diameter that is greater than or equal to the maximum diameter middle collar 8c, and the through hole 24 of the bottom plug ring 18 is formed to have a smaller diameter than the maximum diameter middle collar 8c. Thus, the maximum diameter of the intermediate collar 8c, which is subjected to the greatest impact when the middle collars 8a to 8c are sequentially stored in the main cage 12, abuts against the front wall 40, so that the flexible front wall 40 is impacted. This force is transmitted to the buttocks plug ring 18 through the hook-like portion 26. Therefore, a large impact does not act on the bottom plug ring 18, the rear wall portion 42 of the bottom plug cap 20 is prevented from being deformed, and the plate-shaped decorative member 52 is prevented from falling off. Here, it is more preferable that the through hole 24 is formed to have a smaller diameter than a plurality of the middle flanges, such as a smaller diameter than the outer diameters of the intermediate collars 8a and 8c as shown in FIG.

  Further, since the front wall portion 40 of the bottom plug cap 20 closes the through hole 24 of the bowl-shaped portion 26, water does not flow into the recessed portion 46 through the through hole 24, and the front wall Even when the part 40 is peeled off from the bowl-like part 26, water is prevented from flowing into the peripheral part of the plate-like decorative member 52. For this reason, it is suppressed that the plate-shaped decorative member 52 falls off from the bottom plug cap 20.

  It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that various modifications can be made within the scope of the claims. For example, the connecting portion 44 of the butt plug cap 20 has a thinned portion 43 formed at the center, but such a thinned portion may be omitted or a plurality of thinned portions may be provided along the circumferential direction. It is.
