BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod formed by connecting a plurality of rods, in particular, a main rod and an upper rod connected to the tip of the rod are connected in a swing-out manner, and the positional relationship of these is adjusted by adjusting the positional relationship between them. The present invention relates to a fishing rod whose length can be adjusted.
[0002]
[Prior art]
In a conventional fishing rod, a plurality of cylindrical rods can be sequentially inserted from the tip-side rod into the rod-side rod. When fishing, each chassis is pulled out to the tip side sequentially and fitted and fixed to be used as a single chassis. On the other hand, at the time of storage, the body on the tip side is sequentially stored in the body on the base side to make it compact.
[0003]
In addition, some conventional fishing rods have been devised so that fishing can be performed by adjusting the length of the entire rod while adjusting the former rod and the rod. The fishing rod of the fishing rod devised in this way has a fitting female part formed on the inner peripheral surface of the tip end side that is formed to have a slightly smaller diameter than the other part and can be fitted to the outer peripheral surface of the proximal side end of the upper upper rod. In addition, a cylindrical member is provided on the inner peripheral surface of the heel side end. In such a fishing rod, when the former upper rod connected to the tip side of the former rod is pulled out to the ear tip side (hereinafter referred to as “stretched state”), the fitting female portion of the former rod is the former upper rod. In the state in which the upper collar is fitted into the outer peripheral surface of the collar and the upper collar is inserted into the former (hereinafter referred to as the “stored state”), the proximal edge of the former collar in which the tubular member is inserted Fits to the outer peripheral surface of the part. In this way, the main rod and the upper rod can be fitted and fixed to each other in either the “stretched state” or the “stored state”, and fishing can be performed by changing the overall length of the rod according to the situation. It becomes.
[0004]
[Problems to be solved by the invention]
This type of fishing rod, in which the total length of the fishing rod can be adjusted by the mutual relationship between the main rod and the former rod, is especially arranged on the inner side of the rod side to improve the mutual fitting force. The diameter is set so that the fitting member to be fitted and the outer diameter of the heel side of the former upper heel accurately match. However, when a fishing rod is used over a long period of time and the fitting between the upper rod and the fitting member is repeated, there is a problem that the fitting force gradually decreases due to mutual wear. Therefore, when such wear progresses, it is conceivable to replace the fitting member with a new one and restore the fitting force.
[0005]
However, since the fitting member is a member for sufficiently fixing the former upper collar to the former collar, the fitting member itself needs to be firmly fixed to the former collar. For this reason, even if it makes it possible to attach and detach the fitting member from the main bar and make it replaceable, it is necessary to sufficiently secure the fitting force of the fitting member to the main bar. In addition, it is complicated to remove the fitting member inserted into the cylindrical base rod, and it is necessary to easily remove the fitting member so that the fitting member can be detached.
[0006]
An object of the present invention is to provide a fishing rod that can easily maintain the fitting force between the rods over a long period of time while adjusting the overall length of the fishing rod.
[0007]
[Means for Solving the Problems]
The fishing rod of the first aspect of the present invention is a fishing rod used for fishing by connecting a plurality of tapered cylindrical rods, and an internal thread portion is formed on the inner peripheral surface of the base end portion, and a peripheral surface on the tip side of the internal thread portion is circumferential. A marshall having a fixing hole penetrating the surface, an upper arm connected in a swinging manner to the head side of the head, a fitting member that can be attached to and detached from the inner side of the head of the female screw portion, And a bottom plug attached to the female screw portion. The fitting member is a substantially cylindrical mold member having a split formed continuously in the axial direction, and has a protrusion on the outer peripheral surface that can be inserted into the fixing hole. The inner peripheral surface has a fitting surface that can be fitted.
[0008]
In this fishing rod, the former upper rod is pulled and attached to the tip of the former rod (stretched state), and the former upper rod is housed in the former rod (stored state). , The overall length of the fishing rod can be adjusted. Specifically, in the stretched state, the former upper rod is pulled out toward the tip of the former rod, and the outer peripheral surface of the former upper rod is located on the inner periphery of the tip end of the former rod in the same manner as a normal fishing rod. To fit. On the other hand, in the stowed state, the upper collar is accommodated in the inner collar, and the collar-side end portion of the upper collar is inserted into and fitted into the fitting member of the former collar.
[0009]
Here, the fitting member can be easily attached and detached by the following method. When the fitting member is used for a long time and the fitting force of the fitting member is reduced, the fitting member can be easily replaced. That is, the fitting member has a split in the axial direction, and the diameter can be reduced by this split, and the base member with the diameter reduced from the base side of the base with the bottom plug removed. Is inserted inside. When the fitting member is made free at a predetermined position, the fitting member spreads outward in the radial direction due to the elasticity of the material of the fitting member itself, the protrusion is inserted into the fixing hole, and the fitting member is placed at the predetermined position of the main shaft. It will be fixed. By fitting the protrusion into the fixing hole, the fitting member is sufficiently fixed to the main shaft in both the axial direction and the circumferential direction. On the other hand, when removing the fitting member, the projection is pushed inward in the radial direction from the fixing hole to reduce the diameter of the fitting member, and the fitting member is removed from the base side.
[0010]
The fishing rod of the invention 2 is the fishing rod of the invention 1, and has a plurality of projecting portions projecting in the radially inward direction extending in the axial direction at intervals in the circumferential direction on the inner peripheral surface of the fitting member.
In this fishing rod, there are a plurality of protruding portions on the inner peripheral surface of the fitting member, the contact area when the inner peripheral surface of the fitting member is fitted to the original upper rod is reduced, and mutual sticking is suppressed.
[0011]

As shown in FIG. 1, the punch through which one embodiment of the present invention is used is a marshal 1, a former upper 2 connected to the tip of the former 1, and a tip of the former 2 It has a connected middle collar 3 and a tip collar 4 coupled to the tip side of the middle collar 3. These base rods 1 to 4 are tapered cylindrical members formed from prepregs in which carbon fibers or glass fibers are impregnated with a synthetic resin. Then, the upper heel 2 to the tip heel 4 are sequentially inserted into and removed from the pod on the heel side from the tip side, and are connected in a so-called swing-out manner. Note that the number of rods is set as appropriate depending on the length of the entire fishing rod required, and is not limited to four as described above, and any number can be used.
[0012]
The main rod 1 has a reel sheet 5 formed on the outer peripheral surface to which a reel (not shown) can be detachably attached, and a tail plug 10 is detachably attached to the end portion on the heel side. Further, a fishing line introduction port 6 for introducing the fishing line from the reel into the inside of the rod body is formed on the outer peripheral surface on the tip side, and a fishing line guide 7 is disposed so as to cover the fishing line introduction port 6. It is fixed on its peripheral surface. The inside of each of the rods of the former rod 2 to the tip rod 4 is a fishing line passage, and a fishing line support protrusion is continuously formed in a spiral shape in the axial direction on the inner peripheral surface as necessary. A top guide 8 is attached to the tip side end of the tip rod 4, and the fishing line from the reel is guided to the fishing line passage from the fishing line introduction port 6 through the fishing line guide 7 and from the top guide 8 of the tip rod 4. It will be guided to the outside.
[0013]
In this through-hole, the upper arm 2 and the main shaft 1 can be fixed to each other in both the extended state and the stored state. Below, the structure of the main fence 1 is shown in detail. As shown in FIG. 2 and FIG. 4, the base rod 1 is a cylindrical body with a slightly tapered taper, and the inner peripheral surface of the tip side end portion is a fitting female that fits on the below-mentioned base rod 2. Has become a department. A female thread portion 1a is formed on the inner peripheral surface of the heel side of the heel 1 by directly threading a screw thread on the prepreg material constituting the heel 1, and the butt plug is formed on the female thread 1a. 10 is detachably mounted. A substantially cylindrical fitting member 11 is detachably disposed in the main shaft 1 adjacent to the tip side of the female screw portion 1a. Moreover, the fixing hole 1b is formed in the surrounding surface of the collar side part of the main rod 1 where this fitting member 11 is arrange | positioned.
[0014]
The fitting member 11 is a substantially cylindrical body having a certain degree of elasticity, such as a synthetic resin such as PBT or ABS, or a metal such as aluminum or stainless steel. It has a split 11c formed continuously in the axial direction and is C-shaped in cross section. The inner peripheral surface has a plurality of projecting portions 11b that project in the radially inward direction while extending in the axial direction at intervals in the circumferential direction. It is set to match the outer diameter of the original side end (see FIG. 3). The tip end side of each protruding portion 11b may be chamfered to increase the diameter. On the other hand, a protrusion 11 a that protrudes radially outward is formed on the outer peripheral surface of the fitting member 11. The protrusion 11a is fitted into the fixing hole 1a.
[0015]
The former upper collar 2 is also a cylindrical body with a tapered taper, like the former collar 1. For example, a part of the outer peripheral surface of the heel side end part may be formed with a slightly larger diameter than the other part to form a fitting male part. For example, it can be formed by partially laminating an extra prepreg material, or by setting the diameter so as to partially increase the diameter during surface processing after the housing molding. . The outer diameter of the fitting male part is set so as to match the inner diameter of the fitting female part of the base rod 1 and the inner diameter of the fitting member 12 described above.
[0016]
In a through rod having such a structure, when fishing, the rods are sequentially pulled out toward the tip, and the rods are fitted together in a swing-out manner and used as a single rod. Further, at the time of storage, the attachment of each casing is released, and the tip-side casing is sequentially stored in the casing on the base side to make it compact. Furthermore, in the former fence 1 and the former fence 2, not only the state in which the former upper 2 is pulled out from the former fence 1 (stretched state) but also the state in which it is housed (stored state) is fitted to each other. It is possible to fish while adjusting the overall length of the fishing rod.
[0017]
That is, in the extended state in which the former upper rod 2 is pulled out toward the tip of the former rod 1, the fitting male portion at the end of the upper end of the former upper rod 2 is the former rod 1 like a normal fishing rod. It fits and is fixed with the fitting female part of the inner peripheral surface of the tip. On the other hand, in the storage state in which the former upper collar 2 is inserted into the former collar 1, the fitting male part of the upper upper collar 2 is fitted to the fitting member 11 (see FIG. 3).
When such a fishing rod is used over a long period of time and the fitting between the fitting member 11 and the former rod 2 is repeated, the inner periphery of the fitting member 11, particularly the protruding portion 11 b is worn and gradually fitted. May decrease. In such a case, the fitting member 11 is detached and replaced by the following method.
[0018]
That is, when the fitting member 11 is attached, the bottom plug 10 is removed from the main rod 1, the diameter 11 c is adjusted by narrowing the split 11 c of the fitting member 11, and inserted into the inside of the main rod 1 from the hook side. When the fitting member 11 is made free at a predetermined position, the fitting member 11 spreads outward in the radial direction due to the elasticity of the material of the fitting member 11, and the protrusion 11 a is inserted into the fixing hole 1 b, so that the fitting member 11 is It is fixed at a predetermined position of the main fence 1. On the other hand, when removing the fitting member 11 from the main rod 1, the projection 11 a is pushed inward from the fixing hole 1 b to reduce the diameter of the fitting member 11, and is removed from the base side of the main rod 1.
