Description

FITTING STRUCTURE OF ROD}

The present invention relates to a fitting structure for fitting and fixing two poles connected in a pull-out form.

In the conventional fishing rod, a plurality of cylindrical rods can be inserted into the pole on the proximal side sequentially from the pole on the waterline side. When fishing, each pole is pulled out to the waterline side by side, and fitted with a pole. On the other hand, when storing, the pole on the repair side is sequentially stored in the pole on the proximal side to make it compact.

In addition, the fishing rod of the conventional pull type is designed to be able to fish by changing the length of the entire pole by adjusting the rod (元 上 竿) and the rod (元 竿). The rod of the fishing rod thus devised has a first fitting portion formed on the inner circumferential surface of the repair side end portion that is slightly smaller in diameter than the other portion and can be fitted to the outer circumferential surface of the proximal end of the rod body. It has a 2nd fitting part which is further hardened | cured and can be fitted to the outer peripheral surface of the base end side of a circumference | surroundings also in a base end side end part.

In such a fishing rod, in the state where the original base connected to the repair side of the circle is drawn out to the repair side (hereinafter referred to as an "extended state"), the first fitting portion of the circle fits with the outer peripheral surface of the proximal end of the far end. In a state where the opponent is inserted into the far table (hereinafter referred to as a "storing state"), the second fitting portion of the far end engages with the outer peripheral surface of the base end side of the far end where the far end is inserted. In this way, the far-end and the far-end can be fixed to each other in the state of "extended state" and "in storage", and the fishing rod can be changed by changing the length of the whole pole according to the situation.

In this type of fishing rod, the fitting portion differs depending on the "extended state" and "storing state" in the far table, but is one place (proximal end end outer peripheral surface) in the far table. For this reason, repeated use over a prolonged period of time causes remarkable wear of the proximal end of the proximal end, which causes the fracture of the peripheral edge of the proximal end. Also causes a decrease in the fitting force.

It is an object of the present invention to provide a long fitting structure capable of sufficiently maintaining a fitting force over a long period of time with a simple structure.

The fitting structure by the 1st aspect of this invention WHEREIN: The large diameter pole which has a cylindrical fitting member in a base end side in the fitting structure of the cylindrical pole connected by the pull-out form, and repair of a large diameter pole It comprises a small diameter pole connected to the side in the form of a pull, and having a small diameter fitting portion whose outer peripheral surface is small hardened in a predetermined range in the axial direction from the proximal end and which can be fitted into the fitting member.

According to this structure, in the extended state in which the small diameter pole is drawn out to the repair side of the large diameter pole, the proximal end outer circumferential surface of the small diameter pole is fitted and fixed to the inner peripheral surface of the large diameter pole in the same manner as a normal fishing rod. At this time, the small diameter fitting part of the base end side edge part of a small diameter pole does not participate in the fitting of a small diameter pole and a large diameter pole with respect to an outer diameter. In addition, the peripheral edge of the base end side edge of a small diameter pole does not directly contact the inner periphery of the repair side edge of a large diameter pole.

On the other hand, in the storage state in which the small-diameter pole is inserted into the large-diameter pole, the small-diameter fitting portion of the outer circumference of the proximal end of the small-diameter pole is inserted into the fitting member and fitted. At this time, parts other than the small diameter fitting part of the base end side edge of a small diameter pole are not inserted in a fitting member, and do not participate in the fitting of a small diameter pole and a large diameter pole.

After manufacturing a pole, such a small diameter fitting part can shave a part of outer peripheral surface of a base end side, and can process it easily, and also manufacture is easy.

The fitting structure by the 2nd aspect of this invention WHEREIN: The large diameter pole which has a cylindrical fitting member in a base end side in the fitting structure of the cylindrical pole connected by the pull-out form, and the pull type to the repair side of a large diameter pole. A small diameter pole having a reverse tapered portion or a straight tapered portion which does not change in outer diameter, which is tapered so that its outer circumferential surface becomes smaller in the axial direction from the proximal end to the proximal side toward the proximal side, and which can be fitted in the fitting member. It is provided.

Also in this structure, the same operation as in the first embodiment of the present invention described above is recognized. In other words, in the extended state in which the small diameter pole is extended to the repair side of the large diameter pole, the reverse taper portion or the straight tapered portion at the proximal end of the small diameter pole does not participate in fitting the small diameter pole and the large diameter pole in relation to the outer diameter. In addition, the base end side peripheral edge of a small diameter pole does not directly contact the inner periphery of the repair side edge of a large diameter pole. On the other hand, in the storage state in which the small-diameter pole is inserted into the large-diameter pole, only the reverse taper portion or the straight tapered portion of the base end side outer periphery of the small-diameter pole is inserted into and fitted to the fitting member. And after manufacturing a pole, such an inverted taper part can be easily processed by shaving a part of outer peripheral surface of a base end side, and manufacture is easy.

The fitting structure which concerns on the 3rd aspect of this invention is a structure of the 1st or 2nd aspect of the said invention WHEREIN: The fitting member of a large diameter pole is formed as a part integrally with a large diameter pole.

In this structure, the fitting member is formed as a part of the large diameter pole so that the fitting member does not unnecessarily separate from the large diameter pole.

EMBODIMENT OF THE INVENTION Hereinafter, 1st Embodiment of this invention is described, referring drawings.

As shown in FIG. 1, the middle barrel fishing rod according to the first embodiment of the present invention includes a far end 1, a far end 2 connected to the waterline side of the far end 1, and It has the 1st squadron 3 (middle | middle) connected to the repair side of the original bed 2, the 2nd squadron 4, and the chocolate bar 5 connected to the repair side of the 2nd squadron 4. As shown in FIG. These circular belts 1 to 5 are formed of prepregs impregnated with synthetic resins such as carbon fibers or glass fibers, and are tubular members tapering toward the end (see FIG. 2 and the like). Further, the original bed 2 to the chocolate bar 5 are sequentially inserted into the pole on the proximal side from the waterline side, and are accessible, and are connected in a so-called pull type. Moreover, the number of poles is suitably set by the length of the whole fishing rod etc. which are needed, It is not limited to five in this way, It can use in arbitrary numbers.

The far end 1 has a reel seat 8 which is formed on the outer circumferential surface and can be detachably attached to the reel 7, and a stopper 10 is attached to the proximal end. Moreover, the fishing rod inlet 9 which is formed in the outer periphery of the repair side and introduces the fishing line L which came out of the reel 7 in the pole inside is formed in the original table 2, and it arrange | positions so that the fishing line inlet 9 may be covered. Fishing line guide G is fixed. A top guide 6 is attached to the repair side end of the chord holder 5, and the fishing line L from the reel 7 is guided to the fishing line passage 100 through the fishing line guide G and the fishing line inlet 9, It is guided out from the top guide 6 on the side.

As shown in Fig. 2, the far end 1 is a regular tapered taper to be slightly tapered toward the end, but a short cylindrical fitting member 20 is inserted and fixed inside the proximal end. have. A thread is formed in the inner peripheral surface of the base end side of this fitting member 20, and the stopper 10 is attached to this so that attachment or detachment is possible. A chamfer or the like may be provided at the repair side end of the fitting member 20. In addition, as the fitting member 20, as shown in FIG. 5, you may provide the groove | channel 20a of the longitudinal direction at intervals in the circumferential direction on the inner peripheral surface. By forming a plurality of such grooves 20a, it is possible to prevent the original object 2 from sticking when fitting with the original object 2 described later.

On the other hand, although the original counterpart 2 is also a tapered body which becomes taper toward the end, the outer peripheral surface of the proximal end is slightly larger in diameter than the other part in a predetermined range (a range of about 70 to 80 mm from the proximal end). The fitting surface 2a is formed. Further, the small-diameter small diameter fitting portion 30 is formed in a predetermined range (approximately, about 10 to 15 mm) in the axial direction from the proximal end of the fitting surface 2a. The outer diameter of this fitting surface 2a is larger than the inner diameter of the fitting member 20, and the outer diameter of the small diameter fitting part 30 is set so that it may substantially correspond to the inner diameter of the fitting member 20. As shown in FIG. This design manufactures the original base 2 by making only the base end side only a little larger in diameter, and grind | polishing and shaving the base end side outer peripheral surface.

In a fishing rod having such a structure, when fishing, the rods are sequentially drawn out to the waterline side, and the rods are fitted to each other in a pull-out form to be used as a fishing rod. In addition, at the time of storing, the fitting of each pole is released, and the pole of the repair side is accommodated in the pole of the base end side in order to make it compact. In the far table 1 and the far table 2, the far table 2 can be fitted together not only in the state (extended state) withdrawn from the far table 1, but also in a state of storing (storing state), It is also possible to fish while adjusting the length of the entire fishing rod.

In other words, in the extended state in which the original table 2 is drawn out to the waterline side of the original table 1, the fitting surface 2a of the base end side circumferential surface of the original table 2 is similar to the original table 1 in the same manner as in the usual fishing rod. ) To the inner circumferential surface of the repair side. At this time, the small-diameter fitting part 30 of the base end side of the original base 2 does not participate in fitting. In addition, the peripheral edge of the base end side of the original base 2 also does not contact the inner periphery of the repair side end of the original base 1. On the other hand, as shown in FIG. 3, in the storage state in which the original table 2 is inserted into the original table 1, the small diameter fitting portion 30 at the proximal end of the original table 2 is fitted to the fitting member 20. Insert into and fit inside. At this time, a portion other than the small diameter fitting portion 30 at the proximal end of the far table 2 is not inserted into the fitting member 20 and is not involved in the fitting of the far table 2 and the far table 1. Do not.

[Second embodiment]

EMBODIMENT OF THE INVENTION Hereinafter, 2nd Embodiment of this invention is described, referring drawings.

As shown in FIG. 4, the original counterpart 52 of the fishing rod which concerns on 2nd Embodiment of this invention is also a tapered body tapering so that it may become thinner to the end, and a base end side outer peripheral surface is constant similarly to 1st Embodiment. The diameter is slightly larger than the other portions in the range (a range of about 70 to 80 mm from the proximal end side), and the fitting surface 52a is formed.

On the other hand, in the tapered end portion of the fitting surface 52a, in detail, the taper is reversely tapered so as to be small-cured toward the proximal side in a predetermined range (for example, in the range of about 10 to 30 mm) in the axial direction from the proximal end. It becomes the reverse taper part 60. The outer diameter of this fitting surface 52a is larger than the inner diameter of the fitting member 20, and the outer diameter of the inverse taper part 60 is set so that it may be inserted in the fitting member 20. As shown in FIG. Such a design is produced by slightly hardening only the base end 52 at the base end side, and then grinding and shaving the base end side outer circumferential surface. And when employ | adopting such a fitting structure, it is preferable to also make the magnetic side part fitting to the reverse taper part 60 into the tapered inner diameter according to this reverse taper.

The middle barrel fishing rod which has such a structure also exhibits the same effect as 1st Embodiment. That is, in the extended state which pulled out the original base 52 to the waterline side of the original base 1, the fitting surface 52a of the base end side outer peripheral surface of the original base 52 is similar to the original base 1 like a fishing rod of a normal drawing type. ) Is fixed to the inner peripheral surface of the repair side (see FIG. 4). At this time, the reverse taper part 60 of the base end side of the original base 52 does not participate in fitting. In addition, the base end side peripheral edge of the base 52 does not contact the inner periphery of the repair side end of the base 1. On the other hand, in the storage state in which the original base 52 is inserted into the original base 1, the reverse taper portion 60 at the proximal end of the original base 52 is inserted into the fitting member 20 and fitted. At this time, portions other than the inverse taper portion 60 at the proximal end of the base 52 are not inserted into the fitting member 20 and are not involved in the fitting of the base 2 and the base 1. Do not.
