Description

本発明は、実釣時において、長さ調節が可能な釣竿に関する。   The present invention relates to a fishing rod that can be adjusted in length during actual fishing.

従来、魚釣りに用いられる釣竿の一つとして、複数の竿杆を備え、長さ調節が可能なものが知られている。このような長さ調節が可能な釣竿は、大径の竿杆（元竿）に対して、それよりも穂先側にある小径の竿杆（元上竿）を収納し、その収納状態が固定できるような構造となっている。例えば、特許文献１には、元竿の先端側内周面に第１挟圧部を形成すると共に、基端側内周面に第２挟圧部を形成し、この元竿に収納される元上竿の先端側の外周面に、周方向に沿って摩擦条面を形成した長さ調節可能な釣竿が開示されている。   2. Description of the Related Art Conventionally, as one of fishing rods used for fishing, one having a plurality of rods and capable of adjusting the length is known. A fishing rod with adjustable length accommodates a small diameter rod (former rod) on the tip side of a large diameter rod (former rod), and the storage state is fixed. It has a structure that can be done. For example, in Patent Document 1, a first pinching portion is formed on the inner peripheral surface of the front end side of the main shaft, and a second pressing portion is formed on the inner peripheral surface of the base end side, and is stored in the main rod. A fishing rod that can be adjusted in length has been disclosed in which a friction surface is formed along the circumferential direction on the outer peripheral surface on the tip side of the original upper rod.

このような構成では、実釣時において、全体の長さを短くしたい場合、前記元上竿を元竿に収納すると、前記第１挟圧部と第２挟圧部によって、元上竿が元竿内で収納、固定された状態となり、釣竿全体の長さを短くすることができる。また、元上竿に形成された摩擦条面は、周方向に沿って所定間隔で凸部を形成した構造となっており、これが摩擦条面で構成される第１挟圧部との間で摩擦力を生じさせることから、元上竿の回転を阻止して元竿と元上竿との間で相対姿勢の安定化が図れるようになっている。
実開平３−１０８３６５号 In such a configuration, when it is desired to shorten the overall length during actual fishing, when the former upper rod is housed in the former rod, the original upper rod is caused to be the original by the first clamping portion and the second clamping portion. It is in a state of being housed and fixed in the rod, and the entire length of the fishing rod can be shortened. Moreover, the friction surface formed in the upper collar has a structure in which convex portions are formed at predetermined intervals along the circumferential direction, and this is between the first pinching portion constituted by the friction surface. Since the frictional force is generated, the rotation of the upper arm is prevented, and the relative posture can be stabilized between the upper arm and the upper arm.
Japanese Utility Model Publication No. 3-108365

上記したような長さ調節が可能な釣竿は、元上竿の先端側外周面に形成された摩擦条面と、元竿の先端側内周面に形成された第１挟圧部（摩擦条面）との関係で、長さ調節を繰り返すと両者の摩擦により継合力が低下するという問題がある。すなわち、伸長・収縮動作を頻繁に繰り返すと、元竿先端側の内周面に形成された第１挟圧部が次第に磨耗してしまい、この結果、収縮時や伸長時において、元竿と元上竿との間の継合力が弱くなって、実釣時に元上竿が元竿に対して回転したり、或いは軸方向にずれる、といった問題が生じる。   The fishing rod capable of adjusting the length as described above includes a friction strip formed on the outer peripheral surface of the front end of the upper rod and a first clamping portion (friction strip) formed on the inner peripheral surface of the front end of the main rod. There is a problem that when the length adjustment is repeated, the joint force decreases due to friction between the two. That is, if the stretching / shrinking operation is frequently repeated, the first pinching portion formed on the inner peripheral surface on the front end side of the marsket gradually wears out. The joint force between the upper rod becomes weak, and there arises a problem that the upper rod rotates relative to the main rod during actual fishing or shifts in the axial direction.

本発明は、上記した問題に基づいてなされたものであり、長さ調節が可能な釣竿において、元上竿と元竿との間で伸長・収縮を繰り返しても、両者の間で安定した継合力が得られる釣竿を提供することを目的とする。   The present invention has been made on the basis of the above-described problem, and in a fishing rod capable of adjusting its length, even if the extension and contraction are repeated between the former upper rod and the former rod, the stable connection between the two is possible. An object of the present invention is to provide a fishing rod that can obtain a resultant force.

上記した目的を達成するために、本発明に係る釣竿は、元竿と、前記元竿に対して振り出し式に収納される元上竿とを有する構成において、前記元上竿の外面には、長さ調節用の継合領域が形成されており、前記元竿の先端内面には、前記元上竿を元竿に収納した際、前記継合領域と継合して元上竿の回転を抑制する回転抑制部材が設置されており、前記元上竿を元竿に対して伸長した際、前記元上竿と元竿は、前記回転抑制部材よりも基端側で継合されることを特徴としている。   In order to achieve the above-described object, the fishing rod according to the present invention has a main rod and an upper rod that is housed in a swinging manner with respect to the former rod. A joining region for adjusting the length is formed, and when the upper arm is stored in the former, the inner surface of the tip of the former is joined with the joining region to rotate the upper arm. The rotation suppression member which suppresses is installed, and when the former upper arm is extended with respect to the main arm, the upper arm and the main arm are joined on the base end side with respect to the rotation suppression member. It is a feature.

上記した構成の釣竿では、元上竿を元竿に対して収縮・伸長することで、全体として長さ調節が可能となる。元上竿を元竿に収納すると、元上竿の外面に形成された継合領域が、元竿の先端内面に形成された回転抑制部材と継合して、回転が抑制された状態で固定され、全体の寸法が短くなる。また、収納された元上竿を元竿から伸長すると、元上竿と元竿は、前記回転抑制部材よりも基端側で継合されることから、伸長時において、前記回転抑制部材に対する摩擦力が軽減されるようになり、回転抑制部材が磨耗等することはない。従って、元上竿と元竿との間で伸長・収縮を繰り返しても、回転抑制部材部分の継合力の低下が抑制され、両者の間で安定した継合力が得られるようになる。   In the fishing rod having the above-described configuration, the length can be adjusted as a whole by contracting and extending the upper rod relative to the former rod. When the former upper rod is stored in the former rod, the joining area formed on the outer surface of the former upper rod is joined with the rotation suppressing member formed on the inner surface of the leading end of the former rod, and the rotation is suppressed in a fixed state. And the overall dimensions are shortened. Further, when the stored upper arm is extended from the main arm, the upper arm and the main arm are joined together at the base end side with respect to the rotation suppressing member. The force is reduced and the rotation suppressing member is not worn. Therefore, even if the extension and contraction are repeated between the former upper collar and the former collar, the decrease in the joining force of the rotation suppressing member portion is suppressed, and a stable joining force can be obtained between them.

本発明に係る釣竿によれば、元上竿と元竿との間で長さ調節をすべく伸長・収縮を繰り返しても、両者の間で安定した継合力が得られるようになる。   According to the fishing rod according to the present invention, a stable joining force can be obtained between the former rod and the former rod even when the extension and contraction are repeated to adjust the length.

Moreover, each rod which comprises the fishing rod R mentioned above is formed by the well-known method which makes the prepreg sheet | seat which impregnated the reinforced fiber the synthetic resin into a tube, for example.

前記元竿１の外周には、その先端側にリールが装着されるリールシート５と、その後端側に位置するグリップ６が順次取着されており、元竿１を構成する竿管は外部に露出しない状態となっている。また、元竿１の基端部には、尻栓７が着脱自在に装着されている。   A reel seat 5 on which a reel is mounted on the front end side thereof and a grip 6 located on the rear end side thereof are sequentially attached to the outer periphery of the main bar 1, and the bar tube constituting the main bar 1 is externally attached. It is not exposed. In addition, a bottom plug 7 is detachably attached to the base end portion of the main shaft 1.

前記リールシート５は、ポリアミドやＡＢＳ樹脂などの合成樹脂によって筒状に形成されており、元竿１の外周面に取着されている。リールシート５には、リール脚を載置するリール脚載置部５ａ、リール脚を固定するための固定フード５ｂが形成されており、リール脚載置部５ａに載置されたリールは、固定フード５ｂと移動ナットとして構成される移動フード５ｃとの間で固定されるようになっている。なお、リールシート５の前方側の外周面には、移動フード５ｃが螺合されるように、雄ネジ部が形成されている。また、リールシート５のリール脚載置部５ａと反対側には、実釣時において指を掛けるようにトリガー５ｄが形成されている。   The reel sheet 5 is formed in a cylindrical shape from a synthetic resin such as polyamide or ABS resin, and is attached to the outer peripheral surface of the main shaft 1. The reel sheet 5 is formed with a reel leg placing portion 5a for placing the reel legs, and a fixing hood 5b for fixing the reel legs. The reel placed on the reel leg placing portion 5a is fixed. It is fixed between the hood 5b and a moving hood 5c configured as a moving nut. A male thread portion is formed on the front outer peripheral surface of the reel seat 5 so that the movable hood 5c is screwed together. Further, a trigger 5d is formed on the opposite side of the reel seat 5 from the reel leg mounting portion 5a so that a finger can be hooked during actual fishing.

前記グリップ６は、握り心地が良好となるように、軟質な部材、例えばＥＶＡやウレタンなどの発泡材、合成ゴム、天然ゴムなどによって形成されている。   The grip 6 is formed of a soft member, for example, a foamed material such as EVA or urethane, synthetic rubber, natural rubber, or the like so that the grip comfort is good.

前記元竿１の後端外周には、グリップ６との間に硬質樹脂（例えば、ポリアミドやＡＢＳ樹脂等）によって形成された筒状体７ａが止着されており、元竿から突出する部分に雌ネジ部７ｂが形成されている。この雄ネジ部７ｂには、緩み止め用のＯリング７ｃを介在させて前記尻栓７が螺合されている。なお、尻栓７は、合成樹脂や金属によって形成されている。   A cylindrical body 7a formed of a hard resin (for example, polyamide, ABS resin, etc.) is fixed to the outer periphery of the rear end of the main bar 1 between the grip 6 and a portion protruding from the main bar. A female screw portion 7b is formed. The butt plug 7 is screwed into the male screw portion 7b with an O-ring 7c for preventing loosening interposed. Note that the bottom plug 7 is made of synthetic resin or metal.

前記元竿１の基端側には、元上竿２が収納された際、元上竿の基端領域を係止する係止部材８を設けておくことが好ましい。この係止部材８は、例えば、収納された元上竿２の基端側外周面を圧着するように、リング状部材で構成することが可能であり、ポリアミド、ＡＢＳ樹脂、ポリウレタン等の合成樹脂によって形成される。係止部材８の内面には、基端側に向けて次第に縮径するテーパ面８ａが形成されており、収納される元上竿２の基端側をスムースに案内して、基端側の外周面を圧着するように構成されている。このような係止部材８は、雄ネジ部８ｂを形成しておき、前記筒状体７ａに螺合するように尻栓７に一体的に設けておくことが可能である。   It is preferable that a locking member 8 is provided on the base end side of the base rod 1 to lock the base end region of the base rod when the base rod 2 is stored. The locking member 8 can be formed of a ring-shaped member so as to crimp the base end side outer peripheral surface of the housed upper collar 2, for example, and is made of synthetic resin such as polyamide, ABS resin, or polyurethane. Formed by. On the inner surface of the locking member 8, a tapered surface 8 a that gradually decreases in diameter toward the base end side is formed, and the base end side of the original upper collar 2 that is accommodated is smoothly guided to It is comprised so that an outer peripheral surface may be crimped | bonded. Such a locking member 8 can be provided integrally with the end plug 7 so as to form a male threaded portion 8b and to be screwed into the cylindrical body 7a.

なお、係止部材８については、元上竿２を係止できる構成であれば良く、元上竿の基端側の内面と係合するような構成であっても良い。このような係止部材は、基端側に移行するに連れて次第に拡径する円筒状（円柱状）の部材によって形成することが可能である。   In addition, about the latching member 8, what is necessary is just the structure which can latch the upper collar 2 and the structure which engages with the inner surface of the base end side of an upper collar may be sufficient. Such a locking member can be formed of a cylindrical (columnar) member that gradually increases in diameter as it moves to the proximal end side.

前記元竿１の先端内面には、元上竿２を元竿１に収納した際、元上竿２の外面に形成された継合領域２ａと継合して元上竿２の回転を抑制する回転抑制部材１０が設置されている。   On the inner surface of the front end of the main bar 1, when the upper bar 2 is stored in the main bar 1, the rotation of the upper bar 2 is suppressed by joining with the joining region 2 a formed on the outer surface of the upper bar 2. A rotation suppressing member 10 is installed.

ここで、図４から図６を併せて参照しながら、継合領域２ａ及び回転抑制部材１０について説明する。なお、これらの図において、図４は、図３（ｂ）のＡ−Ａ線に沿った断面図、図５（ａ）は、継合領域を拡大して示す図、図５（ｂ）は、Ｂ−Ｂ線に沿った断面図、そして、図６（ａ）は、回転抑制部材の正面図、図６（ｂ）は、部分縦断面図である。   Here, the joining area | region 2a and the rotation suppression member 10 are demonstrated, referring also FIGS. 4-6. In these figures, FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3B, FIG. 5A is an enlarged view of the joining region, and FIG. FIG. 6A is a front view of the rotation restraining member, and FIG. 6B is a partial vertical cross-sectional view.

回転抑制部材１０は、元竿１とは別体でリング状に形成されており、円筒部１０ａとフランジ部１０ｂとを備え、フランジ部１０ｂが元竿１の開口端面に当て付けられた状態で円筒部１０ａの外面が元竿１の先端内面に接着等によって取着される。回転抑制部材１０は、元上竿２が収納された際、継合領域２ａと継合して元上竿２が不用意に回転することを抑制する機能を備えており、例えば、ポリアミド、ＡＢＳ樹脂、ポリウレタン等の合成樹脂によって形成したり、合成ゴム、エラストマー等によって形成される。この場合、円筒部１０ａの内面には、継合する元上竿２との関係で摩擦力が高くなるように、回転抑制手段として、例えば、周方向に沿って凸部１０ｃが連続的に形成されている。   The rotation suppressing member 10 is formed in a ring shape separately from the main shaft 1, and includes a cylindrical portion 10 a and a flange portion 10 b, and the flange portion 10 b is in contact with the opening end surface of the main shaft 1. The outer surface of the cylindrical portion 10a is attached to the inner surface of the front end of the main shaft 1 by bonding or the like. The rotation restraining member 10 has a function to prevent the former collar 2 from being rotated inadvertently when joined to the joining region 2a when the former collar 2 is stored. For example, polyamide, ABS It is formed of a synthetic resin such as a resin or polyurethane, or is formed of a synthetic rubber or an elastomer. In this case, for example, a convex portion 10c is continuously formed along the circumferential direction on the inner surface of the cylindrical portion 10a as a rotation suppressing means so that the frictional force is increased in relation to the former upper collar 2 to be joined. Has been.

なお、回転抑制手段は、凸部１０ｃ以外にも、円筒部１０ａの内面を粗面化したり、エンボス加工すること等で形成しても良い。また、元上竿２の継合領域２ａと接触する部分は、継合領域２ａと比較して柔らかい状態になっていることが好ましい。すなわち、回転抑制部材１０は、元上竿２の継合領域２ａと比較して、柔らかい素材で形成しておくことが好ましい。   The rotation suppressing means may be formed by roughening the inner surface of the cylindrical portion 10a or embossing other than the convex portion 10c. Moreover, it is preferable that the part which contacts the joining area | region 2a of the former upper collar 2 is a soft state compared with the joining area | region 2a. That is, it is preferable that the rotation suppression member 10 is formed of a soft material as compared with the joining region 2a of the former upper collar 2.

前記元上竿２の外面に形成される継合領域２ａは、元上竿２を元竿１に収納した際に、回転抑制部材１０と継合する部分に膨出状に形成されている。このため、継合領域２ａは、例えば、元上竿２を、繊維強化樹脂（プリプレグシート）によって管状に成形する際、所定の領域に補強シートを配置する等して、該当部分を肉厚状にすることで一体形成することが可能である。本実施形態では、肉厚状に形成した継合領域２ａに、周方向に所定間隔おいて軸長方向に延出する凹溝２ｃを形成しており、これにより、元上竿２を元竿１に収納した際に、図４に示すように、継合領域２ａの凹溝２ｃと前記回転抑制部材１０の内面に形成された凸部１０ｃが継合し、元上竿２は、元竿１に対して周方向に回転することが抑制される。   The joint region 2 a formed on the outer surface of the former upper collar 2 is formed in a bulging shape at a portion where the former upper collar 2 is joined to the rotation suppressing member 10 when the former upper collar 2 is stored in the former collar 1. For this reason, the joining area | region 2a, for example, arrange | positions a reinforcement sheet | seat in a predetermined | prescribed area | region, etc., when shape | molding the former upper collar 2 into a tube shape with fiber reinforced resin (prepreg sheet | seat), etc. It is possible to form integrally. In the present embodiment, the groove 2c extending in the axial length direction at a predetermined interval in the circumferential direction is formed in the joining region 2a formed in a thick shape. 4, the concave groove 2c of the joining region 2a and the convex portion 10c formed on the inner surface of the rotation suppressing member 10 are joined together as shown in FIG. 1 is prevented from rotating in the circumferential direction.

そして、前記元上竿２を元竿１に対して伸長した際、元上竿２と元竿１は、図２に示すように、回転抑制部材１０が存在する領域よりも基端側で継合されるように構成されている。具体的には、元竿１の先端側内周の、回転抑制部材１０が取着される領域よりも基端側に、先端に移行するに連れて次第に縮径する第１テーパ１Ａが形成されており、元上竿２の基端側外周に、先端に移行するに連れて次第に縮径する第２テーパ２Ａが形成されており、元上竿２を元竿１に対して伸長した際に、両テーパ１Ａ，２Ａが継合して元上竿２が抜けないように構成されている（両テーパによる継合領域をＬで示す）。   Then, when the upper arm 2 is extended with respect to the main shaft 1, the upper arm 2 and the main shaft 1 are joined on the proximal side with respect to the region where the rotation suppressing member 10 exists, as shown in FIG. It is comprised so that it may be united. Specifically, a first taper 1A that gradually decreases in diameter as it moves to the distal end is formed on the proximal end side of the inner periphery on the distal end side of the base rod 1 from the region where the rotation suppressing member 10 is attached. A second taper 2A that gradually decreases in diameter as it moves to the distal end is formed on the outer periphery on the base end side of the upper collar 2, and when the upper collar 2 is extended with respect to the original collar 1 The two tapers 1A and 2A are joined so that the upper collar 2 does not come out (the joining region by both tapers is indicated by L).

この場合、元上竿２が元竿１に対して伸長して両テーパ１Ａ，２Ａが継合して固定状態となった際、図２（ｂ）に示すように、回転抑制部材１０と元上竿２の外周面とは、接触することなく隙間Ｇが生じるように形成されることが好ましい。すなわち、上記した両テーパ１Ａ，２Ａは、元上竿２を元竿１に対して伸長した際、元上竿２の外周面は、回転抑制部材１０の内面と非接触状態が維持されるように設定されていることが好ましい。このため、図２（ｂ）に示すように、元上竿２の基端領域は、略ストレート状に形成されると共に、テーパ２Ａが形成される領域を膨出させており、テーパ２Ａが形成される領域よりも前方側の領域Ｌ２を非接触状態としている。   In this case, when the upper arm 2 is extended with respect to the main shaft 1 and the both tapers 1A and 2A are joined and fixed, as shown in FIG. It is preferable that the outer circumferential surface of the upper collar 2 is formed so that the gap G is generated without contact. That is, when both the above-described tapers 1A and 2A extend the upper collar 2 with respect to the former collar 1, the outer peripheral surface of the upper collar 2 is maintained in a non-contact state with the inner surface of the rotation suppressing member 10. It is preferable that it is set to. For this reason, as shown in FIG. 2 (b), the base end region of the upper collar 2 is formed in a substantially straight shape, and the region where the taper 2A is formed bulges, and the taper 2A is formed. The region L2 on the front side of the region to be applied is in a non-contact state.

以上のように構成された釣竿によれば、元上竿２と元竿１との間で長さ調節を繰り返しても、伸長時には、回転抑制部材１０は、元上竿２との間で大きな摩擦力が作用しないため、磨耗することがなくなる。この結果、収縮時や伸長時において、元竿１と元上竿２との間の継合力が弱くなることはなく、実釣時に元上竿２が元竿１に対して回転したり、軸方向にずれる、といった問題が生じることはない。特に、本実施形態では、伸長時には、回転抑制部材１０は、元上竿２と非接触状態が維持されるため、その磨耗を確実に抑制することが可能となる。   According to the fishing rod configured as described above, even when the length adjustment is repeated between the former upper rod 2 and the former rod 1, the rotation suppressing member 10 is large between the former upper rod 2 when extended. Since frictional force does not act, it will not wear out. As a result, the joint force between the main rod 1 and the upper rod 2 does not weaken during contraction or extension, and the upper rod 2 rotates relative to the main rod 1 during actual fishing, There will never be a problem of shifting in the direction. In particular, in this embodiment, at the time of extension, the rotation suppressing member 10 is kept in a non-contact state with the upper collar 2, so that it is possible to reliably suppress wear.

この場合、回転抑制部材１０の内面と、元上竿２の外面との間の隙間Ｇについては、大きくし過ぎると、隙間に異物が入り込み易くなるため、１ｍｍ以下となるように設定することが好ましい。また、回転抑制部材１０の軸方向長さＬ１については、短すぎると収納時において十分な継合力が得られず、長すぎると、伸長時において撓み性を阻害することから５〜１５ｍｍ程度に設定しておくことが好ましい。さらには、非接触領域Ｌ２が長くなり過ぎると、伸長時において、撓み性を阻害したり元上竿表面への応力集中が生じるため、回転抑制部材１０の軸方向の長さＬ１との比率（Ｌ１／Ｌ２）については、６０〜１００％程度に設定しておくことが好ましい。   In this case, if the gap G between the inner surface of the rotation suppressing member 10 and the outer surface of the former upper collar 2 is excessively large, foreign matter easily enters the gap, so that it can be set to 1 mm or less. preferable. Moreover, about the axial direction length L1 of the rotation suppression member 10, when it is too short, sufficient joining force is not acquired at the time of accommodation, and when too long, since flexibility will be inhibited at the time of expansion | extension, it sets to about 5-15 mm. It is preferable to keep it. Furthermore, if the non-contact region L2 becomes too long, the flexibility is hindered or the stress concentration on the surface of the upper collar occurs at the time of extension, so the ratio with the axial length L1 of the rotation suppressing member 10 ( L1 / L2) is preferably set to about 60 to 100%.

また、上記した構成の釣竿では、元竿１の基端側に、元上竿２が収納された際、元上竿２を係止する係止部材８が設けられているため、収納時における元上竿２のガタ付きや、元上竿２の不用意な突出を確実に防止することができ、これにより、回転抑制部材の磨耗を確実に抑制することが可能となる。   Further, in the fishing rod having the above-described configuration, when the upper rod 2 is stored on the base end side of the main rod 1, the locking member 8 that locks the upper rod 2 is provided. It is possible to reliably prevent backlash of the upper upper collar 2 and inadvertent protrusion of the upper upper collar 2, thereby reliably suppressing wear of the rotation suppressing member.

以上、本発明の実施形態について説明したが、本発明は、上記した実施形態の形状に限定されることはなく、種々変形することが可能である。   As mentioned above, although embodiment of this invention was described, this invention is not limited to the shape of above-described embodiment, It can change variously.

本発明に係る釣竿は、上記した中通し式以外にも、外ガイド式であっても良いし、渓流竿のようにリールを装着しない釣竿に適用しても良い。また、その竿節数についても適宜変更することが可能であり、長さ調節が成される部分となる元竿と元上竿との関係は、釣竿の中間節部分であっても良い。   The fishing rod according to the present invention may be an outer guide type other than the above-described centering type, or may be applied to a fishing rod that is not mounted with a reel, such as a mountain stream rod. Further, the number of rods can be changed as appropriate, and the relationship between the main rod and the upper rod which is a portion where the length is adjusted may be an intermediate node portion of the fishing rod.

また、上記した回転抑制部材１０については、元竿１に一体形成したものであっても良いし、元上竿２に形成される継合領域２ａについては、管状体を成形した後に、別体として膨出部を取着する構成であっても良い。さらに、継合領域２ａが形成される位置や、その具体的な構成についても適宜変形することが可能である。   Moreover, about the above-mentioned rotation suppression member 10, what was integrally formed in the main rod 1 may be formed, and about the joining area | region 2a formed in the former upper rod 2, after forming a tubular body, it separates The structure which attaches a bulging part as may be sufficient. Furthermore, the position where the joining region 2a is formed and the specific configuration thereof can be modified as appropriate.
