Description

The present invention relates to a fishing line guide fixing structure that is fixed to a fishing rod and guides a fishing line, and a fishing rod having such a fixing structure.

In general, a fishing line guide that is attached and fixed to a fishing rod does not have sufficient strength against a tensile force in the rod tip direction, and may come off the fishing rod when a load exceeding a certain level is applied. For this reason, various fishing line guide fixing structures have been proposed in the past, which make it difficult for the fishing line guide to come off and have sufficient strength to withstand the load.

For example, as a method for increasing the pull-out strength of the fishing line guide, modification of the winding method of the fixing line for fixing the fishing line guide, modification of the adhesive infiltrated into the wound fixing line, or and a rod of a fishing rod.

In particular, in relation to the modification of the fixed line winding method, in Patent Document 1, a bobbin thread layer is formed for stably placing the leg portion of the fishing line guide on the rod of the fishing rod, and on this bobbin thread layer After placing the leg, a needle thread layer for fixing the leg is formed over the leg and the bobbin thread layer.

On the other hand, Patent Documents 2 and 3 disclose fixing structures in which a fishing line guide is fixed to a fishing rod only by an upper thread layer without providing a bobbin thread layer. In this case, Patent Document 2 employs a fixing form in which gaps are formed between adjacent filaments and synthetic resin is introduced into the gaps. Further, Patent Document 3 employs a fixing form in which gaps are formed in the thread material and the gaps are filled with an adhesive.

According to the fishing line guide fixing structure disclosed in the above-mentioned Patent Document 1, by forming the lower thread layer, the leg portion of the fishing line guide can be stably placed, and the pull-out strength of the fishing line guide can be increased. However, in Patent Document 1, since the bobbin thread layer has a small diameter and is tightly wound, synthetic resin (adhesive) is less likely to enter between the threads of the bobbin thread layer and between the bobbin thread layer and the rod rod ( Insufficient penetration (filling) of the adhesive between the fishing line guide and the rod). In addition, since the bobbin thread layer extends longer than the leg portion of the fishing line guide and the outer diameter of the thread of the upper thread layer is larger than the outer diameter of the thread of the bobbin thread layer, there is a risk that the appearance will be impaired. , the range of use of the upper thread layer may be limited. Furthermore, since different threads are used for the lower thread layer and the upper thread layer, it is necessary to replace the threads, which increases the number of processes.

On the other hand, the fishing line guide fixing structures disclosed in Patent Documents 2 and 3 do not have a bobbin thread layer, so the strength of the fishing line guide to come off is insufficient. It is also difficult for the adhesive to enter between the In particular, in Patent Document 2, since the synthetic resin that has entered the gap between the filament bodies is exposed in a circular shape, the side opposite to the fishing line guide mounting portion is particularly susceptible to direct impact from the outside and is easily damaged. Further, in Patent Document 3, since the adhesive is filled separately from the application of the thread tacking material, the work is complicated, and there is a possibility that the adhesive cannot be filled due to the presence of the thread tacking material.

The present invention has been made based on the above-described problems, and is capable of filling and/or filling an adhesive (synthetic resin) between a fishing line guide and a rod without complicating the fixing work and without impairing the appearance. Another object of the present invention is to provide a fishing line guide fixing structure and a fishing rod that can increase the degree of infiltration and increase the fixing strength between the fishing line guide and the rod (having sufficient pull-out strength).

In order to solve the above-described problems, the present invention provides a fishing line having a ring holding portion that holds a guide ring through which a fishing line is inserted and a leg that extends from the ring holding portion and is fixed to the outer surface of a fishing rod. In the fixing structure of the guide, an upper thread winding layer formed by winding a fixing thread over the outer surface of the leg and the outer peripheral surface of the fishing rod, and a fixing thread passing between the leg and the fishing rod and a lower thread winding layer wound over the outer peripheral surface of the fishing rod, and the upper thread winding layer and the lower thread winding layer each have a fixing thread on the fixed side to which the leg is fixed. A gap is formed between the wound portions, and a tightly wound portion is formed in which the fixed line is densely wound on the non-fixed side opposite to the fixed side with respect to the longitudinal center axis of the fishing rod. It is characterized by

According to the above configuration, not only the upper thread winding layer for fixing the leg of the fishing line guide to the fishing rod but also the lower thread winding layer is provided between the leg of the fishing line guide and the fishing rod. and the fishing rod, and the existence of this gap shortens the time for the adhesive to reach each winding portion of the bobbin thread winding layer when the adhesive is subsequently applied on the fixed side. The adhesive will quickly soak into each turn. Moreover, since gaps are formed between the wound portions of the bobbin thread winding layer on the fixed side where the adhesive is applied, the gaps are filled with the adhesive (resin pools are formed). As a result, the degree of filling of the adhesive in the bobbin thread winding layer is increased, so that the bonding strength between the fishing line guide (leg) and the fishing rod is remarkably enhanced by the adhesive (resin layer). In addition, since gaps are formed between the wound portions of the fixed thread on the fixed side of the upper thread winding layer, the bonding strength is further increased by filling the gaps with the adhesive, thereby increasing the overall strength. As a result, the pull-out strength of the fishing line guide is remarkably improved.

Such high fixing strength is also supported by the guide removal strength test results shown in FIG. That is, the present inventor has proposed a fishing line guide fixing structure of the present invention having the above configuration, and a fishing line guide fixing structure without a lower thread winding layer and without a gap between the winding portions of the upper thread winding layer, A comparison test was conducted from the standpoint of pull-out strength, and the test results shown in FIG. 5 were obtained. In this test, the fixed line was wound around the fishing rod from 7 mm ahead of the tip of the leg of the fishing line guide, and fixed over the leg until it reached the base of the leg (transition region to the bent portion). A fishing line guide fixing structure (“comparative example”) with only an upper line wound layer without gaps (including two windings (two plies) of pillow winding that wraps around the front side of the bent portion), and a fishing line The first winding portion of the upper thread winding layer is formed by winding the fixed thread from the vicinity of the tip of the leg of the guide over the outer surface of the leg and the outer peripheral surface of the fishing rod for 10 turns (for 10 plies). After forming, the first winding portion of the bobbin thread winding layer is formed by winding the fixing thread by one ply over the outer peripheral surface of the fishing rod so as to pass between the leg portion and the fishing rod, and then, In order, the second winding portion of the upper thread winding layer for 5 plies, the second winding portion of the lower thread winding layer for 2 plies, the third winding portion of the upper thread winding layer for 5 plies, A fishing line guide fixing structure (the "present invention") formed by forming a third winding portion of a bobbin thread winding layer for 3 plies (including a pillow winding for 2 plies that wraps around the front side of the bent portion); A comparison was made regarding the load when the fishing line guide came off. Specifically, a tensile load was applied to the fishing line guide while holding the portion of the fishing rod with the fishing line guide fixing structure of the "comparative example" and "the present invention" in a vise, and the fishing line guide came out of the fishing rod. The load at the time point was recorded. FIG. 5 shows the recording result. As can be seen from this result, the average load value when the test was performed 10 times for each of the "comparative example" and the "present invention" was 10.8 kg for the "comparative example", while " The present invention was 16.5 kg. In other words, the "present invention" had about 1.5 times higher strength against removal than the "comparative example".

In addition, since the fishing line guide fixing structure of the present invention can obtain a high fixing strength (removal strength) in this way, it is not necessary to extend the lower line winding layer as long as in Patent Document 1 described above. There is no need to make the outer diameter of the fixing thread of the lower thread winding layer different from the outer diameter of the fixing thread of the upper thread winding layer. No ill effects.

Further, in the above configuration, the upper thread winding layer and the lower thread winding layer are formed by a common fixed thread, and on the fixed side, the winding portion of the lower thread winding layer and the upper thread winding are arranged along the axial direction of the fishing rod. It is preferable that the winding portions of the winding layers are alternately arranged. According to such a configuration, the gap between the winding portions of the upper thread winding layer and the lower thread winding layer is inevitably and efficiently formed. Since the lower thread winding layer is composed of the same single thread, it is not necessary to replace the thread as in the above-mentioned Patent Document 1, and the number of steps in the entire fixing work can be reduced (fixing work is easy and Become).

Further, in the above configuration, the bending portion is provided between the ring holding portion and the leg portion, and the number of windings of the fixing thread in the winding portion of the bobbin thread winding layer closest to the bending portion is the same as in the other winding portions. It is preferable that the number of windings is greater than the number of windings of the fixing thread. According to such a configuration, it is possible to increase the fixing strength at the winding portion of the lower thread winding layer closest to the bent portion, thereby preventing breakage at the portion of the upper thread winding layer near the bent portion. That is, the present inventors found in the above-mentioned test that the reason why the fishing line guide comes off in the fixing structure of the "comparative example" is that the wound portion (and the pillow winding portion) of the upper thread winding layer near the bent portion is broken. I found that Therefore, the number of windings of the fixing thread in the winding portion of the bobbin thread winding layer closest to the bent portion is made larger than the number of windings of the fixing thread in the winding portion other than the winding portion of the bobbin thread winding layer closest to the bending portion. By increasing the degree of infiltration of the adhesive into the wound portion, the fixing strength at this portion increases, and the load on the wound portion of the upper thread winding layer near the bent portion can be reduced (thus, can prevent breakage at the winding portion of the upper thread winding layer).

The present invention also provides a fishing rod having the structure for fixing the fishing line guide as described above.

According to the present invention, the degree of filling and/or infiltration of an adhesive (synthetic resin) between the fishing line guide and the rod is increased without complicating the fixing work and without impairing the appearance of the fishing line guide. It is possible to obtain a fishing line guide fixing structure and a fishing rod that can increase the fixing strength to the rod (having sufficient pull-out strength).

An embodiment of the present invention will be specifically described below with reference to the accompanying drawings.
As shown in FIG. 1, the fishing rod 1 of this embodiment includes a base rod 3, a middle rod 5, and a tip rod 10, and each rod is joined by a parallel splicing method. In addition, the fishing rod 1 is provided with a reel seat 4 on the base rod 3, and the base rod 3, the middle rod 5, and the tip rod 10 receive the fishing line unwound from the reel R attached to the reel seat 4.

In FIG. 1, the fishing line guide provided on the base rod 3 is indicated by 7A, the fishing line guide provided on the middle rod 5 is indicated by 7B, and the fishing line guide provided on the tip rod 10 is indicated by 7C. A top guide 8 is attached to the tip of the tip rod 10 . In this case, each of the fishing line guides 7A, 7B, 7C and the top guide 8 are attached to the outer peripheral surface of the rod by thread winding and adhesive, as will be described later.

Although the fishing rod 1 shown in FIG. 1 is configured as a parallel joint type, the joint structure of each rod may be a draw-out method, a reverse parallel connection method, or a spigot method. In addition, there may be a plurality of (two or more) middle poles 5, or there may be none. In addition, it may be composed of a single rod as a whole.

The base rod 3 and the middle rod 5 are preferably made of tubular bodies (hollow rods) made of fiber-reinforced resin. A fiber-reinforced resin prepreg (prepreg sheet) impregnated with a resin is wound around a metal core, subjected to a heating process, and then decored to form a tubular shape having a predetermined size according to a standard method.

FIGS. 2 and 3 show an enlarged view of a first embodiment of the fixing structure for fixing the fishing line guide 7 (7A, 7B, 7C) to the rods 5, 10 of the fishing rod 1. FIG. . As shown, the fishing line guide 7 includes a ring holding portion 15 that holds a guide ring 20 that guides the fishing line, and a leg portion 16 that extends from the ring holding portion 15 and is fixed to the outer surface of the fishing rod 1 . have. Further, the fishing line guide 7 has a bending portion 17 which rises upward between the ring holding portion 15 and the leg portion 16 to separate the ring holding portion 15 from the outer surface of the fishing rod 1 .

The fixing structure of this embodiment for fixing the fishing line guide 7 to the fishing rod 1 includes an upper thread winding layer 30 formed by winding the fixing line 18 over the outer surface of the leg portion 16 and the outer peripheral surface of the fishing rod 1. and a lower thread winding layer 40 formed by winding the fixed thread 18 over the outer peripheral surface of the fishing rod 1 so as to pass between the leg portion 16 and the fishing rod 1. - 特許庁In this case, in the needle thread winding layer 30, a gap c is formed between the winding portions 30A, 30B, 30C, and 30D of the fixing thread 18 on the fixed side S1 to which the leg portion 16 is fixed. Also, in the bobbin thread winding layer 40, a gap c is formed between the winding portions 40A, 40B, and 40C of the fixing thread 18 on the fixed side S1 to which the leg portion 16 is fixed. In addition, the upper thread winding layer 30 and the lower thread winding layer 40 formed in this manner cooperate with each other on the non-fixed side S2 opposite to the fixed side S1 with respect to the longitudinal central axis O of the fishing rod 1, A tightly wound portion 50 is formed in which the fixing thread 18 is tightly wound.

In particular, in the present embodiment, the upper thread winding layer 30 and the lower thread winding layer 40 are formed by a single fixed thread 18 in common. The wound portions 40A, 40B, 40C of the thread wound layer 40 and the wound portions 30A, 30B, 30C, 30D of the upper thread wound layer 30 are alternately arranged.

Specifically, the upper thread wound layer 30 and the lower thread wound layer 40 having such a configuration are formed by winding the fixing thread 18 as follows. Note that the number of turns of the fixing thread 18 in FIGS. 2 and 3 does not necessarily match the number of turns of the fixing thread 18 in the following description for the sake of simplification of illustration.

As shown in FIGS. 2 and 3, first, the fixing line 18 is passed from near the tip (left end in FIG. 2) of the leg 16 of the fishing line guide 7 over the outer surface of the leg 16 and the outer peripheral surface of the fishing rod. The first wound portion 30A of the upper thread wound layer 30 is formed by winding 10 rounds (10 plies) or more. Thereafter, the fixing thread 18 forming the first winding portion 30A is wound as it is over the outer peripheral surface of the fishing rod 1 so as to pass between the leg portion 16 and the fishing rod 1, thereby forming a lower thread winding layer. 40 first turns 40A are formed. Next, the fixing thread 18 is again wound by 5 plies over the outer surface of the leg 16 and the outer peripheral surface of the fishing rod 1 to form the second wound portion 30B of the upper thread wound layer 30. , the fixed thread 18 is wound as it is over the outer peripheral surface of the fishing rod 1 so as to pass between the leg 16 and the fishing rod 1, thereby forming the second wound portion 40B of the bobbin thread winding layer 40. to form

After that, the fixing thread 18 forming the second winding portion 40B of the lower thread winding layer 40 is wound over the outer surface of the leg portion 16 and the outer peripheral surface of the fishing rod 1 by five plies, thereby winding the upper thread. After forming the third winding portion 30C of the layer 30, the fixing thread 18 is wound as it is over the outer peripheral surface of the fishing rod 1 by three plies so as to pass between the leg portion 16 and the fishing rod 1. to form the third winding portion 40C of the bobbin thread winding layer 40 (therefore, the number of windings of the fixing thread 18 at this winding portion 40C closest to the bent portion 17 is The number of windings of the fixed thread 18 is greater than that of the fixed thread 18), and finally, the upper thread winding layer 30 is formed by winding the fixed thread 18 over the outer surface of the leg portion 16 and the outer peripheral surface of the fishing rod 1 to the root of the bent portion 17. Then, the fourth winding portion 30D is formed, and two plies of pillow winding are applied to the front side of the bent portion 17 to complete the winding. As a result, on the fixed side S1 where the leg portion 16 is fixed, the winding portions 40A, 40B, and 40C of the lower thread winding layer 40 and the winding portions 30A and 30B of the upper thread winding layer 30 are arranged along the axial direction of the fishing rod 1. , 30C, and 30D are alternately arranged with a gap c between them. Further, in such a winding configuration, the fixing thread 18 is densely wound without forming a gap on the non-fixing side S2 to form the densely wound portion 50 . Then, when such a wound form is obtained, an adhesive is applied onto the wound layers 30 and 40 .

As described above, according to the present embodiment, not only the needle thread winding layer 30 that fixes the leg portion 16 of the fishing line guide 7 to the fishing rod 1 but also the space between the leg portion 16 of the fishing line guide 7 and the fishing rod 1 is provided. Since the bobbin thread winding layer 40 is also provided in the bottom thread winding layer 40, a gap c is generated between the leg portion 16 and the fishing rod 1. Due to the presence of this gap c, when the adhesive is applied on the fixed side S1 thereafter, the adhesive reaches the winding portions 40A, 40B and 40C of the bobbin thread winding layer 40, and the adhesive quickly infiltrates the winding portions 40A, 40B and 40C. Moreover, since the gap c is formed between the winding portions 40A, 40B, and 40C of the bobbin thread winding layer 40 on the fixed side S1 where the adhesive is applied, the gap c is filled with the adhesive. By (forming a resin pool), the degree of filling of the adhesive in the bobbin thread winding layer 40 is increased, so that the bonding strength between the fishing line guide 7 (leg portion 16) and the fishing rod 1 is increased by the adhesive (resin layer). will increase markedly. In addition, gaps c are formed between the winding portions 30A, 30B, 30C, and 30D of the fixed thread 18 on the fixed side S1 of the needle thread wound layer 30, so that the adhesive does not enter the gaps c. By filling, the fixing strength is further increased, and the pull-out strength of the fishing line guide 7 as a whole is remarkably improved.

Further, since the fixing structure of the fishing line guide 7 of the present embodiment can obtain a high fixing strength (removal strength) in this way, it is necessary to extend the lower thread winding layer 40 as long as in Patent Document 1 described above. There is no need to make the outer diameter of the fixing thread 18 of the lower thread winding layer 40 and the outer diameter of the fixing thread 18 of the upper thread winding layer 30 different. There is also no adverse effect on the appearance seen from the side).

Further, in the present embodiment, the upper thread winding layer 30 and the lower thread winding layer 40 are formed by a single fixed thread 18 in common, and the lower thread is wound along the axial direction of the fishing rod 1 on the fixed side S1. The wound portions 40A, 40B, 40C of the layer 40 and the wound portions 30A, 30B, 30C, 30D of the upper thread wound layer 30 are alternately arranged. With such a configuration, the gap c between the wound portions of the upper thread winding layer 30 and the lower thread winding layer 40 is inevitably and efficiently formed. Since the winding layer 30 and the lower thread winding layer 40 are made of the same single thread, it is not necessary to replace the thread as in the above-mentioned Patent Document 1, and the number of steps in the entire fixing work can be reduced ( fixing work becomes easier).

In addition, the fishing line guide 7 of this embodiment has a bent portion 17 between the ring holding portion 15 and the leg portion 16, and the fixed line 18 at the winding portion 40C of the bobbin thread winding layer 40 closest to the bent portion 17 is greater than the number of windings of the fixing yarn 18 in the other winding portions 40A and 40B. According to such a configuration, the fixing strength is increased at the winding portion 40C of the bobbin thread winding layer 40 closest to the bent portion 17, and breakage at the portion of the upper thread winding layer 30 near the bent portion 17 can be prevented.

FIG. 4 shows a fishing line guide fixing structure according to a second embodiment of the present invention. As shown in the figure, in the fixing structure of the fishing line guide 7 according to this embodiment, the fixing line 18 is wound over the outer surface of the leg portion 16 and the outer peripheral surface of the fishing rod 1 as in the first embodiment. The upper thread winding layer 30 (winding parts 30A, 30B, 30C, 30D; the number of winding parts is not limited to this) and the fishing rod 1 so that the fixed thread 18 passes between the leg part 16 and the fishing rod 1 The lower thread winding layer 40 (in this figure, two more windings 40A, 40B, 40C, 40D, 40E than in the first embodiment; the number of windings is this but not limited to). Similarly, in each of the upper thread winding layer 30 and the lower thread winding layer 40, a gap c is formed between the winding portions of the fixed thread 18 on the fixed side S1.

However, the fixing structure of the fishing line guide 7 of this embodiment differs from that of the first embodiment in that the upper thread winding layer 30 and the lower thread winding layer 40 are formed of separate threads. Since these wound layers 30 and 40 are formed of different yarns, the densely wound portion 30' of the upper thread wound layer 30 is laminated on the densely wound portion 40' of the lower thread wound layer 40 on the non-fixed side S2. It is in a state of In this case, the extended length X1 of the bobbin thread wound layer 40 on the fixed side S1 is greater than the extended length X2 of the tightly wound portion 40' of the bobbin thread wound layer 40 on the opposite side S2 by the gap c. is also longer. Similarly, the extension length Y1 of the needle thread layer 30 on the fixed side S1 is longer than the extension length Y2 of the tightly wound portion 30' of the needle thread layer 30 on the opposite side S2 by the gap c. is also longer.

Also in the fishing line guide fixing structure of this embodiment, the same effects as those of the first embodiment can be obtained.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the fishing line guide has one leg, but the number of legs may be plural. In that case, the fixing structure described above can be applied to each leg. Also, the number of windings of the fixing thread, the number of wound portions, and the like are not limited to those of the above-described embodiment.
