TW380039B - Fishing line guide for fishing rod and telescopic fishing rod - Google Patents

Abstract

For the habitually used slide type fishing line guide, a resistance will suddenly occur at the front end of target position of the rod and cause excess force for pushing. So, it is very difficult to correctly fix on the target position and the rod body may be broken due to resilience. According to the said problem, the invention is to have the installation portion with rod hole formed and made of synthetic resin. Because the cross section of rod hole is basically of square shape, there are four rod body contact edges of linear shape and those edges are about point-contact with the exterior of rod body. Therefore, when the rod hole is pushed by the rod body, the interval between opposite rod body contact edges will be pressed and expanded so as to deform the rod body. With this deformation, a part of the pressed resistance can be eliminated and the control of pushing force is made easier that the fishing line guide can be easily and precisely stopped at the target position and reduce the chances of rod body damage.

Description

V. Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a sliding-type fishing line guide installed on a fishing rod formed by combining a plurality of fishing rods in a pull-out type. (Known technology) A telescopic fishing rod is a combination of a plurality of rods whose outer diameters are sequentially reduced in the direction of the holding rod toward the tail rod portion. Fishing line guides such as poles or tail poles supporting rods are necessary to use sliding (also called swimming) objects. FIG. 7 shows an example of a conventional draw-out fishing rod. In the same figure, 3-1 represents the tail pole, 3-2 represents the tail pole supporting pole, 3-3 represents the tail pole supporting the secondary pole, and 3-η represents the mother pole. Each of the rod bodies 3 is formed to be tapered toward the front end. The tapered tube is combined with the second and third rods (not shown) to expand and contract each other freely, and the mother rod 3-η is fixed by a roll holder (not shown). A tail rod guide 5 is fixed at the front end of the tail rod 3-1, and a fixed fishing line guide 7 is installed at each of the embedded ends of the tail rod support rod 3-2 and the tail rod support secondary rods 3-3. Tail rod 3-1, tail rod support rod 3-2 and tail rod support secondary rod 3-3. In addition to the tail rod guide 5 and fixed fishing line guide 7, the device is also provided with 1 to 5 degrees. Of the sliding fishing line guide 9. The sliding fishing line guide 9 is made of a metal frame 11, a cylindrical mounting portion 13 installed near one end of the frame 11, and a sliding portion 9 installed near the other end of the frame 11. The wire loop 15 is composed of the mounting portion 13 made of synthetic resin, and the fishing rod through hole 13a as a hole of the mounting portion 13 is circular in cross section. This sliding fishing line guide 9 is a tail rod 3-1, tail rod support rod

Page 5 V. Description of the invention (2) 3-2 and tail rod support secondary poles 3-3 are telescopically freely inserted through the through-hole 13a of the fishing rod. The inner diameter L (see the same figure (B)) of the through hole 1 3 a of the fishing rod is the size where the target position on the corresponding rod body 3 will be relatively pressed in, that is, the fishing line to which the fishing rod 1 belongs when it is used The guide 9 should be fixedly located at a position where it will be relatively pressed in. When fishing rod 1 is used, tail rods 3-1 are shown in the chain line at (A). When rod 3 is pulled out in sequence, all sliding fishing line guides 9 are slid backward to Press and fix at the target position on the pole 3 to which it belongs. (Problems to be Solved by the Invention) In the conventional sliding fishing line guide 9, many problems arise because the cross-sectional shape of the fishing rod through hole 1a is circular. First, when the fishing line guide 9 is slid toward the target position, at a slightly forward position of the target position, the outer diameter of the rod body 3 is the same as the inner diameter of the fishing rod through hole 1 3 a. The son generates a lot of resistance, and pushing forward from there will cause excessive force to be applied to move beyond the target position. Therefore, it is not only difficult to accurately fix the fishing line guide 9 to the target position, but also the consequence that the fishing line guide 9 is pushed by an excessive force, and the rod body is broken due to the reaction force. Further, when the fishing line guide 9 is pressed in by the rod body 3 with an excessive pressing force, it becomes quite difficult to remove the fishing line guide 9 from the pressing position. The method of pulling the sliding line guide 9 from the pressing position is generally to connect the sliding line guide 9 and the sliding line guide adjacent to it.

V. Description of the invention (3) The front end surface of the rod body 3 of the piece 9 is directly in contact with the front end surface of the rod body 3 and is in contact with the front end surface of the rod body 3 together with other sliding-type fishing line guide members 9 that have been decompressed. In addition, as a method of pulling out the sliding line guide 9 from the pressing position, a method in which the sliding line guide 9 is rotated while being pulled out can also be used. The former method will damage the sliding line guide, especially it is easy to become the sliding line guide 9 or the line guide sandwiched between them or the fixed line guide at the impacted end. The reason for the rupture of piece 7, and this method is to adopt the operation method that the rods 3 adjacent to the rod 3 are often thrown out according to the potential. Therefore, in this case, the belonging rod 3 will be broken due to excess force. There are quite a few things. Even with the latter method, the fishing line guide 9 and the rod body 3 may be deformed due to abnormal force, causing the rod body 3 to break, etc., and the danger of causing serious damage is quite high. In the conventional sliding type fishing line guide, the inner circumferential surface of the through hole of some fishing rods is formed with a knurling as shown by element number 17 in FIG. 7 (C). Through this is the knurling 17, which can have a good fixing effect. The ridge line of the knurling 17 is used to clamp the rod body 3 to disperse excessive force, and it is easy to operate in the pushing operation. benefit. However, with the accumulation of the number of uses, the edges of the knurling 17 will gradually become thinner due to friction, and there will be gradual_inaccurate problems in the fixed position. In addition, the smaller the size of the fishing line guide, the more difficult it is to produce the crown crown 17a of the knurling 17 with dimensional accuracy. In fact, the problem of difficulty in manufacturing will occur. In addition, in conventional sliding line guides, a special surface material is used as a method for stopping the rotation of the rod body (the original fair 4-4 5 2 4), Roll the special tape on the target position

V. Description of the invention (4) formula (Japanese Public Sho Sho 6 2-3 9 6 6 5), a method of providing a protruding portion at the target position (Japanese Utility Model Registration No. 2 5 0 3 4 4 1), A method of setting a mountain portion on the surface of a pole (Japanese Patent Application Laid-Open No. 8-1 7 2 9 8 1), a method of installing a polygonal mounting seat on the pole and using it to press in a fishing line guide (Japan Japanese Patent No. 4-4 5 2 9 and Japanese Japanese Patent No. 4-4 1 8 3 0) and a method of providing a soft substance for pressing the fishing line guide on the outer surface of the rod (Japanese Utility Model Registration No. No. 2504855), but these methods all require special treatment of the rod body, and special components must be installed. Of course, in addition to the cost of fishing rods cannot be avoided, the weight of fishing rods will also increase. In addition, there is also a way to keep the fishing line guide in another inner tube to enhance the pressing force on the rod body (Japanese Public Sho Sho 5 9-3 7 2 2), because the structure is quite complicated and the manufacturing cost is quite high. , Its operation is very tedious, it is practically impossible to use on smaller objects. The present invention is provided in view of conventional problems, eliminating the excessive force applied when the fishing line guide is slid to the target position, eliminating the danger of the rod breaking, and allowing the fishing line guide to stop easily and accurately. At the target position, it can fully obtain the pressing force for the rod located at the target position, and the force when pulling the fishing line guide from the target position is relatively small, and it does not require any processing of the rod. The purpose is a fishing line guide and a draw-out fishing rod. (Method for solving the problem) In order to achieve this object, the present invention is a sliding line guide installed on a fishing rod formed by combining a plurality of fishing rods with a pull-out type.

Page 8 V. Description of the invention (5) The line passing portion of the fishing line through hole and the mounting portion containing the rod passing hole through which the fishing rod is inserted; at least this mounting portion is formed of synthetic resin; and the aforementioned fishing rod In the cross-sectional shape of the through hole, there are at least three or more fishing rod contacting edges formed by straight lines or curves; the contacting edge of the fishing rod will be in point contact with the peripheral portion of the fishing rod. -In addition, the present invention is a fishing line provided with a fishing rod combined with a mutual draw-out type and a fishing line provided with a fishing line through hole formed by at least a fishing rod mounted on the fishing rod. The sliding type fishing line guide for a pull-out fishing rod of a sliding line guide formed by a through-hole of a fishing rod passing through a fishing rod and a fishing rod passes through, and at least the mounting portion of the sliding line guide is made of synthetic resin. In the cross-sectional shape of the through-hole of the fishing rod, at least three of the fishing rod contact edges formed by straight lines or curved lines; the contact edges of the fishing rods will be in point contact with the peripheral portions of the fishing rods. In the fishing line guide structured as described above, when the rod body is pressed into the through hole of the fishing rod, the inner surface of the through hole of the fishing rod presses the rod body only in a point-like contact with the portion on the contact side of the rod body. It will deform according to the pressing force of the aforementioned part on the pressing rod body. In particular, since the mounting portion forming the through-hole of the fishing rod is formed of a synthetic resin, this deformation is liable to occur in the entire mounting degree. A part of the resistance generated when the rod body is pushed into the through-hole of the fishing rod by such deformation of the mounting portion is eliminated and absorbed. Therefore, the resistance when the fishing line guide is pushed into the target position on the rod is 0 high, and when the through hole of the fishing rod is circular, the resistance is increased. The force becomes easier to control, thereby eliminating the risk of excessive pressure being applied during press-fitting. So that

V. Description of the invention (6) The sliding operation of the fishing line guide is reasonably performed, so that the danger of the rod damage can be eliminated, and the fishing line guide can be easily stopped at the target position.

In addition, the pressing force of the fishing line guide for the pole body will be sufficiently strong due to the reaction force generated by the mounting portion, so the position at the target position is quite stable. This compression is then less affected by the roughness of the outer surface of the rod. That is to say, the roughness of the outer surface of the rod body will have a considerable degree of error due to the same material used and the same degree of painting, but the pressing of the fishing line guide and the rod body according to the present invention is performed by point contact. , Will not be limited by the roughness of the outer surface of the rod, and its pressing force is not prone to errors. Q In addition, since the pressing of the fishing line guide and the rod is performed by point contact, the force when the fishing line guide is pulled out from the target position is concentrated at the point where the point contact occurs, and the required force is relatively small. . This description was verified by the inventors through a proxy test described later. Because the force when pulling out the fishing line guide from the target position can be completed with a small force, the danger of rod damage can be greatly eliminated, especially the danger of small rods such as tail rods and tail rod holding rods. The method used in the present invention is to make the cross-sectional shape of the through-hole of the fishing rod into a basic shape with multiple angles. This shape does not have a particularly complicated structure like knurling. While it is easy to make, it is more like a tail rod. The dimensional accuracy of various parts in a small-sized object generally using a fishing line guide can also be easily produced. In addition, in the present invention, there is no need to perform any processing on the rod body, and it is not necessary to install special objects on the rod body or the fishing line guide, so there is no concern that the manufacturing cost of the fishing line guide or the rod becomes high. .

Page 10 V. Explanation of the invention (7) In the implementation of the present invention, the number of the contact sides of the fishing rod through hole may be 3 or more. If the contact edge is set to an even number such as 4, 6, etc., the fishing rod through hole The dimensional accuracy can be obtained by the generation of the dimensional accuracy between the contact sides of the two rod bodies of each other. Therefore, in the manufacture of the mold and the like, the manufacturing operation of the fishing line guide can be carried out more easily. The cross-sectional shape of the through-hole of a fishing rod is basically preferably a regular triangle, a square, a regular hexagon, a regular octagon, or a regular dodecagon. The sides, that is, the contact sides of the rod, do not have to be straight lines, as long as they conform to the Of course, even if the outer surface is a point contact, it may be curved. In addition, the cross-sectional shape of the through-hole of the fishing rod may be a regular shape such as a regular quadrangle. The chamfered part is also a chamfered part formed by the contact sides of two adjacent poles. The chamfered part is in contact with the pole. By filling, it is possible to avoid the formation of a noticeable thin meat portion at the mounting portion, and it is possible to prevent a reduction in strength. (Embodiment of Invention) Hereinafter, a fishing line guide 21 for a sliding fishing rod according to an embodiment of the present invention will be described with reference to the drawings. First, the structure of a fishing line guide is demonstrated. The fishing line guide 2 1 is only composed of the main body 2 3 and the guide ring 2 5. In the main body 2 3, the fishing line passes through the step 2 7 and the mounting portion 2 9 is made of synthetic resin (nylon, polycarbonate, polyaldehyde resin). Etc.). The fishing line passing portion 27 is formed by cutting the diameter of the cylinder whose length in the axial direction is shorter in proportion to the diameter of the inclined surface that crosses the axis obliquely. The through hole is the fishing line through hole 2 7 a. The front end of this fishing line through hole 2 7 a,

Page 11 V. Description of the invention (8) That is, the part of the fishing line guide ring 25 which has the full circumferential part and the most surrounding wall surface is fixed in an embedded shape. The fishing line guide ring 25 is made of a hard material such as ceramics, and the fishing line guide ring 25 is passed by the fishing line 31. The slanted surface 2 7 b of the fishing line passing portion 27 has a function of releasing the slanted surface for sliding the entangled fishing line 31 outward. The mounting portion 29 is cylindrical, and its axis is located parallel to the axis of the fishing line passing portion 27. A portion of the surrounding wall surface is also a portion of the surrounding wall surface of the fishing line passing portion 27. The through hole of the mounting portion 29 is a fishing rod through hole 33, and the rod body 3 5 passes through this fishing rod through hole 33. The basic shape of the through-hole 33 of the fishing rod as seen from its cross section is a square (refer to FIG. 3). The size of this square is equal to the predetermined target position P (refer to FIG. 2) of the rod body 35. The outer diameter of the circle S is slightly smaller. Therefore, the fishing rod through hole 3 3 is provided with four linear rod contact sides 37 corresponding to the four sides of the square. Then, the connecting portion 3 9 connecting the two adjacent rod contact sides 3 7 of each other is formed into an arc shape. The center of the arc of this connecting portion 39 is the same as the center of the circle S, and its curvature radius is larger than that of the circle S. The radius of curvature is slightly larger. In the method of forming the connecting portion 39, the four corners of the square are filled without touching the circle S. The fishing line guide 21 is constituted as described above. The fishing line guide 2 1 will pass through the rod body 3 5 and pass through the fishing rod through hole 3 3 and will be held on the belonging rod body 35 in a state more forward than the target position @ 棋 位置 not fixed to be free Status. The rod body 3 5 and other rod bodies are stored in this state. From this free state, when the fishing line guide 2 1 is slid backward to the target position, the rod body 3 5 will press the fishing rod through hole 3 3

Page 12 5. Description of the invention (9) The position of the fishing line guide is fixed. That is, when the fishing line guide 21 moves backward to a slightly forward position of the target position (a position where the outer diameter of the rod body 35 is the same as the inner diameter of the fishing rod through hole), the fishing rod through hole 33 is counted forward. All four rod-body contacting edges 37 will come into contact with the peripheral portion of the rod body 35 to generate resistance during movement. This contact is made at the point where the rod touches the edge 3 to 7 in the middle. From this state, move the fishing line guide 2 1 further to the rear and push the rod body 3 5 against the fishing rod through hole 3 3, and the interval between the contact sides 37 of the rods facing each other will be compressed and expand to make the body 2 3 Deformed. This deformation mainly occurs in the mounting portion 29, and as a result, a part of the aforementioned resistance is eliminated. Therefore, when the fishing line guide 21 is pushed into the target position on the rod 35, the high rise of the resistance can be suppressed to a certain degree, and the force exerted by this pushing will become easier to control. Therefore, it is possible to It is easy to accurately stop the fishing line guide 21 at the target position. Then, by the reaction force generated by this deformation, the contact side 37 of the rod presses the rod 35, and the pressing force is used to fix the fishing line guide 21 at the target position. Since the pressing of the fishing line guide 3 3 and the rod body 3 5 is performed by point contact, the force when the fishing line guide 21 is pulled out from the target position will be concentrated at the point where the point contact occurs. The required force is relatively The ground is relatively small. In order to verify this result, the inventors performed a simulation test of the extraction pressure by using a test sample described below. The simulation sample is a circular plate with an outer diameter of 33 mm and a thickness of 6 mm, which is made of the same material as the main body 23. This is a square hole (a diameter of 20 mm) that is the same as the through hole 33 of the fishing rod. A square hole) is used as a test area, and a circle with an inner diameter of 20 mm will be formed.

Page 13 V. Description of the invention (10) The object with a shaped hole and the knurled hole forming a dome circle with a pitch of 20 mm are used as comparison areas, respectively. The test method uses a certain position on the center of the metal as the target position. After reaching this target position, it is pushed forward by a pressure gauge through manual operation from the press-in state, and the pressure at the time of extraction from the target position is measured. The test results are shown in Table 1. Table 1 Hole shape of test sample Extraction pressure (kg) Test Square 16.32 area than circle 22.78 Compared with knurled hole 17.72 The "extraction pressure" shown in Table 1 is the average value of the data obtained by performing the aforementioned measurement 10 times. It can be known from the table that the extraction pressure and the roll formation in the test area

Page 14 V. Description of the invention (11) The comparison area of the perforations is reduced by about 8%, and the comparison area of the round holes is reduced by about 30%. This result is obtained through simulation tests. Although the actual line guide 21 is not necessarily the same, the difference is not so great. As mentioned above, the corners of the through-hole 33 of the fishing rod are filled to the extent that they contact the pole body 35, and unlike the case where the corner is maintained at the right angle, the mounting portion 29 does not form a local Thin meat department. Therefore, compared with the circular hole, the cross section of the fishing rod through hole 33 becomes somewhat larger, and the corner can be filled to reduce the increase in the thickness of the thin meat as much as possible, so it can prevent the decrease in h intensity. In order to prevent the local pressure from being concentrated due to deformation. ^ Figures 4, 5, and 6 show other forms of fishing rod through holes 33 respectively. In the fishing rod through hole 3 3 A shown in FIG. 4, the basic shape seen in the cross section is a regular hexagon. Therefore, six linear rod contact sides 37 corresponding to the six sides of the regular hexagon are provided, and the connection portion is provided. 3 9 is formed in an arc shape. In addition, in the fishing rod through hole 3 3 B shown in the figure, the basic shape seen in the cross section is a regular triangle. Therefore, three straight rod bodies corresponding to the three sides of the regular triangle are provided to contact the sides 3 7 to connect them. The portions 39 are also formed in an arc shape. In the fishing rod through hole 3 3 C shown in the figure, the basic shape seen in the cross section is a square, and the four rods corresponding to the four sides of the fishing rod are formed in a gentle curve. The rod-contacting edge 37 of this shape makes approximately point p contact with the rod 35. The foregoing is a detailed description of the embodiment of the present invention. The specific structure is not limited to this embodiment.

P.15 5. Design changes of the description of invention (12) are included in the present invention. For example, in the embodiment, although the fishing line passing portion and the mounting portion are integrally formed, they may be formed separately, and the fishing line passing portion does not need to be formed of a synthetic resin. (Effects of the Invention) As described above, in the fishing line guide and the draw-out fishing rod of the present invention, the resistance when the line guide is slid to the target position on the pole is re-fished. When the through-hole of the rod is round, it will not rise suddenly, so there is no danger of applying excessive force when performing this sliding. Therefore, while the fishing line guide can be moved reasonably, the risk of damage to the rod can be reduced, and the fishing line guide can be easily stopped at the target position accurately. & In addition, the pressing force of the fishing line guide for the rod body will be sufficiently strong due to the reaction force generated by the rod passing through the < section. In addition, the pressing force of the fishing line guide and the rod body is connected to the point. The contact is performed, and the force when the fishing line guide is pulled out from the target position is concentrated on the point where the point contact occurs, and the required force is relatively small. Since the force when pulling out the fishing line guide from the eye position can be completed with a small force, the danger of rod damage can be largely eliminated, especially the danger of small rod damage. According to the invention in item 2 of the scope of patent application, the dimensional accuracy of the through-hole of the fishing rod can be obtained from the dimensional accuracy between the contact edges of the two rod bodies of each other. Therefore, in the manufacture of the mold, etc. The manufacturing operation can be performed more easily. p According to the invention in item 3 of the scope of patent application, it is possible to avoid the formation of a noticeable thin meat portion on the mounting portion, and to prevent a reduction in strength.
