Description

  The present invention relates to an auxiliary tool used when a relatively thin fishing line (line) is knitted and connected around the surface of a relatively thick fishing line (leader). In particular, the present invention relates to an auxiliary tool that can easily create an FG knot (described later).

  As the fishing line (line) to be wound around the reel, a thin line is used because long-distance can be thrown and water resistance is low. A thick thread (leader) is connected to the tip of this thread to prevent the thread at the tip from rubbing against rocks or seaweeds when fish catches.

As a line, it is necessary to be flexible, thin and strong, and in recent years, a polyethylene-based line having a tensile strength more than three times that of a conventionally used nylon thread is becoming widespread. However, this polyethylene line also has the following disadvantages.
(1) The surface is slippery and slippery.
(2) Since the thread is too thin, there is a risk of cutting the hand with the thread if it is pulled with bare hands during the connection.
(3) The strength at the knot is weak.

Moreover, there are the following problems in connecting the leader to the polyethylene line.
(1) In order to cope with the tensile strength of polyethylene-based lines, nylon or fluorocarbon yarns having a diameter of about 3 to 4 times the line are often used as leaders. Thus, when the diameters of both are extremely different, the conventional general connection method is not suitable.
(2) Since the surface of the polyethylene line slips, the leader can be easily removed by the conventional connection method.

  Therefore, there has been proposed a connection method (FG knot) in which the line is knitted about 10 to 15 turns around the surface of the leader, and the line is bitten into the surface of the leader by strongly pulling the knitted line (see Non-Patent Document 1). ). This method is a good connection method because the connection strength is high and the stitches are small.

  To create an FG knot without using a tool, first hold the polyethylene line with both hands and knit it on the surface of the leader. Then, hold the both ends of the knitted polyethylene line and pull it strongly to bite (knit) the line yarn into the surface of the leader. In other words, after knitting the line, it is necessary to pull the line with a strong force. However, as described above, since the polyethylene line is thin and slippery, the hand slips and sufficient knitting strength cannot be obtained, and since it is dangerous with bare hands, a glove-like protector is required.

  Also, an FG knot connection aid has been proposed (see, for example, Patent Document 1). This auxiliary tool has a main body having an elastic arm provided in a V shape, and a body hook attached to the body. Fix the body to a fixed object such as a pillar (or the operator's feet) and attach the body hook to the body. One end of the leader is fixed to the stopper on the main body, and the leader is bridged with tension between the stopper and the body hook. Then, the line is stretched between the ends of the elastic arm with tension, and the line is knitted on the surface of the leader while moving the stopper and each elastic arm.

  This auxiliary tool requires a work for fixing the main body, or a body fit is attached to the body. In addition, it is troublesome to perform such work in the middle of fishing outdoors or on a ship.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a fishing line connection aid that can make an FG knot in a simple procedure.

  The fishing line connection assisting tool of the present invention is an auxiliary tool that is used when knitting a wire that is a relatively thin fishing line around the surface of a leader that is a relatively thick fishing line, and includes a permanent magnet portion. A member formed with a threading hole A, and a B member including a material part attracted to the permanent magnet portion of the A member, and formed with a threading hole B. The A member and the B member The threading hole A and the threading hole B are aligned, the leader is passed through the threading hole that is in communication, and the line is slid between the mating surfaces of the two members. It is characterized in that it can be knitted in a state where tension is applied to its surface.

  In the present invention, the line is sandwiched between the mating surfaces of the magnets of the attracted members, so that the line can be pressed against the surface of the leader in a tensioned state without loosening. And when forming a fishing line with FG knot, a line can be made to bite a leader firmly for every stitch in a knitted body. Therefore, the pulling process after knitting can be omitted as compared with the conventional case where the line is once knitted loosely along the leader and then pulled with a strong force. Further, since the pulling force for each stitch may be small, the finger is not damaged by the line. Further, as will be described in detail later, the stitches are automatically formed so as to be arranged in order along the leader, so that it is not necessary to use nerves so that the stitches do not shift. Furthermore, since the structure is simple and small, and a fixed object such as a pillar is unnecessary, it can be easily used at a fishing spot. In particular, since a permanent magnet is used, it can be used outdoors.

  In the present invention, the diameters of the threading hole A and the threading hole B are different, the diameter of the small threading hole is larger than the diameter of the leader, and the diameter of the large threading hole is around the leader. The diameter is preferably larger than the diameter of the FG knot on which the line is knitted.

  Since the diameters of the two threading holes are different, a corner is formed between the mating surface of the magnet formed with the small diameter threading hole and the side wall of the large diameter threading hole. By pulling the line at this corner, the pulling force is concentrated on the corner, so that the line can be firmly bitten into the surface of the leader. Further, this corner portion is separated from the mating surface of both magnets in the direction of the large-diameter threading hole by a difference in radius between both threading holes. And then, it is the mating surface of the two magnets that the line is wound around the leader. That is, since the stitches sequentially advance through the large-diameter threading hole, the stitches can be formed so as not to overlap.

  In the present invention, the permanent magnets have a magnetic force such that the threading holes are arranged on the same core, and have an automatic alignment function in which the threading holes of both magnets are arranged on the same core. If so, the aforementioned corners can always be formed. Specifically, circular permanent magnets can be embedded in both members, and a threading hole can be formed in the center of each permanent magnet.

In the present invention, it is preferable that one of the A member and the B member is relatively small and has a circular planar shape, and the other is relatively large and has an elliptical planar shape.
By making the planar shape of one of the A member or B member into an oval shape, it is easy to hold it with four fingers on the palm of a person, and firmly hold the A member and B member while pulling the line can do.

  In the present invention, if one of the A member and the B member is provided with an indication that indicates the direction in which the lines intersect, at the intersection of each unit (knitting, knot) of the knitted body The direction of crossing can be instructed so that the main line portion and the tip end portion of the line alternately overlap each other. For this reason, it is possible to easily work without losing the direction of crossing every time a stitch is made.

In the present invention, it is preferable to further include a pulling / twisting jig for the line.
If the line is fixed to the jig in a loop shape, the line can be pulled safely and easily. Further, if the jig can be stored together with the A member and the B member, the jig can be prevented from being lost.

  As is clear from the above description, according to the present invention, an FG knot can be made by a simple method and an auxiliary tool having a small and simple structure can be provided. Since this auxiliary tool has the line firmly bite into the leader for each stitch in the FG knot, one pulling force may be small. Further, since the stitches are automatically formed so as to be arranged in order along the leader, it is not necessary to use nerves to prevent the stitches from shifting.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view showing a fishing line connection aid according to an embodiment of the present invention.
2A and 2B are diagrams showing the structure of the connection assisting tool in FIG. 1 (excluding the line pulling jig). FIG. 2A is a plan view and FIG. 2B is a longitudinal sectional view.
The connection assisting tool 1 includes an A member 10 and a B member 20 that can be attracted by a magnetic force. Furthermore, as will be described later, a jig 30 for knitting a line is provided.

  The A member 10 includes a disk-shaped resin main body 11 and a disk-shaped permanent magnet 12 embedded in the main body 11. A horizontal surface (mating surface) 12 a of the permanent magnet 12 is exposed from the lower surface of the main body 11. The material of the permanent magnet 12 is, for example, a ferrite magnet, and the magnetic flux density is around 1000 gauss. A threading hole 13 perpendicular to the mating surface 12 a passes through the main body 11 in the center of the permanent magnet 12. The diameter of the threading hole 13 is the maximum diameter of the leader that can be used with the magnet, and is 0.8 to 1.0 mm as an example. The hole 13 extends toward the opening on the main body side.

  The B member 20 includes a resin-made main body 21 whose planar shape is an ellipse, and a disk-shaped permanent magnet 22 embedded in the main body 21. One horizontal surface (mating surface) 22 a of the permanent magnet 22 is exposed from the upper surface of the main body 21. In this example, the permanent magnet 22 has the same dimensions as the permanent magnet 12 of the A member 10 and the material is the same as that of the permanent magnet 12 of the A member 10. A threading hole 23 perpendicular to the mating surface 22 a passes through the main body 21 at the center of the permanent magnet 22. The diameter of the threading hole 23 is larger than the diameter of the threading hole 13 of the A member 10, and is the maximum diameter of an FG knot made by a leader and a line that can be used with the magnet, and is 1.5 to 2 mm as an example. . The threading hole 23 extends toward the opening on the main body side.

  Further, arrows 25 extending in the short direction of the main body 21 are marked on both sides of the permanent magnet 20 on the upper surface of the main body 21. Each arrow 25 points in the same direction. Details of the purpose of the arrow 25 will be described later. A recess 26 is formed on the upper surface of the main body 21 on the outside of each arrow 25. As will be described in detail later, a part of the jig 30 is accommodated in the recess 26.

  When the permanent magnet 12 of the A member 10 and the permanent magnet 22 of the B member 20 are brought close to each other, the mating surfaces 12a and 22a of the two magnets 12 and 22 are attracted by the magnetic force. Then, the threading hole 13 of the A member 10 and the threading hole 23 of the B member 20 automatically communicate with each other on the same core.

Next, the operation / principle for forming an FG knot with this connection aid will be described.
3, 4, and 5 are diagrams schematically illustrating a method of making an FG knot. Hereinafter, the vertical direction refers to the vertical direction of the drawing.
First, the mating surfaces 12a and 22a of both the magnets 12 and 22 of the A member 10 and the B member 20 (only the mating surface 12a of the permanent magnet 12 of the A member 10 is shown in the figure, but the mating of the permanent magnets 22 of the B member 20 is shown. The surface 22a is also on the same surface as the mating surface 12a), and the both threading holes 13, 23 are communicated on the same core. Hereinafter, the threading hole 13 of the A member 10 is also referred to as a small diameter threading hole, and the threading hole 23 of the B member 20 is also referred to as a large diameter threading hole.

  Then, as shown in FIG. 3A, the leader 100 is passed through the small-diameter and large-diameter threading holes 13, 23 communicated with each other. Next, as shown in FIG. 3B, the line 101 is inserted while sliding between the mating surfaces 12 a and 22 a of both the magnets 12 and 22, the middle of the line 101 is hung on the leader 100, and the outer circumference of the leader 100 Wrap it in a V shape against the surface. In the following description, the part on the base end side from the position of the line 101 hung on the leader 100 is called the main line part 101a, and the part on the tip end side is called the tip part 101b.

  Next, as shown in FIG. 3C, the V-shaped main line portion 101a and the tip portion 101b are rotated (twisted) by 180 ° on the mating surface 12a of both magnets. Thereby, the main line part 101a and the front-end | tip part 101b cross | intersect. And the main line part 101a and the front-end | tip part 101b are pulled as it is. Then, the leader 100 moves downward in the large-diameter threading hole 23, and eventually the mating surface 12 a of the permanent magnet 12 of the A member 10 and the side wall 23 a of the line through hole 23 of the permanent magnet 22 of the B member 20. Hit the corner in between.

  When this state is viewed in cross section, it is as shown in FIG. When the main line portion 101a and the leading end portion 101b are further pulled, the wound line 101 is pressed against the surface of the leader 100 and bites into the surface of the leader 100 to form the first stitch N1. When the leader 100 is pressed against the corner by the line 101 in this way, the pulling force of the line 101 is concentrated on the corner, so that the leader 101 can bite the line 101 with a stronger force. Since both magnets 12 and 22 are attracted, both threading holes 13 and 23 remain concentric even during the pulling operation. That is, the angle between the mating surface 12a of the permanent magnet 12 in which the small-diameter threading hole 13 is formed and the side wall 23a of the large-diameter threading hole 23, which is caused by the difference in diameter between the two threading holes 13 and 23, is always. Is formed. Further, even if the force for pulling the line 101 is released, the line 101 is not loosened by being sandwiched between the magnets 12 and 22, so that the state where the line 101 bites into the leader 100 is maintained.

  By pulling the line 101, the A member 10 and the B member 20 are pressed against each other so that the leader 100 does not enter between the mating surfaces 12 a and 22 a of the permanent magnets 12 and 22. It is preferable to adjust. Further, since the line 101 and the leader 100 intersect at a right angle, the leader 100 is pulled by the line 101 and enters between the mating surfaces 12a and 22a of the two magnets 12 and 22 unless the line 101 is pulled with a great force. There is nothing.

  Further, as shown in FIG. 4A, the first stitch N1 has a large-diameter threading portion from the mating surfaces 12a and 22a of the two magnets by the difference in radius between the two threading holes 13 and 23. It is displaced in the direction of the hole 23.

  Next, the main line portion 101a and the tip end portion 101b of the line are moved in opposite directions between the mating surfaces 12a and 22a of the two magnets with the two threading holes 13 and 23 as the center. Then, as shown in FIG. 4B, the leader 100 moves upward in the threading holes 13 and 23 that communicate with each other, and the main line portion 101a and the tip portion 101b of the line are aligned surfaces 21a of both magnets. 22a, hits the leader 100. As described above, the first stitch N1 is displaced from the mating surfaces 12a and 22a of the two magnets in the direction of the large-diameter threading hole 23. Therefore, the first stitch N1 extends from the stitch N1 in the direction of the small-diameter threading hole 13. The line 101 hits the leader 100 at a distant position. Then, the main line portion 101a and the tip end portion 101b of the line are wound around the leader 100 in a V shape (see FIG. 3B).

  Next, the main line portion 101a and the tip end portion 101b of the line are crossed by twisting at the mating surfaces 12a and 22a of both magnets. When the main line portion 101a and the tip end portion 101b are pulled upward, as shown in FIG. 4C, the leader 100 has a mating surface 12a of the permanent magnet 12 of the A member 10 and a permanent magnet 22 of the B member 20. It hits the corner between the side wall 23a of the line through hole 23. This corner is on the opposite side of the corner forming the first stitch N1 shown in FIG. Further, when the main line portion 101a and the front end portion 101b are pulled strongly, the wound line 101 is pressed against the surface of the leader 100 and bites into it. As a result, the second stitch N2 is continuously formed on the small-diameter threading hole 13 side of the first stitch N1.

When the V-shaped main line portion 101a and the front end portion 101b are twisted and intersected with the mating surfaces 12a and 22a, the main line portion 101a and the front end portion 101b are alternately overlapped with each other.
FIG. 6 is a diagram schematically illustrating a state in which the line is knitted on the surface of the leader.
As shown in the figure, the tip 101b overlaps the main line 101a at the intersection C1 of the first stitch N1. And, at the intersection C2 of the second stitch N2, the main line portion 101a overlaps the tip portion 101b. Thus, the strength of the stitches N can be made uniform by alternately overlapping the main line portions 101a and the tip portions 101b. Further, the intersection C is formed alternately on the back side and the front side of the leader 100 in FIG. This also makes the strength of the stitches N uniform.

  By repeating the above operations 10 to 15 times, an FG knot can be created as shown in FIG. In this method, even during the pulling operation, the line 101 is always sandwiched between the mating surfaces 12a and 22a of the two magnets, so that the tension is not released. Further, the step between the small-diameter threading hole 13 and the large-diameter threading hole 23 (the angle between the mating surface 12a of the magnet 12 and the side wall 23a of the large-diameter threading hole 23) is maintained by the magnetic force of the permanent magnets 12 and 22. Therefore, as described above, the stitches N can be continuously formed without overlapping. Also, instead of knitting the line 101 once to the leader 100 and pulling in the line 101, the stitches N (parts where the line bites into the leader, knots) are created one by one, so with less force That's it.

Based on the principle described above, an FG knot can be created using only the A member 10 and the B member 20. However, in actual work, it is preferable to use the above-described jig 30 for knitting while pulling a line. Next, a method for creating an FG knot using this jig will be described.
7, 8, 9, and 10 are diagrams for explaining a method of creating an FG knot using a line pulling jig.
11A and 11B are diagrams for explaining the crossing state of the lines in FIG. 8, FIG. 11A shows the state of FIG. 8A, and FIG. 11B shows the state of FIG.
As shown in FIG. 1, the jig 30 includes an annular handle portion 31 and two hook portions 32 provided on the outer peripheral surface of the handle portion 31. First, as shown in FIG. 7A, the line 101 is hooked and fixed to both hooks 32 of the jig 30, and a loop is formed between the hooks 32. Further, the permanent magnet 12 of the A member 10 and the permanent magnet 22 of the B member 20 are attracted, and both the threading holes 13 and 23 are communicated. Next, as shown in FIG. 7B, the leader 100 is passed through the threading holes 13 and 23 of the adsorbed A member 10 and B member 20.
A notch 15 that extends radially with respect to the threading hole 12 may be provided on the upper surface of the main body 11 of the A member 10. In these notches 15, the portions coming out of the leader holes 13 passed through the threading holes 13 enter.

  Next, as shown in FIG. 8A, the adsorbed A member 10 and B member 20 are placed on four fingers other than the thumb of the left hand. In this example, the arrow 25 of the B member 20 faces the tip of the hand. Then, the loop of the line 101 formed on the jig 30 is inserted between the mating surfaces 12 a and 22 a of both magnets through the A member 10. Next, holding the handle portion 31 of the jig 30 while sandwiching the A member 10 and the B member 20 between the thumb and the other four fingers, the direction perpendicular to the arrow 25 of the B member 20 (see FIG. Pull down (to the lower right). Then, the loop slides between the mating surfaces 12a and 22a and wraps around the leader 100 passed through the threading holes 13 and 23 as shown in FIG. As a result, the state shown in FIG. As shown in the figure, when the A member 10 is pressed with the thumb of the left hand, the leader 100 drawn out from the A member 10 is inserted into the notch 15 on the upper surface of the A member 10.

8A, the jig 30 is turned upside down with respect to the mating surfaces 12a and 22a of both magnets according to the arrow 25 of the B member 20. Thereby, as shown in FIG. 8B, and more easily shown in FIG. 11B, the main line portion 101a and the tip portion 101b intersect each other. Then, the jig 30 is pulled more strongly. As a result, the state shown in FIG. 4A is obtained, and the line 101 bites into the leader 100 to form the first stitch N1.
When the line 101 is pulled against the reader 100 with a strong force, the A member 10 and the B member 20 through which the leader 100 is passed are sandwiched between the thumb and the other four fingers. At this time, since the B member 20 is oval and can be easily fixed with four fingers, the A member 10 and the B member 20 can be held firmly and stably.

Next, as shown by the chain line arrow in FIG. 8B, the jig 30 is turned over and moved to the opposite side with respect to the both threading holes 13 and 23. Then, the main line portion 101a and the tip end portion 101b of the line move in the opposite directions between the mating surfaces 12a and 22a of the two magnets with the two threading holes 13 and 23 as the center. As a result, as shown in FIG. 9A, the main line portion 101a and the tip portion 101b are wound around the line 100, and the state shown in FIG. 4B is obtained. 9A, the jig 30 is turned upside down on the mating surfaces 12a and 22a of the two magnets according to the arrow 25 of the B member 20. At this time, the direction to be reversed is opposite to the previous direction (the stage in FIG. 8A). Thereby, as shown in FIG. 9B, the main line portion 101a and the tip portion 101b intersect each other. Then, the jig 30 is pulled more strongly in the upper left direction in the figure. As a result, the state shown in FIG. 4C is obtained, and the line 101 bites into the leader 100 to form the second stitch N2.
If this operation is repeated 10 to 15 times, an FG knot can be created as shown in FIG. Finally, as shown in FIG. 10, the line 101 is connected with a half hitch.

  When the jig 30 shown in FIGS. 8A and 9A is turned upside down, the B member 20 is turned over in the direction of the arrow 25, so that the intersection of the stitches N as described in FIG. In C, the main line part 101a and the front-end | tip part 101b of a line can be piled up alternately. Therefore, it is possible to work without losing the direction to turn over.

  The A member 10, the B member 20, and the jig 30 can be assembled together. In this case, the hook 30 is inserted into the recess 26 on the upper surface of the B member 20. Then, the permanent magnet 12 of the member 10 is attracted to the permanent magnet 22 of the B member 20 through the handle portion 31 of the jig 30 through the A member 10.

FIG. 12 is an exploded perspective view showing a fishing line connection aid (excluding jigs) according to another embodiment of the present invention.
Similar to the connection assisting tool 1 shown in FIG. 1, the connection assisting tool in this example includes an A member 10 and a B member 20 that are attracted by a magnet. In this example, two rectangular parallelepiped permanent magnets 12 and 22 are embedded in each member. Also in this case, when the permanent magnets 12 and 22 are attracted, the threading holes 13 and 23 of the respective members communicate with each other on the same core.
