Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a course for a fishing rod wire for attaching a fishing line to a branch line end device used in longline fishing for tuna, bonito, etc.

BACKGROUND ART Conventionally, Utility Model Publication No. 53-53743 has been known as a branch end end device used in longline fishing.
This course is made of synthetic resin, but the grooves of this course have a thin wall and are easily damaged when fishing for tuna, etc., when sufficient impact resistance is required.
It is not possible to draw out the full strength of the set string.

Also, when using a stainless steel metal course,
Galvanic corrosion occurs due to the salt content of the seawater, and once used, red rust appears and is no longer usable. In addition, such a metal course is difficult to create a device due to its hard material, and when an impact load is applied, the course moves along the groove and trough, causing the positions of the far apart legs of the course to change. This may result in the wire being moved and reversed, and the reinforcing effect of the fishing rod wire due to the course may not be produced at all.

Furthermore, Utility Model Publication No. 57-4970 describes a course made of aluminum, but aluminum itself is soft and easily deforms under impact force, and the radius of curvature at the bottom of the course becomes small, causing the course to become unfishable. The reinforcing effect on the thread wire is small, and the fishhook connected to the annular part cannot move freely, causing a decrease in the catch of fish. Furthermore, aluminum courses have the disadvantage that they elute into seawater due to reaction with seawater.

Problems to be solved by the invention The problems to be solved are to improve the impact resistance of the course, to avoid the electric contact phenomenon, and to prevent the course from reversing, and the details are as follows.

In other words, the present invention solves the shortcomings of conventional courses, has good workability for making contraptions for longline fishing, etc., does not suffer from galvanic corrosion even in seawater, and can be used instantly. Even when a large impact force is applied,
To provide a course for a fishing hook wire that does not cause further deformation of the course incorporated in the tackle.

Furthermore, the loop part of the fishing wire and the course of the fishing wire of the present invention are in good contact, so that even when a large impact force is momentarily applied during fishing such as longline fishing, the fishing wire and the fishing wire remain in good contact with each other. It guarantees free movement of the fishhook without causing any deviation from the course of the original fishing wire, movement, or in some cases reversal, etc., and without causing entanglement between the fishing hook and the fishing fishing wire. The purpose of the present invention is to provide a course for fishing line wire, which has a great reinforcing effect and allows safe operation with less risk of breaking the fishing line wire.

Means for Solving the Problems The present invention is made of synthetic resin, and the base has an approximately semicircular ring shape, and has a curved course with a trough-like cross section that has both legs following the base, and the wall thickness of the base is 1.0.
mm or more, and the length of the leg following the base is 2.6 to 4.6 times the radius of curvature of the bottom of the base trough, giving flexibility to the leg. This is a course for fishing wire that has a partially open body shape such as a droop shape, a horseshoe shape, and a partially open egg shape.

Here, the base is the part shown in FIG. 3, and the legs following the base are the parts shown in FIGS. 8 and 8. The wall thickness of the base is shown as D in the same figure, the radius of curvature of the base trough bottom is shown as R in the same figure, the length of the leg is shown as L in the same figure, and the wall thickness of the trough bottom at the leg end is shown as d, respectively.

Next, the thickness of the trough bottoms of both legs is preferably configured to have a value that gradually decreases from the thickness of the base trough bottom as it approaches the tips of the legs. The thickness d of the trough bottom at both leg ends is preferably 0.1 to 0.9 times that of the base trough bottom D.

Since the fishing rod wire course of the present invention is constructed as described above, the base portion, which is approximately semicircular, has a relatively thick trough bottom wall thickness and maintains hardness and rigidity.

Further, both ends following the base have suitably long legs, and preferably have a trough bottom thickness that gradually decreases as it approaches the leg ends, thereby maintaining appropriate flexibility. Therefore, when using the course for the wire of the invention, the two ends of the course of the invention are brought closer together by caulking the wire with a sleeve-like metal fitting to form a loop at the end of the wire. As a contact shape, a closed annular part or a part having a shape close to this is formed in the course for the fishing wire.

Next, the present invention will be explained based on the drawings.

For example, as shown in FIG. The spring 2 is passed through it to form a loop, and the sleeve-like metal fitting 5' is used to swage it. At the other end, the course 3 for fishing hook wire of the present invention is attached, but first, the fishhook 4
The fishhook 4 is suspended from the curved part of the course 3 by passing it through the ring 4a. Next, the sleeve-shaped metal fitting 5 is inserted into the other end of the fishing hook wire 1, and the other end is wound around the outer trough groove of the course 3 in which the fishing hook 4 is suspended, and the tip is again attached to the outer trough of the course 3. The sleeve-shaped metal fitting 5 is inserted into the sleeve-shaped metal fitting 5 and tightened so that the fishing wire 1 and the course 3 are kept in close contact with each other, and the sleeve-shaped metal fitting 5 is brought close to the course 3.
If necessary, the two leg ends of the course 3 are brought into close proximity or in contact with each other, and the sleeve-like metal fittings 5 are swaged to fix the course 3 for the fishing hook wire as a tackle. Note that the above is just one example of the means for making the device, and various changes are possible.

Here, the distance between the fishing wire course and the caulked sleeve-shaped metal fitting 5 does not have to be, but
It is desirable that the diameter of the metal material constituting the ring 4a of the fishhook 4 is at least smaller than, for example, 2.0 mm. As a result, the distance between the two leg ends of the course 3 can preferably be maintained at 0 or approximately 1.5 mm or less.

Next, the fishing wire course 3 of the present invention is made of synthetic resin.
Figure 4 shows the front view, Figure 4 shows the side view, Figure 5 shows the 3rd view.
The cross-sectional view taken along the line A-A in FIG. 6 has a shape shown in the cross-sectional view taken along the line B-B in FIG.

In FIG. 3, the fishing rod wire course 3 of the present invention has a base 7 having a substantially semicircular shape and two legs 8, 8 continuing from the base 7. Here base 7
The wall thickness, especially the trough bottom wall thickness D of the base 7, is 1.0 mm.
or more, and the radius of curvature R of the base trough bottom is 0.4
The length L of the leg is 2.6 to 4.6 times the radius of curvature R of the bottom of the base trough, preferably 0.5 to 0.8 times.
Preferably, it has a length of 3.0 to 4.2 times. The radius of curvature R of the base trough bottom is 2.5 to 8.0.
mm is preferred, and more preferably 3.0 to 5.0 mm.

Here, the wall thickness D of the side wall of the base 7 or the bottom of the trough
is smaller than the above range, the base of the fishing wire course 3 shows flexibility, and when this course is incorporated into a tackle, there is no possibility of slippage or movement between it and the fishing wire. This is undesirable as it may cause a risk of injury.

Next, if the length L of the legs is shorter than the above range, when using a fishing hook wire course as a bait, the flexible distance of both leg ends will be insufficient, so the length of both leg ends will be as long as necessary. It becomes difficult to bring them close or in contact with each other. In addition, if the length L of the leg exceeds the above range, the flexibility of the leg will become too large, which may cause a risk of damaging the close contact between the fishing wire course and the fishing wire. Neither is preferable.

Next, the trough bottom wall thickness D of the base 7 of the fishing wire course 3 maintains rigidity and does not easily deform even if a sudden impact force is applied to the fishing wire course 3 during fishing. Maintains sufficient thickness. On the other hand, both legs 8, 8 are appropriately long,
Preferably, the wall thickness of the trough bottom gradually decreases as it approaches the leg end. After all, the trough bottom wall thickness d at the ends of both legs 8 and 8
is preferably 0.1 to 0.9 of the base trough bottom wall thickness D.
By configuring it so that it has a thickness that is twice as thick, more preferably 0.1 to 0.5 times, even if the course for fishing wire of the present invention is made of synthetic resin, its base 7 is sufficiently strong, and its both legs 8, 8 has appropriate flexibility.

From the above, this proposed fishing wire course 3
When assembling the fishhook into the bait, even if the distance between the ends of the course legs 8 and 8 is somewhat wide or narrow, the ring 4a of the fishhook 4 can be easily passed between the ends of the legs, and the fishhook can be freely attached to the curved part of the course 3. can be located in

When the course 3 of the present invention is incorporated as a device, as shown in FIG.
By caulking as close as possible to the fishing wire course 3 attached to the fishing wire 1, both legs 8, 8 of the fishing wire course 3 are attached.
The ends easily approach or abut to a distance of about 1.5 mm or less, and the fishing wire loop portion 1a and the fishing wire course 3 are brought into close contact.

In addition, as examples of other shapes of the course for the fishing wire of the present invention, a U-shape is shown in FIG. 8, an amadare-shape is shown in FIG.
Examples are shown in Figure 0.

The course constituent material for the fishing rod wire of the present invention uses synthetic resin, and synthetic resins with high impact resistance are particularly preferred; for example, polycarbonate resin, polyimide resin, PPS resin, etc. can be used. Particularly preferred are polycarbonate resins.

Function The fishing wire course of the present invention is made of synthetic resin, and the thickness of the base, which is approximately semicircular, is sufficiently thick, so the fishing wire course of the present invention reduces fishing effort. Even when subjected to impact loads, the base does not undergo deformation. The legs following this base are suitably long, and are preferably constructed so that the thickness of the leg trough bottom gradually decreases as it approaches the end of the leg, so that the legs have appropriate flexibility. When the course of the present invention is incorporated into a device, the ends of both legs can easily approach or come into contact with each other. The invented course built into the device is fixed in close contact with the fishing rod wire.

Example A commercially available polycarbonate resin was used as a course for fishing wire, and the trough bottom curvature radius R of the base 7, which is approximately horseshoe-shaped and approximately semicircular as shown in FIGS. 3 to 6, was 3.8. mm,
The leg length L is 14 mm, and the trough bottom wall thickness D of the base 7 is
2.0 mm, and the wall thickness d of the bottom of the trough at both ends of legs 8 and 8 was 0.6 mm. The fishhook 4 is suspended from the curved part of the course by passing the ring 4a of the fishhook 4 between the ends of both legs of the course. The diameter of the stainless steel wire that makes up the ring 4a of the fishhook 4 is
2.5mm, outer diameter 12mm.

A single thread of vinylidene fluoride with a diameter of 2.0 mm is used as the fishing hook wire, and this wire 1 is inserted into the fixing aluminum sleeve fitting 5, and then the fishing hook is suspended. Wire 1 while keeping it in close contact with the trough of
After inserting the tip of the sleeve-shaped metal fitting 5 into the sleeve-shaped metal fitting 5, the sleeve-shaped metal fitting 5 is brought close to the course 3 until it comes into contact with the course 3, and both ends of both legs 8, 8 of the course 3 are brought into contact with each other. Then, the sleeve metal fitting 5 was caulked while tensioning the fishing wire 1 to form a device.

When long-line fishing for tuna was carried out using the device created in this way as shown in Figure 1, the operation was carried out smoothly and safely for a long period of time.

Effects of the invention As mentioned above, since the invented fishing wire course is made of synthetic resin, it is easy to manufacture and process, and it is free from electric shocks that occur when using metal courses such as stainless steel and aluminum. There are no disadvantages such as the need to replace fishing hooks due to erosion, elution into seawater, etc.

Next, the inventive course for fishing hook wire has a substantially semicircular shape with a sufficiently thick base, so that even if an impact force is applied to the inventive course during fishing, the base will not deform. There is no. In addition, since both legs following the base of the present invention have appropriate flexibility, when the course of the present invention is incorporated into a device, the ends of both legs of the course of the present invention come close to each other or come into contact with each other to form a generally annular portion. The fishing line wire is tightly fixed in the outer trough groove, and even if a large momentary impact force is applied during fishing activities such as longline fishing, the invented course will not shift, move, or turn around with the fishing line. etc. will not occur. Therefore, the course of the present invention always retains the reinforcing effect of the fishing wire.

Further, the ring of the fishhook can freely move within the annular portion constituting the course of the present invention incorporated into the device, but since the positions of both leg ends are narrower than the ring of the fishhook, it will not deviate from the annular portion of the course of the present invention.

In the end, the fishing hook held in the fishing wire course is guaranteed to move freely, and the fear of the fishing wire getting tangled or broken is eliminated, and the original strength of the fishing wire thread is improved. It has become possible to use the fishing wire course of the present invention for long-line fishing etc. stably for a long period of time.
