Description

The present invention relates to a fishing hook for a krill bait for sea fish used in coastal and offshore single fishing fisheries, etc. is there.

The name of each part of a fishing hook conventionally used for fishing will be described with reference to FIG. 2 mainly referring to Non-Patent Document 1 and Non-Patent Document 2. In the following, the orientation of this figure will be explained and illustrated with the front. Usually, there is a shape part called ear 2 (or chimoto, tataki, eye, kale, etc.) at the end of the shaft 3 (or stem, shank, etc.) to which the fishing line 10 is coupled, and on the opposite side, the needle tip Out of about 180 degrees of bending (curved part, bend, etc.) towards 7, waist bending 4 (waist, hip bending, etc.) sharing about half of the span, and then the remaining half of the forward bending 5 ( And the like, and finally the needle tip 7 (point etc.). Between the tip bend 5 and the needle tip 7, jaws 6 (modulation, burrs, barbs, etc.) are provided on the inside, outside, or both sides of the curve as required. The main shape of the ear 2 of the fishing hook for bait fishing is the Kashiwagi / round ear 2a having a wide surface that is flattened facing the side of the side of the roller 8 and a relatively narrow surface facing the surface of the roller 8 by crushing and removal processing. There is a hole Sarae ear 2c having a through-hole, a pipe-attached (hole Sarae) ear 2d with the end of the shaft 3 bent round so as to have a hole (including a substantially hole) facing the ft roller 8 and the like. The jaw 6 is basically provided in the flat roller 8 or a plane including a curve. The distance between the needle tip 7 and the shaft 3 is referred to as “ft roller 8”. When the horizontal distance is large, the roller is wide, and when the distance from the curved portion is large, the roller is deep. In order to stop feeding, there are cases where one or two kens 9 are usually provided on the side of the shaft 3 opposite to the shaft 8. Basically, the ken 9 is also provided in the same plane including the previous wing roller, because this is a position that does not pierce the finger when holding the fishhook 1 when the fishing line is coupled. Further, in the literature examples described later, there is an example in which the ken 9 is provided on the side of the ft roller 8 or on the inside of the curve (between the forward curve 5 and the hip curve 4), and this is also in the plane. The entire configuration of FIG. 2 is called a fishhook 1 and is hereinafter simply abbreviated as a fishhook.

Among the effects and shape classifications of the above-mentioned prior art document information, there are many which are compounded, and there are many cases where there is no description of the effects especially for the design, so this is a map by the inventor's arbitrary decision.

Among the unpublished related applications that do not circulate the fishing line 10 around the shaft 3, improve the krill penetration at the coupling portion 15 and the two ears, and enable this special krill series mounting / use method. The following documents are examples of the structure that must be partially used.

A krill 20 shown in FIG. 3 is one of plankton (floating organisms), and is a crustacean of the soft knot sub-net krillidae, and there are about 80 to 90 kinds in the whole ocean according to the encyclopedia. Unlike decaps such as shrimp, it has a more primitive body structure such as exposed sharks. Since it can only be supplied as an inexpensive fishing bait with a certain size and abundantly produced, large and medium-sized ones collected mainly by special ships in the Antarctic Ocean etc. are raw or boiled And frozen and supplied as fishing bait. The name of each main part is based on the following non-patent document 3. Further, according to Non-Patent Document 4, the advantages are the fish collection effect, soft and good bite, low specific gravity, and nocturnal light, and the disadvantages are soft and incapable of long throwing and fast food loss.

Naoyuki Toyoda "Is it licked by fish?" Kosaido Publishing November 20, 1992 First edition, September 10, 1993, 5th edition P81 Figure II Chapter of "Tsurijinsha" "Sea and river fishing food encyclopedia" Tsuritinsha Co., Ltd. December 15, 1981 First edition 1989 edition P38 Krill section

Regarding how to attach krill to a so-called device that combines a fishing hook and fishing line, refer to Non-Patent Document 4 and Non-Patent Document 5 and Non-Patent Document 6 below. First, tail 20i (20h, 20j, 20k, etc.) is cut or cut into pieces as shown in FIG. This is referred to as krill 25 in the present invention. As shown in FIG. 5, when the abdomen of the krill 25 is threaded or stitched so that the abdomen of the krill 25 is on the side of the side of the heart, It becomes a so-called belly. The number of times of sewing may be plural, and so on. If the krill 25 is pierced or stitched as shown in FIG. Removing the tail 20i, which is the basic pretreatment, is essential to prevent the rotation of the mechanism in the case of a single rack, and it is also possible to mount it as straight as possible in parallel with the three parts of the shaft. That is why. There is a disadvantage for the cautious and timid target fish because the bend 5 to the needle tip 7 are exposed, and there are cases where it is attached along the curve, but there is no rotating bait in nature. It is considered more important to prevent rotation.

Kimio Abe, Junnosuke Hayakawa, and adults of Maki Tsuji “Fishing Mechanism”, Nishitosha, published on March 15, 2000 P195 "Ship fishing" written by Katsuo Sone, Atsushi Kohinata and Atsushi Odagiri, published on May 1, 1990

Another way to attach krill to the device is to increase the appeal by showing the bait large, and tying in FIG. 7, back to back in FIG. As described above, there is a case where the krill is additionally attached to the resin Harris 16 or the like crafted with a notch jointly bound to the joint portion, but the details are omitted because there is no great relation in the present invention.

Most of the fishing hooks that use krill as a fishing bait are available on the market, and most of them have one place. There can be many reasons for this.
I. Since krill is soft and easy to slip, even if two identical fishing hooks are stacked, if there are multiple needle tips 7, the body and outer shell will tear and cannot be attached. In addition, since the plurality of needle tips 7 increase the resistance to insertion of fish into the oral cavity, the hook becomes worse.
B. Even if the shaft 3 is integral, a so-called squid type fishing hook having two or three places of the futokoro 8 is physically impossible to pierce the krill or sew the shaft 3 over the curved portion. Only the so-called “Chong” can be attached. Since the shaft 3 is visible as a fish, fish with good eyes and timid fish are not accessible.
(Basically, these fishhooks are used for aggressive large fish, squid, salmon, etc.)
C. Even with squid-shaped fishhooks, there are a number of Futokoro 8 for kneaded bait (dumpling bait), etc., which is an advantage in terms of food retention, but there are few fish species that can be caught with kneaded bait.
D. In the example of an expanding fishhook, in addition to A, B, C, the cost is very high, the strength (in terms of material stress), and the structure and configuration that cannot be achieved with the current general materials.
Etc.

As a general method for improving hooking of a fishhook, as shown in FIG. 11, the phase is changed by inserting a so-called twisting or twisting between the tip 3 and the tip 7 as shown in FIG. That is, the thickness of the flat surface itself including the roller 8 or the curved portion increases, and the needle tip 7 protrudes from one side of the flat surface. The angle of the fin is about 5 to 20 degrees. As a prior art document, there is an example in which the above-mentioned patent document includes the sash in the following patent document. However, hooks with fins trigger the above-mentioned gimmicks and bait rotation when the tide is early, when pulling the mechanism back, and at the time of collecting, so avoid the fishermen and recreational fishers who dislike it. However, the spread has remained limited. Moreover, in the region where the diameter of the shaft 3 is thin, there are many people who work on-site by twisting with a tool such as pliers and at a desired angle as necessary.

In fishing hooks / devices that use krill as fishing bait, the next factor of being eaten away by bait is bait misalignment at the time of insertion (particularly at the time of long throwing / deep seawater), and the position away from Futokoro 8 and needle tip 7 When the bait is shifted to the end, it is possible to easily eat and escape without catching the needle by holding the end and pulling it. This is because the feedability of the bait is poor and the krill cannot pass through the connecting portion 15 or the ear 2 of the fishing line 10 or the improvement of the retention at the shaft 3 or the like is insufficient. The fishing hooks and devices specified in the claims, especially in the krill bait retention, are not found in the prior art, but the Futokoro 8 is a single fishing hook, and it is a fishing hook that seems to have a significant krill retention. Are the following patent documents.

These seem to be high in bait-stopping performance, but their production is likely to be difficult, and cost performance issues must be cleared.

In order to improve the catch, it is described in the following non-patent literature that it is advantageous to put the device smoothly into the mouth of the fish on the water flow generated when the fish feeds. .

As mentioned above, Chapter VI Why fish eat food? P241 Common suction activities

There are fishing hooks and gimmicks that place importance on this element in the following patent documents, and it is important to use the water flow of suction, and the same cost problem as described above must be cleared. However, this may be a countermeasure including improvement of the mechanism and bait attachment method.

The Futokoro 8 is a single fishhook, and the most problematic part in terms of strength (stress) is the waist bend 4 and the next is the bend 5, which is a so-called curved portion. The structure for improving the strength of the curved portion is prominent in the following patent document, and it is important to consider in order to prevent the elongation and breakage and ensure the catch.

Examples of how fish eat food are detailed in the following literature:

As mentioned above, Chapter VI Why fish eat food? P236-241

This classification is roughly as follows.
Fish with slow discharge behavior
A. Pursuit type ... bonito, tuna, marlin, black bass, etc. Beggar type: yellowtail, mackerel, horse mackerel, etc. E. Chewing type ... Fish with sensitive discharge behavior such as sea bream (front-end type)
C. Suction type: Carp, Mabuna, Yamabe, Herabuna, etc. Slow eating type ... Medina (standard Japanese name, gray in Kansai), black sea bream, etc. Hit and away type ... Yamame, trout, etc.

The invention of the present application is to solve the problem of fishing hooks, gimmicks, and methods of use that can prevent feeding and escape of bait in the fishing of sea fish using krill as a fishing bait. It is a medina and black sea bream. Although it depends on the structure, shape, and dimensions, it is considered that other fish can basically be used as long as it is a fishing hook, device, and method of use that can prevent the D-type close-up fish from eating away.

The following is a summary of the issues related to eating and evacuating krill baits.
(1) To improve the hook (any means).
(2) The structure prevents the food from shifting or dropping off.
▲ 3 ▼ Good sucking in the device with bait.
(4) Do not cause strength problems.
(5) Do not cause significant cost increase.
(6) If possible, the conventional fishing hook can be modified (cost reduction means).
▲ 7 ▼ There are other benefits if possible.
Among these, (1) and (2) are essential, and (3)-(7) are optional.
The above is the issue (purpose of development).

In order to confirm the posture of the device at the time of inhalation and feeding, a simple test device having a cross section as shown in FIG. 12 was manufactured and tested. A transparent observation window (not shown) is provided on the side surface. The discharge valve 100 (ball valve) is closed, the introduction valve 101 (ball valve) is opened, tap water is filled in the polytank 110 until the seventh to eighth minutes, and then closed. When a fishing hook (device) tied with a fishing line 10a is hung just before the transparent discharge pipe 102 and a discharge valve 100 is opened to generate a water flow, the fishing hook is a needle as described in Non-Patent Document 1 below. If the tip 7 is sucked into the discharge pipe 102 and the length of the fishing line 10a is appropriate, the needle tip 7 contacts the inner wall ceiling of the pipe, as shown in FIG. In this state, if the tension of the fishing line 10 due to the suction flow is sensed with a delicate hook or the like and the fishing line is rapidly pulled up, the hook can be reliably hooked. For this reason, when fishing the C-type suction-type herabuna, etc., explained in the previous paragraph at lakes and freshwater management fishing grounds, the sensitivity and the ability to observe and judge the condition of the ground are decisive.

The above-mentioned chapter II The science of fishing equipment Fluid dynamics of fishing rod P69-P71

Next, when the fishing line 10a is fed a little and a device is inserted into the discharge pipe 102, the fishing hook lies sideways as shown in FIG. Laying down is a dynamic phenomenon that is necessary to achieve the most stable state (posture). If you can detect this state with a sensitive uki, etc. and put it together (when you pull up the fishing line 10 abruptly), it will be hooked, but it is normal that there are waves that make observation difficult in the sea, so the krill of the bait Even if it is swallowed and the contents are sucked out, it is often unclear. If you become a master of fishing, you can see what kind of events are inhaled or fed, so this state is shown and explained in the field, but it is often a subtle behavior that you can not understand even if shown.

As shown in FIG. 15, the teleost fish that is the object of fishing has an upper jaw 66 and a lower jaw 77 as the structure of its mouth, and hooking a fishhook on the hinge 88 (commonly known as “jigok”) of the joint prevents the mouth from breaking. It is the most convenient to deal with tightening (fish pulling). This is because the fish body tends to be inclined at the time of tightening, the force is dispersed, and it is easy to catch the fish because it cannot hang all the power on the fishing line 10, and the fishing line 10a is suddenly removed from the lying state of FIG. When pulled, it is convenient because the fishing hook does not stand up completely even though the shaft 3 is on the leading side, and it is easy to stick into the upper side of Jigoku. However, if you cannot read the behavior that corresponds to the subtle fish belief, you will not be able to fish because you will not perform the matching operation itself. Therefore, the reason that fishing is different in so-called fishing is that the sensitivity, observation ability, and response behavior of human beings are very different.

Also, since fish are not pumps, once the intake of food and devices has been completed and the meal has been entered, the water flow becomes loose or stops. Therefore, if the fishhook is sucked without being caught in the state of FIG. 13, it must be considered that it is normal for the fishhook to fall sideways in the oral cavity 99. Fish that feed while moving are easy to catch, but it is surmised that the D-type medina (slow-feeding type), which stops and carefully feeds, is difficult to fish, because it is presumably taken in a sideways state where it is sucked skillfully and the fishhook is hard to stick. The

In order to simulate the spout behavior, by closing the discharge valve 100 and opening the introduction valve 101 at the same time, a water flow is caused to flow backward from the discharge pipe 102 to the tank side. The fishhook was discharged on the water stream in almost the same posture as shown in FIG. 16 without causing pitching or rolling. The water pressure used is about 0.2 to 0.3 MPa for use of tap water.

Now that the behavior of the fishhook / device has been determined, linear discharge is prevented as shown in FIG. A spear fishing experiment was carried out using two sea bream using two discharge prevention barbs 43 (both sides) for harm. These two, like the tip 7 of the fin with hook, function as a protrusion from a plane including the ft roller 8. For convenience of explanation, the illustration of krill is omitted in the figure. The angle of the discharge prevention barbs 43 with respect to the main trunk of the fishhook cannot be made very large due to the installation of the krill, and the crossing angle with the shaft 3 is 10 degrees to 40 degrees. However, at a significant rate, the medina ate and ran away cleanly, and many of the other fish did not discharge well and stuck to each other.

The fish oral cavity is not as simple as the discharge pipe 12, and a support point can be formed by contact of the tip of the discharge prevention barb 43 with the oral cavity. Since there is only one, if it is pitched in the direction of the arc of FIG. 18, the needle tip 7 can be discharged without touching the oral cavity side wall. When a fish was caught, it could be inferred that the rotation in this direction was not successful, and the needle tip 7 was rotating in the direction to stab. The solid line in the figure is the lower jaw 77 side, and the broken line is the upper jaw 66 side. Accordingly, the discharge prevention barbs 54 in a direction in which the rotation of the needle tip 7 in the direction in which the needle tip 7 does not stick and the krill can be attached are directed from the forward bend 5 to the substantially lower bend 4 as shown in FIG. Two (both sides) were added in the direction of increasing the thickness with respect to the plane including the Futokoro 8. FIG. 20 shows a schematic diagram seen from the bottom view of the fishing hook as seen from inside the mouth 99 of the fish. Since the two lower discharge prevention barbs stretch, they cannot rotate in that direction as long as they are grounded. As a result of the experiment, Medina couldn't easily feed the fish, and a fishfish came out of the uki and caught a needle, or a fishfish came out of the uki and left the food and ejected it. Many other fish could not be discharged and stuck to each other.

For confirmation, without the discharge prevention barbs 43, as shown in FIG. 21, when only the discharge prevention barbs 54 were provided and the experiment was carried out, a considerable percentage of the medina ate and escaped the krill, Most of the fish caught the needle in the opposite direction without being able to discharge. This is the same as the case of only the discharge prevention barbs 43, and can be rotated in the direction of the arc of the arc in FIG. 21, so that the needle tip 7 is rotated at a position where it does not hit the inner wall in the oral cavity. It is considered to be discharged.

When both the discharge prevention barbs 43 and the discharge prevention barbs 54 are present, the reason why the effectiveness of prevention of eating and escaping is high is as follows. It is considered that a fixed line indicated by a thick alternate long and short dash line is created by these two points, and it is easy to prevent pitching rotation and linear discharge of the fishhook, and the discharge difficulty is remarkably improved.

Although these two anti-ejection barbs are allowed to rotate counterclockwise as shown in FIG. 23 around the center of gravity within the fishing hook of the fishing hook, they can prevent clockwise rotation. In this case, the counterclockwise rotation is the same as the direction when the needle tip 7 is about to be stuck in the oral cavity.

As described above, when the fishing line 10 is pulled at the time of hooking, the shaft 3 becomes the leading side, and the fishing hook tries to hook on the lip in the posture of FIG. 13, but as shown in the partial sectional view of FIG. The barbs are in a position that does not interfere with the needle tip 7 sticking into the upper lip 666.

If both the discharge prevention barbs 43 and the discharge prevention barbs 54 are present, a clear fish letter will appear on the ground even if the needle is hooked or not hooked. It is thought that it would wake up and try to escape while descending while discharging. Since the fish behaves (swims) with the device in the mouth, the rate of hooking over is improved, or the fish letter is clearly visible on the ground or fishing rod, making it easy to put together.

Therefore, the discharge prevention barbs 43 and the discharge prevention barbs 54 of the invention of the present application change the behavior of many fishes after feeding, either alone or in combination, by interfering with discharge, It is thought that the current so-called fishing hook has been changed to a fishing hook.

However, even if the angle, extension length, sharpness of the tip, attachment site, etc. of the discharge prevention barbs 43 and 54 are tested, the needle hook rate of the medina is not greatly improved (including sea conditions and ground). The device's sensitivity and the inventor's arm are also involved), so when the meringa's oral cavity, which is the target site, is cleaved and examined, as shown in FIG. 25, a very hard part on the inner wall of the front half of the oral cavity 99 As shown in FIG. 26, it can be inferred that the discharge prevention barbs 43 and the discharge prevention barbs 54 may slip without being digged in at that portion, and the discharge obstruction may not be successful.

Based on the above results, in order to further improve the needle catching rate, a krill attachment method that improves the sucking ability is adopted, so that the device is sucked deeper into the oral cavity 99, and the effectiveness of the discharge prevention barbs (disturbance of discharge) It is necessary to improve the property. 27 and FIG. 1 show an example in which a knurled connecting portion 30 that enables krill series mounting and a fishing hook with a normal ear 2 in the related (patent) document 1 and the related (patent) document are combined.

Since the present invention does not focus on krill penetration, the structure of the ear 2 and the nearby shaft 3 part is not specified in the present invention. do not do. There are four points regarding threading, and the shaft 3 is provided with a portion that joins the fishing line 10 without turning around (the coupling annular portion 30 in each figure), and the end of the fishing line 10 does not turn in the four directions, and krill In order to avoid a sudden increase in the cross-sectional area of the passing portion, the connecting portion 15 is to tie the fishing line 10 in parallel with the shaft 3 basically. Also, from the analysis of the posture control mechanism at the time of hooking, the unique feature is that the function of supporting the posture of the fishhook using the force of the fishing line 10 at the moment of hooking is maintained as it is. is there.

However, regarding the attachment of the krill, including the case where the attachment is not in series, the unique elements of the discharge prevention barbs 43 are large, so they are specified in the related terms in the claims of the present application.

FIG. 28 shows an example of krill attachment when a structure based on this related patent document is adopted. Since both ears 2 and joints 15 can be covered with krill 25, there is an effect that even cautious and timid medina can inadvertently eat, and by attaching more than one in series (no upper limit on quantity), it is easy to ride the inhaled water flow. As in 29, in the state where the fishing line 10 side of the bait is in the lips 666 and 777, the main body of the fishing hook easily enters the back of the oral cavity 99. It also meets the principles of large feeding required to catch large fish, as described in the previous paragraph. Therefore, if the discharge prevention barb group obtains a support point in the oral cavity 99, even a medina cannot be easily discharged. As a result of the experiment, Medina's fish credibility became clearer, and the probability of catching in the opposite direction / front side became very high. As shown in FIG. 30, the position where the fishhook is hung is often slightly above the hinge 88. For other fish, if the size of the oral cavity and the size of the fishhook are not in the proper range, they will be able to catch almost the other side, and as long as it is a fish that eats krill, it will almost disappear if there is no catch. Met. This makes it possible to produce fishhooks that can cope with medina and improve the hook by changing the fish behavior itself by effectively interfering with the fish ejection behavior.

Unlike other sea fishing baits (insect bait, bait, etc.), krill is soft and fragile, including the outer shell, so it is easy and easy to drop off when the fish catches and rampages. ) Also has no problem at all. This is a characteristic of only krill and amy (sasami etc.) other than kneaded bait.

A special krill attachment method related to the discharge prevention barbs 43 in the present invention will be described. After passing the krill 25 over the ear 2 side beyond the discharge prevention barbs 43, when the krill is bent back and slightly pulled back to the 4 side, the size of the krill outer shell and the span between the tips of the discharge prevention barbs 43 are appropriate. If present, as shown in FIG. 31, the tip breaks the outer shell 20p of the krill 25 from the inside, and a part protrudes. In this way, the krill retention is improved, and at the same time, the discharge blocking function of the discharge prevention barbs 43 is not disturbed by the krill outer shell 20p. The same applies to the case where only the 20 k part of the krill abdominal node is used. Even if it does not do so far for other fish, it is a phagocytic, so after eating krill in the oral cavity 99, it tries to discharge it, but Medina is a particularly timid and cautious fish that is good at feeding. This is because, when an abnormality is felt, it is discharged immediately, and as described in the previous experimental paragraph, the krill bait is often forcibly discharged. This attachment method has unparalleled performance with respect to krill retention, and is know-how from the results of experiments, but is not related to the type of discharge prevention barbs 54 of claim 3 alone.

With respect to the discharge prevention barb 54, as shown in FIG. 32, the tip is exposed after the krill is pierced. This is because the krill is attached straight to the shaft 3 to prevent rotation, but when fishing in the long throw or in the deep sea, the krill will bend and drop off in the five directions. Also, the discharge prevention barbs 54 are surely prevented. If this attachment method is observed, the discharge prevention barbs 54 are always exposed at the time of use. Therefore, there is no case where the tip is buried in the krill and does not function, which is possible in the case of the discharge prevention barbs 43.

FIG. 33 shows a kneaded state as seen from the needle tip 7 side, and FIG. 34 shows a hatching diagram showing the cross-sectional area thereof. Since the discharge prevention barbs 43 expand the width of the krill at that portion, the projected area viewed from the needle tip 7 side is increased, and the suction property is improved. In addition, it can be seen that the discharge prevention barbs 54 are exposed to have the same effect, and the suction performance is clearly improved by the matching effect as compared with the conventional fishing hook to which the same krill is attached.

As for the attachment position of the discharge prevention barb 54, as shown in FIG. 35, the rising portion where the width is widened is easier to pass krill on the side of the hip curve 4 than the curved center of the curve 5. This is because the curvature near the central portion of the curve of the bend 5 is the smallest and is the most resistant part to pierce the krill, so that when it overlaps with the rise of the discharge prevention barb 54, the krill is difficult to pass and easily collapses. It is to become. Other details will be described in the embodiment.

Examples of the side barb by moving the jaw 6 to the side surface where the jaw 6 on the curve is provided include the following patent documents. However, since the position and purpose are different, it is not useful for preventing discharge. In this position, in order to effectively prevent the clockwise rotation of the fishhook, it is conceivable to provide barbs as shown in FIG. 36, but this direction obstructs the piercing and feeding of the needle tip 7. Since counterclockwise rotation can be prevented in the same direction as the side barb, even if the discharge prevention function is fulfilled, if the protrusion height is increased so as to effectively obstruct discharge, the penetrating performance itself decreases and the hook deteriorates I think that. Furthermore, the direction of the protrusion is bad even when sucking in, and it is easy to get in the way. For this reason, it was not possible to install between the bend 5 and the needle tip 7.

Already mentioned

When the discharge prevention barbs 43 and the discharge prevention barbs 54 are attached as separate materials, it is the same as attaching a reinforcing material that increases the rigidity at the position where the force is concentrated when the fish is hooked, so it can contribute to the improvement of the strength and cause problems in the joining process. Otherwise, there will be no strength problems in the finished product. Patent documents that improve the strength of this portion mainly include the following.

Already mentioned Already mentioned Already mentioned Already mentioned

As a phenomenon confirmed in the course of the experiment, it is noteworthy that fish soaring due to cuts of mouth, the so-called ballast has been reduced. Usually, a lip with a weak mouth often breaks the lip, but it is difficult to discharge, so it is difficult to discharge. This is considered to be a factor. In order to fulfill the same function, there are the following patent documents in which the cross-sectional shape of the bending portion is devised.

The effects of the invention are summarized as follows.
For issue (1)
By providing the discharge prevention barbs 43 and / or the discharge prevention barbs 54, it is possible to improve the hook by changing the fish's behavior by interfering with the discharge of the mechanism, and in many cases the fish can be caught in the opposite direction. That made fishing easy and secure.
For issue (2)
By providing the discharge prevention barbs 43 and / or the discharge prevention barbs 54, the function of preventing the displacement and dropping of krill has been remarkably enhanced.
For issue (3),
By providing the discharge prevention barbs 43 and / or the discharge prevention barbs 54, the projected area with the krill attached is increased, and the suction performance on the water flow when the fish feeds is improved.
For issue (4),
By providing the discharge prevention barbs 43 and / or the discharge prevention barbs 54, it is possible to improve the strength of the curved portion (between the hip bend 4 and the forward bend 5) and to prevent elongation and breakage. It became like.
In response to issue (7) As another effect, fish dropout (so-called balashi) has been significantly reduced.
Issues (5) and (6) will be described in the embodiments.

For the production of the fishhook main body, the parts without special elements are omitted, and the basic parts mainly related to the discharge prevention barbs 43 and the discharge prevention barbs 54 and their cautions will be described in detail.

A region where the discharge prevention barbs 43 and the discharge prevention barbs 54 should not partially penetrate will be described.

As for the discharge prevention barb 54, when the state in which the needle tip 7 is set to the right is written as a front view, the hatched area in FIG. It is better not to. One guideline for the height (upward) direction of the non-intrusion area 200 from the curved portion is the position of the jaw 6, and it may be determined at a position where the designer determines that the jaw 6 is sufficiently pierced to a depth at which the function is achieved. If the position of the jaw 6 is set to the upper position or the position of the out-barb is moved to the upper position, the tip position of the discharge preventing barb 54 is slightly raised. On the other hand, the side opposite to the bottom roller 8 (the lower side of the bend 5-the lower side of the bend 4 in the figure) can enter as long as the krill permeability is not hindered.

The non-intrusion region 300 for the discharge prevention barb 43 is a portion corresponding to the upper lip 666 of the fish as viewed from above, as shown in FIG. It must be avoided because it interferes with the hook. If it can be controlled in production, it is preferable that the fishhook does not enter at all on the side of the hook roller 8. On the contrary, the area opposite to the bottom roller 8 (the left side of the shaft 3 in FIG. 37) can enter as long as the krill permeability is not hindered.

By protecting the above two points, it is possible to achieve the installation of discharge prevention barbs that do not impair the hooking function of the fishing hook.

Next, the crossing angle T of the discharge prevention barbs 43 and the discharge prevention barbs 54 with respect to the fishhook main body (main trunk) (not including build-up such as soldering and brazing) is a bottom view of FIG. 39 and a left side view of FIG. As shown in the figure, the overall condition is about 10 to 40 degrees, and it is a condition that the krill permeability can be secured. When the whole is curved, it is sufficient to consider the tangential direction of the curve. The tip (terminal / pointed side) may be parallel to the main trunk as long as the non-intrusion regions 200 and 300 and the krill are satisfied without satisfying this condition. It is defined as having the previous angle. The angle T and the degree of curvature may be designed by determining the approximate range of krill to be used, depending on the size of the fishhook body, the target fish, and the like. In the embodiment of FIG. 39, the apex side of the discharge prevention barbs 43 and the discharge prevention barbs 54 are curved and the angle at the rising portion side is shallow. In the embodiment of FIG. Therefore, it will be easy to pass through the krill. In order to suppress the total width, in the embodiment of FIG. 40, the rising portion has the above-mentioned angle, and the angle is made parallel to the minus side or shallow to the minus side by curving only the tip side. In the case of mounting by joining, it is possible to install without brazing by brazing and welding at the contact surface (interface), but in that case, the side where krill is inserted so as not to impede penetration It is necessary to improve the contact at the corners.

As for the protruding height from the main trunk to the tip, we want the minimum main trunk thickness on one side for the tested megina, so as shown in FIG. 41, set the pitch between the discharge prevention barbs (54, 43) on both sides as a pair. The total protrusion amount S is required to be about three times or more of the main trunk. In particular, there are fish that do not need to be large in length or height, so it is only necessary to determine the overall size of the fishhook, the target fish, and the recommended krill size.

In summary, the penetrability is inversely proportional to the intersection angle T, and the total protrusion amount S is proportional to the intersection angle T. The size of each part of the fishhook is related to the limiting condition, and when the crossing angle T is reduced, a length is required to obtain the required total protrusion amount S. Therefore, it is necessary to decide in consideration of merits and demerits and fish species. As a result of the experiment, the crossing angle T needs to be larger for fish that are hard in the oral cavity 99 or fish that are better discharged.

In the case of a circular cross section, the wire diameters of the discharge prevention barbs 43 and the discharge prevention barbs 54 attached by joining are tested at about 70% (half the cross-sectional area) to 50% (1/4 cross-sectional area) of the main trunk diameter. However, in the area where the thickness of the main trunk is small, it may be larger, so it is difficult to define in the claims. As long as the cross-sectional shape can be obtained by wire or formed by a press, the cross-sectional shape may be an irregular cross-section with the purpose focused on rigidity and cutting ability. As for the cross-sectional shape of the main trunk, it is preferable to flatten with a press, since it is easier to attach when the side of the curved portion has a flat portion, and can improve the strength of the roller.

With regard to the shape of the tip (tip / end) in the joined product, it is not necessary to catch the fish at this part, but the tip only has to be functionally hooked to the inner wall of the oral cavity 99 of the fish. It may be pointed, and may be a truncated cone having an acute angle of 90 degrees or less by cutting off the cone only at the tip, or a cylindrical shape with the tip cut off at an angle. It is also effective to squeeze the tip to make it flat and to provide a lot of spines such as bifurcates. As shown in FIG. 40, when the whole is sharpened in a tapered shape, it is not preferable because it is deeply inserted into the user's finger, but it is also necessary to change the individual target fish. Accordingly, it is defined that it is only necessary to have an acute angle part of 90 degrees or less at the tip part.

If the main trunk can be made sufficiently thick and there is room to include the safety factor, it is the same as molding the jaw 6 and, before the process of increasing the hardness, as shown in FIG. Is also possible. It is preferable that the bite has a curved surface rather than a flat shape so that the cross-sectional area on the spine side can be increased. In the case of the construction method similar to the jaw 6, it is difficult to form the discharge prevention barbs 43 and the discharge prevention barbs 54 that are too long, and attention is also paid to the occurrence of cracks in the quenching process.

Since the shape of the discharge prevention barbs 54 and 43 only needs to fulfill the function, it may take any form as long as it is within a specified angle or tip shape. For example, as shown in FIG. Even if left-right symmetry is not achieved, it does not matter.

In the discharge prevention barbs 43 and the discharge prevention barbs 54 attached by joining, there are basically two types of handling, and one type of application example. As shown in FIG. 44, the simplest handling is to join the crushed legs by soldering. It is preferable to perform soldering and brazing after temporarily fixing by resistance welding or the like, since the strength of peeling is improved, which is effective for the problem (5).

The handling of FIG. 45 is relatively easy to position because the way of bending the legs is opposite to that of FIG. If the legs are crushed with a press to reduce the height as much as possible, it is easy to ensure permeability.

The handling shown in FIG. 46 integrates FIG. 44 and FIG. 45 so that the discharge prevention barbs 43 and the discharge prevention barbs 54 can be handled at the same time, which is easy to manufacture and can also improve the strength of the curved portion. The overall cross-sectional area difference can be reduced. After temporarily fixing by resistance welding or the like, soldering or brazing may be performed, which is effective for the problem (5).

It is important to connect the krill insertion direction (direction from the needle tip 7 to the ear 2) smoothly in common with the above three types of joints.

In the case of a large main trunk / fishhook, as shown in FIG. 47, if the rising positions of the discharge prevention barbs on the front and back sides are shifted and attached obliquely, the krill can be easily passed.

When the product of temperature and time, such as resistance welding and soldering, is small, it is possible to attach after the entire process of the main body is completed, or to attach the discharge prevention barbs 43 and discharge prevention barbs 54 to a commercially available product, Costs can be easily reduced by reducing hardware and labor, and the problem (6) can be solved.

When joining quality is improved by using brazing, etc., quenching cannot be performed. Therefore, the main body material can be changed to a precipitation (aging) hardening alloy for springs. For age hardening, a vacuum furnace or gas atmosphere furnace is used. Etc., the oxidation may be less.

Based on the above basic part and precautions, each embodiment diagram is sorted for each claim. The figure number is described again.

Examples of a fishing hook according to claim 1 are shown in FIGS. 1, 27, 35, 37, 39, 40, 42, 43, 48, 49, 50, 51, and 52. It is.

Examples of the fishing hook according to claim 2 are FIGS. 17, 38, 53, 54, 55, 56, 57, and 58, respectively.

Examples of the fishing hook according to claim 3 are shown in FIGS. 59, 60, 61, 62, and 63.

FIG. 41 is a diagram for explaining the dimensions of the fishing hook according to the fourth aspect.

The embodiment of the device coupled with the fishing line 10 according to claims 1, 2, 3 and 4 is omitted because the so-called Harris fishing hook coupled with the normal fishing line (resin Harris) 10a is common sense and is omitted. Only listed. The one using the knitting yarn 10b as shown in FIG. 64 is used for fish that has sharp teeth on the lips and is worn by the fishing line 10a, such as chromedina (standard Japanese name, local name Ogre Gure, Wakana, etc.). The fishing line 10a is coupled to the end ring 17 for use. The portion 17a in which the end of the knitting yarn 10b is hardened with resin or the like is also a device for piercing the krill. Even those manufactured with a relatively short knitting yarn 10b have the advantage of not injuring the fingers during joining. As shown in FIG. 65, the one using the wire 10c is for a biting fish such as a sea bream or a sea bream. Since the swing joint 15 and the end ring 17 rub against a hard object, the wire is doubled as in the conventional product.

The details of the method of using the krill according to claims 1 and 2 have been described above.

As for the one sold as a fishhook alone, in order to prevent the discharge prevention barbs 43 from scratching the fishing line 10 and piercing it with fingers when combined, as shown in FIG. It is even better to put on. After making the device, remove it before attaching the krill.

When connecting the fishing hook of FIG. 1 or the like in which the connecting portion 15 and the ear 2 pass the krill, and the connecting annular portion 30 is arranged on the opposite side of the foot roller 8, it is safe to hold it as shown in FIG. is there. In the case of a right-handed person, if the index finger 600 indicated by a solid line and the thumb 700 indicated by a broken line are sandwiched flatly between the shaft 3 and the discharge prevention barbs 43 as shown in FIG. 67, the discharge prevention barbs 43 do not pierce the fingers. The fishing line 10 may be coupled with a simple knot such as a clinch knot. In a fishing hook in which the connecting annular portion 30 is arranged on the side of the bottom roller 8, it is preferable to hold it as shown in FIG. 68 with the needle tip 7 (side of the bottom roller 8) facing up.

Note that there are many cases in which the fishing hook is sold as a single unit, and there are many cases where the ejection preventing barbs are torn, and the conventional flat resin bag-like package is torn, or the ejection preventing barbs themselves are deformed. It is better to pack it in the packing material 500 that can be worn.
