Floating rig for fishing {FLOATING TYPE TACKLE FOR FISHING}

The present invention relates to a liquid rig for fishing.

As a floating rigging for fishing, for example, a sea bream rubber jig (Tai Kabra) has a weight as its head. As this weight, a substantially spherical hole weight is generally used. That is, a fishing line is slidably inserted into a through hole formed in a substantially spherical weight, and a fluid body having a fishing hook and a fishing member (tie, skirt, etc.) is connected to the distal end of the fishing line, whereby the fluid moves through the hole. It is configured to be relatively movable with respect to weight.

In addition, in the hole weight, in order to prevent the fishing line inserted through the through hole from being damaged by contact with the inner circumferential surface of the through hole, Japanese Utility Model Registration No. 3190126 (Patent Document 1) directly inserts the fishing line into the through hole A snapper rubber jig having as a head a weight configured to protect the fishing line from damage due to contact with the inner circumferential surface of the through hole by inserting a resin tube into the through hole and passing the fishing line through the tube instead of passing through the through hole. .

Japanese Registered Utility Model Publication No. 3190126

In general, a high hooking rate of a fishing hook to a fish is required for fishing equipment. Therefore, the present inventors obtained the following knowledge as a result of research on the hooking of a fishing hook to a fish in a sea bream rubber jig.

That is, according to the conventional sea bream rubber jig, since a substantially spherical hole weight is used as a weight, in a state where the weight and the fluid are suspended from the fishing line, the fishing hook of the fluid and the fishing member are located below the weight. For this reason, the total length of the rig is increased, and while this exhibits the effect of enhancing the fish-fishing action, it has caused a decrease in the hooking rate of the fishing hook to the fish. In addition, in order to suppress interference between the fishing hook and the fishing member, it is necessary to lengthen the fishing member, and this also causes the total length of the rig to increase, resulting in a decrease in the hooking rate.

The present invention has been made based on the above findings, and its object is to provide a liquid rig for fishing with a high hooking rate to fish.

The present invention provides the following means.

1) A floating rig for fishing comprising a weight having a fishing line insertion hole and a fluid having a fishing hook, and the fluid being connected to the tip of a fishing line slidably inserted into the fishing line insertion hole,

The weight is of a shape extending in the vertical direction, and the fishing line insertion hole is formed at the upper end of the weight,

In a state in which the weight and the fluid are suspended from the fishing line, the fishing hook is located on the lateral side of the weight.

2) The weight is formed separately from the weight body extending in the vertical direction, the weight body and the connection hole for connecting the weight body to the fishing line, and the connection that detachably connects the weight body and the connection hole Along with providing the means,

The floating rig for fishing according to the preceding paragraph 1, wherein the fishing line insertion hole is formed in the connection port.

3) The connecting means includes an eye, a hook that is lockable to and detachable from the eye, and a closing member that closes the opening of the hook,

One of the eye and the hook is installed at the upper end of the weight body, and the other is installed at the connection hole,

By locking the hook to the eye, the weight body and the connector are connected, and

The liquid rig for fishing according to the preceding paragraph 2, wherein the closing member is configured to be movable between a closed position for closing the opening of the hook and an open position for opening the opening of the hook in a state in which the hook is locked to the eye.

4) the connecting means includes a first eye, a second eye, and a split ring for detachably connecting the first eye and the second eye;

The first eye is installed on the upper end of the weight body, and the second eye is installed on the connector,

6) The floating fishing rig according to the preceding paragraph 5, wherein the fishing hook is located on the lateral side of the constricted portion of the weight in a state in which the weight and the fluid are suspended from the fishing line.

The present invention has the following effects.

In the foregoing claim 1, when the weight is a thing of a shape extended in the vertical direction, the fish trapping action is increased. Then, the fishing line is slidably inserted into the fishing line insertion hole formed at the upper end of the weight, and the fishing hook is positioned on the side of the weight in a state where the weight and the fluid are suspended from the fishing line, thereby reducing the fishing hook to the fish You can increase the hooking rate.

In the preceding paragraph 2, since the connecting means for detachably connecting the additional weight body and the connection port is provided, the weight body and the connection port can be separated when replacing the weight body. Therefore, the weight body can be replaced with another weight body without cutting the fishing line.

In the preceding paragraph 3, since the closing member of the connecting means is configured to be movable between a closed position for closing the opening of the hook and an open position for opening the opening of the hook in a state in which the hook is locked to the eye, the exchange operation of the weight body is facilitated. can do

That is, when the weight body is separated from the fishing line, if the opening of the hook is opened by moving the closing member from the closed position to the open position, the hook can be unlocked from the eye and the weight body can be separated from the fishing line. And, when attaching a separate weight body to the fishing line, locking the hook to the eye with respect to the separate weight body and closing the opening of the hook with the closing member by moving the closing member from the open position to the closed position, the separate Since the weight body can be attached to the fishing line, the locking state of the hook to the eye can be maintained so that the hook is not unintentionally unlocked from the eye. Therefore, the work of exchanging the weight body can be easily performed.

In the preceding item 4, since the connecting means is provided with a split ring that connects the first eye and the second eye in a detachable manner, the work of exchanging the weight body can be easily performed.

That is, when separating the weight body from the fishing line, the weight body can be separated from the fishing line by separating the first eye from the split ring. And, when attaching another weight main body to a fishing line, the said another weight main body can be attached to a fishing line by connecting the 1st eye of another weight main body to a split ring. Therefore, the work of exchanging the weight body can be easily performed.

In the preceding paragraph 5, since the weight is formed in a substantially rotating body shape centered on its axis, the sinking speed (fall speed) of the weight in the water can be increased compared to the case where the weight has a substantially long plate shape.

In addition, since the constriction portion is formed along the entire circumference of the weight in an approximately intermediate portion in the vertical direction of the circumferential surface of the weight, rotation of the weight during submergence in water is suppressed. This can reduce the entanglement of the fishing hook at the time of submersion of the pendulum.

In the preceding clause 6, it is easier for the hook to hook onto the fish, and the hooking rate of the hook to the fish can be further improved.

In this first embodiment, the connector 11 corresponds to the body Y with the eye 13 attached, and the weight body 2 corresponds to the main body X with the hook 3 attached.

As shown in FIG. 5, the closing member 21 of the connecting means 20 is formed of a resin molded body having a substantially disc shape or a substantially single column shape. As shown in FIGS. 5(c) and (d), a cross-section substantially cross-shaped slide hole 22 is formed in the central portion of the closing member 21 in the vertical direction (thickness direction) of the closing member 21.

And, as shown in FIG. 6, the closing member 21 closes the opening 3a of the hook 3 in the state where the hook 3 is locked to the eye 13, and as shown in FIG. 7 Similarly, the weight body 2 (body X with hook 3 attached) and connector 11 (body with eye 13 attached) in the open position where the opening 3a of hook 3 is opened (Y )), the eye 13 and the hook 3 are inserted through the slide hole 22 of the closing member 21 in a press fit state and slidably so as to be able to slide between them.

That is, the slide hole 22 has a substantially cross-shaped cross section as described above, and in detail, the first hole portion 22a having an approximately I-shaped cross section through which the eye 13 passes, and the first hole portion 22a ), and is constituted by a substantially I-shaped second hole portion 22b in cross section through which the hook 3 passes.

In the state in which the closing member 21 is disposed in the closed position (FIG. 6), the hook 3 of the eye 13 and the hook 3 is pressed into the second hole 22b of the slide hole 22 and also It is inserted so that it can slide. Also, in this state, the closing member 21 (in detail, the lower surface 21b of the closing member 21) collides with the upper end of the weight body 2 (the body X to which the hook 3 is attached) .

In the state where the closing member 21 is disposed in the open position (FIG. 7), the eye 13 is inserted into the first hole portion 22a of the slide hole 22 in a press-fitting state and slidably. Further, in this state, the closing member 21 (more specifically, the upper surface 21a of the closing member 21) collides with the lower surface of the coupler 11 (main body Y to which the eye 13 is attached).

In Figs. 6 and 7, the fishing line 50 (see Fig. 4) passed through the fishing line insertion hole 12 is not shown.

In addition, as shown in FIG. 5, the surface of the closing member 21 facing the side of the weight body 2 (main body X to which the hook 3 is attached), that is, the lower surface 21b of the closing member 21 is A groove portion 24 extending along the second hole portion 22b of the slide hole 22 in the radial direction of the lower surface 21b is formed. As shown in Fig. 5(b), the groove portion 24 has a substantially inverted U-shaped cross section that opens downward, and as shown in Fig. 7, the hook 3 ) functions as a passage through which the hook 3 passes when locking to the eye 13 and when locking of the hook 3 from the eye 13 is released.

However, as shown in FIG. 1, the hook 3 of the weight body 2 is locked in the eye 13 of the coupler 11 through which the fishing line 50 is inserted into the fishing line insertion hole 12, and the fishing rod ( In a state where the weight 1 and the fluid 40 are suspended from the fishing line 50 (not shown), the weight body 2 of the weight 1 is located lower than the connector 11 due to its own weight and is free from the eye 13 As shown in FIG. 6, the closing member 21 is placed in the closed position so that the opening 3a of the hook 3 is closed with the closing member 21. At this time, the closing member 21 collides with the upper end of the weight body 2 (body X to which the hook 3 is attached).

In this state, as shown in FIG. 1, the fishing hook 45 is located on the lateral side of the weight body 2 (weight 1), and in detail, the lateral side of the contraction portion 2a of the weight body 2 All fishing hooks 45 are located nearby.

The gear 60 is used for fishing in the above state.

In the case of replacing the weight body 2 with another weight body in this rigging 60, as shown in Fig. 6, when the closing member 21 is slid from the closed position to the open position with a fingertip (not shown). As shown in FIG. 7, the opening 3a of the hook 3 is opened, and the closing member 21 collides with the lower end of the connection port 11 (main body Y to which the eye 13 is attached) and the closing member The movement of (21) is stopped. Therefore, the closing member 21 can be reliably placed in the open position. Further, in this state, the closing member 21 moves downward (that is, to the closed position side) by the frictional force between the slide hole 22 (the first hole portion 22a of the slide hole 22 when explained in detail) and the eye 13. ) is held in the open position to prevent accidental movement.

Next, the hook 3 of the weight body 2 is unlocked from the eye 13 of the coupler 11. At this time, the hook 3 passes through the groove 24 in the unlocking direction from the eye 13 of the hook 3. As a result, the weight body 2 is separated from the fishing line 50 (connection port 11).

Then, with the closing member 21 disposed in the open position, the hook 3 of the separate weight body is locked to the eye 13 of the connector 11. At this time, the hook 3 passes through the groove 24 in the locking direction of the eye 13 of the hook 3. Then, when the closing member 21 is slid from the open position to the closed position with the fingertip, as shown in FIG. 6, the opening 3a of the hook 3 is closed with the closing member 21, and the closing member 21 ) collides with the upper end of the weight body 2 (body X to which the hook 3 is attached), and the movement of the closing member 21 is stopped. Therefore, the closing member 21 can be reliably placed in the closed position. In addition, the closing member 21 moves upward (that is, to the open position side) due to the frictional force between the slide hole 22 (the second hole portion 22b of the slide hole 22, if explained in detail) and the hook 3. It is held in the closed position so that it does not move unintentionally.

Exchange work of the weight body 2 is performed in the above procedure.

According to the rigging 60 of the first embodiment, since the weight main body 2 of the weight 1 has a shape extending in the vertical direction, a high fishing effect can be exhibited. In addition, as shown in FIG. 1, in the state where the weight 1 and the fluid 40 are suspended on the fishing line 50, the fishing hook 45 is located on the side of the weight body 2, not the lower side of the weight body 2, Because of this, the overall length of the rig 60 can be shortened, and the hooking rate of the hook 45 to the fish can be improved.

In addition, the fishing hook 45 is located on the lateral side of the constricted portion 2a of the pendulum body 2, so that the hooking rate can be further improved.

In addition, since the weight body 2 is formed in a substantially rotating body shape centered on its axis, the sinking speed (fall speed) of the weight body 2 in water is higher than when the weight body 2 is substantially long plate shape ) can be increased.

In addition, since the constriction portion 2a is formed at approximately the middle portion of the circumferential surface of the weight body 2 in the vertical direction, rotation of the weight body 2 during sinking in water is suppressed. Therefore, it is possible to reduce entanglement of the fishing hook 45 or the necktie 43 (picking member 42) when the pendulum main body 2 sinks in the water.

In addition, a plurality of protrusions 2b for rectification are formed at equal intervals in the circumferential direction of the lower portion at a lower portion of the constriction portion 2a on the circumferential surface of the weight body 2, so that the fishing line 50 The rotation of the weight body 2 in water at the time of winding up of ) is suppressed. Therefore, it is possible to reduce entanglement of the fishing hook 45 or the necktie 43 (picking member 42) even at the time of winding up.

Here, the lower limit of the length of the weight body 2 is not limited, but in order to reliably exhibit the above-mentioned effect, the length of the weight body 2 is at least twice the maximum diameter of the weight body 2. desirable. The upper limit of the length of the weight body 2 is not limited either, and is usually 5 times or less of the maximum diameter of the weight body 2.

Further, according to the rigging 60 of the first embodiment, since the fishing line 50 does not need to be cut when replacing the weight body 2 as described above, the replacement work of the weight body 2 can be easily performed. can

In addition, on the lower surface 21b of the closing member 21, as a passage through which the hook 3 passes when locking the hook 3 to the eye 13 and releasing the lock from the eye 13 of the hook 3 Since the groove portion 24 is formed, the length of the movement stroke of the closing member 21 moving between the closed position and the open position can be shortened as much as possible, whereby the movement operation of the closing member 21 can be easily performed. .

In addition, since the hook 3 is installed in the weight body 2 and the eye 13 is installed in the connector 11, the closed position is located lower than the open position, and the closed position disposed in the closed position Gravity is acting downward on the member 21 . Therefore, it is possible to prevent the closing member 21 from accidentally moving from the closed position to the open position, whereby the closing member 21 can be securely held in the closed position.

Here, in the first embodiment, the hook 3 is provided in the weight body 2 and the eye 13 is provided in the joint 11, but in the present invention, the eye ( 13) may be installed, and the hook 3 may be installed in the connector 11. In the case of the latter, the weight body 2 corresponds to "the main body Y with the eye 13" and the joint 11 corresponds to the "main body X with the hook 3".

In the floating equipment 60A for fishing according to the second embodiment of the present invention shown in FIG. 8, the connecting means 20A includes the first eye 5, the second eye 13, the first eye 5 and A split ring 28 connecting the second eye 13 detachably is provided.

The first eye 5 has a substantially semi-circular shape to a substantially inverted U-shape. And this 1st eye 5 and the eye 13 of the coupler 11 (this corresponds to the 2nd eye 13 of the connection means 20A) are connected via the split ring 28, The body 2A and the connector 11 are detachably connected to form the weight 1A.

In addition, the coupler 11 and the fluid body 40 have the same configuration as those in the first embodiment.

In the case of replacing the weight body 2A with another weight body in the rigging 60A of the second embodiment, the first eye 5 of the weight body 2A is separated from the split ring 28 so that the weight body ( 2A) is separated from the fishing line 50 (connection port 11). Subsequently, the other weight body can be attached to the fishing line 50 by connecting the first eye 5 of the other weight body to the split ring 28 . Therefore, the weight body 2A can be replaced with another weight body without cutting the fishing line 50, and thereby the replacement work of the weight body 2A can be easily performed.

Although several embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention.

For example, in the above embodiment, the tie 43 is used as the gripping member 42 of the fluid 40, but a skirt or the like may be used as the gripping member in the present invention.
