Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lure, and in particular, a fixed weight is provided with a hollow portion capable of accommodating the movable weight, so that when the lure is cast, the movable weight contained in the hollow portion of the fixed weight. By moving the moving weight to the rear of the main body and moving the moving weight from the rear into the hollow portion of the fixed weight to stop and store the weight, the moment of inertia with respect to the swing center of the main body is made extremely large during casting and the lure posture is adjusted. While stabilizing and increasing the flight distance, by focusing all weights consisting of fixed weights and moving weights near the tip at the time of swimming, the moment of inertia of the main body is reduced to make it easier to swing, and it is a crisp and crisp action. To improve the flight distance and achieve a sharp action with the conflicting functions. About the lure was to be raised a good fishing.

[0002]

2. Description of the Related Art In fishing for black bass and the like, it is common practice to use a lure made in a shape similar to a fish as a pseudo bait. As a function required for a lure to raise a good fishing result, a large flight distance and a crisp and sharp action (swing motion) similar to that of a real fish are required. As the flight distance increases, the fishing area can be expanded correspondingly, and the sharp action can improve the biting of the black bass by making it act closer to a real fish, and as a result, It can be connected to the improvement of fishing results.

In order to improve the flight distance of the lure, it is important to fly the main body in a stable posture from the tail portion. For this purpose, the weights are arranged in a dispersed manner in the longitudinal direction of the main body and shaken. It is necessary to increase the moment of inertia with respect to the center of motion. In addition, in order to achieve a sharp action, it is necessary to concentrate the weight as much as possible and reduce the moment of inertia with respect to the swing center located in the front part of the main body to facilitate swinging, improving the flight distance. The sharp action has the characteristics that conflict with each other,
It was extremely difficult to make them compatible.

The conventional lure 1 is realized in a balanced form so as to satisfy the above-mentioned contradictory characteristics to some extent. That is, in FIG. 16, two weight receiving chambers 2a are provided in the main body 2 made of synthetic resin or the like in a shape similar to a fish, and the weights 3 are stored in the weight receiving chambers 2a, respectively. Was fixed in the main body 2. Below the body 2 and the tail 2b
A fishing hook 4 is swingably connected to the fishing line 4, and one end of a fishing line 6 wound around a reel (not shown) of a fishing rod 8 is fixed to a line eye 5 fixedly provided at the front end.

By arranging the two weights 3 so as to be dispersed in the front and rear without being widely separated from each other, the moment of inertia with respect to the swing center is set to a certain degree, and the flight distance is improved and sharp. I tried to achieve a balance between the two characteristics that conflict with the action. As a result, during the casting performed by swinging the fishing rod 8 in the direction of the arrow B, the main body 2 can fly without losing its posture, and a proper flight distance can be secured.
Also, during the swim, the main body 2 was designed to obtain an action of swinging left and right. However, since the two contradictory characteristics are made compatible with each other, both the characteristics are not sufficient, and in order to further increase the fishing result, the both contradictory characteristics described above can be satisfied at the same time and completely. The lure was longing.

Further, as another conventional lure, there has been proposed one in which weights are fixed at one point in the main body and concentratedly arranged with emphasis on sharp action. The lure has a small moment of inertia with respect to the center of swing, so it is easy to swing, and it is possible to obtain a crisp action as an ideal pimple.However, since the moment of inertia is small, the body wobbles and the posture Had a drawback in that it flew in an unstable state, and as a result the flight distance could not be increased.

As a lure for solving the above problem, a fixed weight and a moving weight are provided in the main body, and the moving weight is moved to the rear of the main body during casting to increase the moment of inertia with respect to the swing center, and the moving weight is used during a swim. It has also been proposed to move the front part near the fixed weight to reduce the moment of inertia, but it is not possible to integrate the fixed weight and the moving weight and separate them in the separated state. Since it is accommodated in the place of, the moment of inertia with respect to the center of swing cannot be made sufficiently small, and there is a drawback that a satisfactory sharp action cannot be obtained.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. The purpose of the present invention is to provide a fixed weight having a hollow portion in the longitudinal direction of the main body. Along from the center to the front,
A movable weight that is movable from the front to the rear or from the rear to the front in the rolling guide portion formed toward the rear of the main body in communication with the hollow portion is provided. By moving it, the moment of inertia with respect to the swing center of the whole body is made very large so that it can fly in a stable posture, and at the time of swimmering, the moving weight is housed in the hollow part of the fixed weight and all the weights are lengthwise. By concentrating from near the center to near the tip to reduce the moment of inertia of the main body and making it easier to swing, the flight distance of the lure is increased and a sharp action extremely similar to the movement of a real real fish is performed. It is to be able to realize it at the same time, and by doing this, the fishing area can be expanded and And well-conditioned There is to be able to increase the good fishing.

Another object of the present invention is to construct a stationary weight having a hollow portion by a magnet, and a movable weight made of a magnetic material. It can be adsorbed and contained, and even if the posture of the main body changes a little due to acceleration when it hits an obstacle or the main body moves in any direction, the moving weight can be stably stopped in the hollow portion of the fixed weight. This is to ensure that a stable and crisp action is always obtained.

Still another object is to set the attraction force of the moving weight by the magnet so that it has a magnetic force smaller than the centrifugal force acting on the moving weight during casting.
When casting, the moving weight can be moved backwards by separating it from the fixed weight against the magnetic force, and this also makes the moment of inertia of the whole body about the swing center during casting very large. To stabilize the flight attitude and increase the flight distance.

Another object is to adjust the weight balance of the entire main body by adding the auxiliary weight to the moving weight and the fixed weight and fixing the auxiliary weight in the main body in front of or behind the fixed weight. It should be possible to adjust the lure so that it does not rise or sink too deep in the water.

[0012]

In summary, according to the present invention (claim 1), at least one fishing hook is attached to the main body and the fishing line connected to the tip of the fishing line is pulled to move the main body forward while moving the left and right by the action of the lip. In a lure that is made to look like a fish by swinging to a real fish so that a real fish can be caught with the fishing hook, a fixed weight having a hollow portion formed forward from the vicinity of the longitudinal center of the main body, and the fixed weight from the fixed weight A hollow rolling guide portion formed toward the rear of the main body and communicating with the hollow portion of the fixed weight, and when casting the lure, rolls from the front to the rear in the rolling guide portion to the rear of the main body. At the same time as the moving weight is moved, the moving weight is rolled in the rolling guide portion from the rear side to the front side to move into the hollow portion of the fixed weight to be stopped and accommodated. During casting of the lure, the moving weight is moved rearward to greatly increase the moment of inertia of the main body with respect to the swing center to stabilize the posture, and when the lure is swung, all weights are moved from near the longitudinal center of the main body to near the tip. It is characterized in that it is configured so as to be easily concentrated to reduce the moment of inertia of the main body so as to easily swing.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the embodiments shown in the drawings. 1 to 4, a lure 10 according to the present invention includes a fixed weight 11 and a rolling guide portion 12.
A and a moving weight 13 are provided.

In FIGS. 1, 3 and 4, the lure 10 is shown.
The main body 12 is made of synthetic resin or the like to have an outer shape resembling a fish, and the abdomen 12b and the tail 12 of the main body 12 are manufactured.
With reference to FIG. 12, one end of the fishing line 16 wound around a reel (not shown) of the fishing rod 18 is also attached to the line eye 15 fixedly provided at the front end of the fishing line 14 that is swingably connected to c. Is fixed. Further, below the line eye 15, a plate-shaped lip 12d made of synthetic resin or the like is formed so as to project forward and downward.

The fixed weight 11 is located in front of the main body 12 in FIG. 2 and is fixed in the main body 12 by means such as integrally molding with the main body 12. From the fixed weight 11 fixed inside the main body 12, a hollow rolling guide portion 12a is formed toward the rear of the main body 12,
One end of the rolling guide portion 12a communicates with the hollow portion 11a of the fixed weight 11, and the other end is closed to form a bag.

The fixed weight 11 of the first embodiment shown in FIGS. 2 and 5 to 8 is manufactured by processing a metal into a hollow hexagonal column having a hollow portion 11a having a bottom at the center.
The moving weight 13 is a ball made of metal such as steel or tungsten and has a diameter smaller than the diameter of the hollow portion 11a so that it can be easily accommodated in the hollow portion 11a. Further, the hollow portion 11a is not limited to the closed space as illustrated, but the fixed weight 11a
Alternatively, two plates (not shown) may be placed upright and arranged in parallel, and the moving weight 13 may be housed in the middle of the two plates. Furthermore, the shape of the fixed weight 11 is not limited to a hexagonal prism, and may be a polygonal prism such as a square prism or an octagonal prism, and is not limited to a columnar shape, and may be an open roof shape or a U-shape. Alternatively, it may be made bottomless and pressed against a rib or the like (not shown) of the main body 12.

The fixed weight 21 of the second embodiment shown in FIGS. 9 and 10 is a metallic hollow hexagonal column member 22 having a hollow portion 22a formed therethrough and a hexagonal plate made of a magnetic material such as a magnet. And a bottom plate 23 having a magnetic force formed into a shape, and the bottom plate 23 is fixed to one end of the hollow hexagonal column member 22 to close one end of the hollow portion 22a. The moving weight 24 is a ball made of a magnetic material such as iron, and is attracted to the bottom plate 23 by a magnetic force so that the hollow portion 22a is
It is configured to be stably contained within.

In FIG. 2, the main construction of the present invention is constructed as described above, but if necessary, the auxiliary weight 31 may be fixed to the front or rear side of the fixed weight 11 in the main body 12. It can also be provided.

The present invention is configured as described above,
The operation will be described below. In FIG. 11 and FIG. 12, casting of the lure 10 is performed by the angler 25 standing up the fishing rod 18 at the rear position shown by the phantom line in FIG. 11 and then swinging the lure 10 forward. It is carried out by dropping at the target landing point 26A. While the fishing rod 18 is being extended, the lure 10 is restricted by the fishing line 16 as shown in FIG. 12, the line eye 15 is located in front (on the side closer to the fishing rod 18), and the tail portion 12c faces rearward. Drawn out. At this time, the moving weight 13 is the hollow portion 1 of the fixed weight 11 that has been accommodated.
1a, and the rolling guide portion 12a by inertial force
It rolls from the front to the rear and is located at the tail portion 12c that is the farthest from the fixed weight 11.

When the movement of the fishing rod 18 is stopped after the swinging of the fishing rod 18 is completed, the lure 10 flies forward due to the inertial force, but the resistance generated when the fishing line 16 is paid out acts on the line eye 15 to cause the lure 10 to fly. The flight direction is reversed and the tail 12c flies forward.

Here, the distances from the swing center to the fixed weight 11 and the moving weight 13 are Rf and Rm, respectively, and the masses of the fixed weight 11 and the moving weight 13 are mf and Rf, respectively.
In mm, the inertia moment I of the lure 10 with respect to the swing center is I = Rf × mf + Rm × mm. Although the masses mf and mm of the fixed weight 11 and the moving weight 13 are always constant values, the distances Rf and Rm from the swing center to the fixed weight 11 and the moving weight 13 are fixed when the lure 10 is flying, as described above. 11 and the moving weight 13 are at the most distant positions and have the maximum value, the inertia moment I of the main body 12 with respect to the swing center also has the maximum value from the above equation, and the main body 12 is in a state where it is difficult to swing. There is.

Therefore, the lure 10 does not rock even when subjected to air resistance, and flies in a stable attitude with the tail 12c facing forward, and as a result, the landing point 26A at a farther position.
And landing point 26B when using the conventional lure 1
The flight distance can be extended compared to.

If the moment of inertia I is large, the lure 10
The reason why is difficult to swing is as follows. That is, the moment N of the force when an object of mass m is rotating at the angular velocity ω on the circumference of radius r from the center of rotation is N = I × dω / dt
Expressed as Where t is time and dω / dt
Is the angular acceleration obtained by differentiating the angular velocity ω with time t. On the other hand, the moment of inertia I is represented by I = mr ² , and when this is substituted into the above equation, N = I × dω / dt = mr ² ×
It becomes dω / dt. By transforming the above equation, dω / dt = N
/ I = N / mr ² , and when the radius r becomes large, the radius r
This is because the angular acceleration dω / dt decreases in inverse proportion to the square of.

On the other hand, in FIGS. 13 to 15, when the fishing line 16 is pulled in the direction of arrow C during the swim, the lure 10 also moves in the direction of submersion in water, that is, the direction of arrow D, and the rolling guide. Since the portion 12a tilts forward, the moving weight 13 that has been at the end of the rolling guide portion 12a (the position farthest from the fixed weight 11).
Rolls in the rolling guide portion 12a from the rear to the front, is contained in the hollow portion 11a of the fixed weight 11, and stops.

At this time, the center of gravity of the lure 10 is at the position of the fixed weight 11, and the center of swing of the lure 10 is almost at the same position as the center of gravity of the lure 10. Therefore, in the equation of inertia moment I = mr ² , r Is almost 0, and the moment of inertia I is also a very small value of approximately 0.

On the other hand, the lure 10 which is pulled by the fishing line 16 and advances in the direction of the arrow D is formed with a plate-shaped lip 12d protruding from the front portion of the main body 12, so that the lure 10 is underwater in the direction of the arrow D. The lip 12d
A hollow portion is generated in the rear of the lip, and so-called Karman vortices are alternately formed in the rear of the lip 12d. Since the pressure of the Karman vortex is lower than the pressure in front of the lip 12d, a force for pushing the lip 12d rearward alternately to the left and right acts due to the pressure difference, and a force to swing the main body 12 acts. .

At this time, the inertia moment I with respect to the swing center of the lure 10 is a very small value as described above, and the angular acceleration dω / dt is dω / dt = N /
As can be seen from the equation of I = N / mr ² , in FIG. 14, a large angular acceleration dω / dt acts on the main body 12, and the main body 12 is centered around the center of gravity G of the lure 10 which is the swing center. Swing in the direction of arrows E and F with a crisp and sharp action. Along with this, the hook 14
Also swings in the directions of arrows H and J.

In practice, the lure 10 is pulled by the fishing line 16 and is moving in the direction of the arrow D. Therefore, in FIG. 15, the forward movement and the swinging movement are combined and the lure 10 moves.
Swings left and right, moves forward in the direction of arrow K, and performs a pseudo-fish action.

Further, in the lure 10 in which the fixed weight 21 and the movable weight 24 of the second embodiment shown in FIGS. 9 and 10 are arranged in the main body 12, the movable weight 24 is attracted to the bottom plate 23 by the magnetic force during the swim. Therefore, even if the operation of pulling the fishing line 16 is interrupted or the posture of the lure 10 becomes unstable due to an obstacle, the moving weight 24 does not separate from the bottom plate 23 and stably stops in the hollow portion 22a. It is contained and the moment of inertia I is kept small. Therefore, as soon as the fishing line 16 is pulled, the crisp and sharp action is resumed.

If the lure is extremely raised or submerged in the water due to the weight balance of the entire main body, the auxiliary weight 31 may be placed in the main body 12 in front of or behind the fixed weight 11 as necessary. It may be fixedly arranged and the weight balance of the entire body may be adjusted. In this case, since the weights are dispersed, the moment of inertia I at the time of a swim tends to be a little larger, and the swinging action tends to be less sharp.

As described above, both characteristics contradictory to the improvement of the flight distance and the crisp and sharp action, which have been thought to be impossible in the past, have been made compatible by providing the ideal characteristics. You can achieve good results.

[0034]

According to the present invention, the fixed weight having the hollow portion as described above is arranged forward from the vicinity of the center of the main body in the longitudinal direction, and is formed in communication with the hollow portion toward the rear of the main body. A moving weight that is movable from the front to the rear or from the rear to the front in the rolling guide part is provided.

During a swim, the moving weight is contained in the hollow part of the fixed weight, and all weights are concentrated from near the center in the longitudinal direction of the body to near the tip to reduce the moment of inertia of the body and make it easier to swing. It has the effect of simultaneously increasing the number of fish and a sharp action that closely resembles the movement of a real fish, and as a result, it can expand the fishing area and improve the biting of the fish. It has the effect of increasing the catch.

Further, since the stationary weight having the hollow portion is formed of a magnet and the movable weight is made of a magnetic material, the movable weight is magnetically attracted to the stationary portion to be contained during the swiming. The effect that the moving weight can be stably stopped in the hollow part of the fixed weight even if the posture of the main body changes due to acceleration due to external force such as waves or the main body moves in any direction. Moreover, as a result, it is possible to obtain an effect that a stable and sharp action can be surely obtained.

Further, the attraction force of the moving weight by the magnet is set so that the magnetic force is smaller than the centrifugal force acting on the moving weight during casting, so that the moving weight resists the magnetic force during casting and the fixed weight. It is possible to move it away from the rear, and as a result, it is possible to stabilize the flight attitude and increase the flight distance by greatly increasing the moment of inertia with respect to the swing center of the whole body during casting. is there.

Another object is to add the auxiliary weight to the moving weight and the fixed weight, and fix the auxiliary weight inside the main body in front of or behind the fixed weight. Therefore, the weight balance of the whole main body can be adjusted. The effect is that the lure can be adjusted so that it does not rise or sink too deep in the water.
