Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lure with a movable center of gravity.

[0002]

2. Description of the Related Art As is well known, a lure used for lure fishing has a weight moving chamber which runs longitudinally inside the abdominal portion of a lure body having a small external shape, and the weight moving chamber is reciprocated. 2. Description of the Related Art There is a center-of-gravity moving lure in which a moving spherical movable weight body is incorporated.

[0003] JP-A-2000-236779 discloses that
It has a weight that can move in the front-rear direction inside the lure body, and when the rear end side is thrown forward, the weight moves from the front end side to the rear end side due to inertia, and when it lands, the weight In a center-of-gravity moving lure configured to be held back to the front end side, the weight has a sealed cylindrical case forming a weight moving space in which the weight is accommodated so as to be movable in the front-rear direction. A weight housing capsule configured to hold the weight at the front end side of the luer body is provided inside the lure body.

Japanese Utility Model Registration No. 2578193 discloses a crank bait lure provided with a diving plate attached to the tip of a lure body and a balance weight built in the lure body. By rolling, it is configured to be movable along the longitudinal direction so as to be able to move to the frontmost part of the lure body, a pocket is provided at the tip of the guide, and the balance weight can be held in the pocket. In addition, there is disclosed a lug in which a fishing line is tied to the diving board protruding from the tip of the lure body.

In the conventional lure with a movable center of gravity as disclosed in the above-mentioned publication, during casting, the movable weight body moves to the rear end side of the weight moving chamber, and the center of gravity of the entire lure moves to the rear part of the lure body which is optimal for casting. During the electrophoresis, the movable weight body moves to the front end side of the weight moving chamber at the time of electrophoresis, and the movable weight body is held by the holding section provided at the front end of the weight moving chamber, so that the center of gravity of the entire lure is optimal for electrophoresis. It concentrates on the front of the lure body.

[0006]

The lure movement during electrophoresis is a factor that enhances the fish-collecting effect of the lure. However, the conventional center-of-gravity moving lure as disclosed in the above-mentioned publication is movable during electrophoresis. Since the weight body is held by the holding portion provided at the front end of the weight moving chamber, the migration balance of the lure is stabilized, but the movement of the movable weight body in the weight moving chamber is restricted, and the center of gravity of the entire lure is reduced. Since it is fixed to the front part of the lure main body, it has been difficult to intentionally cause the fish to perform an interesting irregular movement by operating the fishing rod and the reel.

[0007] Another factor that enhances the fish collecting effect of the lure is a sound or vibration generated in the lure. In the conventional center-of-gravity moving luer disclosed in the above-mentioned publication, the movable weight body has a weight moving chamber. Since the bottom surface of the weight moving chamber is formed so as to be able to smoothly roll, the movable weight body rolls so as to slide on the smooth bottom surface of the weight moving chamber, and the movable weight body is moved by the weight moving chamber. No sound or vibration was generated from the lure simply by rolling the bottom.

Accordingly, the present invention provides a fish which can be made to intentionally perform an unusual movement of interest by operating a fishing rod and a reel, and that the movable weight body simply rolls back and forth in the weight moving chamber. As a technical issue, to obtain a lug with a movable center of gravity that generates vibrations and vibrations, as a result of repeated research and experiments to achieve this, weight movement running in the longitudinal direction inside the abdominal part of the lure body with a small external shape In a center of gravity movable luer in which a chamber is formed and a spherical or cylindrical movable weight body that reciprocates and rolls the weight moving chamber in the longitudinal direction, a lug fixed inside the tail portion of the lure body. Each weight of the one weight body and the second weight body fixed inside the head part of the lure main body is lured when the movable weight body is located at the head part side position of the weight moving chamber. Achieving the remarkable knowledge that the center of gravity of the body should be adjusted to concentrate on the tail part side from the center of the lure body and that the bottom surface of the weight moving chamber should be formed in a continuous uneven shape, achieving the technical problem It was done.

[0009]

The technical problem can be solved by the present invention as described below.

That is, the lug for moving the center of gravity according to the present invention comprises:
A weight moving chamber that runs in the longitudinal direction is formed inside the abdominal part of the lure main body having an external small fish shape, and a spherical or cylindrical movable weight body that reciprocates in the weight moving chamber in the longitudinal direction is incorporated. A center-of-gravity movable luer in which a first weight body is fixed inside a tail part of the lure body and a second weight body is fixed inside a head part of the lure body; The bottom surface of the moving chamber is formed in a continuous uneven shape, and the movable weight body can roll while repeatedly colliding with each projection of the uneven shape, and the movable weight body is located at a position on the head part side of the weight moving chamber. The weights of the first weight body and the second weight body are adjusted so that the center of gravity of the entire lure is more concentrated on the tail part side than the center of the lure body when located.

Further, in the present invention, in the lug with the movable center of gravity, the uneven shape is formed in a continuous vertical mountain shape.

A top-water-type center-of-gravity moving luer (hereinafter, referred to as a lug) that migrates near the water surface and includes a hook hanger 6 for stopping and a ring 7 to which a fishing line projecting forward from the head of the lure body 2 is attached. Simply called "Lure").

A weight fixing chamber 9 is formed in the lure main body 2 at the tail portion by partitioning the inside of the tail portion with a vertical rib 8. The weight fixing chamber 9 is formed at the tail portion from the bottom inner surface of the belly portion where the hook hanger 4 is located. A central longitudinal rib 10 concavely curved on the tail site side running toward the inner surface of the upper part,
A hollow portion on the abdominal part side formed by laying the central horizontal rib 13 running from the middle position of the central vertical rib 10 to the vicinity of the upper end of the vertical rib 8 is erected on the tail part side of the hollow part. A small vacant space 14 on the tail part side and a weight moving chamber 15 on the head part side are formed by partitioning the wall, and a part of the inner surface of the bottom part of the head part is partitioned by an inverted U-shaped rib 11 to fix the weight. A chamber 12 is formed.

In the weight moving chamber 15, one spherical large-diameter movable weight body 16 and two spherical small-diameter movable weight bodies 17, 17 are incorporated.
The bottom surface 18 is formed in a continuous vertical cross-section mountain shape in which the movable weight members 16, 17, 17 roll. Also, left and right lateral ribs 19, which project toward the longitudinal direction of the weight moving chamber 15, are provided on both side surfaces of the weight moving chamber 15.
20 are provided so as to be opposed to each other with a gap through which the large-diameter movable weight body 16 can pass (see FIG. 2). The right lateral rib 19 and the left lateral rib 20 regulate the movement of the movable weight members 16, 17, 17 in the short direction.

Each of the movable weights 16, 17, 17 housed in the weight moving chamber 15 has a small-diameter movable weight 17, 17 located before and after the large-diameter movable weight 16 in the weight moving chamber 15. Are arranged as follows.

In the weight fixing chamber 9, one spherical large-diameter first weight body 21 and one spherical small-diameter first weight body 22 are fixed.
, One spherical small-diameter second weight body 23 is fixed.

The weights of the first weight members 21 and 22 and the second weight member 23 are equal to the weight moving chamber 15.
When the three movable weight bodies 16, 17, 17 incorporated in the lure 1 are located at the front end (head side position) of the weight moving chamber 15, the center of gravity of the entire lure 1 is slightly tailed from the center of the lure main body 2. It is adjusted to concentrate on the site side.

Next, the operation will be described.

FIG. 3 is an explanatory side view showing the state of casting the lug with the movable center of gravity shown in FIG. 1, and FIG. 4 shows the state of the lure with the movable center of gravity shown in FIG. 1 during floating and electrophoresis. FIG. 5 is an explanatory plan view showing an electrophoretic state of the lure when the fishing line tied to the ring of the movable center lure shown in FIG. 1 is continuously pulled by the operation of the fishing rod and the reel. FIG. 6 is an explanatory view showing a state in which the center of gravity movable lure shown in FIG. 1 is tilted forward, and in these figures, a front hook and a rear hook are omitted, and a weight moving chamber is provided. 1 and FIG. 2 indicate the same or corresponding parts.

When the lug 1 with movable center of gravity according to the present embodiment is cast, as shown in FIG. 3, each movable weight body 16, 17, 1 built in the weight moving chamber 15 is moved.
7, the movable weight members 16, 17, 17
The lure 1 moves to the rear end of the weight moving chamber 15 due to the inertial force acting on the lure 1, and the center of gravity of the entire lure 1 is concentrated on the tail portion of the lure main body 2. The lure 1 can be cast far away because it flies while maintaining its posture toward the head and does not receive a large air resistance during the flight.

Then, the cast lure 1
, The tail part is directed downward, so that even after the landing, the movable weight members 16, 17, 17 remain at the rear end of the weight moving chamber 15, and the center of gravity of the entire lure 1 is In order to concentrate on the tail part, the lure 1 rises to the water surface with the head part directed upward, and then, as shown in FIG. Floating in a vertical position.

Next, when the fishing line 24 tied to the ring 7 of the lure 1 is pulled by the operation of the fishing rod and the reel, as shown in FIG. 4B, the fishing line 24 floats in a posture substantially perpendicular to the water surface. The lure 1 which has been protruded from the water surface vigorously falls forward on the head portion, hitting the water surface with the head portion and splashing the water so that the lure 1 has an inclined posture substantially parallel to the water surface. At this time, each of the movable weight members 16, 17, 17 located at the rear end of the weight moving chamber 15 is integrally formed with each of the vertical cross-section mountain-shaped projections formed on the bottom surface 18 of the weight moving chamber 15. Since the bottom surface 18 rolls and moves to the front end of the weight moving chamber 15 while repeating collision with the lure 1, a continuous collision sound is generated from the lure 1 and the lure main body 2 vibrates little by little.

Further, when the fishing line 24 is continuously pulled by the operation of the fishing rod and the reel, the lure 1 keeps the inclined posture substantially parallel to the water surface, and the movable weight members 16, 17, 17 are moved to the weight moving chamber. The lure 1 stops at the front end of the lure 1 and the center of gravity of the entire lure 1 is slightly concentrated on the tail portion side from the center of the lure main body 2, so as shown in FIG. Meandering as if to slide, and migrate around the water surface as if small fish escaped. At this time, each movable weight body 16, 17,
Numeral 17 reciprocates slightly at the front end of the weight moving chamber 15 in accordance with the migration of the lure 1, and each of the movable weight bodies 16, 17, 17 is moved to the bottom surface 1 of the weight moving chamber 15.
Since the lure 1 collides with the mountain-shaped projection formed in the vertical section 8, a collision sound is generated from the lure 1 and the lure main body 2 vibrates little by little.

Next, when the fishing line 24 is loosened by operating the fishing rod and the reel, as shown in FIG.
Holds the inclined posture for a certain period of time, but since the center of gravity of the entire lure 1 is slightly concentrated on the tail part side from the center of the lure main body 2, the lure 1 is gradually inclined backward. At this time, first, the large-diameter movable weight member 16 of the movable weight members 16, 17, 17 located at the front end of the weight moving chamber 15, and the tail of the luer body 2 more than the large-diameter movable weight member 16. The small-diameter movable weight body 17 located on the part side starts rolling at the same time, and subsequently, the small-diameter movable weight body 17 located on the head part side of the lure main body 2 with respect to the large-diameter movable weight body 16 becomes another movable body. Rolling starts after the weight bodies 16 and 17 are delayed. Accordingly, the large-diameter movable weight body 16 and the small-diameter movable weight body 17 that have started rolling earlier repeatedly roll on the bottom surface 18 while repeatedly colliding with the respective projections formed on the bottom surface 18 of the weight moving chamber 15. Even after reaching the rear end of the moving chamber 15, the small-diameter movable weight body 17 that started rolling with a delay rolls on the bottom surface 18 while repeatedly colliding with each protrusion formed on the bottom surface 18 of the weight moving chamber 15. As a result, a continuous collision sound is generated from the lure 1 for a long time, and the lure main body 2 vibrates little by little. Then, when the center of gravity of the entire lure 1 is concentrated on the tail portion of the lure main body 2 as the movable weight members 16, 17, 17 move, the lure 1 comes to the water surface again with the head portion protruding above the water surface. The robot floats in a posture substantially perpendicular to the vehicle (see FIG. 4A).

When the fishing line 24 is intermittently pulled by the operation of the fishing rod and the reel, the lure 1 swings its head part back and forth, bows, and migrates as if a weak small fish is struggling on the water surface. At this time, each movable weight body 1
6, 17, and 17 reciprocately roll on the bottom surface 18 while repeatedly colliding with each of the projections having a vertical cross section formed on the bottom surface 18 of the weight moving chamber 15, so that a continuous collision sound is generated from the lure 1. At the same time, the lure body 2 vibrates little by little.

By adjusting the pulling force of the fishing line 24 by operating the fishing rod and the reel, as shown in FIG. 6, the angle θ at which the lure 1 tilts the head forward can be adjusted intentionally. For example, when the fishing line 24 is pulled with a weak force by the operation of the fishing rod and the reel, the lure 1 floating in a posture substantially perpendicular to the water surface (shown by a solid line in the figure) slightly moves the head portion of the lure 1. defeat forward by an angle theta ₁ (in the figure, indicated by a dashed line.). At this time, the movable weight members 16, 17, 17 located at the rear end of the weight moving chamber 15 slightly move to the tip end side of the weight moving chamber 15, and the center of gravity of the entire lure 1 is also shifted to the lure main body 2. Is slightly moved to the side of the head part, and the lure 1 temporarily moves the head part to a small extent in the left-right direction and migrates.

Further, when the fishing line 24 is pulled by the operation of the fishing rod and the reel with a stronger force than the weak force, the lure 1 floating in a posture substantially perpendicular to the water surface causes the head portion of the lure 1 to move by the angle θ. ₁ tilted forward by a large angle theta ₂ than (shown by a chain double-dashed line.). At this time, each movable weight body 1 located at the rear end of the weight moving chamber 15
6, 17, 17 largely move toward the distal end of the weight moving chamber 15 as compared to when the fishing line 24 is pulled with a weak force, and the center of gravity of the entire lure 1 also largely moves toward the head part side of the lure main body 2. Therefore, the lure 1 temporarily moves the head part largely in the left-right direction and migrates.

Further, when the fishing line 24 is pulled by a certain force or more by operating the fishing rod and the reel, the lure 1 floating in a posture substantially perpendicular to the water surface moves the head portion of the lure 1 by the maximum angle θ _MAX. It is tilted forward to assume an inclined posture substantially parallel to the water surface (indicated by a dotted line in the figure). At this time, the movable weight members 16, 17, 17 located at the rear end of the weight moving chamber 15 are
Of the lure 1 and the center of gravity of the entire lure 1
Is slightly moved to the tail part side from the center of the lure, and the lure 1 temporarily shakes the head part in the left-right direction as much as possible to migrate (see FIG. 5).

According to the present embodiment, the three movable weight members 16, 17, 1 built in the weight moving chamber 15 are provided.
7 can be freely reciprocated without being held at a specific position in the weight moving chamber 15, and when each of the movable weight bodies 16, 17, 17 is located at the front end of the weight moving chamber 15, Since the weights of the first weight bodies 21, 22 and the second weight bodies 23 are adjusted so that the center of gravity of the entire lure 1 is concentrated on the tail part side from the center of the lure main body 2, the fishing line 24 is operated by operating the fishing rod and the reel. The movable weight members 16, 17, 17 can be moved to the front end side of the weight moving chamber 15 by pulling, and the movable weight members 16, 17, 17 can be moved by loosening the fishing line 24 by operating a fishing rod and a reel. Can be moved to the rear end side of the weight moving chamber 15, so that each movable weight body 16 in the weight moving chamber 15 can be moved by operating a fishing rod and a reel. 17, 17 can adjust the position of, since the center of gravity of the entire lure 1 can be moved intentionally, it is possible to intentionally irregular motion lure 1.

Further, according to the present embodiment, since the bottom surface 18 of the weight moving chamber 15 is formed in a continuous vertical cross section, each movable weight body 16, 17, 17 built in the weight moving chamber 15 is formed. Is the bottom 1 of the weight transfer chamber 15
8 is reciprocated, the movable weight members 16, 1
Since the lugs 1 and 7 repeatedly collide with the respective protrusions having a vertical cross section formed on the bottom surface 18, a continuous collision sound and vibration are generated from the lure 1, and the fish collecting effect can be enhanced.

In the lure 1 according to the present embodiment, spherical weights are used for the three movable weights 16, 17, and 17 built in the weight moving chamber 15, but the bottom surface 18 of the weight moving chamber 15 is used. Any shape can be used as long as it can roll, and for example, a cylindrical weight body may be used. However, when the cylindrical weight body is housed in the weight moving chamber 15, it must be housed so that the peripheral wall of the cylindrical weight body contacts the bottom surface 18 of the weight moving chamber 15. Moreover, you may change each number of a movable weight body, a 1st weight body, and a 2nd weight body.

The front hook 3 and the rear hook 5
May be locked to the hook hangers 4 and 6 via an annular locking tool (not shown).
