Description

  The present invention relates to the structure of a lure used for fishing, particularly a joined plug.

  In lure fishing, the angler invites the target fish bite by casting the lure and retrieving the lure to resemble the movement of the fish and insects that bait. The manner of retrieve of lures is quite various, and the angler directs the bait movement intended by himself by devising the retrieve. In addition, the lure structure has been improved in various ways to produce bait movement, and in addition to general hard lures such as plugs, flexible soft lures such as worms are also provided. (For example, refer nonpatent literature 1).

  In order to produce the movement of a bait fish that swims in the vicinity of the surface of the water, a lure called a joined plug has been provided. This type of lure has a lure body and a hook attached to the lure body, but the lure body is divided in the front-rear direction, and each of the divided lure bodies is relatively rotatable. . Therefore, when such a joined plug is retrieved at a low speed, a characteristic movement in which the bait fish with weak physical strength swims in the vicinity of the water surface is produced. In other words, the joined plug is suitable for the angler to produce a bait fish movement with weak physical strength, and the angler preferably uses the joined plug according to the situation of the fishing ground.

  However, there is a problem that the joined plug tends to lose its balance when retrieved, and is not particularly suitable for high-speed retrieval. Therefore, the present invention was made for the purpose of improving the structure of the joined plug, and the movement of the bait fish that swims in the vicinity of the surface of the water is easily and realistically produced, and is also retrieved at high speed. It is to provide a lure (joined plug) that does not lose its balance even if it is applied.

  In order to achieve the above object, a lure according to the present invention includes a luer body in which a front main body and a rear main body are rotatably connected via a hinge structure. And the center of gravity of the rear main body is set to a position where the rear main body floats with the abdomen side up in the water.

  In order to achieve the above object, the lure according to the present invention includes a luer body in which a front body and a rear body are rotatably connected via a hinge structure. The present invention is located below the centroid of the cross section of the front body, and the center of gravity of the back body is located above the centroid of the cross section of the back body where the center of gravity exists. Is.

  In the present invention, the direction in which the lure is retrieved is defined as “front direction”, and the water surface side of the lure in which the lure is retrieved is defined as “upper side” or “back side”. Therefore, the front main body of the lure is a portion of the lure main body in the direction of retrieval, and the rear main body of the rear is a portion connected to the front main body.

  The front main body floats with the back side up in the water, and the rear main body floats with the belly side (that is, the lower side) up in the water. Therefore, when the lure is cast, a twist occurs between the front body and the rear body, and the lure drifts on the surface of the water or in the water. When this lure is retrieved at a low speed, the rear body vibrates violently, so that the lure brings about the movement of bait fish with weak physical strength. In addition, the front body floats with the back side up, so that it can stably move underwater when retrieved at high speed. Since the rear body only follows the front body, the lure will not be greatly out of balance even when retrieved at high speed.

  According to the present invention, the front body floats with the back side up by setting the center of gravity position low, and the back body floats with the belly side up by setting the center of gravity position high. Therefore, since the lure drifts in the water, the angler can easily and realistically produce the movement of the bait fish with weak physical strength. In addition, since the front body is stable in water, the lure travels in water with a good balance even when it is retrieved at high speed. As a result, the lure can also invite a target fish reaction byte.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a front view of a lure according to an embodiment of the present invention. The lure 10 includes a front main body 11 and a rear main body 12, and both are rotatably connected. The front main body 11 and the rear main body 12 constitute a lure main body of the lure 10, and a hook (fishing hook) is attached to the lure main body as will be described later.

  FIG. 2 is an enlarged perspective view of a main part of the lure 10 and illustrates the structure of the connecting portion between the front main body 11 and the rear main body 12 in detail. As shown in the figure, the front main body 11 and the rear main body 12 are connected by a hinge 13. That is, the lure 10 is a joined plug, and is floated or retrieved near the water surface or near the water surface as will be described later.

  The front main body 11 and the rear main body 12 are made of, for example, resin, wood, and the like, and their forms are formed to be very similar to the form of bait fish. That is, the front main body 11 is configured to resemble the form from the head of the bait fish to the vicinity of the butt, and the rear main body 12 is configured to resemble the form from the butt to the tail of the bait fish. . Therefore, when the front main body 11 and the rear main body 12 are connected, the overall form is very similar to the form of the bait fish.

  A ring 14, a ring 16, a lip 15, and a weight 30 are provided at the front lower portion of the front main body 11. The weight 30 is embedded in the lower front part of the front main body 11. The material constituting the weight 30 is preferably a metal having a large specific gravity, typically a tungsten alloy. However, the material constituting the weight 30 is not limited at all, and other materials may be adopted. In the present embodiment, the weight 30 is formed in a spherical shape, but the shape of the weight 30 is not limited at all. The weight 30 determines the position of the center of gravity G1 of the front body 11 as will be described later. The front main body 11 has its center of gravity G1 set at a position to be described later by attaching the weight 30, the ring 14 and the like. Note that the weight 30 may be attached to another part, for example, the lip 15 or the like.

  The rings 14 and 16 are made of metal such as stainless steel, for example, and a line (fishing line) is connected to the ring 14. The angler retrieves the lure 10 by manipulating the line connected to the ring 14. The lip 15 is made of, for example, resin and is formed in a substantially rectangular plate shape. The lip 15 causes the front body 11 to be submerged in the water as the lure 10 is retrieved. The lip 15 serves as a wing for controlling the movement of the front main body 11 in water, and the shape of the lip 15 can be changed in various ways. Further, a hook (fishing hook) is attached to the ring 16.

  As shown in FIG. 2, a recess 17 that is recessed forward is provided at the rear end of the front main body 11. A stay 19 is attached to a wall surface 18 that defines the recess 17. The stay 19 is made of a metal such as stainless steel, for example, and is provided with a through hole 20 penetrating in the vertical direction. In the present embodiment, four stays 19 are provided along the vertical direction, but the number of stays 19 is not limited at all. Each stay 19 is fixed to the front main body 11, but also constitutes a part of the hinge 13.

  As shown in FIG. 1, a ring 21 is provided at the center lower portion of the rear main body 11. The ring 21 is made of a metal such as stainless steel, for example, and a hook (fish hook) is attached to the ring 21. Further, the rear end portion 22 of the rear main body 12 includes a substantially V-shaped groove 23. The groove 23 extends forward from the rear end of the rear body 12. A pair of flange members 24 are provided at the rear end portion 22. Each flange member 24 is made of a metal such as stainless steel, for example, and is formed in a thin plate shape.

  A pin 25 is disposed at the rear end portion 22. The pin 25 penetrates the rear end portion 22 in the left-right direction, and both end portions thereof are supported by the rear end portion 22. Each flange member 24 has a base end portion inserted into the groove 23, and the base end portion is rotatably supported by the pin 25. Accordingly, each flange member 24 can freely rotate and swing around the pin 25. When the lure 24 is retrieved, each flange member 24 swings violently. .

  As shown in FIG. 2, a connecting arm 26 is attached to the front end portion of the rear main body 12. The connecting arm 26 is made of a metal such as stainless steel. A through hole 27 penetrating in the vertical direction is provided at the distal end of the connecting arm 26. In the present embodiment, the recess 28 is provided on the front end surface of the rear main body 12 so that the attachment work of the connecting arm 26 is facilitated, but the recess 28 may be omitted. In the present embodiment, only one connecting arm 26 is provided, but the number of connecting arms 26 is not limited at all. The connecting arm 26 is fixed to the rear main body 12 but also constitutes a part of the hinge 13.

  As described above, the connecting arm 26, the flange member 24, and the like are attached to the rear main body 12, so that the center of gravity G2 of the rear main body 12 is set at a position described later.

  The hinge 13 includes a stay 19 fixed to the front main body 11, a connecting arm 26 fixed to the rear main body 12, and a hinge pin 29. The hinge pin 29 is made of a metal such as stainless steel and is formed in a columnar shape. In a state where the connecting arm 26 of the rear main body 12 is inserted between the stays 19, a hinge pin 29 is inserted between them. That is, the hinge pin 29 is inserted through the through hole 20 of each stay 19 and the through hole 27 of the connecting arm 26 and is supported by the stay 19. Thereby, the rear main body 12 can freely rotate in the left-right direction with respect to the front main body 11. The rear main body 12 can swing in the vertical direction with respect to the front main body 11 by setting the inner diameter dimension of the through hole 27 provided in the connecting arm 26 to be large.

  FIG. 3 is a front view of the front body 11 and shows the position of the center of gravity G1 of the front body 11. 4 is a cross-sectional view taken along the line IV-IV in FIG. 3, and shows a cross section A1 of the front main body 11 where the center of gravity G1 exists.

  The center of gravity G1 of the front main body 11 exists on the cross section A1, and is set at a position of a distance d1 upward from the lower edge of the cross section A1. Further, the centroid Z1 of the cross section A1 is present at a distance y1 upward from the lower edge of the cross section A1. The centroid Z1 indicates a position where J1 = S1 * y1 is established, where S1 is the cross-sectional area of the cross section A1 and J1 is the moment of inertia of the cross section. In the present embodiment, the distance y1 is larger than the distance d1. Accordingly, the center of gravity G1 of the front main body 11 is located below the centroid Z1 by a distance Δd1 on the transverse section A1. Thereby, the front main body 11 floats with the back side up in the water alone.

  FIG. 5 is a front view of the rear main body 12 and shows the position of the center of gravity G <b> 2 of the rear main body 12. FIG. 6 is a cross-sectional view taken along the line V-V in FIG. 5 and shows a cross section A2 of the rear main body 12 where the center of gravity G2 exists.

  The center of gravity G2 of the rear main body 12 exists on the cross section A2, and is set at a position of a distance d2 upward from the lower edge of the cross section A2. Further, the centroid Z2 of the cross section A2 exists at a distance y2 downward from the lower edge of the cross section A2. The centroid Z2 indicates a position where J2 = S2 * y2 is established, where S2 is the cross-sectional area of the cross section A2 and J2 is the first moment of section. In the present embodiment, the distance y2 is smaller than the distance d2. Accordingly, the center of gravity G2 of the rear main body 12 is located above the centroid Z2 by a distance Δd2 on the transverse section A2. As a result, the rear main body 12 floats with the ventral side facing up in the water alone.

  The angler connects a line to the ring 14 (see FIG. 1), and casts the lure 10 to a desired point using a fishing rod. Since the center of gravity G1 of the front body 11 of the lure 10 is set at the above-described position, the lure 10 floats with the back side up in water. On the other hand, the rear main body 12 of the lure 10 floats with the abdomen side up in the water because its center of gravity G2 is set at the aforementioned position. For this reason, when the lure 10 lands, a twist occurs between the front main body 11 and the rear main body 12, and the lure 10 drifts on the surface of the water or in the water.

  Therefore, when the lure 10 drifts on or near the water surface, the lure 10 is easily washed away by wind or waves. Further, when the lure 10 is retrieved at a low speed, the rear main body 12 oscillates violently, so that the lure 10 brings about the movement of bait fish whose physical strength has declined. As a result, the angler can easily and realistically produce the movement of the bait fish with weak physical strength.

  In addition, the front body 11 is set to have a low center of gravity G1 and floats with the back side up, so that the front body 11 proceeds stably underwater even when retrieved at high speed. Therefore, even when the lure 10 is retrieved at high speed, the lure 10 is not greatly out of balance, and as a result, the lure 10 can also invite the target fish reaction byte.

  In the present embodiment, the center of gravity G1 of the front main body 11 and the center of gravity G2 of the rear main body 12 are set at the aforementioned positions, but the positions of the respective center of gravity G1 and G2 may be set at other positions. Of course it is good. In short, the position of the center of gravity G1 is set so that the front body 11 floats with the back side up in the water alone, while the rear body 12 has the center of gravity so that it floats with the stomach side up in the water alone. The position of G2 should just be set.

  The present invention can be applied to a joined plug.
