Description

  The present invention relates to a lure used for fishing, and more particularly to a lure of a type having a weight inside and moving the weight.

  2. Description of the Related Art A center-of-gravity moving lure that includes a weight in a luer body and that can move in the axial direction within the lure body has been widely provided (see, for example, Patent Document 1).

  In such a center-of-gravity movement type lure, the weight moves to the tail side during casting of the lure with the tail side as the flying direction, and the flight distance is extended. When migrating after landing, the weight moves toward the head and stabilizes the lure's migrating posture.

  In such a center-of-gravity movement type lure, a holding means for holding the weight on the head side at the time of migration is further provided so that the weight is stably positioned on the head side at the time of migration and the weight does not move. A lure has also been proposed.

For example, in the lure of the above-mentioned patent document 1, the weight storage part to which a weight moves is inclined, and the weight is positioned on the head side. In another lure, a magnet is provided on the head side of the weight storage portion, the weight is made a magnetic body, and the weight is held by the magnet on the head side (see Patent Document 2).

  However, the means for holding the weight of the center-of-gravity moving lure that has been conventionally provided as described above is not sufficient. For example, in the technique as described in Patent Document 1 described above, the weight is not held on the head side depending on the posture of the lure. Moreover, in the method of the above-mentioned patent document 2, the weight which can be utilized will be restrict | limited to a magnetic body. Other technologies have also been proposed, but further improvements are required.

  The present invention provides a center-of-gravity moving lure capable of reliably moving and holding a weight.

The lure of the present invention is a lure used for fishing, and has a luer body having a weight housing portion extending in the axial length direction therein, and a spherical weight disposed in the weight housing portion and movable in the axial length direction within the weight housing portion. And a restriction state that restricts movement of the weight toward the tail side, a first permission state that allows movement of the weight toward the tail side, and toward the head side of the weight. And a regulating valve capable of adopting any state of the second permissible state permitting the movement of.

  When casting, this lure flies with the tail side of the lure body as the flight direction, the weight arranged in the weight storage part of the lure body moves in the weight storage part toward the flight direction (tail side), Move the center of gravity of the lure body to the tail side to stabilize the flight posture of the lure body. On the other hand, after landing, the weight moves the weight storage part toward the head side to stabilize the migration posture.

  When such a weight moves in the weight housing portion, the regulating valve acts as follows. First, there is a state in which the weight is located on the head side of the weight storage portion. In this state, when the weight attempts to move to the tail side in the weight housing portion, the weight hits the restriction valve, and the restriction valve restricts the movement of the weight to the tail side (restricted state). When a large moment in the tail direction is generated in the weight as in casting, the restriction valve is allowed to move to the tail side of the weight (first allowable state). The weight moves to the tail side in the weight housing part, and the center of gravity moves to the tail side. Thereafter, when the lure lands, the weight moves again to the head side, and the restriction valve permits the movement of the weight (second allowable state). Then, unless a large moment is generated in the direction of the tail of the weight as in casting, the weight is stably positioned on the head side of the weight storage portion.

  The weight storage portion may have an inclined portion that is inclined downward toward the tail side and a pocket portion that is formed at the head side end of the inclined portion and falls downward one step from the inclined portion. The regulating valve is provided on the inner peripheral surface on the tail side of the pocket portion.

  In such a weight storage portion, during casting, the weight over the first permissible body of the restriction valve moves smoothly toward the tail portion along the inclination of the inclined portion. Further, when the weight is located on the head side of the weight storage portion, it is in the pocket portion, and does not move to the tail side toward the tail side.

  Further, for example, this lure further includes a rotation shaft extending in the left-right width direction of the lure body formed near the inner wall surface on the tail side of the pocket portion, and a relief portion formed in the vicinity of the rotation shaft. It may be a thing. This restriction valve is a valve having elasticity that protrudes into the weight housing portion while being rotatably mounted on the rotation shaft. The restriction state of the restriction valve is a state in which the restriction valve rotates in the direction of the tail and protrudes into the weight housing part. The first permissible state is that the restriction valve is inclined to the tail side due to its elasticity in the restriction state. The second permissible state is a state in which the restriction valve rotates in the head direction and at least a part of the restriction valve is retracted from the weight storage part into the escape part.

  When using such a restriction valve, the restriction valve moves as follows. First, there is a state in which the weight is located on the head side of the weight storage portion. In this state, if the weight attempts to move to the tail side in the weight housing part, the restriction valve rotates to the tail part centering on the turning shaft and protrudes into the weight housing part, and the weight hits the protruding restriction valve. Regulates the movement of the weight toward the tail (regulated state).

  Next, when a large moment in the tail direction occurs in the weight as in casting, the restriction valve bends further from the restriction body toward the tail due to its elasticity, and allows the weight to move toward the tail. (First allowable state). The weight moves to the tail side in the weight housing part, and the center of gravity moves to the tail side.

  After that, when the lure lands, the weight moves again to the head side, the restriction valve also turns to the head side around the rotation axis toward the head side, and a part of the restriction valve is retracted into the escape portion. Then, the weight is allowed to move to the head side in the weight housing portion, and the movement of the weight is allowed (second allowable state). Then, unless a large moment is generated in the direction of the tail of the weight as in casting, the weight is stably positioned on the head side of the weight storage portion.

  According to such a lure of the present invention, it is possible to reliably move and hold the weight.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a lure employing one embodiment of the present invention has a hollow luer body 1 having an outer shape resembling a fish. The lure body 1 is a synthetic resin member formed by bonding a pair of left and right halves on the opening side, and a fishing line locking portion for locking a fishing line provided at the head side end. 2, a lip portion 3 projecting obliquely downward on the lower surface of the head, and eyes 4, 5 for connecting fishhooks respectively provided near the abdomen and tail. The fish hook locking portions 2 and the eyes 4 and 5 are arranged in a concave recess formed in the bonded portion of the opening surface of the half member, and are fixed together when the half member is bonded and fixed. . The lip 3 is formed integrally with the front lure body 1.

  Various paints are applied to the peripheral surface of the lure body 1 to resemble the appearance of a fish. For example, eyes or scale patterns may be drawn. The lip portion 3 is a portion for receiving a water flow and tilting the lure head side toward the bottom of the water. The fish hook locking part 2 and the eyes 4 and 5 can use the same kind of parts. These are “eight-letter-shaped” members having ring portions at both ends. One ring protrudes from the bonding surface of the luer body 1 and the other protrudes outward from the luer body 1. A fishing hook or the like is connected to the ring on the side projecting outward of the lure body 1 via a fishing line or a split ring.

  Further, a part of the lure body 1 near the hollow abdomen is separated from other parts, and a weight storage part 6 extending in the axial direction is formed. Two weights 7 are stored in the weight storage portion 6. Furthermore, a stopper 8 is provided on the inner wall surface on the head side of the weight storage portion 6.

  The weight storage part 6 is formed on the tail side from the vicinity of the center of the lure body 1 in the axial direction. The weight storage part 6 is divided into an inclined part slightly inclined downward (toward the abdomen side of the lure body) toward the tail part, and a pocket part that has fallen one step below the inclined part on the head side of the inclined part. it can. The pocket portion is large enough to accommodate two weights 7. A stopper 8 is provided on the inner wall surface in the vicinity of the inclined portion on the tail side of the pocket portion that is stepped down one step.

  The weight 7 is formed in a spherical shape by mixing a metal such as lead or tungsten or a metal powder such as lead or tungsten into a rubber resin.

  As shown in detail in FIG. 2, the stopper 8 is a part formed of a synthetic resin such as PP. A part corresponding to the inner wall of the weight housing portion 6 of the luer body 1 is recessed one step from the bonding surface of the luer body 1 to form a stopper housing portion 1a, and the stopper 8 is disposed in the stopper housing portion 1a. The Specifically, the stopper housing 1a is formed with a rotation shaft extending in the left-right width direction of the lure body 1, and the stopper 8 is rotatably disposed on the rotation shaft.

  The stopper 8 includes a ring portion 10 having a through-hole formed at the center and a valve portion 11 extending from the ring portion 10. The rotation shaft of the stopper storage portion 1a is inserted into the through hole of the ring portion 10, and the stopper 8 rotates about the rotation shaft. The stopper accommodating portion 1a is large enough to accommodate the ring portion 10, and particularly, a large space is secured toward the head side. The valve portion 11 of the stopper 8 is a valve-like thin plate portion extending from the ring portion 10 so as to protrude into the weight storage portion 6 from the stopper storage portion 1a. The valve portion 11 is curved toward the tail portion of the lure as a whole, and warps in the head direction at the head end.

  This stopper 8 rotates as described above. FIG. 2A shows a state in which the stopper 8 rotates most in the direction of the tail and the valve portion 11 comes into contact with the inner wall on the tail side of the stopper housing 1a. In this state, the distance (see ΔX) between the head end of the valve portion 11 and the inner wall on the opposite side of the weight storage portion 6 is adjusted to be smaller than the diameter of the weight 7. This state is a restricted state.

  Further, when force is applied to the valve portion 11 in the tail direction in this restricted state, the head end of the valve portion 11 that is warped in the head direction is curved toward the tail portion, and the head end of the valve portion 11 and the weight storage portion 6 The distance from the opposite inner wall is larger than the diameter of the weight 7. This state is the first allowable state (see FIG. 2B).

  Next, FIG. 2 (c) shows a state where the stopper 8 is rotated in the most head side direction and the valve portion 11 is in contact with the inner wall on the head side of the stopper storage portion 1a. In this state, a part of the valve portion 11 is retracted from the weight storage portion 6 to the space (escape portion) of the stopper storage portion 1a, and the distance (ΔX) between the head end of the stopper 8 and the opposite inner wall of the weight storage portion 6 is reached. Is sufficiently larger than the diameter of the weight 7. This state is the second allowable state.

  In the thus configured lure, first, as shown in FIG. 1, the weight 7 is in the pocket portion of the weight storage portion 6. When the fishing line is locked to the fishing line locking part 2 and the lure is cast in the water, the lure body 1 flies with its tail side flying in the casting direction, and the weight 7 arranged in the weight storage part 6 is used. Moves in the weight storage part 6 toward the tail side. Due to the momentum of the flight, the stopper 8 also turns to the tail side, and the stopper 8 is once regulated (see FIG. 2A), but the head end of the stopper 8 is further curved to the tail side by the collision of the weight 7, The first allowable state is entered (see FIG. 2B). Then, the weight 7 moves to the inclined portion in the weight storage portion 6, reaches the tail side end of the weight storage portion 6, and stabilizes the flying posture of the lure body 1. This makes it easier to throw a lure to a distant target point.

  Thereafter, when the lure migrates in the water after the lure has landed, the lip 3 receives the water flow and tilts the head side toward the bottom of the water. Then, the weight 7 moves to the head side in the weight storage part 6. At the same time, the stopper 8 is also turned to the head side, the stopper 8 is in the second permissible state (see FIG. 2C), and the weight 7 is positioned again in the pocket portion of the weight storage portion 6. Then, the position of the center of gravity moves to the head side, and the lure migration posture is stabilized. In this state, the lure body 1 may vibrate during migration and the weight 7 may move from the pocket portion toward the inclined portion. However, even if the weight 7 moves to the tail side in the weight housing portion 6, the stopper 8 is in a restricted state (see FIG. 2A), and the weight 7 does not accidentally jump out of the pocket portion.

1 is a cross-sectional view of a lure that employs one embodiment of the present invention. The figure which showed the motion of the stopper 8. FIG.
