Description

The present invention relates to a lure, and more particularly to a lure having a structure in which weights move inside a hollow.

Some lures, so-called plugs, have a movable weight inside the main body that looks like a small fish (see Patent Document 1), which stabilizes the flight attitude during casting and reeling. At times, it was possible to move the weights to move the center of gravity of the entire lure into place. In this type of lure, in addition to the configuration in which the weight rolls and moves inside the hollow of the lure body and the weight position is determined by fitting into a recess provided at a predetermined position (see Patent Document 1). , There was a structure in which magnetism was applied by a magnet instead of the concave portion (see Patent Document 2).

However, when the weight is moved by rolling, the hollow inside of the lure body must be smooth, and if burrs occur during manufacturing or if part of the material is damaged inside during use, the weight will roll. This would destroy the smooth state of the moving surface and hinder the smooth movement of the weight. Therefore, the applicant of the present application has developed a structure in which a shaft is arranged inside the lure body and the weight is moved along the shaft (see Patent Document 3).

In the case of this technology, a weight made of a magnetic material is movable, and the weight is magnetically attached to the weight to stop the movement. The magnet is provided at the tip of the moving region. Therefore, when the movement of the weight is stopped, it collides with the magnet, and the magnet may be damaged by the impact after being used many times. It can be used when the magnet is partially damaged and stays in its original position, but when the magnet is damaged to the extent that it cannot stay in the specified position, the movement of the weight cannot be stopped. There was concern that the situation would occur.

The present invention has been made in view of the above points, and an object of the present invention is to provide a lure capable of avoiding damage to a magnet due to movement of a weight even when the number of times of use is large. is there.

Therefore, in the present invention, the lure body having a hollow region inside, a regulated region provided linearly from the tail side to the head side in the hollow region, and a magnetic material movable along the regulated region. When the mobile weight is placed near the head end of the regulation area and the mobile weight moves to the head end, the magnetic force is not in contact with the outer surface of the mobile weight. It is characterized by being provided with a magnet that acts on the above.

According to the invention of the above configuration, the magnet has a configuration in which a magnetic force is applied to the mobile weight in a non-contact state, and the mobile weight moves along the regulated region. It is possible to avoid damage due to contact. Further, when the movable weight moves along the regulation area and is at a position appropriately separated from the magnet, it is not affected by the magnetic force of the magnet, but when it moves to a position extremely close to the magnet, The movement can be stopped by the action of the magnetic force. The regulated region can be formed by a linear shaft or by providing a moving space. When forming a moving space, it is preferable that the entire moving space is not formed in a tube shape, but is formed of, for example, a rail-shaped member in which three or more points are in sliding contact with each other in the cross section.

Further, the present invention comprises a lure body having a hollow region inside, a shaft made of a linear non-magnetic material having an axis arranged from the tail side to the head side in the hollow region, and a shaft inserted into the shaft. A moving weight made of a magnetic material that can move along the shaft, a stopper member that limits the moving range of the moving weight to the head side and the tail side of the hollow region, and a head side of the shaft. The movable weight is provided with a magnet that is arranged in the vicinity of the stopper member and exerts a magnetic force on the movable weight in a non-contact state, and the movable weight has a rod-shaped main body portion having a predetermined length in the axial direction and an axis. The magnet is provided with an insertion hole formed in parallel with the magnet, and is inserted into the shaft through the insertion hole, and the magnet faces the side portion of the movable weight with a predetermined gap. The facing surface is configured to have a facing region having a length equal to or less than the axial length dimension of the moving weight, and the moving weight has a head. When moved to the stopper member on the side, the center of the facing surface is arranged so as to be at the center of the movable weight in the axial direction or at a position biased toward the head side. And.

According to the invention of the above configuration, the movable weight is formed of a rod-shaped main body portion, and an insertion hole formed in parallel with the axial direction thereof is inserted into the shaft so as to be movable along the shaft. Since the movable weight is provided, the axis of the movable weight is parallel to the axis of the shaft, and when the movable weight approaches the facing surface of the magnet, the side portion thereof is pulled by the magnetic force of the magnet to stop the movement. .. Here, by making the facing surface of the magnet equal to or less than the axial length dimension of the movable weight, particularly by making the facing surface extremely smaller than the moving weight, the magnet The (opposing surface) attempts to adjust the relative positional relationship between the two so that they are magnetized at the center of the movable weight in the axial direction (so that a stable magnetic force without bias is applied). At this time, the present invention is installed so that the center position of the facing surface of the magnet is the center position in the axial direction of the movable weight that has moved to the head side or a position that is biased toward the head side. Therefore, the movable weight is stable at the position where the center in the axial direction is closest to the center of the contact surface of the magnet, so that the position of the magnet can be guided to the head side. This becomes remarkable when the center position of the facing surface of the magnet is biased toward the head direction. Therefore, it can be stabilized in a state where the movable weight has moved to the stopper member (a state in which the tip surface of the weight is in contact with the stopper member).

In the invention having the above configuration, the main body of the mobile weight is formed in a cylindrical shape, and the facing surface is formed in a circular shape or an annular shape. , The circular or annular center line of the facing surface, and the axis of the shaft may be configured to be arranged on the same virtual plane.

In the case of the above configuration, the generatrix of the main body and the center line of the facing surface are the longest distance at a position where the main body of the cylindrical movable weight and the facing surface of the circular or annular magnet are close to each other. Since the shaft is inserted into the insertion hole of the movable weight, the reaction force of the shaft can be maximized. That is, in order to stop the movement of the moving weight, the attractive force of the magnet to the weight and the reaction force of the shaft are used. Therefore, the movement of the moving magnet is caused by the maximum action of these forces. It will be stable in the stopped state.

In the case of the invention having the above configuration, the insertion hole for the movable weight is preferably provided on the center line of the cylindrical main body portion, and the gap between the side portion of the main body portion and the facing surface is preferably uniform. .. By providing the insertion hole on the center line of the cylindrical shape, even if the movable weight of the cylindrical shape rotates around the shaft, the above relationship continues, and the side portion of the main body and the facing surface are aligned with each other. Since the gap between the magnets is uniform, the magnetic force of the magnet does not act on the mobile weight in different states.

Further, the facing surface is preferably formed of a portion serving as a magnetic pole, and is preferably formed of a mixture of tungsten and iron in order to obtain a mobile weight having a high specific gravity due to a magnetic material.

Further, in the invention of each of the above configurations, a fixed weight that does not move in the hollow region is further provided, and the regulation region or the shaft is provided in a range from the vicinity of the head to the vicinity of the tail of the lure body, and the movement is described. The mold weight is movable toward the head side of the center of the lure body in the longitudinal direction, and when the mobile weight moves to the restricted area or the head end of the shaft, the movable weight is used. Due to the weight of both of the fixed weights, the position of the center of gravity of the entire lure body can be arranged closer to the head than the center.

According to the above configuration, the fixed weight and the movable weight exist inside the lure body, and the position of the center of gravity of the entire lure can be adjusted by the weight balance between the two. The reason for moving the movable weight inside the lure body is, as described above, to stabilize the flight attitude during casting and to adjust the position of the center of gravity during reeling. Therefore, the existence of the fixed weight makes it possible to change the position of the center of gravity of the entire lure body, for example, to distinguish between the head and the tail of the lure body. When the center of gravity of the lure body is closer to the tail, the posture during casting is stabilized, and when the center of gravity is closer to the head, the posture during reeling can be adjusted.

In the invention having the above configuration, the fixed weight may be provided at least on the tail side of the lure body in the longitudinal direction. The number of fixed weights is not limited to one, and a plurality of fixed weights may be provided, and it is preferable that at least one of them is on the tail side of the center and the entire center of gravity of the fixed weight is closer to the tail. This is because the weight balance closer to the head can be changed by moving the mobile weight.

According to the present invention, since the weight composed of the magnetic material and the magnet for magnetizing the weight are maintained in a non-contact state, the concern of damage due to collision is eliminated, and therefore, the weight is used many times. Will be able to withstand. Further, in the case of the configuration provided with the fixed weight, even if the movable weight does not function, the weight balance by the fixed weight, at least the balance in the vertical direction, is maintained, and continuous use is performed. Is possible.

Furthermore, by making the size of the magnet smaller than that of the mobile weight and setting the center position of the magnet to the head side rather than the center when the mobile weight stops on the head side, the mobile weight can be headed. Since it is guided to move to the part mold, the movement of the mobile weight due to the vibration of the lure (sway during reeling) in water is suppressed, and the stopper member and the mobile weight are separated from each other. It is also possible to prevent the generation of collision noise caused by repeated contact.

<Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the entire lure according to the present invention. Both FIGS. 1 (a) and 1 (b) are vertical cross sections along the center line, and both show the same state except that the positions of the movable weights are different. As shown in this figure, the lure 1 of the present embodiment includes a lure body 2, a shaft 3 extending in a direction extending from a head 21 to a tail 22 in a hollow region 20 formed therein, and a lure body 2. It includes a movable weight 4 inserted into the shaft 3 and a magnet 5 capable of applying a magnetic force to the movable weight 4 in a non-contact state.

The lure 1 illustrated in the embodiment is a ripple lure, a plurality of eyelets 11, 12, and 13 are attached to the lure body 2, and the eyelets 11 provided on the side of the head 21 are used as line eyes. The eyelets 12 and 13 used and provided at the positions of the tail 22 and the center 23 are hook eyes to which the hooks 14 and 15 are attached, respectively.

In addition, the lure body 2 is generally made of an injection-molded plastic material, and the symmetrically formed 1/2 portions are individually manufactured and bonded at the center to form an integral lure. It has the shape of the main body 2. Therefore, in the figure, the hatched portion representing the cross section of the lure main body 2 is the end face of the cut portion in the entire lure main body 2, but the half portion formed symmetrically is the surface to be joined. .. Therefore, in the hollow region 20, a portion in which a cavity (concave portion) is formed at the time of molding is used, and the hollow region 20 is formed as a space inside by joining. Further, each element installed inside is positioned by joining after being installed in the cavity.

The shaft 3 is composed of a linear rod-shaped member (wire rod), and both ends thereof are supported by support portions 6 and 7 formed in a hollow region 20 of the lure body 2. The support portions 6 and 7 include terminal support portions 61 and 71 surrounding both ends of the shaft 3 and wall portions 62 and 72 provided closer to the center of the shaft 3 than the terminal support portions 61 and 71. .. By surrounding both ends of the shaft 3, the end support portions 61 and 71 restrict the movement in the front-rear direction (direction from the head 21 to the tail 22) and in the direction orthogonal to the front-rear direction. Further, the wall portions 62 and 72 are provided in an appropriate area and receive the contact of the movable weight 4. That is, the end face 41 on the front side (head side of the lure body) of the movable weight abuts on one wall portion 62, and the other end face (rear end face) 42 abuts on the other wall portion 72. The movement will be restricted. Therefore, the movable weight 4 functions as a stopper member for determining the moving range.

The shaft 3 is preferably made of a non-magnetic material. This is because, as will be described later, the mobile weight 4 through which the shaft 3 is inserted is composed of a magnetic material, which is affected by the magnetic force of the magnet 5. Therefore, when the magnetic material is magnetized, the shaft 3 and This is because there is a possibility that the mobile weight 4 and the mobile weight 4 are magnetized at the contact portion. Stainless steel or the like can be used as the non-magnetic material. A non-magnetic material is preferable, but a magnetic material that does not exhibit strong magnetism can be used even if it exhibits a slight magnetism. In that sense, a non-magnetic material means a material that is not a ferromagnetic material.

Further, since the shaft 3 regulates the moving direction and the moving range of the movable weight 4 as described later, the shaft 3 is provided linearly in a predetermined range. In this sense, the range in which the shaft 3 is provided is the regulated area. Therefore, when a regulated region is formed by another method instead of the shaft 3, three or more linear rail-shaped members are arranged, and movable weights are provided at three or more locations at the tips of the rail-shaped members. It may be configured to be in sliding contact.

The movable weight 4 is provided in the shape of a rod having an appropriate length, has an insertion hole on the center line thereof, and the shaft 3 is inserted (free-fitted) into the insertion hole along the shaft. It is possible to move. The state of penetration of the shaft 3 is a loose fitting state with a slight play, but the inner diameter of the insertion hole is slightly larger than the outer diameter of the shaft 3 so as not to cause extreme play. It has become.

Further, as will be described later, the movable weight 4 is restricted from moving along the shaft 3 by the action of the magnetic force of the magnet 5. In order to obtain the effect of magnetic force, the mobile weight 4 is made of a magnetic material. At this time, in order for the mobile weight 4 to function as a weight, it is preferable to obtain an appropriate weight, particularly a large weight with a small volume as a high specific gravity. Therefore, in this embodiment, a mixture of tungsten and iron is used. Since tungsten is not a magnetic material, it is made into a magnetic material as a whole by mixing iron. The mixture of tungsten and iron can be produced, for example, by a powder metallurgy method. Not limited to tungsten, a mixture of a metal having a high specific gravity and another metal that is a magnetic material (not necessarily iron) may be used. In the case of producing a mixture by the powder metallurgy method, since the iron component is also present in a wide range on the surface of the mobile weight 4, it can act as a magnetic substance even if the mixing ratio of iron is small.

The magnet 5 is provided in the vicinity of the support portion 6 provided on the side of the head 21, that is, in the vicinity of the head side stopper member (wall portion) 62, and within the range in which the movable weight 4 can move. Has been done. Further, even when the mobile weight 4 is close to the magnet 5, the mobile weight 4 is arranged with a gap H so as not to come into contact with the magnet 5. Further, as will be described in detail later, the magnet 5 is held by a magnet holding portion 63 integrally provided with a support portion 6 that supports the tip of the shaft 3 on the head 21 side, and is a part of the magnet 5 (opposed). The surface) 51 is arranged so as to face the mobile weight 4.

In the figure, the magnet 5 is illustrated above the mobile weight 4 (back side), but if it is in a non-contact state around the mobile weight 4, it is below (abdominal side). It may be sideways. However, when it is provided on the side, it may be necessary to adjust the weight balance between the left and right, such as providing one magnet on each of the left and right sides in the same manner (for the target). Further, since the magnet 5 exerts a magnetic force on the movable weight 4 in a non-contact state, a type having a large magnetic force is preferable. For example, neodymium magnets can be used.

Here, the magnet 5 used in the present embodiment will be described in detail, and the relationship with the mobile weight 4 will be described. FIG. 2 shows the relationship between the mobile weight 4 and the magnet 5. Note that FIG. 2A shows a state in which both are viewed from each other, FIG. 2B shows a cross section taken along the line IIB-IIB, and FIG. 2C shows a cross section taken along the line IIC-IIC. As shown in FIG. 2A, the mobile weight 4 has a columnar shape as a whole. On the other hand, the magnet 5 has a circular cross-sectional shape as a whole and has a disk shape. The disk-shaped magnet 5 has circular surfaces on both the upper and lower sides 51 and 52, and the lower surface 51 is arranged so as to face the movable weight 4, and the lower surface 51 serves as the facing surface 51. Is.

In the present embodiment, the generatrix 40 formed at the uppermost position of the cylindrical movable weight 4 and the center line 50 of the disk-shaped magnet 5 are parallel to each other. The center line 50 of 5 is located directly above the bus 40 of the mobile weight 4. Since the bus 40 is parallel to the axis 30 of the shaft 3, all of the bus 40 including the axis of the shaft 3 are parallel. Therefore, in other words, the arrangement state of the magnet 5 is that the axis 30 of the shaft 3, the uppermost bus 40 of the movable weight 4, and the center line 50 of the magnet 5 are on the same virtual plane (particularly in the drawing). It is in a state of being arranged on a vertical plane).

In the cross section of this state by the IIB-IIB line, as shown in FIG. 2B, the left and right sides are symmetrical with the vertical center line as the boundary. As is clear from this figure, the uppermost position (upper end of the circular cross section) of the cylindrical movable weight 4 and the center (center point) of the facing surface 51 of the magnet 5 are closest to each other. .. Then, by making the facing surface 51 (and the upper surface 52) the magnetic pole of either the N pole or the S pole, strong magnetism can be generated. As a result, the mobile weight 4 is strongly affected by the magnetic force even when it is not in contact with the magnet 5, and the magnetic force acts strongly especially at the closest position, so that the mobile weight 4 moves. Can be restricted.

Further, as shown in FIG. 2C, assuming a state in which the mobile weight 4 does not descend due to its own weight and does not rise due to the magnetic force, in the cross section taken along the IIC-IIC line, the axis 30 of the shaft 3 The axis of the movable weight 4 is the same, and the uppermost bus (upper end edge in the end face of the cut portion in the figure) 40 is located directly above the axis 30 of the shaft 3, and the center line of the magnet 5 (cut in the figure). The end face) 50 is also located directly above. In this state, the gap H formed between the uppermost bus 40 of the mobile weight 4 and the facing surface 51 of the magnet 5 is the same gap H in the radial direction of the magnet 5, so that the facing surface 51 is The entire range facing the mobile weight 4 also exerts a magnetic force.

As described above, since the movable weight 4 and the magnet 5 are provided symmetrically, they can be positioned symmetrically even inside the lure body 2 as shown in FIG. 2D. Since the lure body 2 is constructed by laminating 1/2 portions 2a and 2b, if the shaft 3 and the magnet 5 are arranged (fixed) around this laminating position, a symmetrical lure body 2 can be produced. At the same time, the configuration can be symmetrical inside.

At this time, as shown in FIG. 2D, since the disk-shaped magnet 5 minimizes the gap with the movable weight 4 only in the center, the action of the magnetic force in the vicinity of both ends in the left-right direction is exerted. Since it is small, when the left and right edges are held by the holding portions 63 (63a, 63b) from both sides together with the 1/2 portion of the lure body 2, the magnet 5 is held upward and the magnetic force acts. , The magnet 5 is maintained so as not to move toward the movable weight 4.

The position where the magnet 5 should be arranged is directly above the shaft 3 and the movable weight 4, but when it is arranged symmetrically, it may be located directly below. In this case, the facing surface 51 is arranged upward. Further, focusing only on the relationship between the movable weight 4 and the magnet 5, it may be arranged in either the left-right direction. At this time, in order to make the weight symmetrical, one each is placed symmetrically on both the left and right sides. Individuals may be arranged.

Next, the arrangement state of the magnet 5 in the axial direction of the shaft 3 (longitudinal direction of the lure body) will be described. Here, it is assumed that each element as illustrated in FIG. 2 is used, and the case where the magnet 5 is arranged directly above the movable weight 4 is illustrated. As shown in FIG. 3A, when the facing surface 51 of the disk-shaped magnet 5 is a magnetic pole (for example, N pole), the magnetic field generated by the magnet 5 acts evenly in a loop shape around the disk shape. To do.

When the moving weight 4 which is a magnetic material moves to the region where the magnetic field (magnetic force) acts, the moving weight 4 is adsorbed by the action of the magnetic force. At this time, only a part of the mobile weight 4 is adsorbed and the movement is not restricted, but the adsorbing force causes the mobile weight 4 to be more strongly adsorbed. This is because it is guided to a position where a stronger magnetic field is generated, and also because it acts so that the balance of the magnetic fields becomes even. As a result, as shown in FIG. 3B, the longitudinal center line Y of the mobile weight 4 coincides with the center line of the magnet 5. Then, in this state, the balance of the magnetic field becomes uniform, and the magnetic force acts stably.

It should be noted that such a state of equilibrium / imbalance of the balance of the magnetic field is the length of the bus of the mobile weight 4 (the upper end edge at the end face of the cut portion in the drawing), that is, the length dimension in the axial direction and the facing surface 51. The length dimension of the diameter (the diameter direction in the center of the longitudinal direction is the opposite region) may be the same, but it will appear remarkably when both dimensions are significantly different. Therefore, in the present embodiment, the dimension of the facing region (diameter) of the facing surface 51 is 1/2 of the length dimension of the bus of the movable weight 4.

In this way, at least in order to stop the mobile weight 4 in the stable state as described above, the end surface 41 on the front side (head side of the lure body) is in the state where the mobile weight 4 is stopped as described above. The head side stopper member (wall portion) 62 will be provided so that they can come into contact with each other. This state is shown in FIG. 3 (c). The reason for providing the head side stopper member 62 at this position is, firstly, to make the weight balance of the entire lure uniform by stopping the stop position of the movable weight 4 at a specific position. Secondly, it is for preventing the movable weight 4 and the stopper member 62 from colliding with each other due to the movable weight 4 swaying finely due to the vibration of the lure in use or the like.

As described above, when the purpose is to prevent the movable weight 4 and the stopper member 62 from colliding with each other, as shown in FIG. 3D, the longitudinal center line Y1 of the movable weight 4 is set. It is preferable to provide the head side stopper member 62 at a position where the movement of the movable weight 4 is stopped immediately before reaching the center line Y2 of the magnet 5. This is because, as described above, in order to evenly balance the magnetic field by the magnet 5, a magnetic force that moves the movable weight 4 forward (toward the head side) acts, and this magnetic force acts. By the action of, the movable weight 4 can be brought into a state of being pressed against the head side stopper member 62. Due to the action of such a pressing force, even when the lure vibrates when the lure is used, the mobile weight 4 does not easily separate from the head side stopper member 62, and a collision occurs. It can be very small.

As described above, in order to press the movable weight 4 against the head stopper member 62 by the magnetic force of the magnet 5, the center lines Y1 and Y2 of both may be biased and arranged. When the diameter of 5 is 1/2 of the length of the bus of the mobile weight 4, the side surface of the magnet 5 on the head side can be headed by arranging the magnet 5 at a position deviated by 1/4 of the bus. It can be provided so as to coincide with the surface of the side stopper member 62.

<Operating mode>
Next, the operation mode of this embodiment will be described. FIG. 4 shows a state in which the mobile weight 4 moves. Note that (a) in FIG. 4 shows a state in which the mobile weight 4 is located on the tail side, (c) is a state in which it is located on the head side, and (b) is a state in which it is located in the middle. It shows. Further, in the example shown in FIG. 4, a state in which the insertion hole 43 of the movable weight 4 is loosely fitted to the shaft 3 is shown, and the state of the gap between the two at this time is exaggerated so as to be easy to understand in the drawing. Is shown.

As shown in FIGS. 4A and 4B, when the mobile weight 4 is not stopped by the magnet 5, the mobile weight 4 is movable along the shaft 3. Since the shaft 3 is linear and the insertion hole 43 of the movable weight 4 having a columnar shape is provided linearly on the center line, the shaft 3 can be freely moved along the linear shaft 3. Moreover, the rotation around the axis is free, but the other degrees of freedom are limited.

By the way, since the insertion hole 43 of the movable weight 4 is loosely fitted to the shaft 3, when the axis of the shaft 3 is oriented sideways (horizontally) as shown in the figure, the movable weight 4 is slightly reduced by its own weight. However, it descends and hangs down, and the upper portion of the insertion hole of the movable weight 4 is in sliding contact with the upper surface of the shaft 3, and both of them move while sliding. Since the sliding contact portion at this time is extremely small, it can move smoothly without being greatly affected by resistance (friction resistance). Further, since the insertion hole 43 is provided on the center line of the movable weight 4, the descending (hanging) direction is not specified. Although it is possible to make the hanging state a constant direction by intentionally deviating from the center line, the gap with the magnet 5 when rotating about the axis may become non-uniform. Therefore, when the movable weight 4 has a columnar shape, it is preferable to provide the insertion hole 43 on the center line.

As described above, in the range where the magnetic force of the magnet 5 does not act, the movable weight 4 can move along the axis of the shaft 3, and when the movement reaches the tip on the head side, the magnetic force of the magnet 5 causes the movement. It will be adsorbed. As shown in FIG. 4C, when the magnetic force of the magnet 5 acts, the mobile weight 4 is attracted until it reaches the center of the magnet 5 in the longitudinal direction as described above. The magnet 5 provided in the vicinity of the head-side stopper member 62 causes the movable weight 4 to be attracted to a state in which the front end surface 41 thereof is in contact with the head-side stopper member 62.

At this time, the movable weight 4 rises slightly within the range of play between the shaft 3 and the insertion hole 43 due to the attraction by the magnetic force, and the gap between the movable weight 4 and the magnet 5 becomes closer to each other. Due to this approach, the magnetic force of the magnet 5 acts even more strongly, so that the movement of the mobile weight 4 is greatly restricted.

Since the mobile weight 4 is in a state of not being in contact with the magnet 5 (non-contact), the two do not collide with each other even when a large magnetic force is applied, and therefore the magnet 5 is damaged. Never. Further, it becomes easier to separate (separate) the state as compared with the state of being in contact with magnetism. Therefore, the movable weight 4 does not easily move to the tail side by simply setting the shaft 3 downward and the shaft 3 in the vertical direction, but a light impact is applied in such a vertical state of the shaft 3. As a result, the mobile weight 4 can be dropped toward the tail side by its own weight.

<Usage mode>
When actually using the lure 1, as shown in FIG. 5, for example, by suspending the lure 1 by a line 16 connected to the eyelet 11, the shaft 3 inside the lure body 2 faces downward on the tail 22 side. It is almost vertical. Therefore, by lightly impacting the lure body 2 or applying centrifugal force by the casting operation, the mobile weight 4 moves to the tail 22 side by its own weight or centrifugal force (FIG. 5 (FIG. 5). a) See).

Then, by reeling the lure 1 that has landed on the water by casting, the lure 1 stabilizes its posture in water, and the head 21 is in a position lower than the tail 22 due to the action of the lip 17. Due to such a posture in which the head 21 is in the lower position, the shaft 3 inside the lure body 2 is tilted according to the posture, and the movable weight 4 is moved to the side of the head 21 by its own weight along the tilt. It will be. Then, when it reaches the region where the magnetic force of the magnet 5 acts, it is attracted by the magnet 5 and stops in a state of reaching (contacting) the head side stopper member 62 (see FIG. 5B). In this stopped state, the position of the mobile weight 4 is stable, the overall weight balance of the lure body 2 is assumed, and the lure is made to swim like a small fish to induce the target fish. Can be done.

<Modification example>
The embodiment of the present invention is as described above, but a modified example of the above embodiment will be described. As a modification, as shown in FIG. 6, fixed weights 8 and 9 are installed inside the lure body 2. FIG. 6A shows a configuration in which a first fixed weight 8 is provided on the abdomen of the lure body 2. By installing the fixed weight 8 on the abdomen, the abdomen becomes heavier than the back, so that the posture of the lure 1 in water makes it easy for the abdomen to be lower and the back to be higher. Further, as an overall weight balance, since the fixed weight 8 is present substantially in the center of the lure body 2, the mobile weight 4 moves closer to the head 21 than the fixed weight 8. It tends to be the center of gravity of. Further, since the resistance received by the lip 17 due to reeling is guided downward of the head centering on the fixed weight 8, the shaft 3 can be tilted quickly.

Further, as another modification, as shown in FIG. 6B, a second fixed weight 9 is additionally provided in the vicinity of the head 21. This is an embodiment in which the weight of the head 21 is increased in relation to the weight balance with the first fixed weight 8 provided on the abdomen. Since the fixed weight 9 is present in the vicinity of the head 21 in advance, the weight balance is moved forward (toward the head), so that the shaft 3 is quickly tilted at the time of landing and the movable weight 4 is moved. Can be facilitated.

The installation / non-installation or the position or number of the fixed weights 8 and 9 may be changed according to the type of each lure 1. For example, in the case of a lipless plug, the lure 1 in water operates so as to vibrate the front (head side) and the rear (tail side) of the lure 1 in the front-rear direction (longitudinal direction) with the center as the axis. , A fixed weight 8 may be provided on the abdomen, and the stop position of the mobile weight 4 may be selected to be closer to the center. On the other hand, in the case of a ripple lure, the degree to which the head 21 is deepened or vibrates differs depending on the size of the lip (water resistance at the time of reeling). A fixed weight 9 can be provided in the vicinity for adjustment.

The embodiments and modifications of the present invention are as described above, but the present invention is not intended to be limited to these embodiments and the like. That is, it is possible to modify the elements shown in the above-described embodiments and modifications, or to add other elements.

For example, in the above-described embodiment and modification, the regulated region is formed by the shaft 3, but the regulated region may be formed by another configuration. As described above, for example, the regulated region may be formed by sliding the circular cross section of the movable weight 4 at three or more points with a rail-shaped member. When the regulated region is composed of rail-shaped members, the movable weight 4 can be formed not only in a columnar shape but also in a spherical shape. Further, even when the shaft 3 is used, the movable weight 4 does not have to be cylindrical. An insertion hole that passes through the center of the spherical weight may be formed. Further, even if it is not spherical, it can be used in the same manner as a columnar or spherical shape as long as it has a rotating body shape with a uniaxial central axis.

Further, the shape of the magnet 5 is illustrated as a disk shape, but the shape of the magnet 5 is questionable as long as it can apply a magnetic force to the mobile weight 4 in a non-contact state. is not it. In particular, in the above embodiment, the thickness is shown to be relatively thin in the drawing, because the magnet 5 does not have a large weight in consideration of the weight balance due to other weights, the movable weight 4, and the like. If a predetermined weight is required at the position to be installed, the weight balance may be adjusted by using a thick magnet 5.

In an extreme case, the mobile weight 4 can be used as long as it is a lump of heavy objects. Then, when the gap with the magnet 5 changes by rotating around the axis of the shaft 3, it is also possible to use two parallel shafts. In this case, the area where the two shafts are provided can be the regulated area.
