Description

The present invention relates to a lure, and relates to a lure having a weight that can move along a shaft provided in the space of the lure body.

So far, the applicant of the present application has developed a mechanism in which a shaft is arranged in the space of the lure body and the weight is moved along the shaft. In this mechanism, in order to hold the weight near the center of the lure, a magnet piece is provided at the tip of the shaft, and a weight obtained by mixing a material that can be magnetized by a magnet with a material having a high specific density is used (Patent Document). 1).

Japanese Unexamined Patent Publication No. 2001-299150

In the invention disclosed in Patent Document 1 described above, the shaft is arranged in a range from the vicinity of the tail of the lure body to the vicinity of the center, and the weight can move between them. Therefore, when casting, the weight is placed on the tail side. The center of gravity can be biased by moving to, the attitude during flight can be stabilized, and after landing, the weight moves according to the attitude of the lure body, and it is magnetized by moving to the magnet piece. , The center of gravity could be moved near the center. By moving the center of gravity to the vicinity of the center, it was assumed that the lure's posture in the water would be stable during retrieval (releasing), and it would be possible to realize a sharp movement.

However, in the above invention, a magnet piece for holding the weight is provided at the front end of the shaft, and the weight is magnetized by the magnet piece, and the front surface of the weight is in surface contact with the magnet piece. It was configured to be magnetized with. This is to ensure the holding of the weight by magnetism, but when the magnetism is strong, it may not be easy to release the weight from the magnetized state. In order to solve this, it can be assumed that the mixing ratio of the material having a high specific density that is not magnetized is increased, but it is not easy to adjust the mixing ratio in order to exert an appropriate magnetizing force.

In addition, the method of fixing the weight so far has been magnetic attachment using a magnet, but the weight of the magnet itself acts as a kind of weight, and the weight balance at the time of casting and the weight balance in water The position and size (weight) of the magnet had to be determined in consideration of both of the above, and the design for that purpose was not easy.

The present invention has been made in view of the above points, and an object of the present invention is to provide a lure having a structure in which a weight can be fixed at a desired position without using a magnet.

Therefore, the present invention is a lure in which a weight that moves back and forth from the vicinity of the tail of the lure body toward the head is provided in a space provided inside the lure body, and is near the tail of the lure body. A moving area of a weight formed in an appropriate range from the lure, a weight arranged so as to be able to move forward and backward in this moving area, and the weight moving forward from the vicinity of the tail of the lure body toward the head to a desired stop position. It is provided with a stopper that can temporarily suppress the retreat of the weight in the tail direction when moving, and the stopper is provided so as to appear and disappear in the space area through which the weight passes when moving, and the tail of the weight. It is characterized by including a contact portion capable of contacting a part of the side surface and an urging means capable of urging the contact portion in a direction resisting the retreat of the weight.

According to the above configuration, since the contact portion of the stopper is provided so as to be able to appear and disappear in the space region through which the weight passes when moving, the movement of the weight is suppressed and the weight sinks in the state of protruding into the space region. It becomes possible to move in the state of doing. Further, since the urging means urges the contact portion in a direction that opposes the retreat of the weight, the weight advances toward the head of the lure body, and the desired stopping position (lure body). When it reaches (near the center of the center), the retreat can be suppressed by revealing a state in which the abutting portion abuts on the surface on the tail side of the weight. The space area through which the weight passes when moving is a space different from the moving area of the weight, which is a space formed by the locus when the weight actually moves, and the range of the stopping position from the vicinity of the tail is defined. It means the area through which the moving weight completely passes. In other words, it means a region formed in the range from the head-side surface in the state of being stopped near the tail to the tail-side surface in the state of being stopped at the stop position in the movement region of the weight. Further, the possibility of appearing in this space region includes a case where it can appear and disappear by being actively operated, and a case where it appears and disappears as a result of being passively operated by a weight.

In the case of the above configuration, in order to allow the abutting portion to appear and disappear in the space region, the abutting portion can be configured to rotate about a specific rotation axis. In this case. The urging force in the direction against the retreat of the weight by the urging means may apply the urging force in the rotational direction. In addition, as a configuration that can appear and disappear, there is a configuration that utilizes an elastic force such as a spring, and a configuration that simultaneously applies an urging force and utilizes an elastic force such as a spring may be used. Furthermore, there may also be a configuration that allows haunting and urging by both rotation and springs and the like.

In the invention of the above configuration, it is assumed that the stopper is composed of a torsion spring provided in a space portion of the lure body, and the contact portion is formed by the tip of an arm on the load point side of the torsion spring. be able to. According to such a configuration, the load point side arm of the torsion spring can give an urging force against the retreat of the weight while making it possible to appear and disappear in the space area through which the weight passes by the elastic force of the torsion spring. can.

Specifically, the torsion spring is arranged in a state where the coil portion is supported by a support portion of an axis orthogonal to the advancing / retreating direction of the weight, and the contact portion is arranged parallel to the axis of the support portion. It can be provided in a linear shape.

According to the above configuration, by supporting the coil portion of the torsion spring by the support portion, it is possible to generate urging in the rotational direction with the support portion as an axis. Further, since the axis of the support portion is orthogonal to the advancing / retreating direction of the weight, the urging force due to the rotation of the torsion spring is in the direction along the moving direction of the weight. Therefore, the torsion spring can act on the appearance of the weight in the space region through which the weight passes and the application of the urging force for the contact portion to suppress the retreat of the weight.

In the case of the above configuration, the torsion spring has a free angle as a inferior angle, and when the abutting portion abuts on the tail side surface of the weight due to the movement of the weight from the stopping position in the retracting direction, the load point. It may be arranged so as to load the side arm in the twisting direction.

According to the above configuration, the free angle of the torsion spring (the angle formed by the fixed point side arm and the load point side arm) is set to be inferior, and the contact portion receives the contact with the surface on the tail side of the weight and loads in the twisting direction. Therefore, the spring pressure of the torsion spring can be applied when suppressing the retreat of the weight. Further, since the contact portion is provided at the tip of the load point side arm, the contact portion is separated from the weight by being displaced by the load on the arm, and the contact portion comes into contact with the tail side surface of the weight. When the state is released, the weight will be able to retract. The load point side arm means an arm on the side that becomes the load point when a load acts on the torsion spring, and the other arm is fixed to generate a torsional moment. This fixed side arm is called a fixed point side arm.

In the invention having the above configuration, the fixed point side arm is supported in a state where the coil portion has a play that allows the coil portion to rotate within a predetermined range around the axis of the support portion, and the contact portion is the weight. Based on the state of contact with the surface on the tail side of the lure, the corresponding contact portion can be made rotatable toward the head side of the lure body.

According to such a configuration, the fixed point side arm should be originally fixed because it causes a torsional moment in the torsion spring, but the fixed state is around the axis of the support shaft by an appropriate amount of play. Since it is rotatable in the (circumferential direction), the state of contact by the contact part when the weight moves forward toward the head side and the state of contact when the weight moves backward toward the tail side. A difference can be made between and. That is, since the contact portion can be rotated toward the head side based on the state where the contact portion is in contact with the tail side surface of the weight, when the weight advances toward the head side, the contact portion is the weight. Even if it comes into contact with a part of the head side surface, the entire torsion spring can rotate and move the weight smoothly, while when the weight retracts, it comes into contact with the tail side surface. Since the rotation is stopped in this state, the urging by the torsion spring acts directly.

In each of the above configurations, in the configuration using the torsion spring, the torsion spring is composed of a double torsion spring, and the contact portion is the tip of two load point side arms provided on the two coil portions. Can be composed of a continuous portion in which is continuous.

In the case of the above configuration, when the weight is moved in the center in the plan view of the lure body, the coil portions can be arranged on both sides thereof, and the urging state when suppressing the retreat of the weight can be stabilized. can. In particular, when the fixed state of the fixed point side arm has play, both the rotation of the coil portion (substantially the support shaft) around the axis and the twist due to the load on the load point side arm. Even when receiving, the fixed point side arm is also supported at two places, so that the posture of the torsion spring can be stabilized.

In the invention of each of the above configurations, a shaft having an axis in the advancing / retreating direction of the weight is provided in the moving region of the weight, and the weight is formed in a columnar shape and is provided with a through hole parallel to the generatrix direction. The shaft may be inserted into the through hole to allow the weight to move forward and backward along the shaft.

According to the above configuration, the shaft provided in the moving region has an axis in the advancing / retreating direction of the weight, and the weight is formed into a columnar shape by inserting the shaft into a through hole parallel to the generatrix direction. Since it is movable, the weight can move while stabilizing its posture while being inserted through the shaft. In particular, even in a state where the urging force is applied by the stopper (contact portion), since the shaft is inserted through the weight, it cannot move in any direction other than the direction in which it can move forward and backward, so that the urging force by the stopper is sufficiently applied. Can act.

Further, when the shaft is not used, the moving region of the weight is formed by dividing the space inside the lure body by a rail member that enables the weight to roll or slide, and the weight is formed. , It may be formed by a rolling member or a sliding member that can roll or slide in the moving region.

In the case of the above configuration, since the moving area of the weight is provided separately from other spaces of the lure body by the rail member, it can freely roll or slide only in the moving area. The rail member may be in the shape of a gutter or a flat plate, and in the case of the flat plate-shaped rail member, the moving region can be divided as a whole by arranging a plurality of members. Since this rail member makes it impossible for the weight to escape from the divided moving area, it stays inside the moving area even when it is urged by the stopper (contact portion), and the urging Will receive. The rolling member may be a columnar member capable of rolling on the surface of the rail member in the advancing / retreating direction, or may be formed of a sphere having a free rolling direction. Further, the sliding member is a member that can be provided in a state where a non-rollable massive weight is partially slidably contacted with the rail member. For example, in the case of a columnar member, the sliding member moves in the axial direction. It is possible to form a sliding member by partially sliding the bus portion of the side surface thereof with the rail member.

According to the present invention, the retreat of the weight can be temporarily suppressed by the stopper provided with the contact portion that appears and disappears in the space region through which the moving weight passes, so that the weight is fixed at a desired position without using a magnet. Will be able to.

Further, when the stopper is formed by a torsion spring, it is possible to apply an urging force around the axis of the support portion that supports the coil portion, and the direction of urging by the contact portion is set to the axial direction. Therefore, it can be easily made to appear and disappear depending on the degree of rotation in the axial direction.

<Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an internal state of the lure 1 according to the embodiment of the present invention. As shown in this figure, the lure 1 has a lure body 2 and a plurality of eyelets 11, 12, and 13 attached to the lure body 2, and the eyelets 11 provided on the head 21 of the lure body 1 are used as line eyes. The eyelets 12 and 13 in the vicinity of the tail 22 and the center 23 are used as hook eyes, and hooks 14 and 15 are provided, respectively. Further, a space portion 20 is formed inside the lure main body 2.

The lure 1 of the present embodiment utilizes the space portion 20 of the lure main body 2 having the above configuration, and the space portion 20 is formed inside by the outer shape portion of the lure main body 2. Using this space portion 20, a linear shaft 3 is arranged in the front-rear direction of the lure body 2 (the direction from the vicinity of the head 21 to the vicinity of the tail 22), and the shaft 3 is inserted through the weight 4. Therefore, a moving region of the weight 4 is formed. That is, the weight 4 can move along the shaft 3, and the range in which the shaft 3 is provided is the moving region. The shaft 3 is made of a metal such as stainless steel so as to have enough strength to support the weight 4, and both ends of the shaft 3 of the lure body 2 are located near the center 23 of the lure body 2 and near the tail 22. It is supported by the front end support portion 24 and the rear end support portion 25 formed in the space portion 20.

Further, in the present embodiment, the shaft 3 is provided in a predetermined range from the vicinity of the tail portion 22 of the lure body 2 to the vicinity of the center 23, and therefore, the weight 4 is provided in the front end support portion 24 and the rear end within the range. It is movable until it comes into contact with the support portion 25. A through hole as described later is formed in the weight 4, and the shaft 3 is loosely fitted so that the weight 4 can move forward and backward. As a method of arranging the weight 4 so as to be able to move forward and backward, there may be a configuration in which the weight 4 is rolled, in addition to the configuration in which the shaft 3 is inserted through the weight 4. Other configurations in which the weight 4 is provided so as to be able to move forward and backward will be described later as a modified example, but in the present embodiment, a configuration in which the weight 4 is moved forward and backward by the weight 4 through which the shaft 3 is inserted will be described as a typical example.

In the above configuration, when the weight 4 has moved to the vicinity of the center 23 of the lure body 2, the retreat of the weight 4 (movement toward the tail 22) is temporarily suppressed. Temporarily suppressing means that when an external force that forcibly retracts the weight 4 is applied, the weight 4 can be retracted by the action, but such an external force (external force due to intentional or unavoidable force) acts. It means a state in which the weight 4 can be fastened without retracting.

Therefore, the present embodiment includes the stopper 5. The stopper 5 is composed of a torsion spring 50, the coil portion 51 of the torsion spring 50 is supported by the support portion 6, and the fixed point side arm 52 is fixed by the fixing members 7 (7a, 7b). As a result, a predetermined urging force is applied to the load point side arm 53. The support portion 6 is a rod-shaped member in which a part of the lure main body 2 is projected inside the space portion 20, and the coil portion 51 is loosely fitted into the support portion 6 to twist the coil portion 51. It is possible. Since the support portion 6 is loosely fitted, the support portion 6 can be freely rotated around the axis (circumferential direction).

A contact portion 8 is formed at the tip 54 of the load point side arm 53 of the torsion spring 50. The abutting portion 8 is a portion that abuts on the weight 4, and can abut on the tail side surface of the weight 4 when the retreat of the weight 4 is temporarily suppressed.

Here, the relationship between the weight 4 and the torsion spring 50 (particularly the contact portion 8) will be described in detail. The relationship between the two is shown in FIG. Note that FIG. 2A is a perspective view of the weight 4 with the shaft 3 inserted and the torsion spring 50, and FIG. 2B is a cross-sectional view taken along the line IIB-IIB, FIG. c) is a cross-sectional view taken along the line IIC-IIC.

As shown in FIG. 2A, the torsion spring 50 used in this embodiment is a double torsion spring. The double torsion spring 50 has similar coil portions 51a and 51b at two locations, each of which is provided with load point side arms 53a and 53b, and the tip 54 thereof is continuous by a continuous portion. The portion (tip) 54 is used as the contact portion 8. Since the double torsion spring 50 is installed at a predetermined position, the coil portions 51a and 51b can be loosely inserted by a single support portion 6. Further, the fixed point side arms 52a and 52b are in a state of protruding individually from the two coil portions 51a and 51b, and the two fixed point side arms 52a and 52b can also be fixed by the same fixing member 7. can. The support portion 6 and the fixing member 7 may be provided individually, but in that case, the support portion 6 and the fixing member 7 may be provided so as to project from the left and right sides of the lure body 2.

By the way, as shown in FIGS. 2 (b) and 2 (c), the weight 4 is formed in a columnar shape (the figure is a columnar shape), and a straight through hole 40 is formed along the central axis (parallel to the generatrix direction). It has been drilled. Further, since the shaft 3 is provided in a straight line, the relative relationship between the weight 4 and the shaft 3 is always maintained in the same state except for the change in the position in the longitudinal direction due to the movement. The Rukoto. In other words, as long as it moves along the shaft 3, the contour of the weight 4 relative to the center of the shaft 3 is the same (in the case of a columnar shape, it is a concentric circle). However, since the through holes 40 allow the shaft 3 to be loosely inserted, they are not completely the same (concentric circles) (see FIG. 2C), but this can be recognized as an error range.

Further, the tip 54 (contact portion 8) of the load point side arm 53 is arranged linearly in the direction Y perpendicular to the axial direction (the same as the advancing / retreating direction of the weight 4) X of the shaft 3. .. The axial direction Y of the tip 54 (contact portion 8) is the same (parallel) as the axial direction Y of the support portion 6 that supports the coil portions 51a and 51b. By making the direction Y of the tip 54 (contact portion 8) orthogonal to the axial direction X of the shaft 3 in this way, the tip 54 (contact portion 8) is appropriate with respect to the surfaces 41 and 42 of the weight 4. It can be brought into contact with a length.

The tip 54 (contact portion 8) is displaced in the circumferential direction of the coil portions 51a and 51b due to the twisting action of the torsion spring 50 (twisting action of the coil portions 51a and 51b), and the surface 41 of the weight 4 In addition to 42, the torsion spring can also come into contact with the side surface 43 due to the urging force generated by receiving the torsional moment.

Then, as described above, the contact portion 8 formed by the tip 54 of the torsion spring 50 suppresses the movement of the weight 4, so that the contact portion 8 can appear and disappear in the space region through which the weight 4 passes during movement. It is provided. The state of appearance in this spatial area is shown in FIG.

In FIG. 3, the shaded area is the space area A described above. It means a region that can be completely passed through the entire locus when the weight 4 moves within a predetermined range (range from the base end to the end end). The meaning that the abutting portion 8 is arranged so as to appear and disappear in the passing space region (hereinafter, also referred to as a passing space region) A does not mean that the abutting portion 8 actively operates and appears and disappears. It shows a state in which the weight 4 is passively submerged by an external force received by the movement of the weight 4 from the state of being arranged in the space area A. That is, with respect to the contact portion 8, when the position arranged inside the passage space region A is used as a reference, the position can be displaced by an external force, and the position is displaced, the displacement is resisted. By applying an urging force, it is possible to appear and disappear in the passage space area A.

For example, as shown in FIG. 3A, the load point side arm 53 of the torsion spring 50 appropriately extends from the coil portion 51 and reaches the inside of the passage space region A at the tip 54 (contact portion 8). It is configured to be made to. The fixed point side arm 52 is not completely fixed, and when it is fixed with play, it can rotate in the circumferential direction of the coil portion 51 within the range of the play. Even in such a case, the tip 54 of the load point side arm 53 is provided so as to be located inside the passage space region A. This is because when the weight 4 passes, it comes into contact with any part of the weight 4 and receives an external force.

Then, as shown in FIGS. 3 (b) and 3 (c), the tip 54 of the load point side arm 53 is outside the passage space region A by being twisted within an allowable range by the twisting action of the coil portion 51. It will be displaced in the direction. In such a state of displacement, the weight 4 is in a state where it can move (pass). However, in the state of this displacement, the bias in the direction against the displacement is generated.

On the other hand, as shown in FIG. 3A, in a state where the tip 54 of the load point side arm 53 is located inside the passage space region A, if it is attempted to be displaced as described above, it will be urged. Therefore, when an external force exceeding the urging force cannot be applied, the weight 4 cannot pass through, and by applying an external force larger than the urging force, the weight 4 can pass through. Such an external force is exerted by the weight 4 coming into contact with the tip 54 (contact portion 8) when moving.

Here, the torsion spring 50 used in the present embodiment has a free angle as an inferior angle, and the free angle is arranged toward the tail side. With such an arrangement, the contact portion 8 when the weight 4 retracts from the vicinity of the center 23 causes the load point side arm 53 to be loaded in the twisting direction. Therefore, when the weight 4 advances from the vicinity of the tail portion 22 toward the vicinity of the center 23 (see FIG. 3B), a twisting action in the opposite direction (rewinding direction) is applied to the coil portion 51. Therefore, the urging force is small, and when retreating from the vicinity of the center 23 to the vicinity of the tail portion 22, a twisting action in the original direction (winding direction) is applied, so that the urging force is large. Due to this difference in urging force, it is possible to facilitate the forward movement of the weight 4 and make it difficult to retreat. The play of the fixed point side arm 52 further facilitates the advance of the weight 4 even by rotation.

<Operating mode>
Next, the operation mode of this embodiment will be described. Since the present embodiment has the above configuration, first, before casting, the head (front portion) 21 of the lure 1 is turned upward as shown in FIG. 4 (a). , The shaft 3 is arranged substantially in the vertical direction, and the weight of the weight 4 can act in the direction of the tail portion (rear end portion) 22. In this state, the weight 4 can be moved to the vicinity of the tail (rear end) 22 by swinging the lure 1 to give a centrifugal force to the weight 4 or by applying an impact to accelerate it downward. The details of the moving method at this time will be described later.

In this state (the state where the weight 4 is located near the tail 22), the center of gravity of the entire lure 1 has moved to the side of the tail 22, and by casting while maintaining this, the heavy tail 22 is set as the head. You can fly in the air. The flight attitude at this time is stable because the other parts follow the traveling direction of the weight 4, which can help to increase the casting distance.

Further, as shown in FIG. 4B, the posture of the lure 1 that has landed on the water after casting is adjusted by the retrieve (reeling). At this time, the head 21 (eyelet 11) is attracted by the fishing line 9 so that only the head 21 is adjusted to sink. For example, by causing the lip 26 to receive water flow resistance, only the head 21 can be easily subsided. Then, when the head 21 is in a state of diagonally downward, the weight 4 starts moving due to its own weight, and finally moves to the front end support portion 24 of the shaft 3. Due to this movement, the retreat of the weight 4 is suppressed by the stopper 5.

When the lure 1 is moved (retrieved) in water while the retreat of the weight 4 is suppressed, for example, the side surfaces of the lip 26 and the lure body 2 vibrate as a whole due to the resistance of water. Even if there is a case, the vibration is a movement that swings around the position of the center of gravity (near the weight 4 = near the center 23), and the vibration with respect to the weight 4 is small. Therefore, a large external force in the direction in which the weight 4 retracts does not act. Even if an external force is generated in the retracting direction, the retracting of the weight 4 can be suppressed by the presence of the stopper 5 (contact portion 8) in the above-mentioned state.

The state of these weights 4 will be described in detail. First, at the time of casting and immediately after landing, as shown in FIG. 5A, the weight 4 is located in the vicinity of the tail 22. Then, the side of the head 21 is directed downward by the retrieve (reeling), so that the weight 4 moves forward in the direction of the head 21 due to its own weight. At this time, as a matter of course, the tip 54 (contact portion 8) of the load point side arm 53 of the torsion spring 50 is abutted during the movement, but as shown in FIG. 5 (b), the rotation of the torsion spring 50 The tip 54 (contact portion 8) can be lifted against the urging of a relatively small spring by the motion and the twisting action in the opposite direction (rewinding direction) with respect to the coil portion 51. Even when the tip 54 (contact portion 8) is lifted, the urging force of the coil portion 51 acts on the tip 54 (contact portion 8), so that the tip 54 (contact portion 8) is still present. The side surface 43 of the weight 4 is in sliding contact with the weight 4.

In this state, when the weight 4 completely passes (moves to the front end support portion 24), as shown in FIG. 5 (c), the tip 54 (contact portion 8) slides with the side surface 43 of the weight 4. It is released from the contact and the torsion spring 50 is restored to its original state. As a result, the retreat of the weight 4 is suppressed.

That is, as shown in FIG. 6A, when the weight 4 retracts, the tail side end surface 42 of the weight 4 comes into contact with the tip 54 (contact portion 8) of the load point side arm 53, and the torsion spring 50 causes the weight 4. You will be urged. At this time, in order to rotate the load point side arm 53, a twisting action of the coil portion 51 in the original direction (winding direction) is required, so that the weight 4 cannot be retracted unless a sufficient external force for that purpose is generated. It becomes a thing. For example, when the weight 4 retracts, as shown in FIG. 6B, the weight 4 exceeds the tip 54 (contact portion 8) to the extent that the load point side arm 53 is slightly rotated by the weight 4. It is not possible to move to the tail 22.

In this state, the weight 4 can move within a small range formed between the front end support portion 24 and the tip 54 (contact portion 8) of the load point side arm 53, but the retreat due to this movement is Since the contact portion 8 is present even if the distance is only a short distance, it is possible to prevent the vehicle from retreating further.

When casting again after the retrieval (reeling) is completed, the weight 4 is forcibly moved to the tail 22. At this time, the weight 4 is the tip 54 of the load point side arm 53 ( It must pass through the abutting portion 8). In this case, as shown in FIG. 6C, it is necessary to apply a sufficient external force to the load point side arm 53 of the torsion spring 50. Since the play of the fixed point side arm 52 of the torsion spring 50 is such that the torsion spring 50 cannot be rotated toward the tail 22 side, a load (torsion moment) larger than the urging by the torsion spring 50 is applied to the load point side arm. 53 must be loaded.

Therefore, as shown in FIGS. 7A and 7B, such a load can be applied by, for example, a method of vibrating the lure 1 in the vertical direction with the head 21 facing upward. As described above, since the movement is possible within a small range formed between the front end support portion 24 and the tip 54 (contact portion 8) of the load point side arm 53, the vibration in the vertical direction causes the movement. The weight moves in the range, and at that time, by accelerating the weight 4 (increasing the speed), the load moving in the direction of the tail 22 can be increased. A centrifugal force may be applied to the weight 4 toward the tail 22 by rotating the lure 1 largely with the side of the head 21 as a fulcrum.

<Summary of this embodiment>
As described above, according to the present embodiment, since the weight 4 is provided with the shaft 3 loosely fitted, the weight 4 can move along the shaft 3. Then, the weight 4 is stopped from advancing by the front end support portion 24 near the center 23, and the tip 54 (contact portion 8) of the load point side arm 53 of the torsion spring 50 is on the tail side of the weight 4 in the retracting direction. It becomes possible to contact the end face 42, and the movement in the backward direction is temporarily suppressed. On the other hand, since the weight 4 can be retracted to the tail 22 by moving beyond the urging force applied by the torsion spring 50, the weight 4 can be positioned in the vicinity of the tail 22 again.
<Modification example>

The embodiments of the present invention are as described above, but the above embodiments show an example of the present invention, and the present invention is not limited to the above embodiments. Therefore, some elements of the above embodiment may be modified and other elements may be added.

For example, the moving region of the weight 4 may be configured without using the shaft 3. FIG. 8 shows a first modification. In this modified example, the moving region of the weight 4 is divided by the bottom sliding contact base portion 31 and the two side restricting portions 32 and 33 in the space portion 20 of the lure main body 2. be. The weight 4 used here is typically a columnar (cylindrical in the figure) weight 4, and is arranged so that the axial direction is in the advancing / retreating direction. In the case of such a configuration, a part (bus) of the side surface of the weight 4 is linearly in contact with the surface of the bottom sliding contact base 31, and the weight 4 is maintained in the sliding contact state. , It is in a state where it can move forward and backward by sliding. The side restricting portions 32 and 33 are arranged so as to suppress the lifting of the weight 4, and by providing the side regulating portions 32 and 33 at a position away from the bottom sliding contact base portion 31, the bottom sliding contact base portion 31 and the side regulating portion 31 are provided. The weight 4 is held from the three directions of 32 and 33. Therefore, in a state where the lure body 2 is inverted (upside down), the side regulating portions 32 and 33 can be slidably contacted with a part (bus) of the side surface of the weight 4. ..

Also in the modified example of the above configuration, the tip 54 (contact portion 8) of the load point side arm 53 of the torsion spring 50 can abut on the surface (tail side end surface) 42 of the weight 4, and the contact portion 8 As in the above-described embodiment, the movement in the backward direction is temporarily suppressed by the contact by the above. Further, when the weight 4 moves (retracts) beyond the urging force applied by the torsion spring 50, it can be moved to the vicinity of the tail 22.

Further, FIG. 9 shows a second modification. In this modified example, three spheres 4a, 4b, and 4c are used as the weight 4. Here, three spheres 4a to 4c are shown by way of example, but the number of spheres 4a to 4c is arbitrary, and may be one or two, or four or more. Regardless of the number of spheres 4a to 4c, when the spheres 4a to 4c are used, the bottom rolling base 31 and the side regulation portions 32, 33 are regulated from the bottom and the side. Form a moving area. Basically, as in the first modification described above, the weight 4 is held from three directions by providing the two side restricting portions 32 and 33 at positions away from the bottom rolling base portion 31. be.

By using the spheres 4a to 4c in this way, these spheres 4a to 4c are basically movable by rolling on the surface of the bottom rolling base portion 31. Further, in a state where the lure body 2 is inverted (upside down), the spheres 4a to 4c can roll on the surfaces of the side regulating portions 32 and 33. The movement (advance / retreat) of the spheres 4a to 4c does not necessarily require rolling, and may slide and move without rotating. In the case of abrupt movement, it is assumed that the rolling speed cannot catch up with the moving speed, but the ability to roll makes the movement smooth. As long as the shape is rollable, the shape is not limited to the spheres 4a to 4c, and a columnar axis may be provided sideways.

In the first and second modifications described above, the bottom sliding contact base (bottom rolling base) 31 and the side regulating portions 32 and 33 are configured as separate members, but these are integrated into a gutter shape. It may be configured as a regulatory unit. In the case of a gutter-shaped structure, if an opening is formed so that the tip 54 (contact portion 8) of the load point side arm 53 of the torsion spring 50 can abut on the weight 4, the weight 4 as described above has an opening. Temporary movement suppression is possible.

Further, a modified example of the weight will be described. In the above embodiment, the shape of the weight 4 through which the shaft 3 is inserted is illustrated as a columnar shape, but it does not have to be columnar as long as it is columnar. For example, it may be an elliptical columnar shape as shown in FIG. 10A, or it may be a prismatic columnar shape as shown in FIG. 10B. In the case of these configurations, the posture of the weight 4 can be stabilized by setting the position of the through hole 40 to a position deviated from the center line. In the form in which the square columnar corners are arranged vertically as shown in FIG. 10B, when the weight 4 rotates around the axis of the shaft 3, the distance between the side surface of the weight 4 and the torsion spring 50 increases. Although it may change, even in this case, it is installed in a relative positional relationship so that contact by the contact portion 8 is possible.

Further, as the torsion spring 50, a double torsion spring is exemplified, but as shown in FIG. 10C, the torsion spring 50 may be a torsion spring 50 in which one coil portion 51 is formed. In this case, the contact portion 8 to be provided at the tip 54 of the load point side arm 53 can have the same effect by being provided linearly in the direction orthogonal to the axis of the shaft 3 by bending the tip 54 or the like. be able to.

In the above configuration, including the state shown in FIG. 10 (c), the position of the through hole 40 formed in the weight 4 is an eccentric position, and the lure is in a normal posture (dorsal side is upper side, ventral side). In the case of (lower), the posture of the weight 4 is also in the assumed state as shown in the figure. Using the same principle as this, the play of the fixed point side arm 52 of the torsion spring 50 is increased to secure a range in which the coil portion can sufficiently rotate, and the load point side arm 53 (or the contact portion 8) is secured. ) May be increased in weight so that the contact portion 8 reaches the passage space region. However, considering that the posture of the lure may not be stable when the lure is used, it is preferable that the contact portion 8 is arranged inside the passage space region as in the embodiment. In the case of the embodiment, the torsion spring 50 is preferable in that the torsion spring 50 does not necessarily have to be provided above (dorsal side) of the shaft 3 (weight 4).

Further, as shown in FIG. 10D, a stopper 105 may be used which is urged in the angular direction with respect to the axis of the shaft 3 by the compression spring 150. The stopper 105 has a shaft portion 151 that can be inserted into the compression spring 150, and the rear end side of the shaft portion 151 is inserted into the support portion 107. Further, the shaft portion 151 is provided with two flange-shaped plate-shaped members 152 and 153, and a compression spring 150 is arranged between one (tip side) plate-shaped member 152 and the support portion 107. It is a thing. When the shaft portion 151 retracts (rises), a repulsive force (urging force) against compression is generated between one of the plate-shaped members 152 and the support portion 107. In this case, the angle between the shaft 3 and the shaft portion 151 is set to be inclined toward the tail portion 22, and the weight 4 is exclusively urged in the forward direction. The other plate-shaped member 153 (on the rear end side) of the shaft portion functions as a positioning member behind the support portion 107, and the position of the contact portion 108 when it does not abut on the weight 4 is constant. It is to maintain. By configuring the stopper 105 so as to urge the weight in the angular direction in this way, it is possible to facilitate the movement of the weight 4 in the forward direction and suppress the movement in the backward direction. Further, it is preferable that the contact portion 108 is provided with a columnar shape in a horizontal direction so that the contact portion 108 can be linearly contacted (line contact) with the tail side end surface 42 of the weight 4.

As another modification, as shown in FIG. 11 (a), a cushioning member B is provided between the weight 4 and the rear end support portion 25, and as shown in FIG. 11 (b). There is also a configuration in which a cushioning member C is provided between the weight 4 and the front end support portion 24. These buffer members B and C are disk-shaped and have through holes through which the shaft 3 can be inserted.
