Description

The present invention relates to a joint type lure used for fishing.

Lure fishing using lures is widespread. The target of lure fishing using a lure is a large fish (hereinafter referred to as "fish eater") that mainly preys on small fish. The lure will fly in the air and land on the water by the cast. After landing, the lure will settle in the water under its own weight. The lure is swam to the desired depth (range) by a retrieve that winds up the line on a reel. Fish Eta bites on this lure. A hook is attached to the lure. Fish eaters can be caught by biting a lure and sticking a hook. As this kind of lure, there is a joint type lure in which the body is divided into a first body and a second body. The joint type lure has a flexible connecting part between the first body and the second body.

For example, as this type of lure, there is a lure body composed of a plurality of divided bodies (see, for example, Patent Document 1). In this lure, a plurality of divided bodies are connected by a flexible core material.

Japanese Unexamined Patent Publication No. 2013-09687

By the way, lures let fish eaters eat by letting them swim with natural movements that resemble swimming fish. In the joint type lure, the second body bends in the left-right direction with respect to the first body due to the water pressure received by the retrieve. The joint type lure is a swim that resembles a fish swim by bending the second body in the left-right direction.

However, the connecting portion of a general joint type lure has a structure in which the first body and the second body are simply connected so as to be flexible. For this reason, it is difficult to make the bending action of the second body resemble the natural movement of a fish. If the bending action of the second body is unnatural, the fish eater will be reluctant to bite.

The prior art has a structure in which a plurality of divided bodies are connected by a flexible core material. Therefore, it is difficult to select the shape of each divided body and the material of the core material.

Therefore, an object of the present invention is to provide a joint type lure capable of making a bending action of a joint type lure in which a first body and a second body are connected into a natural movement.

In order to achieve the above object, the present invention is a joint type lure including a first body and a second body that causes a bending action with respect to the first body, wherein the first body and the first body are provided. It is provided in the connecting portion with the two bodies, and is provided with a resistance portion that can generate bending resistance with respect to the first body in accordance with the bending action of the second body. The "bending resistance" in this specification and the documents of the claims is the resistance generated at the time of bending, and includes "rotational resistance" and "sliding resistance".

With this configuration, the bending speed of the second body, which causes a bending action with respect to the first body, is suppressed by the bending resistance provided by the resistance portion provided in the connecting portion. Therefore, the second body can cause a bending action of natural movement with respect to the first body.

Further, the resistance portion may have a resistor capable of generating rotational resistance or sliding resistance at a portion of the support shaft that serves as a fulcrum at which the second body causes a bending action. With this configuration, the second body causes a bending action centered on the bending axis, so that rotation resistance or sliding resistance is generated by the resistor. Therefore, the operating speed of the second body is suppressed by the rotation resistance or the sliding resistance at the time of the bending action, and the bending action becomes a natural one.

Further, the resistor has a hole portion supported by the support shaft of the first body and an facing arm projecting toward the second body, and the second body has the second body. It may have an engaging portion sandwiched between the arms. With this configuration, the resistor rotates while generating rotational resistance between the hole and the support shaft, and the rotational speed is suppressed. As a result, the bending speed of the second body with respect to the first body is suppressed, resulting in a natural bending action.

Further, the resistor has an opening hole that can slide laterally along the support axis of the first body and an facing arm that projects toward the second body. The two bodies may have an engaging portion for sliding the resistor in a direction intersecting the support shaft within the range of the opening hole. With this configuration, the resistor slides while generating sliding resistance when the opening hole slides laterally along the support shaft, and the sliding speed is suppressed. As a result, the bending speed of the second body with respect to the first body is suppressed, resulting in a natural bending action.

Further, the resistor has a hole portion supported by the support shaft of the first body and an engaging portion protruding toward the second body, and the second body has the second body. It may have a concave portion that accommodates a part of the engaging portion. With this configuration, the resistor rotates while generating rotational resistance between the hole and the support shaft, and the rotational speed is suppressed. As a result, the bending speed of the second body with respect to the first body is suppressed, resulting in a natural bending action.

According to the present invention, it is possible to suppress the speed of bending action in a joint type lure in which a first body and a second body are connected by bending resistance. Therefore, it is possible to make the bending action of the second body with respect to the first body a natural movement.

Therefore, the overall configuration will be described with reference to the first joint type lure 10 of FIG. 1, and the description of the overall configuration will be omitted in the second joint type lure 50 of FIG. 5 and the third joint type lure 60 of FIG. Further, in the following embodiment, the head side body is the second body 12 and the tail side body is the first body 11. In this specification and the documents of the claims, the anteroposterior direction is referred to as anterior in the head direction and posterior in the tail fin direction. The horizontal direction orthogonal to the front-back direction is called the left-right direction. In the following embodiments, the illustration of the hook is omitted.

(Joint type lure according to the first embodiment)
The first joint type lure 10 according to the first embodiment will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, the first joint type lure 10 has a form in which the second body 12 imitates the front half of a fish. A line eye 13 is provided on the front portion of the second body 12. A front hook eye 14 is provided at the lower part of the second body 12. Chest fins 15 are provided at the left and right positions of the front hook eye 14. The first body 11 is shaped like the rear half of a fish. A rear hook eye 16 is provided at the lower part of the first body 11. A dorsal fin 17 is provided on the upper part of the first body 11. A tail fin 18 is provided at the rear portion of the first body 11. The tail fin 18 may be either a soft material or a hard material. A connecting portion 20 is provided between the second body 12 and the first body 11.

As shown in FIGS. 1 and 2, the connecting portion 20 has a support shaft 21 provided on the first body 11 and a connecting ring 22 provided on the second body 12. The support shaft 21 is provided so as to extend in the vertical direction at the front portion of the first body 11. The connecting ring 22 is provided at the upper part and the lower part of the rear part of the second body 12. A space for arranging the connecting ring 22 is formed at a position where the connecting ring 22 of the second body 12 is provided. The connecting ring 22 has ring portions at the front portion and the rear portion, and the front ring portion is held by the holding shaft 23 provided on the second body 12. The rear portion of the connecting ring 22 projects toward the support shaft 21 of the first body 11. The connecting ring 22 has a rear ring portion hung on a support shaft 21 provided on the first body 11. The second body 12 and the first body 11 connected by the connecting ring 22 are capable of bending action around the support shaft 21. The support shaft 21 serves as a fulcrum for the bending action.

Then, between the upper and lower connecting rings 22, a resistance portion 30 that can generate bending resistance by causing the second body 12 to perform a bending action with respect to the first body 11 is provided. The resistance portion 30 of the first joint type lure 10 has a first resistance body 31 provided with a support hole 32 which is a hole portion inserted into the support shaft 21 of the first body 11. The first resistor 31 can be made of a resin material. By using the first resistor 31 as a resin material, the frictional resistance between the support hole 32 and the support shaft 21 can be appropriately set. The first resistor 31 is provided in the resistor accommodating portion 36 provided in the first body 11. The first resistor 31 is attached with the lower surface in contact with the resistor accommodating portion 36.

As shown in FIGS. 2 and 3, the first resistor 31 has opposed arms 33 projecting from the first body 11 toward the second body 12. The arm 33 is provided with a contact portion 34 in the opposite direction. The contact portion 34 has a curved surface so as to face the contact portion 34. The second body 12 is provided with an engaging shaft 35 which is an engaging portion protruding rearward. The engaging shaft 35 is positioned between the opposing contact portions 34 of the first resistor 31. That is, the first resistor 31 is in a state in which the engaging shaft 35 of the second body 12 is sandwiched between the arms 33 protruding toward the second body 12. The engaging shaft 35 is provided with a slight gap S between the engaging shaft 35 and the contact portion 34. The engaging shaft 35 is in line contact with the facing curved surface portion of the contact portion 34 to reduce the contact area. By reducing the contact area between the contact portion 34 and the engaging shaft 35, the resistance when the engaging shaft 35 moves in the axial direction is reduced.

As described above, in the first joint type lure 10, the first body 11 is provided with the first resistance body 31, and the engagement shaft 35 projecting rearward from the second body 12 between the arms 33 of the first resistance body 31. Is positioned. As a result, when the second body 12 causes a bending action with respect to the first body 11, the first resistor 31 of the first body 11 rotates about the support shaft 21 by the engaging shaft 35 of the second body 12. Be made to.

(Bending resistance in the first joint type lure)
The bending resistance generated in the first joint type lure 10 will be described with reference to FIGS. 4A and 4B. In FIG. 4, the second body 12 will be described by being bent downward in the figure. FIG. 4A shows the state at the beginning of bending of the second body 12. According to the first joint type lure 10, when the second body 12 causes a bending action with respect to the first body 11, the engaging shaft 35 also bends integrally. Since the first resistor 31 has a gap S between the engaging shaft 35 and the contact portion 34, the first resistance body 31 does not rotate until the bending angle θ1 at which the engaging shaft 35 abuts on the contact portion 34 on the bending side.

As shown in FIG. 4B, when the second body 12 further causes a bending action, the engaging shaft 35 rotates the first resistor 31 around the support shaft 21 via the arm 33. At this time, the first resistor 31 generates rotation resistance at the contact surface F1 between the support hole 32 and the support shaft 21. This rotation resistance acts in a direction in which the first resistor 31 suppresses the operation of the engaging shaft 35.

Further, in this embodiment, sliding resistance is generated at the contact surface F2 (FIG. 2) between the lower surface of the first resistor 31 and the resistor accommodating portion 36 of the first body 11. This sliding resistance also acts in a direction that suppresses the rotation of the first resistor 31 about the engagement shaft 35.

Therefore, in the bending action centered on the support shaft 21 of the second body 12, the bending speed is suppressed by the rotational resistance and the sliding resistance generated in the first resistor 31. As a result, the bending speed of the first body 11 with respect to the second body 12 is suppressed, resulting in a natural bending action. Further, as shown in FIG. 4B, the impact when the second body 12 comes into contact with the first body 11 can be suppressed.

As described above, according to the first joint type lure 10, the bending action (bending resistance) generated between the first resistor 31 and the support shaft 21 and the resistor accommodating portion 36 causes the bending action with respect to the second body 12. The bending speed of the first body 11 can be suppressed. Therefore, in the first joint type lure 10, the speed of the bending motion at the connecting portion 20 is suppressed, and the bending action can be made into a natural swim similar to that of a fish.

The state of FIG. 4B is a state in which the second body 12 is bent to the left and right at the maximum bending angle θ2. The rear end of the second body 12 comes into contact with the first body 11 and is at the limit of bending. After that, the second body 12 draws a line (not shown) connected to the line eye 13, so that a bending action is caused in the direction opposite to that of the first body 11. Then, the second body 12 generates rotation resistance and sliding resistance due to the first resistor 31 at the time of bending action in the left-right direction. Due to the rotational resistance and the sliding resistance of the second body 12, the speed of bending in the opposite direction is suppressed, and the second body 12 has a natural bending action. As described above, in the bending action of the first joint type lure 10, a natural operation in which the bending speed is suppressed is repeated. Therefore, according to the first joint type lure 10, it is possible to continuously swim with a natural bending action.

(Second joint type lure according to the second embodiment)
The second joint type lure 50 according to the second embodiment will be described with reference to FIGS. 5 to 7. The same components as those of the first joint type lure 10 according to the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 5, the second joint type lure 50 is a sliding body that slides in the left-right direction in which the second resistance body 51, which is a resistance portion, intersects the support shaft 21 of the first body 11. Other configurations are the same as those of the first joint type lure 10.

The second resistor 51 is provided with an elongated hole 52 which is an opening hole to be inserted into the support shaft 21 of the first body 11. The elongated hole 52 has a size that can be inserted into the support shaft 21, and extends in the left-right direction of the second resistor 51. The second resistor 51 is slidable along the support shaft 21 within the range of the elongated hole 52. The elongated hole 52 has a length that allows the second resistor 51 to move in the left-right direction in a state where the second body 12 is most bent with respect to the first body 11 (for example, the state of FIG. 7). ). The opening hole is not limited to the slotted hole 52. For example, it can be a plurality of grooves extending in the left-right direction.

As shown in FIG. 6, in this embodiment, the corner portions 55 at both ends of the second resistor 51 in the left-right direction are formed in an arc shape. Further, the bottom surface of the resistor accommodating portion 36 is formed on an inclined surface 37 that is inclined upward in the left-right direction from the portion of the support shaft 21. As a result, the second resistor 51 is in a state where the corner portions 55 at both ends in the left-right direction are in contact with the inclined surface 37.

Further, the second resistor 51 has an opposed arm 53 projecting from the first body 11 toward the second body 12. The arm 53 is provided with a contact portion 54 in the opposite direction. The contact portion 54 has a curved surface at which the contact portion 54 faces. The second body 12 is provided with an engaging shaft 35 projecting rearward. The engaging shaft 35 is positioned between the opposing contact portions 54 of the second resistor 51. As a result, in the second resistor 51, the arm 53 protruding toward the second body 12 comes into contact with the engaging shaft 35 of the second body 12. The second resistor 51 is provided with the lower surface in contact with the resistor accommodating portion 36 (similar to the first resistor 31 in FIG. 2).

As shown in FIG. 7, according to the second joint type lure 50, when the second body 12 causes a bending action with respect to the first body 11, the engaging shaft 35 also bends integrally. Then, the engaging shaft 35 of the second body 12 comes into contact with the contact portion 54 of the second resistor 51. After that, the engaging shaft 35 is also bent by the bending action of the second body 12. As a result, the second resistor 51 having the arm 53 with which the contact portion 54 is in contact is slid laterally.

The second resistor 51 causes sliding resistance between the lower surface and the resistor accommodating portion 36 when sliding. As shown in FIG. 6, the second resistor 51 causes sliding resistance between the corner portion 55 and the inclined bottom surface 37 of the resistor accommodating portion 36 when sliding (in the state of the alternate long and short dash line). Further, the second resistor 51 rises by sliding in the left-right direction along the inclined bottom surface 37 of the resistor accommodating portion 36. This rise also causes sliding resistance between the elongated hole 52, which is an opening hole, and the support shaft 21. The lateral movement speed of the second resistor 51 is suppressed by these sliding resistances. As a result, the second joint type lure 50 can suppress the bending speed of the second body 12 that causes a bending action with respect to the first body 11. Therefore, the second joint type lure 50 can make the bending action a natural swim that resembles a fish.

The second joint type lure 50 also undergoes a bending action in the opposite direction from the state shown in FIG. 7 by the retrieve. This bending action is also a natural bending action in which the bending speed is suppressed by the sliding resistance generated by the second resistor 51. Therefore, the second joint type lure 50 can also swim continuously with a natural bending action.

(Third joint type lure according to the third embodiment)
The third joint type lure 60 according to the third embodiment will be described with reference to FIGS. 8 and 9. The same components as those of the first joint type lure 10 according to the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 8, the third joint type lure 60 has a support portion 62 having a support hole 63 in which a third resistor 61, which is a resistance portion, is supported by a support shaft 21 of the first body 11, and a support portion 62. It has an engaging shaft 64, which is an engaging portion extending from the second body 12 in the direction of the second body 12. The second body 12 is provided with a slide hole 65 which is a concave portion into which the engaging shaft 64 of the third resistor 61 is inserted. The slide hole 65 is provided at the center position in the left-right direction of the second body 12. The slide hole 65 is formed in a size having a predetermined gap S with the engaging shaft 64. The slide hole 65 extends in the front-rear direction. The slide hole 65 can be a circular hole when the engaging shaft 64 is circular, and a square hole when the engaging shaft 64 is square. The engaging shaft 64 of the third resistor 61 has a length that keeps a predetermined length inserted into the slide hole 65 in a state where the second body 12 is most bent (for example, the state of FIG. 9). .. In the third resistor 61, the engaging shaft 64 protruding toward the second body 12 is housed in the slide hole 65 of the second body 12. The third resistor 61 is provided with the lower surface in contact with the resistor accommodating portion 36 (similar to the first resistor 31 in FIG. 2).

As shown in FIG. 9, according to the third joint type lure 60, when the second body 12 causes a bending action with respect to the first body 11, the slide hole 65 is also integrally bent. Then, the slide hole 65 of the second body 12 comes into contact with the engaging shaft 64 of the third resistor 61. After that, the slide hole 65 is further bent by the bending of the second body 12. As a result, the third resistor 61 into which the engaging shaft 64 is inserted rotates around the support shaft 21.

The third resistor 61 generates rotation resistance at the contact surface F1 between the support hole 63 of the support portion 62 and the support shaft 21. Further, sliding resistance is generated at the contact surface F2 (see FIG. 2) between the lower surface of the support portion 62 and the resistor accommodating portion 36. Further, a sliding resistance is generated in the sliding direction between the engaging shaft 64 and the slide hole 65. The rotation speed of the third resistor 61 is suppressed by these resistances. As a result, the third joint type lure 60 can suppress the bending speed of the second body 12 that causes a bending action with respect to the first body 11. Therefore, the third joint type lure 60 can make the bending action a natural swim that resembles a fish.

Also in the third joint type lure 60, the bending action in the opposite direction from the state shown in FIG. 9 is caused by the retrieve. This bending action is also a natural bending action in which the bending speed is suppressed by the resistance generated by the third resistor 61. Therefore, the third joint type lure 60 can also be made to swim continuously with a natural bending action.

(Deformation embodiment)
The arrangement relationship of the connecting portion 20 between the first body 11 and the second body 12 may be reversed in the front-rear direction. For example, in the case of the first joint type lure 10 in the first embodiment, the support shaft 21 and the first resistance body 31 are provided on the second body 12 of the head side body and engage with the first body 11 of the tail side body. It can be configured to include a shaft 35. Similarly, the second joint type lure 50 and the third joint type lure 60 can be arranged upside down.

Further, the above-mentioned gap S and the bending angles θ1 and θ2 of the second body 12 are also examples. There is no gap S, and the resistors 31, 51, 61 can be configured to rotate or slide from the beginning of bending of the second body 12.

Further, the above-described embodiment shows an example, and the first body 11 and the second body 12 may be an integrated type in which the left and right sides are integrated as shown in the figure, or a split type in which the left and right sides are divided into left and right sides. Each part constituting the joint type lure can be changed without impairing the gist of the present invention, and the present invention is not limited to the above-described embodiment.

Further, the configurations in each of the above-described embodiments may be combined. For example, as in the second joint type lure 50, a configuration in which the bottom surface of the resistor accommodating portion 36 is set as an inclined surface 37 to generate sliding resistance may be combined in another embodiment.
