Summary of the Invention
Problems to be Solved by the Invention
[0004] A lure according to the prior art is configured to move on the water surface or in the water while rotating a propeller portion when a fishing line is pulled. The lure attracts the interest of target organisms such as small fish by the sounds and splashes generated by the rotation of the propeller portion.
[0005] However, there is room for improvement in the prior art in terms of improving the convenience of the propeller portion.
[0006] One object of the present disclosure is to provide a lure that improves the convenience of the propeller portion.
Means for Solving the Problems
[0007] A lure according to the first aspect of the present disclosure includes a body, a rotating portion, and a propeller portion. The rotating portion is rotatably attached to the body. The propeller portion is detachably attached to the rotating portion.
[0008] According to the first side view of the lure, the propeller section is detachably attached, allowing it to be replaced, thus improving the convenience of the propeller section. In other words, with the lure, for example, it is possible to replace the propeller section with one of a different shape or size depending on the fishing situation, or to replace a damaged propeller section with a new one, thus improving the convenience of the propeller section.
[0009] In a lure with a second side surface corresponding to a first side surface, the rotating part is provided with a groove. The propeller part is provided with a projection that can engage with the groove, and is attached to and detached from the rotating part by the projection engaging with the groove and sliding.
[0010] According to the second side view of the lure, the propeller section is attached and detached by the protrusion engaging with the groove of the rotating section and sliding, so that the propeller section can be easily attached to the rotating section and the propeller section can be easily removed from the rotating section.
[0011] In a lure with a third side conforming to a second side, the groove is provided with a locking portion for engaging a projection.
[0012] According to the third side of the lure, the protrusion of the propeller is locked into the locking part of the groove in the rotating part, thus preventing the propeller from falling off the rotating part.
[0013] In a lure with a third side conforming to a second or third side, the groove comprises an opening and a stopper. The opening is formed on the front end side and is configured to allow a projection to pass through. The stopper is formed on the rear end side and restricts the movement of the projection.
[0014] In the fourth side of the lure, the propeller portion is inserted through the opening of the groove in the rotating portion, and its movement is restricted by the stopper portion, so that the propeller portion can be attached to the desired position on the rotating portion. In the lure, for example, when the fishing line is pulled, the force from the water on the propeller portion acts toward the rear end. In the fourth side of the lure, since a stopper portion is formed on the rear end side of the groove, even when a force acts toward the rear end, it is possible to prevent the propeller portion from falling off from the rear end.
[0015] In a lure with a fifth side conforming to any one of the second to fourth sides, the body has a recess formed on the outer surface on the side of the rotating part. The propeller part is removed from the rotating part by the projection moving from the groove into the space formed by the recess, when the rotating part is rotated so that the groove is in a position corresponding to the recess.
[0016] According to the fifth side view of the lure, the propeller section can be easily removed from the rotating section because the projection moves from the groove of the rotating section to the space formed by the recess.
[0017] In a lure with a sixth side conforming to any one of the second to fifth sides, the body has a recess formed on the outer surface on the side of the rotating part. The propeller is attached to the rotating part by the projection moving from the space formed by the recess into the groove when the rotating part is rotated so that the groove is in a position corresponding to the recess.
[0018] According to the lure on the sixth side, the propeller is attached by moving the projection from the space formed by the recess to the groove of the rotating part, thus allowing the propeller to be easily attached to the rotating part.
[0019] In a lure with a seventh side conforming to a fifth or sixth side, the recess is formed on the outer surface of the body in a location other than the vertically downward portion.
[0020] According to the lure of the seventh side surface, it is possible to further suppress the propeller part from falling off the rotating part. That is, the groove part of the rotating part is likely to be vertically below the lure due to the weight of the propeller part when the propeller part is attached. Since the propeller part can be removed when the rotating part rotates so that the groove part corresponds to the concave part, when the concave part is formed at a part vertically below the body, the groove part is likely to be in a position corresponding to the concave part, and the propeller part is likely to fall off the rotating part. In the lure of the seventh side surface, since the concave part is formed at a part other than the part vertically below on the outer surface of the body, the groove part to which the propeller part is attached is unlikely to be in a position corresponding to the concave part, and thus it is possible to further suppress the propeller part from falling off the rotating part.
[0021] In the lure of the eighth side surface according to the seventh side surface, a plurality of concave parts are formed. The plurality of concave parts are formed symmetrically with respect to a virtual plane passing through the center in the left - right direction of the body.
[0022] According to the lure of the eighth side surface, since the plurality of concave parts are formed in a well - balanced manner in the left - right direction of the body, the design property can be improved. In the lure of the eighth side surface, since the plurality of concave parts are formed in a well - balanced manner in the left - right direction of the body, when the fishing line is pulled, the lure can move in a stable posture along the direction in which the fishing line is pulled.
Effect of the Invention
[0023] According to the lure of the present disclosure, the convenience in the propeller part can be improved.

[Figure 9] Figure 9 is a diagram illustrating the attachment and detachment of the propeller section. [Modes for carrying out the invention]
[0025] Lure 2 according to an embodiment will be described with reference to Figures 1 to 3. Lure 2 is, for example, a lure for catching large fish (fish-eaters) that prey on small fish. Large fish include largemouth bass, yellowtail, juvenile yellowtail, and sea bass. Lure 2 is shaped to resemble a small fish.
[0026] In this specification, the following terms indicating directions, “front,” “rear,” “forward (front side),” “backward (rear side),” “left,” “right,” “leftward,” “rightward,” “up,” “down,” “upwards,” and “downwards,” as well as any other similar terms indicating directions, are defined as follows:
[0027] "Front" and "forward (front side)" indicate the direction of movement of lure 2 as it is pulled by the fishing line to which the fishing line is connected. "Back" and "rear (rear side)" are the opposite directions of movement. "Front-back direction" corresponds to the longitudinal direction of lure 2.
[0028] "Up" and "upward" indicate the direction toward the water surface when Lure 2 is moving forward in the water. "Down" and "downward" indicate the direction toward the bottom when Lure 2 is moving forward in the water. "Left," "leftward," "right," and "rightward" are defined based on "up" and "down."
[0029] As shown in Figures 1 to 3, lure 2 comprises a body 4, a rotating part 6, and a propeller part 8. Lure 2 also comprises a shaft part 10 (see Figure 3) and a wire 12. All or part of the components constituting the body 4 may be made of resin or metal.
[0030] The body 4 is formed to extend in the front-rear direction. The body 4 is formed to be hollow. The body 4 may be filled with a filling material. A recess 20 is formed in the body 4. The recess 20 will be described later with reference to Figure 8. The outer surface 4a of the body 4 may be decorated by painting, printing, or attaching fabric.
[0031] The rotating part 6 is rotatably mounted to the body 4, as shown by arrow A in Figures 1 and 2. The rotating part 6 will be described with reference to Figures 4 to 6. The rotating part 6 is formed in a cylindrical shape. The rotating part 6 has a groove 30. The rotating part 6 has an axial hole 32 and a rotating part side recess 34.
[0032] The shaft hole 32 is a hole that penetrates the rotating part 6 in the front-rear direction. The diameter of the shaft hole 32 is set to be larger than the shaft diameter of the shaft part 10 (see Figure 3). The shaft part 10 is inserted through the shaft hole 32. As shown in Figure 3, the shaft part 10 is inserted into and fixed in the insertion hole 22. The insertion hole 22 is formed on the rear end side of the body 4. This allows the rotating part 6 to rotate relative to the body 4 with the shaft part 10 as its central axis.
[0033] The groove 30 is formed on the outer surface 6a of the rotating part 6. The groove 30 is formed in a groove shape that extends along the front-rear direction. The groove 30 is the part to which the propeller part 8 is attached. The projection 40 of the propeller part 8 (see Figure 3), which will be described later, engages with the groove 30 to attach the propeller part 8.
[0034] Here, the propeller section 8 will be described with reference to Figure 7. As shown in Figure 7, the propeller section 8 includes a projection 40. The propeller section 8 includes a blade section 42 and a connecting section 44.
[0035] The blade section 42 is formed, for example, in a curved shape. The blade section 42 is shaped to rotate the rotating section 6 to which the propeller section 8 is attached when the fishing line is pulled and subjected to a force F from the water (see Figure 3). As a result, when the fishing line is pulled, the lure 2 generates sound and splashes due to the rotation of the propeller section 8, attracting the interest of the target organism.
[0036] The projection 40 is formed to protrude from the blade portion 42. The projection 40 is formed in a shape that can engage with the groove portion 30 of the rotating portion 6. The projection 40 is formed, for example, in a flat plate shape. The projection 40 is formed to extend along the front-rear direction. The connecting portion 44 is the part that connects the blade portion 42 and the projection 40. The propeller portion 8 is detachable from the rotating portion 6. The attachment and detachment of the propeller portion 8 will be described later with reference to Figure 9.
[0037] The groove 30 will be described in detail with reference to Figures 4 to 6. The groove 30 includes a locking portion 30a. The groove 30 includes an opening 30b and a stopper portion 30c.
[0038] The locking portion 30a is formed to partially cover the groove-shaped portion of the groove 30. Specifically, as shown in Figure 5, the locking portion 30a is formed to extend continuously from both ends of the groove 30 in the left-right direction. The locking portion 30a is formed to cover the vicinity of both ends of the groove-shaped portion in the left-right direction while ensuring space for insertion of the projection 40 of the propeller portion 8. As a result, the locking portion 30a locks the projection 40 of the propeller portion 8 attached to the groove 30 (see Figure 9, described later). Therefore, the propeller portion 8 is prevented from falling off the rotating portion 6.
[0039] The opening 30b is formed on the front end side of the groove 30. The opening 30b is an opening that is open at the front. The opening 30b is formed in a shape that allows the projection 40 of the propeller section 8 to be inserted through it.
[0040] The stopper portion 30c is formed on the rear end side of the groove portion 30. The stopper portion 30c is, for example, a wall erected from the groove-shaped portion of the groove portion 30. The stopper portion 30c restricts the movement of the projection portion 40 of the propeller portion 8 by contacting the projection portion 40 of the propeller portion 8 with the stopper portion 30c. In other words, the stopper portion 30c restricts the rearward movement of the propeller portion 8 by contacting the projection portion 40. As a result, the propeller portion 8 is attached to the desired position on the rotating portion 6. Because the lure 2 is equipped with the stopper portion 30c, etc., even when the fishing line is pulled and a force F from the water (see Figure 3) acts toward the rear end, the detachment of the propeller portion 8 from the rear end side is suppressed.
[0041] The rotating part side recess 34 is formed on the outer surface 6a of the rotating part 6. The rotating part side recess 34 is formed to be recessed from the outer surface 6a of the rotating part 6. The rotating part side recess 34 is formed to extend along the front-rear direction of the rotating part 6. Multiple rotating part side recesses 34 are formed. For example, two rotating part side recesses 34 are formed. As shown in Figure 5, the multiple rotating part side recesses 34 are formed symmetrically with respect to a virtual plane B passing through the center of the rotating part 6 in the left-right direction. The multiple rotating part side recesses 34 are formed to be symmetrical left-right in a front view of the rotating part 6.
[0042] Here, the recess 20 of the body 4 will be described in detail with reference to Figures 1, 2, and 8. The body 4 includes the recess 20. The recess 20 is formed on the outer surface 4a of the body 4 on the side of the rotating part 6, as shown in Figures 1 and 2. The recess 20 is formed on the outer surface 4a of the body 4 on the rear end side. The recess 20 is formed to be recessed from the outer surface 4a of the body 4. The recess 20 is formed to extend along the front-rear direction of the body 4. Multiple recesses 20 are formed. For example, two recesses 20 are formed. The recesses 20 are formed on the outer surface 4a of the body 4 in a location other than the vertically lower portion 4b. Specifically, the multiple recesses 20 are formed symmetrically with respect to a virtual plane C passing through the center of the body 4 in the left-right direction, as shown in Figure 8. The multiple recesses 20 are formed to be symmetrical from left to right in a front view of the body 4.
[0043] The recess 20 is formed in a predetermined range within the 360-degree outer circumference of the outer surface 4a of the body 4 when viewed from the front. The predetermined range can be set to any value. For example, the predetermined range can be set to 30 degrees.
[0044] Since the recess 20 is a recess, a space 20a is formed in the body 4 by the recess 20. In Figure 8, for ease of understanding, the space 20a is shown with a dashed line. The propeller part 8 of the lure 2 is attached and detached using this space 20a. The attachment and detachment of the propeller part 8 will be described later with reference to Figure 9.
[0045] As shown in Figures 1 and 2, the recess 34 on the rotating part side of the rotating part 6 is shaped to be continuous with the recess 20 in the front-to-back direction when the rotating part 6 rotates to a position corresponding to the recess 20 of the body 4. As a result, in the lure 2, the recess flows from the recess 20 to the recess 34 on the rotating part side in the front-to-back direction, improving the design.
[0046] As shown in Figures 1 to 3, the wire 12 comprises a first eye 40a and second eyes 40b and 40c. The wire 12 is made of wire material. The wire 12 is formed to extend in the front-rear direction. As shown in Figure 3, the wire 12 is attached to the body 4 and the shaft portion 10. Each eye 40a to 40c is provided so that at least a portion of it is exposed from the body 4. The first eye 40a is provided on the front end side of the lure 2. The first eye 40a is configured to be connected to a fishing line. The second eye 40b is provided on the rear end side of the lure 2. The second eye 40b is configured to be connected to a hook portion. The second eye 40c is provided on the lower end side of the lure 2. The second eye 40c is configured to be connected to a hook portion. The second eye 40c is provided between the first eye 40a and the second eye 40b.
[0047] The attachment and detachment of the propeller section 8 will be explained in detail with reference to Figure 9. Figure 9 is an enlarged perspective view of the rotating section 6 and the area around the propeller section 8 of the lure 2. In Figure 9, the propeller section 8 before removal or after attachment is shown with a solid line. In Figure 9, the propeller section 8 after removal or before attachment is shown with a dashed line.
[0048] The propeller section 8 is detachably attached to the rotating section 6. Specifically, the propeller section 8 is attached to and detached from the rotating section 6 by the projection 40 engaging with the groove 30 of the rotating section 6 and sliding (see arrows D and E). The attachment and detachment of the propeller section 8 is performed by the user.
[0049] More specifically, when the propeller section 8 is removed from the rotating section 6, the rotating section 6 is first rotated so that the groove 30 of the propeller section 8 is in a position corresponding to the recess 20 of the body 4. Specifically, the rotating section 6 is rotated until the opening 30b of the groove 30 coincides with the recess 20 of the body 4. As a result, the lure 2 is in a state where the space 20a formed by the opening 30b of the groove 30 and the recess 20 of the body 4 is in communication with each other.
[0050] When the rotating part 6 is rotated so that the groove 30 of the propeller part 8 is in a position corresponding to the recess 20, the projection 40 moves from the groove 30 to the space 20a of the recess 20 (see arrow D). Specifically, the projection 40 slides in the groove 30 of the rotating part 6 and then moves to the space 20a of the recess 20. As a result, the propeller part 8 can be easily removed from the rotating part 6.
[0051] In lure 2, when the rotation state of the rotating part 6 is such that the groove 30 is in a position other than the position corresponding to the recess 20, the projection 40 cannot move from the groove 30 into the space 20a of the recess 20. Therefore, the propeller part 8 will not fall off the rotating part 6.
[0052] When the propeller section 8 is attached to the rotating section 6, the rotating section 6 is first rotated so that the groove 30 of the propeller section 8 is in a position corresponding to the recess 20 of the body 4. Specifically, the rotating section 6 is rotated until the opening 30b of the groove 30 coincides with the recess 20 of the body 4. As a result, the lure 2 is in a state where the space 20a formed by the opening 30b of the groove 30 and the recess 20 of the body 4 is in communication with each other.
[0053] When the rotating part 6 is rotated so that the groove 30 of the propeller part 8 is in a position corresponding to the recess 20, the projection 40 moves from the space 20a of the recess 20 to the groove 30 (see arrow E). Specifically, the projection 40 moves from the space 20a of the recess 20 to the groove 30 of the rotating part 6 and slides along the groove 30. This allows the propeller part 8 to be easily attached to the rotating part 6.
[0054] In the above example, the propeller portion 8 of the lure 2 is shown as having one, but there may be multiple propeller portions 8. In the above example, the recess 20 of the body 4 is shown as having two, but there may be one recess 20 or three or more. In the above example, the recess 34 on the rotating portion side of the rotating portion 6 is shown as having two, but there may be one recess 34 on the rotating portion side or three or more.
[0055] As used herein, the expression "at least one" means "one or more" of the desired options. For example, as used herein, "at least one" means "only one option" or "both of the two options" if there are two options. As another example, as used herein, "at least one" means "only one option" or "a combination of two or more any options" if there are three or more options. [Explanation of symbols]
