[0008] The problem that the invention aims to solve

[0009] The design of the rear handle of a fishing rod has the following problems: when gripping the handle body, a large force is applied to the joint between the handle body and the rod tip, making this joint prone to separation. While increasing the bonding area between the handle body and the rod can be considered to increase the joint strength, this results in a larger and heavier handle body, while also reducing design flexibility.

[0010] This invention was made to solve the above-mentioned problems, and its purpose is to provide a rear handle structure for a fishing rod that can improve design freedom and enhance joint strength.

[0011] Methods for solving problems

[0012] The rear handle of the present invention is a rear handle structure of a fishing rod comprising a rod and a handle body, characterized in that the handle body has: a main body portion having an enlarged diameter portion that expands as it moves away from the rod; and a first insertion portion extending from the main body portion toward the rod side and bonded to the inner circumferential surface of the rod.

[0013] According to the present invention, the inner circumferential surface of the rod is bonded to the first insertion portion of the handle body, and the main body of the handle body protrudes from the outside of the rod. Thus, the length of the first insertion portion ensures the joint strength, and the main body allows for greater design freedom in terms of size, shape, and design. Furthermore, since the main body has an enlarged diameter portion that expands away from the rod, grip is improved.

[0014] Furthermore, it is preferable that the handle body is hollow. According to the present invention, the handle body can be made lightweight.

[0015] Additionally, preferably, the handle body is hollow and has an opening that opens toward the rod tip. The rear handle of the fishing rod also has a rod stud, which has a base portion inserted into the interior of the handle body and a second insertion portion extending from the base portion and bonded to the inner circumferential surface of the first insertion portion.

[0016] According to the present invention, by inserting a rod bolt into the opening of the handle body and inserting the second insertion part of the rod bolt into the first insertion part, the joint strength between the rod and the handle body can be further improved.

[0017] Furthermore, it is preferable to have a protective ring that protects the opening of the handle body. According to the present invention, damage can be prevented when the handle body contacts the ground or the like.

[0018] Furthermore, the base portion of the preferred rod plug is preferably formed with a diameter larger than that of the rod and has a rod plug opening that opens to the side.

[0019] According to the present invention, the rod bolt can be made lighter.

[0020] Preferably, a handle opening that opens to the side is formed on the handle body. According to the present invention, by providing a handle opening, grip can be improved, and the weight of the handle body can be further reduced.

[0021] Furthermore, it is preferable that the handle body is solid. According to the present invention, the durability of the handle body can be improved.

[0022] Furthermore, it is preferable that a groove is formed on the handle body. According to the present invention, grip can be improved and the handle body can be made lighter.

[0023] Invention Effects

[0024] According to the present invention, a rear handle structure for a fishing rod can be provided that enables greater design freedom and improves joint strength. Attached Figure Description

[0040] <First Implementation Method>

[0041] Hereinafter, a first embodiment of the rear handle structure (hereinafter referred to as "rear handle structure") of the fishing rod of the present invention will be described with reference to the accompanying drawings. Furthermore, in the description of the drawings, the same elements are labeled with the same reference numerals, and repeated descriptions are omitted where appropriate. In the following description, "front and back," "left and right," and "up and down" are used in accordance with... Figure 1 and Figure 3A The arrow indicates the direction of the invention. This direction is used for illustrative purposes and does not limit the direction of the invention. The rear handlebar structure of the present invention has a "composite rear handlebar structure" consisting of multiple components and a "single rear handlebar structure" consisting of a single component. First, the composite rear handlebar structure will be described.

[0042] <Composite rear handle construction>

[0043] like Figure 1 as well as Figure 2 As shown, the rear handle structure R1 has a handle body 1, a rod 2, a protective ring 20, and a rod stop 30. The rod 2 is a cylindrical component that forms the main body of the fishing rod. The rod 2 can be a single piece or a connected structure composed of multiple rods.

[0044] like Figure 2 As shown, the handle body 1 of this embodiment is hollow and has a main body portion 10, a first insertion portion 11, and a large-diameter portion 12. The handle body 1 may be made of resin or metal, but is not limited to these.

[0045] like Figure 3A , Figure 3B As shown, the main body 10 is approximately truncated cone in shape, and has a bearing portion 10a, a first enlarged diameter portion 10b, and a second enlarged diameter portion 10c. The bearing portion 10a extends vertically outward from the base end of the first insertion portion 11. The bearing portion 10a is the part that abuts against the base end of the rod 2. The outer diameter of the bearing portion 10a is approximately the same as the outer diameter of the rod 2.

[0046] The first enlarged diameter portion 10b is a portion that is continuous with the receiving portion 10a and expands in diameter as it moves away from the first insertion portion 11. The first enlarged diameter portion 10b may be a flat surface, but in this embodiment, it is formed by a curved surface that is slightly concave towards the axis C. The second enlarged diameter portion 10c is a portion that is continuous with the first enlarged diameter portion 10b and expands in diameter as it moves away from the first insertion portion 11. The second enlarged diameter portion 10c may also be a flat surface, but in this embodiment, it is formed by a curved surface that is slightly concave towards the axis C. The inclination angle of the second enlarged diameter portion 10c relative to the axis C is smaller than the inclination angle of the first enlarged diameter portion 10b relative to the axis C. The length of the second enlarged diameter portion 10c in the axis C direction is longer than the length of the first enlarged diameter portion 10b in the axis C direction.

[0047] A handle opening 10d is formed in the second diameter expansion portion 10c, which opens to the side. The shape and number of handle openings 10d are not particularly limited, but in this embodiment, three openings with circumferentially inclined cuts are formed.

[0048] The first insertion part 11 extends from the main body 10 toward the rod 2 (see reference) Figure 1 The first insertion part 11 is inserted into the inside of the rod 2 and is formed to be smaller than the inner diameter of the rod 2. The outer peripheral surface of the first insertion part 11 and the inner peripheral surface of the rod 2 are bonded together with an adhesive. In addition, although the first insertion part 11 in this embodiment is cylindrical, it can be appropriately modified to fit the hollow shape of the rod 2.

[0049] The large-diameter section 12 and the main body section 10 extend continuously toward the butt end of the rod, forming a cylindrical shape. The large-diameter section 12 has an opening 13 that faces toward the butt end of the rod. Multiple fine grooves are formed on the outer circumferential surface of the large-diameter section 12 throughout the circumferential direction. These grooves may be omitted, but their presence improves grip. An extension 12a extending toward the axis C is formed on the inner circumferential surface of the large-diameter section 12. A protective ring 20 is installed around the periphery of the opening 13. The protective ring 20 is cylindrical and is made of resin, metal, or a soft material. The protective ring 20 fits into the inner circumferential surface of the large-diameter section 12 and covers the end of the large-diameter section 12 in the circumferential direction.

[0050] like Figure 4A , Figure 4B As shown, the rod plug 30 is hollow and has a second insertion portion 31 and a base portion 32. The second insertion portion 31 extends forward from the base portion 32 and is cylindrical in shape. The second insertion portion 31 is formed to be larger than the first insertion portion 11 (see reference 1). Figure 3A The inner diameter of the second insertion part 31 is small. The outer peripheral surface of the second insertion part 31 is bonded to the inner peripheral surface of the first insertion part 11 by an adhesive. The length of the second insertion part 31 can be appropriately set according to the bonding strength, but in this embodiment, it is shorter than the length of the first insertion part 11.

[0051] The base portion 32 is continuously formed with the second insertion portion 31 and is approximately truncated conical in shape. The base portion 32 is formed with a diameter larger than that of the rod 2. The base portion 32 has a small-diameter base portion 32a that is continuous with the second insertion portion 31, a large-diameter base portion 32b that is larger than the small-diameter base portion 32a, and four main body portions 32c that connect the small-diameter base portion 32a and the large-diameter base portion 32b. The small-diameter base portion 32a is annular in shape and is formed with a diameter larger than that of the base end of the second insertion portion 31. A stepped portion 32d is formed from the second insertion portion 31 and the small-diameter base portion 32a, extending outward in a radial direction. The large-diameter base portion 32b is cylindrical and is continuously formed with the main body portions 32c. The outer diameter of the large-diameter base portion 32b is smaller than the inner diameter of the protective ring 20. A stepped portion 32e extending outward in the radial direction is formed by the main body portion 32c and the large diameter portion 32b of the base.

[0052] The base body 32c is a plate-shaped portion connecting the small-diameter portion 32a and the large-diameter portion 32b. A groove 32f is formed on the surface of the base body 32c along its elongation direction. The groove 32f increases the strength of the base body 32c. Ribs may be provided instead of the groove 32f, or the groove 32f may be omitted. Laterally opening rod openings 33 are formed between adjacent base body portions 32c. The shape and number of rod openings 33 are not limited, but in this embodiment, four openings are formed that are approximately trapezoidal in side view.

[0053] Next, the assembly method for the rear handle structure R1 will be explained. The following assembly method is an example, and the order can be changed appropriately. Figure 3B As shown, first, the handle body 1 and the rod stop 30 are assembled. Adhesive is applied to the outer peripheral surface of the second insertion portion 31 of the rod stop 30, and the second insertion portion 31 of the rod stop 30 is inserted into the first insertion portion 11 of the handle body 1. At this time, the receiving portion 10a of the handle body 1 abuts against the stepped portion 32d of the rod stop 30, and the protruding portion 12a of the handle body 1 abuts against the stepped portion 32e of the rod stop 30. Furthermore, a cover plate 40 is installed inside the large-diameter portion 32b of the rod stop 30 using adhesive or the like. The rear surface (the surface on the butt end side) of the cover plate 40 can also be designed.

[0054] Next, a protective ring 20 is installed on the inner circumferential surface of the large diameter portion 12. Finally, adhesive is applied to the outer circumferential surface of the first insertion portion 11 of the handle body 1, and the first insertion portion 11 is inserted into the rod 2 until the base end of the rod 2 touches the receiving portion 10a.

[0055] According to the rear handle structure R1 of this embodiment described above, the inner circumferential surface of the rod 2 is bonded to the first insertion portion 11 of the handle body 1, and the main body portion 10 of the handle body 1 protrudes from the outside of the rod 2. Therefore, the length of the first insertion portion 11 ensures the joint strength, and the main body portion 10 allows for greater design freedom in terms of size, shape, and design. Furthermore, since the main body portion 10 has an enlarged diameter portion (first enlarged diameter portion 10b and second enlarged diameter portion 10c) that increases in diameter as it moves away from the rod 2, gripability is improved.

[0056] Furthermore, because the tilt angle is changed in the first expansion portion 10b and the second expansion portion 10c, it is easy to grip, has excellent design, and is easy to contact with a part of the body (elbow, arm, armpit, etc.). In addition, by making the handle body 1 hollow, the handle body 1 can be made lightweight.

[0057] Furthermore, since the main body 10 is hollow and has an opening 13 that opens towards the rod tip, inserting the rod stop 30 through the opening 13 and inserting the second insertion part 31 of the rod stop 30 into the first insertion part 11 creates a double structure, which further enhances the bonding strength between the rod 2 and the handle body 1. Additionally, since the rod stop 30 has stepped portions 32d and 32e that abut against the receiving part 10a and the protruding part 12a respectively, the insertion direction can be easily positioned. Furthermore, the contact between the stepped portion 32e and the protruding part 12a also prevents the handle body 1 and the rod stop 30 from wobbling.

[0058] In addition, the protective ring 20 that protects the opening 13 can prevent the handle body 1 from being damaged when it comes into contact with the ground or the like.

[0059] Furthermore, the base portion 32 of the rod stop 30 is formed to have a larger diameter than the rod 2 and has a rod stop opening portion 33 that opens to the side. As a result, the rod stop 30 can be made lighter.

[0060] Furthermore, a handle opening 10d is formed on the side of the main body 10 of the handle body 1. This improves grip and further enhances the lightweight of the handle body 1.

[0061] (Variation Example 1)

[0062] Next, as Figure 5 As shown, the handle body 1B of Modified Example 1 will be described. Regarding the main body portion 10B of the handle body 1B, the shape of the handle opening 10Bd differs from that of the first embodiment described above. The handle opening 10Bd is formed into a rectangular shape in the second diameter expansion portion 10Bc. A total of four handle openings 10Bd are formed in the circumferential direction of the main body portion 10B. Other structures and effects are the same as in the first embodiment, therefore, descriptions are omitted.

[0063] (Variation Example 2)

[0064] Next, as Figure 6 As shown, the handle body 1C of Modified Example 2 will be described. Regarding the main body portion 10C of the handle body 1C, the shape of the handle opening 10Cd differs from that of the first embodiment described above. The handle opening 10Cd is rectangular from the second enlarged diameter portion 10Cc to the large diameter portion 12. A total of four handle openings 10Cd are formed in the circumferential direction of the main body portion 10C. Other structures and effects are the same as in the first embodiment, therefore, descriptions are omitted.

[0065] As in variations 1 and 2 described above, the shape of the handle opening can be changed to increase lightweighting and design flexibility.

[0066] <Second Implementation Method>

[0067] Next, the rear handle structure of the second embodiment of the present invention will be described. For example... Figure 7A , Figure 7B As shown, in the second embodiment, the structure of the protective ring 20B and the rod bolt 30B installed on the main body 10 differs from that in the first embodiment. The rear handle structure R2 of the second embodiment will be described focusing on the differences from the first embodiment.

[0068] like Figure 7A , Figure 7B As shown, the protective ring 20B is thicker than that in the first embodiment. The protective ring 20B has a flange portion 20Ba and a shaft portion 20Bb extending vertically from the flange portion 20Ba. The shaft portion 20Bb is inserted into the inner circumferential surface of the large-diameter portion 32Bb of the base of the rod bolt 30B.

[0069] Furthermore, the rod plug 30B has a second insertion portion 31B and a base portion 32B. In this embodiment, the shape of the rod plug opening 33B formed in the base portion 32B differs from that in the first embodiment. The rod plug openings 33B extend in a direction perpendicular to the axis C, and multiple openings are arranged side by side in the direction of the axis C. In addition, the rod plug openings 33B are formed such that their width increases in the left-right direction as they move rearward.

[0070] The rear handle structure R2 described above can achieve roughly the same effect as the first embodiment. Furthermore, the protective ring 20B can protect the end of the large-diameter portion 12 and the base large-diameter portion 32Bb of the rod stop 30B. Additionally, as in this embodiment, the size and shape of the rod stop 30B can be appropriately shaped according to the intended use.

[0071] <Third Implementation Method>

[0072] Next, the rear handle structure of the third embodiment of the present invention will be described. For example... Figure 8A , Figure 8B As shown, in the third embodiment, the structure of the rod bolt 30C installed on the main body 10 differs from that in the first embodiment. The rear handle structure R3 of the third embodiment will be described focusing on the differences from the first embodiment.

[0073] like Figure 8A , Figure 8B As shown, the rod stop 30C in this embodiment is solid. The rod stop 30C has a second insertion portion 31C and a spherical base portion 32C. The outer diameter of the base portion 32C is larger than the inner diameter of the rod 2.

[0074] The rear handle structure R3 described above can achieve roughly the same effect as the first embodiment. Furthermore, the hollow handle body 1 allows for weight reduction, and the solid rod stop 30C improves the durability of the rear handle structure R3. Alternatively, the rod stop 30C can also be made hollow.

[0075] <Fourth Implementation Method>

[0076] Next, the rear handle structure of the fourth embodiment of the present invention will be described. For example... Figure 9A , Figure 9B As shown, in the fourth embodiment, the structure of the main body 10D and the rod bolt 30D inserted into the main body 10D differs from that in the first embodiment. The rear handle structure R4 of the fourth embodiment will be described focusing on the differences from the first embodiment.

[0077] like Figure 9A , Figure 9B As shown, the handle body 1D of this embodiment has a hollow main body portion 10D and a first insertion portion 11D extending from the main body portion 10D toward the rod 2 side. A rod bolt 30D is installed in the hollow portion of the main body portion 10D.

[0078] The main body 10D has a bearing portion 10Da, a first expanded diameter portion 10Db, and a reduced diameter portion 10Dc. The bearing portion 10Da extends vertically outward from the base end of the first insertion portion 11D. The bearing portion 10Da is the part that abuts against the base end of the rod 2. The outer diameter of the bearing portion 10Da is approximately the same as the outer diameter of the rod 2.

[0079] The first enlarged diameter portion 10Db is a portion that is continuous with the receiving portion 10Da and increases in diameter as it moves away from the first insertion portion 11D. The first enlarged diameter portion 10Db may also be a curved surface recessed towards the axis C, but in this embodiment it is formed as a flat surface. The reduced diameter portion 10Dc is a portion that is continuous with the first enlarged diameter portion 10Db and decreases in diameter as it moves away from the first insertion portion 11D. The reduced diameter portion 10Dc may also be a curved surface recessed towards the axis C, but in this embodiment it is formed as a flat surface. The length of the reduced diameter portion 10Dc in the axis C direction is longer than the length of the first enlarged diameter portion 10Db in the axis C direction. The reduced diameter portion 10Dc has an opening at its rear end.

[0080] A handle opening 10Dd is formed in the reduced diameter portion 10Dc, which opens to the side. The shape and number of handle openings 10Dd are not particularly limited, but in this embodiment, three openings cut along the axis C are formed.

[0081] The rod stop 30D has: a second insertion portion 31D extending toward the rod shaft 2; and a base portion 32D located inside the main body portion 10D. The rod stop 30D is generally cylindrical. The outer peripheral surface of the second insertion portion 31D is bonded to the inner peripheral surface of the first insertion portion 11D by an adhesive. The outer peripheral surface of the base portion 32D is bonded to the inner peripheral surface of the main body portion 10D by an adhesive.

[0082] The rear handle structure R4 described above can also achieve roughly the same effect as the first embodiment. Like the main body 10D of this embodiment, it can also be configured to have a reduced diameter portion 10Dc.

[0083] Furthermore, in the first to fourth embodiments, both the handle opening and the rod bolt opening can be omitted. Alternatively, the rod bolt or protective ring can be omitted.

[0084] <Single-type rear handle construction in the fifth embodiment>

[0085] Next, the single-type rear handle structure of the fifth embodiment of the present invention will be described. For example... Figure 10 As shown, in the fifth embodiment, the structure of the main body 10E differs from that in the first embodiment. The rear handle structure R5 in the fifth embodiment is composed of a single component.

[0086] like Figure 10 As shown, the rear handle structure R5 has a handle body 1E and a rod 2. In this embodiment, the handle body 1E is solid and has a main body portion 10E, a first insertion portion 11E, and a large-diameter portion 12E. The handle body 1E may be made of rubber, resin, or metal, but is not limited to these materials.

[0087] The main body 10E is approximately truncated cone in shape, and includes a bearing portion 10Ea, a first enlarged diameter portion 10Eb, and a second enlarged diameter portion 10Ec. The bearing portion 10Ea extends vertically outward from the base end of the first insertion portion 11E. The bearing portion 10Ea is the part that abuts against the base end of the rod 2. The outer diameter of the bearing portion 10Ea is approximately the same as the outer diameter of the rod 2.

[0088] The first enlarged diameter portion 10Eb is a portion that is continuous with the receiving portion 10a and expands in diameter as it moves away from the first insertion portion 11E. The first enlarged diameter portion 10Eb may be a flat surface, but in this embodiment, it is formed by a curved surface that is slightly concave towards the axis C. The second enlarged diameter portion 10Ec is a portion that is continuous with the first enlarged diameter portion 10Eb and expands in diameter as it moves away from the first insertion portion 11E. The second enlarged diameter portion 10Ec may be a flat surface, but in this embodiment, it is formed by a curved surface that is slightly concave towards the axis C. The inclination angle of the second enlarged diameter portion 10Ec relative to the axis C is smaller than the inclination angle of the first enlarged diameter portion 10Eb relative to the axis C. The length of the second enlarged diameter portion 10Ec in the axis C direction is longer than the length of the first enlarged diameter portion 10Eb in the axis C direction.

[0089] The large-diameter section 12E and the main body section 10E extend continuously towards the tail of the rod, forming a cylindrical shape. The rear end of the large-diameter section 12E is closed.

[0090] A groove 10Ed is formed in the second diameter expansion portion 10Ec, which is recessed relative to the surface. The shape and number of grooves 10Ed are not particularly limited. In this embodiment, it is elongated in the front-back direction, and a plurality of grooves are formed in the entire circumference of the second diameter expansion portion 10Ec.

[0091] The rear handle structure R5 described above can achieve roughly the same effect as the first embodiment. Furthermore, the solid main body 10E improves the durability of the handle body 1E. Additionally, the groove 10Ed formed in the handle body 1E improves grip and reduces the weight of the handle body 1E. Alternatively, the groove 10Ed can be omitted in the rear handle structure R5. Furthermore, the handle body 1E can also be hollow. This further enables weight reduction.

[0092] The embodiments of the present invention have been described above. The present invention is not limited to the foregoing embodiments, and appropriate modifications can be made to each structural element without departing from the spirit of the invention. For example, the diameter-expanding portion may be formed as a two-stage structure having a first diameter-expanding portion and a second diameter-expanding portion, but this is not a limitation; there may be one or more diameter-expanding portions.
