DETAILED DESCRIPTION OF THE INVENTION

[0018] Embodiment 1 A grip or a pipe 2 according to an embodiment of the present invention will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates will be set and referenced as appropriate.

[0019] A rod-shaped core material, pipe, or fishing rod (hereinafter referred to as fishing rod 1) is used together with a fishing line, a float, a fishhook, etc. to catch fish, and as shown in FIG. 1 , it is a rod-shaped member or pipe extending in an axial direction A, for example, the core material of a fishing rod. However, it is not limited to this. Fishing rod 1 may be used in any tool that requires a core material to be curved. Fishing rod 1 may also be, for example, the core material or pipe of a golf club. A grip or tube body 2 is attached to fishing rod 1.

[0020] The grip or tube body 2 is a handle for holding the fishing rod. However, it is not limited to this. The grip or tube body 2 may be any part that is attached to the fishing rod 1. The grip or tube body 2 has one first tube body portion 100 having a cylindrical shape. However, it is not limited to this. The grip or tube body 2 may have multiple tube body portions. The grip or tube body 2 may have a tube body 60 provided inside the first tube body portion 100. The tube body 60 may be, for example, a pipe-type reel seat.

[0021] The first tubular body portion 100 is a tubular body that constitutes the grip or tubular body 2. However, it is not limited to this. The first tubular body portion 100 may be any tubular body having a pipe shape that can be attached to the fishing rod 1. As shown in FIGS. 2 and 3, the first tubular body portion 100 has a first pipe main body portion 10 and a first partition portion 20.

[0022] The first tube main body 10 is a part having a cylindrical shape. The axial direction of the first tube main body 10 is the axial direction A of the fishing rod 1. The inner diameter R1 of the first tube main body 10 is larger than the diameter R of the fishing rod 1. A space formed in a cylindrical shape or the like is formed between the inner peripheral surface 10d of the first tube main body 10 and the fishing rod 1.

[0023] The first partition 20 is a wall provided at the end of the first pipe body 10. The first partition 20 is provided at one end 10a of the first pipe body 10 in a first direction A1, which is one direction of the axial direction A of the fishing rod 1. However, this is not limited to this. The first partition 20 may also be provided at the other end 10b of the first pipe body 10 in a second direction A2, which is the opposite direction to the first direction A1. The first partition 20 is connected as a single body to the inner circumferential surface of the one end 10a of the first pipe body 10. However, this is not limited to this. The first partition 20 may be connected as a separate body to the one end 10a of the first pipe body 10, or may be formed as an integral part. The first partition 20 extends from the one end 10a of the first pipe body 10 in a direction intersecting the axial direction A. The first partition 20 is formed along an intersecting plane intersecting the axial direction A. However, this is not limiting. The first partition wall portion 20 may be formed to protrude in the first direction A1 beyond the intersection C1, as shown in Fig. 5. The first partition wall portion 20 is formed with a first axial hole 21, a first outer partition wall 22, and a first inner partition wall 23, as shown in Figs. 2 and 3.

[0024] The first axial hole 21 is a hole formed in approximately the center of the first partition wall portion 20 in a front view seen from the -Y side. The first axial hole 21 is formed along the axial direction A. The first axial hole 21 is a hole through which the fishing rod 1 is inserted. The diameter r1 of the first axial hole 21 is shorter than the inner diameter R1 of the first pipe main body portion 10. The length d1 of the first axial hole 21 in the axial direction A is shorter than the length D1 in the axial direction A of the outer peripheral portion 20a of the first partition wall portion 20, which is the portion between the upper end of the first inner partition wall 23 and the upper end of the first outer partition wall 22. An adhesive member G, which is a soft elastic adhesive, is attached to the inner circumferential surface 21a of the first axial hole 21. However, this is not limited to this. A soft caulking may be attached to the inner circumferential surface 21a of the first axial hole 21. An adhesive member G or caulking may be applied from one or both side surfaces of the first partition wall portion 20 toward the axial direction A so as to close the gap between the first shaft hole 21 and the fishing rod 1. The inner peripheral surface 21a of the first shaft hole 21 becomes the opposing surface between the fishing rod 1 and the first partition wall portion 20 when the fishing rod 1 is inserted into the first shaft hole 21. The adhesive member G applied to the inner peripheral surface 21a of the first shaft hole 21 bonds or fixes the contacting or opposing surfaces of the fishing rod 1 and the first partition wall portion 20.

[0025] The first outer partition wall 22 is the -Y side portion of the first partition wall portion 20. The -Y side surface of the first outer partition wall 22 is formed from the outer peripheral surface 10c of the first pipe body portion 10 to the first axial hole 21. The first outer partition wall 22 forms the -Y side end of the grip or pipe body 2. However, this is not limited to this. In a grip or pipe body 2 consisting of multiple pipe bodies, the first outer partition wall 22 may contact the +Y side end of another pipe body. The first outer partition wall 22 has a portion that is inclined toward the +Y side. For example, as shown in FIG. 4(b), the first outer partition wall 22 may have a portion with a curved shape that is inclined toward the +Y side.

[0026] As shown in FIG. 3 , the first inner partition wall 23 is a portion on the +Y side of the first partition wall portion 20. The +Y side surface of the first inner partition wall 23 extends from the inner circumferential surface 10d of the first pipe body portion 10 to the first axial hole 21. The first inner partition wall 23 has a portion inclined toward the -Y side. However, this is not limited thereto. As shown in FIGS. 4 and 5 , the first inner partition wall 23 may be formed such that the length D1 in the axial direction A of the outer peripheral portion 20a of the first partition wall portion 20, which is the portion between the upper end of the first inner partition wall 23 and the upper end of the first outer partition wall 22, is longer than the length d1 in the axial direction A of the first axial hole 21. In FIG. 5 , the portion corresponding to the outer peripheral portion 20a is indicated by a two-dot chain line. For example, as shown in FIG. 4( a ), the first inner partition wall 23 may be in contact with the first outer partition wall 22 at an acute angle. The first inner partition wall 23 may have a curved portion that is inclined toward the -Y side, as shown in Fig. 4(b), for example. As shown in Fig. 5, the entire first inner partition wall 23 may be inclined toward the -Y side.

[0027] Next, how to use the grip or the tube body 2 will be described.

[0028] First, the first tubular portion 100 is prepared, and an adhesive member G is attached to the inner circumferential surface 21a of the first axial hole 21 of the first partition portion 20. Furthermore, the adhesive member G may be attached to at least one of the first outer partition 22 or the first inner partition 23. Next, the fishing rod 1 is inserted into the first tubular portion 100. Specifically, the fishing rod 1 is inserted into the first axial hole 21 of the first partition portion 20 of the first tubular portion 100. The first tubular portion 100 is bonded or fixed with the adhesive member G so that the fishing rod 1 faces the inner circumferential surface 21a of the first axial hole 21.

[0029] As described above, in the grip or tube 2 according to the first embodiment, the fishing rod 1 is inserted into the first shaft hole 21 of the first partition 20 and is supported by the inner peripheral surface 21a of the first shaft hole 21. As a result, even if misalignment occurs between the fishing rod 1 and the first partition 20 when the fishing rod 1 is bent, as shown in FIG. 2, cracks are suppressed, the fishing rod 1 is fixed, and gaps are less likely to occur between the fishing rod 1 and the first partition 20. Specifically, with conventional first partitions 20, when the fishing rod 1 is bent, load is applied to the bushings fixed to both ends of the tube, which creates gaps between the inner and outer peripheral surfaces of the bushings and the connecting surfaces of the tube, potentially damaging the tube. However, in the case of a fishing rod 1 and first tubular body portion 100 using the grip or tubular body 2 according to the first embodiment, when the fishing rod 1 is bent and shifts inward beyond the first shaft hole 21 of the first partition portion 20, the space secured by the slope of both sides of the inner circumferential surface of the first shaft hole 21 in the Y-axis direction allows the fishing rod 1 to shift, so that the grip or tubular body 2 is less likely to be subjected to load, the grip or tubular body 2 is less likely to be damaged, the fishing rod 1 is fixed, and a gap is less likely to occur between the fishing rod 1 and the first partition portion 20.

[0030] In the grip or tube 2 according to the first embodiment, the fishing rod 1 and the first partition 20 are bonded or fixed together by an adhesive member G, which is a soft elastic adhesive, applied to the inner circumferential surface 21a of the first axial hole 21. Furthermore, the adhesive member G may be applied to at least one of the first outer partition 22 or the first inner partition 23. As a result, even if a misalignment occurs between the fishing rod 1 and the first partition 20 when the fishing rod 1 moves up and down or is bent, for example, the adhesive member G, which is a soft elastic adhesive, will not peel off even when distorted, suppressing cracks, fixing the fishing rod 1, and making it less likely that a gap will occur between the fishing rod 1 and the first partition 20. In the fishing rod 1 and first tubular body portion 100 using the grip or tubular body 2 according to this embodiment 1, when the fishing rod 1 is bent and shifts inward beyond the first axial hole 21 of the first partition wall portion 20, the adhesive member G, which is a soft elastic adhesive, allows the fishing rod 1 to shift, so that the grip or tubular body 2 is less likely to be subjected to load, the grip or tubular body 2 is less likely to be damaged, the fishing rod 1 is fixed, and a gap is less likely to occur between the fishing rod 1 and the first partition wall portion 20.

[0031] Embodiment 2 In the above-described first embodiment, the first partition wall 20 of the first tubular body 100 extends from one end 10a of the first tubular main body 10 in a direction intersecting the axial direction A. Furthermore, the first tubular body 100 may be formed with a first fitting portion 30 that protrudes in the first direction A1. A grip or tubular body 2 according to a second embodiment of the present invention will be described below with reference to the drawings. Differences from the first embodiment will be mainly described. Other than the differences described, the grip or tubular body 2 is the same as or equivalent to the first embodiment.

[0032] The first tubular body portion 100 is a tubular body that constitutes the grip or tubular body 2. As shown in FIG. 6 , the first tubular body portion 100 has a first tubular main body portion 10, a first partition wall portion 20, and a first fitting portion 30.

[0033] The first fitting portion 30 is an attachment portion that fits into another component, such as another pipe or the first crack prevention member 110. The first fitting portion 30 is formed in an annular shape at one end 10a of the first pipe main body 10. The outer diameter of the first fitting portion 30 is shorter than the outer diameter of the first pipe main body 10. The first fitting portion 30 is formed to protrude in a first direction A1, which is one side of the axial direction A, beyond an intersection C that intersects with the axial direction A of the first pipe main body 10. However, this is not limited to this. The first fitting portion 30 may be formed, for example, by forming an annular notch in the circumferential direction of the outer peripheral surface of the one end 10a of the first pipe main body 10. The first fitting portion 30 may be formed, for example, by forming an annular notch in the outer peripheral surface of the first partition wall portion 20, as shown in FIG. 7. The first fitting portion 30 may be formed, for example, by forming an annular notch in the outer peripheral surface of one end portion 10a of the first pipe main body portion 10 and the first partition portion 20. The first fitting portion 30 may be formed by cutting a portion on the -Y side of one end portion 10a of the first pipe main body portion 10 to form a step between the one end portion 10a of the first pipe main body portion 10 and the first partition portion 20.

[0034] The first crack prevention member 110 is a member that protects the end surface of one end 10a of the first pipe main body 10. The first crack prevention member 110 covers the end surface of one end 10a of the first pipe main body 10. The first crack prevention member 110 is formed in an annular shape. The first crack prevention member 110 is formed so that it can fit into the first fitting portion 30, and the inner diameter of the first crack prevention member 110 is approximately equal to or slightly larger than the outer diameter of the first fitting portion 30. By fitting the first crack prevention member 110 into the first fitting portion 30, it is possible to prevent cracks from occurring at the end of the first pipe main body 10.

[0035] Embodiment 3 In the first embodiment, the first partition wall 20 of the first tubular body 100 extends from one end 10a of the first tubular body 10 in a direction intersecting the axial direction A. Furthermore, the first tubular body 100 may be formed with a groove 40 recessed toward the second direction A2. A grip or tubular body 2 according to a third embodiment of the present invention will be described below with reference to the drawings. Differences from the first embodiment will be mainly described. Other than the differences described, the grip or tubular body 2 is the same as or equivalent to the first embodiment.
