Description

The present invention relates to a spacer for a fishing rod.

Conventionally, when attaching a reel seat to the rod shaft of a fishing rod, a cylindrical spacer is inserted as a gap member to fill the gap between the inner circumferential surface of the reel seat and the outer circumferential surface of the rod. The spacer is adhered to the reel seat and the rod, respectively, with adhesive.

JP 2008-11703 A

Cylindrical spacers that are glued together with adhesive may be unable to follow the curvature of the rod and break inside the reel seat, causing abnormal noise. In addition, if the spacer is unable to follow the curvature of the rod and becomes too stiff, the rod may break and the desired strength may not be ensured. To solve these problems, some spacers are divided and positioned separately, but it is difficult to apply adhesive and attach them to the specified position, and even if they are attached, the position of the spacer may shift in the axial direction of the rod before the adhesive hardens, making assembly difficult.

The present invention was made to solve the above problems, and aims to provide a spacer for a fishing rod that does not hinder the bending of the rod and is easy to assemble.

To solve the above problem, the present invention provides a fishing rod spacer that is interposed between a rod shaft and a reel seat, and is characterized by having a cylindrical shape and multiple cylindrical sections that are spaced apart from each other along the axial direction, and at least one connecting section that connects the cylindrical sections together.

According to the present invention, since multiple cylindrical parts are spaced apart, bending of the rod is not hindered and the spacer can be prevented from being damaged inside the reel seat. In addition, since multiple cylindrical parts are connected by connecting parts, when adhesive is applied and the cylindrical parts are inserted into the reel seat, it is possible to prevent the cylindrical parts from shifting from their designated positions inside the reel seat, improving assembly.

It is also preferable that the cylindrical portions are arranged so that the distance between them increases from the base to the tip.

According to the present invention, the cylindrical sections are spaced apart at the tip side of the rod where the rod is more likely to bend, making it less likely that the bending of the rod will be impeded. In addition, the spacing between the cylindrical sections is smaller at the base side of the rod where the rod is less likely to bend, which increases the strength of the fishing rod spacer.

The cylindrical portion preferably includes an inner wall portion into which the rod is inserted and which is in contact with the outer peripheral surface of the rod, an outer wall portion which is concentric with the inner wall portion and has a larger diameter than the inner wall portion and which is in contact with the inner peripheral surface of the reel seat, a hollow portion formed between the inner wall portion and the outer wall portion, and a vertical rib which radially connects the inner wall portion and the outer wall portion and extends in the axial direction.

According to the present invention, the mass of the cylindrical portion can be reduced, making it lighter, and the strength can be increased by providing vertical ribs.

Of the cylindrical portions, it is preferable that the cylindrical portion arranged at the end on the side where the rod or the reel seat is inserted has a lid formed on the side where the rod is inserted to close the hollow portion.

This invention can prevent adhesive from entering the hollow portion and prevent the mass from increasing. In addition, when inserting the spacer into the reel seat, the adhesive can be inserted while being pressed with the lid, so that the adhesive can be applied evenly and the adhesive strength can be increased.

It is also preferable that the connecting portion is arranged so that the portion farthest from the central axis in the radial direction is located inside the outer peripheral surface of the outer wall portion.

According to the present invention, the connecting portion does not come into contact with the inner peripheral surface of the reel seat, so adhesive can be prevented from adhering to the connecting portion.

It is also preferable that the connecting portion has a rectangular shape in a plan view and is formed to be wide in the circumferential direction.

The present invention makes it possible to prevent the connecting part from impeding the bending of the rod.

It is also preferable that the outer peripheral surface of the outer wall portion is formed with a groove that is recessed toward the inner wall portion.

According to the present invention, the cylindrical portion can be firmly bonded to the inner surface of the reel seat, etc., by using the anchor effect.

It is also preferable that the lid portion has a first inclined portion that is inclined toward the outer wall portion. It is also preferable that the lid portion has a second inclined portion that is inclined toward the inner wall portion.

According to the present invention, the adhesive flows from the end of the lid member on the tip side through the first inclined portion toward the outer wall portion. Also, the adhesive flows from the end of the lid member on the tip side through the second inclined portion toward the inner wall portion. This makes it possible to prevent the adhesive from accumulating in the lid portion.

The fishing rod spacer of the present invention can provide a fishing rod spacer that does not hinder the bending of the rod shaft and is easy to assemble.

First Embodiment
The fishing rod spacer according to the first embodiment of the present invention will be described below with reference to the drawings. Each embodiment is merely an example, and each embodiment can be appropriately combined to configure the present invention. In addition, the reference numerals and descriptions of the same members may be omitted.

As shown in Figures 1 and 2, the fishing rod spacer 1 has a cylindrical portion 10 and a connecting portion 20. The fishing rod spacer 1 is used when attaching a reel seat 11 (see Figure 9) to a rod shaft 12 of a fishing rod, which will be described later, and is interposed between the rod shaft 12 and the reel seat 11 via an adhesive.

The fishing rod spacer 1 is integrally formed from resin. Examples of resin include ABS resin, ASA resin, PLA resin, PP resin, PET resin, epoxy resin, acrylic resin, polycarbonate resin, polyamide resin, and resins containing reinforcing fibers such as carbon. The fishing rod spacer 1 can be easily manufactured using a 3D printer or the like. In this embodiment, the fishing rod spacer 1 is integrally formed, but the cylindrical portion 10 and the connecting portion 20 may be manufactured independently and then combined to form the spacer. This allows, for example, the axial position of the adjacent cylindrical portions 10, 10 to be appropriately adjusted by changing the length of the connecting portion 20.

Next, the cylindrical portions 10 will be described with reference to Figures 1 to 6. The cylindrical portions 10 are cylindrical in shape, and six of them are arranged in the axial direction of the rod 12. The spacing between the cylindrical portions 10 is set to gradually increase toward the rod tip side and gradually decrease toward the rod base side. In this embodiment, there are six cylindrical portions 10, but the number and spacing of the cylindrical portions 10 can be set appropriately depending on the type and size of the reel seat 11.

The cylindrical portion 10 includes an inner wall portion 2, an outer wall portion 3, a lid portion 4, a through hole 5, a vertical rib 6, and a hollow portion 7. The inner wall portion 2 has a cylindrical shape. The inner side of the inner wall portion 2 is formed with a through hole 5 extending in the axial direction. The through hole 5 is the portion into which the rod 12 described below is inserted.

The outer wall portion 3 is cylindrical. The outer wall portion 3 is formed concentrically with the inner wall portion 2 and has a larger diameter than the inner wall portion 2. The cover portion 4 is a ring-shaped, plate-shaped member that closes the space between the inner wall portion 2 and the outer wall portion 3 in the circumferential direction at one end side (rod tip side) of the fishing rod spacer 1.

As shown in Figures 4 and 5, the vertical ribs 6 connect the inner wall portion 2 and the outer wall portion 3 in the radial direction and extend linearly and plate-like in the axial direction. Multiple vertical ribs 6 are arranged at regular intervals around the circumference.

As shown in FIG. 5, the hollow portion 7 is a space defined by the inner wall portion 2, the outer wall portion 3, and a pair of vertical ribs 6, 6 adjacent in the circumferential direction. A plurality of hollow portions 7 are arranged at regular intervals in the circumferential direction. One end of the hollow portion 7 is closed by the lid portion 4, and the other end is open. In this embodiment, the hollow portion 7 has a substantially trapezoidal cross section, but may have other shapes.

As shown in Figures 1 and 2, adjacent cylindrical portions 10, 10 are each connected by three connecting portions 20. The connecting portions 20 are linear members that are rectangular in plan view. The connecting portions 20 are arranged at regular intervals in the circumferential direction. The connecting portions 20 are arranged so as to be on the inside of the outer peripheral surface of the outer wall portion 3. In other words, as shown in Figure 3, the outermost portion of the connecting portion 20, that is, the outer portion 20a, is arranged so as to be on the inside of the outer peripheral surface 3a of the outer wall portion 3. The shape and number of the connecting portions 20 can be changed as appropriate to match the shape of the reel seat 11.

Next, a method for manufacturing the fishing rod spacer 1 will be described. There are no particular limitations on the method for manufacturing the fishing rod spacer 1, but in this embodiment, it is manufactured using a 3D printer. First, molten resin is ejected from the nozzle of the 3D printer to form the lid portion 4. Next, the inner wall portion 2, outer wall portion 3, vertical rib 6 (hollow portion 7), and connecting portion 20 are stacked on the lid portion 4 at a predetermined height in a direction perpendicular to the lid portion 4. In this way, by molding the fishing rod spacer 1 while stacking it in the height direction, it can be molded in a small space. This allows many fishing rod spacers 1 to be molded at once, increasing the yield.

Next, as shown in Figures 7 to 9, a method for assembling the fishing rod spacer 1 will be described. First, as shown in Figure 7, the fishing rod spacer 1 and the reel seat 11 are assembled. The reel seat 11 is a cylindrical member for attaching and detaching a reel (not shown). The inner diameter of the reel seat 11 is formed to be slightly larger than the outer diameter of the fishing rod spacer 1. After applying adhesive to at least one of the inner peripheral surface 11a of the reel seat 11 and the outer wall portion 3 of the cylindrical portion 10, one end side (the lid portion 4 side) of the fishing rod spacer 1 is inserted into the hollow portion of the reel seat 11. In other words, it is assembled so that the lid portion 4 faces the reel seat 11.

Next, as shown in FIG. 8, the fishing rod spacer 1 and the rod 12 are assembled. The rod 12 is a cylindrical member that is the main part of the fishing rod. After applying adhesive to at least one of the inner wall 2 of the fishing rod spacer 1 and the outer circumferential surface 12a of the rod 12, the rod 12 is inserted from one end side (the cover 4 side) of the fishing rod spacer 1. In other words, the cover 4 is assembled so that it faces the rod 12. As shown in FIG. 9, the fishing rod spacer 1 is slightly shorter than the reel seat 11. In other words, when the fishing rod spacer 1 is assembled to the reel seat 11, a gap is created in the front and back. A decorative member (not shown) can be attached to this gap. Note that the fishing rod spacer 1 may be assembled to the rod 12 first, and then the reel seat 11 may be assembled later.

According to the fishing rod spacer 1 according to the present embodiment described above, the multiple cylindrical portions 10 are arranged at intervals. In other words, compared to a cylindrical spacer extending in the axial direction, the surface area of the contact between the outer circumferential surface 12a of the rod 12 and the cylindrical portions 10 is smaller, making it difficult to hinder bending of the rod 12. This makes it possible to prevent the fishing rod spacer 1 from being damaged inside the reel seat 11. In addition, since the multiple cylindrical portions 10 are connected by the connecting portions 20, when the fishing rod spacer 1 is inserted into the reel seat 11 after applying adhesive, it is possible to prevent the cylindrical portions 10 from shifting from a predetermined position inside the reel seat 11 in the axial direction of the rod, thereby improving assembly.

In addition, the cylindrical portions 10 are arranged so that the spacing between them becomes wider from the base to the tip, so that the number of cylindrical portions 10 (number per unit length) is smaller on the tip side. This makes it difficult to impede the bending of the rod 12. In other words, the fishing rod spacer 1 is more likely to follow the bending of the rod 12. On the other hand, the spacing between the cylindrical portions 10 is narrower on the base side, so that the number of cylindrical portions 10 (number per unit length) is greater. This makes it possible to increase the strength of the fishing rod spacer 1 and the reel seat 11.

The cylindrical portion 10 also includes an inner wall portion 2 that contacts the outer peripheral surface 12a of the rod 12, an outer wall portion 3 that contacts the inner peripheral surface 11a of the reel seat 11, a hollow portion 7 formed between the inner wall portion 2 and the outer wall portion 3, and a vertical rib 6 that radially connects the inner wall portion 2 and the outer wall portion 3 and extends in the axial direction. This reduces the weight of the cylindrical portion 10, and the vertical rib 6 increases the strength of the cylindrical portion 10.

Of the multiple cylindrical sections 10, the cylindrical section 10 located at the end where the rod 12 or reel seat 11 is inserted has a lid section 4 formed on the side where the rod 12 is inserted to close the hollow section 7. This prevents excess adhesive from entering the hollow section 7 and prevents the weight from increasing. In addition, when inserting the fishing rod spacer 1 into the reel seat 11, the adhesive can be inserted while being pressed by the lid section 4, so that the adhesive can be applied evenly and the adhesive strength can be increased.

The connecting portion 20 is also positioned so that the portion (outer portion 20a) farthest from the central axis in the radial direction is located inside the outer peripheral surface of the outer wall portion 3. In other words, the connecting portion 20 is positioned inside the outer wall portion 3 and is configured not to come into contact with the inner peripheral surface 11a of the reel seat 11. This makes it possible to prevent adhesive from adhering to the connecting portion 20.

Here, for example, conventional fishing rod spacers are known to be made of soft materials such as cork and EVA. The fishing rod spacer 1 of this embodiment is made of resin, so compared to these soft materials, it is easier for the vibrations of the fishing rod to be transmitted to the user of the fishing rod. In other words, by making the fishing rod spacer 1 out of resin, it is possible to improve sensitivity during actual fishing.

Although the embodiment of the present invention has been described above, appropriate design changes are possible within the scope of the present invention. For example, in this embodiment, the lid portion 4 is provided on all cylindrical portions 10, but it is sufficient that the lid portion 4 is provided on the cylindrical portion 10 located at the end where the rod 12, reel seat 11, and other mounting members are inserted. The lid portion 4 may be omitted for the other cylindrical portions 10. The lid portion 4 may be provided on both sides of the cylindrical portion 10 in the axial direction.

Second Embodiment
Next, as shown in Fig. 10, a fishing rod spacer 1A according to a second embodiment of the present invention will be described. In the fishing rod spacer 1A, the configuration of the connecting portion 20A is different from that of the first embodiment. The connecting portion 20A is a plate-like member that has a rectangular shape in a plan view, is wide in the circumferential direction, and is thin in the radial direction. The other configurations are the same as those of the first embodiment, so the description will be omitted.

The fishing rod spacer 1A according to the second embodiment can achieve substantially the same effects as the first embodiment. In addition, the connecting portion 20A can more easily follow the bending of the rod 12, making it possible to achieve a configuration that is less likely to impede the bending of the rod 12 (see FIG. 9).

Third Embodiment
Next, as shown in Fig. 11, a fishing rod spacer 1B according to a third embodiment of the present invention will be described. In the fishing rod spacer 1B, the configuration of the outer wall portion 3B is different from that of the first embodiment. A plurality of grooves 31 are formed in the outer wall portion 3B along the axial direction of the rod 12. The grooves 31 are recessed toward the inner wall portion 2. The other configurations are the same as those of the first embodiment, so a description thereof will be omitted.

The fishing rod spacer 1B according to the third embodiment can achieve substantially the same effect as the first embodiment. In addition, the groove 31 can increase the adhesive bonding strength between the inner circumferential surface 11a of the reel seat 11 (see FIG. 9) and the outer wall 3B due to the anchor effect. In this embodiment, the groove 31 is formed only in one cylindrical portion 10B (the cylindrical portion on the insertion side), but it may be formed in the other cylindrical portions 10. In this embodiment, the groove 31 is parallel to the axial direction in consideration of the flow of adhesive, but it may be extended in the circumferential direction or may be a hemispherical hole.

<Fourth embodiment>
Next, a fishing rod spacer 1C according to a fourth embodiment of the present invention will be described as shown in Figures 12 and 13. In the fishing rod spacer 1C, the configuration of the cover portion 4C is different from that of the first embodiment. In this embodiment, the differences from the first embodiment will be mainly described.

The lid portion 4C is a member that closes the space between the inner wall portion 2 and the outer wall portion 3 in the circumferential direction at one end. The lid portion 4C is ring-shaped and is configured to taper toward the rod tip. As shown in FIG. 12, the inner peripheral surface of the lid portion 4C has the same diameter as the inner peripheral surface of the inner wall portion 2. The inside of the lid portion 4C is solid. A first inclined surface 41 that tapers toward the tip is formed on the outer periphery of the lid portion 4C. The lid portion 4C may be molded integrally with the inner wall portion 2 and the outer wall portion 3, or the lid portion 4C may be made separately and then joined by welding or adhesive.

The fishing rod spacer 1C according to this embodiment can achieve substantially the same effects as the first embodiment. In addition, the lid portion 4C is formed with a first inclined surface 41 that inclines toward the outer wall portion 3. Therefore, when the fishing rod spacer 1C is attached to the reel seat 11, the adhesive can be introduced to the appropriate position by penetrating the adhesive surface along the first inclined surface 41, thereby increasing the adhesive strength. The inside of the lid portion 4C may be hollow.

Fifth Embodiment
Next, a fishing rod spacer 1D according to a fifth embodiment of the present invention will be described as shown in Fig. 14. In the fishing rod spacer 1D, the configuration of the cover portion 4D is different from that of the first embodiment. In this embodiment, the differences from the first embodiment will be mainly described.

The lid portion 4D is a portion that closes the space between the inner wall portion 2 and the outer wall portion 3 in the circumferential direction at one end. The lid portion 4D is ring-shaped. As shown in FIG. 14, a first inclined surface 51 that narrows toward the tip is formed on the outer periphery of the lid portion 4D. In other words, the first inclined surface 51 is inclined so as to move away from the axis center as it moves from the tip to the base. A second inclined surface 52 that widens toward the tip is formed on the inner periphery of the lid portion 4D. In other words, the second inclined surface 52 is inclined so as to move closer to the axis center as it moves from the tip to the base.

The fishing rod spacer 1D according to this embodiment can achieve substantially the same effect as the first embodiment. In addition, since the cover portion 4D is formed with a first inclined surface 51 inclined toward the outer wall portion 3, when the fishing rod spacer 1D is assembled to the reel seat 11 (see FIG. 9), the adhesive can be introduced to an appropriate position by penetrating the adhesive surface along the first inclined surface 51, thereby increasing the adhesive strength. In addition, since the cover portion 4D is formed with a second inclined surface 52 inclined toward the inner wall portion 2, when the fishing rod spacer 1D is assembled to the rod 12 (see FIG. 9), the adhesive can be introduced to an appropriate position by penetrating the adhesive surface along the second inclined surface 52, thereby increasing the adhesive strength. In addition, in this embodiment, the cover portion 4D is configured to have the first inclined surface 51 and the second inclined surface 52, but the first inclined surface 51 may be omitted and only the second inclined surface 52 may be configured.
