Summary of the Invention
Problems to be Solved by the Invention
[0004] An object of the present invention is to reduce the weight of the fishing line guide and suppress the occurrence of entanglement of the fishing line in the fishing line guide.
Means for Solving the Problems
[0005] The fishing line guide according to the first aspect of the present invention is a fishing line guide attached to the rod body of a fishing rod. The fishing line guide includes an annular portion, a mounting portion, and a connecting portion. The annular portion guides the fishing line. The mounting portion is attached to the rod body. The connecting portion is provided on one side with respect to a plane including the central axis of the rod body and the central axis of the annular portion. The connecting portion connects the annular portion and the mounting portion.
[0006] The plane containing the central axis of the rod body and the central axis of the annular section shall be referred to as the reference plane. The connecting part is located on one side of the reference plane. The fishing line guide is attached to the rod body of a fishing rod used with a spinning reel. When the fishing rod is in use, the spinning reel is located on the underside of the fishing rod (rod body), and the fishing line guide is also located on the underside of the rod body, similar to the spinning reel. In this state of use, the connecting part of the fishing line guide is located on the left side of the reference plane when viewed from above. That is, the connecting part of the fishing line guide is located on the left side of the angler's hand. Therefore, "one side of the reference plane" means the left side when the rod body is viewed from above, with the fishing line guide attached to the rod body and located on the underside of the rod body.
[0007] In this configuration, the connecting section is provided on only one side relative to the reference plane. Therefore, the fishing line guide can be made lighter compared to a configuration where the connecting section is provided on both sides relative to the reference plane. The fishing line guide is preferably used as the butt guide, which is the guide closest to the spinning reel. The fishing line released from the spinning reel travels in a spiral towards the annular section of the fishing line guide. The direction of the spiral of the fishing line is clockwise when viewed from the butt end of the rod. Therefore, as the fishing line released from the spinning reel travels towards the annular section of the fishing line guide, the fishing line will hit the connecting section from the left side. Consequently, compared to a configuration where the connecting section is located on the right side relative to the reference plane, the fishing line can be effectively guided to the annular section, and while being lightweight, the occurrence of line tangling can be suppressed.
[0008] In a fishing line guide according to a second aspect of the first aspect of the present invention, the connecting portion has a first connecting end and a second connecting end. The first connecting end is connected to an annular portion. The second connecting end is connected to a mounting portion. When attached to a fishing rod, the first shortest distance is defined between the first connecting end and a reference plane. When the fishing line guide is attached to a fishing rod, the second shortest distance is defined between the second connecting end and a reference plane. The first shortest distance is longer than the second shortest distance. With this configuration, since the first shortest distance is longer than the second shortest distance, the fishing line that comes into contact with the connecting portion is guided from the second connecting end towards the first connecting end, that is, from the mounting portion towards the annular portion. Therefore, the occurrence of line entanglement at the connecting portion can be suppressed.
[0009] In the fishing line guide of the third aspect according to the first or second aspect of the present invention, the connecting portion extends at least partially in the tangential direction of the annular portion. This configuration makes it possible to suppress the occurrence of line entanglement at the connecting portion.
[0010] In the fourth aspect of the fishing line guide according to the third aspect of the present invention, the connecting portion extends tangentially to the annular portion at the first connecting end. This configuration further suppresses the occurrence of line entanglement at the connecting portion.
[0011] In the fifth fishing line guide of the present invention, which conforms to any one of the first to fourth sides, the mounting portion is provided on one side of the reference plane when attached to the rod body. With this configuration, the connecting portion extends smoothly from the mounting portion to the annular portion. Therefore, the occurrence of line entanglement at the connecting portion is suppressed.
[0012] In the sixth fishing line guide of the present invention, which conforms to any one of the first to fifth aspects, the connecting portion is provided in a linear manner. This configuration allows for further weight reduction of the fishing line guide.
[0013] The seventh side of the present invention comprises a rod body and a fishing line guide on any one of the first to sixth sides. [Effects of the Invention]
[0014] As described above, since the connecting portion is provided on one side with respect to the reference plane, the fishing line guide can be made lighter, and the occurrence of line entanglement in the fishing line guide can be suppressed. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0016] The following describes a fishing line guide and fishing rod according to one embodiment of the present invention, with reference to Figures 1 to 8. The fishing line guide 1 is fixed to a predetermined position on the outer surface of the rod body 2. The fishing line guide 1 is used in various fishing rods to which a spinning reel 6 is attached. It is particularly suitable for lightweight fishing rods used for delicate fishing with light weights or lures, such as fishing rods for area trout. The fishing line guide 1 is suitable as the fishing line guide 1 located closest to the butt of the rod among a plurality of fishing line guides 1 attached to the fishing rod, i.e., the butt guide, but it can also be applied to fishing line guides 1 attached to other positions.
[0017] The fishing line guide 1 includes a guide ring 3 and a guide frame 4. In the figure, a number of dots are shown on the guide ring 3. The guide ring 3 guides the fishing line 5. The guide frame 4 holds the guide ring 3 and is attached to the outer peripheral surface of the rod body 2. In Fig. 1 etc., a number of dots are shown on the guide ring 3. Still, taking the direction of the central axis 2a of the rod body 2 as the front-back direction, the tip side of the rod is taken as the front side and is indicated by arrow X1 in the figure, and the butt side of the rod is taken as the back side and is indicated by arrow X2 in the figure.
[0018] <The guide frame 4> The guide frame 4 is made of various materials, and in particular, it is preferably made of metal or fiber-reinforced resin. The guide frame 4 is composed of one member. In the case of being made of metal, the guide frame is composed of a single metal plate.
[0019] The guide frame 4 has a holding portion 10 that holds the guide ring 3, a mounting portion 12 that is attached to the rod body 2, and a connecting portion 11 that connects the holding portion 10 and the mounting portion 12. The holding portion 10 is preferably annular, preferably circular, and holds the guide ring 3 over its entire circumference. In this embodiment, an annular portion for guiding the fishing line 5 is formed by the holding portion 10 and the guide ring 3. In this embodiment, a plane including the central axis 2a of the rod body 2 and the central axis 3a of the guide ring 3 is defined, and this plane is taken as the reference plane 100. In this embodiment, the central axis 3a of the guide ring 3 is substantially parallel to the central axis 2a of the rod body 2, but may be inclined with respect to the central axis 2a of the rod body 2. For example, the central axis 3a of the guide ring 3 may be inclined so as to approach the central axis 2a of the rod body 2 more on the front side, that is, it may be前倾.
[0020] The connecting portion 11 is linear and has a so-called single-leg configuration. The connecting portion 11 is a support leg that supports the holding portion 10. The connecting portion 11 rises up from the mounting portion 12. Figure 2 is a view of the fishing line guide 1 from a direction perpendicular to the reference plane 100, and is a view in the direction normal to the reference plane 100. As shown in Figure 2, when viewed from the direction normal to the reference plane 100, the connecting portion 11 is curved toward the front. Near the holding portion 10, the connecting portion 11 extends in a direction perpendicular to the central axis 2a of the rod body 2, and near the mounting portion 12, it extends in the direction of the central axis 2a of the rod body 2.
[0021] The connecting portion 11, which has a single-leg configuration, is provided on only one side with respect to the reference plane 100. As described above, the fishing line guide 1 is attached to the rod body 2 of a fishing rod used with a spinning reel 6. In use, the spinning reel 6 is located below the fishing rod (rod body 2), and the fishing line guide 1 is also located below the rod body 2, similar to the spinning reel 6. In use, the connecting portion 11 of the fishing line guide 1 is located to the left of the reference plane 100 when viewed from above. That is, the connecting portion 11 of the fishing line guide 1 is located on the left side of the angler's hand. Therefore, "one side" with respect to the reference plane 100 means the left side when the rod body 2 is viewed from above with the fishing line guide 1 attached to the rod body 2 and positioned below the rod body 2. The connecting portion 11 is offset to one side with respect to the reference plane 100. Therefore, the connecting portion 11 has an asymmetrical shape. In other words, the connecting portion 11 has an asymmetrical shape with respect to the reference plane 100 in the direction normal to the reference plane 100.
[0022] The connecting portion 11 has a first connecting end 21 connected to the holding portion 10 and a second connecting end 22 connected to the mounting portion 12. The first connecting end 21 is the connection end of the connecting portion 11 to the holding portion 10, and the second connecting end 22 is the connection end of the connecting portion 11 to the mounting portion 12. The connecting portion 11 extends at least partially in the tangential direction of the holding portion 10, and more specifically, the connecting portion 11 extends in the tangential direction of the holding portion 10 at the first connecting end 21. As shown in Figure 3, when viewed in the direction of the central axis 2a of the rod body 2, the plane passing through the central axis 3a of the guide ring 3 and perpendicular to the reference plane 100 is defined as the first orthogonal plane 101. When viewed in the direction of the central axis 2a of the rod body 2, the first connecting end 21 is located in the 90-degree range on the mounting portion 12 side, between the reference plane 100 and the first orthogonal plane 101, within the entire circumference, i.e., 360 degrees, of the holding portion 10.
[0023] When the fishing line guide 1 is attached to the rod body 2, as shown in Figure 3, the distance defined between the first connecting end 21 and the reference plane 100 is defined as the first shortest distance 31, and the distance defined between the second connecting end 22 and the reference plane 100 is defined as the second shortest distance 32. The first shortest distance 31 is longer than the second shortest distance 32.
[0024] As shown in Figure 3, when viewed in the direction of the central axis 2a of the rod body 2, the connecting portion 11 has an intermediate portion 23 located between the first connecting end 21 and the second connecting end 22. The connecting portion 11 extends from the first connecting end 21 to the intermediate portion 23 so as to approach the reference plane 100, and then extends from the intermediate portion 23 to the second connecting end 22 so as to move away from the reference plane 100. In this embodiment, the intermediate portion 23 is the part that is closest to the reference plane 100. When viewed in the direction of the central axis 2a of the rod body 2, the connecting portion 11 is curved between the first connecting end 21 and the second connecting end 22 so as to approach the reference plane 100. The distance defined between the intermediate portion 23 and the reference plane 100 is called the third shortest distance 33. The third shortest distance 33 is shorter than the first shortest distance 31 and shorter than the second shortest distance 32. Note that the third shortest distance 33 may be 0. That is, the intermediate portion 23 may be in contact with the reference plane 100. Furthermore, the intermediate section 23 may be located on the other side (opposite side) beyond the reference plane 100. From the second connecting end 22 through the intermediate section 23 to the first connecting end 21, the distance may gradually move away from the reference plane 100. That is, the third shortest distance 33 may be longer than the second shortest distance 32, and the first shortest distance 31 may be longer than the third shortest distance 33. The relationship may be second shortest distance 32 ≤ third shortest distance 33 < third shortest distance 33. Also, the third shortest distance 33 may be longer than both the second shortest distance 32 and the third shortest distance 33. That is, when viewed in the direction of the central axis 2a of the rod body 2, the connecting section 11 may be curved in a direction away from the reference plane 100.
[0025] The mounting portion 12 extends from the second connecting end 22 of the connecting portion 11 in the direction of the central axis 2a of the rod body 2. More specifically, the mounting portion 12 extends from the second connecting end 22 in the direction of the central axis 2a of the rod body 2 and away from the holding portion 10. Preferably, the mounting portion 12 extends to the rear.
[0026] When the fishing line guide 1 is attached to the rod body 2, the mounting portion 12 is provided on one side of the reference plane 100. As shown in Figure 3, when viewed in the direction of the central axis 2a of the rod body 2, the plane passing through the central axis 2a of the rod body 2 and perpendicular to the reference plane 100 is defined as the second orthogonal plane 102. It is preferable that the mounting portion 12 is located on the second orthogonal plane 102.
[0027] Figure 5 shows a fishing rod in which the fishing line guide 1 is attached to the rod body 2 as a butt guide. The fishing rod is equipped with a reel seat 7. A spinning reel 6 is attached to the reel seat 7. In use, the spinning reel 6 is located below the reel seat 7 and the rod body 2.
[0028] Figures 6 to 8 show the vicinity of the fishing line guide 1 (butt guide). Figure 6 is a view of the fishing rod from the left side, Figure 7 is a view of the fishing rod from the rear in the direction of the central axis 2a of the rod body 2, and Figure 8 is a view of the fishing rod from above. The fishing line guide 1 is attached to the rod body 2 by, for example, a winding thread 8. Note that the winding thread 8 is not shown in Figure 7. The fishing line guide 1 is attached to the rod body 2 such that the attachment part 12 is located on the left side of the rod body 2. As shown in Figure 7, the reference plane 100 is aligned in the vertical direction. The attachment part 12 is located on the left side of the rod body 2, and the connecting part 11 is also located on the left side of the rod body 2. There is no connecting part 11 on the right side of the rod body 2. The connecting part 11 extends to the right and forward from the second connecting end 22 to the intermediate part 23. Therefore, in the vicinity of the second connecting end 22, the connecting part 11 extends to the right and forward along the circumferential direction of the outer surface of the rod body 2. Then, the connecting section 11 moves from the intermediate section 23 to the first connecting end 21, moving forward while also moving to the left.
[0029] In fishing, for example, when casting a rig forward, the fishing line 5 wound on the spool 6a of the spinning reel 6 is released from the spool 6a. The fishing line 5 released forward from the spool 6a moves toward the fishing line guide 1 (butt guide) in a spiral. In Figure 5, the spiraling fishing line 5 is shown by a dashed line. The direction of the spiral of the fishing line 5 is clockwise when viewed from the rear, as shown in Figure 7. Therefore, the fishing line 5 will hit the fishing line guide 1 from the left side.
[0030] In this embodiment, the fishing line guide 1 has a connecting portion 11 only on the left side with respect to the reference plane 100. Therefore, the fishing line guide 1 is lighter compared to a configuration with two connecting portions 11 on both the left and right sides, and as a result, the fishing rod is lighter. Accordingly, it is suitable for delicate fishing, such as fishing using lightweight lures like in area trout fishing.
[0031] On the other hand, the fishing line 5 released spirally from the spinning reel 6 rotates clockwise when viewed from the rear and comes into contact with the connecting portion 11 of the fishing line guide 1. Since the connecting portion 11 is provided only on the left side, the fishing line 5 can be guided to the guide ring 3 more effectively compared to a configuration where the connecting portion 11 is provided only on the right side. Therefore, the occurrence of line tangling in the fishing line guide 1 can be suppressed.
[0032] Furthermore, since the first shortest distance 31 is longer than the second shortest distance 32, the fishing line 5 that comes into contact with the connecting portion 11 is smoothly guided from the second connecting end 22 towards the first connecting end 21, that is, from the attachment portion 12 towards the holding portion 10, thereby suppressing the occurrence of line entanglement at the connecting portion 11. If the connecting portion 11 is curved from the first connecting end 21 to the second connecting end 22 so as to approach the reference plane 100, it is easy to achieve both the strength of the connecting portion 11 and the suppression of line entanglement. In particular, if the connecting portion 11 extends to the right and forward from the second connecting end 22 to the intermediate portion 23, the occurrence of line entanglement can be suppressed even further. If the connecting portion 11 extends in the tangential direction of the holding portion 10 in the vicinity of the holding portion 10, line entanglement can be easily suppressed.
[0033] Furthermore, if the mounting portion 12 is attached to the left side of the rod body 2 rather than the lower side with respect to the reference plane 100, it is easy to achieve both the suppression of line tangling and the securing of the strength of the connecting portion 11. In particular, if the mounting portion 12 is located on the second orthogonal plane 102, the shape of the connecting portion 11 becomes smoother, making it easy to achieve both the suppression of line tangling and the securing of the strength of the connecting portion 11.
[0034] Furthermore, the configuration may not include the guide ring 3. Also, the mounting portion 12 may be located, for example, on the reference plane 100.
[0035] Furthermore, a fishing line guide 1 can also be attached to a fishing rod to which a double-bearing reel is mounted. In the state of use, the double-bearing reel is located above the rod body 2, and the fishing line guide 1 is also located above it. In this case, the connecting part 11 is located to the right of the reference plane 100. Alternatively, the connecting part 11 may be located to the left of the reference plane 100.
