Abstract
Description
[Technical field]
[0001] The present invention relates to a fishing line guide for guiding a fishing line, and to a fishing rod equipped with a fishing line guide. [Background technology]
[0002] The fishing line guide has an annular portion with an annular guide surface that guides the fishing line. The annular guide surface is often a perfect circle. Therefore, it is difficult to keep the height of the fishing line guide, i.e., the length of the fishing line guide along the radial direction of the fishing rod body, low while still ensuring the function of smoothly guiding the fishing line, and it is also difficult to reduce the volume of the fishing line guide.
[0003] Meanwhile, the applicant has proposed a fishing line guide 200 in which the annular guide surface is non-circular in the following Patent Document 1. Specifically, as shown in Fig. 10, the annular guide surface 201 has an upper guide surface 211 that is an arc smaller than a semicircle, and a linear lower guide surface 212 that extends in the left-right direction. By making the lower guide surface 212 have a linear shape that extends in the left-right direction in this way, the upper guide surface 211 can be brought closer to the fishing rod body 300, and the height and volume of the fishing line guide 200 can be reduced.
[0004] However, the upper guide surface 211 is aligned along a virtual circle 222 centered on a virtual center 221, which is located outside the annular guide surface 201. Therefore, when the fishing line is guided by the upper guide surface 211, sliding resistance is likely to increase. Furthermore, the lower guide surface 212 is a flat surface extending in the left-right direction. Therefore, when the fishing line is guided by the lower guide surface 212, the fishing line is likely to be positioned at both left-right ends of the lower guide surface 212, which is likely to increase sliding resistance.
[0005] On the other hand, the fishing line guide in the following Patent Document 2 has a rotating collar instead of a lower guide surface. This collar is cylindrical with a central axis of rotation along the left-right direction. However, the fishing line is prone to becoming tangled in the collar and breaking. In addition, the fishing line is prone to coming off the collar to the left or right, and is easily rubbed against the end surface of the collar. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Patent No. 4023595 [Patent Document 2] Japanese Utility Model Application Publication No. 54-22096 Summary of the Invention [Problem to be solved by the invention]
[0007] An object of the present invention is to smoothly guide a fishing line while suppressing the height and volume of the fishing line guide. [Means for solving the problem]
[0008] A fishing line guide according to a first aspect of the present invention is attached to a fishing rod body. The fishing line guide includes an annular portion and an attachment portion. The annular portion has an annular guide surface. The annular guide surface guides the fishing line. The attachment portion supports the annular portion. The attachment portion extends in the axial direction of the rod body. The attachment portion is attached to the rod body. The annular guide surface has a first guide surface and a second guide surface. The first guide surface is along a first arc of a first circle. The first circle is centered on a first center and is defined by a first radius. The first center is within the annular portion. Incidentally, the first center being within the annular portion means that the first center is located inside the annular guide surface. The second guide surface is provided on the attachment portion side of the first guide surface. The second guide surface is along a second arc of a second circle. The second circle is centered on the second center and is defined by a second radius larger than the first radius.
[0009] According to this configuration, the first center is within the annular portion. Therefore, the fishing line can be smoothly guided by the first guide surface. Moreover, since the second guide surface is along the second arc and does not extend linearly in the left-right direction, the fishing line can also be smoothly guided by the second guide surface. Furthermore, since the first radius is smaller than the second radius, the height and volume of the fishing line guide can be reduced compared to when the entire annular guide surface is along the second circle.
[0010] In the fishing line guide of the second aspect according to the first aspect of the present invention, the first guide surface follows the first arc in a range exceeding 180 degrees of the first circle. With this configuration, sliding resistance between the annular guide surface and the fishing line is reduced when the fishing line is released forward.
[0011] In the fishing line guide of the third aspect according to the second aspect of the present invention, the first guide surface follows the first arc over an angle of 200 degrees or more and 240 degrees or less of the first circle. With this configuration, because the first guide surface follows the first arc over an angle of 200 degrees or more of the first circle, the sliding resistance between the annular guide surface and the fishing line when the fishing line is released forward can be further reduced. Moreover, because the first guide surface follows the first arc over an angle of 240 degrees or less of the first circle, the height and volume of the fishing line guide can be effectively reduced.
[0012] In the fishing line guide of the fourth aspect according to any one of the first to third aspects of the present invention, the first center and the second center are different from each other. With this configuration, the height and volume of the fishing line guide can be effectively reduced.
[0013] In the fishing line guide of a fifth aspect according to any one of the first to fourth aspects of the present invention, the second center is located outside the annular portion. With this configuration, the height and volume of the fishing line guide can be more effectively reduced.
[0014] In the fishing line guide of a sixth aspect according to any one of the first to fifth aspects of the present invention, the first center is located on a line segment connecting the center of the fishing rod body and the second center. With this configuration, the fishing line guide can be easily formed symmetrically, and the fishing line can be guided in a well-balanced manner.
[0015] In a fishing line guide according to any one of the first to sixth aspects of the present invention, the second radius is 1.5 to 3 times the first radius. With this configuration, the height and volume of the fishing line guide can be easily reduced.
[0016] In a fishing line guide according to any one of the first to seventh aspects of the present invention, the annular guide surface has a pair of connecting surfaces. The pair of connecting surfaces connect the first guide surface and the second guide surface. With this configuration, the provision of the pair of connecting surfaces allows the first guide surface and the second guide surface to be smoothly connected, allowing the fishing line to be smoothly guided.
[0017] In the fishing line guide of the ninth aspect according to any one of the first to eighth aspects of the present invention, the annular portion is inclined toward the rod tip. The annular guide surface is a surface along the direction in which the attachment portion extends. With this configuration, while the annular portion is inclined toward the rod tip, the annular guide surface is not a surface along the direction inclined toward the rod tip, but a surface along the direction in which the attachment portion extends, i.e., the direction in which the attachment portion extends along the axial direction of the rod body. Therefore, when the opening formed inside the annular guide surface is viewed in the axial direction of the rod body, its projected area is unlikely to become small, and a large opening area can be ensured. Therefore, the fishing line can pass through the inside of the annular guide surface with little resistance, and the casting distance can be increased, particularly when casting.
[0018] A fishing rod according to a tenth aspect of the present invention includes any one of the fishing line guides according to the first to ninth aspects described above. Effect of the Invention
[0019] As described above, the annular guide surface has a first guide surface that follows a first arc and a second guide surface that follows a second arc, so that the fishing line can be smoothly guided while reducing the height and volume of the fishing line guide.

[Figure 9] FIG. 4 is a cross-sectional view of a fishing line guide according to another embodiment of the present invention. [Figure 10] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] A fishing line guide and a fishing rod according to one embodiment of the present invention will be described below with reference to Figs. 1 to 6. The fishing line guide 1 of this embodiment is fixed at a predetermined position on the outer circumferential surface of the rod body 2. There may be various attachment methods, for example, by wound line. When wound line is used, adhesive is applied. The fishing line guide 1 is attached to various fishing rods to which a reel can be attached. The reel is, for example, a spinning reel or a dual-bearing reel. In a fishing rod to which a spinning reel is attached, the fishing line guide 1 is located on the lower side of the fishing rod when in use. Also, in a fishing rod to which a dual-bearing reel is attached, the fishing line guide 1 is located on the upper side of the fishing rod when in use. The fishing line guide 1 is preferably attached to the tip of the fishing rod as shown in Fig. 6, and is particularly preferably used in the top guide 101 located closest to the tip, the second guide counting from the tip (second guide 102), or the third guide counting from the tip (third guide 103), but may also be used in the fourth guide counting from the tip (fourth guide 104), etc. Also, it may be attached to a location other than the tip.
[0022] The fishing line guide 1 includes an annular portion 10, which is a guide portion for guiding the fishing line, and an attachment portion 11 attached to the outer peripheral surface of the fishing rod body 2. The attachment portion 11 is attached by winding the fishing line around the outer peripheral surface of the fishing rod body 2. The attachment portion 11 supports the annular portion 10. The attachment portion 11 extends in the axial direction of the fishing rod body 2. The axial direction of the fishing rod body 2 is the direction of the center 2a of the fishing rod body 2. Specifically, the attachment portion 11 extends toward the butt side of the annular portion 10. The fishing line guide 1 has a so-called single foot configuration, and the attachment portion 11 extends only toward the butt side of the annular portion 10. However, the fishing line guide 1 may have a so-called double foot configuration, in which case the attachment portion 11 extends toward both the tip side and the butt side of the annular portion 10.
[0023] The axial direction of the rod body 2 is the front-rear direction, the rod tip side is the front side and is indicated by the symbol X1, and the rod butt side is the rear side and is indicated by the symbol X2. When the fishing line guide 1 is viewed in the front-rear direction from the rear side as in Figure 3 (viewed in the front-rear direction), the circumferential direction of the rod body 2 is the left-right direction. Furthermore, the radially outer side of the rod body 2 is the upper side, and the radially inner side of the rod body 2 is the lower side.
[0024] The mounting portion 11 is in the form of a long plate extending along the front-rear direction. The lower surface 11a of the mounting portion 11 is an abutting surface that abuts against the outer circumferential surface of the fishing rod body 2. The lower surface 11a of the mounting portion 11 is preferably curved along the outer circumferential surface of the fishing rod body 2. That is, the lower surface 11a of the mounting portion 11 is preferably a curved surface that curves upward along the left-right direction. The upper surface 11b of the mounting portion 11 is a surface on the upper side opposite the lower surface 11a of the mounting portion 11. The upper surface 11b of the mounting portion 11 is preferably formed with a groove 12 extending along the left-right direction. The fishing line guide 1 can be firmly attached to the fishing rod body 2 by engaging the winding line with the groove 12.
[0025] The annular portion 10 extends upward from the front end of the mounting portion 11. The annular portion 10 may rise at a right angle to the mounting portion 11, but in this embodiment, the annular portion 10 is inclined forward with respect to the state where it rises at a right angle to the mounting portion 11. The annular portion 10 is bent upward with respect to the mounting portion 11. The annular portion 10 is inclined at an inclination angle θ of less than 90 degrees with respect to the mounting portion 11. The inclination angle θ is the rise angle of the annular portion 10 with respect to the mounting portion 11. The inclination angle θ is shown in FIG. 4. The inclination angle θ is specifically equal to or greater than 45 degrees and less than 90 degrees, and is 65 degrees in this embodiment. The annular portion 10 has a front surface 10a and a rear surface 10b, which are inclined surfaces inclined at an inclination angle θ. The annular portion 10 is generally plate-shaped.
[0026] The annular portion 10 has a symmetrical shape as shown in FIG. 3. The annular portion 10 has an annular guide surface 20 that guides the fishing line. The annular portion 10 has a guide hole 21 through which the fishing line passes. When the fishing line passes through the guide hole 21, the fishing line slides against the wall surface of the guide hole 21. The guide hole 21 penetrates the annular portion 10 in the front-rear direction. The annular guide surface 20 is provided on the wall surface of the guide hole 21. The annular guide surface 20 is the inner peripheral surface of the annular portion 10. In FIG. 4, the annular guide surface 20 is shown with a number of dots. The annular guide surface 20 is a surface along the front-rear direction. The annular guide surface 20 has an axis parallel to the center 2a of the rod body 2, and is a peripheral surface parallel to the center 2a of the rod body 2. The wall surface of the guide hole 21 is provided with the annular guide surface 20, a rear curved surface 22 adjacent to the rear side of the annular guide surface 20, and a front curved surface 23 adjacent to the front side of the annular guide surface 20. The rear curved surface 22 expands toward the rear side. The rear curved surface 22 connects the annular guide surface 20 and the rear surface 10b of the annular portion 10. The front curved surface 23 expands toward the front side. The front curved surface 23 connects the annular guide surface 20 and the front surface 10a of the annular portion 10.
[0027] The annular guide surface 20 is curved outwardly around the entire circumference as shown in Fig. 3. When viewed in the front-rear direction as shown in Fig. 3, the annular guide surface 20 is not circular but non-circular. When viewed in the front-rear direction, the annular guide surface 20 is composed of a plurality of arcs having different radii of curvature. In this embodiment, the annular guide surface 20 is composed of a first guide surface 31, a second guide surface 32, and a pair of left and right connecting surfaces 33.
[0028] FIG. 5 shows a projection view of the annular guide surface 20 as viewed in the front-rear direction. The first guide surface 31 occupies more than half of the entire circumference of the annular guide surface 20 and is a main part of the annular guide surface 20. The first guide surface 31 constitutes the upper part of the entire circumference of the annular guide surface 20. The first guide surface 31 is along the first arc 41a of the first circle 41. The first circle 41 is a circle having a first radius 41c centered on a first center 41b. The first center 41b is located inside the annular guide surface 20. The first guide surface 31 is along the first arc 41a in a range exceeding 180 degrees of the first circle 41. That is, the first guide surface 31 constitutes more than the upper half of the entire circumference of the annular guide surface 20. It is preferable that the first central angle α1 of the first arc 41a exceeds 180 degrees. It is preferable that the first guide surface 31 follows the first arc 41a in the range of 200 degrees or more and 240 degrees or less of the first circle 41. That is, it is preferable that the first central angle α1 is 200 degrees or more and 240 degrees or less. It is preferable that the first circle 41 is larger than the outer diameter of the rod body 2 at the location where the fishing line guide 1 is attached. As shown in FIG. 3, it is preferable that the first circle 41 is spaced upward from the outer circumferential surface of the rod body 2. It is also preferable that the first circle 41 is spaced upward from the upper surface 11b of the attachment portion 11.
[0029] The second guide surface 32 is located below the first guide surface 31. That is, the second guide surface 32 is located closer to the mounting portion 11 than the first guide surface 31. The first guide surface 31 is relatively far from the mounting portion 11, and the second guide surface 32 is relatively close to the mounting portion 11. The second guide surface 32 faces the lower side of the first guide surface 31. The second guide surface 32 constitutes the lower part of the entire circumference of the annular guide surface 20. The second guide surface 32 is along the second arc 42a of the second circle 42. The second circle 42 is a circle having a second radius 42c centered on the second center 42b. The second radius 42c is larger than the first radius 41c. That is, the radius of curvature of the second guide surface 32 is larger than the radius of curvature of the first guide surface 31. It is preferable that the second radius 42c is 1.5 times or more and 3 times or less than the first radius 41c.
[0030] The second center 42b is provided at a position different from the first center 41b. The second center 42b is located outside the annular guide surface 20. The second center 42b is located above the annular guide surface 20. The second center 42b is located on an extension of a line segment connecting the center 2a of the rod body 2 and the first center 41b. In other words, the first center 41b is located on a line segment L connecting the center 2a of the rod body 2 and the second center 42b. The first guide surface 31 is provided on at least the line segment L connecting the center 2a of the rod body 2 and the second center 42b, and the second guide surface 32 is provided on at least the line segment L connecting the center 2a of the rod body 2 and the second center 42b. The first center 41b is relatively close to the center 2a of the rod body 2, and the second center 42b is relatively far from the center 2a of the rod body 2. The second guide surface 32 is located inside the first circle 41 when viewed in the front-rear direction. The annular portion 10 has a symmetrical shape with respect to a plane including the line segment L.
[0031] The second guide surface 32 is aligned along the second arc 42a in a range of less than 180 degrees of the second circle 42. That is, the second guide surface 32 constitutes less than half of the entire circumference of the annular guide surface 20. The second central angle α2 of the second arc 42a is preferably less than 180 degrees, and more preferably less than 90 degrees. The second guide surface 32 is aligned along the second arc 42a in a range of 10 degrees or more and less than 90 degrees of the second circle 42. That is, the second central angle α2 is preferably 10 degrees or more and less than 90 degrees, and particularly preferably less than 45 degrees. The second central angle α2 is smaller than the first central angle α1.
[0032] The pair of connecting surfaces 33 connect the first guide surface 31 and the second guide surface 32. The pair of connecting surfaces 33 are arranged symmetrically with each other and have symmetrical shapes with each other. The connecting surfaces 33 are along the third arc 43a of the third circle 43. The third circle 43 is a circle having a third center 43b as a center and a third radius 43c. The third center 43b is located inside the annular guide surface 20. The third circle 43 is inscribed in both the first circle 41 and the second circle 42. The third radius 43c is smaller than the first radius 41c and smaller than the second radius 42c. The connecting surface 33 is along the third arc 43a in a range of less than 180 degrees of the third circle 43. The third central angle α3 of the third arc 43a is preferably less than 180 degrees, and particularly preferably less than 90 degrees. The third central angle α3 is preferably 10 degrees or more and less than 90 degrees, and is preferably 30 degrees or more and less than 90 degrees. The third central angle α3 is smaller than the first central angle α1. The third central angle α3 is preferably larger than the second central angle α2. In this embodiment, the connection surface 33 is along the third arc 43a of the third circle 43, that is, the connection surface 33 has a single curvature, but the connection surface 33 may be along multiple arcs that are different from each other, that is, the connection surface 33 may have multiple curvatures that are different from each other. The curvature of the connection surface 33 may be continuously different from the first guide surface 31 to the second guide surface 32. In the front-rear view of the annular guide surface 20 as shown in FIG. 5, the first circle 41, the second circle 42, and the third circle 43 are located on the same plane.
[0033] The annular portion 10 has an outer peripheral surface 50 that extends along the annular guide surface 20 when viewed in the front-rear direction of the fishing line guide 1 as shown in FIG. 3. When viewed in the front-rear direction, the outer peripheral surface 50 follows the first guide surface 31 (first circular arc 41a) over the entire length of the first guide surface 31. The outer peripheral surface 50 is coaxial with the first guide surface 31 and is concentric with the first center 41b. When viewed in the front-rear direction, the width dimension, which is the dimension in the inner-outer direction of the annular portion 10, is constant over the entire length of the first guide surface 31. When viewed in the front-rear direction, it is preferable that the width dimension of the annular portion 10 increases in a portion corresponding to the outer side of the connection surface 33 as it moves away from the first guide surface 31.
[0034] The annular portion 10 has a through hole 51 penetrating in the front-rear direction between the guide hole 21 and the mounting portion 11. However, the through hole 51 may be omitted. The annular portion 10 preferably has a reinforcing wall 52 connecting the rear surface 10b of the annular portion 10 and the mounting portion 11. A pair of left and right reinforcing walls 52 are provided and arranged symmetrically to each other. The reinforcing walls 52 extend from an outer position of the connection surface 33 to the mounting portion 11. The pair of left and right reinforcing walls 52 are formed so as to move away from each other toward the upper side. The reinforcing walls 52 are arranged on both the left and right sides of the through hole 51.
[0035] The fishing line guide 1 in this embodiment is made of a single member. The material of the fishing line guide 1 is arbitrary, and it may be made of metal, ceramic such as SiC, or resin such as fiber-reinforced resin. A coating having excellent sliding properties may be provided on the annular guide surface 20. Examples of the coating include a hardened layer formed by various surface treatments. The fishing line guide 1 may be made of multiple members.
[0036] As described above, since the annular guide surface 20 is noncircular and the second guide surface 32 with a large radius of curvature is provided on the mounting portion 11 side with respect to the first guide surface 31, the height and volume of the fishing line guide 1 can be easily reduced compared to when the annular guide surface 20 is circular. In addition, the distance from the rod body 2 to the annular guide surface 20, particularly the distance from the rod body 2 to the second guide surface 32, can be easily ensured. Therefore, the fishing line can be easily prevented from contacting the outer circumferential surface of the rod body 2. Furthermore, since the second guide surface 32 is a curved surface that is curved outward rather than a straight line along the left-right direction, the fishing line can be smoothly guided. Since the connection surface 33 along the third arc 43a is provided between the first guide surface 31 and the second guide surface 32, the fishing line can smoothly move between the first guide surface 31 and the second guide surface 32, and the fishing line can also be smoothly guided by the connection surface 33. In addition, the first guide surface 31 and the second guide surface 32 can be easily connected by the connecting surface 33, and the annular guide surface 20 can be formed into a smooth shape over the entire circumference.
[0037] In addition, because the annular portion 10 is inclined forward, the fishing line is less likely to become entangled in the annular portion 10. And, because the annular portion 10 is inclined forward, while the annular guide surface 20 is a parallel surface along the front-to-rear direction, the opening area of the annular guide surface 20 as viewed in the front-to-rear direction can be easily ensured, the fishing line can be smoothly inserted through the guide hole 21, and the casting distance can be increased, particularly when casting.
[0038] 7 and 8 show a fishing line guide 1 in another embodiment of the present invention. The fishing line guide 1 in this embodiment is used for a telescopic fishing rod. This fishing line guide 1 may be movable in the front-rear direction relative to the rod body 2, or may be fixed to a predetermined location on the outer circumferential surface of the rod body 2. The attachment part 11 is cylindrical with an axis along the center 2a of the rod body 2, and has an insertion hole 60 through which the rod body 2 is inserted. The attachment part 11 is a mounting tube that is attached to the rod body 2. The annular guide surface 20 is the same as that in the above embodiment. The outer shape of the annular part 10 may be concentric with the annular guide surface 20, as in the outer circumferential surface 50 shown in FIG. 3, or may be similar to the annular guide surface 20.
[0039] 9, the fishing line guide 1 may include a guide ring 3. When the fishing line guide 1 includes the guide ring 3, an inner peripheral surface 3b of the guide ring 3 becomes the annular guide surface 20. The direction of the axis 3a of the guide ring 3 may be inclined with respect to the front-to-rear direction. The direction of the axis 3a of the guide ring 3 is determined, for example, by the outer peripheral surface 3c of the guide ring 3. [Explanation of symbols]
