[Problem to be solved by the invention]

The object of the present invention is to extend the flight distance when casting. [Technical means to solve problems]

The guide frame of the fishing line guide device of the present invention is installed on the outer peripheral surface of the fishing rod. The guide frame holds the guide ring. The guide ring guides the fishing line. The guide frame includes an annular piece, a first mounting piece, a first supporting piece, a second mounting piece and a second supporting piece. The ring-shaped piece has ring mounting holes. The guide ring is installed in the ring mounting hole. The first mounting piece is mounted on the outer peripheral surface of the fishing rod. The first supporting piece connects the annular piece and the first mounting piece. The second mounting piece is mounted on the outer peripheral surface of the fishing rod. The second mounting piece is located on the opposite side to the first mounting piece relative to the annular piece. The second supporting piece connects the annular piece and the second mounting piece. The first supporting piece has a pair of arm pieces. The pair of arm pieces are respectively connected to two places separated in the circumferential direction of the annular piece. The arm piece has a low rigidity portion between the first end on the first mounting piece side and the second end on the annular piece side. The low rigidity part has less rigidity than the first end part.

According to this configuration, the arm piece has a low rigidity portion. Therefore, when the fishing rod wants to bend when casting, the arm piece cannot easily push toward the center line of the fishing rod, and the arm piece can easily follow the bending of the fishing rod. On the other hand, in the arm piece, the end portion on the first mounting piece side, that is, the first end portion, has relatively high rigidity. Therefore, the shaking of the arm piece in the left and right direction when casting is suppressed. Furthermore, the left-right direction refers to the direction orthogonal to the centerline direction of the fishing rod when the fishing line guide device is installed on the fishing rod and the fishing rod is viewed from the guide frame side.

Preferably, in the entire length of the arm piece, the main portion of the arm piece other than the vicinity of the first end and the vicinity of the second end is a low-rigidity portion.

Preferably, the guide frame is made of a metal plate, and the dimension of the low-rigidity portion in the plate thickness direction, that is, the thickness, is thinner than the first end of the arm piece.

Preferably, the guide frame is made of a metal plate, and the dimension of the low-rigidity portion in a direction orthogonal to the plate thickness direction, that is, the width, is narrower than the first end of the arm piece.

Moreover, the fishing line guide device of this invention is provided with the guide frame and the guide ring of the annular piece attached to the guide frame. Moreover, the fishing rod of this invention is equipped with the said fishing line guide device. [Effects of the invention]

As mentioned above, by providing the low-rigidity portion of the arm, the support feeling of the arm when casting can be reduced, and the arm can easily follow the bend of the fishing rod, thereby extending the flying distance.

Hereinafter, a fishing line guide device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10 .

＜Arm piece 15＞ The pair of arm pieces 15 are connected to a pair of left and right side edge portions 51 of the rising piece 14 at two locations spaced apart in the circumferential direction of the annular piece 10 . The pair of arm pieces 15 are symmetrical to each other in a plan view. The width of each arm piece 15 is narrower than the width of the first mounting piece 11 . The arm piece 15 has a first end that is an end on the rising piece 14 side and a second end that is an end on the annular piece 10 side. In this embodiment, the first end is the front end 80 and the second end is the rear end 81 .

As shown in FIG. 3 , the pair of arm pieces 15 rise and extend while gradually tilting toward the rear side when viewed from the side. The pair of arm pieces 15 are preferably curved upward in the front-rear direction in side view as in this embodiment, but they may not be curved and may be straight, or conversely, they may be curved downward in the front-rear direction. In addition, as shown in FIG. 4 , the pair of arm pieces 15 extend toward the rear side while gradually increasing the distance between them in plan view. That is, the pair of arm pieces 15 expands in a substantially V-shape when viewed from above and extends toward the rear. The pair of arm pieces 15 are preferably curved outward in the left-right direction in plan view as in this embodiment, but they may not be curved and may be straight, or conversely, they may be curved inward in the left-right direction.

The rear ends 81 of the pair of arm pieces 15 are respectively connected to the left and right sides of the outer edge of the annular piece 10 . In the figure, the connection part of the arm piece 15 and the annular piece 10 is located on the center line of the ring mounting hole 22 in the left and right direction. Therefore, the arm piece 15 is connected to the portion with the largest size in the left-right direction in the entire circumference of the annular piece 10 . Furthermore, the rear ends of the pair of arm pieces 15 only need to be connected to the outer edge of the annular piece 10 at two places apart.

The arm piece 15 has a first arm surface 82 and a second arm surface 83 , and a first side surface 84 and a second side surface 85 . In this embodiment, the first arm surface 82 and the second arm surface 83 are composed of the front and back sides of the metal plate. Therefore, the first arm surface 82 and the second arm surface 83 are plate surfaces. The first side 84 and the second side 85 are formed by the end surfaces of the metal plates. Therefore, the first side surface 84 and the second side surface 85 are plate end surfaces. The thickness direction of the metal plate of the arm piece 15 is the normal direction of the first arm surface 82 and the second arm surface 83 of the arm piece 15 . The thickness of the arm piece 15 is the dimension between the first arm surface 82 and the second arm surface 83 , and the width of the arm piece 15 is the dimension between the first side surface 84 and the second side surface 85 .

The arm piece 15 extends from the rising piece 14 to the annular piece 10 while twisting. At the front end 80 of the arm piece 15, the first arm surface 82 is connected to the upper surface 52 of the rising piece 14, and the second arm surface 83 is connected to the lower surface 53 of the rising piece 14. At the rear end 81 of the arm piece 15, the first arm surface 82 is connected to the front surface 20 of the annular piece 10, and the second arm surface 83 is connected to the rear surface 21 of the annular piece 10.

The second arm surface 83 faces the radially outer side of the annular piece 10 at the rear end portion 81 .

Each of the pair of arm pieces 15 has a low rigidity portion. The low rigidity portion is located in the middle of the entire length of the arm piece 15 . The low-rigidity portion is a portion that is less rigid than the front end portion 80 of the arm piece 15 . Various structures may be used to make the rigidity of the low-rigidity portion smaller than the rigidity of the front end portion 80 of the arm piece 15 . In this embodiment, the low-rigidity portion is a narrow-width portion 90 whose width is narrower than the front end portion 80 of the arm piece 15 . FIGS. 5 and 6 illustrate an example of the narrow portion 90 of the arm piece 15 . Furthermore, FIG. 5 is a schematic developed view showing the entire length of the arm piece 15 in a non-twisted state, and is a view of the arm piece 15 viewed from the first arm surface 82 .

The arm piece 15 has a first wide part 91 , a narrow part 90 and a second wide part 92 . The entire length of the arm piece 15 is divided into a first wide portion 91 , a narrow portion 90 and a second wide portion 92 . The width W2 of the narrow portion 90 is narrower than the width W1 of the first wide portion 91 and the width W3 of the second wide portion 92 . The first wide portion 91 is the area near the front end 80 of the arm piece 15 . The second wide portion 92 is the area near the rear end 81 of the arm piece 15 . The narrow-width portion 90 is the middle area of the entire length of the arm piece 15 except for the first wide-width portion 91 and the second wide-width portion 92 . The lengths of the first wide portion 91 , the second wide portion 92 and the narrow portion 90 may be various. The length of the first wide portion 91 and the length of the second wide portion 92 may be equal to each other or may be different from each other. The length of the narrow portion 90 is preferably longer than the length of the first wide portion 91 or the second wide portion 92 . The narrow-width portion 90 preferably occupies more than half of the total length of the arm piece 15 , and preferably occupies the majority of the length. That is, the narrow portion 90 is preferably the main part of the arm piece 15 . The width W1 of the first wide portion 91 and the width W3 of the second wide portion 92 may be the same as each other, or may be different. In this embodiment, the width W2 of the narrow-width portion 90 is fixed throughout the entire length of the narrow-width portion 90 . However, the width W2 of the narrow-width portion 90 does not have to be fixed throughout the entire length of the narrow-width portion 90 . For example, the width may be gradually narrowed toward the center of the arm piece 15 . Furthermore, the thickness T of the arm piece 15 is constant throughout the entire length. The arm piece 15 and other parts of the guide frame 1 have the same thickness.

＜Second support piece 13＞ The second supporting piece 13 connects the lower part of the annular piece 10 and the front end 42 of the second mounting piece 12 . The annular piece 10 and the second supporting piece 13 in the figure form a continuous plane. That is, the second support piece 13 is not bent in the front-rear direction with respect to the annular piece 10 but is located on the same surface as the annular piece 10 . In addition, the second support piece 13 is not bent in the front-rear direction, but is flat. Therefore, the plane constituting the annular piece 10 and the plane constituting the second support piece 13 are the same as each other. The front surface 60 of the second supporting piece 13 and the front surface 20 of the annular piece 10 are in the same plane, and the rear surface 61 of the second supporting piece 13 and the rear surface 21 of the annular piece 10 are in the same plane.

The second supporting piece 13 can rise at a bending angle of 90 degrees relative to the second mounting piece 12, but preferably rises in a state of tilting forward within a range of 1 degree to 20 degrees. Furthermore, the second supporting piece 13 is not only on the same plane as the annular piece 10, but may also be curved or deflected.

The second supporting piece 13 may have various shapes when viewed along the centerline direction of the ring mounting hole 22, but it is preferably provided with a pair of left and right supporting leg pieces 62 as in this embodiment. That is, the second support piece 13 may be configured to have only one leg of one supporting leg piece 62, but it is preferably configured to have two legs of a pair of left and right supporting leg pieces 62. The pair of left and right supporting leg pieces 62 branches and extends to the left and right from a position at a predetermined distance above the front end 42 of the second mounting piece 12 . The distance between the pair of support legs 62 gradually expands upward. When viewed from the front, the pair of support legs 62 are generally V-shaped. A through hole 63 penetrating in the front-rear direction is formed in the center of the second support piece 13 . The through hole 63 has a substantially inverted triangle shape. The through hole 63 is formed by dividing the left and right supporting leg pieces 62 and the annular piece 10 . The upper ends of the pair of supporting leg pieces 62 are connected to the outer edge of the annular piece 10 . The upper ends of the pair of supporting leg pieces 62 are connected to two circumferentially spaced locations in the lower half of the annular piece 10 . Therefore, the upper end portions of the pair of support leg pieces 62 are located lower than the rear end portions 81 of the pair of left and right arm pieces 15 . The outer side edge portion 62a (plate end surface) of the support leg piece 62 has a shape that is tangent or nearly tangent to the outer edge of the annular piece 10 when viewed from the front as shown in FIG. 7 .

＜Guide Ring 2＞ The guide ring 2 is typically in the shape of a circular ring, but may also be in an elliptical shape, an oval shape, or the like. In this embodiment, the guide ring 2 is circular. The guide ring 2 has a ring body part 70 and a flange part 71 . The ring body part 70 is cylindrical. The ring body part 70 has an inner peripheral surface and an outer peripheral surface. At least a portion of the ring body portion 70 is inserted into the ring mounting hole 22 . The flange portion 71 protrudes radially outward from the outer peripheral surface of the ring body portion 70 . The flange portion 71 is in contact with the annular piece 10 . The flange portion 71 is located at one end of the outer peripheral surface of the ring body portion 70 . The inner peripheral surface of the ring body part 70 is the inner peripheral surface of the guide ring 2 . The flange portion 71 is formed over the entire circumference. The guide ring 2 is preferably installed on the guide frame 1 by adhesion.

The outer peripheral surface of the ring body portion 70 is mounted on the wall surface of the ring mounting hole 22 . In this embodiment, the flange portion 71 is located on the rear side of the annular piece 10 , and the ring body portion 70 is inserted into the ring mounting hole 22 from the rear side. The front surface of the flange portion 71 is mounted on the rear surface 21 of the annular piece 10 . The outer diameter of the ring body portion 70 is approximately the same as the diameter of the ring mounting hole 22 . The outer diameter of the flange portion 71 is larger than the diameter of the ring mounting hole 22 and smaller than the outer diameter of the annular piece 10 (the diameter of the outer edge portion of the annular piece 10). Therefore, the outer peripheral surface of the flange portion 71 does not protrude radially outward from the outer edge portion of the annular piece 10 but is positioned radially inward.

If the dimension in the direction of the centerline of the guide ring 2 is taken as the thickness, then the thickness of the guide ring 2 is thicker than the thickness of the annular sheet 10 , which is the thickness of the metal plate constituting the guide frame 1 . Moreover, the front surface of the guide ring 2 protrudes slightly forward compared to the front surface 20 of the annular piece 10, but they may be substantially the same surface as each other. The thickness of the flange portion 71 is thicker than that of the annular piece 10 . The amount by which the guide ring 2 protrudes toward the front side relative to the front surface 20 of the annular piece 10 is smaller than the amount by which the guide ring 2 protrudes toward the rear side relative to the rear surface 21 of the annular piece 10 .

The inner peripheral surface of the guide ring 2 has a curved surface that is curved to bulge toward the center of the guide ring 2 . The inner circumferential surface of the guide ring 2 has a first curved surface 72 at the front end that is curved radially inward along the front-rear direction. The inner peripheral surface of the guide ring 2 has a second curved surface 73 at the rear end that is curved radially inward along the front-rear direction. The radius of curvature of the second curved surface 73 is greater than the radius of curvature of the first curved surface 72 . In this way, a second curved surface 73 with a larger curvature radius is formed at the rear end of the inner circumferential surface of the guide ring 2, whereby the inner circumferential surface of the guide ring 2 expands in diameter toward the rear side. Furthermore, the guide ring 2 may not have the flange part 71 .

＜Installation status＞ The fishing line guide device is installed and fixed on the outer peripheral surface of the rod body 3 of the fishing rod. The installation method is, for example, using wire binding and application of adhesive. When the fishing line guide is installed on the rod body 3 of the fishing rod, the front and rear directions Y1 and Y2 of the fishing line guide become the centerline direction of the rod body 3 . In the installed state, the left and right direction X of the fishing line guide device becomes a direction orthogonal to the front and rear directions Y1 and Y2 when the rod body 3 is viewed from the fishing line guide device. In the installed state, the up and down directions Z1 and Z2 of the fishing line guide device become the radial directions of the rod body 3 . The upper side Z1 of the fishing line guide device is radially outward of the rod body 3 and is a direction away from the outer peripheral surface of the rod body 3 . The lower side Z2 of the fishing line guide is radially inward of the rod body 3 and is in a direction approaching the outer peripheral surface of the rod body 3 . The front and rear directions of the fishing line guide device are arbitrary. For example, the first mounting piece 11 is located on the rod head side relative to the annular piece 10 , and the second mounting piece 12 is located on the rod tail side relative to the annular piece 10 . In Figures 9 and 10, facing forward, the left side is the rod head side and the right side is the rod tail side. The front side Y1 of the fishing line guide device becomes the rod head side, and the rear side Y2 of the fishing line guide device becomes the rod tail side. When the fishing line guide device is installed on the rod body 3, the guide ring 2 is in a posture slightly tilted toward the rod head side. However, the center line of the guide ring 2 can also be parallel to the center line of the rod body 3 .

Furthermore, in Figures 9 and 10, the fishing line guide device is shown to be located on the upper side of the rod body 3, but in actual use, the fishing line guide device can be located on the upper side relative to the rod body 3, or It can be located on the lower side, and the position or orientation of the fishing line guide device is arbitrary. For example, when using a spinning reel, usually the spinning reel is located below the rod body 3 . In this situation, the fishing line guide device is located on the lower side of the rod body 3 . When using a dual-bearing reel, usually the dual-bearing reel is located on the upper side of the rod body 3 . In this situation, the fishing line guide device is located on the upper side of the rod body 3 . In this way, the fishing line guide device is located in the same direction as the reel relative to the rod body 3 .

The arm piece 15 of the guide frame of the fishing line guide device has a narrow width portion 90 in the middle part, so the arm piece 15 will not be over-stretched when casting, and can easily follow the bending of the fishing rod. Therefore, the flight distance is extended. In particular, the main portion that accounts for most of the length of the arm piece 15 is the narrow portion 90, so it has excellent followability to the bending of the fishing rod and can extend the flying distance. In addition, the narrow-width portion 90 can easily reduce the rigidity of the arm piece 15, making it easy to manufacture. On the other hand, the first wide portion 91 is provided near the front end 80 of the arm piece 15, thereby ensuring the rigidity near the front end 80 of the arm piece 15. Therefore, the left and right shaking of the arm piece 15 is suppressed. By suppressing the left-right swing of the arm piece 15 and suppressing the front-rear, left-right, or torsional swing of the guide ring 2, the resistance of the fishing line during casting is reduced, the line entanglement can be reduced, and the flying distance can be extended. In particular, in this embodiment, the rising piece 14 is provided at the merging point of the pair of left and right arm pieces 15. Therefore, the rigidity of the merging point of the pair of left and right arm pieces 15 is relatively large, thereby suppressing the left-right direction of the arm piece 15. The shaking. In addition, it is preferable if the rising piece 14 is bent upward in the left-right direction because the strength of the rising piece 14 becomes greater. On the other hand, the second wide portion 92 is provided near the rear end 81 of the arm piece 15, thereby ensuring the rigidity near the connection portion between the arm piece 15 and the annular piece 10. Therefore, the guide ring 2 is suppressed from shaking in the forward and backward, left and right, or twisting directions.

In addition, in this embodiment, the narrow-width part 90 is provided as a low-rigidity part, but the structure of a low-rigidity part can be variously changed. For example, the thin-walled portion 93 may be provided as a low-rigidity portion. 11 and 12 show a structure in which a thin-walled portion 93 is provided on the arm piece 15 . Figure 11 is a schematic developed view showing the entire length of the arm piece 15 in a non-twisted state, and Figure 11(a) is a view of the arm piece 15 viewed from the first arm surface 82, and Figure 11(b) is a view of the arm piece 15 viewed from the first side surface 84. Observe the picture of arm piece 15.

The arm piece 15 has a first thick portion 94 , a thin portion 93 , and a second thick portion 95 . The entire length of the arm piece 15 is divided into a first thick-walled portion 94 , a thin-walled portion 93 , and a second thick-walled portion 95 . The thickness T2 of the thin-walled portion 93 is thinner than the thickness T1 of the first thick-walled portion 94 and the thickness T3 of the second thick-walled portion 95 . Furthermore, the thickness T1 of the first thick-walled portion 94 and the thickness T3 of the second thick-walled portion 95 may be the same as each other or may be different. In addition, the thickness T1 of the first thick-walled portion 94 or the thickness T3 of the second thick-walled portion 95 may be the same as or different from the thickness of other parts of the guide frame 1 . The thickness T2 of the thin-walled portion 93 is fixed over the entire length of the thin-walled portion 93 in this embodiment. However, the thickness T2 of the thin-walled portion 93 does not have to be fixed throughout the entire length of the thin-walled portion 93 . For example, the thickness T2 may gradually become thinner toward the center of the arm piece 15 .

The first thick-walled portion 94 is a region near the front end 80 of the arm piece 15 . The second thick wall portion 95 is a region near the rear end 81 of the arm piece 15 . The thin-walled portion 93 is the middle region of the entire length of the arm piece 15 except for the first thick-walled portion 94 and the second thick-walled portion 95 . The lengths of the first thick-walled portion 94 , the second thick-walled portion 95 and the thin-walled portion 93 may be various. The length of the first thick wall portion 94 and the length of the second thick wall portion 95 may be equal to each other or may be different from each other. The length of the thin-walled portion 93 is preferably longer than the length of the first thick-walled portion 94 or the second thick-walled portion 95 . The thin-walled portion 93 preferably occupies more than half of the total length of the arm piece 15 , and preferably occupies the majority of the length. That is, the thin-walled portion 93 is preferably the main part of the arm piece 15 . The width W of the arm piece 15 is substantially constant throughout the entire length.

If the thin-walled portion 93 is provided in the middle of the arm piece 15, the arm piece 15 will not be excessively supported when casting, and the arm piece 15 will easily follow the bending of the fishing rod, and the flying distance will be extended. In addition, the rigidity of the arm piece 15 can be easily reduced by the thin portion 93 . On the other hand, the first thick-walled portion 94 and the second thick-walled portion 95 are respectively provided near the front end 80 and the rear end 81 of the arm piece 15, thus ensuring that the arm piece 15 is protected near the front end 80 and the rear end. Rigidity near part 81. Therefore, the left and right shaking of the arm piece 15 is suppressed, and as a result, the front and rear, left and right, or torsional shaking of the guide ring 2 is suppressed, and the wire entanglement can be reduced and the flight distance can be extended. Furthermore, the low-rigidity part may be a narrow-width part 90 and a thin-walled part 93 may be used.
