Problems to be solved by the invention

The invention aims to extend the flying distance of throwing.

Means for solving the problems

The guide frame of the fishing line guide device according to the present invention is attached to the outer peripheral surface of a 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 support piece, a second mounting piece, and a second support piece. The annular sheet is provided with an annular mounting hole. 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 support 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 of the first mounting piece relative to the annular piece. The second support piece connects the annular piece and the second mounting piece. The first support piece is provided with a pair of arm pieces. The pair of arm pieces are connected to two circumferentially spaced positions of the annular piece, respectively. The arm piece has a low rigidity portion between a first end portion on the first mounting piece side and a second end portion on the annular piece side. The low rigidity portion has a rigidity lower than that of the first end portion.

According to this structure, the arm piece has a low rigidity portion. Therefore, when the fishing rod is about to bend during casting, the arm piece is not easily pushed up toward the center line direction of the fishing rod, and the arm piece is easy to follow the bending of the fishing rod. On the other hand, the arm piece has a relatively high rigidity at the first end portion, which is the end portion on the first attachment piece side. Therefore, the arm piece is restrained from swaying in the left-right direction at the time of throwing. The left-right direction is a direction perpendicular to the center line direction of the fishing rod when the fishing rod is viewed from the guide frame side in a state where the fishing line guide is attached to the fishing rod.

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

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

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

The fishing line guide device of the present invention includes a guide frame and a guide ring attached to an annular piece of the guide frame. The fishing rod according to the present invention further includes the fishing line guide device.

ADVANTAGEOUS EFFECTS OF INVENTION

As described above, by providing the arm piece with the low rigidity portion, the feeling of support of the arm piece at the time of casting can be reduced, and the arm piece easily follows the curve of the fishing rod, thereby extending the flight distance.

< guide frame 1 >

The guide frame 1 is made of metal and is integrally formed from a single metal plate. That is, the guide frame 1 is an integral frame made of a metal plate. Thus, the guide frame 1 is constituted by one member. The guide frame 1 is formed by punching a metal plate into a predetermined shape and bending a flat plate-like metal plate punched into a predetermined shape. The thickness of the metal plate to be used is, for example, about 1mm, and the plate thickness is fixed. The material is, for example, stainless steel or titanium (titanium alloy). In each part of the guide frame 1, a surface formed by the front and back surfaces of the metal plate is referred to as a plate surface, and a surface formed by cutting the metal plate, that is, an end surface is referred to as a plate end surface.

The guide frame 1 includes an annular piece 10, a first mounting piece 11, a second mounting piece 12, a first support piece 16, and a second support piece 13. The ring segment 10 has a ring mounting hole 22. The guide ring 2 is mounted in the ring mounting hole 22. The first attachment piece 11 is attached to the outer peripheral surface of the rod body 3. The second attachment piece 12 is attached to the outer peripheral surface of the rod body 3. The first support piece 16 connects the annular piece 10 and the first mounting piece 11.

< arm piece 15 >

The pair of arm pieces 15 are connected to a pair of left and right side edge portions 51 of the standing piece 14 at two positions spaced apart in the circumferential direction of the annular piece 10. The pair of arm pieces 15 are bilaterally 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 portion which is an end portion on the standing piece 14 side and a second end portion which is an end portion on the annular piece side 10. In the present embodiment, the first end portion is a front end portion 80, and the second end portion is a rear end portion 81. The front end portions 80 of the pair of arm pieces 15 are connected to the left and right side edge portions 51 of the standing piece 14. The pair of arm pieces 15 are bent upward with respect to the standing pieces 14, that is, in a valley shape in plan view, with the left and right side edge portions 51 of the standing pieces 14 as bending lines. As shown in fig. 3, the pair of arm pieces 15 extend while standing up while gradually inclining to the rear side in side view. The pair of arm pieces 15 are preferably curved upward in the front-rear direction in a side view as in the present embodiment, but may be straight without being curved, or may be curved downward in the front-rear direction in an opposite manner. As shown in fig. 4, the pair of arm pieces 15 extend while gradually increasing the distance between them toward the rear side in a plan view. That is, the pair of arm pieces 15 extend rearward while spreading in a substantially V-shape in a plan view. The pair of arm pieces 15 are preferably curved outward in the left-right direction in plan view as in the present embodiment, but may be straight without being curved, or may be curved inward in the left-right direction in an opposite manner.

The rear end portions 81 of the pair of arm pieces 15 are connected to the left and right side portions of the outer edge portion of the ring piece 10. In the figure, the joint between the arm piece 15 and the annular piece 10 is located on the center line of the ring mounting hole 22 in the left-right direction. Therefore, the arm piece 15 is connected to a portion having the largest dimension in the left-right direction in the entire circumference of the ring piece 10. The rear end portions of the pair of arm pieces 15 may be connected to two positions spaced apart from each other at the outer edge portion of the annular piece 10.

The arm piece 15 has first and second arm surfaces 82 and 83, and first and second side surfaces 84 and 85. In the present embodiment, the first arm surface 82 and the second arm surface 83 are both front and back surfaces of a metal plate. Therefore, the first arm surface 82 and the second arm surface 83 are plate surfaces. The first side surface 84 and the second side surface 85 are end surfaces of a metal plate. 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 a dimension between the first arm surface 82 and the second arm surface 83, and the width of the arm piece 15 is a dimension between the first side surface 84 and the second side surface 85.

The arm piece 15 extends from the standing piece 14 to the annular piece 10 while twisting. At the tip end 80 of the arm piece 15, the first arm surface 82 is connected to the upper surface 52 of the upright piece 14, and the second arm surface 83 is connected to the lower surface 53 of the upright 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 ring piece 10, and the second arm surface 83 is connected to the rear surface 21 of the ring piece 10. The first arm surface 82 faces the radially inner side of the annular plate 10 at the rear end portion 81. The second arm surface 83 faces the radially outer side of the annular piece 10 at the rear end portion 81.

The pair of arm pieces 15 each have a low rigidity portion. The low rigidity portion is located at a middle portion of the entire length of the arm piece 15. The low rigidity portion is a portion having rigidity lower than the front end portion 80 of the arm piece 15. There are various structures for making the rigidity of the low-rigidity portion smaller than the rigidity of the distal end portion 80 of the arm piece 15. In the present embodiment, the low rigidity portion is a narrow width portion 90 having a width narrower than the distal end portion 80 of the arm piece 15. Fig. 5 and 6 show an example of the narrow portion 90 of the arm piece 15. 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 as viewed from the first arm surface 82.

The arm piece 15 includes a first wide portion 91, a narrow portion 90, and a second wide portion 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 width portion 90 is narrower than the width W1 of the first wide width portion 91 and the width W3 of the second wide width portion 92. The first wide portion 91 is a region near the tip portion 80 of the arm piece 15. The second wide width portion 92 is a region near the rear end portion 81 of the arm piece 15. The narrow portion 90 is an intermediate region of the entire length of the arm piece 15 except for the first wide portion 91 and the second wide portion 92. The respective lengths of the first wide width portion 91, the second wide width portion 92, and the narrow width portion 90 may be various. The length of the first wide width portion 91 and the length of the second wide width portion 92 may be equal to or different from each other. The length of the narrow width portion 90 is preferably longer than the length of the first wide width portion 91 and the length of the second wide width portion 92. The narrow portion 90 preferably occupies at least half of the entire length of the arm piece 15, and preferably occupies most of the length. That is, the narrow width portion 90 is preferably a main portion of the arm piece 15. The width W1 of the first wide width part 91 and the width W3 of the second wide width part 92 may be the same as or different from each other. In the present embodiment, the width W2 of the narrow width portion 90 is fixed over the entire length of the narrow width portion 90. However, the width W2 of the narrow width portion 90 may not be fixed over the entire length of the narrow width portion 90, and may gradually decrease toward the center of the arm piece 15, for example. The thickness T of the arm piece 15 is fixed over the entire length. The arm piece 15 is the same thickness as the other portions of the guide frame 1.

< second support plate 13 >

The second support piece 13 connects the lower portion of the annular piece 10 and the distal end portion 42 of the second attachment piece 12. The ring-shaped piece 10 and the second support piece 13 form a continuous plane in the figure. That is, the second support piece 13 is not bent in the front-rear direction with respect to the annular piece 10, but is positioned on the same plane as the annular piece 10. Further, the second support piece 13 is not bent in the front-rear direction, but is planar. Therefore, the plane constituting the annular sheet 10 and the plane constituting the second support sheet 13 are the same as each other. The front surface 60 of the second support sheet 13 is coplanar with the front surface 20 of the annular sheet 10, and the rear surface 61 of the second support sheet 13 is coplanar with the rear surface 21 of the annular sheet 10. The front surface 60 and the rear surface 61 of the second supporting sheet 13 are plate surfaces. The second support piece 13 is bent upward at substantially right angles to the second attachment piece 12. The second support piece 13 may stand at a bending angle of 90 degrees with respect to the second mounting piece 12, but preferably stands in a state of falling toward the front side in a range of 1 degree to 20 degrees. The second support piece 13 may be curved or bent not only in the same plane as the annular piece 10.

The front view of the second support piece 13 when viewed along the center line direction of the ring mounting hole 22 may be variously changed, but it is preferable to provide a pair of left and right support leg pieces 62 as in the present embodiment. That is, the second support piece 13 may have a single-leg structure including only one support leg piece 62, but preferably has a double-leg structure including a pair of left and right support leg pieces 62. The pair of left and right leg pieces 62 are branched and extended left and right from the front end 42 of the second mounting piece 12 at a predetermined distance above the front end. The distance between the pair of leg pieces 62 is gradually increased toward the upper side. The pair of leg pieces 62 is substantially V-shaped in front view. 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 triangular shape. The through hole 63 is defined by the left and right leg pieces 62 and the annular piece 10. The upper ends of the pair of leg pieces 62 are connected to the outer edge of the ring piece 10. The upper ends of the pair of leg pieces 62 are connected to two circumferentially spaced positions in the lower half region of the ring piece 10. Therefore, the upper end portions of the pair of leg pieces 62 are positioned below the rear end portions 81 of the pair of left and right arm pieces 15. As shown in fig. 7, the outer side edge portion 62a (plate end surface) of the leg piece 62 has a shape that is tangential or nearly tangential to the outer edge portion of the annular piece 10 in a front view.

< guide Ring 2 >

The guide ring 2 is typically circular ring-shaped, but may be oval or oblong. In the present embodiment, the guide ring 2 has a circular shape. The guide ring 2 includes a ring body 70 and a flange 71. The ring main body 70 has a cylindrical shape. The ring body 70 has an inner peripheral surface and an outer peripheral surface. At least a portion of the ring body 70 is inserted into the ring mounting hole 22. The flange portion 71 projects radially outward from the outer peripheral surface of the ring main body portion 70. The flange portion 71 is in contact with the annular piece 10. The flange portion 71 is located at one end portion of the outer peripheral surface of the ring main body portion 70. The inner peripheral surface of the ring body 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 attached to the guide frame 1 by bonding.

The outer peripheral surface of the ring body 70 is attached to the wall surface of the ring attachment hole 22. In the present embodiment, the flange portion 71 is located on the rear side of the annular sheet 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 attached to the rear surface 21 of the ring segment 10. The outer diameter of the ring body 70 is substantially 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 of the annular piece 10 but is positioned radially inward.

If the dimension of the guide ring 2 in the center line direction is set to be a thickness, the thickness of the guide ring 2 is larger than the thickness of the annular piece 10, that is, the plate thickness of the metal plate constituting the guide frame 1. The front surfaces of the guide rings 2 protrude slightly forward from the front surface 20 of the annular piece 10, but may be substantially flush with each other. The thickness of the flange portion 71 is larger than the thickness of the annular piece 10. The amount by which the guide ring 2 protrudes forward with respect to the front surface 20 of the annular piece 10 is smaller than the amount by which the guide ring 2 protrudes rearward with respect 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 so as to bulge toward the center of the guide ring 2. The inner peripheral surface of the guide ring 2 has a first curved surface 72 curved inward in the radial direction in the front-rear direction at the front end portion. The inner peripheral surface of the guide ring 2 has a second curved surface 73 curved inward in the radial direction in the front-rear direction at the rear end portion. The second curved surface 73 has a radius of curvature greater than the radius of curvature of the first curved surface 72. By forming the second curved surface 73 having a large radius of curvature at the rear end portion of the inner peripheral surface of the guide ring 2 in this manner, the inner peripheral surface of the guide ring 2 is expanded in diameter toward the rear side. The guide ring 2 may not have the flange portion 71.

< installation State >

The fishing line guide is attached and fixed to the outer peripheral surface of a rod body 3 of a fishing rod. The mounting method is, for example, application of binding wires and adhesives. In a state where the fishing line guide is attached to the rod body 3 of the fishing rod, the front-rear directions Y1, Y2 of the fishing line guide are the center line direction of the rod body 3. In the attached state, the right-left direction X of the fishing line guide is a direction orthogonal to the front-rear directions Y1, Y2 when the rod body 3 is viewed from the fishing line guide. In the attached state, the vertical directions Z1 and Z2 of the fishing line guide are radial directions of the rod body 3. The upper side Z1 of the fishing line guide is radially outward of the rod body 3 and is directed 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 fishing line guide may be oriented in any direction, for example, the first attachment piece 11 may be positioned on the rod tip side with respect to the annular piece 10, and the second attachment piece 12 may be positioned on the rod tail side with respect to the annular piece 10. In fig. 9 and 10, the left side is the tip side and the right side is the tail side, respectively, in the forward direction. The front side Y1 of the fishing line guide is the rod tip side, and the rear side Y2 of the fishing line guide is the rod tail side. In a state where the fishing line guide is attached to the rod body 3, the guide ring 2 is slightly tilted toward the rod tip side. However, the centre line of the guide ring 2 may be parallel to the centre line of the rod body 3.

In addition, although fig. 9 and 10 show a state in which the fishing line guide is positioned above the rod body 3, the fishing line guide may be positioned above or below the rod body 3 in an actual use state, and the position or orientation of the fishing line guide may be arbitrary. For example, in the case of using a spinning reel, the spinning reel is usually located below the rod body 3. In this case, the fishing line guide is located on the lower side of the rod body 3. In the case of using a dual bearing reel, normally, the dual bearing reel is located on the upper side of the rod body 3. In this case, the fishing line guide is located above the rod body 3. Thus, the fishing line guide is positioned in the same direction as the reel with respect to the rod body 3.

Since the arm piece 15 of the guide frame of the fishing line guide device has the narrow portion 90 at the middle portion, the arm piece 15 does not excessively jack up during casting and easily follows the curve of the fishing rod. Thus, the flying distance extends. In particular, since the main portion occupying most of the length of the arm piece 15 is the narrow portion 90, the fishing rod has excellent following performance to the curve of the fishing rod, and the flying distance can be extended. Further, the rigidity of the arm piece 15 can be easily reduced by the narrow width portion 90, and the manufacturing is easy. On the other hand, since the first wide portion 91 is provided near the distal end portion 80 of the arm piece 15, the rigidity near the distal end portion 80 of the arm piece 15 is ensured. Therefore, the lateral play of the arm piece 15 is suppressed. By suppressing the lateral movement of the arm piece 15, the front-back, lateral, or twisting movement of the guide ring 2 is suppressed, and the drag of the fishing line at the time of casting is reduced, whereby the line entanglement can be reduced, and the flying distance can be extended. In particular, in the present embodiment, the standing piece 14 is provided at the confluence point between the pair of left and right arm pieces 15, so that the confluence point between the pair of left and right arm pieces 15 has high rigidity, and the lateral play of the arm pieces 15 is suppressed. It is preferable that the standing pieces 14 are bent upward in the left-right direction because the strength of the standing pieces 14 is increased. On the other hand, since the second wide portion 92 is provided near the rear end portion 81 of the arm piece 15, rigidity near the connection portion between the arm piece 15 and the annular piece 10 is ensured. Therefore, the play of the guide ring 2 in the front-rear, right-left, or twisting direction is suppressed.

In the present embodiment, the narrow portion 90 is provided as the low rigidity portion, but the structure of the low rigidity portion may be variously modified. For example, the thin portion 93 may be provided as a low rigidity portion. Fig. 11 and 12 show a structure in which the thin portion 93 is provided in the arm piece 15. Fig. 11 is a schematic developed view showing the entire length of the arm piece 15 in a non-twisted state, and fig. 11(a) is a view of the arm piece 15 viewed from the first arm surface 82, and fig. 11(b) is a view of the arm piece 15 viewed from the first side surface 84.

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 portion 94, a thin portion 93, and a second thick portion 95. The thickness T2 of the thin 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. 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 or different from each other. 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 the other portions of the guide frame 1. In the present embodiment, the thickness T2 of the thin portion 93 is fixed over the entire length of the thin portion 93. However, the thickness T2 of the thin portion 93 may not be fixed over the entire length of the thin portion 93, and may be gradually reduced toward the center portion of the arm piece 15, for example.

The first thick-walled portion 94 is a region near the tip end portion 80 of the arm piece 15. The second thick-walled portion 95 is a region near the rear end portion 81 of the arm piece 15. The thin portion 93 is an intermediate region of the entire length of the arm piece 15 except for the first thick portion 94 and the second thick portion 95. The respective 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 or different from each other. The length of the thin portion 93 is preferably longer than the length of the first thick portion 94 or the length of the second thick portion 95. The thin portion 93 preferably occupies at least half of the entire length of the arm piece 15, and preferably occupies most of the length. That is, the thin portion 93 is preferably a main portion of the arm piece 15. The width W of the arm piece 15 is substantially constant over the entire length.

If the thin portion 93 is provided in the middle of the arm piece 15 in this manner, the arm piece 15 does not excessively jack up during casting, the arm piece 15 easily follows the curve of the fishing rod, and the flight distance extends. Further, the rigidity of the arm piece 15 can be easily reduced by the thin portion 93. On the other hand, since the first thick portion 94 and the second thick portion 95 are provided near the front end portion 80 and near the rear end portion 81 of the arm piece 15, respectively, the rigidity is secured near the front end portion 80 and near the rear end portion 81 of the arm piece 15. Therefore, the lateral play of the arm piece 15 is suppressed, and as a result, the forward and backward, lateral, or torsional play of the guide ring 2 is suppressed, and the wire entanglement can be reduced, and the flying distance can be extended. The low-rigidity portion may be a narrow portion 90 and a thin portion 93.
