Problems to be solved by the invention
The subject of the invention is to extend the throw flight distance.
Technical means for solving the problems
The guide frame of the fishing line guide device according to the present invention is attached to the outer circumferential 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 annular tab has a ring mounting hole. The guide ring is mounted in the ring mounting hole. The first mounting piece is mounted on the outer circumferential surface of the fishing rod. The first support piece connects the annular piece with the first mounting piece. The second mounting piece is mounted on the outer circumferential surface of the fishing rod. The second mounting piece is located on an opposite side of the first mounting piece from the annular piece. The second support piece connects the annular piece with the second mounting piece. The first support piece is provided with a pair of arm pieces. A pair of arm pieces are respectively connected to two circumferentially spaced apart portions of the annular piece. The arm piece has a low rigidity portion between a first end portion on the first attachment piece side and a second end portion on the annular piece side. The low rigidity portion has a rigidity smaller 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 to be bent during casting, the arm piece is not easy to prop up towards the central line direction of the fishing rod, and the arm piece is easy to follow the bending of the fishing rod. On the other hand, in the arm piece, the rigidity of the first end portion, which is the end portion on the first attachment piece side, is relatively high. Therefore, the arm piece is restrained from rocking in the left-right direction at the time of casting. The right-left direction refers to a direction perpendicular to the direction of the center line 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 is a low rigidity portion in the entire length of the arm piece.
Preferably, the guide frame is made of a metal plate, and the dimension in the plate thickness direction of the low rigidity portion, that is, the thickness is thinner than the first end portion of the arm piece.
Preferably, the guide frame is made of a metal plate, and the dimension, i.e., the width, of the low-rigidity portion in a direction perpendicular to the plate thickness direction is narrower 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 above-described line guide.
ADVANTAGEOUS EFFECTS OF INVENTION
As described above, by providing the arm piece with the low rigidity portion, the support feeling of the arm piece at the time of casting can be reduced, and the arm piece can easily follow the bending of the fishing rod, thereby extending the flying distance.

Detailed Description
Hereinafter, a fishing line guide according to an embodiment of the present invention will be described with reference to fig. 1 to 10. The fishing line guide device is provided with: a guide frame 1 attached to the outer circumferential surface of a rod body 3 (see fig. 9 and 10) of a fishing rod; and a guide ring 2 mounted on the guide frame 1 for directly guiding the fishing line. In the drawing, the guide ring 2 is shown with a plurality of points. The fishing line guide is fixed to a predetermined position on the outer circumferential surface of the rod body 3 of the fishing rod by adhesion or the like. Thus, the line guide is a fixed guide. The fishing line guide is used by being attached to various types of fishing rods to which a reel can be attached, and is particularly suitable for fishing rods (poles) or road sub-rods (poles). Further, as described below, the line guide is applicable to a line guide that is positioned closest to the tail of the rod, i.e., a tail guide, among a plurality of line guides mounted on a fishing rod, but may be applied to line guides mounted at other positions.
In the following description, the direction of the center line of the fishing rod is defined as the front-rear direction, the tip side is defined as the front side, and the tail side is defined as the rear side. The radial direction of the fishing rod is set to be the up-down direction, the direction away from the outer circumferential surface of the fishing rod in the radial direction is set to be the upper side, and the direction opposite to the radial direction and approaching the outer circumferential surface of the fishing rod is set to be the lower side. The direction orthogonal to the front-rear direction and the up-down direction is referred to as the left-right direction. The right-left direction is a direction orthogonal to the front-rear direction when the outer circumferential surface of the fishing rod is viewed from the radially outer side, and is the circumferential direction of the outer circumferential surface of the fishing rod. In fig. 3 and 4, the left-right direction is indicated by an arrow X. The front-rear direction is indicated by arrows Y1 and Y2, the front side is indicated by arrow Y1, and the rear side is indicated by arrow Y2. The up-down direction is indicated by arrows Z1 and Z2, the upper side is indicated by arrow Z1, and the lower side is indicated by arrow Z2.
< 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. The guide frame 1 is thus formed from one component. The guide frame 1 is formed by punching a sheet of metal plate into a predetermined shape and bending a flat metal plate punched into a predetermined shape. The thickness of the metal plate 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 rear 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-shaped sheet 10 has a ring mounting hole 22. The guide ring 2 is mounted in the ring mounting hole 22. The first mounting piece 11 is mounted on the outer circumferential surface of the rod body 3. The second mounting piece 12 is mounted on the outer circumferential surface of the rod body 3. The first support piece 16 connects the annular piece 10 and the first mounting piece 11. The second support piece 13 connects the annular piece 10 and the second mounting piece 12.

< arm sheet 15 >)
The pair of arm pieces 15 connect two points spaced apart in the circumferential direction of the annular piece 10 to the pair of right and left side edges 51 of the standing piece 14. 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 portion as an end portion on the standing piece 14 side, and a second end portion as an end portion on the annular piece side 10. In the present embodiment, the first end is a front end 80, and the second end is a rear end 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, respectively. The pair of arm pieces 15 are bent upward with respect to the standing piece 14, that is, are bent in a valley-like shape in a plan view, with the left and right side edge portions 51 of the standing piece 14 as bending lines. As shown in fig. 3, in a side view, the pair of arm pieces 15 stand and extend while being gradually inclined toward the rear side. As in the present embodiment, the pair of arm pieces 15 are preferably curved upward in the front-rear direction in side view, but may be linear without being curved, or may be curved downward in the front-rear direction in reverse. As shown in fig. 4, the pair of arm pieces 15 extend while gradually increasing the distance therebetween toward the rear in a plan view. That is, the pair of arm pieces 15 extend rearward while expanding in a substantially V-shape in a plan view. As in the present embodiment, the pair of arm pieces 15 are preferably curved outward in the left-right direction in plan view, but may be linear without being curved, or may be curved inward in the left-right direction in the opposite direction.
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 annular piece 10. In the figure, the connection between the arm piece 15 and the ring 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 lateral direction of the entire circumference of the annular piece 10. The rear end portions of the pair of arm pieces 15 may be connected to two spaced apart portions of the outer edge portion of the annular piece 10.
The arm piece 15 has a first arm surface 82 and a second arm surface 83, a first side surface 84, and a second side surface 85. In the present embodiment, the first arm surface 82 and the second arm surface 83 are formed of opposite 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 formed by end surfaces of the metal plate. Thus, the first side 84 and the second side 85 are plate end faces. The plate 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 15 is the dimension between the first arm surface 82 and the second arm surface 83, and the width of the arm 15 is the 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 being twisted. At the front end 80 of the arm piece 15, a first arm surface 82 is connected to the upper surface 52 of the standing piece 14, and a second arm surface 83 is connected to the lower surface 53 of the standing piece 14. At the rear end 81 of the arm piece 15, a first arm surface 82 is connected to the front surface 20 of the ring piece 10, and a second arm surface 83 is connected to the rear surface 21 of the ring piece 10. The first arm surface 82 faces radially inward of the annular sheet 10 at the rear end 81. The second arm surface 83 faces radially outward of the annular piece 10 at the rear end 81.
The pair of arm pieces 15 each have 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 having a rigidity smaller than the front end portion 80 of the arm piece 15. There are various structures for setting the rigidity of the low rigidity portion to be 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 portion 90 having a width smaller 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 torsion-free state, and is a view of the arm piece 15 as seen from the first arm surface 82.
The arm piece 15 has a first wide portion 91, a narrow portion 90, and a second wide portion 92. The arm piece 15 is divided into a first wide portion 91, a narrow portion 90, and a second wide portion 92 over its entire length. 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 distal end portion 80 of the arm piece 15. The second wide portion 92 is a region near the rear end 81 of the arm piece 15. The narrow portion 90 is an intermediate region of the entire length of the arm piece 15 excluding the first wide portion 91 and the second wide portion 92. The length of each of the first wide portion 91, the second wide portion 92, and the narrow portion 90 may be varied. 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 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 more than half of the entire length of the arm piece 15, and preferably occupies most of the length. That is, the narrow portion 90 is preferably a main portion 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 or different from each other. In the present embodiment, the width W2 of the narrow portion 90 is fixed over the entire length of the narrow portion 90. However, the width W2 of the narrow portion 90 may not be fixed over the entire length of the narrow portion 90, and may be gradually narrowed 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 has the same thickness as the other parts of the guide frame 1.
< second supporting sheet 13 >)
The second support piece 13 connects the lower portion of the annular piece 10 to the front end portion 42 of the second mounting piece 12. The ring-shaped sheet 10 and the second support sheet 13 in the figure form a continuous plane. That is, the second support piece 13 is not folded in the front-rear direction with respect to the annular piece 10, but is positioned on the same surface as the annular piece 10. Further, the second support piece 13 is not curved 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 identical to 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 a substantially right angle with respect 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 being tilted forward in a range of 1 degree to 20 degrees. In addition, the second support piece 13 may be bent or curved not only in the same plane as the annular piece 10.
The second support piece 13 may have a variety of front view shapes when viewed along the center line of the ring mounting hole 22, 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 is preferably a double-leg structure including a pair of left and right support leg pieces 62. The pair of right and left support leg pieces 62 are branched and extend from a position above the front end portion 42 of the second mounting piece 12 by a predetermined distance. The distance between the pair of support legs 62 gradually increases toward the upper side. In front view, 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 portion of the second support piece 13. The through hole 63 has a substantially inverted triangle shape. The through hole 63 is defined by the left and right support leg pieces 62 and the annular piece 10. The upper end portions of the pair of support leg pieces 62 are connected to the outer edge portions of the annular piece 10. The upper end portions of the pair of support leg pieces 62 are connected at two circumferentially spaced apart positions in the lower half area of the annular piece 10. Therefore, the upper end portions of the pair of support leg pieces 62 are located further on the lower side than the rear end portions 81 of the pair of right and left arm pieces 15. As shown in fig. 7, the outer side edge portion 62a (plate end surface) of the support leg piece 62 has a tangential line or a near tangential line shape to the outer edge portion of the annular piece 10 in front view.
< guide Ring 2 >)
The guide ring 2 is typically circular in shape, but may be elliptical, oblong, or the like. In the present embodiment, the guide ring 2 is circular. The guide ring 2 has a ring main body portion 70 and a flange portion 71. The ring 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 protrudes radially outward from the outer peripheral surface of the ring body portion 70. The flange portion 71 is in contact with the annular sheet 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 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 means of adhesion.
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 piece 10, and the ring main 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 annular sheet 10. The outer diameter of the ring body 70 is substantially the same as the diameter of the ring mounting hole 22. The flange portion 71 has an outer diameter larger than the diameter of the ring mounting hole 22 and smaller than the outer diameter of the annular sheet 10 (the diameter of the outer edge portion of the annular sheet 10). Therefore, the outer peripheral surface of the flange portion 71 does not protrude radially outward from the outer edge of the annular sheet 10 and is located radially inward of the annular sheet.
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 thickness of the metal plate constituting the guide frame 1. The front surface of the guide ring 2 protrudes slightly forward from the front surface 20 of the annular piece 10, but may be substantially flush with each other. The flange portion 71 has a thickness greater than that of the annular sheet 10. The amount by which the guide ring 2 protrudes forward relative to the front surface 20 of the annular sheet 10 is smaller than the amount by which the guide ring 2 protrudes rearward relative to the rear surface 21 of the annular sheet 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 at the front end portion, which is curved inward in the radial direction in the front-rear direction. The inner peripheral surface of the guide ring 2 has a second curved surface 73 at the rear end portion, which is curved inward in the radial direction in the front-rear direction. The radius of curvature of the second curved surface 73 is larger than that 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 expands in diameter toward the rear side. The guide ring 2 may have a structure without the flange portion 71.
< installation State >)
The fishing line guide is attached to and fixed to the outer circumferential surface of the rod body 3 of the fishing rod. The mounting method uses, for example, a binding wire and an adhesive coating. In a state where the line guide is attached to the rod body 3 of the fishing rod, the front-rear directions Y1 and Y2 of the line guide are the center line direction of the rod body 3. In the attached state, the left-right direction X of the line guide is a direction orthogonal to the front-rear directions Y1, Y2 when the rod body 3 is viewed from the line guide. In the mounted state, the vertical directions Z1, Z2 of the line guide are radial directions of the rod body 3. The upper side Z1 of the fishing line guide is radially outside the rod body 3 and is in 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 circumferential surface of the rod body 3. The fishing line guide is oriented in any direction, for example, the first attachment piece 11 is located on the rod tip side with respect to the annular piece 10, and the second attachment piece 12 is located 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, facing forward. The front side Y1 of the fishing line guide is the tip side, and the rear side Y2 of the fishing line guide is the tail side. In a state where the fishing line guide is attached to the rod body 3, the guide ring 2 is in a position slightly inclined to the rod tip side. However, the center line of the guide ring 2 may be parallel to the center line of the rod body 3.
In fig. 9 and 10, the fishing line guide is shown to be positioned on the upper side of the rod body 3, but in an actual use state, the fishing line guide may be positioned on the upper side or the lower side with respect to the rod body 3, and the fishing line guide may be positioned or oriented at any position. 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 line guide is located on the underside of the rod body 3. In the case of using a double bearing reel, typically, the double bearing reel is located on the upper side of the pole body 3. In this case, the line guide is located on the upper side of the rod body 3. Thus, the 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 has the narrow portion 90 at the middle portion, the arm piece 15 does not excessively prop up at the time of casting, and easily follows the bending of the fishing rod. Thus, the flight distance extends. In particular, since the arm piece 15 has the narrow portion 90 as a main portion that occupies a large part of its length, it is excellent in following performance on bending of the fishing rod and can extend the flying distance. Further, the rigidity of the arm piece 15 can be easily reduced by the narrow portion 90, and the manufacturing is easy. On the other hand, since the first wide portion 91 is provided in the vicinity of the distal end portion 80 of the arm piece 15, rigidity in the vicinity of the distal end portion 80 of the arm piece 15 is ensured. Therefore, the rocking of the arm piece 15 in the left-right direction is suppressed. By suppressing the lateral shake of the arm piece 15, the front-back, lateral or torsional shake of the guide ring 2 is suppressed, and the drag of the fishing line at the time of casting is reduced, so that the line winding can be reduced, and the flying distance can be extended. In particular, in the present embodiment, since the standing piece 14 is provided at the joining point of the pair of right and left arm pieces 15, the rigidity of the joining point of the pair of right and left arm pieces 15 is high, and the shake of the arm pieces 15 in the right and left direction is suppressed. Further, if the standing piece 14 is bent upward in the left-right direction, the strength of the standing piece 14 becomes greater, so that it is preferable. On the other hand, the second wide portion 92 is provided near the rear end portion 81 of the arm piece 15, so that the rigidity near the connection portion of the arm piece 15 and the annular piece 10 is ensured. Therefore, the rocking of the guide ring 2 in the front-rear, left-right or torsion directions 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 wall 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 torsion-free state, in which fig. 11 (a) is a view of the arm piece 15 from the first arm surface 82 and fig. 11 (b) is a view of the arm piece 15 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 arm piece 15 is divided into a first thick portion 94, a thin portion 93, and a second thick portion 95 over its entire length. The thickness T2 of the thin portion 93 is smaller than the thickness T1 of the first thick portion 94 and the thickness T3 of the second thick portion 95. The thickness T1 of the first thick portion 94 and the thickness T3 of the second thick portion 95 may be the same or different from each other. The thickness T1 of the first thick portion 94 or the thickness T3 of the second thick portion 95 may be the same as or different from the thickness of the other portion of the guide frame 1. In the present embodiment, the thickness T2 of the thin portion 93 is fixed throughout 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 of the arm piece 15, for example.
The first thick portion 94 is a region near the distal end portion 80 of the arm piece 15. The second thick portion 95 is a region near the rear end 81 of the arm piece 15. The thin portion 93 is an intermediate region of the entire length of the arm piece 15 excluding the first thick portion 94 and the second thick portion 95. The length of each of the first thick portion 94, the second thick portion 95, and the thin portion 93 may be various. The length of the first thick portion 94 and the length of the second thick portion 95 may be equal to each other or may be 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 a length of half or more of the entire length of the arm piece 15, and preferably occupies a large part 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 fixed 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 prop up during casting, and the arm piece 15 easily follows the bending of the fishing rod and extends in the flying distance. Further, the rigidity of the arm piece 15 can be easily reduced by the thin wall portion 93. On the other hand, since the first thick portion 94 and the second thick portion 95 are provided in the vicinity of the front end portion 80 and the vicinity of the rear end portion 81 of the arm piece 15, respectively, rigidity in the vicinity of the front end portion 80 and the vicinity of the rear end portion 81 of the arm piece 15 is ensured. Therefore, the lateral shake of the arm piece 15 is suppressed, and as a result, the longitudinal, lateral or torsional shake of the guide ring 2 is suppressed, and the wire winding can be reduced, and the flight distance can be extended. The low rigidity portion may be a narrow portion 90 and a thin portion 93.
