JP 2001-238777 A

  Therefore, an object of the present invention is to reduce the weight of the fishing line guide and to improve the attachment property to the frame.

  The present invention has been made to solve the above problems, and a fishing line guide according to the present invention includes a guide ring for guiding a fishing line and a guide frame for holding the guide ring. The guide frame is made of a hollow metal wire, and includes a frame portion that holds the guide ring, an attachment portion that is attached to the housing, and a support leg portion that connects the frame portion and the attachment portion. The mounting portion includes a flat portion in which a hollow metal wire is crushed in the vertical direction. The vertical direction is the direction that is the radial direction of the housing in the state of attachment to the housing, the direction away from the housing is the upper side, and conversely the direction that approaches the housing is the lower side.

  The fishing line guide having such a configuration can be easily reduced in weight as compared to a guide frame formed by punching a metal plate into a predetermined shape because the guide frame is formed of a hollow metal wire. The attachment part is attached to the housing by, for example, a wound thread, but since the flat part is formed in the attachment part, compared to the case where the attachment part is a shape of a hollow metal wire that is not crushed Increases adhesion to the chassis. And the winding line can be easily and firmly wound on the flat portion, and the fishing line guide can be firmly attached to the housing.

  In particular, it is preferable that a concave surface portion curved along the left-right direction is formed on the lower surface of the flat portion so that the upper side is convex. In addition, the lower surface of the flat part is a surface on the side attached to the housing. Moreover, the left-right direction is the circumferential direction of the housing and the width direction of the mounting portion. By forming the concave portion on the lower surface of the flat portion, the lower surface of the flat portion becomes easier to follow along the outer peripheral surface of the housing, and the adhesion is further increased. Therefore, the fishing line guide can be made stronger and stronger. Can be attached.

  Furthermore, it is preferable that the attachment portion is configured such that the predetermined length regions at both ends of the metal wire are aligned left and right, and a concave surface portion that is continuous in the left-right direction is formed so as to straddle the left and right metal wires. The attachment portion may be configured from a predetermined length region at one end of one metal wire, but when the predetermined length region at both ends of the metal wire is aligned left and right, the attachment portion Can be easily secured to increase the adhesion to the housing. Then, the left and right metal wires are crushed together to form a flat portion, and the concave surface portion of the lower surface of the flat portion is formed so as to straddle the left and right metal wires, so that the housing Adhesion is improved.

  The fishing rod according to the present invention is equipped with such a fishing line guide.

  Furthermore, the guide frame of the fishing line guide according to the present invention is a guide frame for holding the guide ring, which is made of a hollow metal wire, and has a frame portion for holding the guide ring and an attachment for attaching to the frame. And a support leg portion that connects the frame portion and the attachment portion, and the attachment portion includes a flat portion in which a hollow metal wire material is crushed in the vertical direction.

  In particular, the attachment portion is configured by aligning a predetermined length region at both ends of the metal wire to the left and right, and a concave surface portion curved in the left-right direction so that the upper side is convex on the lower surface of the flat portion. It is preferable to be formed so as to straddle the metal wire.

  In addition, the guide frame manufacturing method according to the present invention includes a step of arranging the predetermined length regions at both ends of the metal wire side by side and welding them together to form the attachment portion, and the width of the rear portion of the attachment portion is directed to the rear side. Cutting the left and right sides of the rear part of the mounting part so as to be narrow, pressing the metal wire material in the rear part of the mounting part in the vertical direction to form a flat part, and pressing the flat part up and down Forming a concave surface portion on the lower surface of the flat portion by bending and deforming. It should be noted that the left and right sides of the rear portion of the mounting portion are cut so that the width of the rear portion of the mounting portion becomes narrower toward the rear side, and the metal wire material in the rear portion of the mounting portion is crushed in the vertical direction to form a flat portion. May be performed simultaneously, or after the step of crushing the metal wire at the rear part of the attachment part in the vertical direction to form the flat part, the width of the rear part of the attachment part is narrower toward the rear side. You may perform the process of excising the right-and-left both sides of the rear part of an attaching part so that it may become. That is, the left and right side portions of the flat portion may be excised. The tip side is the front side and the buttock side is the rear side. Therefore, the rear part of the attachment part is a part on the buttock side of the attachment part.

  As described above, since the guide frame is made of a hollow metal wire, it can be reduced in weight as compared to a guide frame punched out of a metal plate, and a flat portion is formed in the mounting portion of the guide frame. So it can be attached to the housing with good adhesion.

  Hereinafter, a fishing line guide according to an embodiment of the present invention will be described with reference to FIGS. The fishing line guide 1 in this embodiment is a guide ring 2 for directly guiding a fishing line, and holds the guide ring 2 and connects the guide ring 2 and the frame 5 as shown in FIGS. A guide frame 3 and a bridge part 4 for reinforcing the guide frame 3 are provided.

  In the drawing, the axial direction of the casing 5 is referred to as the front-rear direction, the tip side (front side) is indicated by reference numeral X1, and the buttock side (rear side) is indicated by reference numeral X2. A direction perpendicular to the axial direction of the housing 5 and passing through the center line 50 of the guide ring 2 is a vertical direction, and a direction away from the housing 5 is an upper side, which is indicated by Z1. The direction approaching is indicated by Z2 with the lower side as the lower side. The upper side may be referred to as the distal end side, and the lower side may be referred to as the proximal end side. Moreover, the direction orthogonal to the axial direction of the housing 5 in the plan view seen from the upper side is defined as the left-right direction, which is indicated by the symbol Y. The axial direction (front-rear direction) of the housing 5 is the direction of the center line 51 of the housing 5 and is the longitudinal direction of the mounting portion 32 of the guide frame 3 described later, and the left-right direction is the short side of the mounting portion 32. Direction (width direction).

<Guide ring 2>
The guide ring 2 is, for example, a circular ring as shown in FIG. 1, but may be an ellipse or an oval. In the present embodiment, the case where the guide ring 2 is circular will be described. The guide ring 2 is made of various hard materials having excellent wear resistance. For example, a ceramic typified by SiC (silicon carbide) may be used, but in the present embodiment, the guide ring 2 is made of titanium. Titanium alloy is preferable as titanium. Titanium alloy is a mixture of α phase and β phase, and is mainly α phase and a near α type (α alloy with a small amount of β stabilizing element added) in which β phase remains in part, α + β type and β type are preferred. In particular, a β-type titanium alloy is preferable, the cold workability is good, and the strength of the member can be easily secured. Examples of the near α type include Ti-8Al-1Mo-1V and Ti-6Al-2Nb-1Ta-0.8Mo. The α + β type has a larger amount of β phase remaining than the near α type, such as Ti-3Al-2.5V and Ti-6Al-4V. The β type is also called a metastable β type, and has more β stabilizing elements and fewer α stabilizing elements than the α + β type. In the β type, the α phase is dispersed and formed in fine grains in the residual β phase. Therefore, the α phase and the β phase are present in a mottled pattern on the surface of the β type. . Examples of β-type include Ti-15V-3Cr-3Sn-3Al, Ti-3Al-8V-6Cr-4Zr-4Mo, Ti-10V-2Fe-3Al, etc. Ti-15V-3Cr-3Sn-3Al is preferable because it is excellent.

  The guide ring 2 has a thread insertion hole through which the fishing line is inserted, and guides the fishing line directly by sliding the fishing line on the inner peripheral surface 2 a of the guide ring 2. As shown in FIGS. 9B and 11, the inner peripheral surface 2a of the guide ring 2 is a curved surface curved in the front-rear direction so as to be inwardly convex (center side convex) in a sectional view. The outer peripheral surface 2b of the guide ring 2 is also a curved surface curved in the front-rear direction so as to be inwardly convex (center side convex) in a sectional view. That is, the guide ring 2 has a convex inner peripheral surface 2a that is curved in an arc shape so as to be convex toward the center and a curved shape that is curved in an arc shape so as to be convex on the center side in a cross-sectional view cut in the direction of the center line 50. And a concave outer peripheral surface 2b. The inner peripheral surface 2a and the outer peripheral surface 2b of the guide ring 2 have shapes corresponding to each other. The guide ring 2 is made of a bent thin metal plate, and the front and back surfaces of the metal plate are an inner peripheral surface 2a and an outer peripheral surface 2b, respectively.

  More specifically, the guide ring 2 includes annular flanges 22 and 23 that protrude radially outward at both ends in the direction of the center line 50, that is, both front and rear ends. By forming the flanges 22 and 23 at the front and rear ends, respectively, the outer peripheral surface 2b of the guide ring 2 is formed with a concave circumferential groove 20 between the flanges 22 and 23 over the entire circumference. become. The outer peripheral surface 2b of the guide ring 2 is curved in a centrally convex arc shape as a whole in a cross-sectional view. . That is, the cross-sectional shape of the circumferential groove 20 is a curved surface. The diameters G3 and G4 of the front and rear flange portions 22 and 23 are both larger than the inner diameter D of the frame portion 30 of the guide frame 3 described later (the diameter at the apex that is the smallest diameter portion of the inner peripheral surface of the frame portion 30). . The diameters G3 and G4 of the front and rear collars 22 and 23 may be the same, but one diameter G4 is preferably smaller than the other diameter G3. In this embodiment, the diameter of the front collar 23 is G4 is smaller than the diameter G3 of the collar portion 22 on the rear side. The diameter G4 of the front flange 23 is the outer diameter of the front end of the guide ring 2, and the diameter G3 of the rear flange 22 is the outer diameter of the rear end of the guide ring 2.

  As will be described later, the frame portion 30 of the guide frame 3 and the bridge part 4 are engaged with the circumferential groove 20 of the outer peripheral surface 2 b of the guide ring 2. The guide frame 3 is made of a metal wire having a circular cross section, and an angular range of 90 degrees or more and less than 180 degrees of the entire circumference of the circular section is preferably engaged with the circumferential groove 20 of the outer peripheral surface 2 b of the guide ring 2. Further, as shown in FIG. 9B, the thickness G1 of the guide ring 2 in the radial direction (inner and outer directions) is equal to the outer diameter of the guide ring 2 (the diameter G3 of the rear flange portion 22 which is the larger one). Although it is a difference in inner diameter, the thickness is constant over the entire circumference. The radial thickness G1 of the guide ring 2 is smaller than the dimension G2 (length) along the direction of the center line 50 of the guide ring 2.

  The guide ring 2 is formed by pressing a metal plate into a predetermined shape. As shown in FIG. 8, for example, a metal plate made of a titanium alloy is punched into a donut shape, and the punched donut-shaped metal plate 21 is indicated by an arrow from one of the front and back surfaces as shown in FIG. Then, one end portion of the cylindrical metal plate 21 is curved in a hook shape radially outward to form a flange portion 22. Next, as shown by the arrow from the other surface side which is the opposite side as shown in FIG. 9B, the cylindrical metal plate 21 is further pressed, and the other end portion is also radially outward like the one end portion. The flange portion 23 is formed by curving in a hook shape, and the guide ring 2 is formed as a cross-sectional shape having a cross-sectional arc shape in which the cross-sectional shape of the cylindrical metal plate 21 is curved in a convex manner toward the center.

  In addition, the magnitude | size of the curve of the other end part of the metal plate 21 is smaller than that of the one end part, that is, the magnitude of the curve of the other end part of the guide ring 2 is smaller than that of the one end part. Therefore, the outer diameter of the guide ring 2 is larger at one end than at the other end. The guide ring 2 formed in this way has a shape having annular flanges 22 and 23 protruding outward in the radial direction at both ends, and the guide frame 3 between the flanges 22 and 23. Engage. Specifically, as shown in FIGS. 2 and 3, one end portion having a relatively large degree of bending outward in the radial direction is the rear side (rear end portion), and the degree of bending outward in the radial direction is relatively small. The other end portion is attached to the guide frame 3 so as to be the front side (front end portion). The guide ring 2 has flanges 22 and 23 formed at both ends thereof, and a circumferential groove 20 is formed between the flanges 22 and 23, and the guide frame 3 is engaged with the circumferential groove 20. The movement is restricted by the circumferential groove 20 or the front and rear flanges 22 and 23 and is prevented from falling off to the front side or the rear side. In particular, since the outer peripheral surface 2b of the guide ring 2 including both the flange portions 22 and 23 is formed in a sectional view arc shape with a convex on the center side, the relationship with the frame portion 30 of the guide frame 3 made of a metal wire having a circular cross section. The combined state is stable, and the back and forth movement of the guide ring 2 can be reliably controlled.

  In addition, although the outer peripheral surface 2b of the guide ring 2 and the frame part 30 of the guide frame 3 may be in surface contact in a sectional view cut in the radial direction, they may be in point contact. The guide frame 3 is a metal wire having a circular cross section, but when the outer peripheral surface 2b of the guide ring 2 and the guide frame 3 are in point contact with each other, the guide frame 3 is spaced from one point to the back (circumferential direction of the circular cross section of the metal wire). It is preferable that the contact is made at a plurality of points, and contact at two or three points is more preferable.

<Guide frame 3>
The guide frame 3 is mounted on the outer peripheral surface of the housing 5 and rises upward from the mounting portion 32, that is, away from the housing 5 in the radial direction. A frame main body for holding the guide ring 2 at a distant position. The frame body portion includes a frame portion 30 that holds the guide ring 2, and support leg portions 31 that connect the frame portion 30 and the attachment portion 32. That is, the frame main body portion includes a frame portion 30 on the distal end side (upper side) and a support leg portion 31 on the proximal end side (lower side).

  The guide frame 3 is composed of a metal wire. Specifically, the guide frame 3 is formed by bending a single metal wire into a U shape along the outer peripheral surface 2 b of the guide ring 2. The metal wire is made of, for example, a titanium alloy, stainless steel, or aluminum alloy. Among these, a titanium alloy is particularly preferable from the viewpoint of weight reduction. The details of the titanium alloy are the same as those of the guide ring 2, and since the cold workability is good and the strength of the member can be easily secured, a β-type titanium alloy is preferable. The metal wire has a circular cross-sectional shape. The metal wire is preferably a hollow wire, i.e., a linear pipe material, from the viewpoint of achieving both weight reduction and strength and easily securing a contact area with the guide ring 2. The wire diameter (outer diameter) of the metal wire is, for example, 0.3 to 6 mm, preferably 1 to 3 mm.

  The guide frame 3 is formed by bending a single hollow metal wire. The shape of the guide frame 3 is U-shaped in a rear view as shown in FIGS. 2 and 4 or a front view as viewed from the front side. In this embodiment, both ends of the metal wire are aligned in one direction. Thus, in this embodiment, since the guide frame 3 is configured by bending one metal wire into a U shape as a whole, the support leg portion 31 and the attachment portion 32 are each provided with two metal wires on the left and right. It has a two-legged configuration. Note that the left and right feet are symmetrical.

  Further, as shown in FIGS. 3 and 5, the frame main body portion extends from the front end portion of the attachment portion 32 to the upper side while being curved and then linearly extends upward. The portions of the frame main body that are curved and directed upward are a root region 31c and an intermediate region 31b of the support leg 31 described later. In this embodiment, the frame main body portion finally rises at a right angle with respect to the mounting portion 32, and therefore the center line 50 of the guide ring 2 is parallel to the center line 51 of the housing 5. However, the frame main body may rise so that the center line 50 of the guide ring 2 is not parallel to the center line 51 of the housing 5 but is inclined. That is, a configuration in which the frame main body portion stands up in a forward inclined posture may be used.

<Frame part 30>
The frame portion 30 is a portion for holding the guide ring 2 inside thereof, constitutes a region on the tip side of the frame main body portion, and is formed in an arc shape having a predetermined center angle θ. The frame portion 30 is formed in a C-shape that opens downward by bending a metal wire along the outer peripheral surface of the guide ring 2. The frame portion 30 has a size and shape corresponding to the guide ring 2. The shape of the frame portion 30 differs depending on the shape of the guide ring 2. In this embodiment, since the circular guide ring 2 is used, the frame portion 30 has a corresponding arc shape. When used, the frame 30 also has an elliptical arc shape correspondingly. The frame part 30 supports only the outer peripheral surface 2 b of the guide ring 2 by circling only the upper predetermined range of the entire circumference of the guide ring 2.

  The frame portion 30 circulates within a predetermined angle range of the guide ring 2. As shown in FIG. 4, the central angle θ of the frame portion 30 is preferably an angle in the vicinity of 180 degrees, and is 150 degrees to 240 degrees. In particular, it is more preferably 160 to 200 degrees. In the present embodiment, the central angle θ of the frame portion 30 is an angle slightly exceeding the half circumference of the guide ring 2. In FIG. 4, a virtual circle 52 obtained by extending the inner peripheral surface of the frame portion 30 is indicated by a two-dot chain line. The virtual circle 52 is a circle when the inner peripheral surface of the frame portion 30 is extended to 360 degrees in the circumferential direction and the inner peripheral surface of 360 degrees is viewed in the direction of the center line 50 of the guide ring 2. The diameter D of the virtual circle 52 is the inner diameter D of the frame portion 30 (the diameter at the apex that is the smallest diameter portion of the inner peripheral surface of the frame portion 30). Further, in FIG. 4, a tangent line 53 that starts from the lower end portion (end portion on the base side) of the support leg portion 31 and contacts the virtual circle 52 is indicated by a two-dot chain line. The tangent line 53 is a tangent line drawn toward the virtual circle 52 from the inner surface in the left-right direction at the lower end of the support leg 31 when the fishing line guide 1 is viewed in the direction of the center line 50 of the guide ring 2. . The central angle θ of the frame portion 30 is preferably smaller than the central angle α on the front side, which is the central angle between the contact points 54 at which the two tangent lines 53 are in contact with the virtual circle 52 and away from the attachment portion 32. .

<Support leg 31>
The support leg portion 31 is located between the frame portion 30 and the attachment portion 32 and connects the frame portion 30 and the attachment portion 32. As shown in FIG. 4, the support leg 31 has a two-legged configuration in which two support legs 31 are arranged on the left and right. First, the shape of the support leg 31 in a front view when viewed from the front side or a rear view when viewed from the rear side will be described. The pair of left and right support legs 31 are symmetrical to each other. The pair of left and right support leg portions 31 respectively extend downward from both ends in the circumferential direction of the frame portion 30 and are V-shaped as a whole in a front view or a back view. More specifically, the pair of left and right support leg portions 31 has a curved shape so as to swell outward in the left-right direction. The pair of left and right support leg portions 31 extend downward from both ends of the frame portion 30 so as to bulge outward in the left-right direction, and then approach each other, i.e., narrow in the left-right direction. It extends toward the inside and is in contact with each other at the lower end. However, the lower end portions of the pair of left and right support leg portions 31 may be in a state of approaching each other with a slight gap. The central angle θ of the frame portion 30 is equal to the central angle α between the contact points 54 at which the tangent line 53 contacts the virtual circle 52 and away from the attachment portion 32, and along the tangent line 53. The support leg 31 can also be formed in a straight line, but the center angle θ of the frame 30 is the center angle between the contacts 54 where the tangent 53 contacts the virtual circle 52 and away from the mounting portion 32. It is effective in preventing yarn entanglement if it is made smaller than a certain center angle α on the front side and the shape of the support leg 31 in front view or rear view is a curved shape bulging outward with respect to the tangent line 53.

  The pair of left and right support leg portions 31 have curved shapes that swell outward in the left-right direction. However, in this embodiment, the center angle θ of the frame portion 30 is 180 degrees or more. The maximum separation distance between 31 is equal to the inner diameter D of the frame portion 30. That is, the diameter D of the virtual circle 52 in FIG. 4 and the maximum separation distance between the both support legs 31 are equal. Further, in the present embodiment, the pair of left and right support leg portions 31 are in contact with each other at the lower end portion, so that the separation interval between the lower end portions of the pair of left and right support leg portions 31 is zero. The central angle θ of the frame portion 30 is less than 180 degrees, and the left and right support leg portions 31 have curved shapes that swell outward in the left-right direction, and the maximum separation distance between the support leg portions 31 is The inner diameter D of the frame portion 30 may be larger.

  Next, the shape of the support leg 31 in a side view when viewed from the left and right directions as shown in FIGS. 3 and 5 will be described. The support leg 31 can be divided into three regions. That is, the support leg 31 includes a tip region 31a close to the frame portion 30, a root region 31c close to the attachment portion 32, and an intermediate region 31b that is a portion between the tip region 31a and the root region 31c. Yes. The tip region 31 a of the support leg portion 31 extends downward from the circumferential end of the frame portion 30 without being bent in the front-rear direction, and is on the same plane as the frame portion 30. That is, the tip region 31a of the support leg 31 is located on a plane orthogonal to the center line of the frame 30 (center line 50 of the guide ring 2). Each of the intermediate region 31b and the root region 31c of the support leg 31 has a curved shape curved in the front-rear direction. Therefore, the intermediate region 31 b and the base region 31 c of the support leg 31 are not located on the same plane as the frame 30 and the tip region 31 a of the support leg 31. The intermediate region 31b of the support leg 31 extends downward from the lower end of the tip region 31a of the support leg 31 while curving backward. The degree of bending in the front-rear direction in the intermediate region 31 b of the support leg 31 is gentler than the degree of bending in the front-rear direction in the root region 31 c of the support leg 31. The base region 31 c of the support leg 31 extends downward while curving backward from the lower end of the intermediate region 31 b of the support leg 31 to the front end of the mounting portion 32. The degree of bending in the front-rear direction in the base region 31c of the support leg 31 is tighter than that in the intermediate region 31b of the support leg 31, and the radius of curvature is relatively small, but the metal wire is crushed in the base region 31c. The cross-sectional shape is maintained without any problems. That is, the degree of bending in the front-rear direction in the root region 31c of the support leg 31 is such that the metal wire is not crushed in the radial direction by the bending in the front-rear direction, and the curvature radius of the bending in the front-rear direction is that of the metal wire. The curvature radius is small enough not to be crushed in the radial direction. Thus, the metal wire in the support leg 31 maintains a circular cross section over the entire region including the root region 31c.

<Mounting part 32>
The attachment portion 32 extends in a straight line in plan view from the lower end portion of the support leg portion 31 toward the rear side (buttock side). In the present embodiment, the attachment portion 32 has a two-leg configuration composed of a predetermined length region at both ends of one metal wire. That is, the attachment portion 32 is configured by a pair of left and right linear bodies each having a predetermined length region at both ends of a single metal wire arranged in parallel in the left and right directions without any space therebetween. It extends from the lower end of the portion 31 to the rear side. The pair of left and right linear bodies are joined together and integrated. The joining method is arbitrary, but preferably by welding.

  The attachment portion 32 is composed of three regions whose thickness is not constant over the entire length but different in thickness. That is, the mounting portion 32 is positioned between the straight portion 32a having a circular cross section located on the front side, the plate-like flat portion 32c located on the rear side, and the straight portion 32a and the flat portion 32c, and facing the rear side. The taper portion 32b gradually decreases in thickness (dimension in the vertical direction). The straight portion 32 a constitutes the front portion of the attachment portion 32 and extends rearward from the root region 31 c of the support leg portion 31. The straight portion 32a is a portion where a hollow metal wire maintains its circular cross-sectional shape. The straight portion 32a is not curved in the front-rear direction and extends linearly along the front-rear direction. The taper portion 32b constitutes an intermediate portion of the mounting portion 32, and the upper surface thereof is gradually inclined downward toward the rear side, and the thickness thereof decreases toward the rear side due to the downward inclination of the upper surface. ing. The tapered portion 32b is a portion where the hollow metal wire is compressed in the vertical direction and the amount of compression gradually increases toward the rear side, and is connected to the flat portion 32c at the rear end. The flat portion 32c constitutes the rear portion of the attachment portion 32, and is a portion in which a hollow metal wire is crushed in the vertical direction to form a plate shape.

  In addition, although the width | variety (dimension in the left-right direction) of the attachment part 32 may be constant, it is preferable to make it narrow gradually toward the rear side as shown in FIG. Specifically, the straight portion 32a and the tapered portion 32b have a constant width, and the flat portion 32c is gradually narrowed toward the rear side. The left and right side portions of the flat portion 32c are cut out at predetermined portions so that the width of the flat portion 32c gradually decreases toward the rear side. In FIG. 6, the shape before being cut is indicated by a two-dot chain line.

  On the lower surface of the flat portion 32c, a concave portion 38 is formed that is curved along the left-right direction so that the upper side is convex as shown in FIG. As described above, the mounting portion 32 is configured by aligning a pair of left and right linear bodies in parallel in the left-right direction. It has become. Note that the upper surface of the flat portion 32c is curved in the left-right direction so as to be convex upward corresponding to the concave surface portion 38 formed on the lower surface. It is a convex curved surface curved in the direction, and the lower surface of the flat portion 32c is a concave curved surface curved in the left-right direction. The curved shape of the flat portion 32c is formed by crushing a hollow metal wire in the vertical direction into a plate shape and further bending and deforming the plate-shaped flat portion 32c. The concave surface portion 38 is preferably shaped along the circumferential curved surface of the outer peripheral surface of the housing 5. The curvature radius R (see FIGS. 4 and 7) of the concave portion 38 is, for example, the curvature radius of the outer peripheral surface of the housing 5 (1/2 of the outer diameter of the housing 5).

  The attachment portion 32 is wound around the outer peripheral surface of the housing 5 by the winding thread 6 as shown in FIG. 2, but to prevent the attachment portion 32 from coming off from the housing 5, A notch (not shown) may be provided. When the notch portions are provided on the left and right side portions of the attachment portion 32 in this way, the wound yarn 6 is wound more firmly in the notch portions.

  First, the guide frame 3 is formed by bending one metal wire into a U-shape and curving it in the front-rear direction so that the predetermined length regions at both ends of the metal wire are aligned on the left and right. Next, the predetermined length regions at both ends of the metal wires arranged on the left and right are welded and integrated to form the attachment portion 32. Next, the metal wire at the rear portion of the attachment portion 32 is crushed in the vertical direction to form the flat portion 32c, and at the same time, the left and right side portions of the flat portion 32c are cut obliquely. In addition, after forming the flat part 32c, you may make it cut off the right-and-left both sides of the flat part 32c by another process. And the formed flat part 32c is further pressed up and down, the flat part 32c is curvedly deformed along the left-right direction, and the concave-surface part 38 is formed in the lower surface of the flat part 32c. Thus, the flat part 32c integrated with the lower surface of the metal wire on either side can be formed by forming the flat part 32c after joining the predetermined area | region of the both ends of a metal wire. Moreover, the concave surface part 38 continued in the left-right direction can be formed so as to straddle the left and right metal wires by subsequently deforming the flat part 32c.

<Bridge parts 4>
As described above, the frame portion 30 has a C-shape opening downward, and the support leg portion 31 has a pair of left and right two legs and is separated from the left and right. Further, the frame portion 30 abuts and supports only the upper predetermined angle region of the outer peripheral surface 2 b of the guide ring 2, and the lower predetermined angle region of the outer peripheral surface 2 b of the guide ring 2 contacts the guide frame 3. Not supported. Therefore, in order to reinforce the guide frame 3 and complement the holding of the guide ring 2 by the guide frame 3, a bridge part 4 is provided at a position below the guide ring 2.

  The bridge part 4 is located on the inner side of the guide frame 3 and on the side of the attachment portion 32 with respect to the guide ring 2 (the side close to the casing 5 when mounted on the casing 5). The bridge part 4 is in contact with the lower predetermined angle region of the outer peripheral surface 2b of the guide ring 2 to hold the lower predetermined angle region of the outer peripheral surface 2b of the guide ring 2, and the pair of left and right support legs 31 Are connected to the left and right. Specifically, the bridge part 4 connects the support legs 31 to each other within the range of the tip area 31 a among the entire areas of the support legs 31. That is, it is preferable that the bridge part 4 connects the front region 31a instead of the intermediate region 31b of the support leg 31. The bridge part 4 connects the pair of left and right support legs 31 to the left and right to function as a projecting part, whereby the guide frame 3 is reinforced, and the vicinity of the opening of the frame part 30 of the guide frame 3 is connected by the bridge part 4. It will also be. Further, the bridge part 4 supports most of the angular region where the guide frame 3 does not support the guide ring 2, and increases the holding force of the guide ring 2. Therefore, the guide ring 2 is held so as to be sandwiched up and down by the frame portion 30 of the guide frame 3 and the bridge part 4.

  The bridge part 4 compensates for the space between the guide frame 3 and the guide ring 2 at two left and right positions where the guide frame 3 moves away from the outer peripheral surface 2 b of the guide ring 2. Tensioning prevents thread entanglement. That is, at the two left and right locations where the left and right support legs 31 of the guide frame 3 are separated from the outer peripheral surface 2b of the guide ring 2, a steep valley is formed between the support leg 31 and the outer peripheral surface 2b of the guide ring 2. A shaped space is formed in a V shape. The bridge parts 4 make up for the two left and right spaces. Specifically, the bridge part 4 includes a pair of left and right compensation portions 40 located in a space between the guide frame 3 and the guide ring 2 at two left and right positions where the guide frame 3 is separated from the outer peripheral surface 2 b of the guide ring 2. And the connection part 41 which connects both the compensation parts 40 is provided.

  The bridge part 4 is composed of a single member. Therefore, the pair of left and right supplementary portions 40 and the connecting portion 41 between them are integrally formed. 1 is a separation point where the guide frame 3 is separated from the guide ring 2 in a front view as shown in FIG. 1 so as to be able to be inserted into the space corresponding to the space between the guide ring 2 and the guide frame 3. In other words, the taper shape becomes gradually narrower toward P. In other words, the taper shape becomes wider as it moves away from the separation point P. Further, the connecting portion 41 extends so as to draw an arc along the outer peripheral surface 2 b of the guide ring 2. In addition, it is preferable that the dimension (thickness) of the guide ring 2 in the connecting portion 41 in the radial direction is smaller than the size in the direction of the center line 50 of the guide ring 2 in the connecting portion 41, and the bridge part 4 can be reduced in weight.

  The bridge part 4 includes an upper surface 42 positioned on the guide ring 2 side, a lower surface positioned on the anti-guide ring 2 side, and a pair of left and right side surfaces 44. When viewed in the inner and outer directions with respect to the center of the guide ring 2, the upper surface 42 of the bridge part 4 is an inner surface because it is an inner surface, and the lower surface of the bridge part 4 is an outer surface because it is an outer surface. is there. The upper surface 42 of the bridge part 4 abuts on the outer peripheral surface 2 b of the guide ring 2. Accordingly, the upper surface 42 of the bridge part 4 has a shape along the outer peripheral surface 2b of the guide ring 2, and a central angle corresponding to the angular range so that it can contact the predetermined angular range of the outer peripheral surface 2b of the guide ring 2. It has a concave shape with an arc shape when viewed from the front. In addition, it is preferable that the angle range in which the upper surface 42 of the bridge part 4 contacts the outer peripheral surface 2b of the guide ring 2 is less than 180 degrees.

  Further, the upper surface 42 of the bridge part 4 has an outer peripheral surface 2b of the guide ring 2 so that a sufficient contact area with the outer peripheral surface 2b of the guide ring 2 can be secured in a sectional view cut along the radial direction of the guide ring 2. It is preferable that the cross-sectional shape corresponds to. As described above, the circumferential groove 20 is formed on the outer peripheral surface 2 b of the guide ring 2. Therefore, the upper surface 42 of the bridge part 4 preferably has a cross-sectional shape that engages with the circumferential groove 20 of the outer peripheral surface 2b of the guide ring 2 in a cross-sectional view cut along the radial direction of the guide ring 2. A convex curved surface that is convexly convex toward the center of 2 is preferable.

  The lower surface of the bridge part 4 is a surface located on the opposite side to the upper surface 42. The lower surface of the bridge part 4 corresponds to the outer peripheral surface 2b of the guide ring 2, and an arcuate portion 43a that is concentric with the upper surface 42 of the bridge part 4 and the guide ring 2, and left and right sides of the arcuate portion 23a, respectively. A pair of left and right curved surface portions 43b that are formed and curved in a concave shape so as to gradually move away from the guide ring 2 as the guide frame 3 is approached. In other words, the curved surface portion 43b on the lower surface of the bridge part 4 is curved so as to gradually move away from the upper surface 42 of the bridge part 4 as it approaches the left and right ends of the bridge part 4.

  The side surface 44 of the bridge part 4 abuts on the inside of the support leg 31 of the guide frame 3. The side surface 44 of the bridge part 4 is preferably formed with an engagement groove (not shown) in which the guide frame 3 can be engaged. The engagement groove has an arcuate cross-sectional shape corresponding to a circular shape that is a cross-sectional shape of the hollow metal wire 34 in a cross-sectional view. The bridge part 4 abuts on the tip region 31 a which is a region located on the same plane as the frame portion 30 in the support leg portion 31 of the guide frame 3, but does not abut on the intermediate region 31 b of the support leg portion 31. Therefore, the bridge part 4 can be a plate having a constant thickness in the front-rear direction (the direction of the center line 50 of the guide ring 2), and the thickness is preferably a hollow metal of the guide frame 3. It is equal to the outer diameter of the wire 34.

  The material of the bridge part 4 is preferably a material having a small specific gravity, for example, a hard resin or a fiber reinforced resin, and particularly preferably a fiber reinforced resin using carbon fiber as a reinforced fiber. A formed resin molded product is preferable. Note that, like the guide frame 3, it may be made of a metal such as a titanium alloy.

  The fishing line guide 1 configured as described above is assembled and manufactured in the following order, for example. As described above, the guide ring 2 is manufactured from the metal plate 21 such as a titanium alloy as shown in FIGS. Then, as shown in FIG. 10, the bridge part 4 manufactured separately is combined with the guide ring 2. Note that FIG. 10 shows the guide ring 2 and the bridge part 4 as seen from the rear side as in FIG. FIG. 10 (a) shows the state before the union, FIG. 10 (b) shows the state after the union, and FIG. 10 (c) shows only the guide ring 2 in a partial cross section in the state after the union. It is a thing. The bridge part 4 and the guide ring 2 are bonded and fixed by bringing the upper surface 42 of the bridge part 4 into contact with the circumferential groove 20 of the outer peripheral surface 2 b of the guide ring 2.

  On the other hand, as described above, the guide frame 3 is formed from a single hollow metal wire. The guide ring 2 in which the bridge parts 4 are combined is mounted on the guide frame 3. The bridge part 4 and the guide ring 2 may be attached to the guide frame 3 separately and independently. When the guide ring 2 is attached to the guide frame 3, the guide ring 2 is pushed in from the rear side of the guide frame 3 toward the front side as shown in FIG.

  The diameter G4 of the flange 23 on the front side of the guide ring 2 is the outer diameter of the front end of the guide ring 2, and the diameter G3 of the flange 22 on the rear side of the guide ring 2 is the outer diameter of the rear end of the guide ring 2. is there. The diameter G4 of the front flange portion 23 of the guide ring 2 is smaller than the diameter G3 of the rear flange portion 22, but larger than the inner diameter D of the frame portion 30 of the guide frame 3. Therefore, when the guide ring 2 is pressed toward the guide frame 3 in the direction of the center line 50, the frame portion 30 and the left and right support leg portions 31 of the guide frame 3 are elastically deformed so as to expand left and right. 2 is pushed into the frame portion 30 of the guide frame 3, and the frame portion 30 of the guide frame 3 is engaged with the circumferential groove 20 of the guide ring 2. The frame portion 30 of the guide frame 3 has a C-shape that opens downward, and the support leg portion 31 also has a two-leg configuration separated from the left and right, so that the guide frame 3 engages with the circumferential groove 20 of the guide ring 2. Even if it is a structure, when the guide ring 2 is pushed in, the guide frame 3 is elastically deformed so that the diameter of the guide frame 3 is expanded while opening left and right, and the guide ring 2 is received. Further, since the metal wire constituting the guide frame 3 has a circular cross section, the guide ring 2 can be smoothly pushed into the frame portion 30 of the guide frame 3.

  When the guide ring 2 is pushed into the frame portion 30 of the guide frame 3, the guide frame 3 is reduced in diameter so as to return to its original state by its own elastic restoring force, and as shown in FIG. The frame portion 30 automatically engages with the circumferential groove 20 of the guide ring 2 to hold the guide ring 2. Moreover, since it is a hollow metal wire, it is easy to elastically deform compared with the solid metal wire of the same diameter, and the guide ring 2 can be inserted easily and smoothly. Similarly, the bridge part 4 can be easily mounted by elastically deforming so that the guide frame 3 opens to the left and right, and the support legs 31 of the guide frame 3 are fitted into the engaging grooves on both side surfaces 44 of the bridge part 4. The leading area 31a is engaged. An adhesive may be used when the guide ring 2 or the bridge part 4 is attached to the guide frame 3. The adhesive may be used supplementarily, or may be configured to be bonded and fixed only with the adhesive without providing the circumferential groove 20 or the engagement groove, for example.

  The fishing line guide 1 manufactured in this way is attached to the outer peripheral surface of the fishing rod housing 5 as shown in FIG. Specifically, the attachment portion 32 of the fishing line guide 1 is placed on the rod body 5, and the winding line 6 is wound around the attachment portion 32 and the rod body 5 to bind the fishing line guide 1 to the rod body 5. . More specifically, the fishing line guide 1 is fixed to the housing 5 by winding the spool 6 from the housing 5 to the flat portion 32 c of the attachment portion 32. Further, an adhesive synthetic resin (adhesive) is applied to the wound portion of the wound yarn 6 and hardened. In the present embodiment, the guide ring 2 is in an upright posture in the attached state to the housing 5, that is, the center line 50 of the guide ring 2 is parallel to the center line 51 of the housing 5, but is inclined forward. It may be a forward leaning posture.

  Since the flat part 32c is formed in the rear part of the attachment part 32, the fishing line guide 1 in this embodiment is compared with the case where the attachment part 32 is the shape of the hollow metal wire which is not crushed. The adhesion to the housing 5 is increased, and the wound yarn 6 can be tightly wound around the flat portion 32c. Therefore, the fishing line guide 1 can be firmly attached to the housing 5. In particular, since the concave surface portion 38 is formed on the lower surface of the flat portion 32c, it becomes easier to follow along the housing 5 than in the case where the lower surface of the flat portion 32c is flat, and the adhesion is further increased. 32, since the concave surface portion 38 is continuous in the left-right direction so as to straddle the left and right metal wires, good adhesion to the housing 5 even when the predetermined length regions at both ends of the metal wire are arranged side by side Sex is secured. In addition, since both sides of the flat portion 32c are cut obliquely toward the rear side and are formed narrower toward the rear side, the flat portion 32c can be more firmly attached to the casing 5 and the wound yarn 6 can be attached to the flat portion 32c. It can be wrapped neatly and has a good appearance.

  And in the fishing line guide 1 attached to the rod body 5 in this way, since the guide frame 3 is made of a hollow metal wire, it is formed by punching a metal plate into a predetermined shape as in the prior art. The weight can be easily reduced as compared with the configuration. In addition, the conventional guide frame 3 punched out of the metal plate has a cross-sectional shape with an edge, so that the resistance when the fishing line comes into contact with the guide frame 3 is large, so that the yarn is likely to be entangled. The cast feel is not good. On the other hand, since the guide frame 3 of the fishing line guide 1 of the present embodiment is made of a metal wire having a circular cross section and has a circular cross section without an edge, the fishing line contacts the guide frame 3. The fishing line has good slipperiness and smoothness, hardly causes entanglement, and has an excellent cast feel.

  Further, since the pair of left and right support legs 31 of the guide frame 3 are curved so as to bulge outward in the left-right direction, coupled with the fact that the guide frame 3 has a circular cross-sectional shape without an edge, the fishing line guide 1 The fishing line is difficult to get tangled. Further, since the central angle θ of the frame portion 30 is smaller than the central angle α between the contact points 54, the support leg portion 31 can be formed to smoothly swell from the circumferential end portion of the frame portion 30. The constricted portion that is constricted radially inward is not generated at the boundary portion between the portion 30 and the support leg portion 31, and the shape is smoothly continuous from the frame portion 30 to the support leg portion 31. Is prevented.

  Further, even if the root region 31c of the support leg 31 is curved in the front-rear direction, the hollow metal wire is maintained in the cross-sectional shape without being crushed in the root region 31c. Even in 31c, the cross-sectional shape has no edge, and a good cast feeling with little yarn contact is obtained, and yarn entanglement is further prevented. Further, since the metal wire is not crushed in the root region 31c of the support leg 31, the strength is improved as compared with the crushed form.

  Further, since the bridge part 4 connects the pair of left and right support legs 31, the guide frame 3 is reinforced, and the strength of the guide frame 3 is improved. The bridge part 4 compensates for the space between the guide frame 3 and the outer peripheral surface 2b of the guide ring 2 in the vicinity of the two left and right separation points P where the guide frame 3 moves away from the outer peripheral surface 2b of the guide ring 2. Therefore, the bridge parts 4 can prevent the yarn entanglement that is likely to occur in the vicinity of the two separation points P. In particular, since the concave curved surface portion 43b is formed on the lower surface of the filling portion 40 of the bridge part 4, the tangled yarn can be further suppressed by the curved surface portion 43b.

  Furthermore, since the non-circular portion of the entire circumference of the guide ring 2 where the frame portion 30 of the guide frame 3 does not circulate is held by the bridge part 4, the guide ring 2 is not only the frame portion 30 of the guide frame 3 but also the bridge. As a result, the holding force of the guide ring 2 is improved. Moreover, since the bridge part 4 is also engaged with the circumferential groove 20 of the guide ring 2, and the support legs 31 of the guide frame 3 are also engaged with both side surfaces 44 of the bridge part 4, the guide ring 2, the guide The frame 3 and the bridge part 4 are firmly integrated, and the strength of the fishing line guide 1 is further improved. Further, by engaging the bridge part 4 with the circumferential groove 20 of the guide ring 2, the vertical dimension of the bridge part 4 can be reduced and the weight can be reduced. In addition, since the bridge part 4 connects the support legs 31 to each other within the range of the tip region 31 a that is not curved in the front-rear direction, the bridge part 4 is positioned on the same plane as the frame part 30 of the guide frame 3. It is possible to suppress the size of the bridge part 4 in the front-rear direction. By providing the bridge part 4 in this way, it is possible to suppress an excessive increase in weight while increasing the strength of the fishing line guide 1 and preventing entanglement.

  In the present embodiment, the support leg 31 has a two-leg configuration, but may have a one-leg configuration. Further, the attachment portion 32 may also have a single leg configuration.
