Description

  The present invention relates to a fishing line guide for guiding a fishing line, a fishing rod provided with the same, and a guide frame of the fishing line guide.

  A fishing line guide for guiding a fishing line comprises, for example, a guide frame formed by punching a metal plate as described in the following Patent Document 1, and a guide ring attached to a hole of the guide frame to guide the fishing line. Is generally used. However, since the guide frame is formed by punching a metal plate, there is a limit in achieving weight reduction while securing strength.

  Therefore, the present inventors examined forming the guide frame from a thin metal wire. That is, a metal wire rod is bent in a U shape along the outer peripheral surface of the guide ring, and a frame portion in contact with a predetermined angle area of the entire outer peripheral surface of the guide ring, and a mounting portion for mounting on a housing A pair of left and right support legs connecting the both ends in the circumferential direction of the frame and the front end of the mounting portion in a straight line are integrally formed of a metal wire. However, there has been a demand for an improvement measure that can further suppress the occurrence of yarn tangling in the fishing line guide.

JP 2001-238577 A

  Therefore, it is an object of the present invention to reduce the weight of the fishing line guide and to suppress the occurrence of yarn entanglement.

The present invention has been made to solve the above problems, and a fishing line guide according to the present invention comprises a guide ring for guiding a fishing line, and a fishing line guide comprising a guide frame for holding the guide ring. The guide frame is formed of a hollow metal wire rod having a circular cross section, and the guide frame is a frame portion that abuts a predetermined angle area of the entire outer periphery of the guide ring, and an attachment portion for attaching to the housing When, and a circumferential direction of the both end portions and a mounting portion and a pair of right and left support legs for connecting the frame portion, a pair of right and left support legs, Ri shape der curved to Rise useless outside of the left and right directions, The root region of the support leg portion has a curved shape curved in the front-rear direction, and the metal wire in the root region maintains its cross-sectional shape without being crushed .

  In the fishing line guide of this configuration, the guide frame is made of a metal wire, so that the weight can be reduced easily compared to a guide frame formed by punching a metal plate into a predetermined shape. In addition, in the guide frame formed by punching out a conventional metal plate, the cross-sectional shape has an edge, so the resistance when the fishing line comes in contact with the guide frame is large, and thus yarn entanglement tends to occur, and , Cast feel too bad. On the other hand, when the guide frame is formed of a metal wire rod having a circular cross section, since it has a cross-sectional shape without edges, the slipperiness of the fishing line when the fishing line contacts the guide frame is good and smooth Tangle is hard to occur, and the cast feel is also excellent. Moreover, since the left and right support leg portions of the guide frame do not extend linearly from both end portions in the circumferential direction of the frame portion to the attachment portion, they are curved so as to expand outward in the left and right direction, Combined with the edgeless cross-sectional shape, the fishing line is less likely to be entangled in the guide frame.

  In particular, when the center angle of the frame portion is tangent to the end portion on the root side of both support legs toward the virtual circle in which the frame portion extends in the circumferential direction, the contact point between the tangent line and the virtual circle Is preferably smaller than the central angle of the tip side away from the mounting portion. The end portion on the root side of the support leg portion is the end portion on the attachment portion side, and is a boundary portion between the support leg portion and the attachment portion. The guide ring is circular in a front view as viewed in the center line direction, and the virtual circle extends 360 degrees in the circumferential direction of the inner peripheral surface of the frame portion which is an abutment surface that abuts on the guide ring It is a circle when the inner peripheral surface of is seen in the direction of the center line of the guide ring. The tangent to the imaginary circle is a tangent drawn from the inner surface in the left-right direction of the end on the root side of the support leg toward the imaginary circle when the fishing line guide is viewed in the direction of the center line of the guide ring . When the central angle of the frame is smaller than the central angle between the two contacts, the support leg is directed outward in the left-right direction and smooth from the circumferential end of the frame. The frame portion and the support leg portion are in a smoothly continuous state. That is, a narrow portion which is narrowed toward the inside in the left and right direction does not occur at the boundary between the frame and the support leg, and a smooth continuous shape is formed from the frame to the support leg, further entanglement Is prevented.

When the guide frame is formed of a hollow metal wire, if the radius of curvature of the root region of the support leg is small, the hollow metal wire is crushed in the root region. Therefore, if the root region of the support leg is curved with a large radius of curvature to the extent that the hollow metal wire is not crushed, the cross-sectional shape also becomes edgeless in the root region of the support leg and yarn entanglement is more It is further prevented.

  Furthermore, the support leg portion is composed of a tip region near the frame portion, a root region near the attachment portion, and an intermediate region which is a portion between the tip region and the root region, and the tip of the support leg portion The region is on the same plane as the frame without curving in the longitudinal direction, and the middle region and the root region of the support leg are curved in the longitudinal direction, and the left and right support legs are connected to the left and right Preferably, a bridge part is provided, which connects the support legs within the area of the tip. If the tip region of the support leg portion is not curved in the front-rear direction but on the same plane as the frame portion, the frame portion and the support leg portion will be smoothly continuous, and yarn entanglement can be prevented. Further, by providing the bridge parts, the pair of left and right support legs are connected to reinforce the guide frame, and the strength of the guide frame is improved. Further, since the bridge part is in contact with and connected to the support leg within the range of the tip area, the bridge part can be positioned on the same plane as the frame, and the thickness can be reduced. Therefore, it is possible to suppress an excessive weight increase while increasing the strength by the bridge parts.

Further, the fishing line guide according to the present invention comprises a guide ring for guiding a fishing line, a guide frame for holding the guide ring, and a cylindrical body fixedly mounted on the outer peripheral surface of the rod so as to move freely. A guide frame comprising a hollow metal wire rod having a circular cross section , and the guide frame comprises a frame portion which abuts a predetermined angle area of the entire outer periphery of the guide ring, and a tubular body And a pair of left and right support legs connecting the two circumferential ends of the frame and the mounting portion, and the left and right support legs are curved so as to expand outward in the left and right direction, respectively. Ri shape der, root area of the support legs is a curved shape curved in the longitudinal direction, characterized in that it maintains its cross-sectional shape without collapsing pushing the metal wire in該根source area.

  Further, the fishing rod according to the present invention is provided 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, and is made of a hollow metal wire rod having a circular cross section, and in a predetermined angle region of the entire outer periphery of the guide ring. It has a frame portion to be in contact with, a mounting portion for mounting to a housing, and a pair of left and right support legs connecting the two end portions in the circumferential direction of the frame and the mounting portion. shape der curved to Rise useless outside of the left-right direction is, the root region of the support legs is a curved shape curved in the longitudinal direction, it maintains its cross-sectional shape without collapsing pushing the metal wire in該根source area It is characterized by

As described above, the guide frame is formed of a hollow metal wire rod having a circular cross section, and the support leg continuous from the circumferential end of the frame has a curved shape so as to expand outward. Therefore, weight reduction and yarn entanglement can be suppressed as compared with a guide frame formed by punching from a conventional metal plate.

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

  In the figure, the axial direction of the housing 5 is referred to as the front-rear direction, the tip side (front side) is indicated by a symbol X1, and the buttocks side (rear side) is indicated by a symbol X2. A direction perpendicular to the axial direction of the housing 5 and on a plane passing through the center line 50 of the guide ring 2 is a vertical direction, and a direction away from the housing 5 is indicated by a symbol Z 1. Is indicated by a symbol Z2 with the direction approaching the lower side. The upper side may be referred to as the distal side, and the lower side as the proximal side. Further, in a plan view viewed from the upper side, a direction orthogonal to the axial direction of the casing 5 is referred to as a left and right direction, which is indicated by a symbol Y. The axial direction (longitudinal direction) of the casing 5 is the direction of the center line 51 of the casing 5 and is the longitudinal direction of the mounting portion 32 of the guide frame 3 described later, and the lateral direction is the short side of the mounting portion 32 It is a direction (width direction).

<Guide ring 2>
The guide ring 2 has, for example, a circular annular shape as shown in FIG. 1, but may have an oval shape, an oval shape or the like. 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 excellent in wear resistance. For example, a ceramic typified by SiC (silicon carbide) may be used as a matter of course, but it is made of titanium in this embodiment. As titanium, a titanium alloy is preferable. A titanium alloy is a mixture of an α phase and a β phase, and is a near α type (an α alloy to which a small amount of a β stabilizing element is added) which is mainly an α phase and a β phase remains in part. The 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 alpha 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, and is, for example, Ti-3Al-2.5V or Ti-6Al-4V. The β-type is also referred to as metastable β-type, and has more β-stabilizing elements and less α-stabilizing elements than the α + β-type. In the β form, the α phase is dispersed and formed as fine particles in the residual β phase, and therefore, even in the β form, the α phase and the β phase are present in the form of a mottled pattern . Examples of the β type include Ti-15V-3Cr-3Sn-3Al, Ti-3Al-8V-6Cr-4Zr-4Mo, Ti-10V-2Fe-3Al, etc., and in particular, the cold workability 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 the fishing line directly guides the fishing line as the fishing line slides on the inner peripheral surface 2 a of the guide ring 2. As shown in FIGS. 9B and 11, the inner peripheral surface 2 a of the guide ring 2 is a curved surface curved in the front-rear direction so as to be an inner convex (central side convex) in a cross sectional view. The outer peripheral surface 2b of the guide ring 2 is also a curved surface which is curved in the front-rear direction so as to be inward convex (convex on the center side) in a cross sectional view. That is, in a cross-sectional view cut in the direction of the center line 50, the guide ring 2 is curved in an arc so as to be convex on the center side and a convex inner circumferential surface 2a curved in an arc. 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. Further, 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 is provided with annular ridges 22 and 23 protruding radially outward at both ends in the direction of the center line 50, that is, both front and rear ends. A recessed circumferential groove 20 is formed on the outer peripheral surface 2b of the guide ring 2 over the entire circumference between the flanges 22 and 23 by forming the ridges 22 and 23 at both front and rear ends. become. And it becomes the cross-sectional shape of the outer peripheral surface 2b smoothly continued from the ridges 22 and 23 to the circumferential groove 20, and the outer peripheral surface 2b of the guide ring 2 is curved in a central 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 flanges 22 and 23 are both larger than the inner diameter D of the frame 30 of the guide frame 3 described later (the diameter at the vertex which is the smallest diameter portion of the inner peripheral surface of the frame 30) . The diameters G3 and G4 of the front and rear ridges 22 and 23 may be identical to each other, but it is preferable that one diameter G4 be smaller than the other diameter G3. In the present embodiment, the diameter of the front ridge 23 G4 is smaller than the diameter G3 of the rear ridge 22. 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 described later, the frame 30 of the guide frame 3 and the bridge part 4 engage 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 rod having a circular cross section, and it is preferable that an angular range of 90 degrees or more and less than 180 degrees of the entire circumference of the circular cross section be 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 (inward and outward directions), that is, the outer diameter of the guide ring 2 (diameter G3 of the larger rear flange 22) Although the 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 titanium alloy is punched into a donut shape, and as shown in FIG. 9 (a), the punched donut-shaped metal plate 21 is shown by an arrow from one of the front and back surfaces. The one end portion of the cylindrical metal plate 21 is curved outward in the radial direction to form a flange 22 while being pressed into a cylindrical shape and deformed into a cylindrical shape. Next, as shown by the arrow from the other side which is the opposite side as shown in FIG. 9 (b), the cylindrical metal plate 21 is further pressed and the other end is also radially outward like the one end. The ridge portion 23 is formed by curving in a bowl shape, and the guide ring 2 is formed as an arc-shaped cross-sectional shape in which the cross-sectional shape of the cylindrical metal plate 21 is curved on the center side as a whole.

  The size of the curvature of the other end of the metal plate 21 is smaller than that of the one end, that is, the size of the curvature of the other end of the guide ring 2 is smaller than that of the one end. Accordingly, 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 manner has an annular collar 22 and 23 projecting radially outward at both ends thereof, and the guide frame 3 is formed between the collar 22 and 23. Is engaged. Specifically, as shown in FIG. 2 and FIG. 3, one end with a relatively large degree of radial outward curvature is the rear side (rear end), and the degree of radial outward curvature is relatively small. The guide frame 3 is mounted such that the other end is on the front side (front end). The guide ring 2 is formed with flanges 22 and 23 at both ends thereof, and between them is a circumferential groove 20, and the guide frame 3 is engaged with the circumferential groove 20. The movement is restricted by the circumferential groove 20 or both the front and rear ridges 22 and 23, and it is also prevented from coming off to the front side or the rear side. In particular, since the outer peripheral surface 2b of the guide ring 2 including the flanges 22 and 23 is formed in an arc shape having a convex convex on the center side, the engagement with the frame 30 of the guide frame 3 made of a metal wire rod having a circular cross section The combined state is stable, and the back and forth movement of the guide ring 2 can be reliably restricted.

  The outer peripheral surface 2b of the guide ring 2 and the frame portion 30 of the guide frame 3 may be in surface contact in a cross-sectional view cut in the radial direction, but may be in point contact. The guide frame 3 is a metal wire rod having a circular cross section, but when the outer peripheral surface 2 b of the guide ring 2 and the guide frame 3 are in point contact, they are spaced not in one point but in front and back (circumferential direction of circular cross section of metal wire rod) It is preferable to make contact at a plurality of points, and it is more preferable to make contact at two or three points.

<Guide frame 3>
The guide frame 3 is provided with a mounting portion 32 for mounting on the outer peripheral surface of the housing 5, and rises upward from the mounting portion 32, that is, away from the housing 5 radially outward. And a frame main body for holding the guide ring 2 at a remote position. The frame body includes a frame 30 for holding the guide ring 2, and a support leg 31 for connecting the frame 30 and the mounting portion 32. That is, the frame main body portion includes the frame portion 30 on the distal end side (upper side) and the support leg portion 31 on the proximal end side (lower side).

  The guide frame 3 is made 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 an aluminum alloy. Among them, titanium alloy is preferable from the viewpoint of weight reduction. The details of the titanium alloy are the same as those of the guide ring 2, and because they have good cold workability and can easily ensure the strength of the members, β-type titanium alloys are preferable. The metal wire has a circular cross-sectional shape. The metal wire is solid or hollow, and in particular, it is easy to secure a contact area with the guide ring 2 in terms of achieving both weight reduction and strength, so that the metal wire is a wire, that is, a wire. Shaped pipe material is preferred. 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 of the present embodiment is made of a hollow metal wire.

  As described above, the guide frame 3 is formed by bending a single wire, but its shape is U-shaped in a rear view as shown in FIGS. 2 and 4 or in a front view as viewed from the front side. The two end portions of the metal wire are aligned in one direction. Since the guide frame 3 is configured by bending one metal wire rod as a whole into a U shape as described above, the support leg portion 31 and the mounting portion 32 both have two metal wires arranged side by side in the left and right direction. It has the composition of The left and right legs are symmetrical in shape.

  Further, as shown in FIGS. 3 and 5, the frame main body portion extends upward in a straight line after bending upward from the front end portion of the mounting portion 32. Portions of the frame main body portion which are curved and directed upward are a root region 31 c and an intermediate region 31 b of the support leg 31 described later. In the present embodiment, the frame main body finally rises at a right angle with respect to the mounting portion 32, and accordingly, 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 stand up so that the center line 50 of the guide ring 2 is not parallel to the center line 51 of the housing 5 but inclined. That is, the frame main body may be configured to rise in a forwardly inclined posture.

<Frame portion 30>
The frame portion 30 is a portion for holding the guide ring 2 inside thereof, and constitutes a region on the tip side of the frame main body portion, and is formed in an arc shape having a predetermined central angle θ. The frame portion 30 is formed in a C-shape opened downward by bending a metal wire along the outer peripheral surface of the guide ring 2. The frame portion 30 has a size and a 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 the present embodiment, since the circular guide ring 2 is used, the frame portion 30 also has an arc shape correspondingly, but the elliptical guide ring 2 When used, the frame portion 30 also has an elliptical arc shape correspondingly. The frame portion 30 orbits only the upper predetermined range of the entire circumference of the guide ring 2 to support the outer peripheral surface 2 b of the guide ring 2.

  Although the frame portion 30 goes around 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 near 180 degrees, and is 150 degrees to 240 degrees. In particular, it is more preferably 160 degrees to 200 degrees. In the present embodiment, the central angle θ of the frame 30 is an angle slightly beyond the half circumference of the guide ring 2. In FIG. 4, a virtual circle 52 obtained by extending the inner circumferential surface of the frame portion 30 is indicated by a two-dot chain line. The virtual circle 52 is a circle when the inner circumferential surface of the frame portion 30 is extended to 360 degrees in the circumferential direction, and the inner circumferential surface of 360 degrees is viewed in the direction of the center line 50 of the guide ring 2. The diameter D of the imaginary circle 52 is the inner diameter D of the frame 30 (the diameter at the top of the inner peripheral surface of the frame 30 which is the smallest diameter portion). Further, in FIG. 4, a tangent line 53 which is in contact with the virtual circle 52 with the lower end (end on the root side) of the support leg 31 as a starting point is indicated by a two-dot chain line. The tangent 53 is a tangent drawn from the inner surface in the left-right direction of the lower end portion of the support leg 31 toward the virtual circle 52 when the fishing line guide 1 is viewed in the direction of the center line 50 of the guide ring 2 . It is preferable that the central angle θ of the frame portion 30 be smaller than the central angle α of the tip side which is the central angle between the contact points 54 where the two tangent lines 53 contact the virtual circle 52 and which is the side away from the mounting 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. The support leg portion 31 has a configuration of two legs arranged side by side as shown in FIG. First, the shape of the support leg 31 in a front view as viewed from the front or in a rear view as viewed from the rear will be described. The pair of left and right support legs 31 are symmetrical to each other. The pair of left and right support legs 31 respectively extend downward from both end portions of the frame 30 in the circumferential direction, and are V-shaped in a front view or a rear view as a whole. More specifically, the pair of left and right support legs 31 are curved so as to expand outward in the left-right direction. The pair of left and right support legs 31 extend downward from the both ends of the frame 30 so as to expand outward in the left-right direction, and then approach each other, that is, narrow the distance therebetween. It extends inwardly and at its lower end is in abutment with one another. However, the lower ends of the pair of left and right support legs 31 may be in a state of being close to each other via a slight gap. The center angle θ of the frame 30 is equal to the center angle α between the contact points 54 where the tangent line 53 contacts the virtual circle 52 and is the side away from the mounting part 32, and along the tangent line 53 The support leg 31 can be formed in a straight line, but the central angle θ of the frame 30 is the central angle between the contacts 54 where the tangent 53 is in contact with the virtual circle 52 and is away from the attachment 32 If the shape of the support leg 31 in a front view or a back view is a curved shape that is expanded outward with respect to the tangent line 53 while making it smaller than a certain central angle α on the front side, yarn tangling prevention is effective.

  The pair of left and right support leg portions 31 are curved in such a manner as to expand outward in the left and right direction, but in the present embodiment, since the central angle θ of the frame portion 30 is 180 degrees or more, both support leg portions The maximum separation distance between 31 is equal to the inner diameter D of the frame 30. That is, the diameter D of the imaginary circle 52 in FIG. 4 and the maximum separation distance between the support legs 31 are equal. Further, in the present embodiment, since the pair of left and right support legs 31 abuts at the lower end, the separation distance between the lower ends of the pair of left and right support legs 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 are curved in the lateral direction, respectively, and the maximum separation distance between the support leg portions 31 is The inner diameter D of the frame 30 may be larger.

  Next, the shape of the support leg 31 in a side view when viewed from the left and right as shown in FIGS. 3 and 5 will be described. The support legs 31 can be divided into three regions. That is, the support leg portion 31 is composed of a front area 31a near the frame 30, a root area 31c near the attachment section 32, and an intermediate area 31b which is a portion between the front area 31a and the root area 31c. There is. The tip area 31 a of the support leg 31 extends downward from the circumferential end of the frame 30 without bending in the front-rear direction, and is on the same plane as the frame 30. That is, the tip area 31 a of the support leg 31 is located on a plane orthogonal to the center line of the frame 30 (the center line 50 of the guide ring 2). The intermediate region 31 b and the root region 31 c of the support leg 31 each have a curved shape curved in the front-rear direction. Therefore, the middle region 31 b and the root 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 middle region 31 b of the support leg 31 extends downward from the lower end portion of the tip region 31 a of the support leg 31 while curving rearward. The degree of curvature in the front-rear direction in the middle region 31 b of the support leg 31 is gentler than the degree of curvature in the front-rear direction in the root region 31 c of the support leg 31. The root area 31 c of the support leg 31 extends downward while curving rearward from the lower end of the middle area 31 b of the support leg 31 to the front end of the mounting portion 32. The degree of curvature of the root region 31c of the support leg 31 in the front-rear direction is more precise than that of the intermediate region 31b of the support leg 31. The radius of curvature is relatively small, but the metal wire is crushed in the root region 31c. Without maintaining its cross-sectional shape. That is, the degree of curvature in the front-rear direction in the root region 31c of the support leg 31 is such that the metal wire does not collapse in the radial direction due to the curvature in the front-rear direction, and the curvature radius of the curvature in the front-rear direction is the metal wire The radius of curvature is so small that it does not collapse in the radial direction. Thus, the metal wire in the support leg 31 maintains the circular cross section over the entire area including the root area 31 c.

<Mounting part 32>
The mounting portion 32 extends from the lower end portion of the support leg 31 toward the rear side (the buttock side) in a straight line in plan view. The attachment portion 32 has a two-leg configuration including a predetermined length area of both end portions of one metal wire rod. That is, the attachment portion 32 is configured such that a pair of left and right linear bodies consisting of a predetermined length area at both ends of one metal wire rod are arranged in parallel in the left and right without spacing, and each linear body is a support leg It extends rearward from the lower end of the portion 31. The pair of left and right linear bodies are joined and integrated with each other. The bonding method is optional, but preferably by welding.

  The mounting portion 32 is not uniform in thickness over the entire length, and is composed of three regions having different thicknesses. That is, the attachment portion 32 is located between the straight portion 32a having a circular cross section located on the front side, the flat portion 32c having a plate shape located on the rear side, and the straight portion 32a and the flat portion 32c, and is directed to the rear side. And the tapered portion 32b whose thickness (dimension in the vertical direction) is gradually reduced. The straight portion 32 a constitutes the front of the mounting portion 32 and extends rearward from the root region 31 c of the support leg 31. The straight portion 32a is a portion where the hollow metal wire maintains its circular cross-sectional shape. The straight portion 32 a is not curved in the front-rear direction, but extends linearly along the front-rear direction. The tapered 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 downward inclination of the upper surface reduces the thickness thereof toward the rear side. ing. In the tapered portion 32b, the hollow metal wire is compressed in the vertical direction, and the amount of compression is gradually increased rearward, and is connected to the flat portion 32c at the rear end. The flat portion 32 c constitutes a 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.

  The width (dimension in the left-right direction) of the mounting portion 32 may be constant, but as shown in FIG. 6, it is preferable to gradually narrow the width of the rear portion toward the rear side. Specifically, the straight portion 32a and the tapered portion 32b have a constant width, and the flat portion 32c is formed to be gradually narrower toward the rear side. The left and right side portions of the flat portion 32c are cut away at predetermined portions so that the width of the flat portion 32c gradually narrows toward the rear side. The shape before being cut off is shown by a two-dot chain line in FIG.

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

  The mounting portion 32 is wound around the outer peripheral surface of the casing 5 by the winding thread 6 as shown in FIG. 2, but on the left and right side portions of the mounting portion 32 to prevent the mounting portion 32 from coming off the casing 5 A notch (not shown) may be provided. As described above, when the notches are provided on the left and right sides of the attachment portion 32, the winding yarn 6 is wound more firmly at the notches.

  In the guide frame 3, first, one metal wire rod is bent into a U-shape and curved in the front-rear direction, and both end predetermined length regions of the metal wire rod are aligned side by side. Next, the predetermined length regions of both end portions of the metal wire rods arranged side by side are welded and integrally joined to each other to form the mounting portion 32. Next, the metal wire at the rear of the mounting 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 off obliquely. Alternatively, after the flat portion 32c is formed, the left and right side portions of the flat portion 32c may be cut in a separate process. Then, the formed flat portion 32c is further pressed vertically to bend and deform the flat portion 32c in the left-right direction, thereby forming the concave portion 38 on the lower surface of the flat portion 32c. By forming the flat portion 32c after joining the predetermined regions of both end portions of the metal wire in this manner, the flat portion 32c integrated with the lower surface of the left and right metal wire can be formed. Further, by bending and deforming the flat portion 32c thereafter, the concave portion 38 continuous in the left-right direction can be formed so as to straddle the left and right metal wire rods.

<Bridge part 4>
As described above, the frame portion 30 has a C-shape opened downward, and the support leg portion 31 has a configuration of a pair of right and left two legs, and is separated left and right. Further, the frame portion 30 contacts 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 supplement the holding of the guide ring 2 by the guide frame 3, a bridge part 4 is provided at a lower position of the guide ring 2.

  The bridge part 4 is located inside the guide frame 3 and is located on the side of the mounting portion 32 with respect to the guide ring 2 (the side closer to the housing 5 in the mounting state to the housing 5). The bridge part 4 is in contact with the lower predetermined angle area of the outer peripheral surface 2b of the guide ring 2 to hold the lower predetermined angle area 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. More specifically, the bridge parts 4 connect the support legs 31 with each other within the range of the tip area 31 a of the entire area of the support legs 31. That is, it is preferable that the bridge parts 4 connect not the middle area 31 b of the support leg 31 but the tip area 31 a. The guide frame 3 is reinforced by the bridge part 4 connecting the pair of left and right support legs 31 to each other to function as a tension part, and the vicinity of the opening of the frame 30 of the guide frame 3 is connected by the bridge part 4 It will also be In addition, the bridge part 4 supports most of the angular region where the guide frame 3 does not support the guide ring 2 and raises the holding force of the guide ring 2. Therefore, the guide ring 2 is held so as to be vertically held by the frame portion 30 of the guide frame 3 and the bridge part 4.

  In addition, the bridge part 4 compensates for the space between the guide frame 3 and the guide ring 2 at the two right and left places where the guide frame 3 is separated from the outer peripheral surface 2 b of the guide ring 2. Supplementation prevents yarn entanglement. That is, at two right and left locations where the left and right support leg portions 31 of the guide frame 3 are respectively separated from the outer peripheral surface 2 b of the guide ring 2, sharp valleys are formed between the support leg portion 31 and the outer peripheral surface 2 b of the guide ring 2. The V-shaped space is formed. The bridge part 4 compensates for the space at the two left and right places. Specifically, bridge part 4 has a pair of left and right filling portions 40 located in the space between guide frame 3 and guide ring 2 at two right and left places where guide frame 3 is separated from outer peripheral surface 2 b of guide ring 2. And a connecting portion 41 connecting the two filling portions 40 to each other.

  The bridge part 4 is composed of one member, so that the pair of right and left complementary parts 40 and the connecting part 41 between them are integrally formed. The compensating portion 40 is a separation point at which the guide frame 3 separates from the guide ring 2 in a front view as shown in FIG. 1 so that it can be inserted into the space corresponding to the space between the guide ring 2 and the guide frame 3. It has a tapered shape that gradually narrows toward P, and conversely, it becomes wider as it moves downward from the separation point P. The connecting portion 41 extends along the outer peripheral surface 2 b of the guide ring 2 so as to draw an arc. The dimension (thickness) in the radial direction of the guide ring 2 in the connection portion 41 is preferably smaller than the dimension in the direction of the center line 50 of the guide ring 2 in the connection portion 41, and the weight of the bridge part 4 can be reduced.

  The bridge part 4 includes an upper surface 42 located on the guide ring 2 side, a lower surface located on the opposite side of the guide ring 2, and a pair of left and right side surfaces 44. As viewed from the inside to the outside with respect to the center of the guide ring 2, the upper surface 42 of the bridge part 4 is the inner surface, and the lower surface of the bridge part 4 is the 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. Therefore, the upper surface 42 of the bridge part 4 has a shape along the outer peripheral surface 2 b of the guide ring 2, and a central angle corresponding to the angular range so as to be able to abut the predetermined angle range of the outer peripheral surface 2 b of the guide ring 2 It has a concave shape having a circular arc shape in a front view having the The angle range in which the upper surface 42 of the bridge part 4 abuts on the outer peripheral surface 2 b of the guide ring 2 is preferably less than 180 degrees.

  Further, the outer surface 2 b of the guide ring 2 can be sufficiently ensured in the contact area with the outer peripheral surface 2 b of the guide ring 2 in the cross sectional view cut along the radial direction of the guide ring 2. It is preferable that it is a cross-sectional shape corresponding to As described above, the circumferential groove 20 is formed on the outer circumferential surface 2 b of the guide ring 2. Therefore, the top 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 2 b of the guide ring 2 in a sectional view cut along the radial direction of the guide ring 2. Preferably, it is a convexly curved surface that is convexly curved toward the center of 2.

  The lower surface of the bridge part 4 is a surface located on the side upside down with the upper surface 42. The lower surface of the bridge part 4 corresponds to the outer peripheral surface 2 b of the guide ring 2, and an arc-shaped portion 43 a concentric with the upper surface 42 of the bridge part 4 and the guide ring 2. It is formed, and it has a pair of left and right curved surface portions 43b that are concavely curved 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 43 b of 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 approaching both ends in the left-right direction of the bridge part 4.

  The side surface 44 of the bridge part 4 abuts the inside of the support leg 31 of the guide frame 3. Preferably, an engaging groove (not shown) engageable with the guide frame 3 is formed on the side surface 44 of the bridge part 4. The engagement groove has an arc-shaped cross-sectional shape corresponding to a circle that is a cross-sectional shape of the hollow metal wire 34 in a cross-sectional view. The bridge part 4 abuts on the front area 31 a of the support leg 31 of the guide frame 3 which is an area located on the same plane as the frame 30 but does not abut on the intermediate area 31 b of the support leg 31. Therefore, the bridge part 4 can be formed into a plate shape having a constant thickness in the front-rear direction (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 one having a small specific gravity, and can be, for example, a hard resin or a fiber reinforced resin, and in particular, a fiber reinforced resin using carbon fiber as a reinforcing fiber is preferable. It is preferable that it is a formed resin molded product. The guide frame 3 may be made of metal such as titanium alloy.

  The fishing line guide 1 configured as described above is assembled and manufactured in the following order, for example. As described above, as shown in FIGS. 8 and 9, the guide ring 2 is manufactured from a metal plate 21 such as a titanium alloy. Then, as shown in FIG. 10, the bridge part 4 manufactured separately is united with the guide ring 2. In FIG. 10, as in FIG. 2, the guide ring 2 and the bridge part 4 are viewed from the rear side. 10 (a) shows the state before combining, FIG. 10 (b) shows the state after combining, and FIG. 10 (c) shows the main part of the state after combining partially the guide ring 2 only. It is The upper surface 42 of the bridge part 4 is brought into contact with the circumferential groove 20 of the outer peripheral surface 2 b of the guide ring 2 to bond and fix the bridge part 4 and the guide ring 2.

  On the other hand, as described above, the guide frame 3 is formed of one hollow metal wire. The guide ring 2 combined with the bridge part 4 is attached to the guide frame 3. The bridge part 4 and the guide ring 2 may be separately attached to the guide frame 3 separately. When mounting the guide ring 2 on the guide frame 3, as shown in FIG. 11A, the guide ring 2 is pushed forward from the rear side of the guide frame 3.

  The diameter G4 of the front flange 23 of the guide ring 2 is the outer diameter of the front end of the guide ring 2, and the diameter G3 of the rear flange 22 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 ridge 23 of the guide ring 2 is smaller than the diameter G3 of the rear ridge 22, but is larger than the inner diameter D of the frame 30 of the guide frame 3. Therefore, by pressing the guide ring 2 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 push it laterally. The frame portion 30 of the guide frame 3 is engaged with the circumferential groove 20 of the guide ring 2 by pushing 2 into the frame portion 30 of the guide frame 3. The frame 30 of the guide frame 3 has a C-shape opening downward, and the support legs 31 are also separated from each other on the left and right, so that the guide frame 3 engages with the circumferential groove 20 of the guide ring 2 Even in the configuration, by pushing in the guide ring 2, the guide frame 3 is elastically deformed so as to expand in diameter while opening in the left and right direction, and the guide ring 2 is received. Moreover, since the metal wire rod which comprises the guide frame 3 is circular in cross section, the guide ring 2 can be smoothly pushed into the frame portion 30 of the guide frame 3.

  Then, 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 the original state by its own elastic restoring force, 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 can be elastically deformed more easily than a 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 being elastically deformed so that the guide frame 3 is opened to the left and right, so that the support leg 31 of the guide frame 3 is engaged with the engaging groove of the side surface 44 of the bridge part 4. The front area 31a is in the engaged state. An adhesive may be used to attach the guide ring 2 and the bridge part 4 to the guide frame 3. The adhesive may be used as a supplement or, for example, may be configured to be adhesively fixed only by the adhesive without providing the circumferential groove 20 or the engagement groove.

  The fishing line guide 1 manufactured in this manner is attached to the outer peripheral surface of the rod 5 of the fishing rod as shown in FIG. Specifically, the mounting portion 32 of the fishing line guide 1 is placed on the rod body 5, and the winding thread 6 is wound around the mounting portion 32 and the rod body 5 to tie the fishing line guide 1 to the rod body 5. . More specifically, the winding thread 6 is wound from the rod 5 to the flat portion 32 c of the mounting portion 32 to fix the fishing line guide 1 to the rod 5. Furthermore, an adhesive synthetic resin (adhesive) is applied to the winding portion of the winding 6 and hardened. In the present embodiment, the guide ring 2 is in the upright posture in the attachment 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 inclined to the front side. It may be a forward-looking posture.

  In the fishing line guide 1 according to the present embodiment, since the flat portion 32c is formed at the rear of the attachment portion 32, compared to the case where the attachment portion 32 is in the shape of a hollow metal wire which is not crushed. The adhesion to the housing 5 is increased, and the winding thread 6 can be firmly wound on the flat portion 32c. Therefore, the fishing line guide 1 can be firmly attached to the rod 5. In particular, since the concave portion 38 is formed on the lower surface of the flat portion 32c, it is easier to follow along the housing 5 further compared with the case where the lower surface of the flat portion 32c is flat, and the adhesion is further enhanced. Since the concave portions 38 are continuous in the left-right direction so as to straddle the left and right metal wire rods at 32, good adhesion to the housing 5 is achieved even if the both end predetermined length regions of the metal wire rods are aligned horizontally Sex is secured. In addition, since both sides of the flat portion 32c are cut obliquely to the rear side and formed to be narrower toward the rear side, the wire 5 can be attached more firmly by the casing 5 It can be wound beautifully and a good appearance can be obtained.

  And, in the fishing line guide 1 attached to the housing 5 in this manner, since the guide frame 3 is made of metal wire, it is possible to compare to a configuration formed by punching a metal plate into a predetermined shape as in the prior art. Can easily be made lighter. Further, in the guide frame 3 in which the conventional metal plate is punched out, since the cross-sectional shape has an edge, the resistance when the fishing line comes in contact with the guide frame 3 is large, and thus yarn entanglement tends to occur. , Cast feel too bad. On the other hand, since the guide frame 3 of the fishing line guide 1 of this embodiment is formed of a metal wire rod having a circular cross section and has a circular cross-sectional shape without an edge, when the fishing line contacts the guide frame 3 The slipperiness of the fishing line is good and smooth, it is difficult for the line to be entangled, and the cast feel is also excellent.

  Furthermore, since the pair of left and right support leg portions 31 of the guide frame 3 is curved so as to expand outward in the left and right direction, the fishing line guide 1 is combined with the guide frame 3 having a circular cross section without edges. It is hard for the fishing line to get caught. Further, since the central angle θ of the frame portion 30 is smaller than the central angle α between the two contact points 54, the support leg portion 31 can be smoothly expanded from the end portion in the circumferential direction of the frame portion 30, There is no occurrence of a radially inward narrowing at the boundary between the portion 30 and the support leg 31, and the shape is smoothly continuous from the frame 30 to the support leg 31, further entanglement It is prevented.

  Further, even if the root region 31c of the support leg 31 is curved in the front-rear direction, the metal wire is maintained in the cross-sectional shape without being crushed in the root region 31c. The edgeless cross-sectional shape provides a good cast feel with less yarn contact, and yarn entanglement is further prevented. Further, since the metal wire is not crushed in the root region 31 c of the support leg portion 31, the strength is also 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 2 b of the guide ring 2 in the vicinity of the separation point P at the left and right two places where the guide frame 3 moves away from the outer peripheral surface 2 b of the guide ring 2 Therefore, it is possible to prevent the yarn entanglement that is likely to occur near the two separation points P by the bridge part 4. In particular, since the concave curved surface portion 43 b is formed on the lower surface of the filling portion 40 of the bridge part 4, yarn curving can be further suppressed by the curved surface portion 43 b.

  Furthermore, since the non-surrounding portion in which the frame portion 30 of the guide frame 3 is not circulated among the entire circumference of the guide ring 2 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 It is also held by the part 4 and the holding power 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 leg 31 of the guide frame 3 is also engaged with both side surfaces 44 of the bridge part 4, the guide ring 2, guide The frame 3 and the bridge part 4 are firmly integrated to further improve the strength of the fishing line guide 1. Further, by engaging the bridge part 4 with the circumferential groove 20 of the guide ring 2, the upper and lower dimensions of the bridge part 4 can be reduced and the weight can be reduced. In addition, since the bridge parts 4 connect the support leg portions 31 with each other within the range of the tip region 31a which is not curved in the front-rear direction, the bridge parts 4 are positioned on the same plane as the frame portion 30 of the guide frame 3 The size of the bridge part 4 in the front-rear direction can also be suppressed. By thus providing the bridge parts 4, it is possible to suppress an excessive increase in weight while achieving an increase in strength of the fishing line guide 1 and prevention of yarn entanglement.

  The fishing line guide 1 is provided with a cylindrical body 7 mounted on the outer peripheral surface of the rod 5 in addition to the configuration in which the winding guide 6 is fixed by winding 6 at a predetermined position on the outer peripheral surface of the rod 5 It may be one. That is, the cylindrical body 7 may be fixed to the outer peripheral surface of the housing 5 with an adhesive or the like, or may be freely covered. The fishing line guide 1 provided with the cylindrical body 7 may be a fixed guide in which the cylindrical body 7 is fixed to a predetermined position of the outer peripheral surface of the housing 5 or can freely move relative to the outer peripheral surface of the housing 5 It may be a floating guide. A fishing line guide 1 provided with such a tubular body 7 is used, for example, for a fishing rod.

  For example, as shown in FIGS. 12 and 13, the fishing line guide 1 includes a cylindrical body 7 externally mounted to the housing 5, and the guide frame 3 includes an attaching portion 32 for attaching to the cylindrical body 7; And a frame main body extending upward from the mounting portion 32, that is, radially outward from the cylindrical body 7. The frame main body similarly comprises a frame 30 and a pair of left and right support legs 31. The mounting portion 32 has a configuration of two legs divided into right and left, and is constituted by a predetermined length region of both end portions of the metal wire, and the outer peripheral surface of the cylindrical member 7 is divided into left and right respectively It is attached and fixed to the outer peripheral surface of. A circumferential groove may be formed on the outer peripheral surface of the cylindrical body 7 in which the attachment portion 32 is engaged, and the attachment portion 32 may be engaged with the circumferential groove. Moreover, in FIG.12 and FIG.13, although the both ends of a metal wire material are mutually spaced apart, the both ends of a metal wire material may be joined and the guide frame 3 may be formed in endless form. Thus, even if the fishing line guide 1 is configured to include the cylindrical body 7, the support legs 31 extend in a straight line if the left and right support legs 31 have a curved shape expanded outward in the left-right direction. As compared with the case of the above, yarn entanglement can be prevented.

  Further, the attachment portion 32 may be configured to be attached to the tubular body 7 as a configuration of two legs instead of the configuration in which the attaching portion 32 goes around the outer peripheral surface of the tubular body 7. For example, as shown in FIG. 14, the pair of left and right attachment portions 32 may be separated and independent from each other to the left and right, and may be attached and fixed to the outer peripheral surface of the cylindrical body 7 respectively. The attachment configuration of the attachment portion 32 to the cylindrical body 7 is arbitrary, and for example, the attachment portion 32 consisting of an end predetermined length region of the metal wire may be simply adhered and fixed to the outer peripheral surface of the cylindrical body 7 Alternatively, as shown in FIG. 14, a pair of fixing holes 70 may be formed on the outer peripheral surface of the cylindrical body 7, and the mounting portions 32 may be inserted into and fixed to the pair of fixing holes 70. Preferably, a protrusion 71 is formed on the outer peripheral surface of the cylindrical body 7 and a fixing hole 70 opened on the front side, for example, is formed in the protrusion 71 along the front-rear direction.
