Description

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

  There are various types of so-called outer guide type fishing rods in which a fishing line guide is mounted on the outside of the fishing rod. Such a fishing line guide includes a guide ring for guiding the fishing line and a guide frame for holding the guide ring. A ring mounting hole is formed in the guide frame, and the guide ring is inserted into the ring mounting hole along the direction of the center line of the ring mounting hole and fixed by an adhesive. Then, the fishing line is inserted through the guide ring of the fishing line guide and guided. Since a large force acts on the guide ring from the fishing line, it is necessary to firmly bond the guide ring to the guide frame.

  Patent Document 1 below discloses a configuration in which a cylindrical portion is provided on a guide frame, and a guide ring is fitted on the inner peripheral surface thereof and fixed with an adhesive. In this case, since there is no portion where the adhesive accumulates on the inner peripheral surface of the cylindrical portion, if the amount of adhesive applied is increased in order to firmly bond the adhesive, the adhesive is greatly increased on the front side or rear side of the guide ring. The fishing line may protrude and the fishing line may come into contact with the protruding adhesive. Therefore, it is difficult to firmly fix the guide ring by increasing the adhesion amount of the adhesive.

  Further, Patent Document 2 below proposes a shape that is expanded in a tapered shape from the middle part of the wall surface of the ring mounting hole toward the front side and the rear side. And while the middle part contacts the outer peripheral surface of the guide ring with a point or a line, a gap is formed between the tapered parts on both sides of the guide ring and the outer peripheral surface of the guide ring, and the gap is filled with adhesive. Is done.

  In this configuration, adhesive can be filled in the tapered portions on both the front and rear sides of the wall surface of the ring mounting hole, but the guide ring contacts the middle portion of the wall surface of the ring mounting hole with dots or lines. When inserting the guide ring into the ring mounting hole, the guide ring tends to tilt, and it is difficult to accurately assemble the guide ring to the guide frame. As a result, the guide ring cannot be firmly fixed to the guide frame.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fishing line guide, a fishing rod, and a guide frame for a fishing line guide capable of firmly and accurately mounting a guide ring.

  The present invention has been made to solve the above problems, and a fishing line guide according to the present invention is a guide frame in which a guide ring for guiding a fishing line and a ring mounting hole in which the guide ring is mounted are formed. A spiral line guide is provided, wherein a spiral groove is formed in a wall surface of the ring mounting hole along a circumferential direction of the wall surface.

  In the fishing line guide having such a configuration, since the spiral groove is formed on the wall surface of the ring mounting hole, the adhesive can be stored in the spiral groove. That is, a spiral groove can be used as an adhesive pool. Therefore, the guide ring can be firmly adhered and fixed to the guide frame with a large amount of adhesive. Further, since the portion of the wall surface of the ring mounting hole other than the spiral groove is a flat surface along the axial direction of the ring mounting hole, the guide ring can be accurately inserted into the ring mounting hole. That is, since the wall surface of the ring mounting hole is a combination of a flat surface and a groove along the axial direction, the guide ring can be accurately inserted into the ring mounting hole using the flat surface as a guide surface. Adhesive can be stored in the spiral groove.

  In particular, the spiral groove is preferably formed over the entire length in the axial direction of the wall surface of the ring mounting hole, so that the length of the spiral groove can be sufficiently secured and the amount of the adhesive can be secured. Cheap. Further, since the spiral groove reaches one end and the other end of the wall surface of the ring mounting hole, the air in the spiral groove is easily discharged to the outside from the one end and the other end of the spiral groove. Air hardly remains in the groove. Therefore, the adhesive can be easily stored in the spiral groove.

  Moreover, it is preferable that the spiral groove is formed two or more times, so that the length of the spiral groove can be sufficiently secured and a large amount of adhesive can be stored.

  The fishing rod according to the present invention includes such a fishing line guide.

  A guide frame for a fishing line guide according to the present invention is a fishing line guide guide frame having a ring mounting hole to which a guide ring for guiding a fishing line is mounted. A spiral groove is formed along the circumferential direction.

  As described above, since the spiral groove is formed in the wall surface of the ring mounting hole, the guide ring can be mounted firmly and accurately on the guide frame.

<Overall configuration>
Hereinafter, a fishing line guide guide frame and a fishing line guide using the same according to an embodiment of the present invention will be described with reference to FIGS. The guide frame of the fishing line guide in this embodiment is shown in FIGS. 1-7, and the principal part of the fishing line guide using it is shown in FIG. The fishing line guide includes a guide ring 2 for directly guiding the fishing line and a guide frame 3 for holding the guide ring 2.

  The fishing line guide is attached to the outside of the housing 4. The guide frame 3 includes an attachment portion 11 for attachment to the housing 4 and a frame main body portion 12 erected from the attachment portion 11. The attachment portion 11 is cylindrical and has a structure in which the housing 4 is inserted inside. The fishing line guide may be a floating type, that is, a so-called floating guide (moving guide) in which the attachment portion 11 is movable with respect to the rod body 4 and is fixed by friction at a predetermined position. A fixed type, that is, a so-called fixed guide that is fixed to a predetermined position such as the tip of the body 4 may be used.

  Note that the heel side is referred to as the front side, the buttock side is referred to as the rear side, and in the frame main body portion 12, the direction away from the attachment portion 11 is referred to as the upper side, and the direction approaching the attachment portion 11 is referred to as the lower side. Therefore, the distal end side of the guide frame 3 is the upper side, and the proximal end side is the lower side.

<Guide ring 2>
The guide ring 2 is, for example, a circular ring shape, but the shape thereof is arbitrary and may be an oval shape, an oval shape, or the like, and in any case, it is a ring shape (annular shape). Hereinafter, the case where the guide ring 2 is circular will be described. The guide ring 2 is made of a hard material having excellent wear resistance such as ceramic represented by SiC (silicon carbide), for example, and has a thread insertion hole through which a fishing line is inserted, and the fishing line slides on the inner peripheral surface. The fishing line is guided directly by moving. In addition, the outer peripheral surface of the guide ring 2 constitutes a portion between the curved chamfered portions formed at both ends and the double-sided chamfered portions, and is a straight circle extending in the direction of the center line with a constant diameter. The straight portion is in surface contact with the fitting surface portion 20 on the wall surface of the ring mounting hole 10 of the guide frame 3. The dimension of the guide ring 2 in the direction of the center line is larger than that of the frame main body 12 of the guide frame 3. Therefore, when the guide ring 2 is attached to the frame body 12, the guide ring 2 protrudes from the front surface 12 a and the rear surface 12 b of the frame body 12.

<Mounting part 11 of guide frame 3>
The guide frame 3 includes an attachment portion 11 for attachment to the housing 4 and a frame main body portion 12 erected radially outward from the attachment portion 11. The attachment part 11 is formed in a cylindrical shape, and the housing 4 is inserted inside thereof. That is, the attachment portion 11 has a collar insertion hole 13 into which the chassis 4 is inserted. The eaves insertion hole 13 is a through hole that is open at both ends, and the enclosure 4 is inserted into the eaves insertion hole 13. Therefore, the center line 13 a of the collar insertion hole 13 coincides with the center line of the chassis 4. The fishing line guide in the present embodiment is movable in the front-rear direction with respect to the housing 4 and can be rotated around the axis, and can be fixed at a predetermined position by friction with the outer peripheral surface of the housing 4. Although it is a so-called floating guide (moving guide), it may be a so-called fixed guide that is fixed to a predetermined position on the outer peripheral surface of the casing 4 so as to be immovable by adhesion or the like. An enlarged diameter portion 13b is formed at the front end portion and the rear end portion of the eaves insertion hole 13 so as to increase in diameter toward the opening. Further, a concave recessed portion 13c is locally formed in the upper part of the entire circumference of the front end opening edge of the collar insertion hole 13.

  The shape of the outer peripheral surface of the mounting portion 11 is different between the front portion and the rear portion, and the front portion is a straight shape having a substantially constant diameter, while the rear portion is a reverse tapered shape that gradually decreases in diameter toward the rear side. . Specifically, the rear portion of the outer peripheral surface of the attachment portion 11 has a so-called reverse shell type that has a small diameter toward the rear side while curving in a convex shape toward the radially outer side. Note that the rear end of the outer peripheral surface of the attachment portion 11 reaches the rear end opening edge of the collar insertion hole 13.

  Further, the frame main body 12 extends upward from the front end portion of the outer peripheral surface of the mounting portion 11, but at the upper part of the outer peripheral surface of the mounting portion 11 and on the rear side of the frame main body 12, A thinned portion 14 that is locally thin in the entire circumference is formed. The thinned portion 14 has a shape obtained by scraping the outer peripheral surface of the mounting portion 11 at a certain depth, and extends along the direction of the center line of the housing 4 from the lower end of the rear surface 12b of the frame main body portion 12 toward the rear side. It extends with a certain width.

  The front end surface 11a of the mounting portion 11 may be a surface orthogonal to the center line 13a of the flange insertion hole 13, but in this embodiment, from the upper side to the lower side as shown in FIGS. The slanted surface is inclined rearward. On the other hand, the rear end of the attachment portion 11 is a rear end opening edge of the eaves insertion hole 13, and the rear end opening edge is orthogonal to the center line 13 a of the eaves insertion hole 13.

<Frame body 12 of guide frame 3>
The frame main body 12 extends upward from the front end of the attachment portion 11, and a ring mounting hole 10 for mounting the guide ring 2 to the frame main body 12 is formed. The frame main body 12 is a thin plate in the front-rear direction, and the dimension in the left-right direction varies depending on the outer diameter of the guide ring 2 to be mounted, and thus varies depending on the diameter of the ring mounting hole 10.

  Further, as shown in FIGS. 2 and 6, the frame main body 12 is tilted to the front side by a predetermined angle. That is, when the case where the frame main body portion 12 stands up at a right angle to the center line 13a of the flange insertion hole 13 is taken as a reference, the frame body portion 12 stands up at a predetermined angle from the reference state, that is, in a forward leaning posture. ing. Although the inclination angle from the upright state is arbitrary, it is, for example, 45 degrees or less, preferably 10 to 40 degrees, and more preferably 20 to 30 degrees. The ring mounting hole 10 is formed along the thickness direction of the frame main body portion 12 as the plate-shaped frame main body portion 12 is inclined to the front side by a predetermined angle. Therefore, the center line 10 a of the ring mounting hole 10 is not parallel to the center line 13 a of the heel insertion hole 13, and the front side is closer to the center line 13 a of the heel insertion hole 13 with respect to the center line 13 a of the heel insertion hole 13. It is inclined to. The inclination angle of the frame main body portion 12 from the standing state to the front side is an angle between the center line 13 a of the collar insertion hole 13 and the center line 10 a of the ring mounting hole 10. As described above, the front end surface 11a of the attachment portion 11 is an inclined surface inclined obliquely rearward from the upper side to the lower side. The inclination angle of the front end surface 11a of the attachment portion 11 and the frame body The inclination angle of the portion 12 may be the same or different. That is, the front end surface 11a of the mounting portion 11 and the front surface 12a of the frame main body portion 12 may be the same plane. However, in this embodiment, the frame main body portion 12 has an inclination angle that is greater than the inclination angle of the front end surface 11a of the mounting portion 11. The inclination angle of the front surface 12a is larger. Therefore, the front surface 12a of the frame main body 12 is bent forward with respect to the front end surface 11a of the mounting portion 11.

  The ring mounting hole 10 passes through the frame main body 12. As shown in FIGS. 6 and 7, a spiral groove 21 is formed on the wall surface of the ring mounting hole 10. Therefore, the wall surface of the ring mounting hole 11 has a fitting surface portion 20 that is a straight columnar surface extending along the direction of the center line 10a, and a spiral shape that is recessed radially outward with respect to the fitting surface portion 20. The groove 21 is constituted. In this embodiment, since the guide ring 2 is circular, the ring mounting hole 10 is also circular. Therefore, the fitting surface portion 20 is a cylindrical surface having a constant diameter. As shown in FIG. 8, the guide ring 2 is press-fitted into the ring mounting hole 10, but the outer peripheral surface of the guide ring 2 comes into surface contact with the fitting surface portion 20. Therefore, the fitting surface portion 20 has the same diameter as the outer peripheral surface of the guide ring 2. The fitting surface portion 20 is formed from the front end portion to the rear end portion of the ring mounting hole 10.

  The spiral groove 21 has a shape that is recessed radially outward from the fitting surface portion 20. Therefore, when the guide ring 2 is mounted in the ring mounting hole 10, a gap is formed between the spiral groove 21 and the outer peripheral surface of the guide ring 2. The spiral groove 21 is filled with an adhesive. That is, the spiral groove 21 is used as an adhesive pool. The spiral groove 21 is formed from the front end portion to the other end portion of the wall surface of the ring mounting hole 10. Therefore, the spiral groove 21 is formed over the entire length of the wall surface of the ring mounting hole 10 in the axial direction. ing. The spiral groove 21 extends to the front side while rotating in the circumferential direction starting from a predetermined portion of, for example, the entire circumference of the rear end portion of the wall surface of the ring mounting hole 10, and at least two on the wall surface of the ring mounting hole 10. After the rotation, a predetermined portion of the entire circumference of the front end portion of the wall surface of the ring mounting hole 10 is set as the end point. The spiral groove 21 is preferably formed for at least two rotations, but is formed for three rotations in this embodiment. The pitch of the spiral grooves 21 is also arbitrary, but it is preferable that the pitch be formed at the wall surface of the ring mounting hole 10 two or more times. The depth of the spiral groove 21 is, for example, 0.1 to 0.5 mm. Although the cross-sectional shape of the spiral groove 21 may be various, for example, the spiral groove 21 has an inverted triangular shape that becomes narrower as the depth increases.

  Chamfered curved surfaces 12d and 12e between the upper end surface 12c and the front surface 12a of the frame main body 12 and between the upper end surface 12c and the rear surface 12b of the frame main body 12 as shown in FIGS. Is formed. The front and rear chamfered curved surfaces 12d and 12e are both curved surfaces that are curved in the front-rear direction in a cross-sectional view. Is smaller than That is, the front curved surface 12d is relatively large, and therefore, the boundary portion between the upper end surface 12c and the front surface 12a of the frame main body 12 is greatly chamfered, while the rear curved surface 12e is relatively Therefore, the boundary portion between the upper end surface 12c and the rear surface 12b of the frame main body 12 is chamfered small.

  Further, a hollowing recess 16 is formed in the lower portion of the front surface 12a of the frame main body 12. The lightening recess 16 is located at the center in the left-right direction below the front surface 12 a of the frame body 12, and is located in the middle between the ring mounting hole 10 and the heel insertion hole 13. It is located immediately above the escape portion 13c. The lightening recesses 16 are not through-holes but are not through-holes, and the number and shape of the front view are arbitrary, but it is preferable to provide one with a long shape in the left-right direction. Further, the depth of the recess 16 for removing the meat based on the front surface 12a of the frame main body 12 may be arbitrary and constant, but it is preferable that the upper portion is deep and the lower portion is shallow, It is preferable that the depth be gradually reduced from the upper side to the lower side. That is, it is preferable that the bottom surface of the hollowing recess 16 is not inclined but is orthogonal to the center line 13 a of the heel insertion hole 13.

  On the other hand, side reinforcing wall portions 17 are formed on both left and right side portions of the lower portion of the rear surface 12b of the frame main body portion 12, respectively. The side reinforcing wall portion 17 is formed so as to connect the rear surface 12b of the frame main body portion 12 and the outer peripheral surface of the mounting portion 11 as shown in FIGS. The dimension in the front-rear direction of the side reinforcing wall portion 17 gradually increases toward the lower side. Therefore, the side reinforcing wall portion 17 is obliquely downward from the rear surface 12b of the frame main body portion 12 to the outer peripheral surface of the mounting portion 11. The lower end of the side reinforcing wall portion 17 reaches the center portion in the front-rear direction of the outer peripheral surface of the mounting portion 11. Further, as shown in FIG. 3, when viewed from the rear along the center line 13 a of the flange insertion hole 13, the side reinforcing wall portion 17 is vertically long and narrower toward the upper side, that is, away from the attachment portion 11. The width is wider toward the lower side, that is, closer to the mounting portion 11. The length of the side reinforcing wall portion 17 in the vertical direction is arbitrary, but in this embodiment, the side reinforcing wall portion 17 extends from the outer peripheral surface of the mounting portion 11 to the positions on the left and right sides of the lowermost portion of the ring mounting hole 10, and the height of the upper end 17a thereof. Is substantially equal to the height of the lowermost portion of the ring mounting hole 10. Note that the above-described thinned portion 14 is located between the left and right side reinforcing wall portions 17.

  The material of the guide frame 3 configured as described above is arbitrary and may be made of metal or synthetic resin, but is preferably made of synthetic resin. In particular, it is preferably made of fiber reinforced resin, and is preferably a synthetic resin mixed with short fibers having a length of 1 mm or less. The length of the short fiber is particularly preferably 0.5 mm or less. The guide frame 3 can be integrally formed by injection molding, and can be an injection-molded product made of one member. The material of the guide frame 3 may be various thermoplastic resins suitable for injection molding. The short fiber may be carbon fiber or the like. When the guide frame 3 is formed by injection molding, both the flange insertion hole 13 and the ring mounting hole 10 may be formed by injection molding. However, while the flange insertion hole 13 is formed by injection molding, the ring mounting hole 10 It is preferable to form by punching in the semi-finished product after molding rather than by injection molding. When the wall surface of the ring mounting hole 10 is formed by cutting rather than injection molding, the adhesion between the fitting surface portion 20 and the outer peripheral surface of the guide ring 2 is improved. In addition, the spiral groove 21 is preferably formed by post-processing on the fitting surface portion 20 after the entire wall surface of the ring mounting hole 10 is formed as the fitting surface portion 20 that is a straight portion. Can be formed.

  In the fishing line guide having the guide frame 3 as described above, since the spiral groove 21 is formed in the wall surface of the ring mounting hole 10, the adhesive can be stored in the spiral groove 21. That is, the spiral groove 21 can be used as an adhesive pool. Therefore, the guide ring 2 can be firmly bonded and fixed to the guide frame 3 with a large amount of adhesive. Further, the portion of the wall surface of the ring mounting hole 10 other than the spiral groove 21 is a fitting surface portion 20 that is a flat surface along the axial direction of the ring mounting hole 10. The guide ring 2 can be accurately inserted into the ring mounting hole 10 as a guide surface, and the inclination of the guide ring 2 can be prevented. In particular, since the fitting surface portion 20 is formed from the front end portion to the rear end portion of the wall surface of the ring mounting hole 10, the guide ring 2 can be accurately press-fitted. Even if the spiral groove 21 is formed on the wall surface of the ring mounting hole 10, the length region of more than half of the entire length of the wall surface is constituted by the fitting surface portion 20. Guidance can be made accurately and the tilt can be prevented. Since the adhesive can be stored in the spiral groove 21, the guide ring 2 can be adhered and fixed accurately and firmly.

  Further, since the spiral groove 21 is formed over the entire length in the axial direction of the wall surface of the ring mounting hole 10 and formed twice or more, the length of the spiral groove 21 is sufficiently ensured. be able to. Therefore, a large amount of adhesive can be stored in the spiral groove 21, and sufficient adhesive strength can be ensured. Further, the spiral groove 21 is not formed only in the midway portion in the axial direction of the wall surface of the ring mounting hole 10, but one end portion and the other end portion thereof are the front end portion and the rear portion of the wall surface of the ring mounting hole 10, respectively. Since it is located at the end, the air in the spiral groove 21 is easily discharged, and the air hardly remains in the spiral groove 21. Therefore, the adhesive can be easily stored in the spiral groove 21 and desired adhesive strength can be easily obtained.
