Description

  The present invention relates to a method for manufacturing a fishing line guide that is attached to a fishing rod and guides a fishing line fed from a reel.

  Conventionally, a fishing line guide for inserting and guiding a fishing line fed from a reel at a predetermined interval in the axial direction is mounted on an outer peripheral surface of a fishing rod called an outer guide method. Many of such fishing line guides are constituted by a frame having an annular holding portion and a supporting leg portion, and a guide ring attached to the annular holding portion.

  For example, Patent Document 1 discloses a fishing line guide having a structure in which a guide ring is caulked into a grooved metal fitting and attached to a snap ring (a frame having a support leg). The ferrule is constituted by a wire, and a lower portion of the ferrule is separated to form a notch, and the guide ring (grooved metal fitting) is attached by expanding the ferrule at this portion.

Utility Model 1-99152

  In the known guide ring described above, a notch is formed by notching a part of the lower part of the ring-shaped ferrule, and when the final fishing line guide is manufactured, the ferrule is widened and the guide ring is expanded. Since the (grooved metal fitting) is attached, there is a possibility that a portion far from the notch portion of the ferrule (the upper portion of the ferrule) is deformed and opened at a time. In other words, since the frame may be plastically deformed, it may be difficult to mount the guide ring or the guide ring may not be sufficiently held.

  The present invention has been made paying attention to the above-described problem, and a fishing line guide manufacturing method in which a guide ring can be easily attached to an annular holding portion of a frame that holds the guide ring, and the guide ring is securely held. The purpose is to provide.

  In order to achieve the above-described object, the present invention provides a fishing line guide manufacturing method in which a guide ring is attached to an annular holding portion of a frame, and a holding portion in which the notch portion is formed and the notch portion is formed in the holding portion. Both ends of the part are formed in a tapered shape, both ends of the holding part are elastically deformed, and a guide ring is press-fitted inside the holding part.

  In the method for manufacturing a fishing line guide having the above-described configuration, the guide ring is press-fitted into the annular holding portion of the frame. At this time, since both end portions of the annular holding portion are tapered toward the tip, it is possible to be elastically deformed and distorted when the guide ring is press-fitted, thereby easily press-fitting the guide ring. be able to. Further, when the guide ring is finally press-fitted into the annular holding portion, the bent holding portion can be elastically restored, so that the guide ring is sufficiently fixed.

  According to the method for manufacturing a fishing line guide of the present invention, the guide ring can be easily attached to the annular holding portion of the frame that holds the guide ring, and a fishing line guide in which the guide ring is securely fixed can be obtained.

Hereinafter, an embodiment of a method for manufacturing a fishing line guide according to the present invention will be specifically described.
1 to 4 are views showing an embodiment of a fishing line guide manufactured by the manufacturing method of the present invention. FIG. 1 is a rear view, FIG. 2 is a side view showing a guide ring mounting method, and FIG. FIG. 4 is a rear view showing the frame structure of the fishing line guide shown in FIG. 1, and FIG. 4 is a side view of the fishing line guide shown in FIG. In FIG. 2, the left side is the tip side (front side), and the right side is the hand side (rear side).

  The fishing line guide 1 includes a frame 2 having an annular holding portion 2a and a support leg portion 2b, and a guide ring 10 attached in the holding portion 2a.

  The frame 2 can be integrally formed of, for example, titanium (pure Ti), various known titanium alloys, stainless steel, and the like, and as described above, the annular holding portion 2a and the annular holding portion 2a. And a supporting leg 2b extending downward from the holding portion. The support leg portion 2b supports the annular holding portion 2a on both sides in the radial direction, and a pair of leg portions 2d extending so as to approach each other downward on each side portion, and a pair of leg portions The lower end of 2d has a foot 2e bent in a substantially horizontal direction. The foot portion 2e has a mounting surface 2f for a fishing rod on the back side thereof, and the foot portion is fixed to the outer peripheral surface of the fishing rod R with a spool 7 or the like. In addition, after thread winding 7, a resin 8 for thread fixing is attached.

  The annular holding portion 2a of the frame 2 has a width L1 larger than its thickness L2, and has a circular hole 3 to which the guide ring 10 is attached. In addition, the annular holding portion 2a is cut at an arbitrary position (in this embodiment, the lower end position as shown in FIG. 1) with a predetermined gap, so that the hole 3 is formed from the outside. A notch portion 4 is formed which leads to. In the figure, each of the ends (claw-like projections) of the cut annular holding portion 2a is indicated by reference numeral 4a. The notch portion 4 has a front end surface 4b of both end portions 4a with a predetermined gap. It is formed by facing each other. The thickness L2 of the holding portion 2a of the frame 2 is the thickness (length) in the front-rear direction in which the fishing line is inserted by attaching the fishing line guide 1 to the fishing rod, and the width L1 is the radial width of the annular holding portion 2a. (Length).

  The both end portions 4a are formed in a tapered shape. Here, as shown in FIG. 1, the tapered shape is one in which the width L1 decreases as it moves to the tip in front view, the thickness L2 decreases as it moves to the tip, or as it moves to the tip. Any one that is configured such that the rigidity becomes smaller as it moves to the tip, such as both the width and the thickness become smaller, and it becomes easier to bend toward the tip (tip surface 4b side). In the present embodiment, as shown in FIG. 1, the lower edges 4 c constituting the respective end portions 4 a extend in a substantially horizontal direction, and the upper edge is configured as an arc that defines the hole 3. It has a tapered shape. In the present embodiment, the rear surface 4d and the front surface 4e at both end portions 4a are also closer to each other as they move to the front end, and the thickness is reduced, resulting in a tapered shape (see an enlarged view of FIG. 4).

  In addition, the frame 2 is formed with a large width L1 of the holding portion 2a connected to the portion where the cutout portion 4 is formed (both end portions 4a) in the range from the holding portion 2a to the left and right support legs 2b. An extended portion 2A is formed. In the present embodiment, as described above, since the cutout portion 4 is the lower end position of the holding portion 2a, the extension portion 2A is positioned on both the left and right sides of the holding portion 2a (holding portion) as shown in FIG. It is gradually formed wider from a horizontal side position passing through the center position of 2a; indicated by a symbol P) toward a lower position where the notch 4 is formed. In the drawing, such an extended portion is indicated by a shaded portion, a holding portion 2a adjacent to the extended portion 2A is indicated by a hatched portion as a region 2a 'extended by a certain width L1, and a virtual boundary with the extended portion 2A is indicated. It is indicated by a two-dot chain line. The lower end side of the extended portion 2A is a boundary position P1 between the pair of leg portions 2d. That is, the range from the reference symbol P to P1 is defined as the extended portion 2A, and the extended portion 2A has a function of reinforcing both end portions 4a forming the cutout portion 4.

  The extension part 2A is narrowed so that both sides thereof are narrowed from the holding part 2a toward the support leg part 2b and displaced to the support leg part 2b (or the support leg part 2b spreads toward the holding part 2a). The expanded portion 2A is formed with the largest width L1 on the center side toward the support leg portion 2b, and one side thereof is connected to the end portion 4a, and the width L1 gradually increases from the end portion 4a toward the support leg portion 2b.

  The frame 2 having the annular holding portion 2a and the support leg portion 2b is formed by punching a metal plate into a predetermined shape by press working and bending a predetermined portion. Therefore, each part of the frame 2 has a part formed by the upper and lower surfaces of the metal plate to be pressed and a part formed by the cut surface, and is the front and rear surfaces (the tip side surface and the hand side surface) of the frame 2. (For example, the front surface 4e and the rear surface 4d also correspond) are formed by the upper and lower surfaces of the metal plate, and the thickness portion of the side surface of the frame 2 is formed by the cut surface of the metal plate.

  The guide ring 10 is a circular ring formed of a hard material such as metal or ceramic. A pair of flanges 10a and 10b are formed along the outer periphery, and a recess (circumferential groove) 10c is formed between the flanges. It has a structure.

  In the present embodiment, one (flange 10b) of the pair of flanges is formed high, and the holding portion 2a is engaged (fitted) with a recess 10c formed between the pair of flanges. Alternatively, the guide ring is held by engaging (abutting) with the flange, and in this state, the adhesive is filled to prevent the guide ring from rotating. In such a fixed state of the guide ring, as shown in FIG. 1, the ends of both end portions 4a of the holding portion 2a are located on the radially inner side of the peripheral edge of the flange (the flange 10b having a high height). Since it does not protrude to the outside of the flange, the fishing line is prevented from being caught and the thread breakage or the like is prevented from occurring.

  The guide ring 10 is formed to have a larger diameter than the holding portion 2a. Preferably, the guide ring 10 has an inclined portion (curved in a sectional view) at the periphery thereof, specifically, the periphery of the flange 10a on the press-fitting side. An inclined portion) 10e is formed.

  FIG. 5 shows a case where the fishing line guide 1 having the above-described configuration is manufactured manually, and shows a state of elastic deformation of the frame when the guide ring is press-fitted.

  When the guide ring 10 is mounted in the annular holding portion 2a, the guide ring 10 is brought close to the front of the fishing line guide 1 and the guide ring 10 is inserted into the holding portion 2a from the flange 10a side with a low height. Face each other so that they face each other and press-fit in the front-rear direction (fishing line insertion direction). In this case, in the embodiment, the guide ring is press-fitted from the front, but the guide ring may be oriented in either the front or rear direction. The guide ring 10 may be pressed from the flange 10a side with the low height of the guide ring 10 and attached. good.

  As described above, the guide ring 10 is formed to have a larger diameter than the holding portion 2a, and the inclined portion 10e is formed on the periphery of the flange 10a on the press-fitting side. Is elastically deformed so that the plate-like front surface 2p faces inward while spreading along the inclined portion 10e (see the enlarged view on the upper side of FIG. 5).

  At this time, as for the holding | maintenance part 2a, the both ends 4a which prescribe | regulate the notch part 4 are the most elastically deformed. In particular, since the holding portion 2a is formed to have a width larger than its thickness, the both end portions 4a are easily bent in the pressing direction (rearward) toward the tip, and the front side is pushed so that the inside of the hole is pushed. Since it is elastically deformed so as to open outward while facing (see the enlarged view on the lower side of FIG. 5), press-fitting can be easily performed. And if the front-end | tip of the both ends 4a which define the notch part 4 gets over the flange 10a of the guide ring 10, elastic deformation will be cancelled | released and it will engage with the recessed part 10c between flanges, restoring | restoring. Thereafter, the guide ring 10 is easily fitted into the inside of the hole of the holding portion 2a by press-fitting because the entire holding portion is guided by the engagement of the concave portion 10c and is engaged with the concave portion 10c between the flanges. Retained.

  In the method for manufacturing a fishing line guide as described above, both end portions 4a of the annular holding portion 2a are tapered toward the tip, so that when the guide ring 10 is press-fitted, it is gradually elastically deformed toward the tip. Thus, the guide ring can be easily press-fitted. Further, when the guide ring 10 is finally press-fitted into the annular holding portion 2a, the holding portion 2a is plastically deformed and is not easily distorted, so that the holding portion 2a is reliably engaged with the concave portion 10c, and the guide ring 10 is sufficiently Will be held in. In particular, since both end portions 4a are tapered toward the tip, the tip side is bent, and the base portion side (the leg 2d side) opposite to the tip is difficult to be plastically deformed.

  In this case, an adhesive is applied to the concave portion 10c of the circumferential groove or the inner surface of the hole 3 of the holding portion 2a, so that the guide ring 10 is firmly fixed to the holding portion 2a. good.

  In addition, when the both end portions 4a are elastically deformed during the press-fitting operation, the frame portion is prevented from being plastically deformed and further extended from the expanded portion 2A. The left and right support legs 2b can assist the restoration by pushing back the extended holding part 2a.

  In the state where the guide ring is attached (held), as shown in FIG. 1, the tips of both end portions 4a of the holding portion 2a are located radially inside the peripheral edge of the flange (the flange 10b having a high height). Since it does not protrude to the outside of the flange, the fishing line is prevented from being caught and the thread breakage or the like is prevented from occurring. Even if tension is applied to the inserted fishing line, both ends 4a of the holding portion 2a are distorted while being greatly elastically deformed toward the tip, so that the frame itself is difficult to deform and the tension on the fishing line is reduced. The thread breakage is prevented, and the dropout of the guide ring 10 can be effectively suppressed.

  Moreover, since the flange is formed in the guide ring 10 along the outer periphery and the both end portions 4a having the tapered shape of the holding portion 2a are engaged with the flange, the guide ring 10 from the holding portion 2a is engaged. The falling off is effectively prevented, and the both ends 4a are reliably inserted by the flange by the load on the guide ring 10 to be elastically deformed to relieve the tension on the fishing line.

  Although the above-described method for manufacturing a fishing line guide is performed manually, it can also be manufactured using a mold. 6 to 8 are diagrams showing a method of press-fitting a guide ring into a frame using a mold, FIG. 6 (a) is a diagram showing a state before press-fitting, and FIG. 6 (b) is press-fitting. FIG. 6C is a diagram showing a state where the press-fitting is completed. 7 is a view showing a modification of the fishing line guide in the manufacturing method shown in FIG. 6, a view showing a portion of the annular holding portion of the frame, and FIG. 8 is a partial cross section of the fishing line guide shown in FIG. FIG.

  When using a mold, as shown in FIG. 6 (a), a pair of flanges 10a, 10a, and 10b are mounted on the holding portion 2a in a state where the frame 2 is placed on the lower mold 30 having the circular recess 30a. The lower flange 10a side of the guide ring 10 having 10b is placed and placed, and pressed by the plate-shaped upper mold 31 from the higher flange 10b side.

  When the upper die 31 is pressed toward the lower die 30, as shown in FIG. 6B, the holding portion 2 a is the most elastically deformed at both end portions 4 a defining the notch portion 4 as in the above-described embodiment. As it becomes the tip, it bends in the pressing direction. Then, when the tips of both end portions 4a get over the flange 10a of the guide ring 10, the elastic deformation is released, and as shown in FIG. 6C, the guide ring 10 is engaged with the recess 10c between the flanges while being restored. It is easily fitted and held by press fitting inside the hole of the holding portion 2a.

  In this way, the fishing line guide can be manufactured using a mold, not manually.

  In the above-described configuration, both end portions 4a may be configured to be plastically deformed when the upper die is press-fitted. Specifically, both end portions 4a are bent before press-fitting, or both end portions 4a are formed so as to be plastically deformable along the press-fitting direction with respect to their rigidity, as shown in FIG. Accordingly, as shown in FIG. 7, when the press-fitting is completed, the holding portion 2 a in the region of both end portions 4 a can be deformed and brought into contact with the recess 10 c of the guide ring 10. That is, both sides of the frame are pressed against the inner surface (the inner surface 10a 'on the lower flange side) with which the tip of the holding portion in the recess 10c comes into contact and the inner surface on the opposite side (the higher flange side 10b'). Therefore, the guide ring 10 can be held more reliably.

  In this manner, since both end portions 4a are tapered, it is possible to easily bend the end portions (on the front end surface 4b side).

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, the construction material of the frame constituting the fishing line guide, the configuration of the shape and size of the frame portion, and the like are appropriately modified according to the fishing rod and node portion (general rod, middle rod, tip rod) in which it is used. It is possible.

  Further, the guide ring may be formed with a flange on only one side, or the flange configuration can be modified as appropriate as long as it can be effectively press-fitted into the holding portion 2a. Furthermore, as long as both ends 4a of the holding portion 2a are configured to be able to bend in the press-fitting direction when the guide ring is press-fitted, the specific shape can be appropriately modified.
