Description

  The present invention relates to a floating fishing line guide capable of floating in the longitudinal direction of a housing. The present invention also relates to a fishing rod provided with such a fishing line guide.

  The fishing rod includes an elongated rod and a fishing line guide that is attached to the rod and guides the fishing line from the reel to the tip of the rod. There are two types of fishing line guides: a fixed type that is fixed to the outer surface of the frame by bonding or the like, and a floating type that is freely fitted in the frame. A floating type fishing line guide that is freely slidably fitted into the frame may be simply referred to as a floating guide.

  Conventional floating guides are disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2011-010578, 2011-010577, 2010-104264, 2004-187579, 2004-000273, and Japanese Patent Application Laid-Open No. 2004-000273. It is disclosed in Japanese Patent Application Publication No. 2003-284455, Japanese Patent Application Publication No. 2003-274809, and Japanese Patent Application Publication No. 2003-043771.

  As described in these known documents, conventional floating guides generally have a cylindrical mounting portion through which a housing is inserted, a frame extending from the mounting portion, and a through hole formed in the frame. And a hard guide ring to be fitted into the. Prior to use, for example, when the fishing rod is transported, the floating guide is loosely fitted into the housing via its mounting portion. When the fishing rod is used, the loosely-fitted loose guide is moved to the hand side along the rod. Since the housing is formed so that the hand side is thicker, when the floating guide is moved to a predetermined mounting position of the housing, the mounting portion of the floating guide is tightly fitted to the housing. As described above, the floating guide is attached to the casing so as to be freely movable in the longitudinal direction of the casing, and is tightly fitted to a predetermined position of the casing when in use.

  The attachment part and the frame of the floating guide are molded from metal or hard resin. As disclosed in JP-A-60-196134, it has also been proposed to injection-mold a fixed fishing line guide using a fiber reinforced resin.

  In the Japanese Patent Application No. 2015-171206, the inventor has proposed an idle guide in which an attachment portion and a frame are formed of fiber reinforced resin. Since the fiber reinforced resin is generally more elastic than the resin not including the reinforced fiber, when the loose guide made of the fiber reinforced resin is fitted into the housing, a large stress acts on the attachment portion. Such a large stress causes the mounting portion to be broken.

  Accordingly, one of the objects of the present invention is to provide an idle guide in which an attachment portion made of a fiber reinforced resin is not easily broken when attached to a housing.

  One aspect of the present invention relates to a floating fishing line guide provided in the casing so as to be freely movable in the longitudinal direction of the casing. A floating fishing line guide according to an aspect of the present invention includes a cylindrical attachment portion made of a fiber reinforced resin in which a through-hole through which a rod can be inserted is formed, a frame provided on an upper portion of the attachment portion, Is provided. A guide hole for attaching a guide ring for guiding the fishing line is formed in the frame. The attachment portion is provided with a reinforcing portion that protrudes downward from the lower portion thereof.

  According to the inventor's investigation, the floating guide made of fiber reinforced resin is more likely to be broken at the time of mounting to the housing than the floating guide made of resin not containing reinforcing fiber, and this mounting portion. It has been found that the breakage of is likely to occur particularly in the lower part of the mounting portion. The reason why the destruction concentrates in the lower part in the fiber guide made of fiber reinforced resin is considered to be that deformation due to the stress acting from the housing concentrates in the lower part of the mounting portion when the floating guide is fitted into the housing. In other words, the upper part of the mounting part is hardly deformed because it is connected to the frame, and the side part of the floating guide is gripped by hand at the time of mounting, so it is difficult to deform. It is thought to concentrate.

  In the fishing line guide according to one aspect of the present invention, the reinforcing portion is provided at the lower portion of the mounting portion, and the reinforcing portion is not provided at the upper portion, so that the deformation generated at the lower portion of the mounting portion is efficiently suppressed. Can do. That is, if the strength of the mounting portion is simply improved, it is conceivable to increase the thickness of the entire mounting portion, but if the entire mounting portion is increased in thickness, the weight of the fishing line guide will increase. In the fishing line guide according to one aspect of the present invention, since only the lower portion of the attachment portion that is easily broken is reinforced, an increase in weight can be suppressed as compared with the case where the entire attachment portion is thickened.

  Moreover, since the said reinforcement part is formed so that it may protrude below from the lower part of the said attachment part, an unevenness | corrugation is formed in the lower surface of a housing. Thereby, it can suppress that a fishing line sticks to a rod.

  In one embodiment of the present invention, since the entire surface of the reinforcing portion is formed only by a curved surface, the yarn can be prevented from being entangled with the reinforcing portion.

  In one embodiment of the present invention, the reinforcing portion may be formed of the same material (fiber reinforced resin) as the mounting portion, or may be formed of a different material (for example, metal).

  In one embodiment of the present invention, the frame is made of a fiber reinforced resin, a hard resin not containing a reinforced fiber, a metal, or a material suitable for a fishing line guide other than these. The mounting portion and the frame may be integrally molded or may be molded separately. The attachment portion and the frame may be formed of the same material or different materials.

  According to various embodiments of the present invention, it is possible to provide an idle guide in which an attachment portion made of a fiber reinforced resin is hardly broken when attached to a housing.

  Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. The common components are denoted by the same reference numerals across the drawings. It should be noted that the drawings are not necessarily shown to scale for convenience.

  FIG. 1 is an external view of a fishing rod 1 according to an embodiment of the present invention including a fishing line guide 10 according to an embodiment of the present invention. In the illustrated embodiment, the fishing rod 1 is a swing-out type fishing rod having a hand rod 3, a plurality of (three in the example of FIG. 1) medium rods 5, and a tip rod 7. When the fishing rod 1 is not used, the middle rod 5 and the tip rod 7 are stored in the hollow hand rod 3.

  The hand kite 3, the middle kite 5 and the tip kite 7 can be formed using, for example, a prepreg sheet in which a carbon fiber is impregnated with a synthetic resin. In addition, the hand collar 3, the middle collar 5, and the tip collar 7 each have a tapered shape that tapers in the tip direction. The fishing rod 1 is merely an example, and the fishing line guide of the present invention can be used with any fishing rod in which a floating fishing line guide is used.

  A plurality of fishing line guides 10 for guiding the fishing line fed from the reel R to the tip of the fishing rod 1 are provided on the outer peripheral surfaces of the middle rod 5 and the tip rod 7. The fishing line guide 10 is a floating fishing line guide. When the rod bodies 5 and 7 (the middle rod 5 and the tip rod 7) are stored in the hand rod 3, the floating fishing line guide 10 is moved to the end portion on the tip side of the rod body.

  FIG. 2 is a front view of the fishing line guide 10 according to an embodiment, and FIG. 3 is a side view of the fishing line guide 10. 2 and 3, the casings 5 and 7 are omitted. As shown in the figure, the fishing line guide 10 includes a cylindrical attachment portion 14, a frame 16 connected to the upper portion of the attachment portion 14, and an annular shape attached to a through hole (guide hole) formed in the frame 16. A guide ring 12. A through hole 18 extending along the axial direction of the casings 5 and 7 is formed in the mounting portion 14. The casings 5 and 7 are inserted through the through holes 18 of the mounting portion 14.

  The frame 16 is generally formed in a plate shape, and extends from the upper portion of the attachment portion 14 generally upward. In the illustrated example, the frame 16 extends in a direction in which the hand side surface is inclined slightly toward the front (tip side) from the attachment portion 14, while the tip side surface thereof extends from the attachment portion 14 to the housing. It extends in a direction perpendicular to the axial direction. The frame 16 may be configured such that the entire frame 16 extends in a direction perpendicular to the axial direction of the housing. A through hole for attaching the guide ring 12 is formed in the frame 16. The guide ring 12 is fitted and fixed to the inner peripheral surface of the frame 16 that defines the through hole.

  The guide ring 12 is formed of a hard material such as titanium, aluminum, SUS, or ceramics so that the guide ring 12 is not easily worn and the frictional force with respect to the fishing line that slides inward is reduced.

  As described above, the through hole 18 is formed in the attachment portion 14, and the casings 5 and 7 are passed through the through hole 18. The through hole 18 of the attachment portion 14 has a tapered shape that tapers in the tip direction. The through hole 18 is processed to have a predetermined taper by using a tool such as a taper reamer, for example. In this way, the through hole 18 has a tapered shape, whereby the fishing line guide 10 is located at a specific position in the longitudinal direction of the housings 5 and 7, and the inner peripheral surface of the mounting portion 14 is the housing 5 or 7. It is fixed at a position where it comes into contact with the outer peripheral surface. In other words, each of the plurality of fishing line guides 10 according to the embodiment has an inner diameter (penetration) of the mounting portion 14 so as to conform to the outer diameter and the tapered shape of the housings 5 and 7 at a specific position in a predetermined longitudinal direction. The diameter of the hole 18) and the tapered shape of the through hole 18 are set. A plurality of ridges (not shown) formed on the inner peripheral surface defining the through hole 18 of the attachment portion 14 so as to extend along the axial direction of the fishing line guide 10 (longitudinal direction of the rods 5 and 7). You may have. Such protrusions can suppress the rotation of the fishing line guide 10 in the circumferential direction of the housings 5 and 7.

  A reinforcement portion 20 that reinforces the lower portion of the attachment portion 14 is provided below the attachment portion 14. In one embodiment of the present invention, the reinforcing portion 20 is provided so as to protrude downward from the attachment portion 14. When the fishing line guide 10 is fitted into the casings 5 and 7, a portion of the attachment portion 14 connected to the frame 16 (in the illustrated embodiment, a portion above the imaginary line A1 in FIG. 2) 16 so that the deformation of the mounting portion 14 is concentrated at the lower portion (the portion below the imaginary line A1 in FIG. 2 in the illustrated embodiment). The part 20 is provided below the attachment part 14. That is, the reinforcement part 20 is provided in the part below the imaginary line A1 which passes through the center of the through-hole 18 and extends right and left in the attachment part 14. In other words, the reinforcing portion 20 is connected to the mounting portion 14 at a position below the virtual line A <b> 1 on the outer peripheral surface of the mounting portion 14. With the reinforcing portion 20 arranged in this way, the portion of the mounting portion 14 that is easily broken can be efficiently reinforced. In one embodiment of the present invention, the reinforcing portion 20 is configured such that the ratio (T2 / T1) of the thickness T2 at the center to the thickness T1 of the mounting portion 14 is 0.1 to 2.0.

  Further, when the fishing line guide 10 is fitted into the housings 5 and 7, the side portion of the fishing line guide 10 is gripped by hand. For this reason, the lower end part except the side part pressed by hand at the time of attachment among the lower parts of the attachment part 14 is the easiest to deform | transform. Therefore, by providing the reinforcing portion 20 at the lower end portion of the mounting portion 14, the portion of the mounting portion 14 that is easily broken can be reinforced more efficiently. For example, as shown in FIG. 2, the lower end portion of the attachment portion 14 has a virtual line A2 extending downward from the center of the through hole 18 at a predetermined angle (for example, 45 °) in a counterclockwise direction from the virtual line A1. The virtual line extending downward from the center of the through hole 18 at a predetermined angle (for example, 45 °) clockwise from the virtual line A1 is A3, and the virtual line A2 and the virtual line A3 in the front view of the mounting portion 14 are defined as A3. The portion sandwiched between and can be used as the lower end. FIG. 2 shows an example in which the reinforcing portion 20 is provided at the lower end portion of the attachment portion 14.

  In one embodiment of the present invention, as illustrated, the reinforcing portion 20 is formed so that the entire surface thereof is a curved surface. Thereby, it is possible to prevent the fishing line from being entangled with the reinforcing portion 20.

  The dome shape of the reinforcing portion 20 shown in FIG. 2 is merely an example, and the reinforcing portion of the present invention can take various shapes. FIG. 5 shows a fishing line guide 10 ′ according to another embodiment of the present invention provided with a reinforcing portion 120 having a shape different from that of the fishing line guide 10 of FIG. 2. The reinforcing portion 120 has a concave R portion 122 from the center to the periphery. The peripheral edge of the reinforcing portion 120 is thinned by the concave R portion 122. Thereby, stress can be made hard to concentrate near the boundary between the mounting portion 14 and the reinforcing portion 120.

  FIG. 4 shows an example of the fishing line guide 10 attached to the housing 5. As shown in FIG. 4, since the reinforcing portion 20 protrudes downward from the lower portion of the attachment portion 14, unevenness is formed on the lower surface of the housing 5, so that even if the fishing line L is loosened, the fishing line L is Sticking to the bodies 5 and 7 can be suppressed. The same effect can be obtained for the housing 7.

  In one embodiment of the present invention, the attachment portion 14 and the frame 16 are integrally formed of a fiber reinforced resin obtained by impregnating a matrix resin into a large number of reinforcing fibers. For example, the attachment portion 14 and the frame 16 are integrally injection-molded using a matrix resin containing a large number of reinforcing fibers. In one embodiment of the present invention, the reinforcing portion 20 is formed from the same fiber reinforced resin as the mounting portion 14 and the frame 16. In this case, the reinforcing portion 20 is formed integrally with the mounting portion 14 and the frame 16 by injection molding. In another embodiment of the present invention, the reinforcing portion 20 is made of metal. The metal reinforcing portion 20 is bonded to the molded mounting portion 14 by any method for bonding, welding, or bonding other resin and metal.

  In one embodiment of the present invention, the fiber reinforced resin forming the attachment portion 14 and the frame 16 is obtained by impregnating a reinforced fiber such as carbon fiber with a matrix resin such as polyamide resin, polyester resin, polyphenylene ether, polyacetal, or polycarbonate. It is a thing. Each of the reinforcing fibers may be a so-called short fiber having a relatively short fiber length, for example, an average fiber length in the range of 0.5 to 10 mm. By forming the attachment portion 14 and the frame 16 of the fishing line guide 10 using a fiber reinforced resin containing short fibers, the fishing line guide 10 has a fiber reinforced resin containing long fibers whose average fiber length is longer than 10 mm. Bending rigidity is smaller than when molded by. As a result, the fishing line guide 10 according to various embodiments of the present invention can easily ensure followability to the bending of the fishing rod 1. Each of the reinforcing fibers has, for example, a substantially cylindrical shape, an average fiber diameter in the range of 3 to 15 μm, and an average fiber length in the range of 0.5 to 10 mm. Moreover, in one Embodiment, content of the reinforced fiber in fiber reinforced resin exists in the range of 10-60 mass% with respect to matrix resin, for example. The shape, size, content, and the like of the reinforcing fiber disclosed herein are examples, and these characteristics of the reinforcing fiber in the embodiment of the present invention are not limited to those exemplified here.

  In one embodiment, the multiple reinforcing fibers contained in the fiber reinforced resin forming the attachment portion 14 and the frame 16 define at least a portion of the attachment portion 14 and / or the frame 16, for example, the through hole 18 of the attachment portion 14. The longitudinal direction of the casings 5 and 7 is directed at the surface layer portion of the inner peripheral surface and / or the surface layer portion of the inner peripheral surface that defines the through hole 18 of the frame 16. The surface layer portion of the inner peripheral surface that defines the through hole 18 of the attachment portion 14 refers to a region of the attachment portion 14 from the inner peripheral surface to a depth of 2.0 mm, for example. Further, the surface layer portion of the inner peripheral surface that defines the through hole 18 of the frame 16 refers to a region of the frame 16 from the inner peripheral surface to a depth of 2.0 mm, for example. The depth of the surface layer portion described in the present specification is merely an example, and the depth of the surface layer portion in the fishing line guide of the present invention is not limited to that specifically disclosed in the present specification.

  Here, the direction of the reinforcing fibers contained in the matrix resin varies depending on, for example, the position of the gate for injecting the matrix resin mixed with the reinforcing fibers into the injection mold. That is, the direction in which the reinforcing fibers are directed can be changed by changing the direction in which the matrix resin flows during molding. For example, by setting the flow direction of the matrix resin injected into the mold for integrally forming the attachment portion 14 and the frame 16 to a direction corresponding to the longitudinal direction of the casings 5 and 7, the reinforcing fibers included in the matrix resin are Oriented in the longitudinal direction.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the number, position, shape, and the like of the fishing line guide 10 provided in the fishing rod 1 are not limited to the above-described embodiment.
