Description

  The present invention relates to a fishing rod including at least a reel sheet for mounting a reel and a grip for gripping the rod on a rod (blanks) constituting a rod main body, and a method for manufacturing the same.

  In general, a fishing rod used for lure fishing is provided with a reel sheet together with a grip for gripping the fishing rod. This reel sheet is used to detachably attach a reel such as a bait reel or spinning reel. For example, as shown in Patent Documents 1 and 2 below, the reel sheet has an attachment surface on the upper surface of a cylindrical body and is fixed to a moving hood. It has a structure with a hood. Then, with the reel seat inserted into the rod and fixed at a predetermined position, the reel legs are placed on the mounting surface, and both ends of the reel seat are fixed between the moving hood and the fixed hood, thereby fixing the reel to the rod side. It can be securely attached.

  On the other hand, the grip is made of cork, fiber reinforced resin, EVA resin, or the like, and is attached integrally to the rod by being fixed so as to be connected to the reel sheet. In addition, in the case of a jigging rod using a jig as shown in Patent Document 3 below, in addition to a grip integrated with the reel seat, a rear grip is provided with a tail plug at the rod end (base side). It has a structure. In addition, a balancer (weight) is attached to the grip and butt plug to balance the weight before and after the rod centering on the reel seat.

  There are various rod outer diameters and reel seats and grip inner diameters, and depending on the combination, a large gap may be formed between the rod and the rod. For this reason, conventionally, in order to fill the gap, a string or tape is wound as a spacer on the rod side in advance to increase the outer diameter on the rod side, and then an adhesive is applied to the surface for adhesion.

  However, if the thickness, number of windings, spacing, etc. of the kite string or tape are incorrect, this gap is too narrow or conversely too wide to attach firmly, and the work requires a high degree of skill. In addition, when the diameter of the rod changes in a tapered shape, the thickness, the number of windings, and the interval of the kite string or tape must be adjusted depending on the mounting position, which makes the operation more difficult.

  In addition, when the gap between the outer diameter of the rod and the inner diameter of the reel seat or grip is large, such as a jigging rod, the gap cannot be filled with thread and tape alone, so spacers such as carbon arbor and hybrid arbor Must be used. In this case, the arbor is first fixed on the rod with a large amount of adhesive, and after the adhesive is completely dried, a reel sheet or grip is inserted on the arbor, and further, these are fixed with a large amount of adhesive. Therefore, the work becomes more and more difficult.

  In addition, when a balancer made of stainless steel or brass is installed on the rod end or butt plug side, the balance between the front and rear of the rod is balanced when the rod is held horizontally, but when the tip of the rod is raised slightly, the balancer Depending on how you hold it, it may become unstable.

  Therefore, the present invention has been devised to solve these problems, and its main purpose is to perform assembly work efficiently without performing work for filling the gap between the rod and the reel sheet. It is an object of the present invention to provide a novel fishing rod and a method for manufacturing the same. In addition, another object of the present invention is to provide a novel fishing rod capable of ensuring an optimum weight balance without incorporating a balancer made of stainless steel or brass, and a method for manufacturing the same.

  In order to achieve the above object, a first invention is a fishing rod having at least a reel seat and a grip on a rod, wherein the reel seat and the grip have a through hole into which the rod is inserted, and the penetration A fishing rod characterized in that a hard foamed resin layer is provided between a hole and the rod.

  According to such a configuration, the reel sheet and the grip can be easily and surely attached to the rod only by press-fitting the rod into the hard foamed resin layer provided between the through hole and the rod. Accordingly, it is not necessary to use a conventional string or tape for filling the gap, so that an efficient assembling operation can be performed.

  A second invention is a fishing rod according to the first invention, wherein the diameter of the rod changes in a tapered shape. According to such a configuration, a change in the diameter of the rod due to the taper can be reliably allowed by the deformation of the hard foamed resin layer due to its elastic force.

The fishing rod is characterized in that the foaming rate of the hard foamed resin layer filled in the front grip and the rear grip is adjusted to adjust the position of the center of gravity. According to such a configuration, it is possible to arbitrarily adjust the position of the center of gravity without using the balancer provided on the bottom plug only by appropriately changing the foaming ratio of the hard foam resin layers of the front grip and the rear grip.

  According to a fourth invention, in the third invention, the weights thereof are adjusted by the material or structure of the front grip and the rear grip to adjust the position of the center of gravity on the rod end side from the reel seat. A fishing rod. According to such a configuration, the adjustment of the center of gravity, which cannot be achieved only by the foaming rate of the hard foamed resin layers of the front grip and the rear grip, can be reliably achieved by the material or structure of the front grip and the rear grip.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an embodiment of a fishing rod 100 according to the present invention, which is a type of fishing rod generally called a bait rod. As shown in the figure, the fishing rod 100 has a structure in which a reel sheet 20 and a grip 30 are integrally attached on a rod 10 constituting a rod body. The rod 10 may be referred to as blanks.

  The rod 10 is a hollow pipe body made of reinforced fiber plastic (FRP) such as glass fiber or carbon fiber, and has a diameter of about 8 to 22 mm on the straight or rod top side. It has a tapered shape with a diameter decreasing toward. The rod 10 may be a two-piece or three-piece structure that can be divided along the way, in addition to the one from the butt portion on the reel sheet 20 side to the tip portion at the tip of the heel. Although not shown, an annular guide (not shown) for guiding the line is provided on the rod 10 at a predetermined interval along the longitudinal direction.

  The reel sheet 20 is used to detachably attach a reel 50 such as a bait reel or spinning reel, and has a cylindrical body having a through hole H through which the rod 10 is inserted. The reel sheet 20 shown in the figure is for attaching a bait reel. A reel mounting surface 22 is provided on the side surface (upper side in the figure) of the main body 21 and on the opposite side (lower side in the figure). Is provided with a trigger handle 23 for placing a finger. Further, a fixed hood 24 is provided at one end of the reel mounting surface 22, and an annular moving hood 25 that expands in a taper shape is fitted to the other end so as to be movable toward and away from each other. In the case of the reel sheet 20 for spinning reel, the trigger foot 23 is not provided because the reel foot (leg part) is used with a finger.

  As shown in FIG. 2, the movable hood 25 is integrated with a nut member 26 in which a female screw is engraved on the inner periphery, and the nut member 26 is formed on a male screw engraved on the end of the reel seat 20. The moving hood 25 can be moved closer to and away from the fixed hood 24 by screwing. As shown in FIG. 1, the reel 50 can be fixed to the main body 21 by sandwiching both ends of an inverted T-shaped reel foot (leg part) 51 by the fixed hood 24 and the movable hood 25.

  Note that the main body 21 and each member of the reel sheet 20 are formed of reinforced plastic, metal, or other robust material, like the rod 10. Further, the inner diameter of the through hole H formed in the main body 21 of the reel sheet 20 is various. For example, 16 mm, 17 mm, 18 mm for fresh water, 20 mm, 22 mm, etc. are used for sea. .

  As shown in FIG. 1, the grip 30 includes a front grip 31 provided so as to be connected to the reel seat 20, and a rear provided apart from the front grip 31 and a bottom plug 40 on the base (rod end) side of the rod 10. And a grip 32. The front grip 31 and the rear grip 32 are for gripping the rod 10 with the right hand or the left hand, respectively, and as shown in FIG. It is a cylindrical body in which is formed.

  The main body 33 constituting the outer shell of the front grip 31 and the rear grip 32 is a single layer, or two or three layers of reinforced fiber plastic (FRP) such as glass fiber or carbon fiber. It has a high-strength monocoque structure that is strong enough to handle the angler's grip.

  3 and 4 are enlarged sectional views of the reel sheet 20 and the front grip 31, respectively. As shown in the drawing, a gap (gap) between the reel sheet 20 and the through hole H of the front grip 31 and the rod 10 is filled with a layer W made of a hard foamed resin such as hard urethane foam. The rear grip 32 has the same structure as the front grip 31, and the bottom plug 40 also has a recess into which the rod end is fitted instead of the through-hole H, and the entire shape is round and round. Other than that, the front grip 31 has substantially the same structure.

  Next, an example of the manufacturing method of the fishing rod 100 according to the present invention having such a configuration will be described with reference to FIGS. First, as shown in FIG. 5, a hard foamed resin WF such as foamed urethane foam is filled into the inside of the reel sheet 20 before attachment from the other end in a state where the end of the through hole H is closed.

  The filling method of the hard foamed resin WF is not particularly limited. For example, as shown in the drawing, a stock solution composed of polyol (liquid A) and polyisocyanate (liquid B) is weighed into a beaker, etc. In the sheet 20, the end portion of the through hole H is closed, and a liquid is injected into the inside from the other end and foamed and filled (hand mixing method), or a hard foam resin spray as shown in FIG. A method of filling the hard foamed resin WF, which is discharged in a mousse form from the tip of the nozzle without any gap, by inserting the nozzle into the through-hole H using the dedicated discharge gun K with the can B attached thereto. (Spray method) is suitable.

  Next, when the hard foamed resin WF is filled in the through-hole H in this way, it is left as it is until the filled hard foamed resin WF is completely solidified. In the case of a foamed urethane foam that is usually marketed, it solidifies in about 30 minutes to several hours, but it is desirable to leave it for at least half a day in order to solidify completely.

  When the hard foam resin WF filled in the through hole H is completely solidified, the reel sheet 20 is fixed to a punching machine (not shown) as shown in FIG. An insertion hole H2 is drilled in the axial center portion of the hard foamed resin WF so as to be coaxial with the through hole H. At this time, the size of the drill P is selected so that the diameter of the insertion hole H2 to be drilled is substantially the same as the outer diameter of the rod 10 or slightly smaller than that. For example, if the outer diameter of the rod 10 is 12 mm, a drill P having a drilling diameter of about 11 to 12 mm is used. Similarly, the front grip 31 and the rear grip 32 are filled with the hard foamed resin WF and cured, and then the shaft center portion is drilled with the drill P.

  Next, when the insertion hole H2 is drilled in the portion of the hard foamed resin WF in this way, the rod 10 is press-fitted into the insertion hole H2 from its tip as shown in FIG. At this time, the diameter of the insertion hole H2 is equal to or less than the outer diameter of the rod 10 as described above, and an adhesive is applied to one or both of them, and the sizes do not match. That is, the outer diameter of the rod 10 is slightly larger.

  However, since the hard foamed resin WF has a certain degree of elasticity even after it is completely solidified, if the rod 10 is pushed in with an appropriate force, the insertion is made as shown in FIG. Since the hole H2 is expanded by the pressure input, it can be inserted without difficulty without damaging the hard foamed resin layer W.

  If the reel sheet 20 is pushed to a predetermined position on the rod 10 in this way, the front grip 31 previously punched in the same manner as shown in FIG. Connect to the sheet 20. Thereafter, the rear grip 32 and the bottom plug 40 are attached to the base side of the rod 10 in the same manner, whereby the attachment of each component to the rod 10 is completed.

Thus, in the fishing rod 100 of the present invention, the hard foam resin WF is filled in advance in the reel sheet 20 and the grip 30, and after hardening this, the insertion hole H2 having the same diameter as or less than that of the rod 10 is formed in that portion. Since the rod 10 is press-fitted and attached to the insertion hole H2, the attachment work of each member can be performed easily and efficiently as compared with the conventional method using the kite string or tape. Further, since the hard foamed resin WF has self-adhesiveness, it can be firmly fixed only by being in close contact with the surface of metal or plastic without using an adhesive. For this reason, since the operation | work of the application | coating of the adhesive agent to the inside of the reel sheet | seat 20, the front grip 31 manufactured by the hollow structure, and the rear grip 32, the wiping work, etc. can be omitted, the outstanding workability | operativity can be exhibited. Since the surface of the hard foamed resin layer W has a porous cell shape, an adhesive such as an epoxy resin is attached to the cell when the reel sheet 20, the front grip 31 and the rear grip 32 are attached to the rod 10. Because it hardens as it gets inside and bites in, it can be firmly fixed.

  Further, even when the gap between the outer diameter of the rod 10 and the inner diameter of the reel seat 20 is large like a jigging rod, it is possible to fill the gap firmly without using a spacer such as carbon arbor or hybrid arbor. . Moreover, since the material to be used is only a commercially available material such as urethane foam, and a general-purpose punch can be used as it is, the manufacturing cost is also low. Moreover, since the foamed urethane foam constituting the hard foamed resin WF has a closed cell structure, even if this portion gets wet or drops into the water, there is no possibility that moisture or water vapor enters the cell.

  Furthermore, according to the present invention, the conventional balancer attached to the bottom plug 40 by appropriately changing the foaming rate of the hard foamed resin WF to be used, that is, its weight, or by changing the configuration of the main body 33 of the grip 30. Can be omitted, or the overall weight can be reduced. That is, as shown in FIG. 11A, the expansion ratio of the hard foam resin WF of the front grip 31 is increased (weight reduction), and the expansion ratio of the rigid foam resin WF of the rear grip 32 is increased (weight reduction). As a result, the overall weight can be reduced. Also, as shown in FIG. 5B, the foam ratio of the hard foam resin WF of the front grip 31 is increased (weight reduction) and the foam ratio of the hard foam resin WF of the rear grip 32 is decreased (weight increase). Thus, the balance of the rear center of gravity can be adjusted. Furthermore, if the expansion ratio of the hard foam resin WF of the front grip 31 is reduced (weighted) and the expansion ratio of the rigid foam resin WF of the rear grip 32 is made normal as shown in FIG. Therefore, it is possible to perform arbitrary balance adjustment by adjusting the position of the center of gravity without using a conventional balancer.

  In addition, when there is a limit only by the adjustment based on the expansion ratio of the hard foam resin WF, the balance adjustment can be performed more effectively by changing the structure and material of the main body 33 of the front grip 31 and the rear grip 32. It can be carried out. For example, as shown in FIG. 11, the main body 33 has a one-layer, two-layer, or three-layer structure, and these are combined with carbon fibers C or glass fibers G, whereby the weight and strength can be freely adjusted. As shown in the figure, if the main body 33 has a one-layer or two-layer structure, it is possible to reduce the weight of the main body 33 by using only the lightweight carbon fibers C. For example, if it is composed of a combination of carbon fiber C and glass fiber G heavier than this or only glass fiber G, the portion can be adjusted to a normal weight. Furthermore, if the main body 33 has a three-layer structure, if the main body 33 is composed of a combination of the carbon fiber C1 layer and the glass fiber G2 layer, or all the glass fiber G2 layer, the portion can be weighted.

  The weight relationship of these combinations is as follows: C1 layer (1) <C2 layer (2) <C1 layer + G1 layer (3) <G2 layer (4) <C1 layer + G2 layer (5) <G3 layer (6 For example, as shown in FIG. 12A, if both the front grip 31 and the rear grip 32 are configured as (1), the overall weight can be reduced. If the front grip 31 has the configuration (1) and the rear grip 32 has the configuration (4), the balance of the rear center of gravity can be adjusted. Furthermore, if the front grip 31 has the configuration (6) and the rear grip 32 has the configuration (2) as shown in FIG. 5C, the balance of the front center of gravity can be adjusted. Thus, the desired balance adjustment can be easily performed by appropriately changing and combining the expansion ratio of the hard foamed resin WF and the structures and materials of the front grip 31 and the rear grip 32.

  Further, since the hard foamed resin layer W has an appropriate elasticity, even if the diameter D1 on the rod end side is larger than the diameter D2 on the rod top side as shown in FIG. By appropriately deforming the resin layer W, it is possible to reliably absorb the change in the diameter of the rod 10 due to the taper. In the drawing, it is easy to understand that the rod 10 is tapered, but in reality, the change in the diameter of the rod 10 is very small at a distance (about 5 to 10 cm) of the length of the reel sheet 20. .

  Further, such a structure and manufacturing method using the hard foamed resin WF may be adopted only for one of the reel sheet 20 or the grip 30 and the other may be attached to the rod 10 by a conventional method. The present invention can be applied to a fly rod and the like in addition to a spinning rod and bait rod, and the grip 30 is not clearly divided into a front grip 31 and a rear grip 32 (long grip). It can also be applied to those. In addition, the balance adjustment of the long grip can be made by changing the expansion ratio of the hard foam resin injected into the rod top side and rod end side, the material and material of the long grip body, and the balance adjustment such as the overall weight reduction and the rear center of gravity and front center of gravity. It becomes possible.
