Description

  The present invention relates to a fishing rod provided with an external fishing line guide on a rod having a bias layer.

  When a fish with a strong pull is hung on a fishing rod provided with an external fishing line guide, the rod is swung up and down and left and right as the fish moves. At this time, the rod is twisted via the fishing line guide. However, if the twist is transmitted to the handle portion at hand, the position of the moving fish becomes difficult to understand, so that the rod operation is difficult to perform, and the angler feels uncomfortable. The following Patent Document 1 by the present applicant discloses a fishing rod structure that improves the operability of the fishing rod while reducing the weight. Patent Document 2 discloses a fishing rod in which a moving guide holding portion is formed of a prepreg.

In the region where the bias layer is provided as in Patent Document 1, there is a limit to effectively preventing twisting while reducing the weight only by providing the bias layer substantially uniformly. When a prepreg continuous in the longitudinal direction is wound on the cocoon body layer, the cocoon body layer is tapered, so when the prepreg is wound on the prepreg, the orientation direction of the reinforcing fiber of the prepreg is the cocoon longitudinal direction. Will gradually change along. This makes it difficult to direct the reinforcing fiber direction of the bias layer as designed. Further, the characteristics of the reinforcing fiber and the bias layer cannot be changed depending on the position in the longitudinal direction.
Therefore, a problem to be solved is to provide a fishing rod capable of effectively adjusting the characteristics of the bias layer in the longitudinal direction and effectively preventing torsion.

  In view of the above problems, the first invention is a fishing rod in which a handle portion is provided in the base region of the fiber-reinforced resin rod and a fishing line guide is provided on the outside of the rod. Reinforcing fibers have a bias layer inclined in both directions that are symmetrical with respect to the longitudinal direction of the ridge, and the bias layer includes a plurality of the prepregs divided into a plurality of pieces in the longitudinal direction between adjacent prepregs. There is provided a fishing rod having overlapping portions in which the end regions in the longitudinal direction overlap each other.

In the second invention, in the first invention, one fishing line guide is provided on at least one overlapping portion.
In the third invention, the bias layer of the first or second invention is configured to be provided at least from the front end of the handle portion of the bag to a predetermined position in the front.
In the fourth invention, the bias layer of the first or second invention is configured to be provided from the rear end of the fishing line guide provided at least on the most tip side of the rod to a predetermined rear position.

  In the first invention, since the bias layer prepreg is divided into a plurality in the longitudinal direction of the heel, each prepreg can be wound while the direction of the reinforcing fiber is inclined with high accuracy. Further, at the time of designing, the type (characteristics) of the prepreg reinforcing fiber can be changed in the longitudinal direction as necessary. Furthermore, when the overlapped portion where the inclination-oriented reinforcing fibers are increased partially exists in the longitudinal direction, the overlapped portion is provided over the entire length of the bias layer, that is, the prepregs are extended over the entire length. Compared with the case where they are overlapped, the twisting of the rod through the fishing line guide is transmitted to the handle part, so that the twisting can be effectively prevented by the presence of the overlapping part, and the overlapping part is partially There is no need to increase the bag weight.

In the second invention, since the fishing line guide is provided on the overlapping part, the overlapping part is protected by the fishing line guide, and the torsional torque transmitted to the rod through the fishing line guide is applied by the overlapping part. It can be received and transmitted to the handle portion at the rear position thereof.
In the third aspect of the invention, since the bias layer is provided at least from the front end of the handle portion of the heel to a predetermined position in front, the torsion torque received on the hand side near the handle portion is received and the torsion torque transmitted to the heel is received. Can be prevented from being transmitted to the handle portion.
In the fourth invention, since the bias layer is provided from the rear end of the fishing line guide provided at the most tip side of the rod to a predetermined position in the rear, the torsion torque is received on the tip side that is most likely to be twisted and transmitted to the handle portion. Can be prevented.

FIG. 1 shows a side view of a fishing rod as one embodiment according to the present invention and a manufacturing explanatory diagram thereof. FIG. 2 is an enlarged vertical sectional view of a portion B in FIG. FIG. 3 is a diagram in which a side view of a fishing rod as another embodiment according to the present invention and an explanatory diagram of its manufacturing method are provided.

  Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a side view of a fishing rod as one embodiment according to the present invention and a manufacturing explanatory diagram thereof, and FIG. 2 is an enlarged vertical sectional view of a portion B in FIG. In this example, the rod 20 is a single rod made of fiber reinforced resin using a synthetic resin such as an epoxy resin as a matrix and reinforced with reinforcing fibers such as carbon fibers, but may be a fishing rod having a plurality of seams. . A reel mounting portion 42 for mounting the reel R is provided at a predetermined position of the base portion of the collar 20. In addition, a grip member is attached to a region immediately after that to form a grip portion 44. The reel mounting portion 42 and the grip portion 44 are collectively referred to as a handle portion 40.

  The inner layer 20A is formed on the tapered cored bar 10 by winding a prepreg P1 having a length extending over the entire length of the cored bar and oriented in the circumferential direction of the reinforcing fiber. On the inner layer, the intermediate layer 20B is formed by winding a prepreg P2 having a length extending over the entire length of the cored bar and having a direction in which the reinforcing fibers are oriented in the longitudinal direction of the cored bar. On this intermediate layer, each prepreg P31 has an appropriate length that is less than the total length of the core metal, and is oriented in two inclined directions so that the orientation direction of the reinforcing fibers is symmetric with respect to the longitudinal direction of the core metal. , P32 is wound to form the outer layer 20C as a bias layer. In this case, only the end regions P31E and P32E on the side adjacent to each other in the longitudinal direction of the two prepregs P31 and P32 adjacent to each other in the front-rear direction are polymerized.

  Each of the prepregs P31 and P32 in the above example is a prepreg in which reinforcing fibers symmetric with respect to the longitudinal direction of the core metal are woven and formed or knitted, but the longitudinal direction of the core metal. It may be a prepreg obtained by superimposing prepregs of reinforcing fibers that have different directing directions so as to be symmetrical and are aligned in one direction. Further, the length of the prepreg P32 on the front side is made somewhat longer while including the position of the fishing line guide G1 closest to the handle 40 from the tip of the rod. Further, the length of the prepreg P31 is made somewhat longer while including the position of the fishing line guide G1 closest to the handle portion 40 from the rear end of the rod.

Adjacent end portions of these prepregs are superposed to each other end portion in a narrow range (0.1 cm to 30 cm, more preferably 1 cm to 20 cm) that extends somewhat before and after the fishing line guide G1, respectively. Only the region is polymerized, and this is used as the polymerization part 22. The end of each prepreg on the overlapping portion side is a line orthogonal to the longitudinal direction of the cored bar.
The superposed region in the bias layer is narrower than the non-polymerized portion of the bias layer, and the non-polymerized portions before and after the superposed portion are respectively longer than the superposed portion. In this way, twisting can be effectively prevented without increasing the weight of the bag.

  Generally, the orientation direction of the reinforcing fiber during the winding operation gradually changes along the length direction of the core metal, but as described above, because the prepreg forming the bias layer is divided in the length direction, The amount of change can be reduced. Further, the reinforcing fiber direction of the front side prepreg P31 is set to ± 45 degrees, while that of the original side prepreg P32 is changed to ± 30 degrees, or the elastic modulus and thickness of the reinforcing fibers are changed, that is, the reinforcing By changing the type of fiber, the torsional rigidity on the front side of the fishing rod can be increased or the torsional rigidity on the rear side can be increased.

  If the torsional rigidity of the fishing rod is relatively increased by the front prepreg, the torsional rigidity of the rear prepreg can be effectively prevented by receiving the torsion at the front side of the small diameter fishing rod. Increasing the size is advantageous in that it can easily receive and prevent twisting at the large diameter portion. Further, in this example, the overlapping portion 22 is provided at the position of the fishing line guide G1, and in this example, the fishing line guide G1 is fixed, and the foot portion 24 of the fishing line guide is wound around the rod with the line 26 wound. Since it fixes by rotation, it becomes a reinforcement of a superposition | polymerization part and the peeling prevention of a superposition part can be aimed at.

  Furthermore, since the end portion P31E of the original prepreg P31 that forms the bias layer that is the outermost layer of the cocoon body layer by the prepreg is superposed on the upper side of the front prepreg P32, the two end edges of the overlap portion Of P31e and P32e, the exposed end edge P31e is exposed to the outside, so that when the line is pulled out when the fishing rod is entangled with the fishing line, the fishing line in the tip direction, which is the direction of thread removal. It is difficult to get caught in the overlapping part during the movement of

Unlike the above example, the position of the overlapping portion may not be the position of the fishing line guide G1, but the positions of the other fishing line guides G2 and G3, and not the position of each fishing line guide, for example, the fishing line guide G1 and the handle 40 It may be set at an appropriate position, such as an intermediate position in the area between the tip of the two. Furthermore, the superposition | polymerization part of the prepreg P31 and the prepreg P32 can also make the direction of the prepreg P31 below. In this case, there exists an effect which can prevent delamination.
In addition, when a fishing line guide is provided on the overlapped portion, the end of the bias layer overlap is set to the inner layer side on the side where the amount of deflection before and after the guide is large (so that the end of the overlap does not appear on the surface). There is an effect of preventing delamination.

  FIG. 3 is a diagram in which a side view of a fishing rod as another embodiment according to the present invention and an explanatory diagram of its manufacturing method are provided. Items different from the first embodiment shown in FIG. 1 will be mainly described. The bias layer serving as the outer layer uses prepregs P31, P33, P34, and P35 divided into four in the longitudinal direction, and only the end regions adjacent to each other in the longitudinal direction are polymerized. In this example, the overlapping portions 221, 222, and 223 are provided at the positions of the fixed fishing line guides G1, G2, and G3. Also in the upper and lower sides of the polymerization, the original prepreg is polymerized on the front prepreg. One or two or more overlapping portions may be provided in a region between the fishing line guides or a region between the fishing line guide G1 and the handle portion 40.

  In the above example, the fishing line guide is fixed, but it may be movable. Moreover, although the ridge 20 was hollow, it may be solid. Some of the joints may be solid and others may be hollow. Furthermore, the bias layer may be eliminated from a predetermined position of the fishing rod (rod 20).

  The present invention can be used for a fishing rod provided with an external fishing line guide.
