Description

  The present invention relates to a fishing rod provided with a hollow rod body integrally formed with a rear grip portion.

  In the case where the rod body is provided with a rear grip portion, a tubular rear grip body is often formed from cork or foamed resin, and is mounted on the rear outer peripheral surface of the blank of the rod body in many cases. However, if the rear grip portion is formed separately from the rod body, it is difficult to reduce the weight, and the sensitivity transmitted to the hand from the fishing rod also decreases.

  On the other hand, the present applicant has already proposed a configuration in which the rear portion of a hollow rear grip rod body has a large diameter and a rear grip portion is integrally formed (see Patent Document 1 below). By providing the hollow rear grip rod body in this way, the sensitivity of the fishing rod can be increased, and the weight can be reduced.

  The rear grip rod is joined to the main rod located on the front side. The rear part of the main rod body is inserted inside the front part of the rear grip rod body, and the main rod body and the rear grip rod body are joined and integrated by bonding or the like. However, for example, in a situation where a heavy lure is repeatedly thrown away from the shore or in a fishing where the fishing rod is repeatedly shaken, further improvement in the feeling of holding and swinging the fishing rod is required.

Japanese Patent No. 5721574

  SUMMARY OF THE INVENTION It is an object of the present invention to reduce the feeling of holding and swinging while maintaining the features of light weight and high sensitivity by using a rod body integrally formed with a rear grip portion.

  The fishing rod according to the present invention includes a hollow main rod body, and a hollow rear grip rod body located behind the main rod body and integrally formed with a rear grip portion. A main rod body and a rear grip rod body are joined together by inserting the front part of the rear grip rod body into the inside of the rear part. Note that the pole tip side is the front side, and the rod bottom side is the rear side.

  The front part of the rear grip rod is inserted inside the rear part of the main rod. Therefore, compared to a configuration in which the rear part of the main rod body is inserted inside the front part of the rear grip rod body, the rear part of the main rod body is relatively thick, and the front part of the rear grip rod body is relatively large. It becomes thin. When the rear part of the main rod body becomes thicker, less material such as prepreg is required to obtain the same hardness and strength, and the main rod body becomes relatively lighter. Conversely, when the front part of the rear grip rod body becomes thinner, more material is required to achieve the same hardness and strength, and the rear grip rod body becomes relatively heavy. As a result, the center of gravity of the fishing rod can be located on the rear side as compared with the configuration in which the rear part of the main rod is inserted inside the front part of the rear grip rod. In the configuration with the rear grip rod body in which the rear grip part is integrally formed, the center of gravity of the fishing rod is easily located on the front side, but the front part of the rear grip rod body is inserted inside the rear part of the main rod body. By doing so, it is possible to position the center of gravity of the fishing rod on the rear side while suppressing an increase in weight. As a result, the feeling of holding when holding the fishing rod and the feeling of swinging when casting are reduced. Further, since the rear portion of the main rod body is relatively thick, the butt portion of the fishing rod can be strengthened, and so-called bat power can be increased.

  In particular, it is preferable that a tubular reel sheet is provided, the reel sheet is mounted on the main pole body, the joining portion is shorter than the reel sheet, and the joining portion is preferably located inside the rear portion of the reel sheet. . Since the reel sheet is mounted on the main rod body, vibrations such as fish attack transmitted from the pole tip are transmitted from the main rod body to the reel sheet without passing through the rear grip rod body. Therefore, the transmission loss is reduced, the transmission efficiency is improved, and the vibration is easily transmitted to the hand. In addition, since the joint portion is located inside the rear portion of the reel sheet, the center of gravity is positioned further rearward than in a configuration in which the joint portion is located inside the front portion of the reel sheet. This can further reduce the feeling of holding and swinging.

  Furthermore, the reel sheet has a male thread portion on the outer peripheral surface of the rear portion, a moving hood provided on the reel sheet body, and a male screw portion of the reel sheet body for moving the moving hood back and forth. It is preferable that the joint portion is located inside the male screw portion of the reel seat body. The rear part of the main pole body and the front part of the rear grip rod body are located inside the male thread part of the reel seat body so that the rear part of the main pole body overlaps with the rear part of the main pole body. Supported from the inside by the front. As a result, even if the male thread of the reel seat body is made thinner, the male thread can be prevented from being damaged. In addition, the ease of gripping is improved.

  Also, the thickness of the front part of the rear grip rod is preferably thicker than the thickness of the rear part of the main rod, so that the center of gravity can be located further back, reducing the feeling of holding and swinging. Is done.

  As described above, the front grip of the rear grip rod is inserted inside the rear part of the main rod body and spliced to achieve a feeling of weight and swing while achieving the high sensitivity and light weight by providing the rear grip rod body. The feeling of weight can be reduced.

FIG. 1 is a front view showing an external appearance of a main part of a fishing rod according to an embodiment of the present invention. The longitudinal section of the important section of the fishing rod. FIG. 3 is an enlarged vertical sectional view of a main part of the fishing rod. FIG. 3 is an enlarged vertical sectional view of a main part of the fishing rod.

  Hereinafter, a fishing rod according to an embodiment of the present invention will be described with reference to FIGS. The fishing rod includes a rod body and a reel sheet 5. The rod body includes a main rod body 1 and a hollow rear grip rod body 2 located on the rear side of the main rod body 1. The rear grip rod body 2 is joined and integrated with the main rod body 1. The type of the fishing rod is arbitrary, and may be a joint rod, a swing rod, or the like. For example, in the case of a one-piece rod, the main rod body 1 has a single structure that is continuous up to the tip. In the case of a two-piece rod, that is, a two-piece fishing rod, the fishing rod is composed of a first rod on the tip side and a second rod on the original side, and the reel sheet 5 is provided on the second rod on the original side. In the case of a double spliced fishing rod, the main rod body 1 has a double structure including a first main rod body located on the tip side and a second main rod body located on the base side. The first rod is composed of the first main rod body. The second rod is composed of a second main rod body and a rear grip rod body 2. In the case of a three-joint fishing rod, the fishing rod is composed of a first rod, a second rod, and a third rod in order from the tip side, and the third rod is provided with a reel sheet. In the case of a three-joint fishing rod, the main rod body 1 has a three-piece structure including a first main rod body, a second main rod body, and a third main rod body in this order from the tip side. The first rod is composed of the first main rod, and the second rod is composed of the second main rod. The third rod is composed of a third main rod body and a rear grip rod body 2. In the configuration of two or more joints, the main pole body located closest to the base may be hollow, and the main pole body on the tip side may be solid. For example, a part or the whole of the first main rod body constituting the head rod may be solid.

  The fishing rod of the present embodiment is a three-joint fishing rod. Therefore, the main rod 1 is composed of a first main rod (not shown), a second main rod 30 and a third main rod 31. Hereinafter, the third main pole body 31 is simply referred to as the main pole body 1. The third rod includes a main rod 1 and a rear grip rod 2. By inserting the front part of the rear grip rod body 2 inside the rear part of the main rod body 1, the main rod body 1 and the rear grip rod body 2 are joined together. The joint 3 between the main rod body 1 and the rear grip rod body 2 will be described later. Both the main rod body 1 and the rear grip rod body 2 are hollow. Both the main rod body 1 and the rear grip rod body 2 are formed by winding a prepreg around a mandrel. A tail plug 4 is attached to the bottom of the fishing rod, that is, the rear end of the rear grip rod body 2.

<Rear grip rod 2>
The rear grip rod body 2 has a rear grip portion 21 integrally formed by locally increasing the diameter of a predetermined length region on the rear end side. The rear grip portion 21 is located away from the reel seat 5 by a predetermined distance rearward. The rear grip portion 21 is used by hitting the elbow or forearm of the hand holding the fishing rod, or by gripping with the hand opposite to the hand holding the reel sheet 5 when casting with both hands.

  The rear grip rod body 2 includes two front and rear regions. The rear grip rod body 2 includes a small diameter portion 20 that forms the front part of the rear grip rod body 2 and a rear grip part 21 that forms the rear part of the rear grip rod body 2. The small diameter portion 20 forms a predetermined length region from the front end 2a of the rear grip rod 2, and the length occupies more than half of the entire length of the rear grip rod 2. The small diameter part 20 forms a main part of the rear grip rod body 2. The small diameter portion 20 is longer than the rear grip portion 21. The small diameter portion 20 is a straight portion having a constant inner diameter, but may have a gradient. In the present embodiment, the small diameter portion 20 is a straight portion having a constant inner diameter, and the gradient of the small diameter portion 20 is zero. The front part of the small diameter part 20 is inserted inside the rear part of the main rod body 1. The thickness of the small diameter portion 20 is greater than the thickness of the rear portion of the main rod body 1.

  The rear grip portion 21 is not of a separate configuration but of an integrated configuration integrally formed on the rear grip rod 2. The rear grip portion 21 has a larger diameter than the small diameter portion 20. The rear grip portion 21 has an enlarged diameter portion 22 whose inner diameter increases toward the rear at a steeper gradient than the small diameter portion 20, and a rear grip rod body 2 extending from the rear end of the enlarged diameter portion 22. And a large-diameter portion 23 that constitutes a region up to the end. The enlarged diameter portion 22 has an outer diameter which is increased toward the rear side together with an inner diameter.

  The enlarged diameter portion 22 is divided into two regions before and after. The enlarged diameter portion 22 is partitioned into a front surface portion 22a and a rear surface portion 22b. The front surface 22a is smoothly connected to the rear end of the small diameter portion 20. The front surface 22a has a steeper gradient than the rear surface 22b. The front surface portion 22a is a concave curved surface portion with an outer concave, and its gradient (diameter expansion ratio) is not constant, but becomes larger and steeper toward the rear side. The rear surface portion 22b is a concave curved surface portion that is concave outside, like the front surface portion 22a. However, the rear surface portion 22b may have a tapered shape in which the diameter is linearly increased toward the rear side without being curved, or may be a convexly curved surface portion curved to the outside convexity. The length of the rear surface portion 22 b is longer than the length of the front surface portion 22 a and exceeds half of the entire length of the enlarged diameter portion 22. The rear surface portion 22b occupies most of the length of the rear grip portion 21 and forms a main portion of the rear grip portion 21.

  An annular corner 22c is formed at the boundary between the front surface 22a and the rear surface 22b. The annular corner 22c is formed over the entire circumference, and has a mountain-shaped cross section. That is, since the annular corner 22c is formed at the boundary between the front surface 22a and the rear surface 22b, the front surface 22a and the rear surface 22b are bent back and forth at the annular corner 22c. ing. By forming the annular corner portion 22c in the middle of the enlarged diameter portion 22 as described above, the enlarged diameter portion 22 is partitioned into a front surface portion 22a and a rear surface portion 22b.

  The large-diameter portion 23 is a straight portion having a constant inner diameter, similarly to the small-diameter portion 20, and has a constant outer diameter. The small diameter portion 20 is a front straight portion, and the large diameter portion 23 is a rear straight portion. The length of the large diameter portion 23 is shorter than the length of the large diameter portion 22. The tail plug 4 is mounted on the inner peripheral surface of the large diameter portion 23. The large diameter portion 23 is the largest diameter portion of the rear grip portion 21 and the largest diameter portion of the rear grip rod 2. The large diameter portion 23 has a larger diameter than a nut 13 of the reel sheet 5 described later.

<Reel sheet 5>
A reel is attached to the reel sheet 5. The reel sheet 5 has a tubular shape, also called a pipe sheet, and is externally mounted on a rod body of a fishing rod and fixed to a predetermined position so as not to be movable. That is, the rod body passes through the reel sheet 5, and the reel sheet 5 is fixed to a predetermined position on the outer peripheral surface of the rod body by bonding or the like.

  The reel has a reel leg for attaching to the reel sheet 5. The reel leg is provided with a leg main portion 6 extending in a single leg from a reel body (not shown), and a pair of front and rear mounting legs 7a and 7b extending forward and rearward from the front end of the leg main portion 6 as a whole. It is formed in a T shape.

  The reel sheet 5 is immovably mounted on the rod main body, and has a cylindrical reel sheet main body 11 having a fixed hood portion 10 for fixing one of the mounting legs 7a; And a nut 13 for moving the movable hood 12 in the axial direction (front-back direction) and fixing the movable hood 12 at a desired position. In the present embodiment, the fixed hood portion 10 is located on the front side, and the moving hood 12 and the nut 13 are located on the rear side. That is, the reel seat 5 has a rear lock structure, but the front seat is arranged in reverse. A lock structure may be used. That is, the fixed hood unit 10 may be located on the rear side, and the movable hood 12 and the nut 13 may be located on the front side.

  Although the reel sheet 5 in the present embodiment is suitable for fixing a spinning reel, it may be suitable for fixing a double-axis reel. In a normal use state, the spinning reel faces downward. Therefore, in FIG. 1 and the like, the reel leg support surface 14 for supporting the rear surface of the reel leg is directed downward in accordance with the state of use.

  The reel sheet main body 11 is composed of one member. The material of the reel sheet main body 11 may be a synthetic resin, a metal, or the like, but is preferably a resin molded product formed by injection molding from a hard synthetic resin. A rod insertion hole through which the rod body is inserted is formed in the reel sheet body 11. A reel leg support surface 14 for supporting the rear surface of the reel leg is formed below the reel seat body 11. The back surface of the reel leg is the back surface of the mounting leg portions 7a and 7b of the reel leg. A fixed hood portion 10 is integrally formed at the front end of the reel leg support surface 14. The fixed hood portion 10 is open on the rear side. The front mounting leg 7a is inserted into the fixed hood 10 from the rear.

  A male screw portion 15 is formed on a rear outer peripheral surface of the reel seat body 11. A nut 13 is screwed onto the male screw portion 15 of the reel seat body 11, and the movable hood 12 is located in front of the nut 13. The movable hood 12 is locked to a nut 13 so as to be relatively rotatable. The movable hood 12 has a tubular shape, and a hood portion 12a into which the rear mounting leg portion 7b of the reel leg is inserted is formed at an end opposite to the nut 13. The hood portion 12 a is a portion of the entire circumference at the end of the movable hood 12 partially bulging radially outward, and a reel leg is provided between the hood portion 12 a and the reel seat body 11. The rear mounting leg 7b is inserted from the front. The hood portion 12a of the movable hood 12 is opposed to the fixed hood portion 10 in the front-rear direction, and fixes the reel legs by holding the mounting leg portions 7a, 7b of the reel legs together with the fixed hood portion 10 in the front-rear direction.

  As shown in FIG. 4, a guide groove 16 extending linearly in the front-rear direction is formed in the reel sheet main body 11 so as to partially cut out the male screw portion 15. On the inner peripheral surface of the movable hood 12, a projection 17 that engages with the guide groove 16 is formed. The movable hood 12 slides in the front-rear direction while being guided by the guide grooves 16 of the reel seat body 11. When the nut 13 is rotated, the moving hood 12 moves back and forth with the nut 13 without rotating. By moving the movable hood 12 to the front side and approaching the fixed hood portion 10, the reel can be fixed to the reel seat body 11 while holding the mounting leg portions 7a and 7b of the reel legs back and forth. By moving the movable hood 12 rearward and separating it from the fixed hood section 10, the fixed state of the reel legs is released, and the reel can be removed from the fishing rod.

<Splicing part 3>
The reel sheet 5 is mounted on the main pole body 1. More specifically, a reel sheet main body 11 is mounted on the outer peripheral surface of the rearmost portion of the main pole body 1. The reel sheet body 11 is bonded to the outer peripheral surface of the main pole body 1 directly or via a spacer. In this embodiment, the reel sheet main body 11 is directly bonded to the main pole body 1. A front grip 8 is located on the front side of the reel sheet 5. The front grip 8 is made of a grip material such as foamed EVA or cork. The front grip 8 has a cylindrical shape and is adhered to the outer peripheral surface of the main rod body 1 and the outer peripheral surface of the front part of the reel seat body 11.

  The joint portion 3 between the main rod body 1 and the rear grip rod body 2 is located inside the reel seat 5. The total length of the joining portion 3 is shorter than the total length of the reel sheet 5. Specifically, the joint portion 3 is shorter than the reel sheet body 11. The joining portion 3 is located inside the rear portion of the reel sheet main body 11. More specifically, the joint portion 3 is located inside the male screw portion 15 of the reel seat body 11. The rear end 11a of the reel seat body 11 and the rear end 1a of the main pole body 1 are flush. The main rod 1 does not protrude rearward from the reel seat body 11. The joint portion 3 is longer than the male thread portion 15 of the reel seat body 11. Therefore, the front end 2 a of the rear grip rod body 2 is located on the front side of the male screw portion 15. The joint portion 3 is located behind the center line 6a, which is the center position of the reel leg in the front-rear direction. The front end 2a of the rear grip rod body 2 is located behind the center line 6a of the reel leg. The spliced portion 3 is located behind the center position of the reel leg support surface 14 in the front-rear direction. The front end 2a of the rear grip rod 2 is located rearward of the center position of the reel leg support surface 14 in the front-rear direction.

  As described above, the joint portion 3 is formed by inserting the front part of the rear grip rod body 2 inside the rear part of the main rod body 1. Therefore, as compared with a configuration in which the rear part of the main rod body 1 is inserted inside the front part of the rear grip rod body 2, the rear part of the main rod body 1 is relatively thick, and the main rod body 1 is relatively thick. On the contrary, the front part of the rear grip rod body 2 becomes relatively thin, and the rear grip rod body 2 becomes relatively heavy. As a result, the center of gravity of the fishing rod can be located on the rear side as compared with the configuration in which the rear part of the main rod body 1 is inserted inside the front part of the rear grip rod body 2. In particular, by making the thickness of the small diameter portion 20 of the rear grip rod body 2 greater than the thickness of the rear part of the main rod body 1, the center of gravity can be positioned further rearward.

  In the configuration including the rear grip rod body 2 in which the rear grip portion 21 is integrally formed, the center of gravity of the fishing rod is easily located on the front side. However, by adopting a configuration in which the front part of the rear grip rod body 2 is inserted inside the rear part of the main rod body 1, the center of gravity of the fishing rod can be located on the rear side while suppressing an increase in weight. As a result, the feeling of holding when holding the fishing rod and the feeling of swinging when casting are reduced. Further, since the rear portion of the main rod body 1 is relatively thick, the butt portion of the fishing rod can be strengthened, and so-called bat power can be increased.

  In addition, since the reel sheet 5 is mounted on the main rod 1, vibrations such as fish attack transmitted from the pole tip are transmitted from the main rod 1 to the reel sheet 5 without passing through the rear grip rod 2. Is done. Therefore, as compared with the configuration in which the reel sheet 5 is mounted on the rear grip rod 2, the transmission loss is reduced, the transmission efficiency is improved, and the vibration is easily transmitted to the hand. In addition, since the joint portion 3 is located inside the rear portion of the reel sheet 5, the center of gravity is moved rearward as compared with the configuration in which the joint portion 3 is located inside the front portion of the reel sheet 5. It can be positioned, and the feeling of holding and swinging can be further reduced.

  Further, since the joint portion 3 is located inside the male screw portion 15 of the reel seat body 11, the male screw portion 15 of the reel sheet body 11 can be supported by the joint portion 3 from the inside. Therefore, even if the male screw portion 15 of the reel seat body 11 is thinned, the male screw portion 15 can be prevented from being damaged. The diameter of the moving hood 12 and the nut 13 can be reduced as the diameter of the male screw portion 15 is reduced, so that the reel sheet 5 can be reduced in size and weight, and the ease of gripping is improved.

  In the present embodiment, the fishing rod is provided with the reel sheet 5. However, the fishing rod may not be provided with the reel sheet 5.
