  By the way, a fishing rod having a structure in which a plurality of rods as described above are joined, when a sudden load is generated on the small-diameter rod side, stress is concentrated on the rod receiving portion of the large-diameter rod, so that damage or the like occurs. May occur.

  The present invention has been made based on the above-described problems, and an object thereof is to provide a fishing rod having a joint structure that is not easily damaged even when a sudden load is applied.

In order to achieve the above-described object, the fishing rod according to the present invention includes a holding member that holds a small-diameter rod and is joined to a tubular large-diameter rod, and the holding member is an element of the small-diameter rod. A holding portion that holds the side, and an insertion portion that is inserted into and fixed to the distal end opening of the large-diameter ridge, and the insertion portion has the holding member inserted and fixed into the distal-end opening of the large-diameter ridge time, have a shape which gap is formed between the distal end side of the inner surface of the large径竿rod, said holding member comprises a large-diameter portion becomes larger than the inner diameter of the distal end opening of the large径竿rod, the insertion portion is characterized that you have gradually reduced in diameter toward the insertion direction from the large-diameter portion.

  According to the fishing rod having the above-described configuration, even if a large load acts on the small-diameter rod and bends greatly, the holding member that holds it has an insertion portion that creates a gap with the inner surface of the large-diameter rod. As a result, large deflection of small-diameter ridges is allowed, it is possible to relieve stress-concentrated areas, and it is possible to suppress the occurrence of breakage at the heel-receiving portion of large-diameter ridges. Become.

  According to the present invention, it is possible to obtain a fishing rod having a joint structure that is not easily damaged even when a sudden load is applied.

  1 to 4 are diagrams showing an embodiment of a fishing rod according to the present invention, FIG. 1 is a diagram showing an overall configuration, FIG. 2 is a diagram for explaining a joint structure, and FIG. 3 is a diagram showing a small-diameter rod. FIG. 4 is a view showing a state in which a member is held by a member and joined to a large-diameter ridge, and FIG.

  The fishing rod 1 of the present embodiment has a structure suitable for fishing small fish such as a smelt, for example, and has a head rod (tubular large-diameter rod) 3 and a tip rod (small-diameter rod) 5. It is comprised as what is called a two-piece fishing rod which joins. In this case, the spear 5 is joined by inserting the holding member 10 into the front end opening 3 a of the base rod 3 while being held by the holding member 10.

  The said main fence 3 is comprised by the tubular body, for example, wound the so-called prepreg sheet which impregnated the reinforced fiber (mainly carbon fiber, glass fiber, etc.) with the synthetic resin around the core, and passed through the heating process. Thereafter, it is formed in a predetermined size according to a conventional method such as decentering. On the outer periphery of the base end side of the main rod 3 formed in this way, a reel mounting portion (detailed configuration is not shown) for mounting the reel R around which the fishing line is wound is provided.

  The tip rod 5 is made of a material such as a synthetic resin or a fiber reinforced resin into a rectangular flat plate shape (sheet shape), and a fishing line for guiding a fishing line fed out from the reel R on the outer surface thereof. Guides 7 are attached at predetermined intervals.

  In such a flat-shaped pointed tip, it becomes possible to sensitively detect the subtle clams of small fish such as smelt, and by holding the holding member 10 configured as follows, breakage, etc. It becomes possible to make it easy to visually recognize the hit.

  The holding member 10 that holds the tip ridge 5 is made of a soft body that is elastically deformed, such as rubber. In addition, it may be made of a foam material such as EVA or urethane, a hard resin such as ABS, nylon, or POM, or a metal.

  The holding member 10 includes a holding portion 11 that holds the original side of the tip rod 5 and an insertion portion 15 that is inserted into and fixed to the inside from the front end opening 3a of the head rod 3, and is substantially circular as a whole. It is configured in a columnar shape.

  In this embodiment, since the said tip hook 5 is comprised by the flat member, the said holding part 11 follows a horizontal direction so that the former side of the tip hook 5 may be inserted and hold | maintained. It is comprised by the insertion hole 12 which comprises the bottom part 12a in the shape of a flat. That is, the holding portion 11 having a bottomed structure in this way prevents the tip rod 5 from being accidentally inserted too much (functions as a stopper). Furthermore, during actual fishing, It is possible to make it difficult for water to enter the water.

  It is preferable that the above-mentioned holding part 11 is gradually enlarged in diameter toward the opening side so that a gap is formed between the outer surface of the tip heel 5 when holding the tip heel 5 (such an expansion). The diameter region is indicated by reference numeral 12c). That is, as shown in FIG. 3, the height of the insertion hole 12 is gradually increased toward the opening side in the configuration in which the plate-shaped tip is inserted and held in the insertion hole 12 as in the present embodiment. By forming in this way, it is possible to prevent the tip collar 5 and the inner surface of the insertion hole 12 from coming into contact with each other, thereby making it possible to suppress breakage or damage due to stress concentration and the tip collar 5 It becomes easy to insert.

  In particular, when the holding member 10 is made of a hard resin or metal, it is possible to effectively suppress breakage or damage due to stress concentration by expanding the diameter of the tip end side of the insertion hole 12 as described above. It becomes possible.

  The insertion portion 15 of the holding member 10 has a gap between the holding member 10 and the inner surface 3b on the front end side of the main rod 3 when the holding member 10 is inserted and fixed in the front end opening 3a of the main rod 3. It has become a shape.

  Specifically, the holding member 10 has a large-diameter portion 10A having a larger diameter than the inner diameter D of the front end opening 3a of the main shaft 3 (the position having the largest diameter as the holding member, and the outer diameter of the large-diameter portion is In the case of D1, D1> D), and the insertion portion 15 has a shape that gradually decreases in diameter from the large diameter portion 10A toward the insertion direction. That is, with such a shape of the insertion portion 15, when the holding member 10 is inserted into the tip opening 3 a of the main shaft 3, it can be locked at any portion of the insertion portion 15 that gradually decreases in diameter (that Such a locking portion is indicated by reference numeral 15A), and a gap is formed between the locking portion and the inner surface 3b on the distal end side of the main shaft 3 in the region on the insertion side.

  Note that the locking portion 15A comes into line contact with the front end opening 3a of the main shaft 3, but some notches and recesses are formed in the vicinity of the locking portion 15A of the holding member 10 ( (It is formed above the central axis) and may not be in line contact. Further, as shown in the figure, the front side of the large-diameter portion 10A may be gradually reduced in diameter as it moves to the tip, or may be exposed in a straight shape.

  In the present embodiment, slits 14 are formed in the holding member 10 on both sides in the horizontal direction of the insertion hole 12 along the axial length direction. The slit 14 is formed to terminate in front of the bottom portion 12a.

  According to the above configuration, the insertion portion 15 has a shape that creates a gap with the inner surface 3b on the distal end side of the base rod 3, so that, as shown in FIG. 3 and FIG. Even if a sudden load is applied to the heel 5 and it bends greatly, the insertion portion side of the holding member 10 can be displaced, and it is possible to prevent breakage or damage due to stress concentration at the tip of the holding portion of the tip heel 5. It becomes possible.

  Moreover, as shown in FIG. 4, since the insertion part 15 of the holding member 10 can also be displaced until it contacts the inner surface 3b of the base rod 3 together with the displacement of the tip collar 5, A displacement amount larger than the displacement amount of the tip portion due to the inherent rigidity is obtained, and it is possible to clearly recognize the fish hit. Furthermore, when the fish eats the food, the resistance due to the original rigidity of the tip of the tip can be softened until the insertion portion 15 of the holding member 10 contacts the inner surface 3b of the base 3. , Fish will not release food due to a sense of incongruity and can be eaten naturally.

  In the configuration described above, the insertion portion 15 has a shape that gradually decreases in diameter from the large diameter portion 10 </ b> A toward the insertion direction, so the holding member 10 is inserted and pushed into the front end opening 3 a of the main shaft 3. As a result, the area of the large-diameter portion 10A is reduced in diameter, and as a result, the outer surface of the tip collar 5 held in the insertion hole 12 is pressed by the inner surface of the insertion hole 12 to hold the tip collar 5 The state becomes stable.

  In particular, in this embodiment, since the slits 14 are formed on both sides in the horizontal direction of the insertion hole 12, when the holding member 10 is inserted into the tip opening 3a of the main shaft 3, the region of the large diameter portion 10A is vertically It becomes easy to reduce the diameter in the direction, and the inner surface of the holding member 10 (the inner surface of the fitting hole 12) and the outer surface of the tip hook 5 are pressed against each other, and the holding state of the tip hook can be reliably maintained.

  Further, in the above-described configuration, when the holding member 10 is inserted and fixed in the front end opening 3a of the main shaft 3, it is preferable that the insertion portion 15 is exposed at a rear side of 5 mm or more from the large diameter portion 10A ( L is 5 mm or more). By securing the exposed area of the insertion portion 15 in this manner, the exposed portion can be easily picked with a finger, and the holding member 10 can be easily removed from the main rod 3. It should be noted that it is desirable that the entire protrusion of the holding member 10 is about 10 mm.

  Further, in the above-described configuration, the insertion portion 15 has a gap over 360 ° with respect to the inner surface 3b of the main rod 3 by gradually reducing the diameter in the insertion direction. The shape may be such that there is a gap on the upper side (the direction in which the insertion portion 15 can be displaced even if the tip 5 is bent downward due to the fish being caught). Thus, if there is a gap at least on the upper side, the rear end side of the holding member 10 can be flexibly displaced upward.

  Furthermore, when the holding member 10 is formed of an elastic member, it is preferable that the thickness of the insertion portion 15 is formed such that the rear end side (insertion side) is thinner than the large diameter portion 10A side. By comprising in this way, the rear end side of the tip 5 which fitted in the insertion hole 12 becomes easy to displace, and while being able to suppress a crease | fold, damage, etc., it becomes possible to visually recognize a hit clearly.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the shape of above-described embodiment, It can change variously. For example, although the fishing rod described above has a structure suitable for small fish such as smelt, it is not limited to such applications.

  For example, the number of ridges and the cross-sectional shape thereof can be appropriately modified. In other words, the shape of the tip ridge (small diameter ridge) can be appropriately modified, such as a solid shape, a hollow shape, a circular cross section, or an elliptical cross section. Further, according to such a shape, the shape of the holding portion 11 that holds the small-diameter flange of the holding member 10 can be appropriately modified. Further, the shape, location, number, etc. of the slits 14 for facilitating deformation can be appropriately modified.
