Problems solved by technology

[0004] As described above, in the portion where the stepped portion is formed, there is a large difference in outer diameter between the bottom of the stepped portion and the top of the stepped portion, so the difference in rigidity between the bottom and the top is too large. Big
In this way, the continuity of rigidity is lost in the stepped portion, and when a fish is hooked and the rod bends, it is difficult to draw a smooth arc, and bending may occur at the stepped portion. that bend
[0005] In addition, since the top and bottom of the step-shaped portion are substantially right-angled corners, when the rod is bent, stress concentration tends to occur at the corners, and there is a problem in terms of strength.

[0063] Such as figure 1 and Figure 4As shown, the fishing rod A is a rod used for fishing Japanese crucian carp. It has a grip part 1A on the tail rod 1 as the rod body. Slubs B are formed at two places on the rod tip side of the grip part 1A, and are bulged through the rod tip side. The bulging part 2 and the butt-side bulging part 3 form a slub B, thereby constituting a fishing rod A.

[0064] In addition, each rod body which comprises the fishing rod A was produced as follows. That is, reinforcing fibers such as carbon fibers are aligned in one direction, and a thermosetting resin such as epoxy resin (or thermoplastic resin) is impregnated into the aligned reinforcing fiber groups to form a prepreg sheet. The prepreg sheet is cut into a predetermined shape and wound on a mandrel, and the above-mentioned multi-layered structure is placed in a furnace in the state wound on the mandrel and sintered. After sintering, the mandrel is The core is removed and the cylindrical ro...

Abstract

The invention discloses a fishing pole; when bitten by a fish, the fishing pole is smoothly bent as an arc , which is capable of buffering stress concentration; a bamboo joint is easy to be made; a plump part of pole head side (2) arranged on the pole head side and a plump part of pole tail side arranged on the pole tail side are arranged on a rear pole (1); an annular concave slot (4), entering to the side of the pole core, is arranged at the approaching position of the end face of the pole head side of the plump part of pole head side (2) and the end face of the pole head side of the plump part of pole tail side (3) approaching to the mutual side edges along the slant edges; the annular concave slot (4) is formed around the circle of the plump part along a slant face (b) slanting to a vertical face (a) that is orthorhombic to a pole axis X; the plump part is made of UV coating.

Description

technical field [0001] The present invention relates to a fishing rod, in which a bamboo-like portion (hereinafter referred to as bamboo) is formed in the middle of the rod body in order to exhibit the performance of a bamboo rod having both toughness and strength. Background technique [0002] In order to form slubs on the rod body, a bulging portion is formed by depositing resin paint, etc. , and form a step-like portion extending along the inclined surface to form a slub (Patent Document 1) [0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-225148 (paragraph number [0024], and figure 1 ) [0004] As described above, in the portion where the stepped portion is formed, there is a large difference in outer diameter between the bottom of the stepped portion and the top of the stepped portion, so the difference in rigidity between the bottom and the top is too large. big. In this way, the continuity of rigidity is lost in the stepped portion, and when a fish is...
