Problems solved by technology

[0005] However, even if such a joint is provided with such a reinforcing piece, it lacks the freedom of operability when fishing.
This is because, in the state of carrying out fishing operation, the load acting on the joint is not simply acting downward, but also acts on the force in the oblique direction, so deformation will occur at this joint, so The rigidity of the rod is reduced, the function of receiving the pull of the fish and accumulating force, and the stiffness of the rod when lifting the rod are reduced.

[0032] Next, the structure used for the draw-out type stream pole A which has multi-section pole bodies, such as a set of 8, is demonstrated.

[0033] Here, the structure of the joint part adopted for the middle pole from the fourth section pole to the penultimate section pole will be mainly described. In the description, the side pulled out is defined as the tip side body 1 , and the side where the tip side body 1 is held is defined as the tail side body 2 . Such as figure 1 As shown in (a), the rod body 1 on the slightly side of the rod is held in the rod body 2 on the tail side so that it can move forward and backward freely, and, as figure 1 As shown in (b), in the state where the pole body 1 on the pole side is pulled out, the outer peripheral surface 1A of the tail end of the pole body 1 on the pole side 1 and the inner peripheral surface 1A of the pole end of the pole body 2 on the tail side are aligned. 2A are fitted into each other in a state of being pressed agains...

Abstract

The present invention provides a fishing rod body capable of suppressing plastic deformation, cracks, and the like at joints, and capable of smoothly bending when a fish bites on a hook, so as to gently withstand pulling of the fish. A reinforcing sheet (5) is disposed on the middle layer at the rod tail end of the rod body (1) on the rod side. The reinforcing sheet (5) is formed by overlapping two sheets of prepreg material, wherein one sheet of prepreg material has a group of reinforcing fibers (c) aligned along a direction forming a first inclination angle (θ1) with the rod axis (X), and the other sheet of prepreg material has a group of reinforcing fibers (c) aligned and arranged symmetrically with the group of reinforcing fibers (c) of the prepreg material relative to the rod axis.

Description

technical field [0001] The present invention relates to a rod body for a fishing rod. The structure of the rod body for a fishing rod is that the outer peripheral surface of the tail end of the rod body on the tip side and the inner peripheral surface of the tip end of the rod body on the tail side are pressed against each other. Fitting each other in the connected state, keeping the rod body on the slightly side of the rod in an elongated state. Background technique [0002] The rod body for a fishing rod is formed by aligning reinforcing fibers such as carbon fibers, impregnating the aligned reinforcing fibers with a thermosetting resin such as epoxy resin to form a prepreg, and winding the formed prepreg on Finally, the tubular core wrapped with the prepreg sheet is fired on the core having a predetermined conical shape to form a fishing rod. [0003] In this way, although the joint portion is formed, it has the effect of preventing the rod body on the tail side from det...
