The present invention relates to a rod for fishing rods formed of prepreg as a material.

The rod for mandrel is a mandrel having a predetermined taper shape of a prepreg sheet formed by mixing reinforcing fibers such as carbon fibers and impregnating the mixed reinforcing fibers with a thermosetting resin such as epoxy. It is wound up and wound, and the normal thing wound up is baked and formed.

And the pole end of the small diameter pole is pressed against the pole end side of the pole of the large diameter pole, and the structure of the small pole pole is prevented from falling out. Since a load concentrates, the structure which improves intensity | strength by winding the auxiliary pattern which cut | disconnected the prepreg shortly to this part was employ | adopted.

Here, the auxiliary pattern is a cut of a prepreg formed by mixing a reinforcing fiber in the pole axial direction and impregnated with a thermosetting resin in a predetermined shape, and refers to a short length along the pole axial direction. In contrast, the prepreg is cut into a predetermined shape, and a long length along the pole axis direction is called a main pattern.

In addition, a pole is provided, wherein a prepreg having the same length along the same axial direction is overlapped to form an inner and outer layer, and the first layer having a reinforcing fiber group in which the inner layer is mixed along a first inclination angle with respect to the pole axis. The outer layer is constituted by overlapping a prepreg with a second prepreg having a reinforcing fiber group of the first prepreg and a reinforcing fiber group mixed and arranged in a state symmetrical with respect to the long axis. A third prepreg having a group of reinforcing fibers mixed and disposed along a second inclination angle that is equal to the first inclination angle with respect to the reinforcing fiber group and the reinforcing fiber group of the third prepreg and in a symmetrical manner with respect to the long axis; The 4th prepreg which has the reinforced reinforcement fiber group is piled up, and is comprised (refer patent document 1).

<Patent Document 1> Japanese Patent Publication No. 3553365 (Paragraph No. [0013] and Fig. 1)

In the above auxiliary pattern, since the reinforcing fibers are only mixed in the axial direction of the poles, when the poles are warped, they can exert a force against the tensile force acting in the axial direction of the poles, thereby preventing breakage by bending. . However, the shear force acting in the direction inclined with respect to the pole axis was not sufficiently countered, and there was a point that the strength was insufficient.

As a result, in the case of being formed by the auxiliary pattern having the reinforcing fibers mixed in the axial direction, there is a problem such as deformation or cracking in the seam portion such as the pole end portion of the small diameter rod or the like.

On the other hand, in the case where the mixing direction of the reinforcing fibers is formed by overlapping the prepregs inclined with respect to the long axis, the mixing direction of the reinforcing fibers is set in the same direction with respect to the long axis in both the inner and outer layers. Although the strength is exerted on the shear force from the direction orthogonal to the mixing direction, the force against the shear force from the other direction is weak.

An object of the present invention is to provide a rod of a fishing rod which can flexibly withstand the pulling of the fish while producing a smooth warpage when the fish is caught while suppressing deformation and cracks at the joint.

〔Configuration〕

A characteristic configuration of the invention according to claim 1 is a rod for fishing rods formed by a prepreg having a group of reinforcing fibers arranged in a mixed state, wherein the rod is provided with an inner layer and an outer layer, and the inner layer is poled. A first prepreg having a group of reinforcing fibers mixed and disposed along a first inclination angle with respect to an axis, and a group of reinforcing fibers mixed and arranged in a symmetrical manner with respect to the reinforcing fiber group of the first prepreg and the long axis; A third prepreg having the reinforcing fiber group mixed and arranged along the second inclination angle which is an inclination angle smaller than the first inclination angle with respect to the long axis, and the third prepreg overlapping with the second prepreg; Overlaying the fourth prepreg having the reinforcing fiber group of the leg and the reinforcing fiber group arranged in a symmetrical manner with respect to the long axis And the point that Sanctuary configuration, the functions and effects are as follows.

〔Action〕

In other words, after the first prepreg and the second prepreg are configured to overlap each other, the third prepreg and the fourth prepreg are overlapped, whereby the reinforcing fibers are arranged in a cross state. As a result, the reinforcing fiber exerts a counter force in the circumferential direction, thereby exhibiting a counter force against bending failure and increasing the counter force against the shear force to avoid cracking and the like.

In addition, since the direction of the reinforcing fibers in the inner and outer layers is not inclined in the axial direction or the circumferential direction but inclines with respect to both directions, the counter force against bending is gentler than when the reinforcing fibers are arranged in the axial direction. Even if the winding is overlapped, the rigidity becomes too large and the flexibility is not lost.

Therefore, it can bend easily and can flexibly withstand the pull of a fish.

〔effect〕

As a result, it is possible to suppress deformation, cracking, and the like in bending fracture and seam, and to provide a rod that can bend easily and flexibly.

A characteristic configuration of the invention according to claim 2 is a rod for fishing rods formed by a prepreg having a group of reinforcing fibers arranged in a mixed state, wherein the rod includes an inner layer, an intermediate layer, and an outer layer, and the inner layer. And a first prepreg having a reinforcing fiber group mixed and disposed along a first inclination angle with respect to the long axis, and a reinforcing fiber group arranged in a symmetrical manner with respect to the reinforcing fiber group of the first prepreg and the long axis. A third prepreg having a reinforcing fiber group mixed and arranged along the second inclination angle which is an inclination angle smaller than the first inclination angle with respect to the long axis, and the second prepreg having a second superpreg; A fourth prepre having a group of reinforcing fibers of the three prepregs and a group of reinforcing fibers mixed and disposed symmetrically with respect to the long axis; And a fifth prepreg having a group of reinforcing fibers mixed and arranged along a third inclination angle, the inclination angle smaller than a first inclination angle with respect to a long axis, and the inclination angle greater than the second inclination angle with respect to a long axis. The reinforcing fiber group of the prepreg and the 6th prepreg having the reinforcing fiber group mixed and arranged in a state symmetrical with respect to the said long axis are superimposed, and the effect is as follows.

[Action effect]

That is, although the prepreg crossing the reinforcing fibers is used as the intermediate layer, since the inclination angle with respect to the long axis is set to the inclination angle between the inner layer and the outer layer, the force from the inner layer to the outer layer is changed. Propagation can be performed smoothly, and stress does not concentrate locally. In addition, the inclination angle is as small as that of the outer layer, and the arrangement structure of the reinforcing fibers corresponding to the magnitude of the tensile force acting on each layer when warping is applied. In addition, since all three layers are inclined arrangement | positioning which does not deviate to any of an axial direction or a circumferential direction, rigidity does not become large too much even in a three-layer structure.

The characteristic constitution of the invention according to claim 3 is that the inner layer and the outer layer or the inner layer, the intermediate layer, and the outer layer have a shorter length along the axial direction and are arranged on the pole proximal side as the layer on which the outer layer is located outside. In that regard, the effect is as follows.

[Action effect]

That is, the reinforcing fibers of each other are arranged in a cross state by overlapping the third prepreg and the fourth prepreg constituting the auxiliary pattern as the outer layer disposed on the pole proximal end. As a result, the reinforcing fiber exerts a counter force in the circumferential direction, thereby exhibiting a counter force against bending failure and increasing the counter force against the shear force to avoid cracking and the like.

In addition, since the direction of the reinforcing fibers is inclined in both directions, not in the axial direction or the circumferential direction, both the main pattern and the auxiliary pattern are weaker than the case where the reinforcing fibers are arranged in the axial direction. Even if the main pattern and the auxiliary pattern are rolled up repeatedly, the rigidity does not increase.

Therefore, it can bend easily and can flexibly withstand the pull of a fish.

In addition to this, there are the following advantages. That is, when the fish are caught in the rod and cause warpage, the tensile force increases as much as the outer layer side of the pole. In consideration of such characteristics of the pole, since the crossing angle of the reinforcing fibers in the prepreg of the auxiliary pattern located on the outer layer side of the pole is small, the direction of the reinforcing fibers of the auxiliary pattern in the axial direction is a component. It is possible to increase the size and to reduce the resistance against the tensile force as compared with the cross arrangement.

As a result, it is possible to suppress deformation, cracking, and the like in bending fracture and seam, and to provide a rod that can bend easily and flexibly.

A characteristic configuration of the invention according to claim 4 is a rod for fishing rods formed by a prepreg having a group of reinforcing fibers arranged in a mixed state, wherein the poles include an inner layer and an outer layer, and the outer layer is poled. A first prepreg having a group of reinforcing fibers mixed and disposed along a first inclination angle with respect to an axis, and a group of reinforcing fibers mixed and arranged in a symmetrical manner with respect to the reinforcing fiber group of the first prepreg and the long axis; A third prepreg having the reinforcing fiber group mixed and arranged along the second inclination angle which is an inclination angle smaller than the first inclination angle with respect to the long axis, and the second prepreg overlapping with the second prepreg; Overlaying the fourth prepreg having the reinforcing fiber group of the leg and the reinforcing fiber group arranged in a symmetrical manner with respect to the long axis And the point that Sanctuary configuration, the functions and effects are as follows.

[Action effect]

The invention according to claim 4 replaces the inner and outer layers in the invention according to claim 1, and the inclination angle of the reinforcing fibers with respect to the long axis is as small as the inside. That is, in this case, since the component in the circumferential direction of the reinforcing fiber is larger than that of the outer layer, flexural fracture can be strengthened. The fact that the component in the circumferential direction becomes large means that the component in the direction of the pole axis in the outer layer is decreasing, so that the counter force against the bending of the pole tends to decrease, and this makes the pole easy to bend, and thus the pole bending It is easy to adjust the configuration.

A characteristic configuration of the invention according to claim 5 is a rod for fishing rods formed by a prepreg having a group of reinforcing fibers arranged in a mixed state, wherein the rod includes an inner layer, an intermediate layer, and an outer layer, and the outer layer. And a first prepreg having a reinforcing fiber group mixed and disposed along a first inclination angle with respect to the long axis, and a reinforcing fiber group arranged in a symmetrical manner with respect to the reinforcing fiber group of the first prepreg and the long axis. A third prepreg having a reinforcing fiber group mixed and arranged along the second inclination angle which is an inclination angle smaller than the first inclination angle with respect to the long axis, and the second prepreg having an overlapping configuration; A fourth prepre having a group of reinforcing fibers of the three prepregs and a group of reinforcing fibers mixed and disposed symmetrically with respect to the long axis; And a fifth prepreg having a group of reinforcing fibers mixed and arranged along a third inclination angle, the inclination angle smaller than a first inclination angle with respect to a long axis, and the inclination angle greater than the second inclination angle with respect to a long axis. The reinforcing fiber group of the prepreg and the 6th prepreg having the reinforcing fiber group mixed and arranged in a state symmetrical with respect to the said long axis are superimposed, and the effect is as follows.

[Action effect]

The invention according to claim 5 replaces the inner and outer layers in the invention according to claim 2, and the inclination angle of the reinforcing fibers with respect to the long axis is as small as the inside. That is, in this case, since the component in the circumferential direction of the reinforcing fiber is larger than that of the outer layer, flexural fracture can be strengthened. The fact that the component in the circumferential direction becomes large means that the component in the direction of the pole axis in the outer layer is decreasing, so that the counter force against the bending of the pole tends to decrease, and this makes the pole easy to bend, and thus the pole bending It is easy to adjust the configuration.

The characteristic constitution of the invention according to claim 6 is that the inner layer and the outer layer, or the inner layer, the intermediate layer, and the outer layer are shorter along the axial direction and arranged on the pole proximal side as the layer on which the inner layer is located inside. In that regard, the effect is as follows.

[Action effect]

That is, after the first prepreg and the second prepreg are configured to overlap each other, the reinforcing fibers are cross-linked with each other by overlapping the third prepreg and the fourth prepreg constituting the inner layer disposed on the pole proximal end. Arrange by arranging. As a result, the reinforcing fiber exerts a counter force in the circumferential direction, so that the reinforcing fiber is located on the inner side and exerts a counter force against bending failure, and the counter force against the shear force can be increased to prevent cracking and the like.

In addition, since the directions of the reinforcing fibers are inclined in both directions, not in the axial direction or the circumferential direction, both the inner and outer layers are less relaxed than when the reinforcing fibers are arranged in the axial direction. Even when the main pattern and the auxiliary pattern are rolled up, the rigidity is not so large that it is not too hard.

Therefore, it can bend easily and can flexibly withstand the pull of a fish.

In addition to this, there are the following advantages. In other words, when a fish is caught in the pole and causes warpage, the tensile force is increased as much as the outer layer side of the pole. In consideration of such a characteristic of the pole, since the crossing angle of the reinforcing fiber in the prepreg of the auxiliary pattern positioned on the outer layer side of the pole is small, the direction of the reinforcing fiber of the auxiliary pattern in the axial direction is determined. It can be enlarged and there is no weakening of the force against tension in comparison with the cross arrangement.

As a result, it is possible to suppress deformation, cracking, and the like in bending fracture and seam, and to provide a rod that can bend easily and flexibly.

The characteristic structure of this invention which concerns on Claim 7 is that the length along the axial direction of each said layer is set to the same length, and the effect is as follows.

[Action effect]

In this case, since the arrangement of the reinforcing fibers is kept constant over the entire length of the pole in the axial direction, the rod of the same deflection can be obtained over the entire length. Therefore, in addition to achieving the effect of the invention according to claims 1 to 6, it has come to be able to provide a pole that can easily set the bend.
