Description

  The present invention is a state in which the small-diameter casing is extended with respect to the large-diameter casing by pressing the outer peripheral surface of the base-side end of the small-diameter casing to the inner peripheral surface of the tip-side end of the large-diameter casing. It relates to the structure of the mating part of the swinging rods held on.

  In order to construct a large-diameter frame, a prepreg sheet in which reinforcing fibers along the axial direction or along the circumferential direction are arranged in a line is formed in a length extending over the entire length of the ridge, and along the axial direction from the main pattern. The reinforcing pattern formed to have a short length is overlapped (see Patent Document 1).

JP-A-2005-245468 (paragraph numbers [0013] to [0015] and FIG. 1)

  In the above configuration, the large-diameter casing side mating portion is configured such that the main pattern superimposed over a plurality of layers at the tip end portion of the large-diameter casing is superimposed on the reinforcing pattern. For this reason, the mating part is too rigid, and the mating part is difficult to bend and causes tension, and the bending of the heel other than the mating part and the bending at the mating part are not smoothly connected. It was difficult to make a flexible whisper corresponding to the movement of the fish.

  An object of the present invention is to provide a mating part structure of a swinging rod that can be flexed by removing the tension at the mating part by adding a device to the combination of the main pattern and the reinforcing pattern. is there.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is that a prepreg sheet in which reinforcing fibers are aligned and arranged in the circumferential direction of the ridge, the width along the circumferential direction of the ridge is a length corresponding to one ply and the length over the entire length of the ridge. And forming a prepreg sheet knitted in a state in which reinforcing fibers intersect with each other as a reinforcing pattern having a shorter length along the axial direction than the first main pattern, and in the axial direction Forming a prepreg sheet in which reinforcing fibers are aligned and arranged as a second main pattern having a length shorter than the length along the longitudinal axis direction of the first main pattern,
To constitute the large-diameter housing, the first main pattern is disposed as an inner layer, the reinforcing pattern is disposed on the heel side as an outer layer, and the second main pattern is placed at the base of the reinforcing pattern. The reinforcing fiber is arranged on the side, and the reinforcing fiber is arranged in an inclined state in which the reinforcing fiber is arranged in an inclined state intersecting the saddle axis.

[Action]
That is, although the first main pattern for one ply is arranged on the inner layer, only the reinforcing pattern is arranged at the position corresponding to the mating portion in the second layer. The number of turns of the main pattern can be reduced as compared with the case where the main patterns for a plurality of plies are arranged.
In addition, since the reinforcing pattern is set in an inclined state in which the direction in which the reinforcing fibers are disposed intersects the heel axis direction, it functions to reduce the rigidity of the heel itself. In other words, when a fish catches a needle, a bending moment acts on the fishing rod and a tensile force along the axial direction acts on the cross-section of the rod, but when reinforcing fibers are arranged in the axial direction, the most counteracting force against that tensile force Becomes higher. On the other hand, when arranged in a state of being inclined with respect to the axial direction as in the present invention, since the opposing force is countered by the axial force, the opposing force is low and the rigidity is reduced accordingly. .

〔effect〕
Accordingly, the strength configuration of the heel side end portion is constructed using the reinforcing pattern as a main component, and thus it is not necessary to superimpose the main pattern on a plurality of layers. Also, coupled with setting the direction of reinforcing fiber in the reinforcing pattern to be inclined with respect to the vertical axis direction, the rigidity can be reduced, the feeling of tension at the mating part can be eliminated, and flexible It has become possible to provide a mating part structure for a swinging hook that can be rolled.

  The characteristic configuration of the invention according to claim 2 is that, in the invention according to claim 1, the heel side end of the reinforcing pattern and the heel side end of the second main pattern are arranged so as to overlap each other. The effects are as follows.

[Function and effect]
That is, the reinforcing pattern and the second main pattern are overlapped with each other by overlapping the heel side end portion of the reinforcing pattern and the heel side end portion of the second main pattern, thereby reinforcing the reinforcing pattern. Since the reinforcing fiber that constitutes the reinforcing fiber and the reinforcing fiber that constitutes the second main pattern are mixed at the time of firing and can be connected, the connection state of the reinforcing pattern and the second main pattern can be strengthened.

  The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the first main pattern is wound around the mandrel, and the second main pattern and the reinforcing pattern are wound around the first main pattern. And forming the large-diameter casing by removing the molding tape after firing and subjecting it to a polishing treatment to form the large-diameter casing. Is as follows.

[Function and effect]
When the second main pattern and the reinforcing pattern are wound, the first main pattern in which the reinforcing fibers are arranged in the circumferential direction is arranged on the inner side. As compared with the case where the wire is wound, the joining state of the reinforcing pattern and the second main pattern can be stabilized.

  According to a fourth aspect of the present invention, in the invention according to the third aspect, the buttock side end portion of the reinforcing pattern is formed in an extended portion in which the width along the circumferential direction of the heel is narrowed toward the buttock side. In addition, the extended portion of the reinforcing pattern is overlaid on the outer peripheral surface of the tip side end portion of the second main pattern.

[Function and effect]
The portion where the reinforcing pattern is overlapped with the second main pattern is an extended portion where the width along the circumferential direction of the heel decreases toward the buttock side, so that a portion with a constant width along the circumferential direction of the heel is overlapped Compared to the case, an increase in rigidity due to overlap can be suppressed.
In addition, since the extension portion is formed in a state where the width along the circumferential direction of the heel decreases toward the buttock side, as described in the invention according to claim 3, the forming tape is formed in a spiral shape. As the tape is wound around, the molding tape can be spirally wound along the hypotenuse (side adjacent to the two main patterns) of the extended portion. By this, when the side part adjacent to the 2nd main pattern of an extension part is formed in the side parallel to the peripheral direction of a collar, and the tape for forming is spirally wound around the side parallel to the peripheral direction It is possible to suppress disturbance of the helical pitch of the molding tape, occurrence of wrinkles, etc.

[First Embodiment]
The structure of the mating part of the swing rod will be described. As shown in FIG. 1, the outer diameter surface of the flange-side end 1 </ b> A of the small-diameter casing 1 is pressed against the inner peripheral surface of the tip-side end 2 </ b> A of the large-diameter casing 2. A mating portion structure of the swing rod that is held in an expanded state with respect to the diameter rod body 2 is configured.

  A manufacturing process of the large-diameter housing 2 will be described. As shown in FIG. 2, the first main pattern 4 </ b> A is wound around the mandrel 3. The first main pattern 4A is configured as follows.

The first main pattern 4A was formed by cutting a prepreg sheet formed by impregnating a thermosetting resin such as epoxy into a group of fibers in which reinforcing fibers c such as carbon fibers are aligned in one direction, and cutting it into a predetermined shape. Is.
As shown in FIG. 2, the first main pattern 4A is obtained by aligning the reinforcing fibers c in the circumferential direction of the ridge, and the width W1 along the circumferential direction of the ridge is cut into a width corresponding to one ply, The length L <b> 1 in the direction along the axis is a length obtained by adding a cutting margin to the entire length of the large-diameter housing 2.
The first main pattern 4A having the above shape is wound as the innermost layer.

  Next, the second main pattern 4B is wound. As shown in FIG. 2, the second main pattern 4B is similar to the first main pattern 4A in that a fiber group in which reinforcing fibers c such as carbon fibers are aligned in one direction is impregnated with a thermosetting resin such as epoxy. A prepreg sheet is formed, and the prepreg sheet is cut into a predetermined shape.

As shown in FIG. 2, the second main pattern 4B is obtained by aligning the reinforcing fibers c in the axial direction of the ridge, and the width W1 along the circumferential direction of the ridge is cut into a width corresponding to one ply, The length L2 in the direction along the axis is cut to a length shorter than the entire length of the large-diameter casing 2. It is assumed that the thickness of the second main pattern 4B is at least twice the thickness of the first main pattern 4A.
The second main pattern 4B having the shape as described above is wound as a second layer in a state where the base end of the second main pattern 4B is aligned with the base end of the first main pattern 4A.

  The shape of the second main pattern 4B on the heel tip side is a substantially triangular extension 4a. That is, the extended portion 4a forms a hypotenuse 4d in a state in which the tip end b of the winding end side 4c projects from the tip end a of the winding start side 4b in the second main pattern 4B to the tip side. It has a triangular shape.

  Next, the reinforcing pattern 5 will be described. As shown in FIG. 2, the reinforcing pattern 5 is formed by cutting a prepreg sheet formed by impregnating a reinforcing fiber group woven in a state where reinforcing fibers c such as glass fibers are crossed with a thermosetting resin such as epoxy. Formed.

  The width W1 along the circumferential direction of the reinforcing pattern 5 is cut into a length corresponding to one ply, and the shape of the reinforcing pattern 5 on the side of the flange end is an extended portion 5a having a substantially triangular shape. That is, the extended portion 5a is formed in a triangular shape by forming a hypotenuse 5d in a state where the heel side end e of the winding end side 5c is located on the heel side from the heel side end d of the winding start side 5b in the reinforcing pattern 5. Presents.

As shown in FIGS. 1 and 2, the reinforcing pattern 5 having the above shape is in a state in which the tip side 5e of the reinforcing pattern 5 coincides with the tip side 4e of the first main pattern 4A. Wrap in.

Here, the sheet thickness of the second main pattern 4B is 0.13 mm to 0.15 mm, and the sheet thickness of the reinforcing pattern 3 is 0.2 mm to 0.3 mm, preferably set to 0.25 mm. The
As described above, the second main pattern 4B and the reinforcing pattern 3 have different thicknesses. For example, the reinforcing fiber c is in the aligned state in the second main pattern 4B, but the reinforcing fiber c is in the reinforcing pattern 5. This is because they are knitted in a crossing state.

  Here, as the reinforcing pattern, the reinforcing fibers c are knitted in an intersecting state, and the reinforcing fibers c are disposed in a state in which the reinforcing fibers c are inclined with respect to the axis X of the reed, so that the rigidity of the reed itself is reduced. It is functioning to let you. The inclination angle θ here is suitably between 15 ° and 75 °.

  When a load is applied to the fishing rod from a direction orthogonal to the axis X, if the reinforcing fiber c is disposed in the circumferential direction of the rod, the resistance force against the load is high. On the other hand, when it arrange | positions in the state which inclines with respect to the axis X direction like this invention, since it opposes with the component force in the direction orthogonal to the axis X direction, resistance force is low. As a result, the rigidity is lowered.

In addition, since glass fibers are used as the reinforcing fibers c of the reinforcing pattern 5, since the glass fibers themselves are rich in flexibility, the rigidity is lowered.
Of course, carbon fiber may be used as long as it has a low elastic modulus. For example, a carbon fiber having a low elastic modulus of about 10 TON / mm ² may be used.

The width of minutes. In the second embodiment, the reinforcing pattern 6 has the same thickness as the second main pattern 4B.

  Similarly to the case of the first embodiment, after winding the first main pattern 4A for one ply, the second main pattern 4B is wound for one ply. Next, the reinforcing pattern 6 is wound by two plies so as to be adjacent to each other on the tip side of the second main pattern 4B. When the reinforcing pattern 6 is wound for one ply, the oblique side 6A of the reinforcing pattern 6 is wound in a state of being in contact with the tip of the second main pattern 4B that has been wound first.

  When the reinforcing pattern 6 is wound by one ply and then further wound by another ply, the heel side portion of the reinforcing pattern 6 is wound on the first ply portion that has been wound first. At the same time, the extended portion 6a located on the heel side is overlaid on the outer peripheral surface of the heel side end of the second main pattern 4B. As a result, as shown in FIG. 4, the outer peripheral surface of the reinforcing pattern 6 is in a state without a step.
