Description

The present invention relates to a rod body for a fishing rod.

As a rod body for a fishing rod, a rod body formed of a resin material or a super elastic metal material in a plate shape is known. Such a plate-shaped rod body is often used for fishing small fish such as smelt.

A conventional plate-shaped rod body is disclosed in, for example, Japanese Patent Laid-Open No. 2009-207358. As described in the publication, such a plate-shaped rod body is obtained by laminating a plurality of prepreg sheets in which reinforcing fibers such as glass fibers and carbon fibers are impregnated with a synthetic resin.

The tip rod is desired to have low bending rigidity near the tip end and high bending rigidity near the base end end. The tip rod has such a bending rigidity profile that the tip easily bends following the pulling of the fish, so it is easy for anglers to notice the hit, and because the bending rigidity near the base end is large, it is easy to catch the fish caught. Can be raised to. Such an ideal bending rigidity profile is realized by forming the rod body such that the rod body becomes thinner as it approaches the tip from the base end.

JP, 2009-207358, A

When a rod body is formed of a prepreg sheet containing low elasticity glass fiber as a reinforcing fiber, a small bending rigidity near the tip end is easily achieved, but it is difficult to obtain a large bending rigidity near the base end. In order to realize a large bending rigidity near the base end of the rod body, it is necessary to increase the thickness near the base end of the rod body. However, increasing the thickness of the rod body near the base end increases the weight of the rod body.

When a rod body is formed of a prepreg sheet containing highly elastic carbon fibers as reinforcing fibers, it is possible to obtain a large bending rigidity near the base end, but it is difficult to obtain a small bending rigidity at the tip end. In order to realize a small bending rigidity near the tip of the rod body, it is necessary to reduce the thickness near the tip of the rod body. However, if the thickness near the tip of the rod body is reduced, the thinned portion is likely to be damaged.

As described above, with a rod body formed of a single material, it is difficult to realize an ideal bending rigidity profile of low bending rigidity near the tip end and high bending rigidity near the base end.

One of the objects of the present invention is to provide a rod body for a fishing rod which has a low bending rigidity near the tip and a high bending rigidity near the base end.

One of the more specific objects of the present invention is to reduce the weight of a fishing rod body having a low bending rigidity near the tip end and a high bending rigidity near the base end.

One of the more specific objects of the present invention is to suppress damage near the tip of a rod body for a fishing rod, which has a low bending stiffness near the tip and a high bending stiffness near the base end.

Other objects of the invention will be apparent with reference to the entire specification.

A rod body for a fishing rod according to an embodiment of the present invention is made of a first material, has a plate-shaped main body extending in a length direction from a base end to a tip, and has a Young's modulus larger than that of the first material. And a reinforcement provided at both ends in the width direction of the main body. In the embodiment, the reinforcing body has a first width at a first position in the length direction and a second position that is closer to the tip than the first position in the length direction. The second width is smaller than the first width.

In this embodiment, the reinforcing body made of the second material having a large Young's modulus is formed wider at the position near the base end. Therefore, the fishing rod body has greater bending rigidity at the first position near the base end than at the second position near the tip.

According to this embodiment, the reinforcing body made of the second material having a large Young's modulus achieves a large bending rigidity at the second position near the base end. Therefore, in the fishing rod body, the thickness and width at the first position required to obtain the same bending rigidity are small as compared with the case where the entire rod body is formed of the first material. I'm done.

In one embodiment of the present invention, the reinforcing body may be provided at both ends in the width direction of the main body in the entire section from the base end to the tip of the main body.

In another embodiment of the present invention, the reinforcing body extends from the base end of the main body to a fourth position that is apart from the distal end of the main body along the length direction toward the base end by a predetermined distance. May be provided at both ends in the width direction of the main body. In this case, the reinforcing body is not provided in the section from the fourth position to the tip.

According to the embodiment, since the reinforcing body is not formed in the section from the fourth position of the main body to the tip, a small bending rigidity can be obtained near the tip. In this embodiment, the body made of the first material having a small Young's modulus provides a small bending rigidity near the tip. Therefore, in the fishing rod body, the vicinity of the tip of the rod body can be formed thicker than in the case of forming the entire rod body with the second material having a high Young's modulus. Thereby, damage can be suppressed near the tip of the rod body for the fishing rod.

The fishing rod body according to an embodiment of the present invention further includes a fishing line guide having legs, and a fixing member wound around the legs, the main body, and the reinforcing body of the fishing line guide. ..

According to this embodiment, since the fixing member is wound around the main body and the reinforcing body, it is possible to prevent the reinforcing body from being separated from the main body.

Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. In addition, the same reference numerals are given to common components in each drawing. It should be noted that the drawings are not necessarily drawn to scale for convenience of explanation.

FIG. 1 is a perspective view schematically showing a fishing rod 1 according to an embodiment of the present invention. As shown in FIG. 1, a fishing rod 1 according to an embodiment of the present invention includes a tip rod body 2 formed in a flat plate shape, a base rod body 3 for holding the tip rod body 2, and the base rod. A reel 4 provided on the body 3 and a plurality of fishing line guides 6 attached to the upper surface 2c of the tip rod body 2 for guiding the fishing line 8 fed from the reel are provided.

In the illustrated embodiment, the tip rod body 2 is formed such that its upper surface 2c is flat. The fishing line guide 6 includes an annular ring portion 6a into which the fishing line 8 is inserted, and a pair of leg portions 6b extending from both ends of the ring portion 6a and placed on the upper surface 2c of the tip rod body 2. Have. The fishing line guide 6 is formed, for example, by bending a linear member. This linear member is made of, for example, a stainless alloy, an aluminum alloy, a titanium alloy, or an alloy material other than these. The wire diameter of the wire member is, for example, 0.3 mm to 1 mm.

The fishing line guide 6 is fixed to the tip rod body 2 by winding a fixing member 7 around the leg portion 6b and the tip rod body 2. The fixing member 7 is a thread made of fibers or the like, a wire made of metal, or any other known linear member used for fixing the fishing line guide to the rod body. The fixing member 7 may be a sheet-shaped member such as a prepreg sheet.

A cylindrical opening is formed at the tip of the base rod body 3. A holding member 5 formed in a cylindrical shape is attached to this opening. A slit 9 is formed at the tip of the holding member 5. The tip end of the tip rod body 2 is sandwiched by the slit 9. Thus, in one embodiment of the present invention, the tip rod body 2 is held by the base rod body 3 via the holding member 5.

Since the tip rod body 2 is formed in a flat plate shape, the bending rigidity in the width direction is higher than the bending rigidity in the thickness direction. Therefore, by using the tip rod body 2, an angler can easily detect a small fish such as a smelt.

Next, with reference to FIGS. 2 to 7, the tip rod body 2 according to an embodiment of the present invention will be described. 2 is a plan view of the tip rod body 2, FIG. 3 is a side view of the tip rod body 2, and FIG. 4 is a view perpendicular to the central axis A of the tip rod body 2 passing through point P1 of FIG. FIG. 5 is a cross-sectional view (a cross-sectional view taken along the line I-I of FIG. 2) looking from the cross-section toward the tip 2b, and FIG. 5 shows a cross-section of the tip 2b of FIG. FIG. 6 is a cross-sectional view (a cross-sectional view taken along the line II-II in FIG. 2) viewed in the direction, and FIG. 6 is a cross-sectional view viewed in the direction of the tip 2b from the cross-section perpendicular to the central axis A through the point P3 in FIG. FIG. 7 is a view (a cross-sectional view taken along the line III-III in FIG. 2), and FIG. 7 is a cross-sectional view of the direction of the tip 2b from the cross section passing through point P4 in FIG. 2 and perpendicular to the central axis A (of FIG. 2). FIG. 4 is a sectional view taken along line IV-IV).

In the present specification, the “width” direction, the “length” direction, and the “thickness” direction of the tip rod body 2 are respectively the “X” direction and the “X” direction in FIG. 2 unless otherwise understood in the context. The directions are “Y” and “Z”. The center axis A of the tip rod body 2 is a line where a plane passing through the center of the tip rod body 2 in the width direction (X direction) and a plane passing through the center of the rod body 2 in the thickness direction (Z direction) intersect.

As shown in these figures, the tip rod body 2 is formed in a flat plate shape extending in the length direction (Y direction) from the base end 2a to the tip 2b.

Specifically, the right side surface 11a and the left side surface 11b in the illustrated embodiment are a part of the side surface of the cylinder. The right side surface 11a and the left side surface 11b may be flat flat surfaces.

The base end of the main body 11 coincides with the base end 2a of the tip rod body 2, and the tip end of the main body 11 coincides with the tip 2b of the tip rod body 2. Therefore, in this specification, both ends in the length direction of the tip rod body 2 and both ends in the length direction of the main body 11 may be described without particularly distinguishing them. For example, in the present specification, the base end of the main body 11 is also referred to as the base end 2a without distinguishing from the base end 2a of the tip rod body 2, and the tip of the main body 11 is also distinguished from the tip 2b of the tip rod body 2. It may be referred to as the tip 2b.

The main body 11 is formed in a flat plate shape extending in the length direction (Y direction) from the base end 2a to the tip 2b. In the illustrated embodiment, the main body 11 is formed so that its width becomes narrower (its length in the X direction becomes shorter) as it approaches the tip end 2b from the base end 2a. Therefore, comparing the width of the main body 11 at the base end 2a and the width of the main body 11 at the distal end 2b, the former is larger.

The shape of the main body 11 applicable to the present invention is not limited to the one described in this specification.

The distance is L4. The distance from the base end 2a to the tip 2b, that is, the length of the tip rod body 2 is L. In the illustrated embodiment, L1<L2<L3<L4<L is established. The position P1, the position P2, the position P3, and the position P4 can be arranged at arbitrary positions as long as the relationship of L1<L2<L3<L4<L is satisfied.

As shown in FIG. 3, the reinforcing body 12 is formed so that the thicknesses at positions P1, P2, P3, and P4 are T1, T2, T3, and T4, respectively. In the illustrated embodiment, the reinforcing body 12 is formed so that the thickness thereof decreases as it approaches the distal end 2b from the proximal end 2a. That is, in the illustrated embodiment, T1>T2>T3>T4. In another embodiment of the present invention, the reinforcing body 12 may be formed such that T1=T2>T3>T4. In another embodiment of the present invention, the reinforcing body 12 may be formed such that T1>T2=T3>T4.

In another embodiment of the present invention, the reinforcing body 12 may be formed to have a uniform thickness from the base end 2a to the tip 2b. In the present specification, when it is explained that the thicknesses at two points are equal to each other, a difference in thickness between the two points due to manufacturing error is allowed.

In one embodiment of the present invention, the reinforcing body 12 is provided on the right side surface 11a and/or the left side surface 11b of the main body 11 in the entire section from the base end 2a to the position P4, and in the section from the position P4 to the tip 2b.

The right side surface 12a and the left side surface 12b may be curved curved surfaces.

The width of the reinforcing body 12 will be further described with reference to FIGS. 4 to 7. As described above, FIG. 4 is a cross-sectional view of the tip 2b taken from a cross section that passes through the point P1 of FIG. 2 and is perpendicular to the central axis A of the tip rod body 2 (a cross-sectional view taken along line I-I of FIG. 2). Is. As shown in FIG. 4, the reinforcing body 12 is formed to have a width W1 at a position P1 apart from the base end 2a of the tip rod body 2 by L1. As shown in FIG. 5, the reinforcing body 12 is formed to have a width W2 at a position P2 which is separated from the base end 2a of the tip rod body 2 by L2. As shown in FIG. 6, the reinforcing body 12 is formed to have a width W3 at a position P3 separated from the base end 2a of the tip rod body 2 by L3. In the illustrated embodiment, the reinforcing body 12 extends only in the length direction from the base end 2a to the position P4, and therefore the reinforcing body 12 is not shown in FIG. 7 showing a cross section passing through the position P4. ..

4 to 6, the distance between the right side surface 11a of the main body 11 and the right side surface 12a of the reinforcing body 12 is shown as the width of the reinforcing body 12. The distance between the left side surface 11b of the main body 11 and the left side surface 12b of the reinforcing body 12 may be the width of the reinforcing body 12. The distance between the right side surface 11a of the main body 11 and the right side surface 12a of the reinforcing body 12 and the distance between the left side surface 11b of the main body 11 and the left side surface 12b of the reinforcing body 12 may be equal to each other. It can be different.

In one embodiment of the present invention, the reinforcement 12 is configured such that the widths W1, W2, and W3 at the positions P1, P2, and P3 respectively satisfy the relationship of W1>W2=W3.

In one embodiment of the present invention, the main body 11 is formed of a fiber-reinforced resin obtained by impregnating a reinforcing resin having a relatively low Young's modulus with a matrix resin. The relatively low Young's modulus reinforcing fibers contained in the main body 11 are, for example, glass fibers, aramid fibers, or alumina fibers. The relatively low Young's modulus reinforcing fibers contained in the body 11 have a Young's modulus in the range of 50 GPa to 200 GPa.

In one embodiment of the invention, the body 11 is formed from a superelastic alloy material. The superelastic alloy material for the main body 11 is, for example, a Ni—Ti alloy or a Fe—Al alloy. As the superelastic alloy material for the main body 11, any superelastic alloy material having a Young's modulus in the range of 10 GPa to 100 GPa can be used.

In one embodiment of the present invention, the main body 11 is made of a super elastic resin material. The superelastic resin material for the main body 11 is, for example, polyphenyl salsan (PPSU). As the superelastic resin material for the main body 11, any superelastic resin material having a Young's modulus in the range of 3 GPa to 10 GPa can be used.

In one embodiment of the present invention, the reinforcing body 12 is formed of a material having a Young's modulus larger than that of the material of the main body 11. The reinforcing body 12 is formed of, for example, a fiber reinforced resin obtained by impregnating a reinforced fiber having a relatively high Young's modulus with a matrix resin. The relatively high Young's modulus reinforcing fibers contained in the main body 11 are, for example, PAN-based carbon fibers, aramid fibers, or boron fibers. The relatively high Young's modulus reinforcing fibers contained in the reinforcing body 12 have a Young's modulus in the range of 200 GPa to 400 GPa.

When comparing the Young's modulus of the fiber-reinforced resin containing the reinforcing fiber, the influence of the matrix resin can be ignored and the Young's modulus of the reinforcing fiber can be represented as a representative. This is because the Young's modulus of the matrix resin is generally much smaller than that of the reinforcing fiber. For example, when a fiber reinforced resin containing glass fibers is used as the material of the main body 11 and a fiber reinforced resin containing carbon fibers is used as the material of the reinforcing body 12, the Young's modulus of the glass fibers is It is possible to compare the Young's modulus of the material of the main body 11 and the Young's modulus of the material of the reinforcing body 12 with Young's modulus and Young's modulus of the carbon fiber as the Young's modulus of the reinforcing body 12.

When the main body 11 and/or the reinforcing body 12 is formed of a fiber reinforced resin, a thermosetting resin such as epoxy, pismaleimide, polyimide and phenol can be used as the matrix resin of the fiber reinforced resin.

Next, with reference to Drawing 8 and Drawing 9, a manufacturing method of tip rod body 2 concerning one embodiment of the present invention is explained. FIG. 8 schematically shows the tip rod body 2 in the process of manufacturing as viewed from the direction of the upper surface 2c, and FIG. 9 schematically shows the tip rod body 2 in the process of manufacturing as viewed from the direction of the base end 2a. ing.

As shown in FIGS. 8A and 9A, first, the inner base material 111 to be the main body 11 after processing is prepared. The inner base material 111 is formed of the same material as that described above as the material of the main body 11. The inner base material 111 can be formed of, for example, a fiber reinforced resin obtained by impregnating glass fiber with a matrix resin. The inner base material 111 is made of a fiber reinforced resin obtained by impregnating a reinforcing resin having a relatively low Young's modulus other than glass fiber with a matrix resin, a super elastic alloy material such as a Ni—Ti alloy, or polyphenyl salsan (PPSU). It may be formed of a super elastic resin. In the illustrated embodiment, the inner base material 111 has a cylindrical shape. The shape of the inner base material 111 is not limited to the cylindrical shape, and may have a polygonal prism shape, a conical shape, a truncated cone shape, or any shape suitable for obtaining the main body 11 other than these. The inner base material 111 may have the same length L as the main body 11.

Subsequently, as shown in FIGS. 8B and 9B, the outer base material 112 is wound around the inner base material 111 to form the composite member 120. The composite member 120 includes an inner base material 111 and an outer base material 112 provided outside the inner base material 111. The outer base material 112 becomes the reinforcing body 12 after processing. The outer base material 112 is formed of a material having a higher Young's modulus than the material of the inner base material 111. For example, the outer base material 112 is formed from a prepreg sheet in which carbon fibers are impregnated with a matrix resin.

Then, by cutting this composite member 120 along a virtual line B by a known cutting method such as milling, the tip rod body 2 is obtained as shown in FIGS. 8(c) and 9(c). can get.

By attaching the tip rod body 2 thus obtained to the base rod body 3 and further attaching the fishing line guide 6 to the tip rod body 2, the fishing rod 1 provided with the tip rod body 2 is obtained. In one embodiment of the present invention, the fishing line guide 6 is attached to the tip rod body 2 so that its leg portion 6b straddles the position P4. As described above, in the embodiment of the present invention, the reinforcing body 12 is provided on the main body 11 in the section from the base end 2a to the position P4, and is not provided in the section from the position P4 to the tip 2b. The tip of the reinforcing body 12 is at the position P4. The tip of the reinforcing body 12 may be separated from the main body 11. By attaching the fishing line guide 6 to the tip rod body 2 so that the legs 6b thereof straddle the position P4, it is possible to prevent the tip of the reinforcing body 12 from being separated from the main body 11.

According to the above-described embodiment, the reinforcing body 12 formed of the material having the Young's modulus larger than that of the main body 11 is provided, and the reinforcing body 12 is located at the position near the base end 2a (for example, the position P1). It is formed wider than the position near the tip 2b (for example, the position P3). Therefore, the tip rod body 2 has greater bending rigidity at a position closer to the base end (eg, position P1) than at a position closer to the tip (eg, position P3).

According to the above embodiment, the reinforcing body 12 realizes a large bending rigidity in the vicinity of the base end 2a. In order to obtain bending rigidity equivalent to this with only the main body 11, the thickness of the base end of the tip rod body must be made thicker than that in the above embodiment. In the above embodiment, since the large flexural rigidity near the base end 2a is realized by the reinforcing body 12, as compared with the case where the main body 11 alone realizes the high flexural rigidity near the base end 2a, the tip rod body 2 is provided. The thickness of the can be reduced. This makes it possible to reduce the weight of the tip rod body 2 having high bending rigidity near the base end.

According to the above-described embodiment, since the reinforcing body 12 is not formed in the section from the position P4 to the tip 2b, a small bending rigidity can be obtained near the tip 2b. In this embodiment, the main body 11 made of a material having a small Young's modulus provides a small bending rigidity near the tip 2b. Therefore, in the tip rod body 2, the thickness near the tip of the tip rod body 2 should be made thicker than in the case where the entire rod body is made of a material having a high Young's modulus used for the reinforcing body 12. You can Thereby, damage to the tip 2b of the tip rod body 2 can be suppressed.

According to the above-mentioned embodiment, since the fixing member 7 is wound around the tip rod body 2, it is possible to prevent the reinforcing body 12 from peeling off from the main body 11.

Next, with reference to FIG. 10, a tip rod body 22 according to another embodiment of the present invention will be described. The tip rod body 22 includes a main body 11 and a reinforcing body 32. In the illustrated embodiment, the reinforcing body 32 is formed on both the right side surface 11a at the right end in the width direction of the main body 11 and the left side surface 11b at the left end in the width direction of the main body 11. The reinforcing body 32 may be provided only on the right side surface 11a or the left side surface 11b of the main body 11.

The reinforcing body 32 is different from the reinforcing body 12 in that it is provided on the right side surface 11 a and/or the left side surface 11 b of the main body 11 over the entire length of the main body 11 in the longitudinal direction.

The dimensions, materials, and arrangements of the components described herein are not limited to those explicitly described in the embodiments, and the components may be included in the scope of the present invention. Can be modified to have different dimensions, materials, and configurations. In addition, components that are not explicitly described in this specification may be added to the described embodiments, or some of the components described in each embodiment may be omitted.
