Description

  The present invention relates to a reel leg fixing device mounted on a fishing rod and capable of attaching various fishing reels.

  Conventionally, for example, as disclosed in Patent Document 1, a moving hood and a fixed hood that are separated in the axial length direction are provided, one end of the reel leg is inserted into the fixed hood, and the other end of the reel leg is moved in the axial direction. A reel leg fixing device of a type that fixes a fishing reel by pressing with a moving hood is known. The fixed hood and the movable hood are disposed on a pipe-shaped reel seat that is attached to the outer periphery of the marshal basin, and the movable hood is fixed by rotating an operation nut disposed adjacent to the movable hood. The fishing reel is attached / detached. Usually, the moving hood and the fixed hood (hereinafter also referred to as the hood portion) of the reel leg fixing device described above are often made of a metal material, and a synthetic resin is formed on a portion (inner surface of the hood portion) where the inserted reel leg abuts. A pad portion is provided.

  By the way, recently, it has been demanded to reduce the weight of a fishing rod, and as described above, forming the hood portion with a metal material hinders weight reduction. For this reason, for example, Patent Document 2 discloses that a hood portion is formed by stacking a plurality of prepreg sheets in which a reinforcing fiber is impregnated with a synthetic resin and molding the prepreg sheet into a cylindrical shape. Further, in this Patent Document 2, the prepreg sheet overlapping portion in each layer is an area other than the leg holding portion of the reel leg so that the strength is not lowered when the hood portion is formed by stacking a plurality of prepreg sheets. Is disclosed.

  The above-described hood portion can be reduced in weight by being formed of a fiber reinforced resin material. However, in order to reduce the weight of the fishing rod, it is desirable to reduce the thickness as much as possible to reduce the weight. That is, by reducing the thickness of the hood part, the reel leg fixing device can be reduced in weight, and the level difference between the fixed reel leg and the reel seat body is reduced and the grip feeling is improved. Improvements can also be achieved.

  Patent Document 2 described above merely discloses that a plurality of prepreg sheets having different specifications are shifted from the leg holding portion in order to reduce the weight of the hood portion. It is not considered to reduce the thickness by reducing the thickness as much as possible while maintaining the strength. For this reason, unnecessary reinforcement, such as disposing a useless prepreg sheet, is provided, which causes a problem that the hood portion becomes thick and sufficient weight reduction cannot be achieved.

  In addition, Patent Document 2 discloses that when a prepreg sheet is wound around a mandrel, a notch is formed at a predetermined position to prevent wrinkles. However, the prepreg sheet is notched. If this is done, the reinforcing fiber is cut at that position, which causes a decrease in strength, breakage, or the like.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a reel leg fixing device having a hood portion that is efficiently thinned and reduced in weight while maintaining sufficient strength. And

  In order to achieve the above object, a reel leg fixing device according to the present invention has an opening into which a reel leg of a fishing reel is inserted, and is a cylindrical hood formed by laminating a plurality of prepreg sheets. The hood portion is configured to move in the axial direction by an operation nut, and the hood portion has a greater proportion of reinforcing fibers oriented in the circumferential direction on the opening side than on the operation nut side. .

  According to the reel leg fixing device having the above-described configuration, the cylindrical hood portion is formed by stacking a plurality of prepreg sheets, so that the weight can be reduced. In this case, when the reel leg is inserted and fixed to the hood portion, a load that spreads in the circumferential direction in the opening portion acts, but in this opening portion, the ratio of the reinforcing fibers oriented in the circumferential direction is Since it is arranged so as to be larger than the operation nut side, efficient reinforcement is possible. That is, since the hood part is efficiently reinforced without disposing a useless prepreg sheet, the hood part can be made thinner and lighter.

  According to the present invention, a reel leg fixing device having a hood portion that is efficiently thinned and lightened while maintaining sufficient strength can be obtained.

FIG. 6 and FIG. 6 are cross-sectional views showing the configuration of the moving hood formed by the prepreg sheet shown in FIG.

  The reel leg fixing device 10 includes a reel sheet main body (hereinafter referred to as a main body) 11 formed in a cylindrical shape that is externally fitted to the main shaft 3. The main body 11 is integrally formed of, for example, synthetic resin, and includes a mounting surface 12 on which the reel legs 71 of the fishing reel 70 are mounted, and a fixed hood 13 disposed on the tip side of the mounting surface 12. And a moving hood 15 disposed on the base end side of the mounting surface 12.

  The fixed hood 13 includes a hood portion 13A that is integrally formed with the main body 11 and bulges so as to accommodate the tip end leg portion 71a of the reel leg 71. The tip end leg portion 71a of the reel leg 71 includes: It is inserted through the opening 13a of the hood portion 13A. The hood portion 13 </ b> A may be formed separately from the main body 11 and integrated with the main body 11, similarly to the hood portion of the moving hood described later.

  The movable hood 15 is configured to be movable along the axial direction, and includes a hood portion 15 </ b> A formed as a separate body from the main body 11. The hood portion 15A of the present embodiment includes a bulging portion 15a that bulges so as to accommodate the base end side leg portion 71b of the reel leg 71, and a cylindrical portion 15b that is integrally formed on the base end side of the bulging portion 15a. It has. That is, the bulging portion 15a has a shape that gradually rises as the arc region of a predetermined range on the outer periphery of the cylindrical portion 15b moves to the tip side, and the proximal end leg portion 71b of the reel leg 71 It is inserted through the opening 15c of the bulging portion 15a.

  A pad member 16 is disposed on the inner side of the bulging portion 15a so as to be in pressure contact with the surface of the base end side leg portion 71b of the reel leg 71 to be inserted. The pad member 16 is a portion that is pressed against the surface of the base end side leg portion 71b of the reel leg 71 when the moving hood 15 is moved toward the fixed hood side, and has a function of firmly fixing the reel leg. . That is, the pad member 16 is formed in a shape corresponding to the surface of the base end side leg portion 71 b of the reel leg 71, and the protrusion 16 a is fitted into the hole 15 d formed in the bulging portion 15 a of the moving hood 15. Thus, it is integrated with the inner surface of the bulging portion 15a.

  A male screw portion 11a is integrally formed on the base end side of the main body 11, and an operating nut 18 that moves along the axial direction by being rotated is screwed into the male screw portion 11a. . The operation nut 18 has a front end engaged with a hood portion 15A (cylindrical portion 15b) of the movable hood 15. The engagement relationship here is that when the operation nut 18 is rotated in the direction of tightening, the movable hood 15 is moved to the fixed hood without rotating, and the operation nut 18 is rotated in the direction of loosening. The moving hood 15 may be moved in a direction away from the fixed hood without rotating.

  Specifically, as shown in FIG. 4A, an annular protrusion 18a is formed on an end edge 18e of the operation nut 18 on the cylindrical portion 15b side, and a locking protrusion 18f protruding radially outward is formed at the tip. It is formed by forming a locking projection 15f projecting radially inwardly on the edge 15e on the operation nut 18 side of the cylindrical portion 15b and locking the locking projection 18f and the locking projection 15f. Has been.

  According to the engagement relationship between the operation member 18 and the hood portion 15A (cylindrical portion 15b), when the operation nut 18 is rotated in the tightening direction, the operation nut 18 is screwed toward the fixed hood side, and the hood The portion 15A (cylindrical portion 15b) is moved toward the fixed hood by the contact relationship between the end edge 18e and the end edge 15e without rotating. That is, the reel leg 71 placed on the placement surface 12 is fastened and fixed by a pair of hood portions (fixed hood 13A, movable hood 15A). When the operation nut 18 is rotated in the loosening direction, the operation nut 18 is screwed away from the fixed hood, and the hood portion 15A (cylindrical portion 15b) is not rotated, and the engagement protrusions 15f and 18f are engaged. It is moved toward the direction away from the fixed hood due to the mating relationship. That is, the reel legs 71 placed on the placement surface 12 can be removed from the pair of hood portions (the fixed hood 13A and the movable hood 15A).

The hood portion 15A of the moving hood 15 is laminated so that a fiber strength reinforced resin material, specifically, a plurality of prepreg sheets having different specifications are formed in a cylindrical shape so that a certain strength can be maintained and weight reduction can be achieved. To be molded. In this case, the prepreg sheet is configured in a state in which reinforcing fibers such as carbon fiber, glass fiber, and aramid fiber are aligned in a predetermined direction or in a knitted sheet shape, and a thermoplastic resin (for example, nylon, Polypropylene, polyphenyl sulfide, thermoplastic polyurethane) or thermosetting resin (for example, epoxy resin, phenol resin, polyester resin) is impregnated as a matrix resin.
Hereinafter, the configuration of the hood portion 15A will be described in detail.

  When the tightening force on the reel leg 71 increases in the hood portion 15A, a force for expanding the opening from the surface of the proximal leg portion 71b of the abutting reel leg 71 acts on the portion of the opening 15c. . That is, when the reinforcing fibers are in the axial length direction (the axial length direction of the main shaft 3) on the opening side of the bulging portion 15a, particularly the edge region of the opening 15c, the axial length Cracks tend to occur in the direction, and the strength tends to decrease. For this reason, as will be described later, in the opening region, a prepreg sheet in which reinforcing fibers are oriented in the circumferential direction is often used so as to resist a load that attempts to widen the opening.

  Further, in the region other than the opening of the bulging portion 15a of the hood portion 15A, in the tightened state of the reel leg, although there is little load acting in the direction of expanding the opening as described above, it is along the axial length direction. A bending force is applied. For this reason, as will be described later, in the region from the opening region to the cylindrical portion 15b, a prepreg sheet in which reinforcing fibers are oriented in the axial length direction is mainly used so as to counter the load in the bending direction.

FIG. 5 is a view showing a first arrangement example of the prepreg sheet in consideration of the load acting on the hood portion 15A as described above.
The hood portion 15A is formed by winding a plurality of prepreg sheets 30 to 32 having different specifications around a mandrel 80 formed in a predetermined shape, curing the synthetic resin by heating the prepreg sheets 30 to 32, and then decentering the mandrel 80. Is done.

  On the surface of the mandrel 80, a bulging portion 80a and a cylindrical portion 80b are formed corresponding to the shape of the hood portion 15A. That is, the cylindrical portion 80b has a circular cross section, and is a portion that forms the cylindrical portion 15b of the hood portion 15A. Further, the bulging portion 80a is inclined so that a part in the circumferential direction of the end portion 80c of the cylindrical portion 80b (a predetermined arc range corresponding to the reel leg to be inserted) gradually rises forward ( The inclined end portion 80d corresponds to the opening 15c of the bulging portion 15a of the hood portion 15A), and is a portion that forms the bulging portion 15a of the hood portion 15A.

  In the present embodiment, the prepreg sheets (main body prepreg sheets; main body layers) 30 and 31 disposed over the entire axial length direction of the hood portion 15A and the opening of the hood portion 15A as described below with respect to the mandrel 80. The hood portion 15A is formed by winding a prepreg sheet (reinforced prepreg sheet; reinforcing layer) 32 that reinforces the region.

  On the inner layer side of the hood portion 15A, the circumferential fiber layer 30 is disposed by winding the prepreg sheet 30 in which the reinforcing fibers 30A are aligned in the circumferential direction over the axial direction (in FIG. 6, the prepreg sheet is provided). And the fiber layer as the same reference number). Here, the prepreg sheet 30 is wound with the rear edge 30b aligned with the cylindrical portion 80b of the mandrel and the front edge 30a aligned with the inclined end 80d of the bulged portion 80a of the mandrel. As a result, the reinforcing fibers oriented in the circumferential direction are arranged without being cut in the circumferential direction. Note that the front edge 30a of the prepreg sheet 30 may be cut after being wound slightly ahead of the inclined end portion 80d of the mandrel and thermally cured.

  On the outer layer side of the prepreg sheet 30 wound as described above, the axial length fiber layer 31 is disposed by winding the prepreg sheet 31 in which the reinforcing fibers 31A are aligned in the axial length direction. . The rear edge 31b and the front edge 31a of the prepreg sheet 30 are positioned and wound so as to coincide with the rear edge 30b and the front edge 30a of the prepreg sheet 30 described above. As a result, the reinforcing fibers oriented in the axial direction are also arranged without being cut along the axial direction.

  A reinforcing prepreg sheet 32 in which reinforcing fibers 32A are aligned in the circumferential direction is wound around the inner layer side of the prepreg sheet 31 (outer layer side of the prepreg sheet 30). The prepreg sheet 32 is positioned such that the rear end edge 32b is aligned with the middle part of the bulging portion 80a of the mandrel, and the front end edge 32a is aligned with the front end edge 30a of the prepreg sheet 30 and the front end edge 31a of the prepreg sheet 31. Combined and wound. In this case, the reinforcing prepreg sheet 32 may be wound from above after the prepreg sheet 30 is wound, or may be attached to the surface of the prepreg sheet 30. Alternatively, it may be attached to the back side of the prepreg sheet 31.

  The hood portion 15A formed by winding the prepreg sheets 30 to 32 described above has a structure as shown in FIG. 6 when viewed in cross-section along the axial length direction. That is, on the inner layer side, the circumferential fiber layer 30 in which the reinforcing fibers are aligned in the circumferential direction by the prepreg sheet 30 described above is disposed in the axial direction. Further, on the outer side of the circumferential fiber layer 30, a circumferential fiber layer 32 in which reinforcing fibers are aligned in the circumferential direction by the reinforcing prepreg sheet 32 is disposed on the opening 15c side. That is, the opening 15c side of the bulging portion 15a is disposed so that the ratio of the reinforcing fibers oriented in the circumferential direction is larger than that of the operation nut 18 side. Then, on the outer layer side of the circumferential fiber layers 30 and 32 as described above, the axial length fiber layer 31 in which the reinforcing fibers are aligned in the axial length direction is disposed in the axial length direction.

  In the hood portion 15A formed by the plurality of prepreg sheets 30 to 32 described above, the opening 15c side of the bulging portion 15a is thickened by an amount corresponding to the reinforcing prepreg sheet 32, as compared with the cylindrical portion 15b. Further, the locking projection 15f is formed by forming a circumferential groove at the end on the cylindrical portion 15b side.

  According to the reel leg fixing device including the hood portion 15A as described above, the cylindrical hood portion 15A is formed by laminating the plurality of prepreg sheets 30 to 32, so that the weight can be reduced. In this case, when the reel leg 71 is fixed to the hood portion 15A, a load that spreads in the circumferential direction in the opening portion acts, but in this opening portion, the ratio of the reinforcing fibers oriented in the circumferential direction is manipulated. Since it is disposed so as to be larger than the nut 18 side, no breakage or the like occurs. That is, as the entire hood part is efficiently reinforced the weak part, it is possible to efficiently reduce the thickness and weight while maintaining sufficient strength as the hood part. It becomes possible to improve grip comfort.

  Further, in this embodiment, since the circumferential fiber layer disposed in the opening portion is disposed on the inner layer side that is the reel leg side to be inserted, the strength in the opening portion can be improved efficiently. It becomes possible. Further, as described above, the reinforcing fibers oriented in the circumferential direction are arranged without being cut halfway when being wound once, so that there is no reduction in strength or peeling, and the axial length direction. Since there is no part cut off in the middle of the reinforcing fiber directed to the fiber, the strength does not decrease. Furthermore, in the opening portion, the circumferential fiber layer is increased by the amount of the reinforcing prepreg sheet 32 to increase the thickness, so that the crushing rigidity is increased and the strength against crushing can be improved.

The circumferential fiber layer is preferably disposed on the inner layer side of the opening portion as in this embodiment, but the ratio of the reinforcing fibers oriented in the circumferential direction compared to the operation nut 18 side is It only needs to be relatively large and does not have to be disposed on the inner layer side. For example, by attaching the reinforcing prepreg sheet 32 to the back surface of the prepreg sheet 31 and winding it a plurality of times, the axial length direction fiber layer and the circumferential direction fiber layer are alternately laminated in the opening region. Alternatively, it may be attached to the surface of the prepreg sheet 31. That is, the order of stacking the plurality of prepreg sheets 30 to 32 is arbitrary.
Further, regarding the ratio of the reinforcing fibers oriented in the circumferential direction, it is sufficient that the opening side is larger than the opening 15c portion (opening region) and the operation nut 18 side, and the reel leg is inserted. In the region to be formed, the circumferential fiber layer may have a substantially uniform thickness, or the thickness may gradually increase toward the opening side. Alternatively, there may be a region where the circumferential fiber layer becomes thin or a region where the circumferential fiber layer does not exist between the operation nut 18 side and the opening 15c side.

  Moreover, in this embodiment, since the axial length direction fiber layer 31 of uniform thickness is arrange | positioned over the full length of 15 A of hood parts, the intensity | strength improvement with respect to the load which acts in a bending direction can be aimed at.

FIGS. 7A and 7B are diagrams showing another embodiment of the hood portion.
In the above-described embodiment, the thickness of the hood portion 15A is made thicker on the opening side, but may be a uniform thickness over the axial length direction. In this case, since the ratio of the reinforcing fibers oriented in the circumferential direction is increased on the opening side, the circumferential fiber layer 40 disposed on the inner layer side of the bulging portion 15a is disposed as shown in FIG. In the region, the thickness is gradually increased as it moves to the opening side, and the axial length fiber layer 41 is gradually reduced in thickness as the thickness increases.

  The hood portion 15A having the circumferential fiber layer 40 and the axial length fiber layer 41 as described above can be formed by, for example, prepreg sheets 40 and 41 shown in FIG. That is, the inner layer side of the hood portion 15A is formed into a circumferential fiber layer by winding the prepreg sheet 40 in which the reinforcing fibers 40A are aligned in the circumferential direction. Here, the prepreg sheet 40 has a configuration including an inclined edge 40c such that the rear edge 40b is 1 ply with respect to the mandrel and the front edge 40a is 2 plies with respect to the mandrel. By winding the prepreg sheet 40, it is possible to gradually increase the thickness of the circumferential fiber layer 40 toward the opening side in the bulging portion 15a, as shown in FIG. 7A.

  Further, the outer layer side of the hood portion 15A is formed into an axial length direction fiber layer by winding the prepreg sheet 41 in which the reinforcing fibers 41A are aligned in the axial length direction. Here, the prepreg sheet 41 has a configuration including an inclined edge 41c so that the rear end edge 41b is two plies with respect to the mandrel and the front end edge 41a is one ply with respect to the mandrel. By winding the prepreg sheet 41, the axially long fiber layer 41 can be gradually thinned toward the opening side in the bulging portion 15a as shown in FIG. 7A. .

  Thus, while uniformizing the thickness of the hood portion 15A over the axial length direction and increasing the proportion of reinforcing fibers oriented in the circumferential direction on the opening side, while maintaining the strength more efficiently, The whole can be made thinner and lighter. In this case, in the hood portion 15A, when a large load is applied around the main rod 3 to the fishing reel while the reel legs are tightened and fixed, the distance from the center of the reel legs (the reel legs) 71, the distal end of the base end side leg 71b), the load in the bending direction increases. As described above, since the axially long fiber layer 41 is thickened on the base end side of the bulging portion 15a, the strength is more efficiently maintained as a hood portion, and the thickness and thickness are reduced. Can be achieved.

  In the above-described configuration, the ratio of the fibers oriented in the circumferential direction is gradually increased as it moves to the opening side in the region of the bulging portion 15a. However, as shown in FIG. You may comprise so that it may become substantially uniform in the area | region of 15a.

  In the above-described embodiment, the prepreg sheet in which the reinforcing fibers are aligned in one direction (circumferential direction) is used. However, a prepreg sheet knitted in a woven fabric shape may be used. For example, as shown in FIG. 9, a prepreg sheet 51 in which a reinforcing fiber 51A oriented in the circumferential direction and a reinforcing fiber 51B oriented in the axial direction are woven can be used as the main body layer. In the prepreg sheet having such a configuration, the rear end edge 51b is aligned with the cylindrical portion 80b of the mandrel (see FIG. 5), and the front end edge 51a is inclined with respect to the bulged portion 80a of the mandrel, as in the above-described embodiment. Winding is aligned with the end 80d. A reinforcing prepreg sheet 50 in which reinforcing fibers 50A are aligned in the circumferential direction is wound on the inner layer side of the prepreg sheet 51 wound in this manner. The prepreg sheet 52 is wound with its rear end edge 50 b aligned with the middle part of the bulging portion 80 a of the mandrel and with its front end edge 50 a aligned with the front end edge 51 a of the prepreg sheet 51.

  Even if the hood portion 15A is formed with the prepreg sheets 50 and 51 described above, the ratio of the reinforcing fibers oriented in the circumferential direction is arranged so that the opening side is larger than the operation nut side. It becomes possible to exhibit the same effect as the embodiment. Further, since the surface of the hood portion is a woven fabric layer in which reinforcing fibers are knitted, the reinforcing fibers can be effectively prevented from tearing or peeling, and the strength can be improved and stabilized.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously.

  As described above, in the present invention, when the hood portion of the reel leg fixing device is formed of the fiber reinforced resin material, the ratio of the reinforcing fibers oriented in the circumferential direction is larger on the opening side than on the operation nut side. By doing so, there is a feature in that the strength is efficiently improved to reduce weight and thickness. For this reason, about the prepreg which shape | molds a food | hood part, it can change variously about the structure of a kind, elastic modulus, resin impregnation amount, thickness, etc. of a reinforcing fiber, a lamination | stacking state, etc. Further, in the above-described embodiment, in order to improve the strength against bending, the reinforcing fiber oriented in the axial length direction is used. However, the reinforcing fiber oriented in the oblique direction having a predetermined angle with respect to the axial length direction is used. It may be used. By using such reinforcing fibers oriented in the oblique direction, it is possible to improve the strength of the bulging portion 15a and the cylindrical portion 15b in the twisting direction.

  The cylindrical portion 15b of the hood portion 15A may not have reinforcing fibers oriented in the circumferential direction, but is a mating portion with the operation nut 18 and has a perfect circle, so there is a circumferential fiber layer. It is preferable to do. Further, the opening side of the hood portion 15A may be constituted only by the circumferential fiber layer, but it is preferable that an axial length direction fiber layer, a woven fabric layer, and a diagonal direction fiber layer exist. In this case, by using a prepreg in which the reinforcing fibers are oriented in three directions including the circumferential direction, a hood portion that is efficient, lightweight, and excellent in strength can be obtained.

The hood portion 15A of the reel leg fixing device described above has the configuration having the bulging portion 15a, but the hood portion may have a configuration without the bulging portion. For example, as shown in FIGS. 10 and 11, the hood portion 15 </ b> A of the movable hood 15 is configured by a cylindrical portion 15 b, and the bulging portion is not formed while maintaining the same outer diameter as the outer diameter of the operation nut 18. It is also possible to form the opening 15c for inserting the reel leg. In such a configuration, the pad member 16 attached to the inner surface of the hood portion 15A is made slightly thicker than the configuration shown in FIG. 3 and formed into a shape having an inner surface corresponding to the reel leg to be inserted. Just do it. According to such a hood portion 15A, the mandrel for forming the hood portion can be formed in a columnar shape, and the prepreg sheet winding operation as described above can be easily performed.
Further, the above-described configuration may be applied to the hood portion 13A of the fixed hood 13. In this case, the fixed hood may be configured such that the ratio of the reinforcing fibers in the circumferential direction is larger on the opening side than on the base end side. Further, the hood portion molded as described above may be coated for improving the appearance and protecting the surface, or may be vapor-deposited with metal or ceramics.
