Description

  The present invention relates to a tubular hood used for fixing a reel to a fishing rod, and a reel rod for a fishing rod and a fishing rod including the same.

  A fishing rod reel sheet is used to fix the reel to the fishing rod. The fishing rod reel sheet is provided with a pair of hoods facing each other at a predetermined distance in the rod axis direction, and the reels are fixed to the fishing rod by inserting both ends of the reel legs into the hoods. An example of the structure of the fishing rod reel sheet is a so-called pipe sheet having a cylindrical reel sheet body that is externally mounted on a rod body as disclosed in Patent Document 1, for example. A fixed hood portion into which one end portion of the reel leg is inserted is integrally formed at one end portion in the axial direction of the leg mounting surface where the reel leg is placed in the reel seat body. In order to hold the other end, a cylindrical movable hood body is externally mounted on the reel seat body. The movable hood body is movable in the axial direction with respect to the reel sheet main body, and includes a metal cylindrical hood from the viewpoint of strength. The cylindrical hood includes a leg holding portion whose one circumferential portion bulges radially outward on one end side in the radial direction, and the other end of the reel leg is inserted into the leg holding portion. Then, by bringing the movable hood body closer to the fixed hood portion of the reel seat body, the reel legs are held together with the fixed hood portion, thereby fixing the reel to the fishing rod. Conversely, the holding state of the reel legs is released by moving the movable hood body away from the fixed hood portion, whereby the reel can be removed from the fishing rod.

  By the way, in recent years, fishing rods have been required to be lighter, and fishing rod reel seats, which are constituent members of the fishing rod, have been required to be further lightened. Since it is made of metal from the viewpoint of strength, its weight reduction is naturally limited. In addition, as in Patent Documents 2 and 3 below, a cylindrical hood may be used as the fixed hood, but in this case as well, it is necessary to reduce the weight of the cylindrical hood.

JP 2011-10582 A Japanese Utility Model Publication No. 62-198971 Japanese Utility Model Publication No. 63-28365

  Therefore, the present invention has been made in view of the above-described conventional problems, and an object thereof is to further reduce the weight of a fishing rod reel seat and a fishing rod provided therewith.

  The present invention has been made to solve the above problems, and the tubular hood of a reel seat for a fishing rod according to the present invention has one end side in the axial direction so that the end of the reel leg is inserted and held. A cylindrical hood of a fishing rod reel seat that has a leg holding part with a part in the circumferential direction bulging outward in the circumferential direction, and overlaps both side edges of a prepreg impregnated with resin in reinforcing fibers A plurality of reinforced fiber layers formed in a cylindrical shape, and the overlapping portion of the prepreg in each reinforced fiber layer is located at a place other than the place where the leg holding part is formed in the circumferential direction, and is also located in the circumferential direction with respect to each other. It is characterized by being displaced.

  In the tubular hood of the fishing rod reel sheet having the above configuration, both side edges of the prepreg obtained by impregnating the reinforcing fibers with the resin are overlapped to form a tubular shape. The overlapping portion is formed at one place in the circumferential direction. The cylindrical hood has a leg holding portion, and a large force acts on the leg holding portion from the reel legs. Accordingly, if the overlapping portion is located at a position where the leg holding portion is formed in the circumferential direction, problems in strength and durability are likely to occur. Therefore, the overlapping portion is positioned at a location other than the location where the leg holding portion is formed in the circumferential direction. Moreover, since the leg holding | maintenance part is formed in the axial direction one end part side of the cylindrical hood, the cross-sectional shape is not necessarily a perfect circle, and the cross-sectional shape also changes along the axial direction. Therefore, it is preferable to have a multilayer structure rather than a single layer structure in which only one reinforcing fiber layer is provided. Compared to the case of a single layer structure consisting of a single thick prepreg, a thin prepreg can be used, so when winding the prepreg around a mandrel, it is difficult to generate wrinkles etc. Can do. Also, prepregs having different specifications for each layer can be used. And in the case of providing a reinforcing fiber layer in this way, if the overlapping parts of each layer are arranged concentrated in one place in the circumferential direction, the place becomes locally thick, and a thin and strong cylindrical hood It becomes difficult to form. For this purpose, it is preferable to dispose the overlapping portions of each layer in the circumferential direction, whereby the overlapping portions of each layer are dispersed in the circumferential direction to achieve overall thinning, thereby reducing stress concentration. Also become.

  In particular, it is preferable that the overlapping portions of the reinforcing fiber layers adjacent to each other on the inner and outer sides are alternately shifted in the left-right direction with respect to a center line extending in the vertical direction from the front side to the back side in a cross-sectional view of the cylindrical hood. For example, when viewed from one end side in the axial direction, when the overlapping portion of the inner reinforcing fiber layer is located on the left side with respect to the center line extending in the vertical direction, the overlapping of the outer reinforcing fiber layer is The mating portion is positioned on the right side with respect to the center line extending in the vertical direction. In this way, when the overlapping portions adjacent to each other on the inner and outer sides are alternately displaced with respect to the center line extending in the vertical direction, the overlapping portions of the reinforcing fiber layers adjacent to each other inside and outside can be easily separated in the circumferential direction. In addition, the overlapping portion can be arranged with a good left-right balance with respect to the center line extending in the vertical direction.

  Moreover, it is preferable that the V-shaped notch part is formed in the place where the leg holding | maintenance part was formed among the circumferential directions at the other axial end part of a prepreg. As described above, the cylindrical hood has a cross-sectional shape that is not a perfect circle, and the cross-sectional shape also changes along the axial direction. Specifically, the other end side in the axial direction is smaller and the circumferential length is shorter than the one end side in the axial direction, which is the side on which the leg holding part is formed. The shape changes greatly. Therefore, a V-shaped notch is formed in the prepreg. The notch is formed at the end opposite to one end in the axial direction, which is the side on which the leg holding portion is formed, and is formed at the location where the leg holding portion is formed in the circumferential direction. Thus, by forming the V-shaped notch at the other axial end of the prepreg, the circumferential length at the other axial end can be made shorter than that at the one axial end. When winding around a mandrel, wrinkles are less likely to occur. Further, by forming the V-shaped notch at the leg holding portion forming portion in the circumferential direction, wrinkles are generated at the leg holding portion forming portion which is particularly prone to wrinkling in the circumferential direction. Can be suppressed.

  Furthermore, it is preferable that the notch part is each formed in the location corresponding to the right-and-left both sides of a leg holding | maintenance part among the circumferential directions. Even in the leg holding part formation area, wrinkles are likely to occur especially on the left and right sides, but by forming V-shaped notches there, the generation of wrinkles is further suppressed and the prepreg is smoothly applied to the mandrel. Can be wound.

  Moreover, it is preferable that the reinforcing fiber includes a reinforcing fiber layer made of a prepreg in which a vertical sheet along the axial direction and a horizontal sheet along which the reinforcing fiber extends along the circumferential direction are laminated. When a prepreg consisting of only longitudinal sheets along the axial direction of the reinforcing fibers is wound, the reinforcing fibers along the axial direction are likely to deviate from each other in the circumferential direction at locations where the shape has changed in the circumferential direction. Further, when a prepreg consisting of only a transverse sheet along the circumferential direction of the reinforcing fiber is wound, the reinforcing fibers along the circumferential direction are separated from each other in the axial direction when the diameter and the circumferential length change in the axial direction. It is easy to shift. Since the shape of the cylindrical hood changes in the circumferential direction and also in the axial direction, it is preferable to wind a composite type prepreg in which a vertical sheet and a horizontal sheet are laminated in advance. Thus, it is possible to suppress the reinforcing fibers from being displaced in the circumferential direction or the axial direction, thereby suppressing variations in strength in the circumferential direction and variations in the axial direction.

  In that case, it is preferable that the reinforcing fiber further includes a reinforcing fiber layer made of a prepreg that intersects while being inclined with respect to the axial direction. The reinforcing fibers in the vertical and horizontal directions in the reinforcing fiber layer formed from the composite type prepreg as described above tried to deform as if the square was deformed into a parallelogram or rhombus by external force acting after heating and firing. In this case, the reinforcing fibers intersecting while being inclined in the reinforcing fiber layer located inside or outside of the reinforcing fiber function as a bracing with respect to the reinforcing fibers in the vertical and horizontal directions, and the parallelogram of the reinforcing fibers in the vertical and horizontal directions. Or the deformation | transformation to a rhombus is suppressed. Therefore, a thin cylindrical hood can be easily obtained even if it is thin.

  The fishing rod reel sheet according to the present invention can be moved in the axial direction so as to hold a cylindrical reel sheet body that is externally mounted on the rod body and an end of the reel leg that is externally mounted on the reel sheet body. A movable hood body, and the movable hood body includes the above-described cylindrical hood.

  In the fishing reel seat of the configuration, it is possible to reduce the weight of the movable hood body by forming the cylindrical hood from the prepreg as described above, compared to a conventional metal hood. As a result, weight reduction of the fishing rod reel sheet is achieved. In addition, since the movable hood body can be made thin while reducing the weight, the level difference between the surface of the movable hood body and the surface of the reel seat body is reduced, and the sense of incongruity when gripping the reel seat for a fishing rod is reduced, making it easier to grip. Become.

  The fishing rod according to the present invention is provided with the fishing rod reel sheet.

  As described above, by forming the cylindrical hood from the prepreg, the weight can be reduced as compared with the conventional metal cylindrical hood, and the necessary strength can be ensured. Therefore, the fishing rod reel sheet can be reduced in weight compared to the conventional one, and the fishing rod provided with the same can also be reduced in weight.

  Hereinafter, a cylindrical hood and a reel rod for a fishing rod provided with the same according to an embodiment of the present invention will be described with reference to the drawings. The reel sheet for a fishing rod shown in FIGS. 1 to 3 (hereinafter simply referred to as “reel sheet 10”) is used to fix the reel to the fishing rod, and is used by being attached to the rod body 11 of the fishing rod. . The reel sheet 10 has a generally cylindrical shape called a so-called pipe sheet, and is externally mounted on the bag body 11 and fixed at a predetermined position. The reel sheet 10 is mainly used for mounting a spinning reel, and the reel is positioned below the fishing rod in a used state. Accordingly, in FIG. 1, for the sake of explanation, the leg placement surface 28 on which the reel legs are placed is illustrated as facing upward, but in FIGS. 2 and 3 showing the use state, the leg placement surface 28 is on the lower side. It is shown in a state of facing. 4 is the same orientation as FIG. 1, and FIGS. 5 to 8 are the same orientation as FIGS. In addition, let the side in which the leg mounting surface 28 exists among the circumferential directions be a front side, and let the opposite side be a back side. In FIG. 3, hatching is omitted for a cylindrical hood 16 and a connecting body 17 which will be described later. An arrow 15 indicates the axial direction.

  The reel sheet 10 includes a cylindrical reel sheet main body 29 that is externally mounted on the bag main body 11, and a movable hood unit 13 that is externally mounted on the reel sheet main body 29 and is movable in the vertical axis direction. Hereinafter, it demonstrates in order.

  The reel sheet main body 29 includes a main portion 31 that is a molded product made of synthetic resin. The main part 31 is cylindrical as a whole, and the heel body 11 is inserted through the inner peripheral surface thereof. The main portion 31 is integrally formed with a fixed hood portion 12 for holding one end portion of both ends of the reel legs. As shown in FIG. 3, the fixed hood portion 12 is formed in a thick and dome-like shape on the front side, and is located at one end of the leg placement surface 28 in the heel axis direction. It opens to the end side, and one end of the reel leg is inserted from the opening toward the one end side in the axial direction.

  A male screw portion 34 is formed at the other axial end of the main portion 31. Slide grooves 25 and 27 extending linearly in the axial direction so as to partially cut out the male threaded portion 34 are formed. The slide grooves 25, 27 reach the other end edge of the main portion 31 in the axial direction. The slide grooves 25 and 27 are formed in a total of four locations every 90 degrees in the circumferential direction, but the number and arrangement thereof are arbitrary.

  A through hole 33 is formed on each side surface of the main portion 31. The through holes 33 are located on both sides of the leg placement surface 28, and the heel body 11 can be directly touched with a fingertip or the like through the through holes 33. Reference numeral 32 denotes a wall surface of the through hole 33. Further, on the back side of the main portion 31, a thick portion 30 is formed at a position facing the leg placement surface 28 as shown in FIG.

  The movable hood unit 13 is packaged on the other end side of the reel sheet main body 29 in the axial direction. The movable hood unit 13 includes a movable hood body composed of a cylindrical hood 16 and an operation nut 14, and an operation nut 14 for moving the movable hood body in the axial direction. The operation nut 14 has a female screw portion 49 on its inner peripheral surface 48 and is screwed into the male screw portion 34 of the reel sheet main body 29. The movable hood body is positioned on one end side of the operation nut 14 in the axial direction and is locked to the operation nut 14 so as to be relatively rotatable, and is slidable in the axial direction in the slide grooves 25 and 27 of the reel seat body 29. Is engaged. Therefore, when the operation nut 14 is rotated, the movable hood body moves in the axial direction together with the operation nut 14 without rotating. When the operation nut 14 is rotated in one direction to bring the movable hood body closer to the fixed hood portion 12, both ends of the reel leg are held in the axial direction by the fixed hood portion 12 and the movable hood body, and the leg placement surface It is pressed against 28 and fixed. On the contrary, when the operation nut 14 is rotated to the other side to move the movable hood body away from the fixed hood portion 12, the fixed state of the reel legs is released and the reel can be removed from the fishing rod.

  Specifically, as shown in FIGS. 3 and 4, a circumferential groove 50 is formed on the inner peripheral surface of one end of the operation nut 14 in the axial direction, and the other end of the movable hood body in the axial direction is formed in the circumferential groove 50. The part is locked from the inside. A longitudinal groove 52 is formed on the outer peripheral surface 51 of the operation nut 14 in order to improve the operability of the rotation operation. The longitudinal grooves 52 extend in the axial direction from the end surface 53 on the other end side in the axial direction, and a plurality of the grooves 52 are formed at equal intervals in the circumferential direction in the present embodiment, but the number is arbitrary. And this may be omitted.

  The movable hood body is composed of two members. Specifically, as shown in FIG. 4, the movable hood body includes a cylindrical hood 16 positioned on the side far from the operation nut 14 and a connecting body 17 positioned on the side close to the operation nut 14.

  The cylindrical hood 16 is provided with a leg holding portion 56 in which a part in the circumferential direction bulges radially outward to hold the other end of the reel leg. The leg holding portion 56 is formed on one end side of the tubular hood 16 in the axial direction and faces the fixed hood portion 12, and the leg placement surface of the reel seat body 29 is bulged outwardly in the radial direction. A leg insertion space 58 (see FIG. 3) into which the other end of the reel leg can be inserted is formed between the first and second reel legs. That is, the leg holding portion 56 of the cylindrical hood 16 is also formed on the front side in the same manner as the fixed hood portion 12.

  As shown in FIG. 7, at least a half circumference (180 degrees) on the back side of the cylindrical hood 16 is center line C (inside the reel seat body 29) of the casket body 11 in a cross-sectional view or an arch axis direction arrow. It is an arc centered on the center line of the peripheral surface. On the other hand, the front side of the tubular hood 16 bulges outward in the radial direction from the back side so as to form the leg holding portion 56. The center part 56a in the circumferential direction of the leg holding part 56 is an arc centered on the above-mentioned center line C, and its radius is larger than the radius on the back side. Both side portions 56b in the circumferential direction of the leg holding portion 56 have a larger curvature than the central portion 56a in the circumferential direction of the leg holding portion 56.

  Further, as shown in FIG. 8, the back side of the cylindrical hood 16 has a straight shape, that is, a distance (radius) from the center line C of the rod main body 11 along the rod axis direction (axial direction). On the other hand, in the leg holding part 56 on the front side of the tubular hood 16, the distance from the center line C gradually decreases from one end side to the other end side in the axial direction. And the leg holding | maintenance part 56 is diameter-reduced, curving in the radial direction convex from the axial direction one end side to the other end side. The one end surface 54 in the axial direction of the cylindrical hood 16 is an inclined surface inclined obliquely with respect to the axial direction so that the front side is located on the other end side in the axial direction with respect to the rear side. Yes. On the other hand, the other end surface 55 in the axial direction of the cylindrical hood 16 is a vertical surface orthogonal to the axial direction. Accordingly, the length L2 in the axial direction on the back side of the cylindrical hood 16 is longer than the length L1 in the axial direction on the front side. A penetrating locking hole 57 is formed on the back side of the cylindrical hood 16 and in the vicinity of the other end surface 55 in the axial direction. The cylindrical hood 16 is made of a fiber reinforced resin, and its manufacture and detailed specifications will be described later.

  The connecting body 17 connects the cylindrical hood 16 and the operation nut 14, is locked to the operation nut 14 so as to be relatively rotatable, and is movable in the axial direction by engaging the reel seat body 29 in the radial direction. Configured. The connection body 17 is a molded product made of synthetic resin, and includes a base ring portion 18 and a pad portion 19 protruding from one end surface 37 of the base ring portion 18 as shown in FIG.

  As shown in FIG. 6, the base ring portion 18 has a ring shape as a whole, and the key portions 20, 21, 22, and 23 extending in the radial direction protrude from the inner peripheral surface 36 toward the radially inner side. It is installed. The key portions 20, 21, 22, 23 are engaged with the slide grooves 25, 27 of the reel sheet main body 29, and are movable relative to the slide grooves 25, 27 in the axial direction. The other end portions of the key portions 20, 21, 22, and 23 in the axial direction protrude from the other end surface 40 of the base ring portion 18 by a predetermined length in the axial direction, and radially outward on the outer surface of the tip portion. Thus, a locking projection 39 is projected. The key portions 20, 21, 22, and 23 are formed at a total of four locations at 90 ° intervals corresponding to the slide grooves 25 and 27 of the reel sheet 10, but are associated with all the other end portions in the axial direction. A stop convex portion 39 is formed. The key portions 20, 21, 22, and 23 can enter the inside of the operation nut 14 by bending inward in the radial direction with the other end surface 40 of the base ring portion 18 as a fulcrum. 14 is engaged with the circumferential groove 50 from the inside in the radial direction, whereby the coupling body 17 is locked to the operation nut 14 so as to be relatively rotatable. That is, the key portions 20, 21, 22, and 23 include a straight portion 38 that engages with the slide grooves 25 and 27 of the reel sheet body 29, and a locking convex portion 39 that engages with the circumferential groove 50 of the operation nut 14. I have. In addition, although the inner surface 41 of the straight part 38 is made into the surrounding surface and it is a preferable shape, it may be a flat surface and should just engage with the slide grooves 25 and 27 and can move relatively. Further, the outer diameter of the base ring portion 18 is substantially equal to the outer diameter of the operation nut 14, and therefore, smoothly continues from the outer peripheral surface 51 of the operation nut 14 to the outer peripheral surface of the base ring portion 18.

  The two key portions 21 and 23 positioned on the left and right of the four key portions 20, 21, 22 and 23 do not protrude from the one end surface 37 of the base ring portion 18, while the key portion 22 positioned on the back side The key part 20 located on the front side protrudes from the one end surface 37 of the base ring part 18 in the axial direction. A locking projection 43 that protrudes radially outward is formed on the outer surface of one end portion in the axial direction of the key portion 22 positioned on the back side. The locking projection 43 is engaged with the locking hole 57 of the cylindrical hood 16 from the inside, whereby the cylindrical hood 16 and the connecting body 17 can move together and are cylindrical via the connecting body 17. The hood 16 and the operation nut 14 are connected.

  On the other hand, the key portion 20 located on the front side also protrudes from the one end surface 37 of the base ring portion 18 in the radial direction, and the protruding portion is integrated with the pad portion 19 described above. That is, the pad portion 19 is located on the front side, and extends while being gently inclined outward in the radial direction toward one end side in the axial direction as shown in FIG. The pad portion 19 is inserted inside the leg holding portion 56 of the cylindrical hood 16, penetrates the cylindrical hood 16 in the axial direction, and a tip end portion thereof is slightly exposed from one end face 54 of the cylindrical hood 16. It becomes. Therefore, the pad portion 19 has a shape corresponding to the leg holding portion 56 of the cylindrical hood 16. A concave portion 47 is formed on the outer surface of the pad portion 19 to engage the leg holding portion 56 of the cylindrical hood 16 so as to be substantially flush with each other. Reference numerals 45 and 46 are stepped portions on the distal end side and the proximal end side of the recess 47, respectively, and the leg holding portion 56 of the cylindrical hood 16 is engaged with the recess 47 and the rear surface of the locking hole 57 of the cylindrical hood 16 is engaged. The cylindrical hood 16 is securely attached to the coupling body 17 by the engagement of the locking projections 43 on the side. Further, a flange 44 is formed on the outer surface of the distal end portion of the pad portion 19 by the stepped portion 45 on the distal end side, and the flange 44 is exposed from the cylindrical hood 16. The flange 44 covers a portion corresponding to the leg holding portion 56 of the one end surface 54 of the cylindrical hood 16 to protect that portion. Since the outer surface of the other end portion of the reel leg abuts on the inner surface 35 of the pad portion 19, the inner surface shape is formed in an arc shape in cross section corresponding to the outer surface of the other end portion of the reel leg. In the state in which the cylindrical hood 16 and the connecting body 17 are combined, there is no step between the outer peripheral surface of the base ring portion 18 of the connecting body 17 and the outer peripheral surface of the cylindrical hood 16 as shown in FIGS. It will be in the state.

  Next, detailed specifications and a manufacturing method of the cylindrical hood 16 will be described with reference to FIGS. 9 to 12. As described above, the cylindrical hood 16 is made of a fiber reinforced resin, and is manufactured using a sheet-like prepreg in which a reinforcing fiber typified by carbon fiber is impregnated with a resin. However, reinforcing fibers other than carbon fibers may be used. The tubular hood 16 is formed by winding the prepreg around a mandrel and heating and firing. The tubular hood 16 is formed with a portion in the circumferential direction bulging to form a leg holding portion 56. The circumference of the other end surface 55 is shorter than that of the one end surface 54. That is, the curvature greatly changes in a part in the circumferential direction, and only that portion becomes a small diameter toward the other end side in the radial direction. Therefore, in order to cope with such a shape having a large change in the circumferential direction and the axial direction, a V-shaped notch 60 is provided at the other axial end 70b of the prepreg 70 as shown in FIG. Is forming. Since the cutout portions 60 are formed at locations corresponding to the side portions 56b of the leg holding portion 56 of the cylindrical hood 16, the cutout portions 60 are a total of two locations. By forming the cutout portion 60 in this way, the length of the other axial end portion 70b of the prepreg 70 becomes shorter than the length of the axial end portion 70a as shown in FIG. 9B. Therefore, even if the cylindrical hood 16 has a shape that is reduced in diameter toward the other axial end, and the mandrel has a correspondingly reduced diameter, wrinkles are less likely to occur in the prepreg 70 and the prepreg is applied to the mandrel. 70 can be wrapped neatly. Further, since the prepreg 70 is most stretched in the circumferential direction at the positions of the both side portions 56b of the leg holding portion 56, the prepreg 70 can be cleaned cleanly by positioning the notches 60 on the both side portions 56b. Can be wrapped around a mandrel.

  FIG. 9 is a schematic view of the prepreg 90. When the longitudinal direction A becomes a cylindrical shape, it becomes a circumferential direction, and when the short side direction B becomes a cylindrical shape, it becomes a radial direction. The two side edge portions 70c of the prepreg 70 (both ends in the longitudinal direction A in the figure) are overlapped to form a cylinder as shown in FIG. That is, the length of the prepreg 70 is approximately one turn and is wound once around the mandrel. As shown in the figure, the prepregs 70 are overlapped so that one side edge 70c is inside and the other side edge 70c is outside, but the width W of the overlapping part 70d is 0.3 mm. ˜2 mm, preferably 0.5 mm to 1.5 mm. In addition, the position shown with the dashed-two dotted line D in Fig.9 (a) is a position cut after heat-firing, and the cylindrical hood 16 is formed only from the inner part of both the cut lines D. FIG. That is, the length of the prepreg 70 in the axial direction has a predetermined excess, and after heating and baking, both ends in the axial direction are cut by a predetermined amount to obtain a final shape.

  In this way, the reinforcing fiber layer is formed by making the prepreg 70 into a cylindrical shape, but the cylindrical hood 16 includes a plurality of such reinforcing fiber layers, in this embodiment, five layers. . An example is shown in FIG. As shown in the figure, a total of five prepregs 71, 72, 73, 74, 75 are used, and the lengths in the circumferential direction are almost equal. In the figure, the leftmost prepreg 71 is the innermost prepreg, and the rightmost prepreg 75 is the outermost prepreg. The first prepreg 71 in order from the inside is for constituting a bias layer that functions as an oblique reinforcing material, and the so-called bias material in which the reinforcing fibers intersect with each other while being inclined at a predetermined angle with respect to the axial direction. A so-called prepreg is used. The angle of the reinforcing fiber with respect to the axial direction is, for example, about 45 degrees. Although the bias layer is provided in the innermost layer, for example, it may be provided in the second, third, or fourth from the inside, and the position thereof is arbitrary.

  The second to fourth prepregs 72, 73, 74 from the inside are the main layers of the cylindrical hood 16, and they have the same specifications, and prepregs that are also referred to as so-called vertical and horizontal bonded materials are used. As shown in FIG. 12, the second to fourth prepregs 72, 73, and 74 are laminated and integrated with a longitudinal sheet 81 in which reinforcing fibers are along the axial direction and a lateral sheet 82 in which reinforcing fibers are along the circumferential direction. The laminated sheet 83 is made of.

  The outermost prepreg 75 is mainly used for design, but also contributes to strength. The prepreg 75 of the outermost layer includes a woven cloth (biaxial woven prepreg, triaxial woven prepreg, four-axis woven prepreg) in which a reinforcing fiber is plain woven, or a prepreg having two directions (0 degree, So-called four-axis prepregs that are stacked and integrated in four directions (90 degrees, -45 degrees, 45 degrees), or a thin slit tape-shaped prepreg that is plain woven in four directions, etc. are used. The The specifications of the outermost prepreg 75 can be easily changed. Therefore, by changing the specification, the surface pattern of the cylindrical hood 16 can be easily changed without changing the mold or the like. Moreover, since it can be colored by painting after baking, a pattern rich in variations can be applied. After winding the outermost prepreg 75, a molding tape is wound and tightened and fired as usual.

  As described above, the tubular hood 16 is composed of a total of five reinforcing fiber layers, and there is an overlapping portion 70d for each layer. The overlapping portions 70d are all present within a predetermined range in the circumferential direction. Specifically, as shown in FIG. 7, all five overlapping portions 70 d are positioned at a location 90 other than the location where the leg holding portion 56 is formed in the circumferential direction. More preferably, all the overlapping portions 70d are positioned not on the front side but on the back side. As indicated by reference numeral 91 in FIG. 7, it is preferable to place all the overlapping portions 70d in the range of 180 degrees on the back side in the circumferential direction. One example is shown in FIGS. The position of the overlapping portion 70d is shown by reference signs P1 to P5 in order from the innermost prepreg 71. Five overlapping portions 70d are evenly distributed at intervals of 45 degrees as shown by reference numerals P1 to P5 in a range of 180 degrees which is a half circumference on the back side. The positions are shifted in the circumferential direction so as not to overlap, that is, not to be located at the same place in the circumferential direction. In addition, regarding the inner four (symbols P1 to P4) among the total five overlapping parts 70d (symbols P1 to P5), the overlapping part 70d of the reinforcing fiber layers adjacent to each other is viewed from the front side in a cross-sectional view. The positions are shifted alternately with respect to the center line T extending in the vertical direction toward the back side. The outermost overlapping portion 70d (reference numeral P5) is located on the center line T in the vertical direction. Thus, the length of the prepregs 71, 72, 73, 74, and 75 in the longitudinal direction A and the position of the notch 60 are set so that the overlapping portion 70d of each layer is positioned at a predetermined position when wound around the mandrel. ing.

  The cylindrical hood 16 configured as described above has a total of five reinforcing fiber layers that are formed by overlapping both side edge portions 70c of the prepreg 70 to form a cylindrical shape. A thin prepreg can be used, and the mandrel can be wound easily and neatly as compared with a thick prepreg. Since the overlapping portion 70d of each layer is positioned at a location 90 other than the location where the leg holding portion 56 is formed in the circumferential direction, the overlapping portion is not attached to the leg holding portion 56 where a large force acts from the reel legs. 70d does not exist, and therefore the cylindrical hood 16 has high durability. In particular, since all the overlapping portions 70d are arranged in the range 91 of 180 degrees on the back side in the circumferential direction, it is easier to secure the strength. In addition, since the overlapping portions 70d of the respective layers are arranged so as to be displaced in the circumferential direction, the overlapping portions 70d of the respective layers are dispersed in the circumferential direction, and the overall thinning can be achieved. . In addition, stress concentration at specific locations in the circumferential direction can be dispersed. With the arrangement and the dispersive arrangement on the back side of the overlapping portion 70d, the cylindrical hood 16 can be made as thin as stainless steel, and the weight can be significantly reduced as compared with stainless steel. For example, the thickness can be reduced to a thickness of 0.5 mm and a weight of 1 g. This is about 1/4 of the weight made of stainless steel, and greatly contributes to further weight reduction of the reel seat 10 and hence the fishing rod. In addition, since the thickness is about 0.5 mm, the level difference between the reel sheet body 29 and the reel sheet 10 is minimal, and the reel sheet 10 is less uncomfortable and easy to grip, and the operability of the fishing rod is also improved. improves.

  In particular, since the overlapping portions 70d are arranged at intervals of 45 degrees in the range of the back side half circumference 91, the overlapping portions 70d are evenly distributed on the back side, and the overlapping is performed while effectively using the area on the back side. The mating portion 70d can be dispersed, and both thinning and securing of strength can be easily achieved. Moreover, since the overlapping portions 70d (reference numerals P1, P2, P3, P4) adjacent to each other on the inner side and the outer side with respect to the center line T extending in the vertical direction in the cross-sectional view of the cylindrical hood 16 are shifted in the left and right directions, The overlapping portions 70d adjacent inside and outside can be easily separated in the circumferential direction, and local thickening can be easily prevented. Further, the cylindrical hood 16 is not twisted in one direction in the circumferential direction, so that a stable shape can be secured and the strength can be easily secured.

  Further, since the V-shaped cutout portion 60 is formed at the other axial end portion 70b of the prepreg 70, it is possible to easily cope with the reduction of the circumferential length and to prevent the occurrence of wrinkles. In particular, by forming the notch portion 60 at a place where the leg holding portion 56 is formed, which is a place where wrinkles are likely to occur in the circumferential direction, the generation of wrinkles can be more reliably suppressed. Furthermore, the notches 60 are respectively formed at locations corresponding to the left and right side portions 56b of the leg holding portion 56 in the circumferential direction, so that the prepreg can be smoothly wound around the mandrel, and wrinkles are more likely to occur. It is further suppressed.

  Furthermore, since the prepregs 72, 73, 74 made of the laminated sheet 83 in which the longitudinal sheet 81 and the transverse sheet 82 are laminated are used as the main layer, the shape changes in two directions, the circumferential direction and the axial direction. The cylindrical hood 16 can be easily manufactured. That is, when the prepregs 72, 73, and 74 are wound around the mandrel, the lateral sheet 82 can prevent the reinforcing fibers of the longitudinal sheet 81 from shifting so as to open in the circumferential direction. Can be prevented by the vertical sheet 81. Further, since two or more reinforcing fiber layers formed from the prepregs 72, 73, and 74 of the vertical and horizontal bonded materials are provided, a thin vertical and horizontal bonded material (laminated sheet 83) can be used and smoothly wound. Can turn. Furthermore, since the prepreg 71 of the bias material is used, the reinforcing fiber of the bias material functions as a bracing to the prepregs 72, 73, and 74 of the vertical and horizontal bonded materials, and the reinforcing fibers in the vertical and horizontal directions in the vertical and horizontal bonded materials. Effectively prevent deformation.

  On the other hand, the tubular hood 16 can be made thinner by configuring the movable hood body from the tubular hood 16 and the connecting body 17. In addition, it is easy to change only the pattern and color of the cylindrical hood 16 while leaving the connecting body 17 as it is, and since the design prepreg 75 is used in the outermost layer in particular, the design prepreg 75 The pattern of the cylindrical hood 16 can be easily changed simply by changing the specification. And since the pad part 19 is arrange | positioned inside the leg holding | maintenance part 56, the other end part of a reel leg can be stably hold | maintained firmly with the pad part 19 which consists of synthetic resins, and a reel leg is directly a cylinder. Since it does not hit the leg holding part 56 of the hood 16, the leg holding part 56 of the cylindrical hood 16 can be prevented from being damaged. Further, since the locking projection 39 that locks in the circumferential groove 50 of the operation nut 14 is provided in the connecting body 17, it is not necessary to form the locking projection 39 on the cylindrical hood 16, and the cylindrical hood 16 is Can be thinned. In this way, the pad portion 19 and the locking projection 39 are integrally formed via the base ring portion 18 and configured as one member called the coupling body 17, so that the cylindrical hood 16 is relatively simple. Since the shape is sufficient and the post-processing is also minimal, the cylindrical hood 16 can be easily made strong and thin. On the other hand, the connection body 17 can be easily manufactured even if it has a complicated shape by forming from a synthetic resin by molding. Further, by providing the base ring portion 18, the key portions 20, 21, 22, and 23 can be easily provided not only at one location on the front side where the pad portion 19 is present but also at other locations, and reliably and smoothly. The movable hood body can be moved in the axial direction. Further, since the locking projections 39 and the locking projections 43 are formed at the tips of the key portions 20, 21, 22, and 23, the connection body 17 can be easily molded.

  In the present embodiment, the base ring portion 18 and the pad portion 19 are integrally formed, but they may be configured separately. Further, although the locking projections 39 are formed in total at four locations together with the key portions 20, 21, 22, and 23, the locking projections 39 may be formed at positions different from the key portions 20, 21, 22, and 23. Alternatively, the locking projection 39 may be formed over the entire circumference to be annular. When the locking projection 39 is formed in an annular shape, it is preferable to form slits at predetermined locations in the circumferential direction so as to be easily deformed in the radial direction when attached to the operation nut 14. Thus, the design of the connection body 17 can be variously changed.

  Also, various design changes can be made for the cylindrical hood 16 and the total number of reinforcing fiber layers is provided in the above-described embodiment. However, the number of layers is arbitrary, and it is sufficient that at least two layers are provided. . Although the specification of the prepreg to be used is also arbitrary, it is preferable to use a prepreg made of a vertically and horizontally bonded material. Moreover, it is preferable to use one prepreg made of a bias material and use one or more prepregs made of a longitudinal and lateral bonded material. The reinforcing fiber layer provided mainly for the design in the outermost layer may be omitted. Alternatively, for example, a prepreg made of a bias material may be used in the outermost layer. Furthermore, although two cutouts 60 are formed, only one cutout 60 may be formed, or this may be omitted depending on the shape or the like of the leg holding part 56 or may be replaced with the V-shaped cutout 60. Only cuts (slits) may be formed. As described above, the prepreg can be formed in various shapes.

  In the above embodiment, the fixed hood portion 12 is formed integrally with the reel sheet main body 29. However, the fixed hood may be formed separately from the reel seat main body 29. The cylindrical hood 16 having the above-described configuration may be used.

  In addition, although the reel sheet 10 for attaching a spinning reel was demonstrated, it is applicable also to the reel sheet 10 for attaching a biaxial reel.
