Description

  The present invention relates to a fishing rod, and more particularly to a fishing rod having a reel leg fixing device to which a reel is mounted.

  Conventionally, as a fishing rod on which a reel can be mounted, for example, as disclosed in Patent Document 1, a reel leg fixing device configured in a cylindrical shape is externally fitted to an outer peripheral surface of a main rod configured as a tubular body. The configuration is known. This reel leg fixing device is provided with a reel leg mounting part for mounting the leg part of the reel and a pair of hood parts provided on both sides in the axial direction of the reel leg mounting part for fixing the reel leg. .

One of the pair of hood portions is fixed to the main body of the reel leg fixing device (fixed hood), and the other is provided on the main body so that it can slide in the axial direction (moving hood), for example, screwed to the main body By rotating the rotating member, the moving hood can be moved closer to or away from the fixed hood, and the reel can be mounted or removed.

  Usually, since the reel leg fixing device as described above is a portion on which a reel on which a large load acts is mounted, the main body is made of a hard synthetic resin member such as nylon or ABS, or a metal such as aluminum, SUS or titanium. These are integrally formed by, for example, applying an adhesive to the outer peripheral surface of the main shaft, and then being externally fitted to be fixed integrally to the main shaft. On the other hand, since the marshall is generally configured as a tubular body made of reinforced fiber resin, the reel leg fixing device has a higher bending rigidity and is less likely to bend than the marshall.

  For this reason, when the main rod is bent, such as when a large load is applied to the fishing rod, or when the main rod is pressed against the body and a large shackle operation is performed, the main body of the reel leg fixing device may not follow the deflection of the main rod. . That is, when the main shaft is bent, the main body of the cylindrical reel leg fixing device that is externally fitted to the main rod cannot follow the bending, so that a force that is expanded elliptically in the end region acts, In particular, stress concentration occurs in the main bar at the bending side (lower surface side) portion of the end portion of the main body.

  As a result, in the region corresponding to the end portion of the main body of the reel leg fixing device (end edge position of the main body), the durability is lowered, and there is a possibility that trouble may occur during actual fishing.

  The present invention has been made paying attention to the above-described problems, and a fishing rod capable of suppressing stress concentration with the reel leg fixing device even when the main rod portion is bent during actual fishing. The purpose is to provide.

  In order to achieve the above-described object, a fishing rod according to the present invention has a pair of fixings for fixing a reel leg mounting portion on which a fishing reel can be mounted and a reel leg mounted on the reel leg mounting portion. A cylindrical reel leg fixing device that is externally fitted to the main frame, and the main body of the reel leg fixing device has a body within a predetermined range from the end edge. Forming a low-rigidity region having a lower bending rigidity than that of the main body, and providing a flexible member having flexibility as compared with the main body on the low-rigidity region and / or the surface of the base adjacent to the low-rigidity region. It is characterized by being attached.

  In the above configuration, even if there is a difference in bending rigidity between the main shaft and the main body of the reel leg fixing device, a low rigidity region is formed within a predetermined range of the end portion of the main body of the reel leg fixing device. For this reason, when a load is applied to the main bar and bending occurs, the low rigidity region can follow the bending of the main bar. For this reason, it becomes possible to relieve the stress concentration that tends to occur at the end portion of the reel leg fixing device, and it is possible to suppress breakage and damage. Further, such a low-rigidity region is covered with a flexible member, and the flexible member is applied to the surface of the main bar adjacent to the low-rigidity region, so that stress concentration received from the edge portion of the main body is reduced. It can be dispersed and more effectively relaxed. In addition, about a flexible member, the structure which adheres only a low-rigidity area | region, the structure which adhere | attaches only the surface of the main fence adjacent to a low-rigidity area | region, or the structure which adheres both may be sufficient.

  According to the present invention, it is possible to obtain a fishing rod capable of suppressing stress concentration with the reel leg fixing device even when the main rod portion is bent during actual fishing.

  Hereinafter, embodiments of a fishing rod according to the present invention will be specifically described with reference to FIGS. 1 to 3. In these drawings, FIG. 1 is a diagram showing the overall configuration of a fishing rod, FIG. 2 is a longitudinal sectional view showing a reel leg fixing device portion, and FIG. 3 is an enlarged view of an end portion of the reel leg fixing device. (A) is a longitudinal sectional view, and (b) is a view seen from the axial direction.

  The fishing rod 1 according to the present embodiment includes a main rod 3 equipped with a cylindrical reel leg fixing device 10 that allows a fishing reel 50 to be attached and detached, and a leading rod 4 joined to the main rod 3. It is configured as a two-piece joint provided. In this case, the joining of the two flange members may be configured as a swing-out type, or may be configured as a side-by-side type. Moreover, the joining number of each eaves member is arbitrary, and the structure of the eaves member may be configured in a tubular body or may be configured in a solid shape. Further, as a material constituting the eaves member, for example, a prepreg sheet in which a reinforcing fiber is impregnated with a synthetic resin can be used.

  The rod member (tip rod 4) is provided with a plurality of fishing line guides (outer guides) 5 so as to guide the fishing line fed from the fishing reel 50 mounted on the reel leg fixing device 10. It has become. Further, grips 30 and 31 are provided on the front arm 3 before and after the reel leg fixing device 10 as necessary. Such a grip is constituted by, for example, a member (urethane resin, thermoplastic elastomer, cork, urethane foaming member, etc.) that is more flexible than the hardness of the main body 14 of the reel leg fixing device 10, It is attached to the outer periphery of the main fence 3.

  The reel leg fixing device 10 includes a reel leg mounting part 11 on which a leg part of a fishing reel 50 is placed, and a pair of hood parts 12a that are disposed opposite to each other and have openings for receiving the reel legs. , 12b. Since the main body 14 is a portion for firmly fixing a fishing reel to which a large load acts, it is integrally formed of, for example, a hard synthetic resin member such as nylon or ABS, or a metal such as aluminum, SUS, or titanium. In this case, the adhesive is applied to the outer peripheral surface of the main bar 3 and then fixed to the main bar 3 by being inserted.

  Of the pair of hood portions, the tip side hood portion 12a is configured as a moving hood, and the rear side hood portion 12b is configured as a fixed hood (hereinafter referred to as the moving hood 12a and the fixed hood 12b). As is well known, such a reel leg fixing device 10 rotates the rotation operation portion 16 with respect to the male screw portion 16a engraved on the outer peripheral surface of the main body 14, thereby the moving hood 12a is fixed to the fixed hood 12b. The fishing reel 50 is fastened and fixed in the axial direction so that it can be fixed and removed.

  The end portion of the main body 14 is formed with a low rigidity region 15 in which a predetermined range from the end edge 14a is lower than the bending rigidity of the main body 14 itself. This low-rigidity region 15 is a portion that exhibits an action that does not cause stress concentration on the main shaft 3 or relaxes stress concentration when the main shaft 3 is bent. The end portion of the main body 14 is provided at the rear end portion of the fixed hood 12b having a large thickness and high bending rigidity.

  Specifically, the low-rigidity region 15 is configured by thinning a predetermined range from an edge 14a on the rear side of the fixed hood 12b provided on the rear side of the main body 14 (a thin-thick portion is denoted by a reference numeral). 15a). In this case, as for the thickness of the thin-walled portion 15a, problems such as cracking occur if it is too thin, and if it is too thick, the bending rigidity increases and the tendency to cause stress concentration on the main bar 3 increases. It is preferable to set in the range of 20% to 50% of the wall thickness T at the rear edge of the fixed hood 12b.

  In addition, if the region where the thin-walled portion 15a is formed, that is, the region where the low-rigidity region 15 is formed (indicated by reference numeral L1 in FIG. 3) is too short from the edge 14a, a sufficient stress concentration relaxation effect is obtained. Therefore, the region L forming the low-rigidity region is preferably set to about 5 to 10 mm.

  Thus, by forming the low rigidity region 15 in the main body 14 of the reel leg fixing device 10, when a large load is applied to the main shaft 3 and bending occurs, the portion of the low rigidity region 15 has a bending rigidity. Since it is low, it becomes possible to follow the bending of the main bar 3, and as a result, the stress concentration on the main bar 3 is mitigated, and breakage and damage of the main bar 3 can be prevented. It becomes.

  Further, a cylindrical flexible member 18 made of a material having flexibility compared to the main body 14, for example, rubber, elastomer, EVA, cork or the like, is attached to the low-rigidity region 15. Yes.

  As shown in FIG. 2, such a flexible member 18 includes not only the low-rigidity region 15 formed in the main body 14, but also the rear side of the low-rigidity region 15 in the vicinity of the low-rigidity region 15. The surface portion is applied.

  In this way, by arranging the flexible member 18 so as to cover the low-rigidity region 15 and the surface portion of the main fence 3 adjacent to the low-rigidity region 15, the region L shown in FIG. It can be. That is, when the main bar 3 is bent, the portion where the bending stress first acts is the flexible member 18, so that the stress concentration applied from the edge of the main body 14 can be dispersed. The stress concentration acting on 3 can be relaxed more effectively. In addition, about 8-20 mm should just be installed about the stress concentration relaxation area | region L formed with the low rigidity area | region 15 by attaching the flexible member 18. FIG.

  The flexible member 18 described above may be configured to cover the surface area of the fixed hood 12b as shown in FIG.

  This is because, depending on the angler, the surface area of the fixed hood 12b may rest on the thumb of the hand when holding and holding the main rod 3 as shown in FIG. For example, after pressing the clutch plate of the fishing reel 50 with the thumb, the thumb is placed as it is by a series of operations, or when the hand is small like a woman or a child, Since the thumb may be placed on this portion, this portion is also attached with the flexible member 18, so that the placed thumb is less likely to slip, and the gripping and holding properties can be improved.

  Of course, as shown in FIG. 5, for example, the above-described flexible member 18 covers the surface portion of the base rod 3 in the vicinity of the low-rigidity region 15 and the rear side thereof without covering the surface of the fixed hood 12b. Such a configuration may be adopted. Alternatively, the flexible member 18 may be configured to be covered so as to cover only the low-rigidity region 15, or may be configured to be covered so as to cover only the main fence surface region adjacent to the low-rigidity region 15. There may be. In the former configuration, the low-rigidity region 15 is concealed so that the appearance can be improved. In the latter configuration, the stress concentration can be reduced by the flexible member.

  In a fishing rod equipped with the reel leg fixing device 10 configured as described above, when a large load is applied to the main rod 3 and bending occurs, the portion of the low rigidity region 15 has low bending rigidity. It becomes possible to follow the bending of the main bar 3, the stress concentration on the main bar 3 is mitigated, and breakage and damage of the main bar 3 can be prevented. In addition, since the flexible member 18 covers the low-rigidity region 15 and the surface of the rear armor 3 on the rear side, the stress concentration can be more effectively distributed, and the low-rigidity region 15 is reduced. Since it is not exposed, the appearance can be improved.

  In particular, in the present embodiment, the low rigidity region 15 is formed in the rear end region of the fixed hood 12b where the thickness is thick and the bending rigidity is high, so that the stress concentration on the main bar 3 is more effectively suppressed. It becomes possible to do.

  In the above-described embodiment, the low-rigidity region 15 is configured to reduce the bending rigidity by forming the thin-walled portion 15a at the end, but the configuration of the low-rigidity region 15 can be appropriately modified. It is.

  For example, it is possible to reduce the bending rigidity of the end region of the main body 14 by forming notches at predetermined intervals along the circumferential direction in a region within a predetermined range from the end edge 14a. Specifically, as shown in FIGS. 6A and 6B, the notch portion has a predetermined length from the end edge 14a toward the fixed hood 12b (preferably formed within the range of L1 described above). The slit 15b to be cut is formed at predetermined intervals along the circumferential direction, or, as shown in FIGS. 7A and 7B, the end region (within the range of L1 described above). May be formed at predetermined intervals along the circumferential direction.

  By forming such notches 15b and 15c, it is possible to reduce the bending rigidity of the end region, and the same effect as the above-described embodiment can be obtained. Such a notch may be formed in a thin-walled portion as described above, or as shown in FIGS. 6 and 7, without forming the thin-walled portion, It may be formed in the end region.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible. About the above-mentioned low-rigidity area | region 15, you may form in the edge part by the side of the movement hood 12a. In addition, the low-rigidity region 15 is not formed over the entire circumferential direction of the end portion of the main body 14, but when the main bar 3 is bent, the upper and lower portions of the main body 14 that are the portions where the bending stress is concentrated most. You may form only in a position.
