Description

  The present invention relates to a reel seat for fixing a leg portion of a fishing reel and a fishing rod provided with the reel seat. More specifically, the present invention relates to a reel seat that fixes a leg portion of a fishing reel by moving a movable hood of the reel seat with a double nut, and a fishing rod including the reel seat.

  The fishing reel is fixed to a fishing rod via a reel sheet. For example, Japanese Patent Laid-Open No. 2009-65868 (Patent Document 1) discloses a reel seat portion, a fixed hood attached to one end portion of the reel seat portion, and a fishing rod at the other end portion of the reel seat portion. There is disclosed a fishing rod reel sheet including a movable hood attached to be movable in the axial direction. The reel seat is provided with a fastening nut adjacent to the movable hood. By tightening the fastening nut, the movable hood can be moved in a direction approaching the fixed hood. In this way, the legs of the fishing reel are fixed between the movable hood and the fixed hood.

  Since vibration is applied to the movable hood through the legs of the fishing reel, there is a known problem that the fastening nut adjacent to the movable hood is easily loosened. In order to cope with this problem, it has been proposed to tighten the movable hood using a double nut.

  However, even if a double nut is used, the occurrence of loosening due to vibration cannot be completely prevented. Therefore, an improvement for preventing the loosening of the double nut has been proposed. For example, in Japanese Utility Model Publication No. 49-16467 (Patent Document 2) and Japanese Unexamined Patent Application Publication No. 2010-99907 (Patent Document 3), a locking ring whose rotation is restricted between two nuts constituting a double nut is disclosed. Proposed to provide.

JP 2009-65868 A Japanese Utility Model Publication No. 49-16467 JP 2010-99907 A

  As pointed out in Patent Document 3, in order to shorten the axial length of the reel sheet, the locking ring is formed so that the axial length is as short as possible. That is, the locking ring is formed to be narrower than the nut constituting the double nut. Therefore, the locking ring is easily inclined with respect to the axial direction of the housing.

  When tightening the double nut, a large stress acts on the locking ring. Since the locking ring is formed narrow, it is easily broken when a large stress is applied. In particular, when the locking ring is inclined with respect to the axial direction, stress is likely to concentrate at a specific location, so that breakage is likely to occur at the location where the stress is concentrated.

  One of the objects of the present invention is to make the locking member of the double nut for the reel sheet difficult to break. Other objects of the present invention will become apparent by referring to the entire specification.

  A reel seat according to an embodiment of the present invention includes a cylindrical reel seat body that is externally mounted on a housing and configured to receive a first leg of a fishing reel, and a second reel reel of the fishing reel. A movable hood for receiving a leg; and a nut mechanism for moving the movable hood along an axial direction of the housing. A male screw is formed on the outer periphery of the reel sheet body. In an embodiment of the present invention, the nut mechanism is a so-called double nut. The nut mechanism includes a first nut that is screwed to the male screw of the reel sheet body, a second nut that is screwed to the male screw of the reel sheet body, and the first nut and the second nut. And a sleeve that is non-rotatably mounted around the housing. The sleeve has a slit.

  According to this embodiment, the loosening of the nut mechanism is suppressed by the sleeve. Since the sleeve is disposed between the first nut and the second nut, a large stress acts on the sleeve when the nut mechanism is fastened. Since the sleeve is cut, the sleeve is more easily deformed than a conventional ring-shaped locking ring. Therefore, even if a large stress is applied, the sleeve is not easily broken.

  In the reel sheet according to an embodiment of the present invention, a protrusion extending along the axial direction of the casing is formed on the inner peripheral surface of the sleeve, and the axial direction of the casing is formed on the outer peripheral surface of the reel sheet main body. A groove extending along the projection and receiving the protrusion is formed. The protrusion may be formed on the inner circumferential surface of the sleeve on the side opposite to the slit.

  According to the embodiment, the protrusions formed on the inner peripheral surface of the sleeve can reliably regulate the rotation of the sleeve around the casing. When the sleeve is deformed, the stress tends to concentrate at a position opposite to the slit. By providing the projection on the opposite side of the sleeve slit (for example, a position rotated 180 ° from the slit in the circumferential direction of the sleeve), it is possible to reinforce a portion of the sleeve where stress is likely to concentrate.

  In the reel sheet according to an embodiment of the present invention, the sleeve is configured so that it cannot be attached to and detached from the reel sheet body from a direction perpendicular to the axial direction of the housing. In the reel sheet according to an embodiment of the present invention, the sleeve is configured to be deformable in a range in which the width of the cut is smaller than the diameter of the reel sheet main body. According to these embodiments, it is possible to prevent inadvertent dropping of the sleeve.

  The reel sheet according to an embodiment of the present invention further includes a ring that is sheathed on the sleeve. The ring is configured to cover the slit of the sleeve when it is sheathed on the sleeve. According to the embodiment, the slit formed in the sleeve is not exposed on the reel sheet surface. The reel seat has an outer surface with a smooth curve in consideration of the grip feeling by the angler. If the cut is exposed on the reel sheet surface, the angler's finger touches the cut, which may cause discomfort to the angler. According to the above embodiment, since the cutting is not exposed on the surface of the reel sheet, it is possible to improve the grip comfort of the angler.

  A fishing rod according to an embodiment of the present invention includes any of the reel sheets described above.

  According to the embodiment of the present invention, the locking member (sleeve) of the double nut for the reel sheet is not easily broken. Therefore, a double nut having a locking member that is not easily broken can be used for the fishing reel seat.

  Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, common components are denoted by common reference numerals. It should also be noted that the drawings are not necessarily drawn to scale for convenience of explanation.

  First, a reel seat and a fishing rod including the reel seat according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a side view showing a fishing rod according to an embodiment of the present invention. As shown in the figure, a fishing rod according to an embodiment of the present invention includes an elongated cylindrical rod body 10. The housing 10 includes a reel sheet 30, a front grip 32, a rear grip 34, and a bottom plug 36. Various types of fishing reels 40 are mounted on the reel seat 30. A plurality of guides G for guiding the fishing line from the fishing reel 40 to the tip are attached to the housing 10.

  The fishing reel 40 is attached to the reel seat 10 via its leg portion 41. The leg portion 41 includes a support leg 42 extending from a reel body having a spool and a handle, a front leg 43 extending forward from the lower end of the support leg 42, and a rear leg 44 extending rearward from the lower end of the support leg 42. Have. The fishing reel 40 is not limited to a specific configuration as long as it can be mounted on the reel seat 10. In the present invention, for example, various reels such as a spinning reel, a double bearing type reel, and a single bearing type reel can be used as the fishing reel 40.

  In one embodiment of the present invention, the reel sheet 30 includes a reel sheet main body 20, a rear hood 22, a front hood 24, and a nut mechanism 25. The reel sheet body 20 is formed in a hollow cylindrical shape. The reel sheet body 20 is fixed to the outside of the housing 10 by adhesion or the like. A male screw 20N into which the components of the nut mechanism 25 are screwed is formed at the front part of the outer periphery of the reel seat body 20. On the outer surface of the reel sheet main body 20, a groove 20a extending substantially over the entire length in the axial direction is formed. As will be described later, the groove 20 a accommodates a protrusion formed on the inner peripheral surface of the front hood 24 and a protrusion formed on the inner peripheral surface of the sleeve 28. The reel seat body 20 is provided with a mounting surface 20S on which the front legs 43 and the rear legs 44 of the fishing reel 40 are mounted. The placement surface 20S has a planar shape so that the front legs 43 and the rear legs 44 can be placed stably.

  The rear hood 22 is provided at the rear part of the reel seat body 20. The rear hood 22 may be formed integrally with the reel seat body 20. The rear hood 22 may be formed separately from the reel seat body 20. In this case, the rear hood 22 is fixed to the reel sheet main body 20 by adhesion or the like. The rear hood 22 is configured and arranged so as not to move with respect to the reel seat body 20. In this sense, the rear hood 22 may be referred to as a fixed hood. The rear hood 22 is formed with a receiving port 22F that receives the rear leg 44 of the fishing reel 40.

  The front hood 24 is formed in a substantially cylindrical shape. The front hood 24 is configured separately from the rear hood 22. The front hood 24 is formed to have an inner diameter slightly larger than the outer diameter of the reel seat body 20. The front hood 24 is disposed on the outer peripheral surface of the reel seat body 20 at a position spaced apart from the rear hood 22 in the axial direction by a predetermined distance. The front hood 24 is formed with a receiving port 24F that receives the front leg 43 of the fishing reel 40. The inner peripheral surface of the front hood 24 has a protrusion 24 a that extends in the axial direction of the flange member in a state of being mounted on the casing 10. The front hood 24 is mounted on the reel sheet main body 20 so that the protrusion 24a engages with the groove 20a of the reel sheet main body 20 described above. When the protrusion 24a is engaged with the groove 20a, the front hood 24 can be freely moved in the axial direction while the rotation of the reel seat body 20 in the circumferential direction is restricted. Focusing on the fact that this movement in the axial direction is possible, the front hood 24 may be referred to as a movable hood or a movable hood.

  A nut mechanism 25 is provided in front of the front hood 24. The nut mechanism 25 is a double nut having two nuts. In the illustrated embodiment, the nut mechanism 25 includes a first nut 26 disposed adjacent to the front of the front hood 24, a second nut 27 disposed forward of the first nut 26, A loosening prevention sleeve 28 disposed between the first nut 26 and the second nut 27.

  The first nut 26 is configured to have an inner diameter slightly larger than the outer diameter of the reel sheet main body 20. A female screw 26 a is formed on the inner surface of the first nut 26. The first nut 26 is configured to be screwed with the male screw 20N of the reel seat body 20 via the female screw 26a.

  The second nut 27 is configured to have an inner diameter slightly larger than the outer diameter of the reel sheet main body 20. A female screw 27 a is formed on the inner surface of the second nut 27. The second nut 27 is configured to be screwed with the male screw 20N of the reel seat body 20 via the female screw 27a.

  The sleeve 28 is formed in a substantially cylindrical shape. In one embodiment, the sleeve 28 is formed narrow. Specifically, the length of the sleeve 28 in the axial direction of the housing 10 is shorter than both the length of the first nut 26 in the axial direction and the length of the second nut 27 in the axial direction. Formed as follows. In one embodiment, the sleeve 28 has an axial length that is half of the axial length of the first nut 26 and half the axial length of the second nut 27. It is formed to be shorter.

  On the inner peripheral surface of the sleeve 28, a protrusion 28 a is formed that extends in the axial direction of the housing 10 while being attached to the housing 10. The sleeve 28 is attached to the reel sheet main body 20 so that the protrusion 28a engages with the groove 20a of the reel sheet main body 20 described above. When the protrusion 28a is engaged with the groove 20a, the sleeve 28 is restricted from rotating in the circumferential direction of the reel sheet main body 20, but can freely move in the axial direction.

  The sleeve 28 is formed with a cut 28b. The slit 28b is formed so as to penetrate the inner peripheral surface and the outer peripheral surface of the sleeve 28. Further, the cut 28b is formed so as to penetrate the front end and the rear end of the sleeve 28. In one embodiment, the cut 28b is formed on the opposite side of the protrusion 28a (a position rotated about 180 ° or just 180 ° from the protrusion 28a). When the stress is applied to the sleeve 28 by the slit 28b, the sleeve 28 is expanded in the direction of increasing the diameter (direction of arrow a in FIG. 4) or in the direction of decreasing the diameter (direction of arrow b in FIG. 4). It can be elastically deformed.

  The slit 28 b is configured to have such a width that the sleeve 28 cannot be attached to and detached from the reel sheet main body 20 from a direction perpendicular to the axial direction of the housing 10. Specifically, the slit 28b is such that the width of the slit 28b does not become larger than the outer diameter (diameter) of the reel sheet main body 20 even when the sleeve 28 is deformed in the diameter-expanding direction (the direction of arrow a). It is formed. That is, the sleeve 28 can be deformed in a range where the width of the cut 28 b is smaller than the diameter of the reel sheet main body 20.

  The reel seat body 20, the front hood 24, the first nut 26, the second nut 27, and the sleeve 28 are typically formed by injection molding from a hard synthetic resin member such as ABS resin, nylon, or polyethylene terephthalate. . The material, manufacturing method, shape, and the like of the front hood 24 and the rear hood 22 are not limited to those specified in the present specification, and various modifications may be made to the embodiments exemplified herein. For example, the reel seat body 20, the front hood 24, the first nut 26, the second nut 27, and a part of the sleeve 28 are made of a metal such as aluminum, SUS, titanium, or a combination of these metals and a synthetic resin. It can be composed of a composite material.

  Before the fishing reel 40 is mounted, the first nut 26 and the second nut 27 are sufficiently loosened so that a sufficient space is ensured between the rear hood 22 and the rear reel 22. When mounting the fishing reel 40, first, the tip of the rear leg 44 of the fishing reel 40 is inserted into the receiving port 22 </ b> F of the rear hood 22. Subsequently, the first nut 26 is rotated in the fastening direction so that the front end of the front leg 8 of the fishing reel 40 is inserted into the receiving port 24F of the front hood 24. Accordingly, the first nut 26 moves together with the front hood 24 in a direction approaching the rear hood 22. In this manner, the front leg 43 and the rear leg 44 of the fishing reel 40 can be accommodated in the front hood 24 and the rear hood 22, respectively.

  Next, the sleeve 28 is moved toward the hand side along the housing 10 until it contacts the first nut 26. Subsequently, the second nut 27 is rotated in the fastening direction. Thereby, the 2nd nut 27 moves to the hand side (namely, the direction approaching the front hood 24 and the back hood 22). The sleeve 28 is pressed against the front end of the first nut 26 by sufficiently rotating the second nut 27 in the fastening direction. Thus, even if a force in the loosening direction acts on the first nut 26, the frictional force between the first nut 26 and the sleeve 28 prevents the rotation of the first nut 26 in the loosening direction. Is done.

  According to the embodiment described above, the looseness of the movable hood 24 and the nut mechanism 25 is suppressed by the sleeve 28. Further, since the sleeve 28 has the cut 28b, it is more easily elastically deformed than the conventional locking ring having a ring shape. Therefore, even if a large stress acts on the sleeve 28, the sleeve 28 is not easily broken. By forming the cut 28b, the stress at the time of deformation is easily concentrated on the opposite side of the sleeve 28 from the cut 28b. By providing the projection 28a on the inner peripheral surface of the sleeve 28 on the opposite side to the slit 28b, a portion where this stress tends to concentrate can be reinforced.

  FIG. 5 is a cross-sectional view showing a ring provided on a reel sheet according to another embodiment of the present invention. As shown in FIG. 5, in the reel sheet, a ring 38 is mounted on the sleeve 28. The ring 38 is configured to have an inner diameter that is slightly larger than the outer diameter of the sleeve 28. The ring 38 is fitted into the sleeve 28 from the outside so that the inner peripheral surface thereof is in contact with the outer peripheral surface of the sleeve 28. The ring 38 is formed such that its axial length is substantially the same as the axial length of the sleeve 28. The ring 38 is disposed so as to cover the sleeve 28 so that the sleeve 28 is not exposed on the surface of the reel sheet main body 10.

  According to the embodiment of FIG. 5, it is possible to prevent the slit 28 b of the sleeve 28 from being exposed on the surface of the reel sheet 10. If the cut 28b is exposed on the surface of the reel sheet 10, the angler's grip comfort will be adversely affected. Since the cut 28b is not exposed on the surface of the reel sheet 10 by the ring 38, according to the embodiment of FIG. 5, the gripping feeling of the angler can be improved.

  The dimensions, materials, shapes, and arrangements of each component described herein are not limited to those explicitly described in the embodiments, but rather are any dimensions that can be included within the scope of the present invention, Each component can be modified to have material, shape, and arrangement. In addition, components other than those explicitly described in the present specification can be added to the described embodiments, and some of the components described in the embodiments can be omitted.

  For example, in the illustrated embodiment, the rear hood 22 is movable with respect to the housing 10 and the front hood 24 is fixed to the housing 10, but the front hood 24 is movable with respect to the housing 10 and the rear hood. You may comprise 22 so that the movement with respect to the housing 10 is possible.
