  • Patent number: 5769344
    Abstract: The present disclosure concerns a spinning reel for fishing which eliminates the accumulation of line twists in a fishline regardless of the line winding diameter on a spool. The spinning reel for fishing includes a rotor rotatably mounted to a reel main body, and the spool is supported on the reel main body through a spool shaft. Turning a manual handle causes the rotor to rotate around the spool. A line roller is supported on the rotor and guides the fishline onto the spool during winding. The line roller is oriented such that the diameter of a fishline guide portion of the line roller increases in the direction of rotor rotation during winding. A guide projection extending generally toward the longitudinal midpoint of the line roller contacts the fishline to ensure the fishline is maintained at a desired position with respect to the line roller during winding.

  • Patent number: 5730377
    Abstract: The invention concerns a spinning reel for fishing which is not affected by a diameter of a roll of a wound fishing line, and hence is able to avoid accumulation of twist of a fishing line and entanglement of a fishing line resulting from accumulation of twist of a fishing line, thereby enhancing the handling property of a spinning reel. In the spinning reel for fishing, a support member for supporting a line roller to a rotor is provided with a first control section for controlling a line path from a distal end of a fishing rod to the line roller, and with a second control section for controlling a line path from the line roller to the spool. The first control section is disposed closer to a direction of fishing line winding carried out by the rotor than the second control section. The line roller may be mounted at a fixed, oblique angle either within the support member or relative to a fishing line winding direction or rotor axis.

  • Patent number: 5690289
    Abstract: A handle mounting structure in a fishing reel, which spreads open and deforms a collar by means of the taper action of a tapered engaging surface formed in the end portion of a handle shaft to thereby be sure to prevent the handle shaft from being loosened and clattered in the rotational direction thereof. The handle mounting structure includes: a drive shaft having a drive gear and a through-hole; a handle shaft to which a handle is fixed and which is non-rotatably fitted into the through-hole of the drive shaft; a tapered engaging surface formed on an end portion of the handle shaft; a collar deformable radially outwardly and fitted into the through-hole of the drive shaft so that one end of the collar is confronted with the tapered engaging surface; and a threaded member engageable with the handle shaft.

  • Patent number: 5681001
    Abstract: A spinning reel for fishing with an improved apparatus for guiding a fishline to a spool, such that when a rotor 2 and bail support members A, B are rotated in the direction in which the fishline is wound up, a fishline 13 is guided by a fishline guide roller 5 and the tilted face 7d of an annular guide portion 7 or the tilted face 9d of an annular guide portion 9, or the tilted faces 7d, 9d of both annular guide portions 7 and 9 before being wound onto a spool 3. While the fishline guide roller 5 is rotated because of the tension in the fishline 13, it is then forced to shift in a direction opposite to a line slider 6. The guiding action of the tilted faces 7d, 9d of the annular guide portions 7, 9 further causes the fishline 13 to be wound on the spool 3 to become twisted in a direction opposite to the direction in which the fishline is played out, without being affected by the fishline winding diameter.

  • Patent number: 5678781
    Abstract: A rolling member fitted into a guide recess and capable of performing a wedge action on a collar of a rotary quill is held by an annular holder in such a manner that the longitudinal movement of the rolling member can be restricted and the outside of the annular holder is rotatably fitted with an annular outer frame for restricting the outward movement of the rolling member, thereby forming a brake main body. By rotating the annular holder by use of a rotation operation member provided in the annular holder, the rolling member is controlled such that it can be restricted and held at an operative position allowing the wedge action or at a non-operative position prohibiting the wedge action, thereby switching the rotary quill to a reversal preventive position or to a reversal allowable position. Also, the brake main body is constructed as detachable one unit.

  • Patent number: 5615843
    Abstract: A spinning reel for fishing includes a rotor rotatably fitted to a reel body, and a spool supported by the reel body via a spool shaft in such a manner that the spool is capable of a traverse motion in the axial direction of the spool shaft and that a fishing line is wound thereon when the rotor is rotated by a manually operated handle. The spinning reel for fishing is further includes a fishing-line entry restrainer for preventing the fishing line from being wound on the spool shaft. The fishing-line entry restrainer is movably fitted to the cylindrical portion of the rotor placed in the spool. A follow-up mechanism is provided for causing the fishing-line entry restrainer to move forward when the spool is moved in the same direction.

  • Patent number: 5564640
    Abstract: A drag device which does not require a large number of parts, is easy to assemble, is highly corrosion resistant and can keep its commercial value. Brake plates and a friction plate provided in the drag device are inserted into a central recessed portion formed in a spool. A pressure member is non-rotatably fitted to the outer periphery of a rotation preventive portion of a leading end small diameter portion formed in a spool shaft, while a nut mounted to an operation member is threadingly engaged with a threaded portion formed in the leading end portion of the small diameter portion. After the pressure member and operation member are assembled together, a removal preventive member is superimposingly assembled to a stepped portion provided in the operation member and an engaging portion is secured by means of the elastic deformation of a securing portion, so that the pressure member is secured to the operation member rotatably but unremovably.

  • Patent number: 5503343
    Abstract: An arrangement for a reverse rotation preventive device for a fishing reel. A hollow engagement member, which is a part of a rotor, is non-rotatively fitted on a drive shaft having an oblong cross-section. A bearing and a hollow collar are simply fitted on the drive shaft. The hollow collar and the hollow engagement member are formed with engagement portions through which they are non-rotatively coupled together. A one-way clutch is arranged so that an outer race member is fixed to a main body and a roller is located between the collar and the outer race member to provide a reverse rotation preventive function when the drive shaft is rotated reversely. By coupling the collar, which is formed into a simple configuration and contacts with the roller, to the engagement member non-rotatively fitted on the drive shaft, it is possible to maintain the dimensional accuracy and high-performance of the rolling-type one-way clutch utilizing wedge action.

  • Patent number: 5489069
    Abstract: A reverse rotation preventive mechanism includes an engagement toothed portion formed on the inside circumferential surface of a rotor of a spinning reel so as to minimize the quantity of the unavoidable reverse rotation of the rotor to quicken hooking of a fish. A V-shaped engagement member having an engagement portion and an operating portion is swingably supported at the front portion of the casing of the spinning reel. The operating portion is engaged with a control member fitted on and frictionally engaged with a rotary quill. When the quill is rotated forward to wind a fishline on the reel, the control member is swung by the quill to disengage the engagement portion from the engagement toothed portion to make no contact noise at the forward rotation of the rotor and apply no resistance to the forward rotation. When the quill is rotated backward or reversely to unwind the fishline form the reel, the control member is swung by the quill to engage the engagement portion with the engagement toothed portion.
