  • 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: 5476231
    Abstract: The present disclosure concerns a simple structure for a fly type fishing reel to prevent the occurrence of noise caused by axial backlash between a shaft and a spool. A spool is rotatably supported on a shaft through at least one bearing, and a peripheral groove is formed on a fore end portion of the shaft. A cap is fixed to a center of the spool with a screw. An engaging knob plate to detachably engage the spool with the shaft is provided between the cap and the spool. A concave portion is formed approximately at a center of the reverse side of the cap for accommodating the fore end portion of the shaft, and a floating absorption member is inserted into and fixed in the concave portion. The floating absorption member may be made of felt, a resilient laminated member of rubber on which a metallic plate and a synthetic resin plate are stacked, or a leaf spring.

  • Patent number: 5195699
    Abstract: An improved spool of the type used in fishing reels facilitates removal of old line from the spool so that the time required to replace a worn line is reduced from nearly half an hour to just a few moments. The same improved spool also has utility in removing line from conventional spools. The improved spool is built in two parts that are detachably secured to one another and quickly releasable from one another. The central part of the spool has a hyperbolic contour which serves to wind the line into a compact coil so that the removed line is easily stored in a small space for subsequent recycling or appropriate disposal.
