  • Patent number: 6269585
    Abstract: A fishing rod includes a tubular rod, an inner rod, and fishline guides. The inner rod has a fishline guiding passage therethrough, and is fitted in or detached from the tubular rod. The fishline guides project toward a center axis in the fishline guiding passage, and are fitted in or detached from the tubular rod. When the inner rod and the fishline guides are attached in the tubular rod, fishline is held by the fishline guides within the tubular rod, and it is drawn out or pulled back through an opening at the tip of the rod. When the inside of the rod is to be cleaned, the inner rod and the fishline guides are taken out of the tubular rod, and they are easily cleaned.

  • Patent number: 5934005
    Abstract: A pass-through fishing rod comprising a line support and retainers prevents a fishing line from contacting the inner surface of a rod or water adhering to the inner surface and enables the line to be drawn out and rolled up smoothly. The line support pitch of the line support supporting a fishing line is smaller than the retention pitch of the retainers for retaining the line support spaced from the inner surface of the rod.

  • Patent number: 5347743
    Abstract: A guide for use on a fishing rod includes a guide ring placed in contact with an outer surface of a rod stock for guiding a fishing line, and a holder for fixing the guide ring to the rod stock. The guide is manufactured by placing the guide ring in contact with an outer surface of the rod stock, arranging dies to surround the guide ring and rod stock, and injecting a plastic inside the dies, thereby forming the holder from the plastic. As an alternative to the use of dies, prepreg may be wound in a way to fasten the guide ring to the rod stock, and baked to harden, thereby forming the holder.

  • Patent number: 5194207
    Abstract: A fishing rod is manufactured by forming a tubular small diameter portion on an outer surface of a rod material. The small diameter portion is formed continuous with and between a pair of walls substantially perpendicular to an axis of the rod material. Then a seat base is formed by placing a pair of dies around the small diameter portion and injecting a heated thermoplastic resin into a cavity (inside space) defined by the dies.

  • Patent number: 4726139
    Abstract: A mounting structure for mounting on a fishing rod a fishing reel having a mounting leg. The mounting structure includes a reel seat including a seat body, a fixed holder integral with the seat body for receiving one end of the mounting leg, and a movable pusher receiving the other end of the mounting leg so that the fixed holder and movable pusher hold therebetween the mounting leg to be fixed on the seat body. The seat body is formed of a semicylindrical-shaped material. A pair of elastically deformable fitting parts elastically engaging the seat body with the fishing rod is provided integrally with the seat body. A prepreg formed of high strength fiber impregnated with synthetic resin is wound onto the fixed holder and fishing rod, thereby fixing the seat body to the fishing rod.
