  • 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: 5231783
    Abstract: A method of making a pipe-like member such as a fishing rod and a golf club is disclosed. According to the method, a tape-like prepreg is formed by overlaying each other a first fiber layer comprised of fibers aligned along a longitudinal direction of the layer and a second fiber layer comprised of fibers aligned in a direction substantially normal to the fiber alignment direction of the first fiber layer. Then, the tape-like prepreg is wound about a mandrel with a turn of the prepreg being widthwise overlapped with an adjacent turn of the prepreg. Thereafter, the assembly is sintered.
