  • Patent number: 5291683
    Abstract: A fishing rod has a seat base including a fixed hood formed integral therewith for engaging a forward leg of a fishing reel, and a movable hood mounted in the seat base to be movable axially thereof for engaging a rearward leg of the fishing reel. The seat base defines an opening edge of a space for accommodating the movable hood. This opening edge is inclined, in side view, with respect to an axis of the fishing rod. A rotatable adjusting element is mounted on the seat base for adjusting position of the movable hood axially of the fishing rod. A slide contact element is disposed at an end of the rotatable adjusting element remote from the movable hood for limiting movement of the rotatable adjusting element axially of the fishing rod 2. A fishing rod as claimed in claim 1, wherein said seat base includes a rotatable adjusting element relatively rotatably mounted thereon for adjusting position of said movable hood axially of the fishing rod.

  • Patent number: 5189824
    Abstract: A fishing rod includes a fixed hood formed on a rod body, a movable hood having an inner threaded portion engageable with a threaded portion of the rod body. The fixed hood and the movable hood together form a reel seat for supporting opposed ends of a foot of a reel. At an inner peripheral face of the movable hood where the one longitudinal end of the reel foot is engaged, there is formed a threaded guide groove having a pitch corresponding to a pitch of the inner threaded portion. And, a contact face is also defined in the inner peripheral face of the movable hood facing the fixed hood. The contact face comes into contact with a terminal edge of the reel foot in a direction substantially normal to an axis of the inner threaded portion.

  • Patent number: 5175952
    Abstract: A fishing rod includes an outer rod section, and an inner rod section inserted into the outer rod section for telescopic movement. The inner rod section is retainable in an extended position and a compressed position relative to the outer rod section. The inner rod section includes a tapered portion extending from an intermediate position to a tip end thereof and tapering toward the tip end, and a straight portion extending from the intermediate position to a rear end. Further, the inner rod section defines an inside wall becoming progressively thicker from the intermediate position to the rear end. The inner rod section is manufactured by using a mandrel having a tapered outer surface tapering from an intermediate position to a forward end, and a straight outer surface from the intermediate position to a rear end thereof.
