Abstract

A fishing rod is provided which is formed of a handle having a fishing reel mounting portion, a grip, and a rod body tapered toward its tip. The larger diameter side of the rod body includes a tubular fitting portion having a tapered portion increasing gradually in diameter at a rate of change larger than that of the rod body. The tubular fitting portion is fitted onto the outer periphery of the handle and is coupled integrally therewith. A manufacturing method is also provided for forming the rod body integrally with the tubular fitting portion.

Claims

1. A fishing rod comprising a handle having a reel mounting portion and a grip, a rod body, and a tubular fitting portion joining said rod body with said handle, said tubular fitting portion having a tapered portion at which said rod body is connected with said tubular fitting portion and a fitting portion which is in continuation of said tapered portion and is fitted onto said reel mounting portion of said handle, said fitting portion having a cutout portion at least a portion of its length exposing therethrough said reel mounting portion of said handle to the exterior.

2. A fishing rod according to claim 1, wherein said rod body comprises prepreg of high strength fibre permeated with synthetic resin, and said tubular fitting portion is in continuation of said rod body and is formed integrally with said pregreg forming said rod body.

3. A fishing rod according to claim 1, wherein said rod body comprises a first prepreg of high strength fibre permeated with synthetic resin, and said tubular fitting portion is in continuation of said rod body and comprises a second prepreg separate from said first prepreg, said second prepreg overlapping with a root end of said rod body, said tubular fitting portion being integral with said rod body comprising said first prepreg.

4. A fishing rod according to claim 3, wherein at least an outermost layer of said tubular fitting portion comprises a sheet comprising a first yarn group of high strength fibre arranged longitudinally and a second yarn group of high strength fibre arranged transversely relative to said first yarn group, said first and second yarn groups being overlapped with each other in relation of being crossed at right angles respectively and coupled with each other by use of weaving threads, said sheet being permeated with synthetic resin.

5. A fishing rod according to claim 1, wherein a connecting portion between said rod body and said tubular fitting portion is larger in thickness than said rod body, said tubular fitting portion decreasing gradually in thickness rearwardly from said connecting portion.

6. A fishing rod according to claim 1, wherein said handle is provided at a portion thereof fitted into said tubular fitting portion with a plurality of recesses.

7. A fishing rod according to claim 1, wherein said fitting portion includes a uniform diameter portion.

8. A fishing rod according to claim 1, wherein said rod body is tapered and hollow and said tapered portion has a diameter which expands at a greater rate of change than a rate of change of a diameter of said rod body, said fitting portion being in continuation of a largest diameter portion of said tapered portion.

9. A fishing rod according to claim 1, wherein said tubular fitting portion is in continuation of said rod body.

11. A fishing rod manufacturing method according to claim 7, further comprising forming a bridge member for covering a joint between said rod body and said second mandrel for molding said tubular fitting portion, mounting said bridge member onto said joint, and winding said second prepreg around said second mandrel.

12. A fishing rod manufacturing method according to claim 11, wherein said bridge member comprises prepreg of a boron fibre sheet permeated with synthetic resin.

13. A fishing rod manufacturing method according to claim 7, further comprising prior to winding said second prepreg around said second mandrel, winding a reinforcing tape smaller in width and of high strength fibre permeated with synthetic resin spirally around said second mandrel.

14. A fishing rod manufacturing method according to claim 7, wherein said rod body is formed to be tapered and hollow and said tapered portion is formed to have a diameter which expands at a greater rate of change than a rate of change of a diameter of said rod body, said fitting portion being in continuation of a largest diameter portion of said tapered portion and said tubular fitting portion being in continuation of said rod body.

10. A manufacturing method for forming a fishing rod including a handle having a reel mounting portion and a grip, a rod body and a tubular fitting portion joining said rod body with said handle and including a tapered portion at which said tubular fitting portion is connected with said rod body and a fitting portion in continuation of said tapered portion and fitted onto said reel mounting portion, said method comprising:

(a) winding a first prepreg of a high strength fibre sheet permeated with synthetic resin around a first tapered mandrel and then baking said wound prepreg sheet under pressure to preform a hollow rod body;

(b) providing a fitting member on a second mandrel, said second mandrel being for molding said tubular fitting portion of said rod body, providing said fitting member with an outer peripheral surface to be fitted into an inner surface of an end of said rod body and a locking means at said outer peripheral surface;

(c) fitting said outer peripheral surface of said fitting member into said end of said rod body to be not-rotatable relative thereto; and

(d) winding a second prepreg of high strength fibre sheet permeated with synthetic resin around said second mandrel to overlap an end portion of said second pregreg with an outer peripheral surface at said end of said rod body and baking said wound second prepreg under pressure to couple said tubular fitting portion integrally with said rod body.
