US 5,175,952 A · Fishing rod and method of manufacturing same

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. A polypropylene sheet is wound on the mandrel to form an intermediate swell, and then a prepreg is wound on the polypropylene sheet such that an outer surface thereof rearwardly of the intermediate swell extends parallel to the straight outer surface of the mandrel. The resulting product is baked, and thereafter the mandrel and the polypropylene sheet are removed to complete the inner rod section which is fitted in the outer rod section.

A fishing rod comprising:

a tubular outer rod section (2), and
a tubular inner rod section (3), said inner rod section being inserted into the outer rod section, and said inner rod section being retainable in pulled out and inserted positions relative to the outer rod section, and wherein the inner rod section includes:
(a) a first portion (T) having a front portion, a rear portion, and a tapered outer surface whose outer diameter increases gradually from the front portion toward the rear portion;
and
(b) a second portion (S) extending longitudinally from the rear portion of the first portion (T), said second portion having a front portion, a rear portion, and an outer surface, wherein the outer surface of the second portion is substantially cylindrical being of substantially constant diameter between the front and rear portions of the second portion, and wherein the thickness of the second portion increases from the front portion of the second portion toward the rear portion of the second portion;
and
wherein substantially the entire length of the second portion (S) is housed inside of the outer rod section (2) when the inner rod section (3) is in its inserted position relative to the outer rod section;
and
wherein substantially the entire length of the second portion (S) is located outside of the outer rod section (2) when the inner rod section (3) is in its pulled out position relative to the outer rod section.
