Abstract

Abstract The disclosure relates to a fishing rod formed from one or more lengths of rod material each length of which has a polygonal cross-section such as a hexagon or pentagon. Each length is formed from a number of triangular section elements having a base part of a fibre reinforced plastics and an apex part of a rigid plastics foam. The triangular section elements are bonded together with the base parts forming the outer wall of the section and the apex parts forming an inner core to resist collapse of the section when it is heavily bowed.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 86 words
Rod material for a fishing rod comprising an elongate member having a polygonal cross-section formed from a plurality of generally triangular section elements each having a base part of fibre-reinforced plastics and an apex part of filler material bonded to the base, the triangular section elements being bonded together with their bases forming an outer wall of the rod of polygonal form and their apex parts forming a core within the outer wall to support the rod material against collapse when the rod material is bowed.
Claim 2
Dependent Claim 86 words
Rod material for a fishing rod comprising an elongate member having a polygonal cross-section formed from a plurality of generally triangular section elements each having a base part of fibre-reinforced plastics and an apex part of filler material bonded to the base, the triangular section elements being bonded together with their bases forming an outer wall of the rod of polygonal form and their apex parts forming a core within the outer wall to support the rod material against collapse when the rod material is bowed.
Claim 3
Dependent Claim 68 words
Rod material as claimed in claim 1 wherein the triangular section elements are tapered from end-to-end and the member is formed from said tapered elements with the larger section ends of the elements all at one end of the member and the smaller section ends of the elements all at the other end of the member whereby the member is tapered from one end to the other end.
Claim 4
Dependent Claim 52 words
Rod material as claimed in claim 1 wherein the polygonal cross-section is so formed that the bending stiffness of the member in one plane is less than the bending stiffness in the transverse plane so that the rod member tends to bend more in that plane as opposed to any other plane.
Claim 5
Dependent Claim 36 words
Rod material as claimed in claim 3 wherein the bending stiffness of the rod material is reduced in said one plane by varying the stiffness of the elements of the rod member around the polygonal cross-section.
Claim 6
Dependent Claim 40 words
Rod material as claimed in claim 3 wherein the bending stiffness of the rod is reduced in said one plane by reducing the depth of the polygonal cross-section in that plane as compared with the depth of the polygonal cross-section.
Claim 7
Dependent Claim 20 words
Rod material as claimed in claim 1 wherein the apex parts of the elements are formed from expanded plastics material.
Claim 8
Dependent Claim 19 words
Rod material as claimed in claim 6 wherein the apex parts of the elements are formed from expanded polyurethane.
Claim 9
Dependent Claim 19 words
Rod material as claimed in claim 1 wherein the apex parts of the elements are formed from balsa wood.
Claim 10
Dependent Claim 29 words
Rod material as claimed in claim 1 wherein the fibre reinforced plastics of the base parts of the elements are formed from fibre reinforced epoxy, phenolic or polyester resins.
Claim 11
Dependent Claim 45 words
Rod material as claimed in claim 1 wherein the fibres of the fibre reinforced plastic bases of the elements are laid both lengthwise of the elements and across the elements to lie both lengthwise and around the outer wall of the elongate member formed therefrom.
Claim 12
Dependent Claim 27 words
Rod material as claimed in claim 1 wherein the fibres of the fibre reinforced plastics base parts of the elements comprise carbon, kevlar, boron or glass fibres.
Claim 13
Dependent Claim 20 words
Rod material as claimed in claim 1 wherein triangular section elements are bonded together to form a pentagonal cross-section member.
Claim 14
Dependent Claim 23 words
Rod material as claimed in claim 1 wherein triangular section elements are bonded together to form an elongate member of hexagonal cross-sectional shape.
Claim 15
Dependent Claim 23 words
Rod material as claimed in claim 1 having an end with an inset sleeve adapted to receive a dowel in close fitting relationship.
Claim 16
Dependent Claim 23 words
Rod material as claimed in claim 1 having an end with a projecting dowel adapted to engage a sleeve in close fitting relationship.
Claim 17
Dependent Claim 40 words
Rod material as claimed in claim 1 having an end with an inset sleeve adapted to receive a dowel in close fitting relationship and an opposite end with a projecting dowel adapted to engage a sleeve in close fitting relationship.
