Abstract

GEOMETRIC DESIGN FISHING ROD.

Abstract of Disclosure.
The principles of this invention apply to the incorporation of geometric forms in the tapering configuration of a fishing rod. These said geometric forms being either of sectional form, or achieved by a structural composition of varied material density within the rod shaft sections.
A rod of such geometric design would have properties in the uppermost section that would favour directional movement.
This would be merged with a section below that can flex to any angle with equal resistance, and this section will in turn be merged to a section which has properties to oppose flex by means of geometric principle. A rod so described will possess an inherant capacity to flex and recover, with a compressional and recoil action, that will favour the selected angle of the delivery stroke. The stroke of the cast will be made in a more decisive and efficient manner from a shaft of geometric design than a shaft which possess an equal radial flex character throughout its complete working length.

Description

Geometric Design Fishing Xod.

Details of Specification.
At the present time fishing rods are produced in either a solid or tubular form, and are constructed from one or more pieces, the latter being joined by some type of ferrule device. The ~eornetric design may be applied to the tapering shaft of either tubular or solid construction, that is manufactured in one or more sections~ -A rod is acknowledged to be comprised of three working zones.The tip being the upper zone, the central zone being the middle, and the butt being the lower zone. The butt drives the middle, the middle dri~es the tip, and the tip is linked by the line to the weight to be cast. The individual function of these zones are relative to the action of the rod, and its performance, and the geometric principles of the in~ention would serve to accent the shaft zone function.
The majority of rod shafts at the present time are produced in a tubutlar form. llhis is a manufacturing process which employs a circular tapering metal former around which is wrapped a section of fiber cloth that is impregnated with resin. After processing, the metal former is withdrawn, and on extraction, produces the hollow tapering tube that was moulded around it.
Solid materials are normally extruded, which produces a solid tapering form, or a system of grinding is employed to obtain the circular shape.
The factors of geometry which relate to this invention may take two forms. At one extreme the geometric design shapes for the tip may be rectangular, oval or triangular in section : these shapes favour directional mo~ion and will resist lateral movementO The described section would be mer~ed with a circular mid-section, which is a sectional form that provides an ability to flex evenly to any point.
This portion would in turn merge with an octagonal, diamond or hexagonal butt. These latter shapes resist flex in a superior manner to a circular shape. A shaft so described may be constructed by an extrusion process, or by a system of grinding, or produced in a tubular form from a manclrel shaped to mould them.
At the other extreme, the principle of geometric design may be embodied within the structural composition of the rod shaft, done by varying the material density of constructional material. This may be done by the incorporation of spines bein~ laid alon~ the shaft in the upper and lower zones of the rod. ~uch spines will contribute the necessary geometric elements to enable the rod to furlction in the manner prescribed in the inventionO

1126~10 Frorn what has been described, the directional geometry of the flex pattern of the tip will aid the cast. This will occur by the tip aligning the weight to be thrown directly behind the pulling action of the rod, ancl on release, because of the inherant directional movement of the tip, will provide a more accurate course of delivery thrust.Another improvement in rod action by the use of geometric principle in the lower portion of the shaft, will allow strength factors to be created by sectional form, rather than the addition of materials.
The inven~ion will also enable the the action of the rod to be varied, from the amounts of flex resistant ancl equal flex regions which emplo~ed in the middle ancl lower zones of the shaft. A stiff butt produces a fast action, while a slow action originates from a butt with less power. These factors hein~ relative to dynamic action.
