Abstract
A fishing rod handle of variable circumference permits adjustment to fit the hand size of an individual user and retains that size until again readjusted to a different circumference. A plurality of individual longitudinal spreaders are arranged circumferentially around the handle. Axially applied screw-action forces the individual spreaders to spread of bend outward. A resilient covering over the spreaders may be proved to lend a smooth surface to the handle at various possible circumferences.
Claims13
A fishing rod handle of adjustable circumference comprising:
- a solid cylindrical core extending from a proximal butt end of said rod to a distal end, said core having longitudinal channels extending from the proximal to the distal end of said core, the proximal end of said core having a well extending further into the core and forming a shoulder within each channel;
- a spreader positioned within each channel, each spreader having a head slidably positioned within said well;
- such that, as pressure is applied to the spreaders from the proximal end, the spreaders are gradually bowed outward, thus enlarging the circumference of the handle.
A fishing rod handle of adjustable circumference comprising:
- a hollow cylindrical cage extending from a proximal butt end of said rod to a distal end, said cage having longitudinal openings extending from the proximal to near the distal end of said cage forming expanders;
- a cylindrical cap encompassing the expanders at the proximal end of the cage, said cap engaging a screw shaft longitudinally extending through a center of said cap for rotation with said screw;
- such that, as the screw shaft is screwed into said cage, said cap is pressed longitudinally distally upon said expanders, gradually causing the expanders to splay outward, thus enlarging the circumference of the handle.
A fishing rod handle of adjustable circumference comprising:
- a cylindrical shell extending from a proximal butt end of said rod to a distal end, said shell having longitudinal slots extending from the proximal to the distal end of said shell forming spreaders, an interior cylindrical surface of said shell tapering from a larger diameter surface at the proximal end to a smaller diameter surface at the distal end thereof;
- a cylindrical bullet-nosed plug screw-engageable with said shell, said plug having an exterior diameter sized to fit the larger diameter of said shell;
- and
- a screw key, sized and adapted for engaging a screw slot in an end of the plug opposite the bullet nose, said key storable on a reel seat of said rod by screw fit between a foregrip nut and a finger grip;
- such that, as the bullet nose of said plug is screwed distally into said shell from the larger to the smaller diameter surface, the plug gradually pushes the spreaders outward, thus enlarging the circumference of the handle.

A fishing rod handle of adjustable circumference comprising
- a shaft at a butt end of said rod;
- a cylindrical shell concentrically and longitudinally aligned about said shaft extending from a proximal butt end of said rod to a distal end, said shell having longitudinal slots extending from the proximal to the distal end of said shell forming spreaders, an interior of said shell tapering from a larger diameter surface at the proximal end to a smaller diameter surface at the distal end;
- a cylindrical bullet-nosed plug cylindrically and longitudinally aligned within said shell about said shaft and screw engageable with said shaft, said plug having an exterior diameter sized to fit the larger diameter of said shell;
- and
- said handle is further provided with a screw key, sized and adapted for engaging a screw slot provided in an end of the plug opposite the bullet nose, which screw key is storable on a reel seat of said rod by screw fit between a foregrip nut and a finger grip;
- such that, as the bullet nose of said plug is screwed distally onto said shaft within said shell from the larger to the smaller diameter surface, the plug gradually bows the spreaders outward, thus enlarging the circumference of the handle.
