Spool braking device for fishing reel
First Claim
1. A spool braking device for a fishing reel attached to a fishing rod in a detachable manner for use with a fishing line, the spool braking device comprising:
- a rotatable spool, arrangeable in the reel, for winding and unwinding the fishing line;
a brake mechanism for electronically braking rotation of the spool;
an acceleration sensor attached to the fishing rod for detecting swing acceleration of the fishing rod that is produced when the fishing rod is swung and generating an acceleration signal; and
a brake control unit coupled to the acceleration sensor, wherein the brake control unit drives the brake mechanism and determines whether or not to brake the spool based on the acceleration signal, and wherein the brake control unit determines, based on the acceleration signal, an estimated casting distance of the fishing line from a casting point to a landing point where the fishing line lands on water, and drives the brake mechanism based on the estimated casting distance, and wherein the brake control unit includes a parameter setting unit for setting at least one initial parameter and changing a casting condition, and determines the estimated casting distance based on the at least one initial parameter and the acceleration signal, and wherein the at least one initial parameter includes a height parameter indicating a height of the fishing rod when the fishing line is cast from the fishing rod as the fishing rod reaches a casting swing termination position.

Abstract
A spool braking device and a spool braking method for increasing spool braking capability. The spool braking device includes a reel attached to a fishing rod in a detachable manner. A rotatable spool is arranged in the reel. A fishing line is wound to the spool. A brake mechanism electronically brakes rotation of the spool. An acceleration sensor detects swing acceleration produced when the fishing rod is swung and generates an acceleration signal. A brake control unit determines whether or not the spool needs to be braked based on the acceleration signal and drives the brake mechanism.

7. A spool braking device for a fishing reel, the reel being attached to a fishing rod and for use with a fishing line, the spool braking device comprising:
-
a rotatable spool for winding and unwinding the fishing line; a brake mechanism for electronically braking rotation of the spool; an acceleration sensor, attached to a distal portion of the fishing rod, for detecting swing acceleration of the fishing rod produced when the fishing rod is swung, the acceleration sensor generating an acceleration signal; and a brake control unit, coupled to the acceleration sensor and the brake mechanism, that drives the brake mechanism, wherein the brake control unit determines whether to brake the spool based on the acceleration signal, and wherein the brake control unit determines, based on the acceleration signal, an initial speed and a projection angle of the fishing line when the fishing line is cast from the fishing rod as the fishing rod reaches a casting swing termination position, and the brake control unit drives the brake mechanism when the projection angle exceeds a predetermined maximum projection angle that corresponds to the initial speed. - View Dependent Claims (8, 9)

10. A method for controlling braking of a rotatable spool arranged in a fishing reel, the reel being attached to a fishing rod in a detachable manner, and the reel including a brake mechanism for electronically braking rotation of the spool, and wherein the spool is wound with a fishing line, the method comprising:
-
generating an acceleration signal indicative of acceleration of the fishing rod using an acceleration sensor attached to the fishing rod to detect swing acceleration produced when the fishing rod is swung; driving the brake mechanism by determining whether or not to brake the spool based on the acceleration signal; determining an initial speed and a projection angle of the fishing line when the fishing line is cast from the fishing rod as the fishing rod reaches a casting swing termination position based on the acceleration signal; and driving the brake mechanism when the projection angle is greater than a predetermined maximum projection angle that corresponds to the initial speed. - View Dependent Claims (11, 12, 13, 14, 15)
