Fishing reel with electronic antibacklashing features dependent on a sensed line condition
First Claim
1. A fishing reel, comprising:
- a spool for holding and releasing a length of fishing line;
determining means for determining an overrun condition of the fishing line being released from the spool, the determining means comprising a line motion sensor including a rotatable member rotatable in response to movement of the fishing line during a cast and sensing means for sensing the rotation of the rotatable member and generating a line motion signal depending on the sensed rotation of the rotatable member; and
an electronically variable brake controlled depending on the line motion signal and couplable with the spool for applying a variable braking force to resist rotation of the spool in response to the determined overrun condition of the fishing line being released from the spool.

Abstract
An antibacklashing fishing reel. A spool holds and releases a length of fishing line. An overrun condition of the fishing line being released from the spool is determined by a line motion sensor. The line motion sensor includes a rotatable member rotatable in response to movement of the fishing line during a cast and a sensor for sensing the rotation of the rotatable member. The sensor generates the line motion signal depending on the sensed rotation of the rotatable member. An electronically variable brake is controlled depending on the line motion signal for applying a variable braking force to resist rotation of the spool in response to the determined overrun condition of the fishing line being released from the spool. When the line motion signal indicates that the line is being played out from the spool slower than the spool is releasing it, an overrun condition is determined and the spool is braked to prevent the occurrence of a backlash. The overrun condition may also be determined a variable electrical resistance mechanism for determining the electronic status signal having a value dependent on the tension of the line being release from the spool. The braking of the spool is controlled so that a variable braking force is applied depending on the sensed line tension as determined by the variable electrical resistance mechanism.

12. A fishing reel, comprising:
- a spool for holding and releasing a length of fishing line;
an electronically variable brake couplable with the spool for applying a braking force to resist rotation of the spool during casting to prevent the spool from overrunning the length of fishing line being released from the spool, the electronically variable brake comprises a first friction element rotatable with the spool and a second friction element held stationary relative to the rotation of the spool, and a shape memory alloy member for driving the first friction element into contact with the second friction element in response to the determined overrun status of the fishing line being released from the spool;determining means for determining an overrun status of the length of fishing line being released from the spool and generating an electronic status signal dependent thereon, the determining means including a variable electrical resistance mechanism for determining an electronic status signal having a value dependent on the tension of the line being release from the spool; and
controlling means receptive of the electronic status signal for controlling the electronically variable brake to apply the braking force to resist rotation of the spool during casting when the determining means determines an overrun status so that a braking force is applied when the overrun status determined by the determining means indicates that the spool is overrunning the length of fishing line being released, the braking force being applied until the overrun status determined by the determining means indicates that the spool is not overrunning the length of fishing line so as to prevent the spool from further overrunning the length of fishing line being released. - View Dependent Claims (13, 14)
