Automatic hook-setting and fish alerting rod holder with adjustable sensitivity

A method for automatically setting a fishing hook using a biased rod holder, the method comprising:

• positioning a handle of a fishing rod within a rod-receiving member, wherein the rod-receiving member is maintained stationary relative to a base assembly when in a cocked position;
• engaging a sear assembly to hold the rod-receiving member in a the cocked position against a primary biasing force;
• adjusting a release threshold by applying a biasing counter-torque to the sear assembly to offset a static torque generated by the weight of the fishing rod;
• wherein the biasing counter-torque is applied to the sear assembly at a first radial distance from a sear pivot axis, and the primary biasing force generates a frictional torque at a latching surface located at a second radial distance from the sear pivot axis;
• wherein the first radial distance is greater than the second radial distance, thereby establishing a mechanical advantage that substantially reduces the influence of the frictional torque relative to the biasing counter-torque;
• and releasing the sear assembly via a downward deflection of the fishing rod, wherein the downward deflection applies a force to an actuator interface of the sear assembly through an opening in an outer wall of the rod-receiving member.

An automatic hook-setting rod holder comprising:

• a base assembly;
• a rod-receiving member pivotally coupled to the base assembly;
• a primary biasing element urging the rod-receiving member toward a released position;
• and a sear assembly configured to releasably maintain the rod-receiving member in a cocked position, wherein the sear assembly comprises an actuator interface positioned to receive force from a fishing rod;
• wherein the rod-receiving member defines a longitudinal receiving cavity configured to support a handle of the fishing rod while constraining the handle against vertical disengagement during a hook-setting motion;
• wherein a longitudinal position of the fishing rod within the longitudinal receiving cavity establishes a moment arm between a center of gravity of the fishing rod and a fulcrum point of the rod-receiving member, such that a weight of the fishing rod produces torque about the fulcrum point;
• and wherein a release threshold of the sear assembly is adjustable by altering the longitudinal position of the fishing rod relative to the actuator interface, thereby varying a distance between the center of gravity of the fishing rod and the fulcrum point to vary a torque applied to the actuator interface.
