Topside spring tension adjuster for bass drum pedals with variable pivot point spring rotor
Abstract:
Described is a drum foot pedal with a tension adjuster for adjusting the tension of the spring and corresponding return action of a beater. The device includes a foot pedal and a beater bracket operably connected with the foot pedal such that the beater bracket is actuated in response to force applied to the foot pedal. A rocker component is attached with the beater bracket such that rotational motion of the beater bracket causes a rotational motion of the rocker component. A swivel component is connected with the rocker component. Further, a spring is attached with the swivel component for biasing the beater bracket to force a return action of a beater when force is removed from the foot pedal. Finally, a spring tension adjuster connected with and between the swivel component and spring, the spring tension adjuster operable for allowing a user to selectively adjust tension of the spring.
