Abstract
The hoop clamping system for bass drum assemblies features an assembly attached to the foot pedal's floor plate into which the handle bolt is attached and made easily accessible from the side of the pedal. The toe clamp is activated by a pivoting cam, one end of which is under the heel of the toe clamp; the other in contact with the handle bolt. Turning the handle bolt causes the cam to lift or lower the heel of the toe clamp resulting in the desired clamping action. This hoop clamp system provides greater range of travel for the foot board, and substantially improves accessibility to the handle bolt for ease of adjusting the toe clamp. This hoop clamping system further reduces unwanted vibration and lowers manufacturing costs.
