Patent ID: 7855331

Claim:
A pedal system for a drum, comprising: a support element, having a pedal and at least one upright frame, the pedal being swayable between a release position and a percussion position, an axle being rotatably disposed on the upright frame; a connecting shank, disposed on the axle in a rotational operative relationship; a transmission element, connecting between the pedal and the connecting shank, the connecting shank being rotatable as the pedal pivoting between the release position and the percussion position; and a returning element, comprising a connecting body, a rod unit, a positioning element and a resilient member, the connecting body being disposed on the axle in a rotational operative relationship, the resilient member connecting between the connecting body and a connecting end of the rod unit, the resilient member providing a resilient force to retain the axle to a predetermined position so as to move the pedal to the release position, the connecting end of the rod unit being movable with respect to the support element so as to adjust an angle included between an orientation of the resilient member and that of the upright frame, the positioning element selectively fixing a relative position between the rod unit and the support element, so as to further fix the angle.
