Abstract:
A structure for confirming the adjusted position of a drum pedal with respect to a drumhead, wherein the drum pedal comprisesa support; a beater rotary shaft supported for rotation on the support; a beater on the shaft for being rotated toward and away from the drumhead as the shaft is rotated respectively in opposite directions;a pedal adapted to be stepped in by a performer; a connection between the beater rotary shaft and the pedal operable such that as the pedal is stepped in, the shaft is rotated in one direction with respect to the support to move the beater to beat the drumhead, and as the pedal is released, the shaft is rotated in the direction opposite the one direction to move the beater away from the drumhead;a cam attached on the shaft to rotate with the shaft,the cam having a rotation orientation on the shaft which is adjustable around the shaft and the cam being attachable to the shaft to rotate together with the shaft, at a selected rotation orientation of the cam on the shaft;a spring stretched between the cam and the support, the spring biasing the cam to a standard orientation with respect to the support and thereby rotating the shaft to a position then corresponding to a position to which the cam is biased by the spring, and the cam, the beater and pedal all being so connected with the shaft that the initial separation of the beater from the drumhead and the initial position of the pedal before the pedal is stepped in are set by the orientation of the cam around the shaft;a standard position indicator provided on the cam;a display member attached on the shaft and rotatable with the shaft, the display member having a display region with indicators thereon, and the indicators are positioned to indicate the rotated position of the shaft and the display member thereon with respect to the standard position indicator on the cam.
