ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a structure for confirming the adjusted position of a drum pedal.
In recent years, many drum pedals designs permit the height position of the pedal plate and the amplitude and angle of the beater to be freely adjusted. In addition, some pedals enable independently adjusting the height position of the pedal plate and the amplitude and angle width of the beater. This has made it possible to finely adjust the height position of the pedal plate and the amplitude and angle width of the beater (stroke volume) to an individual performer's preference.
In these known drum pedals, however, if the height position of the pedal plate or the amplitude and angle width of the beater are adjusted many times, it sometimes becomes impossible to determine the original position of adjustment, thereby making it impossible to restore the height position of the pedal plate or the amplitude and angle width of the beater to their original adjusted positions.
SUMMARY OF THE INVENTION
The invention seeks to overcome the foregoing problem by providing a structure for confirming the adjusted position of the drum pedal and which is capable of enabling easy Observation of the adjusted positions of the height position of the pedal plate or the amplitude and angle width of the beater in the drum pedal.
The invention relates to a structure for confirming the adjusted position of a drum pedal. cam is fixed at the end of a beater rotary shaft, and that shaft is freely rotatably held on a support.
A spring is stretched on the cam which returns the cam and the shaft to a standard start orientation where the spring is at minimum tension. The beater rotary shaft is rotated by operating a pedal plate for causing a beater installed integrally on the beater rotary shaft to be amplitude-vibrated with respect to the drum.
The beater rotary shaft protrudes axially to the outside of the cam. A display member having a display part is fixed on the protruding part of the shaft. A position indicator for a standard position is provided on the cam. The adjusted position of the drum pedal is observable due to the display part and the standard position indicator of the cam.
In addition, the display part of the display member comprises a plurality of scales including the standard position scale. There is structure for confirming the adjusted position. The display member may be installed on and fixed on the end of the rotary shaft protruding part.
Other objects and features of the invention are explained below with reference to the drawings.
