发明名称 Piano pedal assembly
摘要 In a piano pedal assembly adapted to control the duration and amplitude of musical tones or notes generated by a piano, the individual pedals of the assembly when attached to the piano, are maintained in their normal position under pressure and adapted when depressed to pivot about a pin. The assembly is mounted on a support such as a base plate, and a pair of pedal mounting blocks having a cylindrical opening, for securing opposite sides of the pivot pin, are mounted within openings in the base plate. The pedal mounting blocks are formed from a low friction material such as Nylon or Teflon and function to provide and maintain precise registration of the individual pedals within the assembly. The piano pedal assembly utilizes fewer and less complex parts and components than prior art assemblies whereby the assembly time and fabrication cost of pedal assemblies are substantially reduced.
