Total Claims: 6
Claim 1
Independent Claim
223 words
A beater holder mounting structure fastened to a polygonal shaft of a pedal unit of a base drum to hold a beater, comprising a holder base having a shaft holder section at one end and a beater holder section at an opposite end, said beater holder section having a beater holding through hole, which receives the stem of the beater, and a screw hole perpendicularly extended from said beater holding through hole to the periphery into which a tightening up screw is threaded and stopped against the stem of the beater, wherein: said beater holding through hole is a multiple-face through hole; said beater holder section has a coupling groove at one side thereof; a retainer block is coupled to said coupling groove to hold down the stem of the beater, said retainer block comprising a L-shaped coupling flange extended from a rear side thereof and engaged into said coupling groove of said beater holder section, a vertical multiple-face through hole in alignment with said beater holding through hole of said beater holder section through which the stem of the beater passes, and a horizontal screw hole perpendicularly extended from said vertical multiple-face through hole to the periphery, and a tightening up screw threaded into said horizontal screw hole and stopped against the stem of said beater to fix the stem in place.
