Patent ID: 8203063

Claim:
A portable tuning apparatus for tensioning and tuning a drumhead of a percussion instrument, comprising: a plurality of keys, each of said keys comprising a pair of opposing connector arms separated by a cranked section, wherein said opposing connector arms extend perpendicularly from opposing ends of said cranked section, wherein a first of said opposing connector arms of said each of said keys is configured to engageably rotate a lug of a plurality of lugs that support said drumhead of said percussion instrument, and wherein a second of said opposing connector arms of said each of said keys is configured to slidably engage with one of a plurality of openings on a rotatable tuning plate; and said rotatable tuning plate comprising said openings arranged at predetermined locations on said rotatable tuning plate, wherein a rotation of said rotatable tuning plate causes said second of said opposing connector arms of said each of said keys slidably engaged with said one of said openings on said rotatable tuning plate, along with said cranked section of said each of said keys to orbitally revolve about said first of said opposing connector arms of said each of said keys, wherein said orbital revolution of said second of said opposing connector arms along with said cranked section of said each of said keys causes an axial rotation of said first of said opposing connector arms of said each of said keys engaged on said lug; whereby said axial rotation of said first of said opposing connector arms of said each of said keys rotates said lug and imparts a uniform tension to said lugs that support said drumhead of said percussion instrument for said tensioning and said tuning of said drumhead of said percussion instrument.
