Abstract
Abstract In construction of an upper cymbal fastening assembly in which a felt washer unit holding an upper cymbal is clamped between an upper lock nut unit and a lower clutch nut unit both arranged on a tubular holder inserted over an extension rod, the clutch nut unit is made up of a pair of locally joined sections one of which is elastically deformable toward the other when a vertical force is applied thereto. The elastic deformation brings said pair of sections into firm pressure contact with the tubular holder thereby preventing slacking of the clutch nut unit due to vibrations during performance of the hi-hat cymbal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
An upper cymbal fastening assembly for a hi-hat cymbal comprising an elongated tubular holder inserted over an extension rod and made up of an upper main body and a lower threaded extension, a felt washer unit inserted over said threaded extension of said tubular holder in order to clamp an upper cymbal, a lock nut unit screwed over said threaded extension of said tubular holder at a position above said felt washer unit, a clutch nut unit screwed over said threaded extension of said tubular holder at a position below said felt washer unit in order to clamp said felt washer unit in cooperation with said lock nut unit, said clutch nut unit being made up of upper and lower sections coupled to each other via a local joint whilst leaving a horizontal gap, and one of said two sections being constructed elastically deformable about said local joint towards the other of said two sections when a vertical force is applied thereto.
