Abstract
Abstract A cymbal clamping device used in a high-hat stand including a lock nut, a pair of felt washers for retaining a cymbal, and a clutch nut which are fitted on an attachment fixture mounted at the top end of the high-hat stand. A pair of parallel screw mounting brackets extend from one side of the lock nut so that the space between the screw mounting brackets is reduced when a clamp screw engaging with the screw mounting bracket is tightened so that the elastically deformed lock nut is positionally secured on the high-hat stand without getting loosened.

Claim 1
Independent Claim
299 words
A cymbal clamping device being secured to an extension rod, said device for use in a high-hat stand that includes telescopic upper and lower pipes, legs attached to a lower end of said lower pipe and an extension rod provided in said upper and lower pipes, said cymbal clamping device comprising: a cylindrical attachment fixture fitted on an upper end of said extension rod, said attachment fixture being provided with an external thread; a pair of washers fitted on said attachment fixture for holding a cymbal in between; a U-shaped lock nut screwed to said attachment fixture so as to be positioned above said washers, said lock nut having a pair of screw mounting brackets so that one of said screw mounting brackets has a screw attachment hole and another of said screw mounting brackets has a screw hole so that said screw attachment hole and screw hole are horizontally coaxial; a first clamp screw brought into said screw hole of one of said screw mounting brackets and screwed to said screw hole of said another of said screw mounting brackets so that a distance between said two screw mounting brackets is decreased when said first clamp screw is tightened; a clutch nut screwed to said attachment fixture so as to be positioned below said washers, said clutch nut having a pair of screw mounts so that one of said screw mounts has a screw attachment hole and another of said screw mounts has a screw hole so that said screw attachment hole and said screw hole are vertically coaxial; and a second clamp screw brought into said screw attachment hole and screwed to said screw hole of said clutch nut so that a distance between said two screw mounts is decreased when said second clamp screw is tightened.
