WIRBEL, INSBESONDERE SCHRAUBENWIRBEL FUER SAITENINSTRUMENTE

摘要

A handle to facilitate more rapid winding/or unwinding of a string of a musical instrument is disclosed. The handle replaces the usual knob, and includes a crank member which can be pivoted out from a concealed storage position to an operative extended position, thereby achieving a greater radius of rotation and a resultant fast-wind capacity for the device.
