发明名称 Tethered top usable in two ways
摘要 Disclosed herein is a whistle toy which is actuated by the oscillatory motion of the user in which two strings threaded on the toy member causes the toy to rotate in such a manner that oval shaped holes disposed on the outer periphery of the toy generate a whistling affect while the toy is being rotated. The toy comprises spaced halves connected by two shafts which together form an oblong connecting means. A string may be secured to the oblong connecting means to prepare the toy for use as a yo-yo. Handles are disposed at the extremities of the string so that the string can be easily grasped for providing the oscillatory motion necessary to make the whistling affect.
