Abstract
An improved spinning toy comprised of a primary flywheel affixed near one end of a shaft penetrating the central axis, a symmetrical handle having a specific size, shape, and relational location rotatably connected about the shaft penetrating it; a smaller secondary flywheel near the lower end of the handle through which the shaft penetrates, two end caps having conical terminations, flat protruding surfaces on the sides of the handle, a tangential line of the handle having the lower end tip in the line, and a hole in the handle through which a string passes.
Claims4
A spinning toy comprised of:
- a rigid shaft having a top end and a lower end;
- a top end tip affixed to the top end of the shaft and a lower end tip affixed to the lower end of the shaft;
- a primary flywheel located adjacent the top end tip, having a symmetrical shape about the shaft as a central axis, and affixed to the shaft through the central axis;
- a handle having a symmetrical shape about the shaft as a central axis and having a widest diameter and a longitudinal length approximately equal and further having an upper end on the handle's central axis nearest the primary flywheel and a lower end opposite thereto and a center in between, and having the widest diameter of the handle located between the upper end and center;
- the handle is rotatably connected to the shaft through the handle's central axis, adjacent the primary flywheel at the upper end and adjacent to the lower end tip at the lower end of the handle;
- the lower end tip and the primary flywheel are located on the rigid shaft to retain the handle in a rotatable position on the shaft;
- a tangential point on the handle between the upper and lower ends of the handle and defined by the tangential line of the handle that has as one point the lower end tip;
- a symmetrical secondary flywheel smaller than the primary flywheel, through which the shaft penetrates such that the shaft is the central axis about which the secondary flywheel is symmetrical, and located near the lower end of the handle;
- a string attached to the shaft;
- a hole in the handle through which the string passes.

A spinning toy comprised of:
- a rigid shaft having a top end and a lower end;
- a top end tip affixed to the top end of the shaft and a lower end tip affixed to the lower end of the shaft, each having essentially a conical shape near the end of each tip;
- a primary flywheel located adjacent the top end tip, having a symmetrical shape about the shaft as a central axis, and affixed to the shaft through the central axis;
- and further having a diameter perpendicular to the central axis;
- a handle having a symmetrical shape about the shaft as a central axis and having a widest diameter perpendicular to the central axis and a longitudinal length perpendicular to said widest diameter, which lengths are within 20% of each other and the primary flywheel diameter, and further having an upper end on the handle's central axis nearest the primary flywheel and a lower end opposite thereto and a center in between, and having the widest diameter of the handle located between the upper end and center;
- the handle is rotatably connected to the shaft through the handle's central axis, adjacent to the primary flywheel at the upper end and adjacent to the lower end tip at the lower end of the handle;
- the lower end tip and the primary flywheel are located on the rigid shaft to retain the handle in a rotatable position on the shaft;
- a tangential point on the handle approximately midway between the upper and lower ends of the handle and defined by the tangential line of the handle that has as one point the lower end tip;
- a symmetrical secondary flywheel smaller than the primary flywheel, through which the shaft penetrates such that the shaft is the central axis about which the secondary flywheel is symmetrical, and located adjacent the handle at the lower end of the handle;
- a string attached to the shaft;
- a hole in the handle located near the middle of the handle, through which the string passes.
