Abstract
A spinning figurine toy has a weighted skirt or disc to provide angular momentum, a lower spindle, a spring attached to the lower spindle, a foot inserted into the lower end of the spring, and a rod fixed in the foot and able to move vertically within the lower spindle. When the toy is spun upon the foot, bouncing or jumping motion may be imparted to the toy by dropping it from a height because of the resilient nature of the spring. A pull-string operated hand launcher having a helical spindle on top fits into a corresponding helical aperture in the foot to provide a means of setting the toy in motion at high speed and of releasing it.
Claims5
A spinning toy comprising
- a spinning body capable of spinning like a top about an axis of rotation and having a bottom having a central region adjacent the axis of rotation;
- spring means fastened to the spinning body and extending below a point at or near the central region of the spinning body, the spring means aligned generally with the axis of rotation of the spinning body to absorb compressive force in the direction of the axis of rotation of the toy;
- foot means attached to a bottom end of the spring means and located below the spring means when the toy is in use, the foot means having a bottom end having a flat circular rim around its periphery to permit the toy to roll upon a surface when the spinning body is spinning, the diameter of the flat circular rim being sufficiently large to permit the foot of the spinning body to roll upon the rim as it spins thereby causing the toy to move laterally when in use:
- a generally circular, vertical extending bore in the bottom surface of the foot means, the bore having a first helical thread formed therein;
- a hand-operated launcher means for spinning the spinning body and launching it onto the surface, the launcher means comprising
- a launcher body adapted to be held in a hand of a user,
- a spindle means vertically mounted in the launcher body, capable of rotation about its vertical axis and having an upper end accessible through an opening in a top surface of the launcher body and extending relatively close to or protruding slightly above the top surface of the launcher body,
- a pull-string wrapped around the spindle means so that pulling on the pull-string causes the spindle means to rotate about its vertical axis,
- a second helical thread located at the upper end of the spindle means and adapted to thread loosely into the first helical thread within the vertically extending bore in the foot means,
- whereby when the pull-string is pulled causing the spindle means to rotate, the first helical thread securely engages the second helical thread, causing the foot means and thereby the spinning toy to rotate, and when the spindle means stops rotating the foot will continue to rotate, due to the angular momentu the first helical thread to unthread itself from the second helical thread, and thereby tending to cause the foot means and thus the spinning top to rise out of the launcher.

- rectilinear support rod located within the spring means between the foot means and the spinning body, the support rod being fixedly attached to the foot means, having an upper portion having a non-circular cross-section, and having a length sufficient to protrude into the body at all times;
- an aperture in the bottom of the spinning body having a non-circular cross-section corresponding to the cross-section of the upper portion of the support rod to receive the support rod such that the support rod may move relatively freely only in the direction of the axis of the support rod but may not rotate with respect to the support rod when the toy is being launched;
- and
- rod retention means for retaining the upper end of the support rod within the aperture at all times.

- an aperture in the bottom of the spinning body sized to receive the support rod such that the support rod may move relatively freely only in the direction of the axis of the support rod;
- a slot communicating with the aperture into which the support rod projects within the spinning body, the slot having a cross-section of a size and shape to receive the upper end of the support rod so that the support rod may move freely in the direction of the axis of the support rod, but may not rotate with respect to the spinning body;
- rod retention means for retaining the upper end of the support rod within the aperture at all times;
