Abstract
A tumbler toy containing typically four ramp surfaces placed radially at a fixed angle. When a player rotates the toy, all of the ramp surfaces rotate simultaneously and a ball can be made to roll along the ramp surface until it encounters an opening in the ramp surface. When the ball descends through this opening it is deflected by a guide placed along the ramp surface. With experience and practice a player can rotate the tumbler toy either clockwise or counterclockwise and keep the ball moving from ramp surface to ramp surface indefinitely.
Claims4
A tumbler toy, comprising in combination:
- (a) four ramp surfaces in a radial configuration around a central core having an elongated axis, wherein said ramp surfaces are located at a ninety degree angle with respect to each other about said core, each curved wall section having an opening of such dimension as to allow a ball to pass through at only one end thereof, with the openings located so that each ramp surface has the openings at diametric opposing ends thereof, said openings being positioned on the curved wall sections so that each opening is spaced along its respective common axial line when the respective curved wall section is in an upward verticle position;
- (b) a guide affixed to each of said ramp surfaces whereby said ball falling through any of said openings may be redirected in its path of travel so as to redirect any radial motion, which would tend to dislodge said ball from said tumbler toy, into an axial motion, thereby creating a possibility of manipulating the invention so as to cause said ball to fall through another said opening in another said ramp surface;
- and,
- (c) means for rotating said multiplicity of ramp surfaces axially and radially.
