| Abstract: |
A magnetic spinner toy includes a plurality of spinner bodies mounted one adjacent another on a support base for independent rotation. A plurality of permanent spinner magnets are mounted on each spinner body at circumferentially spaced positions for rotation closely adjacent the spinner magnets of the adjacent spinner body. The magnetic poles of the confronting surfaces of the spinner magnets of adjacent spinner bodies are either of like polarity, whereby to repel each other, or of unlike polarity, whereby they attract each other. A pair of permanent levitating magnets are mounted one on each spinner body and the other on the support base with the confronting faces of the pair being of the same polarity, whereby to repel each other and thus maintain the spinner body spaced from the support base to eliminate frictional engagement between them. A battery-operated electromagnetic drive mechanism may be associated with at least one spinner body for actuation by movement of the spinner magnets of said spinner body to move said spinner body by magnetic repulsion, whereby to extend the operating time of the magnetic spinner toy.

First Claim:
Show all 8 claims |
We claim:
1. A magnetic spinner toy, comprising:
- a) a support base,
- b) a plurality of spinner bodies of non-magnetic material each including a body axle member and a magnet support arm member extending radially outward from the body axle member,
- c) a plurality of permanent spinner magnets mounted on the support arm member of each body in circumferentially spaced apart relation radially outward of the axis of rotation of the body axle member, the magnetic poles of all spinner magnets on each spinner body being of identical orientation,
- d) pivot means on the axis of the body axle member of each spinner body mounting the plurality of bodies on the support base for free spinning rotation in laterally spaced apart arrangement with the circumferential rotation planes of the spinner magnets on the support arm members of the plurality of bodies positioned closely adjacent to each other, the spinner bodies projecting from the base and exposed for hand manipulation for initiating spinning rotation of any of said spinner bodies,
- e) the magnetic poles on the confronting faces of the spinner magnets of adjacent spinner bodies providing magnetic repulsion or attraction therebetween for rotation of the spinner bodies freely through random revolutions in one direction or the other.
