| Abstract: |
A magnetically levitated spinning axle display apparatus having a base assembly and an axle assembly. The base assembly includes a base platform member having a plurality of base magnets that are disposed spaced apart along an upper surface thereof. The platform member has an upstanding wall forming an axle support member disposed at one end. The axle assembly includes a plurality of disc shaped magnets disposed spaced apart along the rod and coordinate with individual ones of the base magnets when a first or second rod end portion is engaged in abutting contact with the upstanding axle support member. The polarity configurations of the rod magnets and the base magnets are repulsive to one another to permit free floating levitation of the rod above the base and to generate a longitudinal lateral force sufficient to keep a rod end contacted with the upstanding axle support. A plurality of alternate embodiments are created through varying the shape configurations and polarity configurations for both the rod and base magnets. In another alternate embodiment, a single ring magnet is provided to the rod which is repulsed by a coordinate base magnet disposed along an upper surface of a base member. An upstanding axle support including a bore hole is provided to engage a pointed end of the rod to maintain the axle in a horizontally levitating position.

I claim:
1. A magnetically levitated spinning axle display apparatus comprising in operative combination:
- a) a rod member having a first front end portion and a second rear end portion;
- b) a first plurality of magnets disposed spaced apart along said rod member, each of said rod magnets having an axial center aligned coordinate with a longitudinal axis of said rod member:
- c) a base member having a first front end portion and a second rear end portion;
- d) means for lateral support of only said rod first front end portion, said lateral support means disposed adjacent said base member front end portion; and
- e) said base member having a second plurality of magnets disposed spaced apart adjacent an upper surface thereof, each of said second plurality of magnets having a polarity oriented to repulse the polarity of said first plurality of magnets, said second plurality of magnets selectively disposed in substantially coordinate alignment with selected ones of said first plurality of magnets to permit said rod to spin about its longitudinal axis in a levitated state above said base member for prolonged periods with a minimum of drag associated with magnetic frictional forces and rod first end support frictional forces.
