Patent ID: 7851957

Claim:
A rotatable support apparatus comprising: a stationary base section; an upper display section disposed above said base section; a shaft member extending through said base portion and said upper display portion, said shaft member having one end mounted to said stationary base section and defining an axis that permits rotation of said upper display section; and a pair of indexing members disposed in relation to said shaft member, said pair of indexing members including an opening sized for receiving said shaft member, each of said indexing members including a plurality of circumferentially disposed magnets each having an exposed magnetic surface, said pair of indexing members being attached to each of said upper display section and said base section, respectively, and being aligned such that a repelling field is initially established between said indexing members and in which like polarities are established between said indexing members when the upper display portion has ceased rotating to index said upper display portion relative to said stationary base portion, wherein the polarities of said plurality of circumferentially disposed magnets of each indexing member alternate in relation to each other such that a repelling magnetic field is created between said pair of indexing members during portions of rotation of said upper display portion and an attractive magnetic field is created during other portions of said rotation.
