Patent ID: 6978570

Claim:
An adjustable swivel base assembly comprising: (a) a planar mounting base plate defining a first major plane, (b) a pair of laterally spaced apart columnar supports affixed at a first longitudinal end thereof to said base plate and extending therefrom generally perpendicularly relative to the major plane thereof, (c) a planar bearing plate defining a second major plane and being stationarily supported on a second longitudinal end of said supports opposite said first longitudinal end thereof, (d) a planar first bearing defining a third major plane and being stationarily supported on said bearing plate on a side thereof remote from said supports, (e) a planar second bearing defining a fourth major plane and being stationarily affixed to said bearing plate and spaced from and coaxial with said first bearing, said major planes being oriented generally parallel with one another, (f) a planar rotatable swivel plate supported on and sandwiched slidably between said first and second bearings for rotation in a plane generally parallel to said major planes, said rotatable swivel plate being adapted to carry a load to be swiveled by said rotation of said rotatable plate, and (g) an indexable locking system for selectively locking said rotatable swivel plate in any one of a plurality of angularly spaced positions.
