Patent ID: 8444107

Claim:
Apparatus for supporting a load, comprising: a pivot apparatus coupled to said load and movable with said load; a base stationary relative to said pivot apparatus; at least two areas of support between said pivot apparatus and said base, wherein respectively opposite force components generated by earth gravity pulling said load downward a) intersect at said load; and b) are at said two areas of support; one of said areas of support is vertically higher than another of said areas of support; said two areas of support move along at least one curved path between a vertically higher elevation and a vertically lower elevation to tilt said load; said two areas of support move in a direction between said vertically higher elevation and said vertically lower elevation causing said load to rotate about an axis which intersects said load; an adjuster bracket attached to said base, a holding block coupled to and movable with said pivot apparatus, and an actuator between said adjuster bracket and said holding block, wherein responsive to said actuator drawing said holding block towards or away from said adjuster bracket, said load rotates about said axis which intersects said load.
