Abstract:
An omni-directional wheel, comprising;(a) a frame including an upper portion for affixing the frame to an under-side of a weight bearing surface, at least two side walls, and a central cavity defined by the side walls for receiving at least one spherical wheel; (b) at least two wheel bearing means connected in axial alignment to the side walls for rotation of the wheel about affixed axis passing through the wheel bearing; (c) at least two wheel seat means each having one side connected in axial alignment to the wheel bearing means and an opposite conical face wherein the conical faces are disposed in opposite axial alignment for slidably mounting the wheel between the faces for rotation of the wheel about an axis perpendicular to the fixed axis, (d) an upper load bearing means connected to the frame which biases against an upper surface of the wheel; and (e) a means for adjusting a force of the conical faces against the wheel.
