초록

An obstacle traversing wheel assembly that rolls easily without dragging over electrical cords, trash and debris includes a primary wheel that is journaled on an axle which is attached to a load carrying frame. At least four independently rotatable secondary wheels are mounted around the circumference of the primary wheel at locations equidistant from each other and from the primary wheel axle. The secondary wheels are all of the same diameter and are spaced apart on the primary wheel at a distance that is less than the diameter of a secondary wheel. The...

1. A wheel assembly comprising:a primary wheel including a generally planar wheel holder that is rotatable about a central axis, said wheel holder comprising two parallel, spaced apart plates, said plates supporting a plurality of axles extending perpendicularly therebetween, one axle for each secondary wheel; and at least four secondary wheels of equal diameter rotatably mounted on the holder at locations equidistant apart, one from the next, and equidistant as well from the central axis of the holder, the distance between each wheel location being less...
