ABSTRACT:
A wheeled arrangement, particularly a wheeled vehicle such as a wheelchair, includes two wheels (12,14) mechanically interconnected by a linkage including an inclined pivot (16) such that when forward movement of one wheel is obstructed continued forward movement of the arrangement and of the other wheel causes the one wheel to lift relative to the other wheel by rotation on the inclined pivot. Such an arrangement is capable of climbing a step or other obstacle having a greater height in relation to the diameter of the wheels than is possible with conventional arrangements.
