ABSTRACT:
In aid of a person transporting a narrow oblong object traversing obstacles of various heights, the object is supported at one end by a single wheel disposed adjacent the dihedral intersection of a narrow end and a narrow longitudinal side, the rotational plane of the wheel coinciding with a plane of weight symmetry of the narrow oblong object to reduce tipping tendency when support and propulsion is provided by the person manually at an end opposite the wheeled end. Various means are disclosed for coupling the single wheel to the narrow oblong object, including concave socket and clamp means. Adjustment is provided for coinciding wheel rotational plane with the plane of weight symmetry.
