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, i...
A transport aid for a narrow oblong object, said object bounded by a parallelepiped having a narrow first end longitudinally opposite a narrow second end, between which ends communicates opposing narrow longitudinal sides and opposing broad longitudinal faces, a plane of weight symmetry parallel said opposing broad longitudinal faces, said transport aid comprising: single wheel means having medially defined a plane of rotation for balancingly supporting said first end in coaction with manual support and propulsion of said second end; and coupling means h...
