Elements for supporting wheels above ground and device for connecting the elements

摘要

Two flat, elongated support plates are arranged to form the shape of an X as viewed from the side. A base plate connects the bottom ends of the support plates together. A concave plate connects the top ends of the support plates together with the concave facing upwardly. A pair of these elements can be connected together by an elongated telescopic member that is secured at each end to a corresponding element by a hinge.
