Abstract
A collapsible, foldable support structure and conveyance has a frame assembly with multiple interconnected frame members, junction blocks located at intersecting ends of some of the frame members, and wheels attached to the junction blocks or directly to frame members. Fixtures are attached to or integrally formed with the junction blocks for mounting of wheels or other conveyances or components to the frame assembly. A support structure is attached to the frame assembly to support a load such as a human or cargo or both. In a folded configuration, the frame members are moved into a generally parallel arrangement and the junction blocks and conveyances attached to the junction blocks or frame members are drawn together.
