ABSTRACT:
The flexible cargo container of this cart partially deflects inside-out as the cart truss supporting it changes orientation pivoting on wheels rotatably mounted at the aft lower extremity of downwardly projecting support struts to serve as a chair. Leg supports providing static stability are pivotably mounted to extend forward thereby resisting tipping moments about the wheel axle with payload located intermediate thereto. Rotation of the forward end of the cart upwardly and rearwardly brings the rearward upper connect strut in contact with the support surface exposing the underside of the flexible container inverted to concavity, resulting in a chair of supine positioning. Support struts making up the truss fold about pivotable connections yielding a non-use flat geometry for storage. Snap releasable interconnections dissociate struts from the truss in further disassembly.
