Abstract: A portable sled and litter is easily and quickly assembled and disassembled, and when disassembled it can fit into a bag or container to be carried by a single person. Further, the portable sled and litter takes the form of a rigid litter (as compared to a non-rigid litter), and includes a plurality of rigid, interlocking panels that cooperate with a frame assembly. An inelastic cord extends through at least several frame assembly members and when tensioned causes the frame assembly members to engage with one another to form the frame assembly or at least a section of the frame assembly. The portable sled and litter may have adjustable and static couplings for tensioning the inelastic cord.
