ABSTRACT:
A litter apparatus including an expandable framework is arranged to have secured thereon a cover. The framework includes spaced parallel first tubular bodies, each having a second tubular body, with each second tubular body having a retractable third tubular body that in turn includes a fourth tubular body, wherein the tubular bodies are expandable relative to one another, with first and second forward expandable tubes mounted orthogonally between the first tubular bodies and first and second expandable rear tubes mounted orthogonally between the fourth tubular bodies, whereupon the actuation of plungers within the first tubular bodies permits release of the tubular bodies relative to one another in an expanded orientation relative to one another.
