Abstract
A portable, collapsible stretcher has frame poles, each of which have a medial joint which folds in one direction and two outer joints which fold in the opposite direction. A wedge is insertable into the medial joint to support the weight when the stretcher is extended. The outer joints have a locking mechanism which is operated by a linkage interconnecting the spreader bars and the folding legs. As the stretcher is extended, the outer joints are locked and the legs are unfolded from their normal position against the frame poles.
