Abstract

A multi-purpose, collapsible portable cart, for use in camping, hunting and other outdoors activities carries medical rescue carts, canoes, small boats, game, or hauled cargo by hand. The portable cart can be converted to a various uses and the portable cart can be folded down and transported within a backpack, hand carried bag, canoe or boat. It transports injured persons or cargo over long, rough terrain and it can broken down into a carrying position, by hand or by back. Its width can be varied to accommodate cargo of varying widths. Two or four wheeled versions can be assembled with axles and wheels. The cart has optional removable clamps for clamping a conventional transportable carrier, such as a stretcher or stokes-type rescue carrier bed, thereto. The objects being carried can be held by clamps, by fasteners, or through the use of insertions with longitudinally extending channels. An optional pivotable kickstand and/or tie rods can stabilize the cart in a position of rest. It is collapsible, so that it can be disassembled and carried, and then reassembled at another destination along a wilderness journey.
