Abstract: A lightweight structure for oil and acrylic painting that converts to a self-contained backpack, capable of transporting a canvas, paint supplies and the like. The structure is composed of three legs (31L, 31R, 31B) joined at the top, braced by a detachable pack frame (175) suspended between the legs near the middle, with each adjacent pair of legs crossbraced by flexible non-resilient cords (71L, 71R, 71B) between the bottom of each leg and the approximate junction between each adjacent leg and the pack frame. The system is comprehensive, including pallet (267), solvent jar (268) and brush racks (191, 193), all suspended from the pack frame exterior. All paint supplies are securely held, readily accessible from the painting position in front. The canvas is rapidly moved up and down by pivoting canvas supports (300) on the legs, and a canvas support rig (376) sliding on a mast (37) above the legs. Canvas upper corners can be stabilized with a canvas stabilizer rig.
