US Patent 8201550 Portable charcoal barbecue grill

A grill base is pivotally attached at a first end to a folding stand with three pivoting U-shaped supports and a center pivot. Two of the supports rest on the ground on casters or wheels. The third support slides and locks within L-shaped slots below the second end of the grill base held horizontally for cooking. An inserted charcoal tray is used to cook. The supports pivot together and stand vertically on the castors. The grill base pivots down parallel to the supports so that all are vertical for storage and transport.
