Abstract
Abstract A collapsible cooking rack arrangement comprises a first rack for supporting food to be cooked, a second rack for supporting a heat source and a pair of end supports for holding the racks in mutually vertically spaced, horizontally parallel relationship with the first rack above the second rack. The end supports each include means for releasably supportingly engaging the first rack so that the latter is readily removable, and the end supports are pivotally connected to opposite ends of the second rack, so that the end supports are pivotably between collapsed positions, in which they are compactly folded with the second rack, and erected positions in which they can be engaged with the first rack. Locking member are releasably engageable with eyes on the end supports for locking the latter in the erected positions, and the racks and the end supports are made of wire. The arrangement is inexpensive to manufacture, light and compact to transport and stable when erected.
