Abstract
Abstract An inexpensive and lightweight folding paperboard beach chair is formed from a single scored blank of paperboard. The elongated paperboard body has two spaced-apart and transverse score lines which define a bottom leg support panel, a middle seat support panel, and a top back support panel wherein the bottom and top panels are adapted to be folded so as to overlay the middle panel. A plurality of spaced-apart foldable support panels extend across the back of the top back support panel to provide support for the panel when the chair is unfolded, and are further adapted to fold upon and overlay the top panel when the chair is folded. An aperture is provided adjacent to the side edge of each of the top, middle, and bottom panels and positioned so as to be in vertical registration and to thereby form a carrying handle when the chair is folded into its closed configuration with the top and bottom panels overlaying the middle panels thereof.
