Abstract
Abstract A knock down foundation for a flotation sleep system comprising a plurality of interlocking sections combining to form a rectangular base. A planar support made up of separate parts may be disposed over the base covering substantially the entire exposed sheet. A softsided waterbed or other sleeping systems is then laid on top of the sheet. A plurality of feet are provided on the undersurface of said sections for supporting the base on a supporting surface. Headboard brackets are provided at one end of the base for attaching a headboard thereto. A plurality of hooks are provided on the bottom of the sections at spaced locations for receiving grommets of upholstery thereon. The sheet and headboard brackets may be fastened to the sections by screws or the like. The entire apparatus can be quickly and easily knocked down or set up, is light in weight and easy to ship in a compact form.

Total Claims: 8
Claim 1
Independent Claim
347 words
In a knock down lightweight foundation for a flotation bed comprising: a plurality of elongated side supports; first removable interconnecting means associated with a first pair of said side supports to form a linear first side of said foundation; second removable interconnecting means associated with a second pair of said supports to form a linear second side of said foundation; a pair of elongated end supports; third removable interconnecting means associated with one end of said first side of said foundation interconnecting said first side with one of said end supports; fourth removable interconnecting means associated with one end of said second side of said foundation interconnecting said second side to the free end of said one of said end supports; fifth removable interconnecting means associated with the other end of said first side of said foundation interconnecting said first side with the other of said end supports; sixth removable interconnecting means associated with the other end of said second side of said foundation interconnecting said second side with the free end of said end supports thereby forming an open rectangular framework; and a mid support extending between said first and second sides, said first and second removable interconnecting means also being removably interconnected to the free ends of said mid support, said first interconnecting means including a block having a first tongue thereon extending in a direction toward one end of said mid support, a second tongue extending in a direction toward one of said side supports on said first side and a third tongue extending in a direction toward the other of said side supports on said first side, and said second interconnecting means includes a block having a first tongue thereon extending in a direction toward the other end of said mid support, a second tongue extending in a direction toward one of said side supports on said second side, and a third tongue extending in a direction toward the other end of said side supports on said second side, and grooves on said mid support and said side supports receiving said tongues therein.
