  • Patent number: 3994102
    Abstract: An elongated inflated or inflatable element including closed loops at each end. The element has certain broad dimensional relationships between its loop measurements and other measurements, and is intended to be used in connection with a plurality of other elements to make joints and form structures. A system comprising a plurality of inflated elements having joint means and capable of being joined and assembled into a large variety of different structures. The joint means are inherent in the inflated structure of the elements.
