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. |

Claims1. A structure formed by at least a pair of inflated, hollow, elongated elements of impermeable flexible closed contour sheet material, comprising a valve on each of said elements, each of said elements having a main portion forming a generally cylindrical shape in the elongated direction, said elements having completely closed continuous loops at each extreme end of said main portion, said loops defining and enclosing a hole of continuous unbroken circumference, each of said holes having a diameter equal to approximately the greatest transverse diameter of said main portion of a corresponding element, each of said loops having an outer diameter greater than said transverse diameter of said main portion of said corresponding element, and each of said hole circumferences having the same configuration as said element main portion on a plane along said transverse diameter, said elements joined each to the other to form said structure whereby one of said loops of one element is deformed to pass through said hole of another of said inflated elements and expanded to lockingly engage said elements in a releasable manner each to the other. 2. The structure formed by at least a pair of inflated, hollow, elongated elements of impermeable flexible closed contour sheet material as recited in claim 1, wherein each said loop has a largest overall outer diameter greater than the largest transverse diameter of said main portion, and each said loop has a thickness at right angles to the plane of said overall diameter, said thickness being less than the greatest transverse diameter of said main portion. 3. The structure formed by at least a pair of inflated, hollow, elongated elements of impermeable flexible closed contour sheet material as recited in claim 2, wherein said loops are also sealed together around the edges of each of said holes. 4. The structure formed by at least a pair of inflated, hollow, elongated elements of impermeable flexible closed contour sheet material as recited in claim 1, wherein at least one loop of said inflated element is inserted completely through one hole in another of said inflated elements to form a joint between said two elements. 5. The structure formed by at least a pair of inflated, hollow, elongated elements of impermeable flexible closed contour sheet material as recited in claim 1, combined with a plain inflated element, said plain inflated element being generally cylindrical, elongated, hollow of impermeable flexible sheet material, and including a valve, and having pointed corners at its ends, one of said ends of said plain elongated inflated element being inserted completely through said hole in one of said inflated elements including a loop, to form a joint between said plain and said looped inflated elements. 6. The combination set forth in claim 5 wherein an additional said looped inflated element is provided and said end of said plain inflated element is inserted additionally through one hole in said additional looped inflated element, to form a three element joint. |
