Inflatable lifesize toy structure with interlocking elements

Claim 1

A toy construction kit for erecting structures large enough to be played in by children comprising: a plurality of inflatable elements, said elements forming a cylendrical shape in the elongated direction, said elements being generally round in cross section, said elements constructed of flexible walls and having two sealed ends forming an enclosed gas chamber within; said elements having at least one air valve as a means of inflation and deflation of said elements; said elements having at least one convex recess thereof inclined inwardly from said flexible exterior of said element toward the interior of said enclosed gas chamber whereby a symmetrical half circle is formed of an approximate diameter of said element, said recess having an axis that is perpendicular to the axis of said element, said recess being a means of the perpendicular coupling of one said element with another said element; said elements stacked vertically one with another in a perpendicular alternating pattern whereby each stacked element is seated into said recess of an adjacent perpendicular element thereby interlocking each perpendicular adjacent element, one with another; a ring element, said ring element being less in diameter than the diameter of the cross section of said element, is a means for forming a window in a wall of said toy structure.
