Abstract: A segmented inflatable structure device includes a plurality of body segments positionable together to join into an assembled condition to form a structure when inflated. Each body segment has at least one opening. Each opening in each body segment is adjacent to and aligned with an associated opening on an adjacently positioned one of the body segments defining an interior space when the body segments are in the assembled condition to form the structure. Each of a plurality of segment fasteners releasably couples adjacently positioned body segments together in the assembled condition. A main air inlet is positioned in one of the body segments for connection to an air pump for injecting air into the interior space whereby the structure is inflated.
