Abstract
An inflatable shelter includes a flexible membrane, a first elongate inflatable tube supported by the flexible membrane and a second elongated inflatable tube supported by the flexible membrane. The first tube has first and second axial ends and a first intermediate portion between the first and second axial ends. The second tube has third and fourth axial ends and a second intermediate portion between the third and fourth axial ends. The first, second, third and fourth axial ends terminate in a plane. The first and second intermediate portions converge towards one another such that the first and second tubes form four legs supporting the membrane. The flexible membrane preferably includes first and second sleeves defining first and second lumens receiving the first and second inflatable tubes, respectively, and a plurality of wall panels coupled to and extending between the first and second sleeves. The first and second lumens of the first and second sleeves are separated by at least one divider panel extending substantially parallel to the first and second tubes. The first and second tubes are insertable into and removable from the first and second sleeves, respectively, such that the first and second tubes are replaceable.
