Abstract
Abstract A reinforced inflatable building in which an elongated fabric shell, anchored and sealed to the ground around its periphery, is supported by filling the enclosed volume with air at above atmospheric pressure. The entire outer surface of the building is overlayed with a cable network wherein the individual cables are arranged to form two intersecting sets of parallel cable lines. Each set of cable lines is oriented at an acute angle to the longitudinal axis of the building.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
177 words
A reinforced inflatable building comprising in combination an inflatable fabric skin anchored to the ground at its periphery and adapted to be self-supporting upon filling of the interior of the building with air under pressure, a cable network overlying the outer surface of said skin including a plurality of cables lying along first and second intersecting sets of parallel cable lines, each of said cable lines extending between peripheral ground anchors, means for rigidly clamping the intersecting cables together at the points of intersection, said cable network comprising a number of sections interconnected at connection points, and connectors provided at said connection points for interconnecting the cables in adjacent cable sections, said sections comprising a number of cables which extend along a cable line in one of said sets through a connector at a connection point and turn to extend along a cable line in the other of said sets, each end of the cables in each of said sections terminating at ground anchors at the edge of the section positioned at the periphery of the building.
Claim 2
Dependent Claim
177 words
A reinforced inflatable building comprising in combination an inflatable fabric skin anchored to the ground at its periphery and adapted to be self-supporting upon filling of the interior of the building with air under pressure, a cable network overlying the outer surface of said skin including a plurality of cables lying along first and second intersecting sets of parallel cable lines, each of said cable lines extending between peripheral ground anchors, means for rigidly clamping the intersecting cables together at the points of intersection, said cable network comprising a number of sections interconnected at connection points, and connectors provided at said connection points for interconnecting the cables in adjacent cable sections, said sections comprising a number of cables which extend along a cable line in one of said sets through a connector at a connection point and turn to extend along a cable line in the other of said sets, each end of the cables in each of said sections terminating at ground anchors at the edge of the section positioned at the periphery of the building.
Claim 3
Dependent Claim
23 words
A reinforced inflatable building according to claim 1, wherein said connectors are readily detachable from at least one of the cables interconnected thereby.
Claim 4
Dependent Claim
23 words
A reinforced inflatable building according to claim 2, wherein said connectors include hook means for loosely engaging each of the cables interconnected thereby.
Claim 5
Dependent Claim
44 words
A reinforced inflatable building according to claim 3, wherein said connectors include a pair of interconnected hook members and resilient means positioned to normally close the opening in each hook member to allow insertion of a cable therein and to retain the cable therein.
Claim 6
Dependent Claim
30 words
A reinforced inflatable building according to claim 4, wherein said connectors include a bar member interconnecting said hook members and means for attaching said bar member to said fabric skin.
Claim 7
Dependent Claim
137 words
A reinforced inflatable building, comprising in combination an inflatable fabric skin having a rectangular floor plan including end sections each in the general form of a truncated quarter sphere, said skin being anchored to the ground at its periphery and adaptable to be self-supporting upon filling of the interior of the building with air under pressure, a plurality of cables arranged to form a cable network overlying the entire outer surface of the skin, the cables in the network forming only first and second sets of parallel cable lines extending over the surface of the skin between peripheral ground anchors, said first and second sets of cable lines intersecting substantially at right angles and being positioned at equal angles to the longitudinal axis of said building, and means for interconnecting the cables at the points of intersection.
Claim 8
Dependent Claim
137 words
A reinforced inflatable building, comprising in combination an inflatable fabric skin having a rectangular floor plan including end sections each in the general form of a truncated quarter sphere, said skin being anchored to the ground at its periphery and adaptable to be self-supporting upon filling of the interior of the building with air under pressure, a plurality of cables arranged to form a cable network overlying the entire outer surface of the skin, the cables in the network forming only first and second sets of parallel cable lines extending over the surface of the skin between peripheral ground anchors, said first and second sets of cable lines intersecting substantially at right angles and being positioned at equal angles to the longitudinal axis of said building, and means for interconnecting the cables at the points of intersection.
Claim 9
Dependent Claim
106 words
A reinforced inflatable building according to claim 6, wherein said cable network comprises a number of sections interconnected at connection points and wherein connectors are provided at said connection points for interconnecting the cables in adjacent network sections, said sections comprising a number of cables which extend along a cable line in one of said sets through a connector at a connection point and turn to extend along a cable line in the other of said sets, each end of each of the cables in each of said sections terminating at ground anchors at the edge of the section positioned at the periphery of the building.
Claim 10
Dependent Claim
83 words
A reinforced inflatable building according to claim 6, wherein each of said end sections of said skin is formed from a triangular end panel and two right triangular side panels, said end panel having two equal sides and a base lying along the peripheral end edge of the building, each of said side panels having its hypotenuse connected to one of said equal sides of said end panel and having its base lying along the end portion of the side of the building.
Claim 11
Dependent Claim
26 words
A reinforced inflatable building according to claim 8, wherein said connectors are formed to be readily detachable from at least one of the cables interconnected thereby.
Claim 12
Dependent Claim
23 words
A reinforced inflatable building according to claim 9 wherein said connectors include hook means for loosely engaging each of the cables interconnected thereby.
