Abstract
Abstract A load-support module comprises first and second frame structures of rectangular plan form disposed one above the other on a common central axis, with load support members attached to and extending between the structures. The frame structures are such that the modules can be stacked one on another in nested relationship. The modules are disposed in close-packed rows on a base frame structure, forming a load-support surface. Contiguous modules are demountably secured to one another and are each provided with fitted floor members. The entire structure is provided with a demountable, peripheral flexible skirt. A number of such structures can be combined to transport very large objects.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A modular, demountable fluid-cushion-supported vehicle, comprising: an openwork base frame structure; a plurality of load-support modules disposed in close-packed rows on the base frame structure so as to form a load-support surface, each module comprising first and second openwork frame structures of rectangular plan form disposed one above the other on a common central axis, with load support members attached to and extending between the first and second frame structures, said first and second frame structures having substantially the same plan form but differing dimensions so that the sides of one of the first and second frame structures are spaced further from the central axis than the sides of the other of the first and second frame structures, whereby the modules can be stacked together one on another in nested relationship when disassembled, adjacent rows of the nested modules being staggered relative to each other; floor members fitted into the lowermost of the first and second frame structures of the modules; means for demountably securing contiguous modules together; and, a flexible skirt demountably attached to the periphery of the base frame structure.
Claim 2
Dependent Claim
182 words
A modular, demountable fluid-cushion-supported vehicle, comprising: an openwork base frame structure; a plurality of load-support modules disposed in close-packed rows on the base frame structure so as to form a load-support surface, each module comprising first and second openwork frame structures of rectangular plan form disposed one above the other on a common central axis, with load support members attached to and extending between the first and second frame structures, said first and second frame structures having substantially the same plan form but differing dimensions so that the sides of one of the first and second frame structures are spaced further from the central axis than the sides of the other of the first and second frame structures, whereby the modules can be stacked together one on another in nested relationship when disassembled, adjacent rows of the nested modules being staggered relative to each other; floor members fitted into the lowermost of the first and second frame structures of the modules; means for demountably securing contiguous modules together; and, a flexible skirt demountably attached to the periphery of the base frame structure.
Claim 3
Dependent Claim
20 words
A vehicle as claimed in claim 1, wherein the module has lateral and longitudinal vertical cross-sections of generally trapezoidal form.
Claim 4
Dependent Claim
40 words
A vehicle as claimed in claim 1, wherein each of the first and second frame structures is of "L"-section material with the limbs of the first frame structure disposed outwardly and the limbs of the second frame structure disposed inwardly.
Claim 5
Dependent Claim
21 words
A vehicle as claimed in claim 1, further comprising inflatable load-support members disposed on the load-support surface formed by the modules.
Claim 6
Dependent Claim
43 words
Apparatus for retrieving disabled aircraft, comprising: a plurality of fluid-cushion-supported vehicles, each as claimed in claim 1; means for linking the vehicles together; means for stabilizing the disabled aircraft during movement of the vehicles; and, means for transporting the vehicles over the ground.
