Abstract
Abstract A portable submerged structure uses fluid pressure to extend a plurality oflexible conduits until the conduits become rigid. In such a rigid configuration the flexible conduits provide a rigid support which is independent of any further moorings or other conventional structure used to obtain rigidity. The invention discloses the use of an open form of independent conduits as well as conduits which are joined to provide a closed geometric figure. A packaging and deploying system using a fluid released container is also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
160 words
A portable submerged structure for establishing stable interrelationships between objects supported thereby comprising: rigid plenum chamber means for establishing a volume of relatively high pressure; aperture means communicating with the interior of said plenum chamber means for providing fluid flow and pressure transfer therefrom; conduit means attached to said plenum chamber in fluid tight relation and in cooperation with said aperture means said conduit means being made of a flexible material so as to be distended by the fluid pressure and fluid flow transmitted thereto via said aperture means for forming a single fluid vessel comprised of structural members effectively connected to the objects for support thereof; f fluid source means connected to said plenum chamber means for timely supply of fluid thereto; and pressure regulator means connected to said plenum chamber means and communicating between the exterior and interior thereof for keeping the fluid pressure within predetermined limits during periods of fluid supply thereto by said fluid source means.
Claim 2
Dependent Claim
160 words
A portable submerged structure for establishing stable interrelationships between objects supported thereby comprising: rigid plenum chamber means for establishing a volume of relatively high pressure; aperture means communicating with the interior of said plenum chamber means for providing fluid flow and pressure transfer therefrom; conduit means attached to said plenum chamber in fluid tight relation and in cooperation with said aperture means said conduit means being made of a flexible material so as to be distended by the fluid pressure and fluid flow transmitted thereto via said aperture means for forming a single fluid vessel comprised of structural members effectively connected to the objects for support thereof; f fluid source means connected to said plenum chamber means for timely supply of fluid thereto; and pressure regulator means connected to said plenum chamber means and communicating between the exterior and interior thereof for keeping the fluid pressure within predetermined limits during periods of fluid supply thereto by said fluid source means.
Claim 3
Dependent Claim
19 words
A portable submerged structure according to claim 1 in which said plenum chamber is made of a lightweight metal.
Claim 4
Dependent Claim
30 words
A portable submerged structure according to claim 1 in which said conduit means is fabricated of a lightweight, woven fabric impregnated with a plastic material to render it fluid light.
Claim 5
Dependent Claim
18 words
A portable submerged structure according to claim 3 in which said woven fabric is made of synthetic fibers.
Claim 6
Dependent Claim
29 words
A portable submerged structure according to claim 4 in which said conduit means formed fillable vessel is fashioned of bonded and taped segments to have a generally triangular shape.
Claim 7
Dependent Claim
29 words
A portable submerged structure according to claim 4 in which said conduit means formed fillable vessel is fashioned of bonded and taped segments to have a generally polygonal shape.
Claim 8
Dependent Claim
16 words
A portable submerged structure according to claim 4 in which said polygonal shape is a pentadecagon.
Claim 9
Dependent Claim
20 words
A portable submerged structure according to claim 4 in which said fluid source means is an electrically operated fluid pump.
Claim 10
Dependent Claim
27 words
A portable submerged structure according to claim 8 in which said fluid pump supplies fluid to the aforesaid plenum chamber through a stand pipe and check valve.
Claim 11
Dependent Claim
20 words
A portable submerged structure according to claim 1 in which said pressure regulator means includes a high-volume fluid relief valve.
Claim 12
Dependent Claim
77 words
A portable submerged structure according to claim 1 further including: float means for providing buoyant support for said structure; a predetermined length of line connected between said float means and said plenum chamber, whereby said chamber is suspended beneath the surface of a body of fluid in which the structure is submerged; and a plurality of cover segments extending between said float means and the aforesaid fluid source means to form a housing enclosing the aforerecited means.
Claim 13
Dependent Claim
35 words
A portable submerged structure according to claim 11 further including a a fluid actuated release mechanism connecting the plurality of cover segments, whereby deployment and storage of the portable submerged structure may be conveniently facilitated.
