Abstract
Abstract A conduit system comprising a conduit openable along its length, from either of its ends, or intermediate its ends. The conduit includes an outer body or shell fabricated of substantially inelastic metal, and an inner flexible liner. The conduit defines a seam along its length, and the seam sections are connectable together by means of spaced hook members integrally connected to the body portion of one seam section and each projecting into an opening defined adjacent the opposite seam section. The outer body includes annular corrugations spaced along its length and the corrugations are serrated to enable the outer body to bend.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
93 words
A fluid flow device comprising an elonGated sheet of material including mating interlocking seams along its opposite longitudinal edges, said sheet of material being deformable laterally of its length to permit said seams to move into and out of abutting interlocking relationship with each other to form said sheet of material into a tube, said sheet of material being shaped to deform along its length when in its tubular configuration to permit said tube to bend along its length, and including a layer of fluid impervious sealing material bonded to its inner surface.
Claim 2
Dependent Claim
93 words
A fluid flow device comprising an elonGated sheet of material including mating interlocking seams along its opposite longitudinal edges, said sheet of material being deformable laterally of its length to permit said seams to move into and out of abutting interlocking relationship with each other to form said sheet of material into a tube, said sheet of material being shaped to deform along its length when in its tubular configuration to permit said tube to bend along its length, and including a layer of fluid impervious sealing material bonded to its inner surface.
Claim 3
Dependent Claim
42 words
The invention of claim 1 wherein said the tube formed by said sheet of material includes generally annular corrugations spaced along its length, and connecting means adjacent said seam strips and intermediate said corrugations for holding said seam strips in abutting relationship.
Claim 4
Dependent Claim
85 words
A fluid flow conduit for flowing pressurized fluid comprising a tubular outer body fabricated from a relatively rigid material and a tubular inner sealing liner attached to the inner surface of said outer body and fabricated from a relatively flexible fluid impervious material, said outer body and inner sealing liner defining a seam extending along the length of said conduit which includes mating seam sections constructed and arranged to connect with and disconnect from each other and close or open said conduit along its length.
Claim 5
Dependent Claim
85 words
A fluid flow conduit for flowing pressurized fluid comprising a tubular outer body fabricated from a relatively rigid material and a tubular inner sealing liner attached to the inner surface of said outer body and fabricated from a relatively flexible fluid impervious material, said outer body and inner sealing liner defining a seam extending along the length of said conduit which includes mating seam sections constructed and arranged to connect with and disconnect from each other and close or open said conduit along its length.
Claim 6
Dependent Claim
42 words
The fluid flow conduit of claim 3 and wherein one of said seam sections includes a series of spaced hook members, and the other of said seam sections includes a series of spaced openings sized and positioned to receive said hook members.
Claim 7
Dependent Claim
45 words
The fluid flow conduit of claim 4 and wherein said outer body is formed with a series of externally protruding corrugations extending generally transverse to the length of said conduit and spaced along the length of said conduit at intervals between said spaced hook members.
Claim 8
Dependent Claim
83 words
The fluid flow conduit of claim 3 and wherein said outer body is fabricated of spring steel and one of said seam sections includes a plurality of spaced hooks integrally formed with said outer body and extending beyond the edge of said inner sealing liner, and the other of said seam sections defines a plurality of spaced openings sized and positioned to receive said hooks, said inner sealing liner extending over and closing said spaced openings on the inner surface of said conduit.
Claim 9
Dependent Claim
82 words
A fluid flow conduit for flowing pressurized fluids comprising an outer rigidifying body and a pliable inner liner, separable seam extending along the length of said conduit for opening and closing said conduit along its length, said seam being constructed and arranged to maintain the edges of the outer rigidifying body in abutment with each other and the edges of said pliable liner at said seam in abutting, generally sealed relationship with each other when said conduit is closed along its length.
Claim 10
Dependent Claim
82 words
A fluid flow conduit for flowing pressurized fluids comprising an outer rigidifying body and a pliable inner liner, separable seam extending along the length of said conduit for opening and closing said conduit along its length, said seam being constructed and arranged to maintain the edges of the outer rigidifying body in abutment with each other and the edges of said pliable liner at said seam in abutting, generally sealed relationship with each other when said conduit is closed along its length.
Claim 11
Dependent Claim
40 words
The fluid conduit of claim 7 and wherein said outer rigidifying body comprises an elongated sheet including interlocking longitudinal edges, and a series of spaced convex corrugations formed in said sheet and extending laterally across the length of said sheet.
Claim 12
Dependent Claim
29 words
The fluid flow conduit of claim 7 and further characterized by said convex corrugations each defining a series of spaced slots therein extending across the length of said corrugations.
Claim 13
Dependent Claim
24 words
The fluid flow conduit of claim 7 and further including a cable connected to and extending along the length of said outer rigidifying body.
