Abstract
Abstract A conduit assembly for cabling has a multiplicity of plastic tubes with outer polygonal cross sections having more than three sides and is intended for direct insertion in the ground in a compact bundle in which there is practically no free space which can serve for water drainage. The tubes are connected with webs which are flexible and are so oriented that they are linearly aligned in an open array of the tubes so that the tubes are coplanar and can be coiled or coiled onto a drum or uncoiled from a drum.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A conduit assembly for direct in-ground positioning for cabling, said assembly comprising: a multiplicity of mutually parallel plastic tubes having regular polygonal outer cross sections defined by at least four angularly adjoining sides and positioned to interfit with one another with said sides of said tubes in contact with one another in a configuration of said assembly as a compact bundle of said tubes wherein a plurality of said tubes define a pocket complementarily receiving at least one other of said tubes so that said bundle is free from interstices between said tubes of said compact bundle; and respective flexible webs formed on said tubes and linearly connecting said tubes together so that said tubes are connected in a coplanar array upon opening of said compact bundle.
Claim 2
Dependent Claim
127 words
A conduit assembly for direct in-ground positioning for cabling, said assembly comprising: a multiplicity of mutually parallel plastic tubes having regular polygonal outer cross sections defined by at least four angularly adjoining sides and positioned to interfit with one another with said sides of said tubes in contact with one another in a configuration of said assembly as a compact bundle of said tubes wherein a plurality of said tubes define a pocket complementarily receiving at least one other of said tubes so that said bundle is free from interstices between said tubes of said compact bundle; and respective flexible webs formed on said tubes and linearly connecting said tubes together so that said tubes are connected in a coplanar array upon opening of said compact bundle.
Claim 3
Dependent Claim
22 words
The conduit assembly defined in claim 1 wherein adjacent ones of said sides of each of said tube adjoin at respective edges.
Claim 4
Dependent Claim
22 words
The conduit assembly defined in claim 2 wherein said webs are formed unitarily on said tubes at respective ones of said edges.
Claim 5
Dependent Claim
16 words
The conduit assembly defined in claim 2 wherein said tubes are of rectangular outer cross section.
Claim 6
Dependent Claim
16 words
The conduit assembly defined in claim 4 wherein said tubes are of square outer cross section.
Claim 7
Dependent Claim
16 words
The conduit assembly defined in claim 2 wherein said tubes are of hexagonal outer cross section.
Claim 8
Dependent Claim
16 words
The conduit assembly defined in claim 2 wherein said tubes are of circular inner cross section.
Claim 9
Dependent Claim
16 words
The conduit assembly defined in claim 2 wherein said tubes are of polygonal inner cross section.
Claim 10
Dependent Claim
16 words
The conduit assembly defined in claim 8 wherein said tubes are of regular-polygon inner cross section.
Claim 11
Dependent Claim
56 words
The conduit assembly defined in claim 2 wherein said coplanar array has end tubes at ends of said array and inner tubes between said end tubes, said inner tubes being connected together and to said end tubes by respective ones of said webs formed at diametrically opposite edges of at least some of said inner tubes.
Claim 12
Dependent Claim
26 words
The conduit assembly defined in claim 10 wherein said end tubes are formed with means for retaining said tubes in said configuration of said compact bundle.
Claim 13
Dependent Claim
15 words
The conduit assembly defined in claim 2 wherein said assembly comprises four of said tubes.
Claim 14
Dependent Claim
15 words
The conduit assembly defined in claim 2 wherein said assembly comprises seven of said tubes.
