Abstract
Abstract A long corrugated pipe bus conductor to be laid vertically in a high-storied building has the conductors of branching lines bonded thereto at predetermined intervals. The interval may be so selected as to correspond to the height of one story of the building. Each of the branching lines leads to an electrical equipment such as a switchboard on each story.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A corrugated busline to be laid vertically in a high storied building comprising: a flexible long pipe conductor having a corrugated inner and outer surface, an insulating layer coated on said outer surface of said conductor, said insulating layer having a corrugated outer surface similar to said conductor and being bare at intervals corresponding in spacing to each story of the building in the longitudinal direction of said conductor, flexible electric branching wires bonded to said flexible conductor at the bare portions thereof, and an insulating layer totally covering each of the exposed conductors and the bared area of said bonding portions.
Claim 2
Dependent Claim
102 words
A corrugated busline to be laid vertically in a high storied building comprising: a flexible long pipe conductor having a corrugated inner and outer surface, an insulating layer coated on said outer surface of said conductor, said insulating layer having a corrugated outer surface similar to said conductor and being bare at intervals corresponding in spacing to each story of the building in the longitudinal direction of said conductor, flexible electric branching wires bonded to said flexible conductor at the bare portions thereof, and an insulating layer totally covering each of the exposed conductors and the bared area of said bonding portions.
Claim 3
Dependent Claim
80 words
A corrugated bus line to be laid vertically in a high storied building comprising: a long flexible pipe conductor having a corrugated inner and outer surface and branching conductors bonded to said flexible pipe conductor at an interval corresponding in spacing to each story of the building, an elongated reinforcing wire arranged axially in said conductor through the entire length thereof, said pipe conductor being retained to said wIre by means of retaining members arranged at intervals in said pipe.
Claim 4
Dependent Claim
80 words
A corrugated bus line to be laid vertically in a high storied building comprising: a long flexible pipe conductor having a corrugated inner and outer surface and branching conductors bonded to said flexible pipe conductor at an interval corresponding in spacing to each story of the building, an elongated reinforcing wire arranged axially in said conductor through the entire length thereof, said pipe conductor being retained to said wIre by means of retaining members arranged at intervals in said pipe.
Claim 5
Dependent Claim
54 words
A corrugated bus line as defined in claim 2, and further including an insulating layer coated on said outer surface of said conductor, said layer having a corrugated outer surface similar to said conductor and being bare at spaced intervals for reception of said branching conductors, and an insulating layer covering said bonded portion.
Claim 6
Dependent Claim
16 words
A corrugated bus line as defined in claim 3 wherein said branching conductors are terminal plates.
Claim 7
Dependent Claim
28 words
A corrugated pipe bus line according to claim 2, wherein said pipe conductor is provided at least at one end thereof with a terminal connector for power feeding.
