Cable-guide assembly of plastic tubes joined by webs

Details

Inventors: Vogelsang, Horst;
Assignee: Dipl.-Ing. Dr. Ernst Vogelsang GmbH & Co. KG (Herten/Westf., DE)
Primary Examiner: Bryant, III; James E.

Attorney, Agent or Firm: Dubno; Herbert

A cable-guide assembly of particular utility in ground subsidence regions consists of three tubes extruded simultaneously with the connecting webs and abutting at hexagonal segments form with two angularly adjoining surfaces. A subsequently applied sealing strip or a sealing strip formed on one of the tubes not interconnected by a connecting web can bridge between the two tubes which are not interconnected by such webs when the bundle is formed.

DETAILED DESCRIPTION I claim: 1.
A cable-guide conduit assembly comprising: a group of only three plastic conduit tubes having identical outer cross sections of the configuration of part of a regular hexagon defined by two angularly adjoining flat sides; flexible connecting webs of plastic formed unitarily with said tubes and interconnecting same so that said tubes can be selectively disposed in a plane and rolled by bending at said webs into a bundle so that the two angularly adjoining flat sides of each conduit tube flatly contact respective flat sides of the other two tubes with at most small contact gaps between the mutually contacting surfaces and all other outer surfaces of said conduit tubes are free from contact with other tubes of said assembly and bundle, said webs each spanning across a free space between two tubes interconnected by each web and sealing a respective said contact gap which opens at the respective free space said tubes in said bundle forming apart from said gaps a massive core and said tubes having outer configurations comprised of a segment of circular arc configuration connected to a segment of a regular hexagon, and said segment of circular arc configuration being semicircular in cross section and said segment of a regular hexagon being a segment of half a regular hexagon.
2.
A cable-guide conduit assembly comprising: a group of only three plastic conduit tubes having identical outer cross sections of the configuration of part of a regular hexagon defined by two angularly adjoining flat sides; flexible connecting webs of plastic formed unitarily with said tubes and interconnecting same so that said tubes can be selectively disposed in a plane and rolled by bending at said webs into a bundle so that the two angularly adjoining flat sides of each conduit tube flatly contact respective flat sides of the other two tubes with at most small contact gaps between the mutually contacting surfaces and all other outer surfaces of said conduit tubes are free from contact with other tubes of said assembly and bundle, said webs each spanning a cross a free space between two tubes interconnected by each web and sealing a respective said contact gap which opens at the respective free space, said tubes in said bundle forming apart from said gaps a massive core
