Abstract
The modular conduit unit formed from at least four conduits secured together in spaced relationship by means of a plurality of spaced star-shaped spacer elements. The star-shaped spacer elements are each formed with four equally spaced hollow projections that terminate in end walls and have curved side walls. The curved side walls of adjacent projections merge to form outer walls of the element that are in the form of cylindrical segments. An integral reinforcing member interconnects said outer walls at points spaced from said end walls and a line of weakness is found in each of said end walls and extends substantially longitudinally of the cylindrical segments. The line of weakness facilitates breaking of the star-shaped member for replacement of a conduit.
Claims6
A modular conduit unit composed of at least four conduits secured together in spaced relationship with their longitudinal axis substantially parallel by at least 3 spaced star-shaped spacer elements interposed between the conduits, each of said star-shaped spacer elements being provided with four equally spaced hollow projections that terminate in an end wall and have curved side walls, said curved side walls of adjacent projections merging to form outer walls substantially in the form of circular cylindrical segments, an intergral substantially annular reinforcing member interconnecting said outer walls at points spaced inwardly from said end wall and defining an inner free space, said end wall, said curved side walls of each of said projections and said reinforcing member defining a free space in each of said projections, each of said end walls being provided with a line of weakness extending substantially axially of said cylindrical sections, the outer face of said cylindrical sections being in face-to-face relationship to and adhesively secured directly with said conduits and there being a weakness at each point of contact between said circular cylindrical segments and said annular member whereby a damaged conduit of said unit may be replaced by breaking the star-shaped spacer along the appropriate weakness areas.
