US 6,637,777 B2 · Low-profile conduit elbow

Abstract

A conduit elbow assembly includes a hollow conduit piece having an end with an outer diameter, a body and a cap. The body has a first connective end with an end bore at the first connective end receiving the hollow conduit piece therein. A male fitting is located at the first connective end, the male fitting having an outer surface and an end which extends into the end bore. The outer surface of the male fitting has barbs which engage and retain the end of the hollow conduit piece thereon. The cap is attached ton the body and has a plurality of tapered projections, of which two are diametrically opposed to each other relative to the outer diameter of the hollow conduit piece. The two tapered projections form a wedge fit with the outer diameter of the hollow conduit piece.

A conduit elbow assembly for connection to a hollow conduit piece, said conduit elbow assembly comprising:

a body having a first connective end, an end bore at said first connective end configured for receiving the hollow conduit piece therein, said end bore having a bore diameter, a male fitting located at said first connective end, said male fitting having an outer surface and an end which extends into said end bore, said outer surface having barbs for engaging and retaining the hollow conduit piece thereon;
and
a cap attached to said body, said cap having a plurality of tapered projections, two said tapered projections being diametrically opposed to each other relative to said bore diameter, said two said tapered projections adapted to form a wedge fit with the hollow conduit piece received in said end bore.

A method of forming a conduit assembly, comprising the steps of:

providing a hollow conduit piece having an inner conduit surface, an outer conduit surface and an end;
providing a conduit elbow assembly including a body having a first connective end, an end bore at said first connective end, a male fitting located at said first connective end, said male fitting having an outer surface and an end which extends into said end bore, said outer surface having barbs thereon, and a cap having a plurality of tapered projections, two said tapered projections being diametrically opposed to each other relative to said end bore;
inserting said end of said hollow conduit piece in said end bore and onto said outer surface of said male fitting, at least a portion of said barbs engaging said inner conduit surface;
and
mounting said cap upon said body and said hollow conduit piece and thereby wedge-fitting said two said tapered projections against said outer conduit surface.
