Segmented fitting for convoluted hose

Claim 1

A reusable fitting for convoluted hose having a plurality of adjacent annula convolutions characterized by its ability to establish an efficient seal to the hose with a minimum of special equipment an produce a low profile free of adrupt radial surfaces comprising, in combination, a tubular nipple having a longitudinal axis, an inner end adapted to be inserted into the end of a convoluted hose and an outer end, conduit attachment means defined on said nipple outer end, socket retaining means defined on said nipple intermediate said inner and outer ends, said inner end including an annular shoulder adjacent said socket retaining means, a terminal end defining the termination of said inner end and an intermediate portion between said shoulder and said terminal end, at least one annular ridge defined on said inner end adjacent said terminal end adapted to be received within a hose convolution, a plurality of annular serrations defined on said inner end intermediate portion, a circumferentially extending socket encompassing said nipple inner end, said socket comprising at least three identical segments, each segment having an outer surface, an inner end, an outer end, a concave inner surface and lateral edges intersecting said inner and outer ends, a plurality of serrations defined on each segments' inner surface inwardly projecting therefrom, a circumferentially extending protrusion defined on each segment outer surface intermediate said segment's inner and outer ends and intersecting the associated segments' lateral edges being of a rounded convex configuration in a cross-sectional plane containing the nippled axis, and releasable fastening means within said protrusions interconnecting adjacent segments comprising a threaded bore intersecting one lateral edge of each segment, a counterbored bore intersecting the other lateral edge of each segment in opposed and aligned relationship to a threaded bore, at least one circumferentially extending threaded screw extending between adjacent segments through the adjacent opposed lateral edges thereof, said screw having a head received within said counterbored bore and a threaded stem received within the aligned threaded bore, said interconnected segments defining an annular socket circumscribing said nipple inner end having a hose mounted thereon, said segments' serrations compressing the hose upon said nipple's inner end serrations.
