Abstract:
A water spray hose assembly comprising:an elongated flexible hose having two ends, and an end connector secured to each end of said hose;said flexible hose comprising an elongated rubber water tube having an oval cross section that includes first and second symmetrical oval half sections integrally connected together to form two fold lines, and a flange (31A) extending radially outwardly from each fold line;a first nylon fiber covering (32) overlying said first oval half section; and a second nylon fiber covering (33) overlying said second oval half section; said nylon fiber coverings having edge areas thereof secured to the flanges on said rubber tube;each said end connector comprising a coupling having an externally threaded outer tubular section, and an inner tubular section protruding axially beyond said outer tubular section for telescopically receiving an end portion of said rubber water tube;each said end connector further comprising two semi-circular cross-section splints collectively encircling the associated end of the flexible hose;said splints having flat radial surfaces seatable against edge areas of the nylon fiber coverings, and elastic end sections (61) movable toward the inner tubular section of said coupling to exert a grip force on the hose;each said end connector further comprising an internally threaded collar screwable onto said outer tubular section; said collar having an inner edge (at 52B) that exerts a cam force on the elastic end sections of said semi-circular splints when the collar is screwed onto said outer tubular section.
