Abstract
An improved safety hose apparatus includes an inner hose having threaded connectors attached rotatably at each end thereof. An inner hose is disposed about the outer hose. The inner hose is alternatable between longitudinally expanded and contracted conditions. The outer hose includes a pair of resiliently expandable end coupling portions. Each end portion is selectively expanded to releasably grip the peripheral surface of a respective threaded connector. This seals the end of the apparatus so that water leaking through a rupture in the inner hose is retained within the outer hose.
Claims5
A safety hose apparatus for delivering water from a threaded spout of a hose bib to a threaded appliance or plumbing fixture inlet, said apparatus comprising:
- an inner hose having threaded connectors attached rotatably at each end thereof for selectively securing the inner hose to the threaded spout and threaded inlet, respectively;
- and
- an outer hose through which said inner hose extends, said outer hose being longitudinally flexible and alternatable between longitudinally expanded and contracted conditions, said outer hose carrying a pair of generally cylindrical pair of coupling portions at respective ends thereof, each coupling portion having an inner diameter that is less than the diameter of a respective one of said threaded connectors and being resiliently expandable diametrically such that said coupling portion may be selectively diametrically expanded and grippably interengaged with said associated connector whereby interengaging said coupling portions with said connectors seals said inner and outer hoses such that water leaking from said inner hose is contained within said outer hose, said coupling portions being selectively disengaged from said respective threaded connectors to permit unhindered rotation of said connectors relative to said outer hose so that said connectors may be threadably engaged with and disengaged from the spout and the inlet and that permits said outer hose to be longitudinally expanded.
